[0040] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0041] like Figure 1 and Figure 2As shown, in one embodiment, the adjustment device 10 includes an adjustment module 1, a driving module 2 and a clamping module 3; the adjustment module 1 includes a first connection part 11 and a second connection part 12, the first connection part 11 has a first connection area 13 for connecting to a first target object, and the second connection part 12 has a second connection area 14 for connecting to a second target object; the first connection part 11 and the second connection part 12 are connected and can generate relative movement in a first direction to increase or decrease the distance between the first connection area 13 and the second connection area 14; the driving module 2 is used to provide a driving force to enable the first connection part 11 and the second connection part 12 to move relative to each other in the first direction; the clamping module 3 is connected to the first connection part 11 and can clamp or release the second connection part 12; when the clamping module 3 clamps the second connection part 12, the first connection part 11 and the second connection part 12 are relatively fixed; when the clamping module 3 releases the second connection part 12, the first connection part 11 and the second connection part 12 can move relative to each other in the first direction.

[0042] exist Figure 1 In the directions shown, the first direction is parallel to the Z axis.

[0043] When the adjustment device 10 is applied to a vehicle, one of the first target object and the second target object may be a shock absorber 20, the other of the first target object and the second target object may be a suspension, and the first direction may be a vertical direction. When the distance between the first connection area 13 and the second connection area 14 increases, the height of the shock absorber 20 can be increased, thereby increasing the height of the vehicle body from the ground; when the distance between the first connection area 13 and the second connection area 14 decreases, the height of the shock absorber 20 can be reduced, thereby reducing the height of the vehicle body from the ground.

[0044] In one scenario, the first target object is the shock absorber 20 and the second target object is the suspension.

[0045] In addition, when the clamping module 3 clamps the second connection part 12, the clamping module 3 and the second connection part 12 are locked together, thereby preventing the second connection part 12 and the clamping module 3 from making relative movement. Since the clamping module 3 is connected to the first connection part 11, the clamping module 3 and the first connection part 11 cannot make relative movement. Therefore, when the clamping module 3 clamps the second connection part 12, the first connection part 11 and the second connection part 12 are locked together, thereby preventing the first connection part 11 and the second connection part 12 from making relative movement in the first direction.

[0046] During the driving process of the vehicle, the holding module 3 can hold the second connection part 12 tightly, so that the first connection part 11 and the second connection part 12 remain fixed, thereby avoiding the relative movement of the first connection part 11 and the second connection part 12 due to ground impact, which is conducive to maintaining the height of the vehicle body from the ground. In addition, when the first connection part 11 and the second connection part 12 move relative to each other due to ground impact, it is easy to cause the vehicle body to vibrate greatly, thereby causing a decrease in riding comfort and vehicle safety. Through the configuration of this embodiment, these problems can be effectively avoided.

[0047] In addition, in this embodiment, by setting the clamping module 3, it is possible to keep the first connection part 11 and the second connection part 12 relatively fixed without the need for the driving module 2 to provide driving force. During the driving process of the vehicle, the clamping module 3 can clamp the second connection part 12 to keep the first connection part 11 and the second connection part 12 fixed, so that after the impact load of the ground is transmitted to the second connection part 12 through the suspension, the impact of the impact load on the driving module 2 can be avoided or weakened, thereby increasing the service life of the driving module 2.

[0048] That is, in the present application, when the adjusting device 10 is used to adjust the height of the vehicle from the ground, the impact of the ground impact load on the driving module 2 can be avoided or weakened, thereby increasing the service life of the driving module 2.

[0049] In addition, it should be explained that the clamping module 3 is connected to the first connecting part 11, which may 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 at this time, the clamping module 3 and the first connecting part 11 may be fixed together by bolts and other connecting parts; or, the clamping module 3 is connected to the first connecting part 11, which may mean that the clamping module 3 and the first connecting part 11 are both connected to corresponding supporting objects. In this case, the clamping module 3 and the first connecting part 11 are indirectly connected.

[0050] In addition, in the first direction, when the first connecting portion 11 and the second connecting portion 12 move relative to each other to any position, the clamping module 3 can clamp or release the second connecting portion 12 .

