Description

Technical Field

[0001] The present invention relates to the technical field of electronic switches, and in particular to a magnetic reset structure and a knob switch of an electronic switch. Background Art

[0002] Electronic switches are control devices that utilize electronic components to perform on / off functions. They are widely used in automotive electronic systems, such as those controlling lights, air conditioning, and audio systems. Compared to traditional mechanical switches, electronic switches offer advantages such as fast response, low power consumption, and high reliability, effectively enhancing the intelligence of vehicles. A common electronic switch is the rotary switch, which controls circuits through rotation and is commonly used to adjust functions such as volume, air conditioning temperature, and window lifts within the vehicle. Its intuitive operation allows users to make precise adjustments, enhancing the driving experience. The combination of these two in modern vehicles provides drivers with a more convenient and comfortable operating interface, improving overall vehicle functionality and safety.

[0034] The following description provides specific application scenarios and requirements for this specification, with the goal of enabling those skilled in the art to make and use the contents of this specification. Various modifications to the disclosed embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may 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 is intended to be accorded the broadest 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", "transverse", "radial", "length", "width", "thickness", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. These terms are mainly intended to better describe this application and its embodiments, and are not intended to limit the indicated devices, elements or components to 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 understood as limitations on the embodiments of the present application.

[0037] It should be noted that the terms "installed," "set," "provided with," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; or internal communication between two devices, elements, or components.

[0038] It should be noted that the terms "in some embodiments," "exemplarily," "for example," and the like 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 interpreted as being more preferred or advantageous than other embodiments or designs. Specifically, the use of words such as "in some embodiments," "exemplarily," and "for example" is intended to present the relevant concepts in a concrete manner, meaning that the specific features, structures, or characteristics described in conjunction with the embodiment may be included in at least one embodiment of this application.

[0039] For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0040] Regarding the drawings of this application, it should be clearly understood that the drawings are for illustration and description 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, this specification provides a magnetic reset structure of an electronic switch, including a shell 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 realize downward pressing and lifting operations relative to the shell 1. The first magnetic member 3 and the operating member 2 are arranged on the shell 1 for sliding in the same direction. The second magnetic member 4 is arranged on the moving path of the first magnetic member 3, and is connected to the operating member 2 and moves with it. It is magnetically connected to the upper side of the first magnetic member 3. The third magnetic member 5 is arranged on the moving path of the first magnetic member 3, and is in a fixed state, generally fixed on the shell 1. It is magnetically connected to the third magnetic member 5. The upper side of a magnetic part 3 is configured so that when the operating part 2 is pressed down, the first magnetic part 3 moves with the second magnetic part 4 and is separated from the third magnetic part 5. After separation, it can be reset by the magnetic attraction force between the first magnetic part 3 and the third magnetic part 5. When the operating part 2 is pulled up, the second magnetic part 4 moves with the operating part 2 and is separated from the first magnetic part 3. After separation, it can be reset by the magnetic attraction force between the first magnetic part 3 and the second magnetic part 4. Resetting is achieved through magnetic attraction, so that the electronic switch can realize the pressing and pulling functions at the same time, and has a simple structure, stable function, long service life and low operating noise.

[0042] It should be understood that magnetic parts are generally magnetic materials or magnetically attracted materials. Magnetic materials refer to materials with magnetism that can actively generate magnetic fields, usually including: permanent magnets, electromagnets, soft magnets, etc. Magnetically attracted materials refer to materials that can be adsorbed by magnetic materials, usually including: iron, steel, iron-containing alloys, etc.

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

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

[0045] The upper end surface of the first magnetic component 3 is provided with a glue layer 8 and the second magnetic component 4 is bonded to the third magnetic component 5 to ensure that the pressing and pulling functions are stably realized.

[0046] For example, the first magnetic member 3 is made of a magnetically attracted material, and the second magnetic member 4 and the third magnetic member 5 are made of a magnetically attracted material. In this solution, the pressing and pulling functions are more reliable.

[0047] Exemplarily, the first magnetic component 3 , the second magnetic component 4 and the third magnetic component 5 are all made of magnetic attraction materials.

[0048] In some embodiments, the first magnetic member 3, the second magnetic member 4 and the third magnetic member 5 are all ring-shaped, and the inner ring and the outer ring of the upper end surface of the first magnetic member 3 are magnetically connected to the second magnetic member 4, and the other is magnetically connected to the third magnetic member 5. With this arrangement, the ring structure ensures that uniform magnetic attraction is generated around the circle, which can improve the stability of the operating member 2 when it is reset.

[0049] Among them, at least one first rotation positioning portion 6 is provided on the first magnetic member 3, and a second rotation positioning portion 7 is provided on the shell 1 corresponding to the first rotation positioning portion 6, so as to prevent the first magnetic member 3 from rotating and improve its stability when pressing down and pulling.

[0050] It can be understood that the rotation positioning portion can be implemented by using a matching positioning groove and positioning block structure.

[0051] For example, Figure 2 and Figure 3 As shown, a plurality of positioning grooves are circumferentially provided on the first magnetic member 3 , and the positioning grooves are provided through the thickness direction of the first magnetic member 3 , and the housing 1 is correspondingly provided with positioning blocks.

[0052] like Figures 4 to 7 As shown, this specification also provides a knob switch, including the magnetic reset structure of the electronic switch, a circuit board 9, a rotary pressure block 12, a bracket 13, a rail 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 rotary pressure 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 portion 122 connected to the operating member 2 and a second hinge portion 123 connected to the housing 1, the second hinge portion 123 is located in the middle of the rotary pressure block 12, the operating member 2 is provided with a third hinge portion 200 corresponding to the first hinge portion 122, and the housing 1 is provided with a fourth hinge portion 100 corresponding to the second hinge portion 123; when the operating member 2 is pressed down, the first trigger end 120 presses down to trigger the first micro switch 10, and when the operating member 2 is pulled, the second trigger end 121 presses down to trigger the second micro switch 11. With such arrangement, the operating member 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 body 14 is rotatably mounted on the bracket 13, the operating member 2 is a knob connected to the track body 14 and drives its rotation, the base 15 is connected to the housing 1, the third magnetic member 5 is fixed between the housing 1 and the base 15, the third hinge portion 200 is mounted on the bracket 13, and the fourth hinge portion 100 is mounted on the base 15. It should be understood that the structure of the knob switch for implementing the rotation adjustment function can be referred to the corresponding knob switch in the prior art and will not be described in detail here.

[0054] Among them, one of the first hinge part 122 and the third hinge part 200 is a hinge hole and the other is a hinge shaft, and one of the second hinge part 123 and the fourth hinge part 100 is a hinge hole and the other is a hinge shaft.

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

[0056] Optionally, at least one of the hinge holes is a waist-shaped hole, such as Figure 5 As shown, the third hinge portion 200 adopts a waist-shaped hole. Such a configuration and the use of the waist-shaped hole can reduce the requirements of the rotating pressing block 12 on production accuracy and assembly accuracy.

[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 which is beneficial for its assembly.

[0059] It should be understood that the magnetic reset structure of the electronic switch is not limited to being applicable to knob switches, but should be applicable to other electronic switches that require both push-down and pull-up functions.
