[0003] With the development of technology and the demand of electronic device market, the application of foldable electronic device is more and more widely. Multi-fold electronic device with more than two folding times can balance portability and large screen experience, which is the research direction of new products of foldable electronic device. The three-fold electronic device generally includes a first housing, a second housing, a third housing, a first folding mechanism and a second folding mechanism.

The second folding mechanism connects the second housing and the third housing, and the second folding mechanism can drive the second housing and the third housing to unfold or fold relatively. However, since the cross sections of the traditional first housing, the second housing and the third housing are all rectangular, when the three-fold electronic device is in a closed state, the thickness of the three-fold electronic device is relatively thick, which is not conducive to the thinness of the electronic device. SUMMARY

[0004] The present application provides an electronic device with a relatively thin thickness.

[0005] In a first aspect, the present application provides an electronic device. The electronic device comprises a first body, a second body, a third body, a first folding mechanism and a second folding mechanism. The first folding mechanism connects the first body and the second body, and is configured to unfold or fold the first body and the second body relative to each other. The second folding mechanism connects the second body and the third body, and is configured to unfold or fold the second body and the third body relative to each other. The first body comprises a first upper surface and a first lower surface arranged oppositely. The second body comprises a second upper surface and a second lower surface arranged oppositely. The third body comprises a third upper surface and a third lower surface arranged oppositely. When the electronic device is in a flat state, the first body, the second body and the third body are arranged along a first direction. The first upper surface, the second upper surface and the third upper surface are in the same plane. The first lower surface is closer to the first upper surface in a direction away from the first folding mechanism. The second lower surface is closer to the second upper surface in a direction away from the first folding mechanism. The third lower surface is closer to the third upper surface in a direction away from the second folding mechanism. When the electronic device is in a first closed state, the first body, the third body and the second body are arranged along a second direction. The first upper surface is arranged opposite to the third lower surface. The second upper surface is arranged opposite to the third upper surface. The first lower surface is closer to the first upper surface in a direction away from the first folding mechanism. The third lower surface is closer to the third upper surface in a direction towards the first folding mechanism. The second lower surface is closer to the second upper surface in a direction towards the second folding mechanism. The second direction is different from the first direction. The second body is provided with a mounting hole, which is open at the second lower surface. The electronic device further comprises a camera decoration piece, which is fixedly connected to the second body and covers the mounting hole. The camera decoration piece comprises a first surface arranged opposite to the second lower surface. When the electronic device is in the first closed state, an angle a between the first surface of the camera decoration piece and the first lower surface satisfies: 0°≤a≤10°.

[0006] It can be understood that, since the end of the first body away from the first folding mechanism is not easily limited by the first folding mechanism, and the end of the third body away from the second folding mechanism is not easily limited by the second folding mechanism, the present application can reduce the thickness of the end of the first body away from the first folding mechanism and the thickness of the end of the third body away from the second folding mechanism, so that the first upper surface of the first body can be closer to the first lower surface in a direction away from the first folding mechanism, and the third lower surface of the third body can be closer to the third upper surface in a direction away from the second folding mechanism. In this way, through the cooperation of the first upper surface of the first body and the third lower surface of the third body, the electronic device can be thinned when in the first closed state.

[0007] It can be understood that, since the end of the second main body away from the first folding mechanism is not easily limited by the first folding mechanism, and the end of the third main body away from the second folding mechanism is not easily limited by the second folding mechanism, the thickness of the end of the second main body away from the first folding mechanism and the thickness of the end of the third main body away from the second folding mechanism can be reduced, so that the second lower surface of the second main body can be close to the second upper surface in the direction away from the first folding mechanism, and the third lower surface of the third main body can be close to the third upper surface in the direction away from the second folding mechanism. In this way, through the cooperation of the first upper surface of the first main body, the second lower surface of the second main body, and the third lower surface of the third main body, the electronic device can be thinned when in the first closed state.

[0008] It can be understood that, through the cooperation of the first upper surface of the first main body and the third lower surface of the third main body, and the cooperation of the first upper surface of the first main body, the second lower surface of the second main body, and the third lower surface of the third main body, the electronic device can be thinned when in the first closed state. In particular, for some foldable electronic devices with a large screen bending angle, such as foldable electronic devices with a water drop screen. When the thinning method of the present application is used, the foldable electronic device can be effectively thinned while having enough space to accommodate the screen, thereby improving the user experience of the foldable electronic device.

[0009] It can be understood that, by setting the angle a between the first face of the camera decoration piece and the first lower surface in the range of 0° to 10°, the first face of the camera decoration piece can be substantially parallel to the first lower surface of the first main body when the electronic device is in the first closed state. When the user places the electronic device in the first closed state on a table or the like, the first face of the camera decoration piece can be in contact with the table or the like, and the first lower surface of the first main body can be substantially parallel to the table or the like. In this way, while achieving thinning of the electronic device, the electronic device in the first closed state can be placed relatively neatly on the table or the like, and the electronic device has high delicacy. In addition, when the user uses the electronic device in the first closed state to take a photo, the first face of the camera decoration piece and the first lower surface of the first main body can both be substantially perpendicular to the user's line of sight, the camera module can be easily photographed, and the user's experience is better.

[0010] In a possible implementation, the thickness of the end of the first main body away from the first folding mechanism is a first thickness A1, and the thickness of the end of the first main body close to the first folding mechanism is a second thickness A2; the first thickness A1 and the second thickness A2 satisfy: A1>A2.

[0011] It can be understood that the thickness of the first body near the first folding mechanism is larger, the width of the first folding mechanism can not need to be reduced, the reliability of the first folding mechanism is higher, and the reliability of the electronic device is higher.

[0012] In a possible implementation, the thickness of the second body near the first folding mechanism is a third thickness B1, and the thickness of the second body away from the first folding mechanism is a fourth thickness B2; the third thickness B1 and the fourth thickness B2 satisfy: B1>B2.

[0013] It can be understood that the thickness of the second body near the first folding mechanism is larger, the width of the first folding mechanism can not need to be reduced, the reliability of the first folding mechanism is higher, and the reliability of the electronic device is higher.

[0014] In a possible implementation, the thickness of the third body away from the second folding mechanism is a fifth thickness C1, and the thickness of the second body near the second folding mechanism is a sixth thickness C2; the fifth thickness C1 and the sixth thickness C2 satisfy: C1

[0015] It can be understood that the thickness of the third body near the second folding mechanism is larger, the width of the second folding mechanism can not need to be reduced, the reliability of the second folding mechanism is higher, and the reliability of the electronic device is higher.

[0016] In a possible implementation, the first thickness A1 and the third thickness B1 satisfy: |B1-A1|≤1.5mm.

[0017] It can be understood that, by setting the absolute value of the difference between the first thickness A1 and the third thickness B1 to be within the range of less than or equal to 1.5mm, the difference between the thickness of the first body near the first folding mechanism and the thickness of the second body near the first folding mechanism is smaller, and the user's experience is better when the electronic device is in the unfolded state.

[0018] In a possible implementation, the fourth thickness B2 and the sixth thickness C2 satisfy: |B2-C2|≤1.5mm.

[0019] It can be understood that, by setting the absolute value of the difference between the fourth thickness B2 and the sixth thickness C2 to be within the range of less than or equal to 1.5mm, the difference between the thickness of the second body near the second folding mechanism and the thickness of the third body near the second folding mechanism is smaller, and the user's experience is better when the electronic device is in the unfolded state.

[0020] In a possible implementation, when the electronic device is in the first closed state, the angle b between the first surface of the camera decoration piece and the second lower surface can satisfy: 0°≤b≤10°.

[0021] It can be understood that by setting the angle b between the first surface of the camera decoration piece and the second lower surface in the range of 0° to 10°, when the electronic device is in the first closed state, the first surface of the camera decoration piece and the second lower surface of the second main body can be substantially parallel.

[0022] In a possible implementation, the electronic device includes a first shell, a second shell, a third shell, and a first display screen; the first display screen includes a first display area, a second display area, a third display area, a fourth display area, and a fifth display area connected in sequence, the first display area is fixedly connected with the first shell, the third display area is fixedly connected with the second shell, the fifth display area is fixedly connected with the third shell, the second display area is arranged opposite to the first folding mechanism and can be bent, and the fourth display area is arranged opposite to the second folding mechanism and can be bent; a surface of the first display area away from the first shell is a first upper surface of a first main body, a surface of the first shell away from the first display area is a first lower surface of the first main body, a surface of the third display area away from the second shell is a second upper surface of a second main body, a surface of the second shell away from the third display area is a second lower surface of the second main body, a surface of the fifth display area away from the third shell is a third upper surface of a third main body, and a surface of the third shell away from the fifth display area is a third lower surface of the third main body.

[0023] It can be understood that since the electronic device is in the first closed state, the first main body, the third main body, and the second main body can be arranged along the second direction, and the first upper surface can be arranged opposite to the third lower surface and the second upper surface can be arranged opposite to the third upper surface, then the first lower surface and the second lower surface can be located on the outside of the electronic device, the first upper surface, the second upper surface, the third upper surface, and the third lower surface can be located on the inside of the electronic device, the first display screen can be located on the inside of the electronic device, and the first main body, the second main body, and the third main body can protect the first display screen and prevent the first display screen from being scratched.

[0024] In a possible implementation, the second shell includes a second middle frame and a second back cover; the second middle frame includes a first surface and a second surface arranged in reverse, and the third display area is fixedly connected with the first surface of the second middle frame; the second back cover is fixedly connected with the second surface of the second middle frame, and a surface of the second back cover away from the second middle frame is the second lower surface of the second main body; the second surface of the second middle frame approaches the first surface of the second middle frame in a direction away from the first folding mechanism, the second middle frame and the second back cover enclose a first accommodation space, and a thickness of the first accommodation space decreases in a direction away from the first folding mechanism.

[0025] It can be understood that by setting the second surface of the second middle frame to be close to the first surface of the second middle frame in a direction away from the first folding mechanism, the thickness of the second shell can be reduced in the direction away from the first folding mechanism, so that the thickness of the second main body can also be reduced in the direction away from the first folding mechanism. In this way, the structure for reducing the thickness of the second main body is relatively simple, and the process is relatively easy.

[0026] In a possible implementation, the second main body includes a first battery, the first battery is located in the first accommodation space, and is fixedly connected with the second middle frame, and the thickness of the first battery is reduced in the direction away from the first folding mechanism.

[0027] It can be understood that the first battery is located in the first accommodation space, and since the thickness of the first accommodation space and the thickness of the first battery can be reduced in the direction away from the first folding mechanism, the first battery can fully utilize the space of the first accommodation space, and the space utilization rate inside the second main body is relatively high.

[0028] In a possible implementation, the first battery includes a first surface facing the second back cover, and at least part of the first surface of the first battery is in a stepped shape or a wedge shape.

[0029] It can be understood that since at least part of the first surface of the first battery is in a stepped shape or a wedge shape, the first battery can fully utilize the space of the first accommodation space, and the space utilization rate inside the second main body is relatively high. In this way, under the premise that the thickness of the electronic device in the first closed state is reduced, the capacity of the first battery is not easily affected, so that the endurance of the electronic device is not easily affected.

[0030] In a possible implementation, the second main body further includes a second battery and a structural member, the second battery is located in the first accommodation space and is fixedly connected with the second middle frame, the second battery and the second back cover enclose a second accommodation space, the thickness of the second accommodation space is reduced in the direction away from the first folding mechanism, and at least part of the structural member is located in the second accommodation space.

[0031] It can be understood that the second battery can be located inside the second main body, and the structural member can be arranged in the second accommodation space, so that the space utilization rate inside the second main body is relatively high. In addition, the present embodiment can not need to reduce the thickness of the second battery to make room for accommodating the structural member, so that the capacity of the second battery is not easily reduced, and the endurance of the electronic device is not easily reduced.

[0032] In a possible implementation, the structural member is a cross-board circuit board; the second main body further includes a first circuit board and a second circuit board, both of which are located in the second accommodating space and on two sides of the second battery, and both of which are fixedly connected with the second middle frame; the cross-board circuit board is connected with and electrically connected with the first circuit board and the second circuit board.

