Description

Technical Field

[0001] This application relates to the field of foldable electronic products, and more particularly to a foldable electronic device and a screen assembly. Background Technology

[0002] With the continuous development of flexible display technology, it has been widely used in various foldable electronic devices. Among them, outward-folding electronic devices are favored by users due to their greater convenience. However, whether in the open or closed state, the screen of outward-folding electronic devices is exposed to the external environment, greatly increasing the probability of screen damage when the electronic device is dropped.

[0003] Traditional outward-folding electronic devices typically improve drop reliability by sacrificing screen thickness. However, while increasing screen thickness enhances drop reliability, it also significantly increases the rebound force when the screen bends, resulting in a poor opening and closing experience. Therefore, developing an electronic device with high drop reliability and low rebound force has become a current research focus. Summary of the Invention

[0004] This application provides a foldable electronic device, which aims to provide a foldable electronic device and screen assembly with high screen drop reliability and low rebound force.

[0005] 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 component. The screen is fixedly connected to the first housing and the second housing. The hinge assembly includes a first connecting portion, a second connecting portion, and a main shaft portion. The main shaft portion connects the first connecting portion and the second connecting portion. The first connecting portion connects to the first housing. The second connecting portion connects to the second housing. The elastic component includes an elastic portion and a supporting portion. The elastic portion is made of an elastic material or a non-Newtonian fluid material. The supporting 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 component is flattened. The screen, the elastic component, and the hinge assembly are stacked along the thickness direction of the electronic device. The elastic portion and the supporting portion are stacked along the thickness direction of the electronic device. A first portion of the elastic component overlaps with the first connecting portion, and a second portion of the elastic component overlaps with the second connecting portion. When the electronic device is in the closed state, the elastic component bends, with the first portion of the elastic component overlapping the first connecting portion, and the second portion of the elastic component overlapping the second connecting portion.

[0006] Understandably, compared to traditional electronic devices that sacrifice screen thickness to improve overall structural reliability, resulting in a thicker overall device and greater rebound force when bent, the electronic device in this embodiment incorporates an elastic component between the screen and the main shaft of the hinge assembly. This elastic component can include a support portion and an elastic portion. The support portion can be made of a rigid material, while the elastic portion can be made of an elastic material or a non-Newtonian fluid material. When the electronic device is in the open state, the screen, elastic component, and hinge assembly are stacked along the thickness direction of the electronic device. Thus, when the electronic device is dropped, the support portion of the elastic component can effectively absorb the impact and / or compressive force exerted on the screen by the hinge assembly, reducing the impact force on the screen and providing good rigid support. The elastic portion of the elastic component provides good elasticity against the impact and / or compressive force applied to the screen, and also absorbs and disperses the impact and / or compressive force on the screen. The elastic component effectively absorbs the impact force on the screen from drops, preventing the screen from developing bright spots and black spots due to strong collisions with the hinge assembly. This improves the structural reliability of the screen and extends its lifespan. In other words, the screen in this embodiment does not need to sacrifice its own thickness; the elastic component located between the screen and the hinge assembly effectively improves the screen's reliability during drops. Simultaneously, the overall screen thickness is relatively thin, effectively reducing the rebound force when the electronic device is bent, thus improving the user's opening and closing experience.

[0007] 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 part, a second part, and a third part. The second part is connected between the first part and the third part. The second part is fixedly connected to the main shaft portion. When the electronic device is in the open state, the first part overlaps with the first connecting part and is movable relative to the first connecting part. The second part is flattened relative to the first part, and the third part overlaps with the second connecting part and is movable relative to the second connecting part.

[0008] It is understood that the supporting portion of the elastic component in this embodiment may include at least one support member (i.e., the first support member in this embodiment). The elastic portion of the elastic component may include at least one elastic member (i.e., 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 material. Thus, when the electronic device is dropped and the second part of the screen is impacted, the first support member can effectively absorb the impact force and / or compressive force from the hinge assembly on the second part of the screen, reducing the impact force on the screen and providing good rigid support. The first elastic member can provide good elasticity against the impact force and / or compressive force applied to the screen, while also absorbing and dispersing the impact force and / or compressive force. In other words, the elastic component in this embodiment includes both a first support member and a first elastic member. The first support member and the first elastic member provide good rigid protection and elastic protection for the screen, respectively. The entire elastic component has strong impact resistance and compression resistance, enabling it to better protect the screen, improve the screen's drop reliability, and extend the screen's lifespan.

[0009] 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 bends relative to the first part, and the third part moves relative to the second connecting part. Thus, regardless of whether the electronic device is in an open or closed state, the first support member can cover the gaps between the main shaft portion of the rotating assembly and the first connecting part, and between the main shaft portion of the rotating assembly and the second connecting part, in the thickness direction of the electronic device. This prevents the outer edge of the first support member from interfering with the rotating assembly due to its location at the gaps, thus avoiding interference with the opening and closing of the electronic device. Simultaneously, the first support member can overlap the first and second connecting parts, providing a relatively flat support environment for the subsequent fixed assembly of components.

[0010] In one possible implementation, the spindle portion has a flat surface. This flat surface faces the screen, and a second portion of the first support is fixedly connected to the flat surface. When the electronic device is in the open state, the flat surface is parallel to the screen. Thus, the spindle portion of the hinge assembly has a relatively flat surface, facilitating the fixation between the elastic component and the spindle portion.

[0011] In one possible implementation, the thickness of the first support member is less than or equal to the thickness of the first elastic member. This thinner first support member helps reduce the rebound force when the electronic device is bent, thereby improving the opening and closing experience.

[0012] In one possible implementation, the first elastic member has 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 within the first through hole and connects the first support member and the screen. In this way, the first adhesive can utilize the thickness of the first elastic member, thereby achieving the fixation of other components without increasing the thickness of the elastic component, which is beneficial for achieving a thinner design of the electronic device. Simultaneously, the through hole on the first elastic member (i.e., the first through hole in this embodiment) can be used to control the thickness of the first adhesive, thereby avoiding the problem of insufficient connection stability of other components due to excessively thin first adhesive, and avoiding the problem of uneven screen due to excessively thick first adhesive.

[0013] In one possible implementation, the first support member has at least one second through hole. The second through hole exposes a portion of the main shaft portion. The second through hole communicates with the first through hole. The opening size of the second through hole is not 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 within the second through hole and the first through hole, and connects a portion of the main shaft portion, a portion of the first support member, and a portion of the screen.

[0014] It is understood that the opening of the second through hole of the first support member in this embodiment may not be larger than the opening of the first through hole of the first elastic member. When the opening of the second through hole is the same size as the opening of the first through hole, the second through hole can also expose part of the main shaft portion exposed by the first through hole, so that the first adhesive can achieve the fixed connection between other components and 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 part of the upper surface of the first support member. In this way, when the second support is fixed by the first adhesive, on the one hand, the opening of the second through hole is small, and the second through hole only exposes part of the flat surface a of the rotating shaft assembly. This allows the first adhesive to achieve a fixed connection between the second support and the rotating shaft assembly without overflowing from the second through hole onto other parts of the rotating shaft assembly. This effectively avoids the problem of other parts sticking together 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. This allows the second support to be directly fixed to the rotating shaft assembly by the first adhesive, and also to be fixed to the upper surface of the first support by the first adhesive. This increases the fixing area between the first adhesive and the first support, thereby effectively improving the connection stability between the second support and the rotating shaft assembly, as well as the connection stability between the second support and the first support, which is beneficial to improving the overall structural stability of the electronic device.

[0015] In one possible implementation, the support portion further includes a second support member. When the electronic device is in the open state, the second support member is stacked between the first elastic member and the screen in the thickness direction of the electronic device. This increases the number of support members in the elastic component, allowing the entire support portion to better absorb the impact and / or compressive forces exerted on the screen by the hinge assembly, reducing the impact force on the screen and providing good rigid support. This improves the reliability of the screen during drops and extends the lifespan of the electronic device.

[0016] In one possible implementation, when the electronic device is in the open state, the gap between the first connecting part and the second connecting part is wider than or equal to the width of the second support member in the first direction. This results in a narrower second support member, effectively reducing the rebound force when the second support member bends, making the opening and closing of the electronic device smoother and improving the user experience.

[0017] In one possible implementation, the elastic component further 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 layered between the second support member and the screen along the thickness direction of the electronic device. When the electronic device is in the open state, the direction from the first housing to the second housing is a first direction, and in this first direction, the width of the second adhesive is less than or equal to the width of the second support member. Thus, most of the second adhesive can be located directly above the main shaft portion of the hinge assembly, and the narrower width of the second adhesive effectively reduces the rebound force when the second adhesive bends, improving the opening and closing experience of the electronic device.

[0018] In one possible implementation, the elastic component 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 sequentially along the direction from the pivot assembly toward the screen.

