Description

Technical Field

[0001] The present invention relates to an input device, and particularly to a keyboard device. Background Art

[0002] The keyboard is one of the very common input devices for current electronic devices. For example, computer products (such as notebook computers, desktop computers or tablet computers) often contacted in daily life, or large control devices or processing devices in industry, mostly use keyboards for operation or text input.

[0003] Currently, some keyboards on the market use a backlight module as a light source to improve the visibility of the keyboard in low-light environments, and can also provide users with the option to choose different backlight color combinations according to their own preferences. Summary of the Invention

[0004] In view of the above, in one embodiment, a keyboard device is provided, including a circuit board, a key assembly and a lighting module. The circuit board has a top surface, and the top surface has an assembly area. A first conductive portion and a second conductive portion are provided in the assembly area. The key assembly is disposed on the assembly area of the circuit board. The key assembly includes a keycap and a reset member. The reset member is disposed between the keycap and the circuit board to make the keycap in a height position. The lighting module is disposed on the keycap. The lighting module includes a lighting element, a first conductive contact point and a second conductive contact point. The lighting element is electrically connected to the first conductive contact point and the second conductive contact point. Wherein, when the keycap is in the height position, the first conductive contact point and the second conductive contact point are respectively disconnected from the first conductive portion and the second conductive portion; when the keycap descends from the height position towards the circuit board to a trigger position, the first conductive contact point and the second conductive contact point respectively directly or indirectly conduct the first conductive portion and the second conductive portion, so that the lighting element emits light.

[0005] In summary, according to the keyboard device of the embodiment of the present invention, when the keycap is not pressed by the user, the lighting element of the lighting module on the keycap does not emit light. When the keycap is pressed by the user and descends to the trigger position, the lighting element on the keycap emits light. Therefore, the user can clearly know that the keycap has been actually pressed through the light, and the brightness change of the lighting element can also provide a richer interactive effect and usage experience.

[0056] It should be noted that in the description of each embodiment, the so-called "first", "second", "third" are used to describe different elements, and these elements are not limited by such predicates. In addition, for the convenience and clarity of description, the thickness or size of each element in the drawings is represented in an exaggerated, omitted or schematic manner for the understanding and reading of those skilled in the art, and the size of each element is not its actual size, and it is not used to limit the implementable conditions of the present invention, so it does not have technical substantial significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the efficacy and purpose that the present invention can achieve, should still fall within the scope covered by the technical content disclosed in the present invention. The same reference numerals will be used to represent the same or similar elements in all the drawings.

[0057] Figure 1 is a partial perspective view of an embodiment of the keyboard device of the present invention. Figure 2 is a partial exploded perspective view of the first embodiment of the keyboard device of the present invention. Figure 3 is a partial cross-sectional view of the first embodiment of the keyboard device of the present invention. As Figure 1 and Figure 2 shown, the keyboard device 1 includes a circuit board 10, at least one key assembly 20 and a lighting module 30. In this embodiment, the number of key assemblies 20 is multiple and arranged on the circuit board 10. In some embodiments, the keyboard device 1 can be applied to various electronic products (such as input devices of desktop computers, notebook computers or other electronic devices) for users to operate to generate corresponding signals.

[0058] As Figures 1 to 3 shown, the circuit board 10 can be disposed on a substrate 17, where the substrate 17 can be a rigid board made of metal (such as iron, aluminum or alloy, etc.) or plastic material. The circuit board 10 has a top surface 15, and the top surface 15 has at least one assembly area 16 (such as Figure 2 shown square area), that is to say, the assembly area 16 is a partial area of the top surface 15 of the circuit board 10. In this embodiment, the number of assembly areas 16 is multiple to respectively correspond to the assembly of multiple key assemblies 20.

[0059] In some embodiments, the above-mentioned circuit board 10 can be various circuit boards such as a membrane circuit board, a printed circuit board (PCB), a flexible printed circuit board (FPCB) or a rigid-flex PCB.

[0060] As Figure 2 and Figure 3As shown, taking one of the assembly areas 16 as an example, the first conductive part 11 and the second conductive part 12 are provided in the assembly area 16, and the first conductive part 11 and the second conductive part 12 are arranged at intervals from each other. The first conductive part 11 and the second conductive part 12 can be conductive layers made of conductive materials. For example, the conductive materials can be gold, silver, copper, alloys or conductive carbon, and the conductive materials can be printed on the top surface 15 of the circuit board 10 through printing technology to form the first conductive part 11 and the second conductive part 12, and the first conductive part 11 and the second conductive part 12 can be respectively connected to a power supply (not shown here) through the circuits 101, 102.

