Description

Technical Field

[0001] This application relates to the field of electronic devices, and more specifically, to electronic devices and methods of using electronic devices. Background Technology

[0002] Electronic devices such as mobile phones combine portability and the need for a large screen through folding. Among the known technologies, there are bi-fold, tri-fold, and even quad-fold folding phones. As the number of foldable layers increases, these electronic devices can achieve a larger screen when unfolded.

[0003] However, excessive folding can make electronic devices too thick when folded, which negatively impacts the goal of making electronic devices thinner and lighter. Summary of the Invention

[0004] This application provides an electronic device and a method for using the electronic device to solve the problem that known electronic devices cannot effectively balance large-screen display and thinness.

[0005] In a first aspect, embodiments of this application provide an electronic device, including a housing assembly, a first screen, and a second screen. The housing assembly includes a first housing, a hinge assembly, and a second housing. The second housing includes a fixed housing and a sliding housing. The fixed housing is rotatably connected to the first housing via the hinge assembly, allowing the second housing and the first housing to be relatively flattened or folded. The sliding housing is slidably connected to the side of the fixed housing away from the hinge assembly, allowing the sliding housing and the fixed housing to be relatively unfolded or retracted. The first screen is a flexible screen. A portion of the first screen is disposed on the front side of the housing assembly, and another portion is rolled around from the side of the sliding housing away from the hinge assembly to the back side of the sliding housing. The first screen can be partially unfolded to the front side of the second housing or rolled to the back side of the second housing as the sliding housing slides relative to the fixed housing. The second screen is disposed on the back side of the first housing.

[0006] The electronic device described in this embodiment achieves a screen size close to that of a three-fold screen with a thickness approaching that of a two-fold fold, effectively satisfying both the demand for a large screen and the need for a slim and lightweight design. Furthermore, the first, second, and third states of this electronic device enable various different usage modes, resulting in a superior user experience.

[0007] In one possible implementation, the second housing further includes a connecting housing. The connecting housing is slidably connected to the back of the sliding housing, and one end of the first screen, which is rolled around to the back of the sliding housing, is fixedly connected to the connecting housing. The electronic device also includes a transmission mechanism disposed in the second housing, used to transmit the sliding motion of the sliding housing relative to the fixed housing to the connecting housing, thereby driving the connecting housing to slide relative to the sliding housing. The sliding amount of the connecting housing relative to the sliding housing is twice the sliding amount of the sliding housing relative to the fixed housing.

[0008] In this embodiment, the connecting shell can reliably fix the first screen, and by setting a transmission mechanism, the sliding amount of the connecting shell relative to the sliding shell can be twice the sliding amount of the sliding shell relative to the fixed shell, which is beneficial to enable the first screen to slide and unfold synchronously during the sliding shell rolling process. The structure is simple and reasonable.

[0009] In one possible implementation, the transmission mechanism includes a pulley and a rope. The pulley is disposed on the sliding housing, the rope passes around the pulley, and one end of the rope is connected to the fixed housing and the other end is connected to the connecting housing.

[0010] In this embodiment, the pulley is actually a movable pulley that slides together with the sliding housing. Furthermore, one end of the rope is fixed relative to the fixed housing, and the other end is connected to the connecting housing. Due to the nature of the movable pulley, the displacement of the end of the rope connected to the connecting housing is twice the displacement of the movable pulley. Therefore, this transmission mechanism has a simple structure and can accurately achieve twice the sliding distance of the first screen's rolling end without the need for an additional elastic tension structure, ensuring the smooth unfolding or retraction of the first screen.

[0011] In one possible implementation, one end of the rope is connected to a first buckle, and the other end is connected to a second buckle. The first buckle is connected to the fixed housing, and the second buckle is connected to the connecting housing.

[0012] In this embodiment, the first latch and the second latch can easily connect the fixed housing and the connecting housing.

[0013] In one possible implementation, the transmission mechanism includes a first pulley, a second pulley, a first latch, a second latch, and a rope. The first and second pulleys are connected to the sliding housing at intervals along the sliding direction of the sliding housing, and the rope is looped and wound between the first and second pulleys. The first latch is fixedly connected to the sliding housing, and the second latch is fixedly connected to the connecting housing.

[0014] In this embodiment, when the sliding housing slides relative to the fixed housing, since the first latch is fixed relative to the sliding housing, the second latch will slide the same distance relative to the sliding housing, thereby causing the connecting housing to slide by twice the amount.

