Abstract:
A front-body structure for a vehicle comprising:a front pillar erected at a side of said vehicle for forming a passenger compartment, a side sill connected to a lower end of said front pillar and extending in a rearward direction of said vehicle;a front frame extending longitudinally along said vehicle in a forward direction under said vehicle and along an inside position from a side wall of said vehicle for providing a space for a front wheel and for supporting an engine;a toe board rigidly connected to a rear end of said front frame and diagonally inclined in a rearward direction for resting a foot of a passenger thereon, and a floor panel connected to said toe board for horizontally traversing in a widthwise direction of said vehicle, said floor panel forming a flat bottom floor of the passenger compartment;a center tunnel mounted on a center portion of said floor panel and connected to said toe board;an outer reinforcement panel rigidly secured to an undersurface of said toe board and connected to said rear end of said front frame and to said end of said floor panel;an inner reinforcement panel rigidly secured on a top-surface of said toe board and connected to said rear end of said front frame and to said rear end of said floor panel;a front frame connecting portion formed at a front portion of said outer reinforcement panel so as to cover a lower side of said front frame;a first channel portion with a U-shaped cross-section formed in said outer reinforcement panel from said front frame connecting portion to said side sill so as to extend under said floor panel in a rearward and outwardly radial direction in order to effectively disperse a shock from forward direction without breaking;a second channel portion with said U-shaped cross-section formed in said outer reinforcement panel continuously from said front frame connecting portion straight along a forward direction of said vehicle so as to extend under said floor panel in a rearward and a radial direction;a third channel portion with said U-shaped cross-section formed in said outer reinforcement panel from said front frame connecting portion to said center tunnel so as to extend under said floor panel in a rearward and an inwardly radial direction;a first covering portion formed in said inner reinforcement panel continuously from said rear end of said front frame via said toe board to said side sill so as to extend over said floor panel in said rearward and said outwardly radial directions; anda fourth channel portion with an upright U-shaped cross-section formed in said inner reinforcement panel and extending from said rear end of said front frame to said center tunnel via said toe board so as to extend over said floor panel in said rearward and said inwardly radial directions, said fourth channel portion serving to effectively absorb a shock from any direction upon collision of said vehicle with another object;wherein the rear portion of the front frame is covered through the toe board by a front frame securing portion of the outer reinforcement panel and on one end of the inner reinforcement panel, so that impact force can be smoothly dispersed backwardly.
