Description

Technical Field

[0001] The present application relates to the technical field of foldable electronic products, and in particular to an electronic device. Background Art

[0002] With the continuous development of portable electronic devices such as mobile phones, technological advancements, and market demand for electronic devices, the application of foldable electronic devices is becoming increasingly widespread. Traditional foldable electronic devices include a first housing, a second housing, a folding mechanism, and a flexible screen. When the electronic device is closed, the first and second housings touch, and an air gap of a certain width exists between the flat areas of the flexible screen. The air in this gap blocks the heat conduction path between the first and second housings, resulting in low heat conduction efficiency between the first and second housings and poor heat distribution capabilities of foldable electronic devices. Utility Model Content

[0003] The present application provides an electronic device with high heat conduction efficiency and good heat distribution capability.

[0004] In the first aspect, the present application provides an electronic device. The electronic device includes a first shell, a second shell, a folding mechanism and a display module. The folding mechanism connects the first shell and the second shell, and the folding mechanism can make the first shell and the second shell relatively unfolded and folded; the display module includes a first display area, a second display area and a third display area arranged in sequence along the first direction, the first display area is fixedly connected to the first shell, the third display area is fixedly connected to the second shell, and the second display area is arranged opposite to the folding mechanism. The first direction is the direction in which the first shell points to the second shell when the electronic device is in a flattened state; when the electronic device is in a flattened state, the top surface of the first display area and the top surface of the third display area are both higher than the top surface of the third display area in the second direction. The top surface of the first shell and the top surface of the second shell, the second direction is different from the first direction; when the electronic device is in a closed state, the top surface of the first display area and the top surface of the third display area are in contact, and the second display area is bent; the first shell includes a first frame, a first middle plate and a first flexible member, the first frame is fixedly connected to the periphery of the first middle plate, the first display area is fixedly connected to the first middle plate, and the first display area is spaced apart from the first frame, and the second direction is the direction in which the first middle plate points to the first display area when the electronic device is in a flattened state; the first flexible member is fixedly connected to the first frame and / or the first middle plate, and at least part of the first flexible member is located between the first display area and the first frame.

[0005] It can be understood that by fixedly connecting the first display area to the first shell and the third display area to the second shell, the relative expansion and folding movements between the first display area and the third display area can be accurately controlled when the first shell and the second shell are relatively expanded or folded, so that the folding process and movement form of the display module are controllable and the reliability is high.

[0006] It can be understood that by setting up that when the electronic device is in a closed state, the top surface of the first display area and the top surface of the third display area can contact each other, thereby making the heat conduction area between the first shell and the second shell larger, the heat conduction path more continuous, and the heat conduction path shorter, thereby making the heat conduction speed between the first shell and the second shell faster, the heat conduction efficiency higher, and the heat balance ability of the electronic device stronger.

[0007] It can be understood that the first display area and the first frame are spaced apart, and at least part of the first flexible member is located between the first display area and the first frame. There is a certain space for movement between the first display area and the first flexible member. When the display module is unfolded or folded with the electronic device, the first display area is not likely to collide with the first flexible member, and the first display area is not likely to be damaged, thereby ensuring that the display module has better reliability.

[0008] Therefore, this implementation provides an electronic device that can improve both heat distribution capability and reliability.

[0009] In one possible implementation, the second shell includes a second frame, a second middle plate and a second flexible member, the second frame is fixedly connected to the periphery of the second middle plate, the third display area is fixedly connected to the second middle plate, and the third display area is spaced apart from the second frame; the second flexible member is fixedly connected to the second frame and / or the second middle plate, and at least part of the second flexible member is located between the third display area and the second frame.

[0010] It can be understood that the third display area is spaced apart from the second frame, and at least part of the second flexible member is located between the third display area and the second frame. There is a certain space for movement between the third display area and the second flexible member. When the display module is unfolded or folded with the electronic device, the third display area is not likely to collide with the second flexible member.

[0011] In one possible implementation, the first frame includes a first sub-edge, a second sub-edge and a third sub-edge, the second sub-edge connects the first sub-edge and the third sub-edge, and the first sub-edge and the third sub-edge are arranged opposite to each other; the first flexible member includes a first part, a second part and a third part, the second part connects the first part and the third part, and the first part and the third part are arranged opposite to each other; the first part is located between the first sub-edge and the first display area, the second part is located between the second sub-edge and the first display area, and the third part is located between the third sub-edge and the first display area.

[0012] It can be understood that, on the one hand, the first flexible member can cover most of the gap between the first display area and the first frame, so that when the display module is unfolded or folded with the electronic device, the first display area will not collide with the first flexible member; on the other hand, the first flexible member makes the gap between the first display area and the first frame smaller, which is conducive to improving the appearance of the electronic device.

[0013] In a possible implementation, the top surface of the first shell is the top surface of the first frame.

[0014] It can be understood that when the electronic device is in a flat state, the top surface of the first display area is higher than the top surface of the first frame; when the electronic device is in a closed state, the top surface of the first display area can be in contact with the top surface of the third display area, and the heat conduction area between the first shell and the second shell is larger and the heat conduction path is more continuous. Therefore, the heat conduction speed between the first shell and the second shell is faster and the heat conduction efficiency is higher, and the electronic device has a stronger heat distribution capacity.

[0015] In a possible implementation, the top surface of the first shell is the top surface of the first flexible member.

[0016] It can be understood that when the electronic device is in a flat state, the top surface of the first display area is higher than the top surface of the first flexible part; when the electronic device is in a closed state, the top surface of the first display area can be in contact with the top surface of the third display area, and the heat conduction area between the first shell and the second shell is larger and the heat conduction path is more continuous. Therefore, the heat conduction speed between the first shell and the second shell is faster and the heat conduction efficiency is higher, and the electronic device has a stronger heat distribution capacity.

[0017] In a possible implementation, the first display area is spaced apart from a side surface of the first flexible member close to the first display area, and a first gap is formed.

[0018] It is understandable that the first gap allows a certain space for movement between the first display area and the first flexible member, so that the first display area will not collide with the first flexible member when the display module is unfolded or folded with the electronic device.

[0019] In a possible implementation, the third display area is spaced apart from a side surface of the second flexible member close to the third display area, and a second gap is formed.

[0020] It is understandable that the second gap allows a certain space for movement between the third display area and the second flexible member, so that the third display area is unlikely to collide with the second flexible member when the display module is unfolded or folded with the electronic device.

[0021] In one possible implementation, the display module includes a display main layer and a protective layer arranged in sequence along the second direction, and the protective layer is located on the side of the display main layer away from the first shell and the second shell; when the electronic device is in a flattened state, the top surface of the protective layer is higher than the top surface of the first shell and the top surface of the second shell.

[0022] It is understandable that when the electronic device is in a closed state, the first shell and the second shell can be close to each other, the top surface of the first frame and the top surface of the second frame can be arranged relative to each other, the top surface of the first flexible member and the top surface of the second flexible member can be arranged relative to each other, and at least a portion of the top surface of the protective layer of the first display area and at least a portion of the top surface of the protective layer of the third display area can be in contact. When the electronic device is in a closed state, at least a portion of the protective layer can be in contact, there is no air gap between the first shell and the second shell, and the heat conduction area between the first shell and the second shell is the area where at least a portion of the top surface of the protective layer of the first display area and the top surface of the protective layer of the third display area are in contact, and the heat conduction area of ​​the electronic device is large. Therefore, the heat conduction path between the first shell and the second shell is not easily interrupted by the air gap, the heat conduction speed between the first shell and the second shell is faster, the heat conduction efficiency is higher, and the electronic device in a closed state has a stronger heat dissipation capacity.

[0023] In one possible implementation, the display main layer includes a support layer, a functional layer, and a covering layer arranged in sequence along the second direction. The support layer is located on a side of the functional layer away from the covering layer and is fixedly connected to the first shell and the second shell.

[0024] It is understood that when the electronic device is in a closed state, at least portions of the protective layers can be in contact, and heat generated by components within the first housing can be transferred to the second housing via the support layer of the first display area, the functional layer of the first display area, the cover layer of the first display area, and the protective layer of the first display area. Heat generated by components within the second housing can also be transferred to the first housing via the support layer of the third display area, the functional layer of the third display area, the cover layer of the third display area, and the protective layer of the third display area. The heat conduction path between the first and second housings is not easily interrupted by air gaps, and the heat conduction speed and efficiency between the first and second housings are relatively fast, resulting in a stronger heat distribution capability for the electronic device in a closed state.

[0025] In one possible implementation, the thermal conductivity λ of the support layer satisfies: λ ≥ 300 W·m -1 ·K -1 .

[0026] It can be understood that the higher the thermal conductivity λ of the support layer, the better the thermal conductivity of the support layer.

[0027] In a possible implementation, a first coating layer is provided on the top surface of the protective layer, and a wear rate θ of the first coating layer satisfies: θ≤1%.

[0028] It can be understood that the wear rate θ of the first coating is low, the wear resistance of the first coating is good, and the top surfaces of the first coating and the protective layer are not easily scratched.

[0029] In a possible implementation, a second coating layer is provided on the top surface of the protective layer, and the surface bonding force γ of the second coating layer satisfies: 0.01 N / m≤γ≤0.1 N / m.

[0030] It can be understood that the surface bonding force γ of the second coating layer of the protective layer is relatively small.

[0031] In one possible implementation, the electronic device includes a heating element and a heat dissipation element; the heating element is located on a side of the support layer away from the functional layer, and is fixedly connected to the support layer through a first thermally conductive gel; the heat dissipation element is located on a side of the heating element away from the support layer, and is fixedly connected to the heating element through a second thermally conductive gel.

[0032] It can be understood that the first thermally conductive gel and the second thermally conductive gel can promote heat exchange between the heating element, the heat dissipation element and the display module, and the heat conduction efficiency between the display module and the heating element and the heat dissipation element is high, thereby improving the heat conduction efficiency of the electronic device.

[0033] In one possible implementation, the heat dissipation element is located on the side of the support layer away from the functional layer and is fixedly connected to the support layer through a first thermally conductive gel, and the heating element is located on the side of the heat dissipation element away from the support layer and is fixedly connected to the heating element through a second thermally conductive gel.

[0034] It can be understood that the first thermally conductive gel and the second thermally conductive gel can promote heat exchange between the heating element, the heat dissipation element and the display module, and the heat conduction efficiency between the display module and the heating element and the heat dissipation element is high, thereby improving the heat conduction efficiency of the electronic device.

[0035] In a second aspect, the present application provides an electronic device, which includes a first shell, a second shell, a folding mechanism and a display module. The folding mechanism connects the first shell and the second shell, and the folding mechanism can make the first shell and the second shell relatively unfolded and folded; the display module includes a first display area, a second display area and a third display area arranged in sequence along a first direction, the first display area is fixedly connected to the first shell, and the third display area is fixedly connected to the second shell. The first direction is the direction in which the first shell points to the second shell when the electronic device is in a flattened state; the display module includes a display main layer and a protective layer stacked along a second direction, the display main layer of the first display area is fixedly connected to the first shell, and the display main layer of the third display area is fixedly connected to the second shell. The second direction is different from the first direction; the electronic device also includes a first A decorative piece and a second decorative piece; the first decorative piece is fixedly connected to the first shell, a portion of the first decorative piece is located at the periphery of the display main layer of the first display area, a portion of the first decorative piece protrudes toward the display main layer of the first display area, and covers the edge of the display main layer of the first display area; the second decorative piece is fixedly connected to the second shell, a portion of the second decorative piece is located at the periphery of the display main layer of the third display area, a portion of the second decorative piece protrudes toward the display main layer of the third display area, and covers the edge of the display main layer of the third display area; when the electronic device is in a flattened state, the top surface of the protective layer of the first display area and the top surface of the protective layer of the third display area are both higher than the top surface of the first decorative piece and the top surface of the second decorative piece in the second direction; when the electronic device is in a closed state, the top surface of the protective layer of the first display area and the top surface of the protective layer of the third display area are in contact.

