DESCRIPTION OF THE EMBODIMENTS

To make the objectives, technical solutions and advantages of the present disclosure more clearly, the embodiments of the present disclosure are further described in detail below with reference to the accompanying drawings.

Although the present disclosure can easily be embodied in different forms of embodiments, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. Meanwhile, it should be understood that this specification should be regarded as an exemplary explanation of the principle of the present disclosure and is not intended to limit the present disclosure to what is described here.

Therefore, a feature pointed out in this specification will be used to describe one of the features of an embodiment of the present disclosure, rather than implying that each embodiment of the present disclosure must have the described features. In addition, it should be noted that many features are described in this specification. Although some features can be combined to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. As such, the illustrated combinations are not intended to be limiting unless otherwise specified.

In the embodiments shown in the accompanying drawings, the directions (such as up, down, left, right, front, and back) are used to explain that the structures and movements of various elements of the present disclosure are not absolute but relative. When these elements are located at positions shown in the accompanying drawings, these descriptions are suitable. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

Please referring to FIG. 1, FIG. 2 and FIG. 3, FIG. 1 is a schematic diagram of an incline device 10 according to an embodiment of the present disclosure, FIG. 2 is a schematic diagram of a bearing assembly 11 and a sliding assembly 12 according to an embodiment of the present disclosure; and FIG. 3 is a schematic diagram of exploded structures of a bearing assembly 11 and a sliding assembly 12 shown in FIG. 2. The incline device 10 may include a bearing assembly 11, and a sliding assembly 12.

The bearing assembly 11 may be configured to connect a running platform support, the bearing assembly 11 can be fixedly connected to one end of the running platform support, or one end of the running platform support is installed at one end, away from the ground, of the bearing assembly 11.

The sliding assembly 12 may be movably connected to the bearing assembly 11, the sliding assembly 12 and the bearing assembly 11 can slide relatively along a target direction, and the target direction intersects with the ground. Exemplary, the target direction includes a direction perpendicular to the ground. Through a sliding connection between the sliding assembly 12 and the bearing assembly 11, the bearing assembly 11 can slide relative to the sliding assembly 12, or the sliding assembly 12 can slide relative to the bearing assembly 11 to achieve extension and retraction of the incline device 10 in a direction perpendicular to the ground, thus driving one end of the running platform support to ascend or descend along the direction perpendicular to the ground by the incline device 10 to change an included angle between the running platform support and the ground. Exemplary, the bearing assembly 11 can slide relative to the sliding assembly 12 along a direction away from the ground to increase an overall height of the incline device 10, making a distance between one end of the running platform support and the ground increased. The bearing assembly 11 can slide relative to the sliding assembly 12 along a direction close to the ground to reduce an overall height of the incline device 10, making the distance between one end of the running platform support and the ground decreased.

The bearing assembly 11 may be provided with one first stopper 111, or multiple first stoppers 111 arranged along the target direction. The sliding assembly 12 may be provided with a second stopper 121, and the second stopper 121 is configured to be clamped with one of the first stoppers 111 in the bearing assembly 11 when the sliding assembly 12 slides to a designated position along the target direction.

Continuing to refer to FIG. 4, FIG. 4 is a schematic diagram of an internal structure of an incline device 10 according to an embodiment of the present disclosure. The second stopper 121 in the sliding assembly 12 in FIG. 4 may be clamped with one of the first stoppers 111 in the bearing assembly 11. The sliding assembly 12 can slide among multiple designated positions relative to the bearing assembly 11 along the target direction, and the multiple designated positions may be in one-to-one correspondence with the multiple first stoppers 111. When the sliding assembly 12 slides to any designated position along the target direction, the second stopper 121 in the sliding assembly 12 can be clamped with the first stopper 111 corresponding to the designated position, thus locking the bearing assembly 11 and the sliding assembly 12 to the current position. Exemplary, the number of the first stoppers 111 may be one, two, three, four, or more, which is not limited in the embodiment of the present disclosure.

