Referring to fig. 1, a folding structure 100 is provided in the present embodiment. The folding structure 100 includes: the first connecting portion 110, the second connecting portion 120, the limiting member 130 and the rotating shaft 140.

As shown in fig. 2, in the present embodiment, the first connection portion 110 includes a top wall 111, and two first sidewalls 112 integrally formed with both ends of the top wall 111, respectively. The top wall 111 and the two first side walls 112 enclose a mounting slot. The second connecting portion 120 includes a bottom wall 121 and two second sidewalls 122 integrally formed with two ends of the bottom wall 121. The bottom wall 121 and the two second side walls 122 enclose a recess. The second connection portion 120 is inserted into a mounting groove defined by the top wall 111 and the two first side walls 112.

The second connecting portion 120 is rotatably connected to the first connecting portion 110 by a rotating shaft 140. The second connecting portion 120 has an opened state and a folded state. The second connecting portion 120 can be switched between the opened state and the folded state by rotating about the rotating shaft 140 with respect to the first connecting portion 110.

Specifically, the rotating shaft 140 is respectively engaged with corresponding holes on the two first side walls 112 and the two second side walls 222, so that the second connecting portion 120 is rotatably connected with the first connecting portion 110.

The limiting member 130 is connected to the first connecting portion 110. The limiting member 130 has a first position and a second position.

Specifically, as shown in fig. 1 and 2, the first sidewall 112 of the first connecting portion 110 is provided with an adjusting hole 101. The adjustment holes 101 are strip-shaped holes. The stopper 130 is fitted to the adjustment hole 101 and is capable of adjusting a position in a length direction of the adjustment hole 101 so as to switch between a first position and a second position.

The second connecting portion 120 has a matching structure matched with the limiting member 130.

Specifically, as shown in fig. 2, the matching structure is a groove 102 formed on the second connecting portion 120. Referring to fig. 1, when the second connecting portion 120 is in the open state, the limiting member 130 is at the first position. At this time, the limiting member 130 is engaged with the groove 102, so that the limiting member 130 can block the bottom wall of the groove 102, so as to prevent the second connecting portion 120 from rotating in the first direction, and further, the second connecting portion 120 can be maintained in the open state. The first direction is a rotation direction when the second connecting portion 120 is switched to the folded state (in fig. 1, the rotation direction when one end of the second connecting portion 120 away from the first connecting portion 110 rotates downward).

Further, since the limiting member 130 is engaged with the groove 102, the groove 102 can limit the position of the limiting member 130, and the limiting member 130 is prevented from moving to the second position, so that the second connecting portion 120 can be maintained in the open state. In this embodiment, the sidewall of the groove 102 blocks the limiting member 130 from moving along the length direction of the adjusting hole 101, so as to block the limiting member 130 from moving from the first position to the second position.

The limiting member 130 is separated from the matching structure when in the second position, so that the second connecting portion 120 can be switched to the folded state.

Specifically, the limiting member 130 can be released by the groove 102, and the limiting member 130 is moved to the second position along the adjusting hole 101 (moved leftward along the position of the limiting member 130 in fig. 1). At this time, the limiting member 130 is separated from the groove 102, so that the limiting member 130 does not block the bottom wall of the groove 102, and the second connecting portion 120 can rotate in the first direction to switch from the open state to the folded state.

Referring to fig. 3, the folding structure 100 may be used with the balance car 10. The balance car 10 includes a lever 11, a seat cushion 12, a car body 13, and a folding structure 100. The control rod 11 is fixedly connected with the vehicle body 13 and is used for controlling the operation of the vehicle body 13. The seat cushion 12 is fixedly connected to the second connecting portion 120, and the first connecting portion 110 is fixedly connected to the control lever 11.

In the above folding structure, when the second connecting portion 120 is in the open state, the limiting member 130 is in the first position and is engaged with the engaging structure, so that the second connecting portion 120 can be prevented from rotating in the first direction, and further the second connecting portion 120 can be kept in the open state, that is, the seat cushion 12 can be in the open state relative to the control lever 11, and a user of the balance bike can stably sit on the seat cushion to run. The limiting member 130 is separated from the matching structure when in the second position, so that the second connecting portion 120 can be switched to the folded state, and the seat cushion 12 can be in the folded state relative to the control rod 11, thereby facilitating the storage and transportation of the balance car 10.

It will be appreciated that the folding structure 100 may also be used for other structures that require folding, such as folding of a scooter cushion, folding of a bike cushion, and the like.

In one embodiment, the second connecting portion 120 can rotate in a direction opposite to the first direction when in the open state, so that the groove 102 can release the limiting member 130.

Specifically, in the present embodiment, the adjusting hole 101 is a strip-shaped hole, and the length direction of the strip-shaped hole extends along a straight line, so that when the limiting member 130 is at the first position, the sidewall of the groove 102 can prevent the limiting member 130 from moving to the second position along the length direction of the adjusting hole 101. It is understood that in other embodiments, the length direction of the adjustment hole 101 may also extend along an arc.

The process of switching the second connecting portion 120 from the folded state to the opened state is specifically as follows: by rotating the second connecting portion 120 in a direction opposite to the first direction (in fig. 1, the rotating direction when the end of the second connecting portion 120 away from the first connecting portion 110 rotates upward) for a certain angle, the opening of the groove 102 rotates in the direction opposite to the first direction until the opening of the groove 102 rotates to the length direction of the adjusting hole 101, so that the limiting member 130 can be moved out of the opening of the groove 102 in the length direction of the adjusting hole 101 until the limiting member 130 is moved (to the left in fig. 1) to the second position, and at this time, the groove 102 releases the limiting member 130. Since the limiting member 130 moves to the second position, the rotation of the second connecting portion 120 is not blocked, and at this time, the second connecting portion 120 rotates along the first direction, so that the second connecting portion 120 can be switched from the open state to the folded state.

