[0001] Related applications

[0002] This application claims priority to Chinese patent application 202423196184.1, filed on December 24, 2024, entitled "An Adjustable Mouse Base Plate and Mouse with Multiple PCB Mounting Positions". Technical Field

[0003] This application relates to the field of computer peripherals and human-computer interaction devices, and more specifically, to an adjustable mouse base plate and mouse with multiple PCB mounting positions. Background Technology

[0004] In current mouse designs, the mouse sensor is typically mounted on a PCB circuit board, which is then secured to the mouse base with screws to enable normal mouse functionality. This traditional design has been widely used in various mouse devices, but its limitations are becoming increasingly apparent, particularly in meeting users' personalized needs and improving the user experience.

[0005] Currently, the position of mouse sensors on the market is fixed and cannot be adjusted according to user operating habits. Specifically, the following shortcomings are particularly prominent:

[0006] 1. Limitations in User Experience: Due to varying operating habits among users, especially differences in their perception of mouse speed and sensitivity, fixed sensor designs cannot adapt to individual needs. This lack of adjustability makes it difficult for users to obtain an ideal tactile experience in daily use, leading to a decrease in user comfort.

[0007] 2. Limited Mouse Speed ​​Perception: Mouse speed (DPI) is commonly used to measure mouse sensitivity. However, in actual use, the perceived speed of the mouse depends not only on DPI but also on the distance between the user's wrist or elbow and the sensor when using it as a fulcrum. A fixed sensor position cannot meet the user's needs for different ranges of movement and fine adjustments, affecting operational accuracy and flexibility.

[0008] 3. Insufficient Adjustment Flexibility: Because the PCB board is fixed to the base plate with screws, the sensor position cannot be adjusted. This design limits the possibility for users to personalize the mouse sensitivity according to different operational needs, especially in scenarios that require both precise and fast operation.

[0009] In summary, these issues limit the performance of mouse devices in adapting to different user habits and improving the user experience. Therefore, a technical solution is needed that allows for flexible adjustment of the mouse sensor position to better meet user needs and improve operational efficiency and user comfort. Summary of the Invention

[0010] This application addresses the shortcomings of existing technologies by providing an adjustable mouse base plate and mouse with multiple PCB mounting positions. This solves the problems of traditional mice having fixed and inflexible sensor positions that cannot be adjusted according to user habits, thereby improving the control precision and smoothness of the mouse and meeting the needs of users in different usage scenarios.

[0011] To achieve the above technical objectives, this application will adopt the following technical solution:

[0013] Base plate main body;

[0014] PCB board mounted on the base plate body;

[0015] Sensors mounted on the PCB board;

[0016] The base plate body is provided with multiple PCB board mounting positions, which are used to selectively install the PCB board in any one of the PCB board mounting positions according to the user's operation requirements;

[0017] Each of the PCB board mounting positions has an optical sensor window at its bottom that matches the position of the sensor, allowing light from the sensor to pass through and receiving reflected light.

[0018] In a preferred embodiment, the PCB board mounting position is further connected to the PCB board via a snap-fit ​​or positioning hole.

[0019] In a preferred embodiment, the PCB board mounting position is further connected to the PCB board through positioning holes, wherein the positioning holes of the PCB board mounting position are internal threaded holes, and the PCB board is provided with through holes that correspond one-to-one with the positioning holes of the PCB board mounting position.

[0020] In a preferred implementation, each PCB mounting position is further distributed discretely on the base plate body.

[0021] In a preferred implementation, the PCB board is further connected to the main control circuit of the mouse via a flexible cable.

[0028] The beneficial effects of this application are:

[0029] First, the adjustable mouse base plate of this application, by setting multiple PCB board mounting positions, can flexibly adjust the mounting position of the PCB board according to the user's operating needs, thereby adapting to different mouse usage scenarios and improving the product's applicability and user experience. Simultaneously, each PCB board mounting position is equipped with an optical sensor window that matches the sensor position, ensuring that the sensor's light can accurately penetrate and receive reflected light signals, thus guaranteeing the accuracy and sensitivity of mouse positioning and improving the overall performance of the device.

