[0020] Reference Figures 1-6 This utility model provides a damping device, including a base 100, a rotating seat 200, a gear adjustment component 300, and at least one set of damping components 400; A damping cavity 500 is provided on the base 100; The rotating seat 200 is rotatably mounted on the base 100 and at least partially extends into the damping cavity 500; The damping assembly 400 is disposed in the damping cavity 500. The damping assembly 400 includes a first damping disk 410, a second damping disk 420 and a third damping disk 430. Damping fluid is filled between the first damping disk 410, the second damping disk 420 and the third damping disk 430. The third damping disk 430 is located between the first damping disk 410 and the second damping disk 420 and is connected to the rotating seat 200. The gear adjustment assembly 300 has several damping gears. When the gear adjustment assembly 300 is in different damping gears, it can be connected to the first damping disc 410 and / or the second damping disc 420 to adjust the damping force between the rotating seat 200 and the base 100.

[0021] In this invention, during use, the gear adjustment component 300 is connected to the first damping disc 410 and / or the second damping disc 420 to allow the damping device to enter different damping gears. Different damping gears have different damping forces, thereby adjusting the damping force between the rotating seat 200 and the base 100. Specifically, the third damping disc 430 is connected to the rotating seat 200. When the gear adjustment component 300 is not connected to either the first damping disc 410 or the second damping disc 420, the first damping gear is generated. When the gear adjustment component 300 is only connected to the first damping disc 410, the second damping gear is generated. When the gear adjustment component 300 is only connected to the second damping disc 420, the third damping gear is generated. When the gear adjustment component 300 is connected to both the first damping disc 410 and the second damping disc 420, the fourth damping gear is generated. Users can switch between different damping gears according to their needs to meet shooting requirements.

[0022] Reference Figures 2-5 In some embodiments, the first damping disc 410 is provided with a plurality of first damping ring grooves 411, the second damping disc 420 is provided with a plurality of second damping ring grooves 421, and the third damping disc 430 is provided with a plurality of first damping ring blocks 431 inserted into the first damping ring grooves 411 and a plurality of second damping ring blocks 432 inserted into the second damping ring grooves 421. The number of first damping ring grooves 411 and first damping ring blocks 431 is different from the number of second damping ring grooves 421 and second damping ring blocks 432. Preferably, the first damping ring grooves 411 and first damping ring blocks 431 are arranged in a plurality of first damping ring grooves 411 and second damping ring blocks 432. Five damping ring blocks 431 are provided, and four second damping ring grooves 421 and two second damping ring blocks 432 are provided. Specifically, since the number of first damping ring grooves 411 and first damping ring blocks 431 is different from the number of second damping ring grooves 421 and second damping ring blocks 432, the damping forces generated when the first damping disc 410 is combined with the third damping disc 430, the second damping disc 420 is combined with the third damping disc 430, and the first damping disc 410 and the second damping disc 420 are simultaneously combined with the third damping disc 430 will be different, thus generating multiple different damping levels.

[0023] Reference Figures 2-5 In some embodiments, the gear adjustment assembly 300 includes an adjustment ring 310, a plurality of adjustment rods 320, and a plurality of reset members 330; the first damping disc 410 and the second damping disc 420 are circumferentially provided with a plurality of clutch grooves 340; the adjustment ring 310 is rotatably mounted on the base 100; the adjustment rods 320 are movably mounted in the base 100 and abut against the adjustment ring 310, and a clutch block 350 is provided on the adjustment rods 320; the reset members 330 are disposed between the adjustment rods 320 and the base 100; the adjustment ring 310 can push against the adjustment rods 320 when rotating, so that the clutch block 350 extends into the clutch groove 340 or moves out of the clutch groove 340.

[0024] Taking two adjusting rods 320 as an example, the first clutch block 350 on the first adjusting rod 320 can extend into or move out of the first clutch groove 340 on the first damping disc 410, and the second clutch block 350 on the second adjusting rod 320 can extend into or move out of the second clutch groove 340 on the second damping disc 420. Specifically, when the first clutch block 350 moves out of the first clutch groove 340 and the second clutch block 350 moves out of the second clutch groove 340, the first damping disc 410 and the second damping disc 420 will rotate simultaneously with the third damping disc 430, generating the first damping position; when the first clutch block 350 moves out of the first clutch groove 340 and the second clutch block 350 extends into the second clutch groove 340, the second damping disc... 420 will be restricted from rotation. At this time, only the first damping disc 410 and the third damping disc 430 rotate together, generating the second damping position. When the first clutch block 350 extends into the first clutch groove 340 and the second clutch block 350 moves out of the second clutch groove 340, the first damping disc 410 will be restricted from rotation. At this time, only the second damping disc 420 and the third damping disc 430 rotate together, generating the third damping position. When the first clutch block 350 extends into the first clutch groove 340 and the second clutch block 350 extends into the second clutch groove 340, the first damping disc 410 and the second damping disc 420 will be restricted from rotation at the same time. At this time, only the third damping disc 430 rotates, generating the fourth damping position. The damping force of the first damping position, the second damping position, the third damping position and the fourth damping position gradually increases.

[0025] Reference Figure 5 In some embodiments, the adjusting ring 310 is provided with alternating protrusions 311 and grooves 312, and the adjusting rod 320 can switch between the protrusions 311 and the grooves 312. By switching between the protrusions 311 and the grooves 312 with different adjusting rods 320, multiple combinations can be generated between the clutch blocks 350 on different adjusting rods 320 and the corresponding clutch grooves 340, thereby generating multiple damping levels.

[0026] Reference Figures 1-3In some embodiments, the base 100 includes a top seat 110 and a base 120 connected to the top seat 110 via a detachable structure 600. The top seat 110 and the base 120 form a damping cavity 500, and the rotating seat 200 is mounted on the top seat 110. Preferably, the detachable structure 600 is a bolted connection structure. Further, a first bearing 710 is provided between the rotating seat 200 and the top seat 110, and a second bearing 720 is provided between the rotating seat 200 and the base 120. The damping assembly 400 is located between the first bearing 710 and the second bearing 720. The smoothness and stability of the rotation between the rotating seat 200 and the base 100 are improved by the cooperation of the first bearing 710 and the second bearing 720.

[0027] Reference Figures 2-3 In some embodiments, the damping components 400 are configured as two and stacked in the height direction. The combination of the level adjustment component 300 and the two damping components 400 can produce more damping levels, making the damping adjustment more delicate and meeting more shooting needs.

[0028] This utility model also provides a gimbal, including the aforementioned damping device.

[0029] The advantages of this invention are: the structure described above enables precise switching of various damping forces, allowing users to adjust it flexibly according to shooting needs, adapting to different weights of photography equipment or operating intensities. It also avoids operational stuttering caused by sudden changes in damping force, making the rotation process smoother and improving the stability of the captured image.
