Abstract
Description
Technical Field
[0001] The utility model relates to an input device, in particular to an input device with a switch structure provided with keys, a rotary disk and a rocker. Background Art
[0002] A computer is a system that can process a large amount of information and can be applied to various fields. The keyboard is one of the input interfaces of the computer for inputting data into the computer. A plurality of keys are arranged on the keyboard. When a user presses any key, a corresponding electrical signal will be generated and transmitted to the controller through a circuit to execute the corresponding function.
[0003] Generally, the keys arranged on a keyboard are contact keys. When a key is pressed, two electrodes will be forced to contact to emit an electrical signal externally. However, the above-mentioned contact keys can only detect the signal of one moving position when the electrodes are in contact. In addition, when the two electrodes are in contact, friction will be generated, and there is a problem of service life.
[0004] It can be seen from the above description that the existing keyboard has the following disadvantages when in use:
[0005] I. It cannot detect the pressing stroke:
[0006] In a general contact key structure, the electrodes are arranged below the pressing body and spaced apart by a certain distance. When the pressing body is pressed out by a certain distance, the electrodes will be triggered and emit a signal externally. However, the pressing stroke of the pressing body when it does not contact the electrodes cannot be detected.
[0007] II. There is a problem of frictional loss:
[0008] For the contact electrodes in the key structure, two electrodes must be used and the two electrodes must be in contact with each other. From the open circuit state to the short circuit state, the controller can obtain the electrical signal and emit the pressing information externally. However, when the two electrodes are in contact, not only will there be contact friction, but also current will be generated, which will cause loss to the surfaces of the electrodes and there will be a problem of service life.
[0009] III. It cannot change to other input modes:
[0010] Although in the market, various styles such as black axis, white axis, blue axis, red axis, and brown axis are changed from the general key structure, generally the keys are of the pressing key structure and can only detect the pressing action of the user. Therefore, the general keyboard cannot detect actions other than pressing. Summary of the Utility Model

In actual implementation, the number of the setting holes 312 may be one, and the induction module 321 may also be provided on the circuit module 313, which should not be limited thereto.
[0074] Review Figure 1 , Figure 2 , and Figure 3 , the induction module 321 detects the movement of the control body 322 and outputs the detection result externally.

[0076] The control housing 323 is provided in the setting hole 312 and is tightly fitted with the setting hole 312. In some embodiments, the side wall structure of the control housing 323 is designed to be the same as that of the existing MX switch. Therefore, the control unit 32 can be installed in the setting hole 312 where the existing MX switch can be installed. In actual implementation, the control housing 323 and the setting hole 312 can also form other structures, which should not be limited thereto.
[0077] The stopper 324 is provided on the side of the control housing 323. When the control housing 323 is provided in the setting hole 312, the stopper 324 abuts against the side of the bottom housing 311, which can prevent the control housing 323 from falling off the bottom housing 311.
[0078] Refer to Figure 3 , the structure of the operation body 322 is selected from one of a button, a rotary disk, a rocker or a combination thereof.

In actual implementation, the key caps 51, knobs 52, and covers 53 provided on the operation body 322 may also form other structures, and should not be limited thereto. Since the operation shells 323 of the button, the rotary disk, and the rocker all use the same structure, their positions can be interchanged, and the user can adjust the positions by himself.
[0079] Please refer to Figure 3 , and Figure 4 , the structure of the operation body 322 is a button. Please refer to Figure 3 , and Figure 5 , the structure of the operation body 322 is a rotary disk. Please refer to Figure 3 , and Figure 6 , the structure of the operation body 322 is a rocker. In actual implementation, the structure of the operation body 322 may be a combination of a button and a rotary disk, or a combination of a button and a rocker, or a combination of a rotary disk and a rocker, or a combination of a button, a rotary disk and a rocker, and should not be limited thereto.
