Description

Technical Field

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

[0002] With the continuous development of flexible display technology, it is widely used in a variety of foldable electronic devices. Foldable electronic devices often include a shell device for carrying a flexible display. The shell device generally includes two middle frames and a folding device connected between the two shells. The two middle frames are relatively folded or unfolded under the drive of the folding device. Among them, in traditional screen-folding electronic devices, when the electronic device falls, the middle frame is locally collapsed and deformed by the impact force, affecting the normal use of the electronic device. Therefore, how to reduce the impact of the electronic device falling on the middle frame has become a research direction. Summary of the invention

[0003] The embodiments of the present application provide a foldable electronic device and a housing device, aiming to provide a housing device with a small amount of collapse of the middle frame when the electronic device falls, and an electronic device including the housing device.

[0004] In the first aspect, a housing device is provided. The housing device comprises a first middle frame, a second middle frame and a folding mechanism, wherein the folding mechanism connects the first middle frame and the second middle frame; the first middle frame comprises a first main body plate, a first extension plate, a second extension plate and a third extension plate. The first extension plate and the second extension plate are connected to the same side of the first main body plate close to the second middle frame, and are respectively located at both ends of the first main body plate along the length extension direction of the folding mechanism. The third extension plate is connected between the first extension plate and the second extension plate, and the third extension plate is also connected to the first main body plate. The first main body plate, the first extension plate, the second extension plate and the third extension plate surround a first mounting groove, and a part of the folding mechanism is arranged in the first mounting groove. The housing device also comprises a first stopper, wherein the length extension direction of the folding mechanism comprises a first end and a second end arranged oppositely, and the first stopper is located on the side of the first end facing away from the second end, and is fixedly connected to the folding mechanism. The housing device has an open state and a closed state. When the housing device is in the open state, the first middle frame and the second middle frame are relatively flattened, and the first stopper is arranged at intervals from the first contact surface, and the first contact surface is the surface of the first extension plate facing the second middle frame when the housing device is in the open state. When the shell device is in a closed state, the first middle frame and the second middle frame are folded relative to each other, and the distance between the first stopper and the first contact surface is less than or equal to 0.4 mm.

[0005] It can be understood that in this embodiment, a first stopper is arranged on the side of the first end of the folding mechanism facing away from the second end, and the first end and the second end are arranged in the length extension direction of the hinge structure. When the electronic device is in an open state, the first surface of the first stopper can be spaced from the first contact surface of the first extension plate of the first middle frame. When the electronic device is in a closed state, the first support surface of the first stopper is spaced from the first contact surface of the first extension plate, and the spacing between the two can be less than or equal to 0.4 mm. In this way, when the electronic device is in a closed state, the spacing between the first support surface of the first stopper and the first contact surface of the first extension plate is small, so that the first stopper can be used to support the first middle frame when the electronic device falls, thereby playing a stop role in the collapse of the first middle frame, so as to reduce the collapse amount of the first middle frame after falling and the deformation amount of the first middle frame, thereby reducing the probability of screen failure, which is conducive to improving the drop reliability of the electronic device and extending the service life of the electronic device. At the same time, compared with general electronic devices, by making the middle frame as a whole using high-strength materials, the collapse amount of the middle frame when falling is reduced, and the drop reliability of the electronic device is improved. However, the use of high-strength materials for the entire middle frame will greatly increase the weight of the middle frame and the manufacturing cost of the middle frame. In this embodiment, only by setting a first stopper on the side of the first end of the hinge structure facing away from the second end, and setting a distance between the first stopper and the first middle frame when the electronic device is in a closed state, the drop reliability of the electronic device can be effectively improved, thereby achieving an electronic device with lighter weight and lower manufacturing cost while meeting the drop reliability requirements of the electronic device itself.

[0006] Secondly, when the electronic device is in a closed state, the distance between the first stopper and the first middle frame is small, which can also effectively reduce the movement of the first middle frame when the electronic device falls, thereby avoiding the problem of the first middle frame pulling the screen and causing screen failure.

[0007] In a possible implementation, when the housing device is in a closed state, the distance between the first stopper and the first contact surface is greater than or equal to 0.1 mm. In this way, there is a certain distance between the first support surface of the first stopper and the first contact surface of the first middle frame, thereby effectively avoiding the problem of the first stopper and the first middle frame being scratched when the electronic device switches between the open state and the closed state.

[0008] In a possible implementation, when the shell device is in an open state, the spacing between the first contact surface and the first stopper is less than or equal to 0.4 mm. In this way, on the one hand, the spacing between the first stopper and the first surface and the first contact surface of the first extension plate is small, so that when the electronic device is in an open state and falls, the first stopper can still be used to support the first middle frame, thereby playing a stopper role for the collapse of the first middle frame, so as to reduce the amount of collapse and deformation of the first middle frame after falling. On the other hand, when the electronic device falls in an open state, even if the first middle frame is displaced, due to the small spacing between the first surface and the first contact surface, the amount of dislocation of the first middle frame caused by the fall is small, thereby effectively reducing the pulling of the screen by the dislocation of the first middle frame, so as to reduce the impact of the electronic device on the screen when it falls, which is conducive to extending the service life of the electronic device.

[0009] In a possible implementation, the first stopper includes a first part and a second part, the first part is fixed to a side of the first end of the folding structure facing away from the second end, and the second part is fixedly connected to a surface of the first part facing the first end. When the housing device is in an open state, the projection of the second part along the thickness direction of the housing device covers part of the folding mechanism, and the second part is spaced apart from the folding mechanism.

