An annular flange 211 is provided on the outer peripheral surface of the outer frame 21, and it has a through hole 212 communicating with its inner peripheral surface; The support ring 22 is assembled on the inner peripheral surface of the outer frame 21; The cross section of the curved elastic wall 23 is a loop formed by a thin sheet winding, and it has an outer side 231 and an inner side 232. And it is assembled on the support ring 22 with the outer side 231; The key frame body 24 is provided with a mounting hole 241, and the mounting hole 241 is assembled with the induction conduction component 25 to be fixed as a whole, and one end of the induction conduction component 25 protrudes in the direction of the touch button 2, and the other end is recessed on the surface of the key frame body 24 to form a groove space 242. A printing layer 243 is provided on the surface of the induction conduction component 25 in the groove space 242, and then a transparent covering sheet 244 is provided on the printing layer 243, and the surface of the covering sheet 244 is flush with the surface of the key frame body 24. A plurality of neatly arranged conduction parts 251 are arranged on the induction conduction component 25. Each of the conduction parts 251 exposes two opposite surfaces of the induction conduction component 25, and the inner side 232 of the curved elastic wall 23 is embedded on the outer side surface of the key frame body 24, so that the key frame body 24 and the induction conduction component 25 can be exposed from the through hole 212 of the outer frame 21; The cross section of the extension ring 26 is an L-shaped loop, so that it has an axial first plate 261 and a second plate 262 extending radially towards the center of the loop. The first plate 261 is attached to the inner peripheral surface of the outer frame 21, and one end of the first plate 261 is clamped between the outer frame 21 and the support ring 22; And the washer 27 is a soft loop. The washer 27 is attached to one side of the outer frame 21 facing the touch button 2 and the second plate 262 of the extension ring 26; And the annular flange 211 of the outer frame 21 is embedded in the fitting groove 15 of the key positioning hole 14, so that the sensing key 20 is fixed on the case 10, the washer 27 abuts against the periphery of the touch button 2 of the mobile phone 1, and the induction conduction component 25 corresponds to the touch button 2; 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.

[0024] The composition and functions of the above embodiments are described in detail as follows: As Figures 2 to 5 shown, the key housing 24 of the present utility model can be made of a gelatinous or plastic material, and can fix the induction conduction component 25; the printing layer 243 can be coated and 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 can be made of a transparent material such as sapphire, and can transmit the patterns of the printing layer 243. The conduction part 251 of the induction conduction component 25 can conduct the current of the finger 3, and is made of a conductive metal material, a chemical metal composite material, etc. 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 251, and the conduction part 251 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 27 can be made of a soft material such as silicone, but not limited thereto, so that it has the ability to deform softly, and enables the sensing key 20 to closely fit on the touch button 2 of the mobile phone 1.

[0025] The outer frame 21 and the support ring 22 can be made of a hard material such as plastic or metal, but not limited thereto, so that the outer side 231 of the curved elastic wall 23 can be firmly fixed in the support ring 22 without falling off; and the curved elastic wall 23 is made of an elastic rubber or plastic soft material, so that it can be elastically deformed by an external force and can return to its original shape when the external force is removed. 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 senses the length, strength, and magnitude of the user's pressing time to trigger the operation function.

[0026] In a preferred embodiment of the present utility model, the conduction parts 251 are arranged at equal intervals and are evenly distributed on the induction conduction component 25, so that when the finger 3 touches any position on the surface of the covering piece 243, the 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 5As shown, when the finger 3 presses the key frame body 24 of the sensing key 20 through the through hole 212, the curved elastic wall 23 deforms to sink the key frame body 24, and one end of the induction conduction component 25 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.

[0028] Furthermore, 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 invention, 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 given to fully illustrate the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present invention are all within the protection scope of the present invention. The protection scope of the present invention is subject to the claims.
