Abstract
Description
Technical Field
[0001] This utility model belongs to the field of unmanned helicopter technology, and more specifically, relates to an unmanned helicopter with multiple payload slots. Background Technology
[0002] Unmanned helicopters are unmanned aircraft that can take off and land vertically and hover in the air, either remotely controlled by ground radio or autonomously controlled by the ground. In terms of structure, they belong to rotorcraft, and in terms of function, they belong to vertical take-off and landing aircraft. Heavy-duty unmanned helicopters are one type that can be used to transport heavy materials.
[0003] Currently, most unmanned helicopters have a relatively simple payload structure design, with the payload usually located in the lower middle of the fuselage. This allows for the carrying of cargo at a single payload point, which cannot meet the needs of multi-task and multi-load operations. Especially in heavy-load scenarios or scenarios requiring the coordinated operation of multiple types of equipment, their payload capacity and flexibility are insufficient. Utility Model Content

[0012] As a further improvement of this utility model, the number of side mounting cavities is at least two on each side.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This solution, by setting side-mounted wings with multiple side-mounted cavities on both sides of the middle of the fuselage and setting a cavity with a fixed mounting structure inside the fuselage, enables the unmanned helicopter to carry loads at multiple positions in the middle and sides at the same time, which significantly improves the load-carrying capacity and mission flexibility, and overcomes the limitation of traditional unmanned helicopters that can only carry loads at a single point in the middle.

A fixed frame 142 is fixedly installed on the lower wall of the fixed mounting plate 141, and the fixed frame 142 is used to install hooks for connecting loads. Preferably, a counterweight box can also be installed on the front end of the fixed frame 142 to achieve gravity balance with the drive unit 5 and ensure the stability of the helicopter. The drive unit 5 is installed in the rear cavity, and the fuel tank 6 is installed in the middle of the cavity 14 to ensure the overall balance of the fuselage 1. A base plate 143 is mounted on a fixed frame 142 at the lower middle part of the machine cavity 14, and the base plate 143 is fixedly connected to the fixed frame 142. The base plate 143 is used to connect to the mounting bracket to connect the load to the lower middle part of the machine body 1.

Multiple side mounting cavities 151 are provided on the lower side of the side mounting wings 15, and the side mounting cavities 151 are used to connect the load. In this embodiment, there are two side mounting cavities 151 on one side. It should be noted that the front cavity of the machine cavity 14 can be used to install a counterweight box with a weight similar to that of the drive device 5, and can also place or mount a load with a weight similar to that of the drive device 5; and to ensure the balance of the front and rear cavities, a load can also be connected to the lower end of the rear cavity to ensure the overall balance and stability of the machine body 1.
