A newly filed patent (Publication Number: US20240039109A1) describes a battery housing structure designed to securely accommodate a battery cell. The housing is a tubular structure with an opening at one end, where an end plate is mounted to create an accommodation space for the battery cell. A first sealing element is positioned between the end plate and the housing to ensure the space is hermetically sealed. The end plate features a plate body with a tapered guide portion and a mounting groove for the sealing element, which includes bulges for a secure fit. Additionally, a second sealing element is located outside the first one, with a stopping flange and stopper to control insertion depth.
Furthermore, the patent details the inclusion of sealing lips on the first sealing element, arranged in parallel along the opening's plane. The end plate also comprises a connecting portion with mounting holes for external structure attachment. A cable containment system assembly with a fender and conductive connecting strip is included in the battery housing structure, electrically connected to the battery cell's electrode post. The patent also covers the battery itself, an electrical device incorporating the battery, and a method for manufacturing the battery housing structure, emphasizing the importance of a hermetically sealed accommodation space for multiple battery cells within the tubular housing.
