Description

[Technical Field]

[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, and in particular to foldable electronic devices. [Background technology]

[0003] Foldable electronic devices are becoming increasingly popular in the market. Take foldable smartphones, which feature a flexible and foldable screen, as an example. After folding, the screen size is similar to that of a typical smartphone, making foldable smartphones easy to carry and use. After unfolding, the screen size is similar to that of a tablet computer, making it convenient to use entertainment and office functions on the unfolded screen. Foldable smartphones combine the advantages of electronic devices and tablet computers and meet the needs of current consumers. However, foldable screens are prone to damage due to their large surface area and frequent folding movements. Therefore, protecting the screen is very important. The most vulnerable area of ​​a foldable electronic device is the edge of the folding portion of the screen. Therefore, how to effectively increase the strength of the edge of the folding portion is an unavoidable issue for foldable electronic devices. 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 opposite sides of the central shaft assembly, and the central shaft assembly rotates the first housing and the second housing relative to each other. Each shielding member includes a first shield, a second shield, and a third shield. The second shield and the third shield are located on opposite sides of the first shield, and both the second shield and the third shield are rotatable relative to the first shield. In a second direction, the second shield is disposed on the side of the first shield facing the central shaft assembly and partially stacked with the first shield, and the third shield is disposed on the side of the first shield facing the central shaft assembly and partially stacked with the first shield.

[0006] In the second direction, the two shielding members are respectively 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 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, second, and third shields jointly form part of the exterior structure of the foldable electronic device. 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. Therefore, impact loads on the first shield are distributed to the two sides of the first and second housings, protecting the internal components. This reduces the possibility of misalignment between the first, second, and third shields, improving the structural stability of the foldable electronic device. Furthermore, the first, second, and third shields shield the internal components in the space where the central shaft assembly is located, improving the appearance of the foldable electronic device. The shielding members are respectively disposed at the two ends of the central shaft assembly, further providing a uniform shielding effect to the two ends of the central shaft assembly and further simplifying the appearance of the foldable electronic device.

[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 portion of the second housing. The exterior surfaces of the second shield and the third shield are located in the gap between the first shield and the first housing and the 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 together, 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 when the foldable electronic device is in an unfolded state, the first, second, and third shields cover the gap between the first and second housings, and the end faces of the foldable electronic device in the unfolded state at the folded position are covered by the shielding members, thereby protecting the internal components and simplifying the external structure of the foldable electronic device. When the foldable electronic device is in a folded state, the first, second, and third shields rotate relative to each other as the central shaft assembly rotates, completely covering and protecting the end faces of the folded central shaft, and can bend at an angle as the first and second housings are folded toward each other.

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

[0012] It can be seen that there is a rotation gap between one side of the second shield and the limiting member of the first shield, and the other side of the second shield is spaced apart and facing the edge of the first housing. There is a rotation gap between one side of the third shield and the limiting member of the first shield, and the other side of the third shield is spaced apart and facing the edge 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. The first housing, second shield, first shield, third shield, and second housing can rotate relative to and limit each other in sequence. This makes the structure of the foldable electronic device stable and less susceptible to damage during use.

[0013] In one possible implementation, 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 apart from and opposite an end face of the first housing, and the other of the arcuate convex surfaces of the third shielding body is spaced apart from and opposite an end face of the second housing. When an external force acts on the end of the electronic device, there are overlapping portions between the second shield and the first shield, and between the first shield and the third shield, and the first housing, the second shield, the first shield, the third shield, and the second housing abut against each other in sequence, restricting each other in sequence, thereby cushioning and reducing the impact force against each other and avoiding the impact on the lifespan of the electronic device due to damage to the shielding member.

