Description

Technical Field

[0001] The invention relates to a foldable electronic device. Background Art

[0002] As people's living standards continue to improve, electronic products have become an indispensable part of their lives. In line with these shifts in lifestyle, the types and models of electronic products on the market have become increasingly diverse. Among them, foldable electronic products, such as smartphones and tablets, are also popular among consumers.

[0003] In order to meet the needs of consumers, how to make the screen fold safely in foldable electronic products is undoubtedly a very important development direction in the industry. For example, US Patent No. US9857832B2 discloses a foldable electronic device 10 (see Figures 1-2 ), wherein the flexible screen 20 of the foldable electronic device 10 can be opened or folded as the foldable electronic device 10 is opened and closed, and the foldable electronic device 10 uses support members 30 and 40 to provide support for the flexible screen 20.

[0004] However, please refer to Figure 3 . Figure 3 To illustrate Figures 1-2 Schematic diagram of the operation of the support members 30 and 40. Obviously, Figure 3 It can be clearly seen that the position at which the support members 30 and 40 contact the flexible screen 20 changes as the angle of the foldable electronic device 10 is opened (for example, moving from contact point E on the flexible screen 20 to contact point F). Therefore, there is a chance that the foldable electronic device 10 may scratch the flexible screen 20 due to friction.

[0005] The present invention can at least solve the above problems. That is, in addition to allowing the flexible screen of the foldable electronic device to maintain a flat surface when in use, it can also prevent the flexible screen from being scratched when the foldable electronic device switches between the use state and the storage state.

[0072] Unless otherwise defined, all words used herein (including technical and scientific terms) have their ordinary meanings as understood by those skilled in the art. Furthermore, the definitions of the above-mentioned words in commonly used dictionaries should be interpreted in the context of this specification as having the same meanings as those in the relevant field of the present invention. Unless otherwise explicitly defined, these words should not be interpreted as having idealized or overly formal meanings.

[0073] Please refer to Figures 4 to 7 . Figure 4 FIG1 is a perspective diagram illustrating a foldable electronic device 100 according to an embodiment of the present invention, wherein the foldable electronic device 100 is in a stored state. Figure 5 To illustrate Figure 4 Schematic diagram of a foldable electronic device 100, wherein the angle θ between the first body 121 and the second body 131 is 60 degrees. Figure 6 To illustrate Figure 4 1 is a three-dimensional schematic diagram of a foldable electronic device 100, wherein the angle θ between the first body 121 and the second body 131 is 120 degrees. Figure 7 To illustrate Figure 4 The foldable electronic device 100 is a three-dimensional schematic diagram, wherein the angle θ between the first body 121 and the second body 131 is 180 degrees, that is, the foldable electronic device 100 is in use. Figures 4 to 7 As shown, the foldable electronic device 100 includes a support base 110, a first structure 120, a second structure 130, and a flexible screen 140. The first structure 120 and the second structure 130 are respectively pivotally connected to the support base 110, while the flexible screen 140 connects the first structure 120 and the second structure 130. In practical applications, the foldable electronic device 100 can be a smartphone or a tablet computer, but the present invention is not limited thereto.

[0074] Specifically, when the foldable electronic device 100 is Figure 4When the foldable electronic device 100 is in the retracted state, the first structure 120 and the second structure 130 are attached to each other, and the flexible screen 140 is folded in half. As the foldable electronic device 100 is gradually unfolded, the angle θ between the first structure 120 and the second structure 130 also gradually increases. Figures 5-6 As shown, the angles θ between the first structure 120 and the second structure 130 are 60 degrees and 120 degrees respectively, and the flexible screen 140 gradually unfolds and tends to be flat. Figure 7 In the illustrated use state, the angle θ between the first structure 120 and the second structure 130 is 180 degrees, and the flexible screen 140 is flat, facilitating user operation. In other words, when the foldable electronic device 100 switches between the stored and use states, the shape of the flexible screen 140 changes from a folded state to a flat state, or vice versa.

[0075] Please refer to Figures 8-10 . Figure 8 To illustrate Figure 7 Schematic perspective view of a foldable electronic device 100, wherein the flexible screen 140 is omitted. Figure 9 To illustrate Figure 8 1 is a three-dimensional schematic diagram of a foldable electronic device 100, wherein the flexible screen 140 and the screen support plate 151 are omitted. Figure 10 To illustrate Figure 9 In this embodiment, as shown in FIG. Figures 8-10 As shown, the foldable electronic device 100 also includes a screen support structure 150. Furthermore, the first structure 120 includes a first body 121, a first protrusion 122 and a first shaft 123. The first shaft 123 is connected between the first body 121 and the first protrusion 122, and the first shaft 123 is pivotally connected to the support base 110 along the first axis X1. The second structure 130 includes a second body 131, a second protrusion 132 and a second shaft 133. The above-mentioned angle θ is formed between the second body 131 of the second structure 130 and the first body 121 of the first structure 120. The second shaft 133 is connected between the second body 131 and the second protrusion 132, and the second shaft 133 is pivotally connected to the support base 110 along the second axis X2, and the second axis X2 is parallel to the first axis X1. Specifically, the first shaft 123 and the second shaft 133 achieve synchronous rotation through mechanical linkage, for example, through Figure 10 The gear assembly 170 is mechanically connected between the first structure 120 and the second structure 130 to simultaneously move the first structure 120 and the second structure 130 toward or away from each other. Furthermore, the screen support structure 150 is at least partially located between the first structure 120 and the second structure 130 and is movably connected to the support base 110.