[0010] It can be understood that the first stopper in the present embodiment includes a first part and a second part, and the second part can be fixed to the surface of the first part facing the hinge structure to form an undercut structure. When the electronic device is in an open state, the second part can be located above the screen (that is, the light-emitting side of the screen) and spaced apart from the screen. In this way, the second part can also wrap the edge of the screen from above the screen to prevent the edge of the screen from being exposed to protect the bending portion, while also improving the appearance of the electronic device. In other words, the first stopper in the present embodiment can be used to support the first middle frame when the electronic device falls, so as to reduce the amount of collapse of the first middle frame when it falls, and improve the falling reliability of the electronic device. On the other hand, the first stopper can also be used to protect the edge of the screen and improve the appearance of the electronic device. The first stopper can achieve multiple uses of one object, which is conducive to reducing the number of parts of the electronic device, streamlining the structure, and effectively reducing the manufacturing cost and assembly difficulty of the electronic device.

[0011] In a possible implementation, the surface of the second part facing the folding mechanism is arc-shaped. Thus, compared to the first stopper whose first surface of the second part is a plane, the second part of the first stopper has a thinner overall thickness. In this embodiment, the first surface of the second part is arc-shaped, so that the thickness of the second part near the middle is thicker, thereby enhancing the strength of the second part and reducing the probability of the second part damaging the screen due to bending or deformation (for example, bending or deformation in the direction toward the screen) caused by collision, which is beneficial to extending the service life of the electronic device. At the same time, the first surface is arc-shaped, which is similar to the shape of the bent portion after deformation, so that while increasing the thickness of the second part, it is possible to avoid the second part rubbing against the screen, causing the problem of screen failure.

[0012] In a possible implementation, the folding mechanism includes a first connection structure, a second connection structure and a hinge structure, the hinge structure connects the first connection structure and the second connection structure, the first connection structure is arranged in the first mounting groove and connected to the first middle frame, the second connection structure is connected to the second middle frame, and the first stopper is fixedly connected to the hinge structure. In this way, the first stopper is fixedly connected to the hinge structure, and assembly is more convenient.

[0013] In a possible implementation, the first stopper is integrally formed with the hinge structure; or, a portion of the first stopper is embedded in the hinge structure. In this way, the connection reliability between the first stopper and the hinge structure is high, thereby effectively preventing the first stopper from falling off from the hinge structure due to a large impact force when supporting the first middle frame, which is beneficial to improving the overall structural stability of the electronic device and extending the service life of the electronic device. Among them, the integral formation of the first stopper and the hinge structure can also reduce the number of parts of the electronic device, thereby reducing the manufacturing cost and assembly difficulty of the electronic device and improving production efficiency.

[0014] In a possible implementation, the folding mechanism includes a first connection structure, a second connection structure, a hinge structure, and a decorative piece, the hinge structure connects the first connection structure and the second connection structure, the first connection structure is arranged in the first mounting groove and connected to the first middle frame, the second connection structure is connected to the second middle frame, the decorative piece is fixed to the outer side of the hinge structure, and the first stopper is fixedly connected to the decorative piece. In this way, the first stopper is fixedly connected to the decorative piece, and assembly is more convenient.

[0015] In a possible implementation, the first stopper is integrally formed with the decorative part; or, a part of the first stopper is embedded in the decorative part. In this way, the connection reliability between the first stopper and the decorative part is high, so that the problem of the first stopper falling off from the decorative part due to a large impact force when supporting the first middle frame can be effectively avoided, which is beneficial to improving the overall structural stability of the electronic device and extending the service life of the electronic device. Among them, the integral formation of the first stopper and the decorative part can also reduce the number of parts of the electronic device, thereby reducing the manufacturing cost and assembly difficulty of the electronic device and improving production efficiency. At the same time, compared with the integral formation of the first stopper and the hinge structure, the hinge structure has more structural features and the integrated forming process is more difficult. However, the first stopper and the decorative part are integrally formed, the decorative part has fewer structural features, and the integrated forming process is less difficult, which is beneficial to reducing the preparation difficulty and cost of the first stopper and improving the production efficiency of the electronic device.

[0016] In one possible implementation, the first extension plate includes a first main body portion and a first reinforcement portion, the first main body portion is fixedly connected to the first main plate and the third extension plate, the first reinforcement portion is fixed to the end of the first main body portion facing away from the first main plate, and the surface of the first reinforcement portion facing away from the first main plate constitutes at least a portion of the first contact surface.

[0017] It is understandable that the first extension plate in the present embodiment may include a first main body portion and a first reinforcement portion which are separately arranged. The first reinforcement portion may be fixed to the end of the first main body portion which faces away from the first main plate. The surface of the first reinforcement portion which faces away from the first main plate may constitute the first contact surface of the first extension plate. In this way, when the electronic device falls, the first reinforcement portion directly bears most of the impact force from the first stopper, thereby avoiding the problem that the rest of the first middle frame may be partially collapsed and deformed due to the greater impact force, thereby avoiding screen failure and helping to extend the service life of the electronic device.

[0018] In a possible implementation, a first assembly groove is provided at the end of the first main body portion facing away from the first main body plate, and at least a portion of the first reinforcement portion is located in the first assembly groove. In this way, at least a portion of the first reinforcement portion can be embedded in the first main body portion, thereby effectively preventing the first reinforcement portion from falling off from the first main body portion due to excessive impact force.