[0033] It can be understood that the cross-board circuit board can make full use of the space of the second accommodating space, and the space utilization inside the second main body is high. Therefore, the embodiment can not need to leave out space for accommodating the cross-board circuit board by reducing the thickness of the second battery, and the capacity of the second battery is not easily reduced, so that the endurance of the electronic device is not easily reduced.

[0034] In an embodiment, the cross-board circuit board can be located between the second battery and the second middle frame of the second shell, and the second battery is fixedly connected with the second middle frame of the second shell through the cross-board circuit board. In this way, the distance between the second battery and the second middle frame of the second shell is large, and the distance between the second battery and the second back cover of the second shell is small. In this way, the embodiment needs to leave out space for accommodating the cross-board circuit board by reducing the thickness of the second battery 26, and the capacity of the second battery will be reduced with the reduction of the thickness, so that the endurance of the electronic device is reduced.

[0035] It can be understood that, compared with the embodiment in which the cross-board circuit board is located between the second battery and the second middle frame, in the embodiment, since the cross-board circuit board is located between the second battery and the second back cover of the second shell, the distance between the second battery and the second middle frame is small, and the distance between the second battery and the second back cover of the second shell is large. In other words, there is a large space between the second battery and the second back cover of the second shell, and the embodiment can not need to leave out space for accommodating the cross-board circuit board by reducing the thickness of the second battery, and the capacity of the second battery can not be negatively affected. Therefore, under the premise of thinning the thickness of the electronic device in the first closed state, the capacity of the second battery and the endurance of the electronic device are not easily affected. Therefore, the scheme of the embodiment can not only achieve the thinning of the thickness of the electronic device in the first closed state, but also not easily reduce the endurance of the electronic device. In other words, the electronic device of the embodiment can balance the thin thickness and the good endurance.

[0036] In a possible implementation, the structural member is a wireless charging circuit board, the wireless charging circuit board is located in the second accommodating space, and the wireless charging circuit board is fixedly connected with the second back cover; the thickness of the wireless charging circuit board decreases in a direction away from the first folding mechanism.

[0037] It can be understood that the wireless charging circuit board can make full use of the space of the second accommodating space, and the space utilization inside the second main body is high. Therefore, the present embodiment can not need to leave space by reducing the thickness of the second battery to accommodate the wireless charging circuit board, and the capacity of the second battery is not easily reduced, thereby not easily affecting the endurance of the electronic device.

[0038] In a possible implementation, the second main body further includes a third circuit board, the third circuit board is located at a side of the second battery away from the second rear cover of the second shell, and is fixedly connected with the second battery.

[0039] It can be understood that the third circuit board can not need to occupy the space of the second accommodating space, and the present embodiment can not need to leave space by reducing the thickness of the wireless charging circuit board to accommodate the third circuit board, and the charging efficiency of the wireless charging circuit board can not be easily reduced.

[0040] In a possible implementation, the second main body further includes a first heat spreader, the first heat spreader is located at a side of the second battery away from the second rear cover, and is fixedly connected with the second battery; a surface of the first heat spreader facing the second battery is provided with a recess, and at least part of the third circuit board is located in the recess.

[0041] It can be understood that by arranging the third circuit board in the recess of the first heat spreader, the space along the second direction of the second main body can be fully utilized, and the space utilization inside the second main body is improved. Therefore, the present embodiment can not need to leave space by reducing the thickness of the second battery to accommodate the third circuit board, and the capacity of the second battery is not easily reduced, thereby not easily affecting the endurance of the electronic device.

[0042] In an embodiment, the thickness of the second main body can remain substantially unchanged in the direction away from the first folding mechanism, and the thickness of the wireless charging circuit board can also remain substantially unchanged. The third circuit board can be located between the wireless charging circuit board and the second battery. The first heat spreader can be located at a side of the second battery away from the wireless charging circuit board and the third circuit board. In this way, the space utilization of the second main body along the second direction is low.

[0043] It can be understood that, compared with the previous embodiment, in the present embodiment, by arranging the third circuit board and the wireless charging circuit board on the two sides of the second battery respectively, and arranging the third circuit board in the groove of the first vapor chamber, the space utilization of the second main body in the second direction is higher. In addition, under the premise of thinning the thickness of the electronic device in the first closed state, the third circuit board can not need to occupy additional space in the second direction, and the present embodiment can not need to release space by reducing the thickness of the second battery to accommodate the third circuit board, and the capacity of the second battery can not be easily reduced. Therefore, the scheme of the present embodiment can not only realize the thinning of the thickness of the electronic device in the first closed state, but also can not easily reduce the wireless charging performance and the endurance of the electronic device.

[0044] In a possible implementation, the structural member is a second vapor chamber, the second vapor chamber is located in the second accommodating space, and the second vapor chamber is fixedly connected with the second battery; and the thickness of the second vapor chamber decreases in a direction away from the first folding mechanism.

[0045] It can be understood that the second vapor chamber can make full use of the space of the second accommodating space, and the space utilization inside the second main body is higher. Therefore, the present embodiment can not need to release space by reducing the thickness of the second battery to accommodate the second vapor chamber, and the capacity of the second battery is not easily reduced, so as to not easily reduce the endurance of the electronic device.

[0046] In an embodiment, the thickness of the second main body can remain substantially unchanged, and the thickness of the second vapor chamber can also remain substantially unchanged. In this way, the electronic device cannot realize the thinning of the thickness.

[0047] It can be understood that, compared with the previous embodiment, in the present embodiment, under the premise of thinning the thickness of the electronic device in the first closed state, the second vapor chamber can make full use of the space of the second accommodating space, and the heat dissipation efficiency of the second vapor chamber is not easily significantly reduced. Therefore, the scheme of the present embodiment can not only realize the thinning of the electronic device in the first closed state, but also can not easily reduce the heat dissipation performance of the electronic device. In other words, the electronic device of the present embodiment can balance the relatively thin thickness and the relatively good heat dissipation performance.

[0048] In a possible implementation, the second main body further includes a fourth circuit board and a heightening plate, the fourth circuit board is located in the first accommodating space and is fixedly connected with the second middle frame; the fourth circuit board and the second back cover enclose a third accommodating space, the thickness of the third accommodating space decreases in a direction away from the first folding mechanism, and the heightening plate is located in the third accommodating space and is fixedly connected with the fourth circuit board.

[0049] It can be understood that the heightening plate can make full use of the space of the third accommodating space, and can improve the space utilization inside the second main body.

[0050] In a possible implementation, the second main body further includes a fourth circuit board and a device, the fourth circuit board is located in the first accommodating space and fixedly connected with the second middle frame; the fourth circuit board and the second back cover enclose a third accommodating space, the thickness of the third accommodating space decreases along the direction away from the first folding mechanism, and the device is located in the third accommodating space and fixedly connected with the fourth circuit board.

[0051] It can be understood that the device can fully utilize the space of the third accommodating space, and the space utilization rate inside the second main body can be improved.

[0052] In a possible implementation, the second shell includes a second middle frame and a second back cover, and the third display area and the second back cover are fixedly connected to two sides of the second middle frame respectively; the second back cover includes a first surface facing away from the second middle frame, and the first surface of the second back cover approaches the second middle frame along the direction away from the first folding mechanism.

[0053] It can be understood that, by arranging the first surface of the second back cover to approach the second middle frame along the direction away from the first folding mechanism, the thickness of the second back cover of the second shell can decrease along the direction away from the first folding mechanism, so that the thickness of the second main body can also decrease along the direction away from the first folding mechanism. In this way, the structure for thinning the thickness of the second main body is relatively simple, and the process is relatively easy.

[0054] In a possible implementation, the first shell includes a first middle frame and a first back cover; the first middle frame includes a first surface and a second surface arranged oppositely, and the first display area is fixedly connected to the first surface of the first middle frame; the first back cover is fixedly connected to the second surface of the first middle frame, and a surface of the first back cover away from the first middle frame is a first lower surface of the first main body; and the second surface of the first middle frame approaches the first surface of the first middle frame along the direction away from the first folding mechanism.

[0055] It can be understood that, by arranging the second surface of the first middle frame to approach the first surface of the first middle frame along the direction away from the first folding mechanism, the thickness of the first shell can decrease along the direction away from the first folding mechanism, so that the thickness of the first main body can also decrease along the direction away from the first folding mechanism. In this way, the structure for thinning the thickness of the first main body is relatively simple, and the process is relatively easy.

[0056] In a possible implementation, the first shell includes a first middle frame and a first back cover, and the first display area and the first back cover are fixedly connected to two sides of the first middle frame respectively; the first back cover includes a first surface facing away from the first middle frame, and the first surface of the first back cover approaches the first middle frame along the direction away from the first folding mechanism.

[0057] It can be understood that, by setting the first surface of the first back cover to be close to the first middle frame in a direction away from the first folding mechanism, the thickness of the first back cover can be reduced in the direction away from the first folding mechanism, so that the thickness of the first shell can be reduced in the direction away from the first folding mechanism, and thus the thickness of the first main body can be reduced in the direction away from the first folding mechanism. In this way, the structure for reducing the thickness of the first main body is relatively simple, and the process is relatively easy.

[0058] In a possible implementation, the electronic device includes a first shell, a second shell, a third shell, a first display screen, and a second display screen. The first display screen includes a first display area, a second display area, a third display area, a fourth display area, and a fifth display area connected in sequence. The first display area is fixedly connected to the first shell, the third display area is fixedly connected to the second shell, and the fifth display area is fixedly connected to the third shell. The second display area is arranged opposite to the first folding mechanism and is capable of being folded, and the fourth display area is arranged opposite to the second folding mechanism and is capable of being folded. The second display screen is fixedly connected to the first shell and is located on a side of the first shell away from the first display area. A surface of the first display area away from the first shell is a first upper surface of a first main body, a surface of the second display screen away from the first display area is a first lower surface of the first main body, a surface of the third display area away from the second shell is a second upper surface of a second main body, a surface of the second shell away from the third display area is a second lower surface of the second main body, a surface of the fifth display area away from the third shell is a third upper surface of a third main body, and a surface of the third shell away from the fifth display area is a third lower surface of the third main body.

[0059] It can be understood that, since the electronic device is in the first closed state, the first main body, the third main body, and the second main body can be arranged in the second direction, and the first upper surface can be arranged opposite to the third lower surface, and the second upper surface can be arranged opposite to the third upper surface. Then, the first lower surface and the second lower surface can be located on the outer side of the electronic device, and the first upper surface, the second upper surface, the third upper surface, and the third lower surface can be located on the inner side of the electronic device. The first display screen can be located on the inner side of the electronic device, and the first main body, the second main body, and the third main body can protect the first display screen and prevent the first display screen from being scratched. The second display screen can be located on the outer side of the electronic device, and the user can use the second display screen of the electronic device when the electronic device is in the first closed state. In this way, the electronic device can have the function of displaying images when the electronic device is in the flat state or the first closed state, and the user experience is better.

[0060] In a possible implementation, the first main body includes a first connecting piece and a second connecting piece, and the second display screen is fixedly connected with the first middle frame of the first shell in sequence through the first connecting piece and the second connecting piece; and the first connecting piece is formed on the edge of the second display screen through a low-injection-pressure overmolding process. It can be understood that, in an embodiment, the first shell needs to be provided with a step, and the second display screen is fixedly connected with the step of the first shell through the second connecting piece, so as to realize the fixed connection between the second display screen and the first shell. In this way, when the second display screen displays an image, the black border of the second display screen is wider, the display area of the second display screen is smaller, and the visual experience of the user is poorer.

[0061] It can be understood that, compared with the embodiment in which the step needs to be provided to realize the fixed connection between the second display screen and the first shell, the scheme of realizing the fixed connection between the second display screen and the first shell by providing the first connecting piece and the second connecting piece in the embodiment does not need to provide the step. In this way, when the second display screen displays an image, the black border of the second display screen is narrower, the display area of the second display screen is larger, and the use experience of the user is better. Since the first connecting piece needs to occupy the space in the thickness direction of the first shell, the thickness of the first connecting piece is larger, and the embodiment can improve the space utilization of the first shell by arranging the first connecting piece in the region with a larger thickness of the first receiving space.

[0062] In a possible implementation, the first connecting piece is a heat-cured glue or a UV-cured glue.

[0063] It can be understood that the first connecting piece can be firmly bonded with the second display screen and the second connecting piece, and the cooperation between the first connecting piece and the second connecting piece can ensure that the second display screen is not prone to displacement or falling off, which is beneficial to maintaining the stability of the second display screen.

