Description

Rotating device and foldable electronic device Technical Field

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

[0002] With the development of flexible screen technology, foldable electronic devices based on flexible screens, such as foldable mobile phones, are attracting more and more attention and favor. At present, foldable electronic devices generally include a rotating device, two shells and a flexible screen. Among them, the two shells are rotatably connected by a rotating device, and the flexible screen covers the rotating device and the two shells. In this way, the relative rotation of the two shells can be achieved through the rotating device, thereby realizing arbitrary switching between the flat state and the folded state of the foldable electronic device. Among them, the folding state of the foldable electronic device can be divided into the screen folding form and the screen folding form to meet the differentiated needs of different users.

[0003] However, when an electronic device with a foldable screen falls in a flattened state, the two shells will be subjected to external impact, causing the gap at the connection between the two shells to become smaller, thereby causing the flexible screen on the two shells to arch at the connection between the two shells. The flexible screen is very likely to have problems such as poor display, and the reliability of foldable electronic devices in the flattened state is poor.

[0004] Utility Model Content

[0005] In order to solve the above technical problems, the present application provides a rotating device and a foldable electronic device. The present application is introduced from multiple aspects below, and the implementation methods and beneficial effects of the following multiple aspects can be referenced to each other.

[0006] In a first aspect, the present application provides a rotating device. The rotating device includes a first connecting mechanism. The first connecting mechanism includes a first connecting portion. The first connecting portion includes a first connecting assembly and a second connecting assembly. The first end of the first connecting assembly is configured to be rotationally connected to a first portion of a foldable electronic device in which the rotating device is located. The second end of the first connecting assembly is rotationally connected to the first end of the second connecting assembly, and the second end of the second connecting assembly is configured to be slidingly connected to a second portion of the foldable electronic device.

[0007] The above-mentioned rotating device can effectively enhance the limiting strength of the rotating device on the first part of the foldable electronic device by rotating the first connecting component to the first part, thereby effectively improving the drop reliability of the foldable electronic device in the flat state.

[0008] In a possible implementation of the first aspect above, a rotation axis of the first part is parallel to the first direction, and a sliding direction of the second part is perpendicular to the first direction.

[0009] In one possible implementation of the first aspect, the first connecting assembly includes a first connecting member and a second connecting member, wherein the first end of the first connecting member is configured to be rotatably connected to the first portion, the second end of the first connecting member is rotatably connected to the first end of the second connecting member, and the second end of the second connecting member is rotatably connected to the first end of the second connecting assembly. The movement of the first and second connecting members can more accurately define the movement of the first connecting assembly along a predetermined trajectory.

[0010] In a possible implementation of the first aspect above, the first connecting member and the second connecting member are connecting rods respectively.

[0011] In one possible implementation of the first aspect, the rotating device further includes a main shaft assembly, the main shaft assembly including a first main shaft extending along a first direction, and the first end of the second connecting assembly is further rotatably connected to the first main shaft, thereby further improving the stability of the movement of the second connecting assembly.

[0012] In a possible implementation of the first aspect above, the first end of the second connecting assembly includes an arcuate arm, the first main shaft includes an arcuate groove corresponding to the arcuate arm, the arcuate arm is arranged in the arcuate groove, and can slide relative to the arcuate groove.

[0013] In a possible implementation of the first aspect described above, the spindle assembly further includes a second spindle extending along the first direction, the second spindle being fixedly connected to the first spindle, and the first connecting mechanism further includes a second connecting portion.

The first end of the third connecting component is rotationally connected to the second portion, and the second end of the third connecting component is rotationally connected to the first end of the fourth connecting component. The first end of the fourth connecting component is also rotationally connected to the second spindle, and the second end of the fourth connecting component is slidably connected to the first portion.

[0014] According to the implementation mode of the present application, by rotating the first part to the first connecting component and slidingly connecting it to the fourth connecting component; slidingly connecting the second part to the second connecting component and rotating it to the third connecting component, it can be ensured that the force exerted on the first part and the force exerted on the second part are relatively consistent, thereby further improving the installation stability of the first part and the second part.

[0015] In a possible implementation of the first aspect above, along the first direction, the ratio of the distance between the first connecting component and the fourth connecting component to the length of the main shaft assembly is 0.1 to 0.5, and the ratio of the distance between the second connecting component and the third connecting component to the length of the main shaft assembly is 0.1 to 0.5.

[0016] Based on this, it can be ensured that the distance between the first connecting component and the fourth connecting component is moderate, as well as the distance between the second connecting component and the third connecting component is moderate. The strength of the rotation device limit will not be weakened due to excessive distance, nor will the first connecting component, the fourth connecting component, and the second connecting component and the third connecting component interfere with each other during movement due to excessive distance.

[0017] The second aspect of the present application provides a foldable electronic device, which includes a first part, a second part, and a rotating device according to the first aspect and any possible implementation of the first aspect. The weight of the first part is greater than the weight of the second part, and the rotating device includes a plurality of connecting mechanisms, the plurality of connecting mechanisms being connected between the first part and the second part, wherein the plurality of connecting mechanisms include a first connecting mechanism, the first part being rotatably connected to the first end of the first connecting component of the first connecting mechanism, the rotation axis of the first part being parallel to the first direction, and the second part being slidably connected to the second end of the second connecting component of the first connecting mechanism, wherein along the first direction, the first connecting mechanism is closer to the first edge of the foldable electronic device than the other connecting mechanisms. The first edge is located at one end of the foldable electronic device in the first direction. The first connecting mechanism includes a plurality of connecting portions spaced apart along the first direction, the plurality of connecting portions including a first connecting portion, and along the first direction, the first connecting portion is closer to the first edge than the other connecting portions.

[0018] In this way, the limiting strength of the rotating device on the first part at the edge of the foldable electronic device can be further enhanced, thereby further enhancing the falling reliability of the foldable electronic device.

[0019] In a possible implementation of the above-mentioned second aspect, the first part includes a first mounting plate, which is rotatably connected to the first end of the first connecting component of the first connecting mechanism; the second part includes a second mounting plate, which is slidably connected to the second end of the second connecting component of the first connecting mechanism.

