Technical Field

[0001] The present invention relates to the field of public transportation, and in particular to a shared or public bicycle lock and a management method thereof. Background Art

[0002] The emergence of shared bicycles in recent years has brought great convenience to people, but the development of shared bicycles from prosperity to decline has exposed many problems. For example, as the number of shared bicycles increases, the bicycles are parked in disorder and inconvenient to manage. This not only increases the operating costs of shared bicycles, but also causes some social problems such as obstruction of traffic and untidy city streets, further increasing the management costs of cities. For urban public bicycles, for the sake of convenience of management, they are placed at fixed points, which are often not very convenient to pick up and use due to the location and number of setting points. Summary of the invention

[0003] The purpose of the present invention is to solve the above-mentioned problems in the prior art and to provide a shared or public bicycle lock and management method, which can effectively solve the problem of disorderly parking of shared bicycles, reduce the operating costs of shared bicycles, and reduce social problems.

[0004] In order to achieve the above object, the present invention adopts the following technical scheme:

[0005] A shared or public bicycle lock comprises a lock body device, wherein the lock body device comprises a lock body, a lock column, a first locking unit, and a second locking unit. The lock column is connected to the lock body by a chain, and a bicycle A and a bicycle B are defined. The first locking unit of bicycle A cooperates with the lock column of bicycle A to lock bicycle A, and the second locking unit of bicycle A cooperates with the lock column of bicycle B to lock bicycle B and bicycle A in series.

[0006] The first locking unit and the second locking unit both include a motor, a locking block, a return spring, a compression spring, an eccentric wheel, and a lock hole; the compression spring is installed in the lock hole; the eccentric wheel is connected to the rotating shaft of the motor; one end of the locking block is a horizontally arranged connecting part, and the other end of the locking block is a locking part arranged in an inclined plane, the connecting part is located at the top of the eccentric wheel, and the locking part faces the lock hole; the return spring is located at the top of the connecting part; one end of the lock column plugged into the lock hole is provided with an annular notch adapted to the locking part; wherein, when the lock column is plugged into the lock hole, the lock column acts on the locking part to make the locking block move in a direction deviating from the lock hole and compress the return spring, the lock column continues to move against the compression spring, and under the action of the return spring, the locking block moves in the direction of the lock hole so that the locking part is clamped in the annular notch of the lock column, thereby locking the bicycle; when the motor rotates and drives the eccentric wheel to rotate, the locking block moves in a direction deviating from the lock hole, and under the action of the compression spring, the lock column is ejected from the lock hole, thereby unlocking the bicycle.

[0007] The lock body is provided with a lock post through hole, and the upper end of the lock post is provided with a limiting edge extending outward, and the size of the limiting edge is larger than the size of the lock post through hole, so that the lock post is fixed in the lock post through hole.

[0008] The present invention also includes a control unit arranged in the lock body device; an RFID radio frequency tag is arranged on the lock column, and the first locking unit and the second locking unit both include a locking sensor block and a limit sensor, the locking sensor block is located above the lock hole, and the limit sensor is located on one side of the eccentric wheel; the control unit includes an MCU control module and a communication module, a GPS module, an RFID radio frequency module, a power module, a voice module and an indicator light module connected to the MCU control module; the motor, the locking sensor block and the limit sensor are all connected to the MCU control module, the locking sensor block is used to transmit unlocking and locking information to the MCU control module, and the limit sensor is used to sense the rotation of the motor And transmit the information to the MCU control module; the communication module is used to realize the communication and data interaction between the remote management system and the MCU control module; the GPS module is used to locate the bicycle; the power module is used to provide power to the control unit; the RFID radio frequency module is used to identify whether the parked bicycle has been locked in series; the indicator light module is used to display the status of the bicycle, including an indicator light for allowing the return of the bicycle and an indicator light for successful return of the bicycle; the voice module is used to give voice reminders to the user; the MCU control module is used to interact with the remote management system, receive signals from the locking sensor block and the limit sensor, and control the operation of the motor and each module.

