Detailed ways

As shown in Figures 1 and 2, a main box member of an electric vehicle battery box structure, the main box member is composed of a bottom plate 2 and two opposite ends that are integrally connected with the ends on both sides of the bottom plate 2 and are perpendicular to the bottom plate. The stamping part formed by bending the side plate 7, wherein, on the outer surface of the bottom plate 2, a plurality of sliding grooves 21 in a concave structure extending in parallel for matching with the roller slideways on the electric vehicle are provided. In this embodiment, the cross section of the chute is rectangular, and the transition connection between the bottom of the rectangular chute and the side wall of the chute is a circular arc transition, and a protruding structure is arranged between every two adjacent chute 21 The bottom reinforcing rib 22 of the protruding structure forms a step structure with the chute 21 of the recessed structure adjacent to the bottom reinforcing rib 22 of the protruding structure. A plurality of connected reinforcing rib protruding blocks 23 are arranged, and a partition in a concave structure located on the outer surface of the bottom plate is provided between two adjacent reinforcing rib protruding blocks along the extending direction of the chute, and the bottom of the partition It is on the same plane as the groove bottom of the rectangular chute, and in this embodiment, the structure on the inner surface of the bottom plate corresponding to the position of the bottom reinforcing rib on the outer surface of the bottom plate is the same as the protruding structure of the bottom reinforcing rib Corresponding to the concave structure, the concave structure on the inner surface of the bottom plate corresponds to the protruding structure of the bottom reinforcing rib on the outer surface of the bottom plate, which is convenient for stamping design during the stamping process of the bottom plate. On the outer surface of the bent side plate 7 of the main box member, a protruding block 71 protruding from the outer surface of the bent side plate and extending in parallel with the chute on the bottom plate is arranged. There are two protruding blocks arranged in parallel in the direction perpendicular to the bottom plate. As shown in FIG. 1 , mounting structures corresponding to the electrical components in the battery box are provided on the protruding blocks.

The main box body in the above embodiments is processed by stamping technology, and has high overall strength and light weight.

The bottom plate in the above-mentioned embodiment is a stamping part, and the bottom reinforcing ribs in a protruding structure on the outer surface of the bottom plate and the concave structure corresponding to the position on the inner surface of the bottom plate are structures formed at the same time by stamping, just because the bottom plate One is viewed from the outer surface of the base plate and the other is viewed from the inner surface of the base plate only. It is also possible to change the stamping process, so that only the bottom reinforcement ribs are stamped out during stamping, and no corresponding concave structure is left on the inner surface of the bottom plate.

As shown in Figure 3, a battery box structure for an electric vehicle includes a main box member 1 and a front baffle 4 and a rear baffle 3 installed at the front and rear ends of the main box member. The structure of the main box member 1 adopts The structure shown in Figure 1, and the block code 5 is set on the protruding block on the bent side plate 7 of the main box member, so as to provide an operable space for the installation of electrical components, so that the battery module in the battery box more solid. And it can be seen from Figure 2 that, viewed from the outer surface of the bottom plate, the bottom reinforcing rib is in a protruding structure, while the chute is in a concave structure. When viewed from the inner surface of the bottom plate, it corresponds to the position of the concave structure of the chute It is a convex structure, and the position corresponding to the convex structure of the bottom rib is a concave structure. During the connection process between the main box and the front and rear baffles, since the front and rear baffles have gaps corresponding to the protrusions of the main box, the installation of the front and rear baffles is convenient, and the connection strength between the two is also enhanced. The strength of the whole battery box is improved.

As shown in Figure 4, after assembling the box body shown in Figure 3, put the power battery in the battery box 10, and cover the battery box cover, then put the battery box as a whole into the power cabin 11 of the electric vehicle The chute on the bottom plate of the main box body of the battery box 10 corresponds to the roller slideway 112 in the power cabin 11 of the electric vehicle. The weight of the entire battery box reduces the volume occupied by the battery box.
