Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0027] The shock absorber assembly and vehicle provided by this utility model will be described in detail below with reference to the embodiments.
[0028] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6 , Figure 1 This is a schematic diagram of the structure of an embodiment of the vibration damper assembly of this application; Figure 2 yes Figure 1 A schematic diagram of the cross-section of AA is shown below; Figure 3 yes Figure 2 An enlarged schematic diagram of B is shown below; Figure 4 This is a schematic diagram of the dust cover in the shock absorber assembly of this application; Figure 5 yes Figure 4 A schematic diagram of the cross-section of DD is shown below; Figure 6 yes Figure 5The diagram shown is an enlarged view of E. This application provides a vibration damper assembly. The vibration damper assembly 10 includes a vibration damper 11, a support 12, a buffer member 13, and a dust cover 14. The vibration damper 11 includes a piston rod 111. The support 12 is connected to the piston rod 111. The buffer member 13 is sleeved on the outer periphery of the piston rod 111. The dust cover 14 is sleeved on at least a portion of the vibration damper 11. The dust cover 14 includes a first end 14a and a second end 14b disposed opposite to each other. A buffer portion 141 is provided on the end face of the first end 14a. The buffer portion 141 abuts between the inner end face of the support 12 and the end face of the buffer member 13.
[0029] The shock absorber assembly 10 is connected between the wheel (not shown in the figure) and the vehicle body (not shown in the figure). For example, the piston rod 111 of the shock absorber 11 in the shock absorber assembly 10 can be detachably or fixedly connected to the support 12. The support 12 can be, but is not limited to, an upper support. A buffer 13 is fitted onto and connected to the outer periphery of the piston rod 111. The buffer 13 is a buffer block (not shown in the figure). The buffer block can limit the travel of the shock absorber 11, absorb shocks, and improve user comfort, etc.
[0030] The dust cover 14 may be partially or completely fitted around the outer periphery of the vibration damper 11. In this embodiment, the dust cover 14 is fitted around the outer periphery of the end of the vibration damper 11 near the support 12. The first end 14a of the dust cover 14 is connected to the support 12. The second end 14b of the dust cover 14 is fitted around the vibration damper 11.
[0031] A buffer portion 141 is provided on the end face of the first end 14a. The buffer portion 141 abuts between the inner end face of the support 12 and the end face of the buffer member 13, that is, the buffer portion 141 is connected between the buffer member 13 and the support 12.
[0032] During the up-and-down movement of the wheel, the buffer part 141 can play a buffering role, which can reduce the impact noise when the buffer part 13 contacts the support 12, thereby improving the user experience.
[0033] In one specific embodiment, a plurality of protrusions (not shown in the figure) are provided on the end face of the buffer member 13 facing the inner end face of the support 12. The protrusions contact the inner end face of the support 12. The multiple protrusions can also reduce the impact noise when the buffer member 13 contacts the support 12.
[0034] In some embodiments, the support 12 is provided with a support groove 121. The buffer 13 is at least partially located within the support groove 121. The buffer portion 141 abuts against the bottom wall of the support groove 121 and the end face of the buffer 13 facing the bottom wall.
[0035] The support groove 121 is groove-shaped and can accommodate at least part of the buffer 13 and at least part of the dust cover 14. The buffer part 141 abuts against the bottom wall of the support groove 121 and the end face of the buffer 13 facing the bottom wall.
[0036] Confining at least a portion of the buffer 13 and at least a portion of the dust cover 14 within the support groove 121 can improve the stability of the buffer 13 and the dust cover 14 when installed on the support 12.
[0037] Please continue reading. Figures 1 to 6 In some embodiments, a first protrusion 142 is provided on the outer periphery of the first end 14a. The first protrusion 142 abuts against the inner sidewall of the support groove 121.
[0038] The first protrusion 142 is raised. The first protrusion 142 can abut against the inner wall of the support groove 121. When the vehicle turns or runs on a tortuous road, the buffer 13 swings with the shock absorber 11. Because the dust cover 14 is provided with the first protrusion 142, the buffer 13 can abut against the inner wall of the support groove 121 through the first protrusion 142. The first protrusion 142 plays a buffering role, which can reduce friction and impact noise between the buffer 13 and the support 12, thereby improving the user experience.
