Protective case gos deep in the rotor of unmanned plane for preventing rod-like articles, produces obstruct the rotation of rotor; Protection ring is for avoiding unmanned plane to the shock of object in environment.
Preferably, described protective case and described protection ring are circular configuration, and the center of circle of described protective case overlaps with the center of circle of corresponding described rotor respectively, the center of circle of described protection ring and the center superposition of described unmanned plane.
Particularly, described sidewall is metal net shaped cylinder, the mesh of described sidewall is rectangular opening, described netted end plate comprises multiple endless metal silk and multiple straight wire, the center of circle of multiple described endless metal silk all overlaps with the center of circle of described sidewall and its diameter increases from the inside to the outside successively, and described straight wire arranges along the radial direction of described netted end plate and is fixedly connected with multiple described endless metal silk.
The air-flow that netted protective case can reduce rotor produces impacts, and makes unmanned plane can carry out various flare maneuver normally.
Preferably, the number of described endless metal silk is 4, and the ratio of the diameter of its diameter and described sidewall is followed successively by 1/4,2/4,3/4 and 1, the number of described straight wire is 12, and its length is 3/4 of the radius of described sidewall, 12 described straight wire are uniformly distributed along the center of circle of described netted end plate, and its two ends are fixedly connected with outermost described endless metal silk with the described endless metal silk of inner side respectively.
The air-flow that rotor produces strengthens from the inside to the outside successively, and the mesh of the netted end plate of protective case increases from the inside to the outside successively, decreases the interference to air-flow.
Preferably, the composition material of described protection ring is high-elasticity epoxy resin.
Elastomeric protection ring can carry out actv. buffering to impact, avoids excessive acceleration/accel to cause damage to each machinery of unmanned plane inside or electronic component.
The beneficial effects of the utility model are:
Four rotor wing unmanned aerial vehicles that the utility model has anti-collision protection device have all carried out actv. protection by protective case to the rotor of unmanned plane; avoid exterior object to enter rotor and impact its rotation; simultaneously the entirety of protection ring to unmanned plane is protected, the impact that acceleration/accel when alleviating shock by the buffering of protection ring causes unmanned plane.
