As such, the seat cushion frame 200 may be relatively movably coupled to the floor assembly of the vehicle, for example, the seat cushion frame 200 is slidably coupled to the floor assembly in the front-rear direction through the slide rail assembly 600, since the lower end of the back frame 100 is rotatably coupled to the seat cushion frame 200, the upper end of the back frame 100 is adapted to be coupled to the hat rack 400 of the vehicle through the pivot mechanism 300, when the seat cushion frame 200 moves forward with respect to the floor assembly, the lower end of the back frame 100 moves forward with the seat cushion frame 200 and rotates rearward with respect to the seat cushion frame 200, and during this, the portion of the pivot mechanism 300 coupled to the back frame 100 moves with respect to the portion of the pivot mechanism 300 coupled to the hat rack 400, by which the back frame 100 can smoothly rotate rearward and tilt, and when the seat cushion frame 200 moves rearward with respect to the floor assembly, the back frame 100 can smoothly rotate forward, thereby achieving the tilt angle adjustment of the back frame 100. When the position of the cushion frame 200 is fixed, the positions of the upper and lower ends of the back frame 100 remain unchanged, the force (mainly gravity) from the occupant borne by the back frame 100 is transmitted to the hat rack 400 through the pivot mechanism 300, but not all the force is transmitted to the connection part of the back frame 100 and the cushion frame 200, so that the stress condition of the connection part of the back frame 100 and the cushion frame 200 can be improved to a certain extent, the mode of the back frame 100 can be improved, the riding safety and riding experience can be improved, and the cost of the connection structure of the connection part of the back frame 100 and the cushion frame 200 can be reduced to a certain extent. In addition, the present utility model realizes the inclination adjustment of the back rest 100 by using the movement of the cushion frame 200 relative to the floor assembly, and in the case where the inclination requirements of the back rest 100 are consistent, for example, in the case where the back rest 100 is fixed relative to the cushion frame 200, the back rest 100 is rotated relative to the cushion frame 200 to realize the inclination adjustment, the requirement of the back rest 100 for the rear reserved space can be reduced to a certain extent, so that the maximum inclination angle of the back rest 100 of the rear seat can be enlarged to a certain extent in the case where the rear evacuation space is limited, and the riding comfort of the rear seat can be improved.

In this embodiment, optionally, the pivoting mechanism 300 includes a connection frame 310 and a sliding seat 320, the connection frame 310 is connected to the hat rack 400, a sliding guide portion 3101 is disposed on the connection frame 310, the sliding seat 320 is connected to the backrest frame 100, a sliding portion 3201 is disposed on the sliding seat 320, and the sliding portion 3201 is slidably and rotatably connected to the sliding guide portion 3101.

Specifically, the connection frame 310 is fixedly connected with the hat rack 400, for example, welded connection, and the connection frame 310 may also be configured as a split-type frame body, which is configured according to actual needs, and will be described in the following exemplary embodiments. The sliding seat 320 includes a seat body 321, the seat body 321 is fixedly connected with the backrest frame 100, a sliding portion 3201 is disposed on the seat body 321, the sliding portion 3201 is slidably and rotatably connected with the sliding guide portion 3101, the seat body 321 is a seat body that can slide and rotate relative to the connecting frame 310, and the seat body 321 is fixedly connected, for example welded, with the backrest frame 100.

The specific structures of the guide portion 3101 and the sliding portion 3201 are not limited, and they may be rotatable and slidable with respect to each other; for example, the guide portion 3101 is provided as a guide rail, and the sliding portion 3201 includes a slider slidably connected to the guide rail and a cylinder rotatably connected to the slider.

In this way, when the seat frame 200 moves forward with respect to the floor assembly, the lower end of the back frame 100 moves forward with the seat frame 200 and rotates backward with respect to the seat frame 200, during which the portion of the pivoting mechanism 300 connected to the back frame 100 moves with respect to the portion of the pivoting mechanism 300 connected to the hat and coat stand 400, specifically, the sliding seat 320 slides and rotates with respect to the connecting frame 310, the back frame 100 can smoothly rotate backward and tilt, and when the seat frame 200 moves backward with respect to the floor assembly, the back frame 100 can smoothly rotate forward, thereby achieving the tilt angle adjustment of the back frame 100.

