[0001] [Related Applications] This application claims priority to Chinese Patent Application No. 2022103344797, filed with the State Intellectual Property Office of the People's Republic of China on March 31, 2020, entitled "FOLDABLE ELECTRONIC DEVICE," which is incorporated herein by reference in its entirety.

[0002] [Technical field] The present application relates to the electronics field, in particular to foldable electronic devices. [Background technology]

[0003] At present, foldable electronic devices are gradually becoming popular in the market. Take the foldable smartphone, which is characterized by a flexible and foldable screen, for example. After folding, the size of the screen is similar to that of a general smartphone, and the foldable smartphone with a folded screen is easy to carry and use. After the screen is unfolded, the size of the screen is similar to that of a tablet computer, and it is convenient to use entertainment and office functions on the unfolded screen. The foldable smartphone has the advantages of an electronic device and a tablet computer, and meets the needs of current consumers. However, the foldable screen is easily damaged due to its large area and frequent folding action. Therefore, the protection of the screen is very important. The place where a foldable electronic device is most likely to be damaged is the end of the folding part of the screen. Therefore, how to effectively increase the strength of the end of the folding part becomes an unavoidable problem for the foldable electronic device. Summary of the Invention

[0004] An object of the present application is to provide a foldable electronic device with a high-strength edge appearance shielding member.

[0005] According to a first aspect, the present application provides a foldable electronic device including a first housing, a second housing, a central shaft assembly, and two shielding members. In a first direction, the first housing and the second housing are respectively coupled to both sides of the central shaft assembly, and the central shaft assembly rotates the first housing and the second housing relatively. Each shielding member includes a first shielding body, a second shielding body, and a third shielding body. The second shielding body and the third shielding body are located on both sides of the first shielding body, and both the second shielding body and the third shielding body are rotatable relative to the first shielding body. In a second direction, the second shielding body is disposed on a side of the first shielding body facing the central shaft assembly and is partially stacked with the first shielding body, and the third shielding body is disposed on a side of the first shielding body facing the central shaft assembly and is partially stacked with the first shielding body.

[0006] In the second direction, the two shielding members are located at both ends of the central shaft assembly, the first shielding body is coupled to one end of the central shaft assembly, the second shielding body is slidably rotatable relative to the first housing, and the third shielding body is slidably rotatable relative to the second housing. The first shielding body, the second shielding body, and the third shielding body form a part of the exterior structure of the foldable electronic device. The first direction is perpendicular to the second direction.

[0007] In this embodiment of the present application, the first shield, the second shield, and the third shield jointly form part of the exterior structure of the foldable electronic device. The second shield and the third shield are partially stacked with the first shield, i.e., have overlapping parts, and are not directly subjected to impact loads, so that the impact load on the first shield is resolved to the two sides of the first and second housings to protect the internal components. The possibility of misalignment between the first shield, the second shield, and the third shield is reduced, and the structural stability of the foldable electronic device is improved. In addition, the first shield, the second shield, and the third shield can shield the internal components of the space in which the central shaft assembly is disposed, and the appearance of the foldable electronic device can be made more beautiful. The shielding members are respectively disposed at the two ends of the central shaft assembly, which can further provide a uniform shielding effect for the two ends of the central shaft assembly, and can make the appearance of the foldable electronic device more simple.

[0008] In a possible implementation, the exterior surfaces of the first shield, the second shield, and the third shield jointly form an exterior surface of an exterior structure. The exterior surface of the exterior structure faces the same direction as the exterior surfaces of the first housing and a part of the second housing. The exterior surfaces of the second shield and the third shield are located in a gap between the first shield and the first housing and a gap between the first shield and the second housing, respectively.

[0009] In the unfolded state of the foldable electronic device, the first and second housings are flattened against each other, and the first housing, the second shield, the first shield, the third shield and the second housing are arranged sequentially in a first direction. In the folded state of the foldable electronic device, the first and second housings are folded to face each other, and the second and third shields are separately rotated by a specific angle relative to the first shield.

[0010] It is understood that in the unfolded state of the foldable electronic device, the first shielding body, the second shielding body, and the third shielding body cover the gap between the first housing and the second housing, and the end face of the folding position of the foldable electronic device in the unfolded state is covered by the shielding member, thereby protecting the internal components and simplifying the external structure of the foldable electronic device. In the folded state of the foldable electronic device, the first shielding body, the second shielding body, and the third shielding body rotate relative to each other as the central shaft assembly rotates, and can completely cover and protect the folded central shaft end face, and can bend at an angle as the first housing and the second housing are folded to face each other.

[0011] In a possible implementation, the first shield includes a main shield and a limiting body coupled to the central shaft assembly. The limiting body is arranged convexly on a side of the main shield, limiting blocks are arranged on both sides of the limiting body, and the second shield and the third shield are each located on two opposite sides of the limiting body. The second shield is partially stacked with the main shield, and the third shield is partially stacked with the first shield. The two opposite sides of the second shield each have a rotation gap facing the side of the limiting body and the end face of the first housing, and the two opposite sides of the third shield each have a rotation gap facing the other side of the limiting body and the end face of the second housing.

[0012] It can be seen that there is a rotation gap between one side of the second shield and the limiting body of the first shield, and the other side of the second shield is opposite and spaced apart from the end of the first housing. There is a rotation gap between one side of the third shield and the limiting body of the first shield, and the other side of the third shield is opposite and spaced apart from the end of the second housing. The second shield can rotate relative to the adjacent first housing and first shield when the foldable electronic device is folded or unfolded, and the third shield can rotate relative to the adjacent second housing and first shield when the foldable electronic device is folded or unfolded, and the first housing, the second shield, the first shield, the third shield, and the second housing can rotate relative to each other and limit each other in sequence. Therefore, the structure of the foldable electronic device is stable during use and is not easily damaged.

[0013] In a possible implementation, the two opposing sides of the limiting body include concave curved surfaces, the second shielding body includes two oppositely arranged arcuate convex surfaces, and the third shielding body includes two oppositely arranged arcuate convex surfaces. One of the arcuate convex surfaces of the second shielding body has a rotation gap opposite one of the concave curved surfaces, and one of the arcuate convex surfaces of the third shielding body has a rotation gap opposite the other of the concave curved surfaces. The other of the arcuate convex surfaces of the second shielding body is spaced opposite an end surface of the first housing, and the other of the arcuate convex surfaces of the third shielding body is spaced opposite an end surface of the second housing. When an external force acts on an end of the electronic device, there are overlapping portions between the second shielding and the first shielding, and between the first shielding and the third shielding, and the first housing, the second shielding, the first shielding, the third shielding, and the second housing abut against each other in sequence, restricting each other in sequence, thereby cushioning and reducing the impact force between them, and avoiding the impact on the lifespan of the electronic device due to damage to the shielding members.

[0014] It can be seen that the concave curved surface is arranged to cooperate with the arc-shaped convex surface, so that the rotation between the limiting body and the second or third shielding body is smoother and more stable, and the reliability of the folding and unfolding process of the foldable electronic device can be ensured. The concave curved surface can further restrict the arc-shaped convex surface at multiple angles, which can improve the stability of the relative movement between the first and second shielding bodies and improve the structural reliability of the foldable electronic device.

[0015] In a possible implementation, the first shield is rotatably coupled to the second shield and the third shield separately via a rotation axis, and both the second shield and the third shield are rotatably coupled to the first housing and the second housing separately via a rotation axis.

[0016] Since the second shield is separately connected to the first shield and the first housing via a rotating shaft, the connection manner is stable, and the second shield rotates more efficiently and stably. Since the third shield is separately connected to the first shield and the second housing via a cylinder, the connection strength between the third shield and the first shield and the connection strength between the third shield and the end of the second housing can be increased. When an impact occurs, displacement is unlikely to occur, and damage to other structures of the folding electronic device can be minimized.

[0017] In a possible implementation, the first shield, the second shield and the third shield comprise a metallic material.

[0018] In usage scenarios, such as high temperature or long-term bending scenarios, metal materials can avoid deformation that is difficult to recover from, ensure the aesthetic appearance of foldable electronic devices, and improve product competitiveness.

