Steering engine mounting fastener and mounting mode applied for small-sized unmanned aerial vehicle

Abstract

The present invention provides a steering gear installation fastener applied to a miniature unmanned aerial vehicle and an installation manner. A steering gear installation fastener is designed for installing a steering gear, which can install the steering gear to lie inside a stable face within limited space, is especially fit for the unmanned aerial vehicle which has high requirement towards a pneumatic appearance and realize the fast disassembly and assembly of the steering gear. When the steering gear is installed, firstly the steering gear is pressed and fastened to be blocked at the fastener, and then the steering gear is installed to lie inside a stable face by the connection of the fastener and a skin. A pressing connection fastening method is applied to the medium, small and miniature unmanned aerial vehicles to replace the prior bolt connection fastening, which can realize the convenient and fast disassembly and assembly of the steering gear, simplifies the installation and manufacture technology and reduces the weight and the cost.

Description

technical field [0001] The invention relates to the technical field of aviation machinery manufacturing, in particular to a steering gear connecting fastener and a steering gear installation method applied to a small unmanned aerial vehicle. Background technique [0002] The steering gear is a very commonly used device in the aviation field. It can convert electrical signals into mechanical motion signals, especially in the field of drones. Since there is no pilot to control, all the steering surface movements must be driven by the steering gear. For drones, the steering gear is like the muscles of the human body. Human movement depends on muscles, while the movement of the drone's steering surface depends on the steering gear. [0003] Steering gear is generally composed of three parts: motor, control chip and gear set reducer. In order to meet the requirements of aviation, it is usually made very small and light, but it needs to output a large force distance, and it also n...

AI Technical Summary

Problems solved by technology

Usually the shape of the steering gear is higher than the width, the position of the mounting hole makes the steering gear embedded in the stabilizer in the height direction, and the stabilizer is sometimes designed to be very thin in order to meet the aerodynamic requirements, even smaller than the height of the steering gear , so that the steering gear will protrude from the stabilizer, affecting the aerodynamic performance of the aircraft

In order to eliminate this disadvantage, it is necessary to install the steering gear "lying down", but this brings another problem: the original installation hole becomes parallel to the stabilizer surface in the stabilizer surface, in order to be able to install the fastening screws, It is necessary to open the process opening to ensure that there is enough space to install tools, which can damage the surface quality of the aircraft while ensuring easy installation
