[0024] In another possible implementation manner of the first aspect, when the detection data includes a detection image, the control instruction includes a first instruction and a third instruction.

[0025] The control device is used to send a first instruction to the motion device; the motion device is used to respond to the first instruction and rotate at a first speed to drive the opening and closing device to move and perform a folding or unfolding operation of the device under test.

[0026] A control device is used to send a third instruction to the visual processing device; the visual processing device is used to collect a detection image corresponding to at least one folding angle of the device under test during a folding or unfolding operation in response to the third instruction at a second frequency.

[0027] In the present application, the visual processing device in the detection system obtains the detection image of the folding device during the folding / unfolding process, which is used to detect the synchronization of the folding device; the audio detection data of the folding device during the folding / unfolding process is obtained by the audio processing device of the detection system, which is used to detect abnormal noises of the folding device.

In addition, it can also provide effective data support for data analysis of equipment reliability.

[0028] In another possible implementation manner of the first aspect, when the detection data includes a torque detection value, the control instruction includes a first instruction and a fourth instruction.

[0029] The control device is used to send a first instruction to the motion device. The motion device is used to respond to the first instruction and rotate at a first speed to drive the opening and closing device to move and perform a folding or unfolding operation of the device under test;

[0030] The control device is used to send a fourth instruction to the torque sensor. The torque sensor is used to collect torque detection values ​​corresponding to each folding angle of the device under test during the folding or unfolding operation at a third frequency in response to the fourth instruction.

[0031] In the present application, the audio detection data of the folding device during the folding / unfolding process is obtained through the audio processing device of the detection system, which is used to detect abnormal noises of the folding device; the torque detection data of the folding device during the folding / unfolding process is obtained through the opening and closing device of the detection system, which is used to detect the opening and closing force and the virtual position of the folding device. An integrated detection system based on the integration of multiple acquisition devices automatically collects detection data of multiple types of reliability parameters, and the detection data is relatively accurate and reliable; and the detection system can be applied to the equipment detection of multiple reliability parameters of a large number of folding devices, which greatly improves the efficiency of equipment reliability detection. In addition, it can also provide effective data support for data analysis of equipment reliability.

[0032] In another possible implementation of the first aspect, the opening and closing device includes a fixed center, a first fixed plate, a second movable plate, a rotating disk, and a torque sensor. The first fixed plate is connected to the fixed center, the second movable plate is connected to the rotating disk, and the first fixed plate and the movable plate are connected by a hinge. The torque sensor is connected to the first fixed plate and the second movable plate.

[0033] The device under test includes a first folding part and a second folding part connected by a rotating shaft. When the device under test is placed in the opening and closing device, the first folding part is fixed to the first fixed plate and fits with the first fixed plate, and the second folding part is fixed to the second movable plate and fits with the second movable plate.

[0034] The torque sensor is used to collect torque detection values ​​corresponding to each folding angle of the device under test during the folding or unfolding operation at a third frequency in response to the fourth instruction.

[0035] In the present application, the torque detection data of the folding device during the folding / unfolding process is obtained through the opening and closing device of the detection system, which is used to perform the opening and closing force detection and virtual position detection of the folding device, and automatically collect the detection data of various types of reliability parameters, which are relatively accurate and reliable. In addition, keeping one fixed plate stationary and the other moving plate moving to realize the folding and unfolding of the folding device can minimize the data deviation caused by the simultaneous movement of the folding parts of the folding device, making the detection data more accurate.

[0036] In another possible implementation of the first aspect,

[0037] A control device is used to obtain the torque detection value corresponding to each folding angle, obtain a first corresponding relationship between the folding angle and the torque detection value, and obtain the opening and closing force detection result and the virtual position detection result of the device under test based on the first corresponding relationship; the folding angle is the angle between the first folding part and the second folding part.

[0038] Among them, in the first corresponding relationship, the larger the torque detection value is, the larger the opening and closing force of the device under test is, and the magnitude of the opening and closing force represents the magnitude of the force required to open or fold the device under test.

[0039] The greater the slope of the climbing curve of the torque detection value in the curve corresponding to the first corresponding relationship, the lower the virtual position degree of the device under test, and the lower the virtual position degree indicates that the smoother the opening or folding of the device under test is.

