[0023] Please refer to Figures 2 to 5A key of a mobile phone protective shell is a protective shell 10 having a back plate 11 and a frame 12 surrounding the back plate 11, a receiving 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, the frame 12 of the protective shell 10 is provided with a key positioning hole 14 adapted to the shape of the touch button 2, the inner circumference of the key positioning hole 14 is radially protruded with an elastic extension ring piece 15; a sensor key 20 is provided in the key positioning hole 14 of the protective shell 10, and the sensor key 20 includes: a key frame 21, an inductive conductive component 22 and a gasket 2 3; wherein the key frame 21 is configured to fit the shape of the key positioning hole 14, the outer peripheral surface of the key frame 21 is convexly provided with a ring flange 211, and it has a through mounting hole 24, the mounting hole 24 has a small aperture section 241 close to the touch button 2 and a large aperture section 242 away from the touch button 2, and the small aperture section 241 of the mounting hole 24 is assembled with the inductive conduction component 22 to be fixed as a whole, and one end of the inductive conduction component 22 is convex to the direction of the touch button 2, and the other end thereof is flush with the hole edge of the small aperture section 241 adjacent to the large aperture section 242, so that the inductive conduction component The key frame 21 has a large aperture section 242 in the mounting hole 24 and a printed layer 243 on the surface of the sensing conductive component 22. A transparent covering sheet 244 is arranged on the printed layer 243, and the surface of the covering sheet 244 is flush with the surface of the key frame 21. The sensing conductive component 22 is provided with a plurality of neatly arranged conductive portions 221, each of which exposes two opposite surfaces of the sensing conductive component 22. The gasket 23 is a soft ring body, and the gasket 23 is attached to the elastic extension ring sheet 15 of the key positioning hole 14 facing the touch control. The sensor key 20 is assembled on the protective shell 10, and the gasket 23 is respectively abutted between the periphery of the touch button 2 of the mobile phone 1 and the key frame 21, and the inductive conductive component 22 corresponds to the touch button 2; when the user touches or applies pressure to the sensor key 20 with the finger 3, the touch button 2 receives the touch or pressure signal, and the mobile phone 1 generates the corresponding set action and function, so that the touch button 2 can be easily controlled.

[0024] The composition and function of the above embodiment are described in detail as follows: Figures 2 to 5As shown, the elastic extension ring piece 15 of the present utility model is a thin sheet ring integrally protruding from the protective shell 10, made of the same material as the protective shell 10, and the material 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 restore its shape when the external force is removed; and the key frame body 21 is made of materials including but not limited to hard plastic materials and can fix the induction conduction component 22. The combination of the elastic extension ring piece 15 and the ring flange 211 of the key frame body 21 can achieve the purpose of combination by means of bonding or overmolding. The printing layer 243 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 covering piece 244 is made of materials including but not limited to transparent materials such as sapphire, glass, and plastic sheets and can reveal the patterns of the printing layer 243. The conduction part 221 of the induction conduction component 22 can conduct the current of the finger 3, and the material includes but is not limited to conductive metal materials, chemical metal composite materials, or semiconductor materials. By touching the covering piece 244 with the finger 3, the touch signal can be conducted through the covering piece 244 and the printing layer 243 to the conduction part 221, and the conduction part 221 transmits the touch signal to the touch button 2. 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. Furthermore, the washer 23 is made of materials including but not limited to soft materials such as silica gel and foam, so that it has the ability of soft deformation and enables the sensing key 20 to closely fit around the touch button 2 of the mobile phone 1. In this way, when the user presses the sensing key 20 with the finger 3 to press against the touch button 2, the elastic extension ring piece 15 and the washer 23 can both elastically deform in response to the pressure change. By virtue of the induction conduction component 22 provided in the sensing key 20, the touch signal and the pressure value can be transmitted to the touch button 2, and the touch button 2 can sense the length, strength, and magnitude of the user's pressing time to trigger the operation function. In a preferred embodiment of the present utility model, the conduction parts 221 are arranged in an equidistant straight line and evenly distributed on the induction conduction component 22, so that when the finger 3 touches any position on the surface of the covering piece 244, the touch signal can be conducted to one end of at least one conduction part 221. In this way, the touch signal of the finger 3 can be transmitted to the touch button 2.

[0025] As Figure 5 shown, when the finger 3 presses the key frame body 21 of the sensing key 20, the elastic extension ring piece 15 and the washer 23 deform, causing the key frame body 21 to sink, and one end of the induction conduction component 22 to contact the touch button 2. The pressure of the finger 3 pressing can be directly transmitted to the touch button 2 through the induction conduction component 22. Since the induction conduction component 22 is made of non-elastic deformation material, the pressing force can be accurately transmitted, achieving the purpose of easy operation.

[0026] Furthermore, as Figure 6 shown, if the touch button 2 is arranged on the back surface of the mobile phone 1 (for example, applied to the focal length adjustment when the camera is enabled), 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.

[0027] The above-described embodiments are only preferred embodiments given 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.
