Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0043] As vehicles continue to develop, the seat layout inside the vehicle is constantly changing to make the vehicle suitable for different scenarios. Especially for some station wagons or medium and large off-road vehicles, users can adjust the posture of the rear seats to improve comfort.

[0044] Common rear seats can use a driving mechanism to enable the entire seat to be moved and adjusted along the length direction of the vehicle, as well as the seat back to rotate relative to the seat cushion.

[0045] However, such rear seats may be interfered with by the vehicle body structure during posture adjustment, resulting in a limited range of motion of the rear seats.

[0046] In order to overcome the defects in the prior art, the present application provides a vehicle seat assembly and a vehicle, the vehicle seat assembly includes a seat, a sliding mechanism and a driving unit, the seat has a cushion and a backrest, the backrest and the cushion can be rotated and adjusted, the sliding mechanism includes a first connecting component and a second connecting component connected along the height direction of the vehicle, the first connecting component is connected to the vehicle floor, the second connecting component is connected to the seat, the driving unit is arranged on the sliding mechanism, the driving unit can drive the first connecting component to move along the length direction of the vehicle relative to the vehicle floor, and the second connecting component to move along the width direction of the vehicle relative to the first connecting component. In this way, the relative position of the seat in the vehicle cabin is adjustable along the length direction and the width direction of the vehicle, so that the interference between the seat and the internal structure of the vehicle can be avoided during the movement of the seat, so that the movement range of the seat posture adjustment is increased, and at the same time, the change of the relative position of the seat in the vehicle cabin can further change the spatial layout in the cabin, which is conducive to the movement of the occupant in the cabin.

[0047] The content of the utility model will be described in detail below with reference to the accompanying drawings so that those skilled in the art can understand the content of the utility model more clearly and in detail.

Figure 4 This is a structural exploded diagram of the first connecting component and the driving unit in the vehicle seat assembly provided in an embodiment of the present application.

[0049] Figure 5 A schematic structural diagram of a second connecting component and a driving unit in a vehicle seat assembly provided in an embodiment of the present application. Figure 6 The structural exploded diagram of the second connecting component and the driving unit in the vehicle seat assembly provided in the embodiment of the present application. Figure 1-Figure 6 As shown, the embodiment of the present application provides a vehicle seat assembly 100, which can be arranged in the rear row of the vehicle cabin, and each row can be provided with two vehicle seat assemblies 100. The vehicle seat assembly 100 in this embodiment includes a seat 110, a sliding mechanism 120 and a driving unit 130.

[0050] Among them, the seat 110 includes a seat cushion 1101 and a backrest 1102, the backrest 1102 is rotatably arranged relative to the seat cushion 1101 around a rotation axis, and 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, and the sliding mechanism 120 includes a first connecting component 1201 and a second connecting component 1202, the first connecting component 1201, the second connecting component 1202 and the seat cushion 1101 are connected in sequence along the height direction of the vehicle, the first connecting component 1201 is connected to the floor of the vehicle, and the first connecting component 1201 is movably arranged relative to the floor along the length direction (X direction) of the vehicle, and the second connecting component 1202 is movably arranged relative to the first connecting component 1201 along the width direction of the vehicle; 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.

[0051] The vehicle seat assembly 100 in this embodiment enables the seat 110 to move along the length direction and the horizontal direction of the vehicle through the first connecting component 1201 and the second connecting component 1202 in the sliding mechanism 120, so that the backrest 1102 and the internal structure of the cabin can be prevented from interfering with each other during the rotation adjustment of the backrest 1102 of the seat 110 relative to the seat cushion 1101, so that the adjustment angle or movement range of the backrest 1102 relative to the seat cushion 1101 can be increased. At the same time, the relative position of the seat 110 in the cabin changes through the sliding mechanism 120, so that the layout of the passenger activity space in the cabin changes, and the position of the seat 110 can be appropriately adjusted to facilitate the passengers to enter and exit the cabin and the movement of the members in the cabin.

[0052] Exemplarily, the seat 110 includes a seat cushion 1101 and a backrest 1102. The backrest 1102 and the seat cushion 1101 are hinged via a hinge shaft, and the hinge shaft extends along the width direction of the vehicle. It can be understood that the backrest 1102 rotates relative to the seat cushion 1101 around the axis of the hinge shaft, that is, the axis of the hinge shaft in this embodiment is the rotation axis. In the process of adjusting the angle of the backrest 1102 relative to the seat cushion 1101, it is inevitable that the backrest 1102 will hit the structure in the cabin, such as: door interior trim, wheel bag, etc. In this way, the backrest 1102 can no longer be adjusted. Therefore, this embodiment requires adjusting the sliding mechanism 120 to make the seat 110 avoid these structures.

