Abstract
Description
Technical Field
[0001] The utility model relates to a mouse roller, in particular to a multi-pole magnetic ring type mouse roller. Background Art
[0002] A mouse is a common input device used in computer operations. It is used to position the cursor on the screen and quickly scroll documents or web pages to the desired location on the screen by rotating the scroll wheel. Optical mice are commonly used today. When the mouse wheel is rotated, the metal shaft of the wheel drives the rotor of the encoder to rotate synchronously with the wheel, converting the angular displacement into a digital signal, thereby controlling the scrolling of the computer page.
[0003] The scrolling resistance mechanism of the existing mouse encoder is of mechanical contact type, which is not smooth to use and has a weak sense of paragraphing. In addition, the contact type will wear out after long-term use, and the resistance will decrease, which will reduce the sense of paragraphing. It is difficult for users to feel the rotation state of the scroll wheel, which brings many inconveniences to customers and makes it impossible to meet their needs. Utility Model Content
[0004] The utility model aims to overcome the deficiencies of the prior art and provide a multi-pole magnetic ring mouse wheel with low cost, simple assembly and good user experience.

[0006] base plate;
[0007] A roller bracket is arranged on the bottom plate;
[0008] A roller, movably mounted on the roller bracket;
[0009] A multi-pole magnetic ring, the multi-pole magnetic ring is sleeved on the roller, the circumferential surface of the multi-pole magnetic ring is magnetized with an even number of magnetic poles, and the even number of magnetic poles are distributed at intervals of N poles and S poles;
[0010] The magnetic block is arranged on the bottom plate and is located directly below the multi-pole magnetic ring;
[0011] When the roller drives the multipolar magnetic ring to rotate synchronously, the magnetic attraction between the magnetic poles on the multipolar magnetic ring and the pair of magnetic blocks generates a magnetic damping force, which forms a damping force on the rotation of the roller.
[0012] Furthermore, a Hall sensor is provided on the bottom plate and is located on the opposite side of the pair of magnetic blocks, wherein the detection center of the Hall sensor is located on the central circumference line of the circumferential surface of the roller, for sensing the rotation angle of the roller.
[0013] Furthermore, the number of the magnetic poles is twenty-four, twenty-eight, thirty-two or thirty-six.
[0014] Furthermore, the roller is covered with a leather cover.
[0015] Furthermore, a shaft sleeve is provided at the center of the roller; a metal shaft is installed in the shaft sleeve, and the roller is fixed to the two roller brackets through the shaft sleeve and the metal shaft.
[0016] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:
[0017] The multi-pole magnetic ring type mouse scroll wheel of the utility model is provided with a multi-pole magnetic ring in the circumferential direction of the scroll wheel. A plurality of magnetic poles are magnetized on the circumferential surface of the multi-pole magnetic ring. The plurality of magnetic poles are distributed in a manner of spacing between N poles and S poles, and an iron-absorbing block is provided below the multi-pole magnetic ring.

[0024] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.
[0025] The utility model provides a multi-pole magnetic ring mouse wheel to solve the problem that mechanical contact mice in the prior art wear out during long-term use, reduce resistance, reduce the sense of paragraph, and make it difficult for users to feel the rotation state of the wheel, thus making it difficult to use properly.
[0026] For ease of understanding, the specific process in the embodiment of this application is described below. Figures 1 to 3 A multi-pole magnetic ring type mouse scroll wheel in an embodiment of the present application includes a base plate 1, a scroll wheel bracket 2, a scroll wheel 3, an iron-absorbing block 4 and a multi-pole magnetic ring 9; the scroll wheel bracket 2 is arranged on the base plate 1; the scroll wheel 3 is movably installed on the scroll wheel bracket 2; the multi-pole magnetic ring 9 is sleeved on the scroll wheel 3, and an even number of magnetic poles are magnetized on the circumferential surface of the multi-pole magnetic ring 9, and the even number of magnetic poles are distributed at intervals of N poles and S poles; the iron-absorbing block 4 is arranged on the base plate 1 and is located directly below the scroll wheel 3.
[0027] The multi-pole magnetic ring type mouse scroll wheel of the present invention, when the scroll wheel 3 rotates, the multi-pole magnetic ring 9 rotates synchronously with the scroll wheel 3, so that the magnetic attraction between the multiple magnetic poles on the multi-pole magnetic ring 9 and the pair of magnetic blocks 4 generates a magnetic damping force. The magnetic damping force forms a damping force on the rotation of the scroll wheel 3, and the user can clearly feel the rotation state of the scroll wheel, providing a good user experience.