[0015] In one possible implementation, the rope is wound around the first and second pulleys to form a synchronous pulley assembly. The rope includes a first wound section, a second wound section, a first intermediate section, and a second intermediate section, which are connected end-to-end in a loop. The first wound section is wound around the semicircle of the first pulley on the side opposite to the second pulley, and the second wound section is wound around the semicircle of the second pulley on the side opposite to the first pulley. The first and second intermediate sections are located between the first and second pulleys, respectively. A first latch is fixed to the first intermediate section, and a second latch is fixed to the second intermediate section. When the sliding housing and the fixed housing are in a relatively contracted state, the distance between the first latch and the second latch is twice the amount of sliding of the sliding housing, and the first latch is on the side of the second latch away from the fixed housing. When the sliding housing and the fixed housing are in a relatively unfolded state, the distance between the first latch and the second latch is twice the amount of sliding of the sliding housing, and the first latch is on the side of the second latch closer to the fixed housing.

[0016] In this embodiment, by using a first pulley and a second pulley to wind the looped rope, the rope is more reliably secured, and the forces on the first and second latches are more balanced. When the sliding housing slides relative to the fixed housing, because the first latch is fixed to the sliding housing, the second latch will slide the same distance relative to the sliding housing, thus causing the connecting housing to slip by twice the amount. This transmission mechanism has a simple structure and can accurately achieve twice the slip of the first screen's winding end without the need for an additional elastic tension structure, ensuring that the first screen can unfold or retract smoothly.

[0017] In one possible implementation, there are two transmission mechanisms, which are respectively located at both ends of the sliding housing along its length; wherein the length direction is perpendicular to the sliding direction of the sliding housing and also perpendicular to the thickness direction of the sliding housing.

[0018] In this embodiment, the two transmission mechanisms facilitate smooth transmission.

[0019] In one possible implementation, the electronic device further includes a drive assembly. The drive assembly is disposed in the fixed housing and is drively connected to the sliding housing, for driving the sliding housing to slide relative to the fixed housing.

[0020] In this embodiment, the drive component can easily drive the sliding housing, making operation convenient and labor-saving.

[0021] In one possible implementation, the drive assembly includes a motor, a gearbox, and a lead screw and slider mechanism; the lead screw and slider mechanism includes a lead screw and a slider; the slider is movably fitted to the lead screw. The motor is fixedly mounted on the fixed housing, and the motor is connected to the lead screw via the gearbox to drive the lead screw to rotate, thereby driving the slider to slide; the slider is fixedly connected to the sliding housing to drive the sliding housing to slide relative to the fixed housing.

[0022] In this embodiment, the drive assembly can conveniently and reliably drive the sliding housing, and the gearbox can achieve a greater driving force.

[0023] In one possible implementation, there are two sets of drive assemblies, located on opposite sides of the length of the second housing. The drive assemblies are arranged in an L-shape, wherein the lead screw and slider mechanism extends along the width of the second housing, forming one side of the L-shape, and the motor and gearbox are connected along the length of the second housing, forming the other side of the L-shape.

[0024] In this embodiment, there are two sets of drive components, which facilitates smooth sliding of the sliding housing. The L-shaped arrangement of the drive components is reasonable.

[0025] In one possible implementation, the fixed housing includes a first housing portion and a second housing portion, the first housing portion being rotatably connected to a rotating shaft assembly, and the second housing portion being connected to the side of the first housing portion away from the rotating shaft assembly. A sliding housing portion is slidably connected to the second housing portion and is capable of sliding to be fitted outside the second housing portion or partially sliding out of the second housing portion.

[0026] In this embodiment, the second shell portion of the fixed housing is used to cooperate with the sliding housing and can support the portion of the first screen. The first shell portion can serve as a separator between the second screen and the sliding screen area of ​​the first screen, which is conducive to the split-screen linkage use of the sliding screen areas of the second screen and the first screen.

[0027] In one possible implementation, the electronic device further includes a camera module. The camera module is disposed on the back of the first housing.

[0028] In this embodiment, the internal space of the first shell can be used to accommodate the camera module.

[0029] In one possible implementation, the two side surfaces of the second shell portion along the thickness direction are respectively recessed relative to the two side surfaces of the first shell portion along the thickness direction to form stepped spaces, which are used to accommodate the sliding shell. The width of the second shell portion accounts for 40-50% of the width of the second shell. The camera module has an outwardly protruding portion protruding from the back of the second shell portion; the width of the outwardly protruding portion accounts for 80-100% of the width of the second shell.

