The invention discloses a front wall lower cross beam structure and a design method thereof, the front wall lower cross beam structure comprises a lower cross beam main body and a steering column fixing seat split from a front wall lower cross beam, and the lower cross beam main body and the steering column fixing seat are welded, fixed and sealed. The front wall lower cross beam structure is split, the split part is used for fixing and sealing the steering column, the front wall structure is simplified, occupation of vehicle body metal plates on cabin space layout is reduced, and the influence of a power assembly on the steering column in the collision process is reduced.

    本发明公开了一种前围下横梁结构及其设计方法,包括下横梁主体以及由前围下横梁拆分出的转向柱固定座,下横梁主体与转向柱固定座焊接固定并进行密封。本发明将前围下横梁结构拆分,拆分部分作为转向柱固定和密封作用,简化前围结构,减少车身钣金对于机舱空间布局的侵占,减少碰撞过程中动力总成对于转向柱的影响。
