The rear body structure of the vehicle

Abstract

In order to suppress the relative displacement of the rear door lintel and the roof side member and improve the rigidity of the rear of the vehicle body, the rear door lintel (2) extends in the vehicle width direction along the upper edge of the tailgate opening (1) that opens toward the rear of the vehicle at the rear of the vehicle body. A junction C where the outer end in the width direction and the rear end of the roof side rail (6) extending in the vehicle front-rear direction at the vehicle body side is provided with a beam extension (44) extending across the roof side rail (6) and a rear door lintel ( 2) The extended door lintel extension (42) and the integrally formed reinforcing member (40), the rear door lintel outer parts provided in the rear door lintel (2), namely the rear door lintel reinforcement (22) and the hinge reinforcement (23) and the reinforcement member (40) at least between the lintel extension parts (42), several closed sections (2s, 23s) extending in the vehicle width direction in the vehicle front-rear direction are formed adjacent to each other, and between the door lintel extension part (42) and the beam extension part (44) A relative displacement restraining part (45) for restraining the relative displacement of the rear door lintel (2) and the upper side beam (6) is arranged between them.

Description

technical field [0001] The present invention relates to a rear body structure of a vehicle including a roof side rail extending in the vehicle front-rear direction at the side of the vehicle body, and a rear door lintel extending in the vehicle width direction at the rear part of the vehicle body, and facing the rear at the rear part of the vehicle body. A junction where the upper corners of the open tailgate opening meet. Background technique [0002] Vehicles include models such as minivans, vans, and hatchbacks, in which the rear end portion of the rear of the vehicle body has a tailgate opening that opens toward the rear from a rear end portion provided in the rear of the vehicle body. [0003] As a tailgate opening, there is known a structure having a tailgate which is openable and closable, such as a flip-up type tailgate rotatably connected to the upper edge of the tailgate opening on the vehicle body side by a hinge. [0004] Generally, a tailgate is larger than a s...

Problems solved by technology

[0006] However, if the rear lintel is intensively reinforced, the rear lintel and the rear end are joined between the upper side beams at the outer ends in the vehicle width direction of the rear lintel, that is, the junction of the rear lintel and the upper side rail has poor rigidity. are prone to relative displacement, which is worrying