[0036] It can be understood that since the first display area is fixedly connected to the first shell and the third display area is fixedly connected to the second shell, when the first shell and the second shell are relatively expanded or folded, the relative expansion and folding movements between the first display area and the third display area can be accurately controlled, so that the folding process and movement form of the display module are controllable and the reliability is high.

[0037] It is understood that the first decorative member covers the edge of the main display layer in the first display area, and the second decorative member covers the edge of the main display layer in the third display area. Thus, on the one hand, the first decorative member protects the edge of the main display layer in the first display area, and the second decorative member protects the edge of the main display layer in the third display area, thereby improving the reliability of the display module. On the other hand, foreign matter such as dust from the external environment of the electronic device cannot enter the interior of the electronic device, protecting the internal components of the electronic device from interference. Furthermore, the external gaps of the electronic device are covered, making the electronic device more aesthetically pleasing.

[0038] It can be understood that the top surface of the first display area is in contact with the top surface of the third display area, the heat conduction area between the first shell and the second shell is larger, and the heat conduction path is more continuous. Therefore, the heat conduction speed between the first shell and the second shell is faster, the heat conduction efficiency is higher, and the heat distribution capacity of the electronic device is stronger.

[0039] Therefore, this implementation provides an electronic device that can improve both heat distribution capability and reliability.

[0040] In a possible implementation, the thickness h of the protective layer satisfies: 0.1 mm ≤ h ≤ 0.3 mm.

[0041] It is understandable that the thinner the protective layer is, the more advantageous it is to achieve a thinner display module.

[0042] In a possible implementation, the material of the protective layer is polyethylene, polytetrafluoroethylene or nylon.

[0043] It can be understood that the protective layer itself has good wear resistance and is not easily scratched.

[0044] In one possible implementation, the protective layer includes a main layer and a first coating layer stacked along a second direction, the thickness of the main layer is greater than the thickness of the first coating layer, and the wear rate θ of the first coating layer satisfies: θ≤1%; when the electronic device is in a flat state, the top surface of the first coating layer in the first display area, the top surface of the first coating layer in the second display area, and the top surface of the first coating layer in the third display area are all higher than the top surface of the first decorative part and the top surface of the second decorative part in the second direction; when the electronic device is in a closed state, the top surface of the first coating layer in the first display area and the top surface of the first coating layer in the third display area are in contact.

[0045] It is understood that when the electronic device is in a closed state, the first and second housings can be brought closer together, and at least a portion of the top surface of the first coating layer in the first display area can contact at least a portion of the top surface of the first coating layer in the third display area. In this way, the heat conduction path between the first and second housings is less likely to be interrupted by air gaps, the heat conduction speed between the first and second housings is faster, the heat conduction efficiency is higher, and the heat distribution capacity of the electronic device in the closed state is stronger.

[0046] It can be understood that when the electronic device is in a closed state, the contact surfaces of the first display area and the third display area are the top surface of the first coating of the first display area and the top surface of the first coating of the third display area. Since the first coating has good wear resistance, the wear resistance between the top surface of the protective layer of the first display area and the top surface of the protective layer of the third display area is good. During the multiple folding and unfolding of the electronic device, the contact part of the top surface of the first display area and the top surface of the third display area is not easy to wear, and the display effect of the display module is better.

[0047] In one possible implementation, the protective layer includes a main layer and a second coating layer stacked along a second direction, the thickness of the main layer is greater than the thickness of the second coating layer, and the surface bonding force γ of the second coating layer satisfies: 0.01N / m≤γ≤0.01N / m; when the electronic device is in a flat state, the top surface of the second coating layer in the first display area, the top surface of the second coating layer in the second display area, and the top surface of the second coating layer in the third display area are all higher than the top surface of the first decorative member and the top surface of the second decorative member in the second direction; when the electronic device is in a closed state, the top surface of the second coating layer in the first display area and the top surface of the second coating layer in the third display area are in contact.

[0048] It is understood that when the electronic device is in a closed state, the first and second housings can be brought closer together, and at least a portion of the top surface of the second coating layer in the first display area can contact at least a portion of the top surface of the second coating layer in the third display area. In this way, the heat conduction path between the first and second housings is less likely to be interrupted by air gaps, the heat conduction speed between the first and second housings is faster, the heat conduction efficiency is higher, and the heat distribution capacity of the electronic device in the closed state is stronger.

[0049] It can be understood that when the electronic device is in a closed state, the contact surfaces of the first display area and the third display area are the top surface of the second coating of the first display area and the top surface of the second coating of the third display area. Since the surface bonding force of the second coating is relatively low, the surface bonding force between the top surface of the protective layer of the first display area and the top surface of the protective layer of the third display area is relatively weak. During the multiple folding and unfolding of the electronic device, the contact parts of the top surface of the first display area and the top surface of the third display area are easy to separate, and the user experience is better.

[0050] In one possible implementation, the display main layer includes a supporting layer, a functional layer and a covering layer stacked along the second direction; the supporting layer of the first display area is fixedly connected to the first shell, and the supporting layer of the third display area is fixedly connected to the second shell; the covering layer of the first display area includes a first extension portion, the first extension portion extends through the side of the functional layer of the first display area, and a portion of the first decorative member covers the edge of the first extension portion; the covering layer of the third display area includes a second extension portion, the second extension portion extends through the side of the functional layer of the third display area, and a portion of the second decorative member covers the edge of the second extension portion.

[0051] It is understood that the cover layer in the first display area does not shift, thereby preventing breakage or disconnection. The cover layer in the third display area does not shift, thereby preventing breakage or disconnection. In addition, the gaps in the appearance of the electronic device are covered, making the electronic device more aesthetically pleasing.

[0057] It is understood that the covering layer of the first display area can be prevented from shifting, thereby avoiding problems such as breakage or disconnection. At the same time, the covering layer of the first display area is not easily collided with the first fixing portion, and the covering layer of the first display area is not easily damaged, and the covering layer of the first display area has high reliability. In addition, the first covering portion of the first decorative member covers the edge of the first extension portion, preventing dust and other foreign matter from the external environment of the electronic device from entering the interior of the electronic device, protecting the internal components of the electronic device from interference, and covering the external gaps of the electronic device, making the electronic device more aesthetically pleasing.

Furthermore, the external gaps of the electronic device are covered, making the appearance of the electronic device more aesthetically pleasing.

[0060] In one possible implementation, the thermal conductivity λ of the support layer satisfies: λ ≥ 300 W·m -1 ·K -1 .

[0061] It can be understood that the higher the thermal conductivity λ of the support layer, the better the thermal conductivity of the support layer.

[0092] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application.

[0093] In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "install", "connect", "connect", and "connect" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be an electrical connection or a mechanical connection. Among them, "fixed connection" means that the two components are connected to each other and the relative position relationship after connection remains unchanged. "Moveable connection" means that the two components are connected to each other and can move relative to each other after connection. In addition, two components are obtained by an integrated structure through an integrated molding process, which means that in the process of forming one of the two components, the component is connected to the other component, and there is no need to connect the two components together through further processing (such as bonding, welding, snap connection, screw connection). Component A and component B are relatively arranged so that component A is projected along the target direction to obtain projection C, and component B is projected along the target direction to obtain projection D, and projection C and projection D can overlap at least in part.

[0096] Figure 1 It is a structural schematic diagram of the electronic device 100 provided in an embodiment of the present application in a flattened state. Figure 2 yes Figure 1 The electronic device 100 is shown as a partial cross-sectional view of an embodiment of the electronic device 100 at line AA. Figure 1 . Figure 3 yes Figure 1 The electronic device 100 is a schematic structural diagram of an embodiment in a closed state. Figure 4 yes Figure 3 The electronic device 100 is a partial cross-sectional schematic diagram of an embodiment of the electronic device 100 at line BB.

[0097] like Figures 1 to 4 As shown, the present application provides a foldable electronic device 100. The foldable electronic device 100 can be a foldable device such as a mobile phone, a tablet computer, a personal computer, a laptop computer, a vehicle-mounted device, or a wearable device (such as a smart bracelet). The present application embodiment is described in detail using the electronic device 100 as a mobile phone as an example.

[0098] For ease of description, by way of example, the thickness direction of the electronic device 100 is defined as the Z-axis direction, and the extension direction of the rotation axis of the electronic device 100 is defined as the Y-axis direction, that is, the width direction of the electronic device 100 is defined as the Y-axis direction. The direction perpendicular to the Y-axis and the Z-axis is defined as the X-axis direction, that is, the length direction of the electronic device 100 is defined as the X-axis. It is understood that the coordinate system of the electronic device 100 can also be flexibly set according to specific needs.

[0099] It can be understood that in this embodiment, the direction of the rotation axis of the electronic device 100 is the Y-axis direction, that is, the electronic device 100 can be relatively flattened or folded along the Y-axis direction. In this way, when the electronic device 100 is in a closed state, the size of the electronic device 100 in the X-axis direction becomes smaller. This embodiment is explained by taking "the direction of the rotation axis of the electronic device 100 is the Y-axis direction" as an example. At this time, the electronic device 100 can be folded left and right, and the closing and flattening of the electronic device 100 affects the length dimension of the electronic device 100. In some other embodiments, the rotation axis of the electronic device 100 can also be the X-axis direction, that is, the electronic device 100 can be relatively flattened or folded along the X-axis direction. At this time, the electronic device 100 can be folded up and down, and the closing and flattening of the electronic device 100 affects the width dimension of the electronic device 100.

[0100] For example, the first direction is defined as the X-axis direction, the second direction is defined as the Z-axis direction, and the third direction is defined as the Y-axis direction. The first direction, the second direction, and the third direction are different from each other. In other embodiments, the first direction, the second direction, and the third direction can be flexibly set according to needs. This embodiment is not specifically limited.

[0101] Figure 5 yes Figure 1The electronic device 100 is shown in a partially exploded view in one embodiment. Figure 6 yes Figure 5 The electronic device 100 is shown in a partially exploded view in one embodiment.

[0102] like Figure 5 and Figure 6 As shown, the electronic device 100 includes a first shell 1, a second shell 2, a folding mechanism 3 and a display module 4. In other embodiments, the electronic device 100 may include more or fewer structures. For example, when the electronic device 100 may include more structures, the electronic device 100 may also include a camera module (not shown in the drawings). When the electronic device 100 may include fewer structures, the electronic device 100 may also not include the display module 4. It is understandable that Figure 5 The following figures and the related drawings only schematically illustrate some components of the electronic device 100, and the actual shapes, sizes, positions and structures of these components are not affected by the present invention. Figure 5 and the accompanying drawings below.

[0103] Exemplarily, the display screen of the display module 4 can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MID) display screen, a micro organic light-emitting diode (MID) display screen, or a quantum dot light emitting diode (QLED) display screen, etc. In addition, the folding mechanism 3 can be an internal folding mechanism or an external folding mechanism. The internal folding mechanism can be a folding mechanism 3 that folds at least part of the display module 4 between the first shell 1 and the second shell 2. The external folding mechanism can be a folding mechanism 3 that folds at least part of the display module 4 to the outside of the first shell 1 and the second shell 2. The present application does not limit the specific structure of the folding mechanism 3. In this embodiment, the folding mechanism 3 is described as an internal folding mechanism.

[0104] For example, the first direction X may be a direction in which the first housing 1 points toward the second housing 2 when the electronic device 100 is in a flat state.

[0105] like Figure 5 and Figure 6As shown, for example, the folding mechanism 3 is connected between the first housing 1 and the second housing 2. The folding mechanism 3 can enable the first housing 1 and the second housing 2 to be relatively unfolded or folded.

