Description

Technical Field

[0001] This application relates to the field of suspension technology, and more particularly to a hydraulic buffer block system, a suspension system, and a vehicle. Background Technology

[0002] Buffer blocks are typically installed on the suspension and are spaced apart from the suspension arms or axles. The position of the buffer block affects the clearance between it and the arms or axles. Therefore, the position of the buffer block is related to the vehicle's ride comfort and rollover resistance. In practical applications, the position of the buffer block is fixed, which makes it impossible to balance ride comfort and rollover resistance. Utility Model Content

[0003] In view of this, the purpose of this application is to provide a hydraulic buffer block system, suspension system and vehicle to solve the problem that the fixed position of the buffer block makes it impossible to balance comfort and anti-rollover capability.

[0004] To achieve the above objectives, this application provides a hydraulic buffer block system, comprising: A hydraulic buffer block assembly, comprising a connected hydraulic module and a buffer block; The hydraulic oil power module and the energy storage component are both connected to the hydraulic module to coordinate the extension and retraction of the hydraulic buffer block assembly and change the position of the buffer block.

[0005] Furthermore, the hydraulic module includes a hydraulic cylinder and a telescopic component. The telescopic component includes an active end and a free end. The active end is located inside the hydraulic cylinder, dividing the hydraulic cylinder into a first region and a second region. The first region is located away from the buffer block. The free end passes through the hydraulic cylinder and connects to the buffer block. The hydraulic oil power module is connected to the first region.

[0006] Furthermore, the energy storage component includes a first energy storage element and a second energy storage element, wherein the first energy storage element is connected to the first region and the second energy storage element is connected to the second region.

[0007] Furthermore, the hydraulic oil power module includes an electro-hydraulic pump and a reservoir. The electro-hydraulic pump is located inside the reservoir and is used to draw hydraulic oil from the reservoir to the hydraulic buffer block assembly, or to draw hydraulic oil from the hydraulic buffer block assembly to the reservoir.

[0008] Based on the same inventive concept, this application also provides a suspension system, including the hydraulic buffer block system as described above, and having a standard mode in which the working end is located in the middle of the hydraulic cylinder, wherein in the standard mode, the buffer block is located in a standard position. When the suspension system switches from the standard mode to the first mode, the first area is connected to the hydraulic oil power module, and the second area is connected to the second energy storage component, so that the actuating end compresses the first area, and the free end drives the buffer block to move to the preset position in the first mode. After the buffer block reaches the preset position, the hydraulic module, the hydraulic oil power module, and the energy storage component are all turned off.

[0009] Furthermore, when the suspension system switches from the standard mode to the second mode, the first area is connected to the hydraulic oil power module, and the second area is connected to the second energy storage component, so that the actuating end compresses the second area, and the free end drives the buffer block to move to the preset position in the second mode. After the buffer block reaches the preset position, the hydraulic module, the hydraulic oil power module, and the energy storage component are all turned off.

[0010] Furthermore, the suspension system includes a front suspension and a rear suspension, both of which are equipped with hydraulic buffer block assemblies and energy storage assemblies; When the suspension system switches from the standard mode to the third mode, the hydraulic buffer block assembly of the rear suspension is disconnected from the energy storage assembly and the hydraulic power module. The buffer block is in the standard position. The first area of ​​the front suspension is connected to the hydraulic power module, and the second area is connected to the second energy storage component. This causes the working end to compress the second area, and the free end to drive the buffer block to move to the preset position in the third mode. After the buffer block reaches the preset position, the hydraulic module, the hydraulic power module, and the energy storage assembly are all disconnected.

[0011] Furthermore, when the suspension system switches from the standard mode to the fourth mode, the hydraulic buffer block assembly of the front suspension is disconnected from the energy storage assembly and the hydraulic power module, the buffer block is in the standard position, the first area of ​​the rear suspension is connected to the hydraulic power module, and the second area is connected to the second energy storage component, so that the working end compresses the second area, and the free end drives the buffer block to move to the preset position in the third mode. After the buffer block reaches the preset position, the hydraulic module, the hydraulic power module, and the energy storage assembly are all disconnected.

