The invention belongs to the technical field of automobile structures, and particularly relates to a multifunctional front auxiliary frame with a double-frame structure. The multifunctional front auxiliary frame comprises a front cross beam, a left longitudinal arm, a right longitudinal arm and a turtle-shell-shaped lower shell, wherein the left end and the right end of the front cross beam are connected with the left longitudinal arm and the right longitudinal arm respectively; the right longitudinal arm is provided with a first right control tower, a second right control tower and a third right control tower, and the left longitudinal arm is provided with a first left control tower, a second left control tower and a third left control tower; the front cross beam, a front section of the left longitudinal arm, a front section of the right longitudinal arm and a front part of the lower shell form a first frame structure; the front cross beam, the left longitudinal arm, the right longitudinal arm and a rear part of the lower shell form a second frame structure; and the second right control tower and the right longitudinal arm as well as the second left control tower and the left longitudinal arm respectively form a structure shaped like a Chinese character 'ge'. The front auxiliary frame is stable and compact in structure, is provided with a plurality of mounting points of otherfunctional parts, reduces the number of single parts, increases the functions of a product, and reduces the management and control cost in the production of the product.

    本发明属于汽车结构技术领域,具体涉及一种多功能双框架型结构前副车架。其包括前横梁、左纵臂、右纵臂和“龟壳”型下壳体;所述前横梁的左右两端分别与左纵臂、右纵臂相连接;所述右纵臂设置有第一右塔台、第二右塔台、第三右塔台,所述左纵臂设置有第一左塔台、第二左塔台、第三左塔台;所述前横梁、左纵臂前段、右纵臂前段和下壳体前部组成第一框架结构;所述前横梁、左纵臂、右纵臂和下壳体后部组成第二框架结构;所述第二右塔台与右纵臂、所述第二左塔台与左纵臂分别形成“个”字型结构。该前副车架结构稳定、紧凑,设置有多个其他功能件的安装点,减少了单件数量,增加了产品的功用,降低了产品生产中的管控成本。
