Description

Technical Field

[0001] This utility model relates to the field of mice, and in particular to a mouse wheel and mouse that are easy to disassemble. Background Technology

[0002] The mouse wheel is a seemingly simple yet extremely important functional component of modern computer mice. By scrolling up and down the wheel, users can quickly flip through long content such as web pages, documents, spreadsheets, and PDFs. Compared to dragging the scroll bar, this operation is more intuitive and saves time and effort. Using the mouse wheel eliminates the need to move fingers to click the scroll bar; page turning can be completed with just a slight movement of the thumb and forefinger, significantly reducing the operation path and time. Traditional mouse wheels are usually fixed to a bracket inside the mouse by a metal or plastic shaft. One end of the shaft engages with a rotary encoder, while the other end is clipped or fixed to a support base. Dust, hair, and other dirt easily accumulate in the gaps of the mouse wheel, affecting the smoothness of scrolling and the feel over time. Because the scroll wheel cannot be easily disassembled, it is difficult for users to clean it thoroughly.

[0003] Traditional mouse scroll wheels are inconvenient to disassemble and clean. Therefore, this paper provides a mouse scroll wheel and mouse that are easy to disassemble. Utility Model Content

[0004] The main purpose of this utility model is to provide a mouse wheel and mouse that are easy to disassemble, so as to solve the problem in the related art that traditional mouse wheels are inconvenient to disassemble and difficult to clean when using them.

[0019] This embodiment provides a mouse scroll wheel that is easy to disassemble, including a mounting groove 11 inside the mouse housing 1 and a mounting part 2 inside the mounting groove 11, wherein the mounting part 2 is snapped onto the scroll wheel 22. It also includes: a limiting part 3, which is slidably installed inside the mouse housing 1. The limiting part 3 includes at least a connecting rod 31. A pin 311 is fixedly installed on one side of the connecting rod 31. The limiting part 3 also includes a pushing part. When the pushing part is pressed manually, the connecting rod 31 and the pin 311 on it are moved and pass through the mounting part 2 to press against the side wall of the roller 22, thus limiting the roller 22 and installing it on the mounting part 2. When the pushing part is released, the connecting rod 31 and the pin 311 on it are reversed and reset, thus releasing the limitation on the roller 22. like Figure 2 , Figure 3 , Figure 4 As shown, the mounting slot 11 has a telescopic groove 12 on its side wall, and the mouse shell 1 has a pressing groove 13 on its side wall. The inner side wall of the pressing groove 13 has a connecting groove 131 that connects to the telescopic groove 12. The mouse front cover 111 is snapped into place at the opening of the mounting slot 11. The mouse front cover 111 has a scroll wheel groove 112 through its middle. One end of the scroll wheel 22 passes through the scroll wheel groove 112 and is exposed to the outside. The mounting slot 11 has a slot on its side wall, and the mouse front cover 111 has a locking block fixedly installed on its side wall. The mouse front cover 111 is installed on the mouse shell 1 by the interference fit between the locking block and the slot. Conversely, it can be removed by manually prying it out. Before removing the scroll wheel 22, pull the mouse front cover 111 outward from the scroll wheel groove 112 to disengage the locking block from the slot and open the mouse front cover 111. like Figure 1 , Figure 2 , Figure 6 As shown, the mounting part 2 includes a mounting frame 21. One end of the mounting frame 21 is provided with a support groove 211. The support groove 211 has a U-shaped structure. The side wall of the mounting frame 21 is provided with a limiting hole 212 that communicates with the support groove 211. like Figure 5 , Figure 6 As shown, the other end of the mounting bracket 21 is provided with a rotating groove 213, and a positioning shaft 214 is rotatably mounted in the rotating groove 213. The side wall of the positioning shaft 214 is provided with a drive insertion hole 215, which is a regular hexagonal structure. like Figure 7 As shown, a mounting shaft 221 is rotatably mounted on one side wall of the roller 22, and a drive shaft 223 is fixedly mounted on the other side wall of the roller 22. Several grooves 222 are provided on the side wall of the mounting shaft 221. A U-shaped support groove 211 clamps the mounting shaft 221 of the roller 22 from one side, providing radial support. The limiting hole 212 serves as a mechanical locking channel. The insertion shaft 311 is inserted into the groove 222 to prevent the roller 22 from moving axially. The opening of the support groove 211 faces upward, which facilitates the vertical insertion of the mounting shaft 221 and reduces the assembly difficulty.

