Description

Center-bottomed magnetic axis buttons Technical Field

[0001] This application relates to the field of input devices, and in particular to a center-bottomed magnetic axis key. Background Technology

[0002] In existing technology, magnetic axis buttons are typically designed with a structure in which the magnetic core is inserted from the bottom of the button. This structure requires a hole to be drilled at the bottom of the button to insert the magnetic core from bottom to top. While this design achieves the basic function of a magnetic axis button, it has some significant drawbacks in practical applications.

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

[0004] Traditional magnetic axis buttons, due to the opening at the bottom of the button, often produce a scattered and chaotic sound during operation, lacking focus. Based on the position of the magnet within the slot, conventional magnetic axis button designs fall into three main categories: bottoming out from the outer edge of the button post, bottoming out with the magnet itself, and bottoming out from both sides of the button.

[0005] In designs where the button's core is bottomed out from the periphery, the hollow center results in a less focused and clear sound during button operation. Magnetic bottoming makes the button sound harsh and less pleasant. Bottoming out from the sides of the button, due to the impact on both sides, also produces a scattered and chaotic sound. None of these three designs produce a sound as pleasant and satisfying as the sound of plastic striking plastic. Utility Model Content

[0006] The purpose of this application is to overcome at least one deficiency of the prior art and provide a center-bottomed magnetic shaft button. This button inserts the magnetic column from the top of the handle, making the bottom of the handle sealed as a solid bottom. The button operation produces a clearer and more focused sound, and the sound is more pleasant, significantly improving the user experience.

[0007] To achieve the above objectives, this application discloses a center-bottom-contact magnetic shaft button, comprising a body, a resettable handle movably installed within the body, a magnetic post disposed within the handle, and a Hall effect sensor located on one side of the bottom surface of the body and aligned with the magnetic post. The bottom end of the handle is a sealed solid bottom that mates with the bottom of the body. When the button is in operation, the bottom end of the handle contacts and collides with the bottom of the body, providing button feedback sound.

[0008] Further, the handle is composed of an upper main part and a lower detachable part, which are connected in an axial direction; the lower end of the detachable part is a solid bottom, and the top end of the detachable part is provided with a mounting groove, which is close to the solid bottom end of the key body; the magnetic column is inserted into and fixed in the mounting groove from the top end of the key body.

[0009] Further, the top end of the main part is provided with a clamping position for the key cap installation.

[0010] Further, the lower section of the detachable part is in a columnar shape.

[0011] Further, the bottom end of the detachable part is provided with a plastic impact block.

[0012] Further, the body is provided with a vertical linear guide groove, and the upper side of the main part of the handle is provided with a guide block matched with the linear guide groove, so as to realize the guidance when the handle runs in the vertical direction.

[0013] Further, the body is composed of a base and a cover, and is hollow to form a cavity for accommodating and installing the handle, and the cavity is open at the upper end, and the handle partially extends from the opening.

[0014] Further, the handle and the base are connected and matched through at least one elastic element, so as to reset the handle after it goes down.

[0015] Further, the elastic element is a spiral spring.

[0016] Further, the body is installed on the front surface of a PCB circuit board, and the Hall induction device is installed on the back surface of the PCB circuit board.

[0017] Further, the Hall induction device is a Hall chip.

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

[0019] Sound feedback optimization: the bottom end of the handle contacts and collides with the bottom of the body, providing concentrated and clear key feedback sound, significantly improving the user's experience.

[0020] Simplified assembly and maintenance: the magnetic column is inserted into and fixed in the mounting groove from the top end of the handle, which simplifies the assembly process and facilitates subsequent maintenance and replacement. This design not only improves production efficiency, but also reduces manufacturing cost.

[0031] As shown in Figs. 1-4, the present embodiment discloses an exemplary structure for achieving the technical purpose of the present application, specifically a center-touch bottom magnetic shaft key.

