Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and in particular to an electronic device. Background Technology

[0002] With the rapid development of electronic devices, consumers generally desire larger screens to enhance video viewing experiences, while maintaining a compact size for easy portability. Consequently, an increasing number of electronic devices with foldable screens have been developed.

[0003] However, it has been found that existing electronic devices with foldable screens develop creases at the folding points as the number of folds increases. When the device is unfolded, the crease is located in the center of the screen, affecting the user experience. Summary of the Invention

[0004] This application provides an electronic device that displays images without creases on the screen, effectively improving the user experience.

[0005] This application provides an electronic device, which includes a screen assembly, a folding component, and a driving assembly.

[0006] The screen assembly includes a display screen, a first reel, and a second reel. The first reel and the second reel are respectively connected to both sides of the display screen along a first direction. A portion of the display screen is wound around the first reel and / or the second reel. The display screen has a first region and a second region arranged along the first direction.

[0007] The folding component includes a first housing and a second housing, which are rotatably connected to allow the electronic device to switch between an unfolded state and a folded state; the display screen is disposed on one side of the folding component, the first scroll is disposed inside the first housing, and the second scroll is disposed inside the second housing;

[0008] The driving component is connected to the folding member, the first scroll and the second scroll respectively. The driving component can drive the first scroll and the second scroll to rotate, and drive the display screen to reciprocate relative to the folding member along the first direction.

[0009] In the folded state, the second region corresponds to the connection between the first housing and the second housing and forms a bent region. In the unfolded state, the second region is rolled up and stored inside the first housing or the second housing.

[0010] The electronic device provided in this application embodiment has a display screen assembly comprising a first region and a second region. A driving component can drive a first scroll and a second scroll to reciprocate the display screen relative to a folding member along a first direction. When the electronic device is in a folded state, the connection between the second screen and the first and second housings corresponds to form a bent region in the second region. When the folding member is in an unfolded state, the second region is completely housed within the first or second housing to hide the bent region, allowing the first region to cover the folding member along a second direction, thus using the entire first region for image display. Therefore, when displaying images, since the second region forming the bent region is hidden within the first or second housing, the first region will not have creases, thereby improving the user experience.

It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to this application.

[0033] In the description of this application, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific situations.

[0034] As Figures 1 to 5 shown, an embodiment of this application provides an electronic device. Among them, the electronic device includes a screen assembly 1, a folding member 2, and a driving component 3.

[0035] The screen assembly 1 includes a display screen 11, a first reel 12, and a second reel 13. The first reel 12 and the second reel 13 are respectively connected to both sides of the display screen 11 along the first direction X, and a part of the display screen 11 is wound around the first reel 12 and / or the second reel 13. The display screen 11 has a first area 111 and a second area 112 arranged along the first direction X; the first area 111 is used for image display, and the second area 112 can be used for arranging circuits and at the same time expand the size of the display screen 11 in the first direction X.

[0036] The folding member 2 includes a first housing 21 and a second housing 22 arranged along the first direction X and rotationally connected. The screen assembly 1 is movably installed on the folding member 2; the first housing 21 and the second housing 22 rotate relative to each other to achieve folding or unfolding, so that the electronic device can switch between the unfolded state and the folded state. The position of the display screen 11 opposite to the rotationally connected part between the first housing 21 and the second housing 22 is bent during the folding of the folding assembly.

[0037] The drive assembly 3 is connected to the folding member 2, the first scroll 12 and the second scroll 13 respectively. The drive assembly 3 can drive the first scroll 12 and the second scroll 13 to rotate and drive the display screen 11 to reciprocate relative to the folding member 2 along the first direction X; so as to adjust the relative position between the display screen 11 and the folding member 2, so that when the folding member 2 is unfolded and when it is folded, the different positions of the display screen 11 correspond to the rotational contact points between the first housing 21 and the second housing 22.

[0038] In the folded state, the second region 112 corresponds to the connection between the first housing 21 and the second housing 22 and forms a bending region. In the unfolded state, the second region 112 is rolled up and stored inside the first housing 21 or the second housing 22 to hide the bending region.

[0039] Specifically, in the unfolded state, the first region 111 covers the folding member 2 along the second direction Y, and the entire first region 111 is used for image display. In the folded state, the display screen 11 moves relative to the folding member 2 along the first direction X, so that a part of the second region 112 and a part of the first region 111 cover the folding member 2 along the second direction Y, and the connection between the second region 112 and the first region 111 or the rotational connection between the second region 112 and the first housing 21 and the second housing 22 are opposite each other. Thus, in the folded state, the connection between the first region 111 and the second region 112 of the display screen 11 or the second region 112 is bent. Therefore, after the display screen 11 is folded many times over a long period of time, creases will be generated at the connection between the first region 111 and the second region 112 or in the second region 112, but not in the first region 111. This ensures that there are no creases when the first region 111 is used for image display, effectively improving the user experience.

