portions

21 and 22. The mounting block 25 has a strip-shaped receiving groove 25a at a side thereof remote from the battery 40. The flexible circuit board 26 is located in the strip-shaped receiving groove 25 a. In the embodiment of the present disclosure, the strip-shaped receiving groove 25a extends from the side of the mounting block 25 close to the first circuit board 30 to the first receiving portion 21, so that the sensing piece 501 can be close to the flip 50. Fig. 10 is a schematic structural diagram of a flip cover according to an embodiment of the present disclosure. As shown in fig. 10, the folder 50 includes an outer layer 51 and an inner layer 52, and the outer layer 51 and the inner layer 52 are coupled by a snap.
