Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, specifically to a main bracket for an automotive shock absorber. Background Technology
[0002] Most car shock absorber main brackets do not have a protective structure for the shock absorber, leaving the entire shock absorber exposed. This makes it easy for foreign objects to get stuck inside the shock absorber spring, affecting the overall performance of the shock absorber.
[0003] The Chinese patent CN222522419U discloses a main bracket for an automotive shock absorber. This main bracket for an automotive shock absorber uses a protective component that is movably installed between an upper mounting base and a lower mounting base. The protective component can be easily installed using fixing bolts and a limiting structure. Therefore, this device can protect the shock absorber body and the shock absorber spring through the linkage of the upper housing, the lower housing, and the rubber sleeve, thereby preventing foreign objects from getting stuck inside the shock absorber spring and affecting the overall performance of the shock absorber.
[0004] However, automotive shock absorbers convert the kinetic energy of vehicle vibration into heat energy through the flow resistance of hydraulic oil during the compression and extension strokes. Therefore, compared to exposed automotive shock absorbers, those enclosed by protective components are less effective at heat dissipation and cannot quickly dissipate the heat generated during operation, which can easily lead to reduced efficiency of the shock absorbers when the temperature is high. Utility Model Content
[0005] The purpose of this utility model is to provide a main bracket for an automotive shock absorber to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a main bracket for an automotive shock absorber, comprising an upper mounting base and a lower mounting base, wherein a connecting base is fixedly mounted on the top of the upper mounting base, and a shock absorber body is fixedly mounted on the bottom of the connecting base; the telescopic end of the shock absorber body is fixedly connected to the top of the lower mounting base; the upper mounting base and the lower mounting base are elastically connected by a shock-absorbing spring; the shock-absorbing spring is sleeved outside the shock absorber body, and a protective component is provided outside the shock-absorbing spring;
[0007] The protective assembly includes an upper protective cylinder and a lower protective cylinder. The bottom end of the lower protective cylinder is fixedly installed on the top of the lower mounting base, and the top end of the upper protective cylinder is fixedly installed on the bottom of the upper mounting base. The lower protective cylinder is slidably sleeved on the outside of the upper protective cylinder. The outer wall of the upper protective cylinder has ventilation holes. A ceramic sealing ring and a ceramic scraping ring are fixedly sleeved on the outer wall of the upper protective cylinder. The ceramic sealing ring and the ceramic scraping ring are located in the gap between the upper and lower protective cylinders.
[0008] Furthermore, a dustproof net is fixedly installed on the inner wall of the upper protective cylinder, which covers the ventilation holes on the upper protective cylinder.
[0009] Furthermore, two ceramic sealing rings and two ceramic scraper rings are provided, and the top and top edge of the ceramic sealing ring are provided with slopes.
[0010] Furthermore, a rain shield is fixedly fitted onto the outer wall of the upper protective cylinder, and the rain shield is located near the top of the upper protective cylinder.
[0011] Furthermore, a drainage hole is provided at the bottom of the lower mounting base, and the drainage hole is located inside the lower protective cylinder.
[0012] Furthermore, a second dustproof net is fixedly installed on the top of the lower mounting base, which blocks the drainage hole.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] The upper and lower protective cylinders form a protective sleeve for the shock absorber body and the shock absorber spring. Ventilation holes are opened on the upper protective cylinder to ensure air circulation inside and outside the protective sleeve composed of the upper and lower protective cylinders. The flowing air dissipates the heat generated by the shock absorber body and the shock absorber spring during operation. When the shock absorber body and the shock absorber spring are working, the internal space of the protective sleeve composed of the upper and lower protective cylinders will expand and contract, thereby compressing or drawing in air, allowing air to be better discharged and entered, further accelerating the air flow rate, and thus improving the heat dissipation efficiency.
[0015] Furthermore, because the upper and lower protective cylinders are slidably connected, the lower protective cylinder slides relative to the upper protective cylinder when the shock absorber body and shock absorber spring are working, ensuring that it does not obstruct the operation of the shock absorber body and shock absorber spring. A ceramic sealing ring is installed in the gap between the upper and lower protective cylinders to achieve sliding sealing and to ensure that the upper protective cylinder does not radially offset relative to the lower protective cylinder. A ceramic scraper ring is installed to scrape away debris that enters the gap between the upper and lower protective cylinders, preventing debris from getting stuck in the gap and thus causing the upper and lower protective cylinders to be obstructed from sliding.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Please see Figures 1-5 This utility model provides a technical solution: a main bracket for an automotive shock absorber, including an upper mounting base 2 and a lower mounting base 3. A connecting base 1 is fixedly installed on the top of the upper mounting base 2, and a shock absorber body 4 is fixedly installed on the bottom of the connecting base 1. The telescopic end of the shock absorber body 4 is fixedly connected to the top of the lower mounting base 3. The upper mounting base 2 and the lower mounting base 3 are elastically connected by a shock-absorbing spring 5. The shock-absorbing spring 5 is sleeved on the outside of the shock absorber body 4, and a protective component 6 is provided on the outside of the shock-absorbing spring 5.
