In particular, the steering means is a joystick that can be manually operated in the front, rear, left and right directions to rotate forward, backward, turning, brake, in place.

The duct propeller is a propeller rotatably installed in the duct body with a vertical line in the vertical direction in the rotation axis; A propeller motor connected to the rotating shaft of the propeller to drive the propeller; And a duct motor installed laterally on the outer circumferential surface of the duct body to adjust the propeller angle in the up and down direction, including being able to rotate forward, backward, turning, brake, and in place.

The duct type propeller includes a gyro sensor or a distance measuring sensor for detecting the height between the ground or the water surface from the duct body; And a controller configured to adjust a balance by receiving a signal from the gyro sensor or a distance measuring sensor and controlling the speed of the propeller through a motor.

Referring to the advantages of the hybrid-driven amphibious transport apparatus according to the present invention.

The hybrid drive device of the present invention is divided into a driving mode such as floating / forward / reverse / left / right / stop rotations according to the angle and RPM of the left ducted propeller 20a and the right ducted propeller 20b.

Floating mode

The floating mode is a mode for starting the first driving, and is a mode in which both the left ducted propeller 20a and the right ducted propeller 20b are kept horizontal (0 °) while braking is performed.

To this end, the propeller motor 28 of the left ducted propeller 20a and the propeller motor 28 of the right ducted propeller 20b are driven at the same low RPM while the braking means 16 is braked. The propeller 24 of the ducted propeller 20a and the propeller 24 of the right ducted propeller 20b are rotated so that both the left ducted propeller 20a and the right ducted propeller 20b are horizontal (0 °).

The duct bodies 22 of the ducted propellers 20b are all angularly rotated (about 20 °) toward the front side.

At this time, by driving the propeller motor 28 of the left ducted propeller 20a and the propeller motor 28 of the right ducted propeller 20b at the same high RPM, the propeller 24 of the left ducted propeller 20a and As the propeller 24 of the right ducted propeller 20b rotates, air escapes from the front of the duct 22 to the rear, and the driving force is generated, and the wheel 14 moves forward with the forward cloud.

Reverse mode

The reverse mode is a mode for reversing driving, in which both the left duct propeller 20a and the right duct propeller 20b are rotated angularly (about -20 °) toward the rear side when the braking is released.

To this end, by simultaneously driving the duct motor 26 of the left duct propeller 20a and the duct motor 26 of the right duct propeller 20b, the duct body 22 and the right side of the left duct propeller 20a. Both the duct bodies 22 of the duct-type propellers 20b are in the same angular rotation (about -20 °) toward the rear side.

At this time, by driving the propeller motor 28 of the left ducted propeller 20a and the propeller motor 28 of the right ducted propeller 20b at the same high RPM, the propeller 24 of the left ducted propeller 20a and As the air escapes from the rear of the duct body 22 to the front in accordance with the rotation of the propeller 24 of the right ducted propeller 20b, the driving force is generated, and the wheel 14 travels backward with the backward cloud.

Left turn mode

The left turn mode is a mode for driving left turn when moving forward. The left duct propeller 20a is horizontally maintained at 0 ° while the braking is released, and the right duct propeller 20b is rotated forwardly (about 20 °). To be in

Therefore, since the propulsion force is zero in the left duct propeller 20a, only the propeller 24 of the right duct propeller 20b is rotated so that the air is released from the front of the duct body 22 to the back so that the propulsion force is generated. In addition, the wheel 14 moves in a left-turn direction at the same time as a forward rolling cloud movement.

Right turn mode

The right turn mode is a mode for driving right turn when moving forward. When the braking is released, the right duct propeller 20b is horizontally maintained at 0 °, and the left duct propeller 20a is angularly turned forward (about 20 °). To be in

Therefore, the propulsion force is zero in the right duct propeller 20b, and only the propeller 24 of the left duct propeller 20a rotates so that the air is released from the front of the duct 22 to the back, so the propulsion force is generated. In addition, the wheel 14 moves in the right direction by rolling in the right direction at the same time as the forward rolling.

Stop Rotation Mode Rotation mode )

The stop rotation mode is a mode in which the left turn or the right turn is performed in the braking state of the braking means 16.

In the braking state, the left duct propeller 20a is horizontally maintained at 0 °, and the right duct propeller 20b is angularly rotated toward the front (about 20 °). A left turn drive is made.

On the other hand, in the braking state, the right duct propeller 20b is horizontally maintained at 0 ° and the left duct propeller 20a is angularly rotated (about 20 °) toward the front to be stopped by the thrust of the propeller. A right turn at

Here, with reference to FIG. 7 attached to the control process to prevent the left duct propeller 20a and the right duct propeller 20b from touching the ground during driving or braking to maintain the overall balance of the hybrid drive device of the present invention. Is as follows.

7 is an operational state diagram of the propeller for maintaining the balance of the apparatus in FIG.

First, the gyro sensor or distance measuring sensor mounted on the bottom of the duct body 22 of the left duct propeller 20a and the right duct propeller 20b detects the distance to the ground and transmits the detection signal to the microcontroller. To pass.

The transmitted detection signal, that is, the height (posture) value is calculated by the microcontroller and input to the propeller motor 28 as a PWM signal to adjust the output.

In more detail, the upper controller of the microcontroller receives feedback of the height between the duct body 22 and the ground through the closed loop control to automatically control the output of the propeller motor 28, that is, the propeller RPM. For example, as shown in the accompanying FIG. 7, when the distance is about 250 mm ± 100 mm from the ground, the output of the propeller motor 28 is adjusted to control the attitude of the fuselage frame 10 including the duct body 22 (balance). Maintenance) takes place.

In this way, by combining the at least one wheel 14 and the duct propeller 20 in combination, it is possible to provide a simple and convenient new concept of driving means capable of straight running and turning driving.
