Description

Technical Field

[0001] This utility model relates to the field of keyboard accessories technology, specifically to a detachable reinforced keyboard switch. Background Technology

[0002] In the field of computer input devices, the keyboard, as an important human-computer interaction tool, is crucial in terms of performance and user experience. The keyboard switches, as a core component, directly affect key indicators such as typing feel, response speed, and durability. When keyboard switches malfunction or require replacement, due to unreasonable structural design, disassembly and repair are often difficult. Users may need to replace the entire keyboard or incur high costs for professional repairs. Existing switches often have unsatisfactory bottom-out cushioning, producing significant noise, and prolonged typing can cause finger fatigue. Utility Model Content

[0003] The purpose of this invention is to provide a detachable reinforced keyboard switch to solve the problem of inconvenient disassembly of existing keyboard switches mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A detachable reinforced keyboard switch includes a detachable reinforced top cover and a base. The top of the reinforced top cover is equipped with a spindle, and the bottom surface of the base is provided with a bottom-contact cushioning pad.

[0006] The reinforced top cover is symmetrically provided with connecting buckles on both sides, and the base is symmetrically provided with snap-fit ​​connectors on both sides that are adapted to the size of the connecting buckles and engage with them.

[0007] Both the reinforced top cover and the base include a base body, the surface of which is provided with an anti-collision shell, and the inner wall of which is provided with a nylon bottom shell. The surfaces of the anti-collision shell and the nylon bottom shell are provided with a protective coating.

[0008] Preferably, the protective coating is a waterproof or dustproof coating with a thickness of 20-50 μm, enabling the keyboard switches to effectively resist the intrusion of external moisture and dust. The waterproof coating prevents water vapor penetration, avoiding short circuits and other malfunctions caused by moisture in the internal circuitry; the dustproof coating reduces dust adhesion to the switch surface, preventing dust from entering the interior and affecting the normal operation of components. An appropriate thickness ensures the protective performance of the coating without increasing costs or affecting other switch performance due to excessive thickness, thereby extending the lifespan of the keyboard switches and improving their reliability.

[0009] Preferably, the base is equipped with a stationary contact plate, a moving contact plate, and a positioning post, which ensures the stability and consistency of the internal structure of the keyboard switch and helps to improve the overall performance of the keyboard.

[0010] Preferably, the inner wall of the base is symmetrically provided with reinforcing columns on both sides for the vertical movement of the spindle. This enhances the structural strength of the base and allows it to better withstand the forces generated when the spindle moves up and down. Simultaneously, it provides a stable support frame for the spindle's movement, making the spindle more stable during operation, reducing noise and wear caused by spindle wobbling, and improving the feel and stability of keyboard typing.

[0011] Preferably, the inner wall of the reinforcing column is provided with a guide groove, and the two sides of the spindle are provided with guide sliders that are adapted to the cross-sectional size of the guide groove and slide in cooperation. The cooperation between the guide groove and the guide slider can strictly limit the movement trajectory of the spindle, prevent the spindle from deviating or tilting during the up and down movement, ensure the accuracy and smoothness of the spindle movement, and further optimize the keyboard operation experience.

[0012] Preferably, the top center of the spindle is equipped with a keycap connecting post with a cross-shaped cross section for installing keycaps. The cross-shaped structure provides a good fixing effect, preventing the keycaps from loosening or falling off during use, while also allowing users to easily replace keycaps according to their personal needs, thus satisfying users' pursuit of keyboard personalization.

[0013] Preferably, the bottom-contact cushioning pad is made of silicone with a thickness of 0.5-1mm. Silicone material has good elasticity and cushioning performance. When the keyboard switch bottoms out, it can effectively absorb and disperse the impact force, reduce the noise generated by typing, reduce the impact on the user's fingers, alleviate finger fatigue caused by prolonged typing, and improve the user's keyboard comfort.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In this detachable reinforced keyboard switch, a detachable reinforced top cover and base are provided. The connecting buckles on both sides of the reinforced top cover are engaged with the snap-fit ​​connectors on both sides of the base, enabling convenient assembly and disassembly of the top cover and base. The main shaft at the top of the reinforced top cover ensures the basic function of the keyboard switch, and the bottom-contact buffer pad on the bottom surface of the base provides a cushioning effect when the keyboard switch touches the bottom. The anti-collision shell on the surface of the base enhances the impact resistance, and the nylon bottom shell on the inner wall of the base provides stable internal support. Furthermore, the protective coating on the surface of the anti-collision shell and the nylon bottom shell further enhances the overall protective performance. This structure is reasonably designed and highly practical. Attached Figure Description

