[0038] The following specific embodiments illustrate the implementation manners of the present application. Those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in this specification. Although the description of the present application will be introduced in conjunction with preferred embodiments, this does not mean that the features of this application are limited to this implementation manner. On the contrary, the purpose of introducing the application in conjunction with the implementation manner is to cover other alternatives or modifications that may be extended based on the claims of the present application. In order to provide a deep understanding of the present application, many specific details will be included in the following description. The present application can also be implemented without using these details. In addition, in order to avoid confusion or obscuring the key points of the present application, some specific details will be omitted in the description. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0039] Hereinafter, if used, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise stated, the meaning of "a plurality of" is two or more. The orientation terms such as "upper", "lower", "left", "right", etc. are defined relative to the orientation of the components shown in the drawings. It should be understood that these directional terms are relative concepts, and they are used for relative description and clarification, and they can change accordingly with the change of the orientation of the components placed in the drawings.
[0040] In the present application, if used, unless otherwise clearly defined and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or integrated; it can be directly connected or indirectly connected through an intermediate medium. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0041] The structural composition of the key includes a keycap and a key shaft body. When the user presses the keycap, the key shaft core in the key shaft body is driven to move downward until it moves to the bottommost position where the key shaft core can slide. The height difference between the initial position and the bottommost position of the key shaft core is the pressing stroke of the key shaft body. The stroke of the key shaft core moving relative to the base until it triggers the switch component on the base is the triggering stroke of the key shaft body. When the pressing speed of the user on the key remains unchanged, the shorter the triggering stroke of the key shaft body, the faster the triggering response speed; the longer the triggering stroke of the key shaft body, the slower the triggering response speed.
[0042] In the prior art, the pressing stroke of the key shaft is usually fixed and cannot be adjusted according to the user's usage habits and requirements. This may affect the user experience for some users with special requirements for key operations. For example, game players may require a shorter pressing stroke for quick response, while ordinary office users may prefer a longer pressing stroke for a more comfortable feel.
[0043] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe in detail the implementation manners of the present application with reference to the accompanying drawings.
[0044] Figure 1 The schematic structural diagram of the key provided by the embodiment of the present application is shown; Figure 2 The exploded view of the key provided by the embodiment of the present application is shown.
[0045] As Figure 1 、 2 shown, the key includes a keycap 100 and a key shaft 200; the keycap 100 is provided on the top of the key shaft core 3. After the user presses the keycap 100, the key shaft 200 can be pushed downward. In one implementation manner, the keycap 100 can be a round or square keycap 100.
[0046] Figure 3 The schematic structural diagram of the key shaft is shown; Figure 4 、 5 The exploded view of the key shaft is shown; Figure 6 The sectional view of the key shaft is shown.
[0047] As Figure 3-6 shown, a key shaft 200 of an embodiment of the present application, the key shaft 200 includes a housing 1, a switch assembly 2, a key shaft core 3, a stroke adjustment member 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 method, such as snap connection, threaded connection 41, etc., to form a relatively enclosed space for accommodating other components; in this embodiment, the switch assembly 2, the key shaft core 3, the stroke adjustment member 4, and the reset element 5 are located in this enclosed space.
[0049] As Figure 4-6 shown, the reset element 5, the reset element 5 is provided between the base 11 and the key shaft core 3. The key shaft core 3 is pressed downward from the initial position. After moving downward to a certain height, under the action of the reset element 5, the key shaft core 3 will rebound to the initial position. Exemplarily, the reset element 5 can be a spring. The spring has a first end and a second end, the first end cooperates with the base 11, and the second end cooperates with the bottom of the key shaft core 33. After the user presses the key shaft core 3, the spring rebounds the key shaft core 3 to the reset position.
[0050] As Figure 4-6 shown, the switch assembly 2 is disposed on the base 11. When the switch assembly 2 is triggered, a key switch signal is output.