[0028] Further, based on Figure 3 The number of the magnetic poles is twenty-four, and the twenty-four magnetic poles are evenly distributed on the circumferential surface of the roller 3 by magnetization. The magnetization direction of the twenty-four magnetic poles is on the radial line of the roller 3, and the plurality of magnetic poles are distributed with polarity spaced between the N pole and the S pole.
[0029] In the present invention, multiple magnetic poles are constructed on the multipolar magnetic ring 9 by magnetization, and the distribution of the magnetic poles is an alternating distribution of N poles and S poles. This magnetization method is simple and labor-saving to operate, and can meet the needs of mass production and processing of enterprises.
[0030] Secondly, the present invention adopts the magnetic block 4 to achieve mutual attraction with the magnetic poles on the multi-polar magnetic ring 9. The magnetic poles here, whether N poles or S poles, are good enough to generate corresponding magnetic group force after magnetic attraction with the magnetic block 4. In addition, the magnetic block 4 is low in cost and easy to obtain, thus meeting the needs of mass production of enterprises.
[0031] Specifically, the twenty-four magnetic poles are arranged at equal angles on the circumference of the multipolar magnetic ring 9, and the angle between the centers of two adjacent magnetic poles and the radius of the line connecting the center of the roller 3 is the magnetic angle; when the multipolar magnetic ring 9 rotates with the roller 3, each magnetic pole on the multipolar magnetic ring 9 and the magnetic block 4 on the bottom plate will approach, face and leave in turn, and the magnetic attraction between the magnetic poles 9 of the multipolar magnetic ring and the magnetic block 4 will generate a magnetic damping force, which will attenuate the rotational kinetic energy of the roller and form resistance to the rotation of the roller 3. The peak value of the magnetic damping force is generated when the magnetic poles are facing the magnetic block 4, and the valley value of the magnetic damping force occurs when the multipolar magnetic ring rotates to the position facing the magnetic block 4 in the non-magnetic area between the two magnetic poles. Every time the multipolar magnetic ring rotates a magnetic angle, the magnetic damping force will change from peak to valley and then to peak, so that the user can clearly feel the rolling state of the roller.
[0032] Of course, the number of magnetic poles can also be 28, 32 or more than 32. This increases the corresponding number of poles, and a large number of poles can improve the fineness of the rotation of the roller 3 by one pole, which improves the fineness of the scrolling on the computer screen.
[0033] Furthermore, a leather cover 6 is provided on the outer circle of the roller 3. When the leather cover 6 is provided on the outer circle of the roller 3, it protects the multi-polar magnetic ring 9 and the user's fingers and increases the friction of the fingers, thereby further improving the customer's user experience.
[0034] Furthermore, a shaft sleeve 7 is provided at the center of the roller 3, a metal shaft 8 is installed in the shaft sleeve 7, and the roller 3 is fixed to the two roller brackets 2 through the shaft sleeve 7 and the metal shaft 8. The above installation method is convenient for assembly and disassembly and easy to use.
[0035] As a further preferred embodiment of the present application, a Hall sensor 5 is further provided on the base plate 1, and the Hall sensor 5 is arranged on the opposite side of the magnetic block 4; the detection center of the Hall sensor 5 is located on the central circumference line of the circumferential surface of the roller 3, for sensing the rotation angle of the roller 3.
[0036] Specifically, when the scroll wheel 3 rotates, when any one of the magnetic poles on the multipolar magnetic ring 9 rotates to a position facing the Hall sensor 5, the magnetic pole on the multipolar magnetic ring 9 is closest to the Hall sensor 5 at this time, and the magnetic induction intensity sensed by the Hall sensor 5 is the largest, exceeding its working point, and the output is turned on, and the output changes from high to low; when the multipolar magnetic ring 9 rotates to a position facing the Hall sensor 5 between two adjacent magnetic poles, the magnetic induction intensity weakens and falls below the release point, and the output is turned off, and the output changes from low to high; when the next magnetic pole rotates to face the Hall sensor 5, its output level changes from high to low again, so that it is sensed that the scroll wheel 3 has rotated a magnetic angle, thereby facilitating corresponding control of the mouse.
[0037] In summary, in the multi-pole magnetic ring mouse scroll wheel of the present invention, when the user is actually using it, the magnetic attraction between the magnetic poles on the multi-pole magnetic ring and the magnetic block is constantly changing while the user is sliding the scroll wheel. The above changes allow the user to feel the damping effect, and the user experience is good. At the same time, the Hall sensor can accurately sense the rotation angle of the scroll wheel, which is convenient for actual use and meets the actual needs of the user.
[0038] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above 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.
