FIG. 5 is a schematic illustration of a second link assembly and drive unit in a vehicle seat assembly according to an embodiment of the present application. FIG. 6 is an exploded view of a second link assembly and drive unit in a vehicle seat assembly according to an embodiment of the present application. As shown in fig. 1-6, embodiments of the present application provide a vehicle seat assembly 100 that may be disposed in a rear row of a vehicle cabin, with two vehicle seat assemblies 100 disposed in each row. The vehicle seat assembly 100 in this embodiment includes a seat 110, a slide mechanism 120, and a drive unit 130.

The seat 110 comprises a seat cushion 1101 and a backrest 1102, the backrest 1102 is rotatably arranged relative to the seat cushion 1101 around a rotation axis, the rotation axis is along the width direction (Y direction) of the vehicle, the sliding mechanism 120 is connected to the bottom of the seat cushion 1101, the sliding mechanism 120 comprises a first connecting assembly 1201 and a second connecting assembly 1202, the first connecting assembly 1201, the second connecting assembly 1202 and the seat cushion 1101 are sequentially connected along the height direction of the vehicle, the first connecting assembly 1201 is connected with the floor of the vehicle, the first connecting assembly 1201 is movably arranged relative to the floor along the length direction (X direction) of the vehicle, the second connecting assembly 1202 is movably arranged relative to the first connecting assembly 1201 along the width direction of the vehicle, and the driving unit 130 is arranged on the sliding mechanism 120 and is configured to drive the seat 110 to move along at least one of the length direction and the width direction.

In the vehicle seat assembly 100 of the present embodiment, the first connecting assembly 1201 and the second connecting assembly 1202 in the sliding mechanism 120 enable the seat 110 to move along the vehicle length direction and the horizontal direction, so that the internal structure of the backrest 1102 and the cabin are prevented from interfering with each other during the rotation adjustment of the backrest 1102 of the seat 110 relative to the seat cushion 1101, and the adjustment angle or the movement range of the backrest 1102 relative to the seat cushion 1101 can be increased. Meanwhile, the seat 110 changes the relative position in the cabin through the sliding mechanism 120, so that the active space layout of the passengers in the cabin changes, and the position of the seat 110 can be properly adjusted, thereby facilitating the passengers to enter and exit the cabin and the passengers to move in the cabin.

Illustratively, the seat 110 includes a seat cushion 1101 and a backrest 1102, the backrest 1102 and the seat cushion 1101 are hinged by a hinge shaft extending in the width direction of the vehicle, and it is understood that the backrest 1102 rotates about the axis of the hinge shaft with respect to the seat cushion 1101, that is, the axis of the hinge shaft in this embodiment is the rotation axis. The backrest 1102 is difficult to avoid touching structures in the cabin, such as door trim, wheel bags, etc., during the adjustment of the angle relative to the seat cushion 1101. Thus, the backrest 1102 cannot be adjusted any further. Therefore, the present embodiment requires the seat 110 to avoid these structures by adjustment of the slide mechanism 120.

Specifically, the first connection unit 1201 in the slide mechanism 120 is fixedly connected to the floor of the cabin of the vehicle, and the first connection unit 1201 is movably disposed along the longitudinal direction (X direction) of the vehicle with respect to the floor, the second connection unit 1202 is movably disposed along the height direction (Y direction) of the vehicle with respect to the first connection unit 1201, and the seat cushion 1101 of the seat 110 is fixedly connected to the second connection unit 1202 along the height direction (Y direction) of the vehicle with respect to the first connection unit 1201. Thus, when the first link assembly 1201 is moved in the longitudinal direction of the vehicle, the seat 110 is moved in the longitudinal direction of the vehicle, and the second link assembly 1202 is moved in the width direction of the vehicle, and the seat 110 is moved in the width direction of the vehicle. By the mutual engagement of the first link assembly 1201 and the second link assembly 1202, the seat 110 does not collide with the structure in the vehicle, and the movement unit of the backrest 1102 of the seat 110 with respect to the seat cushion 1101, which can adjust the posture, can be increased. Of course, the position of the seat 110 is changed, so that the space layout in the cabin is changed, and the movement of the passenger in the cabin can be facilitated by properly adjusting the position of the seat 110 in the cabin and the posture of the seat 110. In addition, the position and posture of the seat 110 can be adjusted by the passengers according to the using habits of the passengers and different requirements, so as to improve the experience of the users.

In order to facilitate movement of the seat 110, the present embodiment adjusts movement of the seat 110 in the longitudinal direction and the width direction of the vehicle by the driving unit 130.

As a possible implementation manner, the fixing base 1204 is provided with a sliding rail 1206, the sliding rail 1206 extends along a preset sliding direction, and the sliding base 1205 is slidingly connected with the sliding rail 1206. In this way, the first connection assembly 1201 and the second connection assembly 1202 can move the sliding seat 1205 along the preset sliding direction relative to the fixed seat 1204 through the respective sliding units 1203. The cross-sectional shape of the sliding rail 1206 may be a "table" shape or a "W" shape, and the cross-sectional shape of the sliding rail 1206 is not particularly limited in this embodiment. It will be appreciated that the shapes of the slide 1205 and the rail are adapted to smooth the relative movement between the slide 1205 and the fixed 1204.