[0040] In this application, the virtual position feel of the folding device is related to the virtual position gap of the folding device itself and the elastic deformation of the folding part. Therefore, the virtual position problem generated by the folding device during the unfolding / folding process can be analyzed based on the torque detection value. Based on the torque detection value, it can be determined that the greater the slope of the climbing curve of the torque detection value, the shorter the opening and closing force climbing state, and the lower the virtual position detection result of the folding device. This method is simple, effective and relatively accurate.

[0041] In another possible implementation manner of the first aspect, the audio processing device is disposed at a first position of a connecting hinge between the first fixed plate and the second movable plate.

[0042] The audio processing device includes an audio collection unit.

[0043] The audio collection unit is used to collect audio detection values ​​corresponding to each folding angle of the device under test during the folding or unfolding operation at a first frequency in response to the second instruction.

[0044] In this application, the audio detection data of the folding device during the folding / unfolding process is obtained through the audio processing device in the detection system, which is used to detect abnormal sounds of the folding device and automatically collect audio detection data. The detection data is relatively accurate and reliable, and can provide effective data support for abnormal sound analysis of the device. In addition, the audio processing device is set near the hinge, and the collected audio detection value is closer to the actual state of the hinge, making the audio detection value more accurate.

[0045] In another possible implementation of the first aspect, the control device is used to obtain the audio detection value corresponding to each folding angle, obtain a second corresponding relationship between the folding angle and the audio detection value, and obtain the abnormal sound detection result of the device under test based on the second corresponding relationship.

[0046] Among them, the folding angle corresponding to the audio detection value being greater than the preset decibel threshold in the second corresponding relationship is the angle at which abnormal sound is generated when the device under test is folded / unfolded; the folding angle is the angle between the first folding part and the second folding part.

[0047] In the present application, the audio detection value greater than the preset decibel threshold is an abnormal sound. Based on the audio detection value, the angle at which the abnormal sound occurs during the folding / unfolding process of the folding device can be determined, thereby realizing the abnormal sound detection of the folding device.

[0048] In another possible implementation of the first aspect, the visual processing device includes an image acquisition unit.

[0049] The image acquisition unit is used to respond to the third instruction and acquire a detection image corresponding to at least one folding angle of the device under test during the folding or unfolding operation at a second frequency; the detection image includes images of the first folding part and the second folding part of the device under test.

[0050] In the present application, the visual processing device in the detection system obtains the detection image of the folding device during the folding / unfolding process, which is used to perform synchronization detection of the folding device, and automatically collects detection data of various types of reliability parameters, which are relatively accurate and reliable. In addition, it can also provide effective data support for data analysis of equipment reliability. The synchronization detection of the folding part of the folding device is performed through target recognition of the detection image, and the image data is more accurate.

[0051] In another possible implementation manner of the first aspect, the control device is used to obtain a detection image corresponding to at least one folding angle.

[0052] A control device is used to perform target recognition on a detection image and obtain a first edge, a second edge and a third edge in the detection image; the first edge is an edge corresponding to the first folded part image of the device under test in the detection image, the second edge is an edge corresponding to the second folded part image of the device under test in the detection image, and the third edge is an edge corresponding to the shaft image of the device under test in the detection image.

[0053] The control device is used to obtain a first angle between the first edge and the third edge, and a second angle between the second edge and the third edge, and obtain a synchronization detection result based on an angle deviation between the first angle and the second angle.

[0054] The smaller the angle deviation is, the higher the degree of synchronization between the first folding part and the second folding part of the device under test is, and the larger the angle deviation is, the lower the degree of synchronization between the first folding part and the second folding part of the device under test is.

[0055] In the present application, by detecting target recognition of the image, the first angle between the first folding part of the device under test and the rotating shaft, and the second angle between the second folding part and the rotating shaft are obtained, and the synchronization of the folding part of the device under test is detected based on the angular deviation between the first angle and the second angle, so that the image data is more accurate.

[0056] In another possible implementation manner of the first aspect, the motion device includes a motor and a motor drive; the motor is connected to the second movable plate.

