Description

[Technical Field]

[0001] The present invention relates to a scroll wheel device, and more particularly to a scroll wheel device installed on a keyboard that can simulate sound and vibration. [Background technology]

[0002] 1, a keyboard device 1 includes a keyboard body 11, a scroll wheel module 12 mounted on the keyboard body 11, and a lever module 13 mounted on the keyboard body 11. The scroll wheel module 12 is provided so that a user can rotate it, thereby providing scroll wheel control for a computer. Summary of the Invention [Problem to be solved by the invention]

[0003] Although the prior art key board device 1 is already equipped with a scroll wheel module 12, the scroll wheel module 12 still has the following drawbacks in actual use.

[0004] First, they cannot make sounds.

[0005] A ratchet structure can be installed inside the early scroll wheel module 12, which can limit the rotation angle of the scroll wheel of the scroll wheel module 12 and can generate a sound when the scroll wheel rotates. If the ratchet structure is removed from the scroll wheel module 12, the scroll wheel module 12 cannot generate a sound, and therefore the sound generated by the ratchet structure cannot be simulated.

[0006] Second, it is not possible to generate vibrations.

[0007] To summarize the above, the ratchet structure can limit the rotation angle of the scroll wheel of the scroll wheel module 12, and the ratchet structure can generate vibrations when the scroll wheel rotates. If the ratchet structure is removed from the scroll wheel module 12, the scroll wheel module 12 cannot generate vibrations, and therefore the vibrations generated by the ratchet structure cannot be simulated.

[0008] Third, it cannot sense touch movements.

[0009] A typical scroll wheel module 12 does not have a touch sensing module and cannot sense the touch of a human finger on the scroll wheel module 12. Therefore, the early scroll wheel module 12 installed in the keyboard device 1 can only sense the rotation angle of the scroll wheel and cannot perform more operations on the computer.

[0010] Therefore, how to make the scroll wheel module 12 generate sound, generate vibration, and also sense the touch action of a human fingertip is an urgent goal that relevant engineers should strive for. [Means for solving the problem]

[0011] In view of this, the object of the present invention is to provide a scroll wheel device installed on a keyboard, the scroll wheel device installed on the keyboard is installed on a keyboard body, and the scroll wheel device installed on the keyboard includes a scroll wheel unit.

[0012] The scroll wheel unit includes a scroll wheel base installed on the keyboard body, a scroll wheel body installed on the scroll wheel base, a rotation sensing module installed on the scroll wheel base, a sound simulation module electrically connected to the rotation sensing module, and a vibration simulation module electrically connected to the rotation sensing module, wherein the rotation sensing module senses a rotation angle of the scroll wheel body relative to the scroll wheel base, the sound simulation module generates a sound according to the rotation angle of the scroll wheel body, and the vibration simulation module generates a vibration according to the rotation angle of the scroll wheel body.

[0013] In one embodiment, the scroll wheel device installed on the keyboard further includes a base unit, the base unit including a circuit board module installed on the keyboard body, and the scroll wheel base installed on the circuit board module.

[0014] In one embodiment, the base unit further includes a fixed shell installed on the keyboard body and a shell opening installed on the fixed shell, the scroll wheel unit is received in the fixed shell, and the scroll wheel body is exposed to the outside through the shell opening.

[0015] In one embodiment, the sound simulation module is mounted on the circuit board module.

[0016] In one embodiment, the scroll wheel unit further includes a touch electrode installed at an end of the scroll wheel body, an induction electrode installed at a distance from the touch electrode, and a touch sensing module electrically connected to the induction electrode.

[0017] In one embodiment, the scroll wheel unit further includes a freewheel driving module electrically connected to the rotation sensing module and the touch sensing module, and when the rotation sensing module senses a rotation of the scroll wheel body, the freewheel driving module continuously transmits a rotation signal, and when the touch sensing module senses a touch on the touch electrode, the freewheel driving module stops transmitting the rotation signal.

[0018] In one embodiment, the outer surface of the touch electrode has a toothed structure.

[0019] In one embodiment, the scroll wheel unit further includes a receiving part mounted on the scroll wheel base, and the vibration simulation module is mounted on the receiving part.

DETAILED DESCRIPTION OF THE INVENTION

[0024] The features and technical contents of the patent application related to the present invention are clearly shown in the detailed description coupled with one embodiment in the reference drawings.

[0025] Referring to FIG. 2, there is shown an embodiment of a keyboard-mounted scroll wheel device of the present invention, in which the keyboard-mounted scroll wheel device is mounted on a keyboard body 11, and the keyboard-mounted scroll wheel device includes a base unit 3 and a scroll wheel unit 4.

