Description

Technical Field

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

[0002] With the continuous development of flexible display technology, it is widely used in a variety of foldable electronic devices. Among them, electronic devices with foldable screens are more convenient to use and are loved by users. However, whether in the open or closed state, the screen of electronic devices with foldable screens is exposed to the external environment, which greatly increases the probability of screen damage when the electronic device falls.

[0003] Traditional foldable electronic devices usually sacrifice the thickness of the screen to improve the drop reliability of the screen. However, although increasing the thickness of the screen improves the drop reliability of the screen, it also greatly increases the rebound force when the screen is bent, and the opening and closing experience of the electronic device is poor. How to obtain an electronic device with high screen drop reliability and small rebound force has become the current research direction. Summary of the invention

[0004] The embodiments of the present application provide a foldable electronic device, aiming to provide a foldable electronic device and a screen assembly with high screen drop reliability and small rebound force.

[0005] In a first aspect, a foldable electronic device is provided. The electronic device includes a screen, a hinge assembly, a first shell, a second shell and an elastic assembly. The screen is fixedly connected to the first shell and the second shell. The hinge assembly includes a first connecting portion, a second connecting portion and a main shaft portion. The shaft portion connects the first connecting portion and the second connecting portion. The first connecting portion is connected to the first shell. The second connecting portion is connected to the second shell. The elastic assembly includes an elastic portion and a supporting portion. The material of the elastic portion is an elastic material or a non-Newtonian fluid material. The material of the supporting portion is a rigid material. The electronic device has an open state and a closed state. When the electronic device is in the open state, the elastic assembly is flattened. The screen, the elastic assembly and the hinge assembly are stacked in the thickness direction of the electronic device. The elastic portion and the supporting portion are stacked in the thickness direction of the electronic device. The first portion of the elastic assembly overlaps the first connecting portion, and the second portion of the elastic assembly overlaps the second connecting portion. When the electronic device is in the closed state, the elastic assembly is bent, the first portion of the elastic assembly overlaps the first connecting portion, and the second portion of the elastic assembly overlaps the second connecting portion.

[0006] It is understandable that, compared with the traditional electronic device that sacrifices the thickness of the screen to improve the overall structural reliability of the screen, resulting in a thicker overall thickness of the electronic device and a larger rebound force when bent, the electronic device of this embodiment is provided with an elastic component between the screen and the main shaft part of the rotating shaft assembly. Among them, the elastic component may include a supporting part and an elastic part. The material of the supporting part may be a rigid material, and the material of the elastic part may be an elastic material or a non-Newtonian fluid material. When the electronic device is in an open state, the screen, the elastic component and the rotating shaft assembly are stacked along the thickness direction of the electronic device. In this way, when the electronic device falls, the supporting part of the elastic component can better absorb the impact force and / or squeezing force of the rotating shaft assembly on the screen, reduce the impact force on the screen, and provide good rigid support for the screen. The elastic part in the elastic component can play a good elastic role in the impact force and / or squeezing force applied to the screen, and the elastic part can also absorb and disperse the impact force and / or squeezing force on the screen. The elastic component can effectively absorb the impact force of the screen due to falling, and avoid the problem of the screen having broken bright spots and black spots due to strong collision with the hinge component, which is beneficial to improving the structural reliability of the screen and extending the service life of the screen. In other words, the screen in this embodiment does not need to sacrifice its own thickness, and the elastic component located between the screen and the hinge component can effectively improve the reliability of the screen when it falls. At the same time, the overall thickness of the screen is relatively thin, so that the rebound force when the electronic device is bent can be effectively reduced, which is beneficial to improving the user's opening and closing experience.

[0007] In a possible implementation, the support portion includes a first support member. The elastic portion includes a first elastic member. The first support 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 support member facing away from the main shaft portion. The first support 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 an open state, the first part overlaps the first connecting part and can move relative to the first connecting part. The second part is relatively flattened with the first part, and the third part overlaps the second connecting part and can move relative to the second connecting part.

[0008] It is understandable that the supporting part of the elastic component in this embodiment may include at least one supporting member (also referred to as the first supporting member in this embodiment). The elastic part of the elastic component may include at least one elastic member (also referred to as the first elastic member in this embodiment). The material of the first supporting member may be a rigid material, and the material of the first elastic member may be an elastic material or a non-Newtonian fluid material. In this way, when the electronic device falls and the second part of the screen is impacted, the first supporting member can better absorb the impact force and / or the extrusion force of the rotating shaft component on the second part of the screen, reduce the impact force on the screen, and provide good rigid support for the screen. The first elastic member can play a good elastic role in the impact force and / or the extrusion force applied to the screen, and can absorb and disperse the impact force and / or the extrusion force on the screen. In other words, the elastic component of this embodiment includes both the first supporting member and the first elastic member, and the first supporting member and the first elastic member respectively play a good rigid protection and elastic protection role on the screen, and the entire elastic component has a strong impact resistance and extrusion resistance, so that the elastic component can better protect the screen, improve the falling reliability of the screen, and help to extend the service life of the screen.

[0009] In a possible implementation, when the electronic device is in a closed state, the first part overlaps the first connecting part, the second part is bent, and the third part overlaps the second connecting part. When the electronic device switches from an open state to a closed state, the first part moves relative to the first connecting part, the second part is bent relative to the first part, and the third part moves relative to the second connecting part. In this way, whether the electronic device in this embodiment is in an open state or a closed state, the first support member can cover the gap between the main shaft part of the partial shaft assembly and the first connecting part and the gap between the main shaft part of the partial shaft assembly and the second connecting part in the thickness direction of the electronic device, thereby preventing the outer edge of the first support member from interfering with the shaft assembly due to being located at the gap of the shaft assembly, thereby affecting the opening and closing of the electronic device. At the same time, the first support member can overlap the first connecting part and the second connecting part, which is conducive to providing a relatively flat support environment for the fixed assembly of subsequent components.

[0010] In a possible implementation, the main shaft portion has a flat surface. The flat surface is arranged toward the screen, and the second portion of the first support member is fixedly connected to the flat surface. When the electronic device is in an open state, the flat surface is parallel to the screen. In this way, the main shaft portion of the rotating shaft assembly has a relatively flat flat surface, which facilitates the fixation between the elastic assembly and the main shaft portion.

[0011] In a possible implementation, the thickness of the first support member is less than or equal to the thickness of the first elastic member. In this way, the first support member is thinner, which is conducive to reducing the rebound force when the electronic device is bent, thereby improving the opening and closing experience of the electronic device.

[0012] In one possible implementation, the first elastic member is provided with at least one first through hole. The first through hole exposes a portion of the first support member. The elastic component also includes at least one first adhesive. The first adhesive is located in the first through hole and connects the first support member and the screen. In this way, the first adhesive can utilize the thickness space of the first elastic member, so that the thickness of the elastic component will not be increased while other components are fixed, which is conducive to the thin design of the electronic device. At the same time, the through hole on the first elastic member (that is, the first through hole in this embodiment) can also be used to control the thickness of the first adhesive, so as to avoid the problem that the first adhesive is too thin to ensure the connection stability of other components, and avoid the problem that the first adhesive is too thick to cause the screen to be uneven.

[0013] In a possible implementation, the first support member is provided with at least one second through hole. The second through hole exposes a portion of the main shaft portion. The second through hole is connected to the first through hole. The opening size of the second through hole is not greater than the opening size of the first through hole. When the electronic device is in an open state, the first through hole and the second through hole at least partially overlap in the thickness direction of the electronic device. The first adhesive is located in 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 understandable 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 equal to the opening of the first through hole, the second through hole can also expose part of the main shaft exposed by the first through hole, so that the first adhesive can realize the fixed connection between other parts and the rotating 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 member is fixed by the first adhesive, on the one hand, the opening of the second through hole is relatively small, and the second through hole only exposes a portion of the flat surface a of the shaft assembly, so that the first adhesive can realize the fixed connection between the second support member and the shaft assembly, while the first adhesive will not overflow from the second through hole to other components of the shaft assembly, thereby effectively avoiding the problem of other components sticking to each other due to the overflow of the first adhesive; on the other hand, the opening of the first through hole is larger than the opening of the second through hole, so that the second support member can be directly fixedly connected to the shaft assembly by the first adhesive, and can also be fixedly connected to the upper surface of the first support member by the first adhesive, so as to increase the fixing area of ​​the first adhesive and the first support member, thereby effectively improving the connection stability between the second support member and the shaft assembly, and also improving the connection stability between the second support member and the first support member, which is beneficial to improving the overall structural stability of the electronic device.

[0015] In a possible implementation, the support portion further includes a second support member. When the electronic device is in an open state, the second support member is stacked between the first elastic member and the screen in the thickness direction of the electronic device. In this way, the number of support members of the elastic component is large, so that the entire support portion can better absorb the impact force and / or squeezing force of the hinge component on the screen, reduce the impact force on the screen, and provide good rigid support for the screen, which is conducive to improving the reliability of the screen when it falls and extending the service life of the electronic device.

[0016] In a possible implementation, when the electronic device is in an open state, the width of the gap between the first connection portion and the second connection portion in the first direction is greater than or equal to the width of the second support member in the first direction. In this way, the width of the second support member is narrow, thereby effectively reducing the rebound force when the second support member is bent, and the opening and closing of the electronic device is smoother, which is conducive to improving the user experience.

[0017] In a possible implementation, the elastic component also includes a second adhesive. The second adhesive connects the second support member and the screen. When the electronic device is in an open state, the second adhesive is stacked between the second support member and the screen in the thickness direction of the electronic device. When the electronic device is in an open state, the direction in which the first shell points to the second shell is a first direction, and in the first direction, the width of the second adhesive is less than or equal to the width of the second support member. In this way, most of the second adhesive can be located directly above the main shaft portion of the hinge assembly, and the width of the second adhesive is narrow, thereby effectively reducing the rebound force when the second adhesive is bent, which is beneficial to improving the opening and closing experience of the electronic device.

[0018] In a possible implementation, the elastic part further includes a second elastic member. The second elastic member is fixed between the second support member and the screen. The first support member, the first elastic member, the second support member and the second elastic member are arranged in sequence along the direction of the rotating shaft assembly pointing to the screen.

