It should be noted here that the description of these embodiments is intended to assist in understanding of the present disclosure, but does not constitute a limitation of the present disclosure. Furthermore, the technical features involved in the embodiments of the present disclosure described below may be combined with each other as long as they do not conflict with each other.

FIGS. 1 to 12 show an example of a foldable canopy. Referring to FIGS. 1 to 12, the foldable canopy has an unfolded position and a folded position, and includes a foldable canopy frame body 2; the canopy frame body 2 can be independently supported on the ground, and the canopy frame body 2 is covered with a cloth cover (not shown) for blocking the sun, sheltering from wind and rain, or the like; a part (for example, an edge part) of the cloth cover, which is called surrounding cloth, can hang down to a side of the canopy frame body 2. As shown in FIGS. 1 and 3 to 5, the canopy frame body 2 includes a plurality of legs 1 extending in an up-down direction and a top frame connected to upper portions of the legs 1, and is supported on the ground by the legs 1, and the cloth cover mainly covers on the top frame. The canopy further includes an overhanging rod 3 having an inner end portion and an outer end portion, and the inner end portion of the overhanging rod 3 is rotatably connected to the leg 1, particularly by a pivot. A plurality of overhanging rods 3 are provided, and a number and positions of the overhanging rods are in one-to-one correspondence with a number and positions of the legs 1; that is, the inner end portion of each overhanging rod 3 is rotatably connected to one corresponding leg 1, and the surrounding cloth is connected to the outer end portions of the overhanging rods 3, can be spread out by the overhanging rods 3 to increase a sunshade area as an eave, and can also hang down to the side of the canopy along with folding of the overhanging rods 3 to be used as side surrounding cloth. Each overhanging rod 3 has a folded state and an unfolded state, and the outer end portion of the overhanging rod 3 is drawn close to the leg 1 in the folded state and is offset from the leg 1 in the unfolded state. That is, the overhanging rod 3 has a folded state in which the overhanging rod is drawn close to the leg 1 and an unfolded state in which the overhanging rod is unfolded relative to the leg 1. After the overhanging rod 3 is unfolded, the surrounding cloth is extended outwards, such that the sunshade area of the canopy can be increased. Further, the overhanging rod 3 on the left side extends leftwards in the unfolded state; that is, the outer end portion of the overhanging rod 3 is located on the left side of the leg 1. The overhanging rod 3 on the right side extends rightwards in the unfolded state; that is, the outer end portion of the overhanging rod 3 is located on the right side of the leg 1. Therefore, the surrounding clothes on the left side and the right side can be unfolded, eave areas on the left side and the right side of the canopy are increased, and the sunshade areas on the left side and the right side are increased. When the overhanging rod 3 is in the folded state, the surrounding cloth hangs down and is located on the side of the canopy.

The top frame includes a plurality of foldable eave frames 21, and the eave frames 21 are connected between adjacent legs 1. The canopy further includes a plurality of cross rods 4, and a number and positions of the plural cross rods 4 are in one-to-one correspondence with the number and the positions of the plural overhanging rods 3. As shown in FIGS. 7 to 12, each cross rod 4 has a first end portion rotatably connected to the overhanging rod 3 and a second end portion for being detachably connected with one of the eave frames 21. The second end portion of the cross rod 4 is disconnected from the eave frame 21 when the overhanging rod 3 is in the folded state, and the second end portion of the cross rod 4 is connected with the eave frame 21 when the overhanging rod 3 is in the unfolded state. During folding the canopy frame body 2 from an unfolded position to a folded position, the second end portion of the cross rod 4 is disconnected from the eave frame 21, and the overhanging rod 3 is converted from the unfolded state to the folded state. The second end portion of the cross rod 4 is detachably connected with a rod piece of the eave frame 21 and configured to be automatically disconnected from the eave frame 21 by a force from the overhanging rod 3 when the eave frame 21 is folded, an implementation of which is described in detail below.

It should also be noted that in the present embodiment, the overhanging rod 3 is directly and rotatably connected to the leg 1 by the pivot; in some other embodiments, the overhanging rod 3 can be indirectly and rotatably connected to the leg 1 by other components, such as a sliding sleeve, a connecting cap, or the like, on the leg 1.