The first end of the fifth connecting assembly is rotatably connected to the second portion, the second end of the fifth connecting assembly is rotatably connected to the first end of the sixth connecting assembly, and the second end of the sixth connecting assembly is slidably connected to the first portion.

[0021] In one possible implementation of the second aspect, the rotating device includes a main shaft assembly, and the number of first connecting mechanisms is multiple, and the multiple first connecting mechanisms are spaced apart along the first direction on the main shaft assembly. This can further improve the drop reliability of the foldable electronic device.

[0022] In a possible implementation of the second aspect above, the plurality of first connection mechanisms are symmetrically arranged relative to a first axis, and the first axis passes through a midpoint of the spindle assembly and is perpendicular to the first direction.

[0023] By arranging multiple first connecting mechanisms symmetrically relative to the first axis, the uniformity of the force applied to the first part and the second part can be further improved, thereby effectively enhancing the limiting strength of the rotating device on the first part and the second part, thereby improving the drop reliability of the foldable electronic device.

[0024] In one possible implementation of the second aspect, the foldable electronic device further includes a through-axis flexible circuit board. The through-axis flexible circuit board extends from the first portion to the second portion via a rotating device, and the portion of the through-axis flexible circuit board corresponding to the rotating device is located between two adjacent connecting mechanisms. This further reduces the risk of damage to the through-axis flexible circuit board during a drop, thereby further improving the drop reliability of the foldable electronic device.

[0045] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0046] The “first” and “second” involved in the embodiments of the present application are merely definitions for the convenience of distinguishing components and do not represent actual meanings.

[0047] The present invention provides a rotating device and a foldable electronic device including the rotating device. The foldable electronic device provided by the present invention includes, but is not limited to, foldable mobile phones, tablet personal computers, e-book readers, laptop computers, personal digital assistants (PDAs), personal computers, notebook computers, in-vehicle devices, wearable devices (e.g., smart glasses), and other foldable electronic devices.

[0048] For the sake of convenience, the following description uses a foldable electronic device, a foldable mobile phone, as an example. Furthermore, for the sake of convenience, the state of the foldable mobile phone after being folded is defined as the folded state, and the state of the foldable mobile phone after being flattened is defined as the flattened state.

[0049] Among them, the folding state can include the screen folding state (hereinafter referred to as the "inward folding state") and the screen folding state (hereinafter referred to as the "outward folding state"). For the inward folding state, the flexible screen is located on the inner side of the folding phone. That is, when the folding phone is in the inward folding state, the user cannot observe the display interface of the flexible screen from the outside of the folding phone. For the outward folding state, the flexible screen is located on the outside of the folding phone, that is, when the folding phone is in the outward folding state, the user can observe the display interface of the flexible screen from the outside of the folding phone.

[0050] Alternatively, the foldable phone can have a tri-fold structure. A tri-fold structure refers to a foldable phone comprising three housings and two rotating devices, with adjacent housings connected by a rotating device. The adjacent housings can be rotated toward each other by folding inward or outward until the angle between them is approximately 0°, placing the foldable phone in an inward or outward folded state. The adjacent housings can also be rotated away from each other until the angle between them is approximately 180°, placing the foldable phone in a flattened state.

[0051] Alternatively, in other embodiments, the foldable phone may have other structural forms. For example, the foldable phone may have a two-fold structure, that is, the foldable phone includes two housings and a rotating device connected between the two housings. The two housings can rotate relative to each other via the rotating device, thereby allowing the foldable phone to switch between a folded state (e.g., the aforementioned inward-folded state or outward-folded state) and a flattened state at will.

[0052] The following describes the foldable electronic device provided in an embodiment of the present application by taking a foldable mobile phone with a three-fold structure, in which one group of two adjacent shells are folded in an outward folding manner and another group of two adjacent shells are folded in an inward folding manner as an example.

[0053] Specifically, Figures 1A to 1C show structural schematic diagrams of the folding mobile phone 1 in an embodiment of the present application, wherein Figure 1A is a three-dimensional diagram of the folding mobile phone 1 in a flattened state, Figure 1B is a three-dimensional diagram of the folding mobile phone 1 in a folded state, and Figure 1C is an exploded diagram of the folding mobile phone 1 in a flattened state.

[0054] To facilitate subsequent description, before describing the specific structure of the foldable phone 1, we will first introduce exemplary directions of the foldable phone 1 with reference to Figures 1A to 1C. Referring to Figures 1A to 1C, the X-axis, Y-axis, and Z-axis directions are defined. As shown in Figures 1A to 1C, the X-axis direction is the length direction of the foldable phone 1 in the unfolded state; the Z-axis direction is the thickness direction of the foldable phone 1 in the unfolded state; and the Y-axis direction is perpendicular to both the X-axis and Z-axis directions.

[0055] It is understood that the term "perpendicular" in this application is not absolute. Approximate perpendicularity due to processing and assembly errors (for example, an angle of 89.9° between two structural features) is also within the scope of "perpendicular" in this application. This application does not make any specific restrictions on this, and the definition of "perpendicular" will not be repeated below.

[0056] 1A to 1C , the foldable phone 1 includes a rotating device 10 , a rotating device 20 , a first housing 30 , a second housing 40 , a third housing 50 , a flexible screen 60 , and a screen supporting plate 70 .

[0057] Among them, along the X-axis direction, the rotating device 10 is connected between the first shell 30 and the second shell 40. The rotating device 20 is connected between the first shell 30 and the third shell 50. The flexible screen 60 is fixed to the first shell 30, the second shell 40 and the third shell 50, and covers the rotating device 10, the rotating device 20, the first shell 30, the second shell 40 and the third shell 50. A screen support plate 70 can be provided on the inner surface of the flexible screen 60 to provide support for the flexible screen 60 and prevent the flexible screen 60 from being suspended in the air. For example, the screen support plate 70 can be bonded to the first shell 30, the second shell 40 and the third shell 50 by adhesive 80.