[0019] It is understandable 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 may be arranged in sequence along the direction of the rotating shaft assembly toward the screen, and may be stacked. Wherein, the first support member and the second support member may jointly constitute the support portion of the elastic component. The first elastic member and the second elastic member may jointly constitute the elastic portion of the elastic component. In this way, by alternately stacking and arranging a plurality of support members (i.e., the first support member and the second support member in this embodiment) and a plurality of elastic members (i.e., the first elastic member and the second elastic member in this embodiment) in the elastic component, the entire elastic component may form a structure similar to a bulletproof vest, which is conducive to improving the impact resistance and extrusion resistance of the elastic component. Compared with directly increasing the thickness of the first support member and the thickness of the first elastic member to improve the impact resistance and extrusion resistance of the elastic component, the elastic component in this embodiment has better impact resistance and extrusion resistance under the same thickness conditions. Under the same performance conditions, the thickness of each support member and each elastic member of the elastic component in this embodiment is relatively thin, and multiple support members and multiple elastic members are fixed to each other by a glue layer. In this way, when the electronic device is bent, a certain displacement can occur between adjacent support members and elastic members, thereby greatly reducing the rebound force of the entire elastic component when it is bent. In other words, under certain performance conditions, the thickness of the elastic component in this embodiment can be thinner, which is conducive to the thin design of the electronic device. At the same time, the total thickness of the elastic part of the elastic component in this embodiment can be in the range of .mm to .mm, and the total thickness of the support part can be less than or equal to the total thickness of the elastic part. In this way, the elastic component can have good impact resistance and extrusion resistance while having a thin total thickness, which is conducive to the thin design of the electronic device.

[0020] Secondly, compared with the case where the support member is arranged adjacent to the screen, the rebound force of the support member when bent is larger, which can easily damage the screen when bent. In this embodiment, an elastic member (also known as the second elastic member in this embodiment) can be arranged adjacent to the screen. The rebound force of the elastic member when bent is smaller, thereby effectively reducing the chance of damage to the screen when bent, which is beneficial to extending the service life of the electronic device.

[0021] In a possible implementation, the support portion includes a first support member and a second support member. The elastic portion includes a first elastic member and a second elastic member. The first elastic member, the first support member, the second elastic member and the second support member are arranged in sequence along a direction in which the rotating shaft assembly points toward the screen.

[0022] It is understandable that the elastic component in this embodiment can include a first support member, a first elastic member, a second support member and a second elastic member at the same time, and the first elastic member, the first support member, the second elastic member and the second support member can be arranged in sequence along the direction of the rotating shaft assembly toward the screen, and can be stacked. In this way, compared with the elastic member being arranged adjacent to the screen, the elastic member has limited ability to disperse and / or absorb impact force when the electronic device falls, which can easily damage the screen when it falls. In this embodiment, the support member (also the second support member in this embodiment) can be arranged adjacent to the screen. When the electronic device falls, the support member can better absorb the impact force and provide good rigid support for the screen, thereby effectively reducing the probability of damage to the screen when it falls, which is conducive to extending the service life of the electronic device.

[0023] In a possible implementation, the elastic component further includes a third adhesive. The third adhesive is connected between the second elastic member and the screen. When the electronic device is in an open state, in the first direction, the width of the third adhesive is equal to the width of the second elastic member. In this way, the third adhesive can achieve fixation between the second elastic member and the screen while having little effect on the rebound force when the electronic device is bent, which is conducive to improving the opening and closing experience of the electronic device.

[0024] In a possible implementation, the screen includes a first part, a second part, and a third part arranged in sequence along a first direction. The first part is connected to the first shell. The third part is connected to the second shell. The second part is connected between the first part and the third part. When the electronic device is in an open state, the screen is flattened, and the first part, the second part, and the third part are arranged in sequence along the first direction. In the thickness direction of the electronic device, the second part and the shaft assembly are stacked. The width of the second elastic member in the first direction is greater than or equal to the width of the second part in the first direction. When the electronic device is in a closed state, the first part and the third part are folded relative to each other, and the second part is bent. In this way, the second elastic member and the third adhesive can enhance the rigidity of the screen, thereby effectively avoiding the problem that the electronic device falls when in an open state, causing a part of the screen to arch, which is beneficial to improving the overall structural strength of the screen and extending the service life of the screen.

[0025] In a possible implementation, the elastic component further includes a lubricating member. The lubricating member is fixedly connected to the surface of the first elastic member facing away from the first support member. In this way, by providing the lubricating member, the friction coefficient between the first elastic member and other components located above it can be effectively reduced, which is conducive to improving the opening and closing experience of the electronic device.

[0026] In a possible implementation, the lubricating member includes a main body, a first bending portion, and a second bending portion. The main body connects the first bending portion and the second bending portion. The first bending portion includes a first connecting portion and a first extending portion. The second bending portion includes a second connecting portion and a second extending portion. When the electronic device is in an open state, the first extending portion and the main body are spaced apart in the thickness direction of the electronic device. The second extending portion and the main body are spaced apart in the thickness direction of the electronic device. The first extending portion and the second extending portion are located on the side of the main body facing the shaft assembly. The first extending portion and the second extending portion are spaced apart. The first connecting portion connects the main body and the first extending portion. The second connecting portion connects the main body and the second extending portion. The main body, the first connecting portion, and the first extending portion form a first semi-enclosed accommodating space. The main body, the second connecting portion, and the second extending portion form a second semi-enclosed accommodating space. Part of the first elastic member and the first portion of at least part of the first support member are located in the first semi-enclosed accommodating space. Part of the first elastic member and the third portion of at least part of the first support member are located in the second semi-enclosed accommodating space.

[0027] It can be understood that, compared with the case where two lubricating parts are respectively arranged 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, the outer edge of the first support member is exposed to the external environment. The lubricating part in this embodiment can have a main body covering the surface of the first elastic member facing away from the first support member, and also have a first bending part bent toward the first part of the first support member and a second bending part bent toward the third part of the first support member. In this way, the lubricating part can not only cover the surface of the first elastic member, the surface of part of the first part of the first support member, and the surface of part of the third part of the first support member at the same time, but also wrap the outer edges of the first elastic member and the first support member, so that the lubricating part can also protect the outer edges of the first elastic member and the first support member, and avoid the outer edges of the first elastic member and the first support member from scratching with other parts and producing abnormal noise. At the same time, the thickness of the first support member is thin and its outer edge is sharp. By arranging a lubricating member to wrap the outer edge of the first support member (in the present embodiment, that is, the edge of the first part of the first support member away from the third part and the edge of the third part away from the first part), it can also effectively prevent the edge of the first support member from scratching assemblers during the installation of the first support member with other components, which is beneficial to improving the safety of the assembly process.

[0028] In a possible implementation, when the electronic device is in an open state, in the thickness direction of the electronic device, the main body, the first elastic member, the first portion of the first support member, and the first extension are stacked in sequence. The first connecting portion is arranged on the side of the first portion of the first support member away from the third portion of the first support member. The main body, the first elastic member, the third portion of the first support member, and the second extension are stacked in sequence. The second connecting portion is arranged on the side of the third portion of the first support member away from the first portion of the first support member. In this way, the lubricating member can better wrap the outer edge of the first support member, thereby effectively preventing the outer edge of the first support member from scratching against other components and generating abnormal noise.

[0029] In a possible implementation, the first elastic member extends in a direction that includes a first end and a second end that are arranged opposite to each other. The first end is provided with at least one groove. The opening direction of the groove is the direction in which the second end points to the first end.

[0030] It can be understood that in this embodiment, by providing one or more grooves at the first end and the second end of the first elastic member, a release space can be provided for the first elastic member to bulge at its ends (that is, the first end and the second end) when the electronic device falls when in the open state. This can effectively avoid the problem that the first elastic member bulges at the edges of its ends when the electronic device falls when in the open state, causing the screen to bulge, resulting in the breakage of the screen wiring and causing the screen to fail. This is beneficial to extending the service life of the screen and improving the user experience.

[0031] In a possible implementation, a first portion of the first support member is provided with a plurality of first holes. The plurality of first holes are arranged at intervals along the length extension direction of the first support member. A third portion of the first support member is provided with a plurality of second holes, and the plurality of second holes are arranged at intervals along the length extension direction of the first support member. The length extension direction of the first holes and the length extension direction of the second holes both intersect with the length extension direction of the first support member.

[0032] It can be understood that in this embodiment, by providing a plurality of first holes whose extension directions intersect with the length extension direction of the first support member on the first part of the first support member, and providing a plurality of second holes whose extension directions intersect with the length extension direction of the first support member on the third part of the first support member, the rebound force of the first support member when bent can be effectively reduced, which is beneficial to improving the opening and closing experience of the electronic device.

[0033] In a possible implementation, the first support member is in the shape of an elongated strip, and at least one corner of the first support member has an escape space.

[0034] It can be understood that in this embodiment, the avoidance space c is formed by trimming the corners of the first support member so that the edge of the first support member can be away from the antenna inside the electronic device, thereby reducing the radio frequency interference of the first support member on the antenna inside the electronic device and reducing the impact of the first support member on the antenna performance of the entire device.

[0035] In a possible implementation, the thickness of the support portion is less than or equal to the thickness of the elastic portion. Thus, the total thickness of the support portion can be less than or equal to the total thickness of the elastic portion. Thus, the elastic component can have good impact resistance and extrusion resistance while having a relatively thin total thickness, which is conducive to realizing a thin design of the electronic device.

[0036] In a possible implementation, the hinge assembly is located on the inner side of the screen. In this way, the electronic device can be a screen-folding electronic device. When the electronic device falls, especially when the electronic device falls in a closed state, the supporting part of the elastic assembly can better absorb the impact force and / or squeezing force of the hinge assembly on the screen, reduce the impact force on the screen, and provide good rigid support for the screen. The elastic part in the elastic assembly can play a good elastic role in the impact force and / or squeezing force applied to the screen, and the elastic part can also absorb and disperse the impact force and / or squeezing force on the screen. The elastic assembly can effectively absorb the impact force of the screen due to falling, avoid the problem of the screen having broken bright spots and black spots due to strong collision with the hinge assembly, which is conducive to improving the structural reliability of the screen and extending the service life of the screen. In other words, the screen in this embodiment does not need to sacrifice its own thickness, and the reliability of the screen when it falls can be effectively improved by the elastic assembly located between the screen and the hinge assembly. At the same time, the overall thickness of the screen is thin, so that the rebound force when the electronic device is bent can be effectively reduced, which is conducive to improving the user's opening and closing experience.

[0037] In a possible implementation, the first shell includes a first mounting groove. The second shell includes a second mounting groove. When the electronic device is in an open state, the first mounting groove and the second mounting groove form a receiving space. At least part of the shaft assembly and at least part of the elastic assembly are located in the receiving space. In this way, at least part of the elastic assembly can be located in the receiving space. On the one hand, the elastic assembly can utilize the thickness space of the shell device, so that the elastic assembly can ensure the drop reliability of the screen while not increasing the thickness of the entire electronic device, which is conducive to realizing a thin design of the electronic device; on the other hand, there is no height difference between the elastic assembly and the first adhesive backing and the second adhesive backing of the shell device, thereby providing a relatively flat supporting environment for the screen, improving the display effect of the screen, and improving the user experience.

[0038] In a second aspect, a screen assembly is provided. The screen assembly includes a screen and at least one elastic member. The screen includes a first part, a second part and a third part, and the second part is connected between the first part and the third part. The elastic member is located on the non-display side of the screen, and part of the elastic member is fixedly connected to the second part. The material of the elastic member is an elastic material or a non-Newtonian fluid material. The width of the elastic member in the first direction is less than the width of the screen in the first direction. The first direction is the direction in which the first part points to the second part when the screen assembly is in an open state.

