Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of communication, and particularly relates to a folding electronic device. BACKGROUND

[0002] With the development of flexible display technology, folding electronic devices are more and more popular. The folding electronic device comprises a first shell, a second shell, a flexible screen and a hinge mechanism. The first shell and the second shell are rotationally connected through the hinge mechanism. The flexible screen is arranged on the first shell and the second shell. The first shell and the second shell can rotate relative to each other, so as to realize folding and unfolding of the folding electronic device.

[0003] In the related art, the hinge mechanism is an important component of the folding electronic device. The hinge mechanism mainly comprises a hinge base and screen support side plates rotationally installed on both sides of the hinge base through a pin shaft. When the screen support side plates on both sides rotate relative to each other, the bending area of the flexible screen can be bent, so that the flexible screen is folded or unfolded.

[0004] However, in the process of switching between the folded state and the unfolded state of the folding electronic device, the bending area of the flexible screen is prone to interfere with the hinge mechanism, thereby greatly increasing the risk of damage to the flexible screen. SUMMARY

[0005] The purpose of the embodiments of the application is to provide a folding electronic device, which can solve the problem of high risk of damage to the flexible screen of the folding electronic device.

[0006] In order to solve the above technical problems, the application is implemented as follows:

[0007] The folding electronic device provided by the embodiments of the application comprises a frame, a hinge mechanism, a flexible screen, a support and an adhesive.

[0008] The flexible screen is arranged on the frame. The frame comprises a first shell and a second shell. The first shell and the second shell are rotationally connected through the hinge mechanism. The support is located between the flexible screen and the hinge mechanism. At least part of the support is arranged opposite to the bending area of the flexible screen. One of the flexible screen and the hinge mechanism is adhered to the support through the adhesive.

[0009] In the embodiments of the present application, the support is located between the flexible screen and the hinge mechanism, and at least part of the support is arranged opposite to the bending area of the flexible screen. One of the flexible screen and the hinge mechanism is bonded to the support by the bonding member. In this scheme, the hinge mechanism can be separated from the bending area by the support, so as to avoid the risk of interference between the hinge mechanism and the flexible screen, thereby reducing the risk of damage to the flexible screen, and improving the safety and reliability of the foldable electronic device.

[0025] The technical solutions in the embodiments of the present application will be described clearly below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0026] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally means that the front and rear associated objects are in an "or" relationship.

[0027] The folding electronic device provided by the embodiments of the present application will be described in detail below in conjunction with the drawings and specific embodiments and application scenarios.

[0028] Please refer to Figures 1 to 52 The folding electronic device disclosed by the embodiments of the present application includes a frame, a hinge mechanism 200, and a flexible screen 300.

[0029] The frame body comprises a first shell 110 and a second shell 120, and the first shell 110 and the second shell 120 are rotationally connected by a hinge mechanism 200 to make the folding electronic device have an unfolded state and a folded state. Optionally, the hinge mechanism 200 comprises a base 210, screen support side plates and rotating arms, the base 210 provides a mounting basis for other components of the hinge mechanism 200, and the screen support side plates are rotationally connected with the base 210 by the rotating arms. The first shell 110 and the second shell 120 can be rotationally connected with the base 210 by the screen support side plates, so as to realize the relative rotation of the first shell 110 and the second shell 120.

[0030] In an optional embodiment, the number of screen support side plates is two, comprising a first screen support side plate 220 and a second screen support side plate 230, and the first screen support side plate 220 and the second screen support side plate 230 are respectively located on both sides of the base 210, the first screen support side plate 220 corresponds to the first shell 110, and the second screen support side plate 230 corresponds to the second shell 120. The rotating arms comprise a first rotating arm 240 and a second rotating arm 250, the first screen support side plate 220 is rotationally connected with the base 210 by the first rotating arm 240, and the second screen support side plate 230 is rotationally connected with the base 210 by the second rotating arm 250. Of course, the specific structure of the hinge mechanism 200 is prior art, and details are not described herein.

[0031] The flexible screen 300 is arranged on the frame body, and optionally, the flexible screen 300 is arranged on the first shell 110 and the second shell 120. At this time, the flexible screen 300 changes with the relative rotation position of the first shell 110 and the second shell 120 to realize the unfolding and folding of the folding electronic device.

