Patent number: 9925856Abstract: 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.Type: GrantFiled: July 13, 2016Date of Patent: March 27, 2018Assignee: DR.

Patent number: 9911952Abstract: 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).Type: GrantFiled: June 24, 2014Date of Patent: March 6, 2018Assignee: DR.

Patent number: 9802649Abstract: 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.Type: GrantFiled: July 13, 2016Date of Patent: October 31, 2017Assignee: DR. ING. H.C. F. PORSCHE AKTIENGESELLSCHAFTInventors: Eduard Ewert, Ralf Keller

Patent number: 9804060Abstract: 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.Type: GrantFiled: December 16, 2014Date of Patent: October 31, 2017Assignee: DR. ING. H.C.F. PORSCHE AKTIENGESELLSCHAFTInventors: Ralf Keller, Eduard Ewert

Patent number: 9705117Abstract: 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).Type: GrantFiled: October 7, 2015Date of Patent: July 11, 2017Assignee: Dr. Ing. h.c.
