Description

Technical Field

[0001] The utility model relates to a roller device, in particular to a roller device which can simulate sound and vibration and is arranged on a keyboard. Background Art

[0002] See also Figure 1 , is a keyboard device 1, which includes a keyboard body 11, a scroll wheel module 12 arranged on the keyboard body 11, and a lever module 13 arranged on the keyboard body 11. The scroll wheel module 12 can be rotated by the user to control the scroll wheel of the computer.

[0003] Although the conventional technology has provided a scroll wheel module 12 in the keyboard device 1, the scroll wheel module 12 still has the following disadvantages when actually used:

[0004] 1. Unable to make sound:

[0005] In the early stage, a ratchet structure is provided inside the roller module 12 to limit the rotation angle of the roller of the roller module 12. When the roller rotates, the ratchet structure produces a sound. If the ratchet structure is removed from the roller module 12, the roller module 12 will not produce a sound and cannot simulate the sound produced by the ratchet structure.

[0006] 2. Unable to generate vibration:

[0007] Continuing from the above, the ratchet structure can limit the rotation angle of the roller of the roller module 12, and when the roller rotates, the ratchet structure will generate vibration. If the ratchet structure is removed from the roller module 12, the roller module 12 will not generate vibration and cannot simulate the vibration generated by the ratchet structure.

[0008] 3. Unable to detect touch behavior:

[0009] The conventional scroll wheel module 12 does not have a touch detection module and cannot sense the human finger touching the scroll wheel module 12 . Therefore, the scroll wheel module 12 previously installed in the keyboard device 1 can only detect the rotation angle of the scroll wheel and cannot generate more control actions for the computer.

[0010] Therefore, how to make the scroll wheel module 12 emit sound and generate vibration, and also detect the touch behavior of human fingers, is a goal that relevant technical personnel urgently need to work hard on. Utility Model Content

[0011] In view of this, the purpose of the present invention is to solve at least one of the above problems and provide a roller device arranged on a keyboard, wherein the roller device arranged on the keyboard is arranged in a keyboard body, and the roller device arranged on the keyboard includes a roller unit.

[0012] The roller unit includes a roller base arranged in the keyboard body, a roller body arranged on the roller base, a rotation detection module arranged on the roller base, a sound simulation module electrically connected to the rotation detection module, and a vibration simulation module electrically connected to the rotation detection module. The rotation detection module detects the rotation angle of the roller body relative to the roller base, the sound simulation module emits sound according to the rotation angle of the roller body, and the vibration simulation module generates vibration according to the rotation angle of the roller body.

[0013] In one embodiment, the roller device disposed on the keyboard further includes a base unit. The base unit includes a circuit board module disposed in the keyboard body, and the roller base is disposed on the circuit board module.

[0014] In one embodiment, the base unit further includes a fixed shell disposed on the keyboard body, and a shell opening disposed on the fixed shell. The roller unit is accommodated in the fixed shell, and the roller body is exposed to the outside from the shell opening.

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

[0016] In one embodiment, the roller unit further includes a touch electrode disposed on the periphery of the roller body, a sensing electrode spaced apart from the touch electrode, and a touch detection module electrically connected to the sensing electrode.

[0017] In one embodiment, the roller unit further includes a freewheel drive module electrically connected to the rotation detection module and the touch detection module. When the rotation detection module detects that the roller body is rotating, the freewheel drive module continues to send a rotation signal. When the touch detection module detects that the touch electrode is touched, the freewheel drive module stops sending a rotation signal.

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

[0019] In one embodiment, the roller unit further includes a receiving portion disposed on the roller base, and the vibration simulation module is disposed in the receiving portion.

[0020] In one embodiment, the vibration simulation module is a vibration motor disposed in the accommodating portion.

[0021] In one embodiment, the roller unit further includes a magnetic shaft disposed on the roller body shaft, and the rotation detection module is spaced apart from the magnetic shaft.

[0022] The beneficial effect of the present invention is that, since the sound simulation module emits sound according to the rotation angle of the roller body, and the vibration simulation module generates vibration according to the rotation angle of the roller body, the sound simulation module and the vibration simulation module cooperate to simulate the sound and vibration generated by the movement of the early ratchet structure. The touch detection module can detect the touch behavior of a human finger through the sensing electrode and the touch electrode, so that the freewheel drive module can send a signal to the computer when the human finger touches.

