Moreover, the blocking member 123 may be directly or indirectly connected to the second surface 122 of the first casing 120, and the blocking member 123 may extend toward the second casing 130, so that the blocking member 123 protrudes from the second surface 122 of the first casing 120 and is located between the first casing 120 and the bottom plate.

It can be understood that, as shown in fig. 3, the blocking member 123 may divide the second surface 122 of the first casing 120 into two spatial regions, the blocking member 123 and the region where the frame 132 with the mounting hole 133 is located may form a first side spatial region 124, and the fingerprint key module 150 may be located in the first side spatial region 124. The area of the blocking member 123 where the frame 132 is located on the other side opposite to the frame 132 where the mounting hole 133 is opened forms a second side space area 125, and functional components such as the battery 170 and the circuit board 160 can be located in the second side space area 125.

It is understood that the blocking member 123 may be integrally formed with the first housing 120. The stopper 123 may also be a separate component from the first housing 120 and be connected to the second face 122 of the first housing 120 by welding, riveting, screwing, or the like. Of course, the blocking member 123 may also be integrally formed with a plate, and the plate may be connected to the second surface 122 of the first casing 120 and attached to the second surface 122, so as to indirectly connect the blocking member 123 and the second surface 122.

To further improve the waterproof and dustproof performance of the electronic device 100, please refer to fig. 4, and fig. 4 is a third schematic structural diagram of the electronic device according to the embodiment of the present disclosure. The electronic device 100 of the embodiment of the present application may further include a waterproof member 180.

The waterproof member 180 may be positioned between the second housing 130 and the first housing 120. For example, at least one portion of the waterproof member 180 may be located between the bottom plate 131, the rim 132 and the fingerprint key module 150 of the second housing 130, and at least another portion of the waterproof member 180 may be located between the second side 122 of the first housing 120 and the fingerprint key module 150. At this moment, waterproof 180 can form a sealed waterproof area, can all seal up the gap between fingerprint button module 150 and first casing 120, the second casing 130, improves fingerprint button module 150's leakproofness.

The outer surface 142 refers to a side of the third housing 140 away from the second housing 130.

It is understood that the bottom plate 131 of the second housing 130 may not have a notch corresponding to the circuit board 160, so that the circuit board 160 is located between the bottom plate 131 and the first housing 120, and the bottom plate 131 may protect the circuit board 160, and may prevent the circuit board 160 from being disconnected from the first housing 120 when the electronic device 100 is impacted by an external force.
