Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and specifically relates to an electronic device. Background Technology

[0002] Currently, the flexible screen of foldable electronic devices is set on the frame. The flexible screen folds or unfolds as the frame moves. Its most obvious drawback is that a noticeable crease will be generated in the bending area of ​​the flexible screen, and the crease will become more and more obvious as the number of times it is opened and closed increases. Summary of the Invention

[0003] This application aims to provide an electronic device that at least addresses the problem of how to improve the creases of flexible screens.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] This application provides an electronic device, comprising: a hinge assembly including a support and a floating plate movably connected to the support; a first body and a second body, the first body and the second body being rotatably connected to the hinge assembly respectively, so that the electronic device can switch between a folded state and an unfolded state; a flexible screen connected to the first body and the second body, the flexible screen including a folding area, and the floating plate being correspondingly disposed with respect to the folding area; and a drive assembly connected to the floating plate to drive the floating plate to move relative to the support, wherein when the electronic device is in the unfolded state, the drive assembly drives the floating plate to support the folding area.

[0006] In embodiments of this application, the electronic device includes a hinge assembly, a first body, a second body, a flexible screen, and a driving assembly. The hinge assembly includes a support and a floating plate, with the floating plate movably connected to the support, allowing the floating plate to move relative to the support. The first body and the second body are rotatably connected to the hinge assembly, thereby enabling the electronic device to have an unfolded state and a folded state. The flexible screen is disposed on the first and second bodies, and can fold or unfold with the movement of the first and second bodies, making the electronic device easy to carry while maintaining a large display screen. The driving assembly is connected to the floating plate and drives the floating plate to move relative to the support. Thus, when the electronic device is in the unfolded state, the driving assembly causes the floating plate to rise and support the folded area, improving the crease problem in the folded area. Through the interaction between magnetic components, this method saves time and effort and has a lower manufacturing cost.

[0018] The following is combined Figures 1-3 An electronic device according to an embodiment of the present invention is described.

[0019] like Figure 1 and Figure 2 As shown, an electronic device according to some embodiments of the present invention includes: a hinge assembly 1, including a support 10 and a floating plate 12 movably connected to the support 10; a first body 6 and a second body 7, the first body 6 and the second body 7 being rotatably connected to the hinge assembly 1 respectively, so that the electronic device can switch between a folded state and an unfolded state; a flexible screen 4, the flexible screen 4 being connected to the first body 6 and the second body 7, the flexible screen 4 including a folding area 40, the floating plate 12 being correspondingly disposed with respect to the folding area 40; and a drive assembly 5, connected to the floating plate 12, to drive the floating plate 12 to move relative to the support 10, wherein when the electronic device is in the unfolded state, the drive assembly 5 drives the floating plate 12 to support the folding area 40.

[0020] In embodiments of this application, the electronic device includes a hinge assembly 1, a first body 6, a second body 7, a flexible screen 4, and a driving assembly 5. The hinge assembly 1 includes a support 10 and a floating plate 12, the floating plate 12 being movably connected to the support 10, allowing the floating plate 12 to move relative to the support 10. The first body 6 and the second body 7 are rotatably connected to the hinge assembly 1, thereby enabling the electronic device to have an unfolded state and a folded state. The flexible screen 4 is disposed on the first body 6 and the second body 7, and can fold or unfold with the movement of the first body 6 and the second body 7, making the electronic device easy to carry while maintaining a large display screen. The driving assembly 5 is connected to the floating plate 12 and drives the floating plate 12 to move relative to the support 10. Thus, when the electronic device is in the unfolded state, the driving assembly 5 causes the floating plate 12 to rise and support the folding area 40, improving the crease problem of the folding area 40. Through the interaction between magnetic components, this method saves time and effort and has a low manufacturing cost.

[0021] It is understandable that the folding area 40 is positioned corresponding to the hinge assembly 1. When folding the electronic device, the folding area 40 bends, and after repeated bending, creases are easily formed, causing the folding area 40 to dent downwards. Therefore, in the unfolded state, supporting the folding area 40 with a floating plate can improve the crease problem. In specific applications, the first area of ​​the flexible screen 4 is laid on one side of the first main body 6, the second area of ​​the flexible screen 4 is laid on one side of the second main body 7, and the folding area 40 is located between the first and second areas.

