Description

Technical Field

[0001] This utility model relates to a shock-absorbing component, specifically to an adjustable damping shock absorber with a positive bottom end. Background Technology

[0002] Adjustable damping shock absorbers play a significant role and offer numerous advantages in vehicles. They can precisely adjust the damping force according to different road conditions and driving needs. When driving on bumpy roads, the damping can be appropriately softened to effectively filter vibrations, reduce body sway, and make the ride more comfortable. When driving, the damping can be stiffened to enhance suspension support, improve handling stability, and enable the vehicle to handle various actions more steadily, reducing the risk of body roll. They can meet the smooth and comfortable requirements of daily urban commuting as well as the handling needs under special road conditions, greatly improving the overall performance of the vehicle, extending the service life of components such as the vehicle's suspension system, and making the driving experience more comfortable.

[0003] In the prior art, 202020720582.1 discloses a durable damping shock absorber, comprising a damping shock absorber body and an upper support. The upper support is provided at the upper end of the damping shock absorber body, and a support cylinder is provided on the outer wall of the damping shock absorber body. The support cylinder is parallel to the position of the damping shock absorber body, and an auxiliary support rod is inserted inside the support cylinder. The auxiliary support rod is slidably connected to the support cylinder, and the upper end of the auxiliary support rod is fixedly connected to the bottom of the upper support. A side support plate is vertically provided on the outer wall of the damping shock absorber body, and the side support plate is connected to the damping shock absorber body by welding. This durable damping shock absorber adopts a structural design such as an auxiliary support rod, a support cylinder, and a side support plate, which can greatly strengthen the cylinder wall of the damping shock absorber body, preventing it from tilting or bending, and preventing it from denting or bulging, thereby making the damping shock absorber body more durable.

[0004] In existing technologies, the design of auxiliary struts, support cylinders, and side support plates can greatly strengthen the cylinder wall of the damping shock absorber body, which can prevent it from tilting and bending. However, the damping control method of the shock absorber using small orifice throttling affects the working effect of the shock absorber. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides an adjustable damping shock absorber with upright bottom adjustment.

[0006] This utility model is achieved using the following technical solution: a bottom-mounted adjustable damping shock absorber, comprising a shock absorber and a handle. The shock absorber has an internal movable damping space, within which a piston rod is installed. A piston assembly is mounted on one side of the piston rod, and a push rod for lifting the piston rod is located on one side of the piston rod. An assembly end is located on one side of the push rod, and an assembly hole for further assembly is provided on the assembly end. A helical telescopic rod is assembled within the assembly hole, and a handle is located on one side of the helical telescopic rod. A damping component is located inside the shock absorber, and the damping component for further damping is a spring seat. A floating valve is located on one side of the push rod, and a floating valve return spring is located between the spring seat and the floating valve.

[0007] The shock absorber has a damping hole on its outer wall, and a sealing component, namely a top rod sealing ring, is provided between the top rod and the spiral telescopic rod.

[0008] A stop component is provided on one side of the handle, and the stop component is a stop screw, which is distributed on both sides of the handle.

[0009] A shock-absorbing spring is provided on one side of the piston assembly, a guide sealing component is provided on the shock absorber, and a handle tube assembly is provided between the shock absorber and the shock-absorbing spring.

[0010] An aluminum outer tube is provided between the shock absorber and the shock absorber spring, and a high-pressure chamber is provided between the piston rod and the shock absorber in the movable shock absorption space.

[0011] The high-pressure chamber is filled with oil, a one-way valve is provided on one side of the high-pressure chamber, and an oil return hole is provided on one side of the piston rod.

[0012] The shock absorber is equipped with a locking component inside, which is a stable locking component.

[0013] The spring seat is provided with a stop part, which is a spring stop screw.

[0014] Compared to existing technologies, this shock absorber features two throttling orifices, allowing for greater adjustment flexibility and better adaptability. The cleverly designed pushrod and floating valve cleverly avoid oil circuit circulation, meeting oil flow requirements under any operating condition. The high-pressure chamber oil, combined with the check valve and return oil orifice, forms a highly efficient hydraulic system. The synergistic effect of the piston assembly and shock absorber spring significantly improves shock absorption stability. The dual protection design of the pushrod seal ring and guide seal greatly reduces the risk of oil leakage, ensuring long-term reliability. The stop screw and stabilizing locking components enhance the anti-loosening ability of key components, improving overall structural safety and achieving a balance between damping adjustment accuracy and durability.
