Title
(EN) REAR VEHICLE BODY STRUCTURE OF VEHICLE
(JA) 車両の後部車体構造
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a rear vehicle body structure of a vehicle allowing efficient energy absorption at the time of a rear collision, improvement of proof stress for the rear collision, and improvement of rear vehicle body rigidity by two structural bodies on one side of a rear frame and a reinforcement.

SOLUTION: This structure is provided with an opening part for communicating the inside and outside of a cabin at a rear part of a vehicle body. A recessed part 6 is formed by recessing a rear part of a floor panel 4 of the vehicle to a lower side. In the floor panel 4, a rear frame 11 extending in a front and rear direction of the vehicle is disposed. A kick-up part 12 having a position corresponding to the recessed part 6 extending to be curved to an upper side is provided in a rear part of the rear frame 11. The reinforcement 13 for reinforcing extending to a rear side of the vehicle in parallel with the kick-up part 12 or substantially parallel with the part 12 is mounted at a lower end of the recessed part 6.

【課題】後突時のエネルギ吸収の効率化が図れ、後突に対する耐力の向上を図ることができると共に、リヤフレームとレインフォースメントとの片側2本の構造部材により後部車体剛性の向上を図ることができる車両の後部車体構造の提供。
【解決手段】車体の後部に車室内外を連通する開口部を備えた車両の後部車体構造であって、車両のフロアパネル4の後方部を下方に凹設して凹設部6が形成され、上記フロアパネル4には車両の前後方向に延びるリヤフレーム11が配設されると共に、上記リヤフレーム11の後部は凹設部に対応した位置が上方に曲がって延びるキックアップ部12を備え、上記凹設部下端にはキックアップ部12と平行または略平行して車両後方に延びる補強用のレインフォースメント13が取付けられたことを特徴とする。