[0064] In a possible implementation, the second connecting piece is a pressure-sensitive adhesive. It can be understood that the second connecting piece can be firmly bonded with the second display screen, the first middle frame and the first connecting piece, and the cooperation between the first connecting piece and the second connecting piece can ensure that the second display screen is not prone to displacement or falling off, which is beneficial to maintaining the stability of the second display screen.

[0065] In a possible implementation, the third shell includes a third middle frame and a third back cover; the third middle frame includes oppositely arranged first and second surfaces, and the fifth display area is fixedly connected with the first surface of the third middle frame; the third back cover is fixedly connected with the second surface of the third middle frame, and the surface of the third back cover away from the third middle frame is the third lower surface of the third main body; and the second surface of the third middle frame is closer to the first surface of the third middle frame in a direction away from the second folding mechanism.

[0066] It can be understood that by setting the second surface of the third middle frame to be close to the first surface of the third middle frame in a direction away from the second folding mechanism, the thickness of the third shell can be reduced in the direction away from the second folding mechanism, so that the thickness of the third main body can also be reduced in the direction away from the second folding mechanism. In this way, the structure for reducing the thickness of the third main body is relatively simple, and the process is relatively easy. BRIEF DESCRIPTION OF DRAWINGS

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

[0093] In the description of the present application, it should be noted that unless otherwise specified and limited, the terms "mounting", "connection", "connecting", "joint" should be understood in a broad sense, for example, "connecting" can be detachable connection or non-detachable connection; can be direct connection or indirect connection through intermediate medium; can be electrical connection or mechanical connection. Among them, "fixed connection" refers to the connection of each other and the relative position relationship after connection does not change. The relative arrangement of component A and component B can be that component A projects to obtain projection C along the target direction, component B projects to obtain projection D along the target direction, and projection C and projection D can at least mostly overlap. In some embodiments, the mostly overlap can be any of the following cases: projection C is completely located in projection D. Or, projection D is completely located in projection C. Or, projection C and projection D intersect with each other, and the intersection area of projection C and projection D accounts for more than 50% of projection C or projection D.

[0094] The orientation terms mentioned in the embodiments of the present application, such as "inner", "outer" and the like, are only the directions of the drawings, therefore, the orientation terms used are for better and clearer illustration and understanding of the embodiments of the present application, and are not intended to indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the embodiments of the present application. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to the specific circumstances.

[0095] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship. "Multiple" means at least two.

[0096] In addition, in the embodiments of the present application, the relative position relationship mentioned, such as parallel, perpendicular, etc. These limits are for the current process level, not an absolute strict limit, and a small amount of deviation is allowed, approximately parallel, approximately perpendicular, etc. For example, A is parallel to B, which means that A and B are parallel or approximately parallel, and the included angle between A and B can be between 0 degrees and 10 degrees. For example, A is perpendicular to B, which means that A and B are perpendicular or approximately perpendicular, and the included angle between A and B can be between 80 degrees and 100 degrees.

[0097] FIG. 1 is a structural schematic diagram of an electronic device 1000 according to an embodiment of the present application.

[0098] As shown in FIG. 1, the electronic device 1000 can be a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a camera, a personal computer, a notebook computer, a vehicle-mounted device, a wearable device, augmented reality (AR) glasses, AR helmet, virtual reality (VR) glasses, or VR helmet, etc. The electronic device 1000 according to the embodiments of the present application is exemplarily described as a mobile phone. It can be understood that the number of folds of the electronic device 1000 is not limited to two as shown in FIG. 1. In other embodiments, the number of folds of the electronic device 1000 can be greater than two.

[0099] It can be understood that, for the convenience of description hereinafter, the extension direction of the rotation axis of the electronic device 1000 is exemplarily defined as the Y-axis direction, that is, the width direction of the electronic device 1000 is the Y-axis direction. The thickness direction of the electronic device 1000 is the Z-axis direction. The length direction of the electronic device 1000 is the X-axis direction. Exemplarily, the X-axis direction is defined as a first direction, the Z-axis direction is defined as a second direction, and the Y-axis direction is defined as a third direction, which can be different from each other. In other embodiments, the first direction, the second direction, and the third direction can be flexibly set according to requirements, as long as the first direction, the second direction, and the third direction are different.

[0100] It can be understood that the coordinate system of the electronic device 1000 can also be flexibly set according to specific requirements. In the present embodiment, when the direction of the rotation axis of the electronic device 1000 is the third direction, the electronic device 1000 can be unfolded or folded relative to the third direction. In this way, when the electronic device 1000 is in the first closed state, the size of the electronic device 1000 in the first direction is reduced.

[0101] FIG. 2 is a partial structural schematic diagram of an embodiment of the electronic device 1000 shown in FIG. 1 in a flat state. FIG. 3 is a partial structural schematic diagram of an embodiment of the electronic device 1000 shown in FIG. 1 in a first closed state.

[0102] As shown in FIGS. 1-3, the electronic device 1000 can include, for example, a first body 100, a second body 200, a third body 300, a first folding mechanism 410, and a second folding mechanism 420. It can be understood that FIGS. 1-3 and the following related drawings only schematically show some components included in the electronic device 1000, and the actual shape, actual size, actual position, and actual structure of these components are not limited by FIGS. 1-3 and the following drawings. In other embodiments, the electronic device 1000 can include more or fewer structures. For example, when the electronic device 1000 includes more structures, the electronic device 1000 can further include a screen decoration (not shown).

[0103] The first folding mechanism 410 can connect the first body 100 and the second body 200. The first folding mechanism 410 can be used to unfold or fold the first body 100 and the second body 200 relative to each other. The second folding mechanism 420 can connect the second body 200 and the third body 300. The second folding mechanism 420 can be used to unfold or fold the second body 200 and the third body 300 relative to each other. It can be understood that in this application, by providing the first folding mechanism 410 and the second folding mechanism 420 in the electronic device 1000, the electronic device 1000 can achieve multiple folding.

[0104] As shown in FIGS. 2 and 3, the first body 100 can include a first upper surface 11 and a first lower surface 12 arranged oppositely. The second body 200 can include a second upper surface 21 and a second lower surface 22 arranged oppositely. The third body 300 can include a third upper surface 31 and a third lower surface 32 arranged oppositely.

[0105] When the electronic device 1000 is in a flat state, the first body 100, the second body 200, and the third body 300 can be arranged along a first direction. In an embodiment, the first upper surface 11, the second upper surface 21, and the third upper surface 31 can be located in the same plane. It can be understood that being located in the same plane can refer to the case where the first upper surface 11, the second upper surface 21, and the third upper surface 31 are coplanar, or can refer to the case where there is an included angle between the first upper surface 11, the second upper surface 21, and the third upper surface 31, in other words, being located in the same plane can also allow some slight deviation, and can not be strictly coplanar. In addition, being located in the same plane appearing again below represents the same meaning, which will not be repeated.

[0106] Referring to FIG. 3, and in combination with FIG. 2, the first lower surface 12 can be closer to the first upper surface 11 in a direction away from the first folding mechanism 410. The first main body 100 can be substantially wedge-shaped. The second lower surface 22 can be closer to the second upper surface 21 in a direction away from the first folding mechanism 410. The second main body 200 can be substantially wedge-shaped. The third lower surface 32 can be closer to the third upper surface 31 in a direction away from the second folding mechanism 420. The third main body 300 can be substantially wedge-shaped.

[0107] As shown in FIG. 3, when the electronic device 1000 is in the first closed state, the first main body 100, the second main body 200, and the third main body 300 can be arranged in the second direction. The first upper surface 11 can be opposite to the third lower surface 32, and the second upper surface 21 can be opposite to the third upper surface 31.

[0108] As shown in FIG. 2 and FIG. 3, the first lower surface 12 can be closer to the first upper surface 11 in a direction away from the first folding mechanism 410. The first upper surface 11 can be closer to the first lower surface 12 in a direction away from the first folding mechanism 410. The third lower surface 32 can be closer to the third upper surface 31 in a direction away from the first folding mechanism 410. The second lower surface 22 can be closer to the second upper surface 21 in a direction away from the second folding mechanism 420.

[0109] FIG. 4 is a structural schematic diagram of an embodiment of the electronic device 1000 shown in FIG. 1 in a second closed state.

[0110] As shown in FIG. 4, the electronic device 1000 can also be in any state between the flat state and the first closed state, which can be referred to as an intermediate state. In an embodiment, the intermediate state can include the second closed state. When the electronic device 1000 is in the second closed state, the second main body 200 and the third main body 300 can be closer to each other. The first main body 100 and the second main body 200 can be arranged in the first direction, and the second main body 200 and the third main body 300 can be arranged in the second direction.

[0111] As shown in FIG. 4, the third upper surface 31 can be opposite to the second upper surface 21. The third lower surface 32 can be closer to the third upper surface 31 in a direction away from the first folding mechanism 410. The second lower surface 22 can be closer to the second upper surface 21 in a direction away from the second folding mechanism 420.

[0112] FIG. 5 is a partial exploded schematic diagram of an embodiment of the electronic device 1000 shown in FIG. 1.

[0113] As shown in FIG. 5, the second body 200 may, for example, include a camera module 23. The camera module 23 may be configured to implement image capturing.

[0114] The second body 200 may, for example, be provided with a mounting hole 24. The mounting hole 24 may be formed to open at the second lower surface 22.

[0115] Referring to FIG. 5, in combination with FIG. 3, the electronic device 1000 may, for example, further include a camera decoration 500. The camera decoration 500 may be fixedly connected with the second body 200, and cover the mounting hole 24 and the camera module 23 of the second body 200. It can be understood that FIG. 5 and the relevant drawings below only schematically show some components included in the electronic device 1000, and the actual shape, actual size, actual position and actual structure of these components are not limited by FIG. 5 and the drawings below.

[0116] As shown in FIG. 5, the camera decoration 500 may, for example, include a first surface 51 arranged opposite to the second lower surface 22.

[0117] Referring to FIG. 3, in combination with FIG. 5, when the electronic device 1000 is in the first closed state, the angle a between the first surface 51 of the camera decoration 500 and the first lower surface 12 may, for example, satisfy 0°≤a≤10°, for example, a may be equal to 0°, 3°, 5°, 6°, 8° or 10°.

[0118] It can be understood that by setting the angle a between the first surface 51 of the camera decoration 500 and the first lower surface 12 within the range of 0° to 10°, when the electronic device 1000 is in the first closed state, the first surface 51 of the camera decoration 500 and the first lower surface 12 of the first body 100 may be substantially parallel. When a user places the electronic device 1000 in the first closed state on a plane such as a table, the first surface 51 of the camera decoration 500 may be in contact with the plane such as a table, and the first lower surface 12 of the first body 100 may be substantially parallel to the plane such as a table. In this way, while achieving the thinness of the electronic device 1000, the electronic device 1000 in the first closed state can be placed more regularly on the plane such as a table, and the electronic device 1000 has a higher degree of delicacy. In addition, when a user uses the electronic device 1000 in the first closed state to take a photo, the first surface 51 of the camera decoration 500 and the first lower surface 12 of the first body 100 may be substantially perpendicular to the user's line of sight, and the camera module 23 can facilitate image capturing, and the user has a better use experience.

[0119] In other embodiments, the angle b between the first surface 51 of the camera decoration 500 and the first lower surface 12 may also satisfy other ranges.

[0120] Referring to FIG. 3, and in combination with FIG. 5, the angle b between the first surface 51 of the camera decoration 500 and the second lower surface 22 can satisfy 0°≤b≤10° when the electronic device 1000 is in the first closed state, for example, b can be equal to 0°, 3°, 5°, 6°, 8°, and 10°, etc.

[0121] It can be understood that by setting the angle b between the first surface 51 of the camera decoration 500 and the second lower surface 22 in the range of 0° to 10°, when the electronic device 1000 is in the first closed state, the first surface 51 of the camera decoration 500 and the second lower surface 22 of the second main body 200 can be substantially parallel.

