Abstract
A ventilation device for air flowing inside and outside a vehicle includes a mounting frame and a plurality of valve plates. The mounting frame includes a primary frame and a plurality of secondary frame bodies. Each of the secondary frames includes a frame, a vent, and a clamping part. Each of the clamping parts includes a connecting plate and a retaining plate. Each of the valve plate covers the vent and comprises at least one socket slot. The valve plates are located between the two retaining plates and the vent. The ventilation device can not only rapidly return to an original state after the air pressure inside and outside the vehicle is balanced, but can also reduce noise from outside the vehicle as much as possible, and improve the vehicle usage experience of a user.