[0012] Furthermore, when the suspension system switches from the standard mode to the fifth mode, the hydraulic buffer block assembly is shut off from the hydraulic oil power module and connected to the energy storage component. The buffer block is used to adaptively adjust its position under the action of the energy storage component.

[0013] Based on the same inventive concept, this application also provides a vehicle including the suspension system described above.

[0014] As can be seen from the above, this application provides a hydraulic buffer block system, suspension system, and vehicle. The hydraulic buffer block system includes a hydraulic buffer block assembly, a hydraulic power module, and an energy storage component. The hydraulic buffer block assembly includes a connected hydraulic module and a buffer block. The hydraulic module is connected to the hydraulic power module and the energy storage component to extend and retract under the individual or combined action of the hydraulic power module and the energy storage component, thereby changing the position of the buffer block. This allows the position of the buffer block to match the vehicle's driving needs, avoiding the problem of a fixed buffer block position leading to a failure to balance comfort and rollover resistance. This application connects the hydraulic power module and the energy storage component to the hydraulic module, enabling the hydraulic power module and the energy storage component to work together to adjust the extension and retraction of the hydraulic buffer block assembly, or the energy storage component to adjust the extension and retraction of the hydraulic buffer block assembly, under different operating conditions. This allows the hydraulic buffer block system to have different buffer block positions under different operating conditions, solving the problem of a fixed buffer block position failing to balance comfort and rollover resistance, and improving the adaptability of the hydraulic buffer block system under different operating conditions.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0019] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in the embodiments of this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0020] In related technologies, such as Figure 1A , Figure 1B and Figure 1C As shown, the vehicle's suspension 01 includes a front suspension 10 and a rear suspension 20. Both the front suspension 10 and the rear suspension 20 are equipped with buffer blocks 02. The front suspension 10 includes a frame and a control arm, and the rear suspension 20 includes a frame and an axle. The buffer block 02 of the front suspension 10 is located on the frame and is spaced apart from the control arm. The buffer block 02 of the rear suspension 20 is located on the frame and is spaced apart from the axle. The gap between the buffer block and the control arm or the axle is called the buffer block gap.

[0021] Larger gaps in the buffer blocks provide ample buffer space for vehicles when traversing bumpy roads, improving vehicle comfort. However, when vehicles are cornering at high speeds (with significant lateral acceleration), excessive gaps in the buffer blocks can lead to large lateral tilts, which is detrimental to the vehicle's roll resistance.

[0022] Based on this, this application proposes a hydraulic buffer block system, a suspension system, and a vehicle to solve the problem that the fixed position of the buffer block leads to excessively large or small gaps between the buffer blocks, thus failing to balance vehicle driving comfort and anti-rollover capability.

[0023] The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0024] In some embodiments, a hydraulic buffer block system, such as Figures 2-7 As shown, it includes: The hydraulic buffer block assembly 110 includes a hydraulic module 111 and a buffer block 112 connected to each other; The hydraulic oil power module 120 and the energy storage component 130 are both connected to the hydraulic module 111 to coordinate the extension and retraction of the hydraulic buffer block assembly 110 and change the position of the buffer block 112.

[0025] Specifically, the hydraulic module 111 is fixedly installed, and the buffer block 112 is positioned towards the suspension so that it moves with the hydraulic module 111, changing the gap between the buffer block 112 and the suspension. The hydraulic power module 120 and the energy storage assembly 130 are both connected to the hydraulic module 111, allowing adjustment of the extension and retraction of the hydraulic module 111 by switching them on or off. The hydraulic module 111 is connected to the buffer block 112; when the hydraulic module 111 extends or retracts, the buffer block 112 extends and retracts accordingly, thus changing its position.