[0019] It is understood that the elastic component 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 can be arranged sequentially and stacked along the direction of the rotating assembly toward the screen. The first support member and the second support member can together constitute the support portion of the elastic component. The first elastic member and the second elastic member can together constitute the elastic portion of the elastic component. Thus, by alternately stacking and arranging multiple support members (i.e., the first and second support members in this embodiment) and multiple elastic members (i.e., the first and second elastic members in this embodiment) in the elastic component, the entire elastic component can form a structure similar to a bulletproof vest, which is beneficial for improving the impact resistance and compression resistance of the elastic component. Compared to directly increasing the thickness of the first support member and the first elastic member to improve the impact resistance and compression resistance of the elastic component, the elastic component in this embodiment has better impact resistance and compression resistance under the same thickness conditions. Under the same performance conditions, the thickness of each support member and each elastic member in the elastic component of this embodiment is relatively thin, and multiple support members and multiple elastic members are fixed to each other by adhesive layers. In this way, when the electronic device is bent, a certain degree of misalignment can occur between adjacent support members and elastic members, thereby greatly reducing the rebound force of the entire elastic component when bent. In other words, while ensuring certain performance conditions, the thickness of the elastic component in this embodiment can be thinner, which is beneficial for achieving a thinner 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 0.1 mm to 0.1 mm, and the total thickness of the support part can be less than or equal to the total thickness of the elastic part. Thus, the elastic component can have good impact resistance and compression resistance while maintaining a thin overall thickness, which is beneficial for achieving a thinner design of the electronic device.

[0020] Secondly, compared to a support member that is 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 set adjacent to the screen. The elastic member has a smaller rebound force when bent, which can effectively reduce the probability of the screen being damaged when bent and help extend the service life of electronic devices.

[0021] In one possible implementation, the supporting portion includes a first supporting member and a second supporting member. The elastic portion includes a first elastic member and a second elastic member. The first elastic member, the first supporting member, the second elastic member, and the second supporting member are arranged sequentially along the direction from which the rotating shaft assembly points towards the screen.

[0022] It is understood that the elastic component in this embodiment may simultaneously include a first support member, a first elastic member, a second support member, and a second elastic member, and the first elastic member, the first support member, the second elastic member, and the second support member may be arranged sequentially and stacked along the direction of the rotating assembly toward the screen. In this way, compared to an elastic member being adjacent to the screen, the elastic member has limited ability to disperse and / or absorb impact when the electronic device is dropped, making the screen more susceptible to damage. This embodiment, by providing a support member (i.e., the second support member in this embodiment) that can be adjacent to the screen, allows the support member to better absorb impact when the electronic device is dropped, while also providing good rigid support for the screen, thereby effectively reducing the probability of screen damage during drops and extending the lifespan of the electronic device.

[0023] In one possible implementation, the elastic component further includes a third adhesive. The third adhesive connects the second elastic element and the screen. When the electronic device is in the open state, in a first direction, the width of the third adhesive is equal to the width of the second elastic element. Thus, the third adhesive can secure the second elastic element to the screen while minimizing its impact on the rebound force when the electronic device is bent, thereby improving the opening and closing experience.

[0024] In one possible implementation, the screen includes a first part, a second part, and a third part arranged sequentially along a first direction. The first part is connected to a first housing. The third part is connected to a second housing. The second part is connected between the first and third parts. When the electronic device is in the open state, the screen is flattened, and the first, second, and third parts are arranged sequentially along the first direction. In the thickness direction of the electronic device, the second part is stacked with a hinge assembly. 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 the closed state, the first and third parts 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 screen from arching when the electronic device is in the open state, which is beneficial to improving the overall structural strength of the screen and extending its service life.

[0025] In one possible implementation, the elastic component further includes a lubricant. The lubricant is fixedly connected to the surface of the first elastic element facing away from the first support. Thus, by providing a lubricant, the coefficient of friction between the first elastic element and other components located above it can be effectively reduced, which helps improve the opening and closing experience of the electronic device.

[0026] 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 extension portion. The second bent portion includes a second connecting portion and a second extension portion. When the electronic device is in the open state, the first extension portion and the main body portion are spaced apart along the thickness direction of the electronic device. The second extension portion and the main body portion are also spaced apart along the thickness direction of the electronic device. The first and second extension portions are located on the side of the main body portion facing the rotating shaft assembly. The first and second extension portions are spaced apart. The first connecting portion connects the main body portion and the first extension portion. The second connecting portion connects the main body portion and the second extension portion. The main body portion, the first connecting portion, and the first extension portion form a first semi-enclosed accommodating space. The main body portion, the second connecting portion, and the second extension portion form a second semi-enclosed accommodating space. A portion of the first elastic member and at least a portion of the first support member, a first portion, are located in the first semi-enclosed accommodating space. A portion of the first elastic member and at least a portion of the first support member, a third portion, are located in the second semi-enclosed accommodating space.

[0027] Understandably, compared to having two lubricants respectively on the surface of the first support member facing away from the first elastic member and 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 lubricant in this embodiment can have a main body covering the surface of the first elastic member facing away from the first support member, as well as a first bent portion bending towards a first part of the first support member and a second bent portion bending towards a third part of the first support member. In this way, the lubricant can not only simultaneously cover the surface of the first elastic member, a portion of the surface of the first part of the first support member, and a portion of the surface of the third part of the first support member, but also wrap around the outer edges of the first elastic member and the first support member. This allows the lubricant to protect the outer edges of the first elastic member and the first support member, preventing them from scratching other components and causing abnormal noise. At the same time, the first support member is relatively thin, and its outer edge is relatively sharp. By setting a lubricant to wrap around the outer edge of the first support (in this embodiment, that is, the edge of the first part of the first support away from the third part and the edge of the third part away from the first part), it is possible to effectively prevent the edge of the first support from scratching the assembly personnel during the installation of the first support with other components, which is beneficial to improving the safety of the assembly process.

[0028] In one possible implementation, when the electronic device is in the open state, the main body, the first elastic member, the first portion of the first support member, and the first extension are sequentially stacked in the thickness direction of the electronic device. A first connecting portion is located 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 sequentially stacked. A second connecting portion is located 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 lubricant can effectively wrap around the outer edge of the first support member, thereby effectively preventing the outer edge of the first support member from scratching other components and causing abnormal noise.

[0029] In one possible implementation, the first elastic member extends along its length by including a first end and a second end disposed opposite to each other. The first end has at least one groove. The opening direction of the groove is the direction from the second end to the first end.

[0030] It is understood that by providing one or more grooves at the first and second ends of the first elastic member in this embodiment, a release space can be provided for the arching of the first elastic member at its ends (i.e., the first and second ends) caused by the electronic device falling when it is in the open state. This can effectively avoid the phenomenon that the first elastic member arches at the edge of its ends when it falls when the electronic device is in the open state, which would cause the screen to arch and the screen wiring to break, resulting in screen failure. This is beneficial to extending the service life of the screen and improving the user experience.

[0031] In one possible implementation, a first portion of the first support member has a plurality of first holes. These first holes are spaced apart along the length extension direction of the first support member. A third portion of the first support member has a plurality of second holes, which are also spaced apart along the length extension direction of the first support member. The length extension directions of both the first and second holes intersect the length extension direction of the first support member.

[0032] It is understood that by providing multiple first holes in the first part of the first support member whose extension direction intersects with the length extension direction of the first support member, and providing multiple second holes in the third part of the first support member whose extension direction intersects with the length extension direction of the first support member, the rebound force when the first support member is bent can be effectively reduced, which is beneficial to improving the opening and closing experience of electronic devices.

[0033] In one possible implementation, the first support member is elongated. At least one corner of the first support member has clearance space.

[0034] It is understood that in this embodiment, by cutting off the corner of the first support member to form an avoidance space c, the edge of the first support member can be kept away from the antenna inside the electronic device, thereby reducing the radio frequency interference of the first support member to the antenna inside the electronic device and reducing the impact of the first support member on the antenna performance of the whole device.

[0035] In one possible implementation, the thickness of the supporting portion is less than or equal to the thickness of the elastic portion. This allows the total thickness of the supporting portion to be less than or equal to the total thickness of the elastic portion. Consequently, the elastic component can possess good impact and compression resistance while maintaining a relatively thin overall thickness, which is beneficial for achieving slimmer designs in electronic devices.

[0036] In one possible implementation, the hinge assembly is located inside the screen. This allows the electronic device to be an inward-folding device. When the electronic device is dropped, especially when it is in a closed position, the supporting portion of the elastic component can effectively absorb the impact and / or compressive force of the hinge assembly on the screen, reducing the impact force on the screen and providing good rigid support. The elastic portion of the elastic component can effectively absorb and disperse the impact and / or compressive force applied to the screen. The elastic component can effectively absorb the impact force on the screen due to drops, preventing the screen from developing bright spots and black spots due to strong collisions with the hinge assembly, thus improving the structural reliability of the screen and extending its lifespan. In other words, the screen in this embodiment does not need to sacrifice its thickness; the elastic component located between the screen and the hinge assembly effectively improves the screen's reliability during drops. Simultaneously, the overall thickness of the screen is relatively thin, effectively reducing the rebound force when the electronic device is bent, thus improving the user's opening and closing experience.

[0037] In one possible implementation, the first housing includes a first mounting slot. The second housing includes a second mounting slot. When the electronic device is in the open state, the first and second mounting slots form a receiving space. At least a portion of the hinge assembly and at least a portion of the elastic component are located within the receiving space. This allows at least a portion of the elastic component to be located within the receiving space. On one hand, the elastic component can utilize the thickness of the housing, ensuring drop resistance of the screen without increasing the overall thickness of the electronic device, thus facilitating a thinner design. On the other hand, there is no height difference between the elastic component and the first and second adhesive backings of the housing, providing a relatively flat support environment for the screen, improving display quality and enhancing the user experience.

[0038] Secondly, 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 and third portions. 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 smaller 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 an open state.

