The invention discloses a ventilation device facilitating air flow inside and outside a vehicle. The ventilation device comprises an mounting frame and a plurality of valve plates. The mounting framecomprises a main frame body and secondary frame bodies. Each secondary frame body comprises a frame, a ventilation opening and a clamping piece. The clamping piece comprises a connecting plate and a holding plate. The arrangement direction of the two holding plates is perpendicular to the arrangement direction of the multiple secondary frame bodies, and the cross section of the two holding platesin the direction perpendicular to the arrangement direction of the multiple secondary frame bodies is of a wedge-shaped structure. The valve plates are made of flexible materials, are adopted to coverthe ventilation openings and comprise at least one socket groove. Each valve plate is located between the two holding plates and the corresponding ventilation opening at the same time. According to the ventilation device, after the air pressure inside and outside the vehicle is balanced, the ventilation device can quickly return to the original state, and the valve plate can cover and press the ventilation opening more tightly under the action of the holding plate when the ventilation device is in the static state, so that the noise outside the vehicle can be reduced as much as possible, andthe vehicle use experience of a user is improved.

    一种利于车内外气体流动的通风装置,其包括安装架,以及多个阀片。所述安装架包括主框体,以及次框体。每一个次框体包括框架,通风口,以及卡接件。所述卡接件包括连接板,以及保持板。两个所述保持板的排列方向垂直于多个所述次框体的排列方向且在沿垂直于多个所述次框体的排列方向的截面上为楔形结构。所述阀片由柔性材料制成并盖设在所述通风口上并包括至少一个插口槽。所述阀片同时位于两个所述保持板与通风口之间。本通风装置不仅使得在车内外的气压平衡后,可以快速回复到原始状态,而且在其静止状态时由于所述保持板的作用,使得所述阀片可以更紧密地盖压在所述通风口上,这样都可以尽可能地降低来自车外的噪音,提高用户的用车体验。
