[0030] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0031] Reference below Figure 1-Figure 4A shock absorber assembly 10 for a vehicle according to an embodiment of the present application is described. The shock absorber assembly 10 includes a shell 11, a support frame 12 and a piston rod 13. A accommodating cavity 111 is formed in the shell 11. The support frame 12 is arranged at one end of the shell 11 in the axial direction and is suitable for connecting with the vehicle body. At least a portion of the piston rod 13 is accommodated in the accommodating cavity 111. An adjusting portion 131 is formed at one end of the piston rod 13 in the axial direction toward the support frame 12. The adjusting portion 131 cooperates with the support frame 12 and can selectively rotate relative to the support frame 12 to drive the piston rod 13 to move in the axial direction.

[0032] At present, all parameters of the finished parts inside the vehicle's shock absorber assembly have been solidified, so that the shock absorber assembly can only provide the damping coefficient in a single way. During the actual vehicle verification process, in order to improve the performance of the whole vehicle and optimize the stretching stroke of the existing shock absorber solution, it is necessary to re-commission the supplier to produce parts. For example, the piston rod needs to be reprocessed to increase the shock absorber stretching contact gap to adjust the contact and stretching stroke. The assembly manufacturing cycle and replacement time are long and the cost investment is high.

[0033] like Figure 1 As shown, specifically, the shock absorber assembly 10 includes a shell 11, a support frame 12 and a piston rod 13. A accommodating cavity 111 may be formed in the shell 11. The support frame 12 may be arranged on one side of the shell 11 in the axial direction, and the support frame 12 may be connected to the vehicle body to fix the shock absorber assembly 10 to the vehicle body. At least a portion of the piston rod 13 may be accommodated in the accommodating cavity 111, and an adjusting portion 131 is formed at one end of the piston rod 13 facing the support frame 12 in the axial direction. The adjusting portion 131 can extend to the outside of the accommodating cavity 111 and cooperate with the support frame 12, wherein the adjusting portion 131 can rotate relative to the support frame 12, thereby driving the piston rod 13 to move in the axial direction and changing the stretching stroke.

[0034] It should be noted that if Figure 2As shown, a cylinder body 15 is also provided in the accommodating chamber 111, and a vibration reduction chamber 151 can be formed in the cylinder body 15. A part of the piston rod 13 can be accommodated in the vibration reduction chamber 151, and a piston valve 133 is also formed at one end of the piston rod 13 facing the cylinder body 15. A limit support 134 is also provided on the piston rod 13. The limit support 134 can be located between the inner wall of the cylinder body 15 on the side facing the support frame 12 and the piston valve 133, and the distance between the limit support 134 and the inner wall of the shell 11 on the side facing the support frame 12 is the stretching stroke. When the piston rod When 13 rotates relative to the supporting frame 12, the piston rod 13 can move axially toward or away from the side of the cylinder body 15, thereby increasing or decreasing the stretching stroke. During the actual vehicle verification process, the stretching stroke can be changed by only rotating the piston rod 13, which effectively saves the solution verification time, reduces the verification cost investment and the labor time of manual part replacement. During actual driving, the stretching stroke can be adjusted according to different molding and chassis heights to make the vehicle run stably and meet user needs. It should be noted that the axial direction referred to in this application is the axial direction of the piston rod 13.

[0035] In short, the shock absorber assembly 10 of the embodiment of the present application has a shell 11, a support frame 12 and a piston rod 13. The support frame 12 is connected to the shell 11 and the vehicle body respectively. The piston rod 13 is arranged in the shell 11, and the piston rod 13 can rotate relative to the support frame 12 to drive the piston rod 13 to move axially, thereby changing the stretching stroke of the piston rod 13. During the actual vehicle verification process, the solution verification time can be saved and the cost can be saved. The shock absorber assembly 10 can also adjust the stretching stroke according to different moldings and chassis heights to make the vehicle run stably and improve the user's driving experience.

