Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a front body reinforcement structure,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a front body reinforcement structure, and more particularly, to a front body reinforcement structure that increases stiffness on the front side of a vehicle body.

Generally, the front vehicle body of the vehicle is constituted by a skeletal structure which is located forwardly along the longitudinal direction of the vehicle to form an engine room.

A front side member formed to extend along the longitudinal direction of the vehicle is disposed on the left and right sides of the engine room to reinforce the structural rigidity of the front vehicle body and to mount the suspension and the like in addition to the engine and transmission installed in the engine room A subframe is disposed below the front side member to support the front side member.

The front side member has a front end portion mounted with a bumper beam formed to extend along the width direction of the vehicle to improve the front collision performance of the vehicle. The bumper beam is guided through the crash box to the front side member And is connected to the front end portion along the longitudinal direction.

In addition, a wheel is formed in left and right sides in the engine room of the automobile, and a wheel house is provided between the wheel and the vehicle body, in which the strut is supported to elastically support the wheel.

The front side member is connected to the lower side of the wheel house.

The front main body reinforcement structure having such a structure absorbs the impact energy transmitted to the vehicle body during the collision of the vehicle through the front side member and collapses to secure the stability of the passenger.

However, since the front side member does not effectively absorb impact energy due to its low stiffness against bending and twisting at the time of impact, the impact energy is transmitted to the occupant through the vehicle body to increase the injury value of the occupant.

In addition, the front side member can not efficiently disperse the impact energy generated when the vehicle collides with other parts of the vehicle body, and thus, the vehicle body damage is rather weighted.

An embodiment of the present invention is to provide a front body reinforcement structure that can improve the front collision performance of a vehicle by increasing connection rigidity of a wheel house and a rear floor panel constituting a vehicle front structure.

The front vehicle body reinforcement structure according to one or more embodiments of the present invention includes: i) a front side inner member formed along the longitudinal direction of the vehicle and disposed on both sides of the dash panel side and connected to the vehicle body; and ii) A front side outer member joined to the inner side surface of the wheel house along the shape of the wheel house to form a reinforcing surface; and iii) And the other end is joined to one side of the rear floor panel, and iv) one side is joined to the rear of the side outer extension member to reinforce both side tunnels of the rear floor panel of the vehicle body, And a rear lower member joined together along the longitudinal direction.

Further, in the front vehicle body reinforcing structure according to the embodiment of the present invention, one side of the reinforcing surface may be superposedly joined to the outside end of the side seal of the vehicle body and one side of the front filler.

Further, in the front vehicle body reinforcing structure according to the embodiment of the present invention, the reinforcing surface may have a joining end at upper and lower ends so as to be joined to the wheel house, and a plurality of forming portions may be formed in the longitudinal direction.

Further, in the front vehicle body reinforcing structure according to the embodiment of the present invention, the reinforcing surface may be formed with a first joint flange at an inner end thereof so that one side of the reinforcing surface is overlapped with the side seal and the front pillar.

Further, in the front vehicle body reinforcement structure according to the embodiment of the present invention, the side outer extension member is superimposed on the inner side surface of the reinforcing surface, and the other end is joined to the rear floor panel, .

Further, in the front vehicle body reinforcement structure according to the embodiment of the present invention, the side outer extension member may be formed with a third joint flange at one end so as to be superposed on the inner side surface of the side seal.

Further, in the front vehicle body reinforcement structure according to the embodiment of the present invention, the rear lower member is formed such that one side thereof is overlapped with the inner side surface of the side outer extension member and both ends thereof are joined to the rear floor panel. A fourth abutment flange may be formed along the longitudinal direction.

In the embodiment of the present invention, the front side outer member, the side outer extension member and the rear lower member are connected to each other in a superposed manner in the wheel house, the rear floor panel, the side seal and the front filler, The connecting rigidity of the panel is increased and the performance of the front collision response of the vehicle can be improved.
