[0034] The following description provides specific application scenarios and requirements for this specification, intended to enable those skilled in the art to make and use the contents of this specification. Various partial modifications to the disclosed embodiments will be apparent to those skilled in the art, and the general principles defined herein can be applied to other embodiments and applications without departing from the spirit and scope of this specification. Therefore, this specification is not limited to the embodiments shown, but rather to the widest scope consistent with the claims.

[0035] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "longitudinal", "lateral", "radial", "length", "width", "thickness", "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are mainly for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element or component to have a specific orientation, or to be constructed and operated in a specific orientation.

[0036] It should be noted that the terms "first," "second," and similar words do not indicate any order, quantity, or importance, but are only used to distinguish different components and should not be construed as limiting the embodiments of this application.

[0037] It should be noted that the terms "installation," "setup," "equipped with," "connection," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral structures; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium, or internal connections between two devices, components, or parts.

[0038] It should be noted that the terms "in some embodiments," "exemplarily," and "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "in some embodiments," "exemplarily," or "for example" should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "in some embodiments," "exemplarily," and "for example" is intended to present the relevant concepts in a specific manner, meaning that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of this application.

[0039] Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] Regarding the accompanying drawings of this application, it should be clearly understood that the drawings are for illustrative and descriptive purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not necessarily drawn to scale.

[0041] like Figures 1 to 3 As shown in the figure, this specification provides a magnetic reset structure for an electronic switch, including a housing 1, an operating member 2, a first magnetic member 3, a second magnetic member 4, and a third magnetic member 5. The operating member 2 can be pressed down and pulled up relative to the housing 1. The first magnetic member 3 and the operating member 2 are slidably disposed in the housing 1. The second magnetic member 4 is disposed on the moving path of the first magnetic member 3, connected to the operating member 2, and moves with it, and is magnetically connected to the upper side of the first magnetic member 3. The third magnetic member 5 is disposed on the moving path of the first magnetic member 3, and is in a fixed state, generally fixed to the housing 1, and is magnetically connected to the first magnetic member 3. On the upper side of a magnetic component 3, it is configured such that when the operating component 2 is pressed down, the first magnetic component 3 moves with the second magnetic component 4 and separates from the third magnetic component 5. After separation, it can be reset by the magnetic attraction between the first magnetic component 3 and the third magnetic component 5. When the operating component 2 is lifted, the second magnetic component 4 moves with the operating component 2 and separates from the first magnetic component 3. After separation, it can be reset by the magnetic attraction between the first magnetic component 3 and the second magnetic component 4. The reset is achieved by the magnetic attraction, so that the electronic switch can realize the pressing and lifting functions at the same time. It has a simple structure, stable function, long service life and low operating noise.

[0042] It should be understood that magnetic components are generally magnetic materials or materials that are attracted by magnets. Magnetic materials refer to materials that have magnetism and can actively generate magnetic fields. They usually include permanent magnets, electromagnets, soft magnets, etc. Materials that are attracted by magnets refer to materials that can be attracted by magnetic materials. They usually include iron, steel, iron alloys, etc.

[0043] Therefore, the material settings for the first magnetic component 3, the second magnetic component 4, and the third magnetic component 5 can be as follows:

[0044] For example, the first magnetic component 3 is made of magnetic material, and the second magnetic component 4 and the third magnetic component 5 are made of magnetically attracted material. This solution is generally preferred because it only requires one magnet, which reduces the cost of the product.

[0045] The first magnetic component 3 has an adhesive layer 8 on its upper surface, and the second magnetic component 4 is bonded to the third magnetic component 5 to ensure that the pressing and lifting functions are stably realized.

[0046] For example, the first magnetic element 3 is made of a magnetically attracted material, and the second magnetic element 4 and the third magnetic element 5 are made of magnetically attracted materials. This solution makes the pressing and lifting functions more reliable.

[0047] For example, the first magnetic element 3, the second magnetic element 4 and the third magnetic element 5 are all made of magnetic material.

[0048] In some embodiments, the first magnetic element 3, the second magnetic element 4, and the third magnetic element 5 are all ring-shaped. The inner and outer rings of the upper surface of the first magnetic element 3 are magnetically connected to the second magnetic element 4 and magnetically connected to the third magnetic element 5, respectively. This arrangement ensures that the ring structure generates a uniform magnetic force around the circumference, which can improve the stability of the operating element 2 when it is reset.

[0049] The first magnetic component 3 is provided with at least one first rotation positioning part 6, and the housing 1 is provided with a second rotation positioning part 7 corresponding to the first rotation positioning part 6, so as to prevent the first magnetic component 3 from rotating and improve its stability when pressing down and lifting.

