[0047] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the utility model. Instead, they are only examples of devices and methods consistent with some aspects of the utility model as detailed in the attached claims.

[0048] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate directions or positional relationships based on the attached Figure 1The orientation or positional relationship shown is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0049] Unless otherwise defined, all technical terms used in the embodiments of the present invention have the same meanings as commonly understood by those skilled in the art.

[0050] In the related art, taking a folding mobile phone as an example, the whole is divided into two parts: the base side and the folding side. The main heat-generating devices in the design are usually arranged on the base side. Because there are a lot of gaps in the structure of the rotating shaft, the heat is blocked from transferring from the base side to the folding side. At the same time, the thermal conductivity of the screen itself is relatively low. Therefore, the heat mainly relies on the diffusion of the base side itself, so the heat dissipation efficiency is poor, resulting in the body temperature of the base side being generally higher than that of the folding side. In the related art, the use of bendable graphite technology to transfer the heat from the base side to the folding side through the rotating shaft appears, but the use of bendable graphite will make the whole machine thicker, which is not conducive to the thin and light design of the whole machine.

[0051] Therefore, the utility model provides a foldable electronic device, which can realize heat transfer between two body modules without adding additional heat dissipation structure, improve the heat dissipation efficiency of the base side, and facilitate the light and thin design of the whole machine.

[0052] The utility model provides a foldable electronic device. Specifically, the foldable electronic device can be any of various types of computer system devices that are mobile or portable and perform wireless communication. Specifically, the electronic device can be a mobile phone or a smart phone (for example, a phone based on iPhone TM, a phone based on Android TM), a portable game device (for example, Nintendo DS TM, PlayStation Portable TM, Gameboy Advance TM, iPhone TM), a laptop computer, a PDA, a portable Internet device, a music player, and a data storage device, other handheld devices, and headsets, etc. The electronic device can also be other wearable devices that need to be charged (for example, head-mounted devices (HMD) such as electronic bracelets, electronic necklaces, electronic devices, or smart watches).

[0053] The electronic device can also be any one of a plurality of electronic devices, including but not limited to cellular phones, smart phones, other wireless communication devices, personal digital assistants, audio players, other media players, music recorders, video recorders, other media recorders, radios, medical devices, vehicle transportation instruments, calculators, programmable remote controls, pagers, laptop computers, desktop computers, printers, netbook computers, personal digital assistants (PDAs), portable multimedia players (PMPs), Moving Picture Experts Group (MPEG-1 or MPEGG-2) Audio Layer 3 (MP3) players, portable medical devices, and digital cameras and combinations thereof.

[0054] In some cases, the electronic device can perform multiple functions (e.g., play music, display video, store pictures, and receive and send phone calls). If desired, the electronic device can be a device such as a cellular phone, a media player, other handheld device, a wristwatch device, a pendant device, a handset device, or other compact portable device.

[0055] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0056] Combination Figure 1 and Figure 2 As shown, this embodiment provides a foldable electronic device, which includes: a first body module 1, a second body module 2, a hinge module 3 and a screen module 4.

[0057] The first body module 1 and the second body module 2 are rotatably connected via a rotating shaft module 3 .

[0061] In some possible implementations, reference Figure 1 As shown, the foldable electronic device also includes an unfolded state. In the unfolded state, the first body module 1 and the second body module 2 are flattened against each other, and the flexible screen 41 is laid flat, so that videos, pictures and other information can be displayed on a larger display surface 4101.

[0062] In some possible implementations, the flexible screen 41 includes an organic light-emitting diode (OLED) display.

[0063] In some possible implementations, the structure of the organic light emitting diode display screen has various forms.

[0064] Exemplarily, an organic light-emitting diode display screen includes a substrate, an organic light-emitting diode (OLED) layer, and a thin film encapsulation (TFE) layer which are stacked in sequence.

[0065] In another exemplary embodiment, the organic light-emitting diode display screen includes a substrate, a thin film transistor (TFT) layer, an organic light-emitting diode (OLED) layer, a thin film encapsulation (TFE) layer, a touch layer and a polarizer which are stacked in sequence.

[0066] It should be noted that the layer structure of the organic light emitting diode display screen is not limited to the two structural forms listed above. Under the condition of meeting the requirements of folding display, the organic light emitting diode display screen can also adopt other layer structure forms.

[0067] In some embodiments, the screen pressing member 42 is located at the edge of the first body module 1. In the folded state, the screen pressing member 42 on the first body module 1 abuts against the second body module 2. Through the above arrangement, the first body module 1 and the second body module 2 can transfer heat using the screen pressing member 42 on the first body module 1.

