Description

Technical Field

[0001] This utility model belongs to the technical field of shock absorber outer cylinder, and more specifically, it relates to a high-sealing shock absorber outer cylinder. Background Technology

[0002] During the operation of a shock absorber, the outer cylinder, inner cylinder, piston, and other components work together to absorb vibrations caused by road bumps or potholes by changing the flow path of the liquid and the diameter of the damping holes. This damping principle enables the shock absorber to effectively improve the comfort and stability of the vehicle. The outer cylinder provides necessary protection for the inner cylinder, preventing it from being damaged by the external environment, such as corrosion and wear. This helps to extend the service life of the shock absorber and maintain its stable performance.

[0003] In the prior art, patent application document "CN208764219U" discloses a "shock absorber outer cylinder"; it includes an outer cylinder body, the inner cavity of which is provided axially with a first mounting hole for installing a support sleeve and a second mounting hole for installing a DU bushing, the first mounting hole and the second mounting hole being coaxially arranged, and the inner diameter of the second mounting hole being smaller than the inner diameter of the first mounting hole. This utility model can reduce the pressing stroke of the DU bushing and reduce the processing difficulty of the outer cylinder, making it less likely to cause the outer cylinder to be scrapped.

[0004] The aforementioned "shock absorber outer cylinder" still has some drawbacks. For example, the seals are exposed to harsh environments for a long time. Using them in high temperature and high humidity environments will cause the materials to age, lose elasticity, and affect the sealing performance. Moreover, the working environment of the shock absorber is complex and variable. The intrusion of external pollutants such as dust and foreign objects raised during vehicle operation, as well as mechanical actions such as impact and vibration, will reduce the sealing performance of the outer cylinder. Poor sealing performance will lead to leakage of oil inside the shock absorber, reduce the performance of the shock absorber, and cause environmental pollution.

[0005] To address these issues, a high-sealing shock absorber outer cylinder is proposed. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a high-sealing shock absorber outer cylinder. This solves the problems mentioned in the background art, such as the sealing components being exposed to harsh environments for a long time, and the aging and loss of elasticity caused by use in high-temperature and high-humidity environments, which affects the sealing performance. Furthermore, the working environment of shock absorbers is complex and variable. The intrusion of external pollutants such as dust and foreign objects raised during vehicle operation, as well as mechanical actions such as impact and vibration, all reduce the sealing performance of the outer cylinder. Poor sealing performance can lead to leakage of internal oil in the shock absorber, reduce the performance of the shock absorber, and cause environmental pollution.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-sealing shock absorber outer cylinder, including a bottom shock absorber telescopic tube, a vertical top sleeve movably sleeved on the top of the bottom shock absorber telescopic tube, a side metal heat sink fixedly connected to the surface of the vertical top sleeve, a bottom support vertical frame fixedly connected to one side of the bottom shock absorber telescopic tube, a top transmission ring frame fixedly connected to one side of the bottom support vertical frame, and an inner cleaning brush fixedly connected to the inner side of the top transmission ring frame.

[0008] Preferably, there are two bottom support frames, and the tops of both bottom support frames are fixedly connected to the bottom of the inner cleaning brush, and the tops of the bottom support frames are perpendicular to the bottom of the inner cleaning brush.

[0009] Preferably, the number of side metal heat sinks is multiple, and the multiple side metal heat sinks are arranged in parallel along the surface of the vertical top sleeve.

[0010] Preferably, a side connecting ring is fixedly connected to one side of the vertical top sleeve, a top sliding rail is provided at the top of the side connecting ring, and a bottom support ring frame is slidably connected to the inner side of the top sliding rail.

[0011] Preferably, a transmission fan blade is fixedly connected to the top of the bottom support ring frame, and there are multiple transmission fan blades, all of which are arranged vertically along one side of the bottom support ring frame.

[0012] Preferably, a side L-shaped support frame is fixedly connected to the bottom of the bottom support ring frame, and a side cleaning brush is fixedly connected to one side of the side L-shaped support frame.

[0013] Compared with the prior art, this utility model provides a high-sealing shock absorber outer cylinder, which has the following beneficial effects:

[0014] 1) During the operation of the outer cylinder of the high-sealing shock absorber, when the side metal heat sink accumulates dust due to long-term use, the bottom shock absorber telescopic tube will move vertically during the vertical movement of the bottom shock absorber telescopic tube. The vertical movement of the bottom support vertical tube will drive the top transmission ring frame to move along the surface of the vertical top sleeve. The inner cleaning brush on the inner side of the top transmission ring frame moves along the surface of the vertical top sleeve and cleans the dust particles accumulated on the surface of the side metal heat sink. This improves the performance of the side metal heat sink, enhances the practicality of cooling the side metal heat sink, improves the stability of the vertical top sleeve, and improves the sealing effect.