[0019] In the second aspect, a foldable electronic device is provided. The electronic device includes a screen and the above-mentioned housing device, and the screen is fixedly connected to the first middle frame and the second middle frame. It can be understood that in this embodiment, by setting a first stopper on the side of the first end of the folding mechanism facing away from the second end, the first end and the second end are arranged in the length extension direction of the hinge structure. When the electronic device is in an open state, the first surface of the first stopper can be spaced from the first contact surface of the first extension plate of the first middle frame. When the electronic device is in a closed state, the first support surface of the first stopper is spaced from the first contact surface of the first extension plate, and the spacing between the two can be less than or equal to 0.4 mm. In this way, when the electronic device is in a closed state, the spacing between the first support surface of the first stopper and the first contact surface of the first extension plate is small, so that the first stopper can be used to support the first middle frame when the electronic device falls, thereby playing a stopper role in the collapse of the first middle frame, so as to reduce the collapse amount of the first middle frame after falling and the deformation amount of the first middle frame, thereby reducing the probability of screen failure, which is conducive to improving the drop reliability of the electronic device and extending the service life of the electronic device. At the same time, compared with general electronic devices, the middle frame is made of high-strength materials to reduce the amount of collapse of the middle frame when it falls, thereby improving the drop reliability of the electronic device. However, the use of high-strength materials to make the middle frame as a whole will greatly increase the weight of the middle frame and the manufacturing cost of the middle frame. In this embodiment, only by setting a first stopper on the side of the first end of the hinge structure facing away from the second end, and setting the distance between the first stopper and the first middle frame when the electronic device is in a closed state, the drop reliability of the electronic device can be effectively improved, thereby meeting the drop reliability requirements of the electronic device itself, and obtaining an electronic device with lighter weight and lower manufacturing cost.

[0020] Secondly, when the electronic device is in a closed state, the distance between the first stopper and the first middle frame is small, which can also effectively reduce the movement of the first middle frame when the electronic device falls, thereby avoiding the problem of the first middle frame pulling the screen and causing screen failure.

[0021] In one possible implementation, the first stopper includes a first part and a second part, the first part is fixed to the side of the first end of the folding structure facing away from the second end, the second part is fixedly connected to the surface of the first part facing the first end, and the second part is located on the light emitting side of the screen and is spaced apart from the screen.

[0022] It can be understood that the first stopper in the present embodiment includes a first part and a second part, and the second part can be fixed to the surface of the first part facing the hinge structure to form an undercut structure. When the electronic device is in an open state, the second part can be located above the screen (that is, the light-emitting side of the screen) and spaced apart from the screen. In this way, the second part can also wrap the edge of the screen from above the screen to prevent the edge of the screen from being exposed to protect the bending portion, while also improving the appearance of the electronic device. In other words, the first stopper in the present embodiment can be used to support the first middle frame when the electronic device falls, so as to reduce the amount of collapse of the first middle frame when it falls, and improve the falling reliability of the electronic device. On the other hand, the first stopper can also be used to protect the edge of the screen and improve the appearance of the electronic device. The first stopper can achieve multiple uses of one object, which is conducive to reducing the number of parts of the electronic device, streamlining the structure, and effectively reducing the manufacturing cost and assembly difficulty of the electronic device.

[0023] In a possible implementation, when the housing device is in an open state, the distance between the second portion and the screen is in a range of 0.35 mm to 0.55 mm. In this way, the second portion can prevent the screen from being scratched by a hand and prevent dust and debris from entering the interior of the electronic device while preventing the bent portion from being exposed.

[0024] In a possible implementation, the first part is spaced apart from the screen, and the distance between the first part and the screen is in the range of 0.6 mm to 0.8 mm. In this way, the first part and the screen have a certain distance, so that when the electronic device falls, the screen can be prevented from moving and colliding with the first part, causing the screen to fail, which is conducive to extending the service life of the electronic device.

[0043] The embodiments of the present application are described below in conjunction with the accompanying drawings in the embodiments of the present application.

[0044] In the description of the implementation mode of the present application, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed connection" means that the two are connected to each other and the relative position relationship after the connection remains unchanged. The directional terms mentioned in the implementation mode of the present application, such as "upper", "lower", "inner", "outer", etc., are only referenced to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the implementation mode of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the implementation mode of the present application. "Multiple" means at least two.

[0045] In the embodiments of the present application, the terms "first", "second", "third", and "fourth" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first", "second", "third", and "fourth" may explicitly or implicitly include one or more of the features.

[0046] In the implementation manner of the present application, "and / or" is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0047] References to "one embodiment" or "some embodiments" etc. described in this specification mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in another embodiment", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0048] It is to be understood that the specific implementations described herein are only used to explain the relevant invention, rather than to limit the invention. It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings.

[0049] Figure 1 It is a schematic diagram of the structure of the electronic device 1000 provided in an embodiment of the present application when it is in an open state. Figure 2 yes Figure 1 The structure diagram of the electronic device 1000 shown is in a closed state. Figure 3 yes Figure 1 The illustrated electronic device 1000 is a schematic diagram of a partially exploded structure in some implementations.

[0050] like Figures 1 to 3 As shown, the electronic device 1000 may include a housing device 100 and a screen 200. The screen 200 may be mounted on the housing device 100. The housing device 100 may be in a Figure 1 The open state shown, and Figure 1 The housing device 100 may also be in an intermediate state between unfolding or folding. The intermediate state may be any state between the open state and the closed state. The screen 200 may move together with the housing device 100. The housing device 100 may drive the screen 200 to unfold or fold, so that the electronic device 1000 may be unfolded to an open state, or folded to a closed state. When the electronic device 1000 is in a closed state, the screen 200 may be located on the inner side of the housing device 100. In other words, the electronic device 1000 may be an electronic device with an inner folding screen. It should be understood that Figures 1 to 3 Only some components of the electronic device 1000 are schematically shown, and the actual shapes, sizes and structures of these components are not limited to the following. Figure 1 , Figure 2 and Figure 3 In other implementations, when the electronic device 1000 is a device in another form factor, the electronic device 1000 may not include the screen 200 .

[0051] In this embodiment, when the electronic device 1000 is in an open state, the screen 200 can be flattened. At this time, the screen 200 can be displayed in full screen, and the electronic device 1000 has a large display area, which is conducive to improving the user's viewing experience and operation experience. When the electronic device 1000 is in a closed state, the plane size of the electronic device 1000 is small, which is convenient for the user to carry and store.

