Among them, for a wired mouse, a mouse wire is connected to the mouse, and it is connected to the computer's USB interface through a USB connector, and the connection between the mouse and the mouse wire is a fixed connection. For a wireless mouse, communication between the mouse and the computer is carried out through a wireless USB. The roller device is one of the main devices of the mouse. After the mouse adopts the roller device, the operation of the computer page is greatly simplified. The mouse encoder is a sensor that converts the angular displacement of the mouse roller into an electrical signal. Generally, mechanical encoders and grating encoders are used in the encoder of the mouse roller device. The structure of the grating encoder is complex and the manufacturing cost is high. The mouse equipped with the grating encoder requires special main control programming and is basically assembled in high-priced gaming mice; the traditional mechanical encoder has a simple structure and a low manufacturing cost, and the main control programming of the mouse equipped with the traditional mechanical encoder is simple and is widely used in the mouse industry. At present, on the market, a double-layer circuit board is required to fix the encoder for a mouse with an ultra-high roller. After long-term use, the coding signal processing circuit board is prone to wear, resulting in a decrease in mouse sensitivity or even inability to use, and the circuit board needs to be replaced, greatly increasing the cost of the manufacturer.

Detailed implementation manners

[0019] The following will make a specific and detailed description of the implementation manners of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.

[0020] Combined with Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a mouse encoder mounting structure includes a base 1 and an upper cover 2. A circuit board 3 is mounted on the base 1. A left button 4 and a right button 5 are connected to the circuit board 3 by soldering. An installation seat 6 is provided on the base 1. A roller 7 is provided at the top of the installation seat 6. One end of the rotating shaft of the roller 7 is electrically connected to the circuit board 3, and the other end of the rotating shaft of the roller 7 is fixedly connected to a fixed encoder 8. The center of the fixed encoder 8 is at the same height as the rotation axis of the roller 7. Specifically, for a mouse encoder mounting structure, the base 1 is made of a high-strength lightweight alloy material, which not only ensures the structural stability but also effectively reduces the overall weight, making it convenient for long-term use without fatigue. The surface of the base 1 is finely sandblasted to increase the friction when holding and prevent slipping. The upper cover 2 is made of high-quality ABS plastic or acrylic material. The upper cover 2 and the base 1 are connected by a precise double fixing method of snap and screw to ensure sealing and stability. The circuit board 3 uses a high-integration, low-power microcontroller (MCU) as the core, and is combined with high-precision resistive or capacitive touch sensors to achieve precise recognition and rapid response of the left button 4 and the right button 5. The surface of the circuit board 3 is covered with an anti-static and scratch-resistant protective coating to extend the service life. The left button 4 and the right button 5 adopt an ergonomic design, with a moderate key stroke, a soft touch and a clear feedback, reducing finger fatigue caused by long-term clicking. Some high-end versions also support custom button functions to meet the usage habits of different users. The roller 7 uses a steel axis wrapped with high-quality rubber, with smooth and silent rolling. The surface of the roller 7 is designed with anti-slip textures to increase the control feeling when rolling. A precise bearing structure is provided under the roller 7 to ensure smooth and unobstructed movement after long-term use. As a key component for converting the rotation signal of the roller 7 into an electrical signal, the center of the fixed encoder 8 is precisely aligned with the rotation axis of the roller 7 and is on the same horizontal plane, ensuring the accuracy and stability of data transmission. The fixed encoder 8 uses high-precision optoelectronic or magnetic induction technology, which can capture every subtle rotation of the roller to achieve precise cursor movement or page scrolling.

[0021] Combined Figure 3 and Figure 4As shown, the mounting base 6 is in a cuboid structure. A first groove 61 is provided at the top of the mounting base 6. U-shaped grooves 62 are provided on both sides of the first groove 61. The rotating shaft of the roller 7 can rotate within the U-shaped grooves 62. A second groove 63 is provided on one side of the first groove 61. The first groove 61 and the second groove 63 are fixedly communicated through the U-shaped grooves 62. The fixed encoder 8 is fixedly installed within the second groove 63. The rotating shaft of the roller 7 penetrates through the U-shaped grooves 62 and is fixedly connected to the fixed encoder 8. Specifically, the mounting base 6 adopts a cuboid structure. This structure is not only easy to process and manufacture but also can provide a stable support surface to ensure the precise operation of the roller and the encoder. A first groove 61 is provided at the top of the mounting base 6, and U-shaped grooves 62 are provided on both sides of the first groove 61. These two U-shaped grooves 62 not only provide sufficient space for the rotating shaft of the roller 7 to move but also effectively limit the lateral movement of the rotating shaft through their unique shape design, ensuring the stability and precision of the roller 7 during rotation. Further, a second groove 63 extends from one side of the first groove 61, achieving the fixed communication between the first groove and the second groove. This not only simplifies the installation process but also enables the rotating shaft of the roller 7 to smoothly pass through the U-shaped grooves 62 and finally be fixedly connected to the fixed encoder 8 installed within the second groove 63. This ensures both the flexibility of the rotation of the roller 7 and the ability of the fixed encoder 8 to accurately capture and convert the rotation signal of the roller. The fixed encoder 8 is installed within the second groove 63. The center of the fixed encoder 8 is aligned with the rotation axis of the roller 7, thereby maximizing the accuracy and efficiency of signal conversion.

[0022] Combined with Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, one end of the circuit board 3 is provided with a USB connection port 9. Specifically, the USB connection port 9, as a bridge between the circuit board and external devices (such as a computer), adopts the widely used USB standard interface. The USB connection port 9 is arranged at one end of the circuit board 3, which not only ensures the easy accessibility of the USB connection port 9 but also avoids spatial conflicts with other internal components. In addition, the insulation and protection design around the USB connection port 9 is strengthened to prevent damage to the interface caused by external factors such as static electricity and dust, thereby ensuring the stability and security of data transmission.

