Detailed Description

As shown in fig. 1 to 4, the vehicle-mounted wind-driven integrated generator comprises an air inlet part 1, an air outlet part 2, a rotor 3 and a stator 4, wherein:

the air inlet part 1 and the air outlet part 2 form an outer shell of the integrated generator, and after being butted, the air inlet part and the air outlet part form a space A for accommodating the rotor 3 and the stator 4;

the air inlet part 1 comprises an air inlet shell 11 with an air inlet 111 (generally horn-shaped), a plurality of air inlet guide plates 12 radially arranged in the air inlet 111, and a generator shaft seat I13 connecting the inner ends of all the air inlet guide plates 12 into a whole; it is known that when the moving air flow (wind) blows on the blades, it is split into two forces, one being radial thrust and the other being rotational moment, while radial thrust is idle, and only increasing the rotational moment can increase the output of the generator. The method for increasing the rotation moment is to make the included angle between the blades and the direction from the air flow become larger, and to reduce the axial thrust and increase the rotation moment, the included angle between the air flow and the rotation of the blades becomes smaller, so that: the air inlet guide plate 12 comprises an outer end plate 121 parallel to the air flow direction of the air inlet 111 and an inner end inclined plate 122 forming an included angle with the outer end plate 121; the inner end swash plate 122 will act at a greater angle on the windward side 321 of the blades of the rotor 3 after the wind coming from the inlet 111 is redirected. It is known that the air flow generated by the fast-moving automobile is aligned with the forward direction of the automobile, the natural wind direction is uncertain, and the superposition of the two air flows makes the air flow have a somewhat disordered moving direction at the initial stage of touching the forward object when the automobile advances, and at this time, the outer end plate 121 of the air inlet guide plate 12 functions to sort the air flows into an air flow completely opposite to the forward direction of the automobile; after the air flow rapidly passes through the outer end plate of the guide plate, the direction of the air flow is changed by the inner end inclined plate 122 of the guide plate and acts on the windward side 321 of the blade of the rotor 3, so that the included angle of the inner end inclined plate 122 acting on the blade 32 of the rotor 3 after the direction of the wind coming from the air inlet is changed is increased, and the wind energy coming in pushes the blade to rotate with larger torque with the largest force; (under the same condition, the kinetic energy of the air inlet guide plate is increased by more than 20 percent compared with that of the air inlet guide plate without the guide plate)

The air outlet part 2 comprises an air outlet shell 21 with an air outlet 211, a plurality of air outlet spoke plates 22 radially arranged in the air outlet 211, and a generator shaft seat II 23 which connects the inner ends of all the air outlet spoke plates 22 into a whole;

the rotor 3 includes an annular rotor housing 31, a plurality of blades 32 provided on the outer peripheral wall of the rotor housing 31, and an annular permanent magnet fitted tightly inside the rotor housing 3133The method comprises the steps of carrying out a first treatment on the surface of the The blades 32 are tile-shaped and have a windward side 321 adopts a zigzag structure;

the stator 4 includes a central shaft 41, a silicon steel sheet 42 sleeved outside the central shaft, and a coil 43 wound in the silicon steel sheet 42; after the stator 4 is sleeved in the rotor shell 31 of the rotor in a clearance fit manner, two ends of the central shaft 41 are fixedly arranged in the first generator shaft seat 13 of the air inlet part 1 and the second generator shaft seat 23 of the air outlet part 2 respectively, namely, the central shaft is connected with the first generator shaft seat 13 and the second generator shaft seat 23 of the air inlet part and the air outlet part in a non-rotatable manner; in this way, after the stator 4 is installed in the rotor housing 31 of the rotor 3, the rotor 3 and the stator 4 are installed in the space a enclosed by the air inlet portion 1 and the air outlet portion 2, and only two ends of the center shaft 41 are exposed and extend into the first engine shaft seat 13 of the air inlet portion 1 and the second engine shaft seat 23 of the air outlet portion 2, respectively.

