[0001] This application relates to the field of keyboard design, specifically to a magnetic axis keyboard and positioning plate that can enhance the lighting area. Background Technology

[0002] Today, more and more computer users and gamers are demanding higher levels of comfort, feel, and quality from their computers. Keyboards, as a computer peripheral, are also undergoing changes; mechanical keyboards are no longer just a favorite among enthusiasts, but are increasingly being recognized by those who value quality and feel.

[0003] For magnetic switch keyboards, the use of Hall effect sensors beneath the keycaps to enhance sensitivity gives them advantages such as fast response, low power consumption, and ease of maintenance. However, with increasing aesthetic demands, magnetic switch keyboards may interfere with the illumination of the LED lights beneath the keyboard. The current design of individual LEDs cannot adequately illuminate the entire keycap, affecting the visual effect and reducing the user experience. Utility Model Content

[0004] Therefore, a novel keyboard design is needed to solve the problem of keyboard lighting in the existing technology.

[0005] To achieve the above objectives, the inventors provide a magnetic axis keyboard, including a main control circuit board and a Hall sensor and LEDs electrically connected to the circuit board. In some embodiments, a first Hall sensor is provided in a first region below a first keycap. A first tangent line passing through the center of the first Hall sensor and its vertical plane divide the first region into a region with at least one LED and another region without an LED. A light guide groove is also provided in the first region, which can guide the light from the LED to the other region without an LED or the region below another keycap.

[0006] In one embodiment of this application, two or more LED beads are provided on one side of the first axis.

[0007] In one embodiment of this application, a second Hall sensor is provided in a second region below the second keycap. A second tangent line passing through the center of the second Hall sensor and its vertical plane divide the second region into a region with at least one LED and another region without an LED. The light guide groove is used to guide the light from the LED below the first keycap to the region without an LED below the second keycap.

[0008] In one embodiment of this application, the first keycap and the second keycap are adjacent keycaps.

[0009] In one embodiment of this application, the color of the LED below the first keycap is different from the color of the LED below the second keycap.

[0010] In one embodiment of this application, it further includes: a positioning plate, wherein a light guide groove is provided on the positioning plate.

[0011] In one embodiment of this application, the shape of the light guide groove is a bend, an arc, or a semi-circular ring.

[0013] A positioning plate for a magnetic axis keyboard has a shaft hole corresponding to a first Hall sensor located below a first keycap. A lamp hole is provided on one side of the shaft hole. The positioning plate also has a light guide groove that extends from the position below the corresponding first keycap to the position below the corresponding second keycap on the light guide plate.

[0014] In one embodiment of this application, a shaft hole corresponding to a first Hall sensor is provided below the first keycap. A lamp hole is provided on one side of the shaft hole, and a light guide groove is also provided on the positioning plate. The light guide groove extends from the lamp hole to the part of the shaft hole on the other side where no lamp hole is provided.

[0035] This utility model provides a magnetic shaft keyboard, including a main control circuit board and a Hall sensor and LEDs electrically connected to the circuit board. A first Hall sensor 11 is disposed in a first region 301 below the first keycap. A first tangent AA' passing through the center of the first Hall sensor 11 and its vertical plane divide the first region 3011 into a region P with at least one LED 2 and another region P1 without LEDs 2. A light guide groove 4 is also disposed in the first region 301, which guides the light from the LED 2 to the other region without LEDs 2 or to other regions below the keycaps. Here, the Hall sensor, also known as a Hall switch, is a circuit element that outputs an electrical signal to the circuit through the Hall effect. Our technical solution does not limit the type of Hall sensor used. The center of the Hall sensor represents the geometric center or centroid of the Hall sensor's projection in the vertical direction. The projection of the Hall sensor in the vertical direction does not necessarily have to be radially symmetrical or centrally symmetrical; only a general center is required. For example, generally, the projection of the Hall sensor in the vertical direction is rectangular, such as... Figure 1 As shown, the first tangent is a horizontal line, and its angle can be arbitrary, as long as it passes through the center of the projection. If any first tangent and its corresponding longitudinal section divide the space below the keycap in two, resulting in one side having a light and the other not, it easily leads to insufficient lighting under current technology. Figure 1 By employing a light guide groove 4, the other side, which does not have LED beads 2, can also be illuminated. The light guide groove 4 can be a hollow structure on the positioning plate. To briefly describe the keyboard's layered structure, it can include, from bottom to top, a bottom shell, a circuit board (with LED beads 2 and Hall switches positioned above the circuit board), a positioning plate 3, and keycaps. The Hall sensor and its trigger switch typically penetrate the positioning plate 3 and connect to the keycaps. Since LED beads 2 can illuminate the space between the circuit board and the positioning plate 3, when the light guide groove 4 extends to another area below the keycaps, LED beads 2 can also illuminate that other side. Figure 2 As shown, the light guide groove 4 can direct the light from the LED 2 to the area below the adjacent keycap. If the adjacent keycap does not have an LED 2, it can achieve the technical effect of one LED 2 illuminating two or more keycaps. If the adjacent keycap has an LED 2, it can achieve the technical effect of auxiliary lighting to make the adjacent keycaps brighter.

[0036] In some basic embodiments, only one LED bead 2 can be placed under the lamp cap, and the illumination of the LED bead 2 can be improved through the light guide groove 4. Figure 3In some embodiments shown, two or more LEDs 2 are arranged on one side of the first axis. These two or more LEDs 2 are not symmetrically arranged on both sides of the Hall sensor, but rather concentrated on the same side. The light is guided to the other side of the Hall sensor via the light guide groove 4, allowing the light to illuminate a wider area. The same principle applies to schemes with three or more LEDs 2. Compared to the case where two or more LEDs 2 are evenly distributed, LEDs 2 arranged on the same side can reduce wiring length, wiring difficulty, and short-circuit risk, thereby increasing the lifespan of the circuit board.

