Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, specifically to an automotive shock absorber. Background Technology

[0002] In the automotive industry, suspension systems were developed to address different road conditions, improve comfort, and enhance ride smoothness. Shock absorbers are installed in parallel with elastic elements in the suspension to dampen vibrations. Hydraulic shock absorbers are commonly used in automotive suspension systems. Shock absorbers are crucial components of the vehicle's suspension system, acting to buffer road impacts and dampen suspension and body vibrations. Their performance directly affects vehicle handling and comfort. Shock absorbers are not only used in the suspension but also in other areas of the car, such as the driver's cab, seats, and steering wheel.

[0003] Most shock absorbers on the market are affected by outdoor dust, sand and other debris during vehicle use, which easily cause impurities to adhere to their surface. Over time, the shock absorbers are prone to wear, resulting in reduced impact force or even oil leakage, affecting their subsequent service life. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an automotive shock absorber that effectively solves the problem that existing shock absorbers are easily affected by outdoor environments during use, leading to impurities adhering to their surface and wear and tear over long periods of use, thus affecting their service life.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: an automotive shock absorber, comprising a shock absorber body, and an upper dust cover and a lower dust cover mounted on the shock absorber body for dust protection, wherein the upper dust cover and the lower dust cover are movably connected, a buffer assembly for further cushioning is installed on the top of the upper dust cover, and a synchronization assembly is installed on one side wall of the buffer assembly. The upper dust cover and the lower dust cover are movably connected, which can effectively cover the shock absorber body, thereby preventing dust from adhering to the shock absorber body due to the external environment. The system includes two cleaning components for cleaning dust from the surface of the lower dust cover. Each component comprises two hinged clamping plates mounted on the side wall of the synchronizing assembly near the shock absorber body. Cleaning pads are detachably connected to the inner arc surfaces of both clamping plates, and integrally formed connecting plates are provided on the outer arc surfaces of both clamping plates. Each connecting plate has a pre-drilled through hole through which a fastening bolt is inserted. A hand-tightening nut for locking the two clamping plates is threaded onto the fastening bolt. During outdoor vehicle operation, the shock absorber body cleans the lower dust cover using the cleaning pads during the cushioning process, improving its overall service life. The hinged installation of the clamping plates facilitates subsequent maintenance and repair. The detachable connection of the cleaning pads allows for easy cleaning and replacement. The overall structure is simple and easy to operate.

[0006] Preferably, the buffer assembly includes a fixed shell with a circular slot pre-set in the middle of the fixed shell, and the circular slot communicates with the interior of the fixed shell. A guide rod is fixed inside the fixed shell, and the middle of the guide rod is divided equally by a partition plate. The guide rod on both sides of the partition plate is movably equipped with a slide seat, and a compression spring is provided between the opposite sides of the two slide seats and the fixed shell, which is sleeved on the guide rod. An adjusting rod is hinged to each of the two slide seats for use with the dust cover. When the shock absorber body is working, the buffer assembly located at the top of the dust cover will gradually move within the fixed shell through the guide plate, and the adjusting rod will gradually control the two slide seats to move in opposite directions or towards each other, thereby compressing the compression spring and achieving the purpose of further buffering, thereby increasing the comfort of the passengers.

[0007] Preferably, a guide plate is fixed to the top of the upper dust cover. The guide plate is cylindrical and is movably disposed in a circular slot. The top of the guide plate is mounted on the end of the adjusting rod away from the slide block via a hinge seat.

[0008] Preferably, the synchronization component includes a slide rod mounted on one side wall of the fixed housing via a bracket, a first rack disposed on a selectable slide block, and a rotating shaft rotatably disposed within the fixed housing. Two gears are disposed on the rotating shaft, wherein one of the selectable gears meshes with the first rack for transmission. A sliding block is slidably disposed on the slide rod, wherein one end of the sliding block is fixed with a mounting bracket for connecting the cleaning component, and a second rack that meshes with the other gear is disposed on the top of the mounting bracket.

[0009] Preferably, the shock absorber body includes a cylinder and an oil reservoir movably disposed inside the cylinder. A piston rod is provided inside the cylinder, passing through the oil reservoir and capable of piston movement. A bottom valve is provided at the bottom of the oil reservoir. Cylinder covers are provided at opposite ends of the cylinder and the oil reservoir, and a buffer spring is provided between the two cylinder covers for fitting onto the cylinder and the oil reservoir.

[0010] Preferably, the inner arc surfaces of the two clamping plates are provided with grooves in the shape of a "T", into which the cleaning pad can be snapped. The cleaning pad is made of rubber and ensures that the surface of the lower dust cover can be cleaned. The removable cleaning pad also facilitates subsequent cleaning or replacement by the staff.

