[0032] 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. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0033] Refer to Figures 1-5, an embodiment provided by the present utility model: a cargo anti-shake structure for a transport drone transport box, including a transport drone body 1, a mounting frame 2 is fixedly installed at the bottom of the transport drone body 1, a box body 3 is fixedly installed at the top of the mounting frame 2, a rotating rod 4 is horizontally and movably connected to the bottom of the inner wall of the box body 3 through a bearing, and after the rotating rod 4 is driven by a reduction motor 6, it drives a limiting plate 5 to rotate inside the box body 3. A limiting plate 5 is connected to the surface of the rotating rod 4. The limiting plate 5 can divide the inner cavity of the box body 3 into a front cavity and a rear cavity, and can limit the placed goods, so that the goods are not easy to shake inside the box body 3. A sealing frame 21 is connected to the back of the limiting plate 5, the outside of the sealing frame 21 is in contact with the inner wall of the box body 3, a sealing plate 22 is connected inside the box body 3, and the front of the sealing plate 22 is in contact with the back of the sealing frame 21. The sealing frame 21 and the sealing plate 22 can increase the sealing performance between the limiting plate 5 and the box body 3, so that the temperature of the front cavity and the rear cavity of the box body 3 is not easy to flow through. A reduction motor 6 is fixedly installed on the right side of the box body 3. The reduction motor 6 is a power component for driving the rotating rod 4, and the output end of the reduction motor 6 is connected to the right end of the rotating rod 4. Covers 7 are movably connected to the front and back of the box body 3. The covers 7 can seal the front and rear sides of the box body 3 and can drive the pressing rods 8 to press on the goods to limit them. Pressing rods 8 are slidably connected to the inner sides of the covers 7 and the backs of the limiting plates 5. A pressing spring piece 9 is sleeved on the surface of the pressing rod 8. The pressing rod 8 and the pressing spring piece 9 can, when the covers 7 and the limiting plates 5 are about to contact the goods, the pressing rod 8 can contract under the push of the pressing spring piece 9 to adapt to different sizes of the goods and press tightly on the surface of the goods. One ends of the pressing spring pieces 9 are in contact with the inner sides of the covers 7 and the backs of the limiting plates 5, and the other ends of the pressing spring pieces 9 are in contact with the surface of the pressing rod 8. A positioning nut 23 is threadedly connected to the surface of the pressing rod 8. The positioning nut 23 is used to fix the pressing rod 8 so that the pressing rod 8 can be installed on the limiting plate 5 and the cover 7. A rubber head 24 is connected to one end of the pressing rod 8 close to the limiting plate 5. The rubber head 24 can prevent the pressing rod 8 from scratching the goods when contacting the goods, so as to achieve the function of limiting the goods in the box body 3 during transportation and preventing them from shaking. A storage temperature adjustment component is fixedly installed on the box body 3, and fixing components are connected to the front and rear sides of the bottom of the box body 3.

[0034] Refer to Figures 2-4, the storage temperature adjustment component includes an air inlet box 10. A fan 11 is threadedly connected to the top of the air inlet box 10. The air inlet box 10 and the fan 11 can allow external air to enter and then be split through a pipeline into the heating box 12 and the refrigeration box 13 for use. The air inlet box 10 is fixedly installed on the top of the box body 3. The heating box 12 is fixedly communicated with the rear side of the right side of the box body 3, and the refrigeration box 13 is communicated with the front side of the left side of the box body 3. Both the heating box 12 and the refrigeration box 13 are communicated with the air inlet box 10 through pipelines. The pipeline connecting the air inlet box 10 and the refrigeration box 13 is a tee pipe. One end is connected to the air inlet box 10, the other end is connected to the refrigeration box 13, and the last end can blow air onto the surface of the heat sink 16 to accelerate the heat dissipation speed of the heat sink 16, further effectively improving the heat dissipation effect during the use of the refrigeration sheet 15. A heating wire 14 is vertically connected inside the heating box 12. The heating box 12 and the heating wire 14 can heat the air after the pipeline inputs the air into it and then transport it into the rear cavity of the inner cavity of the box body 3, adjusting the internal storage environment to the temperature required by the user. A refrigeration sheet 15 is vertically and fixedly installed inside the refrigeration box 13. After the air flows on its surface, the refrigeration sheet 15 can transport cold air into the front cavity of the inner cavity of the box body 3, reducing the storage environment temperature in the front cavity of the box body 3, so that goods that need to be stored at a lower temperature can also be transported by the unmanned aircraft 1. A heat sink 16 is embedded on the left side of the refrigeration box 13. The right side of the heat sink 16 is in contact with the surface of the refrigeration sheet 15, and the left side of the heat sink 16 extends to the outside of the refrigeration box 13. The heat sink 16 can absorb the heat of the refrigeration sheet 15 and dissipate it to the outside for heat dissipation, thus achieving the effect of being able to separate and adjust the storage of goods into different temperature environments for transportation according to the storage temperature of the goods.