[0019] In a possible implementation, the limiting body has an arcuate end surface and two sliding surfaces arranged opposite each other, each sliding surface being coupled to one end of the arcuate end surface, the limiting block being located at a position close to the arcuate end surface of the sliding surface, each limiting block being provided with a concave curved surface, and the two concave curved surfaces being smoothly coupled to both ends of the sliding surface.

[0020] It is understood that the smooth coupling between the concave curved surface and the sliding surface can simplify the movement process of the second shield and the third shield. The second shield and the third shield can rotate respectively under the constraint of the concave curved surface. In the folded state of the foldable electronic device, the sliding surface can abut against one side of the second shield or the third shield.

[0021] In a possible implementation, the first housing includes a first sub-bezel and a second sub-bezel arranged opposite to each other. The first sub-bezel is provided with a first end surface and a first appearance body arranged convexly on the first end surface, and the second sub-bezel is provided with a second end surface and a second appearance body arranged convexly on the second end surface. In the first direction, the first shielding body is located between the first appearance body and the second appearance body. The second shielding body is partially stacked with the first appearance body, and the arc-shaped convex surface of the second shielding body is spaced opposite to the first end surface. The third shielding body is partially stacked with the third appearance body, and the arc-shaped convex surface of the third shielding body is spaced opposite to the second end surface.

[0022] It can be seen that the first exterior body is partially stacked with the second shielding body, and another portion of the second shielding body is stacked with the first shielding body. The second exterior body is partially stacked with the third shielding body, and another portion of the third shielding body is stacked with the first shielding body. In the unfolded or folded state of the foldable electronic device, the first sub-bezel, the second shielding member, the first shielding member, the third shielding member, and some sides of the third sub-bezel form an exterior surface of one side of the foldable electronic device, and completely shield the internal components from this side, thereby simplifying the appearance of the foldable electronic device and protecting the internal components.

[0023] In a possible implementation, the second shield further includes a first side and a second side arranged opposite to each other, and the third shield further includes a third side and a fourth side arranged opposite to each other. In a folded state of the foldable electronic device, the first side is spaced opposite to one sliding surface, the second side is spaced opposite to the first end surface, the third side is spaced opposite to the other sliding surface, and the fourth side is spaced opposite to the second end surface.

[0024] It is understood that in the folded state of the foldable electronic device, the first sub-bezel, the second shield, the first shield, the third shield, and the third sub-bezel are sequentially restrained via opposing surfaces to maintain the stability of the folded state of the foldable electronic device.

[0025] In a possible implementation, the two arc-shaped convex surfaces of the second shield are a first arc-shaped convex surface and a second arc-shaped convex surface. The second shield further includes a first top surface, a first bottom surface, a first surface, and a second surface. The first side surface, the first arc-shaped convex surface, the first top surface, the second arc-shaped convex surface, the second side surface, and the first bottom surface are sequentially coupled and all coupled to the first surface and the second surface. The first surface is disposed opposite to the second surface, and the first side surface and the second side surface are separately disposed at an included angle with respect to the first bottom surface, and the first surface is the exterior surface of the first shield. In a possible implementation, the two arc-shaped convex surfaces of the third shield are a third arc-shaped convex surface and a fourth arc-shaped convex surface. The third shield further includes a second top surface, a second bottom surface, a third surface, and a fourth surface. The third side surface, the third arc-shaped convex surface, the second top surface, the fourth arc-shaped convex surface, the fourth side surface, and the second bottom surface are sequentially combined to form a third surface and a fourth surface. The third surface and the fourth surface are disposed opposite each other. The third side surface and the fourth side surface are separately disposed at an angle to the second bottom surface, and the third surface is an exterior surface of the third shielding body.

[0026] In the folded state of the foldable electronic device, the first top surface, the arc-shaped end surface of the first shielding member, and the fifth arc-shaped surface can be substantially integrally formed into an arc shape. The arc shape can make the appearance of the first shielding body, the second shielding body, and the third shielding body more simple, and is compatible with the angle obtained after the first housing and the second housing are separately rotated via the central shaft assembly. In the folded state of the foldable electronic device, the first bottom surface, the second bottom surface, the bottom surface of the first sub-bezel, and the bottom surface of the third sub-bezel can be in the same plane, and the overall structure is more simple when the foldable electronic device is in the unfolded state.

[0027] In a possible implementation, the rotation axis of the first shielding body is a first rotation axis and a second rotation axis. The rotation axis of the first outer body is a third rotation axis, and the rotation axis of the second outer body is a fourth rotation axis. The second shielding body includes a first through hole and a second through hole, and the third shielding body includes a third through hole and a fourth through hole. The first rotation axis passes through the first through hole, and the second shielding body rotates relative to the first shielding body via the first rotation axis, the second rotation axis passes through the third through hole, and the third shielding body rotates relative to the first shielding body via the second rotation axis, the third rotation axis passes through the second through hole, and the first housing and the second shielding body rotate via the third rotation axis, and the fourth rotation axis passes through the fourth through hole, and the second housing and the third shielding body rotate via the fourth rotation axis.

[0028] In a possible implementation, the foldable electronic device includes a display, and the first housing, the second housing, the central shaft assembly, and the shielding member form a body. The display is stacked with the body, and the display includes a first portion, a second portion, and a third portion connecting the first portion and the second portion. The first housing carries the first portion, the second housing carries the second portion, and the central shaft assembly supports the third portion. The central shaft assembly drives the third portion to bend.

[0029] In the folded state of the foldable electronic device, the first part and the second part face each other, or the first part and the second part face away from each other.

[0030] It can be understood that in the folded state of the foldable electronic device, the first and second housings rotate separately via the central shaft assembly and are close to each other. The faces of the first and second housings that carry the display face each other. After folding, the display is inside the structure of the main body. Alternatively, the faces of the first and second housings that carry the display face each other oppositely. After folding, the display is outside the structure. In other words, the foldable electronic device may be an inside folding screen electronic device or an outside folding screen electronic device. The first shield, the second shield, and the third shield can jointly form part of the exterior structure of the foldable electronic device. Since the second and third shields are partially stacked with the first shield, i.e., have overlapping portions, and are not directly subjected to impact loads, the impact load on the first shield is resolved to the first and second housings on the two sides, thereby protecting the display from impact.

[0031] In a possible implementation, the central shaft assembly includes a base, a first rotating section, and a second rotating section. The base includes a first end and a second end, the first rotating section includes a third end and a fourth end, and the second rotating section includes a fifth end and a sixth end. Two first shields are coupled to the first end and the second end, respectively, two second shields are disposed at the third end and the fourth end, respectively, and two third shields are disposed at the fifth end and the sixth end, respectively.

[0032] It can be seen that the first shield may be directly coupled to the two ends of the base. The second shield may not be coupled to the first rotating part, and the third shield may not be coupled to the second rotating part, and only the positions are mutually limited. When the central shaft assembly is impacted, the gap between the first shield and the second shield and the gap between the first shield and the third shield are small. The first shield, the second shield, and the third shield may sequentially limit each other to buffer the external force. When the central shaft assembly is subjected to an external force, the first shield may receive the main impact load, and the second shield and the third shield may buffer the external force against the first shield without directly receiving the impact load. In addition, the positions of the base and the first rotating part are limited to each other, and the positions of the base and the second rotating part are limited to each other, thereby reducing the displacement of the misalignment of the base, the first rotating part, and the second rotating part that are impacted by the external force, reducing the deformation of the display, and increasing the mechanical strength of the foldable electronic device. Similarly, when the second shield or the third shield receives an external force, a part of the energy of the impact is transferred to the first shield to disperse the impact force, thereby reducing the positional deviation of the first shield, the second shield, the third shield, and the central shaft assembly, and effectively protecting the display. When the foldable electronic device is dropped in the unfolded state, the first housing or the second housing may receive the impact first, and the impact force may be transferred from the first sub-bezel to the second shield adjacent to the first sub-bezel. Alternatively, the third sub-bezel may transfer the impact force to the third shield, and the second and third shields may transfer a part of the impact force back to the first shield, thereby dispersing the impact force, reducing the positional deviation of the first shield, the second shield, the third shield, and the central shaft assembly, and effectively protecting the display. Since the second shield is not directly connected to the first rotating part, the movements of the second shield and the first rotating part do not affect each other. When the second shield receives an impact from an external force, the movement function of the first rotating part is not affected, so the impact that the first rotating part gives to the display is reduced, protecting the display.