[0039] Understandably, compared to sequentially stacking and fixing the elastic component and screen onto the hinge assembly of the electronic device, this embodiment first assembles the elastic component and screen together to form a screen assembly, and then fixes the entire screen assembly onto the hinge assembly. This provides a relatively flat supporting environment for the screen during the assembly of the elastic component, making it easier to assemble the elastic component onto the screen. It also helps reduce air bubbles in the adhesive between the elastic component and the screen, thereby effectively improving the connection stability between them. Furthermore, it effectively avoids the problem of delamination and separation of the elastic component and screen at air bubbles due to repeated opening and closing of the electronic device, thus improving the overall structural stability of the electronic device and extending its service life.

[0040] In one possible implementation, the width of the elastic element in the first direction is greater than or equal to the width of the bent portion in the first direction. This elastic element enhances the screen's rigidity, effectively preventing the screen from warping when the electronic device is in the open state, thus improving the overall structural strength of the screen and extending its lifespan.

[0041] 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 support member is made of a rigid material. The width of the support member in a first direction is less than or equal to the width of the elastic member in the first direction. This provides a relatively flat support environment for the screen during the assembly of the support member, making it easier to assemble the support member onto the screen. It also helps reduce air bubbles in the adhesive between the support member and the elastic member, thereby effectively improving the connection stability between them. Furthermore, it effectively avoids the problem of delamination and separation of the support member and the elastic member at air bubbles due to repeated opening and closing of the electronic device, thus improving the overall structural stability of the electronic device and extending its service life.

[0042] In one possible implementation, the thickness of the support component is less than or equal to the thickness of the elastic component. This thinner support component effectively reduces the rebound force when bent, resulting in smoother opening and closing of the electronic device and improved user experience.

[0074] The embodiments of this application are described below with reference to the accompanying drawings.

[0075] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. 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. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. "Rotary connection" refers to a connection where the components can rotate relative to each other after connection. "Sliding connection" refers to a connection where the components can slide relative to each other after connection. The directional terms mentioned in the embodiments of this application, such as "up," "down," "left," "right," "inner," and "outer," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. "Multiple" means at least two.

[0076] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of that feature.

[0077] In the embodiments of this application, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0078] References to "one embodiment" or "some embodiments" as used in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of 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 "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0079] It is understood that the specific embodiments described herein are merely for explaining the relevant invention and not for limiting the invention. It should also be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0080] Figure 1 This is a schematic diagram of the electronic device 1000 provided in the embodiments of this application when it is in the open state. Figure 2 yes Figure 1 The diagram shows the structure of the electronic device 1000 when it is in the closed state.

[0081] like Figure 1 and Figure 2 As shown, the electronic device 1000 may include a housing 200 and a screen 300. The screen 300 may be mounted on the housing 200. The housing 200 may be positioned as follows: Figure 1 The open state shown, and as shown Figure 2The housing device 200 can also be in an intermediate state between an open state and a closed state, as shown in the closed state diagram. The housing device 200 can also be in an intermediate state between an open state and a closed state. The screen 300 can move together with the housing device 200. The housing device 200 can drive the screen 300 to unfold or fold, so that the electronic device 1000 can 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 can be located inside the screen 300. In other words, the electronic device 1000 can be an outward-folding electronic device 1000. For ease of understanding, the direction with the same light emission direction as the screen 300 is defined as "up," and the direction opposite to the light emission direction of the screen 300 is defined as "down." In some embodiments, the electronic device 1000 can also be an inward-folding electronic device.

[0082] In this embodiment, when the electronic device 1000 is in the open state, the screen 300 can be unfolded. At this time, the screen 300 can display in full screen, and the electronic device 1000 has a large display area, which is beneficial 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 easy for users to carry and store.

[0083] For example, screen 300 may integrate display and touch sensing functions. The display function of screen 300 is used to display images, videos, etc., and the touch sensing function of screen 300 is used to sense user touch actions to achieve human-computer interaction. For example, screen 300 includes a flexible display screen that can be bent. The flexible display screen may be a liquid crystal display (LCD), an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a flex 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.

[0084] For example, the electronic device 1000 may also include multiple components (not shown in the figure), which are installed inside the housing device 200. These components may include, for example, a processor, 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, buttons, a motor, an indicator, and a subscriber identification module (SIM) card interface, etc.

[0085] It should be understood that Figure 1 and Figure 2 The electronic device 1000 is shown only schematically, and the actual shape, size, and construction of these components are not subject to change. Figure 1 and Figure 2 Limitation. In other embodiments, when the electronic device 1000 is a device of other types, the electronic device 1000 may not include the screen 300.

[0086] In this embodiment, the electronic device 1000 is described as having a two-fold structure, meaning that the electronic device 1000 includes two flat plate parts and a bent portion connecting the two flat plate parts. The two flat plate parts can rotate towards each other to overlap (corresponding to the closed state mentioned earlier), giving the electronic device 1000 a two-layer shape; the two flat plate parts can also rotate away from each other to flatten (corresponding to the open state mentioned earlier). In other embodiments, the electronic device 1000 can also have a three-fold or more-fold structure, meaning that the electronic device 1000 includes three or more flat plate parts, with adjacent flat plate parts connected by a bent portion, and adjacent flat plate parts can rotate relative to each other to overlap or away from each other to flatten. When the electronic device 1000 has a three-fold or more-fold structure, the structure of the electronic device 1000 can be adapted by referring to the description of the two-fold structure in this embodiment, and will not be repeated here.

[0087] Figure 3 yes Figure 1 A partially exploded view of the electronic device 1000 in some embodiments. Figure 4 yes Figure 1 A partial cross-sectional view of one embodiment of the electronic device 1000 shown, cut along point AA. Figure 5 yes Figure 2 A partial cross-sectional view of one embodiment of the electronic device 1000 shown, cut along BB.

[0088] like Figures 3 to 5As shown, the housing device 200 may include a pivot assembly 210, a first housing 220, and a second housing 230. The pivot assembly 210 connects the first housing 220 and the second housing 230. The pivot assembly 210 can move to allow the first housing 220 and the second housing 230 to be relatively unfolded to an open state or relatively folded to a closed state. It should be understood that both the first housing 220 and the second housing 230 are housing components used to mount and fix other components of the electronic device 1000, and have diverse structures. The pivot assembly 210 is used to realize the relative movement between the first housing 220 and the second housing 230, and also has diverse structures. The embodiments of this application do not strictly limit the specific structures of the first housing 220, the second housing 230, and the pivot assembly 210. The accompanying drawings of this application only illustrate the general structure of the first housing 220, the second housing 230, and the pivot assembly 210 in one embodiment.

[0089] For example, the pivot 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. Both the first connecting portion 211 and the second connecting portion 212 can be connected to the main shaft portion 213. Both the first connecting portion 211 and the second connecting portion 212 can move relative to the main shaft portion 213 to achieve relative unfolding and relative folding actions.

[0090] For example, the upper surface of the spindle portion 213 can be generally arc-shaped. The portion of the upper surface of the spindle portion 213 at the apex of the arc can be flat, forming a flat surface 213a of the spindle portion 213. That is, the flat surface 213a can be positioned close to the screen 300. In this case, the upper surface of the spindle portion 213 can be an incomplete arc shape. The flat surface 213a can coincide with the central axis of the spindle portion 213 in the thickness direction of the pivot assembly 210, meaning the flat surface 213a can be located at the middle position of the spindle portion 213. In some embodiments, both the first connecting portion 211 and the second connecting portion 212 can include a connector for realizing movement and a support plate for providing support. The support plate can be located above the connector.

[0091] Exemplarily, the first housing 220 may be provided with a first mounting groove 221. The second housing 230 may be provided with a second mounting groove 231. The first connecting portion 211 of the pivot assembly 210 may be located within the first mounting groove 221 and connected to the first housing 220. The second connecting portion 212 of the pivot assembly 210 may also be located within the second mounting groove 231 and connected to the second housing 230. In this embodiment, the first connecting portion 211 may be fixedly connected to the first housing 220. The second connecting portion 212 may be fixedly connected to the second housing 230. In some embodiments, the first connecting portion 211 may also be movably connected (e.g., rotatably connected and / or slidably connected) to the first housing 220. Alternatively, the first connecting portion 211 may also be indirectly fixedly connected to the first housing 220 through other components.

[0092] Exemplarily, the housing device 200 may further include a first adhesive 240 and a second adhesive 250. The first adhesive 240 can be fixedly connected to the upper surface of the first housing 220. The second adhesive 250 can be fixedly connected to the upper surface of the second housing 230. Both the first adhesive 240 and the second adhesive 250 can be used to fix the screen 300.

[0093] When the electronic device 1000 is in the open state, the first housing 220 and the second housing 230 can be relatively flattened. The first connecting portion 211 and the second connecting portion 212 of the hinge assembly 210 can be relatively flattened. The flat surface 213a of the hinge assembly 210 can be parallel to the screen 300. At this time, 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. At this time, 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. A portion of the main shaft portion 213 can be located within the first mounting groove 221. Another portion of the spindle 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 opposite sides of the spindle portion 213 and are relatively flattened. In some embodiments, the first connecting portion 211 may further include a first support plate for providing support and a first connector for connecting 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 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 support plate and the second support plate is less than or equal to the distance between the first connector and the second connector, 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 support plate and the second support plate is greater than the distance between the first connector and the second connector, 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.

[0094] When the electronic device 1000 is in the 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 pivot assembly 210 can be folded relative to each other and are 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. Exemplarily, 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 the closed state, there may also be a gap between the lower surfaces of the first housing 220 and the lower surfaces of the second housing 230.

[0095] 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 housing 220 points towards the second housing 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. Figure 4 The first direction is also indicated by an arrow. Unless otherwise specified in the following text of this application, the width direction of a component is... Figure 4 The first direction is indicated. The width of a 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.

