Automobile sound absorption door and installation method thereof

Abstract

The invention discloses an automobile sound absorption door and an installation method thereof, and relates to the technical field of automobile sound insulation and noise reduction. The automobile sound absorption door comprises an automobile door inner metal plate having the inner surface provided with an adhesive contour line, a door protection plate fixedly installed on the inner surface of the automobile door inner metal plate, and having the face, facing the automobile door inner metal plate, provided with a plurality of clamping hooks, a waterproof film adhered to the automobile door inner metal plate along the adhesive contour line, and sound absorption cotton arranged between the waterproof film and the door protection plate; and all the clamping hooks penetrate through the sound absorption cotton to be hung and fixed. The sound absorption door further comprises strip-shaped sealing foam, and the sealing foam is arranged in a surrounding mode in the circumferential direction of the door protection plate and clamped between the door protection plate and the automobile door inner metal plate. The invention further discloses an installation method based on the automobile sound absorption door. According to the automobile sound absorption door and the installation method thereof, the noise control effect is good, the noise level in a cab is effectively reduced, and the comfort degree of passengers is improved.

Description

technical field [0001] The present application relates to the technical field of automobile sound insulation and noise reduction, in particular to an automobile sound-absorbing door and an installation method thereof. Background technique [0002] At present, the noise level in the car is an important indicator of user comfort. As an important part of the cockpit, the door guard needs to absorb external wind noise and noise generated by moving parts such as window regulators. More and more car manufacturers are trying to reduce the noise inside the vehicle cabin to provide consumers with a more comfortable experience. [0003] In related technologies, the main technical solution for the sound insulation and noise reduction of the door guard is to fix the door guard on the door sheet metal, and the door sheet metal has a waterproof film, which plays a waterproof and sound-proof effect. [0004] However, the above-mentioned technical solution has the following defects. The re...

Problems solved by technology

[0004] However, the above-mentioned technical solution has the following defects. The reduction of noise is divided into sound insulation and sound absorption. There is only one layer of waterproof film between the door guard and the door sheet metal. The door sheet metal and the waterproof film can play a certain sound insulation effect, but Due to functional restrictions, holes need to be opened on the waterproof membrane, and the noise control effect is poor