[0057] The motor drive is used to control the motor to rotate at a first speed in response to a first instruction, so as to drive the second movable plate to move, so as to perform a folding or unfolding operation of the device under test.

[0058] In the present application, the folding / unfolding operation of the folding device is realized by driving the motor to rotate to drive the opening and closing device to move. The motor may be a servo motor, which has the characteristics of fast response, small electromechanical time constant, high linearity, etc., and can convert the received electrical signal into an angular displacement or angular velocity output on the motor shaft.

The visual processing device is arranged above the first rack.

[0061] In the present application, the box structure of the detection equipment is simply set up, which can avoid mechanical noise interference or other influences on the detection process caused by the detection device itself and the external environment as much as possible, making the detection data more accurate and reliable.

[0062] In another possible implementation manner of the first aspect, the detection system further includes a sound insulation device, and the sound insulation device is disposed on an inner wall of the box structure.

[0063] In the present application, in order to make the collected audio data more reliable, a sound insulation device can also be set on the inner wall of the box structure of the detection equipment. The sound insulation device can isolate the environmental noise outside the box structure to improve the accuracy and reliability of the audio data.

[0064] In another possible implementation manner of the first aspect, the box structure includes a rectangular structure or a cylindrical structure.

[0065] In the present application, the box structure of the detection equipment is simply set up, which can avoid mechanical noise interference or other influences on the detection process caused by the detection device itself and the external environment as much as possible, making the detection data more accurate and reliable.

Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0104] As technology matures, more and more users are beginning to pay attention to foldable screen devices, such as foldable screen mobile phones, foldable screen tablets, etc. Foldable screen devices refer to electronic devices that use hinges (or hinges) to fold the screen inward (inward folding) or outward (outward folding). The states of foldable screen devices include fully folded state, hovering state, and fully unfolded state.

[0105] Although foldable screen devices can better meet users' demands for product functional design and appearance, the reliability and durability of foldable screen mobile phones have become a topic of concern because the screen and hinge of foldable screen devices need to be folded frequently. Among them, abnormal sound detection and / or virtual position detection of foldable screen devices are typical types of device reliability detection.

[0106] Abnormal noise detection of folding screen devices refers to the folding screen devices that use hinges to achieve screen folding. Due to the problems of the hinge components (mechanical structure), abnormal noise may occur during the opening and folding process of the folding screen device, so abnormal noise detection is required. The commonly used abnormal noise detection method is for the testing engineer to check the location of the abnormal noise through hearing and experience. Manual detection will be affected by the subjective factors and experience of the testing engineer, resulting in unreliable abnormal noise detection data. For the abnormal noise detection of large quantities of folding devices, this manual detection method has extremely low detection efficiency.

[0107] In an embodiment of the present application, a detection system for a folding device is provided. For example, Figure 1 A structural schematic diagram of a detection system is given. The detection system includes a control device, an audio processing device, an opening and closing device, and a motion device. The motion device is connected to the opening and closing device, and the device under test is placed in the opening and closing device. The motion device drives the opening and closing device to move, and performs a folding or unfolding operation on the device under test. The control device is communicatively connected with the audio processing device, the motion device, and the opening and closing device. The control device sends control instructions to the motion device, the audio processing device, and the opening and closing device respectively, and obtains detection data generated by the device under test during the folding or unfolding operation. The detection data includes an audio detection value, and the audio detection value can be used for abnormal sound detection.

[0108] That is to say, the audio processing device in the detection system provided in the embodiment of the present application can be used to obtain audio detection data of the folding device during the folding / unfolding process, which can be used to detect abnormal sounds of the folding device and automatically collect audio detection data. The detection data is relatively accurate and reliable, and can provide effective data support for abnormal sound analysis of the equipment.

[0109] Reliability testing of foldable screen devices also includes testing in other dimensions, such as virtual position detection.

