Description

Mouse wheel state switching mechanism and mouse

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on September 2, 2023, with application number 202322376704.6 and invention name “A mouse wheel state switching mechanism”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of mouse technology, and in particular to a mouse wheel state switching mechanism and a mouse. Background Art

[0003] A mouse is an external input device for computers and an indicator of the vertical and horizontal coordinates of a computer display system. It's used to make computer operations simpler and faster, replacing the cumbersome keyboard instructions. Currently, mouse scroll wheels experience a jerky feeling when turning pages. When users want to turn pages quickly, this jerky feeling causes the wheel to rotate slowly and infrequently, resulting in slow page turning. To address this issue, new devices have emerged in recent years, some of which switch the scroll wheel state by adjusting the lever position, while others switch by turning the radial magnetic field on and off.

[0004] Based on the above, the inventors found that: the disadvantage of the solution of switching the scroll wheel state by adjusting the lever position is that in the ratchet mode, the lever is always in contact with the scroll wheel, and there is a certain pressure, which will cause friction when the scroll wheel rotates, and the roller life is short; the disadvantage of the radial magnetic field on-off solution is that in the stepless mode, power needs to be turned on to generate a magnetic field to offset the magnetic field of the magnet, the circuit is complex and the cost is high. Therefore, in view of this, the existing structure is studied and improved to provide a mouse scroll wheel state switching mechanism, in order to achieve a more practical purpose. Technical issues

[0005] One of the purposes of the embodiments of the present application is to provide a mouse wheel state switching mechanism and a mouse to solve the problem in the prior art of switching the wheel state by adjusting the lever position. In the ratchet mode, the lever is always in contact with the wheel and there is a certain pressure, which will cause friction when the wheel rotates and shorten the life of the wheel. The disadvantage of the radial magnetic field on-off solution is that in the stepless mode, power needs to be turned on to generate a magnetic field to offset the magnetic field of the magnet, and the circuit is complex and the cost is high.

[0020] The beneficial effect of the mouse wheel state switching mechanism provided in the embodiment of the present application is that: by controlling the dial, the telescopic frame equipped with the second magnet can be made to move back and forth horizontally along the guide rod. When it is opposite to the first magnet, a certain attraction or repulsion will be generated, so that there will be a sense of frustration when the wheel is rotated, which is the ratchet mode. When they are staggered, the attraction or repulsion is eliminated, so that the sense of frustration when the wheel is rotated disappears, which is the stepless mode. The switching between the ratchet and stepless modes is achieved by changing the position of the second magnet, thereby simultaneously meeting the characteristics of long service life and low power consumption.

[0021] The beneficial effect of the mouse provided by the embodiment of the present application is that: the mouse wheel state switching mechanism provided by the embodiment of the present application is adopted, and the mouse wheel state switching mechanism can use the dial to realize the horizontal reciprocating movement of the telescopic frame equipped with the second magnet along the guide rod.

[0034] In order to illustrate the technical solution provided by this application, a detailed description is given below with reference to specific drawings and embodiments.

[0035] Referring to Figures 1-4, some embodiments of the present application provide a mouse wheel state switching mechanism, comprising a housing 1, a mounting portion 2 fixedly connected to one side of the housing 1, a support shaft 3 rotatably connected to the center of the mounting portion 2 via a bearing, a roller 4 fixedly connected to the periphery of the support shaft 3, a rotating shaft 5 fixedly connected to the other side of the mounting portion 2, a dial 6 rotatably connected to the periphery of the rotating shaft 5, two parallel guide rods 7 fixedly connected to the top and bottom inner walls of the mounting portion 2, a telescopic frame 8 slidably connected between the two guide rods 7, The dial 6 is engaged with the telescopic frame 8, and a plurality of first magnets 9 and second magnets 10 are respectively provided on the side where the roller 4 and the telescopic frame 8 are close to each other. When in use, the dial 6 can be controlled to make the telescopic frame 8 equipped with the second magnet 10 perform horizontal reciprocating motion along the guide rod 7. When it is opposite to the first magnet 9, a certain suction force is generated, or the second magnet 10 and the first magnet 9 generate a certain repulsive force, so that there is a sense of frustration when the roller 4 is rotated, which is the ratchet mode. When they are staggered, the suction force is eliminated, or the repulsive force is eliminated, so that the sense of frustration when the roller 4 is rotated disappears, which is the stepless mode. By changing the relative position of the second magnet 10 and the first magnet 9 in this way, the ratchet and stepless modes of the mouse can be quickly switched, which reduces the friction generated when the roller 4 rotates and the consumption of electricity, thereby meeting the characteristics of long service life and low power consumption.

