The pressure plate has a clamping hole, and the rotating arm has a first groove. The clamping hole and the first groove cooperate to fix the axial position of the rotating arm. A first limiting post is also fixed on the pressure plate, and a second limiting post is also fixed on the rotating arm.

[0027] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0028] The following describes in detail the overall structure, working principle, and technical effects of the rotary damping structure and camera 100 provided by this utility model through embodiments and in conjunction with the accompanying drawings.
[0029] Please refer to Figure 1 and Figure 2 This utility model provides a rotation damping structure applied to a rotating camera 100 to limit the rotation of the camera 100.
[0030] Specifically, the camera 100 includes a rotation damping structure. The rotation damping structure includes a first body 12 and a second body 36. The first body 12 has a wire-passing hole. The second body 36 has a rotating arm 21. The rotating arm 21 passes through the wire-passing hole, allowing the second body 36 to rotate relative to the first body 12 about the axis of the rotating arm 21. It is understood that the first body 12 has a wire-passing hole, and the second body 36 has a rotating arm 21; the rotational connection between the first body 12 and the second body 36 is achieved through a shaft hole fit. The rotation damping structure also includes a pressure plate 30. The pressure plate 30 is disposed on the side where the rotating arm 21 passes through the wire-passing hole and is fixedly connected to the first body 12. The pressure plate 30 has a clamping hole 33. The rotating arm 21 has a first groove 211. The clamping hole 33 and the first groove 211 cooperate to fix the axial position of the rotating arm 21. It is understandable that by clamping one end of the rotating arm 21 with the pressure plate 30, and the pressure plate 30 being fixedly connected to the first body 12, one end of the rotating arm 21 is restricted to one side of the first body 12 to prevent the rotating arm 21 from falling out of the wire hole.
[0031] It is understood that the camera 100 includes a housing 10 and a lens assembly 20. A first main body 12 is disposed on the housing 10. A second main body 36 is disposed on the lens assembly 20. A cavity is provided within the housing 10. The cavity is used to accommodate the wiring structure and rotational damping structure of the camera 100, achieving sealing and protection of the wiring structure and rotational damping structure.
[0032] Furthermore, the housing 10 is provided with an opening communicating with the cavity. The camera 100 also includes an antenna cover 40. The antenna cover 40 is disposed on the opening to close the cavity.
[0033] To limit the rotation of the rotating arm 21, a first limiting post is fixed to the pressure plate 30. A second limiting post is also fixed to the rotating arm 21. The rotating arm 21 rotates to move the second limiting post relative to the first limiting post, and the second limiting post abuts against the first limiting post to restrict the rotation of the rotating arm 21. It can be understood that as the pressure plate 30 and the rotating arm 21 rotate relative to each other, the second limiting post rotates to move closer to or away from the first limiting post. When the second limiting post abuts against the first limiting post, it restricts the rotating arm 21 from continuing to rotate. It can be understood that this invention can achieve the limiting function of the rotating structure, preventing excessive rotation angles from causing internal winding.
[0034] To achieve a damping effect in the rotating structure, a sealing ring is also fitted onto the rotating arm 21 in this embodiment. The sealing ring is embedded in the first groove 211. The pressure plate 30 presses the sealing ring into the first groove 211. It can be understood that the sealing ring is fitted onto the first groove 211 of the rotating arm 21, and the pressure plate 30 clamps the first groove 211 of the rotating arm 21 to press the sealing ring tightly within the first groove 211. The pressure applied to the sealing ring by the pressure plate 30 causes the sealing ring to compress and deform, generating radial pressure on the rotating arm 21. When the sealing ring squeezes the rotating arm 21 and rotates manually, friction is generated to achieve a damping effect.
[0035] Furthermore, a second groove 11 is also provided on the first body 12. The sealing ring is also embedded in the second groove 11. It can be understood that the pressure plate 30 presses the sealing ring and fixes it relative to the sealing ring. By fixing the pressure plate 30 on the first body 12 and covering the first groove 211 with the pressure plate 30, the sealing ring can be pressed into the first groove 211 simultaneously. As the pressure plate 30 gradually presses against the first body 12, the pressure between the pressure plate 30 and the first body 12 is converted into the pressure between the sealing ring and the first groove 211. The sealing ring is squeezed against the first groove 211, causing the sealing ring to undergo compression deformation, generating axial pressure on the first body 12. The sealing ring squeezes the first body 12 to produce a sealing effect.
[0036] To facilitate the installation and removal of the pressure plate 30, in this embodiment, the pressure plate 30 includes a first clamping plate 31 and a second clamping plate 32. The first clamping plate 31 and the second clamping plate 32 are disposed on both sides of the rotating arm 21. When the first clamping plate 31 and the second clamping plate 32 clamp the rotating arm 21, a clamping hole 33 is formed between the first clamping plate 31 and the second clamping plate 32. The first clamping plate 31 and the second clamping plate 32 are respectively fixedly connected to the first body 12.