[0039] In one specific embodiment, the inner sidewall of the first protrusion 142 and the outer peripheral surface of the buffer 13 are spaced apart, which can reduce abnormal noise between the first protrusion 142 and the buffer 13, thereby improving the user experience.
[0040] Specifically, the first protrusion 142 can be integral or segmented. When the first protrusion 142 is integral, it surrounds the outer peripheral surface of the first end 14a. Alternatively, when the first protrusion 142 is segmented, the number of first protrusions 142 can be two, three, or more than four, with multiple first protrusions 142 spaced apart and surrounding the outer peripheral surface of the first end 14a.
[0041] In some embodiments, a dustproof recess 143 is provided on the outer periphery of the first end 14a. A buffer recess 131 is provided on the outer periphery of the buffer member 13. The dustproof recess 143 is embedded in the buffer recess 131.
[0042] The dustproof recess 143 is recessed so that the sidewall of the dust cover 14 is recessed towards the center of the dust cover 14. The buffer recess 131 is recessed so that the sidewall of the buffer member 13 is recessed towards the center of the buffer member 13. The buffer recess 131 provides an installation position for the dustproof recess 143. The dustproof recess 143 and the buffer recess 131 are shaped to match so that the dustproof recess 143 can be fitted into the buffer recess 131. For example, both the dustproof recess 143 and the buffer recess 131 may be arc-shaped.
[0043] The outer periphery of the first end 14a and the outer periphery of the buffer member 13 work together through the dustproof recess 143 and the buffer recess 131 to improve the stability of the installation between the dust cover 14 and the buffer member 13, thereby reducing the risk of the dust cover 14 and the like coming off.
[0044] In some embodiments, the dustproof recess 143 and the buffer recess 131 are both located within the support groove 121.
[0045] The dustproof recess 143 and the buffer recess 131 are both located in the support groove 121, which further improves the stability of the dust cover 14 and the buffer 13 installed on the support 12 and further reduces the risk of the dust cover 14 and the buffer 13 coming off.
[0046] Please see Figure 7 and Figure 8 , Figure 7 yes Figure 2 An enlarged schematic diagram of C is shown below; Figure 8 yes Figure 5 An enlarged schematic diagram of F is shown. (Combined with...) Figures 1 to 6 In some embodiments, the end of the second end 14b is provided with an expansion portion 144. The sidewall of the expansion portion 144 is arc-shaped along the first end 14a toward the second end 14b and away from the outer periphery of the damper 11. The inner sidewall of the expansion portion 144 is spaced apart from the outer periphery of the damper 11.
[0047] The expansion portion 144 is detachably or fixedly connected to the end of the second end 14b. In this embodiment, the expansion portion 144 is integrally formed and connected to the end of the second end 14b. The sidewall of the expansion portion 144 is arc-shaped in the direction from the first end 14a to the second end 14b and gradually away from the outer periphery of the damper 11. That is, the expansion portion 144 can be, but is not limited to, a frustum-shaped drum or an arc-shaped frustum.
[0048] The inner wall of the expansion portion 144 is spaced apart from the outer peripheral surface of the damper 11. As the side wall of the expansion portion 144 is gradually moved away from the outer peripheral direction of the damper 11, the distance between the inner wall of the expansion portion 144 and the outer peripheral surface of the damper 11 increases in the direction from the first end 14a to the second end 14b.
[0049] By providing an expansion portion 144 at the end of the second end 14b, the risk of wear on the periphery of the dust cover 14 end wear damper 11 can be reduced.
[0050] In some embodiments, at least one second protrusion 145 is provided on the outer periphery of the second end 14b.
[0051] The second protrusion 145 is detachably or fixedly connected to the outer periphery of the second end 14b. In this embodiment, the second protrusion 145 is integrally formed on the outer periphery of the second end 14b. The number of second protrusions 145 may be, but is not limited to, one, two, or more than three. In this embodiment, there are two second protrusions 145. The aforementioned second protrusions 145 may be arranged in a ring shape.
