The invention discloses an anti-collision unmanned aerial vehicle with foldable wings. As a wing and an unmanned aerial vehicle body are arranged in movable connection with each other, a purpose of the foldable rings is realized through telescopic control and stretching of electric push rods; therefore, it is convenient for the unmanned aerial vehicle to smoothly enter a narrow space by using a remote controller to wirelessly control the folding of the wings during executing fire-fighting or express delivery tasks so that the wings cannot be damaged due to collision; as rotors are arranged between the two adjacent wings and the lengths of arms where the rotors are positioned are less than those of the wings, the rotors are uneasily damaged to due to collision with foreign objects during the flying of the unmanned aerial vehicle; as brackets are arranged in positions, close to the tail ends of the wings, on the back faces of the wings, the brackets can be used as a landing gear of the unmanned aerial vehicle; and as a solar cell panel is laid on the back of the unmanned aerial vehicle body, the solar cell panel can supply electric energy to the unmanned aerial vehicle so as to prolong the life of the battery. The anti-collision unmanned aerial vehicle with the foldable wings has the advantages of simple structure, foldability, collision resistance and beautiful appearance.
