Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of folding devices, and specifically relates to an electronic device. Background Art
[0002] At present, after existing folding mobile phones are folded multiple times, there will usually be misalignment of multiple laminated structures at the folding position due to the adhesive connection between the various laminated structures in the flexible screen, resulting in creases. In related technologies, space is usually provided inside the mobile phone for the bent part of the flexible screen to avoid, but this avoidance will cause the flexible screen to be suspended, which is more likely to cause creases. Summary of the invention
[0003] The present application aims to provide an electronic device, which, by arranging a first plate and a second plate with magnetism on the back side of a flexible screen, can provide support for the flexible screen when it is folded, limit the range of its free deformation, and solve the technical problem of obvious creases.
[0004] In order to achieve the above-mentioned purpose, an embodiment of the present application provides an electronic device, comprising: a first folding body, a second folding body and a connecting component arranged between the first folding body and the second folding body, the first folding body and the second folding body being able to switch between a folded state and an unfolded state through the connecting component; a flexible screen, part of the flexible screen being arranged on the first surface of the first folding body and the second folding body, the flexible screen comprising a bending zone arranged opposite to the connecting component; the connecting component comprising two first plates arranged corresponding to the two sides of the bending zone and a second plate arranged corresponding to the bending axis of the bending zone, the second plate being movable in a direction from the inside to the outside of the electronic device; a first magnetic component being arranged in the bending zone of the flexible screen; a second magnetic component being arranged on the side of the first plate and the second plate facing the flexible screen; wherein the first magnetic component and the second magnetic component attract each other.
[0005] According to the embodiment of the electronic device provided by the present application, it mainly includes a first folding body and a second folding body connected and foldable to each other through a connecting component, as well as a flexible screen and two magnetic parts, wherein the two folding bodies are rotatably connected, and a connecting component is provided between the first folding body and the second folding body, which can be used to realize the rotational connection between the two, so that the first folding body and the second folding body can be switched between a folded state and an unfolded state. It can be understood that in the folded state, the first folding body and the second folding body are in contact with each other, and in the unfolded state, the first folding body and the second folding body are flat, so as to facilitate the large-size display of the flexible screen. Specifically, the flexible screen is arranged on one side of the first folding body and the second folding body. When the first folding body and the second folding body are relatively folded, the shape of some structures in the flexible screen will change, and the area that changes at this time is the bending area relative to the position of the connecting component. As for the connecting component for connecting two folding bodies, it includes two first plates and a second plate. The second plate and the bending axis of the bending zone are arranged correspondingly, that is, the second plate covers the center of the bending zone, and the two first plates are respectively located on both sides of the second plate, and are arranged correspondingly to the opposite sides of the bending zone. When the first folding body and the second folding body are folded, the second plate will float up and down, that is, it will move in the direction from the inside to the outside of the electronic device, thereby achieving a certain avoidance effect on the folded flexible screen.
[0006] It should be emphasized that a second magnetic member is provided on the first plate and the second plate, which can generate magnetic attraction with the first magnetic member on the flexible screen. When folding occurs, the second plate will move downward, that is, move away from the flexible screen. Under the action of the magnetic force of the first magnetic member and the second magnetic member, the bending area of the flexible screen will be attracted. The degree of free deformation of the flexible screen is small, and a water drop angle can be formed more easily. The bending stress generated after the flexible screen is bent can be significantly weakened, thereby reducing screen deformation. When unfolded, the crease can be weakened, greatly improving the user experience.
[0007] Among them, electronic devices include foldable mobile phones, foldable tablets, cameras, camcorders, notebooks and other devices with foldable screens.
[0008] Additional aspects and advantages of the present application will become apparent in the following description or will be learned through practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Refer to the following Figures 1 to 7 An electronic device provided according to an embodiment of the present application is described.
[0023] like Figure 1 and Figure 2 As shown, one embodiment of the present application provides an electronic device 200, comprising: a first folding body 102, a second folding body 104, and a connecting component 108 disposed between the first folding body 102 and the second folding body 104, the first folding body 102 and the second folding body 104 can be switched between a folded state and an unfolded state through the connecting component 108; a flexible screen 106, a portion of the flexible screen 106 is disposed on a first surface of the first folding body 102 and the second folding body 104, the flexible screen 106 includes a bending Zone 1062; the connecting component 108 includes two first plates 1082 corresponding to the two sides of the bending zone 1062 and a second plate 1084 corresponding to the bending axis of the bending zone 1062, and the second plate 1084 is movable in the direction from the inside to the outside of the electronic device 200; the first magnetic member 1102 is arranged in the bending zone of the flexible screen 106; the second magnetic member 1104 is arranged on the side of the first plate 1082 and the second plate 1084 facing the flexible screen 106; wherein the first magnetic member 1102 and the second magnetic member 1104 attract each other.
