Description

Technical Field

[0001] This utility model relates to the field of keyboard technology, and in particular to an inductive switch and a keyboard. Background Technology

[0002] With the development of human-computer interaction input components, inductive switches have gained increasing popularity among consumers due to their advantages such as no physical contact wear, fast response speed, and high sensing accuracy. In existing technologies, some inductive switches employ an integrated button structure, with the button and inductive shaft fixedly connected. When the user presses the button, the button moves the inductive shaft vertically, changing the relative position between the inductive shaft and the inductor coil, thereby generating a recognizable inductance change signal and triggering the button. However, in actual use, the user's button pressing operation (such as non-standard pressing postures during rapid touch typing) often involves a certain tilt angle, subjecting the button to an eccentric force in a non-vertical direction. This eccentric force is directly transmitted to the inductive shaft, causing it to tilt synchronously with the button, which can easily lead to deviations in the inductance change signal, resulting in accidental button presses or trigger failure. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an inductive shaft.

[0004] This invention also proposes a keyboard having the inductive switch.

[0005] An inductive shaft according to a first aspect of the present invention includes a housing, a button, a spring, and an inductive shaft core. The housing has a cavity, and the top of the housing has a clearance hole communicating with the cavity. The button is slidably inserted through the clearance hole. The button includes an upper button and a lower button arranged vertically, which are movably connected. When the upper button is tilted down and moves the lower button down together, the lower button can move relative to the upper button. The spring is located between the bottom of the cavity and the lower button, and the inductive shaft core is located on the lower button.

[0006] An inductive shaft according to an embodiment of the present invention has at least the following beneficial effects: With the above structure, the button is configured as a movable upper button and a lower button. When the user tilts and presses the upper button, the tilting eccentric force of the upper button is not directly and rigidly transmitted to the lower button. The lower button can move relative to the upper button to reduce or eliminate the influence of the eccentric force, thereby effectively reducing or eliminating the tilt of the inductor shaft located on the lower button. This reduces the risk of signal deviation due to inductance changes, which could lead to accidental button presses or trigger failures. Furthermore, compared to traditional integrated buttons, the separate button design has a contact gap or mating gap (i.e., a "breakpoint" in vibration transmission). Therefore, it can significantly reduce noise transmitted through the button to the outside of the shaft, optimizing the user experience.

[0010] According to some embodiments of the present invention, the limiting post and the corresponding recess are respectively provided with a first arc surface and a second arc surface, the first arc surface and the second arc surface cooperate, and the limiting post and the corresponding recess can be in contact through the first arc surface and the second arc surface.

[0011] According to some embodiments of the present invention, the bottom of the cavity is provided with a guide cylinder, and the bottom of the lower button component, which is provided with the inductor shaft core, is slidably inserted into the inner cavity of the guide cylinder.

Detailed Implementation

[0018] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] In the description of this utility model, the use of terms such as first, second, third, fourth, and fifth is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0020] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In this utility model, unless otherwise explicitly defined, the terms "setting," "installing," and "connecting" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to a fixed connection, a detachable connection, or an integral molding; they can refer to a mechanical connection; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Reference Figures 1 to 5 This utility model provides an inductive shaft, which includes a housing 100, a button 200, a spring 300, and an inductive shaft core 400.

[0023] The housing 100 has a cavity S1 inside, and the top of the housing 100 has a clearance hole 110 communicating with the cavity S1. The button 200 is slidably inserted through the clearance hole 110. The button 200 includes an upper button 210 and a lower button 220 arranged vertically. The upper button 210 and the lower button 220 are movably connected so that when the upper button 210 is tilted down and moves the lower button 220 down together, the lower button 220 can move relative to the upper button 210. A spring 300 is disposed between the bottom of the cavity S1 and the lower button 220. The spring 300 can drive the lower button 220 to remain in contact with the upper button 210 and can drive the button 200 to move up and reset. An inductor shaft 400 is disposed on the lower button 220.

