Detailed Implementation
[0032] To make the technical problems solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
[0033] like Figure 1 and Figure 2As shown, in one embodiment, the adjustment device 10 includes an adjustment module 1, a drive module 2, and a clamping module 3. The adjustment module 1 includes a first connecting portion 11 and a second connecting portion 12. The first connecting portion 11 has a first connecting area 13 for connecting a first target object, and the second connecting portion 12 has a second connecting area 14 for connecting a second target object. The first connecting portion 11 and the second connecting portion 12 are connected and can generate relative movement in a first direction to increase or decrease the distance between the first connecting area 13 and the second connecting area 14. The drive module 2 is used to provide driving force to make the first connecting portion 11 and the second connecting portion 12 move relative to each other in the first direction. The clamping module 3 is connected to the first connecting portion 11 and can clamp or release the second connecting portion 12. When the clamping module 3 clamps the second connecting portion 12, the first connecting portion 11 and the second connecting portion 12 are relatively fixed. When the clamping module 3 releases the second connecting portion 12, the first connecting portion 11 and the second connecting portion 12 can move relative to each other in the first direction.
[0034] exist Figure 1 Of the directions shown, the first direction is parallel to the Z-axis.
[0035] When the adjustment device 10 is applied to a vehicle, one of the first target object and the second target object can be a shock absorber 20, and the other of the first target object and the second target object can be a suspension. The first direction can be the vertical direction. When the distance between the first connecting area 13 and the second connecting area 14 increases, the height of the shock absorber 20 can be increased, thereby increasing the ground clearance of the vehicle body; when the distance between the first connecting area 13 and the second connecting area 14 decreases, the height of the shock absorber 20 can be decreased, thereby decreasing the ground clearance of the vehicle body.
[0036] In one scenario, the first target object is the shock absorber 20, and the second target object is the suspension.
[0037] Furthermore, when the clamping module 3 clamps the second connecting part 12, the clamping module 3 and the second connecting part 12 are locked together, thus preventing relative movement between the second connecting part 12 and the clamping module 3. Since the clamping module 3 is connected to the first connecting part 11, and the clamping module 3 and the first connecting part 11 cannot move relative to each other, when the clamping module 3 clamps the second connecting part 12, the first connecting part 11 and the second connecting part 12 are locked together, thereby preventing relative movement between the first connecting part 11 and the second connecting part 12 in the first direction.
[0038] During vehicle operation, the clamping module 3 can clamp the second connecting part 12, keeping the first connecting part 11 and the second connecting part 12 fixed, thereby preventing relative movement of the first connecting part 11 and the second connecting part 12 due to ground impact, and thus helping to maintain the vehicle's ground clearance. Moreover, when ground impact causes relative movement of the first connecting part 11 and the second connecting part 12, it can easily cause significant vibration in the vehicle body, leading to a decrease in ride comfort and vehicle safety. The design of this embodiment effectively avoids these problems.
[0039] Furthermore, in this embodiment, by setting up the clamping module 3, the first connecting part 11 and the second connecting part 12 can be kept relatively fixed without the drive module 2 providing driving force. During vehicle operation, the clamping module 3 can clamp the second connecting part 12, keeping the first connecting part 11 and the second connecting part 12 fixed. In this way, after the impact load from the ground is transmitted to the second connecting part 12 through the suspension, the impact of the impact load on the drive module 2 can be avoided or weakened, thereby improving the service life of the drive module 2.
[0040] That is, in this application, when the adjustment device 10 is used to adjust the ground clearance of the vehicle, it can avoid or reduce the impact of ground impact load on the drive module 2, thereby improving the service life of the drive module 2.
[0041] Additionally, it should be noted that the connection of the clamping module 3 to the first connecting part 11 can mean that the clamping module 3 is directly connected to the first connecting part 11. In this case, the clamping module 3 and the first connecting part 11 are directly connected, and the clamping module 3 and the first connecting part 11 can be fixed together by bolts or other connecting parts; or, the connection of the clamping module 3 to the first connecting part 11 can also mean that both the clamping module 3 and the first connecting part 11 are connected to the corresponding supporting object. In this case, the clamping module 3 and the first connecting part 11 are indirectly connected.