[0052] For example, in combination Figures 1 to 3 and Figure 8, the housing device 100 may include a first housing 10, a second housing 20, a folding mechanism 30, a first stopper 40 and a second stopper 50. The folding mechanism 30 may connect the first housing 10 and the second housing 20. The first stopper 40 and the second stopper 50 may be fixedly connected to the folding mechanism 30. The folding mechanism 30 may move so that the first housing 10 and the second housing 20 can be relatively unfolded to an open state, or relatively folded to a closed state. The screen 200 may be fixedly connected to the first housing 10 and the second housing 20. Among them, the first housing 10 may include a first middle frame 11 and a first back cover 12. The first back cover 12 may be located on the side of the first middle frame 11 facing away from the screen 200, and is fixedly connected to the first middle frame 11. The second housing 20 may include a second middle frame 21 and a second back cover 22. The second back cover 22 may be located on the side of the second middle frame 21 facing away from the screen 200, and is fixedly connected to the second middle frame 21. At this time, the surface of the first back cover 12 facing away from the first middle frame 11 may constitute the appearance surface of the first housing 10. The surface of the second back cover 22 facing away from the second middle frame 21 can constitute the outer surface of the second shell 20. It should be understood that the first shell 10 and the second shell 20 are both shell parts, which are used to install and fix other components of the electronic device and have a variety of structures. The folding mechanism 30 is used to achieve relative movement between the first shell 10 and the second shell 20, and also has a variety of structures. The embodiments of the present application do not strictly limit the specific structures of the first shell 10, the second shell 20 and the folding mechanism 30. The drawings of the present application only illustrate the general structure of the first shell 10, the second shell 20 and the folding mechanism 30 in one embodiment.

[0053] Exemplarily, the screen 200 may be integrated with a display function and a touch sensing function. The display function of the screen 200 is used to display images, videos, etc., and the touch sensing function of the screen 200 is used to sense the user's touch action to achieve human-computer interaction. Exemplarily, the screen 200 includes a flexible display screen that can be bent. Among them, the flexible display screen can use a liquid crystal display (LCD), an organic light-emitting diode (OLED) display screen, an active matrix organic light-emitting diode or an active matrix organic light-emitting diode (AMOLED) display screen, a flexible light-emitting diode (FLED) display screen, a MiniLED display screen, a MicroLED display screen, a Micro-OLED display screen, a quantum dot light emitting diode (QLED) display screen, etc.

[0054] The screen 200 may include a first non-bending portion 201, a bending portion 202, and a second non-bending portion 203 arranged in sequence. The first non-bending portion 201 may be fixed to the first shell 10. The second non-bending portion 203 may be fixed to the second shell 20. During the relative folding or unfolding of the first shell 10 and the second shell 20, the bending portion 202 of the screen 200 may be deformed. For ease of understanding, the direction that is the same as the light emitting direction of the screen 200 is "up", and the direction opposite to the light emitting direction of the screen 200 is "down".

[0055] Exemplarily, the electronic device 1000 may further include multiple components (not shown in the figure), and the multiple components are installed inside the housing device 100. The multiple components may include, for example, a processor, an internal memory, an external memory interface, a universal serial bus (USB) interface, a charging management module, a power management module, a battery, an antenna, a communication module, a camera, an audio module, a speaker, a receiver, a microphone, an earphone interface, a sensor module, a button, a motor, an indicator, and a subscriber identification module (SIM) card interface.

[0056] In this embodiment, the electronic device 1000 is taken as an example of a two-fold structure, that is, the electronic device 1000 includes two flat plate parts and a bending portion 202 connected between the two flat plate parts. Among them, the two flat plate parts can be rotated toward each other to overlap each other (corresponding to the closed state in the previous text), so that the electronic device 1000 presents a two-layer form; the two flat plate parts can also be rotated away from each other to be flattened (corresponding to the open state in the previous text). In other embodiments, the electronic device 1000 can also be a structure of more than three folds, that is, the electronic device 1000 includes more than three flat plate parts, and two adjacent flat plate parts are connected by the bending portion 202, and the two adjacent flat plates can be relatively rotated to overlap each other or rotated away from each other to be flattened. When the electronic device 1000 is a structure of more than three folds, the structure of the electronic device 1000 can refer to the description of the two-fold structure of this embodiment for adaptive design, and this application will not repeat it.

[0057] Figure 4 yes Figure 3 The structural schematic diagram of the housing device 100 is shown. Figure 5 yes Figure 3 FIG. 1 is a schematic diagram of a partially exploded structure of the housing device 100 . Figure 6 yes Figure 5 The first middle frame 11 is a schematic diagram of the exploded structure in some embodiments. It should be noted that, in order to simplify the diagram, Figure 5Only the structures of the first middle frame 11, the second middle frame 21 and the folding mechanism 30 are shown.

[0058] like Figures 4 to 6 As shown, the first middle frame 11 may include a first main body plate 111, a first extension plate 112, a second extension plate 113 and a third extension plate 114. The first extension plate 112 and the second extension plate 113 may be connected to the same side of the first main body plate 111 close to the second middle frame 21, and are respectively located at both ends of the first main body plate 111 along the length extension direction of the folding mechanism 30. The third extension plate 114 may be connected between the first extension plate 112 and the second extension plate 113.

The first contact surface 112a and the second contact surface 113a can both face the second middle frame 21. It should be understood that although the first middle frame 11 is divided into four parts for introduction in this embodiment, it does not affect the fact that the first middle frame 11 can be an integrally formed structure, that is, the first main body plate 111, the first extension plate 112, the second extension plate 113 and the third extension plate 114 can be integrally formed.

[0060] Exemplarily, the first extension plate 112 of the first middle frame 11 may include a first main body portion 1121 and a first reinforcement portion 1122.

