Abstract

The invention relates to the technical field of new energy, and discloses a public sunshade capable of being automatically folded and unfolded in windy weather. The public sunshade comprises a supportcolumn, a shell is fixedly mounted at the top of the support column, a first rotating shaft is rotatably mounted on the inner bottom wall of the shell, and a shaft coupling is fixedly mounted at thetop of the first rotating shaft; and a second rotating shaft is fixedly installed at the top of the shaft coupling, a windmill is fixedly installed at the top of the second rotating shaft, a wire frame is fixedly installed on the outer side of the first rotating shaft, and a first permanent magnet is fixedly installed on the left wall in the shell. According to the public sunshade capable of beingautomatically folded and unfolded in the strong wind weather, the public sunshade can be automatically folded in the strong wind weather and can be automatically unfolded when the strong wind weatherstops, the public sunshade is prevented from being damaged by impact of strong wind, resource waste is reduced, and meanwhile the situation that the appearance and functions of the damaged public sunshade are affected, consequently the mood of people is damaged is avoided, meanwhile, the structure is simple, and a sensor and an external power supply are not needed.
