Similarly, when the user releases the pressing force, the elastic portion 30 extends to recover the deformation and release energy, so that the button 10 moves towards the side far away from the shell body 40, the movement of the button 10 drives the damping rack 12 to move in engagement with the damping gear 50, a damping force is provided for the button 10, the button 10 slowly moves to the original position under the action of the damping force, and slowly bounces, so that the technology sense is strong, the rebound is slow, no impact noise is generated, and the experience sense is strong. Meanwhile, the button 10 moves to drive the linkage piece 20 to return to the original position, and the limiting block 450 of the shell body 40 returns to the initial end of the limiting groove 110, so that the reset of the button 10 and the linkage piece 20 is realized. In addition, the elastic member 60 is extended to restore the deformation and release energy to move the first and

second locking tongues

71 and 74 in a direction away from the case body 40 while the user releases the pressure, and returns to the original position. The movement of the second latch 74 moves the link 80 in a direction away from the housing body 40, returning to the original position. This glove box lock button 10 locates on the control mechanism, compares prior art with button 10 install on motionless plaque, and it all needs to install a large amount of connection spare parts in plaque and glove box, has reduced a large amount of connection transmission spare parts, and the structure is simpler with the installation, low in production cost, simultaneously, and first spring bolt 71 second spring bolt 74 synchronism is good, multistage linkage, and the performance is excellent. Therefore, the technical problems that the structure is complex, the installation is difficult and the production cost is high in the fixed button 10 type glove box lock are solved.

A second embodiment of the present invention provides a glove box lock, which is substantially the same as the glove box lock in the first embodiment, and is different in that:

in the embodiment, the lock cylinder is additionally arranged in the lock shell, so that the key can be unlocked and locked, and the safety of articles in the glove box and the privacy of a user can be guaranteed. When the key is rotated to lock, the lock cylinder is blocked to prevent the movement of a connecting pin connected with the connecting rod and the linkage piece. When the button is pressed, the connecting pin is blocked from moving, and the first lock tongue 71 and the second lock tongue 74 cannot move out of the lock hole to unlock. When the key is rotated in the direction to unlock, the movement direction of the connecting pin is not blocked, so that the button can control the opening and closing of the glove box lockset. The glove box lock further increases the storage safety through the combined action of the lock cylinder and the button structure, and simultaneously solves the technical problems that the fixed button type glove box lock is complex in structure and difficult to install, and the production cost is high.
