The seat support positioning structure 2 is connected with the overturning pressing arm 1, and the driver 3 is in driving connection with the overturning pressing arm 1. The seat support positioning structure 2 is used for positioning and clamping the seat support A. The driver 3 can drive and control the overturning pressing arm 1 to overturn, so as to drive the seat support positioning structure 2 and the seat support A positioned on the seat support positioning structure to synchronously overturn, and therefore the seat support A can be positioned and pressed on the corresponding position of the rear floor B. Because the seat support positioning structure 2 can position and clamp the seat support A, the turnover anti-falling mechanism C can not fall or shift in the whole turnover anti-falling mechanism C to other upper part areas and the automatic clamping process, and the positioning precision is improved.

The overturning pressing arm 1 is of a plate-shaped structure and can be connected with various parts conveniently through bolts. The driver 3 may be a swing arm cylinder or the like. The overturning pressing arm 1 is connected with a swing arm of the swing arm cylinder through a bolt.

Referring to fig. 1 and 4, the seat support positioning structure 2 includes a positioning plate 4, a hook 5, a return elastic member 6, and two positioning pins 7. Wherein, the locating plate 4 is vertically connected to the lower surface of the overturning pressing arm 1. The positioning plate 4 comprises a positioning surface 41 and an outer side surface 42. The positioning surface 41 is located at a side of the positioning plate 4 away from the turning press arm 1. The positioning surface 41 is used for positioning and fitting connection with the support body part of the seat support a, as shown in fig. 5.

Referring to fig. 4, the positioning surface 41 has a plurality of magnetic connectors 9 therein, and can be fixed by adhesion. Thus, when the seat support A is positioned on the positioning surface 41, the seat support A can be adsorbed and fixed by the magnetic connecting piece 9, and falling and deflection in the rotation and automatic clamping processes of different areas can be prevented.

Referring again to fig. 4, two locating pins 7 are located on either side of the locating plate 4. The two positioning pins 7 are respectively used for positioning and connecting with the two positioning holes A1 of the seat support A, so that the position of the seat support A is determined, and the seat support A is conveniently and smoothly installed.

Referring again to fig. 4, the hook 5 is rotatably connected to the outer side of the positioning plate 4 through a rotation shaft 11, and the return elastic member 6 is connected between the positioning plate 4 and the hook 5.

The reset elastic piece 6 enables the hook 5 to be kept closed and folded, so that the seat support A can be prevented from falling and shifting in position in the rotating and automatic pressing process, and the installation accuracy of the seat support A is improved.

Referring again to fig. 4, the hooking portion of the hook 5 has a first guide surface 51 and a second guide surface 52 such that the hooking portion forms an approximately triangular structure. The first guide surface 51 and the second guide surface 52 are provided to facilitate hooking and releasing the U-shaped hooks. The first guide surface 51 and the second guide surface 52 are in arc transition connection, so that the U-shaped hook can be prevented from being scratched in the process of hooking the U-shaped hook.

Referring to fig. 5, when the U-shaped hook of the seat bracket a contacts the first guide surface 51 (i.e., the lower side) of the hook 5, the upward pushing force pushes the hook 5 to rotate about the rotation shaft 11 to open; the U-shaped hook continues to move upwards, and when the U-shaped hook of the seat support A moves to the upper side of the hook 5 (above the second guide surface 52), the hook 5 pushes the hook 5 to close and hook tightly by means of the reset elastic piece 6, so that the U-shaped hook is hooked by the hook 5. After the seat support a is welded to the rear floor B, the seat support positioning structure 2 moves upward as a whole, the second guide surface 52 of the hook 5 contacts with the U-shaped hook of the seat support a, the downward pushing force pushes the hook 5 to rotate around the rotating shaft 11 to open, the seat support positioning structure 2 continues to move upward, and the U-shaped hook of the seat support a is separated from the hook 5 to release.
