Abstract

A front lower body structure of a vehicle having improved rigidity includes a front side rear lower member connected to a side member inside from a front side member disposed on one side of a fender, a center floor side upper member, and a reinforcing bracket; a center floor side upper member disposed in a longitudinal direction of the vehicle and extending from an upper surface of the dash panel to the center floor panel; the reinforcing bracket connects the front side rear lower member with the central floor side upper member.

Description

technical field [0001] The present invention relates to a front underbody structure of a vehicle having improved stiffness. Background technique [0002] Such as figure 1 and figure 2 As shown, a vehicle equipped with an internal combustion engine distributes the load from the front side member 112 of the fender 111 towards the center floor panel 114 to the center floor side member 116 and the side member inner 117 to transmit the load to the rear side thereof (see figure 1 arrow shown in ). The load input to the front side member 112 is distributed to the center floor side member 116 and the side member inner 117 and transmitted to the rear of the vehicle, thereby ensuring sufficient rigidity against a collision. In addition, a vehicle mounted with an internal combustion engine is formed with a center tunnel 118 so that the center floor panel 114 has an exhaust pipe or the like mounted on a middle portion thereof, thereby also serving to improve rigidity.