[0026] When the energy storage component 130 is connected to the hydraulic module 111, it is used to store energy during the extension and retraction of the hydraulic module 111 or to apply force to the hydraulic module 111 to adjust its extension and retraction. It should be noted that the force exerted by the energy storage component 130 to adjust the extension and retraction of the hydraulic module 111 is limited, and the extension and retraction adjustment stroke of the hydraulic module 111 is small. When the hydraulic module 111 is adjusted to a large extent, the hydraulic oil power module 120 needs to be activated. When the hydraulic oil power module 120 is activated, it is connected to the hydraulic module 111, and the energy storage component 130 stores energy with the help of the hydraulic oil power module 120 for subsequent adjustment of the hydraulic module 111.

[0027] The energy storage component 130 enables energy recovery and also provides a certain degree of extension and retraction for the hydraulic module 111, which is beneficial to the control precision of the hydraulic module 111. The energy storage component 130 can be an energy accumulator.

[0028] For example, the vehicle has a front suspension 10 and a rear suspension 20. Each of the front suspension 10 and the rear suspension 20 is provided with a hydraulic buffer block assembly 110 on the left and right sides, that is, the vehicle is provided with four hydraulic buffer block assemblies 110. Correspondingly, each hydraulic buffer block assembly 110 is connected to an energy storage assembly 130. The hydraulic oil power module 120 can be connected to all four hydraulic buffer block assemblies 110 at the same time, or four hydraulic oil power modules 120 can be provided to be connected to the four hydraulic buffer block assemblies 110 respectively.

[0029] It should be noted that the number of hydraulic oil power modules 120 can be set according to actual usage needs and in accordance with the principle of green environmental protection. In this application, the number of hydraulic oil power modules 120 can be one, which is connected to multiple hydraulic buffer block assemblies 110.

[0030] More specifically, such as Figure 8 As shown, the buffer block 112 includes a connecting end 112-1, a buffer block body 112-2, and a contact end 112-3 connected together. The connecting end 112-1 is connected to the hydraulic module 111, and the contact end 112-3 is positioned away from the hydraulic module 111 to allow for contact or clearance with the suspension as the hydraulic module 111 extends and retracts, thereby adjusting the buffer block clearance. The contact end 112-3 has an arc structure to increase the elastic force between the buffer block 112 and the suspension when it contacts the suspension, preventing stress concentration from damaging the suspension and the buffer block 112, and thus improving the service life of the hydraulic buffer block system 100. Furthermore, the orthographic projection area of ​​the connecting end 112-1 on the horizontal plane is smaller than that of the contact end 112-3 on the horizontal plane, increasing the contact area between the contact end 112-3 and the suspension, which improves the contact stability between the buffer block 112 and the suspension.

[0031] In this embodiment, the hydraulic buffer block system 100 includes a hydraulic buffer block assembly 110, a hydraulic power module 120, and an energy storage component 130. The hydraulic buffer block assembly 110 includes a hydraulic module 111 and a buffer block 112 connected to each other. The hydraulic module 111 is connected to the hydraulic power module 120 and the energy storage component 130 to extend and retract under the individual or combined action of the hydraulic power module 120 and the energy storage component 130, thereby driving the buffer block 112 to change its position, so that the position of the buffer block 112 matches the vehicle's driving needs, avoiding the problem that the vehicle cannot balance comfort and anti-rollover capability due to the fixed position of the buffer block 112. This application sets up a hydraulic oil power module 120 and an energy storage component 130 connected to the hydraulic module 111. When the vehicle is in different working conditions, the hydraulic oil power module 120 and the energy storage component 130 can be selected to cooperate in adjusting the extension and retraction of the hydraulic buffer block assembly 110, or the energy storage component 130 can be selected to adjust the extension and retraction of the hydraulic buffer block assembly 110. This allows the hydraulic buffer block system 100 to have different positions for the buffer block 112 under different working conditions, solving the problem that a fixed position of the buffer block 112 cannot simultaneously ensure comfort and anti-rollover capability. This is beneficial to improving the adaptability of the hydraulic buffer block system 100 under different working conditions.

