[0052] The following specific embodiments illustrate the implementation of the present application, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. Although the description of the present application will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this application are limited to the implementation. On the contrary, the purpose of introducing the application in conjunction with the implementation is to cover other options 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, the following description will include many specific details. The present application can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present application, some specific details will be omitted in the description. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0053] Hereinafter, if used, the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more. Positional terms such as "upper", "lower", "left", and "right" are defined relative to the orientation of the components schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts. They are used for description and clarification relative to the components, and may change accordingly according to changes in the orientation of the components placed in the accompanying drawings.

[0054] In this application, if used, unless otherwise expressly specified and limited, the term "connection" should be understood in a broad sense, for example, "connection" can be fixed connection, detachable connection, or integrated; 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 relevant listed items.

[0055] Commonly used keyboards, such as office keyboards, gaming keyboards, etc., contain various types of keys. From the appearance point of view, the key type can be a key with a round keycap or a key with a square keycap; from the function point of view, the key type can be a key with different pressing travels and a key with different trigger response speeds.

[0056] The key structure consists of a keycap and a key shaft. When the user presses the keycap, the key shaft in the key shaft moves downward until it moves to the bottom position where the key shaft can slide. The height difference between the initial position and the bottom position of the key shaft is the pressing stroke of the key shaft. The stroke of the key shaft moving from the initial position relative to the base until the switch assembly on the base is triggered is the trigger stroke of the key shaft. When the user's pressing speed on the key remains unchanged, the shorter the trigger stroke of the key shaft, the faster the trigger response speed; the longer the trigger stroke of the key shaft, the slower the trigger response speed.

[0057] Therefore, the trigger stroke of the key shaft is not equal to the pressing stroke of the key shaft. The key shaft moves from the initial position relative to the base until it triggers the travel of the switch assembly on the base. At this time, although the switch assembly is triggered and outputs a key switch signal, the key shaft has not yet contacted the base and continues to move relative to the base. At this time, the pressing stroke of the key shaft is greater than the trigger stroke of the key shaft. Only when the switch assembly is triggered, the key shaft moves down to the bottom position where the key shaft can slide. At this time, the pressing stroke of the key shaft is equal to the trigger stroke of the key shaft.

[0058] The key pressing stroke of the existing keyboard is fixed, and the user cannot adjust the pressing stroke according to their own needs. In addition, the trigger response speed of the key triggered by a single stroke cannot be adjusted, resulting in a poor user experience.

[0059] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0061] Figure 1 , 2 A key 100 is shown, comprising a key cap 1001 and a key shaft 200; the key cap 1001 is arranged on the top of the key shaft core 3. When a user presses the key cap 1001, the key shaft 200 can be driven to move downward. In one embodiment, the key cap 1001 can be a round or square key cap 1001.

[0062] Figure 3 A schematic diagram of the structure of a key shaft with adjustable pressing stroke is shown; Figure 4 A disassembled view of a key shaft with adjustable pressing stroke is shown.

[0063] like Figure 3 , 4As shown, a key shaft 200 with adjustable pressing stroke according to an embodiment of the present application includes a housing 1, a switch assembly 2, a key shaft core 3, a stroke adjusting member, and a reset element 7.

[0065] Figure 5 The schematic diagram of the structure of the switch assembly is shown. The switch assembly 2 is arranged on the base 11, and when the switch assembly 2 is triggered, the switch signal of the button 100 is output;

[0066] The key shaft core 3 has a positioning portion 31; the key shaft core 3 is movably arranged in the shell 1, and the switch component 2 is triggered when the key shaft core 3 moves relative to the base 11; in some embodiments of the present application, the switch component 2 is one of a mechanical switch 21, an optical sensing switch 22, an electromagnetic induction switch 23, and an inductive sensing switch 24.

[0067] See also Figure 5 When the switch assembly 2 is a mechanical switch 21, the key shaft core 3 moves relative to the base 11 until the mechanical switch 21 on the base 11 is triggered, that is, the user presses the key shaft body 200 and reaches the trigger stroke of the key shaft body 200, at which time the mechanical switch 21 is turned on.

