[0024] Please refer to Figures 2 to 5, a button of a mobile phone case. A protective case 10 has a back plate 11 and a frame 12 surrounding the back plate 11. An accommodation space 13 for accommodating a mobile phone 1 is formed within the range of the frame 12. One edge of the mobile phone 1 has a touch button 2. A key positioning hole 14 adapted to the shape of the touch button 2 is provided on the frame 12 of the protective case 10. A sensing key 20 is provided in the key positioning hole 14 of the protective case 10. The sensing key 20 includes: an outer frame 21, an elastic ring 22, an outer ring support ring 23, an inner ring support ring 24, an induction conduction component 25, and a limiting ring 30. Wherein the outer frame 21 is configured to fit the shape of the key positioning hole 14, it has an outer surface 211 and an inner surface 212. The outer frame 21 is provided with a through hole 213 communicating the outer surface 211 and the inner surface 212, and the outer frame 21 is fixedly assembled in the key positioning hole 14. The outer edge of the elastic ring 22 is formed as a flat outer ring edge 221, and its inner edge is formed as a flat inner ring edge 222. A curved elastic section 223 is formed between the outer ring edge 221 and the inner ring edge 222. The outer ring support ring 23 corresponds to the shape of the outer ring edge 221, and it is attached to the side of the outer ring edge 221 facing away from the touch button 2, and the side of the outer ring support ring 23 facing away from the outer ring edge 221 is attached to the inner surface 212 of the outer frame 21. The inner ring support ring 24 corresponds to the shape of the inner ring edge 222, and it is attached to the side of the inner ring edge 222 facing away from the touch button 2, and the inner ring support ring 24 is attached to the outer edge of the induction conduction component 25, and one end of the induction conduction component 25 protrudes in the direction of the touch button 2, so that the induction conduction component 25 corresponds to the touch button 2. A plurality of conduction parts 251 arranged neatly and pointing in the direction of the touch button 2 are arranged on the induction conduction component 25, and each of the conduction parts 251 exposes two opposite surfaces of the induction conduction component 25. A printing layer 252 is provided on the surface of the induction conduction component 25 facing away from the touch button 2, and then a transparent covering piece 253 is provided on the printing layer 252, and the covering piece 253 and the induction conduction component 25 can be exposed through the through hole 213 of the outer frame 21. A protective coating 254 extending to the peripheral side surface is provided on the surface of the induction conduction component 25 facing the touch button 2, and a flange 255 is provided on the outer periphery of the induction conduction component 25 away from the touch button 2, and the side of the inner ring support ring 24 facing away from the inner ring edge 222 is attached to the flange 255. The cross section of the limiting ring 30 is formed in an "L" shape and has an axial fixing piece 31 and a limiting piece 32 extending radially towards the center. One end of the fixing piece 31 is attached to the side of the outer ring edge 221 facing away from the outer ring support ring 23. The limiting piece 32 is connected to the end of the fixing piece 31 facing away from the outer ring edge 221, and the length of the limiting piece 32 extends to the position corresponding to the inner ring edge 222, and a washer 33 is provided on the side of the limiting piece 32 facing the touch button 2, and the sensing key 20 is fixedly assembled on the protective case 10;By the user touching or applying pressure to the sensing key 20 with a finger 3, the touch button 2 receives a touch or pressure signal, and the mobile phone 1 generates corresponding setting actions and functions, achieving the effect of easily controlling the touch button 2.