[0032] In some embodiments, the hydraulic module 111 includes a hydraulic cylinder 111-1 and a telescopic member 111-2. The telescopic member 111-2 includes an actuating end 111-21 and a free end 111-22. The actuating end 111-21 is located inside the hydraulic cylinder 111-1, dividing the hydraulic cylinder 111-1 into a first region 111-11 and a second region 111-12. The first region 111-11 is located away from the buffer block 112. The free end 111-22 passes through the hydraulic cylinder 111-1 and is connected to the buffer block 112. The hydraulic oil power module 120 is connected to the first region 111-11.

[0033] Specifically, the actuating end 111-21 of the telescopic member 111-2 is perpendicular to the telescopic direction of the telescopic member 111-2, so that when the telescopic member 111-2 extends or retracts, the actuating end 111-21 compresses the first region 111-11 or the second region 111-12, and the free end 111-22 is connected to the side of the actuating end 111-21 near the second region 111-12, so as to pass through the hydraulic cylinder 111-1 and connect to the buffer block 112.

[0034] The hydraulic oil power module 120 is connected to the first region 111-11 to apply force to the first region 111-11, change the amount of hydraulic oil in the first region 111-11, thereby causing the actuating end 111-21 to move, causing the telescopic member 111-2 to extend and retract, and changing the position of the buffer block 112.

[0035] In this embodiment, the hydraulic module 111 drives the expansion and contraction of the buffer block 112 through the expansion and contraction of the telescopic member 111-2, thereby changing the position of the buffer block 112. The actuating end 111-21 of the telescopic member 111-2 divides the hydraulic cylinder 111-1 into a first region 111-11 and a second region 111-12. The hydraulic oil power module 120 is connected to the first region 111-11 to adjust the oil volume within the first region 111-11. When the oil volume changes, causing a change in pressure within the first region 111-11, the actuating end 111-21 moves under the action of either the first region 111-11 or the second region 111-12, so that the pressures within the second region 111-12 and the first region 111-11 are equalized. This achieves the effect of adjusting the position of the telescopic member 111-2 and the buffer block 112 through the hydraulic oil power module 120. The hydraulic oil power module 120 can quickly adjust the position of the buffer block 112 to meet the requirements.

[0036] In some embodiments, the energy storage component 130 includes a first energy storage element 131 and a second energy storage element 132, wherein the first energy storage element 131 is connected to the first region 111-11 and the second energy storage element 132 is connected to the second region 111-12.

[0037] Specifically, the first energy storage unit 131 is used to accumulate hydraulic oil when the first region 111-11 shrinks, and injects hydraulic oil into the first region 111-11 when it is necessary to control the extension of the telescopic member 111-2, so as to achieve the purpose of adjusting the position of the buffer block 112. The second energy storage unit 132 is used to accumulate hydraulic oil when the second region 111-12 shrinks, and injects hydraulic oil into the second region 111-12 when it is necessary to control the extension of the telescopic member 111-2, so as to achieve the purpose of adjusting the position of the buffer block 112.

[0038] For example, both the first energy storage element 131 and the second energy storage element 132 are energy storage devices.

[0039] In this embodiment, the arrangement of the first energy storage component 131 and the second energy storage component 132 enables the energy storage assembly 130 to collect and release hydraulic oil in the first region 111-11 and the second region 111-12, which is beneficial for the flexible control of the telescopic component 111-2.

[0040] In some embodiments, the hydraulic oil power module 120 includes an electro-hydraulic pump 121 and a reservoir 122. The electro-hydraulic pump 121 is located inside the reservoir 122. The electro-hydraulic pump 121 is used to draw hydraulic oil from the reservoir 122 to the hydraulic buffer block assembly 110, or to draw hydraulic oil from the hydraulic buffer block assembly 110 to the reservoir 122.

[0041] Specifically, the electro-hydraulic pump 121 is located between the reservoir 122 and the hydraulic buffer block assembly 110, that is, the electro-hydraulic pump 121 is located between the reservoir 122 and the first region 111-11 of the hydraulic module 111. When the electro-hydraulic pump 121 draws hydraulic oil from the first region 111-11 into the reservoir 122, the actuating end 111-21 of the telescopic member 111-2 compresses the first region 111-11, causing the telescopic member 111-2 to contract. When the electro-hydraulic pump 121 draws hydraulic oil from the reservoir 122 into the first region 111-11, the actuating end 111-21 of the telescopic member 111-2 compresses the second region 111-12, causing the telescopic member 111-2 to extend. The hydraulic oil power module 120 controls the extension and retraction of the telescopic member 111-2 by controlling the forward and reverse rotation of the electro-hydraulic pump 121, thereby realizing the position adjustment of the buffer block 112.

