Problems solved by technology

[0002] The electric tailgate lock of the prior art will be affected by the temperature. When the temperature exceeds 80°C or lower than -40°C, it is easy to cause the lock to fail; in addition, when the tailgate lock of the prior art is in the unlocked state, The pawl linkage arm will be axially offset. At this time, the limit of the pawl linkage arm and the limit of the worm gear will change from line to surface contact to surface to surface contact, which is prone to lockup; when locking again, the pawl will The linkage arm cannot be disengaged and cannot be moved to the full lock position

Abstract

The invention discloses a self-attraction tail door lock. A U-shaped notch is formed in a face board of a lock body, side plates are arranged on the periphery of the face board, the upper end surfaceof the side plate a is provided with a step surface with a gradient, a pawl shaft is arranged on the left side of the U-shaped notch, a pawl is arranged on the pawl shaft, a pawl releasing arm is arranged on the right side of the pawl, a pawl linkage arm is connected with the pawl, and the tail end of the pawl linkage arm is arranged on the step surface of the side plate a. A ratchet shaft is arranged on the right side of the U-shaped notch, a ratchet is arranged on the ratchet shaft, the ratchet is meshed with the pawl, a gear is arranged in front of the pawl shaft, a cam is arranged above the gear, the cam is in contact with the pawl linkage arm, a worm is connected to the left end of a motor, the worm is meshed with the gear, a locking rocker arm is arranged in left front of the ratchet, a push plate is connected with the locking rocker arm and is in contact with the ratchet, and the locking rocker arm is connected with an external actuator. The lock is compact in structure, small in size, good in transmission effect, good in stability, complete in function, and capable of realizing the self-attraction function and the pawl releasing function.

Description

technical field [0001] The invention relates to the field of tailgate locks, in particular to a self-priming tailgate lock. Background technique [0002] The electric tailgate lock of the prior art will be affected by the temperature. When the temperature exceeds 80°C or lower than -40°C, it is easy to cause the lock to fail; in addition, when the tailgate lock of the prior art is in the unlocked state, The pawl linkage arm will be axially offset. At this time, the limit of the pawl linkage arm and the limit of the worm gear will change from line to surface contact to surface to surface contact, which is prone to lockup; when locking again, the pawl will The linkage arm cannot be disengaged and cannot be moved to the fully locked position. Contents of the invention [0003] The object of the present invention is to provide a self-priming tailgate lock with compact structure, reasonable design and good transmission effect; the above technical problems are solved.
