In one embodiment, the middle frame 21 and the bottom plate 22 may be a unitary structure.
The middle frame 21 may include a substrate 212 disposed opposite to the bottom plate 22 and a frame 211 surrounding the substrate 212 and connected to the bottom plate 22 and the substrate 212, respectively.
In particular, the substrate 212 is a plate-like structure, which may be rectangular, rounded rectangular, or the like, which may be formed of plastic, glass, ceramic, fiber composite, metal (e.g., stainless steel, aluminum, etc.), or other suitable material or combination of materials.

Referring to fig. 3, 4 and 5, fig. 5 is a schematic structural diagram of the folding assembly 30 of the embodiment shown in fig. 4 of the present application. The folding assembly 30 may include a first supporting plate 31 connected to the second housing 20 and used for supporting the display module 40, a second supporting plate 32 connected to the first housing 10 and used for supporting the display module 40, and a hinge module 30 connected to the first housing 10 and the second housing 20 and used for supporting the first supporting plate 31 and the second supporting plate 32.
It is understood that the terms "first pallet," "second pallet," and "pallet" may be used interchangeably, and that, for example, in some embodiments, "first pallet" may also be referred to as "second pallet" and "second pallet" may also be referred to as "first pallet".
Specifically, one side of the first supporting plate 31 close to the second casing 20 is pivotally connected to the middle frame 21, such as the frame 211, so that the first supporting plate 31 can rotate relative to the second casing 20 when the first casing 10 and the second casing 20 are folded.
In one embodiment, a side of the first supporting plate 31 near the second housing 20 may be pivotally connected to the middle frame 21, such as the base plate 212. The relative rotation of the first supporting plate 31 and the second housing 20 is achieved when the first housing 10 and the second housing 20 are folded.
One side of the first supporting plate 31 close to the first casing 10 is mounted on the rotating shaft module 30, and one side of the first supporting plate 31 far away from the rotating shaft module 30 is used for attaching the display module 40, so that the display module 40 is abducted when the first casing 10 and the second casing 20 are folded, and the display module 40 is supported when the first casing 10 and the second casing 20 are unfolded.
The first supporting plate 31 is provided with a second receiving groove 311 on a side close to the display module 40, that is, a side of the first supporting plate 31 attached to the display module 40, so as to communicate with the first receiving groove 2122, so as to arrange a circuit trace or a heat sink in the second receiving groove 311, so that the heat sink enters the second receiving space 201 through the second receiving groove 311, the first receiving groove 2122 and the through hole 2121.
One side of the second supporting plate 32 close to the first casing 10 is pivotally connected to the middle frame 11, such as the frame 111, so that the second supporting plate 32 can rotate relative to the first casing 10 when the first casing 10 and the second casing 20 are folded.
In one embodiment, a side of the second supporting plate 32 near the first casing 10 may be pivotally connected to the middle frame 11, such as the base plate 112. The relative rotation of the second palette 32 with the first housing 10 is achieved when the first housing 10 and the second housing 20 are folded.
One side that second layer board 32 is close to second casing 20 is carried on pivot module 30, and second layer board 32 is used for pasting on the one side of keeping away from pivot module 30 and establishes display module 40 for when first casing 10 and second casing 20 are folding to display module 40 abdicating, be used for when first casing 10 and second casing 20 expand to support display module 40.
The second receiving groove 321 is disposed on a side of the second supporting plate 32 close to the display module 40, that is, a side of the second supporting plate 32 attached to the display module 40, so as to communicate with the first receiving groove 1122, so as to arrange a circuit trace or a heat dissipation member in the second receiving groove 321, so that the heat dissipation member enters the first receiving space 101 through the second receiving groove 321, the first receiving groove 1122 and the through hole 1121.
Referring to fig. 2 again, the display module 40 may be a flexible display screen, which is a flexible display device made of flexible material. Which may be provided on the first case 10, the second case 20, and the folder assembly 30, for displaying information. The display module 40 can be an integrated structure, and of course, the display module 40 can also be a combination of a plurality of flexible display screens, wherein one of the flexible display screens is disposed on the folding assembly 30.
It can be understood that when the folding assembly 30 is folded, the first casing 10 and the second casing 20 are folded in half, and the display module 40 is also bent in half, and during long-term use, the display module 40 is creased due to the folding in half.
Please refer to fig. 6, which discloses a schematic structural diagram of the display module 40 in the embodiment of fig. 2. The display module 40 may include a display panel layer 41, a glue layer 42, and a flexible cover plate 43 stacked in sequence. Wherein the glue layer 42 bonds the display panel layer 41 and the flexible cover plate 43 together.
Because the layers above the display panel layer 41, such as the glue layer 42 and the flexible cover plate layer, are transparent, after the display module 40 is bent for many times, the residual deformation reaction of the material in the screen, such as the glue layer 42, generates creases on the surface of the display module 40, and further generates an optical distortion phenomenon.
The adhesive layer 42 is made of an organic polymer material, which is the most easily deformable material in the bending process of the display module 40 and is difficult to recover. The adhesive layer 42 has low viscosity and high elasticity at normal temperature, so that the creep amount of the adhesive layer is small when a user bends for a long time daily, and the adhesive layer is not suitable for being restored to be flat. The adhesive layer 42 has high viscosity, low elasticity and good fluidity at high temperature, and can be quickly restored to be flat.
The adhesive layer 42 is processed to rapidly weaken the unevenness of the surface of the display module 40, thereby facilitating the flatness of the screen.
