Problems solved by technology

[0003] However, both the axial load receiving member and the moment receiving member of the front side frame disclosed in Patent Document 1 have a tapered shape with a thin front part and a thick root part, and there is a problem that the production cost of the mold increases when the plastic working is performed.
In addition, the thin front part is easily deformed, and each size is different, so there is a problem that it is difficult to use
In addition, when the axial load receiving member and the moment receiving member are combined, positioning is difficult and workability is poor

Abstract

A vehicle body front structure provided with left and right front side frames (16, 17). The left front side frame (16) has a rectangular closed cross-sectional shape. The front side frame (16) is provided with a rectilinear section (front half frame section) (44) extending rectilinearly from the front end (58) to the center section (43), and also with a moment receiving section (rear half frame section) (45) continuing from the rectilinear section (44) and extending in a curved form toward the inner side in the widthwise direction of the vehicle. A first ridge line section (78) is a portion which forms a corner (78) among the corners (78) of the rectilinear section (45), said corner (78) being located on the inner side in the widthwise direction of the vehicle. A second ridge line section (84) is connected to the first ridge line section (78) at a position inside the moment receiving section (45). A stiffener (65) is connected to the rear end (66) of the front side frame (16).

Description

technical field [0001] The present invention relates to a front body structure in which left and right front side frames extending forward from a floor of a vehicle compartment are curved. Background technique [0002] Some of the front body structures are provided with front side frames that are bent to the left and right of the engine disposed in front of the cabin. The front side frame is composed of an axial load receiving part and a moment receiving part, wherein the axial load receiving part has a linear first ridgeline in the entire length range in the longitudinal direction, and the moment receiving part has a front-rear direction from the first ridgeline. The second ridge line that branches off at the substantially central portion of the front side frame and bends inward in the vehicle width direction as it goes toward the rear of the vehicle suppresses deformation during a collision (for example, refer to Patent Document 1). [0003] However, both the axial load r...
