[0032] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.
[0033] Reference below Figure 1-Figure 6 A suspension system 100 according to an embodiment of the present invention is described. The suspension system 100 may be applied to a vehicle.
[0034] Combination Figure 1-Figure 6 As shown, the suspension system 100 according to the utility model can mainly include: a shock absorber 10, an energy storage module 20 and an active pump 40, wherein a movable piston 15 is arranged in the shock absorber 10, and the piston 15 divides the interior of the shock absorber 10 into an upper chamber 13 and a lower chamber 14, and a tension oil outlet 16 and a compression oil outlet 17 are arranged on the shock absorber 10, and the tension oil outlet 16 is connected to the upper chamber 13, and the compression oil outlet 17 is connected to the lower chamber 14, and the energy storage module 20 is arranged at intervals from the shock absorber 10, and the energy storage module 20 includes a damping regulating valve 21 and an accumulator 22, and the damping regulating valve 21 includes a valve seat 21 3. A first damping valve body 211 and a second damping valve body 212. The first damping valve body 211, the second damping valve body 212 and the accumulator 22 are all arranged on the valve seat 213. The accumulator 22 is connected with the stretching oil outlet 16 and the compression oil outlet 17. The first damping valve body 211 is arranged between the stretching oil outlet 16 and the accumulator 22. The second damping valve body 212 is arranged between the compression oil outlet 17 and the accumulator 22. The active pump 40 is provided with a first port 421 and a second port 422. The first port 421 is connected with the stretching oil outlet 16, and the second port 422 is connected with the compression oil outlet 17.
[0035] Specifically, by providing a movable piston 15 in the shock absorber 10, the piston 15 can separate the interior of the shock absorber 10 into an upper chamber 13 and a lower chamber 14.
[0036] It is understandable that during the use of the shock absorber 10, the shock-absorbing oil moves to constitute the buffering performance and reset performance of the shock absorber 10. For example, when the shock absorber 10 needs to perform shock-absorbing and buffering, the force is suitable for acting on the piston 15, and the piston 15 is suitable for transmitting the force to the shock-absorbing oil in the lower chamber 14 to drive the shock-absorbing oil in the lower chamber 14 to flow out from the compression oil outlet 17, thereby playing a role in shock-absorbing and buffering the force. When the shock absorber 10 needs to be reset, the shock-absorbing oil in the damping regulating valve 21 is suitable for entering the upper chamber 13 of the shock absorber 10 through the tension oil outlet 16 to drive the piston 15 to reset.
[0037] Furthermore, the energy storage module 20 and the shock absorber 10 are arranged at intervals, which can reduce the volume of the shock absorber 10, facilitate the arrangement of the shock absorber 10 on the vehicle, and simplify the internal structure of the shock absorber 10, thereby reducing the risk of oil leakage inside the shock absorber 10.
[0038] In addition, the energy storage module 20 includes an accumulator 22 and a damping regulating valve 21, and the accumulator 22 is connected to the compression oil outlet 17 and the extension oil outlet 16 respectively. The damping regulating valve 21 includes a valve seat 213, a first damping valve body 211 and a second damping valve body 212. The first damping valve body 211 is arranged between the accumulator 22 and the extension oil outlet 16 and the accumulator 22, and the second damping valve body 212 is arranged between the compression oil outlet 17 and the accumulator 22. In this way, even in the first damping Oil leakage between the valve body 211 and the tension oil outlet 16 of the shock absorber 10, or between the first damping valve body 211 and the accumulator 22, or between the second damping valve body 212 and the compression oil outlet 17 of the shock absorber 10, or between the second damping valve body 212 and the accumulator 22 can also be easily observed, so that the oil leakage can be inspected and repaired in time, which can facilitate the user's use and maintenance of the suspension system 100.
[0039] Furthermore, the first damping valve body 211, the second damping valve body 212 and the accumulator 22 are all arranged on the valve seat 213, which can not only improve the stability and reliability of the installation of the first damping valve body 211, the second damping valve body 212 and the accumulator 22, but also further improve the stability and smoothness of the oil circulation flow.
[0040] In some embodiments of the utility model, by setting a first port 421 and a second port 422 on the active pump 40, and making the first port 421 communicate with the stretching oil outlet 16, and the second port 422 communicate with the compression oil outlet 17, the active pump 40 includes a hydraulic pump 42 and a driving member 41, the driving member 41 is transmission-connected to the hydraulic pump 42, the first port 421 and the second port 422 are set on the hydraulic pump 42, the driving member 41 can selectively drive the oil in the hydraulic pump 42 to flow to the stretching oil outlet 16 or the compression oil outlet 17 through the first port 421 or the second port 422 according to the working condition of the vehicle, or make the oil in the shock absorber 10 flow back to the first port 421 or the second port 422 through the stretching oil outlet 16 or the compression oil outlet 17, so that the active pump 40 adjusts the working mode of the suspension system 100, which can further improve the stability and reliability of the suspension system 100.
