[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0028] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] For an example, please refer to... Figures 1-5 A locking structure for shared bicycles includes a main shaft 1 and a hub 101 mounted on the main shaft 1. A locking element is provided between the hub 101 and the main shaft 1, and the locking element is located inside the hub 101. The locking element includes a lock disc 2 bolted to the hub 101. The lock disc 2 has several insertion holes 201. A fixing plate 202 is fixedly mounted on the main shaft 1. A mounting seat 203 is bolted to the side of the fixing plate 202 near the lock disc 2. A push-pull electromagnetic lock 204 is mounted on the mounting seat 203. The locking rod of the push-pull electromagnetic lock 204 is inserted into one of the insertion holes 201. By placing the locking element inside the hub 101, the locking element is protected by the hub 101, which can effectively reduce the direct damage of external environmental factors to the locking element, reduce the failure rate of the locking element caused by environmental factors, and improve the service life and reliability of the shared bicycle.

[0031] The push-pull electromagnetic lock 204 is an existing structure. Its locking rod is pushed out by the action of the spring. Therefore, when the locking rod of the push-pull electromagnetic lock 204 is aligned with the socket 201, it can be directly inserted into the socket 201. If it is not aligned with the socket 201, the locking rod of the push-pull electromagnetic lock 204 will first contact the lock disc 2. When the vehicle is pushed, the hub 101 drives the lock disc 2 to rotate. When the locking rod of the push-pull electromagnetic lock 204 is aligned with the socket 201, it will be inserted into the socket 201 to lock.

[0032] Furthermore, a speed measuring element is provided between the fixing plate 202 and the locking disc 2. The speed measuring element is used to detect the rotation speed of the hub 101, thereby confirming whether the shared bicycle is being ridden, so as to prevent locking while riding.

[0033] Furthermore, the speed measuring component includes several magnets 207 disposed on the side of the lock disc 2 near the push-pull electromagnetic lock 204. The speed measuring component also includes a circuit board 205 mounted on the fixed plate 202. A Hall sensor 206 is connected to the side of the circuit board 205 near the lock disc 2. The magnets 207 and the lock disc 2 rotate with the rotation of the hub 101. The magnets 207 are on the rotational trajectory of the Hall sensor 206. The rotational speed of the hub 101 can be detected by the cooperation of the Hall sensor 206 and the magnets 207.

[0034] Furthermore, an end cap 105 is bolted to one end of the hub 101 near the bearing 102. The hub 101 and the end cap 105 work together to protect components such as the push-pull electromagnetic lock 204, circuit board 205, Hall sensor 206, magnet 207, and lock disc 2.

[0035] Furthermore, a retaining ring 106 is fixedly connected to one end of the hub 101 near the end cap 105. The outer surface of the retaining ring 106 is inserted into the inner wall of the end cap 105. The retaining ring 106 can reinforce the connection between the end cap 105 and the hub 101.

[0036] Furthermore, a bearing 102 is provided between the inner wall of the hub 101 and the outer surface of the spindle 1, and a bearing 102 is also provided between the end cap 105 and the outer surface of the spindle 1. The bearing 102 and the spindle 1 cooperate with each other to support the hub 101.

[0037] Furthermore, two anti-rotation plates 103 are fitted on the outer surface of the spindle 1, and the two anti-rotation plates 103 are respectively located on the side of the two bearings 102 that are far apart from each other.

[0038] Furthermore, the outer surface of the spindle 1 is threaded with two nuts 104, which are located on opposite sides of the two bearings 102. The nuts 104 can limit the rotation of the anti-rotation plate 103.

[0039] Furthermore, the main shaft 1 is centrally located, and a connecting port 3 is also provided on the main shaft 1, which is connected to the hollow area of ​​the main shaft 1.

[0040] Furthermore, the push-pull electromagnetic lock 204 and the Hall sensor 206 are both connected to the circuit board 205. The circuit board 205 is connected to a waterproof line, which passes through the connecting port 3 and the main shaft 1 and extends to the outside of the main shaft 1. The circuit board 205 is connected to the main controller of the shared bicycle through the waterproof line, and receives the unlock command after the user successfully scans the code, and controls the locking lever of the push-pull electromagnetic lock 204 to retract to achieve unlocking. After the ride ends, the main controller sends a locking command, and the push-pull electromagnetic lock 204 cooperates with the socket 201 to lock. The gap between the waterproof line and the connecting port 3 can be filled and sealed with glue to prevent rainwater from entering through the gap.
