The specific embodiment

Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment.

The utility model is to utilize key to drive lock body to rotate, and changes electric energy into by mechanical energy and realizes self power generation, and its core institution is lock body.

Lock body: except key, all mechanisms all are arranged on lock body directly or indirectly, especially are used for installing lock core.As shown in Figure 1, lock body comprises a lock body 101, and electric lock core 201 is arranged on lock body 101.Offer a groove 102 in lock body 101 fronts, shifting block 103 wherein is housed, shifting block 103 passes through arrangement of clutch or is connected with electric lock core 201 regularly; Shifting block 103 is controlled dead bolt by the driver part in lock box and is stretched out and retract, and is unblanked and block action.

The electric lock core both had been installed on lock body also during organic lock core, shifting block 103 is connected with machine lock core 301 with electric lock core 201 by symmetrical arrangement of clutch.As shown in Figure 2, it comprises that two Φ are just as axle iron block 202,302, all can be arranged in the Φ shape centre bore 104 of shifting block 103.Φ is greater than the length of Φ shape centre bore 104 just as the length of axle iron block 202,302.Also have respectively Φ shape centre bore at the front end of electric lock core 201 and the front end of machine lock core 301, cylindricality jacking block 203,303 is housed in hole separately, Φ is contained in the Φ shape centre bore of lock core just as the part of axle iron block 202,302, and is withstood by the cylindricality jacking block.When key inserts from the electric lock core, key cylindricality jacking block 203 and Φ just as axle iron block 202 together toward extrapolation, make Φ enter 104 li of Φ shape centre bores just as axle iron block 202 parts, Φ is ejected Φ shape centre bore 104 just as axle iron block 302 simultaneously, and key drives the electric lock core and shifting block rotates.When key slave lock core inserts, key cylindricality jacking block 303 and Φ just as axle iron block 302 together toward extrapolation, make Φ enter 104 li of Φ shape centre bores just as axle iron block 302 parts, and Φ is ejected Φ shape centre bore 104 just as axle iron block 202, key band motivation lock core and shifting block rotate.

When electric lock core or machine lock core only are installed on lock body, shifting block can directly be fixedly linked with electric lock core or machine lock core.Front at lock body 101, as shown in Figure 1,3, also offer a groove 105, driving wheel 204 is housed in groove 105, driving wheel 204 fixed covers are located on the front end external diameter of electric lock core, driving wheel 204 driven pulley 205 that is connected with a joggle, driven pulley 205 is arranged in the input rotating shaft of gearbox, and the gearbox output revolving shaft is connected with the microgenerator rotating shaft and (gearbox is not shown in figure, because this embodiment is that gearbox is integrated in the rotating shaft of microgenerator 206), microgenerator 206 is connected with consuming parts such as control circuit boards, to it, provides power supply.Microgenerator 206 can be arranged on lock body 101, also can together with lock body, be arranged on lock box.

Above-mentioned driving wheel 204 is a kind of gear transmission mode with driven pulley 205 engaged transmission modes, its effect is exactly for the power transmission, the mode that simultaneously should understand this power transmission can also have multiple, such as driving wheel 204 with driven pulley 205 by the transmission of belt, driving wheel 204 and driven pulley 205 are by the transmission of tooth bar, driving wheel 204 and driven pulley 205 pass through the transmission of chain etc., more than can be referred to as a kind of transmission mechanism.Simultaneously, gear also can have roller gear or bevel gear.

Microgenerator 206 produces electric process: insert lock core with key, along with the rotation of key band movable lock core, driven wheel engagement carry-over moment, no matter forward is still reversed, can have electric energy to produce.Because microgenerator 206 is rotate and change electric energy into by mechanical energy by the engagement of driven wheel, so as long as insert in lock core and rotate with key, just have electricity and produce, be i.e. so-called instant generating.Microgenerator includes gearbox, and the rotor of microgenerator rotates with the rotation of driven pulley, has higher rotating speed.

The utility model drives the high-speed micro generator by the moment of key turns, this point is the flywheel self-powering apparatus that is different from patent CN200520061019.3, difference is 1, patent CN200520061019.3 sets up to put a man-operated mechanism (such as stay cord; rocking handle) and drive generator; its operating process is first manually generating; then input password, do electronic recognition, then by the electric energy drive motors, make the dead bolt action; The utility model is to produce electric energy by the moment of key turns, completes the driving with arrestment mechanism that sets of password in the process of key turns, finally remains by the moment of key turns dead bolt is moved.For the user, the whole process of unblanking is accomplished without any letup, and with the process of unblanking of standard machinery lock, there is no obvious difference.2, generally, the user can not first manually generate electricity at every turn before the input password, so patent CN200520061019.3 does not just generate electricity with it when battery has electricity just as the backup of battery; And the utility model generating and the everything such as set and combine together is not to design as backup.3, the power facility more complicated of patent CN200520061019.3, this drives dead bolt relevant with it with motor, because usually the motor driven latch tongue needs the lasting electric energy of 5 volts 150 milliamperes, so large electric energy provides very and requires great effort by the moment of key turns; And the electric energy peak value that the utility model is used is 5 volts 30 milliamperes, so can produce by the moment of key turns required electric energy.

Electrification structure in the utility model also mode of available " generator+rechargeable battery " substitutes, as shown in Figure 5, the electric energy of microgenerator 206 outputs is after the rectification energy storage, deposit rechargeable battery in, rechargeable battery obtains stable power supply through dcdc converter, as the power supply of control circuit or testing circuit etc., also be used for drive magnet and radiating circuit etc. simultaneously.This mode has more advantage: voltage is more stable, when electric quantity of rechargeable battery is inadequate, still can lean on generator work, and battery is charged.

The utility model can be used for pure electronic lock, also can be used for magnetic electron lock, Photoelectric lock, optical fiber lock etc.
