Description

Technical Field

[0001] The utility model relates to the technical field of UAV rotors, in particular to a transmission component of a UAV rotor. Background Technique

[0002] An unmanned aerial vehicle, abbreviated as "UAV" and with the English abbreviation "UAV", is an unpiloted aircraft that is controlled by a radio remote control device and a self - contained program control device, or is operated completely or intermittently autonomously by an on - vehicle computer.

[0003] The traditional transmission component of a UAV rotor directly drives the UAV rotor to rotate by an electric motor.

[0004] This type of transmission component of a UAV rotor has the following disadvantages: directly driving the UAV rotor by an electric motor requires multiple electric motors, which not only increases the weight but also increases the power consumption of the UAV. For this reason, we propose a transmission component of a UAV rotor. Content of the Utility Model

[0006] To achieve the above - mentioned purpose, the utility model provides the following technical solution: a transmission component of a UAV rotor, including a cabin, the outer surface of the cabin is provided with evenly distributed connecting columns, and the side of the connecting column far from the center of the cabin is provided with an installation shell, and also includes a transmission mechanism.

[0007] Transmission mechanism: including a coupling shaft, bevel gear II, a rotating rod, bevel gear I, a sleeve and bevel gear II. The middle of the connecting column is provided with a mounting plate, and the coupling shaft is rotatably connected in the rotating hole in the middle of the mounting plate. The side of the coupling shaft far from the center of the cabin is provided with bevel gear II. The middle of the installation shell is rotatably connected with a rotating rod, the middle of the outer surface of the rotating rod is rotatably connected with a sleeve, the lower ends of the sleeves are fixedly connected with bevel gear II, the lower ends of the rotating rods are provided with bevel gear I, bevel gear I and bevel gear II are meshed with bevel gear II, the upper ends of the rotating rods are provided with upper rotors, and the upper ends of the sleeves are provided with lower rotors. Driving multiple rotors by one electric motor reduces the weight of the fuselage and the power consumption of the UAV at the same time.

[0008] Further, a battery compartment is opened at the lower end of the cabin, and a storage battery is arranged in the battery compartment to supply power to the single - chip microcomputer.

[0009] Further, a single - chip microcomputer is arranged at the upper end of the cabin cover, and the input end of the single - chip microcomputer is electrically connected to the output end of the storage battery to control the electrical appliance.

[0010] Further, the transmission mechanism further includes a driving assembly, the driving assembly includes a slider and a bevel gear ring, a chute is provided on the bottom wall of the cabin, evenly distributed sliders are slidably connected in the chute, the upper ends of the sliders are fixedly connected to the lower end of the bevel gear ring, and a first bevel gear is arranged on one side of the connecting shaft close to the center of the cabin. The first bevel gears are all meshed with the bevel gear ring to drive the upper rotor and the lower rotor.

[0011] Further, the driving assembly further includes an electric motor and a third bevel gear. An electric motor is arranged in the middle of the bottom wall of the cabin. A third bevel gear is arranged at the rear end of the output shaft of the electric motor. The third bevel gear is meshed with the bevel gear ring. The input end of the electric motor is electrically connected to the output end of the single-chip microcomputer to drive the bevel gear ring.

[0012] Further, a wireless transmitter is arranged at the upper end of the cabin cover. The output end of the wireless transmitter is electrically connected to the input end of the single-chip microcomputer to remotely control the single-chip microcomputer.

[0013] Further, evenly distributed supporting feet are arranged at the bottom of the cabin to support the cabin.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: The transmission assembly of the rotor of this unmanned aerial vehicle has the following advantages:

[0015] Turn on the electric motor to drive the bevel gear ring to drive the second bevel gear to rotate. Since the second bevel gear is simultaneously meshed with the first bevel gear and the second bevel gear, when the second bevel gear drives the rotating rod to drive the upper rotor to rotate clockwise, it also drives the sleeve to rotate counterclockwise on the outer surface of the rotating rod, driving the upper rotor to rotate counterclockwise.

The transmission mechanism 2 further includes a driving assembly 21. The driving assembly 21 includes a slider 213 and a bevel gear ring 214. A chute is provided on the bottom wall of the cabin 1.

The electric motor 211 drives the bevel gear ring 214 to drive the second bevel gear 24 to rotate. Since the second bevel gear 24 is meshed with the first bevel gear 26 and the second bevel gear 28 at the same time, when the second bevel gear 24 drives the rotating rod 25 to drive the upper rotor 8 to rotate clockwise, it also drives the sleeve 27 to rotate counterclockwise on the outer surface of the rotating rod 25, driving the upper rotor 8 to rotate counterclockwise. In this way, the takeoff of the drone is realized.