[0030] In this embodiment, a camera module with a larger width can be arranged, and the sliding screen area and the second screen can be separated by a greater distance to achieve dual-screen linkage in the form of physical split screen, which can make full use of the back space of the fixed housing.

[0031] In one possible implementation, the electronic device further includes a first circuit board. The first circuit board is disposed within a first housing, and the first circuit board and the camera module are arranged sequentially along the length of the first housing.

[0032] In this embodiment, the space of the first shell can be used to arrange the camera module and the first circuit board respectively, resulting in a reasonable structural arrangement.

[0033] In one possible implementation, the electronic device further includes one or more batteries disposed within a first housing and / or a second housing; and / or, the electronic device further includes one or more second circuit boards disposed within a first housing.

[0034] In this embodiment, the electronic device can arrange the battery and the second circuit board as needed, specifically according to the required arrangement.

[0035] In one possible implementation, the electronic device further includes a linkage mechanism located at the midpoint of the length direction of the second housing; the linkage mechanism extends along the width direction of the second housing, with one end connected to a fixed housing and the other end connected to a sliding housing.

[0036] In this embodiment, the linkage mechanism helps to improve the connection reliability of the fixed housing and the sliding housing, as well as the stability of the drive.

[0037] In one possible implementation, the hinge assembly is an inward-folding hinge assembly. The electronic device has a first state, a second state, and a third state. In the first state, the sliding housing and the fixed housing are relatively contracted, and the first housing and the second housing are folded relative to each other via the hinge assembly. The first screen is partially folded inside the first housing and the second housing, and partially exposed on the back of the fixed housing and opposite to the second screen. In the second state, the sliding housing and the fixed housing are relatively contracted, and the first housing and the second housing are relatively flattened relative to each other via the hinge assembly. The aspect ratio of the portion of the first screen located on the front of the first housing and the second housing is 1:1, and the portion of the first screen located on the back of the second housing is on the same plane as the second screen and spaced apart from it. In the third state, the first housing and the second housing are relatively flattened relative to each other via the hinge assembly, and the sliding housing and the fixed housing are relatively slid open relative to each other. The aspect ratio of the portion of the first screen located on the front of the first housing and the second housing is 2:3.

[0038] In this embodiment, the electronic device has multiple states and multiple usage modes, which can improve the user experience.

[0039] Secondly, embodiments of this application provide a method for using an electronic device, which is based on the aforementioned electronic device. The method for using the electronic device includes:

[0040] The electronic device has a first state, a second state, and a third state. In the first state, the sliding housing and the fixed housing are relatively retracted, the first housing and the second housing are folded relative to each other via a hinge assembly, the second screen is used as the main screen of the electronic device, and the sliding screen area of ​​the first screen is used for Always-On Display (AOD), wherein the sliding screen area refers to the portion of the first screen that slides down to the back of the second housing; and / or,

[0041] In the second state, the sliding housing and the fixed housing are relatively retracted, and the first housing and the second housing are relatively flattened through the pivot assembly. The portion of the first screen located on the front of the first and second housings is used as the main screen, and the second screen and the sliding screen area are used in conjunction; and / or,

[0043] The electronic device in this embodiment can be used in multiple states and multiple usage modes, which can improve the user experience.

[0044] In one possible implementation, in the first state, the Always-On Display (AOD) includes a clock mode for displaying the time or a mode for taking a selfie with the main camera; and / or,

[0113] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0114] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. When a component is said to be "set on" another component, it can be directly set on the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0115] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0116] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0117] Example

[0118] Foldable electronic devices, such as foldable phones, can typically be folded into two or three layers. In some known foldable phones, the aspect ratio (the ratio of the length to the width) of the screen panel (the dimension perpendicular to the thickness direction) carried by each layer is typically 18:9, 16:9, etc.

[0119] For a two-fold phone, the aspect ratio of the screen when unfolded is approximately 1:1. Due to the stacking layout, the thickness of each layer is approximately 4-6mm, and the total thickness of the two-fold phone when folded is approximately 8-12mm.

[0120] For a three-fold phone, the aspect ratio of the screen when unfolded is approximately 2:3. The total thickness of a three-fold phone when folded will reach 12-14mm, which is much thicker than that of a typical candybar phone. This is not conducive to making electronic devices thinner and lighter, and makes them inconvenient to carry and use.

[0121] In other words, due to the limitations of the stacking layout, known folding solutions have difficulty balancing the needs of large screens and thinness.

