The invention discloses an automobile front cross beam structure. The structure comprises a cabin, a front coaming cross beam, a front vertical beam rear plate, a lower column A, an inner plate reinforcing plate, a front vertical beam, a connecting plate, an upper short beam, and a tower base. The front vertical beam is stressed to transmit a collision force to the cabin through the inner plate reinforcing plate and the front vertical beam rear plate; and/or the front vertical beam is stressed to transmit the collision force to the cabin through the front coaming cross beam; and/or the front vertical beam is stressed to transmit the collision force to the tower base through the connecting plate and the upper short beam; and/or the front vertical beam is stressed to transmit the collision force to the lower column A through the connecting plate and the upper short beam. According to the automobile front cross beam structure, dead weight is reduced on the basis that collision performanceis met; and a problem of structural instability such as structural tearing and the like is effectively avoided.
本发明公开了一种汽车前部横梁结构,包括:机舱;前围板横梁;前纵梁后板;下A柱;内板加强板;前纵梁;连接板;上短梁;塔座;前纵梁受力将碰撞力通过内板加强板、前纵梁后板传递至机舱;和/或前纵梁受力将碰撞力通过前围板横梁传递至机舱;和/或前纵梁受力将碰撞力通过连接板、上短梁传递至塔座;和/或前纵梁受力将碰撞力通过连接板、上短梁传递至下A柱。实施本发明的汽车前部横梁结构,在满足碰撞性能的基础上,减轻自重;有效避免结构撕裂等结构不稳定的问题。