[0051] The key shaft core 3 has a positioning portion 31. The key shaft core 3 is movably disposed in the housing 1, and the switch assembly 2 is triggered when the key shaft core 3 moves relative to the base 11.
[0052] In some embodiments of the present application, the switch assembly 2 is one of a mechanical switch, an optical induction switch, an electromagnetic induction switch, and an inductance induction switch.
[0053] In one embodiment, when the switch assembly 2 is a mechanical switch, the key shaft core 3 moves relative to the base 11 until the mechanical switch on the base 11 is triggered. At this time, that is, when the user presses the key shaft body 200 and reaches the trigger stroke of the key shaft body 200, the mechanical switch is turned on.
[0054] In one embodiment, when the switch assembly 2 is an optical induction switch, the optical induction switch outputs a signal by blocking or reflecting light.
[0055] The switch assembly 2 in the embodiments of the present application may also be an electromagnetic induction switch or an inductance induction switch, and the present embodiment does not limit this.
[0056] In this embodiment, the stroke adjustment member 4 is connected to the top cover 12, and the stroke adjustment member 4 is rotatably sleeved on the key shaft core 3. When the stroke adjustment member 4 rotates, the positioning portion 31 cooperates with the stroke adjustment member 4 to position the key shaft core 3 in a preset horizontal height interval to adjust the pressing stroke of the key shaft body 200.
[0057] Specifically, the key shaft core 3 has a positioning portion 31. When the positioning portion 31 is at different horizontal heights, that is, the key shaft core 3 is at different horizontal heights. The positioning portion 31 cooperates with the stroke adjustment member 4, and when the stroke adjustment member 4 rotates, the positioning portion 31 will be at different horizontal heights as the stroke adjustment member 4 rotates.
[0058] Exemplarily, the initial stroke position interval of the key shaft core 3 is preset to 0 - 1.5 mm, that is, the pressing stroke of the key shaft body 200 can be freely adjusted within the range of 0 - 1.5 mm. The initial stroke position interval of the key shaft core 3 may also be other range intervals, and the present embodiment does not limit this.
[0059] As Figure 6 shown, in some embodiments of the present application, the stroke adjustment member 4 is connected to the top cover 12 by a thread 41; the top of the positioning portion 31 contacts the bottom of the stroke adjustment member 4.
[0060] Specifically, threads 41 are provided on the mating surfaces of the stroke adjusting member 4 and the top cover 12. Since the stroke adjusting member 4 is rotatably sleeved on the key shaft core 3, the stroke adjusting member 4 can be adjusted by the user to move up and down. The top of the positioning portion 31 contacts the bottom of the stroke adjusting member 4. When the stroke adjusting member 4 rotates, the stroke adjusting member 4 will push the positioning portion 31, causing the key shaft core 3 to move in the vertical direction, so that the key shaft core 3 is positioned within a preset horizontal height range, thereby realizing the 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] Since the initial stroke position of the key shaft core 3 changes, the time to trigger the switch assembly 2 also changes, realizing the adjustment of the trigger response speed of the key shaft body 200. For the key shaft body 200 of the present application, the pressing stroke and the trigger response speed can be flexibly adjusted and controlled, and the adjustment method is simple and convenient.
[0062] Figure 7 The schematic connection diagram of the clearance fit between the stroke adjusting member and the top cover is shown; Figure 8 The cross-sectional view of the clearance fit between the stroke adjusting member and the top cover is shown.
[0063] The stroke adjusting member 4 and the top cover 12 are in clearance fit; a contact portion 42 is provided at the bottom of the stroke adjusting member 4, and the contact portion 42 has an inclined surface 421; when the stroke adjusting member 4 rotates, the inclined surface 421 cooperates with the positioning portion 31.