[0058] The first shell 30 and the second shell 40 can rotate relative to each other through the rotating device 10, and the first shell 30 and the third shell 50 can rotate relative to each other through the rotating device 20, and the flexible screen 60 also moves accordingly and presents a flattened state or a bent state, so that the foldable mobile phone 1 can switch between the flattened state and the folded state at will.

[0059] When the foldable phone 1 is in a flattened state (for example, the flattened state shown in FIG1A ), the angle between two adjacent shells among the first shell 30, the second shell 40 and the third shell 50 can be approximately 180°. The first shell 30, the second shell 40 and the third shell 50 are arranged side by side along the X-axis direction, and the flexible screen 60 is flattened in a shape similar to a "one" and can perform full-screen display, so that the foldable phone 1 has a larger display area to improve the user's viewing experience and operating experience.

[0060] When the foldable phone 1 is in a folded state (for example, the folded state shown in FIG1B ), the angle between two adjacent shells among the first shell 30, the second shell 40 and the third shell 50 can be approximately 0°. The first shell 30, the second shell 40 and the third shell 50 are stacked along the Z-axis direction, and the flexible screen 60 is also bent accordingly, so that the planar size of the foldable phone 1 is smaller, which is convenient for users to carry and store.

[0061] The portion of the flexible screen 60 corresponding to the first housing 30 and the third housing 50 (e.g., the flexible screen 60a shown in FIG1B ) is located on the inner side of the foldable phone 1, while the portion of the flexible screen 60 corresponding to the second housing 40 (e.g., the flexible screen 60b shown in FIG1B ) is located on the outer side of the foldable phone 1. In other words, the first housing 30 and the second housing 40 fold outward, and accordingly, the rotating device 10 is an outward-folding rotating device. The first housing 30 and the third housing 50 fold inward, and accordingly, the rotating device 20 is an inward-folding rotating device.

[0062] Continuing with FIG1A , along the X-axis, the outward-folding rotating device 10 can separate the foldable phone 1 into a first portion 11 and a second portion 12, with the first portion 11 being heavier than the second portion 12. For example, in this embodiment, the first portion 11 includes a first housing 30, a third housing 50, and a rotating device 20 connected between the first and third housings 30, 50, while the second portion 12 includes a second housing 40.

[0063] It should be understood that FIG1A schematically illustrates only some of the structural components of the first portion 11 and the second portion 12 of the foldable phone 1. The actual configuration and location of these structural components are not limited to FIG1A , and the first portion 11 and the second portion 12 may also include more or fewer structural components than those shown in FIG1A . For example, in other embodiments, the foldable phone 1 has a two-fold structure, the first portion 11 may include the first housing 30 but not the third housing 50 and the rotating device 20, and the second portion 12 may include the second housing 40.

[0064] As mentioned above, in some technical solutions, when a folding mobile phone in an outward-folding form falls in a flattened state, its first part and / or second part will be subjected to external impact, thereby reducing the gap at the connection between the first shell of the first part and the second shell of the second part, thereby causing the flexible screen to arch at the connection between the first shell and the second shell. The following is a detailed introduction in combination with the exemplary structure of the outward-folding rotating device.

[0065] Figure 2 shows a schematic diagram of the structure of an outward-folding rotating device 10a in a foldable mobile phone 1a according to some technical solutions. As shown in Figure 2, the rotating device 10a includes a first connecting mechanism 100a and a main shaft assembly 200a. The connecting mechanism 100a includes a first connecting assembly 110a, a second connecting assembly 120a, a first mounting plate 130a, and a second mounting plate 140a.

[0066] One end of the first connecting assembly 110a is rotatably connected to the spindle assembly 200a, and the other end is slidably connected to the first mounting plate 130a. The first mounting plate 130a is fixedly connected to the first housing 30a of the first portion 11a, thereby connecting the rotating device 10a to the first housing 30a. One end of the second connecting assembly 120a is rotatably connected to the spindle assembly 200a, and the other end is slidably connected to one end of the second mounting plate 140a. The second mounting plate 140a is fixedly connected to the second housing 40a, thereby connecting the rotating device 10a to the second housing 40a of the second portion 12a.

[0067] Since the first connecting component 110a and the first mounting plate 130a, and the second connecting component 120a and the second mounting plate 140a are all slidingly connected, the rotating device 10a has a weak limiting effect on the first shell 30a and the second shell 40a along the X-axis direction. The first shell 30a and the second shell 40a are very likely to produce relative displacement along the X-axis direction under the action of external force, thereby causing the flexible screen 60a to arch and cause damage to the flexible screen 60a.

[0068] For example, Figure 3 illustrates a schematic diagram of the bulging of the flexible screen 60a in a foldable phone 1a in some technical solutions. Referring to Figure 3 , when the foldable phone 1a, in its flattened state, falls to the ground 2 along the positive X-axis direction (direction A in Figure 3 ), external forces cause the first mounting plate 130a to slide relative to the first connecting assembly 110a along the positive X-axis direction, while the second mounting plate 140a slides relative to the second connecting assembly 120a along the negative X-axis direction. Due to the greater overall weight of the first portion 11a, inertia causes the first mounting plate 130a of the first portion 11a to experience a significant relative displacement relative to the first connecting assembly 110a along the positive X-axis direction. This significantly reduces the gap at the connection between the first housing 30a and the second housing 40a, leading to a significant upward bulge in the portion of the flexible screen 60a corresponding to the rotating device 10a (e.g., region S1 in Figure 3 ). This increases local stress on the flexible screen 60a, making it susceptible to damage.

[0069] To solve the above problems, an embodiment of the present application provides an outward-folding rotating device for a folding mobile phone. Compared with the above-mentioned outward-folding rotating device 10a, the first connecting component in the outward-folding rotating device provided by the present application is rotatably connected to the first part of the folding mobile phone, which can further enhance the limiting effect of the rotating device on the first shell of the first part along the X-axis direction, thereby reducing the displacement of the first shell along the X-axis direction under the impact of external force, reducing the risk of the flexible screen arching when the folding mobile phone falls in the flattened state, and thereby effectively improving the falling reliability of the folding mobile phone when it is in the flattened state. The technical solution of the present application is introduced below in conjunction with the accompanying drawings.

