[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-Figure 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 embodiment of the present application includes: a hydraulic cylinder 1 , a shock absorbing bushing 2 , a shock absorbing spring 4 and a support assembly 3 .

[0038] The base 11 of the hydraulic cylinder 1 is provided with a liquid injection hole 101, and the hydraulic cylinder 1 has a hydraulic cavity, and the liquid injection hole 101 is used to connect the hydraulic cavity with the oil circuit structure, so as to adjust the amount of the driving medium in the hydraulic cylinder 1. For example, the driving medium (such as hydraulic oil, etc.) can flow into the hydraulic cavity through the liquid injection hole 101 to realize the lifting action of the hydraulic cylinder 1; the driving medium in the hydraulic cavity can also be discharged from the liquid injection hole 101 to realize the falling action of the hydraulic cylinder 1.

[0039] like Figure 3 As shown, the vibration-damping bushing 2 is sleeved and connected to the base 11 of the hydraulic cylinder 1 . The force generated at the hydraulic cylinder 1 can be transmitted to the vibration-damping bushing 2 through the base 11 , and the force is buffered by the vibration-damping bushing 2 .

[0040] Reference Figure 3 The support assembly 3 is fixedly connected to the vibration damping bushing 2, and part of the base 11 extends out of the support assembly 3, exposing the injection hole 101 from one side of the support assembly 3, so as to realize the liquid inlet and outlet from the upper end of the shock absorber assembly 100, and facilitate the connection between the base 11 and the oil circuit structure, such as: installing and matching the injection seat with the base 11.

[0041] Among them, the support assembly 3 is used to be connected to the shock-absorbing tower, that is, in the process of the hydraulic cylinder 1 feeding back the force to the shock-absorbing tower, the shock-absorbing bushing 2 can buffer the force to alleviate the force generated by the change in oil pressure inside the hydraulic cylinder 1, and reduce the force transmitted from the hydraulic cylinder 1 to the bracket 14 assembly, thereby weakening the impact transmitted from the support assembly 3 to the vehicle body (i.e., the shock-absorbing tower).

[0042] Furthermore, 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 support assembly 3 and the hydraulic cylinder 1, that is, the force of the damping spring 4 can be directly fed back to the support assembly 3. In other words, the position where the force of the damping spring 4 acts on the support assembly 3 is different from the position where the force of the hydraulic cylinder 1 acts on the support assembly 3, which can avoid excessive force on the support assembly 3, increase the service life of the support assembly 3, and enhance the buffering effect of the shock absorber assembly 100 on the force acting on the suspension to the vehicle body side.

[0043] 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 force generated by the internal oil pressure of the shock absorber are transmitted 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.

[0044] In the present application, the force fed back by the damping spring 4 can act directly on the support assembly 3, and the hydraulic cylinder 1 is connected to the support assembly 3 through the damping bushing 2. The force of the hydraulic cylinder 1 is transmitted to the support assembly 3 after being buffered by the damping bushing 2 to reduce the impact force on the support assembly 3. Therefore, the forces of the damping spring 4 and the hydraulic cylinder 1 can be transmitted to the support assembly 3 respectively, so that the force generated by the damping spring 4 and the internal oil pressure of the hydraulic cylinder 1 can be fed back to the support assembly 3 through dual channels, 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. It can also reduce the abnormal working noise of the shock absorber assembly 100 to improve the driving experience of the vehicle.

[0045] like Figure 3 As shown, in some embodiments of the present application, the support assembly 3 includes: a support body 31 and a cover body 32, the support body 31 has a mounting groove open on one side, the vibration-damping bushing 2 is arranged in the mounting groove, the cover body 32 is arranged at the open end of the mounting groove, and the cover body 32 is connected to the support body 31 to fix the vibration-damping bushing 2 in the mounting groove through the cover body 32.

[0046] The cover 32 is arranged at the open end of the mounting groove to prevent the vibration-damping bushing 2 from coming out of the open end of the mounting groove, and the cover 32 can limit the vibration-damping bushing 2, thereby pressing the vibration-damping bushing 2 against the inner flange 311 of the mounting groove, thereby improving the connection reliability between the vibration-damping bushing 2 and the support assembly 3, and ensuring the buffering effect of the vibration-damping bushing 2 on the force transmitted from the base 11 to the support assembly 3. The inner flange 311 is equivalent to the bottom wall structure of the mounting groove, and can be used to support the vibration-damping bushing 2, so as to fix the vibration-damping bushing 2 through the cooperation of the cover 32 and the inner flange 311.

[0047] It is understandable that if the vibration-damping bushing 2 can move or shake relative to the support assembly 3, the reliability of the connection between the base 11 and the support assembly 3 through the vibration-damping bushing 2 cannot be guaranteed, so the vibration-damping bushing 2 and the support assembly 3 are fixedly connected.