[0106] like Figure 1 and Figure 2 As shown, when the first housing 1 and the second housing 2 are relatively unfolded to a flat state, the electronic device 100 is in a flat state, and the first housing 1 and the second housing 2 can be 180 degrees apart. In other embodiments, the first housing 1 and the second housing 2 can also have a slight deviation from 180 degrees, such as 165 degrees, 177 degrees, or 185 degrees.

[0107] like Figure 3 and Figure 4 As shown, when the first shell 1 and the second shell 2 are folded relative to each other to a closed state, the electronic device 100 is in a closed state, the first shell 1 and the second shell 2 can be closed to each other, and there may be no large gap between the first shell 1 and the second shell 2. In this way, the appearance experience of the electronic device 100 is better, and the waterproof and foreign body-proof performance is better. The situation where the first shell 1 and the second shell 2 are closed includes the situation where the two are against each other, and may also include the situation where there is a small gap between the two. When there is a small gap between the first shell 1 and the second shell 2, some foreign objects outside the electronic device 100 are not easy to enter between the first shell 1 and the second shell 2 through the gap.

[0108] The first shell 1 and the second shell 2 can also be relatively unfolded or folded to an intermediate state, so that the electronic device 100 is in an intermediate state. The intermediate state can be any state between the flattened state and the closed state.

[0109] See also Figure 5 , and combined with Figures 1 to 4 As shown, the display module 4 includes a first display area 41, a second display area 42 and a third display area 43 arranged in sequence along a first direction (ie, the X-axis direction). The second display area 42 is connected between the first display area 41 and the third display area 43. Figure 1 、 Figure 2 and Figure 5 Dashed lines schematically delineate the first display area 41, second display area 42, and third display area 43. The first display area 41 of the display module 4 is fixedly connected to the first housing 1. The third display area 43 is fixedly connected to the second housing 2. During relative expansion or folding of the first and second housings 1, 2, the first housing 1 can move the first display area 41, and the second housing 2 can move the third display area 43. The first and third display areas 41, 43 can expand or fold relative to each other, and the second display area 42 can deform.

[0110] It can be understood that since the first display area 41 is fixedly connected to the first shell 1 and the third display area 43 is fixedly connected to the second shell 2, when the first shell 1 and the second shell 2 are relatively unfolded or folded, the relative unfolding and folding movements between the first display area 41 and the third display area 43 can be accurately controlled, so that the folding process and movement form of the display module 4 are controllable and the reliability is high.

[0111] like Figure 1 and Figure 2 As shown, the first display area 41 may include a top surface 41a, which may be the surface of the first display area 41 away from the first housing 1. The second display area 42 may include a top surface 42a, which may be the surface of the second display area 42 away from the folding mechanism 3. The third display area 43 may include a top surface 43a, which may be the surface of the third display area 43 away from the second housing 2.

[0112] like Figure 1 and Figure 2 As shown, when the electronic device 100 is in a flat state, the first display area 41, the second display area 42, and the third display area 43 of the display module 4 can be in a flat state, that is, the display module 4 can be in a flat state. For example, the top surface 41a of the first display area 41, the top surface 42a of the second display area 42, and the top surface 43a of the third display area 43 of the display module 4 can be 180°. In other embodiments, the top surface 41a of the first display area 41, the top surface 42a of the second display area 42, and the top surface 43a of the third display area 43 can also have a slight deviation from 180°, such as 165°, 177°, or 185°. At this time, the display module 4 has a continuous large display area, that is, the display module 4 can achieve large-screen display, and the user experience is better.

[0113] like Figure 1 and Figure 2 As shown, exemplarily, when the electronic device 100 is in a flattened state, the top surface 41a of the first display area 41 and the top surface 43a of the third display area 43 are both higher than the top surface 1a of the first shell 1 and the top surface 2a of the second shell 2 in the second direction (that is, the positive direction of the Z axis).

[0114] For example, when the electronic device 100 is in the flattened state, the top surface 42a of the second display area 42 can be higher than the top surface 1a of the first housing 1 and the top surface 2a of the second housing 2 in the second direction (i.e., the positive direction of the Z axis). In some embodiments, when the electronic device 100 is in the flattened state, the top surface 42a of the second display area 42 can be lower than the top surface 1a of the first housing 1 and the top surface 2a of the second housing 2 in the second direction. In other embodiments, when the electronic device 100 is in the flattened state, the top surface 42a of the second display area 42 can be flush with the top surface 1a of the first housing 1 and the top surface 2a of the second housing 2 in the second direction.

[0115] like Figure 1 and Figure 2 As shown, for example, when the electronic device 100 is in a flattened state, at least a portion of the folding mechanism 3 can be used to support the second display area 42. In this way, when the second display area 42 is subjected to pressing force, squeezing force, or impact force, the folding mechanism 3 can be used to improve the pressure resistance and impact resistance of the second display area 42, that is, to ensure that the second display area 42 is not prone to problems such as dents.

[0116] like Figure 3 and Figure 4 As shown, when the electronic device 100 is in the closed state, the display module 4 is in the closed state. For example, the top surface 41a of the first display area 41 of the display module 4 is in contact with the top surface 43a of the third display area 43. The second display area 42 is bent. In addition, the display module 4 is located in the space surrounded by the first shell 1, the folding mechanism 3, and the second shell 2. The first display area 41 and the third display area 43 are located between the first shell 1 and the second shell 2. At this time, the planar size of the electronic device 100 is small (having a small width dimension), making it easier for users to carry and store.

[0117] It can be understood that the top surface 41a of the first display area 41 and the top surface 43a of the third display area 43 are in contact, the heat conduction area between the first shell 1 and the second shell 2 is larger, and the heat conduction path is more continuous. Therefore, the heat conduction speed between the first shell 1 and the second shell 2 is faster and the heat conduction efficiency is higher, and the electronic device 100 has a stronger heat distribution ability.

[0118] Figure 7 yes Figure 6 The electronic device 100 is shown as a partially exploded schematic diagram in one embodiment.

[0119] like Figures 5 to 7 As shown, exemplarily, the first shell 1 includes a first frame 11 , a first middle plate 12 and a first flexible member 13 .

[0120] Exemplarily, the first frame 11 may be fixedly connected to the periphery of the first middle plate 12, and the top surface 11a of the first frame 11 may be higher than the top surface 12a of the first middle plate 12. At this time, the top surface 1a of the first housing 1 is the top surface 11a of the first frame 11. The first frame 11 and the first middle plate 12 may be an integrally formed integrated structural member.

[0121] As Figure 7 shown, exemplarily, the first frame 11 includes a first sub-edge 111, a second sub-edge 112, and a third sub-edge 113. The second sub-edge 112 may connect the first sub-edge 111 and the third sub-edge 113, and the first sub-edge 111 and the third sub-edge 113 are disposed opposite to each other. The first frame 11 may be in a "C" shape.

[0122] Exemplarily, one end of the first middle plate 12 close to the second housing 2 forms a first groove 14. The first groove 14 may be recessed relative to the first middle plate 12, and the opening of the first groove 14 may face the second housing 2.

[0123] Figure 8 is Figure 7 an enlarged structural schematic diagram of an implementation manner of the electronic device 100 at C as shown.

[0124] Please refer to Figure 8 , and in combination with Figure 7 shown, exemplarily, the first middle plate 12 is provided with a first mounting groove 15. The first mounting groove 15 may be located at the periphery of the first middle plate 12 and is disposed close to the first frame 11.

[0125] As Figures 5 to 7 shown, exemplarily, the second housing 2 includes a second frame 21, a second middle plate 22, and a second flexible member 23.

[0126] Exemplarily, the second frame 21 may be fixedly connected to the periphery of the second middle plate 22, and the top surface 21a of the second frame 21 may be higher than the top surface 22a of the second middle plate 22. At this time, the top surface 2a of the second housing 2 may be the top surface 21a of the second frame 21. The second frame 21 and the second middle plate 22 may be an integrally formed integrated structural member.

[0127] Exemplarily, the second frame 21 includes a fourth sub-edge 211, a fifth sub-edge 212, and a sixth sub-edge 213. The fifth sub-edge 212 may connect the fourth sub-edge 211 and the sixth sub-edge 213, and the fourth sub-edge 211 and the sixth sub-edge 213 are disposed opposite to each other. The second frame 21 may be in a "C" shape.

[0128] Exemplarily, one end of the second middle plate 22 close to the first housing 1 forms a second groove 24. The second groove 24 may be recessed relative to the second middle plate 22, and the opening of the second groove 24 may face the first housing 1.

[0129] As Figure 5 shown, for example, when the electronic device 100 is in a flattened state, a part of the folding mechanism 3 can be located in the first groove 14, and a part can be located in the second groove 24. At this time, one end of the first middle plate 12 close to the second housing 2 is disposed opposite to the folding mechanism 3, and one end of the second middle plate 22 close to the first housing 1 is disposed opposite to the folding mechanism 3.

[0130] As Figure 7 shown, for example, the second middle plate 22 is provided with a second mounting groove 25. The second mounting groove 25 can be located at the periphery of the second middle plate 22 and is close to the second frame 21.

[0131] As Figure 2 shown, for example, the first display area 41 can be fixedly connected to the first middle plate 12 of the first housing 1. The third display area 43 can be fixedly connected to the second middle plate 22 of the second housing 2.

[0132] Exemplarily, the second direction can be the direction from the first middle plate 12 to the first display area 41 when the electronic device 100 is in a flattened state, that is, the positive direction of the Z axis.

[0133] Exemplarily, the material of the first flexible member 13 can be polyurethane glue, vinyl acrylate glue, silicone rubber glue, or rubber, etc. In other embodiments, the first flexible member 13 can adopt other materials, and specifically, the present application does not make any limitations.

[0134] As Figure 7 shown, for example, the first flexible member 13 can include a first part 131, a second part 132, and a third part 133. The second part 132 can connect the first part 131 and the third part 133, and the first part 131 and the third part 133 can be disposed opposite to each other. The first flexible member 13 can be in a "C" shape.

[0135] It can be understood that the second flexible member 23 and the first flexible member 13 can have the same or similar structures, symmetric structures, or partially symmetric structures, or different structures. In this embodiment, the second flexible member 23 and the first flexible member 13 are symmetric structures. For the basic design of the component structure of the second flexible member 23, the design of the connection relationship between components, and the design of the connection relationship between components and other structures outside the components, the relevant solutions of the first flexible member 13 can be referred to. At the same time, it is allowed that there are some differences in the detailed structure or position arrangement of the components between the second flexible member 23 and the first flexible member 13. Specifically, it will not be elaborated here.

[0136] It is understandable that the first flexible member 13 and the second flexible member 23 can both be made of a material with lower hardness and lower rigidity (such as rubber, etc.), so that when subjected to external force, they can absorb the impact force through deformation to achieve buffering.

[0137] Figure 9 yes Figure 5 The electronic device 100 is a partial cross-sectional schematic diagram of an embodiment of the electronic device 100 at line DD.

[0138] like Figure 9 As shown, illustratively, the first flexible member 13 can be fixedly connected to the first frame 11 .

[0139] See also Figure 9 , and combined with Figure 7 As shown, exemplarily, the first portion 131 of the first flexible member 13 can be fixedly connected to the first sub-edge 111 of the first frame 11 , the second portion 132 can be fixedly connected to the second sub-edge 112 , and the third portion 133 can be fixedly connected to the third sub-edge 113 .

[0140] Exemplarily, at least a portion of the first flexible member 13 may be located in the first mounting groove 15 .

[0141] In other embodiments, the first flexible member 13 may also be fixedly connected to the first middle plate 12, or may be fixedly connected to both the first frame 11 and the first middle plate 12. This application does not limit this in detail.

