The automobile doorsill structure comprises a doorsill body, a supporting beam and a battery edge covering beam, the doorsill body comprises a door ring assembly and an inner plate assembly, a placement cavity is formed between the door ring assembly and the inner plate assembly, and a plurality of reinforcing plate structures are arranged in the placement cavity at intervals in the X direction of a whole automobile coordinate system; the reinforcing plate structure is connected between the door ring assembly and the inner plate assembly; the supporting beam is arranged in the containing cavity and penetrates through the containing cavity in the X direction of the whole vehicle coordinate system. The battery edge covering beam is arranged on one side of the door plate assembly and connected with at least one reinforcing plate structure through a connecting piece. According to the invention, the arrangement area of the supporting beam penetrates through the placement cavity, so that sufficient energy absorption in a multi-point side column collision process can be ensured, and invasion to a passenger compartment is reduced; the door ring assembly, the inner plate assembly and the reinforcing plate structure are connected with the battery edge covering beam, in the multi-point side column collision process, the integrity of the area, with large stress, of the threshold body can be guaranteed, and it is guaranteed that welding spots are not cracked.
本申请涉及一种汽车门槛结构及车辆,其包括:门槛本体、支撑梁和电池包边梁,门槛本体包括门环组成和内板组成,门环组成与内板组成之间形成有安置空腔,沿整车坐标系X方向,安置空腔内间隔设置有多个加强板结构,加强板结构连接于门环组成和内板组成之间;支撑梁设置于安置空腔内部,且沿整车坐标系X方向贯穿安置空腔;电池包边梁设置于门板组成一侧,且通过连接件至少与其中一个加强板结构连接。本发明中,支撑梁的布置区域贯穿安置空腔,能够保证多点侧柱碰过程中充分吸能,减少对乘员舱的入侵;将门环组成、内板组成和加强板结构与电池包边梁连接起来,在多点侧柱碰的过程中,能够确保门槛本体受力较大的区域的完整性,保证焊点不开裂。
