[0005] The present application relates to the field of controller technology, and in particular to a knob device, a controller and an electrical device. Background Art

[0006] This section merely provides background information related to the present disclosure and is not necessarily prior art.

[0007] With the continuous advancement of science and technology, electronic products are rapidly being updated and iterated, requiring the use of a variety of controllers. Among these, rotary switches are a common control component, found in products such as home appliances, smart homes, and automotive air conditioning controllers. However, the rotary switches currently used in controllers have a single function: most can only be rotated left or right to adjust parameter values. Some knobs require the use of physical buttons to switch functions, making it impossible to simultaneously control multiple functions.

[0008] Summary of the Invention

[0009] The purpose of this application is to at least solve the problem that the knob switch in the controller cannot realize multiple control functions by rotating and pressing. This purpose is achieved by the following methods:

The knob assembly is provided with a magnet, which is used in conjunction with the magnetic induction element. When the knob assembly is rotated, the magnet rotates relative to the magnetic induction element. At this time, the magnetic field strength of the magnet changes.

[0059] Please refer to Figures 1 to 4. In the first aspect of the present application, a knob device 100 is proposed, which is used for a controller 1000. The controller 1000 has a controller cover 200, and the controller cover 200 is provided with a magnetic induction element 300. The knob device 100 includes a damping member 10, a knob assembly and a first elastic member 30.

[0060] Among them, the damping member 10 is used to be set on the controller cover 200, and the damping member 10 has a first mounting cavity 11; the knob assembly is provided with a magnet 23 for cooperating with the magnetic sensing element 300, the knob assembly is rotatably connected to the damping member 10, and the knob assembly is suitable for moving in a direction close to or away from the magnetic sensing element 300; the first elastic member 30 is arranged in the first mounting cavity 11, and is in contact with and connected to the side of the knob assembly facing the magnetic sensing element 300, and is used to provide an elastic restoring force to the knob assembly after the knob assembly is pressed.

[0061] In this embodiment, the magnetic induction element 300 is illustratively a magnetic induction chip. The controller cover 200 has a mounting hole, the magnetic induction element 300 is arranged corresponding to the mounting hole, and the first mounting cavity 11 of the damping member 10 is arranged corresponding to the mounting hole and is in communication with each other.

[0062] Exemplarily, the damping member 10 is cylindrical.

[0063] For example, a portion of the knob assembly is located on the outer periphery of the damping member 10, and another portion is located within the first mounting cavity 11. The knob assembly can both rotate relative to the damping member 10 and move toward or away from the magnetic sensing chip along the axis of the first mounting cavity 11. It will be appreciated that the portion of the knob assembly located on the outer periphery of the damping member 10 is used to drive the entire knob assembly to rotate, or to drive the entire knob assembly to move along the axis of the first mounting cavity 11 toward the magnetic sensing chip.

[0064] The magnet 23 is a mineral having a magnetic field. Specifically, the magnet 23 is annular, and has an N pole and an S pole distributed circumferentially thereon. The magnet 23 and the first mounting cavity 11 are arranged along the same axis.

[0065] For example, the first elastic member 30 is a spring or a spring sheet, and the number of the first elastic member 30 can be one or more. Furthermore, the spring can be a special-shaped spring or a cylindrical spring.

[0066] According to the knob device 100 provided in the embodiment of the present application, a damping member 10 is provided on the controller cover 200, and the first mounting cavity 11 of the damping member 10 is provided corresponding to the magnetic induction element 300. A knob assembly rotatably connected to the damping member 10 is provided, and the knob assembly is provided with a magnet 23. The magnet 23 is used in conjunction with the magnetic induction element 300. When the knob assembly is rotated, the magnet 23 rotates relative to the magnetic induction element 300. At this time, the magnetic field strength of the magnet 23 changes. The magnetic induction chip senses the change in the magnetic field strength of the magnet 23, and converts the change in the magnetic field strength when the magnet 23 rotates into a first electrical signal and transmits it to the controller, so that the controller controls and adjusts the corresponding parameter information according to the first electrical signal. In addition, when the knob assembly is pressed, it can move along the axis of the first mounting cavity 11 toward the magnetic induction chip. At this time, the magnetic field strength of the magnet 23 changes. The magnetic induction chip senses the change in the magnetic field strength of the magnet 23 and converts the change in the magnetic field strength when the magnet 23 moves toward the magnetic induction chip into a second electrical signal and transmits it to the controller, so that the controller controls and adjusts the corresponding parameter information according to the second electrical signal. Therefore, the knob device 100 can realize multiple control functions when the knob assembly is rotated and pressed. It is not only simple in structure, but also helps to improve the user experience.

[0067] Please refer to Figures 1, 2, 4 and 8. According to some embodiments of the present application, the knob assembly includes a knob housing 21 and a rotating connecting shaft 22. The knob housing 21 is covered on the outer peripheral side of the damping member 10, and a second mounting cavity 213 is provided on the side of the knob housing 21 facing the damping member 10. One end of the rotating connecting shaft 22 is provided in the second mounting cavity 213, and the other end is used to be installed in the first mounting cavity 11 and is rotatably connected to the damping member 10; wherein, the magnet 23 is provided on the rotating connecting shaft 22.