[0061] As Figure 2 shown, each key assembly 20 is arranged on one of the assembly areas 16 of the circuit board 10. Each key assembly 20 includes a keycap 21, a reset member 25 and a linkage member 27. The reset member 25 is arranged between the keycap 21 and the circuit board 10, so that the keycap 21 is located at a height position (such as Figure 3 the position shown). For example, the reset member 25 can be an elastic body such as a rubber dome, a metal dome, a spring or a spring piece. When the keycap 21 is pressed by a user, the keycap 21 can descend towards the circuit board 10 to a trigger position (such as Figure 3 the position shown), so that the reset member 25 is pressed to accumulate elastic force. When the keycap 21 is released, the accumulated elastic force of the reset member 25 can drive the keycap 21 to rise and return to the above-mentioned height position. Figure 4 As shown, the linkage member 27 is movably connected between the keycap 21 and the substrate 17. The linkage member 27 can be a scissor-type connecting member (such as

[0062] shown) or other multi-link structures. When the keycap 21 rises or descends, the linkage member 27 can act synchronously to guide the keycap 21 to lift relative to the circuit board 10 and the substrate 17. Figure 2 shown, and Figure 3 As Figure 2 shown, and Figure 3 When the keycap 21 rises or descends, the linkage member 27 can act synchronously to guide the keycap 21 to lift relative to the circuit board 10 and the substrate 17.

[0063] As Figure 2 shown, and Figure 3As shown, the lighting module 30 is disposed on the keycap 21. The lighting module 30 includes a lighting element 35A, a first conductive contact 31, and a second conductive contact 32. The lighting element 35A is electrically connected to the first conductive contact 31 and the second conductive contact 32. In this embodiment, the lighting module 30 is disposed on the side of the keycap 21 facing the circuit board 10. The first conductive contact 31 and the second conductive contact 32 are spaced apart from each other. The first conductive contact 31 and the second conductive contact 32 may be conductive layers made of a conductive material. For example, the conductive material may be gold, silver, copper, an alloy, or conductive carbon. In addition, one of the first conductive contact 31 and the second conductive contact 32 is a positive electrode contact, and the other is a negative electrode contact. The position of the first conductive contact 31 corresponds to the position of the first conductive portion 11, and the position of the second conductive contact 32 corresponds to the position of the second conductive portion 12. The lighting element 35A can be connected to the first conductive contact 31 and the second conductive contact 32 through a plurality of conductive lines 351, 352 respectively.

[0064] As Figure 2 shown, in this embodiment, the lighting module 30 includes an insulating layer 36. The insulating layer 36 is fixed on the side of the keycap 21 facing the circuit board 10. For example, the insulating layer 36 may be a flexible insulating film such as a polyester film or a polyimide film. The insulating layer 36 can be fixed to the keycap 21 by means of hot pressing or adhesion, etc., but the setting method is not limited thereto. The above-mentioned lighting element 35A, the first conductive contact 31, and the second conductive contact 32 are disposed on the insulating layer 36. In other embodiments, the first conductive contact 31 and the second conductive contact 32 may also be directly disposed on the surface of the keycap 21, and the component of the insulating layer 36 can be omitted. For example, a metal (such as copper or silver) can be coated on the surface of the keycap 21 by electroplating, and then the circuit and contacts can be formed by means of development and etching processes.

[0065] As Figure 3 shown, when the keycap 21 is not pressed by the user and is in the above-mentioned height position, the first conductive contact 31 does not contact the first conductive portion 11 and is disconnected from each other, and the second conductive contact 32 does not contact the second conductive portion 12 and is disconnected from each other, so that the current of the power supply connected to the circuit board 10 cannot flow through the lighting element 35A, thereby making the lighting element 35A not emit light. In addition, during the process that the keycap 21 is pressed by the user and descends from the above-mentioned height position towards the circuit board 10, the first conductive contact 31 will approach the first conductive portion 11, and the second conductive contact 32 will approach the second conductive portion 12. Then, please refer to Figure 2 and Figure 4As shown, when the keycap 21 descends to the triggering position, the first conductive contact point 31 and the first conductive part 11 can be in direct or indirect contact to conduct electricity, and the second conductive contact point 32 and the second conductive part 12 can be in direct or indirect contact to conduct electricity, causing the circuit board 10 to connect the power supply lines 101, 102 and the conductive lines 351, 352 connected to the light-emitting element 35A to conduct electricity with each other to form a loop, so that the light-emitting element 35A emits bright light.

