Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a side window shade curtain for a vehicle. Background Art

[0002] With the improvement of living standards, the number of cars has also increased significantly, and car-related problems have also emerged. For example, when driving in the summer, the car body is exposed to direct sunlight while driving or in an open-air parking lot, and the temperature inside the car will rise sharply. At present, the light-blocking devices used for car windows on the market mainly include plastic plates, colored reflective coatings, and sunscreen curtains. When using plastic plates, they need to be adsorbed on the car windows, which is cumbersome and not beautiful; colored reflective films have poor light-blocking effects and reduce the transparency of the car windows;

[0003] Therefore, sunscreen curtains came into being. Most of the existing sunscreen curtains are installed in a curtain-like manner, using slide rails for sliding installation or simple pre-tightened reels for installation. In the slide rail installation method, the free end of the sunscreen curtain is in a non-fixed state, and it will shake during vehicle driving, resulting in poor shading effect. Both ends of the reel installation are fixed, which solves the disadvantages of track installation to a certain extent. However, in order to ensure light transmittance, the thickness of the sunscreen curtain is generally thin or fine light-transmitting holes are provided on the surface, which causes curling at the edge of the sunscreen curtain, affecting the appearance, and wrinkles will appear when the reel shrinks, resulting in loose storage and winding, and poor surface flatness after being unfolded again. Moreover, when the car window is open and the roller curtain is not retracted, the edge of the roller curtain is affected by the gas, resulting in high-frequency vibration and loud noise. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a vehicle side window sunshade curtain, which is installed by a pre-tightened reel to initially provide a pre-tightening force for the curtain body to ensure the flatness of the middle position of the curtain body, and at the same time, a traction line is added to the edge position, and the traction line is tightened by a winding roller with a pre-tightening function, so that the edge position of the curtain body is flattened by the internal pre-tightening force of the traction line, thereby ensuring the overall flatness of the curtain body and improving the aesthetics and durability of the curtain body. At the same time, when the car window is opened, the edge position of the curtain body is straightened by the traction line, which can effectively reduce the high-frequency vibration of the edge position caused by the influence of airflow and reduce the noise generated, which can effectively solve the problems in the background technology.