[0024] According to an embodiment of the electronic device 200 provided in the present application, it mainly includes a first folding body 102 and a second folding body 104 which are connected and foldable to each other through a connecting component, a flexible screen 106 and two magnetic parts, wherein the two folding bodies are rotatably connected, and a connecting component 108 is also provided between the first folding body 102 and the second folding body 104 for realizing the rotational connection between the two, so that the first folding body and the second folding body can be switched between a folded state and an unfolded state. It can be understood that in the folded state, the first folding body and the second folding body are in contact with each other, and in the unfolded state, the first folding body and the second folding body are flat, so as to facilitate the large-size display of the flexible screen. Specifically, the flexible screen 106 is arranged on the first surface. When the first folding body 102 and the second folding body 104 are folded relative to each other, the shape of some structures in the flexible screen 106 will change, that is, a bending area 1062 is formed. As for the connecting component 108 for connecting the two folding bodies, it includes two first plates 1082 and a second plate 1084. The second plate 1084 and the bending axis of the bending area 1062 are arranged correspondingly, that is, the second plate 1084 covers the center of the bending area 1062, and the two first plates 1082 are respectively located on both sides of the second plate 1084, and are arranged correspondingly to the opposite sides of the bending area 1062. When the first folding body 102 and the second folding body 104 are folded, the second plate 1084 will float up and down, that is, it will move in the direction from the inside to the outside of the electronic device 200, thereby achieving a certain avoidance effect on the folded flexible screen 106.
[0025] It should be emphasized that a second magnetic member 1104 is provided on the first plate member 1082 and the second plate member 1084, which can generate a magnetic attraction force with the first magnetic member 1102 on the flexible screen 106. When folding occurs, the second plate member 1084 will move downward, that is, move away from the flexible screen 106. Under the action of the magnetic force of the first magnetic member 1102 and the second magnetic member 1104, the part of the bending area 1062 in the flexible screen 106 will be attracted. The degree of free deformation of the flexible screen 106 is small, and a water drop angle can be formed more easily. The bending stress generated after the flexible screen 106 is bent can be significantly weakened, thereby reducing screen deformation. When unfolded, the crease can be weakened, greatly improving the user experience.
[0026] The electronic device 200 includes foldable mobile phones, foldable tablets, cameras, video cameras, notebooks and other devices with foldable screens.
[0027] Furthermore, if Figure 1As shown, it also includes: a first scroll 1122 and a second scroll 1124, which are respectively arranged at the ends of the first folding body 102 and the second folding body 104 away from the connecting component 108, and the two ends of the flexible screen 106 are respectively wound around the first scroll 1122 and the second scroll 1124, and extend to the second surface of the first folding body 102 and the second folding body 104, wherein the second surface is a surface opposite to the first surface; a tensioning device 114, which is arranged on the second surface of the first folding body 102 and / or the second folding body 104, and the two ends of the flexible screen 106 extending to the second surface are respectively connected to the tensioning device 114.
[0028] By respectively arranging two scrolls, namely, the first scroll 1122 and the second scroll 1124, at the two ends of the first folding body 102 and the second folding body 104, under the action of the two scrolls, a certain auxiliary effect can be played on the movement of the flexible screen 106 when folding or unfolding occurs. Specifically, the two ends of the flexible screen 106 respectively extend to the back side around the first scroll 1122 and the second scroll 1124, that is, extend to the second surface until connected to the tensioning device 114. When the first folding body 102 and the second folding body 104 are in a folded state, the part of the flexible screen 106 bent to the back side will move a certain distance toward the folding position, thereby ensuring the formation of the water drop angle of the bending area 1062. When unfolding, the flexible screen 106 will be stretched to both ends under the action of the tensioning device 114, thereby reducing the crease in the center.
[0029] The number of the tensioning device 114 may be one, and both ends of the tensioning device 114 are respectively connected to the two ends of the flexible screen 106 .
[0030] The number of the tensioning devices 114 may also be two, and each tensioning device 114 is connected to one end of the flexible screen 106 .