[0042] In this embodiment, the hydraulic oil power module 120 includes an electro-hydraulic pump 121 and a reservoir 122. By controlling the forward and reverse rotation of the electro-hydraulic pump 121, the extension and retraction of the telescopic member 111-2 are controlled, thereby realizing the position adjustment of the buffer block 112.

[0043] It should be noted that the hydraulic oil power module 120 is connected to the hydraulic buffer block assembly 110 via a solenoid valve 140, the first energy storage device 131 is connected to the first region 111-11 via a solenoid valve 140, and the second energy storage device 132 is connected to the second region 111-12 via a solenoid valve 140. By controlling the opening and closing of the solenoid valve 140, the hydraulic oil power module 120 and the hydraulic buffer block assembly 110 can be switched on and off, the first energy storage device 131 and the first region 111-11 can be switched on and off, and the second energy storage device 132 and the second region 111-12 can be switched on and off.

[0044] Based on the same inventive concept, this application also provides a suspension system, such as Figure 2 and Figure 3 As shown, the hydraulic buffer block system 100 described above is included, and has a standard mode in which the working end 111-21 is located in the middle of the hydraulic cylinder 111-1, wherein the buffer block 112 is located in a standard position in the standard mode. When the suspension system switches from the standard mode to the first mode, the first region 111-11 is connected to the hydraulic oil power module 120, and the second region 111-12 is connected to the second energy storage component 132, so that the actuating end 111-21 compresses the first region 111-11, and the free end 111-22 drives the buffer block 112 to move to the preset position in the first mode. After the buffer block 112 reaches the preset position, the hydraulic module 111, the hydraulic oil power module 120, and the energy storage component 130 are all turned off.

[0045] Specifically, the suspension system includes the hydraulic buffer block system 100 and the suspension. The hydraulic buffer block system 100 is located on the frame of the suspension 01, and the buffer block 112 is arranged facing the axle or control arm of the suspension 01. The buffer block gap can be adjusted by adjusting the position of the buffer block 112, thereby adjusting the anti-bump and anti-rollover capabilities of the suspension system.

[0046] When the suspension system is in standard mode, the actuating end 111-21 of the telescopic member 111-2 is located in the middle of the hydraulic cylinder 111-1, and the buffer block gap is a medium gap (that is, when the maximum value of the buffer block gap is L, the medium gap is L / 2). The comfort and anti-rollover capability of the suspension system in standard mode are generally average, and it is suitable for driving on relatively flat roads with less twisting.

[0047] The suspension system switches to different modes based on the standard mode to adjust the position of the buffer block 112, thereby enabling the suspension system to improve the corresponding comfort or anti-rollover capability according to its driving needs.

[0048] When the suspension system switches from standard mode to the first mode, it indicates that the vehicle is traveling on a bumpy road and the comfort of the suspension system needs to be improved. Therefore, when the vehicle controller receives the switch from standard mode to the first mode, it controls the first region 111-11 of the hydraulic cylinder 111-1 to be connected to the hydraulic oil power module 120, and the second region 111-12 of the hydraulic cylinder 111-1 to be connected to the second energy storage device 132. The hydraulic oil power module 120 is used to draw hydraulic oil from the first region 111-11 to compress the first... In region 111-11, the telescopic member 111-2 retracts, which in turn causes the buffer block 112 to retract, increasing the gap between the buffer blocks. When the buffer block 112 retracts and moves to the preset position corresponding to the first mode, the vehicle controller controls the first region 111-11 to shut off the hydraulic oil power module 120 and controls the second region 111-12 to shut off the second energy storage device 132. Consequently, the position of the working end 111-21 in the hydraulic cylinder 111-1 is fixed, and the gap between the buffer block 112 and the suspension is fixed, and the gap between the buffer block 112 and the suspension is increased compared to the standard mode, which is beneficial to improving the comfort of the suspension system.