[0024] With the above structure, the button 200 is configured as an upper button 210 and a lower button 220 that can be movably connected. When the user tilts and presses the upper button 210, the tilting eccentric force of the upper button 210 is not directly and rigidly transmitted to the lower button 220. The lower button 220 can move relative to the upper button 210 to reduce or eliminate the influence of the eccentric force, thereby effectively reducing or eliminating the tilt of the inductor shaft 400 located on the lower button 220. This reduces the problem of signal deviation caused by inductance changes, leading to accidental button presses or trigger failures. In addition, compared with the traditional integrated button 200, the separate button 200 has a contact gap or mating gap (i.e., a "breakpoint" in vibration transmission). Therefore, it can greatly reduce the noise transmitted to the outside of the shaft through the button 200, optimizing the user experience.

[0025] In this embodiment, refer to Figures 1 to 3 The housing 100 includes an upper cover and a base connected vertically, which together form the cavity S1. The upper cover is provided with the clearance hole 110. The spring 300 can drive the button 200 to move upward to abut against the upper cover to reset to the initial state.

[0026] In this embodiment, refer to Figures 2 to 5 The upper button 210 is movably fitted onto the lower button 220. Specifically, the bottom of the upper button 210 is provided with four limiting posts 211, and the four limiting posts 211 surround a connecting space S2. The upper button 210 is movably fitted onto the lower button 220 through the connecting space S2.

[0027] Understandably, referring to Figure 5 A movable gap S3 is provided between the side of the socket space S2 and the part of the lower button 220 that is socketed, and the movable gap S3 allows the lower button 220 to move relative to the upper button 210.

[0028] It is understandable that when the user tilts and presses the upper button 210, the lower button 220 can move relative to the upper button 210 to reduce or eliminate the effect of the eccentric force.

[0029] In some embodiments, the limiting posts 211 are configured to be three, five, etc.

[0030] In some embodiments, the limiting post 211 is provided on the lower button 220, and the lower button 220 is movably sleeved on the upper button 210 through the sleeve space S2 enclosed by the four limiting posts 211.

[0031] In some embodiments, the bottom of the upper button 210 is provided with a socket cavity, through which the upper button 210 is movably sleeved on the lower button 220. A movable gap S3 is provided between the cavity wall of the socket cavity and the sleeved portion of the lower button 220.

[0032] In this embodiment, refer to Figures 3 to 5 The lower button 220 has four recesses 221 on its periphery, and four limiting posts 211 are correspondingly inserted into the four recesses 221. The limiting posts 211 and the corresponding recesses 221 are respectively provided with a first arc surface 211A and a second arc surface 221A. The first arc surface 211A and the second arc surface 221A cooperate, allowing the limiting posts 211 and the corresponding recesses 221 to contact each other through the first arc surface 211A and the second arc surface 221A.

[0033] With the above structure, on the one hand, the recess 221 accommodating the limiting post 211 can reduce the overall volume of the split button 200, thereby improving the compactness of the split button 200; on the other hand, when the user tilts and presses the upper button 210, the corresponding limiting post 211 can contact the corresponding recess 221 through the first arc surface 211A and the second arc surface 221A. The arc surface design increases the force-bearing area, thereby dispersing stress and reducing the probability of damage.

[0034] In this embodiment, refer to Figure 2 and Figure 3 The base has a guide cylinder 120 located at the bottom of the cavity S1. The bottom of the lower button 220 with an inductor shaft 400 is slidably inserted into the inner cavity of the guide cylinder 120. The bottom of the base has an extension cylinder 130, the inner cavity of the extension cylinder 130 is connected to the inner cavity of the guide cylinder 120, and the inductor shaft 400 located at the bottom of the lower button 220 is slidably inserted into the inner cavity of the extension cylinder 130.

[0035] With the above structure, on the one hand, under the action of the guide tube 120, the button 200 can move up and down more accurately; on the other hand, it can be understood that when the switch of this application is installed on the keyboard, the inductor coil on the keyboard circuit board can be sleeved on the outside of the extension tube 130. Therefore, when the inductor core 400 moves in the inner cavity of the extension tube 130, it can cause a change in inductance and trigger a signal. In addition, compared with the conventional inductor switch opening design (the conventional inductor switch base has a through hole for the inductor core 400 to extend out), the design of the extension tube 130 can prevent external debris (such as dust) from entering through the through hole and contaminating the cavity S1.

[0036] This invention also proposes a keyboard that includes the aforementioned inductive switch. This structure reduces the problem of signal deviation caused by changes in inductance, which could lead to accidental key presses or trigger failure.

[0037] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
