Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering, and in particular to a two-stage damping automatic adjustment shock absorber. Background Technology

[0002] Shock absorbers are devices used to suppress the oscillations caused by the rebound of springs after absorbing shock and to absorb impacts from the road surface. They are widely used in automobiles, machinery, and other fields. Their working principle is based on damping characteristics; they dissipate vibration energy by controlling the flow of oil or gas, thereby reducing the impact of vibration on equipment or vehicles. Two-stage shock absorbers, through different stages of damping adjustment, provide more suitable shock absorption performance for equipment or vehicles under different operating conditions.

[0003] Currently, most traditional automotive two-stage damping shock absorbers have non-adjustable damping coefficients, making them unsuitable for complex and changing road or operating conditions. Even some adjustable damping shock absorbers require manual adjustment, which is difficult to do promptly and flexibly under heavy loads or sudden changes in road conditions. This results in poor shock absorption performance, affecting the stability and lifespan of the equipment, and reducing the comfort of passengers. Therefore, we propose a two-stage damping automatic adjustment shock absorber to solve these problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a two-stage damping automatic adjustment shock absorber, including a crossbeam plate and a base plate. A T-shaped limiting groove is opened at the bottom of the crossbeam plate. An adjusting block is slidably connected to the inner side wall of the T-shaped limiting groove. Two limiting plates that slide with the inner wall of the T-shaped limiting groove are fixedly installed on the outer side wall of the adjusting block. The adjusting block and the base plate are connected to the crossbeam plate and the base plate through two sets of limiting damping shock absorber components.

[0008] The limiting damping shock absorber assembly consists of a damping hydraulic rod and a shock absorber spring. The shock absorber spring is sleeved on the outer wall of the damping hydraulic rod. A support base is fixedly installed at the bottom of the crossbeam plate. Limit bolts are rotatably connected to the support base, the adjusting block, and the outer wall of the base plate. The inner wall of the end hole of the damping hydraulic rod and the outer wall of the limit bolt are fixedly connected.

[0009] The adjusting block and the base plate are arranged coaxially.

[0010] The two limiting damping shock absorber components located between the adjusting block and the base plate are symmetrically arranged on both sides of the adjusting block, and the two limiting damping shock absorber components located between the crossbeam plate and the base plate are symmetrically arranged on both sides of the base plate.

[0011] A limiting mechanism is provided on the inner wall of the T-shaped limiting groove. The limiting mechanism includes two limiting blocks that are slidably connected to the inner wall of the T-shaped limiting groove. A limiting groove is provided on the outer wall of the limiting block. A limiting bolt is fixedly installed on the side of the limiting plate.

[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] According to one embodiment of the present invention, in conjunction with Figure 1-2 As shown. A two-stage damping automatic adjustment shock absorber includes a crossbeam plate 1 and a base plate 2. A T-shaped limiting groove 3 is provided at the bottom of the crossbeam plate 1. An adjusting block 4 is slidably connected to the inner side wall of the T-shaped limiting groove 3. Two limiting plates 5 are fixedly installed on the outer side wall of the adjusting block 4 and slide against the inner wall of the T-shaped limiting groove 3. The adjusting block 4 and the base plate 2 are connected to the crossbeam plate 1 and the base plate 2 through two sets of limiting damping shock absorber components 6.

[0024] To further explain, the crossbeam plate 1 and the bottom plate 2 are connected by two sets of limiting damping shock absorption components 6. Together with the adjustment block 4 and another set of limiting damping shock absorption components 6 between the crossbeam plate 1, two-stage damping adjustment is formed, which can provide more flexible and precise shock absorption and buffering according to different working conditions and stress conditions, and adapt to complex and ever-changing vibration environments.

[0025] like Figure 1-2 As shown, the limiting damping shock absorber assembly 6 consists of a damping hydraulic rod and a shock absorber spring. The shock absorber spring is sleeved on the outer wall of the damping hydraulic rod. A support base is fixedly installed at the bottom of the crossbeam plate 1. Limit bolts are rotatably connected to the outer walls of the support base, the adjusting block 4, and the base plate 2. The inner wall of the end hole of the damping hydraulic rod and the outer wall of the limit bolt are fixedly connected.

[0026] To further explain, the limiting damping shock absorber assembly 6 consists of a damping hydraulic rod and a shock absorber spring. The damping hydraulic rod provides stable damping force to control the vibration decay rate, while the shock absorber spring provides elastic buffering. The combination of the two can effectively absorb and disperse vibration energy, improving shock absorption performance. Through the connection method of the support base, limiting bolt and damping hydraulic rod, the components are firmly assembled, ensuring that the limiting damping shock absorber assembly 6 will not loosen or fall off under long-term vibration conditions, ensuring the reliability and service life of the shock absorber.

