Description

Technical Field

[0001] This application relates to the field of mouse device technology, specifically a novel high-speed side wheel mouse and high-speed side wheel assembly. Background Technology

[0002] With the development of mouse technology, function buttons have been added to mice, enabling users to operate with a single button and eliminating the hassle of using multiple button combinations, thus improving user efficiency. Nowadays, there are even mice with side scroll wheels, positioned to correspond to the user's thumb position, meeting their specific operational needs.

[0003] In the prior art, such as the input device and mouse disclosed in patent application number 201620087192.9, and the magnetic induction side scroll wheel assembly and mouse disclosed in patent application number 202222599952.2, the side scroll wheel has a small central shaft that is connected to the retaining hole of the support arm on the mouse shell by snapping. Because the central shaft of this type of side scroll wheel is relatively small, users need to apply both flicking force and pressing pressure during operation, resulting in a short service life. Furthermore, when assembling the central shaft of the side scroll wheel with the retaining hole of the support arm, the central shaft needs to pass through the anti-disengagement inlet at the front end before it can fall into the final retaining hole. This connection method easily leads to deformation or breakage of the central shaft and support arm, rendering them unusable. Deformation of the central shaft can also cause eccentric rotation when the side scroll wheel is rotated subsequently, resulting in uneven and inaccurate control. Utility Model Content

[0016] Furthermore, it also includes a second printed circuit board and a power module disposed in the internal cavity of the mouse body; the second printed circuit board is connected to the power module, and the first printed circuit board and the second printed circuit board are connected through wiring terminals.

[0017] This utility model also provides a novel high-speed side wheel assembly, comprising:

[0018] The connecting plate includes a first support plate and a second support plate that are spliced ​​together; both the first support plate and the second support plate are provided with rotating connecting columns on their end faces.

The side roller can rotate relative to the connecting plate. After assembly, the central axes of the two rotating connecting columns and the side roller are collinear, resulting in smoother in-situ rotation of the side roller. This high-speed side-wheel assembly, with its design, can be easily and quickly mounted on the mouse body by abutting the connecting plate against the mounting plate. Furthermore, the assembly process of the high-speed side-wheel assembly avoids the drawbacks of traditional side rollers that require compression during assembly, which can affect the lifespan and quality of the side roller.

[0033] Please refer to Figures 1-7 This embodiment provides a novel high-speed side wheel mouse, comprising:

[0034] Mouse body 1, the inner cavity of the mouse body 1 is provided with a mounting plate 110;

[0035] A connecting plate 2 is attached to the mounting plate 110; the connecting plate 2 includes a first support plate 210 and a second support plate 220 that are spliced ​​together; both the first support plate 210 and the second support plate 220 are provided with rotating connecting columns 215 on their end faces.

[0036] The side roller 3 has a sleeve rotation hole 310 at both ends. When the first mounting plate 210 and the second mounting plate 220 are spliced, the two rotating connecting columns 215 extend into the sleeve rotation hole 310 at both ends of the side roller 3, so that the rotating connecting columns 215 support the side roller 3, and the side roller 3 can rotate relative to the connecting plate 2. The central axes of the two rotating connecting columns 215 and the side roller 3 are collinear.

[0037] The first mounting plate 210 and the second mounting plate 220 are assembled into a whole, which constitutes the connecting plate 2. Before the connecting plate 2 is assembled, the first mounting plate 210 and the second mounting plate 220 are located on the left and right sides of the side roller 3, respectively. The rotating connecting columns 215 of the two are located in the sleeve rotating holes 310 at both ends of the side roller 3. When the first mounting plate 210 and the second mounting plate 220 are assembled, the two rotating connecting columns 215 extend into the sleeve rotating holes 310 at both ends of the side roller 3, so that the rotating connecting columns 215 support the side roller 3. The side roller 3 can rotate relative to the connecting plate 2. After the assembly is completed, the central axes of the two rotating connecting columns 215 and the side roller 3 are collinear, so that the side roller 3 can rotate in place more smoothly.

[0038] This high-speed side wheel assembly, with its structural design, can be easily and quickly mounted on the mouse body 1 by connecting the connecting plate 2 to the mounting plate 110. Furthermore, the assembly process of the high-speed side wheel assembly avoids the drawbacks of traditional side wheels that require squeezing during assembly, which can affect the lifespan and quality of the side wheel.

[0039] Please refer to Figure 5 and Figure 6 The rotating connecting column 215 has an alignment hole 2151 on its end face, and the two sleeve rotating holes 310 of the side roller 3 are each provided with an alignment shaft 311 corresponding to the alignment hole 2151; after the first mounting plate 210 and the second mounting plate 220 are spliced ​​together, the two alignment shafts 311 extend into the two alignment holes 2151 respectively.

[0040] This structure allows the side roller 3 to be mounted on the rotating connecting column 215, resulting in higher structural strength and greater stability in use. It avoids the drawbacks of traditional side rollers that use a thin central shaft, making them prone to breakage and wear, and having a short lifespan.