[0070] Figure 4A shows a schematic diagram of the structure of the foldable phone 1 according to an embodiment of the present application. Figure 4B shows an enlarged partial view of the foldable phone 1 at the S2 region in Figure 4A according to an embodiment of the present application, wherein the main shaft assembly 200 is shown in dashed lines. Figure 4C shows a perspective view of the rotating device 10 in the foldable phone 1 according to an embodiment of the present application, wherein the second mounting plate 140 and the main shaft assembly 200 are shown in dashed lines.

[0071] 4A to 4C , the foldable phone 1 includes a rotating device 10 , a rotating device 20 , a first housing 30 , a second housing 40 , a third housing 50 , a flexible screen 60 , and a screen supporting plate 70 .

[0072] As described above, in the embodiment of the present application, the first shell 30 and the second shell 40 are rotationally connected by the rotating device 10, and the first shell 30 and the third shell 50 are rotationally connected by the rotating device 20. The flexible screen 60 and the screen support plate 70 are stacked from top to bottom along the Z-axis direction on the rotating device 10, the rotating device 20, the first shell 30, the second shell 40 and the third shell 50. Among them, the functions of the various components in the folding mobile phone 1 can be referred to the above description and will not be repeated here. The following focuses on the structure of the rotating device 10 provided in the embodiment of the present application, as well as the installation method between the rotating device 10 and the first shell 30 of the first part 11 and the second shell 40 of the second part 12.

[0073] 4A to 4C , the rotating device 10 includes a first connecting mechanism 100 . The first connecting mechanism 100 includes a first connecting portion 101 . The first connecting portion 101 includes a first connecting assembly 110 and a second connecting assembly 120 .

[0074] The first end 111 of the first connecting assembly 110 is rotatably connected to the first portion 11. The rotation axis of the first portion 11 can be parallel to the Y-axis direction (as an example of the first direction). For example, the first portion 11 can include a first mounting plate 130. The first end 111 of the first connecting assembly 110 can be rotatably connected to the first mounting plate 130 of the first portion 11, and the first mounting plate 130 is fixedly connected to the first housing 30 of the first portion 11.

[0075] The second end 112 of the first connecting assembly 110 is rotatably connected to the first end 121 of the second connecting assembly 120. The second end 122 of the second connecting assembly 120 is slidably connected to the second portion 12. The sliding direction of the second portion 12 can be the X-axis. For example, the second portion 12 may include a second mounting plate 140. The second end 122 of the second connecting assembly 120 can be slidably connected to the second mounting plate 140. The second mounting plate 140 is fixedly connected to the second housing 40 of the second portion 12.

[0076] The aforementioned rotating device 10, by rotatably connecting the first connecting assembly 110 to the first portion 11, can effectively enhance the strength of the rotating device 10 in restraining the first housing 30 along the X-axis. Therefore, when the foldable phone 1 is dropped in the flattened state, the first housing 30 will not undergo significant displacement due to the inertia of the first portion 11. This effectively prevents significant changes in the gap at the connection between the first housing 30 and the second housing 40, thereby reducing the risk of the flexible screen 60 arching and effectively improving the drop reliability of the foldable phone 1 in the flattened state.

[0077] The specific structure and installation method of each component in the first connecting mechanism 100 in the rotating device 10 will be further described below with reference to the accompanying drawings.

[0078] Figures 5A and 5B illustrate schematic structural diagrams of the first connecting assembly 110 and the second connecting assembly 120 in the first connecting mechanism 100 in an embodiment of the present application, wherein Figure 5A is a perspective view of the first connecting assembly 110 and the second connecting assembly 120, and Figure 5B is an exploded view of the first connecting assembly 110 and the second connecting assembly 120. Referring to Figures 5A and 5B in conjunction with Figures 4B and 4C, in some embodiments of the present application, the first connecting assembly 110 includes a first connecting member 113 and a second connecting member 114.

[0079] The first end 1131 of the first connector 113 is rotatably connected to the first mounting plate 130. The second end 1132 of the first connector 113 is rotatably connected to the first end 1141 of the second connector 114. The second end 1141 of the second connector 114 is rotatably connected to the first end 121 of the second connecting assembly 120.

[0080] It can be understood that the first end 1131 of the first connector 113 shown in Figures 5A and 5B is the first end 111 of the first connector assembly 110 shown in Figures 4B and 4C. The second end 1142 of the second connector 114 shown in Figures 5A and 5B is the second end 112 of the first connector assembly 110 shown in Figures 4B and 4C.

[0081] The above-mentioned rotating device 10 can more accurately limit the movement of the first connecting component 110 along the set trajectory through the movement of the first connecting member 113 and the second connecting member 114, thereby ensuring that the first shell 30 and the second shell 40 in the unfolded state and the folded state can be located in a specific position, avoiding the flexible screen 60 from being squeezed or pulled, so that the foldable mobile phone 1 can be flattened or folded normally.

[0082] In some embodiments of the present application, the first connecting member 113 and the second connecting member 114 may be connecting rods respectively.

[0083] In some embodiments of the present application, the rotational connection between the first connecting member 113 and the first mounting plate 130 can be achieved through a pin.

[0084] In some embodiments of the present application, the rotational connection between the second end 1132 of the first connecting member 113 and the first end 1141 of the second connecting member 114 can be achieved by a pin.

[0085] In some embodiments of the present application, the second end 1142 of the second connector 114 may include a mounting portion 1143 extending along the Y-axis. The first end 121 of the second connecting assembly 120 may define a mounting cavity 123 that matches the shape of the mounting portion 1143. The mounting portion 1143 is disposed within the mounting cavity 123 and can slide along the inner surface of the mounting cavity 123, thereby achieving a rotational connection between the second connector 114 and the second connecting assembly 120.