[0009] A method for managing shared or public bicycles, including a method for returning bicycles, wherein each bicycle is numbered according to information contained in an RFID radio frequency tag provided on its bicycle lock column, and for the first bicycle to be returned, a user needs to submit an application through a mobile phone; bicycle A is defined as the first bicycle, the user of bicycle A submits an application for returning the bicycle, and arrives at the parking location, the bicycle lock voice prompts that the bicycle is allowed to be returned, and at the same time, an indicator light of the indicator module that allows the bicycle to be returned is on, and when the user locks the lock column of bicycle A into the lock hole of the first locking unit of bicycle A, the locking sensor block receives the locking induction and determines that the bicycle is successfully returned, stops the timing or billing of the bicycle, and a voice prompt indicates that the bicycle is successfully returned, and at the same time, the indicator light of the indicator module that allows the bicycle to be returned is off, and the bicycle is returned. The return success indicator light is on, and bicycle A is the first bicycle. The remote management system marks the number information of the first bicycle and allows the next bicycle, bicycle B, to be locked in series for return. When the bicycle B user locks the lock column of bicycle B into the lock hole of the second locking unit of bicycle A, the locking sensor block of the second locking unit receives the induction, and the RFID radio frequency tag on the lock column of bicycle B and the RFID radio frequency module of bicycle A complete the reading of the corresponding bicycle number information. The remote management system therefore establishes a pairing relationship between the front and rear connected bicycles, determines that the bicycle is returned successfully, stops the timing or billing of the bicycle use, and the return success indicator light of the indicator module of bicycle B is on, and a voice prompt is given that the bicycle is returned successfully, allowing the next bicycle to be connected in series again, and so on.

[0010] The parking locations include default parking locations allowed by the remote management system and new parking locations that are established based on the parking location application submitted by the user in combination with the actual geographical location and calculated through big data; when the remote management system does not agree to establish a new parking location after the user submits an application to return the vehicle, the indicator light for allowing vehicle return will not light up and a voice prompt will be given indicating that vehicle return is not allowed, and the remote management system will feedback information about nearby parking locations that allow vehicle return to the user on the mobile phone or through a voice prompt.

[0011] A method for managing shared or public bicycles also includes a temporary parking method. When a user of bicycle C does not apply for returning the bicycle, the locking column of bicycle C is locked into the locking hole of the first locking unit of bicycle C. After receiving the locking induction, the locking sensing block of the first locking unit determines that bicycle C is temporarily parked, and the return success indicator light of the indicator light module is off, so that the user can judge that the bicycle is temporarily parked, and the system continues to count or charge for the use of the bicycle.

[0012] The temporary parking method also includes a mis-locking state. When bicycle C is temporarily parked, when bicycle D is locked in series with bicycle C, it is determined that the return of bicycle D is invalid and is in a mis-locking state. The control system does not stop the timing or charging of bicycle D. At the same time, the motor of the second locking unit of bicycle C rotates to complete the unlocking action, and the lock column of bicycle D pops out, causing the locking action to fail.

[0013] A method for managing shared or public bicycles, further comprising a method for picking up a bicycle, wherein the method for picking up a bicycle is as follows: a user needs to pick up the bicycles in order from the back to the front by scanning characteristic information on the bicycles according to the order in which they are locked; for the rear bicycle, when the characteristic information is scanned, the remote management system controls the motor of the second locking unit of the lock of the preceding bicycle paired with it to rotate to complete the unlocking action according to the established pairing relationship between the preceding and following bicycles; for the leading bicycle and temporary parking, when the characteristic information is scanned, the remote management system controls the motor of the first locking unit of the lock of the leading bicycle and the temporary parking to rotate to complete the unlocking action according to the situation that there is no paired vehicle; for the leading bicycle For a bicycle that is not the first or the last bicycle, when the characteristic information is scanned, the remote management system determines that there is a paired bicycle behind it, and the remote management system does not issue an unlocking instruction; for a bicycle that is not the first or the last bicycle, when the characteristic information is scanned, the remote management system determines that there are paired bicycles in front and behind it, that is, when there are two paired bicycles at the same time, the remote management system does not issue an unlocking instruction, so as to ensure that users take the bicycles from the back to the front in sequence; the unlocking action includes when the eccentric wheel rotates one circle, the limit sensor receives the induction, the MCU control module controls the motor to stop rotating, and when the lock column is separated from the locking sensor block, the locking sensor block receives the separation induction, and the system starts timing or billing the use of the bicycle.

[0014] When the first bicycle is set up in a fixed parking lot and is not allowed to be used, the remote management system marks the vehicle number information so that the user cannot unlock it by scanning, and the indicator light module's return permission indicator light and return success indicator light are on at the same time, making it easier for the user to determine that the bicycle is a fixed parking lot.

[0015] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0016] 1. The present invention is based on the improvement of the bicycle lock hardware, so that the bicycle itself can be used as a movable parking pile to park the next bicycle in series. Combined with the management and control of the system, it can effectively solve the problems of disorderly parking of shared bicycles and the inconvenience of fixed-point placement and placement of public bicycles.

