DETAILED DESCRIPTION

[0048] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0049] The following is an explanation of some concepts and / or terms involved in the solutions provided in the embodiments of the present application.

[0050] Piezoelectric ceramics: electronic ceramic materials with piezoelectric properties. The main component of the crystal phase is ferroelectric grains. Since ceramics are polycrystalline aggregates with randomly oriented grains, the spontaneous polarization vectors of each ferroelectric grain are also chaotically oriented. In order for the ceramics to exhibit macroscopic piezoelectric properties, it is necessary to place the piezoelectric ceramics under a strong DC electric field for polarization treatment after they are fired and the end faces are electroded, so that the originally chaotically oriented polarization vectors are preferentially oriented along the direction of the electric field. After the polarization treatment, the piezoelectric ceramics will retain a certain macroscopic residual polarization strength after the electric field is removed, so that the ceramics have certain piezoelectric properties.

[0051] refer to Figure 1 , Figure 1 This is the diagram of the electric domain change due to the inverse piezoelectric effect. Figure 1 The middle figure (a) shows the distribution of electric domains before polarization treatment. Electric domains refer to areas with consistent polarization directions. It can be seen that the polarization directions of adjacent areas in Figure (a) are different. Figure 1 The middle figure (b) is a picture of the polarization treatment. A sufficiently high DC electric field is applied to the piezoelectric ceramic and maintained at a certain temperature and time. Under the action of the electric field, the piezoelectric ceramic stretches and the electric domain turns, that is, spontaneous polarization is oriented in a directional arrangement. The arrangement is oriented in the direction of the electric field. Figure 1 The middle figure (c) is the figure after polarization treatment, which shows the remaining polarization intensity after polarization treatment. Figure 2 , Figure 2 This is the principle diagram of the inverse piezoelectric effect. Under the action of the electric field, the polarization direction is arranged along the direction of the electric field.

[0052] refer to Figure 3 , Figure 3 This is the principle diagram of the positive piezoelectric effect. The positive piezoelectric effect refers to the phenomenon of electric polarization due to deformation. When physical pressure is applied to a piezoelectric material, the electric dipole moment in the material will shorten due to compression. At this time, the piezoelectric material will generate equal amounts of positive and negative charges on the opposite surfaces of the material to resist this change in order to maintain the original state, that is, an electric field is generated due to stress.

[0053] Reference Figure 4 , Figure 5 As shown, an embodiment of the present invention discloses an electronic device, including a device body 10, a first screen 11, a second screen 12 and a piezoelectric component 13 respectively arranged on the device body 10; the second screen 12 and the first screen 11 are respectively located on different surfaces of the device body 10; the device body 10 includes a first shell 18 and a second shell 19 that can rotate relative to each other, the first screen 11 is arranged on one side of the first shell 18, the second screen 12 is arranged on the other side of the first shell 18, and the first shell 18 is provided with a piezoelectric component 13; when the first shell 18 and the second shell 19 are folded, the piezoelectric component 13 located between the first shell 18 and the second shell 19 is pressed to wake up the second screen.

[0054] Specifically, refer to Figure 6 The first screen 11 is a foldable screen of an electronic device. When the first screen 11 is folded, the first housing 18 where the first split screen 111 is located contacts the second housing 19 where the second split screen 112 is located, generating mutual forces. The piezoelectric component 13 disposed under the first housing 18 and the second housing 19 is deformed under the pressure generated by the contact. The deformation causes an electric polarization phenomenon to occur inside the piezoelectric component 13, and charges with opposite signs are generated on the surface of the piezoelectric component 13, generating a voltage difference. The electrical signal obtained according to the voltage can be used as an electrical signal for waking up the second screen. When the force on the surface of the piezoelectric component 13 disappears, the piezoelectric component returns to a non-charged state. The amount of charge generated on the surface of the piezoelectric component 13 is proportional to the pressure received. Therefore, if the piezoelectric component generates a charge, it indicates that the first housing 18 and the second housing 19 are in a folded state, and the second screen can be awakened according to the generated electrical signal. If the piezoelectric component does not generate an electrical signal, it indicates that the first housing 18 and the second housing 19 are in an unfolded state at this time, and there is no need to wake up the second screen.

