[0044] Common keyboards, such as office keyboards and gaming keyboards, contain various types of keys. Functionally, the key types can be keys with different actuation distances; in terms of appearance, the key types can be round keycaps or square keycaps.

[0045] A key consists of a keycap and a key switch. When a user presses the keycap, the key switch stem moves downwards until it reaches its lowest sliding position. The height difference between the initial position and the lowest position of the key switch stem is the key switch's travel distance.

[0046] Currently, the button press travel of office products, gaming peripherals, and controllers is fixed, and users cannot adjust the press travel according to their own needs. This results in poor versatility. If users want to obtain a satisfactory button trigger travel feel, they need to replace the buttons with buttons of different press travel, which is inconvenient.

[0047] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0048] Figure 1 A schematic diagram of the key structure provided in an embodiment of this application is shown; Figure 2 An exploded view of the buttons provided in an embodiment of this application is shown.

[0049] like Figure 1 , 2 As shown, the key includes a keycap 100 and a key switch 200; the keycap 100 is located on top of the key switch 200. When the user presses the keycap 100, it can cause the key switch 200 to move downward. In one embodiment, the keycap 100 can be round or square.

[0050] Figure 3 A schematic diagram of the structure of a button shaft with adjustable press travel is shown; Figure 4 An exploded view of the adjustable-stroke button shaft is shown; Figure 5 An exploded view of the adjustable-stroke button switch is shown from another perspective.

[0051] like Figure 3 , 4 As shown in Figure 5, an embodiment of this application provides a button shaft with adjustable pressing stroke. The button shaft 200 includes a housing 1, a switch assembly 2, a button shaft core 3, and a stroke adjustment component.

[0052] The housing 1 includes a base 11 and a top cover 12 that cooperate with each other; the housing 1 forms an accommodating space, in which the switch assembly 2, the button shaft 3, and the travel adjustment component are located; in some embodiments of this application, the base 11 and the top cover 12 are interlocked, which facilitates the assembly of the housing 1 and makes the operation simple.

[0053] Figure 4 A schematic diagram of the structure of the switching assembly provided in an embodiment of this application is shown.

[0054] The switch assembly 2 is mounted on the base 11. When the switch assembly 2 is triggered, it outputs a button switch signal. The button shaft 3 is movably mounted inside the housing 1. When the button shaft 3 moves relative to the base 11, it triggers the switch assembly 2.

[0055] In some embodiments of this application, the switch assembly 2 is one of a mechanical switch 21, an optical sensor switch 22, an electromagnetic sensor switch 23, or an inductive sensor switch 24.

[0056] Please see Figure 6 When the switch assembly 2 is a mechanical switch 21, the button shaft 3 moves relative to the base 11 until it triggers the mechanical switch 21 on the base 11, that is, the user presses the button shaft 200 and reaches the trigger stroke of the button shaft 200, at which time the mechanical switch 21 is turned on.

[0057] For example, the mechanical switch 21 may be, but is not limited to, a spring terminal 211 and a fixed terminal 212; when the user presses the button shaft 200 and reaches the trigger stroke of the button shaft 200, the spring terminal 211 is triggered and outputs a button switch signal.

[0058] Please see Figure 7 When the switch assembly 2 is an electromagnetic induction switch 23, the electromagnetic induction switch 23 includes a Hall sensor (not shown) and a magnet that senses the Hall device. The magnet is disposed on the button shaft 3, and the Hall sensor is disposed on the base 11. The button shaft 3 moves relative to the base 11, and after reaching a preset position, the Hall device outputs a trigger command.

[0059] Please see Figure 8 When the switch assembly 2 is an inductive switch 24, the inductive switch 24 includes an electromagnetic induction coil and a sensing rod induced by the electromagnetic induction coil. The sensing rod is disposed on the button shaft core 3, and the electromagnetic induction coil is disposed on the base 11. When the button shaft core 3 moves relative to the base 11 and reaches a preset position, the electromagnetic induction coil outputs a trigger command when it reaches a preset current threshold.

[0060] Please see Figure 9 When the switch assembly 2 is an optical sensor switch 22, the optical sensor switch 22 includes a light emitter (not shown) and a light receiver (not shown). Both the light emitter and the light receiver are mounted on the base 11. When the button shaft core 3 moves relative to the base 11 and reaches a preset position, the light receiver is blocked by the button shaft core 3 from sensing the light source, which reaches a preset intensity range. At this time, the trigger stroke of the button shaft body 200 is reached, and the optical sensor switch 22 is turned on.