At this time, the connecting frame 310 is connected to the hat rack 400, and the slide guide 3101 is provided on the connecting frame 310, so that the interval requirement of the slide guide 3101 with respect to the hat rack 400 in the front-rear direction can be satisfied by the structural design of the connecting frame 310, and the reliability of the support of the backrest 100 can be ensured.

As shown in fig. 2, alternatively, the sliding guide portion 3101 is a guide groove, the sliding portion 3201 is a sliding post, and the sliding post is axially inserted in the guide groove, and the axial direction of the sliding post is perpendicular to the moving direction of the cushion frame 200 relative to the floor assembly, and the cross-sectional shape of the sliding post is circular.

Specifically, when the cushion frame 200 is movable in the front-rear direction with respect to the floor assembly, the guide groove may be understood as extending in a plane parallel to the XZ plane, for example, when the guide groove is provided on the first plate body 3111 described later, the first plate body 3111 is parallel to the XZ plane, the slide column is inserted into the guide groove in the Y-axis direction, and the cross-sectional shape of the slide column is circular so that it can slide and rotate in the guide groove.

Thus, when the cushion frame 200 moves relative to the floor assembly and moves to a side away from the hatrack 400, the sliding post slides in the guide groove and rotates relative to the guide groove, so that the inclination angle of the back frame 100 is adjusted.

Referring to fig. 2 for exemplary illustration of the structure of the seat body 321, the seat body 321 is provided with a U-shaped bayonet, and is welded or detachably connected after being clamped with a stand pipe located at an edge of the backrest frame 100 in the Y-axis direction, for example, the seat body 321 is provided with a first limit screw 322 at a side facing away from the U-shaped bayonet, the first limit screw 322 is inserted into the guide slot and is fixedly connected with the seat body 321, for example, welded after being connected by threads, a portion of a cylinder of the first limit screw 322 near a large end thereof is not provided with threads for forming a sliding column, and the sliding column is in contact with an inner wall of the guide slot.

As shown in fig. 2, the guide slot may alternatively decrease in distance from the floor assembly in a direction away from the hatrack 400.

In particular, the distance of the guide groove from the floor assembly is understood to be the distance of the center of the guide groove in the groove width direction from the floor assembly.

Thus, when the seat frame 200 moves relative to the floor assembly and moves to a side away from the hatrack 400, the sliding post moves in the guide groove to a side away from the hatrack 400, on one hand, the sliding post rotates and moves downward relative to the guide groove, thereby achieving the inclination adjustment of the back rest 100, and on the other hand, the sliding post moves away from the hatrack 400, so that the distance between the sliding post and the hatrack 400, for example, between the sliding post and the front end plate 4102 of the hatrack 400 described later, increases, thereby satisfying the adjustment requirement of the inclination angle of the back rest 100 without causing the upper end of the back rest 100 to collide with the hatrack 400 due to the inclination of the back rest 100.

Optionally, the guide groove is integrally in an arc structure, and an opening of the arc structure is arranged downwards.

In this way, the inner wall of the guide groove below the sliding column is beneficial to supporting the sliding column, so that the acting direction of the supporting force of the lower inner wall of the guide groove to the sliding column is as far as possible towards the upper direction, and the position stability and the stress reliability of the backrest frame 100 are ensured when the cushion frame 200 does not move.

Alternatively, the line connecting the centers of the guide grooves in the width direction at the upper and lower ends thereof is at an angle of 40 ° to 50 ° with respect to the floor assembly. For example, the angle is 43-48, for example 45.

In this way, when the included angle is too large, the interval between the sliding column and the hat rack 400 is too small in the X-axis direction, so that the inclination angle of the backrest frame 100 is limited, and when the included angle is too small, the movement of the lower end of the backrest frame 100 along with the cushion frame 200 cannot be adapted to can be avoided.

Optionally, the circumferential edge of the guide groove is circumferentially provided with a first reinforcing edge 3114, the first reinforcing edge 3114 being flush with the inner wall of the guide groove.
