Description

Technical Field

[0001] This utility model relates to the field of automotive shock absorber technology, specifically a sealed dustproof automotive shock absorber. Background Technology

[0002] Shock absorbers are one of the core components of a car's suspension system. They are mainly used to suppress vibrations caused by uneven or bumpy road surfaces during driving, improving driving comfort, handling stability, and tire grip. Most car shock absorbers are directly exposed, and the springs and sliders easily accumulate dust, mud, or impurities, leading to increased friction during operation and affecting their performance. Therefore, dust covers are used to protect the shock absorbers.

[0003] However, the existing dustproof frame's air intake holes cannot adjust the airflow. The airflow through the dustproof frame's air intake holes is fixed and cannot be adjusted according to the actual operating temperature of the shock absorber. When the shock absorber operates under high intensity for extended periods, such as when the vehicle is driving on continuously bumpy roads or braking frequently, the damping oil generates a large amount of heat. The fixed airflow cannot dissipate this heat in time, causing the shock absorber temperature to rise continuously, the damping oil viscosity to decrease, and the shock absorber's performance to deteriorate. In severe cases, it may even fail, affecting the vehicle's driving safety and comfort. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a closed dustproof automotive shock absorber, which has the advantage of easy adjustment of air intake volume. It solves the problem that the air intake volume cannot be adjusted by the guide holes opened in the existing dustproof frame, and the air intake volume of the guide holes in the dustproof frame is fixed, making it impossible to adjust the ventilation volume according to the actual working temperature of the shock absorber.

[0008] The shock absorber has an upper dustproof frame fixedly connected to the piston rod.

[0009] The lower dustproof frame is slidably connected to the bottom of the upper dustproof frame;

[0010] Adjustment components are provided on the upper dustproof frame and the lower dustproof frame, the adjustment components including:

[0011] The sliding grooves are symmetrically formed on the inner side wall of the lower dustproof frame;

[0019] Preferably, the drive mechanism includes:

[0020] The gear is fixedly connected to the end of the rotating shaft away from the blade;

[0021] Electric push rods are symmetrically arranged inside the lower dustproof frame, and the temperature sensor is electrically connected to the drive mechanism and adjustment component through the vehicle control system;

[0026] Preferably, the frame has multiple symmetrically arranged locations.

[0027] (III) Beneficial Effects

[0028] Compared with the prior art, this utility model provides a closed dustproof automotive shock absorber, which has the following beneficial effects:

[0029] This automotive shock absorber features easy airflow adjustment. A temperature sensor monitors the internal temperature of the lower dust cover. When the temperature reaches a threshold, the sensor transmits the data signal to the vehicle's control system. The control system then controls the electric push rod to retract, which moves the rack upwards. The gear, via a rotating shaft, rotates the blades laterally, creating a wide channel between the blades for smooth airflow and maximizing airflow for rapid heat dissipation. Simultaneously, the incoming air is filtered by a screen to prevent dust from entering the lower dust cover. When the vehicle is parked, the control system extends the output shaft of the electric push rod, moves the rack downwards, and the rotating shaft gradually rotates the blades vertically, reducing the entry of dust and moisture. This design solves the problem of existing dust cover openings that cannot adjust the airflow, resulting in a fixed airflow that cannot be adjusted according to the actual operating temperature of the shock absorber.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Example 1

