The invention discloses a bicycle intelligent multi-functional parking device based on internet of things. The bicycle intelligent multi-functional parking device based on the internet of things comprises a parking frame, and a plurality groups of parking supports are arranged in the parking frame and are sequentially distributed in the horizontal direction; each group of parking support comprises at least two parking rails which are sequentially distributed in the vertical direction, the end parts of the parking rails are provided with supporting brackets which adopt U-shaped structure, and the supporting brackets are parallel to the parking rails to extend; the supporting brackets and the parking rails are connected through supporting rod pieces, and electric bicycle locks are arranged on the supporting rod pieces; and each parking rail is internally connected to the parking frame through lifting devices, width of the multiple parking rails in any group of parking support is sequentially increased from top to bottom in the vertical direction. According to the bicycle intelligent multi-functional parking device based on the internet of things, management for public bicycle is remarkably improved in an effective space, and thus utilizing efficiency is improved.
