Problems solved by technology

[0002] When the unmanned helicopter is in flight, many of the rotor system, mechanical transmission system, flight control system, automatic navigation system, landing gear and communication equipment on the unmanned helicopter may be damaged by itself and interfered by other wireless signals, causing serious air accident
For example, unpredictable risks such as loss of engine power, failure of the transmission system, sudden change of load during flight, and complex flight environment, and the interruption of the communication link between the unmanned helicopter and the tower caused by the interference of surrounding signals during flight may also cause unmanned The trajectory of the helicopter deviated, causing serious crashes

Abstract

The invention relates to a safety emergency power device of an unmanned helicopter and belongs to the technical field of the flight safety of unmanned helicopters. The safety emergency power device comprises a gear box body; the gear box body is connected with two sets of power mechanisms; an engine of the main power mechanism is connected with a front belt wheel through a front belt; the front belt wheel is connected with a front gear through a spline; the front gear is supported on a sleeve through an overrunning clutch; the front gear is meshed with a main gear; a battery pack of the auxiliary power mechanism is fixed between the front belt and a rear belt; the battery pack is connected with a motor; the motor is connected with a rear belt wheel through the rear belt; the rear belt wheel is connected with a rear gear through a spline; and the rear gear is supported on the sleeve through the overrunning clutch; the front end of the rear gear is meshed with the main gear; and the rearend of the rear gear is connected with a tail transmission shaft. When the main power mechanism of the safety emergency power device of the invention breaks down or stops working, the auxiliary powermechanism can quickly respond to compensate main power.

Description

technical field [0001] The invention relates to an unmanned helicopter safety emergency power device, which belongs to the technical field of unmanned helicopter flight safety. Background technique [0002] When the unmanned helicopter is in flight, many of the rotor system, mechanical transmission system, flight control system, automatic navigation system, landing gear and communication equipment on the unmanned helicopter may be damaged by itself and interfered by other wireless signals, causing Serious aviation accident. For example, unpredictable risks such as loss of engine power, failure of the transmission system, sudden change of load during flight, and complex flight environment, and the interruption of the communication link between the unmanned helicopter and the tower caused by the interference of surrounding signals during flight may also cause unmanned The trajectory of the helicopter deviates, and serious cases lead to a crash.