[0142] like Figure 9 As shown, illustratively, the second flexible member 23 can be fixedly connected to the second frame 21 .

[0143] See also Figure 9 , and combined with Figure 7 As shown, exemplarily, the fourth portion 231 of the second flexible member 23 can be fixedly connected to the fourth sub-edge 211 of the second frame 21 , the fifth portion 232 can be fixedly connected to the fifth sub-edge 212 , and the sixth portion 233 can be fixedly connected to the sixth sub-edge 213 .

[0144] Exemplarily, at least a portion of the second flexible member 23 may be located in the second mounting groove 25 .

[0145] In other embodiments, the second flexible member 23 may also be fixedly connected to the second middle plate 22, or may be fixedly connected to both the second frame 21 and the second middle plate 22. This application does not limit this in detail.

[0146] Figure 10 yes Figure 1 The electronic device 100 is shown as a partial cross-sectional view of an embodiment of the electronic device 100 at line EE. Figure 1 .

[0147] See also Figure 10 , and combined with Figure 7 As shown, the first display area 41 can be spaced apart from the first frame 11, and the first flexible member 13 can be located between the first display area 41 and the first frame 11. For example, the edge of the first display area 41 can be spaced apart from the first frame 11, and the first flexible member 13 can be located between the edge of the first display area 41 and the first frame 11.

[0148] Exemplarily, the first portion 131 of the first flexible member 13 may be located between the first sub-edge 111 of the first frame 11 and the first display area 41, the second portion 132 may be located between the second sub-edge 112 and the first display area 41, and the third portion 133 may be located between the third sub-edge 113 and the first display area 41. Exemplarily, the first portion 131 of the first flexible member 13 may be located between the first sub-edge 111 of the first frame 11 and the edge of the first display area 41, the second portion 132 may be located between the second sub-edge 112 and the edge of the first display area 41, and the third portion 133 may be located between the third sub-edge 113 and the edge of the first display area 41. It can be understood that the first flexible member 13 reduces the gap between the edge of the first display area 41 and the first frame 11, which helps to improve the aesthetic appearance of the electronic device 100.

[0149] For example, the first display area 41 can be spaced apart from the side of the first flexible member 13 near the first display area 41, forming a first gap 5a. For example, the edge of the first display area 41 can be spaced apart from the side of the first flexible member 13 near the edge of the first display area 41, forming a first gap 5a. It will be appreciated that the first gap 5a provides a certain amount of space between the edge of the first display area 41 and the first flexible member 13 for movement. This prevents the edge of the first display area 41 from colliding with the first flexible member 13 during the unfolding or folding of the display module 4 with the electronic device 100, and thus reduces the risk of damage to the first display area, thereby ensuring the reliability of the display module.

[0150] Therefore, this embodiment provides an electronic device that can improve both heat distribution capability and reliability.

[0151] In other embodiments, the edge of the first display area 41 may also be in contact with the first flexible member 13 .

[0152] For example, the third display area 43 can be spaced apart from the second frame 21, and the second flexible member 23 can be located between the third display area 43 and the second frame 21. For example, the edge of the third display area 43 can be spaced apart from the second frame 21, and the second flexible member 23 can be located between the edge of the third display area 43 and the second frame 21.

[0153] For example, the third display area 43 can be spaced apart from the side of the second flexible member 23 near the third display area 43, forming a second gap 5b. For example, the edge of the third display area 43 can be spaced apart from the side of the second flexible member 23 near the edge of the third display area 43, forming a second gap 5b. It will be appreciated that the second gap 5b allows for movement between the edge of the third display area 43 and the second flexible member 23. This prevents the edge of the third display area 43 from colliding with the second flexible member 23 when the display module 4 is unfolded or folded with the electronic device 100.

[0154] In other embodiments, the edge of the third display area 43 may also be in contact with the second flexible member 23 .

[0155] like Figure 10 As shown, for example, the top surface 13a of the first flexible member 13 can be flush with the top surface 11a of the first frame 11 in the second direction. In this case, the top surface 1a of the first shell 1 is the top surface 11a of the first frame 11 and the top surface 13a of the first flexible member 13. The top surface 23a of the second flexible member 23 can be flush with the top surface 21a of the second frame 21 in the second direction. In this case, the top surface 2a of the second shell 2 is the top surface 21a of the second frame 21 and the top surface 23a of the second flexible member 23.

[0156] like Figure 10 As shown, exemplarily, when the electronic device 100 is in a flattened state, when the first shell 1 and the second shell 2 are relatively unfolded to a flattened state (that is, the electronic device 100 is in a flattened state), the top surface 41a of the first display area 41 and the top surface 43a of the third display area 43 are both higher in the second direction than the top surface 11a of the first frame 11, the top surface 21a of the second frame 21, the top surface 13a of the first flexible member 13, and the top surface 23a of the second flexible member 23.

[0157] For example, when the electronic device 100 is in a flattened state, the top surface 42a of the second display area 42 may be higher in the second direction than the top surface 11a of the first frame 11, the top surface 21a of the second frame 21, the top surface 13a of the first flexible member 13, and the top surface 23a of the second flexible member 23. In some embodiments, when the electronic device 100 is in a flattened state, the top surface 42a of the second display area 42 may be lower in the second direction than the top surface 11a of the first frame 11, the top surface 21a of the second frame 21, the top surface 13a of the first flexible member 13, and the top surface 23a of the second flexible member 23. In other embodiments, when the electronic device 100 is in a flattened state, the top surface 42a of the second display area 42 may be flush with the top surface 11a of the first frame 11, the top surface 21a of the second frame 21, the top surface 13a of the first flexible member 13, and the top surface 23a of the second flexible member 23 in the second direction.

[0158] See also Figure 4 For example, when the electronic device 100 is in a closed state, the first shell 1 and the second shell 2 can be close to each other, the top surface 41a of the first display area 41 and the top surface 43a of the third display area 43 can contact each other, and the heat conduction area between the first shell 1 and the second shell 2 is large and the heat conduction path is more continuous. Therefore, the heat conduction speed between the first shell 1 and the second shell 2 is faster and the heat conduction efficiency is higher, and the heat distribution capacity of the electronic device 100 is stronger.

[0159] In some embodiments, when the electronic device 100 is in a flattened state, the top surface 13a of the first flexible member 13 may be higher than the top surface 11a of the first frame 11 in the Z-axis direction. In this case, the top surface 1a of the first housing 1 is the top surface 13a of the first flexible member 13. In other embodiments, when the first housing 1 does not include the first flexible member 13, the top surface 1a of the first housing 1 may be the top surface of another structure, such as the top surface 11a of the first frame 11.

[0160] In some embodiments, when the electronic device 100 is in a flattened state, the top surface 23a of the second flexible member 23 may be higher than the top surface 21a of the second frame 21 in the Z-axis direction. In this case, the top surface 2a of the second housing 2 is the top surface 23a of the second flexible member 23. In other embodiments, when the second housing 2 does not include the second flexible member 23, the top surface 2a of the second housing 2 may be the top surface of another structure, such as the top surface 21a of the second frame 21.

[0161] Figure 11 yes Figure 5 The display module 4 is shown as a partially exploded schematic diagram in one embodiment.

[0162] like Figure 11As shown, the display module 4 includes a protective layer 44 and a display main layer 48, wherein the display main layer 48 includes a cover layer 45, a functional layer 46, and a support layer 47. In other embodiments, the display module 4 may include more or fewer structures. For example, when the display module 4 includes more structures, the display module 4 may also include a light guide plate (not shown in the drawings). When the display module 4 includes fewer structures, the display module 4 may not include the protective layer 44.

[0163] For example, the protective layer 44 may be made of a wear-resistant polymer material, such as polyethylene, polytetrafluoroethylene, nylon, etc. It is understood that the protective layer 44 itself has good wear resistance and is not easily scratched.

[0164] In other embodiments, the protective layer 44 may also be made of other materials, which is not specifically limited in this application.

[0165] For example, the thickness h of the protective layer 44 satisfies: 0.1 mm (millimeter) ≤ h ≤ 0.3 mm (millimeter). For example, h can be 0.1 mm, 0.12 mm, 0.18 mm, 0.2 mm, 0.23 mm, or 0.3 mm. It is understood that the thin thickness of the protective layer 44 is conducive to achieving a thin configuration of the display module 4.

[0166] In other embodiments, the thickness h of the protective layer 44 may also meet other ranges, which is not specifically limited in this application.

[0167] For example, the thermal conductivity λ of the support layer 47 satisfies: λ≥300 W·m -1 ·K -1 (Watts per meter per Kelvin), for example, λ can be 300W·m -1 ·K -1 、328W·m -1 ·K -1 、355.1W·m -1 ·K -1 、426.2W·m -1 ·K -1 、500.38W·m -1 ·K -1 、547W·m -1 ·K -1 or 600W·m -1 ·K -1 It can be understood that the higher the thermal conductivity λ of the support layer 47 is, the better the thermal conductivity of the support layer 47 is.

[0168] In other embodiments, the thermal conductivity λ of the support layer 47 may also meet other ranges, which are not specifically limited in this application.

[0169] For example, the support layer 47 may be made of a material with a strong heat dissipation capability, such as copper, aluminum, graphite, thermally conductive plastic, etc. It is understandable that the material of the support layer 47 itself has a good heat dissipation capability.

[0170] In other embodiments, the support layer 47 may also be made of other materials, which is not specifically limited in this application.

[0171] Figure 12 yes Figure 1 The electronic device 100 is shown as a partial cross-sectional view of an embodiment of the electronic device 100 at line EE. Figure 2 .

[0172] like Figure 12 As shown, for example, when the electronic device 100 is in a flat state, the display body layer 48 and the protective layer 44 can be stacked in sequence along the second direction, that is, the protective layer 44 can be located on a side of the display body layer 48 away from the first shell 1 and the second shell 2. The supporting layer 47, the functional layer 46, and the covering layer 45 can be stacked in sequence along the second direction and fixedly connected.

[0173] Exemplarily, a portion of the support layer 47 can be fixedly connected to the first middle plate 12 of the first shell 1, a portion can be fixedly connected to the second middle plate 22 of the second shell 2, and a portion can be in contact with the folding mechanism 3, that is, this portion may not be fixedly connected to the folding mechanism 3.

[0174] For example, a portion of the support layer 47 may be fixedly connected to the first middle plate 12 via adhesive (not shown in the drawings), and a portion of the support layer 47 may be fixedly connected to the second middle plate 22 via adhesive. In other embodiments, the support layer 47 may also be fixedly connected to the first middle plate 12 and the second middle plate 22 via other methods.

[0175] For example, the functional layer 46 may be located on a side of the supporting layer 47 away from the folding mechanism 3 and fixedly connected to the supporting layer 47 .

[0176] For example, the cover layer 45 may be located on a side of the functional layer 46 away from the support layer 47, that is, the support layer 47 may be located on a side of the functional layer 46 away from the cover layer 45. The cover layer 45 may be fixedly connected to the functional layer 46. The cover layer 45 may include a top surface 45a, and the top surface 45a of the cover layer 45 may be the side of the cover layer 45 away from the functional layer 46.

[0177] For example, the protection layer 44 may be located on a side of the cover layer 45 away from the functional layer 46 .

[0178] Exemplarily, the top surface 41a of the first display area 41 can be the top surface 44a of the protective layer 44 of the first display area 41, the top surface 42a of the second display area 42 can be the top surface 44a of the protective layer 44 of the second display area 42, and the top surface 43a of the third display area 43 can be the top surface 44a of the protective layer 44 of the third display area 43.

