The speed reducing mechanism is composed of a support rod. The dual tube double acting hydraulic shock absorber comprises: the oil storage cylinder 11, the working cylinder 12, the T-shaped bolt 13, the piston 14 and the upper dust cover 15. A plurality of coils 7 in the electromagnetic energy capturing mechanism are wound outside the upper dust cover 6 in order; both ends of the aluminum bar 9 are provided with threads, and one end of the aluminum bar is fixed at the bottom of the lower dust cover 10 in a bolt connection mode; the ring magnet 8 is composed of two N, S magnet rings with different sizes, a N, S magnet alternative arrangement mode is adopted, small S ring magnets 813 are arranged in a large N ring magnet 811 side by side, the small S ring magnets and the large N ring magnet are sleeved on an aluminum bar 9 in a sleeved mode, an aluminum gasket 815 is arranged above the small S ring magnets and the small N ring magnet 815, the large S ring magnet 812 and the small N ring magnet 814 are sleeved on the aluminum bar 9 and are continuously arranged above the aluminum gasket 815, each layer of magnets with different polarities are spaced by the aluminum gasket 815, the process is repeated until the top of the aluminum bar 9 is screwed into a thread at the head of the aluminum bar 9, and the arranged ring magnet 8 and the aluminum gasket 815 are fixed; when the excitation of the automobile suspension is transmitted to the electromagnetic energy capturing mechanism, the vibration drives the lower dust cover 10 to move up and down, the coil 7 cuts the annular magnet 8 to generate a magnetic induction line, and therefore induced electromotive force is generated, and the purpose of collecting the vibration energy of the automobile suspension is achieved. In the double-cylinder double-acting hydraulic shock absorber, a piston 14 is fixed on an upper dust cover 15 by a nut; fixing the working cylinder 12 in the oil storage cylinder 11 by using a T-shaped bolt 20; the piston 14 is located inside the working cylinder 12.
As further described with reference to fig. 3, the pagoda spring 16 is disposed in a longitudinal slot bore in the skirt of the piston, with the bottom surface adjacent the piston head; the square gasket 17 is respectively and horizontally welded at the bottom of the pagoda spring 16 of the corresponding extension valve and the flow valve; the O-shaped ring is placed in a middle ring groove of the piston head; the anti-wear ring 19 is placed in the annular groove where the O-shaped ring is located and tightly presses the O-shaped ring; the antiwear ring 19 is closely attached to the inner wall of the working cylinder 12; the guide belts 18 are respectively placed in an upper ring groove and a lower ring groove of the piston head; the rubber gasket is adhered to the top of the piston in diameter; the nut secures the rubber washer and piston 14 to the piston rod on the upper dust cap 15.
To further describe the apparatus in conjunction with fig. 4, the working cylinder 12 is placed at the bottom of the reservoir cylinder 11 with the bottom facing downward; the working cylinder barrel 12 and the oil storage cylinder barrel 12 are concentrically and coaxially arranged; the trapezoidal gasket 24 is placed between the working cylinder and the oil storage cylinder; the rubber gasket 23 is placed between the working cylinder 12 and the trapezoidal gasket 24, and is closely attached to them; the T-shaped bolt 20 penetrates through the working cylinder 12 and the trapezoidal gasket 24 to be fixed on the oil storage cylinder 11 in a bolt connection mode; the top of the spiral spring 21 is attached to the top of the T-bolt 20, and the bottom is attached to the inner wall of the bottom of the working cylinder 12.
The working principle is as follows: when the automobile runs to a bumpy road section, the automobile suspension generates vibration, the vibration is transmitted to the electromagnetic energy capturing mechanism, the annular magnet 8 which generates magnetic induction lines in the electromagnetic energy capturing mechanism moves up and down relative to the coil 7, and the coil 7 cuts the magnetic induction lines to generate induced electromotive force. The vibration is continuously transmitted to the buffer through the elastic base, the distance from the electromagnetic energy capturing structure to the buffer is twice as long as the distance from the double-cylinder double-acting hydraulic shock absorber to the buffer, so that the vibration damping device has a good vibration damping effect, and when the speed is transmitted to the double-cylinder double-acting hydraulic shock absorber, the shock absorber can move up and down; when the piston 14 moves downwards relative to the working cylinder 12, the pressure intensity of the hydraulic oil in the working cylinder 12 at the lower part of the piston 14 is increased, the hydraulic oil can extrude the flow valve 27 on the piston, and the spring expanding gasket 17 is expanded because the pressure intensity of the hydraulic oil is larger than the elastic force of the pagoda spring 16, so that the hydraulic oil flows into the working cylinder 12 with small pressure intensity above the piston, and the pressure intensity of the upper part and the lower part of the piston 14 is balanced; however, because of the existence of the piston rod, the hydraulic oil still cannot flow above the piston enough to balance the pressure below, so a part of the hydraulic oil in the working cylinder 12 also presses the compression valve at the bottom to open the gasket on the compression valve, so that the hydraulic oil flows into the oil storage cylinder 11 to balance the pressure. When the piston 14 moves upward relative to the working cylinder 12, the pressure of the working cylinder above the piston 14 increases and is greater than that of the working cylinder 12 below, at this time, the hydraulic oil above the working cylinder 12 can extrude the rubber gasket below the extension valve 26 to open the gasket, the hydraulic oil flows into the working cylinder 12 below to balance a part of the pressure, but because the piston rod exists above and is not enough to balance the pressure below, the hydraulic oil in the oil storage cylinder 11 enters the working cylinder 12 by extruding the gasket 21 above the compensation valve, and the pressure in the working cylinder 12 is balanced. The device recovers the vibration when the vibration is attenuated, breaks through the traditional method of only damping or harvesting energy, improves the utilization rate of vibration energy and reduces the waste of energy.
The foregoing description is only a proper embodiment of the present invention, and it should be noted that any person skilled in the art can make several changes or modifications without departing from the principle of the present invention, and these changes or modifications should also be construed as the protection scope of the present invention.