[0032] The folding electronic device disclosed in the present application can be an outer folding electronic device or an inner folding electronic device. For example, the folding electronic device can be an outer folding electronic device. When the folding electronic device is in a folded state, the volume of the folding electronic device is small, and at this time, the folding electronic device can only use the screen area on the first shell 110 or the second shell 120. At this time, the front and back of the electronic device are both two independent display areas. When the folding electronic device is in an unfolded state, the volume of the electronic device increases, the display area of the flexible screen 300 on the first shell 110 and the display area of the flexible screen 300 on the second shell 120 form a large overall display area, so that the display area of the electronic device also increases by several times. Here, the folding electronic device is only provided with one foldable flexible screen 300.

[0033] For another example, the foldable electronic device can be an in-folding electronic device. When the foldable electronic device is in the folded state, the flexible screen 300 is folded inside the frame, and thus an additional display screen needs to be provided on the side of the first housing 110 or the second housing 120 facing away from the flexible screen 300. The additional display screen can be used for display operation when the electronic device is in the folded state.

[0034] The foldable electronic device disclosed in the present application further includes a support 400 and an adhesive 500. The support 400 is located between the flexible screen 300 and the hinge mechanism 200, and at least a part of the support 400 is arranged opposite the bending area 310 of the flexible screen 300. At this time, at least a part of the support 400 can cover the bending area 310. One of the flexible screen 300 and the hinge mechanism 200 is adhered to the support 400 by the adhesive 500. At this time, the support 400 can only be adhered to one of the flexible screen 300 and the hinge mechanism 200, and cannot be adhered to both.

[0035] In a specific operation process, the support 400 can be bent or unfolded together with the flexible screen 300 under the action of the hinge mechanism 200, so as to dynamically match the bending area 310.

[0036] Optionally, the support 400 can be a plate structure, or a layer or sheet structure. The specific shape of the support 400 is not limited herein. The support 400 can be a steel sheet or a bendable plastic structure. Of course, the support 400 can also be made of other materials. The specific material of the support 400 is not limited herein.

[0037] In the embodiments disclosed in the present application, the support 400 can separate the hinge mechanism 200 from the bending area 310, so as to avoid the risk of interference between the hinge mechanism 200 and the flexible screen 300, thereby reducing the risk of damage to the flexible screen 300, and improving the safety and reliability of the foldable electronic device.

[0038] In addition, the support 400 can also cover the hole or hole area on the hinge mechanism 200, thereby improving the support reliability of the flexible screen 300 and avoiding local concave deformation of the flexible screen 300. In addition, the support 400 covering the hole or hole area on the hinge mechanism 200 can avoid the risk of air intake failure of the main screen caused by the whole machine falling and colliding of the foldable electronic device.

[0039] In the embodiments disclosed in the present application, the support 400 is arranged between the bending area 310 and the hinge mechanism 200, which can weaken the influence of the unevenness between the base 210 of the hinge mechanism 200 and the screen support side plate, and maximize the uniformity of the crease.

[0040] Further, the folding electronic device can further include a first filling layer 410 and a second filling layer 430, the first filling layer 410 can be attached to the surface of the support 400 on the side facing the flexible screen 300, and the second filling layer 430 can be attached to the surface of the support 400 on the side facing the hinge mechanism 200.

[0041] In this scheme, the filling layer is arranged on both sides of the support 400, so as to prevent the support 400 from directly rubbing against the metal structure of the hinge mechanism 200 and the protective film of the flexible screen 300, thereby reducing the abnormal sound of the folding electronic device caused by rubbing. In addition, the filling layer arranged on both sides of the support 400 can also prevent the lubricating grease of the hinge mechanism 200 from overflowing between the support 400 and the protective film of the flexible screen 300, thereby avoiding the oil overflow abnormal sound of the folding electronic device. Therefore, the folding electronic device disclosed in the present application can further reduce the abnormal sound during the switching process between the folded state and the unfolded state.

[0042] In addition, the filling layer is used to fill the gap between the support 400 and the flexible screen 300 and the support 400 and the hinge mechanism 200, thereby playing a role in improving the drop ball reliability performance and supporting the sag of the flexible screen 300, so as to reduce the sagging degree of the crease of the flexible screen 300, thereby improving the display performance of the folding electronic device.

[0043] Optionally, the first filling layer 410 or the second filling layer 430 is provided with a through hole, the through hole exposes part of the surface of the support 400, and at least part of the adhesive 500 can be located in the through hole, so that the flexible screen 300 or the hinge mechanism 200 is directly bonded to the support 400 through the adhesive 500. Alternatively, the flexible screen 300 can be bonded to the first filling layer 410 through the adhesive 500, and alternatively, the hinge mechanism 200 can be bonded to the second filling layer 430 through the adhesive 500. At this time, the flexible screen 300 and the hinge mechanism 200 are indirectly bonded to the support 400 through the first filling layer 410 and the second filling layer 430.

