Currently, the smart horseshoe locks used in these bicycles have an unreasonable design and incomplete functions, failing to meet the configuration requirements of both traditional and shared bicycles. The locks are located on the outside of the brake body, making them vulnerable to damage; the exposed cable harnesses are numerous, leading to a high failure rate. Therefore, there is an urgent need for those skilled in the art to develop a bicycle central locking wiring harness protection system. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a bicycle central locking wiring harness protection system and a shared bicycle.

[0005] To achieve the above-mentioned objectives, the technical solution provided by this invention is as follows:

[0006] In a first aspect, the present invention provides a single-vehicle central locking wiring harness protection system, the central locking system including a lock body, a central locking device disposed in the lock body and a brake disc, the central locking device including a lock housing and a gear linkage mechanism, a drive mechanism and a wheel movement detection device assembled in the cavity of the lock housing;

[0007] The gate body is provided with a gate head positioning plate and a gate box, and the gate box is provided with a central shaft hole;

[0008] The lock housing is formed with a lead wire groove and a wire outlet groove on one side of the lead wire groove. The gate head positioning plate is disposed on the upper end face of the wire outlet groove, and covers the wire outlet groove to protect the wire bundle led out from the lead wire groove. The gate head positioning plate is provided with a head hole for leading out the wire bundle.

[0009] The wiring harness protection system also includes a curved attachment installed on the inside of the rear swingarm of the bicycle;

The gate head positioning plate 101 and its covered outlet groove 502 are fitted into the curved bracket 203 to form the limiting and wiring harness protection structure of the central locking device.

[0038] The above solution uses a curved connection to position the lock body; at the same time, the cable harness led out from the central locking device directly enters the rear horizontal fork, and the curved connection completely covers and protects the cable harness, thus achieving complete protection of the cable harness.

[0039] To better prevent theft, the rear swingarm 202 and the curved fork 203 are welded together as a single unit.

[0040] The central locking device 3 is located between the gate head positioning plate 101 and the central shaft hole 103, and the installation position of the central locking device 3 is located between the curved support 203 and the rear central shaft 204 and inside the rear horizontal fork 202.

[0041] The following is in conjunction with the appendix Figure 1-9 The embodiments of the present invention will be described in detail below.

The output shaft of the motor 601 is connected to the worm gear 602 for transmission. The worm gear 602 meshes with the large gear of the double gear 1 603, and the small gear of the double gear 1 603 meshes with the large gear of the double gear 2 604. The clutch gear set 606 includes a clutch gear 616 and a clamping gear. The clutch gear has a spring plate 626 and a clutch gear 616, which includes an upper clutch tooth and a lower clutch tooth. The end faces of both the upper and lower clutch teeth are provided with wavy clutch teeth. Under the pressure of the spring plate 626, the upper clutch tooth meshes with the lower clutch tooth through the clutch teeth.

[0049] A wheel motion detection device 8 includes a circuit box 801, a drive circuit board 802, a wheel motion Hall effect sensor 803, a signal switch 804, and a switch triggering boss 805. The drive circuit board 802 and the signal switch 804 are installed inside the circuit box 801. A cable tray 806 is provided on the circuit box 801. The wheel motion Hall effect sensor 803 is installed on one side of the drive circuit board 802, and the signal switch 804 is installed on the side near the rack. The locking signal feedback is realized by the signal switch 804 triggering the switch triggering boss 805 installed on the side of the rack 701.

[0050] The central locking device 3 locks or unlocks by matching the locking pin 704 with the locking groove 402, and the wheel motion Hall signal is fed back by the wheel motion Hall 803 and the wheel motion magnets 404 evenly arranged on the outer circumference of the brake disc 4.

