Description

Technical Field

[0001] The utility model relates to the technical field of autogyros, in particular to a regenerative braking type rotor structure. Background Art

[0002] An autogyro, abbreviated as a gyroplane, is a type of rotary-wing aircraft that uses a freely rotating rotor as the lifting surface and a propeller thrust as the forward driving force. The rotor of a gyroplane provides lift and attitude control moments such as pitch and roll. Therefore, different from a helicopter whose rotor is driven by an engine, once the engine stops in the air, the rotor of the gyroplane remains in a freely rotating state due to the oncoming flow blowing, so it can still land safely relying on the free rotation of the rotor. A gyroplane combines the characteristics of a helicopter and an airplane, has good low-altitude and low-speed performance and safety, and has lower manufacturing, use and maintenance costs and simpler operation than a helicopter.

[0003] When an autogyro takes off, it is necessary to pre-rotate the rotor. A rapid rotor pre-rotation can reduce the takeoff distance of the autogyro. When landing, appropriate braking and deceleration of the rotor can reduce the landing distance of the autogyro. Summary of the Utility Model

[0004] To solve the above problems, the purpose of the utility model is to provide a regenerative braking type rotor structure to achieve rapid pre-rotation and braking of the gyroplane.

[0005] In an embodiment of the utility model, the following scheme is adopted: A regenerative braking type rotor structure includes a rotor mast, a rotor seat and a rotor disc arranged on the gyroplane. The rotor seat is hinged to the rotor mast so that it can tilt forward and backward, and the rotor disc is rotatably arranged on the rotor seat. The structure further includes a mounting seat, a pre-rotation motor, a transmission mechanism, a clutch, a storage battery, a power controller and a pre-rotation shaft. The mounting seat is arranged at the rear side of the rotor seat. The pre-rotation motor is arranged outside the rear side of the mounting seat. The pre-rotation motor is connected to and rotates the transmission mechanism. A clutch is arranged at the upper part of the transmission mechanism. The pre-rotation shaft is sleeved inside the clutch. The top of the pre-rotation shaft meshes with the rotor disc. The storage battery is electrically connected to the power controller, and the power controller is electrically connected to the pre-rotation motor. The power controller controls the pre-rotation motor to charge / discharge the storage battery. When the gyroplane takes off, the pre-rotation motor rotates to drive the rotor disc through the transmission mechanism. When the gyroplane decelerates and lands, the rotor disc drives the pre-rotation motor to generate electricity.

[0006] Preferably, the mounting seat includes side plates, a rear plate and rib plates. Two side plates are locked on both sides of the rotor seat. The two side plates are respectively connected to both sides of the rear plate. The pre-rotation motor is installed outside the rear plate. The rib plates support between the two side plates and the rear plate. An opening for the pre-rotation shaft to pass through is formed in the rib plates. A wedge-shaped notch is formed at the bottom of the side plate facing the rotor mast.

[0007] Preferably, a bearing seat is further provided at the bottom of the mounting seat, and the transmission mechanism is sleeved inside the bearing seat.

[0008] Preferably, the transmission mechanism and the clutch are meshed and driven by a pair of bevel gears.

[0009] Preferably, the storage battery and the power controller are arranged on the side wall of the rotor mast, and a protective housing is further sleeved outside the storage battery and the power controller.

[0010] Preferably, an electric push rod is respectively arranged on both sides of the rotor mast, the tops of the two electric push rods are hinged to both sides of the rear part of the rotor seat, the electric push rods are electrically connected to the power controller, and a brake pad is further arranged on the front side of the top of the rotor mast; when the rotor disc brakes, the electric push rod pushes the rotor seat to incline forward, and the rotor disc on the rotor seat rubs against the brake pad.

[0011] Preferably, the top of the brake pad is made of high-temperature resistant rubber.

[0012] The utility model provides a regenerative braking type rotor structure. Compared with the prior art, the utility model has at least the following technical effects: by arranging a pre-rotation motor and realizing the pre-rotation and kinetic energy recovery of the motor through a storage battery and a power controller, the utility model can not only realize the rapid pre-rotation of the rotor of the autogyro, but also facilitate the deceleration of the rotor. When the rotor decelerates, the pre-rotation motor charges the storage battery. The advantages of such a design are as follows: the conversion of energy is fully utilized, and the volume of the carried battery is greatly reduced. The pre-rotation system is streamlined, the maintainability of the pre-rotation system is good, and the daily maintenance is simple. Description of the Drawings
