Description

Technical Field

[0001] This utility model belongs to the field of mouse technology, and in particular relates to a mouse magnetic levitation scroll wheel module. Background Technology

[0002] As an important input device for computers, the performance of the mouse's scroll wheel module directly affects the user experience.

[0003] Traditional mouse scroll wheel assemblies typically use a support structure. Mechanical friction exists between the support and the bracket during scrolling, which can easily cause wear and tear, leading to problems such as scrolling stuttering and increased noise. Furthermore, traditional scroll wheels rely on springs and other mechanical structures for click reset, resulting in insufficient stability of the click stroke, poor tactile feedback, and spring aging affecting the reliability of the click function. In addition, the complexity of the mechanical structure increases the difficulty and cost of production and assembly. Summary of the Invention

[0004] This utility model provides a mouse magnetic levitation scroll wheel module. Addressing the shortcomings of existing technologies, it combines magnetic levitation technology with a mechanical limiting structure to achieve low-friction scrolling, precise press triggering, and stable operation feel, solving problems such as wear, noise, and unstable press feedback that exist in traditional mechanical scroll wheels.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: it includes a mouse body, a main control board, a button assembly, a micro switch, and a battery. The button assembly is installed on the mouse body. The main control board and the micro switch are both installed inside the mouse body and electrically connected to the battery. A plastic frame is also installed inside the mouse body. A scroll wheel assembly is provided at one end of the plastic frame. The scroll wheel assembly includes a mounting frame. Both ends of the mounting frame are slidably connected to the plastic frame. Annular mounting grooves are provided on both sides of the mounting frame. Magnets are installed inside the two annular mounting grooves.

[0006] Furthermore, the plastic frame is equipped with another set of two magnets, with the upper and lower sets of magnets positioned opposite each other and arranged in a manner where like poles repel each other.

[0007] Furthermore, a set of magnets on the plastic frame is fixed in position, and the magnets on the mounting frame maintain a suspended state due to the repulsion of like poles, thus lifting the mounting frame into the air to achieve levitation.

[0008] Furthermore, one end of the mounting frame is provided with a sliding connector, and circular sliders are fixed on both sides of the sliding connector. The plastic skeleton is provided with a sliding guide at the sliding connector. The sliding guide has grooves on both sides and is fitted around the outer periphery of the circular slider and is slidably connected.

[0009] Furthermore, the sliding connector slides directionally in the groove via a circular slider, ensuring that pressing the roller triggers the roller micro switch, while the groove also limits the vertical displacement travel distance of the sliding connector.

[0010] Furthermore, a pressing block is provided at the other end of the mounting frame, a limiting bridge is provided above the pressing block of the plastic skeleton, and a roller micro switch is installed below the pressing block.

[0011] Furthermore, the limiting bridge restricts the vertical displacement travel distance of the pressing block.

[0012] Furthermore, a roller is mounted on the mounting frame, and an encoder is provided on one side of the roller. The encoder is mounted on the mounting frame and electrically connected to the main control board. The central shafts protruding from both ends of the roller are rotatably connected to the mounting frame and the encoder, respectively.

