Description

Technical Field

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

[0002] With the development of science and technology, various electronic devices have become indispensable products in daily life and production. Among them, foldable electronic devices have gradually become a development trend due to their advantages of large display area and easy portability.

[0003] Since the display area of ​​foldable electronic devices is large, the volume of the housing supporting the display screen is large, and the corresponding weight is heavy. Therefore, how to reduce the weight of the housing and make the foldable electronic devices lighter has become an urgent problem to be solved. Summary of the invention

[0004] The present application provides a foldable electronic device, the shell of which is light in weight, thereby reducing the overall weight of the foldable electronic device.

[0005] The present application provides a foldable electronic device, comprising: a first shell, a second shell, a rotating mechanism and a display screen; the rotating mechanism is connected between the first shell and the second shell, and the display screen is installed on the first shell, the second shell and the rotating mechanism; when the rotating mechanism rotates, the first shell and the second shell rotate relative to each other to drive the display screen to fold or unfold; the first shell comprises a first middle frame, the first middle frame is made of a first metal, and the density of the first metal is less than the density of the aluminum alloy.

[0006] In the present application, the first middle frame is made of a first metal, and the density of the first metal is less than that of an aluminum alloy. Compared with the prior art in which the first middle frame is made of an aluminum alloy material, the weight of the first middle frame in this embodiment is reduced, so that the weight of the first shell is reduced, and finally the weight of the foldable electronic device is reduced.

[0007] In some embodiments, the first metal is any one of magnesium-aluminum alloy, magnesium alloy, magnesium-lithium alloy and aluminum-lithium alloy. As a result, the first middle frame is light in weight, and the weight of the first shell can be reduced. In addition, by using the above raw materials, the raw materials for preparing the first middle frame are easy to obtain and the cost is low.

[0008] In some embodiments, the first shell also includes a first frame, a first protective member and a first adhesive layer, the first frame is made of an insulating material, the first frame is fixed to the first middle frame, and the rotating mechanism is installed on the first frame; one side of the first adhesive layer is bonded to the first middle frame and the first frame, and the other side of the first adhesive layer is bonded to the display screen, so that the display screen, the first middle frame, the first frame and the first adhesive layer enclose a first closed area; the first protective member is made of an insulating material, and the first protective member is fixed to at least a portion of the surface of the first middle frame exposed outside the first closed area.

[0009] The first adhesive layer is specifically in a rectangular ring shape. The bottom of the first adhesive layer is bonded to the first middle frame and the first frame body, and the top of the first adhesive layer is bonded to the display screen. The first adhesive layer plays a sealing and fixing role. The first adhesive layer is specifically on the upper surface of the first middle frame. The upper surface of the first middle frame outside the outer edge of the first adhesive layer is in a bare state relative to the first adhesive layer. The upper surface of the first middle frame exposed relative to the first adhesive layer is easily corroded.

[0010] In this embodiment, the first protection portion is used to protect the portion of the first middle frame exposed relative to the first adhesive layer to prevent the portion of the first middle frame exposed relative to the first adhesive layer from being corroded.

[0011] In some embodiments, the first protective member includes a first sealing member, which includes a first sealing portion; a portion of the first adhesive layer is bonded between the first middle frame and the display screen; in the width direction of the foldable electronic device, there is a first gap between the first adhesive layer and the first frame body and the rotating mechanism; the portion of the first middle frame located in the first gap is a first avoidance area, and the first sealing portion is laminated and fixed to at least a portion of the first avoidance area.

[0012] The display screen includes a first display part, a third display part and a second display part connected in sequence, the first display part is installed on the first shell, and the second display part is installed on the second shell. The rotating mechanism is arranged opposite to the third display part, and the width of the third display part is larger than the rotating mechanism, that is, a part of the third display part extends to the left to be opposite to the first shell, and another part of the third display part extends to the right to be opposite to the second shell, so as to realize the bending of the display screen.

[0013] Since a portion of the third display portion extends to be opposite to the first shell, and another portion of the third display portion extends to be opposite to the second shell, the third display portion needs to be bent when the foldable electronic device is folded. Therefore, the third display portion cannot be bonded to the first shell and the second shell. The above-mentioned first avoidance area is used to avoid the portion of the third display portion opposite to the first middle frame so that the third display portion can be bent smoothly. Then, by providing a first sealing portion in the first avoidance area, the first avoidance area can be prevented from being corroded, that is, the first middle frame can be prevented from being corroded.

