Description

TECHNICAL FIELD

The sunshade can not only block the scorching summer sun, but also enable the intense sunlight to illuminate the indoor space in the form of diffuse light, making the indoor light bright and non-dazzling, and not affecting the user's view of the outdoor landscape from the indoor space, thus extending the living space from the indoor space to the outdoor space and creating new living space. The sunshade has special anti-ultraviolet function, which not only protects the human skin from ultraviolet radiation, but also greatly prolongs the service life of indoor decoration and furniture. With the development of society, people's living quality is gradually improving, and more and more families will go camping around the city during holidays by car. When parking and resting, in order to shield the sunlight and avoid the harm of ultraviolet rays to the human skin, people will install a sunshade on one side of the car, so that when people are parking and resting, they only need to open the sunshade on the side of the car to achieve the effect of sunshade and rain protection, and when people are ready to leave the car, they can fold up the sunshade.

The manual sunshade is small in size and light in weight, and is suitable for installation on a general family car. However, in the user's use process, the manual sunshade is relatively cumbersome when supporting and folding, and the user needs to slowly roll the cloth to achieve unfolding or folding, and needs to put the side edge of the cloth into the fixing slot on the supporting rod to improve the stability and wind resistance of the sunshade. When encountering special weather interference such as wind and rain, the cloth fluctuates under the action of external force, and it is difficult for one person to complete the opening or folding of the sunshade, which affects the user experience.