[0027] like Figure 1-2 As shown, the adjusting block 4 and the base plate 2 are coaxially arranged.

[0028] To further explain, this design ensures that the force is evenly distributed during the shock absorption process, avoiding localized wear or structural damage caused by eccentric force, enabling the shock absorber to function more stably during operation and extending the overall service life of the equipment.

[0029] like Figure 1-2 As shown, the two limiting damping shock absorber components 6 located between the adjusting block 4 and the base plate 2 are symmetrically arranged on both sides of the adjusting block 4, and the two limiting damping shock absorber components 6 located between the crossbeam plate 1 and the base plate 2 are symmetrically arranged on both sides of the base plate 2.

[0030] To further explain, this design ensures that the shock absorber has consistent damping performance in all directions. Regardless of the direction of the vibration, it can provide balanced buffering and damping force, effectively preventing the equipment from tilting or shaking due to uneven force, and improving the stability of equipment operation.

[0031] like Figure 1 and Figure 3 As shown, a self-adjusting mechanism is provided on the inner wall of the T-shaped limiting groove 3; the self-adjusting mechanism includes an inverted convex groove 7 opened on the top of the crossbeam plate 1, an inverted convex plate 8 is slidably connected to the inner wall of the inverted convex groove 7, the crossbeam plate 1 and the inverted convex plate 8 are detachably connected by multiple fixing bolts 9, the adjusting block 4 and the inverted convex plate 8 are connected by multiple damping rods 10, and a return spring 11 is slidably sleeved on the outer wall of the damping rod 10.

[0032] To further explain, the inverted convex plate 8, damping rod 10 and return spring 11 in the self-adjusting mechanism work together. When the equipment is subjected to vibration and impact, the adjusting block 4 slides in the T-shaped limiting groove 3, which drives the inverted convex plate 8 to move. The damping rod 10 is compressed, causing the return spring 11 to deform, and automatically adjusting the damping force of the shock absorber to achieve adaptive adjustment of vibration.

[0033] like Figure 1 and Figure 4As shown, a limiting mechanism is provided on the inner wall of the T-shaped limiting groove 3. The limiting mechanism includes two limiting blocks 12 that are slidably connected to the inner wall of the T-shaped limiting groove 3. A limiting groove 13 is provided on the outer wall of the limiting block 12. A limiting bolt 14 is fixedly installed on the side of the limiting plate 5. The outer wall of the limiting bolt 14 on the same side is slidably connected to the inner wall of the limiting groove 13. The outer wall of the limiting block 12 and the inner wall of the T-shaped limiting groove 3 are connected by multiple limiting springs 15.

[0034] To further explain, the limiting block 12, limiting groove 13, and limiting spring 15 of the limiting mechanism work together. When the adjusting block 4 slides, the limiting bolt 14 slides along the limiting groove 13. Under the action of the limiting spring 15, the limiting block 12 can limit the sliding range of the adjusting block 4, preventing the adjusting block 4 from sliding excessively and disengaging from the T-shaped limiting groove 3, thus playing a limiting protection role. The design of the limiting groove 13 can assist the adjusting block 4 in changing its motion state more smoothly during the sliding process. When a certain displacement is reached, the sliding speed and direction of the adjusting block 4 can be adjusted through the cooperation of the limiting groove 13 and the limiting bolt 14, thereby enhancing the responsiveness and stability of the shock absorber's automatic adjustment.

[0035] like Figure 1 and Figure 4 As shown, the two ends of the limiting spring 15 are fixedly connected to the outer wall of the limiting block 12 and the inner wall of the T-shaped limiting groove 3, respectively.

[0036] To further explain, this design ensures that the limiting spring 15 can stably provide restoring force to the limiting block 12 during operation, so that the limiting block 12 always maintains its limiting effect on the adjusting block 4, thus ensuring the reliability of the limiting mechanism.

[0037] like Figure 1 As shown, the inner wall edge of the limiting slope trough 13 located at the top is rounded.

[0038] To further explain, this design reduces friction and wear of the limiting bolt 14 during the sliding process, lowers motion resistance, makes the sliding of the adjusting block 4 smoother, and avoids damage to the limiting bolt 14 caused by sharp edges, thus extending the service life of the components and improving the overall performance of the shock absorber.

