The foldable electronic device provided in the embodiments of the present application is described below with reference to fig. 1 to 12.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a foldable electronic device 000 provided in an embodiment of the present application in a flattened state. The foldable electronic device 000 is a mobile phone comprising a foldable display screen 100. The foldable display screen 100 includes a first display area 110, a second display area 120, and a third display area 130. Wherein the third display region 130 is connected between the first display region 110 and the second display region 120. In the flattened state, the third display area 130 is flattened such that the first display area 110 and the second display area 120 of the foldable electronic device 000 are substantially 180 ° therebetween.

The foldable display 100 includes a display surface, i.e., a surface on which the foldable display 100 is shown. Wherein, the display surface is a surface of the foldable display screen 100 for emitting light. It should be understood that, in the embodiment of the present application, the thickness direction of the foldable display screen 100 is the same as the thickness direction of the foldable electronic device 000, and both are the illustrated Z direction, i.e. the direction perpendicular to the display surface; the length direction of the foldable display screen 100 is the same as the length direction of the foldable electronic device 000, and is the X direction of the drawing, that is, the direction of the folding edge of the display surface; the width direction of the foldable display screen 100 is the same as the width direction of the foldable electronic device 000, and is the Y direction shown in the figure, that is, the direction of the non-folding edge of the display surface. Note that the folding side of the display surface refers to a side of the display surface that is folded following the folding of the foldable display screen 100; the non-folding edge of the display surface refers to the edge of the display surface that follows the fold of the foldable display screen 100 without being folded.

Referring to fig. 2, fig. 2 is a schematic structural diagram of the foldable electronic device 000 shown in fig. 1 in an incompletely folded state. In the incompletely folded state, the third display region 130 is bent such that an angle between the first display region 110 and the second display region 120 of the foldable electronic device 000 is greater than 0 ° and less than 180 °. It should be noted that the foldable electronic device 000 shown in fig. 1 may also be in a fully folded state, in which the distance between the first display area 110 and the second display area 120 of the foldable electronic device 000 is approximately 0 °.

In this embodiment, the foldable display screen 100 is a foldable screen of the foldable electronic device 000, that is, when the foldable electronic device 000 is folded, the display surface of the foldable display screen 100 is located inside the foldable electronic device 000. It is understood that in some other embodiments of the present application, the foldable display screen 100 may also be an outward folding screen of the foldable electronic device 000, that is, when the foldable electronic device 000 is folded, the display surface of the foldable display screen 100 is located at the outer side of the foldable electronic device 000.

It should be noted that the foldable display screen 100 may be a flexible foldable screen. The flexible folding screen comprises a folding edge made of flexible materials. The foldable display screen 100 can be folded along the folding edges to form a first display area 110, a second display area 120, and a third display area 130. Part or all of the flexible folding screen is made of flexible materials. For example: only the foldable part (such as a foldable edge) in the flexible folding screen is made of flexible materials, and the other parts are made of rigid materials; or the flexible folding screen is made of flexible materials.

For example, the flexible display screen may be an Active Matrix Organic Light Emitting Diode (AMOLED) display screen. The AMOLED display screen is a self-luminous display screen, and a Back Light Module (BLM) is not required. Therefore, when the substrate in the AMOLED display screen is made of a flexible resin material, such as polyethylene terephthalate (PET), the AMOLED display screen can have a bendable characteristic.

Referring to fig. 1 and fig. 3 together, fig. 3 is a schematic structural diagram of the foldable electronic device 000 shown in fig. 1 with the foldable display screen 100 removed. To implement the folding function of the foldable electronic device 000, the foldable electronic device 000 further includes a housing assembly. The housing assembly includes a first middle frame 200, a second middle frame 300, and a rotary shaft assembly 400.

The first middle frame 200 includes a first middle plate 210 and a first rim 220 surrounding the first middle plate 210. The side edge of the first middle plate 210 is connected to the inner surface of the first rim 220. The first display area 110 is disposed opposite to the first middle plate 210 and fixed on the first middle plate 210, and the first middle plate 210 is used for bearing the first display area 110. The second middle frame 300 includes a second middle plate 310 and a second rim 320 surrounding the side of the second middle plate 310. The side edges of the second middle plate 310 are connected to the inner surface of the second rim 320. The second display area 120 is disposed opposite to the second middle plate 310 and fixed on the second middle plate 310, and the second middle plate 310 is used for bearing the second display area 120.