[0053] Specifically, the first connecting component 1201 in the sliding mechanism 120 is relatively fixedly connected to the floor of the vehicle cabin, and the first connecting component 1201 is arranged to move relative to the floor along the length direction (X direction) of the vehicle, the second connecting component 1202 is connected to the first connecting component 1201 along the height direction of the vehicle, and the second connecting component 1202 is arranged to move relative to the first connecting component 1201 along the width direction (Y direction) of the vehicle, and the seat cushion 1101 of the seat 110 and the second connecting component 1202 are relatively fixedly connected along the height direction of the vehicle. In this way, when the first connecting component 1201 moves along the length direction of the vehicle, the seat 110 can move along the length direction of the vehicle, and when the second connecting component 1202 moves along the width direction of the vehicle, the seat 110 can move along the width direction of the vehicle. Through the mutual cooperation of the first connecting component 1201 and the second connecting component 1202, the seat 110 will not collide with the structure in the vehicle, and the movement unit of the adjustable posture of the backrest 1102 of the seat 110 relative to the seat cushion 1101 can be increased. Of course, the change in the position of the seat 110 also changes the spatial layout in the cabin. Proper adjustment of the position and posture of the seat 110 in the cabin can facilitate the movement of the occupants in the cabin. In addition, the position and posture of the seat 110 can be adjusted by the occupants themselves according to their usage habits and different needs to improve the user experience.

[0054] In order to facilitate the movement of the seat 110, the present embodiment adjusts the movement of the seat 110 along the length direction and the width direction of the vehicle through the driving unit 130. The driving unit 130 is arranged on the sliding mechanism 120. The driving unit 130 can be a telescopic member, and the movement of the first connecting component 1201 along the length direction and the movement of the second connecting component 1202 along the width direction are controlled by the telescopic change of the telescopic member. Of course, the driving unit 130 can also realize the movement change of the seat 110 along the length direction and the width direction of the vehicle through the mutual cooperation of the motor and the transmission mechanism.

[0055] The sliding mechanism 120 can be specifically arranged in a variety of ways. As one embodiment, there are two first connecting components 1201, and the two first connecting components 1201 are arranged at intervals along the width direction; there are two second connecting components 1202, and the two second connecting components 1202 are arranged at intervals along the length direction; the first connecting component 1201 and the second connecting component 1202 are connected along the height direction. In this way, the connection structure between the first connecting component 1201 and the second connecting component 1202 is stable, the motion transmission of the seat 110 is smoother, and the structural stability of the vehicle seat assembly 100 is improved.

[0056] like Figure 2 , Figure 3 and Figure 5As shown, two first connection components 1201 are arranged at intervals along the Y direction, both ends of each first connection component 1201 along the X direction are relatively fixedly connected to the vehicle floor, the second connection component 1202 is connected to the top of the first connection component 1201 along the height direction, and the two second connection components 1202 are arranged at intervals along the X direction, both ends of each second connection component 1202 along the Y direction are respectively connected to the top of the first connection component 1201, and each second connection component 1202 is connected to the bottom of the seat 110. In this way, the two first connection components 1201 and the two second connection components 1202 form a stable square structure in the projection of the vehicle height direction, so that the connection between the seat 110, the sliding mechanism 120 and the vehicle floor remains stable.

[0057] Further, the first connecting component 1201 moves relative to the floor along the X direction, and the second connecting component 1202 moves relative to the first connecting component 1201 along the Y direction. The movement of the first connecting component 1201 and the second connecting component 1202 can be the relative sliding of the internal structure of the first connecting component 1201 and the relative sliding of the internal structure of the second connecting component 1202. In an optional embodiment, at least one of the first connecting component 1201 and the second connecting component 1202 includes a sliding unit 1203, and the sliding unit 1203 includes a fixed seat 1204 and a sliding seat 1205. The sliding seat 1205 is slidably arranged relative to the fixed seat 1204 along a preset sliding direction, wherein the preset sliding direction is along the length direction or the width direction; the fixed seat 1204 of the second connecting component 1202 and the sliding seat 1205 of the first connecting component 1201 are relatively fixedly connected along the height direction.