[0063] Figure 7 yes Figure 5 The illustrated schematic diagram is a schematic diagram of the exploded structure of the second middle frame 21 in some embodiments.

The third contact surface 212a and the fourth contact surface 213a can both face the first middle frame 11.

Among them, the end of the third main body portion 2121 facing away from the second main body plate 211 may be provided with a third assembly groove 2123. The opening of the third assembly groove 2123 may be formed on the surface of the third main body portion 2121 facing away from the second main body plate 211 and the surface of the third main body portion 2121 facing the fifth extension plate 213. At least a portion of the third reinforcing portion 2122 may be located in the third assembly groove 2123 and fixedly connected to the third main body portion 2121. In other embodiments, the third main body portion 2121 may not be provided with the third assembly groove 2123.

The fourth main body portion 2131 may be fixedly connected to the second main body plate 211 and the sixth extension plate 214.

[0068] In some other embodiments, the fourth extension plate 212 may not include the fourth reinforcement portion 2132 . The fifth extension plate 213 may not include the fifth reinforcement portion 2123 .

[0069] Figure 8 yes Figure 5 The illustrated diagram is a schematic diagram of the assembly structure of the folding mechanism 30 , the first stopper 40 , and the second stopper 50 in some embodiments.

[0070] like Figure 8 As shown, the folding mechanism 30 may include a first connection structure 31, a second connection structure 32, a hinge structure 33 and a decorative member 34. The first connection structure 31 and the second connection structure 32 may be substantially symmetrical structures. Both the first connection structure 31 and the second connection structure 32 may be connected to the hinge structure 33. Both the first connection structure 31 and the second connection structure 32 may move relative to the hinge structure 33. The decorative member 34 may be fixed to the hinge structure 33. In this way, the decorative member 34 may prevent the hinge structure 33 from being exposed, thereby protecting the hinge structure 33. At the same time, the surface of the decorative member 34 facing away from the hinge structure 33 may constitute a part of the appearance surface of the electronic device 1000, so that the electronic device 1000 has a better appearance effect. In other embodiments, the folding mechanism 30 may also not include the decorative member 34.

[0071] Exemplarily, the folding mechanism 30 may include a first end 30a and a second end 30b in the direction of its length extension. The first stopper 40 may be located on the side of the first end 30a facing away from the second end 30b. Among them, the first stopper 40 may be fixedly connected to the hinge structure 33. Exemplarily, the first stopper 40 and the hinge structure 33 may be integrally formed, that is, the first stopper 40 and the hinge structure 33 may be an integrally formed structure. Alternatively, a portion of the first stopper 40 may also be embedded in the hinge structure 33. For example, a protrusion may be provided on the surface of the first stopper 40 facing the hinge structure 33 (not shown). The surface of the hinge structure 33 facing the first stopper may be partially recessed inward to form a groove (not shown). The protrusion of the first stopper 40 may be fixed in the groove of the hinge structure 33. In this way, the connection reliability of the first stopper 40 and the hinge structure 33 is high. In other embodiments, the first stopper 40 may also be fixedly connected to the surface of the first end 30a facing away from the second end 30b by bonding, screwing, welding, etc.

[0072] For example, the second stopper 50 may be located at a side of the second end 30b facing away from the first end 30a. The second stopper 50 may be fixedly connected to the hinge structure 33. For example, the second stopper 50 and the second end 30b may be integrally formed, that is, the second stopper 50 and the hinge structure 33 may be an integrally formed structure. Of course, in other embodiments, the second stopper 50 may also be fixedly connected to the surface of the second end 30b facing away from the first end 30a by bonding, screwing, welding, etc.

[0073] Figure 9a yes Figure 1 The illustrated diagram is a partial cross-sectional structural diagram of an electronic device 1000 in one embodiment cut along AA. Figure 9b yes Figure 2 The illustrated diagram is a partial cross-sectional structural diagram of an electronic device 1000 in one embodiment cut along line BB. Fig.10 yes Figure 5 The first middle frame 11, the second middle frame 21 and the first stopper 40 are partially assembled. Figure 9b The hinge structure 33 and the first stopper 40 are schematically divided by a dotted line.

[0074] like Figures 9a to 10 As shown, at least a portion of the first connection structure 31 of the folding mechanism 30 may be located in the first mounting groove 11a of the first middle frame 11, and connected to the first middle frame 11. At least a portion of the second connection structure 32 of the folding mechanism 30 may be located in the second mounting groove 21a of the second middle frame 21, and connected to the second middle frame 21. A portion of the hinge structure 33 of the folding mechanism 30 may be located in the first mounting groove 11a, and a portion of the hinge structure 33 may be located in the second mounting groove 21a.

[0075] For example, when the electronic device 1000 is in an open state (that is, when the housing device 100 is in an open state), the first stopper 40 may be located between the first contact surface 112a of the first extension plate 112 of the first middle frame 11 and the third contact surface 212a of the fourth extension plate 212 of the second middle frame 21 ( Figure 4The relative positional relationship between the first stopper 40 and the first contact surface 112a and the third contact surface 212a is also illustrated. At this time, the surface of the first stopper 40 facing the first extension plate 112 is the first surface 41. The surface of the first stopper 40 facing the fourth extension plate 212 is the second surface 42. The upper surface of the first stopper 40 is the first supporting surface 43, that is, the surface of the first stopper 40 facing the light-emitting side of the screen 200 is the first supporting surface 43. The first supporting surface 43 can be connected between the first surface 41 and the second surface 42. Among them, the first surface 41 of the first stopper 40 can be spaced apart from the first contact surface 112a of the first extension plate 112. The second surface 42 of the first stopper 40 can be spaced apart from the third contact surface 212a of the fourth extension plate 212.

