Chain-transmission modular graded acceleration electric ejector of small-sized unmanned aerial vehicle and design method of chain-transmission modular graded acceleration electric ejector

Abstract

The invention discloses a chain-transmission modular graded acceleration electric ejector of a small-sized unmanned aerial vehicle and a design method of the chain-transmission modular graded acceleration electric ejector. The chain-transmission modular graded acceleration electric ejector of the small-sized unmanned aerial vehicle comprises an ejector body, a base device, a power device, a suspension device, a safety protection device, a stop block, a buckle plate, a release mechanism, a locking mechanism, a sliding block and a limiting block. The design method of the chain-transmission modular graded acceleration electric ejector of the small-sized unmanned aerial vehicle includes the steps that 1, overall design of the ejector is conducted, wherein the ejector comprises the base structure, the power device, the suspension device and the safety protection device; 2, selection of the types of a direct-current motor, a chain transmission device, a guide rail, an ejector rack, the locking mechanism, the release mechanism, a front support, a rear support and a speed reduction damper is completed; and 3, three-dimension solid modeling is carried out on the ejector through the computer aided three-dimensional interactive application (CATIA). By means of the chain-transmission modular graded acceleration electric ejector of the small-sized unmanned aerial vehicle and the design method of the chain-transmission modular graded acceleration electric ejector, graded acceleration of the skating process of the guide rail of the unmanned aerial vehicle can be achieved, and through the detachable modular design, assembling and disassembling are facilitated, and transportation and maintenance are also facilitated.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles (UAVs), in particular to a design method for a small unmanned aerial vehicle (UAV) chain drive modularized step-by-step acceleration electric catapult. Background technique [0002] The use of small drones in the civilian field is becoming more and more extensive, and the impact is becoming more and more far-reaching. It is widely used in aerial photography, environmental monitoring, power inspection and many other aspects. This makes the innovative research on the ejection device of light and small unmanned aerial vehicles more and more people's attention. [0003] At present, the catapults of most light and small unmanned aerial vehicles on the market are simple in structure, low in manufacturing cost, and use rough rubber bands for electric ejection. The acceleration during the sliding process will become smaller and smaller, resulting in longer acceleration time. As for oil-powered UA...
