In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings:

referring to fig. 1 and 2, fig. 1 is a reference diagram illustrating a use state of a brake lock of an embodiment of an anti-mislocking system, and fig. 2 is a schematic diagram illustrating an internal structure of the brake lock of the embodiment of the anti-mislocking system. The anti-false-locking brake lock in the embodiment comprises a lock body 1, a lock shell member 2, a lock catch member 3, a lock catch elastic member 4, an elastic traction member 5 and a driving mechanism 6, wherein the lock body 1 is sleeved on a hub 100 and rotates along with the hub 100, and the lock shell member 2 is arranged adjacent to the lock body 1. The lock catch piece 3 is rotatably arranged in the lock shell piece 2, a lock opening 11 is formed in the lock body 1, and one end, close to the lock body piece 1, of the lock catch piece 3 is matched with the lock opening 11. The catch spring 4 is connected to the catch part 3 and acts on the catch part 3 such that the catch part 3 is rotated towards the locking opening 11 of the lock body 1. One end of the elastic traction piece 5 is connected with the locking piece 3. The driving mechanism 6 is arranged in the lock shell member 2 and is connected with the other end of the elastic traction member 5. When unlocking, the driving mechanism 6 drives the elastic traction piece 5 to move, and the elastic traction piece 5 pulls the lock catch piece 3 to rotate towards the direction far away from the lock opening 11; when the lock is closed, the driving mechanism 6 is driven reversely, the traction force of the elastic traction piece 5 on the lock catch piece 3 disappears, the lock catch elastic piece 4 drives the lock catch piece 3 to move towards the lock opening 11, and when the rotating speed of the lock body 1 is greater than the preset speed, the lock catch piece 3 cannot be clamped into the lock opening 11 and cannot stop the lock body 1.

When a locking command is received, if the rotating speed of the lock body 1 is lower than a preset speed, the brake lock performs a locking action, the lock catch elastic piece 4 pushes the lock catch piece 3 to be clamped into the lock notch 11, the lock body 1 stops rotating, and therefore the hub 100 also stops rotating; when the lock is unlocked, the output end of the driving mechanism 6 drives the elastic traction piece 5 to move, the elastic traction piece 5 pulls the locking piece 3, the acting force of the driving mechanism 6 and the elastic traction piece 5 on the locking piece 3 is greater than the acting force of the locking elastic piece 4 on the locking piece 3, so the elastic traction piece 5 drives the locking piece 3 to move towards the direction far away from the lock opening 11, and after the locking piece 3 is separated out from the lock opening 11, the lock body 1 and the hub 100 can freely rotate.

It should be noted that the preset speed mentioned in the present embodiment refers to a running speed at which the bicycle or the electric vehicle stops suddenly during running, but does not cause great damage to the user; the preset speed is not a fixed value and can be set according to requirements, for example, the preset speed can be 4km/h, 5km/h or 6km/h, and the structure of the brake lock is correspondingly changed in an adaptive manner.

To sum up: the brake lock of mistake proofing lock in this application passes through the lock body, lock shell spare, the hasp elastic component, elasticity tractive spare and actuating mechanism's cooperation is used, the lock body is connected to on the wheel hub, when the speed of traveling is greater than predetermined speed, because hasp spare is shorter with fore shaft contact time, can't carry out the joint, can not carry out the locking to the lock body, therefore even the brake lock receives the wrong instruction or breaks down, also can't lock at the fast in-process of traveling, prevent the damage that proruption locking brought the user, greatly reduced potential safety hazard. On the contrary, when the speed of traveling is less than when predetermineeing speed, hasp elastic component continuously promotes hasp piece butt lock body, and hasp piece is longer with fore shaft contact time, and the fore shaft on hasp piece and the lock body has sufficient time to carry out the joint to can carry out the locking to the lock body. In addition, the locking and unlocking action of the locking piece is realized through the elastic parts such as the locking elastic piece and the elastic traction piece, so that even if the locking piece is not separated from the lock opening due to external force and the like during unlocking, the driving mechanism can pull the elastic traction piece to carry out unlocking action, and when the external force applied to the locking piece disappears, the elastic traction piece can quickly pull the locking piece into the lock shell piece, so that the unlocking is successful; when the lock is closed, even if the lock catch piece cannot be locked due to the fact that the running speed exceeds the preset speed, the driving mechanism can normally run, when the running speed is reduced to be lower than the preset speed, the lock catch elastic piece pushes the lock catch piece to be clamped with the lock opening, and the lock is closed successfully.