[0122] The foregoing describes the general structure of the electronic device 1000 in combination with the related drawings, and specifically describes the form of the electronic device 1000 in the unfolded state, the first closed state, and the second closed state. It can be understood that the electronic device 1000 can have a large-screen display effect in the unfolded state. However, the thickness of the electronic device 1000 in the first closed state is large, so how to reduce the thickness of the electronic device 1000 in the first closed state becomes an important factor for users to concern. Hereinafter, a scheme for reducing the thickness of the electronic device 1000 will be described in combination with the related drawings.

[0123] FIG. 6 is a structural schematic diagram of the electronic device 1000 shown in FIG. 1 in another embodiment. FIG. 7 is a structural schematic diagram of the electronic device 1000 shown in FIG. 6 in the first closed state.

[0124] As shown in FIGS. 6 and 7, the electronic device 1000 can include a first main body 101, a second main body 201, a third main body 301, a first folding mechanism 411, and a second folding mechanism 421.

[0125] Exemplarily, the first folding mechanism 411 can connect the first main body 101 and the second main body 201. The first folding mechanism 411 can be used to unfold or fold the first main body 101 and the second main body 201 relative to each other. The second folding mechanism 421 can connect the second main body 201 and the third main body 301.

[0126] The second folding mechanism 421 can be used to unfold or fold the second main body 201 and the third main body 301 relative to each other.

[0127] Exemplarily, the first main body 101 can include a first upper surface 111 and a first lower surface 121 arranged oppositely. The second main body 201 can include a second upper surface 211 and a second lower surface 221 arranged oppositely. The third main body 301 can include a third upper surface 311 and a third lower surface 321 arranged oppositely.

[0128] Exemplarily, when the electronic device 1000 is in the unfolded state, the first body 101, the second body 201 and the third body 301 can be arranged along the first direction. In an embodiment, the first upper surface 111, the second upper surface 211 and the third upper surface 311 can be located in the same plane. The first lower surface 121, the second lower surface 221 and the third lower surface 321 can be located in the same plane.

[0129] Exemplarily, the first upper surface 111 can be substantially parallel to the first lower surface 121. The cross section of the first body 101 can be substantially rectangular. The second upper surface 211 can be substantially parallel to the second lower surface 221. The cross section of the second body 201 can be substantially rectangular. The third upper surface 311 can be substantially parallel to the third lower surface 321. The cross section of the third body 301 can be substantially rectangular.

[0130] As shown in FIG. 7, exemplarily, when the electronic device 1000 is in the first closed state, the first body 101, the third body 301 and the second body 201 can be arranged along the second direction. The first upper surface 111 and the third lower surface 321 can be oppositely arranged and substantially parallel. The second upper surface 211 and the third upper surface 311 can be oppositely arranged and substantially parallel.

[0131] It can be understood that the electronic device 1000 can have a large-screen display effect in the unfolded state. However, the electronic device 1000 shown in FIGS. 6 and 7 has the technical problem that the thickness of the electronic device 1000 in the first closed state is large.

[0132] In order to solve the technical problems mentioned above, the following will introduce a thickness reduction scheme of the electronic device 1000 in the first closed state in combination with the related drawings. Specifically as follows.

[0133] FIG. 8 is a partial structural schematic diagram of the electronic device 1000 shown in FIG. 1 in some embodiments. Exemplarily, FIG. 8 can be the structure of the electronic device 1000 shown in FIG. 7 after cutting along the dashed line M1-M1 and the dashed line M2-M2 on the first body 101 and the third body 301.

[0134] As shown in FIG. 8, exemplarily, the first upper surface 11 of the first body 100 can be close to the first lower surface 12 in a direction away from the first folding mechanism, and the third lower surface 32 of the third body 300 can be close to the third upper surface 31 in a direction away from the second folding mechanism 420. In this way, the first body 100 and the third body 300 in the embodiment can be spaced apart, and the first upper surface 11 of the first body 100 and the third lower surface 32 of the third body 300 can enclose a first moving space S1.

[0135] As shown in FIG. 3, the first upper surface 11 of the first body 100 can be closer to the first lower surface 12 in a direction away from the first folding mechanism, and the third lower surface 32 of the third body 300 can be closer to the third upper surface 31 in a direction away from the second folding mechanism 420. At this time, the first upper surface 11 of the first body 100 and the third lower surface 32 of the third body 300 can be closer to each other. Therefore, compared with the electronic device 1000 shown in FIG. 8, the electronic device 1000 shown in FIG. 3 can omit the first moving space S1, that is, compared with the electronic devices shown in FIGS. 6 and 7, the electronic device 1000 shown in FIG. 3 can be thinned when in the first closed state.

[0136] It can be understood that, as shown in FIG. 3, since the end of the first body 100 away from the first folding mechanism 410 is not easily limited by the first folding mechanism 410, and the end of the third body 300 away from the second folding mechanism 420 is not easily limited by the second folding mechanism 420, the present application can reduce the thickness of the end of the first body 100 away from the first folding mechanism 410 and the thickness of the end of the third body 300 away from the second folding mechanism 420, so that the first upper surface 11 of the first body 100 can be closer to the first lower surface 12 in a direction away from the first folding mechanism 410, and the third lower surface 32 of the third body 300 can be closer to the third upper surface 31 in a direction away from the second folding mechanism 420. In this way, through the cooperation of the first upper surface 11 of the first body 100 and the third lower surface 32 of the third body 300, the electronic device 1000 shown in FIG. 3 can be thinned when in the first closed state.

[0137] FIG. 9 is a partial structural schematic diagram of the electronic device 1000 shown in FIG. 1 in some embodiments. For example, FIG. 9 can be the structure of the electronic device 1000 shown in FIG. 8 after cutting along the dashed line M3-M3 and the dashed line M4-M4 on the second body 200 and the third body 300.

[0138] As shown in FIG. 9, for example, the second lower surface 22 of the second body 200 can be closer to the second upper surface 21 in a direction away from the first folding mechanism 410, and the third lower surface 32 of the third body 300 can be closer to the third upper surface 31 in a direction away from the second folding mechanism 420. In this way, the first body 100 and the third body 300 in the present embodiment can be spaced apart, and the first upper surface 11 of the first body 100 and the third lower surface 32 of the third body 300 can enclose the second moving space S2.

[0139] In combination with FIG. 3, the second lower surface 22 of the second body 200 can be closer to the second upper surface 21 in a direction away from the first folding mechanism 410, and the third lower surface 32 of the third body 300 can be closer to the third upper surface 31 in a direction away from the second folding mechanism 420. At this time, the first upper surface 11 of the first body 100 and the third lower surface 32 of the third body 300 can be closer to each other. Therefore, compared with the electronic device 1000 shown in FIG. 9, the electronic device 1000 shown in FIG. 3 can omit the second moving space S2, that is, compared with the electronic device shown in FIGS. 6 and 7, the electronic device 1000 shown in FIG. 3 can achieve a thin type when in the first closed state.

[0140] It can be understood that, in combination with FIG. 3, since the end of the second body 200 away from the first folding mechanism 410 is not easily limited by the first folding mechanism 410, and the end of the third body 300 away from the second folding mechanism 420 is not easily limited by the second folding mechanism 420, the present application can reduce the thickness of the end of the second body 200 away from the first folding mechanism 410 and the thickness of the end of the third body 300 away from the second folding mechanism 420, so that the second lower surface 22 of the second body 200 can be closer to the second upper surface 21 in a direction away from the first folding mechanism 410, and the third lower surface 32 of the third body 300 can be closer to the third upper surface 31 in a direction away from the second folding mechanism 420. In this way, through the cooperation of the first upper surface 11 of the first body 100, the second lower surface 22 of the second body 200 and the third lower surface 32 of the third body 300, the electronic device 1000 shown in FIG. 3 can achieve a thin type when in the first closed state.

[0141] In the present application, through the cooperation of the first upper surface 11 of the first body 100 and the third lower surface 32 of the third body 300, the cooperation of the first upper surface 11 of the first body 100, the second lower surface 22 of the second body 200 and the third lower surface 32 of the third body 300, the electronic device 1000 shown in FIG. 3 can achieve a thin type when in the first closed state. In particular, for some foldable electronic devices with a large screen bending angle, such as foldable electronic devices with a water drop screen. When the thinning method of the present application is used, the foldable electronic device can have enough space to accommodate the screen while effectively achieving the thinning of the foldable electronic device, thereby improving the user experience of the foldable electronic device.

[0142] FIG. 10 is a partially exploded schematic view of the electronic device 1000 shown in FIG. 1 in another embodiment.

[0143] As shown in FIG. 10, the electronic device 1000 can include the first housing 600, the second housing 700, the third housing 800, the first folding mechanism 410, the second folding mechanism 420, the first display screen 910, and the second display screen 920, for example. It can be understood that the electronic device 1000 can also include more or fewer structures. For example, when the electronic device 1000 includes more structures, the electronic device 1000 can also include a screen decoration (not shown in the figure). When the electronic device 1000 includes fewer structures, the electronic device 1000 can not include the second display screen 920.

[0144] Referring to FIG. 10, in combination with FIGS. 2 and 3, the first folding mechanism 410 can connect the first housing 600 and the second housing 700. The first folding mechanism 410 can be used to unfold or fold the first housing 600 and the second housing 700 relative to each other. The second folding mechanism 420 can connect the second housing 700 and the third housing 800. The second folding mechanism 420 can be used to unfold or fold the second housing 700 and the third housing 800 relative to each other. It can be understood that the first folding mechanism 410 can be an inner folding mechanism. The second folding mechanism 420 can be an inner folding mechanism. An inner folding mechanism refers to a folding mechanism that can fold at least part of the first display screen 910 between two housings.

[0145] In other embodiments, the first folding mechanism 410 can also be an outer folding mechanism. The second folding mechanism 420 can also be an outer folding mechanism. An outer folding mechanism refers to a folding mechanism that can fold at least part of the first display screen 910 outside the housing. The specific application is not limited.

[0146] In the present embodiment, the first folding mechanism 410 is an inner folding mechanism, and the second folding mechanism 420 is an inner folding mechanism, for example.

[0147] Referring to FIG. 10, in combination with FIG. 1, when the first housing 600, the second housing 700, the third housing 800, the first folding mechanism 410, and the second folding mechanism 420 are unfolded to a flat state, the electronic device 1000 is in an unfolded state. For example, when the electronic device 1000 is in a flat state, the first housing 600, the second housing 700, the third housing 800, the first folding mechanism 410, and the second folding mechanism 420 can be arranged along a first direction, and can be approximately 180° (allowing some deviation, such as 165°, 177°, or 185°, etc.).

[0148] Referring to FIG. 10, and in combination with FIG. 3, when the first housing 600, the second housing 700, the third housing 800, the first folding mechanism 410, and the second folding mechanism 420 are relatively folded to the first closed state, the electronic device 1000 is in the first closed state. Exemplarily, when the electronic device 1000 is in the first closed state, the first housing 600 and the third housing 800 can be close to each other, and the first housing 600 and the third housing 800 can be stacked in the thickness direction of the electronic device 1000; the second housing 700 and the third housing 800 can be close to each other, and the second housing 700 and the third housing 800 can be stacked in the thickness direction of the electronic device 1000, and the third housing 800 can be stacked between the first housing 600 and the second housing 700. At this time, the first housing 600, the third housing 800, and the second housing 700 can be arranged along the second direction. When the first housing 600 and the second housing 700 are converted from the second closed state to the first closed state, the first folding mechanism 410 can enclose the first accommodating space 4101. When the second housing 700 and the third housing 800 are converted from the flat state to the first closed state or the second closed state, the second folding mechanism 420 can enclose the second accommodating space 4201. It can be understood that the first folding mechanism 410 with different structures can have different shapes of the first accommodating space 4101. The second folding mechanism 420 with different structures can have different shapes of the second accommodating space 4201. The specific structure of the first folding mechanism 410 and the second folding mechanism 420 is not limited in the present application.

[0149] Referring to FIG. 10, and in combination with FIG. 4, when the first housing 600, the second housing 700, the third housing 800, the first folding mechanism 410, and the second folding mechanism 420 are relatively folded to the second closed state, the electronic device 1000 is in the second closed state. Exemplarily, when the electronic device 1000 is in the second closed state, the first housing 600, the second housing 700, and the first folding mechanism 410 can be arranged along the first direction, and can be approximately 180° (allowing some deviation, such as 165°, 177°, or 185°, etc.), the second housing 700 and the third housing 800 can be close to each other, and the second housing 700 and the third housing 800 can be stacked in the thickness direction of the electronic device 1000.

