Description

Technical Field

[0002] A magnetically damped scroll wheel structure is a rotating structure that uses magnetic materials to create a magnetic damping effect. It can be used in applications such as keyboard or mouse scroll wheels, automotive instrument knobs, and household appliance control knobs. The magnetic damping of a magnetically damped scroll wheel structure is primarily used to control the rotational speed of the rotating structure or provide a damping effect. The magnetic damping effect improves the user's feel when scrolling the scroll wheel structure, making the rotation of the rotating structure smoother and more controllable. Compared to traditional encoder scroll wheels that use metal contact friction, the contactless magnetic damping effect extends the life of the scroll wheel knob. For example, the mouse we commonly use has a scroll wheel. To improve the feel and controllability of computer page manipulation when the user scrolls the mouse wheel, the mouse wheel needs to have both segment feedback and damping feedback.

[0003] However, taking the mouse wheel as an example, the internal structure and magnetic strength of current magnetic damping mouse wheels are fixed, so the feel and damping of the scroll wheel during rotation are usually fixed and cannot be adjusted.

[0023] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0024] The present invention provides Figure 1 、 Figure 2 、 Figure 3 and Figure 4The scroll wheel structure shown here features adjustable damping. This structure uses magnetic material combined with a magnetic field coil 24 to generate magnetic damping. Applications include keyboard or mouse scroll wheels, automotive instrument knobs, and household appliance control knobs. The scroll wheel's magnetic damping is primarily used to control the rotational speed or provide a damping effect, improving the user's feel and ensuring smoother and more controllable rotation. The main structure of the present invention includes: a mounting base 1, a first annular shaft 2 and at least one second annular shaft 4; the first annular shaft 2 is fixed on the mounting base 1, and a plurality of first grooves 21 are evenly provided on at least one end surface of the first annular shaft 2, and a first boss 22 is formed between two adjacent first grooves 21; the second annular shaft 4 is rotatably provided on the mounting base 1 and is coaxially provided with the first annular shaft 2, and a plurality of second grooves 41 are evenly provided on the surface of one end of the second annular shaft 4 facing the first boss 22, and a second boss 42 is formed between two adjacent second grooves 41; wherein, at least one magnetic field coil 24 is provided on the first annular shaft 2, and the magnetic field coil 24 is used to adjust the magnetic strength of the first annular shaft 2. Figure 6 and Figure 7 As shown, at least two electrodes 241 are provided on the magnetic field coil 24, and the electrodes 241 are used to connect to an external circuit. There is a gap between the first boss 22 and the second boss 42. The first boss 22 and the second boss 42 are arranged in a one-to-one correspondence and generate a mutual magnetic attraction force. The mounting base 1 is used to fix the first annular shaft 2, so that the first annular shaft 2 acts as a stator, and the second annular shaft 4 is coaxially connected to the first annular shaft 2 for rotation, and the second annular shaft 4 acts as a rotor. The first annular shaft 2 and the second annular shaft 4 can be a metal shaft that can be magnetically attracted, or a magnetic shaft with a magnetic field strength. When the magnetic field coil 24 is energized, the magnetic attraction strength between the first annular shaft 2 and the second annular shaft 4 will change, thereby adjusting the damping size during the rotation between the first annular shaft 2 and the second annular shaft 4.

[0025] Specifically, the mounting base 1 is used to mount and secure various structural components. Depending on functional requirements, different functional components, such as rotary switches and photoelectric switches, can be installed on the mounting base 1. A connecting shaft 11 is provided on the mounting base 1. In some embodiments, the connecting shaft 11 is configured as a metal shaft to ensure the structural strength and durability of the rotating structure. The first annular shaft 2 is sleeved on the connecting shaft 11 and secured to the mounting base 1. A plurality of first grooves 21 are uniformly formed on at least one of the end surfaces of the first annular shaft 2. The plurality of first grooves 21 extend in a direction away from the axis of the first annular shaft 2, and a first boss 22 is formed between two adjacent first grooves 21.

