Referring to fig. 1 to 8, a vehicle side member structure has: the longitudinal beam outer plate 1 and the longitudinal beam inner plate 2 are connected to form a longitudinal beam body with a hollow cavity; the triangular boss 11 is arranged on the first end of the girder outer plate 1, and the cross section width of the girder body at the position of the triangular boss 11 is larger than the cross section width near the middle part of the girder body. And by utilizing the structural space at the front end of the longitudinal beam, the design characteristics of a triangle plate are added at the front end of the outer plate 1 of the longitudinal beam, and the triangle plate and the inner plate 2 of the longitudinal beam are lapped to form a variable section. The energy absorption during front-end proving impact has obvious lifting effect. Through the triangle muscle characteristic design of new structure front end, the structure absorbs more front end transmission's energy under the characteristic of variable cross section. The cross-sectional characteristics of the structure vary from 105mm to 80mm for the largest area, increasing the absorption of front end energy by the variable cross-section. The rear compatible design of the stiffener 13 and the bending feature enables the functional definition of bending and support, as shown in fig. 8. In the structure of the girder outer panel 1, the total length of the front end triangular boss 11 in the characteristic X direction is 180mm.

The rear part is compatible with the design of the reinforcing ribs 13 and the bending characteristics, so that the function definition of bending and supporting is realized.
The stringer outer panel 1 and the stringer inner panel 2 are welded. In the structure of the inner plate and the outer plate of the longitudinal beam, the two structures are fixed through welding spots to form a stable inner plate and outer plate system of the longitudinal beam.
The both ends of longeron inner panel 2 bottom are equipped with respectively lower sub vehicle frame front mounting hole 23 and lower sub vehicle frame rear mounting hole 22, and the sub vehicle frame is installed on lower sub vehicle frame front mounting hole 23 and lower sub vehicle frame rear mounting hole 22. Two auxiliary frame mounting hole sites with R=12 are arranged at the bottom of the outer longitudinal beam plate 1Z direction, and the front end and the middle fixing point of the front auxiliary frame are respectively fixed.
Two engine suspension mounting holes 21 are formed in the upper portion of the longitudinal beam inner plate 2, and the engine suspension is mounted on the engine suspension mounting holes 21. In longeron inner panel 2 structure, design has R=8mm's mounting hole, through bolted connection mode and engine suspension fixed connection, forms more firm support.
A transition supporting plate 3 is further arranged at the first end of the longitudinal beam outer plate 1, and the transition supporting plate 3 is connected with the front protection cross beam.
The design function definition of the longitudinal beam structure of the vehicle is aimed at, under the aim of ensuring the use requirement of welding, installing and bearing other structures of the longitudinal beam body, the profile of the front end is increased, and the number of design parts is reduced in a longitudinal beam inner plate and outer plate structure system of the vehicle. Better energy absorption is achieved by providing a variable cross-section design approach.
