[0031] Firstly, please refer to Figure 1 and Figure 2 This application provides a button 100, including a PCB board 10 and a key switch 20.
[0032] The PCB board 10 is provided with at least two light-emitting elements 11; the key shaft 20 includes a shaft seat 21 and a shaft cover 22 covering the shaft seat 21. The shaft seat 21 is fixed on the PCB board 10. Each light-emitting element 11 is symmetrically arranged with the central axis of the shaft seat 21 as the center. Furthermore, the shaft seat 21 is provided with a clearance groove 21a for accommodating the corresponding light-emitting element 11.
[0033] Understandably, the PCB board 10 is the carrier of the button 100, used to provide support for the key shaft 20 and related electrical connections, and to provide corresponding power to the light-emitting element 11.
[0034] Here, the light-emitting element 11 can be a monochrome LED, a white LED, or a multi-chip integrated LED.
[0035] The key switch 20 is the main body of the key 100 and is also the part connected to the keycap. The switch seat 21 is directly connected to the PCB board 10, and the switch cover 22 covers the switch seat 21 to form a space for accommodating the pressing switch.
[0036] At least two light emitters 11 are symmetrically arranged about the central axis of the bearing 21 to form symmetrical emission beams in a direction perpendicular to the PCB board 10, thereby increasing the light intensity. At the same time, in order to create a clearance at the height of the PCB board 10, clearance slots 21a are formed at corresponding positions on the bearing 21 to avoid spatial interference between the light emitters 11 and the bearing 21 in the height direction of the PCB board 10.
[0037] For example, there are two light-emitting elements 11, which are arranged on opposite sides of the bearing seat 21. Here, the bearing seat 21 is projected as a square or near-square shape on the PCB board 10, so there are two sides arranged opposite each other. In this way, the two light-emitting elements 11 are symmetrically arranged about the central axis of the bearing seat 21, and are located at the clearance groove 21a on the corresponding side of the bearing seat 21.
[0038] For example, there are four light-emitting elements 11, and each light-emitting element 11 is arranged in pairs. The light emitted by each pair is located on opposite sides of the bearing 21. Similarly, the bearing 21 is projected as a square or near-square shape on the PCB board 10, so there are opposite sides. In this way, the four light-emitting elements 11 are symmetrically arranged about the central axis of the bearing 21, and are located at the clearance groove 21a on the corresponding side of the bearing 21.
[0039] The button 100 provided by this utility model has at least two light-emitting elements 11 on the PCB board 10, and each light-emitting element 11 is symmetrically arranged with the central axis of the shaft seat 21 as the center, thereby increasing the light emission angle of the key shaft 20 during use and improving the light emission effect of the button 100.
[0040] Please refer to Figure 1 and Figure 2 In some embodiments, a mounting groove 21b is provided on the shaft seat 21 in the height direction. The mounting groove 21b passes through the shaft seat 21 and is connected to the clearance groove 21a. The button 100 includes a light guide 23, which is placed in the mounting groove 21b and corresponds to the light emitter 11.
[0041] Understandably, the mounting slot 21b is used to allow the light beam emitted by the light-emitting element 11 to pass through and to emit in a direction perpendicular to the PCB board 10. At the same time, the light guide 23 guides the light beam emitted by the light-emitting element 11 out of the bearing seat 21.
[0042] Please refer to Figure 1 and Figure 2 In some embodiments, the shaft seat 21 is snapped into connection with the shaft cover 22. The shaft cover 22 includes a cover body 221 and a snap-fit arm 222 disposed on the cover body 221. The shaft seat 21 is provided with a snap-fit groove (not shown in the figure) corresponding to the snap-fit arm 222.
[0043] Understandably, during installation, the cover 221 is pressed so that the snap-fit arm 222 snaps into the corresponding snap-fit groove.
[0044] For example, the cover 221 has four sides, and two of them correspond to each other. The number of snap-fit arms 222 is four, where two snap-fit arms 222 form a group, and every two snap-fit arms 222 are provided on one side, and two snap-fit arms 222 are provided on the corresponding side.
[0045] Please refer to Figure 1 and Figure 2 In some embodiments, the cover 221 is provided with a receiving groove 22a, which is connected to the mounting groove 21b, and the light guide 23 extends into the receiving groove 22a.
[0046] Understandably, the receiving groove 22a is provided for the light-emitting element 11 in the mounting groove 21b to extend outward, so as to further extend the light-emitting element 11 outward.
[0047] Please refer to Figure 1 and Figure 2 In some embodiments, the light guide 23 includes a first light guide portion 231 disposed in the mounting groove 21b and a second light guide portion 232 connected to the first light guide portion 231, the second light guide portion 232 being placed in the receiving groove 22a.
[0048] Understandably, the light guide 23 is divided into two parts, specifically a first light guide 231 and a second light guide 232. The first light guide 231 and the second light guide 232 are connected to each other. The first light guide 231 is housed in the mounting groove 21b, while the second light guide 232 is housed in the receiving groove 22a.
[0049] Please refer to Figure 1 and Figure 2 In some embodiments, there are two first light guides 231, and each first light guide 231 is provided corresponding to the light emitter 11.
[0050] Understandably, in this embodiment, two first light guides 231 are arranged side by side on the second light guide 232.
[0051] Please refer to Figure 1 and Figure 2 In some embodiments, the cover 221 has a first inclined surface 221a, and the second light guide portion 232 has a light guide slope 232a, which is flush with the first inclined surface 221a.
[0052] Understandably, the first inclined surface 221a is the exposed surface of the cover 221, and the light guide inclined surface 232a is also the exposed surface of the second light guide part 232. That is, after the light beam passes through the first light guide part 231 and the second light guide part 232, it is emitted to the outside through the light guide inclined surface 232a.
[0053] Please refer to Figure 1 and Figure 2 In some embodiments, the key shaft 20 includes a pressing shaft body 24, which is slidably connected to the shaft cover 22 in the height direction of the shaft seat 21.
[0054] Understandably, the pressing shaft 24 is the movable part of the button 100. The pressing shaft 24 can slide up and down relative to the shaft seat 21 in its height direction to realize signal input.
[0055] Please refer to Figure 2 In some embodiments, the key shaft 20 includes a spring 25 disposed within the shaft seat 21 and abutting against the pressing shaft body 24.
[0056] Secondly, embodiments of this application provide a keyboard, including the aforementioned key 100.
[0057] The keyboard of this invention, based on the aforementioned key 100, can achieve a better lighting effect.
[0058] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
