Abstract

The utility model relates to a car door lock major structure consisting of a lock shell, a cover slab, a template with retracting spring, a ratchet and a ratchet spring. The template is mounted on the template revolution axis; the ratchet groove on the template matches the ratchet; the ratchet is mounted on the ratchet revolution axis; the dog on the end of one arm of the ratchet matches the ratchet groove on template and press one end of the ratchet spring on the arm; the other arm of the ratchet leans against the unlocking arm. When locking, the template is pressed by the acting force of the ratchet spring to prevent the template from back rotating; when unlocking, the ratchet is stirred by the unlocking arm and rotates, and then overcomes the force of ratchet spring to release template; the template back rotates under the action of retracting spring, thus unlocking realizes. Such lock body has no locking mechanism, inner handle unlocking mechanism, outer handle unlocking mechanism, and core unlocking mechanism, which makes the major lock structure simple, thus the requirement of unlocking is met and the arrangement of door lock is more active.

Description

The grille main body structure of automobile

Technical field

The utility model belongs to the lockset technology, is specifically related to automobile door lock.

Background technology

Automobile door lock is the system of reliable locking of control car door and safe opening, is the main anti-theft device of automobile.It is made up of grille main body, outdoor handle assembly, inner handle assembly, lock ring assembly (or block assembly), lock core assembly and linkage part usually.For grille main body, generally include: lock housing 11, outer handlebar unlocked mechanism 12, Internal handle release mechanism 13, lockable mechanism 14, dead lock 15, lock core release mechanism 16 etc., as shown in Figure 1.Because this kind door latch structure parts are many, required installing space is big, and usually for middle every lock, grille main body and external-open, in to open the distance of handle and locking button far away, then can compare difficulty so all common functions are combined on the door lock control for door lock, it is complicated that the link gear of all functions also will become.

Therefore, in some cliding doors, in order to satisfy the design of car door and miscellaneous part, can design separately grille main body, grille main body only need be realized the car door locking function, be connected with locking switching mechanism then, outward open handle, in drive handle, locking button and dead lock and all be connected and get final product with switching mechanism.

Summary of the invention

The purpose of this utility model is the problems referred to above of existing at prior art, and the actual needs of cliding door, and a kind of automobile door lock agent structure is provided, and makes it can satisfy arrangement requirement in car door, can satisfy the functional requirement of door lock again.

The technical solution of the utility model is as follows:

A kind of automobile door lock agent structure, it is mainly by forming with lower member: lock housing, cover plate, the clamp of taking back a spring, ratchet, ratchet spring and unlocking arm.Clamp is assemblied in the clamp rotating shaft, and the pawl groove with click-fit is arranged on the clamp; Ratchet is assemblied in the ratchet rotating shaft, and the end of an arm of ratchet has dog to cooperate with pawl groove on the clamp, and makes an end of ratchet spring be pressed in the top of this arm, another arm of ratchet and unlocking arm against.When locking, the active force by ratchet spring props up clamp, prevents the clamp revolution; Stir ratchet by unlocking arm during release and rotate, overcome the power of ratchet spring, remove the constraint to clamp, clamp is realized release in the effect turning down of return spring then.Above-mentioned parts all be with the lock housing support assemblies in lock housing, and cover plate is set in lock housing one side, cover above-mentioned parts, be used for sealing the axially-movable of restricted internal part simultaneously of lock body internal construction.

This grille main body has been cancelled lockable mechanism, Internal handle release mechanism, outer handlebar unlocked mechanism and lock core release mechanism, and the grille main body structure is oversimplified, and has both satisfied the requirement of release, can make the layout of door lock more flexible again.

Description of drawings

Fig. 1 is the structure chart of original door lock main body.

Among the figure: 11, lock housing 12, outer handlebar unlocked mechanism 13, Internal handle release mechanism

14, lockable mechanism 15, dead lock 16, lock core release mechanism

Fig. 2 is the grille main body structure chart that the utility model proposes.

Among the figure: 21, lock housing 22, cover plate 23, clamp 24, clamp rotating shaft 25, ratchet

26, ratchet rotating shaft 27, ratchet spring 28, unlocking arm

The specific embodiment

Referring to Fig. 2, this grille main body structure is mainly by forming with lower member: lock housing 21, cover plate 22, the clamp 23 of taking back a spring, ratchet 25, ratchet spring 27 and unlocking arm 28.Clamp 23 is the parts that cooperate with lock pin, is assemblied in the clamp rotating shaft 24, sways and blocks lock pin.Ratchet 25 is assemblied in the ratchet rotating shaft 26, there is a dog arm 25A end of ratchet 25, be used for cooperating with pawl groove 23A on the clamp 23, and above ratchet and arm 25A that pawl groove on the clamp cooperates, be provided with a ratchet spring 27, it is pushed down downwards, and when the need locking, ratchet 25 rotates the dog of arm 25A end is sticked among the pawl groove 23A, and prop up clamp 23 by the active force of ratchet spring 27, clamp 23 can't be rotated and locking; Another arm 25B of ratchet 25 then leans with unlocking arm 28, rotates to stir ratchet 25 by unlocking arm 28 when the release, overcomes the power of ratchet spring 27, removes the constraint to clamp 23, makes clamp 23 in the effect of return spring next time then release.Above-mentioned each parts all are assemblied in the lock housing 21, are supported by lock housing 21, in the lock housing side cover plate 22 are set simultaneously, cover on the lock body inner body, are used for sealing the axially-movable of restricted internal part simultaneously of lock body internal construction.

Claims

1, a kind of automobile door lock agent structure is characterized in that: it includes lock housing, cover plate, takes back the clamp of a spring, ratchet, ratchet spring and unlocking arm; Described clamp is assemblied in the clamp rotating shaft, and the pawl groove with click-fit is arranged on the clamp; Ratchet is assemblied in the ratchet rotating shaft, and the end of an arm of ratchet has dog to cooperate with pawl groove on the clamp, and makes an end of ratchet spring be pressed in the top of this arm, another arm of ratchet and unlocking arm against; Above-mentioned parts all be with the lock housing support assemblies in lock housing, and cover plate is set in lock housing one side, cover above-mentioned parts.
