[0026] It will be understood by those skilled in the art that, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as those generally understood by those skilled in the art in the art to which the present invention belongs. It should also be understood that terms such as those defined in common dictionaries should be understood to have meanings consistent with the meanings in the context of the prior art, and will not be interpreted with idealized or overly formal meanings unless defined as herein.

[0027] To describe the screen protection method and system in detail, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Figure 1 The schematic flow of the screen protection method according to the embodiment of the present invention is shown.

[0029] like Figure 1 As shown, the screen protection method of the embodiment of the present invention is used in a target product with a folding function, the target product includes a first folding portion and a second folding portion, at least one of the first folding portion and the second folding portion is a screen, and the screen protection method includes:

[0030] S100: Detect whether there is a folding action between the first folding portion and the second folding portion, and when there is a folding action between the first folding portion and the second folding portion, start a detection component.

[0031] Among them, the detection component may include a camera module located on the first folding part and / or the second folding part; the folding part in the opposite direction is AI scanned by the camera module, and it is determined whether there is a target object located outside a preset range on the folding part in the opposite direction, and the folding part in the opposite direction may be the first folding part and / or the second folding part.

[0032] Specifically, detecting whether there is a folding action between the first folding portion and the second folding portion of the target product includes three methods. First, detecting the current angle between the folding parts of the first folding portion and the second folding portion. When the angle is less than a first preset value, it is determined that there is a folding action between the first folding portion and the second folding portion. Since the angle between the first folding portion and the second folding portion is usually greater than 90° during normal use of the product by the user, the first preset value can be set to 90°. When the angle between the first folding portion and the second folding portion of the product is less than 90°, it does not conform to the angle range for the user to normally view the screen. At this time, it can be predicted that there is a folding action between the first folding portion and the second folding portion of the target product. In addition, the first preset value can also be set by the user according to the user's habit of using the product.

[0033] Second: Detect the angle at which the first folding part flips toward the side close to the second folding part. When the angle is greater than the second preset value, it is determined that there is a folding action between the first folding part and the second folding part. In this detection method, the angle at which the first folding part flips based on the static state is detected. When the flipping angle is small, it indicates that the user is adjusting the angle according to viewing needs. When the flipping angle is large, it can be predicted that there is a folding action between the first folding part and the operation. The specific second preset value can be flexibly set according to product differences and user usage habits. Similarly, the angle at which the second folding part flips toward the side close to the first folding part can also be detected. When the angle is greater than the second preset value, it is determined that there is a folding action between the first folding part and the second folding part. Specifically, the flipping angle of the flipping side can be detected based on the static side of the first folding part or the second folding part.

[0034] Third: the process of detecting whether there is a folding action between the first folding part and the second folding part of the target product may also include: detecting the current distance information between the first folding part and the second folding part by means of distance sensors arranged on the first folding part and the second folding part; when the detected distance is less than a third preset value, it is determined that there is a folding action between the first folding part and the second folding part; similarly, the third preset value may also be flexibly set according to the specific product and user usage habits.

[0035] S200: Determine, by means of a detection component, whether there is a target object outside a preset range on the first folding portion and / or the second folding portion in the opposite direction of the folding surface.

[0036] Among them, when the detection component includes a camera module, the camera module can use the camera of the target product. When it is predicted that there is a folding action between the first folding part and the second folding part, the camera module of the target product can be started, and the second folding part below the first folding part can be AI scanned or the first folding part below the second folding part can be scanned through the camera module. Specifically, based on the side where the camera module is provided, the folding part on the corresponding side can be scanned, and it can be determined whether there is a target object located outside the preset range on the folding part in the opposite direction of the folding (which can be the first folding part, the second folding part or the first folding part and the second folding part), so as to determine whether early warning or intervention is possible according to the judgment result.

[0037] Specifically, the process of determining the above-mentioned preset range may further include: after the target product is started, obtaining the startup and scanning authority of the camera module; then, scanning the folding part in the opposite direction in the initial state (without any foreign matter) through the camera module, and generating a parameter reference value, and determining the preset range according to the parameter reference value. In actual application, if an object outside the preset range appears, it can be confirmed that there is a target object on the folding part, and corresponding measures can be taken to prevent damage.

[0038] In a specific embodiment of the present invention, the detection component may also include a pressure sensor arranged on the first folding portion / the second folding portion, and further, a pressure sensor may be arranged at a specified position of the first folding portion or the second folding portion, for example, a weak area that is easily damaged by external compression or a core area that needs to be protected. When it is determined that there is a folding action between the first folding portion and the second folding portion, the pressure signal at the corresponding position is collected by the pressure sensor; wherein, when the pressure signal is greater than a preset reference value, it is determined that there is a target object on the second folding portion, and the folding action of the first folding portion is warned and intervened. Normally, the pressure sensor is arranged on a folding portion that is not often flipped (such as a keyboard), rather than on a folding portion that is not often flipped (for example, a screen).