[0026] It's important to note that, for example, current magnetically damped mouse wheels have a fixed internal structure and magnetic strength, so the feel and damping of the scroll wheel during rotation are typically fixed and unadjustable. Users can't adjust the damping feedback of the scroll wheel to their own preferences.

[0027] This solution can change the magnetic field strength of the first annular shaft 2 by adjusting the current magnitude and direction of the magnetic field coil 24, thereby adjusting the magnetic attraction between the first boss 22 and the second boss 42, making the damping of the second annular shaft 4 adjustable during rotation. Specifically, when the second annular shaft 4 is rotated, the damping value of the attraction between the first annular shaft 2 and the second annular shaft 4 changes, producing a light and heavy feedback of the hand feel. At the same time, the kinetic energy of the first annular shaft 2 can be converted into electrical energy during rotation, achieving the technical effect of energy collection and power generation. It can be applied to fields such as mice, keyboards, and car dashboards. When the outer ring wheel 3 accelerates, the torque inertia can be used to make the second annular shaft 4 rotate rapidly until the speed of the outer ring wheel 3 and the second annular shaft 4 slows to a point where the damping can no longer be overcome and the speed is reduced to a stop.

[0028] Further, such as Figure 1 、 Figure 3 As shown, at least one of the first annular shaft 2 and the second annular shaft 4 is a magnetically attractive annular shaft. This allows the first boss 22 and the second boss 42 to be attracted to each other due to the magnetic attraction. In actual implementation, in Example 1, the first annular shaft 2 is a magnetically attractive annular shaft, and the second annular shaft 4 is a magnetically attractive metal shaft. In Example 2, the second annular shaft 4 is a magnetically attractive annular shaft; the first annular shaft 2 is a magnetically attractive metal shaft. In Example 3, both the first annular shaft 2 and the second annular shaft 4 are magnetically attractive annular shafts.

[0029] Among them, in embodiment 1, the first annular shaft 2 is an annular shaft with magnetic attraction, and the second annular shaft 4 is a metal shaft that can be magnetically attracted. Since the first annular shaft 2 is an annular shaft with magnetic attraction, the first boss 22 with magnetic attraction can magnetically attract the second boss 42. When the magnetic field coil 24 is energized, the magnetic attraction of the first annular shaft 2 is suppressed or enhanced. The magnetic attraction between the first boss 22 and the second boss 42 is then changed, thereby achieving the adjustable damping size and paragraph feel of the roller during rotation, thereby achieving the adjustment of the lightness or heaviness of the hand feel. At the same time, the kinetic energy of the roller can be converted into electrical energy during rotation to achieve the technical effect of collecting electrical energy.

[0030] In the second embodiment, the second annular shaft 4 is a magnetically attractive annular shaft; the first annular shaft 2 is a magnetically attractive metal shaft. Because the second annular shaft 4 is a magnetically attractive annular shaft, even when the magnetic field coil 24 is not energized, the magnetically attractive second boss 42 can still magnetically attract the first boss 22. When the magnetic field coil 24 is energized, the magnetic attraction of the first annular shaft 2 is suppressed or enhanced. This causes the magnetic attraction between the first boss 22 and the second boss 42 to change, thereby adjusting the damping and feel of the scroll wheel during rotation, thereby achieving a light or heavy feel. It is also important to note that because the second annular shaft 4 is magnetic, when the second annular shaft 4 rotates, the magnetic field coil 24 on the first annular shaft 2 can cut the magnetic induction lines of the second annular shaft 4, causing the magnetic field coil 24 to generate electrical energy, which is collected in the mouse's power storage device, achieving the technical effect of converting kinetic energy into electrical energy.

