Please refer to Figures 2 to 5, a key structure of a mobile phone protective case (I), a protective case 10 having 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 frame 12, one edge of the mobile phone 1 has a touch button 2, the frame 12 of the protective case 10 is provided with a key positioning hole 14 adapted to the shape of the touch button 2, the inner peripheral surface of the key positioning hole 14 is concavely provided with an engaging groove 15; a sensor key 20 is provided in the key positioning hole 14 of the protective case 10, the sensor key 20 is provided in the The key sensing device 20 comprises: a combination frame 21, a key body 24, a plurality of conductive members 25 and a gasket 26; wherein the combination frame 21 is configured to fit the shape of the key positioning hole 14, the outer circumference of the combination frame 21 is provided with a convex edge 211, and the inner circumference thereof is provided with an elastic sheet 23 protruding toward the center, the elastic sheet 23 is a ring body surrounded by a thin sheet and has an end edge 231; the outer circumference of the key body 24 is provided with an outer groove 241, and the surface of the key body 24 is provided with a plurality of neatly arranged through holes 242, and each of the conductive members 25 is respectively assembled in each of the plurality of through holes 242. The through hole 242 is formed by two key covering sheets 243 respectively covering the surface of the key body 24 at both ends of the conductive member 25, so that the conductive members 25 are covered in the key body 24 and are not exposed; the end edge 231 of the elastic sheet 23 is embedded in the outer groove 241 of the key body 24, and a gap is formed between the inner circumference of the assembly frame 21 and the outer circumference of the key body 24; and the gasket 26 is a soft ring body, and an axially protruding convex wall 261 is provided on the inner circumference of the gasket 26, and the gasket 26 is abutted against the assembly frame 21 facing the touch button 2 The convex wall 261 is embedded in the inner peripheral edge of the assembly frame 21; the convex edge 211 of the assembly frame 21 is embedded in the fitting groove 15 of the key positioning hole 14, so that the sensor key 20 is assembled on the protective shell 10, and the key body 24 and the gasket 26 are in contact with the touch button 2; when the user touches or applies pressure to the sensor key 20 with a finger 3, the touch button 2 receives the touch or pressure signal, and the mobile phone 1 generates the corresponding setting action and function, so that the touch button 2 can be easily controlled.

The composition and function of the above-mentioned embodiment are described in detail as follows: As shown in Figures 2 to 5, the key body 24 of the present invention can be made of a rubber or plastic material, which can cover and fix the conductive member 25, and the key covering sheet 243 is made of materials including but not limited to glass, plastic, etc.; the conductive member 25 is a conductive material, such as a conductive metal material, a chemical metal composite material, etc., and the conductive member 25 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 according to the difference in current change; furthermore, the gasket 26 can be made of a soft material such as silicone, so that it has soft deformation ability, and through its slight adhesive properties, the sensor key 20 can be tightly attached to the touch button 2 of the mobile phone 1. In this way, the user can control the touch button 2 by just touching the surface of the sensor key 20, achieving a convenient and practical effect.

The assembly frame 21 can be made of plastic material, but is not limited thereto; and the elastic sheet 23 can be elastically deformed by external force and can restore its shape when the external force is released. In this way, the user can press the sensor key 20 with force, so that the sensor key 20 presses against the touch button 2. By filling the sensor key 20 with the conductive members 25, the sensor key 20 has excellent rigidity and can accurately transmit the pressure value to the touch button 2, so that the touch button 2 senses the user's pressing time, force and size... etc. to trigger the operation function.

In a preferred embodiment of the present invention, the conductive members 25 are arranged at equal intervals so as to be evenly distributed on the sensor key 20, and when the finger 3 touches any position on the surface of the sensor key 20, it can correspond to one end of multiple conductive members 25. In this way, more finger 3 touch signals can be transmitted to the touch button 2 to improve the accuracy of touch sensing, and at the same time, the key body 24 can also improve its ability to resist deformation.

As shown in Figure 5, when the finger 3 presses the key body 24 of the sensor key 20, the elastic sheet 23 deforms to make the key body 24 sink. The edge of the key body 24 does not rub against the support ring 22 during the pressing process to generate resistance. The pressure of the finger 3 is transmitted to the touch button 2 through the conductive member 25. The conductive member 25 is made of non-elastic deformable material, so the pressing force can be transmitted more accurately. At the same time, it is easier for the user to control the pressing force, achieving the purpose of easy control.

Furthermore, if the touch button 2 is disposed on the back of the mobile phone 1 (for example, for adjusting the focus when activating the camera), according to the technology of this invention, the sensor key 20 can also be disposed on the back panel 11 at a position corresponding to the touch button 2.

In addition, according to the technology of this invention, it is also possible to implement the form shown in Figure 6: the assembly frame 27 is set to have any two elastic sheets 28 in opposite positions on its inner circumference and the key body 29 is set to have two outer grooves 291 corresponding to the positions of the elastic sheets 28 on its outer circumference, and the end edges of each elastic sheet 28 are respectively embedded in the outer grooves 291 to fix the key body 29 on the assembly frame 27. In other words, the elastic sheet 28 is set in sections, so that the key body 29 can also achieve the purpose of being elastically pressed.

The above-mentioned embodiments are only preferred embodiments for fully explaining the present invention, and are not intended to limit the features of the present invention. Any re-creation using the relevant technical means and creation principles of the present invention still falls within the scope of the equivalent structural creativity of the present invention.
