[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on July 31, 2023, with application number 202310961668.1, and priority to the Chinese patent application entitled “Foldable electronic device and screen assembly”, all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of foldable electronic products, and in particular to a foldable electronic device and a screen assembly. Background Art

[0003] With the continuous development of flexible display technology, it is widely used in a variety of foldable electronic devices. Among them, electronic devices with foldable screens are popular among users due to their greater convenience. However, whether the screen is open or closed, the screen of these electronic devices is exposed to the external environment, greatly increasing the probability of screen damage if the electronic device is dropped.

[0004] Traditional foldable electronic devices typically sacrifice screen thickness to improve drop resistance. However, while increasing screen thickness improves drop resistance, it also significantly increases the rebound force when the screen is bent, resulting in a poor opening and closing experience. Current research focuses on developing electronic devices with both high drop resistance and low rebound force.

[0005] Summary of the Invention

[0006] The embodiments of the present application provide a foldable electronic device, aiming to provide a foldable electronic device and a screen assembly with high screen drop reliability and small rebound force.

[0007] In a first aspect, a foldable electronic device is provided. The electronic device includes a screen, a hinge assembly, a first housing, a second housing, and an elastic assembly. The screen is fixedly connected to the first and second housings. The hinge assembly includes a first connecting portion, a second connecting portion, and a main shaft portion. The shaft portion connects the first and second connecting portions. The first connecting portion is connected to the first housing. The second connecting portion is connected to the second housing. The elastic assembly includes an elastic portion and a support portion. The elastic portion is made of an elastic material or a non-Newtonian fluid material. The support portion is made of a rigid material. The electronic device has an open state and a closed state. When the electronic device is in the open state, the elastic assembly flattens. The screen, the elastic assembly, and the hinge assembly are stacked along the thickness of the electronic device. The elastic portion and the support portion are stacked along the thickness of the electronic device. The first portion of the elastic assembly overlaps the first connecting portion, and the second portion overlaps the second connecting portion. When the electronic device is in the closed state, the elastic assembly bends, with the first portion overlapping the first connecting portion and the second portion overlapping the second connecting portion.

[0008] It is understandable that, compared to conventional electronic devices that sacrifice screen thickness to improve the overall structural reliability of the screen, resulting in a thicker overall thickness and greater rebound force when bent, the electronic device of this embodiment incorporates an elastic component between the screen and the main axis of the hinge assembly. The elastic component may include a supporting portion and an elastic portion. The supporting portion may be made of a rigid material, while the elastic portion may be made of an elastic material or a non-Newtonian fluid. When the electronic device is in the open state, the screen, elastic component, and hinge assembly are stacked along the thickness of the electronic device. This allows the supporting portion of the elastic component to effectively absorb the impact and / or compressive force exerted by the hinge assembly on the screen, reducing the impact force and providing good rigid support for the screen. The elastic portion of the elastic component provides a good elastic effect on the impact and / or compressive force exerted on the screen, while also absorbing and dissipating the impact and / or compressive force exerted on the screen. The elastic component effectively absorbs the impact of a drop, preventing the screen from experiencing bright spots and dark spots due to strong collisions with the hinge assembly. This helps improve the structural reliability of the screen and prolongs its lifespan. In other words, the screen in this embodiment does not sacrifice its thickness; the elastic component located between the screen and the hinge assembly effectively improves the screen's reliability in the event of a drop. Furthermore, the thinner overall thickness of the screen effectively reduces the rebound force when the electronic device is bent, improving the user's opening and closing experience.

[0009] In one possible implementation, the supporting portion includes a first supporting member. The elastic portion includes a first elastic member. The first supporting member is fixedly connected to the main shaft portion of the rotating shaft assembly. The first elastic member is fixedly connected to the surface of the first supporting member facing away from the main shaft portion. The first supporting member includes a first portion, a second portion, and a third portion. The second portion is connected between the first portion and the third portion. The second portion is fixedly connected to the main shaft portion. When the electronic device is in an open state, the first portion overlaps the first connecting portion and can move relative to the first connecting portion. The second portion is relatively flattened with the first portion, and the third portion overlaps the second connecting portion and can move relative to the second connecting portion.

[0010] It will be appreciated that the support portion of the elastic assembly in this embodiment may include at least one support member (also referred to as the first support member in this embodiment). The elastic portion of the elastic assembly may include at least one elastic member (also referred to as the first elastic member in this embodiment). The first support member may be made of a rigid material, and the first elastic member may be made of an elastic material or a non-Newtonian fluid. In this way, when the electronic device falls and the second portion of the screen is impacted, the first support member can effectively absorb the impact and / or compressive force exerted by the hinge assembly on the second portion of the screen, reducing the impact force on the screen and providing good rigid support for the screen. The first elastic member can effectively elastically resist the impact and / or compressive force exerted on the screen, while also absorbing and dissipating the impact and / or compressive force exerted on the screen. In other words, the elastic assembly in this embodiment includes both the first support member and the first elastic member, which respectively provide good rigid and elastic protection for the screen. The entire elastic assembly has strong impact and compressive resistance, enabling the elastic assembly to effectively protect the screen, improve the screen's drop reliability, and extend the screen's service life.

[0011] In one possible implementation, when the electronic device is in a closed state, the first part overlaps the first connecting part, the second part is bent, and the third part overlaps the second connecting part. When the electronic device switches from an open state to a closed state, the first part moves relative to the first connecting part, the second part is bent relative to the first part, and the third part moves relative to the second connecting part. In this way, whether the electronic device in this embodiment is in an open state or a closed state, the first support member can cover the gap between the main shaft part and the first connecting part of the rotating shaft assembly and the gap between the main shaft part and the second connecting part of the rotating shaft assembly in the thickness direction of the electronic device, thereby preventing the outer edge of the first support member from interfering with the rotating shaft assembly due to being located in the gap of the rotating shaft assembly, thereby affecting the opening and closing of the electronic device. At the same time, the first support member can overlap the first connecting part and the second connecting part, which is conducive to providing a relatively flat support environment for the fixed assembly of subsequent components.

[0012] In one possible implementation, the main shaft portion has a flat surface. The flat surface is positioned toward the screen, and the second portion of the first support member is fixedly connected to the flat surface. When the electronic device is in the open position, the flat surface is parallel to the screen. Thus, the main shaft portion of the hinge assembly has a relatively flat surface, facilitating securement between the elastic component and the main shaft portion.

[0013] In one possible implementation, the thickness of the first support member is less than or equal to the thickness of the first elastic member. In this way, the first support member is thinner, which helps reduce the rebound force when the electronic device is bent, thereby improving the opening and closing experience of the electronic device.

[0014] In one possible implementation, the first elastic member is provided with at least one first through hole. The first through hole exposes a portion of the first support member. The elastic component also includes at least one first adhesive. The first adhesive is located in the first through hole and connects the first support member and the screen. In this way, the first adhesive can utilize the thickness space of the first elastic member, so that while achieving the fixation of other components, the thickness of the elastic component will not be increased, which is conducive to achieving a thin design of the electronic device. At the same time, the through hole on the first elastic member (that is, the first through hole in this embodiment) can also be used to control the thickness of the first adhesive, thereby avoiding the problem that the first adhesive is too thin to ensure the connection stability of other components, and avoiding the problem that the first adhesive is too thick and causes the screen to be uneven.

[0015] In one possible implementation, the first support member is provided with at least one second through hole. The second through hole exposes a portion of the main shaft portion. The second through hole is connected to the first through hole. The opening size of the second through hole is no larger than the opening size of the first through hole. When the electronic device is in the open state, the first through hole and the second through hole at least partially overlap in the thickness direction of the electronic device. A first adhesive is located in the second through hole and the first through hole, connecting a portion of the main shaft portion, a portion of the first support member, and a portion of the screen.

[0016] It is understood that in this embodiment, the opening of the second through-hole of the first support member may be no larger than the opening of the first through-hole of the first elastic member. When the opening of the second through-hole is equal to the opening of the first through-hole, the second through-hole can also expose the portion of the main shaft exposed by the first through-hole, allowing the first adhesive to securely connect other components to the shaft assembly. When the opening of the second through-hole is smaller than the opening of the first through-hole, the first through-hole can also expose a portion of the upper surface of the first support member. In this way, when the second support member is fixed by the first adhesive, on the one hand, the opening of the second through hole is smaller, and the second through hole only exposes part of the flat surface a of the hinge assembly, so that the first adhesive can realize the fixed connection between the second support member and the hinge assembly while the first adhesive will not overflow from the second through hole to other components of the hinge assembly, thereby effectively avoiding the problem of other components adhering to each other due to the overflow of the first adhesive; on the other hand, the opening of the first through hole is larger than the opening of the second through hole, so that the second support member can be directly fixedly connected to the hinge assembly by the first adhesive while also being fixedly connected to the upper surface of the first support member by the first adhesive, so as to increase the fixing area of ​​the first adhesive and the first support member, thereby effectively improving the connection stability between the second support member and the hinge assembly while also improving the connection stability between the second support member and the first support, which is beneficial to improving the overall structural stability of the electronic device.

[0017] In one possible implementation, the support portion further includes a second support member. When the electronic device is in the open position, the second support member is stacked between the first elastic member and the screen in the thickness direction of the electronic device. This allows the elastic assembly to have a larger number of support members, allowing the entire support portion to better absorb the impact and / or squeezing force of the hinge assembly on the screen, reducing the impact force on the screen and providing good rigid support for the screen, thereby improving the reliability of the screen in the event of a drop and extending the service life of the electronic device.

[0018] In one possible implementation, when the electronic device is in the open state, the width of the gap between the first connecting portion and the second connecting portion in the first direction is greater than or equal to the width of the second support member in the first direction. This allows the second support member to be narrower, effectively reducing the rebound force when the second support member is bent, making the opening and closing of the electronic device smoother and improving the user experience.

[0019] In one possible implementation, the elastic component also includes a second adhesive. The second adhesive connects the second support member and the screen. When the electronic device is in the open state, the second adhesive is stacked between the second support member and the screen in the thickness direction of the electronic device. When the electronic device is in the open state, the direction in which the first shell points to the second shell is the first direction, and in the first direction, the width of the second adhesive is less than or equal to the width of the second support member. In this way, most of the second adhesive can be located directly above the main shaft portion of the hinge assembly, and the width of the second adhesive is narrow, which can effectively reduce the rebound force when the second adhesive is bent, which is conducive to improving the opening and closing experience of the electronic device.

[0020] In one possible implementation, the elastic portion further includes a second elastic member. The second elastic member is fixed between the second support member and the screen. The first support member, the first elastic member, the second support member, and the second elastic member are arranged in sequence along a direction of the rotating shaft assembly pointing toward the screen.

[0021] It will be appreciated that the elastic assembly in this embodiment may include a first support member, a first elastic member, a second support member, and a second elastic member. The first support member, the first elastic member, the second support member, and the second elastic member may be arranged sequentially along the direction of the rotating shaft assembly toward the screen and arranged in a stacked manner. The first support member and the second support member may together constitute the support portion of the elastic assembly. The first elastic member and the second elastic member may together constitute the elastic portion of the elastic assembly. Thus, by alternating and stacking the multiple support members (in this embodiment, the first support member and the second support member) and the multiple elastic members (in this embodiment, the first elastic member and the second elastic member) in the elastic assembly, the entire elastic assembly can form a structure similar to a bulletproof vest, which helps improve the elastic assembly's impact and compression resistance. Compared to simply increasing the thickness of the first support member and the first elastic member to improve the elastic assembly's impact and compression resistance, the elastic assembly in this embodiment, under conditions of equal thickness, has better impact and compression resistance. Under the same performance conditions, the thickness of each support member and each elastic member of the elastic component in this embodiment is relatively thin, and the multiple support members and the multiple elastic members are fixed to each other by an adhesive layer. In this way, when the electronic device is bent, a certain degree of displacement can occur between the adjacent support members and elastic members, thereby greatly reducing the rebound force of the entire elastic component when it is bent. In other words, under certain performance conditions, the thickness of the elastic component in this embodiment can be thinner, which is conducive to the realization of a thin design of the electronic device. At the same time, the total thickness of the elastic part of the elastic component in this embodiment can be in the range of .mm to .mm, and the total thickness of the support part can be less than or equal to the total thickness of the elastic part. In this way, the elastic component can have good impact resistance and extrusion resistance while having a thin total thickness, which is conducive to the realization of a thin design of the electronic device.

