The knob 2 is connected to the rotary potentiometer 1, and the knob circuit board 3 is electrically connected to the rotary potentiometer 1. The NFC antenna 4 is arranged on the outer peripheral side of the rotary potentiometer 1, and the NFC antenna 4 is electrically connected to the knob circuit board 3.

[0045] Among them, inward refers to: the direction of the axis of the rotary potentiometer 1 on a plane perpendicular to the axis of the rotary potentiometer 1; outward refers to: the direction of the axis of the rotary potentiometer 1 on a plane perpendicular to the axis of the rotary potentiometer 1. The NFC antenna 4 is arranged on the outer peripheral side of the rotary potentiometer 1, which can be understood as: the rotary potentiometer 1 is closer to the axis of the rotary potentiometer 1 than the NFC antenna 4. For example, the NFC antenna 4 can be ring-shaped, and the NFC antenna 4 is sleeved on the outer peripheral side of the rotary potentiometer 1.

[0046] The mechanical key 100 of the disclosed embodiment has a knob function by connecting the knob 2 to the rotary potentiometer 1, and the rotary potentiometer 1 is electrically connected to the knob circuit board 3, so that the mechanical key 100 has a knob function. For example, the volume, brightness, temperature, etc. can be adjusted by turning the knob 2; the NFC antenna 4 is arranged on the outer peripheral side of the rotary potentiometer 1, and the NFC antenna 4 is electrically connected to the knob circuit board 3, so that the mechanical key 100 has an NFC function. As a result, the NFC function is integrated on the mechanical key 100, avoiding the NFC antenna from occupying additional space outside the mechanical key 100, reducing the overall occupied space of the mechanical key 100 and the NFC antenna 4, and facilitating the layout of the mechanical key 100 and the NFC antenna 4. In addition, only the mechanical key 100 needs to be installed, and the NFC antenna 4 can be installed at the same time, which can improve the overall installation efficiency of the mechanical key 100 and the NFC antenna 4.

[0047] Optionally, the mechanical button 100 includes a flexible circuit board, the NFC antenna 4 is disposed on the flexible circuit board, and the flexible circuit board is electrically connected to the knob circuit board 3 .

[0048] By setting the NFC antenna 4 on the flexible circuit board, it is helpful to reduce the thickness of the NFC antenna 4, reduce the space occupied by the NFC antenna 4 outside the rotary potentiometer 1, and facilitate the integration of the NFC antenna 4 on the mechanical button 100. In addition, it is also conducive to the miniaturization and lightweight design of the mechanical button 100.

[0049] In some embodiments, Figure 2 , Figure 6 and Figure 7 As shown, the mechanical button 100 further includes an NFC bracket 5, which is disposed on the outer peripheral side of the rotary potentiometer 1, and the NFC antenna 4 is connected to the NFC bracket 5. The NFC bracket 5 is connected to the knob circuit board 3, and the NFC antenna 4 is electrically connected to the knob circuit board 3.

[0050] The NFC antenna 4 and the NFC bracket 5 can be bonded, the NFC bracket 5 and the knob circuit board 3 can be bonded, and the NFC antenna 4 and the knob circuit board 3 can be welded. The NFC bracket 5 can be annular, and the NFC bracket 5 is sleeved on the outer peripheral side of the rotary potentiometer 1.

[0051] By providing the NFC bracket 5, when the NFC antenna 4 is connected to the knob circuit board 3, the NFC antenna 4 is first mechanically connected to the NFC bracket 5, and then the NFC bracket 5 is mechanically connected to the knob circuit board 3, and the NFC antenna 4 is electrically connected to the knob circuit board 3, so as to facilitate the installation and fixation of the NFC antenna 4. In addition, when the NFC antenna 4 is formed on a flexible circuit board, the NFC bracket 5 can also be used to support the NFC antenna 4 so that the NFC antenna 4 is connected to the knob circuit board 3.

[0052] Alternatively, if Figure 3 and Figure 6 As shown, the NFC antenna 4 includes an antenna body 41 and a connecting piece 42. The antenna body 41, the NFC bracket 5 and the knob circuit board 3 are stacked, and the NFC bracket 5 is arranged between the antenna body 41 and the knob circuit board 3. One end of the connecting piece 42 is electrically connected to the antenna body 41, and the other end of the connecting piece 42 is electrically connected to the knob circuit board 3, so that the antenna body 41 and the knob circuit board 3 are electrically connected.

