The electronic device 10 includes but is not limited to the following structures: a housing 100, a flexible display screen 200, a dustproof member 300, and a baffle 400.

[0026] Specifically, the flexible display screen 200 is connected to the housing 100 and can be folded with the relative rotation of the housing 100 ( Figure 2 mid state) or flattened ( Figure 1 In the embodiment, the dustproof member 300 and the baffle 400 are respectively two (groups), and are respectively arranged on opposite sides of the bending area of ​​the flexible display screen 200, so as to prevent dust and physically protect the opposite sides of the bending area of ​​the flexible display screen 200 from the side positions of the flexible display screen 200. The bending area of ​​the flexible display screen 200 mentioned here refers to the middle area of ​​the flexible display screen 200, which is the area where bending deformation occurs during the folding process.

[0027] Optionally, see Figure 3 The housing 100 in this embodiment includes a first housing 110, a second housing 120 and a shaft assembly 130; the first housing 110 and the second housing 120 are respectively connected to the shaft assembly 130, and the first housing 110 and the second housing 120 can rotate relative to the shaft assembly 130; wherein, the detailed structure of the shaft assembly (which may include a gear set and a rotating shaft, etc.) is within the scope of understanding of those skilled in the art, and will not be repeated here. The flexible display screen 200 is respectively connected to the first housing 110 and the second housing 120, and can be folded or flattened with the relative rotation of the first housing 110 and the second housing 120.

[0029] Optionally, see Figure 3 , Figure 4 and Figure 5 The baffle 400 is disposed on opposite sides of the bending area of ​​the flexible display screen 200, and a gap 101 is provided between the baffle 400 and the edge of the bending area of ​​the flexible display screen 200. The dustproof member 300 is specifically used to prevent dust from entering the gap 101 between the edge of the bending area of ​​the flexible display screen 200 and the baffle 400. The baffle 400 is used to physically protect the flexible display screen 200 at the edge of the bending area of ​​the flexible display screen 200, so that the entire electronic device meets the drop reliability requirements. Please refer to Figure 6 , Figure 6 It is a schematic diagram of the partial structural disassembly of the baffle and the shaft assembly, wherein the baffle 400 can be fixedly connected to the end of the protective cover 131 of the shaft assembly 130, and the end of the protective cover 131 can be provided with a mounting groove 1310, and one end of the baffle 400 is fixed in the mounting groove 1310 (specifically, it can be adhesive, welding, etc., which is not specifically limited here).

[0030] Optionally, see Figure 5 , the width of the gap 101 is 0.05mm to 0.5mm. Optionally, in consideration of the difficulty of assembly and the prevention of scratching the edge of the bending area of ​​the flexible display screen 200 (when the folded state falls, the baffle 400 squeezes the flexible display screen 200 and causes the screen to fail), the width of the gap 101 is generally about 0.4mm. However, in order to make the gap 101 smaller, the baffle 400 in the embodiment of the present application can be made into a disassembled structure. Please refer to Figure 7 , Figure 7 4 is a schematic diagram of the structure of an embodiment of the baffle of the present application, wherein the baffle 400 in this embodiment may include a connecting portion 410 and a shielding portion 420; the connecting portion 410 is used to connect with the housing 100 (please continue to refer to Figure 6 Specifically, it can be connected to the protective cover 131 of the hinge assembly 130, and the shielding portion 420 is set corresponding to the edge of the bending area of ​​the flexible display screen 200, and a gap 101 is formed between the edge of the bending area of ​​the flexible display screen.

At the same time, the stress on the flexible display 200 is also smaller when the whole machine falls.

[0032] Optionally, see Figure 5 In order to take into account both the reliable protection of the bezel 400 for the flexible display screen 200 and the aesthetics of the entire electronic device, in the thickness direction of the electronic device in a completely flattened state, the end surface 421 of the shielding portion 420 away from the connecting portion 410 is slightly higher than the surface 201 of the flexible display screen 200 used for display and the edges of the first shell 110 and the second shell 120 (only the edge 111 of the first shell 110 is shown in the figure). Specifically, it can be slightly higher than 0.2mm to 3mm. Those skilled in the art can set it by themselves on the premise of comprehensively considering the reliable protection of the bezel 400 for the flexible display screen 200 and the aesthetics of the entire electronic device, and it is not specifically limited here.
