As shown in fig. 1 and 2, the rotational damping module 1 is used for providing damping effect to two relatively rotating components (not shown), the rotational damping module 1 includes a base 10, a disc 20, and a damping structure 30, wherein the base 10 and the disc 20 can be respectively connected to the relatively rotating components, the base 10 is pivotally provided with a pivot pipe 12, the pivot pipe 12 is pivotally provided with the disc 20, so that the disc 20 and the base 10 rotate relatively, the pivot pipe 12 is pivotally provided with the damping structure 30 between the base 10 and the disc 20, so that the base 10 and the disc 20 respectively drive the relatively rotating components to stop rotating relatively.

The damping structure 30 mainly comprises a pressing member 32 and a first friction member 34, wherein the pressing member 32 and the first friction member 34 are axially arranged between the base 10 and the disc 20 in the pivot pipe 12, the first friction member 34 abuts against the disc 20, the pressing member 32 abuts against the base 10 and the first friction member 34, the pressing member 32 is a disc spring, the pressing member 32 forms a positive force to the first friction member 34, so that the first friction member 34 abuts against the disc 20 to form a relative friction; the pressing member 32 can be replaced by a wave spring instead of a disc spring.

Through the above structure, the operation of the present invention is described as follows: since the pressing member 32 forms a positive force on the first friction member 34, so that the first friction member 34 and the disc 20 are abutted against each other, and the first friction member 34 and the disc 20 are abutted against each other along the axial direction of the pivot tube 12, as shown in fig. 7 and 8, when the rotary damping module 1 is disposed on a lens supporting device 2, the lens supporting device 2 includes a base 60, a rotary plate 70 and a set portion 80, wherein the rotary plate 70 is disposed on the top edge of the base 60, the set portion 80 is disposed on the top edge of the rotary plate 70, the set portion 80 is used for disposing a lens (not shown) and the rotary plate 70 and the base 60 can rotate relatively, thereby changing the direction of the lens disposed on the set portion 80, the rotary damping module 1 is disposed between the base 60 and the rotary plate 70, the base 60 is connected with the base 10, the rotary plate 70 is connected with the disc 20, further, the base 60 forms a first caulking groove 62 in cooperation with the base 10, the base 10 is inserted into the first slot 62, so that the base 60 is connected to the base 10, the turntable 70 cooperates with the disk 20 to form a second slot (not shown), and the disk 20 is inserted into the second slot, so that the turntable 70 is connected to the disk 20.

When the base 60 and the turntable 70 respectively drive the base 10 and the disk 20 to rotate relatively, the first friction member 34 and the disk 20 form a relative friction, the friction gradually reduces the kinetic energy of the relative rotation between the base 10 and the disk 20, the relative rotation between the base 10 and the disk 20 gradually stops, and the relative rotation between the base 60 and the turntable 70 also gradually stops, on the other hand, when the base 60 and the turntable 70 are in a relatively static state, if the acting force applied externally cannot overcome the static friction force between the first friction member 34 and the disk 20, the base 60 and the turntable 70 cannot be driven to change from the relatively static state to the relatively rotating state, and the base 60 and the turntable 70 are prevented from rotating randomly due to unexpected small external forces such as breeze and gravity.

It should be mentioned that the rotation damping module 1 assembled in advance can be applied to a lens support frame installed on a monitoring device, a pan/tilt head for installing a video camera, or other devices capable of stopping automatically when rotating, and avoiding the inertia continuous rotation state, the rotation damping module 1 is used for making the friction force output of the rotation stop stable, and when the rotation damping module 1 is installed on the above devices, the devices only need to be matched to enable the base 10 and the disk 20 to be embedded respectively, the installation of the rotation damping module 1 can be completed, and the rotation damping module 1 is easily assembled on the lens support device 2.
