Through the structure of this embodiment, the cushion support supports the cushion, the seat support 120 supports the seat 100, the seatback support supports the seatback 300, the cushion support and the seatback support are hinged through the seatback link 310 and the seatback link 110, and preferably, the seat support 120, the seatback support, the seatback link 310 and the seatback link 110 form a parallelogram structure, so that the seat cushion and the seatback 300 can be simultaneously adjusted in height or folded and unfolded.
Referring again to fig. 5 and 6, in one embodiment, the cushion support further includes a chute 210, and the seatback link 310 is coupled to the seat link 110 by a hinge 400, the hinge 400 being slidable within the chute 210. In this embodiment, the seatback link 310 connects the seatback support and the seat cushion support, and is fixed in the chute 210 of the seat cushion support so as to be linearly slidable, and the seat link 110 connects the seat cushion support and the seat support 120, and is fixed in the chute 210 of the seat cushion support so as to be linearly slidable in the chute 210. Specifically, the seatback link 310 and the seat link 110 are coaxially hinged by a hinge shaft that slides in the slide groove 210.
In one embodiment, the hinge shaft further includes a locking structure that limits sliding of the hinge shaft. Specifically, when the hinge shaft slides to the leftmost side of the chute 210, the locking structure restricts the hinge shaft from sliding to the right side, and the seat 100 is in the unfolded state, so that the user can take a seat. When the locking structure is not operated, the hinge shaft 400 coaxially hinged to the seatback link 310 and the seat link 110 is not limited, and the seat 100 starts to fold as gravity starts to slide to the right side of the chute 210, and when the hinge shaft 400 slides to the rightmost side of the chute 210, the seat 100 completes folding, and the dimension of the seat 100 in the height direction is minimum, so that the seat is convenient to store.
Referring to fig. 1 to 4, in particular, a locking structure is further included, which is coupled with the hinge shaft 400 to limit movement of the hinge shaft 400 within the chute 210. The locking structure includes a first locking block 410 and a second locking block 420; one end of the first locking block 410 is connected to the hinge shaft 400, and the other end of the first locking block 410 and the second locking block 420 may abut against each other to limit the movement of the hinge shaft 400 in the chute 210.
In one embodiment, the seat cushion further includes a release structure 500, where the release structure 500 is connected to the locking structure, and the release structure can drive the second locking block 420 to move away from the first locking block 410. The second locking block 420 is provided with an elastic member 430, and the elastic member 430 is disposed between the second locking block 420 and the release structure 500. One end of the first locking block 410 and the second locking block 420, which are abutted against each other, is in a circular arc structure. The locking structure is also provided with a limiting structure to limit the displacement of the second locking block 420. The limiting structure allows the movement direction of the second locking piece 420 to be determined, and the movement direction is perpendicular to the movement direction of the first locking piece 410. The elastic member 430 automatically returns the second locking piece 420 to the locking position. When the first locking piece 410 moves in the chute 210 to collide with the second locking piece 420, the circular arc structure generates a component force of the second locking piece 420 in the moving direction thereof, the component force overcomes the elastic force of the elastic piece 430, the second locking piece 420 moves in a direction away from the first locking piece 410, and finally the second locking piece 420 does not block the first locking piece 410. At this time, the first locking piece returns to the leftmost side of the chute 210, the contact surfaces of the first locking piece and the second locking piece do not collide with each other, the force applied to the elastic piece 430 disappears, and the elastic force of the elastic piece 430 enables the second locking piece 420 to return to the locking position limiting the movement of the first locking piece 410. At this time, the seat 100 is unfolded and the user can sit.
In some embodiments, the left end of the chute 210 is defined as a locked position, corresponding to the state in which the seat 100 is deployed and can perform a seating function. The right end of the chute 210 is a folded position corresponding to a state where the seat 100 is not ridable in a folded state. The position between the ends of the chute 210 represents the process of folding or repositioning the seat 100. The above orientations are merely for convenience of description of the solution and are not meant to limit any actual orientation of the present patent.
When in the locked state, the second locking block 420 blocks the movement of the first locking block 410, thereby preventing the movement of the hinge shaft 400 in the slide slot 210.
When in the unlocked state, in some embodiments, the release structure 500 is a pull-cord structure, not limited herein. The release structure 500 may also be a combination of the release handle 510 and the pull cord, and in some embodiments, at least two locking structures are respectively located on two sides of the seat 100, and the corresponding sliding groove 210, hinge shaft 400, backrest link and seat link are also two, so that the release structure 500 can apply forces to the locking structures on two ends of the seat 100 at the same time. Preferably, the release structure may be located below the seat cushion, and when the release structure 500 drives the second locking block 420 to move in a direction away from the first locking block 410, the first locking block 410 is no longer subjected to the acting force of the second locking block 420, so that the hinge shaft 400 may move in the sliding slot 210 to complete unlocking.
When the release structure 500 no longer applies a force to the second locking piece 420, the second locking piece 420 returns to its original position under the elastic force of the elastic member 430, where the elastic member 430 may preferably be a spring or a memory alloy. The first locking piece 410 continues to move along the sliding groove 210, when the first locking piece 410 and the second locking piece 420 are contacted with each other, the surfaces of the first locking piece 410 and the second locking piece 420 are in an arc shape, the elastic piece 430 is extruded, the first locking piece 410 continues to move until reaching a locking state, and the first locking piece returns to a locking position, and at the moment, the elastic piece 430 continues to recover to be the original state, so that locking is completed.
In one embodiment, the seat support 120 includes a front support frame and a rear support frame that are parallel to each other; one end of the front support frame is hinged with the cushion, and the other end is hinged with the scooter; one end of the rear supporting frame is hinged with the cushion, and the other end is hinged with the scooter. The front and rear support frames form parallel links so that the seat 100 is always parallel during folding.

In one embodiment, the seat link 110 is hinged at one end to the seatback link 310 and connected at the other end to the rear support bracket. Specifically, the three lines of the rear support frame, the sliding groove 210 of the cushion support member, and the seat link 110 are closed-loop-travel triangles, if one end of the link in the sliding groove 210 is limited by the locking structure, the three sides of the triangle are determined, and at this time, the angle of the seat support member 120 is determined and stable, so that the seat 100 can realize a stable sitting function. Similarly, three lines of the seat back support, the sliding groove 210 of the seat cushion support and the seat back connecting rod 310 are closed-loop to form a triangle, if one end of the connecting rod in the sliding groove 210 is limited by the locking structure, the three sides of the triangle are determined, and at this time, the angle of the seat support 120 is determined and stable, so that the seat 100 can realize a stable riding function.
In one embodiment, the chair back 300 further comprises an armrest rotatably coupled to the chair back 300. Specifically, the armrests are secured to the back support and only rotate when the seat 100 is in the folded position, without disassembly and without affecting the height of the folded seat 100.
In one embodiment, the back support and the seat cushion support have an included angle ranging from 0 ° to 90 °. Specifically, the chair back supporting piece inclines to the inclined rear, can form a parcel feel for a user, is shielded from left and right, and is safer and more comfortable.
