Description

Technical Field

[0001] The utility model relates to a power generation device, particularly a wheel-ring type high-efficiency power generation device in which the rotor magnet blocks are arranged at an angle and the stator coil windings are wound in the same direction and interlaced with 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, propelling the vehicle forward. Because electric vehicles do not contribute to air pollution, they are becoming increasingly popular due to environmental concerns. However, their range is limited by the battery's capacity and efficiency; insufficient power renders the vehicle inoperable. Furthermore, the generator inputs kinetic energy through the power shaft and generates electrical energy for the user through the interaction between the permanent magnets on the rotor and the corresponding coils in the stator assembly. Because the moving axle possesses kinetic energy, installing a generator on the axle and feeding the generated energy into the battery to extend the life of the vehicle has become a technology actively developed in the electric vehicle industry.

[0003] Figure 1 FIG. 1 shows the winding structure of a typical electric vehicle's generating coil. Three sets of wires 811, 812, and 813 are each wound around a first wire rack for several turns, then around a second wire rack for several turns, and then around a third wire rack to form three sets of coils 801, 802, and 803. However, a problem with the aforementioned winding method is that when the S magnetic pole 860 and the N magnetic pole 870 successively sweep across the coils 801, 802, and 803, magnetic attraction is generated by the coils 801, 802, and 803. Furthermore, the magnetic attraction increases as the voltage rises. Therefore, winding the wires separately will increase the magnetic load during the power generation process, thereby affecting the power generation efficiency of the electric vehicle.

[0004] The inventors have considered that the separate winding of coils in existing electric vehicle generators leads to low power generation efficiency. Therefore, how to improve the winding method of the coils to reduce the magnetic load during the power generation process has become a problem that the inventors actively consider and want to break through. Utility Model Content

[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 blocks and a synchronous and unidirectional winding method of the coil winding body, the magnetic attraction load is reduced, thereby improving the power generation efficiency. The rotor speed is increased through the transmission of the planetary gear set, and the oblique angle configuration of the rotor magnet blocks and the cyclic winding of the stator coil winding body are combined to improve the power generation efficiency of the electric vehicle.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A ring-type high-efficiency power generation device includes: a central shaft, both ends of which are fixed to 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 shaft, connected to an external transmission power and rotating on the central shaft; a rotor, provided with an axial hole so that it is pivotally mounted on the outer edge of the central shaft and connected to the power source and rotates with it, a plurality of magnet blocks are arranged on the periphery of the rotor, the magnet blocks are parallel to each other and 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 with a conductor in a circular manner in the same direction for several turns, and the number of consecutive turns is at least 12, forming a plurality of axially offset concave folds and convex folds, and then the concave folds and convex folds of the coil winding body are intertwined and stacked together to form a whole. In addition, the winding frame is made of insulating resin and has an annular structure with a through hole. The periphery forms an array of annular cavities, and the stacked coil winding body is enclosed and positioned in the cavities of the winding frame. The winding frame is locked to the inner side of the disk structure of the outer cover, and the outer cover is sleeved on the outer edge of the central axis to form the combined structure of the stator.

[0008] The rotor is then placed in the through-hole of the winding frame, and the coil windings are arranged around the outer side of the magnet block with a gap therebetween. Each set of coil windings forms an AC wire that extends through the wire hole of the central axis to the outside. In this way, the power source drives the rotor to rotate by transmitting power from the outside. The magnet blocks on the periphery of the rotor will be displaced relative to the coil windings, causing the coil windings to sense the change in the magnetic field and generate an induced current, which is then transmitted to the outside via the AC wire.

[0009] According to the aforementioned features, the present invention further includes: left and right frame covers, which are respectively pivotally mounted on the outer edge of the central shaft and locked to the front wheel steel rim of the electric vehicle, so that the left and right frame covers will rotate as the front wheel of the electric vehicle moves; 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 shaft, 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 accommodating hole provided on the gear fixing plate, and each of them has a plurality of external teeth that are mutually engaged 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.

[0010] Epicyclic Gearing is a type of gear structure that typically consists of one or more outer gears rotating around a central gear, much like planets orbiting the sun, hence the name. Additionally, the outermost gears often have an outer ring gear to match the orbital path of the planetary gears. Because epicyclic gears are pure torque transmissions, they offer excellent torque transmission and very smooth power output, enabling them to provide very high power transmission ratios.

[0011] With the aforementioned features, the present invention's "ring-type high-efficiency power generation device" has the following benefits:

[0012] (1) In the present invention, the rotor's several magnet blocks are arranged at an angle of 10 to 20 degrees to the axial direction, and the adjacent magnetic poles are different; and the stator has at least two groups of coil windings, whose conductors are wound in a circular manner with at least 12 turns in the same direction, and are interwoven 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 will 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.

[0013] (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.