[0040] Optionally, an angle is formed between the first direction X and the second direction Y.

[0041] Wherein, the first direction X and the second direction Y are perpendicular to each other. The first direction X is the left-right direction of the electronic device, and the second direction Y is the direction perpendicular to the display screen 11.

[0042] like Figure 3 As shown, this application embodiment provides an electronic device, wherein the display screen 11 includes a flexible display panel 113, a flexible circuit board 114 and a flexible substrate 115. The flexible display panel 113 is electrically connected to one side of the flexible circuit board 114 in the first direction X. The flexible substrate 115 covers the flexible display panel 113 and the flexible circuit board 114 along the second direction Y. A first region 111 is formed at the flexible display panel 113 and a second region 112 is formed at the flexible circuit board 114.

[0043] The flexible substrate 115 is used to protect the flexible display panel 113 and the flexible circuit board 114. It can be made of UTG (Ultra-Thin Glass) or CPI material and has good flexibility and light transmittance.

[0044] The flexible display panel 113 can be a flexible OLED (Organic Light-Emitting Diode) screen, and the flexible circuit board 114 is an FPC (Flexible Printed Circuit) circuit board.

[0045] like Figure 2 As shown in the embodiment of this application, the electronic device has a second region 112 whose size is greater than or equal to half the size of the first region 111 along the first direction X. This ensures that when the folding member 2 is in the folded state, the connection between the second region 112 and the first region 111, or the rotational connection between the second region 112 and the first housing 21 and the second housing 22, is opposite to each other. This ensures that creases in the display screen 11 are generated at the connection between the second region 112 and the first region 111, or in the second region 112, thereby preventing creases from forming in the first region 111.

[0046] Optionally, the size of the second region 112 along the first direction X is exactly half the size of the first region 111 along the first direction X. When the folding member 2 is in the folded state, the connection between the second region 112 and the first region 111 is opposite to the rotational contact point between the first housing 21 and the second housing 22, so that the crease is generated at the connection between the second region 112 and the first region 111. This can ensure that the crease is not generated in the first region 111, and at the same time reduce the size of the second region 112 along the first direction X, thereby reducing the manufacturing cost of the display screen 11.

[0047] like Figure 2 As shown in the embodiment of this application, the electronic device includes a first spool 12 rotatably mounted on the side of the first housing 21 away from the second housing 22, and a second spool 13 rotatably mounted on the side of the second housing 22 away from the first housing 21.

[0048] The side of the first region 111 away from the second region 112 is connected to the first scroll 12, and the side of the second region 112 away from the first region 111 is connected to the second scroll 13. When the folding member 2 is in the unfolded state, the first region 111 can be partially wound around the first scroll 12, or the first region 111 can only be connected to the first scroll 12 without being wound around the first scroll 12, and the second region 112 can be wound around the second scroll 13. The connection between the second region 112 and the first region 111 coincides with the projection of the edge of the second housing 22 away from the first housing 21 along the second direction Y, or the side of the first region 111 connected to the second region 112 is partially wound around the second scroll 13. Along the second direction Y, the portion of the projection of the first region 111 that falls into the projection of the folding member 2 is used for image display.

[0049] Optionally, when the folding member 2 is in the unfolded state, along the second direction Y, the projections of the two sides of the first region 111 along the first direction X coincide with the projections of the two sides of the folding member 2 along the first direction X, so as to minimize the size of the first region 111 along the first direction X, improve the utilization rate of the first region 111, and reduce the production cost of the first region 111.

[0050] When the folding member 2 is in the folded state, a portion of the first region 111 is wound around the first spool 12, and the surface of the second region 112 away from the first region 111 can be partially wound around the second spool 13 or only connected to the second spool 13, and the connection between the second region 112 and the first region 111 or the rotational connection between the second region 112 and the first housing 21 and the second housing 22 is opposite.

[0051] Optionally, when the folding member 2 switches between the unfolded state and the folded state, the first scroll 12 and the second scroll 13 rotate synchronously and in the same direction to drive the display screen 11 to reciprocate along the first direction X, and ensure that the display screen 11 is subjected to uniform force during the movement.