[0110] The virtual position detection of the folding screen device includes, when the folding screen device is unfolded and in a hovering state, applying a push-pull force to the fixed position of the folding screen device to detect the deformation of the folding screen device; and, when the folding screen device is opened and folded, detecting the deformation of the folding screen device. The commonly used virtual position detection method is to fix the folding screen device at a position, and when the folding screen device is unfolded and in a hovering state, manually apply a force to the fixed position of the folding part of the folding screen device to observe the deformation between the folding parts of the folding screen device. Alternatively, the folding screen device is unfolded and fixed at a position of the device, and a device of the device applies a force to the fixed position of the folding screen device, and the detection engineer observes the deformation of the folding screen device. Whether it is manual detection or semi-manual detection, it will be affected by the subjective factors and experience of the detection engineer. The data of the virtual position detection is manual perception data, there is no objective quantitative data, and the detection data is unreliable. Moreover, for the virtual position detection of a large number of folding devices, the manual detection or semi-manual detection methods also have the problem of low detection efficiency.

[0111] Based on the analysis of various actual usage scenarios of folding screen devices and the survey of usage data of folding screen devices, there are other reliability parameters that are of concern in the scenario of using folding screen devices. For example, during the opening and folding process of the folding screen device, the folding part may be out of sync, so the synchronization of the folding part of the folding screen device can be detected in order to optimize the synchronization of the folding part. There are also traditional methods in which the detection engineer uses a protractor to measure the synchronization of the folding part of the device. Similar to the above detection method, this manual detection method has the problem of no objective quantitative data and large detection data errors. In addition, during the opening and closing process of the folding screen device, users are more concerned about the opening and closing feel and ease of operation of the folding screen device. Then, the opening and closing force of the folding screen device can be detected in order to optimize the opening and closing force of the folding screen device.

[0112] Currently, equipment reliability testing for foldable screen devices is often targeted at testing a reliability parameter, such as abnormal noise detection or virtual position detection. This type of equipment reliability testing relies on manual or semi-manual testing, and has problems such as unreliable data and low testing efficiency.

[0113] In addition, there is currently no integrated testing method for multiple reliability parameters of folding screen devices. The device reliability testing of folding screen devices is not comprehensive enough and cannot meet the needs of multiple reliability parameter testing dimensions of folding screen devices.

[0114] The detection system provided in the embodiment of the present application may include a visual processing device in addition to an audio processing device, an opening and closing device, a motion device, and a control device. The visual processing device can be used to collect detection images of the folding device during the folding / unfolding process, and the detection images can be used to detect the synchronization of the folding part of the folding device. In addition, a torque sensor can be deployed in the opening and closing device to collect the torque detection value of the opening and closing device through the torque sensor, and the torque detection value can be used to perform virtual position detection analysis and opening and closing force analysis of the folding device. In this way, the detection system provided in the embodiment of the present application can realize the integrated detection of multiple reliability parameters in a detection process, greatly improving the efficiency of reliability detection of the folding device.

[0146] Taking the control device being deployed in an electronic device, the electronic device being a personal computer as an example, Figure 3 A schematic diagram of a detection system for a folding device is given. The detection system includes an electronic device, in which a control device 01 is deployed; the detection system also includes a detection device, in which a visual processing device 05, an audio processing device 04, an opening and closing device 03 and a motion device 02 are included.

[0147] The electronic device can be connected to each device in the detection device through wireless or wired communication.

[0148] For example, Figure 3 A schematic diagram illustrating a more detailed detection system is given. Figure 4A multi-dimensional schematic diagram of the detection equipment in the detection system is given, including Figure 4 The front view shown in (a) is as follows: Figure 4 The side view shown in (b) and Figure 4 (c) is a top view shown. Figure 5 A schematic diagram illustrating a relatively simple detection device is given.

[0149] Combination Figure 3-Figure 5 The structure of the detection system is introduced below. The detection system includes a detection device and an electronic device with a control device deployed. The detection device is a box structure, which can be Figure 3 The rectangular structure shown in the figure may also be a cylindrical structure or other special-shaped structures in other possible implementations. The box structure may be a semi-enclosed structure with a door or a window. When the door or the window is open, the device under test can be placed in the opening and closing device or removed from the opening and closing device through the door or the window; when the door or the window is closed, the box structure presents a closed structure.

