The anti-collision frame comprises a front anti-collision cross beam 1, a left inclined support 2, a right inclined support 3, a left support 4, a right support 5, a middle reinforcing rib 6, a first connecting block 7, a second connecting block 8, a plug cover 9, a threaded screw sleeve 10 and a frame transition piece 11.
Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
As shown in figure 1, the heavy-duty automobile front lower protection mainly comprises a front anti-collision crossbeam 1, a left support 4 and a right support 5 which are respectively fixedly connected with the left end and the right end of the inner side surface of the front anti-collision crossbeam 1, a left inclined support 2 and a right inclined support 3, wherein the left inclined support 2 is fixedly connected between the left end of the front anti-collision crossbeam 1 and the left support 4, the right inclined support is fixedly connected between the right end of the front anti-collision crossbeam 1 and the right support 5, and a middle reinforcing rib 6 is fixedly connected between the inner side surfaces of the left support 4 and the right support 5 and the front anti-collision crossbeam 1, wherein the front anti-collision crossbeam 1 is integrally of an arc-shaped structure in the length direction, the cross section of the front anti-collision crossbeam 1 is of a hollow irregular structure with uneven thickness and reinforcing ribs, as shown in figure 3, the wall thickness of the joints of the front anti-collision crossbeam 1, the left support, the cross sections of the left support 4, the right support 5, the left inclined support 2 and the right inclined support 3 are all regular uniform-thickness shell structures with hollow reinforcing ribs inside, as shown in fig. 4.
