【物品用途】;本設計有關於一種行動電源之部分，尤指一種可供儲存電力之可攜式電能儲存裝置。;【設計說明】;本設計係一種有關行動電源的設計之部分的設計，特別是具有如圖式所示之形狀者。本設計在外觀上的主要特點在於，行動電源的表面以流水般的扭轉線條組成，予人圓潤層疊之視覺觀感。;請參閱立體圖1、立體圖2、左側視圖、右側視圖、俯視圖及仰視圖，行動電源表面的流線圖形除予人圓潤流水般之造型感外，進一步產生層進式的視覺印象。;接著，請復參閱立體圖1及立體圖2，行動電源整體被流水般的線條切割為數個部分，連續的線條元素勾勒出產品的層次變化及立體感。;另外，請復參閱立體圖1、立體圖2、前視圖及俯視圖，行動電源的開關在側面之設計，使整體造型更具延續性，並進一步體現本設計奢華亮眼的美感。此外，也能進一步避免誤觸行動電源之開關。;整體觀之，本設計極具巧思，為立體造型上凹凸有致之設計，線條上顯剛柔並濟、圓潤簡約，使本設計成為美觀實用的工藝產品。;圖式所揭露之虛線部分，為本案不主張設計之部分。[Use of article]; This design relates to a mobile power source, specifically a portable electrical energy storage device that can store electricity. ;[Design Description];This design is a design related to the design of a mobile power supply, especially one with a shape as shown in the figure. The main appearance feature of this design is that the surface of the power bank is composed of flowing twisting lines, giving people a rounded and layered visual impression. ; Please refer to the three-dimensional view 1, the three-dimensional view 2, the left view, the right view, the top view and the bottom view. The streamlined graphics on the surface of the power bank not only give people a rounded and flowing shape, but also create a layered visual impression. ; Next, please refer to the perspective view 1 and perspective view 2 again. The entire mobile power supply is cut into several parts by flowing lines. The continuous line elements outline the layer changes and three-dimensionality of the product. ; In addition, please refer to the perspective view 1, perspective view 2, front view and top view. The switch of the mobile power supply is designed on the side to make the overall shape more consistent and further reflect the luxurious and eye-catching beauty of this design. In addition, it can further avoid accidentally touching the power switch of the mobile phone. ; Viewed as a whole, this design is very ingenious. It is a three-dimensional design with concave and convex shapes. The lines are rigid and soft, rounded and simple, making this design a beautiful and practical craft product. ; The dotted line portion disclosed in the diagram is the portion of the case that is not intended to be designed.
