Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to an electronic equipment. Background Art

[0002] In the related art, a rollable screen mobile phone usually has a comb-shaped support plate. When the mobile phone is extended, the gaps between the comb teeth will cause an uneven touch when the user touches the screen. In addition, the touch screen in the gap is easily damaged when impacted by a large external force. Summary of the invention

[0003] The present application aims to provide an electronic device that can solve or improve the technical problem in the related art that an electronic device with a curling screen is easily damaged due to the use of a comb-shaped support plate.

[0004] In order to solve the above technical problems, this application is implemented as follows:

[0005] In a first aspect, the present application provides an electronic device, including:

[0006] a first shell;

[0007] a second housing, the second housing being movable relative to the first housing;

[0008] A folding plate assembly, one end of which is connected to the first shell, and the other end of which is connected to the second shell, and the folding plate assembly has an unfolded state and a folded state;

[0009] A flexible screen assembly is provided between the first shell and the second shell;

[0010] Among them, when the folding plate assembly is in an unfolded state, the first shell and the second shell drive the flexible screen assembly to unfold; when the folding plate assembly is in a folded state, the first shell and the second shell drive the flexible screen assembly to fold.

[0011] In an embodiment of the present application, the electronic device includes a first shell, a second shell and a flexible screen assembly. The first shell and the second shell can perform relative or opposite translational activities. The first shell and the second shell can perform opposite translational movements to increase the volume of the first shell and the second shell, thereby driving the flexible screen assembly to expand and increase the display area of ​​the flexible screen assembly. The first shell and the second shell can also perform opposite translational movements to reduce the volume of the first shell and the second shell, thereby driving the flexible screen assembly to collapse and reduce the overall volume of the electronic device, thereby increasing the display area of ​​the electronic device and reducing the space occupied by the electronic device when stored.

[0012] Among them, the electronic device also includes a folding plate assembly connected to the first shell and the second shell, and as the first shell and the second shell move, the folding plate assembly can be pulled to switch the folding plate assembly between an unfolded state and a folded state. When the folding plate assembly is in the folded state, the two ends of the first shell and the second shell are close to each other, so that the flexible screen assembly is folded.

[0013] When the folding plate assembly is in the unfolded state, the two ends of the first shell and the second shell are separated from each other, thereby propping up the flexible screen assembly and allowing the flexible screen assembly to unfold. At this time, the folding plate assembly is located below the flexible screen assembly, and the folding plate assembly can provide support for the flexible screen assembly. Since the folding plate assembly forms a plate-like structure when in the unfolded state, that is, the folding plate assembly has no gaps between the comb teeth, the impact resistance of the flexible screen assembly is improved, and there is no uneven touch when the user touches the flexible screen assembly.

[0032] Combine the following Figures 1 to 10 An electronic device 100 according to an embodiment of the present application is described.

[0033] like Figures 1 to 6 As shown, the present application provides an electronic device 100, including: a first shell 110; a second shell 120, the second shell 120 is movable relative to the first shell 110; a folding plate assembly 130, one end of which is connected to the first shell 110, and the other end is connected to the second shell 120, the folding plate assembly 130 has an unfolded state and a folded state; a flexible screen assembly 160, which is arranged in the first shell 110 and the second shell 120; wherein, when the folding plate assembly 130 is in the unfolded state, the first shell 110 and the second shell 120 drive the flexible screen assembly 160 to unfold; when the folding plate assembly 130 is in the folded state, the first shell 110 and the second shell 120 drive the flexible screen assembly 160 to fold.

[0034] In an embodiment of the present application, the electronic device 100 includes a first shell 110, a second shell 120 and a flexible screen assembly 160. The first shell 110 and the second shell 120 can perform relative or opposite translation activities. The first shell 110 and the second shell 120 can perform opposite translation movements to increase the volume of the first shell 110 and the second shell 120, thereby driving the flexible screen assembly 160 to expand and increase the display area of ​​the flexible screen assembly 160. The first shell 110 and the second shell 120 can also perform opposite translation movements to reduce the volume of the first shell 110 and the second shell 120, thereby driving the flexible screen assembly 160 to collapse and reduce the overall volume of the electronic device 100, thereby increasing the display area of ​​the electronic device 100 and reducing the space occupied by the electronic device when it is stored.

[0035] The electronic device 100 further includes a folding plate assembly 130 connected to the first housing 110 and the second housing 120. As the first housing 110 and the second housing 120 move, the folding plate assembly 130 can be pulled so that the folding plate assembly 130 switches between an unfolded state and a folded state. Figure 1 , Figure 2 and Figure 3 As shown, when the folding plate assembly 130 is in a folded state, both ends of the first shell 110 and the second shell 120 are close to each other, so that the flexible screen assembly 160 is folded.