[0052] like Figure 5 and Figure 6 As shown in the embodiment of this application, the electronic device includes a first housing 21 comprising a first plate 211. The first plate 211 has a first hinge portion 212 and a second hinge portion 213 on the side facing the display screen 11 along the second direction Y. The first hinge portion 212 and the second hinge portion 213 are spaced apart along the first direction X. The first hinge portion 212 is located at the edge of the first housing 21 away from the second housing 22, and the second hinge portion 213 is located at the edge of the first housing 21 close to the second housing 22. The first scroll 12 is rotatably mounted on the first hinge portion 212, and the second hinge portion 213 is rotatably connected to the second housing 22.

[0053] The second housing 22 includes a second plate 221. The second plate 221 has a third hinge portion 222 and a fourth hinge portion 223 on the side facing the display screen 11. The third hinge portion 222 and the fourth hinge portion 223 are spaced apart along a first direction X. The third hinge portion 222 is located at the edge of the second housing 22 near the first housing 21, and the fourth hinge portion 223 is located at the edge of the second housing 22 away from the first housing 21. The second scroll 13 is rotatably mounted on the fourth hinge portion 223. The third hinge portion 222 and the second hinge portion 223 are rotatably connected.

[0054] The first hinge 212 is used to position and install the first scroll 12, and the fourth hinge 223 is used to position and install the second scroll 13. The second hinge 213 and the third hinge 222 realize the rotational connection between the first housing 21 and the second housing 22 on the one hand, and support the display screen 11 at the central position on the other hand, so as to ensure the flatness of the part of the display screen 11 opposite to the folding member 2 in the second direction Y.

[0055] like Figure 6 and Figure 7 As shown in the embodiment of this application, the electronic device includes a folding member 2 further comprising a hinge block 23. The hinge block 23 is disposed at at least one end of the second hinge portion 213 and the third hinge portion 222 in the third direction Z. Each hinge block 23 is rotatably connected to the second hinge portion 213 and the third hinge portion 222 respectively. The rotatable connection between the second hinge portion 213 and the third hinge portion 222 is realized through the hinge block 23, thereby realizing the rotatable connection between the first housing 21 and the second housing 22.

[0056] The angle between the plane defined by the first direction X and the second direction Y and the third direction Z is greater than 0 degrees.

[0057] Optionally, the third direction Z is perpendicular to the plane defined by the first direction X and the second direction Y, and the third direction Z is the up and down direction when the electronic device is assembled and used.

[0058] like Figure 6 and Figure 7 As shown in the embodiment of this application, the electronic device provided has two hinge blocks 23. The two hinge blocks 23 are respectively located at the two ends of the second hinge portion 213 and the third hinge portion 222 in the third direction Z. The hinge blocks 23 are provided with a first shaft hole 231 and a second shaft hole 232 that are spaced apart along the first direction X.

[0059] The folding component 2 also includes a first shaft 24 and a second shaft 25. The first shaft 24 passes through the first shaft hole 231 and the second hinge portion 213 of the two hinge blocks 23 along the third direction Z. The second shaft 25 passes through the second shaft hole 232 and the third hinge portion 222 of the two hinge blocks 23 along the third direction Z.

[0060] By setting two hinge blocks 23, the second hinge part 213 and the third hinge part 222 can be evenly stressed at both ends in the third direction Z when they rotate into contact, so as to ensure the stability of the first shell 21 and the second shell 22 when they rotate relative to each other.

[0061] Optionally, the portion of the first housing 21 located between the first hinge portion 212 and the second hinge portion 213, and the portion of the second housing 22 located between the third hinge portion 222 and the fourth hinge portion 223, can serve as a mounting platform for other electronic components in the electronic device, thereby improving the integration of the electronic device.

[0062] like Figure 10 and Figure 11 As shown in the embodiment of this application, the electronic device further includes a folding detection circuit. A resistor module 4 is connected in series in the folding detection circuit. During the relative rotation of the second hinge portion 213 and the third hinge portion 222, the resistance value of the resistor module 4 changes. By detecting the change in resistance value, the angle change between the first housing 21 and the second housing 22 is determined, thereby controlling the operation of the drive assembly 3 to drive the display screen 11 to reciprocate along the first direction X.

[0063] Optionally, the resistor module 4 includes a first resistor layer 41 and a second resistor layer 42. The first resistor layer 41 is attached to the second hinge portion 213, and the second resistor layer 42 is attached to the third hinge portion 222. The first resistor layer 41 and the second resistor layer 42 are in conductive contact.

[0064] The portion between the conductive contact point of the first resistive layer 41 and the second resistive layer 42 and the first end 411 of the first resistive layer 41, and the portion between the conductive contact point of the first resistive layer 41 and the first end 421 of the second resistive layer 42, are connected in series in the folding detection circuit.

