Description

Lock mechanism for automobile glove box

Technical Field

The utility model belongs to the technical field of automobile parts's technique and specifically relates to a latch mechanism for car glove box is related to.

Background

The glove box is an important storage space on an automobile, and the use frequency is extremely high. The glove box is provided with a glove box lock for controlling the opening and closing of the glove box. The service life of the glove box lock directly influences the service life of the glove box, and the service life of the glove box can be greatly shortened if the structural design of the glove box lock is unreasonable. The glove box lock used on the glove box generally adopts a double-sided lock at present, the glove box lock with a simpler structure mainly presses the thumb wheels simultaneously through a handle to drive the two-end lock rod linkage, and the two thumb wheels are meshed together to control the opening and closing of the glove box. The problem that the lock tongues on two sides are not synchronous easily occurs in the structural form of the glove box lock, so that multiple unlocking steps are needed during unlocking, and the use stability and comfort of the glove box are affected.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned problem among the prior art, the utility model provides a latch mechanism for car glove box, when its aim at solved glove box lock and opened and close, the asynchronous problem of spring bolt on both sides.

The technical scheme of the utility model is that:

a lock mechanism for an automobile glove box comprises a handle connected with a glove box cover, wherein a lock seat is fixed in the center of the handle; a cylindrical cavity is formed in the lock base, a bolt connecting disc is rotatably connected in the cavity, and a return spring for driving the bolt connecting disc to rotate is further arranged in the cavity; the lock base is slidably connected with a left lock tongue and a right lock tongue which can slide horizontally relatively, the near ends of the left lock tongue and the right lock tongue are rotatably connected on the lock tongue connecting disc, and the connecting points are symmetrical about the circle center of the lock tongue connecting disc; the spring bolt connection pad is opened and is had the spacing groove of U type, is fixed with the fixture block that stretches into the spacing groove on left spring bolt or the right spring bolt, and the side of spacing groove is the circular arc, and is concentric with the spring bolt connection pad.

Furthermore, the handle is rotatably connected with a vertical rotating shaft, a handle is fixed on the rotating shaft, a push block is further arranged on the rotating shaft, and a pillar which is abutted against the push block is further fixed on the left spring bolt or the right spring bolt.

The pillar is pushed through the rotation of the handle and the push block, so that the left and right sliding of one lock tongue is driven, the lock tongues on two sides can move simultaneously by utilizing the lock tongue rotating disc, and the locking or unlocking is completed.

Further, a sealing ring is arranged between the bolt connecting disc and the lock seat.

The sealing ring is arranged to prevent dust from entering the inside of the lock seat to block the lock seat and cause the lock tongue connecting disc to be clamped; meanwhile, the sealing ring can reduce friction between the spring bolt connecting disc and the lock base, so that the spring bolt connecting disc is easier to rotate.

Furthermore, the middle sections of the left spring bolt and the right spring bolt are both bent downwards, and the bent end parts are positioned on the same horizontal line.

The lock seat can be arranged at the position above the glove box cover, so that a user can conveniently hook the handle; and the end parts of the lock tongues on the two sides for locking are positioned on the same horizontal line, so that the stress of the box cover is more balanced, and the shaking is prevented in the locking process of the box cover.

Further, the end surfaces of the left bolt and the right bolt are arc-shaped.

The friction between the lock tongue and the glove box lock cylinder can be effectively reduced by the arc-shaped surface.

Compared with the prior art, the beneficial effects of the utility model are that:

1. in this scheme, the shrinkage when utilizing circular shape spring bolt connecting seat to make left spring bolt and right spring bolt remove is unanimous, realizes the synchronization of spring bolt, accomplishes one-step unblock, avoids appearing many times the unblock step and could accomplish the unblock, influences stability and the travelling comfort that the glove box used.

2. According to the scheme, after the lock mechanism is unlocked, the bolt connecting disc is driven to rotate by a return spring, so that the left and right bolts are pushed to be locked quickly and conveniently; meanwhile, the return spring is more stable to drive and has low noise.

3. In this scheme, utilize spacing groove and fixture block cooperation, inject the indentation volume of spring bolt, prevent that the spring bolt indentation volume is too big, lead to the torsion transition of return spring, elasticity reduces, the gyration of unable drive spring bolt connection pad.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

The utility model discloses a reference numeral in the description drawing includes: the handle 1, the lock seat 2, the return spring 3, the spring bolt connection disc 4, the sealing ring 5, the left spring bolt 6, the right spring bolt 7, the rotating shaft 8, the handle 9, the push block 10, the pillar 11, the limiting groove 12 and the clamping block 13.

The embodiment is basically as shown in the attached figures 1 and 2:

a lock mechanism for an automobile glove box comprises a handle 1 connected with a glove box cover, wherein a lock seat 2 is fixed at the center of the handle 1; a cylindrical cavity is formed in the lock base 2, a circular bolt connecting disc 4 is rotatably connected in the cavity, a sealing ring 5 is arranged between the bolt connecting disc 4 and the lock base 2, and a return spring 3 for driving the bolt connecting disc 4 to rotate is further arranged in the cavity; the lock base 2 is slidably connected with a left lock tongue 6 and a right lock tongue 7 which can slide horizontally relatively, the right end of the left lock tongue 6 and the left end of the right lock tongue 7 are both rotatably connected to a lock tongue connecting disc 4, the connecting points are symmetrical about the circle center of the lock tongue connecting disc 4, the middle sections of the left lock tongue 6 and the right lock tongue 7 are both bent downwards, the bent end parts are positioned on the same horizontal line, and the end surface of the left lock tongue 6 and the end surface of the right lock tongue 7 are arc-shaped; a U-shaped limiting groove 12 is formed in the bolt connecting disc 4, a clamping block 13 extending into the limiting groove 12 is integrally formed on the right bolt 7, and the side edge of the limiting groove is an arc concentric with the bolt connecting disc 4; the handle 1 is rotatably connected with a vertical rotating shaft 8, a handle 9 is fixed on the rotating shaft 8, a push block 10 is further arranged on the rotating shaft 8, and a support 11 which is abutted against the push block 10 is further welded on the left lock tongue 6.

In the specific implementation:
