Description
Technical Field
The utility model relates to a lithium ion battery technical field, concretely relates to lithium ion battery shell.
Background
At present, a large-capacity lithium ion battery in the market is large in size and heavy in weight, and a metal plate is often selected as a shell on the shell. The sheet metal shell has intensity well, and the anti advantage that falls of anti vibration, but the precision is compared and is moulded the shell poor, can't adopt to mould the waterproof mode in gluey groove of beating that the shell often used, consequently adopts the panel beating as the waterproof performance of shell to hand over, and the application provides a lithium ion battery shell for this reason and solves the waterproof problem that adopts the panel beating as the shell.
Disclosure of Invention
According to the problem that the background art provided, the utility model provides a lithium ion battery shell solves, it is right next the utility model discloses do further to explain.
A lithium ion battery shell comprises an upper shell and a lower shell, wherein a waterproof pad is arranged between the upper shell and the lower shell, two 90-degree edge folding treatments are performed on the periphery of the upper shell to form a first edge folding and a second edge folding, one 180-degree edge folding treatment is performed on the periphery of the upper end of the lower shell, and then one 90-degree edge folding treatment is performed to form a third edge folding and a fourth edge folding;
preferably, the width of the gap is 0.5mm;
preferably, the upper shell and the lower shell are fixedly connected through bolts;
preferably, the bolt is a countersunk bolt;
preferably, four bolts are arranged on each side of the upper shell and the lower shell;
preferably, the upper shell is also provided with a handle convenient to carry;
preferably, the middle of the handle is provided with an anti-slip sleeve;
has the advantages that: compared with the prior art, the utility model discloses it has sealed glue to coat in the space, makes the shell increase a layer of waterproof layer in the vertical direction, and this waterproof layer is for sealed glue solidify gradually after being extruded in the space, and the adhesion is strong after the solidification, and stress is little, is difficult for taking place plastic deformation, and waterproof performance is more reliable, and this application has two waterproof measures of silica gel waterproof pad and sealed glue, seals waterproof respectively at the horizontal plane and the vertical face of shell; when the waterproof pad is subjected to plastic deformation and loses waterproof capability, the gluing surface can still provide reliable waterproof for the battery;

FIG. 3: the utility model isbase:Sub>A schematic cross-sectional view A-A;
FIG. 4: the utility model discloses an enlarged schematic diagram of the structure at B;
in the figure: the waterproof structure comprises an upper shell 1, a lower shell 2, a waterproof pad 3, a first folded edge 4, a second folded edge 5, a third folded edge 6, a fourth folded edge 7, a gap 8, a sealant 9, a bolt 10 and a handle 11;
Detailed Description
A specific embodiment of the present invention will be described in detail with reference to fig. 1-4.
The utility model provides a lithium ion battery shell, includes epitheca 1 and inferior valve 2 epitheca 1 with be equipped with waterproof pad 3 between the inferior valve 2, through pushing down epitheca 1 with waterproof pad 3 between the inferior valve 2 accomplishes waterproof function, but waterproof pad 3 can take place the creep under the effect of long-time compressive stress, takes place plastic deformation, lead to waterproof pad with epitheca 1 with produce small gap between the inferior valve 2, lead to the sealing performance and the waterproof performance of whole shell to weaken, take following measure for this application: performing 90-degree edge folding treatment twice on the periphery of the upper shell 1 to form a first folded edge 4 and a second folded edge 5, performing 180-degree edge folding once on the periphery of the upper end of the lower shell 2, and performing 90-degree edge folding once again to form a third folded edge 6 and a fourth folded edge 7, wherein the waterproof pad 3 is placed between the second folded edge 5 and the fourth folded edge 7, a gap 8 is arranged between the first folded edge 4 and the third folded edge 6, the gap is preferably 0.5mm in width, and the gap 8 is filled with a sealant 9; in the process of pressing the upper shell 1 and the lower shell 2 downwards, the waterproof pad 3 extrudes the sealant 9 into the gap 8 to fill the gap 8, and after the sealant is cured, a waterproof layer in the vertical direction is formed; it should be noted that the waterproof pad 3 is made of a silica gel material;
in this embodiment, the upper shell 1 and the lower shell 2 are fixedly connected by a bolt 10, preferably, the bolt 10 is a countersunk head bolt; four bolts 10 are arranged on each side of the upper shell 1 and the lower shell 2;
in this embodiment, the upper shell 1 is further provided with a handle 11 convenient to carry, and preferably, an anti-slip sleeve is arranged in the middle of the handle 11;
compared with the prior art, the utility model discloses it has sealed glue to coat in the space, makes the shell increase a layer of waterproof layer in the vertical direction, and this waterproof layer is for sealed glue solidify gradually after being extruded in the space, and the adhesion is strong after the solidification, and stress is little, is difficult for taking place plastic deformation, and waterproof performance is more reliable, and this application has two waterproof measures of silica gel waterproof pad and sealed glue, seals waterproof respectively at the horizontal plane and the vertical face of shell; when the waterproof pad is subjected to plastic deformation and loses waterproof capability, the gluing surface can still provide reliable waterproof for the battery;
the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
