Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a battery shell supporting box and a battery shell packaging structure. Background Art

[0002] The battery case and the battery cell in the battery are usually packaged separately for storage and transportation. During the processing of the battery, the separately packaged battery case and the battery cell need to be assembled separately.

[0003] In the prior art, there are two main packaging solutions for battery shells. The first solution is to use paper box + blister film + dust-free paper to package the battery shell. The battery shell is supported by a paper box, dust-free paper is sandwiched between two adjacent battery shells, and the outer surface of the paper box and the battery shell is covered with a blister film to achieve the packaging of the battery shell. In the first solution, the paper box is prone to produce paper scraps, and the fine paper scraps are easily attached to the surface of the battery shell. In the subsequent assembly process of the battery shell and the battery cell, the attached paper scraps are prone to cause poor welding, affecting the subsequent battery assembly yield. In order to solve the above problems, the second solution replaces the original paper box with a blister box. Although the blister box will not produce debris such as paper scraps that affect the subsequent battery assembly, the processing and manufacturing of the blister box requires the use of an integrated molding processing method for manufacturing, which requires the customization of the molding mold according to actual needs, which increases the processing cost, and also requires the customization of different molding molds according to the actual processing specification requirements of the blister box, which further increases the processing cost.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0043] In the prior art, there are two main packaging solutions for battery shells. The first solution is to use paper box + blister film + dust-free paper to package the battery shell. The battery shell is supported by a paper box, dust-free paper is sandwiched between two adjacent battery shells, and the outer surface of the paper box and the battery shell is covered with a blister film to achieve the packaging of the battery shell. In the first solution, the paper box is prone to produce paper scraps, and the fine paper scraps are easily attached to the surface of the battery shell. In the subsequent assembly process of the battery shell and the battery cell, the attached paper scraps are prone to cause poor welding, affecting the subsequent battery assembly yield. In order to solve the above problems, the second solution replaces the original paper box with a blister box. Although the blister box will not produce debris such as paper scraps that affect the subsequent battery assembly, the processing and manufacturing of the blister box requires the use of an integrated molding processing method for manufacturing, which requires the customization of the molding mold according to actual needs, which increases the processing cost, and also requires the customization of different molding molds according to the actual processing specification requirements of the blister box, which further increases the processing cost.

[0044] In order to solve the above problems, Figure 1 to Figure 5 As shown, this embodiment provides a battery housing support box. The battery housing support box includes a die-cut piece 100, which is integrally folded and formed by the die-cut piece 100. The die-cut piece 100 is made of plastic material. The die-cut piece 100 includes a folding bottom plate 110 and a folding side plate group connected to the folding bottom plate 110. The folding side plate group includes a plurality of folding side plates, each of which is flippably connected to the folding bottom plate 110. The plurality of folding side plates together form a frame structure. The folding bottom plate 110 is sealed at one end of the frame structure. The accommodating cavity in the frame structure is configured to accommodate the battery housing 2000, and the folding bottom plate 110 is configured to support the battery housing 2000.

[0045] The battery housing support box is designed by splitting the die-cut piece 100 into a folding bottom plate 110 and a folding side plate group including a plurality of folding side plates, and each folding side plate is flip-connected to the folding bottom plate 110, so that the plurality of folding side plates together form a frame structure, and ensure that the folding bottom plate 110 is sealed at one end of the frame structure. The battery housing 2000 is accommodated in the accommodating cavity in the frame structure, and the battery housing 2000 is supported by the folding bottom plate 110, so as to achieve the effect of integrally folding the die-cut piece 100 into the battery housing support box. In addition, the die-cut piece 100 is made of plastic material, so that the battery housing support box after folding will not produce debris and other debris, thereby ensuring the subsequent assembly yield of the battery.

By arranging the folding side panel group into a first folding side panel 120 and a second folding side panel 130 arranged opposite to each other along a first direction and a third folding side panel 140 and a fourth folding side panel 150 arranged opposite to each other along a second direction perpendicular to the first direction, the two ends of the first folding side panel 120 and the second folding side panel 130 are respectively connected and fixed to the two ends of the third folding side panel 140 and the fourth folding side panel 150 to form a rectangular frame structure, so that the die-cut piece 100 is folded to form a battery casing support box with a rectangular structure.

[0048] It should be noted that, in this embodiment, the folding bottom plate 110 is rectangular, and the first folding side panel 120, the second folding side panel 130, the third folding side panel 140 and the fourth folding side panel 150 are respectively arranged on one side of the folding bottom plate 110 of the rectangular structure, and the first folding side panel 120, the second folding side panel 130, the third folding side panel 140 and the fourth folding side panel 150 are respectively folded upward 90° relative to the folding bottom plate 110 and are connected and fixed to each other, so that the die-cut piece 100 is folded to form a battery shell support box.

[0049] To further facilitate the folding and forming of the battery casing support box, a pre-folding line is provided at the connection between the first folding side panel 120 and the folding bottom panel 110; a pre-folding line is provided at the connection between the second folding side panel 130 and the folding bottom panel 110; a pre-folding line is provided at the connection between the third folding side panel 140 and the folding bottom panel 110; and a pre-folding line is provided at the connection between the fourth folding side panel 150 and the folding bottom panel 110.

