DETAILED DESCRIPTION

[0037] 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.

[0038] The spring tray assembly 10 of the embodiment of the present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] Reference Figure 2 , Figure 3 , Figure 6 and Figure 7 The spring tray assembly 10 according to the embodiment of the present application is described. The spring tray assembly 10 is applied to the shock absorber 100, and the spring tray 11 is used to install the shock absorber spring 20 to meet the assembly requirements of the shock absorber spring 20 in the shock absorber 100 and improve the applicability of the shock absorber 100. Among them, by adjusting the position of the shock absorber spring 20 in the shock absorber 100, the size adjustment of the shock absorber 100 in the axial direction (i.e., the height position adjustment of the shock absorber 100 in the vehicle 1000) can be achieved, so that the shock absorber 100 can achieve the body height adjustment of the vehicle 1000 to improve the passability of the vehicle 1000.

[0040] Reference Figure 2 and Figure 3 As shown, the spring tray assembly 10 includes: a tray 11, a cylinder 12 and a piston 3. The tray 11 is used to connect with the damping spring 20, so as to be fixedly matched with one end of the damping spring 20 through the tray 11. The cylinder 12 is sleeved on the tray 11, and the cylinder 12 and the tray 11 are fixedly connected. The cylinder 12 and the tray 11 define a driving chamber 101 with one end open along a first direction, and the cylinder 12 is provided with a communication port 121 connected with the driving chamber 101, and the driving medium can enter the driving chamber 101 through the communication port 121, or the driving medium can be discharged from the driving chamber 101 to the outside of the cylinder 12 through the communication port 121.

[0041] Combination Figure 2 , Figure 3 and Figure 4As shown, the piston 3 is connected to the cylinder 30 of the shock absorber 100, and at least part of the piston 3 is arranged in the driving chamber 101, and the piston 3 can reciprocate along the first direction relative to the cylinder 12 and the tray 11. That is, when the driving medium is injected into the driving chamber 101 through the connecting port 121, the driving medium can drive the piston 3 to extend outward from the driving chamber 101 along the first direction; when the gravity of the vehicle body is fed back to the tray 11, the piston 3 extends into the inside of the driving chamber 101 along the first direction and presses out the driving medium in the driving chamber 101.

[0042] In the present application, the spring tray assembly 10 is fixedly connected to the cylinder 30 of the shock absorber 100 through the piston 3, the tray 11 is used to connect to one end of the shock absorbing spring 20, and the tray 11 and the cylinder 12 can move synchronously relative to the piston 3. Therefore, when the piston 3 extends from the driving chamber 101 along the first direction or retracts toward the inner side of the driving chamber 101 along the first direction, the distance between the connection between the piston 3 and the cylinder 12 and the connection between the tray 11 and the shock absorbing spring 20 in the first direction can be adjusted, so that the height adjustment of the shock absorber 100 can be achieved through the spring tray assembly 10, that is, the height position of the shock absorber 100 supporting the vehicle body is adjusted, so that the shock absorber 100 can lift or lower the vehicle body height.

[0043] Reference Figure 2 When the piston 3 abuts against the tray 11, the size of the spring tray assembly 10 in the first direction is the smallest. Figure 3 After the driving chamber 101 is filled with the driving medium, as the driving medium is further injected, the pressure in the driving chamber 101 gradually increases, so that the piston 3 has a movement tendency to extend outward from the driving chamber 101 along the first direction. As the piston 3 extends from the driving chamber 101, the size of the spring tray assembly 10 in the first direction gradually increases, so that the distance between the connection between the piston 3 and the cylinder 30 and the position where the shock-absorbing spring 20 is installed on the tray 11 in the first direction increases. The lifting action of the shock absorber 100 can be achieved by adjusting the position of the shock-absorbing spring 20 relative to the cylinder 30.

[0044] It should be noted that in the related art, a damping spring is provided in the shock absorber, and the damping spring is fixed by a bracket welded on the cylinder of the shock absorber, or integrated on the control arm, which cannot realize the active adjustment of the vehicle height, thus resulting in a small ground clearance of the vehicle, affecting the vehicle's passability. Taking a sports car as an example, when the sports car is in a climbing condition (such as: driving out of the basement), passing through a speed bump, etc., the chassis of the vehicle is at risk of being scratched by the road surface or the speed bump.

[0045] In the present application, the position of the shock-absorbing spring 20 relative to the cylinder 30 of the shock absorber 100 is adjustable through the spring tray assembly 10, so that the position of the piston 3 relative to the tray 11 and the cylinder 12 can be adjusted as needed, so as to further adjust the position of the shock-absorbing spring 20 relative to the cylinder 30 to realize the lifting or lowering adjustment function of the shock absorber 100, thereby improving the passability of the vehicle 1000.