[0049] It should be noted that when the buffer block 112 moves to the preset position corresponding to the first mode, the actuating end 111-21 is in contact with the side of the hydraulic cylinder 111-1 away from the buffer block 112, and the gap of the buffer block is at its maximum. In the first mode, the suspension system has the strongest comfort.

[0050] In this embodiment, the suspension system controls the movement of the actuating end 111-21 within the hydraulic cylinder 111-1 by adjusting the conductivity of the first region 111-11 and the second region 111-12, thereby driving the buffer block 112 to move and adjusting the gap of the buffer block. This allows the suspension system to provide strong comfort in the first mode, meeting the user's vehicle usage needs and improving the practicality of the suspension system.

[0051] In some embodiments, such as Figure 4 As shown, when the suspension system switches from the standard mode to the second mode, the first region 111-11 is connected to the hydraulic oil power module 120, and the second region 111-12 is connected to the second energy storage component 132, so that the actuating end 111-21 compresses the second region 111-12, and the free end 111-22 drives the buffer block 112 to move to the preset position in the second mode. After the buffer block 112 reaches the preset position, the hydraulic module 111, the hydraulic oil power module 120, and the energy storage component 130 are all turned off.

[0052] Specifically, when the suspension system switches from the standard mode to the second mode, it indicates that the vehicle is traveling on a more distorted road surface, requiring an improvement in the suspension system's anti-rollover capability. Therefore, when the vehicle controller receives the switch from the standard mode to the second mode, it controls the first region 111-11 of the hydraulic cylinder 111-1 to connect with the hydraulic oil power module 120, and the second region 111-12 of the hydraulic cylinder 111-1 to connect with the second energy storage device 132. The hydraulic oil power module 120 is used to input hydraulic oil into the first region 111-11, so that the actuating end 111-21 of the telescopic member 111-2 compresses the second region 111-11. 12. The telescopic member 111-2 extends, and the buffer block 112 retracts, reducing the gap between the buffer blocks to 0. When the buffer block 112 retracts to the preset position corresponding to the second mode, the vehicle controller controls the first region 111-11 to shut off the hydraulic oil power module 120 and the second region 111-12 to shut off the second energy storage device 132. As a result, the position of the working end 111-21 in the hydraulic cylinder 111-1 is fixed, and the gap between the buffer block 112 and the suspension is fixed. Compared with the standard mode, the gap between the buffer blocks is reduced to 0, which helps to improve the stiffness of the suspension system and thus improve the anti-rollover capability of the suspension system.

[0053] It should be noted that in the second mode, the preset position is when the gap between the buffer blocks is 0, and the buffer blocks are in contact with the axle or swing arm of the corresponding suspension.

[0054] In this embodiment, when the buffer block 112 is located at the preset position corresponding to the second module, the buffer block 112 is in contact with the suspension, and the buffer block 112 maintains contact with the suspension to avoid the vehicle from rolling over or the vehicle control performance being reduced due to excessive cornering during driving. This is beneficial to improving the stiffness of the suspension system, thereby improving the vehicle's anti-rollover ability and improving the vehicle's driving safety.

[0055] In some embodiments, such as Figure 5 As shown, the suspension system includes a front suspension 10 and a rear suspension 20, and both the front suspension 10 and the rear suspension 20 are provided with a hydraulic buffer block assembly 110 and an energy storage assembly 130. When the suspension system switches from the standard mode to the third mode, the hydraulic buffer block assembly 110 of the rear suspension 20 is shut off from the energy storage assembly 130 and the hydraulic power module 120. The buffer block 112 is in the standard position. The first region 111-11 of the front suspension 10 is connected to the hydraulic power module 120, and the second region 111-12 is connected to the second energy storage component 132. This causes the actuating end 111-21 to compress the second region 111-12, and the free end 111-22 to move the buffer block 112 to a preset position in the third mode. After the buffer block 112 reaches the preset position, the hydraulic module 111, the hydraulic power module 120, and the energy storage assembly 130 are all shut off.

