Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a small UAV for transporting goods. Background Technology

[0002] A drone is an unmanned flying device controlled by radio remote control equipment and its own program control device. It is commonly used for aerial photography, monitoring and management, emergency rescue, and transporting goods. Traditionally, drones used for transporting goods often employ an external sling structure, that is, a rope is installed at the bottom of the drone to tie the cargo. The cargo is then connected by the rope to achieve the transport of the cargo. However, this structure also lowers the overall center of gravity of the drone, increasing the workload of the controller to compensate for the balance of the fuselage during flight, and affecting the stability of the drone's flight. Utility Model Content

[0003] To overcome the shortcomings of the prior art, the technical solution adopted by this utility model is as follows: a small cargo transport drone, including a fixed frame, a protective shell fitted over the fixed frame, and an internal combustion engine, fuel tank, propeller assembly, controller, camera, adapter, and cargo box mounted on the fixed frame. The fixed frame has fuel tanks connected to both sides to provide fuel for the internal combustion engine. The output end of the internal combustion engine is rotatably connected to a propeller assembly for providing lift. The front end of the fixed frame has a controller for controlling the operation of the internal combustion engine and a camera electrically connected to the controller. The bottom of the fixed frame has a connecting rod for connecting to the adapter. The cargo box is connected to both sides of the protective shell through the adapter.

[0004] Using the above technical solution, this utility model is mainly powered by an internal combustion engine and can travel for 400km. The fuel tank has an inlet pipe extending to the outside of the protective shell, and the bottom of the fuel tank has a fuel delivery pipe connected to the internal combustion engine. The fuel in the tank is easily fed into the internal combustion engine by gravity. The controller is used to control the operation of the internal combustion engine, the propeller assembly and the camera. Each side of the fuselage is equipped with a 70L cargo box, with an effective total load of 200kg, which enables the rapid transportation of important items. Compared with the traditional externally mounted structure, the overall center of gravity of the drone is shifted upward, which is beneficial to the control of the drone's balance during flight.

[0005] The present invention is further configured such that the fixing frame has a main frame, an upper frame and a side frame connected to the main frame, the internal combustion engine and the controller are fixedly connected to the inside of the main frame, the fuel tank is located on both sides of the upper frame, the blade assembly is connected to the top of the fixing frame through the upper frame, and the camera is connected to the front of the fixing frame through the side frame.

[0006] Furthermore, the main frame includes vertical and horizontal bars welded into a cuboid frame structure. The two ends of the horizontal bars are provided with extension tubes for mounting the cargo box, and the extension tubes are provided with through holes for fixing the connecting rods.

[0007] Using the above technical solution, the fixing frame is made of stainless steel pipes connected by welding or sleeves. The main frame is a cuboid structure made of overlapping stainless steel pipes. The two longer crossbars at the bottom of the main frame naturally form extension tubes. The overall structure is simple and reasonably designed.

[0008] The present invention is further configured such that the adapter seat has connecting holes on both sides, one end of the connecting rod has a stepped portion for abutting against the outer side of the adapter seat, and the other end passes through the connecting hole and is snapped into the extension tube.

[0009] Furthermore, the cargo box includes a box body and a box cover hinged to the box body. The bottom of the box body is provided with a groove for installing an adapter seat and a stud portion provided in the groove. The adapter seat is provided with an inner cavity for accommodating the stud portion, and the inner cavity is provided with threaded holes coaxially distributed with the stud portion.

[0010] Furthermore, a rubber pad is provided on the inner side of the box.

[0011] Using the above technical solution, when installing the cargo box, the connecting rod is passed through the adapter and fitted into the extension tube, and the bolts are passed through the through hole to fix the two. Then, the adapter is inserted into the sliding groove of the box until the rubber pad is attached to the protective shell. At this time, the stud and the threaded hole are coaxially distributed. The adapter is then fixed on the adapter with screws. The overall structure is simple and easy to install.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The two sides of the fixed frame are detachably connected to cargo boxes for loading goods via connecting rods. Compared with the traditional external hanging structure, the overall center of gravity of the drone is shifted upward, which is conducive to the control of the drone's body balance during flight, making the drone more sensitive to control and more stable in flight.
