Description

Technical Field

[0001] The present application belongs to the technical field of unmanned aerial vehicles, and in particular, relates to a dual-rotor unmanned aerial vehicle with an independent structure. Background Art

[0002] A drone is an unmanned aircraft controlled by a radio remote control device and a self-contained program control device. Drones are actually a general term for unmanned aerial vehicles. From a technical point of view, they can be divided into several categories: unmanned helicopters, unmanned fixed-wing aircraft, unmanned multi-rotor aircraft, unmanned airships and unmanned paragliders. Single-rotor drones and multi-rotor drones are widely used in agricultural plant protection, power grid inspection, and even aerial photography.

[0003] The utility model with the existing authorization announcement number CN208412118U discloses a dual-rotor UAV with an independent structure, including a frame, a rotor assembly symmetrically arranged on the frame, and a power assembly for driving the two rotor assemblies respectively; the rotor assembly includes a propeller clamp, a propeller clamp support, and a cross plate, the propeller clamp and the propeller clamp support are assembled on the power shaft and are sleeved with a cross plate, the cross plate is symmetrically connected with a control rod, and the control rod is connected with a control servo.

[0004] The above technical scheme not only overcomes the problems of difficult single-rotor control and large take-off weight and large blade size, but also overcomes the problems of low endurance, low flight efficiency and small take-off weight of multi-rotor UAVs. It also has the advantages of flexible control, high flight efficiency and large load-bearing capacity of both single-rotor UAVs and multi-rotor UAVs. However, in the above technical scheme, the dual-rotor UAV uses two high-speed rotating rotors to drive the UAV to fly. Since no protective structure is set outside the two high-speed rotating rotors, the high-speed rotating rotors of the UAV may directly collide with other objects during flight, causing the rotor to deform or even be damaged. The high-speed rotating rotor may also cause damage to other objects, thereby greatly reducing the flight safety of the UAV.

[0005] To this end, we propose a dual-rotor UAV with an independent structure to solve the above problems. Summary of the invention

[0006] The purpose of the present application is to solve the problem in the prior art that the two high-speed rotating rotors of the drone cannot be protected, and to propose a dual-rotor drone with an independent structure.

[0009] Preferably, the ends of the two mounting rotors that are away from each other are fixedly connected to the UAV driving motor, and the inner wall of each lower protective cover is fixedly connected to the outer surface of the UAV driving motor.

[0010] Preferably, the output end of each of the drone driving motors is fixedly connected to a rotating propeller, and each of the rotating propellers is rotatably connected to the interior of the lower protective cover.

[0011] Preferably, both side surfaces of the drone body are fixedly connected with buffer sleeves, and the bottom surface of the drone body is fixedly connected with a lower mounting base plate.

[0012] Preferably, two groups of supporting legs are fixedly connected to the bottom surface of the lower mounting base plate, and the bottom end of each group of supporting legs is fixedly connected to the supporting base plate.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-4A dual-rotor UAV with an independent structure includes a UAV body 1, a front side of the UAV body 1 and a back side of the UAV body 1 are fixedly connected with mounting rotors 2, ends of the two mounting rotors 2 that are away from each other are fixedly connected with lower protective covers 5, ends of the two mounting rotors 2 that are away from each other are fixedly connected with UAV driving motors 3, the inner wall of each lower protective cover 5 is fixedly connected to the outer surface of the UAV driving motor 3, and by fixing the UAV driving motor 3 at the ends of the two mounting rotors 2 that are away from each other, the operation of the UAV driving motor 3 can be controlled by a remote control handle, thereby facilitating the flight control of the dual-rotor UAV.

[0024] The output end of each drone driving motor 3 is fixedly connected to a rotating propeller 4, and each rotating propeller 4 is rotatably connected to the inside of the lower protective cover 5. The drone driving motor 3 is used to drive the rotating propeller 4 to rotate at high speed, so that the two rotating propellers 4 can be used to drive the drone to take off and fly, thereby facilitating the control and use of the drone.

