Description

Technical Field

[0001] The present application relates to the field of switch buttons, in particular to a switch button. Background Art

[0002] Existing mechanical switch buttons are widely used in various devices. Their main feature is to generate switch actions through physical contact and provide intuitive and reliable feedback. Mechanical switch buttons usually have a distinct operating feel, allowing users to perceive obvious feedback when pressing, and this feedback can be expressed in the form of touch or sound. Many users prefer a crisp button feel because this feel can provide clear operating instructions during use, ensuring that users can confirm whether the button is successfully triggered. However, this design may generate unnecessary noise interference in some usage scenarios.

[0003] With the increasing demand for noise control in office environments and public places, some users are beginning to face new challenges when using mechanical switches. When pursuing a crisp feel, mechanical switches are usually accompanied by loud sound feedback, especially when the key pressure is high. This kind of noise is easy to cause interference in a quiet office environment, especially in places such as offices, affecting the work or rest of people around. Although some high-end mechanical switch designs provide softer feedback sounds, these designs often find it difficult to balance the contradiction between the crispness of the feel and noise control. Therefore, how to reduce noise without sacrificing the operating feel has become a major challenge in mechanical switch design.

[0004] Existing technologies have not yet been able to effectively solve this problem. Existing mechanical switch button designs mostly focus on improving the operating feel or sound control, but rarely consider how to meet the dual needs of crisp feel and noise suppression without adding extra complexity. Although some products on the market currently use rubber rings or special materials for noise reduction, these designs often affect the touch of the buttons, cannot achieve an ideal balance, or are too costly and are not suitable for large-scale applications.

[0005] Therefore, it is particularly important to develop a new type of switch button that can provide a crisp feel while effectively controlling noise. Summary of the invention

[0006] The purpose of this application is to overcome at least one of the deficiencies of the prior art and provide a switch button that can not only improve the user experience and provide a higher quality of operation perception, but also better adapt to different usage environments, especially offices and public places that are sensitive to noise, and improve the operation experience by reducing the impact on the surrounding environment.

[0007] To achieve the above-mentioned purpose, the present application discloses a switch button, which includes a shell, a shaft body inserted into the shell, a reset spring installed in the shell and used for resetting the shaft body, and a trigger assembly installed in the shell and cooperating with the shaft body to realize trigger output, wherein the shaft body has a handle and a rod portion extending downward from the bottom surface of the handle; a guide structure for linearly guiding the shaft body is provided in the shell, and at the same time, a ring platform is provided on the inner bottom surface of the shell for opposing the rod portion in the shaft body, and the bottom of the ring platform cooperates with the lower end of the rod portion in the shaft body; the lower end of the rod portion in the shaft body is a spherical structure, and the rod portion is a hollow structure, and a plurality of shock-absorbing blocks are arranged in the hollow cavity of the hollow structure of the rod portion; a shock-absorbing rubber layer is attached to the outer bottom surface of the shell and the outer wall surface outside the ring.

[0008] In some embodiments, the bottom of the ring platform is an arc-shaped protrusion that contacts and cooperates with the tail end of the shaft body.

[0009] In some embodiments, the trigger assembly includes a magnetic block installed in the shaft body and a Hall element installed in the housing and opposite to the magnetic block.

[0010] In some embodiments, the trigger assembly is a spring switch, and accordingly, a push block that cooperates with the spring switch is convexly provided on the shaft.

[0011] In some embodiments, the rod portion in the shaft rod is a hollow plastic rod, and the shock-absorbing blocks are freely stacked, and the stacking height is 0.3-0.7 times the hollow height of the rod portion.

[0012] Compared with the prior art, the present invention has at least one of the following beneficial effects: 1. Improve the operating feel and reduce noise: By setting a hollow structure and shock-absorbing block in the shaft body, the impact force during key operation can be effectively absorbed, the sound feedback of the keys can be reduced, and thus noise interference can be reduced. It is especially suitable for offices and public places that require a low-noise environment, while maintaining a crisp key feel.

[0013] 2. Enhance the stability and durability of the keys: The matching design of the spherical rod and the ring of the shaft ensures the stability of the keys, avoids deviation or irregular movement during key operation, and thus improves the service life and reliability of the switch keys.

[0014] 3. Efficient vibration absorption performance: The design of the hollow structure and shock-absorbing blocks effectively improves the comfort of the keys under high-frequency operation, reduces vibration during operation, and further improves the user's operating experience, especially for users who use it for a long time.

[0015] 4. Design flexibility to adapt to different trigger requirements: By adopting the design of different trigger components such as magnetic blocks, Hall elements, and spring switches, the present invention can provide a variety of trigger mechanisms to meet the requirements of key response characteristics in different devices or application scenarios, and has strong adaptability and customizability.

[0016] The above-listed beneficial effects are not exhaustive of all advantages. Other potential beneficial effects and detailed technical implementations will be further disclosed in the examples or other description parts of this application. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] See attached Figure 1-4 This embodiment provides a specific design of a switch button, which aims to achieve a balance between crisp feel and noise control by improving the structure and function of the button, and is particularly suitable for noise-sensitive environments such as offices and homes. The button not only improves the accuracy and comfort of the operating feel through the careful design and coordination of various structural components, but also effectively reduces the noise pollution during key operation, ensuring a quiet and stable use environment.