[0122] In view of this, embodiments of this application provide an electronic device 100. Taking a mobile phone as an example, the electronic device 100... Figures 1-10 The three different usage states of the electronic device 100 are shown. Figures 11-12 An exploded view shows the components of the electronic device 100.

[0123] The electronic device 100 in this embodiment may be, but is not limited to, a mobile phone, tablet computer, laptop computer, ultra-mobile personal computer (UMPC), handheld computer, touch screen TV, walkie-talkie, netbook, POS machine, personal digital assistant (PDA), wearable device, virtual reality device, and other fixed or mobile terminals.

[0124] In this embodiment, the electronic device 100 includes a housing assembly 3, a first screen 1, and a second screen 2.

[0125] In this embodiment, the first screen 1 can be a flexible screen, including but not limited to an organic light-emitting diode (OLED) display, an active-matrix organic light-emitting diode (AMOLED) display, a mini organic light-emitting diode (MLED) display, a microorganic light-emitting diode (MOLED) display, a micro organic light-emitting diode (MOLED) display, or a quantum dot light-emitting diode (QLED) display, etc.

[0126] The second screen 2 can be a rigid screen or a flexible screen.

[0127] The housing assembly 3 includes a first housing 10, a pivot assembly 30, and a second housing 20. The second housing 20 is rotatably connected to the first housing 10 via the pivot assembly 30, allowing the second housing 20 and the first housing 10 to be relatively flattened or folded. The second housing 20 includes a fixed housing 21 and a sliding housing 22. The fixed housing 21 is rotatably connected to the first housing 10 via the pivot assembly 30, allowing the second housing 20 and the first housing 10 to be relatively flattened or folded. The sliding housing 22 is slidably connected to the side of the fixed housing 21 away from the pivot assembly 30, allowing the sliding housing 22 and the fixed housing 21 to be relatively unfolded or retracted.

[0128] A portion of the first screen 1 is located on the front side S1 of the housing assembly 3, and another portion is rolled around from the side of the sliding housing 22 away from the pivot assembly 30 to the back side S2 of the sliding housing 22. The first screen 1 can be partially unfolded to the front side S1 of the second housing 20 or rolled up to the back side S2 of the second housing 20 as the sliding housing 22 slides relative to the fixed housing 21. The second screen 2 is located on the back side S2 of the first housing 10.

[0129] In this embodiment, the hinge assembly 30 can be an inward-folding hinge assembly. When folded, part of the first screen 1 is sandwiched between the first housing 10 and the second housing 20, and another part can be rolled from one side of the sliding housing 22 to the back side S2 of the sliding housing 22.

[0130] The electronic device 100 of this embodiment has a first state, a second state, and a third state.

[0131] Figure 1 This is a front view of the electronic device 100 in the first state according to this embodiment. Figure 2 for Figure 1 Rear view, Figure 3 for Figure 1 A bottom view.

[0132] like Figures 1-3 In the first state, the sliding housing 22 and the fixed housing 21 are relatively contracted, the first housing 10 and the second housing 20 are folded relative to each other through the pivot assembly 30, the first screen 1 is partially folded inside the first housing 10 and the second housing 20, and partially exposed on the back side S2 of the fixed housing 21 and opposite to the second screen 2.

[0133] In the first state, the second screen 2 can be used as the main screen of the electronic device 100, and the sliding screen area 12 of the first screen 1 is used for always-on display (AOD) (such as clock display, main camera selfie display, etc.). The sliding screen area 12 refers to the part of the first screen 1 that slides to the back S2 of the second housing 20.

[0134] In its first state, the electronic device 100 is roughly in a bi-fold configuration, and its total thickness is also close to the bi-fold thickness, for example, 8-12mm. The aspect ratio of the second screen 2 (i.e., perpendicular to the thickness) can be equal to or close to the dimensions of a typical candybar phone, such as 20:9, 18:9, or 16:9. At this time, the dimensions of the electronic device 100 in all directions are close to those of a typical candybar phone, and the user can use the second screen 2 as the main screen to operate the electronic device 100.

[0135] Figure 4 This is a front view of the electronic device 100 in the second state according to this embodiment. Figure 5 for Figure 4 Rear view, Figure 6 for Figure 4 A bottom view. Figure 7 for Figure 5 A diagram showing the result after rotating 90° counterclockwise.

