Description

Technical Field

[0001] This utility model relates to the field of mechanical push button switch technology, specifically a silent mechanical push button switch with silicone reset feel. Background Technology

[0002] With the widespread adoption of computers, gaming devices, and smart terminals, mechanical keyboards have become increasingly popular due to their durability, clear tactile feedback, and high input efficiency. As a core component of the keyboard, mechanical key switches directly determine the typing feel, response speed, and noise level. In recent years, as the demands for "low noise and high response" in office and gaming environments have continued to rise, silent mechanical key switches have emerged on the market to meet the need for reduced noise interference in quiet office environments, late-night use, or public places.

[0003] Existing silent mechanical push-button switches are mainly achieved through structural optimization, buffer materials, or special reset components, but the problem of balancing tactile feel, noise control, and response speed still exists.

[0004] Currently, the most common keyboard switch structures fall into the following two categories: Spring-reset mechanical switches: This type of structure relies on a metal spring as the reset element. When the button is pressed and rebounds, the spring vibrates and rubs, which can easily produce obvious noise. At the same time, after long-term use, the spring may become fatigued, causing the feel to become unstable.

[0005] Silicone conductive keyboard switches: This type of structure relies on a single silicone cap or sheet to achieve key reset and conductivity. Although the noise is relatively low, the silicone is molded as a whole, making individual key replacement impossible and difficult to repair and personalize. In addition, the conductive response of silicone is relatively slow. Compared with mechanical switches with metal contact springs, its trigger response is sluggish, making it unsuitable for high-speed input or e-sports scenarios.

[0006] Therefore, existing technologies either fall short in terms of noise reduction or have significant shortcomings in response speed and maintainability. Thus, it is clear that existing technological solutions urgently need to improve the structure of silent mechanical push-button switches to address their technical deficiencies. Utility Model Content

[0007] The purpose of this invention is to provide a silent mechanical push-button switch with silicone reset feel to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a silent mechanical key switch with silicone reset feel, comprising a silicone shell, a lower cover, a switch assembly and reset silicone disposed between the silicone shell and the lower cover, the switch assembly comprising a shaft, a conductive block and a connector, the connector being connected to the keyboard circuit; The lower end of the spindle is inserted into one end of the conductive block. When the spindle is pressed down, the other end of the conductive block contacts the connector and makes the connector connected to the keyboard circuit. The reset silicone is inserted between the shaft core and the lower cover. When the shaft core is reset, the connector and the button electrofusion connection are disconnected.

[0009] Compared with the prior art, the beneficial effects of the above-mentioned technical solution of this utility model are: This application utilizes reset silicone as the reset element. Compared to traditional metal spring reset structures, this invention's silent mechanical push-button switch effectively reduces vibration and friction during button rebound, significantly lowering noise levels and providing users with a quieter operating environment. Simultaneously, the use of reset silicone provides a soft and stable tactile feel, enhancing the user experience.

As a further improvement of the silent mechanical key switch with silicone reset feel of this application, the connector includes a first spring and a second spring. The first spring has a first connecting end and the second spring has a second connecting end. When the conductive block connects the first connecting end and the second connecting end, the connector is connected to the keyboard circuit.

The receiving groove is provided with an opening for the lower end of the conductor block away from the shaft core to pass through.

[0013] As a further improvement of the silent mechanical push button switch with silicone reset feel of this application, the reset silicone is a bowl-shaped silicone body with a stepped part and a through groove for the conductive block to pass through. The lower end of the shaft core is provided with a locking protrusion, which has a locking hole for one end of the conductor block to be inserted into. The cam is engaged in the stepped part.

[0014] As a further improvement to the silent mechanical push-button switch with silicone reset feel of this application, a reset buffer structure is provided on both sides of the shaft core along the width direction, and the reset buffer structure contacts the stepped part.

[0015] As a further improvement of the silent mechanical push button switch with silicone reset feel of this application, the reset silicone has a hollow structure with a curved surface that curves upward from the center outward.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all implementation methods.

[0021] In this application, the existing technical solutions that rely solely on springs for mechanical switches, while offering sensitive responses, suffer from noise limitations due to their high structural rigidity. Conversely, the opposing technical solutions rely solely on silicone's reset and conductive structures, which, while providing quiet operation, fail to meet high-performance requirements in terms of conductivity and response speed. Therefore, the inventors of this application were motivated to improve the technology by introducing a mechanical metal spring and conductive block structure, while retaining the advantages of silicone's quiet operation and reset capabilities, to achieve rapid conductive response.