[0050] Specifically, the first folding side panel 120 includes a first folding enclosure portion 121, a first folding fixing portion 122 and a second folding fixing portion 123, wherein the first folding enclosure portion 121 is connected to the folding bottom plate 110, the first folding enclosure portion 121 can be folded relative to the folding bottom plate 110 and blocked laterally in the first direction, the first folding fixing portion 122 and the second folding fixing portion 123 are respectively arranged at two ends of the first folding enclosure portion 121 along the second direction, the first folding fixing portion 122 and the second folding fixing portion 123 can be folded relative to the first folding enclosure portion 121, any one of the first folding fixing portion 122 and the second folding fixing portion 123 is connected and fixed to the third folding side panel 140, and the other is connected and fixed to the fourth folding side panel 150.

[0051] By designing the first folding side panel 120 to be a first folding enclosure portion 121 and a first folding fixing portion 122 and a second folding fixing portion 123 respectively arranged at both ends of the first folding enclosure portion 121 along the second direction, when folded upward 90° relative to the folding bottom panel 110, the first folding enclosure portion 121 is laterally blocked at one end in the first direction. At this time, the first folding fixing portion 122 and the second folding fixing portion 123 located at both ends of the first folding enclosure portion 121 along the second direction are respectively folded relative to the first folding fixing portion 122 toward the direction close to the third folding side panel 140 and the fourth folding side panel 150, and then connected and fixed to the third folding side panel 140 and the fourth folding side panel 150 that are laterally blocked in the second direction.

[0052] Similarly, in order to facilitate the folding of the first folding fixing portion 122 and the second folding fixing portion 123 relative to the first folding enclosure portion 121, a pre-folding line is provided at the connection between the first folding fixing portion 122 and the first folding enclosure portion 121, and a pre-folding line is provided at the connection between the second folding fixing portion 123 and the first folding enclosure portion 121.

[0053] As an optional solution, a first adhesive region 1221 is provided on the first folding and fixing portion 122, and a second adhesive region 1231 is provided on the second folding and fixing portion 123. Glue is provided on the first adhesive region 1221 and the second adhesive region 1231 respectively. The first adhesive region 1221 abuts against the third folding side panel 140, and the other second adhesive region 1231 abuts against the fourth folding side panel 150. By providing the first adhesive region 1221 on the first folding and fixing portion 122, the first adhesive region 1221 abuts against the third folding side panel 140, thereby achieving adhesive fixation of the first folding and fixing portion 122 and the third folding side panel 140; by providing the second adhesive region 1231 on the second folding and fixing portion 123, the second adhesive region 1231 abuts against the fourth folding side panel 150, thereby achieving adhesive fixation of the second folding and fixing portion 123 and the fourth folding side panel 150, the structure is simple and the fixing effect is good.

[0054] Furthermore, the third folding side panel 140 and the fourth folding side panel 150 are folded before the first folding side panel 120 and the second folding side panel 130, and the first bonding area 1221 and the second bonding area 1231 are respectively arranged on the inner end surface of the first folding fixing portion 122 and the inner end surface of the second folding fixing portion 123, the first bonding area 1221 is bonded and fixed to the outer end surface of the third folding side panel 140, and the second bonding area 1231 is bonded and fixed to the outer end surface of the fourth folding side panel 150. When the first folding side panel 120 needs to be bonded and fixed to the third folding side panel 140 and the fourth folding side panel 150, the third folding side panel 140 and the fourth folding side panel 150 are firstly folded upward 90° relative to the folding bottom panel 110, and then the first folding side panel 120 is folded upward 90° relative to the folding bottom panel 110, and then the first folding fixing portion 122 is folded 90° relative to the first folding enclosure portion 121 toward the outer end surface of the third folding side panel 140, so that the first folding fixing portion 122 is located at the outer end surface of the third folding side panel 140. The first bonding area 1221 on the inner end surface of the part 122 is bonded and fixed to the outer end surface of the third folding side panel 140, and the second folding fixing part 123 is folded 90° relative to the first folding enclosure part 121 toward the outer end surface of the fourth folding side panel 150, so that the second bonding area 1231 located on the inner end surface of the second folding fixing part 123 is bonded and fixed to the outer end surface of the fourth folding side panel 150, thereby completing the bonding and fixing of the first folding side panel 120 to the third folding side panel 140 and the fourth folding side panel 150.

[0055] In other embodiments, the third folding side panel 140 and the fourth folding side panel 150 can also be folded after the first folding side panel 120 and the second folding side panel 130, and the first bonding area 1221 and the second bonding area 1231 are respectively arranged on the outer end surface of the first folding fixing portion 122 and the outer end surface of the second folding fixing portion 123, and any one of the first bonding area 1221 and the second bonding area 1231 is bonded and fixed to the inner end surface of the third folding side panel 140, and the other is bonded and fixed to the inner end surface of the fourth folding side panel 150.