[0022] Secondly, compared with the case where the support member is arranged adjacent to the screen, the support member has a larger rebound force when bent, which can easily damage the screen when bent. In this embodiment, an elastic member (also known as the second elastic member in this embodiment) can be arranged adjacent to the screen. The elastic member has a smaller rebound force when bent, which can effectively reduce the chance of damage to the screen when bent, and is beneficial to extending the service life of the electronic device.

[0023] In one possible implementation, the support portion includes a first support member and a second support member. The elastic portion includes a first elastic member and a second elastic member. The first elastic member, the first support member, the second elastic member, and the second support member are arranged in sequence along a direction of the hinge assembly pointing toward the screen.

[0024] It is understandable that the elastic component in this embodiment can include a first support member, a first elastic member, a second support member, and a second elastic member at the same time, and the first elastic member, the first support member, the second elastic member, and the second support member can be arranged in sequence along the direction of the rotating shaft assembly toward the screen and arranged in a stacked manner. In this way, compared to the elastic member being arranged adjacent to the screen, the elastic member has limited ability to disperse and / or absorb impact force when the electronic device falls, which can easily cause the screen to be damaged when it falls. In this embodiment, the support member (also known as the second support member in this embodiment) can be arranged adjacent to the screen. When the electronic device falls, the support member can better absorb the impact force and provide good rigid support for the screen, thereby effectively reducing the chance of damage to the screen when it falls, which is beneficial to extending the service life of the electronic device.

[0025] In one possible implementation, the elastic component further includes a third adhesive bond. The third adhesive bond is connected between the second elastic member and the screen. When the electronic device is in the open state, the width of the third adhesive bond in the first direction is equal to the width of the second elastic member. This allows the third adhesive bond to secure the second elastic member to the screen while minimizing the impact of rebound force when the electronic device is bent, thereby improving the opening and closing experience of the electronic device.

[0026] In one possible implementation, the screen includes a first part, a second part, and a third part, which are arranged in sequence along a first direction. The first part is connected to the first shell. The third part is connected to the second shell. The second part is connected between the first part and the third part. When the electronic device is in an open state, the screen is flattened, and the first part, the second part, and the third part are arranged in sequence along the first direction. In the thickness direction of the electronic device, the second part and the hinge assembly are stacked. The width of the second elastic member in the first direction is greater than or equal to the width of the second part in the first direction. When the electronic device is in a closed state, the first part and the third part are folded relative to each other, and the second part is bent. In this way, the second elastic member and the third adhesive can enhance the rigidity of the screen, thereby effectively preventing the electronic device from falling when in an open state, causing a part of the screen to arch, which is beneficial to improving the overall structural strength of the screen and extending the service life of the screen.

[0027] In one possible implementation, the elastic assembly further includes a lubricating member. The lubricating member is fixedly connected to the surface of the first elastic member facing away from the first support member. The provision of the lubricating member effectively reduces the coefficient of friction between the first elastic member and other components located above it, thereby improving the opening and closing experience of the electronic device.

[0028] In one possible implementation, the lubricating component includes a main body, a first bent portion, and a second bent portion. The main body connects the first bent portion and the second bent portion. The first bent portion includes a first connecting portion and a first extending portion. The second bent portion includes a second connecting portion and a second extending portion. When the electronic device is in the open position, the first extending portion is spaced apart from the main body along the thickness direction of the electronic device. The second extending portion is spaced apart from the main body along the thickness direction of the electronic device. The first extending portion and the second extending portion are located on the side of the main body facing the hinge assembly. The first extending portion and the second extending portion are spaced apart. The first connecting portion connects the main body and the first extending portion. The second connecting portion connects the main body and the second extending portion. The main body, the first connecting portion, and the first extending portion form a first semi-enclosed accommodating space. The main body, the second connecting portion, and the second extending portion form a second semi-enclosed accommodating space. Part of the first elastic member and at least part of the first portion of the first support member are located in the first semi-enclosed accommodating space. Part of the first elastic member and at least part of the third portion of the first support member are located in the second semi-enclosed accommodating space.

[0029] It is understood that, compared to providing two lubricating members, one on the surface of the first support member facing away from the first elastic member and the other on the surface of the first elastic member facing away from the first support member, where the outer edge of the first support member is exposed to the external environment, the lubricating member in this embodiment can have a main portion covering the surface of the first elastic member facing away from the first support member, and also have a first bent portion that bends toward the first portion of the first support member and a second bent portion that bends toward the third portion of the first support member. In this way, the lubricating member not only simultaneously covers the surface of the first elastic member, a portion of the surface of the first portion of the first support member, and a portion of the surface of the third portion of the first support member, but also wraps around the outer edges of the first elastic member and the first support member, thereby protecting the outer edges of the first elastic member and the first support member from scratching against other components and generating abnormal noise. Furthermore, the first support member is relatively thin, and its outer edge is relatively sharp. By arranging a lubricating part to wrap the outer edge of the first support part (in this embodiment, that is, the edge of the first part of the first support part away from the third part and the edge of the third part away from the first part), it can also effectively prevent the edge of the first support part from scratching the assembler during the installation of the first support part with other components, which is beneficial to improving the safety of the assembly process.

[0030] In one possible implementation, when the electronic device is in an open state, the main body, the first elastic member, the first portion of the first support member, and the first extension are stacked in sequence in the thickness direction of the electronic device. The first connecting portion is arranged on the side of the first portion of the first support member away from the third portion of the first support member. The main body, the first elastic member, the third portion of the first support member, and the second extension are stacked in sequence. The second connecting portion is arranged on the side of the third portion of the first support member away from the first portion of the first support member. In this way, the lubricating member can better wrap the outer edge of the first support member, thereby effectively preventing the outer edge of the first support member from scratching against other components and generating abnormal noise.

[0031] In one possible implementation, the first elastic member extends in a direction that includes a first end and a second end that are oppositely disposed. The first end is provided with at least one groove. The groove opens in a direction that is the second end pointing toward the first end.

[0032] It can be understood that in this embodiment, by providing one or more grooves at the first end and the second end of the first elastic member, a release space can be provided for the first elastic member to bulge at its ends (i.e., the first end and the second end) when the electronic device falls in the open state. This can effectively avoid the problem that the first elastic member bulges at the edges of its ends when the electronic device falls in the open state, causing the screen to bulge, resulting in the breakage of the screen wiring and the failure of the screen. This is beneficial to extending the service life of the screen and improving user experience.

[0033] In one possible implementation, a first portion of the first support member is provided with a plurality of first holes. The plurality of first holes are spaced apart along a longitudinal extension direction of the first support member. A third portion of the first support member is provided with a plurality of second holes, the plurality of second holes being spaced apart along a longitudinal extension direction of the first support member. The longitudinal extension directions of the first holes and the longitudinal extension directions of the second holes both intersect the longitudinal extension direction of the first support member.

[0034] It can be understood that in this embodiment, by providing a plurality of first holes whose extension directions intersect with the length extension direction of the first support member on the first part of the first support member, and providing a plurality of second holes whose extension directions intersect with the length extension direction of the first support member on the third part of the first support member, the rebound force when the first support member is bent can be effectively reduced, which is conducive to improving the opening and closing experience of the electronic device.

[0035] In a possible implementation, the first support member is in the shape of an elongated strip, and at least one corner of the first support member has an escape space.

[0036] It can be understood that in this embodiment, the corners of the first support member are trimmed to form an avoidance space c, so that the edge of the first support member can be away from the antenna inside the electronic device, thereby reducing the radio frequency interference of the first support member on the antenna inside the electronic device and reducing the impact of the first support member on the antenna performance of the entire device.

[0037] In one possible implementation, the thickness of the support portion is less than or equal to the thickness of the elastic portion. Thus, the total thickness of the support portion can be less than or equal to the total thickness of the elastic portion. This allows the elastic component to have excellent impact and compression resistance while remaining relatively thin, facilitating the thinning of electronic devices.

[0038] In one possible implementation, the hinge assembly is located inside the screen. This allows the electronic device to be an inward-folding screen device. When the electronic device is dropped, particularly when the device is closed, the support portion of the elastic assembly can effectively absorb the impact and / or compressive force exerted by the hinge assembly on the screen, reducing the impact force on the screen and providing good rigid support for the screen. The elastic portion of the elastic assembly can effectively elastically resist the impact and / or compressive force exerted on the screen, while also absorbing and dissipating the impact and / or compressive force on the screen. The elastic assembly effectively absorbs the impact force exerted on the screen by the drop, preventing the screen from experiencing bright spots and dark spots due to strong collisions with the hinge assembly, thereby improving the structural reliability of the screen and extending its service life. In other words, the screen in this embodiment does not sacrifice its thickness. The elastic assembly located between the screen and the hinge assembly effectively improves the reliability of the screen when dropped. Furthermore, the overall thinness of the screen effectively reduces the rebound force when the electronic device is bent, improving the user's opening and closing experience.

[0039] In one possible implementation, the first shell includes a first mounting slot. The second shell includes a second mounting slot. When the electronic device is in an open state, the first mounting slot and the second mounting slot form a receiving space. At least part of the hinge assembly and at least part of the elastic assembly are located in the receiving space. In this way, at least part of the elastic assembly can be located in the receiving space. On the one hand, the elastic assembly can utilize the thickness space of the shell device, so that the elastic assembly can ensure the drop reliability of the screen while not increasing the thickness of the entire electronic device, which is conducive to realizing a thin design of the electronic device; on the other hand, there is no height difference between the elastic assembly and the first adhesive backing and the second adhesive backing of the shell device, thereby providing a relatively flat support environment for the screen, improving the display effect of the screen, and enhancing the user experience.

[0040] In a second aspect, a screen assembly is provided. The screen assembly includes a screen and at least one elastic member. The screen includes a first portion, a second portion, and a third portion, with the second portion connected between the first portion and the third portion. The elastic member is located on the non-display side of the screen, and a portion of the elastic member is fixedly connected to the second portion. The elastic member is made of an elastic material or a non-Newtonian fluid material. The width of the elastic member in a first direction is less than the width of the screen in the first direction. The first direction is the direction in which the first portion points to the second portion when the screen assembly is in the open state.

[0041] It is understood that, compared to sequentially stacking the elastic member and the screen and affixing them to the hinge assembly of the electronic device, in this embodiment, the elastic member and the screen are first assembled together to form a screen assembly, and then the entire screen assembly is affixed to the hinge assembly. This provides a relatively flat supporting environment for the elastic member during assembly, making it easier to assemble the elastic member on the screen. It also helps reduce bubbles in the adhesive between the elastic member and the screen, thereby effectively improving the stability of the connection between the elastic member and the screen. It also effectively avoids debonding and delamination between the elastic member and the screen at the bubbles caused by repeated opening and closing of the electronic device, thereby improving the overall structural stability of the electronic device and extending its service life.

[0042] In one possible implementation, the width of the elastic member in the first direction is greater than or equal to the width of the bent portion in the first direction. This allows the elastic member to enhance the rigidity of the screen, effectively preventing the screen from arching due to a drop of the electronic device when opened. This improves the overall structural strength of the screen and extends its lifespan.

[0043] In one possible implementation, the screen assembly further includes at least one support member. The support member is fixedly connected to the surface of the elastic member facing away from the screen, and the material of the support member is a rigid material. The width of the support member in the first direction is less than or equal to the width of the elastic member in the first direction. In this way, the screen can provide a relatively flat support environment during the assembly process of the support member, making it easier to assemble the support member on the screen. It is also beneficial to reduce bubbles in the adhesive between the support member and the elastic member, thereby effectively improving the connection stability between the support member and the elastic member, and effectively avoiding the problem of debonding and stratification of the support member and the elastic member at the bubbles due to repeated opening and closing of the electronic device, which is beneficial to improving the overall structural stability of the electronic device and extending the service life of the electronic device.

