In a first aspect, the present utility model proposes a mobile phone key 100, referring to fig. 1, the mobile phone key 100 includes a frame 10, a supporting portion 30, a bump 20, and a piezoelectric device 40.

For the above-mentioned frame 10, referring to fig. 1 and 2, the frame 10 may be configured as a rectangular frame 10 that is consistent with the outline of the mobile phone 1000, for example, the frame 10 includes four connection bars (not labeled in the drawing), and the four connection bars are integrally formed to form the above-mentioned rectangular frame 10. And the four connecting rods together enclose an installation space (not labeled in the figure), and the main body part (not labeled in the figure) of the mobile phone 1000 can be installed in the installation space, that is, the frame 10 is arranged at the edge of the mobile phone 1000 to integrally wrap the main body part of the mobile phone 1000.

The frame 10 has a pressing section 11, and the pressing section 11 may be a part of a top connecting rod of the frame 10, or may be a part of a bottom or left and right connecting rod. Pressing the pressing section 11 outside the frame 10 can deform the pressing section 11 to a certain extent. Further, referring to fig. 3, the pressing section 11 has a first surface 111 and a second surface 112 disposed opposite to each other, the first surface 111 is disposed away from the mounting space, and can be used to touch the mobile phone key 100 externally, the second surface 112 faces the mounting space, and when the pressing section 11 is pressed, the second surface 112 can apply the deformation generated by the pressing section to the piezoelectric device 40.

For the above-mentioned supporting portion 30, referring to fig. 3, the supporting portion 30 includes a first supporting member 31 and a second supporting member 32, the first supporting member 31 and the second supporting member 32 are respectively connected to two ends of the second surface 112, and the first supporting member 31 and the second supporting member 32 may be configured as a cylinder or a cuboid for supporting the pressing section 11 to ensure that the elastic deformation of the pressing section 11 reduces the plastic deformation thereof.

The first supporting member 31 and the second supporting member 32 may be disposed in a clamping manner with the pressing section 11, for example, referring to fig. 4, a first limiting groove 113 is formed on an end surface of the pressing section 11 facing the first supporting member 31, and a first limiting portion 311 is protruding on an end surface of the first supporting member 31 facing the pressing section 11, where the first limiting portion 311 is clamped to the first limiting groove 113, so that the first supporting member 31 is clamped to the pressing section 11. The end face of the pressing section 11 facing the second support piece 32 is provided with a second limiting groove 114, the end face of the second support piece 32 facing the pressing section 11 is convexly provided with a second limiting part 321, and the second limiting part 321 is clamped in the second limiting groove 114, so that the second support piece 32 is clamped with the pressing section 11. Through the clamping connection arrangement of the first supporting piece 31 and the second supporting piece 32 with the pressing section 11, the later frame 10 and the mobile phone 1000 are convenient to disassemble and maintain.

In other embodiments, the first support 31 and the second support 32 may be integrally formed with the pressing section 11, so as to reduce loosening of the pressing section 11, and ensure stable installation of the first support 31 and the second support 32 with the pressing section 11.

For the above-mentioned bump 20, referring to fig. 1 and 5, the bump 20 is disposed on the second surface 112 of the pressing section 11 and located between the first supporting member 31 and the second supporting member 32. When the pressing section 11 is pressed outside the frame 10, the pressing section 11 deforms, and the deformation is concentrated on the bump 20, so that the bump 20 gradually approaches and contacts the piezoelectric device 40 to transmit the acting force to the pressing device, thereby forming the tactile feedback.

For example, the bump 20 is disposed at a central position of the pressing section 11, so that the pressing section 11 is more easily deformed during external pressing.

In some embodiments, the pressing section 11, the supporting portion 30 and the bump 20 can be integrally formed, and the integrally formed mobile phone key 100 has good stability, and the supporting portion 30 and the bump 20 are not easy to loosen.

