Embodiment Construction

[0014] The following combination figure 2 The structure of the present invention is described in detail:

[0015] The main body of the middle door lock mainly consists of the following parts: a lock housing 21, a cover plate 22, a clamping plate 23 with a return spring, a pawl 25, a pawl spring 27 and an unlocking arm 28. The clamping plate 23 is a part that cooperates with the lock pin, and is assembled on the clamping plate rotating shaft 24, and rotates around the axis to clamp the lock pin. The ratchet 25 is assembled on the ratchet rotating shaft 26, and an arm 25A end of the ratchet 25 has a protruding pawl 25C, which is used to cooperate with the claw groove 23A on the clamp plate 23, and cooperates with the claw groove on the clamp plate There is a pawl spring 27 above the arm 25A, which is pressed down. When it needs to be locked, the pawl 25 rotates so that the protruding pawl 25C at the end of the arm 25A snaps into the pawl groove 23A and passes through the pawl ...

Abstract

The invention relates to a main body of door lock of vehicle, which comprises a lock frame, a cover plate, a clamp plate with return spring, a pallet, a pallet spring and a unlock arm. Wherein, the clamp plate is mounted on the rotation axle, while it has claw groove matched with pallet; the pallet is mounted on the rotation axle of pallet; the end of one arm of pallet has the convex claw matched with the claw groove, to compress one end of pallet spring above said arm; another arm of pallet is contacted with unlock arm; when locking, the function force of pallet spring can contact the clamp plate to avoid its rotation; when unlocking, the unlocking arm rotates the pallet, to overcome the force of pallet spring, to release the clamp plate; then the clamp plate will rotate back by the return spring, to unlock. The invention avoids the lock element, internal handle unlocking element, external handle unlocking device and lock pin unlocking element, to simplify the structure.

Description

technical field [0001] The invention belongs to lock technology, and in particular relates to a door lock structure of an automobile. Background technique [0002] The car door lock is the main anti-theft device of the car, and it is a system that controls the reliable locking and safe opening of the car door. It usually consists of a door lock body, an outer handle assembly, an inner handle assembly, a lock ring assembly (or block assembly), a lock cylinder assembly and linkage components. For the door lock body, such as figure 1 As shown, it generally includes a lock case 11, an outer handle unlocking mechanism 12, an inner handle unlocking mechanism 13, a locking mechanism 14, a stopper 15, a lock cylinder unlocking mechanism 16, and the like. Since there are many main structural parts of this kind of door lock, the required installation space is large. When it is usually used on the middle door lock, the distance between the main body of the door lock and the outward ...
