[0037] Reference Figures 1 to 7 A dual-LED backlight structure for a keyboard includes a housing 1 and a circuit board 2. The circuit board 2 is installed inside the housing 1. Multiple spindles are formed on the circuit board 2. Multiple first LED backlights 3 and multiple second LED backlights 4 are connected to the circuit board 2. The multiple first LED backlights 3 are located at the upper part of the multiple spindles, and the multiple second LED backlights 4 are located at the lower part of the multiple spindles. Mechanical shafts 6 are installed inside each of the multiple spindles. A horizontal groove is formed on one side of the housing 1. A storage mechanism 8 is provided inside the housing 1. A limiting mechanism 9 is provided on one side of the housing 1 to lock the storage mechanism 8. Multiple second LED backlights 4 are evenly distributed on the upper and lower parts of multiple axes, making the backlighting more uniform and avoiding the situation where a single LED backlight is paired with a dual-character key, resulting in one side of the characters being darker, thus affecting the user's keyboard experience. The locking of one side of the storage mechanism 8 can be released by rotating the limiting mechanism 9. At this time, the storage mechanism 8 can be taken out from the inside of the outer shell 1 through the horizontal groove. Finally, the replaced keycap 7 is placed inside the storage mechanism 8 for storage. Finally, the storage mechanism 8 is slid back into the inside of the outer shell 1 through the horizontal groove, and the limiting mechanism 9 is rotated in the opposite direction to limit the storage mechanism 8 and prevent it from sliding out of the inside of the outer shell 1.
[0038] To improve the uniformity of the backlight beam on the dual-character keycaps 7, refer to... Figure 1 The multiple first LED backlights 3 and multiple second LED backlights 4 are at the same distance from the multiple axis centers, so that the light emitted by the multiple first LED backlights 3 and multiple second LED backlights 4 is displayed more evenly on both sides of the multiple keycaps 7, improving the user's visual comfort and thus improving the user's user experience.
[0039] To improve the stability of the installation of multiple mechanical axes 6, refer to Figure 2 The housing 1 has a positioning plate 5 connected internally, and the positioning plate 5 is located on the upper part of the circuit board 2. Multiple mechanical switches 6 pass through the positioning plate 5 and extend to the bottom of the positioning plate 5. Through the positioning plate 5's position between the multiple mechanical switches 6 and the circuit board 2, it can support and fix the multiple mechanical switches 6, ensuring that the keycap 7 maintains vertical and stable movement when pressed, preventing the mechanical switches 6 from wobbling or tilting.
[0040] In order to facilitate the replacement of the plurality of keycaps 7, with reference to Figures 1 to 4 The outer surface of the plurality of mechanical shafts 6 is movably inserted with the keycaps 7. The "cross" block provided on the plurality of mechanical shafts 6 allows the "cross" sleeve inside the plurality of keycaps 7 to be easily sleeved outside the "cross" block or pulled out, thereby facilitating the replacement of the plurality of keycaps 7.
[0041] In order to store the plurality of keycaps 7, with reference to Figure 5 The storage mechanism 8 includes a collection box 801, a plurality of distribution grooves 802, and a pull handle 803. The collection box 801 is slidably connected to the bottom of the inner wall of the shell 1, and one side of the collection box 801 is adapted to the transverse groove. A plurality of distribution grooves 802 are equidistantly provided on the top of the collection box 801. The pull handle 803 is connected to one side of the collection box 801. Pulling the pull handle 803 drives the collection box 801 to slide out of the inside of the shell 1. At this time, the plurality of keycaps 7 removed from the keyboard are placed inside the distribution grooves 802. Finally, the other side of the collection box 801 is aligned with the transverse groove and slides into the inside of the shell 1, so that the collection box 801 can be stored and placed.
[0042] In order to limit the collection box 801, with reference to Figures 3 to 6 The limiting mechanism 9 includes a fixed rod 901 and a hinged handle 902. The fixed rod 901 is connected to one side of the shell 1, and the hinged handle 902 is hinged to the outer surface of the fixed rod 901. By rotating the hinged handle 902 by ninety degrees in the forward direction, the side of the collection box 801 is no longer shielded. By rotating the hinged handle 902 by ninety degrees in the reverse direction, the collection box 801 can be shielded again to prevent it from sliding out of the inside of the shell 1.
[0043] In order to facilitate the connection of the keyboard with external devices and to prevent dust from entering the plug-in part 10, with reference to Figure 3 One side of the shell 1 is connected with the plug-in part 10, and one side of the plug-in part 10 is movably inserted with a dust plug. Through the action of the plug-in part 10, the plug-in part 10 can be connected with other devices through the plug-in part 10. At the same time, when not in use, the dust plug is inserted into the inside of the plug-in part 10, so that it can be protected from dust.
[0044] In order to adjust the inclination angle of the keyboard, with reference to Figure 7 The bottom of the shell 1 is provided with a groove, and the inside of the two grooves is connected with a support leg 11. By rotating the two support legs 11, the two support legs 11 are turned to the outside of the two grooves. At this time, the two support legs 11 will support the part of the keyboard that is closer to the front, and the keyboard will be tilted, thereby completing the adjustment of the inclination angle of the keyboard.
[0045] Working principle: when the keyboard is used, one of the first LED backlights 3 and one of the second LED backlights 4 arranged on the circuit board 2 are used, and the two lamps are arranged on the upper and lower parts of one of the shafts, then the first LED backlight 3 cooperates with the second LED backlight 4 to display backlight, so that the double-character brightness of one of the keycaps 7 is displayed uniformly, thereby solving the problem that one of the keycaps 7 of the traditional double character is equipped with only one LED lamp, which causes one side character to be dark, affecting the user experience, after the user replaces one of the keycaps 7, the user rotates the articulated handle 902, the articulated handle 902 swings on the outer surface of the fixed rod 901, and then the side of the collection box 801 is released, at this time, the handle 803 is pulled to drive the collection box 801 to slide out from the inside of the shell 1 through the horizontal slot, at this time, the keycap 7 in the distribution slot 802 is taken out and installed on one of the mechanical shafts 6, at this time, one of the keycaps 7 is placed in the distribution slot 802, the handle 803 is pushed in the opposite direction, so that the collection box 801 is pushed into the inside of the shell 1 through the horizontal slot, at this time, the articulated handle 902 is reversely rotated and abuts against one side of the collection box 801, so that the collection box 801 is prevented from sliding out from the inside of the shell 1, and the collection and storage of the replaced keycap 7 can be completed.
[0046] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