[0086] Continuing to refer to Figures 4B and 4C in conjunction with Figures 5A and 5B, in some embodiments of the present application, the rotating device 10 may further include a spindle assembly 200. The spindle assembly 200 includes a first spindle 210 extending along the Y-axis. The connection between the second connecting member 114 and the second connecting assembly 120 may be located within the first spindle 210, and the first end 121 of the second connecting assembly 120 may be rotatably connected to the first spindle 210, thereby further improving the stability of the movement of the first connecting mechanism 100 and ensuring more stable rotation of the first shell 30 and the second shell 40.

[0087] It should be understood that FIG4C only illustrates a portion of the main shaft assembly 200 with dashed lines and does not represent the full length of the main shaft assembly 200. For example, as shown in FIG8A to FIG13 below, the two ends of the main shaft assembly 200 can extend along the Y-axis to the two edges of the foldable phone 1.

[0088] Figures 6A and 6B illustrate the rotatable connection between the first end 121 of the second connecting assembly 120 and the first main shaft 210 in an embodiment of the present application. In Figure 6A , the rotating device 10 is in the unfolded state, at which point the angle between the first mounting plate 130 and the second mounting plate 140 is approximately 180°. In Figure 6B , the rotating device 10 is in the folded-out state, at which point the angle between the first mounting plate 130 and the second mounting plate 140 is approximately 0°.

[0089] 6A and 6B in conjunction with FIG5A and 5B , the first end 121 of the second connecting assembly 120 includes an arcuate arm 1211. The first main shaft 210 includes an arcuate slot 201 that matches the shape of the arcuate arm 1211. The arcuate arm 1211 is disposed within the arcuate slot 201 and is capable of sliding relative to the arcuate slot 201, thereby achieving a rotational connection between the second connecting assembly 120 and the first main shaft 210, so that the rotating device 10 can be switched between an expanded state (e.g., the expanded state shown in FIG6A ) and an outwardly folded state (e.g., the outwardly folded state shown in FIG6B ).

[0090] In some embodiments of the present application, the arcuate arm 1211 can be used to rotatably connect to the second end 1142 of the second connector 114 (i.e., the second end 112 of the first connector assembly 110). For example, the mounting cavity 123 can be provided on the arcuate arm 1211 at the first end 121. The mounting cavity 123 cooperates with the mounting portion 1143 to achieve a rotatable connection between the second end 1142 of the second connector 114 and the arcuate arm 1211, thereby achieving a rotatable connection between the second end 1142 of the second connector 114 and the first end 121 of the second connector assembly 120.

[0091] In some embodiments of the present application, the second end 122 of the second connecting component 120 can be slidably connected to the second mounting plate 140 to ensure that the first shell 30 and the second shell 40 in the unfolded state and the folded state can be located in specific positions, thereby realizing the function of flattening or folding the foldable mobile phone 1.

[0092] For example, FIG7 shows a schematic diagram of the sliding connection between the second connecting assembly 120 and the second mounting plate 140 in an embodiment of the present application. Referring to FIG7 and in conjunction with FIG6A and FIG6B , a slider 1221 is provided on the second end 122 of the second connecting assembly 120. A slot 141 corresponding to the slider 1221 is defined on the second mounting plate 140. The slider 1221 is disposed in the slot 141 and is capable of sliding relative to the slot 141 along the X-axis direction (a direction perpendicular to the paper in FIG7 ), thereby achieving a sliding connection between the second end 122 of the second connecting assembly 120 and the second mounting plate 140.

[0093] Alternatively, in other alternative embodiments, a sliding groove may be provided on the second end 122 of the second connecting assembly 120. A slider may be provided on the second mounting plate 140. This application does not impose any restrictions on this. Any connection method that allows the second end 122 of the second connecting assembly 120 to slide and connect to the second mounting plate 140 is within the scope of protection of this application.

[0094] Continuing to refer to FIG. 4C in conjunction with FIG. 4B , in some embodiments of the present application, the rotating device 10 may further include a second connecting portion 102. The second connecting portion 102 is spaced apart from the first connecting portion 101 along the Y-axis direction to further enhance the mounting stability of the first mounting plate 130 and the second mounting plate 140, thereby enhancing the mounting stability of the first housing 30 and the second housing 40.

[0095] Specifically, the second connecting portion 102 includes a third connecting assembly 150 and a fourth connecting assembly 160. The third connecting assembly 150 and the fourth connecting assembly 160 are spaced apart from the first connecting assembly 110 and the second connecting assembly 120 along the Y-axis. The first end 151 of the third connecting assembly 150 is rotatably connected to the second mounting plate 140. The second end 152 of the third connecting assembly 150 is rotatably connected to the first end 161 of the fourth connecting assembly 160.

[0096] The spindle assembly 200 further includes a second spindle 220 extending along the Y-axis, and the second spindle 220 is fixedly connected to the first spindle 210. The first end 161 of the fourth connecting assembly 160 is also rotatably connected to the second spindle 220. The second end 162 of the fourth connecting assembly 160 is slidably connected to the first mounting plate 130.

[0097] The above-mentioned rotating device 10, by rotatingly connecting the first mounting plate 130 with the first connecting component 110 and slidingly connecting it with the fourth connecting component 160; slidingly connecting the second mounting plate 140 with the second connecting component 120, and rotatingly connecting it with the third connecting component 150, can ensure that the force exerted on the first mounting plate 130 and the force exerted on the second mounting plate 140 are relatively consistent, thereby further improving the installation stability of the first mounting plate 130 and the second mounting plate 140, and further improving the installation stability of the first shell 30 and the second shell 40.

[0098] In some embodiments of the present application, the structure of the third connecting assembly 150 can be the same as that of the first connecting assembly 110 described above; the structure of the fourth connecting assembly 160 can be the same as that of the second connecting assembly 120 described above. Accordingly, the rotational connection of the third connecting assembly 150 to the fourth connecting assembly 160 can be implemented in the same manner as the rotational connection of the first connecting assembly 110 to the second connecting assembly 120 described above. For details, please refer to Figures 5A and 5B and the related descriptions, and will not be repeated here.

