The specific embodiment:

Now in conjunction with the accompanying drawings and embodiments the utility model is done and is described in further detail:

Embodiment 1: such as Fig. 1, shown in 2, the present invention includes the negative and positive locker 1 of locking vehicle steering, 2, be fixed on the bearing circle locating bar 3 on the positive locker 2, its special feature is that the clamp holder afterbody 6 of cloudy locker 1 is rotatably connected on the clamp holder 5 of positive locker 2 by rotating shaft 4, the clamp holder afterbody 6 of corresponding cloudy locker 1 is provided with worm screw 7 turbines 8 that driven by actuating unit on the clamp holder 5 of positive locker 2, be provided with gear 8a on the turbine 8, be provided with the tooth 6a with gear 8a engagement on the clamp holder afterbody 6 along rotating shaft 4 axle center, actuating unit comprises micro-computer controlling apparatus 9, motor 10 by micro-computer controlling apparatus 9 controls, motor 10 drives worm screw 7 and rotates, microcomputerized control 9 devices comprise micro controller system 9a, trigger circuit 9b, switch circuit 9c, battery 9d, current-limiting circuit 9e, the electric signal output of trigger circuit 9b links to each other with the electric signal input of micro controller system 9a, electricity output and the trigger circuit 9b of battery 9d, switch circuit 9c, micro controller system 9a links to each other, motor 10 is by current-limiting circuit 9e, switch circuit 9c links to each other with micro controller system 9a, and trigger circuit 9b is the cipher trigger circuit, or by the infrared secret code transmission circuit, infrared ray trigger circuit that the infrared secret code acceptor circuit consists of or by the ID card reader, the ID card trigger circuit that consist of with the ID card of encrypted message, or by the IC card reader, the Contact Type Ic Card circuit that consists of with the IC-card of encrypted message.Trigger circuit are supplied the power supply of positive and negative two directions by the control micro-computer controlling apparatus to motor, the control motor is worked in setting-up time, make motor pass through the moving negative and positive locker forward of cingulum or the counter-rotating of worm screw turbine and clamp holder afterbody, the negative and positive locker is opened or clamping.

Embodiment 2: shown in Fig. 3,4, the present invention is one section circular arc along the set tooth 6a in rotating shaft 4 axle center and distributes on clamp holder afterbody 6 on the basis of embodiment 1, cloudy locker 1 on the clamp holder 5 of positive locker 2 is provided with touch switch 11 through the place, and the electric signal output of touch switch 11 links to each other with the input of micro controller system 9a signal.Be provided with torque spring 12 at cloudy locker 1 and 4 of rotating shafts.

Here, be provided with driving lever 13 at cloudy locker 1.

As shown in Figure 5, by torque spring, in case take departure direction dish, cloudy locker will automatically continue to open to flat position of opening, reduce that cloudy locker collides object in other cars and the damage that causes to handle lock after unblanking.(the power description of operation:

1. entirely open when lock, cloudy locker is remained on the full open position of coupler by torque spring, and this moment, driving lever 13 gears were inner at positive locker.

2. the cloudy locker locker that faces south is drawn close when not triggering trigger switch, power by the lock gravity provide, be placed on lock on the bearing circle after, be locked under the Action of Gravity Field, lock freely falls and by bearing circle top driving lever 13, driving lever 13 rotates along rotating shaft 4 and drives simultaneously cloudy locker rotation.

3. after trigger switch 11a touches single chip machine controlling circuit, the control of micro controller system catcher power supply, power supply flows to the electronic system of lock by trigger switch.The idle running of Single-chip Controlling motor is waited for the tooth 6a of gear meshing.Plectrum and cloudy locker are rotated further under lock gravity and the power effect of bearing circle top.

4. the tooth 6a of gear and power system gear mesh, power is exported by motor, drives main shaft 4 and rotates plectrum and cloudy lockers, and behind the certain hour, driving lever 13 leaves trigger switch 11a, and power supply is fully by Single-chip Controlling.Again after a period of time, cloudy locker clamping direction dish, this moment motor current-limiting circuit working and trigger micro controller system and stop electric machine rotation.Micro controller system withdraws from power supply control, and cuts off whole circuit supply.Be locked into into no current and wait for unlocking condition.

5. lock is triggered by the car owner, wake the success of micro controller system comparison password up after, micro controller system is closed current-limiting circuit and is controlled that motor reversal drives cloudy lockers by main shaft 4 and plectrum rotates, until touch trigger switch 11a, keeps electric machine rotation and stops electric machine rotation after 1 second.This moment, motor power output gear and tooth 6a broke away from, and micro controller system is reported to the police and waited for that the car owner takes away lock from bearing circle.If overtime lock is locked bearing circle automatically again.

When the car owner takes away lock from bearing circle, torque spring drives main shaft 4 and rotates, and its rotational angle is limited by driving lever 13 and steering wheel position, when driving lever 13 breaks away from trigger switch 11a, cuts off the power supply after the micro controller system perception, and enters no current and wait for and close lock status.Until lock complete departure direction dish, lock is considered as opening fully.
