Description

Technical Field

[0001] The present application relates to the field of input devices, and in particular to a center-bottoming magnetic axis key. Background Art

[0002] In the prior art, the design of magnetic axis keys usually adopts a structure in which the magnetic column is installed from the bottom of the handle. This structure requires a hole to be opened at the bottom of the handle so that the magnetic column can be installed into the handle from bottom to top. Although this design can realize the basic functions of magnetic axis keys, it has some significant disadvantages in practical applications.

[0003] For mechanical buttons, sound feedback is an important parameter that directly affects consumers' usage experience and product purchasing choices.

[0004] Due to the opening at the bottom of the handle of traditional magnetic axis keys, the sound produced during operation is often scattered and chaotic, and the sound concentration is not high. According to the position of the magnet in the hole, there are three main types of conventional magnetic axis key designs: the outer periphery of the core column touches the bottom, the magnet touches the bottom, and the two sides of the handle touch the bottom.

[0005] In the design where the outer periphery of the stem touches the bottom, the middle of the key is empty, resulting in a less focused and clear sound when the key is operated. The design where the magnet touches the bottom makes the key sound hard and less pleasant. The design where the two sides of the handle touch the bottom also makes the sound scattered and messy due to the collision on both sides of the key. None of these three designs are as pleasant and satisfying as the sound produced by plastic hitting plastic. Utility Model Content

[0006] The purpose of the present application is to overcome at least one of the shortcomings of the prior art and to provide a center-touching magnetic axis button, which installs the magnetic column from the upper part of the button handle so that the lower end of the button handle is sealed as a solid bottom. When the button is operated, the sound is clearer and more concentrated, and the sound emitted is more pleasant, which significantly improves the user experience.

[0007] To achieve the above-mentioned purpose, the present application discloses a center-touch-bottom magnetic axis button, comprising a main body, a button handle that is repositionable and movably installed in the main body, a magnetic column arranged in the button handle, and a Hall sensing device located on one side of the bottom surface of the main body and aligned with the magnetic column, wherein the bottom end of the button handle is a sealed solid bottom that cooperates with the bottom of the main body. When the button is working, the bottom end of the button handle contacts and collides with the bottom of the main body to provide a button feedback sound.

[0008] Further, the button handle is composed of a main part located at the top and a detachable part located at the bottom, and the main part and the detachable part are axially plugged in and connected; the lower end of the detachable part is a solid bottom, and a mounting groove is provided downward at the top of the detachable part, and the bottom of the mounting groove is close to the solid bottom end of the button body; the magnetic column is inserted from the top of the button body and fixed in the mounting groove.

[0009] Furthermore, a position for installing a key cap is provided at the top of the main component.

[0010] Furthermore, the lower section of the disassembled component is columnar.

[0011] Furthermore, a plastic impact block is provided at the bottom end of the disassembled part.

[0012] Furthermore, the main body is provided with a vertical linear guide groove, and correspondingly, a guide block cooperating with the linear guide groove is protruded laterally on the main part of the handle, and the cooperation between the linear guide groove and the guide block realizes the guidance of the handle when it moves in the vertical direction.

[0013] Furthermore, the body is composed of a base and a cover. The body is hollow, forming a chamber for accommodating and installing the handle. The upper end of the chamber is open, and the handle part extends out of the opening.

[0014] Furthermore, the push handle is connected to the base through at least one elastic element, and the push handle is reset after being moved downward via the elastic element.

[0015] Furthermore, the elastic element is a coil spring.

[0016] Furthermore, the body is mounted on the front side of a PCB circuit board, and the Hall sensor is mounted on the back side of the PCB circuit board.

[0017] Furthermore, the Hall sensing device is a Hall chip.

[0018] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0019] Sound feedback optimization: The bottom of the button handle contacts and collides with the bottom of the body, providing a concentrated and clear button feedback sound, significantly improving the user experience.

The term "and / or" used in the specification includes any and all combinations of one or more of the relevant listed items. Example

[0031] like Figures 1 to 4 As shown, this embodiment discloses an exemplary structure for achieving the technical purpose of the present application, specifically a center-touching magnetic axis button.

[0032] Structurally, the button includes a body 1 made of non-magnetic material, a resettable handle 2 movably installed in the body 1, a magnetic column 3 arranged in the handle 2, and a Hall sensor 4 located on one side of the bottom surface of the body 1 and aligned with the magnetic column 3.

[0033] In this embodiment, the body 1 is mounted on the front side of the PCB circuit board 5 , and the Hall sensing device 4 is mounted on the back side of the PCB circuit board 5 . The Hall sensing device 4 is a Hall chip.

