[0035] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0036] like Figure 1 As shown, an embodiment of the utility model provides a vehicle, including a seat, the seat including a slide rail 3, a seat cushion 1 and a backrest 2, the slide rail 3 is installed on a bottom plate in the vehicle, and the seat cushion 1 and the backrest 2 are arranged independently of each other.

[0037] The seat cushion 1 includes a seat cushion body 11, a first rotating shaft 13, a first driving device 14 and a first connecting frame 12. The seat cushion body 11 and the first connecting frame 12 are rotationally connected via the first rotating shaft 13. The first driving device 14 is used to drive the first rotating shaft 13 to rotate relative to the first connecting frame 12.

[0038] The backrest 2 includes a backrest body 21 , a second rotating shaft, a second driving device 23 and a second connecting frame 22 . The backrest body 21 is rotatably connected to the second connecting frame 22 via the second rotating shaft. The second driving device 23 is used to drive the second rotating shaft to rotate relative to the second connecting frame 22 .

[0039] The first connecting frame 12 and the second connecting frame 22 are slidably connected to the slide rail 3 .

[0040] Since the backrest 2 and the seat cushion 1 of the seat are independently arranged, the backrest 2 and the seat cushion 1 can be folded separately. Specifically, when the seat cushion 1 needs to be folded, the first driving device 14 electrically drives the first rotating shaft 13 to rotate relative to the first connecting frame 12, so that the first rotating shaft 13 drives the seat cushion body 11 to rotate, and the seat cushion 1 is flipped, so that the seat cushion 1 can meet the layout requirements of different vehicle use scenarios. When the backrest 2 needs to be folded, the second driving device 23 electrically drives the second rotating shaft to rotate relative to the second connecting frame 22, so that the second rotating shaft drives the backrest body 21 to rotate, and the backrest 2 is flipped, so that the backrest 2 can meet the layout requirements of different vehicle use scenarios.

[0041] Moreover, the first connecting frame 12 of the seat cushion 1 and the second connecting frame 22 of the backrest 2 are both slidably connected to the slide rail 3. Since the seat cushion 1 and the backrest 2 are independently arranged, the seat cushion 1 and the backrest 2 can be moved independently by relying on the slide rail 3, so that the seat cushion 1 can meet the layout requirements of more vehicle usage scenarios.

[0042] Figure 1 This is a layout diagram of the seats in a vehicle in a vehicle usage scenario. The vehicle has three rows of seats, namely the front row, the middle row and the back row. It is generally an SUV or MPV model. Figure 1 Only the middle row and the rear row seats are shown. The seat cushion 1 of the middle row seat is flipped forward 180°, the backrest 2 of the middle row seat is folded forward to be flush with the seat cushion 1, the seat cushion 1 of the rear row seat is flipped forward at a certain angle and moved forward relying on the slide rail 3, and the backrest 2 of the rear row seat is moved forward and close to the seat cushion 1. Through this layout, the trunk storage space can be maximized.

[0043] Figure 2 for Figure 1 The layout diagram of the vehicle seats in another vehicle usage scenario, wherein the seat cushion 1 of the rear seat is flipped forward 180°, the backrest 2 of the middle seat is folded forward and flush with the seat cushion 1, the seat cushion 1 of the rear seat is flipped forward 180°, and the backrest 2 of the rear seat is folded forward and flush with the seat cushion 1. Through this layout, a completely flat surface can be created to create a large bed mode.

[0044] It should be noted that Figure 1 and Figure 2 Only the flip angles of the seats in the vehicle in two vehicle use scenarios are shown, and the flip angles of the seat cushion 1 and the backrest 2 can be adjusted according to the needs of the actual vehicle use scenario. The number of seats can also be set according to the vehicle space and needs. For example, the seats can be set in two rows, namely the front seats and the rear seats.

[0045] In addition, a control button may be provided on the side of the seat to control the first drive device 14 and the second drive device 23 to operate so that the first rotating shaft 13 drives the seat cushion body 11 to flip and the second rotating shaft drives the backrest body 21 to flip.

[0046] In the vehicle of the present invention, the seat back 2 and the seat cushion 1 are independently arranged, so that the seat back 2 and the seat cushion 1 can be flipped separately, wherein the first drive device 14 can electrically drive the first rotating shaft 13 to rotate relative to the first connecting frame 12, so that the first rotating shaft 13 drives the seat cushion body 11 to rotate around the first rotating shaft 13, thereby realizing the electric flipping of the seat, and the second drive device 23 can electrically drive the second rotating shaft to rotate relative to the second connecting frame 22, so that the second rotating shaft drives the backrest body 21 to rotate around the second rotating shaft, thereby realizing the electric flipping of the backrest 2, saving manpower.

[0047] Moreover, since the seat back 2 and seat cushion 1 are independently arranged, the flip angles and positions of the seat back 2 and seat cushion 1 do not interfere with each other. The seat back 2 and seat cushion 1 can slide independently on the slide rail 3 to adjust the positions of the seat back 2 and seat cushion 1 respectively, making it suitable for more vehicle usage scenarios.

[0048] In one embodiment, if Figures 3 to 6 As shown, the seat cushion 1 further includes a first angle adjuster 15 fixed on the seat cushion body 11 , and the first rotating shaft 13 is transmission-connected to the first angle adjuster 15 .