In some embodiments, in a state that the mobile phone key 100 is released, a first gap is formed between the bump 20 and the piezoelectric device 40, the first gap is L, which satisfies 0.05mm < L < 0.1mm, when the pressing section 11 receives an external force and generates small deformation, the bump 20 can abut against the piezoelectric device 40, and the piezoelectric device 40 senses the deformation and can generate an electrical signal.

As for the piezoelectric device 40, referring to fig. 1 and 6, the piezoelectric device 40 is connected between the first support 31 and the second support 32, and the deformation is concentrated on the bump 20 to be in contact with the piezoelectric device 40 in a state where the pressing section 11 is pressed down. In order to make the piezoelectric device 40 and the bump 20 conveniently contact, the piezoelectric device is disposed under the bump 20, for example, a first clamping groove 312 is formed in an end face of the first supporting member 31 facing the second supporting member 32, a second clamping groove 322 is formed in an end face of the second supporting member 32 facing the first supporting member 31, one end of the piezoelectric device 40 is clamped in the first clamping groove 312, the other end is clamped in the second clamping groove 322, and the piezoelectric device 40 is clamped in the first supporting member 31 and the second supporting member 32, so that the piezoelectric device 40 can be well fixed.

In some embodiments, the end surface of the bump 20 facing the piezoelectric device 40 is provided with a buffer layer (not labeled in the figure), for example, the end surface is provided with a part of a rubber layer or other flexible layer, when the pressing section 11 is pressed, the buffer layer directly contacts with the piezoelectric device 40, and the buffer layer can relieve the impact force generated after the bump 20 abuts against the piezoelectric device 40, so as to reduce the damage to the pressing device caused by violent pressing.

In some embodiments, the end surface of the bump 20 facing the piezoelectric device 40 is a spherical surface, and when the bump 20 contacts the piezoelectric device 40, the contact surface between the spherical surface and the piezoelectric device 40 is gradually increased, and the contact between the spherical surface and the piezoelectric device 40 is smoother, so that damage to the piezoelectric device 40 can be reduced.

In some embodiments, referring to fig. 6, the mobile phone key 100 further includes a first electrode 50 and a second electrode 60, the first electrode 50 and the second electrode 60 are disposed on an end surface of the piezoelectric device 40 facing away from the bump 20, and the first electrode 50 and the second electrode 60 are electrically connected to the piezoelectric device 40. The tactile feedback is formed by transmitting electrical signals through the first electrode 50 and the second electrode 60. Specifically, when the pressing section 11 is pressed so that the bump 20 is in contact with the piezoelectric device 40, when the piezoelectric device 40 senses the deformation and generates a first electric signal, the first electric signal is transmitted to the control system of the mobile phone 1000 through the first electrode 50 and the second electrode 60, the system recognizes the first electric signal and generates a response, for example, the volume is increased, that is, the increase of the volume can be displayed on the screen, the audible volume becomes large, the control system outputs a second electric signal, the first electrode 50 and the second electrode 60 output the second electric signal, the piezoelectric device 40 receives the returned second electric signal, and in response to forming vibration, the vibration is transmitted to the pressing section 11 through the bump 20 to form a tactile feedback, that is, the user touches the pressing section 11 and can feel the vibration.

In the embodiment of the present utility model, the mobile phone key 100 includes a frame 10, a supporting portion 30, a bump 20 and a piezoelectric device 40. The bezel 10 includes a pressing section 11, the pressing section 11 having a first surface 111 and a second surface 112 disposed opposite to each other.

The bump 20 is disposed on the second surface 112 and located between the first support 31 and the second support 32. The piezoelectric device 40 is connected between the first support 31 and the second support 32, and the bump 20 abuts against the piezoelectric device 40 in a state where the pressing section 11 is pressed down. According to the mobile phone key 100 provided by the utility model, the frame 10 is provided with the pressing section 11, namely, the operation of pressing the mobile phone key 100 can be realized by directly pressing the pressing section 11 of the frame 10.
