Method used

[0041] Primary coupler 342 may be attached to any or all of support structure 320, thermal component 330, or acoustic component 350 by structural adhesive or other type of adhesive. Alternatively, the main coupler may include a reinforcing insert (not shown) extending in the longitudinal direction from the coupler body 342a towards the bulkhead 110 . Such an extension member may be formed with a support structure 320 during the injection molding process. Specifically, the extension may be overmolded as an insert in the body 322 of the support structure 320 and provide improved structural rigidity to the bulkhead 110 . As shown in FIG. 3 , the thickness of the main coupler 342 may define the thickness of the bulkhead 110 along the first direction A. As shown in FIG. It should be appreciated that the coupler body 342a may extend in the first direction less than the combined thickness of the support structure 320 , the acoustic component 350 and th...

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.

Example

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

[0096] A support structure, which includes a main body and at least one reinforcing insert embedded in at least a part of the main body;

[0097] A thermal component, which is positioned on the side of the support structure configured to be arranged close to the engine compartment;

[0098] At least one installation part; and

[0099] An acoustic component, which is positioned between the support structure and the thermal component,

[0100] Wherein the acoustic component defines a plurality of openings on a side surface of the acoustic component arranged close to the thermal component,

[0101] Wherein the acoustic component includes a plurality of units extending from the support structure toward the thermal component in a first direction,

[0102] Wherein each cell of the plurality of cells defines a first volume in fluid communication with at least one of the plurality of openings,

[0103] The cross-sectional area of each of the plurality of openings is smaller than the cross-sectional area of the corresponding first volume.

Example

[0104] Example 2. The bulkhead according to example 1, wherein the plurality of units are arranged in a plurality of rows,

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

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

[0107] Wherein the corresponding dimension along the longitudinal direction corresponds to the length of each unit and the length of each row, and

[0108] The corresponding size along the second direction corresponds to the height of each unit and the height of each row.

Example

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

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