[0039] It is understandable that, compared with stacking the elastic member and the screen in sequence and fixing them on the hinge assembly of the electronic device, in this embodiment, the elastic member and the screen are first assembled together to form a screen assembly, and then the entire screen assembly is fixed together on the hinge assembly. In this way, the screen can provide a relatively flat supporting environment during the assembly process of the elastic member, making it easier for the elastic member to be assembled on the screen, and it is also helpful to reduce the bubbles in the adhesive between the elastic member and the screen, thereby effectively improving the connection stability between the elastic member and the screen, and effectively avoiding the problem of debonding and stratification of the elastic member and the screen at the bubble due to multiple opening and closing of the electronic device, which is helpful to improve the overall structural stability of the electronic device and extend the service life of the electronic device.

[0040] In a possible implementation, the width of the elastic member in the first direction is greater than or equal to the width of the bent portion in the first direction. In this way, the elastic member can enhance the rigidity of the screen, thereby effectively preventing the electronic device from falling when in the open state, causing a portion of the screen to bulge, which is beneficial to improving the overall structural strength of the screen and extending the service life of the screen.

[0041] In one possible implementation, the screen assembly also includes at least one support member. The support member is fixedly connected to the surface of the elastic member facing away from the screen, and the material of the support member is a rigid material. The width of the support member in the first direction is less than or equal to the width of the elastic member in the first direction. In this way, the screen can provide a relatively flat support environment during the assembly process of the support member, making the support member easier to assemble on the screen, and it is also beneficial to reduce the bubbles in the adhesive between the support member and the elastic member, thereby effectively improving the connection stability between the support member and the elastic member, and can also effectively avoid the problem of debonding and stratification of the support member and the elastic member at the bubble due to multiple opening and closing of the electronic device, which is beneficial to improve the overall structural stability of the electronic device and extend the service life of the electronic device.

[0042] In a possible implementation, the thickness of the support member is less than or equal to the thickness of the elastic member. In this way, the thickness of the support member is thinner, which can effectively reduce the rebound force when the support member is bent, and the opening and closing of the electronic device is smoother, which is conducive to improving the user experience.

[0074] The embodiments of the present application are described below in conjunction with the accompanying drawings in the embodiments of the present application.

[0075] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed connection" means that the relative position relationship after connection remains unchanged. "Rotational connection" means that the two are connected to each other and can rotate relative to each other after connection. "Sliding connection" means that the two are connected to each other and can slide relative to each other after connection. The directional terms mentioned in the embodiments of the present application, such as "up", "down", "left", "right", "inside", "outside", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application. "Multiple" means at least two.

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

[0077] In the implementation manner of the present application, "and / or" is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0078] References to "one embodiment" or "some embodiments" etc. described in this specification mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0079] It is to be understood that the specific implementations described herein are only used to explain the relevant invention, rather than to limit the invention. It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings.

[0080] Figure 1 It is a schematic diagram of the structure of the electronic device 1000 provided in an embodiment of the present application when it is in an open state. Figure 2 yes Figure 1 The structure diagram of the electronic device 1000 shown is in a closed state.

[0081] like Figure 1 and Figure 2 As shown, the electronic device 1000 may include a housing device 200 and a screen 300. The screen 300 may be mounted on the housing device 200. The housing device 200 may be in a Figure 1 The open state shown, and Figure 2The closed state shown. The housing device 200 can also be in an intermediate state between unfolding or folding. Among them, the intermediate state can be any state between the open state and the 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 be unfolded to an open state, or folded to a closed state. Among them, when the electronic device 1000 is in a closed state, the housing device 200 can be located on the inner side of the screen 300. In other words, the electronic device 1000 can be an electronic device 1000 with a foldable screen. For ease of understanding, the direction that is the same as the light emitting direction of the screen 300 is defined as "up", and the direction opposite to the light emitting direction of the screen 300 is defined as "down". In some embodiments, the electronic device 1000 can also be an electronic device with a foldable screen.

[0082] In this embodiment, when the electronic device 1000 is in an open state, the screen 300 can be flattened. At this time, the screen 300 can be displayed in full screen, and the electronic device 1000 has a large display area, which is conducive to improving the user's viewing experience and operation experience. When the electronic device 1000 is in a closed state, the plane size of the electronic device 1000 is small, which is convenient for the user to carry and store.

[0083] Exemplarily, the screen 300 may be integrated with a display function and a touch sensing function. The display function of the screen 300 is used to display images, videos, etc., and the touch sensing function of the screen 300 is used to sense the user's touch action to achieve human-computer interaction. Exemplarily, the screen 300 includes a flexible display screen that can be bent. Among them, the flexible display screen can use a liquid crystal display (LCD), an organic light-emitting diode (OLED) display screen, an active matrix organic light-emitting diode or an active matrix organic light-emitting diode (AMOLED) display screen, a flexible light-emitting diode (FLED) display screen, a MiniLED display screen, a MicroLED display screen, a Micro-OLED display screen, a quantum dot light emitting diode (QLED) display screen, etc.

[0084] Exemplarily, the electronic device 1000 may further include multiple components (not shown in the figure), and the multiple components are installed inside the housing device 200. The multiple components may include, for example, a processor, an internal memory, an external memory interface, a universal serial bus (USB) interface, a charging management module, a power management module, a battery, an antenna, a communication module, a camera, an audio module, a speaker, a receiver, a microphone, an earphone interface, a sensor module, a button, a motor, an indicator, and a subscriber identification module (SIM) card interface.

[0085] It should be understood that Figure 1 and Figure 2 Only some components of the electronic device 1000 are schematically shown, and the actual shapes, sizes and structures of these components are not limited to the following. Figure 1 and Figure 2 In other implementations, when the electronic device 1000 is a device in another form factor, the electronic device 1000 may not include the screen 300 .

[0086] In this embodiment, the electronic device 1000 is taken as an example of a two-fold structure, that is, the electronic device 1000 includes two flat parts and a bent part connected between the two flat parts. Among them, the two flat parts can be rotated toward each other to overlap each other (corresponding to the closed state in the previous text), so that the electronic device 1000 presents a two-layer form; the two flat parts can also be rotated away from each other to be flattened (corresponding to the open state in the previous text). In other embodiments, the electronic device 1000 can also be a structure of more than three folds, that is, the electronic device 1000 includes more than three flat parts, and two adjacent flat parts are connected by a bent part, and the two adjacent flat plates can be rotated relative to each other to overlap each other or rotated away from each other to be flattened. When the electronic device 1000 is a structure of more than three folds, the structure of the electronic device 1000 can refer to the description of the two-fold structure of this embodiment for adaptive design, and this application will not repeat it.

[0087] Figure 3 yes Figure 1 The illustrated electronic device 1000 is a schematic diagram of a partially exploded structure in some implementations. Figure 4 yes Figure 1 The partial cross-sectional structure diagram of a partial structure of the electronic device 1000 in one embodiment is shown cut along AA. Figure 5 yes Figure 2 The partial cross-sectional structure diagram of a partial structure of the electronic device 1000 in one embodiment is shown cut along line BB.

[0088] like Figures 3 to 5As shown, the housing device 200 may include a shaft assembly 210, a first housing 220 and a second housing 230. The shaft assembly 210 may connect the first housing 220 and the second housing 230. The shaft assembly 210 may move so that the first housing 220 and the second housing 230 can be relatively unfolded to an open state, or relatively folded to a closed state. It should be understood that the first housing 220 and the second housing 230 are both housing members, which are used to install and fix other components of the electronic device 1000 and have a variety of structures. The shaft assembly 210 is used to achieve relative movement between the first housing 220 and the second housing 230, and also has a variety of structures. The embodiment of the present application does not strictly limit the specific structure of the first housing 220, the second housing 230 and the shaft assembly 210. The drawings of the present application only illustrate the general structure of the first housing 220, the second housing 230 and the shaft assembly 210 in one embodiment.

[0089] Exemplarily, the shaft assembly 210 may include a first connecting portion 211, a second connecting portion 212, and a main shaft portion 213. The first connecting portion 211 and the second connecting portion 212 may be substantially symmetrical structures. The first connecting portion 211 and the second connecting portion 212 may both be connected to the main shaft portion 213. The first connecting portion 211 and the second connecting portion 212 may both move relative to the main shaft portion 213 to achieve relative unfolding and relative folding.

[0090] Exemplarily, the upper surface of the main shaft portion 213 may be roughly in the form of an arc. Among them, the part of the upper surface of the main shaft portion 213 located at the top of the arc may be a plane, constituting a flat surface 213a of the main shaft portion 213. That is, the flat surface 213a may be arranged close to the screen 300. At this time, the upper surface of the main shaft portion 213 may be in the form of an incomplete arc. The flat surface 213a may coincide with the central axis of the main shaft portion 213 in the thickness direction of the rotating shaft assembly 210, that is, the flat surface 213a may be located in the middle of the main shaft portion 213. In some embodiments, the first connecting portion 211 and the second connecting portion 212 may both include a connecting member for realizing movement and a support plate for realizing support. Among them, the support plate may be located above the connecting member.

[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 rotating shaft assembly 210 may be located in the first mounting groove 221 and connected to the first housing 220. The second connecting portion 212 of the rotating shaft assembly 210 may also be located in the second mounting groove 231 and connected to the second 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 may be fixedly connected to the upper surface of the first housing 220. The second adhesive 250 may be fixedly connected to the upper surface of the second housing 230. Both the first adhesive 240 and the second adhesive 250 may be used to fix the screen 300.

[0093] When the electronic device 1000 is in an 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 be connected to the second mounting groove 231. The first mounting groove 221 and the second mounting groove 231 can together constitute the receiving space 200a of the housing device 200. At least part of the hinge assembly 210 can be located in 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 the first width L1. The distance between the first connecting portion 211 and the second connecting portion 212 of the hinge assembly 210 is the second width L2. Among them, a part of the main shaft portion 213 can be located in the first mounting groove 221. Another part of the main shaft portion 213 may be located in the second mounting groove 231. The first connecting portion 211 and the second connecting portion 212 may be located on both sides of the main shaft portion 213, respectively, and relatively flat. In some embodiments, the first connecting portion 211 may also include a first support plate for achieving support and a first connecting body for connecting the first shell 220. The first support plate may be fixed to the surface of the first connecting body facing the screen 300. The second connecting portion 212 may also include a second support plate for achieving support and a second connecting body for connecting the second shell 230. The second support plate may be fixed to the surface of the second connecting body facing the screen 300. When the distance between the first supporting plate and the second supporting plate is less than or equal to the distance between the first connecting body and the second connecting body, the second width L2 is the distance between the first supporting plate of the first connecting portion 211 and the second supporting plate of the second connecting portion 212. When the distance between the first supporting plate and the second supporting plate is greater than the distance between the first connecting body and the second connecting body, the second width L2 is the distance between the first connecting body of the first connecting portion 211 and the second connecting body of the second connecting portion 212.

