Description

Technical Field

[0001] This utility model relates to a scroll wheel device, and more particularly to a scroll wheel device for a computer mouse. Background Technology

[0002] Current computer mouse scroll wheels primarily rely on mechanical friction components (such as metal springs or plastic bearings) to provide resistance. These designs suffer from problems such as excessive friction, high noise levels, and poor durability. Especially after a period of use, increased friction can lead to less smooth operation or even stuttering. To improve the user experience, some technologies have attempted to reduce friction or improve the uniformity of resistance, but existing technologies still have limitations and cannot fully meet the needs of precise operation and long-term use.

[0003] Therefore, a new design is urgently needed to improve the smoothness and stability of the rollers, reduce friction and noise, and extend their service life. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art by providing a scroll wheel device for a computer mouse that has good smoothness and stability, low noise, and long service life.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a scroll wheel device for a computer mouse, comprising:

[0006] support;

[0007] An inner magnetic attraction part is fixed inside the bracket, and the inner magnetic attraction part has two or four outwardly extending outer magnetic teeth; wherein, when the inner magnetic attraction part has two outer magnetic teeth, the two outer magnetic teeth extend outward in the vertical direction; when the inner magnetic attraction part has four outer magnetic teeth, one pair of outer magnetic teeth extends outward in the vertical direction, and the other pair of outer magnetic teeth extends outward in the horizontal direction, and the two pairs of outer magnetic teeth are perpendicular to each other.

[0008] An outer roller is rotatably disposed outside the inner magnetic attraction part and is coaxially suspended outside the inner magnetic attraction part. The inner circumference of the outer roller is provided with inner circumferential teeth corresponding to the outer magnetic teeth, and the outer roller is made of a material that can be magnetically attracted.

[0009] A turn wheel is located on the outer circumference of the outer roller and is used to drive the outer roller to rotate synchronously when it is turned.

[0010] Specifically, during the process of the actuating wheel being actuated and driving the outer roller to rotate synchronously, the attraction between the outer magnetic teeth and the inner circumferential teeth is minimal when they are misaligned, and maximized when they are directly opposite each other. Thus, the change in the attraction between the outer magnetic teeth and the inner circumferential teeth creates a segmented feeling when the outer roller rotates.

[0011] In one embodiment, the inner magnetic attraction part includes a first magnetic attraction block, the two ends of which have outwardly extending outer magnetic teeth, and the two outer magnetic teeth are located on the same vertical line.

[0012] In one embodiment, the inner magnetic attraction part includes an integrally formed second magnetic attraction block, and the second magnetic attraction block has four outwardly extending outer magnetic teeth around its perimeter.

[0013] In one embodiment, the inner magnetic attraction part includes a detachable and vertically arranged third magnetic attraction block and a fourth magnetic attraction block, and the two ends of the third magnetic attraction block and the fourth magnetic attraction block respectively have extending outer magnetic teeth.

[0014] In one embodiment, one end of the inner magnetic suction part is connected to one side of the bracket via a connecting block, and the other end is connected to the other side of the bracket via a positioning shaft, thereby fixing the inner magnetic suction part to the bracket; the outer roller is rotatably suspended outside the inner magnetic suction part.

[0015] In one embodiment, the outer roller is made of ferritic steel, electrical steel, or silicon steel.

[0016] In one embodiment, the inner magnetic attraction part is made of a permanent magnet material.

[0017] In one embodiment, the bracket is made of plastic.

[0018] In one embodiment, the number of inner peripheral teeth is twenty-four.

[0019] In one embodiment, the number of external magnetic teeth is three.

