The invention discloses a battery pack mounting point sealing structure. The battery pack mounting point sealing structure comprises an upper shell, a lower shell and a middle cross beam arranged between the upper shell and the lower shell, and further comprises a first sleeve and a second sleeve, the first sleeve is arranged on the side, close to the upper shell, of the middle cross beam, and theupper end of the first sleeve is in lap joint with the upper shell; and the second sleeve is coaxially sleeved in the first sleeve, the outer wall of the lower end of the second sleeve is connected with the lower shell in a sealed mode, the outer side of the upper portion of the second sleeve is connected with the upper shell through a sealing gasket, the upper end of the second sleeve extends out of the upper shell and is in threaded connection with a pressing nut, and the sealing gasket is compressed by screwing the pressing nut to seal the second sleeve and the upper shell. On the premiseof meeting the waterproof and dustproof requirements of the battery pack, the arrangement is more flexible, the maintainability of the battery pack is improved, and the maintenance cost of the batterypack is reduced. The invention also discloses a battery pack and a vehicle with the battery pack mounting point sealing structure.

    本发明公开了一种电池包安装点密封结构,包括上壳体、下壳体和设于上壳体和下壳体之间的中部横梁,还包括第一套筒和第二套筒,所述第一套筒设于中部横梁靠近上壳体的一侧,上端与上壳体搭接;所述第二套筒同轴套接于第一套筒的内部,下端外壁与下壳体密封连接,上部外侧通过密封垫与上壳体接合,上端伸出于上壳体且螺纹连接有压紧螺母,通过旋紧压紧螺母压缩密封垫以密封第二套筒和上壳体。其在满足电池包防水防尘要求的前提下,布置更加灵活,提高电池包可维修性,降低电池包维修成本。本发明还公开了具有上述电池包安装点密封结构的电池包和车辆。
