[0032] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model will be described in detail below.

[0033] Reference will be made below to Figures 1 - 3 describe a shock absorber assembly 100 according to an embodiment of the present utility model. The shock absorber assembly 100 can be applied to a vehicle.

[0034] In combination with Figures 1 - 3 As shown, the shock absorber assembly 100 according to the present utility model may mainly include: a shock absorber 10. Among them, the shock absorber 10 may mainly include: a cylinder barrel 11, a piston rod assembly 12, and a guide seat 13. The piston rod assembly 12 is movably disposed in the cylinder barrel 11. The piston rod assembly 12 includes a piston rod 121. The piston rod 121 passes through the guide seat 13 and is in guiding cooperation with the guide seat 13. The guide seat 13 is detachably disposed in the cylinder barrel 11.

[0035] Specifically, when the shock absorber 10 is working, the piston rod assembly 12 can move up and down within the cylinder barrel 11. In cooperation with the valve system inside the shock absorber 10, the piston rod assembly 12 can compress the shock-absorbing medium within the cylinder barrel 11 to achieve the shock-absorbing effect of the shock absorber 10. Of course, the cylinder barrel 11 is also provided with an oil seal assembly and a sealing retaining ring. The piston rod 121 passes through the oil seal assembly and the sealing retaining ring at the same time, and the oil seal assembly and the sealing retaining ring can play a sealing role.

[0036] By arranging the guide seat 13 above the inside of the cylinder barrel 11 and enabling the piston rod 121 to pass through the guide seat 13, the guide seat 13 can limit the radial direction of the piston rod 121. The guide seat 13 and the piston rod 121 are in guiding cooperation in the up and down directions, thereby playing a guiding role for the piston rod 121, preventing the piston rod 121 from shaking during movement, and improving the reliability of the shock absorber 10.

[0037] Furthermore, by detachably arranging the guide seat 13 within the cylinder barrel 11, a detachable design of the guide seat 13 can be realized, so that the shock absorber 10 has the convenience of being disassembled and replaced. When overhauling the shock absorber 10, it is convenient to replace the guide seat 13 alone, which can reduce the overhaul cost of the shock absorber assembly 100.

[0038] Therefore, by detachably arranging the guide seat 13 within the cylinder barrel 11, a detachable design of the guide seat 13 can be realized, so that the shock absorber 10 has the convenience of being disassembled and replaced. When overhauling the shock absorber 10, it is convenient to replace the guide seat 13 alone, which can reduce the overhaul cost of the shock absorber assembly 100.

[0039] Combined with Figure 3 As shown, a first thread portion 131 is provided on the outer periphery of the guide seat 13, and a second thread portion 111 is provided on the inner wall of the cylinder barrel 11. The first thread portion 131 and the second thread portion 111 are in threaded cooperation.

[0040] Specifically, by providing the first thread portion 131 on the outer periphery of the guide seat 13 and correspondingly providing the second thread portion 111 on the inner wall of the cylinder barrel 11, only by gradually screwing the guide seat 13 into the inside of the cylinder barrel 11 to make the first thread portion 131 and the second thread portion 111 in threaded cooperation with each other, the connection and fixation between the guide seat 13 and the cylinder barrel 11 can be realized. And only by gradually screwing out the guide seat 13 to release the threaded cooperation between the first thread portion 131 and the second thread portion 111, the guide seat 13 can be detached from the cylinder barrel 11. Thus, not only can the connection stability between the guide seat 13 and the cylinder barrel 11 be improved, but also the disassembly and assembly of the guide seat 13 can be made simpler and more convenient.

[0041] Combined with Figures 1 - 3As shown, the shock absorber assembly 100 may further include: a support rod 20, which is detachably connected to the end of the piston rod 121 away from the cylinder barrel 11, and the support rod 20 is adapted to be connected to the axle.

[0042] Specifically, the support rod 20 is connected to the end of the piston rod 121 away from the cylinder barrel 11, and a first lifting ring 22 is provided at the end of the support rod 20 away from the piston rod 121. In this way, the first lifting ring 22 can be used to connect to the axle, and the force from the outside can be transmitted to the piston rod 121 through the axle and the support rod 20 in sequence, and then the shock absorber assembly 100 can perform the shock absorption function.

[0043] It can be understood that the piston rod 121 is exposed to the external environment and has a relatively high risk of damage. By detachably connecting the support rod 20 to the end of the piston rod 121 away from the cylinder barrel 11, the detachable design of the support rod 20 can be realized, so that the shock absorber 10 has the convenience of disassembly and replacement. When overhauling the shock absorber 10, it is convenient to replace the support rod 20 alone, which can reduce the overhaul cost of the shock absorber assembly 100.