[0025] The outer surface of each lower protective cover 5 is fixedly connected to two lower connecting blocks 6, the interior of each lower protective cover 5 is clamped with an upper protective cover 7, the bottom surface of each upper protective cover 7 is fixedly connected to compression springs 10 arranged at equal distances, the bottom end of each group of compression springs 10 is fixedly connected to a mounting ring 11, and the bottom surface of each mounting ring 11 is in contact with the inner bottom wall of the lower protective cover 5, and the two side surfaces of the UAV body 1 are fixedly connected to buffer sleeves 16, and the bottom surface of the UAV body 1 is fixedly connected to a lower mounting base plate 15. Fixing the buffer sleeves 16 on both sides of the UAV body 1 can reduce the impact of the UAV with the ground due to the uncontrolled fall of the UAV, thereby reducing the damage to the UAV.

[0026] The outer surface of each upper protective cover 7 is fixedly connected to two upper connecting blocks 8, the bottom surface of each group of upper connecting blocks 8 is in contact with the upper surface of the lower connecting block 6, and the bottom surface of the lower mounting base plate 15 is fixedly connected to two groups of supporting legs 17, and the bottom end of each group of supporting legs 17 is fixedly connected to a supporting base plate 18. The support structure composed of the two groups of supporting legs 17 and the supporting base plate 18 can enable the drone to take off and land smoothly.

[0027] A rotating motor 19 is fixedly connected to the bottom surface of the lower mounting base plate 15, and a high-definition camera 20 is fixedly connected to the output end of the rotating motor 19. The rotating motor 19 and the high-definition camera 20 are controlled by a remote controller, and the rotating motor 19 can be used to drive the high-definition camera 20 to rotate, so that the high-definition camera 20 can be used to shoot the vicinity of the drone.

[0028] The interior of each set of upper connecting blocks 8 is threadedly connected with connecting bolts 9, and the bottom end of each set of connecting bolts 9 passes through the upper connecting block 8 and the lower connecting block 6 in sequence and extends to the bottom of the lower connecting block 6. The outer surface of each upper protective cover 7 is fixedly connected with two sets of mounting blocks 12, and the side surfaces of the two sets of mounting blocks 12 that are away from each other are fixedly connected with mounting springs 13. The two sets of mounting blocks 12 are used to install multiple mounting springs 13 on the outside of the upper protective cover 7, thereby improving the collision resistance of the drone.

[0029] The ends of the two groups of mounting springs 13 that are away from each other are fixedly connected with anti-collision rings 14, and the bottom surface of each group of anti-collision rings 14 is in contact with the upper surface of the lower protective cover 5. By utilizing the anti-collision rings 14 connected by the two groups of mounting springs 13, the upper protective cover 7 can be further protected by the anti-collision rings 14, thereby further improving the safety of the use of the drone.

[0030] The working principle of the present invention is: when in use, firstly, the drone body 1, the drone driving motor 3, the rotating motor 19 and the high-definition camera 20 are connected to the power supply provided in the drone. When the dual-rotor drone needs to be used for aerial photography, the drone is first placed on a horizontal ground manually, so that the support structure composed of the supporting legs 17 and the supporting bottom plate 18 can be used to stably set the drone at a required position. Then, the upper protective cover 7 is manually covered on the lower protective cover 5, and the compression spring 10 and the mounting ring 11 fixed under the upper protective cover 7 can be installed and clamped into the lower protective cover 5. By squeezing the compression spring 10, the upper protective cover 7 can be clamped into the lower protective cover 5 until the upper connecting block 8 fixed outside the upper protective cover 7 can contact the lower connecting block 6 fixed outside the lower protective cover 5, so that the upper protective cover 7 can be firmly fixed in the lower protective cover 5 by manually using the connecting bolts 9 to pass through the upper connecting block 8 and the lower connecting block 6, and then the protective structure composed of the lower protective cover 5 and the upper protective cover 7 can be used to protect the rotating propeller 4 rotating inside.

[0031] Then, by controlling the power supply of the drone driving motor 3 to drive the rotating propeller 4 to rotate at high speed, the drone will be able to fly. During the flight of the drone, the independent structure composed of the rotating motor 19 and the high-definition camera 20 can be used to drive the high-definition camera 20 to rotate through the rotating motor 19, so that the high-definition camera 20 can be used to shoot the environment near the drone. When the drone collides with other objects, the protective structure composed of the lower protective cover 5 and the upper protective cover 7 will be used to protect the high-speed rotating propeller 4, and the anti-collision ring 14 fixed to the outside of the upper protective cover 7 by the installation spring 13 can further reduce the impact force directly applied to the drone by the colliding object.