The hinge assembly 400 is opposite to the third display area 130, and is used for supporting the third display area 130. The first middle frame 200 and the second middle frame 300 are positioned at both sides of the rotary shaft assembly 400 and are rotatably connected with the rotary shaft assembly 400, respectively. The first middle frame 200 and the second middle frame 300 can rotate around the rotation shaft assembly 400, so as to drive the first display area 110 to rotate relative to the third display area 130, thereby realizing the folding or unfolding of the foldable display screen 100.

It should be understood that in other embodiments, the foldable display screen 100 may be integrated with a support plate, in which case, the area of the support plate located in the third display area 130 needs to be configured to be foldable, such as spaced bar-shaped support bars, which is not particularly limited in the embodiments of the present application.

It should also be understood that fig. 1-3 illustrate an example of a single fold that may be implemented by the foldable electronic device 000. In other embodiments, foldable electronic device 000 may also be folded multiple times to achieve a smaller area. In this case, the foldable electronic device 000 includes more sets of hinge assemblies 400 and more sets of middle frames, so as to fold the foldable display screen 100 into more display areas, which is not particularly limited in the embodiment of the present application.

Referring to fig. 1 and fig. 3, the third display region 130 can be further divided into a first turning region 131, a second turning region 132 and a folding region 133.

The rotation shaft assembly 400 further includes a central shaft 430, a first rotation shaft 410, and a second rotation shaft 420. Only the relative positions of the central shaft 430, the first rotating shaft 410 and the second rotating shaft 420 are shown in the drawings, and the specific structures of the central shaft 430, the first rotating shaft 410 and the second rotating shaft 420 are not illustrated.

The first rotating shaft 410 and the second rotating shaft 420 are respectively located at two sides of the central shaft 430 and are rotatably connected to the central shaft 430. The first rotating shaft 410 is rotatably connected to the first middle plate 210 at a side away from the central shaft 430. A side of the second rotating shaft 420 distant from the central axis 430 is rotatably coupled to the second middle plate 210.

In the present embodiment, the axial direction of the center shaft 430, the first rotating shaft 410, and the second rotating shaft 420 is the Y direction shown in the drawing, and the radial direction of the center shaft 430, the first rotating shaft 410, and the second rotating shaft 420 is the X direction shown in the drawing. The first rotating shaft 410 and the second rotating shaft 420 are provided on both sides of the central shaft 430 in the radial direction.

The first turning region 131 of the third display region 130 is stacked on the first rotating shaft 410 for bearing the first turning region 131; the second turning region 132 of the third display region 130 is stacked on the second rotation axis 420 for supporting the second turning region 132; the folding region 133 of the third display region 130 is stacked on the central shaft 430 to carry the folding region 133.

In this embodiment, when the foldable electronic device 000 of the present application needs to be folded, a user applies force to the first middle frame 200 and the second middle frame 300, so that when one end of the first middle frame 200 away from the rotation shaft assembly 400 and one end of the second middle frame 300 away from the rotation shaft assembly 400 are close to each other, the first rotation shaft 410 and the second rotation shaft 420 of the rotation shaft assembly 400 rotate relative to the central shaft 430, and the first middle frame 200 and the second middle frame 300 rotate relative to the rotation shafts connected thereto, so that the third display area 130 of the foldable display screen 100 is folded, and the first display area 110 and the second display area 120 are folded relative to the third display area 130; when the foldable electronic device 000 needs to be unfolded, a user applies a force to the first middle frame 200 and the second middle frame 300, so that when one end of the first middle frame 200, which is far away from the rotation shaft assembly 400, and one end of the second middle frame 300, which is far away from the rotation shaft assembly 400, are far away from each other, the first rotation shaft 410 and the second rotation shaft 420 of the rotation shaft assembly 400 rotate and unfold with respect to the central shaft 430, and the first middle frame 200 and the second middle frame 300 rotate and unfold with respect to the rotation shafts connected thereto, so that the third display area 130 of the foldable display screen 100 is unfolded, and the first display area 110 and the second display area 120 are unfolded with respect to the third display area 130.

It should be appreciated that in other embodiments, the third display area 130 may also include more turning areas, in which case the number of axes of rotation is increased accordingly. In addition, in other embodiments, the third display area 130 may only include the folding area 133. In this case, both sides of the folding region 133 are connected to the first display region 110 and the second display region 120, respectively, and in this case, the rotation shaft assembly 400 may include only the center shaft 430, and the center shaft 430 is directly connected to the first middle plate 210 and the second middle plate 310. The embodiment of the present application is not particularly limited to this.

