Description

Technical Field

[0001] The utility model relates to the technical field of wheel axle power generation, in particular to a charging device for a rotating permanent magnet generator of an automobile wheel axle head. Background Art

[0002] With the gradual popularization of electric vehicles, the demand for electric energy is increasing. At present, a generator is often installed on the wheels of the car to convert the mechanical energy generated by the rotation of the wheel into electrical energy for storage and use by the electric car. The existing wheel generator mainly generates a magnetic field through the stator, and the rotor is cut by the magnetic lines of force in the rotating magnetic field to generate current. However, in the actual power generation process, the rotor rotates on the stator, so that the rotor and the stator have more direct contact, which is easy to increase energy loss, resulting in limited electric energy, unstable power output, reduced efficiency and performance of the generator, and poor practicality. Utility Model Content

[0005] A vehicle wheel axle head rotating permanent magnet generator charging device comprises a wheel axle head, a brake disc detachably arranged on the wheel axle head, and a brake cylinder mounted on the brake disc, a power generation mechanism for generating electricity by following the rotation of the wheel axle head is arranged on one side of the brake disc, the power generation mechanism comprises a generator housing arranged on the brake disc, and the generator housing is fixedly mounted on the fixing bolts of the brake cylinder, and a rotor is arranged on one side of the brake disc for rotating to generate a magnetic field and cutting magnetic lines of force to generate electrical energy during rotation, and a stator for generating a rotating alternating magnetic field is arranged on the inner side of the generator housing.

[0006] Furthermore, the rotor includes a hollow sleeve mounted on the wheel axle head by bolts, the hollow sleeve is rotatably connected to the generator housing by a bearing, and a ring sheet is fixedly arranged on the outside of the hollow sleeve.

[0008] Furthermore, the stator includes a plurality of magnet sheets 2 arranged in a fan-shaped array on the inner side of the generator housing, and the magnet sheets 2 are fixedly bonded to the inner wall of the generator housing by epoxy resin.

[0011] By means of the above technical solution, the utility model provides a vehicle wheel axle head rotating permanent magnet generator charging device, which has at least the following beneficial effects compared with the prior art:

[0012] 1. The utility model converts the mechanical energy of the wheel axle head rotation into electrical energy by setting a power generation mechanism, and stores the electrical energy for use by the car. When generating electricity, the wheel axle head drives the rotor to rotate, generates a magnetic field and cuts the magnetic lines of force generated by the stator during the rotation process to form an electric current. In addition, there is a certain gap between the magnet sheet of the rotor and the hollow copper coil of the stator, which can effectively avoid direct contact between the stator and the rotor, reduce energy loss, improve efficiency and energy utilization while stabilizing the power output, and enhance the practicality of the charging device.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Since the existing rotor 43 rotates directly on the stator 44, and the copper wire winding of the stator 44 is embedded in its iron core, the actual size of the stator 44 is also large, and the rotor 43 is prone to large energy loss when rotating. In order to reduce energy loss and improve efficiency and energy utilization while stabilizing the power output, refer to Figure 1-Figure 6 , provides a permanent magnet generator charging device for rotating axle head of an automobile, comprising a wheel axle head 1, a brake disc 2 detachably arranged on the wheel axle head 1, and a brake cylinder 3 installed on the brake disc 2. The wheel axle head 1, the brake disc 2 and the brake cylinder 3 are all prior arts and are not described in detail in this application. The brake cylinder 3 is in a vertical state with the support axle head sleeve disc on the brake disc 2 to ensure the safe and stable operation of the generator. A power generation mechanism 4 for generating electricity by following the rotation of the wheel axle head 1 is arranged on one side of the brake disc 2.

[0027] In order to effectively avoid direct contact between the stator 44 and the rotor 43 and reduce energy loss, it is achieved through a power generation mechanism 4, including a generator housing 41 arranged on the brake disc 2, and the generator housing 41 is fixedly mounted on the fixing bolts of the brake cylinder 3, and the generator housing 41 can also be fixedly mounted on the upper and lower brackets of the wheel axle head 1 by bolts. The generator housing 41 is made of aluminum alloy material, and a rotor 43 is arranged on one side of the brake disc 2 for rotating to generate a magnetic field and cutting magnetic lines of force to generate electrical energy during rotation. A stator 44 for generating a rotating alternating magnetic field is arranged on the inner side of the generator housing 41, and a cover plate 42 for protecting the stator 44 and the rotor 43 is fixedly arranged on one side of the generator housing 41 by bolts, thereby extending the service life of the stator 44 and the rotor 43, and making disassembly more convenient when maintenance is required.

[0028] In order to ensure stable rotation to generate magnetic field and cut magnetic lines of force to generate electrical energy during rotation, refer to Figure 2 and Figure 5 Specifically, the rotor 43 includes a hollow sleeve 431 installed on the wheel axle head 1 by bolts, and the hollow sleeve 431 is rotatably connected to the generator housing 41 by a bearing, and a ring piece 432 is fixedly arranged on the outside of the hollow sleeve 431, and the hollow sleeve 431 and the ring piece 432 are both made of stainless steel material, and fourteen magnet pieces 433 distributed in a circular array are arranged on one side of the ring piece 432, the magnet piece 433 is made of rare earth permanent magnets, and the magnet piece 433 and the ring piece 432 are fixed by epoxy resin.

[0029] In order to generate a more stable rotating alternating magnetic field, refer to Figure 2 and Figure 4 Specifically, the stator 44 includes twelve magnet sheets 441 distributed in a fan-shaped array arranged on the inner side of the generator housing 41. The magnet sheet 441 is made of rare earth permanent magnets, and the magnet sheet 441 is fixedly bonded to the inner wall of the generator housing 41 by epoxy resin. A hollow copper coil 442 is arranged on one side of the magnet sheet 441, and the hollow copper coil 442 is fixed to the magnet sheet 441 by epoxy resin. Under the action of the magnetic field when the rotor 43 rotates, the hollow copper coil 442 in the stator 44 will generate an induced current, and a power connector is arranged on the generator housing 41 to store the generated electric energy in an external battery.

[0030] The second magnet piece 441 on the inner side of the generator housing 41 has opposite magnetic poles to the first magnet piece 433 corresponding to one side of the ring piece 432. When the rotor 43 rotates, the cut magnetic lines of force are frequently converted, thereby generating an induced current.

[0031] In actual use of the utility model, when the car is running, the wheel axle head 1 rotates, the wheel axle head 1 drives the hollow sleeve 431 thereon to rotate, the hollow sleeve 431 drives the ring piece 432 on its outer side to rotate, the ring piece 432 drives the fourteen magnet pieces 1 433 thereon to rotate, when the magnet piece 1 433 rotates, under the action of the magnetic field, the twelve magnet pieces 2 441 are cooperated at the same time, so that the hollow copper coil 442 generates a stable induced current, and the electric energy is stored in the battery for use in the electric vehicle.