[0048] The following describes in detail specific implementations of the present application with reference to the accompanying drawings. Although the accompanying drawings show exemplary implementations of the present application, it should be understood that the present application may be implemented in other ways different from those described herein. Therefore, the present application is not limited to the following implementations.

[0049] For ease of understanding, the terms in the embodiments of the present application are first explained.

[0050] "Plurality" means "two or more."

[0051] Bonding should be understood in a broad sense. For example, when A is bonded to B, A may be directly bonded to B, or A and B may be indirectly bonded via an intermediate medium.

[0052] At present, foldable electronic devices are gradually becoming popular in the market. Take the foldable smartphone, which is characterized by a flexible and foldable screen, for example. After folding, the size of the screen is similar to that of a general smartphone, and the foldable smartphone with a folded screen is easy to carry and use. After the screen is unfolded, the size of the screen can be similar to that of a tablet computer, which is convenient for entertainment and office functions to be used on the unfolded screen. The foldable smartphone has the advantages of an electronic device and a tablet computer, and meets the needs of current consumers. However, the foldable screen is easily damaged due to its large area or frequent folding action. Therefore, the protection of the screen is very important. The place where a foldable electronic device is most likely to be damaged is the end of the folding part of the screen. Therefore, how to effectively increase the strength of the screen end of the folding part becomes an inevitable problem for the foldable electronic device.

[0053] In view of this, the present application provides a foldable electronic device that effectively increases the strength of the ends of the folding portion of the foldable electronic device to protect the internal components of the foldable electronic device.

[0054] Please refer to Figures 1, 2 and 3. Figure 1 is a schematic diagram of a structure of a foldable electronic device 1000 in a folded state according to an embodiment of the present application. Figure 2 is a schematic exploded view of a display 100 and a main body of the foldable electronic device 1000 according to an embodiment of the present application. Figure 3 is a schematic exploded view of a main body of the foldable electronic device 1000 according to an embodiment of the present application.

[0055] The foldable electronic device 1000 includes, but is not limited to, a smartphone, a notebook computer, a tablet personal computer, a personal digital assistant, a wearable device, a vehicle-mounted device, etc. In the present embodiment of the present application, an example in which the foldable electronic device 1000 is a smartphone will be described.

[0056] The foldable electronic device 1000 shown in the embodiment of the present application is an electronic device that can be folded once. The foldable electronic device 1000 may include two parts. The two parts can be folded close to each other in opposite directions until the foldable electronic device 1000 is in a folded state, and the two adjacent parts can be unfolded facing opposite each other until the foldable electronic device 1000 is in an unfolded state.

[0057] For ease of explanation, the width direction of the foldable electronic device 1000 is defined as the Y direction, the length direction of the foldable electronic device 1000 is defined as the X 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.

[0058] The foldable electronic device 1000 includes a display 100 and a body (not shown). The display 100 is mounted on the body. The display includes a display surface and a mounting surface, which are arranged opposite to each other. The display surface is configured to display text, images, videos, etc. The display 100 includes a first portion 110, a second portion 120, and a third portion 130. The third portion 130 is located between the first portion 110 and the second portion 120, and the third portion 130 is flexible and can be bent in the Y direction. In this embodiment, the display 100 is a flexible display, such as an organic light-emitting diode (OLED) display, an active matrix organic light-emitting diode or active matrix organic light-emitting diode (AMOLED) display, or a quantum dot light-emitting diode (QLED) display. The first and second portions 110, 120 can actually bend when not fastened.

[0059] The main body includes a first housing 200, a second housing 300, a central shaft assembly 400, and two shielding members 500. The first housing 200 is rotatably coupled to the second housing 300 via the central shaft assembly 400. The first housing 200 and the second housing 300 support the first portion 110 and the second portion 120, respectively. The central shaft assembly 400 drives the first housing 200 and the second housing 300 to fold and unfold. The first housing 200 and the second housing 300 may be folded to approach each other facing each other until the foldable electronic device 1000 is in a folded state. The first housing 200 and the second housing 300 may be unfolded away from each other in an opposite manner until the foldable electronic device 1000 is in an unfolded state, and the central shaft assembly 400 supports the foldable third portion 130 of the display 100.

[0060] In the first direction (Y-axis direction), the first housing 200 and the second housing 300 are respectively coupled to both sides of the central shaft assembly 400, and the central shaft assembly 400 rotates the first housing 200 and the second housing 300 relatively. Each shielding member 500 includes a first shielding body 510, a second shielding body 520, and a third shielding body 530, the second shielding body 520 and the third shielding body 530 being located on both sides of the first shielding body 510, and both the second shielding body 520 and the third shielding body 530 being rotatable with respect to the first shielding body 510. In the second direction, the second shielding body 520 is arranged on the side of the first shielding body 510 facing the central shaft assembly 400 and is partially stacked with the first shielding body 510, and the third shielding body 530 is arranged on the side of the first shielding body 510 facing the central shaft assembly 400 and is partially stacked with the first shielding body 510.

[0061] In the second direction (X-axis direction), the two shielding members 500 are located at both ends of the central shaft assembly 400, the first shielding body 510 is coupled to one end of the central shaft assembly 400, the second shielding body 520 is slidably rotatable relative to the first housing 200, and the third shielding body 530 is slidably rotatable relative to the second housing 300. The first shielding body 510, the second shielding body 520, and the third shielding body 530 form a part of the exterior structure of the foldable electronic device 1000. The first direction is perpendicular to the second direction.

[0062] The first shielding body 510, the second shielding body 520, and the third shielding body 530 jointly form the exterior surface of the exterior structure. The exterior surface of the exterior structure faces the same direction as the exterior surfaces of the first housing 200 and the second housing 300, and the exterior surfaces of the second shielding body 520 and the third shielding body 530 are respectively located in the gap between the first shielding body 510 and the first housing 200 and the gap between the first shielding body 510 and the second housing 300. In the unfolded state of the foldable electronic device 1000, the first housing 200 and the second housing 300 are flattened against each other, and the first housing 200, the second shielding body 520, the first shielding body 510, the third shielding body 530, and the second housing 300 are sequentially arranged in the first direction. When the foldable electronic device 1000 is in a folded state, the first housing 200 and the second housing 300 are folded facing each other, and the second shielding body 520 and the third shielding body 530 are rotated separately by specific angles relative to the first shielding body 510.

[0063] 2 merely illustrates an example of a coupling relationship between the display 100, the first housing 200, the second housing 300, the central shaft assembly 400, and the shielding member 500, and does not particularly limit the coupling positions, specific configurations, the number of parts, etc. The structure illustrated in this embodiment of the present application does not constitute a specific limitation on the foldable electronic device 1000. In some other embodiments of the present application, the foldable electronic device 1000 may include more or fewer components than those illustrated, some components may be combined and some components may be separated, or a different component arrangement may be used. The components in the figure may be implemented by hardware, software, or a combination of software and hardware.

[0064] In daily use, electronic devices with large screens may be more convenient to use, but electronic devices with large screens are inconvenient to carry around on a daily basis. The problem of electronic devices with large screens being inconvenient to carry around is solved by the emergence of foldable electronic devices. When the foldable electronic device 1000 is in an unfolded state, the screen size of the electronic device can be made larger than that of a general electronic device, thereby realizing the large screen display function and operation function of the foldable electronic device 1000, which can improve the user experience when the user watches videos and engages in entertainment. When the user does not need a large screen, the foldable electronic device 1000 can be folded, and the display 100 of the foldable electronic device 1000 with the electronic device screen facing outward in the folded state is half that of the foldable electronic device 1000 in the unfolded state. This facilitates one-handed operation by the user. The display 100 is located between the first housing 200 and the second housing 300. The first housing 200 and the second housing 300 protect the display surface of the display 100, and significantly reduce the probability of damage to the display 100. In addition, the overall dimensions are small, making the foldable electronic device easy to carry.

