The invention provides a side air curtain and an automobile. The side air curtain comprises an air curtain body provided with an air duct and a first baffle that can open and close an inlet in the windward side of the air duct. When the vehicle speed is smaller than a preset speed value, the first baffle closes the inlet; and when the vehicle speed reaches a preset speed value, the first baffle opens the inlet. When the vehicle speed is smaller than the preset speed value, namely, in a static state and a low-speed state, the first baffle closes the inlet in the windward side of the air duct, namely, the inlet is totally closed; and the first baffle can keep continuity with modeling faces on the two sides of an automobile front bumper. When the vehicle speed reaches a preset speed value, that is to say, during high-speed driving, the first baffle opens the inlet, so that an airflow at the front bumper enters the air duct of the air curtain body from the inlet and is guided to the two sides of the front wheel through the air duct, and thus separation of the airflow on the two sides of the automobile body is avoided, and the effect of reducing the air resistance of the whole automobile is achieved. Therefore, the air resistance is effectively reduced when the automobile runs at a high speed; meanwhile, continuity of modeling faces on the two sides of the automobile front bumper instatic and low-speed states is guaranteed.

    本发明提供一种侧气帘和汽车,侧气帘包括设置有风道的气帘本体;能够开闭风道迎风侧的入口的第一挡板,当车辆速度小于预设速度值时,第一挡板关闭入口;当车辆速度达到预设速度值时,第一挡板打开入口。当车辆速度小于预设速度值时,即静止及低速状态下,第一挡板关闭风道迎风侧的入口,即入口全封闭,该第一挡板能够与汽车前保两侧造型面保持连续性;当车辆速度达到预设速度值时,即高速行驶时,第一挡板打开入口,从而使前保处的气流,由入口进入气帘本体的风道,经由风道引导至前轮两侧,避免了气流在车身两侧的分离,达到降低整车风阻的效果,故实现了在汽车高速行驶时有效降风阻,同时保证了静止及低速状态下汽车前保两侧造型面的连续性。
