DETAILED DESCRIPTION

[0016] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0017] The invention provides a roller device for a computer mouse, so as to solve the problems of strong frustration, large friction and noise, short service life and poor operation feel of the mouse roller in the prior art.

[0018] To facilitate understanding, the specific process in the embodiments of the present application is described below. Example

[0019] See also Figures 1 to 4A scroll wheel device for a computer mouse in an embodiment of the present application comprises a bracket 1, an inner magnetic portion 2, an outer scroll wheel 3 and a dial wheel 4; the inner magnetic portion 2 is fixedly arranged inside the bracket 1, and the inner magnetic portion 2 comprises a first magnetic component 21 in a rectangular shape, the first magnetic component 21 is vertically fixedly arranged inside the bracket 1, and the center of the first magnetic 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 component 21 are provided with symmetrically arranged outer magnetic teeth 20; the outer scroll wheel 3 is suspended and rotatably arranged outside the inner magnetic portion 2, a plurality of inner circumferential teeth 30 are arranged on the circumference of the inner wall of the outer scroll wheel 3, and the outer scroll wheel 3 is made of a material that can be magnetically attracted, and 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 are not in contact with each other.

[0020] See also 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 a connecting block 12, and the right end is connected to the other side of the bracket 1 through a positioning shaft 11; the outer roller 3 is rotatably arranged on the positioning shaft 11, so that when the outer roller 3 rotates around the positioning shaft 11, the position of the inner magnetic part 2 is fixed, thereby achieving the inner magnetic part 2 not moving when the outer roller 3 rotates, so that the outer magnetic teeth 20 and the inner peripheral teeth 30 can be cyclically switched between facing each other in the air and staggered in the air, and then repeatedly change the suction force between the two, so as to provide a sense of paragraph when the outer roller 3 rotates.

[0021] Furthermore, in this embodiment, the material of the outer roller 3 is ferrite or electrical steel or silicon steel. The outer roller 3 only needs to be adsorbed by the inner magnetic attraction part 2, so the material is not limited to the above-mentioned pure iron and low-carbon steel.

[0022] Furthermore, the material of the inner magnetic attraction part 2 is a permanent magnetic 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 arranged as an integral whole, and the entire inner magnetic attraction part 2 can be magnetized to become a permanent magnet, so that it can play a role in adsorbing the outer roller 3. In this way, the inner magnetic attraction part 2 is relatively balanced and spaced inside the outer roller 3 through the external magnetic teeth 20 vertically arranged at the upper and lower ends.

[0023] Furthermore, the number of the inner circumferential teeth 30 is twenty-four. Twenty-four inner circumferential teeth 30 are set here, so that the mouse can scroll the screen by twenty-four grids through the outer scroll wheel when in use. Of course, the number of the inner circumferential teeth 30 is not limited to twenty-four and can be adjusted according to actual needs.

[0024] Furthermore, in this embodiment, the number of the external magnetic teeth 20 is three. When the three external magnetic teeth 20 are facing the inner peripheral teeth 30 in the air, the generated magnetic force is the largest. The number of the external magnetic teeth 20 determines the size of the suction force. According to actual usage requirements, the number of the external magnetic teeth 20 can be adjusted to meet the usage requirements of different environments.

[0025] Furthermore, the bracket 1 is made of plastic. The use of the above material will not affect the adsorption between the outer roller 3 and the inner magnetic attraction component 2, thereby ensuring the stable operation of the device.

[0026] During specific operation, the shifting wheel 4 is manually shifted to drive the outer roller 3 to rotate. When the outer roller 3 rotates, the inner magnetic attraction part 2 will not rotate. In the initial state, the inner peripheral teeth 30 in the outer roller 3 are offset from the three outer magnetic teeth 20. At this time, the suction force between the two is the smallest. When the outer magnetic teeth and the inner peripheral teeth are directly opposite to each other in the air, the suction force between the two is the strongest. Thus, the sense of segmentation when the outer roller 3 rotates is achieved by the change in the suction force between the outer magnetic teeth 20 and the inner peripheral teeth 30. In addition, such operation will not generate noise, the assembly has a long service life, low cost, and labor-saving assembly.

[0027] And when the outer scroll wheel 3 is rotated quickly, under the action of inertia, the outer scroll wheel 3 will continue to rotate, thereby achieving an extreme speed effect. The extreme speed mode of the mouse wheel means that the kinetic energy overcomes the damping when the outer scroll wheel 3 rolls, so the scrolling speed is very fast, which is suitable for quickly browsing to the bottom of a long document. Example

[0028] See also Figure 8 The difference between this embodiment and the first embodiment is that the inner magnetic attraction portion 2 includes an integrally formed second magnetic attraction block 22, and four outer magnetic teeth 20 extending outward are arranged around the second magnetic attraction block 22, so that a balanced magnetic force can be generated around the inner magnetic attraction portion 2, so that the magnetic force generated between the outer magnetic teeth 20 and the inner peripheral teeth 30 is more stable and reliable, the paragraph sense is stronger, the service life is longer, the structure is simple, and the cost is low. Example

[0029] See also Figures 5 to 7 The difference between this embodiment and the second embodiment is that the inner magnetic attraction part 2 in this embodiment is a split structure, and the inner magnetic attraction part 2 adopts two detachable and perpendicular third magnetic attraction blocks 23 and fourth magnetic attraction blocks 24. A slot 230 is opened on the third magnetic attraction block 23, and the fourth magnetic attraction block 24 is clamped in the slot 230. The third magnetic attraction block 23 and the fourth magnetic attraction block 24 are arranged perpendicular to each other, and external magnetic teeth 20 are respectively provided at both ends of the third magnetic attraction block 23 and the fourth magnetic attraction block 24, so that the four groups of external magnetic teeth 20 just correspond to the four sides of the inner peripheral teeth 30.

[0030] When the outer scroll wheel rotates, the inner teeth follow it, but the four outer magnetic teeth do not move. In this way, the four groups of outer magnetic teeth and the inner teeth also cyclically move between facing each other in the air and staggered in the air, thereby increasing the suction force, allowing for more stable mouse operation and meeting actual usage needs.

[0031] The detachable structure in this embodiment has a simple overall structure, and is easier to install and disassemble, and has a low manufacturing cost. At the same time, it is more stable to use, has a low cost, is simple to install, and is convenient for actual use.

[0032] To sum up, the roller device adopts an outer roller that can be attracted by magnets, and an inner magnetic attraction part arranged in the outer roller to adjust the change of magnetic force. When the inner peripheral teeth in the outer roller and the outer magnetic teeth in the inner magnetic attraction part are offset in the air, the suction force between the two is the smallest, and when the two are facing each other in the air, the suction force between the two is the largest, thereby realizing the segmentation feeling of the roller through the change of the suction force between the two; at the same time, the structure between the outer roller and the inner magnetic attraction part is simple, and the inner magnetic attraction part can also be easily installed, and it is highly practical.

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