[0032] In structure, the key comprises a body 1 made of non-magnetic material, a push handle 2 resettable movably mounted in the body 1, a magnetic column 3 arranged in the push handle 2, and a Hall sensing device 4 located on one side of the bottom surface of the body 1 and matched with the magnetic column 3.

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

[0034] It can be understood that the Hall sensing device is preferably a Hall chip, which has small volume, high sensitivity and fast response speed. The Hall chip can monitor the operation state of the key in real time through cooperation with the magnetic column 3, thereby ensuring the operation accuracy and reliability of the key.

[0035] In the specific structure, the push handle 2 of the key is composed of an upper main part 201 and a lower disassembled part 202, and the main part 201 and the disassembled part 202 are connected in axial insertion, wherein at least the disassembled part 202 is a non-magnetic plastic part as an engineering common sense.

[0036] The sealed solid bottom 203 of the push handle 2 cooperates with the bottom 101 of the body 1, and when the key works, the sealed solid bottom 203 of the push handle 2 contacts and collides with the bottom 101 of the body 1, thereby providing feedback sound of the key.

[0037] In the embodiment, the body 1 is composed of a base 102 and a cover 103, and is made of non-magnetic material such as ABS plastic or polycarbonate, thereby avoiding magnetic interference. The base 102 of the body 1 cooperates with the cover 103 to form a cavity 105 for accommodating and mounting the push handle 2.

[0038] More specifically, a vertical linear guide groove 106 is arranged on the body 1, and a guide block 204 is arranged on the upper side of the main part 201 of the push handle 2 and cooperates with the linear guide groove 106, thereby realizing the guidance of the push handle 2 in the vertical direction.

[0039] More specifically, in the embodiment, the push handle 2 is connected with the base 102 through at least one elastic element 104, and the push handle 2 is reset after descending through the elastic element 104.

[0040] Preferably, the elastic element 104 is a spiral spring, and the spiral spring has the advantages of stable elastic force, long service life and good reset effect, and the spring material can be selected from steel or stainless steel, thereby ensuring that the push handle 2 can maintain good reset performance in long-term use and prolong the service life of the key.

[0041] More specifically, in the embodiment, the main part 201 of the push handle 2 is connected with the disassembled part 202 through insertion, thereby ensuring the stability of the push handle 2 in the vertical direction.

[0042] In this embodiment, the top end of the disassembled part 202 is provided with a mounting groove 205, and the bottom of the mounting groove 205 is close to the sealed bottom 203 of the press handle 2. The magnetic column 3 is inserted into and fixed in the mounting groove 205 from the top end of the disassembled part 202, which simplifies the installation process of the magnetic column 3 and ensures the stability of the magnetic column 3 in the key.

[0043] In more detail, the material of the disassembled 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 tone and volume when hitting, which can be customized according to user 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 alternative technical solution, the bottom end of the disassembled part 202 is provided with a plastic impact block (not shown in the figure) for tone control. Different plastic materials and designs can be selected to produce different impact sounds, making the product more flexible.

[0045] In this embodiment, the magnetic column preferably uses high-strength magnet materials such as neodymium iron boron magnets (NdFeB) to provide stable magnetic force. The magnetic column is matched with the Hall inductive device, and the position change of the magnetic column is detected by the Hall inductive device to realize accurate detection of the key operation.

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

[0047] At the same time, the Hall inductive device 4 detects the position change of the magnetic column 3 and generates a corresponding electrical signal, which is transmitted 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 makes the handle 2 quickly reset, and the handle 2 and the magnetic column 3 return to the initial position. The Hall inductive device 4 also detects the position change of the magnetic column 3, ending the detection process of the key operation.

[0048] While exemplary embodiments of the present disclosure have been described, it is to be understood that the exemplary embodiments of the present disclosure are provided by way of illustration only. Therefore, various changes and modifications can be suggested to those skilled in the art without departing from the spirit and scope of the present disclosure. Thus, all changes and modifications are intended to be included within the scope of the present disclosure as defined by the appended claims. The present disclosure is defined by the appended claims and their equivalents.
