Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, and a kind of frame riser structure of small-sized single rotor unmanned helicopter is provided.Its structure is simple, is convenient to the connection with base plate and change speed gear box upper plate, and the installation location that still further provides alighting gear is supported.
Technical scheme of the present invention is: the frame riser structure of small-sized single rotor unmanned helicopter, and comprise riser, riser is bar shaped, which is provided with multiple auxiliary hole, and its lower end is provided with base plate connecting bore, and its upper end is provided with change speed gear box lower plate connecting bore.
The further technical scheme of the present invention is: riser lower end is provided with arc notch A; It also comprises contiguous block, and contiguous block one end is provided with arc notch B, and contiguous block is bolted in riser lower end, and arc notch B on it is relative with the arc notch A of riser lower end and form alighting gear mounting hole.
The present invention further technical scheme is: riser is respectively equipped with the positioning groove A embedded for bottom edge and the positioning groove B embedded for panel edges under change speed gear box at the two ends up and down of same end face.
Advantage of the present invention is:
Structure is simple, which is provided with multiple auxiliary hole with expendable weight, it matches with contiguous block and forms alighting gear mounting hole, the installation location providing alighting gear is supported, it is respectively equipped with positioning groove A and positioning groove B at the two ends up and down of same end face, is convenient to location when base plate and change speed gear box upper plate are connected with it.
The depopulated helicopter frame tool that the present invention is assembled has the following advantages:
1, in frame with the cavity installing drive disk assembly, the inner chamber namely between upper cover of speed changing box and change speed gear box lower plate.Without the need to additionally installing change speed gear box, alleviate the overall weight of depopulated helicopter.
2, adopt tower structure, structure is simple, and assembling easily.Arrange upper as can be seen from the position, hole of change speed gear box lower plate, driving engine, one-level speed change, two stage speed change laid out in parallel, improve the integral rigidity of frame, decreases vibrations during flight, improves working stability and the reliability of electronic machine.
Below in conjunction with figure and embodiment the invention will be further described.
