Description

Take IPX5 waterproof construction of screw hole

Technical Field

The utility model relates to a lithium battery waterproof technology field, concretely relates to take IPX5 waterproof construction of screw hole.

Background

With the development of the lithium battery industry, more and more products need to use the lithium battery, and the lithium battery is widely used in various environments, particularly in rainy days, use scenes and the like, which have very serious test on the lithium battery and seriously affect the safety problem. Therefore, the waterproof performance and requirement of lithium batteries are more and more important.

This patent provides a take waterproof IPX5 waterproof solution in screw hole. IPX5 test requirements: nozzle-to-housing surface distances of any orientation can be tolerated: 2.5-3 m low-pressure water column, and the product has no any damage.

There are three main structural process ways to meet the waterproof requirement in the lithium battery industry:

1. the casing is sealed by the sealant, and the casing is firmly adhered together after the sealant is solidified, so that the method is simplest, and the sealant is mainly used for sealing plastic parts, thereby achieving the aim of water prevention.

2. The purpose of water proofing is achieved by utilizing the sealing coil and compressing the sealing coil through the shell, and the mode is low in cost and simple in structure.

3. The other is to seal the housing with a waterproof gasket, which is compressed by the upper and lower covers and deformed to fill the gap between the upper and lower covers, thereby achieving the waterproof purpose.

However, the above methods generally have the following disadvantages:

1. with sealed gluey sealed housing, need clear up glue when producing the line operation, the battery outward appearance is more difficult to handle, can remain sealed vestige of gluing, influences product appearance, and when the lithium cell needs maintenance, because sealed gluey viscidity ratio is stronger, combines closely with the plastic, inconvenient dismantlement, the shell is scrapped easily during the shell dismouting, and the cost is higher.

2. Utilize sealed line (circle), reach waterproof purpose through shell compression sealed line (circle), this kind of waterproof line stability and operability are relatively poor, require line footpath unanimity everywhere during the use of this kind of waterproof line, the compression capacity just can be even everywhere, thereby reach waterproof requirement, when producing the line operation, it has the drag to exempt from, make waterproof line footpath hardly keep unanimous everywhere, the compression capacity is inconsistent, the uniformity is poor, and the screw department of lid receives the restriction usually about the fastening, need adopt other modes to supply sealed, the operation is inconvenient, and be difficult to reach high waterproof requirement.

3. The waterproof gasket is used for sealing the shell, the waterproof ring is compressed by the upper cover and the lower cover, the waterproof ring deforms to fill the gap between the upper cover and the lower cover, so that the waterproof purpose is achieved, the required space of the waterproof mode is larger, the battery with the limited size cannot be adopted, and the locking screw is used for easily extruding the waterproof ring out of the outer end face of the product, so that the appearance of the product is influenced.
