Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1 to 3, in a preferred embodiment, the keyboard switch with enhanced light guiding effect of the present invention mainly comprises a base 1 and an upper cover 2, wherein the upper cover 2 can be fastened to the base 1 to form a cavity, and a button assembly 3 for pressing the keyboard switch is disposed in the cavity. The base 1 is made of plastic, and one side of the base 1 close to the bottom is provided with an avoiding hole 16, and the avoiding hole 16 is used for placing a light source which is not shown in the figure. It should be noted that, the existing keyboard light source usually adopts an LED patch, the LED patch is attached to the surface of the PCB, and when the keyboard switch is installed on the PCB, the LED patch is accommodated in the avoiding hole 16.

The upper cover 2 is made of transparent plastic, a light guide curved surface 4 is arranged on the inner side surface of the upper cover 2 facing the base 1, and the light guide curved surface 4 is opposite to the avoidance hole 16 up and down. When the light source in the avoiding hole 16 emits light, the light passes through the light guide curved surface 4 from bottom to top and is refracted at the light guide curved surface 4, so that the light is uniformly diffused, the irradiation range of the light is wider, and the brightness and the color are more uniform. It should be noted that the light guiding curved surface 4 is preferably an arch-shaped curved surface with an upward convex middle portion to ensure the light diverging effect.

The upper lid 2 includes a top surface 5 facing upward, and side surfaces 6 extending downward from the periphery of the top surface 5. Referring to fig. 4, in the first embodiment of the present invention, the top surface 5 of the embodiment is provided with a plurality of protrusions 7, in the present embodiment, the protrusions 7 are formed in a hemispherical shape, but not limited thereto, and in other embodiments, the protrusions 7 may be formed in a truncated cone shape or a cone shape. The protrusions 7 are arranged in an array on the top surface 5. Light enters the upper cover 2 after being dispersed by the light guide curved surface 4, and when the light is emitted from the top surface 5, the curved surface structure of the protrusion 7 can further disperse the light, so that the light is more uniform, and the lighting effect of the keyboard switch is softer and more attractive.

Referring to fig. 5, in a second embodiment of the present invention, in the present embodiment, the top surface 5 is provided with a light guiding groove 8, the light guiding groove 8 is formed into a groove-shaped structure recessed into the top surface 5, and the light guiding groove 8 is disposed in an inclined manner. Specifically, light guide groove 8 is for keeping away from the one end of dodging hole 16 to the one end that is close to dodging hole 16 downward sloping gradually, the effect of this design lies in, the light of light source transmission gets into behind upper cover 2 via leaded light curved surface 4, the inclined plane structure of light guide groove 8 makes partial light conduct to the one end of keeping away from dodging hole 16 along the inclined plane and jets out again, thereby the luminance of having avoided top surface 5 to be close to the one end of dodging hole 16 (be close to the one end of light source promptly) is too high, and the luminance of keeping away from the one end of dodging hole 16 is too dark defect, realize the even divergence of light.

Referring to fig. 6, a third embodiment of the present invention is different from the second embodiment in that the top surface 5 of the present embodiment is inclined, and the direction and the slope of the inclination are the same as those of the light guide groove 8. The design can avoid the problem that the light is blocked due to the large height difference between the edge of the top surface 5 and the light guide groove 8, so that the brightness is reduced.

Referring to fig. 7, in the fourth embodiment of the present invention, in the present embodiment, a plurality of light guide strips 9 are disposed on the side surface 6 of the upper cover 2, the light guide strips 9 are formed into a shape similar to a piano key protruding from or recessed into the side surface 6, and the light guide strips 9 are arranged in parallel on the side surface 6 and extend in the vertical direction. By arranging the light guide strip 9, light emitted by the light source can be uniformly emitted from the side surface 6 of the upper cover 2, and the intensity of the light is enhanced while the light projection range is increased. It should be noted that the light guide bar 9 in this embodiment can be combined with the top surface 5 structure in the first, second or third embodiment to obtain better light guide effect.

Referring again to fig. 1, the button assembly 3 includes a button 10, a spring 11, a torsion spring 12, a guide bar 13, an elastic contact piece 14, and a terminal 15. The upper cover 2 is provided with a through hole corresponding to the button 10, the upper end of the button 10 extends out of the upper cover 2 for pressing, the lower end of the button 10 is provided with a guide pillar, and the spring 11 is sleeved on the periphery of the guide pillar to provide resilience for the button 10. The elastic contact piece 14 and the terminal 15 are oppositely arranged, and the elastic contact piece 14 is controlled to be in contact with or disconnected from the terminal 15 by the up-and-down movement of the button 10. One side of the guide rod 13 is provided with a protrusion, the movable end of the torsion spring 12 is erected on the protrusion, the button 10 is pressed down to drive the movable end of the torsion spring 12 to move downwards and slide through the protrusion, and after the button is pressed in place, the torsion spring 12 rebounds and strikes to generate crisp sound, so that the hand feeling of the keyboard switch is improved.
