Description

Technical Field

[0001] This utility model relates to the field of shock absorber technology, specifically to a high-efficiency vibration damping and recovery valve system structure. Background Technology

[0002] In many fields such as automobiles and construction machinery, where vibration damping systems are crucial for ensuring smooth and comfortable operation, shock absorbers, as core components, directly affect the overall working condition and service life of the equipment. Shock absorbers primarily achieve vibration damping and buffering by converting and dissipating the vibration energy generated during vehicle movement or equipment operation into heat energy through the coordinated action of their internal valve system. The recovery valve system, as an important component of the shock absorber, plays a key role in its working cycle. When a vehicle or equipment is subjected to external forces, the shock absorber is compressed. Subsequently, during the rebound process, the recovery valve system controls the flow of hydraulic fluid to regulate the rebound speed and ensure smooth equipment reset.

[0003] However, some current shock absorbers employ a recovery valve system structure with significant defects. These recovery valve systems lack effective offsetting structures and, when working together with the compression valve system, directly bear the impact force from the compression valve system for extended periods. Due to the lack of a buffer mechanism, this impact force causes frequent and severe impacts on critical components such as valve plates and valve seats, resulting in damage such as dents and cracks on their surfaces. This, in turn, affects the sealing performance of the valve plates and the normal operation of the valve system. Over time, the performance of the recovery valve system gradually declines, making it impossible to accurately control the oil flow, significantly reducing the vibration damping effect of the shock absorber. More seriously, this continuous impact drastically shortens the service life of the recovery valve system, leading to premature failure of the shock absorber. Therefore, we propose a high-efficiency vibration-damping recovery valve system structure to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a highly efficient vibration damping and recovery valve system structure, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A high-efficiency vibration damping and recovery valve system structure includes a shock absorber body, an inner cylinder inside the shock absorber body, a piston rod on the inner cylinder, a compression valve system on the piston rod, a recovery valve system body on the bottom inner wall of the inner cylinder, multiple support blocks fixedly connected in a ring on the inner wall of the inner cylinder, each support block having a cavity, and grooves on both sides of the inner wall of the cavity, with guide rods welded between the two sides of the grooves, and a connecting block slidably connected to two guide rods in the same cavity, with a spring fixedly connected between the bottom of the connecting block and one side of the corresponding groove, the spring being movably sleeved on the corresponding guide rod, and a force transmission rod fixedly connected to the top of the connecting block, the top of the force transmission rod extending to the outside of the corresponding support block and fixedly connected to a force transmission block, the top of the force transmission block being in movable contact with the bottom of the compression valve system.

[0007] Furthermore, a circular hole is provided on the top inner wall of the cavity, and the inner wall of the circular hole is slidably connected to the outer side of the corresponding force transmission rod.

[0008] Furthermore, a sealing ring is fixedly connected to the top of the support block, and the sealing ring is slidably connected to the corresponding force transmission rod.

[0009] Furthermore, a sealing sleeve is fixedly connected to the top of the shock absorber body, and the sealing sleeve is slidably connected to the piston rod.

[0010] Furthermore, the connecting block has two guide holes, and the connecting block is slidably connected to the corresponding guide rod through the guide holes.

[0011] Compared with the prior art, this utility model provides a high-efficiency vibration reduction and recovery valve system structure, which has the following beneficial effects:

[0012] This invention addresses the issue that during the operation of the shock absorber, when the compression valve system is impacted and moves downwards, its bottom comes into contact with the force transmission block on the support block. The pressure of the compression valve system on the force transmission block is transmitted to the connecting block through the force transmission rod. After receiving the pressure transmitted by the force transmission rod, the connecting block moves downwards along the guide rod and compresses the spring. The elastic restoring force generated by the spring applies an upward force to the connecting block. This force counteracts the downward pressure transmitted by the compression valve system to the connecting block through the force transmission rod. Through this interaction of forces, the spring effectively buffers the impact force of the compression valve system on the restoring valve system body, achieving effective buffering of the impact force of the compression valve system, reducing the impact damage to the restoring valve system body, thereby extending the service life of the restoring valve system body and the shock absorber body, and improving the overall performance and reliability of the shock absorber body.

