Description

Technical Field

[0001] The invention belongs to the technical field of automobile suspension, and in particular relates to a suspension cylinder type energy recovery system and method. Background Art

[0002] At present, the relevant suspension system uses oily medium in a fixed compression state. This is also an important reason why different models have different driving experiences. If the suspension damping setting is large, the vehicle suspension is relatively hard and the chassis has strong support. However, the comfort of the vehicle will be greatly reduced when facing bumpy roads. If the suspension damping setting is small, the vehicle suspension is soft. Although it can filter out the small bumps on the road, the suspension's shock absorption capacity is limited when facing a larger impact, and the vehicle body will be unstable.

[0003] Studies have shown that the energy consumed by vehicle vibration is far greater than the energy consumed by vehicle braking. If the vibration energy can be effectively recovered, the vehicle's range can be increased by 20% to 30%. However, current suspension structures usually do not recover this energy, resulting in energy waste. Summary of the invention

[0015] A suspension cylinder type energy recovery method comprises the following steps:

[0016] Step 1: First, push the connecting blocks on both sides to drive the two movable columns to move and approach each other, and drive the two semicircular rings to approach each other through the fixed block and the mounting block until the piston rod is clamped, and at the same time, drive the slider to move along the crossbar through the first rotating rod to stretch the first spring, and at the same time, the fixed block moves to drive the two external sleeves to move and move away from each other, and drive the inner rings to move away from each other, and then tighten the nuts on both sides to fix the position of the connecting blocks, so that the two semicircular rings and the two inner rings limit the piston rod, and then the piston rod can move vertically;

[0017] Step 2: Then add the oil medium into the lower cylinder through the oil inlet. When the oil medium flows between the lower cylinder and the lower piston plate, a damping effect is generated. When the suspension is subjected to vertical vibration, the lower piston plate moves vertically, changing the volume between the top of the upper piston plate and the upper cylinder. When the vibration is transmitted to the lower piston plate through the piston rod, the volume of the lower fixed plate and the lower piston plate changes during the movement of the lower piston plate. The oil medium flows in the damping hole to generate damping. The upper cylinder adds gas medium into its interior from the air inlet.

[0018] Step 3: Finally, the change in air pressure inside the upper cylinder changes the volume of the left side of the movable plate inside the box through the vent pipe, driving the movable plate to move horizontally, and at the same time driving the vertical block to move horizontally. Since there are magnetic flux lines between the two magnetic plates, the vertical block moves between the two magnetic plates and cuts the magnetic flux lines, thereby generating current. The current is transmitted to the battery from the conductive rod and the wires at both ends of the rod, and the vibration energy can be recovered.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The present invention, through the cooperation between the vent pipe and the box body, and the guide groove and the guide block, when the volume inside the upper cylinder changes, the volume of the left side of the movable plate inside the box body can be changed through the vent pipe, and the movable plate can be moved laterally. At the same time, two magnetic plates are arranged inside the box body, so that magnetic flux lines can be generated between the two magnetic plates. When the movable plate moves, it can drive the vertical block and the conductive rod to move. Then, when the vertical block moves between the two magnetic plates, it can cut the magnetic flux lines, thereby generating current, which is transmitted to the inside of the battery through the conductive rod and the wires at both ends thereof, so as to facilitate the absorption of vibration energy;

[0021] (2) The invention achieves cooperation between the top ring, the lower support tube and the lower support rod. When the piston rod moves, the second spring will expand and contract. At the same time, the force can be absorbed by the elasticity of the second spring. When the road surface is bumpy and the vibration is large, the vibration of the road surface is absorbed by the lower cylinder body, thereby improving the driving rigidity, enhancing the handling performance and safety. Moreover, through the cooperation between the vertical rod and the fixed frame, and the movable frame and the upper support tube, the third spring can expand and contract when the piston rod moves. At the same time, the force can be absorbed by the elasticity of the third spring. Therefore, when the road surface is relatively smooth, most of the vibration generated is dissipated by the upper cylinder body, thereby improving the driving comfort.

[0022] (3) The invention enables the two semicircular rings to move and approach each other through the cooperation between the connecting block, the movable column and the fixed block, and then clamp the piston rod. At the same time, the first spring is stretched through the cooperation between the first rotating rod and the slider. At the same time, the connecting block can be fixed through the cooperation between the nut and the screw rod. The two inner rings can be moved through the cooperation between the second rotating rod and the external sleeve. Then, the piston rod can be limited by the two semicircular rings and the two inner rings, thereby ensuring that the piston rod can move vertically and increasing the stability of the device.

