Description

Technical Field

[0001] The utility model relates to the technical field of mice, in particular to a novel waterproof mouse. Background Art

[0002] Among many electronic devices, the mouse is one of the main devices for human-computer interaction, and its importance is self-evident. However, traditional mouse designs often cannot prevent the entry of moisture or dust, which may affect the life and performance of the mouse. Once moisture or dust enters the inside of the mouse, it may cause problems such as circuit short circuit and component corrosion, thus affecting the normal operation of the mouse. In addition, the mouse's wheel recognition system usually relies on a mechanical encoder or a magnetic encoder, but the mechanical encoder is not waterproof. Although the magnetic control encoder can solve the problem of waterproofing, the feel of use is greatly reduced, and the accuracy may be insufficient. It cannot meet some application scenarios with high precision requirements, especially in some strong magnetic environments (such as medical scenarios or special industrial use scenarios).

[0003] There are some shortcomings in the existing technology:

[0004] 1. Insufficient waterproof performance: The design of traditional mice usually does not take waterproofing into consideration. Once moisture enters the mouse, it may cause circuit short circuits, component corrosion and other problems, thus affecting the normal operation of the mouse.

[0005] 2. Not dustproof and corrosion-resistant: In addition to the waterproof problem, the design of traditional mice does not take dustproof and corrosion-resistant issues into consideration, which may reduce the service life of the mouse.

[0006] 3. Insufficient encoder accuracy: The scroll wheel recognition system of a traditional mouse usually relies on a mechanical encoder or a magnetic encoder, but the accuracy of these encoders may be insufficient to meet some application scenarios with high accuracy requirements.

[0007] 4. Unable to be used in specific scenarios: Due to the above problems, traditional mice may not be used in some special application scenarios, such as medical scenarios and industrial environments with strong magnetic fields.

[0008] 5. The installation and fixing methods of the mouse are limited: The structural design of the traditional mouse is usually relatively fixed and cannot be flexibly adjusted and optimized according to different application requirements.

[0009] Therefore, the prior art has deficiencies and needs further improvement. Utility Model Content

[0010] Aiming at the problems existing in the prior art, the utility model provides a novel waterproof mouse.

[0011] To achieve the above purpose, the specific scheme of the utility model is as follows:

[0012] The utility model provides a novel waterproof mouse, comprising:

[0014] An optical tracking sensor chip is arranged inside the roller rim, inside the roller axle, or outside the roller shaft;

[0015] The optical tracking sensor chip is used to detect the rotation of the roller through photoelectric elements;

[0016] The optical tracking sensor chip uses two photoelectric elements offset by a set angle to detect the rotation of the roller. By detecting the signal difference between the two elements, the direction and speed of the roller's rotation are determined.

[0017] The roller is mounted on a bracket, and the bracket is mounted on the PCB board.

[0018] Furthermore, a mechanical encoder is provided on the other side of the roller to improve the feel of the roller rotation.

[0019] A water filter port is provided at the bottom of the bracket for filtering water to prevent water from entering and affecting the sensitivity of the roller; a shell is also provided on the outside of the PCB board, and a sealing layer is provided between the PCB board and the shell.

[0020] Furthermore, a photoelectric motion sensing component is also provided on the PCB board of the mouse;

[0021] The motion sensing component includes an LED light and an optical sensor. The LED light is used to emit light to the surface, and then the optical sensor detects the reflected light to detect the movement of the mouse on the surface;

[0023] Furthermore, a protective sealing cover is provided on the PCB board at the LED lamp and the optical sensor.

[0026] The technical solution of the utility model has the following beneficial effects:

[0028] High precision: The application of optical tracking sensor can accurately determine the rotation direction and speed of the scroll wheel, thereby improving the accuracy of mouse use.

[0029] Suitable for special scenarios: Due to its waterproof, dustproof and corrosion-resistant properties, the mouse can be used in some special application scenarios, such as medical and industrial scenarios with strong magnetism and requiring waterproof function.