[0076] It should be noted that the relative positional relationship between the second stopper 50 and the second contact surface 113a of the first middle frame 11 and the fourth contact surface 213a of the second middle frame 21 can refer to the description of the relative positional relationship between the first stopper 40 and the first middle frame 11 and the second middle frame 21, and Figure 4 The relative positional relationship between the second stopper 50 and the second contact surface 113a and the fourth contact surface 213a is also illustrated, which will not be repeated here.

[0077] Fig.11 yes Figure 2 The illustrated diagram is a partial cross-sectional structural diagram of an electronic device 1000 in one embodiment cut along line BB. Fig.12 yes Figure 2 The illustrated diagram is a partial cross-sectional structural diagram of an electronic device 1000 in one embodiment cut along CC.

[0078] like Fig.11 and Fig.12 As shown, when the electronic device 1000 is in a closed state, the first middle frame 11 and the second middle frame 21 can be folded relative to each other. The first connection structure 31 and the second connection structure 32 of the folding mechanism 30 can be folded relative to each other. At this time, the space between the first middle frame 11 and the second middle frame 21, and the space between the first connection structure 31 and the second connection structure 32 can be used to accommodate the screen 200.

[0079] Exemplarily, when the electronic device 1000 is in a closed state, the first support surface 43 of the first stopper 40 can be spaced apart from the first contact surface 112a of the first extension plate 112. The first support surface 43 of the first stopper 40 can also be spaced apart from the third contact surface 212a of the fourth extension plate 212. Among them, the spacing between the first support surface 43 and the first contact surface 112a can be less than or equal to 0.4 mm. The spacing between the first support surface 43 and the third contact surface 212a can also be less than or equal to 0.4 mm. In other embodiments, the spacing between the first support surface 43 and the first contact surface 112a can also be other values ​​greater than 0.4 mm. It should be understood that the spacing between the first support surface 43 and the first contact surface 112a refers to the minimum spacing between the first support surface 43 and the first contact surface 112a in the arrangement direction of the two, that is, the spacing between the area of ​​the first support surface 43 closest to the first contact surface 112a and the first contact surface 112a in the arrangement direction of the two. The distance between the first support surface 43 and the third contact surface 212a is the same as the above definition, which will not be repeated here. The distance between the two components can refer to the above explanation unless otherwise specified.

[0080] It can be understood that in this embodiment, the first stopper 40 is arranged on the side of the first end 30a of the folding mechanism 30 facing away from the second end 30b, and the first end 30a and the second end 30b are arranged in the length extension direction of the hinge structure 33. When the electronic device 1000 is in the open state, the first surface 41 of the first stopper 40 can be spaced apart from the first contact surface 112a of the first extension plate 112 of the first middle frame 11. When the electronic device 1000 is in the closed state, the first support surface 43 of the first stopper 40 is spaced apart from the first contact surface 112a of the first extension plate 112, and the distance between the two can be less than or equal to 0.4 mm. In this way, when the electronic device 1000 is in a closed state, the distance between the first support surface 43 of the first stopper 40 and the first contact surface 112a of the first extension plate 112 is small, so that the first stopper 40 can be used to support the first middle frame 11 when the electronic device 1000 falls, thereby playing a stop role in the collapse of the first middle frame 11, so as to reduce the collapse amount of the first middle frame 11 after falling and the deformation amount of the first middle frame 11, thereby reducing the probability of failure of the screen 200, which is conducive to improving the drop reliability of the electronic device 1000 and extending the service life of the electronic device 1000. At the same time, compared with general electronic devices, by making the middle frame as a whole adopting high-strength materials to prepare, the collapse amount of the middle frame when falling is reduced, and the drop reliability of the electronic device is improved. However, making the middle frame as a whole adopting high-strength materials will greatly increase the weight of the middle frame and the manufacturing cost of the middle frame. In the present embodiment, by merely setting the first stopper 40 on the side of the first end 30a of the hinge structure 33 facing away from the second end 30b, and setting the distance between the first stopper 40 and the first middle frame 11 when the electronic device 1000 is in a closed state, the drop reliability of the electronic device 1000 can be effectively improved, thereby achieving an electronic device 1000 with a lighter weight and a lower manufacturing cost while meeting the drop reliability requirements of the electronic device 1000 itself.

[0081] Secondly, when the electronic device 1000 is in a closed state, the distance between the first stop block 40 and the first middle frame 11 is small, which can also effectively reduce the movement of the first middle frame 11 when the electronic device 1000 falls, thereby avoiding the problem that the first middle frame 11 pulls the screen 200 and causes the screen 200 to fail.

[0082] In addition, the first stopper 40 in this embodiment can be integrally formed with the hinge structure 33 of the folding mechanism 30, or a portion of the first stopper 40 can be embedded in the hinge structure 33 of the folding mechanism 30. In this way, the connection reliability between the first stopper 40 and the hinge structure 33 is high, thereby effectively avoiding the problem that the first stopper 40 falls off from the hinge structure 33 due to a large impact force when supporting the first middle frame 11, which is beneficial to improving the overall structural stability of the electronic device 1000 and extending the service life of the electronic device 1000. Among them, the integral formation of the first stopper 40 and the hinge structure 33 can also reduce the number of parts of the electronic device 1000, thereby reducing the manufacturing cost and assembly difficulty of the electronic device 1000 and improving production efficiency.

[0083] In addition, the first extension plate 112 in the present embodiment may include a first main body portion 1121 and a first reinforcement portion 1122 which are separately arranged. The first reinforcement portion 1122 may be fixed to the end of the first main body portion 1121 which faces away from the first main plate 111. The surface of the first reinforcement portion 1122 which faces away from the first main plate 111 may constitute the first contact surface 112a of the first extension plate 112. In this way, when the electronic device 1000 falls, the first reinforcement portion 1122 directly bears most of the impact force from the first stopper 40, thereby avoiding the problem that the rest of the first middle frame 11 is locally collapsed and deformed due to the large impact force, avoiding failure of the screen 200, and helping to extend the service life of the electronic device 1000.

