[0032] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0033] Reference Figure 1 A damper includes: a base 500, a first plate 100, a second plate 200, a damping structure 400 and a connecting structure 300, wherein the base 500 is provided with a through hole 550; the first plate 100 is provided with a first connecting hole 150, and the first plate 100 can rotate around the first connecting hole 150; the second plate 200 is provided with a second connecting hole 250, and the through hole 550, the first connecting hole 150 and the second connecting hole 250 are coaxial; the damping structure 400 is located between the first plate 100 and the second plate 200 and is used to hinder the relative rotation between the first plate 100 and the second plate 200; the base 500 is connected to the second plate 200 as a whole through the connecting structure 300, and the first plate 100 can rotate relative to the second plate 200 or the base 500. When the first plate 100 rotates around the first connecting hole 150, the first plate 100 will rotate relative to the second plate 200. During this process, the damping structure 400 will apply a damping force between the first plate body 100 and the second plate body 200, thereby hindering the relative rotation of the two, and thus improving the stability of the device such as the gimbal when adjusting the angle. The connecting structure 300 connects the base 500, the first plate body 100 and the second plate body 200 to each other as a whole. As a result, the damper can form a whole, and the device such as the gimbal can conveniently use multiple dampers in combination. When multiple dampers operate together in the gimbal, since each damper is connected as a whole through the connecting structure 300, when the gimbal is adjusted in steering, each damper can avoid affecting each other, so that each damper can stably and effectively provide a damping effect in the gimbal, so that the gimbal can obtain a variety of damping effects through the cooperation of multiple dampers.

[0034] In certain embodiments, reference Figure 2The damping structure 400 includes a first ring body 410 and a second ring body 420. The first ring bodies 410 are multiple and are all arranged on the first disk body 100, and each of the first ring bodies 410 is nested in sequence; the second ring bodies 420 are multiple and are all arranged on the second disk body 200, and each of the second ring bodies 420 is nested in sequence; at least one second ring body 420 extends between two adjacent first ring bodies 410, and damping oil is arranged between the first ring body 410 and the second ring body 420. The first ring body 410 and the second ring body 420 are nested with each other, so when the first disk body 100 and the second disk body 200 rotate relative to each other, the first disk body 100 and the second disk body 200 will move relative to each other. In this process, the damping oil will apply a damping force between the first ring body 410 and the second ring body 420, so that the relative rotation between the first disk body 100 and the second disk body 200 is damped, and the purpose of the damper applying a damping effect to the outside world can be smoothly achieved.

[0035] It is conceivable that damping oil may be directly applied between the first plate body 100 and the second plate body 200. The specific implementation method may be adjusted accordingly according to actual needs and is not limited here.

[0036] In certain embodiments, reference Figure 2 The second plate body 200 is sleeved on the outer periphery of the first plate body 100, and the second plate body 200 and the base 500 cooperate to shield the first plate body 100. The sleeve effect of the second plate body 200 on the first plate body 100 can effectively shield the first plate body 100, so that when the first plate body 100 rotates, it will be difficult to be affected by the outside world, and its own rotation movement can be carried out more smoothly, so as to ensure that the first plate body 100 can smoothly follow the movement of the shaft component and exert a damping effect on it.

[0037] It is conceivable that the second plate 200 and the base 500 can be connected to the first plate 100 only from two sides thereof, as long as the first plate 100 is prevented from being blocked from moving. The specific implementation method can be adjusted accordingly according to actual needs and is not limited here.

[0038] In certain embodiments, reference Figure 2The second tray body 200 includes a side surrounding portion 220 and a top covering portion 210. The side surrounding portion 220 covers the outer periphery of the first tray body 100, and the top covering portion 210 covers the end surface of the first tray body 100. The connecting structure 300 passes through the side surrounding portion 220 and is connected to the base 500. The first connecting hole 150 is located in the middle of the top covering portion 210. The side surrounding portion 220 can surround the first tray body 100 from the circumferential direction of the first tray body 100, while the top covering portion 210 can cover the first tray body 100 from the end surface of the first tray body 100 and cooperate with the base 500 to shield the two ends of the first tray body 100. In this way, the ends and sides of the first tray body 100 are covered, so that its rotation movement can be effectively prevented from being hindered. Furthermore, the side surrounding portion 220 can also provide a positioning point for the connection structure 300, so that the connection structure 300 can accurately connect and fix the second plate body 200 and the base 500, thereby allowing the first plate body 100, the second plate body 200 and the base 500 to be smoothly connected as a whole.

