Description

Technical Field

[0001] This application belongs to the field of mouse technology and relates to a mouse scroll wheel mechanism and a mouse. Background Technology

[0002] As an important human-computer interaction device, the mouse's scroll wheel is used to enable page scrolling, zooming, and other functions, directly affecting the user's operating experience. Traditional mouse scroll wheels mostly use mechanical encoders or optical sensors to detect scrolling signals. While these technologies are mature, they have inherent limitations.

[0003] Mechanical encoder rollers generate signals by the contact and disconnection of physical electrical contacts. After prolonged use, they are prone to wear and oxidation, leading to poor contact, signal fluctuations, false triggering, or complete failure, resulting in limited reliability and lifespan. Furthermore, the tactile feedback produced during scrolling is typically generated by friction and impact from the mechanical structure. This tactile feedback is harsh and noisy, and prolonged operation can easily cause finger fatigue for users. Utility Model Content

[0004] To overcome the problems existing in the related technologies, this application aims to provide a mouse scroll wheel mechanism and mouse that can sense the rotation of the scroll wheel and produce a tactile feedback when the scroll wheel rotates.

[0029] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0031] Firstly, this embodiment discloses a mouse scroll wheel mechanism, such as... Figures 1-5 As shown, it includes: a bracket 1 with a receiving cavity 11, in which a rotating shaft 3, a magnetic wheel 4, a fixing frame 5 and a roller 6 are provided. The roller 6 is connected to the magnetic wheel 4 through the fixing frame 5. The magnetic wheel 4 is located on the rotating shaft 3, and the rotating shaft 3 is located on the bracket 1.

[0032] The inner wall of the magnetic wheel 4 is provided with a plurality of protrusions 41 extending radially thereon. The plurality of protrusions 41 are arranged in a circular array around the rotating shaft 3. A gap is formed between adjacent protrusions 41. The magnetic strength at the gap is lower than the magnetic strength at the protrusion 41. The magnetic field strength of the magnetic wheel 4 in the circumferential direction exhibits a periodic distribution.

[0033] It also includes a Hall sensor 7 mounted on the bracket 1. The Hall sensor is located on the side of the magnetic wheel 4 and corresponds to the protrusion 41. The Hall sensor 7 is used to sense the change in the magnetic field of the magnetic wheel 4 during rotation.

[0034] It should be noted that the protrusion 41 of the magnetic wheel 4 is made of permanent magnet material, or the magnetic wheel 4 is made of permanent magnet material, including a first magnetic pole 8, a second magnetic pole 81 and a non-magnetic pole 82. The first magnetic pole 8 and the second magnetic pole 81 are the south pole and the north pole, respectively. The non-magnetic pole 82 is weakly magnetic or has no magnetism. The fixing frame 5 is used to fix the magnetic wheel 4 and is also fixed to the roller 6, so that the roller 6, the fixing frame 5 and the magnetic wheel 4 can rotate synchronously. The rotating shaft 3 is fixed to the bracket 1 and the fixing wheel 2. The magnetic wheel 4 is rotatably connected to the rotating shaft 3. When the roller 6 is turned, the roller 6, the fixing frame 5 and the magnetic wheel 4 can rotate synchronously outside the rotating shaft 3.

[0035] It should be noted that after the bracket 1 is assembled with the mouse, the scroll wheel 6 rotates, which can drive the fixed frame 5 and the magnetic wheel 4 to rotate synchronously. The convex strips 41 of the magnetic wheel 4 are magnetic, and the magnetic force is low in the gap between the convex strips 41. That is, its magnetic field changes periodically. When the scroll wheel 6 rotates, the Hall sensor 7 can sense the periodic magnetic field change, so as to achieve the purpose of controlling the computer by rotating the mouse scroll wheel.

[0036] like Figure 2 and Figure 4 As shown, it also includes a fixed wheel 2 located inside the magnetic wheel 4. One end of the rotating shaft 3 is mounted on the bracket 1, and the other end is mounted on the fixed wheel 2. The fixed wheel 2 is fixedly mounted on the bracket 1.

