DETAILED DESCRIPTION

[0023] like Figure 1 , Figure 2 As shown, the utility model provides a wheel hub of a new energy self-contained power generation device, comprising a wheel hub shell 1, two mirror image wheel hub outer edge rings 2 are fixedly installed on the outer wall of the wheel hub shell 1, and the wheel hub outer edge ring 2 is used to limit the tire of a car or an electric vehicle. A wheel hub outer cover 12 is arranged on the front side of the wheel hub shell 1, and a wheel hub inner cover 11 is arranged on the rear side of the wheel hub shell 1. A fixed bearing 111 is fixedly installed at the center of the wheel hub inner cover 11, and a rotating shaft 13 is fixedly installed on the inner ring of the fixed bearing 111. A stator bracket 131 is fixedly installed on the outer wall of the rotating shaft 13, and a plurality of stator permanent magnets 132 are fixedly installed in an annular array on both sides of the stator bracket 131. A bearing groove 121 is opened at the center of the wheel hub outer cover 12, and a bearing 122 is fixedly installed on the inner ring of the bearing groove 121, and the front end of the rotating shaft 13 is fixedly connected to the rear end of the bearing 122;

[0024] The actual width of the hub shell 1 can be changed according to the automobile or two-wheel or three-wheel electric vehicle hub used, and can be suitable for different new energy vehicles. When the hub shell 1 as a whole rotates under power, the left and right ends of the rotating shaft 13 are respectively connected to the fixed bearing 111 and the bearing 122, so that the stator bracket 131 and the several stator permanent magnets 132 on the left and right sides of the stator bracket 131 remain in the same position.

[0025] like Figure 3 As shown, mirror-image rotor cores 14 are arranged on both the front and rear sides of the inner cavity of the hub shell 1, and the inner and outer rings of the two rotor cores 14 are fixedly installed with rotor windings 141 in an annular array. The two rotor cores 14 are respectively located on the left and right sides of the stator bracket 131, and an output wire 133 is arranged at the center of the rear end of the rotating shaft 13. A protective ring 123 is fixedly installed at the eccentric position of the rear side of the hub cover 12, and a protective ring 15 is fixedly installed on the inner ring of the hub shell 1, and the outer rings of the two rotor cores 14 are fixedly connected to the inner ring of the protective ring 15;

[0026] The rotor core 14 and the rotor winding 141 on the front and rear sides of the inner ring of the protective ring 15 installed on the inner ring of the hub shell 1 can rotate with the hub shell 1, thereby rotating on the left and right sides of the stator bracket 131, prompting the rotor core 14 to cut the magnetic flux lines in the magnetic field formed by the stator permanent magnet 132. According to the principle of electromagnetic induction, this will generate an electromotive force, that is, voltage, in the coil, and use the output wire 133 to connect the external circuit to form an electric current, thereby generating electrical energy. At the same time, the protective ring 15 and the protective ring 123 are made of aluminum alloy inner core, and the outside is sprayed with graphene insulating heat dissipation paint, which improves the protection effect of the hub shell 1 on the internal rotor core 14 while avoiding electrical conduction and improving thermal conductivity.

[0027] like Figure 4 , Figure 5 As shown, a mounting ring 16 is fixedly installed on the rear side of the inner ring of the protective ring 15, and a plurality of bolt holes 161 are provided in a circular array on the mounting ring 16. A plurality of inner cover fixing bolts 112 are provided in a circular array through the front and rear of the wheel hub inner cover 11, and the plurality of inner cover fixing bolts 112 are respectively threadedly connected with the plurality of bolt holes 161.

The mounting plate 114 is provided with a plurality of mounting holes 115 that pass through the front and rear in a circular array. The mounting plate 114 can be fixed on the vehicle axle by using the mounting holes 115. A threaded hole 1331 is provided at the center of the front end of the output wire 133. An outer cover fixing bolt 124 is provided in the inner cavity of the bearing groove 121, and the rear end of the outer cover fixing bolt 124 passes through the center of the bearing 122 and is threadedly connected with the threaded hole 1331.

[0028] The installation of the hub inner cover 11 is completed by threading a plurality of inner cover fixing bolts 112 on the rear side of the hub inner cover 11 with a plurality of bolt holes 161 opened on the mounting ring 16. Otherwise, the hub inner cover 11 can be disassembled. The overall hub outer shell 1 can utilize the fixed mounting plate 114 on the rear side of the hub inner cover 11 to fix the bolts on the steering shaft, drive shaft, or wheel fixing shaft of the electric vehicle through the mounting holes 115. At the same time, the hub outer cover 12 can be threadedly connected with the threaded hole 1331 at the front end of the output wire 133 after passing through the outer cover fixing bolts 124 through the inner ring of the bearing 122 to complete the installation of the hub outer cover 12. At the same time, the bearing 122 on the inner ring of the bearing groove 121 does not affect the rotation of the hub outer cover 12 following the hub outer shell 1.

[0030] like Figure 1-5 As shown, when the hub shell 1 as a whole rotates under the driving force, the left and right ends of the rotating shaft 13 are respectively connected with the fixed bearing 111 and the bearing 122, so that the stator bracket 131 and the plurality of stator permanent magnets 132 on the left and right sides of the stator bracket 131 keep the same position, and the rotor core 14 and the rotor winding 141 on the front and rear sides of the inner ring of the protective ring 15 installed on the inner ring of the hub shell 1 can rotate with the hub shell 1, thereby rotating on the left and right sides of the stator bracket 131, so that the rotor core 14 cuts the magnetic flux lines in the magnetic field formed by the stator permanent magnet 132. According to the principle of electromagnetic induction, this will generate an electromotive force, that is, a voltage, in the coil, and the output wire 133 is used to connect the external circuit to form a current, thereby generating electrical energy. At the same time, the protective ring 15 and the protective ring 123 are both made of aluminum alloy inner core, and the outer surface is sprayed. The wheel hub shell 1 is made of graphene insulating heat dissipation coating, which improves the protection effect of the wheel hub shell 1 on the internal rotor core 14 while avoiding electrical conduction and improving thermal conductivity. At the same time, the installation of the wheel hub inner cover 11 can be completed by threading a plurality of inner cover fixing bolts 112 on the rear side of the wheel hub inner cover 11 with a plurality of bolt holes 161 opened on the mounting ring 16. Otherwise, the wheel hub inner cover 11 can be disassembled. The overall wheel hub shell 1 can utilize the fixed rear side mounting plate 114 of the wheel hub inner cover 11 to fix the bolts on the steering shaft or drive shaft of the vehicle through the mounting holes 115. At the same time, the wheel hub outer cover 12 can be threadedly connected to the threaded hole 1331 at the front end of the output wire 133 after passing through the inner ring of the bearing 122 through the outer cover fixing bolts 124 to complete the installation of the wheel hub outer cover 12. At the same time, the bearing 122 on the inner ring of the bearing groove 121 does not affect the rotation of the wheel hub outer cover 12 following the wheel hub shell 1.