[0023] Combined with Figure 2 、 Figure 3 and Figure 4 As shown, a battery compartment 10 is provided on the base 1, and a storage battery 11 is provided within the battery compartment 10. Combined with Figure 1 and Figure 4 As shown, a power indicator light 12 is provided at the bottom of the base 1. Combined with Figure 2 and Figure 3As shown, a power switch 13 is provided at the bottom of the base 1. In combination with Figure 1 and Figure 2As shown, anti-slip patterns are provided on both sides of the upper cover 2. Specifically, the battery compartment 10 is usually located at the bottom or side of the base 1. This design not only makes it convenient for users to open the cover with simple operations but also avoids accidental touch or damage during daily use. Inside the battery compartment 10, a mounting position suitable for the storage battery 11 is specifically provided. The types of storage batteries 11 include lithium batteries, nickel-metal hydride batteries, etc. They have advantages such as high energy density, long cycle life, and no memory effect, which can ensure the mouse works stably for a long time in the wireless state. The power indicator 12 usually uses an LED as the light source and indicates different power states through different colors or blinking modes. For example, when the power is sufficient, the indicator may show a stable green color; as the power decreases, the color may gradually change to yellow or red and may start to blink to remind the user to charge or replace the battery in time. This intuitive visual feedback method allows users to always know the power status of the mouse, so as to reasonably arrange the usage time and avoid the embarrassment of insufficient power at critical moments. The position of the power indicator 12 is arranged at a prominent position at the bottom of the base 1 to ensure that users can easily see it when using the mouse. At the same time, to maintain the overall aesthetics of the base 1, the indicator is usually cleverly integrated into the design of the base and does not appear obtrusive or affect the feel. In addition, the power indicator 12 may also have an intelligent energy-saving function. When the mouse is in the sleep state or not used for a long time, the indicator may automatically turn off or reduce the brightness to reduce unnecessary power consumption and extend the usage time of the mouse. This design not only reflects the care for the user experience but also demonstrates the fineness and thoughtfulness of the product design. The power switch 13, as a key component for controlling the power on and off of the mouse, is arranged at the bottom of the base 1 so that users can easily turn off the power when not using the mouse, thereby saving electric energy and extending the service life of the storage battery 11. The power switch 13 usually adopts forms such as a micro switch or a slide switch, which has the characteristics of simple operation and rapid response. Users can simply press or slide it to turn on or off the power. Some high-end mice may also be equipped with an intelligent power management function. When the mouse is not used for a long time, it can automatically enter the sleep state to reduce power consumption, and the power switch 13 becomes a convenient way for users to manually wake up the mouse or completely turn off the power. In addition, the design of the power switch 13 also fully considers durability and reliability. It is usually made of high-quality materials and has passed strict tests and verifications to ensure stable performance and reliable quality during long-term use. At the same time, to prevent external factors such as dust and moisture from damaging the power switch, some mice may also set waterproof and dustproof protection measures around it. To improve the stability and comfort of holding, anti-slip patterns are cleverly provided on both sides of the upper cover 2. These anti-slip patterns usually adopt a fine and uniform concave-convex design, which are closely arranged on the edges of both sides of the upper cover 2, providing good adhesion for the user's fingers.When the user holds the mouse and performs operations such as clicking, dragging, or swiping, the anti-slip patterns can effectively prevent the fingers from sliding on the mouse surface, thus ensuring the accuracy and stability of the operations. In addition to the anti-slip function, the anti-slip patterns also have a certain aesthetic quality. They are presented in the form of delicate and intricate lines or patterns, which are coordinated with the overall design style of the mouse, adding a unique charm to the product. At the same time, these patterns can also increase the friction on the mouse surface to a certain extent, preventing the mouse from sliding on a smooth desktop or accidentally falling.

[0024] Combined with Figure 1 、 Figure 2 and Figure 3 As shown, the fixed encoder 8, the circuit board 3, the storage battery 11, and the power switch 13 are electrically connected. Specifically, the fixed encoder 8, as an important component for detecting the rotation angle and speed of the roller 7, the signals output by it need to be processed and converted through the circuits on the circuit board 3, and finally converted into data that the computer can recognize. Therefore, a stable electrical connection must be established between the fixed encoder 8 and the circuit board 3 to ensure the accurate transmission and processing of signals. The circuit board 3 undertakes the interconnection and signal processing tasks of various electronic components. The circuit board 3 is not only connected to the fixed encoder 8, but also responsible for distributing the electrical energy provided by the storage battery 11 to each component that needs power supply, such as the microcontroller (MCU), etc. At the same time, the circuit board 3 is also connected to the power switch 13 through a certain circuit design to realize the user's control of turning on and off the mouse power supply. The storage battery 11, as the core of the mouse power supply, its electrical energy is distributed and regulated through the power management circuit on the circuit board 3 to meet the power supply requirements of each component. When the power switch 13 is in the on state, the storage battery 11 provides stable electrical energy to the circuit board 3 and the components on it; when the power switch 13 is turned off, the power supply is cut off, and the mouse enters the sleep or off state. The power switch 13 is connected to the storage battery 11 through the circuit on the circuit board 3, thereby realizing the control of turning on and off the power supply. When the user presses the power switch 13, the corresponding circuit on the circuit board 3 will detect this signal and control the storage battery 11 to supply power to each component or cut off the power supply.