[0055] Furthermore, the piezoelectric component includes: positive / negative (+ / -) terminals, the P+ terminal of the piezoelectric component 13 is connected to the corresponding circuit of the PCB (Printed Circuit Board) through a capacitor, the PCB is a device that provides mechanical support for fixing and assembling various electronic components such as integrated circuits, and realizes wiring and electrical connection or electrical insulation between various electronic components such as integrated circuits, the P- terminal is connected to the mainboard GND (Ground), the positive input of the peripheral circuit is connected to the P+ terminal, and the tail end of the circuit is connected to the P- terminal to form a loop, the peripheral circuit is a control circuit that connects the central processing unit with the peripheral device to realize data transmission, and is arranged on the PCB. After the piezoelectric component is subjected to pressure to generate current, it is input into the central processing unit after filtering and other related processing. The central processing unit responds accordingly according to the input electrical signal, turns on the power switch of the second screen, and wakes up the second screen. Reference Figure 7 After the electronic device is folded, the piezoelectric component arranged under the housing of the electronic device generates current under the action of mechanical stress, and the positive piezoelectric film generates current. The positive and negative ends of the electric field are connected to the load circuit. The load circuit is a circuit that drives whether the second screen is awakened. Under the action of the current, the second screen is awakened.

[0056] In addition, the first screen 11 and the second screen 12 are flexible display screens. The first screen 11 may include two split screens or three split screens. Figure 4 The vertical folding shown can also be horizontal folding. The present invention does not limit the style and number of folding screens. For different types of folding screens, the method of waking up the second screen is the same as above. Figure 8 , Figure 8It is a schematic diagram of another type of folding screen. The first screen 11 is folded left and right. After folding, the first split screen 111 and the second split screen 112 are tightly fitted together. The second screen 12 is located on the other side opposite to the first split screen. The piezoelectric component 13 can be arranged under the first shell 18 where the first split screen 111 is located, and under the second shell 19 where the second split screen 112 is located. After the first shell 18 and the second shell 19 are folded, the piezoelectric component is subjected to pressure, generates current, and then wakes up the second screen 12.

[0057] A piezoelectric component can be set under the first shell 18 or the second shell 19 of the first screen, or multiple piezoelectric components can be set. The location of the piezoelectric component can be set according to actual needs, and the embodiment of the present invention does not limit this. The use of a piezoelectric component can generate an electrical signal in a state of very small deformation. Therefore, the use of a piezoelectric component can control whether the second screen is awakened only according to the change of external force. The production cost is low, the implementation method is simple, and it is suitable for popularization and use.

[0058] Optionally, refer to Figure 4 The electronic device also includes a first magnetic component 14 and a second magnetic component 17. The first magnetic component 14 is arranged on the first shell 18, and the second magnetic component 17 is arranged on the second shell 19. The orthographic projection of the first magnetic component 14 on the plane where the first shell 18 is located overlaps with the orthographic projection of the piezoelectric component 13 on the plane where the first shell 18 is located. When the first shell 18 and the second shell 19 are folded, the first magnetic component 14 and the second magnetic component 17 are attracted to each other.

[0059] Specifically, the first magnetic member 14 and the second magnetic member 17 can be arranged at the frame of the first shell 18 and the second shell 19. The first magnetic member 14 and the second magnetic member 17 are symmetrically arranged. After the first shell 18 and the second shell 19 are folded, the first shell 18 and the second shell 19 are closely fitted to prevent accidental folding and opening when carried. In addition, under the action of the first magnetic member 14 and the second magnetic member 17, the fit between the first shell 18 and the second shell 19 becomes tighter, so that the piezoelectric component 13 is subjected to greater pressure, and the piezoelectric component can work more reliably, preventing the second screen from being effectively awakened when the first shell 18 and the second shell 19 are folded due to insufficient pressure on the piezoelectric component. In addition, the orthographic projection of the first magnetic member 14 on the plane where the first shell 18 is located overlaps with the orthographic projection of the piezoelectric component 13 on the plane where the first shell 18 is located, so that compared with the method of using the Hall sensor and the magnet, the use of the piezoelectric component and the magnetic member can allow the magnetic member to exert the maximum auxiliary force. The number of magnetic members can be two mutually symmetrical arrangements, or 4, 6 symmetrical arrangements, etc. The embodiments of the present invention are not limited here.