[0039] The functional principle of this utility model can be explained through the following operation methods:

[0040] 1. Equipment installation and component connection

[0041] Horizontally fix the crossbeam plate 1 to the bottom of the equipment requiring shock absorption or the supporting structure, such as the connection end of the vehicle suspension system, ensuring that the mounting surface is flat and the bolts are tight. Simultaneously fix the base plate 2 to the corresponding supporting surface below, such as the vehicle frame, so that the crossbeam plate 1 and the base plate 2 are parallel and the spacing meets the design requirements.

[0042] Slide the adjusting block 4 into the T-shaped limiting groove 3 at the bottom of the crossbeam plate 1, so that the limiting plates 5 on both sides of the adjusting block 4 fit tightly against the inner wall of the T-shaped groove, ensuring that the adjusting block 4 can slide horizontally in the groove but will not fall off. Then, put the end holes of the damping hydraulic rod of the limiting damping shock absorber assembly 6 into the limiting bolts on the support base, the adjusting block 4 and the outer wall of the base plate 2 respectively. By rotating the limiting bolts, fix them to the end holes of the damping hydraulic rod to form a rotatable hinge structure. At the same time, fix one end of the damping rod 10 to the outer wall of the adjusting block 4, and pass the other end through the connecting hole of the inverted convex plate 8. After putting on the return spring 11, fix it to the inverted convex plate 8, so that the inverted convex plate 8 can slide in the inverted convex groove 7 at the top of the crossbeam plate 1 and be subjected to the elastic force of the return spring 11.

[0043] 2. Initial State Debugging

[0044] Lightly press the crossbeam plate 1 to simulate a slight vibration condition. Observe whether the adjusting block 4 slides smoothly in the T-shaped limiting groove 3, whether the damping spring in the limiting damping shock absorber assembly 6 is compressed evenly, and whether the damping hydraulic rod provides stable damping force. If the inverted convex plate 8 is offset due to transportation or other reasons, the fixing bolt 9 can be loosened, the inverted convex plate 8 can be manually adjusted to the middle of the inverted convex groove 7 of the crossbeam plate 1, and then the bolt can be tightened to ensure that the reset spring 11 is in a naturally extended state.

[0045] 3. Automatic adjustment under vibration conditions

[0046] When the equipment vibrates during operation, the crossbeam plate 1 first bears the impact force and moves downward or sideways, causing the adjusting block 4 to slide within the T-shaped limiting groove 3. At this time:

[0047] The first stage of damping buffer: the two sets of limiting damping shock absorption components 6 (damping hydraulic rod + shock absorption spring) between the crossbeam plate 1 and the base plate 2 are compressed or stretched synchronously. The shock absorption spring absorbs the vibration kinetic energy, and the damping hydraulic rod consumes energy through the internal hydraulic oil flow, thus slowing down the vibration transmission speed.

[0048] The second stage of damping adaptive adjustment: When the adjusting block 4 slides, the damping rod 10 pulls or pushes the inverted convex plate 8 to move within the inverted convex groove 7. The return spring 11 is compressed or stretched, generating a reverse elastic force, which forces the adjusting block 4 to adjust its sliding amplitude. If the vibration intensity increases, the sliding distance of the adjusting block 4 increases, and the movement of the inverted convex plate 8 triggers the self-adjusting mechanism. The damping rod 10 and the return spring 11 work together to increase the resistance to the adjusting block 4, thereby increasing the overall damping force and suppressing excessive vibration. If the vibration weakens, the return spring 11 pushes the inverted convex plate 8 and the adjusting block 4 to reset, and the damping force automatically decreases, restoring the flexible buffer state.

[0049] 4. The protective role of restrictive institutions

[0050] When the adjusting block 4 slides to the edge of the T-shaped limiting groove 3, the limiting bolt 14 on the limiting plate 5 will contact the limiting slope groove 13 of the limiting block 12. As the adjusting block 4 continues to slide, the limiting bolt 14 pushes the limiting block 12 to slide into the groove along the slope of the limiting slope groove 13, compressing the limiting spring 15 until the limiting bolt 14 slides to the bottom of the slope groove. The limiting block 12 then locks the limiting bolt 14, preventing the adjusting block 4 from displacing excessively and avoiding the adjusting block 4 from dislodging from the T-shaped limiting groove 3. After the vibration weakens, the limiting spring 15 resets, pushing the limiting block 12 and the limiting bolt 14 back to their initial positions, and the adjusting block 4 can slide freely.

[0051] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