[0036] like Figure 3 As shown, in some embodiments of the present application, the piston rod 13 can be axially penetrated through the support skeleton 12, and the inner circumferential wall of the support skeleton 12 can be formed with a first threaded portion 121, and the outer circumferential wall of the adjustment portion 131 can be formed with a second threaded portion 1311, and the first threaded portion 121 and the second threaded portion 1311 can be threadedly matched. The threaded connection can be used to facilitate the rotation of the piston rod 13 to adjust the stretching stroke, and the piston rod 13 can also achieve axial displacement during the rotation process, converting the circumferential rotation into axial movement, thereby changing the stretching stroke and improving the reliability of the piston rod 13.

[0037] like Figure 3 and Figure 4As shown, in some embodiments of the present application, the support skeleton 12 may include a skeleton body 122 and a support plate 123, the end of the skeleton body 122 can be connected to the shell 11, and the skeleton body 122 can be sleeved on the outer periphery of the shell 11, and a first threaded portion 121 can be formed inside the skeleton body 122, and the first threaded portion 121 can be threadedly matched with the second threaded portion 1311, and a through hole 1221 is also formed on the skeleton body 122, and the through hole 1221 can be used to install the piston rod 13, and a portion of the piston rod 13 can be passed through the through hole 1221. The support plate 123 can be arranged at one end of the skeleton body 122 away from the shell 11, and the support plate 123 can extend in the radial direction, and the support plate 123 can be connected to the vehicle body. Furthermore, a mounting hole 1231 that is axially through-set can be formed on the support plate 123, and the mounting hole 1231 can be arranged corresponding to the vehicle body. The shock absorber assembly 10 can also include a fastener, which can be passed through the mounting hole 1231 and cooperate with the vehicle body to fix the support plate 123 to the vehicle body, thereby installing the shock absorber assembly 10 on the vehicle body.

[0038] like Figure 3 and Figure 4 As shown, in some embodiments of the present application, a first extension portion 124 is formed in the skeleton body 122, and the first extension portion 124 can extend toward the piston rod 13, wherein the first extension portion 124 can be constructed in a ring shape, and the inner circumferential wall of the first extension portion 124 can be formed with a first threaded portion 121, and the inner circumferential wall of the first extension portion 124 can be the wall surface of the first extension portion 124 facing the piston rod 13. By providing the first extension portion 124, the piston rod 13 can maintain a certain distance from the skeleton body 122 during the movement, thereby preventing the piston rod 13 from contacting the skeleton body 122 and affecting the vibration reduction performance.

[0039] Furthermore, a second extension portion 125 extending axially is formed at one end of the first extension portion 124 toward the piston rod 13, and a third threaded portion can be formed on the inner wall of the second extension portion 125, which can be threadedly matched with the second threaded portion 1311. The use of the second extension portion 125 can increase the contact area with the piston rod 13, thereby increasing the structural strength.

[0040] like Figure 3As shown, in some embodiments of the present application, the shock absorber assembly 10 further includes a stopper 14, which can be arranged on the side of the first extension 124 away from the housing 11, and the stopper 14 can be sleeved on the outer periphery of the adjustment portion 131, and the stopper 14 can cooperate with the second threaded portion 1311 to achieve secondary fixation of the piston rod 13. It should be noted that the piston rod 13 is first fixed with the first extension 124 and the second extension 125 through threaded connection. Since the piston rod 13 does not rotate during actual movement, the piston rod 13 can be fixed with the first extension 124 and the second extension 125, and the stopper 14 is sleeved on the outer periphery of the adjustment portion 131 and cooperates with the second threaded portion 1311. The stopper 14 can also abut against the first extension 124, thereby achieving the second fixation of the piston rod 13. The two-time fixation method can improve the stability of the cooperation between the piston rod 13 and the support frame 12.

[0041] like Figure 4 As shown, in some embodiments of the present application, an adjustment end 132 is also formed at the end of the piston rod 13 away from the housing 11. The user or staff can adjust the adjustment end 132 through a tool to achieve rotation of the piston rod 13. The cross-section of the adjustment end 132 along the radial direction of the piston rod 13 is a polygon. The above structure can facilitate adjustment by the user or staff.

In actual use, the shock absorber assembly 10 can also adjust the stretching stroke according to different moldings and chassis heights to make the vehicle run stably and improve the user's driving experience.
