Description

Mouse wheel state switching mechanism and mouse

This application claims the priority of 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

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

The mouse is an external input device for computers and an indicator for the vertical and horizontal coordinates of the computer display system. The use of the mouse is to make computer operations easier and faster, replacing the cumbersome keyboard instructions. At present, there is a sense of frustration when the mouse wheel is scrolled to turn pages. When the user wants to turn pages quickly, the scroll wheel rotates slowly each time due to the frustration of the scroll wheel, and the number of turns is small, so the page turning speed is very slow. In recent years, in order to solve the above problems, the market has switched the scroll wheel state by adjusting the lever position, and also switched by turning on and off the radial magnetic field.

Based on the above, the inventors found that: the disadvantage of the scheme of switching the roller state by adjusting the lever position is that in the ratchet mode, the lever is always in contact with the roller, and there is a certain pressure, which will cause friction when the roller rotates, and the roller life is short; the disadvantage of the radial magnetic field on-off scheme 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, and a mouse wheel state switching mechanism is provided, in order to achieve a more practical purpose.

Technical issues

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 that the solution of switching the wheel state by adjusting the lever position in the prior art is not effective in the ratchet mode. The lever is always in contact with the roller and there is a certain amount of pressure, which will generate friction when the roller rotates, and the roller life is short; the disadvantage of the radial magnetic field on-off solution is that in the poleless 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.

Some embodiments of the present application provide a mouse wheel state switching mechanism, including a shell 1, a mounting portion 2 is fixedly connected to one side of the shell 1, a support shaft 3 is rotatably connected to the center of the mounting portion 2 through a bearing, a roller 4 is fixedly connected to the outer periphery of the support shaft 3, a rotating shaft 5 is fixedly connected to the other side of the mounting portion 2, a dial 6 is rotatably connected to the outer periphery of the rotating shaft 5, two parallel guide rods 7 are fixedly connected to the inner walls of the top and bottom of the mounting portion 2, and a telescopic frame 8 is slidably connected between the two guide rods 7.

The plurality of first mounting grooves 41 are equidistantly distributed in a ring shape, and a plurality of first magnets 9 are pressed into the corresponding first mounting grooves 41 by interference fit.

Specifically, the number of the first installation grooves 41 is equal to the number of the first magnets 9 , and a plurality of first magnets 9 are inserted into a plurality of first installation grooves 41 one by one, so as to fix the first magnets 9 on the roller 4 .

3 , a plurality of second mounting grooves 83 are formed on one 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 by interference fit.

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

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 to enter a retracted state as a whole, and the second magnet 10 installed on the moving block 81 will be staggered from the first magnet 9 installed on the roller 4, the suction force will be eliminated, and the sense of frustration when the roller 4 rotates will disappear, which is called the stepless mode.