[0046] like Figure 2 and Figure 3 As shown, in some embodiments of the present application, the tray 11 is provided with a mounting surface 1121, and the mounting surface 1121 is used to mount the damping spring 20, so as to fix one end of the damping spring 20 to the tray 11. The connection method between the tray 11 and the damping spring 20 is not specifically limited here, such as welding, etc.

[0047] like Figure 2 and Figure 3 As shown, in some embodiments of the present application, the cylinder 12 is provided with an exhaust hole 122 communicating with the driving chamber 101 , and the connection between the exhaust hole 122 and the driving chamber 101 is arranged adjacent to the closed end of the driving chamber 101 in the first direction.

[0048] When air enters the driving chamber 101, the gas in the driving chamber 101 can be discharged to the outside through the exhaust hole 122 to ensure the driving effect of the driving medium on the piston 3. It can be understood that the above-mentioned driving medium is a liquid medium (such as hydraulic oil, etc.). When the liquid medium is first injected into the driving chamber 101, or when the liquid medium in the driving chamber 101 flows back to the liquid supply system, there will be gas in the driving chamber 101. As the liquid medium is injected into the driving chamber 101, the gas in the driving chamber 101 can be discharged to the outside through the exhaust hole 122.

[0049] Furthermore, since the piston 3 moves relative to the drive chamber 101 along the first direction, the exhaust hole 122 is arranged near the closed end of the drive chamber 101 in the first direction, so that the gas in the drive chamber 101 can be fully discharged to improve the gas discharge effect in the drive chamber 101.

[0050] In a further embodiment of the present application, the spring tray assembly 10 also includes an exhaust valve (not shown in the figure), which is arranged in the exhaust hole 122, and the exhaust valve is used to allow the gas in the drive chamber 101 to be discharged unidirectionally to the outside of the cylinder 12, so as to improve the sealing performance at the exhaust hole 122 through the exhaust valve to prevent the gas or pollutants (such as dust, etc.) outside the cylinder 12 from entering the drive chamber 101 through the exhaust hole 122 and causing contamination (such as contamination of the driving medium).

[0051] like Figure 2 and Figure 3As shown, in some embodiments of the present application, the tray 11 includes: a cylinder 111 and a mounting seat 112, the cylinder 111 can be sleeved on the cylinder 30, and the cylinder 111 can move along a first direction relative to the cylinder 30 to adjust the position of the damping spring 20 relative to the cylinder 30.

[0052] Further, the mounting seat 112 is disposed at one end of the barrel 111 in the first direction, and the mounting seat 112 has a mounting surface 1121 , and the mounting surface 1121 is used to mount the damping spring 20 so as to be connected and matched with the damping spring 20 through the mounting seat 112 .

[0053] In a further embodiment of the present application, the mounting seat 112 is integrally provided with the cylinder portion 111 , which can reduce the difficulty of processing the tray 11 while ensuring the structural strength of the tray 11 .

[0054] Reference Figure 2 and Figure 3 As shown, the cylinder 12 is sleeved on the mounting seat 112 along a first direction from a side of the mounting seat 112 away from the mounting surface 1121 , and the mounting seat 112 is formed with a positioning groove 1122 , which is used to position and cooperate with the cylinder 12 to improve the connection reliability between the tray 11 and the cylinder 12 .

[0055] In some embodiments of the present application, the mounting seat 112 is formed with a step portion 1123 , which is arranged along the outer peripheral wall of the protruding cylinder portion 111 in the radial direction, and the step portion 1123 is arranged opposite to the piston 3 in the first direction.

[0056] Reference Figure 2 and Figure 3 The tray 11, the cylinder 12 and the piston 3 together define a driving chamber 101. By arranging the step portion 1123 relative to the end of the piston 3, the pressure generated by the driving medium can act on the end of the piston 3 to drive the piston 3 to extend outward from the driving chamber 101.

[0057] Reference Figure 2 It can be understood that when the piston 3 abuts against the step portion 1123, a space structure for the driving medium to flow in is reserved between the end of the piston 3 and the step portion 1123 (e.g., a groove or other structure is formed at the end of the piston 3), so that the driving medium can flow into between the end face of the piston 3 and the step portion 1123, so that the pressure generated by the driving medium can act on the end face of the piston 3, thereby driving the piston 3 to move relative to the tray 11 and the cylinder 12. Among them, the groove structure can also be formed on the step portion 1123, that is, the space structure can satisfy the need for the driving medium to flow in and act the driving force on the end face of the piston 3 in the first direction.

[0058] like Figure 2 and Figure 3 As shown, in some embodiments of the present application, the cylinder 12 is provided with a support flange 123 , which extends radially inward from the inner wall of the cylinder 12 , and the piston 3 is clamped between the outer peripheral wall of the barrel 111 and the support flange 123 .

