Description

Technical Field

[0001] This utility model relates to the field of push-button switch technology, and in particular to a magnetic shaft with high light transmittance and high stability. Background Technology

[0002] A keyboard is a device used to input instructions and data to operate equipment. It also refers to a set of function keys arranged by a system to operate a machine or device. The keyboard is the most commonly used and primary input device, allowing users to input English letters, numbers, punctuation marks, etc., into a computer, thereby issuing commands and inputting data.

[0003] Current magnetic switch keyboards typically have an LED near each key to illuminate the characters on the keycaps or to provide lighting effects for the keys. This LED is usually mounted on one side of the key switch, but due to obstruction by the keycaps and other components, the LED's illumination range is limited, usually only illuminating about half of the key. Overall, the lighting effect is uneven and inconsistent. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this invention is to provide a high-transmittance and high-stability magnetic axis. Without affecting the conduction of the key switches, the structure of the dual light guide pillars and / or transparent top cover allows the light on the circuit board to diffuse across the entire axis, significantly improving the uniformity and coordination of the light, ensuring the keyboard's lighting effect, and enhancing the user experience. Furthermore, the limiting mechanism of the guide core and base allows the Hall element on the circuit board to better sense the magnetic axis, thereby improving the sensing accuracy of this magnetic axis.

[0005] The technical solution adopted by this utility model to achieve the above objectives is as follows:

[0006] A high-transmittance and high-stability magnetic shaft includes a base, a top cover disposed on the base, a guide core movably disposed between the base and the top cover, a return spring disposed between the guide core and the base, and a magnet disposed in the lower end of the guide core. It also includes limiting posts symmetrically disposed on the lower end surface of the guide core and protruding downwards. The inner wall of the base is symmetrically formed with limiting bosses that are integrally upwardly protruding and directly opposite the limiting posts. A limiting groove is formed in the middle of the limiting bosses, which is recessed downwards for the limiting posts to be inserted.

[0007] As a further improvement of this utility model, a limiting guide rail is formed on the inner wall of the base, which is located outside the limiting boss and is in the shape of an I-beam. A limiting slider that slides on the limiting guide rail is formed on the outer wall of the guide core.

[0008] As a further improvement of this utility model, light-giving grooves for light to pass through are symmetrically formed on the base.

[0009] As a further improvement of this utility model, a light guide column, which is in the shape of a "∟" and embedded in the light clearance groove, is provided between the top cover and the base. The lower end of the light guide column is embedded in the light clearance groove, and the upper end of the light guide column is fastened to the side wall of the base.

[0010] As a further improvement of this utility model, a light-relief portion is formed on the upper cover, which communicates with the light-relief groove.

[0011] As a further improvement of this utility model, a light guide fixing block is formed on each side of the light guide post, which protrudes outward and whose lower end face is fastened to the upper end face of the side wall of the base. Light guide fixing grooves for embedding the light guide fixing blocks are formed on both sides of the lower end face of the side wall of the upper cover.

[0012] As a further improvement of this utility model, the outer wall of the catheter column is provided with outwardly protruding arc-shaped protrusions on both sides.

[0013] As a further improvement of this utility model, the upper end of the light guide post is a semi-circular arc or a sloping structure that extends obliquely from the lower outside to the upper inside.

[0014] As a further improvement of this utility model, the top cover is a transparent top cover or a semi-transparent top cover.

[0015] As a further improvement of this utility model, the upper cover has a light refraction part that is recessed inward and has a right-angle shape at the position of the light clearance groove.

[0016] The beneficial effects of this utility model are as follows:

[0017] The magnetic shaft is configured to include a base, an upper cover disposed on the base, a guide core movably disposed between the base and the upper cover, a return spring disposed between the guide core and the base, and a magnet disposed in the lower end of the guide core. It also includes limiting posts symmetrically disposed on the lower end surface of the guide core and protruding downwards. The inner wall of the base is symmetrically formed with limiting bosses that are integrally upwardly protruding and directly opposite the limiting posts. A limiting groove is formed in the middle of the limiting bosses, which is recessed downwards and allows the limiting posts to be inserted. This magnetic shaft is mounted on the keyboard's circuit board, which has a Hall element positioned opposite the magnet. When an external force is applied to the guide core and pressed, the guide core moves the magnet downwards, compressing the return spring. The Hall element on the circuit board senses the magnet and transmits a signal. Simultaneously, the guide core moves a limiting post into the limiting groove of the limiting boss. Under the limiting action of the limiting post and the limiting groove, the guide core can only move vertically and radially, thus causing the magnet on the guide core to move vertically up and down. This allows the Hall element to more accurately sense the movement of the magnet, thereby improving the sensing accuracy of the magnetic shaft. By setting the limiting boss to an upward protruding structure and the limiting groove to be set in the middle of the limiting boss and downward recessed structure, the distance between the limiting post and the limiting boss is smaller, which makes it easier for the limiting post to be placed into the limiting groove of the limiting boss, thereby limiting the movement stroke of the guide core and facilitating the cooperation between the components.