[0065] Further, refer to Fig. 3. The first housing 200 is provided with a first mounting groove (not shown), and the second housing is provided with a second mounting groove (not shown), and the first mounting groove and the second mounting groove are connected to form a mounting groove. A central shaft assembly 400 is attached to this mounting groove and fastened to the first housing 200 and the second housing 300, so that the first housing 200 and the second housing 300 are rotatably connected. The first housing 200 and the second housing 300 rotate relative to each other via the central shaft assembly 400, whereby the main body is switched between a folded state and an unfolded state.

[0066] Furthermore, both the first housing 200 and the second housing 300 are provided with an accommodating groove (not shown), which is configured to accommodate electronic elements such as a processor, a circuit board, a camera module, and structural components of an electronic device. The side of the central shaft assembly 400 facing away from the display 100 is the outer surface of the foldable electronic device 1000, and the side on which the display 100 is mounted is the inner surface. In practice, a bearing plate (not shown) is disposed on the inner surface of the first housing 200 and the second housing 300, which is used to pack the accommodating groove, on which the display 100 is mounted, and which supports the flexible display 100.

[0067] The first housing 200 includes a first intermediate frame 210 and a first bezel 220. The first intermediate frame 210 may be rectangular, the first bezel 220 surrounds three sides of the first intermediate frame 210, and the first mounting groove is located at the fourth side of the first intermediate frame 210. The first bezel 220 and the first intermediate frame 210 may be enclosed in the receiving groove, and the bearing plate may be arranged to support the first portion of the display. Specifically, the first bezel 220 includes two first sub-bezels 221 and one second sub-bezel 222. The two first sub-bezels 221 are respectively arranged on two short sides of the first housing 200. One end of the second sub-bezel 222 is coupled to one first sub-bezel 221, and the other end is coupled to the other first sub-bezel 221. The second sub-bezel 222 is located on the long side of the first housing 200. The first mounting groove is located between the two first sub-bezels 221 and faces the second sub-bezel 222, spaced apart.

[0068] Each of the first sub-bezels 221 includes a first end surface 2210 and a first exterior body 2211. The first end surface 2210 faces away from the second sub-bezel 222. The first exterior body 2211 is arranged in a convex shape on the first end surface 2210. In the X-axis direction, i.e., in the thickness direction of the first sub-bezel 221, the thickness of the first exterior body 2211 is smaller than the thickness of the first sub-bezel 221. The first exterior body 2211 has a first exterior surface (not shown) and a first inner side surface 2211a facing away from the first exterior surface. The first exterior surface is exposed to the outside of the electronic device and is on the same plane as the outer surface of the first sub-bezel 221. The first inner side surface 2211a is joined to the first end surface 2210 at an angle. In this embodiment, the angle is 90 degrees, which makes it easy to assemble the first sub-bezel 221 with the shielding member 500.

[0069] The second housing 300 includes a second intermediate frame 310 and a second bezel 320. The second intermediate frame 310 may be rectangular, the second bezel 320 surrounds three sides of the second intermediate frame 310, and the second mounting groove is located at the fourth side position. The second bezel 320 and the second intermediate frame 310 may be enclosed in the receiving groove, and the bearing plate may be arranged to support the second part 120 of the display 100. Specifically, the second bezel 320 includes two third sub-bezels 321 and one fourth sub-bezel 322. The two third sub-bezels 321 are respectively arranged on two short sides of the second housing 300. One end of the fourth sub-bezel 322 is coupled to one third sub-bezel 321, and the other end is coupled to the other third sub-bezel 321. The fourth sub-bezel 322 is located on the long side of the second housing 300. A second mounting groove (not shown) is located between the two third sub-bezels 321 and faces and is spaced apart from the fourth sub-bezel 322.

[0070] Each of the third sub-bezels 321 includes a second end surface 3210 and a second exterior body 3211. The second end surface 3210 faces away from the fourth sub-bezel 322. The second exterior body 3211 is arranged in a convex shape on the second end surface 3210. In the X-axis direction, that is, in the thickness direction of the third sub-bezel 321, the thickness of the second exterior body 3211 is smaller than the thickness of the third sub-bezel 321. The second exterior body 3211 has a second exterior surface (not shown) and a second inner side surface 3211a facing away from the second exterior surface. The second exterior surface is exposed to the outside of the electronic device and is on the same plane as the outer surface of the third sub-bezel 321. The second inner side surface 3211a is joined to the second end surface 3210 at an angle. In this embodiment, the angle is 90 degrees, which makes it easy to assemble with the shielding member 500.

[0071] The central shaft assembly 400 is disposed between the first housing 200 and the second housing 300, and is separately coupled to the first housing 200 and the second housing 300 via the first mounting groove and the second mounting groove. In the unfolded state of the foldable electronic device 1000, the first housing 200, the second housing 300, and the central shaft assembly 400 support the display 100 together. The first portion 110 faces the first housing 200, the second portion 120 faces the second housing 300, and the third portion 130 faces the central shaft assembly 400. In the folded state of the foldable electronic device 1000, the first housing 200 and the second housing 300 rotate separately via the central shaft assembly 400 and are close to each other. The surfaces of the first housing 200 and the second housing 300 that support the display 100 face each other. After folding, the display 100 is inside the structure of the main body. In the implementation, the surfaces of the first housing 200 and the second housing 300 that carry the display 100 face away from each other. After folding, the display 100 is outside the structure. In other words, the foldable electronic device 1000 may be an inside-foldable screen electronic device or an outside-foldable screen electronic device. This is not limited here.

[0072] The central shaft assembly 400 includes a base 410, a first rotating part 420, and a second rotating part 430. The first rotating part 420 and the second rotating part 430 are symmetrically coupled to both sides of the base 410. The base 410 and the first rotating part 420 may be rotatably coupled to each other, and the base 410 and the second rotating part 430 may be rotatably coupled to each other. The specific configuration may be a rotating shaft mechanism in the prior art. This will not be described here. The central shaft assembly 400 is configured to support the display 100. The first rotating part 420 is disposed in a first mounting groove of the first housing 200 and is rotatably coupled to the first housing 200 and the base 410. The second rotating part 430 is disposed in a second mounting groove of the second housing 300 and is rotatably coupled to the second housing 300 and the base 410. When the foldable electronic device 1000 is unfolded and folded, the first rotating unit 420 and the second rotating unit 430 rotate separately with respect to the base 410. When the unfolding and folding operations are completed, the first rotating unit 420 and the base 410 restrict each other, the base 410 and the second rotating unit 430 restrict each other, and the first rotating unit 420, the base 410, the second rotating unit 430, and both the first housing 200 and the second housing 300 restrict each other, so that the foldable electronic device 1000 can be positioned in an unfolded state, a folded state, or an intermediate state, and damage to the structure of the foldable electronic device 1000 due to excessive rotation of the first housing 200 and the second housing 300 can also be prevented.

[0073] The base 410, the first rotating part 420, and the second rotating part 430 each include two opposing ends. The base 410 includes a first end 411 and a second end 412, the first rotating part 420 includes a third end 421 and a fourth end 422, and the second rotating part 430 includes a fifth end 431 and a sixth end 432. The first end 411, the second end 412, the third end 421, the fourth end 422, the fifth end 431, and the sixth end 432 are configured to cooperate with the shielding member 500.

[0074] Please refer to Figures 4, 5, 6A, 6B, and 6C. Figure 4 is a schematic enlarged view of a partial structure of the foldable electronic device 1000 shown in Figure 3. Figure 5 is a schematic exploded view of the shielding member 500, a part of the first sub-bezel 221, and a part of the third sub-bezel 321 of the foldable electronic device 1000 according to an embodiment of the present application, which are arranged obliquely. Figure 6A is a schematic view of the structure of the first shielding body according to the present application. Figure 6B is a schematic view of the structure of the second shielding body according to an embodiment of the present application. Figure 6C is a schematic view of the structure of the third shielding body according to an embodiment of the present application.

[0075] There are two shields 500, which are separately arranged on both ends of the central shaft assembly 400 and are used as the exterior parts of the foldable electronic device 1000. The first housing 200, the second housing 300 and the shield 500 are housings of an electronic device, and the surface facing away from the display 100 forms the exterior surface of the foldable electronic device 1000. The two shielding members 500 are arranged symmetrically in the X-axis direction. The first shielding member 510 of the two shielding members 500 is separately arranged at the first end 411 and the second end 412 of the base 410. The second shielding member 520 of the two shielding members 500 is separately arranged at the third end 421 and the fourth end 422 of the first rotating part 420, and the two third shielding members 530 are separately arranged at the fifth end 431 and the sixth end 432 of the second rotating part 430.