[0036] Optionally, the magnetic poles of the first magnet 9 are opposite to those of the second magnet 10, so that when the second magnet 10 is opposite to the first magnet 9, a certain attraction force is generated. Alternatively, the magnetic poles of the first magnet 9 are the same as those of the second magnet 10, so that when the second magnet 10 is opposite to the first magnet 9, a certain repulsion force is generated.

[0037] Referring to Figure 4, the telescopic frame 8 includes two moving blocks 81 slidably sleeved on the outer periphery of the guide rod 7. The two moving blocks 81 are arranged symmetrically with respect to the center, and a toggle column 82 is fixedly connected to the same side. When in use, through the setting of the toggle column 82, when the dial 6 is toggled, the two moving blocks 81 can be controlled to move in opposite directions. With the cooperation of the first magnet 9 and the second magnet 10, the ratchet mode and the stepless mode of the mouse can be quickly switched.

[0038] 4 , a slot 61 is provided at the position of the dial 6 corresponding to the toggle post 82 , and the slot 61 is engaged with the outer periphery of the corresponding toggle post 82 . When in use, the slot 61 facilitates the connection between the dial 6 and the telescopic frame 8 .

[0039] Specifically, the length of the slot 61 extends along the radial direction of the dial 6. When the dial 6 is turned, the turning column 82 moves relatively in the slot 61 along the length extension direction of the slot 61 to drive the two moving blocks 81 to move in opposite directions or toward each other, so that the second magnet 10 is opposite to or staggered with the first magnet 9.

[0040] 1 and 2 , a limiting hole is provided on one side of the housing 1 , and the dial 6 is disposed in the limiting hole. When in use, the limiting hole facilitates the movement of the dial 6 .

[0041] 2 , a plurality of first mounting grooves 41 are formed on one side of the roller 4 close to the telescopic frame 8 . The plurality of first mounting grooves 41 are equidistantly distributed in a circular pattern, and a plurality of first magnets 9 are pressed into the corresponding first mounting grooves 41 by interference fit.

[0042] Specifically, the number of the first mounting grooves 41 is equal to the number of the first magnets 9 , and the first magnets 9 are respectively inserted into the first mounting grooves 41 one by one, thereby fixing the first magnets 9 on the roller 4 .

[0043] 3 , a plurality of second mounting grooves 83 are formed on a side of the moving block 81 close to the roller 4 , and a plurality of second magnets 10 are pressed into the corresponding second mounting grooves 83 through interference fit.

[0044] Specifically, the number of the second mounting slots 83 is equal to the number of the second magnets 10 , and the second magnets 10 are respectively inserted into the second mounting slots 83 to fix the second magnets 10 on the moving block 81 .

[0045] 1 and 2 , the outer ring fixing sleeve of the roller 4 is provided with an anti-slip sleeve 11 .

[0046] When in use: when the dial 6 is turned clockwise by a certain angle, the dial 6 drives the two moving blocks 81 to move away from each other, so that the telescopic frame 8 is in an extended state as a whole, and the second magnet 10 installed on the moving block 81 is just opposite to the first magnet 9 installed on the roller 4, which will generate a certain suction force, so there will be a sense of frustration when the roller 4 is rotated, which is called the ratchet mode; when the dial 6 is turned counterclockwise by a certain angle, it will drive the telescopic frame 8 as a whole into a retracted state, and the second magnet 10 installed on the moving block 81 is staggered with the first magnet 9 installed on the roller 4, the suction force is eliminated, and the sense of frustration when the roller 4 rotates disappears, which is called the stepless mode. The ratchet and stepless modes achieve fast switching by changing the relative position of the second magnet 10 and the first magnet 9, which reduces the friction generated when the roller 4 rotates and the overall power consumption, while meeting the characteristics of long service life and low power consumption.

[0047] An embodiment of the present application also provides a mouse, comprising the mouse wheel state switching mechanism of any of the above embodiments.

[0048] The above are merely optional embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included within the scope of the claims of the present application.