[0044] In addition, a second lifting ring 113 is provided at the end of the cylinder barrel 11 away from the piston rod 121. The second lifting ring 113 is connected with a mounting seat 114, and the mounting seat 114 can be connected to the vehicle body, so that the movement of the vehicle body can be transmitted to the shock absorber assembly 100.

[0045] In this way, the upper and lower ends of the shock absorber 10 can be connected to the vehicle body and the axle respectively. When the road surface is uneven, the axle and the vehicle body move relatively up and down, thereby driving the piston rod assembly 12 to move up and down relative to the cylinder barrel 11. The piston rod assembly 12 compresses the shock absorption medium in the cylinder barrel 11, thereby generating a damping force to attenuate the vibration caused by the spring.

[0046] Furthermore, as shown in combination with Figure 2 and Figure 3 , the support rod 20 is provided with a mounting hole 21, the inner wall of the mounting hole 21 is provided with a third thread portion, and the outer periphery of the end of the piston rod 121 away from the cylinder barrel 11 is provided with a fourth thread portion. The third thread portion is in threaded engagement with the fourth thread portion.

[0047] Specifically, by providing a third threaded portion inside the mounting hole 21 of the support rod 20, and correspondingly, providing a fourth threaded portion on the outer periphery of the end of the piston rod 121 away from the cylinder barrel 11, only by gradually screwing the end of the piston rod 121 away from the cylinder barrel 11 into the mounting hole 21 so that the third threaded portion and the fourth threaded portion are threadedly engaged with each other, the connection and fixation between the support rod 20 and the piston rod 121 can be achieved. And only by gradually screwing the piston rod 121 out of the mounting hole 21 to release the threaded engagement between the third threaded portion and the fourth threaded portion, the support rod 20 can be detached from the piston rod 121. Thus, not only can the connection stability between the support rod 20 and the piston rod 121 be improved, but also the disassembly and assembly of the support rod 20 can be made simpler and more convenient.

[0048] Combined Figures 1 - 3 As shown, the shock absorber assembly 100 may further include: an upper spring tray 30 and a lower spring tray 40. The upper spring tray 30 and the lower spring tray 40 are respectively sleeved on the outer periphery of the cylinder barrel 11 and are spaced apart in the up and down direction. A shock-absorbing spring 50 is clamped between the upper spring tray 30 and the lower spring tray 40. The upper spring tray 30 is detachably connected to the cylinder barrel 11, and / or the lower spring tray 40 is detachably connected to the support rod 20.

[0049] Specifically, by sleeving the upper spring tray 30 on the outer periphery of the cylinder barrel 11 to connect the upper spring tray 30 to the cylinder barrel 11, and sleeving the lower spring tray 40 on the outer periphery of the cylinder barrel 11 to detachably connect the lower spring tray 40 to the support rod 20, when the piston rod 121 of the shock absorber 10 moves up and down in the cylinder barrel 11, it will drive the lower spring tray 40 to approach or move away from the upper spring tray 30 in the up and down direction, realizing the compression or release of the shock-absorbing spring 50. Thus, the shock absorber 10 can work in cooperation with the shock-absorbing spring 50 to jointly undertake the tasks of supporting the vehicle body, reducing vibration, and maintaining vehicle stability.

[0050] By making the upper spring tray 30 detachably connected to the cylinder barrel 11, the detachable design of the upper spring tray 30 can be realized, so that the shock absorber 10 has the convenience of disassembly and replacement. When overhauling the shock absorber 10, it is convenient to replace the upper spring tray 30 alone, which can reduce the overhaul cost of the shock absorber assembly 100.

[0051] Moreover, by making the lower spring tray 40 detachably connected to the cylinder barrel 11, the detachable design of the lower spring tray 40 can be realized, so that the shock absorber 10 has the convenience of disassembly and replacement. When overhauling the shock absorber 10, it is convenient to replace the lower spring tray 40 alone, which can reduce the overhaul cost of the shock absorber assembly 100.

[0052] In some embodiments of the present utility model, the upper spring tray 30 is provided with a fifth threaded portion, and the outer periphery of the cylinder barrel 11 is provided with a sixth threaded portion, and the fifth threaded portion is in threaded engagement with the sixth threaded portion.

[0053] Specifically, by providing the upper spring tray 30 with a fifth threaded portion, and correspondingly, providing a sixth threaded portion on the outer periphery of the cylinder barrel 11, only by gradually screwing the upper spring tray 30 in so that the fifth threaded portion and the sixth threaded portion are in threaded engagement with each other, the connection and fixation between the upper spring tray 30 and the cylinder barrel 11 can be achieved. And only by gradually screwing out the upper spring tray 30 to release the threaded engagement between the fifth threaded portion and the sixth threaded portion, the upper spring tray 30 can be detached from the cylinder barrel 11, thereby realizing the detachable connection between the upper spring tray 30 and the cylinder barrel 11, which can not only improve the connection stability between the upper spring tray 30 and the cylinder barrel 11, but also make the disassembly and assembly of the upper spring tray 30 simpler and more convenient.