[0076] The first shield 510, the second shield 520 and the third shield 530 jointly form part of the exterior structure of the foldable electronic device 1000, and can shield the interior components of the space in which the central shaft assembly 400 is disposed while protecting the interior components, thereby making the appearance of the foldable electronic device 1000 more beautiful. The shielding members 500 are separately disposed on two ends of the central shaft assembly 400, which can further provide a uniform shielding effect for the two ends of the central shaft assembly 400, making the appearance of the foldable electronic device more simple.

[0077] Please refer to FIG. 6A. The first shielding body 510 includes a main shielding body 511 and a limiting body 512. Specifically, the main shielding body 511 includes a main shielding body exterior surface 5110, a coupling surface 5111 facing away from the main shielding body exterior surface 5110, a first surface 5112 and a second surface 5113 arranged opposite to each other, and a third surface 5114 and a fourth surface (not shown) arranged opposite to each other. The first surface 5112, the third surface 5114, the second surface 5113, and the fourth surface are sequentially coupled to each other, and are all coupled to the coupling surface 5111 and the main shielding body exterior surface 5110 perpendicularly or at an angle therebetween. The third surface 5114 may be a convex surface that is an arc-shaped surface in this embodiment. Both ends of the arc-shaped surface are coupled to the first surface 5112 and the second surface 5113, respectively. The angle of the arc matches the bending angle of the central shaft assembly 400 after the central shaft assembly 400 is bent, and this arc surface is also an arc that accommodates the bending of the display 100.

[0078] The limiting body 512 may be a rectangular block body, and is disposed on a side surface of the main shielding body 511. Specifically, the limiting body 512 is disposed in a convex shape on the coupling surface 5111, specifically, the limiting body 512 is disposed at an intermediate position of the coupling surface 5111, and has two sliding surfaces 5121 disposed opposite to each other, a first coupling surface 5122, and an arc-shaped end surface 5123. The arc-shaped end surface is coupled to the two sliding surfaces 5121 and the first coupling surface 5122. The sliding surfaces 5121 are coupled to the coupling surface 5111, one sliding surface 5121 facing the same direction as the first surface 5112, and the other sliding surface 5121 facing the same direction as the second surface 5113. The first end 411 of the base 410 may be coupled to the first coupling surface 5122 of one limiting body 512 , and the second end 412 of the base 410 may be coupled to the first coupling surface 5122 of the other limiting body 512 .

[0079] Two limiting blocks 5124 are arranged in a convex shape on the limiting body 512. The limiting block 5124 is arranged at a position closer to the arc-shaped end surface 5123 of the two sliding surfaces 5121. The limiting block 5124 has a concave curved surface 5124a. The concave curved surface 5124a is smoothly coupled to the sliding surface 5121. The concave curved surface 5124a is an arc-shaped surface and is recessed into the back surface of the limiting block 5124, and the arc-shaped end surface 5123 of the limiting body 512 and the end surface of the limiting block 5124 are flush with the third surface 5114 of the main shielding body 511. A second shielding body 520 and a third shielding body 530 are arranged on both sides of the limiting body 512, respectively. The second shielding body 520 is partially stacked with the main shielding body 511, and the third shielding body 530 is partially stacked with the first shielding body 510. Both sides of the second shielding body 520 are in rotatable contact with the side surface of the limiting body 512 and the end surface of the first housing 200. Both sides of the third shielding body 530 are in rotatable contact with the other side surface of the limiting body 512 and the end surface of the second housing 300. The limiting block 5124 limits the second shielding body 520 and the third shielding body 530, respectively.

[0080] Refer to FIG. 6B. In the present application, the second shielding body 520 is shown as a sector-shaped block body, and includes a first side surface 5200, a first arc-shaped convex surface 5201, a first top surface 5202, a second arc-shaped convex surface 5203, a second side surface 5204, a first bottom surface 5205, a first surface 5206, and a second surface 5207. It can be understood that the second shielding body 520 includes two arc-shaped convex surfaces arranged opposite to each other, and the two arc-shaped convex surfaces include the first arc-shaped convex surface 5201 and the second arc-shaped convex surface 5203. The first surface 5206 and the second surface 5207 face opposite to each other. In the present application, the structure of the second shielding body 520 is shown as a sector with the first surface 5206 and the second surface 5207. It should be understood that the first surface 5206 and the second surface 5207 include, but are not limited to, shapes such as a sector, an ellipse, or a rectangle. The first side surface 5200, the first arc-shaped convex surface 5201, the first top surface 5202, the second arc-shaped convex surface 5203, the second side surface 5204, and the first bottom surface 5205 are connected in sequence. The first side surface 5200, the first arc-shaped convex surface 5201, the first top surface 5202, the second arc-shaped convex surface 5203, and the second side surface 5204 are connected in sequence smoothly. The first side surface 5200 and the first bottom surface 5205 are connected at an included angle, and the second side surface 5204 and the first bottom surface 5205 are connected at an included angle. The first top surface 5202 faces the first bottom surface 5205, and the first arc-shaped convex surface 5201, the second arc-shaped convex surface 5203, and the first top surface 5202 are arcs with different curvatures. In this embodiment, the first arc-shaped convex surface 5201 and the second arc-shaped convex surface 5203 are arcs (ensuring that the arc fits the shape of the concave curved surface 5124a of the limiting block) and have the same curvature. It can be seen that the second shielding body 520 has a symmetrical structure. The second arc-shaped convex surface 5203 of the second shielding body cooperates with the first end surface of the first sub-bezel 221, and the first arc-shaped convex surface 5201 cooperates with the limiting block 5124.

[0081] Refer to FIG. 6C. In the present application, the third shielding body 530 is shown as a sector-shaped block body, and includes a third side surface 5300, a third arc-shaped convex surface 5301, a second top surface 5302, a fourth arc-shaped convex surface 5303, a fourth side surface 5304, a second bottom surface 5305, a third surface 5306, and a fourth surface 5307. It can be understood that the third shielding body 530 includes two arc-shaped convex surfaces arranged opposite to each other, and the two arc-shaped convex surfaces include the third arc-shaped convex surface 5301 and the fourth arc-shaped convex surface 5303. The third surface 5306 and the fourth surface 5307 face opposite to each other. In the present application, the structure of the third shielding body 530 is shown as a sector with the third surface 5306 and the fourth surface 5307. It should be understood that the third surface 5306 and the fourth surface 5307 include, but are not limited to, shapes such as a sector, an ellipse, or a rectangle. The third side surface 5300, the third arc-shaped convex surface 5301, the second upper surface 5302, the fourth arc-shaped convex surface 5303, the fourth side surface 5304, and the second bottom surface 5305 are successively joined. The third side surface 5300, the third arc-shaped convex surface 5301, the second upper surface 5302, the fourth arc-shaped convex surface 5303, and the fourth side surface 5304 are successively joined smoothly. The third side surface 5300 and the second bottom surface 5305 are joined at an included angle, and the fourth side surface 5304 and the second bottom surface 5305 are joined at an included angle. The second upper surface 5302 faces the second bottom surface 5305, and the third arc-shaped convex surface 5301, the second upper surface 5302, and the fourth arc-shaped convex surface 5303 are arcs having different curvatures. In this embodiment, the third arc-shaped convex surface 5301 and the fourth arc-shaped convex surface 5303 are arcs (ensuring that the arc fits the shape of the concave curved surface 5124 of the limiting block) and have the same curvature. It can be seen that the third shield 530 is a symmetrical structure. The fourth arc-shaped convex surface 5303 of the third shield cooperates with the second end surface of the third sub-bezel 321, and the third arc-shaped convex surface 5301 cooperates with the limiting block 5124 away from the second shield.

[0082] In a possible implementation, the first shield 510, the second shield 520 and the third shield 530 are made of metal materials. In a usage scenario, such as a high temperature or long-term bending scenario, the metal materials can avoid deformation that is difficult to recover, ensure the aesthetic appearance of the folding electronic device, and improve the product competitiveness.

