Abstract

A front vehicle body reinforcing structure and an assembly method may include a front side member formed to extend along a length direction of a vehicle and respectively disposed at right and left sides along a width direction of the vehicle, a front fender apron member formed to extend along the length direction of the vehicle, disposed at the right and left sides along the width direction of the vehicle outside the front side member, and including a front tip end positioned at the front along the length direction of the vehicle, and a reinforcement member connecting the front tip end of the front fender apron member and the front side member to be reinforced.

First claim

What is claimed is:

1 . A front vehicle body reinforcing structure comprising:
a front side member formed to extend along a length direction of a vehicle and respectively disposed at right and left sides along a width direction of the vehicle; a front fender apron member formed to extend along the length direction of the vehicle, disposed at the right and left sides along the width direction of the vehicle outside the front side member, and including a front tip end positioned at a front along the length direction of the vehicle; and a reinforcement member connecting the front tip end of the front fender apron member and the front side member to be reinforced.

2 . The front vehicle body reinforcing structure of claim 1 , wherein
a first end along the width direction of the vehicle of the reinforcement member is inserted into the front tip end of the front fender apron member to be integrally combined, and a second end of the reinforcement member is inserted inside the front side member at a predetermined portion along the length direction of the front side member to be integrally combined.

3 . The front vehicle body reinforcing structure of claim 1 , wherein, when the reinforcement member is connected to the front side member and the front fender apron member, the reinforcement member has a structure that extends along the width direction of the vehicle.

4 . The front vehicle body reinforcing structure of claim 1 , wherein the reinforcement member includes:
an inner coupling part inserted inside the front side member to be combined; an outer coupling part inserted into the front tip end of the front apron member; and a connection part integrally connecting the inner coupling part and the outer coupling part.

5 . The front vehicle body reinforcing structure of claim 4 , wherein the connection part is inclined and extended from the inner coupling part outside the width direction of the vehicle and upward of a height direction of the vehicle to be combined to the outer coupling part.

6 . The front vehicle body reinforcing structure of claim 4 , wherein the connection part, the inner coupling part, and the outer coupling part are respectively formed of a rectangle block shape.

7 . The front vehicle body reinforcing structure of claim 4 , wherein the front fender apron member includes:
a front fender apron inner member positioned inside in the width direction of the vehicle; and a front fender apron outer member positioned outside in the width direction of the vehicle, and wherein the front fender apron inner member and the front fender apron outer member are combined to each other to form a front opening.

8 . The front vehicle body reinforcing structure of claim 4 , wherein the front side member includes a front side inner member having a cross-section of a “C” shape in additional to a lateral opening opened toward the outside along the width direction of the vehicle, and the inner coupling part is inserted into the lateral opening to be integrally combined with the front side inner member.

9 . The front vehicle body reinforcing structure of claim 1 , wherein the reinforcement member includes:
an inner plate combined with the front side member; an outer plate combined with the front fender apron member; and two connection plates connecting the inner plate and the outer plate.

10 . A method of assembling a front vehicle body reinforcing structure, comprising:
manufacturing a front side compliance member including a front side inner member provided with a lateral opening; manufacturing a front side outer member to be divided into two; manufacturing a front fender compliance apron having a front fender apron member including a front tip end positioned at a front along a length direction of a vehicle; manufacturing a reinforcement member including an inner coupling part positioned inside along the width direction of the vehicle, an outer coupling part positioned outside, and a connection part connecting the inner coupling part and the outer coupling part; inserting the inner coupling part of the reinforcement member to the lateral opening of the front side inner member to be combined to an upper surface and a lower surface along a height direction of the vehicle of the front side inner member and an inner surface along the width direction of the vehicle; combining the front side outer member to the front side inner member to close the lateral opening of the front side inner member; and insert the outer coupling part of the reinforcement member to the front tip end of the front fender apron member.

11 . The method of claim 10 , wherein the connection part is inclined and extended from the inner coupling part outside in the width direction of the vehicle and upward in the height direction of the vehicle to be combined to the outer coupling part.

12 . The method of claim 10 , wherein the connection part, the inner coupling part, and the outer coupling part are respectively formed of a rectangle block shape.

13 . The method of claim 10 , wherein the reinforcement member includes:
an inner plate forming the inner coupling part combined with the front side member; an outer plate forming the outer coupling part combined with the front fender apron member; and two connection plates connecting the inner plate and the outer plate.
