AI Technical Summary
The mechanical contacts of a conventional mouse are prone to wear as the number of presses and the pressing force increase, resulting in a reduction in lifespan. The aging of the elastic parts causes the buttons to sag and be accidentally pressed, and there is also a lot of noise.
A Hall effect micro switch is used, which triggers the switch through the adsorption and detachment mechanism of the permanent magnet and the metal sheet. The permanent magnet is used to adsorb the metal sheet to drive the power arm to reset the button, avoiding direct contact with the Hall effect IC, reducing wear and noise.
It improves the lifespan of the mouse, ensures consistent button pressure and reset speed, reduces noise, and avoids problems caused by mechanical contact wear and elastic component aging.

Description
Technical Field
[0001] The invention belongs to the technical field of mice, and in particular relates to a Hall effect micro switch and a mouse. Background Art
[0002] A mouse is an external computer input device and serves as an indicator for the vertical and horizontal coordinates of a computer display system. With the increasing popularity of video games and the rapid development of e-sports, computer users have come to expect a longer lifespan for their mouse buttons. Conventional mice primarily use mechanical contacts on a circuit board to trigger computer input commands. Consequently, the lifespan of the push-button switches gradually decreases with increasing frequency and force. Summary of the Invention
[0003] The object of the present invention is to provide a Hall effect micro switch and a mouse to solve the technical defects described in the background art.
[0004] The Hall effect micro switch comprises a micro element, an upper cover, a middle cover and a lower cover, the micro element is provided with a first force arm and a second force arm, one end of the first force arm is fixedly connected to the second force arm and forms an angle, a rotating shaft is provided at the connection between the first force arm and the second force arm, the other end of the first force arm is provided with a sliding shaft, the other end of the second force arm is fixed with a permanent magnet, the upper cover is provided with a button, the bottom of the button is provided with a pressing block, the pressing block is provided with a sliding groove, the sliding shaft slides in the sliding groove, the rotating shaft is connected to the middle cover bearing, and the middle cover is fixedly installed with a permanent magnet. The metal sheet on the top is adsorbed by the permanent magnet, and the lower cover is fixedly installed with a Hall IC located below the permanent magnet. The torque when the button is pressed is less than the torque applied by the permanent magnet, so that when the button is pressed to a certain position, the button pushes the first force arm down through the pressing block, and the first force arm drives the permanent magnet on the second force arm to separate from the adsorbed metal sheet and approach the Hall IC without contacting the Hall IC. When the button stops being pressed, the permanent magnet moves away from the Hall IC by adsorbing the metal sheet and drives the second force arm, the first force arm, the pressing block and the button to reset.
[0005] According to the technical solution, the present invention can achieve the following beneficial effects:
[0006] 1. As the button pushes the first lever arm downward through the pressing block, the first lever arm drives the permanent magnet on the second lever arm to separate from the adsorbed metal sheet and approach the Hall IC to trigger the switch. This solves the mechanical wear of the mechanical contacts of a conventional mouse caused by increasing the number of presses and the pressing force, thereby improving the service life of the mouse.
[0007] 2. When the button stops being pressed, the second lever arm drives the first lever arm to reset by attracting the metal sheet through the permanent magnet, and the first lever arm drives the pressing block to rise, and the pressing block drives the button to rise and reset. In contrast, in conventional mice, the lifting of the button is driven by the elastic member. Therefore, the present invention can solve the problems of the conventional mouse, such as the drooping of the button due to the wear and aging of the elastic member, which causes the mechanical contact to be accidentally touched and the key pressing stroke to be shortened. At the same time, the present invention can better ensure that the force required to press the button each time is relatively consistent.
[0008] 3. Compared with conventional mice that use elastic parts to drive the button to reset, the present invention uses the permanent magnet to attract the metal sheet to drive the button to reset when the button stops being pressed, thereby improving the reset speed;
[0009] 4. Since the torque when the button is pressed is smaller than the torque applied by the permanent magnet, the feel of the button is ensured each time it is pressed, and the button can be reset stably;
[0010] 5. Since the permanent magnet can trigger the switch without the need for a Hall IC, the present invention can reduce noise when a button is pressed to trigger a command.
