[0002] In a vehicle's chassis system, elastic elements vibrate when impacted. To improve the vehicle's ride comfort, a shock absorber is installed in parallel with the elastic element. The shock absorber consists of a piston rod, a dust cover, and a spring. The dust cover is mounted outside the piston rod, and the spring is mounted on the dust cover's outer shell. The dust cover prevents dust, stones, and other external debris from entering the shock absorber, thereby protecting the shock absorber's working components from damage and ensuring optimal operating conditions. The dust cover includes a main body with a flange extending outward at one end, where the spring abuts.

[0003] In the prior art, to prevent the spring from directly contacting the flange and damaging it, a gasket is placed between the spring and the flange. The spring abuts the flange via the gasket. This placement of the gasket between the spring and the flange complicates the assembly process of the shock absorber, requiring the gasket to be installed before the dust cover.

[0026] This application provides a dust cover for a shock absorber. Figure 1-Figure 3The dust cover 10 may include a cover body 11, an annular flange 12 and a reinforcement 13. The cover body 11 is in the shape of a bellows, and one end of the cover body 11 is connected to the annular flange 12. The cover body 11 is used to prevent external foreign matter from invading the interior of the shock absorber. The cover body 11 is set in the shape of a bellows, so that the cover body 11 can be stretched or compressed when the piston rod moves, so that the cover body 11 can move synchronously with the piston rod. The material of the annular flange 12 and the cover body 11 can be plastic or rubber, so that the dust cover 10 has good compressibility. The annular flange 12 can be integrally processed and molded with the cover body 11. The annular flange 12 is protruding toward one side of the external space of the cover body 11, and the annular flange 12 is used to contact the spring of the shock absorber, so that the spring can apply a force to the annular flange 12, thereby preventing the annular flange 12 from falling off, thereby ensuring the reliability of dustproofing. A reinforcement member 13 is disposed within the annular flange 12. The annular flange 12 covers at least a portion of the outer circumference of the reinforcement member 13. The reinforcement member 13 has a greater hardness than the annular flange 12. The annular flange 12 may cover a portion of the outer circumference of the reinforcement member 13, or may cover the entire outer circumference of the reinforcement member 13, as long as the reinforcement member 13 is integrated with the annular flange 12. The reinforcement member 13 may be made of a relatively hard plastic or metal, forming the framework of the annular flange 12, thereby enhancing the strength of the annular flange 12 and ensuring sufficient hardness and toughness at the contact point between the annular flange 12 and the spring.

[0027] The dust cover 10 provided in the present application includes an annular flange 12 and a reinforcement 13. The reinforcement 13 is provided in the annular flange 12. The annular flange 12 at least covers a part of the outer periphery of the reinforcement 13. The hardness of the reinforcement 13 is greater than the hardness of the annular flange 12. With such an arrangement, on the one hand, the reinforcement 13 is integrated into the annular flange 12, and the reinforcement 13 forms a whole with the cover body 11 and the annular flange 12, which is convenient for assembling the dust cover 10 as a whole. Compared with assembling each component separately, the assembly steps in the shock absorber assembly process are reduced, which can simplify the installation process of the shock absorber; on the other hand, the reinforcement 13 located in the annular flange 12 has a higher hardness, which can improve the strength of the annular flange 12, so that there is no need to install a gasket at the contact point between the outside of the annular flange 12 and the spring, which can further simplify the installation process of the shock absorber.

[0028] In one embodiment, if Figure 3As shown, the annular flange 12 covers a portion of the outer periphery of the reinforcement 13. A mounting groove 121 is provided on the side of the annular flange 12 facing the interior space of the cover body 11. The reinforcement 13 is embedded in the mounting groove 121, and the groove wall of the mounting groove 121 covers a portion of the outer periphery of the reinforcement 13. The reinforcement 13 and the annular flange 12 can be assembled and connected; the reinforcement 13 and the annular flange 12 can also be integrally formed, for example, using a vulcanization process to integrally form the reinforcement 13 with the annular flange 12. Providing the mounting groove 121 on the annular flange 12 can facilitate the integration of the reinforcement 13 into the annular flange 12. The mounting groove 121 is provided on the side of the annular flange 12 facing the interior space of the cover body 11, so that the opening of the mounting groove 121 faces the interior space of the cover body 11, which can prevent external dust from entering the mounting groove 121.

[0029] In one embodiment, the annular flange 12 covers the entire circumference of the reinforcement 13. The reinforcement 13 is integrally formed with the annular flange 12, embedded within the annular flange 12, and covers the entire circumference of the reinforcement 13. For example, a vulcanization process can be used to integrally form the reinforcement 13 with the annular flange 12. The reinforcement 13 is integrally formed with the annular flange 12, and the annular flange 12 covers the entire circumference of the reinforcement 13, so that the reinforcement 13 is integrated with the annular flange 12. The reinforcement 13 and the annular flange 12 are bonded to each other, which prevents the reinforcement 13 from falling off the annular flange 12.