[0083] Please refer to Figures 7 and 8. Figure 7 is a schematic diagram of a side structure of a foldable electronic device 1000 in an unfolded state according to an embodiment of the present application. Figure 8 is a schematic diagram of an outer side structure of a foldable electronic device 1000 in an unfolded state according to an embodiment of the present application.

[0084] The foldable electronic device 1000 is in an unfolded state. The two shielding members 500 are symmetrical. Taking one shielding member 500 as an example, the assembly relationship between the shielding member 500 and the central shaft assembly 400 will be described.

[0085] The central shaft assembly 400 is mounted between the first housing 200 and the second housing 300, and the shielding member 500 is located between the first sub-bezel 221 and the third sub-bezel 321 (i.e., between the first housing 200 and the second housing 300). As shown in FIG. 2 and FIG. 3, the limiting block 5124 of the first shielding body 510 faces the second end 412 of the base 410, and the first coupling surface 5122 of the limiting body 512 is fastened to the surface of the second end 412. The second surface 5207 of the second shielding body 520 faces the fourth end 422 of the first rotating part 420 and may be fastened to the end surface of the fourth end 422. The fourth surface 5307 of the third shielding body 530 faces the sixth end 432 of the second rotating part 430 and may be fastened to the end surface of the sixth end 432.

[0086] The second shielding body 520, the first shielding body 510, and the third shielding body 530 are sequentially arranged in the width direction (Y-axis direction), and a part of the second shielding body 520 and a part of the third shielding body 530 are stacked on the first shielding body 510. The second shielding body 520 is arranged facing and spaced apart from the limiting body 512, and there is a rotation gap between the first arc-shaped convex surface 5201 and the concave curved surface 5124a of the limiting block 5124. The third shielding body 530 is arranged facing and spaced apart from the other side of the limiting body 512, and there is a rotation gap between the third arc-shaped convex surface 5301 and the concave curved surface 5124a of the limiting block 5124. When the shielding member 500 is subjected to an impact, there is an overlap between the second shielding body 520 and the first shielding body 510, and between the first shielding body 510 and the third shielding body 530, and the first housing 200, the second shielding body 520, the first shielding body 510, the third shielding body 530 and the second housing 300 sequentially limit each other.

[0087] The main shielding exterior surface 5110 of the first shielding body 510 and the outer surface of the first sub-bezel 221 may face the same direction and be on the same plane. Specifically, the main shielding exterior surface 5110 and the outer surface of the first exterior body 2211 face the same direction. The main shielding exterior surface 5110 of the first shielding body 510 and the outer surface of the third sub-bezel 321 may face the same direction and be on the same plane. Specifically, the main shielding exterior surface 5110 and the outer surface of the second exterior body 3211 face the same direction. The first surface 5206 of the second shielding body 520 is located in the gap between the first shielding body 510 and the first sub-bezel 221. The third surface 5306 of the third shielding body 530 is located in the gap between the first shielding body 510 and the third sub-bezel 321. The second shield 520, the first shield 510 and the third shield 530 are coupled together to the first and second housings to shield the central shaft assembly 400. The first shield 510, the second shield 520 and the third shield 530 jointly form the exterior surface of the exterior surface structure. That is, the main shield exterior surface 5110 of the first shield 510, the first surface 5206 of the second shield 520, the third surface 5306 of the third shield 530, the outer surface of the first bezel 220 and the outer surface of the second bezel 320 function together as the outer end surfaces of both ends of the main body, i.e., the exterior surfaces.

[0088] The exterior surface of the exterior structure faces the same direction as the exterior surfaces of the first housing 200 and the second housing 300, and the exterior surfaces of the second shielding body 520 and the third shielding body 530 are located in the gap between the first shielding body 510 and the first housing 200 and the gap between the first shielding body 510 and the second housing 300, respectively. When the foldable electronic device 1000 is in a folded state, the first housing 200 and the second housing 300 are folded facing each other via the central shaft assembly 400, and the second shielding body 520 and the third shielding body 530 rotate separately by a specific angle with respect to the first shielding body 510 as the central shaft assembly 400 rotates.

[0089] The sides of the first sub-bezel 221, the second shielding body 520, the first shielding body 510, the third shielding body 530 and the third sub-bezel 321 jointly form one side of the exterior surface of the folding electronic device 1000. The first shielding body 510, the second shielding body 520 and the third shielding body 530 jointly cover the gap between the first sub-bezel 221 and the third sub-bezel 321. Specifically, the second shielding body 520 has a portion overlapping both the first shielding body 510 and the first exterior body 2211 of the first sub-bezel 221, and the first sub-bezel 221, the second shielding body 520 and the first shielding body 510 are stacked in sequence, and there is no gap in the Y direction. The third shielding body 530, like the second shielding body 520, has a portion overlapping with both the second outer body 3211 of the third sub-bezel 321 and the first shielding body 510, and there is no gap in the Y direction between the third sub-bezel 321 and the third shielding body 530 and between the third shielding body 530 and the first shielding body 510. In the unfolded or folded state of the foldable electronic device 1000, there is no gap between the second shielding body 520 and the first shielding body 510 and between the first shielding body 510 and the third shielding body 530, and there is no gap between the second shielding body 520, the first shielding body 510, and the third shielding body 530 and both the first housing 200 and the second housing 300. Therefore, it can be seen that the central shaft assembly and internal components of the foldable electronic device 1000 are shielded, thereby protecting and concealing the internal components. Therefore, the appearance of the foldable electronic device 1000 is more concise and beautiful.

[0090] Specifically, the second shield 520 includes two arc-shaped convex surfaces arranged opposite to each other, that is, a first arc-shaped convex surface 5201 and a second arc-shaped convex surface 5203. The third shield 530 includes two arc-shaped convex surfaces arranged opposite to each other, that is, a third arc-shaped convex surface 5301 and a fourth arc-shaped convex surface 5303. One of the arc-shaped convex surfaces of the second shield 520 and one of the arc-shaped convex surfaces of the third shield are each arranged opposite to two concave curved surfaces 5124a. That is, the first arc-shaped convex surface 5201 of the second shield 520 faces the concave curved surface 5124a of the limiting body 512 and is spaced apart from it to have a rotation gap, and the third arc-shaped convex surface 5301 of the third shield 530 faces the other concave curved surface 5124a of the limiting body 512 of the first shield 510 and is spaced apart from it to have a rotation gap. The other arc-shaped convex surface of the second shielding body 520 and the other arc-shaped convex surface of the third shielding body 530 are capable of sliding and rotating relative to the end surface of the first housing 200 and the end surface of the second housing 300, respectively. That is, the second arc-shaped convex surface 5203 of the second shielding body 520 faces the first end surface 2210 with a gap therebetween, the first surface 5206 of the second shielding body 520 faces the first inner side surface 2211a of the first sub-bezel 221, and the first end surface 2210 of the first sub-bezel 221 faces the second arc-shaped convex surface 5203 with a gap therebetween.

[0091] The deployed state of the third shielding body 530 is similar to that of the second shielding body 520. The fourth arc-shaped convex surface 5303 of the third shielding body 530 faces the second end surface 3210 with a gap therebetween, the third surface 5306 of the third shielding body 530 faces the second inner surface 3211a of the third sub-bezel 321, and the second end surface 3210 of the third sub-bezel 321 faces the fourth arc-shaped convex surface 5303 with a gap therebetween.

[0092] The first shielding body 510 is fastened to the base 410, and the first housing 200, the second shielding body 520, the first shielding body 510, the third shielding body 530, and the second housing 300 sequentially restrict one another and cooperate to maintain stability, thereby restricting the position of the shielding member 500. In addition, the central shaft assembly 400 realizes the flattened state and positioning of the first housing 200 and the second housing 300, restricts the relative positions of the second shielding body 520, the first shielding body 510, and the third shielding body 530 in the Y-axis direction, and restricts the relative positions of the second shielding body 520, the first shielding body 510, and the third shielding body 530 to the first housing 200 and the second housing 300 in the Y-axis direction. That is, when the first housing 200 and the second housing 300 are flattened together, the spread angle of the second shielding body 520, the first shielding body 510 and the third shielding body 530 is determined via the central shaft assembly.

