[0031] It should be supplemented that the second signal transmission module 220 in the function board 200 and the first signal transmission module 120 in the substrate 100 are indirectly controlled. For example, the command information is sent to the first control circuit board 110 in the substrate 100 through the button 11, and the first control circuit board 110 in the substrate 100 sends the command information to the mobile device 300 through the first signal transmission module 120 in the substrate 100.

An extended screen is covered on the notch of the open slot. The extended screen is coupled to the second control circuit board 210, and is connected to the mobile device 300 by signal through the second signal transmission module 220. The mobile device 300 sends the image signal to the second control circuit board 210 through the second signal transmission module 220, and the second control circuit board 210 presents the image information on the extended screen, so that the extended screen can interact with the mobile device 300.

Of course, it is also possible to have other functional modules 240 when having the charging function, that is, multiple functional modules 240 are coupled to the second control circuit board 210.

[0037] Combined with Figure 2 And attached Figure 7 When the functional module 240 is a wireless charging coil 241, a positioning structure needs to be provided near the wireless charging coil 241 for fixing and assembling the external wireless charging device and the wireless charging coil 241.

After the first fixing component 13 and the second fixing component 22 are assembled, the upper protective shell 1 and the lower protective shell 2 can be fixed, and the fixed upper protective shell 1 and the lower protective shell 2 cover the side of the mobile phone.

[0042] In this embodiment, the first fixing member 13 is a snap-in groove with a first screw hole, and the second fixing member 22 is a snap-in block with a second screw hole corresponding to the first screw hole. When the snap-in block is inserted into the snap-in groove, the first screw hole and the second screw hole are penetrated by screws to realize the snap-in assembly and screw positioning of the first fixing member 13 and the second fixing member 22, so as to provide fixed assembly of the upper protective shell 1 and the lower protective shell 2.

[0043] The clamping slot is provided on the inner side wall of the substrate 100, i.e., the side close to the side of the mobile phone, and the first screw hole is provided at the bottom of the clamping slot, and the first screw hole connects the inner side wall and the outer side wall of the substrate 100; the clamping block is also provided on the outer side wall of the functional board 200, and the second screw hole is provided corresponding to the first screw hole. In this embodiment, there are two sets of clamping slots and clamping blocks, which are respectively provided on both sides of the upper protective shell 1 and the lower protective shell 2.

[0044] It should be noted that when the snap-in blocks and snap-in grooves of the upper protective shell 1 and the lower protective shell 2 are assembled, a slide groove 4 is provided on the inner side of the upper protective shell 1 and the lower protective shell 2, and a slide rail 3 is provided on the outer side of the functional board 200 and the base plate 100.