[0150] like Figure 3 As shown, the visual processing device 05 is arranged on the top of the box structure of the detection device. For example, the visual processing device 05 can be arranged at the geometric center position of the top of the box structure, or the visual processing device 05 can be arranged at any position on the top of the box structure. The visual processing device 05 may include a camera, and the camera is used to collect images within its field of view. In this embodiment, the opening and closing device 03 is within the field of view of the camera, and the camera can collect the detection image of the device under test placed on the opening and closing device. In some embodiments, the visual processing device may include one or more cameras.

[0151] like Figure 3 As shown, the opening and closing device 03 can be arranged on the first placement rack in the middle of the box structure. A folding device can be placed in the opening and closing device 03. The opening and closing device 03 is connected to the motion device 02. When the motion device 02 moves, the opening and closing device 03 can be driven to move, thereby realizing the unfolding / folding operation of the placed folding device.

[0152] like Figure 5 As shown, the opening and closing device 03 includes a fixed center 031, a first fixed plate 032, a second movable plate 033, a rotating disk 034 and a torque sensor 035. The first fixed plate 032 is connected to the fixed center 031, the second movable plate 033 is connected to the rotating disk 034, and the first fixed plate 032 and the second movable plate 033 are connected via a hinge 036. When the motion device 02 drives the rotating disk 034 to rotate, the second movable plate 033 can be driven to move, while the first fixed plate 032 remains stationary.

[0153] For example, reference Figure 6A schematic diagram of the placement of a folding device is given. The folding device under test includes a first folding portion 11 and a second folding portion 12 connected by a rotating shaft 13 (or hinge). When the folding device is placed in the opening and closing device, the first folding portion 11 of the folding device is fixed to the first fixed plate 031 and fits with the first fixed plate 032. The second folding portion 12 of the folding device is fixed to the second movable plate 033 and fits with the second movable plate 033. The rotating shaft 13 of the folding device fits with the hinge 036 of the opening and closing device.

[0154] In this embodiment, the folding device is fixed to the opening and closing device, and the first folding part of the folding device can be fixed to the first fixed plate by magnetic attraction, and the second folding part of the folding device can be fixed to the second movable plate by magnetic attraction. Alternatively, the first folding part of the folding device can be fixed to the fixed structure of the first fixed plate, and the second folding part of the folding device can be fixed to the fixed structure of the second movable plate. The fixing structure can be a buckle structure. This embodiment does not limit the specific method of fixing the folding device to the opening and closing device.

[0155] In this embodiment, if Figure 3-Figure 6 As shown in any of the schematic diagrams, the motion device 02 is disposed below the opening and closing device 03 and is connected to the rotating disk 034 in the opening and closing device 03. The motion device 02 moves to drive the rotating disk 034 to rotate, and the rotating disk 034 drives the second movable plate 033 to move, while the first fixed plate 032 remains stationary. When the folding device is placed in the opening and closing device 03, the second movable plate 033 moves, while the first fixed plate 032 remains stationary, thereby realizing the unfolding and folding operation of the folding device.

[0156] In one implementation, Figure 5 or Figure 6 As shown, the torque sensor 035 in the opening and closing device 03 is connected to the first fixed plate 032 and the second movable plate 033, and is used to collect torque data (torque detection value) generated by the first fixed plate 032 and the second movable plate 033 during the unfolding and folding process.

[0157] In this embodiment, the motion device at least includes a motor and a motor drive. Exemplarily, the motor can be a servo motor, and the corresponding motor drive is a servo motor drive. The servo motor can control the speed, and the position accuracy is relatively accurate. It can convert the voltage signal into torque and speed to drive and control the rotation of the rotating disk. The servo motor has the characteristics of fast response, small electromechanical time constant, and high linearity. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. In the process of the motor driving the rotating disk and the second movable plate to move, the torque sensor can collect the torque data generated between the second movable plate and the first fixed plate, and the control device can obtain the torque data (torque detection value) collected by the torque sensor.

[0158] In this embodiment, the moving device can be arranged on the first placing rack of the box structure, or the moving device can also be arranged on the third placing rack of the box structure. The third placing rack is located below the first placing rack.

