Induction module and magnetic shaft keyboard

Abstract

This utility model discloses a sensing module and a magnetic axis keyboard. The sensing module includes a substrate and a Hall effect assembly. The substrate has a facing portion, and the Hall effect assembly includes at least three first Hall elements evenly disposed on the substrate, with the at least three first Hall elements uniformly arranged around the axis of the facing portion. With this structure, after the sensing module is assembled onto the magnetic axis keyboard, the facing portion is directly below the magnet. The at least three first Hall elements uniformly arranged around the axis of the facing portion are also uniformly arranged around the axis of the magnet. Therefore, the at least three first Hall elements of the Hall effect assembly can form a multi-point collaborative detection network. Thus, the magnetic axis keyboard's processing system can accurately identify whether the magnet is in a tilted pressing state rather than a vertical release state by comprehensively comparing the magnetic field change data of multiple first Hall elements, thereby greatly reducing or avoiding the occurrence of misjudgment of keycap release (disconnection of the pressing signal).

Description

Technical Field

[0001] This utility model relates to the field of Hall effect technology, and in particular to a sensing module and a magnetic axis keyboard. Background Technology

[0002] A magnetic axis keyboard is a type of keyboard developed based on Hall effect technology. It triggers a signal through changes in magnetic field. Specifically, the magnetic axis button on the keyboard has a magnet. When the user presses the keycap, causing the button connected to the keycap to move down, the position of the magnet changes. The Hall element on the keyboard senses the change in magnetic field strength and converts it into an electrical signal to trigger a response. However, after market research and in-depth study, the inventors discovered that existing magnetic axis keyboards use a single Hall element under each magnetic axis to sense changes in magnetic field. When the user presses the keycap for a long time, the force applied to the keycap may not be entirely along the axial direction. These non-axial forces can easily cause the magnet to shift laterally, causing the Hall element to sense changes in magnetic field strength. Therefore, it is easy to misjudge that the keycap has been released (the press signal has been disconnected). 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 a sensing module.

[0004] This invention also proposes a magnetic shaft keyboard with the sensing module.

[0005] According to a first aspect of the present invention, a sensing module includes a substrate and a Hall effect assembly. The substrate has an opposing portion, and the Hall effect assembly includes at least three first Hall elements evenly disposed on the substrate. The at least three first Hall elements are evenly arranged around the axis of the opposing portion.

[0006] A sensing module according to an embodiment of the present invention has at least the following beneficial effects:

[0007] With the above structure, after the sensing module of this application is assembled into the magnetic axis keyboard, on the one hand, the facing part is directly below the magnet of the corresponding magnetic axis, and at least three first Hall elements are evenly arranged along the axis of the facing part, i.e., the axis of the magnet is evenly arranged. Therefore, the at least three first Hall elements of the Hall assembly can form a multi-point collaborative detection network. Thus, when the user presses the keycap at an angle, causing the magnet to shift laterally, the first Hall element in the direction of the shift detects an increase in magnetic field, while the first Hall element in the opposite direction detects a decrease in magnetic field. In this regard, the processing system of the magnetic axis keyboard can accurately identify that the magnet is in an inclined pressing state rather than a vertical release state by comprehensively comparing the magnetic field change data of multiple first Hall elements, thus greatly reducing or avoiding the situation of false keycap release (disconnection of pressing signal). On the other hand, the evenly distributed first Hall elements cover the circumferential displacement monitoring area of ​​the magnet. No matter which direction the magnet shifts, at least two or more first Hall elements can simultaneously capture the differentiated magnetic field signals, ensuring that the processing system of the magnetic axis keyboard always determines the keycap state based on multi-dimensional data fusion, greatly reducing the false trigger rate.

[0008] According to some embodiments of the present invention, the opposite portion is provided with a second Hall element.

[0009] According to some embodiments of the present invention, the first Hall element and the second Hall element are both located on the same side of the substrate.

[0010] According to some embodiments of the present invention, the Hall component includes three first Hall elements, which are arranged in a triangular three-point configuration.

[0011] According to some embodiments of the present invention, both the opposing portion and the Hall assembly are configured as at least two, and the opposing portions corresponding to at least three of the first Hall element rings of the Hall assembly are evenly arranged.

[0012] According to some embodiments of the present invention, the Hall component includes a housing disposed on the substrate, and at least three first Hall elements of the Hall component are disposed on the housing to be disposed on the substrate via the housing.

[0013] According to some embodiments of the present invention, one of the first Hall elements and the other of the first Hall elements are arranged to rotate and coincide with the axes of the opposite portions.

[0014] According to a second aspect of the present invention, a magnetic axis keyboard includes a sensing module as described above.