[0022] According to one embodiment of this application, the hinge assembly 1 further includes: a first swing arm 2, one end of which is connected to the first body 6, and the other end of which faces the floating plate 12; a second swing arm 3, one end of which is connected to the second body 7, and the other end of which faces the floating plate 12. The first swing arm 2 and the second swing arm 3 are respectively rotatably connected to the bracket 10 so that the first body 6 and the second body 7 rotate relative to the hinge assembly 1. A portion of the drive assembly 5 is disposed in at least one of the first swing arm 2 and the second swing arm 3, wherein a portion of the drive assembly 5 is disposed in the floating plate 12. During the rotation of the first swing arm 2 and the second swing arm 3 relative to the bracket 10, the portion of the drive assembly 5 disposed in at least one of the first swing arm 2 and the second swing arm 3 cooperates with the portion of the drive assembly 5 disposed in the floating plate 12 to drive the floating plate 12 to rise toward the folding area 40.

[0023] In this embodiment, the hinge assembly 1 further includes a first swing arm 2 and a second swing arm 3. The first swing arm 2 and the second swing arm 3 are rotatably connected to the bracket 10, and one end of the first swing arm 2 is connected to the first main body 6, while the other end faces the floating plate 12. One end of the second swing arm 3 is connected to the second main body 7, while the other end faces the floating plate 12. When the first main body 6 and the second main body 7 rotate relative to the bracket 10, they drive the first swing arm 2 and the second swing arm 3 to move, causing the distance between the end of the first swing arm 2 facing the floating plate 12 and the end of the second swing arm 3 facing the floating plate 12 and the floating plate 12 to change. Since a part of the driving assembly 5 is disposed on at least one of the first swing arm 2 and the second swing arm 3, and the other part is disposed on the floating plate 12, during the movement of the first swing arm 2 and the second swing arm 3, the two parts of the driving assembly 5 cooperate to make the floating plate 12 rise towards the folding area 40 to support the folding area 40 and improve the crease problem of the flexible screen 4.

[0024] In specific applications, during the process of switching the electronic device from a folded state to an unfolded state, a portion of the drive component 5 provided in at least one of the first swing arm 2 and the second swing arm 3 cooperates with a portion of the drive component 5 provided on the floating plate 12, causing the floating plate 12 to rise towards the folding area 40 to support the folding area 40; during the process of switching the electronic device from an unfolded state to a folded state, a portion of the drive component 5 cooperates with a portion of the drive component 5 provided on the floating plate 12, causing the floating plate 12 to descend.

[0025] According to one embodiment of this application, the driving component 5 includes: a first magnetic element 50 and a second magnetic element 52. The first magnetic element 50 is disposed on the floating plate 12, and the second magnetic element 52 is disposed on at least one of the first swing arm 2 and the second swing arm 3. When the electronic device is in the unfolded state, the second magnetic element 52 is located on the side of the first magnetic element 50 away from the flexible screen 4. The second magnetic element 52 and the first magnetic element 50 are disposed opposite to each other and repel each other, so that the floating plate 12 supports the folding area 40. When the electronic device is in the folded state, the first magnetic element 50 and the second magnetic element 52 are disposed in a staggered manner.

[0026] In this embodiment, the driving component 5 includes a first magnetic element 50 and a second magnetic element 52. The first magnetic element 50 is disposed on the floating plate 12, and the second magnetic element 52 is disposed on at least one of the first swing arm 2 and the second swing arm 3. Through the cooperation of the first magnetic element 50 and the second magnetic element 52, the floating plate 12 moves relative to the support 10. When the electronic device is in the unfolded state, the second magnetic element 52 is located on the side of the first magnetic element 50 away from the flexible screen 4 and repels the first magnetic element 50, thereby driving the floating plate 12 to support the folding area 40 through the repulsive force. When the electronic device is in the folded state, the first magnetic element 50 and the second magnetic element 52 are staggered, reducing the repulsive force between the first magnetic element 50 and the second magnetic element 52. As a result, the floating plate 12 is no longer driven by a force in the direction of the folding area 40, causing the floating plate 12 to descend relative to the folding area 40.

