Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings. Only this statement, the utility model discloses the upper and lower, left and right, preceding, back, inside and outside etc. position words that appear or will appear in the text only use the utility model discloses an attached drawing is the benchmark, and it is not right the utility model discloses a concrete restriction.

Referring to fig. 1, the utility model provides a packing box for a laminated battery string, which comprises a battery string box 1 and a string box packing box 2, wherein the battery string box 1 is arranged in the string box packing box 2;

the battery string box 1 comprises a box body 11 and an accommodating cavity 12 for placing the laminated battery string, a groove 13 is formed in the top surface of the box body 11, a protrusion 14 is formed in the bottom of the box body 11, and the protrusions 14 of two adjacent battery string boxes 1 are clamped with the groove 13;

referring to fig. 2, a cutting groove 15 is formed at an inner corner of the battery string box 1 so that an outer corner of the battery string is not in contact with the battery string box 1.

Specifically, a plurality of the battery string boxes 1 are stacked and then placed in the string box packing case 2. For preventing the extrusion, the collision of dislocation slip between the battery cluster box 1 to the shingled battery cluster be equipped with on the box body 11 recess 13 and arch 14 to make adjacent two battery cluster box 1 joint improves the stability between the battery cluster box 1. Since the battery string is mostly made of single crystal silicon, four corners of the battery string are weak portions of the battery string, which are easily damaged by an external force. To solve this problem, the inner corners of the battery string box 1 are provided with cutting grooves 15, and the cutting grooves 15 correspond to the four corners of the battery string, so that the four corners of the battery string are not in contact with the battery string box 1. When the battery string box 1 is extruded by a certain external force, the battery string box 1 deforms, and when the deformation of the battery string box 1 is smaller than the distance between the battery string box 1 and the battery string, the damage of the battery string can be avoided.

In the embodiment, the battery string box 1 mainly comprises two sizes, one is a small box, the length, width and height of the small box are 1200 x 220 x (100-200), and the small box is mainly used for containing a laminated battery string with the length of about 1000 mm; one is a big box, the length, width and height of which are 2020 x 220 x (100-200), and the big box is mainly used for containing a shingled cell string with the length of about 2000 mm.

In order to ensure the clamping stability of the two battery string boxes 1, reduce the thickness of the bulge 14 as much as possible and improve the loading capacity, the depth of the groove 13 and the height of the bulge 14 are 10-15 mm. Within this height range, two of the cases 11 can be stacked smoothly without slipping.

In order to improve the shock resistance and the shock absorption performance of the battery string box 1, the battery string box 1 is made of EVA (ethylene vinyl acetate) or EPP (ethylene propylene rubber). The EVA (ethylene-vinyl acetate copolymer) material has better flexibility and elasticity, and can effectively protect the battery string from external impact. The EPP (expanded polypropylene) material not only has better flexibility and elasticity, but also is an environment-friendly material, can be recycled and reused, can be naturally degraded, and cannot cause white pollution.

A plurality of battery strings 3 are arranged in the battery string box 1, and in order to prevent the battery strings 3 from being worn, sulfur-free paper 4 is arranged between every two adjacent battery strings 3.

Referring to fig. 3, in order to prevent collision impact or contact wear between two battery string boxes 1, a first buffer layer 5 is disposed between two adjacent battery string boxes 1. Further, in order to reduce the impact of external force on the battery string box 1 in the string box packing box 2. In the present embodiment, the first buffer layer 5 is made of pearl wool, but is not limited thereto.

It should be noted that, in order to reduce the transportation damage of the battery string box 1 in the string box packaging box 2, the inner surface of the string box packaging box 2 is provided with a second buffer layer (not visible in the drawings), and the second buffer layer is made of pearl wool, but not limited thereto. In addition, the interior of the string box packaging box 2 is provided with a buffer partition (not shown in the attached drawings). A plurality of battery cluster string box 1 piles up and forms 1 group of battery cluster string box place 1 group of multiunit battery cluster string box in the string box packing box 2, every group between 1 group of battery cluster string box, set up between battery cluster string box 1 and the string box packing box 2 the buffering cuts off, can play the cushioning effect.

Referring to fig. 4, a tray 6 is provided at the lower part of the string box packing case 2. Tray 6 sets up two parallel slots 61, slot 61 and fork truck looks adaptation, the fork truck transport of being convenient for string box packing box 2, simultaneously tray 6 also can make string box packing box 2 dampproofing.

Referring to fig. 5, it should be noted that the existing arrangement of the battery string boxes 1 is not beneficial to recycling, in order to reduce the recycling volume as much as possible and increase the number of the battery string boxes 1 in unit volume, the box body 11 includes a bottom plate 111 and side plates 112, and a notch 113 is formed at the joint of the two adjacent side plates 112, so that the two battery string boxes 1 can be reversely clamped. Specifically, at least two notches 113 are formed in one battery string box 1, and the two notches 113 are arranged diagonally, so that the two battery string boxes 1 can be reversely buckled, that is, one battery string box 1 is reversely buckled on the other battery string box 1 placed in the forward direction, and the recovery efficiency is improved.

To sum up, the utility model provides a stack tile battery cluster packing box, including battery cluster string box 1 and cluster box packing box 2. The top of the box body 11 of the battery string box 1 is provided with a groove 13, and the bottom of the box body is provided with a bulge 14, so that the two box bodies 11 can be clamped and connected without sliding. The inner corners of the box body 11 are provided with cutting grooves 15, so that the outer corners of the battery strings 3 are not in contact with the battery string box 1, the relatively weak outer corners are protected from being extruded and collided, and damage to the laminated battery strings 3 in the transportation process is reduced.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
