[0041] The following is combined with Figure 1~ Figure 2 The utility model is further described in detail, but it is not intended to limit the utility model.

[0042] A separate inductive sensing component comprises a key module 1 and a functional sensing module 2 arranged at the bottom of the key module 1, wherein the key module 1 is connected to the functional sensing module 2;

[0043] The key module 1 is provided with a metal piece 11, which is fixedly connected to the key module 1. The metal piece 11 is driven to move up and down by pressing the key module 1.

[0044] The function sensing module 2 includes a PCB board 21 and a sensing element 22 disposed on the PCB board 21 . The sensing element 22 is disposed corresponding to the metal element 11 . The metal element 11 moves away from or close to the sensing element 22 by pressing the key module 1 .

[0045] Specifically, the present application adopts a new signal triggering method. In the past, buttons usually generate signals through contact. In the present application, after the sensor 22 is energized, it generates a fixed inductance. Then, the button module 1 is pressed, and the button module 1 moves to drive the metal part 11 to move up and down. When the metal part 11 approaches the sensor 22, the inductance of the sensor 22 will change. The PCB board 21 captures the changed inductance and converts the state into a communication connected signal. When the metal part 11 is away from the sensor 22, the inductance returns to the initial state. The PCB board 21 captures the change in inductance again and converts the state into a communication disconnected signal. The signal conversion is achieved by the above, and the metal part 11 is not in contact with the sensor 22, and no friction consumption is generated, thereby extending the service life of the button. At the same time, even if dust or liquid is placed between the sensor 22 and the metal part 11, it will not affect the metal part 11 from changing the inductance of the sensor 22, thereby improving the stability of the button and preventing the occurrence of disconnection.

[0046] In some embodiments, the sensing element 22 is disposed on the upper surface of the PCB board 21;

[0047] Or the induction element 22 is disposed on the lower surface of the PCB board 21;

[0048] Alternatively, the sensing element 22 is respectively disposed on the upper surface and the lower surface of the PCB board 21 .

[0049] Specifically, in this embodiment, the sensing member 22 is disposed on the lower surface of the PCB board 21. The sensing member 22 is disposed on the lower surface of the PCB board 21 so that the distance between the sensing member 22 and the metal member 11 is increased, thereby increasing the pressing stroke of the key module 1. The increased stroke gradually releases the pressing force during the transmission process, thereby making the hand feel softer.

[0050] In other embodiments, the sensing member 22 is disposed on the upper surface of the PCB board 21. The sensing member 22 is disposed on the upper side of the PCB board 21 so as to shorten the distance between the metal member 11 and the sensing member 22, thereby shortening the pressing stroke of the key module 1. The shortened stroke allows the pressing force to be fully transmitted to the PCB board 21, and the feedback is stronger and faster, thereby improving the feedback of the key.

[0051] In other embodiments, the sensing member 22 is respectively arranged on the upper and lower surfaces of the PCB board 21, so that the sensing area of ​​the sensing member 22 is increased, thereby satisfying some functions that require a long press of the button to be realized. The increase in the sensing area will cause some deviations due to the pressing force, causing the metal member 11 to float up and down in the sensing area of ​​the sensing member 22. The increase in the area of ​​the sensing zone will not affect the coordination between the sensing member 22 and the metal member 11 even if the metal member 11 floats up and down, thereby making it easier to realize the power storage operation.

[0052] In some embodiments, the induction elements 22 are distributed in a planar manner or are distributed in a winding manner in a height direction.

[0053] In this embodiment, the sensing element 22 is arranged in the height direction of the PCB board 21. The sensing element 22 is arranged along the height direction to increase the sensing range of the sensing element 22 in the height direction, and the sensing sensitivity is better.

[0054] In other embodiments, the sensing elements 22 are distributed in a planar manner. The sensing elements 22 arranged in this manner occupy a smaller space, thereby reducing the size of the overall component.

[0055] In this embodiment, a through hole 23 is provided on the PCB board 21 . The diameter of the through hole 23 is greater than the diameter of the metal component 11 . The induction component 22 is provided around the through hole 23 , and the through hole 23 is provided corresponding to the metal component 11 .

[0056] Specifically, when working, pressing the button module 1 drives the metal part 11 to move toward the through hole 23, and finally placed in the through hole 23. The through hole 23 is located at the center of the sensing part 22. When the metal part 11 is placed in the through hole 23, the metal part 11 is also placed in the center of the sensing part 22, so that the moving position of the metal part 11 is fixed, preventing the metal part 11 from being too close to or far away from the sensing part 22, causing other changes in the inductance of the sensing part 22, and further improving the consistency of the button.

