Description

A kind of bicycle front tube bluetooth lock, bluetooth lock system and method for unlocking the bicycle

technical field

The invention relates to the technical field of bicycle locks, in particular to a bicycle front pipe bluetooth lock, a bluetooth lock system and a method for unlocking a bicycle.

Background technique

As everyone knows, the bicycle lock is one of the important parts of the bicycle, and the lock mainly plays the role of anti-theft. At present, traditional bicycles (including mountain bikes, road bikes, etc.) are generally equipped with mechanical locks. When the user parks the bicycle somewhere, the bicycle is locked by the mechanical lock on the bicycle, so as to To achieve the purpose of anti-theft. When the user uses the bicycle again, the mechanical lock is unlocked by using the mechanical key matched with the mechanical lock. Because they are all unlocked with a key, the lock hole is exposed, and it is easy to be pried open or damaged. Outdoors, rainwater and sundries enter the lock hole, causing the lock to fail to open.

As can be seen from the above, the current bicycle lockset mainly has the following problems:

(1) The user must carry the mechanical key matched with the mechanical lock every time he uses the bicycle, and since the mechanical key is generally made of metal, the travel burden of the user is increased;

(2) When the user parks the bicycle, it is necessary to manually trigger the locking action, which increases the user's operation steps. In particular, when the user has an emergency and forgets to lock the bicycle by using a mechanical lock, it may Can cause bicycle to be stolen, thereby bring property loss to user.

In addition, Chinese patent CN201410506354 discloses a bicycle lock with bluetooth function. A deadbolt is provided in the casing, and a cavity structure is formed at the rear of the deadbolt. A deadbolt reset spring and a deadbolt sliding There is an electromagnet connected to the end of the bolt slide rod, a bolt stop plate on the top and bottom of the electromagnet, a bolt stop plate slide rod is connected between the two bolt stop plates, and a bolt stop plate slide rod is connected between the two bolt stop plates. The stop plate slide bar is provided with a deadbolt stop plate return spring, a partition is provided at the end of the electromagnet, and a bluetooth circuit board is provided on the other side of the partition; a switch is provided on the battery compartment, and the switch passes through a wire Connect with bluetooth board. This patent application adopts a combination structure of a bluetooth circuit board and an electromagnet, and the electromagnet is notified from the bluetooth circuit board to drive the deadbolt to move to realize the unlocking or locking function. But after careful study, the bicycle lock with Bluetooth function is also an external lock, which can be easily cut off, and when unlocking, people need to pull out the lock lever, so the operability is not good and the safety is not high.
