[0049] In this embodiment, the flipping mechanism is a mechanical power-assisted flipping mechanism, specifically, the mechanical power-assisted flipping mechanism further includes a flipping power-assisting assembly 4, and the flipping power-assisting assembly 4 is connected to the rotating shaft 2. The flipping power-assisting assembly 4 can not only offset part of the gravity of the seat body when the seat is changed from the sitting state to the storage state, so that the seat body can be stored in the pit more smoothly, but also offset part of the gravity of the seat body when the seat is changed from the storage state to the sitting state, so as to reduce the external force required to flip the seat body; therefore, the flipping mechanism provided by the utility model can play a power-assisting role in the flipping process of the seat through the flipping power-assisting assembly 4.

A limit member 41 and a first spring 42 are used. Since the rotation of the rotating shaft 2 drives the limit member 41 to rotate, the rotation of the limit member 41 can change the abutment position of the first action arm 421 and the second action arm 422, thereby realizing the storage and release of the elastic potential energy of the first spring 42, and further achieving the purpose of providing an assist during the flipping process of the seat through the flipping assist component 4.

[0051] In this embodiment, the first spring 42 is a torsion spring.

[0052] In some other embodiments, the first spring 42 may also be a tension spring, a compression spring, or any other spring that can store and release elastic potential energy to assist in the flipping process of the seat, which is not limited here.

[0053] In some embodiments, the limiting member 41 is provided with a square hole for the shaft 2 to pass through and adapted to the square limiting portion of the shaft 2 . The limiting member 41 is sleeved on the shaft 2 through the square hole and rotates along with the rotation of the shaft 2 .

[0054] The flip assist assembly 4 also includes a second spring 43, which is sleeved on the rotating shaft 2 and has a third action arm 431 and a fourth action arm 432; wherein, when the limiting member 41 is in the first position, the third action arm 431 abuts against the first support portion 314, and the fourth action arm 432 abuts against the second limiting wall 412; when the limiting member 41 is in the second position, the third action arm 431 abuts against the first limiting wall 411, and the fourth action arm 432 abuts against the second support portion 315. The abutting position of the third action arm 431 and the fourth action arm 432 is changed by the rotation of the limiting member 41, thereby realizing the storage and release of the elastic potential energy of the third spring, so that the flip assist assembly 4 can play a greater assisting role in the flipping process of the seat.

[0055] In this embodiment, the second spring 43 is a torsion spring.

[0056] In some other embodiments, the second spring 43 may also be a tension spring, a compression spring, or any other spring that can store and release elastic potential energy to assist in the flipping process of the seat, which is not limited here.

[0057] In this embodiment, the first spring 42 and the second spring 43 have different elastic coefficients.

[0058] In some other implementations, the elastic coefficients of the first spring 42 and the second spring 43 may be the same.

The output shaft 521 is inserted into the receiving chamber through the second through hole 5113 to be connected to the reduction transmission assembly. The driving motor 52 drives the rotating shaft 2 to rotate around the central axis of the rotating shaft 2 through the reduction transmission assembly. By arranging the reduction transmission assembly in the accommodating chamber, the reduction box 511 can be used to protect the reduction transmission assembly and to block the noise generated by the reduction transmission assembly to reduce the noise. At the same time, the first rotating shaft 2 and the output shaft 521 of the driving motor 52 are respectively extended into the accommodating chamber through the first through hole 310 and the second through hole 5113 to be connected with the reduction transmission assembly. The reduction transmission assembly, part of the first rotating shaft 2 and part of the driving motor 52 can be integrated in the accommodating chamber to reduce the overall volume space of the electric flip assist mechanism. Therefore, the electric flip assist mechanism provided by the utility model can have a smaller volume space and lower noise by integrating the reduction transmission assembly in the accommodating chamber.

[0062] The reduction transmission assembly is a reduction transmission assembly of the prior art and will not be described in detail here.

[0063] The flip mechanism also has a fourth direction D, which intersects with the first direction A; the second through hole 5113 is opened in the reduction box 511 along the first direction A, and the third through hole 5114 is opened in the reduction box 511 along the fourth direction D. The second through hole 5113 and the third through hole 5114 are respectively arranged in different directions, so that the reducer 51 can be prevented from having an excessive length in the same direction, so that the flip mechanism can obtain a smaller volume space.

[0064] In this embodiment, the fourth direction D and the second direction B intersect.

[0065] The reduction box 511 includes a box body 5111 and a box cover 5112, and the box cover 5112 is detachably connected to the box body 5111. The detachable connection method is convenient for assembling and disassembling the components of the reduction box 51.
