[0040] It should be noted that the signal transmission element of the substrate 11 or the function board 21 can also be set as an NFC chip to achieve the function of interacting with the mobile phone without setting the power supply element 25 in the substrate 11 or the function board 21. In other embodiments, the substrate 11 and the function board 21 are coupled through a data line or a contact point to achieve the control of the function board 21 by the button 111.
[0041] like Figure 2 , Figure 3 and Figure 4 In the second embodiment, the substrate 11 of this embodiment adheres to a part of the back of the mobile device, and the functional board 21 adheres to another part of the back of the mobile device, that is, the substrate 11 and the functional board 21 together constitute a protective shell adhered to the back of the mobile device, wherein the substrate 11 adheres to a part of the back and side of the mobile phone near the camera hole 112, and the functional board 21 adheres to a part of the back and side of the mobile phone near the charging port.
[0042] It should be supplemented that the protective shell includes an upper protective shell 1 and a lower protective shell 2. The upper protective shell 1 is arranged close to the substrate 11, and the lower protective shell 2 is arranged close to the function board 21. A first fixing component 13 is arranged on the side of the upper protective shell 1 close to the function board 21, and a second fixing component 22 detachably assembled with the first fixing component 13 is arranged on the lower protective shell 2.

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.

[0047] Among them, an installation area 14 is opened on the substrate 11 for the function board 21 to be detachably installed. The installation area 14 is specifically an embedding groove opened on the side of the substrate 11 away from the mobile phone. The shape of the embedding groove is adapted to the function board 21. A first fixing member 13 is arranged on the side of the embedding groove close to the charging port of the mobile phone, and a second fixing member 22 is correspondingly arranged on the function board 21; after the function board 21 is embedded in the embedding groove, the first fixing member 13 clamps the second fixing member 22 to realize the fixed assembly of the function board 21.
[0048] It should be noted that, in the present embodiment, the first fixing member 13 is a snap-in plate, and the second fixing member 22 is a groove.
