Abstract

A vehicle front structure comprises a beam member positioned in front of a sub frame and having a closed-cross section extending in a vehicle width direction and a plate member extending forwardly from the beam member. The plate member comprises a fixation portion fixed to the beam member, a body portion extending forwardly from the fixation portion, and a front end portion positioned at a front end of the body portion and configured to have higher rigidity against a load applied in a longitudinal direction than the body portion. The front end portion of the plate member comprises an upper section located at a higher level than the body portion and a lower section located at a lower level than the body portion. The upper section is positioned on a vehicle forward side of the lower section.

First claim

What is claimed is:

1. A front structure of a vehicle, comprising:
a beam member positioned in front of a sub frame and having a closed-cross section extending in a vehicle width direction; and
a plate member extending forwardly from the beam member,
wherein said plate member comprises a fixation portion fixed to said beam member, a body portion extending forwardly from said fixation portion, and a front end portion positioned at a front end of said body portion and configured to have higher rigidity against a load applied in a longitudinal direction of the vehicle than said body portion,
said front end portion of the plate member comprises an upper section located at a higher level than said body portion and a lower section located at a lower level than said body portion,
said upper section is positioned on a vehicle forward side of said lower section,
said front end portion of the plate member comprises said lower section which protrudes downwardly from the front end of said body portion and said upper section which is positioned at a front end of said lower section,
a rib which connects a front end of said front end portion and said body portion is provided,
said beam member comprises a central portion which is positioned at a central side, in the vehicle width direction, of the beam member and extends in the vehicle width direction and end portions which are respectively positioned on opposite sides, in the vehicle width direction, of said central portion and respectively configured to extend obliquely outwardly-and-rearwardly from opposite ends, in the vehicle width direction, of said central portion in a plan view, and
said rib which is provided at a position, in the vehicle width direction, of said front end portion which corresponds to said central portion of the beam member is configured to extend obliquely outwardly-and-rearwardly in the plan view.

2. The front structure of the vehicle of claim 1 , wherein said front end portion of the plate member is configured to have a forwardly-inclined shape.

3. The front structure of the vehicle of claim 2 , wherein said body portion of the plate member is configured to have a liner shape, and a lower rib which connects said fixation portion and said front end portion is provided at a lower face of the body portion.

4. The front structure of the vehicle of claim 3 , wherein a lower end of said lower rib is located at a higher level than a lower end of said lower section of the front end portion of the plate member.

5. The front structure of the vehicle of claim 4 , wherein an under-cover attachment portion is provided at a base portion of said body portion of the plate member such that the under-cover attachment portion extends downwardly from said base portion of the body portion, and a notch is formed at a base portion of said under-cover attachment portion.

6. A front structure of a vehicle comprising:
a beam member positioned in front of a sub frame and having a closed-cross section extending in a vehicle width direction; and
a plate member extending forwardly from the beam member, wherein
said plate member comprises a fixation portion fixed to said beam member, a body portion extending forwardly from said fixation portion, and a front end portion positioned at a front end of said body portion and configured to have higher rigidity against a load applied in a longitudinal direction of the vehicle than said body portion,
said front end portion of the plate member comprises an upper section located at a higher level than said body portion and a lower section located at a lower level than said body portion,
said upper section is positioned on a vehicle forward side of said lower section, and
said front end portion of the plate member is configured to have a forwardly-inclined shape.

7. The front structure of the vehicle of claim 1 , wherein said body portion of the plate member is configured to have a liner shape, and a lower rib which connects said fixation portion and said front end portion is provided at a lower face of the body portion.

8. The front structure of the vehicle of claim 1 , wherein an under-cover attachment portion is provided at a base portion of said body portion of the plate member such that the under-cover attachment portion extends downwardly from said base portion of the body portion, and a notch is formed at a base portion of said under-cover attachment portion.