[0027] like Figure 1 and Figure 2 As shown, according to one embodiment of this application, the electronic device further includes a reset member 54, which is connected to the bracket 10 and the floating plate 12. During the process of switching the electronic device from an unfolded state to a folded state, the reset member 54 drives the floating plate 12 away from the folding area 40.

[0028] In this embodiment, the electronic device also includes a reset member 54, which is connected to the bracket 10 and the floating plate 12. The reset member 54 is used to drive the floating plate 12 away from the folding area 40 during the process of switching the electronic device to the folding state, so as to ensure that the electronic device folds smoothly and avoid the electronic device folding backward due to the obstruction of the floating plate 12.

[0029] In practical applications, in the folded state, the first magnetic element 50 and the second magnetic element 52 are staggered, so the second magnetic element 52 no longer generates a driving force for the first magnetic element 50 to move toward the folding area 40, or the driving force is small, which makes it easier for the reset element 54 to drive the floating plate 12 to move away from the folding area 40.

[0030] That is, in the unfolded state, the floating plate 12 is driven to support the folding area 40 under the magnetic force of the first magnetic element 50 and the second magnetic element 52; in the folded state, the floating plate 12 is moved away from the folding area 40 under the action of the reset element 54, so as to ensure the reliability of the folding process of the electronic device.

[0031] like Figure 1 and Figure 2 As shown, according to one embodiment of this application, the reset member 54 includes a third magnetic member 540 and a fourth magnetic member 542. The third magnetic member 540 is disposed on the bracket 10, and the fourth magnetic member 542 is disposed on the floating plate 12. The third magnetic member 540 is located on the side of the fourth magnetic member 542 away from the folding area 40. The third magnetic member 540 and the fourth magnetic member 542 are disposed opposite to each other and attract each other.

[0032] In this embodiment, the reset member 54 includes a third magnetic member 540 connected to the bracket 10 and a fourth magnetic member 542 connected to the floating plate 12. The third magnetic member 540 is located on the side of the fourth magnetic member 542 away from the folding area 40, and the fourth magnetic member 542 is attracted to the third magnetic member 540. In this way, through the action of the third magnetic member 540 and the fourth magnetic member 542, the floating plate 12 can be driven to move away from the folding area 40, thereby ensuring the reliability of the folding of the electronic device.

[0033] It should be noted that the first magnetic component 50 and the second magnetic component 52 repel each other with a magnetic repulsion force of Fc, while the magnetic attraction between the third magnetic component 540 and the fourth magnetic component 542 is Fx. In the unfolded state, the magnetic repulsion force Fc is greater than the magnetic attraction force Fx, at which point the floating plate 12 is lifted up, serving to support the folding area 40.

[0034] That is, part of the drive assembly 5 is set on the bracket 10, the first swing arm 2 and the second swing arm 3, and the other part is set on the floating plate 12. Through the cooperation of the part of the drive assembly 5 set on the bracket 10, the first swing arm 2 and the second swing arm 3 and the part of the drive assembly 5 set on the floating plate 12, the floating plate 12 can switch between rising towards the folding area 40 and falling away from the folding area 40 relative to the bracket 10.

[0035] During the transition from the unfolded state to the folded state of the first swing arm 2 and the second swing arm 3, the positions of the first magnetic component 50 and the second magnetic component 52 gradually shift apart, the magnetic repulsion force Fc decreases, and the floating plate 12 moves downward, preventing the flexible screen 4 from folding backward. At the same time, the distance between the first magnetic component 50 and the second magnetic component 52 becomes closer, the magnetic attraction force Fx increases, and the downward movement of the floating plate 12 is accelerated, making room for the bending of the flexible screen 4, avoiding the flexible screen 4 from being squeezed, and improving the crease.

[0036] In specific applications, the first magnetic component 50, the second magnetic component 52, the third magnetic component 540, and the fourth magnetic component 542 are permanent magnets.

[0037] According to one embodiment of this application, the reset member 54 includes: an elastic member located on the side of the floating plate 12 away from the folding area 40; one end of the elastic member is connected to the bracket 10 and the other end is connected to the floating plate 12, and the elastic member is in a deformed state in the unfolded state.

