Self-adaptive automobile rear sunshade

Abstract

The invention discloses a self-adaptive automobile rear sunshade. The sunshade comprises a reel arranged in a frame, wherein a rear window is arranged in the reel, the reel is arranged at one side ofthe rear window, a shade cloth is wound on the reel, a first movable cavity and a second movable cavity are formed in the two sides of the rear window, the second movable cavity and the first movablecavity are formed in the frame, the two ends of the reel are fixedly connected with rotating shafts, one of the rotating shafts is rotationally connected with the interior of the first movable cavity,an upper baffle is fixedly connected under the rotating shaft, and a convex lens is arranged on the side, close to the rear window, of the interior of the first movable cavity. According to the sunshade, under the irradiation of sunlight, through the focusing effect of the convex lens, with the cooperation of the reaction of memory metal to temperature, the reel is separated from being bound andcan freely rotate; and under the action of gravity, the shade cloth wound on the reel can be naturally scattered, light rays can be shielded, and a user does not need to manually add the shade cloth.

Description

technical field [0001] The invention relates to the technical field of automobile auxiliary equipment, in particular to an adaptive automobile rear sunshade. Background technique [0002] The car sunshade can be divided into three types according to the position: front shield, side shield and rear shield. When the sun shines directly into the car and the temperature rises, the environment inside the car will become very poor.

Problems solved by technology

[0003] However, the sunshade needs to be put up artificially. No matter whether the sunshade is placed on the outer surface of the car or inside, it needs to be placed manually. Moreover, the sunshade placed on the outer surface is more troublesome to fix, and it is easy to be blown away by the wind. Due to the way of suspension, it is also difficult to fix. Although the sunshade protects the car, it is troublesome to use
