Embodiments of the present invention are described below with reference to the drawings. As shown in fig. 1, 2 and 3, the battery module outer frame includes a frame body 1 and a cover plate 2 that covers the frame body 1 and is fixed to the frame body 1. The frame body 1 includes: the cell comprises a bottom 11, a side 12 and a side 13, wherein the side 12 and the side 13 are oppositely arranged and are vertically connected with the bottom 11, the two sides are mutually separated to form a spacer region 4, and the cell is placed in the spacer region 4. The end of the side portion 12 facing away from the bottom portion 11 is provided with an attachment area 120 and the end of the side portion 12 facing away from the bottom portion 11 is provided with an attachment area 130. The cover plate 2 includes: the top 21, the butt-joint part 22 and the butt-joint part 23 are oppositely arranged and are vertically connected with the top 21, the butt-joint part 22 corresponds to the side part 12 and is fixed on the connecting area 120, and the butt-joint part 23 corresponds to the side part 13 and is fixed on the connecting area 130.

It will be appreciated that the

side portions

12 and 13 may be disposed at angles other than perpendicular to the base 11, as shown in fig. 1, 2 and 3, as well as at angles other than perpendicular to the base 11, such as at angles of 30 °, 40 °, 60 ° or other angles between the

side portions

12 and 13 and the base 11, and at angles other than the same between the

side portions

12 and 13 and the base 11. Likewise, the angles between the butting portion 22 and the butting portion 23 and the top portion 21 may be 30 °, 40 °, 60 ° or other angles, and the angles between the butting portion 22 and the butting portion 23 and the top portion 21 may not be the same angle. The

side portions
