Description

Technical Field

[0001] The present invention relates to a power generation device, in particular to a wheel-ring type high-efficiency power generation device in which the magnet blocks of the rotor are arranged at an angle and the coil windings of the stator are wound in the same direction and overlap each other to generate 30-50% more induced current, making it suitable for electric vehicles. Background Art

[0002] Electric vehicles use battery power to drive the motor to drive the vehicle forward. Since electric vehicles do not cause air pollution, they will become increasingly popular based on the need for environmental protection. However, the endurance of electric vehicles is limited by the capacity and efficiency of the battery. If the power is insufficient, the vehicle will not be able to drive. In addition, the generator inputs kinetic energy through the power shaft, and uses the permanent magnets on the rotor to interact with the coils of the corresponding stator group to generate electrical energy for the application end. Since the moving axle has kinetic energy, installing a generator on the axle and sending the generated electricity to the battery to extend the use time of electricity has become a technology that needs to be actively developed in the field of electric vehicles.

[0003] Figure 1 As shown in the figure, it is the winding structure of the power generation coil of a general electric vehicle; wherein, the three groups of wires 811 / 812 / 813 are respectively wound around the first group of wire racks for several turns, and then wound around the second group of wire racks for several turns, and then wound around the third group of wire racks to form three groups of coils 801 / 802 / 803; however, it is found that the problem with the above winding method is that when the S magnetic pole 860 and the N magnetic pole 870 successively sweep over the coils 801 / 802 / 803, the coils 801 / 802 / 803 will produce a magnetic attraction, and the magnetic attraction will be greater when the voltage increases; therefore, winding separately will increase the magnetic attraction load in the power generation process, thereby affecting the power generation efficiency of the electric vehicle.

[0004] The inventor has considered that the coils in the existing electric vehicle generator are wound separately, which will lead to low power generation efficiency. Therefore, how to improve the winding method of the coil winding body to reduce the magnetic attraction load during the power generation process has become a topic that the inventor actively considers and wants to break through. Summary of the invention

[0005] The main technical problem to be solved by the present invention is to overcome the above-mentioned defects of the prior art and provide a ring-type high-efficiency power generation device, by adopting an oblique angle configuration of the rotor magnet block and a synchronous and unidirectional winding method of the coil winding to reduce the magnetic attraction load, thereby improving the power generation efficiency; by increasing the rotor speed through the transmission of the planetary gear set, and combining the oblique angle configuration of the rotor magnet block and the cyclic winding of the stator coil winding, the power generation efficiency of the electric vehicle is improved.

[0006] The technical solution adopted by the present invention to solve its technical problem is: A ring-type high-efficiency power generation device, comprising: a central axis, both ends of which are fixed on a frame, and one end of which is provided with a wire hole; a power source, pivotally mounted on the other end of the central axis, connected to an external transmission power and rotating on the central axis; a rotor, provided with an axial hole so that it is pivotally mounted on the outer edge of the central axis, and connected to the power source and rotates with it, a plurality of magnet blocks are arranged on the periphery of the rotor, the plurality of magnet blocks are parallel to each other and are arranged at an angle of 10 to 20 degrees to the axial direction, and adjacent magnetic poles are different; a stator, having an outer cover, a winding frame, and at least two sets of coil windings, wherein the outer cover is a disk structure with an axial hole, the coil The winding body is wound in a circular manner with a conductor in the same direction for several turns, and the number of turns wound continuously is at least 12, and a plurality of axially offset concave folded edges and convex folded edges are formed, and the concave folded edges and convex folded edges of the coil winding body are intertwined and stacked into one body; in addition, the winding frame is made of insulating resin and is an annular structure with through holes, and its periphery forms an array of annular cavities, and the stacked coil winding body is covered and positioned in the cavities of the winding frame; the winding frame is locked to the inner side surface of the disk structure of the outer cover, and the outer cover is sleeved on the outer edge of the central axis, so as to form the combined structure of the stator.

[0007] Then the rotor is placed in the through hole of the winding frame, and the coil winding body is arranged around the outer side of the magnet block with a gap therebetween, and each group of coil winding bodies forms an AC wire that passes through the wire hole of the central axis to the outside; thereby, the power source drives the rotor to rotate by transmitting power from the outside, and the magnet block on the periphery of the rotor will be displaced relative to the coil winding body, thereby causing the coil winding body to sense the change in the magnetic field and generate an induced current, which is then transmitted to the outside through the AC wire.