[0080] With reference to Figure 7 , the control unit 32 further includes a plurality of first contact electrodes 325 provided at the bottom of the control housing 323, a plurality of second contact electrodes 326 provided at the bottom of the control housing 323, and a positioning body 327 provided at the bottom of the control housing 323. The first contact electrode 325 and the second contact electrode 326 are respectively disposed on both sides of the positioning body 327, and the first contact electrode 325 and the second contact electrode 326 are connected to the circuit module 313. In actual implementation, a plurality of positioning bodies 327 may also be provided, and should not be limited thereto. Among them, since the first contact electrode 325 and the second contact electrode 326 are respectively disposed on both sides of the positioning body 327, the control unit 32 can only be inserted into the setting hole 312 of the base unit 31 in one direction, and the control unit 32 cannot be rotated on the base unit 31 or set in other ways.
[0081] The circuit module 313 is a printed circuit board assembly (PCBA) disposed in the bottom housing 311. In the first embodiment, the positioning body 327 is disposed in the middle of the bottom of the control housing 323 and penetrates through the circuit module 313 to fix the control housing 323 on the circuit module 313. The plurality of first contact electrodes 325 are metal electrodes of an existing MX switch. The number of the plurality of second contact electrodes 326 can be eight and arranged in two rows, or can also be four and arranged in one row.
[0082] In the first embodiment, the plurality of first contact electrodes 325 and the plurality of second contact electrodes 326 are electrically connected to the sensing module 321. The plurality of first contact electrodes 325 and the plurality of second contact electrodes 326 can use fixed pins to be fixed on the circuit module 313 and are electrically connected to the transmission control module 331 and the computer control module 332. In some embodiments, the transmission control module 331 is also provided with fixed pins (not shown in the figure) or elastic pins (not shown in the figure) to be electrically connected to the plurality of first contact electrodes 325 and the plurality of second contact electrodes 326. In actual implementation, the plurality of first contact electrodes 325 and the plurality of second contact electrodes 326 can also use pogo pins, and this should not be taken as a limitation.
[0083] A plurality of contact electrodes (not shown in the figure) are disposed on the circuit module 313. In the first embodiment, the plurality of contact electrodes disposed on the circuit module 313 are via electrodes. The plurality of first contact electrodes 325 and the plurality of second contact electrodes 326 can penetrate through the plurality of fixed pins to form an electrical connection of fixed-pin socket contact. The fixed pins can be welded to the circuit module 313 or can contact the electrodes or sockets on the circuit module 313. In actual implementation, the plurality of contact electrodes can also be configured as sockets, electrode plates, or other electrode structures, and this should not be taken as a limitation. Among them, contact electrodes can be disposed on the circuit module 313 for each first contact electrode 325 and each second contact electrode 326. The control unit 32 only needs to dispose the plurality of first contact electrodes 325 or the plurality of second contact electrodes 326 at the required positions, and can even completely not dispose the second contact electrodes 326. When the plurality of first contact electrodes 325 and the plurality of second contact electrodes 326 use pogo pins, the plurality of contact electrodes disposed on the circuit module 313 can be electrode plates to form an electrical connection of pogo-pin touch contact.
[0084] Since the side wall structure of the control housing 323 is designed to be the same as that of the existing MX switch, the control units 32 with the button control body 322, the control units 32 with the rotary control body 322, and the control units 32 with the rocker control body 322 can all be arranged in the same setting hole 312, and the plurality of first contact electrodes 325 and the plurality of second contact electrodes 326 can be detachably in contact with the circuit module 313. The user can replace the required control unit 32 according to the needs, achieving a keyboard with hot-swappable input keys.
[0085] The control body 322 and the sensing module 321 are spaced apart from each other. In the first embodiment, a magnet 3221 is arranged in the control body 322, and the sensing module 321 is arranged in the control housing 323. The sensing module 321 is a magnetic sensing circuit for detecting the magnetism of the magnet 3221. The sensing module 321 can use a Hall sensing circuit, a tunnel magnetoresistance (TMR) sensing circuit, or other sensing circuits. In actual implementation, the sensing module 321 is selected from one or a combination of a magnetic sensing circuit, an optical sensing circuit, an inductive sensing circuit, a capacitive sensing circuit, a force change sensing circuit, a radio frequency identification sensing circuit, a near field communication sensing circuit, a triboelectric nanogenerator sensing circuit, or other non-contact sensing circuits, and should not be limited thereto. The optical sensing circuit can use a light source and a light sensor. In the force change sensing circuit, the downward pressure change of the controller can be detected by one or more sensors.
