Therefore, a battery module hoisting tool is needed to solve the hoisting problem between the battery packs in the narrow space, and is prepared for realizing the automatic assembly of the battery module.

Disclosure of Invention

In order to make up for the defects of the prior art, the utility model aims to provide a battery pack hoisting structure, which solves the problem of hoisting and mounting a battery pack and a whole vehicle when the size space of the battery pack is small.

Battery package hoisting structure includes box and lifting hook, the box both sides set up the hoist and mount hole site, the hoist and mount hole site is sunken and forms the protruding chamber that can hold the lifting hook in the box inboard, the lifting hook is embedded in the protruding intracavity behind the hoist and mount hole site. The space waste caused by independently designing the external lifting holes is reduced, and the space compactness is improved when the product is designed and arranged.

Furthermore, the hoisting hole positions are arranged on two corresponding sides of the box body.

Furthermore, a box cover is further arranged on the box body and fixed with the box body through bolts.

Furthermore, the lifting hook comprises a hook end, and the hook end is hooked into the lifting hole and then embedded into the convex cavity.

Further, the lifting hook comprises a hanging end, and the hanging end is of a circular ring structure.

Furthermore, each side of the hoisting hole is at least two.

Furthermore, the convex cavity completely covers the hoisting hole site, and the periphery of the convex cavity is tightly welded with the inner wall of the box body.

Furthermore, the radian of the convex cavity matched with the end of the hook is also provided with an inclined plane.

Compared with the prior art, the utility model has the following advantages:

1. when the box body is hoisted, the lifting hook is embedded, and a convex cavity is arranged in the box body, so that the protection grade of the box body is ensured;

2. the hoisting holes of the box body are distributed on two sides of the box body, so that the balance of the hoisting structure is ensured; when the convex cavity of the hook of the box body is welded, full welding needs to be ensured, and the strength and the waterproof performance of the lifting hole are ensured;

3. the battery pack hook hole sites are designed in an embedded mode, so that space waste caused by the independent design of external hanging holes is reduced, and the space compactness is improved when products are designed and arranged.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is an exploded view of the structure of the present invention.

In the figure: 1-box body, 2-box cover, 21-bolt, 3-lifting hook, 31-hanging hook end, 32-hanging end, 4-lifting hole position, 41-convex cavity and 42-inclined plane.

Detailed Description

The utility model will be further explained with reference to the drawings.

As shown in fig. 1, the battery pack case 1 is a rectangular parallelepiped structure, the case cover 2 is fixed to the case 1 by bolts 21, and holes fixed to the bolts 21 are regularly and comprehensively formed around the case 1 and the case cover 2 to ensure sealing performance and waterproof performance. Two hoisting holes 4 are correspondingly arranged on two sides of the box body 1 respectively, and the hook ends 31 of the four hooks 3 are embedded in the four hoisting holes 4 of the box body 1; the annular hanging end 32 of the hanging hook 3 is used for hanging the box body 1 on the whole vehicle.

It can be understood that the battery pack box body 1 is hoisted to the whole vehicle through the lifting hook 3, and the hook 31 and the hoisting hole position 4 are designed in an embedded mode, so that the space waste caused by independently designing the external hoisting hole is reduced, and the compactness of the space is improved when the product is designed and arranged.

In addition, in order to ensure the stability of the box body 1, at least two corresponding hoisting hole positions 4 are arranged on two sides of the box body 1 respectively.

As shown in fig. 2, a convex cavity 41 is provided on the inner side of the box body 1 relative to the hole site 4, that is, the hole site 4 is recessed and a convex cavity 41 capable of accommodating the hook 3 is formed on the inner side of the box body 1, and the hook 3 is embedded in the convex cavity 41 after being hooked into the hole site 4. The hoisting hole positions 4 are completely covered by the convex cavity 41, the periphery of the convex cavity 41 is tightly welded with the inner wall of the box body 1, and the sealing performance in the box body 1 is ensured. The arc of the protruding cavity 41 relative to the hook end 31 is further provided with an inclined surface 42, so that the hook 3 is more tightly matched with the hoisting hole site 4 and the protruding cavity 41.
