Abstract

The invention discloses a case opening and closing system of an unmanned helicopter. The unmanned helicopter comprises a case, a motor, a rotor wing and a tail pipe. One end of the motor and one end of the tail pipe are installed in the case. The case opening and closing system comprises a cabin opening formed in the upper portion of the case, an opening and closing cover installed in the cabin opening and a retraction device, the opening and closing cover is connected with the case through a hinge, and the retraction device is installed in the case and connected with the opening and closing cover to control the opening and closing cover to open or close the cabin opening. According to the case opening and closing system of the unmanned helicopter, compressed backspin airflow generated by high-speed rotation of the rotor wing is guided into the case through the cabin opening formed in the upper portion of the case, heat in the case is taken away by backspin airflow directly, heat dissipation efficiency is high, the motor located in the case can be rapidly cooled, the fault rate of the motor is reduced, the crash probability of the unmanned helicopter is reduced, and unnecessary economic loss is avoided.

Description

technical field [0001] The invention relates to the technical field of unmanned helicopters, in particular to a casing opening and closing system of an unmanned helicopter. Background technique [0002] Due to its strong weather adaptability, unmanned rotor helicopters are widely used in civilian and military fields, such as aerial photography, high-altitude wiring, line inspection and other operations. Under such circumstances, it needs to hover for a long time, and the unmanned helicopter cannot rely on high-speed movement for natural air cooling, and the internal temperature will rise, which will easily cause the engine to overheat and fail, and even cause the unmanned helicopter to crash, resulting in huge economic losses. [0003] The previous patent "Unmanned Helicopter with Engine Cooling Cover" application number: 201310635702.2 Although the above technical problems have been solved to a certain extent, there are still major defects. Only the cooling mesh of the cool...
