The damping assembly 4 includes a damping member 41 and an elastic member 42. One end of the elastic member 42 is connected to the cavity wall of the telescopic cavity 211, and the other end is sleeved with the damping member 41, so that the damping member 41 can be telescopically arranged in the telescopic cavity 211, and the damping member 41 can contact with the tooth grid groove or the median groove 32. The dial wheel 1 is turned to drive the rotating seat 2 to rotate on the mounting seat 3, thereby causing the damping member 41 to slide on the tooth grid groove or the middle groove 32. The damping member 41 is telescopically arranged in the telescopic cavity 211 through the elastic member 42, and the groove depths of each tooth grid groove are equal, so that the contact between the damping member 41 and each tooth grid groove or the middle groove 32 is stable, and it is ensured that when the damping member 41 slides on each tooth grid groove, the tooth feeling damping is uniform, and when the dial wheel 1 is turned, the tooth feeling of the damping member 41 is clear one by one; the groove depth of the middle groove 32 is greater than the groove depth of each tooth grid groove, so that when the damping member 41 slides on the middle groove 32, there is a clear sense of movement, which meets the user's control needs and improves the user's control experience.

[0040] Specifically, the elastic member 42 may be a spring.

[0041] like Figures 1-4 As shown, the rotary potentiometer further includes a contact assembly 6 , which includes a circuit board 61 and a contact piece 62 . The contact piece 62 is connected to the rotating seat 2 . The circuit board 61 is fixed on the mounting seat 3 , and the contact piece 62 is in contact with the circuit board 61 .

[0042] Furthermore, the contact assembly 6 also includes a contact seat 63, which is coaxially connected to the rotating seat 2, and at least one contact piece 62 is provided on the contact seat 63. The dial wheel 1 is turned to drive the rotating seat 2 to rotate on the mounting seat 3, so that the damping member 41 slides on the tooth grid groove or the middle groove 32. At the same time, the rotating seat 2 drives the contact seat 63 and the contact piece 62 to rotate, so that the contact piece 62 contacts different positions of the circuit board 61 to adjust the zoom or magnification of the camera, or adjust the rotation angle of the camera, etc. Of course, the contact piece 62 contacts different positions of the circuit board 61, which can also be used to implement control commands for other requirements.

[0043] In this embodiment, the number of the contact pieces 62 is four. One contact piece 62 is arranged on the side of the contact seat 63 close to the dial wheel 1 , and three contact pieces 62 are arranged on the side of the contact seat 63 away from the dial wheel 1 .

[0044] Furthermore, the dial potentiometer also includes a first fastener 7, the dial 1 includes a dial body 11 and a first mounting portion 12, the first mounting portion 12 is protruded on the dial body 11, the rotating base 2 includes a second mounting portion 23, and the first mounting portion 12 and the second mounting portion 23 are fixedly connected by the first fastener 7.

[0045] Furthermore, the thumbwheel 1 further comprises two inserting pieces 13 arranged on both sides of the first mounting portion 12, the two inserting pieces 13 are both convexly arranged on the toggle body 11, and form a socket, the rotating seat 2 comprises an inserting portion 24 integrally formed with the second mounting portion 23, the inserting portion 24 is inserted into the socket, and the first fastener 7 passes through the inserting portion 24 and the second mounting portion 23, and is threadedly connected with the first mounting portion 12. The inserting portion 24 is inserted into the socket, which facilitates the positioning of the rotating seat 2 and the thumbwheel 1, and also facilitates the use of the first fastener 7 to fix the rotating seat 2 and the thumbwheel 1 together.

[0046] Furthermore, a fastening hole 121 is formed on the first mounting portion 12 , and through holes are formed on the insertion portion 24 and the second mounting portion 23 . The first fastener 7 passes through the two through holes and is threadedly connected to the fastening hole 121 .

[0047] Furthermore, the dial potentiometer also includes a second fastener 8, a first connecting hole 613 is opened on the circuit board 61, and a second connecting hole 37 is opened on the mounting base 3. The second fastener 8 passes through the first connecting hole 613 and is fastened to the second connecting hole 37, thereby realizing a fixed connection between the circuit board 61 and the mounting base 3.

[0048] Furthermore, the mounting base 3 includes a limiting column 33 , and a limiting hole 612 is provided on the circuit board 61 , and the limiting column 33 is limited in the limiting hole 612 .