[0096] Please refer to it again. Figure 3 The electronic device 1000 may further include an elastic component 100. The elastic component 100 can be fixed between the screen 300 and the hinge assembly 210. When the electronic device 1000 is in the open state, the screen 300, the elastic component 100, and the hinge assembly 210 can be stacked sequentially. The elastic component 100 can be used to improve the reliability of the screen 300 when the electronic device 1000 is dropped. The elastic component 100 may include an elastic part and a supporting part. The elastic part and the supporting part can be stacked along the thickness direction of the electronic device 1000. The material of the elastic part may be different from the material of the supporting part. The elastic part may include at least one elastic element. The supporting part may include at least one supporting element. When the elastic part includes only one elastic element and the supporting part also includes only one supporting element, the elastic element and the supporting element can be stacked along the thickness direction of the electronic device 1000. When the elastic part includes multiple elastic elements and the supporting part includes multiple supporting elements, the multiple elastic elements and the multiple supporting elements can be alternately stacked sequentially.

[0097] When the electronic device 1000 is dropped and the screen 300 is impacted, the supporting portion of the elastic component 100 can effectively absorb the impact force and / or compressive force exerted on the screen 300 by the hinge assembly 210, reducing the impact force on the screen 300 and providing good rigid support for the screen 300. The elastic portion of the elastic component 100 can play a good elastic role in resisting the impact force and / or compressive force applied to the screen 300, and at the same time, the elastic portion can also absorb and disperse the impact force and / or compressive force exerted on the screen 300. In other words, the elastic component 100 in this embodiment includes both an elastic portion and a supporting portion. The elastic portion and the supporting portion can respectively provide good rigid protection and elastic protection for the screen 300. The entire elastic component 100 has strong impact resistance and compression resistance, which enables the elastic component 100 to better protect the screen 300, improve the drop reliability of the screen 300, and help extend the service life of the screen 300.

[0098] In this embodiment, the elastic component 100 may include a first support member 10, a first elastic member 20, a lubricant 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 support portion of the elastic component 100 may include two support members, and 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 lubricant 30, the second support member 50, the second adhesive 60, the second elastic member 70, and the third adhesive 80 may be stacked sequentially along the direction from the pivot assembly 210 toward the screen 300.

[0099] When the electronic device 1000 is in the open state, all components of the elastic component 100 can be in the open state accordingly. The width of the elastic component 100 can be less than or equal to the first width L1 (e.g., ...). Figure 4 (As shown). When the electronic device 1000 is in the closed state, each component of the elastic assembly 100 can be in the closed state accordingly. In some other embodiments, the elastic assembly 100 may not include the second elastic element 70, the second support element 50, the second adhesive 60, the lubricant 30, and the third adhesive 80.

[0100] The structure and relative positional relationships of the various components in the elastic component 100 will be described in detail below with reference to the relevant accompanying drawings.

[0101] Figure 6 yes Figure 3 A schematic diagram of the structure of the first support member 10 of the elastic component 100 shown.

[0102] like Figure 6 As shown, the first support member 10 can be made of a rigid material with 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 external force. Of course, while meeting the support performance requirements, the first support member 10 can also be a metal sheet or non-metal sheet such as an aluminum sheet, stainless steel sheet, titanium alloy sheet, aluminum alloy sheet, or copper alloy sheet; this application does not impose strict limitations on this.

[0103] Exemplarily, the first support member 10 may be generally 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. In this case, the first portion 11, the second portion 12, and the third portion 13 may be arranged sequentially along the width direction of the first support member 10. It should be understood that... Figure 6 and Figure 7The first part 11, the second part 12, and the third part 13 of the first support member 10 are schematically divided by dashed lines. Although the first support member 10 is described in three parts in this embodiment, it does not affect the fact that the first support member 10 can be a one-piece molded structure, that is, the first part 11, the second part 12, and the third part 13 of the first support member 10 can be integrally molded.

[0104] Figure 7 yes Figure 3 A schematic diagram of the assembly structure of the first support member 10 and the first elastic member 20 of the elastic component 100 shown.

[0105] like Figure 7 As shown, the material of the first elastic element 20 can be an elastic material or a non-Newtonian fluid material. The elastic material can be a thermoplastic polyurethane elastomer (TPU) or other materials possessing a certain degree of elasticity. The elastic modulus of the elastic material can be much smaller than that of the rigid material. For example, the elastic modulus of thermoplastic polyurethane elastomer can be between 0.01 GPa and 1 GPa. The elastic modulus of stainless steel can be around 200 GPa. The non-Newtonian fluid material refers to a material where the shear stress and shear strain rate have a non-linear relationship. The hardness of the elastic material can be much greater than that of the non-Newtonian fluid.

[0106] 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, etc. In this way, the thickness of the first support member 10 is relatively thin, which helps to reduce the rebound force when the electronic device 1000 is bent.

[0107] 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 a second direction. The second direction refers to the thickness direction of the electronic device 1000 when the electronic device 1000 is in the open state. It should be understood that the term "second direction" as used below applies to the above definition.

[0108] For example, the shape of the first elastic member 20 can be approximately the same as the shape of the first support member 10. The width of the first elastic member 20 can be the same as the width 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 means of bonding or the like. Specifically, when the material of the first elastic member 20 is thermoplastic polyurethane elastomer, a layer of adhesive can be applied to 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 this 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.

[0109] Figure 8 yes Figure 3 An exploded view of the first support member 10, the first elastic member 20, and the lubricating member 30 of the elastic component 100 shown. Figure 9a yes Figure 1 A partial cross-sectional view of one embodiment of the electronic device 1000 shown, cut along point AA. Figure 9b yes Figure 9a The diagram shows the structure after it has been flipped upside down.

[0110] like Figures 8 to 9a As shown, the lubricant 30 can be Mylar, such as insulating Mylar. The surface of the lubricant 30 is relatively smooth, with low surface roughness. The lubricant 30 may include a main body 31, a first bent portion 32, and a second bent portion 33. The main body 31 can connect the first bent portion 32 and the second bent portion 33. It should be understood that although this embodiment describes the lubricant 30 as three parts, it does not affect the fact that the lubricant 30 is a one-piece molded structure, that is, the main body 31, the first bent portion 32, and the second bent portion 33 of the lubricant 30 can be integrally molded. It should be noted that... Figure 9a and Figure 9b The main body 31, the first bend 32, and the second bend 33 of the lubricating component 30 are schematically divided by dashed lines.

[0111] For example, the main body 31 may include a first surface 31a and a second surface 31b disposed opposite to 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 reference). Figure 3The first bending portion 32 may include a first connecting portion 321 and a first extension portion 322. The first extension portion 322 may be located on the side of the second surface 31b of the main body portion 31 away from the first surface 31a. The first extension portion 322 may be spaced apart from the main body portion 31 in a second direction. The first extension portion 322 may include a third surface 322a and a fourth surface 322b disposed opposite to each other. The third surface 322a is the surface of the first extension portion 322 facing the main body portion 31. The fourth surface 322b is the surface of the first extension portion 322 facing away from the main body portion 31, that is, the fourth surface 322b is the surface of the first extension portion 322 facing the rotating shaft 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 may connect the main body portion 31 and the first extension portion 322. At this time, the main body 31, the first connecting part 321, and the first extension part 322 can collectively enclose the first semi-enclosed accommodating space 32a, that is, the main body 31 and the first bending part 32 can jointly enclose the first semi-enclosed accommodating space 32a. It should be noted that... Figure 9a and Figure 9b The first connecting part 321 and the first extension part 322 of the first bending part 32 are schematically divided by dashed lines.

[0112] Exemplarily, the second bending portion 33 may include a second connecting portion 331 and a second extension portion 332. The second extension portion 332 may be located on the side of the second surface 31b of the main body portion 31 away from the first surface 31a. The second extension portion 332 may be spaced apart from the main body portion 31 in a second direction. The second extension portion 332 may include a fifth surface 332a and a sixth surface 332b disposed opposite to each other. Wherein, the fifth surface 332a is the surface of the second extension portion 332 facing the main body portion 31. The sixth surface 332b is the surface of the second extension portion 332 facing away from the main body portion 31, that is, the sixth surface 332b is the surface of the second extension portion 332 facing the rotating shaft assembly 210. The end of the second extension portion 332 away from the second connecting portion 331 is the second end 332c. The second connecting portion 331 may connect the main body portion 31 and the second extension portion 332. At this time, the main body 31, the second connecting part 331, and the second extension 332 can jointly enclose the second semi-enclosed accommodating space 33a, that is, the main body 31 and the second bending part 33 can jointly enclose the second semi-enclosed accommodating space 33a. At this time, the second extension 332 and the first extension 322 can be located on the same side of the main body 31. The second extension 332 and the first extension 322 can be spaced apart along the width direction of the lubricating member 30. It should be noted that... Figure 9a and Figure 9b The second connecting part 331 and the second extension part 332 of the second bending part 33 are schematically divided by dashed lines.

[0113] like Figures 8 to 9bAs shown, 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 means of bonding or the like. The shape of the main body 31 of the lubricating member 30 can be approximately the same as the shape of the first elastic member 20. The width of the main body 31 of the lubricating member 30 can be the same as the width of the first elastic member 20.

[0114] For example, the first bent portion 32 of the lubricant 30 can be bent relative to the main body 31 to contact 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 opposite to 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 means of adhesion or the like. The first end 322c of the first extension 322 can face the second extension 332. The first connecting portion 321 can be provided on the 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 lubricant 30, the first elastic member 20, the first portion 11 of the first support member 10, and the first extension 322 of the lubricant 30 can be stacked sequentially 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.

