Abstract

The invention relates to the technical field of aircraft, in particular to an automatic tilting device of an electric helicopter. The automatic tilting device comprises a motor support (1), a tilting shaft (3), a tilting ball head (4), a fixed bracket (6) and a push-pull assembly. The upper part of the tilting shaft (3) is connected with the motor support (1); the middle part of the tilting shaft (3) is connected with the fixed bracket (6) through the tilting ball head (4); the tilting ball head (4) is connected to the outer surface of the tilting shaft (3) in a sleeving mode, and the lower part of the tilting shaft (3) is connected with the push-pull assembly. The device is small in occupied space, simple in structure, high in reliability, easy to disassemble and convenient to maintain; and a driving part of the whole device is installed in a helicopter body and is not interfered by the outside, only two telescopic push rod motors are needed for work, the manufacturing cost is low, the device is very matched with current mainstream pure electric large-scale, small-scale and miniature unmanned helicopters, and the device can be widely applied to the fields of surveying and mapping, transportation, routing inspection and the like, is simple in structure and is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to an electric helicopter automatic tilting device. Background technique [0002] With the advancement of technology, pure electric large, small and micro unmanned helicopters have developed rapidly and are widely used in surveying and mapping, transportation, inspection and other fields. During the working process of the helicopter aircraft, the helicopter automatic tilter responds to the control commands of the autopilot or the driver, adjusts the rotor tilt angle, changes the magnitude and direction of the lift force, and then controls the movement direction of the helicopter. The traditional tilting device needs three to four steering gears to control the tilting of the rotor disc. The steering gear drives the fixed ring of the automatic tilting device to tilt, and then drives the moving ring of the tilting device to tilt. The moving ring of the tilting device passes through th...
