[0037] The following refers to Figures 1-5 Describe the shock absorber end cap 1 according to an embodiment of the present utility model. When the shock absorber end cap 1 contacts the buffer body 4 of the shock absorber, the buffer structure provided on the end cap portion 12 can be in pressing contact with the buffer body 4 of the shock absorber, and the design of the buffer structure makes the contact position between the two not prone to lateral slip, which is beneficial to reducing frictional noise, reducing the overall noise of the shock absorber, improving the noise performance of the shock absorber assembly 100, and enhancing the user experience.

[0038] As Figures 1-5As shown, the shock absorber blind cover 1 according to an embodiment of the present utility model includes a sleeve portion 11 and an end cover portion 12. Among them, it should be noted that the shock absorber assembly 100 includes an oil storage cylinder 2 and a piston rod 3. One end of the piston rod 3 extends into the oil storage cylinder 2 and is slidably engaged with the oil storage cylinder 2. The other end of the movable rod extends outside the oil storage cylinder 2, and a buffer body 4 is provided outside the other end of the piston rod 3. The buffer body 4 is made of an elastic material. The shock absorber blind cover 1 is sleeved outside the oil storage cylinder 2, and the end cover portion 12 is located at one end of the oil storage cylinder 2 and is spaced apart from the buffer body 4 and distributed oppositely. When the shock absorber is applied to a vehicle, one of the piston rod 3 and the oil storage cylinder 2 is relatively fixed to the vehicle body and the other is relatively fixed to the wheel. Furthermore, when the vehicle body moves relative to the wheel, the piston rod 3 moves relative to the oil storage cylinder 2, so that the shock absorber blind cover 1 repeatedly presses against the buffer body 4 to play a buffering role.

[0039] The sleeve portion 11 forms a sleeve cavity 111, and the sleeve cavity 111 extends along the axial direction of the sleeve portion 11. When the sleeve portion 11 is sleeved outside the oil storage cylinder 2, one end of the oil storage cylinder 2 is received in the sleeve cavity 111. Among them, as Figure 1 shown, a clamping protrusion 112 and a limiting abutting portion 113 are provided outside the sleeve portion 11. It should be noted that a dust cover is also provided outside the oil storage cylinder 2. The clamping protrusion 112 can be clamped and connected to the dust cover, and the limiting abutting portion 113 forms a supporting surface for supporting and cooperating with the dust cover.

[0040] The end cover portion 12 is connected to the end of the sleeve portion 11. A through hole 121 is formed in the middle of the end cover portion 12. As Figure 5 shown, the end cover portion 12 is connected to one end of the sleeve portion 11 close to the buffer body 4, and the aperture of the through hole 121 is smaller than the inner diameter of the sleeve cavity 111. The through hole 121 is used for passing through the piston rod 3. In this way, when the shock absorber blind cover 1 is installed on the shock absorber assembly 100, the sleeve portion 11 is sleeved outside the oil storage cylinder 2, the end cover portion 12 is located at the end of the oil storage cylinder 2 and is axially limited and cooperated with the oil storage cylinder 2. The piston rod 3 passes through the through hole 121 of the end cover portion 12 and can move in the through hole 121. Thus, when the piston rod 3 moves relative to the oil storage cylinder 2, the side surface of the end cover portion 12 facing away from the sleeve portion 11 can buffer and press against the buffer body 4.

[0041] Among them, the end cover portion 12 forms a buffer structure on the side surface facing away from the sleeve portion 11 for pressing and cooperating with the buffer body 4 of the shock absorber. The buffer structure includes multiple groups of buffer ribs 123. The multiple groups of buffer ribs 123 are sequentially distributed along the circumferential direction of the through hole 121. Each group of buffer ribs 123 is multiple, and the multiple buffer ribs 123 in each group are sequentially distributed from the inside to the outside around the same center.

[0042] That is to say, the end cover part 12 is in pressing contact with the buffer body 4 through the buffer structure. Specifically, multiple groups of buffer ribs 123 can be in pressing contact with the buffer body 4 simultaneously, which helps to increase the contact friction force between the damper blanking cover 1 and the buffer body 4, making it difficult for the damper blanking cover 1 and the buffer body 4 to slip laterally when in contact, improving the stability of the buffering effect. Moreover, the extending directions of multiple groups of buffer ribs 123 are around the corresponding centers, that is, the extending directions of each group of buffer ribs 123 are different, so as to produce different friction effects for multiple groups of buffer ribs 123, further improving the reliability of the contact buffering between the damper blanking cover 1 and the buffer body 4. Thus, the frictional noise caused by the adhesion of hydraulic oil during lateral slip can be reduced.

[0043] In addition, multiple groups of buffer ribs 123 are distributed by extending around their respective centers, which enables multiple groups of buffer ribs 123 to form a cross distribution when extending, and the buffer grooves 124 formed between adjacent two buffer ribs 123 are also staggered with other buffer grooves 124, so as to effectively suppress the vibration noise generated by surface-to-surface contact during the impact process. At the same time, an exhaust port 122 is provided between adjacent two groups of buffer ribs 123, and the buffer grooves 124 extend along with the extension of the buffer ribs 123. Part of the buffer grooves 124 are open grooves extending to the edge of the end cover part 12, and part of the buffer grooves 124 extend to the exhaust port 122, or another part of the buffer grooves 124 extend to the through hole 121. That is, when the buffer body 4 is in contact with the end cover part 12, the buffer grooves 124 will not form a closed cavity, which can well avoid the noise caused by the exhaust of the closed cavity, further improving the noise performance.

[0044] For the damper blanking cover 1 according to the embodiment of the present invention, by providing multiple groups of buffer ribs 123 distributed around their respective centers on the end cover part 12, a large frictional force can be formed when the damper blanking cover 1 and the buffer body 4 are in buffer pressing contact, reducing the situation of lateral slip between the damper blanking cover 1 and the buffer body 4, improving the buffer stability, reducing the frictional noise during lateral slip, and when the buffer body 4 is in contact with the end cover part 12, the space between adjacent buffer ribs 123 will not form a closed cavity, which can well avoid the noise caused by the exhaust of the closed cavity and improve the noise performance.

[0045] In some embodiments, the same center of each group of multiple buffer ribs 123 is located at the center circle. Part of the center circle is located inside the through hole 121 and the other part is located outside the through hole 121. Among them, the center circle can be the circle where the innermost buffer rib 123 is located. In this way, the buffer ribs 123 can be all arc-shaped ribs and will not form a closed circular rib, thereby avoiding the formation of a closed cavity when the end cover part 12 is in pressing contact with the buffer body 4 and preventing the situation of exhaust noise generated by the closed cavity.

[0046] Thus, a plurality of buffer ribs 123 in each group can be arranged in sequence from the inner side to the outer side of the end cover portion 12. Specifically, as Figures 1-3 shown, the extension lengths of the plurality of buffer ribs 123 in each group are set to gradually increase from the inside to the outside. For example, each buffer rib 123 is configured as an arc, and the radii of the plurality of buffer ribs 123 gradually increase from the inside to the outside, thereby forming a regular arrangement form on the side surface of the end cover portion 12. As Figure 3 shown, the buffer ribs 123 are distributed in four groups, and the four groups of buffer ribs 123 are evenly distributed in the circumferential direction of the end cover portion 12. Thus, when the end cover portion 12 is in pressing contact with the buffer body 4, the forces at various positions in the circumferential direction of the end cover portion 12 are relatively balanced, further avoiding the situation that the end cover portion 12 laterally slides relative to the buffer body 4 and improving the structural stability.

[0047] In some embodiments, at least one pair of buffer ribs 123 in the plurality of buffer ribs 123 of two adjacent groups are directly opposite in the circumferential direction of the end cover portion 12 and are separated by the exhaust port 122. That is, in the plurality of buffer ribs 123 of two adjacent groups, one pair of buffer ribs 123 can be set to be directly opposite, or two pairs, three pairs or even more pairs of buffer ribs 123 can be set to be directly opposite, so that the multiple groups of buffer ribs 123 are independent of each other. When the buffer ribs 123 are in contact with the buffer body 4, the directly opposite buffer ribs 123 are located on the same circle, making the friction forces between the buffer ribs 123 on this circle and the buffer body 4 more concentrated, which is more conducive to reducing the lateral sliding between the buffer body 4 and the end cover portion 12.

[0048] Specifically, as Figure 3 shown, both ends of a part of the buffer ribs 123 located in the innermost side among the plurality of buffer ribs 123 extend to the edge of the through hole 121, so that the buffer groove 124 formed between the buffer ribs 123 of this part communicates with the through hole 121. In addition, both ends of a part of the buffer ribs 123 located on the outer side among the plurality of buffer ribs 123 are directly opposite to the buffer ribs 123 of an adjacent group, so that the circumferentially directly opposite buffer ribs 123 are located on the same circle, which is conducive to increasing the overall length of the buffer ribs 123 on the same circle and increasing the friction force.

[0049] In some embodiments, the number of buffer ribs 123 in each group is the same, and the multiple buffer ribs 123 in adjacent two groups are symmetrically distributed. That is, a symmetry line is formed at the connection position of the buffer ribs 123 in adjacent two groups, namely the exhaust port 122, and the two groups of buffer ribs 123 are symmetrically distributed with respect to this symmetry line. In this way, the distribution modes of multiple groups of buffer ribs 123 can be set to be the same. Therefore, when the end cover part 12 is formed, multiple groups of buffer ribs 123 can be formed in the same way on the side surface of the end cover part 12, so that it is not necessary to form each group of buffer ribs 123 separately, greatly reducing the forming difficulty of the buffer ribs 123 and reducing the forming cost of the end cover part 12.

[0050] Specifically, as Figure 3 shown in, four groups of buffer ribs 123 are evenly distributed in the circumferential direction of the end cover part 12, and the arrangement mode and extension length of the buffer ribs 123 in each group are the same. Therefore, the force at the four corner positions of the end cover part 12 in, such as Figure 3 can be relatively balanced, ensuring that the frictional forces between the buffer body 4 and the end cover part 12 at various positions in the circumferential direction are relatively balanced, and avoiding the situation of sliding towards one side.

[0051] In some embodiments, the central angles corresponding to the extension lengths of multiple groups of buffer ribs 123 in the circumferential direction of the end cover part 12 are the same. In this way, the spaces occupied by multiple groups of buffer ribs 123 in the circumferential direction of the end cover part 12 can be relatively balanced. For example, if the buffer ribs 123 are N groups, and the central angle corresponding to each group of buffer ribs 123 is 360° / N. Specifically, as Figure 3 shown in, the buffer ribs 123 are 4 groups, and the central angle corresponding to each group of buffer ribs 123 is 90°, ensuring that the frictional forces between the buffer body 4 and the end cover part 12 at various positions in the circumferential direction are relatively balanced, and avoiding the situation of sliding towards one side.

[0052] In some embodiments, the buffer ribs 123 are configured to protrude from the side surface of the end cover part 12 facing away from the sleeve part 11. That is, the buffer ribs 123 can be configured as strip-shaped ribs, and the cross-section of the buffer ribs 123 can be configured as a rectangle, a trapezoid or other shapes.

[0053] Further, the width of the buffer ribs 123 can be configured to gradually decrease along the direction away from the sleeve part 11. As Figure 4 shown in, the width of the buffer ribs 123 is set to gradually decrease from top to bottom, so that the bottom of the buffer ribs 123 is more stable. In this way, when the buffer body 4 is in pressing contact with the buffer ribs 123, the buffer ribs 123 are less likely to deform under greater pressure, and the greater the pressure on the buffer ribs 123, the greater the frictional force between the buffer ribs 123 and the buffer body 4. At the same time, the inclined surface of the buffer ribs 123 is conducive to the downward flow of the oil liquid, so that the oil liquid at the end cover part 12 can flow into the buffer groove 124, realizing the function of storing and collecting the oil liquid.

[0054] In some embodiments, the cross-section of the buffer rib 123 is configured as a trapezoidal cross-section, that is, the width of the top side of the buffer rib 123 is smaller than the width of the bottom side. When the buffer body 4 is in pressing fit with the buffer rib 123, the top side of the buffer rib 123 is in pressing fit with the buffer body 4, that is, the buffer rib 123 and the buffer body 4 are in surface contact, thereby ensuring the contact friction force between the end cover portion 12 and the buffer body 4 and reducing lateral slip.

[0055] In a further embodiment, the width of the top side of the trapezoidal cross-section is L1, and it satisfies: 0.1 mm ≤ L1 ≤ 0.2 mm. For example, the width of the top side is set to 0.11 mm, 0.12 mm, 0.13 mm, 0.14 mm, 0.15 mm, 0.16 mm, 0.17 mm, 0.18 mm, 0.19 mm, or other parameter values within this range. Thus, setting the width of the top side of the buffer rib 123 to be greater than or equal to 0.1 mm can ensure a relatively large contact area between the buffer rib 123 and the buffer body 4 and guarantee the friction force between the two. At the same time, setting the width of the top side of the buffer rib 123 to be less than or equal to 0.2 mm can make the impact area between the buffer rib 123 and the buffer body 4 smaller, avoid too large an impact area between the two, generate excessive impact noise, and improve the noise performance.

[0056] Moreover, in some embodiments, the height difference between the top side and the bottom side of the trapezoidal cross-section is L2, that is, the height of the trapezoid is L2, and it satisfies: 0.5 mm ≤ L2 ≤ 0.7 mm. For example, the height difference between the top side and the bottom side of the trapezoidal cross-section is set to 0.51 mm, 0.52 mm, 0.53 mm, 0.54 mm, 0.55 mm, 0.56 mm, 0.57 mm, 0.58 mm, 0.59 mm, 0.61 mm, 0.62 mm, 0.63 mm, 0.64 mm, 0.65 mm, 0.66 mm, 0.67 mm, 0.68 mm, 0.69 mm, or other parameter values within this range. Thus, setting the height of the buffer rib 123 to be greater than or equal to 0.5 mm can ensure a relatively large buffer distance when the buffer rib 123 contacts the buffer body 4 and achieve a certain amount of vibration buffering. At the same time, setting the height of the buffer rib 123 to be less than or equal to 0.7 mm can make the stability of the buffer rib 123 better, avoid the situation of tilting and distortion due to the excessive height of the buffer rib 123, and improve the stability of the buffer rib 123.

[0057] In some embodiments, the shape of the trapezoidal cross section is an isosceles trapezoid, and the inclination angle of the waist of the trapezoidal cross section relative to the base is a, that is, the two base angles of the trapezoidal cross section are α, and satisfy: 35°≤α≤55°, such as setting the base angle α to 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, 50°, 51°, 52°, 53°, 54°, especially when the base angle is set to 45°, the height and width of the isosceles trapezoid are more balanced, which can make the structure of the buffer rib 123 more stable, thereby ensuring the stability of the buffer rib 123 when subjected to force.

[0058] In some embodiments, the distance between two adjacent buffer ribs 123 in each group of multiple buffer ribs 123 is L3, and satisfies: 1mm≤L3≤2mm, that is, the distance between the bottom sides of the two trapezoidal cross-sections is set to L3, that is, the bottom width of the buffer groove 124 is L3, such as setting L3 to 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, thereby, setting the width between the two buffer ribs 123 to be greater than or equal to 1mm, so that the arrangement of the buffer ribs 123 can be relatively dispersed, avoiding the buffer ribs 123 being too dense and resulting in a large number of them, causing excessive buffering noise. At the same time, setting the width between the two buffer ribs 123 to be less than or equal to 2mm can avoid the buffer ribs 123 being too dispersed, avoiding the number of buffer ribs 123 being too small, ensuring the friction between the buffer ribs 123 and the buffer body 4, and reducing lateral slippage.

[0059] The utility model also provides a shock absorber assembly 100 .

[0060] According to the shock absorber assembly 100 of the embodiment of the utility model, including the shock absorber cover 1 of any of the above-mentioned embodiments, a plurality of groups of buffer ribs 123 respectively distributed around the center of each circle are arranged on the end cover portion 12, so that a larger friction force can be formed when the shock absorber cover 1 and the buffer body 4 are buffered and pressed, thereby reducing the lateral slippage of the shock absorber cover 1 and the buffer body 4, improving the buffering stability, and reducing the friction noise during lateral slippage. Moreover, when the buffer body 4 contacts the end cover portion 12, the space between adjacent buffer ribs 123 will not form a closed cavity, which can well avoid the noise of exhaust from the closed cavity and improve the noise performance.

[0061] The utility model also provides a shock absorber assembly 100 .

By providing this shock absorber assembly 100, the noise generated by the shock absorber assembly 100 in the vehicle can be made smaller, and in particular, the noise transmitted into the vehicle interior space can be effectively reduced, which is conducive to improving the comfort of the occupants in the vehicle door space and enhancing the user experience.
