Referring to fig. 1, fig. 1 is a first structural schematic diagram of an electronic device according to an embodiment of the present disclosure, where the electronic device 100 according to the embodiment of the present disclosure may include a display screen 110, a first casing 120, a second casing 130, a third casing 140, and a fingerprint key module 150.
The first housing 120 may include a first surface 121 and a second surface 122 disposed opposite to each other, the display screen 110 is located on the first surface 121 and is directly or indirectly connected to the first surface 121, and the second housing 130, the third housing 140 and the fingerprint key module 150 are located on the second surface 122. The second housing 130 is located between the first housing 120 and the third housing 140, the second housing 130 may be directly or indirectly connected to the first housing 120, the third housing 140 may also be directly or indirectly connected to the second housing 130, and of course, the third housing 140 may also be directly or indirectly connected to the first housing 120.
The second housing 130 may include a bottom plate 131 and a frame 132, the frame 132 may be directly or indirectly connected to the first housing 120, and the frame may be provided with a mounting hole 133 for the fingerprint case module 150 to collect user information. The bezel 132 may be disposed around the bottom plate 131, and the exemplary bezel 132 may be disposed around one, two, three, four or more sides of the bottom plate 131, so that the bezel 132, the bottom plate 131 and the second side 122 of the first casing 120 may form a receiving space 134, and at least a portion of the fingerprint key module 150 may be disposed in the receiving space 134.
It can be understood that the fingerprint key module 150 can be completely located in the accommodating space 134, that is, the fingerprint key module 150 does not pass through the mounting hole 133 and protrudes out of the electronic device 100, and at this time, the user finger can be pressed inward from the mounting hole 133 to contact the fingerprint key module 150 to collect fingerprint information. Certainly, a part of the fingerprint key module 150 may be located in the accommodating space 134, and another part of the fingerprint key module passes through the mounting hole 133 and protrudes out of the electronic device 100, at this time, a finger of a user directly touches the fingerprint key module 150 outside the electronic device 100 to collect fingerprint information.
Wherein, fingerprint key module 150 can include fingerprint chip subassembly 151 and button subassembly 152, and fingerprint chip subassembly 151 can be used for receiving user's fingerprint information, and fingerprint chip subassembly 151 can pass the mounting hole 133 of second casing 130 and protrusion in electronic equipment 100's outside, and fingerprint chip subassembly 151 also can be located the mounting hole 133 of second casing 130 and not protrusion in electronic equipment 100's outside.

In the electronic device 100 of the embodiment of the application, the fingerprint chip assembly 151 and the key assembly 152 are integrated into one fingerprint key module 150, and the space occupied by one fingerprint key module 150 is small, so that the space utilization rate in the electronic device 100 can be improved; meanwhile, only one mounting hole 133 needs to be arranged on the frame 132 of the second housing 130, so that the waterproof and dustproof effects of the housing can be improved. Moreover, since the display screen 110 is disposed on the first housing 120 and the fingerprint key module 150 is disposed on the second housing 130, the display screen 110 is not required to be disposed on the second housing 130, so that the width of the frame 132 of the second housing 130 is not required to be reduced due to the reduction of the size of the "black frame" of the second housing 130. The width of the frame 132 of the second housing 130 according to the embodiment of the present disclosure may be larger. Moreover, the second housing 130 is connected to the first housing 120, the second housing 130 may cover the first housing 120, and a width of the frame 132 of the second housing 130 may be greater than a thickness of the first housing 120, so that the frame 132 of the second housing 130 according to the embodiment of the present disclosure may also have a greater width. Furthermore, when the width of the frame 132 of the second housing 130 of the embodiment of the present application is large, the size of the mounting hole 133 formed on the second housing 130 may also be large, and the mounting hole 133 may even be opened into the boundary transition area between the frame 132 and the bottom plate 131, so that the size of the fingerprint key module 150 may also be large, and further, the fingerprint collection area of the fingerprint key module 150 of the embodiment of the present application is large, and the sensitivity of the fingerprint key module 150 may be improved.

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 opposite to the other side where the mounting hole 133 is formed forms a second side space area 125, and functional components such as the battery 170 and the main 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.

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 and the bezel 132 of the second housing 130 and the fingerprint key module 150, 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.

The inner surface 141 refers to a side surface that is not visible to a user, that is, a side surface of the third housing 140 adjacent to the second housing 130. Here, the heat sink 190 may be disposed on a side surface of the third housing 140 close to the second housing 130, that is, an inner surface 141 of the third housing 140. When the battery 170 protrudes from the notch 135 of the second housing 130 and is connected to the third housing 140, the battery 170 may be connected to and closely abutted against the heat sink 190, and thus, heat generated by the battery 170 during operation may be transferred to the air through the heat sink 190 to dissipate the heat.
It is understood that the heat sink 190 may cover the battery 170, that is, a larger heat sink 190 may be disposed on the third housing 140 to improve the heat dissipation efficiency of the heat sink 190.

Furthermore, the heat dissipation member 190 may additionally occupy the thickness space of the electronic device 100, without increasing the thickness of the electronic device 100.
It can be understood that the third housing 140 may be made of plastic or resin, and the structure of the groove 143 may be formed once by the third housing 140 during injection molding, so that the third housing 140 does not need to be formed again by milling, boring, and the like, and the production process of the third housing 140 may be simplified.
The first housing 120, the second housing 130, and the third housing 140 of the electronic device 100 according to the embodiment of the present application are described above, and the structure of the fingerprint key module 150 according to the embodiment of the present application will be described in detail below with reference to the drawings.

Another part of the fingerprint chip assembly 151 passes through the mounting hole 133 and is located in the receiving space 134 formed by the bottom plate 131 of the second casing 130, the rim 132 and the second surface 122 of the first casing 120. For example, the fingerprint chip assembly 151 of the embodiment of the present application may include a fingerprint sensor 1511 and a fingerprint chip 1512, and the fingerprint sensor 1511 is exposed outside the electronic device 100 through the mounting hole 133 on the bezel 132 so as to receive fingerprint information of a user.

Illustratively, the key assembly 152 may include a key 1521 and an elastic member 1522, and the key 1521 may be electrically connected to the second circuit board 154, so that the second circuit board 154 may receive control information of the key assembly 152.
The elastic member 1522 may be located between the key 1521 and the fingerprint chip assembly 151, that is, one end of the elastic member 1522 may abut against the key 1521, and the other end of the elastic member 1522 may be connected to the fingerprint chip assembly 151.
