AI Technical Summary

Technical Problem

Conventional battery pack fixing structures face misalignment issues due to variations in part precision, leading to increased size and weight of cylindrical components, which occupy valuable internal space and risk water ingress.

Method used

A battery pack fixing structure using a cylindrical member with an attached grommet made of an elastic material, featuring a curved connecting piece and stoppers, allows for radial displacement and secure attachment to a floor panel, reducing the cylindrical member's size and weight while preventing water ingress.

Benefits of technology

The structure effectively absorbs misalignment without enlarging the cylindrical member, reduces weight and space occupation, and ensures secure, watertight fixation of the battery pack.

Abstract

To provide a battery pack fixing structure that is advantageous for smoothly fixing the battery pack to the floor panel without increasing the size of the cylindrical member. [Solution] The fixing structure 28 for fixing the battery pack 10 to the floor panel 22 includes a cylindrical member 30 that penetrates vertically from the opening 1404 in the bottom wall 1402 of the tray 14 of the battery pack 10 through the opening 1604 in the upper wall 1602 of the cover 16 of the battery pack 10 to the lower surface of the floor panel 22, a bolt 32 that is inserted inside the cylindrical member 30 and fastens the battery pack 10 to the floor panel 22, and a grommet 34 made of an elastic material that is attached to the upper part of the cylindrical member 30 and connected to the edge of the opening 1604 in the upper wall 1602 of the cover 16.