[0058] Combination Figure 3 and Figure 4 As shown, the first connecting assembly 1201 includes a fixed seat 1204 and a sliding seat 1205, the fixed seat 1204 and the sliding seat 1205 cooperate with each other, the sliding seat 1205 and the fixed seat 1204 extend along the X direction, and the sliding seat 1205 slides along the X direction relative to the fixed seat 1204. The second connecting assembly 1202 is connected to the sliding seat 1205 of the first connecting assembly 1201, and the second connecting assembly 1202 is connected to the bottom of the seat 110, so that when the sliding seat 1205 of the first connecting assembly 1201 slides along the X direction relative to the fixed seat 1204, the sliding seat 1205 of the first connecting assembly 1201 drives the second connecting assembly 1202 and the seat 110 to move together along the X direction.

[0059] Combination Figure 2 and Figure 5In this embodiment, the second connecting assembly 1202 may also include a fixed seat 1204 and a sliding seat 1205. The fixed seat 1204 and the sliding seat 1205 of the second connecting assembly 1202 cooperate with each other. The sliding seat 1205 and the fixed seat 1204 extend along the Y direction, and the sliding seat 1205 slides relative to the fixed seat 1204 along the Y direction. The fixed seat 1204 of the second connecting assembly 1202 and the first connecting assembly 1201 are relatively fixedly connected along the height direction of the vehicle, and the sliding seat 1205 of the second connecting assembly 1202 is connected to the bottom of the seat 110, so that when the sliding seat 1205 of the second connecting assembly 1202 slides relative to the fixed seat 1204 along the Y direction, the seat 110 can be driven to move along the Y direction.

[0060] As a possible implementation, a slide rail 1206 is provided on the fixed seat 1204, and the slide rail 1206 extends along a preset sliding direction, and the sliding seat 1205 is slidably connected to the slide rail 1206. In this way, the first connecting component 1201 and the second connecting component 1202 can realize the movement of the sliding seat 1205 relative to the fixed seat 1204 along the preset sliding direction through their respective sliding units 1203. Among them, the cross-sectional shape of the slide rail 1206 can be a "J" shape or a "W" shape, and the cross-sectional shape of the slide rail 1206 is not specifically limited in this embodiment. It can be understood that the shapes of the sliding seat 1205 and the slide rail are adapted to each other so that the relative movement between the sliding seat 1205 and the fixed seat 1204 is smooth.

[0061] Specifically, the sliding unit 1203 of the first connecting component 1201 includes a first fixed seat 1204a and a first sliding seat 1205a. The first fixed seat 1204a is connected to the floor, and the sliding rail 1206 of the first fixed seat 1204a extends along the length direction; the first sliding seat 1205a slides relative to the first fixed seat 1204a along the length direction, and the first sliding seat 1205a is connected to the fixed seat 1204 of the second connecting component 1202.

[0062] Combination Figure 2-Figure 4 , the first fixed seat 1204a and the first sliding seat 1205a extend along the X direction, and correspondingly, the slide rail 1206 provided on the first fixed seat 1204a extends along the X direction, the first slide seat 1205a and the slide rail 1206 on the first fixed seat 1204a are adapted to each other, and the first slide seat 1205a slides relative to the slide rail 1206 along the X direction. In this embodiment, the first fixed seat 1204a and the floor of the vehicle are connected through the support 1207, and the first slide seat 1205a and the fixed seat 1204 of the second connecting assembly 1202 are connected. In this way, the first slide seat 1205a slides relative to the first fixed seat 1204a along the X direction, and can drive the second connecting assembly 1202 and the seat 110 to move together along the X direction.

[0063] For further information, see Figure 2 , Figure 3 , Figure 5 and Figure 6 The sliding unit 1203 of the second connecting assembly 1202 includes a second fixed seat 1204b and a second sliding seat 1205b. The second fixed seat 1204b and the first sliding seat 1205a are relatively fixedly connected. The slide rail 1206 of the second fixed seat 1204b extends along the width direction. The second sliding seat 1205b slides along the width direction relative to the second fixed seat 1204b. The second sliding seat 1205b is connected to the seat 110. In this way, the sliding unit 1203 of the second connecting assembly 1202 can realize the sliding of the seat 110 along the width direction of the vehicle.