[0017] 2. When using, users need to scan the characteristic information on the bicycles in the order of locking them in, and use them from the back to the front. When the user returns the bicycle after use, except for the first bicycle, the subsequent bicycles need to be locked in series with the first bicycle through the designed bicycle lock chain structure to end the use status, and the system will end the bicycle usage time or billing. The system also allows users to temporarily park bicycles without returning them.

[0018] 3. The first bicycle can be used as a fixed parking post or a movable and rideable parking post. The system can combine the user's parking needs and big data calculations, and flexibly define the parking location after the user's application and the system feedback of the parking permission signal. It can increase the placement points in a uniform manner in densely populated areas and avoid important traffic arteries to avoid the disorderly parking of shared bicycles. At the same time, parking is flexible, which improves the shortcomings of public bicycle parking posts, such as the small number of fixed locations, large construction investment and long cycle, resulting in inconvenience in use. It is convenient for bicycle management and users to return the bicycles. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] like Figures 1 to 3 and Figure 6 As shown, a shared or public bicycle lock described in this embodiment includes a lock body device and a control unit 2 disposed in the lock body device;

[0028] The lock device comprises a lock body 1, a lock column 4, a first locking unit 6, and a second locking unit 7. The lock column 4 is connected to the lock body 1 through a chain 3. A bicycle A and a bicycle B are defined. The first locking unit 6 of bicycle A cooperates with the lock column 4 of bicycle A to lock bicycle A. The second locking unit 7 of bicycle A cooperates with the lock column 4 of bicycle B to lock bicycle B and bicycle A in series.

[0029] Specifically, the first locking unit 6 and the second locking unit 7 each include a motor 8, a locking block 10, a return spring 14, a compression spring 13, an eccentric wheel 15, and a locking hole 11; the motor 8 is a low-speed motor;

[0030] The compression spring 13 is installed in the lock hole 11; the eccentric wheel 15 is connected to the rotating shaft of the motor 8; one end of the locking block 10 is a horizontally arranged connecting portion, and the other end of the locking block 10 is a locking portion arranged at an inclined surface, the connecting portion is located at the top of the eccentric wheel 15, and the locking portion faces the lock hole 11; the reset spring 14 is located at the top of the connecting portion; one end of the lock column 4 inserted into the lock hole 11 is provided with an annular notch adapted to the locking portion.

[0031] like Figures 1-2 As shown, in this embodiment, the lock body 1 is provided with a lock post through hole 16, and the upper end of the lock post 4 is provided with a limiting edge extending outward, and the size of the limiting edge is larger than the size of the lock post through hole 16, so that the lock post 4 is fixed in the lock post through hole 16. During the riding process, the user can put the lock post 4 into the lock post through hole 16.

[0032] like Figure 4 As shown, the bicycle lock can be installed on the rear part of the bicycle frame, near the rear tire.

[0033] like Figures 2-3 As shown, the front end of the lock column 4 is provided with an RFID tag 5, the first locking unit 6 and the second locking unit 7 both include a locking sensor block 12 and a limit sensor 9, the locking sensor block 12 is located above the lock hole 11, and the limit sensor 9 is located on one side of the eccentric wheel 15; wherein the limit sensor 9 and the locking sensor block 12 are magnetic induction elements.

[0034] like Figure 1 and Figure 5 As shown, the control unit 2 is installed in the lock body 1, including an MCU control module and a communication module, a GPS module, an RFID radio frequency module, a power module, a voice module and an indicator light module connected to the MCU control module;

[0035] The motor 8, the locking sensor block 12 and the limit sensor 9 are all connected to the MCU control module. The locking sensor block 12 is used to transmit the unlocking and locking information to the MCU control module, and the limit sensor 9 is used to sense the rotation of the motor 8 and transmit the information to the MCU control module.

[0036] The communication module is used to realize communication and data exchange between the remote management system and the MCU control module; the GPS module is used to locate the bicycle; the power module is used to provide power to the control unit 2; the RFID radio frequency module is used to identify whether the parked bicycle has been locked in series; the indicator light module is used to display the status of the bicycle, including an indicator light for allowing the return of the bicycle and an indicator light for successful return of the bicycle; the voice module is used to give voice reminders to the user, and to prompt whether the return of the bicycle is successful or to prompt the nearest return point through voice; the MCU control module is used to exchange information with the remote management system, execute control instructions issued by the remote management system, receive signals from the locking sensor block 12 and the limit sensor 9, and control the operation of the motor 8 and each module.

