DETAILED DESCRIPTION

[0028] In order to more clearly illustrate the embodiments of the utility model and the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work. In addition, the design orientation only represents the relative position relationship between the components, not the absolute position relationship.

[0029] The utility model embodiment provides a battery core material box, please refer to Figure 1-Figure 9, mainly including a material frame 1, a pad 2, and a grid 3. A grid 3 is arranged in each of the two long side walls of the material frame 1. The grid 3 includes a plurality of partitions 31 distributed at equal intervals. The gap between two adjacent partitions 31 is used to insert the battery cell. A plurality of grid grooves 21 are evenly spaced on the two long sides of the pad 2. The spacing between two adjacent grid grooves 21 is the same as the width of the gap, and the width of the grid groove 21 is the same as the thickness of the partition 31. The two long sides of the pad 2 correspond to the grids 3 on both sides of the material frame 1 and are inserted into the bottom of the material frame 1, so that the battery cell inserted in the gap is located above the pad 2.

[0030] In the present application, the material frame 1 is a rectangular frame structure, specifically including a top frame 11 and a bottom frame 12. The top frame 11 is not provided with a cover plate, and the bottom frame 12 is provided with a bottom plate. The material frame 1 includes a long side and a short side. The top frame 11 and the bottom frame 12 at the short side are provided with a connecting structure, and the long side is not provided with a connecting structure. Figure 2 as shown in .

[0031] The material frame 1 includes two grid plates 3, which are respectively arranged in two opposite long side walls. The two grid plates 3 are supported and limited by a pad 2. When matched with the frame structure of the material frame 1, the structure of the two grid plates 3 is stable and does not shake.

[0032] In a specific embodiment, the grid plate 3 includes a plurality of partitions 31 distributed at equal intervals. The partitions 31 are vertically arranged and arranged in parallel. There is a gap between two adjacent partitions 31. The gap is used for inserting the battery cells. The width of the gap is substantially consistent with the thickness of the battery cells. The partitions 31 have a considerable length and can stably support the posture of the battery cells so that the battery cells in each gap maintain a relative spacing and can avoid wrong grasping, empty grasping, multiple grasping, etc. when being grasped.

[0033] In the present application, the grid plate 3 further includes a bottom plate 32 and a top plate 33 , the upper ends of the plurality of partitions 31 are fixedly connected to the top plate 33 , the lower ends of the plurality of partitions 31 are fixedly connected to the bottom plate 32 , and the plurality of partitions 31 are arranged in parallel.

[0034] It is feasible to place two grid plates 3 in the material frame 1 first, insert the pad 2 between the two grid plates 3, press the pad 2 downward to match the structure of the material frame 1 to preliminarily position the grid plates 3, and then fix the grid plates 3 on the bottom frame 12.

[0035] Specifically, the bottom of the material frame 1 includes a bottom frame 12 and a frame plate disposed in the bottom frame 12. The frame plate is sunken to form a bottom groove, and the bottom plate 32 is fixed in the bottom groove. Figure 3 An inner fixing hole 34 is provided on the inner side of the bottom plate 32, and a horizontal fixing plate 35 is provided on the outer end of the bottom plate 32. The fixing plate 35 has an outer fixing hole. The bottom plate 32 is fixed to the bottom frame 12 through the inner fixing hole 34 and the outer fixing hole.

[0036] It can be understood that the inner fixing hole 34 is opened directly based on the bottom plate 32, and the opening position can be close to the inner edge and away from the position of the partition 31; the fixing plate 35 is arranged on the outer side of the bottom plate 32, below the horizontal section, and the outer fixing hole is opened on the fixing plate 35.

[0037] In a feasible embodiment, the rear end of the partition 31 gradually increases from top to bottom, and the width of the grid groove 21 is the same as the thickness of the lower end of the partition 31, which facilitates the insertion and positioning of the pad 2, and the support and positioning structure of the pad 2 for the grid plates 3 on both sides is stable.

