The working principle of the invention is as follows:
referring to the accompanying drawings of the specification 1-4, before the unmanned aerial vehicle needs to fly, the whole unmanned aerial vehicle needs to be assembled. Insert the storehouse 2 inside placing of organism 1 through dashpot 19 with horn 3 one end earlier, then peg graft the spout 7 inside with activity screw 6, run through the tip of horn 3 with activity screw 6, every activity screw 6 prescribes a limit to two horns 3 of organism 1 one side, thereby utilize two activity screws 6 to prescribe a limit to four horns 3, utilize the nut to prescribe a limit to 6 tip of activity screw to prescribe a limit to inside spout 7 with activity screw 6. After placing adjusting device inside placing storehouse 2, correspond the buckle with 8 both ends of bottom plate and two inside walls of organism 1 after, with two movable screw rods 6 inside spout 7 slides, and two movable screw rods 6 correspond the grafting with logical groove of first push pedal 9 and second push pedal 10 lateral surface respectively.
Can conveniently change whole unmanned aerial vehicle's length according to the distance between the 1 both sides rotor 4 of actual demand adjustment organism, and then increase whole unmanned aerial vehicle's overall stability, make things convenient for whole unmanned aerial vehicle adaptation in the high altitude environment of difference. When the distance between the two movable screws 6 in the machine body 1 needs to be adjusted, the rotating rod 12 is rotated. The screw effect of the rotating rod 12 and the movable plate 13 makes the movable plate 13 move up and down on the surface of the rotating rod 12. When the movable plate 13 moves downwards, the movable plate 13 drives the protruding rod to deflect downwards, at the moment, the top ends of the rotating plates 14 all rotate by taking the center line of the protruding rod as an axis, at the moment, the bottom end of the rotating plate 14 rotates inside the first push plate 9 and the second push plate 10, the included angle between the two rotating plates 14 on the surface of the protruding rod is gradually increased, so that the first push plate 9 and the second push plate 10 slide inside the limiting groove 11, the movable screw 6 is driven to move inside the sliding groove 7 stably, the two movable screws 6 are gradually kept away, and the machine arm 3 is enabled to gradually stretch out to be placed inside the bin 2. When the movable plate 13 moves upwards, the movable plate 13 drives the protruding rod to move upwards, at the moment, the top ends of the rotating plates 14 all rotate by taking the center line of the protruding rod as the axis, at the moment, the bottom end of the rotating plate 14 rotates inside the first push plate 9 and the second push plate 10, the included angle between the two rotating plates 14 on the surface of the protruding rod is gradually reduced, so that the first push plate 9 and the second push plate 10 slide inside the limiting groove 11, the movable screw 6 is driven to move inside the sliding groove 7 stably, at the moment, the two movable screws 6 are gradually close to each other, and then the machine arm 3 gradually enters the placing bin 2, according to actual needs, and therefore the adjustment of the exact position of the machine arm 3 by the adjusting device is completed.
After the position adjustment of horn 3 was accomplished, then adjusted buffer, rotated and changeed cover 18, utilized the spiral effect of the kelly of changeing cover 18 and link 15 one side for the side of changeing cover 18 corresponds the laminating with organism 1 lateral wall, simultaneously, changes cover 18 to another and adjusts, makes link 15 parallel with organism 1's lateral surface all the time. After the adjustment of link 15 was accomplished, with frame 20 and the 15 bottom threaded connection of link, thereby utilize buffer block 23 and the cooperation of second spring 22 to increase whole unmanned aerial vehicle's buffering effect.
When the unmanned aerial vehicle is used, the motor in the rotor 4 is controlled to operate through the built-in computer control system of the body 1, when the motor operates, the motor transmission shaft rotates circumferentially to drive the propeller to rotate circumferentially, so that aviation flight of the unmanned aerial vehicle aircraft is realized, wherein the built-in computer control system controls the motor in the rotor 4 to operate as a necessary technical structure in the aircraft, the structural principle of the structure is the prior known technology, and therefore the structure is not described in detail herein. When rotor 4 rotates, the screw rotation rate on rotor 4 is the same, when the lift that unmanned aerial vehicle produced was greater than unmanned aerial vehicle self gravity this moment, unmanned aerial vehicle is vertical to be risen, when needing to make unmanned aerial vehicle remove, control the motor speed on the horn 3 respectively, thereby adjust the lift of each horn 3, control unmanned aerial vehicle hover, retreat, rotatory or control flight, promptly keep away the barrier, avoid unmanned aerial vehicle collision barrier to lead to the plane crash out of control. When the lift force of the machine arm 3 is changed, the machine arm 3 rotates by taking the movable screw 6 as a circle center, the buffer groove 19 provides a space for the rotation of the machine arm 3, when the lift force of the machine arm 3 changes, the machine arm 3 drives the connecting frame 15 to move up and down through the sliding block 16, and at the moment, the connecting frame 15 slides on the outer side surface of the machine body 1 through the rotating sleeve 18.
When the horn 3 moves upwards, the connecting frame 15 rotates inside the sliding block 16, the sliding block 16 gradually moves towards the outer side of the horn 3, at the moment, the matching effect of the rotating sleeve 18 and the connecting frame 15 and the matching effect of the sliding block 16 and the first spring 17 enable the rotating sleeve 18 to be attached to the outer side face of the machine body 1, the connecting frame 15 is always parallel to the outer side face of the machine body 1, and the gravity center of the unmanned aerial vehicle gradually moves towards the positions of the other three horns 3; when the horn 3 moves down, link 15 rotates in 16 inside of slider, and slider 16 removes to the horn 3 outside gradually, changes the cooperation effect of cover 18 and link 15 this moment to and the cooperation effect of slider 16 and first spring 17, makes to change the laminating of cover 18 and 1 lateral surface of organism, makes unmanned aerial vehicle's focus move to the position of horn 3 gradually, conveniently controls unmanned aerial vehicle hover, retreat, rotatory or control the flight.
When the unmanned aerial vehicle lands on the ground, the buffer block 23 contacts with the ground firstly, at the moment, the gravity of the unmanned aerial vehicle impacts the ground, impact force recoils through the buffer block 23, at the moment, the buffer block 23 drives the movable nut 21 to move in the limiting groove 24, the impact force of the ground on the arm 3 of the unmanned aerial vehicle is reduced by utilizing the effect of the double second springs 22 at the top and the bottom of the movable nut 21, the impact force is transmitted to the connecting frame 15 through the frame 20, when the connecting frame 15 rotates in the sliding block 16, the connecting frame 15 has the tendency of driving the arm 3 to move upwards through the sliding block 16, so that the sliding block 16 is driven to gradually move towards the outer side of the arm 3, at the moment, the matching effect of the rotating sleeve 18 and the connecting frame 15 and the matching effect of the sliding block 16 and the first spring 17 further absorb the impact force on the ground, thereby generating a certain protection effect on the unmanned aerial vehicle, improving the anti-seismic performance of the unmanned aerial vehicle and reducing the abrasion of the unmanned aerial vehicle in the use process, the service life of the aircraft is prolonged, and the use of the aircraft is facilitated.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