[0037] In this embodiment, the actions of locking the bicycle include:

[0038] When the lock column 4 is inserted into the lock hole 11, the front end of the lock column 4 acts on the locking part of the locking block 10, causing the locking block 10 to move in a direction away from the lock hole 11 and compress the reset spring 14. The lock column 4 continues to move to press against the compression spring 13. Under the action of the reset spring 14, the lock block 10 moves in the direction of the lock hole 11 so that the locking part of the lock block 10 is clamped in the annular notch of the lock column 4, thereby locking the bicycle. At the same time, the locking sensor block 12 receives the induction and feeds back the locking information to the MCU control module.

[0039] In this embodiment, the bicycle unlocking action includes:

[0040] The MCU control module controls the rotation of the motor 8. When the motor 8 rotates and drives the eccentric wheel 15 to rotate, the eccentric wheel 15 can lift the locking block 10, causing the locking block 10 to move in the direction away from the lock hole 11. At this time, the lock column 4 pops out of the lock hole 11 and disengages from the locking sensor block 12 under the action of the compression spring 13. The locking sensor block 12 receives the disengagement induction, and the system starts timing or billing for the use of the vehicle; at the same time, after the motor 8 rotates one circle, when the eccentric wheel 15 rotates one circle, the limit sensor 9 receives the induction, and the MCU control module controls the motor 8 to stop rotating. The locking block 10 is reset under the action of the reset spring 14, waiting for the next locking of the lock column 4.

[0041] The shared or public bicycle management method described in this embodiment includes a bicycle return method, a bicycle temporary parking method and a bicycle pick-up method.

[0042] When bicycles are put into use in batches for the first time, bicycle operators can park the first bicycles according to the population density and even distribution principle and in combination with user application requirements. The first bicycle number will be marked in the system. Figure 6 Tandem locking provides batches of bicycles for users to use.

[0043] The method of retrieving the bicycle is as follows: the user needs to retrieve the bicycle from the back to the front in the order in which the bicycle is locked;

[0044] For the rear bike, when scanning the characteristic information, the user scans the QR code on the bike to be used through the mobile phone, such as scanning Figure 6 The communication module sends a request signal to the remote management system to use the bike. The remote management system uses the established pairing relationship between bike 3 and bike 2 provided by the RFID radio frequency module to control the motor of the second locking unit of bike 2 to rotate and unlock the bike.

[0045] For the first car and temporary parking, when scanning the characteristic information, the remote management system controls the motor of the first locking unit of the first car and temporary parking lock to rotate and complete the unlocking action according to the situation of no paired vehicle;

[0046] For the first bicycle, when scanning the characteristic information, the remote management system determines that there is a bicycle paired with it, and the remote management system does not issue an unlocking instruction;

[0047] For non-first and non-last bicycles, when scanning the characteristic information, the remote management system determines that there are paired bicycles in front and behind, that is, when there are two paired bicycles at the same time, the remote management system does not issue an unlocking instruction, so as to ensure that users pick up the bicycles from the back to the front in turn.

[0048] When the first bicycle needs to be fixed in a fixed parking lot and is not allowed to be taken, the remote management system marks the vehicle number information so that the user cannot unlock it by scanning, and the indicator light module's return permission indicator light and return success indicator light are on at the same time, making it easier for users to determine that the bicycle is a fixed parking lot.

[0049] The return method is as follows:

[0050] Each bicycle is numbered according to the information contained in the RFID tag 5 provided on its bicycle lock column 4. For the first bicycle to be returned, the user needs to apply through the mobile phone; bicycle A is defined as the first bicycle, the bicycle A user applies to return the bicycle, and arrives at the parking location, the bicycle lock voice prompts that the bicycle is allowed to be returned, and at the same time, the indicator light of the indicator module that allows the bicycle to be returned is on, and when the user locks the lock column 4 of bicycle A into the lock hole 11 of the first locking unit 6 of bicycle A, the locking sensor block 12 receives the locking induction and determines that the bicycle is successfully returned, and the timing or billing of the bicycle is stopped. A voice prompt indicates that the bicycle is successfully returned, and at the same time, the indicator light of the indicator module that allows the bicycle to be returned is off, and the indicator light of the successful return is on, and this bicycle A is used as the first The remote management system marks the serial number information of the first bicycle and allows the next bicycle B to be locked in series for return. When the bicycle user locks the lock column 4 of bicycle B into the lock hole 11 of the second locking unit 7 of bicycle A, the locking sensor block 12 of the second locking unit 7 receives the induction, and the RFID radio frequency tag 5 on the lock column 4 of bicycle B and the RFID radio frequency module of bicycle A complete the reading of the corresponding bicycle serial number information. The remote management system therefore establishes a pairing relationship between the front and rear connected bicycles, determines that the bicycle is returned successfully, stops the timing or billing of the bicycle use, and the successful return indicator of the indicator module of bicycle B lights up, and a voice prompt prompts that the bicycle is returned successfully, allowing the next bicycle to be connected in series again, and so on.