[0052] By providing at least one second protrusion 145 on the outer periphery of the second end 14b, the rigidity of the second end 14b of the dust cover 14 can be improved, thereby reducing the risk of deformation of the dust cover 14; it can also reduce interference and abnormal noise between the dust cover 14 and the outer cylinder 113 of the vibration damper 11.
[0053] In some embodiments, the dust cover 14 is a plastic dust cover (not shown in the figure). The plastic dust cover is made of plastic and has a certain degree of rigidity. The material of the second protrusion 145 may be the same as that of the dust cover 14.
[0054] Specifically, the second protrusion 145 can be integral or segmented. When the second protrusion 145 is integral, it surrounds the outer peripheral surface of the second end 14b. Alternatively, when the second protrusion 145 is segmented, the number of second protrusions 145 can be two, three, or more than four, with multiple second protrusions 145 spaced apart and surrounding the outer peripheral surface of the second end 14b.
[0055] Please continue reading. Figures 1 to 8 In some embodiments, the shock absorber 11 further includes a dust cover 112 and an outer cylinder 113. The dust cover 112 is fitted onto the outer cylinder 113. The end of the dust cover 112 near the second end 14b is located inside the dust cover 14. The inner sidewall of the dust cover 14 is spaced apart from the outer peripheral surface of the dust cover 112.
[0056] The dust cover 112 is cylindrical and can cover at least part of the outer cylinder 113 of the shock absorber 11, thereby reducing the entry of dust and other impurities into the shock absorber 11 and thus improving the service life of the shock absorber assembly 10.
[0057] The outer cylinder 113 is cylindrical and can accommodate at least part of the piston rod 111. The end of the dust cover 112 near the second end 14b is located inside the dust cover 14, which can reduce the entry of dust and other impurities into the shock absorber 11 and further improve the service life of the shock absorber assembly 10.
[0058] During the process of installing at least part of the vibration damper 11 on the dust cover 14, the inner wall of the dust cover 14 and the outer peripheral surface of the dust cover 112 are spaced apart, which can reduce the interference of the dust cover 14 with the movement of the dust cover 112, thereby reducing the occurrence of abnormal noise and improving the user experience.
[0059] In some embodiments, the dust cover 14 includes an extension 146. Along the direction from the first end 14a to the second end 14b, the radial distance between the inner sidewall of the extension 146 and the outer peripheral surface of the dust cover 112 and the radial distance between the inner sidewall of the extension 146 and the outer peripheral surface of the outer cylinder 113 gradually increases.
[0060] In particular, along the direction from the first end 14a to the second end 14b, the radial distance between the inner wall of the extension 146 and the outer peripheral surface of the dust cover 112 gradually increases, which can reduce the interference of the end of the extension 146 near the second end 14b with the movement of the dust cover 112, thereby reducing the occurrence of abnormal noise and improving the user experience.
[0061] Along the direction from the first end 14a to the second end 14b, the radial distance between the inner wall of the extension 146 and the outer peripheral surface of the outer cylinder 113 gradually increases, which can reduce the interference of the end of the extension 146 near the second end 14b with the movement of the outer cylinder 113, thereby reducing the occurrence of abnormal noise and improving the user experience.
[0062] In one specific embodiment, the outer cylinder 113 is cylindrical, the extension 146 is flared, and the radial distance between the inner wall of the extension 146 and the outer peripheral surface of the outer cylinder 113 gradually increases. The dust cover 112 is cylindrical, the extension 146 is flared, and the radial distance between the inner wall of the extension 146 and the outer peripheral surface of the dust cover 112 gradually increases.
[0063] In some embodiments, the second protrusion 145 is circumferentially disposed on the outer peripheral surface of the extension 146 and near the second end 14b. The outwardly expanding portion 144 is disposed at the end position of the second end 14b of the dust cover 14.
[0064] Please continue reading. Figures 1 to 8 This application provides a vehicle. The vehicle includes a shock absorber assembly 10.
[0065] It should be noted that the shock absorber assembly 10 in this embodiment is the same as the shock absorber assembly 10 described in the above embodiments, and will not be repeated here.
[0066] By using the aforementioned shock absorber assembly 10, the vehicle can reduce the impact noise when the buffer 13 contacts the support 12, thereby improving the user experience.