[0115] For example, the second bent portion 33 of the lubricant 30 can be bent relative to the main body 31 to contact 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 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 means of adhesion or the like. The second end 332c of the second extension 332 can face the first extension 322. The second connecting portion 331 can be provided on the 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 lubricant 30, the first elastic member 20, the third portion 13 of the first support member 10, and the second extension 332 of the lubricant 30 can be stacked sequentially 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.

[0116] Understandably, compared to having two lubricants respectively on the surface of the first support member facing away from the first elastic member and 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 lubricant 30 in this embodiment can have a main body 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 bending towards the first portion 11 of the first support member 10 and a second bent portion 33 bending towards the third portion 13 of the first support member 10. In this way, the lubricant 30 can not only simultaneously cover the surface of the first elastic member 20, part of the surface of the first portion 11 of the first support member 10, and part of the surface of the third portion 13 of the first support member 10, but also wrap around the outer edges of the first elastic member 20 and the first support member 10, thus protecting the outer edges of the first elastic member 20 and the first support member 10 and preventing them from scratching other components and causing abnormal noise. At the same time, the first support member 10 is relatively thin, and its outer edge is relatively sharp. By providing a lubricant 30 to wrap around 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 is possible to effectively prevent the edge of the first support member 10 from scratching the assembly personnel during the installation of the first support member 10 with other components, which is beneficial to improving the safety of the assembly process.

[0117] Figure 10 yes Figure 1 A partial structural schematic diagram of the electronic device 1000 shown. Figure 11a yes Figure 1 A partial cross-sectional view of one embodiment of the electronic device 1000 shown, cut along point AA. Figure 11b yes Figure 2 A partial cross-sectional view of one embodiment of the electronic device 1000 shown, cut along BB.

[0118] like Figures 10 to 11b As shown, the second part 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 means of welding, bonding, or other methods. At this time, the second part 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.

[0119] When the electronic device 1000 is in the open state, the width of the first support member 10 is the 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 part 11 of the first support member 10 and the first extension 322 of the first bent part 32 of the lubricant 30 can overlap with the first connecting part 211 of the pivot assembly 210, and the third part 13 of the first support member 10 and the second extension 332 of the second bent part 33 of the lubricant 30 can overlap with the second connecting part 212 of the pivot assembly 210. When the electronic device 1000 is in the closed state, the first part 11 of the first support member 10 and the first extension 322 of the first bent part 32 of the lubricant 30 can overlap with the first connecting part 211 of the pivot assembly 210, and the third part 13 of the first support member 10 and the second extension 332 of the second bent part 33 of the lubricant 30 can overlap with the second connecting part 212 of the pivot assembly 210. Specifically, the first end 322c of the first extension 322 of the lubricant 30 can be located within the gap between the main shaft portion 213 and the first connecting portion 211 of the shaft assembly 210. Similarly, the second end 332c of the second extension 332 of the lubricant 30 can be located within the gap between the main shaft portion 213 and the first connecting portion 211 of the shaft assembly 210. This allows the width of the first support member 10 (i.e., the third width L3) to be smaller than the width of the shaft assembly 210 (i.e., the first width L1). A narrower width of the first support member 10 helps reduce the rebound force when bending, thus improving the opening and closing experience of the electronic device 1000. Meanwhile, 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). This allows the first support member 10 to cover part of the gap between the main shaft portion 213 and the first connecting portion 211 and part of 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, regardless of whether the electronic device 1000 is in the open or closed state. This prevents the outer edge of the first support member 10 from interfering with the hinge assembly 210 due to its location at the gap, thus avoiding affecting the opening and closing of the electronic device 1000. Furthermore, the first support member 10 can overlap the first connecting portion 211 and the second connecting portion 212, which is beneficial for providing a relatively flat support environment for the subsequent fixed assembly of components. In some embodiments, when the electronic device 1000 is in a closed state, the first end 322c of the first extension 322 of the lubricant 30 may also overlap the first connecting portion 211 or the spindle portion 213.

[0120] For example, the first portion 11 of the first support member 10 can overlap the first connecting portion 211 of the shaft assembly 210 via the first bend 32 of the lubricant 30, and can move relative to the first connecting portion 211. The third portion 13 of the first support member 10 can overlap the second connecting portion 212 of the shaft assembly 210 via the second bend 33 of the lubricant 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 bent part 32 of the lubricant 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 bent part 33 of the lubricant 30 relative to the second connecting part 212 of the rotating shaft assembly 210. Since the coefficient of friction between the lubricant 30 and the rotating shaft assembly 210 is smaller than that 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 and causing scratches when it moves, which helps to reduce the abnormal noise when the electronic device 1000 is bent.

[0121] In this embodiment, the second portion 12 of the first support member 10 can be fixedly connected to the spindle portion 213 by welding. For example, a welding torch can weld the first support member 10 to the flat surface 213a of the shaft assembly 210 at the surface of the first support member 10 exposed by one or more of the dispensing holes 20a. At this time, the weld point 10a between the first support member 10 and the shaft assembly 210 can be located on the flat surface 213a of the spindle portion 213. The weld point 10a can be exposed relative to the dispensing hole 20a. The weld point 10a can be spaced apart from the second through hole 14 of the first support member 10. It should be understood that... Figure 10 and Figure 11a The location of solder joint 10a is indicated by dashed circles.

[0122] Understandably, compared to the first support member 10 being fixedly connected to the main shaft portion 213 of the hinge assembly 210 by adhesive bonding, the first support member 10 may detach from the hinge assembly 210 during the opening and closing of the electronic device 1000 or under some extreme conditions, leading to problems such as screen 300 arching and wiring breakage. In this embodiment, the first support member 10 can be fixedly connected to the main shaft portion 213 of the hinge assembly 210 by welding, allowing the first support member 10 to be more stably fixed to the hinge assembly 210. Thus, even if the electronic device 1000 is opened and closed repeatedly, or under some extreme conditions, the first support member 10 can maintain a fixed connection with the hinge assembly 210, effectively preventing screen 300 arching and wiring breakage due to the first support member 10 detaching. This improves the overall structural stability of the electronic device 1000 and extends its service life.

[0123] Secondly, compared to sequentially stacking and fixing the first support member 10, the first elastic member 20, and the lubricating member 30 onto the rotating shaft assembly 210, this embodiment first assembles the first support member 10, the first elastic member 20, and the lubricating member 30 together to form a whole, and then fixes the whole together onto the rotating shaft assembly 210. In this way, on the one hand, it can effectively prevent 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 lubricating member 30, which would cause some components to stick together and affect the opening and closing experience of the electronic device 1000; on the other hand, since the first support member 10 and the first elastic member 20 are both flat sheet structures, the first elastic member 20 and the lubricating member 30 can be assembled in a relatively flat supporting environment during the bonding and fixing process. The first support member 10, the first elastic member 20 and the lubricating member 30 are easier to assemble, and it also helps to reduce air 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. It can also effectively prevent the first elastic member 20 or the lubricating member 30 from delaminating and separating at the air bubbles due to repeated opening and closing of the electronic device 1000, which is conducive to improving the overall structural stability of the electronic device 1000 and extending the service life of the electronic device 1000.

[0124] Figure 12 yes Figure 1 A partial structural schematic diagram of the electronic device 1000 shown. Figure 13 yes Figure 1 A partial cross-sectional view of one embodiment of the electronic device 1000 shown, cut along point AA.

[0125] like Figure 12 and Figure 13 As shown, the first elastic member 20 may have multiple first through holes 21. The multiple first through holes 21 may be spaced apart along the length extension direction of the first elastic member 20. The shapes and sizes of the multiple first through holes 21 may not be identical. The second part 12 of the first support member 10 may have multiple second through holes 14. The multiple second through holes 14 may be spaced apart along the length extension direction of the first support member 10. The shapes and sizes of the multiple second through holes 14 may not be identical. The second through holes 14 may expose a portion of 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 multiple first through holes 21 may expose the multiple second through holes 14 in a one-to-one correspondence and connect with the multiple second through holes 14. In this case, the first through holes 21 may also expose a portion of the flat surface 213a of the main shaft portion 213.

[0126] For example, the opening size of the second through hole 14 in each group of second through holes 14 and first through holes 21 may not be greater than the opening size of the first through hole 21. In this case, the first through hole 21 and the second through hole 14 may at least partially overlap in the thickness direction of the electronic device 1000. In this embodiment, the opening size of the second through hole 14 in each group of second through holes 14 and first through holes 21 may be smaller than the opening size of the first through hole 21. In this case, the plurality of first through holes 21 may also expose a portion of the upper surface of the first support member 10 around the plurality of second through holes 14, for example, exposing a portion of the upper surface of the second part 12 of the first support member 10. In other embodiments, the opening size of the second through hole 14 in each group of second through holes 14 and first through holes 21 may be equal to the opening size of the first through hole 21. In this case, the plurality of first through holes 21 may only expose a portion of the flat surface 213a of the spindle part 213.

[0127] 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 length 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 the third through-holes 34 may be the same as the number of the first through-holes 21. The plurality of third through-holes 34 may expose the plurality of first through-holes 21 one by one and communicate with 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 with the plurality of first through-holes 21 one by one. Among them, the shapes and sizes 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 as the opening size of the first through-holes 21. At this time, the plurality of third through-holes 34 may also expose the plurality of second through-holes 14 and the upper surface of a part of the first support member 10 exposed by the plurality of first through-holes 21 one by one. That is, the plurality of dispensing holes 20a may expose the plurality of second through-holes 14 and the upper surface of a part of the first support member 10 exposed by the plurality of first through-holes 21 one by one. It should be noted that Figures 6 to 10 The first through-hole 21, the second through-hole 14, and the third through-hole 34 are also schematically shown.