Detailed Implementation

[0028] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods of this utility model will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0029] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Example 1

[0033] Please refer to Figures 1 to 7This utility model provides a high-transmittance and high-stability magnetic shaft, including a base 1, an upper cover 2 disposed on the base 1, a guide core 3 movably disposed between the base 1 and the upper cover 2, a reset spring 4 disposed between the guide core 3 and the base 1, and a magnet 5 disposed in the lower end of the guide core 3. It also includes limiting posts 31 symmetrically disposed on the lower end surface of the guide core 3 and protruding downwards. The inner wall of the base 1 is symmetrically formed with limiting bosses 11 that are raised upwards and directly opposite the limiting posts 31. A limiting groove 12 is formed in the middle of the limiting bosses 11 that is recessed downwards and allows the limiting posts 31 to be inserted.

[0034] This magnetic shaft is mounted on the keyboard's circuit board, which has a Hall element directly opposite the magnet 5. When an external force is applied to the guide core 3 and pressed, the guide core 3 moves the magnet 5 downwards, compressing the return spring 4. The Hall element on the circuit board senses the magnet 5 and transmits a signal. Simultaneously with the pressing of the guide core 3, the guide core 3 moves the limiting post 31, which is embedded in the limiting groove 12 of the limiting boss 11, and moves up and down within the limiting groove 12. Under the limiting action of the limiting post 31 and the limiting groove 12, the guide core 3 can only move vertically and radially, thus causing the magnet 5 on the guide core 3 to move vertically up and down. This allows the Hall element to more accurately sense the movement of the magnet 5, thereby improving the sensing accuracy of this magnetic shaft. The entire process is smooth and stable. By setting the limiting boss 11 to an upward protruding structure and the limiting groove 12 to be set in the middle of the limiting boss 11 and downward recessed structure, the distance between the limiting post 31 and the limiting boss 11 is smaller, which makes it easier for the limiting post 31 to be placed into the limiting groove 12 of the limiting boss 11, thereby limiting the movement stroke of the guide core 3 and facilitating the cooperation between the components.

[0035] Preferred, such as Figures 2 to 5 As shown, in order to further limit the stroke of the guide core 3, a limiting guide rail 13 with an overall I-shape is formed on the inner wall of the base 1, located outside the limiting protrusion 11. A limiting slider 32 that slides on the limiting guide rail 13 is formed on the outer wall of the guide core 3. The limiting slider 32 is placed on the limiting guide rail 13 and is driven by the guide core 3 to slide within the limiting guide rail 13. The limiting guide rail 13 is set vertically and radially, so that the limiting slider 32 sliding within the limiting guide rail 13 is also restricted to vertical up and down movement. Thus, the guide core 3 can only move vertically and radially. The magnet 5 set on the guide core 3 is driven to move vertically up and down at the same time, which helps the Hall element to more accurately sense the changes of the magnet 5, thereby improving the sensing accuracy of the magnetic shaft.

[0036] The keyboard's circuit board has RGB lights, such as... Figure 3and Figure 5 As shown, in order to produce better lighting effects on the RGB lights on this magnetic axis, light-giving grooves 14 are symmetrically formed on the base 1 to allow light to pass through. This allows the RGB lights on the circuit board to pass through the light-giving grooves 14 and illuminate other structures of the magnetic axis through the base. Through refraction and diffusion of other structures of the magnetic axis, the light can be diffused to the entire axis, greatly improving the uniformity and coordination of the lighting, ensuring the lighting effect of the keyboard, and improving the user experience.

[0037] Preferred, such as Figure 1 and Figure 3 , Figure 6 As shown, to improve the lighting effect of the RGB lights, a light guide column 6, shaped like a "∟" and embedded in the light clearance groove 14, is provided between the top cover 2 and the base 1. The lower end of the light guide column 6 is embedded in the light clearance groove 14, and the upper end of the light guide column 6 is fastened to the side wall of the base, thereby achieving stable installation of the light guide column 6. The light emitted by the RGB lights enters the light guide column 6 and is effectively guided and dispersed to various parts of the switch by the light guide column 6, so that the light covers most of the switch, greatly improving the uniformity and coordination of the lighting, ensuring the lighting effect of the keyboard, and improving the user experience.

[0038] Preferably, the RGB lights are also in two sets, respectively positioned below the light clearance slot 14 on the circuit board, so that the light emitted by the RGB lights is more uniform and symmetrical, covering most of the switch area, greatly improving the uniformity and coordination of the light, ensuring the lighting effect of the keyboard, and improving the user experience.

[0039] Preferred, such as Figure 3 As shown, a light-yielding part 21 is formed on the upper cover 2, which communicates with the light-yielding groove 14. The top of the light guide column 6 passes through the light-yielding part 21 of the upper cover 2, so that the light guide column 6 can better guide and emit light, further improve the uniformity and coordination of the light, ensure the lighting effect of the keyboard, and improve the user experience.