It should be noted that a certain gap is formed between the edge of the first display area 110 and the first frame 220; a gap is formed between the side of the second display region 120 and the second frame 320. The gap is provided to prevent the edge of the foldable display screen 100 from being damaged by collision or the like. Of course, in other embodiments, the collision may be prevented in other manners, such as filling a collision-preventing material (e.g., sponge) between the edge of the display area and the frame.

Referring to fig. 1 and 3 together, in order to improve the appearance of the foldable electronic device 000, the foldable electronic device 000 further includes a first edge guard 510 and a second edge guard 520. In one embodiment, the edge guard is also referred to as the a-shell.

The first edge guard 510 is located on a side of the first display area 110 away from the first middle plate 210. The first edge guard 510 is to cover an edge of the first display area 110 and an edge of the first turning area 131. The second edge guard 520 is positioned at a side of the second display area 120 away from the second middle plate 310, and the second edge guard 520 serves to cover an edge of the second display area 120 and an edge of the second turning area 132. In this way, the first edge protection part 510 and the second edge protection part 520 can respectively shield the edges of the first display area 110 and the second display area 120 and the edges of the first turning area 131 and the second turning area 132, so as to avoid the edges of the first display area 110 and the second display area 120, thereby improving the appearance effect of the foldable electronic device 000.

Specifically, the outer edge of the first edge guard 510 is fixed on the first bezel 220 and is stacked on the first display region 110 and the first turning region 131 to cover the edges of the first display region 110 and the first turning region 131; the outer edge of the second edge guard 520 is fixed on the second bezel 320 and is stacked on the edge of the second display region 120 and the second hinge region 132 to cover the edge of the second display region 120 and the edge of the second hinge region 132.

The two shaft seats 450 form a certain accommodating space with the shaft seats 450 for accommodating the central shaft 430. Thus, the shaft cover 440 covers a side of the central shaft 430 away from the foldable display screen 100, and the shaft seat 450 covers an end of the central shaft 430 in the length direction (i.e., the Y direction shown in the figure), so as to prevent the central shaft 430 from being exposed, so that the foldable electronic device 000 has a good appearance and can play a role in protection.

With continued reference to fig. 3, the foldable electronic device 000 further includes two protective members 600 respectively disposed at two ends of the foldable display screen 100 in the length direction (i.e., the illustrated Y direction) of the folding area 133. The protective assembly 600 can protect the edge of the folding area 133 of the foldable display screen 100, and prevent the edge of the folding area 133 of the foldable display screen 100 from being exposed outside, on one hand, the appearance effect of the foldable electronic device 000 can be improved, on the other hand, the edge of the folding area 133 of the foldable display screen 100 can be prevented from being damaged due to collision, and water, dust and the like can be prevented from permeating into the foldable display screen 100 or the foldable electronic device 000 through the edge of the folding area 133 of the foldable display screen 100, so that the higher reliability of the foldable display screen 100 and the foldable electronic device 000 is ensured. The technical effect of the shield assembly 600 is specifically analyzed below with reference to fig. 4 to 12.

The first protection member 610 includes a protection body 611 and an inverted structure 612 disposed on the protection body 611. The second protection member 620 has an inverted groove 6211 formed thereon and adapted to the inverted structure 612. The protection body 611 is inserted into the inverted groove 6211 through the inverted structure 612, and is fastened with the second protection member 620. In this way, the first guard part 610 and the second guard part 620 can be firmly buckled together and cannot be easily separated.

Illustratively, the undercut structure 612 is a T-shaped structure and the undercut groove 6211 is a T-shaped slot. After the T-shaped structure of the back-off structure 612 is embedded into the T-shaped groove, the head of the T-shaped structure is engaged with the head of the T-shaped groove to form a firm connection. In other embodiments, the above-mentioned reversing structure 612 can also be a snap structure, i.e. the end of the reversing structure 612 extending into the reversing groove 6211 has a barb. Of course, the undercut structure 612 may have other configurations as long as the first protection member 610 and the second protection member 620 can be securely turned back together, and the structure of the undercut structure 612 is not particularly limited in the embodiments of the present application.

Referring to fig. 6, fig. 6 isbase:Sub>A cross-sectional view of fig. 4 taken along the sectional linebase:Sub>A-base:Sub>A. As shown in fig. 6, the guard 611 may be constructed in a plate-like structure. The shield body 611 includes a connection portion 6111 and a fixing portion 6112 connected to the connection portion 6111. The inverted structure 612 is disposed on the connecting portion 6111, and the fixing portion 6112 is used to fix the protective assembly 600 on the foldable electronic device 000. It should be understood that in other embodiments, the protection body 611 may also be configured as a block structure, and the embodiments of the present application are not limited thereto.