[0065] During the relative rotation of the first hinge portion 212 and the second hinge portion 213, the distance between the position of the first resistive layer 41 and the second resistive layer 42 in conductive contact with the first end 411 of the first resistive layer 41 and the distance between the position of the first resistive layer 41 and the second resistive layer 42 in conductive contact with the first end 421 of the second resistive layer 42 increase or decrease synchronously.

[0066] That is, a portion of the first resistive layer 41 and a portion of the second resistive layer 42 are connected in series in the folding detection circuit. During the process of the folding member 2 switching from the folded state to the unfolded state, the portion of the first resistive layer 41 and the second resistive layer 42 connected in series gradually increases, and the resistance value generated by the first resistive layer 41 and the second resistive layer 42 connected in series gradually increases; during the process of the folding member 2 switching from the unfolded state to the folded state, the portion of the first resistive layer 41 and the second resistive layer 42 connected in series gradually decreases, and the resistance value generated by the first resistive layer 41 and the second resistive layer 42 connected in series gradually decreases.

[0067] By detecting the change in resistance value, the change in angle between the first housing 21 and the second housing 22 can be detected, thereby controlling the drive component 3 to drive the display screen 11 to reciprocate along the first direction X; and by detecting the speed of the change in resistance value, the speed of the change in angle between the first housing 21 and the second housing 22 can be detected, so as to control the direction and speed of the reciprocating movement of the display screen 11 along the first direction X through the drive component 3.

[0068] like Figure 2 and Figure 6 As shown in the embodiment of this application, the electronic device further includes a position detection component. The position detection component is connected to the display screen 11, the first housing 21, and the second housing 22, respectively. The position detection component can detect the relative positions of the first region 111 and the second region 112 with the folding member 2. By detecting the relative positions between the first region 111 and the second region 112 of the display screen 11 and the folding member 2, the position detection component can control the drive system to drive the display screen 11 to move or stop along the first direction X.

[0069] like Figure 2 and Figure 6 As shown in the embodiment of this application, the electronic device provided includes a position detection component comprising a sensing element 51, a first detection element 52, and a second detection element 53. The sensing element 51 is disposed in a first region 111, the first detection element 52 is mounted on a first housing 21, and the second detection element 53 is mounted on a second housing 22.

[0070] When the sensing element 51 is opposite to the first detection element 52 along the second direction Y, the first detection element 52 can detect the sensing element 51, and the connection between the second region 112 and the first region 111 or the rotational connection between the second region 112 and the first housing 21 and the second housing 22 is opposite. At this time, after the folding member 2 is folded, a crease will be generated at the connection between the second region 112 and the first region 111 or in the second region 112. When the sensing element 51 is opposite to the second detection element 53 along the second direction Y, the second detection element 53 can detect the sensing element 51, and the rotational connection between the first region 111 and the first housing 21 and the second housing 22 is opposite. At this time, the folding member 2 is in the unfolded state, and the first region 111 covers the folding member 2 along the second direction Y, which can be used for image display.

[0071] Optionally, the sensing element 51 is a magnet, and both the first detection element 52 and the second detection element 53 are Hall sensors.

[0072] Optionally, when the folding member 2 is in the folded state, the surface of the first scroll 12 away from the second hinge 213 is still covered by the first area 111, which can be used for image display, so that when the folding member 2 is in the folded state, a small screen is formed on its side to display time, weather or message notifications, etc.

[0073] like Figures 5 to 6 and Figures 8 to 9 As shown in the embodiment of this application, the electronic device includes a driving component 3 comprising a transmission component 31, a first driving component 32, and a second driving component 33. The transmission component 31 is fixedly connected to the display screen 11. The first driving component 32 is connected to the first scroll 12, the first shaft 24, and the first housing 21, respectively. The second driving component 33 is connected to the second scroll 13, the second shaft 25, and the second housing 22, respectively. The first driving component 32 and the second driving component 33 are respectively connected to the transmission component 31 in a transmission manner. The first driving component 32 and the second driving component 33 synchronously drive the transmission component 31 to move the display screen 11 back and forth along the first direction X.

[0074] Optionally, the transmission component 31 is a transmission belt, which is connected to at least one side of the display screen 11 along the third direction Z. The projection of the transmission belt along the third direction Z falls within the projection of the display screen 11. The dimension of the transmission belt in the first direction X is less than or equal to the dimension of the display screen 11 in the first direction X, and the dimension of the transmission belt in the second direction Y is less than or equal to the dimension of the display screen 11 in the second direction Y. This is to avoid the display screen 11 becoming uneven after being wound around the first reel 12 and / or the second reel 13 because the dimensions of the transmission belt along the first direction X and / or the second direction Y are greater than the dimensions of the display screen 11 in the first direction X and / or the second direction Y.