[0056] Specifically, if the third folding side panel 140 and the fourth folding side panel 150 are folded after the first folding side panel 120 and the second folding side panel 130, when the first folding side panel 120 needs to be bonded and fixed to the third folding side panel 140 and the fourth folding side panel 150, the first folding side panel 120 is first folded upward 90° relative to the folding bottom panel 110, and then the first folding fixing portion 122 and the second folding fixing portion 123 are respectively folded relative to the first folding enclosure portion 121 in a direction close to the first folding enclosure portion 121, so that the third folding side panel 140 and the fourth folding side panel 150 are bonded and fixed. The fourth folding side panel 150 provides a folding space, and then the third folding side panel 140 and the fourth folding side panel 150 are folded upward 90° relative to the folding bottom panel 110, and the first bonding area 1221 located on the outer end surface of the first folding fixing portion 122 is bonded and fixed to the inner end surface of the third folding side panel 140, and the second bonding area 1231 located on the outer end surface of the second folding fixing portion 123 is bonded and fixed to the inner end surface of the fourth folding side panel 150, thereby realizing the bonding and fixing of the first folding side panel 120 to the third folding side panel 140 and the fourth folding side panel 150.

[0057] As an optional solution, the coverage area of ​​the first bonding area 1221 is smaller than the outer end surface area or the inner end surface area of ​​the first folding fixing portion 122, and the coverage area of ​​the second bonding area 1231 is smaller than the outer end surface area or the inner end surface area of ​​the second folding fixing portion 123. This is to reduce the quality of the glue used on the first bonding area 1221 and the second bonding area 1231, thereby reducing the production cost. In other embodiments, in order to ensure the bonding quality of the frame structure, the first bonding area 1221 can also cover the outer end surface or the inner end surface of the first folding fixing portion 122, and the second bonding area 1231 can cover the outer end surface or the inner end surface of the second folding fixing portion 123, which is not specifically limited in this embodiment.

[0058] In addition, in the present embodiment, the second folding side panel 130 includes a second folding enclosure portion 131 and a third folding fixing portion 132 and a fourth folding fixing portion 133 respectively disposed at two ends of the second folding enclosure portion 131 along the second direction, and a third bonding area 1321 is disposed on the third folding fixing portion 132, and a fourth bonding area 1331 is disposed on the fourth folding fixing portion 133. The folding and bonding steps of the second folding side panel 130 with the third folding side panel 140 and the fourth folding side panel 150 are the same as the folding and bonding steps of the first folding side panel 120 with the third folding side panel 140 and the fourth folding side panel 150, and will not be described in detail here to ensure the brevity of the text.

[0059] Furthermore, in this embodiment, if Figure 5As shown, the first folding fixing portion 122, the second folding fixing portion 123, the third folding fixing portion 132 and the fourth folding fixing portion 133 have the same length, the third folding side panel 140 and the fourth folding side panel 150 have the same length, and the length of the first folding fixing portion 122 is equal to half the length of the third folding side panel 140. By limiting the lengths of the first folding fixing portion 122, the second folding fixing portion 123, the third folding fixing portion 132 and the fourth folding fixing portion 133 to be the same, and limiting the lengths of the third folding side panel 140 and the fourth folding side panel 150 to be the same, when the first folding fixing portion 122, the second folding fixing portion 123, the third folding fixing portion 132 and the fourth folding fixing portion 133 are adhesively fixed to the third folding side panel 140 and the fourth folding side panel 150, the first folding fixing portion 122 and the third folding fixing portion 132 jointly cover the outer end surface of the third folding side panel 140, and the second folding fixing portion 123 and the fourth folding fixing portion 133 jointly cover the outer end surface of the fourth folding side panel 150, not only can the structural strength of the battery shell support box be ensured, but also the aesthetics of the battery shell support box can be improved.

[0060] It should be noted that in other embodiments, under the premise that the lengths of the first folding fixing portion 122, the second folding fixing portion 123, the third folding fixing portion 132 and the fourth folding fixing portion 133 are the same, and the lengths of the third folding side panel 140 and the fourth folding side panel 150 are the same, the length of the first folding fixing portion 122 can also be made less than half of the length of the third folding side panel 140, and this embodiment does not make any specific limitation.

[0061] In an optional embodiment, the die-cut piece 100 is a flat plate structure, and the thickness of the die-cut piece 100 is not less than 5 mm. By limiting the thickness of the die-cut piece 100 to be not less than 5 mm, the structural strength of the folded battery housing support box can be ensured, and the battery housing support box can be prevented from being damaged during the storage support process.

[0062] In addition, in this embodiment, when the die-cut piece 100 is folded into a battery housing support box, the height of the battery housing support box is 20 mm, the length of the battery housing support box is 120 mm, and the width of the battery housing support box is 120 mm. In other embodiments, the length, width, and height of the folded battery housing support box can be adjusted arbitrarily according to the specific specifications and storage requirements of the actual battery housing 2000, and this embodiment does not make specific limitations.