Through the clamping of the first stopper 111 and the second stopper 121, the bearing assembly 11 and the sliding assembly 12 can be locked at the designated position to prevent a situation that the bearing assembly 11 still moves relative to the sliding assembly 12 after the sliding assembly 12 slides to the designated position relative to the bearing assembly 11 along a direction perpendicular to the ground, the stability of the incline device 10 can be improved, and the raised incline device 10 can stably support the running platform support.

Moreover, as the multiple first stoppers 111 can be arranged along the target direction, through the clamping of the first stopper 111 and the second stopper 121, a stroke distance of relative movement of the bearing assembly 11 and the sliding assembly 12 can be accurately controlled to accurately control the expansion and retraction degree of the incline device 10, thereby accurately controlling an inclination angle of the running platform support.

In an embodiment of the present disclosure, an included angle between the running platform support and the ground can be adjusted by the incline device 10, thus adjusting slope of the treadmill including the incline device 10 and the running platform support, and making the treadmill able to simulate various outdoor sports scenes through slope adjustment. Moreover, exercise intensity can be adjusted through multi-step slopes, making a user have diversified sports experiences. In addition, when the treadmill is not used, the incline device 10 can be lowered to reduce the overall occupied space of the treadmill and facilitate the user to store the treadmill.

In conclusion, an embodiment of the present disclosure provides an incline device 10 including a bearing assembly 11 and a sliding assembly 12. The sliding assembly 12 is movably connected to the bearing assembly 11, and the bearing assembly 11 is provided with at least one first stopper 111. When the sliding assembly 12 slides to the designated position along the target direction, the second stopper 121 in the sliding assembly 12 is clamped with the first stopper 111 in the bearing assembly 11. As such, through the clamping of the first stopper 111 and the second stopper 121, a stroke distance of relative movement of the bearing assembly 11 and the sliding assembly 12 can be accurately controlled to accurately control the expansion and retraction degree of the incline device 10, thereby accurately controlling an inclination angle of a running platform support. The structure is exquisite and easy to operate, which can solve the problem that a structure which is simple and can adjust a slope angle of a treadmill without a motor for driving is urgently needed in the prior art to meet use requirements of a user to simulate walking with different slopes, and achieve the effect of improving the applicability of the treadmill.

Referring to FIG. 3 and FIG. 4, in an alternative embodiment, the first stopper 111 may include a limiting slot c1, and the second stopper 121 may include a rotary latch 1211 and a locating part 1212. The limiting slot c1 and the locating part 1212 are arranged adjacent to each other, and the rotary latch 1211 is located at one side, away from the ground, of the locating part 1212.

Please referring to FIG. 5, FIG. 6 and FIG. 7, FIG. 5 is a schematic diagram of an internal structure of another incline device 10 according to an embodiment of the present disclosure, FIG. 6 is cross-sectional diagram of an internal structure of an incline device 10 shown in FIG. 5; and FIG. 7 is schematic diagram of an exploded structure of a sliding assembly 12 according to an embodiment of the present disclosure. In FIG. 5, a state of the incline device 10 is that the sliding assembly 12 slides to the designated position, and an end part of the rotary latch 1211 is inserted into the limiting slot c1.

When the sliding assembly 12 slides along the target direction, the rotary latch 1211 is located outside the limiting slot c1, and the rotary latch 1211 and the locating part 1212 are in a separated state, thus preventing the rotary latch 1211 from obstructing the relative sliding between the sliding assembly 12 and the bearing assembly 11.

When the sliding assembly 12 slides to the designated position along the target direction, the end part of the rotary latch 1211 is inserted into the limiting slot c1 and abutted against the locating part 1212, thus achieving the limiting of the sliding assembly 12 and the bearing assembly 11 and prevent the sliding assembly 12 and the bearing assembly 11 from sliding continuously.

