[0006] In some embodiments of this application, the stroke adjustment member is threadedly connected to the top cover; the top of the positioning part contacts the bottom of the stroke adjustment member.

[0008] In some embodiments of this application, a limiting member is also included; the limiting member is used to axially limit the stroke adjustment member.

[0009] In some embodiments of this application, the limiting member includes a recess and a convex portion; the recess is disposed in the circumferential direction of the stroke adjusting member; the convex portion is disposed on the top cover; the recess and the convex portion cooperate to limit the axial movement of the stroke adjusting member.

[0010] In some embodiments of this application, a locking member is also included; the locking member is disposed on the top cover; the locking member cooperates with the stroke adjusting member to limit the rotation of the stroke adjusting member.

[0038] 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.

[0039] 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.

[0040] 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.

[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] In existing technology, the actuation distance of key switches is usually fixed and cannot be adjusted according to user habits and needs. This may affect the user experience for some users with special requirements for key operation. For example, gamers may need a shorter actuation distance for quick response, while ordinary office users may prefer a longer actuation distance for a more comfortable feel.

[0043] 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.

[0044] 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.

[0045] 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 core 3. When the user presses the keycap 100, it can push the key switch 200 downward. In one embodiment, the keycap 100 can be round or square.

[0046] Figure 3 A schematic diagram of the key switch body is shown; Figure 4 , 5 An exploded view of the key switch body is shown; Figure 6 A cross-sectional view of the key switch shaft is shown.

[0047] like Figure 3-6 As shown in the figure, a button shaft 200 according to an embodiment of this application includes a housing 1, a switch assembly 2, a button shaft core 3, a travel adjustment component 4, and a reset element 5.

[0048] The housing 1 includes a base 11 and a top cover 12 that cooperate with each other. The base 11 and the top cover 12 are connected by a suitable means, such as a snap-fit ​​connection or a threaded connection, to form a relatively enclosed space for accommodating other components; in this embodiment, the switch assembly 2, the button shaft 3, the travel adjustment component 4, and the reset element 5 are located within this enclosed space.

[0049] like Figure 4-6 As shown, a reset element 5 is disposed between the base 11 and the button shaft 3. After being pressed from its initial position, the button shaft 3 moves downwards. After moving to a certain height, the reset element 5 causes the button shaft 3 to spring back to its initial position. For example, the reset element 5 can be a spring. The spring 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 33. After the user presses the button shaft 3, the spring springs the button shaft 3 back to its original position.

[0050] like Figure 4-6 As shown, switch component 2 is mounted on base 11. When switch component 2 is triggered, it outputs a button switch signal.

[0051] The button shaft 3 has a positioning part 31; the button shaft 3 is movably disposed in the housing 1, and triggers the switch assembly 2 when the button shaft 3 moves relative to the base 11.

[0052] In some embodiments of this application, the switch assembly 2 is one of a mechanical switch, an optical sensor switch, an electromagnetic sensor switch, or an inductive sensor switch.

[0053] In one embodiment, when the switch assembly 2 is a mechanical switch, the button shaft 3 moves relative to the base 11 until it triggers the mechanical switch on the base 11. At this time, the user presses the button shaft 200 and reaches the trigger stroke of the button shaft 200, at which time the mechanical switch is turned on.

[0054] In one embodiment, when the switch assembly 2 is an optical sensor switch, the optical sensor switch outputs a signal by blocking or reflecting light.

[0055] The switch assembly 2 in this embodiment can also be an electromagnetic induction switch or an inductive induction switch; this embodiment does not limit it in this way.

[0056] In this embodiment, the travel adjustment member 4 is connected to the top cover 12 and is rotatably sleeved on the key shaft core 3. When the travel adjustment member 4 rotates, the positioning part 31 cooperates with the travel adjustment member 4 to position the key shaft core 3 to a preset horizontal height range, so as to adjust the pressing stroke of the key shaft body 200.

[0057] Specifically, the button shaft core 3 has a positioning part 31. When the positioning part 31 is at different horizontal heights, the button shaft core 3 is at different horizontal heights. The positioning part 31 cooperates with the travel adjustment member 4. When the travel adjustment member 4 rotates, the positioning part 31 will be at different horizontal heights as the travel adjustment member 4 rotates.

[0058] For example, the initial travel range of the button shaft core 3 is preset to 0-1.5mm, meaning that the pressing travel of the button shaft body 200 can be freely adjusted within the range of 0-1.5mm. The initial travel range of the button shaft core 3 can also be other ranges, and this embodiment does not limit this.

[0059] like Figure 6 As shown, in some embodiments of this application, the stroke adjustment member 4 is connected to the top cover 12 by a thread 41; the top of the positioning part 31 contacts the bottom of the stroke adjustment member 4.

[0060] Specifically, the mating surfaces of the travel adjustment component 4 and the top cover 12 are both provided with threads 41. Since the travel adjustment component 4 is rotatably fitted onto the key shaft core 3, it can be adjusted up and down by the user. The top of the positioning part 31 contacts the bottom of the travel adjustment component 4. When the travel adjustment component 4 rotates, it pushes the positioning part 31, causing the key shaft core 3 to move vertically, thereby positioning the key shaft core 3 within a preset horizontal height range, thus achieving adjustment of the pressing stroke. Therefore, the pressing stroke of the key shaft core 3 can be freely adjusted within a preset range, and the adjustment method is convenient.