[0036] like Figure 4 , Figure 5 and Figure 6 As shown, when the folding plate assembly 130 is in the unfolded state, the two ends of the first shell 110 and the second shell 120 are far away from each other, thereby stretching the flexible screen assembly 160 and allowing the flexible screen assembly 160 to unfold. At this time, the folding plate assembly 130 is located below the flexible screen assembly 160, and the folding plate assembly 130 can provide support for the flexible screen assembly 160. Since the folding plate assembly 130 forms a plate-like structure when in the unfolded state, that is, the folding plate assembly 130 does not have a gap between the comb teeth, the impact resistance of the flexible screen assembly 160 is improved, and when the user touches the flexible screen assembly 160, there is no uneven touch.

[0037] Furthermore, the folding plate assembly 130 can save the internal space of the electronic device 100 by switching between the folding and unfolding states, and has a larger telescopic displacement.

[0038] Furthermore, the adhesive area of ​​the folding plate assembly 130 and the first body to the flexible screen assembly 160 is much larger than the area of ​​the comb-tooth support frame, thereby improving the reliability of the flexible screen assembly 160 and reducing the possibility of debonding and separation of the flexible screen assembly 160.

[0039] As a possible implementation, Figure 7 As shown, the folding plate assembly 130 includes: a plurality of support plates 132, the plurality of support plates 132 are arranged side by side, and adjacent support plates 132 are rotatable.

[0040] Specifically, the folding plate assembly 130 includes a plurality of support plates 132, and the plurality of support plates 132 are arranged side by side, and adjacent support plates 132 can rotate, so that when the folding plate assembly 130 is in an unfolded state, the plurality of support plates 132 are sequentially connected and flattened into a long plate shape, so that the flexible screen assembly 160 can be supported under the flexible screen assembly 160. When the folding plate assembly 130 is in a folded state, adjacent support plates 132 rotate, so that the front side of one support plate 132 and the back side of another support plate 132 are opposite to each other, so that the plurality of support plates 132 are folded together to reduce the space occupied by the support plate assembly 130.

[0041] Furthermore, by controlling the number of support parts in the folding plate assembly 130 , different telescopic displacements of the flexible screen assembly 160 can be achieved.

[0042] In addition, the gap between the support plates 132 is small, which reduces the uneven feeling of the flexible screen assembly 160 during touch control, improves the support strength of the flexible screen assembly 160, and improves the protection effect of the flexible screen assembly 160.

[0043] As a possible implementation, Figure 7 As shown, the folding plate assembly 130 further includes a hinge 134 , and adjacent support plates 132 are connected via the hinge 134 .

[0044] Specifically, the folding plate assembly 130 further includes a hinge 134 connecting adjacent support plates 132 , that is, the adjacent support plates 132 are connected by a hinge 134 to achieve rotational connection, and the structure is simple and easy to produce.

[0045] A plurality of hinges 134 may be provided between adjacent support plates 132 , for example, on both sides of the support plates 132 , so that there are two connection points between adjacent support plates 132 , thereby improving the stability of the unfolding and folding of the folding plate assembly 130 .

[0046] like Figure 6 As shown, when the folding plate assembly 130 is in the unfolded state, the adjacent support plates 132 are unfolded into a flat plate shape, such as a "-" shape, such as Figure 3 As shown, when the folding plate assembly 130 is in the folded state, the adjacent support plates 132 are folded into a “||” shape or a “V” shape.

[0047] As a possible implementation, Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, the folding plate assembly 130 also includes: a first roller 140, which is arranged on the hinge 134 and protrudes from the support plate 132. A guide rail 126 is arranged on the second shell 120, and the first roller 140 is arranged in the guide rail 126; wherein, among adjacent hinges 134, at most one hinge 134 is provided with a first roller 140.

[0048] Specifically, the folding plate assembly 130 further includes a first roller 140 disposed on the hinge 134, and a guide rail 126 is disposed on the second housing 120. The first roller 140 can slide in the guide rail 126, thereby limiting the motion trajectory of the folding plate assembly 130 and improving the stability of the operation of the folding plate assembly 130. There are two guide rails 126, and there are multiple first rollers 140, which are respectively disposed on both sides of the support plate 132. The guide rails 126 are also located on both sides of the support plate 132, and the guide rails 126 and the first rollers 140 located on the same side of the support plate 132 cooperate with each other.

[0049] Furthermore, in the direction from one support plate 132 to another support plate 132, only one of the adjacent hinges 134, that is, the hinges 134 on both sides of the same support plate 132, is provided with a first roller 140, so that the folding and unfolding of the folding plate assembly 130 can be realized. Specifically, when the folding plate assembly 130 is in a folded state, the first roller 140 is located in the guide rail 126, and then the hinge 134 in the adjacent support plate 132 that is not provided with the first roller 140 moves to one side of the guide rail 126, thereby forming a folded state.

[0050] Furthermore, a plurality of hinges 134 may be disposed between adjacent support plates 132 . There are two first rollers 140 , which are disposed on different hinges 134 between adjacent support plates 132 , respectively. The two first rollers 140 protrude from both sides of the support plate 132 .