[0136] like Figures 4-7 In the second state, the sliding housing 22 and the fixed housing 21 are relatively contracted, the first housing 10 and the second housing 20 are relatively flattened by the pivot assembly 30, the aspect ratio of the portion of the first screen 1 located on the front side S1 of the first housing 10 and the second housing 20 can be equal to or about 1:1, and the portion of the first screen 1 located on the back side S2 of the second housing 20 is on the same side as the second screen 2 and spaced apart from each other.

[0137] In the second state, the portion of the first screen 1 on the front surface S1 of the first housing 10 and the second housing 20 is used as the main screen, and the second screen 2 can be used in dual-screen linkage with the scrollable screen area 12 of the first screen 1.

[0138] Among them, the dual-screen linkage use can include a game mode, a competition viewing mode, a movie viewing mode, or other modes. At this time, it can be Figure 5 rotated counterclockwise by 90° to the state where the second screen 2 faces upward and the scrollable screen area 12 faces downward (see Figure 7 ) for use.

[0139] The game mode includes: displaying the game (such as a fighting game) screen on the second screen 2 and displaying virtual control keys on the scrollable screen area 12. The virtual control keys can be virtual joysticks, function keys, etc. used to control the progress of the game. The virtual joystick can be used to implement functions such as direction control in the game. The function keys can include common game control buttons such as direction keys, attack keys, etc.

[0140] The competition viewing mode includes: displaying the competition screen and score information on the second screen 2 and displaying relevant information about the competition on the scrollable screen area 12. The relevant information about the competition can be: substitute lineup, formation and tactical information, group points, real-time refreshed information on promotion situation, etc.

[0141] The movie viewing mode includes: displaying the movie screen on the second screen 2 and displaying relevant information about the movie on the scrollable screen area 12. The relevant information about the movie can be information related to the currently watched movie, such as a character relationship diagram, a plot line, collection of information about the murderer in a detective drama, AI recognition of items in the movie screen, etc.

[0143] As Figures 8-10 , in the third state, the first housing 10 and the second housing 20 are flattened relative to each other through the rotating shaft assembly 30, the sliding housing 22 and the fixed housing 21 slide and expand relative to each other, and the aspect ratio of the portion of the first screen 1 on the front surface S1 of the first housing 10 and the second housing 20 can be equal to or approximately 2:3.

[0144] In the third state, the portion of the first screen 1 on the front surface S1 of the first housing 10 and the second housing 20 is used as the main screen, and the second screen 2 is used as the secondary screen. For example, the main screen is used to implement the tablet movie viewing function, and the secondary screen is used for real-time preview and / or interaction function of the photo-taking screen.

[0145] The electronic device 100 of this embodiment can achieve a screen size close to that of a three-fold screen with a thickness close to that of a two-fold screen, thus effectively meeting both the requirements for a large screen and a thin and light design. Furthermore, the first, second, and third states of the electronic device 100 can realize a variety of different usage modes, resulting in a good user experience.

[0146] See also Figure 9 and Figure 10 In this embodiment, the fixed housing 21 includes a first housing portion 21a and a second housing portion 21b. The first housing portion 21a is rotatably connected to the rotating shaft assembly 30, and the second housing 20 is connected to the side of the first housing 10 away from the rotating shaft assembly 30. The sliding housing 22 is slidably connected to the second housing portion 21b and can slide to be fitted outside the second housing portion 21b or partially slide out of the second housing portion 21b.

[0147] The first shell 10 and the second shell 20 can be integrally formed. The two side surfaces of the second shell portion 21b along the thickness direction Z are respectively recessed relative to the two side surfaces of the first shell portion 21a along the thickness direction Z to form stepped spaces Q1. The stepped spaces Q1 are used to accommodate the sliding shell 22. In the contracted state, the two side surfaces of the sliding shell 22 along the thickness direction Z can be flush with the two side surfaces of the first shell portion 21a along the thickness direction Z, so that the first screen 1 can be supported relatively flat on the surfaces of the sliding shell 22 and the first shell portion 21a.

[0148] See also Figure 9 and Figure 10 In this embodiment, the electronic device 100 also includes a camera module 40, which is arranged on the back side S2 of the first housing 21a.

[0149] In the second state (see Figures 5-7 The first screen 1 can slide and roll with the sliding housing 22 to a position covering the second housing portion 21b of the fixed housing 21, without covering the first housing portion 21a where the camera module 40 is located. In this way, the second screen 2 exposed on the back S2 of the electronic device 100 and the sliding screen are separated by the first housing portion 21a where the camera module 40 is located, which can easily realize the various dual-screen linkage usage modes described above.