[0022] Furthermore, considering the product's versatility, the inventors hoped that the improved structure would be compatible with conventional mechanical keyboard switches, enabling replacement and universal installation. Thus, the technical solution of this application was developed.

[0023] Based on the following embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Implementation

[0025] likeFigures 1-3 As shown, in order to solve the technical defects in the existing technical solutions, this application provides a silent mechanical key switch with silicone reset feel, including a housing 1, a lower cover 2, a switch assembly 3 and a reset silicone 4 disposed between the housing 1 and the lower cover 2. The switch assembly 3 includes a shaft core 31, a conductive block 32 and a connector 33, and the connector 33 is connected to the keyboard circuit. The lower end of the shaft core 31 is inserted into one end of the conductive block 32. When the shaft core 31 is pressed down, the other end of the conductive block 32 contacts the connector 33 and makes the connector 33 conductive to the keyboard circuit. The reset silicone 4 is for the conductive block 32 to pass through and is disposed between the shaft core 31 and the lower cover 2 to reset the shaft core 31. When the shaft core 31 is reset, the connector 33 is disconnected from the keyboard circuit.

[0026] Specifically, in practical application, when the user presses the pivot 31, the lower end of the pivot 31 pushes the conductive block 32 to move. The other end of the conductive block 32 then contacts and presses the first connecting end 3311 and the second connecting end 3321 of the first spring 331 and the second spring 332, causing the first spring 331 and the second spring 332 to deform. The connector 33 of this application includes a first spring 331 and a second spring 332. The first spring 331 has a first connecting end 3311, and the second spring 332 has a second connecting end 3321. When the conductive block 32 connects the first connecting end 3311 and the second connecting end 3321, the connector 33 is connected to the keyboard circuit.

[0027] Furthermore, the first spring contact 331 is provided with a first transition portion 3312 fixedly connected to the first connecting end 3311, and a first extension portion 3313 is vertically arranged on the side of the first transition portion 3312 away from the first connecting end 3311; the second spring contact 332 is provided with a second transition portion 3322 fixedly connected to the second connecting end 3321, and a second extension portion 3323 is vertically arranged on the side of the second transition portion 3322 away from the second connecting end 3321; the first extension portion 3313 and the second extension portion 3323 are connected to the keyboard circuit. The first extension portion 3313 and the second extension portion 3323 are electrically connected through the conductive block 32, thereby enabling the connector 33 to conduct to the keyboard circuit and trigger a key signal. When the user releases the key switch 31, the key switch 31 returns to its original position under the elastic action of the reset silicone 4. The conductive block 32 then disengages from the first connecting end 3311 and the second connecting end 3321. The first spring contact 331 and the second spring contact 332 return to their original positions. The electrical connection between the first extension portion 3313 and the second extension portion 3323 is broken, and the connection between the connector 33 and the keyboard circuit is also broken, completing one key press action. During this process, the reset silicone 4 not only performs a reset function but also effectively reduces vibration and friction due to its soft material, thus lowering the noise level.

[0028] Specifically, in the above-mentioned technical solution of this application, the reset silicone 4 serves both as a reset component for the shaft core 31 and absorbs impact and reduces noise when the shaft core 31 is pressed to the bottom, thus achieving both reset stability and quiet operation. Furthermore, this application achieves rapid mechanical conductivity by setting a metal spring and a conductive block 32, which is more sensitive to conductivity and has less input delay compared to silicone, making it suitable for high-intensity input. Therefore, while reducing noise and improving the feel, it ensures triggering speed and service life, overcoming the shortcomings of existing spring switches and silicone switches.

[0029] Implementation

[0030] like Figures 1-4 As shown, unlike Embodiment 1, this application aims to further improve the connection structure between the connector 33 and the keyboard circuit. The lower cover 2 of this application has a first through hole 21 and a second through hole 22. The first through hole 21 allows the first extension portion 3313 to pass through and connect to the keyboard circuit; the second through hole 22 allows the second extension portion 3323 to pass through and connect to the keyboard circuit. Through this design, the first extension portion 3313 and the second extension portion 3323 can be securely connected to the keyboard circuit, ensuring stable signal transmission. Simultaneously, the arrangement of the first through hole 21 and the second through hole 22 facilitates assembly and maintenance, improving product reliability and service life.

