[0008] Specifically, the first regulating assembly also includes a second one-way valve and a third one-way valve.

[0010] In which, the shock absorber mechanism also includes a second adjusting component, the second adjusting component includes a third pipeline, a fourth pipeline, a fifth pipeline, a sixth pipeline and a second regulating valve; the rodless chamber forms a second oil guide port, the oil storage chamber forms a third oil guide port, one end of the third pipeline is connected to the second oil guide port, and the other end is connected to the first end of the second regulating valve, one end of the fourth pipeline is connected to the third oil guide port, and the other end is connected to the second end of the second regulating valve, the third end and the fourth end of the second regulating valve are connected to the control distribution mechanism through the fifth pipeline and the sixth pipeline respectively.

[0011] Specifically, the second regulating valve is a two-position two-way reversing valve.

[0015] Compared with the prior art, the active energy feedback suspension system provided by the present invention has the following advantages:

[0016] The active energy feedback suspension system provided by the present invention includes a shock absorber mechanism, a distributed accumulator, a total accumulator, an oil replenishing mechanism and a control distribution mechanism; the shock absorber mechanism includes a piston, a working cylinder, an oil storage cylinder and a first one-way valve, the piston is arranged in the working cylinder to divide the working chamber of the working cylinder into a rod chamber and a rodless chamber, the working cylinder is arranged in the oil storage cylinder to form an oil storage chamber, and the oil storage chamber is connected to the working chamber, a first oil circuit is formed on the piston, the first one-way valve is arranged on the first oil circuit, one end of the first oil circuit is connected to the rodless chamber, and the other end is connected to the distributed accumulator; the distributed accumulator is connected to the control distribution mechanism, the control distribution mechanism and the total accumulator are connected to each other, the control distribution mechanism is connected to the shock absorber mechanism, and the oil replenishing mechanism is connected to the oil storage chamber through the control distribution mechanism.

[0018] Because the distributed accumulators are connected to the control and distribution mechanism, which in turn is connected to the master accumulator, once a certain amount of oil has accumulated in the distributed accumulators, it can be delivered to the control and distribution mechanism, where it is then transferred to the master accumulator for storage. Furthermore, when the stiffness of the shock absorber mechanism needs to be adjusted, the oil stored in the master accumulator is transferred through the control and distribution mechanism to the shock absorber's oil storage cylinder. Because the oil storage cylinder is connected to the working cylinder, the shock absorber's stiffness can be adjusted, thereby storing and utilizing the energy generated by road excitation.

[0019] In addition, the present invention also provides a vehicle comprising the above-mentioned active energy feedback suspension system.

[0020] A vehicle using the active energy-feeding suspension system provided in this application can store the energy generated by the road's excitation of the suspension and redistribute it to the corresponding vibrator mechanism as needed, so that the suspension can adapt to road conditions to improve driving comfort while reducing the energy consumption of the entire vehicle.

[0039] Example 1

[0040] like Figure 1 As shown, the present invention provides an active energy feedback suspension system, including a shock absorber mechanism, a distributed accumulator 5, a total accumulator 6, an oil replenishing mechanism and a control distribution mechanism 7; the shock absorber mechanism includes a piston 3, a working cylinder 1, an oil storage cylinder 2 and a first one-way valve 4, the piston 3 is arranged in the working cylinder 1, dividing the working chamber of the working cylinder 1 into a rod chamber 102 and a rodless chamber 101, the working cylinder 1 is arranged in the oil storage cylinder 2 to form an oil storage chamber 201, and the oil storage chamber 201 is connected to the working chamber, a first oil circuit 301 is formed on the piston 3, the first one-way valve 4 is arranged on the first oil circuit 301, one end of the first oil circuit 301 is connected to the rodless chamber 101, and the other end is connected to the distributed accumulator 5; the distributed accumulator 5 is connected to the control distribution mechanism 7, the control distribution mechanism 7 and the total accumulator 6 are connected to each other, the control distribution mechanism 7 is connected to the shock absorber mechanism, and the oil replenishing mechanism is connected to the oil storage chamber 201 through the control distribution mechanism 7.