[0150] The camera module 40 has an outwardly protruding portion 41 that protrudes from the back surface S2 of the second housing portion 21b. The outwardly protruding portion 41 can be a part of the decorative panel of the camera module 40. To improve the appearance effect and arrange more cameras, sensors, etc., the outwardly protruding portion 41 of the decorative panel needs to have a relatively large size. For example, in this embodiment, the width of the second housing portion 21b accounts for 40 - 50% of the width of the second housing 20, and the width of the outwardly protruding portion 41 accounts for 80 - 100% of the width of the second housing 20. In this way, a camera module 40 with a relatively large width can be arranged, and the scrollable screen area 12 and the second screen 2 can be separated relatively far to achieve dual-screen linked use in a physically split-screen form.

[0151] Figure 11 For Figure 6 exploded view of; Figure 12 For Figure 11 partial enlarged view of; Figure 13 is a comparison diagram of the sliding housing 22 in the contracted state and the deployed state.

[0152] See Figures 11-13 Referring to , in this embodiment, the second housing 20 further includes a connecting housing 23. The connecting housing 23 is slidably connected to the back surface S2 of the sliding housing 22. The first screen 1 is wound around to one end (defined as the scroll end 11) of the back surface S2 of the sliding housing 22 and fixedly connected to the connecting housing 23. The electronic device 100 further includes a transmission mechanism 50. The transmission mechanism 50 is disposed in the second housing 20 and is used to transmit the sliding of the sliding housing 22 relative to the fixed housing 21 to the connecting housing 23 to drive the connecting housing 23 to slide relative to the sliding housing 22. Among them, the sliding amount of the connecting housing 23 relative to the sliding housing 22 is twice the sliding amount of the sliding housing 22 relative to the fixed housing 21.

[0153] Among them, the connecting housing 23 is generally a strip-shaped structure, and the scroll end 11 of the first screen 1 is fixedly connected to the connecting housing 23. For example, the scroll end 11 is fixedly connected to the connecting housing 23 by bonding or other connection forms. In this way, when the sliding housing 22 slides relative to the fixed housing 21, its sliding can be transmitted to the connecting housing 23 through the transmission mechanism 50, and then the scroll end 11 of the first screen 1 can be driven by the connecting housing 23 to slide relative to the sliding housing 22.

[0154] See Figure 13 Referring to , when the sliding amount of the sliding housing 22 relative to the fixed housing 21 is d1 (for example, 50 mm), the scroll end 11 of the first screen 1 also slides relative to the sliding housing 22, so that the sliding amount of the scroll end 11 relative to the fixed housing 21 is 2 * d1 (for example, 100 mm), ensuring that the first screen 1 can be smoothly deployed or wound up during the scrolling process.

[0155] Continue to refer to Figures 11-13In this embodiment, the transmission mechanism 50 includes a pulley 51 and a rope 52. The pulley 51 is disposed on the sliding housing 22, the rope 52 passes around the pulley 51, and one end of the rope 52 is connected to the fixed housing 21 and the other end is connected to the connecting housing 23.

[0156] In this embodiment, the pulley 51 is actually a movable pulley that slides together with the sliding housing 22. Furthermore, one end of the rope 52 is fixed relative to the fixed housing 21, and the other end is connected to the connecting housing 23. Based on the properties of the movable pulley, the displacement of the end of the rope 52 connected to the connecting housing 23 is twice the displacement of the movable pulley. Therefore, the transmission mechanism 50 has a simple structure and can accurately achieve twice the sliding distance of the sliding end 11 of the first screen 1 without the need for an additional elastic tension structure, ensuring that the first screen 1 can smoothly unfold or retract.

[0157] Optionally, one end of the rope 52 is connected to a first buckle 53 and the other end is connected to a second buckle 54. The first buckle 53 is connected to the fixed housing 21 and the second buckle 54 is connected to the connecting housing 23.

[0158] The specific structures of the first latch 53 and the second latch 54 can be configured as needed. The first latch 53 can be connected to the fixed housing 21 by snap-fit, screw connection, adhesive bonding, or other connection methods. Similarly, the second latch 54 can be connected to the connecting housing 23 by snap-fit, screw connection, adhesive bonding, or other connection methods.

