[0031] Combine the following Figure 1-Figure 15 An electronic device according to an embodiment of the present application is described.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, an electronic device according to some embodiments of the present application includes: a first shell 1, on which a first support plate 10 is provided; a second shell 2, which can slide relative to the first shell 1 so that the electronic device is in an expanded state and a contracted state, and on which a second support plate 20 is provided; a flexible screen 3, which covers the first shell 1 and the second shell 2; a third support plate 4, which is movably connected to the first shell 1 and the second shell 2; in the contracted state, the third support plate 4 is stored at the bottom of the second support plate 20, and the flexible screen 3 covers the first support plate 10 and the second support plate 20; in the expanded state, the third support plate 4 is located between the first support plate 10 and the second support plate 20, and the flexible screen 3 covers the first support plate 10, the third support plate 4 and the second support plate 20.

[0033] In the embodiment of the present application, the flexible screen 3 covers the first shell 1 and the second shell 2, and the second shell 2 can slide relative to the first shell 1, thereby realizing the enlargement or reduction of the display part of the flexible screen 3, so that the electronic device is in an expanded state or a contracted state, and the large screen function of the electronic device is realized while facilitating the carrying of the electronic device. A first support plate 10 is provided on the first shell 1, and a second support plate 20 is provided on the second shell 2. When the electronic device is in a contracted state, the flexible screen 3 covers the first support plate 10 and the second support plate 20, and the third support plate 4 is located at the bottom of the second support plate 20, so that the third support plate 4 is stored; when the electronic device is in an expanded state, the third support plate 4 is located between the first support plate 10 and the second support plate 20, and then the third support plate 4 can be supported at the gap between the first support plate 10 and the second support plate 20, so as to prevent the flexible screen 3 from collapsing after being pressed at the gap between the first support plate 10 and the second support plate 20.

[0034] It is understandable that if Figure 4 and Figure 5 As shown, in the retracted state, the first support plate 10 and the second support plate 20 are combined to support the flexible screen 3, which reduces the display area of ​​the electronic device to facilitate the portability of the electronic device; Figure 6 and Figure 7 As shown, when switching to the unfolded state, the second shell 2 slides relative to the first shell 1, so that the flexible screen 3 is unfolded, and the third support plate 4 moves between the first support plate 10 and the second support plate 20, so that the first support plate 10, the third support plate 4 and the second support plate 20 are spliced ​​to support the flexible screen 3, thereby increasing the display area of ​​the electronic device, and thereby preventing the flexible screen 3 from collapsing in the gap between the first support plate 10 and the second support plate 20.

[0035] According to some embodiments of the present application, the electronic device also includes: a linkage part, which is connected to the first shell 1, the second shell 2 and the third support plate 4, and is used to drive the third support plate 4 to extend between the first support plate 10 and the second support plate 20, or to drive the third support plate 4 to be stored at the bottom of the second support plate 20.

[0036] In this embodiment, the electronic device also includes a linkage part, which is connected to the first shell 1, the second shell 2 and the third support plate 4. During the movement of the second shell 2 relative to the first shell 1, the third support plate 4 is driven by the linkage part to move between the first support plate 10 and the second support plate 20, or to the bottom of the second support plate 20, thereby ensuring the reliability of the extension and retraction of the electronic device and providing sufficient support area for the flexible screen 3 in the unfolded state to prevent the flexible screen 3 from collapsing.

[0037] like Figure 8 and Fig. 9As shown, according to some embodiments of the present application, the linkage portion includes: a first track 12, which is arranged at an end of the first shell 1, and the first track 12 extends along the first direction; a second track 22, which is arranged at an end of the second shell 2, and the second track 22 extends along the second direction, and along the third direction, the first track 12 and the second track 22 are correspondingly arranged, and the second track 22 is inclined relative to the first direction; a connecting member 40, which is connected to the third support plate 4, and the connecting member 40 is located in the first track 12 and the second track 22, and can slide in the first track 12 along the first direction, and slide in the second track 22 along the second direction, wherein, along the second direction, a portion of the second shell 2 is located in the first shell 1.

[0038] In this embodiment, the linkage part includes a first track 12, a second track 22 and a connecting member 40. The first track 12 is arranged at the end of the first shell 1, and the second track 22 is arranged at the end of the second shell 2. The first track 12 extends along the first direction, and the second track 22 extends along the second direction. The first track 12 and the second track 22 are correspondingly arranged along the third direction. The connecting member 40 is arranged on the third support plate 4, is located in the first track 12 and the second track 22 and can slide in the first track 12 and the second track 22. In this way, when the second shell 2 slides relative to the first shell 1, the second shell 2 drives the connecting member 40 to slide in the second track 22 along the second direction. Since the connecting member 40 is simultaneously penetrated in the first track 12 and the second track 22, and the second track 22 is inclined relative to the first direction, under the joint action of the first track 12 and the second track 22, the connecting member 40 moves along the first direction, thereby realizing the lifting and lowering of the third support plate 4 along the third direction.

