Problems solved by technology

However, in Patent Document 1, the roof reinforcement (tongue piece) is joined to the upper surface of the inner end portion in the vehicle width direction of the roof rail outer member, and the roof side rail is not directly supported from the vehicle width direction inner side (inside the vehicle compartment), in other words, directly The structure is designed to withstand the impact load, so the displacement of the roof side rails inward in the vehicle width direction may not be sufficiently suppressed in the event of a side collision of the vehicle

Embodiment 1

[0039] Below, based on Figure 1 to Figure 9 Example 1 of the present invention will be described.

[0040] The vehicle V according to the first embodiment is an FR (Front engine rear drive) automobile equipped with an engine (not shown) disposed longitudinally on the front side of the vehicle compartment and driven by the rear wheels.

[0041] Hereinafter, in the drawings, the arrow F direction is described as the front in the vehicle body front and rear direction, the arrow L direction as the vehicle width direction left, and the arrow U direction as the vehicle body vertical direction upward. In addition, since this vehicle V has a left-right symmetrical structure, unless otherwise specified, the right-side member and the right-side portion will be mainly described below.

[0042] First, the overall configuration will be described.

[0043] Such as figure 1 As shown, the vehicle V has: a pair of left and right side beams 1 extending front and rear; a floor 2 erected bet...

Abstract

Provided is an upper body structure for a vehicle that can reduce displacement of a roof side rail in the event of a side collision and thereby restrain a pillar from moving into a vehicle cabin. Theupper body structure includes: a pair of left and right roof side rails 10 coupled to respective ends of a roof panel 3 in a vehicle width direction and extending substantially in a vehicle front-reardirection; and a roof reinforcement 30 configured to couple intermediate portions in the vehicle width direction of the pair of roof side rails 10. A vehicle-width-direction inner side end of each roof side rail 10 is substantially formed in a concave-convex shape in side view, a vehicle-width-direction outer side end of the roof reinforcement 30 is substantially formed in a concave-convex shapein side view, and the concave-convex shaped end of each roof side rail 10 and the concave-convex shaped end of the roof reinforcement 30 are disposed so as to intersect with each other in side view.

Description

technical field [0001] The present invention relates to an upper vehicle body structure of a vehicle, comprising a pair of left and right roof side rails and a roof reinforcement at a middle portion in the front-rear direction of the vehicle body connecting the pair of roof side rails in the vehicle width direction. Background technique [0002] Conventionally, there is known an upper body structure comprising: a pair of left and right roof side rails connected to both ends of the roof panel in the vehicle width direction and extending along the front and rear directions of the vehicle body; The midway parts of the roof side rails extend downward in the vertical direction; the roof reinforcement member connects the midway parts of the vehicle body front and rear direction of the pair of roof side rails in the vehicle width direction; and the left and right pair of gussets connect the pair of center pillars. Reinforced with roof reinforcement. [0003] In the upper body stru...