[0060] Optionally, refer to Figure 4 When the first shell 18 and the second shell 19 are folded, the piezoelectric component 13 is located between the first magnetic component 14 and the second magnetic component 17 .

[0061] Specifically, the piezoelectric component 13 and the first magnetic component 14 can be arranged to overlap each other in the space of the first shell 18 of the electronic device. The arrangement can be that the first magnetic component 14 is located on the surface of the piezoelectric component 13, or the first magnetic component 14 is located on the back of the piezoelectric component 13. Since the first magnetic component 14 and the second magnetic component 17 are symmetrically arranged, the closer the first magnetic component 14 or the second magnetic component 17 is to the piezoelectric component 13, the greater the magnitude of the force applied to the piezoelectric component and the greater the current generated, which makes it more reliable to wake up the second screen through the piezoelectric component. In addition, the first magnetic component 14 or the second magnetic component 17 and the piezoelectric component 13 can also be arranged side by side, or specifically arranged according to the spatial structure of the specific electronic device, which is not limited in the embodiments of the present invention.

[0062] Optionally, refer to Figure 4 , including a plurality of first magnetic members 14 and a plurality of second magnetic members 17 , the first magnetic members 14 are arranged at intervals along the circumferential edge of the first shell 18 , and the second magnetic members 17 are correspondingly arranged along the circumferential edge of the second shell 17 .

[0063] Specifically, a plurality of first magnetic members 14 and a plurality of second magnetic members 17 can be respectively provided, and a plurality of first magnetic members 14 are arranged at intervals along the circumferential edge of the first shell 18, and the second magnetic members 17 are arranged symmetrically with respect to the positions of the first magnetic members 14, so as to increase the mutual attraction force between the first shell 18 and the second shell 19 when they are folded, and increase the pressure received by the piezoelectric component, so as to more reliably wake up the second screen.

[0064] Optionally, refer to Figure 4 The first shell 18 is provided with a camera assembly 15, and the distance between the first magnetic member 14 and the camera assembly 15 is greater than or equal to 5 mm.

[0065] Specifically, the sensors of the camera assembly 15 respond to magnetic fields. If magnetic components are placed next to these sensors, the magnetic field will interfere with or temporarily disable the sensors. Not only will the accuracy of the sensors be reduced, but the movable range of the lens will also be limited. Therefore, the first magnetic component 14 can be set at a position greater than or equal to 5 mm from the camera assembly 15 of the electronic device to avoid the magnetic field interfering with the operation of the camera assembly 15. In the entire electronic device, the number of magnetic components should be less than a preset threshold, such as 7, to reduce interference with the camera assembly.

[0066] Optionally, refer to Figure 4The piezoelectric component 13 includes a first piezoelectric component and a second piezoelectric component. The first piezoelectric component is disposed in the first shell 18, and the second piezoelectric component is disposed in the second shell 19. When the first shell 18 and the second shell 19 are folded, the first piezoelectric component and the second piezoelectric component are opposite to each other.

[0067] Specifically, the piezoelectric component 13 arranged in the first shell 18 serves as the first piezoelectric component, and the piezoelectric component 13 arranged in the second shell serves as the second piezoelectric component. The positions of the first piezoelectric component and the second piezoelectric component are symmetrical to each other. Since the first magnetic component 14 overlaps with the first piezoelectric component, and the second magnetic component 17 overlaps with the second piezoelectric component, when the first shell 18 and the second shell 19 are folded, the piezoelectric components 13 respectively located in the first shell 18 and the second shell 19 generate current under the action of mutual pressure to wake up the second screen 12. Setting two groups of symmetrical piezoelectric components 13 can avoid the situation where the second screen cannot be woken up when only a single piezoelectric component fails. At the same time, it can avoid the situation where the piezoelectric components at different positions are subjected to different forces when the first shell 18 and the second shell 19 are folded, so that the piezoelectric components at some positions may not be able to effectively wake up the second screen. By symmetrically setting four piezoelectric components, the operation of the piezoelectric components can be made more reliable.

