[0024] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the relevant drawings. The drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0025] It should be noted that "hollowing out" in this article refers to removing certain parts from an object. The terms "front side", "back side" and similar expressions used in this article are only for the purpose of illustration and do not represent the only implementation method.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] refer to Figures 1 to 3 The touch knob button of the first embodiment includes a cover plate 1, a bonding adhesive layer 2, a touch sensing glass 3, and an FPC 4. The front side of the cover plate 1 is provided with an annular blind groove 11, and the back side of the cover plate 1 is provided with a shading layer 12. The shading layer 12 includes a shading area 121 and a pattern area 122. The pattern area 122 is a hollow structure, and the pattern area 122 is light-transmitting. The back side of the cover plate 1 is bonded to the touch sensing glass 3 through the bonding adhesive layer 2. A touch pattern 31 is provided on the bonding surface of the touch sensing glass 3, and the touch pattern 31 is located in the contour enclosed area of ​​the pattern area 122. The FPC 4 is bound to the touch sensing glass 3.

[0028] In this embodiment, the bonding adhesive layer 2 is an OCR or OCA adhesive layer with a thickness of 0.15 mm, and the adhesive layer 2 is fully bonded to the cover plate 1 and the touch sensing glass 3 .

[0029] In this embodiment, the shading layer 12 is a double-layer shading ink layer, and the shading ink is screen-printed on the back of the cover plate. On the one hand, it can better prevent impurities, bubbles, etc. on the cover plate 1 from being transmitted or reflected, affecting the display effect. On the other hand, it improves the adhesion, wear resistance, scratch resistance and weather resistance of the shading layer.

[0030] In this embodiment, the pattern area 122 is located on the light shielding layer 12, and a layer of semi-transparent ink is hollowed out and silk-screened, and then a layer of diffusion ink is silk-screened to form a semi-transparent structure, so that a pattern can be displayed on the cover plate 1. The pattern area 122 includes a start-stop indication pattern and an annular pattern, which is used to operate the start-stop and the required range of temperature, volume, brightness, speed, etc. The pattern area 122 is located in the area surrounded by the annular blind groove 11.

[0031] It is understandable that this embodiment does not constitute a specific limitation on the graphic style of the pattern area 122 .

[0032] The operating principle of this embodiment is as follows: after the pattern area 122 is hollowed out and light-transmitting, it is displayed in the annular blind groove 11 of the cover plate 1. The user touches the corresponding pattern on the annular blind groove 11 on the knob button, and transmits the sensing signal through the touch pattern 31 on the touch sensing glass 3 through the FPC connection, thereby achieving the matching of the touch knob button with the user's operation.

[0033] refer to Figures 4 to 6 In the second embodiment, the cover plate 1 is an annular cover plate, and the cover plate 1 is made of a substrate of 0.7-3.0 mm thick tempered glass machined. The annular blind groove 11 on the cover plate is located in the center of the cover plate 1, and is made by etching or machining. The width of the annular blind groove 11 is 10-15 mm, and the depth is 0.2-0.5 mm. The bonding adhesive layer uses an OCR or OCA adhesive layer with a thickness of 0.3 mm.

[0034] In this embodiment, the touch pattern 31 on the touch glass 3 adopts an ITO (indium tin oxide) pattern, and the ITO pattern is designed as an integral whole. An auxiliary conductive line 32 is provided at the edge of the touch sensing glass 3. The auxiliary conductive line 32 is a metal line with any one of gold, silver, copper, aluminum, molybdenum, and nickel as the main component, and is routed by direct silk screen printing or yellow light process. The line surrounds the above-mentioned ITO pattern, and one end is connected to the ITO pattern, and the other end is connected to the FPC4. In this way, the auxiliary conductive line 32 is bound and connected to the FPC through the contact point, and the electronic signal can be transmitted from the ITO pattern to the FPC, and from the FPC to the ITO pattern, so that the touch sensing is more sensitive, and contacting the FPC can ensure that the power supply is stably supplied to the ITO pattern.

[0035] In summary, the utility model has a simple structure and can be widely used in touch knob control scenarios requiring various functions, and can replace the circular control function of traditional physical knob buttons, so that even users who are accustomed to traditional physical knob buttons can quickly adapt.

[0036] 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.
