Body supporting assembly for four-axis unmanned aircraft

Abstract

The invention discloses a body supporting assembly for a four-axis unmanned aircraft. Two positioning frames (17) parallel to each other are arranged at the position, close to an equipment bin (13), inside each cantilever (14); a bottom plate (18) is inserted and fixed into the two positioning frames (17); an electronic speed regulator (19) is arranged on each bottom plate (18); a landing gear (1) comprises a left bottom tube (3) and a right bottom tube (3) which are parallel to each other; supporting tubes (4) are welded at the front and rear parts of each bottom tube (3); a supporting plate (5) is fixed at the top of each supporting tube (4) and is fixedly supported at the position, close to the root, of the bottom surface of the corresponding cantilever (14). The body supporting assembly is simple in structure, convenient and quick to assemble and disassemble, excellent in firmness and high in stability. By arranging the electronic speed regulators inside the cantilevers, the spaces of the cantilevers are fully utilized, and the electronic speed regulators are quite convenient and quick to assemble and disassemble.

Description

technical field [0001] The invention belongs to the technical field of agricultural aircraft, and in particular relates to a fuselage support assembly of a four-axis aircraft. Background technique [0002] With the development of society and the advancement of science and technology, large-scale spraying of pesticides and fertilization on farmland are gradually completed by unmanned aerial vehicles. The landing gear of the existing four-axis unmanned aerial vehicle is supported on the bottom of the fuselage equipment compartment by four quick-change devices. The stability of the fuselage is poor. Not only that, but the contact surfaces between the four quick-change devices and the fuselage are small, and the reliability of the connection with the fuselage is not good. In addition, the electronic governor is generally arranged in the equipment compartment. This arrangement not only greatly occupies the space of the equipment compartment, but also affects the arrangement of ...

Problems solved by technology

The landing gear of the existing four-axis unmanned aerial vehicle is supported on the bottom of the fuselage equipment compartment by four quick-change devices. The stability of the fuselage is poor

Not only that, but the contact surface between the four quick-change devices and the fuselage is small, and the reliability of the connection with the fuselage is not good

In addition, the electronic governor is generally arranged in the equipment cabin. This arrangement not only greatly occupies the space of the equipment cabin, but also affects the arrangement of other components in the equipment cabin; it is also extremely inconvenient to disassemble and assemble, and the performance is not guaranteed.