[0030] Secondly, in the preferred implementation, this application uses a snap-fit ​​or positioning hole connection between the PCB mounting position and the PCB board, particularly the positioning hole connection, which effectively improves the stability and reliability of the installation.

For example, they can refer to a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, or a connection that allows communication between components. They can also refer to a direct connection or an indirect connection through an intermediate medium.

For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0041] Example 1

[0042] As shown in Figure 1 of the specification, this application describes an adjustable mouse base plate with multiple PCB mounting positions, including a base plate body 1, a PCB board 2 disposed on the base plate body 1, and a sensor 3 disposed on the PCB board 2. The base plate body 1 has multiple PCB mounting positions, allowing the user to selectively mount a PCB board at any of these positions according to their operational needs. By adjusting the PCB board mounting position, the sensor position can be changed, optimizing the user's haptic experience regarding mouse speed and sensitivity. Each PCB mounting position has an optical sensor window at its bottom that matches the position of the sensor 3. This not only allows the sensor 3 to emit light (or laser) through the optical sensor window and capture reflected light to determine the mouse's movement trajectory, but also reduces the overall weight of the mouse to meet lightweight design requirements. Especially in gaming mice, a lightweight design helps improve control flexibility and speed, while also aiding in heat dissipation to prevent internal components from overheating during prolonged use, thus ensuring the mouse's stable performance.

[0043] Specifically, the base plate 1 is made of high-strength, lightweight materials, such as carbon fiber composites or polymers, to ensure the stability and durability of the mouse structure during frequent adjustments. Multiple predefined PCB mounting positions are provided on the base plate 1, covering the entire working area of ​​the base plate 1 and providing maximum selection range for the sensor 3 position.

[0044] Each PCB mounting position is individually designed and distributed discretely across different areas of the base plate 1. Specifically, these mounting positions are independent of each other through precise spacing design, with optimized spacing to maximize the space utilization of the base plate 1 while accommodating different usage habits of mainstream users. The layout of the PCB mounting positions can be flexibly designed according to mouse usage requirements, for example, distributed along the longitudinal, transverse, or diagonal directions of the base plate 1, or arranged irregularly according to the sensor's capture angle and coverage requirements. Furthermore, the positioning of each PCB mounting position is coordinated with the overall structure of the base plate 1, ensuring that regardless of where the PCB 2 is installed, the sensor 3 can achieve efficient light emission and reflection capture through the optical sensor window, thereby ensuring the mouse's performance stability and the adjustability of the user experience.

[0045] In this implementation, the PCB board mounting position is connected to the PCB board 2 via a snap-fit ​​or positioning hole to ensure stable and convenient installation. The PCB board 2 can be freely switched between multiple PCB board mounting positions, and the installation position can be adjusted according to user needs. Taking the state shown in Figure 1 as an example, two sets of parallel PCB board mounting positions are provided on the base plate body 1. Each set of PCB board mounting positions is a positioning hole with screw holes. The PCB board mounting positions adopt 4-point positioning, and the PCB board 2 is provided with 4 through holes corresponding one-to-one with the positioning holes of the PCB board mounting positions. The user can remove the PCB board 2 from the current PCB board mounting position on the base plate body 1 and replace it with a PCB board mounting position that meets the operational requirements.

[0046] It should be noted that Figure 1 shows two PCB boards 2, one of which is in the installation state with the position changed. In actual use, there is only one PCB board 2.

[0047] PCB 2 is connected to the mouse main control circuit using a flexible cable (FPC). The flexible cable supports multiple bends and movements to meet the needs of frequent adjustments to PCB 2.

[0048] PCB board 2 is used to carry the sensor module and other electronic components, and to process the optical or electrical signals from the sensor. Sensor 3 is used to capture the displacement motion of the mouse and convert it into a signal output.