[0086] Please refer to Figure 2 、 Figure 4 ,and Figure 8 ., a magnet 3221 is arranged at the bottom of the control body 322 with a button structure. The control body 322 can move up and down relative to the control housing 323. Therefore, the magnet 3221 at the bottom of the control body 322 is axially arranged for the sensing module 321 to detect the movement. Even a slight up and down movement of the control body 322 will change the magnetism in the space, and the sensing module 321 can detect it and further detect the movement stroke of the control body 322.
[0087] Please refer to Figure 2 、 Figure 5 ,and Figure 9 ., a magnet 3221 is arranged at the bottom of the control body 322 with a rotary structure. The control body 322 can rotate relative to the control housing 323. Therefore, the magnet 3221 at the bottom of the control body 322 is radially arranged for the sensing module 321 to detect the movement. Even a slight rotation of the control body 322 will change the magnetism in the space, and the sensing module 321 can detect it and further detect the rotation stroke of the control body 322.
[0088] Please refer to Figure 2 、 Figure 6 and Figure 10 , a magnet 3221 is provided at the bottom of the control body 322 having a rocker structure. The control body 322 can perform a rocker motion relative to the control housing 323. Therefore, the magnet 3221 at the bottom of the control body 322 is axially arranged for the sensing module 321 to detect the motion. Even a slight swing of the control body 322 will change the magnetism in the space, and the sensing module 321 can detect it and further detect the swing stroke of the control body 322.
[0089] In addition, for the combinations of a button and a dial, a button and a rocker, a dial and a rocker, and a button, a dial and a rocker, the magnet 3221 provided at the bottom of the formed control body 322 is radially arranged. The S pole and N pole of the axially arranged magnet 3221 have an up-and-down relationship, that is, a near-and-far relationship, with the sensing module 321. The S pole and N pole of the radially arranged magnet 3221 have a left-and-right relationship with the sensing module 321.
[0090] Among them, for the sensing module 321 of the control body 322 corresponding to the button structure, the data calculation technology is a linear algorithm. For the sensing module 321 of the control body 322 corresponding to the dial structure, the data calculation technology is a rotation algorithm (sine / cosine). For the sensing module 321 of the control body 322 corresponding to the rocker structure, the data calculation technology is a spherical algorithm. For the sensing module 321 of the control body 322 corresponding to the combination of a button structure and a dial structure, the data calculation technology is a linear algorithm plus a rotation algorithm. For the sensing module 321 of the control body 322 corresponding to the combination of a dial structure and a cross direction key (D-pad), the data calculation technology is a spherical algorithm plus a state algorithm. For the sensing module 321 of the control body 322 corresponding to the combination of a dial structure and a rocker structure, the data calculation technology is a neural network algorithm.

The computer device 211 can control the color light-emitting diodes and the color display panel, and can transmit data with the transmission control module 331. The plurality of control units 32 can transmit data, control directions, control volume, treble, bass, or other linear controls.
[0092] Refer to Figure 11, the transmission control module 331 has a touch screen disposed on the upper surface of the bottom housing 311. The transmission control module 331 can control the color light-emitting diodes and the color display panel, and can display data and touch and input data.
[0093] In addition, a first region 341, a second region 342, a third region 343, a fourth region 344, and a fifth region 345 can be defined on the upper surface of the bottom housing 311. Among them, a control unit 32 for buttons and / or a rotary dial can be provided in the first region 341 and the third region 343, and a control unit 32 for a joystick and / or a cross key can be provided in the fifth region 345.

