Detailed Description
For the purpose of better explaining the present invention and to facilitate understanding, the present invention will be described in detail by way of specific embodiments with reference to the accompanying drawings.
As shown in fig. 1 to 3, an end face seal ring structure of a battery plastic casing according to an embodiment of the present invention includes: the sealing ring comprises a sealing ring body 1, wherein the sealing ring body 1 is annular, a plurality of abdicating holes 11 for avoiding screws 21 on a battery plastic shell 2 are arranged on the sealing ring body 1 at intervals, and annular reinforcing ribs 12 matched with inner side edges 22 on the battery plastic shell 2 are formed on the lower surface of the sealing ring body 1 in a downward protruding mode; the sealing ring body 1 is provided with a plurality of positioning and mounting holes 13 at intervals, which are used for being matched with the limiting columns 23 on the battery plastic shell 2.
Specifically, a plurality of protrusions 14 clamped with the battery plastic shell 2 are arranged on the sealing ring body 1 at intervals; the bulges 14 and the annular reinforcing ribs 12 are integrated into a whole, the strength of the annular reinforcing ribs 12 is further enhanced, and meanwhile, the bulges 14 and the battery plastic shell 2 are in tight fit, so that the whole sealing ring is clamped on the battery plastic shell 2 and is not easy to drop.
In the embodiment, the positioning mounting hole 13 is matched with the limiting column 23, so that the sealing position can be accurately positioned, and the adverse effect of the tensile deformation of the sealing ring on the sealing performance is reduced; the bulge 14 is matched with the battery plastic shell 2, interference fit can be carried out on the battery plastic shell, and the sealing ring is prevented from falling off in the assembling process.
When in use, as shown in fig. 4, the sealing ring is assembled on the battery plastic shell 2, and the abdicating hole 11 is matched with the screw 21 on the battery plastic shell 2; the annular reinforcing rib 12 and the battery mould the inboard side 22 on the shell 2 and cooperate and form the encapsulated situation, protruding 14 and battery mould the shell 2 looks block simultaneously, further make annular reinforcing rib 12 and the battery mould the inboard side 22 on the shell 2 and cooperate more closely, simultaneously, protruding 14 and battery mould the tight fit of shell 2, make whole sealing washer card locate the battery mould the shell 2 on, be difficult for dropping.
The above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made in accordance with the claims of the present invention should be covered by the present invention.