[0051] The parking locations include default parking locations allowed by the remote management system and new parking locations that are established based on the parking location application submitted by the user and the actual geographical location and calculated based on big data; if the remote management system does not agree to establish a new parking location, the indicator light for allowing the return of the vehicle will not light up and a voice prompt will be given indicating that the return of the vehicle is not allowed. The remote management system will feedback information about nearby parking locations that allow the return of the vehicle to the user's mobile phone or through a voice prompt.

[0052] The temporary parking method is as follows: when the bicycle C user does not apply for returning the bicycle, the locking column 4 of the bicycle C is locked into the locking hole 11 of the first locking unit 6 of the bicycle C, after the locking sensing block 12 of the first locking unit 6 receives the locking sensing, it is determined that the bicycle C is temporarily parked, and the return success indicator of the indicator module is off, so that the user can determine that the bicycle is temporarily parked, and the system continues to count or charge the bicycle;

[0053] When the user finishes temporary parking, he scans the QR code on the bicycle C with his mobile phone. At this time, the communication module sends a vehicle use request signal to the remote management system. The remote management system determines that there is no bicycle paired with it by radio frequency, and then feeds back an unlocking signal to the bicycle C in use. The motor 8 of the first locking unit 6 runs, driving the eccentric wheel 15 to run, and pushes open the locking block 10. At this time, the lock column 4 pops out under the action of the bicycle compression spring 13, completing the unlocking action, and the user can continue riding.

[0054] The temporary parking method also includes a mis-locking state. When bicycle C is temporarily parked, when bicycle D is locked in series with bicycle C, it is determined that the return of bicycle D is invalid and is in a mis-locking state. The control system does not stop the timing or charging of bicycle D. At the same time, the motor 8 of the second locking unit 7 of bicycle C rotates to complete the unlocking action, and the lock column 4 of bicycle D is ejected, so that the locking action fails.

[0055] Specifically, the bicycle lock returning and locking in this embodiment includes the following steps:

[0056] 1. When the user temporarily stops the bike during riding and has no intention to return the bike, the lock column 4 can be inserted into the lock hole 11 of the first locking unit 6. At this time, the conical surface on the top of the lock column 4 pushes the locking block 10 to lift up, and the lock column 4 can continue to penetrate into the annular gap. The locking block 10 is reset under the action of the reset spring 14, and the annular gap of the lock column 4 is stuck. The locking sensor block 12 receives the induction and completes the locking action. At this time, the indicator light for successful return of the bike is off.

[0057] 2. When the user needs to return the car, the lock column 4 can be inserted into Figure 6 In the lock hole 11 of the second locking unit 7 of the other bicycle, the locking block 10 is stuck in the annular notch of the lock column 4, and the locking sensor block 12 is sensed to complete the locking action. At this time, the return success indicator light is on, allowing the next bicycle to continue to be parked and returned in series.

[0058] 3. For Figure 6 When returning the first bicycle, if the bicycle falls into the allowed return range defined in advance by the system, the user applies to the system through a mobile terminal such as a mobile phone APP, and the system feedback signal is that the allowed return indicator light is on, allowing it to be parked as the first bicycle. The user can insert the lock column 4 into the lock hole 11 of the first locking unit 6, and the locking sensor block 12 receives the induction to complete the locking and returning action. At this time, the allowed return indicator light goes out, and the successful return indicator light is on, allowing the next bicycle to continue to be parked and returned in series.

