[0020] A lock body 11, wherein the lock body 11 has an insertion portion, and the insertion portion is adapted to the lock plug-in structure 3 provided on the chair back;

[0021] A first connecting member 12, wherein the first connecting member 12 is fixedly connected to the lock body 11, the insertion portion extends out of the edge of the first connecting member 12, the first connecting member 12 is provided with at least one first mounting hole, and the first connecting member 12 is detachably connected to the vehicle body bracket 2 through the at least one first mounting hole;

[0022] When the first connecting member 12 is connected to the vehicle body bracket 2, the inserting portion faces the locking and plugging structure 3 provided on the seat back, and the seat back can move until the inserting portion is inserted into the locking and plugging structure 3 to lock the seat back.

[0023] The lock body 11 includes an insertion portion, which is adapted to the lock plug-in structure 3 provided on the seat back, so that after the insertion portion is inserted into the plug-in structure 3, it can be locked with the seat back.

[0024] In some embodiments, the insertion portion is adapted to the locking plug-in structure 3, including the shapes of the insertion portion and the locking plug-in structure 3 being adapted so that after the insertion portion is inserted into the locking plug-in structure 3, it can be clamped with the plug-in structure 3.

[0025] In other embodiments, the insertion portion is adapted to the locking plug-in structure 3, and also includes the insertion portion being a hook structure, a protruding fixing mechanism 31 being provided in the plug-in structure 3, and after the insertion portion is inserted into the plug-in structure 3, it is hung on the fixing mechanism 31, thereby achieving locking of the chair back.

[0026] The first connector 12 is fixedly connected to the lock body 11, for example, by welding. The insertion portion extends beyond the edge of the first connector 12 so that the insertion portion can be better inserted into the lock plug-in structure 3. The first connector 12 is provided with at least one first mounting hole, and the first connector 12 is detachably connected to the vehicle body bracket 2 through at least one first mounting hole. The detachable connection includes screw connection, etc. Taking screw connection as an example, a third mounting hole corresponding to the first mounting hole is provided on the vehicle body bracket 2, and a bolt can pass through the first mounting hole and the third mounting hole, and a bolt connection is achieved after being tightened with a nut.

[0027] In the embodiment of the present application, by setting the structure of the lock 1 as above, the first connecting member 12 fixedly connected to the lock body 11 can be detachably connected to the vehicle body bracket 2 through at least one first mounting hole, so that it is easy to install and disassemble the lock to adapt to different seat structures.
