Abstract

The invention provides an installation structure for an air filter air inlet pipe and a resonant cavity. The installation structure is simple, is convenient to install and fully utilizes space, so that the resonant cavity is connected and fixed in a limited space. The installation structure comprises the air filter air inlet pipe and the resonant cavity, so that the air filter air inlet pipe is provided with an interface branch pipe communicated with the air inlet pipe, a first fixing bracket fixedly connected with a left longitudinal beam assembly, and a second positioning bracket matched with a first positioning bracket; and the resonant cavity is provided with an air inlet matched with the interface branch pipe, a fixing bracket fixedly connected with the left longitudinal beam assembly, and the first positioning bracket connected with the air filter air inlet pipe. A plurality of positioning brackets and fixing brackets are arranged, so that the air filter air inlet pipe and the resonant cavity can be fixedly connected into a whole and can be fixed on the left longitudinal beam assembly to meet the requirement of a modern engine air inlet system.

Description

technical field [0001] The invention belongs to the technical field of automobile intake systems, and in particular relates to an installation structure of an air filter intake pipe and a resonant cavity used in the automobile intake system. Background technique [0002] As a means of transportation, automobiles play a very important role in modern industrial society. With the development of society, people have higher and higher requirements for the comfort and environmental protection of automobiles, one of which is the requirement for noise. The noise of the air intake system is one of the most important noise sources of the car. The noise mainly refers to the noise at the air intake. This noise source is very close to the cabin, so it contributes a lot to the noise inside the car. Mouth noise is also the most important source of pass-by noise in automobiles. In order to reduce the influence of air intake noise on interior noise and pass-by noise, in addition to ration...