[0038] In this embodiment, the reset member 54 includes an elastic member, which is connected to the floating plate 12 and the support 10. In the unfolded state, under the action of the first magnetic member 50 and the second magnetic member 52, the floating plate 12 rises to support the folding area 40. During the process of the first support part and the second support part switching from the unfolded state to the folded state, the force between the second magnetic member 52 and the first magnetic member 50 is reduced, and then the floating plate 12 is pulled downward under the action of the elastic member to avoid the flexible screen 4 from folding backward.

[0039] Understandably, in the unfolded state, the first magnetic component 50 and the second magnetic component 52 repel each other, with a magnetic repulsion force of Fc. The elastic component is in a deformed state, and the elastic component exerts a pulling force of Ft on the floating plate 12. In the unfolded state, the magnetic repulsion force Fc is greater than the pulling force Ft. At this time, the floating plate 12 is lifted up, which serves to support the folding area 40.

[0040] During the transition from the unfolded state to the folded state of the first swing arm 2 and the second swing arm 3, the positions of the first magnetic component 50 and the second magnetic component 52 gradually shift, the magnetic repulsion force Fc decreases, and the floating plate 12 moves downward, preventing the flexible screen 4 from folding backward. At the same time, under the action of the elastic component, the floating plate 12 is pulled downward, accelerating the downward movement of the floating plate 12, making room for the bending of the flexible screen 4, avoiding the flexible screen 4 from being squeezed, and improving the crease.

[0041] like Figure 1 As shown, according to one embodiment of this application, the floating plate 12 includes: a plate body 122, which is correspondingly disposed with respect to the folding area 40; and a limiting post 124, which is disposed on the side of the plate body 122 away from the folding area 40. The bracket 10 is provided with a sinkhole 100, and a part of the limiting post 124 is disposed in the sinkhole 100 and is movably connected to the sinkhole 100.

[0042] In this embodiment, the floating plate 12 includes a plate body 122 and a limiting post 124. The plate body 122 is correspondingly disposed with respect to the folding area 40 and is used to support the folding area 40, thereby improving the crease problem of the folding area 40. The support 10 is provided with a recess 100, and the limiting post 124 is disposed within the recess 100, which guides the movement of the floating plate 12, ensuring the position of the floating plate 12 relative to the support 10. This prevents positional shift of the floating plate 12 during its vertical movement and improves the reliability of crease improvement using the floating plate 12.

[0043] In practical applications, the limiting post 124 can slide relative to the settling tank 100.

[0044] like Figure 1 As shown, according to one embodiment of this application, at least two first magnetic elements 50 are provided on the plate 122, and the at least two first magnetic elements 50 are located on both sides of the limiting post 124; when the first swing arm 2 and the second swing arm 3 are both provided with second magnetic elements 52, the at least two first magnetic elements 50 are respectively corresponding to the second magnetic elements 52 on the first swing arm 2 and the second magnetic elements 52 on the second swing arm 3.

[0045] In this embodiment, at least two first magnetic elements 50 are provided on the plate 122, and second magnetic elements 52 are provided on both the first swing arm 2 and the second swing arm 3. Furthermore, the at least two first magnetic elements 50 on the plate 122 correspond to the second magnetic elements 52 on the first swing arm 2 and the second magnetic elements 52 on the second swing arm 3, respectively, thereby increasing the magnetic repulsion between the second magnetic elements 52 and the first magnetic elements 50, and thus improving the driving force on the floating plate 12. Simultaneously, the at least two first magnetic elements 50 are located on both sides of the limiting post 124. Under the drive of the first magnetic elements 50 and the second magnetic elements 52, the two sides of the floating plate 12 can maintain balance, thereby ensuring the supporting effect of the floating plate 12 on the folding area 40.

[0046] In specific applications, the second magnetic element 52 on the first swing arm 2 is located at the end of the first swing arm 2, and the second magnetic element 52 on the second swing arm 3 is located at the end of the second swing arm 3.

[0047] like Figure 1 As shown, according to one embodiment of this application, when the reset member 54 includes a third magnetic member 540 and a fourth magnetic member 542, the end of the limiting post 124 away from the plate 122 is provided with a fourth magnetic member 542, and the fourth magnetic member 542 on the limiting post 124 is correspondingly provided with the third magnetic member 540 on the bracket 10.

