The invention discloses a guiding and limiting device for a battery pack, the battery pack, a battery pack assembly and an electric vehicle. The guiding and limiting device for the battery pack comprises a shell, an elastic mechanism and a limiting piece, wherein the shell is provided with a containing cavity and a limiting hole; the elastic mechanism and the limiting piece are arranged in the containing cavity, the face, away from the elastic mechanism, of the limiting piece is provided with a protruding part penetrating through and protruding out of the limiting hole, and the elastic mechanism is arranged in the containing cavity in a pressed mode through the limiting piece and the shell. And the limiting piece is in floating connection with the shell through the elastic mechanism. According to the invention, the elastic mechanism is arranged in the shell, so that floating connection between the shell and the elastic piece is realized, stable installation of the battery pack and the battery fixing seat can be ensured, jamming is avoided, the requirement on alignment of the battery pack in the installation process is reduced, and the installation efficiency is improved.

    本发明公开了一种电池包用导向限位装置、电池包、电池包总成及电动汽车。电池包用导向限位装置包括壳体、弹性机构和限位件,壳体具有容纳腔和限位孔;所述弹性机构和限位件设于所述容纳腔内,且所述限位件与所述弹性机构相背离的一面具有穿过并凸出所述限位孔的凸起部,所述弹性机构被所述限位件和所述壳体压设于所述容纳腔内,所述限位件与所述壳体之间通过所述弹性机构浮动连接。本发明中,通过在壳体内设置弹性机构,实现壳体与弹性件之间的浮动连接,既能够保证电池包和电池固定座平稳安装、避免卡死,又降低了安装过程中对电池包进行对位的要求,从而有利于提升安装效率。
