There is a problem that the support structure cannot effectively buffer the impact force, which affects the NVH (Noise, Vibration, Harshness) performance and handling stability of the entire vehicle. Utility Model Content

[0004] In view of this, the present application aims to propose a shock absorber assembly which has a good vibration buffering effect and can reduce the impact on the vehicle body.

[0005] To achieve the above purpose, the technical solution of this application is implemented as follows:

[0009] In some embodiments of the present application, the base of the hydraulic cylinder is provided with a liquid injection port, and the shock absorber assembly further includes a liquid injection seat, the liquid injection seat is formed with a liquid injection cavity, the liquid injection seat is sleeved on the base, and the liquid injection cavity is connected to the liquid injection port.

[0010] In some embodiments of the present application, the shock absorber assembly further includes a gasket, which is sleeved on the base and sandwiched between the liquid filling seat and the second shock absorbing part.

[0011] In some embodiments of the present application, the shock absorber assembly also includes a threaded connector, a threaded section is provided at the end of the base, the threaded section passes through the liquid filling seat, and the threaded section is threadedly matched with the threaded connector to fix the liquid filling seat to the base.

[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0034] The following will refer to the attached Figure 1-3 The present application is described in detail with reference to embodiments.

[0035] According to the shock absorber assembly 100 of the embodiment of the present application, the shock absorber assembly 100 can be applied to the hydraulic lifting suspension system of the vehicle. The height of the vehicle body can be adjusted through the shock absorber assembly 100, and it can have a good buffering effect on road excitation.

[0036] Among them, the hydraulic lifting suspension system changes the height by changing the internal oil pressure of the hydraulic cylinder 1, thereby improving the vehicle's passability. At the same time, the hydraulic lifting suspension system can be designed for different lifting scenarios, and has the characteristic that the bias frequency remains basically constant as the load increases, which to a certain extent takes into account the vehicle's passability and handling stability.

[0037] The shock absorber assembly 100 according to the present application includes a hydraulic cylinder 1 , a shock absorbing block 2 , a support assembly 3 and a shock absorbing spring 4 .

[0038] The base 12 of the hydraulic cylinder 1 is provided with a liquid injection port 121. The hydraulic cylinder 1 has a hydraulic chamber. The driving medium (such as hydraulic oil, etc.) can flow into the hydraulic chamber through the liquid injection port 121 to realize the lifting action of the hydraulic cylinder 1; the driving medium in the hydraulic chamber can also be discharged from the liquid injection port 121 to realize the falling action of the hydraulic cylinder 1. In this way, the height adjustment of the vehicle body can be realized.

[0039] Reference Figure 2 The vibration damping block 2 is sleeved on the base 12, the support assembly 3 is embedded and connected to the vibration damping block 2, and part of the base 12 passes through the vibration damping block 2 and extends out of the support assembly 3, so that the injection port 121 is arranged at a position suitable for avoiding the vibration damping block 2.

[0040] Furthermore, the support assembly 3 is used to be connected to the shock tower of the vehicle, and the force at the hydraulic cylinder 1 is transmitted to the support assembly 3 after being buffered by the shock block 2, and is further transmitted to the shock tower by the support assembly 3. During the transmission process of the force at the hydraulic cylinder 1, the shock block 2 can buffer the force transmitted from the hydraulic cylinder 1 to the support assembly 3, so as to reduce the impact of the force generated at the hydraulic cylinder 1 on the shock tower.

[0041] Reference Figure 1 The damping spring 4 is sleeved on the hydraulic cylinder 1, and the two ends of the damping spring 4 are respectively connected to the damping member 33 of the support assembly 3 and the hydraulic cylinder 1. The force of the damping spring 4 is transmitted to the support assembly 3 after being buffered by the damping member 33, and further transmitted to the damping tower (i.e., the side of the vehicle body) through the support assembly 3. During the transmission process of the force at the damping spring 4, the force transmitted from the damping spring 4 to the support assembly 3 can be buffered by the damping member 33, so as to reduce the impact of the force at the damping spring 4 on the damping tower.

[0042] It should be noted that, at present, the shock absorber and spring structure of the hydraulic lifting suspension system are integrated, and the shock absorber is installed on the vehicle body through the support structure. In the related technology, the internal oil pressure of the shock absorber can reach more than 20Mpa. When the load of the spring and the internal oil pressure of the shock absorber are transferred to the support structure, the impact force on the support structure is relatively large, and the support structure cannot effectively buffer the impact force, affecting the NVH (Noise, Vibration, Harshness: noise, vibration and sound roughness) performance of the whole vehicle.

