Compared with the prior art, the invention has the beneficial effects that: the invention realizes the function that the electric automobile can be charged without stopping through the guide rail vehicle which runs on the power transmission guide rail and keeps the same running speed as the electric automobile and the aircraft which is connected with the guide rail vehicle by a lead wire, and realizes the transmission of the electric energy on the power transmission guide rail to the electric automobile through the aircraft and the guide rail vehicle, so that the electric automobile can be separated from the aircraft at any time under the full charge or other conditions, and the limitation on the free running of the electric automobile can not be caused. Compared with the existing electric bus with the pantograph arranged on the roof, the invention only needs to arrange the charging receiving module (such as a common contact type electric connection electrode or a wireless charging receiving module in the prior art) on the top of the electric automobile, so that the appearance of the electric automobile is not greatly influenced, and the improvement on the existing electric automobile is facilitated.
Because the number and the driving direction of the electric vehicles which need to be charged on each section of road are random, at least two groups of reversing guide rails need to be connected between two power transmission guide rails on two sides of the road, so that the guide rail vehicle can move from the power transmission guide rail on one side of the road to the power transmission guide rail on the other side of the road.
Furthermore, since there are non-linear rails (generally designed as circular arc in fig. 1) at the connection between the reversing guide rail and the power transmission guide rail and at the corners of the power transmission guide rail on the road, the second motor on one side of the guideway car is designed to be able to move in the left-right direction of the guideway car, so that the driving wheels on both sides can keep against the rails on both sides when the guideway car drives into the circular arc-shaped rails.
When the aircraft works, the first electromagnet is electrified to generate a magnetic field opposite to the permanent magnet, so that the aircraft is separated from the second cover plate.
When electric automobile needs to charge, the wire reel is rotated to emit the wire to fourth motor drive, and on the aircraft breaks away from the guide rail car and flies to electric automobile, the aircraft passed through the second electro-magnet of undercarriage lower extreme and inhales tightly on the metal car shell at electric automobile top simultaneously.
The aircraft provides drive power through the last drive fan in the fan installation department, the partial air current that goes up the drive fan and produce blows off downwards from the air-out gap of each air-out ring, and combine the air-out speed of every air-out ring of adjusting part adjustment, thereby realize the horizontal flight or the turn to of aircraft, because each air-out ring that is located the aircraft periphery only plays the effect of adjustment aircraft gesture, the fan that does not have the power that provides, be difficult for resulting in the aircraft out of control or produce the injury to people or animals when air-out ring produces the touching with the foreign object, and the security is good. The appearance of the aircraft is similar to that of a four-shaft aircraft, and the four air outlet rings only have the function of adjusting the attitude, so that the aircraft is essentially a single-shaft aircraft.
Furthermore, the air current of air-out gap spun of air-out ring can flow along the water conservancy diversion wall according to the principle of coanda, forms a conical wind membrane, and conical wind membrane can drive the air of air-out ring internal week and flow downwards in the lump, and when the part of air-out gap received blockking in-process air-out gap of aircraft flight like this, the whole air current that the air-out gap formed influences for a short time, is favorable to the stability of aircraft flight gesture.
Furthermore, the axial direction of the air ring is perpendicular to the radial direction of the fan mounting part, an included angle of 5-20 degrees is formed between the axial direction of the air outlet ring and the horizontal direction, and the horizontal wind force generated by the wind blown out from the air outlet gap of the air outlet ring is opposite to the rotating direction of the fan blade of the upper driving fan. Through the design, the wind energy blown out from the wind outlet gap of the wind ring can counteract the reaction force generated when the upper driving fan or the upper driving fan and the lower driving fan rotate; and the air outlet speed of the air outlet ring is changed by adjusting the adjusting components at the same time, so that the integral forward rotation or reverse rotation of the aircraft can be realized. The air outlet speed of one or two air outlet rings can be adjusted by adjusting one or two adjusting components, so that the whole aircraft can be in an inclined state, and the aircraft can be driven to fly in the horizontal direction.
The undercarriage correspondingly retracts or expands along with the rising and falling of the aircraft, when the aircraft is in a flight state, the air pressure in the air outlet ring enables the piston and the sliding pipe to move towards one end of the sealing cap, so that the sliding pipe drives one end of the connecting rod to move towards the direction of the sealing cap, the lower end of the supporting rod also rotates towards one end of the sealing cap, and the undercarriage is in a retracting state. When the aircraft descends, the air pressure in the air outlet ring is reduced, the spring drives the sliding pipe to move towards the direction of the hinged seat together with the piston, so that the sliding pipe drives one end of the connecting rod to move towards the direction of the hinged seat, the lower end of the supporting rod is rotated to the limit position towards one end of the hinged seat, and the undercarriage is in an unfolding state.
The bar mouth plays the effect of restriction articulated joint on the slip pipe, and the position of bar mouth tip just makes the spring extension back, and the bracing piece rotates and continues to rotate 3-10 degrees after perpendicular with the horizontal direction for after the aircraft falls, each bracing piece all is in stable state.