[0099] In addition, the implementation method of the third connecting component 150 rotating and connecting to the second mounting plate 140 can be the same as the implementation method of the above-mentioned first connecting component 110 rotating and connecting to the first mounting plate 130; the implementation method of the fourth connecting component 160 slidingly connecting to the first mounting plate 130 can be the same as the implementation method of the above-mentioned second connecting component 120 slidingly connecting to the second mounting plate 140; the implementation method of the fourth connecting component 160 rotating and connecting to the second main shaft 220 can be the same as the implementation method of the above-mentioned second connecting component 120 rotating and connecting to the first main shaft 210. For details, please refer to Figures 6A to 7 and their related descriptions, and will not be repeated here.

[0100] Continuing with FIG. 4C , in some embodiments of the present application, along the Y-axis, the ratio of the distance between the first connecting component 110 and the fourth connecting component 160 to the length of the spindle assembly 200 is 0.1 to 0.5, for example, 0.1, 0.2, 0.3, etc. The ratio of the distance between the second connecting component 120 and the third connecting component 150 to the length of the spindle assembly 200 is also 0.1 to 0.5, for example, 0.1, 0.2, 0.3, etc.

[0101] Based on this, it can be ensured that the distance between the first connecting component 110 and the fourth connecting component 160 is moderate, and the distance between the second connecting component 120 and the third connecting component 150 is moderate. The installation stability of the first mounting plate 130 and the second mounting plate 140 in the first connecting mechanism 100 will not be weakened due to excessive distance, and the first connecting component 110, the fourth connecting component 160, and the second connecting component 120, the third connecting component 150 will not interfere with each other during movement due to excessive distance.

[0102] In some embodiments of the present application, the number of first connecting mechanisms 100 in the rotating device 10 can be multiple. The multiple first connecting mechanisms 100 are arranged at intervals along the Y-axis. By using multiple first connecting mechanisms 100 to achieve the rotational connection between the first shell 30 and the second shell 40, the rotational connection between the first shell 30 and the second shell 40 can be effectively enhanced. The position restriction of the first shell 30 along the X-axis by the rotating device 10 can further improve the drop reliability of the foldable mobile phone 1.

[0103] For example, the number of first connecting mechanisms 100 in the rotating device 10 can be two, three, four, etc. Below, taking the rotating device 10 including four first connecting mechanisms 100 as an example, several layout schemes of the first connecting mechanisms 100 in the foldable phone 1 will be described in detail with reference to the accompanying drawings.

[0104] Figures 8A and 8B illustrate an exemplary layout of the first connecting mechanism 100 in a foldable phone 1 according to an embodiment of the present application. Figure 8A is a top view of the foldable phone 1, and Figure 8B is a partially enlarged view of the foldable phone 1 at the rotating mechanism 10. Referring to Figures 8A and 8B, in some embodiments of the present application, the rotating mechanism 10 includes a connecting mechanism 100-1, a connecting mechanism 100-2, a connecting mechanism 100-3, and a connecting mechanism 100-4. Along the Y-axis, connecting mechanisms 100-1, 100-2, 100-3, and 100-4 are sequentially spaced apart.

[0105] It is worth noting that, due to the influence of the structure of the flexible screen (not shown), the connection strength between its edges and the rotating device 10, the first shell 30, and the second shell 40 is relatively weak, making it more prone to deformation.

[0106] To this end, in some embodiments of the present application, along the Y-axis, one of the first connecting mechanisms is closer to the first edge S3 of the foldable phone 1 than the other connecting mechanisms, and the first connecting portion of the first connecting mechanism is closer to the first edge S3 of the foldable phone 1 than the other connecting portions. This further enhances the X-axis restraining strength of the rotating device 10 on the edge of the foldable phone 1, thereby effectively preventing displacement of the first housing 30 along the X-axis, which could cause the flexible screen to bulge at its edge.

[0107] For example, as shown in Figure 8B, along the Y-axis direction, the connecting mechanism 100-1 (as an example of the above-mentioned first connecting mechanism) is closer to the first edge S3 of the folding mobile phone 1 than the connecting mechanism 100-2, the connecting mechanism 100-3 and the connecting mechanism 100-4; and the first connecting part 101-1 of the connecting mechanism 100-1 is closer to the first edge S3 of the folding mobile phone 1 than the second connecting part 102-1 (as an example of the above-mentioned other connecting parts).

[0108] It should be noted that the other connecting mechanisms herein refer to connecting mechanisms that are physically independent of the first connecting mechanism. The other connecting parts refer to connecting parts in the first connecting mechanism that are physically independent of the first connecting part.

[0109] The components and the connection methods between the components of the other connecting mechanisms described in the above embodiments (e.g., connecting mechanisms 100-2, 100-3, and 100-4 shown in FIG8B ) are the same as those of the first connecting mechanism (e.g., connecting mechanism 100-1 shown in FIG8B ). In other embodiments, the other connecting mechanisms may also have other forms (e.g., connecting mechanism 100-4 shown in FIG13 below), and this application does not impose any limitation on this.

[0110] 8B , in some embodiments of the present application, the connection mechanisms 100 - 1 , 100 - 2 , 100 - 3 , and 100 - 4 may be symmetrically arranged relative to the first axis L1 , which passes through the midpoint P of the spindle assembly 200 and is perpendicular to the Y-axis.

[0111] It can be understood that the layout of the components in the connecting mechanism 100-1 (for example, the first connecting component 110-1, the second connecting component 120-1, the first mounting plate 130-1, the second mounting plate 140-1, the third connecting component 150-1 and the fourth connecting component 160-1) is symmetrical relative to the first axis L1 with respect to the layout of the components in the connecting mechanism 100-4 (for example, the first connecting component 110-4, the second connecting component 120-4, the first mounting plate 130-4, the second mounting plate 140-4, the third connecting component 150-4 and the fourth connecting component 160-4).

