Abstract

The utility model relates to an electrically operated directional lock for steering mechanism of automobiles, using a motor for driving a slide block to move front and back. A locking tong handle is pushed to open or close the locking jaw of the driving rod of an embracing steering machine; a controller which is installed on the casing of a directional lock is used for controlling the motor; the controller can be manually control or remote controlled. The utility model is simple structure, convenient operation, safe operation and high anti-theft performance.

Description

Electrodynamic type automobile steering lock

The utility model belongs to the mechanical ﹠ electrical technology field, is a kind of direction lock of automobile mechanical steering box.

At present, operating direction dish anti-theft column lock easily is damaged, and makes the anti-theft of automobile poor.

The purpose of this utility model is to provide a kind of performance safe and reliable, easy to use, is difficult for opening or dented cars direction lock.

Solution of the present utility model is to adopt the driven by motor slide block to seesaw, and promotion lock pincers handle will be held the lock jaw of steering box drive link tightly and open or closure, and the controller on the installation direction lock shell is controlled motor, and controller can manually be controlled or remote control.

The utility model is simple in structure, and is easy to operate, safe and reliable, and anti-theft is strong.

Below in conjunction with accompanying drawing the utility model is specified:

Fig. 1 looks cutaway view for the utility model master;

Fig. 2 is the utility model side-looking partial cutaway diagrammatic sketch;

Fig. 3 is controller circuitry figure.

Screw mandrel 3 is housed on the output shaft of motor 1, screw mandrel 3 overcoat slide blocks 4, screw mandrel 3 and slide block 4 screws thread fit, respectively there is a lock pincers handle 5 slide block 4 both sides, there is V-shaped part 7 lock pincers handle 5 inboards, be installed with lock pincers pin 6 on the lock pincers handle 5, lock pincers pin 6 is fixed on the shell 2, lock pincers handle 5 front ends have lock jaw 8, and there are teeth 9 lock jaw 8 inboards, and lock jaw 8 surrounds automobile steering device drive link 10, be fixed with controller 11 on the shell 2, slide block 4 tops are fluted 13, controller 11 stir double-throw switch 12 in groove 13, a that stirs double-throw switch 12 in controller 11 ₁Point power connection positive pole, a ₂Point connects control line 13, and passes through the normal opened contact J of relay J _kConnect power cathode, b ₁Point and c ₂ Point connection motor 1 positive pole, b ₂And c ₁The negative pole of some connection motor 1, relay J is attempted by on the motor 1.Need open direction when lock, adopt manually or remote control is joined control line 13 and power cathode once, relay J energising, J _kPoint is closed, and motor is just changeing, and screw mandrel 3 rotates and makes slide block 4 to sinciput V-shaped part 7, will lock jaw 8 to open, and the relay outage discharges, and makes motor 1 stall, and simultaneously, because slide block 4 moves ahead, groove 13 is moved and stirred double-throw switch 12, a ₁Point and c ₁Point connects, a ₂With c ₂Point connects, and when needing locking steering box drive link 10, control line 13 and power cathode is joined once, motor 1 counter-rotating, and slide block 4 is to pusher V-shaped part 7, and lock jaw 8 closures are stirred with double-throw switch 12 a ₁With b ₁Connect c ₂Point and b ₂Connect.

Claims