[0051] During the transition from the folded state to the unfolded state of the folding plate assembly 130, the adjacent support plates 132 are formed into a "V" shape from a flat plate, and the angle between the adjacent support plates 132 gradually decreases until it is completely folded. During the transition from the unfolded state to the folded state of the folding plate assembly 130, the adjacent support plates 132 are formed into a "V" shape from a folded state, and the angle between the adjacent support plates 132 gradually increases until it is completely unfolded.

[0052] Furthermore, when the folding plate assembly 130 is in the unfolded state, the first roller 140 can support the folding plate assembly 130 on the guide rail 126 , thereby improving the supporting ability of the folding plate assembly 130 for the flexible screen assembly 160 .

[0053] The hinge 134 includes a hinge shaft 152 , and the first gear is disposed on the hinge shaft 152 .

[0054] As a possible implementation, Figure 7 As shown, the folding plate assembly 130 further includes: a synchronous gear set 142 , which is disposed on the adjacent support plate 132 .

[0055] Specifically, the folding plate assembly 130 further includes a synchronous gear set 142 disposed between adjacent support plates 132, so that when the adjacent support plates 132 rotate, the multiple support plates 132 rotate synchronously, so that the rotation angles between the support plates 132 are substantially the same, so that the folding plate assembly 130 is evenly stressed. In addition, since the diameter of the synchronous gear set 142 is small, the gap is small after the folding plate assembly 130 is unfolded to a horizontal unfolded state, and the folding plate assembly 130 can well support and protect the flexible screen assembly 160.

[0056] A plurality of hinges 134 may be provided between adjacent support plates 132 , and the synchronous gear set 142 is provided between two hinges 134 , that is, the synchronous gear set 142 is located between the two support plates 132 in the transverse direction and between the two hinges 134 in the longitudinal direction.

[0057] Specifically, the synchronous gear set 142 can be two meshing gears, the two hinge 134 components are provided with two support rods 154, and the two gears are respectively provided on the two support rods 154.

[0058] As a possible implementation, Figure 7 As shown, the hinge 134 includes a translation hinge 136 and a spatial hinge 138 . The translation hinge 136 and the spatial hinge 138 are alternately arranged, and the first roller 140 is arranged on the translation hinge 136 .

[0059] Specifically, the hinge 134 includes a translation hinge 136 and a spatial hinge 138, the first roller 140 is provided on the translation hinge 136, and the translation hinge 136 and the spatial hinge 138 are alternately provided between different support plates 132. The translation hinge 136 refers to the hinge 134 that moves only along the movement direction of the first shell 110 and the second shell 120 during the movement of the folding plate assembly 130. The spatial hinge 138 refers to the hinge 134 that moves not only along the movement direction of the first shell 110 and the second shell 120, but also along the movement direction perpendicular to the first shell 110 and the second shell 120 during the movement of the folding plate assembly 130.

[0060] For example, the folding plate assembly 130 includes four support plates 132, namely, a first support plate, a second support plate, a third support plate and a fourth support plate, and the four support plates 132 are connected in sequence, wherein a space hinge 138 is provided between the first support plate and the second support plate, a translation hinge is provided between the second support plate and the third support plate, and a space hinge 138 is provided between the third support plate and the fourth support plate.

[0062] Specifically, the first housing 110 includes a first frame 112 and a fixed bracket 114 disposed on the first frame 112, and the second housing 120 includes a second frame 122, the second frame 122 is movably disposed on the first frame 112, and the second frame 122 and the first frame 112 can move toward and away from each other, wherein one end of the folding plate assembly 130 is connected to the fixed bracket 114, and the other end is connected to the second frame 122. That is, one support plate 132 in the folding plate assembly 130 is connected to the fixed bracket 114, and the other is connected to the second frame 122, and the folding plate assembly 130 can be pulled apart when the fixed bracket 114 and the second frame 122 move away from each other, and the folding plate assembly 130 can be pushed to a folded state when the fixed bracket 114 and the second frame 122 move toward each other.

[0063] Among them, Fig.10 As shown, a groove is provided on the fixing bracket 114, and the guide rail 126 on the second shell 120 can slide in the groove.

[0064] Furthermore, a third rotating shaft 124 is also provided on the second frame 122 , and the flexible screen assembly 160 can be wound on the third rotating shaft 124 .

[0066] Specifically, the folding plate assembly 130 and the first shell 110 are connected via a first rotating shaft 144, and the folding plate assembly 130 and the second shell 120 are connected via a second rotating shaft 146, so that the folding plate assembly 130 and the first shell 110 are rotatably connected, and the folding plate assembly 130 and the second shell 120 are rotatably connected, so that when the folding plate assembly 130 is in a folded state, it has a smaller volume.

[0067] Among them, the support plate 132 connected to the first shell 110 in the folding plate assembly 130 and one of the first shells 110 has a protrusion, and the other has a recess, the protrusion is embedded in the recess, and the first shaft 144 passes through the first shell 110 and the support plate 132.