[0044] In one possible implementation, the thickness of the support member is less than or equal to the thickness of the elastic member. This thinner support member effectively reduces the rebound force when the support member is bent, making the opening and closing of the electronic device smoother and improving the user experience.

[0076] The embodiments of the present application are described below in conjunction with the accompanying drawings in the embodiments of the present application.

[0077] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified 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 remains unchanged after the connection. "Rotational connection" means that the two are connected to each other and can rotate relative to each other after the connection. "Sliding connection" means that the two are connected to each other and can slide relative to each other after the connection. The directional terms mentioned in the embodiments of the present application, such as "up", "down", "left", "right", "inside", "outside", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments 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 embodiments of the present application. "Multiple" means at least two.

[0078] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first," "second," "third," or "fourth" may explicitly or implicitly include one or more of the features.

[0079] In the embodiments of this application, "and / or" is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0080] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof all mean "including but not limited to," unless otherwise specifically emphasized.

[0081] It is understood that the specific embodiments 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.

[0082] Fig. 1 is a schematic diagram of the structure of an electronic device 1000 provided in an embodiment of the present application when in an open state. Fig. 2 is a schematic diagram of the structure of the electronic device 1000 shown in Fig. 1 when in a closed state.

[0083] As shown in Figures 1 and 2, electronic device 1000 may include a housing device 200 and a screen 300. The screen 300 may be mounted on the housing device 200. The housing device 200 may be in an open state, as shown in Figure 1, or a closed state, as shown in Figure 2. The housing device 200 may also be in an intermediate state between unfolded and folded. The intermediate state may be any state between the open and closed states. The screen 300 may move with the housing device 200. The housing device 200 may cause the screen 300 to unfold or fold, allowing the electronic device 1000 to unfold to an open state or fold to a closed state. When the electronic device 1000 is in the closed state, the housing device 200 may be located inside the screen 300. In other words, the electronic device 1000 may be an outward-folding screen electronic device 1000. For ease of understanding, the direction in the same direction as the light emission direction of the screen 300 is defined as "upward," and the direction opposite to the light emission direction of the screen 300 is defined as "downward." In some embodiments, the electronic device 1000 may also be an inward-folding screen electronic device.

[0084] In this embodiment, when the electronic device 1000 is in the open state, the screen 300 can be flattened. In this case, the screen 300 can display a full-screen image, and the electronic device 1000 has a larger display area, which is conducive to improving the user's viewing and operating experience. When the electronic device 1000 is in the closed state, the planar size of the electronic device 1000 is small, making it easier for the user to carry and store.

[0085] Exemplarily, the screen 300 may be integrated with a display function and a touch sensing function. The display function of the screen 300 is used to display images, videos, etc., and the touch sensing function of the screen 300 is used to sense the user's touch actions to achieve human-computer interaction. Exemplarily, the screen 300 includes a flexible display screen that can be bent. Among them, the flexible display screen can adopt 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.

[0086] For example, the electronic device 1000 may further include multiple components (not shown in the figure), which are installed inside the housing device 200. 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, a headphone jack, a sensor module, a button, a motor, an indicator, and a subscriber identification module (SIM) card interface.

[0087] It should be understood that Figures 1 and 2 only schematically illustrate some components of the electronic device 1000, and the actual shape, size, and structure of these components are not limited by Figures 1 and 2. In other embodiments, when the electronic device 1000 is a device of other forms, the electronic device 1000 may also not include the screen 300.

[0088] 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 parts and a bent part connected between the two flat parts. Among them, the two flat 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 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 that folds three or more, that is, the electronic device 1000 includes three or more flat parts, and two adjacent flat parts are connected by a bent part, and the two adjacent flat parts can be rotated relative to each other to overlap each other or rotated away from each other to be flattened. When the electronic device 1000 is a structure that folds three or more, the structure of the electronic device 1000 can be adaptively designed with reference to the description of the two-fold structure in this embodiment, and this application will not go into details about this.

[0089] FIG3 is a schematic diagram of a partially exploded structure of the electronic device 1000 shown in FIG1 in some embodiments. FIG4 is a schematic diagram of a partial cross-section structure of the electronic device 1000 shown in FIG1 taken along line AA in one embodiment. FIG5 is a schematic diagram of a partial cross-section structure of the electronic device 1000 shown in FIG2 taken along line BB in one embodiment.

[0090] As shown in Figures 3 to 5, the housing device 200 may include a hinge assembly 210, a first housing 220, and a second housing 230. The hinge assembly 210 can connect the first housing 220 and the second housing 230. The hinge assembly 210 can move, allowing the first housing 220 and the second housing 230 to unfold relative to each other to an open state, or fold relative to each other to a closed state. It should be understood that the first housing 220 and the second housing 230 are both housing members used to mount and secure other components of the electronic device 1000 and can have a variety of structures. The hinge assembly 210 is used to facilitate relative movement between the first housing 220 and the second housing 230 and can also have a variety of structures. The embodiments of this application do not strictly limit the specific structures of the first housing 220, the second housing 230, and the hinge assembly 210. The figures of this application only illustrate the general structure of the first housing 220, the second housing 230, and the hinge assembly 210 in one embodiment.

[0091] Illustratively, the shaft assembly 210 may include a first connecting portion 211, a second connecting portion 212, and a main shaft portion 213. The first connecting portion 211 and the second connecting portion 212 may have a generally symmetrical structure. The first connecting portion 211 and the second connecting portion 212 may both be connected to the main shaft portion 213. The first connecting portion 211 and the second connecting portion 212 may both move relative to the main shaft portion 213 to achieve relative expansion and folding.

[0092] Exemplarily, the upper surface of the main shaft portion 213 can be roughly an arc-shaped surface. Part of the upper surface of the main shaft portion 213 located at the top of the arc can be a plane, constituting the flat surface 213a of the main shaft portion 213. That is, the flat surface 213a can be arranged close to the screen 300. In this case, the upper surface of the main shaft portion 213 can be an incomplete arc-shaped surface. The flat surface 213a can coincide with the central axis of the main shaft portion 213 in the thickness direction of the rotating shaft assembly 210, that is, the flat surface 213a can be located in the middle position of the main shaft portion 213. In some embodiments, the first connecting portion 211 and the second connecting portion 212 can both include a connecting member for achieving movement and a support plate for achieving support. The support plate can be located above the connecting member.

[0093] For example, the first shell 220 may be provided with a first mounting groove 221. The second shell 230 may be provided with a second mounting groove 231. The first connecting portion 211 of the rotating shaft assembly 210 may be located in the first mounting groove 221 and connected to the first shell 220. The second connecting portion 212 of the rotating shaft assembly 210 may also be located in the second mounting groove 231 and connected to the second shell 230. In this embodiment, the first connecting portion 211 may be fixedly connected to the first shell 220. The second connecting portion 212 may be fixedly connected to the second shell 230. In some embodiments, the first connecting portion 211 may also be movably connected (e.g., rotationally connected and / or slidably connected) to the first shell 220. Alternatively, the first connecting portion 211 may also be indirectly fixedly connected to the first shell 220 through other components.

[0094] For example, the housing device 200 may further include a first adhesive 240 and a second adhesive 250. The first adhesive 240 may be fixedly connected to the upper surface of the first housing 220. The second adhesive 250 may be fixedly connected to the upper surface of the second housing 230. Both the first adhesive 240 and the second adhesive 250 may be used to fix the screen 300.

[0095] When the electronic device 1000 is in the open state, the first housing 220 and the second housing 230 can be relatively flat. The first connecting portion 211 and the second connecting portion 212 of the hinge assembly 210 can be relatively flat. The flat surface 213a of the hinge assembly 210 can be parallel to the screen 300. In this case, the first mounting groove 221 can communicate with the second mounting groove 231. The first mounting groove 221 and the second mounting groove 231 can together form the receiving space 200a of the housing device 200. At least a portion of the hinge assembly 210 can be located within the receiving space 200a. In this case, the height difference between the upper surface of the first adhesive 240 and the bottom wall of the first mounting groove 221 facing the screen 300 in the thickness direction of the electronic device 1000 can be a first distance H1. The width of the hinge assembly 210 is a first width L1. The distance between the first connecting portion 211 and the second connecting portion 212 of the hinge assembly 210 is a second width L2. Part of the main shaft portion 213 can be located within the first mounting groove 221. Another portion of the main shaft portion 213 may be located within the second mounting groove 231. The first connecting portion 211 and the second connecting portion 212 may be located on either side of the main shaft portion 213 and relatively flat. In some embodiments, the first connecting portion 211 may further include a first support plate for providing support and a first connector for connecting to the first housing 220. The first support plate may be fixed to the surface of the first connector facing the screen 300. The second connecting portion 212 may further include a second support plate for providing support and a second connector for connecting to the second housing 230. The second support plate may be fixed to the surface of the second connector facing the screen 300. When the distance between the first and second support plates is less than or equal to the distance between the first and second connectors, the second width L2 is the distance between the first support plate of the first connecting portion 211 and the second support plate of the second connecting portion 212. When the distance between the first and second support plates is greater than the distance between the first and second connectors, the second width L2 is the distance between the first connector of the first connecting portion 211 and the second connector of the second connecting portion 212.

[0096] When the electronic device 1000 is in a closed state, the first housing 220 and the second housing 230 can be folded relative to each other. The first connecting portion 211 and the second connecting portion 212 of the hinge assembly 210 can be folded relative to each other and located on the same side of the main shaft portion 213. The main shaft portion 213 can be exposed relative to the first housing 220 and the second housing 230. For example, the lower surface of the first housing 220 can be in contact with the lower surface of the second housing 230. In other embodiments, when the electronic device 1000 is in a closed state, a gap can exist between the lower surface of the first housing 220 and the lower surface of the second housing 230.

[0097] It should be noted that the width of the hinge assembly 210 refers to the width of the hinge assembly 210 in the first direction when the electronic device 1000 is in the open state. The first direction is the direction in which the first shell 220 points to the second shell 230 when the electronic device 1000 is in the open state. The first direction is perpendicular to the length extension direction of the hinge assembly 210 and the thickness direction of the electronic device 1000 (the first direction is also indicated by an arrow in Figure 4). Unless otherwise specified in the following text of this application, the width direction of a certain component is the first direction shown in Figure 4. The width of a certain component or the distance between two components refers to the width or distance of the component in the first direction when the electronic device 1000 is in the open state.

[0098] Referring again to Figure 3 , electronic device 1000 may further include an elastic assembly 100. The elastic assembly 100 may be fixed between the screen 300 and the hinge assembly 210. When electronic device 1000 is in the open state, the screen 300, the elastic assembly 100, and the hinge assembly 210 may be stacked in sequence. The elastic assembly 100 can be used to improve the reliability of the screen 300 if the electronic device 1000 is dropped. The elastic assembly 100 may include an elastic portion and a supporting portion. The elastic portion and the supporting portion may be stacked along the thickness of the electronic device 1000. The elastic portion may be made of a different material than the supporting portion. The elastic portion may include at least one elastic member. The supporting portion may include at least one supporting member. When the elastic portion includes only one elastic member and the supporting portion also includes only one supporting member, the elastic member and the supporting member may be stacked along the thickness of the electronic device 1000. When the elastic portion includes multiple elastic members and the supporting portion includes multiple supporting members, the multiple elastic members and the multiple supporting members may be stacked alternately.

[0099] When the electronic device 1000 falls and the screen 300 is impacted, the supporting portion of the elastic assembly 100 can effectively absorb the impact and / or compressive force exerted by the hinge assembly 210 on the screen 300, reducing the impact force on the screen 300 and providing good rigid support for the screen 300. The elastic portion of the elastic assembly 100 can effectively elastically absorb the impact and / or compressive force exerted on the screen 300, while also absorbing and dissipating the impact and / or compressive force on the screen 300. In other words, the elastic assembly 100 in this embodiment includes both an elastic portion and a supporting portion, each of which can provide good rigid and elastic protection for the screen 300, respectively. The entire elastic assembly 100 has strong impact and compressive resistance, enabling it to effectively protect the screen 300, improving the drop reliability of the screen 300 and extending the service life of the screen 300.

