Embodiment

The present invention is further described with reference to the accompanying drawings and examples：

In the present embodiment, refering to Fig. 1, Fig. 2, Fig. 4 and Fig. 5, the unmanned plane fall protection system unmanned plane falling guard system System includes body 100, horn 200, motor 210, undercarriage and flies control module, and the winged control module is arranged in body 100, simultaneously Electrically connected with the motor 210, described one end of horn 200 sets the other end of motor 210 to connect the body 100, described The middle part of body 100, which is hung down, sets a hollow channel, and the centrifugal shaft 300 being slidably matched with it is provided with the hollow channel, described Undercarriage is made up of the foot stool 400 for being hinged on the centrifugal shaft lower end, and the foot stool 400 is in centered on the lower end of centrifugal shaft 300 Umbrella is distributed, and the infraoral of the hollow channel is provided with the limited mouth for limiting the umbrella distribution open angle of foot stool 400 140, the diameter after the foot stool 400 is gathered is less than or equal to the diameter of the hollow channel, and the upper oral part of the hollow channel sets Be equipped with regulation ring 110, the centrifugal shaft 300 coaxially passes through the regulation ring 110, be provided with the regulation ring control it is described from The motor 130 that mandrel 300 lifts, the week side of boss of the regulation ring 110 are equipped with the elasticity for connecting the upper surface of body 100 Connector 120, winged control module control motor 210 after monitoring that unmanned plane is out of control turn in the same direction.

The foot stool 400 uses torsion spring control 400 outside umbrella like expansion of foot stool after being hinged with the centrifugal shaft 300.

Gyroscope, GPS, compass, vision module, the ultrasonic wave that the winged control module includes monitoring unmanned plane position position Module, light stream locating module, motor torsion monitoring modular.

Refering to Fig. 7, rotation direction of the propeller as schemed left side during unmanned plane normal flight, multiaxis unmanned plane is all with adjacent Propeller reversely rotates and overcomes torsion of the propeller to unmanned plane body, prevents unmanned plane rotation, and turn by propeller Speed difference control unmanned plane rotates.

The winged general all internal or external above-mentioned module of control module, the winged control module can be perceived certainly by above-mentioned module Oneself flight position, direction, height, motor whether stall, when unmanned plane hits or be out of control, above-mentioned module will can instantaneously be sent out The raw abnormal state of flight very first time is transmitted to the winged control module, when abnormal state of flight is beyond the threshold for flying control module setting During value, the rotation direction of the motor 210 is consistent by the winged control module, can be to body when being rotated due to propeller 100th, horn 200 applies the torsion of opposite direction, and when all motors 210 all rotate in the same direction, the body 100 is by edge Opposite direction quickly rotates, refering to Fig. 7.

Refering to Fig. 1, Fig. 2 and Fig. 3, the centrifugal shaft 300 divides for upper semiaxis and lower semiaxis, the upper semiaxis and lower Semi-shaft rotary Turning to be movably connected, the regulation ring 110 is arranged on the upper semiaxis, and the foot stool 400 is articulated with the lower end of the lower semiaxis, point Flexible connection from after, the undercarriage and body 100 for alloing the unmanned plane of rotation landing possess different rotating speeds, make unmanned plane Make undercarriage static because of landing after landing, while body 100 keeps rotation, and it is inclined to prevent that undercarriage from because of rotation occurring position Move.

Refering to Fig. 6, the section of horn 200 is in lifting wing structure, makes the source of the constituting portion decilitre power of horn 200, enters One step reduces the speed that unmanned plane falls.

Refering to Fig. 1-3, the opening direction evagination of the non-articulated end of the foot stool 400 along foot stool is into boss.

The Flexible Connector 120 is elastic rubber band.

The method of operation of unmanned plane fall protection system in above-described embodiment：

Refer to Fig. 1 states under normal condition during the landing of unmanned plane, the motor 130 of the regulation ring 110 control it is described from Foot stool 400 in mandrel 300 stretches out, and the umbrella like expansion of foot stool 400 supports body 100, after taking off, the regulation ring 110 Motor 130 control the centrifugal shaft 300 to rise, the umbrella of foot stool 400 collapses into the hollow channel, and lands When, motor 130 controls the foot stool 400 on the centrifugal shaft 300 to stretch out again.

After unmanned plane collision is out of control, the rotation direction of the motor 210 is consistent by the winged control module, due to spiral shell When revolving oar rotation, the torsion of opposite direction can be applied to body 100, horn 200, when all motors 210 all revolve to same direction When turning, the body 100 will quickly rotate in reverse direction, refering to the change of Fig. 7 left figures to right figure.The body 100 quickly revolves Turn, unmanned plane will be made equally to obtain gyroscopic inertia similar to gyro, unmanned plane will be perpendicular to horizontal plane rotation under gravity, and residual Remaining propeller lift slowly falls the unmanned plane for making rotation straight, and when falling, foot stool 400 is protected on the centrifugal shaft 300 Contraction is held, because the impulsive force that unmanned plane falls makes foot stool 400 travel further into the hollow channel, the potential energy quilt of decline after landing The Flexible Connector 120 absorbs buffering, at the same body 100 do not stop the rotation also continue it is stable perpendicular to ground, unmanned plane Safety and stability is dropped into ground.

Described is only presently preferred embodiments of the present invention, is not intended to limit the invention, all in the spirit and principles in the present invention Within, any modification, equivalent substitution and improvements made etc., it should be included in protection scope of the present invention.
