Description

[Technical field]

[0001] The present invention relates to a power output flywheel device, and more particularly to a power output device that reduces energy consumption by using the moment of inertia due to the rotation of the flywheel to reduce the initial driving force for starting a power output unit to which the flywheel is connected. [Background technology]

[0002] Some conventional power output devices include a power output unit and an electric motor. The power output unit is, for example, a hydraulic pump or a vacuum pump, and is connected to the electric motor via a power bearing shaft. The electric motor uses electricity to rotate the power bearing shaft, thereby starting the power output unit and outputting power.

[0003] However, when starting the power bearing shaft of a power output unit with an electric motor, the power bearing shaft is rotated by the electric motor from a stationary state, and therefore the static friction of the power bearing shaft must be overcome in order to obtain the rotational force required for the power bearing shaft, and therefore the power bearing shaft cannot be rotated unless a large amount of power is consumed to drive the electric motor. Therefore, conventional power output devices are not environmentally friendly because they require a large amount of power consumption when starting the power output unit, and there is room for improvement. Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention provides a power output flywheel device which solves the problem in the conventional power output devices that a large amount of electric energy needs to be consumed when starting up the power output unit, which is not environmentally friendly. [Means for solving the problem]

[0005] In order to achieve the above object, the technical means adopted in the present invention is to provide the following power output flywheel device: a power supply control module to which a power input source is connected; an electric motor electrically connected to the power supply control module and controlled and powered by the power supply control module; a one-way transmission assembly including a motor connection shaft connected to the electric motor and a one-way bearing provided on the motor connection shaft; a flywheel having an attachment part connected to the one-way bearing and an inertia output part formed on both sides thereof, the flywheel rotating in an axial direction relative to the electric motor and interlocking with the electric motor via the one-way transmission assembly; a power output unit connected to the inertial output portion of the flywheel and operatively linked to the flywheel. Effect of the Invention

[0006] In the power output flywheel device of the present invention, the one-way transmission assembly and the flywheel are connected between the electric motor and the power output unit, so that power consumption can be reduced when the power output unit is started. Specifically, the electric motor is controlled and powered by the power supply control module, and rotates the flywheel in conjunction with the electric motor via the one-way transmission assembly, thereby generating a moment of inertia in the flywheel and storing energy. When starting the power output unit, the electric motor can rotate the power output unit in conjunction with the power output unit via the flywheel with less power due to the energy previously stored in the flywheel. Furthermore, power consumption can be reduced when starting the power output unit, which has an effect of being environmentally friendly.

[0007] In addition, when the rotational speed of the electric motor decreases and the rotational speed of the motor connecting shaft becomes slower than the rotational speed of the flywheel, the motor connecting shaft stops linking with the flywheel via the one-way bearing, so that the rotation of the flywheel and the storage of energy are not affected, and the flywheel can still store the energy supplied by the power output unit, thereby contributing to the operation of the power output unit.

[0009] As shown in FIGS. 1 and 2, a preferred embodiment of a power output flywheel apparatus of the present invention includes a power supply control module 10 connected to a power input source, an electric motor 20, a one-way transmission assembly 30, a flywheel 40, and a power output unit 50.

[0010] As shown in FIGS. 1 and 5, the electric motor 20 is electrically connected to the power supply control module 10 and is controlled and powered by the power supply control module 10.

[0011] As shown in FIGS. 2, 3, 5 and 6, the one-way transmission assembly 30 includes a motor connection shaft 31 connected to the electric motor 20 and a one-way bearing 32 provided on the motor connection shaft 31.

[0012] As shown in Figures 2 to 6, the flywheel 40 is disk-shaped and has an attachment part 41 connected to the one-way bearing 32 and an inertia output part 42 formed on both sides. The flywheel 40 rotates in the axial direction relative to the electric motor 20 and is linked to the electric motor 20 via the one-way transmission assembly 30.

[0013] As shown in FIGS. 2, 3, 5 and 6, the power output unit 50 is connected to the inertia output portion 42 of the flywheel 40 and is linked to the flywheel 40.

[0014] In the power output flywheel device of the present invention, the one-way transmission assembly 30 and the flywheel 40 are connected between the electric motor 20 and the power output unit 50, so that the power consumption can be reduced when the power output unit 50 is started. To be more specific, the electric motor 20 is controlled and powered by the power supply control module 10, and the flywheel 40 is rotated in conjunction with the electric motor 20 via the one-way transmission assembly 30, thereby generating a moment of inertia in the flywheel 40 and storing energy. In other words, if static friction is greater than kinetic friction, a large initial driving force is required to start the power output unit 50 from a non-rotating state. However, in the present invention, since the flywheel 40 continues to rotate, the initial driving force can be reduced by the moment of inertia of the flywheel 40, and the starting current can also be reduced. As a result, when the power output unit 50 is started, the electric motor 20 can rotate the power output unit 50 in conjunction with the flywheel 40 with less power due to the energy previously stored in the flywheel 40, so that the power consumption when starting the power output unit can be effectively reduced, which is environmentally friendly.

[0015] Furthermore, with this configuration, a moment of inertia can be generated in the flywheel 40 to store energy, so that while the power output unit 50 continues to operate, the continuous power output required for the electric motor 20 to operate in conjunction with the power output unit 50 can be saved, thereby achieving a sustained power saving effect, and the torque output of the electric motor 20 can be adjusted using the moment of inertia of the flywheel 40.