[0015] 2) During the operation of the outer cylinder of the high-sealing shock absorber, the continuously rotating side L-shaped support frame will drive the side cleaning brush to rotate along the bottom of the vertical top sleeve. The surface of the side cleaning brush is always in contact with the surface of the bottom shock absorber telescopic tube. As the bottom shock absorber telescopic tube moves vertically along the inner side of the vertical top sleeve, the rotating side cleaning brush cleans the surface of the bottom shock absorber telescopic tube when it enters the inner side of the vertical top sleeve. This improves the cleanliness and smoothness of the bottom shock absorber telescopic tube, reduces the friction between the bottom shock absorber telescopic tube and the vertical top sleeve, improves the sealing performance between the bottom shock absorber telescopic tube and the vertical top sleeve during movement, and reduces the situation where friction leads to a decrease in sealing performance.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1 to 4This utility model provides a technical solution: a high-sealing shock absorber outer cylinder, including a bottom shock absorber telescopic tube 1, a vertical top sleeve 2 movably sleeved on the top of the bottom shock absorber telescopic tube 1, a side metal heat sink 301 fixedly connected to the surface of the vertical top sleeve 2, a bottom support vertical frame 302 fixedly connected to one side of the bottom shock absorber telescopic tube 1, a top transmission ring frame 303 fixedly connected to one side of the bottom support vertical frame 302, and an inner cleaning brush 304 fixedly connected to the inner side of the top transmission ring frame 303.

[0024] It should be noted that by using the inner cleaning brush 304 on the inner side of the top drive ring 303 to move along the surface of the vertical top sleeve 2, the inner cleaning brush 304 can clean the dust particles accumulated on the surface of the side metal heat sink 301, thereby improving the performance of the side metal heat sink 301.

[0025] In an optional embodiment, there are two bottom support frames 302, and the tops of the two bottom support frames 302 are fixedly connected to the bottom of the inner cleaning brush 304, and the tops of the bottom support frames 302 are perpendicular to the bottom of the inner cleaning brush 304.

[0026] It should be noted that when the bottom shock absorber telescopic tube 1 rises, it will simultaneously drive the bottom support vertical frame 302 to move vertically. The vertical movement of the bottom support vertical frame 302 will drive the top transmission ring frame 303 to move along the surface of the vertical top sleeve 2. The inner cleaning brush 304 on the inner side of the top transmission ring frame 303 moves along the surface of the vertical top sleeve 2, and the inner cleaning brush 304 cleans the dust particles accumulated on the surface of the side metal heat sink 301.

[0027] In an optional embodiment, there are multiple side metal heat sinks 301, and the multiple side metal heat sinks 301 are arranged in parallel along the surface of the vertical top sleeve 2.

[0028] It should be noted that, by fixing the side metal heat sinks 301 to the surface of the vertical top sleeve 2, when the vertical top sleeve 2 is heated due to the influence of ambient temperature during long-term use, or when the hydraulic oil in the bottom shock absorber telescopic tube 1 is heated due to long-term operation, the temperature of the surface of the vertical top sleeve 2 will be conducted to the surface of the side metal heat sinks 301 by fixing multiple side metal heat sinks 301. The heat dissipation area of ​​the vertical top sleeve 2 is increased by using multiple side metal heat sinks 301, and the temperature of the surface of the vertical top sleeve 2 is quickly dissipated by using more side metal heat sinks 301.

[0029] In an optional embodiment: a side connecting ring 401 is fixedly connected to one side of the vertical top sleeve 2, a top sliding rail 402 is provided on the top of the side connecting ring 401, and a bottom support ring frame 403 is slidably connected to the inner side of the top sliding rail 402.

[0030] It should be noted that as the bottom support ring 403 slides along the surface of the top sliding rail 402, the bottom support ring 403 will rotate stably along the top of the side connecting ring 401. The stably rotating bottom support ring 403 will synchronously drive the two side L support frames 405 to move. The continuously rotating side L support frames 405 will drive the side cleaning brush 406 to rotate along the bottom of the vertical top sleeve 2.

