The embodiments in the present application may be combined as appropriate.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device 100 according to an embodiment of the present disclosure. The electronic device 100 may be a mobile phone, a tablet, an e-reader, a computer, an electronic display screen, or the like. The present application takes a mobile phone as an example for illustration. In this embodiment, the length direction of the electronic device 100 is defined as the Z-axis direction. The width direction of the electronic device 100 is defined as the X-axis direction. The thickness direction of the electronic device 100 is defined as the Y-axis direction. Wherein the direction indicated by the arrow is the forward direction.

Referring to fig. 1, the electronic device 100 may include a housing 10 and keys 20 mounted on the housing 10. in general, the keys 20 mounted on the housing 10 include, but are not limited to, a power key and a volume key. When the electronic device 100 is used, the screen 2 can be turned on or off and the device can be turned on or off by pressing the power key; the volume can be adjusted by pressing a volume key; screen capture, photographing and the like can be realized by pressing the power key and the volume key. The key 20 may be a time delay switch, a touch key, a micro switch, a photoelectric switch, a membrane key, etc.

Referring to fig. 2 and 3, the embodiment of the present application will be described by taking the middle frame 101 of the housing 10 as an example, in which the key 20 is installed. The housing 10 of the electronic device 100 includes a middle frame 101 and a rear cover 102 connected to each other. In the embodiment of the present application, the key 20 includes a pressing member 201 and a switch member 202. The pressing member 201 is for providing a pressing position and generating a force to the switching member 202 when pressed. The switching element 202 is an electronic component that can open a circuit, interrupt a current, or allow a current to flow to other circuits.

The application researcher discovers that when the pressing piece of the key is installed in the through hole on the middle frame from the outer side of the middle frame (wherein, the outer side of the middle frame refers to the outer side of the peripheral edge of the middle frame, in the electronic equipment, the outer side of the middle frame is also the outer side of the electronic equipment), a support used for fixing the pressing piece needs to be arranged on the middle frame, so that at least one through hole communicated with the through hole needs to be additionally arranged on the side wall of the middle frame to form an installation support, so that more holes are formed in the middle frame, the waterproof width of the middle frame is reduced, the structural strength of the middle frame is reduced, and meanwhile, the structure on the middle frame is more, the assembly working hours are prolonged, and the material cost and the assembly cost are increased.

The embodiment of the application provides an electronic device 100 which enables a key to have good waterproofness and good installation stability. As shown in fig. 3, fig. 3 is an exploded schematic view of a middle frame, a pressing member, a switch member, and a sealing member of an electronic device according to an embodiment of the present disclosure. The electronic apparatus 100 includes a middle frame 101, a pressing member 201, a switching member 202, and a sealing member 30.

Referring to fig. 2 and 4, the middle frame 101 may include an upper cover plate 111, a left side plate 113, a lower cover plate 112, and a right side plate 114, which are sequentially connected end to end. The upper cover 111, the left side plate 113, the lower cover 112, and the right side plate 114 surround a space forming the middle frame inner side 110. The space inside the middle frame 110 may be a space for mounting a circuit board and a battery in the electronic device 100, and the outside of the corresponding middle frame 101 may be understood as an external environment outside the electronic device 100. In the embodiment of the present application, the key 20 is mounted on the right side plate 114 of the middle frame 101 as an example. The following description of the middle frame 101 can be properly understood as a right side plate 114 of the middle frame 101. In the embodiment of the present application, the length direction of the middle frame 101 is along the Z-axis direction, the width direction of the middle frame 101 is along the Y-axis direction, and the thickness direction of the middle frame 101 is along the X-axis direction. Referring to fig. 4 and 5, the middle frame 101 has a middle frame inner wall 115 and a middle frame outer wall 116 opposite to each other, and a middle frame side wall 117 connected between the middle frame inner wall 115 and the middle frame outer wall 116, wherein the middle frame inner wall 115 can be understood as an end surface of the right side plate 114 close to the middle frame inner side 110. In other words, the inner side 110 of the middle frame is the side of the inner wall 115 of the middle frame. The middle frame outer wall 116 can be understood as an end surface of the right side plate 114 of the middle frame 101 located outside the middle frame 101. The inner wall 115 of the middle frame is used for forming the appearance surface of the electronic device 100.

As shown in fig. 6, the middle frame 101 is provided with a stepped hole 118 penetrating through the middle frame inner wall 115 and the middle frame outer wall 116. Specifically, the first opening 1181 of the stepped hole 118 is located on the inner wall 115 of the middle frame, and the second opening 1182 of the stepped hole 118 is located on the outer wall 116 of the middle frame. An inner wall 1183 of stepped bore 118 includes a first stepped surface 1180 facing toward middle bezel inner side 110. In other words, the hole with the smaller diameter in the stepped hole 118 is close to the middle frame outer wall 116, the hole with the larger diameter in the stepped hole 118 is close to the middle frame inner wall 115, and the connecting surface of the inner walls of the holes with different diameters forms the first stepped surface 1180.

When the pressing piece 201 is assembled, the pressing piece 201 is installed along the direction of the middle frame inner wall 115 pointing to the middle frame outer wall 116, one end of the pressing piece 201 (i.e. the end face which enters the step hole 118 first when the pressing piece is installed) passes through the step hole 118, passes through the middle frame outer wall 116, and is partially exposed out of the middle frame outer wall 116, and in other embodiments, one end of the pressing piece 201 may be flush with the middle frame outer wall 116. When the pressing piece 201 is assembled, one end of the pressing piece 201 away from the middle frame outer wall 116 abuts against the first step surface 1180. It can be understood that the first step surface 1180 has a first supporting force to the pressing member 201 toward the inner frame wall 115, so that the pressing member 201 can be fixed in the step hole 118 by the first step surface 1180. The other end of the pressing member 201 (i.e., the end surface of the pressing member 201 that enters the stepped hole 118 after being placed on the switch member 202) elastically abuts against the switch member 202. It can be understood that the switch member 202 is located on one side of the pressing member 201 close to the inner wall 115 of the middle frame, and abuts against the pressing member 201.

