Description

A kind of unlatching memory mechanism for automobile door lock

Technical field

The utility model belongs to automobile door lock technical field more particularly to a kind of unlatching memory machine for automobile door lock Structure.

Background technique

With the continuous innovation of automotive engineering, more and more high-end products are just gradually market-oriented, wherein automobile door lock Electric opening and electronic actuation are also being received by the majority of consumers, the same with other automatically controlled opening door locks, electric opening All there is a kind of situation in door lock, be exactly after electric control operation can not normally-open car door situation, will lead to it is cumbersome, it is inconvenient In operation, user satisfaction is reduced.

Utility model content

The utility model in order to solve shortcoming in the prior art, provide a kind of structure is simple, security reliability is strong, It operates convenient, the operation is stable the unlatching for automobile door lock and remembers mechanism.

In order to solve the above technical problems, the utility model adopts the following technical solution: a kind of unlatching for automobile door lock Remember mechanism, including pedestal, is rotated coaxially in pedestal by connecting shaft and be connected with opening arms and lock pawl, one on the left of opening arms It is provided with position limit arm, the block positioned at position limit arm upper left-hand is fixedly connected on lock pawl, is fixedly connected with and is located in pedestal Fixed column on the right side of position limit arm lower part is connected with reset spring, fixed company in the middle part of position limit arm between position limit arm lower part and fixed column It is connected to limited post, the snap-gauge being provided with above opening arms in pedestal, snap-gauge is rotatably connected in pedestal by shaft, shaft On be provided with the first torsional spring, snap-gauge side is fixedly connected with the fixture block outwardly protruded, opening arms and lock pawl respectively with snap-gauge card Cooperation is connect, the memory bar being provided with below opening arms in pedestal, memory bar middle part is rotatably connected on pedestal by jackshaft It is interior, the second torsional spring, memory bar right part upside and snap-gauge lower part press fit, memory bar left part downside are provided on jackshaft With press fit on the upside of limited post, memory bar left end downside offers limiting slot, is arranged in pedestal for driving opening arms to rotate Driving device.

The driving device includes the driving motor being fixedly connected in pedestal and is rotatably connected in pedestal and is located at Lead screw on the left of driving motor is equipped with driving gear on the output shaft of driving motor, and lead screw lower part is equipped with and driving gear The driven gear of engaged transmission, lead screw top are threaded with sliding block, and sliding block two sides are slidably connected in pedestal, sliding block and unlatching Arm right part press fit.

The fixture block end is set as arc structure, and memory bar right part is set as bevel structure and forms guide surface.

It is downwardly protrude to form arc groove in the middle part of the opening arms, the arc groove sidewall of opening arms is crimped with shaft side wall matches It closes.

By adopting the above technical scheme, the utility model has the advantages that

1, when automobile door lock is under locking states, opening arms and lock pawl are fastened on snap-gauge the utility model, Bar is remembered under the action of the second torsional spring on jackshaft, so that memory bar left part crimps with the limited post on position limit arm and matches It closes；When starting driving motor, the output shaft of driving motor rotates and drives driving gear and driven gear engaged transmission, so that silk Thick stick rotation, since sliding block is threaded on lead screw, and pedestal limits the freedom degree of sliding rail in a circumferential direction, thus silk Thick stick rotation band movable slider slides axially along lead screw, and sliding block slide downward drives opening arms and position limit arm to turn clockwise around connecting shaft Dynamic, position limit arm drives lock pawl to rotate clockwise around connecting shaft by block, so that lock pawl and snap-gauge are disengaged from, During position limit arm rotates, the limited post on position limit arm acts on memory bar, when position limit arm turns to certain position, limit Column slides into the limiting slot of memory bar, so that position limit arm and memory bar are formed and be clamped, to limit position limit arm and unlatching The position of arm, so that opening arms can not reset under the action of reset spring, at this point, automobile door lock, which is in, opens memory state.

2, when automobile door lock be in open memory state when, snap-gauge under the action of the first torsional spring in shaft, snap-gauge around Shaft rotates clockwise, while snap-gauge drives fixture block to rotate together, and after fixture block and the contact of memory bar right part, fixture block is being rotated During push memory bar to rotate clockwise around jackshaft, fixture block end is set as arc structure, the setting of memory bar right part Guide surface is formed for bevel structure, pushes memory bar to rotate clockwise convenient for fixture block, fixture block pushes memory bar to turn to a positioning When setting, limited post is skidded off out of limiting slot, so that memory bar releases the limitation to position limit arm and opening arms, at this point, limit Arm drives opening arms to rotate counterclockwise and reset under the action of reset spring, at this point, automobile door lock is in the open state.

In conclusion the utility model structure is simple, transfer chain is short, safe and reliable, so that automobile door lock is issuing After open command, even if car door is not normally-open, automobile door lock also can be not necessarily to frequent operation in memory state is opened, practical Property it is strong, have extremely strong promotional value.
