AI Technical Summary

Technical Problem

When faced with large and heavy components, the buffer mechanism of traditional transport trolleys suffers from lag in deformation of rubber pads and springs under dynamic loads, resulting in loss of buffering effect. This causes the components to directly bear impact loads, posing a risk of structural damage.

Method used

A buffer mechanism was designed. The sliding sleeve slides when the support plate is pressed down. The fixed rod compresses the spring for the first buffering. The support rod and the damping rod 1 and the spring 2 provide the second buffering. The hinge rod 1 and the hinge block rotate to provide the third buffering. Combined with the clamping mechanism, the parts are clamped by the threaded rod and the clamping plate to ensure that damage is avoided during violent collisions and shaking.

Benefits of technology

This effectively avoids deformation and wear of parts caused by violent collisions and shaking, reduces the risk of damage, and improves the safety and efficiency of the transportation process.

Abstract

This utility model discloses a buffer mechanism for an automotive parts transport trolley, relating to the field of automotive parts transportation technology. The utility model includes a support plate with protective boxes installed on both the left and right sides of the support plate, and further includes: a buffer mechanism located on top of a fixed plate; and a clamping mechanism located on top of the support plate. Specifically, the weight of the boxes causes the support plate to press down, causing the sliding sleeve to slide outside the fixed rod, completing the first buffer. Subsequently, the pressure is transmitted through the support plate to the support rod, then to damping rod one and spring two, achieving a second buffer. When the pressure is greater, it is transmitted through the support plate to the bottom of the hinge block, then to hinge rod one. When the support plate presses down, its bottom pushes the sliding blocks away from each other, simultaneously squeezing damping rod two and spring three, completing a third buffer. This prevents automotive parts from deforming due to collisions and shaking, reducing the risk of damage to the parts.
