The invention discloses a ventilation hood cover assembly and an automobile front cover. The ventilation hood cover assembly comprises a fixed guide rail, a sliding block, a hood cover, a pivot shaftand a driving mechanism. The cover cap is located above the fixed guide rail, and the rear end of the cover cap is connected with the fixed guide rail through a pivot shaft; a guide frame which obliquely extends is arranged on the bottom surface of the cover cap; the sliding block is arranged on the fixed guide rail and is in sliding connection with the guide frame. And the output end of the driving mechanism is connected with the sliding block. According to the ventilation hood cover assembly and the automobile front cover, when an automobile is not started or runs at a low speed, the hood cover is in a closed state and keeps good sealing performance, and at the moment, the engine still sucks air from the front grille. Under the working conditions of high-speed running of an automobile and the like, the cover cap is automatically opened to increase air intake for the engine, a heat dissipation channel is provided for the engine compartment while power is improved, the temperature of the engine compartment can be greatly reduced, and rapid heat dissipation of the engine is facilitated.

    本发明公开了一种通气罩盖组件及汽车前盖,包括固定导轨、滑块、罩盖、枢转轴和驱动机构;所述罩盖位于所述固定导轨的上方,所述罩盖的后端与所述固定导轨通过枢转轴连接;所述罩盖的底面上设置有倾斜延伸的引导架;所述滑块位于所述固定导轨上,所述滑块与所述引导架滑动连接;所述驱动机构的输出端与所述滑块连接。本发明公开的通气罩盖组件及汽车前盖,在汽车未启动或者低速行驶时,罩盖处于关闭状态并保持良好的密封性能,此时发动机仍然从前格栅吸气。在汽车高速行驶等工况下,罩盖自动打开向发动机增加进气,在提高动力的同时还给发动机舱提供了散热的通道,可以大大降低发动机舱的温度,利于发动机快速散热。