[0051] It also includes a rack and pinion limiting structure disposed within the lock housing 5. The rack and pinion limiting structure includes a stroke limiting mechanism, a first rack and pinion limiting block 504 and a second rack and pinion limiting block 505 disposed on the lock housing 5. Both the first rack and pinion limiting block 504 and the second rack and pinion limiting block 505 are located on one side of the rack 701, and the rack 701 is in contact with both the first rack and pinion limiting block 504 and the second rack and pinion limiting block 505. The stroke limiting structure includes an oblong hole 707 disposed on the rack 701 and a limiting cylindrical boss 506 disposed on the lock housing 5. The oblong hole 707 is adapted to fit on the limiting cylindrical boss 506 so that the rack 701 reciprocates linearly along the length of the slot in the oblong hole 707. The circuit box 801 is made of solid insulating material, and the motor 601 is arranged inside the circuit box 801. The rear horizontal fork 202 and the curved fork 203 are welded together as a single unit. The cable harness inside the central locking device 3 runs along the cable tray 806 and the lead cable tray 501 to the exit cable tray 502, and passes through the head hole of the brake body head positioning plate 101 to enter the rear horizontal fork 202, connecting to the vehicle's central control system to receive control signals. The central locking device 3 is located between the brake body head positioning plate 101 and the central shaft hole 103, and the installation position of the central locking device 3 is between the crank arm 203 and the rear central shaft 204 and inside the rear horizontal fork 202.

[0052] The wheel movement detection device 8 can also be equipped with GPS+Beidou, central locking voltage detection, voice function, remote control function, and Bluetooth function, which can realize high-precision fixed-point return of the vehicle as needed.

[0053] The unlocking process of this invention is as follows: The central control system or controller issues an unlocking command. Upon receiving the command, the drive circuit board 802 causes the motor 601 to reverse and drive the gear linkage mechanism 6, causing the locking pin 704 of the drive mechanism 7 to disengage from the lock groove 402. The switch trigger boss 805 disengages from the trigger point of the signal switch 804, the locking signal changes, and the drive circuit board 802 reports the unlocking completion to the central control system or controller and enters a sleep state, and provides a voice prompt "Vehicle unlocked". The consumer can then use the vehicle normally.

[0054] The locking process of this invention is as follows: The central control system or controller issues a locking command. Upon receiving the command, the drive circuit board 802 causes the motor 601 to rotate forward, driving the gear linkage mechanism 6 so that the locking pin 704 of the drive mechanism 7 is inserted into the locking groove 402. At this time, the wheel motion Hall 803 detects whether the brake disc 4 is rotating.

[0055] (1) If the brake disc 4 is rotating, the Hall signal changes when the magnet 404 passes the wheel Hall 803, indicating that the brake disc 4 is rotating and the consumer is using it. This is a system malfunction. At this time, the drive circuit board 802 does not execute the locking command and gives a voice prompt "Do not lock the bike while riding".

[0056] (2) If the brake disc 4 does not rotate and the wheel drive Hall 803 does not change the detection signal, it means that the vehicle is stationary and the consumer is performing a normal locking operation. The drive circuit board 802 executes the command to make the motor 601 rotate forward and drive the gear linkage mechanism 6 so that the locking pin 704 of the drive mechanism 7 is inserted into the lock groove 402. At the same time, the switch trigger boss 805 on the rack 701 moves closer to the position of the signal switch 804. The locking signal feedback is achieved through the triggering of the signal switch 804 and the switch trigger boss 805. The drive circuit board 802 reports to the central control system or controller that the locking is completed and enters the sleep state, and gives a voice prompt "Return successful".

[0057] Standardize the implementation process of parking:

[0058] (1) Consumers send a car return request to the sharing platform through the mobile APP. The sharing platform sends a car return instruction to the central locking system. The GPS and Beidou positioning of the drive circuit board 802 finds that the car is not within the electronic fence or the designated car return point. It sends a "non-standard parking" signal to the sharing platform, does not execute the lock command, and gives a voice prompt "Please park properly at the car return point".

[0059] (2) Consumers send a vehicle return request to the sharing platform via mobile APP. The sharing platform sends a vehicle return instruction to the central locking system, which drives the GPS and Beidou positioning of the circuit board 802 to locate the vehicle within the electronic fence or the designated return point, and drives the circuit board 802 to perform the aforementioned locking process.

[0060] Therefore, the lock can be remotely operated by the sharing platform, can communicate with the central locking device in real time, and can monitor the lock's open / closed status and the rear wheel's rotation status. GPS and Beidou provide reliable hardware support for electronic fence technology, providing technical assurance for governments and enterprises to solve the problem of disorderly parking of shared bicycles and enable consumers to park in a standardized manner, which is more in line with the operation mode of smart products.

[0061] The above content is an example and description of the present invention, but it does not mean that the advantages that the present invention can obtain are limited thereto. Any simple changes to the structure that may be made in the practice of the present invention, and / or one or more of the advantages achieved in some embodiments, are within the protection scope of this application.
