Detailed Description

Fig. 1 is a schematic view of a foldable electronic device according to an embodiment of the present invention. Fig. 2 is an exploded view of a portion of the foldable electronic device of fig. 1 in another state. Fig. 3 is a partial schematic diagram of the foldable electronic device of fig. 1 from another view angle. Referring to fig. 1 to fig. 3, in the present embodiment, the foldable electronic device 100 is, for example, a notebook computer capable of providing multi-screen display, and includes a first screen 110, a worm 130, a moving member 140, a rotating shaft 170, at least one second screen 120 (here, two second screens 120 are taken as an example), and at least one link 150 (here, a plurality of links 150 are taken as an example in combination with the number of the second screens 120).

The worm 130 is rotatably provided to the first screen 110. The moving member 140 is coupled to the worm 130 such that the moving member 140 moves along the worm 130 when the worm 130 rotates. The second screen 120 is movably disposed on the first screen 110. The connecting rod 150 is pivotally connected between the moving member 140 and the second screen 120, so that when the moving member 140 moves along the worm 130, the connecting rod 150 drives the second screen 120 to move away from or close to the worm 130, and the second screen 120 moves out of the first screen 110 or is accommodated behind the first screen 110.

In the embodiment, since the second screen 120 is disposed on the first screen 110, and the first screen 110 is connected to the body 160 through the rotating shaft 170, the first screen 110 can rotate relative to the body 160 through the rotating shaft 170 about the axis X1, and an unfolded (folded) state as shown in fig. 1 and a closed (folded) state as shown in fig. 2 are caused. When the first screen 110 is unfolded relative to the body 160 through the rotation shaft 170, a user can pull out or move in the second screen 120 from the rear of the first screen 110 according to a requirement, so that the foldable electronic device 100 has both the display functions of a single screen (i.e., only the first screen 110) and multiple screens (i.e., the first screen 110 plus at least one second screen 120).

As shown in fig. 2 and 3, the second screen 120, the worm 130 and the link 150 are all located on the same surface (i.e., the back surface P3) of the first screen 110, and face away from the display surface P1 of the first screen 110. In other words, the first screen 110 has a display surface P1 and a back surface P3 opposite to the display surface P1, and the sliding slot structure 112 is located at the back surface P3, and the second screen 120 is movably disposed on the sliding slot structure 112 to move into the sliding slot structure 112 completely or partially out of the sliding slot structure 112. Here, the pair of second screens 120 are respectively disposed on opposite sides of the worm 130, the first screen 110 further has a plurality of ribs 113 and 114 located on the sliding slot structure 112, and the second screens 120 movably abut on the ribs 113 and 114 to reduce a contact area between the second screens 120 and the first screen 110, so that a sliding process of the second screens 120 relative to the first screen 110 can be smoothly performed.

Furthermore, the first screen 110 further has a rail 111 located on the back P3, and the pair of second screens 120 are respectively connected to the same moving member 140 through a plurality of connecting rods 150, so that when the moving member 140 moves along the worm 130, the pair of second screens 120 can be synchronously driven to move out of or into the first screen 110 through the connecting rods 150. In detail, the worm 130 has a threaded groove 131, and the moving member 140 includes a sleeve 141 and wings 142 at two opposite sides of the sleeve 141, wherein the sleeve 141 has a guiding post (not shown) movably coupled to the groove 131, for example, so that when the worm 130 rotates around the axis X2, the moving member 140 moves along the worm 130 by the matching of the guiding post and the groove 131, as shown in fig. 2 and 3, wherein fig. 3 is the same state as fig. 1, the second screen 120 is pulled out from the back P3 of the first screen 110, and the display surface P1 of the first screen 110 faces the same direction as the display surface P2 of the second screen 120.

Furthermore, one end of the link 150 is pivotally connected to the moving member 140, and the other end of the link 150 is pivotally connected to the second screen 120 and is movably coupled to the rail 111, wherein the extending direction of the rail 111 is orthogonal to the extending direction of the worm 130, so that when the worm 130 rotates, the moving member 140 moves along the worm 130, and simultaneously, the link 150 can synchronously drive the second screen 120 to move closer to or away from the worm 130. Here, each second screen 120 is correspondingly pivoted with a plurality of links 150, and the links 150 corresponding to the same second screen 120 are parallel to each other. This allows the moving member 140 to synchronously drive the pair of second screens 120 through the connecting rod 150, and simultaneously, the stability of the second screens 120 can be maintained without torsion.

Fig. 4 is a schematic view of a foldable electronic device according to another embodiment of the present invention. Referring to fig. 4, different from the above-mentioned embodiment, the foldable electronic device 200 of the present embodiment further includes an orthogonal gear set disposed between the worm 130 and the rotating shaft 270, so that the rotating shaft 270 can drive the worm 130 to rotate about the axis X2 through the orthogonal gear set in the process of performing the rotation opening and closing of the first screen 110 through the rotating shaft 270. Here, the orthogonal gear set includes a first bevel gear G1 and a second bevel gear G2 that are engaged with each other, the first bevel gear G1 is coaxially assembled to the rotation shaft 270 so that the first bevel gear G1 rotates in synchronization with the rotation shaft 270, and the second bevel gear G2 is coaxially assembled to the worm 130 so that the second bevel gear G2 rotates in synchronization with the worm 130.

In this way, while the first screen 110 rotates through the rotating shaft 270, the worm 130 is synchronously rotated through the meshing relationship between the first helical gear G1 and the second helical gear G2, so that the second screen 120 gradually moves out from the back of the first screen 110 during the unfolding process of the foldable electronic device 200, or the second screen 120 gradually moves into the back of the first screen 110 during the closing process of the foldable electronic device 200.

In summary, in the above embodiments of the present invention, the foldable electronic device can move the at least one second screen to be disposed behind the first screen, and the worm, the moving member and the connecting rod are used as the driving mechanism thereof, so that the worm can drive the second screen to move relative to the first screen via the moving member and the connecting rod when rotating, so that the user can pull out or move in the second screen from behind the first screen, thereby satisfying the requirement of single-screen display or multi-screen display of the user.

Moreover, because the second screen and the related driving mechanism are arranged at the back of the first screen, better visual effect can be provided for the user during operation. That is to say, with the above configuration of the components, the first screen of the present invention can also be used as the accommodating space for the second screen and the driving mechanism, so that the foldable electronic device can avoid the interference of the mechanism no matter in the single-screen operation or the multi-screen operation.

Furthermore, when the foldable electronic device is provided with two second screens, the second screens are respectively connected to the same moving member through the connecting rods, so that when the worm rotates to move the moving member, the connecting rods can synchronously drive the second screens to move out of the first screen or move into the back of the first screen, and the umbrella stand structure formed by the worm, the moving member and the connecting rods achieves the effect of synchronous driving.

Furthermore, the foldable electronic device can complete the moving-out or moving-in action of the second screen in the process of the screen rotating opening and closing through the orthogonal gear set arranged between the worm and the rotating shaft, so that the foldable electronic device can provide additional operation modes.