[0100] In this embodiment, the elastic component 100 may include a first support member 10, a first elastic member 20, a lubricating member 30, a first adhesive 40, a second support member 50, a second adhesive 60, a second elastic member 70, and a third adhesive 80. That is, the supporting portion of the elastic component 100 may include two support members. The elastic portion of the elastic component 100 may include two elastic members. When the electronic device 1000 is in the open state, the first support member 10, the first elastic member 20, the lubricating member 30, the second support member 50, the second adhesive 60, the second elastic member 70, and the third adhesive 80 may be stacked and arranged in sequence along the hinge assembly 210 toward the screen 300.

[0101] When the electronic device 1000 is in an open state, each component of the elastic component 100 can be in an open state accordingly. The width of the elastic component 100 can be less than or equal to the first width L1 (as shown in Figure 4). When the electronic device 1000 is in a closed state, each component of the elastic component 100 can be in a closed state accordingly. In some other embodiments, the elastic component 100 may also not include the second elastic member 70, the second support member 50, the second adhesive 60, the lubricating member 30, and the third adhesive 80.

[0102] The structures and relative positional relationships of the various components in the elastic assembly 100 will be described in detail below with reference to the relevant drawings.

[0103] FIG6 is a schematic structural diagram of the first support member 10 of the elastic assembly 100 shown in FIG3 .

[0104] As shown in FIG6 , the first support member 10 can be made of a rigid material having a certain strength and hardness. The first support member 10 can be in the form of a thin sheet. For example, the first support member 10 can be a steel sheet. The first support member 10 can be bent under the action of an external force. Of course, if the support performance requirements are met, the first support member 10 can also be a metal sheet or non-metal sheet such as an aluminum sheet, a stainless steel sheet, a titanium alloy sheet, an aluminum alloy sheet, a copper alloy sheet, etc., and this application does not impose strict restrictions on this.

[0105] Exemplarily, the first support member 10 may be roughly rectangular. The first support member 10 may include a first portion 11, a second portion 12 and a third portion 13. The second portion 12 may be connected between the first portion 11 and the third portion 13. At this time, the first portion 11, the second portion 12 and the third portion 13 may be arranged in sequence along the width direction of the first support member 10. It should be understood that the first portion 11, the second portion 12 and the third portion 13 of the first support member 10 are schematically divided by dotted lines in Figures 6 and 7. Although the first support member 10 is described as three parts in this embodiment, it does not affect the fact that the first support member 10 can be an integrally formed structure, that is, the first portion 11, the second portion 12 and the third portion 13 of the first support member 10 can be integrally formed.

[0106] FIG. 7 is a schematic diagram of the assembly structure of the first support member 10 and the first elastic member 20 of the elastic assembly 100 shown in FIG. 3 .

[0107] As shown in Figure 7, the material of the first elastic member 20 can be an elastic material or a non-Newtonian fluid material. Among them, the elastic material can be a material with a certain elasticity such as thermoplastic polyurethane elastomer (TPU). The elastic modulus of the elastic material can be much smaller than the elastic modulus of the rigid material. For example, the elastic modulus of thermoplastic polyurethane elastomer can be between 0.01GPa and 1GPa. The elastic modulus of stainless steel can be around 200GPa. Among them, the non-Newtonian fluid material refers to a material with a nonlinear relationship between shear stress and shear strain rate. The hardness of the elastic material can be much greater than the hardness of the non-Newtonian fluid.

[0108] For example, the thickness of the first elastic member 20 can be greater than or equal to the thickness of the first support member 10. The thickness of the first elastic member 20 can be in the range of 0.02 mm to 0.15 mm. For example, the thickness of the first elastic member 20 can be 0.03 mm, 0.042 mm, 0.075 mm, 0.1 mm, or 0.12 mm. Thus, the thinner thickness of the first support member 10 helps reduce the rebound force when the electronic device 1000 is bent.

[0109] For example, the first elastic member 20 may be located above the first support member 10. In this case, the first support member 10 and the first elastic member 20 may be stacked in the second direction. The second direction is the thickness direction of the electronic device 1000 when the electronic device 1000 is in the open state. It should be understood that the second direction referred to below may be subject to the above definition.

[0110] For example, the shape of the first elastic member 20 can be substantially the same as that of the first support member 10. The width of the first elastic member 20 can be the same as that of the first support member 10. The first elastic member 20 can be fixedly connected to the upper surface of the first support member 10 by bonding or other means. Specifically, when the material of the first elastic member 20 is a thermoplastic polyurethane elastomer, a layer of adhesive can be brushed on the surface of the first elastic member 20, and the first elastic member 20 can be fixedly connected to the first support member 10 by the adhesive. When the material of the first elastic member 20 can be a viscous non-Newtonian fluid material, the first elastic member 20 can be directly bonded and fixed to the upper surface of the first support member 10.

[0111] Figure 8 is a schematic diagram of the exploded structure of the first support member 10, first elastic member 20, and lubricating member 30 of the elastic assembly 100 shown in Figure 3. Figure 9a is a schematic diagram of a partial cross-section of the electronic device 1000 shown in Figure 1 taken along line AA in one embodiment. Figure 9b is a schematic diagram of the structure shown in Figure 9a after it has been flipped upside down.

[0112] As shown in Figures 8 to 9a, the lubricating part 30 can be Mylar, such as insulating Mylar. The surface of the lubricating part 30 is relatively smooth and has a low surface roughness. The lubricating part 30 can include a main body 31, a first bend portion 32, and a second bend portion 33. The main body 31 can connect the first bend portion 32 and the second bend portion 33. It should be understood that although the lubricating part 30 is described as three parts in this embodiment, it does not affect the lubricating part 30 being an integrally formed structure, that is, the main body 31, the first bend portion 32, and the second bend portion 33 of the lubricating part 30 can be integrally formed. It should be noted that in Figures 9a and 9b, the main body 31, the first bend portion 32, and the second bend portion 33 of the lubricating part 30 are schematically divided by dotted lines.

[0113] Illustratively, the main body 31 may include a first surface 31a and a second surface 31b disposed opposite each other. The first surface 31a is the surface of the main body 31 facing the screen 300. The second surface 31b is the surface of the main body 31 facing the hinge assembly 210 (see FIG3 ). The first bent portion 32 may include a first connecting portion 321 and a first extending portion 322. The first extending portion 322 may be located on a side of the second surface 31b of the main body 31 away from the first surface 31a. The first extending portion 322 may be spaced apart from the main body 31 in the second direction. The first extending portion 322 may include a third surface 322a and a fourth surface 322b disposed opposite each other. The third surface 322a is the surface of the first extending portion 322 facing the main body 31. The fourth surface 322b is the surface of the first extending portion 322 facing away from the main body 31, that is, the fourth surface 322b is the surface of the first extending portion 322 facing the hinge assembly 210. The end of the first extension portion 322 away from the first connecting portion 321 is the first end 322c. The first connecting portion 321 can connect the main body portion 31 and the first extension portion 322. In this case, the main body portion 31, the first connecting portion 321, and the first extension portion 322 can collectively enclose a first semi-enclosed accommodating space 32a. In other words, the main body portion 31 and the first bent portion 32 can collectively enclose the first semi-enclosed accommodating space 32a. It should be noted that in Figures 9a and 9b, the first connecting portion 321 and the first extension portion 322 of the first bent portion 32 are schematically demarcated by dotted lines.

[0114] Illustratively, the second bent portion 33 may include a second connecting portion 331 and a second extending portion 332. The second extending portion 332 may be located on a side of the second surface 31b of the main body 31 away from the first surface 31a. The second extending portion 332 may be spaced apart from the main body 31 in the second direction. The second extending portion 332 may include a fifth surface 332a and a sixth surface 332b disposed opposite to each other. The fifth surface 332a is the surface of the second extending portion 332 facing the main body 31. The sixth surface 332b is the surface of the second extending portion 332 facing away from the main body 31, that is, the sixth surface 332b is the surface of the second extending portion 332 facing the shaft assembly 210. The end of the second extending portion 332 away from the second connecting portion 331 is the second end 332c. The second connecting portion 331 may connect the main body 31 and the second extending portion 332. In this case, the main body 31, the second connecting portion 331, and the second extending portion 332 can collectively enclose a second semi-enclosed accommodating space 33a. That is, the main body 31 and the second bent portion 33 can collectively enclose the second semi-enclosed accommodating space 33a. In this case, the second extending portion 332 and the first extending portion 322 can be located on the same side of the main body 31. The second extending portion 332 and the first extending portion 322 can be spaced apart along the width of the lubricating element 30. It should be noted that the second connecting portion 331 and the second extending portion 332 of the second bent portion 33 are schematically demarcated by dashed lines in both Figures 9a and 9b.

[0115] As shown in Figures 8 to 9b, the main body 31 of the lubricating member 30 can be located above the first elastic member 20. The second surface 31b of the main body 31 can be fixedly connected to the upper surface of the first elastic member 20 by bonding or other means. The shape of the main body 31 of the lubricating member 30 can be substantially the same as that of the first elastic member 20. The width of the main body 31 of the lubricating member 30 can be the same as that of the first elastic member 20.

[0116] For example, the first bent portion 32 of the lubricating member 30 can be bent relative to the main body 31 until it contacts the lower surface of the first portion 11 of the first support member 10. The first extension 322 of the first bent portion 32 can be located on the side of the first support member 10 facing away from the first elastic member 20. The third surface 322a of the first extension 322 can be fixedly connected to the lower surface of the first portion 11 of the first support member 10 by bonding or other means. The first end 322c of the first extension 322 can face the second extension 332. The first connection portion 321 can be located on a side of the first portion 11 of the first support member 10 away from the third portion 13. In this case, the main body 31 of the lubricating member 30, the first elastic member 20, the first portion 11 of the first support member 10, and the first extension 322 of the lubricating member 30 can be stacked in sequence along the second direction. In this case, a portion of the first elastic member 20 and at least a portion of the first portion 11 of the first support member 10 can be located within the first semi-enclosed accommodating space 32a.

[0117] For example, the second bent portion 33 of the lubricating member 30 can be bent relative to the main body 31 until it contacts the lower surface of the third portion 13 of the first support member 10. The second extension 332 of the second bent portion 33 can be located on the side of the first support member 10 facing away from the first elastic member 20. The fifth surface 332a of the second extension 332 can be fixedly connected to the lower surface of the third portion 13 of the first support member 10 by bonding or other means. The second end 332c of the second extension 332 can face the first extension 322. The second connection portion 331 can be located on a side of the third portion 13 of the first support member 10 away from the first portion 11. In this case, the main body 31 of the lubricating member 30, the first elastic member 20, the third portion 13 of the first support member 10, and the second extension 332 of the lubricating member 30 can be stacked in sequence along the second direction. In this case, a portion of the first elastic member 20 and at least a portion of the third portion 13 of the first support member 10 can be located within the second semi-enclosed accommodating space 33a.

[0118] It will be appreciated that, compared to providing two lubricating members, one on the surface of the first support member facing away from the first elastic member and the other on the surface of the first elastic member facing away from the first support member, where the outer edge of the first support member is exposed to the external environment, the lubricating member 30 in this embodiment can have a main portion 31 covering the surface of the first elastic member 20 facing away from the first support member 10, as well as a first bent portion 32 bent toward the first portion 11 of the first support member 10 and a second bent portion 33 bent toward the third portion 13 of the first support member 10. In this way, the lubricating member 30 not only simultaneously covers the surface of the first elastic member 20, a portion of the surface of the first portion 11 of the first support member 10, and a portion of the surface of the third portion 13 of the first support member 10, but also wraps around the outer edges of the first elastic member 20 and the first support member 10. This protects the outer edges of the first elastic member 20 and the first support member 10, preventing them from scraping against other components and causing noise. Furthermore, the first support member 10 is relatively thin and has a relatively sharp outer edge. By arranging the lubricating member 30 to wrap the outer edge of the first support member 10 (in this embodiment, that is, the edge of the first part 11 of the first support member 10 away from the third part 13 and the edge of the third part 13 away from the first part 11), it can also effectively prevent the edge of the first support member 10 from scratching the assembler during the installation of the first support member 10 with other components, which is beneficial to improving the safety of the assembly process.