[0041] Please refer to Figure 6 The side roller 3 includes a cylindrical magnet 320, a rotating shaft 330, and an outer roller 340. The cylindrical magnet 320 and the rotating shaft 330 are both disposed in the inner cavity of the outer roller 340, and there are two rotating shafts 330. The cylindrical magnet 320 is located between the two rotating shafts 330. The sleeve rotation hole 310 is surrounded by the outer roller 340 and the rotating shaft 330. The alignment shaft 311 is disposed on the rotating shaft 330.

[0042] The cylindrical magnet 320 can be cylindrical in shape. While the two rotating shaft posts 330 encapsulate the cylindrical magnet 320, the alignment shaft 311 is also located on the rotating shaft posts 330, forming a fitting rotation hole 310 with the inner wall of the outer roller 340. This ingenious design serves three purposes. The outer wall of the outer roller 340 can be provided with anti-slip textures and decorative ring grooves.

[0043] Please refer to Figures 3-5 Both the first support plate 210 and the second support plate 220 are provided with reinforcing ribs 216, and the two rotating connecting columns 215 are connected to the first support plate 210 and the second support plate 220 through the reinforcing ribs 216.

[0044] The rotating connecting column 215 is mounted in a predetermined position by the reinforcing rib plate 216 to facilitate control of the position of the side scroll wheel 3 relative to the mouse body 1. The reinforcing rib plate 216 has good structural strength, which makes the rotating connecting column 215 highly stable.

[0045] The side scroll wheel 3 is exposed outside the mouse body 1. Users can rotate the side scroll wheel 3 to scroll horizontally on the corresponding webpage or perform other defined operations.

[0046] Please refer to Figure 4 and Figure 5 The first mounting plate 210 is provided with a docking groove 211, and a connecting protrusion 212 is provided in the docking groove 211; the second mounting plate 220 is provided with an alignment part 221 that matches and fills the docking groove 211, and the alignment part 221 is provided with a connecting hole 222 that matches and connects the connecting protrusion 212.

[0047] The first mounting plate 210 and the second mounting plate 220 are connected by this structure. The mating groove 211 and the alignment part 221 are aligned first, and the connecting protrusion 212 and the connecting hole 222 are fastened to complete the integrated splicing of the first mounting plate 210 and the second mounting plate 220.

[0048] Preferably, the opening of the mating groove 211 faces the alignment part 221 on the opposite side, and the direction in which the plate of the alignment part 221 slides into the mating groove 211 is consistent with the length direction of the side roller 3.

[0049] Please refer to Figure 3 and Figure 4 The mounting plate 110 is provided with a positioning protrusion 111, and the connecting plate 2 is provided with a mating hole 230 that matches the positioning protrusion 111.

[0050] This structure improves assembly convenience and the dimensional accuracy of the finished product, thereby enhancing the quality of the mouse.

[0052] The 3D Hall sensor chip 410 is used to collect the rotation information of the cylindrical magnet 320 that rotates with the side roller 3, and the information is sent to the first printed circuit board 4 for signal processing and converted into control commands to realize the corresponding control of the electronic device. The algorithms and software programs used in this process are not the focus of the innovation application and will not be described in detail here.

[0053] The first printed circuit board 4 also includes a first button 420 and a second button 430 for expanding mouse functionality. The first button 420 can be a page forward button, and the second button 430 can be a page backward button.

[0054] After the high-speed side wheel assembly is installed on the mouse body 1, a support plate 5 and an outer cover plate 6 are also provided on the outside of the first printed circuit board 4. The support plate 5 covers the surface of the first printed circuit board 4 to provide protection, and is provided with a pressing part corresponding to the first button 420 and the second button 430. When the mouse body 1 has a light effect function, the support plate 5 can also be used as a light guide plate, and the outer cover plate 6 covers the surface of the support plate 5.

[0055] Please refer to Figure 4 and Figure 7 The 3D Hall sensor chip 410 is a KTH5791 chip. The DVDD, AVDD, and VDDIO terminals of the KTH5791 chip are connected to decoupling capacitors to filter out power supply noise signals and maintain stable power supply to the chip. The KTH5791 chip has reserved TEN, SCL, and SDA terminals for parameter configuration and testing. The TEN terminal is connected to a 5.1KΩ resistor R2 to provide a low level, so that the KTH5791 chip enters normal working state by default upon power-up. The MS terminal of the KTH5791 chip is connected to a 5.1KΩ resistor R3 to control the chip's working mode, so that the KTH5791 chip is in a continuous working state.

The first printed circuit board 4 needs to transmit the control actions it receives to the second printed circuit board through the terminal block cable J1, and then the signal transceiver module on the second printed circuit board transmits the signals to realize the corresponding operation interaction of the electronic device terminal. The power module is used to supply power to the various power modules on the mouse body 1.

[0058] Please refer to Figures 3-6 This utility model also provides a novel high-speed side wheel assembly, comprising:
