Moreover, the terms “comprise”, “contain” or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such a process, method, article or device. Without more limitations, the elements defined by the statement “comprise” do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0027] Please refer to Figures 1 to 4In a first aspect, the new embodiment provides an elastic structure 100 for an upper support assembly 10 of a shock absorber 20. The elastic structure 100 includes a first connecting portion 111, a second connecting portion 112, and a third connecting portion 113. The second connecting portion 112 is arranged around the outer periphery of the first connecting portion 111, and the third connecting portion 113 is arranged around the outer periphery of the second connecting portion 112. The upper support assembly 10 includes an inner sleeve 300 and an outer sleeve 400. The first connecting portion 111 is used to connect the inner sleeve 300 of the upper support assembly 10, and the third connecting portion 113 is used to connect the outer sleeve 400 of the upper support assembly 10. The second connecting portion 112 includes a connecting body and a blocking portion 120. The connecting body is provided with at least one hole structure K1, and the hole structure K1 extends in the thickness direction of the elastic structure 100. The blocking portion 120 is arranged in the hole structure K1, and the ratio Z of the thickness H1 of the blocking portion 120 to the thickness H2 of the connecting body in the thickness direction satisfies 0.2≤Z<1.

[0028] It should be noted that the thickness direction of the elastic structure 100 can be the axial direction of the shock absorber 20 or the height direction of the vehicle. For the sake of convenience, the thickness direction of the elastic structure 100 is referred to as the thickness direction.

[0029] The elastic structure 100 is connected with the shock absorber 20 and used to buffer the vibration of the shock absorber 20. The material of the elastic structure 100 can be various, for example, the material of the elastic structure 100 can include rubber, and of course, the material of the elastic structure 100 can also include other elastic materials, which are not limited in the embodiment. The elastic structure 100 includes the first connecting portion 111, the second connecting portion 112, and the third connecting portion 113 connected in sequence. The first connecting portion 111 is connected with the inner sleeve 300 of the upper support assembly 10, and can be connected with the shock absorber 20 through the inner sleeve 300, thereby buffering the vibration of the shock absorber 20. Optionally, the inner sleeve 300 can be arranged around the outer periphery of the connecting rod of the shock absorber 20, and the first connecting portion 111 can be wrapped around the outer periphery of the inner sleeve 300, thereby increasing the connection area of the inner sleeve 300 and the shock absorber 20 and the connection area of the first connecting portion 111 and the inner sleeve 300, and improving the connection reliability.

[0030] The second connecting portion 112 is arranged on the outer circumferential side of the first connecting portion 111 along the circumferential direction of the first connecting portion 111. The second connecting portion 112 can include a connecting body and a blocking portion 120, and the connecting body is provided with a hole structure K1 which can or can not penetrate the connecting body in the thickness direction, and the present embodiment does not limit this. When the hole structure K1 penetrates the connecting body, the depth of the hole structure K1 in the thickness direction is equal to the thickness of the connecting body. By providing the hole structure K1 on the connecting body, the stiffness of the elastic structure 100 can be adjusted to meet the stiffness requirement of the upper support assembly 10. It should be noted that in the present embodiment, the stiffness of the upper support assembly 10 is adjusted by providing the hole structure K1 to meet the target stiffness requirement, specifically, the upper support assembly 10 can maintain a certain degree of stability while buffering the vibration of the shock absorber 20.

[0031] The number of hole structures K1 can be one or more, and when the number of hole structures K1 is more, the plurality of hole structures K1 can be distributed at intervals along the circumferential direction of the elastic structure 100. The shape of the hole structure K1 can be various, for example, the hole structure K1 can be a circular hole, or a waist-shaped hole, and the hole structure K1 can also be other regular or irregular shaped hole structures, and the present embodiment does not limit this.

[0032] The third connecting portion 113 is arranged on the outer circumferential side of the second connecting portion 112 along the circumferential direction of the second connecting portion 112, and the third connecting portion 113 is used to connect with the outer bushing 400, and it can be connected to the outer shell 200 of the upper support assembly 10 through the outer bushing 400. Optionally, the outer bushing 400 can be arranged on the outer circumferential side of the third connecting portion 113 to increase the connection area and improve the connection reliability.

[0033] In some optional embodiments, the first connecting portion 111 and the second connecting portion 112 can be an integrally formed structure, and / or the second connecting portion 112 and the third connecting portion 113 can be an integrally formed structure. When the two components are integrally formed, on the one hand, the connection reliability of the two components can be improved, and on the other hand, the preparation process of the elastic structure 100 can be simplified, and the preparation difficulty can be reduced.