[0041] Combination Figure 2 and Figure 5As shown, the stretching oil outlet 16 includes a first stretching oil outlet 161 and a second stretching oil outlet 162, the compression oil outlet 17 includes a first compression oil outlet 171 and a second compression oil outlet 172, the first stretching oil outlet 161 and the first compression oil outlet 171 are both connected to the accumulator 22, the first damping valve body 211 is arranged between the first stretching oil outlet 161 and the accumulator 22, the second damping valve body 212 is arranged between the first compression oil outlet 171 and the accumulator 22, the first through port 421 is connected to the first stretching oil outlet 161, the second through port 422 is connected to the second stretching oil outlet 162, and the energy storage module 20 and the active pump 40 are arranged in parallel.
[0042] Specifically, by connecting the first stretching oil outlet 161 and the first compression oil outlet 171 to the accumulator 22, the first damping valve body 211 is arranged between the first stretching oil outlet 161 and the accumulator 22, the second damping valve body 212 is arranged between the first compression oil outlet 171 and the accumulator 22, and the first through port 421 is connected to the first stretching oil outlet 161, and the second through port 422 is connected to the second stretching oil outlet 162, so that the connection between the energy storage module 20 and the shock absorber 10 can be stable and smooth, and the connection between the active pump 40 and the shock absorber 10 can be stable and smooth.
[0043] Furthermore, in such an arrangement, the active pump 40 and the energy storage module 20 are arranged in parallel, so that the active pump 40 and the energy storage module 20 can work independently, and the flow paths of the oil do not interfere with each other, which can further improve the stability and reliability of the suspension system 100.
[0044] Combination Figure 2 , Figure 5 and Figure 6 As shown, the shock absorber 10 also includes a base 11 and a cylinder 12, the cylinder 12 is arranged on the base 11, the piston 15 is movably arranged in the cylinder 12 and divides the interior of the shock absorber 10 into an upper chamber 13 and a lower chamber 14, the first stretching oil outlet 161 and the first compression oil outlet 171 are arranged on the first side 34 of the base 11, the second stretching oil outlet 162 and the second compression oil outlet 172 are arranged on the second side 35 of the base 11, and the first side 34 and the second side 35 are arranged opposite to each other in the second direction.
[0045] Specifically, by arranging the cylinder 12 on the base 11, the piston 15 is movably arranged in the cylinder 12 and the interior of the shock absorber 10 is divided into an upper chamber 13 and a lower chamber 14, so that the shock absorber 10 can be more stable and reliable.

The first side 34 and the second side 35 are arranged relative to each other in the second direction. This can not only further prevent the communication path between the energy storage module 20 and the shock absorber 10 from interfering with the communication path between the active pump 40 and the shock absorber 10, but also further improve the stability of the connection between the energy storage module 20 and the shock absorber 10, as well as the stability of the connection between the active pump 40 and the shock absorber 10. Moreover, since the first side 34 and the second side 35 are arranged relative to each other, when oil leakage occurs, the location of the oil leakage is also easy to identify, so that the corresponding components can be repaired and replaced, which can further improve the user experience of the suspension system 100.
[0046] Combination Figure 2 and Figure 5 As shown, there is one accumulator 22, and the first stretching oil outlet 161 and the first compression oil outlet 171 are both connected to one accumulator 22. Specifically, by connecting the first stretching oil outlet 161 and the first compression oil outlet 171 to one accumulator 22, and setting the first damping valve body 211211 between one accumulator 22 and the first stretching oil outlet 161, and setting the first damping valve body 211211 between one accumulator 22 and the first compression oil outlet 171, the structural design of the energy storage module 20 can be further simplified under the premise of meeting the working requirements.

Specifically, the first one-way valve 23 is arranged between the accumulator 22 and the first stretching oil outlet 161, and the first one-way valve 23 is arranged in parallel with the first damping valve body 211. In this way, when the oil in the first stretching oil outlet 161 of the shock absorber 10 flows to the accumulator 22, it needs to pass through the first one-way valve 23. The first one-way valve 23 can prevent the oil from flowing back to the first stretching oil outlet 161 of the shock absorber 10. When the oil in the accumulator 22 flows to the first stretching oil outlet 161 of the shock absorber 10, since the first one-way valve 23 is in a closed state in this flow direction, it can be ensured that the oil can only pass through the first damping valve body 211 and enter the shock absorber 10, which can further optimize the structural design of the suspension system 100.
[0048] Combination Figure 2 As shown, it also includes a second one-way valve 24 , which is arranged between the accumulator 22 and the first compressed oil outlet 171 , and the second one-way valve 24 is arranged in parallel with the second damping valve body 212 . Specifically, the second one-way valve 24 is arranged between the accumulator 22 and the first compressed oil outlet 171, and the second one-way valve 24 is arranged in parallel with the second damping valve body 212. In this way, when the oil in the first compressed oil outlet 171 of the shock absorber 10 flows to the accumulator 22, it needs to pass through the second one-way valve 24. The second one-way valve 24 can prevent the oil from flowing back to the first compressed oil outlet 171 of the shock absorber 10. When the oil in the accumulator 22 flows to the first compressed oil outlet 171 of the shock absorber 10, since the second one-way valve 24 is in a closed state in this flow direction, it can be ensured that the oil can only pass through the second damping valve body 212 and enter the shock absorber 10, so that the structural design of the suspension system 100 can be further optimized.