[0042] Furthermore, in the first direction, when the first connecting part 11 and the second connecting part 12 move relative to each other to any position, the clamping module 3 can clamp or release the second connecting part 12.
[0043] like Figure 2As shown, in one embodiment, the first connecting portion 11 includes a first cylinder 111, which has a first chamber 112; the second connecting portion 12 includes a first piston 121 and a first piston rod 122; the first piston 121 is installed in the first chamber 112 and can move relative to the first cylinder 111 along a first direction; one end of the first piston rod 122 is located in the first chamber 112 and connected to the first piston 121, and the other end of the first piston rod 122 is located outside the first cylinder 111; a first connecting area 13 is located on the first cylinder 111; a second connecting area 14 is located on the first piston rod 122 and outside the first cylinder 111. The axis of the first piston rod 122 and the axis of the first cylinder 111 are both parallel to the first direction.
[0044] During operation, the clamping module 3 can clamp the first piston rod 122, thereby keeping the first piston rod 122 and the first cylinder 111 relatively fixed and preventing relative displacement between them in the first direction. Since the radial dimension of the first cylinder 111 is larger than that of the first piston rod 122, connecting the clamping module 3 to the first cylinder 111 makes assembly easier.
[0045] It should be understood that, in this embodiment, the drive module 2 is used to introduce fluid into the first chamber 112 so as to drive the first connecting part 11 and the second connecting part 12 to move relative to each other in a first direction.
[0046] In one embodiment, the adjustment module 1 is a hydraulic cylinder. In this case, the drive module 2 is a hydraulic system used to introduce liquid into the first chamber 112, thereby driving the first piston rod 122 and the first cylinder 111 to generate relative movement in the first direction. This arrangement allows the drive module 2 to provide greater driving force.
[0047] In this embodiment, the clamping action of the clamping module 3 on the first piston rod 122 can avoid or reduce the impact of ground impact load on the hydraulic system, thereby effectively avoiding damage to the pipeline seals and other related hydraulic components of the hydraulic system.
[0048] like Figure 2 As shown, in one embodiment, the first cylinder 111 has a first surface 113 and a second surface 114 disposed opposite to each other, and the first chamber 112 is a cavity structure with one end open, wherein the first chamber 112 forms an opening on the first surface 113, and the first piston rod 122 extends out of the first cylinder 111 from the first surface 113.
[0049] like Figure 2 As shown, in one embodiment, a first connection area 13 is disposed on a second surface 114, wherein the first connection area 13 may be a threaded hole disposed on the second surface 114, which may engage with a stud thread on a first target object.
[0050] like Figure 2 As shown, in one embodiment, the second connecting area 14 is disposed at the end of the piston rod opposite to the second surface 114, wherein the second connecting area 14 may be a lifting ring. In this case, the second connecting area 14 may be connected to the second target object by means of a bolt or other connecting component.
[0051] like Figure 1 As shown, in one embodiment, the clamping module 3 is located outside the first cylinder 111 and can clamp or release the first piston rod 122 outside the first cylinder 111. This arrangement is more conducive to the design and assembly of the adjustment device 10.
[0052] like Figure 2 As shown, in one embodiment, the adjustment module 1 further includes a first elastic member 15, which can apply force to at least one of the first connecting portion 11 and the second connecting portion 12, so that the first connecting area 13 and the second connecting area 14 are moved away from each other.
[0053] When the first connection area 13 connects to the shock absorber 20 and the second connection area 14 connects to the suspension, the first connection area 13 and the second connection area 14 move away from each other. In reality, the second connection area 14 remains stationary, while the first connection area 13 moves away from the second connection area 14, causing the shock absorber 20 and the vehicle body to be raised. During this process, the hydraulic system needs to provide a large pressure, but the setting of the first elastic element 15 can reduce the pressure of the hydraulic system and reduce the cost of the hydraulic system.
