[0024] The structural and working principles of the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] like Figures 1-5 As shown, this invention is an adjustable rocker potentiometer, comprising a base 1, a rotating disk 2, a spring 3, a sliding disk 4, a rocker arm 5, an upper rocker arm 6, a lower rocker arm 7, a cover 8, a pinion 9, and a rotary housing 10. The base 1 has a cavity 11, and the rotating disk 2 is rotatably mounted within the cavity 11. An annular convex ring 12 is provided within the cavity 11, and an annular groove 13 is provided at the bottom of the rotating disk 2, with the annular convex ring 12 housed within the annular groove 13. It should be noted that the positions of the annular convex ring and the annular groove can also be interchanged, i.e., an annular groove is provided in the cavity 11, while an annular convex ring is provided at the bottom of the rotating disk 2; the function is equivalent. The annular convex ring 12 and the annular groove 13 respectively have beginning ends 121 and 131 and end ends 122 and 132. 2. The height gradually increases. When the rotating disk 2 rotates, the annular convex ring 12 and the annular groove 13 slide relative to each other, causing the rotating disk 2 to rise or fall. The spring 3 is installed on the rotating disk 2, and the sliding disk 4 is installed on the spring 3. Several guide feet 14 are connected to the side of the cavity 11 of the base 1, and the guide feet 14 slide in cooperation with the side of the sliding disk 4. The cover 8 is installed on the base 1, the rocker arm 5 is installed on the sliding disk 4, and the upper rocker arm 6 and the lower rocker arm 7 are installed sequentially from top to bottom inside the cover 8. The rocker arm 5 passes through the cover 8, the upper rocker arm 6 and the lower rocker arm 7 and is connected to the lower rocker arm 7. The pinion 9 is installed on the base 1, and the rotary housing 10 is rotatably disposed outside the cover 8. The lower end of the rotary housing 10 is provided with an internal gear 103, which meshes with the pinion 9. The rotating disk 2 is provided with an external gear 21, which meshes with the pinion 9.

[0026] The operation force adjusting method of the rocker potentiometer comprises an operation force increasing method and an operation force decreasing method: (1) when the operation force of the rocker 5 needs to be increased, the rotary adjusting shell 10 is rotated clockwise, the inner gear 103 of the rotary adjusting shell 10 drives the pinion 9 to rotate clockwise, the pinion 9 drives the rotating disc 2 to rotate counterclockwise, the tail end of the annular protrusion 12 gradually slides from the tail end of the annular groove 13 to the head end of the annular groove 13, the rotating disc 2 gradually rises in the cavity 11, the spring 3 is compressed upwards by the rotating disc 2, the force of the spring 3 pressing the sliding disc 4 is increased, and thus, in the process of the rocker 5 being operated, a greater operation force is needed to make the sliding disc 4 slide downwards; (2) when the operation force of the rocker 5 needs to be decreased, the rotary adjusting shell 10 is rotated counterclockwise, the inner gear 103 of the rotary adjusting shell 10 drives the pinion 9 to rotate counterclockwise, the pinion 9 drives the rotating disc 2 to rotate clockwise, the tail end of the annular protrusion 12 gradually slides from the head end of the annular groove 13 to the tail end of the annular groove 13, the rotating disc 2 gradually falls in the cavity 11, the spring 3 is released downwards by the rotating disc 2, the force of the spring 3 pressing the sliding disc 4 is decreased, and thus, in the process of the rocker 5 being operated, a smaller operation force can make the sliding disc 4 slide downwards. The operation force or the hand feeling force of the rocker can be adjusted by manually rotating the rotary adjusting shell, the component structure for adjusting the operation force or the hand feeling force of the rocker is simple, the cost is low, the use is convenient, the stability is good, and the occupied space is small.

[0027] As shown in Figure 3 , 4 , 6, 7, the head end 121 of the annular protrusion 12 is close to the tail end 122 of the annular protrusion 12, and the head end 131 of the annular groove 13 is close to the tail end 132 of the annular groove 13. In the process of increasing the operation force of the rocker 5, the tail end of the annular protrusion 12 gradually slides from the tail end of the annular groove 13 to the head end of the annular groove 13, when the tail end of the annular protrusion 12 reaches the head end position of the annular groove 13, the rotating disc 2 reaches the highest position, and at this time, the operation force of the rocker 5 is the largest; when the rotary adjusting shell 10 is continuously rotated clockwise, because the head end 121 of the annular protrusion 12 is close to the tail end 122 of the annular protrusion 12, and the head end 131 of the annular groove 13 is close to the tail end 132 of the annular groove 13, the tail end of the annular protrusion 12 will directly jump into the tail end 132 of the annular groove 13 from the head end 131 of the annular groove 13, so that the rotating disc 2 instantaneously returns to the lowest position, and at this time, the operation force of the rocker 5 is the smallest. The structure of the present application can avoid the problem that the rotary adjusting shell 10 is continuously rotated by the user to damage the rocker potentiometer in the process of increasing the operation force of the rocker 5.

Similarly, the diameter of one annular groove 13 is smaller than the diameter of the other annular groove 13, and the angle between the beginning 131 and the center of the two annular grooves 13 is 180 degrees, as is the angle between the end 132 and the center of the two annular grooves 13.

The convex ring 104 ensures that the tuning housing 10 and the cover 8 maintain a sufficient overall distance, and at the same time, the convex ring 104 can rotate stably outside the lower end of the cover 8.

[0032] like Figures 1-5 and Figure 8As shown, the rocker potentiometer with adjustable operating force further comprises an FPC flexible circuit board 16 mounted on the base 1, and a first magnetic induction chip 161 and a second magnetic induction chip 162 are welded on the FPC flexible circuit board 16; one end of the upper rocker arm 6 is provided with a first permanent magnet 61, the first permanent magnet 61 is opposite to the first magnetic induction chip 161 in position and cooperates with each other through electromagnetic induction; one end of the lower rocker arm 7 is provided with a second permanent magnet 71, the second permanent magnet 71 is opposite to the second magnetic induction chip 162 in position and cooperates with each other through electromagnetic induction.
