Description

Technical Field

[0001] The present application relates to the technical field of electronic devices, and particularly relates to a protection mechanism for a folding screen and a foldable electronic device. Background Art

[0002] Currently, with the increasing development of electronic device technology, users have an increasing demand for electronic devices with large sizes and easy portability. Therefore, electronic devices with foldable displays (i.e., folding screens), such as folding mobile phones, have received extensive attention. Among them, the folding screen can be unfolded during use to provide a larger display area, and can be switched to the folded state when not in use, which is convenient for users to carry.

[0003] For an electronic device with a foldable display, during the folding process of the folding screen, the layers inside the folding screen will be stratified, resulting in an uneven surface of the folding screen, thereby affecting the user experience.

[0004] Therefore, there is an urgent need for a protection mechanism for a folding screen that can solve the problem of stratification of the internal layers during the folding process of the folding screen. Summary of the Invention

[0005] The present application provides a protection mechanism for a folding screen and a foldable electronic device. When the protection mechanism is used in a foldable electronic device, it can solve the problem of stratification of the internal layers during the folding process of the foldable electronic device.

[0006] In a first aspect, a protection mechanism for a folding screen is provided. The protection mechanism includes: a driving mechanism and at least two folding components. Each folding component includes a sliding member and a housing.

[0007] The at least two folding components are connected by the driving mechanism. A first gear set is provided on the side of the housing facing the driving mechanism, and the first gear set is located between the housing and the driving mechanism. A sliding area is provided on the side of the housing facing the sliding member, and a second rack is provided in the sliding area.

[0008] A slider is provided on the side of the sliding member facing the housing. The slider realizes the sliding connection between the sliding member and the housing by moving in the sliding area, and the second rack is fixed to the slider.

[0009] The driving mechanism includes a first component. The first end of the first component is fixedly connected to the housing, and the first end slides relative to the second end of the first component. The second end includes a first rack. During the folding process of the at least two folding components, the first rack drives the second rack to move away from the driving mechanism after deceleration through the first gear set, so that the sliding member moves away from the driving mechanism.

[0010] In the above technical solution, a sliding member is provided on one side of the folding screen facing the housing, a sliding area is provided on one side of the housing facing the sliding member, and a slider is provided on the sliding member, and the slider is used to move in the sliding area. During the folding process of at least two folding components, the first rack of the driving mechanism drives the second rack to move away from the driving mechanism after being decelerated by the first gear set. Further, the second rack moving away from the driving mechanism drives the slider on the sliding member to move away from the driving mechanism.

[0011] When the above protection mechanism is applied to a foldable electronic device, during the folding process of the foldable electronic device, since the slider on the sliding member moves away from the driving mechanism in the sliding area, and at the same time, the movement of the sliding member will pull the folding screen of the foldable electronic device to also move away from the driving mechanism, thus the problem of delamination of each layer inside the foldable electronic device during the folding process can be solved.

[0012] Combined with the first aspect, in a possible implementation manner, the second rack is further used to limit the displacement of the sliding member moving in the direction perpendicular to the housing.

[0013] In the above technical solution, the displacement size of the slider on the sliding member in the sliding area of the housing can be controlled by the first rack, the first gear set and the second rack.

[0014] Combined with the first aspect, in a possible implementation manner, the slider and the sliding member are of an integral structure.

[0015] Combined with the first aspect, in a possible implementation manner,

[0016] the number of the first gear sets is the same as the number of the first components,

[0017] When the driving mechanism includes 4 of the first components, 2 of the first gear sets are provided on each side of the housing facing the driving mechanism.

[0018] Combined with the first aspect, in a possible implementation manner, the fixed connection includes adhesive fixed connection and screw fixed connection.

[0019] In one example, the slider and the sliding member may be fixedly connected by an adhesive, and the first end and the housing may be fixedly connected by a screw.

[0020] In the embodiments of the present application, the adhesive is not specifically limited. For example, the adhesive may be an optically clear adhesive OCA. For example, the adhesive may be a back glue or the like.

[0021] In a second aspect, a foldable electronic device is provided, and the electronic device includes:

[0022] Foldable flexible display screen;

[0023] The protection mechanism of the folding screen as described in the first aspect above, the flexible display screen covers the protection mechanism, and the protection mechanism is used to support the flexible display screen;

[0024] Wherein, the protection mechanism includes a driving mechanism. During the folding process of the electronic device, the driving mechanism drives the flexible display screen to move in a direction away from the bending area of the flexible display screen.

