A rechargeable intelligent rear wheel lock for shared bicycles

technical field

The utility model relates to a rechargeable intelligent rear wheel lock for shared bicycles, which belongs to the technical field of public bicycles.

Background technique

In today's society, environmental governance is the most important issue, among which air governance is the top priority. And environmental protection travel is one of the important ways to solve environmental protection problems. In daily life, the most environmentally friendly way of short-distance travel is bicycles. Bicycles, especially mountain bikes, road bikes, and special material bicycles are becoming more and more popular among young people. At the same time, bicycles are also It is gradually used by people of all ages as an exercise tool for physical fitness.

With the development of the city and the improvement of people's living standards, more and more family cars in the city have undoubtedly caused environmental pollution and urban congestion. In the city, many people who go to work or shop at close distances prefer to use bicycles. , but there will be a series of problems such as theft and parking of private bicycles, so the city shared bicycles came into being, alleviating people's various contradictions, and also proposed a good solution, but the emergence of shared bicycles must be One problem to consider is to ensure the safety of the bicycle, so a kind of intelligent, safe and fast lock is in urgent demand.

Yet all there is common shortcoming in the bicycle lock on the market at present---safety reliability is not strong, and existing bicycle lock is nothing more than following several: the first kind is traditional cable (iron chain) pure mechanical lock; The second is a one-piece cable mechanical lock installed on the seat shaft; these two bicycle locks are the most likely to be stolen because of their simple structure, and their strength is always difficult to meet the anti-theft requirements due to size and cost. Just an iron wire and a pair of steel shears can be easily unlocked, which greatly reduces its safety and reliability.

Although there are some smart car locks on the market that meet the corresponding needs, the biggest problem is the power supply. One is powered by a 1.5V battery on the 5th. When the power is used up, the motor in it will not be able to rotate. The lock of the ground bike cannot be opened. When there are many shared bicycles in the market, the battery replacement and timely maintenance will waste a lot of money and manpower, resulting in a waste of resources and a low utilization rate of bicycles. Another is to use solar energy. The way of charging continuously provides energy for the battery. Although the problem of limited battery power is solved, the solar panel is fragile and the power supply is unreliable. In order to solve this problem, we made a power generation device combining the shaft and the generator at the rear axle to supply power to the rechargeable battery. This method can solve the current problem very well.

Therefore, it is necessary to provide a kind of automatic bicycle lock with firm structure, good anti-theft performance and rechargeable, so as to improve the safety, reliability, convenience and practicability of the bicycle lock.
