Vehicle electric door lock controller

Abstract

The invention discloses a vehicle electric door lock controller comprising a pedestal, and a drive motor, a worm gear and a swing arm arranged in a corresponding containing room in the pedestal; an output shaft of the drive motor is fixedly provided with a worm rod engaged with the worm gear; one end of the swing arm is positioned on the pedestal through a hinge pin; the other end of the swing arm faces the worm gear; the worm gear rotates to drive the swing arm to rotate back and forth around the hinge pin with certain angel and position; the vehicle electric door lock controller also comprises an elastic piece, an elastic conduction piece and a circuit board; in a swing process of the swing arm, the elastic piece can elastically press against one side of the middle portion of the swing arm; the elastic conduction piece is fixed on the other side of the middle portion of the swing arm; the circuit board is fixed on the pedestal; the elastic conduction piece is in elastic contact with the circuit board for conduction connection. The vehicle electric door lock controller uses pulse power supply to control positive and negative rotation of the motor, can elastically open and close an vehicle electric door lock, thus improving vehicle electric door lock open and close reliability.

Description

[0001] technical field [0002] The invention relates to an automobile circuit door lock control device, in particular to an automobile electric door lock controller. [0003] Background technique [0004] In modern cars, all kinds of central control door locks are widely used. Whether it is a split electric lock with a mechanical lock and a latch, or a central control mechanical integrated electric lock, every car electric door lock is inseparable from the control car. The device for opening and locking the electric door lock, that is, the car electric door lock controller. The car electric door lock controller is generally installed on the car door together with the car door lock. The car electric door lock controller usually includes a motor, a reduction mechanism (such as a turbine and a worm), a circuit board, a contact piece and a casing; at present, the car electric door lock The opening and closing of the car electric door lock controller is mainly realized by the ...

Problems solved by technology

The car electric door lock controller is generally installed on the car door together with the car door lock. The car electric door lock controller usually includes a motor, a reduction mechanism (such as a turbine and a worm), a circuit board, a contact piece and a casing; at present, the car electric door lock The opening and closing of the car electric door lock controller is mainly realized by the forward and reverse rotation of the motor of the car electric door lock controller, but the forward and reverse rotation of the motor in the car electric door lock controller in the prior art needs to use a long-wave pulse power supply, which requires a Time-consuming power-on, resulting in waste of resources

In addition, when opening and closing the electric door lock of the car, the structure of the electric door lock controller is inelastic to open and close, so there is a problem of opening and closing reliability