[0093] When the foldable electronic device 1000 is subjected to an external force, the first sub-bezel 221, the second shield 520, the first shield 510, the third shield 530, and the third sub-bezel 321 are sequentially abutted against each other, thereby reducing the displacement of the positional deviation of each component. The first shield 510 has an overlapping position with the second shield 520 and the third shield 530, and the overlapping position of the first shield 510 and the second shield 520 and the overlapping position of the first shield 510 and the third shield 530 can strengthen the mechanical strength of the exterior housing of the foldable electronic device 1000 in this part of the central shaft assembly 400, thereby avoiding damage to the foldable electronic device 1000 caused by insufficient strength of the joint between the first shield 510 and the second shield 520 and the joint between the first shield 510 and the third shield 530. The mid-frame assembly of the foldable electronic device 1000 provides a seamless all-metal appearance effect, improving the aesthetics of the foldable electronic device 1000.

[0094] In a possible embodiment, the first shield 510 may be coupled to both ends of the base 410. The second shield 520 is not directly coupled to the first rotating part 420, and the third shield 530 is not directly coupled to the second rotating part 430, and only the positions are mutually limited. The first shield 510, the first mounting groove, and the first sub-bezel 221 may together limit the second shield 520, and the first shield 510, the second mounting groove, and the third sub-bezel 321 may together limit the third shield 530.

[0095] When the central shaft assembly 400 receives an impact, the gap between the first shield 510 and the second shield 520 and the gap between the first shield 510 and the third shield 530 are small, and the external force is buffered. When the end of the central shaft assembly 400 receives an impact due to an external force, the first shield 510 can receive the main impact load. The second shield 520 and the third shield 530 partially overlap the first shield 510 and do not directly receive the impact load, so the second shield 520 transfers the impact load of the first shield 510 to the first sub-bezel 221, and the third shield 530 transfers the impact load of the first shield 510 to the third sub-bezel 321. The impact load received by the first shield 510 is decomposed into the second shield 520 and the third shield 530, and buffers the external force of the first shield 510. In addition, the positions of the base 410 and the first rotating part 420 are restricted relative to each other, and the positions of the base 410 and the second rotating part 430 are restricted relative to each other, thereby reducing the displacement of the positional deviation of the base 410, the first rotating part 420, and the second rotating part 430 that are subjected to the impact of an external force, reducing the deformation of the display, and increasing the mechanical strength of the foldable electronic device 1000. Similarly, when the second shielding body 520 or the third shielding body 530 is subjected to the impact of an external force, a part of the energy of the impact can be transmitted to the first shielding body 510 to disperse the impact force, and the display 100 can be effectively protected. When the foldable electronic device 1000 is dropped in the unfolded state, the first housing 200 or the second housing 300 is first impacted, and the impact force may be transmitted from the first sub-bezel 221 to the second shielding body 520 adjacent to the first sub-bezel 221. Alternatively, the third sub-bezel 321 transmits the impact force to the third shield 530, and the second shield 520 and the third shield 530 transmit a portion of the impact force again to the first shield 510 to disperse the impact force and protect the display 100.

[0096] Please refer to Figure 9. Figure 9 is a schematic diagram of the side structure of the foldable electronic device 1000 in a folded state according to an embodiment of the present application. In the folded state of the foldable electronic device 1000, the first end surface 2210 has a gap facing the second side surface 5204, a part of the first surface 5206 has a gap facing the first inner surface 2211a, the first side surface 5200 has a gap facing the sliding surface 5121, a part of the first surface 5206 faces the coupling surface 5111 of the main shield 511, and the first arc-shaped convex surface 5201 has a rotation gap facing the concave curved surface 5124a. The concave curved surface 5124a of the other limiting block 5124 faces the third arc-shaped convex surface 5301 and has a rotation gap, the other sliding surface 5121 faces the third side surface 5300 and has a gap, a part of the third surface 5306 faces the coupling surface 5111 of a part of the main shielding body 511, the fourth side surface 5304 faces the second end surface 3210 and has a gap, and a part of the third surface 5306 faces the second inner side surface 3211a and is spaced apart. Since the first shielding body 510, the second shielding body 520, the third shielding body 530, and the first sub-bezel 221 and the second sub-bezel 222 are arranged opposite to each other and limit each other, it can be seen that the positions of the first housing 200, the second shielding body 520, the first shielding body 510, the third shielding body 530, and the second housing 300 do not shift significantly. Therefore, a stable bending state is maintained, and damage to the display 100 caused by bending the display 100 at a bending angle greater than a preset bending angle can be avoided.

[0097] When the foldable electronic device 1000 receives an impact in a folded state, the first housing 200, the second shield 520, the first shield 510, the third shield 530, and the second housing 300 contact each other in sequence to limit each other, dispersing the impact load. That is, when the foldable electronic device 1000 receives an impact in a folded state, the first end surface 2210 and the second side surface 5204 can abut each other, and the first housing 200 and the second shield 520 limit each other in sequence. The first side surface 5200 and one sliding surface 5121 contact each other for limiting, and the third side surface 5300 and the other sliding surface 5121 contact each other for limiting, and therefore the second shield 520, the first shield 510, and the third shield 530 abut each other in sequence for limiting. The fourth side surface 5304 and the second end surface 3210 are in contact with each other for limiting purposes, and therefore the third shield 530 and the second housing 300 can abut against each other for limiting purposes.

[0098] In addition, when the foldable electronic device 1000 is in a folded state and an end of the folding part is impacted with a force in a specific direction, the gaps between the first housing 200, the second shield 520, the first shield 510, the third shield 530, and the second housing 300 can sequentially provide a buffer space. In addition, the first housing 200, the second shield 520, the first shield 510, the third shield 530, and the second housing 300 may sequentially abut against each other to distribute the impact load and protect the structure of the foldable electronic device 1000.

[0099] For example, when the foldable electronic device 1000 is folded, the side surfaces of the third surface 5114 of the first shielding body 510, the first top surface 5202 of the second shielding body 520, and the second top surface 5302 of the third shielding body 530 may form an arc shape together. The arc shape can make the appearance of the first shielding body 510, the second shielding body 520, and the third shielding body 530 more simple, and can match the angle of the first housing 200 and the second housing 300 after the first housing 200 and the second housing 300 rotate via the central shaft assembly 400. In addition, when the foldable electronic device 1000 is in a folded state, the angular positioning provided by the first shielding body 510, the second shielding body 520, and the third shielding body 530, and the angular restriction provided to the first housing 200 and the second housing 300 by the second shielding body 520 and the third shielding body 530 are performed via the central shaft assembly 400. In other words, when the angular positioning of the first housing 200 and the second housing 300 is performed via the central shaft assembly 400, the angles of the first shielding body 510, the second shielding body 520, and the third shielding body 530 are also positioned, and the stability of the shielding member 500 is ensured.

[0100] Please refer to Fig. 10. Fig. 10 is a schematic diagram of another example of the structure of the foldable electronic device 1000 according to an embodiment of the present application. When the foldable electronic device 1000 is in an unfolded state, the first housing 200 and the second housing 300 are flattened against each other, and the first housing 200, the second shielding body 520, the first shielding body 510, the third shielding body 530, and the second housing 300 are sequentially arranged in a first direction, and the first shielding body 510, the second shielding body 520, and the third shielding body 530 jointly cover the space between the first sub-bezel 221 and the third sub-bezel 321. Specifically, the second shielding body 520 has a portion overlapping with both the first shielding body 510 and the first appearance body 2211 of the first sub-bezel 221, and there is no gap in the Y direction between the first sub-bezel 221 and the second shielding body 520, and between the second shielding body 520 and the first shielding body 510. The third shielding body 530, like the second shielding body 520, has a portion overlapping with both the second appearance body 3211 and the first shielding body 510 of the third sub-bezel 321, and there is no gap in the Y direction between the third sub-bezel 321 and the third shielding body 530, and between the third shielding body 530 and the first shielding body 510, thereby shielding the internal components, protecting the internal components, and hiding the internal components, making the appearance more simple and beautiful.

