Known brake energy recovery devices are limited to several functions: for example, the device transmits the recovered kinetic energy to the electric motor that is originally a power output, and by rotating the coil inside the electric motor, a reverse current is generated by electromagnetic induction as electric energy recovery and storage. When an electric motor that is originally a power output is connected with the recovered kinetic energy to rotate, because the internal coil and iron core of the electric motor have a large moment of inertia when rotating, the reaction force affects the stability of the braking ability, and the internal coil is relatively large. It is difficult to control the magnitude of the induced electromotive force generated by electromagnetic induction at low speeds. A stable voltage can only be generated when the speed is higher than a specific speed range, which makes the kinetic energy recovery efficiency in the lower speed range poor. Therefore, it is necessary to use an additional speed change gear. It can be used as a kinetic energy recovery device after the generator is connected to increase its speed, but it also increases the overall weight and energy consumption; another brake energy recovery device transmits the recovered kinetic energy to the mechanical inertia flywheel through the clutch, and uses the drive inertia flywheel The rotational kinetic energy during rotation is stored as mechanical kinetic energy. This mechanical inertial flywheel kinetic energy storage method can only store mechanical kinetic energy in the high-speed region, and use the high-speed flywheel to drive slower vehicles to reduce fuel consumption. , so the recovery efficiency of the overall braking energy is limited, and the external inertial flywheel must have a certain mass so that it can store effective mechanical kinetic energy, which also results in Increased overall weight reduces power output efficiency and increases energy consumption.

Therefore, it is necessary to develop a braking energy recovery device that is light in weight, low in rotational inertia, can provide braking effect, can effectively recover kinetic energy in high and low speed ranges, and is sensitive and fast in response.

The electric charge flyback brake energy recovery device of the present invention includes a power input bearing connected to recovering kinetic energy; several planes are perpendicular to the axial direction of the power input bearing, and the rotating disks and fixed pieces are stacked in a very small distance. ; The rotating disk is composed of two insulating substrates and several pieces of positively charged conductive film and negatively charged conductive film that can be filled with positive and negative charges respectively. The center of the rotating disk plane is connected to the power input bearing. The conductive film with positive charge and the conductive film with negative charge are located on the edge of the connection between the center of the rotating disk plane and the power input bearing, and the positive charge charging electrode and the negative charge charging electrode are respectively connected to the charging wire on the power input bearing and conducted to Voltage regulator; the fixed piece is composed of two insulating substrates and several adjacent pieces of the first neutral conductive film and the second neutral conductive film that are paired with a transformer. The center of the fixed piece plane and the power input The axis of the bearing is aligned, but it is separated from the power input bearing and fixed on the device casing with a fixed seat. The output on the first neutral conductive film and the second neutral conductive film after two adjacent pieces of the fixed piece are connected and paired by a transformer The electrodes are connected to the primary coil of the transformer with output wires. When the recovered kinetic energy drives the rotating disk to rotate through the power input bearing, the rotating disk and the fixed plate will produce relative rotational motion on a plane perpendicular to the shaft center of the power input bearing. The conductive film with positive charge and the conductive film with negative charge are filled with positive and negative voltages to make the conductive film with positive and negative charges. Small plane distance through fixed piece The first neutral conductive film and the second neutral conductive film are above the plane of the two adjacent pieces that are paired through the transformer conduction. The neutral conductive film and the second neutral conductive film form positive and negative electric fields. According to Coulomb’s law, the formed positive and negative electric fields will make the conductive films on the plane of the fixed plate and the plane of the rotating disk overlap each other to generate attraction. The fixed plate forms a braking effect on the rotating disc, and the attractive force generated is proportional to the positive and negative voltages charged by the conductive film on the plane of the rotating disc, and the relative overlapping area between the plane of the rotating disc and the plane of the fixed plate. The plane distance of the conductive film is inversely proportional; when the voltage of the positive and negative charges of the positively charged conductive film on the plane of the rotating disk and the negatively charged conductive film is controlled by the voltage regulator, the transformer is used to conduct the conduction on the plane of the fixed plate. The size of the electric field formed by the overlapping area above the plane of the first neutral conductive film and the second neutral conductive film after pairing can adjust the size of the braking effect; when the power input bearing drives the rotating disc to continue to rotate, the plane of the rotating disc will The upper positively charged conductive film and the negatively charged conductive film produce a relative displacement in the plane direction to the original positions of the first neutral conductive film and the second neutral conductive film after the two adjacent pieces on the plane of the fixed plate are paired through a transformer. , so that the polarity of the positive and negative electric fields received by the first neutral conductive film and the second neutral conductive film after the two adjacent pieces of the fixed piece are paired by transformer conduction is reversed, and the polarity of the positive and negative electric fields received by the two adjacent pieces is originally distributed by the transformer conduction pairing The positive and negative charges on the surface of the first neutral conductive film and the second neutral conductive film will be redistributed and circulated between the primary side coils of the transformer; when the power input bearing continues to drive the rotating disc to rotate, the adjacent fixed plates will The polarity of the positive and negative electric fields received by the first neutral conductive film and the second neutral conductive film after the two pieces are paired by transformer conduction continues to change, causing positive and negative charges to continuously flow back and forth between the primary side coils of the transformer. The induced voltage generated by the secondary side is supplied to the load terminal and converted to Energy recovery; by increasing or reducing the number of stacked rotating discs and fixed pieces, or by controlling the voltage of positive and negative charges on the plane of the rotating disc with positively charged conductive film and negatively charged conductive film through a voltage regulator , you can change the maximum braking effect and energy recovery power of a single device.

The main parts inside the present invention are composed of conductive films and insulating substrates, which not only greatly reduce the mass, but also reduce the impact on the recovery of kinetic energy linkage during idling, and are more suitable for kinetic energy recovery in high and low speed ranges; the structure of the present invention is simplified and more It is easy to adjust the braking effect and the power of the recovered kinetic energy, providing faster braking control capability.