[0031] In Example 3, since both the first annular shaft 2 and the second annular shaft 4 are annular shafts with magnetic attraction, when the magnetic field coil 24 is not energized, the first boss 22 and the second boss 42 are attracted to each other by the magnetic attraction, generating a significant magnetic damping effect when the second annular shaft 4 rotates. When the magnetic field coil 24 is energized, the magnetic attraction of the first annular shaft 2 is suppressed or enhanced. This in turn causes the magnetic attraction between the first boss 22 and the second boss 42 to change, thereby adjusting the damping and feel of the scroll wheel during rotation, thereby achieving a light or heavy feel. Similar to Example 2, since the second annular shaft 4 is magnetic, when the second annular shaft 4 rotates, the magnetic field coil 24 on the first annular shaft 2 can cut the magnetic induction lines of the second annular shaft 4, causing the magnetic field coil 24 to generate electrical energy, which is collected in the mouse's power storage device, achieving the technical effect of converting kinetic energy into electrical energy.

[0032] In Examples 1 and 3 above, the provision of the first grooves 21 weakens the magnetism at that location. This allows the magnetic attraction on the end surface of the first annular shaft 2 to be evenly distributed across the plurality of first bosses 22. The outer ring pulley 3 is sleeved onto the connecting shaft 11. The second annular shaft 4 is positioned at the axis of the outer ring pulley 3 and on the side of the first annular shaft 2. The surface of the second annular shaft 4, near one end thereof, is uniformly provided with a plurality of second grooves 41. These second grooves 41 extend away from the axis of the second annular shaft 4, with second bosses 42 formed between adjacent second grooves 41. Similarly, the provision of the second grooves 41 weakens the magnetism at that location. This allows the magnetic attraction on the end surface of the second annular shaft 4 to be evenly distributed across the plurality of second bosses 42. The first bosses 22 and second bosses 42 are arranged in a one-to-one correspondence with each other by means of magnetic attraction, with a gap maintained between them. In some embodiments, a shaft step is coaxially provided on the connecting shaft 11, located between the first bosses 22 and second bosses 42. The shaft step maintains a gap and a coaxial connection between the first boss 22 and the second boss 42. In some embodiments, the shaft step is integrally formed with the connecting shaft 11, and both the shaft step and the connecting shaft 11 are made of non-magnetic materials to avoid disrupting the magnetic fields of the first boss 22 and the second boss 42.

[0033] As can be seen, the first annular shaft 2, the second annular shaft 4, and the outer ring wheel 3 are directly or indirectly mounted on the connecting shaft 11. When the outer ring wheel 3 rotates, the second annular shaft 4 rotates synchronously. At this point, the axial magnetic attraction between the two adjacent magnetic surfaces of the second annular shaft 4 and the first annular shaft 2 changes. This in turn changes the damping value of the outer ring wheel 3 during rotation, producing a light and heavy feedback feel.

[0034] In some embodiments, a first annular shaft 2 and two second annular shafts 4 are coaxially arranged on the connecting shaft 11, and the first annular shaft 2 and the connecting shaft 11 are fixedly connected to the mounting base 1, and a plurality of first grooves 21 are evenly provided on the two end surfaces of the first annular shaft 2, and a first boss 22 is formed between two adjacent first grooves 21; the two second annular shafts 4 are respectively rotatably arranged on the mounting base 1, and a plurality of second grooves 41 are evenly provided on the surface of one end of the second annular shaft 4 facing the first boss 22, and a second boss 42 is formed between two adjacent second grooves 41; wherein, the two second bosses 42 respectively have gaps between the two ends of the first boss 22, and the first boss 22 and the second boss 42 are arranged one by one and generate attractive magnetic forces.

[0035] Furthermore, the magnetic poles of the first boss 22 and the second boss 42 are opposite. It is understood that the opposite magnetic poles of the first boss 22 and the second boss 42 can make them attract each other, thereby improving the magnetic damping effect generated between them.

