Background

The lithium ion battery is put into the plastic uptake box during transportation and storage, and then the plastic uptake boxes are mutually overlapped and placed, so that the plastic uptake box needs to be designed reasonably. The plastic uptake boxes which are generally used in the market can be placed in the same direction, and the operation is convenient. However, through the layer-by-layer stacking of the plastic uptake boxes, the bottom of the upper plastic uptake box can contact the surface of the lithium ion battery in the lower plastic uptake box, the surface of the lithium ion battery in the lower plastic uptake box can be scraped, the plastic uptake boxes can be stacked layer by layer so that the weight of the lithium ion battery can be stacked layer by layer, the lithium ion battery in the bottom plastic uptake box has a pressure injury risk, and a battery safety accident can occur. People want a plurality of methods for solving the problem, and the mainstream method is to design buckles at the peripheral edge of the plastic-absorbing box and in the lithium ion battery groove, so that the buckles can be used for preventing the lithium ion battery groove of the upper layer of the plastic-absorbing box from directly contacting the surface of the lithium ion battery of the lower layer. However, as the number of stacked layers increases, the buckle has a failure risk, and the lithium ion battery with the bottom layer is still scratched and crushed by the upper plastic-suction box; meanwhile, the buckle design is complex, and the manufacturing cost of the plastic uptake box is increased, so that the plastic uptake box for preventing the surface of the lithium ion battery from being scratched and crushed is needed to be developed.

the utility model provides a prevent plastic uptake box of lithium ion battery surface scratch and crushing wound, the plastic uptake box comprises peripheral A, lithium ion battery groove B, tie-beam C between peripheral A and the lithium ion battery groove B, tie-beam D between the lithium ion battery groove B, the peripheral bottom and the lithium ion battery groove bottom of plastic uptake box are at same survey, but not at same horizontal plane, and the peripheral degree of depth h of plastic uptake box is greater than lithium ion battery groove degree of depth h1 promptly, and when using the plastic uptake box, the lithium ion battery groove head of upper strata plastic uptake box aligns with the lithium ion battery groove afterbody of lower floor's plastic uptake box and stacks.

And the peripheral depth h = the nominal thickness of the lithium ion battery +1/3 the depth h1 of the lithium ion battery groove.

The depth h1 of the lithium ion battery groove is equal to the nominal thickness of the lithium ion battery plus 4 mm.

The bottom of the periphery A also comprises a horizontally extending edge E which is convenient to take and is 5mm wide.

The lithium ion battery groove is composed of a lithium ion battery main body groove and a pole lug groove.

The plastic uptake box is made of one of PVC, PET and PS.

The wall thickness of the plastic uptake box is 0.4 mm-0.6 mm, and the plastic uptake box is square or rectangular.

When the lithium ion battery storage box is used, the head of the lithium ion battery groove of the first layer of plastic uptake box is placed upwards, after the lithium ion battery is filled in all the lithium ion battery grooves of the plastic uptake box, the head of the lithium ion battery groove of the second layer of plastic uptake box is downward aligned with the tail of the lithium ion battery groove of the first layer and placed on the front side, the lithium ion battery is filled in the empty lithium ion battery groove, the placing mode of the plastic uptake box of the first layer is repeated, each layer of plastic uptake box is placed on top of the other, the lithium ion battery grooves of each layer of plastic uptake box are not overlapped, the bottom of the plastic uptake box of the upper layer cannot be contacted with the surface of the lithium ion battery of the lower layer, and the influence on the appearance of the battery caused by the scraping of the surface of the lithium ion battery of the lower layer of the plastic uptake box at the bottom of the plastic uptake box of the upper layer is avoided. Because the peripheral bottom and the lithium ion battery groove are not in the same horizontal plane, the next layer of plastic-absorbing box is fixed on the periphery of the upper layer of plastic-absorbing box, the plastic-absorbing box is prevented from sliding, and simultaneously, the battery grooves of each layer of plastic-absorbing box are not overlapped, and the problem that the safety performance of the battery is influenced due to the fact that the bottom battery is crushed or deformed because the lithium ion battery on the bottommost layer is extruded by the lithium ion battery on the upper layer in the stacking process of the plastic-absorbing boxes is also avoided.