[0101] Please refer to Fig. 11. Fig. 11 is a schematic exploded view of the foldable electronic device 1000 of Fig. 10 in an unfolded state. The first shield 510 is rotatably coupled to the second shield 520 and the third shield 530 separately via a rotating shaft, and both the second shield 520 and the third shield 530 are rotatably coupled to the first housing 200 and the second housing 300 separately via a rotating shaft. Since the second shield 520 is separately coupled to the first shield 510 and the first housing 200 via a rotating shaft, the coupling manner is stable, ensuring that the second shield 520 rotates more efficiently and stably. Since the third shield 530 is separately coupled to the first shield 510 and the second housing 300 via a cylinder, the coupling force between the third shield 530 and the first shield 510 and the coupling force between the end of the third shield 530 and the second housing 300 can be increased. In the event of an impact, displacement is unlikely to occur, and damage to other structures of the foldable electronic device 1000 can be avoided as much as possible.

[0102] Specifically, the main shield 511 has a first rotation axis 511a and a second rotation axis 511b, and the axial directions of the first rotation axis 511a and the second rotation axis 511b may be perpendicular or substantially perpendicular to the main shield 511. The first rotation axis 511a and the second rotation axis 511b are arranged in a convex shape on the coupling surface 5111 of the first shield 510, and the axes of the first rotation axis 511a and the second rotation axis 511b may be perpendicular to the coupling surface 5111. One concave curved surface 5124a faces the first rotation axis 511a, and the other concave curved surface 5124a faces the second rotation axis 511b.

[0103] The second shielding body 520 is provided with a first through hole 520a and a second through hole 520b. The first through hole 520a and the second through hole 520b penetrate the first surface 5206 and the second surface 5207. Each first exterior body 2211 includes a third rotation shaft 2211b. The third rotation shaft 2211b is arranged in a convex shape on the first inner surface 2211a of the first exterior body 2211. The axis direction of the third rotation shaft 2211b may be perpendicular to the first inner surface 2211a. The third shielding body 530 includes a third through hole 530a and a fourth through hole 530b. The third through hole 530a and the fourth through hole 530b penetrate the third surface 5306 and the fourth surface 5307. Each second exterior body 3211 includes a fourth rotation shaft 3211b. The fourth rotation shaft 3211b is disposed in a convex shape on the second inner side surface 3211a of the second exterior body 3211. The axis direction of the fourth rotation shaft 3211b may be perpendicular to the second inner side surface 3211a. The first through hole 520a of the second shielding body 520 is coupled to the first rotation shaft 511a, and the second through hole 520b of the second shielding body 520 is coupled to the third rotation shaft 2211b. The third through hole 530a of the third shielding body 520 is coupled to the second rotation shaft 511b, and the fourth through hole 530b is coupled to the fourth rotation shaft 3211b. When the foldable electronic device 1000 is folded or unfolded, the first rotating shaft 511a can rotate within the first through hole 520a, the second rotating shaft 511b can rotate within the third through hole 530a, the third rotating shaft 2211b can rotate within the second through hole 520b, and the fourth rotating shaft 3211b can rotate within the fourth through hole 530b.

[0104] The first shielding body 510 may further include a first fastener 511c and a second fastener 511d. After assembly, a part of the second shielding body 520 is stacked with the first shielding body 510, a part of the second shielding body 520 is stacked with the first exterior body 2211, the first rotating shaft 511a passes through the first through hole 520a, and the first fastener 511c is coupled to the end of the first rotating shaft 511a, that is, located on the second surface 5207. The second shielding body 520 is located between the coupling surface 5111 and the first fastener 511c. The first rotating shaft 511a passes through the first through hole 520a and is locked via the first fastener 511c. That is, the second shielding body 520 is separately rotatably coupled to the first shielding body 510 and the first sub-bezel 221. The first fastener 511c allows the second shield 520 to rotate using only the axial direction of the first rotating shaft 511a as a central axis, and reduces sliding of the second shield 520 in the axial direction of the first rotating shaft 511a. The second fastener 511d is coupled to one end of the second rotating shaft 511b, and the third shield 530 is disposed between the coupling surface 5111 and the second fastener 511d. The second fastener 511d allows the third shield 530 to rotate using only the axial direction of the second rotating shaft 511b as a central axis, and reduces sliding of the third shield 530 in the axial direction of the second rotating shaft 511b.

[0105] The first exterior body 2211 may include a third fastener 2211c. After assembly, the third fastener 2211c is coupled to one end of the third rotating shaft 2211b, the third fastener 2211c is located on the second surface 5207, and the second shielding body 520 is disposed between the first inner surface 2211a and the third fastener 2211c. The third rotating shaft 2211b penetrates the second through-hole 520b and is engaged via the third fastener 2211c. The third fastener 2211c allows the second shielding body 520 to rotate using only the axial direction of the third rotating shaft 2211b as a central axis, and reduces sliding of the second shielding body 520 in the axial direction of the third rotating shaft 2211b.

[0106] The second exterior body 3211 may include a fourth fastener 3211c. After assembly, the fourth fastener 2211c is coupled to one end of the fourth rotating shaft 3211b, the fourth fastener is located on the fourth surface 5307, and the third shielding body 530 is disposed between the second inner surface 3211a and the fourth fastener 2211c. The fourth rotating shaft 3211b passes through the fourth through hole 530b and is engaged via the fourth fastener 3211c. The fourth fastener 3211c allows the third shielding body 530 to rotate using only the axial direction of the fourth rotating shaft 3211b as a central axis, and reduces sliding of the third shielding body 530 in the axial direction of the fourth rotating shaft 3211b.

[0107] Please refer to Fig. 12. Fig. 12 is a schematic enlarged view of a partial structure of the foldable electronic device 1000 of Fig. 10 in an unfolded state. The first shielding body 510 is directly coupled to the second shielding body 520 through the first rotating shaft 511a, and directly coupled to the third shielding body 530 through the second rotating shaft 511b. The first outer body 2211 is directly coupled to the second shielding body 520 through the third rotating shaft 2211b, and the second outer body 3211 is directly coupled to the third shielding body 530 through the fourth rotating shaft 3211b. Since the second shielding body 520 is separately coupled to the first shielding body 510 and the first outer body 2211 through a cylinder, the coupling state is stable, thereby ensuring that the second shielding body 520 rotates more efficiently and stably. Since the third shielding body 530 is separately coupled to the first shielding body 510 and the second exterior body 3211 via cylinders, it is possible to increase the coupling strength between the third shielding body 530 and the first shielding body 510 and the coupling strength between the third shielding body 530 and the third sub-bezel 321. When an impact occurs, displacement is unlikely to occur, and damage to the display 100 can be avoided as much as possible.

[0108] In this embodiment, the first shielding body 510 is directly connected to the base 410, the second shielding body 520 is not connected to the first rotating part 420, and the third shielding body 530 is not connected to the second rotating part 430. During assembly, the central shaft assembly 400 is fastened to the first housing 200 and the second housing 300, and then the second shielding body 520 and the third shielding body 530 are assembled. That is, after the through holes of the second shielding body 520 and the third shielding body 530 are connected to a cylinder, the end of the cylinder is restricted using a fastener to prevent the second shielding body 520 and the third shielding body 530 from falling off. Since the second shielding body 520 is not directly connected to the first rotating part 420, the movements of the second shielding body 520 and the first rotating part 420 do not affect each other. When the second shield 520 is impacted by an external force, the movement function of the first rotating part 420 is not affected, so the impact of the first rotating part 420 on the display 100 is reduced, and the display 100 is protected. The coupling relationship between the third shield 530 and the first rotating part 420 is similar to that between the second shield 520 and the first rotating part 420, and therefore will not be described again here. The first shield 510, the second shield 520, the third shield 530, the first housing 200, and the second housing 300 together form an enclosure frame, which can protect the inside of the foldable electronic device 1000. In addition, even if the foldable electronic device 1000 is dropped, the movement function of the central shaft assembly 400 is protected and the abnormal function of the central shaft assembly 400 is reduced, so that the drop reliability of the display 100 is improved. Any abnormal action, such as displacement of the base 410, the first rotating part 420 or the second rotating part 430, may cause damage to the display 100.

[0109] The above describes the embodiments of the present application in detail. The principles and implementations of the present application are described herein through specific examples. The description of the embodiments of the present application is provided merely to help understand the method and core ideas of the present application. Furthermore, those skilled in the art can make modifications and changes to the present application in terms of specific implementations and the scope of the present application based on the ideas of the present application. Therefore, the contents of the specification should not be considered as limitations on the present application.