[0076] Please refer to Figures 10-11 . Figure 11 To illustrate Figure 10 A cross-sectional view along line segment BB. In this embodiment, as Figures 10-11 As shown, the support base 110 includes a bottom plate 111, a top plate 112, and at least one connecting portion 113. The top plate 112 has at least one through hole H. The connecting portion 113 is connected between the top plate 112 and the bottom plate 111, and a space S is defined between the top plate 112 and the bottom plate 111, and the space S is connected to the through hole H. In addition, the screen support structure 150 includes a screen support plate 151, at least one limiting portion 152, and at least one connecting rod 153 (see the screen support plate 151, the limiting portion 152, and the connecting rod 153 for details). Figure 11 ). The screen support plate 151 is configured to at least partially contact the flexible screen 140 (the flexible screen 140 is Figures 8-10 Omitted, please refer to Figure 11 ). The limiting portion 152 is located in the space S and its size is larger than the through hole H of the top plate 112. Therefore, the limiting portion 152 cannot pass through the through hole H. Therefore, the limiting portion 152 can be configured to abut the top plate 112 of the support base 110 to prevent the screen support structure 150 from detaching from the support base 110. The connecting rod 153 passes through the through hole H of the top plate 112 and is connected between the screen support plate 151 and the limiting portion 152. In other words, the top plate 112 is located between the screen support plate 151 and the limiting portion 152. Furthermore, as Figure 11 As shown, the flexible screen 140 connects the first body 121 of the first structure 120 and the second body 131 of the second structure 130. When the angle θ between the first body 121 and the second body 131 is 180 degrees, the screen support plate 151 moves toward the flexible screen 140 relative to the support base 110 and at least partially contacts the flexible screen 140 to provide support for the flexible screen 140, so that the flexible screen 140 can maintain a flat state.

[0077] Please refer to Figure 12 . Figure 12 To illustrate Figure 10 Cross-sectional view along line CC. In this embodiment, the first protrusion 122 of the first structure 120 and the second protrusion 132 of the second structure 130 are at least partially located between the screen support plate 151 and the bottom plate 111. Figure 12As shown, when the angle θ increases from less than 180 degrees to 180 degrees, as the first structure 120 and the second structure 130 rotate, the first protrusion 122 and the second protrusion 132 respectively at least partially press the screen support plate 151, so that the screen support plate 151 can move toward the flexible screen 140 along the normal direction N of the flexible screen 140, and the screen support plate 151 at least partially contacts the flexible screen 140 to provide support for the flexible screen 140, thereby making it simple and easy to maintain the flexible screen 140 in a flat state. At this time, as shown in FIG. Figure 11 As shown, the stopper 152 of the screen support structure 150 also moves toward the top plate 112 of the support base 110. It is worth noting that because the screen support plate 151 moves toward the flexible screen 140 along the normal direction N of the flexible screen 140 and at least partially contacts the flexible screen 140, the screen support plate 151 does not slide on the surface of the flexible screen 140, thereby preventing the screen support plate 151 from scratching the flexible screen 140.

[0078] Please refer to Figure 13 . Figure 13 To illustrate Figure 4 A cross-sectional view along line segment DD. In this embodiment, as Figure 13 As shown, when the foldable electronic device 100 is in the stowed state, that is, when the angle θ between the second body 131 and the first body 121 decreases from greater than 0 degrees to 0 degrees, the first protrusion 122 and the second protrusion 132 no longer press against the screen support plate 151 of the screen support structure 150 as the first structure 120 and the second structure 130 rotate. In other words, when the angle θ is 0 degrees, the first protrusion 122 and the second protrusion 132 are separated from the screen support structure 150, meaning that the first protrusion 122 and the second protrusion 132 no longer support the screen support plate 151. At this point, the screen support structure 150 can, for example, move toward the bottom plate 111 of the support base 110 under its own weight, away from the flexible screen 140. This means that the screen support structure 150 and the flexible screen 140 are separated from each other. This allows the screen support structure 150 to create space to accommodate the folded portion of the flexible screen 140.

[0079] Please refer to Figure 14 . Figure 14 To illustrate Figure 4 A cross-sectional view along line segment EE. In this embodiment, as Figure 14 As shown, when the angle θ is 0 degrees, the screen support plate 151 of the screen support structure 150 loses the support of the first protrusion 122 and the second protrusion 132, and the limiting portion 152 of the screen support structure 150 also moves away from the top plate 112 of the support base 110 and toward the bottom plate 111.