[0025] In the above technical solution, a sliding member is provided on the side of the flexible display screen facing the housing, a sliding area is provided on the side of the housing facing the sliding member, and a slider is provided on the sliding member, and the slider is used to move in the sliding area. When the flexible display screen is in the folded state, the first rack of the driving mechanism drives the second rack to move in a direction away from the driving mechanism after being decelerated by the first gear set. Further, the second rack moving in the direction away from the driving mechanism drives the slider on the sliding member to move in a direction away from the driving mechanism. In the embodiment of the present application, during the folding process of the flexible display screen, since the slider on the sliding member moves in the sliding area in a direction away from the driving mechanism, and at the same time the movement of the sliding member will pull the flexible display screen to also move in a direction away from the driving mechanism, the problem of delamination of each layer inside the foldable electronic device during the folding process can be solved.

[0026] Combined with the second aspect, in a possible implementation manner,

[0027] The protection mechanism includes a sliding member;

[0028] The flexible display screen includes a flexible cover plate and a display module, and the flexible cover plate is fixedly connected to the display module;

[0029] The display module covers the sliding member. Combined with the second aspect, in a possible implementation manner, the size of the flexible cover plate is larger than the size of the display module.

[0030] Combined with the second aspect, in a possible implementation manner, the display module includes a polarizer, a touch layer, a light-emitting layer, and a backplane. Description of the Drawings

[0037] Next, the technical solutions in the present application will be described with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0038] The following details the implementation manners of the present application. The examples of the implementation manners are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The implementation manners described below with reference to the drawings are exemplary and are only used to explain the present application, and should not be construed as a limitation to the present application.

[0039] Hereinafter, terms such as "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features.

[0040] It should also be noted that in the embodiments of the present application, the same reference numeral represents the same component or the same part. For the same parts in the embodiments of the present application, only one of the parts or components may be marked with a reference numeral in the figure. It should be understood that the reference numeral also applies to other identical parts or components.

[0041] In the description of the present application, it should be noted that unless otherwise clearly defined and limited, the terms "mounted", "connected" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection, an electrical connection or a communication with each other; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0042] In the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "side", "inner", "outer", etc. is based on the installed orientation or positional relationship, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0043] In the description of the present application, it should be noted that the term "and / or" is merely an association relationship describing associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0044] The following introduces the related technologies provided by the embodiments of the present application:

[0045] In the prior art, the following methods are usually adopted to design a folding screen structure: on the one hand, the folding screen cover plate is bonded to the housing through a back glue, and the folding screen back plate is not bonded to the housing. However, this method causes serious arching of the folding screen and causes serious damage to the device. On the other hand, both the folding screen cover plate and the folding screen back plate are bonded to the housing. However, this method causes the folding screen to be unable to have a stepped layer and is prone to peeling. The above methods cannot solve the problem of delamination of each layer inside the folding screen during the folding process of the folding screen.

[0046] The embodiments of the present application provide a protection mechanism for a folding screen and a foldable electronic device. Applying this protection mechanism to a foldable electronic device can solve the problem of delamination of each layer inside the foldable electronic device during the folding process.

[0047] The above foldable electronic device can be any device with communication and / or storage functions, such as smart devices like mobile phones, tablet computers, watches, e-readers, laptop computers, vehicle-mounted devices, network TVs, wearable devices, etc.

[0048] Figure 1 It is an exploded structural schematic diagram of the foldable electronic device 1000 provided by the embodiments of the present application.

[0049] As Figure 1 shown, the foldable electronic device 1000 includes a foldable flexible display screen 100 (i.e., an example of a foldable flexible display screen) and a protection mechanism for the folding screen. The flexible display screen 100 covers the protection mechanism, and the protection mechanism is used to support the flexible display screen 100.

[0050] Among them, the flexible display screen 100 may include a flexible cover plate 10 and a display module 20.

[0051] The flexible cover plate 10 and the display module 20 are fixedly connected, and the flexible cover plate 10 covers the display module 20. Specifically, the flexible cover plate 10 and the display module 20 can be fixedly connected by an adhesive. Among them, the size of the flexible cover plate 10 can be slightly larger than the size of the display module 20, so as to ensure the covering effect and enable the flexible cover plate 10 to be fixedly connected to the first housing 40 and the second housing 60.