[0054] like Figure 2 As shown, in one embodiment, the first elastic member 15 is disposed in the first chamber 112 and is capable of elastic deformation in a first direction; the first elastic member 15 is capable of applying force to the first connecting portion 11 and the second connecting portion 12, so that the first connecting area 13 and the second connecting area 14 are moved away from each other.
[0055] like Figure 2 As shown, in one embodiment, the first elastic member 15 may be compressed within the first chamber 112, and the end of the first piston 121 rod away from the first elastic member 15 may extend out of the first cylinder 111. In this way, the first elastic member 15 can continuously provide a driving force that keeps the first connecting region 13 and the second connecting region 14 away from each other.
[0056] In one embodiment, one end of the first elastic element 15 abuts against the first piston rod 122, and the other end of the first elastic element 15 abuts against the bottom surface of the first chamber 112. Alternatively, the first elastic element 15 may be a coil spring.
[0057] like Figure 2As shown, in one embodiment, in a first direction, the first cylinder 111 has a first end and a second end disposed opposite to each other; the rod of the first piston 121 extends out of the first cylinder 111 from the first end; the first elastic member 15 is located between the second end and the first piston 121; the second end is provided with a first through hole 16, which extends from the outer surface of the first cylinder 111 to communicate with the first chamber 112; the drive module 2 can introduce fluid into the first chamber 112 through the first through hole 16, and the fluid in the first chamber 112 can be discharged from the first cylinder 111 through the first through hole 16.
[0058] The end face of the first end is the first surface 113, and the end face of the second end is the second surface 114.
[0059] like Figure 2 As shown, in one embodiment, the first perforation 16 may be provided on the outer surface of the first cylinder 111 and extend through to the bottom surface of the first chamber 112. In the first direction, the two ends of the outer surface of the first cylinder 111 intersect at the first surface 113 and the second surface 114, respectively. In this case, the first perforation 16 forms an opening on both the outer surface of the first cylinder 111 and the bottom surface of the first chamber 112.
[0060] like Figure 1 As shown, in one embodiment, the drive module 2 includes a liquid storage tank 21, a hydraulic pump 22, and a first control valve 23; the inlet of the hydraulic pump 22 is connected to the liquid storage tank 21, the outlet of the hydraulic pump 22 is connected to the inlet of the first control valve 23, and the outlet of the first control valve 23 is connected to the first chamber 112; the first control valve 23 is used to control the connection and disconnection between the outlet of the hydraulic pump 22 and the first chamber 112.
[0061] In addition, the inlet of the hydraulic pump 22 is connected to the storage tank 21 by a first pipe 241, the outlet of the hydraulic pump 22 is connected to the inlet of the first control valve 23 by a second pipe 242, and the outlet of the first control valve 23 is connected to the first chamber 112 by a third pipe 243.
[0062] When the outlet of hydraulic pump 22 is connected to the first chamber 112, if hydraulic pump 22 is working, the liquid in reservoir 21 can enter hydraulic pump 22 from the inlet and flow out from the outlet. Subsequently, the liquid flowing out from the outlet of hydraulic pump 22 will enter the first control valve 23 from the inlet and flow out from the outlet of the first control valve 23 into the first chamber 112. The liquid entering the first chamber 112 actually enters the space between the first piston 121 and the bottom surface of the first chamber 112, which can be called the rodless chamber. If the clamping module 3 releases the first piston 121 rod, the first cylinder 111 can move upwards by introducing liquid into the rodless chamber, thereby increasing the height of the shock absorber 20 and the vehicle.
[0063] When the outlet of the hydraulic pump 22 is disconnected from the first chamber 112, the liquid flowing out of the outlet of the hydraulic pump 22 cannot enter the first chamber 112.
[0064] In one embodiment, the first control valve 23 may be a two-position two-way solenoid directional valve, etc.