[0061] Because the initial travel position of the key shaft core 3 changes, the triggering time of the switch assembly 2 also changes, thereby adjusting the triggering response speed of the key shaft 200. The key shaft 200 of this application allows for flexible adjustment and control of both the pressing travel and the triggering response speed, with a simple and convenient adjustment method.

[0062] Figure 7 A schematic diagram showing the connection between the stroke adjuster and the top cover clearance fit is shown; Figure 8 A cross-sectional view showing the clearance fit between the stroke adjuster and the top cover is shown.

[0063] The stroke adjustment component 4 is clearance-fitted with the top cover 12; the bottom of the stroke adjustment component 4 is provided with a contact part 42, and the contact part 42 has an inclined surface 421; when the stroke adjustment component 4 rotates, the inclined surface 421 engages with the positioning part 31.

[0064] Specifically, when the travel adjustment member 4 rotates, the inclined surface 421 on the contact part 42 pushes the positioning part 31, causing the key shaft core 3 to move in the vertical direction, thereby adjusting the pressing stroke. For example, when the higher end of the inclined surface 421 contacts the positioning part 31, the key shaft core 3 is pressed down to a lower position, and the pressing stroke becomes shorter; when the lower end of the inclined surface 421 contacts the positioning part 31, the position of the key shaft core 3 is...

[0065] In some embodiments of this application, the button shaft 200 further includes a limiting member; the limiting member is used to limit the axial movement of the travel adjustment member 4. Due to the clearance fit between the travel adjustment member 4 and the top cover 12, the travel adjustment member 4 is rotatably sleeved on the button shaft core 3; for this connection method between the travel adjustment member 4 and the top cover 12, the addition of the limiting member limits the axial movement of the travel adjustment member 4, which can restrict the travel adjustment member 4 from moving in the vertical direction, making it easier to adjust the pressing stroke.

[0066] In some embodiments of this application, such as Figure 8As shown, the limiting member includes a recess (not shown) and a protrusion 122; the recess is disposed in the circumferential direction of the stroke adjusting member 4; the protrusion 122 is disposed on the top cover 12; the recess and the protrusion 122 cooperate to limit the axial movement of the stroke adjusting member 4, thereby restricting the upward movement of the stroke adjusting member 4 in the vertical direction.

[0067] In some embodiments of this application, such as Figure 9-10 As shown, the button shaft 200 also includes a locking member 6; the locking member 6 is disposed on the top cover 12; the locking member 6 cooperates with the stroke adjustment member 4 to limit the rotation of the stroke adjustment member 4.

[0068] In actual use, the travel adjustment component 4 may rotate slightly during user operation, thus altering the user's preset pressing stroke and affecting the user experience. Setting a limit component can restrict the rotation of the travel adjustment component 4, preventing accidental changes in the pressing stroke caused by accidental activation, which would affect the user's feel.

[0069] In some embodiments of this application, the top cover 12 is provided with a groove 121; the locking member 6 is movably disposed in the groove 121; the locking member 6 contacts the stroke adjusting member 4 and is used to restrict the rotation of the stroke adjusting member 4.

[0070] Specifically, when the locking member 6 moves within the groove 121 to contact the stroke adjusting member 4, it can restrict the rotation of the stroke adjusting member 4. In one embodiment, the locking member 6 includes a locking portion 62 and end portions 61 at both ends of the locking portion 62, with the end portions 61 disposed on the upper and lower sides of the groove 121; the locking portion 62 is located within the groove 121. The end portions 61 are used to limit the vertical movement of the locking member 6; the locking portions 62 are used to contact the stroke adjusting member 4 to restrict the rotation of the stroke adjusting member 4.

[0071] As can be seen from the above technical solution, this application has at least the following beneficial effects:

[0072] In the technical solution provided in this application embodiment, the switch component 2 in the key shaft 200 is triggered when the key shaft core 3 moves relative to the base 11, and the switch component 2 outputs a key switch signal; the travel adjustment component 4 is rotatably sleeved on the key shaft core 3. When the travel adjustment component 4 rotates, the positioning part 31 cooperates with the travel adjustment component 4 to position the key shaft core 3 to a preset horizontal height range, that is, to adjust the initial travel position range of the key shaft core 3; since the initial travel position of the key shaft core 3 changes, that is, the pressing travel of the key shaft core 3 changes, realizing the adjustment of the pressing travel of the key shaft core 3; and the pressing travel of the key shaft core 3 can also be adjusted within the range, making the pressing travel adjustment more flexible. Since the initial travel position of the key shaft core 3 changes, the triggering time of the switch component 2 also changes, realizing the adjustment of the triggering response speed of the key shaft 200. The key shaft 200 of this application allows for flexible adjustment and control of the pressing travel and triggering response speed, and the adjustment method is simple and convenient.

[0073] This application also provides a button, including a keycap and a button switch as described above; the keycap is disposed on the top of the button switch core. The button can be, but is not limited to, a keyboard key or a game controller key.

[0074] This application also provides an electronic device, which includes a key switch as described in the above technical solutions, or a key as described in the above technical solutions. The electronic device may be, but is not limited to, a game controller, a keyboard, etc.

[0075] 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.
