Traditional single-travel keys cannot meet the needs of different users and lack versatility. If users want to obtain a satisfactory key travel feel, they need to replace the keys with keys of different travel, which is inconvenient, costly, and difficult to meet the needs of different users. Furthermore, the trigger response speed of traditional single-travel keys cannot be adjusted, resulting in a poor user experience. Summary of the Invention

[0037] The following specific embodiments illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. Although the description of this application is presented in conjunction with preferred embodiments, this does not mean that the features of this application are limited to this embodiment. On the contrary, the purpose of describing the application in conjunction with embodiments is to cover other options or modifications that may be derived based on the claims of this application. To provide a thorough understanding of this application, many specific details will be included in the following description. This application may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of this application, some specific details will be omitted in the description. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
[0038] In the following description, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more. Directional terms such as "upper," "lower," "left," and "right" are defined relative to the indicated orientation of the components in the accompanying drawings. It should be understood that these directional terms are relative concepts used for relative description and clarification, and they may change accordingly depending on the orientation of the components in the accompanying drawings.
[0039] In this application, unless otherwise expressly specified and limited, the term "connection" shall be interpreted broadly, for example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0040] Common keyboards, such as office keyboards and gaming keyboards, contain various types of keys. In terms of appearance, key types can be round keycaps or square keycaps; in terms of function, key types can be keys with different actuation distances and keys with different trigger response speeds.
[0041] A key's structure 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 and lowest positions of the key switch stem is the key switch's pressing travel. The travel of the key switch stem from its initial position relative to the base until it triggers the switch assembly on the base is the key switch's actuation travel. With a constant pressing speed, a shorter actuation travel results in a faster response time; a longer actuation travel results in a slower response time.
[0042] Therefore, the trigger travel of the button switch is not the same as its pressing travel. The button switch moves from its initial position relative to the base until it triggers the switch assembly on the base. At this point, although the switch assembly is triggered and outputs a button switch signal, the button switch continues to move relative to the base before it contacts it. In this case, the pressing travel of the button switch is greater than its trigger travel. Only when the switch assembly is triggered does the button switch move down to its lowest sliding position. At this point, the pressing travel of the button switch equals its trigger travel.
[0043] Current keyboards have fixed key travel distances, preventing users from adjusting them to their needs. Furthermore, the response speed of keys with single-travel actuation is also unadjustable, resulting in a poor user experience.
[0044] 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.
[0045] Figure 1 shows a schematic diagram of the button structure provided in an embodiment of this application; Figure 2 shows an exploded view of the button provided in an embodiment of this application.
[0046] Figures 1 and 2 illustrate a key 100, including a keycap 1001 and a key switch 200; the keycap 1001 is disposed on top of the key switch core 3. When the user presses the keycap 1001, it can cause the key switch core 3 in the key switch 200 to move downward. In one embodiment, the keycap 1001 can be round or square.
[0047] Figure 3 shows a schematic diagram of the adjustable press travel key shaft; Figure 4 shows an exploded view of the adjustable press travel key shaft.
[0048] As shown in Figures 3 and 4, an embodiment of this application provides a button shaft 200 with adjustable pressing stroke. The button shaft 200 includes a housing 1, a switch assembly 2, a button shaft core 3, a stroke adjustment component, and a reset element 7.
[0049] The housing 1 includes a base 11 and a top cover 12 that cooperate with each other. The interior of the housing 1 forms a receiving space in which the switch assembly 2, the button shaft 3, the travel adjustment component, and the reset element 7 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.
[0050] Figure 5 shows a schematic diagram of the switch assembly. The switch assembly 2 is mounted on the base 11. When the switch assembly 2 is triggered, it outputs a switch signal to the button 100.
[0051] The button shaft 3 has a positioning part 31; the button shaft 3 is movably disposed on the housing 1, and triggers the switch assembly 2 when the button shaft 3 moves relative to the base 11; in some embodiments of this application, the switch assembly 2 is one of a mechanical switch 21, an optical induction switch 22, an electromagnetic induction switch 23, and an inductive induction switch 24.
[0052] Please refer to Figure 5. 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, when the user presses the button shaft 200 and reaches the trigger stroke of the button shaft 200, the mechanical switch 21 is turned on.
[0053] 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 switch signal for the button 100.
[0054] Please refer to Figure 6. 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. After the key shaft core 3 moves to a preset position relative to the base 11, due to the blocking effect of the key shaft core 3 on the light signal emitted by the light emitter, the light intensity sensed by the light receiver is lower than its detection threshold. At this time, the trigger stroke of the key shaft body 200 is reached, and the optical sensor switch 22 is turned on.