[0065] like Figure 1 As shown, in one embodiment, the drive module 2 further includes a second control valve 25 and a third control valve 26; the second control valve 25 is disposed between the first control valve 23 and the hydraulic pump 22, the inlet of the second control valve 25 is connected to the outlet of the hydraulic pump 22, and the outlet of the second control valve 25 is connected to the inlet of the first control valve 23; the inlet of the third control valve 26 is connected between the inlet of the first control valve 23 and the outlet of the second control valve 25, and the outlet of the third control valve 26 is connected to the storage tank 21; the second control valve 25 is used to control the connection and disconnection between the outlet of the hydraulic pump 22 and the inlet of the first control valve 23; the third control valve 26 is used to control the connection and disconnection between the inlet of the first control valve 23 and the storage tank 21.
[0066] This configuration allows the liquid in the first chamber 112 (rodless chamber) to flow back into the storage tank 21, and during this process, the liquid flowing out of the first chamber 112 does not need to pass through the hydraulic pump 22.
[0067] In a real-world scenario, when it is necessary to lower the vehicle's ground clearance, the hydraulic pump 22's outlet can be connected to the first chamber 112 via the first control valve 23, and the clamping module 3 can be controlled to release the first piston 121 rod. Under the weight of the vehicle, the first cylinder 111 can be driven to move downwards. At this time, the liquid in the first chamber 112 will be discharged from the first perforation 16.
[0068] like Figure 1As shown, in one embodiment, the second control valve 25 is a check valve; the direction from the outlet of the hydraulic pump 22 to the inlet of the first control valve 23 is the conduction direction of the check valve; the direction from the inlet of the first control valve 23 to the outlet of the hydraulic pump 22 is the shut-off direction of the check valve. That is, the liquid flowing out of the outlet of the hydraulic pump 22 can open the check valve and flow to the inlet of the first control valve 23; while the liquid flowing out of the inlet of the first control valve 23 cannot open the check valve and therefore cannot flow to the outlet of the hydraulic pump 22.
[0069] In addition, the check valve can be an existing design, which will not be described in detail in this embodiment.
[0070] like Figure 1 As shown, the second pipe 242 includes a first pipe section 244 and a second pipe section 245. The first pipe section 244 is located between the hydraulic pump 22 and the second control valve 25, and its two ends are respectively connected to the outlet of the hydraulic pump 22 and the inlet of the second control valve 25. The second pipe section 245 is located between the second control valve 25 and the first control valve 23, and its two ends are respectively connected to the outlet of the second control valve 25 and the inlet of the first control valve 23.
[0071] like Figure 1 As shown, in one embodiment, the third control valve 26 is a reflux valve; the reflux valve also includes a control port, which is connected between the inlet of the second control valve 25 and the outlet of the hydraulic pump 22; the liquid flowing out of the outlet of the hydraulic pump 22 can enter the third control valve 26 through the control port, thereby shutting off the inlet and outlet of the third control valve 26. The reflux valve can be a conventional design, which will not be described in detail in this embodiment.
[0072] When liquid is introduced into the first chamber 112, the hydraulic pump 22 operates. At this time, the return valve is closed, and the liquid flowing out from the outlet of the second control valve 25 will not flow back to the storage tank 21 from the third control valve 26.
[0073] When the liquid in the first chamber 112 is discharged, the hydraulic pump 22 does not work. At this time, the inlet and outlet of the return valve are connected, so that the liquid discharged from the first chamber 112 can flow from the third control valve 26 to the storage tank 21 after passing through the first control valve 23.
[0074] In addition, the inlet of the third control valve 26 can be connected to the second section pipe 245 through the fourth pipe 246, thereby connecting the inlet of the third control valve 26 to the inlet of the first control valve 23 and the outlet of the second control valve 25; the outlet of the third control valve 26 can be connected to the storage tank 21 through the fifth pipe 247; the control port of the reflux valve can be connected to the first section pipe 244 through the sixth pipe 248, thereby connecting the control port to the inlet of the second control valve 25 and the outlet of the hydraulic pump 22.