[0035] Referring to Figures 1-3 , the fixing component includes a fixing block 17. The fixing block 17 is connected to the bottom of the box body 3. A screw rod 18 is movably connected to the front of the fixing block 17. The fixing block 17 can support the screw rod 18, enabling the screw rod 18 to stably drive the baffle 19 to rotate, so that after the baffle 19 rotates, it presses on the surface of the cover plate 7, keeping the cover plate 7 and the box body 3 sealed. The baffle 19 is connected to the surface of the screw rod 18, and the baffle 19 is located outside the cover plate 7; A partition plate 20 is connected to the outside of the cover plate 7. The partition plate 20 can block the baffle 19, making the baffle 19 stably press on the cover plate 7 and not easily shift. The shape of the partition plate 20 is L-shaped, improving the stability during the sealing of the cover plate 7 and the box body 3.

[0036] Working principle: When in use, the user first puts the goods to be limited in position into it from the back of the box body 3. First, by rotating the screw rod 18, the screw rod 18 drives the baffle plate 19 to rotate and move out from the cover plate 7 under the support of the fixed block 17, so that the cover plate 7 can be flipped by the user on the box body 3 to open the box body 3. Then, after putting the goods into the rear side of the inner cavity of the box body 3, the cover plate 7 on the back of the box body 3 is flipped down, so that the pressing rod 8 on the cover plate 7 drives the rubber head 24 to press on the goods, causing the pressing rod 8 to squeeze the pressing elastic piece 9 to elastically contract, so that multiple pressing rods 8 press on the goods to limit their position. Then, rotate the screw rod 18 in the reverse direction, so that the screw rod 18 drives the baffle plate 19 to press on the cover plate 7, making the cover plate 7 contact and seal with the box body 3. Then, start the reduction motor 6 to drive the rotating rod 4 and the limiting plate 5 to rotate. After the limiting plate 5 rotates, it drives the sealing frame 21 to press on the sealing plate 22, so that the front cavity and the rear cavity of the inner cavity of the box body 3 are separated to store goods. And the pressing rods 8 on the limiting plate 5 are the same as above, and can press on the goods to tightly press and limit the goods to prevent them from shaking. Then, when the cover plate 7 on the front cavity of the box body 3 for placing goods is opened and the goods are placed in it and then closed, the pressing rods 8 on it slide in the cover plate 7 and contract according to the different sizes of the goods, so that the goods are stably limited in the box body 3 during transportation, preventing the goods from being unstable during transportation, thereby achieving the function of limiting the goods in the box body 3 during transportation to prevent them from shaking. Moreover, the limiting plate 5 can divide the inner cavity of the box body 3 into two storage environments. The goods that need to be stored in a lower temperature environment are placed in the front cavity of the box body 3, and the hotter and normal temperature goods are placed in the rear cavity of the box body 3. When the fan 11 is started and the refrigerating sheet 15 is started, air flows through the surface of the refrigerating sheet 15 through the pipeline and then enters the front cavity of the box body 3, making the temperature of the storage environment in the front cavity of the box body 3 become lower. And when the heating wire 14 in the heating box 12 is started, air enters the heating box 12 through the pipeline and is heated by the heating wire 14 and then enters the rear cavity of the box body 3, making the temperature of its storage environment rise. It is convenient for the user to temporarily store the goods in the box body 3 according to the goods storage environment for transportation, and improves the diversity of the goods transported by the unmanned transport aircraft 1.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
