Wind-resistant billboard

Abstract

The invention discloses a wind-resistant billboard, including a billboard main board and a bottom plate. A folding mechanism is arranged on the bottom plate, A mounting plate is arranged on the bottomplate, the mounting plate is provided with a wind sensor for driving the folding mechanism, A billboard main board includes a drive assembly and a plurality of main board assemblies, A drive assemblyand a plurality of main board assemblies are provided with gears, gears are used to engage adjacent gears, A main board of that billboard is also provided with a plurality of first hinge plates, thefirst hinge plate is used for connecting the gears which are meshed with each other. The folding mechanism comprises a rotating electric machine, the output end of the rotating electric machine is connected with a cylinder, A drive wheel is sleeved on the barrel, A passive wheel is arranged on the side of the drive assembly facing the driving wheel, When the detected wind force is greater than themaximum wind force that the billboard can bear, the main board of the billboard is folded so as to reduce the stress area and improve the wind resistance capability.