[0014] At least part of the rotating mechanism is made of the second metal, which may be stainless steel or titanium alloy, etc. Therefore, when the rotating mechanism and the first middle frame are placed in a salt spray environment such as seawater at the same time, and after the rotating mechanism and the first middle frame are electrically connected, the first middle frame will be rapidly corroded.

[0015] In the embodiment of the present application, the part where the rotating mechanism is connected to the first shell is supported by the first frame, and the rotating mechanism is not in direct contact with the first middle frame. Then, the first middle frame and the rotating mechanism are completely isolated from each other by the first sealing portion of the first sealing member. Even if the foldable electronic device falls into seawater, the first middle frame and the rotating mechanism will not be in contact with the seawater at the same time, thereby preventing the first middle frame from being electrically connected to the rotating mechanism and immersed in seawater at the same time, causing accelerated corrosion of the first middle frame.

[0016] In some embodiments, in the height direction of the foldable electronic device, the orthographic projection of the first adhesive layer on the first middle frame and the orthographic projection of the first sealing portion on the first middle frame are completely offset. Specifically, there is a gap between the edge of the first adhesive layer and the edge of the first sealing portion, or the edge of the first adhesive layer contacts the edge of the first sealing portion. In this way, the first sealing portion can be prevented from affecting the first adhesive layer, ensuring that the first adhesive layer can reliably bond to the first display portion of the display screen; and the first sealing portion can reliably seal the first avoidance area.

[0017] In some embodiments, in the thickness direction of the foldable electronic device, the first sealing portion completely covers the first avoidance area, thereby making all the first avoidance areas completely covered to protect the first avoidance areas.

[0018] In some embodiments, the first sealing portion further extends to be laminated and fixed between the first adhesive layer and the first middle frame. Thus, even if the width of the third display portion is narrow, that is, the width of the third display portion extending to the first middle frame is small, the first adhesive layer is close to the rotating mechanism, that is, the width of the first avoidance area is narrow, the first sealing portion can be provided to protect the first avoidance area.

[0019] In some embodiments, the first sealing portion further extends to be stacked on the first frame body. In this case, the first sealing portion can also seal the gap between the first frame body and the first avoidance area to better protect the first avoidance area.

[0020] In some embodiments, the first middle frame includes a first carrier and a first support plate; the first carrier and the first support plate are fixedly connected along the width direction of the electronic device; the first frame body includes a first isolation member; the first isolation member is stacked on the first carrier, and the first covering frame is covered on the outer periphery of the first support frame; the rotating mechanism is fixed to the first carrier; one side of the first adhesive layer is bonded to the first support plate and the first frame body, and the other side of the first adhesive layer is bonded to the display screen; there is a first interval between the first adhesive layer and the first isolation member, and the surface of the first support plate located between the first adhesive layer and the first isolation member forms a first avoidance area.

[0021] The first bearing member is used to support the first isolating member, and the first isolating member is used to support a part of the rotating mechanism and isolate the rotating mechanism from the first bearing member to prevent the first bearing member and the rotating mechanism from directly contacting each other. The upper surface of the first supporting plate is used to support the first display part of the display screen and to support a part of the third display part. The provision of the first supporting plate also facilitates the provision of the first adhesive to fix the first display part.

[0022] In some embodiments, the first middle frame also includes a first support frame, which is in the shape of a frame with an opening on one side, and is fixed to the outer periphery of the first support plate and the first carrier, and the first carrier is located at the opening of the first support frame; the first frame body also includes a first covering frame, which is in the shape of a frame with an opening on one side, and the first isolation member is fixed to the opening of the first covering frame; the first covering frame covers the outer periphery of the first support frame.

[0023] The first covering frame covers the first supporting frame to prevent the first middle frame from being exposed, thereby preventing the first middle frame from being corroded. In addition, the first covering frame is made of materials such as plastic parts, and the outer surface of the first covering frame is easier to process and is easier to color, thereby improving the aesthetics of the foldable electronic device.

