A notch 103 is formed in a position, on the first fixing plate 101, where the horn 20 needs to be installed, the width of the notch 103 satisfies that the end part of the horn 20 can be accommodated into the notch, and the folded and contracted horn is accommodated and limited through the notch 103.

And the folding device is arranged between the first fixing plate and the second fixing plate and is positioned at the notch 103. The folding device comprises a supporting frame 30, the supporting frame 30 comprises two parallel supporting members 300, the two supporting members are installed between a first fixing plate and a second fixing plate at two side positions of the notch 103, and the supporting members 300 are fixedly connected with the first fixing plate and the second fixing plate. A limiting mechanism is arranged between the two supporting pieces, the limiting mechanism is a buckle 40, the lower end of the buckle 40 is rotatably installed between the two supporting pieces 300 through a rotating shaft, the upper end of the buckle 40 is connected to the supporting pieces through a pressure spring 401, the pressure spring 401 is located on the inner side of the buckle, and a handle 404 is arranged on the outer side face of the upper end of the buckle. The outer side of the buckle under the handle 404 is provided with an arc-shaped surface 403. At the arc-shaped surface 403, a limiting groove 402 is arranged on the outer side surface of the buckle between the pressure spring 401 and the buckle rotating shaft.

The two supporting pieces positioned at the outer sides of the buckles are respectively provided with a rotating shaft 301 and a pin shaft 302. The pin 302 is located above the rotating shaft 301.

The connecting end 201 of the arm 20 is rotatably mounted between the two supporting members 300 through the rotating shaft 301, and the connecting end of the arm is located above the notch 103 and outside the buckle 40. A hollow part is arranged between the connecting end of the machine arm and the free end of the machine arm and close to one side of the connecting end of the machine arm. One end of the tension spring 202 is rotatably inserted into the pin shaft 302, and the other end is rotatably disposed on the hollow portion of the arm through the pin shaft 203. When the horn is in the horizontally extended state, the tension spring 202 is in the obliquely tensioned state.

The connecting end 201 of the horn 20 is provided with a limiting bump 204, and when the horn is in a horizontal extension state, the limiting bump 204 is clamped on a limiting groove 402 on the buckle 40 to limit the horizontal extension state of the horn. The connecting end surface at one side of the limiting bump 204 of the horn connecting end 201 is an arc surface 205, when the horn rotates, the arc surface 205 of the horn connecting end can rotate along the arc surface 403 of the buckle, and when the horn is in a horizontal extension state, the arc surface 205 of the horn connecting end is partially attached to the arc surface 403 of the buckle; when the horn is the folding shrink state, when the horn is the approximate vertical relation relative first fixed plate and second fixed plate promptly, the arcwall face 205 laminating of horn link 201 department supports and leans on the arcwall face 403 on the buckle lateral surface, and spacing lug 204 one side supports and leans on the buckle lateral surface of the arcwall face 403 top of buckle 40. The outer side surface of the buckle limits the folding and shrinking state of the machine arm. When the boom end portion is moved from the horizontally extended state to the folded and contracted state, the tension spring 202 is also changed from the obliquely tensioned state to the vertical natural state.

The unmanned aerial vehicle frame is folding: when the horn extends horizontally, the limit bump 204 of the horn connecting end is clamped in the limit groove 402 of the buckle 40, the tension spring 202 tensions the horn obliquely, and the pressure spring 401 provides an outward supporting force for the upper end of the buckle, so that the limit bump of the horn is tightly abutted with the limit groove of the buckle to provide limit for the horizontal state of the horn; when the horn is folding, press the buckle handle to the inboard, compress the pressure spring, make the buckle rotate to the inboard, make the spacing lug 204 of horn link break away from the spacing groove 402 of buckle 40, the horn rotates downwards under the action of gravity, loosen the buckle, the arcwall face of horn then rotates along arcwall face 403 on the buckle lateral surface, the buckle gives horn link outward turning pressure through pressure spring elasticity simultaneously, impel its quick folding, fold the back that targets in place, the arcwall face 403 of buckle lateral surface supports with the laminating of arcwall face 205 on the horn and lean on, one side that spacing lug 204 and arcwall face 205 are connected supports and leans on the buckle lateral surface above buckle arcwall face 403. The two ends of the tension spring 202 rotate to make the tension spring turn to a vertical natural state from the oblique tension device. After folding, accomodate unmanned aerial vehicle into storage cylinder and preserve.

When the horn needs to be opened, external force is applied to the horn, the horn rotates upwards under the action of the external force, the limiting lug at the horn connecting end presses the buckle to rotate inwards until the limiting lug at the horn connecting end enters the limiting groove, the horn stops rotating upwards, at the moment, the buckle rotates outwards under the action of the elastic force of the pressure spring to abut against the horn connecting end, so that the limiting lug and the limiting groove of the horn are locked, and horizontal limiting is realized; at the moment, the tension spring is converted into an oblique tensioning state from a vertical natural state, so that a supporting force is provided for the machine arm.

The external force is manually applied or the lifting force when the unmanned aerial vehicle throws. When in air throwing, the machine arm is slightly opened outwards, the propeller is opened, the machine arm is driven by the lift force to rotate and press into the buckle, and the air throwing can be machine throwing or hand throwing.

When the unmanned aerial vehicle horn is opened, can also realize through gravity. Take out unmanned aerial vehicle from the storage cylinder, reverse placing makes the unmanned aerial vehicle horn up, and the mounting bracket is down, and the horn is overcome the spacing rotation of buckle under the action of gravity, and spacing lug gets into automatic locking in the spacing groove of buckle, makes unmanned aerial vehicle be in but flight state fast.

Above-mentioned unmanned aerial vehicle frame, when using, at the other end of the relative link of horn, installation screw and driving motor on the free end of horn promptly, install various loads and power on the mount frame. Put under the power, make unmanned aerial vehicle focus lean on down, help unmanned aerial vehicle gesture level and upwards when unmanned aerial vehicle jettisonings.

Compared with other unmanned aerial vehicle models, the unmanned aerial vehicle manufactured by the unmanned aerial vehicle frame has the advantages that the separate taking-off and landing are required to be carried out in a wide and flat area, and the taking-off and landing of the unmanned aerial vehicle manufactured by the unmanned aerial vehicle frame are not limited by the terrain.
