This is a children's toy design with energy storage.
In many poor areas today, energy supply is a big problem. People don't have the concept of energy storage. At night, people can't meet the lighting demand because of the lack of energy supply.At the same time, children in poor areas lack toys for their play, and childhood is boring.Energy storage is performed by eccentricity movements that children produce while using toys.At night, the user twists the toy, and the toy function is converted into a lighting fixture function to meet the needs of the user's night light.