[0119] Figure 10 is a schematic diagram of a portion of the structure of the electronic device 1000 shown in Figure 1. Figure 11a is a schematic diagram of a partial cross-section of the portion of the structure of the electronic device 1000 shown in Figure 1 taken along line AA in one embodiment. Figure 11b is a schematic diagram of a partial cross-section of the portion of the structure of the electronic device 1000 shown in Figure 2 taken along line BB in one embodiment.

[0120] As shown in Figures 10 to 11b, the second portion 12 of the first support member 10 can be fixedly connected to the flat surface 213a of the main shaft portion 213 of the rotating shaft assembly 210 by welding, bonding, or other methods. In this case, the second portion 12 of the first support member 10 can be fixedly connected to the main shaft portion 213 of the rotating shaft assembly 210. The length of the first support member 10 can be slightly shorter than the length of the rotating shaft assembly 210.

[0121] When the electronic device 1000 is in the open state, the width of the first support member 10 is a third width L3. The third width L3 can be less than or equal to the first width L1. The third width L3 can also be greater than the second width L2. At this time, the first portion 11 of the first support member 10 and the first extension 322 of the first bent portion 32 of the lubricating member 30 can overlap the first connecting portion 211 of the hinge assembly 210, and the third portion 13 of the first support member 10 and the second extension 332 of the second bent portion 33 of the lubricating member 30 can overlap the second connecting portion 212 of the hinge assembly 210. When the electronic device 1000 is in the closed state, the first portion 11 of the first support member 10 and the first extension 322 of the first bent portion 32 of the lubricating member 30 can overlap the first connecting portion 211 of the hinge assembly 210, and the third portion 13 of the first support member 10 and the second extension 332 of the second bent portion 33 of the lubricating member 30 can overlap the second connecting portion 212 of the hinge assembly 210. The first end 322c of the first extension portion 322 of the lubricating member 30 can be located within the gap between the main shaft portion 213 and the first connecting portion 211 of the rotating shaft assembly 210. The second end 332c of the second extension portion 332 of the lubricating member 30 can be located within the gap between the main shaft portion 213 and the first connecting portion 211 of the rotating shaft assembly 210. In this way, the width of the first support member 10 (i.e., the third width L3) can be smaller than the width of the rotating shaft assembly 210 (i.e., the first width L1). The narrower width of the first support member 10 helps reduce the rebound force when the first support member 10 is bent, thereby improving the opening and closing experience of the electronic device 1000. At the same time, when the electronic device 1000 is in the open state, the width of the first support member 10 can be greater than the distance between the first connecting portion 211 and the second connecting portion 212 of the hinge assembly 210 (i.e., the second width L2). Therefore, whether the electronic device 1000 in this embodiment is in the open state or the closed state, the first support member 10 can partially cover the gap between the main shaft portion 213 and the first connecting portion 211 of the hinge assembly 210, and partially cover the gap between the main shaft portion 213 and the second connecting portion 212 of the hinge assembly 210 in the thickness direction of the electronic device 1000. This can prevent the outer edge of the first support member 10 from interfering with the hinge assembly 210 due to being located in the gap of the hinge assembly 210, thereby affecting the opening and closing of the electronic device 1000. At the same time, the first support member 10 can overlap the first connecting portion 211 and the second connecting portion 212, which is conducive to providing a relatively flat support environment for the fixed assembly of subsequent components. In some embodiments, when the electronic device 1000 is in a closed state, the first end 322 c of the first extension portion 322 of the lubricating member 30 may also overlap the first connecting portion 211 or the main shaft portion 213 .

[0122] For example, the first portion 11 of the first support member 10 can be overlapped with the first connecting portion 211 of the rotating shaft assembly 210 via the first bent portion 32 of the lubricating member 30 and can move relative to the first connecting portion 211. The third portion 13 of the first support member 10 can be overlapped with the second connecting portion 212 of the rotating shaft assembly 210 via the second bent portion 33 of the lubricating member 30 and can move relative to the second connecting portion 212. In this way, when the electronic device 1000 is bent, the first part 11 of the first support member 10 can move together with the first bending part 32 of the lubricating member 30 relative to the first connecting part 211 of the rotating shaft assembly 210, and the third part 13 of the first support member 10 can move together with the second bending part 33 of the lubricating member 30 relative to the second connecting part 212 of the rotating shaft assembly 210. Since the friction coefficient between the lubricating member 30 and the rotating shaft assembly 210 is smaller than the friction coefficient between the first support member 10 and the rotating shaft assembly 210, it can effectively avoid the first support member 10 from directly contacting the rotating shaft assembly 210 when it moves and causing scratches, which is beneficial to reducing abnormal noise when the electronic device 1000 is bent.

[0123] In this embodiment, the second portion 12 of the first support member 10 can be fixedly connected to the main shaft portion 213 by welding. For example, a welding gun can weld the first support member 10 to the flat surface 213a of the rotating shaft assembly 210 at the surface of the portion of the first support member 10 where one or more glue dispensing holes 20a are exposed. At this time, the welding point 10a between the first support member 10 and the rotating shaft assembly 210 can be located on the flat surface 213a of the main shaft portion 213. The welding point 10a can be exposed relative to the glue dispensing hole 20a. The welding point 10a can be spaced apart from the second through hole 14 of the first support member 10. It should be understood that both Figures 10 and 11a illustrate the position of the welding point 10a through dotted circles.

[0124] It is understood that, compared to the case where the first support member 10 is fixedly connected to the main shaft portion 213 of the hinge assembly 210 by bonding, the first support member 10 may become debonded from the hinge assembly 210 during the opening and closing of the electronic device 1000 or when the electronic device 1000 is in some more extreme environments, resulting in problems such as bulging of the screen 300 and breaking of the wiring of the screen 300. In this embodiment, the first support member 10 is fixedly connected to the main shaft portion 213 of the hinge assembly 210 by welding, so that the first support member 10 can be more stably fixed to the hinge assembly 210. In this way, even if the electronic device 1000 is opened and closed multiple times or the electronic device 1000 is in some more extreme environments, the first support member 10 can maintain a fixed connection with the hinge assembly 210, thereby effectively avoiding the problems of bulging of the screen 300 and breaking of the wiring due to the detachment of the first support member 10, which is beneficial to improving the overall structural stability of the electronic device 1000 and extending the service life of the electronic device 1000.

[0125] Secondly, compared to stacking and fixing the first support member 10, the first elastic member 20 and the lubricating member 30 in sequence on the rotating shaft assembly 210, in this embodiment, the first support member 10, the first elastic member 20 and the lubricating member 30 are first assembled together to form a whole, and then the whole is fixed together on the rotating shaft assembly 210. In this way, on the one hand, it can effectively prevent the adhesive from overflowing onto the housing device 200 of the electronic device 1000 during the fixing process of the first elastic member 20 and the fixing process of the lubricating member 30, causing some components to stick to each other, thereby affecting the opening and closing experience of the electronic device 1000; on the other hand, the first support member 10 and the first elastic member 20 are both flat sheet structures, so that the first elastic member 20 and the lubricating member 30 can be assembled in a relatively flat support environment during the bonding and fixing process, and the first support member 10, the first elastic member 20 and the lubricating member 30 are easier to assemble. At the same time, it is also beneficial to reduce the bubbles in the adhesive between the first support member 10, the first elastic member 20 and the lubricating member 30, thereby improving the connection stability between the first support member 10, the first elastic member 20 and the lubricating member 30, and effectively preventing the first elastic member 20 or the lubricating member 30 from debonding and stratifying at the bubbles due to multiple opening and closing of the electronic device 1000, which is beneficial to improving the overall structural stability of the electronic device 1000 and extending the service life of the electronic device 1000.

[0126] Fig. 12 is a partial structural diagram of the electronic device 1000 shown in Fig. 1. Fig. 13 is a partial cross-sectional structural diagram of a partial structure of the electronic device 1000 shown in Fig. 1 taken along line AA in one embodiment.

[0127] As shown in Figures 12 and 13, the first elastic member 20 may be provided with a plurality of first through holes 21. The plurality of first through holes 21 may be arranged at intervals along the length extension direction of the first elastic member 20. The shapes and sizes of the plurality of first through holes 21 may not be exactly the same. The second portion 12 of the first support member 10 may be provided with a plurality of second through holes 14. The plurality of second through holes 14 may be arranged at intervals along the length extension direction of the first support member 10. The shapes and sizes of the plurality of second through holes 14 may not be exactly the same. The second through holes 14 may partially expose the flat surface 213a of the main shaft portion 213. For example, the number of first through holes 21 may be the same as the number of second through holes 14. The plurality of first through holes 21 may expose the plurality of second through holes 14 in a one-to-one correspondence and connect the plurality of second through holes 14. At this time, the first through holes 21 may also partially expose the flat surface 213a of the main shaft portion 213.

[0128] Exemplarily, the opening size of the second through holes 14 in each group of second through holes 14 and the first through holes 21 may not be larger than the opening size of the first through holes 21. At this time, in the thickness direction of the electronic device 1000, the first through holes 21 and the second through holes 14 may at least partially overlap. In this embodiment, the opening size of the second through holes 14 in each group of second through holes 14 and the first through holes 21 may be smaller than the opening size of the first through hole 21. At this time, the plurality of first through holes 21 may also expose part of the upper surface of the first support member 10 around the plurality of second through holes 14 in a one-to-one correspondence, for example, expose part of the upper surface of the second portion 12 of the first support member 10. In other embodiments, the opening size of the second through holes 14 in each group of second through holes 14 and the first through holes 21 may be equal to the opening size of the first through hole 21. At this time, the plurality of first through holes 21 may only expose part of the flat surface 213a of the main shaft portion 213.

[0129] Exemplarily, the lubricating member 30 may be provided with a plurality of third through holes 34. The plurality of third through holes 34 may be arranged at intervals along the longitudinal extension direction of the lubricating member 30. The shapes and sizes of the plurality of third through holes 34 may not be exactly the same. Exemplarily, the number of third through holes 34 may be the same as the number of first through holes 21. The plurality of third through holes 34 may expose the plurality of first through holes 21 in a one-to-one correspondence and connect the plurality of first through holes 21. At this time, the plurality of third through holes 34 may form a plurality of dispensing holes 20a in a one-to-one correspondence with the plurality of first through holes 21. Among them, the shape and size of the third through holes 34 and the first through holes 21 in each group of first through holes 21 and third through holes 34 may be substantially the same, that is, the opening size of the third through holes 34 in the same group may be the same size as the opening size of the first through holes 21. At this time, the plurality of third through holes 34 may also expose the portion of the upper surface of the first support member 10 exposed by the plurality of second through holes 14 and the plurality of first through holes 21 in a one-to-one correspondence. That is, the plurality of dispensing holes 20a can correspond one to one to expose the portion of the upper surface of the first support member 10 exposed by the plurality of second through holes 14 and the plurality of first through holes 21. It should be noted that the first through holes 21, the second through holes 14 and the third through holes 34 are also schematically shown in Figures 6 to 10.

[0130] As shown in Figures 12 and 13, the first adhesive 40 can be in a block shape. The number of the first adhesive 40 can be multiple. The thickness of the multiple first adhesives 40 can be the same. The number of the first adhesives 40 can be the same as the number of the dispensing holes 20a. The multiple first adhesives 40 can be located in the multiple dispensing holes 20a and the multiple second through holes 14 in a one-to-one correspondence. At this time, each first adhesive 40 can be roughly in the shape of an inverted "convex". A portion of the first adhesive 40 can be located in the second through hole 14 and connect the flat surface 213a of the rotating shaft assembly 210 and the peripheral side wall of the second through hole 14 (that is, the first support member 10). Another portion of the first adhesive 40 can be located in the dispensing hole 20a and connect the portion of the upper surface of the first support member 10 exposed in the dispensing hole 20a. Exemplarily, the first adhesive 40 can be a hot melt adhesive. Hot melt adhesive can be filled in each dispensing hole 20a, and before being solidified, can flow into the plurality of second through holes 14 one by one. After the hot melt adhesive is solidified, a first adhesive 40 in the shape of an inverted "convex" can be formed.