[0150] Referring to FIG. 10, and in combination with FIG. 1, the first display screen 910 can include a first display area 911, a second display area 912, a third display area 913, a fourth display area 914, and a fifth display area 915 connected in sequence. The second display area 912 can be connected between the first display area 911 and the third display area 913. The third display area 913 can be connected between the second display area 912 and the fourth display area 914. The fourth display area 914 can be connected between the third display area 913 and the fifth display area 915. Exemplarily, FIG. 1 and FIG. 2 both take the first display area 911, the second display area 912, the third display area 913, the fourth display area 914, and the fifth display area 915 arranged along a first direction as an example.

[0151] Referring to FIG. 1, and in combination with FIG. 10, the first display area 911 of the first display screen 910 can be fixedly connected with the first housing 600. The third display area 913 can be fixedly connected with the second housing 700. The fifth display area 915 can be fixedly connected with the third housing 800. The second display area 912 can be oppositely arranged with the first folding mechanism 410. The fourth display area 914 can be oppositely arranged with the second folding mechanism 420.

[0152] It can be understood that when the first folding mechanism 410 relatively unfolds or folds the first housing 600 and the second housing 700, the first housing 600 can drive the first display area 911 of the first display screen 910 to relatively unfold or fold the third display area 913, and the second housing 700 can drive the third display area 913 of the first display screen 910 to relatively unfold or fold the first display area 911. At this time, the second display area 912 of the first display screen 910 can be bent. When the second folding mechanism 420 relatively unfolds or folds the second housing 700 and the third housing 800, the second housing 700 can drive the third display area 913 of the first display screen 910 to relatively unfold or fold the fifth display area 915, and the third housing 800 can drive the fifth display area 915 of the first display screen 910 to relatively unfold or fold the third display area 913. At this time, the fourth display area 914 of the first display screen 910 can be bent.

[0153] As shown in FIG. 1, when the electronic device 1000 is in a flat state, the first display screen 910 can be in a flat state. Exemplarily, the first display area 911, the second display area 912, the third display area 913, the fourth display area 914, and the fifth display area 915 of the first display screen 910 can be substantially 180° (allowing slight deviation, for example, 165°, 177°, or 185°). At this time, the first display screen 910 has a continuous large-area display area, that is, the first display screen 910 can realize large-screen display, and the user experience is better.

[0154] Referring to FIG. 10, and in combination with FIG. 1, at least part of the first folding mechanism 410 can be used to support the second display area 912 of the first display screen 910, and at least part of the second folding mechanism 420 can be used to support the fourth display area 914 when the electronic device 1000 is in the unfolded state. In this way, when the second display area 912 and the fourth display area 914 of the first display screen 910 receive a pressing force, a squeezing force, or an impact force, etc., the first folding mechanism 410 and the second folding mechanism 420 can be used to improve the pressure resistance and impact resistance of the second display area 912 and the fourth display area 914, i.e., to ensure that the second display area 912 and the fourth display area 914 are not prone to problems such as denting.

[0155] As shown in FIG. 3, when the electronic device 1000 is in the first closed state, the first display screen 910 can be in a first closed state. Illustratively, the first display area 911 and the third display area 913 of the first display screen 910 can be arranged close to each other, and the third display area 913 and the fifth display area 915 of the first display screen 910 can be arranged close to each other. At this time, the first display area 911, the fifth display area 915, and the third display area 913 of the first display screen 910 can be arranged along the second direction. In addition, the second display area 912 and the fourth display area 914 of the first display screen 910 can be bent.

[0156] As shown in FIG. 3, illustratively, when the electronic device 1000 is in the first closed state, the first display area 911, the second display area 912, and the third display area 913 of the first display screen 910 can all be located between the first housing 600 and the second housing 700, and the second display area 912 can be located in the first accommodation space 4101 of the first folding mechanism 410, and the second display area 912 can be substantially in the shape of a "U", a water drop, or other shapes. The third display area 913, the fourth display area 914, and the fifth display area 915 of the first display screen 910 can all be located between the second housing 700 and the third housing 800, and the fourth display area 914 can be located in the second accommodation space 4201 of the second folding mechanism 420, and the fourth display area 914 can be substantially in the shape of a "U", a water drop, or other shapes.

[0157] When the electronic device 1000 is in the first closed state, since the first display area 911, the second display area 912, and the third display area 913 of the first display screen 910 are all located between the first housing 600 and the second housing 700, the display surface of the first display area 911 can face the display surface of the third display area 913, the second display area 912 can be foldably arranged between the first display area 911 and the third display area 913, and the second display area 912 can be located in the first accommodating space 4101 of the first folding mechanism 410. Since the third display area 913, the fourth display area 914, and the fifth display area 915 of the first display screen 910 are all located between the second housing 700 and the third housing 800, the display surface of the third display area 913 can face the display surface of the fifth display area 915, the fourth display area 914 can be foldably arranged between the third display area 913 and the fifth display area 915, and the fourth display area 914 can be located in the second accommodating space 4201 of the second folding mechanism 420. The first display area 911, the second display area 912, the third display area 913, the fourth display area 914, and the fifth display area 915 of the first display screen 910 can be referred to as inner screens of the electronic device 1000. When the first housing 600 and the second housing 700 are folded, the first display area 911, the second display area 912, and the third display area 913 of the first display screen 910 can be folded into the space formed by the first housing 600, the second housing 700, and the first folding mechanism 410, and the first display area 911, the second display area 912, and the third display area 913 can thus be referred to as inner screens of the electronic device 1000. When the second housing 700 and the third housing 800 are folded, the third display area 913, the fourth display area 914, and the fifth display area 915 of the first display screen 910 can be folded into the space formed by the second housing 700, the third housing 800, and the second folding mechanism 420, and the third display area 913, the fourth display area 914, and the fifth display area 915 can thus be referred to as inner screens of the electronic device 1000.

[0158] As shown in FIG. 4, when the electronic device 1000 is in the second closed state, the first display screen 910 can be in the second closed state. At least part of the first display area 911 and the second display area 912 of the first display screen 910 can be located outside the electronic device 1000. At this time, at least part of the first display area 911 and the second display area 912 of the first display screen 910 can be folded as an outer screen of the electronic device 1000. Illustratively, the first display area 911 and the second display area 912 of the first display screen 910 can be approximately 180° (allowing for slight deviations, such as 165°, 177°, or 185°). The third display area 913 and the fifth display area 915 of the first display screen 910 can be arranged close to each other. At this time, the third display area 913 and the fifth display area 915 of the first display screen 910 can be arranged in the second direction. At this time, the fourth display area 914 of the first display screen 910 can be bent.

[0159] Referring to FIG. 2, in combination with FIG. 10, illustratively, the second display screen 920 can be fixedly connected with the first housing 600. The second display screen 920 can be located on a side of the first housing 600 away from the first display screen 910. It can be understood that the second display screen 920 can not be bent when the electronic device 1000 is folded.

[0160] As shown in FIG. 3, when the electronic device 1000 is in the first closed state, the first display area 911, the second display area 912, the third display area 913, the fourth display area 914, and the fifth display area 915 can be located inside the electronic device 1000, and the second display screen 920 can be located outside the electronic device 1000. The first display area 911, the second display area 912, the third display area 913, the fourth display area 914, and the fifth display area 915 can thus be referred to as an inner screen of the electronic device 1000, and the second display screen 920 can thus be referred to as an outer screen of the electronic device 1000.

[0161] As shown in FIG. 1 and FIG. 3, for example, the first housing 600, the first display area 911, at least part of the second display area 912, and the second display screen 920 can constitute the first body 100 in the foregoing. At this time, the surface of the first display area 911 of the first display screen 910 away from the first housing 600 can be the first upper surface 11 of the first body 100 in the foregoing, and the surface of the second display screen 920 away from the first housing 600 can be the first lower surface 12 in the foregoing. The second housing 700, at least part of the second display area 912, the third display area 913, and at least part of the fourth display area 914 can constitute the second body 200 in the foregoing. At this time, the surface of the third display area 913 of the first display screen 910 away from the second housing 700 can be the second upper surface 21 of the second body 200 in the foregoing, and the surface of the second housing 700 away from the third display area 913 can be the second lower surface 22 of the second body 200 in the foregoing. The third housing 800, at least part of the fourth display area 914, and the fifth display area 915 can constitute the third body 300 in the foregoing. At this time, the surface of the fifth display area 915 of the first display screen 910 away from the third housing 800 can be the third upper surface 31 of the third body 300 in the foregoing, and the surface of the third housing 800 away from the fifth display area 915 can be the third lower surface 32 of the third body 300 in the foregoing.

[0162] It can be understood that, since the electronic device 1000 is in the first closed state, the first body 100, the third body 300, and the second body 200 can be arranged along the second direction, and the first upper surface 11 can be arranged opposite to the third lower surface 32, and the second upper surface 21 can be arranged opposite to the third upper surface 31, then the first lower surface 12 and the second lower surface 22 can be located on the outside of the electronic device 1000, and the first upper surface 11, the second upper surface 21, the third upper surface 31, and the third lower surface 32 can be located on the inside of the electronic device 1000, and the first display screen 910 can be located on the inside of the electronic device 1000, and the first body 100, the second body 200, and the third body 300 can play a role in protecting the first display screen 910 and preventing the first display screen 910 from being scratched. The second display screen 920 can be located on the outside of the electronic device 1000, and the user can use the second display screen 920 of the electronic device 1000 when the electronic device 1000 is in the first closed state. In this way, the electronic device 1000 can have the function of displaying images when the electronic device 1000 is in the flat state or the first closed state, and the user's experience is better.

[0163] As shown in FIG. 3, exemplary, the thickness of the end of the first body 100 close to the first folding mechanism 410 is defined as a first thickness A1. Wherein, the first thickness A1 can be the distance between the first upper surface 11 and the first lower surface 12 along the second direction at the end of the first body 100 close to the first folding mechanism 410, that is, the first thickness A1 can also be the distance between the surface of the second display area 912 of the first display screen 910 away from the first housing 600 and the surface of the second display screen 920 away from the first housing 600 along the second direction at the end of the first body 100 close to the first folding mechanism 410.

[0164] In other embodiments, the first thickness A1 can also be defined in other ways when the electronic device 1000 does not provide the second display screen 920. Specifically, the present application is not limited.

[0165] Exemplary, the thickness of the end of the first body 100 away from the first folding mechanism 410 is defined as a second thickness A2. Wherein, the second thickness A2 can be the distance between the first upper surface 11 and the first lower surface 12 along the second direction at the end of the first body 100 away from the first folding mechanism 410, that is, the second thickness A2 can also be the distance between the surface of the first display area 911 of the first display screen 910 away from the first housing 600 and the surface of the second display screen 920 away from the first housing 600 along the second direction at the end of the first body 100 away from the first folding mechanism 410.

[0166] In other embodiments, the second thickness A2 can also be defined in other ways when the electronic device 1000 does not provide the second display screen 920. Specifically, the present application is not limited.

[0167] Exemplary, the first thickness A1 and the second thickness A2 can satisfy: A1≠A2. Wherein, the first thickness A1 is not equal to the second thickness A2 due to non-processing assembly tolerance. In an embodiment, the thickness of the first body 100 can decrease in the direction away from the first folding mechanism 410.

[0168] Exemplary, the first thickness A1 and the second thickness A2 can satisfy: A1>A2. In this way, the thickness of the end of the first body 100 close to the first folding mechanism 410 is larger, the width of the first folding mechanism 410 can not need to be reduced, the reliability of the first folding mechanism 410 is higher, and the reliability of the electronic device 1000 is higher.

[0169] Exemplary, the first thickness A1 and the second thickness A2 can satisfy: A1-A2≥0.15mm (millimeter), for example, A1-A2 can be equal to 0.15mm, 0.2mm, 0.3mm, 0.5mm, 1mm or 2mm, etc.

[0170] In an embodiment, the difference between the first thickness A1 and the second thickness A2 can also be greater than or equal to other values. In other embodiments, the difference between the first thickness A1 and the second thickness A2 can also satisfy other ranges. The specific application is not limited.