[0051] like Figure 2As shown, in one embodiment, the first connecting part 11 includes a first cylinder 111, and the first cylinder 111 has a first chamber 112; the second connecting part 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 the 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; the first connecting area 13 is located on the first cylinder 111; the second connecting area 14 is located on the first piston rod 122 and outside the first cylinder 111. Among them, the axis of the first piston rod 122 and the axis of the first cylinder 111 are both parallel to the first direction.

[0052] When working, the clamping module 3 can clamp the first piston rod 122, thereby keeping the first piston rod 122 relatively fixed with the first cylinder body 111, and preventing the two from having relative displacement in the first direction. Since the radial dimension of the first cylinder body 111 is larger than the radial dimension of the first piston rod 122, connecting the clamping module 3 to the first cylinder body 111 can facilitate assembly.

[0053] It should be understood that, in this embodiment, the driving module 2 is used to introduce fluid into the first chamber 112 so as to drive the first connecting portion 11 and the second connecting portion 12 to move relative to each other in the first direction.

[0054] In one embodiment, the adjustment module 1 is a hydraulic cylinder. In this case, the drive module 2 is a hydraulic system for introducing liquid into the first chamber 112, thereby driving the first piston rod 122 and the first cylinder body 111 to produce relative movement in the first direction. This arrangement enables the drive module 2 to provide greater driving force.

[0055] In this embodiment, the clamping effect of the clamping module 3 on the first piston rod 122 can avoid or reduce the impact of the ground impact load on the hydraulic system, thereby effectively avoiding damage to the pipeline seal and other related hydraulic components of the hydraulic system.

[0056] like Figure 2 As shown, in one embodiment, the first cylinder body 111 has a first surface 113 and a second surface 114 arranged opposite to each other, and the first chamber 112 is a cavity structure with an opening at one end, 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 body 111 from the first surface 113.

[0057] like Figure 2 As shown, in one embodiment, the first connection area 13 is disposed on the second surface 114, wherein the first connection area 13 may be a threaded hole disposed on the second surface 114, and the threaded hole may be threadably matched with a stud on the first target object.

[0058] like Figure 2 As shown, in one embodiment, the second connection area 14 is arranged at the end of the piston rod away from the second surface 114, wherein the second connection area 14 may be a lifting ring. In this case, the second connection area 14 may be connected to the second target object by a connecting member such as a bolt.

[0059] like Figure 1 As shown, in one embodiment, the clamping module 3 is located outside the first cylinder body 111 and can clamp or loosen the first piston rod 122 outside the first cylinder body 111 . Such a configuration is more conducive to the design and assembly of the adjusting device 10 .

[0060] like Figure 2 As shown, in one embodiment, the adjustment module 1 further includes a first elastic member 15, and the first elastic member 15 can apply force to at least one of the first connection portion 11 and the second connection portion 12 to move the first connection area 13 and the second connection area 14 away from each other.

[0061] When the first connection area 13 is connected to the shock absorber 20 and the second connection area 14 is connected to the suspension, the first connection area 13 and the second connection area 14 are separated from each other. In fact, the second connection area 14 is stationary, and the first connection area 13 is separated from the second connection area 14, so that the shock absorber 20 and the vehicle body are lifted. In this process, the hydraulic system needs to provide a large pressure, and the first elastic member 15 can reduce the pressure of the hydraulic system and reduce the cost of the hydraulic system.

[0062] like Figure 2 As shown, in one embodiment, the first elastic member 15 is disposed in the first chamber 112 and can be elastically deformed in a first direction; the first elastic member 15 can apply force to the first connecting portion 11 and the second connecting portion 12 to move the first connecting area 13 and the second connecting area 14 away from each other.

[0063] like Figure 2 As shown, in one embodiment, the first elastic member 15 can be compressed in the first chamber 112, and the end of the first piston 121 away from the first elastic member 15 extends out of the first cylinder body 111. In this way, the first elastic member 15 can continuously provide a driving force to move the first connection area 13 and the second connection area 14 away from each other.

[0064] In one embodiment, one end of the first elastic member 15 abuts against the first piston rod 122, and the other end of the first elastic member 15 abuts against the bottom surface of the first chamber 112. In addition, the first elastic member 15 may be a coil spring.