[0064] The second fixed seat 1204b and the second sliding seat 1205b in this embodiment have the same structure as the first fixed seat 1204a and the second fixed seat 1204b in the first connecting assembly 1201, and the structure of the second fixed seat 1204b and the second sliding seat 1205b will not be described in detail in this section. The difference is that the second fixed seat 1204b and the second sliding seat 1205b are arranged along the Y direction. It can be understood that the second fixed seat 1204b and the second sliding seat 1205b are both extended along the Y direction, that is, the slide rail 1206 on the second fixed seat 1204b extends along the Y direction, and accordingly, the second sliding seat 1205b slides relative to the second sliding seat 1205b along the Y direction through the slide rail 1206.

[0065] The second fixed seat 1204b and the first sliding seat 1205a are relatively fixedly connected through the connecting piece 1208, and the second sliding seat 1205b and the bottom of the seat 110 are relatively fixedly connected. On the basis of the above-mentioned embodiment, the first sliding seat 1205a slides along the X direction relative to the first fixed seat 1204a through the slide rail 1206, driving the second fixed seat 1204b, the second sliding seat 1205b and the seat 110 to slide along the X direction as a whole. The second sliding seat 1205b moves along the Y direction relative to the second fixed seat 1204b through the slide rail 1206, and the second sliding seat 1205b drives the seat 110 to move along the Y direction. By setting the sliding unit 1203 of the first connecting component 1201 and the sliding unit 1203 of the second connecting component 1202, the seat 110 can be moved along the X direction or the Y direction. In this way, the relative position of the seat 110 in the cabin can be adjusted to avoid movement interference between the seat 110 and the internal structure of the vehicle when adjusting the backrest 1102 of the seat 110, thereby increasing the movement range of the seat 110 posture adjustment and changing the spatial layout in the cabin to provide passengers with a movement space or route that is convenient for walking or moving, thereby improving the passengers' seat experience of the vehicle.

[0066] On the basis of the above-mentioned embodiment, the driving unit 130 includes a motor 1301, a screw rod 1302 and a screw kit 1303. The screw rod 1302 is connected to the fixed seat 1204. The screw kit 1303 is sleeved on the outside of the screw rod 1302 and connected to the sliding seat 1205. The screw rod 1302 rotates around the axis of the screw rod 1302 relative to the screw kit 1303 so that the sliding seat 1205 moves along a preset sliding direction; the motor 1301 is connected to the screw kit 1303, and the motor 1301 drives the screw rod 1302 to rotate, wherein the extension direction of the axis of the screw rod 1302 is the same as the sliding direction of the sliding seat 1205.

[0067] Combination Figure 2-Figure 6 As shown, when the driving unit 130 drives the first connecting assembly 1201 to move relative to the floor along the X direction, the screw rod 1302 and the first fixed seat 1204a of the first connecting assembly 1201 are relatively fixedly connected, the screw set 1303 is sleeved on the outside of the screw rod 1302, and the screw set 1303 and the first sliding seat 1205a are relatively fixedly connected, wherein the screw rod 1302 extends along the X direction, and the screw rod 1302 rotates around its own axis relative to the screw set 1303, so that the screw set 1303 will move along the axial direction of the screw rod 1302, and drive the first sliding seat 1205a to slide relative to the first fixed seat 1204a along the X direction. The rotation of the screw set 1303 around its own axis in this embodiment is driven by the motor 1301. The motor 1301 is arranged on the screw set 1303.

[0068] The connection mode of the motor 1301, the screw rod 1302 and the screw assembly 1303 driving the second connection assembly 1202 to move along the Y direction is the same as the connection mode in the first connection assembly 1201, and will not be repeated in this section. The difference is that when the screw rod 1302 in the driving unit 130 is connected with the second fixed seat 1204b in the second connection assembly 1202, the extension direction of the screw rod 1302 is the same as the extension direction of the second fixed seat 1204b, that is, the screw rod 1302 extends along the X direction. At this time, the screw rod 1302 rotates around its own axis relative to the screw assembly 1303, and the screw assembly 1303 can drive the second sliding seat 1205b to move relative to the second fixed seat 1204b along the Y direction.

[0069] Specific, combined Figure 4 and Figure 6The screw assembly 1303 includes a body 1304, a worm (not shown in the figure) and a worm wheel (not shown in the figure). The body 1304 is connected to the sliding seat 1205, and the body 1304 is sleeved on the outside of the screw 1302. The body 1304 has a receiving cavity (not shown in the figure); the worm and the worm wheel are located in the receiving cavity, the worm wheel and the worm are adapted, the axis of the worm and the axis of the worm wheel are perpendicular to each other, the worm wheel is sleeved on the screw 1302, and the screw 1302 rotates around the axis of the screw 1302 relative to the worm wheel; the output shaft 1305 of the motor 1301 is connected to the worm so that the worm rotates around the axis of the worm. Through the transmission structure of the motor 1301, the worm and the worm wheel, one motor 1301 can synchronously drive the movement of the two sliding seats 1205 relative to the fixed seat 1204.