[0080] Please refer to Figure 15 . Figure 15 FIG2 is a cross-sectional view of a foldable electronic device 100 according to another embodiment of the present invention, wherein an elastic element 160 is elastically connected between the screen support structure 150 and the support base 110. In this embodiment, the foldable electronic device 100 further includes an elastic element 160. For example, in practical applications, the elastic element 160 may be a spring, but the present invention is not limited thereto. Figure 15 As shown, the elastic element 160 is elastically connected between the limiting portion 152 of the screen support structure 150 and the top plate 112 of the support base 110, and the connecting rod 153 of the screen support structure 150 passes through the elastic element 160. When the foldable electronic device 100 is in use, that is, when the angle θ between the first body 121 and the second body 131 increases from less than 180 degrees to 180 degrees, as described above, the first protrusion 122 and the second protrusion 132 respectively rotate with the first structure 120 and the second structure 130 to at least partially press against the screen support plate 151, causing the screen support plate 151 to move toward the flexible screen 140 along the normal direction N of the flexible screen 140 and at least partially contact the flexible screen 140. At the same time, the limiting portion 152 of the screen support structure 150 also moves toward the top plate 112 of the support base 110, causing the elastic element 160 connected between the top plate 112 and the limiting portion 152 to be compressed and shortened, thereby storing a certain amount of elastic potential energy.

[0081] Please refer to Figure 16 . Figure 16 To illustrate Figure 15 1 is a cross-sectional view of the foldable electronic device 100, wherein the elastic element 160 has been reset. Figure 16 As shown, when the foldable electronic device 100 is in the stored state, that is, when the angle θ between the first body 121 and the second body 131 decreases from greater than 0 degrees to 0 degrees, as described above, the first protrusion 122 and the second protrusion 132 no longer press against the screen support plate 151 as the first structure 120 and the second structure 130 rotate. In other words, when the angle θ between the first body 121 and the second body 131 is 0 degrees, the first protrusion 122 and the second protrusion 132 are separated from the screen support structure 150. In other words, the first protrusion 122 and the second protrusion 132 no longer support the screen support plate 151. The compressed elastic element 160 elastically returns to its original position and releases its stored elastic potential energy, allowing the screen support plate 151 of the screen support structure 150 to move toward the support base 110 and easily away from the flexible screen 140. At this point, the screen support structure 150 and the flexible screen 140 are separated from each other.

[0082] Please refer to Figure 17 . Figure 17The cross-sectional view of a foldable electronic device 100 according to another embodiment of the present invention is shown, wherein the flexible screen 140 at least partially presses against the screen support structure 150 and causes the screen support structure 150 to move toward the support base 110. In this embodiment, Figure 17 As shown, when the angle θ between the first body 121 and the second body 131 decreases from greater than 0 degrees to 0 degrees, the flexible screen 140 at least partially presses against the screen support plate 151 of the screen support structure 150, causing the screen support structure 150 to move toward the bottom plate 111 of the support base 110. Specifically, as described above, when the angle θ between the first body 121 and the second body 131 is 0 degrees, the first protrusion 122 of the first structure 120 and the second protrusion 132 of the second structure 130 are separated from the screen support structure 150. In other words, the first protrusion 122 and the second protrusion 132 no longer provide support for the screen support plate 151. Therefore, the pressure of the flexible screen 140 against the screen support plate 151 allows the screen support structure 150 to be easily moved toward the bottom plate 111 of the support base 110, facilitating the return of the foldable electronic device 100 to the stored state.

[0083] In summary, the technical solutions disclosed in the above embodiments of the present invention have at least the following advantages:

[0084] (1) When the angle between the first body and the second body increases from less than 180 degrees to 180 degrees, the first protrusion of the first structure and the second protrusion of the second structure respectively at least partially press the screen support plate of the screen support structure, so that the screen support plate moves toward the flexible screen relative to the support seat and at least partially contacts the flexible screen to provide support for the flexible screen, thereby enabling the flexible screen to be maintained in a flat state simply and easily.

[0085] (2) When the angle between the first body and the second body increases from less than 180 degrees to 180 degrees, since the screen support plate moves toward the flexible screen along the normal direction of the flexible screen and at least partially contacts the flexible screen, the screen support plate will not slide on the surface of the flexible screen, thereby avoiding the chance of the screen support plate scratching the flexible screen.

[0086] (3) When the angle between the first body and the second body decreases from greater than 0 degrees to 0 degrees, the first protrusion and the second protrusion respectively move away from the screen support structure, and the compressed elastic element elastically resets and releases the stored elastic potential energy, so that the screen support plate of the screen support structure moves toward the support seat and can be easily and simply moved away from the flexible screen.

[0087] (4) When the angle between the first body and the second body decreases from greater than 0 degrees to 0 degrees, the first protrusion and the second protrusion are respectively away from the screen support structure. Therefore, through the pressure of the flexible screen on the screen support plate, the screen can make the screen support structure move toward the bottom plate of the support base simply and easily, which is conducive to restoring the foldable electronic device to the storage state.

[0088] Although the present invention has been disclosed above in terms of embodiments, this is not intended to limit the present invention. Anyone skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the appended claims.