[0036] Embodiment 2, on the basis of embodiment 1, the lower buffer mechanism 4 includes a top ring 401, a second spring 402, a lower support rod 403 and a lower support tube 404, the bottom of the top ring 401 is fixedly connected to the top of the lower piston plate 15, and the top ring 401 is located inside the lower cylinder body 1, the lower support tubes 404 are equidistantly distributed on the top of the top ring 401, the top ring 401 is movably sleeved with the lower support rod 403, the bottom end of the lower support rod 403 extends to the inside of the lower support tube 404, the top end of the lower support rod 403 is fixedly connected to the bottom of the lower fixed plate 14, the second spring 402 is movably sleeved with the lower support rod 403, the bottom end of the second spring 402 is fixedly connected to the top of the lower support tube 404, the top end of the second spring 402 is fixedly connected to the bottom of the lower fixed plate 14, and the upper buffer mechanism The structure 5 includes a vertical rod 501 fixedly connected to the top of the upper piston plate 16, the vertical rod 501 is located inside the upper cylinder body 12, a movable frame 505 is fixedly installed on the top of the vertical rod 501, a fixed frame 506 is movably installed on the outer side of the vertical rod 501, and the fixed frame 506 is located below the movable frame 505, a third spring 504 is fixedly connected between the movable frame 505 and the fixed frame 506, the third spring 504 is movably sleeved with the vertical rod 501, an upper support cylinder 503 is fixedly connected to the bottom of the inner cavity of the upper cylinder body 12 at an equal angle, an upper support rod 502 is movably sleeved inside the upper support cylinder 503, the bottom end of the upper support rod 502 is fixedly connected to the top of the upper piston plate 16, the fixed frame 506 is fixedly connected to the upper support cylinder 503, and the movable frame 505 is movably connected to the upper support cylinder 503;

[0037] Then, the oil medium is added to the interior of the lower cylinder 1 through the oil inlet 6. At this time, when the oil medium flows between the lower cylinder 1 and the lower piston plate 15, a damping effect is generated. When the suspension is subjected to vertical vibration, the lower piston plate 15 moves vertically, changing the volume between the top of the upper piston plate 16 and the upper cylinder 12. When the vibration is transmitted to the lower piston plate 15 through the piston rod 3, the volume of the lower fixed plate 14 and the lower piston plate 15 changes during the movement of the lower piston plate 15. The oil medium flows in the damping hole to generate damping. The upper cylinder 12 adds the gas medium from the air inlet 8 to the lower cylinder 12.

The movement of the piston rod 3 will cause the third spring 504 to expand and contract, and the elastic effect of the third spring 504 can absorb the force. Therefore, when the road surface is relatively flat, most of the generated vibrations are dissipated through the upper cylinder body 12, thereby improving the driving comfort. At the same time, the movement of the piston rod 3 will cause the second spring 402 to expand and contract, and the elastic effect of the second spring 402 can absorb the force. When the road surface is bumpy and the vibration is large, the lower cylinder body 1 absorbs the vibration of the road surface, thereby improving the driving rigidity and enhancing the handling performance and safety.

8. A suspension cylinder type energy recovery method as claimed in any one of claims 1 to 7, characterized in that: The following steps are involved: Step 1: First, push the connecting blocks (20112) on both sides to drive the two movable columns (2018) to move and approach each other, and drive the two semicircular rings (20114) to approach each other through the fixing block (2019) and the mounting block (20110) until the piston rod (3) is clamped, and at the same time, drive the slider (2013) to move along the cross bar (2017) through the first rotating rod (2012), so that the first spring (2016) is stretched, and at the same time, the fixing block (2019) moves to drive the two external sleeves (2022) to move and move away from each other, and drive the inner rings (2023) to move away from each other, and then tighten the nuts (20111) on both sides to fix the position of the connecting block (20112), so that the two semicircular rings (20114) and the two inner rings (2023) limit the piston rod (3), and then the piston rod (3) can move vertically; Step 2: Then, the oil medium is added to the interior of the lower cylinder (1) through the oil inlet (6). When the oil medium flows between the lower cylinder (1) and the lower piston plate (15), a damping effect is generated. When the suspension is subjected to vertical vibration, the lower piston plate (15) moves vertically, changing the volume between the top of the upper piston plate (16) and the upper cylinder (12). When the vibration is transmitted to the lower piston plate (15) through the piston rod (3), the volume of the lower fixed plate (14) and the lower piston plate (15) changes during the movement of the lower piston plate (15). The oil medium flows in the damping hole to generate damping. The upper cylinder (12) is connected to the upper cylinder (12) by adding the gas medium to its interior through the air inlet (8). Step 3: Finally, the change in the internal air pressure of the upper cylinder (12) changes the volume of the left side of the movable plate (1008) inside the box (1001) through the ventilation pipe (1007), driving the movable plate (1008) to move horizontally, and at the same time driving the vertical block (1009) to move horizontally. Since there are magnetic flux lines between the two magnetic plates (1003), the vertical block (1009) moves between the two magnetic plates (1003) and cuts the magnetic flux lines, thereby generating current. The current is transmitted from the conductive rod (1002) and the wires at both ends thereof to the storage battery (1004), and the vibration energy can be recovered.