[0018] 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. Example

[0019] like Figure 1-4As shown, an embodiment of this utility model proposes a high-efficiency vibration damping and recovery valve system structure, including a shock absorber body 1, an inner cylinder 2 inside the shock absorber body 1, a piston rod 3 on the inner cylinder 2, a compression valve system 4 on the piston rod 3, a recovery valve system body 5 on the bottom inner wall of the inner cylinder 2, multiple support blocks 6 fixedly connected in a ring on the inner wall of the inner cylinder 2, a cavity 7 opened on the support block 6, grooves 8 opened on both sides of the inner wall of the cavity 7, a guide rod 9 welded between the two sides of the inner wall of the groove 8, a connecting block 10 slidably connected to two guide rods 9 on the same cavity 7, a spring 11 fixedly connected between the bottom of the connecting block 10 and one side of the inner wall of the corresponding groove 8, the spring 11 movably sleeved on the corresponding guide rod 9, a force transmission rod 12 fixedly connected to the top of the connecting block 10, the top end of the force transmission rod 12 extending to the outside of the corresponding support block 6 and fixedly connected to a force transmission block 13, the top of the force transmission block 13 movably contacting the bottom of the compression valve system 4, during the operation of the shock absorber, the compression valve system 4 will be subjected to the action of piston rod 3 and external impact force, generating large vibration and impact force. When the compression valve system 4 moves downward under impact, its bottom will make active contact with the force transmission block 13 on the support block 6. The pressure of the compression valve system 4 on the force transmission block 13 will be transmitted to the connecting block 10 through the force transmission rod 12. After being subjected to the pressure transmitted by the force transmission rod 12, the connecting block 10 will move downward along the guide rod 9 and compress the spring 11. The elastic restoring force generated by the spring 11 will exert an upward force on the connecting block 10. This force counteracts the downward pressure transmitted by the compression valve system 4 to the connecting block 10 through the force transmission rod 12. Through this interaction of forces, the spring 11 effectively buffers the impact force of the compression valve system 4 on the recovery valve system body 5, realizing effective buffering of the impact force of the compression valve system 4, reducing the impact damage to the recovery valve system body 5, thereby extending the service life of the recovery valve system body 5 and the shock absorber body 1, and improving the overall performance and reliability of the shock absorber body 1.

[0020] In some embodiments, a circular hole 15 is provided on the inner wall of the top of the cavity 7. The inner wall of the circular hole 15 is slidably connected to the outer side of the corresponding force transmission rod 12. The force transmission rod 12 serves as a connection.

[0021] In some embodiments, a sealing ring 14 is fixedly connected to the top of the support block 6, and the sealing ring 14 is slidably connected to the corresponding force transmission rod 12.

[0022] In some embodiments, a sealing sleeve 16 is fixedly connected to the top of the shock absorber body 1, and the sealing sleeve 16 is slidably connected to the piston rod 3, which can effectively prevent oil from leaking out from the connection between the piston rod 3 and the top of the shock absorber body 1.

[0023] In some embodiments, the connecting block 10 has two guide holes, and the connecting block 10 is slidably connected to the corresponding guide rod 9 through the guide holes. The cooperation between the guide holes and the guide rod 9 provides precise guidance for the movement of the connecting block 10.

[0024] In operation, the compression valve system 4 is subjected to impact forces from the piston rod 3 and external forces, resulting in significant vibration and impact. When the compression valve system 4 moves downwards under impact, its bottom comes into contact with the force transmission block 13 on the support block 6. Since the force transmission block 13 is fixedly connected to the connecting block 10 via the force transmission rod 12, and the connecting block 10 is slidably connected to the guide rod 9 within the cavity 7 of the support block 6, the pressure of the compression valve system 4 on the force transmission block 13 is transmitted to the connecting block 10 via the force transmission rod 12. After receiving the pressure transmitted by the force transmission rod 12, the connecting block 10 moves downwards along the guide rod 9. During the movement of the connecting block 10, the corresponding spring 11 is compressed. The elastic restoring force generated by the spring 11 applies an upward force to the connecting block 10. This force counteracts the downward pressure transmitted to the connecting block 10 by the compression valve system 4 through the force transmission rod 12. Through this interaction of forces, the spring 11 effectively buffers the impact force of the compression valve system 4 on the restoring valve system body 5, effectively buffering the impact force of the compression valve system 4, reducing the impact damage to the restoring valve system body 5, thereby extending the service life of the restoring valve system body 5 and the shock absorber body 1, and improving the overall performance and reliability of the shock absorber body 1.