[0094] When the electronic device 1000 is in a closed state, the first housing 220 and the second housing 230 can be folded relative to each other. The first connecting portion 211 and the second connecting portion 212 of the hinge assembly 210 can be folded relative to each other and 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 attached to the lower surface of the second housing 230. In other embodiments, when the electronic device 1000 is in a closed state, there can also be a gap between the lower surface of the first housing 220 and the lower surface 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 to 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 in the figure). Unless otherwise specified in the following text of this application, the width direction of a component is Figure 4 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 again Figure 3 , the electronic device 1000 may further include an elastic component 100. The elastic component 100 may be fixed between the screen 300 and the hinge component 210. When the electronic device 1000 is in an open state, the screen 300, the elastic component 100 and the hinge component 210 may be stacked in sequence. The elastic component 100 may be used to improve the reliability of the screen 300 when the electronic device 1000 falls. Among them, the elastic component 100 may include an elastic part and a supporting part. The elastic part and the supporting part may 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. Among them, the elastic part may include at least one elastic member. The supporting part may include at least one supporting member. When the elastic part includes only one elastic member and the supporting part also includes only one supporting member, the elastic member may be stacked with the supporting member along the thickness direction of the electronic device 1000. When the elastic part includes multiple elastic members and the supporting part includes multiple supporting members, the multiple elastic members and the multiple supporting members may be alternately and stacked in sequence.

[0097] When the electronic device 1000 falls and the screen 300 is hit, the supporting part of the elastic component 100 can better absorb the impact force and / or squeezing force of the hinge component 210 on the screen 300, reduce the impact force on the screen 300, and provide good rigid support for the screen 300. The elastic part in the elastic component 100 can play a good elastic role in the impact force and / or squeezing force applied to the screen 300, and the elastic part can also absorb and disperse the impact force and / or squeezing force on the screen 300. In other words, the elastic component 100 in this embodiment includes both the elastic part and the supporting part, and the elastic part and the supporting part can respectively play a good rigid protection and elastic protection role for the screen 300. The entire elastic component 100 has a strong impact resistance and squeezing resistance, so that the elastic component 100 can better protect the screen 300, improve the falling reliability of the screen 300, and help to 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 lubricating member 30, a first adhesive 40, a second support member 50, a second adhesive 60, a second elastic member 70 and a third adhesive 80. That is, the support portion of the elastic component 100 may include two support members. The elastic portion of the elastic component 100 may include two elastic members. Among them, when the electronic device 1000 is in an open state, the first support member 10, the first elastic member 20, the lubricating member 30, the second support member 50, the second adhesive 60, the second elastic member 70 and the third adhesive 80 can be stacked and arranged in sequence along the direction of the rotating shaft assembly 210 toward the screen 300.

[0099] When the electronic device 1000 is in the open state, each component 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 When the electronic device 1000 is in a closed state, all components of the elastic component 100 can be in a closed state accordingly. In some other embodiments, the elastic component 100 may also not include the second elastic member 70, the second support member 50, the second adhesive 60, the lubricating member 30 and the third adhesive 80.

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

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

[0102] like Figure 6 As shown, the first support member 10 can be made of a rigid material with certain strength and hardness. The first support member 10 can be in the form of a thin sheet. For example, the first support member 10 can be a steel sheet. The first support member 10 can be bent under the action of an external force. Of course, under the condition of 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, a stainless steel sheet, a titanium alloy sheet, an aluminum alloy sheet, a copper alloy sheet, etc., and this application does not strictly limit this.

[0103] Exemplarily, the first support member 10 may be substantially rectangular. The first support member 10 may include a first portion 11, a second portion 12, and a third portion 13. The second portion 12 may be connected between the first portion 11 and the third portion 13. At this time, the first portion 11, the second portion 12, and the third portion 13 may be arranged in sequence along the width direction of the first support member 10. It should be understood that 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 dotted lines. Although the first support member 10 is divided into three parts for description in this embodiment, it does not affect that the first support member 10 can be an integrally formed 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 formed.

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

[0105] like Figure 7 As shown, the material of the first elastic member 20 can be an elastic material or a non-Newtonian fluid material. Among them, the elastic material can be a material with a certain elasticity such as thermoplastic polyurethane elastomer (Thermoplastic Urethane, TPU). The elastic modulus of the elastic material can be much smaller than the elastic modulus of the rigid material. For example, the elastic modulus of the thermoplastic polyurethane elastomer can be between 0.01GPa and 1GPa. The elastic modulus of stainless steel can be around 200GPa. Among them, the non-Newtonian fluid material refers to a material with a nonlinear relationship between shear stress and shear strain rate. The hardness of the elastic material can be much greater than the hardness of the non-Newtonian fluid.

[0106] Exemplarily, the thickness of the first elastic member 20 may be greater than or equal to the thickness of the first support member 10. The thickness of the first elastic member 20 may be in the range of 0.02 mm to 0.15 mm. For example, the thickness of the first elastic member 20 may 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 is conducive to reducing the rebound force when the electronic device 1000 is bent.

[0107] Exemplarily, the first elastic member 20 may be located above the first support member 10. In this case, the first support member 10 and the first elastic member 20 may be stacked in the second direction. The second direction is the thickness direction of the electronic device 1000 when the electronic device 1000 is in the open state. It should be understood that the second direction referred to hereinafter may be applicable to the above definition.

[0108] Exemplarily, the shape of the first elastic member 20 may be substantially the same as the shape of the first support member 10. The width of the first elastic member 20 may be the same as the width of the first support member 10. The first elastic member 20 may be fixedly connected to the upper surface of the first support member 10 by bonding or the like. When the material of the first elastic member 20 is a thermoplastic polyurethane elastomer, a layer of adhesive may be brushed on the surface of the first elastic member 20, and the first elastic member 20 may be fixedly connected to the first support member 10 by the adhesive. When the material of the first elastic member 20 may be a viscous non-Newtonian fluid material, the first elastic member 20 may be directly bonded and fixed to the upper surface of the first support member 10.

[0109] Figure 8 yes Figure 3 The schematic diagram of the exploded structure of the first support member 10, the first elastic member 20 and the lubricating member 30 of the elastic component 100 is shown. Figure 9a yes Figure 1 The partial cross-sectional structure diagram of a partial structure of the electronic device 1000 in one embodiment is shown cut along AA. Figure 9b yes Figure 9a A schematic diagram of the structure shown after being turned upside down.

[0110] like Figures 8 to 9a As shown, the lubricating component 30 may be Mylar, such as insulating Mylar. The surface of the lubricating component 30 is relatively smooth and has a low surface roughness. The lubricating component 30 may include a main body 31, a first bending portion 32, and a second bending portion 33. The main body 31 may connect the first bending portion 32 and the second bending portion 33. It should be understood that although the lubricating component 30 is divided into three parts for description in this embodiment, it does not affect the lubricating component 30 being an integrally formed structure, that is, the main body 31, the first bending portion 32, and the second bending portion 33 of the lubricating component 30 may be integrally formed. It should be noted that Figure 9a and Figure 9b In the figure, the main body 31 , the first bending portion 32 and the second bending portion 33 of the lubricating member 30 are schematically divided by dotted lines.

[0111] Exemplarily, 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 (please refer to Figure 3). The first bending portion 32 may include a first connecting portion 321 and a first extending portion 322. The first extending portion 322 may be located on a side of the second surface 31b of the main body 31 away from the first surface 31a. The first extending portion 322 may be spaced apart from the main body 31 in the second direction. The first extending portion 322 may include a third surface 322a and a fourth surface 322b that are disposed opposite to each other. The third surface 322a is a surface of the first extending portion 322 facing the main body 31. The fourth surface 322b is a surface of the first extending portion 322 facing away from the main body 31, that is, the fourth surface 322b is a surface of the first extending portion 322 facing the rotating shaft assembly 210. The end of the first extending portion 322 away from the first connecting portion 321 is the first end 322c. The first connecting portion 321 may connect the main body 31 and the first extending portion 322. At this time, the main body 31, the first connecting portion 321 and the first extending portion 322 can collectively enclose a first semi-enclosed accommodating space 32a, that is, the main body 31 and the first bent portion 32 can collectively enclose a first semi-enclosed accommodating space 32a. It should be noted that: Figure 9a and Figure 9b In the figure, the first connecting portion 321 and the first extending portion 322 of the first bending portion 32 are schematically divided by dotted lines.

[0112] Exemplarily, the second bending portion 33 may include a second connecting portion 331 and a second extending portion 332. The second extending portion 332 may be located on a side of the second surface 31b of the main body 31 away from the first surface 31a. The second extending portion 332 may be spaced apart from the main body 31 in the second direction. The second extending portion 332 may include a fifth surface 332a and a sixth surface 332b that are disposed opposite to each other. The fifth surface 332a is a surface of the second extending portion 332 facing the main body 31. The sixth surface 332b is a surface of the second extending portion 332 facing away from the main body 31, that is, the sixth surface 332b is a surface of the second extending portion 332 facing the rotating shaft assembly 210. The end of the second extending portion 332 away from the second connecting portion 331 is the second end 332c. The second connecting portion 331 may connect the main body 31 and the second extending portion 332. At this time, the main body 31, the second connecting portion 331 and the second extending portion 332 can jointly enclose the second semi-enclosed accommodating space 33a, that is, the main body 31 and the second bent portion 33 can jointly enclose the second semi-enclosed accommodating space 33a. At this time, the second extending portion 332 and the first extending portion 322 can be located on the same side of the main body 31. The second extending portion 332 and the first extending portion 322 can be spaced apart along the width direction of the lubricating member 30. It should be noted that, Figure 9a and Figure 9b In the figure, the second connecting portion 331 and the second extending portion 332 of the second bending portion 33 are schematically divided by dotted 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 bonding or the like. The shape of the main body 31 of the lubricating member 30 can be substantially the same as that of the first elastic member 20. The width of the main body 31 of the lubricating member 30 can be the same as that of the first elastic member 20.

[0114] Exemplarily, the first bending portion 32 of the lubricating member 30 can be bent relative to the main body 31 to contact the lower surface of the first part 11 of the first support member 10. Among them, the first extension portion 322 of the first bending portion 32 can be located on the side of the first support member 10 facing away from the first elastic member 20. The third surface 322a of the first extension portion 322 can be fixedly connected to the lower surface of the first part 11 of the first support member 10 by bonding or the like. The first end 322c of the first extension portion 322 can face the second extension portion 332. The first connecting portion 321 can be arranged on the side of the first part 11 of the first support member 10 away from the third part 13. At this time, the main body 31 of the lubricating member 30, the first elastic member 20, the first part 11 of the first support member 10 and the first extension portion 322 of the lubricating member 30 can be stacked in sequence along the second direction. At this time, part of the first elastic member 20 and at least part of the first part 11 of the first support member 10 can be located in the first semi-enclosed accommodating space 32a.