In actual implementation, for the transmission control module 331, various control units 32 can be customarily arranged on the bottom housing 311, and should not be limited to the examples of this embodiment.
[0094] Refer to Figure 12 , which is a second embodiment of an input device 3 with a switch structure according to the present invention. This second embodiment is substantially the same as the first embodiment, and the same parts will not be described in detail here. The difference is that the base unit 31 further includes a plurality of bottom light-emitting modules 314 disposed at the bottom of the bottom housing 311, and a plurality of bottom light guides 315 disposed at the bottom of the bottom housing 311. In actual implementation, the number of the bottom light-emitting modules 314 and the bottom light guides 315 can be one.
[0095] In some embodiments, the bottom light-emitting module 314 is a color light-emitting diode disposed on the circuit module 313. The bottom of the bottom light guide 315 is aligned with the bottom light-emitting module 314. The bottom light guide 315 is disposed at the bottom of the control body 322, and the top of the bottom light guide 315 is aligned with the bottom and the periphery of the control body 322 to irradiate the light emitted by the bottom light-emitting module 314 upward from the periphery of the control body 322. Among them, the bottom light guide 315 can surround the control housing 323 or can be disposed on one side of the control housing 323.
[0096] The transmission control module 331 and the computer control module 332 can set the lighting effects of the bottom light-emitting module 314. The bottom light-emitting module 314 can indicate the position of the control body 322 and can also output various gorgeous lighting effects.
[0097] Refer to Figure 13, which is a third embodiment of an input device 3 with a switch structure of the utility model. The third embodiment is substantially the same as the first embodiment, and the similarities are not described in detail here. The difference is that the control unit 32 further includes a control light emitting module 328 arranged on the bottom shell 311, and a control light guide 329 arranged on the control body 322, and the control light emitting module 328 is arranged on the circuit module 313 inside the bottom shell 311.
[0098] Among them, the control light guide 329 extends from the bottom of the control body 322 to the top of the control body 322, and extends on the upper surface of the control body 322. The bottom of the control light guide 329 is aligned with the control light module 328. The control light guide 329 can guide the light emitted by the control light module 328 to the top of the control body 322, so that the top of the control body 322 can emit light outward.
[0099] The control light module 328 can transmit data with the transmission control module 331 and the computer control module 332. The transmission control module 331 and the computer control module 332 can set the lighting effect of the control light module 328. The control light module 328 can point out the position of the control body 322 and can also output various gorgeous lighting effects.
[0100] From the above description, it can be seen that the input device 3 with a switch structure of the present invention has the following functions:
[0101] 1. The range of motion detection:
[0102] A magnet 3221 is provided at the bottom of the control body 322 . No matter it is a button, a turntable, or a joystick, the slightest movement of the control body 322 will cause the magnetism in the space to change, and the sensing module 321 can detect it and further detect the moving stroke, rotating stroke, and swinging stroke of the control body 322 .
[0103] 2. Avoid friction loss:
[0104] The control body 322 and the sensing module 321 are spaced apart from each other. The sensing module 321 uses a non-contact sensing circuit. No friction loss is generated between the sensing module 321 and the control body 322, thereby effectively avoiding damage caused by loss.
[0105] 3. Provide input with multiple functions:
[0106] The plurality of first contact electrodes 325 and the plurality of second contact electrodes 326 are separably in contact with the circuit module 313, and the structure of the control body 322 is selected from one or a combination of a button, a rotary dial, and a rocker. A user can replace the required control unit 32 according to needs, achieving a keyboard with a hot-swappable input button.
[0107] In summary, the structure of the control body 322 is selected from one or a combination of a button, a rotary dial, and a rocker, so that the input device 3 with a switch structure has multiple input modes. The plurality of first contact electrodes 325 and the plurality of second contact electrodes 326 are separably in contact with the circuit module 313, having a hot-swappable function. The sensing module 321 uses a non-contact sensing circuit, and there is no frictional loss between the sensing module 321 and the control body 322.
