[0002] Unmanned aircraft, also known as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices. Drones are actually a general term for unmanned aircraft, which are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices. With the development of photography technology, ground photography can no longer meet the needs of daily operations, such as shooting a certain part of a power tower for emergency repairs, aerial views of cities, and image information collection in complex environments. With the popularization of drone technology, with the help of drone flight platforms and combined with shooting lenses, it can be used in different industry applications. Currently, commonly used drones with aerial photography functions can observe drone flight environment information in real time on the ground through data transmission.

[0003] Since the drone's own structural settings affect the shooting angle of the camera it carries, it cannot adapt well to various shooting angles. In addition, since the general environment of drone shooting is relatively complex and the take-off and landing conditions are poor, during the landing process, the landing gear may press on stones and other debris. The bounced debris can easily cause damage to the camera device at the bottom of the fuselage, causing huge losses. Utility Model Content

[0024] The telescopic mechanism 8 includes a motor 81, one end of the motor 81 is connected to a first gear 82, one side of the first gear 82 is meshed with a second gear 83, the interior of the second gear 83 is fixedly connected to a first contraction sleeve rod 84, the first contraction sleeve rod 84 is rotatably connected to the bottom of the drone body 1, the first contraction sleeve rod 84 is spirally slidably connected to the second contraction sleeve rod 86, the inner wall of the first contraction sleeve rod 84 is provided with a spiral groove 88, the surface of the second contraction sleeve rod 86 is provided with a cam bead 85, the cam bead 85 is slidably connected to the spiral groove 88, the inner wall of the second contraction sleeve rod 86 is spirally slidably connected to the second contraction sleeve rod 86, and the first contraction sleeve rod 84 is provided with a spiral groove 88. The third contraction sleeve 87 is dynamically connected to the unmanned aerial vehicle body 1, and the third contraction sleeve 87 is provided with a spring 10. One end of the spring 10 is fixedly connected to the inner bottom surface of the third contraction sleeve 87, and the other end of the spring 10 is fixedly connected to the bottom of the unmanned aerial vehicle body 1. The spring 10 enables the third contraction sleeve 87 to have a certain anti-torque function. The bottom of the third contraction sleeve 87 is rotatably connected to the retracting mechanism 9, and the bottom axis of the third contraction sleeve 87 is fixedly connected to the camera 6. The length of the first contraction sleeve 84 is longer than that of the second contraction sleeve 86, and the length of the second contraction sleeve 86 is longer than that of the third contraction sleeve 87.

[0025] The retracting and releasing mechanism 9 includes a support rod 91, which is rotatably connected to the bottom of the third shrinking sleeve rod 87. Both ends of the support rod 91 are rotatably connected to connecting rods 92. The other end of the connecting rod 92 is slidably connected to a limiting slide groove 93. The limiting slide groove 93 is fixedly connected to the inner wall of the protective cover 7. One end of the limiting slide groove 93 is provided with an anti-slip baffle 11 to prevent the connecting rod 92 from escaping from the inner wall of the limiting slide groove 93.

[0026] Working principle: After the drone takes off and reaches the shooting position, the drone remote control device is used to start the telescopic mechanism 8. Under the action of the motor 81, the first gear 82 and the second gear 83 are driven to rotate, and the first contraction sleeve rod 84 is driven to rotate at the same time. Under the rotation of the first contraction sleeve rod 84, the second contraction sleeve rod 86 is forced to slide downward on the inner wall of the spiral groove 88 set on the inner wall of the first contraction sleeve rod 84 through the cam bead 85 set on its surface. The second contraction sleeve rod 86 drives the third contraction sleeve rod 87 to slide downward inside the second contraction sleeve rod 86 in the above-mentioned manner. At the same time, driven by the third contraction sleeve rod 87, the retracting and releasing mechanism 9 starts to work. When the support rod 91 moves downward synchronously, it drives the connecting rod 92 to move, so that the other end of the connecting rod 92 The inner wall of the limiting slide groove 93 slides downward, causing the protective cover 7 to open. At this time, the camera 6 is just extended to the position shown in the figure. Through such a setting, not only the landing gear 5 is prevented from blocking the shooting field of view of the camera 6 after the drone takes off, but also when landing, under the action of the retracting mechanism 9, the motor 81 rotates in the opposite direction, driving the first gear 82 and the second gear 83 to rotate in the opposite direction, so that the first contraction sleeve rod 84 drives the second contraction sleeve rod 86 to rotate in the opposite direction and contract, and then drives the third contraction sleeve rod 87 to contract and lift, so that the camera 6 is retracted into the inside of the protective cover 7. At the same time, with the lifting of the third contraction sleeve rod 87, the support rod 91 in the retracting mechanism 9 drives the connecting rod 92 to lift, and finally the protective cover 7 is closed, thereby avoiding accidental damage to the camera 6 when the drone lands.
