DETAILED DESCRIPTION

[0021] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0022] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-Figure 6 As shown, the embodiment of the present invention provides a bionic penguin double-rotor cross-medium aircraft, comprising two fuselages 11, a tail 12 and a nose 13. The two fuselages 11 are interlocked with each other, and the nose 13 and the tail 12 are respectively installed at the front and rear ends of the two fuselages 11. The fuselages 11 and the side wings 15 are bionically designed according to the penguin shape. Since the fuselage 11 and the side wings 15 are bionically designed according to the penguin as a whole, the shape of the air-sea cross-medium aircraft is similar to that of a penguin. Once a covert action is required, it is only necessary to control the bionic penguin double-rotor cross-medium aircraft to dive underwater, thereby effectively solving the problem that the existing air-sea cross-medium aircraft cannot realize covert actions, and can significantly reduce the resistance during underwater navigation. A power output assembly 101 is arranged inside the fuselage 11, and the power output assembly 101 includes two side mounting plates 14, two trusses 18, a rotor 20, a universal joint 21, two ball head tie rods 22, two control steering gears 23, a drive motor 25, a rotary bearing 33 and two truss steering gears 32. Two guide channels 29 are symmetrically opened on the outer side wall of the fuselage 11, and the rotor 20 is located inside the guide channel 29; Two truss steering gears 32 are installed on both sides of the two side mounting plates 14. One end of the truss 18 is fixedly connected to the output shaft of the truss steering gear 32, and the other end of the truss 18 is rotatably connected to one side mounting plate 14 through a rotary bearing 33. The truss steering gear 32 drives the truss 18 to rotate, so as to change the direction of the rotor 20 and adjust the output direction of the power. By changing the direction of the rotor 20 and adjusting the output direction of the power, the bionic penguin dual-rotor cross-medium aircraft can have two navigation states: air and underwater. like Figure 1 As shown, the aircraft moves in the vertical direction; like Figure 6 As shown, the aircraft moves in the horizontal direction; When flying in the air, the position of the truss 18 is adjusted by the truss steering gear 32 so that the rotation axis of the rotor 20 is perpendicular to the direction of the fuselage 11. At this time, the thrust generated by the rotor 20 causes the fluid to be sucked in and out along the guide channel 29, and the aircraft cruises in the mode of a tandem twin-rotor helicopter; When sailing underwater, the position of the truss 18 is adjusted by the truss steering gear 32 so that the rotation axis of the rotor 20 is parallel to the direction of the fuselage 11. At this time, the aircraft cruises in the mode of an underwater vehicle; A steering gear fixing frame 24 is installed on the truss 18, a universal joint 21 is rotatably connected to the upper surface of the steering gear fixing frame 24 through a ball joint, a driving motor 25 is installed on the top of the universal joint 21, and a rotor 20 is installed on the output shaft of the driving motor 25. One end of two ball joint tie rods 22 is rotatably connected to two adjacent ball joints of the universal joint 21, and the other ends of the two ball joint tie rods 22 are fixedly connected to the output shafts of two control steering gears 23, and the control steering gears 23 are installed inside the steering gear fixing frame 24; Since the control servo 23 is linked to the universal joint 21 through the ball head pull rod 22, under the action of the two control servos 23, the two ball head pull rods 22 pull the universal joint 21 to change the orientation, which can further realize the omnidirectional movement of the rotor 20 and form a vector propulsion mechanism, thereby making the bionic penguin twin-rotor cross-medium aircraft more flexible and more sensitive in posture.

[0024] In one embodiment, a support frame 17 is installed on the opposite surfaces of the two side mounting plates 14. Two electronic compartments 19 are symmetrically installed on the support frame 17. The electronic compartment 19 is used to protect the electronic components to prevent water from damaging them. When repair and maintenance are required, the electronic compartment 19 can be removed and opened. In one embodiment, the electronic cabin 19 is provided with a navigation module for navigation, a communication module for communication, a power supply module for power supply, a storage module for data processing, a control module for control, and a switching module for connecting the modules. That is, the electronic cabin 19 makes the bionic penguin twin-rotor cross-medium aircraft more intelligent by setting up multiple modules.

[0025] In one embodiment, fence stripe-shaped guide slots 30 are provided on the rear part of the outer wall of the fuselage 11, the outer wall of the tail 12, and the outer wall of the nose 13; When the power output direction is parallel to the fuselage 11, the fence stripe-shaped guide slots 30 on the nose 13 introduce the suction flow for the propulsion mechanism, and the fence stripe-shaped guide slots 30 on the fuselage 11 and the fence stripe-shaped guide slots 30 on the tail 12 lead out the discharge flow for the propulsion mechanism; This can enable the aircraft to have higher propulsion efficiency and omnidirectional thrust output when sailing underwater and flying in the air.

