DETAILED DESCRIPTION OF EMBODIMENTS

The present disclosure will be described in further detail below in conjunction with the accompanying drawings and the specific embodiments. The advantages and features of the present disclosure will become more apparent from the following description. It is to be noted that the accompanying drawings in a quite simplified form with an inaccurate ratio are merely used to assist in describing the objectives of the embodiments of the present disclosure conveniently and clearly.

Referring to FIG. 1 and FIG. 2, the present embodiment provides a treadmill deck motor mounting structure, which is mounted on the side of a treadmill adjacent to a front roller 200 and is configured to provide a driving force to the front roller 200. The treadmill includes a support frame body 100. The support frame body 100 is a rectangular frame and includes two support tubes 110 arranged in parallel. A plurality of support bars 120 are arranged along a length direction of the support tubes 110, and two ends of each support bar 120 are fixedly connected to the support tubes 110 on corresponding sides, thereby enhancing the structural strength of the support frame body. A connecting portion 111 is provided on an upper surface of each support tube 110.

A front roller 200 is mounted at a front end of the support frame body 100. One side of the front roller 200 is connected to a motor 600 which provides a driving force. A rear roller 300, parallel to the front roller 200, is mounted at a rear end of the support frame body 100. A treadmill belt 400 is connected to the front roller 200 and the rear roller 300. As the front roller 200 and the rear roller 300 rotate, the treadmill belt 400 is driven in a unidirectional manner. The treadmill belt 400 is an elongated hollow annular structure, and a treadmill deck 500 is disposed inside the hollow annular structure. The treadmill belt 400 is wrapped around the support frame body 100 to form a moving contact surface on an upper side of the support frame body 100. An output shaft of the motor 600 is connected to the front roller 200 to drive the rotation of the front roller 200, so that the front roller 200 drives the treadmill belt 400 to move on the moving contact surface.

Specifically, the two support tubes 110 on both sides have different lengths. A front end surface of the support tube 110 on one side is spaced apart from the front roller 200, defining a space for accommodating a motor mounting housing 700. The motor mounting housing 700 is mounted in the space and welded and fixed to the support tube 110 on the side. This configuration not only enables a more compact overall structure and reduces the overall size, but also shortens a motion transmission distance and improves transmission efficiency.

The support tube 110 is a square hollow tube, which ensures strength while reducing the weight, thereby decreasing the overall weight of a machine. A protective cover 112 is connected to a rear end of each support tube 110. At least one cushion block 113 is provided on a lower side of each support tube 110 for anti-slip and sound insulation purposes. Preferably, the cushion block 113 is disposed near a rear portion of the support tube 110. The cushion block 113 has slight elasticity and may be made of a rubber, silicone, or PVC material to provide better shock absorption and cushioning performance. To further improve the friction resistance of the cushion block 113, micro-protrusion particles are formed on a bottom of the cushion block 113 to enhance a frictional force when in contact with the ground.

Embodiment 1

• • Referring to FIG. 3a to FIG. 3f, the motor mounting housing 700 has an elongated mounting cavity 710, and a top of the elongated mounting cavity 710 is an opening structure for accommodating the motor 600 and a belt pulley 800 coaxially connected to the front roller 200. One end of the front roller 200 is connected to the motor mounting housing 700. The output shaft of the motor 600 is connected to the belt pulley 800 via a belt 810 to achieve power transmission. The motor 600 is characterized by a miniature size and can be flexibly disposed within the mounting cavity 710 of the motor mounting housing without requiring additional space for motor placement, effectively saving space.

To avoid interference between the front roller 200 and the motor mounting housing 700, a semi-circular recess with an upward opening is formed on a sidewall of the motor mounting housing 700 on the side adjacent to the front roller 200. The radius of the recess is greater than the radius of the front roller 200, allowing the front roller 200 to extend into the mounting cavity 710, such that the belt pulley 800 connected thereto is positioned within the mounting cavity 710. By providing the belt pulley 800 and the motor 600 within the mounting cavity 710, the integrity of a transmission structure is improved, and installation and subsequent maintenance are facilitated.