[0034] It can be understood that the elastic structure 100 can be formed by extrusion of upper and lower molds. In the related art, it is difficult for the upper and lower molds to completely close at the hole structure K1, that is, there can be a small gap between the upper and lower molds at the hole structure K1, and the elastic material remains in the aforementioned gap, thereby forming a film inside the hole structure K1. In actual working conditions, the shock absorber 20 usually generates airflow when vibrating, and the airflow is extremely easy to break the film in the hole structure K1. The broken film forms burrs and flash inside the hole structure K1, which in turn causes abnormal noise or vibration in the upper support assembly 10 under the continuous influence of the airflow.

[0035] In view of this, the new embodiment sets the plugging part 120 in the hole structure K1 and reasonably sets the relative relationship between the thickness H1 of the plugging part 120 and the thickness H2 of the connecting body. On the one hand, the plugging part 120 can resist the airflow to avoid abnormal noise caused by burrs and flash in the hole structure K1. On the other hand, the structure can adjust the rigidity of the elastic structure 100, so that the upper support assembly 10 can adapt to the buffering requirements under various working conditions.

[0036] It should be noted that in the new embodiment, the ratio of the thickness H1 of the plugging part 120 to the thickness H2 of the connecting body in the thickness direction of the elastic structure 100 can be greater than or equal to 0.2 and less than or equal to 1, for example, the ratio can be 0.2, 0.3, 0.5, 0.6, 0.7, etc.

[0037] The plugging part 120 can be an integral structure with the connecting body, and the materials thereof can be the same or different. For example, by changing the closing gap of the upper and lower molds, the hole structure K1 and the plugging part 120 in the hole structure K1 can be formed at the corresponding position at the same time when the connecting body is prepared. Alternatively, the plugging part 120 can be a separate component, and the plugging part 120 can be formed in the hole structure K1 after the preparation of the connecting body, which is not limited in the embodiment.

[0038] Please refer to Figure 5 In some optional embodiments, the first connecting part 111 can be wrapped around the inner liner 300 from the outside of the inner liner 300. At this time, the first connecting part 111 can include a first sub-part 1111 and a second sub-part 1112 connected to each other. The first sub-part 1111 can be arranged on the opposite sides of the inner liner 300 along the width direction of the elastic structure 100 and on the outer circumferential side of the inner liner 300 away from the shock absorber 20 along the width direction. The second sub-part 1112 can be arranged on the inner side of the inner liner 300 close to the shock absorber 20 along the width direction, thereby further increasing the connection area between the first connecting part 111 and the inner liner 300 and improving the connection reliability therebetween.

[0039] It should be noted that the width direction of the elastic structure 100 is perpendicular to the thickness direction of the elastic structure 100. The width direction of the elastic structure 100 can be any one of the plurality of radial directions of the shock absorber 20, and can also be the length direction or the width direction of the vehicle. In the present embodiment, the width direction of the elastic structure 100 is referred to as the width direction for convenience.

[0040] Please continue to refer to Figure 5 In some optional embodiments, in the above width direction, the width L1 of the first sub-portion 1111 can be greater than or equal to 9 mm and less than or equal to 13 mm, and preferably the width L1 of the first sub-portion 1111 can be 11 mm. By reasonably setting the width L1 of the first sub-portion 1111, the stiffness requirement of the elastic structure 100 in the width direction can be met, and the performance of the elastic structure 100 and the upper support assembly 10 can be improved.

[0041] Please continue to refer to Figure 5 In some optional embodiments, in the above width direction, the width L2 of the second sub-portion 1112 can be greater than or equal to 1.05 mm and less than or equal to 1.55 mm, and preferably the width L2 of the first sub-portion 1111 can be 1.3 mm. By reasonably setting the width L2 of the second sub-portion 1112, the stiffness requirement of the elastic structure 100 in the width direction can be met, and the performance of the elastic structure 100 and the upper support assembly 10 can be improved.

[0042] Please continue to refer to Figure 5 In some optional embodiments, in the above width direction, the width L3 of the second connecting portion 112 can be greater than or equal to 2.5 mm and less than or equal to 3.5 mm, and preferably the width L3 of the second connecting portion 112 can be 3 mm. By reasonably setting the width L3 of the second connecting portion 112, the stiffness requirement of the elastic structure 100 in the width direction can be met, and the performance of the elastic structure 100 and the upper support assembly 10 can be improved.

[0043] In some embodiments, the material of the blocking portion 120 is the same as that of the second connecting portion 112, so as to improve the bonding effect between the blocking portion 120 and the inner wall of the hole structure K1, improve the connection reliability of the two, and further improve the resistance of the blocking portion 120 to the airflow.

[0044] In other embodiments of the present application, the material of the blocking portion 120 can also be different from that of the second connecting portion 112, and in actual application, the material of the blocking portion 120 can be flexibly selected according to the actual situation of the elastic structure 100.