The weight of the vehicle-mounted wind power integrated generator is less than 20 kg, and the weight of the vehicle-mounted wind power integrated generator accounts for a small proportion of the weight of the whole vehicle, so that the load of the vehicle is not increased; when the automobile engine is installed and used, the automobile engine is usually installed in a machine head below an engine cover, and the horn-shaped air inlet 111 of the automobile engine faces to the automobile grille, so that the overall appearance of the automobile is not affected, the running resistance (namely wind resistance) is increased, the automobile grille can be used for protecting the automobile engine, large foreign matters are prevented from entering the wind-driven integrated generator from the air inlet, and wind generated when the wind resistance (the wind coming from the grille of the existing automobile is directly blown into the machine head) is reduced, and the wind generated when the automobile runs fast is used for driving the generator to generate electricity. When the automobile is running, the wind power can be used for driving the generator to work: at this time, the vane 32 drives the permanent magnet 33 to rotate at a high speed, and generates induced electromotive force on the coil 43 to output electric energy; the coil 43, the silicon steel sheet 42 and the central shaft 41 are not rotated, unlike the existing vehicle-mounted wind power generator. Along with the increasing popularization of electric vehicles, the power generated by the vehicle-mounted wind power integrated generator can be stored in an energy storage battery of the electric vehicle in an external converter without additionally arranging a storage battery in the vehicle, so that the energy storage of the battery is increased, the electric energy of the electric vehicle in running is well supplemented, and the running mileage and the cruising ability of the vehicle are improved. The kinetic energy can be increased by about 10% at the speed of 100km per hour.

As can be seen from the above, since the housing part of the integrated generator is composed of the air inlet part 1 and the air outlet part 2, and they enclose a space a for housing the rotor 3 and the stator 4 after being butted, and the stator 4 is housed in the rotor housing 31 of the rotor 3, then both the stator 4 and the rotor 3 are mounted together in the space a enclosed by the air inlet part 1 and the air outlet part 2, thus forming an integrated, on-board wind power generator with a small volume; in addition, the air intake baffle 12 includes an outer end plate 121 parallel to the air flow direction and an inner end inclined plate 122 forming an included angle with the outer end plate 121, so that the inner end inclined plate 122 can act on the blades 32 of the rotor 3 at a larger or even a maximum angle after the direction of the air coming from the air inlet 111 is changed, thus the incoming air can push the rotor 3 to rotate with a larger torque with a maximum force, more electric energy is generated, and the power generation efficiency is improved.

Because the integrated generator has a compact structure and a small volume, when the integrated generator is installed in an automobile, the integrated generator can be fixed on the shell frame of the head of the automobile after penetrating through the through holes 212 of the bottom plate of the air outlet shell 21 by bolts, so that the integrated generator is very convenient to assemble, disassemble and maintain.

Preferably, the angle between the outer end plate 121 and the inner end inclined plate 122 is between 10 degrees and 40 degrees, which is often matched with the camber and the pitch of the blade in actual production.

In the present embodiment, bearings 5 are provided at both ends of the center shaft 41, the bearings 5 being provided in bearing mounting holes 61 of the cover plate 6; the cover plate 6 is provided with a heat radiation hole 62, and the cover plate 6 is fixed to the rotor 3 (here, to the rotor housing 31 of the rotor 3);

in the present embodiment, the accommodating portion of the space a where the rotor 3 and the stator 4 are installed is provided in the air outlet casing 21 of the air outlet portion 2, as shown in fig. 3; of course, it may also be provided in the air intake housing 11 of the air intake section 1.

Preferably, the outer peripheral wall of the generator shaft seat 13 of the air inlet portion 1 is tapered so that the wind coming in from the air inlet 111 acts on the blades 32 of the rotor 3 with a greater thrust.

In this embodiment, the air outlet spoke plate 22 of the air outlet portion 2 is flat.
