It should be understood that the specific embodiments described here are only used to explain and illustrate the present utility model, and are not intended to limit the present utility model.

For a better explanation, the full name and direction of the utility model will be uniformly explained. The amphibious vehicle is referred to as equipment for short. for sideways.

The utility model only describes the innovative parts of the utility model in detail, and the engine and conventional transmission devices are not described.

The following is a detailed description of the device from the structure, function and operation during driving.

Referring to Fig. 1, the utility model is a kind of amphibious vehicle of water, land and air, which can run on land, on water, and in low altitude. The equipment includes an aircraft power system 100, an amphibious power system 200, a control system, an energy storage room, a driving and a passenger room.

In order to meet the flight function: referring to Fig. 6, the aircraft includes: aircraft power motor 110, propeller 120, propeller inner frame 130, propeller wing outer frame 140, steering gear 150, body 160, wherein the steering gear includes deceleration stepping motor, several transmission gear, casing;

Referring to Fig. 7, propeller 120 links to each other with aircraft power motor 110 by fixture, and power motor base is installed on propeller inner frame 130, and propeller inner frame 130 is installed on propeller wing outer frame 140, and steering wheel is installed on propeller wing outer frame 140. The steering gear 150 is connected to the inner frame 130 of the propeller. The positive and negative propellers need to be installed symmetrically. The propellers corresponding to the oblique angles of the quadrotor aircraft are the same, and the distance between the center of rotation of each propeller and the center of the aircraft is the same. Such a symmetrical distribution can make the counter torques when the propellers rotate cancel each other out.

Referring to Fig. 8, deceleration stepping motor one 152 is installed inside steering gear housing 151, and gear one 153 is installed on the output shaft of deceleration stepping motor one 152, referring to Fig. 4, the shaft on propeller inner frame 130 both sides is longer, passes The circular hole of propeller wing outer frame 140 stretches out, and bearing is installed at circular hole place, and the shaft of stretching part is equipped with transmission gear two 154, and meshes with gear one 153 on the reduction motor. The diverter housing 151 is mounted on the propeller wing outer frame. In this way, the rotation of the geared motor can drive the inner frame 130 of the descending propeller to rotate along the axial direction. The angle between the propeller and the power motor part can be adjusted by adjusting the deceleration stepping motor 152 through the control system, so as to satisfy the direction of adjusting the propeller, see FIG. 12 . When taking off and landing, the propeller provides vertical upward power for the aircraft. When flying at high speed, the propeller power direction is consistent with the forward direction, and the airflow maintains the height of the lift aircraft on the wings.

In order to meet the wing folding function: referring to Fig. 10 , the propeller wing outer frame 140 is connected to the body 160 by a shaft, and the propeller wing outer frame 140 can rotate sideways around the shaft. The inside of the frame is in contact with the body 160, preventing it from continuing to rotate. When turning upwards to a level, the outside of the wing axis of rotation is in contact with the upper side of the body 160, preventing it from continuing to turn upwards. Fig. 11 is a partial sectional view of the rotating shaft when the wing is fully folded. When the wing is turned to a horizontal state, the supporting side of the wing shown in the figure is in contact with the side of the main body 160, hindering further rotation, thereby maintaining the horizontal state .

In order to meet the folding function: the folding and stretching of the rotor part of the aircraft is entirely driven by propeller power, and this special structure is designed to ensure that the propeller wing outer frame 140 can be folded vertically downward and horizontally outward within the range of 90° Rotate, the force of the airflow on the propeller is always perpendicular to the plane of the propeller and outward, see Figure 9. In this way, under the action of lift force, gravity, and support force of the frame, as the speed increases, the folded part of the propeller rotates around the axis, and the outer frame 140 of the propeller wing automatically unfolds. , the wing extension process ends, and when the propeller is lower than this speed, the propeller wing outer frame 140 gradually turns downwards, and is blocked by the body 160 when turning vertically downward, and the wing folding process ends. The stretching and folding of the wings depends on a certain speed of the propeller, and this speed is much lower than the speed of flight, so the wings are always in the unfolded state during normal flight, which will not affect normal flight. In this way, the overall structure is simplified, the weight is reduced, the utility model has the advantages of energy saving and strong practicability.

The cross-section of the propeller wing outer frame 140 is shown in Figure 12. The middle part is protruding above and concave below, and is a streamlined structure, imitating the wings of a bird. According to Bernoulli's principle, when flying fast, the gas flow rate on the top is large. The flow rate of the gas below is small, and a pressure difference is formed on the upper and lower surfaces, and the gas generates upward pressure on the wings, providing upward lift for the aircraft.

In order to meet the function of traveling on water and land: referring to Fig. 13 and Fig. 16, the turbine blade group and the rotating shaft are installed inside the tire 212 and the outer hub 211, and can rotate without affecting each other. The turbine blade set and the outer shaft 230 are connected through the outer universal joint 221, the tire 212, the outer hub 211 and the inner shaft 230 are connected through the inner universal joint 222, and the inner universal joint 222 is installed inside the outer universal joint 221, and the two universal joints The center of the sphere of section 220 coincides. The outer shaft 230 is provided with a mechanical seal 251 at the inner and outer boundaries of the equipment, the inner shaft 230 is equipped with a gear three 265 in the equipment, and the outer shaft 230 is equipped with two gears in the equipment, namely gear four 261 and gear five 264, gear four 261 is connected to gear seven on the small generator 271 through gear six 262, and gear five 264 on the outer shaft 230 and gear three 265 on the inner shaft 230 can mesh with the internal gear 291 in the transmission shaft respectively. The internal gear 291 can slide at a certain position of the transmission shaft, as shown in FIG. 16 . The limit regulator 280 is installed and fixed with the small generator 271 and the transmission spur gear 281. The inner gear 291 is blocked in the middle of the limiter to control the movement of the inner gear 291, and there is a gap between the limit regulator 280 and the power output shaft 290. Direct contact, so that the rotation of the PTO shaft does not affect the limit adjuster 280 . The limit adjuster 280 is installed on the limit structure by two conical pressure bearings 282, wherein the limit adjuster 280 is engaged with the transmission spur gear 281, and the small generator 271 is connected with the outer shaft through gear four, gear five, and gear six. Gear eight is installed on the two 272 shafts of the deceleration stepping motor, and the eight gears are meshed with transmission spur teeth, so that the control deceleration stepping motor two 272 just can adjust the position of the limit adjuster 280 and the small generator.