[0084] In some embodiments, the first reinforcement part 1122 can be prepared by 3D printing, metal injection molding, etc. The material of the first reinforcement part 1122 can be different from the material of the first middle frame 11. For example, the material of the first reinforcement part 1122 can be a material with higher strength such as a titanium alloy material, an iron-based material, an aluminum-based material, a copper-based material, and a nickel-based material. The strength of the first reinforcement part 1122 can be greater than the strength of the first main body 1121. In this way, the strength of the first reinforcement part 1122 is relatively large. When the electronic device 1000 falls, the first reinforcement part 1122 can better withstand the impact force of the first stopper 40 from the folding mechanism 30, thereby effectively avoiding the first stopper 40 and the adjacent part of the first middle frame 11 (that is, the first extension plate 112 in this embodiment) The impact force generated by the collision is too large, which causes the first middle frame 11 to collapse locally and deform, which is conducive to extending the service life of the electronic device 1000.

[0085] Secondly, compared with some electronic devices that use high-strength materials to prepare the first middle frame to improve the overall strength of the first middle frame. However, the use of high-strength materials to prepare the first middle frame as a whole also greatly increases the weight and manufacturing cost of the first middle frame. In this embodiment, the strength of the portion of the first middle frame 11 adjacent to the first stopper 40 is only enhanced (in this embodiment, the first reinforcement portion 1122 of the first extension plate 112), so there is no need to replace the entire material of the first middle frame 11 with high-strength materials. The overall weight of the first middle frame 11 is relatively light, which is conducive to realizing the lightweight setting of the electronic device 1000. At the same time, the manufacturing cost of the first middle frame 11 is relatively low, which is conducive to reducing the manufacturing cost of the entire electronic device 1000.

[0086] In some embodiments, when the electronic device 1000 is in the open state, the distance between the first surface 41 of the first stopper 40 and the first contact surface 112a of the first extension plate 112 of the first middle frame 11 can be less than or equal to 0.4 mm. In this way, on the one hand, the distance between the first surface 41 of the first stopper 40 and the first contact surface 112a of the first extension plate 112 is small, so that when the electronic device 1000 is in the open state and falls, the first stopper 40 can still be used to support the first middle frame 11, thereby playing a role in stopping the collapse of the first middle frame 11, so as to reduce the amount of collapse and deformation of the first middle frame 11 after falling. On the other hand, when the electronic device 1000 falls in the open state, even if the first middle frame 11 is displaced, since the distance between the first surface 41 and the first contact surface 112a is small, the displacement of the first middle frame 11 due to the fall is small, thereby effectively reducing the pulling of the screen 200 by the displacement of the first middle frame 11, thereby reducing the impact of the electronic device 1000 on the screen 200 when it falls, which is beneficial to extend the service life of the electronic device 1000.

[0087] In some embodiments, when the electronic device 1000 is in the closed state, the distance between the first support surface 43 of the first stopper 40 and the first contact surface 112a of the first middle frame 11 may be greater than or equal to 0.1 mm, thereby effectively avoiding the problem of the first stopper 40 and the first middle frame 11 being scratched when the electronic device 1000 is switched between the open state and the closed state. In some other embodiments, when the electronic device 1000 is in the open state, the distance between the first surface 41 of the first stopper 40 and the first contact surface 112a of the first middle frame 11 may be greater than or equal to 0.1 mm.

[0088] The above specifically introduces the relative positional relationship between the first stopper 40 and other components in the electronic device 1000 . The following will introduce the specific structure of the first stopper 40 in conjunction with the relevant drawings.

[0089] Fig.13 yes Figure 8 The illustrated structure of the first stopper 40 of the folding mechanism 30 in some embodiments. Fig.14 yes Figure 9b The structure shown is a schematic diagram of the enlarged structure at D. Fig.15 yes Figure 2 The illustrated diagram is a partial cross-sectional structural diagram of an electronic device 1000 in one embodiment cut along EE.

[0090] like Figures 13 to 15 As shown, the first stopper 40 may include a first portion 44 and a second portion 45. For ease of understanding, Fig.13 and Fig.14 The first portion 44 and the second portion 45 are schematically divided by a narrow dotted line. The first portion 44 may be located on the side of the first end 30a of the folding mechanism 30 that faces away from the second end 30b. The first portion 44 may be fixedly connected to the hinge structure 33. When the electronic device 1000 is in the open state, the surface of the first portion 44 facing the first extension plate 112 may constitute the first surface 41 of the first stopper 40. The surface of the first portion 44 facing the fourth extension plate 212 may constitute the second surface 42 of the first stopper 40 (please refer to FIG. 1 for details). Fig.10 The distance between the surface of the first portion 44 facing the hinge structure 33 and the screen 200 may be in the range of 0.6 mm to 0.8 mm.

[0091] Exemplarily, the second portion 45 may be fixedly connected to the surface of the first portion 44 facing the hinge structure 33. When the electronic device 1000 is in the open state, the second portion 45 may cover part of the hinge structure 33 when projected along the thickness direction of the electronic device 1000. The second portion 45 may be spaced apart from the hinge structure 33. At this time, the second portion 45 may form an inverted hook structure relative to the first portion 44. The second portion 45 may include a first surface 451 and a second surface 452 that are disposed opposite to each other. When the electronic device 1000 is in the open state, the first surface 451 of the second portion 45 may face the hinge structure 33 and be spaced apart from the bending portion 202 of the screen 200. That is, the second portion 45 may be located on the light emitting side of the screen 200.

