Description

Technical Field

[0001] This utility model relates to the field of keyboard keys, specifically to an illuminated key and a keyboard. Background Technology

[0002] Existing illuminated buttons generally employ a structure where LED beads are mounted on a circuit board, and then an independent light guide column or light guide sheet is installed on the base. The light emitted by the LED beads is guided by the light guide and shines through a specific area of ​​the button axis.

[0003] This structure has several obvious drawbacks: First, the light needs to undergo multiple refractions and long-distance transmission, resulting in significant light loss and insufficient brightness of the transmitted light; second, the light emission is usually limited to the local area where the light guide is located, resulting in uneven light distribution and obvious differences in brightness; third, if multiple LEDs are arranged to achieve a more uniform light effect, it is very inconvenient to arrange the circuit and install multiple LEDs in the limited space of the base plate, which increases the design and manufacturing difficulty. Utility Model Content

[0004] To address the aforementioned problems, this utility model aims to provide an illuminated button to solve the issues of insufficient brightness, uneven light distribution, and inconvenience in arranging multiple LEDs in existing technologies.

[0005] To achieve this technical objective, the present invention provides a light-emitting button, comprising a PCB base plate and a button mounted on the PCB base plate. The button includes a housing, a push shaft, and a spring-loaded reset component. The button also includes a light-emitting outer shell disposed on the upper part of the housing. A light-emitting element is disposed within the light-emitting outer shell, and an electrical connection portion extends from the light-emitting outer shell toward the PCB base plate, with the end of the electrical connection portion forming an electrical pin. A pin terminal is disposed on the PCB base plate. When the light-emitting outer shell is mounted to the button housing, its electrical pin is inserted into the pin terminal to achieve electrical connection.

[0006] Preferably, the light-emitting outer shell is a cover-like structure with a central through hole at the top, and its sidewalls extend downward from the edge of the central through hole.

[0007] Preferably, the housing includes a base and a top cover, the push shaft is movably disposed between the top cover and the base, and the top cover limits the upward movement of the push shaft.

[0008] Preferably, the light-emitting shell has connecting structures on both sides, and the top cover has corresponding through holes. The connecting structures pass through the through holes and cooperate with the base below to fix the light-emitting shell to the shell.

[0009] Preferably, the light-emitting shell is provided with a connecting structure, and the light-emitting shell is fixed to the base through the connecting structure.

[0010] Preferably, the electrical connection portion is integrally formed with the connection structure and extends downward to form the electrical pin.

[0011] Preferably, the base has a clearance hole for the electrical connection part to pass through.

[0012] Preferably, the housing is a base, and the push shaft is movably disposed between the light-emitting housing and the base, with the light-emitting housing limiting the upward movement of the push shaft.

[0013] Preferably, the light-emitting element is an RGB LED bead, and multiple RGB LED beads are evenly distributed along the light-emitting outer shell.

[0014] This utility model also discloses a keyboard, including illuminated keys as described in any of the above.

[0015] The beneficial effects of this utility model are: by integrating the light-emitting element into the outer light-emitting shell, this utility model fundamentally changes the light-emitting method of the button, achieving a bright and uniform light-emitting effect around the edges. At the same time, it has a clever structure, is easy to install, and has high practical value and commercial prospects. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. To provide a clear and complete description of the technical solution, the following embodiments are selected for illustration; these embodiments are only some embodiments of the present invention; other embodiments obtained based on this application without creative effort are all within the scope of protection of the present invention.

[0023] In the following embodiments, it should be noted that the terms "upper," "lower," "left," "right," "inner," "outer," "top / bottom," etc., are all based on the orientation or positional relationship shown in the accompanying drawings and are only for the purpose of clearly describing this embodiment. They do not indicate or imply that the device or element referred to must have a specific orientation, and therefore should not be construed as a limitation of this application. At the same time, the terms "first" and "second" in the embodiments are only used for descriptive purposes and do not represent an indication or implication of relative importance.

