Detailed Description

The utility model is further explained below with reference to the drawings and the embodiments.

It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.

As shown in fig. 1-7, the embodiment provides a dual waterproof structure of battery, including the inside drain pan 2 that is provided with battery module 1, the drain pan upper cover is equipped with face-piece subassembly 3, be provided with sealing washer 4 and adhesive tape between the seam of face-piece subassembly and drain pan, be provided with the reason wire casing 7 that is used for holding 5 pencil 6 of connector between the inside of face-piece subassembly and drain pan, sealed glue has been filled in to reason wire casing inside.

In the embodiment of the utility model, the open outer ring of the bottom shell is provided with a glue applying groove 8, the outer ring wall 9 used for being embedded into the glue applying groove from top to bottom is fixedly arranged on the outer ring of the bottom surface of the face shell assembly, and the adhesive tape is positioned in the glue applying groove.

In the embodiment of the utility model, an inner ring wall 10 is fixedly arranged on the open inner ring of the bottom shell, a sealing groove 11 embedded in the inner ring wall is arranged on the bottom inner ring of the face shell assembly, and the sealing ring is positioned in the sealing groove.
