Problems solved by technology

Automobiles can include bulkheads constructed of certain materials with considerable weight, which can be difficult to install
Furthermore, such bulkheads may be limited in their ability to attenuate noise from the engine compartment, which could be considered a nuisance to occupants in the passenger compartment

example 1

[0095] Example 1. A bulkhead configured to be coupled to an automobile frame between an engine compartment and a passenger compartment, the bulkhead comprising:

[0096] a support structure comprising a body and at least one reinforcing insert embedded within at least a portion of the body;

[0097] a thermal component positioned on a side of the support structure configured to be disposed proximate to the nacelle;

[0098] at least one installation section; and

[0099] an acoustic component positioned between the support structure and the thermal component,

[0100] wherein the acoustic component defines a plurality of openings on a side of the acoustic component disposed proximate to the thermal component,

[0101] wherein the acoustic component comprises a plurality of cells extending in a first direction from the support structure towards the thermal component,

[0102] wherein each cell of the plurality of cells defines a first volume in fluid communication with at le...

example 2

[0104] Example 2. The bulkhead of example 1, wherein the plurality of cells are arranged in rows,

[0105] wherein the longitudinal direction of the bulkhead is perpendicular to the first direction,

[0106] wherein the second direction is perpendicular to said longitudinal direction and said first direction,

[0107] wherein the respective dimension along said longitudinal direction corresponds to the length of each cell and the length of each row, and

[0108] Wherein the corresponding dimension along the second direction corresponds to the height of each cell and the height of each row.

example 3

[0109] Example 3. The bulkhead of example 2, wherein the plurality of rows are arranged along the longitudinal direction, and

[0110] Wherein each row of the plurality of rows extends along the second direction.

Abstract

A bulkhead (110) for separating an engine compartment (112) and a passenger compartment (114) including a support structure (320) including at least one reinforcement member (324) and a body (322) supported by the reinforcement member (324), a thermally insulative component (330) supported by the support structure (320), and an acoustic resonator (370) defining a plurality of openings that extend along a first direction from the thermally insulative component (330) toward the first resonator side and terminate at a location between the first resonator side and the second resonator side. The acoustic resonator (370) includes a plurality of cells that each defines a respective first open volume that is in fluid communication with at least one of the plurality of openings.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Indian Patent Application No. 1526 / DEL / 2015 filed May 28, 2015, the entire contents of which are incorporated herein by reference. Background technique [0003] Conventional automobiles include an automobile frame that defines the various compartments of the automobile. Two such compartments are the engine compartment and the passenger compartment defined adjacent to each other by the vehicle frame. Since the engine compartment houses the engine of the car, a large amount of heat and noise may be generated during operation of the engine and possibly transmitted to the passenger compartment. Automobiles may include bulkheads constructed from certain materials that have considerable weight, which can be difficult to install. Furthermore, such bulkheads may be limited in their ability to attenuate noise from the engine compartment, which may be considered a nuisance to occupants in th...
