A bumper cross member for a motor vehicle, having a crossmember extending transversely to the longitudinal axis of the vehicle, and two crashboxes connected thereto and designed as hollow chamber sections. Each crashbox is connected with its end facing away from the vehicle to the crossmember in a respective end section thereof, and may be connected, with its end facing the vehicle, to a structural component of the vehicle. The crashboxes are supported with their end faces only in sections on the rear side of the crossmember, in particular such that the support is continuous or at least substantially continuous either in the upper and lower end-face areas, or in the two lateral end-face areas, while support of the other end-face areas is provided only in sections or absent. The distance between the end-face areas of the crashboxes, which are unsupported on the crossmember, is set from the rear side of the crossmember, such that only after a first phase of energy absorption with deformation of the crashbox is the end face facing the crossmember supported over its whole surface on the rear side of the crossmember.

Bumper crossbeam for a motor vehicle

A battery housing for a motor vehicle comprising a base part having a base plate and a cover part having a cover plate. The base part and the cover part delimit a receptacle volume for receiving at least one battery module. The two plates are spaced apart by at least one spacer which is disposed inside the receptacle volume and is supported on the two plates. In the region of at least one support of the spacer, the respective plate has a cut-out. The spacer has an insertion portion which projects into the cut-out and is secured on this plate. The insertion portion projects into the cut-out to the maximum extent that the end face of the insertion portion lies flush with the outer side of the plate.

Battery housing comprising a spacer

A battery housing for a motor vehicle comprising a base part having a base plate and a cover part with a cover plate. The base part and the cover part delimit an accommodation volume for accommodating at least one battery module. The plates are spaced apart by at least one spacer arranged inside the receiving volume and supported on both plates, in that the spacer is supported on at least one of the two plates with its end face. In the region of this support, the plate has an opening. The end face of the spacer extends circumferentially over the edge of the opening in the radial direction inward projecting into the plane of the support of the end face on the plate. The spacer is fastened on this plate.

A bumper crossmember for a motor vehicle having a crossmember extending transversely to the longitudinal axis of the vehicle and two crashboxes connected thereto. Each crashbox is connected with its end facing away from the vehicle to the crossmember in a respective end section thereof, and with its end facing the vehicle is connectable to a structural component of the vehicle, e.g., a longitudinal member. The crossmember has a corrugated structure in the area where a crashbox is connected. A tow sleeve is integrated into the bumper crossmember in the connection area of the crashbox. The tow sleeve is held in a vertex structure of the corrugated structure in a form-fitting manner in the z and y directions, the vertex area of this vertex structure facing away from the crashbox, with the lateral surface of the tow sleeve on the flanks facing one another and forming the vertex structure.

Bumper cross beam for a motor vehicle

A bumper crossmember comprising a wave structure oriented in the vertical direction (z direction), wherein the wave structure comprises at least three apex structures which extend in the bumper crossmember longitudinal direction and are adjacent in the vertical direction. This crossmember comprises a first length section that follows its longitudinal extent, at least one second length section that follows its longitudinal extent, and at least one transition section that is arranged respectively between these length sections. In the second length section, the wave structure is inverted with respect to the first length section, in that the opening direction of the apex structures switches in the transition section. In the transition section, there is at least one additional apex-forming structure, the apex of which is offset in the frontal direction (x direction) with respect to a frontal plane (yz-plane) in which at least two apex structures that are adjacent in the longitudinal sections lie.

Bumper cross car beam

A bumper, which comprises a bumper crossmember having an outer shell and having at least one sensor holder arranged therein, and an outer cladding shell. The at least one sensor holder is implemented as an impressed pocket originating from the front-side termination of the outer shell and having an upper wall, a lower wall and a base connecting the two walls. On the side of the outer cladding shell pointing toward the bumper crossmember, in the region of a sensor holder, the outer cladding shell carries at least one sensor engaging in the sensor holder.

Bumper

A bumper cross-member for a vehicle having an outer shell and an inner shell connected to the outer shell and having a cut-out section which comprises at least one cut-out passing through the bumper cross-member in the x-direction. The bumper cross-member is divided in the z-direction thereof into at least three sections, of which a first and a second hollow chamber section are separated by a cut-out section located between them.

Bumper cross-member

A vehicle longitudinal member arrangement having two longitudinal members that are spaced apart from one another in the z direction and are designed to absorb energy in the case of an impact, and having a connection component which connects the longitudinal members to one another. The connection component has its main extension in one plane and has an upper attachment section and a lower attachment section. The connection component is arranged with its main extension plane parallel to the longitudinal extension of the longitudinal members connected by said component. Each of the two attachment sections has two attachment points arranged spaced apart from one another in the longitudinal extension of the longitudinal members, at which points the connection component is connected to the respective longitudinal member, while the section of the connection component located between the attachment points is not connected to the respective longitudinal member. The connection component is designed to be weaker in its section located between the attachment points in the direction of the longitudinal extension of the longitudinal member than the sections bearing the attachment points, for the absorption of impact energy.