[0026] The switch button is mainly composed of several key components, including the housing 1, the shaft 2, the return spring, the trigger assembly, the shock absorption design, etc. The various components are coordinated with each other in structure, and a good operating experience and noise control effect are achieved through precise coordination. The following will describe in detail the design, material selection, working principle and coordination of these components.

[0027] The shell 1 serves as the external support structure of the switch button. Its main function is to protect the internal components and provide installation guidance and other functions. The internal design of the shell 1 has been carefully laid out, and a guide structure is provided inside to guide the linear motion of the shaft body 2 to ensure smooth and stable key operation. A ring platform 6 is provided on the bottom surface of the shell, which is precisely matched with the lower end of the rod 4 in the shaft body 2 to play a supporting and positioning role. The bottom of the ring platform 6 is designed as an arc-shaped protrusion, and contacts with the spherical structure 5 at the lower end of the shaft body rod 4. Through this structural coordination, the button can be well guided during the pressing process to avoid the button from getting stuck or not smooth due to uneven pressure.

[0028] The shaft body 2 is the core component of the switch button, carrying the input signal of the user's operation. The shaft body 2 is composed of a handle 3 and a rod 4. The handle 3 is the part that the user directly touches, and pressure is applied by pressing the handle; the rod 4 extends downward from the bottom of the handle 3 and moves linearly through the guide structure of the shell 1. The lower end of the rod 4 is designed as a spherical structure 5. This design can not only reduce friction and noise during the pressing process, but also maintain smoothness and comfort during operation. The spherical structure 5 cooperates with the arc-shaped protrusion at the bottom of the ring 6 to ensure stability and smoothness when the button is pressed.

[0029] The rod 4 of the shaft body 2 adopts a hollow structure 7. This design can not only reduce the overall weight, but also provide space for the installation of the shock-absorbing block 8. A number of shock-absorbing blocks 8 are arranged in the hollow structure 7 in the rod 4. These shock-absorbing blocks are made of elastic materials (such as rubber or silicone) and can effectively absorb vibrations when keys are pressed, reducing the vibrations transmitted to the user's fingers and the surrounding environment. The number and stacking height of the shock-absorbing blocks 8 are precisely calculated, and the stacking height is 30% to 70% of the hollow height of the rod 4. This design ensures that the shock-absorbing blocks 8 can effectively absorb the impact force when the key is pressed and avoid the rebound phenomenon of the key.

[0030] The additional weight of the shock-absorbing block 8 can help the key achieve a fixed shape. When the key is impacted by external force, the shock-absorbing block 8 can absorb the impact energy through its elastic deformation, and move downward as the key is pressed, thereby preventing the key from rebounding, ensuring the stability and crisp feedback feel during the pressing process. In addition, due to the presence of the shock-absorbing block 8, the vibration generated during the key operation can be effectively absorbed, preventing the noise from being transmitted through the key body during the key pressing process, thereby making the key quieter, which is particularly suitable for application scenarios that require low noise.

[0031] A shock-absorbing rubber layer 9 is attached to the outer bottom surface of the housing 1 and the outer wall of the ring platform 6, which further enhances the shock absorption and noise control capabilities of the keys. The shock-absorbing rubber layer 9 is generally made of high-density silicone or polyurethane materials, which have strong vibration absorption performance and can effectively reduce the propagation of vibration during key operation, prevent the vibration from being transmitted to the surrounding environment through the housing 1, and achieve the effect of noise suppression.

[0032] In terms of the design of the trigger component, this embodiment provides two different triggering methods, namely a magnetic trigger component and a shrapnel switch component. The magnetic trigger component includes a magnetic block installed in the shaft body 2, and a Hall element opposite to the magnetic block in the housing 1. When the button is pressed, the shaft body 2 moves, the magnetic block approaches the Hall element, the Hall element senses the change in the magnetic field and triggers the signal output. This design has high response accuracy and can respond to user operations in a short time. Another trigger component is a shrapnel switch component, and a push block is provided on the shaft body 2. The push block cooperates with the shrapnel switch. When the button is pressed, the push block pushes the shrapnel to realize signal triggering. The shrapnel switch has a simple structure and a fast response speed, and is suitable for scenarios that require high-frequency pressing.

[0033] The switch button of this embodiment improves the hand feel through the above design, while ensuring the stability and crispness during operation, and is particularly suitable for use in noise-sensitive environments. The design of the shock-absorbing block 8 not only helps the button reduce the impact of vibration on the user's hand, but also effectively suppresses the noise pollution caused by the button operation, thereby improving the comfort and durability of the button. The design of the trigger component also provides two options according to different usage requirements, which can meet the needs of different devices and scenarios.

[0034] The switch button design of this embodiment can reduce the noise generated by the button without sacrificing the operating feel, and is particularly suitable for offices, homes and other places that require quiet and low noise. The combination of shock-absorbing design and high-precision trigger system not only improves the button usage experience, but also has a significant effect in reducing environmental noise, and has broad application prospects.

[0035] Through the technical solution of this embodiment, a switch button with optimized structure, enhanced functions and excellent noise control is provided, which solves the problems of excessive noise and unclear feel in the prior art. It has extremely high practicality and promotion value, especially in modern office environments, and can greatly improve the user experience of buttons and reduce the noise impact on the surrounding environment.

[0036] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims.
