Abstract
Official abstract text for this publication.
An automotive front side frame including a bent portion having a bent form, in at least a portion, comprises an outer frame including a front outer portion and a rear outer portion disposed further to a rear of a vehicle frame than the front outer portion and formed to have tensile strength higher than tensile strength of the front outer portion; and an inner frame including a front inner portion and a rear inner portion disposed further to the rear of the vehicle frame than the front inner portion and formed to have tensile strength higher than tensile strength of the front inner portion.
First claim
Opening claim text (preview).
The invention claimed is: 1. An automotive front side frame comprising: an outer frame comprising a front outer portion and a rear outer portion located at a rear of a vehicle frame than the front outer portion; an inner frame comprising a front inner portion and a rear inner portion located at a rear of the vehicle frame than the front inner portion; wherein a tensile strength of the rear outer portion is higher than a tensile strength of the front outer portion, wherein a difference between the tensile strength of the rear outer portion and the tensile strength of the front outer portion is 300 MPa to 900 MPa, wherein a tensile strength of the rear inner portion is higher than a tensile strength of the front inner portion, wherein a difference between the tensile strength of the rear inner portion and the tensile strength of the front inner portion is 300 MPa to 900 MPa. 2. The automotive front side frame of claim 1 , wherein the inner frame is molded using a tailor welded blank (TWB) to allow the rear inner portion to be formed using a material having tensile strength higher than tensile strength of the front inner portion. 3. The automotive front side frame of claim 2 , wherein the outer frame is formed by rapidly cooling the rear outer portion faster than the front outer portion to allow the rear outer portion to be heat-treated to have tensile strength higher than tensile strength of the front outer portion. 4. The automotive front side frame of claim 3 , wherein the tensile strength of the rear outer portion and the tensile strength of the rear inner portion are 1100 MPa to 1500 MPa, wherein the tensile strength of the front outer portion and the tensile strength of the front inner portion are 600 MPa to 800 MPa. 5. The automotive front side frame of claim 1 , wherein the front inner portion comprises a first bent portion of the inner frame, wherein the rear inner portion comprises a second bent portion of the inner frame, and wherein the inner frame comprises a joint portion connecting the first bent portion of the inner frame and the second bent portion of the inner fame. 6. The automotive front side frame of claim 5 , wherein the outer frame comprises a transition portion connecting the front outer frame and the rear outer portion, wherein the outer frame comprises a first bent portion of the outer frame between the front outer frame and the transition portion, wherein the outer frame comprises a second bent portion of the outer frame between the transition portion and the rear outer frame. 7. The automotive front side frame of claim 6 , wherein the joint portion does not overlap with the first bent portion of the outer frame and the second bent portion of the outer frame. 8. The automotive front side frame of claim 6 , wherein the transition portion overlaps with the joint portion.