[0008] According to the aforementioned features, the present invention also includes: left and right frame covers, which are respectively pivotally mounted on the outer edge of the central axis and locked to the front wheel steel ring of the electric vehicle, so that the left and right frame covers will rotate following the movement of the front wheel of the electric vehicle; a planetary gear set, which is assembled on the inner side of the right frame cover, and has a central gear, a plurality of planetary gears, an annular internal gear and a gear fixing plate; the gear fixing plate is sleeved on the outer edge of the central axis, the annular internal gear has a plurality of internal teeth, and is connected to the right frame cover and rotates therewith, the plurality of planetary gears are arranged at equal angles and embedded in the receiving hole provided on the gear fixing plate, and each of them has a plurality of external teeth meshing with the internal teeth of the annular internal gear The central gear is pivotally mounted on the outer edge of the central axis and has a plurality of external teeth meshing with the external teeth of the plurality of planetary gears; wherein the front wheel rim of the electric vehicle forms the frame, the front wheel of the electric vehicle forms the external transmission power, the central gear in the planetary gear set forms the power source, and the rotor is connected to the central gear and rotates with it; thereby, the front wheel of the moving electric vehicle will drive the left and right side frame covers to rotate, and then through the transmission of the planetary gear set, the central gear will increase the speed to drive the rotor to rotate, and the rotor will further cause the coil winding to generate an induced current and transmit it to the battery to extend the power usage time of the electric vehicle.

[0009] Epicyclic Gearing is a type of gear structure, usually composed of one or more external gears rotating around a central gear, just like a planet orbiting the sun, hence the name. In addition, there is usually an outer ring gear on the outermost part of the planetary gear to fit the orbit of the planetary gear; because the planetary gear is a pure torque transmission, it has excellent transmission torque and very stable power output, so the planetary gear can provide a very high power transmission ratio.

[0010] With the aforementioned features, the "ring-type high-efficiency power generation device" of the present invention has the following benefits: (1) In the present invention, the magnet blocks of the rotor are arranged at an angle of 10-20° to the axial direction, and the adjacent magnetic poles are different; and the stator has at least two groups of coil windings, and the conductors are wound in a circular manner with at least 12 turns in the same direction, and are interlaced and stacked to form a whole; and the magnet blocks are arranged at the outer edge of the coil windings and separated by a gap, so that the rotation of the rotor will cause the magnet blocks to move relative to the coil windings and cut the magnetic lines of force, and in the process of cutting the magnetic lines of force, the amount of induced current that cancels each other out can be reduced. Since the approach area of ​​the coil windings and the magnet blocks is larger than the separation area, the magnetic group interference between the coil windings and the magnet blocks will be reduced, thereby obtaining a greater power generation efficiency.

[0011] (2) The present invention further utilizes the transmission of a planetary gear set to increase the rotation speed of the rotor equipped with a magnet block by several times relative to the rotation of the front wheel. The rotation of the rotor will cause the magnet block to generate 30-50% more induced current relative to the coil winding, thereby achieving high-efficiency power generation benefits.

[0012] The beneficial effect of the present invention is that the magnet blocks of the rotor are arranged at an oblique angle, and the coil windings are wound in a synchronous and unidirectional manner to reduce the magnetic load, thereby improving the power generation efficiency; the rotor speed is increased through the transmission of the planetary gear set, and the oblique angle arrangement of the rotor magnet blocks and the cyclic winding of the stator coil windings are combined to improve the power generation efficiency of the electric vehicle.

[0028] First, see Figure 2~Figure 5 1 is a structure 100 of a first embodiment of a ring-type high-efficiency power generation device of the present invention, comprising: a central shaft 10, both ends of which are fixed on a frame (not shown), and one end of which is provided with a wire hole 11; a power source 21, which is provided with a center hole 211 and pivotally mounted on the other end of the central shaft 10 with a ball bearing 12, and the power source 21 is connected to an external transmission power (not shown) and rotates on the central shaft 10; a rotor 30, which is provided with an axial hole 32 and pivotally mounted on the outer edge of the central shaft 10 in combination with the ball bearing 12, and is connected to the power source 21 so that the rotor 30 rotates therewith, and a plurality of magnet blocks 31 are respectively fixed to the periphery of the rotor 30 with countersunk screws 33, and the plurality of magnet blocks 31 are parallel to each other and arranged at an oblique angle θ to the YY axis (please also refer to Figure 6C , Fig.6D ), wherein the bevel angle θ in the present invention is configured to be between 10 and 20°, and the preferred bevel angle θ is 15°; furthermore, the adjacent magnetic poles of the several magnet blocks 31 are different, that is, the magnetic poles of the several magnet blocks 31 are arranged in the order of N, S, N, S, N, S...