[0031] In one embodiment, Figure 1 As shown, the tensioning device 114 specifically includes: a first fixed block 1142, at least one first fixed block 1142 is respectively provided on the second surface of the first folding body 102 and the second folding body 104; a first elastic member 1144 and a first slider 1146, the first slider 1146 is arranged opposite to the first fixed block 1142, and the first slider 1146 moves in the direction from the first folding body 102 to the second folding body 104 in the unfolded state; the two ends of the first elastic member are respectively connected to the correspondingly arranged first fixed block and first slider.
[0032] In this embodiment, the tensioning device 114 mainly includes a first fixed block 1142, a first elastic member 1144 and a first slider 1146. The first fixed block 1142 is fixedly connected to the first folding body 102 and the second folding body 104. The first fixed block 1142 on each folding body is connected to the corresponding first slider 1146 through a first elastic member 1144. In the unfolded state, the screen will be tightened under the action of the first elastic member 1144, so that the crease in the middle bending area 1062 can be extended and straightened, thereby weakening the crease. In the folded state, the second plate 1084 will move downward, that is, move toward the back side, and the bending area 1062 of the flexible screen 106 is driven by the second plate 1084, so that the parts at both ends will move toward the middle.
[0033] The first elastic member 1144 is a spring.
[0034] In one embodiment, Figure 3 , Figure 4 and Figure 5 As shown, the tensioning device 114 specifically includes: correspondingly arranged magnetic columns 1150 and magnetic blocks 1154, at least one magnetic column 1150 is respectively arranged on the second surface of the first folding body 102 and the second folding body 104; the magnetic block 1154 is connected to the corresponding magnetic column 1150 through the second elastic member 1157, and the magnetic block 1154 moves in the direction from the first folding body to the second folding body in the unfolded state; the first driving member 1158 is transmission-connected to the magnetic column 1150, and the first driving member 1158 is used to drive the magnetic column 1150 to rotate so as to adjust the magnetic force between the magnetic column 1150 and the magnetic block 1154.
[0035] In this embodiment, the tensioning device 114 mainly includes a magnetic column 1150, a magnetic block 1154 and a first driving member 1158. The position of the magnetic column 1150 is fixed and is respectively fixedly connected to the first folding body 102 and the second folding body 104. The magnetic column 1150 and the magnetic block 1154 are connected by a second elastic member 1157. In the unfolded state, the screen will be tightened under the action of the second elastic member 1157, so that the fold in the middle bending area 1062 can be extended and straightened, thereby weakening the fold. In the folded state, the second plate 1084 will move downward, that is, move toward the back side, and the bending area 1062 of the flexible screen 106 will be driven by the second plate 1084, so that the parts at both ends will move toward the middle. On this basis, during the folding process, the first driving member will drive the magnetic column 1150 to rotate, so that the magnetic force between the magnetic block 1154 and the magnetic column 1150 is a repulsive force, which will assist in driving the flexible screen 106 to move toward the bending area 1062, making it easier to provide better support for the flexible screen 106 during the folding process.
[0036] The second elastic member 1157 is a spring.
[0037] Furthermore, the magnetic column 1150 specifically includes: a support tube 1151, which is transmission-connected to the first driving member; a first magnetic layer 1152 and a second magnetic layer 1153 with different polarities, which are arranged on the support tube 1151 along the circumference of the support tube 1151; wherein the first magnetic layer 1152 and the second magnetic layer 1153 are respectively located on two opposite sides of the support tube 1151.
[0038] The magnetic column 1150 mainly includes a support tube 1151 and two magnetic layers, namely a first magnetic layer 1152 and a second magnetic layer 1153. The support tube 1151 serves as a support body of the entire magnetic column 1150 and is directly connected to the first driving member. Under the action of the first driving member, the support tube 1151 will rotate. During the rotation, the first magnetic layer 1152 and the second magnetic layer 1153 will be arranged on opposite sides of the support tube 1151 along the circumference of the support tube 1151, that is, the first magnetic layer 1152 and the second magnetic layer 1153 respectively occupy 180° side walls of the support tube 1151.
[0039] It should be added that, since the polarities of the first magnetic layer 1152 and the second magnetic layer 1153 are different, when the first driving member drives the support cylinder 1151 to rotate, the magnetic field between the magnetic column 1150 and the magnetic block 1154 will change to achieve the conversion of attraction and repulsion.
[0040] Specifically, during the folding process, the magnetic force between the magnetic block 1154 and the magnetic column 1150 is a repulsive force, and during the unfolding process, the magnetic force between the magnetic block 1154 and the magnetic column 1150 is an attractive force.