[0039] It can be understood that a portion of the second shell 2 along the second direction is located inside the first shell 1, the first track 12 is located in the portion of the first shell 1 covered outside the second shell 2, and the second track 22 is arranged in the portion of the second shell 2 located inside the first shell 1, so that the first track 12 and the second track 22 can be arranged correspondingly along the third direction, thereby realizing the lifting and lowering of the connecting member 40 in the first direction.

[0040] In a specific application, the first direction is the thickness direction of the electronic device, the second direction is the width direction of the electronic device, that is, the sliding direction of the second housing 2, and the third direction is the length direction of the electronic device. The first direction, the second direction and the third direction are perpendicular to each other.

[0041] like Fig. 9 As shown, according to some embodiments of the present application, from an end of the second shell 2 close to the first shell 1 to an end of the second shell 2 away from the first shell 1 , the second track 22 is inclined in a direction away from the second support plate 20 .

[0042] In this embodiment, along the second direction, from one end of the second shell 2 close to the first shell 1 to the end of the second shell 2 away from the first shell 1, the second track 22 extends in a direction away from the second support plate 20, so that when the second shell 2 slides in a direction away from the first shell 1 to unfold the electronic device, the connector 40 can move along the first direction toward the second support plate 20 under the action of the second track 22 and the first track 12, so that when the electronic device is unfolded, the third support plate 4 can move between the first support plate 10 and the second support plate 20 to support the flexible screen 3; accordingly, when the second shell 2 slides in a direction close to the first shell 1 to shrink the electronic device, the connector 40 can move along the first direction away from the second support plate 20 under the action of the second track 22 and the first track 12, so as to avoid the second support plate 20, so that the second support plate 20 and the first support plate 10 are combined to support the flexible screen 3, and at the same time, the third support plate 4 is stored at the bottom of the second support plate 20.

[0043] According to some embodiments of the present application, along the third direction, at least two first rails 12 are provided at both ends of the first shell 1, at least two second rails 22 are provided at both ends of the second shell 2, and at least two connecting members 40 are provided at both ends of the third support plate 4, and the first rails 12, the second rails 22 and the connecting members 40 are arranged in a one-to-one correspondence.

[0044] In this embodiment, along the third direction, at least two first tracks 12 are provided at both ends of the first shell 1, at least two second tracks 22 are provided at both ends of the second shell 2, and at least two connecting members 40 are provided at both ends of the third support plate 4. That is, both ends of the third support plate 4 are lifted and lowered in the first direction through the connecting members 40, thereby improving the stability of the third support plate 4 moving along the first direction.

[0045] In a specific application, along the third direction, the first end of the first shell 1 is provided with two first tracks 12, and the two first tracks 12 are distributed along the second direction, and the second end of the first shell 1 is provided with two first tracks 12, and the two first tracks 12 are distributed along the second direction; along the third direction, the first end of the second shell 2 is provided with two second tracks 22, and the two second tracks 22 are respectively arranged corresponding to the two first tracks 12 at the first end of the first shell 1, and the second end of the second shell 2 is provided with two second tracks 22, and the two second tracks 22 are respectively arranged corresponding to the two first tracks 12 at the second end of the first shell 1; along the third direction, the first end of the third support plate 4 is provided with two connecting members 40, and the two connecting members 40 are respectively inserted into the corresponding first tracks 12 and the second tracks 22, thereby improving the reliability of the movement of the third support plate 4.

[0046] like Fig.10 As shown, according to some embodiments of the present application, the flexible screen 3 includes a display area 30 and an extension area 32 that are connected to each other, the display area 30 covers the first shell 1 and the second shell 2, the extension area 32 is bent and arranged in the second shell 2, and is located on the side of the second support plate 20 away from the display area 30.