[0052] The above-mentioned adhesive can be an optically clear adhesive (OCA). The optically clear adhesive is a double-sided bonding tape without a matrix material, and has the characteristics of colorless transparency, high light transmittance (total light transmittance > 99%), high adhesion, high temperature resistance, ultraviolet resistance, etc., and has a controlled thickness, can provide a uniform spacing, and will not cause yellowing, peeling and deterioration problems after long-term use. For example, the optically clear adhesive can be at least one of fir gum, methanol gum, unsaturated polyester and styrene monomer gum, epoxy resin optically clear adhesive, silicone resin gum, acrylic ester photosensitive gum, etc.

[0053] The flexible cover plate 10 can be a transparent flexible glass cover plate or a transparent flexible plastic cover plate, so that the display module 20 can display through the flexible cover plate 10. In addition, the flexible cover plate 10 can also be made of other materials. For example, the flexible cover plate 10 can also be made of a composite material of flexible glass and flexible plastic.

[0054] In the embodiments of the present application, the specific structure of the display module 20 is not limited.

[0055] In some embodiments, the display module 20 may include: a polarizer, a touch layer, a light-emitting layer, and a backplane. The display module 20 can adopt any one of a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), etc. The embodiments of the present application do not limit this.

[0056] In other embodiments, the display module 20 may further include other components in addition to the polarizer, the touch layer, the light-emitting layer, and the backplane.

[0057] Among them, the protection mechanism of the folding screen includes: a driving mechanism 30 (that is, an example of a driving mechanism) and at least two folding components, and each folding component includes a sliding member and a housing. Among them, the driving mechanism 30 is also called a hinge mechanism or a rotating mechanism.

[0058] As Figure 1 shown, the first housing 40 and the first sliding member 50 may be referred to as the first folding component (i.e., an example of at least two folding components), the second housing 60 and the second sliding member 70 may be referred to as the second folding component (i.e., another example of at least two folding components), and the first folding component and the second folding component are connected by the drive mechanism 30. Among them, the first housing 40 is also referred to as the first support member 40. The second housing 60 is also referred to as the second support member 60. It can be understood that during the folding state of the electronic device 1000, the bent portion of the electronic device 1000 may be referred to as the folding area.

[0059] In the embodiment of the present application, the first folding component and the second folding component are connected by the drive mechanism 30. In each folding component:

[0060] A first gear set is provided on the side of the housing facing the drive mechanism, and the first gear set is located between the housing and the drive mechanism. A sliding area is provided on the side of the housing facing the sliding member, and a second rack is provided in the sliding area;

[0061] A slider is provided on the side of the sliding member facing the housing. The slider realizes the sliding connection between the sliding member and the housing by moving in the sliding area, and the second rack is fixed to the slider.

[0062] Among them, the drive mechanism includes a first component. The first end of the first component is fixedly connected to the housing, the first end slides relative to the second end of the first component, the second end includes a first rack, and during the folding process of at least two folding components, the first rack drives the second rack to move away from the drive mechanism after deceleration by the first gear set, so that the sliding mechanism moves away from the drive mechanism.

[0063] In one example, the slider and the sliding member may be fixedly connected by an adhesive, and the first end and the housing may be fixedly connected by a screw.

[0064] In some embodiments, the second rack is further used to limit the displacement of the sliding member in the direction perpendicular to the housing.

[0065] In some embodiments, the number of the first gear sets is the same as the number of the first components. When the drive mechanism includes 4 first components, 2 first gear sets are provided on the side of each housing facing the drive mechanism.

[0066] As Figure 1As shown, there are 4 first components provided on the driving mechanism 30, and these 4 first components are symmetrically arranged on the driving mechanism 30. Among them, 2 first components are arranged in the direction towards the first housing 40, and 2 first components are also arranged in the direction towards the second housing 60. Based on this, 2 first gear sets are provided on the side of the first housing 40 facing the driving mechanism 30, and 2 first gear sets are also provided on the side of the second housing 60 facing the driving mechanism 30. And each first gear set is located between the corresponding housing and the driving mechanism 30.