[0026] In one embodiment, the power output assembly 101 further includes two side wings 15, two wing servos 16, a tail servo wing 26 and a tail servo 27; The two side wings 15 are respectively mounted on the output shafts of the two wing servos 16, the tail servo wing 26 is mounted on the output shaft of the tail servo 27, the tail servo wing 26 is rotatably connected to the inside of the tail 12, the tail servo 27 is mounted on the inner wall of the tail 12, the two wing servos 16 are symmetrically mounted on the far-away surfaces of the two side mounting plates 14, and the two side wings 15 are symmetrically located on both sides of the two fuselages 11; The side wings 15 are driven by the wing servos 16, and the tail servos 26 are driven by the tail servos 27. The direction can be changed by the side wings 15 and the tail servos 26, thereby assisting in completing the pitch attitude adjustment of the bionic penguin twin-rotor cross-medium aircraft.

[0027] In one embodiment, the power output assembly 101 is located inside the two fuselages 11, and the inside of the two fuselages 11 are fixedly connected with a guide plate 28. The guide plate 28 is arc-shaped and is located in front of the electronic compartment 19. When the exhaust flow of the front rotor 20 flows in the flow channel running through the fuselage 11, part of the fluid is diverted to the inside of the fuselage 11 through the arc-shaped guide plate 28, avoiding the electronic compartment 19, which can effectively reduce fluid resistance and obtain higher efficiency.

[0028] In one embodiment, a depth sensor 31 is installed at the bottom of the outer wall of the fuselage 11 below. The depth sensor 31 can be used to monitor the diving depth of the bionic penguin twin-rotor trans-medium aircraft at any time so as to perform diving control of the trans-medium aircraft in time.

[0029] In one embodiment, the two side mounting plates 14 are symmetrically fixedly connected with an upper connecting seat 34 and a lower connecting seat 35 on the far-away surfaces thereof, the outer side walls of the two fuselages 11 are provided with mounting holes 36, the upper connecting seat 34 and the lower connecting seat 35 are both located inside the mounting holes 36, the side mounting plates 14 are located inside the two fuselages 11, the upper fuselage 11 is fixedly connected to the side mounting plates 14 via the upper connecting seat 34, and the lower fuselage 11 is fixedly connected to the side mounting plates 14 via the lower connecting seat 35.

[0030] In order to solve the problems existing in the prior art, the embodiment of the present invention provides a bionic penguin dual-rotor cross-medium aircraft, and solves the problems through the above technology. When working: 1. The power output assembly 101 can tilt in different directions by controlling the cooperation of the servo 23 and the universal joint 21 to change the flight or navigation attitude of the cross-medium aircraft. At the same time, the side wing 15 can also change the pitch and roll of the cross-medium aircraft under the tilting of the wing servo 16 and the tail servo wing 26 can also change the pitch and roll of the cross-medium aircraft under the tilting of the tail servo 27, thereby controlling the flight or navigation attitude of the cross-medium aircraft. Second, when the bionic penguin dual-rotor cross-medium aircraft flies in an aerial mode, the rotor 20, with the cooperation of the truss servo 32 and the truss 18, can make the axis of the rotor 20 perpendicular to the fuselage 11, that is, the thrust is perpendicular to the fuselage 11, thereby realizing the vertical flight of the aircraft; 3. When the bionic penguin dual-rotor cross-medium aircraft is sailing in an underwater mode, the rotor 20 can make the axis of the rotor 20 parallel to the fuselage 11 under the cooperation of the truss servo 32 and the truss 18, that is, the thrust is parallel to the fuselage 11, and then the water flow is introduced through the fence stripe-shaped guide slits 30. Driven by the drive motor 25, the rotor 20 discharges water backwards to obtain a reverse force to sail forward; 4. The bionic penguin double-rotor cross-medium aircraft can enter and exit the water slowly with its head and tail kept horizontal. When entering the water, the bionic penguin double-rotor cross-medium aircraft keeps its head and tail in a horizontal direction, slowly lands on the water surface, reduces the rotation speed of the rotor 20, and enters the diving mode after the rotor 20 touches the water, and slowly sinks; similarly, when exiting the water, the bionic penguin double-rotor cross-medium aircraft still keeps its head and tail in a horizontal direction, slowly floats to the surface, and further increases the thrust to fly out of the water and into the air; 5. The bionic penguin twin-rotor cross-medium aircraft can quickly exit the water in a vertical posture. Before exiting the water, the bionic penguin twin-rotor cross-medium aircraft will quickly adjust its underwater posture under the joint action of the power output assembly 101, the rotor 20 and the tail rudder wing 26, so that the fuselage 11 is in a vertical state. At this time, the thrust direction of the upper and lower twin rotors 20 is consistent with the direction of the fuselage. Since the resistance along the direction of the fuselage 11 is small, the rapid exit from the water is completed perpendicular to the water surface and the aircraft quickly flies to the target after exiting the water. 6. The bionic penguin twin-rotor cross-medium aircraft can complete the entry and exit of water by tilting the fuselage 11. Before entering and exiting the water, the bionic penguin twin-rotor cross-medium aircraft will quickly adjust its posture under the joint action of the power output component 101, the rotor 20 and the tail rudder wing 26, forming a certain angle with the water surface to complete the entry and exit of the water.

[0031] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