[0128] As Figure 12 and Figure 13 shown, the first adhesive 40 may be in a块状 shape. The number of the first adhesives 40 may be multiple. The thicknesses of the multiple first adhesives 40 may be the same. The number of the first adhesives 40 may be the same as the number of the dispensing holes 20a. The multiple first adhesives 40 may be located in the multiple dispensing holes 20a and the multiple second through-holes 14 one by one. At this time, each first adhesive 40 may be substantially in an inverted "convex" shape. A part of the first adhesive 40 may 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 part of the first adhesive 40 may be located in the dispensing hole 20a and connect the part of the upper surface of the first support member 10 exposed in the dispensing hole 20a. Exemplarily, the first adhesive 40 may be a hot-melt adhesive. The hot-melt adhesive may be filled in each dispensing hole 20a and may flow into the multiple second through-holes 14 one by one before it is cured. After the hot-melt adhesive is cured, the first adhesive 40 in an inverted "convex" shape may be formed.

[0129] It should be noted that the Chinese character "块状" in the original text seems to be incorrect. I translated it as "块状 shape" for the sake of understanding. If it is a specific term, it may need to be adjusted according to the correct content.In some embodiments, the dimensions 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 position may be slightly larger than the length of the other second through holes 14. The spacing 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. Thus, by changing the length of each second through hole 14 and the spacing between two adjacent second through holes 14, when the first support member 10 is subsequently fixedly connected to the rotating shaft assembly 210, each second through hole 14 can avoid the uneven structure in the main shaft portion 213 of the rotating shaft assembly 210, thereby facilitating the installation and fixing of other components (please refer to [reference needed]). Figure 4 ).

[0130] In other embodiments, the first elastic member 20 may have only one first through hole 21, and the lubricating member 30 may have 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 the upper surface of the first support member 10 surrounding each second through hole 14. The third through hole 34 may have 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 form an elongated dispensing hole 20a. The number of first adhesives 40 may also be one. In this case, the first adhesive 40 may be elongated, adapted to the shape of the dispensing hole 20a. This elongated first adhesive 40 may simultaneously fill the elongated dispensing hole 20a and multiple second through holes 14.

[0131] In some 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 can be two-to-one, for example, one third through hole 34 can correspond to two first through holes 21. Alternatively, the relationship between the plurality of first through holes 21 and the plurality of third through holes 34 can also be three-to-one, one-to-two, two-to-three, etc. In other words, there are multiple combinations of the plurality of first through holes 21 and the plurality of third through holes 34. This application does not impose specific limitations on this.

[0132] Figure 14 yes Figure 1 A partial structural schematic diagram of the electronic device 1000 shown. Figure 15a yes Figure 1 A partial cross-sectional view of one embodiment of the electronic device 1000 shown, cut along point AA. Figure 15b yes Figure 2 A partial cross-sectional view of one embodiment of the electronic device 1000 shown, cut along BB.

[0133] like Figures 14 to 15b As shown, 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 external force. Of course, while meeting the support performance requirements, the second support member 50 can also be a metal sheet or non-metal sheet such as an aluminum sheet or stainless steel sheet. This application does not impose strict limitations on this. The length of the second support member 50 can be slightly shorter than the length of the rotating shaft assembly 210.

[0134] For example, 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. At this time, the second support member 50 can be fixedly connected to the flat surface 213a of the main shaft portion 213 of the rotating shaft assembly 210 through the first adhesive 40. Except for the part of the second support member 50 that is fixedly connected to the first adhesive 40, it can overlap the lubricating member 30 and can move 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. For example, the fourth width L4 can also be less than or equal to the second width L2. At this time, the second support member 50 and the first connecting portion 211 of the rotating shaft 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 rotating shaft 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 pivot assembly 210 do not overlap in the thickness direction of the electronic device 1000. Similarly, the second connecting portion 212 of the second support member 50 and the pivot assembly 210 also does not overlap in the thickness direction of the electronic device 1000. This results in a narrower width for the second support member 50, effectively reducing the rebound force when the second support member 50 bends, making the opening and closing of the electronic device 1000 smoother and improving the user experience.

[0135] It is understood that, in this embodiment, by providing a first through hole 21 on the first elastic member 20, a second through hole 14 on the first support member 10, and a third through hole 34 on the lubricating member 30, the first adhesive 40 can be located within the aforementioned 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 beneficial 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 member 100, which is beneficial to achieving a thinner design of the electronic device 1000. Meanwhile, the thickness of the first adhesive 40 can be controlled by the through holes (i.e., the second through hole 14, the first through hole 21, and the third through hole 34 in this embodiment) on the first support member 10, the first elastic member 20, and the lubricating member 30. This can avoid the problem that the first adhesive 40 is too thin and cannot guarantee the connection stability of the second support member 50, and also avoid the problem that the screen 300 is uneven due to the first adhesive 40 being too thick.

[0136] Secondly, in this embodiment, the opening of the second through hole 14 of the first support member 10 may not be 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 the same size as 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. Thus, 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 exposes part of the flat surface 213a of the rotating shaft assembly 210. This allows the first adhesive 40 to achieve a fixed connection between the second support member 50 and the rotating shaft assembly 210 without overflowing from the second through hole 14 onto other parts of the rotating shaft assembly 210. This effectively avoids the problem of other parts sticking together 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 fixed to the shaft assembly 210 through the first adhesive 40, and can also be fixed to the upper surface of the first support member 10 through the first adhesive 40. This increases the fixing area between the first adhesive 40 and the first support member 10, thereby effectively improving the connection stability between the second support member 50 and the shaft assembly 210, as well as 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.

[0137] In other embodiments, the first support member 10 may not have 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 can be fixedly connected to the portion of the first support member 10 exposed by the first through hole 21 using the first adhesive 40.

[0138] Figure 16a yes Figure 3 The diagram shows the exploded structure of the screen 300, the second elastic element 70, and the third adhesive 80 of the electronic device 1000 after being flipped up and down. Figure 16b yes Figure 16a The diagram shows the assembly structure of the screen 300, the second elastic element 70, and the third adhesive 80.

[0139] like Figure 16a and Figure 16bAs shown, the screen 300 may include a flexible display screen 301 and a support plate 302 for supporting the flexible display screen 301. The support plate 302 may be located on the non-display side of the flexible display screen 301 and is fixedly connected to the flexible display screen 301. Figure 3 The diagram also illustrates the flexible display screen 301 and the support plate 302 of the screen 300. The flexible display screen 301 can be bent, and the support plate 302 can be bent and has a certain structural strength, so that the screen 300 can not only realize unfolding and folding actions, but also has a certain structural strength, thus having high structural reliability.

[0140] For example, 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 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... Figure 16a and Figure 16b The screen 300 is schematically divided into three parts: the first part 310, the second part 320, and the third part 330, using dashed lines. For ease of understanding, the volume of the second part 320, indicated by the dashed lines, is slightly larger than the actual volume of the second part 320.

[0141] For example, the portion of the support plate 302 located in the second part 320 may have multiple slotted holes 302a. The multiple slotted holes 302a may extend in the same direction. The length extension direction of the multiple slotted holes 302a may be the same as the length extension direction of the pivot assembly 210. In this way, the multiple slotted holes 302a can effectively reduce the stiffness of the portion of the support plate 302 located in the second part 320. When the electronic device 1000 is bent, the portion of the support plate 302 located in the second part 320 can bend more easily, which is beneficial to improving the opening and closing experience of the electronic device 1000. In some embodiments, the portion of the support plate 302 located in the first part 310 near the second part 320 may also have multiple slotted holes 302a. The portion of the support plate 302 located in the third part 330 near the second part 320 may also have multiple slotted holes 302a. Thus, the second part 320 of the screen 300 can also be provided with strip-shaped holes 302a on both sides, which can better reduce the rebound force when the second part 320 is bent, and improve the opening and closing experience of the electronic device 1000. In some embodiments, in order to reduce the rebound force when the second part 320 is bent and improve the opening and closing experience of the electronic device 1000, the second part 320 can also be provided with strip-shaped grooves on both sides, and the length extension direction of the strip-shaped grooves can be the same as the length extension direction of the hinge assembly 210.

[0142] like Figure 16a and Figure 16bAs shown, the material of the second elastic element 70 can be an elastic material or a non-Newtonian fluid material. The thickness of the second elastic element 70 can be greater than or equal to that of the second support element 50 (see [reference]). Figure 15a The thickness of the second elastic element 70 can be in the range of 0.02 mm to 0.15 mm. For example, the thickness of the first elastic element 20 can be 0.03 mm, 0.042 mm, 0.075 mm, 0.1 mm, or 0.12 mm, etc.

[0143] 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 the third adhesive 80. In this case, the second elastic member 70 and the screen 300 can be 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 approximately 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 holes 302a of the support plate 302 in the thickness direction of the electronic device 1000, that is, the third adhesive 80 can cover the multiple strip holes 302a of the support 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 support plate 302 with strip holes 302a (that is, the portion of the support plate 302 located in the second part 320 in this embodiment), thereby effectively preventing the electronic device 1000 from falling when in the open state, causing the portion of the support plate 302 with strip holes 302a to arch, and causing the second part 320 of the screen 300 to arch, which is beneficial to improving the overall structural strength of the screen 300 and extending the service life of the screen 300.

