When the two moving plates 5 are in the folded position, the folding limiting structure can limit the folding of the moving plate 5, prevent over-folding from causing damage or malfunction of the device, and ensure the stability and safety of the device in the folded state. When the two moving plates 5 are in the unfolded position, the unfolding limiting structure between the moving plate 5 and the rotating driving force arm 41 ensures that the moving plate 5 remains flat during unfolding of the device, avoids inconvenience or visual unattractiveness caused by unevenness, and improves user experience.

[0032] It can be understood that the hinge assembly of the foldable 3C device realizes smooth folding and unfolding of the device through the precisely designed moving plates 5 and moving pieces 2. The folding limiting structure and the unfolding limiting structure further improve the stability of the device in different states and the user experience.

[0033] In a specific embodiment of the present application, when the two moving plates 5 are in the unfolded position, the two moving plates 5 are in the same plane.

[0034] It can be understood that the two moving plates 5 in the unfolded position in the embodiment are in the same plane, which ensures the flatness of the device and helps to improve the user experience.

[0035] In an embodiment of the present application, the two motion plates 5 form a conical space 6 when they are in the folded position.

[0036] It can be understood that the two motion plates 5 form a conical space 6 when they are in the folded position in the embodiment, which provides space compensation for screen folding and avoids the screen from being squeezed or stretched during the whole bending process.

[0039] It can be understood that the flattening limiting structure in the embodiment is used to limit or guide the movement of the motion plate 5, ensuring the movement of the motion plate 5 in a specific direction while preventing it from deviating from the predetermined path. The flattening clamping groove 71 is used to accommodate and fix the flattening clamping part 72, thereby realizing the limiting function. The flattening clamping part 72 can be inserted into the flattening clamping groove 71 to realize the connection and limiting of the movable piece 2 and the motion plate 5.

[0040] It can be understood that the flattening limiting structure realizes effective control of the relative movement of the two components by arranging the flattening clamping groove 71 and the flattening clamping part 72 on the motion plate 5 and the movable piece 2 respectively, which not only simplifies the assembly process, but also improves the stability and reliability of the equipment.

[0044] Specifically, in this embodiment, one end of the folding limiting member 51 is connected to the moving plate 5. When the two moving plates 5 are in the folded position, the other end of the folding limiting member 51 connected to the moving plate 5 passes through the gap connection 23 of the movable member 2, so that the moving plate 5 is in contact with the corresponding connected movable member 2, and there is an included angle between the two moving plates 5.