[0065] like Figure 2As shown, in one embodiment, in a first direction, the first cylinder body 111 has a first end and a second end arranged opposite to each other; the first piston 121 rod extends from the first end of the first cylinder body 111; 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, and the first through hole 16 extends from the outer surface of the first cylinder body 111 to connect to the first chamber 112; the driving module 2 can pass fluid into the first chamber 112 from the first through hole 16, and the fluid in the first chamber 112 can be discharged from the first through hole 16 to the first cylinder body 111.

[0066] The end surface of the first end is the first surface 113 , and the end surface of the second end is the second surface 114 .

[0067] like Figure 2 As shown, in one embodiment, the first through hole 16 may be disposed on the outer side of the first cylinder 111 and extend through the bottom surface of the first chamber 112. In the first direction, the two ends of the outer side of the first cylinder 111 intersect the first surface 113 and the second surface 114 respectively. At this time, the first through hole 16 forms an opening on both the outer side of the first cylinder 111 and the bottom surface of the first chamber 112.

[0068] like Figure 1 As shown, in one embodiment, the driving module 2 includes a liquid storage tank 21, a hydraulic pump 22 and a first control valve 23; the liquid inlet of the hydraulic pump 22 is connected to the liquid storage tank 21, the liquid outlet of the hydraulic pump 22 is connected to the liquid inlet of the first control valve 23, and the liquid outlet of the first control valve 23 is connected to the first chamber 112; the first control valve 23 is used to control the conduction and disconnection between the liquid outlet of the hydraulic pump 22 and the first chamber 112.

[0069] In addition, the liquid inlet of the hydraulic pump 22 and the liquid storage tank 21 can be connected through a first pipe 241, the liquid outlet of the hydraulic pump 22 and the liquid inlet of the first control valve 23 can be connected through a second pipe 242, and the liquid outlet of the first control valve 23 and the first chamber 112 can be connected through a third pipe 243.

[0070] When the liquid outlet of the hydraulic pump 22 is connected to the first chamber 112, if the hydraulic pump 22 is working, the liquid in the liquid storage tank 21 can enter the hydraulic pump 22 from the liquid inlet of the hydraulic pump 22, and flow out from the liquid outlet of the hydraulic pump 22. Subsequently, the liquid flowing out from the liquid outlet of the hydraulic pump 22 will enter the first control valve 23 from the liquid inlet of the first control valve 23, and enter the first chamber 112 from the liquid outlet of the first control valve 23. Among them, the liquid passed into the first chamber 112 is actually passed into the space between the first piston 121 and the bottom surface of the first chamber 112, which can be called a rodless chamber. At this time, if the clamping module 3 releases the rod of the first piston 121, the first cylinder body 111 can be moved upward by passing liquid into the rodless chamber, thereby increasing the height of the shock absorber 20 and the vehicle.

[0071] When the liquid outlet of the hydraulic pump 22 is disconnected from the first chamber 112 , the liquid flowing out of the liquid outlet of the hydraulic pump 22 cannot enter the first chamber 112 .

[0072] In one embodiment, the first control valve 23 may be a two-position two-way electromagnetic reversing valve or the like.

[0073] like Figure 1 As shown, in one embodiment, the drive module 2 also includes a second control valve 25 and a third control valve 26; the second control valve 25 is arranged between the first control valve 23 and the hydraulic pump 22, the liquid inlet of the second control valve 25 is connected to the liquid outlet of the hydraulic pump 22, and the liquid outlet of the second control valve 25 is connected to the liquid inlet of the first control valve 23; the liquid inlet of the third control valve 26 is connected between the liquid inlet of the first control valve 23 and the liquid outlet of the second control valve 25, and the liquid outlet of the third control valve 26 is connected to the liquid storage tank 21; the second control valve 25 is used to control the conduction and disconnection of the liquid outlet of the hydraulic pump 22 and the liquid inlet of the first control valve 23; the third control valve 26 is used to control the conduction and disconnection of the liquid inlet of the first control valve 23 and the liquid storage tank 21.

[0074] Such an arrangement can enable the liquid in the first chamber 112 (rodless chamber) to flow back into the liquid storage tank 21 , and in this process, the liquid flowing out of the first chamber 112 does not need to pass through the hydraulic pump 22 .

