[0002] Turnover boxes, as a carrier of logistics, have been widely used for a long time.

[0003] The energy storage battery industry has developed rapidly in recent years. The core component of energy storage batteries, the battery cells, require special containers (or turnover boxes) for transportation. Such containers usually include a container body and an inner liner. The container body includes a bottom wall and surrounding side walls. The inner liner is provided with a positioning groove to position the battery cells. In order to protect the battery cells, a protective pad needs to be provided on the surface of the positioning groove that contacts the battery cells. In the existing structure, a protective pad is mostly attached to the inner liner, which is troublesome to produce and assemble, and the protective pad is easy to fall off. How to design the inner liner and the protective pad on it is one of the key points in the design of the battery cell carrier container. Summary of the invention

[0004] The purpose of the present invention is to provide an off-site transport container for square shell battery cells, which is improved from the perspective of the installation method of the protective cushion, so as to enhance the efficiency of production and assembly and the firmness of the protective cushion.

[0005] To achieve the above object, the technical solution adopted by the present invention is: a square shell battery cell off-site transport container, including a container body and an inner liner, the container body includes a bottom wall and surrounding side walls, the inner liner includes a plurality of positioning strips, these positioning strips are arranged parallel to the top surface of the bottom wall, and at least one side of each positioning strip is provided with a battery cell slot for inserting a battery cell;

[0006] In addition, the positioning strip includes a positioning strip body, a protective pad and a positioning strip top cover; a protective pad groove is provided on the top surface of the positioning strip body, and a plurality of notches are opened on each protective pad groove at the groove wall corresponding to the battery cell slot; the protective pad is embedded in the protective pad groove, and a protrusion is provided at a position corresponding to each notch, and the protrusion protrudes into the battery cell slot through the corresponding notch to serve as an active part on the groove wall of the battery cell slot that contacts the battery cell; the positioning strip top cover is placed on the protective pad groove to fix the protective pad.

[0007] In the above scheme, the positioning strips include two first positioning strips and at least one second positioning strip, the two first positioning strips are arranged at the side walls of the opposite sides of the container body, and the second positioning strip is arranged in the middle of the container body; the battery cell slot is arranged on the side edge of the first positioning strip toward the middle; the battery cell slot is provided on both sides of the second positioning strip.

[0008] Due to the adoption of the above technical solution, the present invention has the following advantages:

[0009] The present invention uses a plurality of parallel positioning strips to form the inner lining of the positioning battery cell, and each positioning strip is designed to be composed of a positioning strip body, a protective pad and a positioning strip top cover. The protective pad is a full-length pad structure that matches the shape of the positioning strip, which is easy to assemble and replace, and is more firmly fixed and has a long service life.
