A rechargeable intelligent rear wheel lock for shared bicycles

technical field

The invention relates to a rechargeable intelligent rear wheel lock for shared bicycles, belonging to the technical field of public bicycles.

Background technique

In today's society, environmental governance is the most important topic, among which air governance is the primary task. Environmental protection travel is one of the important ways to solve environmental problems. In daily life, the most environmentally friendly way to travel for short distances is bicycles. Bicycles, especially mountain bikes, road bikes, and bicycles with special materials are becoming more and more popular among young people. At the same time, bicycles are also It has gradually been 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 go to work or shoppers prefer to use bicycles. , but private bicycles will have a series of problems such as theft and parking, so urban 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 of the issues to consider is to ensure the safety of bicycles, so a smart, safe and fast lock is in urgent need.

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

Although there are some smart car locks on the market to meet the corresponding needs, the biggest problem is the power supply. One is to use a 5th 1.5V battery for power supply. When the power is used up, the motor in it will not be able to rotate. Naturally The ground car lock cannot be opened. When many shared bicycles are put into the market, the replacement of batteries and timely maintenance will waste a lot of money and manpower, resulting in waste of resources and low utilization of bicycles. Another is to use solar energy. The charging method 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 have made a power generation device combined with the generator at the rear axle to supply power to the rechargeable battery, which can solve the current problem very well.

Therefore, there is a need to provide an automatic bicycle lock with a sturdy structure, good anti-theft performance and rechargeable properties, so as to improve the safety, reliability, convenience and practicability of the bicycle lock.
