Description

A package structure that facilitates cell replacement of a built-in battery of an electronic device

The following embodiments facilitate cell replacement of a built-in battery of an electronic device manufactured based on 3D printing to have a predetermined structure so as to more easily replace a battery cell embedded in an electronic device including a battery such as a vacuum cleaner. It's about the package structure that does.

As the charging speed of batteries becomes very fast and technologies related to batteries, such as capacity improvement and weight reduction of batteries, develop, various household/commercial electronic devices are converted from wired devices to wireless devices and are being developed.

However, these batteries function as consumables, such that performance decreases each time they are charged and discharged, and depending on the product, the battery swells or becomes unusable.

Conventional batteries for electronic devices are provided in the form of a predetermined battery package containing a predetermined circuit board and battery cell therein, and consumers/users must visit a service center to repair the battery and replace the entire battery package. However, there was a problem that the repair cost was high and a lot of waste was generated due to replacement.

In addition, the casings of general battery packages are integrated with technologies such as thermal fusion/ultrasonic bonding so that consumers/users cannot open or disassemble them, so only the battery cells inside can be used unless the casing is damaged using a tool such as a cutter. There was a limit that could not be replaced.