[0061] In one implementation, such as Figure 2 , 3As shown, the top cover 12 of the housing 1 has a circular hole 121 through which the key shaft 3 passes, allowing it to slide up and down within the housing 1. When the user presses the keycap 100, it causes the key shaft 3 in the key shaft 200 to move downwards until it reaches the bottommost position where it can slide. The horizontal height of the key shaft 3 when it has not moved downwards is the initial position of the key shaft 3. The height difference between the initial position and the bottommost position of the key shaft 3 is the pressing stroke of the key shaft 200.

[0062] Please see Figure 4-5 The button shaft 200 also includes a reset element 4, having a first end and a second end; the first end contacts the body 51, and the second end contacts the button shaft core 3. The reset element 4 can be a reset spring, which will spring the button shaft core 3 back to its original position after the user presses the button shaft core 3.

[0063] Figure 10 A schematic diagram of the travel stop zone provided in an embodiment of this application is shown. Figure 11 A schematic diagram of the base provided in an embodiment of this application is shown. Figure 12 A schematic diagram of the structure of the movable component provided in an embodiment of this application is shown; Figure 13 This illustration shows a structural schematic diagram of the active component provided in an embodiment of this application from another perspective.

[0064] like Figure 10-13 As shown, the travel adjustment component includes a movable part 5 and multiple travel stop zones 6 with different horizontal heights; the travel stop zones 6 are fixedly installed inside the base 11; the movable part 5 includes a body 51 and a positioning part 52 connected to the body 51; when the body 51 contacts the key shaft 3, the key shaft 3 is located at the bottom of the housing 1; when the body 51 is in motion, the positioning part 52 cooperates with the multiple travel stop zones 6 with different horizontal heights to adjust the horizontal height of the body 51.

[0065] Understandably, the positioning part 52 cooperates with multiple travel stop zones 6 at different horizontal heights to adjust the horizontal height of the movable part 5. By triggering the main body 51, the position of the positioning part 52 can be easily switched, facilitating the adjustment of the bottommost movable position of the button shaft 3 within the housing 1.

[0066] When the key switch 3 moves down from its initial position to its bottom position, the body 51 of the movable part 5 contacts the key switch 3. Therefore, adjusting the horizontal height of the movable part 5 adjusts the lowest movable position of the key switch 3 within the housing 1. The pressing stroke is equal to the lowest movable position of the key switch 3 within the housing 1 minus the initial position of the key switch 3. Therefore, the pressing stroke of the key switch 3 changes. The key switch 200 of this application controls the pressing stroke through the adjustment of the movable part 5, eliminating the need to adjust the pressing stroke via the keycap 100. It is applicable to adjusting the pressing stroke of keys with square or round keycaps 100. The adjustment method is simple and convenient, requiring no key replacement. Users can set it according to their needs, improving the user experience.

[0067] In one implementation, such as Figure 10 As shown, the base 11 has a through hole 111; the main body 51 is disposed through the through hole 111. The main body 51 is rotatably disposed on the base 11. Since the main body 51 passes through the through hole 111, the user can easily adjust the movable part 5, thereby adjusting the bottommost position of the button shaft 3 movable within the housing 1.

[0068] like Figure 10 As shown, the travel stop area 6 is fixedly installed on the inner surface of the base 11 and arranged in a ring. When the main body 51 rotates, the positioning part 52 engages with multiple travel stop areas 6 at different horizontal heights. By rotating the main body 51, the user can rotate the positioning part 52 to a travel stop area 6. Since the travel stop areas 6 are at different horizontal heights, the bottommost movable position of the button shaft 3 within the housing 1 can be adjusted.

[0069] In some embodiments of this application, adjacent travel stop areas 6 are smoothly connected. By rotating the main body 51, the position of the positioning part 52 can be easily switched, facilitating the adjustment of the bottommost movable position of the button shaft 3 within the housing 1.

[0070] In some embodiments of this application, the number of travel stop zones 6 is any one of 2 to 12.

[0071] According to one aspect of the embodiments of this application, a key is provided, including a keycap 100 and a key shaft 200 with adjustable pressing stroke as described above; the keycap 100 is disposed on the top of the key shaft core 3.

[0072] According to one aspect of the embodiments of this application, a keyboard is provided, which includes a key switch 200 with adjustable key travel as described in the above technical solutions, or a key as described in the above technical solutions. The key can be a key for office products, gaming peripherals, and controller products.

[0073] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