[0179] For example, when the electronic device 100 is in a flattened state, the top surface 44a of the protective layer 44 of the first display area 41 and the top surface 44a of the protective layer 44 of the third display area 43 can both be higher than the top surface 11a of the first frame 11, the top surface 21a of the second frame 21, the top surface 13a of the first flexible part 13, and the top surface 23a of the second flexible part 23.

[0180] For example, when the electronic device 100 is in a flattened state, the top surface 44a of the protective layer 44 of the second display area 42 may be higher in the second direction than the top surface 11a of the first frame 11, the top surface 21a of the second frame 21, the top surface 13a of the first flexible member 13, and the top surface 23a of the second flexible member 23. In some embodiments, when the electronic device 100 is in a flattened state, the top surface 44a of the protective layer 44 of the second display area 42 may be lower in the second direction than the top surface 11a of the first frame 11, the top surface 21a of the second frame 21, the top surface 13a of the first flexible member 13, and the top surface 23a of the second flexible member 23. In other embodiments, when the electronic device 100 is in a flattened state, the top surface 44a of the protective layer 44 of the second display area 42 can be flush with the top surface 11a of the first frame 11, the top surface 21a of the second frame 21, the top surface 13a of the first flexible member 13, and the top surface 23a of the second flexible member 23 in the second direction.

[0181] Exemplarily, when the electronic device 100 is in a flattened state, the top surface 45a of the covering layer 45 of the first display area 41 and the top surface 45a of the covering layer 45 of the third display area 43 can both be higher than the top surface 11a of the first frame 11, the top surface 21a of the second frame 21, the top surface 13a of the first flexible member 13, and the top surface 23a of the second flexible member 23.

[0182] For example, when the electronic device 100 is in a flattened state, the top surface 45a of the cover layer 45 of the second display area 42 may be higher in the second direction than the top surface 11a of the first frame 11, the top surface 21a of the second frame 21, the top surface 13a of the first flexible member 13, and the top surface 23a of the second flexible member 23. In some embodiments, when the electronic device 100 is in a flattened state, the top surface 45a of the cover layer 45 of the second display area 42 may be lower in the second direction than the top surface 11a of the first frame 11, the top surface 21a of the second frame 21, the top surface 13a of the first flexible member 13, and the top surface 23a of the second flexible member 23. In other embodiments, when the electronic device 100 is in a flattened state, the top surface 45a of the covering layer 45 of the second display area 42 can be flush with the top surface 11a of the first frame 11, the top surface 21a of the second frame 21, the top surface 13a of the first flexible member 13, and the top surface 23a of the second flexible member 23 in the second direction.

[0183] In other embodiments, the display module 4 may adopt other structures. When the display module 4 does not include the protective layer 44, the top surface 41a of the first display area 41 may be the top surface 45a of the covering layer 45 of the first display area 41, the top surface 42a of the second display area 42 may be the top surface 45a of the covering layer 45 of the second display area 42, and the top surface 43a of the third display area 43 may be the top surface 45a of the covering layer 45 of the third display area 43.

[0184] Figure 13 yes Figure 4 The electronic device 100 is shown as an enlarged schematic diagram of an embodiment at F.

[0185] like Figure 13 As shown, exemplarily, when the electronic device 100 is in a closed state, the first shell 1 and the second shell 2 can be brought close to each other, the top surface 11a of the first frame 11 and the top surface 21a of the second frame 21 can be arranged relative to each other, the top surface 13a of the first flexible part 13 and the top surface 23a of the second flexible part 23 can be arranged relative to each other, and at least a portion of the top surface 44a of the protective layer 44 of the first display area 41 and at least a portion of the top surface 44a of the protective layer 44 of the third display area 43 can be in contact.

[0186] It is understandable that the Figure 13The dashed line with an arrow in the figure only schematically illustrates the heat transfer path of the electronic device 100. For example, components within the electronic device 100 generate heat during operation, and this heat can be transferred from the support layer 47 toward the protective layer 44. When the electronic device 100 is in a closed state, at least a portion of the protective layer 44 can contact each other, and there is no air gap between the first shell 1 and the second shell 2. The heat conduction area between the first shell 1 and the second shell 2 is the area where at least a portion of the top surface 44a of the protective layer 44 of the first display area 41 contacts the top surface 44a of the protective layer 44 of the third display area 43. Therefore, the heat conduction area of ​​the electronic device 100 is relatively large. Heat generated by components within the first housing 1 can be transferred to the second housing 2 in sequence via the support layer 47 of the first display area 41, the functional layer 46 of the first display area 41, the cover layer 45 of the first display area 41, and the protective layer 44 of the first display area 41. Heat generated by components within the second housing 2 can also be transferred to the first housing 1 in sequence via the support layer 47 of the third display area 43, the functional layer 46 of the third display area 43, the cover layer 45 of the third display area 43, and the protective layer 44 of the third display area 43. Therefore, the heat conduction path between the first housing 1 and the second housing 2 is not easily interrupted by air gaps, the heat conduction speed between the first housing 1 and the second housing 2 is fast, the heat conduction efficiency is high, and the electronic device 100 in the closed state has a strong heat distribution capability.

[0187] Figure 14 yes Figure 5 The display module 4 is shown as a partially exploded schematic diagram in another embodiment.

[0188] like Figure 14 As shown, illustratively, the display module 4 may include a first coating 441. The first coating 441 is provided on the surface of the protective layer 44 away from the cover layer 45 (i.e., the top surface 44a of the protective layer 44). The first coating 441 may be a coating that improves the wear resistance of the top surface 44a of the protective layer 44. The wear rate θ of the first coating 441 satisfies: θ≤1%. For example, θ may be 0.01%, 0.05%, 0.2%, 0.5%, 0.66%, 0.9% or 1%. It is understood that the wear rate θ of the first coating 441 is low, the wear resistance of the first coating 441 is good, and the first coating 441 and the top surface 44a of the protective layer 44 are not easily scratched.

[0189] In other embodiments, the wear rate θ of the first coating layer 441 may also meet other ranges, which are not specifically limited in this application.

[0190] For example, the first coating 441 may be made of a wear-resistant ceramic material, such as alumina ceramic, silicon carbide ceramic, boron nitride ceramic, zirconia ceramic, alumina-zirconia composite ceramic, etc. It is understood that the top surface 44 a of the protective layer 44 has better wear resistance.

[0191] In other embodiments, the first coating 441 may also be made of other wear-resistant materials, which is not specifically limited in this application.

[0192] See also Figure 14 , and combined with Figure 12 As shown, exemplarily, the top surface 41a of the first display area 41 may be the top surface 441a of the first coating 441 of the first display area 41, the top surface 42a of the second display area 42 may be the top surface 441a of the first coating 441 of the second display area 42, and the top surface 43a of the third display area 43 may be the top surface 441a of the first coating 441 of the third display area 43.

[0193] It can be understood that when the electronic device 100 is in a flattened state, the top surface 441a of the first coating 441 of the first display area 41 and the top surface 441a of the first coating 441 of the third display area 43 can both be higher than the top surface 11a of the first frame 11, the top surface 21a of the second frame 21, the top surface 13a of the first flexible part 13 and the top surface 23a of the second flexible part 23.

[0194] For example, when the electronic device 100 is in a flattened state, the top surface 441a of the first coating layer 441 of the second display area 42 may be higher in the second direction than the top surface 11a of the first frame 11, the top surface 21a of the second frame 21, the top surface 13a of the first flexible member 13, and the top surface 23a of the second flexible member 23. In some embodiments, when the electronic device 100 is in a flattened state, the top surface 441a of the first coating layer 441 of the second display area 42 may be lower in the second direction than the top surface 11a of the first frame 11, the top surface 21a of the second frame 21, the top surface 13a of the first flexible member 13, and the top surface 23a of the second flexible member 23. In other embodiments, when the electronic device 100 is in a flattened state, the top surface 441a of the first coating 441 of the second display area 42 can be flush with the top surface 11a of the first frame 11, the top surface 21a of the second frame 21, the top surface 13a of the first flexible member 13, and the top surface 23a of the second flexible member 23 in the second direction.

[0195] It will be appreciated that when the electronic device 100 is in a closed state, the first housing 1 and the second housing 2 can be brought closer together, and at least a portion of the top surface 441a of the first coating 441 of the first display area 41 can contact at least a portion of the top surface 441a of the first coating 441 of the third display area 43. This makes it less likely that the heat conduction path between the first housing 1 and the second housing 2 will be interrupted by air gaps, resulting in faster and more efficient heat conduction between the first and second housings 1 and 2, and a stronger heat dissipation capability for the electronic device 100 in a closed state.

[0196] It can be understood that when the electronic device 100 is in a closed state, the contact surfaces of the first display area 41 and the third display area 43 are the top surface 441a of the first coating 441 of the first display area 41 and the top surface 441a of the first coating 441 of the third display area 43. Since the first coating 441 has good wear resistance, the wear resistance between the top surface 44a of the protective layer 44 of the first display area 41 and the top surface 44a of the protective layer 44 of the third display area 43 is good. During the process of folding and unfolding the electronic device 100 many times, the contact part of the top surface 41a of the first display area 41 and the top surface 43a of the third display area 43 is not easy to wear, and the display effect of the display module 4 is better.

[0197] Figure 15 yes Figure 5 The display module 4 shown is a partially exploded schematic diagram in another embodiment.

[0198] like Figure 15 As shown, illustratively, the display module 4 may include a second coating 442. The second coating 442 is provided on the top surface 44a of the protective layer 44. The second coating 442 may be a coating that reduces the surface bonding force of the film layer. The surface bonding force γ of the second coating 442 satisfies: 0.01N / m (Newtons per meter) ≤ γ ≤ 0.1N / m. For example, γ may be 0.01N / m, 0.02N / m, 0.038N / m, 0.05N / m, 0.066N / m, 0.08N / m or 0.1N / m, etc. It is understandable that the surface bonding force γ of the second coating 442 of the protective layer 44 is relatively small. In other embodiments, the surface bonding force γ of the second coating 442 may meet other ranges.

[0199] For example, the second coating layer 442 may be made of materials such as silicone oil, fluorocarbon polymer, silane compound, and fluorocarbon polymer. It is understood that the second coating layer 442 may reduce the surface bonding strength of the film layer on the top surface 44a of the protective layer 44. In other embodiments, the second coating layer 442 may also be made of other materials.

[0200] Exemplarily, the top surface 41a of the first display area 41 may be the top surface 442a of the second coating 442 of the first display area 41, the top surface 42a of the second display area 42 may be the top surface 442a of the second coating 442 of the second display area 42, and the top surface 43a of the third display area 43 may be the top surface 442a of the second coating 442 of the third display area 43.

[0201] It can be understood that when the electronic device 100 is in a flattened state, the top surface 442a of the second coating 442 of the first display area 41 and the top surface 442a of the second coating 442 of the third display area 43 can both be higher than the top surface 11a of the first frame 11, the top surface 21a of the second frame 21, the top surface 13a of the first flexible part 13 and the top surface 23a of the second flexible part 23.

[0202] For example, when the electronic device 100 is in a flattened state, the top surface 442a of the second coating layer 442 of the second display area 42 may be higher in the second direction than the top surface 11a of the first frame 11, the top surface 21a of the second frame 21, the top surface 13a of the first flexible member 13, and the top surface 23a of the second flexible member 23. In some embodiments, when the electronic device 100 is in a flattened state, the top surface 442a of the second coating layer 442 of the second display area 42 may be lower in the second direction than the top surface 11a of the first frame 11, the top surface 21a of the second frame 21, the top surface 13a of the first flexible member 13, and the top surface 23a of the second flexible member 23. In other embodiments, when the electronic device 100 is in a flattened state, the top surface 442a of the second coating 442 of the second display area 42 can be flush with the top surface 11a of the first frame 11, the top surface 21a of the second frame 21, the top surface 13a of the first flexible member 13, and the top surface 23a of the second flexible member 23 in the second direction.

