The invention provides an air inlet grille and an automobile. The air inlet grille comprises a grille frame, a reset mechanism and a baffle. The grating frame comprises a top plate, a bottom plate, a first side plate and a second side plate. The baffle is located between the top plate and the bottom plate and rotationally connected with the first side plate and the second side plate. One end of the reset mechanism is connected with the baffle, the other end of the reset mechanism is connected with the grating frame, the rotatable baffle is arranged in the grating frame, and the reset mechanism and the bottom plate are combined to limit the rotation stroke of the baffle, so that a preset angle is formed between the baffle and the bottom plate in a static state; along with the increase of the vehicle speed, the baffle rotates slowly under the action of the airflow pressure difference and the reset mechanism till making contact with the bottom plate, part of the air inlet is closed through the baffle, and therefore the air inlet amount is reduced. According to the air inlet grille, the change that the air inlet is reduced along with the increase of the vehicle speed is achieved through the design of a mechanical structure, the heat dissipation requirement is met, meanwhile, wind resistance is reduced, additional motor and power source driving is not needed, and cost is reduced.

    本申请提供了一种进气格栅和汽车,该进气格栅格包括格栅框架、复位机构和挡板;格栅框架包括顶板、底板、第一侧板和第二侧板挡板位于顶板与底板之间,且与第一侧板和第二侧板转动连接;复位机构的一端与挡板连接,另一端与格栅框架连接,通过在格栅框架内设置可转动的挡板,并结合复位机构和底板对挡板的转动行程进行限制,使得挡板在静止状态下与底板呈预设角度;随着车速的增加,挡板在气流压差和复位机构的作用下慢慢发生转动直至与底板接触,利用挡板封闭部分进风口,从而减小了进风量;该进气格栅利用机械结构的设计实现了进气口随车速的增大而减小的变化,解决散热需求的同时也减小了风阻,且不需要额外的电机和电源驱动,降低了成本。