[0014] It can be seen that the concave curved surface is arranged to cooperate with the arc-shaped convex surface, which makes the rotation between the limiting body and the second or third shield smoother and more stable, thereby ensuring the reliability of the folding and unfolding processes of the foldable electronic device. The concave curved surface can further limit the arc-shaped convex surface at multiple angles, which can improve the stability of the relative movement between the first and second shields 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] The second shield is connected to the first shield and the first housing separately via a rotation shaft, which stabilizes the connection and allows the second shield to rotate more efficiently and stably. The third shield is connected to the first shield and the second housing separately via a cylinder, which increases the connection strength between the third shield and the first shield and between the end of the second housing. In the event of an impact, displacement is unlikely to occur, and damage to other structures of the foldable 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, ensuring the aesthetic appearance of foldable electronic devices and improving product competitiveness.

[0019] In a possible implementation, the limiting body has an arc-shaped end surface and two sliding surfaces arranged opposite each other, each sliding surface being coupled to one end of the arc-shaped end surface, the limiting block being located close to the arc-shaped 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 connection between the concave curved surface and the sliding surface can simplify the movement of the second and third shields. The second and third shields can each rotate under the constraint of the concave curved surface. When the foldable electronic device is in the folded state, the sliding surface can abut against one side of the second or third shield.

[0021] In one possible implementation, the first housing includes a first sub-bezel and a second sub-bezel arranged opposite each other. The first sub-bezel has a first end surface and a first appearance body arranged convexly on the first end surface, and the second sub-bezel has a second end surface and a second appearance body arranged convexly on the second end surface. In the first direction, the first shield is located between the first appearance body and the second appearance body. The second shield is partially stacked on the first appearance body, and the arc-shaped convex surface of the second shield is spaced apart from and faces the first end surface. The third shield is partially stacked on the third appearance body, and the arc-shaped convex surface of the third shield is spaced apart from and faces 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. When the foldable electronic device is in an unfolded or folded state, the first sub-bezel, the second shielding member, the first shielding member, the third shielding member, and several side surfaces 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 surface and a second side surface arranged opposite each other, and the third shield further includes a third side surface and a fourth side surface arranged opposite each other. When the foldable electronic device is in a folded state, the first side surface is spaced apart opposite one sliding surface, the second side surface is spaced apart opposite the first end surface, the third side surface is spaced apart opposite the other sliding surface, and the fourth side surface is spaced apart opposite 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 constrained 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 to each other and all coupled to the first surface and the second surface. The first surface is positioned opposite the second surface, and the first side surface and the second side surface are separately positioned at an angle relative 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 connected to form a third surface and a fourth surface. The third surface and the fourth surface are arranged opposite each other. The third side surface and the fourth side surface are separately arranged at an angle to the second bottom surface, and the third surface is the exterior surface of the third shielding body.

[0026] When the foldable electronic device is in a folded state, the first top surface, the arcuate end surface of the first shielding member, and the fifth arcuate surface can be integrally formed into an arc shape. The arc shape can simplify the appearance of the first shield, the second shield, and the third shield and is compatible with the angles obtained after the first housing and the second housing are separately rotated via the central shaft assembly. When the foldable electronic device is in a folded state, 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, simplifying the overall structure when the foldable electronic device is in an unfolded state.

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

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

[0029] When the foldable electronic device is in a folded state, 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 surfaces of the first and second housings that carry the displays face each other. After folding, the displays are located inside the main body structure. Alternatively, the surfaces of the first and second housings that carry the displays face away from each other. After folding, the displays are located outside the structure. In other words, the foldable electronic device may be an inside-foldable screen electronic device or an outside-foldable screen electronic device. The first shield, the second shield, and the third shield can collectively form part of the exterior structure of the foldable electronic device. The second and third shields are partially stacked on the first shield, i.e., have overlapping portions, and are not directly subjected to impact loads, so that the impact load on the first shield is resolved to the first and second housings on the two sides, thereby protecting the display from impacts.

