Description

Metal key cap and illuminated button including the metal key cap

The present invention relates to a metal keycap and an illuminated key comprising the metal keycap, and in particular to a metal keycap capable of transmitting light.

As the user's use requirements increase, the keyboard is no longer merely providing a simple input peripheral device, and the function and aesthetics of the auxiliary input are also required. At present, a keyboard with a backlight is provided on the market, which allows the user to clearly understand the position of the button under the backlight, without input errors or sensory aesthetics.

Please refer to FIG. 1. FIG. 1 is a partial cross-sectional view showing the prior art illuminated keyboard 1. The illuminated keyboard 1 includes a backlight 18 and a plurality of buttons 10 mounted on the backlight 18. In Fig. 1, only one button 10 is shown as a representative. The illuminated keyboard 1 includes a substrate 11, a membrane switch 12, a keycap 14, a scissor support device 16, an elastic actuator 17, and a backlight 18. The scissor-type supporting device 16 is mounted on the substrate 11, and the substrate 11 is formed with a structure for assisting the fixing of the scissor-type supporting device 16. The keycap 14 is mounted on the scissor support device 16. The scissor support device 16 limits the vertical movement of the keycap 14 relative to the membrane switch 12 to move between the undepressed position and the depressed position.

The elastic actuator 17 is disposed on the membrane switch 12. As shown in Fig. 1, the general elastic actuator 17 is a resilient dome and has a considerable height. The top 172 of the resilient dome 17 abuts against the lower surface 140 of the keycap 14. An external force is applied to the keycap 14 to move the keycap 14 toward the membrane switch 12. The elastic actuator 17 is deformed as the key cap 14 moves, The actuation of the membrane switch 12 is triggered.

The backlight device 18 includes a light guide plate 180, a light source 182, and a reflective structure 184. The light guide plate 180 has a light incident side 1802, a front surface 1804, and a back surface 1806. The light incident side 1802 serves as a light incident surface for the light source 182 to emit light.

The light source 182 is disposed adjacent to the light guide plate 180, that is, adjacent to the side edge 1802 of the light guide plate 180. The light source 182 is configured to emit light, enter the light guide plate 180 and conduct within the light guide plate 180. The reflective structure 184 is disposed on the back surface 1806 of the light guide plate 180. The reflective structure 184 is configured to guide the light that is directed toward the reflective structure 184 to the front surface 1804 of the light guide plate 180 and further from the front surface 1804 of the light guide plate 180. The backlight device 18 also includes a reflective sheet 186. The reflective sheet 186 is attached to the back surface 1806 of the light guide plate 180 to assist in reflecting the light conducted in the light guide plate 180.

The substrate 11 has a first light transmissive region 112, and the key cap 14 has a second light transmissive region 142 thereon. In the actual product design, the first light transmitting region 112 may be a through hole. When the light is led out from the light guide plate 180, the first light transmitting region 112, the membrane switch 12, the elastic actuator 17, and the second light transmitting region 142 of the key cap 14 are sequentially passed through. The elastic actuator 17 can be constructed of a transparent or translucent material such that light can pass directly through the elastic actuator 17 to reach the second light transmissive region 142 of the keycap 14, or the light can be diffused by the elastic actuator 17 to The light around the keycap 14 and the light passing through the second light transmissive region 142 are softer. If the second light transmitting region 142 corresponds to a symbol or a letter on the key cap 14, the symbol or letter region represented by the second light transmitting region 142 is allowed. Therefore, when the ambient light source is weak, the illuminated keyboard 1 allows different keys to be easily distinguished, and is convenient for the user to input data. It should be noted that if the substrate 11 is made of a light transmissive material, the first light transmitting region 112 may not be in the form of a through hole. The region of the substrate 11 outside the first light-transmissive region 112 is also allowed to pass through a portion of the light to provide a backlighting effect relative to the first light-transmitting region 112.