[0020] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0021] This invention relates to a scroll wheel device for a computer mouse. It employs a magnetically oriented outer scroll wheel and an inner magnetic suction part positioned within the outer scroll wheel to adjust the magnetic force. When the inner circumferential teeth of the outer scroll wheel and the outer magnetic teeth of the inner magnetic suction part are misaligned, the attraction between them is minimal; when they are aligned, the attraction is maximum. This variation in attraction creates a tactile feedback on the scroll wheel. Furthermore, the structure between the outer scroll wheel and the inner magnetic suction part is simple, and the inner magnetic suction part can be easily installed within a bracket. This design is low-cost and applicable to a wide range of scenarios. Attached Figure Description

Detailed Implementation

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0033] This invention provides a scroll wheel device for a computer mouse to solve the problems of strong jerking, high friction and noise, short service life and poor operation feel of existing mouse scroll wheels.

[0034] For ease of understanding, the specific process in the embodiments of this application is described below.

[0035] Example 1

[0036] Please see Figures 1 to 4 An embodiment of this application provides a scroll wheel device for a computer mouse, comprising a bracket 1, an inner magnetic suction part 2, an outer scroll wheel 3, and a scroll wheel 4. The inner magnetic suction part 2 is fixedly disposed inside the bracket 1. The inner magnetic suction part 2 includes a first magnetic suction component 21 in a rectangular shape. The first magnetic suction component 21 is vertically fixed inside the bracket 1, and the center of the first magnetic suction component 21 and the axis of the outer scroll wheel 3 are located at the same position. The upper and lower ends of the first magnetic suction component 21 are provided with symmetrically arranged outer magnetic teeth 20. The outer scroll wheel 3 is suspended and rotatably disposed outside the inner magnetic suction part 2. The inner circumference of the inner wall of the outer scroll wheel 3 is provided with a plurality of inner circumferential teeth 30, and the outer scroll wheel 3 is made of a magnetically attracted material. The inner circumferential teeth 30 on the upper and lower sides of the inner wall of the outer scroll wheel 3 are respectively arranged at the same distance from the two outer magnetic teeth 20, but the inner circumferential teeth 30 and the outer magnetic teeth 20 do not contact each other.

[0037] See Figure 2 and Figure 3 The left end of the first magnetic component 21 in the inner magnetic part 2 is connected to one side of the bracket 1 through the connecting block 12, and the right end is connected to the other side of the bracket 1 through the positioning shaft 11. The outer roller 3 is rotatably mounted on the positioning shaft 11. When the outer roller 3 rotates around the positioning shaft 11, the position of the inner magnetic part 2 remains fixed, thus realizing that the inner magnetic part 2 does not move when the outer roller 3 rotates. This allows the outer magnetic teeth 20 and the inner peripheral teeth 30 to switch cyclically between being directly opposite each other and being staggered, thereby repeatedly changing the magnitude of the attraction between them, thus providing a tactile feedback when the outer roller 3 rotates.

[0038] Furthermore, in this embodiment, the outer roller 3 is made of ferritic steel, electrical steel, or silicon steel. The outer roller 3 only needs to be attracted by the inner magnetic part 2, so the material is not limited to the pure iron and low carbon steel mentioned above.

[0039] Furthermore, the inner magnetic attraction part 2 is made of permanent magnet material. The inner magnetic attraction part 2 is composed of a first magnetic attraction component 21 and external magnetic teeth 20 located at both ends of the first magnetic attraction component 21. The entire inner magnetic attraction part 2 is integrally set and can be magnetized to make the entire inner magnetic attraction part 2 a permanent magnet, thereby playing the role of attracting the outer roller 3. In this way, the inner magnetic attraction part 2 is relatively balanced and airtightly set inside the outer roller 3 by the external magnetic teeth 20 vertically set at the upper and lower ends.

[0040] Furthermore, the number of inner peripheral teeth 30 is twenty-four. Here, twenty-four inner peripheral teeth 30 are set so that the mouse can rotate the screen in twenty-four increments through the outer scroll wheel when in use. Of course, the number of inner peripheral teeth 30 is not limited to twenty-four and can be adjusted according to actual needs.

