[0050] To have a further understanding of the present utility model, a preferred embodiment is given below in conjunction with the drawings and described in detail as follows:

[0051] Please refer to Figures 2 to 5, a button of a mobile phone case. The mobile phone case has a protective case 10, which has a back plate 11 and a frame 12 surrounding the back plate 11. A receiving space 13 for receiving 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, which 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 assembled and fixed in the key positioning hole 14; the outer edge of the elastic ring 22 is configured as a flat outer ring edge 221, the inner edge of the elastic ring 22 is configured as a flat inner ring edge 222, and a curved elastic section 223 is provided 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 is attached to the side of the outer ring edge 221 away from the touch button 2, and the side of the outer ring support ring 23 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 is attached to the side of the inner ring edge 222 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; several 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 respectively 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 away from the touch button 2, and 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. An annular flange 255 is provided on the outer peripheral edge of the induction conduction component 25 away from the touch button 2, and a stop piece 256 protrudes on the outer peripheral edge of the annular flange 255. The side of the inner ring support ring 24 away from the inner ring edge 222 is attached to the annular flange 255; the outer peripheral contour of the stop piece 256 is larger than the edge of the through hole 213, so as to limit the induction conduction component 25 from passing through the through hole 213 and detaching; the cross section of the limiting ring 30 is configured as an L shape and has an axial fixing piece 31 and a limiting piece 32 extending radially toward the center. One end of the fixing piece 31 is attached to the side of the outer ring edge 221 away from the outer ring support ring 23;The limiting piece 32 is connected to one 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, so that the sensing key 20 is assembled and positioned on the protective shell 10; by the user touching or applying pressure to the sensing key 20 with the finger 3, the touch button 2 receives the 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.;

[0052] The composition, functions and effects 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 under external force and can 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 is preferred. The main reason is that in addition to being relatively hard and not easily deformed, its thickness can be relatively thinner than other materials. Under 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 be kept flat and unchanged in shape, so that when the elastic ring 22 changes elastically, the pressing force can be evenly distributed on the elastic ring 22, making the sensing key 20 press smoothly and avoiding the situation of poor touch caused by the sensing key 20 warping. The printing layer 252 can be coated and printed with decorative colors, patterns, graphics, lines, or reticulations and other patterns 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 and 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... to prevent the induction conduction component 25 from directly contacting and rubbing with 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, electrically conductive metal materials, chemical metal composite materials, or semiconductor materials... etc. By using the finger 3 to touch the covering piece 253, 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, so that the sensing key 20 presses against the touch button 2. By virtue of the induction conduction component 25 provided in the sensing key 20, the pressure value can be transmitted to the touch button 2, so that the touch button 2 can sense the length, strength, and magnitude of the user's pressing time... etc. to trigger the operation function. In this way, the user can control the touch button 2 only by touching the surface of the sensing key 20, achieving a convenient and practical effect.

[0053] In a preferred embodiment of the present utility model, the conduction parts 251 are arranged at equal intervals in a straight line so that they are evenly distributed on the induction conduction component 25, and when the finger 3 touches any position on the surface of the covering piece 253, the touch signal can be conducted to at least one end of a conduction part 251. In this way, the touch signal of the finger 3 can be transmitted to the touch button 2.

[0054] As Figure 5As 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 component 25 to sink, and one end of it abuts against the touch button 2. The pressure applied by the finger 3 can be directly transmitted to the touch button 2 through the induction conduction component 25. Since the induction conduction component 25 is made of a non-elastic deformation 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 easy operation.

[0055] It is worth mentioning that since the stop piece 256 of the induction conduction component 25 is blocked by the inner surface 212 around the through hole 213, the induction conduction component 25 cannot pass through the through hole 213. When pressing the induction conduction component 25, the limiting piece 32 can limit and block the pressing stroke of the induction conduction component 25, so that the limiting piece 32 blocks the induction conduction component 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, which may cause wear or scratches on its surface. By using the stop piece 256 and the limiting ring 30 to limit the pressing stroke of the induction conduction component 25 respectively, even if the adhesives between the elastic ring 22 and the outer frame 21 and the induction conduction component 25 fail (i.e., delaminate) after long-term use, the induction conduction component 25 will not fall off from the sensing key 20, enabling the sensing key 20 to still be used continuously, achieving the better effect of its use value.

[0056] 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.

[0057] The above-described embodiments are only preferred embodiments given to fully illustrate the present utility model, and are not intended to limit the features of the present utility model. Any re-creation using the related technical means and creation principles of the present utility model still belongs to the scope of the equivalent structure creativity of the present utility model.