[0068] In some embodiments, the screen pressing member 42 is located at the edge of the second body module 2. In the folded state, the screen pressing member 42 on the second body module 2 abuts against the first body module 1. Through the above arrangement, the first body module 1 and the second body module 2 can use the screen pressing member 42 on the second body module 2 for heat transfer.

[0069] Combination Figure 2 As shown, in some embodiments, the number of screen pressing components 42 is at least two, and at least one screen pressing component 42 is respectively provided on the edge of the first fuselage module 1 and the edge of the second fuselage module 2; in the folded state, the screen pressing component 42 located on the first fuselage module 1 abuts against the screen pressing component 42 located on the second fuselage module 2.

[0070] Through the above arrangement, in the folded state, the screen pressing member 42 on the first body module 1 and the screen pressing member 42 on the second body module 2 are in abutment with each other, and the first body module 1 and the second body module 2 can transfer heat by using the two screen pressing members 42 .

[0071] Exemplarily, the screen pressing member 42 includes a first screen pressing member 423 and a second screen pressing member 424. The first screen pressing member 423 is located on the first fuselage module 1, and the second screen pressing member 424 is located on the second fuselage module 2. In the folded state, the first screen pressing member 423 and the second screen pressing member 424 are in head-to-head upper and lower abutment contact.

[0072] Combination Figure 3 and Figure 4 As shown, in some embodiments, the screen pressing member 42 includes a base structure 421 and a filler structure 422; the filler structure 422 is located in the base structure 421. In order to improve the thermal conductivity of the screen pressing member 42, the screen pressing member 42 of this embodiment is provided with the filler structure 422 in the base structure 421, so that the thermal conductivity of the screen pressing member 42 can be improved by utilizing the composite properties of the base structure 421 and the filler structure 422.

[0073] Combination Figure 3 and Figure 4 As shown, in some embodiments, the thermal conductivity of the filler structure 422 is greater than the thermal conductivity of the base structure 421. By doping the base structure 421 with a filler structure 422 having a larger thermal conductivity, the overall thermal conductivity efficiency of the screen pressing member 42 can be improved without destroying the base structure 421.

[0074] Combination Figure 3 and Figure 4 As shown, in some embodiments, the base structure 421 includes a connecting portion 4211 and a screen pressing portion 4212, the connecting portion 4211 is used to connect the first body module 1 or the second body module 2, the screen pressing portion 4212 is connected to the connecting portion 4211 and extends to the display surface 4101 of the flexible screen 41, and the screen pressing portion 4212 is used to apply pressure to the flexible screen 41 toward the first body module 1 or the second body module 2.

[0075] In this embodiment, the base structure 421 is connected to the first body module 1 or the second body module 2 through the connecting part 4211. The connecting part 4211 can provide a heat conduction channel between the screen pressing part 42 and the body module. The screen pressing part 4212 is used to press the flexible screen 41 to play a screen pressing role.

[0076] In some possible implementations, the base structure 421 is made of plastic materials, including but not limited to polyamide (also known as nylon), polycarbonate (PC), fiber glass (FG), polyethylene (PE), polyether, polyethylene glycol terephthalate (PET), polymethyl methacrylate (PMMA), polypropylene, polystyrene (PS), polyvinyl chloride (PVC), etc. Any one of the above materials or any combination of several materials can be used to form this embodiment.

[0077] In some other possible implementations, the filler structure 422 is made of metal oxides, non-metallic compounds, carbon-based materials, etc. Among them, metal oxides, such as aluminum oxide, magnesium oxide, etc.; non-metallic compounds, such as silicon carbide, boron nitride, etc.; carbon-based materials, such as carbon fiber, carbon nanotubes, graphene, etc. The screen pressing member 42 filled with these materials can not only meet the mechanical properties but also have higher thermal conductivity, and can more easily transfer heat from the high-temperature body module to the low-temperature body module when the foldable electronic device is used in a closed state.

[0078] Figure 3 and Figure 4 This is a combination of two filler structures 422 and a matrix structure 421 provided in this embodiment. Figure 3 As shown, the filler structure 422 is a continuous structure, which is arranged throughout the entire base structure 421. The screen pressing member 42 can use the filler structure 422 to quickly pass through the base structure 421 to transfer heat. Figure 4 As shown, the filler structure 422 is a dispersed structure, which is dispersed in the base structure 421, so that the thermal conductivity of the entire base structure 421 can be improved, thereby facilitating rapid heat transfer.

[0079] Need to explain, Figure 3 and Figure 4 These are just two examples based on the inventive concept of the present utility model, but the implementation methods of the inventive concept of the present utility model are far more than the above two. The present utility model cannot list them one by one, but it should be considered that any implementation method based on the same inventive concept belongs to the protection scope of the present utility model.

