Problems solved by technology

However, the space in the cabin of a car is limited, and the first three methods required an increase in the corresponding space in the cabin to be implemented. Therefore, the first three methods will not be used in practical applications. The fourth method can only be used for high-frequency components in the noise, and the fifth method The cost of this method is huge, so the latter two methods will not be used in practical applications
Therefore, the resistive muffler installed on the exhaust system is mostly used at present, but the resistive muffler is to add sound-absorbing materials in the pipeline, the installation is complicated, time-consuming, laborious, costly, and can only solve high-frequency noise

Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] Such as figure 1 , figure 2 As shown, a thin-film shock absorber installed on the air intake system of an automobile is used to eliminate at least one kind of noise inside the vehicle caused by the air intake system. The air intake system of the automobile includes an air intake pipe 1 and an air filter 2 connected in sequence And the air outlet pipe 3, the vibration absorber includes an opening 5 opened at the abnormal vibration place of the intake pipe 1 (ie, the place with the largest vibration) and a film 6 sealingly covering the outside of the opening 5, and the aperture of the openin...

Abstract

The invention discloses a film vibration absorber installed on an air inlet system of an automobile. The film vibration absorber is used for eliminating at least one kind of interior noise caused by the air inlet system. The air inlet system of the automobile comprises an air inlet pipe, an air filter and an air outlet pipe which are sequentially connected. The vibration absorber comprises an opening hole formed in the portion, which vibrates abnormally, of the air inlet pipe, and a film covering the outer side of the opening hole in a sealing mode. The hole diameter of the opening hole is smaller than the diameter of the air inlet pipe. On the premise of not increasing a noise lowering space of the air inlet system and under the reasonable cost control, the noise of low, medium and high frequency bands in the air inlet system can be effectively lowered.

Description

technical field [0001] The invention relates to a vibration-absorbing device for an automobile air intake system, in particular to a film vibration absorber installed on the automobile air intake system. Background technique [0002] As people's requirements for the comfort of automobiles are getting higher and higher, the field of vibration and noise of complete vehicles has been paid more and more attention by OEMs. To reduce the noise in the cab, engineers must control and adjust each noise source of the vehicle to ensure that the noise level and frequency components will not have a negative impact on the passengers in the vehicle. The intake noise, as one of the important noise sources of the vehicle, must be considered in the process of vehicle design. At present, there are two solutions to solve the intake noise of automobiles, one is to add a resistive muffler, and the other is to add a resistive muffler. The resistant muffler has the following methods: 1. Increase ...