[0044] In the above embodiment, the support 400 can adopt a hand-torn steel sheet with a thickness of 0.01 mm. In order to ensure the rigidity of the support 400, the support 400 can be composed of three layers of hand-torn steel sheets with a thickness of 0.01 mm. Of course, the thickness of the support 400 can be flexibly selected according to the actual working condition, which is not limited herein. The adhesive 500 can be a double-sided adhesive, glue and the like. Of course, the adhesive 500 can also be other adhesive structures, which is not limited herein.

[0045] In another optional scheme, as shown in FIG. 6, the folding electronic device can further include a first filling layer 410 and a second filling layer 430, the first filling layer 410 can be attached to the surface of the support 400 on the side facing the flexible screen 300, and the second filling layer 430 can be attached to the surface of the support 400 on the side facing the hinge mechanism 200. Figures 1 to 7As shown, the support member 400 can be bonded to the bending area 310 through the bonding member 500. In this scheme, the support member 400 is not prone to relative displacement with the protective film of the flexible screen 300, thus the problem of frictional noise between the support member 400 and the protective film of the flexible screen 300 can be eliminated, and the problem of adsorption noise between the support member 400 and the protective film of the flexible screen 300 can also be avoided. Thus the noise of the foldable electronic device can be further reduced, and the user experience of the foldable electronic device can be further improved.

[0046] In addition, since the support member 400 is bonded to the bending area 310, the support member 400 and the flexible screen 300 are integrated, and thus the support member 400 and the flexible screen 300 are not prone to relative displacement. Thus when the foldable electronic device falls, the support member 400 is not prone to tearing due to the rubbing of the hinge mechanism 200, and thus the safety and reliability of the support member 400 are improved.

[0047] Further, the middle area of the support member 400 can be bonded to the middle area of the bending area 310 through the bonding member 500. Here, the middle area refers to the area near the center of the bending area 310, and can also be understood as the area near the bending center axis of the bending area 310. The bending area 310 is symmetrical about the bending center axis, which can also be understood as the rotation center axis of the hinge mechanism 200, and can also be understood as the center line of the bending area 310. With the center line of the bending area 310 as a reference, a certain range on both sides of the center line and within the bending area 310 defines a first boundary line and a second boundary line parallel to the center line, and the center line is located between the first boundary line and the second boundary line. The distance between the first boundary line and the center line is a first distance, and the area between the second boundary line and the center line is a second distance. The ratio between the first distance and the second distance can be 1:0.8, or 0.8:1. At this time, the area defined between the first boundary line and the second boundary line on the bending area 310 is the middle area of the bending area 310. Of course, the middle area of the support member 400 can also be defined in the above manner, and will not be described herein.

[0048] In this scheme, the bonding member 500 is located in the middle area of the support member 400 and the middle area of the bending area 310. The support member 400 is bonded to the middle area of the bending area 310 through the bonding member 500. After the bending area 310 is bent, the bottom thereof is in the shape of a water droplet, and thus the middle area thereof can be approximately planar. Thus the deformation of the bonding area 422a during the bending and unfolding of the support member 400 is small, and thus the bonding performance is better and the bonding is more firm.

[0049] In addition, the middle region of the support 400 can be bonded to the bending region 310 by the bonding member 500, and the support 400 extends to both sides of the bending region 310 by substantially the same distance, so that the support 400 has more balanced support force on the bending region 310, and has better support effect.

[0050] Further, in the case where the folding electronic device further comprises the first filling layer 410 and the second filling layer 430, the middle region of the support 400 is bonded to the middle region of the bending region 310 by the first filling layer 410 and the bonding member 500. Here, the middle region of the support 400 can be understood as the middle region of the first filling layer 410.

[0051] In the above embodiment, the first filling layer 410 and the second filling layer 430 can be made of materials such as foam, or the first filling layer 410 can be foam and the second filling layer 430 can be high-temperature adhesive paper, and of course the first filling layer 410 and the second filling layer 430 can also be other materials, which are not limited herein.

[0052] In another alternative embodiment, the bonding member 500 can have a first bonding surface and a second bonding surface arranged opposite to each other, the second bonding surface can be a grid bonding surface, the first bonding surface faces the first filling layer 410, and the second bonding surface can face the bending region 310. In this scheme, the grid bonding surface faces the protective film of the flexible screen 300, which not only meets the requirement of firm bonding, but also realizes repeated disassembly, so as to avoid that the bonding member 500 pulls and damages the protective film of the flexible screen 300.