[0047] Combination Figure 1-Figure 5As shown, the utility model provides a new waterproof mouse, including: a scroll wheel 3, an optical tracking sensor chip 4 is arranged on one side of the scroll wheel 3, the chip uses two photoelectric elements offset at a certain angle to detect the rotation of the scroll wheel 3, and the rotation direction and speed of the scroll wheel 3 can be determined by detecting the signal difference between the two elements; the scroll wheel 3 is mounted on a bracket 2, and the bracket 2 is mounted on a PCB board 1. The optical tracking sensor chip 4 can also be arranged inside the rim of the scroll wheel 3, inside the axle of the scroll wheel 3, or outside the rotating shaft of the scroll wheel 3; the optical tracking sensor chip 4 can be installed in any position as long as the rotation of the scroll wheel 3 can be detected by the photoelectric element. A conventional mechanical encoder can also be arranged on the other side of the scroll wheel 3 to improve the feel of the rotation of the scroll wheel 3.

[0048] The bottom of the bracket 2 is provided with a water filter port 201 for filtering water to prevent water from entering and affecting the sensitivity of the roller 3 ; the outer side of the PCB board 1 is also provided with a shell 5 , and waterproof silica gel is provided between the PCB board 1 and the shell 5 .

[0049] A motion sensing component is also provided on the PCB board 1 of the mouse; the motion sensing component includes an LED lamp 101 and an optical sensor 102, the LED lamp 101 is used to emit light to the surface, and then the optical sensor 102 detects the reflected light, thereby detecting the movement of the mouse on the surface; a waterproof silicone seal is provided at the bottom of the mouse to achieve waterproofness of the bottom of the mouse.

[0050] The PCB board 1 is also provided with a cover plate 103 at the LED lamp 101 and the optical sensor 102. The optical sensor 102 includes a chip (but not limited to) FCT3065-XY. The PCB board 1 is also provided with a wireless module for wireless version signal transmission.

[0051] The principle of this utility model is as follows:

[0052] Movement and positioning of the mouse: When the user moves the mouse on a surface, the LED light 101 at the bottom of the mouse emits light to the surface, and the reflected light is then detected by the optical sensor 102, thereby detecting the movement of the mouse on the surface. The optical sensor 102 contains the chip FCT3065-XY, which is a high-precision optical sensor 102 that can accurately detect the movement of the mouse.

[0053] Detection of the scroll wheel 3: The scroll wheel 3 of the mouse is mounted on the bracket 2. When the user scrolls the scroll wheel 3, the optical tracking sensor chip 4 detects the rotation of the scroll wheel 3. The optical tracking sensor chip 4 has two photoelectric elements that are offset at a certain angle. By detecting the signal difference between the two elements, the rotation direction and speed of the scroll wheel 3 can be determined.

[0054] Waterproof function: The waterproof function of the mouse is mainly achieved through three parts. First, a waterproof sealing layer is set between the PCB board 1 and the shell 5 and at the bottom of the mouse to prevent moisture from entering the mouse. Secondly, a water filter 201 is set at the bottom of the bracket 2 to drain the moisture that enters the mouse. Finally, a protective sealing cover 103 is set at the LED light 101 and the optical sensor 102 on the PCB board 1 to prevent moisture from directly contacting these sensitive optical components.

[0055] Wireless connection: The mouse is wirelessly connected to the computer through a wireless module provided on the PCB board 1, thereby realizing wireless operation.

[0056] Through the above design, high-precision operation can be achieved, and at the same time it has good waterproof performance, which is suitable for use in various environments, especially in special environments that require waterproofing, dustproofing, corrosion resistance or strong magnetic fields, such as medical and industrial scenes.

[0057] A mechanical encoder usually consists of a small metal or plastic wheel with some small holes in it. When the roller 3 turns, the wheel will also turn, and a light source (usually a small LED light) will emit light from one side, and a photoresistor or photodiode on the other side. The light will hit the photosensitive element through the small holes, and the brightness of the light will change due to the rotation of the wheel. This change can be detected by the circuit and converted into an electrical signal, which is then sent to the computer, so that the computer can know the rotation of the roller 3.

[0058] The optical tracking sensor chip 4 uses two photoelectric elements offset at a certain angle to detect the rotation of the roller 3. By detecting the signal difference between the two elements, the rotation direction and speed of the roller 3 can be determined.

[0059] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the protection scope of the utility model.
