[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: an unmanned aerial photography device, including a rotor UAV body 1 and a camera 2, the rotor UAV body 1 is provided with four rotors for flying, the rotor UAV body 1 is provided with an organism 11, and the organism 11 is a component of the rotor UAV body 1 for power supply and flight control.

[0024] In the present technical solution, a suspension frame 3 is fixedly connected to the bottom of the body 11, and a gimbal 4 is arranged at the bottom of the suspension frame 3. The gimbal 4 adopts a universally movable control console commonly used in the prior art. A camera 2 is connected to the bottom of the gimbal 4. During the specific implementation, the universal seat on the gimbal 4 and the camera 2 are fixedly connected. When the rotor UAV body 1 is flying, the gimbal 4 can control the camera 2 to take images in all directions.

[0025] Furthermore, two struts 5 are provided at the bottom of the body 11, which are located on both sides of the gimbal 4. The rods of the struts 5 are connected to the suspension frame 3 for vertical rotation. In specific implementation, the suspension frame 3 is preferably a slot frame, and the two vertical plates 31 on the suspension frame 3 are provided with clearance holes 311. The two sides of the struts 5 are welded with connecting shafts 51 that are rotatably connected to the two side walls of the clearance holes 311. The struts 5 play the role of landing support for the rotor UAV body 1, and the suspension frame 3 is provided with a control group assembly 6 for controlling the synchronous opposite and reverse rotation of the two struts 5.

[0026] Specifically, the control group combination 6 includes an electric push rod 61 and a torsion spring 62. The connecting shaft 51 is connected to the give way hole 311 through the torsion spring 62. Under the action of the torsion spring 62, the support rod 5 has a tendency to swing downward to a vertical state. The electric push rod 61 is fixedly arranged at the bottom of the suspension frame 3 and its output shaft is fixedly connected with a push plate 611. The two ends of the push plate 611 are respectively abutted against one side of the adjacent support rod 5. Therefore, when the push plate 611 moves upward, the two support rods 5 will be pushed to swing downward, and vice versa, the two support rods 5 will swing upward under the action of the torsion spring 62.

[0027] When the rotor UAV body 1 is flying, the two struts 5 are approximately in a horizontal state, which can reduce wind resistance. When the rotor UAV body 1 lands, the struts 5 are controlled to tilt in the vertical direction, and the struts 5 can support the entire rotor UAV body 1.

[0028] Furthermore, a shock-absorbing rod 7 is provided at one end of the support rod 5 away from the suspension frame 3, and the action end of the shock-absorbing rod 7 is fixedly connected to the support plate 8. In specific implementation, it is preferred that the shock-absorbing rod 7 includes a sleeve 71, a support shaft 72 and a shock-absorbing spring 73. One end of the support shaft 72 is sleeved in the sleeve 71, and the shock-absorbing spring 73 is arranged in the sleeve 71 and one end is against one end of the support shaft 72. One end of the sleeve 71 is fixedly connected to one end of the support rod 5. A connecting plate 82 is welded to one side of the support plate 8, and one end of the connecting plate 82 is fixedly connected to the other end of the support shaft 72. When the rotor UAV body 1 lands, the support plate 8 contacts the ground, and the shock-absorbing rod 7 plays a buffering role, thereby buffering and protecting the camera 2.

[0029] Furthermore, both ends of the support plate 8 are fixedly connected with protective plates 81 bent toward the suspension frame 3. The protective plates 81 function to provide peripheral protection for the rotor. That is to say, when the support rod 5 is in a horizontal state, the protective plates 81 are located on the outside of the rotor in the horizontal direction.

[0030] In this embodiment, a protective net 811 used in conjunction with the rotor on the rotor UAV body 1 is fixedly connected to one side of the protective plate 81. The function of the protective net 811 is to reduce wind resistance and at the same time increase the range of protection for the rotor.

[0031] In this embodiment, a protective rubber pad 83 is bonded to the back of the support plate 8. When the support plate 8 contacts the ground, the protective rubber pad 83 acts as a first buffer component to reduce contact impact force and impact noise.

[0032] Working principle: when it is necessary to fly, start the rotor UAV body 1, the body 11 starts to rise, then start the electric push rod 61, the electric push rod 61 returns, the push plate 611 moves downward, and the two support rods 5 are swung up to a horizontal state under the action of the torsion spring 62. At this time, the protective plate 81 will move to the outside of the rotor, and then control the rotor UAV body 1 to fly at high altitude. Finally, control the movement of the gimbal 4 to obtain images in any range. When it is necessary to land, control the push plate 611 to move upward, and the two support rods 5 are pushed to swing down. When the support plate 8 contacts the ground, the protective rubber pad 83 and the shock absorbing rod 7 can effectively buffer the landing impact force, thereby effectively protecting the camera 2.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
