The unlock pulling plate 203 is fitted at the unlock opening 113 from outside of the shell and connected to an internal pull plate 204, which buckles the first pull rod 201 and second pull rod 202. The return spring component comprises the first return spring 205 connected with the first pull rod 201 and the second return spring 206 connected with the second pull rod 202.

A locking component is arranged in the shell, which comprises a motor component, a rotating stop block 301 with two swing arms 311 and 312 and a driving spring 308, wherein the motor component comprises a motor 302, a turbine 303 provided in the motor rotating shaft and a pushing component driven by the turbine 303. The pushing component comprises a driving elastic component 304 provided with a ring 341 and a double-arm 342 connected with the ring 341, a guide rod 305, a hollow “H” shaped guide wheel 306 and a push plate 307. The guide wheel 306 comprises a guide ring 361 and a hollow inverted T shaped guide tube 362 coupled with the guide ring 361. The driving elastic component 304 could be formed by folding a circle at the middle of a spring. The guide rod 305 and pushing plate 307 are respectively fitted on each side of the turbine 303, wherein the guide wheel 306 is fitted through the guide rod 305, the ring 341 of driving elastic component 304 is fitted over the guide wheel 306, the double arm 342 of the driving elastic component 304 is placed to hold the turbine 303 and fitted on the pushing plate 307. The motor component and driving spring 308 coordinately drive the rotating stop block 301 to lockup or release the pull rod 201 and second pull rod 202.

An electromagnetic induction (/Rifidi) component is fitted in the shell, which comprises a battery 401 used for providing working power supply, a control circuit board 402, an induction (/Rifidi) coil 403 connected with the control circuit board 402, an indicating light 404 with two indication state (displaying red and green).

The principle of operation of the present invention is:

As shown in FIG. 3, lockup state: The push plate 307 releases the swing arm 311 of the rotating stop block 301, thus the driving spring 308 is in initial condition, the swing arm 312 of the rotating stop block 301 is set against the first pull rod 201 and second pull rod 202, both of which are locked and cannot move.

Unlock process: When the magnetic card is placed on the shell of the present invention (close to the induction (/Rifidi) coil 403), the electromagnetic induction (/Rifidi) component induces the signal, which then controls the indicating light 404 to display green, drives the motor 302 to rotate and drives the turbine 303 to make clockwise rotation (the turbine 303 could be also designed to make counterclockwise rotation in unlock process). The turbine 303 rotates and drives the driving elastic component 304, which moves forward by the aid of guide wheel 306 and the guide lever 305. Driven by the driving elastic component 304, the push plate 307 moves forward and pushes against the swing arm 311 of the rotating stop block 301, which rotates and simultaneously strain the driving spring 308, thus the swing arm 312 of the rotating stop block 301 leaves the first pull rod 201 and the second pull rod 202. The present invention is in unlock state at the moment, users can pull the unlock pulling plate 203, which moves and drives the first pull rod 201 and the second pull rod 202 to move by internal pull plate 204, thus the first buckle 211 and the second buckle 221 release the locked parts, simultaneously the first return spring 205 and the second return spring 206 are compressed.

As shown in FIG. 4, unlock state: The push plate 307 pushes against the swing arm 311 of the rotating stop block 301, the driving spring 308 is in strained condition, the swing arm 312 of the rotating stop block 301 leaves the first pull rod 201 and the second pull rod 202. Users can pull the unlock pulling plate 203 to drive the first pull rod 201 and the second pull rod 202.

Locking process: In the condition that the unlock pulling plate 203 is not pulled, the first return spring 205 and the second return spring 206 are in initial condition, both of which push the first buckle 211 and the second buckle 221 to the lockup opening 112, 112′. Under this condition, when users place the magnetic card on the shell of the present invention (close to the induction (/Rifidi) coil 403), the electromagnetic induction (/Rifidi) component induces the signal, which then controls the indicating light 404 to display red, drives the motor 302 to rotate and drives the turbine 303 to make counterclockwise rotation (opposite to the rotation in unlock process). The turbine 303 rotates and drives the driving elastic component 304, which moves backward by the aid of guide wheel 306 and the guide lever 305. Driven by the driving elastic component 304, the push plate 307 moves backward and releases the swing arm 311 of the rotating stop block 301, simultaneously the driving spring 308 restores to its initial state, the rotating stop block 301 then rotates, thus the swing arm 312 of the rotating stop block 301 is set against the first pull rod 201 and the second pull rod 202. The present invention is in lockup state at the moment, the first pull rod 201 and the second pull rod 202 are locked and can not move.

In the present invention, once the induction (/Rifidi) coil 403 induces the magnetic card and drives the motor 302 to make anticlockwise rotation, then next time the induction (/Rifidi) coil 403 will induce the magnetic card and drive the motor 302 to make clockwise rotation. This means the turbine 303 makes counterclockwise and clockwise rotation in turns, correspondingly the push plate 307 moves backward and forward in turns.

Lock up process: Firstly the compatible magnetic card is placed close to the induction (/Rifidi) coil 803 so that the electromagnetic induction (/Rifidi) component receives a signal and controls the motor 603 to rotate, which ensures that the push block 606 releases the swing arm 611 of the rotating stop block 601 (push button 705 is then be able to be pressed), thus the swing arm. 612 of the rotating stop block 601 rotates downward at the function of the driving spring 602, that means the unlock state is verified before lockup. The push button 705 is then pressed to drive the torque part 701, thus the linkage plate 703 is pushed to make the trip 731 not hitch the side lock cover 721, which is then open. After that, the parts to be locked are inserted from the lockup opening 514 and placed at the side lock latch hook 723, then the side lock cover 721 is pushed down and pulls the side lock latch hook 723 to hitch the parts to be locked. The compatible magnetic card is then placed close to the induction (/Rifidi) coil 803 so that the electromagnetic induction (/Rifidi) component receives a signal and controls the motor 603 to rotate, which drives the push block 606 to press the swing arm 611 of the rotating stop block 601 down, accordingly the swing arm 612 of the rotating stop block 601 rotates upward and sets against the linkage plate 703 of the two buckle lock sets 700 and 700′, thus the linkage plate 703 is locked and cannot move. The linkage plate 703 sets against the torque part 701, thus the push button 705 cannot be pressed, and lockup is completed.

Unlock process: The compatible magnetic card is placed close to the induction (/Rifidi) coil 803 so that the electromagnetic induction (/Rifidi) component receives a signal and controls the motor 603 to rotate, which drives the push block 606 to release the swing arm 611 of the rotating stop block 601, accordingly the swing arm 612 of the rotating stop block 601 rotates downward at the function of the driving spring 602 and leaves the linkage plate 703 of the two buckle lock sets 700 and 700′, thus the linkage plate 703 is not locked and the purpose of unlock is achieved.

As shown in FIG. 17, in order to avoid the inconvenience of being unable to unlock when the battery runs out of power, the control circuit board is provided with a low voltage detect circuit, which comprises a detection module used for detecting the voltage of the battery 801 and a control module used for controlling the locking component 600 to release the buckle lock sets 700 and 700′ when the voltage of the battery 801 is under the pre-set value. In particular, when the voltage of the battery 801 is under the pre-set value, the control module controls the motor 603 to rotate, which drives the push block 606 to release the swing arm 611 of the rotating stop block 601. Accordingly, the swing arm 612 of the rotating stop block 601 rotates downward at the function of the driving spring 602, and leaves the linkage plate 703 of the two buckle lock sets 700 and 700′, thus the linkage plate 703 is not locked and the purpose of unlock is achieved.