[0031] In an optional embodiment: a transmission fan blade 404 is fixedly connected to the top of the bottom support ring frame 403. There are multiple transmission fan blades 404, and all of the multiple transmission fan blades 404 are arranged vertically along one side of the bottom support ring frame 403.

[0032] It should be noted that airflow is generated during vehicle operation. The airflow blows onto the surface of the vertical top sleeve 2 and comes into contact with multiple drive fan blades 404 on one side of the vertical top sleeve 2. The continuous blowing of the airflow will drive the drive fan blades 404 to move. The multiple drive fan blades 404 will drive the bottom support ring frame 403 to rotate as the wind blows.

[0033] In an optional embodiment: a side L-support frame 405 is fixedly connected to the bottom of the bottom support ring frame 403, and a side cleaning brush 406 is fixedly connected to one side of the side L-support frame 405.

[0034] It should be noted that as the bottom support ring 403 slides along the surface of the top sliding rail 402, the bottom support ring 403 will rotate stably along the top of the side connecting ring 401. The stably rotating bottom support ring 403 will synchronously drive the two side L support frames 405 to move. The continuously rotating side L support frames 405 will drive the side cleaning brush 406 to rotate along the bottom of the vertical top sleeve 2.

[0035] The specific usage and function of this embodiment: During the daily operation of the outer cylinder of the high-sealing shock absorber, it is first fixed to the surface of the vertical top sleeve 2 by the side metal heat sink 301. When the vertical top sleeve 2 is heated by the ambient temperature after long-term use, or when the hydraulic oil in the bottom shock absorber telescopic tube 1 is heated due to long-term operation, the temperature is transferred to the surface of the side metal heat sink 301 by the multiple side metal heat sinks 301 fixed to the surface of the vertical top sleeve 2. The heat of the surface of the vertical top sleeve 2 is transferred to the surface of the side metal heat sink 301, and the heat dissipation area of ​​the vertical top sleeve 2 is increased by the multiple side metal heat sinks 301. The heat of the surface of the vertical top sleeve 2 is quickly dissipated by the numerous side metal heat sinks 301. 01 When dust accumulates due to prolonged use, during the vertical movement of the bottom shock absorber telescopic tube 1, the bottom support vertical frame 302 will move vertically in sync as the bottom shock absorber telescopic tube 1 rises. The vertical movement of the bottom support vertical frame 302 will drive the top transmission ring frame 303 to move along the surface of the vertical top sleeve 2. The inner cleaning brush 304 on the inner side of the top transmission ring frame 303 will move along the surface of the vertical top sleeve 2. The inner cleaning brush 304 will clean the dust particles accumulated on the surface of the side metal heat sink 301, thereby improving the performance of the side metal heat sink 301, improving the practicality of cooling the side metal heat sink 301, improving the stability of the vertical top sleeve 2, and improving the sealing effect.

[0036] Simultaneously, when the vertical top sleeve 2 is exposed to the environment and moves with the vehicle, airflow is generated during vehicle movement. This airflow blows onto the surface of the vertical top sleeve 2 and comes into contact with multiple drive fan blades 404 on one side of the vertical top sleeve 2. The continuous blowing of the airflow drives the drive fan blades 404 to move. The multiple drive fan blades 404, driven by the wind, cause the bottom support ring frame 403 to rotate. Through the sliding of the bottom support ring frame 403 along the surface of the top sliding rail 402, the bottom support ring frame 403 will rotate stably along the top of the side connecting ring 401. The stably rotating bottom support ring frame 403 will synchronously drive the two side L support frames 405 to move. The continuously rotating side L The support frame 405 drives the side cleaning brush 406 to rotate along the bottom of the vertical top sleeve 2, and the surface of the side cleaning brush 406 is always in contact with the surface of the bottom shock absorber telescopic tube 1. During the process of the bottom shock absorber telescopic tube 1 moving vertically along the inner side of the vertical top sleeve 2, the rotating side cleaning brush 406 cleans the surface of the bottom shock absorber telescopic tube 1 when it enters the inner side of the vertical top sleeve 2, which improves the cleanliness and smoothness of the bottom shock absorber telescopic tube 1, reduces the friction between the bottom shock absorber telescopic tube 1 and the vertical top sleeve 2, improves the sealing performance between the bottom shock absorber telescopic tube 1 and the vertical top sleeve 2 during movement, and reduces the situation of reduced sealing performance caused by friction.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
