[0020] Please see Figures 1 to 5 This utility model provides a rear four-seat folding structure, including a seat body 1, a backrest 2, a first connecting block 3, a rotating frame 4, a driving component 5, a second connecting block 6, and a rotating linkage 7; the backrest 2 is fixedly connected to the seat body 1 and is located at the top of the seat body 1, the rotating frame 4 is assembled at the bottom of the seat body 1, the first connecting block 3 is rotated on the side of the rotating frame 4 away from the seat body 1, the driving component 5 is assembled on one side of the rotating frame 4, the rotating linkage 7 is rotatably connected to the backrest 2 and is located on the outside of the backrest 2, and the second connecting block 6 is rotatably connected to the rotating linkage 7 and is located on the side of the rotating linkage 7 away from the backrest 2.

[0021] In this embodiment, the first connecting block 3 installs the rotating frame 4 inside the passenger compartment. The rotating frame 4 provides support for the seat body 1 and drives the seat body 1 to rotate, thereby adjusting the tilt angle of the seat body 1 and folding down the seat body 1 and the backrest 2. The second connecting block 6 is fixed inside the passenger compartment and connected to the backrest 2 via the rotating linkage 7. It assists the backrest 2 in rotating when the seat body 1 rotates. When adjusting the angle of the seat body 1, the passenger activates the drive component 5 via the controller, driving the rotating frame 4 to rotate on the first connecting block 3, causing the seat body 1 to rotate and tilt. Simultaneously, the backrest 2 follows the rotation of the seat body 1 and rotates on the second connecting block 6 under the action of the rotating linkage 7, realizing the operation of folding down the seat body 1. The operation is convenient and quick, eliminating the need for passengers to operate multiple positions of the seat. This solves the problem of complex and inconvenient operation in existing rear four-part seat folding structures.

[0022] Furthermore, the rotating frame 4 includes a rotating frame body 8 and a rotating bolt 9. The rotating frame body 8 is fixedly connected to the seat body 1 and is located at the bottom of the seat body 1. The rotating bolt 9 is rotatably connected to the rotating frame body 8 and passes through the first connecting block 3.

[0023] In this embodiment, the rotating bolt 9 is used to connect the rotating frame body 8 and the first connecting block 3, which enables the rotating frame body 8 to rotate on the first connecting block 3. The rotating frame body 8 is driven by the driving member 5, thereby driving the seat body 1 to rotate.

[0024] Furthermore, the driving component 5 includes a drive motor 10, a rotating shaft 11, a drive wheel 12, and a reset component 13. The drive wheel 12 is mounted on one side of the rotating frame body 8. The rotating shaft 11 is fixedly connected to the drive wheel 12 and is located on one side of the drive wheel 12.

[0025] In this embodiment, the passenger starts the drive motor 10 via the control button on the controller. The drive motor 10 starts and drives the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 drives the drive wheel 12 to rotate, thereby driving the rotating frame body 8 to rotate. The rotating frame body 8 drives the seat body 1 to rotate and adjust the angle. The reset member 13 is provided for the reset of the rotating frame body 8, thereby driving the seat body 1 to reset.

[0026] Furthermore, the reset component 13 includes a compression block 14 and a torsion spring 15. The compression block 14 is fixedly connected to the drive wheel 12 and is located outside the drive wheel 12. The torsion spring 15 is assembled on the outside of the rotating frame body 8.

[0027] In this embodiment, while the drive wheel 12 drives the rotating frame body 8 to rotate, it also drives the compression block 14 to rotate. The rotation of the compression block 14 compresses the torsion spring 15. When the seat body 1 needs to be reset, it is only necessary to stop the drive motor 10 and remove the force on the drive wheel 12. The torsion spring 15 can then reset and push the compression block 14 to reset, thereby causing the drive wheel 12 to drive the rotating frame body 8 to reset, and thus causing the seat body 1 to reset.

[0028] Furthermore, the first connecting block 3 includes a connecting block body 16 and a limiting block 17. The connecting block body 16 is assembled on the side of the rotating frame body 8 away from the seat body 1. The limiting block 17 is fixedly connected to the connecting block body 16 and is located on one side of the connecting block body 16.

[0029] In this embodiment, the connecting block body 16 is fixed inside the carriage by bolts, and the limiting block 17 is provided to limit the rotation frame body 8.