[0144] Figure 17 yes Figure 1 A partial cross-sectional view of one embodiment of the electronic device 1000 shown, cut along point AA.

[0145] like Figure 17As shown, the second adhesive 60 can be generally elongated. 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 a hot melt adhesive or other adhesive with a certain degree of deformation capability. 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 pivot assembly 210.

[0146] The width of the second adhesive 60 can be smaller than the width of the second support 50.

[0147] 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, most of the second adhesive 60 can be located directly above the main shaft portion 213 of the pivot assembly 210. The narrower width of the second adhesive 60 can effectively reduce the rebound force when the second adhesive 60 is bent, which is beneficial to improving the opening and closing experience of the electronic device 1000.

[0148] In some embodiments, the width of the second adhesive 60 may be equal to the width of the flat surface 213a of the pivot assembly 210. This equality can be exact or approximately equal; for example, the width of the second adhesive 60 may be slightly greater or slightly smaller than the width of the flat surface 213a.

[0149] Figure 18a yes Figure 1 The diagram shows a partial cross-sectional view of one embodiment of the electronic device 1000 cut along point AA. Figure 18b yes Figure 1 This is a partial cross-sectional view of one embodiment of the electronic device 1000, cut along point AA. Wherein, Figure 18b relatively Figure 18a The 300-degree angle of the screen is hidden.

[0150] like Figures 17 to 18b As shown, the first portion 310 of the screen 300 can be located above the first housing 220 and is fixedly connected to the first adhesive backing 240. The third portion 330 of the screen 300 can be located above the second housing 230 and is fixedly connected to the second adhesive backing 250. Wherein, Figure 4 The first adhesive 240 and the second adhesive 250 are also shown from another perspective. At this time, the flexible display screen 301 can be located on the side of the support plate 302 facing away from the pivot 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 member 100, and the pivot assembly 210 can be stacked along the thickness direction of the electronic device 1000.

[0151] 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 the open state, the first portion 101, the third portion 103, and the second portion 102 may be arranged sequentially along a first direction. The first portion 101 of the elastic component 100 may overlap with the first connecting portion 211 of the pivot assembly 210. The second portion 102 of the elastic component 100 may overlap with the second connecting portion 212 of the pivot assembly 210. The third portion 103 of the elastic component 100 may be fixedly connected to the main shaft portion 213 of the pivot assembly 210. It should be understood that... Figure 18b The first part 101, the second part 102, and the third part 103 of the elastic component 100 are schematically divided by dashed lines.

[0152] Understandably, compared to sequentially stacking and fixing the second elastic element 70, the third adhesive 80, and the screen 300 onto the second adhesive 60, this embodiment first assembles the second elastic element 70, the third adhesive 80, and the screen 300 together to form a screen assembly 400, and then fixes the entire screen assembly 400 together onto the second adhesive 60. This provides a relatively flat supporting environment for the screen 300 during the assembly of the second elastic element 70 and the third adhesive 80, making it easier to assemble the second elastic element 70 and the third adhesive 80 onto the screen 300. It also helps reduce air bubbles in the third adhesive 80, thereby effectively improving the connection stability between the second elastic element 70, the third adhesive 80, and the screen 300. Furthermore, it effectively avoids the problem of delamination and separation of the second elastic element 70 and the third adhesive 80, or the screen 300 and the third adhesive 80, at air bubbles due to 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 element.

[0153] In other embodiments, the second support member 50 and the second adhesive 60 may be assembled together with the screen 300, the second elastic member 70, and the third adhesive 80 to form a screen assembly 400. Then, the entire screen assembly 400 is fixed together with the other components of the electronic device 1000. In other words, the screen assembly 400 in this embodiment may also include at least one support member.

[0154] Please refer to it again. Figure 18a and Figure 18bWhen the electronic device 1000 is in the open state, both the screen 300 and the elastic component 100 can be relatively flattened under the action of the housing device 200. The first support member 10, the first elastic component 20, the second support member 50, and the second elastic component 70 can all be located above the flat surface 213a of the pivot assembly 210, and are arranged sequentially along the direction from the housing device 200 toward the screen 300.

[0155] For example, at least a portion of the resilient component 100 may be located within the first mounting slot 221, i.e., within the receiving space 200a (see [link]). Figure 4 The sum of the thickness of the elastic component 100 and the thickness of the pivot assembly 210 can be equal to the first distance H1. That is, the surface of the elastic component 100 facing away from the pivot assembly 210 (in this embodiment, the surface of the third adhesive 80 facing away from the pivot assembly 210) can be flush with the upper surface of the first adhesive 240. It should be noted that the sum of the thickness of the elastic component 100 and the thickness of the pivot assembly 210 being equal to the first distance H1 can be understood as being completely equal or approximately equal, that is, there can be a certain error between the sum of the thickness of the elastic component 100 and the thickness of the pivot assembly 210 and the first distance H1, for example, the error can be within the range of ±0.1 mm.

[0156] The first elastic member 20 and the second elastic member 70 can together constitute the elastic portion of the elastic component 100. The total thickness of the elastic portion can be in the range of 0.2 mm to 0.4 mm. The first support member 10 and the second support member 50 can together constitute the support portion of the elastic component 100. The total thickness of the support portion can be less than or equal to the total thickness of the elastic portion.

[0157] Figure 19a yes Figure 2 A partial cross-sectional view of one embodiment of the electronic device 1000 shown, cut along BB. Figure 19b yes Figure 2 The diagram shows a partial cross-sectional view of one embodiment of the electronic device 1000 cut along BB.

[0158] like Figure 19a and Figure 19bAs shown, when the electronic device 1000 is in the closed state, both the screen 300 and the elastic component 100 can be folded relative to each other by the drive of the housing device 200. The second portion 320 of the screen 300 can be bent 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 pivot assembly 210. The second portion 102 of the elastic component 100 can overlap the second connecting portion 212 of the pivot assembly 210.

[0159] In this embodiment, the second adhesive 60 of the elastic component 100 can deform under the pressure of the screen 300. The left and right sides of the second adhesive 60 are compressed along the direction close to the pivot assembly 210, allowing the surface of the second adhesive 60 facing away from the pivot assembly 210 to bend into an arc shape, thus better conforming to the bent screen 300. This provides a smoother supporting environment for the screen 300. In some embodiments, the left and right sides of the first adhesive 40 can also be compressed along the direction close to the pivot assembly 210, allowing the surface of the first adhesive 40 facing away from the pivot assembly 210 to bend into an arc shape, further conforming to the bent screen 300.

[0160] Understandably, compared to traditional electronic devices that sacrifice screen thickness to improve overall structural reliability, resulting in a thicker overall device with greater rebound force when bent, the electronic device 1000 of this embodiment provides 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 support portion and an elastic portion. The support portion can be made of a rigid material, and the elastic portion can be made of an elastic material or a non-Newtonian fluid material. When the electronic device 1000 is in a closed state, the hinge assembly 210 can be located inside the screen 300, and the elastic component 100 can be fixed 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 in an open state, the screen 300, the elastic component 100, and the hinge assembly 210 can be stacked along the thickness direction of the electronic device 1000. Thus, when the electronic device 1000 is dropped, especially when it is in a closed state, the supporting portion of the elastic component 100 can effectively absorb the impact and / or compressive force of the hinge assembly 210 on the screen 300, reducing the impact force on the screen 300 and providing good rigid support for it. The elastic portion of the elastic component 100 can effectively absorb and disperse the impact and / or compressive force applied to the screen 300. The elastic component 100 can effectively absorb the impact force on the second part 320 of the screen 300 caused by the drop, preventing the second part 320 of the screen 300 from colliding violently with the hinge assembly 210, thus 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 assembly 210 can effectively improve the reliability of the screen 300 when it is dropped. 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, thus improving the user's opening and closing experience.

[0161] Secondly, the supporting portion of the elastic component 100 may include at least one support member (i.e., the first support member 10 in this embodiment). The elastic portion of the elastic component 100 may include at least one elastic member (i.e., the first elastic member 20 in this embodiment). The first support 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 is dropped and the second portion 320 of the screen 300 is impacted, the first support member 10 can effectively absorb the impact force and / or compressive force of 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 provide good elasticity against the impact force and / or compressive force applied to the screen 300, while also absorbing and dispersing the impact force and / or compressive force received by the screen 300. In other words, the elastic component 100 of this embodiment includes both a first support member 10 and a first elastic member 20. The first support member 10 and the first elastic member 20 provide good rigid protection and elastic protection for the screen 300, respectively. The entire elastic component 100 has strong impact resistance and compression resistance, which enables the elastic component 100 to better protect the screen 300, improve the drop reliability of the screen 300, and help extend the service life of the screen 300.

