Description

Technical Field

[0001] This utility model relates to the field of push button switch technology, and in particular to a magnetic shaft push button switch. Background Technology

[0002] The push-button switch with a magnetic shaft as its main body has a base mounted on a PCB board, a housing connected to the base, and a shaft and magnet installed inside the housing and base. When in use, pressing the shaft causes the magnet to descend with the shaft, and the signal is switched after the Hall element senses the magnetic field of the magnet. When the shaft moves up to reset, the magnet moves up with the shaft, and the Hall element senses the magnetic field of the magnet again and switches the signal again.

[0003] However, when pressed, the shaft and magnet slide in contact with the inner surface of the base, and the button switch hardly makes a sound when the shaft and magnet are pressed down, resulting in weak feedback.

[0004] Therefore, existing technologies need to be improved and enhanced. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a magnetic shaft button switch that produces a crisp sound and has a strong tactile feedback when pressed.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A magnetic shaft push-button switch includes a base, a top cover, a button, a spring, and a magnet. The top cover is fastened to the base, and the top cover and the base form a receiving cavity. The button and the spring are both installed in the receiving cavity. The button extends downward with a second positioning post, which is correspondingly disposed in a guide hole of a first positioning post on the base. The second positioning post is embedded in the guide hole and can move up and down along the guide hole. The spring is disposed between the button and the base. One end of the spring is sleeved with the second positioning post, and the other end is sleeved with the first positioning post. The magnet is embedded in the end of the second positioning post facing the base, and the magnet protrudes from the end face of the second positioning post facing the base. When pressed, the magnet can strike the bottom surface of the guide hole.

[0008] Preferably, the bottom surface of the guide hole of the base is closed and flat.

[0009] Preferably, the bottom surface of the guide hole of the base is provided with a racetrack-shaped through hole corresponding to the magnet.

[0010] Preferably, the outer circumferential surface of the second positioning post is provided with a plurality of raised ribs along the axial direction, and the plurality of raised ribs are in contact with the inner wall surface of the guide hole.

[0011] Preferably, there are four ribs.

[0012] Preferably, the end of the second positioning post facing the base has a mounting groove, the magnet is installed in the mounting groove, and the shape of the mounting groove is adapted to the shape of the magnet.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Due to the above structural design, since the magnet protrudes from the end face of the second positioning post facing the base, when pressed, the magnet collides with the base to produce sound. The sound source vibrates in the cavity and forms an echo, thus producing a relatively crisp sound in the cavity. This makes the button switch sound crisp when pressed, effectively increasing the feedback of the button switch. Attached Figure Description

[0025] The embodiments described with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application 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, and therefore should not be construed as limiting this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0026] In the description of this application, "several" or "more than" means two or more, unless otherwise explicitly specified. In this application, unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0027] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature. Example 1:

[0028] like Figure 1-4As shown, this embodiment of a magnetic shaft push-button switch includes a base 100, a top cover 200, a button 300, a spring 400, and a magnet 500. The top cover 200 is fastened to the base 100, and the top cover 200 and the base 100 form a receiving cavity. The button 300 and the spring 400 are both installed in the receiving cavity. The button 300 extends downward with a second positioning post 301, which is correspondingly disposed in the guide hole 102 of the first positioning post 101 on the base 100. The second positioning post 301 is embedded in the guide hole 102 and can move up and down along the guide hole 102. The spring 400 is disposed between the button 300 and the base 100. One end of the spring 400 is sleeved with the second positioning post 301, and the other end is sleeved with the first positioning post 101. The second positioning post 301 faces the... The magnet 500 is embedded at the end of the base 100. The magnet 500 protrudes from the end face of the second positioning post 301 facing the base 100. When pressed, the magnet 500 can strike the bottom surface of the guide hole 102. The bottom surface of the guide hole 102 of the base 100 is closed and flat. With the above structural design, when in use, this application is mounted on a PCB board. A Hall element is mounted on the PCB board. When pressed, the button 300 moves down, causing the magnet 500 to move down. After the Hall element senses the magnetic field of the magnet 500, it switches the signal. At the same time, the bottom end of the magnet 500 abuts against the bottom surface of the guide hole 102 of the base 100. The magnet and the bottom surface collide and make a sound. When the pressing pressure is removed, the button 300 returns to its original position under the action of the spring 400. The Hall element senses the magnetic field again as the magnet 500 moves up with the button 300 and switches the signal again. Since the button 300 and magnet 500 are located inside the receiving cavity, when magnet 500 collides with the bottom surface, the sound source vibrates inside the receiving cavity and forms an echo, thus producing a relatively crisp sound inside the receiving cavity. This makes the button switch sound crisp when pressed, effectively increasing the feedback of the button switch.

[0029] In a preferred embodiment, the outer circumferential surface of the second positioning post 301 is provided with four ribs 302 along the axial direction. The four ribs 302 contact the inner wall surface of the guide hole 102. Through the above structural design, since the second positioning post of the button contacts the inner wall surface of the guide hole of the first positioning post of the base through the four ribs on its outer circumferential surface, the contact area between the second positioning post and the first positioning post is reduced, thereby effectively reducing the friction between the two. When frequent pressing operations are required, the user does not need to apply more force when pressing or releasing the switch, making the operation convenient. At the same time, the lower friction makes the button feel lighter and more sensitive, improving the user experience. Under the action of low friction for a long time, the contact surface between the button and the base wears slowly. In addition, with low friction, the button can quickly reset, making the switch response speed faster, thereby improving the working efficiency or performance of the switch.

[0030] Specifically, the second positioning post 301 has a mounting groove 303 at its end facing the base 100, the magnet 500 is installed in the mounting groove 303, and the shape of the mounting groove 303 is adapted to the shape of the magnet 500, so as to facilitate the installation of the magnet 500 on the second positioning post. Example 2:

[0031] like Figure 5 and Figure 6 As shown, this embodiment differs from Embodiment 1 in that the bottom surface of the guide hole 102 of the base 100, corresponding to the magnet 500, has a racetrack-shaped through hole 103. The width of the racetrack-shaped through hole 103 is smaller than the diameter of the magnet 500. When pressed, the magnet 500 can strike the bottom surface of the guide hole 102, i.e., the through hole 103, thereby producing different sounds. Other similarities will not be repeated here.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents. The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered within the scope of protection of the present invention.
