[0018] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0019] The following describes an embodiment of the present invention based on its overall structure.

[0020] An unmanned aircraft suitable for delivering relief supplies, such as Figure 1-8 As shown, it includes a drone body 1 and a storage box 2. The storage box 2 is installed at the bottom of the drone body 1. A positioning module 8 is installed under the frame of the drone body 1. The positioning module 8 is composed of video acquisition, ranging positioning, and attitude measurement to accurately locate the position, height and other information of the drone body 1.

[0021] The inner wall of the storage box 2 is provided with a rescue material box 3 through a fixing mechanism, and the fixing mechanism includes an electromagnetic lock 5, which is installed on the inner top wall of the storage box 2, and a positioning hole 4 corresponding to the electromagnetic lock 5 is opened on the top of the rescue material box 3. When the rescue material box 3 needs to be transported, the storage box 2 is put on the outside of the rescue material box 3. At this time, the electromagnetic lock 5 is inserted into the positioning hole 4, and the electromagnetic lock 5 is started. The electromagnetic lock 5 fixes the rescue material box 3 to the inside of the storage box 2. The electromagnetic lock 5 is an electromagnet assembly. By inserting the electromagnet into the positioning hole 4, the metal inside the positioning hole 4 is adsorbed to achieve the fixation of the rescue material box 3.

[0022] Furthermore, the storage box 2 set on the outside of the rescue material box 3 needs to be positioned by a positioning mechanism. The positioning component is an infrared positioning sensor 7, and the infrared positioning sensor 7 is installed on the inner top wall of the storage box 2. A positioning block 6 is set on the top of the rescue material box 3, and the positioning block 6 corresponds to the infrared positioning sensor 7. The infrared positioning sensor 7 and the positioning block 6 are used for positioning to realize the position determination of the rescue material box 3 and the storage box 2. At this time, the drone body 1 can directly fall to realize the storage box 2 set on the outside of the rescue material box 3, which effectively prevents the lifting of rescue materials from encountering areas with many trees, which will affect the flight of the drone.

[0023] When the rescue material box 3 is taken away by the drone body 1, the drone body 1 flies to the designated position, and is ready to drop the rescue material box 3 after adjusting the height. An annular seat 11 is installed in the middle of the bottom of the rescue material box 3, and a ball 13 is rolled inside the circumferential groove of the outer wall of the annular seat 11. The side walls of the rescue material box 3 are all rotatably provided with a guide plate 16, and the guide plate 16 is controlled to rotate by a driving mechanism. The driving mechanism includes an electric push rod 15, and the output end of the electric push rod 15 is rotatably connected to one side of the guide plate 16 through a connecting seat. A circle of infrared sensors 12 are provided on the outer wall of the annular seat 11. The rescue material box 3 falls from the air, and the ball 13 moves around the annular seat 11. The internal structure of the annular seat 11 is as shown in FIG. Figure 8 As shown, when the rescue material box 3 is tilted, the ball 13 leaves the deep groove of the annular seat 11, and the position of the ball 13 is detected in cooperation with the infrared sensor 12, thereby detecting the falling posture of the rescue material box 3. When it is found that the rescue material box 3 is offset, the deflection direction is the direction of the ball 13. At this time, the electric push rod 15 drives the guide plate 16 to rotate. Through the continuous rotation of the guide plate 16, the posture of the rescue material box 3 is adjusted to keep it in a horizontal state. When the rescue material box 3 is in a horizontal state, the ball 13 is located in the deep groove of the annular seat 11. At this time, the infrared sensor 12 does not detect the distance change of the ball 13, and the position of the guide plate 16 does not change.

[0024] A mounting seat 9 is provided at the bottom of the rescue material box 3, and an airbag 10 is installed inside the mounting seat 9. When the rescue material box 3 falls directly to the ground, the impact force will damage the rescue material box 3, so the rescue material box 3 is protected by the airbag 10. When the rescue material box 3 contacts the ground, the buffer mechanism first buffers and protects the rescue material box 3. The buffer mechanism includes a first buffer spring 17. The first buffer spring 17 is arranged at the four corners of the bottom of the rescue material box 3. The bottom of the rescue material box 3 is located inside the first buffer spring 17 and a positioning shell 21 is provided. The inner wall of the positioning shell 21 is provided with a second buffer spring 20. A connecting block 19 is provided at one end of the second buffer spring 20. A movable shell 18 is movably provided on the outer wall of the positioning shell 21. That is, after the rescue material box 3 falls to the ground, the first buffer spring 17 and the second buffer spring 20 buffer the impact force in turn. When the first buffer spring 17 buffers to the limit, the movable shell 18 approaches the bottom of the rescue material box 3. At this time, the connecting block 19 contacts the fixed block 22, and the impact force is buffered by the second buffer spring 20. When the buffering of the second buffer spring 20 reaches its limit, the fixed block 22 is connected to the trigger mechanism of the airbag 10, and the airbag 10 begins to expand with air, completing the last layer of protection for the rescue material box 3. The trigger mechanism of the airbag 10 can be a contact switch. When the fixed block 22 is impacted and pressure is applied to the switch, the airbag 10 opens and performs corresponding inflation work. The inflation component of the airbag 10 is prior art, so it is not described in detail.

[0025] A battery 14 is installed at the bottom of the rescue material box 3, and the battery 14 supplies power to the electrical components on the rescue material box 3. In addition, as a part of the drone, the rescue material box 3 can be recovered after the transportation is completed for subsequent reuse.

[0026] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