[0171] As shown in FIG. 3, for example, the thickness of the end of the second body 200 close to the first folding mechanism 410 is defined as a third thickness B1. The third thickness B1 can be the distance between the second upper surface 21 and the second lower surface 22 in the second direction at the end of the second body 200 close to the first folding mechanism 410, that is, the third thickness B1 can also be the distance between the surface of the third display area 913 of the first display screen 910 away from the second housing 700 and the surface of the second housing 700 away from the third display area 913 of the first display screen 910 in the second direction at the end of the second body 200 close to the first folding mechanism 410.

[0172] In other embodiments, the third thickness B1 can also be defined in other ways. The specific application is not limited.

[0173] For example, the thickness of the end of the second body 200 away from the first folding mechanism 410 is defined as a fourth thickness B2. The fourth thickness B2 can be the distance between the second upper surface 21 and the second lower surface 22 in the second direction at the end of the second body 200 away from the first folding mechanism 410, that is, the fourth thickness B2 can also be the distance between the surface of the third display area 913 of the first display screen 910 away from the second housing 700 and the surface of the second housing 700 away from the third display area 913 of the first display screen 910 in the second direction at the end of the second body 200 away from the first folding mechanism 410.

[0174] In other embodiments, the fourth thickness B2 can also be defined in other ways. The specific application is not limited.

[0175] For example, the third thickness B1 and the fourth thickness B2 can satisfy: B1≠B2. The third thickness B1 and the fourth thickness B2 are not equal due to non-processing assembly tolerances. In an embodiment, the thickness of the second body 200 can decrease in a direction away from the first folding mechanism 410.

[0176] For example, the third thickness B1 and the fourth thickness B2 can satisfy: B1>B2. In this way, the thickness of the end of the second body 200 close to the first folding mechanism 410 is larger, the width of the first folding mechanism 410 can not need to be reduced, the reliability of the first folding mechanism 410 is higher, and the reliability of the electronic device 1000 is higher.

[0177] Exemplarily, the third thickness B1 and the fourth thickness B2 can satisfy: B1-B2≥0.15mm, for example, B1-B2 can be equal to 0.15mm, 0.2mm, 0.3mm, 0.5mm, 1mm or 2mm, etc.

[0178] In an embodiment, the difference between the third thickness B1 and the fourth thickness B2 can also be greater than or equal to other values. In other embodiments, the difference between the third thickness B1 and the fourth thickness B2 can also satisfy other ranges. The specific application is not limited.

[0179] As shown in FIG. 3, exemplarily, the thickness of the end of the third body 300 away from the second folding mechanism 420 is defined as a fifth thickness C1. Wherein, the fifth thickness C1 can be the distance between the third upper surface 31 and the third lower surface 32 along the second direction at the end of the third body 300 away from the second folding mechanism 420, that is, the fifth thickness C1 can also be the distance between the surface of the fifth display area 915 of the first display screen 910 away from the third housing 800 and the surface of the third housing 800 away from the fifth display area 915 of the first display screen 910 along the second direction at the end of the third body 300 away from the second folding mechanism 420.

[0180] In other embodiments, the fifth thickness C1 can also adopt other definition methods. The specific application is not limited.

[0181] Exemplarily, the thickness of the end of the third body 300 close to the second folding mechanism 420 is defined as a sixth thickness C2. Wherein, the sixth thickness C2 can be the distance between the third upper surface 31 and the third lower surface 32 along the second direction at the end of the third body 300 close to the second folding mechanism 420, that is, the fifth thickness C1 can also be the distance between the surface of the fifth display area 915 of the first display screen 910 away from the third housing 800 and the surface of the third housing 800 away from the fifth display area 915 of the first display screen 910 along the second direction at the end of the third body 300 close to the second folding mechanism 420.

[0182] In other embodiments, the fifth thickness C1 can also adopt other definition methods. The specific application is not limited.

[0183] Exemplarily, the fifth thickness C1 and the sixth thickness C2 can satisfy: C1≠C2. Wherein, the fifth thickness C1 and the sixth thickness C2 are not equal due to non-processing assembly tolerance. In an embodiment, the thickness of the third body 300 can decrease in the direction away from the second folding mechanism 420.

[0184] Exemplarily, the fifth thickness C1 and the sixth thickness C2 can satisfy: C1 < C2. In this way, the thickness of the third body 300 near one end of the second folding mechanism 420 is larger, the width of the second folding mechanism 420 can not need to be reduced, the reliability of the second folding mechanism 420 is higher, and the reliability of the electronic device 1000 is higher.

[0185] Exemplarily, the fifth thickness C1 and the sixth thickness C2 can satisfy: C2-C1 ≥ 0.15mm, for example, C2-C1 can be equal to 0.15mm, 0.2mm, 0.3mm, 0.5mm, 1mm or 2mm, etc.

[0186] In an embodiment, the difference between the fifth thickness C1 and the sixth thickness C2 can also be greater than or equal to other numerical values. In other embodiments, the difference between the fifth thickness C1 and the sixth thickness C2 can also satisfy other ranges. Specifically, the present application is not limited.

[0187] Exemplarily, the first thickness A1 and the third thickness B1 can satisfy: |A1-B1| ≤ 1.5mm, for example, |A1-B1| can be equal to 0.1mm, 0.5mm, 0.78mm, 0.9mm, 1mm, 1.3mm or 1.5mm, etc.

[0188] It can be understood that by setting the absolute value of the difference between the first thickness A1 and the third thickness B1 in the range of less than or equal to 1.5mm, the difference between the thickness of one end of the first body 100 near the first folding mechanism 410 and the thickness of one end of the second body 200 near the first folding mechanism 410 is smaller, and the user's experience is better when the electronic device 1000 is in the unfolded state.

[0189] In an embodiment, the difference between the first thickness A1 and the third thickness B1 can also satisfy: |A1-B1| ≤ 2mm, for example, |A1-B1| can be equal to 0.1mm, 0.5mm, 0.78mm, 1mm, 1.3mm, 1.5mm or 2mm, etc.

[0190] In an embodiment, the difference between the first thickness A1 and the third thickness B1 can also satisfy: |A1-B1| ≤ 1mm, for example, |A1-B1| can be equal to 0.1mm, 0.3mm, 0.5mm, 0.78mm, 0.8mm or 1mm, etc.

[0191] In an embodiment, the difference between the first thickness A1 and the third thickness B1 can also satisfy: |A1-B1| ≤ 0.5mm, for example, |A1-B1| can be equal to 0.1mm, 0.2mm, 0.3mm, 0.38mm, 0.4mm or 0.5mm, etc.

[0192] In other embodiments, the absolute value of the difference between the first thickness A1 and the third thickness B1 can also satisfy other ranges. Specifically, the present application is not limited.

[0193] Exemplarily, the fourth thickness B2 and the sixth thickness C2 can satisfy: |B2-C2|≤1.5mm, for example, |B2-C2| can be equal to 0.1mm, 0.5mm, 0.78mm, 0.9mm, 1mm, 1.3mm or 1.5mm, etc.

[0194] It can be understood that by setting the absolute value of the difference between the fourth thickness B2 and the sixth thickness C2 to be less than or equal to 1.5mm, the difference between the thickness of the end of the second body 200 close to the second folding mechanism 420 and the thickness of the end of the third body 300 close to the second folding mechanism 420 is small, and the user's experience is good when the electronic device 1000 is in the unfolded state.

[0196] In an embodiment, the difference between the fourth thickness B2 and the sixth thickness C2 can also satisfy: |B2-C2|≤1mm, for example, |B2-C2| can be equal to 0.1mm, 0.3mm, 0.5mm, 0.78mm, 0.8mm or 1mm, etc.

[0197] In an embodiment, the difference between the fourth thickness B2 and the sixth thickness C2 can also satisfy: |B2-C2|≤0.5mm, for example, |B2-C2| can be equal to 0.1mm, 0.2mm, 0.3mm, 0.38mm, 0.4mm or 0.5mm, etc.

[0198] In other embodiments, the absolute value of the difference between the fourth thickness B2 and the sixth thickness C2 can also satisfy other ranges. Specifically, the present application is not limited.

[0199] The above describes the thickness reduction scheme of the electronic device 1000 in the first closed state in some embodiments in combination with related drawings. The following will specifically describe the related structures for realizing thickness reduction of the electronic device 1000 in some embodiments in combination with related drawings.

In this way, the structure for thinning the thickness of the first main body 100 is relatively simple and the process is relatively easy.

[0205] Exemplarily, the surface of the second display screen 920 away from the first housing 600 can be close to the first housing 600 along a direction away from the first folding mechanism 410.

[0211] It can be understood that, by arranging the second face 712 of the second middle frame 71 to be closer to the first face 711 of the second middle frame 71 along the direction away from the first folding mechanism 410, the thickness of the second housing 700 can decrease along the direction away from the first folding mechanism 410, so that the thickness of the second main body 200 can also decrease along the direction away from the first folding mechanism 410. In this way, the structure for thinning the thickness of the second main body 200 is relatively simple, and the process is relatively easy.

[0214] FIG. 13 is a partial cross-sectional view of an embodiment of the electronic device 1000 of FIG. 1 along line A-A.

[0215] Referring to FIG. 13, and in combination with FIG. 2, the third housing 800 can include a third middle frame 81 and a third back cover 82. The third back cover 82 of the third housing 800 can be located at one side of the third middle frame 81 of the third housing 800, and fixedly connected with the third middle frame 81 of the third housing 800.

[0216] Exemplarily, the third middle frame 81 can include a first face 811 and a second face 812 arranged oppositely.

The third back cover 82 can be fixedly connected with the second face 812 of the third middle frame 81. The surface of the third back cover 82 away from the third middle frame 81 can be the third lower surface 32 of the third main body 300 mentioned above.

[0217] Exemplarily, the thickness of the third housing 800 can decrease along the direction away from the second folding mechanism 420. In an embodiment, the second face 812 of the third middle frame 81 can be close to the first face 811 of the third middle frame 81 along the direction away from the second folding mechanism 420.

[0218] It can be understood that, by arranging the second face 812 of the third middle frame 81 to be close to the first face 811 of the third middle frame 81 along the direction away from the second folding mechanism 420, the thickness of the third housing 800 can decrease along the direction away from the second folding mechanism 420, so that the thickness of the third main body 300 can also decrease along the direction away from the second folding mechanism 420. In this way, the structure for thinning the thickness of the third main body 300 is relatively simple, and the process is relatively easy.

[0219] Exemplarily, the third back cover 82 of the third housing 800 can be arranged to be inclined along the direction away from the second folding mechanism 420 and towards the third middle frame 81 of the third housing 800. In this way, the third lower surface 32 can be close to the third upper surface 31 along the direction away from the second folding mechanism 420. The third main body 300 can be substantially wedge-shaped.

[0220] Exemplarily, the third middle frame 81 and the third back cover 82 can enclose a third accommodation space 80a. The thickness 81a of the third accommodation space 80a can decrease along the direction away from the second folding mechanism 420. The thickness 81a of the third accommodation space 80a can be defined as the distance between the second face 812 of the third middle frame 81 and the surface of the third back cover 82 facing the third middle frame 81 along the second direction. In other embodiments, the thickness 81a of the third accommodation space 80a can also be defined in other ways. The specific embodiments are not limited herein.

[0221] Please refer to FIGS. 11-13, and in combination with FIG. 3, in the present embodiment, the thicknesses of the first housing 600, the second housing 700, and the third housing 800 are thinned, thereby realizing the thicknesses of the first body 100, the second body 200, and the third body 300 being thinned. When the electronic device 1000 is in the first closed state, the first body 100, the second body 200, and the third body 300 can cooperate with each other, and the thickness of the electronic device 1000 in the first closed state can be thinned, and the user's holding experience is better.

[0222] The above describes the structures related to the thickness reduction of the electronic device 1000 in some embodiments in combination with the related drawings. The following will specifically describe the related solutions of the electronic device 1000 in some embodiments in combination with the related drawings.

[0223] FIG. 14 is a partial cross-sectional schematic view of an embodiment of the electronic device 1000 shown in FIG. 1 at the B-B line. FIG. 15 is a partial cross-sectional schematic view of another embodiment of the electronic device 1000 shown in FIG. 1 at the B-B line.

