[0002] With the continuous development of automobile technology, car sunroofs have become standard for many models, which bring more natural light into the car and increase the sense of transparency of the space. However, while car sunroofs bring convenience, they also bring some problems, such as excessive sunlight, damage from ultraviolet rays, and heat accumulation. In order to solve these problems, car sunshades came into being and became the ideal companion of sunroofs.

[0003] First, the sunshade can effectively block direct sunlight. When the sunlight is too strong, we can pull down the sunshade to prevent the sunlight from directly shining into the car and protect the people in the car from being burned by the sun. At the same time, the sunshade can also prevent the temperature in the car from being too high and maintain the comfort in the car. Secondly, the sunshade can prevent the damage of ultraviolet rays. Long-term ultraviolet rays can cause damage to human skin and may even cause skin cancer. The use of sunshades can effectively block most of the ultraviolet rays and protect the health of people in the car. In addition, the sunshade can effectively protect the privacy in the car, reduce the risk of peeping and theft, and bring a safer driving and parking experience to the car owner. The existing sunshade curtains usually use two or more steel wires for the traction operation of opening and closing. When installing two or more steel wires, the two ends of the sunshade need to be connected to the sunshade, which makes the sunshade structure more complicated and difficult to repair when the steel wire is damaged, which is not convenient for product promotion and use. Utility Model Content