[0040] To ensure the light guide post 6 is stably installed between the upper cover 2 and the base 1, as follows: Figure 3 and Figure 7As shown, a light guide fixing block 61 is formed on each side of the light guide post 6, protruding outward and with its lower end face fastened to the upper end face of the side wall of the base 1. Light guide fixing grooves 22 for the light guide fixing blocks 61 to be embedded are formed on both sides of the lower end face of the side wall of the upper cover 2. After the lower end of the light guide post 6 is placed into the light clearance groove 14, the lower end face of its light guide fixing block 61 is fastened to the upper end face of the side wall of the base 1. At the same time as the upper cover 2 is fastened to the base 1, the light guide fixing groove 22 of the upper cover 2 is aligned with the light guide fixing block 61 on the light guide post 6 and pressed down, so that the light guide fixing block 61 is placed into the light guide fixing groove 22 and is simultaneously fixed in the light guide fixing groove 22 by the force of the upper cover 2 fastening to the base 1, thereby achieving stable installation of the light guide post 6 and preventing the light guide post 6 from shifting or falling off during use, which would lead to poor light transmission effect.

[0041] Preferred, such as Figure 3 and Figure 7 As shown, in order to better insert the light guide post 6 into the light clearance groove 14, outwardly protruding arc-shaped protrusions 62 are formed on both sides of the outer wall of the light guide post 6. The outer wall of the arc-shaped protrusions 62 presses against the inner wall of the light clearance groove 14, thereby reducing the contact area between the light guide post 6 and the light clearance groove 14, and further reducing the friction between the light guide post 6 and the light clearance groove 14, so that the light guide post 6 can be better inserted into the light clearance groove 14, thereby improving the production efficiency of this magnetic shaft.

[0042] In order to better disperse the light, such as Figure 3 and Figure 7 As shown, the upper end of the light guide post 6 is a semi-circular arc shape or a sloping structure extending from the lower outer edge to the upper inner edge. The semi-circular arc shape allows light to diffuse at a wider angle, ensuring the light covers most of the switch body, significantly improving the uniformity and coordination of the lighting, ensuring optimal keyboard lighting effects, and enhancing the user experience. The sloping structure extending from the lower outer edge to the upper inner edge reflects light better along the sloping surface, achieving good lighting effects and enhancing the user experience. Both structures can be configured according to actual needs and can be freely interchanged on the magnetic switch to meet different user requirements, thereby improving the practicality of the magnetic switch. Of course, it can also be configured with other structures such as a square shape, depending on the specific requirements.

[0043] Preferred, such as Figure 6 and Figure 7 As shown, the inclined structure also has several upward-protruding or inward-recessed rhombuses. When light passes through the light guide post, it is refracted by different surfaces of the rhombuses, thus covering most of the axis, greatly improving the uniformity and coordination of the light, ensuring the lighting effect of the keyboard, and improving the user experience.

[0044] Preferably, in order to improve the lighting effect, the top cover 2 is a transparent top cover 2 or a semi-transparent top cover 2, so that when the light passes through the light guide post 6, it is diffused and refracted onto the transparent or semi-transparent top cover 2, and can be better penetrated to reach the keycap, forming a good lighting effect, greatly improving the uniformity and coordination of the light, and improving the user experience.

[0045] Example 2

[0046] In the first embodiment, the structure of the magnetic shaft was described. This embodiment mainly focuses on the differences from other embodiments; identical structures will not be repeated in this embodiment.

[0047] like Figure 8 As shown, the main difference between Embodiment 2 and Embodiment 1 is that this embodiment does not require the use of light guide pillars 6. The upper cover 2 is a transparent or semi-transparent upper cover 2. The light emitted from the RGB lights shines directly onto the transparent or semi-transparent upper cover 2 through the light clearance groove 14, and is guided and dispersed by the transparent or semi-transparent upper cover 2, thereby covering most of the switch body. This significantly improves the uniformity and coordination of the lighting, ensuring the keyboard's lighting effect and improving the user experience. This structure effectively saves on the structure of light guide pillars 6, making the entire switch body structure simpler, effectively improving production efficiency and saving production costs.

[0048] Preferably, in order to better allow light to emanate outwards, such as Figure 8 As shown, the upper cover 2 has a light refraction part 23 that is recessed inward and has a right-angle shape at the position opposite to the light clearance groove 14. Its recessed and right-angle structure allows the RGB light to be refracted at the right angle to different directions of the keycap when it reaches the light refraction part 23, so that the light covers most of the switch body, greatly improving the uniformity and coordination of the light, ensuring the lighting effect of the keyboard, and improving the user experience.

[0049] It should be noted that the high-transmittance and high-stability magnetic shaft disclosed in this utility model is an improvement on the specific structure, but the specific control method is not the innovation of this utility model. The RGB lights, magnets, Hall sensors, circuit boards, and other components involved in this utility model can be general standard parts or components known to those skilled in the art. Their structures, principles, and control methods are all known to those skilled in the art through technical manuals or conventional experimental methods.

[0050] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, other structures obtained by using the same or similar technical features as the above embodiments of the present utility model are all within the protection scope of the present utility model.