[0034] It is understandable that the Hall sensor device is preferably a Hall chip, which is small in size, highly sensitive and fast in response. The Hall chip can monitor the operation status of the key in real time by cooperating with the magnetic column 3 to ensure the accuracy and reliability of the key operation.

[0035] In the specific structure, the button handle 2 is composed of a main part 201 located at the top and a sub-part 202 located at the bottom. The main part 201 and the sub-part 202 are plugged in and connected axially. As an engineering common sense, at least the sub-part 202 is a non-magnetic plastic part.

[0036] The sealed solid bottom 203 of the button handle 2 cooperates with the bottom 101 of the body 1. When the button is working, the sealed solid bottom 203 of the button handle 2 contacts and collides with the bottom 101 of the body 1 to provide a button feedback sound.

[0037] In this embodiment, the body 1 is composed of a base 102 and a cover 103, and is made of non-magnetic materials, such as ABS plastic or polycarbonate, to ensure that magnetic interference is avoided. The base 102 of the body 1 cooperates with the cover 103 to form a chamber 105 for accommodating and installing the handle 2.

[0038] More specifically, a vertical linear guide groove 106 is provided on the main body 1, and a guide block 204 cooperating with the linear guide groove 106 is protruded laterally on the main part 201 of the handle 2. The linear guide groove 106 and the guide block 204 cooperate with each other to achieve guidance of the handle 2 when it moves in the vertical direction.

[0039] More specifically, in this embodiment, the button handle 2 is connected to the base 102 via at least one elastic element 104 , and the button handle 2 is reset after being moved downward via the elastic element 104 .

[0040] Preferably, the elastic element 104 adopts a coil spring. The advantages of the coil spring are stable elastic force, long service life and good reset effect. The spring material can be steel or stainless steel to ensure that the handle 2 can maintain good reset performance in long-term use and extend the service life of the key.

[0041] More specifically, in this embodiment, the main component 201 and the detachable component 202 of the push handle 2 are connected by plugging, thereby ensuring the stability of the push handle 2 in the vertical direction.

[0042] In this embodiment, a mounting groove 205 is provided downwardly at the top of the disassembly component 202, and the bottom of the mounting groove 205 is close to the sealing solid bottom 203 of the button handle 2. The magnetic column 3 is inserted from the top of the disassembly component 202 and fixed in the mounting groove 205, which simplifies the installation process of the magnetic column 3 and ensures the stability of the magnetic column 3 in the button.

[0043] In more detail, the material of the disassembly part 202 can be selected from POM (polyoxymethylene) or other engineering plastics, which have excellent mechanical strength and wear resistance. For example, different plastic materials and hardness will affect the timbre and volume when impacted, which can be customized according to the user's preferences. This design not only improves the sound feedback quality of the key, but also increases the personalization and diversity of the product, meeting the needs of different users.

[0044] As an optional technical solution, a plastic impact block (not shown in the figure) is provided at the bottom of the disassembly component 202 for achieving tone control. Different impact sounds can be produced by selecting different plastic materials and designs, thereby making the product more flexible.

[0045] In this embodiment, the magnetic column preferably uses high-strength magnetic materials, such as neodymium iron boron magnets (NdFeB), to provide stable magnetic force. The magnetic column is aligned with the Hall sensor device, and the Hall sensor device detects the position change of the magnetic column to achieve accurate detection of key operations.

[0046] In terms of working principle, when the user presses the button, the button handle moves downward along the vertical direction of the body under the guidance of the vertical guide groove and the guide block. As the button handle moves downward, the magnetic column also moves with it. When the button handle moves downward to a certain position, the bottom of the button handle collides with the bottom of the body. This collision produces a crisp and pleasant sound feedback, and the user can feel the state of the button being pressed through hearing. This sound feedback effect can be achieved by selecting different plastic materials and designs to meet the needs of different users.

[0047] At the same time, the Hall sensor 4 detects the position change of the magnetic column 3, generates a corresponding electrical signal, and transmits it to the PCB circuit board 5 for further processing. The Hall chip can detect the displacement of the magnetic column 3 with high sensitivity, ensuring the accuracy and reliability of the key operation. When the user releases the key, the elastic force of the elastic element 104 quickly resets the handle 2, and the handle 2 and the magnetic column 3 return to their initial positions. The Hall sensor 4 also detects the position change of the magnetic column 3, and the key operation detection process ends.

[0048] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims. The present disclosure is defined by the appended claims, and the equivalents of these claims are also included.
