Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please see Figures 1-4 This utility model provides a rear four-seat movement mechanism, including a seat cushion 1, a backrest 2, a drive assembly, two transmission assemblies, two side sliding assemblies, and two limiting assemblies;

[0020] The backrest 2 is mounted on the seat cushion 1, the drive assembly is mounted on the bottom of the seat cushion 1, the two transmission assemblies are respectively mounted on the drive assembly, the two side sliding assemblies are respectively mounted between the vehicle body and the backrest 2, and the two limiting assemblies are respectively mounted on the side of the backrest 2 away from the side sliding assemblies.

[0021] In this embodiment, not shown in the vehicle body diagram, the seat cushion 1 provides the installation conditions for the backrest 2 and the drive assembly. When the car seat needs to be adjusted, the drive assembly is activated, which drives the two transmission components to rotate. The two transmission components drive the seat cushion 1 to rotate towards the side closer to the vehicle body. The seat cushion 1 drives the backrest 2 to slide backward on the two side sliding components. At the same time, the two limiting components rotate to limit the backrest 2, preventing the backrest 2 from occupying the rear seat space. Once the backrest 2 rotates to a preset angle, the rearward adjustment of the car seat can be completed. Conversely, the car seat can be adjusted forward, thus solving the problem that the backrest 2 occupies a lot of rear seat space when adjusting the existing car seat.

[0022] Furthermore, the drive assembly includes a drive component 3 and a rotating rod 4. The drive component 3 is installed at the bottom of the seat cushion 1, and the rotating rod 4 is fixedly connected to the output end of the drive component 3 and rotatably connected to the seat cushion 1.

[0023] In this embodiment, the operation of the driving component 3 can drive the rotating rod 4 to rotate forward or reverse. The rotation of the rotating rod 4 can drive the two transmission rods 5 to rotate towards the side closer to the vehicle body or away from the vehicle body.

[0024] Furthermore, the transmission assembly includes a transmission rod 5 and a support base 6. The transmission rod 5 is fixedly connected to the rotating rod 4 and is located on one side of the rotating rod 4. The support base 6 is rotatably connected to the transmission rod 5 and is fixedly connected to the vehicle body.

[0025] In this embodiment, the support base 6 provides the installation conditions for the transmission rod 5. The transmission rod 5 can be connected to the vehicle body through the support base 6. The rotation of the transmission rod 5 can drive the seat cushion 1 to be adjusted to the side closer to the vehicle body or the side farther away from the vehicle body.

[0026] Furthermore, the side-sliding assembly includes a side-sliding frame 7 and a slider 8. The side-sliding frame has a sliding groove 11. The side-sliding frame 7 is fixedly connected to the vehicle body and located on the vehicle body. The slider 8 is rotatably connected to the backrest 2 and located within the sliding groove 11.

[0027] In this embodiment, the slide groove 11 on the side slide 7 allows the slider 8 to move within it. The slider 8 can guide the backrest 2, improving the stability of the backrest 2 when it moves.

[0028] Furthermore, the limiting component includes a connecting plate 9 and a limiting rod 10. The connecting plate 9 is fixedly connected to the backrest 2 and located on one side of the backrest 2. The limiting rod 10 is rotatably connected to the connecting plate 9 and rotatably connected to the vehicle body.

[0029] In this embodiment, the connecting plate 9 provides installation conditions for the limiting rod 10. The backrest 2 and the limiting rod 10 can be connected through the connecting plate 9. When the backrest 2 is adjusted, the limiting rod 10 limits the backrest 2 to prevent the backrest 2 from moving out of the preset range and occupying the rear space of the car.

[0030] When the car seat needs to be adjusted, the drive unit 3 is activated, which drives the rotating rod 4 to rotate. The rotating rod 4 drives the two transmission rods 5 to rotate on the support seat 6 towards the side closer to the vehicle body. The two transmission rods 5 drive the seat cushion 1 to move towards the side closer to the vehicle body. The seat cushion 1 drives the two sliders 8 on the backrest 2 to slide backward in the groove 11 on the side slide frame 7. At the same time, the two limiting rods 10 rotate to limit the backrest 2, preventing the backrest 2 from occupying the rear space. Once the backrest 2 has rotated to a preset angle, the car seat can be adjusted backward. Conversely, the car seat can be adjusted forward, thus solving the problem that the backrest 2 occupies a lot of rear space when adjusting the existing car seat.