[0075] like Figure 1 As shown, in one embodiment, the clamping module 3 is a gripper hydraulic cylinder; the drive module 2 is used to drive the clamping module 3 to move, enabling the clamping module 3 to clamp or release the second connecting part 12; the drive module 2 also includes a fourth control valve 27; the inlet of the fourth control valve 27 is connected between the inlet of the first control valve 23 and the inlet of the third control valve 26, and the outlet of the fourth control valve 27 is connected to the clamping module 3; the third control valve 26 is used to control the connection and disconnection between the clamping module 3 and the outlet of the second control valve 25. This arrangement allows the operation of the adjustment module 1 and the clamping module 3 to be driven by a single hydraulic system, reducing the number of power systems, thereby reducing the cost of the adjustment device 10 and facilitating the production and use of the adjustment device 10.
[0076] The inlet of the fourth control valve 27 is connected to the second section pipe 245 via the seventh pipe 249, thereby connecting the inlet of the fourth control valve 27 between the inlet of the first control valve 23 and the inlet of the third control valve 26. Furthermore, the outlet of the fourth control valve 27 is connected to the clamping module 3 via the eighth pipe 250. Additionally, the fourth control valve 27 can be a two-position two-way solenoid directional valve, etc.
[0077] like Figure 1 and Figure 3 As shown, in one embodiment, the clamping module 3 includes a clamping drive unit 31 and two clamping blocks 32. The clamping drive unit 31 is used to drive the two clamping blocks 32 to move towards each other or away from each other along a second direction. When the two clamping blocks 32 move towards each other, they can clamp the second connecting part 12. When the two clamping blocks 32 move away from each other, they can release the second connecting part 12. The angle between the second direction and the first direction is greater than 0 degrees and less than 180 degrees.
[0078] Preferably, the first direction and the second direction are perpendicular to each other. Figure 1 Of the directions shown, the second direction is parallel to the X-axis.
[0079] like Figure 3As shown, in one embodiment, the clamping drive unit 31 includes a second cylinder 311, a second piston 312, and a second piston rod 313; the second cylinder 311 has a second chamber 314, the second piston 312 is installed in the second chamber 314, one end of the second piston rod 313 is located in the second chamber 314 and connected to the second piston 312, and the other end of the second piston rod 313 is located outside the second cylinder 311 for driving the clamping block 32.
[0080] It should be understood that the clamping drive unit 31 also includes a corresponding transmission mechanism 33 (see reference). Figure 4 This allows the driving force of the second piston rod 313 to be simultaneously transmitted to the two clamping blocks 32 via the transmission mechanism 33.
[0081] In addition, the second cylinder 311 can be fixed on the first cylinder 111. The fact that the second cylinder 311 and the first cylinder 111 cannot move relative to each other means that the clamping module 3 and the first connecting part 11 cannot move relative to each other.
[0082] like Figure 4 As shown, in one feasible embodiment, the transmission mechanism 33 includes a first rack 331, a second rack 332, a third rack 333, a first gear 334, and a second gear 335; wherein, the first rack 331 is connected to the second piston rod 313, and the first rack 331 meshes with the first gear 334; the second gear 335 is coaxially arranged with the first gear 334, and the two can be fixed together; the second rack 332 and the third rack 333 are parallel and spaced apart on both sides of the second gear 335, and both the second rack 332 and the third rack 333 mesh with the second gear 335; the two clamping blocks 32 are respectively the first clamping block and the second clamping block, the first clamping block is connected to the second rack 332, and the second clamping block is connected to the third rack 333, and the first clamping block and the second clamping block are respectively located on opposite sides of the second gear 335.
[0083] exist Figure 4 In the indicated direction, when the second piston rod 313 extends, it drives the first rack 331 to move linearly. At this time, the first rack 331 drives the first gear 334 to rotate clockwise, and the second gear 335 also rotates clockwise. This causes the second rack 332 and the third rack 333 to move linearly in the second direction, and the second rack 332 and the third rack 333 move in opposite directions. This allows the two clamping blocks 32 to approach each other and clamp the second connecting part 12. When the second piston rod 313 retracts, it drives the two clamping blocks 32 to move away from each other, thereby releasing the second connecting part 12.
