摘要:
A headlamp assembly for a motor vehicle having a light source, a chamber that receives the light source and a cooling channel for removing heat from the chamber. A conductive wall and an insulating wall cooperate to define the chamber and the channel. The conductive wall has a substantially higher thermal conductivity than the insulating wall to promote the heat exchange between the chamber and the cooling channel and to reduce heat exchange between the cooling channel and the relatively hot engine compartment.

A headlamp assembly for a motor vehicle including a lens and a housing that cooperate to define an inner chamber that is generally isolated from the atmosphere. A heat sink includes a fin portion that extends from the inner chamber so as to be exposed to ambient air. A light source is located within the inner chamber and is supported on a base portion of the heat sink. The heat sink conducts heat from the light source to air located exterior of the chamber.

A vent assembly that can be concealed when in a closed configuration is provided in one embodiment, the vent assembly comprises a base member and a guide member secured to a mounting surface of a duct or other passageway. A flexible rod is fixedly attached to the base member and slideably disposed within a channel defined by the guide member. A panel is disposed on or around the flexible rod and between the base and guide members. An actuator is able to deform the rod such that the panel moves away from the terminal opening of the duct, thereby opening the vent. A fluid distribution system incorporating vent assemblies in accordance with the present invention is also provided.

A circuit board assembly is disclosed comprising a pair of three-dimensional substrates having integral, metallized connectors. The connector of the first substrate protrudes therefrom, while the connector of the second substrate is recessed therein. The geometries of the protruding connector and the recessed connector are different such that they deform when assembled to provide an electrical connection and a detachable physical connection. In one embodiment, the recessed connector has a parabolic cross-section and the protruding connector has a circular cross-section. A flexible molded edge connector for the circuit board assembly is also disclosed.

An electronic assembly includes a flexible multilayer substrate having integral electrically-conductive traces that also includes, as a lowermost layer, a metal foil. A plurality of uppermost layers, likewise including a metal foil, form a thin barrier member that is sealingly attached to the substrate's other layers. In this manner, a plurality of electronic components, mounted on the substrate's other layers so as to be electrically interconnected with the traces before sealingly attaching the barrier member, are encapsulated within metal foil to provide an environmentally-sealed assembly featuring improved resistance to moisture diffusion and penetration/permeation of other substances characteristic of the assembly's service environment into the assembly. A filler material, also encapsulated within the metal foil, is operative to neutralize a predetermined amount of a penetrant, further improving the operability and service life of the assembly. Preferably, a relatively-rigid polymeric material is formed in touching contact with the substrate, as by overmolding the plastic material on the environmentally-sealed assembly, to thereby provide a plastic part incorporating the assembly.

There is disclosed herein an intake manifold for a port-injected internal combustion engine, comprising: a manifold body 10 having an interior plenum 12, and a runner 14 extending outward from the manifold body 10, wherein the runner 14 has a distal end 16 and a passage 18 therethrough in communication with the plenum 12. The distal end 16 of the runner 14 has a socket 20 therein into which an EFI 50 may be operatively mounted, and a first keying feature 22 formed therein for aligning the EFI in a first predetermined orientation when the EFI is engaged with the socket 20 and keying feature 22. The manifold may further include a second keying feature 42 formed in the runner end 16 for aligning a coil-on-plug spark plug ignition coil 80 in a second predetermined orientation when the coil 80 is engaged with the second keying feature 42. The manifold may also include a means 30 for electrically connecting a signal source to the injector 50 and/or coil 80, arranged such that the EFI/coil may each be mechanically and electrically engaged with the manifold and signal source in essentially a single step.

Conductors supported integrally with engine structure such as air intake manifolds and the like provide interconnection between engine components without the need for separate conventional wiring harnesses. The conductors take their mechanical strength from the underlying physical object and thus can be lighter than a freestanding harness. Connectors allow traces to continue across points of mechanical interface between structural components and allow wiring of engine components to be accomplished in the same operation as their physical assembly.

A braking unit is provided. In one embodiment, the braking unit comprises a base member, a guide member, a flexible rod, an actuator adapted to induce deformation of the rod, and a brake pad. One end of the flexible rod is fixedly attached to the base member while another end is slideably disposed within a passageway defined by the guide member. The brake pad is positioned adjacent the flexible rod such that deformation of the rod causes lateral movement of the brake pad. The braking unit can be incorporated into disc and drum-type braking assemblies and systems.