[0159] Figure 14 Another transmission mechanism 50a of this embodiment is shown, which can also amplify and transmit the sliding amount of the sliding housing 22 to the sliding end 11 of the first screen 1, so that the sliding end 11 slides twice as much. Figure 15 To adopt Figure 14 A comparison diagram of the sliding housing 22 of the transmission mechanism 50a and the electronic device 100 in the retracted and extended states.

[0160] See Figures 14-15 The transmission mechanism 50a includes a first pulley 51a, a second pulley 51b, a first latch 53, a second latch 54, and a rope 55. The first pulley 51a and the second pulley 51b are connected to the sliding housing 22 at intervals along the sliding direction of the sliding housing 22. The rope 55 is looped and wound between the first pulley 51a and the second pulley 51b. The first latch 53 is fixedly connected to the sliding housing 22, and the second latch 54 is fixedly connected to the connecting housing 23.

[0161] In this embodiment, the rope 55 is wound around the first pulley 51a and the second pulley 51b. The first pulley 51a and the second pulley 51b have the same diameter to form a synchronous pulley assembly. The rope 55 includes a first winding section 55a, a second winding section 55b, a first intermediate section 55c, and a second intermediate section 55d, which are connected end to end in a loop. The first winding section 55a is wound around the semicircle of the first pulley 51a on the side opposite to the second pulley 51b, and the second winding section 55b is wound around the semicircle of the second pulley 51b on the side opposite to the first pulley 51a. The first intermediate section 55c and the second intermediate section 55d are located between the first pulley 51a and the second pulley 51b, respectively. A first locking buckle 53 is fixed to the first intermediate section 55c, and a second locking buckle 54 is fixed to the second intermediate section 55d.

[0162] When the sliding housing 22 and the fixed housing 21 are in a relatively retracted state, the distance between the first latch 53 and the second latch 54 is twice the amount of sliding of the sliding housing 22, and the first latch 53 is on the side of the second latch 54 away from the fixed housing 21.

[0163] When the sliding housing 22 and the fixed housing 21 are in a relatively unfolded state, the distance between the first latch 53 and the second latch 54 is twice the amount of sliding of the sliding housing 22, and the first latch 53 is on the side of the second latch 54 closer to the fixed housing 21.

[0164] In this transmission mechanism 50a, the annular rope 55 is wound around by first pulley 51a and second pulley 51b, making the rope 55 more reliably fixed and the forces on the first latch 53 and second latch 54 more balanced. When the sliding housing 22 slides relative to the fixed housing 21, since the first latch 53 is relatively fixed to the sliding housing 22, the second latch 54 will slide the same distance relative to the sliding housing 22, thereby causing the connecting housing 23 to slide by twice the amount. This transmission mechanism 50a has a simple structure and can accurately achieve twice the sliding amount of the sliding end 11 of the first screen 1 without the need for an additional elastic tension structure, ensuring that the first screen 1 can be smoothly unfolded or retracted.

[0165] In this embodiment, optionally, there are two transmission mechanisms 50, 50a, which are respectively located at both ends of the sliding housing 22 along the length Y direction; wherein the length Y direction is perpendicular to the sliding direction of the sliding housing 22 and perpendicular to the thickness Z direction of the sliding housing 22. The sliding direction of the sliding housing 22 is parallel to the width X direction of the sliding housing 22.

[0166] Figure 16 The internal stacking scheme of the electronic device 100 in this embodiment is shown, specifically in... Figure 5The arrangement of the drive components 60, circuit boards, battery 93, etc. inside the electronic device 100 is shown in dashed lines.

[0167] See Figure 16 The electronic device 100 also includes a drive assembly 60. The drive assembly 60 is disposed on the fixed housing 21 and is connected to the sliding housing 22 for driving the sliding housing 22 to slide relative to the fixed housing 21.

[0168] The drive component 60 can be controlled by a physical button on the electronic device 100. For example, a physical button is provided on the electronic device 100. When the user presses the physical button, the drive component 60 can be controlled to operate, so that the sliding housing 22 slides out relative to the fixed housing 21 or slides in the opposite direction to retract.

[0169] The drive component 60 can also be controlled by virtual buttons, for example, virtual buttons can be arranged on the first screen 1 or the second screen 2. When the virtual button is clicked, the drive component 60 is driven to operate in order to control the sliding housing 22 to slide.

[0170] In other embodiments, the sliding housing 22 may also be driven by other types of drive components.

[0171] In other embodiments, the sliding housing 22 can also be slid by manual pulling without the drive assembly 60.

