[0016] The above and / or additional aspects and advantages of the present invention will become apparent and easily understood from the description of the embodiments in conjunction with the following drawings, in which:

[0017] Figure 1 It is a principle block diagram of an inertial energy storage structure device. DETAILED DESCRIPTION

[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0019] In the description of the present utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection of two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0020] like Figure 1 As shown, the utility model provides an inertial energy storage structure device, which includes an inertial flywheel 1, a permanent magnet generator 2, an AC / DC voltage stabilizing module 4 and an energy storage battery 5.

[0021] The input shaft of the inertia flywheel 1 is connected to a rotating shaft (not shown), which can be a rotating shaft driven by a generator or an engine, or directly an output shaft of the engine, or a rotating shaft driven by other equipment or structures. When the rotating shaft rotates, the inertia flywheel 1 is driven to rotate.

[0022] The output shaft of the inertial flywheel 1 is connected to the input shaft of the permanent magnet generator 2. The inertial flywheel 1 rotates, which drives the permanent magnet generator 2 to rotate and generate electric energy. The voltage output end of the permanent magnet generator 2 is connected to the AC / DC voltage stabilizing module 4. The AC / DC voltage stabilizing module 4 stabilizes the voltage output by the permanent magnet generator 2 and converts it into direct current, which is then transmitted to the energy storage battery 5 for storage.

[0023] The inertial flywheel 1 is driven to rotate by the rotating shaft, and the permanent magnet generator 2 is linked to rotate to generate electrical energy. No rotating wave box is arranged between the output shaft of the inertial flywheel 1 and the input shaft of the permanent magnet generator 2, which reduces the loss of mechanical energy and improves the conversion rate of mechanical energy into electrical energy.

[0024] The AC / DC voltage stabilizing module 4 includes a bridge rectifier, a three-terminal voltage stabilizing chip, a first capacitor C1, a third capacitor C3, an NPN transistor and a variable potentiometer R1. In this embodiment, the bridge rectifier is preferably but not limited to a DB bridge rectifier, and the three-terminal voltage stabilizing chip is preferably but not limited to an LM three-terminal voltage stabilizing chip.

[0025] The AC voltage output end of the permanent magnet generator 2 is connected to the AC input end of the DB bridge rectifier, the voltage output end of the DB bridge rectifier is connected to one end of the first capacitor C1 and the input end of the LM three-terminal voltage regulator chip, the other end of the first capacitor C1 is grounded, the ground end of the LM three-terminal voltage regulator chip is connected to one end of the variable potentiometer R1 coil, the sliding end of the variable potentiometer R1 is grounded, the other end of the variable potentiometer R1 coil is connected to the base of the NPN transistor, the NPN transistor is used for current amplification, the emitter of the NPN transistor is grounded, and its collector is connected to the second resistor R2 and then connected to the output end of the LM three-terminal voltage regulator chip, the collector of the NPN transistor is also connected to the energy storage capacitor C2, the other end of the energy storage capacitor C2 is grounded, and a third capacitor C3 is also connected between the output end of the LM three-terminal voltage regulator chip and the ground, the output end of the LM three-terminal voltage regulator chip is connected to the positive electrode of the energy storage battery 5, and the negative electrode of the energy storage battery 5 is grounded.

[0026] When the permanent magnet generator 2 outputs an alternating voltage, it is rectified by the DB bridge rectifier and converted into a DC voltage, then filtered by the first capacitor C1, and fed back to the third capacitor C3 by the LM three-terminal voltage regulator chip for power storage and voltage stabilization, and the variable potentiometer R1 is adjusted to adjust the input voltage to achieve a regulated output.

[0027] like Figure 1 As shown, in a preferred solution of this embodiment, a BLDC brushless motor and a DCAC controller 3 are also included. The BLDC brushless motor has a built-in planetary transmission structure, and in this preferred solution, its transmission ratio is 1:4.5.

[0028] In this preferred embodiment, the BLDC brushless motor is built into the housing of the inertial flywheel 1, and the output shaft of the BLDC brushless motor is connected to the input shaft of the inertial flywheel 1. The energy storage battery 5 is connected to the DCAC controller 3, and the DCAC controller 3 is connected to the BLDC brushless motor control. The DCAC controller 3 converts the DC power provided by the energy storage battery 5 into a three-phase AC power supply for the operation of the BLDC brushless motor. That is, the inertial flywheel 1 is not only driven to rotate by the rotating shaft, but the DCAC controller 3 also controls the operation of the BLDC brushless motor with a trace amount of energy, drives the inertial flywheel 1 to rotate, and links the permanent magnet generator 2 to rotate to generate electrical energy. That is, when the rotating shaft stops driving the inertial flywheel 1 to rotate, the inertial flywheel 1 can still maintain low-speed rotation with the trace energy provided by the DCAC controller 3.

[0029] A further optimization of this preferred scheme is that when the inertial flywheel 1 is driven by the rotating shaft to rotate and the rotation energy has a uniform linear velocity, the DCAC controller 3 controls the operation of the BLDC brushless motor with a trace amount of energy, drives the inertial flywheel 1 to rotate, and links the permanent magnet generator 2 to rotate at a uniform speed to generate electrical energy.

[0030] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0031] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
