Description

Technical Field

[0001] The utility model relates to the technical field of battery cell storage, in particular to an EPS packaging box for a battery cell. Background Art

[0002] At present, some battery cell manufacturers use EPS packaging boxes for temporary storage or packaging of battery cells when they are put into storage or shipped. Considering that the size of the packaging box is moderate to prevent taking up too much storage space and needs to match the size of the battery cell, there is less space for movement after the battery cell is placed in the battery cell slot of the packaging box. After the packed battery cell is placed in the box, the packaging box cover is very easy to scratch the battery cell, and the closing process is more difficult. In addition, during transportation, the blue film and top patch of the battery cell will easily rub against the packaging box slot, resulting in poor appearance of the top patch being crushed, blue film being scratched, etc., which reduces the customer's user experience. In addition, after the battery cell is placed in the packaging box, it is sealed with a stretch film. When the packaging environment conditions are different from the storage or transportation environment conditions, the water vapor in the air in the packaging box may condense, resulting in water droplets on the surface of the battery cell. The presence of water droplets may accelerate the corrosion of the pole, causing unnecessary scrapping and affecting the quality of the battery cell. Utility Model Content

[0019] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] Example 1

[0021] See also Figure 1-6 A battery cell EPS packaging box comprises a box body 1, wherein the box body 1 comprises a top cover 101, at least one middle cover 102 and a bottom cover 103 which are stacked and installed in sequence from top to bottom, and a single-layer groove 2 is provided at the lower part of the top cover 101, the upper part of the bottom cover 103, and the upper and lower parts of the middle cover 102; when there are more than two middle covers 102, the single-layer groove 2 at the lower part of the top cover 101 and the single-layer groove 2 at the upper part of the middle cover 102, between the single-layer grooves 2 at the upper and lower parts of adjacent middle covers 102, and between the single-layer grooves 2 at the lower part of the middle cover 102 and the single-layer grooves 2 at the upper part of the bottom cover 103 can all be spliced ​​to form a battery cell storage position, and the battery cell storage position is provided with air holes 3.

[0022] The battery cell EPS packaging box of this embodiment includes a top cover, multiple middle covers and a bottom cover that can be stacked and installed on each other. Therefore, multiple layers of battery cell storage positions can be realized. Each layer of battery cell storage positions is isolated from each other and is provided with ventilation holes to facilitate the taking and placing of the battery cells. In addition, air can circulate through the ventilation holes, thereby reducing the temperature difference between the inside and outside and thereby reducing the possibility of condensation water.

[0023] In a specific example, the vent holes 3 of the cell storage positions between the top cover 101 and the middle cover 102 , between adjacent middle covers 102 , and between the middle cover 102 and the bottom cover 103 are staggered with each other.

[0024] In this embodiment, the air holes between each layer of battery cell accommodating slots are staggered to improve air circulation.

[0025] In a specific example, the single-layer groove 2 includes a plurality of battery cell accommodating grooves 201 , and the inner edges of the openings of the battery cell accommodating grooves 201 are provided with chamfers 2011 that are made obliquely inward from top to bottom.

[0026] The opening of the battery cell receiving groove of the present embodiment is formed into a trumpet-shaped shape by chamfering obliquely inward from top to bottom, so that the battery cell can be easily placed in the battery cell receiving groove.

[0027] In a specific example, the chamfer 2011 width is less than 1 / 2 of the groove frame thickness, and the chamfer 2011 depth is less than or equal to the groove depth; the inner groove edges of the battery cell accommodating groove 201 are arc-shaped grooves 2012, and the radius of the arc-shaped grooves 2012 is less than 1 / 2 of the groove frame thickness.

[0028] The chamfered inner groove sidewalls of the battery cell receiving groove of this embodiment and the arc-shaped grooves on the edges around the inner groove can reduce the contact between the R corner of the battery cell shell and the battery cell receiving groove, preventing the top patch from warping up due to vibration and scratching.

[0029] In a specific example, a semicircular notch 2013 is provided in the middle of both sides of the battery cell accommodating groove 201 , and the radius of the semicircular notch 2013 is smaller than the inner groove depth and 1 / 2 of the inner groove length.

[0030] The radius of the semicircular notch in this embodiment needs to meet the following requirements at the same time: 1. The radius is smaller than the depth of the inner groove, 2. The radius is smaller than 1 / 2 of the length of the inner groove; the semicircular notch can be connected to the external environment, and air circulation can reduce the temperature difference between the inside and outside, thereby reducing the possibility of condensation water.

[0031] In a specific example, two tab grooves 2014 are provided at the bottom of the inner groove of the battery cell accommodating groove 201 .

[0032] The tab grooves of this embodiment can provide placement locations for the tabs of the battery cell, thereby improving the safety of battery cell storage.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