[0115] Exemplarily, the second bending portion 33 of the lubricating member 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. Among them, the second extension portion 332 of the second bending portion 33 can be located on the side of the first support member 10 facing away from the first elastic member 20. The fifth surface 332a of the second extension portion 332 can be fixedly connected to the lower surface of the third portion 13 of the first support member 10 by bonding or the like. The second end 332c of the second extension portion 332 can face the first extension portion 322. The second connecting portion 331 can be arranged on the side of the third portion 13 of the first support member 10 away from the first portion 11. At this time, the main body 31 of the lubricating member 30, the first elastic member 20, the third portion 13 of the first support member 10, and the second extension portion 332 of the lubricating member 30 can be stacked in sequence along the second direction. At this time, part of the first elastic member 20 and at least part of the third portion 13 of the first support member 10 can be located in the second semi-enclosed accommodating space 33a.

[0116] It can be understood that, compared with the two lubricating members respectively arranged 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, the outer edge of the first support member is exposed to the external environment. The lubricating member 30 in this embodiment can have a main body 31 covering the surface of the first elastic member 20 facing away from the first support member 10, and also have a first bending portion 32 bent toward the first part 11 of the first support member 10 and a second bending portion 33 bent toward the third part 13 of the first support member 10. In this way, the lubricating member 30 can not only cover the surface of the first elastic member 20, the surface of part of the first part 11 of the first support member 10, and the surface of part of the third part 13 of the first support member 10 at the same time, but also wrap the outer edges of the first elastic member 20 and the first support member 10, so that the lubricating member 30 can also protect the outer edges of the first elastic member 20 and the first support member 10, and prevent the outer edges of the first elastic member 20 and the first support member 10 from scratching with other parts and generating abnormal noise. At the same time, the thickness of the first support member 10 is relatively thin, and its outer edge is relatively sharp. By arranging the lubricating member 30 to wrap the outer edge of the first support member 10 (in the present embodiment, that is, the edge of the first part 11 of the first support member 10 away from the third part 13 and the edge of the third part 13 away from the first part 11), it can also effectively prevent the edge of the first support member 10 from scratching the assembler during the installation of the first support member 10 with other components, which is beneficial to improve the safety of the assembly process.

[0117] Fig.10 yes Figure 1 A partial structural diagram of an electronic device 1000 is shown. Fig.11a yes Figure 1 The partial cross-sectional structure diagram of a partial structure of the electronic device 1000 in one embodiment is shown cut along AA. Fig.11b yes Figure 2 The partial cross-sectional structure diagram of a partial structure of the electronic device 1000 in one embodiment is shown cut along line BB.

[0118] like Figure 10 to Figure 11b As shown, the second portion 12 of the first support member 10 can be fixedly connected to the flat surface 213a of the main shaft portion 213 of the rotating shaft assembly 210 by welding, bonding, etc. At this time, the second portion 12 of the first support member 10 can be fixedly connected to the main shaft portion 213 of the rotating shaft assembly 210. The length of the first support member 10 can be slightly shorter than the length of the rotating shaft assembly 210.

[0119] When the electronic device 1000 is in an open state, the width of the first support member 10 is a third width L3. The third width L3 may be less than or equal to the first width L1. The third width L3 may also be greater than the second width L2. At this time, the first portion 11 of the first support member 10 and the first extension portion 322 of the first bending portion 32 of the lubricating member 30 may overlap the first connection portion 211 of the rotating shaft assembly 210, and the third portion 13 of the first support member 10 and the second extension portion 332 of the second bending portion 33 of the lubricating member 30 may overlap the second connection portion 212 of the rotating shaft assembly 210. When the electronic device 1000 is in a closed state, the first portion 11 of the first support member 10 and the first extension portion 322 of the first bending portion 32 of the lubricating member 30 may overlap the first connection portion 211 of the rotating shaft assembly 210, and the third portion 13 of the first support member 10 and the second extension portion 332 of the second bending portion 33 of the lubricating member 30 may overlap the second connection portion 212 of the rotating shaft assembly 210. The first end 322c of the first extension 322 of the lubricating member 30 may be located in the gap between the main shaft portion 213 and the first connecting portion 211 of the rotating shaft assembly 210. The second end 332c of the second extension 332 of the lubricating member 30 may be located in the gap between the main shaft portion 213 and the first connecting portion 211 of the rotating shaft assembly 210. In this way, the width of the first support member 10 (i.e., the third width L3) may be smaller than the width of the rotating shaft assembly 210 (i.e., the first width L1). The narrow width of the first support member 10 is conducive to reducing the rebound force when the first support member 10 is bent, thereby improving the opening and closing experience of the electronic device 1000. At the same time, when the electronic device 1000 is in the open state, the width of the first support member 10 can be greater than the distance between the first connection portion 211 and the second connection portion 212 of the hinge assembly 210 (i.e., the second width L2), so that the first support member 10 can cover part of the gap between the main shaft portion 213 of the hinge assembly 210 and the first connection portion 211 and part of the gap between the main shaft portion 213 of the hinge assembly 210 and the second connection portion 212 in the thickness direction of the electronic device 1000, thereby preventing the outer edge of the first support member 10 from interfering with the hinge assembly 210 due to being located at the gap of the hinge assembly 210, thereby affecting the opening and closing of the electronic device 1000. At the same time, the first support member 10 can overlap the first connection portion 211 and the second connection portion 212, which is conducive to providing a relatively flat support environment for the fixed assembly of subsequent components. In some embodiments, when the electronic device 1000 is in a closed state, the first end 322 c of the first extension portion 322 of the lubricating member 30 may also overlap the first connecting portion 211 or the main shaft portion 213 .

[0120] For example, the first portion 11 of the first support member 10 can be overlapped with the first connecting portion 211 of the rotating shaft assembly 210 through the first bending portion 32 of the lubricating member 30, and can move relative to the first connecting portion 211. The third portion 13 of the first support member 10 can be overlapped with the second connecting portion 212 of the rotating shaft assembly 210 through the second bending portion 33 of the lubricating member 30, and can move relative to the second connecting portion 212. In this way, when the electronic device 1000 is bent, the first part 11 of the first support member 10 can move together with the first bending part 32 of the lubricating member 30 relative to the first connecting part 211 of the rotating shaft assembly 210, and the third part 13 of the first support member 10 can move together with the second bending part 33 of the lubricating member 30 relative to the second connecting part 212 of the rotating shaft assembly 210. Since the friction coefficient between the lubricating member 30 and the rotating shaft assembly 210 is smaller than the friction coefficient between the first support member 10 and the rotating shaft assembly 210, it is possible to effectively avoid direct contact between the first support member 10 and the rotating shaft assembly 210 during movement to cause scratches, which is beneficial to reducing 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 main shaft portion 213 by welding. For example, a welding gun can weld the first support member 10 and the flat surface 213a of the rotating shaft assembly 210 together at the surface of the first support member 10 where one or more glue holes 20a are exposed. At this time, the welding point 10a between the first support member 10 and the rotating shaft assembly 210 can be located on the flat surface 213a of the main shaft portion 213. The welding point 10a can be exposed relative to the glue hole 20a. The welding point 10a can be spaced apart from the second through hole 14 of the first support member 10. It should be understood that Fig.10 and Fig.11a The positions of the welding points 10 a are indicated by dashed circles.

[0122] It is understandable that, compared with the first support member 10 being fixedly connected to the main shaft portion 213 of the rotating shaft assembly 210 by bonding, the first support member 10 may be debonded from the rotating shaft assembly 210 during the opening and closing process of the electronic device 1000 or when the electronic device 1000 is in some extreme environments, resulting in the screen 300 being arched and the wiring of the screen 300 being broken. In this embodiment, the first support member 10 may be fixedly connected to the main shaft portion 213 of the rotating shaft assembly 210 by welding, so that the first support member 10 may be more stably fixed to the rotating shaft assembly 210. In this way, even if the electronic device 1000 is opened and closed many times or the electronic device 1000 is in some extreme environments, the first support member 10 can maintain a fixed connection relationship with the rotating shaft assembly 210, thereby effectively avoiding the problem of the screen 300 being arched and the wiring being broken due to the falling off of the first support member 10, which is conducive to improving the overall structural stability of the electronic device 1000 and extending the service life of the electronic device 1000.

[0123] Secondly, compared to stacking and fixing the first support member 10, the first elastic member 20 and the lubricating member 30 in sequence on the rotating shaft assembly 210, in this embodiment, the first support member 10, the first elastic member 20 and the lubricating member 30 are first assembled together to form a whole, and then the whole is fixed on the rotating shaft assembly 210 together. In this way, on the one hand, it can be effectively avoided that the adhesive overflows onto the housing device 200 of the electronic device 1000 during the fixing process of the first elastic member 20 and the fixing process of the lubricating member 30, causing some parts to stick to each other and affecting the opening and closing experience of the electronic device 1000; on the other hand, the first support member 10 and the first elastic member 20 are both flat sheet structures, so that the first elastic member 20 and the lubricating member 30 can be assembled in a relatively flat supporting environment during the bonding and fixing process, and the first support member 10, the first elastic member 20 and the lubricating member 30 are easier to assemble, and it is also beneficial to reduce the bubbles in the adhesive between the first support member 10, the first elastic member 20 and the lubricating member 30, thereby improving the connection stability between the first support member 10, the first elastic member 20 and the lubricating member 30, and effectively avoiding the first elastic member 20 or the lubricating member 30 from debonding and stratification at the bubble due to multiple opening and closing of the electronic device 1000, which is beneficial to improving the overall structural stability of the electronic device 1000 and extending the service life of the electronic device 1000.

[0124] Fig.12 yes Figure 1 A partial structural diagram of an electronic device 1000 is shown. Fig.13 yes Figure 1 The partial cross-sectional structure diagram of a partial structure of the electronic device 1000 in one embodiment is shown cut along AA.

[0125] like Fig.12 and Fig.13 As shown, the first elastic member 20 may be provided with a plurality of first through holes 21. The plurality of first through holes 21 may be arranged at intervals along the length extension direction of the first elastic member 20. The shapes and sizes of the plurality of first through holes 21 may not be exactly the same. The second portion 12 of the first support member 10 may be provided with a plurality of second through holes 14. The plurality of second through holes 14 may be arranged at intervals along the length extension direction of the first support member 10. The shapes and sizes of the plurality of second through holes 14 may not be exactly the same. The second through hole 14 may expose a portion of the flat surface 213a of the main shaft portion 213. Exemplarily, the number of the first through holes 21 may be the same as the number of the second through holes 14. The plurality of first through holes 21 may expose a plurality of second through holes 14 in a one-to-one correspondence and connect the plurality of second through holes 14. At this time, the first through hole 21 may also expose a portion of the flat surface 213a of the main shaft portion 213.