[0026] Referring to FIG. 3, the base unit 3 includes a circuit board module 31 installed on the keyboard body 11, a fixed shell 32 installed on the keyboard body 11, a shell opening 33 installed on the fixed shell 32, and a scroll wheel fixed frame 34 installed on the fixed shell 32.

[0027] 4, 5, 7, and 8, the scroll wheel unit 4 includes a scroll wheel base 401 installed on the keyboard body 11, a scroll wheel body 402 installed on the scroll wheel base 401, a rotation sensing module 403 installed on the scroll wheel base 401, a sound simulation module 404 electrically connected to the rotation sensing module 403, a vibration simulation module 405 electrically connected to the rotation sensing module 403, a touch electrode 411 installed on an end of the scroll wheel body 402, an induction electrode 412 installed at a distance from the touch electrode 411, a touch sensing module 413 electrically connected to the induction electrode 412, a freewheel driving module 421 electrically connected to the rotation sensing module 403 and the touch sensing module 413, a receiving portion 422 installed on the scroll wheel base 401, and a magnetic rotation shaft 423 installed on the rotation shaft of the scroll wheel body 402.

[0028] 3 , in the above embodiment, the scroll wheel base 401 is installed on the circuit board module 31, but is not limited thereto. The circuit board module 31 is one of the circuit boards in the keyboard body 11, the circuit board module 31 is fixed to the keyboard body 11, the scroll wheel base 401 is fixed to the circuit board module 31, the fixed shell 32 is fixed to the circuit board module 31, the scroll wheel unit 4 is received in the fixed shell 32, and the scroll wheel fixing frame 34 is located in the shell opening 33 and covers part of the shell opening 33. In this embodiment, there are two scroll wheel fixing frames 34, one on each side of the scroll wheel unit 4, which fix the scroll wheel unit 4 in the shell opening 33 of the fixed shell 32. The receiving groove of the scroll wheel base 401 extends left and right to accommodate a long scroll wheel body 402 and touch electrodes 411. In actual implementation, the scroll wheel fixing frames 34 may not be installed, and the scroll wheel body 402 and the touch electrodes 411 may also be designed with different lengths, so this is not limited to this. In some embodiments, the lengths of the scroll wheel body 402, the touch electrodes 411, and the magnetic rotation shaft 423 are the same as those of the two scroll wheel fixing frames 34 and are installed in the shell opening 33 of the fixed shell 32. Here, the scroll wheel body 402 and the touch electrode 411 are exposed to the outside through the shell opening 33 and are provided to be in contact with a human finger 21, and when a user touches the touch electrode 411, a force is applied thereto to control the rotation of the scroll wheel body 402 relative to the scroll wheel base 401.

[0029] 6, the magnetic rotation shaft 423 is disposed at the rotation axis of the scroll wheel body 402, and the scroll wheel body 402 rotates the magnetic rotation shaft 423, which rotates synchronously with the scroll wheel body 402. The magnetic rotation shaft 423 is a bipolar magnet with diametric magnetization. Referring to FIG. 8, in this embodiment, a side circuit board 433 is disposed on the scroll wheel base 401, and the rotation sensing module 403 is disposed on the side circuit board 433. The rotation sensing module 403 and the magnetic rotation shaft 423 are spaced apart, and the south and north poles of the magnetic rotation shaft 423 all face the rotation sensing module 403. The rotation sensing module 403 senses changes in magnetism as the magnetic rotation shaft rotates, and thus senses the rotation angle of the scroll wheel body 402 relative to the scroll wheel base 401. In some embodiments, the rotation sensing module 403 uses Hall effect magnetic induction sensing technology, but in actual implementation, the rotation sensing module 403 can also use other rotation sensing technologies, and is not limited thereto.

[0030] 3 and 5, in the above embodiment, the sound simulation module 404 is installed on the circuit board module 31, and the sound generated by the sound simulation module 404 can be exposed to the outside from the keyboard body 11. In actual implementation, the sound simulation module 404 may be installed at other locations, and is not limited thereto. The sound simulation module 404 is a control circuit equipped with a speaker, and the sound simulation module 404 can store and emit sounds to the outside. The sound simulation module 404 generates sounds according to the rotation angle of the scroll wheel body 402. For example, when the scroll wheel body 402 is rotated 5 degrees, the sound simulation module 404 generates a "click" sound to the outside, but is not limited thereto.