[0047] In this embodiment, the flexible screen 3 includes a display area 30 and an extension area 32. The display area 30 covers the first shell 1 and the second shell 2. The electronic device displays through the display area 30. The extension area 32 is connected to the display area 30 and is bent and arranged in the second shell 2, which increases the length of the extension area 32. When the electronic device is unfolded, the extension area 32 can be extended to the surface of the electronic device to form the display area 30 for the electronic device to display. When the electronic device is retracted, a part of the display area 30 is stored in the second shell 2 to form the extension area 32, so that the size of the display area 30 is changed during the unfolding and storage of the electronic device. It can be understood that in the process of switching between the unfolded state and the retracted state, the area of ​​the display area 30 is changed by the extension or contraction of the extension area 32. When the electronic device is unfolded, the extension area 32 stored in the second shell 2 extends to the position of the display area 30 and forms the display area 30 for display. When the electronic device is retracted, a part of the display area 30 is retracted into the second shell 2 to form the extension area 32 stored in the second shell 2.

[0048] When the electronic device is in a retracted state, the display area 30 is supported by the first support plate 10 and the second support plate 20, and when the electronic device is in an expanded state, the display area 30 is supported by the first support plate 10, the third support plate 4 and the second support plate 20, that is, the area of ​​the display area 30 in the retracted state is smaller than the area of ​​the display area 30 in the expanded state, and accordingly, the area of ​​the extension area 32 in the retracted state is larger than the area of ​​the extension area 32 in the expanded state.

[0049] like Fig.10 , Fig.11 and Fig.12As shown, according to some embodiments of the present application, the electronic device also includes: a first rotating shaft 5 and a second rotating shaft 6, the first rotating shaft 5 and the second rotating shaft 6 are rotatably connected to the second shell 2 and extend along the third direction of the electronic device, along the second direction of the electronic device, the first rotating shaft 5 is located at the first end of the second shell 2, the second rotating shaft 6 is close to the second end of the second shell 2, and along the first direction of the electronic device, the second rotating shaft 6 is located below the first rotating shaft 5; the extension area 32 bypasses the first rotating shaft 5 and the second rotating shaft 6 in sequence, so that the first rotating shaft 5 contacts the first surface 34 of the extension area 32, and the second rotating shaft 6 contacts the second surface 36 of the extension area 32, and the first surface 34 and the second surface 36 are two surfaces arranged opposite to each other.

[0050] In this embodiment, the electronic device also includes a first rotating shaft 5 and a second rotating shaft 6, both of which extend along a third direction. Along the second direction of the electronic device, the first rotating shaft 5 is located at the first end of the second shell 2, and the second rotating shaft 6 is close to the second end of the second shell 2. Along the first direction, the second rotating shaft 6 is located below the first rotating shaft 5. After the extension area 32 bypasses the first rotating shaft 5 from the second end of the second shell 2, it extends toward the second rotating shaft 6 and bypasses the second rotating shaft 6. The first rotating shaft 5 contacts the first surface 34 of the extension area 32, and the second rotating shaft 6 contacts the second surface 36 of the extension area 32, so that the first rotating shaft 5 and the second rotating shaft 6 can support the extension area 32 and make the extension area 32 bent.

[0051] The display area 30 and the extension area 32 are both connected to the first shell 1, that is, both ends of the flexible screen 3 are fixed on the first shell 1, so that when the electronic device is unfolded, the second shell 2 drives the first rotating shaft 5 and the second rotating shaft 6 to move, and the flexible screen 3 rotates the first rotating shaft 5 and the second rotating shaft 6 through friction, so that the display screen is always in a taut state. When the electronic device is contracted, the flexible screen 3 drives the first rotating shaft 5 and the second rotating shaft 6 to move through friction, so that the flexible screen 3 is in a taut state, thereby preventing the flexible screen 3 from wrinkling.

[0052] like Fig.10 and Fig.11 As shown, according to some embodiments of the present application, the electronic device also includes: a third rotation axis 7, which is arranged at one end of the first shell 1 away from the second shell 2, and the display area 30 is connected to the third rotation axis 7; a fourth rotation axis 8, which is arranged on the first shell 1, along the second direction, the fourth rotation axis 8 is located between the first rotation axis 5 and the second rotation axis 6, along the first direction, the fourth rotation axis 8 is located below the second rotation axis 6, and the end of the extension area 32 is wrapped around the fourth rotation axis 8.

[0054] Furthermore, the third rotating shaft 7 and the fourth rotating shaft 8 are fixed on the first housing 1 .

[0055] It can be understood that the third rotating shaft 7 and the fourth rotating shaft 8 are used to fix the two ends of the flexible screen 3, and the first rotating shaft 5 and the second rotating shaft 6 are used to make the flexible screen 3 taut.

[0070] In a specific application, the electronic device includes a first housing 1, a second housing 2, a flexible screen 3, a first support plate 10, a second support plate 20, a third support plate 4, a first rotating shaft 5, a second rotating shaft 6, a third rotating shaft 7, a fourth rotating shaft 8 and a driving unit 9. The two ends of the flexible screen 3 are respectively connected to the third rotating shaft 7 and the fourth rotating shaft 8. Among them, the first housing 1 includes a fixed shell 14 and a fixed bracket 16, and the second housing 2 includes a movable shell 24 and a movable bracket 26.