In the embodiment of the present disclosure, a first mounting opening 510 for accommodating the motor 600 is formed on the side of the treadmill deck 500 adjacent to the motor 600; when installed, the motor 600 is embedded in the first mounting opening 510, and an outer surface of the motor mounting housing 700 and an outer surface of the support tube 110 on the same side lie in the same plane, thereby reducing the distance in a width direction and further decreasing the overall size of the machine.

The motor mounting housing 700 is provided with lug plates 720 that extend horizontally toward the treadmill deck 500. The lug plates 720 are fixedly connected to the treadmill deck 500 via screws, or by welding or riveting.

Embodiment 2

• • Referring to FIG. 4a to FIG. 4g, the structure and installation position of the motor mounting housing 700 are consistent with those in Embodiment 1. The volume of the mounting cavity 710 is greater than the volume of the motor 600, so that the entire motor 600 is accommodated within the mounting cavity 710. The mounting cavity 710 has a first sidewall 711 and a second sidewall 712 arranged parallel to the first sidewall 711, and the first sidewall 711 is arranged adjacent to the treadmill deck 500. The output shaft of the motor 600 passes through the second sidewall 712 of the motor mounting housing 700. A belt pulley 800 is coaxially connected to the front roller 200, and an end of the front roller 200 passes through the second sidewall 712 of the motor mounting housing. The belt pulley 800 disposed within the mounting cavity 710. The belt pulley 800 is connected to the output shaft of the motor 600 via a belt 810. An arc-shaped recess with an upward opening is formed on an upper surface of the first sidewall 711 of the motor mounting housing, facilitating the entry of the front roller 200 into the mounting cavity 710.

A first slot 731 corresponding to the position of the belt pulley 800 and a second slot 732 corresponding to the position of the motor 600 are formed in a bottom 730 of the motor mounting housing 700, which facilitates heat dissipation during operation of the belt pulley and the motor and avoids heat accumulation that could affect performance, thereby extending the service life.

A first mounting opening 510 is formed on an end surface of the treadmill deck 500 on the side adjacent to the motor mounting housing 700 to reserve a space for the installation of the motor mounting housing 700. The first mounting opening 510 is formed on the end surface, facilitating control of the size of the first mounting opening 510 to avoid excessive cutting, thereby reducing waste of plate materials.

A horizontal bend 7111 is formed at a top end of the first sidewall 711 of the motor mounting housing, and the horizontal bend 7111 is fitted against a bottom surface of the treadmill deck 500 and fixed to the treadmill deck 500 via screws. Since the motor mounting housing 700 has a relatively large width and is fixedly connected only to an end surface of the shorter support tube 110, the stability thereof may be adversely affected. In particular, vibration may occur during the operation of the motor 600. Therefore, an additional connection point is provided to improve the mounting stability of the motor mounting housing 700.

Embodiment 3

• • Referring to FIG. 5a to FIG. 5f, the structure and installation position of the motor mounting housing 700 are consistent with those in Embodiment 2. A belt pulley 800 is located on an outer side of the first sidewall 711 facing the treadmill deck 500, and one end of the front roller 200 is connected to the first sidewall 711 of the motor mounting housing. The belt pulley 800 is mounted on an outer periphery of the front roller 200, and then the motor 600 and the belt pulley 800 are connected via a belt 810. This configuration facilitates the separate installation of the components and then the connection, thereby reducing the mounting difficulty of the belt pulley 800. Additionally, the belt pulley 800 is located outside the mounting cavity 710, which facilitates the adjustment of the spacing between the belt pulley 800 and the mounting cavity 710, thereby reducing the likelihood of interference. The motor 600 is characterized by a miniature size and can be flexibly disposed within the mounting cavity 710 of the motor mounting housing without requiring additional space for motor placement, effectively saving space.

Furthermore, the second sidewall 712 of the motor mounting housing is a detachable welded component. After the motor 600 is installed, the second sidewall 712 is welded and fixed to a corresponding peripheral wall of the motor mounting housing. This configuration facilitates the installation of the motor 600 and facilitates the adjustment of the installation position of the motor 600 as there is no obstruction of the second sidewall 712. During the installation process, workers can change the operation angle, reducing the mounting difficulty of the motor 600 and improving the mounting efficiency.

