Abstract: The present disclosure relates to a structure of a vehicle body front side member and relates to a technical field of automobile design and manufacture. A vehicle body front side member structure includes a front side member assembly, an upper side beam assembly, a front side member connection plate assembly, an upper side beam front assembly, a front anti-crash beam energy absorption box assembly, and a front anti-crash beam assembly. According to the front side member structure, it is possible to optimize the transmission route of the crash force and effectively improve the capability of the energy absorption of the front end of the vehicle body to reduce the load to the cabin stringer so as to reduce the invasion amount of the front cabin into the passenger cabin or avoid the front cabin from invading into the passenger cabin in order to improve the safety of the driver.