[0041] Compared with the prior art, the active energy feedback suspension system provided by the present invention has the following advantages:

[0042] The active energy feedback suspension system provided by the present invention is configured such that the shock absorber mechanism includes a working cylinder 1 and an oil storage cylinder 2, and the piston 3 is arranged in the working cylinder 1, thereby forming a rod chamber 102, a rodless chamber 101 and an oil storage chamber 201. By forming a first oil circuit 301 in the piston 3 and adding a first one-way valve 4 in the first oil circuit 301, when the piston 3 moves downward in the working cylinder 1, a portion of the oil in the rod chamber 102 can enter the distributed accumulator 5 through the first oil circuit 301.

[0043] Because the distributed accumulator 5 is connected to the control and distribution mechanism 7, which is in turn connected to the master accumulator 6, once a certain amount of oil is stored in the distributed accumulator 5, it can be discharged to the control and distribution mechanism 7, where it is then transferred to the master accumulator 6 for storage. Furthermore, when the stiffness of the shock absorber mechanism needs to be adjusted, the oil stored in the master accumulator 6 can be transferred through the control and distribution mechanism 7 to the shock absorber mechanism's oil storage cylinder 2. Because the oil storage cylinder 2 is connected to the working cylinder 1, the stiffness of the shock absorber mechanism can be adjusted, thereby storing and utilizing the energy generated by road excitation.

[0044] In order to achieve overall stability of the vehicle, the shock absorber structure in this application has four, that is, the suspension system includes four shock absorber structures, corresponding to the four wheels of the vehicle, and the distributed energy accumulator 5 is set in a one-to-one correspondence with the shock absorber mechanism, so that the stiffness of the shock absorber structure can be accurately adjusted according to the road conditions.

[0045] It is understandable that due to different road conditions, the excitation conditions of the four shock absorber structures are different. The present application sets the distributed accumulator 5 in one-to-one correspondence with the shock absorber structure, so that the generated energy can be recovered according to different excitation conditions, and the corresponding distribution output is performed by controlling the distribution mechanism 7 to ensure the stability of the overall suspension system.

[0046] Example 2

[0047] Based on the structure provided in Example 1, optionally, as Figure 1-Figure 5 As shown, the shock absorber mechanism in the present application also includes a first adjusting component, which includes a first pipeline 8, a second pipeline 9 and a first regulating valve 10; the oil storage chamber 201 is formed with an oil outlet 2011, and the rodless chamber 101 is formed with an oil inlet 1011, and the oil inlet end of the first regulating valve 10 is connected to the oil outlet 2011 through the first pipeline 8, and the oil outlet end of the first regulating valve 10 is connected to the oil inlet 1011 through the second pipeline 9.

[0048] Preferably, the first regulating valve 10 in the present application is an electrically controlled damping valve, through which the damping of the working cylinder 1 can be adjusted, so that the overall suspension can adapt to situations with large road undulations and large undulation frequencies.

[0049] It is understandable that when the road surface is low in flatness and the undulation and undulation frequency are large, the shock absorber mechanism does not have time to adapt to such road conditions by changing its own height. Therefore, the damping size of the shock absorber mechanism is changed by the first regulating valve 10, so that it can better adapt to the road conditions.

[0050] The first regulating assembly in the present application also includes a second one-way valve 17 and a third one-way valve 18. The second one-way valve 17 is arranged in the oil inlet 1011, so that the oil in the oil storage chamber 201 flows in one direction to the rodless chamber 101. The third one-way valve 18 is arranged on the piston 3, and is used to make the oil in the rodless chamber 101 flow in one direction to the rod chamber 102. The rod chamber 102 is formed with a first oil guide port 1021, so that the rod chamber 102 is connected to the oil storage chamber 201.

