Detailed Description

The present application will be further described with reference to the following detailed description.

The same or similar reference numerals in the drawings of the embodiments of the present application correspond to the same or similar components; in the description of the present application, it is to be understood that the terms "upper", "lower", "left", "right", "top", "bottom", "inner", "outer", and the like, if any, are used in the orientations and positional relationships indicated in the drawings only for the convenience of describing the present application and for simplicity of description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and therefore the terms describing the positional relationships in the drawings are for illustrative purposes only and are not to be construed as limiting the present patent.

Furthermore, if the terms "first," "second," and the like are used for descriptive purposes only, they are used for mainly distinguishing different devices, elements or components (the specific types and configurations may be the same or different), and they are not used for indicating or implying relative importance or quantity among the devices, elements or components, but are not to be construed as indicating or implying relative importance.

In the embodiments shown in fig. 1-3, the present application provides a waterproof structure of a case, which is applied to battery assembly and comprises a case body, an upper cover and a waterproof ring; an opening is formed in one side of the box body, and the upper cover is connected to the opening of the box body in a sealing mode through a waterproof ring; wherein, the middle part of the section of the waterproof ring is also dug with a hollow groove. In this embodiment, this application is through setting up the fretwork groove, and waterproof circle pressfitting deformation is easier when lock attaches screw or buckle span, and upper cover, box body installation are easier.

In some embodiments, the lower surface of the upper cover is dug to form a waterproof groove, the upper end of the waterproof ring is installed in the waterproof groove, and the lower end of the waterproof ring abuts against the opening of the box body. The waterproof ring and the waterproof groove are of rectangular annular structures. In this embodiment, the opening of the waterproof groove is provided with an inclined surface or an arc surface; the sectional area of the waterproof ring is larger than that of the waterproof groove. The waterproof ring is placed in the waterproof groove, and the waterproof ring is extruded and deformed in the waterproof groove to be filled between the upper cover and the box body. The depth of the waterproof groove is smaller than the height of the waterproof ring.

In some embodiments, the upper end and/or the lower end of the watertight groove is further provided with a first watertight protrusion. Waterproof circle upper end and/or lower extreme still are provided with the waterproof arch of second, and the waterproof arch of second sets up with first waterproof protruding adjacent. The cross sections of the first waterproof bulge and the second waterproof bulge are of semicircular or arc structures. In this embodiment, this application can all set up first waterproof arch, the waterproof arch of second at the upper surface or the lower surface of waterproof circle.
