Because in actual work, in order to make air conditioner control panel convenient to detach, can let air conditioner control panel pass through the trip structural mounting and in the driver's cabin usually to easy dismouting when repairing. However, if the hook is designed to be large, the difficulty of detachment is increased. Therefore, in order to facilitate the detachment, the hook is usually designed to be smaller, which reduces the strength of the hook itself, so that the hook is easily damaged during the detachment, thereby affecting the re-installation.

However, in this embodiment, the connecting member 700 does not need to be detached from the rear cover 200 when being detached, so the bottom air hook structure connecting the connecting member 700 and the rear cover 200 can be designed to be larger, which can improve the hook strength and make it not easy to be damaged, and meanwhile, the side of the locking groove 710 far away from the rear cover 200 is set to be an inclined surface, which reduces the difficulty of detachment.

The working principle of the utility model is as follows:

the utility model provides a good vehicle air conditioner control panel of homogeneity in a poor light, through utilizing light guide 524 to transmit the light that backlight 310 sent to printing opacity district 501, and light guide 524, printing opacity district 501, backlight 310 one-to-one for a backlight 310 just can satisfy the intensity demand of a printing opacity district 501, has reduced the quantity of backlight 310, and the cost is reduced has reduced installation space. And the lights emitted by the backlight lamps 310 do not affect each other, so that the backlight of the light-transmitting area 501 can be consistent only by keeping the illumination intensity of a single backlight lamp 310 consistent with the light transmittance of a single light-guiding member 524, thereby improving the uniformity of the backlight.
