Description

[0002] Chinese patent publication number CN 119483178A discloses a kinetic energy conversion Ampere force coupler, in which the conductive slip rings and conductive carbon brushes used for current transmission have certain shortcomings. If high-power power coupling and other speed output are to be achieved, it is often necessary to generate a large kinetic energy (recovery current) output. In this case, the Ampere force is proportional to the rotor diameter, so a larger diameter carbon brush is required for rotation. This also leads to a larger overall structure, an increase in occupied space, and a higher production cost, which affects normal use in existing scenarios. Summary of the Invention

[0024] The following will further describe in detail the specific embodiments of the present invention with reference to the drawings:

[0025] Such as Figures 1 to 5As shown in the figure, a device for magnetic and electric coupling transmission power recovery and electric energy reuse (restoration) includes a power coupling transmission permanent magnet cylinder 1, a power coupling transmission coil inner rotor 2, a power coupling output rotor shaft 3, a motor coil inner rotor 4, a motor permanent magnet cylinder 5, an intelligent electronic control circuit board 6, and a cross-over housing 7 sleeved outside the above components, with the load end of the power coupling output rotor shaft 3 as the front side. The above-mentioned power coupling transmission permanent magnet cylinder 1 is coaxially fixed with a central shaft 8 through a magnet cylinder fixing sleeve. The magnet cylinder fixing sleeve is fixedly connected to the power coupling transmission permanent magnet cylinder 1 by screws and fixedly connected to the central shaft 8 by key pins. The front end of the central shaft 8 is coaxially installed with a power coupling output rotor shaft 3, combined with Figure 7As shown, a coaxial embedded cavity is provided at the rear end of the power coupling output rotor shaft 3. The front end of the central shaft 8 is inserted into the embedded cavity and is rotatably connected through a first bearing 11. A first inner rotor fixing seat 31 and a second inner rotor fixing seat 32 are coaxially fixed on the power coupling output rotor shaft 3. They are integrally formed and are arranged opposite to each other, similar to the wheel set structure of a train. The inner rotor 2 of the power coupling transmission coil is coaxially fixed on the first inner rotor fixing seat 31 by screws, and the inner rotor 4 of the motor coil is coaxially fixed on the second inner rotor fixing seat 32 by screws, so that a certain set distance is left between the inner rotor 2 of the power coupling transmission coil and the inner rotor 4 of the motor coil. A smart electric control circuit board 6 is arranged at an interval on the front side of the inner rotor 4 of the motor coil. The smart electric control circuit board 6 is coaxially sleeved on the power coupling output rotor shaft 3 and is fixedly connected to it by screws, and an insulating flange sleeve 14 is clamped between the two. The inner rotor 2 of the power coupling transmission coil is connected to the input rectifying end of the smart electric control circuit board 6 through three phase lines (A-phase output line 15, B-phase output line 16, C-phase output line 17). The inverter output end of the smart electric control circuit board 6 is then connected to the inner rotor 4 of the motor coil through three phase lines. The inner rotor 2 of the power coupling transmission coil is placed inside the power coupling transmission permanent magnet cylinder 1 and is coaxially and rotatably arranged. A number of permanent magnets are fixedly arranged on the circumferential inner side wall of the power coupling transmission permanent magnet cylinder 1 at equal intervals along its circumference. The inner rotor 2 of the power coupling transmission coil includes a number of radial copper winding coils arranged along its circumference. A certain gap is left between the inner side of the permanent magnet and the outer diameter coil of the inner rotor 2 of the power coupling transmission coil, which can ensure that magnetic field cutting is completed while the two can rotate relative to each other. The outer side of the inner rotor 4 of the motor coil is coaxially sleeved with a motor permanent magnet cylinder 5. A number of permanent magnets are also arranged on the circumferential inner side wall of the motor permanent magnet cylinder 5, and a certain gap is left between its inner side and the inner rotor 4 of the motor coil. The cross-over housing 7 is in a fixed state and can be fixedly connected to the power input source by bolts. Its front end is open and is in the shape of a flange. The motor permanent magnet cylinder 5 is embedded and installed inside the front end head of the cross-over housing 7, and the fixation between the two is completed by bolts. The rear end of the cross-over housing 7 is fixedly installed with a rear end cover 13 by bolts. The central shaft 8 coaxially passes through the rear end cover 13 and is rotatably connected to it through a third bearing 13. A cross-over end cover 9 is fixedly installed on the front end side of the motor permanent magnet cylinder 5. A central hole is provided at its center. The front end of the power coupling output rotor shaft 3 passes through the central hole and extends forward, and is rotatably connected to the cross-over end cover 9 through a second bearing 12.