[0053] In another alternative embodiment, as shown in Figure 1 and Figure 8 the bonding member 500 can have a strip-shaped structure, and the extension direction of the bonding member 500 can be the same as the extension direction of the center line of the bending region 310. This scheme can not only make the support 400 firmly bonded to the bending region 310, but also can avoid the like-bonding non-bonding abnormal sound caused by the bonding member 500 pulling the flexible screen 300 as much as possible.

[0054] In another alternative embodiment, in the case where the folding electronic device is in an unfolded state, that is, the hinge mechanism 200, the flexible screen 300 and the support 400 are all in a flattened position, the orthographic projection of the bonding member 500 can be located in the orthographic projection of the first filling layer 410, and the orthographic projection of the first filling layer 410 can be located in the orthographic projection of the support 400.

[0055] In this scheme, the bonding member 500 does not protrude from the first filling layer 410 and the support 400, so as to avoid the risk of adhesion between the bonding member 500 and the hinge mechanism.

[0056] Further, in the unfolded state of the foldable electronic device, the orthographic projection of the support 400 can be located within the orthographic projection of the second filling layer 430. In this scheme, the support 400 is retracted into the second filling layer 430, that is, the edges of the support 400 do not protrude beyond the edges of the second filling layer 430, thereby avoiding the risk of friction between the support 400 and the hinge mechanism 200 during folding or unfolding, further improving the reliability of the foldable electronic device.

[0057] In an alternative embodiment, in the unfolded state of the foldable electronic device, the distance between the edges of the support 400 and the edges of the second filling layer 430 can be greater than or equal to 3 mm, that is, the edges of the second filling layer 430 can protrude beyond the edges of the support 400 by a distance greater than or equal to 3 mm. Of course, the distance between the edges of the support 400 and the edges of the second filling layer 430 can also be other values, which are not limited herein.

[0058] In the related art, in order to reduce the height difference between the rotating arm and the screen support side plate, the screen support side plate is provided with a connecting groove, and part of the rotating arm is located in the connecting groove. However, when the foldable electronic device switches between the unfolded state and the folded state, the edges of the support 400 will slip, thereby easily causing the edges of the support 400 to be inserted into the connecting groove, thus causing the support 400 to be pulled and deformed or broken.

[0059] Based on this, in another alternative embodiment, the edges of the support 400 can be provided with an avoidance notch; the avoidance notch can be oppositely arranged with the connecting groove.

[0060] In an alternative embodiment, the opposite edges of the support 400 can be provided with a first avoidance notch 403 and a second avoidance notch 404, respectively. The first screen support side plate 220 can be provided with a first connecting groove 221, part of the first rotating arm 240 can be located in the first connecting groove 221, and the first avoidance notch 403 can be oppositely arranged with the first connecting groove 221.

[0061] The second screen support side plate 230 can be provided with a second connecting groove 231, part of the second rotating arm 250 can be located in the second connecting groove 231, and the second avoidance notch 404 can be oppositely arranged with the second connecting groove 231.

[0062] In this scheme, the avoidance notch avoids the connecting groove, thereby allowing the support 400 to be retracted at a relatively large position opposite the connecting groove, thereby allowing the edges of the support 400 not to be easily inserted into the connecting groove when the foldable electronic device switches between the unfolded state and the folded state, and further allowing the support 400 not to be easily interfered with the hinge mechanism 200, thereby further improving the safety and reliability of the foldable electronic device.

[0063] In the above embodiment, when the foldable electronic device includes the first filler layer 410 and the second filler layer 430, the first filler layer 410 is not easily inserted into the connecting groove because the orthographic projection of the first filler layer 410 is smaller than the orthographic projection of the support 400, and thus only the avoidance notch needs to be formed in the corresponding position of the second filler layer 430 and the support 400.

[0064] The first foldable electronic device disclosed in the present application is shown in FIG. 1, which includes a support 400, a first filler layer 410, a second filler layer 430, a hinge mechanism 200, a flexible screen 300, and a bonding member 500. Figures 1 to 7 As shown in FIG. 1, the middle region of the support 400 is bonded to the middle region of the bending region 310 through the first filler layer 410 and the bonding member 500. Figures 8 to 10 The structure of the support 400, the first filler layer 410, and the second filler layer 430 in the first foldable electronic device disclosed in the present application is shown in FIG. 2.

[0065] In the embodiment disclosed in the present application, the support 400 can be connected to the hinge mechanism 200. In an alternative embodiment, the support 400 can be connected to the first screen support side plate 220 or the second screen support side plate 230, that is, one side of the support 400 is fixed to the first screen support side plate 220 or the second screen support side plate 230, and the other side is a movable side. At this time, when the foldable electronic device switches between the folded state and the unfolded state, the sliding distance of the support 400 is large, and thus the abnormal sound of the foldable electronic device is large.

