[0022] As shown in the attached Figure 1 - attached Figure 3As shown in the figure, the utility model relates to a battery pack structure for a new energy powered ship, which includes a plurality of single packs 1.

For the deficiencies in the prior art, the above structure proposes an improved technical solution. When the structure is set, the whole battery pack includes a plurality of single packs 1. Each single pack 1 respectively includes an upper cover 2 and a lower cover 3. The upper cover 2 and the lower cover 3 are buckled and connected, and the battery is located in the single pack cavity formed by the upper cover 2 and the lower cover 3.

The upper cover positioning U-shaped grooves 4 and the lower cover positioning U-shaped grooves 5 are arranged in parallel. A screw fixing sleeve 6 is respectively arranged on the side surface of the upper cover 2 of each single pack 1. In this way, when a plurality of single packs 1 are arranged in a stacked manner up and down, each lower cover positioning U-shaped groove 5 of the lower cover 3 of the upper single pack 1 of two adjacent single packs 1 up and down can be clamped in a corresponding upper cover positioning U-shaped groove 4 of the upper cover 2 of the lower single pack 1.

In the above structure, when a plurality of single packs 1 are arranged in a stacked manner up and down, the upper single pack and the lower single pack are not directly attached, but are clamped through the lower cover positioning U-shaped groove 5 and the upper cover positioning U-shaped groove 4. The clamping realizes buffering on the one hand and limit on the other hand, and the multi-dimensional inertial impact force received by the battery pack can be evenly dispersed.
[0024] When multiple single packages 1 are arranged in a stacked manner up and down, each screw 7 sequentially passes through the screw fixing sleeves 6 of multiple upper covers 2 and is connected to the screw holes on the battery substrate 8. In the above structure, the lowermost single package is arranged on the battery substrate, and multiple single packages are connected through multiple screws, realizing the upper and lower, left and right, and front and back limiting of multiple single packages and being reliably fixed on the battery substrate with reliable connection.

In the above structure, when adjacent single packages 1 are stacked on top of each other, the corresponding positioning U-shaped grooves are clamped and connected, reliably realizing the limiting.
[0026] The multiple upper cover positioning U-shaped grooves 4 of the upper cover 2 extend from the front part of the upper surface of the upper cover 2 to the rear part, and the adjacent upper cover positioning U-shaped grooves 4 are arranged at intervals. The multiple lower cover positioning U-shaped grooves 5 of the lower cover 3 extend from the front part of the lower surface of the lower cover 3 to the rear part, and the adjacent lower cover positioning U-shaped grooves 5 are arranged at intervals.

The upper cover 2 and the lower cover 3 are snap-connected. The battery is located in the single pack cavity formed by the upper cover 2 and the lower cover 3. When the battery pack is formed, adjacent single packs are arranged stacked up and down. In order to solve the problems in the prior art, when setting up the structures of the upper cover 2 and the lower cover 3, multiple upper cover positioning U-shaped grooves 4 are integrally formed on the upper part of the upper cover 2, and multiple lower cover positioning U-shaped grooves 5 are integrally formed on the lower part of the lower cover 3. The upper cover positioning U-shaped grooves 4 and the lower cover positioning U-shaped grooves 5 are arranged in parallel.
