[0046] In order to have a further understanding of the present invention, a preferred embodiment is given below with reference to the drawings:

[0047] See also Figures 2 to 5A key structure of a mobile phone protective shell, the mobile phone protective shell has a protective shell 10, the protective shell 10 has a back plate 11 and a frame 12 surrounding the back plate 11, the frame 12 forms a receiving space 13 for accommodating a mobile phone 1, 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 peripheral surface of the key positioning hole 14 is concavely provided with an engaging groove 15; the key positioning hole 14 of the protective shell 10 is provided with a touch button 2. The sensor key 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 peripheral surface of the combination frame 21 is provided with a ring flange 211, and the inner peripheral surface thereof is provided with an elastic sheet 23 protruding from its center, the elastic sheet 23 is a ring body formed by a thin sheet and has an end edge 231; the outer peripheral surface 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, each of which is provided with a plurality of through holes 242 arranged in a neat manner. The conductive members 25 are respectively arranged in each of the through holes 242, so that the two ends of the conductive members 25 are exposed from the surface of the key body 24 and are flush with the surface; and the one 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 combination frame 21 and the outer circumference of the key body 24; and the gasket 26 is a soft ring body, and its inner ring edge is provided with an axially protruding convex wall 261, and the gasket 26 is pressed against the side of the combination frame 21 facing the touch button 2, and the convex wall 261 is embedded in the inner peripheral edge of the combination frame 21; and the annular flange 211 of the combination frame 21 is embedded in the embedding groove 15 of the key positioning hole 14, so that the sensor key 20 is assembled on the protective shell 10, so that the key body 24, the conductive member 25 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 the 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.

[0048] The composition and function of the above embodiment are described in detail as follows: Figures 2 to 5As shown, the key body 24 of the utility model can be made of colloid or plastic material, which can cover and fix the conductive member 25; the conductive member 25 is made of a conductive material, and is made of a conductive metal material, a chemical metal composite material, etc. When the finger 3 touches the conductive member 25, 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 the position according to the difference in current change; furthermore, the gasket 26 can be made of a soft material such as silicone, etc., 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.

[0049] The combination 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 apply force to press the sensor key 20 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 can sense the user's pressing time, force and size... etc. to trigger the operation function.

[0050] 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 a finger 3 touches any position on the surface of the sensor key 20, it can touch one end of multiple conductive members 25. In this way, more touch signals of the finger 3 can be transmitted to the touch button 2 to improve the accuracy of touch sensing, and at the same time, the ability of the key body 24 to resist deformation can also be improved.

[0051] like Figure 5 As shown, when the finger 3 presses the key body 24 of the sensor key 20, the elastic sheet 23 is deformed to make the key body 24 sink, and the edge of the key body 24 does not rub against the combination frame 21 during the pressing process to generate obstruction, and one end of the conductive member 25 contacts the touch button 2, and the other end thereof is exposed outside the protective shell 10 to contact the finger 3. The pressure of the finger 3 pressing can be directly transmitted to the touch button 2 through the conductive member 25, and 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 also easier for the user to control the pressing force, thereby achieving the purpose of easy operation.

[0052] Furthermore, if the touch button 2 is disposed on the back of the mobile phone 1 (for example, for adjusting the focus when the camera is activated), according to the technology of the present invention, the sensor key 20 can also be disposed on the back panel 11 at a position corresponding to the touch button 2 .

[0053] In addition, according to the technology of the utility model, it is also possible to implement Figure 6 The combination frame 27 is designed to have any two elastic sheets 28 in opposite positions on its inner circumference and the key body 29 is designed to have two outer grooves 291 corresponding to the positions of the two elastic sheets 28 on its outer circumference. The end edges of the elastic sheets 28 are respectively embedded in the outer grooves 291 to fix the key body 29 on the combination frame 27. In other words, the elastic sheets 28 are arranged in sections, so that the key body 29 can be elastically pressed.

[0054] The above-mentioned embodiments are only preferred embodiments for fully illustrating the present invention, and are not intended to limit the features of the present invention. Any re-creation using the technical means and creation principles related to the present invention still falls within the scope of the equivalent structural creativity of the present invention.
