Embodiment 1

[0026] see Figure 4 , the separator 200 in this embodiment is a grid structure 220 , and the grid structure 220 divides the internal space of the fuel tank to form a plurality of vertically arranged cavities 300 . In practical applications, the upper and lower ends of each cavity are opened, and the bottom of each cavity is connected to the liquid outlet (in practical applications, the top of the separator 200 is slightly lower than the tank 100 to facilitate filling gasoline into the tank; the bottom of the separator 200 is set There is a support or gasket structure, and the function of the support or gasket structure is to separate the bottom of the partition 200 from the bottom of the box body 100, so as to prevent the bottom of each cavity from being in close contact with the bottom of the partition 200 and the bottom of the box 100. are closed, so that the cavities cannot communicate with the liquid outlet). With the fuel tank structure of this embodiment, when the fuel...

Embodiment 2

[0030] The fuel tank structure of this embodiment is basically the same as that of Embodiment 1, the difference is that see Figure 5 , the divider of the present embodiment adopts a plurality of independently arranged tubular bodies 210, and each tubular body 210 is vertically arranged and inserted into the box body 100 to separate the inside of the box body 100 to form a plurality of cavities 300; the bottom of each tubular body 210 communicates with the Liquid outlet. The separator of this structure is easier to process and lower in cost, and the independently arranged tubular body structure can flexibly fill oil tank structures of different sizes, and the arrangement is more flexible.

[0031] In practical applications, the shape of the tubular body 210 is preferably a regular hexagonal tubular body (see Figure 5 ), the regular hexagonal tubular body is more convenient and simple to fill, and the fit between the tubular bodies is tighter, the whole structure is more stab...

Embodiment 3

[0034] This embodiment is to optimize the bottom structure of the cavity in embodiment 1 or 2. A flow-blocking structure is provided at the bottom of the cavity to prevent liquid from flowing from the bottom of the cavity into the cavity. The cavity passes through the flow-blocking structure. The structure communicates with the liquid outlet.

[0035] In this example, see Figure 6 , the blocking structure is selected as the small hole structure 410 . The setting of the small hole structure greatly reduces the liquid circulation velocity at the bottom of each cavity 300. When the fuel tank is tilted (or when the motion state changes suddenly), the center of gravity of the fuel tank changes greatly due to the slow flow of liquid at the bottom of each cavity 300. Slow, can basically guarantee as image 3 status shown.

[0036] When the fuel tank structure of this embodiment is tilted, its center of gravity offset is small, and as time goes by, its center of gravity changes sl...

Abstract

The invention discloses an oil tank structure and an unmanned aerial vehicle. The oil tank structure comprises a tank, wherein a liquid outlet is formed in the bottom of the tank, separators are arranged in the tank and divide the tank into a plurality of vertical cavities, and bottoms of the cavities communicate with the liquid outlet. According to the novel oil tank structure, when the motion state of the oil tank is changed, a liquid in the oil tank can be effectively prevented from flowing, and accordingly, the change of the gravity center of the oil tank is effectively prevented. For the unmanned aerial vehicle manufactured with the oil tank structure, the flying stability of the unmanned aerial vehicle is improved.

Description

technical field [0001] The invention relates to a fuel tank structure, in particular to a fuel tank structure suitable for unmanned aerial vehicles and an unmanned aerial vehicle using the fuel tank structure. Background technique [0002] In practical applications, UAVs need to maintain a stable state in the air (including stable hovering or flying), and the adjustment or control of its center of gravity is very important. Traditional UAVs generally use gasoline or batteries as the power source. For UAVs that use gasoline as the power source, a fuel tank is generally arranged in the fuselage, and gasoline is housed in the fuel tank. When the drone tilts slightly, the gasoline level in the fuel tank also tilts, and the center of gravity of the gasoline changes, which directly affects the change of the center of gravity of the drone, thus causing the drone to be unstable in the air. Especially during the rapid flight and avoidance process of the UAV, the liquid inside the fu...