[0066] In summary, in the keyboard device 1 of the embodiment of the present invention, when the keycap 21 is not pressed by the user, the light-emitting element 35A of the light-emitting module 30 on the keycap 21 does not emit bright light. When the keycap 21 is pressed by the user and descends to the triggering position, the light-emitting element 35A on the keycap 21 emits bright light. Therefore, the user can clearly know that the keycap has been actually pressed through the bright light, and the brightness change of the light-emitting element 35A can also provide a richer interactive effect and user experience.

[0067] The conduction methods of the above-mentioned first conductive contact point 31 and the first conductive part 11 and the conduction methods of the second conductive contact point 32 and the second conductive part 12 can have the following multiple different implementation manners, which are respectively described in conjunction with the accompanying drawings as follows.

[0068] As Figure 3 and Figure 4 shown, in the first embodiment, the keycap 21 includes a cap 22 and a brim 23. The cap 22 has an inner surface 221. The brim 23 surrounds the periphery of the inner surface 221 and extends toward the circuit board 10. The brim 23 has a bottom surface 231 facing the circuit board 10. The first conductive contact point 31 and the second conductive contact point 32 are respectively arranged on two opposite sides of the bottom surface 231, so that the first conductive contact point 31 and the second conductive contact point 32 are closer to the circuit board 10 relative to the inner surface 221 of the cap 22. In addition, as Figure 4 shown, when the keycap 21 is pressed by the user and descends to the triggering position, the first conductive contact point 31 and the first conductive part 11 are in direct contact to conduct electricity, and the second conductive contact point 32 and the second conductive part 12 are also in direct contact to conduct electricity.

[0069] Figure 5 is a partial cross-sectional view of the second embodiment of the keyboard device of the present invention, Figure 6 is Figure 5 the pressing schematic diagram. As Figure 5 and Figure 6 shown, the difference between this embodiment and the above-mentioned first embodiment is that in the second embodiment, the second conductive contact point 32 is changed to be arranged near the center of the inner surface 221 of the cap 22, so that the first conductive contact point 31 is closer to the circuit board 10 than the second conductive contact point 32, and as Figure 6As shown, when the keycap 21 is pressed by the user and descends to the trigger position, the first conductive contact 31 is directly in contact with the first conductive portion 11 and is conductive, and the second conductive contact 32 is indirectly in contact with the second conductive portion 12 via a conductor 26 and is conductive.

[0070] like Figure 5 and Figure 6 As shown, in this embodiment, the conductor 26 is combined with the reset member 25 and is located between the second conductive contact 32 and the second conductive portion 12, wherein the conductor 26 can be a column made of a conductive material, for example, the conductive material can be gold, silver, copper, alloy or conductive carbon. In addition, the conductor 26 can be combined with the reset member 25 by embedding, bonding or injection molding. For example, the reset member 25 and the conductor 26 can be integrally formed by insert molding or double injection molding.

[0071] For example Figure 5 and Figure 6 As shown, in this embodiment, the reset member 25 is a rubber dome, and the reset member 25 has a top 251 and a bottom 255, and the top 251 has a first groove 252, and the bottom 255 has a second groove 256. The top 251 of the reset member 25 abuts against the key cap 21, and the bottom 255 abuts against the circuit board 10. The conductor 26 is combined with the inside of the reset member 25, and the second conductive contact 32 and the top 261 of the conductor 26 are located in the first groove 252, and the bottom 262 of the conductor 26 is located in the second groove 256. When the key cap 21 is not pressed by the user and is at a high position (such as Figure 5 The top end 261 of the conductor 26 is kept away from the second conductive contact 32 and does not contact each other, and the bottom end 262 of the conductor 26 is kept away from the second conductive portion 12 and does not contact each other. When the key cap 21 is pressed by the user and descends to the trigger position (as shown in FIG. Figure 6 As shown in the position, the reset member 25 will collapse under pressure, causing the top end 261 of the conductor 26 to contact the second conductive contact 32 and the bottom end 262 of the conductor 26 to contact the second conductive portion 12, so that the second conductive contact 32 can indirectly contact the second conductive portion 12 via the conductor 26 and be conductive.

