Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0026] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0027] An unmanned aircraft applicable to the delivery of rescue supplies, as Figure 1-8 shown, includes a UAV body 1 and a storage box 2. The storage box 2 is installed at the bottom of the UAV body 1. A positioning module 8 is installed below the frame of the UAV body 1. The positioning module 8 is composed of video acquisition, ranging and positioning, and attitude measurement, and accurately locates information such as the position and height of the UAV body 1.

[0028] The inner wall of the storage box 2 is provided with a rescue supply box 3 through a fixing mechanism. The fixing mechanism includes an electromagnetic lock 5. The electromagnetic lock 5 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 at the top of the rescue supply box 3. When it is necessary to transport the rescue supply box 3, the storage box 2 is sleeved outside the rescue supply 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 supply box 3 inside 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 realize the fixation of the rescue supply box 3.

[0029] Furthermore, when the storage box 2 is sleeved outside the rescue supply box 3, it needs to be positioned by a positioning mechanism. The positioning component is an infrared positioning sensor 7. The infrared positioning sensor 7 is installed on the inner top wall of the storage box 2. A positioning block 6 is provided at the top of the rescue supply box 3, and the positioning block 6 corresponds to the infrared positioning sensor 7. The position of the rescue supply box 3 and the storage box 2 is determined by positioning with the infrared positioning sensor 7 and the positioning block 6. At this time, the UAV body 1 can directly descend to sleeve the storage box 2 outside the rescue supply box 3, effectively preventing the lifting of rescue supplies from affecting the flight of the UAV in areas with many trees.

[0030] When the rescue supply box 3 is taken away by the UAV body 1, the UAV body 1 flies to a designated position and is ready to drop the rescue supply box 3 after adjusting the height. An annular seat 11 is installed in the middle of the bottom of the rescue supply box 3. A ball 13 is rotatably arranged in the circumferential groove on the outer wall of the annular seat 11. Guide plates 16 are rotatably arranged on the side walls of the rescue supply box 3. The guide plates 16 are controlled to rotate by a driving mechanism. The driving mechanism includes an electric push rod 15. The output end of the electric push rod 15 is rotatably connected to one side of the guide plate 16 through a connecting seat. An infrared sensor 12 is arranged in a circle on the outer wall of the annular seat 11. The rescue supply 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 Figure 8 shown. When the rescue supply box 3 is tilted, the ball 13 leaves the deep part of the 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 attitude of the rescue supply box 3. When it is found that the rescue supply box 3 is deflected, the deflected direction is the direction where the ball 13 is located. At this time, the electric push rod 15 drives the guide plate 16 to rotate. By continuously rotating the guide plate 16, the attitude of the rescue supply box 3 is adjusted to keep it falling in a horizontal state. When the rescue supply box 3 is in a horizontal state, the ball 13 is located in the deep part of the groove of the annular seat 11. At this time, the infrared sensor 12 does not detect a change in the distance of the ball 13, and the position of the guide plate 16 does not change.

[0031] A mounting base 9 is provided at the bottom of the rescue supply box 3, and the airbag 10 is installed inside the mounting base 9. When the rescue supply box 3 lands directly, the impact force will damage the rescue supply box 3. Therefore, the airbag 10 protects the rescue supply box 3. When the rescue supply box 3 touches the ground, the buffer mechanism first buffers and protects the rescue supply box 3. The buffer mechanism includes a first buffer spring 17, which is arranged at the four corners of the bottom of the rescue supply box 3. A positioning shell 21 is arranged inside the first buffer spring 17 at the bottom of the rescue supply box 3. A second buffer spring 20 is arranged on the inner wall of the positioning shell 21. One end of the second buffer spring 20 is provided with a connecting block 19. An activity shell 18 is movably arranged on the outer wall of the positioning shell 21. That is, after the rescue supply box 3 lands, the first buffer spring 17 and the second buffer spring 20 buffer the impact force in sequence. When the first buffer spring 17 buffers to the limit, the activity shell 18 approaches the bottom of the rescue supply box 3. At this time, the connecting block 19 contacts the fixed block 22, and the second buffer spring 20 buffers the impact force;

[0032] When the buffer of the second buffer spring 20 reaches the limit, the fixed block 22 is connected to the triggering mechanism of the airbag 10, and the airbag 10 starts to expand with air, completing the last layer of protection for the rescue supply box 3. The triggering mechanism of the airbag 10 can be a contact switch. When the fixed block 22 is impacted and applies pressure to the switch, the airbag 10 opens for corresponding inflation work. The inflation component of the airbag 10 is prior art, so no specific description is given to it.

[0033] A storage battery 14 is installed at the bottom of the rescue supply box 3. The storage battery 14 supplies power to the electrical components on the rescue supply box 3. And the rescue supply box 3 is part of a drone. After the transportation is completed, it can also be recycled for subsequent reuse.

[0034] Although the embodiments of the present invention have been shown and described, this specific embodiment is only an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