[0039] In certain embodiments, reference Figure 3 A positioning boss 170 is provided in the middle of the first plate body 100, and the first connecting hole 150 is provided in the middle of the positioning boss 170; the positioning boss 170 is inserted into the second connecting hole 250. The positioning boss 170 can perform radial positioning between the first plate body 100 and the second plate body 200, thereby ensuring that the first connecting hole 150 and the second connecting hole 250 have sufficient coaxiality, and the two can cooperate to load shaft components.

[0040] In certain embodiments, reference Figure 3 The connection structure 300 includes a connection member 350, which penetrates the second tray 200 and the base 500 and connects and fixes the two. The connection member 350 can not only smoothly connect the second tray 200 and the base 500, but also has the characteristics of easy installation and not easy to fail, so the second tray 200 and the base 500 can be effectively connected as a whole. In addition, the connection member 350 can also position the first tray 100 from the circumferential side direction, so that the first tray 100, the second tray 200 and the base 500 can smoothly form an integrated structure.

[0041] Specifically, the connecting member 350 is a rivet. There are four connecting members 350, and the four connecting members 310 are distributed around the first plate body 100. Of course, the number of connecting members 350 is not unique, and the specific implementation method can be adjusted accordingly according to actual needs, and is not limited here.

[0042] It is conceivable that the connection structure 300 may also be composed of other components, such as bolts, or the second plate 200 and the base 500 may be directly welded together. The specific implementation method may be adjusted accordingly according to actual needs and is not limited here.

[0043] Reference Figure 4 The second aspect of the utility model provides an embodiment of a photographic pan head, comprising the above damper, and: a base 600 and a connecting base 700, wherein the base 600 is provided with a rotating shaft 650; the connecting base 700 is connected to the base 600 through the rotating shaft 650, and the connecting base 700 can rotate relative to the base 600; wherein the rotating shaft 650 is sleeved with at least two dampers, and both dampers can hinder the relative rotation between the base 600 and the connecting base 700. The connecting base 700 can be used to connect photographic equipment, and the base 600 can be used to connect components such as legs, and enable the photographic equipment to obtain a supporting effect. When the photographic equipment is adjusted in angle, the connecting base 700 will be driven to rotate relative to the base 600. During the rotation of the connecting base 700, each damper will exert a damping effect on the relative rotation of the connecting base 700 and the base 600, and the movement stability of the connecting base 700 will be improved through the cooperation of each damper. When multiple dampers work together, since each damper is connected as a whole through the connecting structure 300, the dampers can avoid affecting each other when the connecting seat 700 is turned and adjusted, so that each damper can stably and effectively provide a damping effect between the connecting seat 700 and the base 600, thereby meeting different damping requirements and improving the product competitiveness of the gimbal.

[0044] In certain embodiments, reference Figure 5 At least two of the dampers connected to the rotating shaft 650 have different damping forces. The dampers with different damping forces can provide the rotating shaft 650 with a variety of damping variation effects, thereby effectively increasing the variation of the damping force received by the rotating shaft 650, thereby making the rotation of the rotating shaft 650 more stable and improving the rotation stability of the connecting seat 700.

[0045] In certain embodiments, reference Figure 7 , a pin 910 is provided in the base 600, and a plurality of grooves 930 are provided on the periphery of the base 500; when the base 600 rotates relative to the connecting base 700, the pin 910 can move closer to and engage with the groove 930 or move away from the groove 930. The separation and engagement between the pin 910 and the groove 930 can smoothly apply resistance between the base 500 and the pin 910, thereby achieving the effect of applying a damping force between the base 600 and the connecting base 700 through the base 500.

[0046] Specifically, a connecting wheel 930 is installed on the outer periphery of the pin 910 , and contacts the groove 920 through the connecting wheel 930 .

[0047] In certain embodiments, reference Figure 4 The base 600 is connected to a rotating base 800, which is connected to the rotating shaft 650 and can rotate relative to it; the rotating base 800 is provided with a connecting shaft 850, which is staggered with the rotating shaft 650, and the connecting base 700 is rotatably connected to the connecting shaft 850, and a damper is installed on the periphery of the connecting shaft 850. The base 600, the rotating base 800 and the connecting base 700 can rotate in different dimensions in sequence, so the photographic equipment can be adjusted in various directions relative to the base 600 through the connecting base 700, and the photographic equipment can fully adjust itself to a predetermined orientation angle. The damper can exert a damping effect at the connecting shaft 850, so that the rotation of the rotating base 800 can also become more stable and reliable.

[0048] In certain embodiments, reference Figure 6 A plurality of dampers are installed on the outer circumference of the connecting shaft 850, wherein at least two dampers have different damping forces. The plurality of dampers can provide sufficient damping effect to the connecting shaft 850, and with the different damping forces, the connecting shaft 850 can rotate more smoothly when rotating.

[0049] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