[0072] Figure 7 is a partial cross-sectional view of a third embodiment of a keyboard device of the present invention, Figure 8 for Figure 7 Schematic diagram of pressing. Figure 7 and Figure 8As shown, the difference between this embodiment and the above-mentioned first and second embodiments lies in that, in the third embodiment, the first conductive contact point 31 and the second conductive contact point 32 are both disposed near the center on the inner surface 221 of the cap 22. When the keycap 21 is at the height position without being pressed by the user (as shown in Figure 7 the position shown), the first conductor 26A does not contact the first conductive contact point 31 and the first conductive portion 11, and the second conductor 26B does not contact the second conductive contact point 32 and the second conductive portion 12. When the keycap 21 is pressed by the user and descends to the trigger position (as shown in Figure 8 the position shown), the first conductor 26A contacts the first conductive contact point 31 and the first conductive portion 11, and the second conductor 26B contacts the second conductive contact point 32 and the second conductive portion 12. That is to say, the first conductive contact point 31 is indirectly connected to the first conductive portion 11 through the first conductor 26A to be turned on, and the second conductive contact point 32 is indirectly connected to the second conductive portion 12 through the second conductor 26B to be turned on.

[0073] Thereby, by centrally disposing the first conductive contact point 31 and the second conductive contact point 32 near the center on the inner surface 221 of the cap 22, it is possible to prevent the first conductive contact point 31 and the second conductive contact point 32 from being too far apart, which is beneficial to ensuring that the first conductive contact point 31 and the second conductive contact point 32 respectively and simultaneously contact the first conductive portion 11 and the second conductive portion 12. In addition, the light-emitting element 35A of the light-emitting module 30 and the insulating layer 36 can also be disposed only near the center on the inner surface 221 of the keycap 21, so that the insulating layer 36 does not need to extend to the bottom surface 231 of the cap brim 23 or the periphery of the inner surface 221, thereby reducing the manufacturing difficulty and significantly reducing the material cost.

[0074] In addition, the conduction mode between the first conductive contact point 31, the first conductor 26A and the first conductive portion 11 in the above-mentioned third embodiment and the conduction mode between the second conductive contact point 32, the second conductor 26B and the second conductive portion 12 can be the same as the conduction mode between the second conductive contact point 32, the conductor 26 and the second conductive portion 12 in the above-mentioned second embodiment, and will not be repeated here.

[0075] Again, such as Figure 7 and Figure 8As shown, in this embodiment, the first conductor 26A and the second conductor 26 are both coupled to the reset member 25. The first conductor 26A is located between the first conductive contact 31 and the first conductive portion 11, and the second conductor 26B is located between the second conductive contact 32 and the second conductive portion 12. Among them, the first conductor 26A and the second conductor 26B can be columns made of conductive materials. For example, the conductive materials can be gold, silver, copper, alloys, or conductive carbon. In addition, the first conductor 26A and the second conductor 26B can be coupled to the reset member 25 by means such as fitting, adhesion, or injection molding. For example, the first conductor 26A, the second conductor 26B, and the reset member 25 can be integrally formed by means such as insert molding or double injection molding.

[0076] In the above embodiments, when the keycap 21 is pressed by a user and descends from the height position towards the circuit board 10 to the trigger position, the circuit board 10 can correspondingly generate a key trigger signal. The key trigger signal can be used to cause the corresponding operating system to display the corresponding characters or execute specific shortcut key functions, etc. Among them, the above key trigger signal can be generated when the first conductive portion 11 conducts the first conductive contact 31 or when the second conductive portion 12 conducts the second conductive contact 32. Alternatively, the circuit board 10 can be additionally provided with a switch, and the switch is used to be triggered to generate a key trigger signal when the keycap 21 descends to the trigger position. This is separately described with reference to the accompanying drawings as follows.