[0037] Please continue reading below. Figure 4 A second Hall sensor 12 is disposed in the second region 302 below the second keycap. A second tangent line BB' passing through the center of the second Hall sensor 12 and its vertical plane divide the second region 302 into an area with at least one LED bead 2 and another area without an LED bead 2. The light guide groove 4 is used to guide the light from the LED bead 2 below the first keycap to the area without an LED bead 2 below the second keycap. The vertical projection of the Hall sensor is rectangular, and the second tangent line BB' is a horizontal line with an arbitrary angle, as long as it passes through the center of the Hall sensor projection. As long as any second tangent line and its vertical plane divide the space below the keycap in two, resulting in a situation where one side of the space below the second keycap is lit while the other side is not, it is easy to cause insufficient lighting under the existing technology. By using the light guide groove 4, the other side without an LED bead 2 can also be illuminated through different keycaps. The light guide groove 4 here can be a hollow structure on the positioning plate 3. By setting the light guide groove 4 between adjacent keycaps, the technical effect of illuminating the area without an LED bead 2 can be better achieved.

[0038] In one embodiment of this application, the first keycap and the second keycap are adjacent keycaps. In other embodiments, the first keycap and the second keycap are non-adjacent keycaps. By analogy, by setting the light guide groove 4, the light of the LED bead 2 can be shared between keycaps that are any distance apart on the keyboard, which can better achieve the effect of saving the number of LED beads 2.

[0039] In one embodiment of this application, the color of the LED 2 located under the first keycap is different from the color of the LED 2 located under the second keycap. The LED 2 located under the first keycap can guide the light to the area under the second keycap through the light guide groove 4. This structure can be combined with light modulation commands to achieve more complex multi-color control effects.

[0040] Some examples of this utility model's magnetic axis keyboard also include a positioning plate 3, on which a light guide groove 4 is provided. The light guide groove 4 can also be designed by adding transparent materials, such as glass, plastic, or transparent fiberglass, to the hollowed-out portion. The transparent material in the light guide groove 4 can reduce light attenuation during the light guiding process by utilizing the principles of refraction and total internal reflection. Ultimately, this achieves the technical effect of guiding the light beam to the far end of the light guide groove 4.

[0041] In some embodiments of this application, please refer to Figures 1-5 The light guide groove 4 is shaped like a bend, an arc, or a semi-circular ring. The Hall switch has volume in the vertical direction. The light emitted by the LED 2 is originally blocked by the Hall switch and cannot illuminate the area behind it. However, through the irregular design of the light guide groove 4, it can bypass the Hall switch and illuminate the area where the LED 2 is not originally located. This design achieves a better technical effect of guiding the light path to the area where the LED 2 is not located.

[0042] Optionally, the lamp bead 2 is an LED lamp bead. By using LED lamp beads, the energy consumption of the lamp bead 2 can be reduced, the light intensity can be improved, and the light concentration can be improved.

[0043] Please continue reading. Figures 1-5 All of these can be considered as partial design schematic diagrams of the positioning plate 3. This solution also provides an illustration of a positioning plate 3 for a magnetic axis keyboard. Below the first keycap, a shaft hole corresponding to the first Hall sensor 11 is provided. A lamp hole is provided on one side of the shaft hole. The positioning plate 3 also has a light guide groove 4, extending from below the first keycap to below the second keycap on the positioning plate 3. The keyboard's hierarchical structure may include, from bottom to top, a bottom shell, a circuit board (with the LED 2 and Hall switch positioned above the circuit board), a positioning plate 3, and keycaps. The Hall sensor and its trigger switch generally pass through the shaft hole on the positioning plate 3 and connect to the keycap. Here, the Hall sensor, also called a Hall switch, is a circuit element that outputs an electrical signal to the circuit through the Hall effect. Our technical solution does not limit the type of Hall sensor used. The center of the Hall sensor represents the geometric center or centroid of the Hall sensor's projection in the vertical direction. The Hall sensor's projection in the vertical direction is not necessarily radially symmetric or centrally symmetric; only a general center is required. For example, generally, the Hall sensor's projection in the vertical direction is rectangular, such as... Figure 1 As shown, the first tangent is a horizontal line, and its angle can be arbitrary, as long as it passes through the center of the projection. If any first tangent and its corresponding longitudinal section divide the space below the keycap in two, resulting in one side having a light and the other not, it easily leads to insufficient lighting under current technology. The light guide groove 4 design described above can effectively illuminate the area of ​​the other keycap where no LEDs 2 are installed.

[0044] In other embodiments, a shaft hole corresponding to the first Hall sensor 11 is provided below the first keycap. A lamp hole is provided on one side of the shaft hole, and a light guide groove 4 is also provided on the positioning plate 3. The light guide groove 4 extends from the lamp hole to the part on the other side of the shaft hole where no lamp hole is provided. Through the above-mentioned design of the light guide groove 4, the area under the first keycap where no LED bead 2 is provided can be effectively illuminated.

[0045] In some specific design embodiments on the positioning plate 3, the aforementioned embodiments can be integrated. The positioning plate 3 does not necessarily need to have a visible boundary of the "area below the keycap". This is only for the convenience of description.

[0046] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