It may be understood that as shown in FIG. 6, after the end part of the rotary latch 1211 is inserted into the limiting slot c1, as one end, away from the ground, of the bearing assembly 11 bears the running platform support, the running platform support applies pressure towards the ground to the bearing assembly 11, making the bearing assembly 11 apply pressure towards the ground to the rotary latch 1211 located in the limiting slot c1, and meanwhile, the locating part 1212 in the sliding assembly 12 can apply a supporting force away from the ground to the rotary latch 1211. As such, when a load is applied to the bearing assembly 11 from above, because the bearing assembly 11 and the sliding assembly 12 tend to slide relatively, a slot wall of the limiting slot c1 in the bearing assembly 11 and the locating part 1212 in the sliding assembly 12 can clamp the rotary latch 1211 to prevent the rotary latch 1211 from rotating counterclockwise and coming out of the limiting slot c1, making the rotary latch 1211 not easy to rotate and achieving the limiting function.

Please referring to FIG. 5, FIG. 6 and FIG. 7, in an alternative embodiment, the sliding assembly 12 may also include a sliding frame 122, the rotary latch 1211 is mounted on the sliding frame 122, and the rotary latch 1211 may also include a rotating shaft k1, a clamping part k2, and an elastic part k3.

The rotating shaft k1 may be fixedly connected to the sliding frame 122, a first end of the clamping part k2 is rotatably connected to the rotating shaft k1, and a second end of the clamping part k2 can be inserted into the limiting slot c1. A first end of the elastic part k3 is connected to a portion between the first end and the second end of the clamping part k2, and a second end of the elastic part k3 is fixedly connected to the sliding frame 122, and the second end of the elastic part k3 is located at one side, close to the ground, of the first end of the elastic part k3.

In an exemplary embodiment, the sliding frame 122 may include a third plate body b3 and two side plates b4 located on both sides of the third plate body b3, the two side plates b4 can be oppositely arranged and both connected to the third plate b3, and a plate surface of the third plate body b3 is perpendicular to a plate surface of any one of the side plates b4. The rotary latch 1211 can be mounted on the third plate body b3. Exemplary, the rotating shaft k1 in the rotary latch 1211 can be fixedly connected to the third plate b3, and one end, away from the clamping part k2, of the elastic part k3 may also be fixedly connected to the third plate body b3.

When the sliding assembly 12 slides along the target direction, the clamping part k2 in the rotary latch 1211 can rotate counterclockwise and disengage from the limit groove c1 to be located outside the limit groove c1. At this time, the elastic part k3 can be in a stretching state to apply a pulling force towards the ground to the clamping part k2, thus preventing the clamping part k2 from continuously rotating counterclockwise. Moreover, when the clamping part k2 moves to the next limiting slot c1 along with the sliding frame 122, the clamping part k2 can be inserted into the limiting slot c1 under the pulling force of the elastic part k3.

Please referring to FIG. 5, FIG. 6 and FIG. 7, in an exemplary embodiment, the locating part 1212 can be arranged on the side plate b4 or arranged on the third plate body b3. Exemplary, the locating part 1212 may include a locating slot c2 formed in the side plate b4, and one side, away from the ground, of the locating slot c2 is provided with an opening. When the clamping part k2 is inserted into the limiting slot c1, the clamping part k2 may also be inserted into the locating slot c2. In this case, the limiting slot c1 and the locating slot c2 are arranged adjacent to each other, a sidewall of the limiting slot c1 and a bottom of the locating slot c2 can apply pressures in opposite directions to the clamping part k2 to clamp the clamping part k2. When the clamping part k2 moves towards the next limiting slot c1 along with the sliding frame 122, the opening in the locating slot c2 can prevent the locating slot c2 from obstructing the clamping part k2 to rotate clockwise, thus preventing a situation that the clamping part k2 cannot be disengaged from the limiting slot c1 and the locating slot c2.

Please referring to FIG. 2, FIG. 3 and FIG. 8, FIG. 8 is a schematic diagram of an exploded structure of a bearing assembly 11 according to an embodiment of the present disclosure. In an alternative embodiment, the bearing assembly 11 may also include a bearing frame 112. The bearing frame 112 includes two opposite first plate bodies b1, and two opposite second plate bodies b2. The two first plate bodies b1 and the two second plate bodies b2 are connected in turn to form an accommodating cavity. The sliding assembly 12 is arranged in the accommodating cavity.

The limiting slot c1 is formed in the first plate body b1, the two first plate bodies b1 and the two second plate bodies b2 are connected in turn to form a quadrilateral frame, which may include a rectangular frame.

