What is the sun shield called in a car?

The component in a car used to block sunlight is commonly called a "sun visor" or "automobile sun shield" in English. Its core function is to be installed above the heads of the driver and front-seat passengers, blocking direct sunlight through an adjustable flip structure to enhance driving safety and comfort. According to the industry standard QC/T 629-2021, sun visors must meet technical requirements such as high temperature resistance, UV resistance, and moderate operating torque (0.4N·m to 4N·m). They are typically made of ABS plastic or covered with a flexible surface, while some high-end models feature fabric designs matching the original car interior or magnetic attachments (such as those designed for German cars). When purchasing, It is best to prioritize vehicle-specific models to ensure proper fit and smooth operation.