[0059] 4. For Figure 6 When returning the first bicycle, if the bicycle does not fall into the allowed return range defined in advance by the system, and the user observes that there are no similar bicycle parking spots around, the user applies to the remote management system through a mobile terminal such as a mobile phone APP. If the remote management system does not allow it to be parked as the first bicycle, the indicator light for allowing the return will not light up, and the remote management system will make a location judgment based on the bicycle GPS module, and calculate the parking radius based on the pre-defined parking radius, and prompt the nearest return point through the APP or voice. For example, the system can define a return point within a radius of 100 meters in a densely populated area, and a return point within a radius of 500 meters in a sparsely populated area, etc., and provide a return direction prompt. The user can go to return the bicycle by himself, and lock the lock column 4 in series into the lock hole 11 of the second locking unit 7 of the previous bicycle that has been returned.

When the bicycle B user locks the lock column of bicycle B into the lock hole of the second locking unit of bicycle A, the locking sensor block of the second locking unit receives the induction, and the RFID radio frequency tag on the lock column of bicycle B and the RFID radio frequency module of bicycle A complete the reading of the corresponding bicycle number information. The remote management system therefore establishes a pairing relationship between the front and rear connected bicycles, determines that the bicycle is returned successfully, stops the timing or billing of the bicycle use, and the successful return indicator light of the indicator light module of bicycle B lights up, and a voice prompt is given that the bicycle is returned successfully, allowing the next bicycle to be connected in series again, and so on.

4. A method for managing shared or public bicycles as claimed in claim 3, Features: The parking locations include default parking locations allowed by the remote management system and new parking locations that are established based on the parking location application submitted by the user in combination with the actual geographical location and calculated through big data; when the remote management system does not agree to establish a new parking location after the user submits an application to return the vehicle, the indicator light for allowing vehicle return will not light up and a voice prompt will be given indicating that vehicle return is not allowed, and the remote management system will feedback information about nearby parking locations that allow vehicle return to the user on the mobile phone or through a voice prompt.

5. A method for managing shared or public bicycles as claimed in claim 3, Features The system also includes a temporary parking method. When the user of bicycle C does not apply for returning the bicycle, the locking column of bicycle C is locked into the locking hole of the first locking unit of bicycle C. After receiving the locking induction, the locking sensing block of the first locking unit determines that bicycle C is temporarily parked, and the return success indicator light of the indicator light module is off, so that the user can judge that the bicycle is temporarily parked, and the system continues to count or charge for the use of the bicycle.

6. A method for managing shared or public bicycles as claimed in claim 5, Features: The temporary parking method also includes a mis-locking state. When bicycle C is temporarily parked, when bicycle D is locked in series with bicycle C, it is determined that the return of bicycle D is invalid and is in a mis-locking state. The control system does not stop the timing or charging of bicycle D. At the same time, the motor of the second locking unit of bicycle C rotates to complete the unlocking action, and the lock column of bicycle D pops out, causing the locking action to fail.

7. A method for managing shared or public bicycles as claimed in claim 3, Features The invention also includes a method for retrieving a bicycle, which is as follows: a user needs to retrieve the bicycle from the back to the front in the order in which the bicycles are locked, by scanning the characteristic information on the bicycles; for the rear bicycle, when the characteristic information is scanned, the remote management system controls the motor of the second locking unit of the lock of the preceding bicycle paired with it to rotate to complete the unlocking action according to the established pairing relationship between the front and rear bicycles; for the leading bicycle and temporary parking, when the characteristic information is scanned, the remote management system controls the motor of the first locking unit of the lock of the leading bicycle and the temporary parking to rotate to complete the unlocking action according to the situation that there is no paired vehicle; for the leading bicycle, when the characteristic information is scanned, the remote management system controls the motor of the first locking unit of the lock of the leading bicycle and the temporary parking to rotate to complete the unlocking action according to the situation that there is no paired vehicle. When the remote management system detects that there is a paired bicycle behind it, the remote management system does not issue an unlocking instruction; for non-first and non-last bicycles, when scanning the feature information, the remote management system determines that there are paired bicycles in front and behind, that is, when there are two paired bicycles at the same time, the remote management system does not issue an unlocking instruction, so as to ensure that users take the bicycles from the back to the front in sequence; the unlocking action includes when the eccentric wheel rotates one circle, the limit sensor receives the induction, the MCU control module controls the motor to stop rotating, and when the lock column is separated from the locking sensor block, the locking sensor block receives the separation induction, and the system starts timing or billing for the use of the bicycle.

8. A method for managing shared or public bicycles as claimed in claim 7, Features: When the first bicycle is set up in a fixed parking lot and is not allowed to be used, the remote management system marks the vehicle number information so that the user cannot unlock it by scanning, and the indicator light module's return permission indicator light and return success indicator light are on at the same time, making it easier for the user to determine that the bicycle is a fixed parking lot.