[0203] It will be appreciated that when the electronic device 100 is in a closed state, the first housing 1 and the second housing 2 can be brought closer together, and at least a portion of the top surface 442a of the second coating layer 442 in the first display area 41 can contact at least a portion of the top surface 442a of the second coating layer 442 in the third display area 43. This makes it less likely that the heat conduction path between the first housing 1 and the second housing 2 will be interrupted by air gaps, resulting in faster heat conduction and higher heat conduction efficiency between the first housing 1 and the second housing 2. The electronic device 100, in a closed state, has a stronger heat dissipation capability.

[0204] It can be understood that when the electronic device 100 switches from a closed state to a flat state, the contact surfaces of the first display area 41 and the third display area 43 are the top surface 442a of the second coating 442 of the first display area 41 and the top surface 442a of the second coating 442 of the third display area 43. The surface bonding force between the contact parts of the first display area 41 and the third display area 43 is weak, and the force required for the user to unfold the electronic device 100 is small, which is conducive to improving the user experience.

[0205] Figure 16 yes Figure 1 The electronic device 100 is shown as a partial cross-sectional view of an embodiment of the electronic device 100 at line AA. Figure 2 .

[0206] like Figure 16 As shown, for example, the first display area 41 can enclose a first accommodation space 6a of the electronic device 100 together with the first housing 1. The third display area 43 can enclose a second accommodation space 6b of the electronic device 100 together with the second housing 2. The first accommodation space 6a and the second accommodation space 6b can be used to arrange other components of the electronic device 100.

[0207] For example, the electronic device 100 may include at least one heating element 7a and at least one heat sink 7b. It is understood that the heating element 7a may be a component of the electronic device 100 that generates heat, such as a chip or circuit board; and the heat sink 7b may be a component of the electronic device 100 that helps conduct heat generated by the heating element 7a, such as a vapor chamber.

[0208] For example, the heating element 7a and the heat sink 7b can both be located in the first accommodating space 6a, or both can be located in the second accommodating space 6b. Alternatively, a portion of the heating element 7a and the heat sink 7b can be located in the first accommodating space 6a, and a portion of the heating element 7a and the heat sink 7b can be located in the second accommodating space 6b. This application does not limit this in detail. The following description will take the case where the heating element 7a and the heat sink 7b can both be located in the first accommodating space 6a as an example.

[0209] For example, the heating element 7a can be located on a side of the support layer 47 close to the first middle plate 12 and fixedly connected to the support layer 47. The heat dissipation element 7b can be located on a side of the heating element 7a away from the first middle plate 12 and fixedly connected to the heating element 7a.

[0210] like Figure 16 As shown, the electronic device may further include a first thermally conductive gel 7c and a second thermally conductive gel 7d. For example, the first thermally conductive gel 7c and the second thermally conductive gel 7d may both be composed of components such as silicone resin, a cross-linking agent, a thermally conductive filler, and a curing agent. It is understood that the first thermally conductive gel 7c and the second thermally conductive gel 7d may both have good viscosity and thermal conductivity.

[0211] In other embodiments, the first thermally conductive gel 7c and the second thermally conductive gel 7d may be composed of other components, and the materials of the first thermally conductive gel 7c and the second thermally conductive gel 7d may be the same or different.

[0212] For example, the heating element 7a may be fixedly connected to the supporting layer 47 via a first thermally conductive gel 7c, and the heat dissipating element 7b may be fixedly connected to the heating element 7a via a second thermally conductive gel 7d.

[0213] It can be understood that the first thermally conductive gel 7c and the second thermally conductive gel 7d can promote heat exchange between the heating element 7a, the heat dissipation element 7b and the display module 4, and the heat conduction efficiency between the display module 4 and the heating element 7a, the heat dissipation element 7b is high, thereby improving the heat conduction efficiency of the electronic device 100.

[0214] In other embodiments, the heating element 7a can also be fixedly connected to the support layer 47 and the heat sink 7b by welding, screws, etc. At this time, the heating element 7a can directly contact the heat sink 7b, and the heat generated by the heating element 7a can be directly conducted to the support layer 47 by the heat sink 7b.

[0215] In other embodiments, the heat sink 7b can be located on a side of the support layer 47 away from the functional layer 46 and fixedly connected to the support layer 47 via the first thermally conductive gel 7c. The heating element 7a can be located on a side of the heat sink 7b away from the support layer 47 and fixedly connected to the heating element 7a via the second thermally conductive gel 7d.

[0216] The above describes in detail the structure of the electronic device 100 in some embodiments in conjunction with the relevant drawings. The following describes the structure of the electronic device 100 in some other embodiments in conjunction with the relevant drawings. It is understood that the relevant designs of the electronic device 100 illustrated above can also be directly applied to the structural design of the electronic device 100 illustrated below, if there is no conflict. Among them, most of the technical content that is the same as the electronic device 100 illustrated above will not be repeated below.

[0217] Figure 17 yes Figure 1 The structure diagram of the electronic device 100 in another embodiment is shown. Figure 18 yes Figure 17 The illustrated diagram is a partial cross-sectional view of an embodiment of the electronic device 100 taken along line GG. Figure 19 yes Figure 17 The electronic device 100 is shown as a partially exploded schematic diagram in one embodiment.

[0218] like Figures 17 to 19As shown, the electronic device 100 may include a first shell 1, a second shell 2, a folding mechanism 3, a display module 4, a first decorative member 8 and a second decorative member 9. In other embodiments, the electronic device 100 may include more or fewer structures. For example, when the electronic device 100 may include more structures, the electronic device 100 may also include a camera module (not shown in the drawings). When the electronic device 100 may include fewer structures, the electronic device 100 may also not include the display module 4. It is understandable that Figure 17 The following figures and the related drawings only schematically illustrate some components of the electronic device 100, and the actual shapes, sizes, positions and structures of these components are not affected by the present invention. Figure 5 It is understood that in this embodiment, the type of the display screen of the display module 4 can refer to the relevant solutions in the above embodiments.

[0219] It is understood that the folding mechanism 3 connects the first shell 1 and the second shell 2, and can enable the first shell 1 and the second shell 2 to be relatively unfolded and folded. The specific connection relationship and positional relationship between the first shell 1, the second shell 2, and the folding mechanism 3 can also be referred to the relevant solutions in the above embodiments.

[0220] It is understandable that the hardness and stiffness of the first decorative member 8 and the hardness and stiffness of the second decorative member 9 in this embodiment may be greater than the hardness and stiffness of the first flexible member 13 and the hardness and stiffness of the second flexible member 23 in the previous embodiment.

[0221] like Figures 17 to 19 As shown, the display module 4 includes a first display area 41, a second display area 42 and a third display area 43 arranged in sequence along a first direction (ie, the X-axis direction). The second display area 42 is connected between the first display area 41 and the third display area 43. Figure 17 and Figure 18 The first display area 41 , the second display area 42 and the third display area 43 are schematically distinguished by dotted lines.

[0222] For example, the first display area 41 may include a top surface 41a, which may be a surface of the first display area 41 away from the first housing 1. The second display area 42 may include a top surface 42a, which may be a surface of the second display area 42 away from the folding mechanism 3. The third display area 43 may include a top surface 43a, which may be a surface of the third display area 43 away from the second housing 2.

[0223] Figure 20 yes Figure 19 The display module 4 is shown as a partially exploded schematic diagram in one embodiment.

[0224] like Figure 20 As shown, the display module 4 includes a display main layer 48 and a protection layer 44 stacked along the second direction.

[0225] See also Figure 20 , and combined with Figure 19 As shown, the first display area 41 includes a portion of the protective layer 44 (also referred to as the protective layer 443 of the first display area 41) and a portion of the display body layer 48 (also referred to as the display body layer 481 of the first display area 41). The second display area 42 includes a portion of the protective layer 44 (also referred to as the protective layer 444 of the second display area 42) and a portion of the display body layer 48 (also referred to as the display body layer 482 of the second display area 42). The third display area 43 includes a portion of the protective layer 44 (also referred to as the protective layer 445 of the third display area 43) and a portion of the display body layer 48 (also referred to as the display body layer 483 of the third display area 43).

[0226] See also Figure 20 , and combined with Figure 19 As shown, for example, the top surface 41a of the first display area 41 can be the top surface 443a of the protective layer 443 of the first display area 41, the top surface 42a of the second display area 42 can be the top surface 444a of the protective layer 444 of the second display area 42, and the top surface 43a of the third display area 43 can be the top surface 445a of the protective layer 445 of the third display area 43.

[0227] See also Figure 20 , and combined with Figure 18 As shown, illustratively, the first display area 41 of the display module 4 is fixedly connected to the first shell 1. The third display area 43 is fixedly connected to the second shell 2. Exemplarily, the display main layer 481 of the first display area 41 can be fixedly connected to the first shell 1, and the display main layer 483 of the third display area 43 can be fixedly connected to the second shell 2. During the relative expansion or folding of the first shell 1 and the second shell 2, the first shell 1 can drive the first display area 41 to move, and the second shell 2 can drive the third display area 43 to move. The first display area 41 and the third display area 43 can be relatively expanded or folded, and the second display area 42 can be deformed.

[0228] It can be understood that since the first display area 41 is fixedly connected to the first shell 1 and the third display area 43 is fixedly connected to the second shell 2, when the first shell 1 and the second shell 2 are relatively unfolded or folded, the relative unfolding and folding movements between the first display area 41 and the third display area 43 can be accurately controlled, so that the folding process and movement form of the display module 4 are controllable and the reliability is high.

[0229] Figure 21yes Figure 19 The diagram shows a cross-sectional view of an embodiment of the first decorative element 8 and the second decorative element 9 at line HH.

[0230] like Figure 21 As shown, illustratively, the first decorative element 8 includes a first fixing portion 81, a first protrusion 82, and a first covering portion 83. It is understood that the first decorative element 8 can be an integrally formed structure.

[0231] Exemplarily, the first fixing portion 81 includes a first inner side surface 811 and a first outer side surface 812 disposed in opposite directions.

[0232] Exemplarily, the first inner side surface 811 may be provided with a first protrusion 82 , that is, the first protrusion 82 may be provided on the first fixing portion 81 and protrude in a direction away from the first inner side surface 811 .

[0233] Exemplarily, the first covering portion 83 can be protruded from the first fixing portion 81, a portion of the first covering portion 83 can extend relative to the first inner side surface 811 in a direction away from the first inner side surface 811, and a portion of the first covering portion 83 can extend relative to the first outer side surface 812 in a direction away from the first outer side surface 812.

[0234] For example, the top surface 8a of the first decorative member 8 may be the top surface 83a of the first covering portion 83. In other embodiments, the first decorative member 8 may have other structures, and the top surface 8a of the first decorative member 8 may also have other structures. This application does not limit this in detail.

[0235] like Figure 21 As shown, illustratively, the second decorative member 9 includes a second fixing portion 91, a second protrusion 92, and a second covering portion 93. It is understood that the second decorative member 9 can be an integrally formed structure.

[0236] Exemplarily, the second fixing portion 91 includes a second inner side surface 911 and a second outer side surface 912 disposed in opposite directions.

[0237] Exemplarily, the second inner side surface 911 may be provided with a second protrusion 92 , that is, the second protrusion 92 may be provided on the second fixing portion 91 and protrude in a direction away from the second inner side surface 911 .

[0238] Exemplarily, the second covering portion 93 can be protruded from the second fixing portion 91, and two parts of the second covering portion 93 can extend relative to the second inner side surface 911 in a direction away from the second inner side surface 911, and two parts of the second covering portion 93 can extend relative to the second outer side surface 912 in a direction away from the second outer side surface 912.

