As shown in fig. 27, the mounting and fixing buckle 7 of the second embodiment has the same structure except that the height of the lower hook 72 is reduced for hanging the electric cross frame 81.

As shown in fig. 28 and 29, the present embodiment can be divided into four modules, namely, an upper module 100 composed of the all-covering housing assembly 1, the spring roller shutter assembly 5, the first bracket 41 and the electric cross frame 81, two side modules 200 composed of the side rail assembly 2, the second bracket 42, the third bracket 43, the upper gear 83, the lower gear 84, the timing belt 85 and the sliding member 86, and a lower module 300 composed of the lower rail assembly 3 and the driving motor 82; when transporting and storing, the four modules can be completely detached to form a long-strip-shaped packaging structure, and the transportation and the storage are greatly facilitated.

The foregoing has described the principles, principal features, and advantages of the application. It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, which are merely illustrative of the principles of the application, but that various changes and modifications may be made without departing from the spirit and scope of the application, and these changes and modifications are intended to be within the scope of the application as claimed.