[0066] Based on this, the present application further discloses a second foldable electronic device, as shown in FIG. 3, which includes a support 400, a first filler layer 410, a second filler layer 430, a hinge mechanism 200, a flexible screen 300, and a bonding member 500. Figures 11 to 15 As shown in FIG. 3, the surface of the support 400 is provided with a split crack 421, which can separate the support 400 into a fixed part 422 and a bending part 423 that are relatively movably connected. The fixed part 422 can be fixedly bonded to the base 210 of the hinge mechanism 200 through the bonding member 500. As shown in FIG. 4, the fixed part 422 can be fixedly bonded to at least one or more regions of C1, C2, C3, C4, and C5 through the bonding member 500. Figure 52 As shown in FIG. 3, the surface of the support 400 is provided with a split crack 421, which can separate the support 400 into a fixed part 422 and a bending part 423 that are relatively movably connected. The fixed part 422 can be fixedly bonded to the base 210 of the hinge mechanism 200 through the bonding member 500. As shown in FIG. 4, the fixed part 422 can be fixedly bonded to at least one or more regions of C1, C2, C3, C4, and C5 through the bonding member 500.

[0067] In the specific operation process, the fixed part 422 is bonded with the base 210 through the bonding member 500, so that one end of the fixed part 422 is fixed relative to the base 210 during the switching process of the folding electronic device between the folded state and the unfolded state, and the bending part 423 is bent or flattened under the action of the hinge mechanism 200. At the same time, one end of the fixed part 422 is also connected with the bending part, so that the fixed part 422 pulls the bending part 423, thereby avoiding the phenomenon of deviation of the bending part 423 during the bending process.

[0068] In this scheme, the fixed part 422 of the support 400 is fixed on the base 210, and the base 210 is located between the first screen support side plate 220 and the second screen support side plate 230, so that the support 400 is fixed on the middle region of the hinge mechanism 200. Compared with the scheme of single-side bonding of the screen support side plate of the support 400, the sliding distance and the sliding rate of the support 400 are reduced to half of the original, so that the bonding and fixing of the fixed part 422 of the support 400 and the base 210 can reduce the displacement of the support 400 by half, and accordingly the rate is also reduced by half, so that the abnormal sound of the folding electronic device is further reduced.

[0069] In an alternative embodiment, the fixed part 422 can include a bonding area 422a and a connecting area 422b arranged side by side, the bonding area 422a is connected with the bending part 423 through the connecting area 422b, and the bonding area 422a can be bonded with the base 210 through the bonding member 500. The connecting area 422b here can be understood as an elastic arm, which can serve as the bending end of the fixed part 422, thereby realizing the relative movement connection between the bonding area 422a and the bending part 423. It can also be understood that part of the surface of the fixed part 422 is bonded with the base 210 through the bonding member 500, and the area between the bonding member 500 and the bending part 423 is the connecting area 422b. Since there is also a split crack 421 between the bending part 423 and the connecting area 422b, the bending part 423 and the connecting area 422b can be elastically deformed, so that the pulling force of the bending part 423 on the connecting area 422b is small during the switching process of the folding electronic device between the folded state and the unfolded state, and the bonding reliability of the support 400 and the base 210 is high.

[0070] In addition, the fixed part 422 of the support 400 in the present application has a longer elastic arm, so it can accommodate more deformation of the hinge mechanism 200, thereby greatly improving the tearing problem of the support 400, and further improving the reliability and safety of the support 400.

[0071] In an alternative embodiment, as shown in FIG. 8, the fixed part 422 of the support 400 can be fixed on the base 210 through the bonding member 500, and the base 210 is located between the first screen support side plate 220 and the second screen support side plate 230, so that the support 400 is fixed on the middle region of the hinge mechanism 200. Figures 17 to 20As shown, the fixing portion 422 can be a strip structure, one end of the strip structure is a free end, and the other end is a connecting end, and the connecting end is connected to the bending portion 423. At this time, the bonding area 422a is the area on the side of the fixing portion 422 close to the free end, and the connecting area 422b is the area on the side of the fixing portion 422 close to the connecting end.

[0072] In another optional embodiment, as Figures 23 to 25 As shown, the fixing portion 422 may be a cross-shaped structure, wherein two opposite ends of the cross-shaped structure may be connecting ends, and the other two opposite ends may be free ends. The adhesive member 500 is disposed near the free ends.

