The first motor 51 and the second motor 52 can work separately to make the backrest 20 and the seat cushion 30 move separately. The second motor 52 first drives the seat cushion 30 to rotate in a direction away from the backrest 20 to increase the distance between the seat cushion 30 and the backrest 20, and reserve enough space to accommodate the backrest 20. Then the first motor 51 can drive the backrest 20 to rotate in the direction of the base 10, thereby realizing the folding of the seat 100.

[0060] In another embodiment, after the second motor drives the seat cushion 30 to rotate, the first motor 51 can drive the backrest 20 to rotate in a direction away from the base 10 , thereby realizing the reclining of the seat 100 .

[0061] It can be understood that the angle between the backrest 20 and the seat cushion 30 can be adjusted by driving the backrest 20 to rotate through the first motor 51 alone. The driver and passenger can adjust the seat 100 according to their own wishes to adapt to drivers and passengers of different body shapes and provide a good riding experience for the driver and passenger.

[0062] The backrest 20 and the seat cushion 30 of the seat 100 of the present application are both capable of moving relative to the base 10. After movement, the backrest 20 and the seat cushion 30 can realize the folding or folding of the seat 100, thereby reducing the space occupied by the seat 100, so that more and larger items can be accommodated in the vehicle compartment.

[0063] Existing vehicle seats often require drivers and passengers to manually fold or lay down the seats, which requires many steps and takes a lot of time.