[0031] In one possible implementation, the central shaft assembly includes a base, a first rotating portion, and a second rotating portion. The base includes a first end and a second end, the first rotating portion includes a third end and a fourth end, and the second rotating portion 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 should be understood 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 unit, and the third shield may not be coupled to the second rotating unit; only their positions are mutually constrained. When the central shaft assembly is subjected to an impact, 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 constrain each other to buffer the external force. When the central shaft assembly is subjected to an external force, the first shield may bear the main impact load, while the second shield and the third shield may buffer the external force against the first shield without directly receiving the impact load. Furthermore, by constraining the positions of the base and the first rotating unit and the base and the second rotating unit, it is possible to reduce misalignment of the base, the first rotating unit, and the second rotating unit when subjected to an external force, thereby reducing deformation of the display and improving the mechanical strength of the foldable electronic device. Similarly, when the second or third shield receives an external force, a portion of the impact energy is transferred to the first shield, dispersing the impact force and reducing misalignment among the first, second, and third shields and the central shaft assembly, thereby effectively protecting the display. When a foldable electronic device is dropped in an unfolded state, the first or second housing may receive the impact first, and the impact force may then 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 portion of the impact force back to the first shield, thereby dispersing the impact force and reducing misalignment among the first, second, and third shields and the central shaft assembly, thereby effectively protecting the display. Because the second shield is not directly coupled to the first rotating unit, the movements of the second shield and the first rotating unit do not affect each other. When the second shield is subjected to 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 illustrate 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 used in the embodiments of the present application will be explained first.

[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.

[0052] Foldable electronic devices are becoming increasingly popular in the market. Take foldable smartphones, which feature flexible and foldable screens, as an example. After folding, the screen size is similar to that of a typical smartphone, making foldable smartphones easy to carry and use. After unfolding, the screen size can be similar to that of a tablet computer, making it convenient to use entertainment and office functions on the unfolded screen. Foldable smartphones combine the advantages of electronic devices and tablet computers and meet the needs of current consumers. However, foldable screens are prone to damage due to their large surface area and frequent folding movements. Therefore, protecting the screen is very important. The most vulnerable area of ​​a foldable electronic device is the edge of the screen at the bend. Therefore, how to effectively increase the strength of the screen edge at the bend becomes an unavoidable issue for foldable electronic devices.

[0053] In view of this, the present application provides a foldable electronic device that effectively increases the strength of the end of the folding part 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 the display 100 and the main body of the foldable electronic device 1000 according to an embodiment of the present application. Figure 3 is a schematic exploded view of the 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 this embodiment of the present application, an example will be described in which the foldable electronic device 1000 is a smartphone.

[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 away from 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, Y direction, and Z direction are perpendicular to each other.

[0058] The foldable electronic device 1000 includes a display 100 and a main body (not shown). The display 100 is mounted on the main body. The display includes a display surface and a mounting surface, which are arranged opposite each other. The display surface is configured to display text, images, video, 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 is flexible and bendable 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 (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 a first portion 110 and a 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 toward 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 opposite directions 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 each coupled to either side of the central shaft assembly 400, and the central shaft assembly 400 rotates the first housing 200 and the second housing 300 relative to each other. Each shielding member 500 includes a first shielding body 510, a second shielding body 520, and a third shielding body 530, and the second shielding body 520 and the third shielding body 530 are located on either side of the first shielding body 510, and both the second shielding body 520 and the third shielding body 530 are 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 respectively 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 part of the exterior structure of the foldable electronic device 1000. The first direction is perpendicular to the second direction.

[0062] The exterior surfaces of the first shield 510, the second shield 520, and the third shield 530 collectively 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 a portion of the second housing 300, and the exterior surfaces of the second shield 520 and the third shield 530 are respectively located in the gap between the first shield 510 and the first housing 200 and the gap between the first shield 510 and the second housing 300. When the foldable electronic device 1000 is in the unfolded state, the first housing 200 and the second housing 300 are flattened against each other, and the first housing 200, the second shield 520, the first shield 510, the third shield 530, and the second housing 300 are sequentially arranged in a first direction. When the foldable electronic device 1000 is in a folded state, the first housing 200 and the second housing 300 are folded to face each other, and the second shield 520 and the third shield 530 are rotated separately by a specific angle relative to the first shield 510.

