AI Technical Summary

Technical Problem

Existing fuel pipe mounting structures in vehicles are prone to damage and displacement during impacts, such as rear-end collisions, leading to potential damage to the fixing points and connected hoses due to uneven load distribution and bracket detachment.

Method used

A fuel pipe mounting structure featuring a bracket with an elongated hole that allows the bracket to slide in the fore-and-aft direction within the vehicle, reducing load on fixing points and preventing detachment, using a fastener that locks into the elongated hole to maintain stability during impacts.

Benefits of technology

The structure effectively maintains the fuel pipes' stability and prevents damage to the fixing points and connected hoses by allowing the bracket to slide smoothly, reducing the risk of detachment and ensuring the fuel pipes remain securely attached to the vehicle body even under impact.

Abstract

This mounting structure for mounting a filler pipe (11), which connects an oil supply port (41) of a vehicle (100) and a fuel tank (15), and a breather pipe (13) to a vehicle body (17) comprises a bracket (60) fixed to the filler pipe (11) and the breather pipe (13). The bracket (60) has a long hole (61) extending in the vehicle front-rear direction, and is fixed to the vehicle body (17), so as to be slidable in the vehicle front-rear direction within a range in the length direction of the long hole (61), by a fastening bolt (71) inserted into the long hole (61) and fastened to the vehicle body (17).