[0014] The beneficial effect of the present invention is that the magnetic load is reduced by adopting an oblique angle configuration of the rotor magnet blocks and a synchronous and unidirectional winding method of the coil winding body, thereby improving the power generation efficiency; the rotor speed is increased through the transmission of the planetary gear set, and the oblique angle configuration of the rotor magnet blocks and the cyclic winding of the stator coil winding body are combined to improve the power generation efficiency of the electric vehicle.

[0087] First, see Figures 2 to 5 As shown, the structure 100 of the first embodiment of the ring-type high-efficiency power generation device of the present invention includes: a central shaft 10, both ends of which are fixed to 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 is 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 a shaft hole 32 and is pivotally mounted on the outer edge of the central shaft 10 in conjunction with the ball bearing 12, and is connected to the power source 21 so that the rotor 30 rotates therewith, and several magnet blocks 31 are respectively locked to the periphery of the rotor 30 with countersunk screws 33. The several magnet blocks 31 are parallel to each other and are arranged at an oblique angle θ to the YY axis (please also refer to Figure 6C 、 Figure 6D ), wherein the bevel angle θ in the present invention is configured to be between 10 and 20 degrees, and the preferred bevel angle θ is 15 degrees; furthermore, the adjacent magnetic poles of the plurality of magnet blocks 31 are different, that is, the magnetic poles of the plurality of magnet blocks 31 are arranged in the order of N, S, N, S, N, S...

[0088] 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. The coil winding bodies 43 are wound with a wire 431 for a plurality of turns in the same direction, and the number of turns wound continuously is at least 12 turns, and a plurality of axially offset concave folded edges 432 and convex folded edges 433 are formed. The concave folded edges 432 and convex folded edges 433 of the coil winding body 43 are then interwoven 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 43B is wound with a wire 431. 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 injection molding equipment and molds. The insulating resin will then form the winding frame 42. 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 laminated 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 of the disk structure by screws 45, thereby forming a combined structure of the stator 40, which is a combined state as shown Figure 4 shown.

[0089] Continuing with the above, the outer cover 41 is sleeved on the outer edge of the central shaft 10, and the rotor 30 is placed in the through hole 421 of the winding frame 42, and the coil windings 43 are arranged around the outer side of the magnet block 31 and separated from it by a gap G. Each set of coil windings 43 forms an AC wire 44 that extends through the wire hole 11 of the central shaft 10 to the outside. The combined structure is shown in FIG. Figure 5 shown.

[0090] Please continue reading Figures 6A-6E 3. The figure shows the configuration of the magnet blocks 31 and the coil windings 43 of the rotor 30 of the present invention. The rotor 30 is connected to the power source 21 and rotates therewith. Several magnet blocks 31 are provided on the periphery of the rotor 30. The magnet blocks 31 are parallel to each other and are arranged at an angle θ to the YY axis. The inventors have found through testing that when the magnet blocks 31 on the periphery of the rotor 30 are arranged at an 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 windings 43. However, when the angle θ of the magnet blocks 31 is less than 10°, the magnetic load is reduced. The light effect is limited; and when the bevel 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 bevel angle θ of the magnet block 31 in the present invention should be set between 10 and 20°, and the preferred bevel angle θ is 15°; furthermore, the adjacent magnet blocks 31 on 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, S. In this embodiment, the magnet block 31 is different from the generally commercially available rectangular magnet blocks, such as Figure 6B 、 Figure 6D 、 Figure 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, while 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 curved surfaces 36. Accordingly, the magnet block 31 forms a slightly twisted shape front to back, thereby tightly fitting the outer edge surface of the rotor 30 and firmly positioning it, and accurately configuring the oblique angle θ and the spacing D.

[0091] In the stator 40 structure of the present invention, the coil winding body 43 is set as 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 outside 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 inside of the convex folded edge 433 of the first coil winding body 43A; furthermore, the coil winding body 43 is arranged in a ring The outer side of the magnet block 31 is separated from it by a gap G. As the rotor 30 is driven by the power source 21 to rotate, the magnet block 31 on the periphery of the rotor 30 will be displaced relative to the coil body 43, thereby causing the coil body 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 10-20 degrees with the YY axis, the amount of induced current that would cancel each other out during the process of cutting the magnetic lines of force can be reduced. Moreover, because the approach area of the coil body 43 and the magnet block 31 is larger than the separation area, the magnetic group interference between the coil body 43 and the magnet block 31 is reduced, thereby achieving greater power generation efficiency.

[0092] Furthermore, the two conductors 431 of the coil winding 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 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, thus forming a larger loop of the coil winding 43; and because the magnetic field effect generated by the charged coil winding 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.

[0093] Figure 7FIG2 shows a structure 200 of a second embodiment of a wheel-ring type high-efficiency power generation device of the present invention, which is the same as the structure of the first embodiment and is indicated by the same figure number. The difference is that the present embodiment further 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 rim 53 of the electric vehicle, and one end thereof 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 its axial end face; 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 to the front wheel rim 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 On the inner side of the left frame cover 51, there are a central gear 21', several planetary gears 22, an annular internal gear 23 and a gear fixing plate 24. Among them, 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 shaft 10 by a ball bearing 12. In addition, the rotor 30 is provided with an axial hole 32, each end of which is pivoted on the outer edge of the central shaft 10 by a ball bearing 12. Several magnet blocks 31 are provided on the periphery of the rotor 30 and are connected to the central gear 21' by long screws 37 so as to rotate therewith. Because 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.