[0063] Note that FIG. 2 merely illustrates one example of the 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, 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 illustrated in the figure may be implemented by hardware, software, or a combination of software and hardware.

[0064] Although electronic devices with large screens may be more convenient for everyday use, they are inconvenient to carry around. The emergence of foldable electronic devices solves this problem. When the foldable electronic device 1000 is unfolded, its screen size can be made larger than that of a typical electronic device, enabling the foldable electronic device 1000 to have large-screen display and operation functions, thereby improving the user experience when watching videos or engaging in entertainment. When a user does not need a large screen, the foldable electronic device 1000 can be folded. When the foldable electronic device 1000 is folded, the display 100 of the foldable electronic device 1000 with the screen facing outward 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, significantly reducing the probability of damage to the display 100. Furthermore, the overall size is small, making the foldable electronic device easy to carry.

[0065] Further, refer to Fig. 3. A first mounting groove (not shown) is provided in the first housing 200, and a second mounting groove (not shown) is provided in the second housing, 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 coupled. The first housing 200 and the second housing 300 rotate relative to each other via the central shaft assembly 400, thereby switching the main body between a folded state and an unfolded state.

[0066] Furthermore, both the first housing 200 and the second housing 300 are provided with accommodating grooves (not shown) configured to accommodate electronic elements such as a processor, a circuit board, a camera module, or 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, bearing plates (not shown) are provided on the inner surfaces of the first housing 200 and the second housing 300, which are used to pack the accommodating grooves, on which the display 100 is mounted, and which support 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, with the first bezel 220 surrounding three sides of the first intermediate frame 210 and a first mounting groove 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 a bearing plate may be arranged to support a 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 a 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 first sub-bezel 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 disposed in a convex shape on the first end surface 2210. The thickness of the first exterior body 2211 in the X-axis direction, i.e., the thickness direction of the first sub-bezel 221, 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 surface 2211a facing away from the first exterior surface. The first exterior surface is exposed to the outside of the electronic device and is flush with the outer surface of the first sub-bezel 221. The first inner surface 2211a is joined to the first end surface 2210 at an angle. In this embodiment, the angle is 90 degrees, which facilitates assembly 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 surrounding three sides of the second intermediate frame 310, and the second mounting groove located on the fourth side. The second bezel 320 and the second intermediate frame 310 may be enclosed in the receiving groove, and a bearing plate may be arranged to support the second portion 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. The second mounting groove (not shown) is located between the two third sub-bezels 321 and faces the fourth sub-bezel 322, spaced apart.

[0070] Each third sub-bezel 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 disposed in a convex shape on the second end surface 3210. The thickness of the second exterior body 3211 in the X-axis direction, i.e., the thickness direction of the third sub-bezel 321, 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 surface 3211a facing away from the second exterior surface. The second exterior surface is exposed to the outside of the electronic device and is flush with the outer surface of the third sub-bezel 321. The second inner surface 3211a is joined to the second end surface 3210 at an angle. In this embodiment, the angle is 90 degrees, which facilitates assembly 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 first and second mounting grooves. When the foldable electronic device 1000 is in the unfolded state, the first housing 200, the second housing 300, and the central shaft assembly 400 together support the display 100. 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. When the foldable electronic device 1000 is in the folded state, 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 main body structure. In implementation, the surfaces of the first housing 200 and the second housing 300 that support 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 unit 420, and a second rotating unit 430. The first rotating unit 420 and the second rotating unit 430 are symmetrically coupled to both sides of the base 410. The base 410 and the first rotating unit 420 may be rotatably coupled to each other, and the base 410 and the second rotating unit 430 may be rotatably coupled to each other. The specific configuration may be a conventional rotating shaft mechanism, which will not be described here. The central shaft assembly 400 is configured to support the display 100. The first rotating unit 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 unit 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 or folded, the first rotating unit 420 and the second rotating unit 430 rotate independently relative to the base 410. When the unfolding or folding operation is 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. This allows the foldable electronic device 1000 to be positioned in an unfolded state, a folded state, or an intermediate state, and also prevents structural damage to the foldable electronic device 1000 due to excessive rotation of the first housing 200 and the second housing 300.

