Abstract
Description
Technical Field
[0001] The present application relates to the field of buttons, and in particular to a dual-mode switch button. Background Art
[0002] Existing switch button technology has been widely used in many applications, but there are still some shortcomings, especially in terms of accuracy, durability and response time. Traditional switch buttons rely on mechanical contacts or a single sensing method (such as magnetic or light sensing) to complete their functions, but these technologies may cause unstable signals and large operating errors under certain conditions, and may even be prone to wear or aging problems due to high frequency of use. In addition, a single sensing method is often difficult to cope with complex working environments or application scenarios that require high precision and high reliability. Therefore, how to improve the performance of switch buttons, especially in terms of accuracy, stability and service life, has become an important direction for current technological improvements.
[0003] In traditional technology, although magnetic induction switch buttons show good durability and reliability in some applications, their linearity and response accuracy are usually affected by many factors, such as external magnetic field interference, temperature changes or button aging. These factors may cause instability in magnetic induction data, making the triggering of switch buttons inaccurate, affecting the user experience. At the same time, buttons that rely solely on magnetic induction triggering may cause false triggering or delayed triggering in some complex usage scenarios, especially in devices that require high-precision operations, affecting their work efficiency and user experience. Summary of the invention
[0004] The purpose of this application is to overcome at least one of the shortcomings of the prior art and to provide a dual-mode switch button that corrects the magnetic induction data through a light-sensing signal, thereby significantly improving the linearity of the magnetic induction and ensuring that the switch button can work stably and accurately in a variety of environments. Light sensing is also used as a trigger reference, making the triggering process of the switch button more accurate and avoiding the problems caused by the single application of magnetic sensing. In addition, the combination of light sensing and magnetic sensing not only improves the reliability and accuracy of the system, but also extends the service life of the switch button, providing a more durable and reliable user experience.
[0005] To achieve the above-mentioned purpose, the present application discloses a dual-mode switch button, which includes a shell, a shaft body inserted into the shell, and a reset spring located in the shell for resetting the shaft body, wherein a light emitting end and a magnetic induction end are provided on the inner bottom surface of the shell; a card position is provided on the side of the shaft body, and correspondingly, a card platform is provided in the shell as a lower stop position of the shaft body stroke, and the card position cooperates with the card platform; a rod body extends downward from the shaft body, and the rod body is spaced and cooperates with the inner bottom surface of the shell when the shaft body is in the lower stop position; a magnetic block opposite to the magnetic induction end is embedded at the bottom end of the rod body of the shell; a reflecting inclined plane opposite to the light emitting end and at a 45-degree angle to the horizontal plane is provided at the bottom of the rod body, and oppositely, a light receiving end is provided in the shell that is horizontally opposite to the reflecting inclined plane when the shaft body is in the lower stop position, and when it is in the lower stop position, the reflecting inclined plane refracts the light emitted from the light emitting end into the light receiving end.
[0006] In some embodiments, a light shielding sheet is disposed on or above the upper surface of the light receiving end.
[0007] In some embodiments, the magnetic sensing end is a Hall sensor.
[0008] In some embodiments, the light emitting end is a light emitting diode, and the light receiving end is a photoelectric crystal.
[0009] In some embodiments, a reflective coating is disposed on the reflective inclined surface.
[0010] Compared with the prior art, the present invention has at least one of the following beneficial effects: 1. Improve accuracy and stability: The magnetic induction data is corrected by optical signals, which significantly improves the linearity of magnetic induction, ensuring that the switch buttons can work stably and accurately in different environments, avoiding the problem of unstable accuracy that may be caused by a single magnetic induction method.
[0011] 2. Enhanced durability: The combination of light and magnetic induction effectively extends the service life of the switch button. This design improves the anti-interference ability of the button and reduces the risk of wear and aging, so that the product can still maintain good performance under high-frequency use.
[0012] 3. Improve trigger accuracy: Using light as the trigger reference makes the trigger process of the switch button more accurate, avoiding false triggering or delayed triggering, and improving user experience and device response speed.