[0036] Further, such as Figure 1 、 Figure 3 As shown, the second annular shaft 4 is an annular shaft with magnetic attraction, and the magnetic field coil 24 is used to adjust the magnetic strength of the first annular shaft 2 or cut the magnetic induction lines of the second annular shaft 4 in the rotating state to generate electrical energy. The details are as described in the above-mentioned embodiment 2 and embodiment 3.

[0037] Further, such as Figure 3 、 Figure 7 As shown, an annular groove 23 is formed on the outer circumference of the first annular shaft 2, and a magnetic field coil 24 is wound in the annular groove 23 around the circumference of the first annular shaft 2. In this embodiment, the annular groove 23 is formed on the outer circumference of the first annular shaft 2, so that the magnetic field coil 24 can be wound in the annular groove 23. Ultimately, the outer wall of the first annular shaft 2 can be kept flush, making the overall roller structure more compact and beautiful.

[0038] Furthermore, the magnetic field coil 24 is a metallic copper coil. As will be appreciated, metallic copper coils have excellent electrical conductivity, enabling efficient current transmission and reducing energy loss (such as heat generation). Copper coils can generate strong magnetic fields and are sensitive to electromagnetic interference, effectively cutting the magnetic flux lines of the second annular shaft 4.

[0039] Further, such as Figure 5 、 Figure 6 and Figure 8 As shown, the number of the first grooves 21 is the same as the number of the second grooves 41 , the size of the first boss 22 is the same as the size of the second boss 42 , and the shape of the first boss 22 is the same as the shape of the second boss 42 .

[0040] It can be understood that in order to make the segment feedback of the damping-adjustable roller structure clearer during rotation, the number of first grooves 21 needs to be the same as the number of second grooves 41, the size of the first boss 22 needs to be the same as the size of the second boss 42, and the shape of the first boss 22 needs to be the same as the shape of the second boss 42.

[0041] Further, such as Figure 5 、 Figure 6 As shown, the first groove 21 and the second groove 41 are both U-shaped grooves.

[0042] In some preferred embodiments, both the first groove 21 and the second groove 41 are U-shaped grooves. In some other embodiments, the first groove 21 and the second groove 41 can also be configured as V-shaped grooves. The V-shaped groove configuration allows the bosses (the first boss 22 and the second boss 42) to have a structure that is wider at the bottom and narrower at the top. This structural design allows the magnetic attraction force on the magnetic end faces of the annular shafts (the first annular shaft 2 and the second annular shaft 4) to follow the slope of the V-shaped groove and concentrate at the tops of the bosses (the first boss 22 and the second boss 42). This provides clearer feedback between the first annular shaft 2 and the second annular shaft 4, and enhances the magnetic damping effect generated between them.

[0043] Further, such as Figure 3 、 Figure 4 As shown, the second annular shaft 4 is coaxially provided with an outer ring wheel 3, which is detachably connected to the second annular shaft 4. The outer ring wheel 3 is a metal wheel rim. The second annular shaft 4 is provided with several locating pins 43, and the second annular shaft 4 is fixedly connected to the outer ring wheel 3 via the locating pins 43. It is understandable that the metal wheel rim has a larger mass, which makes the rotational inertia of the outer wheel rim 32 larger. This thereby makes its rolling stroke longer. The second annular shaft 4 is connected to the outer ring wheel 3 via the locating pins 43, which can prevent slipping between the two. In some embodiments, the second annular shaft 4 is detachably connected to the outer ring wheel 3.

[0044] Further, such as Figure 3 、 Figure 4 As shown, the outer ring wheel 3 includes a grating clamping ring 31 and an outer rim 32. The grating clamping ring 31 is coaxially arranged with the second annular shaft 4. The grating clamping ring 31 is provided with a plurality of light holes 312 in the circumferential direction, extending parallel to the axis of the grating clamping ring 31. The outer rim 32 is sleeved on the outer wall of the grating clamping ring 31. The grating clamping ring 31 has an escape groove 311 at the axis of the grating clamping ring 31, which is used to avoid the first annular shaft 2 and the second annular shaft 4. The first and second annular shafts 2 and 4 are accommodated in the escape groove 311 at the axis of the grating clamping ring 31, making the entire rotating wheel structure more compact and more integrated. Furthermore, the wheel structure formed by the first annular shaft 2, the second annular shaft 4, and the grating clamping ring 31 is more rational.

