Utility model content
The technical problems to be solved in the utility model is: in order to solve the problem, and the utility model provides a kind of motor door lock assembly to solve the problems referred to above.
The utility model solves the technical scheme that its technical problem adopts: a kind of motor door lock assembly, comprise motor, first gear, second gear, 3rd gear, cam, lever, straight spring, dead bolt and torsion spring, the output shaft of described motor is fixedly connected with the first gear, the first described gear and the second gears meshing, the second described gear and the 3rd gears meshing, the 3rd described gear is fixedly connected with cam, the boss of described cam in one end of lever top and one end of lever can be depressed, described straight spring is positioned at the top of the other end of lever and straight spring can be levered up by the other end of lever, described dead bolt has lockhole and groove, one end card of described straight spring in a groove, described dead bolt is provided with torsion spring.
Also comprise base and support, described motor is arranged on base, and the center of the second described gear is provided with the first axle and rack-mount by the first axle, and the center of the 3rd described gear is provided with the second axle and rack-mount by the second axle.
Described lever and straight spring are installed on support.
Described motor is stepper motor.Precision is high, stable.
On described support, corresponding lever has elongated hole upwards near one end place of straight spring.Electrical fault or power-off, open Door by Hand.
The beneficial effects of the utility model are, the utility model motor door lock assembly, and (1) uses stepper motor output torque, driven gear, cam rotate, and cam is pressed in lever one end, and the lever other end tilts, flick straight spring, dead bolt rotates under the drive of torsion spring, realizes the unlatching of door lock.This motor door lock mechanism adopts the transmission of cam, lever and straight spring, is separated by mechanical part with powered part.There is provided coupling mechanism force by mechanical part completely when locking a door, powered part is separated, and improves the reliability of locking a door, also serves effective protection to powered part.This device precision is high, easy to control, effectively raises reliability and the practicality of product.
