The invention relates to the technical field of smart cities, and discloses an automatic folding solar panel new energy street lamp for smart cities, and the new energy street lamp comprises a main body, a rubber block is movably connected to the outer side of a base, and a metal frame is movably connected to the middle of the base. According to the automatic folding solar panel new energy streetlamp for smart cities, when a light panel is about to be broken off when encountering strong wind, a main shaft jolts up and down under the action of linkage force, a metal block pressurizes a balancerod to operate, a through pipe pushes a middle part to operate synchronously, and the middle part pushes a metal strip to operate; the metal strip pushes a clamping block to operate towards the outerside, and a rubber block locks an adjusting plate to operate, so that the force of the light panel at the upper end is adjusted, bending of the light panel is stopped, the light panel is prevented from being broken off due to excessive force, the force is completely disassembled and decomposed to equipment, certain economic loss is retrieved, meanwhile, electric energy is supplemented, and the lighting effect is improved. And hidden traffic hazards are prevented.