[0080] Combination Figure 5 and Figure 6 As shown, in some embodiments, the screen module 4 also includes a first thermally conductive connector 43, which is located between the screen pressing part 4212 and the display surface 4101 of the flexible screen 41, and the first thermally conductive connector 43 is used to connect the screen pressing part 4212 to the display surface 4101 of the flexible screen 41.

[0081] Through the above arrangement, the flexible screen 41 and the screen pressing part 4212 are thermally connected via the first thermally conductive connecting member 43, and the heat transfer efficiency between the two is higher.

[0082] Exemplarily, the first thermally conductive connecting member 43 includes a highly thermally conductive double-sided adhesive or thermally conductive silicone.

[0083] Therefore, after improving the thermal conductivity of the screen pressing member 42 itself, this embodiment can reduce the heat transfer resistance between the screen and the screen pressing member 42 by arranging high thermal conductivity double-sided tape between the screen pressing member 42 and the flexible screen 41.

[0084] Combination Figure 5 and Figure 6 As shown, in some embodiments, the foldable electronic device also includes a heat dissipation layer 5, which is located on the non-display surface 4102 of the flexible screen 41, and is located between the non-display surface 4102 and the first body module 1, and / or is located between the non-display surface 4102 and the second body module 2.

[0085] By arranging the heat dissipation layer 5 between the non-display layer of the flexible screen 41 and the body module, the heat of the body module can be evenly dispersed along the non-display layer of the flexible screen 41, thereby improving the heat dissipation efficiency of the body module.

[0086] Exemplarily, the heat dissipation layer 5 has a directional heat conduction capability, and can conduct the heat of the body module toward the location of the screen pressing member 42 , thereby allowing more heat to be transferred toward the low-temperature body module through the screen pressing member 42 .

[0087] In some embodiments, the heat dissipation layer 5 includes at least one of a graphite layer, a heat spreader, a metal heat dissipation plate, and a thermally conductive silicone layer. Any of the above heat dissipation layers 5 can be used to improve the heat dissipation efficiency of the body module.

[0088] Combination Figure 1 and Figure 2 As shown, in some embodiments, at least a portion of the protrusion of the screen pressing member 42 presses the edge of the flexible screen 41 onto the first body module 1 or the second body module 2. The screen pressing member 42 can be connected to the body module to press the edge of the flexible screen 41.

[0089] Combination Figure 5 and Figure 6 As shown, in some embodiments, the foldable electronic device also includes a heating device 6, which is located in one of the first body module 1 and the second body module 2, and the heating device 6 and the non-display surface 4102 of the flexible screen 41 are respectively arranged on the inner and outer sides of the shell of the first body module 1 or the second body module 2, and the heat of the heating device 6 can be transferred to the other of the first body module 1 and the second body module 2 through the flexible screen 41 and the screen pressing member 42.

[0090] Through the above arrangement, the screen pressing member 42 can be used to transfer the heat generated by the heating device 6 in a certain body module to another body module, thereby reducing the temperature of the body module where the heating device 6 is located and improving the heat dissipation efficiency of the entire machine.

[0091] In some possible implementations, the heating device 6 is connected to the inner side of the shell of the body module through the second heat-conducting connector 8, so that the heat generated by the heating device 6 can be transferred to the shell of the body module as quickly as possible, and then transferred to another body module through the flexible screen 41 and the screen pressing component 42.

[0092] Exemplarily, the second thermally conductive connecting member 8 includes a highly thermally conductive double-sided adhesive or thermally conductive silicone.

[0093] In another possible implementation, a circuit board 9 is further provided in the first body module 1 or the second body module 2, and the heating device 6 is located on the circuit board 9. Exemplarily, the circuit board 9 and the heating device 6 are part of a main board module.

[0094] In some possible implementations, the circuit board 9 includes a printed circuit board (PCB), a flexible printed circuit board (FPC), a rigid-flexible board, and the like.

[0095] Combination Figure 5 and Figure 6As shown, in some embodiments, the foldable electronic device further includes a battery module 7, and the battery module 7 is located in the other one of the first body module 1 and the second body module 2.

[0096] Through the above arrangement, the body module with the heating device 6 is the base side, generating a large amount of heat, and the body module with the battery module 7 is the folding side, generating a small amount of heat. Therefore, in the folded state, the heat of the base layer is transferred to the folding side by the screen pressing member 42, which can reduce the problem on the base side, and use the body surface of the folding side to dissipate heat outward, thereby improving the heat dissipation efficiency of the whole machine.

[0097] It should be pointed out that, in the present utility model, unless otherwise clearly stipulated and limited, the first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through another feature between them. Moreover, the first feature being "above", "above" and "above" the second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature includes the first feature being directly below and obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
