[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously by onboard computers, either completely or intermittently.

[0003] In the civilian sector, drones combined with industry applications represent the true essential need for drones. Currently, their applications in fields such as aerial photography, agriculture, plant protection, miniature selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying, news reporting, power line inspection, disaster relief, film and television shooting, and creating romance have greatly expanded the uses of drones. Developed countries are also actively expanding industry applications and developing drone technology.

[0004] Currently, drones are being used to transport goods in the express delivery industry. However, the stability of unmanned vehicles for transporting goods is generally poor, and there is a risk that goods may fall. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a cargo loading structure for a logistics drone with high cargo placement stability and the drone itself.

[0006] To solve the above problems, the present invention adopts the following technical solution: A cargo loading structure for a logistics drone includes an intermediate carrier plate and a connecting strip. The connecting strip is arranged in an isosceles trapezoidal shape. The intermediate carrier plate is provided with a guide dovetail groove that matches the connecting strip. One end of the connecting strip is inserted into the guide dovetail groove. The intermediate carrier plate and the connecting strip are slidably connected through the guide dovetail groove. The other end of the connecting strip is provided with an L-shaped corner carrier plate. The L-shaped corner carrier plate is located on the same horizontal plane as the intermediate carrier plate. The L-shaped corner carrier plate is provided with a right-angled upright plate for clamping the cargo box and preventing the cargo box from falling off the intermediate carrier plate. A limiting groove matching the cargo box is formed between the intermediate carrier plate, the connecting strip, and the right-angled upright plate. A connecting frame is provided on the back of the right-angled upright plate. A connecting tube is provided at the end of the connecting frame. A telescopic tube is inserted into the connecting tube. The telescopic tube is movably connected to the connecting tube. A motor and a battery are inserted into the telescopic tube. The output end of the motor is located outside the telescopic tube and is provided with a propeller. The motor and the battery are electrically connected.

[0007] Preferably, the intermediate carrier plate is provided with a guide hole, and the back of the connecting strip is provided with a guide rod. The guide rod and the connecting strip are integrally formed. The end of the guide rod passes through the guide hole and is provided with a support wheel. The guide rod and the support wheel are fixedly connected. The support wheel is in close contact with the intermediate carrier plate. By configuring the guide rod and the support wheel, the connecting strip can have a better support effect and a more stable movement capability.

[0008] Preferably, a reset rubber rope is provided between the intermediate carrier plate and the L-shaped corner carrier plate. The two ends of the reset rubber rope are fixedly connected to the back of the intermediate carrier plate and the L-shaped corner carrier plate, respectively. Four connecting strips and four guide dovetail grooves are provided, and the connecting strips and guide dovetail grooves are distributed in a cross shape. An installation groove is provided in the middle of the intermediate carrier plate, and the guide dovetail grooves are all connected to the installation groove. A pulling mechanism is provided in the installation groove to pull the connecting strips toward the middle of the intermediate carrier plate. By configuring the reset rubber rope and the pulling mechanism, the right-angle upright plate can clamp the cargo box well, preventing the cargo box from easily shifting and improving the stability during operation.

[0009] Preferably, the pulling mechanism includes a column, a first return spring, and a second return spring. The column has a longitudinal through hole and a transverse through hole, with the longitudinal through hole located above the transverse through hole. The first and second return springs pass through the longitudinal and transverse through holes, respectively. A screw hole is provided in the middle of the column, and both the longitudinal and transverse through holes are connected to the screw hole. A limit bolt is screwed into the screw hole, and the limit bolt passes through the first and second return springs in sequence. Each of the first and second return springs has a snap-fit ​​plate at its end. The connecting strip has an embedding groove and a snap-fit ​​groove that matches the snap-fit ​​plate. The embedding groove and the snap-fit ​​groove are connected. The ends of the first and second return springs are embedded in the connecting strip through the embedding groove. The pulling mechanism has a simple structure and is easy to maintain. The embedded structure of the first and second return springs effectively prevents them from being damaged by the cargo, and they are not easily pulled out, resulting in good stability during use.

[0010] Preferably, the inner wall of the connecting pipe is provided with an internal thread, and the outer wall of the telescopic pipe is provided with an external thread that matches the internal thread. The telescopic pipe and the connecting pipe are movably connected through the external and internal threads. The connecting pipe is transparent, and the outer wall of the connecting pipe is provided with a scale. The end of the telescopic pipe is provided with a marking plate, which is located inside the connecting pipe. The beginning of the telescopic pipe is provided with a handle, and the telescopic pipe and the handle are fixedly connected.

It can be effectively used on various boxes with different heights and has good flexibility of use.

[0011] Preferably, the intermediate carrier plate and the connecting strip are provided with weight reduction holes. By providing weight reduction holes, the overall weight can be effectively reduced, thus reducing the burden on the motor during transportation.

[0012] Preferably, a hinge seat is provided on the outer wall of the connecting pipe, and a positioning member for fixing the handle is connected to the hinge seat. The positioning member is hinged to the connecting pipe through the hinge seat. The positioning member is provided with a positioning groove that matches the handle. The handle passes through the positioning groove. The positioning member is provided with a tenon, and the connecting pipe is provided with a mortise that matches the tenon. After the height of the motor is adjusted, the positioning member can be used to position the handle, restricting the movement of the handle and preventing foreign objects from hitting the handle during operation, which would cause the telescopic pipe to rotate, thus effectively improving stability.

[0013] Preferably, one or more right-angle uprights are provided, and tensioners are provided between the right-angle uprights. The right-angle uprights are fixedly connected to the tensioners, and the tensioners are located below the connecting frame. By configuring tensioners, after loading goods, adjacent right-angle uprights can be tightened to prevent displacement of the right-angle uprights, thus providing excellent stability during transportation and making it difficult for the cargo box to fall off.

[0014] Preferably, a support rod is provided at the top of the right-angled upright plate. One end of the support rod is hinged to the right-angled upright plate, and a mounting platform is provided in the middle of the support rod. A gimbal is provided on the mounting platform, and the other end of the support rod is detachably connected to another right-angled upright plate. By configuring the mounting platform and gimbal, it is convenient for staff to install other accessories of the drone, which is very convenient.

[0015] The present invention also provides a drone, including a control system and a cargo loading structure of the above-mentioned logistics drone, wherein the control system is mounted on a mounting platform and a motor is mounted on the gimbal.

[0016] The beneficial effects of this invention are as follows: Because the corner carrier plates are equipped with right-angled uprights for clamping the cargo box and preventing it from falling off the middle carrier plate, and because a limiting groove matching the cargo box is formed between the middle carrier plate, connecting strip, and right-angled uprights, the cargo, after being placed into the limiting groove, is effectively restrained by the limiting effect of the right-angled uprights. The structure of the right-angled uprights fits the cargo box well, providing excellent restraint. The entire cargo placement structure, combined with the drone's frame, effectively prevents cargo from falling off. Each motor has its own battery power supply, allowing for long-term continuous flight. The connecting strips have good mobility, allowing adjustment of their extension according to the size of the cargo box, providing good flexibility and applicability to various cargo boxes of different sizes.
