Description

Technical Field

[0001] This utility model relates to the field of keyboards, specifically to an inductive keyboard switch. Background Technology

[0002] A keyboard is an input device used to input text, numbers, symbols, and commands into a computer or other electronic device. It typically consists of multiple keys, each representing a letter, number, or other function. The main types of keyboards include mechanical keyboards, membrane keyboards, and wireless keyboards, and the keyboard switch is an important component that triggers the keys on the keyboard.

[0003] Currently, keyboard switches are divided into mechanical switches, magnetic induction switches, and inductive keyboard switches. The principle of inductive switches is mainly to sense the proximity of objects to trigger the key. When a metal object approaches the inductor coil, the current in the inductor coil will change, which will cause a change in the internal circuit level, thereby triggering the key. Inductive keyboard switches have a very fast triggering speed, which can reach millisecond-level response, greatly improving the user experience.

[0004] However, in the current technology, the sound triggered by the inductive keyboard switch is relatively small, so it lacks the fun of the mechanical trigger sound when the keyboard is turned on, and the keyboard switch structure is not stable enough and is prone to loosening. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an inductive keyboard switch to solve the technical problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an inductive keyboard switch, including a base and a top cover movably connected. Multiple sets of positioning posts are fixed to the bottom of the top cover. A limiting hole matching the positioning posts is opened at the top of the base. A spring is installed inside the base, and a push shaft is movably installed inside the base. A shaft core is fixed to the bottom of the push shaft, and a metal part is fixed to the bottom of the shaft core. A boss is fixed to the bottom end of the inner wall of the base. A slider is fixed to one side of the push shaft, and a protrusion is fixed to the outer wall of the push shaft.

[0007] By adopting the above technical solution, the keyboard switch structure is made more robust and reduces shaking by connecting the positioning post and the limiting hole. The slider on the key shaft slides in contact with the protrusion on the inner wall of the slide groove, reducing the contact area with the slide groove and making the key shaft slide more smoothly. When the key shaft is pressed, it hits the protrusion on the base, making the keyboard switch emit a mechanical sound effect to enhance the enjoyment of the keyboard typing sound.

[0008] The present invention is further provided that the base has a sliding groove inside, and the inner wall of the sliding groove has a protrusion fixed thereon.

[0009] Preferably, the groove facilitates the sliding of the slider inside and limits the movement direction of the button shaft. At the same time, the protrusion reduces the friction between the slider and the groove, thus making the sliding of the button shaft smoother.

[0010] The present invention is further configured such that the top of the upper cover is provided with a shaft hole, and the inner wall of the shaft hole is provided with a clearance hole.

[0011] Preferably, the shaft hole allows for easy restriction of the movement direction of the push shaft, and the clearance hole reduces the contact area between the push shaft and the top cover, thereby reducing the friction between the push shaft and the top cover.

[0012] The present invention is further configured such that an installation groove is provided on the outer wall of the upper cover, and a light guide is installed on the inner wall of the installation groove.

[0013] Preferably, the mounting slot facilitates the installation of the light guide sword, and the light guide is connected to the top cover by a buckle. The light guide allows light to pass through easily, making it look cooler.

[0014] The present invention is further configured such that a connecting sleeve is fixed inside the base, and multiple sets of fixing blocks are fixed on the inner wall of the connecting sleeve.

[0015] Preferably, the connecting sleeve can limit the movement of the shaft.

[0016] The present invention is further configured such that the end of the metal part is tapered.

[0017] Preferably, the tapered metal part can better enter the interior of the connecting sleeve, avoiding jerking when pressing the shaft.

[0018] In summary, the present invention has the following main advantages:

[0019] This invention features a positioning post, a slider, a boss, and a key shaft. The positioning post connects to the limiting hole, making the keyboard switch structure more secure and reducing wobbling. The slider on the key shaft slides in contact with the protrusion on the inner wall of the slide groove, reducing the contact area with the slide groove and making the key shaft slide more smoothly. When the key shaft is pressed, it impacts the boss on the base, causing the keyboard switch to produce a mechanical sound effect, thus enhancing the enjoyment of typing. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] Please see Figures 1-5 The keyboard includes a base 1, which is movably connected to a top cover 2. The bottom of the top cover 2 is fixed with multiple sets of positioning pins 23. The top of the base 1 is provided with limiting holes 11 that match the positioning pins 23. The positioning pins 231 cooperate with the limiting holes 11 to make the keyboard switch structure more secure and reduce shaking. A spring 6 is installed inside the base 1, and a key shaft 3 is movably installed inside the base 1. A shaft core 31 is fixed at the bottom of the key shaft 3, and a metal part 32 is fixed at the bottom of the shaft core 31. A boss 7 is fixed at the bottom of the inner wall of the base 1, and a slider 34 is fixed on one side of the key shaft 3. When the key shaft 3 is pressed, the key shaft 3 will compress the spring when it is pressed down. The bottom of the key shaft 3 will make a sound when it contacts the boss 7. At the same time, the protrusion 33 on the outer wall of the key shaft 3 contacts the protrusion 13, which can reduce the friction when the key shaft 3 slides down. The protrusion 33 is fixed on the outer wall of the key shaft 3.

[0030] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The base 1 has a groove 12 inside, and a protrusion 13 is fixed on the inner wall of the groove 12. The groove 12 allows the slider 34 to slide inside, limiting the movement direction of the push shaft 3. At the same time, the protrusion 13 can reduce the friction between the slider 34 and the groove 12, making the push shaft 3 slide more smoothly.

[0031] For details regarding the above embodiments, please refer to [link / reference]. Figure 2The top of the upper cover 2 is provided with a shaft hole 5, and the inner wall of the shaft hole 5 is provided with a clearance hole 22. The shaft hole 5 can conveniently limit the movement direction of the push shaft 3. The clearance hole 22 can reduce the contact area between the push shaft 3 and the upper cover 2, thereby reducing the friction between the push shaft 3 and the upper cover 2.

[0032] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 2 The outer wall of the top cover 2 is provided with an installation groove 21, and the inner wall of the installation groove 21 is provided with a light guide 4. The installation groove 21 can facilitate the installation of the light guide sword 4. The light guide 4 is connected to the top cover 2 by a buckle. The light guide 4 can facilitate the passage of light, thus making it more dazzling.

[0033] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 3 The base 1 has a connecting sleeve 8 fixed inside, and the inner wall of the connecting sleeve 8 is fixed with multiple sets of fixing blocks 81. The connecting sleeve 8 can limit the movement of the shaft core 31.

[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The end of the metal part 32 is tapered, which allows the metal part 32 to enter the interior of the connecting sleeve 8 more easily, avoiding any jerking when pressing the shaft 3.

[0035] In practical operation, when the present invention is used, the pressing shaft 3 is pressed down. When the pressing shaft 3 is pressed down, the spring is squeezed. The bottom of the pressing shaft 3 contacts the boss 7 and makes a sound. At the same time, the protrusion 33 on the outer wall of the pressing shaft 3 contacts the protrusion 13, which can reduce the friction when the pressing shaft 3 slides down. When the pressing shaft 3 is released, the spring 6 drives the pressing shaft 3 to return to its original position.
