AI Technical Summary

Technical Problem

The existing welcome pedal hinge's moving shaft causes noise during use due to lubrication failure, and the exposed structure affects the user experience and cannot be hidden.

Method used

Design a bearing for use in welcome pedal hinges, comprising a base layer, a copper mesh layer, and a self-lubricating layer. The self-lubricating layer, made of polytetrafluoroethylene, improves lubrication performance, and the copper mesh layer enhances the bonding force between the base layer and the self-lubricating layer, thereby reducing the coefficient of friction and noise.

Benefits of technology

It reduces the coefficient of friction, decreases noise, protects the bearing bores, prevents wear and corrosion, lowers the maintenance cost of the welcome pedals, and improves the user experience.

Abstract

A bearing for a welcome pedal hinge, the welcome pedal hinge comprising a body, two cantilever arms, and a bearing hole. The bearing for the welcome pedal hinge includes a bearing body and rolled edges. The bearing body is inserted into the bearing hole, and the two rolled edges are arranged opposite each other. The bearing includes a substrate layer, a copper mesh layer disposed on the substrate layer, and a self-lubricating layer disposed on the copper mesh layer. The self-lubricating layer is mainly made of polytetrafluoroethylene. This bushing, by placing the bearing in the bearing hole, not only reduces the coefficient of friction and noise, but also protects the bearing hole from wear and rust, thus preventing the need to replace the welcome pedal and causing significant waste.
