Dry and wet sealing performance detection instrument for new energy battery box body

Abstract

The invention discloses a dry and wet sealing performance detection instrument for a new energy battery box body, and relates to the technical field of new energy batteries. The dry and wet sealing performance detection instrument for the new energy battery box body comprises a new energy battery box. The new energy battery box comprises a box body, the middle part of the upper surface of the box body is provided with an air hole, the interior of the air hole is in threaded connection with an air-tight cover, the air-tight cover is matched with the air hole, and the outer side of the upper end of the air-tight cover is fixedly connected with an air blocking cushion, and the air blocking cushion tightly applies to the upper surface of the box body. An air tightness device is arranged above the new energy battery box and comprises a ventilation column, deep threads are formed in the outer side of the ventilation column, a movable ring is connected to the outer side of the ventilation column in a sleeving mode, pull ropes are evenly and fixedly connected to a lower end opening of the movable ring at equal intervals, and the pull ropes are made of elastic materials. According to the dry and wet sealing performance detection instrument for the new energy battery box body, the detection accuracy of the device is greatly improved.

Description

technical field [0001] The invention relates to the technical field of new energy batteries, in particular to a dry and wet sealing test instrument for a new energy battery box. Background technique [0002] The power battery is the power source that provides the power source for the tool. It mostly refers to the battery that provides power for electric vehicles, electric trains, electric bicycles, and golf carts. It is mainly different from the starting battery used to start the car engine. For normal use, it is necessary to conduct a dry and wet sealing test on the box storing the new energy battery. [0003] At present, the wet and dry seal test of most new energy batteries on the market is completed through separate steps. When performing dry and wet seal test, it is usually necessary to immerse the new energy battery box in water and observe the bubbles in the box. It should be noted that the primary task of the airtightness test is to first ensure the airtightness of ...

[0003] At present, the wet and dry seal detection of most new energy batteries on the market is completed through separate steps. When performing the dry and wet seal test, it is usually necessary to immerse the new energy battery case in water and observe the appearance of bubbles in the water. It should be noted that the primary task of the airtightness test is to first ensure the airtightness of the access position of the detection unit. The way of fastening and adding sealing gaskets is to realize the airtight connection between the airtight device and the new energy battery casing, but this kind of connection operation is cumbersome and the sealing effect is not very ideal, which makes it inconvenient to test the airtightness
