"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0021] In one embodiment, see Figures 1 to 3 As shown, a key provided by the present invention comprises: a key cap guide seat 1, a light-transmitting pressure cap 2, a spring 3, a key cap 4, a signal module 5 and a light-emitting module 6.

[0022] The key cap guide seat 1 has a sliding channel arranged vertically, wherein the key cap guide seat 1 serves as a carrier and is connected to a keyboard.

[0023] The light-transmitting pressing cap 2 is slidably mounted in the sliding channel and extends upwardly out of the key cap guide seat 1. The light-transmitting pressing cap 2 serves as a guide structure and also serves as a guide for the light source 61.

[0024] The spring 3 is installed in the sliding channel, one end of which is connected to the light-transmitting pressing cap 2, and the other end of which is connected to the key cap guide seat 1. The elastic force of the spring 3 pushes the light-transmitting pressing cap 2 to move upward, so that the light-transmitting pressing cap 2 can be reset.

[0025] The key cap 4 is connected to the light-transmitting pressing cap 2 extending out of the key cap guide seat 1 and has a light-transmitting area 41 arranged on the side. The light-transmitting area 41 on the side serves as the position of the key light source 61 .

[0026] The signal module 5 is fixed in the key cap guide 1 and has a signal channel 51 that penetrates the key cap guide 1. The signal channel 51 is used for the passage of signal current and is switched on and off by the sliding of the light-transmitting pressure cap 2. The signal module 5 is electrically connected to the circuit of the keyboard and is used for signal feedback of the key.

[0027] The light emitting module 6 is fixedly mounted in the light-transmitting pressing cap 2, and has a light source 61 and a power circuit 62 that penetrates the key cap guide 1, and the power circuit 62 is electrically connected to the light source 61. The power circuit 62 is electrically connected to the circuit of the keyboard and provides power for the light source 61.

[0028] Specifically, the present invention changes the irradiation height of the light source 61 by arranging the light source 61 in the light-transmitting pressure cap 2, avoids direct exposure of the light source 61 to the human eye, solves the current defect of direct light leakage from the key gaps of the light source 61, and improves the comfort of keyboard use at night.

[0029] In an alternative example, see Figures 1 to 5 As shown, in order to facilitate the disassembly and assembly of the keys, the keycap guide seat 1 includes a lower shell 11 and an upper shell 12 that are mutually engaged, and the sliding channel includes two guide bars 111 arranged in the lower shell 11, and the guide bars 111 are provided with vertical slide grooves 112 arranged vertically, and the light-transmitting pressure cap 2 is inserted into the vertical slide grooves 112 by sliding, and the top of the upper shell 12 is provided with a vertical through groove 121 for the light-transmitting pressure cap 2 to pass through. Among them, the vertical slide groove 112 runs through the top of the guide bar 111; the lower shell 11 and the upper shell 12 are manufactured by injection molding; the light-transmitting pressure cap 2 is provided with a side slider, and the side slider is slidably inserted into the vertical slide groove 112.

[0030] Specifically, in this example, the side wall of the lower shell 11 is provided with a snap-on block 113, and the side wall of the upper shell 12 is provided with a snap-on ring 122 matching the snap-on block 113. During the disassembly and assembly of the keys, the operator presses the upper shell 12 to press the snap-on ring 122 onto the snap-on block 113, thereby fixing the upper shell 12, thereby realizing rapid disassembly and assembly of the keys and improving the disassembly and assembly efficiency of the keycap guide 1.

Among them, a snap-in groove is opened on the outer wall of the plug-in part 21, and an extension block matching the snap-in groove is arranged on the plug-in groove 42. When the extension block is plugged into the snap-in groove, a certain resistance can be generated to limit the relative movement of the key cap 4 and the light-transmitting pressure cap 2. When the key cap 4 needs to be pulled out, the elasticity of the plastic itself can be used to deform, thereby pulling out the key cap 4.

[0032] Specifically, during the disassembly and assembly of the key cap 4 and the light-transmitting pressure cap 2 in this example, the operator aligns the plug-in slot 42 with the position of the plug-in portion 21 and presses downward to insert the plug-in portion 21 into the plug-in slot 42, so that the key cap 4 and the light-transmitting pressure cap 2 are fixed to each other. At the same time, during the installation of the spring 3, the spring 3 is first fitted onto the outer wall of the vertical guide ring 114, and then the vertical guide column 22 is inserted into the spring 3, so as to facilitate the quick disassembly and assembly of the key.