[0057] In this embodiment, the key module 1 includes a shaft body 12 and a key cap 13, the shaft body 12 includes a sleeve 121 and a shaft core 122, a housing cavity 123 is provided in the sleeve 121, a first sliding portion 124 is provided in the housing cavity 123, the first sliding portion 124 is integrally provided with the sleeve 121, the first sliding portion 124 has a sliding cavity 126, the shaft core 122 has a second sliding portion 125, the metal member 11 is fixedly provided at the bottom of the second sliding portion 125, and the second sliding portion 125 is provided in the sliding cavity 1 26, one end of the first sliding portion 124 is placed in the accommodating cavity 123, the other end of the first sliding portion 124 protrudes from the shaft sleeve 121, the first sliding portion 124 protruding from the shaft sleeve 121 is placed in the through hole 23, the sliding cavity 126 passes through the PCB board 21, one end of the axis 122 protrudes from the shaft sleeve 121 and is connected to the keycap 13, an elastic member 127 is arranged between the axis 122 and the shaft sleeve 121, the upper surface of the elastic member 127 abuts against the axis 122, and the lower surface of the elastic member 127 abuts against the shaft sleeve 121.

[0058] Specifically, Figure 2 As shown, when working, the keycap 13 is pressed, and the keycap 13 transmits the pressure to the axis 122. The axis 122 is pressed downward in the sliding cavity 126 by the pressure, and at the same time drives the metal part 11 to move toward the through hole 23. After the metal part 11 moves to the sensing range of the sensor 22, the inductance of the sensor 22 changes, and the PCB board 21 records this situation and converts the state into a switch connection signal, so that pressing the key enables the computer to realize the corresponding function.

[0059] In this embodiment, the elastic member 127 is a buffer spring. The elasticity of the buffer spring is relatively stable. When the key is pressed, the consistency of the movement of the metal member 11 can be ensured, and the key cap 13 can be reset faster.

[0060] The second sliding part 125 slides in the sliding groove, and guides the first sliding part 124 through the sliding groove, so that the second sliding part 125 always moves in one direction, and the metal part 11 always moves into the through hole 23, thereby improving the consistency of key operation.

[0061] The protruding portion of the first sliding portion 124 is placed in the through hole 23 , and the protruding portion of the first sliding portion 124 is positioned through the through hole 23 , which can prevent fooling, and at the same time position the key module 1 , making installation easier.

[0062] like Figure 1a As shown, when the key module 1 is not subjected to pressure, the relationship between the metal member 11 and the PCB board 21 is that the metal member 11 is located on the upper side of the PCB board 21 and does not contact the PCB board 21;

[0063] like Figure 1bAs shown, the arrow indicates the moving direction of the metal part 11 when it is under pressure. When it is under pressure, the metal part 11 moves in the direction of the arrow, that is, the metal part 11 moves downward into the through hole 23, and the sensing part 22 senses the metal part 11, thereby generating a signal.

[0064] like Figure 1c As shown, after the pressing is completed, the metal part 11 gradually moves away from the PCB board 21, wherein the direction indicated by the arrow is the direction of movement of the metal part 11. After the pressing is completed, the metal part 11 is driven by the elastic part 127 to move in the direction of the arrow, thereby leaving the sensing range of the sensing part 22, thereby disconnecting the signal connection.

[0065] In this embodiment, the induction element 22 is an electric induction coil.

[0066] The structure of the inductor coil is relatively simple, and it is easy to manufacture and install. At the same time, the state of the inductor coil can be changed without contact between the inductor coil and the metal part 11.

[0067] In this embodiment, the metal part 11 is a magnet or a common metal part 11 .

[0068] In some embodiments, the metal part 11 can be a magnet or an ordinary metal part 11. As long as the metal part 11 can be sensed by the inductor coil, there is no need for excessive restrictions. This application does not limit the specific material of the metal part 11 and it can be set according to specific circumstances.

[0069] In this embodiment, the diameter of the through hole 23 is larger than the cross-sectional diameter of the metal member 11 .

[0070] Specifically, setting the diameter of the through hole 23 larger than the diameter of the cross-sectional area of ​​the metal component 11 allows the metal component 11 to be placed more easily in the through hole 23 , facilitates the sensing component 22 to sense the position of the metal component 11 , and prevents the through hole 23 from hindering the movement of the metal component 11 .

[0071] Embodiment 2

[0072] like Figure 3 As shown, this embodiment is different from the first embodiment in that the key module 1 includes a shaft body 12, an elastic member 127 and a keycap 13. The lower surface of the shaft body 12 abuts against the PCB board 21. The shaft body 12 has a accommodating cavity 123 inside. The elastic member 127 is arranged in the accommodating cavity 123 and the bottom of the elastic member 127 abuts against the PCB board. A part of the keycap 13 passes through the shaft body 12 and contacts the upper surface of the elastic member 127. The elastic member 127 has a deformation cavity 128 inside. The metal member 11 is arranged in the deformation cavity 128 and contacts with the elastic member 127. The elastic member 127 is a rubber structure.