[0131] In some embodiments, the sizes of the various second through holes 14 may not be exactly the same. For example, the length of one or more second through holes 14 located in the middle of the plurality of second through holes 14 may be slightly larger than the lengths of the remaining second through holes 14. The spacing distance between any two adjacent second through holes 14 may not be exactly the same. The length extension direction of the second through holes 14 is the same as the length extension direction of the first support member 10. In this way, by changing the length of each second through hole 14 and changing the spacing between two adjacent second through holes 14, when the subsequent first support member 10 is fixedly connected to the shaft assembly 210, each second through hole 14 can avoid the uneven structure in the main shaft portion 213 of the shaft assembly 210, thereby facilitating the subsequent installation and fixation of other components (please refer to Figure 4).

[0132] In other embodiments, the first elastic member 20 may also be provided with only one first through hole 21, and the lubricating member 30 may also be provided with only one third through hole 34. The first through hole 21 may be an elongated through hole, exposing all the second through holes 14 and a portion of the upper surface of the first support member 10 around each second through hole 14. The third through hole 34 may be the same shape and size as the first through hole 21, and expose the first through hole 21. In this case, the first through hole 21 and the third through hole 34 may together constitute an elongated dispensing hole 20a. The number of the first adhesive 40 may also be one. In this case, the first adhesive 40 may be in the shape of an elongated strip, adapted to the shape of the dispensing hole 20a. The elongated first adhesive 40 may simultaneously fill the elongated dispensing hole 20a and multiple second through holes 14.

[0133] In other embodiments, the number of first through holes 21 and the number of third through holes 34 may not be equal. In this case, the relationship between the plurality of first through holes 21 and the plurality of third through holes 34 may be two to one. For example, one third through hole 34 may expose two first through holes 21. Alternatively, the relationship between the plurality of first through holes 21 and the plurality of third through holes 34 may be three to one, one to two, or two to three. In other words, there are various combinations of the plurality of first through holes 21 and the plurality of third through holes 34. This is not specifically limited in this application.

[0134] Figure 14 is a schematic diagram of a portion of the structure of the electronic device 1000 shown in Figure 1. Figure 15a is a schematic diagram of a partial cross-section of the portion of the structure of the electronic device 1000 shown in Figure 1 taken along line AA in one embodiment. Figure 15b is a schematic diagram of a partial cross-section of the portion of the structure of the electronic device 1000 shown in Figure 2 taken along line BB in one embodiment.

[0135] As shown in Figures 14 to 15b, the second support member 50 can be made of a rigid material with a certain strength and hardness. The second support member 50 can be in the form of a thin sheet. For example, the second support member 50 can be a steel sheet. The second support member 50 can be bent under the action of an external force. Of course, if the support performance requirements are met, the second support member 50 can also be a metal sheet such as an aluminum sheet, a stainless steel sheet, or a non-metallic sheet. This application does not impose strict restrictions on this. The length of the second support member 50 can be slightly shorter than the length of the shaft assembly 210.

[0136] Exemplarily, the second support member 50 can be located above the lubricating member 30. The second support member 50 can be fixedly connected to the first adhesive 40. In this case, the second support member 50 can be fixedly connected to the flat surface 213a of the main shaft portion 213 of the hinge assembly 210 via the first adhesive 40. All portions of the second support member 50, except for those fixedly connected to the first adhesive 40, can overlap the lubricating member 30 and be movable relative to the lubricating member 30. When the electronic device 1000 is in the open state, the width of the second support member 50 is a fourth width L4. The fourth width L4 can be less than or equal to the third width L3. Exemplarily, the fourth width L4 can also be less than or equal to the second width L2. In this case, the second support member 50 and the first connecting portion 211 of the hinge assembly 210 do not overlap in the thickness direction of the electronic device 1000. The second support member 50 and the second connecting portion 212 of the hinge assembly 210 also do not overlap in the thickness direction of the electronic device 1000. When the electronic device 1000 is in the closed state, the second support member 50 and the first connecting portion 211 of the hinge assembly 210 do not overlap in the thickness direction of the electronic device 1000. The second support member 50 and the second connecting portion 212 of the hinge assembly 210 also do not overlap in the thickness direction of the electronic device 1000. This narrow width of the second support member 50 effectively reduces the rebound force when the second support member 50 is bent, making the opening and closing of the electronic device 1000 smoother and improving the user experience.

[0137] It is understood that in this embodiment, by respectively providing the first through hole 21 in the first elastic member 20, the second through hole 14 in the first support member 10, and the third through hole 34 in the lubricating member 30, the first adhesive 40 can be located within the above-mentioned through holes and can contact the flat surface 213a of the rotating shaft assembly 210. In this way, on the one hand, the second support member 50 can be directly fixed to the flat surface 213a of the rotating shaft assembly 210 via the first adhesive 40, which is conducive to improving the connection stability of the second support member 50; on the other hand, the first adhesive 40 can utilize the thickness space of the first support member 10, the first elastic member 20, and the lubricating member 30, thereby achieving the fixation of the second support member 50 without increasing the thickness of the elastic assembly 100, which is conducive to achieving a thin design of the electronic device 1000. At the same time, the through holes on the first support member 10, the first elastic member 20 and the lubricating member 30 (that is, the second through hole 14, the first through hole 21 and the third through hole 34 in this embodiment) can also be used to control the thickness of the first adhesive 40, thereby avoiding the problem that the first adhesive 40 is too thin to ensure the connection stability of the second support member 50, and avoiding the problem that the first adhesive 40 is too thick to cause the screen 300 to be uneven.

[0138] Secondly, in this embodiment, the opening of the second through hole 14 of the first support member 10 may be no larger than the opening of the first through hole 21 of the first elastic member 20. When the opening of the second through hole 14 is equal to the opening of the first through hole 21, the second through hole 14 can also expose the portion of the main shaft portion 213 exposed by the first through hole 21, so that the first adhesive 40 can achieve a fixed connection between the second support member 50 and the rotating shaft assembly 210, which is beneficial to improving the structural stability of the entire elastic assembly 100; when the opening of the second through hole 14 is smaller than the opening of the first through hole 21, the first through hole 21 can also expose a portion of the upper surface of the first support member 10. In this way, when the second support member 50 is fixed by the first adhesive 40, on the one hand, the opening of the second through hole 14 is relatively small, and the second through hole 14 only partially exposes the flat surface 213a of the shaft assembly 210, so that the first adhesive 40 can achieve the fixed connection between the second support member 50 and the shaft assembly 210 while the first adhesive 40 will not overflow from the second through hole 14 to other components of the shaft assembly 210, thereby effectively avoiding the problem of other components adhering to each other due to the overflow of the first adhesive 40; on the other hand, the first through hole 21 The opening is larger than the opening of the second through hole 14, so that the second support member 50 can be directly fixedly connected to the hinge assembly 210 through the first adhesive 40, and can also be fixedly connected to the upper surface of the first support member 10 through the first adhesive 40, so as to increase the fixing area of ​​the first adhesive 40 and the first support member 10, thereby effectively improving the connection stability between the second support member 50 and the hinge assembly 210 while also improving the connection stability between the second support member 50 and the first support member 10, which is beneficial to improving the overall structural stability of the electronic device 1000.

[0139] In other embodiments, the first support member 10 may not be provided with the second through hole 14. In this case, the first through hole 21 of the first elastic member 20 may only expose a portion of the surface of the first support member 10. The second support member 50 may be fixedly connected to the portion of the surface of the first support member 10 exposed by the first through hole 21 using the first adhesive 40.

[0140] Figure 16a is a schematic diagram of the exploded structure of the screen 300, second elastic member 70, and third adhesive 80 of the electronic device 1000 shown in Figure 3 after being turned upside down. Figure 16b is a schematic diagram of the assembled structure of the screen 300, second elastic member 70, and third adhesive 80 shown in Figure 16a.

[0141] As shown in Figures 16a and 16b, screen 300 may include a flexible display screen 301 and a carrier plate 302 for supporting flexible display screen 301. Carrier plate 302 may be located on the non-display side of flexible display screen 301 and fixedly connected to flexible display screen 301 (Figure 3 also schematically illustrates flexible display screen 301 and carrier plate 302 of screen 300). The flexible display screen 301 is bendable, and the carrier plate 302 is bendable and has a certain structural strength, so that screen 300 can be both unfolded and folded, while also having a certain structural strength, thereby having high structural reliability.

[0142] For example, the screen 300 may include a first portion 310, a second portion 320, and a third portion 330. The second portion 320 may be connected between the first portion 310 and the third portion 330. When the screen 300 is flattened, the first portion 310, the second portion 320, and the third portion 330 may be arranged sequentially along a first direction. It should be noted that in both Figures 16a and 16b, the first portion 310, the second portion 320, and the third portion 330 of the screen 300 are schematically demarcated by dotted lines. For ease of understanding, the volume of the second portion 320 indicated by the dotted line is slightly larger than the actual volume of the second portion 320.

[0143] For example, the portion of the supporting plate 302 located in the second portion 320 may be provided with a plurality of strip-shaped holes 302a. The extension directions of the plurality of strip-shaped holes 302a may be the same. The length extension direction of the plurality of strip-shaped holes 302a may be the same as the length extension direction of the hinge assembly 210. In this way, the plurality of strip-shaped holes 302a can effectively reduce the rigidity of the portion of the supporting plate 302 located in the second portion 320. When the electronic device 1000 is bent, the portion of the supporting plate 302 located in the second portion 320 can be better bent, which is conducive to improving the opening and closing experience of the electronic device 1000. In some embodiments, the portion of the supporting plate 302 located in the first portion 310 close to the second portion 320 may also be provided with a plurality of strip-shaped holes 302a. The portion of the supporting plate 302 located in the third portion 330 close to the second portion 320 may also be provided with a plurality of strip-shaped holes 302a. Thus, strip-shaped holes 302a may be provided on both sides of the second portion 320 of the screen 300, thereby further reducing the rebound force when the second portion 320 is bent, thereby improving the opening and closing experience of the electronic device 1000. In some embodiments, to reduce the rebound force when the second portion 320 is bent and improve the opening and closing experience of the electronic device 1000, strip grooves may be provided on both sides of the second portion 320, and the length extension direction of the strip grooves may be the same as the length extension direction of the hinge assembly 210.

[0144] As shown in Figures 16a and 16b, the material of the second elastic member 70 can be an elastic material or a non-Newtonian fluid material. The thickness of the second elastic member 70 can be greater than or equal to the thickness of the second support member 50 (see Figure 15a). The thickness of the second elastic member 70 can be in the range of 0.02 mm to 0.15 mm. For example, the thickness of the first elastic member 20 can be 0.03 mm, 0.042 mm, 0.075 mm, 0.1 mm, or 0.12 mm.

