[0039] The following is combined with Figure 2-6 This application is described in further detail.

[0040] The embodiment of the present application discloses a sealing gasket.

[0041] Reference Figure 2 and Figure 3 The sealing gasket 1 includes a base 11 and a sealing frame 12. The base 11 is arranged in a circular sleeve shape, and an embedding groove 111 is provided on the outer side of the base 11 along its own circumference. The sealing frame 12 is made of a metal material. In this embodiment, the sealing frame 12 is made of an iron material to ensure the structural strength of the sealing frame 12. In other embodiments, the sealing frame 12 may also be made of aluminum or other metal materials, which is not limited by the present application. Specifically, the sealing frame 12 includes a sealing portion 121, which is arranged along the circumference of the base 11, that is, the sealing portion 121 is arranged in a circular ring shape and embedded in the embedding groove 111.

[0042] Among them, the outer side of the sealing part 121 abuts against the inner side of the mounting ring 3. Since the sealing part 121 is made of iron material, the sealing part 121 can always stably abut against the inner side of the mounting ring 3. Even if the base 11 ages, the sealing between the sealing gasket 1 and the mounting ring 3 can be effectively guaranteed, thereby effectively reducing the oil leakage of the automobile shock absorber after long-term use, so as to improve the quality and service life of the automobile shock absorber. At the same time, the sealing part 121 is embedded in the embedding groove 111, which can effectively improve the structural strength of the base 11, so as to improve the overall structural strength of the sealing gasket 1, and can ensure the elastic deformation amplitude of the base 11, slow down the aging rate of the base 11, and further improve the service life of the sealing gasket 1.

[0043] Reference Figure 3 In some embodiments, the sealing skeleton 12 also includes a connecting portion 122, which is arranged along the circumference of the substrate 11, so that the connecting portion 122 is arranged in a disc shape, and the connecting portion 122 is integrally connected to the inner side of the sealing portion 121 to increase the connection area between the sealing skeleton 12 and the substrate 11, thereby improving the connection strength between the sealing skeleton 12 and the substrate 11, and further improving the overall structural strength of the sealing gasket 1.

[0044] In some embodiments, the connecting portion 122 is formed by bending inward at one end of the sealing portion 121 close to the leather cup 2, that is, the connecting portion 122 is arranged at one end of the sealing portion 121 close to the leather cup 2, so that the connecting portion 122 squeezes the base 11, so that the base 11 can be more closely abutted against the leather cup 2 to ensure the sealing between the sealing gasket 1 and the leather cup 2, thereby further improving the effect of preventing oil leakage of the automobile shock absorber.

[0045] The implementation principle of this embodiment is: since the sealing part 121 is made of iron material, the sealing part 121 can always stably abut against the inner side of the mounting ring 3, and even if the base 11 ages, the sealing performance between the sealing gasket 1 and the mounting ring 3 can be effectively guaranteed, thereby effectively reducing the oil leakage of the automobile shock absorber after long-term use, so as to improve the quality and service life of the automobile shock absorber. At the same time, the sealing part 121 is embedded in the embedding groove 111, which can effectively improve the structural strength of the base 11, so as to improve the overall structural strength of the sealing gasket 1, and can ensure the elastic deformation amplitude of the base 11, slow down the aging speed of the base 11, and further improve the service life of the sealing gasket 1.

[0046] The application embodiment also discloses a vehicle shock absorber.

[0047] Reference Figure 4The automobile shock absorber includes a leather cup 2, a mounting ring 3 and a sealing gasket 1 as described in the above embodiment, wherein the leather cup 2 is fixedly connected to the lower end of the mounting ring 3, the base 11 is fixedly connected to the mounting ring 3 and the upper end protrudes from the mounting ring 3, and the lower end of the base 11 abuts against the leather cup 2, and the outer side of the base 11 and the outer side of the sealing portion 121 abut against the inner side of the mounting ring 3 to ensure the sealing between the sealing gasket 1 and the leather cup 2 and the mounting ring 3, and even if the base 11 ages, the sealing between the sealing gasket 1 and the mounting ring 3 can be effectively guaranteed, thereby effectively reducing the oil leakage of the automobile shock absorber after long-term use.

[0048] Reference Figure 4 and Figure 5 In some embodiments, the automobile shock absorber further includes a support arm 4, which is detachably connected to the upper end of the base 11.

[0052] In some embodiments, the automobile shock absorber also includes a rubber protective sleeve 8, which is sleeved on one end of the support arm 4 that is currently located between the mounting bracket 7 and the mounting ring 3, and can minimize the support arm 4 from being crushed by the mounting bracket 7 or the mounting ring 3. At the same time, the rubber protective sleeve 8 has a certain elasticity, and can also make the support arm 4 more tightly limited between the mounting bracket 7 and the mounting ring 3, and can also play a certain shock-absorbing role.

[0053] In some embodiments, the upper side of the rubber protective sleeve 8 is protruded to form two positioning protrusions 81, and the two positioning protrusions 81 are arranged at intervals. The upper end of the mounting bracket 7 is provided with two positioning grooves 71, and the two positioning protrusions 81 are respectively positioned and limited in the two positioning grooves 71 to achieve the positioning and installation of the rubber protective sleeve 8 and the mounting bracket 7, and can improve the stability of the installation of the rubber protective sleeve 8. In addition, the upper side of the rubber protective sleeve 8 is protruded to form a plurality of abutting protrusions 82 to abut against the mounting bracket 7, thereby increasing the friction between the rubber protective sleeve 8 and the mounting bracket 7, and further improving the stability of the installation of the support arm 4.