[0039] Among them, after the target product is started, the folding part where the pressure sensor is located without any foreign matter can be calibrated and tested, and a corresponding reference value can be set. In the actual detection process, it can be determined whether there is a target object on the folding part based on the reference value. It can be seen that the pressure sensor can be set in multiple places, and the specific position can be adjusted according to product differences.

[0040] S300: When the target object exists on the folding portion in the opposite direction of the folding, a warning and intervention are given to the folding action.

[0041] Among them, warning and intervening in the folding action further includes: sending a sound warning signal through a speaker of the target product; and / or sending an optical warning signal through an indicator light of the target product, and then when the presence of the target object is detected, timely sound and light warnings are issued to prevent the user from continuing to operate and causing damage to the first folding part or the second folding part.

[0042] In another specific embodiment of the present invention, an electric spring assembly may be provided at the junction of the first folding portion and the second folding portion; warning and intervening the folding action includes: controlling the electric spring assembly by alternating current to prevent the folding action of the first folding portion.

[0043] Among them, Figure 3 As shown, the electric spring assembly includes a magnet 31, a coil, a spring 32, and metal paddles 33 at both ends of the spring. When the electronic product receives a signal that requires a warning and intervention in the folding action, a directional electric signal will be generated to the electric spring assembly 3. The electric signal passes through the magnetic field of the permanent magnet wound on the spring 32. According to Ampere's left-hand rule, the metal paddles 33 at the two terminals of the electric spring will generate a lasting resistance, thereby preventing the screen with the electric spring from being buckled. Therefore, when it is determined that the target object exists, the target product can be directly triggered to generate an alternating current, and the alternating current generates a variable magnetic field to control the permanent magnet to generate an alternating driving force. The alternating driving force is used to prevent the folding action or cancel the prevention of the folding action. While achieving an audible and visual warning, the electric spring assembly is directly controlled by an electric signal to prevent the folding action.

[0044] It should be noted that in the embodiment of the present invention, at least one of the first folding part and the second folding part is a screen, or both of them may be screens, such as a foldable screen mobile phone. For example, when the target product is a laptop computer, the first folding part and the second folding part may be a keyboard and a screen respectively. If the target product is a Pad, the first folding part and the second folding part may be a screen and a cover plate or a shell covering the screen respectively. The present application does not limit specific electronic products. For foldable electronic products, the method of the present invention can be used to perform foreign object warning before folding.

[0045] Specifically, Figure 2In the schematic structure of the electronic product shown, the electric spring assembly 3 is arranged at the junction between the screen 2 and the keyboard 5, and the pressure sensor 4 is arranged in the middle of the keyboard. During the application process, the keyboard 5 area is AI scanned by the camera 1, and / or based on the detection result of the pressure sensor 4, it is determined whether there are other foreign objects thereon, and when foreign objects are present, an early warning is given through the sound and light function of the product itself, and an alternating electrical signal is generated through the product system to the electric spring assembly 3, and the electric spring assembly 3 is used to prevent the screen 1 from snapping together, thereby preventing the screen 1 or keyboard 5 from being damaged by foreign objects.

[0046] Among them, for dual-screen electronic products, the pressure sensor can be set on any one of the screens or on both screens at the same time. The pressure sensor can use the sensor that comes with the electronic product, or on the basis of the built-in pressure sensor, an additional pressure sensor can be set at a sensitive position that needs to be protected. The present invention does not limit the specific position, number and source of the pressure sensor.

[0047] Corresponding to the above-mentioned screen protection method, the present invention also provides a screen protection system, including: a detection unit, used to detect whether there is a folding action between the first folding part and the second folding part, and when there is a folding action between the first folding part and the second folding part, starting a camera module located on the first folding part and / or the second folding part; a judgment unit, used to perform an AI scan on the folding part in the opposite direction of the folding through the camera module, and judge whether there is a target object located outside a preset range on the folding part in the opposite direction of the folding; an early warning unit, used to warn and intervene in the folding action when the target object exists on the folding part in the opposite direction of the folding.

[0048] It should be noted that the embodiments of the screen protection system provided by the present invention can refer to the description in the embodiments of the screen protection method, which will not be described in detail here.

[0049] The screen protection method and system according to the present invention detects whether there is foreign matter on the corresponding folding part through a camera or pressure sensor on an electronic product with a folding function. When it is determined that a foreign matter exists, an alarm reminder can be given through sound and light, and an alternating electric signal can be generated through the product system to the electric spring assembly. The electric spring assembly prevents the screen from snapping together. The method and system can be applied to various types of folding electronic products to effectively prevent accidental damage to the product screen.

[0050] The screen protection method and system according to the present invention are described above by way of example with reference to the accompanying drawings. However, it should be understood by those skilled in the art that various improvements can be made to the screen protection method and system proposed by the present invention without departing from the content of the present invention.