[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 portion of the first sub-bezel 221, and a portion of the third sub-bezel 321 of the foldable electronic device 1000, arranged obliquely, according to an embodiment of the present application. Figure 6A is a schematic view of the structure of the first shielding body according to an embodiment of 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] Two shields 500 are provided, which are separately disposed 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 shields 500 form the housing of the electronic device, and the surface facing away from the display 100 forms the exterior part of the foldable electronic device 1000. The two shields 500 are disposed symmetrically in the X-axis direction. Of the two shields 500, a first shield 510 is separately disposed at the first end 411 and the second end 412 of the base 410. Of the two shields 500, a second shield 520 is separately disposed at the third end 421 and the fourth end 422 of the first rotating part 420, and two third shields 530 are separately disposed 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 collectively form part of the exterior structure of the foldable electronic device 1000, and can protect the internal components while shielding the internal components of the space in which the central shaft assembly 400 is disposed, thereby improving the appearance of the foldable electronic device 1000. The shielding members 500 are separately disposed on the two ends of the central shaft assembly 400, which can further provide a uniform shielding effect to the two ends of the central shaft assembly 400, making the appearance of the foldable electronic device more simple.

[0077] 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 thereto. In this embodiment, the third surface 5114 may be a convex surface that is an arc-shaped surface. 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 arranged on a side surface of the main shielding body 511. Specifically, the limiting body 512 is arranged convexly on the coupling surface 5111, specifically, is arranged at an intermediate position of the coupling surface 5111, and has two opposing sliding surfaces 5121, 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 in the same direction as the first surface 5112, and the other sliding surface 5121 facing in 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 of the limiting bodies 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 arcuate end face 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 arcuate surface that is recessed into the back surface of the limiting block 5124, and the arcuate end face 5123 of the limiting body 512 and the end face of the limiting block 5124 are flush with the third surface 5114 of the main shield 511. A second shield 520 and a third shield 530 are arranged on both sides of the limiting body 512, respectively. The second shield 520 is partially stacked on the main shield 511, and the third shield 530 is partially stacked on the first shield 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, respectively. 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, respectively. Limiting blocks 5124 limit the second shielding body 520 and the third shielding body 530, respectively.

[0080] 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 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 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 being sector-shaped. It should be understood that the first surface 5206 and the second surface 5207 may have shapes including, but not limited to, 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 arcs fit the shape of the concave curved surface 5124a of the limiting block) and have the same curvature. It can be seen that the second shield 520 has a symmetrical structure. The second arc-shaped convex surface 5203 of the second shield 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] 6C . In the present application, the third shielding body 530 is shown as a sector-shaped block, 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 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 each other. In the present application, the structure of the third shielding body 530 is shown with the third surface 5306 and the fourth surface 5307 as a sector. It should be understood that the third surface 5306 and the fourth surface 5307 include shapes such as, but are not limited to, a sector, an ellipse, or a rectangle. The third side surface 5300, the third arc-shaped convex surface 5301, the second top surface 5302, the fourth arc-shaped convex surface 5303, the fourth side surface 5304, and the second bottom surface 5305 are connected in sequence. The third side surface 5300, the third arc-shaped convex surface 5301, the second top surface 5302, the fourth arc-shaped convex surface 5303, and the fourth side surface 5304 are connected in sequence smoothly. The third side surface 5300 and the second bottom surface 5305 are connected at an included angle, and the fourth side surface 5304 and the second bottom surface 5305 are connected at an included angle. The second top surface 5302 faces the second bottom surface 5305, and the third arc-shaped convex surface 5301, the second top surface 5302, and the fourth arc-shaped convex surface 5303 are arcs with 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 arcs fit 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 has 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, which is spaced apart 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 a metal material, which can prevent deformation that is difficult to recover from during use scenarios such as high temperature or long-term bending, ensuring the aesthetic appearance of the foldable electronic device and improving 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 surface 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 the unfolded state. The two shielding members 500 are symmetrical. The assembly relationship between the shielding member 500 and the central shaft assembly 400 will be described using one shielding member 500 as an example.

