An installation structure of a dual-channel air quality detection module

Abstract

An installation structure of a dual-channel air quality detection module, including a dual-channel air quality detection module, an HVAC assembly, and an interior trim panel. The air intake and exhaust ports of the outer channel, and the air intake port of the inner channel connected with the inner channel. The main body of the module is fixed on the air-conditioning box shell of the HVAC assembly, the air intake interface of the interior passage is fixed on the interior trim panel, and the air intake and exhaust interface of the exterior passage is arranged at the fresh air intake of the air conditioner. The invention integrates the detection module on the HVAC assembly, which is convenient for assembly and saves costs. At the same time, the fresh air inlet of the air conditioner is kept in constant communication with the atmospheric environment outside the vehicle as the introduction channel of the polluted gas outside the vehicle to accurately measure the PM2 outside the vehicle. .5 data, and can avoid the problem of increased manufacturing cost and difficult assembly caused by opening holes in the body to install the intake and exhaust ports outside the vehicle.

Description

technical field [0001] The invention relates to the field of automobile air conditioners, in particular to an installation structure of an air quality detection module. Background technique [0002] The air quality detection module, especially the dual-channel PM2.5 detection module, can simultaneously collect the gas quality inside and outside the car, and is now gradually being used in the car. The installation structure of the common dual-channel PM2.5 detection module on the car is relatively complex, and the main part often needs to design auxiliary mounting brackets to be fixed to the body. And in the design of the outside channel, because it is necessary to introduce the polluting gas outside the car into the module for detection, if it is directly discharged into the car after detection, there will be secondary pollution, so it is necessary to design the outside exhaust channel to introduce and discharge the outside gas. design is particularly important.
