A blind hole 11 is provided on the second surface of the cover plate 1, and a button surface treatment layer is provided on the first surface of the cover plate 1. The button surface treatment layer includes a button pattern 12 and a light shielding layer 13 and a light transmitting layer 14. The button pattern 12 is a hollow pattern located on the light shielding layer 13, and the light transmitting layer 14 covers the button pattern 12; a touch pattern 31 is provided on the first surface of the touch glass 3, and the first surface of the cover plate 1 is bonded to the first surface of the touch glass 3 through the bonding adhesive layer 2. The second surface of the touch glass 3 is connected to the liquid crystal display screen 4, and the FPC5 is bound to the first surface of the touch glass 3.

[0025] In this embodiment, the button pattern 12 hollowed out in the light shielding layer 13 of the vehicle air conditioning and volume adjustment touch knob button cover 1 is displayed on the second surface of the cover 1 through the light transmitting layer 14. The user touches the blind hole 11 of the cover 1 through the button pattern 12 to adjust the air conditioning and volume functions, and displays the current control status and volume or the temperature set for the vehicle air conditioning on the LCD screen 4.

[0026] In this embodiment, the bonding adhesive layer 2 is an OCR adhesive layer with a thickness of 0.15-0.3, which is fully bonded to the cover plate 1 and the touch glass 3. In another embodiment, an OCA adhesive layer is used.

[0027] In this embodiment, the LCD display screen 4 is a TN screen or a TFT screen. In actual applications, the economical solution uses a TN screen, and the high-end solution uses a TFT screen. The LCD screen is mainly used to display the current control status and volume or the temperature set by the vehicle air conditioner.

[0028] See also Figure 1 , Figure 3 In the second embodiment, the shading layer 13 uses two layers of ink layers for shading. The first surface of the cover plate 1 is sequentially screen-printed with a first shading ink layer 131 and a second shading ink layer 132. A key pattern is hollowed out on the double-layer shading ink layers 131 and 132. A semi-transparent ink layer 141 and a diffusion ink layer are sequentially screen-printed on the key pattern to form a semi-transparent structure. In this way, the double-layer shading and semi-transparent structure can make the display effect of the transparent part and the shading part of the knob button better, and the display of the key pattern 12 is more obvious.

[0029] It is understandable that, in other embodiments, the light shielding layer 13 and the light transmissive layer 14 may adopt other materials, processes and structures of the prior art or a combination of the prior art.

[0030] See also Figure 1 , Figure 4 In the third embodiment, the cover plate 1 of the vehicle air conditioning and volume adjustment touch knob button is a tempered glass with a thickness of 0.7 to 3.0 mm, which is made by machining. There are three blind holes 11 on the second surface of the cover plate 1, and the blind holes are processed by etching or machining. The first blind hole 111 and the second blind hole 112 are located on both sides of the liquid crystal display screen, corresponding to the vehicle air conditioning button and the volume button, with a depth of 0.2 to 0.5 mm. The third blind hole 113 is a circular blind hole with a width of 10 to 15 mm and a depth of 0.2 to 0.5 mm, which is located in the center of the second surface of the cover plate 1, corresponding to the start and stop and size adjustment control buttons, which conforms to the user's usage habits of knob button regulation.

[0031] It is understandable that this embodiment does not limit the number, position layout and appearance of the blind holes 11 .

[0032] In this embodiment, the key pattern 12 is located on the shading layer 13 within the area surrounded by the corresponding blind hole 11 boundary, and is a hollow semi-transparent structure. In this way, the blind hole and the key pattern are combined to form corresponding function keys, which is convenient for user touch operation.

[0033] In this embodiment, there are four button patterns 12, the first button pattern 121 is the corresponding vehicle-mounted button volume pattern, the second button pattern 122 is the corresponding vehicle-mounted air-conditioning button pattern, the third button pattern 123 is the start-stop pattern, and the fourth button pattern 124 is the annular adjustment control button pattern. The first and second button patterns 121 and 122 correspond to the first and second blind holes 111 and 112 areas, and the third and fourth button patterns 123 and 124 correspond to the third blind hole 113 area.

[0034] In this embodiment, no specific setting is made for the pattern of each key pattern 12 .

[0035] In this embodiment, each key pattern 121, 122, 123, 124 corresponds to a touch pattern 31, and these touch patterns are ITO patterns made using ITO yellow light technology, corresponding to the function and position of the corresponding key pattern. In this embodiment, the ITO pattern includes the first, second, third, and fourth ITO patterns 311, 312, 313, and 314. The first ITO pattern 311 and the second ITO pattern 312 correspond to the first and second key patterns 121 and 122, and the setting function is to select air conditioning adjustment or volume adjustment. The third ITO pattern 313 corresponds to the third key pattern 113, and the setting function is to start and stop the selected function key module. The fourth ITO pattern 314 corresponds to the third key pattern 114, which is a ring pattern, and the size control of the selected function key is set. These ITO patterns are bound and connected to FPC5. It can be understood that different ITO patterns can be connected to the same FPC or to different FPCs.

[0036] In the first embodiment of this example, the edges of the ITO patterns 311, 312, 313, and 314 are made of metal wires by silk screen printing or yellow light process, and the metal wires corresponding to each pattern do not touch each other and are independent of each other. In this way, the metal wires only work in the local area of ​​the TIO pattern, and can build independent touch networks corresponding to different key patterns to form different touch functions. In this embodiment, the metal wires do not touch the FPC, making the TIO pattern more independent, and no external power supply or signal input is required, which can simplify the structure and manufacturing process to a certain extent.

[0037] In summary, the utility model designs multiple blind holes 11 and multiple buttons 12 on the cover plate 1 and designs corresponding touch patterns 31 on the touch glass 3, so that the operator can operate the touch knob without looking, thereby controlling the start and stop of the touch knob, switching the volume and air conditioning, adjusting the volume and the air conditioning temperature, and intuitively displaying the current control status of the vehicle air conditioning and volume on the LCD screen 4.

[0038] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
