Abstract
The utility model discloses a kind of many rotor unmanned aircrafts, comprise body, the surrounding of described body is provided with multiple hold-down arm symmetrically, described hold-down arm is provided with screw propeller, described screw propeller is connected with motor-driven, and drive propeller rotational by described motor, described motor is fixed on an end of described hold-down arm, the other end of described hold-down arm is removably connected on described body, and the rotation axis of each described screw propeller is all positioned on the same face of cylinder; The utility model has the advantage of: rotor connection structure is simple, installation or removal are convenient, and balance quality is high.
Description
Technical field
The utility model relates to a kind of unmanned vehicle, and specifically a kind of many rotor unmanned aircrafts, belong to unmanned vehicle field.
Background technology
Unmanned vehicle has that volume is little, lightweight, expense is low, flexible operation and the high feature of safety, can be widely used in taking photo by plane, monitor, search and rescue, the field such as resource exploration.Many rotor unmanned aircrafts are a kind of novel rotor class unmanned vehicles with vertical takeoff and landing, steadily hovering ability, compare traditional rotor helicopter, its physical construction simplifies, power control is simple, rotor size safety, manoevreability and autonomous controlling strong, become one of focus of novel Small and micro-satellite field of research.Multiple positive and reverse steering rotors that this aircraft generally adopts body center symmetrical, produce lift and moment of torsion by electrical energy drive driven by motor rotor, realize each to flight and spot hover of aircraft.Existing unmanned vehicle generally comprises multiple rotor, and each rotor is driven by a motor respectively, and rotor connection structure is complicated, and dismounting maintenance difficult, work efficiency is lower, and balance quality is poor.
Utility model content
In order to solve the problem, the utility model devises a kind of many rotor unmanned aircrafts, and rotor connection structure is simple, and installation or removal are convenient, and balance quality is high.
The technical solution of the utility model is:
A kind of many rotor unmanned aircrafts, comprise body, the surrounding of described body is provided with multiple hold-down arm symmetrically, described hold-down arm is provided with screw propeller, described screw propeller is connected with motor-driven, propeller rotational is driven by described motor, described motor is fixed on an end of described hold-down arm, the other end of described hold-down arm is removably connected on described body, the rotation axis of each described screw propeller is all positioned on the same face of cylinder, thus make many rotor wing unmanned aerial vehicles balance quality in flight course high, balance can be controlled more simply.
Further, the other end of described hold-down arm is threaded with described body, described hold-down arm is provided with connection negative thread, described body is provided with connection outside thread, described hold-down arm and body are equipped with fixed orifice, the fixed orifice of described hold-down arm is corresponding with the fixed orifice of described body, described fixed orifice is provided with gim peg, thus after hold-down arm is threaded with body, gim peg can be inserted in the fixed orifice of hold-down arm and body, can install or remove easily, and sound construction.
The utility model has the advantage of: rotor connection structure is simple, installation or removal are convenient, and balance quality is high.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
Embodiment 1
As shown in Figure 1, a kind of many rotor unmanned aircrafts, comprise body 1, the surrounding of described body 1 is provided with multiple hold-down arm 2 symmetrically, described hold-down arm 2 is provided with screw propeller 3, described screw propeller 3 is connected with motor-driven, propeller rotational is driven by described motor, described motor is fixed on an end of described hold-down arm 2, the other end of described hold-down arm 2 is removably connected on described body 1, the rotation axis of each described screw propeller 3 is all positioned on the same face of cylinder, thus make many rotor wing unmanned aerial vehicles balance quality in flight course high, balance can be controlled more simply.The other end of described hold-down arm 2 is threaded with described body 1, described hold-down arm 2 is provided with connection negative thread, described body 1 is provided with connection outside thread, described hold-down arm 2 and body 1 are equipped with fixed orifice, the fixed orifice of described hold-down arm is corresponding with the fixed orifice of described body, described fixed orifice is provided with gim peg 4, thus after hold-down arm is threaded with body, gim peg can be inserted in the fixed orifice of hold-down arm and body, can install or remove easily, and sound construction.