[0073] In another optional embodiment, as Figures 26 to 28 As shown, the connection area 422b can be an elastic structure, for example, the connection area 422b can be a spring or a mesh structure. Under the action of the elastic structure, the connection distance between the movable portion and the bent portion 423 can be increased, thereby significantly reducing the pulling damage of the connection area 422b on the bonding area 422a, thereby further improving the safety and reliability of the support member 400.

[0074] Of course, the fixing portion 422 can also be Figures 29 to 37 The structure in the scheme shown in this application only discloses several feasible schemes and is not used to limit the specific structure of the fixing part 422. As long as the relative movable structure between the fixing part 422 and the bending part 423 can be achieved, it falls within the protection scope of this application.

[0075] In another optional embodiment, as Figure 20 As shown, the foldable electronic device may further include a first filling layer 410 and a second filling layer 430. The first filling layer 410 may cover the surface of the support member 400 facing the flexible screen 300, and the first filling layer 410 is attached to the bent portion 423. In this case, the first filling layer 410 covers the fixed portion 422. Since the first filling layer 410 is attached to the bent portion 423, the first filling layer 410 also moves relative to the fixed portion 422.

[0076] An adhesive member may be provided on the fixing portion 422 , and a second filling layer 430 may be provided on a surface of the bending portion 423 facing the hinge mechanism 200 .

[0077] In this scheme, the filling layer is arranged on both sides of the support 400, so as to prevent the support 400 from directly rubbing against the metal structure of the hinge mechanism 200 and prevent the support 400 from directly rubbing against the protective film of the flexible screen 300, thereby reducing the abnormal sound of the foldable electronic device caused by rubbing. In addition, the filling layer is arranged on both sides of the support 400, which can also prevent the lubricating grease of the hinge mechanism 200 from overflowing between the support 400 and the protective film of the flexible screen 300, thereby also preventing the oil overflow abnormal sound of the foldable electronic device. Therefore, the foldable electronic device disclosed in the present application can further reduce the abnormal sound during the switching process between the folded state and the unfolded state.

[0078] In addition, the filling layer is used to fill the gap between the support 400 and the flexible screen 300 and the support 400 and the hinge mechanism 200, thereby playing a role in improving the drop ball reliability performance and supporting the sag of the flexible screen 300, so as to reduce the sagging degree of the crease of the flexible screen 300, thereby improving the use performance of the foldable electronic device.

[0079] In the above embodiment, in order to avoid a large gap between the support 400 and the second filling layer 430, the thickness of the second filling layer 430 is slightly smaller than the thickness of the adhesive 500, or the thickness of the second filling layer 430 is equal to the thickness of the adhesive 500.

[0080] In the above embodiment, the connecting area 422b of the fixed part 422 is suspended, which is easy to be damaged. Therefore, in another alternative embodiment, the foldable electronic device can further include a third filling layer 440, the third filling layer 440 and the second filling layer 430 can be arranged side by side, the third filling layer 440 can be bonded to one side of the connecting area 422b facing the base 210, and the second filling layer 430 and the third filling layer 440 can have a separation gap therebetween.

[0081] In this scheme, the third filling layer 440 can support the connecting area 422b, thereby avoiding the suspension of the connecting area 422b, further avoiding the risk of damage to the fixed part 422, and thus further improving the reliability and safety of the support 400. In addition, the second filling layer 430 and the third filling layer 440 are provided with a separation gap therebetween, thereby avoiding the risk of mutual extrusion of the second filling layer 430 and the third filling layer 440 caused by the bending of the bending part 423.

[0082] The first filling layer 410, the second filling layer 430 and the third filling layer 440 herein can all be foam, and of course can also be other materials, which are not limited herein.

[0083] As shown in FIG. 6, the foldable electronic device can further include a third filling layer 440, the third filling layer 440 and the second filling layer 430 can be arranged side by side, the third filling layer 440 can be bonded to one side of the connecting area 422b facing the base 210, and the second filling layer 430 and the third filling layer 440 can have a separation gap therebetween. Figure 20 and Figure 22As shown, the second filling layer 430 can include a plurality of portions, and the plurality of portions of the second filling layer 430 need to reserve exposed regions of the fixing portion 422, so that the fixing portion 422 is exposed through the exposed regions. The specific structure of the second filling layer 430 can be flexibly selected according to actual working conditions, and the specific structure of the second filling layer 430 is not limited in this embodiment. Figure 20 and the accompanying drawings Figure 22 Only one feasible structure is disclosed, which does not limit the specific structure of the second filling layer 430.