[0041] Furthermore, the magnetic block 1154 specifically includes: a fixed base 1155 ; and a third magnetic layer 1156 , which is disposed on a side of the fixed base 1155 facing the magnetic column 1150 .
[0042] The magnetic block 1154 mainly includes a fixed base 1155 and a third magnetic layer 1156. The third magnetic layer 1156 is arranged on the side of the fixed base 1155 facing the magnetic column 1150. The fixed base 1155 will slide under the action of external force and magnetic force. The magnetism of the third magnetic layer 1156 is constant, so that the magnetic field generated by the third magnetic layer 1156 and the magnetic field generated by the first magnetic layer 1152 or the second magnetic layer 1153 will interact with each other, and finally generate attraction or repulsion on the magnetic block 1154.
[0043] Furthermore, the first driving member is used to drive the support tube 1151 to rotate in the folded state, so that the third magnetic layer 1156 is repelled and moves toward the end of the electronic device.
[0044] In the folded state, the first driving member rotates the supporting tube 1151 so that the third magnetic layer 1156 is subjected to repulsive force, thereby assisting in driving the flexible screen 106 to move toward the bending area 1062, which is more convenient for providing better support for the flexible screen 106 during the folding process.
[0045] In one embodiment, Figure 6 and Figure 7 As shown, the tensioning device 114 specifically includes: a first fixed block 1142, at least one first fixed block 1142 is respectively provided on the second surface of the first folding body 102 and the second folding body 104; a first elastic member 1144 and a first slider 1146, the first slider 1146 is arranged opposite to the first fixed block 1142, and the first slider 1146 moves in the direction from the first folding body 102 to the second folding body 104 in the unfolded state; the two ends of the first elastic member are respectively connected to the correspondingly arranged first fixed block and the first slider. In addition, a second driving member 1168 is also provided, which is transmission-connected to the first fixed block 1142, and the second driving member 1168 is used to drive the first fixed block 1142 to move toward the end of the first folding body 102 and the second folding body 104 away from the connecting assembly 108 in the folded state.
[0046] In this embodiment, the tensioning device 114 includes a first fixed block 1142, a first elastic member 1144, a first slider 1146 and a second driving member 1168. The first fixed block 1142 is arranged on the first folding body 102 and the second folding body 104. The first fixed block 1142 is connected to the first slider 1146 through the first elastic member 1144, and the first fixed block 1142 is transmission-connected to the first driving member 1148. Under the action of the second driving member 1168, the first fixed block 1142 will be driven to move.
[0047] In the unfolded state, the screen will be tightened under the action of the first elastic member 1144, so that the crease of the middle bending zone 1062 can be extended and straightened, and the crease will be weakened. In the folded state, the second plate 1084 will move downward, that is, move to the back side, and the bending zone 1062 of the flexible screen 106 is driven by the second plate 1084, so that the parts at both ends will move toward the middle. On this basis, during the folding process, the second driving member 1168 will drive the first fixed block 1142 to move, causing the screen to slide, and will assist in driving the flexible screen 106 to move toward the bending zone 1062, which is more convenient for providing a better support effect on the flexible screen 106 during the folding process.
[0048] The second driving member 1168 may be a linear motor or a screw mechanism, as long as it can drive the first fixed block 1142 to translate after rotating.
[0049] Furthermore, the second plate 1084 is connected to the bending center axis 118 of the bending zone 1062 , and the second plate 1084 drives the bending zone 1062 to move in a direction from the inside to the outside of the electronic device 200 .
[0050] By connecting the second plate 1084 to the bending center axis 118 of the bending zone 1062, the second plate 1084 can drive the bending zone 1062 to move up and down, thereby achieving continuous support for the flexible screen 106, reducing the possibility of free deformation, and weakening the impact of creases.
[0051] Furthermore, the first magnetic member 1102 is a magnetizable steel sheet, and the second magnetic member 1104 is a magnet.
[0052] By restricting the first magnetic part 1102 and the second magnetic part 1104, the first magnetic part 1102 is a steel sheet that can be directly embedded in the flexible screen 106 as a support plate for the flexible screen 106, and can be magnetized at the same time. Under the action of the second magnetic part 1104, it will exert a continuous suction effect on the flexible screen 106, so that when folded, it will force the bending area 1062 of the flexible screen 106 to form a water drop angle, reduce the degree of freedom of the flexible screen 106 when bending, and also reduce the crease.