[0068] In this embodiment, the knob housing 21 is adapted to the shape of the damping member 10, and the circumferential dimension of the knob housing 21 is slightly larger than the circumferential dimension of the damping member 10. The second mounting cavity 213 of the knob housing 21 has an opening, which is set toward the damping member 10, so that the knob housing 21 can cover the outer peripheral side of the damping member 10.

[0069] Specifically, the first installation cavity 11 of the damping member 10 also has an opening on a side facing the knob assembly, and the rotary connection shaft 22 and the knob housing 21 are arranged along the same axis.

[0070] By disposing a rotary connecting shaft 22 within the second mounting cavity 213 of the knob housing 21 and rotatably connecting the rotary connecting shaft 22 to the damping member 10, rotating the knob housing 21 can drive the rotary connecting shaft 22 to rotate relative to the damping member 10, and thus drive the magnet 23 to rotate relative to the damping member 10, thereby changing the magnetic field strength of the magnet 23. Furthermore, when the knob housing 21 is pressed, it can also drive the rotary connecting shaft 22 and the magnet 23 mounted on the rotary connecting shaft 22 to move toward the magnetic sensing chip, thereby also changing the magnetic field strength of the magnet 23.

[0071] Please refer to FIG. 7 . According to some embodiments of the present application, a limiting groove 221 is provided on the side of the rotating connecting shaft 22 facing the first installation cavity 11 , and the magnet 23 is disposed in the limiting groove 221 .

[0072] In this embodiment, for example, the size of the limiting groove 221 is adapted to that of the magnet 23 , and the magnet 23 is tightly fitted and connected to the limiting groove 221 , thereby helping to improve the reliability and stability of the installation and fixation of the magnet 23 .

[0073] Referring to FIG. 7 , according to some embodiments of the present application, a magnet fixing buckle 224 is provided on the side wall of the limiting groove 221 . The magnet fixing buckle 224 is used to abut against the side of the magnet 23 facing the magnetic sensing element 300 .

[0074] In this embodiment, it can be understood that the bottom wall of the limiting groove 221 faces the magnetic induction element 300, the magnet fixing buckle 224 is arranged on the side wall of the limiting groove 221, and there is an installation gap between the magnet fixing buckle 224 and the bottom wall surface of the limiting groove 221, and the magnet 23 is fixed between the magnet fixing buckle 224 and the bottom wall of the limiting groove 221.

[0075] Please refer to Figures 1, 4, 5, 6 and 7. According to some embodiments of the present application, the rotating connecting shaft 22 is further provided with a mounting groove 222, which is arranged on the side of the limiting groove 221 away from the magnetic sensing element 300 and is connected to the limiting groove 221; the knob assembly also includes a rotating guide buckle 24 and a second elastic member 40, the rotating guide buckle 24 is arranged in the mounting groove 222, and is suitable for moving along the radial direction of the rotating connecting shaft 22, and the rotating guide buckle 24 is provided with a boss 241 on the side of the inner wall surface facing the first mounting cavity 11, the second elastic member 40 is arranged in the mounting groove 222, and abuts against the side of the rotating guide buckle 24 away from the boss 241; wherein, the inner wall surface of the first mounting cavity 11 is provided with a plurality of damping grooves 111, and the plurality of damping grooves 111 are arranged at intervals along the circumference of the first mounting cavity 11, and the boss 241 is suitable for plugging and mating with any damping groove 111.

[0076] In this embodiment, the second elastic member 40 is illustratively an elastic member such as a spring or a spring sheet. One end of the second elastic member 40 abuts against the wall of the mounting groove 222, and the other end abuts against the side of the rotating guide buckle 24 facing away from the boss 241. It is understood that when the knob assembly rotates, that is, when the boss 241 moves from one damping groove 111 to the other damping groove 111, the second elastic member 40 is compressed, thereby allowing the boss 241 to disengage from the previous damping groove 111. When the boss 241 moves to the corresponding position of the other damping groove 111, the second elastic member 40 releases its elastic potential energy and drives the boss 241 to be inserted into the other damping groove 111.

[0077] For example, the damping member 10 and the rotary guide buckle 24 can be made of synthetic plastic (such as polyoxymethylene plastic) or polycarbonate, or a thermoplastic resin and glass fiber composite material. Thus, when the user uses the rotary guide buckle 24 and the damping member 10 made of the aforementioned hard plastic or composite material to adjust the gear position in steps using the knob device 100, that is, when the knob assembly is driven to rotate, the boss 241 can impact each damping groove 111 under the drive of the second elastic member 40, and emit a light and crisp collision sound, allowing the user to clearly feel the feedback brought about by the gear position change, and is less likely to cause misoperation.

