Abstract
This disclosure details electrified vehicles that are equipped with pass through assemblies for structurally reinforcing and sealing battery packs. An exemplary pass through assembly includes clean-side component and a dirty-side component. The clean-side component is positioned primarily inside the battery pack, and the dirty-side component engages the clean-side component and extends to a location outside of the battery pack for interfacing with a component of the vehicle underbody. A seal of the pass through assembly is positioned between the clean-side component and the dirty-side component and is configured to block the ingress of water, dirt, and other potential contaminants.
Claims20
A pass through assembly for a battery pack, comprising:
- a clean-side component including a pipe and a first flange protruding from the pipe;
- a dirty-side component including a stud and a second flange protruding from the stud, wherein the stud engages a first portion of the pipe and the second flange contacts a second portion of the pipe;
- and
- a seal arranged between the clean-side component and the dirty-side component.
A pass through assembly for a battery pack, comprising:
- a clean-side component including a pipe and a first flange protruding from the pipe;
- a dirty-side component including a stud and a second flange protruding from the stud, wherein the stud engages a portion of the pipe;
- and
- a seal arranged between the clean-side component and the dirty-side component,
- wherein the clean-side component includes a shoulder that extends above the first flange,
- wherein the second flange of the dirty-side component abuts against the shoulder.
A pass through assembly for a battery pack, comprising:
- a clean-side component including a pipe and a first flange protruding from the pipe;
- a dirty-side component including a stud and a second flange protruding from the stud, wherein the stud engages a portion of the pipe;
- and
- a seal arranged between the clean-side component and the dirty-side component,
- wherein the seal is established by an inverted flange that protrudes from a bottom face of the second flange.
A pass through assembly for a battery pack, comprising:
- a clean-side component including a pipe and a first flange protruding from the pipe;
- a dirty-side component including a stud and a second flange protruding from the stud, wherein the stud engages a portion of the pipe;
- and
- a seal arranged between the clean-side component and the dirty-side component,
- wherein the seal is embedded within the second flange and is either single sided for sealing against one structure or double sided for sealing against two structures.
A pass through assembly for a battery pack, comprising:
- a clean-side component including a pipe and a first flange protruding from the pipe;
- a dirty-side component including a stud and a second flange protruding from the stud, wherein the stud engages a portion of the pipe;
- and
- a seal arranged between the clean-side component and the dirty-side component,
- wherein a first section of the stud that extends below the second flange engages the portion of the pipe, and comprising a nut received over a second section of the stud that extends above the second flange.
An electrified vehicle, comprising:
- a vehicle underbody including a floor pan;
- a battery pack mounted beneath the floor pan;
- a pass through assembly including a clean-side component and a dirty-side component;
- the clean-side component extending from a location inside the battery pack and including a portion at least partially exposed within a first hole formed in a cover of the battery pack;
- and
- the dirty-side component connected to the clean-side component and extending through a second hole formed in the floor pan.
