Abstract
Description
Technical Field
[0001] This application relates to the field of trackball mouse technology, and in particular to a trackball mouse that is easy to clean. Background Technology
[0002] A trackball mouse is a type of mouse whose biggest advantage is that it doesn't move around as much as a mechanical mouse, saving space and reducing wrist fatigue. Compared to a regular mouse, a trackball, due to its design features, offers precise positioning and is less prone to wobbling, making it suitable for graphic design, 3D design, and other similar tasks.
[0003] Currently, the trackball in a trackball mouse is connected to the bottom shell via a bracket. The trackball is embedded in the bracket, which is connected to the bottom shell. When the trackball needs to be cleaned, maintained, or replaced, the outer shell must be removed first, and then the bracket must be removed from the base before the trackball can be removed. During installation, the bracket and optical sensing components must be precisely positioned and connected; otherwise, the trackball trajectory cannot be accurately read, which is very inconvenient. Utility Model Content

[0020] like Figures 1 to 6 As shown, one embodiment of this utility model provides an easy-to-clean trackball mouse, including a trackball assembly 1000. The trackball assembly 1000 includes a hemispherical support 1100, a circuit receiving cavity 1200 at the bottom of the hemispherical support 1100, and an optical sensing component 1300 installed within the circuit receiving cavity 1200. A ball receiving cavity 1400 is provided on the outer periphery of the hemispherical support 1100, and through holes are provided on opposite sides of the ball receiving cavity 1400. An adjusting ball 1500 is installed in one of the through holes communicating with the interior of the hemispherical bracket 1100. A track ball 1600 and a dustproof ring 1700 are installed inside the hemispherical bracket 1100. A vertical rib 1710 is provided on the lower surface of the dustproof ring 1700. The dustproof ring 1700 is fastened to the upper surface of the hemispherical bracket 1100, and the vertical rib 1710 is inserted into the ball receiving cavity 1400 and abuts against the adjusting ball 1500, thereby limiting the movement of the track ball 1600 and the adjusting ball 1500.
[0021] The hemispherical bracket 1100 provides a mounting cavity for the trackball 1600, which is mounted in the mounting cavity. The outer wall of the trackball 1600 is rotatably connected to the adjusting ball 1500 in the ball receiving cavity 1400, but not directly connected to the hemispherical bracket 1100. The bottom of the hemispherical bracket 1100 is provided with a circuit receiving cavity 1200. The optical sensing component 1300 in the circuit receiving cavity 1200 is used to illuminate the trackball 1600 with a sensing fiber to determine the movement trajectory of the trackball 1600. The dustproof ring 1700 is fastened to the upper surface of the hemispherical bracket 1100, and the vertical rib 1710 on its lower surface is inserted into the ball receiving cavity 1400 and abuts against the adjusting ball 1500 without hindering the rotation of the adjusting ball 1500. The dustproof ring 1700 limits the trackball 1600 and the adjusting ball 1500 to prevent them from coming out. The trackball 1600 is fixed inside the hemispherical bracket 1100 by the dustproof ring 1700. After removing the dustproof ring 1700, the trackball 1600 can be removed, which is convenient for cleaning, maintenance or replacement of the trackball 1600. At the same time, the adjusting ball 1500 is installed and fixed through the ball receiving cavity 1400 and the vertical bone 1710, which is convenient for disassembly and maintenance.
[0022] As one embodiment of this utility model, please refer to Figure 1 and Figure 2 The trackball mouse also includes a base 2000 and a shell 5000. The lower surface of the base 2000 is connected to the device via a connector assembly. A circuit board 3000 is mounted on the upper surface of the base 2000. The circuit board 3000 is electrically connected to the optical sensing assembly 1300 of the trackball assembly 1000, the connector assembly, and the scroll wheel button assembly 4000. The scroll wheel button assembly 4000 is located on one side of the circuit board 3000. The lower part of the shell 5000 is detachably connected to the base 2000, covering the entire circuit board 3000 and parts of the trackball assembly 1000 and the scroll wheel button assembly 4000, thus preventing components from being exposed and providing a grip surface.
[0023] As one embodiment of this utility model, please refer to Figure 1 and Figure 2 The outer casing 5000, trackball 1600, and scroll wheel button assembly 4000 are provided with trackball holes and scroll wheel button holes at corresponding positions.
[0024] As one embodiment of this utility model, please refer to Figure 3 , Figure 4 and Figure 6A retaining ring is fixedly connected to the upper part of the hemispherical bracket 1100 around the mounting cavity. The ball bearing accommodating cavity 1400 is spaced on the retaining ring. The retaining ring is also spaced on the retaining ring. A buckle 1720 is provided on the lower surface of the dustproof ring 1700 at the position corresponding to the buckle hole. The buckle 1720 engages in the buckle hole to connect the dustproof ring 1700 and the hemispherical bracket 1100 into a whole.
[0025] As one embodiment of this utility model, please refer to Figure 4 and Figure 5 The through holes include a first through hole 1800 and a second through hole 1900, which are arranged opposite to each other. The first through hole 1800 is hemispherical, with one end connected to the inner side of the hemispherical bracket 1100 and the other side connected to the ball bearing cavity 1400. The adjusting ball 1500 can extend into the mounting cavity through the first through hole 1800. The second through hole 1900 is equipped with a detachable buckle plate to facilitate viewing and moving the adjusting ball 1500.
[0026] As one embodiment of this utility model, please refer to Figure 6 The cross-section of the vertical bone 1710 is T-shaped, and its end has an arc-shaped structure, which facilitates the insertion of the adjusting ball 1500 into the first through hole 1800 during the insertion of the ball receiving cavity 1400.
[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0028] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
