Example

Compared with Example 1, the structure of Example 2 is simpler and lighter, which ensures the stability of the aircraft while ensuring the endurance of the aircraft.

Preferably, as shown in FIG. 2 , in order to reduce the weight of the aircraft, the main panel includes: two carbon fiber plates, the two carbon fiber plates are connected by bolts, and each carbon fiber plate has a rectangular plate in the middle and arc-shaped arms on both sides, the tripod 2 is arranged under the two ends of the arc-shaped arms, and the through groove is opened on the rectangular plate.

Specifically, the two carbon fiber plates are fixed together by a short connecting rod nut 5 to form the main frame of the aircraft, and the drop box is fixed to the middle position of the main panel by a short bolt 3.

Preferably, each of the tripods 2 includes two long carbon fiber plates, which are fixed by hexagonal studs 7. The structure of each tripod is the same, forming four support frames of the aircraft, and the carbon fiber panels of the tripods are arranged on the main panel through slots.

Preferably, in order to ensure neat wiring and facilitate subsequent maintenance of the electronic equipment, a second tray 9 is also included. The first tray 8 and the second tray 9 are both made of carbon fiber. The first tray and the second tray are fixed under the main panel by long connecting rod nuts 6 and long bolts 4 respectively.

Specifically, the electronic device includes: a battery, a power manager, an onboard computer, a radio receiver, a transmitter and a flight control system. The flight control system sends various instructions and processes the data sent back by various components, and sends new instructions after calculation. The power manager converts the standard voltage of the battery into the working voltage of each electrical appliance, and can effectively buffer the fluctuations generated when the battery is powered. Each electrical appliance is powered independently, which reduces the burden of cascade power supply on the electrical appliance and solves the problem of power bottleneck of a certain electrical appliance when cascade power supply is used.

The onboard computer monitors the battery consumption, heat generation, and battery capacity in real time through the management circuit, and promptly changes the current aircraft control strategy to make the flight safer.

When the aircraft is in remote control mode, after the radio receiver receives the command signal from the transmitter to control the drop box, the radio receiver will send the command to the onboard computer to control the loading and unloading of the drop box. The onboard computer encapsulates the control program of the servo response logic under different commands. The onboard computer can control the servo to control the drop box baffle to open completely, and then close the baffle when loading goods. When unloading goods, the baffle can be controlled to open from bottom to top in sequence, so that the goods fall in sequence.

When the aircraft is in autonomous driving state, the onboard computer navigates and controls according to the predetermined waypoint program. After the aircraft reaches the conditions for dropping, the onboard computer autonomously executes the cargo box unloading logic program, allowing the servos to open the lower, middle and upper cargo box baffles in sequence. After the dropping mission is completed, the command to completely close the cargo box baffles is executed.

Preferably, the battery is arranged on the first support plate 8 , and the remaining equipment is arranged on the second support plate 9 .

The above disclosures are only several preferred specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
