Wherein the two frame rails 1 are arranged symmetrically with respect to the central longitudinal axis of the frame 100.
As can be seen from the perspective of fig. 1, each frame member 1 is an integrally formed bending type member, and the structure thereof is optimized by the bending design to reduce the dead weight.
The frame member 1 includes a straight beam portion 11 extending in the longitudinal direction of the frame 100 and a bent portion 12 bent and extended from the front end of the straight beam portion 11. And then the straight beam parts 11 at the rear ends of the two frame girders 1 are spaced in parallel, the transverse distance between the two straight beam parts 11 is kept unchanged, the two bending parts 12 at the front ends are oppositely bent and closed, and the transverse distance between the two bending parts 12 has a tendency of gradually reducing in the front direction.