The process of switching the second connecting portion 120 from the folded state to the unfolded state is specifically: the second connecting portion 120 is rotated in a direction opposite to the first direction until the opening of the groove 102 faces the limiting member 130, and at this time, the limiting member 130 can be moved from the second position to the first position, and then the limiting member 130 enters the opening of the groove 102. The second connecting portion 120 is rotated by a certain angle along the first direction, so that the limiting member 130 is matched with the groove 102, and the second connecting portion 120 is switched to the open state.

Referring to fig. 2, in an embodiment, the folding structure 100 further includes a spring 150. One end of the spring 150 is connected to the limiting member 130, and the other end is connected to the first connecting portion 110. The restoring force of the spring 150 is used to switch the limiting member 130 from the second position to the first position, and the limiting member 130 can be switched from the first position to the second position by overcoming the restoring force of the spring 150.

Specifically, referring to fig. 2, in the present embodiment, one end of the first connecting portion 110 has a spring mounting hole 103. The first connecting portion 110 further includes a flange 114 integrally formed with the top wall 111, the flange 114 forms an included angle with the top wall 111, and the spring mounting hole 103 is formed on the flange 114. The hook ring 151 of one end of the spring 150 hooks the first connection portion 110 through the spring mounting hole 103. The hook ring 152 at the other end of the spring 150 hooks the limiting member 130.

When the second connecting portion 120 is switched from the folded state to the open state, the second connecting portion 120 rotates in the direction opposite to the first direction until the opening of the groove 102 faces the limiting member 130, and the restoring force of the spring 150 can make the limiting member 130 automatically enter the opening of the groove 102, so as to facilitate the operation when the second connecting portion 120 is switched from the folded state to the open state.

When the limiting member 130 is switched from the first position to the second position, the restoring force of the spring 150 can be overcome by moving the limiting member 130.

Referring to fig. 2, in an embodiment, an avoiding notch 104 is disposed at an end of the second connecting portion 120 close to the spring 150, and the avoiding notch 104 is used for avoiding the spring 150 when the second connecting portion 120 is switched from the open state to the folded state.

Specifically, in the present embodiment, the avoiding notch 104 is disposed on the bottom wall 121 of the second connecting portion 120. In the process of switching the second connecting portion 120 from the opened state to the folded state, the second connecting portion 120 rotates in a direction opposite to the first direction, and one end of the second connecting portion 120 close to the spring 150 rotates upward in fig. 1. Because the avoiding notch 104 is arranged at one end of the second connecting part 120 close to the spring 150, the spring 150 can be avoided, and one end of the second connecting part 120 close to the spring 150 is prevented from propping against the spring 150.

Referring to fig. 2, in an embodiment, when the second connecting portion 120 is in a folded state, the limiting member 130 abuts against the second connecting portion 120 by a restoring force of the spring 150.

Specifically, when the second connecting portion 120 is in the folded state, the limiting member 130 is in the second position. The stopper 130 has a tendency to move toward the first position due to the restoring force of the spring 150, so that the stopper 130 abuts against the second connecting portion 120. In the present embodiment, when the second connecting portion 120 is in the folded state, the groove surrounded by the bottom wall 121 and the two second side walls 122 faces away from the limiting member 130, and then the limiting member 130 abuts against the outer surface of the bottom wall 121 of the second connecting portion 120.

Since the limiting member 130 abuts against the second connecting portion 120, the limiting member 130 can block or prevent the second connecting portion 120 from rotating in a direction opposite to the first direction, so that the second connecting portion 120 can be stably in a folded state.

Referring to fig. 1 and 2, in an embodiment, the folding structure 100 further includes a handle 160. The handle 160 is rotatably coupled to the first coupling portion 110. The handle 160 is provided with a guide hole 105, the limiting member 130 is matched with the guide hole 105, and when the handle 160 rotates relative to the first connecting portion 110, the guide hole 105 guides the limiting member 130 to switch between a first position and a second position.

Specifically, as shown in fig. 1 and 2, in the present embodiment, the guide hole 105 is a strip-shaped hole. In this embodiment, the handle 160 is rotatably connected to the first connecting portion 110 via the rotating shaft 140. The handle 160 rotates relative to the first connection portion 110, and the side wall of the guide hole 105 drives the limiting member 130 to move, so as to guide the limiting member 130 to switch between the first position and the second position, thereby facilitating the movement of the limiting member 130.

Further, when the limiting member 130 is switched from the first position to the second position, the handle 160 operates the limiting member 130 to apply a force so as to overcome the restoring force of the spring 150.

Referring to fig. 2, in an embodiment, the first connecting portion 110 is provided with a first mounting hole 106. The second connecting portion 120 is provided with a second fitting hole 107. The folding structure 100 also includes a fitting 170. The second connecting portion 120 may be respectively engaged with the first and second fitting holes 106 and 107 by a fitting 170 in an opened state, so that the first and second connecting portions 110 and 120 are fixedly connected, and thus the second connecting portion 120 may be further stably in an opened state.

Specifically, the fitting 170 may be a stud. The fitting 170 may be engaged with the first and second fitting holes 106 and 107 by nut and stud engagement.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
