It is understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for the convenience of description, only the parts related to the utility model are shown in the accompanying drawings.

[0042] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0043] Please refer to Figures 1 to 8 The embodiment of the utility model provides a new type of pan / tilt head, including a base 1, a main body 2 and a mounting frame 3; the main body 2 includes a lower shell 21 and an upper shell 22; the base 1 is arranged below the lower shell 21, and a vertical shaft 11 penetrating the base 1 is fixedly arranged on the base 1, and the top of the vertical shaft 11 is rotatably connected to the lower shell 21 through a bearing; the mounting frame 3 is arranged on the upper shell 22, and the upper shell 22 is rotatably connected to a main shaft 31 through a bearing, and both ends of the main shaft 31 are fixedly connected to the mounting frame 3 respectively;

[0044] An upper damping assembly 4 is arranged between one side of the upper shell 22 and the mounting frame 3; a first adjusting assembly 5 is arranged in the upper shell 22 and is transmission-connected to the upper damping assembly 4, and is used to adjust the damping value of the upper damping assembly 4; a first adjusting knob 51 is arranged on the outer side of the upper shell 22 and is fixedly connected to the first adjusting assembly 5;

[0045] A dynamic balancing assembly 6 is disposed between the other side of the upper shell 22 and the mounting frame 3; an adjusting wheel 61 is rotatably connected to the outer periphery of the first adjusting knob 51 on the outer side of the upper shell 22 for adjusting the balancing torque of the dynamic balancing assembly 6;

[0046] The lower shell 21 is rotationally connected to the base 1 via the lower damping assembly 7 . A second adjustment assembly 8 is provided in the lower shell 21 and is transmission-connected to the lower damping assembly 7 for adjusting the damping value of the lower damping assembly 7 .

[0047] In this embodiment, when the operator of the current pan-tilt head performs rotation adjustment, the adjustment structures distributed on both sides affect the stability of the pan-tilt head rotation during actual use.

[0048] The gimbal of the present application designs the first adjustment knob 51 for adjusting the pitch rotation and the adjustment wheel 61 for adjusting the dynamic balance as a concentric structure, realizing one-handed adjustment and control. Its structural design is reasonable, which greatly improves the convenience of using the equipment.

[0049] In a preferred embodiment, if Figure 2 , 5 As shown in Figures 6 and 7, the upper damping assembly 4 includes a first damping disc 41 and a second damping disc 42 which are arranged in parallel; the first damping disc 41 is fixedly arranged in the mounting frame 3 and is located at the outer periphery of the main shaft 31, and a plurality of concentric first annular grooves 43 are uniformly distributed on the disc surface of the first damping disc 41 close to the second damping disc 42; the second damping disc 42 is movably and rotatably arranged in the upper shell body 22 along its axial direction, and a first damping ring 44 corresponding to the first annular groove 43 is arranged on the disc surface of the second damping disc 42, and the first damping ring 44 is embedded in the corresponding first annular groove 43, and a certain amount of damping grease is filled in the first annular groove 43.

[0050] In this embodiment, the camera is mounted on the mounting frame 3, and the steering lever is connected to the mounting frame 3. The camera angle is adjusted by rotating the mounting frame 3 through the steering lever. The mounting frame 3 is rotatably connected to the upper housing 22 through the main shaft 31 to achieve the pitch rotation of the camera. When the mounting frame 3 is pitched, the first damping disc 41 and the second damping disc 42 rotate in the opposite direction. The deeper the first damping ring 44 is embedded in the first annular groove 43, the greater the damping force, and vice versa, the smaller the damping force, thereby ensuring the adaptability of the pitch rotation.

[0051] In a preferred embodiment, if Figure 2 , 5 As shown in Figures 6 and 7, the first adjusting assembly 5 includes a turbine 52, a worm 53 and a threaded sleeve 54; the turbine 52 is rotatably sleeved on the main shaft 31, and first limit members 23 are respectively provided at both ends of the turbine 52 in the upper shell 22; the worm 53 is meshed with the turbine 52, one end of the worm 53 extends out of the upper shell 22 and is fixedly connected to the first adjusting knob 51; one end of the threaded sleeve 54 is concentrically fixedly connected to the second damping disk 42, and the threaded sleeve 54 is threadedly sleeved with the turbine 52.

[0052] In this embodiment, the first adjusting knob 51 is rotated to drive the worm 53 to rotate. Preferably, a rotating handle is provided on the first adjusting knob 51 to facilitate the rotation operation of the first adjusting knob 51. The worm 53 drives the turbine 52 to rotate. The first position-limiting member 23 is provided so that the turbine 52 can only rotate axially without axial movement. With the cooperation of the threaded structure, the threaded sleeve 54 moves axially relative to the turbine 52, thereby driving the second damping disk 42 to move, thereby realizing the adjustment of the depth of the first damping ring 44 embedded in the first annular groove 43, that is, realizing the adjustment of the magnitude of the pitch rotation damping force, so as to adapt to different models of cameras and operators with different usage habits, and ensure the adaptability of the camera pitch rotation.