[0011] In order to further optimize the above technical solution, it can be optionally combined with one or more of the following implementation methods without conflict.
[0012] In some embodiments, the middle cover is provided with a limit block located between the Hall IC and the permanent magnet, so that the permanent magnet is in close contact with the limit block when it approaches the Hall IC;
[0013] According to the technical solution, the present invention can further achieve the following beneficial effects:
[0014] 1. After the permanent magnet is separated from the metal sheet it is adsorbed on, it can prevent the permanent magnet from hitting the Hall IC and causing damage to the Hall IC;
[0015] 2. After pressing the button to drive the permanent magnet to separate from the adsorbed metal sheet, the permanent magnet can impact, thereby emitting a feedback sound of pressing the button. When the button stops being pressed, the permanent magnet adsorbing the metal sheet can produce an impact, thereby emitting a feedback sound of stopping pressing the button.
[0016] In some embodiments, a strength reinforcement rib is provided on the second lever arm; according to the technical solution, the second lever arm is prevented from breaking when the key is pressed with excessive force, thereby improving the life of the second lever arm.
[0017] In some embodiments, a first lever arm is provided on both sides of the second lever arm; according to the technical solution, when the key is pressed, the second lever arm can be driven to move more stably by the first lever arm, and the key can be supported more stably.
[0018] In some embodiments, the first lever arm is made of an elastically deformable material to achieve a force storage lever arm;
[0019] According to the technical solution, the present invention can further achieve the following beneficial effects:
[0020] 1. When the button is pressed, the button drives the first lever to bend, so that the first lever accumulates force against the downward pressure of the button. When the button is pressed to a certain position (that is, when the downward pressure of the button is greater than the suction force of the permanent magnet), the first lever releases the accumulated force, thereby pushing the permanent magnet on the second lever quickly close to the Hall IC, thereby increasing the switch triggering speed;
[0021] 2. When the button is not pressed down to a certain position, the first force arm accumulates the downward force of the button, and the permanent magnet continues to attract the metal sheet, thus preventing the permanent magnet from approaching the Hall IC and triggering an erroneous instruction.
[0022] The mouse described above has the Hall micro switch, and the lower cover is equipped with a mainboard circuit, the mainboard circuit is electrically connected to the Hall IC, and the mainboard circuit is electrically connected to a power supply device. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to make the objectives, technical solutions and advantages of the present invention more clear, this specific embodiment further describes the present invention in detail with reference to the accompanying drawings.
[0036] like Figures 1 to 7 As shown, this specific embodiment provides a Hall effect micro switch and a mouse.
[0037] The Hall effect micro switch comprises a micro element 4, an upper cover 1, a middle cover 2 and a lower cover 3. The micro element 4 is provided with a first force arm 41 and a second force arm 42. One end of the first force arm 41 and the second force arm 42 are fixedly connected and form an angle. A rotating shaft 43 is provided at the connection between the first force arm 41 and the second force arm 42. The other end of the first force arm 41 is provided with a sliding shaft 411. The other end of the second force arm 42 is fixed with a permanent magnet 421. The upper cover 1 is provided with a button 11. The bottom of the button 11 is provided with a lower pressing block 12. The lower pressing block 12 is provided with a sliding groove 13. The sliding shaft 411 slides in the sliding groove 13. The rotating shaft 43 is connected to the bearing of the middle cover 2. The middle cover 2 is fixedly installed with a metal sheet 2 located above the permanent magnet 421 and adsorbed by the permanent magnet 421. 1. The lower cover 3 is fixedly mounted with a Hall IC 31 located below the permanent magnet 421. The torque when the button 11 is pressed down is less than the torque applied by the permanent magnet 421, so that when the button 11 is pressed down to a certain position, the button 11 pushes the first lever 41 downward through the pressing block 12, and the first lever 41 drives the permanent magnet 421 on the second lever 42 to separate from the adsorbed metal sheet 21 and approach the Hall IC 31 without contacting the Hall IC 31. When the button 11 stops being pressed, the permanent magnet 421 moves away from the Hall IC 31 by adsorbing the metal sheet 21 and drives the second lever 42, the first lever 41, the pressing block 12 and the button 11 to reset.
