Referring to fig. 3 and 4, fig. 3 is a structural schematic diagram of a braking system applied to locking a hub in the embodiment; fig. 4 is a schematic structural diagram of a part of a brake system applied to locking a hub in the embodiment. The locking driving mechanism 2 comprises a carrying box 21, a driving assembly 22, a locking assembly 23 and a guiding assembly 24, wherein the guiding assembly 24 comprises two guiding carrying pieces 241 and a guiding piece 242.

The restoring members 243 are springs in the present embodiment, and the number thereof is the same as that of the guide bearings 241. One end of the restoring member 243 abuts against the guide member 242, and the other end thereof abuts against the latch unit 23. When the driving assembly 22 drives the locking assembly 23 to be locked, the locking assembly 23 drives the guide member 242 to compress the resetting member 243, so as to provide a buffering effect for the locking assembly 23, avoid the locking assembly 23 from moving suddenly, and damage caused by violent collision, when the driving assembly 22 drives the locking assembly 23 to be unlocked, the resetting member 243 is restored, and acts on the guide member 242, and the guide member 242 drives the locking assembly 23, so that the locking assembly 23 is restored to the initial position.

Referring to fig. 5, fig. 5 is another partial structural schematic diagram of a braking system structure applied to locking a hub in the embodiment. The drive assembly 22 includes a drive member 221 and a transmission member 222. The output end of the driving element 221 is connected to one end of the transmission element 222, and the transmission element 222 transmits the power of the driving element 221 to the vehicle locking assembly 23. When the vehicle is locked, the driving element 221 is driven in the forward direction, and the vehicle locking assembly 23 is driven to move towards the vehicle locking mechanism 3 through the driving element 222 and acts on the vehicle locking mechanism 3 to complete locking; when unlocking, the driving element 221 drives in reverse direction, and the driving element 222 drives the locking vehicle assembly 23 to reset, so as to complete unlocking. The driving member 221 is a motor in this embodiment.

Further, the transmission member 222 includes a gear transmission sub-member 2221 and a screw transmission sub-member 2222. The gear transmission sub-assembly 2221 transmits the power of the driving member 221 to the screw transmission sub-assembly 2222, and the screw transmission sub-assembly 2222 converts the power from a rotary form into a linear motion form, and then acts on the lock assembly 23 to drive the lock assembly 23 to linearly move.

By increasing the number of gears, a long-distance transmission is realized, and compared with the mode of using a larger gear, the space utilization rate is higher, and meanwhile, the bearing box 21 can be thinner. The nut gear 22212 is screwed with the lead screw transmission sub-part 2222, and the lead screw transmission sub-part 2222 is slidably disposed in the bearing box 21.

One elastic end of the elastic sub-part 2223 abuts against the screw rod transmission sub-part 2222, and the other end abuts against the vehicle locking assembly 23. When the vehicle is locked, the screw rod transmission sub-element 2222 moves linearly towards the direction close to the vehicle locking assembly 23, the screw rod transmission sub-element 2222 compresses the elastic sub-element 2223, the elastic sub-element 2223 acts on the vehicle locking assembly 23, and the vehicle locking assembly 23 moves linearly towards the vehicle locking mechanism 3 and acts on the vehicle locking mechanism 3. If the car locking assembly 23 moves to the car locking mechanism 3 but does not fall into the preset position, when the movement is blocked, the screw rod transmission sub-assembly 2222 continues to advance, which will cause the damage of the car locking assembly 23; the elastic sub-part 2223 can provide a buffering effect for the car locking assembly 23, and when the screw rod transmission sub-part 2222 continues to advance, the kinetic energy of the screw rod transmission sub-part 2222 is converted into elastic potential energy of the elastic sub-part 2223, so that the car locking assembly 23 is prevented from continuing to advance towards the car locking mechanism 3 and being damaged due to collision. The resilient member 2223 is a spring in this embodiment.

