Description

Without stake public bicycles smart lock

Technical field

The lock on public bicycles is the utility model is related to, particularly one kind is without stake public bicycles smart lock.

Background technology

With the development of the society, urban traffic pressure gradually increases, traffic congestion phenomenon is increasingly severe, and people start to carry Green Travel mode is advocated, is taken public transport, and selection cycling trip mode is encouraged.Present many city streets Occur riding public bicycles trip people on road, the appearance of public bicycles both can overcome the disadvantages that the deficiency that public transport changes into, and can Deficiency is docked in the short distance for making up cell to bus station, and the modern personnel for lacking motion can be given to play the effect taken exercises Fruit.

With the appearance of public bicycles, car locking of returning the car becomes problem, it is necessary on the stake position also at appointed place, And easily occur：1 specified point of returning the car is distant, it has not been convenient to；2 specified point stake positions of returning the car are full；On 3 midway working are had no way Lock, worry stolen；4 public bicycles cards are lost or left behind, and can not use.And then occur in some big cities public certainly without stake Driving, the public bicycles with coded lock, these have been used electronics unlocking, unlocked using motor-driven gear substantially, and power consumption is big, Using the easily very fast time to occur for a long time, power consumption is complete to be used.

The content of the invention

For problem above, the utility model is disclosed without stake public bicycles smart lock, including：Nitinol alloy wire, consolidate Fixed end, detection switch, substrate, support, control board and lock core, it is characterised in that：Described nitinol alloy wire both ends pass through Fixing end is fixed on substrate, and described fixing end is on substrate, and on substrate, described substrate is propping up described detection switch On frame, described lock core is under substrate, and under support, affiliated detection switch is connected to described control board by wire In control board, for detecting the open and-shut mode of lock, described nitinol alloy wire both ends are connected to control circuit by wire On plate, described control board receives the signal of net background, adds energization to nitinol alloy wire both ends, thermal deformation pulls lock Core is unlocked.

Principle of the present utility model is：The utility model sends letter of unlocking by net background to the control circuit in lock Number, control circuit powers up to nitinol alloy wire both ends, due to the resistance of nitinol alloy wire in itself plus electric current by producing heat Amount, and the characteristic of nitinol alloy wire in itself：Temperature distortion is shortened, and then pulls lock pillar, drives lock to unlock, and detection switch is broken Open, control circuit is by information transfers such as unlocking condition signal, GPS location signals to net background；When need to return the car car locking when, hand Dynamic to lock lock, now lock pillar returns to original position, promotes detection switch shell fragment, and detection switch, which closes, gives the electric signal of control circuit one, Control circuit is by the information transfer for blocking of returning the car to net background.

The disclosed energization thermal contraction selected without stake public bicycles smart lock, described nitinol alloy wire of the utility model Rate shortens in 5%-7%, both ends power-up after-contraction and lock pillar can be pulled to unlock, recovery after power cut original state.Each control circuit is received After order of unlocking is transmitted to net background, control circuit gives nitinol alloy wire both ends to be powered, and sets the maximum conduction time to be 200ms, to prevent overheat from irrecoverable deformation occurs, cause to damage.

The utility model is disclosed without stake public bicycles smart lock, and described substrate, which is provided with, to be used to prevent Nitinol The limiter of silk dislocation.

The utility model is disclosed to include lock pillar, lock and spring without stake public bicycles smart lock, described lock core.Institute The lock pillar stated includes post core, rubber layer and layer of brass, and on the one hand described layers of copper is used to radiate, can be by nitinol alloy wire after unlocking Caused heat is guided in time, on the one hand plays wear-resisting effect, and post core and layer of brass are kept apart, avoided by described rubber layer Contact conducting, effectively prevents post core from connecing electricity, so as to prevent that lock strap is electric.

The utility model is disclosed without stake public bicycles smart lock, and described substrate is the exotic material system of insulation Into.

The utility model is disclosed to be provided with for positioning without stake public bicycles smart lock, described control board GPS module and the GSM network module for being transferred to net background data.

Compared with prior art, its advantage is the utility model：

1 the utility model is simple in construction, and no motor driving, power consumption substantially reduces, and extends the cruising time of battery.

2 pairs of nitinol alloy wire protections, prevent heating from excessively damaging, the limiting time heating power time.

The control of 3 mobile phone ends, which is borrowed, returns the car, and can check public bicycles situation nearby（Distance, quantity etc.）, return the car and do not receive The limitation of stake position, management are easy to use.

4. being unlocked using to nitinol alloy wire direct-electrifying heating contraction distortion mode, without heat transfer, whole NiTi closes Spun gold is heated evenly unanimously, and the unblock efficiency high time is short.

5. using without stake formula public bicycles, the fixed parking production institute of setting can be reduced, the setting of stake is reduced, is advantageous to city The adjustment of making rational planning for of traffic.