[0054] Furthermore, in some other embodiments of the present utility model, a connection sleeve 112 is sleeved on the outer periphery of the cylinder barrel 11. The connection sleeve 112 is connected to the cylinder barrel 11, and a sixth threaded portion is provided on the outer periphery of the connection sleeve 112. Specifically, a connection sleeve 112 can be provided on the outer periphery of the cylinder barrel 11 to fixedly connect the connection sleeve 112 to the cylinder barrel 11, and then a sixth threaded portion is provided on the outer periphery of the connection sleeve 112. In this way, on the premise of ensuring the detachable design of the upper spring tray 30, there is no need to directly provide a threaded portion on the outer periphery of the cylinder barrel 11, which can improve the structural stability and reliability of the cylinder barrel 11 and also make the processing and manufacturing of the cylinder barrel 11 simpler.

[0055] Combined Figures 1 - 3 As shown, the shock absorber assembly 100 may further include: a dust cover 60, the dust cover 60 is sleeved on the outer periphery of the cylinder barrel 11, the lower spring tray 40 is fixedly arranged on the outer periphery of the dust cover 60, and the dust cover 60 is detachably connected to the support rod 20.

[0056] Specifically, the dust cover 60 is sleeved on the outer periphery of the cylinder barrel 11, and the dust cover 60 is connected to the support rod 20. In this way, the piston rod 121 can drive the support rod 20 and the dust cover 60 to move simultaneously. The dust cover 60 can prevent external dust from entering the space between the cylinder barrel 11 and the piston rod 121, ensuring the normal operation of the shock absorber assembly 100.

[0057] By fixing the lower spring tray 40 on the outer periphery of the dust cover 60, for example: welding the lower spring tray 40 and the dust cover 60 together, making the lower spring tray 40 and the dust cover 60 an integrated structure, and making the dust cover 60 and the support rod 20 detachably connected, the detachable design of the dust cover 60 can be achieved, that is: the detachable design of the lower spring tray 40 can be achieved, so that the dust cover 60 and even the lower spring tray 40 can be easily replaced separately, thereby reducing the maintenance cost of the shock absorber assembly 100.

[0058] In some embodiments of the present invention, a seventh threaded portion is provided on the dust cover 60, and an eighth threaded portion is provided on the outer periphery of the support rod 20, and the seventh threaded portion is threadably matched with the eighth threaded portion.

[0059] Specifically, by providing a seventh threaded portion on the dust cover 60 and correspondingly providing an eighth threaded portion on the outer periphery of the support rod 20, it is only necessary to gradually screw in the dust cover 60 so that the seventh threaded portion and the eighth threaded portion are threadedly engaged with each other to achieve the connection and fixation between the dust cover 60 and the support rod 20, and it is only necessary to gradually screw out the dust cover 60 so as to release the threaded engagement between the seventh threaded portion and the eighth threaded portion to remove the dust cover 60 from the support rod 20, thereby achieving a detachable connection between the dust cover 60 and the support rod 20, which can not only improve the connection stability between the dust cover 60 and the support rod 20, but also make the disassembly and assembly of the dust cover 60 and even the lower spring tray 40 simpler and more convenient.

[0060] Combination Figures 1 - 3 As shown, the shock absorber assembly 100 may further include: a dust cover 70, which may be connected between the cylinder 11 and the dust cover 60, and a damping spring 50 is sleeved on the outer periphery of the dust cover 70, and the dust cover 70 is retractable in the up and down directions, thereby playing a dust-proof role without affecting the relative movement between the piston rod assembly 12 and the cylinder 11.

[0061] In addition, the piston rod assembly 12 may further include: a basic valve 122 and a limit piece 123. The basic valve 122 is connected to one end of the piston rod 121 close to the cylinder 11. The limit piece 123 is penetrated and connected to the piston rod 121, and is spaced apart from the basic valve 122 in the up and down directions. During the up and down movement of the piston rod 121, the basic valve 122 can squeeze the damping medium, and the guide seat 13 can cooperate with the limit piece 123 to limit the extreme position of the piston rod 121.

[0062] The vehicle according to the present utility model may include: the shock absorber assembly 100 described above. Specifically, the shock absorber assembly 100 of the present application has the convenience of being disassembled and replaced. By applying the shock absorber assembly 100 to the vehicle, when some special events occur during use, such as vehicle accidents, etc., resulting in a failure of the shock absorber 10, only the damaged components need to be replaced correspondingly, thereby reducing the maintenance cost, enhancing the product competitiveness of the vehicle, and improving the user experience.