[0094] Furthermore, the stator 40 comprises an outer cover 41, a winding frame 42, and at least two sets of coil windings 43. The coil windings 43 are wound in a circular manner with multiple turns in the same direction. The stator 40 structure is formed by combining the coil windings 43, the winding frame 42, and the cover 41. The rotor 30 is placed in the through-hole 421 of the winding frame 42, and the gap G between the coil windings 43 and the magnet block 31 is maintained similar to the first embodiment described above, and therefore the details are not repeated. In this embodiment, as 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 is displaced relative to the coil windings 43. This causes the coil windings 43 to sense the change in the magnetic field and generate an induced current. The induced current is then guided outward from the wire hole 11 via the AC conductor 44.

[0095] The second embodiment of the present invention has a planetary gear set 20 in structure 200, and its structure is as follows: Figure 8As shown, the assembly is arranged on the inner side of the left frame cover 51, and comprises 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 rim 53, and the central gear 21' is pivoted 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 its rotation (see Figure 7 ); In the present invention, there are three planetary gears 22, which are arranged at an equal angle of 120° to each other; furthermore, the inner teeth 27 of the annular internal gear 23 are set to 96 teeth, while 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 acceleration 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 several magnet blocks 31 to increase the rotation speed by several times relative to the rotation of the front wheel rim 53, and then uses the coil winding body 43 to reduce the magnetic load in a synchronous and unidirectional circulating manner, and makes the induced current increase the voltage / current by 30~50%, thereby increasing the efficiency of its power generation device.

[0096] Figure 9FIG2 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 travel of the electric vehicle 300 and coordinating the braking; and when the electric vehicle 300 is moving, the front wheel 303 generates a large torque force, so 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, a power storage device 3 30, a motor driver 340, and an electric vehicle motor 350; in the application of this embodiment, the rectifier device 320 is installed on the front side of the vehicle body 301 of the electric vehicle 300 and is connected to the aforementioned AC conductor 44, so that the induced current generated by the coil winding 43 is transmitted to the rectifier device 320; since the power generation power changes with the speed of the front wheel 303, the rectifier device 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. The input end of the capacitor unit 331 is connected to the output end of the rectifier 320 via the charging input line 333. The capacitor unit 331 can be charged quickly and discharged slowly; the battery unit 332 receives the power discharged by the capacitor unit 331 and stores it. The fast power storage function of the power storage device 330 is applied in the present invention, so that the electric vehicle 300 can be charged quickly and discharged slowly. In the state, the charging operation is carried out uninterruptedly, so the energy 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 energy storage device 330 through the current output line 341 to convert the input constant voltage current into a variable voltage current, which is then transmitted through the 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.

[0097] In the present invention, the rotor 30 includes several magnet blocks 31 arranged at an angle θ of 10-20° to the axial direction, with adjacent magnetic poles having different orientations. The stator 40 includes at least two sets of coil windings 43, each with at least 12 turns of conductive wire 431 wound in the same direction, interlaced and stacked to form a single unit. The magnet blocks 31 are positioned at the outer edges of the coil windings 43, separated by a gap G. Rotation of the rotor 30 displaces the magnet blocks 31 relative to the coil windings 43, cutting magnetic flux lines. This cutting of magnetic flux lines reduces the amount of induced current that would otherwise cancel each other out. Because the approaching area of the coil windings 43 and the magnet blocks 31 is greater than the separating area, magnetic interference between the coil windings 43 and the magnet blocks 31 is reduced, resulting in greater power generation efficiency. Furthermore, the present invention also utilizes the transmission of the planetary gear set 20 to cause the rotor 30 equipped with the magnet block 31 to rotate at a speed 3.2 times that 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.

[0098] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.

The coil winding body is cyclically wound with a conductive wire in multiple turns in the same direction, and the number of consecutive turns is at least 12. The coil winding body forms a plurality of axially offset concave folds and convex folds, and the concave folds and convex folds of the coil winding body are then intertwined and stacked together to form a whole. The winding frame is made of insulating resin and is an annular structure with a through hole. The periphery forms an array of annular cavities, and the stacked coil winding body is enclosed 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 shaft to form the stator assembly structure. 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. Each group of coil windings forms an AC conductor and extends to the outside through the wire hole of the central shaft. In this way, the power source drives the rotor to rotate by transmitting power from the outside, and the magnet blocks on the periphery of the rotor will be displaced relative to the coil body, thereby inducing the coil body to sense the magnetic field change and generate an induced current, which is then transmitted to the outside through the AC wire.
