[0024] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will make further detailed description to the utility model in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0025] In order to effectively illustrate the utility model example, the following will make detailed description to the application example in combination with the drawings.

[0026] Referring to Figures 1 to 3 As shown in the relevant embodiment schematic diagram of a guide assembly structure with oil storage tank, the application discloses a guide assembly structure with oil storage tank, which comprises an oil seal body 1 and a guide body 2, the oil seal body 1 is matched with a cover and arranged on the guide body 2, so as to realize the sealing of oil liquid in the oil storage cylinder 24 in the guide body 2, after the assembly of the oil seal body 1 and the guide body 2, the rubber deformation at the oil seal lip 12 of the oil seal body 1 and the slope 21 of the guide body 2 are matched to rely on the oil seal deformation pressure to play a sealing role.

[0027] In the specific implementation process, as Figure 2 As shown in the relevant embodiment schematic diagram of a guide assembly structure with oil storage tank, the application discloses a guide assembly structure with oil storage tank, which comprises an oil seal body 1 and a guide body 2, the oil seal body 1 is matched with a cover and arranged on the guide body 2, so as to realize the sealing of oil liquid in the oil storage cylinder 24 in the guide body 2, after the assembly of the oil seal body 1 and the guide body 2, the rubber deformation at the oil seal lip 12 of the oil seal body 1 and the slope 21 of the guide body 2 are matched to rely on the oil seal deformation pressure to play a sealing role. Figure 1 As shown in the relevant embodiment schematic diagram of a guide assembly structure with oil storage tank, the application discloses a guide assembly structure with oil storage tank, which comprises an oil seal body 1 and a guide body 2, the oil seal body 1 is matched with a cover and arranged on the guide body 2, so as to realize the sealing of oil liquid in the oil storage cylinder 24 in the guide body 2, after the assembly of the oil seal body 1 and the guide body 2, the rubber deformation at the oil seal lip 12 of the oil seal body 1 and the slope 21 of the guide body 2 are matched to rely on the oil seal deformation pressure to play a sealing role.

[0028] In the specific implementation process, by designing the oil storage tank 23 at the bottom of the guide body 2 to store oil liquid, after the assembly of the oil seal body 1 and the guide body 2, the rubber deformation at the oil seal lip 12 and the slope 21 on the oil storage tank 23 are matched to rely on the deformation pressure of the oil seal lip 12 to play a sealing role.

[0029] Of course, in the specific implementation process, the guide body 2 is provided with a slope 21, the oil seal lip 12 is sealed with the slope 21, and the slope 21 and the guide body 2 form a tapered cavity as an oil storage groove 23. The guide body 2 is provided with a drain hole 22, and the drain hole 22 is arranged on one side of the oil storage groove 23. The drain hole 22 is used to communicate the oil storage groove 23 and an oil storage cylinder 24, and the height of the drain hole 22 is higher than the position where the oil seal lip 12 and the slope 21 are matched, and the height is not limited, which can be higher than 1-5 mm and the like. Of course, the height of the drain hole 22 is higher than the bottom height of the oil storage groove 23. The purpose is that the connecting channel formed between the oil storage groove 23 and the oil storage cylinder 24 is not directly communicated, but is communicated by being higher than the bottom height of the oil storage groove 23. In this way, the oil seal lip 12 is avoided from being directly opened by the gas and entering the oil storage cylinder 24 when the gas pressure of the shock absorber is inflated. However, by opening the oil storage groove 23 with a certain depth at the position of the guide body 2 in the embodiment of the present application, the oil liquid overflows the oil seal lip 12, so that the gas in the oil storage cylinder is less likely to leak. In addition, the guide body 2 is provided with the drain hole 21 to communicate the oil storage groove 23 and the oil storage cylinder 24, and the height of the drain hole 21 is higher than the oil storage groove 23, so that a certain amount of oil liquid can be stored in the oil storage groove 23. When the oil liquid is too much, it will flow back to the oil storage cylinder 24 from the drain hole 21, so that the oil liquid stored in the oil storage groove 23 can effectively ensure the sealing of the guide body 2.

[0030] Of course, on the basis of the above embodiment, the inclination of the slope 21 of the guide body 2 in the guide assembly structure with an oil storage groove disclosed by the present application can be generally set to 0.5-1.2, and preferably the inclination of the slope 21 is 1. That is to say, the position where the slope 21 is arranged can still form a certain space (such as shown in the figure) at the bottom of the oil storage groove 23 after the oil seal lip 12 is assembled with the slope 21, so that a certain amount of oil liquid can be stored, thereby further improving the sealing of the guide, and prolonging the service life of the shock absorber and making the damping force of the shock absorber more stable. Figure 3

[0031] Of course, in the specific implementation process, the structure of the guide body and the oil seal is not limited to the above structure disclosed by the present application, but the specific structure disclosed by the present application is the main structural component for solving the technical problems of the present application. For other related structures, please refer to the related guide and oil seal structures of the prior art, which will not be described in detail here.

[0032] The above only describes the preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.​