Optionally, as shown in fig. 2 and fig. 6, the switch element 202 is at least partially located in the stepped hole 118, at this time, the pressing element 201 is located in the stepped hole 118, and the pressing element 201 and the switch element 202 abut against each other in the stepped hole 118. In this embodiment, the switch 202 and the pressing member 201 are accommodated in the middle frame 101, so that the space inside the middle frame 110 (i.e. the electronic device 100 is used for accommodating a battery, a circuit board, etc.) is saved, and the performance of the electronic device 100 is improved and the function diversification is promoted.

In another embodiment, the switch member 202 may be located outside the stepped hole 118, that is, the switch member 202 is located inside the middle frame 110, and at this time, the other end of the pressing member 201 extends out of the inner wall 115 of the middle frame, and the switch member 202 abuts against the pressing member 201 inside the middle frame 110. In this embodiment, the thickness of the middle frame 101 can be designed to be small, which is advantageous for downsizing the electronic apparatus 100.

As shown in fig. 6, the sealing member 30 is supported on a side of the opening and closing member 202 facing away from the pressing member 201. In other words, the switch 202 is interposed between the sealing member 30 and the pressing member 201, the sealing member 30 applies a supporting force to the switch 202, the supporting force is transmitted to the pressing member 201 via the switch 202, and thus, a first supporting force (first step surface 1180 acting) toward the inner wall 115 of the middle frame and a second supporting force (sealing member 30 acting) toward the outer wall 116 of the middle frame are applied to the pressing member 201, and the pressing member 201 is fixed to the step hole 118 by the first supporting force and the second supporting force in opposite directions of application. As can be appreciated, the sealing member 30 applies a second supporting force to the pressing member 201 toward the middle frame outer wall 116, so that the pressing member 201 abuts against the first step surface 1180 and the sealing member 30, further improving the stability of the fixing of the pressing member 201 in the step hole 118.

The sealing member 30 is coupled to the middle frame 101 and seals the stepped hole 118. In some embodiments, when the sealing member 30 seals the stepped bore 118, a gap is formed between the sealing member 30 and the inner wall 1183 of the stepped bore 118, and the gap can be filled with a sealing compound for connecting the switch member 202 and the inner side 110 of the middle frame. In other possible embodiments, the sealing member 30 directly engages the inner wall 1183 of the stepped bore 118 to seal the stepped bore 118.

Through the arrangement of the through stepped hole 118 between the inner wall 115 of the middle frame and the outer wall 116 of the middle frame, and the first stepped surface 1180 faces towards the inner side 110 of the middle frame, when the pressing piece 201 is installed, an assembly mode from the inner wall 115 of the middle frame to the outer wall 116 of the middle frame is adopted, and the pressing piece 201 is not easy to touch the appearance surface of the middle frame 101 in an assembly mode from inside to outside, so that the attractiveness of the middle frame 101 can be ensured; when the pressing piece 201 is assembled, the pressing piece 201 is fixed under the abutting force generated by the first step surface 1180 of the step hole 118 and the sealing element 30, the pressing piece 201 is fixed simply, the use of fixing brackets on the middle frame 101 is reduced, and therefore the waterproofness of the middle frame 101 can be improved and the assembly cost can be reduced; in addition, the sealing member 30 is arranged to seal the inner wall 1183 of the connecting stepped hole 118, so that the waterproof performance of the middle frame 101 is further improved.

Alternatively, as shown in fig. 8, the sealing member 30 is partially located in the stepped hole 118 and partially located on the inner side 110 of the middle frame, the outer peripheral wall 301 of the sealing member 30 located in the stepped hole 118 is connected to the inner wall 1183 of the stepped hole 118, and the outer peripheral wall 301 of the sealing member 30 located outside the stepped hole 118 is connected to the inner wall 115 of the middle frame. It is understood that the outer peripheral wall 301 of the sealing member 30 may include a first end surface 310a, a peripheral side surface 311a and a second end surface 312a connected in sequence, wherein the first end surface 310a abuts against the switch member 202 located in the stepped hole 118, the peripheral side surface 311a adjacent to the first end surface 310a is connected to the inner wall 1183 of the stepped hole 118, and the second end surface 312a connected to the peripheral side surface 311a is connected to the inner frame wall 115. In this embodiment, both the pressing member 201 and the switch 202 are located in the stepped hole 118, and therefore, the contact reliability of both the pressing member 201 and the switch 202 and the waterproof performance of the middle frame 101 can be improved.

In other possible embodiments, referring to fig. 2 and 9, the sealing member 30 may be located outside the stepped hole 118 and on the inner side 110 of the middle frame, and the sealing member 30 completely covers the first opening 1181 of the stepped hole 118, and it can be understood that the sealing member 30 has a first end surface 310b, the first end surface 310b corresponds to the opening of the stepped hole 118, the switch member 202 abuts against the middle portion of the first end surface 310b, and the edge of the first end surface 310b is connected to and attached to the inner wall 115 of the middle frame. In this embodiment, the thickness of the middle frame 101 can be designed to be small, which is advantageous for miniaturization of the electronic apparatus 100.

Referring to fig. 6 and 10, the outer peripheral wall 301 of the sealing member 30 may be connected to the inner wall 1183 of the stepped hole 118 and the inner wall 115 of the middle frame by bonding or welding.
