The parking places comprise default parking places allowed by the remote management system and new parking places which are comprehensively arranged and set by the remote management system after calculation according to parking position application provided by a user and by combining with real geographic positions and big data; and if the remote management system does not agree with setting a new parking place, the car returning indicator lamp is allowed to be not on, the voice prompt is not allowed to return the car, and the remote management system feeds back the information of the closer parking place where the car returning is allowed around the mobile phone end of the user or the voice prompt.

The temporary parking method comprises the following steps: when the user of the bicycle C does not put forward a returning application and locks the lock column 4 of the bicycle C into the lock hole 11 of the first locking unit 6 of the bicycle C, the locking sensing block 12 of the first locking unit 6 receives the locking sensing and then judges that the bicycle C is temporarily stopped, and the returning success indicating lamp of the indicating lamp module is not on, so that the user can conveniently judge that the bicycle is temporarily stopped and the system continues to time or charge the bicycle;

when the user finishes the temporary parking, the two-dimensional code on the bicycle C is scanned through the mobile phone, the communication module sends a vehicle using request signal to the remote management system, the remote management system judges that no bicycle matched with the remote management system in radio frequency exists, an unlocking signal is fed back to the used bicycle C, the motor 8 of the first locking unit 6 runs to drive the eccentric wheel 15 to run, the locking block 10 is ejected, the locking column 4 pops out under the action of the bicycle compression spring 13 at the moment to complete the unlocking action, and the user can continue to ride.

The temporary parking method further comprises a mistaken locking state, when the bicycle C is temporarily parked, when the bicycle D is locked into the bicycle C in series, the bicycle D is judged to be invalid, and when the bicycle D is in the mistaken locking state, the control system does not stop timing or charging of the bicycle D, and meanwhile, the motor 8 of the second locking unit 7 of the bicycle C rotates to complete unlocking, the lock column 4 of the bicycle D is popped out, and locking action is failed.

Specifically, the bicycle lock of the present embodiment includes the following:

1. when a user stops temporarily in the riding process, and does not have the intention of returning the vehicle, the lock column 4 can be inserted into the lock hole 11 of the first locking unit 6, at the moment, the conical surface at the top of the lock column 4 pushes the locking block 10 to lift up, the lock column 4 can continue to go deep into the annular gap, the locking block 10 resets under the action of the reset spring 14 to block the annular gap of the lock column 4, the locking induction block 12 receives induction to complete the locking action, and at the moment, the returning success indicator lamp is not bright.

2. When a user needs to return the bicycle, the lock column 4 can be inserted into the lock hole 11 of the second locking unit 7 of another bicycle shown in fig. 6, the locking block 10 is clamped in the annular notch of the lock column 4, the upper locking sensing block 12 receives sensing to complete the locking action, and the returning success indicator light is on at the moment to allow the next bicycle to continue to be parked in series.

3. To returning the car as the bow part bicycle of fig. 6, if the bicycle falls into the system and defines the permission scope of returning the car in advance, the user passes through the removal end such as cell-phone APP and applies for the system, system feedback signal is for permitting the pilot lamp of returning the car to light, it parks as the bow part bicycle to allow, the user can penetrate lock post 4 in the lockhole 11 of first locking unit 6, the response piece 12 of locking accepts the response, the action of returning the car of accomplishing locking, the pilot lamp of allowing to return the car this moment goes out, the successful pilot lamp of returning the car lights, allow next bicycle to continue to park in series and return the car.

4. For the returning of the bicycles as shown in the head part of fig. 6, if the bicycles do not fall into the range of the system for previously defining the allowable returning, the user can visually observe the periphery without the parking points of the same type of bicycles, when a user applies for a remote management system through a mobile terminal such as a mobile phone APP, if the remote management system does not allow parking of a bicycle as a head part and allows a returning indicator light to be turned off, the remote management system makes position judgment according to a bicycle GPS module, according to the calculation of the parking radius defined in advance, the nearest car returning point is prompted in an APP or voice mode, if the system can be defined in a densely populated area, the car returning point exists in the range of 100 meters in radius, in the population evacuation area, a returning point exists in the range of 500 meters in radius, the returning direction is prompted, a user can go to the returning by himself, and the lock columns 4 are connected in series and locked in the lock holes 11 of the second locking units 7 of the previous bicycle after the returning is finished.