[0016] As shown in Figs. 4 to 7, a mounting portion 41 of a flywheel 40 is formed with an accommodation groove 43 in which a one-way bearing 32 is accommodated. The one-way bearing 32 has an inner ring 321 and an outer ring 322 that rotate relatively. The motor connecting shaft 31 is connected to the inner ring 321 of the one-way bearing 32, and the outer ring 322 of the one-way bearing 32 is connected to the flywheel 40. As a result, the motor connecting shaft 31, which rotates along the driving direction D, rotates the flywheel 40 in an interlocking manner via the one-way bearing 32. On the other hand, when the rotation speed of the electric motor 20 decreases and the rotation speed of the motor connecting shaft 31 becomes smaller than the rotation speed of the flywheel 40, the motor connecting shaft 31 rotates in the direction opposite to the driving direction D relative to the flywheel 40, so that the flywheel 40 cannot be interlocked via the one-way bearing 32. As a result, the rotation and energy storage of the flywheel 40 are not affected, and the flywheel 40 can still store energy provided by the power output unit 50, thereby serving the operation of the power output unit 50. It should be noted that the one-way bearing 32 shown in the figure is merely for the purpose of explaining the method of operation, and the one-way bearing 32 is not limited to the form shown in the figure, and other forms of one-way bearings can also be used.

[0017] 1 to 3, the power output flywheel device includes a cover 60 provided on the electric motor 20, the one-way transmission assembly 30 and the flywheel 40 are located inside the cover 60, and the power output unit 50 is provided on the side of the cover 60 farther from the electric motor 20 and extends into the cover 60 to be connected to the flywheel 40. According to this configuration, the one-way transmission assembly 30 and the flywheel 40 are protected by the cover 60, so that it is possible to prevent foreign objects from interfering with the operation of the power output flywheel device.

[0018] It is preferable that the power supply control module 10 is provided in the electric motor 20, which allows the power output flywheel device to be made compact.

[0019] The power input source is preferably a solar energy power generation module, so that the power supply control module 10 is powered by solar energy generation, and the use of a power output flywheel device is more environmentally friendly. In addition, since the power generated by solar energy is direct current, there is no need to install a separate converter to convert alternating current to direct current and supply it to the power supply control module 10, so not only costs but also installation space can be saved.

[0020] As shown in Figures 1 and 5, the power output flywheel device is provided on the electric motor 20, electrically connected to the power supply control module 10, and includes an electric motor cooling module 70 controlled by the power supply control module 10 to cool the electric motor 20, thereby reducing the thermal loss of the electric motor 20.

[0021] Furthermore, the hydraulic pump of the conventional garbage collection vehicle is driven by a motor, but when the motor is connected to the battery pack of the garbage recycling vehicle to link the hydraulic pump, the starting current for starting the hydraulic pump is large, so power consumption is large, and a large space is required to connect the large battery pack, and the torque for starting the hydraulic pump is also large, so the motor itself is large and quite heavy. Also, when the motor is connected to the engine transmission of the garbage collection vehicle via a transmission shaft and a power distribution device, and the motor is driven by the energy generated during the engine idling to operate the pump, the overall structure consisting of the motor, transmission shaft, and power distribution device is heavy and complex, so there is a large loss during energy transmission and a large space is required, which increases the space required for the entire vehicle. On the other hand, when the power output flywheel device of the present invention is applied to a garbage collection truck, the hydraulic pump of the garbage collection truck corresponds to the power output unit 50, and the power supply control module 10 is electrically connected to a battery to supply power, so that the electric motor 20 of the power output flywheel device can operate the hydraulic pump via the flywheel 40 with only a small amount of power consumption. In addition, the overall weight of the present invention is light and the space occupied by the present invention is small, so that the overall vehicle can be made more compact.

[0022] The power output flywheel device can also be applied to a fixed-position trash compactor, where the power output unit 50 is a hydraulic pump to compact the trash, and the fixed-position trash compactor is suitable for installing a solar power generation module, making trash collection more environmentally friendly.

[0023] The power output unit 50 is preferably a hydraulic pump, but may also be a vacuum pump, a water pump, or a large generator, etc., and the type of the power output unit 50 can be selected according to the needs of the user. For example, when the present invention is applied to a garbage truck or an elevator, the power output unit 50 may be a hydraulic pump; when the present invention is applied to a water fertilizer truck, a mud suction truck, or aquaculture vehicle, the power output unit 50 may be a vacuum pump; when the present invention is applied to a sprinkler, a water truck, or aquaculture, the power output unit 50 may be a water pump; when the present invention is applied to an emergency energy storage vehicle, a cave fire truck, or a power output balancing device, the power output unit 50 may be a large generator.

[0024] As described above, in the power output flywheel device of the present invention, the one-way transmission assembly 30 and the flywheel 40 are connected between the electric motor 20 and the power output unit 50, and the electric motor 20 rotates the flywheel 40 in conjunction with the one-way bearing 32 of the one-way transmission assembly 30, thereby generating a moment of inertia in the flywheel 40 and storing energy. As a result, when starting the power output unit 50, the starting current can be reduced by the energy previously stored in the flywheel 40, and therefore the power consumption when starting the power output unit 50 can be reduced, which is very energy-saving and environmentally friendly.