[0051] Further preferably, in the present application, the second one-way valve 17 and the third one-way valve 18 are both composite disc valves, and the opening pressure of the second one-way valve 17 and the third one-way valve 18 is relatively large. When the vehicle is traveling on a road with large undulation and a large undulation frequency, the pressure in the working chamber increases, thereby enabling the second one-way valve 17 and the third one-way valve 18 to open. When the vehicle is running on a road with small undulation and a large undulation frequency, or when both the undulation and the undulation frequency are small, or when the undulation is large and the undulation frequency is small, the second one-way valve 17 and the third one-way valve 18 will not open.

[0052] like Figure 4 Combine Figure 5 As shown, when the vehicle travels on a road with a large undulation and a large undulation frequency, the second one-way valve 17 and the third one-way valve 18 are opened.

[0053] When the piston 3 moves downward in the working cylinder 1, the oil in the rodless chamber 101 will pass through the second one-way valve 17 into the rod chamber 102, and the oil in the rod chamber 102 will enter the oil storage chamber 201 through the first oil guide port 1021. The oil in the oil storage chamber 201 flows out from the oil outlet 2011 and enters the first regulating valve 10 through the first pipeline 8. The amount of oil entering the rodless chamber 101 through the oil inlet 1011 is controlled by the first regulating valve 10, so that the damping size of the shock absorber mechanism can be changed, that is, when the amount of oil entering the rodless chamber 101 is not less than the amount of oil flowing to the rod chamber 102 through the second one-way valve 17, the damping of the shock absorber mechanism is larger, and when the amount of oil entering the rodless chamber 101 is less than the amount of oil flowing to the rod chamber 102 through the second one-way valve 17, the damping of the shock absorber mechanism is smaller.

[0054] When the piston 3 moves upward in the working cylinder 1, the oil in the rod chamber 102 can only enter the oil reservoir 201 through the first oil guide port 1021, and the oil in the oil reservoir 201 can only flow to the first regulating valve 10 through the oil outlet 2011. Therefore, when the flow rate of the first regulating valve 10 is small, the amount of oil flowing out of the oil reservoir 201 is small, so that less oil can flow from the rod chamber 102 into the oil reservoir 201, thereby increasing the damping of the shock absorber mechanism. When the flow rate of the first regulating valve 10 is large, the amount of oil flowing out of the oil reservoir 201 is large, and the outflowing oil passes through the first regulating valve 10 and enters the rodless chamber 101, thereby increasing the upward movement speed of the piston 3. That is, the damping in this state is small.

[0055] Example 3

[0056] Based on the above embodiment, optionally, as Figure 1 As shown, the shock absorber mechanism in the present application also includes a second adjusting component, which includes a third pipeline 11, a fourth pipeline 12, a fifth pipeline 13, a sixth pipeline 14 and a second regulating valve 15; the rodless chamber 101 is formed with a second oil guide port 1012, and the oil storage chamber 201 is formed with a third oil guide port 2012, one end of the third pipeline 11 is connected to the second oil guide port 1012, and the other end is connected to the first end of the second regulating valve 15, one end of the fourth pipeline 12 is connected to the third oil guide port 2012, and the other end is connected to the second end of the second regulating valve 15, and the third end and the fourth end of the second regulating valve 15 are respectively connected to the control distribution mechanism 7 through the fifth pipeline 13 and the sixth pipeline 14.

[0057] Preferably, the second regulating valve 15 in the present application is a two-position two-way reversing valve, and further preferably, the second regulating valve 15 is a two-position two-way electromagnetic reversing valve, through which the height of the shock absorber mechanism can be adjusted according to actual road conditions.

[0058] It is understood that in some embodiments, the second regulating valve 15 of the present application is directly connected to the oil tank 20 via the fifth and sixth pipelines 13 and 14. However, to ensure accurate adjustment of the height of the shock absorber mechanism, it is preferred that the fifth and sixth pipelines 13 and 14 of the present application be connected to the control distribution mechanism 7. The control distribution mechanism 7 can be used to fill the oil in the oil tank 20 into the corresponding shock absorber mechanism according to actual needs. Furthermore, when the second regulating valve 15 is in operation, the first regulating valve 10 is in a closed state.