[0126] Exemplarily, the opening size of the second through holes 14 in each group of second through holes 14 and the first through holes 21 may not be larger than the opening size of the first through holes 21. At this time, in the thickness direction of the electronic device 1000, the first through holes 21 and the second through holes 14 may at least partially overlap. In this embodiment, the opening size of the second through holes 14 in each group of second through holes 14 and the first through holes 21 may be smaller than the opening size of the first through holes 21. At this time, the plurality of first through holes 21 may also expose part of the upper surface of the first support member 10 around the plurality of second through holes 14 in a one-to-one correspondence, for example, expose part of the upper surface of the second portion 12 of the first support member 10. In other embodiments, the opening size of the second through holes 14 in each group of second through holes 14 and the first through holes 21 may be equal to the opening size of the first through holes 21. At this time, the plurality of first through holes 21 may only expose part of the flat surface 213a of the main shaft portion 213.

[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 in one-to-one correspondence, and connect the plurality of first through holes 21. At this time, the plurality of third through holes 34 may constitute a plurality of dispensing holes 20a in one-to-one correspondence with the plurality of first through holes 21. Among them, the shape and size of the third through holes 34 and the first through holes 21 in each group of the first through holes 21 and the 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 hole 21. At this time, the plurality of third through holes 34 may also expose the upper surface of the portion of the first support member 10 exposed by the plurality of second through holes 14 and the plurality of first through holes 21 in one-to-one correspondence. That is, the plurality of dispensing holes 20a can expose the upper surface of the first support member 10 exposed by the plurality of second through holes 14 and the plurality of first through holes 21 in a one-to-one correspondence. Figures 6 to 10 The first through hole 21, the second through hole 14 and the third through hole 34 are also shown schematically.

[0128] like Fig.12 and Fig.13 As shown, the first adhesive 40 can be in block shape. The number of the first adhesive 40 can be multiple. The thickness of the multiple first adhesives 40 can be the same. The number of the first adhesive 40 can be the same as the number of the dispensing holes 20a. The multiple first adhesives 40 can be located in the multiple dispensing holes 20a and the multiple second through holes 14 in a one-to-one correspondence. At this time, each first adhesive 40 can be roughly in an inverted "convex" shape. A portion of the first adhesive 40 can be located in the second through hole 14, and connect the flat surface 213a of the shaft assembly 210 and the peripheral side wall of the second through hole 14 (that is, the first support member 10). Another portion of the first adhesive 40 can be located in the dispensing hole 20a, and connect the upper surface of the first support member 10 exposed in the dispensing hole 20a. Exemplarily, the first adhesive 40 can be a hot melt adhesive. The hot melt adhesive can be filled in each adhesive dispensing hole 20a, and before being solidified, can flow into the plurality of second through holes 14 one by one, and after the hot melt adhesive is solidified, a first adhesive 40 in the shape of an inverted "convex" can be formed.

[0129] In some embodiments, the sizes of the second through holes 14 may not be exactly the same. For example, the length of one or more second through holes 14 located in the middle of the plurality of second through holes 14 may be slightly larger than the length of the remaining second through holes 14. The spacing distance between any two adjacent second through holes 14 may not be exactly the same. The length extension direction of the second through holes 14 is the same as the length extension direction of the first support member 10. In this way, by changing the length of each second through hole 14 and the spacing between two adjacent second through holes 14, when the first support member 10 is subsequently fixedly connected to the shaft assembly 210, each second through hole 14 can avoid the uneven structure in the main shaft portion 213 of the shaft assembly 210, thereby facilitating the subsequent installation and fixation of other components (please refer to Figure 4 ).

[0130] In other embodiments, the first elastic member 20 may also be provided with only one first through hole 21, and the lubricating member 30 may also be provided with only one third through hole 34. The first through hole 21 may be a long strip through hole, and exposes all the second through holes 14 and part of the upper surface of the first support member 10 around each second through hole 14. The third through hole 34 may be the same shape and size as the first through hole 21, and exposes the first through hole 21. At this time, the first through hole 21 and the third through hole 34 may together constitute a long strip dispensing hole 20a. The number of the first adhesive 40 may also be one. At this time, the first adhesive 40 may be in a long strip shape, which is adapted to the shape of the dispensing hole 20a. The long strip of the first adhesive 40 may simultaneously fill the long strip dispensing hole 20a and a plurality of second through holes 14.

[0131] In some other embodiments, the number of the first through holes 21 and the number of the third through holes 34 may not be equal. In this case, the relationship between the plurality of first through holes 21 and the plurality of third through holes 34 may be two to one, for example, one third through hole 34 may expose two first through holes 21. Alternatively, the relationship between the plurality of first through holes 21 and the plurality of third through holes 34 may be three to one, one to two, 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 specifically limit this.

[0132] Fig.14 yes Figure 1 A partial structural diagram of an electronic device 1000 is shown. Fig.15a yes Figure 1 The partial cross-sectional structure diagram of a partial structure of the electronic device 1000 in one embodiment is shown cut along AA. Fig.15b yes Figure 2 The partial cross-sectional structure diagram of a partial structure of the electronic device 1000 in one embodiment is shown cut along line BB.

[0133] like Figure 14 to Figure 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 the action of an external force. Of course, under the condition of 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, a stainless steel sheet, etc. This application does not make strict restrictions on this. Among them, the length of the second support member 50 can be slightly shorter than the length of the shaft assembly 210.

[0134] Exemplarily, the second support member 50 may be located above the lubricating member 30. The second support member 50 may be fixedly connected to the first adhesive 40. At this time, the second support member 50 may 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. The second support member 50, except for the fixed connection to the first adhesive 40, may overlap the lubricating member 30 and may move relative to the lubricating member 30. When the electronic device 1000 is in an open state, the width of the second support member 50 is the fourth width L4. The fourth width L4 may be less than or equal to the third width L3. Exemplarily, the fourth width L4 may also be less than or equal to the second width L2. At this time, the second support member 50 has no overlapping portion with the first connecting portion 211 of the rotating shaft assembly 210 in the thickness direction of the electronic device 1000. The second support member 50 has no overlapping portion with the second connecting portion 212 of the rotating shaft assembly 210 in the thickness direction of the electronic device 1000. When the electronic device 1000 is in a closed state, the second support member 50 and the first connection portion 211 of the hinge assembly 210 have no overlap in the thickness direction of the electronic device 1000. The second support member 50 and the second connection portion 212 of the hinge assembly 210 also have no overlap in the thickness direction of the electronic device 1000. In this way, the width of the second support member 50 is narrow, so that the rebound force when the second support member 50 is bent can be effectively reduced, and the opening and closing of the electronic device 1000 is smoother, which is conducive to improving the user experience.

[0135] It can be understood that, in this embodiment, by respectively setting the first through hole 21 on the first elastic member 20, setting the second through hole 14 on the first support member 10, and setting the third through hole 34 on the lubricating member 30, the first adhesive 40 can be located in the above-mentioned through holes and can contact the flat surface 213a of the rotating shaft assembly 210. In this way, on the one hand, the second support member 50 can be directly fixed to the flat surface 213a of the rotating shaft assembly 210 through the first adhesive 40, which is conducive to improving the connection stability of the second support member 50; on the other hand, the first adhesive 40 can use the thickness space of the first support member 10, the first elastic member 20 and the lubricating member 30, so that the thickness of the elastic assembly 100 will not be increased while the second support member 50 is fixed, which is conducive to realizing the thin design of the electronic device 1000. At the same time, the through holes on the first support member 10, the first elastic member 20 and the lubricating member 30 (that is, the second through hole 14, the first through hole 21 and the third through hole 34 in this embodiment) can be used to control the thickness of the first adhesive 40, thereby avoiding the problem that the first adhesive 40 is too thin to ensure the connection stability of the second support member 50, and avoiding the problem that the first adhesive 40 is too thick and causes the screen 300 to be uneven.

[0136] Secondly, in this embodiment, the opening of the second through hole 14 of the first support member 10 may be no larger than the opening of the first through hole 21 of the first elastic member 20. When the opening of the second through hole 14 is equal to the opening of the first through hole 21, the second through hole 14 can also expose part of the main shaft portion 213 exposed by the first through hole 21, so that the first adhesive 40 can realize the fixed connection between the second support member 50 and the rotating shaft assembly 210, which is beneficial to improve 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 part of the upper surface of the first support member 10. In this way, when the second support member 50 is fixed by the first adhesive 40, on the one hand, the opening of the second through hole 14 is relatively small, and the second through hole 14 only exposes a portion of the flat surface 213a of the shaft assembly 210, so that the first adhesive 40 can achieve a fixed connection between the second support member 50 and the shaft assembly 210, while the first adhesive 40 will not overflow from the second through hole 14 to other components of the shaft assembly 210, thereby effectively avoiding the problem of other components adhering to each other due to the overflow of the first adhesive 40; on the other hand, the first through hole 21 The opening is larger than the opening of the second through hole 14, so that the second support member 50 can be directly fixedly connected to the hinge assembly 210 through the first adhesive 40, and can also be fixedly connected to the upper surface of the first support member 10 through the first adhesive 40, so as to increase the fixing area 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 hinge assembly 210, and also improving the connection stability between the second support member 50 and the first support member 10, which is beneficial to improving the overall structural stability of the electronic device 1000.

[0137] In other embodiments, the first support member 10 may not be provided with the second through hole 14. In this case, the first through hole 21 of the first elastic member 20 may only expose a portion of the surface of the first support member 10. The second support member 50 may be fixedly connected to the portion of the surface of the first support member 10 exposed by the first through hole 21 by the first adhesive 40.

[0138] Fig.16a yes Figure 3 The screen 300, the second elastic member 70 and the third adhesive 80 of the electronic device 1000 are shown as a schematic diagram of the exploded structure after being turned upside down. Fig.16b yes Fig.16a The schematic diagram of the assembly structure of the screen 300, the second elastic member 70 and the third adhesive 80 is shown.

[0139] like Fig.16a and Fig.16bAs shown, the screen 300 may include a flexible display screen 301 and a carrier plate 302 for supporting the flexible display screen 301. The carrier plate 302 may be located on the non-display side of the flexible display screen 301 and fixedly connected to the flexible display screen 301 ( Figure 3 The flexible display screen 301 and the carrier plate 302 of the screen 300 are also shown. The flexible display screen 301 can be bent, and the carrier plate 302 can be bent and have a certain structural strength, so that the screen 300 can realize both unfolding and folding actions, and can also have a certain structural strength, thereby having a higher structural reliability.

[0140] For example, the screen 300 may include a first portion 310, a second portion 320, and a third portion 330. The second portion 320 may be connected between the first portion 310 and the third portion 330. When the screen 300 is flattened, the first portion 310, the second portion 320, and the third portion 330 may be arranged in sequence along the first direction. It should be noted that Fig.16a and Fig.16b In the figure, the first part 310, the second part 320 and the third part 330 of the screen 300 are schematically divided by dotted lines. For ease of understanding, the volume of the second part 320 indicated by the dotted line is slightly larger than the actual volume of the second part 320.