[0162] In addition, the elastic component 100 in this embodiment may also 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 can be arranged sequentially and stacked along the direction of the rotating shaft assembly 210 toward the screen 300. The first support member 10 and the second support member 50 can together constitute the support portion of the elastic component 100. The first elastic member 20 and the second elastic member 70 can together constitute the elastic portion of the elastic component 100. Thus, by alternately stacking and arranging multiple support members (i.e., the first support member 10 and the second support member 50 in this embodiment) and multiple elastic members (i.e., the first elastic member 20 and the second elastic member 70 in this embodiment), the entire elastic component 100 can form a structure similar to a bulletproof vest, which is beneficial to improving the impact resistance and compression resistance of the elastic component 100. Compared to directly increasing the thickness of the first support member 10 and the first elastic member 20 to improve the impact and compression resistance of the elastic component 100, the elastic component 100 in this embodiment exhibits better impact and compression resistance under the same thickness conditions. Furthermore, under the same performance conditions, the thickness of each support member and each elastic member of the elastic component 100 in this embodiment is relatively thin, and multiple support members and multiple elastic members are fixed together by adhesive layers. Thus, when the electronic device 1000 bends, a certain degree of misalignment can occur between adjacent support members and elastic members, thereby significantly reducing the rebound force of the entire elastic component 100 when bent. In other words, under certain performance conditions, the thickness of the elastic component 100 in this embodiment can be thinner, which is beneficial for achieving a thinner design of the electronic device 1000. Simultaneously, the total thickness of the elastic portion of the elastic component 100 in this embodiment can be in the 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 compression resistance while having a thin overall thickness, which is conducive to realizing the thin design of the electronic device 1000.

[0163] Furthermore, the elastic component 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. These components can be arranged sequentially and stacked along the direction from the pivot assembly 210 toward the screen 300. In this way, compared to a support member being adjacent to the screen 300, the support member experiences greater rebound force during bending, which can easily damage the screen 300. This embodiment, by providing an elastic member (in this embodiment, the second elastic member 70) adjacent to the screen 300, reduces the rebound force during bending, effectively lowering the probability of damage to the screen 300 and extending the lifespan of the electronic device 1000.

[0164] 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 itself and the thickness of the pivot assembly 210 can be equal to the height difference (i.e., the first distance H1) between the upper surface of the first adhesive 240 of the housing device 200 and the wall of the first mounting groove 221 facing the screen 300 in the thickness direction of the electronic device 1000. In this way, on the one hand, the elastic component 100 can utilize the thickness space of the housing device 200, so that the elastic component 100 can ensure the drop reliability of the screen 300 without increasing the thickness of the entire electronic device 1000, which is conducive to realizing the thin design of the electronic device 1000; on the other hand, there is no height difference between the elastic component 100 and the first adhesive 240 and the second adhesive 250 of the housing device 200, thereby providing a relatively flat support environment for the screen 300, improving the display effect of the screen 300, and enhancing the user experience.

[0165] In some embodiments, the elastic component 100 may simultaneously 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 and stacked along the direction from the pivot assembly 210 toward the screen 300. In this way, compared to an elastic member being adjacent to the screen 300, the elastic member's ability to disperse and / or absorb impact force when the electronic device 1000 is dropped is limited, making the screen 300 more susceptible to damage during a drop. This embodiment, by providing a support member (in this embodiment, the second support member 50) adjacent to the screen 300, allows the support member to better absorb impact force when the electronic device 1000 is dropped, while also providing good rigid support for the screen 300. This effectively reduces the probability of damage to the screen 300 during a drop and helps extend the service life of the electronic device 1000.

[0166] In other embodiments, the elastic component 100 may further include a third support member. The third support member may form 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 form 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 pivot assembly 210. Alternatively, the elastic component 100 may simultaneously include 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 stacked. 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.

[0167] In some other embodiments, the elastic component 100 may also exclude the second support 50, the second elastic component 70, the second adhesive 60 and the third adhesive 80, and the first adhesive 40 may directly connect the first support 10 and the screen 300.

[0168] Figure 20 yes Figure 6 The diagram shows the structure of the first support member 10 in another embodiment.

[0169] like Figure 20 As shown, the structure of the first support member 10 in this embodiment is similar to... Figure 6 The structure of the first support member 10 shown is largely the same, and the identical parts will not be described again. The difference is that the first support member 10 may also have at least one fourth through hole 15. The fourth through hole 15 may be spaced apart from the solder joint 10a. In this embodiment, the number of fourth through holes 15 can be two. The solder joint 10a may be located between the two fourth through holes 15. One of the fourth through holes 15 may be located between the solder joint 10a and an adjacent second through hole 14. The fourth through hole 15 may be an elongated hole 302a. The extending direction of the fourth through hole 15 may intersect with the extending direction of the first support member 10, for example, the extending direction of the fourth through hole 15 may also be perpendicular to the extending direction of the first support member 10.

[0170] It is understandable that when the electronic device 1000 is dropped, the screen 300 will slide due to inertia, and at the same time, it will exert a pulling force on the elastic component 100. When the pulling force acts on the first support member 10, the solder joint 10a between the first support member 10 and the pivot assembly 210 is prone to detachment 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 pivot assembly 210, thereby causing radio frequency interference to the antenna of the electronic device 1000 and affecting the antenna performance of the whole device. In this embodiment, a fourth through hole 15 is provided on the first support member 10 at intervals 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 detaching, which is beneficial to ensuring the connection reliability between the first support member 10 and the pivot assembly 210 and reducing the impact on the antenna performance of the whole device.

[0171] Figure 21 yes Figure 6 The diagram shows the structure of the first support member 10 in another embodiment.

[0172] like Figure 21 As shown, the structure of the first support member 10 in this embodiment is similar to... Figure 6 The structures of the first support member 10 shown are largely the same, and the identical parts will not be described again. The differences between the two will be described below. Exemplarily, at least one corner of the first support member 10 can be chamfered to form at least one clearance space 10c. The clearance space 10c can be used to avoid an antenna within the electronic device 1000. In this embodiment, the first support member 10 can be generally elongated and has four corners. Each of the four corners can be chamfered to form four clearance spaces 10c.

[0173] It is understood that in this embodiment, by cutting the corner of the first support member 10 to form an avoidance space 10c, the edge of the first support member 10 can be kept away from the antenna inside the electronic device 1000, thereby reducing the radio frequency interference of the first support member 10 to the antenna inside the electronic device 1000 and reducing the impact of the first support member 10 on the antenna performance of the whole device.

[0174] In some embodiments, the shape and size of the first elastic member 20 can be the same as that of the first support member 10. The shape and size of the lubricant 30 can also be the same as that of the first support member 10. In other words, both the first elastic member 20 and the lubricant 30 can have their corners trimmed. This allows the first support member 10, the first elastic member 20, and the lubricant 30 to be assembled together and trimmed simultaneously, saving on manufacturing processes and reducing dimensional errors. Furthermore, the consistent shape and size of the first support member 10, the first elastic member 20, and the lubricant 30 effectively avoids stepped areas between them, providing a flat support environment for the screen 300.

[0175] Figure 22 yes Figure 6 The diagram shows the structure of the first support member 10 in another embodiment.

[0176] like Figure 22 As shown, the structure of the first support member 10 in this embodiment is similar to... Figure 6 The structure of the first support member 10 shown is largely the same, and the similar parts will not be described again. The main differences between the two are described below. In this embodiment, the first support member 10 may also have multiple first holes 16 and second holes 17. The number of first holes 16 can be the same as the number of second holes 17. Multiple first holes 16 can all be located in the first portion 11 of the first support member 10. Multiple first holes 16 can be arranged at intervals along the length direction of the first support member 10. Multiple second holes 17 can all be located in the third portion 13 of the first support member 10. Multiple second holes 17 can be arranged at intervals along the length extension direction of the first support member 10. Both first holes 16 and second holes 17 can be elongated holes. The extension directions of both first holes 16 and second holes 17 can intersect the length extension direction of the first support member 10. In this embodiment, the extension directions of both the multiple first holes 16 and the multiple second holes 17 can be perpendicular to the length extension direction of the first support member 10.

[0177] It is understood that, in this embodiment, by providing a plurality of first holes 16 in the first part 11 of the first support member 10 with the extension direction intersecting the length extension direction of the first support member 10, and by providing a plurality of second holes 17 in the third part 13 of the first support member 10 with the extension direction intersecting the length extension direction 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.

[0178] Figure 23 yes Figure 8 The diagram shows the structure of the first elastic element 20 in another embodiment.

[0179] like Figure 23 As shown, the structure of the first elastic element 20 in this embodiment is similar to... Figure 8 The structure of the first elastic element 20 shown is largely the same, and the similarities will not be described again. The main differences between the two are described below. In this embodiment, the first elastic element 20 may include a first end 22 and a second end 23 disposed opposite to each other. Both the first end 22 and the second end 23 may have multiple grooves 24. Taking the first end 22 as an example, the multiple grooves 24 may be spaced apart. The openings of the grooves 24 may face away from the second end 23. In this case, the first end 22 may be approximately serrated or wavy. The configuration of the second end 23 is the same as that of the first end 22, and will not be described again here.

[0180] It is understood that by providing one or more grooves 24 at the first end 22 and the second end 23 of the first elastic member 20 in this embodiment, a release space can be provided for the arching of the first elastic member 20 at its ends (i.e., the first end 22 and the second end 23) caused by the electronic device 1000 falling when it is in the open state. This can effectively avoid the phenomenon that the first elastic member 20 arches at its end edge when it falls when the electronic device 1000 is in the open state, which would cause the screen 300 to arch and the wiring of the screen 300 to break, resulting in the failure of the screen 300. This is beneficial to extending the service life of the screen 300 and improving the user experience.

[0181] In other implementations, such as Figure 24 As shown, the first end 22 may also have only one arc-shaped groove 24. In this case, the first end 22 may be approximately arc-shaped. This application does not specifically limit the shape and number of the groove 24.

[0182] 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 protection scope of this application. That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0183] It should be noted that all the above figures are exemplary illustrations of this application and do not represent the actual size of the product. Furthermore, the dimensional proportions between the components in the figures are not intended to limit the actual product of this application.

[0184] The above are merely some embodiments of this application, and the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
