Abstract

The invention relates to a main body of door lock of vehicle, which comprises a lock frame, a cover plate, a clamp plate with return spring, a pallet, a pallet spring and a unlock arm. Wherein, the clamp plate is mounted on the rotation axle, while it has claw groove matched with pallet; the pallet is mounted on the rotation axle of pallet; the end of one arm of pallet has the convex claw matched with the claw groove, to compress one end of pallet spring above said arm; another arm of pallet is contacted with unlock arm; when locking, the function force of pallet spring can contact the clamp plate to avoid its rotation; when unlocking, the unlocking arm rotates the pallet, to overcome the force of pallet spring, to release the clamp plate; then the clamp plate will rotate back by the return spring, to unlock. The invention avoids the lock element, internal handle unlocking element, external handle unlocking device and lock pin unlocking element, to simplify the structure.

Description

Every lock main body in the automobile

Technical field

The invention belongs to the lockset technology, be specifically related to the door latch structure of automobile.

Background technology

Automobile door lock is the main anti-theft device of automobile, is the system of reliable locking of control car door and safe opening.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, as shown in Figure 1, 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. have been generally included.Because this kind grille main body structure member is more, required installing space is big.When every is locked in being used in usually, grille main body and external-open, in to open the distance of handle and locking button far away, if will be combined in all common functions on the door lock, then can compare difficulty for the control of door lock, it is complicated that the link gear of all functions also will become.

Therefore, in some slidingtypes among the Men Chemen, 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 objective of the invention is to the problems referred to above of existing at prior art, and the actual needs of cliding door, every lock main body in a kind of automobile is provided, make it can satisfy arrangement requirement in car door, can satisfy the functional requirement of door lock again.

Technical scheme of the present invention is as follows:

Every lock main body in a kind of automobile, 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, only realizing latch functions, every lock agent structure is oversimplified in making, 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 structural representation of former middle every 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 that the middle every that the present invention proposes is locked the structural representation of main body.

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

Below in conjunction with Fig. 2 structure of the present invention is described in detail:

Every lock main body is mainly by forming with lower member in this: 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 25C 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 25C 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, every lock main body in the automobile, it includes lock housing, cover plate, takes back the clamp of a spring, ratchet, ratchet spring and unlocking arm; It is characterized in that: 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 establishes ratchet spring, makes the one end 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.