[0033] In an alternative example, see Figures 1 to 7 As shown, in order to facilitate the assembly of the key, the light-emitting module 6 includes a transparent connector 63 inserted and fixed in the light-transmitting pressure cap 2, a light-emitting circuit board 64 is fixed on the transparent connector 63, a light source 61 is fixed on the light-emitting circuit board 64, the light-emitting circuit board 64 is fixedly connected to the transparent connector 63, two groups of conductive members 1 65 for electrical connection are arranged in the vertical guide ring 114, the conductive members 1 65 are arranged along the axial direction of the vertical guide ring 114, two groups of conductive members 2 66 for electrical connection are arranged in the vertical guide column 22, the conductive members 2 66 are arranged along the axial direction of the vertical guide column 22, an illumination circuit 641 is arranged in the light-emitting circuit board 64, one end of a group of conductive members 2 66 is electrically connected to a group of conductive members 1 65 by sliding, and the other end of a group of conductive members 2 66 is electrically connected to an illumination circuit 641 by fixing, and the two groups of conductive members 1 65, conductive members 2 66 and the illumination circuit 641 are combined to form a power supply circuit 62. Among them, a mounting groove 23 is provided at the bottom of the light-transmitting pressure cap 2, and a transparent connecting piece 63 is inserted into the mounting groove 23. A through hole that penetrates vertically is opened on the transparent connecting piece 63, and the vertical guide column 22 passes through the through hole; the light-emitting circuit board 64 can adopt a flexible circuit board or a soft-hard combination circuit board, and the light-emitting circuit board 64 is fixed on the transparent connecting piece 63 by means of adhesive or the like; the light source 61 can adopt LED lamp beads, which are fixed on the light-emitting circuit board 64 by welding; the conductive piece 1 65 and the conductive piece 2 66 are both made of conductive materials, such as copper sheets or copper alloys; the electrical contacts are made of conductive materials, such as copper or copper alloys; the conductive piece 1 65 is electrically connected to the external keyboard circuit board for providing current.

[0034] Specifically, in this example, one group of conductive parts 1 65, conductive parts 2 66 and the illumination circuit 641 constitute the positive circuit of the power supply circuit 62, and another group of conductive parts 1 65, conductive parts 2 66 and the illumination circuit 641 constitute the negative circuit of the power supply circuit 62, thereby realizing power supply for the light source 61, and the transparent connecting part 63 adopts a detachable design, which can be quickly disassembled and assembled, thereby facilitating the maintenance of the light-emitting module 6.

[0035] In an alternative example, see Figures 1 to 9As shown, in order to facilitate the assembly of the buttons, the conductive component 1 65 is integrally injection molded with the lower shell 11 through a metal insert process, and the conductive component 2 66 is integrally injection molded with the light-transmitting pressure cap 2 through a metal insert process. The conductive component 1 65 and the conductive component 2 66 are arranged in an arc shape, and an arc-shaped sliding portion 661 is arranged on the outer wall of the conductive component 2 66, and the sliding portion 661 is in conflict with the conductive component 1 65.

[0036] Specifically, in this example, by pre-fixing the conductive part 1 65 and the conductive part 2 66 at set positions in the mold of the lower shell 11 and the light-transmitting pressure cap 2, after the injection molding of the shell and the light-transmitting pressure cap 2 is completed, a part of the power supply circuit 62 is directly provided, which can greatly reduce the assembly time of the keys, improve the production efficiency of the keys, and reduce the production cost of the keys.

The upper hard circuit board 643 has an upper contact 6431, and the upper contact 6431 is in conflict with the second conductive member 66.

[0038] Specifically, this example fixes the light-emitting circuit board 64 through a transparent connection, which facilitates the rapid installation of the light source 61, can significantly reduce the assembly time of the keys, improve the production efficiency of the keys, and reduce the production cost of the keys.

[0039] In an alternative example, see Figures 1 to 11 As shown, the transparent connecting member 63 is provided with a light emitting groove 632 for accommodating the light emitting circuit board 64 on the side facing away from the light transmission area 41, and a light portion groove 633 is provided in the light emitting groove 632, and the light source 61 is inserted into the light portion groove 633.

In addition, the light-emitting groove 632 is opened on the side away from the light-transmitting area 41, so that the light source 61 is irradiated toward the light-transmitting area 41, thereby ensuring the brightness of the light-transmitting area 41.

[0041] In an alternative example, see Figures 1 to 12 As shown, the light emitting module 6 further includes a light guide sheet 67, one end of which is disposed in the insertion slot 42, and the other end of the light guide sheet 67 is attached to the other end of the light-transmitting area 41.

The upper part of the electrical spring sheet 1 52 has an electrical contact head 521 and a pushing part 522 that are displaced by elasticity. The electrical contact head 521 is in conflict with the electrical spring sheet 2 53. The light-transmitting pressure cap 2 is provided with a contact part 25. When the light-transmitting pressure cap 2 moves vertically, the contact part 25 can contact the pushing part 522 to produce deformation, so that the electrical contact head 521 is separated from the electrical spring sheet 2 53. The first electrical spring 52 and the second electrical spring 53 are combined to form two signal channels 51 . The first electrical spring 52 and the second electrical spring 53 are made of metal materials that can conduct electricity, such as copper sheets or alloy springs.

[0045] See also Fig.14 As shown, a keyboard includes any of the above keys. Since the above keys have the above technical effects, a keyboard with the keys should also have corresponding technical effects.

[0046] In general, the present invention changes the irradiation height of the light source 61 by arranging the light source 61 in the light-transmitting pressure cap 2, avoids direct exposure of the light source 61 to the human eye, solves the current defect of direct light leakage from the light source 61 through the key gaps, and improves the comfort of using the keyboard at night. At the same time, by pre-fixing the conductive member 1 65 and the conductive member 2 66 at set positions in the mold of the lower shell 11 and the light-transmitting pressure cap 2, after the injection molding of the shell and the light-transmitting pressure cap 2 is completed, part of the power circuit 62 is directly provided, which can greatly reduce the assembly time of the keys, improve the production efficiency of the keys, and reduce the production cost of the keys.
