Abstract

The present invention provides a vehicle body frame structure comprising: a frame body having a closed cross-sectional structure formed by joining a first panel and a second panel having a lower strength than the first panel; a cylindrical reinforcement provided inside the frame main body along the frame main body, and a portion of the cylindrical reinforcement on the second panel side is compared with a portion on the first panel side And the whole is set to be thick-walled.

Description

technical field [0001] The present disclosure relates to a vehicle body frame structure and a method of manufacturing the same. Background technique [0002] Japanese Unexamined Patent Application Publication No. 2003-72589 discloses a column structure including: a front column having a closed cross-sectional structure formed by a column inner panel and a column outer panel; and a tube inserted inside the front column. shaped reinforcements. [0003] In the conventional column structure described above, for example, a structure in which the strength of the column outer member is lower than that of the column inner member is considered by making the plate thickness of the column outer member thinner. In such a structure, it is also required to reduce the weight while ensuring the strength of the entire column. Contents of the invention [0004] In consideration of the above circumstances, the present invention provides a vehicle body frame structure and a method of manufa...