[0048] Reference Figure 2In some embodiments of the present application, a avoidance hole 321 is formed at the cover body 32, and the avoidance hole 321 can allow the base 11 to extend out, and can allow the injection seat (not shown in the figure) to extend into the mounting groove and be sleeved on the base 11, the injection seat has an injection cavity, the injection cavity is connected to the injection hole 101, and the injection seat has an injection interface connected to the oil supply device, the oil supply device can inject a driving medium into the injection seat, the driving medium can fill the injection cavity, and further transport it to the hydraulic cavity of the hydraulic cylinder 1 through the injection hole 101.

[0049] It is understandable that the injection hole 101 formed on the base 11 is small in size, and it is not convenient to directly connect the injection hole 101 to the oil circuit structure through the pipeline structure. In the present application, the injection seat is connected to the base 11, and the injection cavity is connected to the injection hole 101, so as to inject the driving medium into the injection hole 101 through the injection cavity.

[0050] Furthermore, a sealing member is provided in the injection seat, and the sealing member is provided between the base 11 and the injection seat to improve the sealing effect between the base 11 and the injection seat, prevent leakage of the driving medium, and improve the reliability of the oil injection process of the shock absorber assembly 100. The sealing member can be configured as a sealing ring, which is embedded on the inner wall of the injection seat and arranged in the circumferential direction of the base 11 to form a seal between the base 11 and the injection seat.

[0051] like Figure 3 As shown, in some embodiments of the present application, the support body 31 is provided with an inner flange 311, the inner flange 311 is arranged opposite to the cover body 32, and the vibration-damping bushing 2 is arranged between the inner flange 311 and the cover body 32, and the inner flange 311 is formed with an avoidance hole 3111 for the base 11 to pass through, so as to prevent interference between the base 11 and the inner flange 311. Among them, the base 11 can be sequentially penetrated with the inner flange 311, the vibration-damping bushing 2 and the cover body 32 from bottom to top.

[0052] Reference Figure 3 The inner flange 311 can support the vibration-damping bushing 2, and the inner flange 311 cooperates with the cover 32 to clamp and limit the vibration-damping bushing 2 in the first direction, thereby fixing the vibration-damping bushing 2 in the installation groove. The "first direction" is the direction in which the vibration-damping bushing 2 is passed through the base 11.

[0053] like Figure 3 As shown, in some embodiments of the present application, the vibration-damping bushing 2 includes: a core 21 and a vibration-damping rubber 22 .

[0054] The core 21 is sleeved on the base 11, the vibration-damping rubber 22 is integrally arranged with the core 21, and the vibration-damping rubber 22 is arranged in the mounting groove, and the axial ends of the vibration-damping rubber 22 are respectively abutted against the inner wall of the cover 32 and the inner wall of the inner flange 311. Thus, the vibration-damping rubber 22 can be limited and fixed by the cover 32 and the inner flange 311 to improve the matching reliability of the vibration-damping bushing 2 and the support assembly 3. It can be understood that the axial direction of the vibration-damping rubber 22 is the same as the first direction mentioned above.

[0055] In a further embodiment of the present application, the vibration-damping rubber 22 may be interference-fitted with the inner circumferential wall of the mounting groove to further enhance the tightness of the fit between the vibration-damping bushing 2 and the support body 31 , thereby ensuring the buffering effect of the vibration-damping bushing 2 on impact force.

[0056] like Figure 3 As shown, in some embodiments of the present application, the base 11 includes a positioning section 111, which is arranged on the side of the core 21 away from the cover 32 and is used to support and position the core 21 to prevent the core 21 mounted on the base 11 from moving.

[0057] The base 11 is fixedly connected to the core 21, for example, a fixing groove is formed on the outer peripheral wall of the base 11, and the core 21 can be embedded and fixed in the fixing groove to fix the base 11 to the core 21, and the positioning section 111 is arranged on one side of the core 21 to prevent the core 21 from moving downward in the first direction relative to the base 11, thereby improving the connection reliability between the base 11 and the core 21. It should be noted that the matching method between the base 11 and the core 21 is not limited to this, and the base 11 and the core 21 can also be connected by interference fit.

[0058] Furthermore, the base 11 also includes an injection section 112 connected to the positioning section 111. The injection section 112 penetrates the core body 21, and the injection hole 101 is formed on the injection section 112, so that the injection hole 101 is set at a position suitable for avoiding the vibration damping bushing 2 and facilitating communication and cooperation with the injection cavity.

[0059] Reference Figure 3 It can be seen that the radial dimension of the positioning section 111 is greater than the radial dimension of the injection section 112 , so that the portion of the positioning section 111 protruding radially from the injection section 112 can be abutted against the core body 21 to position the core body 21 .

[0060] like Figure 3 As shown, in some embodiments of the present application, the injection section 112 is provided with a plurality of injection holes 101, each injection hole 101 is arranged through the injection section in a radial direction, and the plurality of injection holes 101 are arranged at intervals in the axial direction of the injection section 112, so as to increase the connection area between the base 11 and the injection cavity by increasing the number of injection holes 101, thereby improving the injection efficiency.