Referring to fig. 7, 8 and 9 together, fig. 7 is a schematic structural view of the region a shown in fig. 3, and the schematic structural view also illustrates a relationship between the shield assembly 600 and the rotating shaft assembly 400 shown in fig. 4; FIG. 8 is a schematic view of a portion of the structure shown in FIG. 7 with the shield assembly 600 removed; fig. 9 is a partial structure view of fig. 7 taken along a section line B-B.

In this embodiment, the fixing portion 6112 fixes the shielding assembly 600 on the shaft seat 450 of the rotating shaft assembly 400. Wherein, the shaft seat 450 is provided with an insertion slot 451 (shown in fig. 8), and the fixing portion 6112 of the protection body 611 is inserted into the insertion slot 451 and fixed with the inner wall of the insertion slot 451 (shown in fig. 9), so as to fix the protection assembly 600 on the shaft seat 450 (shown in fig. 7) of the rotating shaft assembly 400. In other embodiments, the fixing portion 6112 of the protection body 611 can be fixed to the shaft seat 450 by other means. For example, the fixing can be performed by various ways such as opening and closing, and fixing with screws, which are not described in detail herein. In addition, in other embodiments, the shielding assembly 600 may also be fixed to both ends of the central shaft 430, and the embodiments of the present application are not limited in particular.

Referring to fig. 10, fig. 10 is a schematic structural view of the foldable display screen assembled on the base of fig. 9. When the shield assembly 600 is fixed to the shaft seat 450 of the rotation shaft assembly 400, the shield assembly 600 is disposed at one side of the edge of the folding region 133 of the foldable display screen 100. In this way, the protection body 611 covers the side of the edge of the folding region 133, so as to avoid the side of the edge of the folding region 133 (i.e. the side of the folding region 133 facing the outside of the foldable electronic device 000) from being exposed. In this case, when the foldable electronic device 000 receives external impact forces directed toward the inside of the foldable electronic device 000 in the Y direction and the Z direction (or the Z direction), the collision force will act on the shield body 611 without directly acting on the folding area 133 of the foldable display screen 100, so that the edge of the folding area 133 of the foldable display screen 100 can be prevented from being impacted, and the reliability of the foldable electronic device 000 can be further improved.

It should be appreciated that first guard 610 is configured to be of a hard texture for a crash-proof effect. For example, the first protection member 610 having a hard texture may be obtained by Metal Injection Molding (MIM), or may be formed by CNC (computer numerical control) machining, die casting, or the like.

With continued reference to fig. 10, in the unfolded state, the protection component 600 is disposed between the edge of the folding area 133 of the foldable display screen 100 and the frame of the foldable electronic device 000. Only half of the barrier assembly 600 is shown in fig. 10 as being positioned between the edge of the folding area 133 of the foldable display screen 100 and the first bezel 220, it being understood that the other half of the barrier assembly 600 is positioned between the edge of the folding area 133 of the foldable display screen 100 and the second bezel 320. In this way, in the flattened state, the protective assembly 600 will be covered by the frame of the foldable electronic device 000, so that the appearance effect of the foldable electronic device 000 can be improved.

Referring to fig. 9 again, the connecting portion 6111 includes a first surface 6111a and a second surface 6111b opposite to each other in the Y direction. When the shield assembly 600 is fixed to the rotation shaft assembly 400, the first surface 6111a of the connection portion 6111 is closer to the outside of the foldable electronic device 000 than the second surface 6111b of the connection portion 6111. The above-mentioned inverted structure 612 is specifically disposed on the second surface 6111b of the connecting portion 6111.

The fixing portion 6112 includes a first surface 6112a and a second surface 6112b which are oppositely arranged in the Y direction. When the shield assembly 600 is fixed on the rotating shaft assembly 400, the first surface 6112a of the fixing portion 6112 is closer to the outside of the foldable electronic device 000 than the second surface 6112b of the fixing portion 6112.

The connection position between the fixing portion 6112 of the protection body 611 and the connecting portion 6111 of the protection body 611 forms a stepped structure, and the first surface 6112a of the fixing portion 6112 of the protection body 611 is lower than the first surface 6111a of the connecting portion 6111. That is, the first surface 6112a (i.e., the surface facing away from the folding zone 133) of the fixing portion 6112 is concave toward the folding zone 133. In this way, when the fixing portion 6112 of the protection body 611 is inserted into the slot 451, the first surface 6111a of the connecting portion 6111 can be flush with the outer surface of the shaft seat 450, so as to ensure a good appearance of the foldable electronic device 000 in the folded state (when the foldable electronic device 000 is in the folded state, the first surface 6111a of the connecting portion 6111 and the shaft seat 450 will be exposed).