[0145] For example, the second elastic member 70 can be fixedly connected to the surface of the carrier plate 302 facing away from the flexible display screen 301 by means of the third adhesive 80. In this case, the second elastic member 70 and the screen 300 can be respectively located on opposite sides of the third adhesive 80. The screen 300, the second elastic member 70, and the third adhesive 80 can be assembled together to form the screen assembly 400. The second elastic member 70 and the third adhesive 80 can have the same shape and size. The second elastic member 70 can be roughly rectangular. The width of the second elastic member 70 can be greater than or equal to the width of the second portion 320 of the screen 300. In this case, the second elastic member 70 can overlap with the second portion 320 of the screen 300 in the thickness direction of the electronic device 1000, that is, the third adhesive 80 can also overlap with the second portion 320 of the screen 300 in the thickness direction of the electronic device 1000. When the electronic device 1000 is in the unfolded state, the second elastic member 70 can also cover the multiple strip-shaped holes 302a of the supporting plate 302 in the thickness direction of the electronic device 1000. That is, the third adhesive 80 can cover the multiple strip-shaped holes 302a of the supporting plate 302 in the thickness direction of the electronic device 1000. In this way, the second elastic member 70 and the third adhesive 80 can enhance the rigidity of the portion of the supporting plate 302 provided with the strip-shaped holes 302a (in this embodiment, the portion of the supporting plate 302 located in the second portion 320), thereby effectively preventing the electronic device 1000 from falling in the unfolded state, which would cause the portion of the supporting plate 302 provided with the strip-shaped holes 302a to bulge, and thus cause the second portion 320 of the screen 300 to bulge. This helps to improve the overall structural strength of the screen 300 and extend the service life of the screen 300.

[0146] FIG17 is a schematic diagram of a partial cross-sectional structure of a partial structure of the electronic device 1000 shown in FIG1 taken along line AA in one embodiment.

[0147] As shown in Figure 17, the second adhesive 60 can be roughly strip-shaped. The second adhesive 60 can be located above the second support member 50 and fixedly connected to the second support member 50. The second adhesive 60 can be an adhesive with a certain degree of deformation ability, such as a hot melt adhesive. For example, the projection of the second adhesive 60 in the thickness direction of the electronic device 1000 can at least partially overlap with the flat surface 213a of the hinge assembly 210. The width of the second adhesive 60 can be smaller than the width of the second support member 50.

[0148] For example, the width of the second adhesive 60 can be less than or equal to the opening width of the first through hole 21 of the first elastic member 20. In this way, the majority of the second adhesive 60 can be located directly above the main shaft portion 213 of the hinge assembly 210. The narrow width of the second adhesive 60 can effectively reduce the rebound force when the second adhesive 60 is bent, thereby improving the opening and closing experience of the electronic device 1000.

[0149] In some embodiments, the width of the second adhesive 60 may be equal to the width of the flat surface 213a of the shaft assembly 210. Equal may be completely equal or approximately equal, for example, the width of the second adhesive 60 may be slightly larger or slightly smaller than the width of the flat surface 213a.

[0150] Figure 18a is a schematic diagram of a partial cross-section of the electronic device 1000 shown in Figure 1 taken along line AA in one embodiment. Figure 18b is a schematic diagram of a partial cross-section of the electronic device 1000 shown in Figure 1 taken along line AA in one embodiment. Figure 18b omits the screen 300 compared to Figure 18a.

[0151] As shown in Figures 17 to 18b, the first part 310 of the screen 300 can be located above the first shell 220 and fixedly connected to the first adhesive 240. The third part 330 of the screen 300 can be located above the second shell 230 and fixedly connected to the second adhesive 250. Figure 4 also illustrates the first adhesive 240 and the second adhesive 250 from another perspective. At this time, the flexible display screen 301 can be located on the side of the carrier plate 302 facing away from the hinge assembly 210. The surface of the second elastic member 70 facing away from the third adhesive 80 can be fixedly connected to the second adhesive 60. When the electronic device 1000 is in the open state, the second part 320 of the screen 300, the elastic component 100 and the hinge assembly 210 can be stacked along the thickness direction of the electronic device 1000.

[0152] Exemplarily, the elastic component 100 may include a first portion 101, a second portion 102, and a third portion 103. The third portion 103 may be connected between the first portion 101 and the second portion 102. When the electronic device 1000 is in an open state, the first portion 101, the third portion 103, and the second portion 102 may be arranged in sequence along a first direction. The first portion 101 of the elastic component 100 may overlap the first connecting portion 211 of the hinge assembly 210. The second portion 102 of the elastic component 100 may overlap the second connecting portion 212 of the hinge assembly 210. The third portion 103 of the elastic component 100 may be fixedly connected to the main shaft portion 213 of the hinge assembly 210. It should be understood that the first portion 101, the second portion 102, and the third portion 103 of the elastic component 100 are schematically divided by dotted lines in Figure 18b.

[0153] It will be appreciated that, compared to sequentially stacking and securing the second elastic member 70, the third adhesive 80, and the screen 300 on the second adhesive 60, in this embodiment, the second elastic member 70, the third adhesive 80, and the screen 300 are first assembled together to form the screen assembly 400, and then the entire screen assembly 400 is secured to the second adhesive 60. This provides a relatively flat support environment for the screen 300 during the assembly of the second elastic member 70 and the third adhesive 80, making it easier to assemble the second elastic member 70 and the third adhesive 80 on the screen 300. This also helps reduce bubbles in the third adhesive 80, thereby effectively improving the connection stability between the second elastic member 70, the third adhesive 80, and the screen 300. This also effectively prevents debonding and delamination between the second elastic member 70 and the third adhesive 80, or between the screen 300 and the third adhesive 80, at bubbles caused by repeated opening and closing of the electronic device 1000. This improves the overall structural stability of the electronic device 1000 and extends its service life. In other words, the screen assembly 400 in this embodiment may include at least one elastic member.

[0154] In other embodiments, the second support member 50 and the second adhesive 60 may be first assembled with the screen 300, the second elastic member 70, and the third adhesive 80 to form the screen assembly 400. The entire screen assembly 400 is then secured to the other components of the electronic device 1000. In other words, the screen assembly 400 in this embodiment may further include at least one support member.

[0155] Referring again to Figures 18a and 18b, when the electronic device 1000 is in the open state, the screen 300 and the elastic member 100 can be relatively flattened by the housing device 200. The first support member 10, the first elastic member 20, the second support member 50, and the second elastic member 70 can all be located above the flat surface 213a of the hinge assembly 210 and arranged sequentially along the housing device 200 toward the screen 300.

[0156] Exemplarily, at least a portion of the elastic component 100 can be located within the first mounting groove 221, that is, within the receiving space 200a (see FIG4 ). The sum of the thickness of the elastic component 100 and the thickness of the shaft component 210 can be equal to the first distance H1. That is, the surface of the elastic component 100 facing away from the shaft component 210 (that is, the surface of the third adhesive 80 facing away from the shaft component 210 in this embodiment) can be flush with the upper surface of the first back glue 240. It should be noted that the sum of the thickness of the elastic component 100 and the thickness of the shaft component 210 can be equal to the first distance H1, which can be understood as being completely equal or approximately equal, that is, the sum of the thickness of the elastic component 100 and the thickness of the shaft component 210 and the first distance H1 can have a certain error, for example, the error can be within the range of plus or minus 0.1 mm.

[0157] The first elastic member 20 and the second elastic member 70 may together constitute the elastic portion of the elastic assembly 100. The total thickness of the elastic portion may be in the range of 0.2 mm to 0.4 mm. The first support member 10 and the second support member 50 may together constitute the supporting portion of the elastic assembly 100. The total thickness of the supporting portion may be less than or equal to the total thickness of the elastic portion.

[0158] Figure 19a is a schematic diagram of a partial cross-section structure of the electronic device 1000 shown in Figure 2 taken along line BB in one embodiment. Figure 19b is a schematic diagram of a partial cross-section structure of the electronic device 1000 shown in Figure 2 taken along line BB in one embodiment.

[0159] As shown in Figures 19a and 19b, when the electronic device 1000 is in the closed state, the screen 300 and the elastic component 100 can be folded relative to each other under the influence of the housing device 200. The second portion 320 of the screen 300 can be bent relative to each other into an arc shape. The elastic component 100 can be located between the second portion 320 of the screen 300 and the main shaft portion 213 of the housing device 200. Specifically, the first portion 101 of the elastic component 100 can overlap the first connecting portion 211 of the hinge assembly 210. The second portion 102 of the elastic component 100 can overlap the second connecting portion 212 of the hinge assembly 210.

[0160] Specifically, the second adhesive 60 of the elastic component 100 can deform to a certain extent under the pressure of the screen 300. The left and right sides of the second adhesive 60 are compressed in the direction close to the hinge assembly 210, so that the surface of the second adhesive 60 facing away from the hinge assembly 210 can bend into an arc shape, thereby better fitting the bent screen 300, so that the elastic component 100 can provide a smoother support environment for the screen 300. In some embodiments, the left and right sides of the first adhesive 40 can also be compressed in the direction close to the hinge assembly 210, so that the surface of the first adhesive 40 facing away from the hinge assembly 210 can bend into an arc shape, thereby better fitting the bent screen 300.

[0161] It will be appreciated that, compared to conventional electronic devices that sacrifice screen thickness to improve overall structural reliability, resulting in a thicker overall thickness and greater rebound force when bent, the electronic device 1000 of this embodiment incorporates an elastic component 100 between the screen 300 and the main shaft portion 213 of the hinge assembly 210. The elastic component 100 may include a supporting portion and an elastic portion. The supporting portion may be made of a rigid material, while the elastic portion may be made of an elastic material or a non-Newtonian fluid. When the electronic device 1000 is closed, the hinge assembly 210 may be located inside the screen 300, with the elastic component 100 secured between the second portion 320 of the screen 300 and the main shaft portion 213 of the hinge assembly 210. When the electronic device 1000 is open, the screen 300, the elastic component 100, and the hinge assembly 210 may be stacked along the thickness of the electronic device 1000. In this way, when the electronic device 1000 falls, particularly when the electronic device 1000 is closed, the supporting portion of the elastic assembly 100 can effectively absorb the impact and / or compressive force exerted by the hinge assembly 210 on the screen 300, reducing the impact force on the screen 300 and providing good rigid support for the screen 300. The elastic portion of the elastic assembly 100 can effectively resist the impact and / or compressive force exerted on the screen 300, while also absorbing and dissipating the impact and / or compressive force on the screen 300. The elastic assembly 100 can effectively absorb the impact force exerted on the second portion 320 of the screen 300 due to a fall, preventing the second portion 320 of the screen 300 from strongly colliding with the hinge assembly 210, thereby improving the structural reliability of the screen 300 and extending its service life. In other words, the screen 300 in this embodiment does not need to sacrifice its own thickness. The elastic component 100 located between the screen 300 and the hinge component 210 can effectively improve the reliability of the screen 300 when it falls. At the same time, the overall thickness of the screen 300 is relatively thin, which can effectively reduce the rebound force when the electronic device 1000 is bent, which is beneficial to improving the user's opening and closing experience.

[0162] Secondly, the supporting portion of the elastic component 100 may include at least one supporting member (also referred to as the first supporting member 10 in this embodiment). The elastic portion of the elastic component 100 may include at least one elastic member (also referred to as the first elastic member 20 in this embodiment). The first supporting member 10 may be made of a rigid material, and the first elastic member 20 may be made of an elastic material or a non-Newtonian fluid material. Thus, when the electronic device 1000 falls and the second portion 320 of the screen 300 is impacted, the first supporting member 10 can effectively absorb the impact force and / or squeezing force exerted by the hinge assembly 210 on the second portion 320 of the screen 300, reducing the impact force on the screen 300 and providing good rigid support for the screen 300. The first elastic member 20 can effectively act as an elastic force against the impact force and / or squeezing force exerted on the screen 300, while also absorbing and dispersing the impact force and / or squeezing force exerted on the screen 300. In other words, the elastic component 100 of this embodiment includes a first support member 10 and a first elastic member 20. The first support member 10 and the first elastic member 20 respectively provide good rigid protection and elastic protection for the screen 300. The entire elastic component 100 has strong impact resistance and extrusion resistance, so that the elastic component 100 can better protect the screen 300, improve the falling reliability of the screen 300, and help extend the service life of the screen 300.

