[0036] Please refer to Figure 1 and Figure 2 , the foldable electronic device 1000 of the present application includes a housing 1, three pivoting modules 2 and a wire 3. The housing 1 is combined with the pivoting modules 2, and the wire 3 is clamped between the housing 1 and the pivoting modules 2. The structures of each component and the connection relationships between them will be described in detail below. Among them, some of the drawings are drawn with a first direction X, a second direction Y and a third direction Z that are perpendicular to each other.
[0037] The housing member 1 includes a housing body 11, three base portions 12, and a limiting portion 13. The housing body 11 extends along the first direction X, forming a long strip-shaped housing with a U-shaped cross-section, and having a corresponding first notch 111 and a second notch 112 on its opposite sides. The base portions 12 are formed on the housing body 11 at intervals from each other, and two of the base portions 12 are respectively located at opposite ends of the housing body 11, and the other base portion 12 is generally located at the middle of the housing body 11. The limiting portion 13 is adjacent to one of the base portions 12, and has two positioning posts 131 and a placement surface 132. The positioning posts 131 are generally cylindrical, and extend outward from the housing body 11 along the second direction Y at intervals from each other. The placement surface 132 is adjacent to the positioning posts 131 and extends along the first direction X and the third direction Z, and faces the pivoting module 2, and is located between the first notch 111 and the second notch 112 in the third direction Z.
[0038] Please refer to Figure 3 , the pivoting module 2 includes a central base 21, two wing members 22, two transmission members 23, two panel bodies 24, two water droplet plates 25, a torsion module 26, and a synchronization module 27. The central base 21 is fixed to the base portion 12 via, for example, screws. The wing members 22 are pivotally connected to opposite sides of the central base 21. The transmission members 23 connect the central base 21 and the torsion module 26. The panel bodies 24 are respectively pivotally connected to the wing members 22 and respectively connect the transmission members 23. The water droplet plates 25 are respectively connected to the wing members 22 and the panel bodies 24. The torsion module 26 is disposed in the housing body 11 and is adjacent to the limiting portion 13. The synchronization module 27 is slidably connected between the transmission members 23. The two water droplet plates 25 can be shared by multiple pivoting modules 2, or can also be used by a single pivoting module 2 respectively, that is, there will be six water droplet plates 25 for three pivoting modules 2, but the present application is not limited thereto.
[0039] The wire 3 is clamped between the pivoting module 2 and the housing member 1, and includes a wire body 31, a positioning portion 32, and two through holes 33. The wire body 31 is generally strip-shaped, substantially extends along the third direction Z, and is correspondingly disposed on the placement surface 132 and passes through the first notch 111 and the second notch 112. The wire body 31 can be a flat flexible cable or a round wire, and its width along the first direction X is smaller than the sizes of the first notch 111 and the second notch 112, but is not limited thereto. The positioning portion 32 is generally a rounded rectangular parallelepiped, protrudes and connects to one side of the wire body 31 along the first direction X, and is located inside the housing member 1. The positioning portion 32 can be an adhesive tape or a PCB board, but is not limited thereto. The through holes 33 are substantially formed through along the second direction Y in the positioning portion 32, and are respectively sleeved on the positioning posts 131. In this embodiment, the cross-section of the through holes 33 is circular, and the cross-sectional area of the through holes 33 is greater than or equal to the cross-sectional area of the positioning posts 131, whereby the wire 3 can act radially relative to the positioning posts 131.
[0040] Please refer to Figure 4 and Figure 5 simultaneously. The wire body 31 has a thickness H in the second direction Y, and this thickness H is less than the distance D between the pivot module 2 and the housing 1. Therefore, the wire body 31 can act axially (i.e., along the second direction Y) relative to the positioning post 131. For example, the wire body 31 can act between the position ( Figure 4 ) where it adheres to the placement surface 132 and the position ( Figure 5 ) where it adheres to the water droplet plate 25.
[0041] The distance D between the pivot module 2 and the housing 1 can be used as the maximum overall displacement of the wire 3 in the second direction Y. This maximum overall displacement is less than 10 mm, but the present application is not limited thereto. The maximum overall displacement of the wire 3 in the first direction X or the third direction Z can also be determined by the clearance fit (greater than 0 mm and less than 10 mm) between the through hole 33 and the positioning post 131, or the clearance fit (greater than 0 mm and less than 10 mm) between the wire body 31 and the first notch 111 and the second notch 112.
[0042] The above is described by taking two positioning posts 131 and two through holes 33 as examples, but the present application is not limited thereto, and it can also be a combination of a single positioning post 131 and a single through hole 33.
[0043] The flexible screen 4 is electrically connected to the wire 3 and is disposed on the wing member 22, the panel body 24, and the water droplet plate 25. Please refer to Figure 6 simultaneously. In the foldable electronic device 1000 of the present application, the pivot module 2 can be switched between an unfolded state ( Figure 4 and Figure 5 ) and a folded state ( Figure 6 ). When in the unfolded state, the flexible screen 4 is flattened. When in the folded state, the flexible screen 4 is flexed. When the pivot module 2 is switched between the unfolded state and the folded state, when the through hole 33 is not limited by the positioning post 131 (such as in the first direction X and the third direction Z), the wire body 31 is not limited by the first notch 111 and the second notch 112 of the housing body 11 (such as in the first direction X and the third direction Z), or the wire body 31 is not limited by the placement surface 132 and the pivot module 2 (such as in the second direction Y), the wire 3 can act integrally in any direction relative to the limiting portion 13 (i.e., axial, radial, or oblique actuation).
[0044] In summary, when the foldable electronic device of the present application is switched between the unfolded state and the folded state, since the wire can act integrally in any direction relative to the limiting portion, damage or breakage of the wire caused by stretching or extrusion during the folding process can be avoided.
