The slot 241 is recessed inwardly from the surface of the bottom housing 231 and extends upwardly a distance so that the device sheath 20 can be fitted over the charging plane 124 for charging to accurately position the coil.

請參閱第三圖,在其他實施例中,本體12可以是一種平板結構,使得無線充電座10可以垂直吊掛在牆上,或是透過立架結構支撐於平面上,使其垂直固定於桌面上,電子設備即可透過嵌合方式井然有序地排列在平板表面上。 Referring to the third figure, in other embodiments, the body 12 can be a flat structure, so that the wireless charging stand 10 can be vertically suspended on the wall or supported on the plane through the vertical structure to be vertically fixed to the desktop. In this way, the electronic devices can be arranged in an orderly manner on the surface of the flat plate through the fitting method.

請參閱第四圖,在另一實施例中,本體12設置為椎體,並且簡化第一對嵌部13與第二對嵌部24的結構,使第一對嵌部13設置為一垂直延伸的凸塊132,第二對嵌部24設置為配合凸塊132的凹槽242,使得裝置護套20安裝後會傾斜一角度,因此,裝置護套20藉由自身重力以及凸塊132和凹槽242干涉而固定於充電平面區124上,此嵌合結構使裝置護套20更容易固定於充電平面區124上,可以提供使用者更方便取用的手感。進一步,凸塊132選擇為磁鐵133,凹槽242 底部設置一金屬薄片243,使嵌合更穩固。 Referring to the fourth figure, in another embodiment, the body 12 is disposed as a vertebral body, and the structure of the first pair of the embedded portion 13 and the second pair of the embedded portion 24 is simplified, so that the first pair of the embedded portions 13 are disposed as a vertical extension. The bumps 132, the second pair of inserts 24 are arranged to fit the recesses 242 of the bumps 132, so that the device sheath 20 is tilted at an angle after installation, so that the device sheath 20 is supported by its own gravity and the bumps 132 and concaves The slot 242 interferes and is secured to the charging plane 124. This mating structure allows the device sheath 20 to be more easily secured to the charging plane 124, providing a more convenient feel for the user. Further, the bump 132 is selected as a magnet 133, and the groove 242 A metal foil 243 is provided at the bottom to make the fitting more stable.

綜上所述,無線充電裝置組合1是利用無線充電座10的充電平面區124設置為傾斜或是直角的接觸角度與裝置護套20接觸,並藉由凸設於充電平面區124的第一對嵌部13與形成於裝置護套20的凹陷狀第二對嵌部24互相卡合,而令使用者在置放裝置護套20時可以用直覺判斷來尋找嵌合位置,並可確保接收線圈221與傳送線圈111可以完全重疊。再者,將充電平面區124設置為非水平面可節省無線充電座10所占用的的平面空間,在增加側表面123的高度後,還可增加無線充電座10承接裝置護套20的數量,從而使更多的電子設備同時充電,能夠有效運用於任何具有垂直或是傾斜表面的物體上。 In summary, the wireless charging device assembly 1 is in contact with the device sheath 20 by using the charging plane region 124 of the wireless charging stand 10 to be inclined or at a right angle, and is firstly protruded from the charging plane region 124. The fitting portion 13 and the concave second pair of fitting portions 24 formed on the device sheath 20 are engaged with each other, so that the user can intuitively judge the fitting position when placing the device sheath 20, and can ensure reception. The coil 221 and the transmitting coil 111 may completely overlap. Moreover, setting the charging plane area 124 to a non-horizontal plane can save the plane space occupied by the wireless charging stand 10. After increasing the height of the side surface 123, the number of the charging device 10 of the wireless charging stand 10 can also be increased, thereby By charging more electronic devices at the same time, it can be effectively applied to any object with a vertical or inclined surface.
