Title:

ROTORCRAFT, MOTOR HEAT DISSIPATION STRUCTURE, CONNECTING STRUCTURE FOR CRAFT ARM AND FUSELAGE, AND LANDING GEAR ASSEMBLY/DISASSEMBLY STRUCTURE

Document Type and Number:

WIPO Patent Application WO/2016/066009

Kind Code:

A1

Abstract:

A rotorcraft (1000). The rotorcraft (1000) comprises: a fuselage (100); a craft arm (200), where one extremity (201) of the craft arm (200) is connected onto the fuselage (100); rotor blades (300), where the rotor blades (300) are connected to a second extremity (202) of the craft arm (200), and the rotor blades (300) are driven into rotation by a motor (600); a motor heat dissipation structure (400) comprising: a housing (410), where the housing (410) is a hollow structure having a top opening and a bottom air inlet (411), a body of the motor (600) is provided within the housing (410), and an airflow channel (412) is formed between the periphery of the body of the motor (600) and the inner wall of the housing (410); a lid (430), where the lid (430) is synchronously connected onto a spindle of the motor (600), the lower surface of the lid (430) is provided with multiple airflow lifting pieces (431); and, a mounting base (450), where the mounting base (450) is fixed on the upper surface of the lid (430) and is used for connecting to the rotor blades (300). In addition, also disclosed are the motor heat dissipation structure, a connecting structure for the craft arm and the fuselage, and a landing gear assembly/disassembly structure. The operating ambient temperature of the motor of the rotorcraft is effectively reduced. The craft arm and the fuselage can be quickly assembled and disassembled. An assembly process of the rotorcraft is simplified.