[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0039] See also Figure 2 , is an embodiment of the present invention, a roller device disposed on a keyboard. The roller device disposed on the keyboard is disposed in a keyboard body 11 , and the roller device disposed on the keyboard includes a base unit 3 and a roller unit 4 .

[0040] Please refer to Figure 3 The base unit 3 includes a circuit board module 31 disposed in the keyboard body 11, a fixed shell 32 disposed on the keyboard body 11, a shell opening 33 disposed on the fixed shell 32, and a roller fixing frame 34 disposed on the fixed shell 32.

[0041] See also Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 The scroll wheel unit 4 includes a scroll wheel base 401 disposed in the keyboard body 11, a scroll wheel body 402 disposed on the scroll wheel base 401, a rotation detection module 403 disposed on the scroll wheel base 401, a sound simulation module 404 electrically connected to the rotation detection module 403, a vibration simulation module 405 electrically connected to the rotation detection module 403, a touch electrode 411 disposed on the periphery of the scroll wheel body 402, a sensing electrode 412 spaced apart from the touch electrode 411, a touch detection module 413 electrically connected to the sensing electrode 412, a freewheel driving module 421 electrically connected to the rotation detection module 403 and the touch detection module 413, an accommodating portion 422 disposed on the scroll wheel base 401, and a magnetic shaft 423 disposed on the rotation axis of the scroll wheel body 402.

[0042] See also Figure 3In this embodiment, the roller base 401 is disposed on the circuit board module 31, but the present invention 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 roller base 401 is fixed to the circuit board module 31. The fixed housing 32 is fixed to the circuit board module 31. The roller unit 4 is accommodated in the fixed housing 32. The roller fixing frame 34 is located in the housing opening 33 and partially covers the housing opening 33. In this embodiment, two roller mounts 34 are provided, one on each side of the roller unit 4, to secure the roller unit 4 within the housing opening 33 of the fixed housing 32. The accommodating grooves on the roller base 401 extend left and right to accommodate the longer roller body 402 and touch electrode 411. In actual implementation, the roller mounts 34 may not be provided, and the roller body 402 and touch electrode 411 may be designed to have other lengths, without limitation. In some embodiments, the lengths of the roller body 402, the touch electrode 411, and the magnetic shaft 423 match the lengths of the two roller mounts 34, allowing them to be disposed within the housing opening 33 of the fixed housing 32. The roller body 402 and the touch electrode 411 are exposed from the housing opening 33 to provide contact for the human finger 21 . When the user touches the touch electrode 411 , force can be applied thereto to control the roller body 402 to rotate relative to the roller base 401 .

[0043] See Figure 6 The magnetic shaft 423 is disposed at the rotation axis of the roller body 402. The roller body 402 drives the magnetic shaft 423 to rotate. The magnetic shaft 423 rotates synchronously with the roller body 402. The magnetic shaft 423 is a diameter-magnetized bipolar magnet. Figure 8 In the preferred embodiment, a side circuit board 433 is disposed on the roller base 401, and the rotation detection module 403 is disposed on the side circuit board 433. The rotation detection module 403 is spaced apart from the magnetic shaft 423, and the S pole and N pole of the magnetic shaft 423 are both oriented towards the rotation detection module 403. The rotation detection module 403 senses the magnetic changes when the magnetic shaft rotates, thereby detecting the rotation angle of the roller body 402 relative to the roller base 401. In some embodiments, the rotation detection module 403 uses Hall effect magnetic induction detection technology. In actual implementation, the rotation detection module 403 may also use other rotation detection technologies and should not be limited to this.

[0044] See also Figure 3 ,and Figure 5In this embodiment, the sound simulation module 404 is disposed on the circuit board module 31. The sound emitted by the sound simulation module 404 can be transmitted outward from the keyboard body 11. In actual implementation, the sound simulation module 404 can also be disposed in other locations and should not be limited to this. The sound simulation module 404 is a control circuit with a speaker. The sound simulation module 404 stores and emits sound. The sound simulation module 404 emits sound based on the rotation angle of the roller body 402. For example, when the roller body 402 rotates five degrees, the sound simulation module 404 emits a "click" sound, but the embodiment is not limited to this.