[0020] like Figure 5 As shown, in order to ensure that the roller 22 effectively drives the rotary encoder, the mounting shaft 221 is snapped into the support groove 211. The drive shaft 223 is a regular hexagonal structure that is adapted to the drive socket 215. The drive shaft 223 is inserted into the drive socket 215, and the rotary encoder is fixedly installed in the drive socket 215. After the drive shaft 223 is inserted into the drive socket 215, due to the hexagonal fit, it is ensured that the roller 22 can effectively drive the encoder when it rotates. The encoder is fixed to the bottom of the drive socket 215. When the roller 22 rotates, it directly drives the encoder shaft to rotate and outputs a pulse signal.

[0021] like Figure 3 , Figure 8As shown, one end of the insert shaft 311 passes through the limiting hole 212 and is located in the groove 222. A compression spring 313 is fixedly installed on the other side of the connecting rod 31. The other end of the compression spring 313 is fixedly installed on the inner side wall of the telescopic groove 12. During installation, the roller 22 is placed into the support groove 211, and the drive shaft 223 is inserted into the drive insertion hole 215. The groove 222 is used to cooperate with the insert shaft 311 of the limiting part 3 to achieve axial locking. The compression spring 313 pushes the connecting rod 31, so that the insert shaft 311 is embedded in the groove 222 of the roller 22 to achieve axial locking. The compression spring 313 provides a constant preload to prevent vibration and loosening. like Figure 8 As shown, an adjustment slot 312 is provided through the side wall of the connecting rod 31. The adjustment slot 312 is an inclined slot that is inclined towards the mounting slot 11. like Figure 8 As shown, the pushing part includes a rod 32, which is slidably installed in the connecting groove 131. One end of the rod 32 is provided with an angle that matches the adjustment slot 312, and the other end of the rod 32 is inserted into the adjustment slot 312.

[0022] like Figure 3 As shown, a button 321 is fixedly installed on one side of the insertion rod 32. The button 321 is slidably installed in the pressing groove 13. Two return springs 322 are fixedly installed on the side wall of the button 321. The other end of the return springs 322 is fixedly installed on the inner side wall of the pressing groove 13. When the roller 22 is removed, the external button 321 is pressed, and the insertion rod 32 moves into the connecting groove 131. The angle of the insertion rod 32 presses the adjustment slot 312, and the adjustment slot 312 drives the connecting rod 31 to move laterally. The insertion shaft 311 exits the groove 222, and the roller 22 can be removed and installed. At step 2, align the drive shaft 223 with the drive insertion hole 215 and insert it. Align the mounting shaft 221 of the roller 22 with the support groove 211 and press the mounting shaft 221 into the bottom of the support groove 211. Under the action of the compression spring 313, the limiting part 3 will insert the shaft 311 into the groove 222, thus completing the installation of the roller 22. Users can easily disassemble and assemble the roller 22. The whole process can be completed in a few seconds without any tools. Users can remove the roller 22 by hand at any time and clean it thoroughly, completely solving the problem of dirt accumulation. When the scroll wheel 22 is damaged, a new scroll wheel 22 component can be purchased directly for replacement, greatly reducing maintenance difficulty and cost. Manufacturers can launch scroll wheel 22 components of different materials, colors, and surface textures as accessories for sale. Users can change the mouse scroll wheel 22 at will according to their own feel preferences and aesthetic needs, just like changing a phone case, increasing the playability and added value of the product. The scroll wheel 22 is locked by the limiting part 3, ensuring that the stability of the scroll wheel 22 in the working state is no less than that of the traditional fixed structure, eliminating shaking and play, and ensuring the operation feel and the accuracy of the encoder signal.