[0024] like Figure 1-5 As shown, the specific embodiment of this utility model is a light-emitting button, which mainly consists of a light-emitting shell 1, a button shaft 2, an upper cover 3, a base 4, an elastic reset component 5 (a reset spring in this embodiment) and a PCB base plate 6.

[0025] The push-button shaft 2 is movably mounted within the accommodating space formed by the snap-fit ​​of the upper cover 3 and the base 4. The elastic reset member 5 is sleeved on the guide post at the lower part of the push-button shaft 2 and supported between the push-button shaft 2 and the base 4, providing the push-button shaft 2 with a rebound force after being pressed.

[0026] The core improvement of this utility model lies in the light-emitting shell 1. The light-emitting shell 1 is made of a light-transmitting or semi-light-transmitting material, and its overall structure is a cover-like structure with a central through hole at the top. The side walls extend downward from the edge of the central through hole, and its shape is similar to a square keycap without a top cover. During assembly, the light-emitting shell 1 is fitted over the outside of the upper cover 3 from top to bottom, and the pivot 2 extends out of the upper cover 3 for the keycap to be installed.

[0027] On both sides of the luminous housing 1, connecting structures 11 (such as snap-fits or inserts) extend downwards. On both sides of the top cover 3, corresponding through holes 31 are provided. During assembly, the connecting structures 11 of the luminous housing 1 pass through the through holes 31 of the top cover 3, thereby achieving a reliable connection between the luminous housing 1 and the button body.

[0028] Inside the light-emitting housing 1, multiple RGB LEDs are integrated as light-emitting elements. These RGB LEDs are evenly distributed circumferentially along the sidewalls of the light-emitting housing 1, ensuring that light is emitted uniformly from all directions. By directly integrating the light-emitting elements (RGB LEDs) into the light-emitting housing that is fitted outside the top cover, light is emitted directly from the light-emitting housing around the hinge 2, eliminating the need for long-distance light guiding, resulting in low light loss and high brightness. Through the even distribution of multiple LEDs, a uniform light emission effect can be achieved from all angles, completely solving the problem of uneven light path in traditional structures.

[0029] An electrical connection portion is provided on one side of the connection structure 11. In a preferred embodiment, the electrical connection portion and the connection structure 11 are integrally formed, and the end of the electrical connection portion is an electrical pin 12. All RGB LEDs inside the light-emitting housing 1 are electrically connected to the electrical pin 12 through an internal circuit.

[0030] On the PCB base plate 6, a pin terminal 61 is provided corresponding to the position of each button. Simultaneously, a clearance hole 41 is provided at the corresponding position on the base 4. When the illuminated housing 1, along with the entire button, is installed downwards onto the PCB base plate 6, the electrical pin 12 on its side passes through the clearance hole 41 of the base 4 and inserts into the pin terminal 61 on the PCB base plate 6, achieving a stable electrical connection. The circuitry on the PCB base plate 6 can then power all the RGB LEDs on the illuminated housing 1 through this plug-in structure. Through a simple plug-in operation, the fixing and electrical connection of the illuminated housing 1 can be completed simultaneously, eliminating the step of soldering each LED individually onto the base plate, greatly simplifying the production and assembly process. Furthermore, since the LEDs are distributed on the illuminated housing rather than being limited by the base plate space, the number and arrangement of the LEDs can be designed more flexibly, making it easier to achieve more complex dynamic lighting effects and providing greater space for personalized button design.

[0031] In another embodiment of this application, the luminous outer shell 1 can also be used directly as the upper cover of the button to form the complete upper structure of the button, which is directly combined with the base to limit the movement of the button axis.

[0032] This application also protects a keyboard including a key area composed of multiple illuminated keys. Each illuminated key is connected to a pin terminal 61 on the main PCB board 6 of the keyboard via its electrical pin 12, and can emit uniform light.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any minor modifications, equivalent substitutions and improvements made to the above embodiments based on the technical essence of the present utility model should be included within the protection scope of the technical solution of the present utility model.