[0043] In the present application, the damping spring 4 is connected to the support assembly 3 through the damping member 33, and the load of the damping spring 4 is transmitted to the support assembly 3 after being buffered by the damping member 33; the hydraulic cylinder 1 is connected to the support assembly 3 through the damping block 2, and the force at the hydraulic cylinder 1 is transmitted to the support assembly 3 after being buffered by the damping block 2. As a result, the forces of the damping spring 4 and the hydraulic cylinder 1 can be transmitted to the support assembly 3 respectively, so that the load of the damping spring 4 and the internal oil pressure of the hydraulic cylinder 1 are fed back to the support assembly 3 in a dual-channel manner, thereby avoiding excessive local force on the support assembly 3, reducing the impact on the vehicle body, and extending the service life and working stability of the shock absorber assembly 100, and reducing the abnormal working noise of the shock absorber assembly 100, so as to improve the driving experience of the vehicle.

[0044] It is understandable that, in the present application, the base 12 of the hydraulic cylinder 1 is connected to the support assembly 3 through the shock absorber block 2, and the support assembly 3 is used to connect to the shock absorber tower on the vehicle body. When the shock absorber assembly 100 is assembled to the vehicle, the support assembly 3 is arranged at the upper end of the shock absorber assembly 100 and is used to connect to the shock absorber tower, that is, the injection port 121 for the driving medium to enter the hydraulic cylinder 1 is formed in the upper area of ​​the shock absorber assembly 100, and the hydraulic cylinder 1 can supply the driving medium to flow in or out through the top, realizing the upper end inlet and outlet of the liquid, and the oil circuit is arranged in the upper area of ​​the shock absorber assembly 100.

[0045] like Figure 3 As shown, in some embodiments of the present application, the vibration damping block 2 is provided with a slot 201, which is recessed from the outer peripheral wall of the vibration damping block 2 toward the center side, and the support assembly 3 includes a first support 31, and the first support 31 is formed with a snap-fitting flange 311, which is snap-fitted with the slot 201.

[0046] Reference Figure 2 and Figure 3 The vibration-damping block 2 is formed with a through hole for the base 12 to pass through and is arranged through along a first direction, and the vibration-damping block 2 is sleeved on the base 12 along the first direction, and the first direction is also the extension and contraction direction of the hydraulic cylinder 1.

[0047] In a specific embodiment of the present application, the cross-sectional projection of the vibration damping block 2 in the first direction is annular, the slot 201 extends radially toward one side of the central axis, and the slot 201 is arranged around the through hole in the circumferential direction to construct the slot 201 as an annular groove.

[0048] Correspondingly, the clamping flange 311 is arranged in an annular shape, and the clamping flange 311 can be clamped and embedded in the clamping slot 201. Among them, the two wall surfaces of the clamping flange 311 in the first direction can be arranged in abutment with the two groove walls of the clamping slot 201 arranged oppositely in the first direction, so that the clamping flange 311 is limited with the vibration damping block 2 in the first direction, and the clamping flange 311 is clamped into the clamping slot 201 in the circumferential direction, which can prevent the first support 31 from moving relative to the vibration damping block 2 in a direction perpendicular to the first direction (which is also the radial direction of the vibration damping block 2), thereby improving the connection reliability between the clamping slot 201 and the clamping flange 311.

[0049] In some embodiments of the present application, the vibration damping block 2 includes: a first vibration damping portion 21 and a second vibration damping portion 22, the first vibration damping portion 21 is sleeved on the base 12, and the first vibration damping portion 21 is clamped between the base 12 and the first support 31, the second vibration damping portion 22 is connected to the first vibration damping portion 21, and a slot 201 is formed between the first vibration damping portion 21 and the second vibration damping portion 22.

[0050] like Figure 2 As shown, after the vibration damping block 2 is snap-fitted with the first support 31, the first vibration damping portion 21 and the second vibration damping portion 22 are respectively arranged on both sides of the first support 31, and the first vibration damping portion 21 and the second vibration damping portion 22 can clamp and limit the snap-fit ​​flange 311 in the first direction to buffer the load on the snap-fit ​​flange 311 in the first direction and reduce the force transmitted to the first support 31 through the vibration damping block 2.

[0051] like Figure 1 As shown, in a further embodiment of the present application, the shock absorber assembly 100 further includes a liquid injection seat 5 , which is formed with a liquid injection cavity 51 . The liquid injection seat 5 is sleeved on the base 12 , and the liquid injection cavity 51 is connected to the liquid injection port 121 .

[0052] The filling seat 5 is used to communicate with the oil supply device of the hydraulic cylinder 1 , and the oil supply device can inject driving medium into the filling seat 5 . The driving medium can fill the filling cavity 51 and further transport it to the hydraulic cavity of the hydraulic cylinder 1 through the filling port 121 .

