Abstract
Description
本發明是有關於一種電子構件,且特別是有關於一種電池模組。The present invention relates to an electronic component, and particularly to a battery module.
隨著現今科技的進步,由於筆記型電腦的功能日益茁壯,且其體積越來越小也便於攜帶,因此已成為消費性電子產品的市場主流。With the advancement of today's technology, notebook computers have become the mainstream of the consumer electronic product market due to their increasingly robust functions, smaller size and portability.
筆記型電腦包含裝設於其主機的電池模組,用以提供筆記型電腦運行所需電力。所述電池模組以框體來容納電池單元,且框體內具有肋條以隔離相鄰的電池單元。此外,各電池單元外表包覆了鋁塑膜以避免電池漏液。然而,鋁塑膜在各電池單元的側邊接合而形成了凸緣,這些凸緣及肋條並排導致電池模組整體寬度增加,不利於電池模組體積的縮減。The notebook computer includes a battery module installed on the host computer to provide the power required for the operation of the notebook computer. The battery module uses a frame to accommodate battery cells, and the frame has ribs to isolate adjacent battery cells. In addition, the exterior of each battery unit is covered with aluminum-plastic film to avoid battery leakage. However, the aluminum-plastic films are joined on the sides of the battery cells to form flanges, and the juxtaposition of these flanges and ribs leads to an increase in the overall width of the battery module, which is not conducive to reducing the volume of the battery module.
本發明提供一種電池模組,可具有較小的寬度。The present invention provides a battery module which can have a smaller width.
本發明的電池模組包括一框體及至少二電池單元。框體包括一外框及至少一肋條,其中肋條連接於外框而位於外框內。電池單元配置於外框內,其中肋條位於二電池單元之間,各電池單元包括一主體部及從主體部延伸出的至少一凸緣部,一電池單元的凸緣部至少部分地重疊於另一電池單元的凸緣部而在二電池單元之間形成一彎曲狀間隙,且肋條呈彎曲狀而沿彎曲狀間隙延伸。The battery module of the present invention includes a frame body and at least two battery units. The frame body includes an outer frame and at least one rib, wherein the rib is connected to the outer frame and located in the outer frame. The battery cells are arranged in the outer frame, wherein the ribs are located between the two battery cells, each battery cell includes a main body portion and at least one flange portion extending from the main body portion, and the flange portion of one battery cell at least partially overlaps the other. The flange portion of one battery unit forms a curved gap between the two battery units, and the rib is curved and extends along the curved gap.
在本發明的一實施例中,上述的至少二電池單元之間的距離小於各凸緣部的長度的兩倍。In an embodiment of the present invention, the distance between the above-mentioned at least two battery cells is less than twice the length of each flange portion.
在本發明的一實施例中,上述的各電池單元包括一電池本體及一包覆膜,包覆膜包覆電池本體且在電池本體的側邊形成至少一凸緣部。In an embodiment of the present invention, each of the above-mentioned battery cells includes a battery body and a coating film, and the coating film covers the battery body and forms at least one flange portion on the side of the battery body.
在本發明的一實施例中,上述的包覆膜是鋁塑膜。In an embodiment of the present invention, the above-mentioned coating film is an aluminum plastic film.
在本發明的一實施例中,上述的肋條包括一水平區段及兩垂直區段,兩垂直區段分別連接於水平區段的相對兩端,且兩垂直區段分別沿相反的兩方向延伸。In an embodiment of the present invention, the rib includes a horizontal section and two vertical sections, the two vertical sections are respectively connected to opposite ends of the horizontal section, and the two vertical sections extend in opposite directions respectively .
在本發明的一實施例中,上述的各垂直區段與水平區段之間具有圓角。In an embodiment of the present invention, each of the above-mentioned vertical sections and horizontal sections has rounded corners.
在本發明的一實施例中,上述的水平區段及兩凸緣部至少部分地重疊。In an embodiment of the present invention, the above-mentioned horizontal section and the two flange portions at least partially overlap.
在本發明的一實施例中,上述的各垂直區段位於一電池單元的主體部與另一電池單元的凸緣部之間。In an embodiment of the present invention, each of the above-mentioned vertical sections is located between the main body portion of one battery cell and the flange portion of the other battery cell.
在本發明的一實施例中,上述的各垂直區段的長度小於水平區段的長度。In an embodiment of the present invention, the length of each vertical section is smaller than the length of the horizontal section.
在本發明的一實施例中,上述的各電池單元的主體部與至少一肋條之間具有間隙。In an embodiment of the present invention, there is a gap between the main body of each of the above-mentioned battery cells and the at least one rib.
在本發明的一實施例中,上述的各電池單元的至少一凸緣部與至少一肋條之間具有間隙。In an embodiment of the present invention, there is a gap between at least one flange portion and at least one rib of each of the above-mentioned battery cells.
在本發明的一實施例中,上述的電池模組包括一電路板,其中電路板配置於外框且電性連接各電池單元。In an embodiment of the present invention, the above-mentioned battery module includes a circuit board, wherein the circuit board is disposed on the outer frame and is electrically connected to each battery unit.
基於上述,在本發明的電池模組中,相鄰的兩電池單元的凸緣部彼此重疊,而可有效縮減電池模組的整體寬度。因相鄰的兩電池單元的凸緣部彼此重疊使得兩電池單元之間的間隙成為彎曲狀,故本發明將用以隔離電池單元的肋條相應地設計成彎曲狀,讓肋條能夠順應所述彎曲狀的間隙延伸而位於兩電池單元之間,從而使相鄰的兩電池單元相互隔離。Based on the above, in the battery module of the present invention, the flange portions of two adjacent battery cells overlap each other, thereby effectively reducing the overall width of the battery module. Since the flanges of two adjacent battery cells overlap each other, the gap between the two battery cells is curved. Therefore, the present invention designs the ribs used to isolate the battery cells to be curved accordingly, so that the ribs can conform to the curved shape. A gap in the shape of a battery extends and is located between the two battery cells, so that the two adjacent battery cells are isolated from each other.
為讓本發明的上述特徵和優點能更明顯易懂,下文特舉實施例,並配合所附圖式作詳細說明如下。In order to make the above-mentioned features and advantages of the present invention more obvious and easy to understand, the following embodiments are given and described in detail with the accompanying drawings as follows.
