Main technical content: This technology adopts a triple structure of an outer frame, a middle frame, and an inner frame. The outer frame has strong structural rigidity. Through the open diagonal on the middle frame, it absorbs energy in the first layer. The structures such as folded edges on the inner frame and straight edges absorb energy in the second layer. And the supporting rods with different materials at the center position form a rigid structure at the center position. Thus, the aluminum alloy profiles not only have the rigid support of the outer frame and the supporting rods, but also have the energy-absorbing buffer structure of the middle frame and the inner frame, which has great bending resistance and provides good safety strength.
