The light-emitting key 1 includes a translucent key cap 11, a frame 14 and an interlocking member 13. The light-transmitting keycap 11 is disposed above the base plate 12 and the light source circuit board 16. The frame 14 has a frame hollow-out portion 141, and the transparent keycap 11 is disposed in the frame hollow-out portion 141, so that the frame 14 can reduce the degree of light leakage at the periphery of the transparent keycap 11 to meet the aesthetic property.
In this embodiment, the switch circuit board 15 is provided with a switch portion 151, a first hollow portion 152, a first connecting member 1531, a second connecting member 1532 and an outer frame portion 154 corresponding to each light-emitting key 1. In practical operation, the transparent keycap 11 of each light-emitting key in the light-emitting keyboard has its own switch circuit board, and each switch circuit board has a switch portion, a first hollow portion, a first connecting member, a second connecting member, and an outer frame portion. The light source circuit board 16 has a second hollow portion 162. The first hollow portion 152 is located below the second hollow portion 162, and the first hollow portion 152 is located between the switch portion 151 and the outer frame portion 154.
The upper end of the linking member 13 is movably connected to the transparent key cap 11, the lower end of the linking member 13 passes through the light source circuit board 16 through the second hollow portion 162, and then passes through the switch circuit board 15 through the first hollow portion 152, so that the lower end of the linking member 13 can be movably connected to the bottom plate 12, and thus, the transparent key cap 11 can reciprocate up and down relative to the bottom plate 12 to trigger the switch portion 151.
Referring to fig. 11, fig. 11 is a schematic view of a first structure example of the switch circuit board of the light-emitting key of the present invention. The outer frame portion 154 has a light entry aperture 1541 that provides a light entry sidewall 15411. In the present embodiment, the first connecting member 1531 extends from the first side of the switch unit 151 to the outer frame 154 in a direction approaching the light incident sidewall 15411 to connect the first side of the switch unit 151 with the outer frame 154, and the second connecting member 1532 extends from the second side of the switch unit 151 to the outer frame 154 in a direction away from the light incident sidewall 15411 to connect the second side of the switch unit 151 with the outer frame 154.
Please refer to fig. 2, fig. 3, fig. 4 and fig. 6. In the embodiment, the light source circuit board 16 is located above the switch circuit board 15, the light source 161 capable of entering the light inlet hole 1541 is located below the light source circuit board 16, and the light source 161 extends to have the light outlet surface 1611, so as to emit the first light R1 to the light inlet sidewall 15411 of the light inlet hole 1541 and transmit the first light R1 in the switch circuit board 15. In the present invention, the light source circuit board 16 is provided with a light source 161 for each light-emitting key 1, that is, each light-emitting key 1 is provided with one light source 161 correspondingly. In practical operation, the light source circuit board 16 corresponding to each light-emitting key 1 may be an independent circuit board, or the light source circuit boards 16 corresponding to all the light-emitting keys 1 on the keyboard may be integrated into a whole layer circuit board, depending on practical requirements. The first light R1 is transmitted along the first straight line L1 avoiding the first hollow portion 152, sequentially passes through the outer frame portion 154 and the first connecting member 1531, and is transmitted from the light incident sidewall 15411 toward the switch portion 151, so as to provide light to the light transmissive key cap 11. Further, after the first light ray R1 is transmitted to the switch portion 151, it can also be transmitted to the second connector 1532 along the second straight line L2 to provide light to a wide area of the light-transmissive key cap 11.
Alternatively, as shown in fig. 12 and 13, fig. 12 is a schematic view illustrating a second structure of the switch circuit board of the light-emitting key of the present invention, fig. 13 is a schematic view illustrating a third structure of the switch circuit board of the light-emitting key of the present invention, and an included angle θ 1 between the first straight line L1 and the second straight line L2 may be 0 degree to 30 degrees. The angle θ 2 between the first line L1 and the normal VL perpendicular to the light-incident sidewall 15411 is 0 to 45 degrees. In addition, the length of the conducting path of the first light R1 emitted from the light source 161 conducted from the light incident side wall 1541 to the switch portion 151 is greater than a quarter of the length of the first edge of the corresponding light-transmitting keycap 11, so as to provide light to a wide area of the light-transmitting keycap 11, the light-transmitting keycap 11 includes the first edge and a second edge perpendicular to the first edge, and the length of the first edge is greater than or equal to the length of the second edge.
Alternatively, as shown in fig. 14, fig. 14 is a diagram illustrating a fourth structure of the switch circuit board of the light-emitting key of the present invention, the switch circuit board 15 further includes an extending part 1533, the extending part 1533 extends from the second side of the switch portion 151 in a direction away from the light-incident side wall 15411 without being connected to the outer frame portion 154, so that the first light R1 is conducted to the switch portion 151 and then conducted to the extending part 1533 along the second straight line L2 to provide light to the light-transmissive keycap 11.