[0075] The first driving component 32 includes a first driving wheel 321 and a first driving motor 322. The first driving wheel 321 is connected to the first reel 12 and is also connected to the transmission belt. The first driving motor 322 is mounted on the first plate 211 and is connected to the first driving wheel 321. The first driving motor 322 can drive the first driving wheel 321 to rotate the first reel 12.

[0076] The second driving component 33 includes a fourth driving wheel 331 and a second driving motor 332. The fourth driving wheel 331 is connected to the second reel 13 and is also connected to the transmission belt. The second driving motor 332 is mounted on the second plate 221. The fourth driving wheel 331 is connected to the second driving motor 332. The second driving motor 332 can drive the fourth driving wheel 331 to rotate the second reel 13.

[0077] Optionally, the transmission belt has transmission teeth spaced along the first direction X on the side surface facing the folding member 2, and both the first drive wheel 321 and the fourth drive wheel 331 are gears, so as to reduce the situation where slippage occurs between the first drive wheel 321 and the transmission belt and between the fourth drive wheel 331 and the transmission belt during transmission, thus affecting the transmission efficiency.

[0078] like Figure 6 and Figure 9 As shown in the embodiment of this application, the electronic device provided includes a first driving component 32, which further includes a second driving wheel 323 connected to a first shaft 24 and connected to a transmission belt and a first driving motor 322 respectively; the second driving component 33 further includes a third driving wheel 333 connected to a second shaft 25 and connected to a transmission belt and a second driving motor 332 respectively.

[0079] The second drive wheel 323 and the third drive wheel 333 are also gears to ensure the transmission efficiency between the second drive wheel 323 and the transmission belt, and between the third drive wheel 333 and the transmission belt.

[0080] Optionally, both the first drive motor 322 and the second drive motor 332 are servo motors, and both the first drive motor 322 and the second drive motor 332 achieve steering transmission through worm gears.

[0081] The electronic device provided in this application embodiment includes a display screen 11 with transmission belts on both sides along the third direction Z; a first drive wheel 321 is located at one end of the first reel 12 along the third direction Z, and a first driven wheel 324 is located at the other end of the first reel 12 along the third direction Z; a second drive wheel 323 is located at one end of the first shaft 24 along the third direction Z, and a second driven wheel 325 is located at the other end of the first shaft 24 along the third direction Z; the first driven wheel 324 and the second driven wheel 325 are respectively connected to one of the transmission belts for transmission.

[0082] The third drive wheel 333 is located at one end of the second shaft 25 along the third direction Z, and the other end of the second shaft 25 along the third direction Z is provided with a third driven wheel 334; the fourth drive wheel 331 is located at one end of the second spool 13 along the third direction Z, and the other end of the second spool 13 along the third direction Z is provided with a fourth driven wheel 335; the third driven wheel 334 and the fourth driven wheel 335 are respectively connected to one of the transmission belts for transmission.

[0083] The first driven pulley 324, the second driven pulley 325, the third driven pulley 334, and the fourth driven pulley 335 can be connected to the same drive of the two drive belts, or they can be connected to either drive of the two drive belts.

[0084] By setting the first driven wheel 324, the second driven wheel 325, the third driven wheel 334 and the fourth driven wheel 335, they can cooperate with the first drive wheel 321, the second drive wheel 323, the third drive wheel 333 and the fourth drive wheel 331 to drive and support the display screen 11 from both sides along the third direction Z, so that the display screen 11 is evenly stressed during the reciprocating movement along the first direction X.

[0085] The electronic device provided in this application embodiment has a screen assembly with a display screen including a first region and a second region. A driving component can drive the display screen to reciprocate relative to a folding member along a first direction. When the folding member is in an unfolded state, the first region covers the folding member along a second direction, and the entire first region is used to display images. During the process of the folding member switching from an unfolded state to a folded state, the driving component drives the display screen to move along the first direction, so that the portion of the first region covering the folding member along the second direction gradually decreases and a portion of the second region covers the folding member along the second direction. When the folding member is in a folded state, the connection between the second region and the first region or the connection between the second region and the first and second housings are opposite each other. At this time, the folded position of the display screen is located at the connection between the second region and the first region or in the second region. Therefore, a crease will be formed at the connection between the second region and the first region or in the second region, but not in the first region. Therefore, when displaying images, there will be no crease in the first region, thereby improving the user experience.
