Abstract
The invention provides an electric locking device which comprises a motor, a worm, a worm gear, a nut and a screw rod. The worm is installed on an output shaft of the motor, the worm gear is in transmission connection with the worm, and the screw rod is in transmission connection with the nut which is connected with the worm gear. The electric locking device further comprises a lower cover, wherein a first locating groove and a second locating groove are formed in the lower cover, and the motor is located through the first locating groove and the second locating groove. According to the electric locking device, the locating accuracy of the motor is high, installation is convenient, stable transmission between the worm and the worm gear is better ensured, errors caused by vibration of a vehicle are reduced, and the electric locking device is flexible to move and cannot be clamped easily.
Description
Technical field
The present invention relates to a kind of electric lock device, particularly a kind of Vehicular turn electric lock device belongs to automobile technical field.
Background technology
Mostly the motion parts of existing Vehicular turn electric lock device, its principle are to utilize mechanical drive that the rotating of motor is converted to stretching out with indentation of dead bolt to move to finish.Specifically on the 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 the nut; at the terminal dead bolt that connects of screw rod; screw rod also can be used as dead bolt; the rotation of nut is converted to the screw rod straight-line motion; thereby drive dead bolt and produce the action of stretching out with indentation; add that lock body protects and the safety that forms; the failure-free electric steering-lock device, wherein mostly the location of motor is simply motor to be placed in the lower cover, not accurate location; from the beginning transmission very large error is just arranged like this; add the vibration of vehicle, so that the easy clamping stagnation of blocking device brings serious potential safety hazard.
Summary of the invention
Problem for the inaccurate clamping stagnation that brings in above-mentioned Vehicular turn electric lock device motor location the object of the present invention is to provide a kind of electric lock device, can effectively prevent clamping stagnation problem in the mechanical drive.
Technical scheme: a kind of electric lock device, 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 screw rod and described nut are in transmission connection, and described worm gear is captiveed joint with described nut, also comprises lower cover, cover under described and be provided with the first positioning groove and the second positioning groove, described motor is by described the first positioning groove and the second positioning groove location.
Described screw rod can be used as dead bolt, also can add in addition dead bolt mechanism.
Owing to adopt two point location principles, the motor accurate positioning solved the problem of transmission accuracy from the transmission source, and this location structure is simple and reliable, is easy to processing, and is easy for installation.
More accurate in order to locate, described the first positioning groove and the second positioning groove are circular arc.
In addition, described the first positioning groove and the second positioning groove can also be V-arrangement, and the V-arrangement positioning groove has the function of automatic aligning, the error that can effectively avoid Vehicular vibration to bring.
Also comprise cushion blocking, described cushion blocking is arranged between described motor and the described lower cover.
Adopt cushion blocking can further reduce the impact that Vehicular vibration brings, better guarantee the motor setting accuracy, guarantee the stability of rotation of worm screw.
Beneficial effect:
Electric lock device provided by the invention, the motor accuracy of positioning is high, is convenient to install, and guarantees that better Worm Wheel System is steady, reduces the error that Vehicular vibration brings, and mechanism's activity is not easy clamping stagnation flexibly.
