The present invention will be further described below in conjunction with drawings and embodiments.

A new type of power-feeding mechanism 3 is integrated into the wheel to obtain a power-feeding tire;

The power generation and energy feeding mechanism 3 includes a mover iron core 31, a three-phase winding 32, a fixed plate 33, a stator pendulum 34 and balls 35; the mover iron core 31 is evenly opened with tooth slots along the circumferential direction, and the three-phase windings 32 are embedded in the tooth slots. , and there are four axial light holes for fixing with the rim 2; the fixed plate 33 is an annular cylindrical structure, and there are four light holes along the axial direction. The apertures are the same size, and the four light holes are evenly distributed on the circumference of the fixed plate 33. The mover iron core 31 and the fixed plate 33 are fixed to the rim 2 through nuts 4 and bolts 5. During the operation of the vehicle, the mover iron core 31, fixed plate 33 The plate 33 rotates with the wheel; the fixed plate 33 has an annular T-shaped groove along the circumference for placing the stator pendulum 34; there are four raceways in the T-shaped groove, which are raceway A, raceway B, raceway C and The raceway D is full of balls 35 along the circumference, the main purpose of which is to reduce the friction between the stator pendulum 34 and the fixed plate 33 .

The stator pendulum 34 is welded by arc-shaped T-shaped steel 341 and arc-shaped permanent magnet 342. The arc-shaped permanent magnet 342 is radially magnetized, and N and S poles are arranged alternately; In the T-shaped slot of the fixed plate 33; the stator pendulum 34 does not rotate synchronously with the mover iron core 31 during the movement of the vehicle due to its own gravity.

The specific implementation process of the present invention will be further described below in conjunction with the accompanying drawings.

During the movement of the vehicle, the mover iron core 31, the fixed plate 33 and the rim 2 are fixedly connected by bolts 5, and the mover iron core 31 and the fixed plate 33 will rotate synchronously with the wheel; the arc-shaped T-shaped steel 341 of the stator pendulum 34 passes through the 35 is nested in the T-shaped groove of the fixed plate 33. Due to the effect of its own gravity, the rotational speed of the stator pendulum 34 is different from that of the fixed plate 33. At this time, it can be regarded as that the stator pendulum 34 is fixed, and the fixed plate 33 moves along the stator pendulum 34. rotation; since the fixed plate 33 and the mover iron core 31 rotate at the same speed, the stator pendulum 34 and the mover iron core 31 produce relative motion, and the three-phase winding 32 in the mover iron core 31 cuts the radial magnetization in the stator pendulum 34 The magnetic lines of force of the arc-shaped permanent magnet 342 induce a three-phase AC electromotive force in the three-phase winding 32 .

In new energy vehicles, the battery is the key. The battery needs to provide strong power for starting the engine and lighting, so it is necessary to ensure that the battery is fully charged. If the battery power is insufficient, the load performance of the engine can be ignored. At this time, the battery is used as the load of the engine, so that a part of the kinetic energy of the wheels is converted into electric energy through the power generation and feeding mechanism 3 to charge the battery. Mechanism 3 is working in the load state, and the back electromotive force is induced in the three-phase winding 32. Since the energy feed loop is closed, a part of the kinetic energy of the wheel is converted into electric energy. After the electric energy passes through the three-phase PWM rectifier and DC-DC boost conversion circuit, it is given to The composite energy storage system composed of batteries and supercapacitors on energy vehicles is charged, and the kinetic energy of the wheels is converted into electrical energy and stored for use when the car starts or accelerates; if the battery is fully charged, it can be disconnected during normal operation of the vehicle The energy feeding circuit, at this moment, the power generating and energy feeding mechanism 3 works in the no-load state. Although the three-phase electromotive force is induced in the three-phase winding 32, because the energy feeding circuit is disconnected, there is no current in the three-phase winding 32, and no kinetic energy is converted into The electric energy reduces the load on the engine; when the battery power is insufficient, the energy feed circuit can be reconnected, and the power generation feed mechanism 3 converts a part of the rotational kinetic energy of the wheels into electric energy to charge the battery again, and so on.

During the braking process of the vehicle, if the braking energy is not recovered, this part of energy will be converted into heat energy and dissipated in the air. The stator pendulum 34 and the mover core 31 induce alternating current in the three-phase winding 32 of the mover core 31 due to relative motion, and the alternating current is converted into direct current through a three-phase PWM rectifier and a DC-DC boost conversion circuit to charge the battery. The braking energy is converted into electrical energy and stored to achieve the purpose of recovering the braking energy.

For this type of energy-feeding tire, it is possible to control whether to recover the energy generated by the rotation of the wheel by turning on or off the energy-feeding circuit, which is easy to operate and flexible, and improves the life and work efficiency of the battery; at the same time, this power generation Due to the particularity of the mechanism, the energy feeding mechanism 3 itself can be transplanted to other rotary motion engineering machinery for energy recovery, and has strong portability, so it has strong practicability and applicability.
