Description

Automobile front cover plate lock

Technical Field

The utility model relates to an automobile parts field, concretely relates to car front shroud lock and lockpin.

Background

The automobile front cover plate lock is used for locking and unlocking the automobile front cover plate. The front panel must have two stages of unlocking as required by the legislation. For the structure needing to be manually opened on the front cover plate, the common method at present is to pull open and release the first-stage locking in the passenger compartment and then manually release the second-stage locking in the front of the front cover plate. The traditional secondary locking mechanism is a rotatable hook specially arranged on the lock body, and the hook and the lock body provide resetting force through a torsion spring to ensure secondary locking.

As shown in fig. 1, the conventional front cover plate locking mechanism includes a front cover lock body 100 and a secondary locking hook 200, the secondary locking hook 200 is connected to the lock body 100 by a pin riveted to the front cover lock body 100, and a front cover lock pin 300 is welded to a front cover lock pin base 400. Due to the adoption of the lock body with the structural form, the front cover lock body is complex in structure because the hook 200 for secondary locking is connected; and the hook 200 of the second-stage locking is an independent part, so that the production cost is increased, and the assembly is time-consuming and labor-consuming.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a problem to current front shroud lock body structure complicacy provides a car front shroud lock and lockpin.

In order to achieve the above object, the present invention provides the following technical solutions:

a lock for a front cover plate of an automobile comprises a lock body, wherein a lock hook is formed on one side wall of a U-shaped groove of the lock body; the lock pin base is movably connected with a lock pin in a shape like a Chinese character 'ji', the lock pin is hinged on the lock pin base through two far ends in the shape like the Chinese character 'ji', and a torsion spring used for keeping the middle part of the lock pin clamped in the lock hook is arranged between the lock pin and the lock pin base.

The utility model discloses an in the scheme, increase the latch hook on the U-shaped fluting lateral wall on the lock body, latch hook and lock body stamping forming as an organic whole make the latch hook form on the inherent structure of original component. The lock pin arranged on the lock pin base can be matched with the lock hook through the control of the torsion spring to meet the functional requirement of secondary locking; when the secondary locking state needs to be released, the lock pin is only required to be rotated to be separated from the lock hook.

Under the condition of realizing the function of secondary locking, the scheme has simple structure, only adopts the matching of the lock body and the lock pin, does not need to additionally increase a hook member and related assembly procedures, and saves the production cost and the labor cost; compared with the traditional front cover plate lock, the front cover plate lock of the scheme has the advantage that the whole weight is reduced by about 1/4.

Furthermore, the lock pin is formed by bending a round bar, and at least one end of the lock pin extends out of the lock pin base.

Furthermore, the end part of the lock pin extending out of the lock pin base is provided with a transversely extending handle.

An automobile comprising the automobile front shroud lock of any one of the preceding.

In this scheme, lockpin round bar bending type takes shape, and the assembly method with the lockpin base is articulated, compares in installing through the welded mode, and the lockpin installation of this scheme is more convenient, reduces welding pollution. The lock pin is rotated by the handle extending out of the lock pin base to be separated from the lock hook, so that the purposes of quick unlocking and labor saving are achieved.

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

1. the front cover plate lock of the scheme cancels a second-stage locking hook of an independent component, achieves a second-stage locking function by arranging the locking hook matched with the locking pin on the lock body, and is simple in structure, the whole weight of the front cover plate lock is relatively lightened by 1/4, and the production cost is reduced.

2. The assembly mode of lockpin and lockpin base is articulated, simple to operate, reduces after-sale cost of maintenance and the degree of difficulty.
