Embodiment Construction
[0019] Below, in conjunction with the accompanying drawings and specific embodiments, the air volume adjustment button durability test device of the automobile air-conditioning system of the present invention will be further described in detail;
[0020] According to the durability test requirements of the air conditioner controller, the durability test of the air volume adjustment button is performed in accordance with the following steps (1) and (2) for each cycle, and a total of 8000 cycles are performed.
[0021] (1) Turn on the power, press the button above the air volume control button, each time the air volume increase button is pressed, the wind speed of the display screen will increase by 1, and the blower wind speed will increase. Operate the air volume increase button 6 times, and the maximum air volume display will be 7 gears.
[0022] (2) Press the button below the air volume control key, and each time you press the air volume down key, the wind speed on the displa...
