Installation structure of dual-channel air quality detection module

Abstract

The invention discloses an installation structure of a dual-channel air quality detection module. The installation structure comprises the dual-channel air quality detection module, a heating ventilation and air conditioning assembly and an interior trimming board, wherein the dual-channel air quality detection module comprises a module main body, a vehicle external channel intake / exhaust interface communicated with a vehicle external channel of the module main body as well as a vehicle internal channel intake / exhaust interface communicated with a vehicle internal channel. The module main bodyis fixedly arranged on an air handling unit housing of the heating ventilation and air conditioning assembly; the vehicle internal channel intake / exhaust interface is fixedly formed in the interior trimming board; the vehicle external channel intake / exhaust interface is formed in an air conditioning fresh air inlet. According to the installation structure disclosed by the invention, the detectionmodule is integrated on the heating ventilation and air conditioning assembly and is convenient to assemble, so that the cost is reduced; moreover, the air conditioning fresh air inlet and atmospheric environment outside a vehicle are always kept in communication to serve as an introduction channel of pollution gas outside the vehicle; PM2.5 data outside the vehicle can be accurately measured, and the problems of increased manufacturing cost and difficult assembly caused by punching of a vehicle body and installation of the vehicle external intake / exhaust interface can be solved.

Description

technical field [0001] The invention relates to the field of automobile air conditioners, in particular to the 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 gradually being used in the car. The installation structure of the common dual-channel PM2.5 detection module on the car is relatively complicated, and the main part often needs to be designed with auxiliary mounting brackets to be fixed on the vehicle body. And in the design of the passage outside the vehicle, because it is necessary to introduce the polluted gas outside the vehicle into the module for detection, if it is directly discharged into the vehicle after detection, there will be secondary pollution, so it is necessary to design the discharge passage outside the vehicle, and the introduction and discharge of...
