一种电源设备，包括一本体、一电池、一金属环、一盖体、一连接部及一金属顶板。本体内部形成一容置腔，本体表面形成一连通容置腔的开口。电池设置于容置腔内。金属环设置于开口周围。盖体覆盖容置腔以及开口周围的金属环，金属环系透过高周波加热以将本体与盖体融合。连接部设置于本体或盖体上并连接电池。金属顶板设置于容置腔内并覆盖于电池受到高周波加热之一侧。本发明电源设备借由高周波对金属环加热，使金属环周围的盖体与本体相融为一体，使电池完全密封在本体内，且金属顶板覆盖电池以阻隔高周波能量，防止电池不被高周波损坏。

A power device comprises a main body, a battery, a metallic ring, a cover, a connecting portion and a metallic plate. The main body is formed a cavity therein for receiving the battery, and an opening on a surface thereof. The opening is connected to the cavity. The metallic ring is disposed around the opening. The cavity and the metallic ring are covered by the cover. The metallic ring is heated by the high-frequency heating for fusion of the main body and the cover. Therefore, the battery is sealed inside the main body. The connecting portion connected to the battery can be arranged on the main body or cover. The metallic plate is disposed in the cavity and covered the battery to prevent the battery from being broken by the high-frequency heating.