The eave frame 21 includes a connecting rod 211 which can be rotated downwards when the canopy frame body 2 is folded; the second end portion of the cross rod 4 is provided with a clamping groove portion 41 capable of being clamped on the connecting rod 211, and the clamping groove portion 41 has a downwards facing notch 410, as shown in FIG. 12. A clamping groove formed by the clamping groove portion 41 extends upwards from a lower surface of the clamping groove portion 41, and a profile of the clamping groove is approximately in an inverted U shape in a cross section of the clamping groove portion 41 perpendicular to a length direction of the connecting rod 211. When the canopy frame body 2 is folded, the connecting rod 211 may be rotated downwards to be disconnected from the clamping groove of the clamping groove portion 41, and the cross rod 4 and the eave frame 21 are disconnected, thus avoiding that since the overhanging rod 3 is forgotten to be folded, the canopy frame body 2 cannot be folded, or the overhanging rod 3 and the rod piece of the canopy frame body 2 are damaged. In the present embodiment, the overhanging rods 3 are not unfolded in a diagonal direction of the canopy; as shown in FIGS. 3 and 4, each of the overhanging rods 3 extends in a length direction of a first eave frame 21 (for example, the eave frame located on the front side); that is, the overhanging rod 3 extends in substantially the same direction as the first eave frame 21 in a top view. The cross rod 4 connected with the overhanging rod 3 is detachably connected with a second eave frame 21, and the second eave frame 21 intersects with the above-mentioned first eave frame 21, for example, the eave frame located on the left side.

As shown in FIGS. 10b to 12, a positioning protrusion 211a is formed on the connecting rod 211 fitted with the cross rod 4, and a positioning groove 411 fitted with the positioning protrusion 211a is provided in the clamping groove portion 41 to restrict sliding of the clamping groove portion 41 in the length direction of the connecting rod 211. The positioning groove 411 is communicated with the clamping groove formed by the clamping groove portion 41 and extends upwards from the lower surface of the clamping groove portion 41, and the positioning protrusion 211a enters the positioning groove 411 when the clamping groove portion 41 is clamped on the connecting rod 211; the positioning groove 411 has two opposite limiting walls, the limiting walls as a whole are not parallel to the length direction of the connecting rod 211, and the positioning protrusion 211a is located between the two limiting walls to prevent the clamping groove portion 41 from moving back and forth on the connecting rod 211. The positioning protrusion 211a specifically includes a pin, a pop-rivet, or a rivet fixed on the connecting rod 211; still further, the positioning protrusion 211a is located at a pivot position of the connecting rod 211 and another rod piece (another rod piece of the eave frame), and may be a part of or provided on the pivot for pivoting the connecting rod 211 and the other rod piece. In the present embodiment, each cross rod 4 is a single rod; while in some other embodiments, the cross rod 4 may be formed by a plurality of rod pieces.

The canopy further includes a plurality of support rods 5 with first end portions and second end portions, and a number and positions of the plurality of support rods 5 are in one-to-one correspondence with the number and the positions of the plurality of overhanging rods 3.

After the top cap 231 and the bottom cap 232 are locked, the canopy frame body 2 is locked in the unfolded position by the central locking mechanism 23; when the top cap 231 and the bottom cap 232 are unlocked, the inclined rod 224 moves downwards along with the sliding sleeve 101, and pulls the top rod unit 22 to be folded; that is, the outer top rod 221 and the inner top rod 222 rotate downwards, such that the inner end portion of the outer top rod 221 and the outer end portion of the inner top rod 222 are drawn close to the lower end portion of the leg 1, the top cap 231 and the upper end portion of the leg 1 are drawn close to each other, and the lower end portion of the auxiliary top rod 223, the bottom cap 232 and the outer end portion of the inner top rod 222 are drawn close to each other.

The canopy frame body 2 further includes a reinforcing mechanism 6 connected between one of the eave frames 21 and the central locking mechanism 23. Specifically, the reinforcing mechanism 6 includes an outer reinforcing rod 621 and an inner reinforcing rod 622, one end portion of the outer reinforcing rod is rotatably connected with one end portion of the inner reinforcing rod, the other end portion of the outer reinforcing rod 621 is rotatably connected to the eave frame, and the other end portion of the inner reinforcing rod 622 is rotatably connected to the central locking mechanism 23, specifically, the top cap 231. The reinforcing mechanism 6 further includes an auxiliary reinforcing rod 623, one end portion of the auxiliary reinforcing rod 623 is rotatably connected to the inner reinforcing rod 622, and the other end portion is rotatably connected to the bottom cap 232. In the present embodiment, the other end portion of the outer reinforcing rod 621 is rotatably connected to a cross connection position of the middle connecting rod assembly 210. Specifically, the other end portion of the outer reinforcing rod 621 is rotatably connected to a connecting piece 624 by a fourth pivot 621a, the connecting piece 624 is fixedly connected to the third pivot 212, and an axis of the fourth pivot 621a and an axis of the third pivot 212 form an included angle greater than zero and less than 180 degrees, and are perpendicular to each other. The canopy according to the present embodiment has two reinforcing mechanisms 6 provided on left and right sides of the top frame respectively.