[0024] In some embodiments, a first covering edge is provided on a side of the first isolating member facing the first covering frame, and a first wrapping edge is provided on a side of the first wrapping frame facing the first isolating member; the first covering edge and the first wrapping edge are both stacked on the edge of a surface of the first support plate facing the display screen; a portion of the first adhesive layer is bonded to the first wrapping edge and the surface of the first support plate facing the display screen, another portion of the first adhesive layer is bonded to the surface of the first support plate facing the display screen, and the first avoidance area is located between the first covering edge and another portion of the first adhesive layer. The first covering edge and the first wrapping edge serve to protect the first support plate, prevent the first support plate from being corroded, and prevent the first support plate and the rotating mechanism from being in a salt spray environment at the same time.

[0025] In some embodiments, a first elastic sheet is protruded from one side of the first supporting member toward the first isolating member, and the first elastic sheet passes through the first isolating member and abuts against the rotating mechanism; a first insulating member is provided between the first isolating member and the rotating mechanism, and the first insulating member surrounds the first elastic sheet and abuts against the rotating mechanism.

[0026] In general, the antenna of the foldable electronic device is installed inside the first shell, and the resonant circuit of the foldable electronic device is installed inside the second shell. After the first shell and the second shell are grounded, that is, after the first middle frame and the second middle frame are grounded, the antenna and the resonant circuit can be better tuned to improve the performance of the antenna. In the present application, by setting the first spring clip, the electrical connection between the first middle frame and the rotating mechanism is achieved, so as to facilitate the common ground design of the first shell and the second shell, thereby achieving the effect of improving the performance of the antenna. The first insulating member protects the first spring clip to prevent the first spring clip from being corroded. In addition, the first insulating member also protects the contact position between the first spring clip and the rotating mechanism to prevent the first spring clip and the rotating mechanism from being in a salt spray environment at the same time, which may accelerate the corrosion of the first spring clip.

[0027] In some embodiments, the first carrier includes a first carrier bottom plate and a first carrier side plate fixedly connected, and the first isolation member includes a first isolation bottom plate and a first isolation side plate fixedly connected; in the thickness direction of the foldable electronic device, the first isolation bottom plate is stacked on the first carrier bottom plate; in the width direction of the foldable electronic device, the first isolation side plate is stacked on the first carrier side plate; the first isolation bottom plate and the first isolation side plate enclose a first receiving groove, and a part of the rotating mechanism is installed in the first receiving groove; the first spring sheet is protruded from the first carrier bottom plate, and the first isolation member is fixed to the first isolation bottom plate; or, the first spring sheet is protruded from the first carrier side plate, and the first isolation member is fixed to the first isolation side plate.

[0028] When the foldable electronic device is in a folded state, the first isolation bottom plate constitutes a part of the appearance surface of the foldable electronic device.

[0030] The first connection boss is provided so that the rotating mechanism and the first middle frame can be fixedly connected through the first connection piece. The second sealing portion is provided to prevent the first connection boss from being corroded; in addition, the second sealing portion isolates the first connection boss from the rotating mechanism, and when the first middle frame and the rotating mechanism are electrically connected, it can also prevent the first connection boss and the rotating mechanism from being in a salt spray environment at the same time, which may cause the first connection boss to be corroded faster.

[0031] In some embodiments, the first middle frame is provided with a first connection hole, and the first connection hole passes through the first bearing base plate and the first connection boss along the thickness direction of the foldable electronic device; the first connector passes through the first connection hole and the second sealing portion to be fixed to the rotating mechanism; the first protective member also includes a second sealing member, and the second sealing member is made of an insulating material; the second sealing member is arranged between the hole wall surface of the first connection hole and the first connector. By providing the second sealing member, the hole wall surface of the first connection hole is prevented from being corroded; in addition, the second sealing member isolates the first connector from the hole wall surface of the first connection hole, and the second sealing member also completely isolates the hole wall surface of the first connection hole from the rotating mechanism. When the first middle frame and the rotating mechanism are electrically connected, it can also prevent the first connector and the rotating mechanism from being in a salt spray environment at the same time, which causes the hole wall surface of the first connection hole to be acceleratedly corroded.