[0049] In another implementation, in addition to a PCB board mounting position on the main body 1 of the base plate, a slide rail is also provided on the inner bottom surface of the main body 1. The trajectory of the slide rail covers various user operating habits and mouse usage scenarios. The slide rail is embedded with ball bearings or low-friction material, and the edge of the PCB board 2 has a groove that engages with the guide rail in the slide rail, allowing the user to smoothly move the PCB board 2 to the target position. Once in place, it is fixed by the PCB board mounting position on the main body 1. The slide rail has both horizontal and vertical trajectory paths. The horizontal slide rail trajectory is arranged horizontally along the mouse base plate (X-axis direction), supporting the translation of the PCB board 2 in the left-right direction. The vertical slide rail trajectory is arranged vertically along the mouse base plate (Y-axis direction), supporting the movement of the sensor in the front-back direction.

[0050] In the implementation of this application, the slide rail covers 80% of the effective area of ​​the base plate body 1, supporting a longitudinal sliding range of 30mm and a lateral sliding range of 25mm for the PCB board.

[0051] The perceived speed of a mouse is determined not only by the DPI (Dots Per Inch) parameter of sensor 3, but also by the distance between sensor 3 and the user's pivot point (wrist or elbow). The position of the sensor changes the path length for the sensor to capture displacement, thus affecting the perceived speed. When PCB 2 is mounted near the rear of the mouse base, the distance between sensor 3 and the user's pivot point decreases, shortening the mouse's movement range and resulting in a slower perceived speed, but significantly improved accuracy. This is suitable for tasks requiring high precision and small adjustments, such as detailed drawing, 3D modeling, or text layout. When PCB 2 is mounted in the middle of the mouse base, sensor 3 is located at the natural center of the mouse, achieving a balance between perceived speed and accuracy. This is suitable for multitasking scenarios, such as office work, spreadsheet operations, or general daily use. When PCB board 2 is installed at the positioning point at the front of the mouse base, the distance between sensor 3 and the user's operating pivot point increases, amplifying the range of mouse movement and making the mouse feel faster. This is suitable for scenarios that require fast movement and response, such as FPS games, fast web browsing, or large-scale image editing.

[0052] Using the structure of this embodiment, the position of the PCB board 2 can be adjusted by changing the mounting positions of multiple PCB boards on the base plate 1, thereby adjusting the mouse sensitivity and meeting the personalized operation needs of users in different scenarios. Furthermore, with the detachable PCB board 2 of this embodiment, users can select different types of PCB boards (e.g., different sensor models, additional function keys, etc.) to personalize the mouse and meet diverse needs.

[0053] Example 2

[0054] As shown in Figures 2-3 of the specification, based on Embodiment 1, this application also provides a mouse, including an adjustable mouse base plate with multiple PCB mounting positions, a housing 4, a scroll wheel 5 disposed on the housing 4, and buttons.

[0055] The shell 4 is made of high-strength, lightweight materials such as ABS plastic, PC plastic, or aluminum alloy, providing excellent durability, impact resistance, and grip comfort. The top of the shell 4 features mounting holes for the buttons and scroll wheel 5. The sides of the shell 4 are ergonomically designed with grooves to optimize grip. The bottom of the shell 4 has several standardized screw holes for secure connection to the base plate 1, ensuring the stability of the overall mouse structure. The shell 4 is detachably connected to the mouse base plate, allowing users to replace the shell with different shapes or colors to meet their personalization needs.

[0056] In the preferred implementation, a rubber washer is embedded in the screw hole of the housing 4 to prevent loosening due to vibration during long-term use, and to reduce noise during installation.

[0057] The roller 5 is covered with anti-slip rubber or silicone to improve tactile feel and control precision. The roller 5 is fixed to the top of the housing 4 via a rotating shaft, with support mechanisms embedded at both ends of the shaft to ensure smooth rotation. Signal acquisition for the roller is accomplished by an optical sensor or mechanical encoder located next to the roller, which is connected to the PCB board below.

[0058] This application achieves flexible positioning, stable installation, and personalized customization of mouse components through an adjustable base plate design, diverse installation structures, and sensor fine-tuning functions, thereby improving adaptability, sensitivity, assembly efficiency, and user experience, while also enhancing functional expandability.
