The soundproof cover flip cover 3 is located on the side of the soundproof cover body 2 away from the pressure relief valve body 1 and is rotatably connected to the soundproof cover body 2. The soundproof cover flip cover 3 is provided with a first transmission mechanism 31, and the soundproof cover body 2 is connected with the first transmission mechanism 31. A second transmission mechanism 21 is provided at a position corresponding to the first transmission mechanism 31. The second transmission mechanism (21) is drivingly connected to the first transmission mechanism (31). The soundproof cover flip 3 passes through the first transmission mechanism 31 and the second transmission mechanism 21. The transmission fit can be rotated in a direction closer to the soundproof cover body 2 or in a direction away from the soundproof cover body 2 relative to the soundproof cover body 2 to adjust the opening area of the soundproof cover body 2, thereby realizing the connection between the pressure relief valve body 1 and the soundproof cover body 2. The ventilation area of the ventilation duct formed between the cover bodies 2 is adjustable to meet the needs of different pressure relief scenarios.

In specific implementation, as shown in FIG. 1 , the soundproof cover body 2 can be located on the pressure relief valve body 1 , the soundproof cover flip cover 3 is located above the soundproof cover body 2 , and the soundproof cover flip cover 3 can pass through the first transmission mechanism 31 and the second The cooperation of the transmission mechanism 21 rotates in the s1 direction shown in Figure 2 relative to the soundproof cover body 2, so that the covering area of the soundproof cover flip cover 3 for the soundproof cover body 2 is reduced, that is, the open area of the soundproof cover body 2 is increased, and then This increases the ventilation area of the ventilation duct formed between the pressure relief valve body 1 and the soundproof cover body 2 to achieve rapid and efficient pressure relief of the pressure relief valve device.

Alternatively, the soundproof cover flip 3 can rotate relative to the soundproof cover body 2 in the s2 direction shown in Figure 2 through the cooperation of the first transmission mechanism 31 and the second transmission mechanism 21, so that the soundproof cover flip cover 3 covers the soundproof cover body 2 Increase, that is, the open area of the soundproof cover body 2 is reduced, which in turn reduces the ventilation area of the ventilation duct formed between the pressure relief valve body 1 and the soundproof cover body 2, so as to ensure that the sound insulation effect of the soundproof cover is better. This can reduce the impact of noise, ensure a good ear pressure experience for people in the car when opening the door, and have excellent road noise performance, improving NVH (Noise, Vibration, Harshness) performance.

For example, when the door of the vehicle is in an open state, the soundproof cover flip cover 3 can be moved relative to the soundproof cover body 2 along the s1 direction shown in Figure 1 through the cooperation of the first transmission mechanism 31 and the second transmission mechanism 21. By rotating, the covering area of the soundproof cover flip cover 3 on the soundproof cover body 2 is reduced, that is, the open area of the soundproof cover body 2 is increased, and rapid and efficient pressure relief can be achieved. When the door of the vehicle is in a closed state, the soundproof cover flip cover 3 can be rotated in the s2 direction shown in Figure 1 relative to the soundproof cover body 2 through the cooperation of the first transmission mechanism 31 and the second transmission mechanism 21, so that the sound insulation can be achieved. The covering area of the soundproof cover body 2 by the cover flip cover 3 is increased.