[0071] The driving part 9 drives the mobile bracket 26 to translate when it rotates. During the unfolding process of the flexible screen 3, the first rotating shaft 5 and the second rotating shaft 6 are rotated by the friction between the flexible screen 3 and the first rotating shaft 5 and the second rotating shaft 6, so that the flexible screen 3 is always in a taut state. The third support plate 4 is fixed in the second track 22 of the mobile bracket 26. During the movement, the third support plate 4 is raised to support the flexible screen 3 to prevent the flexible screen 3 from being pressed down.

[0072] Specifically, the flexible screen 3 is tightened by the first rotating shaft 5 and the second rotating shaft 6, the third rotating shaft 7 and the fourth rotating shaft 8 at the end of the flexible screen 3 are assembled to the fixed bracket 16, the first rotating shaft 5 and the second rotating shaft 6 are assembled to the movable bracket 26, the first supporting plate 10, the second supporting plate 20 and the third supporting plate 4 are placed under the flexible screen 3, when the screen becomes larger, the first rotating shaft 5 and the second rotating shaft 6 are rotated by the friction between the flexible screen 3 and the first rotating shaft 5 and the second rotating shaft 6 during the unfolding process of the flexible screen 3, so that the flexible screen 3 is always in a tightened state. The third supporting plate 4 will rise to the same plane as the first supporting plate 10 and the second supporting plate 20, and play the role of supporting the flexible screen 3 to prevent it from sinking.

[0073] Furthermore, two groups of motors 90 are fixed on the fixing bracket 16, and there is a driving unit 9 at the head and tail of the electronic device, so that the forces on the head and tail sides are balanced when the electronic device is unfolded.

[0074] Among them, a rack 94 is provided on the mobile bracket 26, and the motor 90 rotates and meshes with the rack 94 to drive the mobile bracket 26 to realize linear reciprocating motion. The first rotating shaft 5 and the second rotating shaft 6 are sleeved on the corresponding holes of the mobile bracket 26. During the unfolding process of the flexible screen 3, the friction between the flexible screen 3 and the first rotating shaft 5 and the second rotating shaft 6 causes the first rotating shaft 5 and the second rotating shaft 6 to rotate, so that the flexible screen 3 is always in a taut state. The third support plate 4 is below the second support plate 20, the first support plate 10 is fixed on the fixed bracket 16, and the second support plate 20 is fixed on the mobile bracket 26 and can move horizontally therewith.

[0075] Furthermore, the third support plate 4 is firstly sleeved in the second track 22 arranged obliquely on the movable bracket 26 , passes through the second track 22 and is simultaneously sleeved in the first track 12 arranged vertically on the fixed bracket 16 .

[0076] When the motor 90 rotates clockwise, the meshing movement of the gear 92 and the rack 94 causes the movable bracket 26 to move horizontally in a direction away from the fixed shell 14. The third support plate 4 is sleeved in the second track 22 on the movable bracket 26 and moves in two directions, horizontally and upward. Since the fixed bracket 16 is stationary, the first track 12 on the fixed bracket 16 limits the horizontal movement of the third support plate 4. Therefore, the third support plate 4 can only move upward in the first direction. In conjunction with the second track 22, the third support plate 4 can move upward to achieve a lifting effect.

[0077] The third support plate 4 moves up and down, and the principle is as follows:

[0078] In the initial state, the third support plate 4 is below the second support plate 20, and the third support plate 4 is simultaneously sleeved within the first track 12 and the second track 22. When the deployment command is issued, the motor 90 rotates forward and drives the movable bracket 26 to move outward through the meshing movement of the gear 92. Under the dual action of the first track 12 and the second track 22, the third support plate 4 is rising synchronously to support the flexible screen 3 during the process of slowly deploying the flexible screen 3.

[0079] When the movable bracket 26 reaches the maximum stroke position, the third support plate 4 has risen to be flush with the second support plate 20 , playing the role of supporting the flexible screen 3 .

[0080] The motor 90 is reversed, and the screen can be reduced in size in the same manner as the unfolding principle.

[0081] The electronic device proposed in the present application can make the flexible screen 3 retractable and can solve the problem of insufficient support of the flexible screen 3 and sinking when pressed.

[0082] It should be noted that the electronic device may be a smart phone, a tablet computer, an e-reader, a wearable device, etc., which are not listed here one by one.