[0045] See Figure 4 、 Figure 5 ,and Figure 6 The vibration simulation module 405 generates vibration according to the rotation angle of the roller body 402. The vibration simulation module 405 is a vibration motor disposed in the accommodating portion 422. For example, when the roller body 402 rotates five degrees, the sound simulation module 404 emits a knocking vibration, but the present invention is not limited thereto. The accommodating portion 422 is a recessed structure disposed on the roller base 401. The vibration simulation module 405 is disposed in the accommodating portion 422. When the vibration simulation module 405 generates vibration, the force of the vibration is transmitted through the roller base 401, the roller body 402, and the touch electrode 411, so that the human finger 21 touching the touch electrode 411 feels the vibration.

[0046] See also Figure 6 The roller body 402 is generally circular. In this embodiment, the roller body 402 is composed of a small round body and a large round body, but this is not limited to this. The touch electrode 411 is a circular metal sheet that covers the outer ring of the roller body 402. The outer surface of the touch electrode 411 has a serrated structure, but this is not limited to this. In actual implementation, the outer surface of the touch electrode 411 can also be covered with a plastic cover, and this is not a limitation.

[0047] See also Figure 7 In this embodiment, when the human finger 21 touches the top of the touch electrode 411, a charge is generated at the top of the touch electrode 411, and an opposite charge is generated at the bottom of the touch electrode 411. The sensing electrode 412, spaced apart from the touch electrode 411 and close to the bottom of the touch electrode 411, generates an opposite charge as the bottom of the touch electrode 411. The touch detection module 413 detects the charge change of the sensing electrode 412 and can determine that the human finger 21 has touched the touch electrode 411. In actual implementation, other touch sensing technologies can also be configured in the scroll wheel unit 4, and the present invention is not limited to this.

[0048] For reference Figure 5 The freewheel drive module 421 cooperates with the touch detection module 413 to provide a freewheel control mode for controlling a computer. For example, when the computer is outputting a web page and the freewheel drive module 421 is activated, when the rotation detection module 403 detects the rotation of the scroll wheel body 402, the freewheel drive module 421 continuously sends a rotation signal, and the computer will continue to scroll the web page. Even if the scroll wheel body 402 stops rotating, the freewheel drive module 421 continues to send a rotation signal, and the computer will continue to scroll the web page. Only when the touch detection module 413 detects that the touch electrode 411 is touched will the freewheel drive module 421 send a stop rotation signal, and the computer will stop scrolling the web page. In actual implementation, the freewheel drive module 421 can also perform other computer control functions and should not be limited to this. When the freewheel drive module 421 is deactivated, the scroll wheel device provided on the keyboard controls the computer in the same manner as a conventional scroll wheel.

[0049] From the above description, it can be seen that the scroll wheel device provided on the keyboard of the present invention has the following functions:

[0050] 1. Can make sounds:

[0051] The sound simulation module 404 is disposed on the circuit board module 31. The sound emitted by the sound simulation module 404 can be transmitted outward from the keyboard body 11. The sound simulation module 404 emits sound according to the rotation angle of the roller body 402. Even if the roller device disposed on the keyboard does not have a ratchet structure, the sound emitted by the ratchet structure when in operation can be simulated.

[0052] 2. Can generate vibration:

[0053] The vibration simulation module 405 generates vibrations according to the rotation angle of the roller body 402. When the vibration simulation module 405 generates vibrations, the vibration force is transmitted outward through the roller base 401, the roller body 402, and the touch electrode 411, so that the human finger 21 touching the touch electrode 411 feels the vibration. The human finger 21 can understand the rotation angle of the roller body 402 from the vibration.

[0054] 3. Ability to sense touch behavior:

[0055] The touch electrode 411, the sensing electrode 412, and the touch detection module 413 cooperate to detect changes in charge on the rotating roller body 402, thereby obtaining the touch behavior of the human finger 21, and can further be used by the freewheel drive module 421 to provide a freewheel control mode to control the computer.

[0056] In summary, the scroll wheel device provided on the keyboard can not only provide basic scroll wheel operation, but the sound simulation module 404 and the vibration simulation module 405 can also simulate the sound and vibration generated when the ratchet structure moves. The touch detection module 413 senses the charge change of the touch electrode 411 through the sensing electrode 412, and can derive the behavior of the human finger 21 touching the touch electrode 411. When the freewheel drive module 421 is started, the freewheel control mode can be realized, so the purpose of this utility model can indeed be achieved.