[0092] For example, the first surface 451 may be substantially arc-shaped. The distance between the first surface 451 of the second portion 45 and the bent portion 202 of the screen 200 may be in a range of 0.35 mm to 0.55 mm.

[0093] Exemplarily, when the electronic device 1000 is in a closed state, the surface of the first portion 44 facing the first contact surface 112a of the first extension plate 112 is the third surface 441. The second surface 452 of the second portion 45 may face the first contact surface 112a of the first extension plate 112. The second surface 452 and the third surface 441 may both be spaced apart from the first contact surface 112a of the first extension plate 112, and spaced apart from the third contact surface 212a of the second extension plate 113. The second surface 452 and the third surface 441 may together constitute the first support surface 43 of the first stopper 40. The bent portion 202 of the screen 200 may be deformed and bent. The shape of the first surface 451 of the second portion 45 may be adapted to the shape of the deformed bent portion 202 of the screen 200. In other words, the shape of the first surface 451 of the second portion 45 can be designed according to the bending radius of the bending portion 202 of the screen 200 so that the shape of the first surface 451 matches the shape of the bent portion 202 after bending.

[0094] It can be understood that the first stopper 40 in this embodiment includes a first part 44 and a second part 45, and the second part 45 can be fixed to the surface of the first part 44 facing the hinge structure 33 to form an undercut structure. When the electronic device 1000 is in an open state, the second part 45 can be located above the bending portion 202 of the screen 200 (that is, the light-emitting side of the screen 200), and is spaced apart from the bending portion 202 of the screen 200. In this way, the second part 45 can also wrap the edge of the bending portion 202 from above the bending portion 202 of the screen 200 to avoid the edge of the bending portion 202 from being exposed, so as to protect the bending portion 202, and at the same time, the appearance of the electronic device 1000 can also be improved. In other words, the first stopper 40 in this embodiment can be used to support the first middle frame 11 when the electronic device 1000 falls, so as to reduce the amount of collapse of the first middle frame 11 when it falls, and improve the falling reliability of the electronic device 1000. On the other hand, the first stopper 40 can also be used to protect the edge of the screen 200 and improve the appearance of the electronic device 1000. The first stopper 40 can achieve multiple uses, which is beneficial to reduce the number of parts of the electronic device 1000, simplify the structure, and effectively reduce the manufacturing cost and assembly difficulty of the electronic device 1000.

[0095] Secondly, the distance between the surface of the first part 44 facing the hinge structure 33 and the screen 200 can be in the range of 0.6 mm to 0.8 mm, thereby preventing the screen 200 from shifting and colliding with the first part 44 when the electronic device 1000 falls, causing the screen 200 to fail, which is beneficial to extending the service life of the electronic device 1000.

[0096] In addition, the surface of the second part 45 facing the screen 200 may be arc-shaped. Thus, compared with the first surface of the second part being a plane, the second part of the first stopper is a first stopper with a thinner overall thickness. In this embodiment, the first surface 451 of the second part 45 is arc-shaped, so that the thickness of the portion of the second part 45 close to the middle thereof is thicker, thereby enhancing the strength of the second part 45, reducing the probability of the second part 45 being bent or deformed (for example, bent or deformed in the direction toward the screen 200) due to collision and damaging the screen 200, and helping to extend the service life of the electronic device 1000. At the same time, the first surface 451 is arc-shaped, similar to the shape of the bent portion 202 after deformation, so that the second part 45 can be prevented from rubbing against the screen 200 while increasing the thickness of the second part 45, resulting in failure of the screen 200. In some embodiments, the shape of the first surface 451 of the second part 45 can be adapted to the shape of the bent portion 202 after deformation.

[0097] In addition, when the electronic device 1000 is in the open state, the distance between the first surface 451 of the second part 45 and the bent portion 202 of the screen 200 can be in the range of 0.35 mm to 0.55 mm, thereby preventing the bent portion 202 from being exposed while preventing people from scratching the screen and preventing external dust and debris from entering the interior of the electronic device 1000.

[0098] In other embodiments, only the second surface 452 of the second portion 45 may constitute the first contact surface 112 a of the first stopper 40 . Alternatively, only the third surface 441 of the first portion 44 may constitute the first contact surface 112 a of the first stopper 40 .

[0099] Fig.16 yes Figure 9b The structure shown is a schematic diagram of the structure in another embodiment.

[0100] like Fig.16 As shown, the structure of the electronic device 1000 in this embodiment is similar to Figure 9b The structure of the electronic device 1000 shown is substantially the same, and the same parts are not repeated. The difference is that the first stopper 40 can be located at the first end 30a of the hinge structure 33 facing away from the second end 30b (please refer to Figure 8 As shown in the figure, the first stopper 40 is fixedly connected to the decorative member 34. For example, the first stopper 40 can be integrally formed with the decorative member 34. For ease of understanding, Fig.15The dotted lines schematically divide the decorative piece 34 and the first stopper 40. Thus, compared with the first stopper 40 being integrally formed with the hinge structure 33, the hinge structure 33 has more structural features and the integral forming process is more difficult. In this embodiment, the first stopper 40 can be directly integrally formed with the decorative piece 34, the decorative piece 34 has fewer structural features, and the integral forming process is less difficult, which is conducive to reducing the difficulty and cost of preparing the first stopper 40 and improving the production efficiency of the electronic device 1000.

[0101] In other embodiments, the first stopper 40 may not be integrally formed with the decorative component 34 , and a portion of the first stopper 40 may be embedded in the decorative component 34 .

[0102] It should be noted that, in the absence of conflict, the features in the embodiments of the present application can be combined with each other, and any combination of features in different embodiments is also within the protection scope of the present application. That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0103] It should be noted that all the above drawings are illustrative illustrations of the present application and do not represent the actual size of the product.
