Description

A shared bicycle smart lock

technical field

The utility model relates to the field of shared leasing, in particular to an intelligent lock for shared bicycles.

Background technique

Shared bicycles are a kind of rental public bicycles that can be borrowed and parked by users after installing smart locks on ordinary bicycles, and the key equipment is smart locks. The current smart lock for public bicycles is a switch lock that receives system commands, that is, the user scans the QR code of the vehicle's identity information or enters the vehicle number through a specific mobile phone application, and initiates a request to the system to use the vehicle. The GPRS/GSM communication network sends an instruction to the smart car lock device of the vehicle, unlocks the lock and starts billing on time. After the user finishes using the vehicle, close the car lock, the device sends an instruction to the system, and the system ends the user's charging. In the process of receiving system commands, the smart car lock device is seriously affected by the communication method. In areas with weak GPRS/GSM signals, it causes problems such as slow unlocking and delay in ending billing, which affects user experience. Restricted by manpower and material resources and other scheduling management resources, shared bicycles generally delineate the scope of use, and seldom allow users to ride to the suburbs or outside the city. However, the current equipment does not have a prompt function, and users may blindly ride out of the scope of use, which makes it difficult for the operating company to manage vehicles. . Users may ride at a higher speed on roads with good road conditions or downhill roads, causing certain safety hazards.
