Abstract
The utility model provides an automobile locking structure which comprises a motor, a worm, a worm wheel, a nut and a screw rod. The worm is mounted on an output shaft of the motor and is in transmission connection with the worm wheel, and the worm wheel is fixedly connected with the nut which is in transmission connection with the screw rod. The automobile locking mechanism further comprises a guiding block and a lock tongue, a connecting pin enables the guiding block, the lock tongue and the screw rod to be hinged together, and the guiding block comprises a spherical guiding part to enable the guiding block and a guiding groove to be in point contact. The contact area between the guiding block and the guiding groove is improved to reduce friction force, guiding is smoother, and the whole locking structure is not prone to clamping stagnation in the working process.
Description
Technical field
The utility model relates to a kind of automotive locking mechanism, and particularly a kind of motor turning locking mechanism, belongs to automobile technical field.
Background technology
The motion parts of existing motor turning locking mechanism, mostly its principle is to utilize mechanical drive that the rotating of motor is converted to stretching out with indentation of dead bolt to have moved.Specifically on motor output shaft, worm screw is installed, rotation along with motor shaft, thereby worm screw is also rotated and drives worm gear, nested nut on the center shaft of worm gear, screw rod is set in nut, at screw rod end, connect a dead bolt or screw rod as dead bolt, the rotation of nut is converted to screw rod straight-line motion, thereby drive dead bolt to produce the action of stretching out with indentation, additional lock body protects and the safety that forms, failure-free electric steering locking mechanism, wherein, for mechanism smooth and easy, dead bolt needs a guide piece conventionally, but existing guide piece is rectangular blocks normally, its area of contact is large, easily cause clamping stagnation, especially when the resistance of unblanking is larger, dead bolt Chang Yinwei guiding is not just, causing can not release or locking, having a strong impact on vehicle uses.
Summary of the invention
The dead bolt guide piece existing for above-mentioned motor turning locking mechanism causes the problem of dead bolt clamping stagnation, and the purpose of this utility model is to provide a kind of automotive locking mechanism, can effectively prevent clamping stagnation problem in mechanical drive.
Technical scheme: a kind of automotive locking mechanism, comprise motor, worm screw, worm gear, nut and screw rod, described worm screw is installed on the output shaft of described motor, described worm gear is connected with described worm drive, described worm gear is fixedly connected with described nut, and described nut is connected with described screw drive, also comprises guide block and dead bolt, connecting pin is hinged by described guide block, described dead bolt and described screw rod, and described guide block comprises that spherical guide part makes to form point between described guide block and guide groove and contacts.
Middle face contact guiding, contacts at guiding process mid-point because the spherical guide part of use makes described guide block compared to existing technology, and friction force is little, moves more smooth and easy, is not easy clamping stagnation.
Described guide block also comprises cylindrical tail end, and magnet is fixed on described cylindrical tail end, and PCB circuit card is furnished with the first Hall element in the reference position of the described guide block stroke of correspondence, final position is furnished with the second Hall element, and described PCB circuit card is controlled described motor.
Control principle is: when mechanical driving part is carried out described dead bolt and stretched out, described guide block moves up, and when described guide block moves to final position, the second Hall element on described PCB circuit card senses magnetic, control described motor and stop, sending locking settling signal simultaneously; When described dead bolt, retract, when described guide block is got back to reference position, the first Hall element on described PCB circuit card senses magnetic, controls described motor and stops, and sends the settling signal of unblanking simultaneously.
Owing to having increased electrical control, more accurately intelligence, is convenient to realize automatic control.
Described dead bolt is provided with described in runway groove connecting pin and inserts described runway groove and connect described screw rod and described guide block simultaneously, between described screw rod and described dead bolt, be also provided with spring, when described screw rod is stretched out, by described spring, promote described dead bolt and stretch out, during described screw retract, by described connecting pin, pull described dead bolt to retract.
Beneficial effect:
The utility model, by improving the area of contact between guide block and guide groove, reduces friction force, leads more smooth and easy, in whole lockout mechanism working process, is not easy clamping stagnation.