[0159] like Figure 3-Figure 6 As shown in any of the schematic diagrams, the opening and closing device 03 includes a hinge 036. The audio processing device 04 is used to detect the audio detection value generated by the hinge 036 of the folding device during the unfolding / folding process. Therefore, the audio processing device 04 can be set near the hinge 036 of the motion device (first orientation). Figure 3-Figure 6 As shown in any of the schematic diagrams, the audio processing device 04 can be arranged behind the hinge 036. The audio processing device 04 can be arranged on a second placement rack of the box structure of the detection device, and the second placement rack is arranged on an inner wall of the box structure, which can be the inner wall corresponding to the rear of the hinge of the opening and closing device 03.

[0160] The audio processing device at least includes a microphone for collecting audio signals. The microphone may be a high-precision microphone. The microphone is an energy conversion device that converts sound signals into electrical signals. The control device may use audio data (audio detection value) through the microphone.

[0161] In this embodiment, in order to make the collected audio data more reliable, a sound insulation device can also be set on the inner wall of the box structure of the detection equipment. The sound insulation device can isolate the environmental noise outside the box structure to improve the accuracy and reliability of the audio data.

[0162] In some feasible embodiments, a soundproof cover may be provided for other detection devices in the detection device other than the audio processing device to reduce noise interference caused by movement or data collection of other detection devices inside the detection device.

[0163] After the folding device to be tested is placed on the opening and closing device, the electronic device (control device) enables the moving device by communicating with the moving device, and the moving device drives the second moving plate of the opening and closing device to move, thereby realizing the unfolding and folding operation of the folding device.

[0164] During the unfolding / folding operation of the folding device, the electronic device may acquire a detection image of the folding device captured by the visual processing device based on a preset frequency or, when the folding device is detected to be unfolded to a specified angle, by communicating with the visual processing device. The electronic device may further perform target detection on the detection image to determine the angle deviation of the first folding part and the second folding part of the folding device relative to the rotation axis in the detection image, thereby obtaining a synchronization detection result of the first folding part and the second folding part. In some optional implementations, the electronic device may display the synchronization detection result of the folding device indicated by the detection image on a display screen.

[0165] During the unfolding and folding operation of the folding device, the electronic device can acquire the audio detection data (audio detection value) during the unfolding and folding process of the folding device based on a preset frequency, or when the folding device is detected to be unfolded to a specified angle, by communicating with the audio processing device, and obtain the corresponding audio detection value curves at different angles. Thus, the abnormal sound detection result of the folding device represented by the audio detection value curve can be displayed on the display screen.

[0166] During the unfolding and folding operation of the folding device, the electronic device can obtain the torque detection data (torque detection value) collected by the torque sensor based on a preset frequency, and obtain the corresponding torque detection value curve at different angles. Therefore, the opening and closing force detection result of the folding device represented by the torque detection value curve can be displayed on the display screen. Based on the torque detection value curve, the slope change of the curve can also be calculated to obtain the virtual position detection result during the unfolding and folding operation of the folding device.

[0167] In some embodiments, the electronic device may also display the detection process information of the folding device on the display screen, for example, displaying the detection progress on the display screen, the detection data collected corresponding to the detection progress, and so on.

[0168] The above embodiment illustrates the detection system by taking an example in which the control device is deployed in an electronic device independent of the detection device, and the electronic device communicates with the opening and closing device, motion device, visual processing device and audio processing device in the detection device through wired communication or wireless communication to obtain the detection data collected by each device and output the corresponding detection results on the display screen of the electronic device.

[0169] In some other feasible implementations, the control device may also be disposed inside the detection device, that is, inside the box structure of the detection device. Figure 7 As shown, Figure 7 A structural schematic diagram of another detection system is given. By way of example, the control device 01 may be arranged at the bottom of the box structure of the detection device.

[0170] In some embodiments, the detection device may also include a display screen, which may be disposed on the outer surface of any side of the box structure. The control device is in communication with the display screen, and may display on the display screen the synchronization detection result of the folding device indicated by the detection image, the abnormal sound detection result of the folding device represented by the audio detection value curve, the opening and closing force detection result of the folding device represented by the torque detection value curve, and the virtual position detection result of the folding device during the unfolding and folding operation, etc. In some embodiments, the control device may also display the detection process information of the folding device on the display screen, for example, displaying the detection progress on the display screen, the detection data collected corresponding to the detection progress, etc.