An arc-shaped recess with an upward opening is formed on an upper surface of the first sidewall 711 of the motor mounting housing. An outer peripheral edge of the motor 600 on the side adjacent to the output shaft is embedded in the arc-shaped recess, defining a mounting space of the motor 600. After the motor 600 is started, this configuration helps to reduce self-induced vibration and lowers the probability of noise generation.

According to the embodiment of the present disclosure, the treadmill deck motor mounting structure also comprises a controller 900. The controller 900 is designed in a right-angle shape. A horizontal section is parallel to the treadmill deck 500, and a clamping groove 910 is integrally formed on a vertical section, which improves the fixing accuracy of the controller 900 and the support tube 110.

Two first mounting openings 510 symmetrically arranged are formed on an end surface of the treadmill deck 500 adjacent to the motor 600, i.e., an outer contour line of the treadmill deck 500 is in an inverted-T shape, and the two first mounting openings 510 are arranged in left-right symmetry with respect to a center line of the treadmill deck 500 in a length direction, where “left” and “right” are defined based on the user-facing direction. One of the first mounting openings 510 is configured to accommodate the controller 900, and the other first mounting opening 510 can enlarge the mounting space for the belt 810 and the output shaft of the motor 600, thereby improving installation convenience. The first mounting openings 510 are formed on the end surface, facilitating control of the size of the first mounting openings 510 to avoid excessive cutting, thereby reducing waste of plate materials.

Embodiment 4

• • Referring to FIG. 6a to FIG. 6g, the structure of the motor mounting housing 700 is consistent with that in Embodiment 2. A motor 600 and a dual-pulley transmission structure connected thereto are mounted in the mounting cavity 710. The dual-pulley transmission structure is connected to the front roller 200 to achieve motion transmission. By providing the dual-pulley transmission structure, the power output from the motor 600 is gradually transmitted to the front roller 200, thereby improving the transmission stability. The output shaft of the motor 600 is located inside the mounting cavity 710 and on the side away from the treadmill deck 500.

The dual-pulley transmission structure includes a pulley set 1000 connected to the motor 600 via a pulley set belt 1100, and a belt pulley 800 coaxially connected to the front roller 200. The pulley set 1000 and the belt pulley 800 are connected via a belt 810. A rotating shaft of the belt pulley 800 is connected to the motor mounting housing 700. The pulley set 1000 includes a driving pulley A and a driven pulley B coaxially arranged, where the diameter of the driving pulley A is greater than that of the driven pulley B. The output shaft of the motor 600 is connected to the driving pulley A via the pulley set belt 1100, and the driven pulley B is connected to the belt pulley 800 via the belt 810 to achieve transmission.

A first opening 520 and a second opening 530 are formed at an end surface of the treadmill deck 500 on the side adjacent to the motor mounting housing 700, forming a step shape. A motor body of the motor 600 is embedded in the first opening 520, and an input shaft is embedded in the mounting cavity 710 of the motor mounting housing. The second opening 530 serves as a reserved space for the installation of the motor mounting housing 700, allowing an outer edge of the motor mounting housing 700 and an outer edge of the treadmill deck 500 to lie in the same plane, thereby not only saving the mounting space, but also controlling the overall size, thereby reducing transportation costs.

Embodiment 5

• • Referring to FIG. 7 a to FIG. 7 g, based on Embodiment 4, the motor 600 and the dual-pulley transmission structure are entirely mounted inside the motor mounting housing 700. An elongated second mounting opening 540 is formed on an end surface of the treadmill deck 500 on the side adjacent to the motor mounting housing 700. The second mounting opening 540 is configured to accommodate the motor mounting housing 700, eliminating the need to form a plurality of openings for accommodating the individual components and thereby improving processing efficiency. The length of the second mounting opening 540 matches that of the motor mounting housing 700, providing a reserved space for the installation of the motor mounting housing 700.

The above description is merely a description of the preferred embodiments of the present disclosure, and does not limit the scope of the present disclosure. Any changes or modifications made by those of ordinary skill in the field of the present disclosure based on the above-disclosed content shall fall within the scope of protection of the claims.