[0239] For example, the top surface 9a of the second decorative member 9 may be the top surface 93a of the second covering portion 93. In other embodiments, the second decorative member 9 may have other structures, and the top surface 9a of the second decorative member 9 may also have other structures. This application does not limit this in detail.

[0240] Figure 22 yes Figure 17 The electronic device 100 is shown as a partial cross-sectional view of an embodiment of the electronic device 100 at line II. Figure 1 .

[0241] like Figure 22 As shown, the first decorative member 8 can be fixedly connected to the first shell 1, a portion of the first decorative member 8 can be located around the display main layer 481 of the first display area 41, and a portion can protrude toward the display main layer 481 of the first display area 41 and cover the edge of the display main layer 481 of the first display area 41.

[0242] Exemplarily, the first inner side surface 811 of the first fixing portion 81 of the first decorative member 8 can face the display main layer 481 of the first display area 41, the first protrusion 82 can be fixedly connected to the edge of the display main layer 481 of the first display area 41, the first covering portion 83 can protrude toward the display main layer 481 of the first display area 41, a portion of the first covering portion 83 can be fixedly connected to the first shell 1, and a portion can cover the edge of the display main layer 481 of the first display area 41.

[0243] For example, the edge of the display main layer 481 of the first display area 41 can be fixedly connected to the first protrusion 82, and the edge of the display main layer 481 of the first display area 41 can be spaced apart from the first inner side surface 811 of the first fixing portion 81. It is understandable that during the unfolding or folding process of the electronic device 100, the display main layer 481 of the first display area 41 can be kept from shifting, thereby avoiding the problem of breakage or disconnection. At the same time, the display main layer 481 of the first display area 41 is not likely to collide with the first fixing portion 81, the display main layer 481 of the first display area 41 is not easily damaged, and the display main layer 481 of the first display area 41 is highly reliable.

[0244] like Figure 22 As shown, the second decorative member 9 can be fixedly connected to the second shell 2, a portion of the second decorative member 9 can be located around the display main layer 483 of the third display area 43, and a portion can protrude toward the display main layer 483 of the third display area 43 and cover the edge of the display main layer 481 of the third display area 43.

[0245] Exemplarily, the second inner side surface 911 of the second fixing portion 91 of the second decorative member 9 can face the display main layer 483 of the third display area 43, the second protrusion 92 can be fixedly connected to the edge of the display main layer 483 of the third display area 43, the second covering portion 93 can protrude toward the display main layer 483 of the third display area 43, a portion of the second covering portion 93 can be fixedly connected to the second shell 2, and a portion can cover the edge of the display main layer 483 of the third display area 43.

[0246] For example, the edge of the display main layer 483 of the third display area 43 can be fixedly connected to the second protrusion 92, and the edge of the display main layer 483 of the third display area 43 can be spaced apart from the second inner side surface 911 of the second fixing portion 91. It is understandable that during the unfolding or folding process of the electronic device 100, the display main layer 483 of the third display area 43 can be prevented from shifting, thereby avoiding the problem of breakage or disconnection. At the same time, the display main layer 483 of the third display area 43 is not likely to collide with the second fixing portion 91, and the display main layer 483 of the third display area 43 is not easily damaged, and the display main layer 483 of the third display area 43 is highly reliable.

[0247] See also Figure 22 , and combined with Figure 20 As shown, exemplarily, when the electronic device 100 is in a flattened state, the top surface 443a of the protective layer 443 of the first display area 41 and the top surface 445a of the protective layer 445 of the third display area 43 are both higher than the top surface 8a of the first decorative piece 8 and the top surface 9a of the second decorative piece 9 in the second direction.

[0248] For example, when the electronic device 100 is in a flat state, the top surface 444a of the protective layer 444 of the second display area 42 may be higher in the second direction than the top surface 8a of the first decorative element 8 and the top surface 9a of the second decorative element 9. In some embodiments, when the electronic device 100 is in a flat state, the top surface 444a of the protective layer 444 of the second display area 42 may be lower in the second direction than the top surface 8a of the first decorative element 8 and the top surface 9a of the second decorative element 9. In other embodiments, when the electronic device 100 is in a flat state, the top surface 444a of the protective layer 444 of the second display area 42 may be flush with the top surface 8a of the first decorative element 8 and the top surface 9a of the second decorative element 9 in the second direction.

[0249] Exemplarily, when the electronic device 100 is in the closed state, the top surface 443 a of the protection layer 443 of the first display area 41 and the top surface 445 a of the protection layer 445 of the third display area 43 are in contact.

[0250] It can be understood that the top surface 41a of the first display area 41 and the top surface 43a of the third display area 43 are in contact, the heat conduction area between the first shell 1 and the second shell 2 is larger, and the heat conduction path is more continuous. Therefore, the heat conduction speed between the first shell 1 and the second shell 2 is faster and the heat conduction efficiency is higher, and the electronic device 100 has a stronger heat distribution ability.

[0251] Figure 23 yes Figure 22 The display module 4 is shown as a partially exploded schematic diagram in one embodiment.

[0252] like Figure 23 As shown, illustratively, the display main layer 48 may include a support layer 47 , a functional layer 46 , and a cover layer 45 stacked along the second direction.

[0253] See also Figure 23 , and combined with Figure 22 As shown, for example, the first display area 41 may include a portion of the covering layer 45 (also referred to as the covering layer 451 of the first display area 41), a portion of the functional layer 46 (also referred to as the functional layer 461 of the first display area 41), and a portion of the supporting layer 47 (also referred to as the supporting layer 471 of the first display area 41). The second display area 42 may include a portion of the covering layer 45 (also referred to as the covering layer 452 of the second display area 42), a portion of the functional layer 46 (also referred to as the functional layer 462 of the second display area 42), and a portion of the supporting layer 47 (also referred to as the supporting layer 472 of the second display area 42). The third display area 43 may include a portion of the covering layer 45 (also referred to as the covering layer 453 of the third display area 43), a portion of the functional layer 46 (also referred to as the functional layer 463 of the third display area 43), and a portion of the supporting layer 47 (also referred to as the supporting layer 473 of the third display area 43).

[0254] like Figure 22 As shown, illustratively, the support layer 471 of the first display area 41 can be fixedly connected to the first shell 1 , and the support layer 473 of the third display area 43 can be fixedly connected to the second shell 2 .

[0255] See also Figure 23 , and combined with Figure 22 As shown, illustratively, the covering layer 451 of the first display area 41 includes a first protruding portion 4511 , and the first protruding portion 4511 may protrude through a side surface of the functional layer 461 of the first display area 41 .

[0256] See also Figure 22, for example, the first protrusion 4511 can be spaced apart from the first inner side surface 811 of the first fixing portion 81, the first protrusion 4511 can be fixedly connected to the first protrusion 82, and a portion of the first decorative member 8 (i.e., the first covering portion 83) can cover the edge of the first protrusion 4511. It can be understood that the covering layer 451 of the first display area 41 can be prevented from shifting, thereby avoiding the problem of breakage or disconnection. At the same time, the covering layer 451 of the first display area 41 is not easy to collide with the first fixing portion 81, the covering layer 451 of the first display area 41 is not easy to be damaged, and the reliability of the covering layer 451 of the first display area 41 is higher. In addition, the first covering portion 83 of the first decorative member 8 covers the edge of the first protrusion 4511. In this way, on the one hand, the first decorative member can protect the edge of the display main layer of the first display area, thereby improving the reliability of the display module. On the other hand, foreign matter such as dust in the external environment of the electronic device 100 cannot enter the interior of the electronic device 100, the internal components of the electronic device 100 can be protected from interference, and the appearance gaps of the electronic device 100 are covered, so the appearance of the electronic device 100 is more beautiful.

[0257] See also Figure 23 , and combined with Figure 22 As shown, illustratively, the covering layer 453 of the third display area 43 includes a second protruding portion 4531 , and the second protruding portion 4531 may protrude through a side surface of the functional layer 463 of the third display area 43 .

[0258] See also Figure 22 , for example, the second protrusion 4531 can be spaced apart from the second inner side surface 911 of the second fixing portion 91, the second protrusion 4531 can be fixedly connected to the second protrusion 92, and a portion of the second decorative member 9 (i.e., the second covering portion 93) can cover the edge of the second protrusion 4531. It can be understood that the covering layer 453 of the third display area 43 can be prevented from shifting, thereby avoiding the problem of breakage or disconnection. At the same time, the covering layer 453 of the third display area 43 is not easy to collide with the second fixing portion 91, the covering layer 453 of the third display area 43 is not easy to be damaged, and the reliability of the covering layer 453 of the third display area 43 is higher. In addition, the second covering portion 93 of the second decorative member 9 covers the edge of the second protrusion 4531. In this way, on the one hand, the second decorative member can protect the edge of the display main layer of the third display area, thereby improving the reliability of the display module. On the other hand, foreign matter such as dust in the external environment of the electronic device 100 cannot enter the interior of the electronic device 100, the internal components of the electronic device 100 can be protected from interference, and the appearance gaps of the electronic device 100 are covered, so the appearance of the electronic device 100 is more beautiful.

[0259] Therefore, this embodiment provides an electronic device that can improve both heat distribution capability and reliability.

[0260] Figure 24 yes Figure 22 The display module 4 is shown as a partially exploded schematic diagram in another embodiment.

[0261] like Figure 24 As shown, illustratively, the protection layer 44 may include a main layer 446 and a first coating layer 441 stacked along the second direction.

[0262] Exemplarily, the thickness of the main layer 446 is greater than the thickness of the first coating layer 441 .

[0263] For example, the first coating layer 441 can be a coating that improves the wear resistance of the top surface 44a of the protective layer 44. The wear rate θ of the first coating layer 441 satisfies: θ≤1%. For example, θ can be 0.01%, 0.05%, 0.2%, 0.5%, 0.66%, 0.8%, 0.9%, or 1%. It can be understood that the lower the wear rate θ of the first coating layer 441, the better the wear resistance of the first coating layer 441, and the first coating layer 441 and the protective layer 44 are not easily scratched.

[0264] For example, the first coating 441 can be made of a wear-resistant ceramic material, such as alumina ceramic, silicon carbide ceramic, boron nitride ceramic, zirconia ceramic, or alumina-zirconia composite ceramic. It is understood that the top surface 44a of the protective layer 44 has excellent wear resistance. In other embodiments, the wear rate θ of the first coating 441 can meet other ranges, and the first coating 441 can also be made of other wear-resistant materials.

[0265] See also Figure 24 , and combined with Figure 22 As shown, for example, the first display area 41 may include a portion of the first coating layer 441 (also referred to as the first coating layer 4411 of the first display area 41) and a portion of the main layer 446 (also referred to as the main layer 4461 of the first display area 41). The second display area 42 may include a portion of the first coating layer 441 (also referred to as the first coating layer 4412 of the second display area 42) and a portion of the main layer 446 (also referred to as the main layer 4462 of the second display area 42). The third display area 43 may include a portion of the first coating layer 441 (also referred to as the first coating layer 4413 of the third display area 43) and a portion of the main layer 446 (also referred to as the main layer 4463 of the third display area 43).

[0266] See also Figure 24 , and combined with Figure 22As shown, for example, the top surface 4411a of the first coating 4411 of the first display area 41 can be the top surface 41a of the first display area 41, the top surface 4412a of the first coating 4412 of the second display area 42 can be the top surface 42a of the second display area 42, and the top surface 4413a of the first coating 4413 of the third display area 43 can be the top surface 43a of the third display area 43.

[0267] It can be understood that when the electronic device 100 is in a flat state, the top surface 4411a of the first coating 4411 of the first display area 41 and the top surface 4413a of the first coating 4413 of the third display area 43 can both be higher than the top surface 8a of the first decorative piece 8 and the top surface 9a of the second decorative piece 9.

