Problems solved by technology

[0009] Even if it is formed without breaking, it is difficult to ensure sufficient rigidity and strength because the thickness of the upper end becomes thinner in proportion to the increase in elongation.
[0010] In this way, as the elongation of the base material increases, fracture or rigidity and strength decrease, so in Patent Document 1, it is not possible to extend the outer end portion of the second inclined portion toward the outer side of the vehicle. Combined with rear wheel housing
As a result, it is impossible to form a closed cross-section with reinforcement members, and the rigidity and strength of the rear of the vehicle body are insufficient.
Therefore, it is necessary to implement further reinforcement by using additional reinforcement components, etc., but this will lead to an increase in the weight of the vehicle body

Embodiment Construction

[0040] Embodiments of the present invention will be specifically described with reference to the drawings. In the description, the same reference numerals are attached to the same elements, and repeated descriptions are omitted. In addition, "front and rear" indicated by arrows in each figure indicates the vehicle front and rear direction, "up and down" indicates the vehicle up and down direction, and "left and right" indicates the left and right direction (vehicle width direction) viewed from the driver's seat.

[0041] Such as figure 1As shown, the vehicle V to which the vehicle body rear structure according to the embodiment of the present invention is applied is a so-called through-type automobile in which the compartment CR and the trunk LR can communicate.

[0042] The vehicle V mainly includes: rear floor 3; a pair of left and right side frames 4; a middle floor beam 5; a pair of left and right rear wheel housings 6; a pair of left and right side wall panels 7; a shelf...

Abstract

A vehicle body rear structure provided with: side wall panels (7) that are respectively provided to the right and left sides of a vehicle body; a parcel shelf (8) that extends along the vehicle width direction and connects the left and right side wall panels (7); and shelf gussets (1) that extend along the up-and-down direction, that have a vehicle outside end part that is joined to a vehicle inside side surface of the respective side wall panel (7), and that have an upper end that is joined to the parcel shelf (8). Each shelf gusset (1) is structured so as to be partitioned into a first gusset (11) and a second gusset (12) that is arranged behind the first gusset (11). A first closed cross-section part (C1) that extends in the up-and-down direction is formed by the first gusset (11) and the second gusset (12).

Description

technical field [0001] The present invention relates to the rear structure of a vehicle body. Background technique [0002] Patent Document 1 discloses a vehicle body rear structure in which a center floor cross member and left and right ends of an upper back member arranged at a distance from each other up and down are respectively connected by a pair of reinforcement members, and the reinforcement member The outer end of the vehicle is combined with the rear wheel housing. [0003] The reinforcing member is formed in a U-shaped cross section, and the U-shaped cross section is composed of a first inclined portion having a predetermined width in the vehicle width direction, a second inclined portion formed parallel to the first inclined portion at a distance rearward, and the second inclined portion. The first inclined portion and the second inclined portion are constituted by a curved portion connecting the vehicle inner side end portions. In addition, the upper portion o...
