US 6843524 B2Abstract
a front-compartment framework member forming a front compartment of the vehicle; a floor framework member forming a cabin floor of the vehicle; a subframe arranged on the underside of the front compartment of the vehicle so as to span both of the front-compartment framework member and the floor framework member, the subframe being joined to both of the front-compartment framework member and the floor framework member and also having a pair of left-and-right side frames both extending in a fore-and-aft direction of the vehicle and a rear frame arranged on the rear side of the subframe to connect the left-and-right side frames with each other in a width direction of the vehicle, the subframe further includes a pair of forked parts formed on respective rear sides of the left-and-right side frames, the forked parts each having an inside branch part extending toward the rear frame and an outside branch part projecting from the corresponding inside branch part outward in the width direction of the vehicle; and a vehicle unit component supported by the subframe, wherein the subframe is configured so that a collision load, which has been applied on one of the left-and-right side frames in an axial direction, is directed: along a first route, including the one side frame and the inside branch part of the respective forked part, toward on inside of the one side frame in the width direction of the vehicle to transmit the collision load to the other side frame through the rear frame, and along a second route, including the one side frame and the outside branch part of the respective forked part, toward an outside of the one side frame in the width direction of the vehicle to transmit the collision load to the floor framework member; and the floor framework member comprises: a pair of extension side members formed to extend from the respective rear ends of the left-and-right side members to the underface of the cabin floor in the fore-and-aft direction of the vehicle; a pair of side sills arranged on both sides of the cabin floor to extend in the fore-and-aft direction of the vehicle; and a pair of outriggers connecting the front ends of the extension side members with the front ends of the side sills respectively. 2. The front body structure of claim 1, wherein
the front-compartment framework member comprises a pair of left-and-right side members both extending in a fore-and-aft direction of the vehicle; the subframe further includes a pair of forked parts formed on respective rear sides of the left-and-right side frames respectively, the forked parts each having an inside branch part extending toward the rear frame and an outside branch part projecting from the corresponding side frame outward in the width direction of the vehicle; the left-and-right side frames are provided, on front ends thereof, with front mount parts respectively; the outside branch parts of the forked parts are provided with rear mount parts respectively; respective front ends of the left-and-right side frames are joined to the underfaces of the left-and-right side members respectively through the front mount parts; the outside branch parts of the forked parts are joined to the underface of the floor framework member through the rear mount parts; the first route has the inside branch part; and the second route has the outside branch part. 3. The front body structure of claim 1, wherein the rear mount parts of the subframe are joined to the vicinities of the front ends of the side sills respectively.
a front-compartment framework member forming a front compartment of the vehicle; a floor framework member forming a cabin floor of the vehicle; a subframe arranged on the underside of the front compartment of the vehicle so as to span both of the front-compartment framework member and the floor framework member, the subframe being joined to both of the front-compartment framework member and the floor framework member and also having a pair of left-and-right side frames both extending in a fore-and-aft direction of the vehicle and a rear frame arranged on the rear side of the subframe to connect the left-and-right side frames with each other in a width direction of the vehicle; a vehicle unit component supported by the subframe; a first route means established on the rear side of the subframe to direct a collision load, which has been applied on one of the left-and-right side frames in an axial direction, toward an inside of the one side frame in a width direction of the vehicle to transmit the collision load to the other side frame through the rear frame; and a second route means established on the rear side of the subframe to direct the collision load toward an outside of the one side frame in the width direction of the vehicle to transmit the collision load to the floor framework member. Description
a front-compartment framework member forming a front compartment of the vehicle; a floor framework member forming a cabin floor of the vehicle; a subframe arranged on the underside of a front compartment of the vehicle so as to span both of the front-compartment framework member and the floor framework member, the subframe being joined to both of the front-compartment framework member and the floor framework member and also having a pair of left-and-right side frames both extending in a fore-and-aft direction of the vehicle and a rear frame arranged on the rear side of the subframe to connect the left-and-right side frames with each other in a width direction of the vehicle; a vehicle unit component supported by the subframe; a first route established on the rear side of the subframe to direct a collision load, which has been applied on one of the left-and-right side frames in an axial direction, toward an inside of the one side frame in a width direction of the vehicle to transmit the collision load to the other side frame through the rear frame; and a second route established on the rear side of the subframe to direct the collision load toward an outside of the one side frame in the width direction of the vehicle to transmit the collision load to the floor framework member. BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 7 shows the third embodiment of the invention. In this embodiment, the subframe 11 is provided, behind the forked parts 14, with notches 19 each serving as a weakened part between the inside branch part 14 a and the outside branch part 14 b. According to the embodiment, owing to the provision of the notches 19 each positioned at a boundary part between the inside branch part 14 a and the outside branch part 14 b, the collision load transmitted from the front side of one side frame 12 in the axial direction causes the forked part 14 to be deformed as if the above boundary part were torn with the notch 19 as the starting point of tear, whereby the conversion of load in the width direction of the vehicle to the first route A and the second route B can be promoted.