[0268] For example, when the electronic device 100 is in a flat state, the top surface 4412a of the first coating layer 4412 of the second display area 42 may be higher in the second direction than the top surface 8a of the first decorative element 8 and the top surface 9a of the second decorative element 9. In some embodiments, when the electronic device 100 is in a flat state, the top surface 4412a of the first coating layer 4412 of the second display area 42 may be lower in the second direction than the top surface 8a of the first decorative element 8 and the top surface 9a of the second decorative element 9. In other embodiments, when the electronic device 100 is in a flat state, the top surface 4412a of the first coating layer 4412 of the second display area 42 may be flush with the top surface 8a of the first decorative element 8 and the top surface 9a of the second decorative element 9 in the second direction.

[0269] It will be appreciated that when the electronic device 100 is in a closed state, the first housing 1 and the second housing 2 can be brought closer together, and at least a portion of the top surface 4411a of the first coating 4411 of the first display area 41 can contact at least a portion of the top surface 4413a of the first coating 4413 of the third display area 43. This makes it possible for the heat conduction path between the first housing 1 and the second housing 2 to be less likely to be interrupted by air gaps, resulting in faster and more efficient heat conduction between the first and second housings 1 and 2. This allows the electronic device 100 to achieve a stronger heat distribution capability when in a closed state.

[0270] It can be understood that when the electronic device 100 is in a closed state, the contact surfaces of the first display area 41 and the third display area 43 are the top surface 4411a of the first coating 4411 of the first display area 41 and the top surface 4413a of the first coating 4413 of the third display area 43. Since the first coating 441 has good wear resistance, the wear resistance between the top surface 443a of the protective layer 443 of the first display area 41 and the top surface 445a of the protective layer 445 of the third display area 43 is good. During the process of folding and unfolding the electronic device 100 many times, the contact part of the top surface 41a of the first display area 41 and the top surface 43a of the third display area 43 is not easy to wear, and the display effect of the display module 4 is better.

[0271] Figure 25 yes Figure 22 The display module 4 shown is a partially exploded schematic diagram in another embodiment.

[0272] like Figure 25 As shown, exemplarily, the protective layer 44 includes a main layer 446 and a second coating layer 442 stacked along the second direction.

[0273] Illustratively, the thickness of the main layer 446 is greater than the thickness of the second coating layer 442 .

[0274] For example, the second coating layer 442 may be a coating that reduces the surface bonding force of the film layer. The surface bonding force γ of the second coating layer 442 satisfies the following conditions: 0.01 N / m (Newtons per meter) ≤ γ ≤ 0.1 N / m (Newtons per meter). For example, γ may be 0.01 N / m, 0.02 N / m, 0.038 N / m, 0.05 N / m, 0.066 N / m, 0.08 N / m, or 0.1 N / m. It is understood that the surface bonding force γ of the second coating layer 442 of the protective layer 44 is relatively small. In other embodiments, the surface bonding force γ of the second coating layer 442 may meet other ranges.

[0275] For example, the second coating layer 442 may be made of silicone oil, fluorocarbon polymer, silane compound, fluorocarbon polymer, etc. In other embodiments, the second coating layer 442 may also be made of other materials that reduce the surface bonding force of the film layer.

[0276] See also Figure 25 , and combined with Figure 22As shown, for example, the first display area 41 may include a portion of the second coating layer 442 (also referred to as the second coating layer 4421 of the first display area 41) and a portion of the main layer 446 (also referred to as the main layer 4461 of the first display area 41). The second display area 42 may include a portion of the second coating layer 442 (also referred to as the second coating layer 4422 of the second display area 42) and a portion of the main layer 446 (also referred to as the main layer 4462 of the second display area 42). The third display area 43 may include a portion of the second coating layer 442 (also referred to as the second coating layer 4423 of the third display area 43) and a portion of the main layer 446 (also referred to as the main layer 4463 of the third display area 43).

[0277] See also Figure 25 , and combined with Figure 22 As shown, for example, the top surface 4421a of the second coating 4421 of the first display area 41 can be the top surface 41a of the first display area 41, the top surface 4422a of the second coating 4422 of the second display area 42 can be the top surface 42a of the second display area 42, and the top surface 4423a of the second coating 4423 of the third display area 43 can be the top surface 43a of the third display area 43.

[0278] It can be understood that when the electronic device 100 is in a flat state, the top surface 4421a of the second coating 4421 of the first display area 41 and the top surface 4423a of the second coating 4423 of the third display area 43 can both be higher than the top surface 8a of the first decorative piece 8 and the top surface 9a of the second decorative piece 9.

[0279] For example, when the electronic device 100 is in a flat state, the top surface 4422a of the second coating layer 4422 of the second display area 42 may be higher in the second direction than the top surface 8a of the first decorative element 8 and the top surface 9a of the second decorative element 9. In some embodiments, when the electronic device 100 is in a flat state, the top surface 4422a of the second coating layer 4422 of the second display area 42 may be lower in the second direction than the top surface 8a of the first decorative element 8 and the top surface 9a of the second decorative element 9. In other embodiments, when the electronic device 100 is in a flat state, the top surface 4422a of the second coating layer 4422 of the second display area 42 may be flush with the top surface 8a of the first decorative element 8 and the top surface 9a of the second decorative element 9 in the second direction.

[0280] It will be appreciated that when the electronic device 100 is in a closed state, the first housing 1 and the second housing 2 can be brought closer together, and at least a portion of the top surface 4421a of the second coating layer 4421 of the first display area 41 can contact at least a portion of the top surface 4423a of the second coating layer 4423 of the third display area 43. This makes it less likely that the heat conduction path between the first housing 1 and the second housing 2 will be interrupted by air gaps, resulting in faster and more efficient heat conduction between the first and second housings 1 and 2. This allows the electronic device 100 to achieve a stronger heat distribution capability when in a closed state.

[0281] It can be understood that when the electronic device 100 is in a closed state, the contact surfaces of the first display area 41 and the third display area 43 are the top surface 4421a of the second coating 4421 of the first display area 41 and the top surface 4423a of the second coating 4423 of the third display area 43. Since the surface bonding force of the second coating 442 is relatively low, the surface bonding force between the top surface 443a of the protective layer 443 of the first display area 41 and the top surface 445a of the protective layer 445 of the third display area 43 is relatively weak. During the process of folding and unfolding the electronic device 100 multiple times, the contact parts of the top surface 41a of the first display area 41 and the top surface 43a of the third display area 43 are easy to separate, and the user experience is better.

[0282] like Figure 24 and Figure 25 As shown, for example, the material of the protective layer 44 can be a wear-resistant polymer material, such as polyethylene, polytetrafluoroethylene, nylon, etc. It is understandable that the protective layer 44 itself has good wear resistance and is not easily scratched.

[0283] In other embodiments, the protective layer 44 may also be made of other materials, which is not specifically limited in this application.

[0284] For example, the thickness h of the protective layer 44 satisfies: 0.1 mm (millimeter) ≤ h ≤ 0.3 mm (millimeter). For example, h can be 0.1 mm, 0.12 mm, 0.18 mm, 0.2 mm, 0.23 mm, or 0.3 mm. It is understood that the thin thickness of the protective layer 44 is conducive to achieving a thin configuration of the display module 4.

[0285] In other embodiments, the thickness h of the protective layer 44 may also meet other ranges, which is not specifically limited in this application.

[0286] For example, the thermal conductivity λ of the support layer 47 satisfies: λ≥300 W·m -1 ·K -1 (Watts per meter per Kelvin), for example, λ can be 300W·m -1 ·K -1 、328W·m-1 ·K -1 、355.1W·m -1 ·K -1 、426.2W·m -1 ·K -1 、500.38W·m -1 ·K -1 、547W·m -1 ·K -1 or 600W·m -1 ·K -1 It can be understood that the higher the thermal conductivity λ of the support layer 47 is, the better the thermal conductivity of the support layer 47 is.

[0287] In other embodiments, the thermal conductivity λ of the support layer 47 may meet other ranges, which are not specifically limited in this application.

[0288] For example, the support layer 47 may be made of a material with a strong heat dissipation capability, such as copper, aluminum, graphite, thermally conductive plastic, etc. It is understandable that the material of the support layer 47 itself has a good heat dissipation capability.

[0289] In other embodiments, the support layer 47 may also be made of other materials, which is not specifically limited in this application.

[0290] Figure 26 yes Figure 17 The electronic device 100 is shown as a partial cross-sectional view of an embodiment of the electronic device 100 at line II. Figure 2 .

[0291] like Figure 26 As shown, for example, the heating element 7a and the heat sink 7b can both be located in the first accommodating space 6a, or both in the second accommodating space 6b, or a portion of the heating element 7a and the heat sink 7b can be located in the first accommodating space 6a, and a portion of the heating element 7a and the heat sink 7b can be located in the second accommodating space 6b. This application does not limit this specifically. The following description takes the case where the heating element 7a and the heat sink 7b can both be located in the first accommodating space 6a as an example.

[0292] For example, the heating element 7a can be located on a side of the support layer 47 close to the first housing 1 and fixedly connected to the support layer 47. The heat dissipation element 7b can be located on a side of the heating element 7a away from the first housing 1 and fixedly connected to the heating element 7a.

[0293] like Figure 26As shown, the electronic device may further include a first thermally conductive gel 7c and a second thermally conductive gel 7d. For example, the first thermally conductive gel 7c and the second thermally conductive gel 7d may both be composed of components such as silicone resin, a cross-linking agent, a thermally conductive filler, and a curing agent. It is understood that the first thermally conductive gel 7c and the second thermally conductive gel 7d may both have good viscosity and thermal conductivity.

[0294] In other embodiments, the first thermally conductive gel 7c and the second thermally conductive gel 7d may be composed of other components, and the materials of the first thermally conductive gel 7c and the second thermally conductive gel 7d may be the same or different.

[0295] For example, the heating element 7a may be fixedly connected to the supporting layer 47 via a first thermally conductive gel 7c, and the heat dissipating element 7b may be fixedly connected to the heating element 7a via a second thermally conductive gel 7d.

[0296] It can be understood that the first thermally conductive gel 7c and the second thermally conductive gel 7d can promote heat exchange between the heating element 7a, the heat dissipation element 7b and the display module 4, and the heat conduction efficiency between the display module 4 and the heating element 7a, the heat dissipation element 7b is high, thereby improving the heat conduction efficiency of the electronic device 100.

[0297] In other embodiments, the heating element 7a may be fixedly connected to the support layer 47 and the heat sink 7b by welding, screws, or the like. In this case, the heating element 7a may be in direct contact with the heat sink 7b, and the heat generated by the heating element 7a may be directly transferred from the heat sink 7b to the support layer 47. In other embodiments, the heat sink 7b may be located on a side of the support layer 47 away from the functional layer 46 and fixedly connected to the support layer 47 via a first thermally conductive gel 7c. The heating element 7a may be located on a side of the heat sink 7b away from the support layer 47 and fixedly connected to the heating element 7a via a second thermally conductive gel 7d.

[0298] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments in this application can be combined with each other, and any combination of features in different embodiments is also within the protection scope of this application, that is, the multiple embodiments described above can also be arbitrarily combined according to actual needs. It should be noted that all the above-mentioned drawings are illustrative illustrations of this application and do not represent the actual size of the product. And the dimensional ratio relationship between the components in the drawings does not serve as a limitation on the actual product of this application. The above are only some of the embodiments and implementation methods of this application. The protection scope of this application is not limited to this. Any person skilled in the art who is familiar with the technical scope disclosed in this application can easily think of changes or replacements, which should be covered within the protection scope of this application. Therefore, the protection scope of this application should be based on the protection scope of the claims.
