The invention discloses a limiting part, a limiting device, a battery pack, a battery pack assembly and an electric vehicle. The limiting device comprises a shell and a limiting piece. The shell is provided with a containing cavity and a limiting hole, and the limiting hole is located in the mounting surface of the shell; the limiting piece is arranged in the containing cavity, the first end of the limiting piece stretches out of the limiting hole and is provided with a limiting face, and the installation surface and/or the limiting face are/is provided with a containing groove which is concave towards the containing cavity and used for storing lubricating media. According to the invention, the mounting surface and/or the limiting surface are/is provided with the accommodating groove, the accommodating groove is used for storing the lubricating medium, and after the battery pack is mounted on the battery fixing seat, the limiting device and the battery fixing seat are automatically lubricated through the lubricating medium, so that a good use state can be kept for a long time; and the phenomena that the limiting device and the battery fixing seat are rusted and are fixed together due to rusting, so that the battery pack is difficult to disassemble and assemble are avoided.

    本发明公开了一种限位件、限位装置、电池包、电池包总成、电动汽车。限位装置包括壳体和限位件。壳体具有容纳腔和限位孔,所述限位孔位于所述壳体的安装表面上;限位件设于所述容纳腔中,且所述限位件的第一端伸出所述限位孔并具有限位面,所述安装表面和/或所述限位面设置有朝向所述容纳腔凹陷的用于存储润滑介质的容纳槽。本发明中,安装面和/或限位面上设置有容纳槽,容纳槽用于存储润滑介质,电池包安装在电池固定座上之后,限位装置和电池固定座之间通过润滑介质自动润滑,从而能够长期保持良好的使用状态,避免了限位装置和电池固定座生锈以及两者因生锈而固定在一起,使得电池包不易拆装的现象。
