The embodiment of the invention discloses a vehicle body forecabin structure. The vehicle body forecabin structure comprises a ceiling front cross beam. The two A columns are arranged at intervals in the width direction of the vehicle; the invention discloses a dash panel cross beam assembly. Two ends of the ceiling front cross beam are respectively connected with the two A columns, two ends of the dash panel cross beam assembly are respectively connected with the two A columns, and the ceiling front cross beam, the two A columns and the dash panel cross beam form a first annular structure, the dash panel cross beam assembly is provided with a dash panel cross cavity extending in the width direction of the vehicle. One technical effect of the embodiment of the invention is that the double-ring structure is formed, so that the downward pressure from the direction of a car roof can be improved; for front collision force, the force bearing effect can also be improved; for offset collision, when the roof side rail is stressed, the roof side rail can be prevented from inclining towards the interior of the vehicle under the offset collision force, and two collided vehicles can deviate from each other at the collision position.

    本申请实施例公开了一种车身前舱结构。所述车身前舱结构包括顶棚前横梁;A柱,两个所述A柱沿车辆的宽度方向间隔设置;前围板横梁总成。所述顶棚前横梁的两端分别与两个所述A柱连接,所述前围板横梁总成的两端分别与两个所述A柱连接,所述顶棚前横梁、两个所述A柱以及所述前围板横梁形成第一环状结构,其中,所述前围板横梁总成设置有沿车辆宽度方向延伸的前围板横空腔。本申请实施例的一个技术效果在于,通过形成双环结构,对于来自车顶方向的下压力能够提高;对于前碰力,也能够提高承力效果;对于偏置碰,能够在上边梁受力时,防止上边梁受偏碰力向车内倾斜,而且能够让两个碰撞的车在碰撞处相互背离。