[0031] Furthermore, the lower cover 2 is provided with a receiving groove 23, in which the first spring 331 and the second spring 332 are both assembled. The receiving groove 23 is provided with an opening 231, through which the lower end of the conductive block 32 away from the shaft core 31 passes. Through the receiving groove 23, the first spring 331 and the second spring 332 are well fixed and supported, preventing loosening or damage due to vibration or friction during button presses. Simultaneously, the opening 231 of the receiving groove 23 allows the conductive block 32 to smoothly pass through and contact the first spring 331 and the second spring 332, ensuring accurate transmission of button signals. This structural design not only enhances the product's durability but also improves the user experience.

[0032] Furthermore, the reset silicone 4 is a bowl-shaped silicone body with a stepped portion 41 and a through groove 411 for the conductive block 32 to pass through. The stepped portion 41 design allows the reset silicone 4 to be more securely positioned on the lower cover 2 during installation, while the through groove 411 provides space for the conductive block 32 to pass through, further ensuring stable transmission of the button signal. The bowl-shaped design of the reset silicone 4 allows it to deform evenly under pressure, providing users with a smooth and stable reset feel. In addition, the edges of the bowl-shaped silicone body also serve as dustproof and waterproof, improving the product's durability and reliability. This reset silicone 4 design not only optimizes the button feel but also provides users with a more comfortable and stable button experience.

[0033] Specifically, the lower end of the shaft core 31 is provided with a locking protrusion 311, which has a locking hole 3111 for one end of the conductive block 32 to be inserted into. The locking protrusion 311 is engaged in the stepped portion 41. Thus, a stable engagement is achieved between the shaft core 31 and the reset silicone 4, ensuring the stability and accuracy of the button during pressing and resetting. The engagement of the locking hole 3111 of the locking protrusion 311 with the conductive block 32 not only enhances the connection strength between the shaft core 31 and the reset silicone 4, but also effectively prevents loosening or detachment that may occur during prolonged use. Simultaneously, the design of the locking protrusion 311 engaging in the stepped portion 41 allows the shaft core 31 to return to its initial position more smoothly during reset, providing the user with a smoother and more consistent button feedback.

[0034] Furthermore, reset buffer structures 312 are provided on both sides of the shaft core 31 along its width direction, and the reset buffer structures 312 contact the stepped portion 41. The design of the reset buffer structures 312 allows the reset silicone 4 to further absorb the impact force when the shaft core 31 resets during specific applications, reducing vibration and noise, while providing a softer touch. The reset buffer structures 312 can be made of soft materials, such as rubber or silicone, to ensure good shock absorption performance. When the shaft core 31 resets, the reset buffer structures 312 contact the stepped portion 41, absorbing the impact force through their deformation, thereby further reducing the noise level and improving the user experience. This design not only optimizes the silent effect but also enhances the stability and durability of the push-button switch, making it more suitable for scenarios involving long-term use and high-intensity input.

[0035] Other aspects that are the same as in Implementation Method 1 will not be described again in this application.

[0036] Implementation

[0037] like Figures 1-6As shown, unlike Embodiment 1, the reset silicone 4 in this application has a hollow structure with a curved shape extending outwards from the center. An edge flange 42 is provided along the bottom outer edge of the reset silicone 4, which is used to fix it to the housing 1. Therefore, the hollow structure of the reset silicone 4 not only reduces the overall weight but also allows it to deform more flexibly under pressure, further improving the reset feel and quietness of the button. The edge flange 42 ensures a stable connection between the reset silicone 4 and the housing 1, avoiding loosening or detachment during use, and improving the reliability and service life of the product.

[0038] Furthermore, the switch core 31 is provided with a housing 313 and a key head 314 assembled in the housing 313. The key head 314 is used to insert keyboard keycaps. The top of the key head 314 is designed with a cross-shaped three-dimensional rib for inserting keyboard keycaps; the housing 1 is provided with an assembly cavity 11 for receiving the key head 314. Furthermore, the housing 313 of the switch core 31 and the housing 1 can be fixed by snaps, threads or other suitable connection methods to ensure the stability and accuracy of the switch core 31 during keystrokes. The cross-shaped three-dimensional rib design of the key head 314 not only increases the contact area with the keyboard keycaps and improves the stability of the connection, but also makes it easier to align and insert the keyboard keycaps during installation, improving the convenience and efficiency of assembly. In addition, the cross-shaped three-dimensional rib structure can also increase the tactile feedback of the key to a certain extent, allowing users to feel a clearer and more distinct tactile sensation when pressing the key, thus improving the user experience.

[0039] Other aspects that are the same as in Implementation Method 1 will not be described again in this application.
