The invention relates to the field of battery packs of electric automobiles, and provides a limiting device for a battery pack, the battery pack, a battery pack assembly and an electric automobile, the electric automobile comprises the battery pack assembly, the battery pack assembly comprises the battery pack and a battery pack support, the battery pack comprises the limiting device, and the limiting device comprises a shell and a first limiting part. The shell comprises an outer shell and an inner shell, the inner shell is movably covered with the outer shell, the outer shell and the inner shell are movably connected through a connecting piece to form a containing cavity, and the first limiting part extends and protrudes towards the outer shell from the end of the inner shell and is used for limiting movement of the outer shell relative to the inner shell. The relative movement between the outer shell and the inner shell is limited through the first limiting part, so that abnormal sound generated by the relative movement of the inner shell and the outer shell is reduced or avoided, damage to the inner shell and the outer shell is relieved or avoided, impact transmitted to the battery pack from the limiting device is relieved, and the stability of the battery pack is improved.

    本发明涉及电动汽车的电池包领域,提供一种用于电池包的限位装置、电池包、电池包总成、电动汽车,该电动汽车包括该电池包总成,该电池包总成包括该电池包和电池包支架,该电池包包括该限位装置,该限位装置包括壳体和第一限位部,壳体包括外壳和内壳,外壳活动地盖合于内壳上,外壳和内壳通过连接件活动连接以形成容纳腔,第一限位部自内壳的端部朝向外壳延伸凸起,用于限制外壳相对内壳的运动。通过第一限位部限制外壳和内壳之间的相对运动,以减小或避免内壳和外壳相对运动产生的异响,减轻或避免内壳和外壳的损坏,并缓解自限位装置传递至电池包的冲击,提高电池包的平稳性。