[0059] It can be understood that the support flange 123 is arranged opposite to the partial step portion 1123 in the first direction, so that the support flange 123 can be supported between the piston 3 and the inner wall of the cylinder 12 in the radial direction, and the inner wall of the cylinder 12 and the piston 3 are spaced apart in the radial direction to reserve a certain gap between the cylinder 12 and the piston 3 to form a space for the driving medium to flow into.

[0060] It should be noted that if the inner wall of the cylinder 12 is arranged in close contact with the piston 3, the driving force generated by the driving medium at the communication port 121 formed on the cylinder 12 is not convenient to act on the end of the piston 3. In the present application, by setting the inner wall of the cylinder 12 and the piston 3 apart, a liquid storage space for the driving medium to be filled is reserved between the cylinder 12 and the piston 3, so as to facilitate the injection of the driving medium during the adjustment process of the spring tray assembly 10.

[0061] In some embodiments of the present application, a limiting portion 31 is provided at the end of the piston 3, and the limiting portion 31 is used to cooperate with the supporting flange 123 to prevent the piston 3 from escaping from the driving chamber 101, thereby improving the assembly reliability of the piston 3 in the spring tray assembly 10.

[0062] In a specific embodiment of the present application, the limiting portion 31 can be configured as a limiting protrusion, which extends from the outer peripheral wall of the piston 3 along the radial direction toward the inner wall of the cylinder 12. At the same time, in the first direction, the limiting protrusion is arranged opposite to at least part of the support flange 123, the limiting protrusion is located in the driving cavity 101, and the limiting protrusion can be abutted against the side surface of the support flange 123 opposite to the step portion 1123 to prevent the piston 3 from falling out.

[0063] like Figure 2 As shown, in some embodiments of the present application, the spring tray assembly 10 also includes a first seal 61, which is disposed between the piston 3 and the tray 11, and is used to form a seal between the piston 3 and the tray 11 to improve the sealing between the piston 3 and the tray 11 and prevent the driving medium in the driving chamber 101 from leaking out of the gap between the piston 3 and the tray 11.

[0064] Reference Figure 2 The first sealing member 61 is disposed between the tray 11 (eg, the barrel portion 111 of the tray 11 ) and the inner circumferential wall of the piston 3 to achieve radial sealing between the piston 3 and the tray 11 .

[0065] Specifically, a groove structure that is concave inward in the radial direction (i.e., away from the side of the piston 3) can be formed on the outer wall of the cylinder 111, and the first seal 61 can be embedded in the groove structure, and the first seal 61 is interference-fitted with the inner circumferential wall of the piston 3. Among them, multiple first seals 61 can be provided, and the multiple first seals 61 are arranged at intervals along the first direction to improve the sealing effect between the tray 11 and the piston 3 by forming multiple sealings.

[0066] like Figure 2 As shown, in some embodiments of the present application, the spring tray assembly 10 also includes a second seal 62, which is disposed between the piston 3 and the cylinder 12, and the second seal 62 is used to form a seal between the piston 3 and the cylinder 12 to improve the sealing between the piston 3 and the cylinder 12 and prevent the driving medium in the driving chamber 101 from leaking from the gap between the piston 3 and the cylinder 12.

[0067] Reference Figure 2 The second sealing member 62 is disposed between the cylinder barrel 12 (eg, at the supporting flange 123 of the cylinder barrel 12 ) and the outer peripheral wall of the piston 3 to achieve radial sealing between the piston 3 and the cylinder barrel 12 .

[0068] Specifically, a groove structure that is concave outward in the radial direction (i.e., away from the side of the piston 3) can be formed on the inner wall of the support flange 123, and the second seal 62 can be embedded in the groove structure, and the second seal 62 is interference-fitted with the outer peripheral wall of the piston 3. Among them, multiple second seals 62 can be provided, and the multiple second seals 62 are arranged at intervals along the first direction to improve the sealing effect between the cylinder 12 and the piston 3 by forming multiple seals.

[0069] like Figure 2 As shown, in some embodiments of the present application, the spring tray assembly 10 also includes a third seal 63, which is disposed between the cylinder 12 and the tray 11, and the third seal 63 is used to form a seal between the cylinder 12 and the tray 11 to improve the sealing between the tray 11 and the cylinder 12 and prevent the driving medium in the driving chamber 101 from leaking out of the gap between the tray 11 and the cylinder 12.

[0070] It should be noted that the sealing structure in the spring tray assembly 10 includes at least one of the first sealing member 61, the second sealing member 62 and the third sealing member 63. Figure 2 The spring tray assembly 10 is preferably provided with a first seal 61 , a second seal 62 and a third seal 63 at the same time, so as to enhance the sealing effect at the driving cavity 101 , prevent leakage of the driving medium, and improve the driving reliability and stability of the spring tray assembly 10 .