[0053] The precise adjustment of the movement of the second damping plate 42 can be achieved by designing the transmission ratio of the turbine 52 and the worm 53. Preferably, the transmission ratio of the turbine 52 and the worm 53 is 3 to 4:11.

[0054] In a preferred embodiment, if Figure 2 , 5 As shown in , 7, the dynamic balancing assembly 6 includes the same number of dynamic balancing discs 62 and clamping parts 63; a plurality of dynamic balancing discs 62 are fixedly sleeved on the main shaft 31, and the dynamic balancing disc 62 includes a concentric inner ring 621 and an outer ring 622, and the inner ring 621 and the outer ring 622 are fixedly connected by rubber 623; a positioning groove 624 is opened on the outer side of the outer ring 622;

[0055] A support shaft 64 is provided in the upper shell 22 between the dynamic balancing disc 62 and the adjusting wheel 61.

[0056] In this embodiment, the inner ring 621 is fixedly connected to the mounting frame 3 through the main shaft 31, and the outer ring 622 is fixedly connected to the upper housing 22 through the clamping member 63 and the support shaft 64. When the inner ring 621 and the outer ring 622 rotate relative to each other, the rubber 623 is deformed, thereby outputting a force that prevents the inner ring 621 and the outer ring 622 from rotating relative to each other, that is, a balancing torque. The balancing torque can offset the effect of the camera's own weight on the pan / tilt motion, thereby ensuring the adaptability of the pan / tilt rotation and reducing the difficulty of the operator.

[0057] Preferably, the dynamic balancing disc 62 is provided with one 1kg balancing torque and two 2kg balancing torques. By adjusting the number of the engaging parts 63, that is, the number of the hooks 65 embedded in the positioning slots 624, the dynamic balancing assembly 6 can be obtained to have five levels of balancing torque of 1kg, 2kg, 3kg, 4kg, and 5kg, which has a wide range of adaptability.

[0059] In this embodiment, when the adjusting wheel 61 is rotated, the engagement and disengagement of the hook 65 can be switched through the cooperation of the groove 69 and the protrusion 68, thereby adjusting the number of effective dynamic balancing discs 62, and the adjustment is convenient. Preferably, an anti-skid groove is provided on the periphery of the adjusting wheel 61 to facilitate the rotation of the adjusting wheel 61 to adjust the balancing torque of the dynamic balancing assembly 6.

[0060] Taking the example of the dynamic balancing disc 62 being provided with one 1kg balancing torque and two 2kg balancing torques, the adjusting wheel 61 is provided with 6 gears accordingly. Each rotation of the adjusting wheel 61 by 60° is one gear, and the 6 gears are respectively:

[0061] 0 gear position, that is, the balance torque is 0, there is no groove 69 at the corresponding position on the adjusting wheel 61, so the protrusion 68 is pushed to disengage all the hooks 65;

[0062] 1kg gear, a groove 69 is provided on the adjusting wheel 61 at a position corresponding to the 1kg dynamic balancing disc 62, and the corresponding protrusion 68 is embedded in the positioning slot 624, so that the 1kg dynamic balancing disc 62 is connected to the structure, and the other two dynamic balancing discs 62 are disengaged from the clamping member 63;

[0063] In the 2kg gear position, a groove 69 is provided on the adjusting wheel 61 at a position corresponding to any 2kg dynamic balancing disc 62, and the other two dynamic balancing discs 62 are disengaged from the clamping member 63;

[0064] The same is true for the 3kg gear, 4kg gear, and 5kg gear, and the corresponding dynamic balancing disc 62 enters the working state.

[0065] Preferably, a gear positioning assembly is provided between the adjusting wheel 61 and the upper shell 22, so that the adjusting wheel 61 can be accurately rotated to the corresponding gear position during adjustment.

When the positioning ball is embedded in the hemispherical groove, the groove 69 is matched with the protrusion 68.

[0067] In this embodiment, the structural principle of the lower damping assembly 7 is the same as that of the upper damping assembly 4, except that the lower damping assembly 7 is arranged horizontally.

Under the limiting action of the second limiting member 24, the external threaded sleeve 83 can only rotate and cannot generate axial movement. Under the cooperation of the threaded structure of the external threaded sleeve 83 and the internal threaded sleeve 84, the rotating external threaded sleeve 83 drives the internal threaded sleeve 84 to move up and down, thereby driving the fourth damping disc 72 to move up and down, realizing the adjustment of the depth of the second damping ring 74 embedded in the second ring groove 73, which is convenient to adjust and has high precision.