[0029] The stator 40 comprises an outer cover 41, a winding frame 42, and at least two sets of coil winding bodies 43, wherein the outer cover 41 is a disk structure having an axial hole 411, and the coil winding body 43 is wound with a wire 431 for several turns in the same direction, and the number of turns wound continuously is at least 12 turns, and a plurality of axially displaced concave folded edges 432 and convex folded edges 433 are formed, and the concave folded edges 432 and convex folded edges 433 of the coil winding body 43 are mutually inserted and overlapped, that is, the concave folded edge 432 of the first coil winding body 43A overlaps the concave folded edge 432 of the second coil winding body 43B, and the second coil winding body 43A is overlapped with the concave folded edge 432 of the second coil winding body 43B. The convex folded edge 433 of 3B is inserted into the convex folded edge 433 of the first coil winding body 43A, and the insulating resin is partially covered and positioned by the injection molding machine and the mold. Then, the insulating resin will form the winding frame 42, and the formed winding frame 42 is an annular structure with a through hole 421, and its periphery forms an array of annular cavities 422 and ribs 423; the convex folded edge 433 of the stacked coil winding body 43 will be covered in the cavity 422 of the winding frame 42, and the concave folded edge 432 will be overlapped outside the rib 423 of the winding frame 42, as shown in FIG. Figure 3 and then the winding frame 42 is locked to the inner side of the outer cover 41 by screws 45, thereby forming a combined structure of the stator 40, the combined state of which is as shown Figure 4 shown.

[0030] Based on the above, the outer cover 41 is sleeved on the outer edge of the central axis 10, and the rotor 30 is placed in the through hole 421 of the winding frame 42, and the coil winding body 43 is arranged around the outer side of the magnet block 31 and is separated from it by a gap G, and each group of coil winding bodies 43 respectively forms an AC wire 44 that extends to the outside through the wire hole 11 of the central axis 10. The combined structure is shown in FIG. Figure 5 shown.

[0031] Please continue reading Figure 6A~6E, which is the configuration state of the magnet block 31 and the coil winding body 43 of the rotor 30 of the present invention; wherein, the rotor 30 is connected to the power source 21 and rotates therewith, and a plurality of magnet blocks 31 are arranged at the periphery of the rotor 30, and the plurality of magnet blocks 31 are parallel to each other and arranged at an oblique angle θ to the YY axis; the inventor has found through testing that when the magnet blocks 31 at the periphery of the rotor 30 are arranged at an oblique angle θ, the magnetic load can be reduced and the induced current can be increased in the process of cutting the magnetic lines of force with the coil winding body 43, but when the oblique angle θ of the magnet block 31 is less than 10°, the magnetic load is reduced. The effect of lightness is limited; and when the oblique angle θ of the magnet block 31 is greater than 20°, the currents induced by the adjacent magnet blocks 31 will cancel each other out, thereby reducing the power generation efficiency; therefore, the oblique angle θ of the magnet block 31 in the present invention is preferably set between 10 and 20°, and the preferred oblique angle θ is 15°; furthermore, the magnet blocks 31 adjacent to the periphery of the rotor 30 need to maintain a spacing D, and the spacing D is set according to the length of the magnet block 31, which is 2 to 7 mm to avoid mutual interference; and the adjacent magnetic poles need to be different, that is, arranged in sequence in an interlaced manner of N, S, N, and S. In this embodiment, the magnet block 31 is different from the generally commercially available rectangular magnet blocks, such as Figure 6B , Fig.6D , Fig. 6E As shown, the front and rear ends 34 of the magnet block 31 are parallel to each other and perpendicular to the YY axis, and the left and right sides 35 are also parallel to each other and are arranged at an oblique angle θ with the YY axis. Furthermore, the upper and lower surfaces of the magnet block 31 match the outer edge shape of the rotor 30 to form a curved surface 36; accordingly, the magnet block 31 forms a slightly twisted shape front and back, and can then fit closely on the outer edge surface of the rotor 30 to be firmly positioned, and the oblique angle θ and the spacing D can be accurately arranged.