[0071] In the description of the present application, it should be understood that the terms "center", "length", "width", "thickness", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0072] Reference Figure 4-Figure 7 The shock absorber 100 according to the embodiment of the present application is described, and the shock absorber 100 includes: the above-mentioned spring tray assembly 10, the cylinder 30 and the damping spring 20, the damping spring 20 is sleeved on the cylinder 30, the spring tray assembly 10 is connected to one end of the damping spring 20, and the spring tray assembly 10 is sleeved on the cylinder 30. Among them, the spring tray assembly 10 is arranged near the lower end of the cylinder 30.

[0073] Specifically, the spring tray assembly 10 is installed on the cylinder 30, and the spring tray assembly 10 is used to install the shock-absorbing spring 20. The position of the shock-absorbing spring 20 relative to the cylinder 30 can be adjusted through the spring tray assembly 10, so that the shock absorber 100 can realize the height adjustment function of the vehicle body through the position of the shock-absorbing spring 20 in the shock absorber 100.

[0074] Among them, by increasing the size of the spring tray assembly 10 in the first direction (which is also the axial direction of the shock absorber 100), the shock absorber 100 can lift the vehicle body; by reducing the size of the spring tray assembly 10 in the first direction (which is also the axial direction of the shock absorber 100), the shock absorber 100 can lower the vehicle body.

[0075] The shock absorber 100 in the present application has a simple adjustment method and good stability, and can improve the passability of the vehicle 1000.

[0076] like Figure 2 As shown, in some embodiments of the present application, the spring tray assembly 10 also includes a mounting gasket 4, which is arranged at one end of the piston 3 located outside the driving chamber 101, and the mounting gasket 4 can form a mounting structure at the end of the piston 3 to facilitate the installation of other components (such as: seat structure, adjusting nut 5, etc.) through the mounting structure.

[0077] It can be understood that the provision of the mounting gasket 4 can increase the mounting area of ​​the piston 3 at the end, and can meet the assembly requirements of the end of the piston 3 .

[0078] In a further embodiment of the present application, the spring tray assembly 10 also includes an adjusting nut 5, which is connected to the mounting gasket 4, and the cylinder 30 is provided with an external thread 301, and the adjusting nut 5 is sleeved outside the cylinder 30 and threadably matched with the external thread 301 of the cylinder 30.

[0079] The external thread 301 may be directly formed on the outer peripheral wall of the cylinder 30 , or may be formed on a sleeve component, and the sleeve component is fixedly matched with the cylinder 30 by sleeve arrangement.

[0080] It can be understood that by adjusting the threaded cooperation between the nut 5 and the cylinder 30, the position of the adjusting nut 5 relative to the cylinder 30 in the first direction can be adjusted, so that the position of the spring tray assembly 10 relative to the cylinder 30 in the first direction can be adjusted, further increasing the adjustment range of the damping spring 20 relative to the cylinder 30 in the first direction.

[0081] Combination Figure 4 and Figure 6 , under the action of the spring tray assembly 10, the maximum adjustment distance of the damping spring 20 relative to the cylinder 30 in the first direction is L2; ​​combined Figure 4 and Figure 5 Under the action of the adjusting nut 5, the maximum adjustment distance of the damping spring 20 relative to the cylinder 30 in the first direction is L1; combined Figure 4 and Figure 7 Under the joint action of the adjusting nut 5 and the spring tray 11, the maximum adjustment distance of the damping spring 20 relative to the cylinder 30 in the first direction is L1+L2.

[0082] Therefore, by providing the adjusting nut 5 , the adjustment range of the damping spring 20 can be further increased, which helps to improve the trafficability of the vehicle 1000 .

[0083] In some embodiments of the present application, the shock absorber 100 also includes a shock absorbing pad 7, which is disposed on the tray 11 and arranged between one end of the shock absorbing spring 20 and the mounting surface 1121 of the tray 11, so as to buffer the vibration between the shock absorbing spring 20 and the mounting seat 112 through the shock absorbing pad 7.

[0084] like Figure 3 and Figure 4 As shown, in some embodiments of the present application, the shock absorber 100 is further provided with an upper tray 40, and the upper tray 40 is used to be connected to the vehicle body.

[0085] Reference Figure 8 and Fig. 9 The shock absorber 100 in the present application can be applied to a suspension system.

[0086] In the suspension system, a shock absorber 100 and a fluid supply device are provided, the fluid supply device including a fluid storage portion 201 and a driving portion 202, the fluid storage portion 201 is used to store a driving medium, and the driving portion 202 is used to pump the driving medium to the driving chamber 101, so as to realize the lifting function of the shock absorber 100 by delivering the driving medium to the spring tray assembly 10 in the shock absorber 100. In the condition of lowering the height of the vehicle body, the driving medium needs to be recovered, and the driving medium can be recovered to the fluid supply device.