[0163] In addition, the elastic assembly 100 in this embodiment may further include a second support member 50 and a second elastic member 70. The first support member 10, the first elastic member 20, the second support member 50, and the second elastic member 70 may be sequentially arranged along the direction from the rotating shaft assembly 210 toward the screen 300 and arranged in a stacked manner. The first support member 10 and the second support member 50 may collectively constitute the support portion of the elastic assembly 100. The first elastic member 20 and the second elastic member 70 may collectively constitute the elastic portion of the elastic assembly 100. Thus, by alternately stacking the multiple support members (in this embodiment, the first support member 10 and the second support member 50) and the multiple elastic members (in this embodiment, the first elastic member 20 and the second elastic member 70) in the elastic assembly 100, the entire elastic assembly 100 can be formed into a structure similar to a bulletproof vest, which helps improve the elastic assembly 100's impact resistance and compression resistance. Compared to directly increasing the thickness of the first support member 10 and the first elastic member 20 to improve the impact resistance and compression resistance of the elastic assembly 100, the elastic assembly 100 in this embodiment has better impact resistance and compression resistance under conditions of equivalent thickness. Under conditions of equivalent performance, each support member and each elastic member of the elastic assembly 100 in this embodiment is relatively thin, and the multiple support members and elastic members are secured to each other by an adhesive layer. This allows for a certain degree of offset between adjacent support members and elastic members when the electronic device 1000 is bent, significantly reducing the rebound force of the entire elastic assembly 100 when bending. In other words, while ensuring certain performance conditions, the thickness of the elastic assembly 100 in this embodiment can be even thinner, which facilitates the thinning design of the electronic device 1000. Furthermore, the total thickness of the elastic portion of the elastic assembly 100 in this embodiment can be within a range of 0.2 mm to 0.4 mm, and the total thickness of the support portion can be less than or equal to the total thickness of the elastic portion. In this way, the elastic component 100 can have good impact resistance and extrusion resistance while having a relatively thin total thickness, which is conducive to achieving a thin design of the electronic device 1000.

[0164] In addition, the elastic assembly 100 in this embodiment includes a first support member 10, a first elastic member 20, a second support member 50, and a second elastic member 70. The first support member 10, the first elastic member 20, the second support member 50, and the second elastic member 70 can be arranged sequentially along the hinge assembly 210 toward the screen 300 and arranged in a stacked manner. Thus, compared to a case where the support member is disposed adjacent to the screen 300, where the support member experiences a greater rebound force when bent, which can easily damage the screen 300, this embodiment disposes the elastic member (i.e., the second elastic member 70 in this embodiment) adjacent to the screen 300, resulting in a smaller rebound force when bent. This effectively reduces the chance of damage to the screen 300 during bending and helps extend the service life of the electronic device 1000.

[0165] Furthermore, in this embodiment, when the electronic device 1000 is in the open state, at least a portion of the elastic component 100 can be located within the first mounting groove 221. The sum of the thickness of the elastic component 100 and the thickness of the hinge component 210 can be equal to the height difference (i.e., first distance H1) between the upper surface of the first adhesive backing 240 of the housing assembly 200 and the wall of the first mounting groove 221 facing the screen 300 in the thickness direction of the electronic device 1000. This allows the elastic component 100 to utilize the thickness of the housing assembly 200, ensuring the drop resistance of the screen 300 without increasing the thickness of the entire electronic device 1000, thereby facilitating a thinner design for the electronic device 1000. Furthermore, there is no height difference between the elastic component 100 and either the first adhesive backing 240 or the second adhesive backing 250 of the housing assembly 200, thereby providing a relatively flat support environment for the screen 300, improving the display quality of the screen 300 and enhancing the user experience.

[0166] In some embodiments, the elastic assembly 100 may include a first support member 10, a first elastic member 20, a second support member 50, and a second elastic member 70. The first elastic member 20, the first support member 10, the second elastic member 70, and the second support member 50 may be arranged sequentially along the hinge assembly 210 toward the screen 300 and arranged in a stacked manner. Thus, compared to an elastic member disposed adjacent to the screen 300, the elastic member has limited ability to disperse and / or absorb impact force when the electronic device 1000 falls, which can easily damage the screen 300. In this embodiment, the support member (i.e., the second support member 50 in this embodiment) may be disposed adjacent to the screen 300. This support member can effectively absorb impact force when the electronic device 1000 falls, while also providing good rigid support for the screen 300. This effectively reduces the chance of damage to the screen 300 during a fall, thereby extending the service life of the electronic device 1000.

[0167] In other embodiments, the elastic component 100 may further include a third support member. The third support member may constitute part of the support portion of the elastic component 100. The third support member may be fixed between the third adhesive 80 and the screen 300. Alternatively, the elastic component 100 may further include a third elastic member. The third elastic member may constitute part of the elastic portion of the elastic component 100. The third elastic member may be fixed between the first support member 10 and the hinge assembly 210. Alternatively, the elastic component 100 may further include both a third support member and a third elastic member. The third support member and the third elastic member may be fixed together between the third adhesive 80 and the screen 300. In this case, the first support member 10, the first elastic member 20, the second support member 50, the second elastic member 70, the third support member, and the third elastic member may be arranged sequentially along the thickness direction of the electronic device 1000 and arranged in a stacked manner. This application does not specifically limit the number of support members in the support portion of the elastic component 100 or the number of elastic members in the elastic portion.

[0168] In some other embodiments, the elastic component 100 may not include the second support member 50 , the second elastic member 70 , the second adhesive 60 and the third adhesive 80 , and the first adhesive 40 may directly connect the first support member 10 and the screen 300 .

[0169] FIG20 is a schematic structural diagram of the first support member 10 shown in FIG6 in another embodiment.

[0170] As shown in Figure 20, the structure of the first support member 10 in this embodiment is roughly the same as the structure of the first support member 10 shown in Figure 6, and the identical parts are not repeated here. The difference is that the first support member 10 can also be provided with at least one fourth through hole 15. The fourth through hole 15 can be spaced apart from the solder joint 10a. In this embodiment, the number of the fourth through holes 15 can be two. The solder joint 10a can be located between two fourth through holes 15. One of the fourth through holes 15 can be located between the solder joint 10a and an adjacent second through hole 14. The fourth through hole 15 can be an elongated hole 302a. The extension direction of the fourth through hole 15 can intersect with the extension direction of the first support member 10. For example, the extension direction of the fourth through hole 15 can also be perpendicular to the extension direction of the first support member 10.

[0171] It is understandable that when the electronic device 1000 falls, the screen 300 will slip under the action of inertia, and at the same time, a pulling force will be generated on the elastic component 100. When the pulling force acts on the first support member 10, it is easy to cause the solder joint 10a between the first support member 10 and the hinge assembly 210 to become desoldered due to the pulling force from the screen 300, affecting the contact between the first support member 10 and the main shaft portion 213 of the hinge assembly 210, thereby generating radio frequency interference to the antenna of the electronic device 1000 and affecting the antenna performance of the entire device. In this embodiment, a fourth through hole 15 is provided on the first support member 10, which is spaced apart from the solder joint 10a. In this way, the fourth through hole 15 can block the pulling force from being transmitted to the solder joint 10a, thereby effectively preventing the first support member 10 from becoming desoldered, which is beneficial to ensuring the connection reliability between the first support member 10 and the hinge assembly 210 and reducing the impact on the antenna performance of the entire device.

[0172] FIG21 is a schematic structural diagram of the first support member 10 shown in FIG6 in another embodiment.

[0173] As shown in Figure 21, the structure of the first support member 10 in this embodiment is roughly the same as the structure of the first support member 10 shown in Figure 6, and the identical parts are not repeated here. The differences between the two will be described below. For example, at least one corner of the first support member 10 can also be trimmed to form at least one avoidance space 10c. The avoidance space 10c can be used to avoid the antenna in the electronic device 1000. In this embodiment, the first support member 10 can be roughly in the shape of an elongated strip and have four corners. The four corners can all be trimmed to form four avoidance spaces 10c.

[0174] It can be understood that in this embodiment, the corners of the first support member 10 are trimmed to form an avoidance space 10c, so that the edge of the first support member 10 can be away from the antenna inside the electronic device 1000, thereby reducing the radio frequency interference of the first support member 10 on the antenna inside the electronic device 1000 and reducing the impact of the first support member 10 on the antenna performance of the entire device.

[0175] In some embodiments, the shape and size of the first elastic member 20 can be the same as those of the first support member 10. The shape and size of the lubricating member 30 can also be the same as those of the first support member 10. In other words, both the first elastic member 20 and the lubricating member 30 can be trimmed at each corner. In this way, the first support member 10, the first elastic member 20 and the lubricating member 30 can be assembled together and then trimmed together, which is beneficial to saving preparation processes and reducing dimensional errors. At the same time, the shapes and sizes of the first support member 10, the first elastic member 20 and the lubricating member 30 are consistent, which can effectively avoid the generation of step areas between the first support member 10, the first elastic member 20 and the lubricating member 30, which is beneficial to provide a flat support environment for the screen 300.

[0176] FIG22 is a schematic structural diagram of the first support member 10 shown in FIG6 in another embodiment.

[0177] As shown in FIG22 , the structure of the first support member 10 in this embodiment is substantially the same as that of the first support member 10 shown in FIG6 , and the common parts are not further described. The following mainly describes the differences between the two. The first support member 10 in this embodiment may also be provided with a plurality of first holes 16 and a plurality of second holes 17. The number of first holes 16 may be the same as the number of second holes 17. The plurality of first holes 16 may all be located in the first portion 11 of the first support member 10. The plurality of first holes 16 may be spaced apart along the length of the first support member 10. The plurality of second holes 17 may all be located in the third portion 13 of the first support member 10. The plurality of second holes 17 may all be spaced apart along the length of the first support member 10. The first holes 16 and the second holes 17 may both be elongated holes. The directions in which the first holes 16 and the second holes 17 extend may intersect the length of the first support member 10. In this embodiment, the directions in which the plurality of first holes 16 and the plurality of second holes 17 extend may be perpendicular to the length of the first support member 10.

[0178] It can be understood that in this embodiment, by providing a plurality of first holes 16 whose extension directions intersect with the length extension direction of the first support member 10 on the first part 11 of the first support member 10, and providing a plurality of second holes 17 whose extension directions intersect with the length extension direction of the first support member 10 on the third part 13 of the first support member 10, the rebound force when the first support member 10 is bent can be effectively reduced, which is beneficial to improving the opening and closing experience of the electronic device 1000.

[0179] FIG23 is a schematic structural diagram of the first elastic member 20 shown in FIG8 in another embodiment.

[0180] As shown in Figure 23, the structure of the first elastic member 20 in this embodiment is roughly the same as the structure of the first elastic member 20 shown in Figure 8, and the identical parts will not be repeated here. The following mainly introduces the differences between the two. The first elastic member 20 in this embodiment may include a first end 22 and a second end 23 that are arranged opposite to each other. The first end 22 and the second end 23 may be provided with a plurality of grooves 24. Taking the first end 22 as an example, the plurality of grooves 24 may be arranged at intervals. The opening of the groove 24 may be arranged facing away from the second end 23. At this time, the first end 22 may be roughly serrated or wavy. The setting of the second end 23 is the same as that of the first end 22, and will not be repeated here.

[0181] It can be understood that in this embodiment, by providing one or more grooves 24 at the first end 22 and the second end 23 of the first elastic member 20, a release space can be provided in case the electronic device 1000 falls in the open state, which causes the first elastic member 20 to arch at its ends (that is, the first end 22 and the second end 23). This can effectively avoid the problem that when the electronic device 1000 falls in the open state, the first elastic member 20 arches at the edges of its ends, causing the screen 300 to arch, resulting in the wiring of the screen 300 being broken and causing the screen 300 to fail. This is beneficial to extending the service life of the screen 300 and improving user experience.

[0182] In other embodiments, as shown in FIG24 , the first end portion 22 may also be provided with only one arc-shaped groove 24. In this case, the first end portion 22 may be substantially arc-shaped. The present application does not specifically limit the shape and number of the grooves 24.

[0183] It should be noted that, in the absence of conflict, the features in the embodiments of this application can be combined with each other, and any combination of features in different embodiments is also within the scope of protection of this application. That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0184] It should be noted that all the above drawings are for illustrative purposes only and do not represent the actual size of the product. Furthermore, the dimensional ratios between the components in the drawings are not intended to limit the actual product of the present application.

[0185] The above are only some of the embodiments of this application, and the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