[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 FIGS. 2 and 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 portion of the second shielding body 520 and a portion 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 a rotation gap is provided 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 a rotation gap is provided 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 are overlapping portions 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. A 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. A 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 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 together function as the outer end surfaces of both ends of the main body, i.e., the exterior surface.

[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 shield 520 and the third shield 530 are respectively located in the gap between the first shield 510 and the first housing 200 and the gap between the first shield 510 and the second housing 300. 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 shield 520 and the third shield 530 rotate separately by a specific angle relative to the first shield 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 collectively form one exterior surface of the foldable electronic device 1000. The first shielding body 510, the second shielding body 520, and the third shielding body 530 collectively cover the gap between the first sub-bezel 221 and the third sub-bezel 321. Specifically, the second shielding body 520 has portions that overlap with 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, with no gap in the Y direction. Like the second shielding body 520, the third shielding body 530 has portions that overlap with both the second outer body 3211 of the third sub-bezel 321 and the first shielding body 510, and there are no gaps 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. When the foldable electronic device 1000 is in the unfolded or folded state, there are no gaps 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 are no gaps 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 center 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 shielding body 520 includes two arcuate convex surfaces arranged opposite each other, i.e., a first arcuate convex surface 5201 and a second arcuate convex surface 5203. The third shielding body 530 includes two arcuate convex surfaces arranged opposite each other, i.e., a third arcuate convex surface 5301 and a fourth arcuate convex surface 5303. One of the arcuate convex surfaces of the second shielding body 520 and one of the arcuate convex surfaces of the third shielding body 530 are each arranged opposite two concave curved surfaces 5124a. That is, the first arcuate convex surface 5201 of the second shielding body 520 faces the concave curved surface 5124a of the limiting body 512 and is spaced apart from it to form a rotational gap, and the third arcuate convex surface 5301 of the third shielding body 530 faces the other concave curved surface 5124a of the limiting body 512 of the first shielding body 510 and is spaced apart from it to form a rotational gap. The other arc-shaped convex surface of second shielding body 520 and the other arc-shaped convex surface of third shielding body 530 are able to slide and rotate relative to the end surfaces of first housing 200 and second housing 300, respectively. That is, second arc-shaped convex surface 5203 of second shielding body 520 faces first end surface 2210 with a gap therebetween, first surface 5206 of second shielding body 520 faces first inner surface 2211a of first sub-bezel 221, and first end surface 2210 of first sub-bezel 221 faces 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 face 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 face 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 flattening 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 angles of the second shielding body 520, the first shielding body 510 and the third shielding body 530 are determined via the central shaft assembly.

[0093] When the foldable electronic device 1000 is subjected to an external impact, the first sub-bezel 221, the second shield 520, the first shield 510, the third shield 530, and the third sub-bezel 321 sequentially abut against one another, thereby reducing displacement of the components. The first shield 510 overlaps with the second shield 520 and the third shield 530. The overlapping positions of the first shield 510 and the second shield 520 and the first shield 510 and the third shield 530 can enhance the mechanical strength of the exterior housing of the foldable electronic device 1000 in this portion of the central shaft assembly 400, thereby preventing damage to the foldable electronic device 1000 due to insufficient strength at the joints between the first shield 510 and the second shield 520 and the joints between the first shield 510 and the third shield 530. The intermediate frame assembly of the foldable electronic device 1000 presents 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 their 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 small gap between the first shield 510 and the second shield 520 and the small gap between the first shield 510 and the third shield 530 buffers the external force. When an end of the central shaft assembly 400 receives an impact due to an external force, the first shield 510 can bear 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. Therefore, 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 broken down into the second shield 520 and the third shield 530, buffering the external force of the first shield 510. Furthermore, the positions of the base 410 and the first rotating unit 420 are restricted relative to each other, and the positions of the base 410 and the second rotating unit 430 are restricted relative to each other, thereby reducing displacement of the base 410, the first rotating unit 420, and the second rotating unit 430 when subjected to an external impact, reducing deformation of the display, and increasing the mechanical strength of the foldable electronic device 1000. Similarly, when the second shielding member 520 or the third shielding member 530 is subjected to an external impact, part of the energy of the impact is transmitted to the first shielding member 510 to disperse the impact force, thereby effectively protecting the display 100. 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 member 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 part of the impact force back to the first shield 510 to disperse the impact force and protect the display 100.

