A dry and wet sealing test instrument for a new energy battery box

Abstract

The invention discloses a dry-wet sealing test instrument for a new energy battery box, and relates to the technical field of new energy batteries. The dry-wet airtightness testing instrument for a new energy battery box includes a new energy battery box. The air-tight cover is adapted to the air hole. The air-tight cover is fixedly connected with an air-blocking cushion on the outer side of the upper end. The air-blocking cushion closely fits the upper surface of the box. An air-tight device is installed above the new energy battery box. The airtight device includes a ventilation column, and the outer side of the ventilation column is provided with deep threads, and the outer side of the ventilation column is sleeved with a moving ring, and the lower port of the moving ring is equidistantly and evenly fixedly connected with a drawstring, and the material of the drawstring includes elastic material. The dry and wet sealing test instrument for the new energy battery box greatly improves the detection accuracy of the device.

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 ...

Problems solved by technology

[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