[0011] Preferably, the surface of the upper dust cover has a plurality of guide strips distributed in a ring, and the interior of the corresponding lower dust cover has a guide groove distributed in a ring for the movement of the guide strips. The cooperation between the guide strips and the guide grooves can ensure the stability of their up-and-down movement.

[0012] Preferably, the opposite ends of the fixed shell and the lower dust cover are both fixed with supports.

[0013] Preferably, both sides of the slide are provided with protrusions, and the inner wall of the corresponding fixed shell is provided with a sliding groove for the movement of the protrusions. The cooperation between the protrusions and the sliding groove can ensure the stability of the slide when it moves.

[0014] Preferably, the distance between the two cleaning components is one-third of the length of the lower dust cover. The distance between the two cleaning components is such that the two cleaning components can perform the cleaning operation on the lower dust cover during the movement of the shock absorber body.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides an automotive shock absorber with the following advantages: 1. This invention, through the setting of an upper dust cover, a lower dust cover, and a cleaning component, with the upper and lower dust covers connected by a movable connection, can effectively cover the shock absorber body, thereby preventing dust from adhering to the shock absorber body due to the external environment. Furthermore, during outdoor vehicle driving, the shock absorber body, in the cushioning process, will use the cleaning pad to clean the lower dust cover, thus improving its overall service life. The hinged installation between the clamps facilitates subsequent maintenance and repair by personnel. Simultaneously, the detachable connection of the cleaning pad allows for easy cleaning and replacement by personnel. The overall structure is simple and easy to operate.

[0016] 2. The present invention uses a buffer component. When the shock absorber body is working, the buffer component located at the top of the upper dust cover will gradually move within the fixed shell through the guide plate. For this purpose, the two sliding blocks are gradually controlled to move in opposite directions or towards each other through the adjusting rod, thereby compressing the compression spring and achieving the purpose of buffering again, thereby increasing the comfort of passengers.

[0017] 3. The present invention, through the setting of the synchronization component, when the slide in the buffer component moves back and forth by compression and rebound, will cause the rotating shaft to start rotating through the mutual meshing between the first rack and the gear. For this purpose, the mutual meshing between the gear and the second rack will gradually drive the mounting frame to reciprocate and lift. Thus, the mounting frame drives the cleaning component to reciprocate, thereby improving the cleaning ability of the lower dust cover. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] The present invention will be further described below with reference to embodiments.