[0096] Please refer to Fig. 9. Fig. 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. When the foldable electronic device 1000 is in the folded state, the first end surface 2210 faces the second side surface 5204 with a gap, a portion of the first surface 5206 faces the first inner surface 2211a with a gap, the first side surface 5200 faces the sliding surface 5121 with a gap, a portion of the first surface 5206 faces the coupling surface 5111 of the main shield 511, and the first arc-shaped convex surface 5201 faces the concave surface 5124a with a rotation gap. The other limiting block 5124 has a concave curved surface 5124a facing the third arc-shaped convex surface 5301 with a rotation gap, the other sliding surface 5121 facing the third side surface 5300 with a gap, a part of the third surface 5306 facing the coupling surface 5111 of a part of the main shield 511, the fourth side surface 5304 facing the second end surface 3210 with a gap, and a part of the third surface 5306 facing the second inner side surface 3211a and spaced apart. Since the first shielding body 510, the second shielding body 520, the third shielding body 530 and the first sub-bezel 221, 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 restrict each other and distribute 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 sequentially restrict each other. The first side surface 5200 and one sliding surface 5121 contact each other to restrict each other, and the third side surface 5300 and the other sliding surface 5121 contact each other to restrict each other, and therefore the second shield 520, the first shield 510, and the third shield 530 sequentially abut each other to restrict each other. The fourth side surface 5304 and the second end surface 3210 come into contact with each other to provide a limit, and therefore the third shield 530 and the second housing 300 can abut against each other to provide a limit.

[0098] In addition, when the foldable electronic device 1000 is folded and an end of the folding portion is subjected to an impact from 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 may 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 shield 510, the first top surface 5202 of the second shield 520, and the second top surface 5302 of the third shield 530 may all form an arc shape. The arc shape can make the appearance of the first shield 510, the second shield 520, and the third shield 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. When the foldable electronic device 1000 is folded, the angular positioning provided by the first shield 510, the second shield 520, and the third shield 530, and the angular restriction provided to the first housing 200 and the second housing 300 by the second shield 520 and the third shield 530 are performed via the central shaft assembly 400. That is, 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 shield 510, the second shield 520, and the third shield 530 are also positioned, thereby ensuring the stability of the shielding member 500.

[0100] Please refer to Fig. 10. Fig. 10 is a schematic diagram of another example of the structure of a 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 together, the first housing 200, the second shield 520, the first shield 510, the third shield 530, and the second housing 300 are sequentially arranged in a first direction, and the first shield 510, the second shield 520, and the third shield 530 collectively 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 outer 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 outer 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 and protecting the internal components and concealing the internal components, resulting in a more concise and beautiful appearance.

[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 rotation 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 rotation shaft. Because the second shield 520 is separately coupled to the first shield 510 and the first housing 200 via a rotation shaft, the coupling manner is stable, ensuring that the second shield 520 rotates more efficiently and stably. Because 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 third shield 530 and the end of 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 minimized.

