Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0022] like Figs. 1 to 4 As shown, a takeoff and landing protection device for an aerial photography drone is installed on the drone body 1. The device includes a first protective plate 2 and a second protective plate 3 disposed on the outer side of the drone body 1. The first protective plate 2 and the second protective plate 3 are symmetrical to each other. Movable rods 4 are provided on opposite sidewalls of the first protective plate 2 and the second protective plate 3. A drive assembly is provided at the bottom of the drone body 1. The drive assembly is used to drive the first protective plate 2 and the second protective plate 3 to rotate via the movable rods. When the drone body 1 descends, the drive assembly can control the first protective plate 2 and the second protective plate 3 to rotate 90 degrees to the bottom of the drone body 1. When the drone body 1 takes off, the drive assembly can control the first protective plate 2 and the second protective plate 3 to rotate 90 degrees to protect the propellers on both sides of the drone body 1.

[0023] In a specific embodiment, a rectangular slot 5 is provided at the bottom of the aerial photography drone body 1. Slide grooves 6 are provided on both opposite side walls of the inner cavity of the rectangular slot 5. The two slide grooves 6 are symmetrical to each other, and slide rods 7 are slidably mounted inside the inner cavities of both slide grooves 6. In this configuration, when the electric motor 8 is running, it can drive the threaded rod 9 to rotate, thereby causing the threaded sleeve 10 engaged on the threaded rod 9 to move vertically up and down with the assistance of the slide grooves 6 and slide rods 7.

[0024] Furthermore, the drive assembly includes an electric motor 8, which is disposed on the inner wall of the rectangular slot 5. A threaded rod 9 is provided at the output end of the electric motor 8, and a threaded sleeve 10 is engaged with the threaded rod 9. Slide rods 7 are connected to both sides of the threaded sleeve 10. In this configuration, the installation position and components of the drive assembly are determined, ensuring that the threaded sleeve 10 can vertically move the first protective plate 2 and the second protective plate 3 to rotate.

[0025] Furthermore, two symmetrical connecting rods 11 are fixedly connected to the bottom of the threaded sleeve 10, and a fixing plate 12 is provided at the end of the two connecting rods 11 away from the threaded sleeve 10. In this configuration, the installation position of the fixing plate 12 is determined to ensure that when the fixing plate 12 moves vertically downward, it can squeeze the first flip plate 16 and the second flip plate 17 to flip them.

[0026] Furthermore, the bottom of the aerial drone body 1 has fixed blocks 13 on both sides of the rectangular slot 5. The fixed blocks 13 are rotatably connected to rotating rods 14, and the rotating rods 14 are fixedly connected to movable rods 4. In this configuration, it is ensured that when the rotating rods 14 rotate, they can drive the first protective plate 2 and the second protective plate 3 to rotate through the movable rods 4.

[0027] Furthermore, a first flip plate 16 and a second flip plate 17 are respectively fixedly installed on the rotating rods 14 on both sides of the rectangular slot 5. The first flip plate 16 and the second flip plate 17 are equipped with torsion springs 15, which are sleeved on the rotating rods 14, with one end of the torsion spring 15 mounted on the fixed block 13. In this configuration, when the drone body 1 takes off, the electric motor 8 will run, thus reversing the above steps. Therefore, the first protective plate 2 and the second protective plate 3 can be flipped with the assistance of the torsion springs installed on the first flip plate 16 and the second flip plate 17, allowing the first protective plate 2 and the second protective plate 3 to be located outside the drone body 1, thereby ensuring protection of the drone body 1's propellers during takeoff.

[0028] The implementation principle of the aerial photography drone take-off and landing protection device in this embodiment is as follows: First, when the aerial photography drone body 1 needs to land, the electric motor 8 is controlled to run. Therefore, the electric motor 8 can drive the threaded rod 9 to rotate, thereby driving the threaded sleeve 10 engaged on the threaded rod 9 to move vertically up and down with the assistance of the sliding groove 6 and the sliding rod 7. When the threaded sleeve 10 moves vertically upward, it can drive the fixed plate 12 to move vertically downward through the connecting rod 11. When the fixed plate 12 moves vertically upward, the first flip plate 16 and the second flip plate 17 can flip with the assistance of the torsion spring 15 and the rotating rod 14, that is, the rotating rod 14 rotates 90 degrees. When the rotating rod 14 rotates 90 degrees, it can drive the four movable rods 4 to rotate 90 degrees respectively. Therefore, the first protective plate 2 and the second protective plate 3 can flip down, so that when the aerial photography drone body 1 lands, the first protective plate 2 and the second protective plate 3 can be located at the bottom, thereby playing a supporting role (because the first flip plate 16 and the second flip plate 17 are symmetrical to each other).

[0029] When the drone body 1 takes off, the electric motor 8 will run, thus reversing the above steps. This allows the first protective plate 2 and the second protective plate 3 to be located outside the drone body 1, thereby ensuring that the propellers of the drone body 1 can be protected during takeoff.