[0025] Detachable reinforced keyboard switches, such as Figures 1-3As shown, the device includes a detachable reinforced top cover 10 and a base 20. A main shaft 30 is mounted on the top of the reinforced top cover 10, and a bottom-contact buffer pad 40 is provided on the bottom surface of the base 20. Connecting buckles 12 are symmetrically arranged on both sides of the reinforced top cover 10, and snap-fit ​​connectors 24, which are adapted to the size of the connecting buckles 12 and engage with them, are symmetrically arranged on both sides of the base 20. Both the reinforced top cover 10 and the base 20 include a base 13. An anti-collision shell 14 is provided on the surface of the base 13, and a nylon bottom shell 15 is provided on the inner wall of the base 13. A protective coating 11 is provided on the surfaces of the anti-collision shell 14 and the nylon bottom shell 15. The design incorporates a detachable reinforced top cover 10 and a base 20. The top cover is secured by connecting clips 12 on both sides of the reinforced top cover, which engage with the base by clips 24 on both sides of the base, allowing for easy assembly and disassembly of the top cover and base. The main spindle 30 on the top of the reinforced top cover ensures the basic function of the keyboard switches, while the bottom-contact cushioning pad 40 on the bottom of the base provides cushioning when the keyboard switches touch the bottom. The impact-resistant shell 14 on the surface of the base 13 enhances impact resistance, and the nylon bottom shell 15 on the inner wall of the base provides stable internal support. Furthermore, the protective coating 11 on the surfaces of the impact-resistant shell and the nylon bottom shell further improves the overall protective performance. This structural design is reasonable and highly practical.

[0026] Furthermore, the protective coating 11 is a waterproof or dustproof coating with a thickness of 20-50μm, which enables the substrate 13, the shock-absorbing shell 14, and the nylon bottom shell 15 to better resist the erosion of water and dust, thereby improving the protective performance and service life of the keyboard switches.

[0027] The base 20 is equipped with a stationary contact 21, a moving contact 22, and a positioning post 23, which enables the keyboard switches to control the on / off state of the circuit. The positioning post 23 helps to accurately position and install each component, ensuring the normal operation of the keyboard switches.

[0028] Specifically, the inner walls of the base 20 are symmetrically provided with reinforcing columns 25 for the spindle 30 to move up and down. The inner sidewalls of the reinforcing columns 25 are provided with guide grooves 26. The spindle 30 is provided with guide sliders on both sides that are adapted to the cross-sectional dimensions of the guide grooves 26 and slide together, so that the spindle 30 is more stable and smooth during the up and down movement, reducing shaking and deviation, and improving the accuracy of keyboard operation.

[0029] In addition, a keycap connecting post 31 with a cross-shaped cross section is installed at the top center of the spindle 30 for installing keycaps, which allows the keycaps to be installed conveniently and securely on the spindle 30, making it easy for users to replace keycaps as needed.

[0030] It is worth noting that the bottoming-out buffer pad 40 is made of silicone with a thickness of 0.5-1mm, which effectively cushions the keyboard switches when they bottom out, reduces typing noise, and improves the typing feel for the user.

[0031] The working principle of this detachable reinforced keyboard switch:

[0032] First, if keycaps need to be installed, align the keycaps with the keycap connecting post 31 at the center of the top of the spindle 30, and press firmly to securely install the keycaps on the spindle 30. This is existing technology and will not be elaborated here. During the operation of the keyboard switch, when the keycaps are pressed, the guide sliders on both sides of the spindle 30 move downwards along the guide grooves 26 on the inner sidewalls of the reinforcing posts 25 on both sides of the inner wall of the base 20, ensuring that the spindle 30 is pressed down stably. At this time, the moving contact 22 on the base 20 contacts the stationary contact 21, realizing circuit conduction and transmitting the signal.

[0033] When the keycap is pressed down to the bottom, the bottom-contact cushioning pad 40 on the bottom surface of the base 20, which is made of 0.5-1mm thick silicone cushioning pad, plays a role in cushioning the impact of the downward press and reducing noise.

[0034] When the keycap is released, the spindle 30 springs upward under the action of the internal structure, and the guide slider moves steadily upward along the guide groove 26. If the keyboard switch needs to be maintained or parts replaced, the reinforcing top cover 10 and the base 20 can be easily disassembled and separated because there are connecting buckles 12 on both sides of the reinforcing top cover 10 and matching snap-fit ​​connectors 24 on both sides of the base 20. This makes it convenient to inspect and replace internal components such as the spindle 30, stationary contact 21, and moving contact 22.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