[0032] In some embodiments, the first sealing member further comprises a first connecting portion, and the first sealing member and the second sealing member are respectively connected on both sides of the first connecting portion, and the first sealing member, the first connecting portion and the second sealing member are integrally formed. Thus, processing can be facilitated and processing efficiency can be improved. The first connecting portion is stacked between the first isolation side plate and the rotating mechanism. Thus, the first sealing member can well seal the parts that need to be sealed, and the structural compactness of the foldable electronic device can be improved.

[0033] In some embodiments, the first shell is provided with a first mounting hole, and the first mounting hole passes through the first support frame and the first covering frame in a direction perpendicular to the thickness of the foldable electronic device; the first middle frame also includes a first reinforcement portion, the first reinforcement portion is fixed to the side of the first support plate facing the display screen, and the first reinforcement portion is stacked on a portion of the first support frame where the first mounting hole is provided, and the first reinforcement portion faces the display screen; a portion of the first adhesive layer is bonded to the first reinforcement portion, and a second interval is provided between the first adhesive layer and the first covering frame, and a portion of the first reinforcement portion located at the second interval is a first exposed area; the first protective member also includes a third sealing member, and the third sealing member is stacked on at least part of the first exposed area.

[0034] The number of the first mounting holes may be multiple, and the multiple first mounting holes are respectively used to install components such as a volume button, a power button, a subscriber identity module (SIM) card tray, etc. Some of the first mounting holes are located on the left side of the first housing, and other first mounting holes may be located on the front side or the rear side of the first housing.

[0035] The first mounting hole located on the left side of the first shell is described in detail. The first reinforcement portion is fixed to the top of the left side portion of the first covering frame, and the upper surface of the first reinforcement portion is flush with the upper surface of the first support plate. A portion of the first adhesive layer is bonded to a portion of the upper surface of the first reinforcement portion. Another portion of the upper surface of the first reinforcement portion is distributed to the left and right of the first wrapping edge of the first covering frame, and another portion of the upper surface of the first reinforcement portion is located between the first wrapping edge and the first adhesive layer.

[0036] In the height direction of the foldable electronic device, the orthographic projection of a portion of the first adhesive layer on the first support plate is completely offset from the orthographic projection of the third sealant on the first support plate. Specifically, there is a gap between the left edge of a portion of the first adhesive layer and the right edge of the third sealant, or the left edge of a portion of the first adhesive layer is in contact with the right edge of the third sealant. In this way, the third sealant can be prevented from affecting the first adhesive layer, ensuring that the first adhesive layer is reliably bonded to the first display portion. The third sealant also extends to the left to the upper surface of the portion laminated and fixed to the first wrapping edge to seal the gap between the first reinforcement portion and the first wrapping edge.

[0037] By providing the first reinforcement part to strengthen the strength of the position where the first mounting hole is provided in the first housing, and then providing the third sealing member on the first reinforcement part, the first reinforcement part can be prevented from being corroded. In addition, the first reinforcement part and the rotating mechanism can be prevented from being in a salt spray environment at the same time, which can cause the first reinforcement part to be corroded faster.

Then, the second middle frame is completely isolated from the rotating mechanism by the fourth sealing part of the fourth sealing member. Even if the foldable electronic device falls into the seawater, the second middle frame and the rotating mechanism will not be in contact with the seawater at the same time, so as to prevent the second middle frame from being accelerated to corrode when the second middle frame and the rotating mechanism are electrically connected and immersed in the seawater at the same time. Specifically, there is a gap between the edge of the second adhesive layer and the edge of the fourth sealing part, or the edge of the second adhesive layer is in contact with the edge of the fourth sealing part. In this way, the fourth sealing part can be prevented from affecting the second adhesive layer, ensuring that the second adhesive layer can reliably bond to the second display part of the display screen; and the fourth sealing part can reliably seal the second avoidance area.

[0065] The number of the second mounting holes may be multiple, and the multiple second mounting holes are respectively used to install components such as a volume button, a power button, a subscriber identity module (SIM) card tray, etc. Some of the second mounting holes are located on the right side of the second housing, and other second mounting holes may be located on the front side or the rear side of the second housing.