[0050] It is understandable that the rotary positioning part can be implemented using a matching positioning groove and positioning block structure.

[0051] For example, such as Figure 2 and Figure 3 As shown, the first magnetic component 3 is provided with a plurality of positioning grooves in the circumferential direction, and the positioning grooves are provided through the thickness direction of the first magnetic component 3. The housing 1 is provided with a corresponding positioning block.

[0052] like Figures 4 to 7 As shown in the specification, this specification also provides a rotary switch, including the magnetic reset structure of the electronic switch, a circuit board 9, a rotating block 12, a bracket 13, a track body 14, and a base 15. The circuit board 9 is provided with a first micro switch 10 and a second micro switch 11. The rotating block 12 includes a first trigger end 120 corresponding to the first micro switch 10, a second trigger end 121 corresponding to the second micro switch 11, a first hinge part 122 connected to the operating member 2, and a second hinge part 123 connected to the housing 1. The second hinge part 123 is located in the middle of the rotating block 12. The operating member 2 is provided with a third hinge part 200 corresponding to the first hinge part 122, and the housing 1 is provided with a fourth hinge part 100 corresponding to the second hinge part 123. When the operating member 2 is pressed down, the first trigger end 120 presses down to trigger the first micro switch 10. When the operating member 2 is pulled up, the second trigger end 121 presses down to trigger the second micro switch 11. With this configuration, the operating element 2 can output different functions when pressed down and pulled up, thus enriching the functions of the switch.

[0053] Specifically, the bracket 13 slides up and down along the housing 1, the track 14 is rotatably mounted on the bracket 13, the operating element 2 is a knob connected to and driving the track 14 to rotate, the base 15 is connected to the housing 1, the third magnetic element 5 is fixed between the housing 1 and the base 15, the third hinge 200 is disposed on the bracket 13, and the fourth hinge 100 is disposed on the base 15. It should be understood that the structure for implementing the rotation adjustment function in a knob switch only needs to refer to the corresponding knob switches in the prior art, and will not be described in detail here.

[0054] Among them, the first hinge part 122 and the third hinge part 200 are respectively a hinge hole and a hinge shaft, and the second hinge part 123 and the fourth hinge part 100 are respectively a hinge hole and a hinge shaft.

[0055] For example, the first hinge portion 122 is a hinge shaft disposed on both sides of one end of the rotating pressure block 12, the third hinge portion 200 is a hinge hole correspondingly disposed on the bracket 13, the second hinge portion 123 is a hinge hole disposed on both sides of the middle part of the rotating pressure block 12, and the fourth hinge portion 100 is a hinge shaft correspondingly disposed on the base 15.

[0056] Optionally, at least one of the hinge holes is an oblong hole, such as... Figure 5 As shown, the third hinge portion 200 uses an oblong hole. This design reduces the requirements for manufacturing and assembly precision of the rotating pressure block 12.

[0057] Furthermore, the first trigger end 120 and the second trigger end 121 are provided with arc-shaped trigger surfaces 124.

[0058] Furthermore, the hinge shaft is provided with a guide slope 125 that facilitates its assembly.

[0059] It should be understood that the magnetic reset structure of the electronic switch is not limited to rotary switches, but should be applicable to other electronic switches that require both pressing and lifting functions.

[0060] In summary, after reading this detailed disclosure, those skilled in the art will understand that the foregoing detailed disclosure is presented by way of example only and is not restrictive. Although not explicitly stated herein, those skilled in the art will understand that the requirements of this application encompass various reasonable changes, improvements, and modifications to the embodiments. These changes, improvements, and modifications are intended to be made by this application and are within the spirit and scope of the exemplary embodiments of this application.

[0061] Furthermore, it should be understood that in the foregoing description of the embodiments of this application, various features are combined in a single embodiment, drawing, or description for the purpose of simplifying the understanding of a feature. However, this does not mean that the combination of these features is necessary, and those skilled in the art may readily identify some of the devices as separate embodiments when reading this application. That is, the embodiments in this application can also be understood as an integration of multiple sub-embodiments. It is also valid when each sub-embodiment contains fewer than all the features of a single foregoing disclosed embodiment.

[0062] Finally, it should be understood that the embodiments disclosed herein are illustrative of the principles of the embodiments of this application. Other modified embodiments are also within the scope of this application. Therefore, the embodiments disclosed herein are merely examples and not limitations. Those skilled in the art can adopt alternative configurations to implement the applications in this application based on the embodiments in this application. Therefore, the embodiments of this application are not limited to the embodiments precisely described in the application.
