[0021] A protective cover 8 is installed on the outside of the sleeve 1. The top of the protective cover 8 is higher than the fixing ring 5. The transparent cover 7 is fixedly installed on the top of the protective cover 8. The transparent cover 7 is made of transparent plastic material and can be folded at will. The transparent cover 7 can be stuffed into the protective cover 8 for storage.

[0022] There are multiple protective covers 8 in a circular array, the bottom of the protective cover 8 is hinged to the sleeve 1, and a transmission arm 9 is hinged to the inner top of the protective cover 8. The hinge point between the transmission arm 9 and the protective cover 8 is located in the middle position of the inner top of the protective cover 8. The end of the transmission arm 9 away from the protective cover 8 is hinged to the slider 3, and the hinge point between the transmission arm 9 and the slider 3 is located at the end of the slider 3 close to the sleeve 1. The slider 3 slides to the side away from the sleeve 1 to drive the transmission arm 9 to rotate, thereby driving the protective cover 8 to expand outward.

[0023] An elastic band 10 is provided at the position where the transparent cover 7 is connected to the protective cover 8. The maximum diameter of the protective cover 8 when unfolded is adapted to the tightness of the transparent cover 7. After the protective cover 8 is unfolded, the elastic band 10 at the bottom of the transparent cover 7 is stretched and the bottom of the transparent cover 7 is unfolded.

[0024] An extendable rain cover is fixedly connected between adjacent protective covers 8, and the top of the rain cover is fixedly connected to the elastic band 10. The shape of the rain cover after unfolding is the same as the shape between two adjacent protective covers 8 after unfolding, and the rain cover and the protective cover 8, the protective cover 8 and the transparent cover 7, and the transparent cover 7 and the rain cover are all in a sealed state.

[0025] A notch 11 is provided on one side of the top of the transparent cover 7 , and the notch 11 is oval in shape. The notch 11 is used to pass the connecting shaft of the car charging port cover, and soft magnetic strips 12 are fixedly installed in sequence along the top of the transparent cover 7 and the shape of the notch 11 .