Please referring to FIG. 5, FIG. 7 and FIG. 8, two side plates b4 of the sliding frames 122 can be arranged in parallel and adjacent to two first plate bodies b1 of the bearing frame 112, and the third plate body b3 of the sliding frame 122 and one of the second plate bodies b2 of the bearing frame 112 may be arranged in parallel and adjacent to each other.

The sliding frame 122 may slide along a direction perpendicular to the ground in the accommodating cavity of the bearing frame 112. As such, the coupling of the sliding frame 122 and the bearing frame 112 can make the extension and retraction directions of the bearing assembly 11 and the sliding assembly 12 parallel to the target direction all the time.

Please referring to FIG. 3, in the two second plate bodies b2 of the bearing frame 112, the second plate body b2 adjacent to the third plate body b3 in the sliding frame 122 may be provided with two ribs t1. The third plate body b3 can be in contact with the two ribs t1 on the adjacent second plate body b2 to reduce the friction between the adjacent third plate body b3 and the second plate body b2 during relative sliding motion.

Referring to FIG. 7, FIG. 8 and FIG. 9, FIG. 9 is a schematic diagram of another incline device 10 according to an embodiment of the present disclosure. In an alternative embodiment, the rotary latch 1211 may also include a guide part k4, the guide part k4 is fixedly connected to a portion between the first end and the second end of the clamping part k2, that is, the guide part k4 can be fixed to the clamping part k2. Exemplary, the clamping part k2 includes a platy clamping block, and the guide part k4 includes a columnar guide column.

Two ends of the bearing assembly 11 in the target direction may also have a disengagement guide member 113 and a reset guide member 114, respectively, and the disengagement guide member 113 is located at one side, close to the ground, of the reset guide member 114. The disengagement guide member 113 and the reset guide member 114 are both arranged in the accommodating cavity and fixedly connected to the second plate body b2.

The disengagement guide member 113 is configured to drive the guide part k4 and the clamping part k2 to rotate towards a direction away from the limiting slot c1 when the sliding assembly 12 slides towards the ground along the target direction. The reset guide member 114 is configured to drive the guide part k4 and the clamping part k2 to rotate towards a direction close to the limiting slot c1 when the sliding assembly 12 slides away from the ground along the target direction.

As such, when the rotary latch 1211 in the sliding assembly 12 is inserted into a limit slot c1 at the lowest end of the bearing assembly 11, and the sliding assembly 12 continues to slide towards a direction away from the bearing assembly 11, the rotary latch 1211 can be disengaged from the limit slot c1 at the lowest end. At this time, the disengagement guide member 113 can be in contact with the guide part k4, and the clamping part k2 can be driven by the guide part k4 to rotate clockwise towards the direction away from the limiting slot c1. As such, the limiting function of the clamping part k2 can be released, making the sliding assembly 12 and the bearing assembly 11 slide relatively along the target direction. When the sliding assembly 12 slides to a position coinciding with the bearing assembly 11 along the target direction, the reset guide member 114 can be in contact with the guide part k4, and the clamping part k2 can be driven by the guide part k4 to rotate counterclockwise towards the direction close to the limiting slot c1, thus resetting the clamping part k2.

Please referring to FIG. 3, FIG. 8 and FIG. 9, in an alternative embodiment, the disengagement guide member 113 includes a first guide bar 1131, and the reset guide member 114 may include a second guide bar 1141. Each of an extending direction of the first guide bar 1131 and an extending direction of the second guide bar 1141 forms an acute included angle with the target direction, and the ends, away from the ground, of the first guide bar 1131 and the second guide bar 1141 are closer to the limiting slot c1. The guide part k4 moves between the first guide bar 1131 and the second guide bar 1141, that is, the guide part k4 can move between the first guide bar 1131 and the second guide bar 1141.