[0059] like Figure 6 Combine Figure 7As shown, when the height of the shock absorber mechanism needs to be adjusted down, that is, the piston 3 moves downward in the working cylinder 1, the shock absorber mechanism contracts, and therefore, the oil in the rodless chamber 101 needs to flow out. At this time, the second regulating valve 15 is in the first position, that is, the first interface is connected to the third interface, and the second interface is connected to the fourth interface. Since the third interface is always the oil outlet interface and the fourth interface is always the oil inlet interface, the oil in the rodless chamber 101 enters the first interface of the second regulating valve 15 through the first pipeline 8, and flows through the third interface into the fifth pipeline 13 and flows back to the oil tank 20. Correspondingly, the oil in the oil tank 20 enters the second regulating valve 15 through the sixth pipeline 14, and enters the second pipeline 9 from the second interface of the second regulating valve 15 and finally flows into the oil storage chamber 201, so that the oil in the oil storage chamber 201 can enter the rod chamber 102 through the first oil guide port 1021, thereby causing the piston 3 to move downward in the working cylinder 1, and then can realize active adjustment of the position of the piston 3 according to the road conditions, and realize active adjustment of the height of the shock absorber mechanism.

[0060] Correspondingly, when the height of the shock absorber mechanism needs to be increased, that is, the piston 3 moves upward in the working cylinder 1 and the shock absorber mechanism extends. Therefore, it is necessary to allow oil to enter the rodless chamber 101 and oil to exit the rod chamber 102. At this time, the second regulating valve 15 is changed to the second position, that is, the first interface is connected to the fourth interface, and the second interface is connected to the third interface, so that the oil entering the fourth interface flows into the first pipeline 8 and finally enters the rodless chamber 101, pushing the piston 3 to move upward, and the upward movement of the piston 3 will compress the rod chamber 102, so that the oil in the rod chamber 102 enters the oil storage chamber 201 through the first oil guide port 1021, and flows back to the oil tank 20 through the second regulating valve 15 through the third oil guide port 2012, thereby completing the action of increasing the height of the shock absorber mechanism.

[0061] It should be noted that the damping adjustment of the shock absorber mechanism in Example 2 of this application is mainly applicable to road conditions with large road undulations and large undulation frequencies. For road conditions with large road undulations and small undulation frequencies, the shock absorber mechanism can respond accordingly due to the small undulation frequency. Therefore, the shock absorber height is changed to adapt. However, there are also road conditions with small undulations and large undulation frequencies, as well as conditions with both small undulations and small undulation frequencies. Since the undulations are small, there is no need to adjust the shock absorber mechanism. Therefore, based on the above two situations, Figure 2 As shown, the active energy feedback suspension provided by the present invention further includes a buffer member 16, and the buffer member 16 is connected to the shock absorber mechanism.

[0062] The buffer member 16 can achieve the shock absorption and buffering function of the entire vehicle without adjusting the shock absorber mechanism, thereby further reducing energy consumption.

[0063] It is understood that the oil replenishment mechanism in the present application includes an oil tank 20 and an oil pump 19. The oil tank 20 is connected to the oil pump 19, and the oil outlet of the oil pump 19 is connected to the control distribution mechanism 7. The oil pump 19 can pump the oil in the oil tank 20 to the control distribution mechanism 7, and then the control distribution mechanism 7 distributes the oil according to the needs of the four shock absorber mechanisms, thereby achieving precise adjustment of the shock absorber mechanisms.

[0064] It should be additionally explained here that, preferably, the control distribution mechanism 7 in the present application is a HCU (Hybrid Control Unit) hybrid power controller.

[0065] In addition, the present invention also provides a vehicle comprising the above-mentioned active energy feedback suspension system.

[0066] A vehicle using the active energy-feeding suspension system provided in this application can store the energy generated by the road's excitation of the suspension and redistribute it to the corresponding vibrator mechanism as needed, so that the suspension can adapt to road conditions to improve driving comfort while reducing the energy consumption of the entire vehicle.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