[0053] By configuring the NFC antenna 4 to include an antenna body 41 and a connecting piece 42, the antenna body 41 is used to facilitate the mechanical connection between the NFC antenna 4 and the knob circuit board 3, and the connecting piece 42 is used to facilitate the electrical connection between the NFC antenna 4 and the knob circuit board 3. This facilitates the assembly of the mechanical button 100 and helps reduce the cost of the mechanical button 100.

[0054] Alternatively, if Figure 7 As shown, the connecting piece 42 includes a first section 421 and a second section 422, and the extension direction of the first section 421 intersects with the extension direction of the second section 422.

The second section 422 and the knob circuit board 3 can be welded.

[0055] For example, the first section 421 is parallel to the thickness direction of the antenna body 41, the second section 422 is perpendicular to the thickness direction of the antenna body 41, the first section 421 is bonded to the side of the NFC bracket 5, and the second section 422 is bonded to the surface of the knob circuit board 3 facing away from the NFC bracket 5.

[0056] By setting the connecting piece 42 to include a first section 421 and a second section 422, the extension direction of the first section 421 intersects with the extension direction of the second section 422, and the second section 422 is used to be electrically connected to the knob circuit board 3, which further facilitates the electrical connection between the NFC antenna 4 and the knob circuit board 3, which is beneficial to further reduce the cost of the mechanical button 100.

[0058] For example, a positioning protrusion 51 is disposed on the outer peripheral surface of the NFC bracket 5 , and a positioning hole 4211 is disposed on the first section 421 .

[0059] When assembling the NFC antenna 4 and the NFC bracket 5, the positioning protrusion 51 can be first positioned and matched with the positioning hole 4211 to achieve pre-positioning between the NFC antenna 4 and the NFC bracket 5, and then the NFC antenna 4 and the NFC bracket 5 are connected. The connection between the NFC antenna 4 and the NFC bracket 5 is convenient, which is conducive to further reducing the cost of the mechanical button 100.

[0060] Alternatively, if Figure 6 As shown, the mechanical button 100 also includes a knob bracket 20, which is arranged on the side of the knob circuit board 3 facing away from the NFC bracket 5 and connected to the knob circuit board 3. The knob bracket 20 has a bracket surface 201 arranged toward the knob circuit board 3. The orthographic projection of the antenna body 41 on the bracket surface 201 is located on the inner side of the edge of the bracket surface 201. In other words, the edge of the antenna body 41 is located on the inner side of the edge of the bracket surface 201. Among them, the knob bracket 20 and the knob circuit board 3 can be connected by a first screw 501.

[0061] By setting the edge of the antenna body 41 to be located inside the edge of the bracket surface 201 , it is possible to avoid the antenna body 41 from occupying additional space outside the knob bracket 20 , which is beneficial to the miniaturized design of the mechanical button 100 .

[0062] Optionally, the orthographic projection of the NFC bracket 5 on the bracket surface 201 is located inside the edge of the bracket surface 201. In other words, the edge of the NFC bracket 5 is located inside the edge of the bracket surface 201.

[0063] By setting the edge of the NFC bracket 5 to be located inside the edge of the bracket surface 201 , it is possible to avoid the NFC bracket 5 from occupying additional space outside the knob bracket 20 , which is beneficial to the miniaturized design of the mechanical button 100 .

The mechanical key 100 also includes a main board 6, a key switch 7, a key bracket 8 and a key panel 9, wherein the main board 6 is arranged on a side of the rotary potentiometer 1 away from the knob 2. The base 11 has a base hole 111, wherein the key switch 7 is arranged corresponding to the base hole 111 and is electrically connected to the main board 6, and at least a portion of the key bracket 8 is arranged in the base hole 111 and is connected to the base 11. The key panel 9 is connected to an end of the key bracket 8 facing away from the main board 6.

[0065] The rotary potentiometer 1 further includes a conductive sheet 13, which is electrically connected to the knob circuit board 3. The rotating seat 12 may be annular, and the rotating seat 12 is sleeved on the outer peripheral side of the base 11. The knob 2 may also be arc-shaped, and the knob 2 is sleeved on the outer peripheral side of the rotating seat 12.