[0038] A plurality of through holes 22 are provided in the middle of the pad 2, which may be elliptical holes; a bottom rib 23 is provided on the back side of the pad 2, and the bottom rib 23 is provided between the plurality of through holes 22 and the plurality of grid grooves 21 on the two long side walls, such as Figure 6 As shown in , the supporting effect on the battery cell is stabilized.

[0039] In the embodiment of the present application, a plurality of partitions 31 are evenly spaced to form a gap, and the partitions 31 are in direct contact with the side walls of the battery cell, so that a certain friction force is present when inserting or removing the battery cell. After the structural dimensions of the partitions 31 are designed, the inserted battery cell should also be limited to avoid shaking of the battery cell and uneven loading.

[0040] In a feasible embodiment, a first page plate 311 and a second page plate 312 are disposed on both sides of the partition 31, the second page plate 312 is located at the rear side of the first page plate 311, and the width of the first page plate 311 is smaller than the width of the second page plate 312; the first page plate 311 stops the long side end wall of the pad 2. On this basis, the battery cell can be abutted against the first page plate 311, and the second page plate 312 can be used to enhance the structural stability.

[0041] Of course, since the width of the first page 311 is smaller than that of the second page 312, when the thickness of the loaded battery cell is slightly thinner and longer, it can abut against the second page 312. Based on this, when there are multiple page structures, the applicable range of battery cell loading is also increased accordingly.

[0042] When the applicable size of a single grid plate 3 is insufficient, grid plates 3 of other spacings can be changed, that is, the spacing between the partitions 31 of the grid plates 3 can be adjusted. Multiple groups of grid plates 3 and matching pads 2 can be provided to facilitate synchronous replacement.

[0043] In the present application, the grid plate 3 and the material frame 1 can be installed in a semi-fixed manner, the bottom of the grid plate 3 can be fixedly connected to the material frame 1, and the upper end can be hung in the material frame 1 or restricted by the material frame 1.

[0044] In a feasible embodiment, the upper end of the partition 31 is bent outward and extends horizontally to form a horizontal section, and the top plate 33 is located at the outer end surface of the horizontal section. The upper part of the material frame 1 includes a top frame 11, and the horizontal section and the top plate 33 are hung on the top frame 11.

[0045] In order to facilitate the insertion of the backing plate 2, the structure of the partition 31 can be optimized, and the place where the horizontal section and the partition 31 body are connected is designed to be an arc structure, such as Figure 7 as shown in .

[0046] At this time, the top frame 11 is exposed. On this basis, please refer to Figure 2 The upper surface of the top frame 11 is provided with a first scale 111, a second scale 112, and a third scale 113. The first scale 111 is arranged on the long side of the top frame 11, and the second scale 112 and the third scale 113 are arranged at both ends of the short side of the top frame 11, respectively corresponding to the partitions 31 on both sides of the material frame 1.

[0047] In the present application, the scale is set to facilitate the identification of the applicable size of the material frame 1, so that the staff can load the appropriate battery cells into the corresponding battery cell box, and effectively avoid possible grasping difficulties, grasping errors, etc. in the subsequent operation process.

[0048] In another possible embodiment, see Figure 8 , Fig. 9 A top frame 11 and a counterweight frame 4 are provided on the upper part of the material frame 1. The counterweight frame 4 is stacked and fixed on the top frame 11. The horizontal section is higher than the top frame 11 and not higher than the counterweight frame 4, so that the top plate 33 abuts against the inner wall of the counterweight frame 4.

[0049] At this time, the top frame 11 itself is blocked, and the scale can be set on the counterweight frame 4, and the setting position can remain unchanged.

[0050] It is understandable that multiple counterweight frames 4 can be stacked to increase the height of the material frame 1 to match the grid plate 3, enhance the restraining effect on the battery cells, and make the upper ends of the battery cells more stable and neatly arranged for easy grasping. When multiple counterweight frames 4 are stacked, the counterweight frame 4 with scales can be placed at the top.

[0051] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device comprising the elements.

[0052] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementation methods, and the specific embodiments of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
