Description
Technical Field
The utility model relates to a folding rotor craft field, in particular to rotor support arm folding mechanism.
Background
Compared with helicopters, fixed wings and other aircrafts, the multi-rotor aircraft is more stable in flying, can be quickly switched among various flying states such as hovering, side flying, back flying and the like, has good take-off and landing and maneuvering performances, is suitable for fixed-point reconnaissance, aerial photography, surveying and mapping and other tasks, and has wide military and civil applications.
The rotor support arms and landing gear of the conventional multi-rotor aircraft usually adopt a fixed structural form, so that the aircraft has a large volume and brings inconvenience to carrying and transportation.
Disclosure of Invention
The utility model aims at overcoming above-mentioned problem, provide a rotor support arm folding mechanism.
In order to achieve the purpose, the utility model discloses a method is: a rotor wing supporting arm folding mechanism comprises a machine body connecting piece, a spiral spring, a supporting arm connecting piece, a rotor wing supporting arm, a machine body connecting piece clamping pin and a supporting arm connecting piece clamping pin. Wherein, the fuselage connecting piece is articulated with the support arm connecting piece. The machine body connecting piece is fixedly connected with the machine body connecting piece bayonet lock. The support arm connecting piece is fixedly connected with the support arm connecting piece bayonet lock. Two ends of the spiral spring are sleeved on the machine body connecting piece bayonet lock and the supporting arm connecting piece bayonet lock. The support arm connecting piece is fixedly connected with the rotor wing support arm.
Preferably, one end of the support arm connecting piece is L-shaped, and the inflection point of the support arm connecting piece is hinged with the machine body connecting piece; the other end is cylindrical and is fixedly connected with the rotor wing supporting arm. The whole supporting arm connecting piece can rotate around the hinged part, and the maximum rotating angle is 90 degrees.
Has the advantages that:
the utility model discloses technical scheme provides a rotor support arm folding mechanism is simple reliable, easily manufacturing, can conveniently realize the quick folding and the operation of opening of rotor support arm, and the rotor support arm after folding is difficult to rock, keeps the stability of rotor support arm after folding, can make full use of effective space around the fuselage for many rotor crafts after folding have less volume, portable and transportation.