[0084] In the above embodiment, since the first filling layer 410 is laid on the surface of the support 400, the fixing portion 422 is easy to adhere to the first filling layer 410, so as to damage the adhesion structure between the fixing portion 422 and the base 210. Therefore, in another alternative embodiment, the foldable electronic device can further include a separation layer 450, which can be arranged between the first filling layer 410 and the support 400, and at least part of the fixing portion 422 can be arranged opposite to the separation layer 450. In this scheme, the separation layer 450 can avoid the fixing portion 422 from adhering to the first filling layer 410, so as not to easily damage the adhesion structure between the fixing portion 422 and the base 210, thereby further improving the reliability and safety of the foldable electronic device.

[0085] Optionally, the separation layer 450 can be made of materials such as foam, plastic, hand-torn steel, etc. Of course, the separation layer 450 can also be made of other materials, which are not limited herein.

[0086] It should be noted that the separation layer 450 is arranged between the fixing portion 422 and the first filling layer 410, and cannot be adhered to the fixing portion 422, and only plays a role of separating the first filling layer 410 and the fixing portion 422.

[0087] In another alternative embodiment, the surface area of the bending portion 423 can be greater than the surface area of the fixing portion 422. In this scheme, the surface area of the bending portion 423 is larger, so as to better support the bending area 310 of the flexible screen 300.

[0088] In another alternative embodiment, the number of the fixing portion 422 can be at least two, and the at least two fixing portions 422 are arranged in a spaced manner along the extension direction of the rotation axis of the hinge mechanism 200. In this scheme, the number of the fixing portion 422 is multiple, so as to increase the adhesion area of the support 400 and the base 210, thereby improving the adhesion reliability of the support 400 and the base 210.

[0089] Optionally, the at least two fixing portions 422 can be arranged symmetrically, which can be central symmetry or axial symmetry. At this time, the adhesion areas of the at least two fixing portions 422 are the same, so that the stress is more balanced.

[0090] The application also discloses a third folding electronic device, as shown in the drawings. Figures 38 to 41 In an optional embodiment, the number of the support members 400 can be at least two, which can include a first support member 401 and a second support member 402, respectively. The adhesive member 500 can include a first adhesive layer 510 and a second adhesive layer 520.

[0091] The first support member 401 can be adhered to the first screen support side plate 220 through the first adhesive layer 510, as shown in the drawings. Figure 52 The first support member 401 can be adhered to the A area through the first adhesive layer 510, and the first support member 401 covers part of the base 210. At this time, part of the first support member 401 extends above the base 210. The second support member 402 can be adhered to the second screen support side plate 230 through the second adhesive layer 520, as shown in the drawings. Figure 52 The second support member 402 can be adhered to the B area through the second adhesive layer 520, and the second support member 402 covers part of the base 210. At this time, part of the second support member 402 extends above the base 210. The first support member 401 and the second support member 402 can be provided with a spacing gap 610.

[0092] At this time, the first support member 401 and the second support member 402 are provided with the spacing gap 610, so that the first support member 401 and the second support member 402 are completely disconnected, which helps the side of the support member 400 fixed to follow the hinge mechanism 200 to bend, and the side not fixed is easy to bend around the middle area of the hinge mechanism.

[0093] Compared with the single support member 400 single-sided fixed mode, the first support member 401 and the second support member 402 can reduce the displacement to half of the original, so the corresponding speed will also be reduced by half, so as to further reduce the abnormal sound of the folding electronic device. In addition, the spacing gap 610 between the first support member 401 and the second support member 402 is opposite to the base 210, and the base 210 is opposite to the bending area 310, so that the spacing gap 610 can avoid the bending area 310 during the folding process of the flexible screen 300, thereby reducing the acting force on the bending area 310 and reducing the damage risk of the bending area 310.

[0094] In the above embodiment, the screen support side plate has a certain gap with the base 210, and the support member 400 is easy to insert below the base 210 during the switching process of the folding electronic device between the folded state and the unfolded state.

[0095] Based on this, in another optional embodiment, one side of the first support 401 towards the second support 402 can be provided with a protruding portion 4011, and the second support 402 is provided with a matching notch 4021 towards the first support 401, and at least part of the protruding portion 4011 can be located in the matching notch 4021.

[0096] In this scheme, the support 400 is provided with the protruding portion 4011, and when the folding electronic device is in the folded state, the protruding portion 4011 can also be lapped on the base 210, so that the support 400 can be prevented from being inserted below the base 210 during dynamic bending, thereby further improving the safety and reliability of the folding electronic device.

[0097] Optionally, the protruding portion 4011 can be provided in the middle region of the first support 401, and of course can also be provided in other regions, which is not limited herein.