[0037] At least one magnetic block 22 is provided on the outer side of the fixed wheel 2. When the magnetic wheel 4 rotates, the convex strip 41 periodically passes through the magnetic block 22 and generates magnetic attraction with each other, so that the roller 6 produces a sense of pause during rotation.

[0038] It should be noted that the magnetic wheel 4 can have a through hole 42 to reduce weight. The through hole 42 is located on the raised side of the ridge 41 facing the center of the magnetic wheel 4 to avoid affecting the magnetic field of the ridge 41.

[0039] like Figure 2 and Figure 3 As shown, the bracket 1 is provided with a slot 12, and the fixed wheel 2 is provided with a protrusion 23 that cooperates with the slot 12. The fixed wheel 2 is fixed on the bracket 1 by the snap-fit ​​cooperation between the protrusion 23 and the slot 12.

[0040] It should be noted that the slot 12 can be a through hole or a non-through groove. The slot 12 cooperates with the protrusion 23 to restrict the rotation of the fixed wheel 2.

[0041] It should be noted that the roller 6, the fixed frame 5, the magnetic wheel 4 and the fixed wheel 2 are coaxially sleeved. The convex part 23 of the fixed wheel 2 is in a "convex" shape, which can limit the fixed wheel 2. The fixed wheel 2 is used to cooperate with the bracket 1 to install the rotating shaft 3, and a groove is opened to install the magnetic block 22. Furthermore, when the magnetic wheel 4 rotates, the magnetic block 22 cooperates with the convex strip 41 to generate a sense of paragraph.

[0042] As Figure 2 and Figure 4 shown, an installation groove 21 recessed inward is provided on the outer side surface of the fixed wheel 2, and the magnetic block 22 is arranged inside the installation groove 21.

[0043] It should be noted that when the convex strip 41 passes through the magnetic block 22, the magnetic attraction force between the two is relatively large. When the convex strip gap passes through the magnetic block 22, the magnetic attraction force between the two is relatively small. When the roller rotates, the convex strip 41 and the convex strip gap pass through the magnetic block 22 in sequence, which can generate a sense of paragraph.

[0044] As Figure 2 and Figure 4 shown, a radially protruding clamping strip 43 is provided on the outer peripheral edge of the magnetic wheel 4, and a clamping groove 51 is provided on the fixed frame 5 corresponding to the clamping strip 43. The clamping strip 43 is in clamping fit with the clamping groove 51 to limit the relative rotation between the magnetic wheel 4 and the fixed frame 5.

[0045] As Figure 1 and Figure 2 shown, it further includes a circuit board, and the Hall sensor 7 is integrated on the circuit board. The circuit board has a signal output end.

[0046] It should be noted that the position of the fixed wheel 2 is fixed, and the magnetic block 22 is arranged on the side of the fixed wheel 2 far from the Hall sensor 7, and there is a certain distance between the two, which can reduce the influence of the magnetic block 22 on the Hall sensor 7.

[0047] As Figures 1-3 shown, a fixing frame 13 is provided on the bracket 1, and the circuit board is fixedly arranged in the fixing frame 13.

[0048] As Figure 2 shown, a limiting ring 52 is provided at one end of the fixed frame 5 far from the fixed wheel 2, and the limiting ring 52 is used to limit the magnetic wheel 4.

[0049] As Figure 1 and Figure 2 shown, the outer surface of the roller 6 is provided with anti-slip lines, and the anti-slip lines are used to increase the friction force.

[0050] In the second aspect, this embodiment discloses a mouse, including the mouse roller mechanism as in the first aspect.

[0051] Working principle: The convex strip 41 set on the inner wall of the magnetic wheel 4 forms a periodic magnetic field change when the magnetic wheel 4 rotates with the roller 6, so that the Hall sensor 7 can sense the change in magnetic field strength and obtain the rotation information of the roller 6. The magnetic block 22 is magnetically attracted to the convex strip 41, which can produce a segmented feeling when the roller 6 rotates.

[0052] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
