Abstract
The utility model relates to a theft-proof lock, in particular to a theft-proof lock for a brake drum of an electric vehicle. The theft-proof lock for the brake drum of the electric vehicle comprises a drum brake main body arranged on a main shaft of a motor, wherein a brake drum is arranged on the drum brake main body; a plurality of lock holes are formed on the inner wall of the brake drum; a driving wheel is arranged on the main shaft; the driving wheel is connected with an eccentric wheel; the eccentric wheel is rotationally connected with the drum brake main body through a shaft, a bidirectional energy storage spring is arranged on the shaft, one end of the bidirectional energy storage spring is connected to the eccentric wheel, and the other end of the bidirectional energy storage spring is connected with a lock pin; and the lock pin is arranged in a chute of a lock pin shell. According to the theft-proof lock, the bidirectional energy storage spring is compressed and released by controlling positive and negative rotation of the motor to realize locking and unlocking; and when the lock pin is attached to the wall of the lock holes, the bidirectional energy storage spring stores energy due to the rotation of the motor, and when the vehicle rocks lightly, the motor is not required to be driven all the time, so the theft-proof lock is convenient to use and the service life of the motor is prolonged.
Description
Technical field
The utility model relates to a kind of anti-theft column lock, relates in particular to a kind of electric vehicle brake drum anti-theft column lock.
Background technology
At present, existing electrocar anti-theft lock is all generally outer lock or the common magnetic brake lock etc. of joining.These anti-theft column locks are all outside exposed basically, be easy to be pried open by the robber, and lockhole easily advance silt, cause key not open and the drawback such as inconvenient operation, thereby cause battery-driven car often stolen, bring very large economic loss and worry to the car owner.In order to solve the above problems, people have invented a novel built-in anti-theft column lock, this anti-theft column lock rotates to realize that by remote-control motor lock pin movement realizes unblanking and locking, the lockpin ventilating of this anti-theft column lock is crossed a pipe link and is connected on electric machine main shaft, the tail end of lock pin is connected with the root spring, and the other end immediate roof of spring is on the lock housing body; During locking, lock pin penetrates the lockhole that is arranged on brake drum, and when unblanking, by electric machine rotation, the band moving cam is pushed down pipe link lock pin is pulled out lockhole; After locking generally lock pin can and the lockhole wall fit together, so when remote-control motor rotates, due to lock pin and lockhole wall paste tighter, lock pin is stuck in lockhole, ceaselessly rock the release of car ability when need to pin remote controller always, although so realized anti-theft feature, use very inconvenient.
Summary of the invention
In order to address the above problem, the utility model provides a kind of simple in structure, bulging anti-theft column lock of electric vehicle brake that safety performance is high and easy to use.
to achieve these goals, the utility model is mainly solved by the following technical programs: a kind of electric vehicle brake drum anti-theft column lock, comprise drum on the main shaft that the is arranged on motor main body of stopping, rouse the main body of stopping and be provided with brake drum, the inwall of brake drum is provided with several lockholes, the main shaft of described motor is provided with driving wheel, the driving wheel connecting eccentric wheel, eccentric wheel is rotationally connected by axle and the bulging main body of stopping, described axle is provided with the bidirectional energy-storage spring, one end of bidirectional energy-storage spring is connected on described eccentric wheel, an other end of bidirectional energy-storage spring is connected with lock pin, this anti-theft column lock also comprises the lock pin shell, the lock pin shell is provided with chute, be provided with described lock pin in chute.
As preferably, above-mentioned driving wheel is cylindrical wheel, and described eccentric wheel is and described cylindrical wheel mesh sector gear.
The utility model compresses and discharges the bidirectional energy-storage spring by controlling motor positive and inverse, realizes that the locking and unlocking is carried out in the lifting of lock pin; When lock pin and lockhole wall occurring and be close to, because electric machine rotation makes the bidirectional energy-storage spring energy-storage, when slight rolling motor-car, do not need drive motor always, so the utility model is easy to use, and extended life-span of motor.And in a single day utility model has locked, except the drive motor release, unless braking mechanism is removed, otherwise can't release.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing 1, the specific embodiment of the technical solution of the utility model is described in further detail.
Embodiment: a kind of electric vehicle brake drum anti-theft column lock, comprise drum on the main shaft 11 that is arranged on motor 3 main body 1 of stopping, the drum main body 1 of stopping is provided with brake drum 2, and the inwall of brake drum 2 is provided with several lockholes 8.Motor 3 can connect control circuit, coordinates to come drive motor 3 main storys and counter-rotating by remote controller and control circuit.
The main shaft 11 of motor 3 is provided with driving wheel 4, driving wheel 4 connecting eccentric wheels 5, and eccentric wheel 5 is rotationally connected with rousing the main body 1 of stopping by axle 6, and driving wheel 4 is cylindrical wheel, and eccentric wheel 5 is and described cylindrical wheel mesh sector gear; Driving wheel 4 also can be connected to be with movable eccentric wheel 5 to rotate by belt pulley and eccentric wheel 5.
Axle 6 is provided with bidirectional energy-storage spring 7, one end of bidirectional energy-storage spring 7 is connected on described eccentric wheel 5, and an other end of bidirectional energy-storage spring 7 is connected with lock pin 9, and this anti-theft column lock also comprises lock pin shell 12, lock pin shell 12 is provided with chute 10, is provided with described lock pin 9 in chute 10.
When motor 3 main storys or counter-rotating, driving wheel 4 rotation band movable eccentric wheels 5 make 7 energy storage of bidirectional energy-storage spring stir lock pin 9 insertions and break away from lockhole 8 and realize the locking and unlocking.
