Description

Novel O-ring inner fin

Technical Field

The utility model belongs to the technical field of inner fins, and relates to a novel O-ring inner fin.

Background

The outer fin O-ring is developed, improved and used by Taiwan Jiapu battery development team, the O-ring design Guide Line to date, the main structure of the O-ring comprises a base material and an outer fin, and the main functions of the outer fin comprise:

filling gap on the substrate and the shell structure;

the structure meets the assembly requirement.

However, with the continuous production of the battery, new problems start to emerge, and the analysis shows that the air leakage phenomenon also occurs between the O-ring substrate surface and the waterproof wall of the plastic part, and the air leakage position is concentrated at the bending transition position of the end cover, so that the waterproof requirement of the battery cannot be met only by tightly attaching the substrate and the waterproof wall of the end cover; through the confirmation of the 3D scanner, the deviation exists between the structure of the plastic part waterproof wall in bending transition and the design value, so that the pressing amount between the base material and the waterproof wall cannot meet the expected design requirement. Through continuous verification of the Taipu engineering team, the design of the inner fins is developed, and the new structure is to add the inner fins of the whole circle in the base material on the basis of the outer fins, so as to solve the problem that the water seepage phenomenon occurs due to insufficient local pressing amount caused by the fact that the waterproof wall of the end cover is not tightly combined with the O-ring.

With the increasing types of batteries, the O-ring design of the outer fins cannot meet the waterproof requirement of the batteries, more and more batteries are analyzed as the phenomenon of air leakage between the waterproof wall of the end cover and the O-ring, and therefore the design of the inner fins tends to be great.

Disclosure of Invention

The utility model aims to provide a novel O-ring inner fin to solve the problems in the background technology.

The aim of the utility model can be achieved by the following technical scheme: the novel O-ring inner fin comprises an inner fin body and eight square connecting blocks, wherein two semicircular concave transition pieces formed integrally are arranged on two sides of the inner fin body, the top and the bottom of the inner fin body and the four semicircular concave transition pieces are fixedly provided with extension connecting columns, and the number of the extension connecting columns is eight and one-to-one connected with the square connecting blocks.

In the novel O-ring inner fin, the outer ring of the inner fin body is fixedly provided with the outer sealing grooves, and the number of the outer sealing grooves is two.
