Referring to fig. 1-4, a public sunshade capable of being automatically folded and unfolded in strong wind weather comprises a support 1, a shell 2 is fixedly installed at the top of the support 1, a first rotating shaft 6 is rotatably installed on the inner bottom wall of the shell 2, a coupler 5 is fixedly installed at the top of the first rotating shaft 6, a second rotating shaft 3 is fixedly installed at the top of the coupler 5, a windmill 4 is fixedly installed at the top of the second rotating shaft 3, a wire frame 7 is fixedly installed on the outer side of the first rotating shaft 6, a first permanent magnet 8 is fixedly installed on the left wall inside the shell 2, and a second permanent magnet 9 is fixedly installed on the right wall inside the shell 2;

the inner part of the pillar 1 is provided with a first cavity 10, the inner top wall of the pillar 1 is fixedly provided with electromagnets 11, the left side and the right side of the pillar 1 are symmetrically provided with chutes 12, the chutes 12 are slidably provided with first sliders 13, one side of each first slider 13, which is far away from the first cavity 10, is fixedly provided with a lower disc 19, the outer side of each lower disc 19 is rotatably provided with a first connecting rod 20, one end of each first connecting rod 20, which is far away from the lower disc 19, is hinged with a second connecting rod 21, no less than four pairs of the first connecting rods 20 and the second connecting rods 21 are uniformly distributed on the outer side of the pillar 1, the top of each second connecting rod 21 is provided with umbrella cloth, the upper end of the pillar 1 is fixedly provided with a ring 22, one side of each first slider 13, which is far away from the lower disc 19, is fixedly provided with a disc 14, the bottom of the disc 14 is fixedly provided with a first, the right wall inside the pillar 1 is provided with a limit mechanism 17.

The limiting mechanism 17 includes a first groove 174, a second spring 173 is fixedly mounted on the left side of the first groove 174, a second slider 172 is fixedly mounted on one end of the second spring 173 far away from the first groove 174, the second slider 172 is slidably mounted inside the first groove 174, and a projection 171 is fixedly mounted on the left side of the second slider 172. The protrusion 171 is formed in a hemispherical shape, the second recess 18 is formed in a hemispherical shape, the radius of the second recess 18 is greater than that of the protrusion 171, and the upper end of the second link 21 is hinged to the ring 22.

The working principle is as follows: when wind starts, the windmill 4 drives the wire frame 7 to rotate through the second rotating shaft 3, the coupler 5 and the first rotating shaft 6. Because wire frame 7 the left side and the right all have the permanent magnet, first permanent magnet 8 is semi-circular, and first permanent magnet 8' S right-hand member is the N utmost point, and second permanent magnet 9 is semi-circular, and the left end of second permanent magnet 9 is the S utmost point, and installs the wire on the wire frame 7, and the coil both ends of electro-magnet 11 are connected at the both ends of wire. Therefore, the wire frame 7 performs cutting magnetic induction wire movement in windy weather, and induced current flows through the electromagnet 11, so that the electromagnet 11 has magnetism. Since the blades of the windmill 4 are uniformly distributed on the outer side of the second rotating shaft 3, the windmill 4 can receive the rotating force provided by wind from four sides, the rotation direction of the windmill is only related to the inclined angle of the blades, so that the windmill of the invention has only one rotation direction, the current generated by the windmill 4 driving the wire frame 7 to cut the magnetic induction wire is only one direction, the lower end of the electromagnet 11 can be made to be N-pole by adjusting the winding direction of the coil, and the magnetic strength of the electromagnet 11 is in positive correlation with the rotating speed of the windmill 4.

Because the upper end of the third permanent magnet 16 is an N pole, when wind starts, the third permanent magnet 16 can receive gravity, repulsive force of the magnet and resistance of the limiting mechanism 17, when wind power is high, the rotating speed of the windmill 4 is high, the magnetism of the electromagnet 11 is strong, when the gravity and the repulsive force of the magnet received by the third permanent magnet 16 are greater than the resistance of the limiting mechanism 17, the third permanent magnet 16 can break through the limiting mechanism 17 to move downwards, the convex block 171 and the second sliding block 172 of the limiting mechanism 17 move rightwards, the second spring 173 compresses, the third permanent magnet 16 drives the disc 14 to move downwards, the first spring 15 compresses, the disc 14 drives the lower disc 19 to move downwards through the first sliding block 13, the lower disc 19 drives the umbrella cloth to be folded through the first connecting rod 20 and the second connecting rod 21, and the effect of automatic folding of the common sunshade umbrella is realized in strong wind weather.

When the umbrella cloth is completely folded, the third permanent magnet 16 moves to the lower end of the limiting mechanism 17, the second spring 173 is restored, and the second spring 173 drives the lug 171 to move leftwards through the second sliding block 172.

When the windy weather stops, the windmill 4 stops rotating, the wire frame 7 stops cutting the magnetic induction wire, no current flows in a coil of the electromagnet 11, the magnetism of the electromagnet 11 disappears, the third permanent magnet 16 is not subjected to the magnetic force of the magnet any more, the disc 14 moves upwards under the elastic force of the first spring 15, the disc 14 drives the lower disc 19 to move upwards through the first sliding block 13, the lower disc 19 drives the sunshade cloth to open through the first connecting rod 20 and the second connecting rod 21, and the effect that the public sunshade umbrella is automatically opened after the windy weather stops is achieved.

In conclusion, the automatic folding and unfolding public sunshade umbrella in the strong wind weather achieves the effects that the sunshade umbrella is automatically folded in the strong wind weather and automatically unfolded in the strong wind weather, the public sunshade umbrella is prevented from being damaged due to the impact of the strong wind, the waste of resources is reduced, meanwhile, the phenomenon that the mood of people is damaged due to the fact that the appearance and the function of the damaged public sunshade umbrella are affected is avoided, and meanwhile, the structure is simple, and a sensor and an external power supply are not needed. The wire is driven by wind power to cut the magnetic induction wire to generate induction current, so that a device in the public sunshade umbrella can be automatically started according to the wind power without a sensor and an external power supply. Through the repulsion of the third permanent magnet 16 and the electromagnet 11 and the first spring 15, the sunshade umbrella realizes automatic folding in the strong wind weather and automatic release in the strong wind weather, thereby avoiding the damage of the public sunshade umbrella caused by the impact of the strong wind, reducing the resource waste, and avoiding the damage of people caused by the influence on the appearance and the function of the damaged public sunshade umbrella. By utilizing the limiting mechanism 17, the public sunshade umbrella can be automatically folded only when the wind power is high, the phenomenon that the public sunshade umbrella is automatically folded when the wind power is low, the normal use of the sunshade umbrella is influenced, the mood of people is damaged is avoided, meanwhile, the device is prevented from being frequently folded and unfolded, and the service life of the device is prolonged.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