[0141] Exemplarily, the portion of the carrier plate 302 located in the second portion 320 may be provided with a plurality of strip holes 302a. The extension directions of the plurality of strip holes 302a may be the same. The length extension direction of the plurality of strip holes 302a may be the same as the length extension direction of the rotating shaft assembly 210. In this way, the plurality of strip holes 302a may effectively reduce the rigidity of the portion of the carrier plate 302 located in the second portion 320. When the electronic device 1000 is bent, the portion of the carrier plate 302 located in the second portion 320 may be better bent, which is conducive to improving the opening and closing experience of the electronic device 1000. In some embodiments, the portion of the carrier plate 302 located in the first portion 310 close to the second portion 320 may also be provided with a plurality of strip holes 302a. The portion of the carrier plate 302 located in the third portion 330 close to the second portion 320 may also be provided with a plurality of strip holes 302a. In this way, the second part 320 of the screen 300 may also be provided with strip holes 302a on both sides, so as to better reduce the rebound force when the second part 320 is bent, which is conducive to improving 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 may also be provided with strip grooves on both sides, and the length extension direction of the strip grooves may be the same as the length extension direction of the hinge assembly 210.

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

[0143] Exemplarily, 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. At this time, the second elastic member 70 and the screen 300 can be respectively located on two sides opposite to each other 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. Among them, the second elastic member 70 and the third adhesive 80 can have the same shape and size. The second elastic member 70 can be roughly rectangular. The width of the second elastic member 70 can be greater than or equal to the width of the second part 320 of the screen 300. At this time, the second elastic member 70 can overlap with the second part 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 part 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 carrier 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 carrier 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 carrier plate 302 with the strip holes 302a (that is, the portion of the carrier plate 302 located at the second portion 320 in this embodiment), thereby effectively preventing the electronic device 1000 from falling in the unfolded state, causing the portion of the carrier plate 302 with the strip holes 302a to bulge, and causing the second portion 320 of the screen 300 to bulge, which is beneficial to improving the overall structural strength of the screen 300 and extending the service life of the screen 300.

[0144] Fig.17 yes Figure 1 The partial cross-sectional structure diagram of a partial structure of the electronic device 1000 in one embodiment is shown cut along AA.

[0145] like Fig.17As shown, the second adhesive 60 may be roughly in the shape of a long strip. The second adhesive 60 may be located above the second support member 50 and fixedly connected to the second support member 50. The second adhesive 60 may be an adhesive with a certain deformation ability such as a hot melt adhesive. Exemplarily, the projection of the second adhesive 60 in the thickness direction of the electronic device 1000 may at least partially overlap with the flat surface 213a of the hinge assembly 210.

[0146] The width of the second adhesive 60 may be smaller than the width of the second supporting member 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 hinge assembly 210, and the width of the second adhesive 60 is narrow, so that the rebound force of the second adhesive 60 when bent can be effectively reduced, which is conducive 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 shaft assembly 210. Equal may be completely equal or approximately equal, for example, the width of the second adhesive 60 may be slightly larger or smaller than the width of the flat surface 213a.

[0149] Fig.18a yes Figure 1 The illustrated diagram is a partial cross-sectional structural diagram of an electronic device 1000 in one embodiment cut along AA. Fig.18b yes Figure 1 The partial cross-sectional structure diagram of the electronic device 1000 shown in FIG. 1 is a partial cross-sectional structure diagram of an embodiment of the electronic device 1000 cut along the AA line. Fig.18b relatively Fig.18a The screen 300 is hidden.

[0150] like Figure 17 to Figure 18b As shown, the first portion 310 of the screen 300 may be located above the first housing 220 and fixedly connected to the first adhesive 240. The third portion 330 of the screen 300 may be located above the second housing 230 and fixedly connected to the second adhesive 250. Figure 4 The first adhesive backing 240 and the second adhesive backing 250 are also illustrated from another perspective. At this time, the flexible display screen 301 can be located on the side of the carrier plate 302 facing away from the hinge assembly 210. The surface of the second elastic member 70 facing away from the third adhesive 80 can be fixedly connected to the second adhesive 60. When the electronic device 1000 is in the open state, the second portion 320 of the screen 300, the elastic assembly 100 and the hinge 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 an open state, the first portion 101, the third portion 103, and the second portion 102 may be arranged in sequence along the first direction. The first portion 101 of the elastic component 100 may overlap the first connecting portion 211 of the hinge assembly 210. The second portion 102 of the elastic component 100 may overlap the second connecting portion 212 of the hinge assembly 210. The third portion 103 of the elastic component 100 may be fixedly connected to the main shaft portion 213 of the hinge assembly 210. It should be understood that Fig.18b The first part 101, the second part 102 and the third part 103 of the elastic component 100 are schematically divided by dotted lines.

[0152] It can be understood that, compared with stacking and fixing the second elastic member 70, the third adhesive 80 and the screen 300 on the second adhesive 60 in sequence, in this embodiment, the second elastic member 70, the third adhesive 80 and the screen 300 are first assembled together to form the screen assembly 400, and then the entire screen assembly 400 is fixed together on the second adhesive 60. In this way, the screen 300 can provide a relatively flat supporting environment during the assembly process of the second elastic member 70 and the third adhesive 80, so that the second elastic member 70 and the third adhesive 80 are easier to assemble on the screen 300, and it is also helpful to reduce the bubbles in the third adhesive 80, so that the connection stability between the second elastic member 70, the third adhesive 80 and the screen 300 can be effectively improved, and the problem of debonding and stratification between the second elastic member 70 and the third adhesive 80 or the screen 300 and the third adhesive 80 at the bubble due to multiple opening and closing of the electronic device 1000 can be effectively avoided, which is beneficial to improve the overall structural stability of the electronic device 1000 and extend the service life of the electronic device 1000. In other words, the screen assembly 400 in this embodiment may include at least one elastic member.

[0153] In other embodiments, the second support member 50 and the second adhesive 60 may be first assembled with the screen 300, the second elastic member 70 and the third adhesive 80 to form a screen assembly 400. Then, the entire screen assembly 400 is fixed together with 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 again Fig.18a and Fig.18bWhen the electronic device 1000 is in the open state, the screen 300 and the elastic component 100 can be relatively flattened under the drive of the housing device 200. The first support member 10, the first elastic member 20, the second support member 50 and the second elastic member 70 can all be located above the flat surface 213a of the hinge assembly 210, and arranged in sequence along the direction from the housing device 200 to the screen 300.

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

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

[0157] Fig.19a yes Figure 2 The partial cross-sectional structure diagram of a partial structure of the electronic device 1000 in one embodiment is shown cut along line BB. Fig.19b yes Figure 2 The illustrated diagram is a partial cross-sectional structural diagram of an electronic device 1000 in one embodiment cut along line BB.

[0158] like Fig.19a and Fig.19bAs shown, when the electronic device 1000 is in a closed state, the screen 300 and the elastic component 100 can be folded relative to each other under the drive of the housing device 200. The second portion 320 of the screen 300 can be relatively 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. Among them, the first portion 101 of the elastic component 100 can overlap the first connecting portion 211 of the rotating shaft component 210. The second portion 102 of the elastic component 100 can overlap the second connecting portion 212 of the rotating shaft component 210.

[0159] Among them, the second adhesive 60 of the elastic component 100 can be deformed to a certain extent under the pressure of the screen 300, and the left and right sides of the second adhesive 60 will be compressed in the direction close to the hinge assembly 210, so that the surface of the second adhesive 60 facing away from the hinge assembly 210 can be bent into an arc shape, thereby better fitting the bent screen 300, so that the elastic component 100 can provide 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 in the direction close to the hinge assembly 210, so that the surface of the first adhesive 40 facing away from the hinge assembly 210 can be bent into an arc shape, thereby better fitting the bent screen 300.

[0160] It is understandable that, compared with the traditional electronic device that sacrifices the thickness of the screen to improve the overall structural reliability of the screen, resulting in a thicker overall thickness of the electronic device and a larger rebound force when bent, the electronic device 1000 of this embodiment is provided with an elastic component 100 between the screen 300 and the main shaft portion 213 of the rotating shaft assembly 210. Among them, the elastic component 100 may include a supporting portion and an elastic portion. The material of the supporting portion may be a rigid material, and the material of the elastic portion may be an elastic material or a non-Newtonian fluid material. When the electronic device 1000 is in a closed state, the rotating shaft assembly 210 may be located on the inner side of the screen 300, and the elastic component 100 may be fixed between the second portion 320 of the screen 300 and the main shaft portion 213 of the rotating shaft assembly 210. When the electronic device 1000 is in an open state, the screen 300, the elastic component 100 and the rotating shaft assembly 210 may be stacked along the thickness direction of the electronic device 1000. In this way, when the electronic device 1000 falls, especially when the electronic device 1000 falls in a closed state, the supporting part of the elastic component 100 can better absorb the impact force and / or squeezing force of the hinge component 210 on the screen 300, reduce the impact force on the screen 300, and provide good rigid support for the screen 300. The elastic part in the elastic component 100 can play a good elastic role in the impact force and / or squeezing force applied to the screen 300, and the elastic part can also absorb and disperse the impact force and / or squeezing force on the screen 300. The elastic component 100 can effectively absorb the impact force on the second part 320 of the screen 300 caused by falling, avoid the second part 320 of the screen 300 from having a strong collision with the hinge component 210, and cause the screen 300 to have broken bright spots and black spots, which is conducive to improving the structural reliability of the screen 300 and extending the service life of the screen 300. In other words, the screen 300 in this embodiment does not need to sacrifice its own thickness. The elastic component 100 located between the screen 300 and the hinge component 210 can effectively improve the reliability of the screen 300 when it falls. At the same time, the overall thickness of the screen 300 is relatively thin, which can effectively reduce the rebound force when the electronic device 1000 is bent, which is beneficial to improving the user's opening and closing experience.

[0161] Secondly, the supporting part of the elastic component 100 may include at least one supporting member (also referred to as the first supporting member 10 in this embodiment). The elastic part of the elastic component 100 may include at least one elastic member (also referred to as the first elastic member 20 in this embodiment). The material of the first supporting member 10 may be a rigid material, and the material of the first elastic member 20 may be an elastic material or a non-Newtonian fluid material. In this way, when the electronic device 1000 falls and the second part 320 of the screen 300 is impacted, the first supporting member 10 can better absorb the impact force and / or squeezing force of the rotating shaft assembly 210 on the second part 320 of the screen 300, reduce the impact force on the screen 300, and provide good rigid support for the screen 300. The first elastic member 20 can play a good elastic role in the impact force and / or squeezing force applied to the screen 300, and can absorb and disperse the impact force and / or squeezing force on the screen 300. In other words, the elastic component 100 of this embodiment includes a first support member 10 and a first elastic member 20. The first support member 10 and the first elastic member 20 respectively provide good rigid protection and elastic protection for the screen 300. The entire elastic component 100 has strong impact resistance and extrusion resistance, so that the elastic component 100 can better protect the screen 300, improve the falling reliability of the screen 300, and help to extend the service life of the screen 300.