[0030] See also Figure 4 In one embodiment, the reinforcement member 13 is a multi-segmented, separate member. Each segment of the reinforcement member 13 is annularly distributed within the annular flange 12 along the circumferential direction of the annular flange 12. The reinforcement member 13 may have two, three, or more segments. By configuring the reinforcement member 13 as a multi-segmented, separate member, each segment of the reinforcement member 13 can be independently processed and assembled into the annular flange 12. Because each segment is relatively small, the reinforcement member 13 can be easily assembled into the annular flange 12 when the two are assembled and connected.

[0031] In one embodiment, if Figure 5 As shown, the reinforcement 13 is an annular integral part. The reinforcement 13 is provided as an integral part, so that the reinforcement 13 has better integrity, which can improve the rigidity of the annular flange 12, so that the contact between the annular flange 12 and the spring has sufficient strength. The shape of the reinforcement 13 can be circular or polygonal, and the shape of the annular flange 12 can also be circular or polygonal. The shape of the reinforcement 13 can be different from the shape of the annular flange 12. In one embodiment, the shape of the reinforcement 13 is the same as the shape of the annular flange 12, which can make the thickness of the annular flange 12 wrapped around the outer periphery of the reinforcement 13 more uniform, thereby reducing the material consumption of the annular flange 12 and reducing production costs.

[0032] See also Figure 5 In one embodiment, the reinforcement member 13 is provided with a connection hole 131 extending through the reinforcement member 13 along the direction in which the cover 11 extends, and a portion of the annular flange 12 is inserted into the connection hole 131. Inserting a portion of the annular flange 12 into the connection hole 131 of the reinforcement member 13 forms an interlocking connection between the annular flange 12 and the reinforcement member 13, thereby enhancing the secure connection between the reinforcement member 13 and the annular flange 12 and preventing the reinforcement member 13 from falling off the annular flange 12.

[0033] In one embodiment, if Figure 5 As shown, the reinforcement 13 is in the form of a sheet. The reinforcement 13 being in the form of a sheet means that the size of the reinforcement 13 in the extension direction of the cover body 11 is smaller than the size of the reinforcement 13 in the extension direction perpendicular to the cover body 11. Setting the reinforcement 13 in the form of a sheet can improve the strength of the annular flange 12 while reducing the size of the reinforcement 13 in the extension direction of the cover body 11, thereby reducing the size of the shock absorber in this direction, which is conducive to the miniaturization of the shock absorber. There are multiple connecting holes 131, and the multiple connecting holes 131 are distributed at intervals along the circumferential direction of the reinforcement 13, so that the reinforcement 13 and the annular flange 12 are reliably connected in all directions. For example, the multiple connecting holes 131 can be evenly distributed along the circumferential direction of the reinforcement 13.

[0034] See also Figure 6 In one embodiment, the reinforcement member 13 is in a grid-like configuration and is provided with grid holes 132 extending through the reinforcement member 13 along the direction in which the housing 11 extends. A portion of the annular flange 12 is embedded in the grid holes 132. The grid-like configuration of the reinforcement member 13 allows the annular flange 12 to form an interlocking connection with the reinforcement member 13 due to the large number of grid holes 132 on the reinforcement member 13. This enhances the secure connection between the reinforcement member 13 and the annular flange 12, making it less likely for the reinforcement member 13 to fall off the annular flange 12.

[0035] The present application provides a shock absorber. The shock absorber includes the dust cover 10 as described above and a spring. The spring is mounted on the outside of the cover body 11 of the dust cover 10, and one end of the spring is in contact with the annular flange 12. The spring can apply a force to the annular flange 12, thereby preventing the annular flange 12 from falling off, thereby ensuring the dustproof effect. The shock absorber may also include a piston rod and a bearing. The cover body 11 is arranged outside the piston rod, and the cover body 11 can prevent external debris from entering the interior of the shock absorber, thereby protecting the working parts of the shock absorber from damage and ensuring that the shock absorber can maintain an optimal working state. One side of the annular flange 12 is in contact with the bearing, and the other side of the annular flange 12 is in contact with the end of the spring, thereby clamping the annular flange 12 between the bearing and the spring, which can prevent the annular flange 12 from falling off, thereby enhancing the airtightness of the shock absorber.

[0036] The present application provides a vehicle including the shock absorber described above. The shock absorber can be installed in the vehicle's chassis system. The shock absorber is used to reduce vibration generated by an elastic element when impacted, thereby improving the vehicle's ride smoothness and thus enhancing the user experience. The vehicle can be powered by a fuel engine or an electric motor. Other vehicle structures are not described in detail here.

Any equivalent device or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the scope of patent protection of this application.
