[0003] Currently, electronic devices typically have under-screen pressure sensitivity, such as... Figure 1 As shown, when the touchscreen module (11) is pressed, it can trigger the button function corresponding to the upper pressure button module (14) or the lower pressure button module (15). The existing solution usually sets an opening (13) on the middle frame (12) and then arranges the pressure-sensitive module at the opening (13) of the middle frame. However, setting an opening (13) on the middle frame can easily affect the overall layout of the electronic device. Summary of the Invention

[0004] This application aims to provide a foldable screen electronic device that at least solves the problem of opening holes in the mid-frame affecting the overall layout of the electronic device.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] This application provides a foldable screen electronic device, including: a frame, a pressure-sensitive module, and a flexible screen; wherein,

[0007] The frame includes a first support plate and a second support plate arranged opposite to each other, and the flexible screen is disposed on the side of the first support plate away from the second support plate;

[0008] At least one of the first support plate and the second support plate is provided with a pressure-sensitive area;

[0009] The pressure-sensitive area includes multiple spaced and parallel support members, with a reinforcing member between two adjacent support members;

[0010] The pressure-sensitive module is disposed in the pressure-sensitive area.

[0028] The following is combined Figure 2 - Figure 8 This application describes the foldable screen electronic device described in the embodiments.

[0029] like Figure 2As shown, in some embodiments of this application, the foldable screen electronic device may specifically include: a frame 2, a pressure-sensitive module 3, and a flexible screen 4; wherein, the frame 2 may include a first support plate 21 and a second support plate disposed opposite to each other, and the flexible screen 4 may be disposed on the side of the first support plate 21 opposite to the second support plate; pressure-sensitive areas may be provided on the first support plate 21 and / or the second support plate; as shown Figure 4 As shown, the pressure-sensitive area may include multiple spaced and parallel support members 51, with a reinforcing member 52 between two adjacent support members 51; the pressure-sensitive area can be used to install the pressure-sensitive module 3.

[0030] In this embodiment, the pressure-sensitive area includes multiple spaced and parallel support members 51, with a reinforcing member 52 between adjacent support members 51. This allows the first support plate 21 or the second support plate to form a hollow structure in the pressure-sensitive area, where the pressure-sensitive module 3 is disposed, facilitating wiring arrangement. The hollow structure in the pressure-sensitive area avoids the need for openings in the frame 2, improving the overall layout of the foldable screen electronic device. Furthermore, the hollow structure in the pressure-sensitive area allows for heat conduction, effectively ensuring the heat dissipation of the frame 2.

[0031] The foldable screen electronic device described in this application embodiment is specifically an electronic device with folding function. The foldable screen electronic device can switch between a folded state and an unfolded state. In the folded state, the size of the foldable screen electronic device becomes smaller and easier to carry; in the unfolded state, the size of the foldable screen electronic device becomes larger, the display area can be increased, and the display effect can be improved.

[0032] Specifically, the foldable screen electronic device includes a frame 2 and a flexible screen 4; the frame 2 can be used to support and fix the internal components of the foldable screen electronic device. The flexible screen 4 can be an OLED (Organic Light-Emitting Diode) display or an LED (light emitting diode) display. During the switching between the unfolded state and the folded state of the foldable screen electronic device, the flexible screen 4 can unfold and fold accordingly.

[0033] Specifically, the frame 2 may include a first support plate 21 and a second support plate, which may be disposed on opposite sides of the frame 2; the first support plate 21 is disposed on one side of the frame 2 to support the flexible screen 4; the second support plate may be disposed on the other side of the frame 2.

[0034] Specifically, a pressure-sensitive area may be provided on the first support plate 21, or a pressure-sensitive area may be provided on the second support plate, or both the first support plate 21 and the second support plate may be provided with pressure-sensitive areas. The pressure-sensitive areas are provided in correspondence with the pressure-sensitive module 3. The pressure-sensitive areas can be used to set the pressure-sensitive module 3. The specific settings can be made according to actual needs. This application embodiment does not make specific limitations in this regard.

[0035] Specifically, the pressure-sensitive module 3 can convert pressure into an electrical signal. One set of pressure-sensitive modules 3 can work independently, or two sets of pressure-sensitive modules 3 can work together. The specific settings can be configured according to actual needs, and this application embodiment does not make specific limitations in this regard.

[0036] In one optional embodiment, the pressure-sensitive module 3 can be a component of a pressure button assembly. Since the pressure-sensitive module 3 is located in the pressure-sensitive area, when the user presses the screen, the pressure can be transmitted to the pressure-sensitive module 3, thereby triggering the corresponding button function.