[0049] Further, the number of the limiting posts 33 is at least two, and the limiting posts 33 and the limiting holes 612 are arranged in one-to-one correspondence. The arrangement of the limiting posts 33 and the limiting holes 612 can prevent loosening between the mounting base 3 and the circuit board 61 when the second fastener 8 becomes loose, ensuring the stability of their connection.

[0050] Further, the rotating base 2 includes an integrally formed rotating body 21 and a first rotating shaft 25. The above-mentioned telescopic cavity 211 is formed on the rotating body 21. The mounting base 3 includes a protruding portion, and a first rotating hole 36 is formed on the protruding portion. The first rotating shaft 25 is rotatably arranged in the first rotating hole 36.

[0051] Further, the rotating base 2 further includes a second rotating shaft 22. An avoidance hole 611 is formed on the circuit board 61, and a second rotating hole 631 is formed on the contact seat 63. After the second rotating shaft 22 passes through the avoidance hole 611, it is fixedly connected to the second rotating hole 631, so that the rotating base 2 drives the contact seat 63 to rotate.

[0052] Further, a rotating cavity 34 is formed on the mounting base 3, and the rotating body 21 is rotatably arranged in the rotating cavity 34.

[0053] As Figure 4 and Figure 5 shown, the damping member 41 includes a connecting portion 411, a convex contact portion 412, and a sleeving portion 413. The connecting portion 411 is integrally formed with the convex contact portion 412 and the sleeving portion 413 respectively. The connecting portion 411 and the sleeving portion 413 form a step, and the other end of the elastic member 42 is connected to the step. The convex contact portion 412 can be in contact with the tooth grid groove or the middle position groove 32.

[0054] Optionally, one end of the elastic member 42 is fixedly connected to the cavity wall of the telescopic cavity 211, and the other end of the elastic member 42 is fixedly connected to the step. Such an arrangement facilitates the elastic member 42 to drive the damping member 41 to expand and contract, so that the damping member 41 can be stably in contact with the tooth grid groove or the middle position groove 32, and is also convenient for sliding between each tooth grid groove and the middle position groove 32.

[0055] Optionally, one end of the elastic member 42 abuts against the cavity wall of the telescopic cavity 211, and the other end of the elastic member 42 is sleeved on the sleeving portion 413 and abuts against the step. During the entire sliding process of the damping member 41, the elastic member 42 is always in a compressed state to ensure that the elastic member 42 is always connected to the damping member 41, ensuring the reliability of the connection.

[0056] As Figure 4 and Figure 7As shown, the thumbwheel potentiometer can be simply adjusted to a thumbwheel potentiometer that automatically returns to the center position, that is, the center return potentiometer assembly that returns to the center position includes a reset center return assembly 5, but the thumbwheel with uniform damping does not need a reset center return assembly. The thumbwheel potentiometer also includes a reset center return assembly 5, and the reset center return assembly 5 is used to return the damping member 41 to its original position. The damping member 41 returns to its original position when the thumbwheel 1 is removed from the force of the thumbwheel. The damping member 41 can automatically return to a state of contact with the center slot 32. After the installation of the center return assembly, a large force is required to overcome the elastic force of the center spring to maintain the position. If the force is less than the elastic force of the center spring, it will return to the center position. After the center return spring is installed, the convex contact component can be removed.

[0057] The reset assembly 5 includes a torsion spring 51 connected to the swivel seat 2 . A movable groove 35 is provided on the mounting seat 3 . Two torsion arms of the torsion spring 51 can be movably arranged in the movable groove 35 and can abut against the groove wall of the movable groove 35 .

[0058] Specifically, the torsion spring 51 is sleeved on the protrusion, and the upper end surface of the torsion spring 51 is connected to the rotating body 21. When the damping member 41 returns to its original position, the two torsion arms of the torsion spring 51 respectively abut against the two groove walls of the notch of the movable groove 35, and the torsion spring 51 does not deform. The rotating seat 2 rotates, driving one of the torsion arms of the torsion spring 51 to move in the movable groove 35, and the other torsion arm of the torsion spring 51 abuts against the groove wall of the movable groove 35, and the torsion spring 51 is deformed. When the torsion force of the dial wheel 1 is removed, the rotating seat 2 can be reset under the action of the deformation elastic force of the torsion spring 51, and then drive the damping member 41 to return to its original position. By installing a return-to-center spring, it can be used in conjunction with the damping toggle design. It can be understood that if the damping spring and the protrusion are removed, it can be used as a return-to-center potentiometer.