[0224] Please refer to FIGS. 14 and 15, and in combination with FIG. 2, for example, the second middle frame 71 of the second housing 700 and the second back cover 72 of the second housing 700 can enclose a first accommodation space 73. The thickness 73a of the first accommodation space 73 can decrease in a direction away from the second folding mechanism 420. In an embodiment, the first accommodation space 73 can be substantially wedge-shaped. The thickness 73a of the first accommodation space 73 can be defined as the distance between the surface of the second middle frame 71 facing the second back cover 72 and the surface of the second back cover 72 facing the second middle frame 71 in the second direction. In other embodiments, the thickness 73a of the first accommodation space 73 can also have other definition manners. The specific embodiments are not limited herein.

[0225] For example, the second body 200 can further include a first battery 25. The first battery 25 can be located in the first accommodation space 73 and fixedly connected to the second middle frame 71 of the second housing 700.

[0226] Please refer to FIGS. 14 and 15, and in combination with FIG. 3, for example, the thickness 25a of the first battery 25 can decrease in a direction away from the first folding mechanism 410. The thickness 25a of the first battery 25 can be defined as the distance between the surface of the first battery 25 facing the second middle frame 71 and the surface of the first battery 25 facing the second back cover 72 in the second direction. In other embodiments, the thickness 25a of the first battery 25 can also have other definition manners. The specific embodiments are not limited herein.

[0227] It can be understood that the first battery 25 is located in the first accommodating space 73, and since the thickness 73a of the first accommodating space 73 and the thickness 25a of the first battery 25 can both decrease in a direction away from the first folding mechanism 410, the first battery 25 can fully utilize the space of the first accommodating space 73, and the space utilization inside the second body 200 is high.

[0228] As shown in FIGS. 14 and 15, the first battery 25 may, for example, include a first surface 251 disposed toward the second rear cover 72 of the second housing 700.

[0229] As shown in FIG. 14, at least a portion of the first surface 251 of the first battery 25 may, for example, be substantially stepped.

[0230] As shown in FIG. 15, at least a portion of the first surface 251 of the first battery 25 may, for example, be substantially wedge-shaped.

[0231] It can be understood that since at least a portion of the first surface 251 of the first battery 25 is stepped or wedge-shaped, the first battery 25 can fully utilize the space of the first accommodating space 73, and the space utilization inside the second body 200 is high. In this way, under the premise that the thickness of the electronic device 1000 in the first closed state is thinned, the capacity of the first battery 25 is not easily negatively affected, and thus the endurance of the electronic device 1000 is not easily affected.

[0232] The first battery 25 may, for example, be a laminated battery. In this way, different shapes of the first surface 251 of the first battery 25 can be achieved by changing the shape of the laminations.

[0233] In other embodiments, the first surface 251 of the first battery 25 can also be other shapes. The specific embodiments are not limited herein.

[0234] It can be understood that the interior of the first body 100 and the interior of the third body 300 can each be provided with a battery (not shown) similar to the first battery 25 of the second body 200. The specific solutions can be referred to the related solutions of the first battery 25 of the second body 200, and will not be repeated here.

[0235] FIG. 16 is a partial cross-sectional schematic view of an embodiment of the electronic device 1000 shown in FIG. 1 at the C-C line.

[0236] As shown in FIG. 16, the second body 200 can further include a second battery 26 and a structural member 27.

[0237] The second battery 26 may, for example, be located in the first accommodating space 73 and fixedly connected to the second middle frame 71 of the second housing 700.

[0238] Referring to FIG. 16, and in combination with FIG. 3, the second battery 26 can be surrounded by the second rear cover 72 of the second housing 700 to form a second accommodation space 74. The thickness 74a of the second accommodation space 74 can decrease in a direction away from the first folding mechanism 410. At least a portion of the structural member 27 can be located in the second accommodation space 74. In an embodiment, the second accommodation space 74 can be substantially wedge-shaped. In this case, the thickness 74a of the second accommodation space 74 can be defined as a distance between a surface of the second battery 26 facing the second rear cover 72 and a surface of the second rear cover 72 facing the second battery 26 in the second direction. In other embodiments, the thickness 74a of the second accommodation space 74 can also be defined in other manners. The specific manners are not limited herein.

[0239] It can be understood that the second battery 26 can be located inside the second main body 200, and the structural member 27 can be arranged in the second accommodation space 74, so that the space utilization inside the second main body 200 is high. In addition, the embodiment can not need to reduce the thickness of the second battery 26 to make room for accommodating the structural member 27, so that the capacity of the second battery 26 is not easily reduced, and the endurance of the electronic device 1000 is not easily reduced.

[0240] As shown in FIG. 16, the structural member 27 can be a cross-board circuit board 271.

[0241] The second main body 200 can further include a first circuit board 281 and a second circuit board 282. The first circuit board 281 and the second circuit board 282 can be located in the second accommodation space 74 and on both sides of the second battery 26. The first circuit board 281 and the second circuit board 282 can be fixedly connected with the second middle frame 71. In this case, one of the first circuit board 281 and the second circuit board 282 can be a main board of the electronic device 1000, and the other one can be a sub-board of the electronic device 1000. The specific manners are not limited herein.

[0242] It can be understood that the positions of the first circuit board 281 and the second circuit board 282 can not be limited by FIG. 16.

[0243] The cross-board circuit board 271 can be connected with and electrically connected to the first circuit board 281 and the second circuit board 282. In an embodiment, the cross-board circuit board 271 can be electrically connected to the first circuit board 281 and the second circuit board 282 by wires (not shown in the figure). In other embodiments, the cross-board circuit board 271 can also be electrically connected to the first circuit board 281 and the second circuit board 282 by other manners. The specific manners are not limited herein.

[0244] It can be understood that the cross-board circuit board 271 can make full use of the space of the second accommodating space 74, and the space utilization inside the second main body 200 is high. Therefore, the second battery 26 can not need to reduce the thickness to make room for accommodating the cross-board circuit board 271, and the capacity of the second battery 26 is not easily reduced, so that the endurance of the electronic device 1000 is not easily reduced.

[0245] In an embodiment, the cross-board circuit board 271 can be located between the second battery 26 and the second middle frame 71 of the second housing 700. The cross-board circuit board 271 can be fixedly connected with the second battery 26 or the second back cover 72 of the second housing 700. The second battery 26 is fixedly connected with the second middle frame 71 of the second housing 700 through the cross-board circuit board 271. In this way, the distance between the second battery 26 and the second middle frame 71 of the second housing 700 is large, and the distance between the second battery 26 and the second back cover 72 of the second housing 700 is small. In this way, the second battery 26 needs to reduce the thickness to make room for accommodating the cross-board circuit board 271, and the capacity of the second battery 26 is reduced with the reduction of the thickness, so that the endurance of the electronic device 1000 is reduced.

[0246] It can be understood that compared with the embodiment in which the cross-board circuit board 271 is located between the second battery 26 and the second middle frame, in the embodiment, since the cross-board circuit board 271 is located between the second battery 26 and the second back cover 72 of the second housing 700, the distance between the second battery 26 and the second middle frame is small, and the distance between the second battery 26 and the second back cover 72 of the second housing 700 is large. In other words, there is a large space between the second battery 26 and the second back cover 72 of the second housing 700, and the second battery 26 can not need to reduce the thickness to make room for accommodating the cross-board circuit board 271, and the capacity of the second battery 26 can not be negatively affected. Therefore, under the premise of reducing the thickness of the electronic device 1000 in the first closed state, the capacity of the second battery 26 and the endurance of the electronic device 1000 are not easily affected. Therefore, the scheme of the embodiment can not only achieve the thinning of the thickness of the electronic device 1000 in the first closed state, but also not easily reduce the endurance of the electronic device 1000. In other words, the electronic device 1000 of the embodiment can balance the thin thickness and the good endurance.

[0247] It can be understood that the inside of the first main body 100 and the inside of the third main body 300 can be provided with a battery similar to the second battery 26 of the second main body 200 and a cross-board circuit board 271 (not shown in the figure) similar to the cross-board circuit board 271 of the second main body 200. The specific scheme can refer to the related scheme of the second battery 26 and the cross-board circuit board 271 of the second main body 200, which will not be repeated here.

[0248] FIG. 17 is a partial cross-sectional schematic view of another embodiment of the electronic device 1000 shown in FIG. 1 at line C-C.

[0249] As shown in FIG. 17, the structural member 27 can also be a wireless charging circuit board 272, for example. The wireless charging circuit board 272 can be located in the second accommodating space 74, and the wireless charging circuit board 272 can be fixedly connected with the second rear cover 72.

[0250] Referring to FIG. 17, and in combination with FIG. 3, the thickness 272a of the wireless charging circuit board 272 can decrease in a direction away from the first folding mechanism 410, for example. In an embodiment, the cross section of the wireless charging circuit board 272 can be substantially wedge-shaped. The thickness 272a of the wireless charging circuit board 272 can be defined as the distance between the surface of the wireless charging circuit board 272 facing the second battery 26 and the surface of the wireless charging circuit board 272 facing the second rear cover 72 in the second direction, for example. In other embodiments, the thickness 272a of the wireless charging circuit board 272 can also be defined in other manners. The specific embodiments are not limited in this regard.

[0251] It can be understood that the wireless charging circuit board 272 can make full use of the space of the second accommodating space 74, and the space utilization inside the second main body 200 is higher. Therefore, the embodiment can not need to reduce the thickness of the second battery 26 to create space to accommodate the wireless charging circuit board 272, and the capacity of the second battery 26 is not easily reduced, so as not to easily affect the endurance of the electronic device 1000.

[0252] In other embodiments, the wireless charging circuit board 272 can also be fixedly connected with the second battery 26. The shape of the wireless charging circuit board 272 can not be limited to the stepped shape shown in FIG. 17, for example. The cross section of the wireless charging circuit board 272 can be substantially wedge-shaped, for example. The specific embodiments are not limited in this regard.

[0253] As shown in FIG. 17, the second main body 200 can also include a third circuit board 283, for example. The third circuit board 283 can be located on the side of the second battery 26 away from the second rear cover 72 of the second housing 700, and the third circuit board 283 can be fixedly connected with the second battery 26.

[0254] It can be understood that the third circuit board 283 can not need to occupy the space of the second accommodating space 74, and the embodiment can not need to reduce the thickness of the wireless charging circuit board 272 to create space to accommodate the third circuit board 283, and the charging efficiency of the wireless charging circuit board 272 can not be easily reduced.

[0255] Exemplarily, the third circuit board 283 can be a main board of the electronic device 1000. In other embodiments, the third circuit board 283 can also be a sub-board of the electronic device 1000. The specific application is not limited.

[0256] As shown in FIG. 17, exemplarily, the second body 200 can further include a first vapor chamber 29. The first vapor chamber 29 can be located on a side of the second battery 26 away from the second rear cover 72 of the second housing 700, and fixedly connected with the second battery 26.

[0257] Exemplarily, a surface of the first vapor chamber 29 facing the second battery 26 is provided with a recess 291, and at least part of the third circuit board 283 can be located in the recess 291 of the first vapor chamber 29.

[0258] It can be understood that by arranging the third circuit board 283 in the recess 291 of the first vapor chamber 29, the space along the second direction of the second body 200 can be fully utilized, and the space utilization rate inside the second body 200 can be improved. Therefore, the present embodiment can not need to release space by reducing the thickness of the second battery 26 to accommodate the third circuit board 283, and the capacity of the second battery 26 can not be easily reduced, so as not to easily affect the endurance of the electronic device 1000.

[0259] In an embodiment, along a direction away from the first folding mechanism 410, the thickness of the second body 200 can remain substantially unchanged, and the thickness 272a of the wireless charging circuit board 272 can also remain substantially unchanged. The third circuit board 283 can be located between the wireless charging circuit board 272 and the second battery 26. The first vapor chamber 29 can be located on a side of the second battery 26 away from the wireless charging circuit board 272 and the third circuit board 283. In this way, the space utilization rate of the second body 200 along the second direction is low.

[0260] It can be understood that compared with the former embodiment, in the present embodiment, by arranging the third circuit board 283 and the wireless charging circuit board 272 on two sides of the second battery 26 respectively, and arranging the third circuit board 283 in the recess 291 of the first vapor chamber 29, the space utilization rate of the second body 200 along the second direction is high. In addition, under the premise of thinning the thickness of the electronic device 1000 in the first closed state, the third circuit board 283 can not need to occupy additional space along the second direction, and the present embodiment can not need to release space by reducing the thickness of the second battery 26 to accommodate the third circuit board 283, and the capacity of the second battery 26 can not be easily reduced. Therefore, the scheme of the present embodiment can not only achieve the thinning of the thickness of the electronic device 1000 in the first closed state, but also can not easily reduce the wireless charging performance and endurance of the electronic device 1000.