[0078] By setting a damping groove 111 on the inner surface of the first mounting cavity 11 of the damping member 10 and setting a rotatable knob assembly in the first mounting cavity 11, the rotating guide buckle 24 of the knob assembly has a boss 241 protruding toward the inner wall surface of the first mounting cavity 11, the boss 241 is used to plug and cooperate with the damping groove 111 and can be inserted into any damping groove 111. In this way, when the user drives the knob assembly to rotate relative to the first mounting cavity 11, the boss 241 moves from one of the damping grooves 111 to another damping groove 111 adjacent to it, which can provide the user with a damping feeling, so that the user can know the level of rotation of the knob assembly without using glasses to observe the rotation angle of the knob, so as to grasp the size of the control gear of the knob device 100, thereby improving the user experience.

[0079] Please refer to FIG. 5 . According to some embodiments of the present application, a guide column 242 is provided on the side of the rotating guide buckle 24 facing away from the boss 241 , and at least a portion of the second elastic member 40 is sleeved on the outer peripheral side of the guide column 242 .

[0080] In this embodiment, a guide column 242 is provided on the side of the rotating guide buckle 24 away from the boss 241, and the second elastic member 40 is sleeved on the outer peripheral side of the guide column 242, so that the guide column 242 can play a guiding role, so that the second elastic member 40 can be compressed along its length direction, thereby improving the stability and reliability of the elastic member driving the boss 241 of the rotating guide buckle 24 to move.

[0081] Please refer to Figure 7. According to some embodiments of the present application, the rotating connecting shaft 22 is provided with a mounting notch 223. The mounting notch 223 is connected to the mounting groove 222 and is adapted to the size of the boss 241. The boss 241 protrudes out of the mounting notch 223.

[0082] In this embodiment, when the rotating guide buckle 24 is installed in the mounting groove 222, the boss 241 can protrude from the mounting notch 223 so that it can abut against the inner wall surface of the first mounting cavity 11 under the drive of the second elastic member 40, so that during the rotation of the rotating connecting shaft 22, the boss 241 can move from one damping groove 111 to another damping groove 111 and emit a collision tactile sensation.

[0083] Please refer to FIG. 6 . According to some embodiments of the present application, adjacent damping grooves 111 are transitionally connected via protrusions 112 , and the surface of the protrusions 112 is an arc-shaped convex surface or a flat surface.

[0084] In this embodiment, the protrusion 112 is connected between two adjacent damping grooves 111 and protrudes toward the center of the first mounting cavity 11, acting as a transition connection, so that when the knob assembly is driven to rotate, the boss 241 moves from one damping groove 111 to another damping groove 111, thereby improving the smoothness of the rotation of the knob assembly.

[0085] Specifically, the surface of the protrusion 112 is an arc-shaped convex surface protruding toward the center of the first installation cavity 11 , thereby facilitating contact movement of the boss 241 along the surface of the protrusion 112 , and helping to improve the stability of the movement of the boss 241 .

[0086] According to some embodiments of the present application, the bottom wall surface of the damping groove 111 is an arc-shaped concave surface or a flat surface.

[0087] In this embodiment, it is understood that when the protrusion 112 is an arcuate convex surface protruding toward the center of the first mounting cavity 11, the bottom wall surface of the damping groove 111 can be a flat surface. Of course, the bottom wall surface of the damping groove 111 can also be an arcuate concave surface. Since both can achieve the purpose of this application, they are all within the scope of protection of this application.

[0088] According to some embodiments of the present application, along the radial direction of the rotary connection shaft 22 , the maximum distance between the damping groove 111 and the protrusion 112 is set in the range of 0.1 mm to 0.5 mm.

[0089] In this embodiment, that is, along the radial direction of the rotating connecting shaft 22, the distance between the top end surface of the protrusion 112 and the bottom wall surface of the damping groove 111 is set in the range of 0.1mm to 0.5mm, so that the protruding distance of the protrusion 112 is shorter, which helps to reduce the space occupied by the protrusion 112 in the first mounting cavity 11.

[0090] Please refer to Figure 6. According to some embodiments of the present application, the line between the center of the first installation cavity 11 and the centers of the two adjacent damping grooves 111 forms a first line segment and a second line segment, respectively, and the angle between the first line segment and the second line segment is set in the range of 15° to 50°.

[0091] In this embodiment, it can be understood that the line connecting the center of one of the adjacent damping grooves 111 and the center of the first mounting cavity 11 is the first line segment, and the line connecting the center of the other one and the center of the first mounting cavity 11 is the second line segment. The angle β between the first line segment and the second line segment is set in the range of 15° to 50°, so that the number of levels can be set to at least 24 levels. Every time the user rotates at least 15°, one level of adjustment can be achieved, which effectively improves the user experience.

[0092] According to some embodiments of the present application, along a direction perpendicular to the axis of the rotating connecting shaft 22 , the cross-sectional shape of the first installation cavity 11 is annular, and the outer surface of the rotating connecting shaft 22 is adapted to the shape of the first installation cavity 11 .

[0093] In this embodiment, the cross-sectional shape of the first mounting cavity 11 is annular, the shape of the outer surface of the rotating connecting shaft 22 is also annular, and there is a gap between the outer surface of the rotating connecting shaft 22 and the inner surface of the first mounting cavity 11, thereby reducing the wear or jamming caused by the contact between the rotating connecting shaft 22 and the inner wall surface of the first mounting cavity 11, which helps to improve the service life of the product.