[0053] It is understandable that the injection port 121 formed on the base 12 is small in size, and it is not convenient to directly connect the injection port 121 to the oil circuit through the pipeline structure. In the present application, by connecting the injection seat 5 to the base 12, and connecting the injection cavity 51 to the injection port 121, so as to inject the driving medium into the injection port 121 through the injection cavity 51, the pipeline structure can be connected to the interface of the injection seat 5, so as to connect the injection port 121 to the oil circuit.

[0054] In some embodiments of the present application, a seal is provided in the filling seat 5, and the seal is provided between the base 12 and the filling seat 5 to improve the sealing effect between the base 12 and the filling seat 5, prevent leakage of the driving medium, and improve the reliability of the oil filling process of the shock absorber assembly 100.

[0055] The sealing member may be configured as a sealing ring, which is embedded in the inner wall of the liquid injection seat 5 and arranged around the circumferential direction of the base 12 to form a seal between the base 12 and the liquid injection seat 5 .

[0056] like Figure 2 As shown, in some embodiments of the present application, the shock absorber assembly 100 further includes a gasket 6, which is sleeved on the base 12, and the gasket 6 is sandwiched between the liquid injection seat 5 and the second shock absorbing part 22 to improve the tightness of the fit between the liquid injection seat 5 and the first shock absorbing part 21. Among them, since the gasket 6 can play a role in transmitting pressure or tension, the force state of the fitting point between the liquid injection seat 5 and the first shock absorbing part 21 can be controlled by adjusting the gasket 6, thereby improving the assembly reliability, further buffering the impact between components (such as: between the liquid injection seat 5 and the shock absorbing block 2), and improving the impact resistance of the hydraulic cylinder 1 on the liquid injection side.

[0057] In some embodiments of the present application, a threaded section 122 is provided at the end of the base 12, at least part of the threaded section 122 passes through the liquid injection seat 5, and the threaded section 122 is threadedly matched with the threaded connector 7 to fix the liquid injection seat 5 to the base 12.

[0058] Furthermore, the threaded segment 122 is arranged at the upper end of the base 12 in the first direction, and at least part of the threaded segment 122 extends out when the filling seat 5 is sleeved on the base 12. The part of the threaded segment 122 extending out of the filling seat 5 can be threadedly matched with the threaded connecting part 7 (such as a nut, etc.) to press the filling seat 5 to be fixed on the base 12. The connection method is simple and has high reliability.

[0059] like Figure 2 As shown, in some embodiments of the present application, the support assembly 3 further includes a second support 32, the second support 32 is connected to the first support 31, and the vibration reduction member 33 is disposed on the second support 32. The second support 32 can be fixedly connected to the first support 31 by welding or the like.

[0060] In some embodiments of the present application, the first support 31 is provided with a mounting hole 313, and the mounting hole 313 is used for the connection member 9 to pass through, so as to connect the first support 31 with the vibration reduction tower through the connection member 9. The connection member 9 can be constructed as a bolt, which is passed through the mounting hole 313 from bottom to top, and is threadedly connected with the threaded structure (such as threaded hole, nut, etc.) at the vibration reduction tower to fix the first support 31 with the vibration reduction tower.

[0061] Reference Figure 1 In a further embodiment of the present application, the first support 31 is provided with a mounting boss 312, the mounting boss 312 bulges toward a side away from the second support 32, and an installation space is reserved between the mounting boss 312 and the second support 32, and the connecting piece can be avoided at the installation space.

[0062] Among them, when the connecting member is constructed as a bolt 8, the threaded rod of the bolt 8 can be passed through the first support 31 from bottom to top and used to connect with the vibration damping tower. The bolt head of the bolt 8 is arranged between the first support 31 and the vibration damping member 33, that is, the bolt head is arranged in the installation space formed by the installation boss 312.

[0063] In some embodiments of the present application, the shock absorber 33 is arranged on the side of the second support 32 away from the first support 31, that is, the shock absorber 33 is arranged on the lower side of the second support 32, and the shock absorber 33 is connected to the shock absorber spring 4. The force of the shock absorber spring 4 can act on the shock absorber 33 and be further transmitted to the second support 32 and the first support 31 after being buffered by the shock absorber 33.

[0064] In a specific embodiment of the present application, the vibration damping member 33 is constructed as a rubber bearing, which includes a bearing and a vibration damping pad, the bearing is connected to the vibration damping spring 4, the vibration damping pad is press-fitted and fixed on the bearing, and the rubber bearing is mounted on the second support 32 by a clamping method. The force of the vibration damping spring 4 first acts on the rubber bearing, and is further transmitted to the second support 32 and the first support 31 after being buffered by the rubber bearing, and finally fed back to the vehicle body side (such as: the vibration damping tower) through the first support 31.