Referring to fig. 9 and 10, a groove 6121 is disposed on the second surface 6111b of the connecting portion 6111, and the groove 6121 is located between the inverted structure 612 and the fixing portion 6112. As shown in fig. 10, when the foldable display screen 100 is mounted in place, the edge of the folding area 133 of the foldable display screen 100 is spaced apart from the groove bottom and the groove wall of the groove 6121. As such, when the foldable electronic device 000 receives external impact forces directed toward the inside of the foldable electronic device 000 in the Y direction and the Z direction (or the Z direction), collision forces act on the protective body 611. Due to the existence of the space, the collision force is not easily transmitted to the foldable display screen 100 to damage the foldable display screen 100, so that the edge of the folding area 133 of the foldable display screen 100 can be prevented from being impacted, and the reliability of the foldable electronic device 000 can be further improved. In addition, the groove 6121 may also reserve a space for movement in the Z direction when the folding area 133 of the foldable display screen 100 is bent, so as to avoid interference with the bending of the folding area 133 of the foldable display screen 100.

Referring to fig. 5, 7, 9, 10 and 11, fig. 11 is a schematic structural view of the partial structure shown in fig. 7 when the foldable display screen 100 is assembled, and the view illustrates a matching relationship between the foldable display screen 100 and the second protection member 620. The second prevention piece 620 includes a deformation portion 621 for covering an edge of the folding region 133. The deformation portion 621 includes a first surface 621a and a second surface 621b opposite to each other in a first direction (i.e., the Y direction). The insertion groove 6211 is formed on the first surface 621a of the deformation portion 621. The protection body 611 is disposed on a side of the deformation portion 621 facing the first surface 621a, and is inserted into the inverted groove 6211 from the first surface 621a of the deformation portion 621 through the inverted structure 612 to be fastened with the deformation portion 621. As shown in fig. 10 and 11, when the shield assembly 600 is fixed with the shaft seat 450, the first surface 621a of the deformation portion 621 is closer to the outside of the foldable electronic device 000 than the second surface 621b of the deformation portion 621. In this case, the deformation portion 621 is located further inside than the protection body 611, so the deformation portion 621 can be located on a side of the foldable display screen 100 away from the central axis 430 (i.e., a side toward which the display surface of the foldable display screen 100 faces) to cover an edge of the folding area 133.

Referring to fig. 12, fig. 12 is a schematic structural diagram of the region B shown in fig. 2. This figure illustrates the change in shape that occurs when the shield assembly 600 is folded in conjunction with the folding of the foldable display screen 100. In order not to interfere with the folding of the folding region 133 of the foldable display screen 100, the second shielding member 620 is configured to have a soft texture. For example, the second prevention piece 620 of soft texture can be bent to be deformed, and may be made of a soft rubber material that can be elastically deformed. In this way, when the folding region 133 of the foldable display screen 100 is folded, the flexible deformation portion 621 follows the folding region 133 of the foldable display screen 100 to fold, so as to fold the foldable electronic device 000.

Illustratively, the soft rubber material may be silicone rubber, thermoplastic elastomer (TPE), thermoplastic polyurethane elastomer rubber (TPU), polyvinyl chloride (PVC) soft rubber, rubber (such as silicone rubber, natural rubber, butadiene rubber, styrene butadiene rubber, propylene rubber, etc.), etc., which are not listed herein.

Referring to fig. 9 and 11, the deformation portion 621 further includes a third surface 621c and a fourth surface 621d opposite to each other in the second direction (i.e., the Z direction). Wherein the third surface 621c and the fourth surface 621d of the deformation portion 621 are connected between the first surface 621a and the second surface 621b of the deformation portion 621. When the shield assembly 600 is fixed to the rotation shaft assembly 400, the fourth surface 621d of the deformation portion 621 faces the foldable display screen 100.

The third surface 621c of the deformation portion 621 is an arc surface, and the arc surface is raised in a direction away from the fourth surface 621d of the deformation portion 621. In this embodiment, the third surface 621c of the deformation portion 621 is exposed when the foldable electronic device 000 is in the flattened state, and therefore, the third surface 621c is set to be an arc surface protruding in a direction away from the fourth surface 621d of the deformation portion 621, so that the transition of the foldable electronic device 000 at the position can be smoother, and a good appearance of the foldable electronic device 000 in the flattened state can be ensured. Of course, in other embodiments, the third surface 621c of the deformation portion 621 may also be a plane, which is not specifically limited in this application.