[0019] Refer to the attached Figure 1 This embodiment discloses a dual-mode switch button, whose structure and working principle provide a high-precision and high-stability switch button solution by combining the dual sensing methods of light sensing and magnetic sensing. The main components of the button include a housing 1, a shaft 2, a rod 201, a return spring 3, a light emitting end 4, a light receiving end 5, a magnetic sensing end 6, a magnetic block 7, a reflective slope 8, and other components matched therewith. Each component is precisely designed and matched to form a complete and efficient switch system, which can maintain excellent operating performance in various application scenarios.
[0020] First, the shell 1 serves as the outer frame of the entire switch button and provides structural support. The inner bottom surface of the shell 1 is provided with a light emitting terminal 4 and a magnetic sensing terminal 6. The position and design of these two components are crucial to the performance of this embodiment. The light emitting terminal 4 is a light emitting diode (LED) for emitting light of a specific wavelength; and the magnetic sensing terminal 6 is a Hall sensor for sensing changes in the magnetic field. The relative positions of the light emitting terminal 4 and the magnetic sensing terminal 6 are precisely arranged to ensure that the light and magnetic field signals can complement each other and work together to achieve high-precision triggering.
[0021] The shaft body 2 is one of the core components in this embodiment, responsible for executing key operations and transmitting input signals. A latch 7 is provided on the side of the shaft body 2, which is used to cooperate with the latch 5 in the shell 1 to form the lower stop of the stroke of the shaft body 2. During key operation, the latch 7 cooperates with the latch 5 to ensure that the shaft body 2 is pressed to a predetermined position, thereby accurately controlling the key stroke to avoid excessive pressing or inaccurate stroke. The rod 201 extending from the bottom of the shaft body 2 forms a gap with the inner bottom surface of the shell 1, thereby avoiding wear and inaccurate operation caused by mechanical contact.
[0022] The bottom end of the rod body 201 is embedded with a magnetic block 7 opposite to the magnetic sensing end 6. When the key is pressed, the magnetic block 7 in the rod body 201 will approach the Hall sensor 6, thereby triggering the change of the magnetic induction signal. In addition, a reflective inclined plane 8 is provided at the bottom of the rod body 201, which is opposite to the light emitting end 4 and is at a 45-degree angle to the horizontal plane. The function of the reflective inclined plane 8 is to refract the light emitted by the light emitting end 4 to the light receiving end 5, which is a photoelectric crystal. After receiving the reflected light, the photoelectric crystal will generate a signal feedback, thereby further activating the triggering process of the key.
[0023] During the key operation, when the shaft 2 moves to the lower stop position, the light emitted by the light emitting end 4 will be refracted by the reflective slope 8 and guided to the light receiving end 5. At the same time, the magnetic block 7 approaches the Hall sensor 6 to activate the magnetic field change. This dual triggering mechanism of light and magnetic induction can effectively improve the triggering accuracy and stability of the switch key, avoid the error caused by a single sensing method, and improve the reliability of the system.
[0024] In order to improve the stability and reliability of light sensing, in this embodiment, a light shield is provided on the upper surface or above the light receiving end 5 to prevent interference from external light sources. The light shield effectively blocks stray light and ensures that only light refracted by the reflective bevel 8 can enter the light receiving end 5, thereby ensuring the accuracy of the light sensing signal. In addition, in some embodiments, the reflective bevel 8 is coated with a reflective coating to improve the efficiency of light refraction and ensure that the light can be more effectively guided to the light receiving end 5, thereby improving the sensitivity and response speed of the system.
[0025] Through the above design, the dual-mode switch button of this embodiment can provide higher triggering accuracy and reliability. Compared with the traditional single induction switch, the dual-mode design of this embodiment effectively reduces the impact of external interference, environmental changes or magnetic induction signal fluctuations, thereby ensuring the stability of the button in various complex working environments. In equipment with high-frequency operation or high-precision requirements, especially in the fields of intelligent hardware, industrial automation equipment, precision instruments, etc., this embodiment can provide a more stable and durable solution.
[0026] In summary, the dual-mode switch button of this embodiment ensures high precision, high stability and long life of the button by combining light sensing and magnetic sensing. In practical applications, this technology not only reduces false triggering, but also improves the response speed and work efficiency of the device, providing users with a more stable and comfortable operating experience.