[0045] In some embodiments, the blocking part 120 and the connecting body are formed in an integrated structure. The blocking part 120 is fixedly connected with the connecting body to improve the reliability and stability of the blocking part 120.

[0046] In addition, the blocking part 120 can be formed by the same process as the connecting body, for example, the blocking part 120 and the connecting body can be formed by extrusion through the upper and lower molds at the same time, which can simplify the manufacturing process of the elastic structure 100, reduce the manufacturing difficulty, and improve the production efficiency.

[0047] In some embodiments, the blocking part 120 is a separate component, and the hole structure K1 is a through hole. The blocking part 120 is configured to block a part of the through hole in the depth direction of the through hole. At this time, the blocking part 120 can be prepared after the connecting body is formed, so that the upper and lower molds used to manufacture the elastic structure 100 do not need to be changed, which helps to reduce the production cost of the elastic structure 100.

[0048] Optionally, when the blocking part 120 is a separate component, the blocking part 120 can be detachably connected with the connecting body to facilitate replacement, thereby helping to improve the service life of the elastic structure 100.

[0049] In some embodiments, the ratio Z of the thickness H1 of the blocking part 120 to the thickness H2 of the connecting body satisfies: 0.2≤Z≤0.5, for example, the ratio can be 0.2, 0.3, 0.35, 0.4, 0.5, etc. On the basis of guaranteeing the rigidity requirement of the elastic structure 100, the structural strength of the blocking part 120 is improved, so that the blocking part 120 has the ability to resist airflow impact and reduces the risk of being broken by airflow.

[0050] Please continue to refer to Figure 4 In some embodiments, the thickness H1 of the blocking part 120 satisfies: 2.5 millimeters≤H1≤4 millimeters, for example, the thickness H1 of the blocking part 120 can be 2.5 millimeters, 3 millimeters, 3.5 millimeters, 3.7 millimeters, 4 millimeters, etc. The thickness H1 of the blocking part 120 is reasonably set, so as to improve the structural strength of the blocking part 120 on the basis of guaranteeing the rigidity requirement of the elastic structure 100.

[0051] It can be known that when the thickness H1 of the blocking part 120 is greater than or equal to 2.5 millimeters and less than or equal to 4 millimeters, the thickness H2 of the connecting body can be greater than or equal to 8 millimeters and less than or equal to 12 millimeters, and preferably the thickness H2 of the connecting body can be 10 millimeters. By reasonably setting the thickness of the connecting body, the depth of the hole structure K1 is reasonably set, which helps to meet the rigidity requirement of the elastic structure 100 in the thickness direction and improve the elastic buffering capacity of the elastic structure 100.

[0052] Please continue to refer to Figure 2In some embodiments, the number of hole structures K1 is multiple, and the multiple hole structures K1 are uniformly distributed along the circumference of the elastic structure 100. The number of blocking parts 120 is multiple, and the multiple blocking parts 120 are configured to block the hole structures K1 one by one.

[0053] In these embodiments, the number of hole structures K1 is set to be multiple, which helps to flexibly adjust the rigidity of the elastic structure 100 to meet the rigidity requirements of the upper support assembly 10 in the width direction and the thickness direction. The multiple hole structures K1 are uniformly distributed along the circumference of the elastic structure 100, which helps to make the gravity distribution of each part of the elastic structure 100 in the circumferential direction uniform, thereby improving the stability of the elastic structure 100 in the upper support assembly 10. Moreover, the multiple blocking parts 120 block the hole structures K1 one by one, and by resisting the airflow generated by the vibration of the shock absorber 20 in the corresponding hole structure K1 through the multiple blocking parts 120, the burrs and flash in each hole structure K1 can be avoided, further reducing the risk of abnormal noise or vibration in the upper support assembly 10.

[0054] It should be noted that the number of hole structures K1 can be reasonably selected according to actual conditions. Preferably, the number of hole structures K1 can be 8, and the 8 hole structures K1 are uniformly distributed along the circumference, and the central axes of the adjacent two hole structures K1 can form an included angle of approximately 45° to meet the rigidity requirements of the upper support assembly 10.

[0055] Please continue to refer to Figure 2 In some embodiments, in a plane perpendicular to the thickness direction, the hole structure K1 is projected along the thickness direction in a waist shape, which helps to improve the stress dispersion capability of the elastic structure 100 and enhance the rigidity of the elastic structure 100.

[0056] Please continue to refer to Figure 5 In some embodiments, the second connecting part 112 is located between the first connecting part 111 and the third connecting part 113, and a groove K2 is formed on the upper and lower sides of the second connecting part 112 along the thickness direction. The groove K2 is located between the first connecting part 111 and the third connecting part 113, and the groove K2 is arranged along the circumference of the first connecting part 111.