[0048] In this embodiment, when the reset member 54 includes a third magnetic member 540 and a fourth magnetic member 542, the end of the limiting post 124 away from the plate 122 is provided with a fourth magnetic member 542, and the fourth magnetic member 542 on the limiting post 124 is correspondingly provided with the third magnetic member 540 on the bracket 10, thereby driving the floating plate 12 to move downward by the adsorption force of the fourth magnetic member 542 and the third magnetic member 540.

[0049] In practical applications, the third magnetic element 540 is set at the bottom of the sink 100, and the end of the limiting post 124 with the fourth magnetic element 542 extends into the sink 100.

[0050] According to one embodiment of this application, along the movement direction of the limiting post 124, the depth of the sink 100 is less than the length of the limiting post 124.

[0051] In this embodiment, along the movement direction of the limiting post 124, the depth of the sink 100 is less than the length of the limiting post 124. Therefore, in the folded state, there is a certain gap between the lower surface of the plate 122 and the sink 100. Thus, during the process of switching from the folded state to the unfolded state, the first swing arm 2 and the second swing arm 3 can move to the lower surface of the plate 122, so that the repulsive force between the second magnetic element 52 and the first magnetic element 50 gradually increases, thereby overcoming the pulling force of the reset element 54 on the floating plate 12, and causing the floating plate 12 to rise.

[0052] like Figure 2 As shown, according to one embodiment of this application, the bracket 10 has a first channel 102 in the middle, the folding area 40 covers the first channel 102, the floating plate 12 is disposed in the first channel 102 and can move in the first channel 102; in the folded state, at least a portion of the folding area 40 extends into the first channel 102.

[0053] In this embodiment, a first channel 102 is provided in the middle of the support 10, and a floating plate 12 is disposed in the first channel 102 and can move within the first channel 102. The folding area 40 covers the first channel 102. In the unfolded state, the floating plate 12 moves toward the top of the first channel 102 to support the folding area 40. In the folded state, the floating plate 12 moves away from the folding area 40, and at least a portion of the folding area 40 extends into the first channel 102, which can prevent the folding area 40 from stacking and thus improve the crease condition of the folding area 40.

[0054] In a specific application, the settling tank 100 is located below the first channel 102 and is connected to the first channel 102.

[0055] like Figure 1 and Figure 2As shown, according to one embodiment of this application, the bracket 10 is further provided with a second channel 104 and a third channel 106. The second channel 104 and the third channel 106 are located on both sides of the first channel 102 and communicate with the first channel 102. The first swing arm 2 is movably connected to the second channel 104, and the second swing arm 3 is movably connected to the third channel 106. When the electronic device is in a folded state, the first swing arm 2 is located at the end of the second channel 104 away from the first channel 102, and the second swing arm 3 is located at the end of the third channel 106 away from the first channel 102. When the electronic device is in an unfolded state, the ends of the first swing arm 2 and the second swing arm 3 extend into the first channel 102.

[0056] In this embodiment, the support 10 is further provided with a second channel 104 and a third channel 106. The second channel 104 and the third channel 106 are located on both sides of the first channel 102 and communicate with the first channel 102. Specifically, the first swing arm 2 is movably connected to the second channel 104, and the second swing arm 3 is movably connected to the third channel 106. When the first swing arm 2 and the second swing arm 3 are folded or unfolded relative to the support 10, the first swing arm 2 slides in the second channel 104, and the second swing arm 3 slides in the third channel 106. The second channel 104 guides the movement of the first swing arm 2, and the third channel 106 guides the movement of the second swing arm 3, ensuring the reliability of the movement of the first swing arm 2 and the second swing arm 3.

[0057] In the folded state, the first swing arm 2 is located at the end of the second channel 104 away from the first channel 102, and the second swing arm 3 is located at the end of the third channel 106 away from the first channel 102. During the transition from the folded state to the unfolded state, the first swing arm 2 gradually moves closer to the first channel 102 from the second channel 104, and the second swing arm 3 gradually moves closer to the first channel 102 from the third channel 106. The second magnetic component 52 gradually moves closer to the first magnetic component 50, causing the magnetic repulsion between the second magnetic component 52 and the first magnetic component 50 to gradually increase, thereby driving the floating plate 12 to rise to support the folding area 40. During the transition from the unfolded state to the folded state, the first swing arm 2 gradually moves away from the first channel 102, the second swing arm 3 gradually moves away from the first channel 102, and the second magnetic component 52 gradually moves away from the first magnetic component 50, causing the magnetic repulsion between the first magnetic component 50 and the second magnetic component 52 to gradually decrease. Under the action of the reset component 54, the floating plate 12 moves down to move away from the folding area 40, ensuring that the electronic device can be folded smoothly.