[0084] The second piston rod 313 can drive the first rack 331 to move linearly along the second direction. The second rack 332 and the third rack 333 are spaced apart along a third direction, which is perpendicular to the second direction and also perpendicular to the first direction. The axis of the first gear 334 is parallel to the first direction. Figure 4 Of the directions shown, the third direction is parallel to the Y-axis.
[0085] Of course, the transmission mechanism 33 can also adopt other existing designs, which will not be described in detail in this embodiment. In addition, the design of the gripper hydraulic cylinder can also adopt existing technology, which will not be described in detail in this embodiment.
[0086] like Figure 3 As shown, in one embodiment, the clamping drive unit 31 further includes a second elastic element 34, which is located within the second chamber 314 and compressed between the second cylinder 311 and the second piston rod 313. This allows the second piston rod 313, under the elastic force of the second elastic element 34, to press the clamping block 32 against the second connecting portion 12. Thus, even when the hydraulic system is not operating, the pressure of the second elastic element 34 can still cause the two clamping blocks 32 to clamp the second connecting portion 12.
[0087] In addition, the end of the second piston rod 313 away from the second elastic member 34 extends out of the second cylinder 311. Specifically, the second piston 312 and the second piston rod 313 divide the second chamber 314 into a rod chamber and a rodless chamber, wherein the second elastic member 34 is disposed in the rodless chamber of the second chamber 314.
[0088] like Figure 3 As shown, the second cylinder 311 is provided with a second through hole 315, which extends from the outer surface of the second cylinder 311 to communicate with the second chamber 314. External fluid can enter the second chamber 314 through the second through hole 315, and fluid inside the second chamber 314 can also exit the second chamber 314 through the second through hole 315. In addition, the second through hole 315 communicates with the rod chamber of the second chamber 314.
[0089] In one embodiment, the adjustment device 10 further includes a controller for controlling the operation of components such as the drive module 2 and the clamping module 3. When the adjustment device 10 is applied in scenarios such as vehicles, the adjustment device 10 itself may not have a controller. In this case, the operation of the corresponding components in the adjustment device 10 can be controlled by the control device built into the vehicle.

[0093] In other embodiments, the second connecting region 14 may also be located at other positions on the first piston rod 122, such as on the side of the first piston rod 122. Furthermore, the first connecting region 13 and the second target object can be connected by welding or other methods.
[0094] In other embodiments, when the second connecting portion 12 includes the first piston 121, it may not include the first piston rod 122; in this case, the clamping module 3 may directly clamp or release the first piston 121. Additionally, in this embodiment, if the first chamber 112 is provided with a first elastic member 15, when the first piston 121 moves relative to the first cylinder 111 in the first direction, the first piston 121 can apply force to the first elastic member 15, causing the first elastic member 15 to elastically deform in the first direction.
[0095] In other embodiments, the first elastic member 15 may also be disposed outside the first chamber 112. In this case, the first elastic member 15 may also be compressed between the first connecting portion 11 and the second connecting portion 12.
[0096] In other embodiments, the first elastic member 15 may apply force only to the first connecting portion 11 or only to the second connecting portion 12.
[0097] In other embodiments, the first perforation 16 may also be disposed on the second surface 114, in which case the first perforation 16 forms an opening on the second surface 114. Of course, in other embodiments, the first perforation 16 may also extend to the inner side of the first chamber 112, in which case the first perforation 16 forms an opening on the inner side of the first chamber 112.
[0098] In other embodiments, the second control valve 25 may also be a directional control valve, such as a two-position two-way solenoid directional control valve.
[0099] In other embodiments, the third control valve 26 may also be a directional control valve, such as a two-position two-way solenoid directional control valve.

[0101] In other embodiments, the clamping drive unit 31 may also directly drive the second gear 335 to rotate. In this case, the clamping drive unit 31 may be a rotary hydraulic cylinder or a rotary motor, etc.
[0102] In other embodiments, the drive module 2 may also drive the first connecting part 11 and the second connecting part 12 to move relative to each other in a first direction via electric drive. In this case, the drive module 2 may be an electric cylinder or the like. Alternatively, the drive module 2 may be a pneumatic system or the like.
[0103] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