[0056] Specifically, the vehicle's suspension system includes a front suspension 10 and a rear suspension 20. The front suspension 10 is provided with a left front buffer block 112 and a right front buffer block 112, and the rear suspension 20 is provided with a left rear buffer block 112 and a right rear buffer block 112. Therefore, both the front suspension 10 and the rear suspension 20 are provided with hydraulic buffer block assemblies 110 to adjust the position of each buffer block 112 on the front and rear suspensions respectively. Each hydraulic buffer block assembly 110 is connected to an energy storage assembly 130 so that the energy storage assembly 130 can apply an action to each hydraulic buffer block assembly 110, thereby improving the position adjustment accuracy of the buffer block 112 of the suspension system.

[0057] It should be noted that the hydraulic oil power module 120 can be connected to the first regions 111-11 of the plurality of hydraulic buffer block assemblies 110 and is connected through a solenoid valve 140, so as to determine the hydraulic buffer block assembly 110 operated by the hydraulic oil power module 120 by controlling the on and off of the solenoid valve 140.

[0058] When the suspension system switches from the standard mode to the third mode, it indicates that the user is prioritizing cornering stability. Since cornering is primarily controlled by the front wheels, to improve cornering stability, the position of the buffer block 112 on the front suspension 10 needs to be adjusted so that the buffer block 112 contacts the suspension control arm, i.e., the buffer block clearance is 0. The position of the buffer block 112 on the rear suspension 20 remains in the standard position corresponding to the standard mode. That is, the first area 111-11 of the hydraulic cylinder 111-1 on the front suspension is connected to the hydraulic power module 120, and the second area 111-12 of the hydraulic cylinder 111-1 on the front suspension is connected to the second energy storage device 132, and the hydraulic power module is controlled. Block 120 injects hydraulic oil into the first region 111-11, and then the actuating end 111-21 compresses the second region 111-12, causing the hydraulic oil in the second region 111-12 to flow into the second energy storage unit 132, thereby storing energy in the second energy storage unit 132. When it is determined that the free end 111-22, driven by the actuating end 111-21, moves the buffer block 112 to contact the suspension, the first region 111-11 and the second region 111-12, along with their corresponding hydraulic oil power module 120 and the second energy storage unit 132, are turned off. Consequently, the position of the actuating end 111-21 within the hydraulic cylinder 111-1 is fixed, and the position of the buffer block 112 is fixed.

[0059] In this embodiment, the buffer block 112 of the front suspension 10 is in contact with the suspension, and the front suspension 10 has the greatest stiffness. The gap between the buffer block 112 of the rear suspension 20 and the suspension is in the middle, and the buffer block 112 is located in the standard position. When the vehicle corresponding to the suspension system is turning, the greater stiffness of the front suspension 10 can improve the vehicle's anti-rollover ability and turning stability. The moderate stiffness of the rear suspension 20 has a certain anti-rollover ability and comfort. The suspension system in the third mode can meet the user's needs for improving turning stability and realize the multi-mode adjustment of the suspension system.

[0060] In some embodiments, such as Figure 6As shown, when the suspension system switches from the standard mode to the fourth mode, the hydraulic buffer block assembly 110 of the front suspension 10 is shut off from the energy storage assembly 130 and the hydraulic power module 120, the buffer block 112 is in the standard position, the first region 111-11 of the rear suspension 20 is connected to the hydraulic power module 120, and the second region 111-12 is connected to the second energy storage component 132, so that the actuating end 111-21 compresses the second region 111-12, and the free end 111-22 drives the buffer block 112 to move to the preset position in the third mode. After the buffer block 112 reaches the preset position, the hydraulic module 111, the hydraulic power module 120, and the energy storage assembly 130 are all shut off.