[0171] The visual processing device in the detection system provided in the embodiment of the present application obtains the detection image of the folding device during the folding / unfolding process, which is used to perform synchronization detection of the folding device; the audio processing device of the detection system obtains the audio detection data of the folding device during the folding / unfolding process, which is used to perform abnormal noise detection of the folding device; the opening and closing device of the detection system obtains the torque detection data of the folding device during the folding / unfolding process, which is used to perform opening and closing force detection and virtual position detection of the folding device. An integrated detection system based on the integration of multiple acquisition devices automatically collects detection data of multiple types of reliability parameters, and the detection data is relatively accurate and reliable; and the detection system can be applied to the equipment detection of multiple reliability parameters of a large number of folding devices, which greatly improves the efficiency of equipment reliability detection. In addition, it can also provide effective data support for data analysis of equipment reliability.

[0172] The above embodiments introduce different modes of the detection system. Combined with the above specific examples, the control device is used as the execution subject to introduce the method for obtaining the detection data of the folding device under test during the detection process provided by the embodiment of the present application. Among them, the detection process of the folding device generally includes the device initialization stage, the folding device boarding stage, the folding device detection stage from complete folding to complete unfolding, the folding device detection stage from complete unfolding to complete folding, the folding device detection stage within the specified unfolding angle range, and the folding device disembarking stage.

[0173] refer to Figure 8 , Figure 8 A scene interaction diagram of a method for acquiring detection data is given, including:

[0174] S201, initializing the detection device used for detection in the detection system.

[0175] The detection device used for detection in the detection system may include a visual processing device, an audio processing device, an opening and closing device, and a motion device. In this embodiment, the control device may send initialization instructions to the detection devices respectively, so that each detection device performs its own device initialization processing respectively.

[0176] For example, the control device sends an initialization instruction to the visual processing device, and the visual processing device resets the shooting parameters of the camera to the default values. For example, the shooting magnification is initialized to 1x, the shooting aperture is initialized to the default value, the exposure time is initialized to the default value, and so on. In addition, optionally, the visual processing device may also include a local memory for real-time storage of the collected detection images. After the visual processing device receives the initialization instruction, the visual processing device may also clear the detection images in the local storage space to release more storage space for storing the detection images of the next detection device.

[0177] For example, the control device sends an initialization instruction to the audio processing device, and the audio processing device resets the parameters of the microphone to the default values. For example, the volume of the microphone is initialized to the default value, the white noise of the microphone is initialized to the default value, the gain of the microphone is initialized to the default value, and so on. In addition, optionally, the audio processing device may also include a local memory for real-time storage of the collected audio data. After the audio processing device receives the initialization instruction, the audio processing device may also clear the audio data in the local storage space to release more storage space for storing the audio data of the next detection device.

[0178] For example, the control device sends an initialization instruction to the opening and closing device, and the opening and closing device resets the parameters of the torque sensor to default values, such as initializing the torque of the torque sensor to 0, and so on.

[0179] For example, the control device sends an initialization instruction to the motion device, and the motion device resets the parameters of the motor to default values, such as initializing the stroke of the motor to 0, and so on.

[0180] Alternatively, in some embodiments, each detection device may be directly initialized. For example, each detection device may be directly reset (reset / initialized) by using a reset button (if any) of each detection device, so that the parameters of the detection device are initialized to default values. This embodiment does not limit the specific implementation method of device initialization of each detection device.

[0181] In this embodiment, the control device performs device initialization, which may refer to the control device ending the acquisition process of the detection data of a folding device 1 under test, and starting the acquisition process of the detection data of a new folding device 2 under test. The control device may organize the detection data of the folding device 1 and the detection results indicated by the detection data, and store the data in a designated storage space.

[0182] In some embodiments, the control device may clear the data displayed on the display screen and prepare to display new detection data or detection results of the folding device 2 under test.

[0183] S202, placing the folding device to be tested in the opening and closing device of the detection system.

[0184] In this embodiment, the folding device can be placed in the opening and closing device of the detection system manually or by a mechanical arm to complete the loading stage of the folding device under test.