[0023] Example: A car shock absorber, such as Figures 1-8 As shown, the device includes a shock absorber body 1, and an upper dust cover 2 and a lower dust cover 3 covering the shock absorber body 1 for dust protection. The shock absorber body 1 includes a cylinder 101 and an oil reservoir 103 movably disposed within the cylinder 101. A piston rod 104 is disposed within the cylinder 101, passing through the oil reservoir 103 and capable of piston movement within it. The space between the piston position of the piston rod 104 and the oil reservoir 103 is used to store medium oil, thereby effectively buffering it during operation. The oil reservoir 103... The bottom of the cylinder is provided with a bottom valve 106. Cylinder covers 102 are provided at opposite ends of the cylinder barrel 101 and the oil reservoir 103. A buffer spring 105 is provided between the two cylinder covers 102 for sleeved on the cylinder barrel 101 and the oil reservoir 103. Under the action of the buffer spring 105 and the oil reservoir 103, the vibration reduction and buffering purpose can be effectively achieved. The upper dust cover 2 and the lower dust cover 3 are movably connected. A buffer assembly 5 for further buffering is installed on the top of the upper dust cover 2. A synchronization assembly 6 is installed on one side wall of the buffer assembly 5. The upper dust cover 2 has several guide strips 9 distributed in a ring on its surface, and the corresponding lower dust cover 3 has guide grooves distributed in a ring inside for the movement of the guide strips 9. During the production process, the guide strips 9 can be easily connected to the guide grooves, which facilitates installation and also allows the vibration damper body 1 to move. At the same time, the upper dust cover 2 and the lower dust cover 3 are connected by a movable connection, which can effectively cover the vibration damper body 1, thereby preventing dust from adhering to the vibration damper body 1 due to the external environment. Combination Figure 6 As shown, the synchronization component 6 is equipped with two cleaning components 7 for cleaning the surface dust of the lower dust cover 3. These include two hinged clamping plates 701 mounted on the side wall of the synchronization component 6 near the shock absorber body 1. The cleaning components 7 are mounted on the mounting bracket 602. Cleaning pads 703 are detachably connected to the inner arc surfaces of both clamping plates 701. It should be noted that the inner arc surfaces of the two clamping plates 701 have grooves with a "T"-shaped cross-section. The cleaning pads 703 can be snapped into these grooves. The cleaning pads 703 are made of rubber. When the shock absorber body 1 is working, the lower dust cover 3 can move on the cleaning pads 703, effectively cleaning the dust on the lower dust cover 3. The distance between the two cleaning components 7 is one-third the length of the lower dust cover 3. When the shock absorber body 1 is working, the movable range of the lower dust cover 3 allows the two cleaning components 7 to perform full-range cleaning of the entire lower dust cover 3. The two clamping plates 701 are each provided with an integrally formed connecting plate 702 on their outer arc surfaces. Each connecting plate 702 has a through hole 704. A fastening bolt 705 is inserted into the two through holes 704, and a hand-tightening nut 706 for locking the two clamping plates 701 is threaded onto the fastening bolt 705. When the two clamping plates 701 are joined together, the clamping plates 701 can be effectively fixed by passing the fastening bolt 705 through the two through holes 704 and threading the hand-tightening nut 706 onto the fastening bolt 705, thus ensuring the subsequent cleaning operation. Combination Figure 4 , Figure 5 as well as Figure 7As shown, the buffer assembly 5 includes a fixed shell 501. A circular slot is pre-set in the middle of the fixed shell 501. The fixed shell 501 is formed by combining a rectangle and a cylinder. The circular slot is located in the position area of ​​the cylinder and communicates with the interior of the fixed shell 501. A guide rod 502 is fixed inside the fixed shell 501. The middle of the guide rod 502 is divided equally by a partition plate. The guide rod 502 on both sides of the partition plate is movably equipped with a slide block 503. In order to ensure the stability of the movement of the slide block 503, the slide block 503... Both sides of the slide 503 are provided with protrusions. The inner wall of the corresponding fixed shell 501 is provided with a sliding groove for the movement of the protrusions. The protrusions can move in the sliding groove to ensure the stability of the movement of the slide 503. A compression spring 504 is provided between the opposite sides of the two slides 503 and the fixed shell 501, which is sleeved on the guide rod 502. An adjusting rod 505 is hinged to the two slides 503 to cooperate with the dust cover 2. The adjusting rod 505 can cause the two slides 503 to move towards or away from each other during the movement, and the force is decomposed by squeezing the compression spring 504. The top of the upper dust cover 2 is fixed with a guide plate 8, which is cylindrical and movably set in a circular slot. The top of the guide plate 8 is mounted on the end of the adjusting rod 505 away from the slide 503 via a hinge seat. When the damper body 1 is working, the upper dust cover 2 moves synchronously, causing the guide plate 8 to move in the circular slot. The adjusting rod 505 gradually controls the two slides 503 to move in opposite directions or towards each other, thereby compressing the compression spring 504 to achieve the purpose of buffering again. The fixed shell 501 and the lower dust cover 3 are both fixed with supports 4 at opposite ends. The use of supports 4 facilitates the installation of the whole.

[0024] The synchronization component 6 includes a slide rod 601 mounted on one side wall of the fixed housing 501 via a bracket, a first rack 603 mounted on a selector slide 503, and a rotating shaft 604 rotatably mounted inside the fixed housing 501. Two gears 605 are mounted on the rotating shaft 604, with one gear 605 meshing with the first rack 603. A sliding block is slidably mounted on the slide rod 601, with one end of the sliding block fixed to a mounting bracket 602 for connecting the cleaning component 7. A connection point for the other gear 605 is located on the top of the mounting bracket 602. When the second rack 606 engages with the buffer assembly 5, the slide 503 reciprocates due to compression and rebound by the compression spring 504. This reciprocating motion causes the rotating shaft 604 to start rotating through the meshing between the first rack 603 and the gear 605. To this end, the meshing between the other gear 605 and the second rack 606 gradually drives the mounting frame 602 to reciprocate and lift. This, in turn, drives the cleaning assembly 7 to reciprocate, thereby improving the cleaning ability of the lower dust cover 3.

[0025] Specifically, the corresponding support 4 is installed at the bottom of the vehicle to form a suspension system. The upper dust cover 2 and the lower dust cover 3 are connected by a movable connection, which can effectively cover the shock absorber body 1, thereby preventing dust from adhering to the shock absorber body 1 due to the external environment. When the car is driving outdoors, during the cushioning process, the upper dust cover 2 will move synchronously to cause the guide plate 8 to move in the circular slot. The adjusting rod 505 gradually controls the two sliding seats 503 to move in opposite directions or towards each other, thereby compressing the compression spring 504 to achieve the purpose of cushioning again. During this period, when the lower dust cover 3 moves, it will move on the cleaning pad 703, which can effectively clean the dust on the lower dust cover 3, preventing dust from directly or indirectly affecting the overall service life. The clamps 701 are hinged together, which can facilitate the subsequent maintenance and repair of the staff. At the same time, the cleaning pad 703 is detachably connected, which can facilitate the cleaning and replacement of the staff.
