Abstract

A vehicle front structure is provided. The vehicle front structure includes a front bumper beam having a plurality of brackets that extend in the downward direction of a vehicle and coupling components that protrude forward from ends of the respective brackets. A stiffener is horizontally disposed on the coupling components and vertical pins vertically pass through the stiffener from the coupling components.

First claim

What is claimed is:

1. A vehicle front structure, comprising:
a front bumper beam including a plurality of brackets that extend in the downward direction of a vehicle;
coupling components that protrude forward from ends of the respective brackets;
a stiffener disposed horizontally on the coupling components; and
vertical pins that vertically pass through the stiffener from the coupling components,
wherein the coupling components are formed in a band type that surrounds the stiffener and are removably coupled to the brackets, and
wherein the vertical pins include first vertical pins that pass through a first side of each of the first coupling components, then sequentially pass through the stiffener and a second side of each of the first coupling components, and protrude to the exterior.

2. The vehicle front structure according to claim 1 , wherein the first vertical pins are formed in the shape of a bolt and first nuts are coupled with the ends of the first vertical pins that protrude to the exterior after passing through the first coupling components.

3. The vehicle front structure according to claim 1 , wherein:
the coupling components include second coupling components formed integrally with the brackets and bent in a forward direction from the ends of the brackets, and
the vertical pins include second vertical pins fixed to the second coupling components and extending in an upward direction.

4. The vehicle front structure according to claim 3 , wherein second nuts are coupled with the ends of the second vertical pins that protrude to the exterior after passing through the stiffener, and a fixing plate is disposed between the stiffener and the second nut.

5. The vehicle front structure according to claim 1 , wherein the stiffener includes a reinforced fiber material.

6. The vehicle front structure according to claim 1 , wherein the stiffener is formed in a hollow pipe shape.

7. The vehicle front structure according to claim 6 , wherein the cross-section of the stiffener vertical to the length direction is divided into a front portion and a rear portion based on the vehicle and the front portion has a shape having a curvature.

8. The vehicle front structure according to claim 7 , wherein the thickness of the front portion is greater than the thickness of the rear portion.

9. The vehicle front structure according to claim 1 , wherein the stiffener is attached proximate to the brackets and the coupling components.
