Description

Technical Field

[0001] The utility model relates to the technical field of automobile air conditioners, and in particular to a fixing structure of an electric component of an automobile air conditioner. Background Art

[0002] The car air conditioner is equipped with electrical components with auxiliary detection functions, such as PM2.5 sensors, negative ion sensors, indoor temperature sensors, AQS sensors, sunlight sensors, etc. These electrical components do not need to move or be subjected to force, and do not require too much power during use. In order to fix these electrical components, generally according to the size of the electrical components, large ones generally reserve 3 to 4 screw holes, medium ones reserve 2 screw holes, and small ones generally reserve one screw hole, so these electrical components are basically fixed with at least 1 to 4 screws, which invisibly increases the cost of screws; at the same time, it also increases the assembly cost and processing hours on the production line. Although this fixing method is relatively firm, it invisibly increases the cost and weight of the product; even in order to reduce costs, it also needs to be fixed with 2 screws, and the other 1 to 2 are fixed with positioning points or other methods, but it still needs to be fixed with screws in the end; the electrical component is fixed on the shell. If the electrical component fails during use, it is necessary to remove the fixing screws first before the electrical component can be unscrewed and replaced. If the space in the car is relatively small, it is difficult for the screwdriver to enter, and the disassembly and assembly of the electrical component is difficult.

[0003] After searching, the applicant found that the Chinese patent document with publication number CN214501645U disclosed a sensor fixing device and an air conditioner on October 26, 2021, and the sensor fixing device includes: a pipe fixing part, the pipe fixing part is provided with an opening adjustment area; a sensor mounting part, the sensor mounting part is connected to the outer side surface of the pipe fixing part; an adjustment component, the adjustment component is arranged in the opening adjustment area; wherein, the adjustment component is used to adjust the opening size of the opening adjustment area.
