The bottom of the beam arm shrouding is provided with beam arm shrouding sill strip faying surface, the beam arm shrouding sill strip faying surface with The junction of beam arm shrouding outer surface has beam arm shrouding reinforcing prop, and there is the inner surface of beam arm shrouding beam arm shrouding inner surface to add Strengthening tendons.

Beam arm die casting before described new-energy automobile, it is characterised in that：Described beam arm main body and the material of beam arm shrouding Matter is respectively aluminium alloy, is molded using vacuum die casting process.

In the utility model, beam arm main body and beam arm shrouding individually carry out manufacture production, in later stage assembling process It is combined use.Because preceding beam arm die casting is main stress members in whole lower body front portion, and its quality Weight and volume are big, process more difficulty using common die casting mode, to ensure the quality of production of this part, improve its mechanical property Can, the utility model uses advanced evacuated die-casting process technology.Whole beam arm body outer surface and inner surface structure shape all compare Complexity, with reinforcement of different shapes and section bar overlap edge.The shape of beam arm shrouding is according to the knot that side is bonded with beam arm main body Configuration shape is designed, while with while be brought into close contact, in order to the realization of Joining Technology.To reach light-weighted purpose, this part is adopted With aluminum alloy materials, beam arm main body uses engraved structure, is then combined with beam arm shrouding, forms the sky of a relative closure Between structure, there is light weight, the advantages of intensity is high, while corrosion resistance is strong.

The beneficial effects of the utility model：

The utility model changes orthodox car lower body structure, can made according to the needs of new-energy automobile body structure The lower body intensity of vehicle body increases so that the connection of lower body front frame and middle carriage is relatively reliable, for whole Positioning action is played in the assembling of vehicle body.