[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 approximately perpendicular to the main shield 511. The first rotation axis 511a and the second rotation axis 511b may be 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 outer 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 outer body 2211. The axial 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 outer body 3211 includes a fourth rotation shaft 3211b. The fourth rotation shaft 3211b is arranged in a convex shape on the second inner surface 3211a of the second outer body 3211. The axial direction of the fourth rotation shaft 3211b may be perpendicular to the second inner 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 3211b. 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 shield 510 may further include a first fastener 511c and a second fastener 511d. After assembly, a portion of the second shield 520 is stacked on the first shield 510, a portion of the second shield 520 is stacked on the first outer body 2211, the first rotation shaft 511a passes through the first through-hole 520a, and the first fastener 511c is coupled to the end of the first rotation shaft 511a, i.e., located on the second surface 5207. The second shield 520 is located between the coupling surface 5111 and the first fastener 511c. The first rotation shaft 511a passes through the first through-hole 520a and is locked via the first fastener 511c. In other words, the second shield 520 is separately rotatably coupled to the first shield 510 and the first sub-bezel 221. The first fastener 511c allows the second shielding body 520 to rotate using only the axial direction of the first rotating shaft 511a as a central axis, thereby reducing sliding of the second shielding body 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 shielding body 530 is disposed between the coupling surface 5111 and the second fastener 511d. The second fastener 511d allows the third shielding body 530 to rotate using only the axial direction of the second rotating shaft 511b as a central axis, thereby reducing sliding of the third shielding body 530 in the axial direction of the second rotating shaft 511b.

[0105] The first outer body 2211 may include a third fastener 2211c. After assembly, the third fastener 2211c is coupled to one end of the third rotation 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 rotation shaft 2211b passes through the second through-hole 520b and is locked 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 rotation shaft 2211b as a central axis, thereby reducing sliding of the second shielding body 520 in the axial direction of the third rotation shaft 2211b.

[0106] The second outer body 3211 may include a fourth fastener 3211c. After assembly, the fourth fastener 2211c is coupled to one end of the fourth rotation shaft 3211b, the fourth fastener being located on the fourth surface 5307, and the third shielding body 530 being disposed between the second inner surface 3211a and the fourth fastener 2211c. The fourth rotation 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 rotation shaft 3211b as a central axis, thereby reducing sliding of the third shielding body 530 in the axial direction of the fourth rotation shaft 3211b.

[0107] Please refer to Figure 12. Figure 12 is a schematic enlarged view of a partial structure of the foldable electronic device 1000 of Figure 10 in an unfolded state. The first shielding body 510 is directly connected to the second shielding body 520 via a first pivot shaft 511a and directly connected to the third shielding body 530 via a second pivot shaft 511b. The first outer body 2211 is directly connected to the second shielding body 520 via a third pivot shaft 2211b, and the second outer body 3211 is directly connected to the third shielding body 530 via a fourth pivot shaft 3211b. Because the second shielding body 520 is separately connected to the first shielding body 510 and the first outer body 2211 via cylinders, the connection state is stable, thereby ensuring more efficient and stable rotation of the second shielding body 520. The third shielding body 530 is coupled to the first shielding body 510 and the second outer body 3211 separately via cylinders, which increases the coupling strength between the third shielding body 530 and the first shielding body 510 and 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 minimized.

[0108] In this embodiment, the first shielding body 510 is directly coupled to the base 410, the second shielding body 520 is not coupled to the first rotating part 420, and the third shielding body 530 is not coupled to the second rotating part 430. During assembly, the center 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 coupled to the cylinder, fasteners are used to restrict the ends of the cylinder to prevent the second shielding body 520 and the third shielding body 530 from falling off. Because the second shielding body 520 is not directly coupled 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 subjected to an external force, the movement function of the first rotating unit 420 is not affected, thereby reducing the impact that the first rotating unit 420 imparts to the display 100 and protecting the display 100. The coupling relationship between the third shield 530 and the first rotating unit 420 is similar to the coupling relationship between the second shield 520 and the first rotating unit 420, and 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 that can protect the interior of the foldable electronic device 1000. In addition, even if the foldable electronic device 1000 is dropped, the movement function of the center shaft assembly 400 is protected and abnormal behavior of the center shaft assembly 400 is reduced, thereby improving the drop reliability of the display 100. 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.