[0040] See Figure 1-4 A sealed dustproof automotive shock absorber includes a main component 1, which comprises: a shock absorber 11, with an upper dustproof frame 12 fixedly connected to the outside of its piston rod; and a lower dustproof frame 13 slidably connected to the bottom of the upper dustproof frame 12. Adjustment components 2 are provided on the upper dustproof frame 12 and the lower dustproof frame 13. The adjustment components 2 include: a sliding groove 21 symmetrically formed on the inner wall of the lower dustproof frame 13; and a slider 22 symmetrically and fixedly connected to the outer wall of the upper dustproof frame 12. 2. Sliding connection within the slide groove 21; 23. symmetrically opened on the outer side wall of the lower dustproof frame 13; 24. symmetrically and rotatably connected to the inner side wall of the slide groove 23; 25. symmetrically and fixedly connected to the outer side wall of the 24; 251. Temperature sensor 251. Set on the inner side wall of the lower dustproof frame 13; 26. symmetrically and fixedly connected within the slide groove 23; 27. Drive mechanism 27. Set on the lower dustproof frame 13, the 24, and the temperature sensor 251. The drive mechanism 27 includes: a gear 271, fixedly connected to the end of the rotating shaft 24 away from the blade 25; an electric push rod 272, symmetrically arranged inside the lower dustproof frame 13, the temperature sensor 251 being electrically connected to the drive mechanism 27 and the adjustment component 2 via the vehicle control system; and a rack 273, fixedly connected to the bottom output shaft of the electric push rod 272, the rack 273 being movable within the cavity of the lower dustproof frame 13, and meshing with both the rack 273 and the gear 271. Buffer blocks 5 are symmetrically arranged on the inner wall of the slider 22, the buffer blocks 5 being located on the upper and lower sides of the slider 22.

[0041] During use, the upper dustproof frame 12 extends and retracts with the piston rod of the shock absorber 11. The upper dustproof frame 12 drives the slider 22 to slide within the slide groove 21. The upper dustproof frame 12 and the lower dustproof frame 13 protect the shock absorber 11, preventing dust or mud from contacting the shock absorber 11. When the shock absorber 11 is running, the temperature sensor 251 monitors the internal temperature of the lower dustproof frame 13. When the temperature reaches the threshold, the temperature sensor 251 transmits the data signal to the vehicle control system. The control system controls the electric push rod 272 to retract. The electric push rod 272 drives the rack 273 to move upward. When the rack 273 moves, it drives the gear 271 to rotate. The gear 271 drives the blades 25 to rotate through the rotating shaft 24, rotating the blades 25 to the side. At this time, a wide channel is formed between the blades 25, allowing airflow to pass smoothly and maximizing the air intake for rapid heat dissipation. At the same time, the incoming air is filtered by the filter screen 26, preventing dust from entering the interior of the lower dustproof frame 13. When the car stops, the control system extends the output shaft of the electric push rod 272, moves the rack 273 downward, and drives the rotating shaft 24 to gradually rotate the blade 25 to a vertical position, reducing the entry of dust and moisture. The buffer block 5 is made of an elastic material, such as polyurethane. When the shock absorber 11 is compressed or stretched to its limit position, the buffer block 5 can buffer the impact of the slider 22 and avoid hard metal collisions.

[0042] Example 2

[0043] An auxiliary function has been added based on Embodiment 1.

[0044] See Figure 1-4 A scraper 3 is fixedly connected to the top of the lower dustproof frame 13, and the upper dustproof frame 12 is slidably connected to the inside of the scraper 3. A frame body 4 is fixedly connected to the inner side wall of the lower dustproof frame 13, and activated carbon is placed inside the frame body 4. Multiple frames 4 are symmetrically arranged.

[0045] As the upper dustproof frame 12 moves downwards with the use of the shock absorber 11, the scraper 3 slides on the outer wall of the upper dustproof frame 12, scraping away dust or impurities adhering to the surface of the upper dustproof frame 12. The impurities fall downwards through the slope of the scraper 3, preventing impurities adhering to the outside of the upper dustproof frame 12 from being carried into the lower dustproof frame 13. When the guide channel 23 dissipates heat, the activated carbon inside the frame 4 absorbs moisture from the air, reducing the humidity inside the lower dustproof frame 13 and preventing it from affecting the normal use of the shock absorber 11. As the temperature inside the lower dustproof frame 13 rises, the activated carbon is gradually dried, facilitating its recycling. The multiple frames 4 increase the activated carbon content inside the lower dustproof frame 13, and the dispersed arrangement allows the activated carbon at each point to evenly distribute the adsorption load, preventing premature saturation in some areas.