[0066] The second mounting hole located on the right side of the second shell is described in detail. The second reinforcement portion is fixed to the top of the right side portion of the second covering frame, and the upper surface of the second reinforcement portion is flush with the upper surface of the second support plate. A portion of the second adhesive layer is bonded to a portion of the upper surface of the second reinforcement portion. Another portion of the upper surface of the second reinforcement portion is distributed to the left and right of the second wrapping edge of the second covering frame, and another portion of the upper surface of the second reinforcement portion is located between the second wrapping edge and the second adhesive layer. The position of another portion of the upper surface of the second reinforcement portion is the above-mentioned second interval, and another portion of the upper surface of the second reinforcement portion is the above-mentioned second exposed area.

[0067] In the height direction of the foldable electronic device, the orthographic projection of a portion of the second adhesive layer on the second support plate is completely offset from the orthographic projection of the sixth seal on the second support plate. Specifically, there is a gap between the right edge of a portion of the second adhesive layer and the left edge of the sixth seal, or the right edge of a portion of the second adhesive layer is in contact with the left edge of the sixth seal. In this way, the sixth seal can be prevented from affecting the second adhesive layer, ensuring that the second adhesive layer is reliably bonded to the second display portion. The sixth seal also extends to the right to the upper surface of the portion laminated and fixed to the second wrapping edge to seal the gap between the second reinforcement portion and the second wrapping edge.

[0068] By providing the second reinforcement part to strengthen the strength of the position where the second mounting hole is provided in the second housing, and then providing the sixth sealing member on the second reinforcement part, the second reinforcement part can be prevented from being corroded. In addition, the second reinforcement part and the rotating mechanism can be prevented from being in a salt spray environment at the same time, which can cause the second reinforcement part to be corroded faster.

[0069] In some embodiments, the second carrier, the second support plate and the second support frame enclose a second installation cavity; the second housing further comprises a second back plate, which is fixed to a side of the second support frame away from the second support plate, and the second back plate closes the second installation cavity. The second back plate can be made of glass, ceramic or stainless steel, and is used to protect the components in the second installation cavity and to form the appearance of the foldable electronic device.

[0070] In some embodiments, the second protective member is made of plastic, Mylar, insulating paint or insulating glue; or, the second protective member is formed by performing micro-arc oxidation treatment on the outer surface of the second middle frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0105] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0106] See also Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the structure of a foldable electronic device provided in an embodiment of the present application, Figure 2 yes Figure 1 A schematic diagram of the structure of a foldable electronic device in another state is shown in FIG.

[0107] Figure 1 The foldable electronic device 1000 is shown in a folded state. Figure 2 The foldable electronic device 1000 is shown in an unfolded state. Figure 2 The unfolding angle of the foldable electronic device 1000 is 180 degrees. The foldable electronic device 1000 includes but is not limited to a cell phone, a notebook computer, a tablet personal computer, a personal digital assistant, a wearable device or a mobile device, etc. In the embodiment of the present application, the foldable electronic device 1000 is taken as a mobile phone for example.

[0108] It should be noted that the angles illustrated in the embodiments of the present application are allowed to have slight deviations. Figure 2 The unfolding angle of the foldable electronic device 1000 shown as 180 degrees means that it can be 180 degrees or approximately 180 degrees, such as 170 degrees, 175 degrees, 185 degrees, and 190 degrees, etc. The angles described below as examples can be understood in the same way.

[0109] For ease of description, the width direction of the foldable electronic device 1000 is defined as the X direction, the length direction of the foldable electronic device 1000 is defined as the Y direction, and the thickness direction of the foldable electronic device 1000 is defined as the Z direction. The X direction, the Y direction, and the Z direction are perpendicular to each other.

[0110] The foldable electronic device 1000 includes a main body 100 and a display screen 200, and the display screen 200 is installed on the main body 100. The display screen 200 includes a display surface and a mounting surface, and the display surface and the mounting surface are arranged opposite to each other. The display surface is used to display text, images, videos, etc. The display screen 200 includes a first display part 210, a second display part 220 and a third display part 230. The third display part 230 is located between the first display part 210 and the second display part 220, and the third display part 230 is flexible and can be bent along the X direction. The first display part 210 and the second display part 220 can actually be bent when they are not fixed.

