Disclosure of Invention

The invention aims to provide unmanned aerial vehicles with protection functions, so as to solve the problem that equipment in a machine body is seriously damaged due to no buffer after the unmanned aerial vehicles fall to the ground.

In order to achieve the purpose, the basic scheme of the invention is that unmanned aerial vehicles with the protection function comprise a fuselage, wherein a plurality of rotor supports are fixedly arranged on the outer peripheral wall of the fuselage along the circumference, rotor blades are arranged on the rotor supports, a protection unit is arranged at the bottom of the fuselage and comprises a trigger box and a spherical protection plate, the peripheral wall and the bottom wall of the trigger box are fixedly connected with a elastic piece, the end of the elastic piece far away from the trigger box is fixedly connected with the spherical protection plate, the top end of the spherical protection plate surrounds the bottom end of the fuselage, a buffer ring is arranged on the periphery of the fuselage and surrounds the rotor supports, a end of each rotor support far away from the fuselage is fixedly connected with a second elastic piece, the end of the second elastic piece far away from the rotor supports is fixedly connected with the buffer ring, and the rotor blades are arranged in.

This basic scheme's theory of operation and beneficial effect lie in, unmanned aerial vehicle is falling to subaerial in-process, because the top of sphere guard plate surrounds the bottom of fuselage, and unmanned aerial vehicle's focus position is on the low side, unmanned aerial vehicle falls the in-process and can not overturn easily, consequently, can be sphere guard plate first and ground contact usually, then, elastic component will cushion the impact, thereby protect the fuselage, avoid the inside equipment of fuselage to receive violent impact and impaired seriously, realize the protection to unmanned aerial vehicle, thereby avoid great economic loss.

Moreover, when the unmanned aerial vehicle collides with the obstacle in the flying process, the unmanned aerial vehicle can be protected in the same way, when the buffer ring collides with the obstacle at first, the second elastic piece can buffer the impact force to avoid the impact force from damaging the unmanned aerial vehicle, in addition, the buffer ring can avoid the contact between the rotor blades and the obstacle, so as to avoid the damage of the rotor blades, and in the process of buffering the impact force by the second elastic piece, the unmanned aerial vehicle can change the flying route to bypass the obstacle, so as to avoid the whole unmanned aerial vehicle from colliding with the obstacle, so as to protect the unmanned aerial vehicle.

Optionally, every end fixedly connected with stop collar that the fuselage was kept away from to the rotor support is equipped with spacing pipe in the stop collar, and spacing pipe and stop collar radially have the clearance, and the end that the rotor support was kept away from to spacing pipe stretches out the stop collar and with buffer ring fixed connection, the second elastic component is located stop collar and stop collar.

Because there is the clearance between spacing pipe and the stop collar, consequently, radial movement and axial displacement can take place for spacing pipe in the stop collar, and spacing pipe radial movement's scope is limited moreover, then, when buffer ring and barrier collide with each other, unmanned aerial vehicle advances apart from limitedly, unmanned aerial vehicle advances fixed distance back and just no longer advances promptly, in order to guarantee that the rotor blade can not collide with the barrier all the time, provide sufficient time for unmanned aerial vehicle changes the flight route, thereby protect unmanned aerial vehicle.

Optionally, a partition board is horizontally connected in the trigger box and divides the trigger box into an upper chamber and a lower chamber, a through groove communicated with the upper chamber and the lower chamber is formed in the center of the partition board, a film is fixedly connected to the bottom wall of the upper chamber and covers and seals the through groove, channels are formed in the peripheral side wall of the lower chamber, rubber plugs are fixedly connected to the channels in a sealing mode, four fine wires are fixedly connected to the inner side wall of the spherical surface protection plate, the ends, far away from the spherical surface protection plate, of the fine wires penetrate through the corresponding rubber plugs and are fixedly connected with the film, the fine wires are in a stretched straight state, an annular air bag is fixedly connected to the peripheral wall of the machine body and is communicated with an air pipe, the end, far away from the annular air bag, of the air pipe is communicated with the upper chamber, a substance.

Therefore, in the scheme, when the spherical protection plate moves, the thin line is pulled to move, the thin film is torn by the thin line, the substance A in the upper chamber falls into the lower chamber through the through groove and meets the substance B, a large amount of gas is generated by immediate reaction, the gas is blown into the annular air bag through the air pipe, the annular air bag expands to form the buffer air cushion, and the impact force on the fuselage is buffered, so that the fuselage is protected, and the situation that equipment in the fuselage is protected from the large impact force is avoided.