Please refer to Figure 14, the inner shaft is connected to the inner shaft extension rod, and the inner shaft extension rod is connected to the inner shaft connecting rod through the inner cardan shaft. The outer shaft is connected with the outer shaft extension rod, and the outer shaft extension rod is connected with the outer shaft connecting rod through the outer cardan shaft.

When driving on land, the deceleration stepping motor 2 272 rotates, and the limit adjuster 280 is controlled to move, so that the internal gear 291 in the power output shaft 290 moves along the shaft, and disengages with the gear 5 264 on the outer shaft 230, and the internal gear 291 Move until meshing with gear three 265 on the inner shaft 230, at this moment, 265 on the small generator 271 meshes with gear six 262. Now the power output shaft 290 transmits the torque to the outer hub 211 and the tire 212, the outer hub 211 and the tire 212 rotate, and the equipment travels forward. In this way, controlling the steering of the power output shaft 290 can control the equipment to travel forward or backward. .

When driving on land or when the equipment is parked, see Fig. 19. At this time, since the small generator 271 is connected with the outer shaft 230 through gears, when there is side wind flowing through the wheels, the turbine blades will rotate, and the small generator will be driven. 271 turns and then stores the electrical energy in the battery. Since the direction of force between the turbine blades and the airflow is lateral, the equipment will not be affected when it travels forward and backward.

When turning on land, through the control of the steering wheel, the steering rod one 253 shown in FIG. The rotation of the outer universal joint 221 is indirectly controlled, thereby controlling the steering of the wheels.

When driving in water, the deceleration stepper motor 2 272 controls and adjusts the limiter to move, so that the internal gear 291 in the power output shaft 290 disengages from the gear 3 265 on the inner shaft 230, and moves to gear 5 on the outer shaft 230. 264 is engaged, and now the small generator 271 is disengaged from the gear five 264. In this way, the power output shaft 290 transmits the torque to the turbine blade set, the rotation of the power output shaft 290 drives the turbine blade set to rotate, and the device travels sideways.

When turning in water, the rotating speed of the turbine blade groups on both sides can be directly controlled to turn.

In order to meet the requirement that the equipment can float and be stable in water, the heavier mechanical energy storage chamber in the equipment is placed on the lower chassis to lower the center of gravity and improve stability.

The specific driving process will be described below.

The equipment is parked on land, as shown in Figure 19, the deceleration stepper motor 2 272 controls the inner gear 291 to mesh with the inner shaft 230 through the limit regulator 280, at this time, the small generator 271 and the outer shaft 230 are connected to the outer shaft 230 through gears, and the power The output shaft drives the outer wheel hub 211 and the tires to rotate, and the equipment moves forward. As long as the side wind flows through the wheels during driving or stops, the small generator 271 will be driven to rotate and generate electricity, which is stored in the battery.

When it is necessary to fly, as shown in Figure 2, the aircraft is parked on the ground and its wings are fully folded, ready to take off. The four aircraft power motors 110 are started, and the rotation speed increases gradually. When a certain rotation speed is reached, the wings begin to unfold gradually with the increase of the rotation speed. Wing extension ends when the wing turns to a horizontal state, as shown in Figure 1. The speed continues to increase. When it reaches a certain speed, the aircraft starts to leave the ground. Through the mediation of the control system, it takes off smoothly. Increase to provide the necessary lift. At this time, the aircraft flies upwards and forwards. When the propeller turns to the horizontal state, the lift is provided by the force of the gas on the wings. The power direction of the propeller is consistent with the forward direction, and it flies fast, as shown in Figure 3. When approaching the destination or needing to land, it is first necessary to slow down, the aircraft motor gradually decelerates, and at this time the steering system controls the axis of the propeller to rotate in the vertical direction. When turning to the vertical direction, the rotation speed of the four propellers can be adjusted so that The speed of the aircraft in the horizontal direction decelerates to zero. Same as Figure 1 at takeoff. Next, gradually reduce the speed of the propeller to make a smooth landing. When the speed drops to a certain speed, the wings begin to fold gradually, and when the speed drops to a lower speed, the folding process ends. The speed slowly drops to zero, and the landing ends.

The turbine blade group is a plurality of sets of turbine blades installed side by side, and the outside of the turbine blades is a blade reinforcement ring 213 .

When in water, the deceleration stepping motor 2 272 controls the internal gear 291 to disconnect from the gear 3 on the inner shaft 230 through the limiter, and meshes with the outer shaft 230. At this time, the small generator 271 and the gear 6 262 are disconnected. . The power output shaft 290 drives the turbine blade set to rotate, and controls the equipment to travel sideways.
