In addition, the shell of the invention is of an integrated structure. On the same casing of face guard installation, all use same casing as the benchmark when the position of different face guards is adjusted, the mutual position of adjustment back face guard is unique, and then guarantees that the clearance between face guard and the automobile body is stable, and then guarantees good outward appearance effect.

The multi-face cover mounting structure provided by the invention has the advantages that a single special-shaped lampshade is designed into a plurality of face covers which are spliced, and the problem that the single special-shaped lampshade is difficult to machine and form is solved. Compared with the multi-mask splicing process in the prior art, the process can meet the requirement of harsh modeling, does not need to increase the number of shells and installation parts, and saves a lot of cost; secondly, a plurality of masks are arranged on the same shell, so that different masks have the same positioning reference, and the relative positions among the masks are easier to control; moreover, different masks are fixed on the vehicle body through the same shell, and the masks are the same as the positioning and mounting systems between the vehicle bodies, so that the gap surface difference between the masks and the vehicle bodies can be more accurately controlled.

The invention adopts the crossed glue groove structure of the shell 1 to ensure that the same shell is provided with a plurality of gluing systems, namely, the gluing process only carries out gluing orderly once, thereby realizing the installation of a multi-surface cover, simplifying the complicated gluing path, further reducing the difficulty of the gluing process and ensuring that the gluing process is easier to control. Furthermore, the harsh mask modeling is split into a plurality of masks which are arranged on the same shell, and compared with a traditional design in which one mask corresponds to one shell, the mask modeling method can meet the modeling requirement and avoid the increase of the cost of the shell. In addition, the invention also adopts the positioning ribs 104 in the glue grooves of the shell 1, so that the positions of different masks can be independently controlled, and the difference of clearance surfaces between the masks and the automobile body can be better controlled.
