The invention belongs to the technical field of automobile structure optimization design, and provides an A column lower joint structure, an automobile body structure and an automobile, the A column lower joint structure comprises a doorsill beam and an A column, and the doorsill beam extends into an A column lower joint. By means of the A-column lower connector structure, the load borne by tires during collision can be transmitted to the threshold beam, the situation that the A-column lower connector deforms greatly, consequently, the space of a member cabin deforms greatly is avoided, and the situation that in order to solve the problem, the thickness of materials in other places is increased everywhere, and the cost is increased is avoided.

    本发明属于汽车结构优化设计技术领域,提供一种A柱下接头结构及汽车车身结构和汽车,包括门槛梁及A柱,门槛梁延伸到A柱下接头内部。通过本发明的A柱下接头结构,可以将碰撞时轮胎受到的载荷传递到门槛梁,避免A柱下接头发生巨大变形,从而导致成员舱空间变形很大,避免为了解决该问题,其他地方料厚到处增加,增加成本。