[0024] The protective component 6 includes an upper protective cylinder 601 and a lower protective cylinder 602. The bottom end of the lower protective cylinder 602 is fixedly installed on the top of the lower mounting base 3, and the top end of the upper protective cylinder 601 is fixedly installed on the bottom of the upper mounting base 2. The lower protective cylinder 602 is slidably sleeved on the outside of the upper protective cylinder 601. A ventilation hole 603 is provided on the outer wall of the upper protective cylinder 601. A ceramic sealing ring 604 and a ceramic scraper ring 605 are fixedly sleeved on the outer wall of the upper protective cylinder 601. 605 is located within the gap between the upper protective cylinder 601 and the lower protective cylinder 602. The upper and lower protective cylinders 601 and 602 form a protective sleeve for the shock absorber body 4 and the shock absorber spring 5. Because the upper and lower protective cylinders 601 and 602 are slidably connected, the lower protective cylinder 602 slides relative to the upper protective cylinder 601 when the shock absorber body 4 and the shock absorber spring 5 are working, ensuring that it does not obstruct the operation of the shock absorber body 4 and the shock absorber spring 5. A ceramic sealing ring 604 is provided in the gap between the upper protective cylinder 601 and the lower protective cylinder 602 to achieve sliding sealing and to ensure that the upper protective cylinder 601 does not radially offset relative to the lower protective cylinder 602. A ceramic scraper ring 605 is provided to scrape away debris that enters the gap between the upper protective cylinder 601 and the lower protective cylinder 602 to prevent debris from getting stuck in the gap and thus causing the upper protective cylinder 601 and the lower protective cylinder 602 to be obstructed from sliding. A ventilation hole 603 is provided on the upper protective cylinder 601 to ensure air circulation inside and outside the protective sleeve composed of the upper protective cylinder 601 and the lower protective cylinder 602. The flowing air is used to dissipate the heat generated by the shock absorber body 4 and the shock absorber spring 5 when they are working. When the shock absorber body 4 and the shock absorber spring 5 are working, the internal space of the protective sleeve composed of the upper protective cylinder 601 and the lower protective cylinder 602 will increase and decrease, thereby squeezing or drawing in air, so that the air can be better discharged and entered, which can further accelerate the air flow rate and improve the heat dissipation efficiency.
[0025] A dustproof net 7 is fixedly installed on the inner wall of the upper protective cylinder 601. The dustproof net 7 covers the ventilation hole 603 on the upper protective cylinder 601. The dustproof net 7 is set to prevent dust, hair and fibers in the air from entering the upper protective cylinder 601 and the lower protective cylinder 602, and then adsorbing onto the shock absorber body 4 and the shock absorber spring 5.
[0026] Two ceramic sealing rings 604 and two ceramic scraper rings 605 are provided. The top and top edge of the ceramic sealing ring 604 are provided with slopes. The slopes make the initial gap size smaller when the ceramic sealing ring 604 moves axially, so that it is not easy to get stuck.
[0027] A rain shield 10 is fixedly fitted on the outer wall of the upper protective cylinder 601. The rain shield 10 is close to the top of the upper protective cylinder 601. The rain shield 10 reduces the amount of rainwater entering through the ventilation hole 603.
[0028] The bottom of the lower mounting base 3 is provided with a drainage hole 8, which is located inside the lower protective cylinder 602. The drainage hole 8 is provided to drain rainwater that enters the protective sleeve.
[0029] A dustproof net 2 9 is fixedly installed on the top of the lower mounting base 3. The dustproof net 2 9 blocks the drainage hole 8. The dustproof net 2 9 is set to prevent dust, hair and fibers in the air from entering the upper protective cylinder 601 and the lower protective cylinder 602, and then adsorbing onto the shock absorber body 4 and the shock absorber spring 5.
[0030] Working principle: When in use, when the shock absorber body 4 and the shock absorber spring 5 are working, the lower protective cylinder 602 slides relative to the upper protective cylinder 601, causing the internal space of the protective sleeve composed of the upper protective cylinder 601 and the lower protective cylinder 602 to increase and decrease at different times, thereby squeezing or drawing in air, thus accelerating the air and using the fast-flowing airflow to carry away the heat generated by the shock absorber body 4 and the shock absorber spring 5 during operation.
[0031] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