[0053] In a specific embodiment, a folding screen unfolding mechanism with reduced creases is provided, which mainly includes a flexible screen (i.e., flexible screen 106), a screen scroll (i.e., a first scroll 1122 and a second scroll 1124), a screen fixing block (i.e., a first slider 1146), a constant force spring (i.e., a first elastic member 1144), a main upper fixing block (i.e., the first fixing block 1142), a hinge assembly, and left and right door panels (i.e., the first panel 1082) and a floating middle panel (i.e., the second panel 1084) in the hinge assembly.
[0054] like Figure 1As shown, this embodiment first utilizes the up and down movement characteristics of the floating middle plate to connect the bending midpoint of the screen with the floating middle plate (the connection method can be a single method or a combination of welding, gluing, screwing or magnetic connection); the left and right door panels of the hinge assembly and the middle floating door panel are fixed with door panel magnetic layers close to the screen surface to absorb the screen steel sheet; secondly, scrolls are added to the main upper ends on both sides of the folding machine so that the screen has a movable area at the main upper and lower parts; at the same time, a screen fixing block is fixed to the tail of the lower part of the screen, and the fixing block is connected to a constant force spring, and the other end of the constant force spring is connected to the main upper fixing Block; sliding grooves for screen fixing blocks are designed at the upper and lower parts of the main frame; when the screen is unfolded, the screen is tightened by the constant force spring, so that the bending risk area can be extended and straightened, which plays a certain role in repairing creases; when the screen is folded, the floating middle plate moves downward, and the middle part of the screen is stretched by the floating middle plate to make the screen slide through the stretching fixed block, so as to meet the length change requirement when the screen is bent. At the same time, the left and right door panels and the floating middle plate attract the middle bending area of the screen through the magnetic attraction, so as to maintain the formation of the bending water drop angle, weaken the bending stress caused by the bending deformation of the screen, and reduce the deformation of the screen.
[0055] Furthermore, if Figure 3 As shown, an auxiliary driving assembly (ie, a magnetic block 1154, a magnetic column 1150 and a first driving member) is provided at the lower tail of the screen. A screen fixing block is fixed at the tail of the lower part of the screen, and the fixing block is connected to a constant force spring, and the other end of the constant force spring is connected to a cylindrical magnetic block, and the cylindrical magnetic block is connected to a motor assembly; a screen fixing block sliding groove is designed at the upper and lower parts of the main body; when the screen is unfolded, the screen is tightened by the spring elasticity and the magnetic attraction between the magnetic block and the screen fixing block, so that the bending risk area can be extended and straightened, which plays a certain role in repairing creases; when the screen is folded, the floating middle plate moves downward, and the middle part of the screen is stretched by the floating middle plate. At the same time, the motor (i.e., magnetic part) of the auxiliary drive assembly drives the cylindrical magnetic block (i.e., magnetic column 1150) to rotate, so that the magnetic block (i.e., magnetic block 1154) repels the screen fixing block, and assists in driving the screen to slide outward to meet the length change requirement when the screen is bent. At the same time, the left and right door panels and the floating middle plate attract the middle bending area 1062 of the screen through magnetic attraction to promote the formation of a bending water drop angle, weaken the bending stress caused by the bending deformation of the screen, and reduce the deformation of the screen.
[0056] Or, if Figure 6As shown, an auxiliary driving assembly (i.e., the second driving member 1168) is provided at the lower tail of the screen, a screen fixing block is fixed at the lower tail of the screen, the fixing block is connected to the spring group, the other end of the buffer spring group is connected to the shaft connecting block (i.e., the first fixing block 1142), the shaft connecting block is fixed to the external shaft of the motor, and is driven by the linear motor assembly (i.e., the second driving member 1168); a screen fixing block sliding groove is designed at the upper and lower parts of the main body; when the screen is unfolded, the screen is tightened by the action of the spring, so that the bending risk area can be extended and straightened, which plays a certain role in repairing creases; when the screen is folded, the floating middle plate moves downward, and the middle part of the screen is stretched by the floating middle plate. At the same time, the linear motor of the auxiliary driving assembly pushes the shaft connecting block to slide outward, prompting the screen to slide, so as to meet the length change requirement when the screen is bent. At the same time, the left and right door panels and the floating middle plate attract the middle bending area of the screen through magnetic attraction to prompt the formation of the bending water drop angle, weaken the bending stress caused by the bending deformation of the screen, and reduce the deformation of the screen.
[0057] According to an embodiment of the electronic device of the present application, by arranging a first plate and a second plate having magnetism on the back side of the flexible screen, a supporting effect can be provided for the flexible screen when it is folded, thereby limiting the range of its free deformation and reducing creases.
