Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a novel damping adjustable shock absorber. Background Technology

[0002] Early vehicles without shock absorbers experienced accelerated wear and tear on the frame, chassis, and engine due to continuous vibrations, leading to issues such as loose bolts, broken parts, and short service life. Shock absorbers mitigate impacts, reduce fatigue damage to the vehicle structure, and extend the overall durability of the vehicle. This is especially important for commercial vehicles, as frequent repairs significantly increase operating costs. As global automotive safety regulations have raised requirements for handling stability, braking distance, and collision safety, they have driven technological iterations in the industry.

[0003] Early automotive shock absorption systems primarily consisted of springs, but springs were prone to resonance, resulting in less than ideal damping performance. Subsequently, rocker arm shock absorbers became widely used, but due to their complex structure and susceptibility to damage, they were eventually replaced by simplified hydraulic shock absorbers. As the automotive market becomes increasingly homogenized, adjustable damping shock absorbers, as a core component for improving chassis feel, have become a focus of marketing and promotion. However, most current adjustable damping shock absorbers use a single orifice to control the flow of damping oil for damping, and cannot adjust the damping under different vibrations to achieve smoother damping, leading to reduced damping effectiveness and an increased risk of accidents. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a novel damping adjustable shock absorber, which aims to improve the problem of inaccurate quantitative measurement in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel damping adjustable shock absorber, comprising a cylinder body, the inner wall of which is connected to multiple connecting pipes, a hollow sleeve fixedly connected to the outer wall of each connecting pipe, a connecting ring fixedly connected to the outer wall of the hollow sleeve, a cylinder slidably connected to the inner wall of the connecting ring, a pushing ring fixedly connected to the outer wall of the cylinder, a steel ball disposed on the right side of the pushing ring, a spring fixedly connected to the inner wall of the hollow sleeve, a washer fixedly connected to the outer wall of the spring, a connecting block fixedly connected to the outer wall of the cylinder, and a safety mechanism fixedly connected to the inner wall of the cylinder body, the function of which is to protect the device when the internal pressure is too high.

[0006] As a further description of the above technical solution:

[0007] The safety mechanism includes a pressure relief pipe, the outer wall of which is fixedly connected to the inner wall of the cylinder. A safety valve housing is fixedly connected to the outer wall of the pressure relief pipe. Multiple baffles are slidably connected to the inner wall of the safety valve housing.

A temporary storage box is fixedly connected to the outer wall of the overflow pipe. An air hole is fixedly connected to the inner wall of the temporary storage box. A filter screen is fixedly connected to the inner wall of the air hole. A connecting block is fixedly connected to the outer wall of the temporary storage box.

[0008] As a further description of the above technical solution:

[0009] A piston plate is slidably connected to the inner wall of the cylinder, and a connecting column is fixedly connected to the outer wall of the piston plate.

[0010] As a further description of the above technical solution:

[0011] A connecting plate is fixedly connected to the outer wall of the piston plate, and a shock-absorbing spring is fixedly connected to the outer wall of the connecting plate.

[0012] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by driving the push ring to move inward, the steel ball moves inward, which in turn drives the pad ring to move inward, thus compressing the spring. At this time, the connecting pipe is connected, and the vibration force is transmitted to the connecting column through the piston plate, thereby compressing the damping oil in the upper cavity of the cylinder. The oil then flows from the connecting pipe into the lower cavity of the cylinder, absorbing the impact force during the flow. The number of connecting pipes is adjusted according to the magnitude of the impact force, thereby achieving the purpose of adjusting the damping according to the magnitude of the vibration, thus increasing the damping effect and reducing the possibility of accidents.

[0022] 2. In this utility model, when the impact force is too large, causing the internal pressure of the cylinder to exceed the warning value, the damping oil in the upper cavity of the cylinder causes the piston head to move upward, which in turn causes the baffle plate two to move upward, and then the spring two to be compressed. At this time, the damping oil in the upper cavity of the cylinder flows from the safety valve housing into the overflow pipe, and then into the temporary storage box to be collected and temporarily stored, thereby achieving the purpose of the protection device when the impact is too large.
