During installation, the connecting groove b1 of the front tripod body is inserted obliquely into the locking wire piece d1 of the vehicle body floor, the seat body 1 is slightly pressed forward, and the tripod locking hook b2 of the front tripod is automatically buckled (that is, it buckles the front locking wire piece d2 of the vehicle body floor); then the seat body 1 is flipped backward and pressed hard, and the locking wire piece d3 behind the vehicle body floor is automatically buckled into the matching position of the rear tripod hook 3b and the notch k1 of the rear connecting body, and finally the backrest is adjusted to the use position, and the seat installation is completed. Disassembly and assembly are simple and quick, and this seat disassembly and assembly design can quickly free up the rear space, increase the luggage compartment space, and make it convenient for the driver to place more items, which is very convenient.

[0034] Furthermore, an anti-misoperation mechanism may be installed in the motor vehicle seat structure. Figure 5 To Attachment Figure 8 The anti-misoperation mechanism includes a driving mechanism 4 and a linkage mechanism 5. The driving mechanism 4 is installed on the rear connecting body 23, and the linkage mechanism 5 is installed on the seat body 1. The driving mechanism 4 and the linkage mechanism 5 are linked and connected by a cable 6.

[0035] Specifically, the driving mechanism 4 includes an anti-foolproof paddle 41 and a spring 42. The anti-foolproof paddle 41 is hinged to one of the connecting plates of the rear connecting body 23. One end of the anti-foolproof paddle 41 is placed in the hook body of the rear tripod hook 3b, and the other end is connected to the cable 6. The cable 6 is arranged through a cable fixing plate 61, and the cable fixing plate 61 is connected to the base frame 2, so that the movement of the anti-foolproof paddle 41 drives the cable 6 to move. In addition, one end of the spring 42 is connected to the anti-foolproof paddle 41, and the other end is connected to the rear connecting body 23, thereby playing a resetting role.

[0036] The linkage mechanism 5 is installed in the seat body 1, and the linkage mechanism 5 includes a seat angle adjustment handle 51, an anti-foolproof lock hook plate 52, an anti-foolproof locking plate 53 and a reset spring 54. The anti-foolproof locking plate 53 is connected to the seat angle adjustment handle 51, and the anti-foolproof locking plate 53 is connected to the shaft pin 51a. The shaft pin 51a is connected to the lower plate 55 of the angle adjuster. When the user adjusts the seat angle adjustment handle 51, it can drive the anti-foolproof locking plate 53 to rotate around the shaft pin 51a; the outer periphery of the anti-foolproof locking plate 53 is protruded with a locking platform 53a. In one embodiment, the locking platform 53a can be a hook-shaped body. State, at the same time, one end of the above-mentioned return spring 54 is connected to the anti-foolproof locking plate 53, and the other end is connected to the anti-foolproof lock hook plate 52; the anti-foolproof lock hook plate 52 and the lower plate 55 of the adjuster are hinged to each other by a rotating pin s1, the anti-foolproof lock hook plate 52 is connected to the other end of the cable 6, and the cable 6 is arranged through a cable fixing bracket 63, and the cable fixing bracket 63 is fixedly connected to the lower plate 55 of the adjuster, and the anti-foolproof lock hook plate 52 is provided with a lock hook groove 52a on the side facing the anti-foolproof locking plate 53, and the lock hook groove 52a can cooperate with the locking platform 53a of the anti-foolproof locking plate to prevent misoperation. When the rear leg of the seat is not installed, the lock hook groove 52a of the anti-foolproof lock hook plate limits the clockwise rotation movement of the locking platform 53a of the anti-foolproof locking plate, and the seat angle adjustment handle 51 cannot be used, and the seat back cannot be adjusted at this time; when the rear leg of the seat structure is locked in place, the locking wire piece d3 behind the vehicle body floor automatically buckles into the matching position of the rear leg hook 3b and the notch k1 of the rear connecting body. At this time, the locking wire piece behind the vehicle body floor drives the anti-foolproof paddle 41 at the rear leg hook to rotate clockwise, and the cable 6 moves downward after being pulled, thereby driving the anti-foolproof lock hook plate 52 to rotate counterclockwise, and the limiting cooperation between the lock hook groove 52a and the locking platform 53a is released, that is, at this time the anti-foolproof locking plate is unhooked, and the seat angle adjustment handle 51 can be used, and the backrest of the seat body can be adjusted by pulling the seat angle adjustment handle 51. The seat structure of the present invention is provided with an anti-misoperation mechanism. When the rear leg lock of the seat is not buckled in place or not buckled, the seat angle adjustment handle of the seat back is blocked by the anti-foolproof lock hook plate, and the backrest angle cannot be unlocked to adjust the seat back angle. If the rear leg lock of the seat is buckled in place, the body lock thread must squeeze the anti-foolproof paddle and then use the cooperation of the driving mechanism, the cable and the linkage mechanism to unlock the backrest angle adjustment handle, so that the backrest angle can be adjusted, thereby preventing the safety hazard of passengers using the seat when the seat is not installed in place and causing an accident. The seat structure of the present invention is safer, more reliable, and very convenient and quick to disassemble.

[0037] The following will be combined with the attached Figures 9A to 9E The loading and unloading process of the present invention is described below.