Exemplary, the target direction includes a first direction and a second direction. The first direction is a direction pointing to the ground, and the second direction is a direction away from the ground. When the rotary latch 1211 in the sliding assembly 12 is inserted into the limiting slot c1 at the lowest end of the bearing assembly 11, and the sliding assembly 12 continues to slide along the first direction, the rotary latch 1211 can be disengaged from the limiting slot c1 at the lowest end. In this case, as shown in FIG. 9, the guide part k4 in the rotary latch 1211 can be in contact with one side, away from the ground, of the first guide bar 1131. Moreover, when the sliding assembly 12 continues to slide along the first direction, the guide part k4 can move along an extending direction of the first guide bar 1131 and drive the clamping part k2 to rotate clockwise towards a direction away from the limiting slot c1. When the guide part k4 moves to one end, away from the limiting slot c1, of the first guide bar 1131, the sliding assembly 12 stops sliding, in this case, the clamping part k2 rotates to one side, away from the limiting slot c1, of the rotating shaft k1, and the clamping part k2 can be kept at a current posture under the action of the elastic part k3. As such, the limiting effect of the clamping part k2 can be released, making the sliding assembly 12 and the bearing assembly 11 relatively move along the second direction. When the sliding assembly 12 moves to a position which is about to coincide with the bearing assembly 11 along the second direction, the guide part k4 in the rotary latch 1211 can be in contact with one side, facing the ground, of the second guide bar 1141. Moreover, when the sliding assembly 12 continues to slide along the first direction, the guide part k4 can move along the extending direction of the second guide bar 1141 and drive the clamping part k2 to rotate counterclockwise towards a direction close to the limiting slot c1. When the guide part k4 moves to one end, close to the limiting slot c1, of the second guide bar 1141, the sliding assembly 12 stops sliding, in this case, the clamping part k2 rotates to one side, close to the limiting slot c1, of the rotating shaft k1, and the clamping part k2 can be disposed in the locating slot c2, and kept at a current posture under the action of the elastic part k3, that is, the clamping part k2 is in a reset state.

In an alternative embodiment, the guide part k4 may be connected to one end of the elastic part k3 to simplify a structure of the rotary latch 1211.

Referring to FIG. 7 and FIG. 8, in an exemplary embodiment, one end, away from the ground, of the first plate body b1 of the bearing frame 112 is provided with an accommodating groove c3, the accommodating groove c3 and the multiple limiting slots c1 can be arranged along a target direction, and one side, away from the ground, of the accommodating groove c3 is provided with an opening. When the clamping part k2 is in the reset state, the accommodating groove c3 and the locating slot c2 can be arranged adjacent to each other, and the clamping part k2 can be simultaneously located in the locating slot c2 and the accommodating groove c3.

Please referring to FIG. 7 and FIG. 8, in an alternative embodiment, one end, close to the ground, of the bearing assembly 11 may be provided with a third stopper 115, and one end, away from the ground, of the sliding assembly 12 may be provided with a fourth stopper 123. When one end, away from the ground, of the sliding assembly 12 slides to a position where one end, close to the ground, of the bearing assembly 11 is located, the third stopper 115 is abutted against the fourth stopper 123. The third stopper 115 may be fixedly connected to one end, close to the ground, of the bearing frame 112. The fourth stopper 123 may be fixedly connected to one end, away from the ground, of the sliding frame 122. As such, it is possible to prevent the bearing assembly 11 and the sliding assembly 12 from disengaging from each other during sliding along the target direction.

Please referring to FIG. 10, FIG. 10 is a schematic diagram of another incline device 10 according to an embodiment of the present disclosure. In an alternative embodiment, the incline device 10 may also include a position sensor 13, or multiple position sensors 13. The multiple position sensors 13 are in one-to-one correspondence with the multiple limiting slots c1, and located outside the corresponding limiting slots c1. The position sensor 13 is configured to detect whether the rotary latch 1211 is inserted into the corresponding limiting slot c1 or not. The position sensor 13 may include a micro switch which may be configured to detect a position of an object. When the object moves to a position of the micro switch, the micro switch will convert the change of the position of the object into the action of a contact through a mechanical mechanism, thus sending out a position detection signal.

