The locking part 155 passes through the second arc-shaped slide rail C2 and the second through hole TH2 of the second end E2, so as to clamp the second bracket 120 and the third bracket 130 between the head 154 and the fourth locking part 152.

Referring to fig. 3A to fig. 4C, the foldable electronic device 50 further includes a housing assembly 80. The housing assembly 80 includes a first housing 81 and a second housing 82. The first housing 81 covers the second bracket 120 and is connected to the second body 70, the second housing 82 covers and is connected to the third bracket 130, and the first housing 81 is adapted to cover the second housing 82.

In an embodiment, as shown in fig. 1A and fig. 1B, the first body 60 has a notch 61, so that when the second body 70 is unfolded relative to the first body 60, the housing assembly 80 extends into the accommodating area AP of the first body 60 through the notch 61, so that the housing assembly 80 can be hidden when the second body 70 is unfolded, and the foldable electronic device 50 presents a simple and clear appearance at the second position P2 (fig. 1C), thereby improving the overall appearance quality of the foldable electronic device 50.

In one embodiment, as shown in fig. 2A to 4C, when the second body 70 is unfolded relative to the first body 60 and rotates from the first position P1 to the second position P2 through the intermediate position PC, the second torque assembly 150 is configured to have a torque smaller than that of the first torque assembly 140, so that the rotation of the second body 70 sequentially drives the second bracket 120 to rotate relative to the third bracket 130 along the virtual axis AX and the third bracket 130 to rotate relative to the first bracket 110 along the virtual axis AX.

That is, as shown in fig. 3A and 3B, the rotation of the second body 70 first drives the second frame 120 to rotate relative to the third frame 130 along the virtual axis AX, so that the second torsion component 150 slides along the second arc-shaped slide rail C2, and the first housing 81 firstly covers the second housing 82 until the second torsion component 150 cannot slide along the second arc-shaped slide rail C2 (i.e., is located at the middle position PC).

At this time, as shown in fig. 4B and 4C, the third bracket 130 rotates relative to the first bracket 110 along the virtual axis AX, so that the first torsion element 140 slides along the first arc-shaped slide rail C1, and the first housing 81 covering the second housing 82 and the second housing 82 extend into the first body 60 together until the second inclined surface SC2 is attached to the first inclined surface SC1 (i.e., located at the second position P2).

In this way, through the two-stage rotation of the second bracket 120 of the hinge module 100 relative to the third bracket 130 along the virtual axis AX and the third bracket 130 relative to the first bracket 110 along the virtual axis AX, the volume required by the hinge module 100 during the rotation operation can be reduced, the number of parts and the cost of the hinge module 100 can be relatively simplified, and the accommodating area AP required by the hinge module 100 for the first body 60 can be greatly reduced, so as to reduce the overall thickness of the first body 60.

Moreover, since the housing assembly 80 is a two-piece first housing 81 and second housing 82, the first housing 81 connected to the second body 70 can cover the second housing 82 first and then extend into the first body 60 together with the second housing 82, and the housing assembly 80 covering the hinge module 100 has no gap at the connection with the first body 60 and the second body 70, thereby not only preventing external substances from entering the first body 60, the second body 70 and the housing assembly 80 to damage the internal structure, but also preventing the hinge module 100 from being exposed outside the first body 60, the second body 70 and the housing assembly 80, and improving the overall appearance of the foldable electronic device 50.

To sum up, in the foldable electronic device of the present invention, the hinge module is connected between the first body and the second body, and the virtual axis is located between the one side of the first inclined plane and the one side of the second inclined plane that are closest to each other, so that when the second body is unfolded to any angle relative to the first body, the size of the gap between the first body and the second body is consistent and the appearance of the compact and beautiful appearance is presented, thereby improving the overall appearance texture of the foldable electronic device.
