Matched with the local authentication information which receives, after the match is successful, unlocking CPU sends a command to logic
Control module, makes Logic control module power electromagnetic induction coil 22.After electromagnetic induction coil 22 is powered
Magnetic field is produced, magnetic field force drives the electromagnetic bolt 23 in reel 21 to release forward, simultaneously because reel 21
The spring on electromagnetic bolt 23 is blocked, with the advance of electromagnetic bolt 23, spring gradually reduces.23 band of electromagnetic bolt
Dynamic jointer 24 is entered in the keyhole of cam 25.Unlocking CPU sends the life that the match is successful to CPU is started
Order, after startup CPU is connected to order, drives display lamp 12 to show green light.User rotates key 2, completes out
Lock.If overtime, beyond coil being projected into due to a part for electromagnetic bolt 23, cause electromagnetic induction coil 22
The magnetic field force for producing magnetic field is reduced to the driving force of electromagnetic bolt 23, elastic force of the magnetic field force less than spring, electricity
Magnetic bolt 23 is retreated due to the effect of spring restoring force, while driving jointer 24 to take off from the keyhole of cam 25
Go out, cam 25 is rotated under self gravitation effect,.When electromagnetic bolt 23 is again completely in reel 21,
Even if the magnetic field force that electromagnetic induction coil 22 produces magnetic field drives electromagnetic bolt 23 to release again.Due to jointer
24 improper with the keyhole entry angle of cam 25 cause jointer 24 from being re-introduced into the key of cam 25
In hole, failure of opening the door.And work as after user extracts key 2, due to 22 dead electricity of electromagnetic induction coil, to electromagnetism
Bolt 23 produces the magnetic field of repulsion and disappears, and electromagnetic bolt 23 is returned in reel 21.Jointer 24 and cam 25
Keyhole depart from, open the door failure.
More than, the only specific embodiment of the present invention, but protection scope of the present invention is not limited thereto,
Any those familiar with the art the invention discloses technical scope in, change can be readily occurred in
Or replace, should all be included within the scope of the present invention.Therefore, protection scope of the present invention Ying Yiquan
The protection domain that profit is required is defined.