[0075] In actual scenarios, when the height of the vehicle body needs to be lowered from the ground, the first control valve 23 can be used to connect the outlet of the hydraulic pump 22 to the first chamber 112, and the clamping module 3 can be controlled to release the first piston 121 rod. In this way, under the action of the gravity of the vehicle body, the first cylinder body 111 can be driven to move downward. At this time, the liquid in the first chamber 112 will be discharged from the first chamber 112 through the first perforation 16.

[0076] like Figure 1As shown, in one embodiment, the second control valve 25 is a one-way valve; the direction from the outlet of the hydraulic pump 22 to the inlet of the first control valve 23 is the conducting direction of the one-way valve; the direction from the inlet of the first control valve 23 to the outlet of the hydraulic pump 22 is the closing direction of the one-way valve. That is, the liquid flowing out of the outlet of the hydraulic pump 22 can make the one-way valve conduct, and then 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 make the one-way valve conduct, and then cannot flow to the outlet of the hydraulic pump 22.

[0077] In addition, the one-way valve may adopt an existing design, which will not be described in detail in this embodiment.

[0078] like Figure 1 As shown, the second pipeline 242 includes a first section of pipe 244 and a second section of pipe 245, wherein the first section of pipe 244 is located between the hydraulic pump 22 and the second control valve 25, and the two ends of the first section of pipe 244 are respectively connected to the liquid outlet of the hydraulic pump 22 and the liquid inlet of the second control valve 25; the second section of pipe 245 is located between the second control valve 25 and the first control valve 23, and the two ends of the second section of pipe 245 are respectively connected to the liquid outlet of the second control valve 25 and the liquid inlet of the first control valve 23.

[0079] 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 liquid inlet of the second control valve 25 and the liquid outlet of the hydraulic pump 22; the liquid flowing out of the liquid outlet of the hydraulic pump 22 can enter the third control valve 26 from the control port, so that the liquid inlet of the third control valve 26 and the liquid outlet of the third control valve 26 are cut off. Among them, the reflux valve can be an existing design, and this embodiment will not be described in detail here.

[0080] When liquid is input into the first chamber 112 , the hydraulic pump 22 works. At this time, the reflux valve is closed, and the liquid flowing out of the liquid outlet of the second control valve 25 will not flow back to the liquid storage tank 21 through the third control valve 26 .

[0081] When the liquid in the first chamber 112 is discharged, the hydraulic pump 22 does not work. At this time, the liquid inlet and the liquid outlet of the reflux valve are connected, so that the liquid discharged from the first chamber 112 can flow from the third control valve 26 to the liquid storage tank 21 after passing through the first control valve 23.

[0082] In addition, the liquid inlet of the third control valve 26 can be connected to the second section of the pipe 245 through the fourth pipe 246, so that the liquid inlet of the third control valve 26 is connected between the liquid inlet of the first control valve 23 and the liquid outlet of the second control valve 25; the liquid outlet of the third control valve 26 can be connected to the liquid storage tank 21 through the fifth pipe 247; the control port of the reflux valve can be connected to the first section of the pipe 244 through the sixth pipe 248, so that the control port is connected between the liquid inlet of the second control valve 25 and the liquid outlet of the hydraulic pump 22.

[0086] Preferably, the first direction and the second direction are perpendicular to each other. Figure 1 In the directions shown, the second direction is parallel to the X-axis.

[0089] In addition, the second cylinder 311 may be fixed on the first cylinder 111 . The second cylinder 311 and the first cylinder 111 cannot move relative to each other, which means that the clamping module 3 and the first connecting portion 11 cannot move relative to each other.

When the second piston rod 313 is retracted, the two clamping blocks 32 can be driven to move away from each other, thereby releasing the second connecting part 12.

In this way, when the hydraulic system is not working, the pressure of the second elastic member 34 can also enable the two clamping blocks 32 to clamp the second connecting portion 12.

[0095] In addition, one end of the second piston rod 313 away from the second elastic member 34 extends out of the second cylinder body 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 arranged in the rodless chamber of the second chamber 314 .

[0096] like Figure 3 As shown, the second cylinder body 311 is provided with a second through hole 315, and the second through hole 315 penetrates from the outer surface of the second cylinder body 311 to communicate with the second chamber 314.