[0070] Since the connection structure and driving method of the driving unit 130 and the first connecting component 1201 and the second connecting component 1202 are the same, this section takes the connection between the driving unit 130 and the first connecting component 1201 as an example for specific description.

[0071] The two first connecting components 1201 are arranged at intervals along the Y direction, and the motor 1301 has two output shafts 1305. The two output shafts 1305 are arranged on opposite sides of the motor 1301 along the Y direction, so that the side of each output shaft 1305 away from the motor 1301 can be connected to the screw assembly 1303 on each first sliding seat 1205a.

[0072] The output shaft 1305 extends along the Y direction into the accommodating cavity of the screw sleeve 1303 and is connected to the worm in the accommodating cavity, so that the worm and the output shaft 1305 can rotate synchronously. The worm wheel is located on the body 1304 and is sleeved on one side of the screw 1302, and the worm wheel is sleeved on the screw 1302. The worm wheel and the worm are adapted to each other and meshed for transmission. In this way, the worm wheel and the screw rotate relative to each other, and the worm wheel can move along the axis of the screw. It can be understood that the body 1304 will drive the first sliding seat 1205a to move along the Y direction.

[0073] Different from the first connecting assembly 1201, the second connecting assembly 1202 is arranged at intervals along the X direction, and the output shaft 1305 of the motor 1301 is arranged on opposite sides of the motor 1301 along the X direction and connected to the screw assembly 1303 on the second sliding seat 1205b. In this way, the body 1304 can be driven to drive the second sliding seat 1205b to move along the X direction, so that the relative position of the seat 110 changes.

[0074] It should be noted that the motor 1301 can be fixed on the sliding seat 1205 through the mounting bracket 1306 to provide support for the motor 1301 and stabilize the connection between the driving unit 130 and the sliding mechanism 120.

[0075] In some embodiments, the drive unit 130 further includes a controller (not shown in the figure), the controller is electrically connected to the motor 1301, and the controller is configured to control the motor 1301 to drive the seat 110 to move along at least one of the length direction of the vehicle and the width direction of the vehicle. In this way, the position adjustment process of the seat 110 is controllable through the setting of the controller.

[0076] The controller can be set on the seat 110 or on the vehicle body. The controller controls the start and stop of the motor 1301 to adjust the movement of the seat 110 in the length direction of the vehicle or in the width direction of the vehicle. Of course, the controller can also control the rotation of the backrest 1102 of the seat 110 relative to the seat cushion 1101 to make the posture of the seat 110 conform to the sitting posture or requirements of the occupant, thereby improving the occupant's riding comfort and product experience.

[0077] The controller can control the seat 110 to change various posture modes, such as the initial posture, the flat posture, etc. In the initial posture, the posture of the seat 110 is the initial posture set when leaving the vehicle. In the flat posture, the seat 110 moves along the X direction and the Y direction, and the backrest 1102 of the seat 110 rotates around the rotation axis relative to the seat cushion 1101, so that the backrest 1102 and the seat 110 can be extended in the length direction of the vehicle as much as possible to provide rest for the passengers. The seat 110 is converted in different postures through the controller to meet the needs of the passengers.

[0078] The vehicle seat assembly in this embodiment includes a seat, a sliding mechanism and a driving unit. The seat includes a seat cushion and a backrest, the backrest is arranged to rotate relative to the seat cushion around a rotation axis, and the rotation axis is along the width direction of the vehicle; the sliding mechanism is connected to the bottom of the seat cushion, and the sliding mechanism includes a first connecting component and a second connecting component, the first connecting component, the second connecting component and the seat cushion are connected in sequence along the height direction of the vehicle, the first connecting component is connected to the floor of the vehicle, and the first connecting component is arranged to move relative to the floor along the length direction of the vehicle, and the second connecting component is arranged to move relative to the first connecting component along the width direction of the vehicle; the driving unit is arranged on the sliding mechanism and is configured to drive the seat to move along at least one of the length direction and the width direction. Through such a structural arrangement, it is possible to avoid motion interference with the internal structure of the vehicle, increase the motion range of the seat posture adjustment, and further change the spatial layout in the cabin to facilitate the movement of the occupants in the cabin.