[0098] In another optional embodiment, one side surface of the first support 401 and the second support 402 towards the flexible screen 300 can be attached with a corresponding first filling layer 410, and one side of the first support 401 and the second support 402 towards the corresponding screen support side plate can be attached with a corresponding second filling layer 430. The first screen support side plate 220 is attached to the second filling layer 430 corresponding to the first support 401 through the first adhesive layer 510. The second screen support side plate 230 is attached to the second filling layer 430 corresponding to the second support 402 through the second adhesive layer 520.

[0099] The first filling layer 410 and the second filling layer 430 herein have the same functions as the first filling layer 410 and the second filling layer 430 in the above-mentioned embodiments, which will not be repeated herein.

[0100] In the above-mentioned embodiments, the deformation zone of the screen support side plate is prone to deformation, which causes the edge of the support 400 to protrude, and further causes the support 400 to rub against the flexible screen 300 and generate abnormal sound.

[0101] Based on this, in another optional embodiment, the first filling layer 410 provided on the first support 401 can be provided with a first avoiding notch 411 away from the second support 402, and the first avoiding notch 411 can be oppositely arranged with the deformation zone of the first screen support side plate 220.

[0102] The first filling layer 410 provided on the second support 402 can be provided with a second avoiding notch 412 away from the first support 401, and the second avoiding notch 412 is oppositely arranged with the deformation zone of the second screen support side plate 230.

[0103] In this scheme, the avoidance notch on the first filling layer 410 can avoid the deformation area of the screen support side plate, so as not to easily cause the support 400 to be warped, and further not to easily cause the support 400 to rub against the flexible screen 300 to generate abnormal sound.

[0104] Optionally, the screen support side plate is prone to be deformed and protruded, especially at the middle and both sides, so the avoidance notch is arranged at the middle and both sides of the first support 401 and the second support 402.

[0105] In order to improve the bonding strength of the screen support side plate and the support 400, in another optional embodiment, as shown in the figure, Figure 46 the first bonding layer 510 and the second bonding layer 520 can both be provided with a point glue groove 530, and the point glue groove 530 on the first bonding layer 510 and the second bonding layer 520 penetrates the bonding surface. In this scheme, the screen support side plate and the support 400 are fixed by point glue and adhesive, so as to ensure that the support 400 is not prone to relative displacement during bending, and further improve the bonding reliability of the support 400.

[0106] As shown in the figure, Figure 46 the first bonding layer 510 and the second bonding layer 520 both include a first bonding part and a second bonding part arranged side by side, and the first bonding part and the second bonding part can both be double-sided adhesive tape. The first bonding part is provided with a notch, and the second bonding part is arranged close to the notch, so that the first bonding part and the second bonding part enclose the point glue groove 530. Of course, the first bonding layer 510 and the second bonding layer 520 can also have other structures, which are not limited herein. It should be noted that the point glue groove 530 needs to be provided with a point glue discharge port, so as to facilitate the discharge of internal air during point glue and improve the reliability of point glue.

The second region 407 can be bonded to the second screen support side plate 230 by the second bonding layer 520. As shown in the figure, Figure 52 at least part of the second region 407 can be bonded to the B region by the second bonding layer 520. At least part of the telescopic region 406 can be arranged opposite to the bending region 310.

[0108] Specifically, in the case of fixing the two sides of the support 400, the stretchable area 406 stretches along with the hinge mechanism 200, and the support 400, under the joint action of the hinge mechanism 200 and the flexible screen 300, forms a water drop shape wrapping the bending area 310.

[0109] In this scheme, during the folding of the hinge mechanism 200, the stretchable area 406 of the support 400 can stretch and bend, so that the pulling force on the bonding position of the support 400 and the screen support side plate is small, and thus the support 400 is not easy to fall off from the screen support side plate, thereby improving the reliability and safety of the foldable electronic device. In addition, the structure in this scheme also makes the foldable electronic device have less abnormal sound.

[0110] In the above embodiment, the stretchable area 406 can be a mesh structure. At this time, the mesh structure can be obtained by etching the support 400, so that the manufacturing process of the support 400 is simple and the cost is low.

[0114] Optionally, the positioning part 460 can be a positioning hole, and the positioning holes of the first filling layer 410, the support 400 and the second filling layer 430 are oppositely arranged, so as to position the assembly positions of the first filling layer 410, the support 400 and the second filling layer 430. Alternatively, the positioning part 460 can also be an identification part, such as a circular identification, a cross-shaped identification or the like, and the assembly positions of the first filling layer 410, the support 400 and the second filling layer 430 are positioned through the corresponding identification parts.