[0045] A second aspect of the present application provides a damping adjustment method for the damping-adjustable roller structure according to any one of the first aspects, the damping adjustment method comprising the following steps: Step 1: Receive circuit adjustment instructions through the two electrodes 241 of the magnetic field coil 24, and adjust the current size and direction of the magnetic field coil 24 on the first annular shaft 2 according to the adjustment instructions to change the magnetic attraction between the first annular shaft 2 and the second annular shaft 4, thereby changing the damping between the first boss 22 and the second boss 42; wherein the second annular shaft 4 is rotated by the outer ring wheel 3, the first boss 22 is provided on the first annular shaft 2, and the second boss 42 is provided on the second annular shaft 4; Step 2: When the outer ring wheel 3 is rolled by the user, the outer ring wheel 3 drives the second annular shaft 4 to rotate; Step 3: Rotate the second annular shaft 4 to cause an offset between the first boss 22 on the first annular shaft 2 and the second boss 42 on the second annular shaft 4, wherein the first boss 22 and the second boss 42 correspond to each other and attract each other; Step 4: damping is generated between the first boss 22 and the second boss 42 by changing the magnetic attraction between the first boss 22 and the second boss 42; Step 5: Adjust the current of the magnetic field coil 24 on the first annular shaft 2 to increase or decrease the magnetic attraction of the first annular shaft 2, thereby increasing or decreasing the damping between the first boss 22 and the second boss 42. For details, refer to the above-mentioned embodiments 1, 2, and 3.

[0046] This application solution can be applied to the fields of mouse, keyboard, car dashboard, etc. In the field of mouse, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown in FIG, the damping adjustable roller structure of the present application is configured as a mouse roller. In the field of keyboards and car dashboards, for example Figure 9 、 Figure 10 and Figure 11 As shown, the damping-adjustable roller structure of the present application solution can be configured as a volume control roller of a keyboard or a car dashboard (it can also be a page scrolling control device).

[0047] Therefore, the third aspect of the present application provides a mouse, which includes: a mouse housing, a circuit board and the damping-adjustable roller structure as described above, and a number of buttons are provided on the mouse housing; the circuit board is arranged in the mouse housing, and a light-emitting component and a photosensitive receiving element are provided on the circuit board; the damping-adjustable roller structure is arranged in the mouse housing; wherein the light-emitting component and the photosensitive receiving element are respectively arranged on both sides of the damping-adjustable roller structure, and the light-emitting component and the photosensitive receiving element are respectively arranged corresponding to the two ends of the light-through hole 312.

[0048] In some embodiments, the light emitting element and the light receiving element are disposed at the same end of the light hole 312. A reflector is disposed at the other end of the light hole 312 to reflect light from the light hole 312 onto the light receiving element, thereby achieving the technical effect of scroll wheel sensing.

[0049] In summary, the present application provides a roller structure with adjustable damping and a damping adjustment method. This solution can change the magnetic field strength of the first annular shaft 2 by adjusting the current size and direction of the magnetic field coil 24, and then adjust the magnetic attraction force between the first boss 22 and the second boss 42, so that the damping size of the second annular shaft 4 during rotation is adjustable. Specifically, when the second annular shaft 4 is rotated, the damping value of the attraction between the first annular shaft 2 and the second annular shaft 4 changes, producing light and heavy segment feedback of the hand feel. At the same time, the magnetic field coil 24 can also be used to cut the magnetic induction line, converting the kinetic energy of the second annular shaft 4 into electrical energy, thereby achieving the technical effect of electricity collection and power generation. It can be applied to fields such as mice, keyboards, and car dashboards.

[0050] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