[0061] Specifically, when the suspension system switches from the standard mode to the fourth mode, it indicates that the user is focusing on the vehicle's rapid turning response. Since vehicle turning is mainly controlled by the front wheels, in order to improve the rapid turning response and avoid excessive stiffness of the front suspension 10 affecting the vehicle's turning response, it is necessary to adjust the position of the buffer block 112 on the rear suspension 20 to contact the suspension axle, that is, the gap of the buffer block of the rear suspension 20 is 0, while the position of the buffer block 112 of the front suspension 10 is still in the standard position corresponding to the standard mode.

[0062] Based on this, the hydraulic buffer block assembly 110 of the front suspension 10 is shut off from the energy storage assembly 130 and the hydraulic oil power module 120. The first region 111-11 of the hydraulic buffer block assembly 110 of the rear suspension 20 is connected to the hydraulic oil power module 120, and the second region 111-12 is connected to the second energy storage unit 132. This allows the hydraulic oil power module 120 to inject hydraulic oil into the first region 111-11, and the hydraulic oil in the second region 111-12 to flow into the second energy storage unit 132. The actuating end 111-21 compresses the second region 111-12, and the buffer block 112 moves with the telescopic member 111-2 to contact the axle of the suspension. As a result, the stiffness of the rear suspension 20 is increased, which can improve the anti-rollover ability of the vehicle when turning. At the same time, the stiffness of the front suspension 10 is moderate and has a certain degree of turning maneuverability, which is conducive to improving the vehicle's turning response capability.

[0063] In this embodiment, the buffer block 112 of the front suspension 10 is in the standard position, and the buffer block 112 of the rear suspension 20 is in contact with the suspension, which makes the stiffness of the rear suspension 20 greater. This ensures the vehicle's anti-rollover ability during cornering while improving the vehicle's cornering maneuverability and enhancing the vehicle's rapid cornering response capability.

[0064] In some embodiments, such as Figure 7As shown. When the suspension system switches from the standard mode to the fifth mode, the hydraulic buffer block assembly 110 is disconnected from the hydraulic oil power module 120 and connected to the energy storage assembly 130. The buffer block 112 is used to adaptively adjust its position under the action of the energy storage assembly 130.

[0065] Specifically, the fifth mode is the off-road mode. That is, when the suspension system switches from the standard mode to the fifth mode, it means that the vehicle needs to balance driving comfort and anti-rollover capability during driving. Since the position of the buffer block 112 is fixed, it is impossible to balance driving comfort and anti-rollover capability. Therefore, the position of the buffer block 112 is set to be adaptively adjusted according to the vehicle's driving process.

[0066] Based on this, when the vehicle controller determines that the suspension system has switched to the fifth mode, it shuts off the hydraulic buffer block assembly 110 and the hydraulic oil power module 120. That is, during the fifth mode, the hydraulic oil power module 120 does not apply force to the hydraulic oil buffer block 112 assembly, and connects the buffer block 112 assembly to the energy storage assembly 130. Specifically, the first region 111-11 is connected to the first energy storage component 131, and the second region 111-12 is connected to the second energy storage component 132. When the hydraulic module 111 is subjected to inertial force or other forces during vehicle operation, it drives the actuating end 111-21 to move within the hydraulic cylinder 111-1, thereby realizing the accumulation or release of energy by the first energy storage component 131 and the second energy storage component 132, so that the position of the buffer block 112 can be adaptively adjusted.

[0067] It should be noted that the first energy storage element 131 and the second energy storage element 132 are equivalent to the elastic elements of the first region 111-11 and the second region 111-12, and can elastically adjust the position of the buffer block 112.

[0068] In this embodiment, the energy storage component 130 is connected to the hydraulic cylinder 111-1 buffer block 112 component, and the hydraulic oil power module 120 is disconnected from the hydraulic cylinder 111-1 buffer block 112 component. The position of the action end 111-21 can be adaptively adjusted under the external force on the buffer block 112 and the adaptive adjustment action of the energy storage component 130, thereby realizing the adaptive adjustment of the position of the buffer block 112. This is beneficial to improving the adaptive capability of the suspension system, so as to adapt to the vehicle driving in complex scenarios such as off-road scenarios and improve the vehicle's adaptability.