[0111] In this embodiment, the display screen 200 adopts a flexible display screen 200, for example, an organic light emitting diode (OLED) display screen 200, an active-matrix organic light emitting diode or an active-matrix organic light emitting diode (AMOLED) display screen 200, a mini organic light emitting diode (mini organic light emitting diode) display screen 200, a micro organic light emitting diode (micro organic light-emitting diode) display screen 200, a micro organic light emitting diode (micro organic light-emitting diode) display screen 200, and a quantum dot light emitting diode (QLED) display screen 200.

[0112] Please refer to Figure 3 and Figure 4 , Figure 3 yes Figure 2 Schematic diagram of the split structure of the foldable electronic device shown in. Figure 4 yes Figure 3 A schematic diagram of the split structure of the main body of a foldable electronic device is shown in FIG.

[0113] The main body 100 includes a first housing 10, a second housing 20, a rotating mechanism 30, a first connecting member 40 and a second connecting member 50. In this embodiment, the first connecting member 40 and the second connecting member 50 can both be bolts. In other embodiments, the first connecting member 40 and the second connecting member 50 can also be fasteners such as screws.

[0114] The rotating mechanism 30 is installed on the first shell 10 and the second shell 20, and the rotating mechanism 30 is fixedly connected to the first shell 10 through the first connecting member 40, and the rotating mechanism 30 is fixedly connected to the second shell 20 through the second connecting member 50; so as to realize the rotation connection between the first shell 10 and the second shell 20, and the first shell 10 and the second shell 20 can rotate relative to each other through the rotating mechanism 30, so that the main body 100 switches between the folded state and the unfolded state. Specifically, the first shell 10, the second shell 20 and the rotating mechanism 30 are arranged in sequence along the X direction, and the sum of the dimensions between the three is the dimension of the main body 100 in the X direction (including the assembly tolerance and the assembly gap between the three). The dimension of the main body 100 in the X direction is the same as the dimension of the display screen 200 and the foldable electronic device 1000 in the X direction, and the same here includes the allowable tolerance range. The first shell 10, the second shell 20 and the rotating mechanism 30 have the same dimensions in the Y direction, and the same dimensions can allow for assembly or production tolerances. The dimensions of the first housing 10, the second housing 20 and the rotating mechanism 30 along the Y direction are the dimensions of the main body 100 in the Y direction, and the dimensions of the main body 100 in the Y direction are the same as the dimensions of the display screen 200 and the foldable electronic device 1000 in the Y direction. Of course, a small amount of deviation (assembly and production tolerance) may be allowed for the sameness here.

[0115] The relative rotation of the first shell 10 and the second shell 20 makes the main body 100 in the folded state, which means that the first shell 10 and the second shell 20 are rotated by the rotating mechanism 30 and approach each other, and the surfaces of the first shell 10 and the second shell 20 that carry the display screen 200 are opposite. In the application process, when the main body 100 is in the fully folded state, after the display screen 200 installed in the first shell 10 and the second shell 20 is folded, the display surface of the display screen 200 located in the first display part 210 and the display surface located in the second display part 220 are partially or completely in contact.

[0116] The first shell 10 and the second shell 20 rotate relative to each other so that the main body 100 is in the unfolding process (the first shell 10 and the second shell 20 can stay at any angle, such as a 90-degree angle, a degree angle, etc. between the first shell 10 and the second shell 20, that is, the display screen 200 is in a semi-expanded state), the first shell 10 and the second shell 20 rotate through the rotating mechanism 30, and move away from each other, and the angle between the first shell 10 and the second shell 20 becomes larger and larger until the first shell 10 and the second shell 20 rotate relative to each other so that the main body 100 is unfolded and in the unfolded state, and the angle between the first shell 10 and the second shell 20 can be close to 180 degrees or equal to 180 degrees. The first shell 10 and the second shell 20 are roughly in a flat state. At the same time, the first shell 10 and the second shell 20 are relatively far away from each other to drive the display screen 200 to unfold until the foldable electronic device 1000 is in the unfolded state, wherein the first shell 10 and the second shell 20 are relatively far away from each other to drive the display screen 200 to further unfold until the foldable electronic device 1000 is in the unfolded state.

[0117] The side of the first shell 10 and the second shell 20 facing away from the display screen 200 is the outer surface of the foldable electronic device 1000, and the side bearing the display screen 200 is the inner side.