[0055] Referring to 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 sensor. The magnet is disposed on the button shaft 3, and the Hall sensor is disposed on the base 11. After the button shaft 3 moves to a preset position relative to the base 11, the Hall sensor outputs a trigger command.
[0056] Referring to 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 that senses the electromagnetic induction coil. The sensing rod is mounted on the button shaft 3, and the electromagnetic induction coil is mounted on the base 11. After the button shaft 3 moves to a preset position relative to the base 11, the electromagnetic induction coil outputs a trigger command when it reaches a preset current threshold.
[0057] Referring to Figure 4, in some embodiments of this application, the reset element 7 is disposed between the base 11 and the button shaft 3. The reset element 7 can be a reset spring, which has a first end and a second end. The first end engages with the base 11, and the second end engages with the bottom of the button shaft 3. After the user presses the button shaft 3, the reset spring springs the button shaft 3 back to its original position.
[0058] Please refer to Figure 9. The travel adjustment component of this application embodiment includes multiple travel stop areas 4 with different horizontal heights. The travel stop areas 4 are disposed in the housing 1. The positioning part 31 cooperates with the multiple travel stop areas 4 with different horizontal heights to position the initial travel position of the key shaft core 3 at different horizontal heights so as to adjust the pressing travel of the key shaft body 200.
[0059] Specifically, the switch component 2 in the key switch 200 can be triggered when the key switch core 3 moves relative to the base 11 to a preset position, outputting a switch signal for the key 100. The positioning part 31 of the key switch core 3 cooperates with multiple travel stop areas 4 of different horizontal heights in the travel adjustment component to position the initial travel position of the key switch core 3 at different horizontal heights, thus adjusting the initial travel position of the key switch core 3. When the key switch core 3 moves relative to the base 11, the initial travel position of the key switch core 3 changes, thus changing the pressing travel of the key switch core 3, thereby adjusting the pressing travel of the key switch core 3. Furthermore, when the key switch core 3 moves relative to the base 11, the timing of triggering the switch component 2 also changes due to the change in the initial travel position of the key switch core 3, thereby adjusting the trigger response speed of the key switch 200. The key switch 200 of this application allows for adjustable pressing travel and trigger response speed. The adjustment method is simple and convenient, requiring no replacement of the key 100. Users can set it reasonably according to their own needs, improving the user experience.
[0060] In other words, in this embodiment, the different horizontal heights of the key shaft core 3 can be understood as follows: taking a fixed point on the base 11 (e.g., the lowest point in the axial direction) as a reference position, multiple travel stop areas 4 have different height differences from this fixed point in the pressing direction of the key shaft core 3 or in the axial direction of the key shaft core 3; when the key shaft core 3 is engaged with different travel stop areas 4, the height difference between the initial travel position of the key shaft core 3 (i.e., the position when not pressed) and the fixed point is also different, so that the initial travel position of the key shaft core 3 can be positioned at different horizontal heights, thereby realizing the variable adjustment of the pressing travel of the key shaft core 3. As the pressing travel of the key shaft core 3 changes, the trigger travel also changes accordingly, that is, the trigger response speed of the key shaft body 200 is adjusted.
[0061] The travel stop zone 4 of this application is set inside the housing 1. Through the positioning part 31, it cooperates with multiple travel stop zones 4 at different horizontal heights. The user only needs to adjust the internal structure of the key switch body 200 without adjusting the keycap 1001. It is applicable to the adjustment of the pressing travel of the key 100 with square keycap 1001 or the key 100 with round keycap 1001, so as to realize the adjustment and control of the pressing travel and trigger response speed.
[0062] As shown in Figure 9, the travel stop area 4 is fixedly disposed within the housing 1; the travel adjustment component also includes a movable member 5; when the movable member 5 is in motion, the positioning part 31 cooperates with multiple travel stop areas 4 at different horizontal heights. For example, referring to Figures 5 and 9, the movable member 5 is sleeved on the key shaft 3, cooperating with the key shaft 3 and limiting the movement range of the key shaft 3. The movable member 5 can be driven to move relative to the housing 1, thereby changing its relative position with the housing 1 in the pressing direction or axial direction of the key shaft 3. Through the limiting effect of the movable member 5 on the key shaft 3, the limit position (i.e., the initial travel position) of the key shaft 3 during the upward movement or rebound process can be limited. In other words, the travel range of the key shaft 3 is adjusted by adjusting the position of the movable member 5 within the housing 1.
