Title:
VEHICLE REAR STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2017/119472
Kind Code:
A1
Abstract:
[Problem] To achieve weight reduction in a vehicle body structure without compromising collision safety performance in relation to impacts from the rear of the vehicle. [Solution] Provided is a vehicle rear structure 1 equipped with a pair of rear frames 4 disposed extending in the vehicle length direction and a rear floor panel 2 joined to the pair of rear frames 4, wherein the rear floor panel 2 has a recessed portion 3 extending from the rear of the rear floor panel 2 to the front, and the recessed portion 3 is formed from a metal sheet having a tensile strength equal to or more than that of the pair of rear frames 4. This configuration allows collision energy to be absorbed mainly by the rear floor panel 2 when impact load from the rear of the vehicle acts on the recessed portion 3 of the rear floor panel 2. Thus, this reduces the burden placed on the rear frames 4 in regards to absorbing collision energy and thereby allows the rear frames 4 to be made thinner and shorter and the overall vehicle structure to be made lighter.
