SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an unmanned aerial vehicle for transportation to solve among the prior art fixture and can not adjust according to the shape of goods, lead to the not good problem of effect of centre gripping.

In order to achieve the above purpose, the technical scheme of the utility model is that: an unmanned aerial vehicle for transportation comprises a body, wherein two sides of the body are provided with swing arms, a first motor is fixed on the swing arms, and a rotor wing is fixed on an output shaft of the first motor; the machine body is provided with a cargo box, the inner side wall of the cargo box is provided with an air bag, two sides of the upper part of the inflated air bag can extend towards the center of the cargo box and can be contacted with the cargo box, an air pump and a second motor for driving the air pump to operate are fixed on the machine body, the air outlet end of the air pump is communicated with the air bag, and the air inlet end of the air pump is communicated with the outside; and a pressure sensor is arranged in the air bag and electrically connected with the second motor.

The working principle of the technical scheme is as follows: put into the goods incasement with the goods, open the second motor, the second motor drives the air pump work, aerifys in to the gasbag gradually, and the gasbag expands gradually to the shape of inflation is changed according to the outside shape of goods, then presss from both sides the goods tightly gradually, and when each part of gasbag all pressed from both sides the goods tightly, the gasbag can not continue the inflation again. The air pump continues to inflate inwards, the pressure in the air bag is increased, the pressure sensor senses the pressure at the moment, the second motor is closed, the air pump does not work any more, and the air pump stops pumping air into the air bag. Open first motor, first motor drives the rotor and rotates to drive unmanned aerial vehicle flight.

The beneficial effects of this technical scheme lie in: (1) this scheme utilization gasbag presss from both sides tightly the goods, can adapt to the shape of different goods, makes to press from both sides tight effect better. (2) Because the air bag belongs to soft substances, the air bag can clamp the goods and cannot cause hard damage to the goods. (3) Through setting up pressure sensor, can decide whether to close the second motor according to the tight condition of clamp, do not need the manual judgement, also more accurate than the manual judgement simultaneously.

Further, the both sides of organism are fixed with the third motor, and the output shaft and the spiral arm of third motor are connected, and the equal sliding connection in goods case upper portion left and right sides has the closing plate, the upper portion of gasbag is fixed in the one side that two closing plates are close to each other, all is fixed with the latch closure on two closing plates, is equipped with the screw rod between two latch closures, and the both ends of screw rod all are equipped with the nut, and the size of nut is greater than the size of latch closure. After the goods are placed in the goods box, the two sealing plates slide until the two sealing plates contact with each other, the screw penetrates through the two ring buckles, and the nut is rotated to be abutted against the ring buckles. The air bag is inflated, and the periphery and the upper part of the goods are clamped by the air bag. When the goods weight ratio of cargo tank is bigger, open the third motor, make the spiral arm rotate 180 degrees, drive unmanned aerial vehicle reversal, the cargo tank will be located unmanned aerial vehicle's below. Can guarantee the stability of unmanned aerial vehicle flight like this, avoid the goods focus too high, avoid unmanned aerial vehicle slope even uncontrollable.

Further, the machine body is detachably connected with the cargo box. When not needing the transportation goods, can dismantle the cargo tank, reduce unmanned aerial vehicle's bearing.

Further, still include the umbrella, the umbrella stick of umbrella can be dismantled with the bottom of cargo box and be connected. When the umbrella is in a thunderstorm weather, the umbrella handle of the umbrella is connected into the cargo box, so that the cargo is prevented from being damaged.
