The cover 200 may be a transparent glass cover, so that a user can see the contents displayed on the display screen 100 through the cover 200. In some embodiments, the cover plate 200 may be a glass cover plate of sapphire material. It is understood that the electronic device 10 may not include the cover plate 200.

The middle frame 300 may have a thin plate-like or sheet-like structure, or may have a hollow frame structure. The middle frame 300 is used for providing a supporting function for the electronic components or functional assemblies in the electronic device 10, so as to mount the electronic components or functional assemblies in the electronic device 10 together. For example, functional components of the electronic device 10, such as a camera, a receiver, the display screen 100, the circuit board assembly 400, and the battery 500, may be mounted on the middle frame 300 for fixation. In some embodiments, the material of the middle frame 300 may include metal or plastic.

The circuit board assembly 400 may be mounted on the middle frame 300. The circuit board assembly 400 may be a motherboard of the electronic device 10.

The curved surface portion 120 is located on both sides of the planar portion 110 in the width direction, or the curved surface portion 120 extends outward from both side edges of the planar portion 110 in the width direction. It is understood that the "width direction" is a lateral direction of the display screen when the user normally uses the electronic device 10.

The planar portion 110 may have a planar structure, and the curved portion 120 may have a curved structure. The curved surface portion 120 is curved toward the non-display surface of the display screen 100, and the central angle corresponding to the curved surface portion 120 is greater than 90 °. That is, the cross section of the curved surface portion 120 is larger than a quarter of a circular arc.

It should be noted that the structure of the display screen 100 in the embodiment of the present application is not limited to this, and other embodiments are also possible. For example: the plane part 110 may not be a plane structure, but may form a curved surface structure similar to a curved surface screen lcd tv; the central angle of the curved surface portion 120 may also be no greater than 90 °, so that the display screen 100 forms a conventional "waterfall screen" rather than a "flip-up screen".

Referring to fig. 5 and fig. 6, fig. 5 is a schematic structural diagram of a middle frame of an electronic device according to an embodiment of the present disclosure, and fig. 6 is a partially enlarged view of a portion B in fig. 5. The middle frame 300 may include a body portion 310 and a mounting portion 320. The mounting portions 320 are located at both sides of the main body portion 310 in the width direction, or the mounting portions 320 are extended outward from both side edges of the main body portion 310 in the width direction. It is understood that the "width direction" is a lateral direction of the display screen when the user normally uses the electronic device 10.

The main body 310 may have a planar structure, and the mounting portion 320 may include a first branch 321 and a second branch 322. The first branch 321 is fixedly connected with the main body 310, in the thickness direction of the middle frame 300, the side surface of the first branch 321 facing the display screen 100 is lower than the side surface of the main body 310 parallel to the display screen 100, and a first step 331 is formed between the first branch 321 and the main body 310; the second portion 322 is fixedly connected to the first portion 321, a side of the second portion 322 facing the display screen 100 is lower than a side of the first portion 321 facing the display screen 100 in a thickness direction of the middle frame 300, and a second step 332 is formed between the second portion 322 and the first portion 321. That is, the main body 310 is thicker than the first division 321, the first division 321 is thicker than the second division 322, and the second division 322, the first division 321, and the main body 310 form a continuous step therebetween. It is understood that the side of the first section 321 facing the display screen 100 and the side of the second section 322 facing the display screen 100 may be parallel to the display screen 100 or not parallel to the display screen 100.

In the present embodiment, the structure of the frame 300 is not limited to this, and other embodiments are possible. For example, if the side surface of the first sub-portion 321 facing the display panel 100 and the side surface of the main body portion 310 parallel to the display panel 100 are parallel to each other in the thickness direction of the middle frame 300 and have the same height, the first step 331 does not exist between the first sub-portion 321 and the main body portion 310, or the first sub-portion 321 and the main body portion 310 are integrally formed, and only the second sub-portion 322 protrudes from the main body portion 310 in the width direction of the middle frame 300.

It should also be noted that the above-mentioned terms "first", "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features.

Referring to fig. 7 and 8 together, fig. 7 is a sectional view of the display panel and the middle frame of fig. 2 taken along a direction P1-P1, and fig. 8 is a partially enlarged view of a portion C of fig. 7. The electronic device 10 may also include a filler 700.

When the display screen 100 is mounted on the middle frame 300, the curved surface portion 120 of the display screen 100 covers the mounting portion 320 of the middle frame 300, the first step 331 and the second step 332 form a gap 710 between the display screen 100 and the middle frame 300, and the filling member 700 is disposed in the gap 710.

If the side of the first division 321 facing the display screen 100 is lower than the side of the main body 310 parallel to the display screen 100 in the thickness direction of the middle frame 300, the gap 710 includes a first step 331 and a second step 332, and the filling member 700 is substantially "L" -shaped; if the side surface of the first division 321 facing the display panel 100 and the side surface of the main body 310 parallel to the display panel 100 are parallel to each other in the thickness direction of the middle frame 300 and have the same height, the gap 710 includes only the second step 332, and the filling member 700 is substantially "I" shaped.

The filling member 700 has an inner surface and an outer surface, and the filling member 700 may be fixedly connected to the display screen 100 and the middle frame 300 by an adhesive or a glue layer 720. The outer surface of the filling member 700 is fixedly connected to the curved surface portion 120 of the display screen 100, and the inner surface of the filling member 700 is fixedly connected to the mounting portion 320 of the middle frame 300. The filling member 700 is fixedly connected to the curved surface portion 120 of the display screen 100 through a first adhesive tape or adhesive dispensing layer 721, and the filling member 700 is fixedly connected to the mounting portion 320 of the middle frame 300 through a second adhesive tape or adhesive dispensing layer 722.

The filling member 700 may be made of plastic. It should be noted that the material of the filling member 700 provided in the embodiment of the present application is not limited thereto, and other materials may be used. For example, the filling member 700 may be made of metal, such as magnesium alloy, stainless steel, etc. For another example, the filling member 700 may be made of glass. For another example, the filling member 700 may include a plastic part and a metal part, and the filling member 700 may be a structure in which an inner layer of metal and an outer layer of plastic are matched with each other to enhance the strength of the filling member 700.

Compared with the traditional screen assembling mode, when the curved screen with large curvature is assembled on the middle frame, the screen gum is easily scraped by the protruded middle frame. In the embodiment of the application, the installation space of the screen is reserved by arranging the steps through the installation part of the middle frame, and the gap generated by the steps is filled with the filling piece, so that the situation that the screen gum is scraped when the large-curvature curved screen is assembled on the middle frame can be avoided, and the screen assembly effect and the screen assembly efficiency are improved.