[0118] The display screen 200 is mounted on the main body 100, and the mounting surface is fixedly connected to the main body 100. Specifically, the first housing 10 carries the first display portion 210, and the second housing 20 carries the second display portion 220. In other words, the first display portion 210 is mounted on the first housing 10, and the second display portion 220 is mounted on the second housing 20. Among them, the rotating mechanism 30 is arranged opposite to the third display portion 230, and the width dimension of the third display portion 230 is larger than the rotating mechanism 30, that is, a part of the third display portion 230 extends to the left to be opposite to the first housing 10, and another part of the third display portion 230 extends to the right to be opposite to the second housing 20, so as to realize the bending of the display screen 200.

[0119] See also Figure 2 The first shell 10 and the second shell 20 rotate relative to each other through the rotating mechanism 30. When the foldable electronic device 1000 is in the unfolded state, the display screen 200 has a large display area, realizing the large-screen display and operation functions of the foldable electronic device 1000, and improving the user experience. Figure 1 When the foldable electronic device 1000 is in a folded state, the display screen 200 is between the first shell 10 and the second shell 20. The first shell 10 and the second shell 20 protect the display surface of the display screen 200, which can greatly reduce the probability of the display screen 200 being damaged, and the overall size is reduced, which is easy to carry.

[0120] It should be noted that the directional terms such as “top”, “bottom”, “upper”, “lower”, “left”, “right”, “front” and “back” used in the embodiment of the present application to describe the foldable electronic device 1000 are mainly based on the foldable electronic device 1000 in the attached Figure 2 as well as Figure 3 The display orientation is explained in the figure, with the positive direction of the Z axis being the "top" and "upper", the negative direction of the Z axis being the "bottom" and "lower", the positive direction of the X axis being the "right", the negative direction of the X axis being the "left", the positive direction of the Y axis being the "back", and the negative direction of the Y axis being the "front". It does not constitute a limitation on the orientation of the foldable electronic device 1000 in actual application scenarios.

[0216] In this embodiment, the first middle frame 11 and the second middle frame 21 are made of a first metal. The first metal is a lightweight metal such as a magnesium-aluminum alloy, a magnesium alloy, a magnesium-lithium alloy, and an aluminum-lithium alloy. In other words, the first middle frame 11 is entirely made of lightweight metal. Compared with the first middle frame 11 and the second middle frame 21 made of aluminum alloy in the prior art, the weight of the first middle frame 11 in this embodiment is reduced, which reduces the weight of the first shell 10, and the weight of the second middle frame 21 is reduced, which reduces the weight of the second shell 20, and finally reduces the weight of the foldable electronic device 1000.

[0217] Those skilled in the art can understand that the area of ​​the first middle frame 11 exposed outside the first closed area and the area of ​​the second middle frame 21 exposed outside the second closed area are easily corroded. The first avoidance area 113C, the first exposed area 113E, the first connecting boss 115, and the hole wall surface of the first connecting hole 116 are the areas exposed outside the first closed area, and the second avoidance area 213C, the second exposed area 213E, the second connecting boss 215, and the hole wall surface of the second connecting hole 216 are the areas exposed outside the second closed area. In this embodiment, by setting the first protective member 14, the first protective member 14 includes a first sealing member 14A, a second sealing member 14B and a third sealing member 14C, so as to realize the protection of the hole wall surface of the first avoidance area 113C, the first exposed area 113E, the first connecting boss 115 and the first connecting hole 116, and prevent the area of ​​the first middle frame 11 exposed outside the first closed area from being corroded. By setting the second protective member 24, the second protective member 24 includes a fourth seal 24A, a fifth seal 24B and a sixth seal 24C, so as to protect the second avoidance area 213C, the second exposed area 213E, the second connecting boss 215 and the hole wall surface of the second connecting hole 216, and prevent the area of ​​the second middle frame 21 exposed outside the second closed area from being corroded.

The second spring piece is provided to make the second connecting block 33 contact with the second middle frame 21, so that the second connecting block 33 and the second middle frame 21 are electrically connected. In this way, the first middle frame 11, the rotating mechanism 30 and the second middle frame 21 are grounded together. An antenna is installed in the first installation cavity 119 of the first shell 10, and a resonant circuit is installed in the second installation cavity 217 of the second shell 20. After the first middle frame 11, the rotating mechanism 30 and the second middle frame 21 are grounded together, the antenna and the resonant circuit can be better tuned.