[0112] That is, the connection mechanism 100 - 1 is mirrored relative to the first axis L1 , and the mirrored connection mechanism 100 - 1 completely overlaps with the connection mechanism 100 - 4 .

[0113] The layout of the components in the second connecting mechanism 100-2 (for example, the first connecting component 110-2, the second connecting component 120-2, the first mounting plate 130-2, the second mounting plate 140-2, the third connecting component 150-2 and the fourth connecting component 160-2) is symmetrical relative to the first axis L1 with respect to the layout of the components in the connecting mechanism 100-3 (for example, the first connecting component 110-3, the second connecting component 120-3, the first mounting plate 130-3, the second mounting plate 140-3, the third connecting component 150-3 and the fourth connecting component 160-3).

[0114] That is, the connection mechanism 100 - 2 is mirrored relative to the first axis L1 , and the mirrored connection mechanism 100 - 2 completely overlaps with the connection mechanism 100 - 3 .

[0115] By arranging multiple first connecting mechanisms (for example, the above-mentioned connecting mechanism 100-1, connecting mechanism 100-2, connecting mechanism 100-3 and connecting mechanism 100-4) symmetrically relative to the first axis L1, the uniformity of the force applied to the first shell 30 and the second shell 40 can be further improved, thereby effectively enhancing the limiting strength of the rotating device 10 on the first shell 30 and the second shell 40, avoiding the problem of failure of the flexible screen 60 due to falling, and thereby improving the falling reliability of the folding mobile phone 1.

[0116] It is understood that Figures 8A and 8B only schematically illustrate the symmetrical arrangement of the connecting mechanisms 100-1, 100-2, 100-3, and 100-4, but the present application is not limited thereto. In other alternative embodiments, the connecting mechanisms 100-1, 100-2, 100-3, and 100-4 may also have other types of symmetrical arrangements.

[0117] For example, Figure 9 illustrates a second exemplary layout of the first connecting mechanism 100 in the foldable mobile phone 1 according to an embodiment of the present application. Referring to Figure 9 , in other embodiments of the present application, the connecting mechanisms 100-1 and 100-2 are symmetrically arranged relative to the second axis L2. The connecting mechanisms 100-3 and 100-4 are symmetrically arranged relative to the third axis L3. The first axis L1 and the second axis L2 can be symmetrically arranged relative to the first axis L1 and are both perpendicular to the Y-axis.

[0118] It can be understood that the layout of the components in the connecting mechanism 100-1 (for example, the first connecting component 110-1, the second connecting component 120-1, the first mounting plate 130-1, the second mounting plate 140-1, the third connecting component 150-1 and the fourth connecting component 160-1) is symmetrical relative to the second axis L2 with respect to the layout of the components in the connecting mechanism 100-2 (for example, the first connecting component 110-2, the second connecting component 120-2, the first mounting plate 130-2, the second mounting plate 140-2, the third connecting component 150-2 and the fourth connecting component 160-2).

[0119] That is, the connection mechanism 100 - 1 is mirrored relative to the second axis L2 , and the connection mechanism 100 - 1 after the mirroring is completely overlapped with the connection mechanism 100 - 2 .

[0120] The layout of the components in the connecting mechanism 100-3 (for example, the first connecting component 110-3, the second connecting component 120-3, the first mounting plate 130-3, the second mounting plate 140-3, the third connecting component 150-3 and the fourth connecting component 160-3) is symmetrical relative to the third axis L3 with respect to the layout of the components in the connecting mechanism 100-4 (for example, the first connecting component 110-4, the second connecting component 120-4, the first mounting plate 130-4, the second mounting plate 140-4, the third connecting component 150-4 and the fourth connecting component 160-4).

[0121] That is, the connection mechanism 100 - 3 is mirrored relative to the third axis L3 , and the mirrored connection mechanism 100 - 3 completely overlaps with the connection mechanism 100 - 4 .

[0122] By symmetrically arranging the connecting mechanism 100-1 and the connecting mechanism 100-2 relative to the second axis L2, and symmetrically arranging the connecting mechanism 100-3 and the connecting mechanism 100-4 relative to the third axis L3, the uniformity of the force applied to the first shell 30 and the second shell 40 can also be further improved, thereby effectively enhancing the limiting strength of the rotating device 10 on the first shell 30 and the second shell 40, solving the problem of failure of the flexible screen 60 due to falling, and thereby improving the falling reliability of the folding mobile phone 1.

[0123] Figure 10 illustrates a third exemplary layout of the first connecting mechanism 100 in the foldable phone 1 according to an embodiment of the present application. Referring to Figure 10 , in some embodiments of the present application, the layout of the components of connecting mechanism 100-1, connecting mechanism 100-2, connecting mechanism 100-3, and connecting mechanism 100-4 can be identical. In other words, by performing multiple translations of connecting mechanism 100-1 along the Y-axis, the connecting mechanism 100-1 can be completely aligned with connecting mechanism 100-2, connecting mechanism 100-3, and connecting mechanism 100-4, respectively.

[0124] In this way, the same set of production molds can be used to manufacture the various components of the connecting mechanism 100 - 1 , the connecting mechanism 100 - 2 , the connecting mechanism 100 - 3 and the connecting mechanism 100 - 4 , thereby further reducing production costs.

[0125] Continuing to refer to Figure 10, in some implementations, along the Y-axis direction, the distance between the connecting mechanism 100-1 and the first axis L1 is equal to the distance between the connecting mechanism 100-4 and the first axis L1; the distance between the connecting mechanism 100-2 and the first axis L1 is equal to the distance between the connecting mechanism 100-3 and the first axis L1, thereby further improving the uniformity of force on the first shell 30 and the second shell 40.

[0126] In some other implementations, the distances between the connecting mechanism 100-1, the connecting mechanism 100-2, the connecting mechanism 100-3, and the connecting mechanism 100-4 and the first axis L1 may not be completely equal. For example, Figure 11 shows an exemplary layout of the first connecting mechanism 100 in the folding mobile phone 1 in an embodiment of the present application. Referring to Figure 11, along the Y-axis direction, the connecting mechanism 100-1 and the connecting mechanism 100-2 are arranged on the left side of the first axis L1, the connecting mechanism 100-3 is arranged at a position corresponding to the first axis L1, and the connecting mechanism 100-4 is arranged on the right side of the first axis L1. The distances between the connecting mechanism 100-1, the connecting mechanism 100-2, the connecting mechanism 100-3, and the connecting mechanism 100-4 and the first axis L1 are not equal.

