In the embodiment shown in fig. 1, and as further detailed in connection with fig. 2, 3, 6 and 7, the guide surface 602 is adapted to cooperate with an electric vehicle when the battery pack 2 is moved in the lifting direction, and the guide flange 603 is adapted to cooperate with an electric vehicle when the battery pack 2 is moved in the locking direction. As shown in fig. 2, the guide surface 602 cooperates with the electric vehicle to guide the movement of the battery pack 2 when the battery pack 2 is lifted, facilitating the movement of the battery pack 2 into place. The guide folded edge 603 is matched with an electric vehicle when the battery pack 2 moves in the horizontal direction, and the guide folded edge 603 is formed by folding the guide rib 601, so that the guide folded edge 603 has good bending strength, and the shape stability of the guide rib 601 at the position of the guide folded edge 603 is easy to maintain.
In the embodiment shown in fig. 1, in conjunction with the drawing, more specifically, the guide surface 602 is disposed on a side of the guide rib 601 away from the center of the battery pack 2, and the guide flange 603 is disposed on a side of the guide rib 601 near the center of the battery pack 2. As shown in the figure, the guiding surface 602 is located at the outer side, so that the top of the guiding rib 601 faces outwards to form a chamfer, the outward corner angle is reduced, and the possibility of damage caused by collision of external objects is reduced.
In the embodiment shown in fig. 1, in conjunction with the drawing, more specifically, the bottom of the guide flange 603 abuts against the top surface of the battery pack 2, and the bottom portion of the guide rib 601 extends to the side surface of the battery pack 2. As shown, the ground of the guide rib 601 extends to the side of the battery pack 2, and the guide rib 601 can be fixed at the side of the battery pack 2, so as to reduce the occupation of the top space of the battery pack 2 by the fixing structure of the guide rib 601 on the battery pack 2. The guide flange 603 can be abutted against the top of the battery pack 2, so that the supporting effect on the guide flange 603 is improved, and the structural stability of the guide flange 603 is maintained.
In the embodiment shown in fig. 1, in conjunction with fig. 3, it is further specified that the guide does not protrude beyond the sides of the battery pack 2. This reduces the increase in the lateral profile of the battery pack 2 due to the protruding guide portion from the side of the battery pack 2, so that the battery pack 2 can be moved and stored.