[0063] Specifically, the travel stop area 4 is fixedly set on the inner surface of the top cover 12. Through the positioning part 31 cooperating with multiple travel stop areas 4 at different horizontal heights, the initial travel position of the key shaft core 3 is positioned at different horizontal heights, thus adjusting the initial position of the key shaft core 3. The advantage of this method is that the initial position of the key shaft core 3 can be adjusted by adjusting the movable part 5.
[0064] In some embodiments of this application, the movable member 5 is a rotating member; the travel stop area 4 is fixedly disposed on the inner surface of the top cover 12 and arranged in a ring. As shown in FIG9, during the rotation of the rotating member, the lower part of the rotating member can cooperate with the travel stop area 4 to position the initial travel position of the key shaft core 3 at different horizontal heights. When the user operates the rotating member to rotate, the rotating member drives the positioning part 31 to cooperate with multiple travel stop areas 4 at different horizontal heights to adjust the initial position of the key shaft core 3.
[0065] Please refer to Figure 10. In some embodiments of this application, the travel stop area 4 is rotatably disposed inside the housing 1; when the travel stop area 4 rotates, the positioning part 31 cooperates with multiple travel stop areas 4 at different horizontal heights.
[0066] Specifically, the travel stop area 4 located inside the housing 1 engages with multiple travel stop areas 4 at different horizontal heights during rotation. The advantage of this method is that the initial position of the key shaft core 3 can be adjusted by adjusting the travel stop area 4.
[0067] Please refer to Figure 11. In some embodiments of this application, the stroke adjustment component further includes a rotating body 6; the rotating body 6 is sleeved on the key shaft core 3; and the stroke stop area 4 is fixedly disposed at the lower end of the rotating body 6.
[0068] Specifically, the rotating body 6 is mounted on the key shaft core 3, and the rotation of the rotating body 6 drives the travel stop area 4 to rotate.
[0069] Referring to Figure 11, in some embodiments of this application, the top of the rotating body 6 is flush with the top of the key shaft 3, or in other words, the end of the rotating body 6 away from the housing 1 is flush with the end of the key shaft 3 away from the housing 1. The flush alignment of the top of the rotating body 6 with the top of the key shaft 3 allows the user to press the rotating body 6 individually and then rotate it, thereby rotating the travel stop area 4 and adjusting the initial position of the key shaft 3. The advantage of this method is that when structural interference occurs between the travel stop area 4 and the housing 1, the user can press the rotating body 6 individually, avoiding interference between the travel stop area 4 and the housing 1 and thus preventing the rotation of the travel stop area 4 from being affected.
[0070] Please refer to Figures 12 and 13. In some embodiments of this application, the stroke adjustment component further includes a rotating body 6; the rotating body 6 is disposed on the top cover 12.
[0071] Specifically, the rotating body 6 is mounted on the top cover 12. The user can operate the rotating body 6 to rotate. During the rotation, the positioning part 31 cooperates with multiple travel stop areas 4 at different horizontal heights to adjust the initial position of the button shaft core 3.
[0072] Please refer to Figures 14 and 15. In some embodiments of this application, the travel stop area 4 is slidably disposed in the housing 1; the positioning part 31 cooperates with a plurality of travel stop areas 4 at different horizontal heights; when the travel stop area 4 slides, the positioning part 31 cooperates with a plurality of travel stop areas 4 at different horizontal heights.
[0073] Specifically, the user operates the travel stop area 4 to slide, and the positioning part 31 cooperates with multiple travel stop areas 4 at different horizontal heights to adjust the initial position of the button shaft core 3.
[0074] Please refer to Figure 9. In some embodiments of this application, adjacent travel stop areas 4 are smoothly connected. For example, adjacent travel stop areas 4 are connected by an inclined surface 41. The travel stop areas 4 can be rotated or slid to easily switch the position of the positioning part 31, which facilitates the adjustment of the initial position of the key shaft core 3.
[0075] In some embodiments of this application, multiple travel stop zones 4 form a stepped structure.
[0076] In some embodiments of this application, the pressing stroke of the key shaft 200 ranges from 0.1 to 10 mm.
[0077] In some embodiments of this application, the number of travel stop zones 4 is any one of 2 to 12.
[0078] This application embodiment also provides a button 100, which includes a keycap 1001 and a button shaft 200 with adjustable pressing stroke as described above; the keycap 1001 is disposed on the top of the button shaft core 3. The button 100 can be a keyboard button, a gamepad button, or an arcade game button.
[0079] This application also provides a keyboard, which includes a key switch 200 with adjustable press travel as described in the above technical solutions, or a key 100 as described in the above technical solutions. The above descriptions are merely specific embodiments 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.