[0064] Specifically, when the stroke adjusting member 4 rotates, the inclined surface 421 on the contact portion 42 will push the positioning portion 31, causing the key shaft core 3 to move in the vertical direction, thereby realizing the adjustment of the pressing stroke. For example, when the higher end of the inclined surface 421 contacts the positioning portion 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 portion 31, the position of the key shaft core 3 is
[0065] In some embodiments of the present application, the key shaft body 200 further includes a limiting member; the limiting member is used for axially limiting the stroke adjusting member 4. Since the stroke adjusting member 4 and the top cover 12 are in clearance fit, the stroke adjusting member 4 is rotatably sleeved on the key shaft core 3; for this connection method of the stroke adjusting member 4 and the top cover 12, after adding the limiting member, axially limiting the stroke adjusting member 4 can limit the vertical movement of the stroke adjusting member 4, facilitating the adjustment of the pressing stroke.
[0066] In some embodiments of the present application, such as Figure 8As shown, the limiting member includes a concave portion (not shown) and a convex portion 122; the concave portion is provided in the circumferential direction of the stroke adjusting member 4; the convex portion 122 is provided on the top cover 12; the concave portion cooperates with the convex portion 122 to axially limit the stroke adjusting member 4, so as to limit the upward movement of the stroke adjusting member 4 in the vertical direction.
[0067] In some embodiments of the present application, as Figure 9-10 As shown, the key shaft body 200 further includes a locking member 6; the locking member 6 is provided on the top cover 12; the locking member 6 cooperates with the stroke adjusting member 4 to limit the rotation of the stroke adjusting member 4.
[0068] In actual use, the stroke adjusting member 4 may rotate to a certain extent during the user's use, thereby changing the preset pressing stroke of the user and affecting the user experience. By setting the limiting member, the rotation of the stroke adjusting member 4 can be restricted, avoiding the change of the pressing stroke caused by accidentally touching the stroke adjusting member 4 and affecting the user's touch feeling.
[0069] In some embodiments of the present application, the top cover 12 is provided with a groove 121; the locking member 6 is movably arranged in the groove 121; the locking member 6 contacts the stroke adjusting member 4 to limit the rotation of the stroke adjusting member 4.
[0070] Specifically, when the locking member 6 moves in the groove 121 to contact the stroke adjusting member 4, the rotation of the stroke adjusting member 4 can be restricted. In an embodiment, the locking member 6 includes a locking portion 62 and end portions 61 at both ends of the locking portion 62, and the end portions 61 are arranged on the upper and lower sides of the groove 121; the locking portion 62 is located in the groove 121. The end portions 61 are used to limit the locking member 6 in the vertical direction; the locking portion 62 is used to contact the stroke adjusting member 4 to limit the rotation of the stroke adjusting member 4.
[0071] It can be seen from the above technical solutions that the present application has at least the following beneficial effects:
[0072] In the technical solution provided by the embodiment of the present application, the switch assembly 2 in the key shaft body 200 is triggered when the key shaft core 3 moves relative to the base 11, and the switch assembly 2 outputs a key switch signal; the stroke adjustment member 4 is rotatably sleeved on the key shaft core 3. When the stroke adjustment member 4 rotates, the positioning portion 31 cooperates with the stroke adjustment member 4 to position the key shaft core 3 to a preset horizontal height interval, that is, the initial stroke position interval of the key shaft core 3 is adjusted; since the initial stroke position of the key shaft core 3 changes, that is, the pressing stroke of the key shaft core 3 changes, the adjustment of the pressing stroke of the key shaft core 3 is realized; and, the pressing stroke of the key shaft core 3 can also be adjusted within the interval range, and the pressing stroke adjustment is more flexible. Since the initial stroke position of the key shaft core 3 changes, the time to trigger the switch assembly 2 also changes, and the adjustment of the trigger response speed of the key shaft body 200 is realized. For the key shaft body 200 of the present application, the pressing stroke and the trigger response speed can be flexibly adjusted and controlled, and the adjustment method is simple and convenient.
[0073] The embodiment of the present application also provides a key, including a keycap and the key shaft body of the above technical solution; the keycap is arranged on the top of the key shaft core. The key can be, but is not limited to, a keyboard key or a key of a game controller.
