SMART DEVICE AND METHOD FOR CHANGING BATTERY PACK WITHOUT SYSTEM OFF USING HINGE ELECTRODE

摘要

A method for replacing a working battery and a supplementary battery without cutoff of electric power comprises the following steps: rotating a hinge accommodated in a rear surface of a body of a smart device by 30 to 60° from the rear surface of the body, when the smart device having the body equipped with a body electrode and having the hinge rotated on the body and equipped with a replacement electrode is alternately operated by means of power of a working battery and a supplementary battery respectively including a side surface main electrode and an upper surface assisting electrode; connecting the assisting electrode of the supplementary battery to the replacement electrode while the main electrode of the working battery is connected to the body electrode; releasing connection of the body electrode with the main electrode of the working battery; releasing the main electrode of the supplementary battery to the body electrode by rotating the hinge by 180° from the rear surface of the body; and releasing connection of the replacement electrode with the assisting electrode of the supplementary battery by rotating the hinge to the rear surface of the body.