[0067] In the embodiment of the present application, the flexible display screen 100 covers the protection mechanism. It can be understood that the display module 20 covers the sliding member. Among them, the sliding member and the display module 20 can be fixedly connected by adhesive bonding, and the sliding member can be used to reinforce the display module 20. Specifically, the first sliding member 50 (i.e., an example of the sliding member) and the second sliding member 70 (i.e., an example of the sliding member) can be fixedly bonded to the display module 20 by an adhesive (such as OCA adhesive).

[0068] Optionally, in some embodiments, in order to increase the flatness of the flexible display screen 100, the first sliding member 50 and the second sliding member 70 can also be set to have a structure including a steel sheet, a copper sheet or a hardened layer.

[0069] Next, Figure 2 introduce the sliding member provided by the embodiment of the present application.

[0070] As Figure 2 shown, the first sliding member 50 is fixedly connected to the first housing 40, and the first sliding member 50 is located on the side of the foldable flexible display screen 100 (i.e., an example of the foldable flexible display screen) facing the first housing 40. Among them, the first sliding member 50 can be fixedly connected to the first housing 40 by back glue. A slider 81 is provided on the side of the first sliding member 50 facing the first housing 40, and the second rack is fixed to the slider 81. The slider 81 is used to move in the sliding area 82. Among them, the slider 81 can be fixed to the side of the first sliding member 50 facing the first housing 40 by screws. The second rack is also used to limit the displacement of the sliding member in the direction perpendicular to the housing.

[0071] Optionally, in some embodiments, the first sliding member 50 and the slider 81 are an integral structure.

[0072] It can be understood that the setting of the second housing 60 and the second sliding member 70 is the same as the setting of the above-mentioned first housing 40 and the first sliding member 50, and will not be elaborated here in detail.

[0073] It should be understood that Figure 2This is only for illustration and does not impose any limitation on the sliding member provided by the embodiments of the present application. For example, in some embodiments, when a rack is provided on the slider of the first sliding member 50 described above, the second rack may not be provided in the sliding area 82.

[0074] Next, in combination with Figure 3 the drive mechanism provided by the embodiments of the present application will be introduced.

[0075] Figure 3 is a schematic structural diagram of the drive mechanism 30 provided by the embodiments of the present application. As Figure 3 shown, the drive mechanism 30 includes 4 first components, and these 4 first components in the drive mechanism 30 are symmetrically arranged respectively.

[0076] Each first component includes a first end and a second end. The first end is fixedly connected to the housing, the first end slides relative to the second end of the first component, the second end includes a first rack, and during the folding process of at least two folding components, the first rack drives the second rack to move away from the drive mechanism through a first gear set, so that the sliding member moves away from the drive mechanism (see Figure 3 the direction indicated by the horizontal arrow in). It should be understood that Figure 3 this is only for illustration and does not impose any limitation on the drive mechanism 30 provided by the embodiments of the present application.

[0077] Figure 4 is a schematic layer structure diagram of the foldable electronic device 1000 provided by the embodiments of the present application in the unfolded state.

[0078] As Figure 4 shown, the foldable electronic device 1000 includes: a flexible cover plate 10, a display module 20, a drive mechanism 30, a first housing 40 (i.e., an example of the housing), a second housing 60 (i.e., an example of the housing), a first sliding member 50 (i.e., an example of the sliding member), a second sliding member 70 (i.e., an example of the sliding member), a first slider 81 (i.e., an example of the slider), a second slider 91 (i.e., an example of the slider), a first sliding area 82 (i.e., an example of the sliding area), and a second sliding area 92 (i.e., an example of the sliding area). Among them, the first housing 40 and the first sliding member 50 can be referred to as the first folding component (i.e., an example of at least two folding components), the second housing 60 and the second sliding member 70 can be referred to as the second folding component (i.e., another example of at least two folding components), and the first folding component and the second folding component are connected by the drive mechanism 30.

[0079] Among them, the flexible cover plate 10 and the display module 20 can be understood as a flexible display screen. That is to say, the flexible display screen includes the flexible cover plate 10 and the display module 20. The remaining components in the foldable electronic device 1000 provided in this application can be understood as the protection mechanism of the folding screen.

[0080] In the foldable electronic device 1000 provided in this application, the flexible display screen covers the protection mechanism, and the protection mechanism is used to support the flexible display screen. As Figure 4 shown in area 4 or area 5 in, the surface of the flexible cover plate 10 facing the protection mechanism and extending out of the display module 20 can be fixedly bonded to the housing of the protection mechanism.

