Description

Technical Field

[0001] This disclosure relates to the field of cursor input device technology, and more particularly to a detachable and washable vibration-resistant trackball. Background Technology

[0002] A trackball is an input device used for precise cursor control, primarily in scenarios requiring high-precision operation or prolonged use. Its core function is to achieve positioning by directly manipulating the ball with the fingers or thumb, reducing wrist movement and improving operational efficiency compared to a traditional mouse. However, the trackball's control ball is directly exposed and in frequent contact with fingers, easily absorbing skin oils, sweat, and environmental dust. This mixture of dust and oil forms a sticky layer on the trackball's surface, which can also penetrate the internal sensor area, increasing rolling resistance and even affecting photoelectric signal recognition, thus reducing sensitivity. Furthermore, as precise cursor control is required, vibration resistance is essential. In environments with vibrations, such as those involving vehicles or aircraft, vibration resistance is crucial. Existing vibration-resistant trackballs are difficult to disassemble and clean, as disassembly can easily scatter the vibration-resistant components, requiring reassembly, which is time-consuming and labor-intensive. Therefore, trackball cursor input devices need optimization and improvement to achieve both vibration resistance and ease of disassembly and cleaning, thus meeting usage requirements. Utility Model Content

[0003] In view of this, this disclosure proposes a detachable and washable anti-vibration trackball, which solves the technical problems of existing anti-vibration trackball products being non-removable and washable, or difficult to reassemble after disassembly.

[0004] According to one aspect of this disclosure, a removable and washable vibration-resistant trackball is provided, comprising:

[0005] The main housing has an upper cavity and a lower cavity. The bottom of the upper cavity has a light inlet, and the outer edge of the main housing has a first connecting ear.

[0006] A fixing seat is embedded in the upper cavity. The fixing seat has a supporting cavity. A first circular through hole is provided at the bottom center of the supporting cavity. The light inlet is located inside the hole of the first circular through hole.

[0007] A trajectory sphere, which is placed on the support cavity of the fixed base;

[0008] An anti-vibration cover assembly includes an upper cover body, a movable pressure ring, and a fixed pressure ring. The upper cover body has a recessed cavity with a second through hole in the center. The fixed pressure ring is positioned above the recessed cavity and connected by screws. The movable pressure ring is positioned between the fixed pressure ring and the recessed cavity. Multiple compression springs are evenly distributed along the edge of the movable pressure ring, which elastically abut against the bottom of the fixed pressure ring. The movable pressure ring elastically presses against the track ball. A second connecting ear is provided on the outer edge of the upper cover body, and the second connecting ear is fixedly connected to the first connecting ear by screws.

[0009] The lens and circuit board are provided, and the lower cavity has a slot for mounting the lens at the light inlet, and the circuit board is fixed in the lower cavity.

[0010] A bottom cover is provided on the bottom of the lower cavity of the main housing.

[0011] Furthermore, the inner edge of the upper port of the support cavity of the fixed seat is set as a chamfered arc edge, and at least three first notches are evenly arranged on the chamfered arc edge. Each first notch is provided with a first contact ball, and the first contact ball is in contact with the track ball.

[0012] Furthermore, the movable pressure ring includes a circular ring body. The lower outer wall of the circular ring body is provided with a vertically outwardly extending convex edge. The convex edge is provided with a plurality of through holes evenly distributed. A compression spring is arranged in each through hole. The upper inner wall of the circular ring body is provided with an inwardly expanding sloping inner wall. The sloping inner wall is used to tightly press against the track sphere. The bottom of the fixed pressure ring is provided with a series of insertion posts that are inserted into the compression springs and through holes.

[0013] Furthermore, the annular body is uniformly provided with at least three second notches along the inner wall of the slope, and each second notch is provided with a second contact bead, which is in contact with the trajectory sphere.

[0014] Furthermore, the bottom of the fixed pressure ring is evenly provided with at least three barbs, which are inserted from the outside of the protruding edge of the movable pressure ring, so that when the fixed pressure ring is removed from the upper cover, the barbs hook the movable pressure ring.

[0015] Preferably, both the first contact bead and the second contact bead are made of zirconium oxide beads.

[0016] Furthermore, the lower port edge of the lower cavity of the main housing is provided with a sealing groove, and a waterproof rib is provided in the sealing groove. The bottom of the bottom cover is provided with a sealing protrusion that is inserted into the sealing groove. The sealing protrusion presses against the waterproof rib. A screw connection position is provided on the outside of the sealing groove. A screw hole position corresponding to the screw connection position is provided on the outside of the sealing protrusion of the bottom cover.

[0017] Furthermore, the side wall of the recessed cavity of the upper cover is provided with a limiting horizontal baffle, which is used to lock and limit the connection when the fixing ring is connected and fixed to the recessed cavity.

[0018] The advantages of the detachable and washable vibration-resistant trackball disclosed in this solution are as follows: This solution optimizes the design of the vibration-resistant cover assembly, allowing it to be disassembled as a single unit, enabling the removal of the trackball for cleaning. This integrated design avoids the time-consuming and laborious process of disassembling and reassembling the cover assembly piece by piece when removing the trackball. After cleaning the trackball and vibration-resistant cover assembly, the trackball is placed in the support cavity of the mounting base, and the vibration-resistant cover assembly is then fixed to the main housing with screws. This design achieves both convenient disassembly and cleaning while providing vibration-resistant functionality, making it suitable for use in environments subject to vibration. The vibration-resistant structure utilizes a compression spring connected to a fixed pressure ring. The compression spring abuts against the movable pressure ring, allowing the elastic potential energy of the spring to counteract the energy generated by the trackball's vibration when the trackball vibrates, thus achieving a vibration-resistant effect.