[0172] In this embodiment, optionally, the drive assembly 60 includes a motor 61, a gearbox 62, and a lead screw and slider mechanism 63. The lead screw and slider mechanism 63 includes a lead screw 63a and a slider 63b; the slider 63b is movably fitted to the lead screw 63a. The motor 61 is fixedly mounted on the fixed housing 21, and the motor 61 is driven by the lead screw 63a through the gearbox 62 to rotate the lead screw 63a, thereby driving the slider 63b to slide; the slider 63b is fixedly connected to the sliding housing 22 to drive the sliding housing 22 to slide relative to the fixed housing 21. The slider 63b can be integrally mounted with the sliding housing 22 or separately mounted.

[0173] There are two sets of drive assemblies 60, located on opposite sides of the length Y direction of the second housing 20. The drive assemblies 60 are arranged in an L-shape, wherein the lead screw and slider mechanism 63 extends along the width X direction of the second housing 20, forming one side of the L-shape, and the motor 61 and gearbox 62 are connected along the length Y direction of the second housing 20, forming the other side of the L-shape.

[0174] In this embodiment, the motor 61 can be a brushless DC motor (BLDC) with a diameter of approximately 4mm. The gearbox 62 has a reduction ratio of 60, so the motor 61 can output a driving force of 30-40N after reduction by the gearbox 62, which can reliably realize the sliding of the sliding housing 22 relative to the fixed housing 21. This allows for a smaller thickness space while ensuring the driving force of the drive component 60, which is beneficial for the thinning and lightening of the electronic device 100.

[0175] There are two transmission mechanisms 50, 50a, located along the length Y of the second housing 20, with the two transmission mechanisms 50 located on the outer sides of the drive assembly 60 on both sides.

[0176] See also Figure 16 The electronic device 100 also includes a first circuit board 91. The first circuit board 91 is disposed within the first housing portion 21a, and the first circuit board 91 and the camera module 40 are arranged sequentially along the length direction Y of the first housing portion 21a. In this embodiment, the first housing portion 21a has a large thickness, and a large space can be provided inside it to arrange the first circuit board 91.

[0177] Optionally, the motor 61 and gearbox 62 of the drive assembly 60 can be arranged inside the first housing 21a. Since the first housing 21a has a larger thickness than the second housing 21b, it can accommodate a motor 61 with a larger thickness. The motor 61 with a larger thickness can provide greater driving force, which is beneficial for reliably driving the sliding housing 22 to roll.

[0178] The second housing 20 also contains a battery 93, which can be arranged inside the second housing portion 21b of the fixed housing 21.

[0179] The electronic device 100 has a compact and reasonable arrangement of the battery 93, the first circuit board 91, the drive component 60, the transmission mechanism 50, etc. in the internal space of the second housing 20, with high space utilization.

[0180] See also Figure 16 The electronic device 100 also includes a receiver 95 (RCV), a sound cavity assembly 96 (BOX), a battery 93, and one or more second circuit boards 92 respectively disposed in the first housing 10.

[0181] Inside the first housing 10, the battery 93 is located at the middle position in the length direction Y of the first housing 10. A second circuit board 92 and a sound cavity assembly 96 are provided at one end of the length direction Y of the battery 93, and another second circuit board 92 and a receiver 95 are provided at the other end.

[0182] The electronic device 100 has a reasonable arrangement of components within its first housing 10, resulting in high space utilization.

[0183] Figure 17 Another internal stacking scheme for electronic device 100a is shown.

[0184] See Figure 17 The electronic device 100a is in Figure 16 Based on the electronic device 100, the battery 93 inside the second housing 21b is divided into two smaller batteries 93 separated along the length direction Y. A linkage mechanism 94 is provided in the space between the two smaller batteries 93. The linkage mechanism 94 is located at the middle position of the second housing 21b along the length direction Y, and extends along the width direction X of the second housing 21b, with one end connected to the fixed housing 21 and the other end connected to the sliding housing 22. This linkage mechanism 94 can be a multi-link mechanism to improve the connection reliability and driving stability of the fixed housing 21 and the sliding housing 22.

[0185] Figure 18 Another internal stacking scheme for electronic device 100b is shown.

[0186] The electronic device 100b is in Figure 17 Based on the electronic device 100a, some adjustments were made to the arrangement of the components inside the first housing 10.

[0187] See Figure 18 Inside the first housing 10 of the electronic device 100, a battery 93 and a second circuit board 92 are spaced apart along the width direction X, and a sound cavity assembly 96 and a receiver 95 are respectively arranged at both ends of the battery 93.