[0025] The composition, function, and effect of the above embodiments are described in detail as follows: As Figures 2 to 5As shown, the material of the outer frame 21 of the present utility model includes, but is not limited to, metal or plastic rigid materials, which can firmly fix the sensing key 20 in position; the material of the elastic ring 22 includes, but is not limited to, soft elastic materials such as silica gel, rubber, and plastic, so that it can be elastically deformed by external force and restore its shape when the external force is removed; the materials of the outer ring support ring 23 and the inner ring support ring 24 include, but are not limited to, metal or plastic rigid materials, especially stainless steel metal, mainly because it is harder and not easily deformed, and its thickness can be relatively thinner than other materials. With the reinforcement of the outer ring support ring 23 and the inner ring support ring 24, the outer edge and inner edge of the elastic ring 22 can remain flat and unchanged. When the elastic ring 22 elastically changes, the pressing force can be evenly distributed on the elastic ring 22, so that the sensing key 20 can be pressed smoothly, avoiding the situation of poor touch caused by the sensing key 20 warping. The printing layer 252 can be coated or printed with decorative colors, patterns, graphics, lines, or reticulations according to the user's needs, making the sensing key 20 more diverse; the material of the covering piece 253 includes, but is not limited to, transparent materials such as sapphire, glass, and plastic sheets, and can transmit the patterns of the printing layer 252. The material of the protective coating 254 includes, but is not limited to, materials such as ink, paint, and silica gel, which prevent the induction conduction component 25 from directly contacting and rubbing against the touch button 2, thereby protecting the contacts of the conduction part 251 and avoiding scratching the surface of the touch button 2. The conduction part 251 of the induction conduction component 25 can conduct the current of the finger 3, and its material includes, but is not limited to, conductive metal materials, chemical metal composite materials, or semiconductor materials. By touching the covering piece 253 with the finger 3, the touch signal can be conducted through the covering piece 253 and the printing layer 252 to the conduction part 251, and the conduction part 251 transmits the touch signal to the touch button 2 through the protective coating 254. At this time, the controller of the touch button 2 will calculate the position of the finger 3 and the function represented by that position based on the difference in current changes. In this way, the user can apply force to press the sensing key 20, making the sensing key 20 press against the touch button 2. Since the sensing key 20 is provided with the induction conduction component 25, the pressure value can be transmitted to the touch button 2, enabling the touch button 2 to sense the length, strength, and magnitude of the user's pressing time to trigger the operation function. The washer 33 can be made of a soft material such as silica gel, so that it has the ability to deform softly. Moreover, due to its slight adhesive property, the sensing key 20 can closely adhere to the periphery of the touch button 2 of the mobile phone 1. In this way, the user can control the touch button 2 only by touching the surface of the sensing key 20, achieving a convenient practical effect.

[0026] In a preferred embodiment of the present utility model, these conduction parts 251 are arranged at equal intervals in a line so that they are evenly distributed on the induction conduction assembly 25. When the finger 3 touches any position on the surface of the covering piece 253, a touch signal can be conducted to one end of at least one conduction part 251. In this way, the touch signal of the finger 3 can be transmitted to the touch button 2.

[0027] As Figure 5 shown, when the finger 3 presses the sensing key 20 through the through hole 213, the curved elastic section 223 of the elastic ring 22 is stretched or squeezed and deformed, causing the induction conduction assembly 25 to sink, and one end of it abuts against the touch button 2. The pressing force of the finger 3 can be directly transmitted to the touch button 2 through the induction conduction assembly 25. Since the induction conduction assembly 25 is made of a non-elastically deformable material, the pressing force can be transmitted more accurately. At the same time, for the user, it is also easier to control the pressing force, achieving the purpose of being easily operable. It is worth mentioning that the material of the limiting ring 30 includes but is not limited to rigid materials such as plastics. When pressing the induction conduction assembly 25, the limiting piece 32 can limit the pressing stroke of the induction conduction assembly 25, so that the limiting piece 32 blocks the induction conduction assembly 25 from sinking excessively, and can block the excessive pressing force of the finger 3, avoiding the touch button 2 directly bearing a large pressing force resulting in wear or scratches on its surface, achieving the effect of protecting the touch button 2.

[0028] Furthermore, as Figure 6 shown, if the touch button 2 is arranged on the back of the mobile phone 1 (for example, applied to the focal length adjustment when enabling the camera), according to the technology of the present utility model, the sensing key 20 can also be arranged at the position on the back plate 11 corresponding to the touch button 2.

[0029] The above-described embodiments are only preferred embodiments cited to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present utility model are all within the protection scope of the present utility model. The protection scope of the present utility model is subject to the claims.