Exemplary, the incline device 10 further includes a controller and a display device. The bearing assembly 11 is provided with a first limiting slot and a second limiting slot arranged along a direction away from the ground. The multiple position sensors 13 include a first sensor and a second sensor. When the rotary latch 1211 is clamped into the first limiting slot, the first position sensor 13 can transmit a first position detection signal to the controller, the controller, after receiving the first position detection signal, can control the display device to display corresponding text information or picture information, where the text information or picture information can be used for describing a current inclination angle of the treadmill. Therefore, it is convenient for the user to check the current inclination of the treadmill and improve the user experience.

Referring to FIG. 1, in an alternative embodiment, the incline device 10 may also include a supporting base 14 and a mounting support 15. The supporting base 14 is fixedly connected to the sliding assembly 12, and the mounting support 15 is fixedly connected to the bearing assembly 11 and the running platform support. The supporting base 14 is provided with a handle part, and it is convenient for the user to drive the sliding assembly 12 to slide relative to the bearing assembly 11 through the handle part.

The present disclosure further provides a treadmill. The treadmill may include an incline device 10, a running belt, a running platform support, a motor, and a roller assembly. The incline device 10 may be the incline device 10 in any above embodiment.

The number of the bearing assemblies 11 and the number of the sliding assemblies 12 in the incline device 10 may be two, and two bearing assemblies 11 and the two sliding assemblies 12 are in one-to-one sliding connection. The two bearing assemblies 11 can be located on both sides of the running platform support, respectively, and the two sliding assemblies 12 can also be located on both sides of the running platform support, respectively, thus making the incline device 10 have good symmetry and improving the aesthetics and stability of the incline device 10.

In an exemplary embodiment, an adjusting process of the incline device 10 in the treadmill may include the following five steps:

• • (1) Before the user uses the treadmill, the treadmill is in a horizontal state, and the user can drive the sliding assembly 12 to slide relative to the bearing assembly 11 through the handle part on the supporting base 14. When the rotary latch 1211 in the sliding assembly 12 is inserted into the second limiting slot c1 in the bearing assembly 11, the sliding assembly 12 stops moving, thus keeping the incline device 10 at a current height, that is, the inclination angle of the treadmill is kept at the current slope.
  • (2) The controller is configured to detect the position of the rotary latch 1211 through the position sensor 13, thus controlling the display device to display that the current slope of the treadmill is the first slope.
  • (3) The user drives the sliding assembly 12 to slide relative to the bearing assembly 11 again through the handle part on the supporting base 14. When the rotary latch 1211 in the sliding assembly 12 is inserted into the first limiting slot c1 in the bearing assembly 11, the sliding assembly 12 stops moving, thus keeping the incline device 10 at the current height. As such, inclination angle of the treadmill can be lifted, and the treadmill can be kept at the current slope.
  • (4) The controller is configured to detect the position of the rotary latch 1211 through the position sensor 13, thus controlling the display device to display that the current slope of the walking machine is the second slope.
  • (5) The user drives the sliding assembly 12 to slide again relative to the bearing assembly 11 through the handle part on the supporting base 14. When the rotary latch 1211 in the sliding assembly 12 is disengaged from the first limiting slot c1 in the bearing assembly 11 and rotates clockwise under the driving of the disengagement guide member 113, the sliding assembly 12 slides again relative to the bearing assembly 11 until the rotary latch 1211 rotates counterclockwise into the locating slot c2 under the driving of the reset guide member 114, the sliding assembly 12 and the load-bearing assembly 11 coincide in position, and in this case, the treadmill returns to a horizontal state.

It should be noted that dimensions may be exaggerated for clarity of illustration. It may be understood that when an element is referred to as being “on” another element, it can be directly on the other element or layer, or an intervening element may be present. In addition, it may be understood that when an element is referred to as being “under” another element, it can be directly under the other element or layer, or more than one intervening element may be present. In addition, it may also be understood that when an element is referred to as being “between” two elements, it can be the only layer between two elements, or more than one intervening element may be present. Like reference numerals refer to like elements throughout.

In the present disclosure, the terms “first”, “second”, “third” and “fourth” are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. Terms “a plurality of” means two or more, unless otherwise specifically defined.

The above is only the preferred embodiment of the present disclosure, and is not used to limit the present disclosure. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present disclosure should be included in the scope of protection of the present disclosure.
