The four rotor wing mechanisms are respectively arranged on the lateral surfaces of the frame (1).
Description
Technical field:
The present invention relates to the flight instruments technology, relate in particular to a kind of rotary and telescopic four rotor flight instruments technology.
Background technology:
Many rotors flight instruments is the motor-driven that is evenly distributed by 3-16, compare with the fixed-wing flight instruments with the butterfly of routine, the novel compactness of many rotors flight instruments topology layout, big, the mobility strong, safe and reliable of lift, can fly with various attitudes on fast and flexible ground, as hover, precedingly fly, side flies and inverted flight etc., and then dwindle swinging radius greatly, and therefore, can the work of efficient quick ground.
But even many rotors flight instruments but exists when not flying, the stretched condition when its rotor is still keeping flying, space hold are still very big, exist the inconvenient problem of storage carrying that is:.And three rotary wind type flight instrumentses are if one of them rotor damages, and it then can't continue flight, and five rotary wind type flight instrumentses (perhaps the sum of rotor surpasses five flight instruments) are because the increase of its rotor number must make its structure complicated.
Summary of the invention:
The present invention's purpose is:
Propose a kind of rotary and telescopic that can shrink freely four rotor flight instrumentses, make it simple in structure, the storage convenient in carrying.
In order to realize the present invention's purpose, intend by the following technical solutions:
The present invention comprises at least: frame, connecting key, by baffle plate, the jump ring device that spring is formed, by rotation connecting rod drive motor, rotary encoder, the rotation connecting rod, shrinking connecting-rod, the rotor mechanism that screw propeller drive motor and screw propeller are formed, it is characterized in that: screw propeller is fixed on the screw propeller drive motor, and be connected with an end of shrinking connecting-rod by the screw propeller drive motor, the side of the other end of this shrinking connecting-rod is provided with the jump ring device and is in the inside of rotation connecting rod, the side of this rotation connecting rod is provided with identical back limited bayonet and the prelocalization bayonet socket of catch size with the jump ring device, and this rotation connecting rod is installed on the frame, simultaneously, rotation connecting rod drive motor is fixed on the frame, the bottom of this rotation connecting rod drive motor is fixed with rotary encoder, and the output shaft of this rotation connecting rod drive motor is connected with the rotation connecting rod by connecting key.---the side of above-mentioned frame is respectively arranged with four rotor mechanisms.
Characteristics of the present invention are:
Even if one of them rotor among the present invention suffers to damage and can't work on, the present invention still can continue working flight by the lift of other three rotors.The rotation of the contraction of the present invention by four shrinking connecting-rods, the rotation connecting rod overall volume that is whole device under running condition not dwindle the condition created, be convenient to storage, carrying.
Description of drawings:
Fig. 1 has illustrated a kind of structure embodiment under the state of flight of the present invention.
Fig. 2 has illustrated contraction state of the present invention.
Fig. 3 has illustrated the present invention to rotate connecting rod and the rack-mounted state of rotation connecting rod drive motor.
Fig. 4 has illustrated shrinking connecting-rod of the present invention to be installed in the state on the rotation connecting rod.
1, frame; 2, rotation connecting rod drive motor; 21, the output shaft of rotation connecting rod drive motor; 3, rotary encoder; 4, rotation connecting rod; 41, back limited bayonet; 42, prelocalization bayonet socket; 5, jump ring device; 51, baffle plate; 52, spring; 6, shrinking connecting-rod; 7, screw propeller drive motor; 8, screw propeller; 9, connecting key.
The specific embodiment:
Jump ring device 5 of the present invention is arranged on the afterbody of shrinking connecting-rod 6, and it is made of catch 51 and the spring 52 that is arranged on catch 51 rear portions at least.Of the present invention is to be provided with four rotor mechanisms respectively four of frame 1 different sides, wherein the structure of rotor mechanism is achieved like this: screw propeller 8 is fixed on the output shaft of screw propeller drive motor 7, screw propeller drive motor 7 is installed in an end of shrinking connecting-rod 6, the other end of shrinking connecting-rod 6 is provided with jump ring device 5 and is in the inside of rotation connecting rod 4, the top of rotation connecting rod 4 is provided with identical back limited bayonet 41 and the prelocalization bayonet socket 42 of catch 51 sizes with jump ring device 5, and this rotation connecting rod 4 is installed on the frame 1, rotation connecting rod drive motor 2 is fixed on the frame 1, the bottom of this rotation connecting rod drive motor 2 is fixed with the rotary encoder 3 of the rotational angle of measuring rotation connecting rod drive motor 2 rotors, and the output shaft 21 of this rotation connecting rod drive motor 2 is connected with rotation connecting rod 4 by connecting key 9.
When the present invention need carry out aerial mission, the present invention is deformed into as schematically shown in Figure 1 state of flight from as schematically shown in Figure 2 contraction state: come driven in rotation connecting rod 4 by starting rotation connecting rod drive motor 2, the end that rotation connecting rod 4 is connected with shrinking connecting-rod 6 rotates to the direction away from frame 1, rotary encoder 3 records the rotational angle adjustment rotation connecting rod 4 of rotation connecting rod drive motor 2 rotors, make rotation connecting rod 4 turn to state illustrated in Figure 1, and, make the spring 52 at catch 51 rear portions compress by the catch 51 of pressing jump ring device 5 of the present invention, simultaneously, shrinking connecting-rod 6 is done under the effect of staff away from frame 1 motion, rotor mechanism elongation of the present invention is being positioned under the effect of spring 52 on the prelocalization bayonet socket 41 that rotates on the connecting rod 4 up to the catch 51 of jump ring device 5, relative displacement does not just take place for the present invention's shrinking connecting-rod 6 when state of flight with rotation connecting rod 4 in this, and then has created condition for the stabilized flight of flight instruments again.
When needs storages or carrying are of the present invention, the present invention is deformed into as schematically shown in Figure 2 contraction state from as schematically shown in Figure 1 state of flight: allow catch 51 separate with prelocalization bayonet socket 41 by make spring 52 shrink by lower stop piece 51, as schematically shown in Figure 4, shrinking connecting-rod 6 is done under the effect of staff near frame 1 motion, the catch 51 that rotor mechanism of the present invention shortens up to jump ring device 5 is being positioned under the effect of spring 52 on the back limited bayonet 42 that rotates on the connecting rod 4, and, come driven in rotation connecting rod 4 by starting rotation connecting rod drive motor 2, the end that rotation connecting rod 4 is connected with shrinking connecting-rod 6 rotates to the direction near frame 1, rotary encoder 3 records the rotational angle adjustment rotation connecting rod 4 of rotation connecting rod drive motor 2 rotors, make rotation connecting rod 4 turn to contraction state illustrated in Figure 2, for convenient storage or carrying the invention condition.