A using method of the canopy includes: unfolding the canopy frame body 2, locking the top cap 231 and the bottom cap 232 to each other after unfolding to stably unfold the canopy, as shown in FIG. 1, and unfolding the overhanging rods 3 on one side as required, as shown in FIG. 3; or unfolding the overhanging rods 3 on both sides, as shown in FIGS. 4 and 5. A specific process of unfolding the overhanging rod 3 is as follows: the overhanging rod 3 is lifted, the support base 51 moves upwards therewith, the second end portion of the cross rod 4 is clamped to the positioning protrusion 211a on the connecting rod 211, and the overhanging locking mechanism is locked to enable the overhanging rod 3 to be stably in the unfolded state. A specific process of folding the overhanging rod 3 is as follows: the overhanging locking mechanism is unlocked, the second end portion of the cross rod 4 is disconnected from the connecting rod 211, the support base 51 slides downwards under the action of the gravity, and the overhanging rod 3 and the cross rod 4 automatically drop to the side of the leg body 10. When the canopy is required to be folded, the overhanging rod 3 can be folded in advance; if the overhanging rod is forgotten to be folded, in the process of folding the canopy frame body 2, the cross rod 4 can be automatically disconnected from the connecting rod 211 and released under the pressing action of an external force, and the process is specifically as follows: the top cap 231 and the bottom cap 232 are unlocked, the sliding sleeve 101 on the leg body 10 moves downwards, the connecting rods 211 of the eave frame 21 rotate to approach each other, and especially, the connecting rod 211 connected with the cross rod 4 rotates downwards to be disconnected from the notch 410 on the clamping groove portion 41, and the canopy frame body 2 is normally folded.

After the canopy is unfolded, the overhanging rod 3 can be flexibly unfolded or folded as desired, and the overhanging rod can be quickly and conveniently unfolded and folded; the cross rod 4 can reinforce the overhanging rod 3 after the overhanging rod 3 is unfolded, and good strength is realized; particularly, when the canopy is folded, if the overhanging rod 3 is forgotten to be folded, the second end portion of the cross rod 4 can be automatically disconnected from the connecting rod 211 of the eave frame 21 under the action of the external force along with the folding of the eave frame 21, thus avoiding accident breaking of the overhanging rod 3 or damage to the structure of the canopy frame body 2 caused when the overhanging rod 3 is forgotten to be folded. Furthermore, the foldable reinforcing mechanism 6 is provided between the eave frame 21 and the central locking mechanism 23, such that when the canopy frame body 2 is unfolded and folded, a pushing force applied by the cross rod 4 to the eave frame 21 can be counteracted or reduced, thus avoiding the problem that the eave frame 21 is recessed and deformed due to the pushing force of the cross rod 4. The canopy frame body 2 is locked by the central locking mechanism 23 and can be quickly unfolded and folded.

FIGS. 14 to 16 show another example of the foldable canopy which differs from the above foldable canopy only in the reinforcing mechanism 6. Referring to FIGS. 14 to 16, the reinforcing mechanism 6 in the present embodiment is connected between the eave frames 21 and the top rod units 22. The reinforcing mechanism 6 includes a reinforcing rod 610, one end portion of the reinforcing rod 610 is rotatably connected to the inner top rod 222, and the other end portion is rotatably connected to the eave frame 21 (specifically, an upper rotary connection position of two adjacent connecting rod assemblies 210). Specifically, one end portion of the reinforcing rod 610 is pivotally connected to the inner top rod 222, and a distance between the connection position of the two and the inner end portion of the inner top rod 222 is less than one third of a length of the inner top rod 222; the other end portion of the reinforcing rod 610 is pivotally connected to a connector 611, and the connecting rods 211 of the two adjacent connecting rod assemblies 210 are rotatably connected by the connector 611. The canopy according to the present embodiment has eight reinforcing rods 610, each eave frame 21 is rotatably connected to the inner top rods 222 of two adjacent top rod units 22 by two reinforcing rods 610, and four groups of eave frames 21 and top rod units 22 are connected to form a reinforcing structure, so as to solve the problem that the eave frames 21 are recessed and deformed due to the pushing forces of the cross rods 4. The reinforcing rods 610 can rotate along with the unfolding and folding of the canopy frame body 2 without affecting the unfolding and folding of the canopy frame body 2.

