Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and more specifically to an external battery box for unmanned aerial vehicles. Background Art

[0002] Unmanned aircraft, referred to as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices. Drones are actually a general term for unmanned aerial vehicles. From a technical perspective, they can be divided into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airships, unmanned helicopters, unmanned multi-rotor aircraft, unmanned paragliders, etc. In the fields of rescue, agriculture and civil use, unmanned multi-rotor aircraft are the main type.

[0003] The Chinese utility model patent "An external drone battery box" with application number 201920855158.5 provides a battery box, which passes the two power cords of the drone through the through holes and perforations, and uses the sockets on the cross-shaped fixing block to plug and cooperate with the limit columns to fix the power cords to prevent the power cords from shaking and falling off during the flight of the drone, causing the drone to crash. In addition, when taking the battery, you only need to use the notch to open the two baffles relative to each other, which solves the problem of the drone battery box being prone to power cord shaking and inconvenient to take the battery.

[0004] However, this technical solution also has certain defects. The battery installed in the battery box is the main power supply device of the drone. It just converts the original built-in battery into an external one. The technical problem solved is the shaking of the power cord and the inconvenience of taking the battery. However, there is a problem with drones in the rescue or civilian fields, that is, the battery life. Due to the limitations of the development of the battery field, in order to keep the battery volume and weight within the limit, the actual capacity of the battery is limited, and the battery life of the drone cannot be enhanced. At this time, in order to respond to emergencies, it is necessary to frequently replace or charge the battery, but each time the battery is replaced, the drone needs to fly back from the disaster relief site to the control point for landing, which greatly wastes time.

[0025] Embodiment 1 of the present utility model is as follows:

[0026] The external battery box of a drone includes a bottom plate 2, two fixing plates 1 and twelve connecting columns 3. The fixing plate 1 is a rectangular ring structure with a rectangular opening in the middle. Twelve through holes 6 are evenly arranged on the edge of the fixing plate 1, corresponding to the number of the connecting columns 3.

[0027] The fixing plate 1 is provided with five through holes 6 at the left and right ends respectively, and one through hole 6 is provided at the middle of the upper and lower ends respectively.

[0028] Two fixing plates 1 and a bottom plate 2 are arranged in sequence from top to bottom, and the two fixing plates 1 are connected by eight connecting columns 3 .

[0029] Between the two fixing plates 1, three connecting columns 3 are arranged at intervals at the left and right ends, a through hole 6 is left between adjacent connecting columns 3, and a connecting column 3 is arranged in the middle of the upper and lower ends to form a stable and strong frame structure.

[0030] The fixing plate 1 and the bottom plate 2 at the bottom are connected by four connecting columns 3, and the four connecting columns 3 are connected to the through holes 6 at both ends of the fixing plate 1. After the battery is installed, the center is located in the middle of the entire frame structure, which can maintain stability.

[0031] The diameter of the connecting column 3 is the same as that of the nut 33, and both are larger than the diameter of the through hole 6. A thread hole 31 is provided at the end of the connecting column 3, and a bolt 32 is connected in a meshing manner in the thread hole 31. The connecting column 3 is arranged at a position corresponding to the through hole 6 and connected by the bolt 32, so that the adjacent fixing plates 1 can be connected to form a three-dimensional structure.