[0032] In the stator 40 structure of the present invention, the coil winding body 43 is set to two groups, including a first coil winding body 43A and a second coil winding body 43B; and the two wires 431 thereof are respectively wound in a synchronous and unidirectional circular winding manner, and the number of turns of the two wires 431 respectively wound continuously is at least 12 turns; and the overlapping method of the coil winding body 43 is that the concave folded edge 432 of the first coil winding body 43A is overlapped on the outer side of the concave folded edge 432 of the second coil winding body 43B, and the convex folded edge 433 of the second coil winding body 43B is inserted into the inner side of the convex folded edge 433 of the first coil winding body 43A; further, the coil winding body 43 is arranged around the The outer side of the magnet block 31 is separated from the magnet block 31 by a gap G. Since the rotor 30 is rotated by the power source 21, the magnet block 31 at the periphery of the rotor 30 will be displaced relative to the coil winding 43, thereby causing the coil winding 43 to sense the change in the magnetic field and generate an induced current. Since the magnet block 31 is arranged at an angle of 10 to 20 degrees to the YY axis, the amount of induced current that cancels each other out can be reduced during the process of cutting the magnetic lines of force. Moreover, since the approach area of ​​the coil winding 43 and the magnet block 31 is larger than the separation area, the magnetic group interference between the coil winding 43 and the magnet block 31 can be reduced, thereby obtaining a greater power generation benefit.

[0033] Furthermore, the two conducting wires 431 of the coil winding body 43 are wound in a synchronous and unidirectional manner. Therefore, when the N pole of the magnet block 31 synchronously sweeps across the coil winding body 43, its driving potential is in the same direction and cooperates with the number of poles to produce a synchronous effect; and at this time, the S pole is just in the opposite direction of the arrangement, and its driving potential direction is exactly the same as that of the N pole, thereby forming a larger coil winding body 43 circulation loop; and because the magnetic field effect generated by the charged coil winding body 43 has been dispersed in the circulating wire bundle, the magnetic effect area is reduced, and the magnetic attraction load caused by the concentration of the magnetic attraction field effect is reduced, thereby increasing the efficiency of power generation.

[0034] Figure 7As shown, the structure 200 of the second embodiment of the wheel-ring type high-efficiency power generation device of the present invention is the same as the structure of the first embodiment, represented by the same figure number, and the difference is: the present embodiment also includes a central shaft 10, left and right frame covers 51 / 52, a planetary gear set 20, a rotor 30, and a stator 40; wherein the central shaft 10 is fixedly arranged at the center of the front wheel steel ring 53 of the electric vehicle, and one end of the central shaft 10 is provided with an L-shaped wire hole 11, the inlet end of the wire hole 11 is arranged at its radial outer edge, and the outlet end is located at the end face of one side of the axial direction; the left and right frame covers 51 / 52 are respectively pivotally arranged at the outer edge of the central shaft 10 by ball bearings 12, and are locked at the front wheel steel ring 53 by screws 13, so that they rotate with the movement of the front wheel of the electric vehicle; the planetary gear set 20 is arranged at The inner side of the left frame cover 51 has a central gear 21', several planetary gears 22, an annular internal gear 23 and a gear fixing plate 24; wherein the annular internal gear 23 is connected to the left frame cover 51 by a countersunk screw 14 and rotates therewith, and the central gear 21' is pivoted on the outer edge of the central axis 10 by a ball bearing 12; further, the rotor 30 is provided with an axial hole 32, and its two ends are pivoted on the outer edge of the central axis 10 by a ball bearing 12, and several magnet blocks 31 are provided at the periphery of the rotor 30, and are connected to the central gear 21' by a long screw 37 and rotate therewith; since the "planetary gear" group has the function of increasing speed, the rotor 30 connected to the central gear 21' can achieve an effect of increasing speed several times compared to the front wheel rim 53.

[0035] Furthermore, the stator 40 has an outer cover 41, a winding frame 42, and at least two groups of coil windings 43, wherein the coil windings 43 are wound in a circular manner with several turns in the same direction, and the coil windings 43, the winding frame 42, and the frame cover 41 are combined to form the stator 40 structure, and the rotor 30 is placed in the through hole 421 of the winding frame 42, and the coil windings 43 and the magnet block 31 are separated by a gap G. The above-mentioned first embodiment is similar to the above-mentioned details, so the details are not repeated. In this embodiment, since the central gear 21' increases the speed to drive the rotor 30 to rotate, the magnet block 31 on the periphery of the rotor 30 will be displaced relative to the coil windings 43, thereby causing the coil windings 43 to sense the change in the magnetic field and generate an induced current, and the induced current is then guided to the outside from the wire hole 11 through the AC conductor 44.

