Detailed Description
The structure of the lower leg protection beam assembly of the present invention will be further described with reference to specific embodiments to help those skilled in the art to more fully, accurately and deeply understand the technical solution of the present invention.
Example 1
As shown in fig. 1 to 6, the lower leg protection beam assembly structure of the present embodiment includes a lower leg protection beam 10 and wheel house boundary beam outer plates 50 located at both sides of the rear end of the lower leg protection beam, and a front connection plate 20, a secondary energy absorption box 30, and a rear connection plate 40 are disposed between the lower leg protection beam 10 and the wheel house boundary beam outer plates 50. The wheel house side beam outer plates 50 may be symmetrically disposed at both sides of the rear end of the lower leg shield beam 10. The front connecting plate 20 is arranged at the front end of the auxiliary energy absorption box 30, the rear connecting plate 40 is arranged at the rear end of the auxiliary energy absorption box 30, the auxiliary energy absorption box 30 is fixedly welded with the front connecting plate 20 and the rear connecting plate 40, and the front connecting plate 20 is fixedly welded with the shank protection beam through bolts or carbon dioxide; the rear connecting plate 40 is fixedly connected with the wheel casing boundary beam outer plate 50 through bolts or carbon dioxide welding.
As shown in fig. 7, the shank protection beam assembly structure of the present embodiment is added with an auxiliary energy-absorbing box structure, and the wheel cover side beam outer plate structure effectively extends to the lower end of the shank protection beam, and the auxiliary energy-absorbing box is effectively connected with the shank protection beam and the wheel cover side beam outer plate through bolts or carbon dioxide welding, so that a force transmission path is added to the whole vehicle, and collision energy is effectively dispersed. The structure effectively improves three indexes of MPBD collision OLC, SD and breakdown in 2021-CNCAP.
It is obvious to those skilled in the art that the specific embodiments are only exemplary descriptions of the present invention, and it is obvious that the specific implementation of the present invention is not limited by the above-mentioned manner, and various insubstantial modifications made by the method concept and technical scheme of the present invention are within the protection scope of the present invention.
