Said wind airfoil assembly comprises four hollow wind wings 1,2,3,4, wind wing axle 5 and is fixed on the swiveling wheel 6 on the wind wing axle that this wind airfoil assembly is installed in the anterior air intake position of vehicle; Four hollow wind wings 1,2,3,4 are the hollow-core construction of strip; The both sides of elongate body are identical non-linear semiellipse type curve form; The curvature of its front end is bigger; The curvature of rear end is less, and four hollow wind wings are by upper and lower, forward and backward position, all side that be distributed on swiveling wheel 6 parallel with wind wing axle 5; The driving shaft of said generator 8,9 is coaxial the connection with wind wing axle 5; Said generator 8,9 is connected with batteries with dc bus through charging device, and the load of vehicle is parallelly connected relation with storage battery.Said generator is a pair of 8,9, directly is coupling on the adpting flange 7 at wind wing rotating shaft 5 two ends.
Protection range of the present invention not only is confined to above-mentioned embodiment, and other people make the improvement of non-intrinsically safe property, all belong within protection scope of the present invention.
The floating charge characteristic that the present invention is alleged: batteries is the stand-by power supply of the vehicle-mounted direct current system of pure electric vehicle electric power.The floating charge line feature is that battery pack is connected on the load circuit with the floating machine power circuit parallelly connectedly.Under normal running status, the charging device that links to each other with dc bus except that to the conventional load power supply, also provides floating current to batteries, and this operational mode is called full floating charge working method, is called for short floating charging operation.Floating charge is the electric mode of a kind of confession (putting) of batteries; System is parallel-connected to batteries and floating machine power circuit on the load circuit; His voltage is constant substantially; Only a little more than the terminal voltage of batteries, the little current that is supplied by the floating machine power circuit compensates the loss of batteries local action, satisfies state and unlikely overcharging so that it can often remain on charging.Therefore; Batteries can fluctuate up and down and discharges and recharges with the floating machine power line voltage; When the light and floating machine power line voltage of load was higher, batteries was promptly charged, when heavier or floating machine power supply takes place to interrupt when load; Batteries is then discharged, and shares part or all of load.Like this, batteries just plays pressure stabilization function, and is in stand-by state.The floating charge power supply working method can be divided into partial floating and two kinds of full floating charges.When part-time (when floating machine receives under the simultaneous force effect to start rotation) carries out floating charge power supply, and part-time (during the floating machine stall) is called the partial floating working method, or is claimed regularly full floating charge working method by the batteries working method of power supply separately in addition.If All Time then is called full floating charge working method by the parallelly connected floating charge power supply with batteries of floating machine power circuit, or claim continuous floating charge working method.
With the batteries that the floating charge working method is used, its life-span, general full charge and discharge system person will grow, and the batteries that can use more less capacity instead replaces.
The simultaneous force that the present invention is alleged, in aerodynamics, Nonlinear Elliptic Partial Differential Equation theory and approximation method; Through experiment and observation; Flow phenomenon and mechanism are analyzed, proposed the proper mechanical model, participate in Fig. 1, Fig. 2, Fig. 3, Fig. 4; This model is followed: the kinematics aspect, follow mass conservation law; Newton's second law is followed in the dynamics aspect; Law of conservation of energy is followed in power conversion and transmission aspect.Thermodynamics first and second laws are followed in the thermodynamics aspect.Corresponding gas state equation and viscosity are followed in the media property aspect, the Changing Pattern of thermal conductivity etc.The hollow wind wing passes in the air that goes separates air-flow, and referring to Fig. 1, portion of air flows through from hollow wind wing top, and another part flows through from the below.Flowing of air is invisible in daily life; But flowing of low speed flow has bigger similitude with current; The daily experience of life is told us, and is when current flow through the riverbed with a metastable flow, slow at the local flow velocity of river surface broad; The local flow velocity narrower in the riverbed is very fast, and the air-flow and the flowing water in the river that flow through the hollow wind wing are similar.
Because the hollow wind wing is asymmetric, the curvature of its front end is bigger, and the curvature of rear end is less; The air-flow that flows through hollow wind wing upper surface just is similar to the flowing water in narrower place, and flow velocity is very fast, and the air-flow that flows through below the hollow wind wing is just in time opposite; Be similar to the local flowing water of broad, flow velocity is slow than the air-flow of upper surface, according to hydromechanical basic principle; The slow atmospheric pressure that flows is bigger; And the fast atmospheric pressure that flows is less, and the pressure of the hollow like this wind wing lower surface just pressure than upper surface is high, in other words; Be exactly that the atmosphere pressure that puts on hollow wind wing lower surface (direction make progress Fig. 1) is bigger than the pressure (being directed downwards Fig. 1) that puts on hollow wind wing upper surface, the pressure differential of the two just formed the hollow wind wing when axle horizontal before the wind wheel wing produce lift.Fig. 1, the hollow wind wing is opposite with above-mentioned principle behind axle horizontal, produces decline power, participates in Fig. 2.
The hollow wind wing produces the reason of lift and decline power, in simple terms, motor vehicle to overtake fast more; The aerodynamic force that the hollow wind wing produces is also just big more; When lift (shown in Figure 1) and decline power (shown in Figure 2) greater than generator field power when (being called gravity), just can synchronous generator, when lift (shown in Figure 1) and decline power (shown in Figure 2) less than generator field power when (being called gravity); The hollow wind wing when axle is vertical; Participate in Fig. 3,, produce thrust by the forward action power of motor vehicle.
When axle was vertical, the following hollow wind wing was referring to Fig. 4, and the symmetrical air-flow in certain inclination angle (being called the angle of attack or the angle of attack) is separated and flow through and produce a vortex system 10 at hollow wind wing afterbody; (being called Karman vortex street); Will produce the backflow pulse, go into Hui Li, referring to Fig. 4.
According to the physical law of above-mentioned aspect, pure electric vehicle is resistance zuli to overtake, the air-flow of active force backward that air produces; Floating stressed synchronously through hollow wind wing Fig. 1, Fig. 2, Fig. 3, Fig. 4, be a new subject, i.e. mechanics synchronously; It is an aerodynamic branch; It mainly studies floating object, is making floating mechanical characteristic under the relative motion situation with gas, gas flow rule and physics, the chemical change of following generation.It is the new subject that development is grown up on the hydromechanical basis.Be meant that floating machine is installed in the anterior air intake position of pure electric vehicle, utilize the synchronous mechanics of generation that goes to convert air force into and can generate electricity, generally account for the anterior air intake of pure electric vehicle position≤75%.
Practical implementation of the present invention is exemplified below:
At first; With floating machine, be installed in the anterior air intake position of pure electric vehicle, when going above speed per hour of 40km/h and wind speed 19-20m/s approximately by pure electric vehicle; Four hollow wind wings; Before hollow wind wing A, go up hollow wind wing B, the hollow wind wing C in back, hollow wind wing D down, receive to start the simultaneous force effect under rotation drive generator for electricity generation, the load and the batteries floating charge work of pure electric vehicle are provided.
