Description

Technical Field

[0001] The present application relates to the field of mouse technology, and more specifically, to a key structure that realizes functions through magnetic induction. Background Art

[0002] As society develops, more and more young people are pursuing personalization and customization. This leads to the demand for various master micro switches to be used in consumer electronic mice.

[0003] Mouse primary microswitches currently on the market generally utilize electrical induction to achieve their functions, primarily in the form of plug-in or surface-mount microswitches. These switches typically utilize soldering to force the contacts to engage and spring open. However, this contact-based operation results in a fixed press stroke, requiring the switch to be pressed to a specific position to activate. This fixed press stroke restricts user comfort and operating habits. Because different users have varying preferences for pressure and travel, a fixed press stroke cannot meet diverse needs, leading to discomfort or operational inconvenience for some users.

The micro-switch lower cover 2 is provided with a micro-switch button 3. The micro-switch button 3 is provided with a button magnet 4 for magnetic induction inside. A micro-switch spring 7 is provided on one side of the micro-switch lower cover 2. A through hole 6 is opened inside the micro-switch upper cover 1, and the top end of the micro-switch button 3 passes through the through hole 6.

[0033] A fixing groove 5 for installing a button magnet 4 is provided inside the micro-switch button 3 on one side of the micro-switch lower cover 2. The structure of the fixing groove 5 is adapted to the structure of the button magnet 4. The bottom of the micro-switch button 3 and the bottom of the button magnet 4 are on the same horizontal plane. The bottom of the micro-switch button 3 is snapped into the top of the micro-switch lower cover 2. The bottom of the micro-switch button 3 and the button magnet 4 are in contact with the top of the micro-switch spring 7.

[0034] When the user presses the mouse button, the up and down displacement of the micro button 3 and the button magnet 4 can realize flexible adjustment of the pressing stroke. Different users can set the most comfortable pressing depth according to their personal habits and needs, which increases the personalization and comfort of use. Based on magnetic induction, the magnetic field changes of the button magnet 4 and the PCBA Hall chip (PCBA Hall chip is an existing technology and will not be described here) can be detected more quickly and accurately, so that the mouse function responds faster and more accurately, reducing operation delays, and the button magnet 4 can provide unique magnetic feedback when the user presses it, so that the pressing action has a better sense of touch and rhythm, making the operation process more comfortable and enjoyable, and meeting the various special requirements of different consumers for mouse operation. Whether it is a gamer who pursues fast clicks or an office worker who needs long-term comfortable operation, they can find a setting that suits them.

[0035] Reference Figure 1-Figure 3 The micro-switch spring 7 is plugged into the top of the micro-switch lower cover 2. Fixing holes 10 are provided on both sides of the bottom of the micro-switch upper cover 1. Blocks 9 are provided on both sides of the micro-switch lower cover 2. Each block 9 is respectively engaged with the corresponding fixing hole 10. Pins 8 are provided at the bottom of the micro-switch lower cover 2, and the number of pins 8 is set to multiple.

[0036] By plugging in the micro-switch spring 7, snapping in the clamping block 9 and the fixing hole 10, and inserting the spring pin 8 into the PCB hole, the disassembly and installation of each component becomes simple and quick, and maintenance and replacement are convenient at any time.

[0037] Example 2

[0038] Reference Figure 5 The difference between this embodiment and the first embodiment is that an arc pad 11 is provided on one side of the button magnet 4, and a buffer pad 12 is provided on the side of the button magnet 4 away from the arc pad 11, and the button magnet 4 contacts the inner wall of the fixing groove 5 through the buffer pad 12.

[0039] The arc pad 11 and the buffer pad 12 can provide a certain elastic buffer when the user presses the mouse button, making the pressing process softer and further improving the comfort of operation. The buffer pad 12 can reduce the collision and friction between the button magnet 4 and the inner wall of the fixing groove 5 under frequent pressing, reduce the loss of components, and extend the overall service life of the mouse micro switch.

[0040] Example 3

[0041] Reference Figure 6 The difference between this embodiment and the first and second embodiments is that a circular groove 13 is provided on the side of the button magnet 4 away from the arc pad 11, an annular pad 14 is provided on the inner wall of the circular groove 13, and a universal ball 15 is fixedly connected to one side of the inner wall of the fixing groove 5, and the structure of the circular groove 13 is adapted to the structure of the universal ball 15.

[0042] The cooperation between the universal ball 15 and the circular groove 13 makes the movement of the button magnet 4 more flexible and free, and can adapt to pressing operations in more different directions and angles, thereby improving the diversity and convenience of user operations. This structure helps to more accurately control the position of the button magnet 4, making the sensing of magnetic field changes more accurate, thereby further improving the response accuracy and performance of the mouse. In addition, the rolling contact method of the universal ball 15 greatly reduces friction compared to simple sliding contact, reduces component wear, and extends service life.

[0043] Working principle: In the micro switch of the mouse, a magnet is assembled below the micro button 3. When the user presses the mouse button, the micro button 3 moves downward, driving the button magnet 4 below to move up and down. Due to the movement of the button magnet 4, the relative position between it and the PCBA Hall chip changes, resulting in a change in the magnetic field. The PCBA Hall chip can detect the change in this magnetic field and convert it into an electrical signal. By processing and interpreting these electrical signals, the corresponding function of the mouse is realized.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
