Problems solved by technology

[0024] In a known manner, in roll-formed profiles, which are to absorb energy in the transverse direction, it is difficult to realize transverse load paths, such as ribs, without material doubling in the longitudinal direction, which in turn leads to undesired gaps corrosion

Embodiment Construction

[0054] exist figure 1 A battery box 10 for accommodating battery cells 15 for a motor vehicle is shown in . In the present exemplary embodiment, the structural frame 1 is formed from two structural components 2 joined to one another at the end faces, wherein each structural component 2 has at least one partially hollow profile section 3 that is substantially L-shaped in cross section. . Of course, other profile shapes also fall within the protection scope of the present invention.

[0055] The battery box 10 is usually arranged below the passenger compartment between the front and rear axles of a motor vehicle with an electric drive. The battery cells 15 are used to store electrical energy to drive the vehicle electrically.

[0056] The profile section 3 has a fastening section 11 for screwing the structural component 1 or the battery box 10 to the motor vehicle body by means of fastening means 12 . In particular, the horizontal region 8 of the L-shaped profile section 3 c...

Abstract

The invention relates to a battery box for a motor vehicle for receiving battery cells, having a structural frame with at least two structural components joined to one another at the end face. Each structural component has at least one profile segment that is partially hollow and has a substantially L-shaped cross-section. A reinforcement element for absorbing collision energy in the event of a collision is arranged within at least one of the profile segments. The reinforcement element is a moulded part having a plurality of open cells, which are arranged adjacent to one another and with theirlongitudinal extent substantially parallel to one another. When the battery box is mounted in the motor vehicle, the open cells are oriented with their longitudinal extent substantially parallel to the transverse direction of the vehicle.

Description

technical field [0001] The invention relates to a battery case with reinforcing elements according to the preamble of claim 1 . Background technique [0002] Known electric vehicles have a unit serving as an electrical energy store, referred to below as a battery. In a modular construction, these units are usually divided into individual cells, referred to below as battery cells. For example, such battery cells can be formed from rechargeable secondary cells, commonly referred to as batteries. The individual cells of the electrical energy store are electrically connected to each other to form a so-called battery with a predetermined operating voltage and energy capacity. [0003] For mass production, a battery case is provided to accommodate the individual battery cells. Each individual battery cell is mechanically connected to the battery box in order to prevent it from slipping during operation. In particular, the battery box is intended to be installed in a motor vehi...