[0037] Specifically, the first clamping plate 31 and the second clamping plate 32 are respectively provided with arc-shaped notches. When the first clamping plate 31 and the second clamping plate 32 are combined, the two arc-shaped notches form clamping holes 33, so that the first clamping plate 31 and the second clamping plate 32 clamp the rotating arm 21. It can be understood that when installing the pressure plate 30, the first clamping plate 31 and the second clamping plate 32 are inserted into the first groove 211 of the rotating arm 21 from both sides of the rotating arm 21, abutting against the sealing ring, and then the first clamping plate 31, the second clamping plate 32 and the first body 12 are fixedly connected to complete the installation. When disassembling the pressure plate 30, the connection between the first clamping plate 31, the second clamping plate 32 and the first body 12 is disengaged, and the first clamping plate 31 and the second clamping plate 32 are separated, so that the rotating arm 21 can be disassembled from the wire hole.
[0038] Furthermore, the pressure plate 30 is detachably connected to the first body 12 by screws. The screws include a first screw 34 and a second screw 35. The first screw 34 is recessed below the plane of the pressure plate 30. The second screw 35 protrudes from the plane of the pressure plate 30 to form a first limiting post. It is understood that the first screw 34 is a countersunk screw, embedded within the plane of the pressure plate 30. The screw head of the second screw 35 protrudes from the plane of the pressure plate 30 to form the first limiting post. A third screw 212 is also provided on the rotating arm 21, protruding from the side of the rotating arm 21 to form a second limiting post. It is understood that when the rotating arm 21 rotates, the third screw 212 rotates and moves relative to the second screw 35. When the third screw 212 abuts against the second screw 35, it restricts the rotating arm 21 from continuing to rotate. This utility model achieves limiting of the rotating structure through a simple screw structure, reducing the cost of the limiting structure, and is simple to install and stable and reliable.
[0039] Specifically, in this embodiment, two second screws 35 are respectively disposed on both sides of the rotating arm 21, and a third screw 212 is disposed between the two second screws 35. It is understood that the rotating arm 21 can rotate clockwise or counterclockwise relative to the first body 12. In this embodiment, by providing second screws 35 on both sides of the rotating arm 21, the two rotational directions of the rotating arm 21 can be limited. Specifically, when the rotating arm 21 rotates clockwise, the third screw 212 abuts against the second screw 35 on one side of the rotating arm 21 to limit the rotation of the rotating arm 21 in this direction; when the rotating arm 21 rotates counterclockwise, the third screw 212 abuts against the second screw 35 on the other side of the rotating arm 21 to limit the rotation of the rotating arm 21 in the other direction.
[0040] In this embodiment, a second screw 35 is provided on both the first clamping plate 31 and the second clamping plate 32.
[0041] Furthermore, the angle between the two second screws 35 and the line connecting the rotation axis of the rotating arm 21 is less than or equal to 180°. It is understood that this arrangement ensures that the maximum rotation angle of the rotating arm 21 is less than or equal to 180°, preventing the internal wiring of the camera 100 from becoming tangled.
[0042] Specifically, in this embodiment, the axis of the first limiting post is parallel to the axis of the rotating arm 21. The second limiting post is arranged radially along the rotating arm 21. It can be understood that the first screw 34 and the second screw 35 fix the pressure plate 30 to the first body 12 in a direction perpendicular to the plane of the pressure plate 30. The third screw 212 is arranged radially along the rotating arm 21 so that the rotation angle of the rotating arm 21 is the same as the angle between the position of the third screw 212 before and after rotation, facilitating the adjustment of the maximum rotation angle of the rotating arm 21 by adjusting the position of the second screw 35.
[0043] The beneficial effects of the rotational damping structure and camera 100 provided in this embodiment of the invention include:
[0044] The rotation damping structure of the camera 100 of this utility model includes a first body 12, a second body 36, and a pressure plate 30. The first body 12 has a wire-passing hole, and the second body 36 is provided with a rotating arm 21. The rotating arm 21 passes through the wire-passing hole, allowing the second body 36 to rotate relative to the first body 12 about the axis of the rotating arm 21. The pressure plate 30 is disposed on the side where the rotating arm 21 passes through the wire-passing hole and is fixedly connected to the first body 12. The pressure plate 30 is provided with a clamping hole 33. The rotating arm 21 has a first groove 211, and the clamping hole 33 and the first groove 211 cooperate to fix the axial position of the rotating arm 21. A first limiting post is also fixed to the pressure plate 30. A second limiting post is also fixed to the rotating arm 21. The rotating arm 21 rotates to drive the second limiting post to move relative to the first limiting post. The second limiting post abuts against the first limiting post to restrict the rotation of the rotating arm 21. This invention uses a pressure plate 30 to clamp one end of the rotating arm 21 to one side of the wire hole, thereby positioning the rotating arm 21. By providing a first limiting post and a second limiting post, the second limiting post abuts against the first limiting post to restrict the rotation of the rotating arm 21. This invention achieves the limiting function of the rotating structure of the camera 100, preventing excessive rotation angle from causing internal wire winding.
[0045] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
