In response to the call of the country to promote green and low-carbon, the team developed a fully automatic bicycle parking device powered by solar energy. This device can be used to park shared bicycles and family bicycles, which can not only effectively solve the problem of large parking area of shared bicycles and affecting the appearance of the city, but also retain the convenience of sharing bicycles when they are parked, so as to encourage people to travel green. The space utilization rate of the device is high, and the bicycle is vertically suspended and stacked layer by layer by using cage parking frame, which greatly reduces the occupied area. Solar power supply is green and pollution-free. Compared with the energy supply mode of "manual charging and regular maintenance", solar power supply basically avoids the emission of pollutants in power generation and charging. The device is highly adaptable and can be put into operation in a wide range. Solar power supply makes the device free from the limitation of power supply conditions, thus applicable to various application scenarios, any place with sufficient sunshine can be put into use; In addition, the cost control of the device has strong operability, and the cage parking frame can be put into use by relying on street lamps and telegraph poles after modification. The adoption of this device improves the storage environment quality of bicycles to a certain extent, the solar panel shed can play the effect of shading and rain, and the storage mode of vertical suspension of bicycles further strengthens the protection effect.
