Problems solved by technology

[0003] Most of the oil-operated piston engines of existing UAVs use the servo linkage to control the opening and closing of the engine throttle. The working conditions of the UAV engine are becoming more and more harsh. The connecting rod of the steering gear is often corroded by the liquid medicine or rainwater, and the movement of the corroded connecting rod is mostly jammed or stopped, which directly affects the work of the engine, so that the operation of the UAV There are hidden dangers

Abstract

The invention relates to the technical field of unmanned aerial vehicles, in particular to an electronic injection valve body assembly and an unmanned aerial vehicle. The electronic injection valve body assembly comprises an electronic injection valve body, a throttle valve shaft is rotationally arranged in the electronic injection valve body, and a throttle valve blocking piece used for adjusting the opening degree of an electronic injection valve is fixedly arranged on the throttle valve shaft; and the steering engine shell is connected with the electronic injection valve body in a sealed mode, a steering engine is fixedly arranged in the steering engine shell, and the steering engine is connected with the throttle valve shaft through a transmission structure. According to the arrangement mode, the steering engine is arranged in the steering engine shell, and the steering engine shell is hermetically connected with the electronic injection valve body, so that water and dust can be prevented, and the reliability of the engine is improved. Meanwhile, the steering engine directly drives the throttle valve shaft to rotate through the transmission structure, the response speed of the throttle valve can be increased, and the air inflow of the engine can be more accurately controlled.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an electronic fuel injection valve body assembly, an engine assembly and an unmanned aerial vehicle. Background technique [0002] With the rapid development of science and technology, in recent years, the application of UAVs to various industries has become more and more extensive. Gas pipeline inspection, highway accident management, forest fire prevention inspection, pollution environment survey, emergency rescue and rescue, rescue and disaster relief and other fields. [0003] Most of the oil-driven piston engines of existing UAVs use the steering gear connecting rod to control the opening and closing of the engine throttle. It is often corroded by liquid medicine or rain, and the movement of the corroded connecting rod is mostly stuck or stopped, which directly affects the work of the engine, thus causing hidden dangers in the operation of the drone.