[0041] Furthermore, in this embodiment, the number of the outer magnetic teeth 20 is three. When the three outer magnetic teeth 20 are directly opposite the inner peripheral teeth 30 with a gap, the magnetic force generated is the greatest. The number of outer magnetic teeth 20 determines the magnitude of the attraction force. According to actual usage needs, the number of outer magnetic teeth 20 can be adjusted to meet different environmental usage requirements.

[0042] Furthermore, the bracket 1 is made of plastic. Using this material will not affect the adsorption between the outer roller 3 and the inner magnetic component 2, ensuring the stable operation of the device.

[0043] In actual operation, the actuating wheel 4 is manually actuated, thereby driving the outer roller 3 to rotate. When the outer roller 3 rotates, the inner magnetic suction part 2 does not rotate. In the initial state, the inner circumferential teeth 30 in the outer roller 3 are offset from the three outer magnetic teeth 20, and the attraction between them is minimal. When the outer magnetic teeth and the inner circumferential teeth are aligned, the attraction between them is strongest. Thus, the change in the attraction between the outer magnetic teeth 20 and the inner circumferential teeth 30 achieves the segmented feeling when the outer roller 3 rotates. Moreover, this operation does not produce noise, has a long assembly life, low cost, and is labor-saving to assemble.

[0044] Furthermore, when the outer scroll wheel 3 is rotated quickly, it will continue to rotate due to inertia, thus achieving an extremely fast effect. The extreme speed mode of the mouse scroll wheel means that the kinetic energy of the outer scroll wheel 3 overcomes the damping when it scrolls, so the scrolling speed is very fast, which is suitable for quickly browsing to the bottom of long documents.

[0045] Example 2

[0046] See Figure 8 The difference between this embodiment and embodiment one is that the inner magnetic suction part 2 includes an integrally formed second magnetic suction block 22. The second magnetic suction block 22 has four outwardly extending outer magnetic teeth 20 around its periphery. This can generate a balanced magnetic force around the inner magnetic suction part 2, making the magnetic force between the outer magnetic teeth 20 and the inner peripheral teeth 30 more stable and reliable, with a stronger sense of segmentation, a longer service life, a simpler structure, and lower cost.

[0047] Example 3

[0048] See Figures 5 to 7The difference between this embodiment and embodiment two is that the inner magnetic suction part 2 in this embodiment is a split structure. The inner magnetic suction part 2 adopts two detachable and perpendicular third magnetic suction blocks 23 and fourth magnetic suction blocks 24. A slot 230 is opened on the third magnetic suction block 23, and the fourth magnetic suction block 24 is locked in the slot 230. The third magnetic suction block 23 and the fourth magnetic suction block 24 are arranged perpendicular to each other. External magnetic teeth 20 are provided at both ends of the third magnetic suction block 23 and the fourth magnetic suction block 24, so that the four sets of external magnetic teeth 20 correspond exactly to the four sides of the inner peripheral teeth 30.

[0049] When the outer scroll wheel rotates, the inner circumferential teeth rotate along with it, but the four outer magnetic teeth remain stationary. In this way, the four sets of outer magnetic teeth and inner circumferential teeth also cycle between being directly opposite each other and being staggered, thereby increasing the suction force and enabling more stable mouse operation, thus meeting the actual usage needs.

[0050] The detachable structure in this embodiment is simple in overall structure, and is easier to install and disassemble. It also has low manufacturing cost, is more stable in use, and is convenient for practical use due to its low cost and simple installation.

[0051] In summary, this roller device uses a magnetically oriented outer roller and an inner magnetic suction part located inside the outer roller to adjust the magnetic force. When the inner circumferential teeth inside the outer roller are misaligned with the outer magnetic teeth inside the inner magnetic suction part, the attraction between them is minimal; when they are directly opposite each other, the attraction is maximum. Thus, the roller's tactile feedback is achieved through the variation in the attraction between them. At the same time, the structure between the outer roller and the inner magnetic suction part is simple, and the inner magnetic suction part can be easily installed, making it highly practical.

[0052] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