[0081] The flexible cover plate 10 covers the display module 20, and can be fixedly connected to the display module 20 through back glue.

[0082] The first sliding member 50 and the second sliding member 70 are fixedly connected to the display module 20.

[0083] Among them, Figure 4 area 1 in can be understood as the first folding part, Figure 4 area 2 in can be understood as the second folding part, Figure 4 area 3 in can be understood as the folding area, and area 3 can also be called the bending area of the flexible display screen. Next, take Figure 4 the first folding part shown in area 1 in as an example for introduction. It should be understood that Figure 4 the structure of the second folding part shown in area 2 in is the same as the structure of the first folding part shown in area 1 in.

[0084] In Figure 4 area 1 in, the first sliding member 50 is fixedly connected to the first housing 40. A first slider 81 is provided on the side of the first sliding member 50 facing the first housing 40. Among them, the first slider 81 can be fixed on the first sliding member 50 by screws.

[0085] A sliding area 82 is provided on the side of the first housing 40 facing the first sliding member 50. The first slider 81 can move in the sliding area 82 in a direction parallel to the first sliding member 50.

[0086] A first gear set and a second rack are provided on the first housing 40. The first gear set is located on the side of the first housing 40 facing the driving mechanism 30, and the first gear set is located between the first housing 40 and the driving mechanism 30. The second rack is fixed to the slider of the first sliding member 50, and the second rack slides relative to the first housing 40. The sliding connection between the first housing 40 and the first sliding member 50 is realized through the first sliding area 82 and the first slider 81.

[0087] As Figure 4As shown, when the foldable electronic device 1000 changes from the folded state to the unfolded state, the driving mechanism moves horizontally away from the housing. The first rack in the driving mechanism drives the first gear set on the housing to move, and then drives the second rack on the housing to move horizontally in the direction opposite to that of the first rack. Among them, when the first rack moves a distance L1, the second rack moves a distance L2 = n * L1, where n is the reduction ratio of the first gear set.

[0088] It should be understood that Figure 4 this is only for illustration and does not impose any limitation on the protection mechanism of the folding screen and the foldable electronic device provided in this application.

[0089] Figure 5 is Figure 4 an enlarged schematic view of region 1 in

[0090] As Figure 5 shown, when the foldable electronic device 1000 is in the unfolded state, the first slider 81 moves horizontally towards the first housing 40, and the driving member 30 moves horizontally away from the first housing 40. That is to say, when the foldable electronic device 1000 is in the unfolded state, the moving directions of the first slider 81 and the driving member 30 are opposite in the horizontal direction.

[0091] It should be understood that Figure 5 this is only for illustration and does not impose any limitation on the foldable electronic device 1000 provided in the embodiments of this application.

[0092] Figure 6 is a schematic diagram of the layer structure of the foldable electronic device 1000 provided in the embodiments of this application in the folded state.

[0093] As Figure 6 shown, during the process of the foldable electronic device 1000 changing from the unfolded state to the folded state, the driving mechanism 30 moves towards the housing (see the direction indicated by the horizontal arrow in the driving mechanism 30). The first rack in the driving mechanism 30 drives the second rack to move away from the driving mechanism 30 after being decelerated by the first gear set. Further, the second rack moving away from the driving mechanism 30 drives the slider on the sliding member to move away from the driving mechanism 30 (see the direction indicated by the horizontal arrow below the sliding area 82, or see the direction indicated by the horizontal arrow above the sliding area 91). Since the sliding member moves away from the driving mechanism 30, the folding screen of the traction electronic device 1000 also moves away from the driving mechanism 30, thereby solving the delamination problem that occurs in each layer inside the foldable electronic device during the folding process.

[0094] It should be understood that in the embodiments of the present application, when an element is described as "fixed to" another element, the element can be directly or indirectly fixed to the other element; similarly, when an element is described as "connected to" another element in the embodiments of the present application, it can be a direct connection or an indirect connection.

[0095] It should also be understood that when a direction is described as "parallel" or "perpendicular" to another direction in the embodiments of the present application, it can be understood as "approximately parallel" or "approximately perpendicular".

[0096] The above is only a specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within 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.