[0015] The magnetic axis keyboard according to the present invention has at least the following beneficial effects: the above structure can greatly reduce or avoid the occurrence of misjudged keycap release (disconnection of press signal).

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] Reference Figure 1 and Figure 2 This utility model provides a sensing module, which includes a substrate 100 and a Hall component 200. The substrate 100 has a facing portion 110. The Hall component 200 includes three first Hall elements 210 evenly disposed on the substrate 100. The three first Hall elements 210 are all located on the lower side of the substrate 100, and the three first Hall elements 210 are evenly arranged around the axis of the facing portion 110.

[0034] Understandably, the substrate 100 can be configured as a PCB module that can serve as a keyboard processing system, the first Hall element 210 is electrically connected to the substrate 100, and the substrate 100 is used for mounting the magnetic shaft 400.

[0035] With the above structure, after the sensing module of this application is assembled into the magnetic axis keyboard, on the one hand, the facing part 110 is directly opposite to the magnet of the corresponding magnetic axis 400. The three first Hall elements 210 are evenly arranged around the axis of the facing part 110, which is also evenly arranged around the axis of the magnet. Therefore, the three first Hall elements 210 of the Hall component 200 can form a multi-point collaborative detection network. It can be seen that when the user presses the keycap at an angle, causing the magnet to shift laterally, the first Hall element 210 in the offset direction detects an increase in magnetic field, while the first Hall element 210 in the opposite direction detects a decrease in magnetic field. In this regard, the processing system of the magnetic axis keyboard can accurately identify that the magnet is in an inclined pressing state rather than a vertical release state by comprehensively comparing the magnetic field change data of multiple first Hall elements 210. Therefore, it can greatly reduce or avoid the situation of misjudging the keycap release (the pressing signal is disconnected). On the other hand, the evenly distributed first Hall elements 210 cover the circumferential displacement monitoring area of ​​the magnet. Regardless of which direction the magnet is deflected, at least two first Hall elements 210 can simultaneously capture differentiated magnetic field signals, ensuring that the magnetic axis keyboard's processing system always determines the keycap status based on multi-dimensional data fusion, significantly reducing the false trigger rate.

[0036] Understandably, the sensing module of this application can also be installed in electronic products that use Hall effect technology, such as game controllers.

[0037] In some embodiments, the three first Hall elements 210 may be disposed on the upper side of the substrate 100.

[0038] In this embodiment, refer to Figure 1 and Figure 2 The three first Hall elements 210 are arranged in a triangle at three points, and the axes of one first Hall element 210 and the other first Hall element 210 are rotated to coincide with the axis of the ring facing part 110.

[0039] In some embodiments, the Hall component 200 includes four first Hall elements 210 evenly disposed on the substrate 100. The four first Hall elements 210 are all located on the lower side of the substrate 100. The axes of the four first Hall elements 210 are evenly arranged around the facing portion 110. The four first Hall elements 210 are arranged in a square at four points. The axes of one first Hall element 210 and the other first Hall element 210 are rotated to coincide with the axes of the facing portion 110.

[0040] Understandably, users can set the number of the first Hall element 210 of the Hall assembly 200 to four, five, six, etc., according to their actual usage needs.

[0041] In some embodiments, refer to Figure 3 and Figure 4The facing portion 110 is provided with a second Hall element 300, and both the first Hall element 210 and the second Hall element 300 are located on the lower side of the substrate 100. The second Hall element 300 is added at the center of the facing portion 110 to ensure the axial detection accuracy of the sensing module of this application.

[0042] In some embodiments, both the facing portions 110 and the Hall components 200 are provided in at least two configurations, and the facing portions 110 corresponding to the three first Hall element 210 rings of the Hall components 200 are evenly distributed. It is understood that the number of facing portions 110 and Hall components 200 corresponds to the number of magnetic shafts 400 mounted on the substrate 100.

[0043] In some embodiments, refer to Figure 5 and Figure 6 The Hall component 200 includes a housing 220 disposed on the underside of the substrate 100. The three first Hall elements 210 of the Hall component 200 are all disposed on the housing 220 and disposed on the substrate 100 through the housing 220. The first Hall elements 210 are electrically connected to the housing 220.

[0044] With the above structure, all three first Hall elements 210 are disposed in the housing 220, enabling modular integration of the Hall assembly 200. Therefore, during the production and installation of the sensing module, the three first Hall elements 210 can be simultaneously installed on the substrate 100 by mounting the housing 220 on the substrate 100.

[0045] This invention also proposes a magnetic axis keyboard, which includes the aforementioned sensing module. This structure significantly reduces or avoids the occurrence of misjudged keycap release (disconnection of the press signal).

[0046] Of course, this utility model is not limited to the above-described embodiments.

All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