[0037] Specifically, the pressure-sensitive area may include multiple spaced and parallel support members 51. The support member 51 may be a support rod or a support plate. The number of support members 51 may be three, ten, twenty, forty or seventy, etc., which can be set according to actual needs. This application embodiment does not make specific limitations in this regard.

[0038] Specifically, a reinforcing member 52 is provided between two adjacent support members 51. One end of the reinforcing member 52 is connected to one support member 51, and the other end of the reinforcing member 52 can be connected to another support member 51. The reinforcing member 52 can be a reinforcing rod or a reinforcing plate, etc., and can be set according to actual needs. This application embodiment does not make specific limitations in this regard.

[0039] Specifically, multiple parallel and spaced reinforcing members 52 can be provided between two adjacent support members 51. The reinforcing members 52 can be arranged in an array along the pressure-sensitive area.

[0040] Optionally, the frame 2 includes a first frame 23, a connecting portion 25, and a second frame 24; the first frame 23 is disposed on one side of the connecting portion 25, and the second frame 24 is disposed on the other side of the connecting portion 25; both the first frame 23 and the second frame 24 are rotatably connected to the connecting portion 25, so that the first frame 23 can be unfolded or folded relative to the second frame 24; a first support plate 21 is laid on one side of the first frame 23, the connecting portion 25, and the second frame 24, and a second support plate is laid on the other side of the first frame 23, the connecting portion 25, and the second frame 24; both the first support plate 21 and the second support plate are flexible metal structures.

[0041] In this embodiment, the first frame 23 is disposed on one side of the connecting portion 25, and the second frame 24 is disposed on the other side of the connecting portion 25. Both the first frame 23 and the second frame 24 are rotatably connected to the connecting portion 25, allowing the first frame 23 to be unfolded or folded relative to the second frame 24, thus enabling the foldable screen electronic device to switch between an unfolded state and a folded state. The first support plate 21 is laid on one side of the first frame 23, the connecting portion 25, and the second frame 24, and the second support plate is laid on the other side of the first frame 23, the connecting portion 25, and the second frame 24. Both the first support plate 21 and the second support plate are flexible metal structures, thus preventing interference between the first support plate 21 and the second support plate during the unfolding or folding of the first frame 23 relative to the second frame 24.

[0042] Specifically, both the first support plate 21 and the second support plate are flexible metal structures, which can not only provide certain support, but also generate adaptive deformation and buffer and disperse the pressure, avoiding stress concentration that could cause the pressure-sensitive module 3 to crack. In addition, it can also ensure the signal quantity of the pressure-sensitive module 3 and reduce the failure rate of the pressure-sensitive module 3 during production, transportation and assembly.

[0043] Specifically, the first support plate 21 can be a stainless steel sheet, an aluminum alloy sheet, etc., and the second support plate can be a stainless steel sheet, an aluminum alloy sheet, etc. The specific settings can be made according to actual needs, and this application embodiment does not make specific limitations in this regard.

[0044] Specifically, the pressure-sensitive area can be opposite to the first frame 23, or opposite to the second frame 24, or opposite to the connecting part 25, which can increase the arrangement space of the pressure-sensitive module 3. Furthermore, the pressure-sensitive areas are set in a one-to-one correspondence with the pressure-sensitive modules 3. By adjusting the setting position of the pressure-sensitive areas, for example, by setting the pressure-sensitive area entirely on the first support plate 21, or setting the pressure-sensitive area entirely on the second support plate, full-screen pressure sensitivity can be achieved, improving the user experience.

[0045] Specifically, the first frame 23 is disposed on one side of the connecting part 25 and can be connected to the connecting part 25 via a hinge to achieve a rotatable connection between the first frame 23 and the connecting part 25. The second frame 24 is disposed on the other side of the connecting part 25 and can be connected to the connecting part 25 via a hinge to achieve a rotatable connection between the second frame 24 and the connecting part 25.

[0046] Optionally, such as Figure 2 As shown, the pressure-sensitive area is positioned opposite to the connecting part 25.

[0047] In this embodiment, the pressure-sensitive area is arranged opposite to the connecting part 25, which can make reasonable use of the space of the foldable screen electronic device at the connecting part 25, save the overall layout space of the foldable screen electronic device, and help to make the foldable screen electronic device thinner and lighter.

[0048] Optionally, such as Figure 5 As shown, the pressure-sensitive module 3 includes a pressure-sensitive component and an insulating layer 33 wrapped around the pressure-sensitive component. The pressure-sensitive component includes a pressure-sensitive structure 31 and at least two conductors 32. The conductors 32 are laid on the support member 51 and the reinforcing member 52, and there is a gap between two adjacent conductors 32. The gap is set along the length direction of the support member 51. The pressure-sensitive structure 31 covers the gap and is connected to the two adjacent conductors 32 respectively.

