【物品用途】;本創作是一種關於包覆手機等行動通訊設備之四周與後背之保護殼體設計。;【創作特點】;本創作之殼體外觀為適配於手機等行動通訊設備造型之矩形架構，殼體主要組成部品為，前後兩件矩形且中央鏤空之鋁合金金屬框架組合而成，靠近螢幕且體積較大之部件稱之為前框，另外一體積較小之部件為後框。前後兩框可利用底部靠近喇叭孔位置的卡勾設計作定位之後，利用上端靠近電源鍵之卡扣組合起來。組合起來之後外觀呈現一前後框皆有一完整迴圈之斜角的曲面造型，並在兩迴圈斜角面之間以微微隆起的迴圈曲面做造型上的聯結，可提供使用者較舒適之握持感並在視覺上呈現輕薄之修飾效果。另外在前框之部件，在其側邊設計了長細橢圓型的音量鍵與靜音鍵，方便使用者去執行音量切換的動作。頂端之電源鍵之設計，為一與卡扣融合而成的一體化設計，卡扣之區域有複數突起粒狀造型，提供使用者在推撥卡扣時適切的摩擦力。以手機螢幕向下之方位，卡扣向左推移時，便能釋放前後框體的組合狀態，前後框體閉合時，卡扣會自動向右推移，並將電源鍵定位。在框架體部的出音孔設計，造型為長條狀之橢圓孔，並在其孔內之面鑽探了負數矩陣排列之細孔，呈現一多數視覺陣列之美感。在其側的耳機孔之設計，別出心裁地在挖除一圓形空間之後，另外搭上一件具有內凹複曲面之圓柱體作為裝飾，並在柱體其側延伸出手機吊飾孔之設計。另外在後框之部位，預留了組合背蓋之間隙與卡勾，可方便使用者挑選合適的背蓋之後自行組裝搭配。此適配於手機並融合了人因工程與獨到美學之高度工藝技術產品造型，堪稱為一新穎且獨特的外觀設計，而符合新式樣專利標的。;上述說明僅供輔助瞭解本創作而非用以限制其內容，新式樣專利範圍係以圖面所示者為準。[Item Usage] This creation is a protective shell design that covers the sides and back of mobile communication devices such as mobile phones. [Design Features] The shell of this creation is a rectangular structure that fits the shape of mobile communication devices such as mobile phones. The shell is mainly composed of two rectangular aluminum alloy metal frames with a hollow center. The larger part close to the screen is called the front frame, and the smaller part is the rear frame. The front and rear frames can be positioned using the hook design near the speaker hole at the bottom, and then assembled using the buckle at the top near the power button. When assembled, the appearance presents a curved surface with a complete loop angle on both the front and rear frames, and a slightly raised loop curve is used to connect the two loop angle surfaces, which can provide users with a more comfortable grip and visually present a light and thin modification effect. In addition, on the side of the front frame, a long and thin oval volume button and mute button are designed to facilitate users to perform volume switching actions. The design of the power button on the top is an integrated design that is integrated with the buckle. The buckle area has multiple protruding granular shapes to provide users with appropriate friction when pushing the buckle. With the phone screen facing downward, when the buckle is pushed to the left, the front and rear frames can be released from their combined state. When the front and rear frames are closed, the buckle will automatically move to the right and position the power button. The sound outlet design on the frame body is shaped as a long elliptical hole, and the surface inside the hole is drilled with fine holes arranged in a negative matrix, presenting a multi-visual array of beauty. The design of the headphone hole on its side is ingenious. After digging out a circular space, a cylinder with a concave complex surface is placed as decoration, and the design of a mobile phone pendant hole extends from the side of the cylinder. In addition, the gap and hook for the combination of the back cover are reserved in the rear frame, which can facilitate users to select the appropriate back cover and assemble it by themselves. This highly technological product design that is suitable for mobile phones and combines ergonomics and unique aesthetics can be regarded as a novel and unique appearance design, and is in line with the subject matter of the new design patent. The above description is only used to assist in understanding this creation and is not intended to limit its content. The scope of the new design patent is subject to that shown in the drawings.