[0036] The second embodiment of the present invention has a planetary gear set 20 in structure 200, and its structure is as follows: Figure 8 As shown, the left frame cover 51 is assembled on the inner side thereof, and has a central gear 21', a plurality of planetary gears 22, an annular internal gear 23 and a gear fixing plate 24; wherein the annular internal gear 23 is connected to the left frame cover 51 by a countersunk screw 14 and rotates with the front wheel steel ring 53, and the central gear 21' is pivotally mounted on the outer edge of the central shaft 10 by a ball bearing 12, and is connected to the rotor 30 by a long screw 37 to drive it to rotate (see Figure 7 ); In the present invention, the number of the planetary gears 22 is three, and they are arranged at an equal angle of 120° to each other; furthermore, the inner teeth 27 of the annular internal gear 23 is set to 96 teeth, and the outer teeth 28 of the planetary gears 22 and the central gear 21' are set to 30 teeth, then through the speed-increasing effect of the "planetary gears", the central gear 21' will produce a 3.2-fold accelerated rotation effect relative to the front wheel rim 53; the second embodiment 200 of the present invention, through the transmission of the planetary gear set 20, enables the rotor 30 provided with a plurality of magnet blocks 31 to increase the rotation speed by several times relative to the rotation of the front wheel rim 53, and then the coil winding body 43 is used to reduce the magnetic load in a synchronous and unidirectional circular winding manner, and the induced current is increased by 30~50% of the voltage / current, so as to increase the efficiency of its power generation device.

[0037] Fig. 9FIG. 2 is an application state of the second embodiment of the present invention, wherein the second embodiment structure 200 is installed at the front wheel 303 of the electric vehicle 300; since the front wheel 303 has no other functions except controlling the balance and direction of the electric vehicle 300 and coordinating the brakes during the movement, and the front wheel 303 of the electric vehicle 300 generates a large torque force during the movement of the electric vehicle 300, the application of the torque force can enable the second embodiment structure 200 to generate electricity; furthermore, the electric vehicle 300 is also equipped with a rectifier device 320 and a power storage device 33 0, a motor driver 340, and an electric vehicle motor 350; in the application of this embodiment, the rectifier 320 is installed on the front side of the body 301 of the electric vehicle 300, and is connected to the aforementioned AC wire 44, so that the induced current generated by the coil winding 43 is transmitted to the rectifier 320; since the power generation power will change with the rotation speed of the front wheel 303, the rectifier 320 can convert the unstable AC voltage output by the structure 200 of the second embodiment into a stable DC power; the power storage device 330 has The capacitor unit 331 and the battery unit 332 connected in series therewith are installed under the pedal 302 of the body 301 of the electric vehicle 300, and the input end thereof is connected to the output end of the rectifier 320 via a charging input line 333, wherein the capacitor unit 331 can be charged quickly and discharged slowly; the battery unit 332 receives and stores the power discharged by the capacitor unit 331; the present invention uses the fast power storage function of the power storage device 330 to enable the electric vehicle 300 to be charged quickly and discharged slowly, whether in a moving state or a parking state. , and its charging operation is in progress uninterruptedly, so the power storage device 330 will be able to improve the driving efficiency of the electric vehicle 300; the motor driver 340 is installed on the rear side of the body 301 of the electric vehicle 300, and its input end is connected to the output end of the power storage device 330 through a current output line 341 to convert the input constant voltage current into a variable voltage current, which is then transmitted via a transmission line 342 to drive the electric vehicle motor 350 at the rear end to drive its rear wheel 304 to rotate, and achieve the effect of controlling its torque and speed.

[0038] In the present invention, the magnet blocks 31 of the rotor 30 are arranged at an angle θ of 10-20° with the axial direction, and the adjacent magnetic poles are different; and the stator 40 has at least two groups of coil windings 43, and the conductors 431 thereof are wound in a circular manner in the same direction for at least 12 turns, and are interlaced and stacked to form a whole; and the magnet blocks 31 are arranged at the outer edge of the coil windings 43 and are separated by a gap G. Then, when the rotor 30 rotates, the magnet blocks 31 will be displaced relative to the coil windings 43 to cut the magnetic lines of force, and in the process of cutting the magnetic lines of force, the amount of induced current that cancels each other out can be reduced. Since the approaching area of ​​the coil windings 43 and the magnet blocks 31 is larger than the separation area, the magnetic group interference between the coil windings 43 and the magnet blocks 31 will be reduced, thereby obtaining a greater power generation efficiency. Furthermore, the present invention also uses the transmission of the planetary gear set 20 to make the rotor 30 equipped with the magnet block 31 generate a rotation speed 3.2 times that of the rotation of the front wheel rim 53. The rotation of the rotor 30 will cause the magnet block 31 to generate 30~50% more induced current relative to the coil winding 43, thereby achieving high-efficiency power generation benefits.