[0065] like Figure 2 As shown, in some embodiments of the present application, the hydraulic cylinder 1 includes a cylinder barrel 11 and a base 12, the base 12 is arranged at the end of the cylinder barrel 11, and the shock absorber assembly 100 also includes a piston 13, one end of the piston 13 extends into the cylinder barrel 11, the piston 13 is slidably arranged in the cylinder barrel 11 along a first direction, and a hydraulic chamber for accommodating a driving medium is jointly defined by the piston 13, the cylinder barrel 11 and the base 12.

[0066] In a further embodiment of the present application, the base 12 can be fixed to the cylinder barrel 11 by welding. The welding fixing method is simple and easy to operate and has high connection reliability, which can improve the strength of the end of the hydraulic cylinder 1.

[0067] Reference Figure 2 The base 12 includes a connecting portion and a liquid injection section. The connecting portion is used to be fixedly connected to the end of the cylinder 11, and the liquid injection section is formed with a liquid injection port 121 and a liquid injection channel.

[0068] Reference Figure 2 The injection ports 121 are multiple and are arranged at intervals in the first direction. Each injection port 121 is arranged to penetrate the injection section in the radial direction to increase the communication area between the base 12 and the injection cavity 51 and improve the injection efficiency.

[0069] The above “liquid injection efficiency” includes not only the efficiency of conveying the driving medium into the base 12 through the liquid injection cavity 51 , but also the efficiency of discharging the driving medium into the liquid injection cavity 51 by the base 12 .

[0070] like Figure 1 As shown, in some embodiments of the present application, the hydraulic cylinder 1 is further provided with a bracket 14, the bracket 14 is connected to the outer wall of the cylinder barrel 11, the bracket 14 and the shock-absorbing member 33 are arranged opposite to each other in the first direction, and the shock-absorbing spring 4 is elastically connected between the shock-absorbing member 33 and the bracket 14, that is, one end of the shock-absorbing spring 4 is connected to the shock-absorbing member 33, and the other end of the shock-absorbing spring 4 is connected to the bracket 14.

[0071] In some embodiments of the present application, one end of the hydraulic cylinder 1 is connected to the shock absorber block 2 through the base 12, and is connected to the first support 31 and the vehicle body through the shock absorber block 2. The other end of the hydraulic cylinder 1 is provided with a connecting structure (such as a connecting bushing) and is connected to the suspension assembly through the connecting structure.

[0072] Among them, when the connection structure is constructed as a connection bushing, the connection bushing has a good buffering effect on vibration, thereby improving the impact resistance of the connection between the hydraulic cylinder 1 and the suspension assembly.

[0073] Therefore, the shock absorber assembly 100 in the present application has at least the following advantages:

[0074] (1) The hydraulic cylinder 1 is connected to the support assembly 3 through the vibration-damping block 2 so as to buffer the force transmitted from the hydraulic cylinder 1 to one side of the support assembly 3 through the vibration-damping block 2; the vibration-damping spring 4 is connected to the support assembly 3 through the vibration-damping member 33 so as to buffer the force transmitted from the vibration-damping spring 4 to one side of the support assembly 3 through the vibration-damping member 33.

[0075] As a result, two force transmission paths are formed between the shock absorbing spring 4, the hydraulic cylinder 1 and the support assembly 3, that is, the shock absorbing spring 4 is transmitted to the support assembly 3 via the shock absorbing member 33, and the hydraulic cylinder 1 is transmitted to the support assembly 3 via the shock absorbing block 2. This can avoid the forces of the shock absorbing spring 4 and the hydraulic cylinder 1 being concentrated in one place, prevent the support assembly 3 from being subjected to excessive local force, and mitigate the force transmitted from the suspension assembly side of the vehicle body to reduce the impact on the vehicle body. It can also extend the service life and working stability of the shock absorber assembly 100, and can also reduce the abnormal working noise of the shock absorber assembly 100 to improve the driving experience of the vehicle.

[0076] (2) The filling port 121 of the hydraulic cylinder 1 in the present application (i.e., the connection position with the oil circuit) is arranged at the upper part of the shock absorber assembly 100, so that the oil circuit can be arranged on the side close to the vehicle body, thereby avoiding the oil circuit being affected by the suspension assembly and causing greater difficulty in arrangement.

[0077] According to the vehicle of the embodiment of the present application, the vehicle includes the above-mentioned shock absorber assembly 100. By setting the above-mentioned shock absorber assembly 100, the impact on the vehicle body can be weakened, and the service life and working stability of the shock absorber assembly 100 can be extended, and the abnormal working noise of the shock absorber assembly 100 can be reduced, so as to improve the driving experience of the vehicle.

[0078] The advantages of the vehicle and the shock absorber assembly 100 described above over the prior art are the same and will not be described in detail herein.