FIG. 14 shows a canopy with surrounding clothes 70. The two overhanging rods 3 on the left side are unfolded, such that the surrounding cloth 70 on the left side is unfolded to increase a shading area; and the two overhanging rods 3 on the right side are not unfolded, and the surrounding cloth 70 on the right side hangs on the right side of the canopy, and is specifically located on the right sides of the two legs 1 on the right side. Further, a connection position of the cross rod 4 and the eave frame 21 is lower than the surrounding cloth 70.

FIGS. 17 to 19 show still another example of the foldable canopy which differs from the foldable canopy shown in FIGS. 1 to 12 only in that a connection mode of the overhanging rod 3 and the canopy frame body is different. As shown in FIGS. 17 to 19, the overhanging rod 3 is detachably inserted to the leg 1, instead of being rotatably connected with the leg 1. Specifically, the inner end portion of the overhanging rod 3 is detachably inserted to the leg 1 by the sliding sleeve 101 on the leg 1. The sliding sleeve 101 is provided with a slot 101a, and the slot 101a extends substantially obliquely. When the overhanging rod 3 is in the unfolded state, the inner end portion of the overhanging rod 3 is inserted into the slot 101a to be connected with the leg 1; when the overhanging rod 3 is in the folded state, the inner end portion of the overhanging rod 3 is pulled out of the slot 101a to be separated from the leg 1. The cross rod 4 can also be automatically disconnected from the connecting rod 211 of the eave frame 21 when the canopy frame body is folded.

FIGS. 20 and 21 show a fourth example of the foldable canopy which differs from the foldable canopy shown in FIGS. 1 to 12 only in that the connection mode of the overhanging rod 3 and the canopy frame body is different. As shown in FIGS. 20 and 21, the overhanging rod 3 is detachably inserted to the leg 1, instead of being rotatably connected with the leg 1. Specifically, the inner end portion of the overhanging rod 3 is detachably inserted to the fixed joint 11 of the leg 1. The fixed joint 11 is provided with a slot 11a, and the slot 11a extends substantially obliquely. When the overhanging rod 3 is in the unfolded state, the inner end portion of the overhanging rod 3 is inserted into the slot 11a to be connected with the leg 1; when the overhanging rod 3 is in the folded state, the inner end portion of the overhanging rod 3 is pulled out of the slot 11a to be separated from the leg 1. The cross rod 4 can also be automatically disconnected from the connecting rod 211 of the eave frame 21 when the canopy frame body is folded.

FIGS. 22 to 24 show a fifth example of the foldable canopy which differs from the foldable canopy shown in FIGS. 1 to 12 only in that a connection mode of the overhanging rod 3, the cross rod 4 and the support rod 5 is different. Specifically, as shown in FIGS. 22 to 24, the fixed base 30 on the overhanging rod 3 is rotatably connected with a rotating base 31, the first end portion of the cross rod 4 is rotatably connected with the rotating base 31 by a pivot a1, and the second end portion of the support rod 5 is rotatably connected with the fixed base 30 by a pivot a2. Further, the rotating base 31, the fixed base 30 and the second end portion of the support rod 5 are rotatably connected by the pivot a2.

FIGS. 25 to 27 show a sixth example of the foldable canopy which differs from the foldable canopy shown in FIGS. 1 to 12 only in that the connection mode of the overhanging rod 3, the cross rod 4 and the support rod 5 is different. Specifically, as shown in FIGS. 25 to 27, the first end portion of the cross rod 4 is rotatably connected to the fixed base 30 on the overhanging rod 3 by a universal rotating joint 32, and the second end portion of the support rod 5 is rotatably connected to the fixed base 30 by a pivot a3.

In any of the three connection modes described above, the lower end portion of the overhanging rod 3, the second end portion of the cross rod 4, the first end portion of the support rod 5 and the leg 1 are drawn close to each other when the overhanging rod 3 is in the folded state.
