An automobile cab pressure relief valve assembly and an automobile

Abstract

The invention provides an automobile cab pressure relief valve and an automobile. The pressure relief valve comprises a pressure relief valve body, wherein the pressure relief valve body consists of a cavity structure and a top mechanism arranged surrounding the same; a first end opening of the cavity structure consists of a first opening part and a second opening part, the top mechanism consists of a fixed grating structure and a movable grating structure, the fixed grating structure fixedly covers the first opening part, the movable grating structure is movably connected with a first side of the fixed grating structure, the movable grating structure rotates relative to the fixed grating structure and has a closed state completely covering the second opening part and an opening state enabling the second opening part to be exposed; the automobile cab pressure relief valve further comprises a pressure relief rubber sheet, the rubber sheet is arranged inside the cavity structure and completely covers the first end opening; the first end of the pressure relief rubber sheet is connected with one side end of the first end opening of the cavity structure, and when being in the closed state, the movable grating structure compresses the pressure relief rubber sheet and the movable grating structure and the cavity structure are fixedly arranged in a clamping manner.

Description

technical field [0001] The invention relates to the technical field of automobile parts manufacturing, in particular to an automobile cab pressure relief valve assembly and an automobile. Background technique [0002] The cab of a modern car is usually a relatively sealed space, but in a completely sealed space, the door cannot be opened or closed due to the air pressure when the door is opened and piped, and the occupants will also feel uncomfortable due to the large change in ear pressure. The cab cannot be a completely sealed space. However, if the sealing of the cab is too poor, the noise in the cab will be too large, the ride comfort will be poor, and it will be easy to get water when it rains or when the car is washed, causing the parts in the car to be damaged by water immersion. Therefore, under the premise of avoiding water ingress and reducing the noise inside the car as much as possible, the problem of drastic changes in cab air pressure caused by opening and clo...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an automobile cab pressure relief valve assembly and automobile, which solves the problem that some structures in the traditional pressure relief structure are too simple to meet the pressure relief requirements or some structures are too complicated and the assembly cost is high. It solves the problem of the rapid change of the air pressure in the cab caused by opening and closing the door to the greatest extent, making it easy to open and close the door, and the structure is simple and the cost is reduced