[0068] Exemplarily, 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 key shaft 200 and reaches the trigger stroke of the key shaft 200 , the spring terminal 211 is triggered and outputs a switch signal of the key 100 .

[0069] See also Figure 6 When the switch assembly 2 is an optical sensing switch 22, the optical sensing switch 22 includes a light emitter (not shown) and a light receiver (not shown), both of which are arranged on the base 11. When the key shaft core 3 moves relative to the base 11 and reaches a preset position, the key shaft core 3 blocks the light receiver from sensing the light source to reach a preset intensity range, and at this time, the trigger stroke of the key shaft body 200 is reached, and at this time, the optical sensing switch 22 is turned on.

[0070] See also Figure 7When 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 arranged on the key shaft core 3, and the Hall sensor is arranged on the base 11. When the key shaft core 3 moves relative to the base 11 and reaches a preset position, the Hall device outputs a trigger instruction.

[0071] See also Figure 8 When the switch assembly 2 is an inductive induction switch 24, the inductive induction switch 24 includes an electromagnetic induction coil and a sensing rod for induction by the electromagnetic induction coil, the sensing rod is arranged on the key shaft core 3, and the electromagnetic induction coil is arranged on the base 11. When the key shaft core 3 moves relative to the base 11 and reaches a preset position, the electromagnetic induction coil outputs a trigger instruction when it reaches a preset current threshold.

[0072] See also Figure 4 In some embodiments of the present application, the reset element 7 is disposed between the base 11 and the key shaft core 3. The reset element 7 may be a reset spring having a first end and a second end, wherein the first end cooperates with the base 11 and the second end cooperates with the bottom of the key shaft core 3. After the user presses the key shaft core 3, the reset spring rebounds the key shaft core 3 to its original position.

[0073] See also Fig. 9 The stroke adjustment member of the embodiment of the present application includes a plurality of stroke stop areas 4 with different horizontal heights; the stroke stop area 4 is arranged in the shell 1; the positioning portion 31 is respectively cooperated with the plurality of stroke stop areas 4 with different horizontal heights, so as to position the key shaft core 3 to different horizontal heights to adjust the pressing stroke of the key shaft body 200.

[0074] Specifically, 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 switch signal of the key 100; the positioning portion 31 of the key shaft core 3 cooperates with the multiple horizontal travel stop areas 4 of different heights in the travel adjustment member to position the key shaft core 3 to different horizontal heights, that is, the initial travel position of the key shaft core 3 is adjusted; when the key shaft core 3 moves relative to the base 11, the initial travel position of the key shaft core 3 changes, that is, the pressing travel of the key shaft core 3 changes, and the pressing travel of the key shaft core 3 is adjusted; and when the key shaft core 3 moves relative to the base 11, the initial travel position of the key shaft core 3 changes, and the time to trigger the switch assembly 2 also changes, so that the trigger response speed of the key shaft body 200 is adjusted. The key shaft body 200 of the present application has adjustable control of the pressing travel and the trigger response speed, and the adjustment method is simple and convenient, and there is no need to replace the key 100. The user can reasonably set it according to their own needs to improve the user experience.

[0075] The travel stop area 4 of the present application is arranged in the shell 1, and cooperates with a plurality of travel stop areas 4 with different horizontal heights through the positioning portion 31. The user only needs to adjust the internal structure of the key shaft 200 without adjusting the keycap 1001. It is suitable for adjusting the pressing stroke of the key 100 with a square keycap 1001 or the key 100 with a round keycap 1001, and the pressing stroke and the trigger response speed can be adjusted and controlled.

[0076] like Fig. 9 As shown, the travel stop area 4 is fixedly arranged in the housing 1; the travel adjustment member also includes a movable member 5; when the movable member 5 is movable, the positioning portion 31 respectively cooperates with a plurality of travel stop areas 4 with different horizontal heights.