[0066] During specific use, by pressing the button panel 9, the button bracket 8 can be driven to move in the direction toward the button switch 7, so that the button bracket 8 triggers the button switch 7, and then the button switch 7 is used to control and implement corresponding functions, for example, the pause function of audio and video.

[0067] By providing the button assembly, the mechanical button 100 has not only a knob function but also a button function, thereby further improving the integration of the mechanical button 100 .

[0068] In some embodiments, Figure 4 and Fig.10 As shown, the base 11 includes a first connecting section 112 and a second connecting section 113 , the rotating base 12 is sleeved on the first connecting section 112 and rotatably connected to the first connecting section 112 , and the NFC antenna 4 is sleeved on the second connecting section 113 .

[0069] By sleeve-mounting the rotating seat 12 on the first connecting section 112 and the NFC antenna 4 on the second connecting section 113 , the external space of the rotary potentiometer 1 can be fully utilized, the compactness of the layout of the mechanical button 100 is improved, and the miniaturization design of the mechanical button 100 is further facilitated.

[0070] Optionally, the knob circuit board 3 is electrically connected to the main board 6 .

[0071] For example, the knob circuit board 3 is electrically connected to the main board 6 via the first connector 30. The first connector 30 may be a 6-pin connector.

[0072] Optionally, the key panel 9 is bonded to the key bracket 8 via adhesive 91 .

[0073] For example, the key panel 9 is bonded to the end surface of the key bracket 8 facing away from the main board 6 .

[0074] Alternatively, if Figure 5 and Fig.10 As shown, the knob 2 includes a first ring body 21 and a second ring body 22. The second ring body 22 is sleeved on the first ring body 21, and at least a portion of the second ring body 22 protrudes out of the first ring body 21 in a direction away from the main board 6. The first ring body 21 is sleeved on the rotating seat 12 and connected to the rotating seat 12. Figure 3 and Fig. 9 As shown, the button bracket 8 includes a pressing section 81 and a force transmission section 82.

The button panel 9 is connected to one end of the pressing section 81 facing away from the force transmission section 82.

[0075] By setting the knob 2 to include a first ring body 21 and a second ring body 22, and designing the first ring body 21 and the second ring body 22 as described above, not only the outer diameter of the second ring body 22 is made larger, which is convenient for users to identify and rotate the knob 2, but also the pressing area of ​​the button panel 9 is made larger, which is beneficial to improving the user's feel when pressing the button component, and thus helps to improve the user experience.

[0076] In addition, the pressing section 81 is disposed in the second ring body 22 , which can further improve the compactness of the mechanical key 100 and facilitate the miniaturization design of the mechanical key 100 .

[0077] Optionally, the key assembly further includes a pressing block 83, which is disposed at one end of the force transmission section 82 away from the pressing section 81 and connected to the force transmission section 82.

Another portion of the rotary potentiometer 1 and the knob 2 are all arranged outside the first width section 104 and corresponding to the first width section 104. The width direction is Figure 1 and Figure 8 The K direction is consistent.

[0079] For example, Figure 1As shown, a portion of the first width segment 104 is protruded out of the second width segment 105 , so that the width of the first width segment 104 is greater than the width of the second width segment 105 .

[0080] Among them, the overall structure composed of the knob assembly, the knob circuit board 3 and the NFC antenna 4 is relatively complex, and the overall space occupied is relatively large. By setting the housing 10 to include the first width section 104 and the second width section 105, and arranging the knob assembly, the knob circuit board 3 and the NFC antenna 4 in the first width section 104 with a larger width, the layout and installation of the knob assembly, the knob circuit board 3 and the NFC antenna 4 can be realized when the size of other parts of the housing 10 is relatively small. This is conducive to reducing the overall volume of the mechanical button 100 and reducing the space occupied by the mechanical button 100.

[0081] Optionally, a second width segment 105 is provided on both sides of the length direction of the first width segment 104. Figure 1 and Figure 8 The C direction.

[0085] The front shell 101 and the rear shell 102 may be connected via a third screw 503 .

[0086] By setting the shell 10 to include a front shell 101 and a rear shell 102, the rotary potentiometer 1, the knob circuit board 3, the NFC antenna 4, the NFC bracket 5, etc. can be installed in the rear shell 102 first, and then the front shell 101 is connected to the rear shell 102, thereby facilitating the assembly of the mechanical button 100.

[0087] Optionally, the mainboard 6 and the rear housing 102 may be connected via a fourth screw 504 .