[0057] Specifically, in the thickness direction, the thickness of the second connecting part 112 is less than the thickness of the first connecting part 111 and the thickness of the third connecting part 113, so that the opposite sides of the second connecting part 112 can be recessed inward relative to the opposite sides of the first connecting part 111 and the third connecting part 113. At this time, the first connecting part 111, the second connecting part 112, and the third connecting part 113 can enclose the groove K2 on the opposite sides of the second connecting part 112 along the thickness direction, and the groove K2 can extend along the circumference of the first connecting part 111.

[0058] In the new embodiment, the grooves K2 are formed on the opposite sides of the second connecting portion 112 in the thickness direction, and the rigidity of the elastic structure 100 can be further adjusted by reasonably setting the shape and size of the grooves K2 to meet the rigidity requirement of the upper support assembly 10.

[0059] In a second aspect, the new embodiment provides an upper support assembly 10 comprising the elastic structure 100 of any of the above. The upper support assembly 10 provided by the new embodiment has the technical effects of the technical solutions of the elastic structure 100 in any of the above embodiments, and the explanations of the structures and terms that are the same or similar to the above embodiments will not be repeated here.

[0060] Please continue to refer to Figure 1 and Figure 4 In some embodiments, the upper support assembly 10 comprises a shell 200, an inner sleeve 300, an outer sleeve 400, and the elastic structure 100 described above. The shell 200 is provided with a receiving cavity and a through hole communicating with the receiving cavity, and the through hole is used for passing the shock absorber 20; the inner sleeve 300 is arranged in the receiving cavity and is used for connecting with the shock absorber 20; the elastic structure 100 is arranged in the receiving cavity, and in the elastic structure 100, the first connecting portion 111 of the elastic structure 100 is arranged on the outer circumferential side of the inner sleeve 300 along the circumferential direction of the inner sleeve 300; the outer sleeve 400 is arranged in the receiving cavity and is arranged on the outer circumferential side of the elastic structure 100 along the circumferential direction, and the outer sleeve 400 is connected with the third connecting portion 113 of the elastic structure 100.

[0061] In some embodiments, the upper support assembly 10 further comprises an inner gasket 500, which is annular and arranged between the inner sleeve 300 and the shock absorber 20 to connect the inner sleeve 300 and the shock absorber 20.

[0062] Please refer to Figure 6 Optionally, the outer circumferential side of the inner gasket 500 away from the shock absorber 20 (i.e. the side of the inner gasket 500 close to the inner sleeve 300) is provided with at least two limiting grooves K3, and correspondingly, the inner side of the inner sleeve 300 towards the shock absorber 20 is provided with at least two limiting portions, and the limiting portions of the inner sleeve 300 are one-to-one clamped in the limiting grooves K3 of the inner gasket 500, so as to limit the inner gasket 500 and the inner sleeve 300 along the circumferential direction of the shock absorber 20, thereby reducing the risk of relative rotation of the two.

[0063] It should be noted that the number of limiting grooves K3 can be flexibly set according to actual conditions. For example, the number of limiting grooves K3 can be two, and the two limiting grooves K3 are located on the opposite sides of the inner gasket 500. Alternatively, as Figure 6 shown, the number of limiting grooves K3 can be four, and the four limiting grooves K3 are evenly distributed along the circumferential direction of the inner gasket 500 to improve the stability of the shock absorber 20.

[0064] The size of the limiting groove K3 can be reasonably set according to the size of the inner gasket 500. Exemplarily, when the diameter of the inner gasket 500 is 42 mm, the minimum size of the axis of the inner gasket 500 to the limiting groove K3 can be 16 mm, at this time, the maximum depth of the limiting groove K3 can be 5 mm, and the width of the limiting groove K3 can be approximately 12 mm, and the size of the limiting portion is matched with the size of the limiting groove K3. It can be known that by reasonably setting the size of the limiting groove K3, the reliability and stability of the inner gasket 500 and the inner bush 300 when the inner gasket 500 and the inner bush 300 are clamped through the limiting groove K3 and the limiting portion can be improved on the basis of ensuring the structural strength of the inner gasket 500.

The vehicle provided by the embodiment of the present application has the technical effects of the technical solutions of the upper support assembly 10 in any of the above embodiments, and the same or corresponding structures and explanations of terms are not described here.

[0066] It can be known that the vehicle can further comprise a shock absorber 20, and the shock absorber 20 can extend into the accommodating cavity through the via hole on the shell 200 of the upper support assembly 10 to be connected with the upper support assembly 10.

[0067] The above is only a specific implementation of the present application, and those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working process of the above-described system, module and unit can refer to the corresponding process in the foregoing method embodiments, which will not be described here.
