Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile trunk locks, in particular to an automobile trunk lock. Background Art
[0002] The trunk of a car is usually locked by a lock body fixed on the trunk door and a lock buckle fixed on the car body. When the trunk is closed, the lock tongue on the lock body will act with the lock buckle. After the car door is completely closed, the lock tongue will return to its position, so that the lock tongue and the lock buckle are locked, thereby achieving the effect of closing the trunk.
[0003] Many car trunk locks will make loud noises when opening and closing the trunk when they collide with the lock tongue, affecting the use effect. Utility Model Content
[0004] The utility model aims to solve the disadvantage that many car trunk lock buckles will make a lot of noise when opening and closing the trunk when colliding with the lock tongue, thus affecting the use effect, and proposes a car trunk lock.

[0006] A car trunk lock comprises a trunk hook plate and a trunk cover, wherein a lock catch is installed on the top of the trunk hook plate, a notch is opened on the inner side of the trunk cover, a sensor is embedded on the top inner wall of the notch, a cavity is arranged on the trunk cover, an automatic locking mechanism is arranged in the cavity, and a push switch is arranged on the bottom side of the trunk cover; the push switch can manually control a stepping motor so that a locking rod leaves the lock catch and the trunk cover can be opened.
[0007] Preferably, the automatic locking mechanism includes an elastic plate, a locking rod is fixedly installed on the right side of the elastic plate, a sliding hole is opened on the inner wall of the cavity, the locking rod is slidably connected to the inner wall of the sliding hole, the locking rod is adapted to the lock buckle, two sliding rods are fixedly installed on the inner wall of the cavity, and the elastic plate is slidably installed on the outside of the two sliding rods; the bottom end of the lock buckle is inclined.
[0008] Preferably, a plurality of springs are fixedly mounted on the left side of the elastic plate, and the plurality of springs are fixedly mounted on the inner wall of the cavity; the springs provide reset for the elastic plate.
[0009] Preferably, a stepper motor is installed on the top inner wall of the cavity, and an eccentric wheel is installed on the output shaft of the stepper motor, and the eccentric wheel conflicts with the elastic plate; when the eccentric wheel rotates 90 degrees, the eccentric wheel squeezes the elastic plate to move, and the elastic plate drives the locking rod to shrink and avoid the lock buckle, so that the lock buckle will not collide with the locking rod and make noise when the trunk lid is closed.
[0010] Compared with the prior art, the advantages of the utility model are:
[0011] This solution closes the trunk lid. When the lock rod is about to approach the lock buckle, the sensor detects the lock buckle, and the stepper motor drives the eccentric wheel to rotate 90 degrees. The eccentric wheel squeezes the elastic plate to move, and the elastic plate drives the lock rod to shrink and avoid the lock buckle. When the trunk lid is closed, the lock buckle will not collide with the lock rod and make noise;
[0012] The stepper motor of this solution continues to rotate 90 degrees, so that the eccentric wheel leaves the elastic plate, and the spring provides elastic force to the elastic plate. The elastic plate drives the lock rod into the lock buckle, which can fix the trunk lid. Pressing the switch can manually control the stepper motor, so that the lock rod leaves the lock buckle, and the trunk lid can be opened;
[0013] When the utility model closes the trunk lid, the lock rod is retracted to avoid the lock buckle, so that the lock buckle will not collide with the lock rod to produce noise, and the use effect is good. BRIEF DESCRIPTION OF THE DRAWINGS
