The invention relates to a battery pack shell upper cover plate assembly, a machining method thereof and a vehicle, and the machining method comprises the steps that a cover plate body is machined, and the cover plate body is used for sealing an opening of a battery pack shell and serves as a vehicle body floor; a plurality of cross beams are machined respectively; a plurality of cross beams are fixed to the upper surface of the cover plate body, the cross beams are arranged at intervals in the front-back direction of the vehicle and extend in the left-right direction of the vehicle, and the cross beams are used for being connected with a vehicle body of the vehicle. The upper cover plate assembly and the cover plate body manufactured through the machining method can serve as a part of a battery pack shell to play a sealing role and can also serve as a whole vehicle floor, the integration degree between a battery pack and a vehicle body is improved, the vehicle body floor does not need to be additionally arranged, and the weight of the whole vehicle is reduced. The cross beams can provide mounting points for other parts of the vehicle body and the battery pack, so that the battery pack can be connected to the vehicle body, the rigidity and strength of the cover plate body are improved, and the battery pack in the shell is protected.

    本公开涉及一种电池包壳体上盖板总成及其加工方法和车辆,加工方法包括:加工盖板本体,盖板本体用于封闭电池包壳体的开口,并用作车身地板;分别加工多根横梁;将多根横梁固定在盖板本体的上表面,其中,多根横梁沿车辆的前后方向间隔布置且沿车辆的左右方向延伸,多根横梁分别用于与车辆的车身连接。通过该加工方法制成的上盖板总成,盖板本体既可以作为电池包壳体的一部分,起到密封作用,同时还能够用作整车地板,提高电池包和车身之间的集成度,无需额外设置车身地板,降低整车重量。多根横梁能够为车身的其他零件提供安装点,为电池包提供安装点,使电池包能够连接于车身,增加了盖板本体的刚度和强度,对壳体内的电池包起到保护作用。
