[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0033] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0034] Please refer to Figures 1 to 4The utility model proposes a key structure 1000, including a circuit board 1, a rotating component 2 and a toggle component 3, the rotating component 2 including an encoder 21 and a rotating member 22, the encoder 21 including an encoder inner ring 211 and an encoder outer ring 212, the encoder 21 is arranged on the circuit board 1 and is electrically connected to the circuit board 1; the encoder outer ring 212 is rotatably sleeved on the encoder inner ring 211; the rotating member 22 is sleeved on the encoder outer ring 212; the toggle component 3 includes a toggle switch 31, the toggle switch 31 is arranged on the circuit board 1 and is electrically connected to the circuit board 1; the toggle switch 31 is movably penetrated through the encoder inner ring 211 and the rotating member 22, and one end of the toggle switch 31 away from the circuit board 1 is exposed from the encoder inner ring 211.

[0035] In the technical solution of the present utility model, when the user toggles the toggle switch 31 to switch to the on state, the toggle switch 31 is connected to the circuit board 1, and the circuit board 1 performs a corresponding on operation after receiving the on signal of the toggle switch 31; when the user toggles the toggle switch 31 to switch to the off state, the toggle switch 31 is disconnected from the circuit board 1, and the circuit board 1 performs a corresponding off operation after receiving the disconnect signal of the toggle assembly 3; the user rotates the rotating member 22, and the rotating member 22 drives the encoder outer ring 212 to rotate. At this time, the encoder inner ring 211 detects the rotation angle and direction of the encoder outer ring 212, and converts the rotation information into an electrical signal and outputs it to the circuit board 1, thereby performing a corresponding adjustment operation; the button structure 1000 integrates the rotation adjustment and the toggle adjustment into one, realizes the independence of the rotation and toggle functions, has a simple and reliable structure, and can save the space occupied by the button.

[0036] The encoder inner ring 211 is fixedly arranged on the circuit board 1, and the encoder outer ring 212 is rotatably connected to the encoder inner ring 211. The encoder outer ring 212 and the encoder inner ring 211 can be rotatably connected through a bearing or a bearing kit. This connection method allows the encoder outer ring 212 and the encoder inner ring 211 to rotate relative to each other and maintain a stable mechanical connection; the encoder inner ring 211 can be a photoelectric encoder or a magnetic encoder, which is used to measure the rotation angle or position of the encoder outer ring 211. The photoelectric encoder detects the rotation position of the encoder outer ring 211 by pairing a light source and a photosensitive device. When the grating or encoding disk on the encoder outer ring 211 is in contact with the encoder, the encoder outer ring 211 is rotated. When the light between the light source and the photosensitive device on the encoder inner ring 211 is blocked or transmitted, the photosensitive device will generate corresponding electrical signals. After processing, these electrical signals can be used to obtain the rotation angle or position information of the encoder outer ring 211; the magnetic encoder uses the magnetic field to detect the position of the encoder outer ring 211. There is an interaction between the magnetic sensor on the encoder outer ring 211 and the magnetic field encoder on the encoder inner ring 211. When the encoder outer ring 211 rotates, the magnetic field encoder will generate corresponding magnetic field changes. The magnetic sensor will sense these changes and convert them into electrical signals. By processing these electrical signals, the rotation angle or position information of the encoder outer ring 211 can be obtained.

[0037] The connection between the encoder 21 and the circuit board 1 can be achieved by setting pins on the encoder 21 and welding them to the circuit board 1, or by setting a socket on the encoder 21, setting an interface on the circuit board 1, and inserting the socket on the encoder 21 into the corresponding interface on the circuit board 1. The utility model does not limit this. The connection between the toggle switch 31 and the circuit board 1 can be achieved by setting pins on the toggle switch 31 and welding them to the circuit board 1, or by setting a socket on the toggle switch 31, setting an interface on the circuit board 1, and inserting the socket on the toggle switch 31 into the corresponding interface on the circuit board 1. The utility model does not limit this.

[0038] The toggle switch 31 generally has an on and off state, but is not limited thereto. In the technical solution of the present utility model, the toggle switch 31 can be used to adjust different functions or modes. For example, some devices may have different speed gears, and the toggle switch 31 can be used to switch different speeds. Alternatively, some devices may have different operating modes, such as normal mode and energy-saving mode. The toggle switch 31 can be used to switch between different modes, and can provide users with a variety of control options to meet different needs of users.