[0261] FIG. 18 is a partial cross-sectional schematic view of still another embodiment of the electronic device 1000 shown in FIG. 1 at line C-C.

[0262] As shown in FIG. 18, the structural member 27 can also be a second vapor chamber 273, for example. The second vapor chamber 273 can be located in the second accommodating space 74, and the second vapor chamber 273 can be fixedly connected with the second battery 26.

[0263] Referring to FIG. 18, and in combination with FIG. 3, the thickness 273a of the second vapor chamber 273 can decrease in a direction away from the first folding mechanism 410, for example. In an embodiment, the cross section of the second vapor chamber 273 can be substantially wedge-shaped. Here, the thickness 273a of the second vapor chamber 273 can be defined as the distance in the second direction between the surface of the second vapor chamber 273 facing the second battery 26 and the surface of the second vapor chamber 273 facing the second back cover 72. In other embodiments, the thickness 273a of the second vapor chamber 273 can also be defined in other manners. The specific manners are not limited in the present application.

[0264] It can be understood that the second vapor chamber 273 can make full use of the space of the second accommodating space 74, and the space utilization rate inside the second body 200 is higher. Therefore, the present embodiment can not need to reduce the thickness of the second battery 26 to create space to accommodate the second vapor chamber 273, and the capacity of the second battery 26 is not easily reduced, so that the endurance of the electronic device 1000 is not easily reduced.

[0265] In an embodiment, the thickness of the second body 200 can be substantially unchanged, and the thickness 273a of the second vapor chamber 273 can also be substantially unchanged. In this way, the electronic device 1000 cannot achieve the thinning of the thickness.

[0266] It can be understood that, compared with the previous embodiment, in the present embodiment, the second vapor chamber 273 can make full use of the space of the second accommodating space 74 under the premise that the thickness of the electronic device 1000 in the first closed state is thinned, and the heat dissipation efficiency of the second vapor chamber 273 is not easily significantly reduced. Therefore, the scheme of the present embodiment can not only achieve the thinning of the electronic device 1000 in the first closed state, but also can not easily reduce the heat dissipation performance of the electronic device 1000. In other words, the electronic device 1000 of the present embodiment can balance the thinner thickness and the better heat dissipation performance.

[0267] It can be understood that the interiors of the first body 100 and the third body 300 can each be provided with a vapor chamber similar to the second vapor chamber 273 of the second body 200 (not shown in the figure), and the specific schemes can refer to the related schemes of the second vapor chamber 273 of the second body 200, which will not be repeated here.

[0268] FIG. 19 is a partial cross-sectional schematic view of an embodiment of the electronic device 1000 shown in FIG. 10, taken along the line D-D.

[0269] As shown in FIG. 19, the second display screen 920 can include, for example, a cover plate 921, a display panel 922, and a support 923, which are arranged in a stack along the second direction. It can be understood that FIG. 19 and the following related drawings only schematically show some components included in the second display screen 920, and the actual shape, actual size, actual position, and actual structure of these components are not limited by FIG. 19 and the following drawings. In addition, the second display screen 920 can further include more or less structures. For example, when the second display screen 920 includes more structures, the second display screen 920 can further include a polarizer (not shown).

[0270] The cover plate 921 can be made of a colorless and transparent material, for example. The cover plate 921 can prevent the display panel 922 from being scratched and can protect the display panel 922.

[0271] The display panel 922 can be used to display images and can also have a touch function, for example. The display panel 922 can be a flexible display panel. For example, the display panel 922 can be an organic light-emitting diode (OLED) display panel, an active-matrix organic light-emitting diode (AMOLED) display panel, a mini organic light-emitting diode display panel, a micro organic light-emitting diode display panel, or a quantum dot light emitting diode (QLED) display panel, etc.

[0272] The support 923 can provide support for the display panel 922, for example. The support 923 can make the display panel 922 more flat.

[0273] The cover plate 921 and the support 923 can be respectively located on two sides of the display panel 922 and fixedly connected to the display panel 922, for example.

[0274] As shown in FIG. 19, the second display screen 920 can be fixedly connected with the first housing 600, for example. In an embodiment, the support 923 can be fixedly connected with the first housing 600, and the surface of the cover plate 921 away from the first housing 600 can constitute the first lower surface 12 of the first main body 100.

[0275] The first main body 100 can further include a first connecting member 13, for example. In an embodiment, the first connecting member 13 can be a heat-curing adhesive or a UV-curing adhesive. The heat-curing adhesive can be an adhesive that is cured by heating. The UV-curing adhesive can be an adhesive that can be rapidly cured under ultraviolet (UV) irradiation.

[0276] In other embodiments, the first connecting member 13 can also be other materials. The specific embodiments are not limited herein.

[0277] The first connecting member 13 can be formed at the edge of the second display screen 920 by a low injection pressure overmolding (LIPO) process, for example. The low injection pressure overmolding process is an injection molding process that uses lower injection pressure to coat plastic materials on another material or component to achieve specific design and functional requirements. In other embodiments, the first connecting member 13 can also be formed at the edge of the second display screen 920 by other processes.

[0278] As shown in FIG. 11, the first connecting member 13 can be located in the larger area of the first receiving space 60a, in other words, the first connecting member 13 can be located at the side of the second display screen 920 close to the first folding mechanism 410, for example.

[0279] The first main body 100 can further include a second connecting member 14, for example.

[0280] The second connecting member can be a pressure-sensitive adhesive, for example. The pressure-sensitive adhesive can be an adhesive that can be bonded to an adhesive object by applying pressure.

[0281] In other embodiments, the second connecting member 14 can also be other materials. The specific embodiments are not limited herein.

[0282] The second display screen 920 can be fixedly connected with the first housing 600 through the first connecting member 13 and the second connecting member 14 in sequence, for example.

[0283] In an embodiment, the first housing 600 needs to be provided with a step (not shown in the figure), and the second display screen 920 is fixedly connected with the step of the first housing 600 through the second connecting member 14, so as to realize the fixed connection between the second display screen 920 and the first housing 600. In this way, when the second display screen 920 displays an image, the black border of the second display screen 920 is wider, the display area of the second display screen 920 is smaller, and the visual experience of the user is poorer.

[0284] It can be understood that, compared with the embodiment in which the step needs to be provided to realize the fixed connection between the second display screen 920 and the first housing 600, the scheme of realizing the fixed connection between the second display screen 920 and the first housing 600 by providing the first connecting member 13 and the second connecting member 14 in the embodiment does not need to provide the step. In this way, when the second display screen 920 displays an image, the black border of the second display screen 920 is narrower, the display area of the second display screen 920 is larger, and the use experience of the user is better. Since the first connecting member 13 needs to occupy the space in the thickness direction of the first housing 600, the thickness of the first connecting member 13 is larger, and the embodiment can realize the space utilization of the first housing 600 by arranging the first connecting member 13 in the area with a larger thickness 61a (see FIG. 11) of the first accommodating space 60a.

[0285] It can be understood that the first connecting member 13 can be firmly bonded with the second display screen 920 and the second connecting member 14, and the cooperation between the first connecting member 13 and the second connecting member 14 can ensure that the second display screen 920 is not easily displaced or detached, which is beneficial to maintaining the stability of the second display screen 920.

[0286] It can be understood that the second connecting member 14 can be firmly bonded with the second display screen 920, the first middle frame 61, and the first connecting member 13, and the cooperation between the first connecting member 13 and the second connecting member 14 can ensure that the second display screen 920 is not easily displaced or detached, which is beneficial to maintaining the stability of the second display screen 920.

[0289] The fourth circuit board 284 can be located in the first accommodating space 73 and fixedly connected with the second middle frame 71 of the second housing 700.

[0290] Referring to FIG. 20, and in combination with FIG. 3, the fourth circuit board 284 can be surrounded by the second rear cover 72 of the second housing 700 to form a third accommodation space 75. The thickness of the third accommodation space 75 can decrease in a direction away from the first folding mechanism 410.

[0291] The heightening plate 285 can be located in the third accommodation space 75 and fixedly connected to the fourth circuit board 284. In an embodiment, the heightening plate 285 can be located on a side of the fourth circuit board 284, which is close to the first folding mechanism 410 and faces the second rear cover 72.

[0292] It can be understood that the heightening plate 285 can make full use of the space of the third accommodation space 75, and the space utilization rate of the second main body 200 can be improved.

[0293] FIG. 21 is a partial cross-sectional view of another embodiment of the electronic device 1000 shown in FIG. 1 at the E-E line.

[0294] As shown in FIG. 21, the second main body can further include a fourth circuit board 284 and a device 293. The fourth circuit board 284 can be a main board of the electronic device 1000. In other embodiments, the fourth circuit board 284 can also be a sub-board of the electronic device 1000.

[0295] The fourth circuit board 284 can be located in the first accommodation space 73 and fixedly connected to the second middle frame 71 of the second housing 700.

[0296] Referring to FIG. 21, and in combination with FIG. 3, the fourth circuit board 284 can be surrounded by the second rear cover 72 of the second housing 700 to form a third accommodation space 75. The thickness of the third accommodation space 75 can decrease in a direction away from the first folding mechanism 410.

[0298] It can be understood that the device 293 can make full use of the space of the third accommodation space 75, and the space utilization rate of the second main body 200 can be improved.

In an embodiment, the first surface 621 of the first back cover 62 can be closer to the first middle frame 61 in a direction away from the first folding mechanism 410. Wherein, the thickness 62a of the first back cover 62 can be defined as the distance between the first surface 621 of the first back cover 62 and the surface of the first back cover 62 facing the first middle frame 621 in the second direction. In other embodiments, the thickness 62a of the first back cover 62 can also be defined in other ways. The specific application is not limited.

[0303] It can be understood that by setting the first surface 621 of the first back cover 62 to be closer to the first middle frame 61 in a direction away from the first folding mechanism 410, the thickness of the first back cover 62 can decrease in a direction away from the first folding mechanism 410, so that the thickness of the first housing 600 can decrease in a direction away from the first folding mechanism 410, thereby the thickness of the first main body 100 can decrease in a direction away from the first folding mechanism 410. In this way, the structure of the thickness reduction of the first main body 100 is also relatively simple, and the process is relatively easy.

[0304] Exemplarily, the thickness 61a of the first receiving space 60a can remain substantially unchanged in a direction away from the first folding mechanism 410.

In an embodiment, the first surface 721 of the second back cover 72 can be closer to the second middle frame 71 along a direction away from the first folding mechanism 410. Wherein, the thickness 72a of the second back cover 72 can be defined as a distance between the first surface 721 of the second back cover 72 and a surface of the second back cover 72 facing the second middle frame 71 along the second direction. In other embodiments, the thickness 72a of the second back cover 72 can also be defined in other manners. The specific application does not make any limitation.

[0308] It can be understood that by setting the first surface 721 of the second back cover 72 closer to the second middle frame 71 along a direction away from the first folding mechanism 410, the thickness of the second back cover 72 of the second shell 700 can decrease along a direction away from the first folding mechanism 410, so that the thickness of the second main body 200 can also decrease along a direction away from the first folding mechanism 410. In this way, the structure for realizing the thickness reduction of the second main body 200 is also relatively simple, and the process is also relatively easy.

In an embodiment, the first surface 821 of the third back cover 82 can be closer to the third middle frame 81 along a direction away from the second folding mechanism 420.

[0313] It can be understood that by setting the first surface 821 of the third back cover 82 closer to the third middle frame 81 along a direction away from the second folding mechanism 420, the thickness of the third back cover 82 of the third shell 800 can decrease along a direction away from the second folding mechanism 420, so that the thickness of the third main body 300 can also decrease along a direction away from the second folding mechanism 420. In this way, the structure for realizing the thickness reduction of the third main body 300 is also relatively simple, and the process is also relatively easy.

[0314] Exemplarily, the thickness 81a of the third receiving space 80a can remain substantially unchanged along a direction away from the second folding mechanism 420.