Referring to fig. 5, 7 and 10, the deformation portion 621 includes a first end 621A and a second end 621B opposite to each other in the third direction (i.e., the X direction). The second guard 620 further includes two extending portions, namely a first extending portion 6221 and a second extending portion 6222. The first extending portion 6221 is connected to the first end 621A of the deformation portion 621 and extends along a third direction (i.e., the X direction shown in the figure); the second extending portion 6222 is connected to the second end 621B of the deformation portion 621 and extends along the third direction.

In this embodiment, when the shield assembly 600 is fixed on the hinge assembly 400, the first extending portion 6221 extends between the first edge shield 510 and the foldable display screen 100, i.e., presses the side of the first edge shield 510 facing the foldable display screen 100. The second extension 6222 extends between the second edge guard 520 and the foldable display screen 100, i.e., presses the side of the second edge guard 520 facing the foldable display screen 100. In this way, the shape of the deformation portion 621 can be further maintained, and the problem that the deformation portion 621 is deformed after being bent many times along with the foldable display screen 100 and both ends are tilted can be avoided.

Referring to fig. 5, 7 and 10, each of the first extension portion 6221 and the second extension portion 6222 includes a first side surface and a second side surface arranged along the Y direction, the first side surface is a surface closer to the outside of the foldable electronic device 000, and the first side surface faces the side of the edge of the folding area 133.

The second prevention piece 620 further includes two reinforcing portions, i.e., a first reinforcing portion 6231 and a second reinforcing portion 6232. Wherein, the first reinforcing portion 6231 is connected to the first side surface of the first extending portion 6221 and extends along the second direction (i.e., the illustrated Z direction); the second reinforcing portion 6232 is connected to a first side surface of the second extending portion 6222 and extends in the Z-direction.

In this embodiment, when the protective assembly 600 is fixed to the rotating shaft assembly 400, the first reinforcing part 6231 extends into the gap between the edge of the foldable display screen 100 and the first rim 220; the second reinforcing portion 6232 extends into a gap between the edge of the foldable display screen 100 and the second bezel 320. In this way, the strength of the first extension portion 6221 and the second extension portion 6222 can be enhanced, so as to avoid the problem that the deformation portion 621 causes the first extension portion 6221 and the second extension portion 6222 to break after being bent for multiple times along with the foldable display screen 100.

In this embodiment, the first reinforcing portion 6231, the first extending portion 6221 and the deforming portion 621 may be formed integrally by injection molding or may be formed by adhesion at a later stage, which is not particularly limited in this embodiment of the present invention.

In the above embodiment, the first protection component 610 and the second protection component 620 may be manufactured and molded separately, and then the first protection component 610 and the second protection component 620 are connected by means of a dispensing and sealing method, so as to form the protection assembly 600; the first protection part 610 may be manufactured first, and the T-shaped block and the rubber are directly and integrally injection-molded together when the second protection part 620 is manufactured, so that the processing flow and the cost can be further reduced, which is not particularly limited in the embodiment of the present invention.

In the above embodiment, the protective assembly 600 is located at one side of the edge of the folding area 133 of the foldable display screen 100, the protective body 611 covers the side of the edge of the folding area 133, and the deformation portion 621 covers the display surface of the edge of the folding area 133 of the foldable display screen 100. At this time, the edge of the folding region 133 of the foldable display panel 100 is covered by the protective body and the deformation portion, so that the edge of the folding region 133 of the foldable display panel 100 is prevented from being exposed to the outside, thereby improving the appearance effect of the foldable display panel 100, and it is possible to reduce the penetration of external substances such as water, dust, etc. into the foldable display panel 100 or the foldable electronic device 000 through the edge of the folding region 133 of the foldable display panel 100, thereby improving the reliability of the foldable display panel 100 and the foldable electronic device 000. Moreover, since the edge of the folding area 133 of the foldable display screen 100 is covered by the protection body 611 and the deformation part 621, when the foldable electronic device 000 is collided, the edge of the folding area 133 of the foldable display screen 100 is protected by the protection assembly 600, so that the foldable display screen is not easily damaged by the collision, and the reliability of the foldable electronic device 000 is further improved.

The above description is only an embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be covered within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