The elastic sub-element 2223 is sleeved on the guiding and bearing sub-element 2224, one end of the guiding and bearing sub-element 2224 is arranged at one end of the screw rod transmission sub-element (2222) acting on the vehicle locking assembly 23, and the other end thereof is movably arranged in the vehicle locking assembly 23. The guiding and bearing sub-element 2224 provides support for the elastic sub-element 2223, so as to ensure that the acting direction of the elastic sub-element 2223 is the same as the moving direction of the vehicle locking assembly 23, thereby improving the efficiency of power transmission.

Preferably, the locking driving mechanism 2 further comprises a detection assembly 25. The detecting assembly 25 is fixedly disposed in the carrying case 21 and is located on a moving path of the guide 242. When the bicycle is locked, the guide piece 242 linearly moves along with the bicycle locking assembly 23, the bicycle locking assembly 23 acts on the bicycle locking mechanism 3, the bicycle is locked, meanwhile, the guide piece 242 abuts against the detection assembly 25 to trigger the detection assembly 25 to work, the detection assembly 25 identifies that the bicycle is in a locked state, and sends an instruction to the driving piece 221 to stop forward driving; when the lock is unlocked, the lock body assembly 23 and the guide 242 are restored to the initial positions, the guide 242 is no longer abutted against the detection assembly 25, and the detection assembly 25 recognizes that the bicycle is unlocked.

Referring to fig. 6, fig. 6 is a schematic structural diagram of a high-speed anti-lock assembly in an embodiment. Referring back to fig. 1, the locking mechanism 3 includes a locking female member 31 and a high-speed anti-locking assembly 32. The high-speed anti-lock assembly 32 is sleeved on the lock nut 31. The high speed anti-lock assembly 32 includes an anti-lock body 321 and a plurality of high speed restrictions 322; the anti-lock main body 321 is sequentially provided with a plurality of locking grooves 3211 at intervals along the circumferential direction of the anti-lock main body 321, the plurality of high-speed limiting parts 322 are respectively in one-to-one correspondence with the plurality of locking grooves 3211, one end of the high-speed limiting part 322 is connected with the anti-lock main body 321, the other end of the high-speed limiting part 322 extends and tilts towards the upper side of the locking grooves 3211 to form tilting ends, and the tilting directions of the tilting ends of the plurality of high-speed limiting parts 322 are the same. The locking grooves 3211 are strip-shaped through openings formed in the anti-lock body 321, and the plurality of locking grooves 3211 are arranged in sequence along the circumference of the anti-lock body 321. Specifically, the high-speed limiting part 322 is a strip-shaped plate with a radian, the high-speed limiting part 322 is elastic and is located outside the vehicle locking groove 3211, one end of the high-speed limiting part 322 is connected with one end of the vehicle locking groove 3211, the other end of the high-speed limiting part 322 tilts to form a tilting end, the tilting end extends above the other end of the vehicle locking groove 3211, and the other end of the vehicle locking groove 3211 leaks from the tilting end of the high-speed limiting part 322.

In a specific application, when the bicycle runs, the locking female member 31 and the high-speed anti-locking assembly 32 rotate together. When the high-speed anti-lock assembly 32 is in a high-speed rotation state, the high-speed limiting pieces 322 rotate at a high speed, the action end of the locking assembly 23 is pulled away by the high-speed limiting pieces 322 rotating at a high speed, the action end of the locking assembly 23 can only act on the high-speed limiting pieces 322, and after the rotation speed of the anti-lock body 321 is reduced, the action end of the locking assembly 23 falls into the locking groove 3211, and passes through the anti-lock body 321 to act on the locking female member 31 to complete locking. The safety accident that the personnel of riding can not react in time and cause because of the sudden locking action under the state that the bicycle is traveling at a high speed is avoided. When the high-speed limiting piece 322 continuously shifts the locking car assembly 23, the high-speed limiting piece 322 and the locking car assembly 23 are easily damaged only by the elasticity of the high-speed limiting piece 322. The provision of the resilient member 2223 enables the latch assembly 23 to cushion when stressed to reduce the risk of damage and increase the safety of the structure. The high speed anti-lock assembly 32 in this embodiment is in a high speed rotation state when the riding speed is higher than three kilometers per hour.

Specifically, the brake mechanism 4 includes a brake cable (not shown), a mounting post 41, a tension spring 42, a cable plate 43, a cable post (not shown), and a brake pad 44.
