A cover for integrated power electronics (IPE), the cover including a first sheet, a second sheet bonded to the first sheet by at least one joining point in a perimeter region, a cavity defined between the bonded first sheet and second sheet, wherein the perimeter region seals the cavity, and a filler material disposed within the cavity.

A heat insulating member includes a wall member. The wall member includes a high-density portion provided at one end edge in a direction orthogonal to a thickness direction of the wall member and having density of above 0.45 g/cm.sup.3 and a low-density portion provided midway in the direction orthogonal to the thickness direction, having heat-insulating properties, and having density of 0.45 g/cm.sup.3 or less. The high-density portion is provided over the entire one end edge and the thickness of the high-density portion is thinner than that of the low-density portion.

A cover is provided for placement in a front/rear compartment of a motor vehicle. The cover is substantially made up of a frame and a covering attached to the frame. The covering is formed from a thin, flexible, in particular, skin-like material. The cover can be mounted in the front/rear compartment such that the covering covers at least one section of the front/rear compartment and/or one component situated therein.

The present invention relates to a heat shield for shielding of hot areas, such as hot areas of a combustion engine as well as a part that is shielded with such a heat shield. The heat shield for shielding of hot areas, e. g. of a combustion engine, with at least one metal sheet layer, characterized in that the insulating layer comprises a metallic grid, which is embedded into a fiber mat.

A vehicle frame assembly includes a plurality of members, a tray, at least one insulation member, and at least one battery. The plurality of members define a first void. The tray is coupled to at least one member of the plurality of members. The tray defines a second void. The at least one insulation member is disposed within the first void or the second void. The at least one battery is disposed within the first void and the second void.

Provided is a work vehicle in which components such as a headlamp are less likely to be affected by heat. The work vehicle includes a running vehicle body which includes running devices and to which a work machine can be replaceably connected; an engine mounted on the running vehicle body and serving as a drive source for the running devices and the work machine; a bonnet covering the engine; a headlamp attached to a front portion of the bonnet; a muffler arranged below the headlamp in an internal space of the bonnet; and a heat shield member arranged between the headlamp and the muffler.

A sound absorber/insulator in a motor vehicle is constructed of outer layer nonwoven scrims, perforated films, and a fill material core, which are typically fibers or foams. Fibers could be of a nonorganic nature such as glass, or an organic one like polyester or cotton. Foams could be of open cell polyurethane chemistry. The materials are enveloped in a thermoforming process wherein all layers are substantially adhered to each other. The fill material is responsible for sound attenuation whereby a higher weight input provides additional attenuation benefit. Specialized technical nonwoven scrims can also be used to enhance the sound attenuation where required. Increasing absorption properties by adding weight or using highly technical nonwovens is costly and results in a weight penalty. Perforated films of certain thicknesses, hole sizes, and hole densities significantly enhance sound attenuation properties of an absorber and do so with no changes to the manufacturing process, a minimal increase in weight, and at a substantially lower cost. The films can be positioned in different locations throughout an insulator, depending on absorption requirements.

The invention relates to a manufacturing method for a crash frame of a battery compartment for electric drive vehicles by using metallic sheets which are arranged on top of one another and fixed together and which form in a following step a space by using an inner active media forming process to create walls of a crash frame whereby the space works as a deformation space to protect the battery modules inside the battery compartment against an impact. The invention further relates to the use of the crash frame for a battery compartment.