The first light R1 is transmitted to the second connector 1532 or the extension 1533 through the first connector 1531, but since the transmission of the first light R1 on the first connector 1531 and the second connector 1532 or the extension 1533 attenuates energy, the energy of the first light R1 on the second connector 1532 or the extension 1533 is smaller than that on the first connector 1531, so that the switch circuit board 15 of the present embodiment has a plurality of scattering points 17 distributed at intervals on the surface of the second connector 1532 or the extension 1533, and when a portion of the first light R1 contacts any one of the scattering points 17, the portion of the first light R1 can be separated from the second connector 1532 or the extension 1533 and travel upward to the translucent keycap 11, thereby increasing the luminous intensity of the translucent keycap 11 at a distance from the light source 161 and improving the uniformity of the whole luminous effect of the keycap.
Further, the arrangement pitch or the arrangement area of the plurality of scattering points 17 on the surface of the second connector 1532 or the extension member 1533 can be adjusted according to the distance length from the light source 161, that is, the adjacent scattering points of the plurality of scattering points 17 close to the light source 161 are spaced apart from each other by a distance greater than the adjacent scattering points of the plurality of scattering points 17 far from the light source 161, and the arrangement area of the scattering points 17 close to the light source 161 is smaller than the arrangement area of the scattering points 17 far from the light source 161, that is, the scattering points 17 with the denser or larger area are arranged on the surface of the second connector 1532 farther from the light source 161. For example, as shown in FIG. 5, the second link 1532 has a plurality of scattering points 17 thereon, (1) two adjacent scattering points 17 are spaced apart from each other by a first distance D1 closer to the light source 161; (2) at a greater distance from the light source 161, two adjacent scattering points 17 are spaced apart from each other by a second distance D2; the first distance D1 is greater than the second distance D2, that is, the scattering points 17 may not be equidistantly disposed on the surface of the second coupling element 1532, but not limited thereto, for example, as shown in fig. 4, the scattering points 17 may also be equidistantly disposed on the surface of the second coupling element 1532, so as to meet the light emitting effect required by the transparent keycap 11.
Referring to fig. 7-10, fig. 7 is a sectional view of a light-emitting keyboard using a second embodiment of the light-emitting key of the present invention, fig. 8 is an exploded view of components of the second embodiment of the light-emitting key of the present invention, fig. 9 is an assembly view of a switch circuit board and a light source circuit board of the light-emitting key shown in fig. 8, and fig. 10 is a schematic view of a light conduction state of the switch circuit board of the second embodiment of the light-emitting key of the present invention. The main difference between this embodiment and the first embodiment is: the light source circuit board 16 is located below the switch circuit board 15, the light source 161 protrudes upward from the light source circuit board 16, so that the light emitting surface 1611 of the light source 161 enters the light inlet 1541 of the switch circuit board 15, and the frame 14 extends above the light source 161 to shield the light source 161, so that a user cannot see the upper surface of the light source 161, and the amount of light scattered upward by the light source 161 observed by the user is reduced, thereby further increasing the overall aesthetic property of the keyboard.
In addition, the light source circuit board 16 further includes a circuit board supporting portion 163, and the circuit board supporting portion 163 is located between the switch portion 151 and the base plate 12 to eliminate a gap between the base plate 12 and the switch portion 151, thereby firmly supporting the switch portion 151 and ensuring that the switch portion 151 can be smoothly triggered by the light-transmitting key cap 11. As shown in fig. 8, the circuit board supporting portion 163 can also extend between the first connecting member 1531 and the bottom plate 12 and between the second connecting member 1532 and the bottom plate 12, so as to more firmly support the first connecting member 1531 and the second connecting member 1532, and ensure that the transparent key cap 11 can smoothly trigger the switch portion 151.
In addition, with reference to fig. 9, in the present embodiment, the projection of the transparent keycap 11 on the bottom plate 12 forms a transparent keycap projection area 121. The projection of the interlocking member 13 on the bottom plate 12 forms an interlocking member projection area 122. The projection of light incident hole 1541 on bottom plate 12 forms light incident hole projection area 123. The linking member projection area 122 is inside the transparent key cap projection area 121, and the light entrance hole projection area 123 is outside the transparent key cap projection area 121. In this way, there is enough space under the linking member 13 to avoid the linking member 13 interfering with the light source 161 when the transparent key cap 11 moves up and down relative to the bottom plate 12, so as to ensure that the key cap 11 keeps enough up and down movement stroke and reduce the height of the whole keyboard. Of course, the arrangement relationship between the switch circuit board and the light source circuit board can also be used in the light emitting keyboard of the first embodiment.
In summary, each light-emitting key of the light-emitting keyboard of the present invention has a dedicated light source and a switch circuit board. The switch circuit board is provided with a light inlet hole and a connecting piece, wherein the light inlet hole is used for receiving light rays emitted by the light source, and the connecting piece conducts the light rays received by the light inlet hole so as to provide the light rays for the light-transmitting keycaps of the light-emitting keys.
The present invention is capable of other embodiments, and various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention.
