The invention discloses a reinforcing structure of a vehicle girder, the girder is of a non-closed structure, the reinforcing structure comprises a first connecting part, a second connecting part and a fence part located between the first connecting part and the second connecting part, and the first connecting part and the second connecting part are used for being connected with the bottom and the top of the girder respectively. And the enclosure part, the first connecting part, the second connecting part and the girder jointly form a closed structure. The closed structure not only can improve the connection strength between the battery pack and the reinforcing structure as well as the girder, but also can effectively improve the strength of the girder, so that the girder is prevented from being deformed due to overlarge stress, and the stability of the girder is greatly improved; therefore, the situation that the locking mechanism installed on the girder deviates due to deformation of the girder and consequently battery replacement fails is avoided, and the battery replacement success rate is increased. The closed structure is beneficial to various wiring arrangements, has a protection effect on lines such as penetrating cables, and prevents the lines from interfering with a girder or a battery pack, so that the safety and stability are higher.

    本发明公开了一种车辆大梁的加强结构,大梁为非封闭式结构,加强结构包括第一连接部、第二连接部和位于第一连接部、第二连接部之间的围挡部,第一连接部和第二连接部分别用于与大梁的底部和顶部相连接,围挡部与第一连接部、第二连接部、大梁共同形成封闭式结构。封闭式结构不仅能够提高电池包与加强结构和大梁之间的连接强度,也能够有效提高大梁自身的强度,避免大梁因为受力过大而发生形变,大大提高了大梁的稳定性,进而避免安装在大梁上的锁止机构因为大梁的形变而产生位置偏移以导致换电失败,提高换电成功率。封闭式结构内利于各种走线布置,对穿过的电缆等线路具有防护作用,且避免线路与大梁或电池包发生干涉,安全稳定性更高。
