The cover plate 12 comprises a first portion 121 and a second portion 122 located below the first portion 121, which are connected to each other, i.e. the first portion 121 and the second portion 122 are arranged in the up-down direction, and the second portion 122 can be used for connecting with the table body. The screen assembly further comprises a shielding glass plate 15 arranged between the segment code screen 14 and the touch screen 13; the light guide sheet 17 is adhered to the back surface (namely the surface close to the circuit board 18) of the segment code screen 14, the shielding glass plate 15 and the front surface of the segment code screen 14 are completely attached through an optical adhesive layer to form a display component, namely the light guide sheet 17, the segment code screen 14 and the shielding glass plate 15 form the display component; the touch screen 13 and the first portion 121 are fully attached to each other through an optical adhesive layer to form a touch component, that is, the cover plate 12 and the touch screen 13 form a touch component. The control knob assembly 30 is convexly disposed on the second portion 122, in fact, a fixed portion of the control knob assembly 30 is connected to the circuit board 18, a rotating portion is rotatably connected to the fixed portion to sense different signals when the control knob assembly 30 rotates, knob assembly holes for the control knob assembly 30 to pass through are disposed on the light guide cover 11 and the cover plate 12 (specifically, the second portion 122), and at least a portion of the control knob assembly 30 extends out of the second portion 122, so as to facilitate the operation of the driver and the passenger. The light guide sheet 17 may be adhered to the segment code screen 14 by a double-sided tape, for example, the double-sided tape is disposed around the edge of the back of the segment code screen 14 for adhering to the light guide sheet 17.

When the touch screen 13 and the segment code screen 14 are simultaneously arranged, considering that the segment code screen 14 and the touch screen 13 are easy to cause signal interference, in order to solve the problem, the distance between the touch screen 13 and the segment code screen 14 can be increased, so that the thickness of the whole touch display panel 10 is increased, the occupied space of a central console is increased, more seriously, in order to avoid the mutual interference of the touch screen 13 and the segment code screen 14, the distance between the touch screen 13 and the segment code screen 14 is set to be larger, so that the display effect of an automobile air conditioner control device can be influenced, particularly, a driver who is driving is poor in display effect, the attention of the driver is influenced, and traffic accidents can be caused. In the invention, the shielding glass plate 15 is additionally arranged between the segment code screen 14 and the touch screen 13, so that the shielding effect of the shielding glass plate 15 is realized, the distance between the touch screen 13 and the segment code screen 14 can be reduced, the mutual interference of signals of the touch screen 13 and the segment code screen 14 can be avoided when the distance between the touch screen 13 and the segment code screen 14 (namely the size of the touch screen 13 and the segment code screen 14 in the thickness direction) is smaller, the accuracy of display and touch signals is improved, and the distance between the touch screen 13 and the segment code screen 14 is reduced, so that the display effect of the whole automobile air conditioner control device can be improved. Although the shielding glass plate 15 is added, the glass has good light transmission, so that the light transmission is basically not influenced, and the display effect of the automobile air conditioner control device can be improved; and glass has certain intensity and heat resistance, so its shaping back non-deformable, and even if heat slightly also can not take place to warp to guarantee the normal transmission of light, further improve vehicle air conditioner controlling means's display effect. Furthermore, the shielding glass plate 15 and the segment code screen 14 are fully attached, so that the loss of light rays can be further reduced, and the display effect of the air conditioner control device can be better improved.

In one embodiment of the invention, the touch screen 13 and the shielding glass plate 15 are arranged at intervals, namely, a gap is reserved between the touch screen 13 and the shielding glass plate 15 in the thickness direction of the automobile air conditioner control device, and by adopting the mode, on one hand, a large number of optical adhesive layers are not needed between the touch screen 13 and the shielding glass plate 15, so that the manufacturing cost of the automobile air conditioner control device can be reduced; on the other hand, since the shielding glass plate 15 is provided in the present invention, the distance between the touch screen 13 and the shielding glass plate 15 does not need to be set too large, i.e., can be set very small, so that the display effect of the vehicle air conditioner control device is not substantially affected even though the vehicle air conditioner control device is provided with the above-mentioned gap.