[0127] It can be understood that the structural forms of the connecting mechanisms 100-1, 100-2, 100-3 and 100-4 in the above-mentioned rotating device 10 are only exemplary descriptions of the technical solution of this application, and people skilled in the art can make other modifications.

[0128] For example, in this embodiment, the connection mechanisms 100-1, 100-2, 100-3, and 100-4 each include a first connection component (e.g., first connection components 110-1, 110-2, 110-3, and 110-4), a second connection component (e.g., second connection components 120-1, 120-2, 120-3, and 120-4), a third connection component (e.g., third connection components 150-1, 150-2, 150-3, and 150-4), and a fourth connection component (e.g., fourth connection components 160-1, 160-2, 160-3, and 160-4). In other embodiments, any one or more of the connection mechanisms 100-1, 100-2, 100-3, and 100-4 may also include a first connection component and a second connection component, but not include a third connection component and a fourth connection component.

[0129] For example, Figure 12 shows an exemplary structure of the rotating device 10 in some other embodiments of the foldable mobile phone 1 of the present application. Referring to Figure 12, the rotating device 10 includes a connecting mechanism 100-1, a connecting mechanism 100-2, a connecting mechanism 100-3, and a connecting mechanism 100-4, which are sequentially spaced along the Y-axis.

[0130] The connection mechanism 100-3 includes a first connection component 110-3 and a second connection component 120-3. The connection mechanisms 100-1, 100-2, and 100-4 each include a first connection component (e.g., first connection components 110-1, 110-2, 110-4), a second connection component (e.g., second connection components 120-1, 120-2, 120-4), a third connection component (e.g., third connection components 150-1, 150-2, 150-4), and a fourth connection component (e.g., fourth connection components 160-1, 160-2, 160-4).

[0131] For example, in other embodiments, any one or more of the connection mechanisms 100 - 1 , 100 - 2 , 100 - 3 , and 100 - 4 may also include a third connection component and a fourth connection component, but not the first connection component and the second connection component.

[0132] For example, Figure 13 shows an exemplary structure of the rotating device 10 in the foldable mobile phone 1 in other embodiments of the present application. Referring to Figure 13, the rotating device 10 includes a connecting mechanism 100-1, a connecting mechanism 100-2, a connecting mechanism 100-3, and a connecting mechanism 100-4, which are sequentially spaced along the Y-axis.

[0133] The connecting mechanism 100-4 (as an example of a second connecting mechanism) includes a third connecting assembly 150-4 (as an example of a fifth connecting assembly) and a fourth connecting assembly 160-4 (as an example of a sixth connecting assembly). The third connecting assembly 150-4 is rotationally connected to the second mounting plate 140-4. The fourth connecting assembly 160-4 is slidably connected to the first mounting plate 130-4.

[0134] Connecting mechanism 100-1, connecting mechanism 100-2 and connecting mechanism 100-3 all include a first connecting component (e.g., first connecting component 110-1, 110-2, 110-3), a second connecting component (e.g., second connecting component 120-1, 120-2, 120-3), a third connecting component (e.g., third connecting component 150-1, 150-2, 150-3) and a fourth connecting component (e.g., fourth connecting component 160-1, 160-2, 160-3).

[0135] It is understood that the structural forms of the connecting mechanisms in the above embodiments are only some of the embodiments of this application. In other application scenarios, when the rotating device 10 of the foldable mobile phone 1 includes multiple connecting mechanisms (for example, the above-mentioned connecting mechanisms 100-1, 100-2, 100-3, and 100-4), the structural solutions of the connecting mechanisms can be arbitrarily disassembled or reorganized, and this application does not specifically limit them. Any structural form of the connecting mechanism that can improve the drop reliability of the foldable mobile phone 1 is within the scope of protection of this application.

[0136] In addition, it can be understood that the above embodiment only uses the outward folding rotating device 10 connected between the first shell 30 and the second shell 40 as an example to introduce the structural form and installation method of the rotating device provided by the present application.

[0137] In other embodiments, the rotating device 20 connected between the first shell 30 and the third shell 50 may also be an outward-folding rotating device. The structure of the outward-folding rotating device 20 is substantially the same as the structure of the outward-folding rotating device 10 connected between the first shell 30 and the second shell 40 described above, with only the installation orientation being modified accordingly. A detailed description thereof will not be repeated here.

[0138] Continuing with Figures 8A to 13 , the foldable phone 1 may further include a through-axis flexible circuit board (FPC) 90, hereinafter referred to as through-axis FPC 90. The through-axis FPC 90 passes through the rotating device 10 along the X-axis direction, and the two ends of the through-axis FPC 90 extend into the first housing 30 and the second housing 40, respectively, to facilitate connection with electronic components (e.g., circuit boards, chips, etc.) in the first housing 30 and the second housing 40, thereby enabling signal transmission.

[0139] In some embodiments of the present application, the through-axis FPC 90 can be arranged between two adjacent connecting mechanisms (for example, connecting mechanism 100-1, connecting mechanism 100-2, connecting mechanism 100-3 and connecting mechanism 100-4), thereby further reducing the risk of damage to the through-axis FPC 90 during a fall, and further improving the fall reliability of the folding mobile phone 1.

[0140] For example, as shown in FIG. 8A to FIG. 10 , in some implementations, the through-axis FPC 90 may be located between the connection mechanism 100 - 2 and the connection mechanism 100 - 3 and disposed corresponding to the first axis L1 .

[0141] As shown in FIG. 11 to FIG. 13 , in some other implementations, the through-axis FPC 90 may also be located between the connection mechanism 100 - 3 and the connection mechanism 100 - 4 .