[0162] In addition, the elastic component 100 in this embodiment may further include a second support member 50 and a second elastic member 70. The first support member 10, the first elastic member 20, the second support member 50 and the second elastic member 70 may be arranged in sequence along the direction of the rotating shaft assembly 210 toward the screen 300, and may be stacked. The first support member 10 and the second support member 50 may together constitute the support portion of the elastic component 100. The first elastic member 20 and the second elastic member 70 may together constitute the elastic portion of the elastic component 100. In this way, 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) in the elastic component 100, the entire elastic component 100 may form a structure similar to a bulletproof vest, which is beneficial to improving the impact resistance and extrusion resistance of the elastic component 100. Compared with directly increasing the thickness of the first support member 10 and the thickness of the first elastic member 20 to improve the impact resistance and extrusion resistance of the elastic component 100, the elastic component 100 in this embodiment has better impact resistance and extrusion resistance under the same thickness conditions. Under the same performance conditions, the thickness of each support member and each elastic member of the elastic component 100 in this embodiment is thinner, and multiple support members and multiple elastic members are fixed to each other through a glue layer. In this way, when the electronic device 1000 is bent, a certain displacement can occur between the adjacent support members and the elastic members, thereby greatly reducing the rebound force of the entire elastic component 100 when it is bent. In other words, under certain performance conditions, the thickness of the elastic component 100 in this embodiment can be thinner, which is conducive to realizing the thin design of the electronic device 1000. At the same time, the total thickness of the elastic part 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 part can be less than or equal to the total thickness of the elastic part. In this way, the elastic component 100 can have good impact resistance and extrusion resistance while having a relatively thin overall thickness, which is conducive to realizing a thin design of the electronic device 1000 .

[0163] In addition, 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, and the first support member 10, the first elastic member 20, the second support member 50 and the second elastic member 70 can be arranged in sequence along the direction of the rotating shaft assembly 210 toward the screen 300, and are stacked. In this way, compared with the support member being arranged adjacent to the screen 300, the support member has a larger rebound force when being bent, which easily causes the screen 300 to be damaged when being bent. In this embodiment, the elastic member (i.e., the second elastic member 70 in this embodiment) can be arranged adjacent to the screen 300, and the elastic member has a smaller rebound force when being bent, thereby effectively reducing the probability of the screen 300 being damaged when being bent, which is beneficial to prolonging the service life of the electronic device 1000.

[0164] In addition, when the electronic device 1000 is in the open state, at least part of the elastic component 100 in the present embodiment can be located in the first mounting groove 221. The sum of the thickness of the elastic component 100 itself and the thickness of the shaft component 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 while not 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, so as to provide a relatively flat supporting environment for the screen 300, improve the display effect of the screen 300, and improve the user experience.

[0165] In some embodiments, the elastic component 100 may include a first support member 10, a first elastic member 20, a second support member 50, and a second elastic member 70, and the first elastic member 20, the first support member 10, the second elastic member 70, and the second support member 50 may be arranged in sequence along the direction of the rotating shaft assembly 210 toward the screen 300, and may be stacked. In this way, compared with the elastic member being arranged adjacent to the screen 300, the elastic member has limited ability to disperse and / or absorb impact force when the electronic device 1000 falls, and the screen 300 may be easily damaged when it falls. In this embodiment, the support member (i.e., the second support member 50 in this embodiment) may be arranged adjacent to the screen 300. When the electronic device 1000 falls, the support member can better absorb the impact force, and can provide good rigid support for the screen 300, thereby effectively reducing the probability of damage to the screen 300 when it falls, which is conducive to extending 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 constitute a part of the support portion of the elastic component 100. The third support member may be fixed between the third adhesive glue 80 and the screen 300. Alternatively, the elastic component 100 may further include a third elastic member. The third elastic member may constitute a 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 shaft assembly 210. Alternatively, the elastic component 100 may also include a third support member and a third elastic member at the same time. The third support member and the third elastic member may be fixed together between the third adhesive glue 80 and the screen 300. At this time, 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 in sequence along the thickness direction of the electronic device 1000, and are stacked. The present application does not specifically limit the number of support members in the support portion of the elastic component 100 and the number of elastic members in the elastic portion.

[0167] In some other embodiments, the elastic component 100 may not include the second support member 50 , the second elastic member 70 , the second adhesive 60 and the third adhesive 80 , and the first adhesive 40 may directly connect the first support member 10 and the screen 300 .

[0168] Fig. 20 yes Figure 6 The structure schematic diagram of the first supporting member 10 in another embodiment is shown.

[0169] like Fig. 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 substantially the same, and the same parts are not repeated. The difference is that the first support member 10 may also be provided with at least one fourth through hole 15. The fourth through hole 15 may be spaced apart from the solder joint 10a. In the present embodiment, the number of the fourth through holes 15 may be two. The solder joint 10a may be located between 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 extension direction of the fourth through hole 15 may intersect with the extension direction of the first support member 10, for example, the extension direction of the fourth through hole 15 may also be perpendicular to the extension direction of the first support member 10.

[0170] It is understandable that when the electronic device 1000 falls, the screen 300 will slip under the action of inertia, and at the same time, a pulling force will be generated on the elastic component 100. When the pulling force acts on the first support member 10, it is easy to cause the solder joint 10a between the first support member 10 and the rotating shaft assembly 210 to be desoldered due to the pulling force from the screen 300, affecting the contact between the first support member 10 and the main shaft part 213 of the rotating shaft assembly 210, thereby generating 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, which is spaced apart from the solder joint 10a. In this way, the fourth through hole 15 can block the pulling force from being transmitted to the solder joint 10a, thereby effectively preventing the first support member 10 from being desoldered, which is conducive to ensuring the connection reliability between the first support member 10 and the rotating shaft assembly 210, and reducing the impact on the antenna performance of the whole device.

[0171] Fig.21 yes Figure 6 The structure diagram of the first supporting member 10 in another embodiment is shown.

[0172] like Fig.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 substantially the same, and the same parts are not repeated. The differences between the two will be described below. Exemplarily, at least one corner of the first support member 10 can also be trimmed to form at least one escape space 10c. The escape space 10c can be used to avoid the antenna in the electronic device 1000. In this embodiment, the first support member 10 can be roughly in the shape of an elongated strip and have four corners. The four corners can all be trimmed to form four escape spaces 10c.

[0173] It can be understood that in this embodiment, the corners of the first support member 10 are trimmed to form an avoidance space 10c, so that the edge of the first support member 10 can be away from the antenna inside the electronic device 1000, thereby reducing the radio frequency interference of the first support member 10 on the antenna inside the electronic device 1000 and reducing the impact of the first support member 10 on the antenna performance of the entire device.

[0174] In some embodiments, the shape and size of the first elastic member 20 can be the same as the first support member 10. The shape and size of the lubricating member 30 can also be the same as the first support member 10. In other words, the first elastic member 20 and the lubricating member 30 can both perform trimming on each corner. In this way, the first support member 10, the first elastic member 20 and the lubricating member 30 can be assembled together and trimmed together, which is beneficial to save the preparation process and reduce dimensional errors. At the same time, the shapes and sizes of the first support member 10, the first elastic member 20 and the lubricating member 30 are consistent, so that the step difference area between the first support member 10, the first elastic member 20 and the lubricating member 30 can be effectively avoided, which is beneficial to provide a flat support environment for the screen 300.

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

[0176] like Fig. 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 roughly the same, and the same parts are not repeated. The following mainly introduces the differences between the two. The first support member 10 in this embodiment can also be provided with a plurality of first holes 16 and a second hole 17. The number of the first holes 16 can be the same as the number of the second holes 17. The plurality of first holes 16 can be located in the first part 11 of the first support member 10. The plurality of first holes 16 can be arranged at intervals along the length direction of the first support member 10. The plurality of second holes 17 can be located in the third part 13 of the first support member 10. The plurality of second holes 17 can be arranged at intervals along the length extension direction of the first support member 10. The first hole 16 and the second hole 17 can both be long strip holes. The extension direction of the first hole 16 and the second hole 17 can both intersect with the length extension direction of the first support member 10. In this embodiment, the extension direction of the plurality of first holes 16 and the plurality of second holes 17 can be perpendicular to the length extension direction of the first support member 10.

[0177] It can be understood that in this embodiment, by providing a plurality of first holes 16 whose extension directions intersect with the length extension direction of the first support member 10 on the first part 11 of the first support member 10, and providing a plurality of second holes 17 whose extension directions intersect with the length extension direction of the first support member 10 on the third part 13 of the first support member 10, the rebound force when the first support member 10 is bent can be effectively reduced, which is beneficial to improving the opening and closing experience of the electronic device 1000.

[0178] Fig.23 yes Figure 8 The structure diagram of the first elastic member 20 in another embodiment is shown.

[0179] like Fig.23 As shown, the structure of the first elastic member 20 in this embodiment is similar to Figure 8 The structures of the first elastic member 20 shown are roughly the same, and the same parts will not be repeated. The following mainly introduces the differences between the two. The first elastic member 20 in this embodiment may include a first end 22 and a second end 23 that are arranged opposite to each other. The first end 22 and the second end 23 may be provided with a plurality of grooves 24. Taking the first end 22 as an example, the plurality of grooves 24 may be arranged at intervals. The opening of the groove 24 may be arranged facing away from the second end 23. At this time, the first end 22 may be roughly serrated or wavy. The arrangement of the second end 23 is the same as that of the first end 22, and will not be repeated here.

[0180] It can be understood that in this embodiment, one or more grooves 24 are provided at the first end 22 and the second end 23 of the first elastic member 20, so that a release space can be provided for the first elastic member 20 to bulge at its ends (i.e., the first end 22 and the second end 23) when the electronic device 1000 falls in the open state. This can effectively avoid the problem that the first elastic member 20 bulges at the edges of its ends when the electronic device 1000 falls in the open state, causing the screen 300 to bulge, resulting in the wiring of the screen 300 being broken and causing the screen 300 to fail. This is beneficial to extending the service life of the screen 300 and improving user experience.

[0181] In other embodiments, Fig.24 As shown, the first end portion 22 may also be provided with only one arc-shaped groove 24. In this case, the first end portion 22 may be substantially arc-shaped. The present application does not specifically limit the shape and number of the groove 24.

[0182] It should be noted that, in the absence of conflict, the features in the embodiments of the present application can be combined with each other, and any combination of features in different embodiments is also within the protection scope of the present application. That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0183] It should be noted that all the above drawings are illustrative illustrations of the present application and do not represent the actual size of the product. Moreover, the size ratio relationship between the components in the drawings is not intended to limit the actual product of the present application.

[0184] The above are only some implementation methods of the present application, and the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by any person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
