A flexible sound barrier and rigid mounting assembly, and a method of attaching to a vehicle. The sound barrier assembly includes a rigid substrate, and flexible noise barrier and decoupling layers. The decoupling and noise barrier layers are bonded, and an adhesive bonds the decoupling layer to the substrate. The decoupling and noise barrier layers are fixedly held in place by the substrate. The substrate can include slots that fit over mounting studs on the vehicle wall. The noise barrier and decoupling layers can include mounting holes that extend through both layers, where the mounting holes line up with the slots, and fit over the mounting studs. The assembly can be mounted on the mounting studs and stud fasteners can fit through a mounting hole without compressing the noise barrier and decoupling layers and sandwich the rigid substrate surrounding a slot between the stud fastener and the vehicle wall.

A vehicle roof lining includes a roof lining, a rail structure, a multifunction plate, and sleds. The rail structure is provided on both side edges of the roof lining. The multifunction plate is provided on the roof lining, with one edge of the multifunction plate being movable along the rail structure. The sleds are movable along inner portions of the rail structure and are fastened with one edge of the multifunction plate.

A fastening device for fastening a shielding part to a partnered fastening part, having: a sleeve with a through opening for a fastener; at least two bridging elements, which are equipped with outer regions in a radial direction for indirect or direct contact with the opposing outsides of the shielding part and are fastened to the sleeve with inner regions in the radial direction; a damping element is positioned between the bridging elements in an axial direction and outside of the sleeve in the radial direction, characterized in that the damping element is embodied as a spring element and has at least one spring arm, which is resiliently flexible in the radial direction and is equipped to cooperate in a supporting way with a hole rim of a hole of the shielding part.

A battery system for an electric vehicle includes a fixed cover, and a removable cover arranged over battery modules and a high voltage distribution system. The battery system includes a busbar arranged at least partially over a region of the battery modules and under the removable cover. The busbar includes a fixed section and a movable section, or a hinge, such that the busbar can be repositioned out of the way. The support tray includes a link between the fixed and movable sections. Floating fasteners, allowing at least one of radial float and axial float are used to secure the link to the support tray, thereby avoiding safety hazards and reducing the potential for short circuits in high voltage distribution systems or conductors thereof. The floating fasteners include a head, a neck, an engagement section, and a washer, which prevent removal from a component once installed.

Disclosed are systems and methods for coupling a first panel to a second panel via a fastener. The fastener having a cap, a shank, pair of wings, and one or more PIA-retention features. The shank defines a central longitudinal axis that is substantially perpendicular to the cap. The pair of wings is resiliently coupled to the shank at a distal end thereof. The pair of wings includes a first wing and a second wing, each angled away from the central longitudinal axis. In some examples, the one or more PIA-retention features can be a pair of whiskers resiliently coupled to the shank and angled away from the central longitudinal axis. Each of the pair of whiskers is substantially perpendicular to the central longitudinal axis. In other examples, the one or more PIA-retention features include a first fin resiliently coupled to and angled away from the first wing and a second fin resiliently coupled to and angled away from the second wing. The first fin and the second fin can retain the fastener relative to the first panel.

The present invention relates to a slide-topper anti-flapping and noise silencer device. The anti-flapping device features a folding hinge-like component and a pair of spring clamps. The folding hinge-like component has a pivotally connected rectangular upper panel and rectangular lower panel. The folding hinge-like component is secured along a leading edge of a slide-topper with the upper panel adhered to the top surface of the slide-topper and the lower panel adhered to the bottom surface of the slide-topper. Spring clamps are then used to secure the upper panel and the lower panel to the slide-topper. The anti-flapping device secures and stabilizes the leading edge of the slide-topper to eliminate flapping and any other associated noises.

In accordance with an embodiment, a noise reduction device includes a housing; and a slit located inside the housing and having a unit cell located therein, the unit cell comprising a sound absorbing layer configured to absorb noise generated from a sound source inside the housing, and a meta-material panel layer located on one surface of the sound absorbing layer, the meta-material panel layer comprising a sound meta-material.

A vehicle undercover structure, includes a vehicle body frame including a first side rail and a second side rail spaced from each other in a width direction of a vehicle; a front undercover mounted on the front of the vehicle body frame; a rear undercover mounted on the rear of the vehicle body frame; and a main undercover disposed between the front undercover and the rear undercover, wherein the main undercover covers a moving component which is movable between an upper limit position and a lower limit position on the vehicle body frame.

A hollow chamber blocking tool includes: a first blocking tool having a first foamable base material on a first holder plate; and a second blocking tool having a second foamable base material on a second holder plate. The first blocking tool includes a steel plate fixing portion locked to a steel plate. The second blocking tool includes an integrated portion locked to the steel plate fixing portion. The second holder plate includes a rotating portion rotatably connected to the first blocking tool.

A single piece retention clip for attaching a foam part to a substrate is disclosed. The retention clip includes a pair of spaced apart and opposed curvilinear retention clip arms, a planar foam part retaining member, and a bridge having a first and second ends. The first bridge end extends from the planar foam part retaining member. The clip arms are flexibly attached to the second bridge end. The insulation part is captured between the planar foam part retaining member and the clip arms, prior to attachment of the clip to the substrate. An operator-usable handle to facilitate clip insertion and removal relative to the substrate may be formed on the foam part retaining member. Each clip arm includes a body having wide and narrow parts. The wide part of each of clip arm is attached to the bridge. A hook is formed at the narrow part of each arm.
