The invention discloses an electric vehicle battery pack with ejector rod guiding and an electric vehicle comprising the electric vehicle battery pack, the electric vehicle battery pack comprises at least two containing boxes for containing battery modules and an ejector rod mechanism, the containing boxes are arranged in a spaced mode, and every two adjacent containing boxes are connected through a gap connecting structure to form a gap; the gap connection structure comprises a cover plate; the ejector rod mechanism is arranged in the gap and comprises a vertically-arranged ejector rod, a mounting base and a guide part, the ejector rod can extend to move in the vertical direction, the mounting base is located below the cover plate and connected with at least one containing box on the two sides of the gap, and the guide part is arranged at the position, close to the cover plate, of the mounting base; the cover plate is provided with a jacking hole for the ejector rod to penetrate through, and the guide piece is located between the hole wall of the jacking hole and the ejector rod. The alignment precision is high, the unlocking efficiency is high, contact or abrasion between the ejector rod and the jacking hole is reduced, and the service life of the battery pack is prolonged. The number of the containing boxes is designed according to the space size for containing the battery pack, and standardization is achieved.

    本发明公开了一种具有顶杆导向的电动车辆用电池包及包含其的电动车辆,电动车辆用电池包包括至少两个用于容纳电池模组的容纳箱和顶杆机构,容纳箱间隔设置,两个相邻容纳箱通过间隙连接结构连接并形成间隙,间隙连接结构包括盖板;顶杆机构设置于间隙内,顶杆机构包括竖向设置的顶杆、安装座及导向件,顶杆可延伸竖直方向运动,安装座位于盖板的下方且与所处间隙两侧的至少一个容纳箱连接,导向件设置于安装座靠近盖板的位置处,盖板上开设有供顶杆穿过的顶起孔,导向件位于顶起孔的孔壁与顶杆之间。对准精度较高且解锁效率高,减少顶杆与顶起孔之间发生碰触或磨损,延长电池包寿命。根据容纳电池包的空间尺寸设计容纳箱数量,实现标准化。