[0058] Specifically, the first swing arm 2 is slidably connected to the second channel 104, and the second swing arm 3 is slidably connected to the third channel 106.

[0059] It should be noted that electronic devices include mobile phones, tablets, or wearable devices.

[0060] In specific applications, such as Figure 1 and Figure 2 As shown, the electronic device includes a hinge assembly 1, a first body 6, a second body 7, a drive assembly 5, and a flexible screen 4. The hinge assembly 1 includes a bracket 10, a floating plate 12, a first swing arm 2, and a second swing arm 3. A first magnetic element 50 is fixed to the bottom of the floating plate 12, and a second magnetic element 52 with the same magnetism as the first magnetic element 50 on the floating plate 12 is fixed to the top of the first and second swing arms 2 and 3. A third magnetic element 540 with the opposite magnetism to the fourth magnetic element 542 is fixed to the bracket 10. In the unfolded state, the floating plate 12 is lifted by the magnetic repulsion between the floating plate 12 and the first and second swing arms 2 and 3, thus supporting the flexible screen 4. When the first swing arm 2 and the second swing arm 3 are closed, the first magnetic component 50 and the second magnetic component 52 are misaligned, and the supporting force on the floating plate 12 gradually weakens and disappears. The magnetic attraction between the bracket 10 and the floating plate 12 gradually increases, providing space for the flexible screen 4 to bend, thereby improving the crease. When the first swing arm 2 and the second swing arm 3 are unfolded, the magnetic repulsion between the first swing arm 2, the second swing arm 3 and the floating plate 12 gradually increases, pushing the floating plate 12 upward to press against the indentation of the flexible screen 4, thereby improving the crease.

[0061] Specifically, such as Figure 3 As shown, a recessed groove 100 is provided on the bracket 10, and a limiting post 124 extends from the bottom of the floating plate 12. A first magnetic component 50 (N1) and a fourth magnetic component 542 (N3) with N pole magnetism are fixed at the bottom of the floating plate 12. A second magnetic component 52 (N2) with N pole magnetism is fixed at the top of the first swing arm 2 and the second swing arm 3 on both sides. A third magnetic component 540 (S1) with S pole magnetism is provided on the bracket 10. Grooves are provided at the positions of the first magnetic component 50, the second magnetic component 52, the third magnetic component 540 and the fourth magnetic component 542. The first magnetic component 50, the second magnetic component 52, the third magnetic component 540 and the fourth magnetic component 542 are fixed in the grooves by dispensing glue.

[0062] The magnetic repulsion between the first magnetic element 50 (N1) and the second magnetic element 52 (N2) is Fc, and the magnetic attraction between the fourth magnetic element 542 (N3) and the third magnetic element 540 (S1) is Fx. In the unfolded state, the magnetic repulsion Fc is greater than the magnetic attraction Fx, and at this time the floating plate 12 is lifted up to support the flexible screen 4.

[0063] During the bending process of the flexible screen 4, the positions of the first magnetic component 50 (N1) and the second magnetic component 52 (N2) gradually shift, the magnetic repulsion force Fc decreases, and the floating plate 12 moves downward, preventing the flexible screen 4 from folding backward. At the same time, the distance between the fourth magnetic component 542 (N3) and the third magnetic component 540 (S1) becomes closer, the magnetic attraction force Fx increases, and the downward movement of the floating plate 12 is accelerated, making room for the bending of the flexible screen 4, avoiding the flexible screen 4 from being squeezed, and improving the crease.

[0064] During the unfolding of the flexible screen 4, the distance between the first magnetic component 50 (N1) and the second magnetic component 52 (N2) gradually decreases, the magnetic repulsion force Fc gradually increases, and the magnetic attraction force Fx gradually decreases. Under the action of the magnetic repulsion force, the floating plate 12 moves upward and supports the concavity of the folding area 40 of the flexible screen 4, thereby improving the crease.