[0026] The specific working principle is as follows: Based on the B35 series motor as the power source input, the rear end of the above-mentioned central shaft 8 is coaxially and fixedly connected to the output main shaft of the motor, and the rear end of the above-mentioned cross-bridge housing 7 is fixedly installed on the body of the motor output end through bolts, so that the above-mentioned motor permanent magnet cylinder 5 remains fixed; the front end of the above-mentioned power coupling output rotor shaft 3 is connected to the load. When the motor is powered on, its output main shaft rotates, driving the central shaft 8 to rotate, and then driving the power coupling transmission permanent magnet cylinder 1 to rotate. At this time, the power coupling output rotor shaft 3 remains stationary under the action of its load, and the power coupling transmission coil inner rotor 2 fixed thereon also remains stationary, causing the copper winding coil on the power coupling transmission coil inner rotor 2 to cut the magnetic field generated by the power coupling transmission permanent magnet cylinder 1, generating an induced current in the coil, which is then connected and transmitted to the input rectification end of the above-mentioned intelligent electronic control circuit board 6 through the above-mentioned three-phase lines (A-phase output line 15, B-phase output line 16, C-phase output line 17) to achieve power output; there is current output on the power coupling transmission coil inner rotor 2, and then a magnetic torque is generated and acts on the power coupling output rotor shaft 3 to drive its rotation. By controlling the magnitude of the current output thereon, the magnitude of the coupling transmission torque can be achieved. At this time, there is a speed difference between the power coupling transmission coil inner rotor 2 and the power coupling transmission permanent magnet cylinder 1, and there is always magnetic force cutting. The magnitude of the coupling force follows Ampere's law.

[0027] After receiving the current input, the above-mentioned intelligent electronic control circuit board 6 performs a series of intelligent processes such as rectification and inversion according to the technical parameters of the electrical equipment, and then outputs the corresponding voltage and waveform, which are then output to the motor coil inner rotor 4 through the three-phase lines. The current flowing through the coil on the motor coil inner rotor 4 generates a magnetic force, which then interacts with the magnetic force on the above-mentioned motor permanent magnet cylinder 5 to drive the motor coil inner rotor 4 to rotate, and then accelerates to drive the power coupling output rotor shaft 3 to output rotational kinetic energy, converting the recovered electrical energy back into mechanical energy to achieve energy recovery and reuse, and improving the final rotational speed and torque of the motor output. When the load device needs to make an emergency stop, the above-mentioned intelligent electronic control circuit board 6 cuts off the current output, and no magnetic force is generated on the motor coil inner rotor 4. At this time, the transmission torque is almost zero and does not act on the power coupling output rotor shaft 3, enabling the emergency stop of the load device.

[0028] In a further optimized technical solution, the above-mentioned cross-bridge housing 8 is provided with a plurality of long strip-shaped heat dissipation holes 18 to prevent overheating during rotation and burning out the motor.

[0029] The device of the present invention is applicable to use as a rotational power source coupling transmission power in a variety of occasion fields, such as internal combustion engines, electric motors, high-speed rails, ships, fuel vehicles, electric vehicles, etc.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions, or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