[0077] For example, the first conductive portion 11 or the second conductive portion 12 in the above embodiments can be a finger-shaped electrode, as Figure 9 shown. Taking the first conductive portion 11 as an example, the first conductive portion 11 in the above embodiments can have a first trigger line 111 and a second trigger line 112 that are spaced apart from each other. As Figure 3 、 5 and 7 show, when the keycap 21 is not pressed by a user and is in the height position, since the first conductive contact 31 does not contact the first conductive portion 11, the first trigger line 111 and the second trigger line 112 of the first conductive portion 11 are disconnected from each other and no key trigger signal is generated. As Figure 4 、 6 and 8 show, when the keycap 21 is pressed by a user and descends from the height position towards the circuit board 10 to the trigger position, the first conductive contact 31 and the first conductive portion 11 can be directly or indirectly contacted, so that the first trigger line 111 and the second trigger line 112 of the first conductive portion 11 are conducted with each other to generate the above key trigger signal, achieving that the first conductive contact 31 and the first conductive portion 11 can be simultaneously used for triggering the light-emitting member 35A and triggering the key, without additionally providing a switch.

[0078] Alternatively, a trigger switch may be additionally provided on the circuit board 10 of each of the above embodiments to generate a key trigger signal via the trigger switch. For example, the trigger switch may be a pressure sensing switch, an optical sensing switch, a membrane switch, or a finger electrode switch, etc. For example, as Figure 3 and Figure 4 shown, a trigger switch 14 may be provided at the position of the circuit board 10 corresponding to the reset member 25. The trigger switch 14 may be, for example, a pressure sensing switch. When the keycap 21 is pressed and descends to the trigger position (as Figure 4 shown), the reset member 25 can press against the trigger switch 14 to generate a key trigger signal. Or, as Figure 7 and Figure 8 shown, a trigger switch 14A is provided at the position of the circuit board 10 corresponding to the reset member 25. The trigger switch 14A may be, for example, a finger electrode switch (as Figure 9 shown in the switch type). A third conductor 26C is also incorporated in the reset member 25. Here, the third conductor 26C may be a column made of a conductive material. When the keycap 21 is pressed and descends to the trigger position (as Figure 8 shown), the third conductor 26C can contact the trigger switch 14A to generate a key trigger signal. Or, as Figure 10 and Figure 11 shown, it is a partial cross-sectional view and a pressing schematic diagram of the fourth embodiment of the keyboard device of the present invention. In this embodiment, a trigger switch 14B is provided at the position of the circuit board 10 corresponding to the reset member 25. The trigger switch 14B may be, for example, a membrane switch. When the keycap 21 is pressed and descends to the trigger position (as Figure 11 shown), the reset member 25 can press against the trigger switch 14B to make the two contacts of the trigger switch 14B contact and conduct to generate a key trigger signal.

[0079] Figure 12 is a partial cross-sectional view of the fifth embodiment of the keyboard device of the present invention. As Figure 12 shown, the difference between this embodiment and the above first embodiment is that the light emitting module 30 of this embodiment further includes another light emitting member 35B and a third conductive contact 33, and a third conductive portion 13 is also provided in the assembly area 16 of the circuit board 10. The light emitting member 35A is electrically connected to the first conductive contact 31 and the second conductive contact 32, and the light emitting member 35B is electrically connected to the first conductive contact 31 and the third conductive contact 33. That is to say, the two light emitting members 35A and 35B are commonly connected to the first conductive contact 31. Among them, the first conductive contact 31 may be a negative electrode contact, and the second conductive contact 32 and the third conductive contact 33 are positive electrode contacts.

[0080] Thus, as Figure 12As shown, when the keycap 21 is at the height position without being pressed by the user, the first conductive contact 31, the second conductive contact 32, and the third conductive contact 33 are respectively disconnected from the first conductive portion 11, the second conductive portion 12, and the third conductive portion 13, so that both the two light-emitting elements 35A and 35B do not emit light. When the keycap 21 is pressed by the user and descends from the height position to the trigger position toward the circuit board 10, the first conductive contact 31, the second conductive contact 32, and the third conductive contact 33 are respectively in direct or indirect contact with the first conductive portion 11, the second conductive portion 12, and the third conductive portion 13 to conduct, so that the two light-emitting elements 35A and 35B emit light simultaneously. Therefore, multiple light-emitting elements 35A and 35B in the embodiments of the present invention can share the same contact (i.e., the first conductive contact 31), achieving the advantages of reducing the number of contacts and effectively reducing the manufacturing cost.

[0081] Although the technical content of the present invention has been disclosed above in preferred embodiments, it is not intended to limit the present invention. Any person skilled in this art, without departing from the spirit of the present invention, makes some modifications and refinements, which should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the appended claims.
