  • Patent number: 10960777
    Abstract: An electric vehicle component (1) for an at least partially electrically driven motor vehicle (100) that has a drive device (2) with an electric drive unit (12) and a carrying unit (22) for fastening the drive unit (12) to a vehicle load-bearing structure (101). The electric vehicle component has a battery device (3) for supplying the drive unit (12) with electric energy. A run-on element (4) is arranged on the drive device (2) and is configured for running onto the battery device (3) in a targeted manner with a run-on geometry (14) in the case of an accident-induced movement of the drive unit (12) so that a punctiform and/or inhomogeneous loading situation of the battery device (3) is counteracted.

  • Patent number: 9925856
    Abstract: An arrangement in a motor vehicle includes a subframe. An energy source is arranged in a region of the subframe and components are assigned to the energy source. The energy source and the components are positioned in front of the subframe in a crash direction. The subframe has a window which exceeds the external dimensions of at least one of the energy source or the components and is configured to allow the at least one of the energy source or the components to dip into the window.

  • Patent number: 9911952
    Abstract: A battery module (10) for a motor vehicle has at least one battery cell (12) for producing and storing electrical energy and a rigid battery frame (14) in which the at least one battery cell (12) is accommodated. An absorption element (24) is secured to the battery frame (14) by connection sections (28). The absorption element (24) is spaced apart from the battery frame (14) in such a way that a cavity (26) is formed between the absorption element (24) and the battery frame (14).

  • Patent number: 9802649
    Abstract: A body part of a vehicle includes a structural component and a deformation component. A connecting component is fastened to an end portion of the deformation component. The connecting component has a contact surface configured to come into contact with a mating contact surface of the structural component. A normal spacing is formed between the contact surface and the mating contact surface, and the connecting component is configured to form force-transmitting contact between the contact surface and the mating contact surface in the event of a crash.

  • Patent number: 9804060
    Abstract: A crash barrier for implementing a collision with a vehicle has a front to be moved toward the vehicle when the collision is implemented. The front side has a predetermined width and a predetermined height. The front side further has a selected surface region that takes up at most a 50% part of a width of the front side. A volume region of the crash barrier behind the surface region has a greater level of rigidity than a surrounding region of the crash barrier. Therefore, in the event of an impact against the vehicle, a greater level of rigidity acts in the selected surface region than in a surrounding region.

  • Patent number: 9705117
    Abstract: A battery housing part (10) for a traction battery has opposite first and second vertically aligned housing walls (12, 14) for laterally covering battery cells, a second housing wall (14) from a floor level (28) to a cover level (30) and horizontally from a left side level (32) to a right side level (34). At least one reinforcement profile (18) is connected to the first housing wall (12) and the second housing wall (14) for at least partial dissipation of impact forces in the case of a crash of the motor vehicle. The reinforcement profile (18) is spaced apart both from the floor level (28) and the cover level (30) and from the left side level (32) and the right side level (34).
