Problems solved by technology

[0008] This prior art effectively overcomes the defective of prior art, but still there is room for improvement
Especially the bearing frame of this prior art is made of metal, the self-weight is too large, and the cantilever support structure formed as one with the bearing frame is not suitable for reducing the structural weight
And because the load-bearing frame is placed vertically, the joint surface of the cantilever support structure coincides with the load-bearing surface, which has a great influence on the strength, and the related structures are prone to fatigue damage

Embodiment Construction

[0025] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings. Wherein, the same parts adopt the same reference numerals.

[0026] As described in the background technology, the present invention proposes an improved structure for the deficiencies in the load configuration structure of the oil-powered UAV disclosed in the prior art Chinese patent application 201711089304.X, so that the UAV of the prior art A lighter cantilever bracket can be set in combination with the fuselage bracket of the all-carbon structure. Its connection structure avoids the main displacement path, and can bear greater force with a lighter structural weight. It is lighter in weight but better in strength, and is not prone to fatigue damage.

[0027] Specifically, the cantilever bracket of the present invention is a fur...

Abstract

The invention provides a cantilever support for an oil-driven unmanned aerial vehicle, and the cantilever support is used for supporting a cantilever on an airframe support of an airframe, wherein thecantilever support comprises a base fixedly mounted above the airframe support, a cover plate covering the upper end of the base and being matched with the base to clamp the cantilever and a gasket arranged between the base and the cover plate. The airframe support is of a full-carbon structure so as to be smaller in weight, the cantilever support made of metal is capable of omitting a bearing frame with a large structure and bearing a larger force by relatively light structural weight, light in weight, but better in strength, and fatigue damage is not easy to happen. In addition, the bearingframe is not needed in the application, so that the cantilever support can be supported above the airframe support, a junction surface cannot appear on a vertical position of the cantilever support,the problem of arranging the junction surface on a main force bearing point position is avoided, the up-and-down displacement of the cantilever in a force bearing process cannot be too large, and thus, the risk of member fatigue is reduced.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a multi-rotor oil-powered unmanned aerial vehicle, and in particular to a cantilever bracket for an oil-powered unmanned aerial vehicle. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device. According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. Civilian drones are widely used in aerial photography, agriculture, plant protection, micro-selfies, express delivery, disaster relief, observation of wild animals, monitoring of infectious diseases, surveying and mapping, news reports, power inspections, disaster relief, film and television shooting and other fields. [0003] Existing multi-rotor drones are usually electric drones...