[0038] Since the button 11 pushes the first force arm 41 downward through the pressing block 12, the first force arm 41 drives the permanent magnet 421 on the second force arm 42 to separate from the adsorbed metal sheet 21 and approach the Hall IC 31 to trigger the switch, so as to solve the problem of contact wear of the mechanical contacts of the conventional mouse due to the increase in the number of presses and the increase in the pressing force, thereby improving the service life of the button 11; in addition, since when the button 11 stops being pressed, the second force arm 42 adsorbs the metal sheet 21 through the permanent magnet 421 to drive the first force arm 41 to reset, the first force arm 41 drives the pressing block 12 to rise, and the pressing block 12 drives the button 11 to rise and reset, while the conventional mouse drives the button 11 to rise through the elastic member. Therefore, the present invention can solve the problem of the conventional mouse having the button 11 drooping due to the wear and aging of the elastic member. The mechanical contacts that are accidentally touched and the pressing stroke of the button 11 are shortened. At the same time, the present invention can better ensure that the force required to press the button 11 each time is relatively consistent. In addition, compared with the conventional mouse that drives the button 11 to reset through the elastic member, when the button 11 is stopped, the permanent magnet 421 absorbs the metal sheet 21 to drive the button 11 to reset, thereby improving the reset speed. In addition, since the torque when the button 11 is pressed down is less than the torque applied by the permanent magnet 421, the feel of each time the button 11 is pressed is ensured, and at the same time, when the button 11 is pressed down, the permanent magnet 421 can be stably driven to separate from the adsorbed metal sheet 21 and approach the Hall IC 31. In addition, since the permanent magnet 421 can trigger the switch without contacting the Hall IC 31, it is possible to reduce noise when pressing the button 11.
[0039] In some embodiments, the middle cover 2 is provided with a limit block 22 located between the Hall IC31 and the permanent magnet 421, so that the permanent magnet 421 is close to the limit block 22 after approaching the Hall IC31; after the permanent magnet 421 is separated from the adsorbed metal sheet 21, the permanent magnet 421 can be prevented from hitting the Hall IC31 and causing damage to the Hall IC31. In addition, after pressing the button 11 to drive the permanent magnet 421 to separate from the adsorbed metal sheet 21, the permanent magnet 421 can be able to impact, thereby emitting a feedback sound of pressing the button 11, and when the button 11 stops being pressed, the impact caused by the permanent magnet 421 adsorbing the metal sheet 21 can be emitted, thereby emitting a feedback sound of stopping pressing the button 11.
[0040] In some embodiments, a strength reinforcement rib 422 is provided on the second lever arm 42 to prevent the second lever arm 42 from breaking when the button 11 is pressed with excessive force, thereby increasing the life of the second lever arm 42 .
[0041] In some embodiments, first lever arms 41 are provided on both sides of the second lever arm 42 so that when the button 11 is pressed, the second lever arm 42 can be driven to move more stably by the first lever arm 41 and the button 11 can be supported more stably.
[0042] In some embodiments, the first lever arm 41 is made of elastically deformable material to realize a force storage lever arm.
[0043] When the button 11 is pressed, the button 11 drives the first force arm 41 to bend, so that the first force arm 41 accumulates the downward force of the button 11. When the button 11 is pressed down to a certain position (that is, when the downward force of the button 11 is greater than the suction force of the permanent magnet 421), the first force arm 41 will release the stored force, thereby pushing the permanent magnet 421 on the second force arm 42 to quickly approach the Hall IC31, thereby increasing the switch triggering speed; when the button 11 is not pressed down to a certain position, the first force arm 41 accumulates the downward force of the button 11, and the permanent magnet 421 will continue to attract the metal sheet 21, thereby preventing the permanent magnet 421 from approaching the Hall IC31 and triggering an erroneous instruction.