[0061] like Figure 1 As shown, in some embodiments of the present application, the support body 31 is provided with a positioning protrusion 312, which is arranged on the side surface of the support body 31 opposite to the vibration damping tower and protrudes toward the side of the vibration damping tower. The positioning protrusion 312 is used to position and cooperate with the vibration damping tower to assist in assembling the support body 31 and the vibration damping tower.

[0062] like Figure 1 As shown, in some embodiments of the present application, the support body 31 is also provided with a plurality of mounting holes, which are arranged throughout the support body 31 and are used for connecting members to pass through so as to fix the support body 31 to the vibration damping tower through the connecting members.

[0063] Among them, the connecting part can be specifically constructed as a bolt, and the screw section of the bolt can pass through the support theme from bottom to top from the mounting hole, and threadedly cooperate with the threaded hole or threaded structure (such as: a mounting seat with a threaded hole) formed on the side of the shock absorber tower to connect the support assembly 3 to the vehicle body.

[0064] In some embodiments of the present application, the support assembly 3 also includes a vibration damper 33, which is arranged at the lower part of the support assembly 3, and the vibration damper spring 4 is connected to the vibration damper 33 at one end adjacent to the support assembly 3 so as to be connected to the support assembly 3 through the vibration damper assembly.

[0065] The vibration damping member 33 can be constructed as a rubber bearing, which can be mounted on the support body 31 by means of a clamping connection. The force of the vibration damping spring 4 first acts on the rubber bearing, and is further transmitted to the support body 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 support body 31, so that the vibration damping member 33 plays a buffering role on the force transmitted from the vibration damping spring 4 to the support assembly 3, weakens the impact on the support body 31, and helps to increase the service life of the support body 31.

[0066] like Figure 2 As shown, in some embodiments of the present application, the base 11 of the hydraulic cylinder 1 is provided with a liquid injection hole 101, and the hydraulic cylinder 1 includes: a cylinder barrel 12 and the above-mentioned base 11, the cylinder barrel 12 is connected to the base 11 and forms a hydraulic chamber connected to the liquid injection hole 101. The shock absorber assembly 100 also includes a piston rod 13, one end of the piston rod 13 extends from the end of the cylinder barrel 12 away from the base 11, and the piston rod 13 can move closer to or farther away from the side of the base 11 relative to the cylinder barrel 12.

[0067] It can be understood that when the driving medium is injected into the hydraulic chamber through the injection hole 101, the piston rod 13 moves to the side away from the base 11 under the action of the driving medium; when the driving medium in the hydraulic chamber needs to be discharged, the driving medium in the hydraulic chamber can be pressed out under the action of the gravity of the vehicle body itself and recovered through the oil circuit structure.

[0068] In some optional embodiments, the base 11 can be connected to the cylinder barrel 12 by welding. The welding fixing method is simple and easy to operate and has high connection reliability, and can improve the strength of the end of the hydraulic cylinder 1.

[0069] like Figure 1 As shown, in some embodiments of the present application, the shock absorber assembly 100 includes a dust cover 5, which is sleeved on the hydraulic cylinder 1 and connected to the support assembly 3, and a portion of the dust cover 5 is provided between the support assembly 3 (such as: the shock absorbing member 33 of the support assembly 3) and the shock absorbing spring 4, so that the dust cover 5 is fixed to the support assembly 3 through the shock absorbing spring 4. Therefore, the dust cover 5 has a dustproof protection effect on the hydraulic cylinder 1.

[0070] like Figure 1 As shown, in some embodiments of the present application, the hydraulic cylinder 1 is further provided with a bracket 14, which is connected to the outer wall of the cylinder barrel 12, the bracket 14 and a part of the support assembly 3 are arranged relative to each other in the first direction, and the shock-absorbing spring 4 is elastically connected between the manufacturing assembly and the bracket 14, that is, one end of the shock-absorbing spring 4 is connected to the support assembly 3, 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-absorbing bushing 2 through the base 11, and is connected to the support assembly 3 and the vehicle body through the shock-absorbing bushing 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 bushing 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 bushing 2; the vibration-damping spring 4 is connected to the support assembly 3.

[0075] As a result, two force transmission paths are formed between the hydraulic cylinder 1, the shock absorbing spring 4 and the support assembly 3, namely, the shock absorbing spring 4 transmits the force to the support assembly 3, and the hydraulic cylinder 1 transmits the force to the support assembly 3 via the shock absorbing bushing 2, thereby avoiding the forces of the shock absorbing spring 4 and the hydraulic cylinder 1 from being concentrated in one place, preventing the support assembly 3 from being subjected to excessive local force, and mitigating the force transmitted from the suspension assembly side of the vehicle body to reduce the impact on the vehicle body, and can 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 injection hole 101 of the hydraulic cylinder 1 in the present application (i.e., the connection position with the oil circuit structure) is arranged at the upper part of the shock absorber assembly 100, so that the oil circuit structure can be arranged on the side close to the vehicle body, thereby avoiding interference between the oil circuit structure and the suspension assembly.

[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.

[0079] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