[0049] In this embodiment, conductor 32 can be laid on support member 51 and reinforcing member 52 for easy fixing of conductor 32. Pressure-sensitive structure 31 is connected to two adjacent conductors 32 respectively, realizing series connection between pressure-sensitive structure 31 and conductor 32, so that conductor 32 can transmit signals of pressure-sensitive structure 31. Insulating layer 33 wraps around pressure-sensitive component to protect conductor 32 and pressure-sensitive structure 31, and can prevent short circuit of pressure-sensitive component.

[0050] Specifically, there is an insulating layer 33 between the conductor 32 and the support member 51, and there is an insulating layer 33 between the conductor 32 and the reinforcing member 52.

[0051] Specifically, there is a gap between two adjacent conductors 32, the gap is arranged along the length direction of the support member 51, the pressure-sensitive structure 31 covers the gap, and the two ends of the pressure-sensitive structure 31 are respectively connected to the two adjacent conductors 32, so that the pressure-sensitive structure 31 can be arranged on the support member 51.

[0052] Specifically, the pressure-sensitive structure 31 can be a structure made of piezoelectric material, which is a crystalline material that generates a voltage between its two ends when subjected to pressure, including inorganic piezoelectric materials and inorganic piezoelectric materials.

[0053] Specifically, conductor 32 can be a wire or a metal layer that can transmit signals. The specific configuration can be determined according to actual needs, and this application embodiment does not impose any specific limitations on it.

[0054] Specifically, a pressure-sensitive structure 31 can be formed by applying piezoelectric material to the support member 51 through processes such as printing or coating. Furthermore, before applying the piezoelectric material to the support member 51 through processes such as printing or coating, an insulating layer 33 needs to be applied to the support member 51.

[0055] In some optional embodiments of this application, combined with Figure 4 and Figure 6As shown, when the first frame 23 is unfolded relative to the second frame 24, the first frame 23, the connecting part 25 and the second frame 24 can be arranged sequentially along the first direction; the reinforcing member 52 is arranged along the first direction, and the supporting member 51 is arranged along the second direction, which is perpendicular to the first direction.

[0056] In this embodiment, when the first frame 23 is unfolded relative to the second frame 24, the first frame 23, the connecting part 25, and the second frame 24 can be arranged sequentially along the first direction, and the support member 51 is arranged along the second direction, which is perpendicular to the first direction. Since the pressure-sensitive structure 31 is arranged on the support member 51, the arrangement direction of the pressure-sensitive structure 31 is perpendicular to the folding direction of the foldable screen electronic device. During the folding process of the foldable screen electronic device, the pressure-sensitive structure 31 can be prevented from being deformed due to force.

[0057] In some alternative embodiments of this application, combined with Figure 4 and Figure 7 As shown, when the first frame 23 is unfolded relative to the second frame 24, the first frame 23, the connecting part 25 and the second frame 24 can be arranged sequentially along the first direction; the support member 51 is arranged along the first direction, and the reinforcing member 52 is arranged along the second direction, which is perpendicular to the first direction.

[0058] In this embodiment, when the first frame 23 is unfolded relative to the second frame 24, the first frame 23, the connecting part 25, and the second frame 24 can be arranged sequentially along the first direction, and the support member 51 is arranged along the first direction. Since the pressure-sensitive structure 31 is arranged on the support member 51, the setting direction of the pressure-sensitive structure 31 is the same as the folding direction of the foldable screen electronic device. During the folding process of the foldable screen electronic device, the first support plate 21 and the second support plate fold, which can trigger the pressure-sensitive structure 31, making it convenient to detect the unfolded and folded state of the foldable screen electronic device.

[0059] Specifically, the pressure-sensitive module 3 can be a component of the detection unit. In this way, during the unfolding or folding process of the foldable screen, the first support plate 21 and the second support plate can unfold or bend together, thereby triggering the pressure-sensitive module 3, so that the detection unit can detect the unfolding and folding state of the foldable screen electronic device.

[0060] Optionally, the pressure-sensitive module 3 is disposed between the flexible screen 4 and the first support plate 21.

[0061] In this embodiment, the pressure-sensitive module 3 is disposed between the flexible screen 4 and the first support plate 21, so that the pressure-sensitive module 3 can be disposed below the flexible screen 4, which can improve the sensitivity of the pressure-sensitive module 3.