[0031] 4, 5, and 6, the vibration simulation module 405 generates vibrations according to the rotation angle of the scroll wheel body 402, and the vibration simulation module 405 is a vibration motor installed in the receiving part 422. For example, when the scroll wheel body 402 rotates 5 degrees, the sound simulation module 404 generates a tapping vibration, but this is not limiting. The receiving part 422 is a recessed structure installed in the scroll wheel base 401, and the vibration simulation module 405 is installed in the receiving part 422. When the vibration simulation module 405 generates vibrations, the vibration force is transmitted through the scroll wheel base 401, the scroll wheel body 402, and the touch electrode 411, so that the human finger 21 in contact with the touch electrode 411 feels the vibrations.

[0032] 6, the scroll wheel body 402 is circular, and in the embodiment, the scroll wheel body 402 is composed of, but not limited to, small and large balls. The touch electrode 411 is a circular metal plate, and covers the outer periphery of the scroll wheel body 402. The outer surface of the touch electrode 411 has, but is not limited to, a toothed structure. In actual implementation, a plastic sleeve may be provided on the outer surface of the touch electrode 411, but is not limited to this.

[0033] 7 , in the above embodiment, when the human finger 21 touches the top end of the touch electrode 411, a charge is generated at the top end of the touch electrode 411, and an opposite charge may be generated at the bottom of the touch electrode 411. The induction electrode 412, which is spaced apart from the touch electrode 411, is adjacent to the bottom of the touch electrode 411, and an opposite charge may be generated at the induction electrode 412 compared to the bottom of the touch electrode 411. The touch sensing module 413 detects a change in the charge of the induction electrode 412, thereby detecting that the human finger 21 touches the touch electrode 411. In actual implementation, the scroll wheel unit 4 may use other touch sensing technologies, and is not limited thereto.

[0034] Referring to FIG. 5 , the freewheel driving module 421 and the touch sensing module 413 can be combined to provide a freewheel control mode to control a computer. For example, when a computer displays a web browser screen and the freewheel driving module 421 is set to an active state, and the rotation sensing module 403 detects the rotation of the scroll wheel body 402, the freewheel driving module 421 continuously transmits a rotation signal, allowing the computer to continue scrolling the web browser. Even if the scroll wheel body 402 stops rotating, the freewheel driving module 421 can still continuously transmit a rotation signal, allowing the computer to continue scrolling the web browser. When the touch sensing module 413 detects a touch on the touch electrode 411, the freewheel driving module 421 can transmit a rotation stop signal, allowing the computer to stop scrolling the web browser. In actual implementation, the freewheel driving module 421 can also perform other computer controls, but is not limited to these. When the freewheel driving module 421 is off, the scroll wheel device installed on the keyboard controls the computer in the manner of a typical scroll wheel.

[0035] As can be seen from the above description, the scroll wheel device installed on the keyboard of the present invention certainly has the following advantages:

[0036] First, it can produce sound.

[0037] The sound simulation module 404 is installed on the circuit board module 31, and the sound generated by the sound simulation module 404 can be exposed to the outside from the keyboard body 11. The sound simulation module 404 generates a sound according to the rotation angle of the scroll wheel body 402, and can simulate a sound when a ratchet structure is operating even if the scroll wheel device installed on the keyboard does not have a ratchet structure.

[0038] Second, vibrations can be generated.

[0039] The vibration simulation module 405 generates vibrations according to the rotation angle of the scroll wheel body 402. When the vibration simulation module 405 generates vibrations, the vibrating force is transmitted to the outside via the scroll wheel base 401, the scroll wheel body 402, and the touch electrode 411, so that a human finger 21 touching the touch electrode 411 can feel the vibrations, and the human finger 21 can grasp the rotation angle of the scroll wheel body 402 from the vibrations.

[0040] Third, it can sense touch actions.

[0041] The touch electrode 411, the induction electrode 412 and the touch sensing module 413 are combined with each other to sense the change in charge on the rotating scroll wheel body 402, thereby obtaining the touch action of the human finger 21, and further driving the freewheel driving module 421 to provide a freewheel control mode and control a computer.

[0042] To sum up, the scroll wheel device installed on the keyboard not only provides basic scroll wheel operation, but also the sound simulation module 404 and the vibration simulation module 405 can simulate the sound and vibration generated when the ratchet structure operates. The touch sensing module 413 can sense the charge change of the touch electrode 411 through the induction electrode 412, thereby detecting the touch of the human finger 21 on the touch electrode 411. The freewheel driving module 421 can implement a freewheel control mode during operation, thereby reliably achieving the objectives of the present invention.