[0219] As is well known, when the first metal and the second metal are immersed in a salt spray environment such as seawater, and when the first metal and the second metal are electrically connected, the first metal will be rapidly corroded by the seawater, causing the surface of the first metal to rust rapidly. In this embodiment, the first bearing bottom plate 111 and the first bearing side plate 112 of the first frame 12 support a part of the rotating mechanism 30, the second bearing bottom plate 211 and the second bearing side plate 212 of the second frame 22 are made into another part of the rotating mechanism 30, and the first frame 12 and the second frame 22 are both made of insulating materials, that is, the rotating mechanism 30 is not in direct contact with the first middle frame 11 and the second middle frame 21. Then, the first middle frame 11 and the rotating mechanism 30 are completely isolated by the first seal 14A, the second seal 14B and the third seal 14C, and the second middle frame 21 and the rotating mechanism 30 are completely isolated by the fourth seal 24A, the fifth seal 24B and the sixth seal 24C. Even if the foldable electronic device 1000 enters a salt spray environment, for example, when the foldable electronic device 1000 falls into sea water, the first middle frame 11 and the rotating mechanism 30 can be prevented from being immersed in sea water at the same time, and the second middle frame 21 and the rotating mechanism 30 can be prevented from being immersed in sea water at the same time, thereby preventing the first middle frame 11 and the second middle frame 21 from being corroded.

[0220] In this embodiment, the first seal 14A, the second seal 14B, the third seal 14C, the fourth seal 24A, the fifth seal 24B and the sixth seal 24C are all plastic sheets, and the thickness of the plastic sheet is between 0.1 mm and 0.6 mm, for example, the thickness of the plastic sheet is 0.1 mm, 0.2 mm, 0.25 mm, 0.28 mm, 0.32 mm, 0.38 mm, 0.45 mm, 0.5 mm, 0.55 mm, 0.6 mm, etc. Thus, the first middle frame 11 and the rotating mechanism 30 can be well isolated, and the second middle frame 21 and the rotating mechanism 30 can be isolated, and the processing cost is low.

[0221] In other embodiments, the first seal 14A, the second seal 14B, the third seal 14C, the fourth seal 24A, the fifth seal 24B and the sixth seal 24C may also be made of insulating paint, Mylar sheet, insulating glue, etc. The thickness of the insulating paint is between 0.01 mm and 0.1 mm, for example, the thickness of the insulating paint is 0.01 mm, 0.03 mm, 0.05 mm, 0.07 mm, 0.09 mm or 0.1 mm, etc. The insulating paint is thin, which is conducive to the lightweight design of the first middle frame 11 and the second middle frame 21. The thickness of the Mylar sheet is between 0.01 mm and 0.1 mm, for example, it can be 0.01 mm, 0.02 mm, 0.04 mm, 0.06 mm, 0.08 mm, 0.1 mm, etc.

[0222] In other embodiments, micro-arc oxidation may be used to form the first seal 14A, the second seal 14B and the third seal 14C on the first middle frame 11 , and micro-arc oxidation may be used to form the fourth seal 24A, the fifth seal 24B and the sixth seal 24C on the second middle frame 21 .

[0223] In other embodiments, refer to Fig.33 , Fig.33 It is a partial cross-sectional enlarged view of a foldable electronic device provided by another embodiment of the present application. The first sealing portion 141 of the first sealing member 14A also extends to be stacked below the first bonding section 151, that is, the first sealing portion 141 extends to be fixed between the first bonding section 151 and the upper surface of the first support plate 113. Thus, even if the width dimension of the first avoidance area 113C is small, the first sealing portion 141 can be set to isolate the first middle frame 11 and the rotating mechanism 30. The third sealing portion 241 of the fourth sealing member 24A also extends to be stacked below the fifth bonding section 251, that is, the third sealing portion 241 extends to be fixed between the fifth bonding section 251 and the upper surface of the second support plate 213. Thus, even if the width dimension of the second avoidance area 213C is small, the third sealing portion 241 can be set to isolate the second middle frame 21 and the rotating mechanism 30.