[0062] Specifically, such as Figure 2As shown, the first support plate 21 can be used to support the flexible screen 4.

[0063] Optionally, the electronic device further includes a circuit board 6 and a signal line layer 7; the signal line layer 7 and the pressure-sensitive module 3 are disposed on the same side of the first support plate 21 or the second support plate; the signal line layer 7 is electrically connected to the pressure-sensitive module 3 and the circuit board 6 respectively, and is used to transmit the signal of the pressure-sensitive module 3 to the circuit board 6.

[0064] In this embodiment, the signal line layer 7 and the pressure-sensitive module 3 are disposed on the same side of the first support plate 21 or the second support plate, and the signal line layer 7 is electrically connected to the pressure-sensitive module 3 and the circuit board 6 respectively, so that the signal line layer 7 can transmit the signal of the pressure-sensitive module 3 to the circuit board 6.

[0065] Specifically, the signal line layer 7 can be integrated on the surface of the first support plate 21 or the second support plate for transmitting signals.

[0066] Specifically, circuit board 6 can be a printed circuit board (PCB) or a flexible printed circuit (FPC), etc., and can be set according to actual needs. This application embodiment does not make specific limitations in this regard.

[0067] like Figure 2 As shown, circuit board 6 can be an FPC board, and the foldable screen electronic device can also include a main board 81 and a sub-board 82; the main board 81 can be used to carry electronic components and transmit signals; the sub-board 82 can be used to carry electronic components and transmit signals.

[0068] Furthermore, the FPC board is electrically connected to the motherboard 81, which can transmit signals to the motherboard 81; the FPC board is electrically connected to the sub-board 82, which can transmit signals to the sub-board 82.

[0069] Optionally, the signal line layer 7 is connected to the circuit board 6 by conductive adhesive, or the signal line layer 7 is connected to the circuit board 6 by thermoforming.

[0070] In this embodiment, the signal line layer 7 can be connected to the circuit board 6 by conductive adhesive, or the signal line layer 7 can be connected to the circuit board 6 by thermoforming. This can ensure the fixation of the signal line layer 7 to the circuit board 6 and also realize the electrical connection between the signal line layer 7 and the circuit board 6, thereby facilitating the transmission of the signal from the pressure-sensitive module 3 to the circuit board 6 by the new signal line layer.

[0071] Specifically, such as Figure 3 As shown, the connecting layer 9 can be a conductive adhesive layer or a thermosetting solder layer.

[0072] Specifically, the signal line layer 7 can be disposed on the first support plate 21 or the second support plate, so that the first support plate 21 and the second support plate can be used to support the signal line layer 7. For example... Figure 3 As shown, the signal line layer 7 may be provided with through holes 72 to facilitate the connection of wires between different layers, the wires being used to transmit signals.

[0073] Optionally, the pressure-sensitive module 3 includes two sets, which are symmetrically arranged on opposite sides of the first support plate 21, or the two sets of pressure-sensitive modules 3 are symmetrically arranged on opposite sides of the second support plate.

[0074] In this embodiment, two sets of pressure-sensitive modules 3 are symmetrically arranged on opposite sides of the first support plate 21, or two sets of pressure-sensitive modules 3 are symmetrically arranged on opposite sides of the second support plate, which can improve the accuracy of the triggering of the pressure-sensitive modules 3.

[0075] like Figure 8 As shown, the working principle of the two pressure-sensitive modules 3 is as follows: The base is either the first support plate 21 or the second support plate. When an external force F is applied, the pressure-sensitive structure 31 in the pressure-sensitive module 3 undergoes slight deformation. Due to the difference in bending radii between the pressure-sensitive structures 31 on both sides of the base, the inner pressure-sensitive structures R1 and R2 are in a compressed state, while the outer pressure-sensitive structures R3 and R4 are in a stretched state. The resistance changes on both sides of the base are inconsistent. Since the deformation and resistance of the pressure-sensitive structure 31 are linearly related, the pressure is determined by detecting the pressure difference at both ends according to the Wheatstone bridge principle, and then converted into an electrical signal to achieve the corresponding function.

[0076] The foldable screen electronic device described in this application embodiment has at least the following advantages:

[0077] In this embodiment, the pressure-sensitive area includes multiple spaced and parallel support members, with a reinforcing member between adjacent support members. This allows the first or second support plate to form a hollow structure within the pressure-sensitive area. The pressure-sensitive module is disposed within the pressure-sensitive area, facilitating wiring arrangement for the module. The hollow structure formed by the first or second support plate in the pressure-sensitive area avoids the need for openings in the frame, improving the overall layout of the foldable screen electronic device.
