Abstract

The utility model relates to an automobile front cover lock double opening mechanism. The automobile front cover lock double opening mechanism comprises a bottom plate, a ratchet wheel, a switch, a pawl, a pawl riveting pivot, a pawl torsional spring, a release arm, a ratchet wheel hollow shaft sleeve, a release arm tension spring, a front cover claw hook and a hollow shaft. When an engine cover is closed, the front cover claw hook pushes the release arm to rotate around the pawl riveting pivot anticlockwise and then pushes the ratchet wheel to rotate around the ratchet wheel hollow shaft sleeve anticlockwise to enable the ratchet wheel to rotate around the pawl riveting pivot to rotate anticlockwise, when the pawl is engaged with the ratchet wheel, the ratchet wheel is in a secondary locking state, and when the front cover claw hook continuously pushes the release arm and the ratchet wheel to rotate anticlockwise, the ratchet wheel reaches a primary locking state. Therefore, the problems of large part quantity and high noise can be solved; due to the fact that a single ratchet wheel has the functions of primary locking and safe locking, the automobile front cover lock double opening mechanism is compact in structure, low in cost, safe and reliable.

Description

The two opening mechanisms of a kind of vehicle front cover lock

Technical field

The utility model belongs to auto parts machinery field, is specifically related to the two opening mechanisms of a kind of vehicle front cover lock.

Background technology

At present automotive engine hood lock all has two-stage lockable mechanism, one-level locking and safe lock, and in prevention driving process, the unexpected safety lock of opening of one-level lock still pins hood and prevents that hood from opening and block pilot's line of vision and cause the accident.Front cover lock one-level locking and safe lock can be divided into two kinds of forms by structure, and a kind of form is that one-level lockable mechanism and safe lock mechanism are all integrated on lock body; Another form is that one-level lockable mechanism is integrated on lock body, and safe lock mechanism is integrated on ratchet.One-level is locked at driver's cabin control and opens, and safe lock is manually opened before vehicle body.

Utility model content

The purpose of this utility model is to provide the two opening mechanisms of vehicle front cover lock that a kind of compact conformation, noise are little.

The technical scheme that realizes the utility model object is: the two opening mechanisms of a kind of vehicle front cover lock, comprise base plate, ratchet, ratchet torsion spring, switch, ratchet, ratchet riveting axle, ratchet torsion spring, release arm, ratchet hollow shaft sleeve, release arm extension spring, protecgulum grapple, hollow shaft; Kill engine while lid, protecgulum grapple promotes release arm and rotates counterclockwise around ratchet riveting axle, then promotes ratchet and rotate counterclockwise around ratchet hollow shaft sleeve, ratchet is rotated counterclockwise, in the time that ratchet engages with ratchet, in secondary latch state around ratchet riveting axle; Protecgulum grapple continues to promote release arm and ratchet rotates counterclockwise, and arrives one-level lock status; In the time that one-level lock is opened, ratchet rotates counterclockwise around ratchet riveting axle, ratchet departs from and engages with ratchet, ratchet clockwise rotates around ratchet hollow shaft sleeve under the effect of ratchet torsion spring, the 2e position of ratchet is hampered by the 5d position of ratchet and no longer rotates, discharge after drag-line, now ratchet clockwise rotates around ratchet riveting axle under the effect of ratchet torsion spring, get back to home position, the 5d position of ratchet departs from the 2e position of ratchet, release arm clockwise rotates secondary latch state around ratchet riveting axle under release arm extension spring effect, and switch becomes off-state from conducting; Ratchet clockwise rotates around ratchet hollow shaft sleeve, and when ratchet engages with ratchet, release arm contacts with protecgulum grapple, and now front cover lock is safe lock state in secondary latch state; In the time that secondary latch is opened, switch still remains open state, and ratchet clockwise rotates around ratchet hollow shaft sleeve, and in the time that ratchet contacts with base plate, release arm contacts with ratchet hollow shaft sleeve, and protecgulum grapple and ratchet disengage, and safe lock is untied, and front cover lock is opened.

Preferably also comprise buffer stopper, described buffer stopper is contained on ratchet, kill engine while lid, first protecgulum grapple contacts with the 8b position on release arm, along with the rotation of ratchet, the 2d position on ratchet promotes the 5c position on ratchet, and ratchet is rotated counterclockwise around ratchet riveting axle, in the time that engage at the 5b position of ratchet and the 2b position of ratchet, in secondary latch state.

Preferably in the time that one-level lock is opened, act on for the first time ratchet is rotated counterclockwise around ratchet riveting axle when the 5a position on ratchet is subject to drag-line, when the 5b position on ratchet departs from and engages with the 2a position on ratchet, ratchet clockwise rotates around ratchet hollow shaft sleeve, when engage with the 5b position on ratchet at the 2b position on ratchet, 8b position on release arm contacts with protecgulum grapple, and now front cover lock is safe lock state in secondary latch state.

It is preferred in the time that secondary latch is opened, 5a position on ratchet is subject to drag-line and acts on for the second time ratchet is rotated counterclockwise around ratchet riveting axle, when the 5b position on ratchet departs from and engages with the 2b position on ratchet, ratchet clockwise rotates around ratchet hollow shaft sleeve, in the time that the 2c position on ratchet contacts with the 1a position on base plate, the 8a position on release arm contacts with the 9a on ratchet hollow shaft sleeve, and protecgulum grapple and ratchet disengage, safe lock is untied, and front cover lock is opened.

The utlity model has positive effect: (1) one-level locking and safe lock function are concentrated and acted on part of ratchet, and ratchet one-level lock position is plastic by elastic body, has reduced the impact noise of closing the door, and has reduced cost, not only comfortable but also hommization.

(2) diverse location on front cover lock ratchet and ratchet engage to realize and one-level locking and the secondary safe lock of snap close; One-level lock and secondary latch by one open handle through secondary opening discharge unlocking action or once for a long time breakdown action realize unlatching; On front cover lock, no longer need two independent level security ratchet and opening handles.

(3) on hood, can assemble two these front cover locks, be formed by master key and secondary lock, master lock band position switch, secondary lock is without position switch; Realize the unlatching of simultaneously controlling two locks by junction box; Protecgulum ratchet is all subject in firsts and seconds lock position unblanking to act on the release arm of the non-Concentric rotation of ratchet, guarantees that car door opening puts in place and reduces the vibrating noise in motion; The function first Application that secondary opening discharges is to front cover lock product.