[0073] Specifically, the shaft body 12 has openings on both the upper and lower sides. The upper opening of the shaft body 12 is used for connecting the keycap 13 with the elastic member 127 inside the shaft body 12. In the present application, the elastic member 127 is a rubber structure. When the keycap 13 applies downward pressure, it abuts against the elastic member 127, and the bottom of the elastic member 127 is deformed. The bottom of the elastic member 127 is separated to both sides, and the metal member 11 connected to the elastic member 127 moves downward into the through hole 23. The sensing member 22 senses the metal member 11, and the metal member 11 causes the inductance of the sensing member 22 to change. At this time, the PCB board 21 records and converts the state into a connected signal, thereby realizing the corresponding function. After the keycap 13 stops applying pressure, the bottom of the elastic member 127 gathers toward the middle, so that the elastic member 127 returns to its initial state. Due to the recovery of the state of the elastic member 127, the metal member 11 is driven to move upward and leave the sensing area of ​​the sensing member 22. The inductance of the sensing member 22 returns to its initial state, realizing the disconnection of the signal.

[0074] The working principle of this embodiment is the same as that of the first embodiment, except that the corresponding structures are slightly different.

[0075] Embodiment 3

[0076] like Figure 4 As shown, this embodiment is different from the second embodiment in that the key module 1 includes a sleeve 121, an elastic member 127 and a keycap 13, the lower surface of the sleeve 121 abuts against the PCB board 21, the sleeve 121 has a accommodating cavity 123 inside, the elastic member 127 is arranged in the accommodating cavity 123, the elastic member 127 is a buffer spring, the metal member 11 is connected to the keycap 13, the elastic member 127 is sleeved on the outside of the metal member 11, and the upper surface of the elastic member 127 abuts against the keycap 13, and the lower surface of the elastic member 127 abuts against the PCB board 21.

[0077] Specifically, this embodiment replaces the elastic member 127 in the second embodiment with a buffer spring. The buffer spring is sleeved on the metal member 11, and the upper surface of the elastic member 127 abuts the keycap 13, and the lower surface of the elastic member 127 abuts the PCB board 21. Different from the working principle of the second embodiment, the buffering effect in the second embodiment is achieved by the recovery effect of the rubber structure material itself, while the buffering effect in this embodiment is achieved by the rebound effect of the mechanical structure of the buffer spring. Compared with the second embodiment, the buffer spring has better rebound force and its elasticity is maintained longer.

[0078] The other structures are the same as those in the second embodiment and will not be described in detail in this embodiment.

[0079] Embodiment 4

[0080] like Figure 5As shown, the difference between this embodiment and the first embodiment is that a fixed middle plate 3 is arranged between the key module 1 and the function sensing module 2, and a through hole 31 is arranged on the fixed middle plate 3. The through hole 31 is arranged concentrically with the through hole 23, and the diameter of the through hole 31 is greater than or equal to the diameter of the through hole 23. The key module 1 includes an elastic member 127, a reset member 32 and a keycap 13. The upper surface of the elastic member 127 is connected to the keycap 13, and the interior of the elastic member 127 has a accommodating cavity 123. The metal member 11 is arranged in the accommodating cavity 123 and fixedly connected to the elastic member 127. Two reset members 32 are arranged, and the two reset members 32 are crossed and movably connected. The bottom of the reset member 32 is connected to the fixed middle plate 3, and the top of the reset member 32 contacts the keycap 13. The elastic member 127 is a rubber structure.

[0081] Specifically, in this embodiment, the shaft sleeve 121 and the shaft core 122 in the first embodiment are cancelled, and a fixed middle plate 3 and a reset member 32 are added. When the key cap 13 is pressed, the elastic member 127 and the buffer member jointly buffer the key cap 13, so that the pressing feel of the case is better. The function of the fixed middle plate 3 is to fix the reset member 32. The reset member 32 itself has a force to push the key cap 13 upward. When pressed, the key cap 13 transmits the pressure to the elastic member 127 and the reset member 32. The elastic member 127 is a rubber structure. The elastic member 127 is deformed by the pressure. The two sides of the bottom of the elastic member 127 expand outward, so that the metal member 11 connected to the elastic member 127 is pushed upward. The metal part 11 moves downward and falls into the through hole 23, and the two reset members 32 are pressed by the pressure, and the end of the reset member 32 away from the fixed middle plate 3 rotates around the end of the reset member 32 fixed to the fixed middle plate 3, and the end of the reset member 32 away from the fixed middle plate 3 slowly approaches the fixed middle plate 3, thereby achieving a buffering effect. After the pressure is applied, the two sides of the bottom of the elastic member 127 contract, and the elastic member 127 returns to its initial state to drive the metal part 11 to move upward, and the reset member 32 rotates around the end of the reset member 32 fixed to the fixed middle plate 3, so that the end of the reset member 32 away from the fixed middle plate 3 is further away from the fixed middle plate 3, thereby resetting the keycap 13 upward.

[0082] It should be noted that in this embodiment, the elastic member 127 is a rubber structure.

[0083] Specifically, a via hole 31 is provided on the fixed middle plate 3 , the via hole 31 corresponds to the through hole 23 , and the diameter of the via hole 31 is greater than or equal to the diameter of the through hole 23 , so as to prevent the via hole 31 from affecting the passability of the metal part 11 .

[0084] Embodiment 5

[0085] like Figure 6As shown, the difference between this embodiment and the fourth embodiment is that a fixed middle plate 3 is further arranged between the key module 1 and the function sensing module 2, and a through hole 31 is arranged on the fixed middle plate 3.
