The invention provides a pure electric vehicle cabin cross beam structure assembly, which belongs to the technical field of vehicle assembly, most parts in an electric vehicle cabin are fixed by only using three accessories, and compared with a conventional welding cross beam with dozens of parts, the pure electric vehicle cabin cross beam structure assembly is simple in structure and light in weight, and the process complexity is greatly reduced. The cross beam adopts a hollow aluminum casting process, and the left bracket and the right bracket adopt a low-pressure aluminum casting process, so that the bracket has the characteristics of light weight and high structural strength. The strength and modal requirements of a front drive motor and an air conditioner compressor can be met, and meanwhile the torsional rigidity of a body in white can be greatly improved. By means of the cross beam system, the fixing scheme of a plurality of systems and parts of a cabin can be achieved, the number of parts of the whole vehicle is greatly reduced, and the weight of the whole vehicle is reduced. The rear-drive vehicle is not provided with the front drive motor, the front drive motor and the front motor suspension support are not installed, installation of other parts is not affected, and maximum generalization of cabin arrangement can be achieved.

    本发明提供了一种纯电动汽车机舱横梁结构总成,属于汽车装配技术领域,本发明横梁只用三个配件就固定了电动车机舱内大多数零件,与以往十几个零件的焊接横梁相比结构简单、重量轻、极大降低工艺复杂程度。横梁采用空心铸铝工艺,左支架和右支架采用低压铸铝工艺,具有重量轻、结构强度高的特点。可满足前驱动电机、空调压缩机的强度和模态需求,同时可大幅提高白车身扭转刚度。通过此横梁系统,可实现机舱多个系统和零件的固定方案,极大的减少了整车零件的数量、降低整车重量。后驱车型无前驱动电机,则前驱动电机及前电机悬置支架不安装,不影响其他零件安装,可实现机舱布置最大通用化。