[0068] Optionally, refer to Figure 4 The electronic device includes a rotating shaft 16, a first side of a first shell 18 is connected to the rotating shaft 16, a second side of the first shell 18 is provided with at least one piezoelectric component, and the first side is opposite to the second side.

[0069] Specifically, the rotating shaft is a component that allows the first shell 18 to rotate relative to the second shell 19. The side connected to the first shell 18 is the first side, and the side opposite to the first side is the second side. A piezoelectric component 13 can be set at the second side to enable the first shell and the second shell to be attracted.

[0070] The shaft 16 can be made of zirconium alloy liquid metal or other materials to increase the service life of the shaft and reduce the creases generated when the first screen is folded. Furthermore, the piezoelectric component includes a piezoelectric material film to reduce the internal space occupied by the electronic device. The piezoelectric material film can be a piezoelectric ceramic, which has strong piezoelectricity, high dielectric constant, and can be processed into any shape, or other materials with piezoelectric effect, which are not limited in the embodiments of the present invention.

[0071] Optionally, refer to Figure 4 The piezoelectric component 13 is disposed under the frame of the first shell 18 and away from the bending position.

[0072] Specifically, when setting the position of the piezoelectric component 13, it can be set at a position away from the bend of the first shell 18. If the piezoelectric component 13 is set at the bend, when the first shell 18 is folded, the mechanical bending angle generated at the bend is large, which can easily cause damage to the piezoelectric component itself. Therefore, setting it at a position away from the bend of the first shell 18 can both realize the awakening of the second screen and avoid the piezoelectric component from being damaged and affecting the performance.

[0073] In addition, a piezoelectric component may be provided at any position of the screen or frame to realize double-clicking the screen or other operations by applying pressure to the piezoelectric component to open the camera or start other services, which is not limited in the embodiments of the present invention.

[0074] Optionally, refer to Fig.10 The piezoelectric component includes a piezoelectric material and a control circuit electrically connected to the piezoelectric material; the control circuit includes a first trigger circuit 20, a second trigger circuit 30 and a third trigger circuit 40 connected in sequence; the first trigger circuit 20 is used to receive an electrical signal generated by the deformation of the piezoelectric material, and output a first high-level signal to the second trigger circuit 30 based on the electrical signal to turn on the second trigger circuit 30, so that the second trigger circuit 30 outputs a second high-level signal to the third trigger circuit 40 to turn on the third trigger circuit 40, and the third trigger circuit 40 is used to wake up the second screen when turned on.

[0075] Optionally, the first trigger circuit 20 includes: a first switch 23, a first power supply unit 22, a voltage stabilizing unit 21, a first resistor 25, a second resistor 26, a third resistor 27, and a first ground terminal 24; one end of the voltage stabilizing unit 21 is connected to the piezoelectric material, the other end of the voltage stabilizing unit 21 is connected to one end of the first resistor 25, the other end of the first resistor 25 is connected to a first connection point of the first switch 23, the second connection point of the first switch 23 is connected to one end of the second resistor 26, the other end of the second resistor 26 is connected to the first power supply unit 22, the third connection point of the first switch 23 is connected to one end of the third resistor 27, and the other end of the third resistor 27 is connected to the first ground terminal 24; the electrical signal generated by the deformation of the piezoelectric material is stabilized by the voltage stabilizing unit 21, triggering the first switch 23 to open, so that the first power supply unit 22 sends a first high level signal to the second trigger circuit 30.

[0076] Specifically, in the embodiment of the present invention, after receiving the electrical signal, the voltage can be stabilized by the filter circuit to filter out the clutter of the interference circuit to protect the electronic equipment. The filtering method can use passive components such as capacitors or inductors to achieve the purpose of filtering by utilizing their energy storage characteristics for voltage and current. Fig.10When the electronic device is folded, a level E is generated from the piezoelectric module P+, ​​and after being stabilized by the voltage stabilizing unit 21, the first switch 23 (TR1) is triggered to open. The first switch 23 only needs a very small current to open, and the first power supply unit 22 (VCC1.8 (Volt Current Condenser, power supply voltage)) generates a first high level signal to input into the second trigger circuit 30.