[0013] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects: 1. In this utility model, the mounting frame is suspended on the plastic skeleton by the repulsive effect of the like poles of the upper and lower sets of magnets, eliminating the contact friction of traditional mechanical bearings. When the roller rotates, it only needs to overcome the air resistance and the small resistance of the encoder, achieving a smoother rolling experience, reducing noise and wear, and extending the service life of the roller module. 2. In this utility model, the circular slider of the sliding connector cooperates with the slide groove, and the limit bridge limits the stroke of the pressing block to ensure accurate vertical displacement when pressing the rolling wheel, and the pressing block reliably triggers the roller micro switch; at the same time, the repulsive force of the magnet provides the rebound force after pressing, so that the rolling wheel automatically resets. Combined with the mechanical limit structure, it ensures that the pressing stroke is consistent each time, the feedback is clear, and the operation feel is improved. 3. In this utility model, the magnetic levitation support replaces the traditional mechanical bearing, reducing the number of mechanical parts, simplifying the structure, and reducing assembly difficulty and cost; at the same time, the non-contact magnetic levitation design avoids the wear problem of mechanical parts and improves the reliability and stability of the roller module.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Combination Figures 1 to 4 The mouse magnetic levitation scroll wheel module shown includes a mouse body 1, a main control board, a button assembly 2, a micro switch 3, and a battery. The button assembly 2 is installed on the mouse body 1. The main control board and the micro switch 3 are both installed inside the mouse body 1 and electrically connected to the battery. A plastic frame 4 is also installed inside the mouse body 1. A scroll wheel assembly 5 is provided at one end of the plastic frame 4. The scroll wheel assembly 5 includes a mounting frame 51. Both ends of the mounting frame 51 are slidably connected to the plastic frame 4. Both sides of the mounting frame 51 are provided with annular mounting grooves 52. Magnets 53 are installed inside the two annular mounting grooves 52.

[0018] Among them, the plastic frame 4 is equipped with another set of two magnets 53, and the upper and lower sets of magnets 53 are positioned opposite each other and arranged in a way that like charges repel each other.

[0019] A set of magnets 53 on the plastic frame 4 are fixed in position. The magnets 53 on the mounting frame 51 maintain a suspended state under the repulsive force of like poles, thus lifting the mounting frame 51 into the air to achieve suspension.

[0020] One end of the mounting frame 51 is provided with a sliding connector 54, and circular sliders 55 are fixed on both sides of the sliding connector 54. The plastic skeleton 4 is provided with a sliding guide 41 at the sliding connector 54. The sliding guide 41 has grooves 42 on both sides and is fitted around the outer periphery of the circular sliders 55 and is slidably connected.

[0021] The sliding connector 54 slides in the groove 42 via the circular slider 55, ensuring that pressing the roller 7 triggers the roller micro switch 6. At the same time, the groove 42 also limits the vertical displacement travel distance of the sliding connector 54.

[0022] The other end of the mounting frame 51 is provided with a pressing block 56. The plastic frame 4 is provided with a limiting bridge 43 above the pressing block 56, and a roller micro switch 6 is installed below the pressing block 56.

[0023] The limiting bridge 43 restricts the vertical displacement travel distance of the pressing block 56.

[0024] A roller 7 is mounted on the mounting frame 51. An encoder 8 is provided on one side of the roller 7. The encoder 8 is mounted on the mounting frame 51 and electrically connected to the main control board. The central shafts protruding at both ends of the roller 7 are rotatably connected to the mounting frame 51 and the encoder 8, respectively.

[0025] Working Principle: During use, when the user presses the scroll wheel 7, the mounting frame 51 moves downward due to the force, causing the circular slider 55 of the sliding connector 54 to slide downward in the groove 42. At the same time, the pressing block 56 moves downward. Below the pressing block 56 is the scroll wheel micro switch 6. When the pressing block 56 contacts and squeezes the scroll wheel micro switch 6, the internal contacts of the switch close, sending a pressing signal to the main control board. Simultaneously, the groove 42 and the limiting bridge 43 respectively limit the vertical displacement stroke of the sliding connector 54 and the pressing block 56, ensuring the accuracy of the pressing stroke and the feedback feel. In the magnetic levitation state, the scroll wheel 7 only needs to overcome the air resistance and the slight resistance of the encoder when rotating. Compared with the traditional mechanical scroll wheel of a mouse, the rotation is smoother, the noise is lower, and wear is reduced, extending the service life. The repulsive force of the magnet 53 also provides a rebound force after pressing, so that the scroll wheel 7 automatically resets after pressing. Combined with the mechanical limiting of the groove 42 and the limiting bridge 43, it ensures that the stroke of each press is consistent, the feedback is clear, and the operation feel is improved.