Furthermore, considering that dust easily enters a gap between the touch screen 13 and the shielding glass plate 15 after the touch screen 13 and the shielding glass plate 15 are arranged at intervals, and further transmission of light is influenced, the sealing foam is additionally arranged between the touch screen 13 and the shielding glass plate 15, so that impurities such as dust can be prevented from entering the gap between the touch screen 13 and the shielding glass plate 15 to influence the transmission of light, damage possibly caused by hard connection between the touch screen 13 and the shielding glass plate 15 can be prevented, and the yield of the automobile air conditioner control device is improved. Preferably, the sealing foam is attached to the peripheral edge between the shielding glass plate 15 and the touch screen 13 by a double-sided tape, that is, the sealing foam is located between two opposite surfaces of the touch screen 13 and the shielding glass plate 15 and is arranged around the edge of the two. In the embodiment where the touch screen 13 and the shielding glass plate 15 are disposed at an interval, the touch screen 13 and the shielding glass plate 15 may also be separated by other structural members such as a sealant and a sealing gasket. The light guide cover 11 and the touch screen can be separated by arranging a stepped structure on the light guide cover, if the installation cavity for installing the screen assembly can be arranged to be the stepped structure, the touch screen 13 is installed on the stepped surface, and the distance between the touch screen 13 and the shielding glass plate 15 is controlled by the height of the stepped surface from the bottom surface of the installation cavity (detailed below).

Further, the shielding glass plate 15 and the segment code screen 14 are fully attached through an optical adhesive layer; touch screen 13 passes through the optical cement layer with apron 12 and laminates completely, so, can reduce laminating material to the influence of light as far as possible, further increase whole vehicle air conditioner controlling means's display effect.

Preferably, the distance between the shielding glass plate 15 and the touch screen 13 (i.e., the size of the shielding glass plate 15 and the touch screen 13 in the thickness direction) is 0.3-0.7 mm, such as 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, and the like, and the distance can not only further prevent the electric signal of the segment code screen 14 from affecting the touch screen 13, but also reduce the loss of the gap between the shielding glass plate 15 and the touch screen 13 to light as much as possible, thereby better improving the display effect of the automotive air conditioning control device. It is understood that the distance between the shielding glass plate 15 and the touch screen 13 may also be other values, such as 0.25mm, 0.75mm, 0.8mm, etc.

In a preferred embodiment of the present invention, in an embodiment where the distance between the shielding glass plate 15 and the touch screen 13 is 0.3 to 0.7mm, the sealing foam 19 with a thickness of 0.9 to 1.1mm, such as 0.9mm, 1.0mm, 1.1mm, may be selected, and when the shielding glass plate 15 and the touch screen 13 are adhered and pressed, the sealing foam 19 deforms, so that a gap with a thickness of 0.3 to 0.7mm is formed between the shielding glass plate 15 and the touch screen 13.

As described above, if the strength of the shielding glass plate 15 is too small, bending is easily caused, and thus, light is lost, thereby affecting the display effect of the vehicle air conditioner control device. In order to avoid the above problem, the thickness of the shielding glass plate 15 is preferably 1.9 to 2.1mm, such as 1.9mm, 2.0mm, or 2.1 mm.

The backlight source may be an LED light source, which may be provided in a plurality of numbers, and may specifically be disposed corresponding to the light guide hole 113.

In order to realize the color display effect, a color segment code screen can be selected, preferably, the light guide sheet 17 is a color film and has a plurality of color transparent areas, the color transparent areas are correspondingly arranged with a plurality of controllable transparent areas on the segment code screen 14, namely, the color transparent areas corresponding to each controllable transparent area on the light guide sheet 17 are constructed to have preset colors, so that light emitted by the backlight source irradiates on the color transparent areas through the light guide hole 113, and color display can be realized when the light of the transparent color transparent areas irradiates on the corresponding display areas on the segment code screen.