[0185] After the folding device under test is placed on the opening and closing device, the control device can simultaneously record the device identification of the folding device under test. Exemplarily, the device identification can be a unique identifier such as the device number, device serial number, or preset device code of the folding device. The detection device is placed on the opening and closing device, and the detection device is within the field of view of the camera of the visual processing device.

[0186] In some embodiments, the opening and closing device may further include a sensor for detecting whether a folding device is placed. For example, the opening and closing device may include a pressure sensor, an infrared sensor, a light sensor, and the like. Among them, the pressure sensor is used to sense the pressure signal and can convert the pressure signal into an electrical signal. In some embodiments, the pressure sensor can be arranged inside the first fixed plate and the second movable plate of the opening and closing device to detect whether a folding device is placed in the first fixed plate and / or the second movable plate. Specifically, the control device can obtain the pressure data collected by the pressure sensor, or obtain the distance data collected by the infrared sensor, to determine whether a folding device has been placed in the opening and closing device.

[0187] When it is determined that the folding device is placed, a detection operation of the folding device may be triggered.

[0188] S203: The control device determines that the opening and closing device places the folding device to be tested, and sends a control instruction to each detection device to perform a detection operation of the folding device and obtain detection data of the folding device from each detection device.

[0189] In this embodiment, the detection operation of the folding device includes the detection operation of the folding device from completely folded to completely unfolded, the detection operation of the folding device from completely unfolded to completely folded, and the detection operation of the folding device within a specified unfolding angle range.

[0190] Specifically, when the folding device is placed on the opening and closing device, the opening and closing device can restore the state to the fully folded state. At this time, the folding device is also in a fully folded state. The control device sends a control instruction to the motion device, and the motion device drives the opening and closing device to gradually unfold from the fully folded state (0°) until it is in a fully unfolded state (180°). The control device sends a control instruction to the visual processing device, the audio processing device, and the torque sensor of the opening and closing device to obtain detection data such as detection images, audio detection values, and torque detection values ​​during the process of the folding device unfolding from 0° to 180°.

[0191] After the opening and closing device is in the fully extended state (180°), the folding device is also in the fully extended state. The control device sends a control instruction to the motion device, and the motion device drives the opening and closing device to gradually fold from the fully extended state (180°) until it is in the fully folded state (0°). The control device sends a control instruction to the visual processing device, the audio processing device, and the torque sensor of the opening and closing device to obtain detection data such as detection images, audio detection values, and torque detection values ​​during the process of the folding device closing from 180° to 0°.

[0192] The control device can also obtain the detection data generated by the folding device within the specified folding angle range to detect the corresponding reliability parameters. For example, the control device sends a control instruction to the motion device, and the motion device drives the opening and closing device to unfold the folding device to the first specified angle. For example, the first specified angle can be 80°, 85°, 90°, etc.

[0193] For example, when the unfolding angle of the opening and closing device / folding device is 80°, the control device sends a control instruction to the motion device, and the motion device drives the opening and closing device to unfold the folding device to a second specified angle. Exemplarily, the second specified angle can be 100°, 105°, 110°, etc. For example, the control device sends a control instruction to the visual processing device, the audio processing device, and the torque sensor of the opening and closing device to obtain detection data such as detection images, audio detection values, and torque detection values ​​during the process of the folding device unfolding from 80° to 100°.

[0194] Similarly, when the unfolding angle of the opening and closing device / folding device is 100°, the control device sends a control instruction to the motion device, and the motion device drives the opening and closing device to fold the folding device to the first specified angle. Exemplarily, the second specified angle can be 80°. The control device sends a control instruction to the visual processing device, the audio processing device, and the torque sensor of the opening and closing device to obtain detection data such as detection images, audio detection values, and torque detection values ​​during the folding process of the folding device from 100° to 80°.

[0195] Specifically, taking the detection stage in the process of the folding device from being completely folded to being fully unfolded as an example, the control device determines that the folding device is placed on the opening and closing device, and when the opening and closing device restores the state to the fully folded state, the control device sends a control instruction to each detection device to obtain the detection data generated by the folding device during the unfolding and folding process, including:

[0196] S2031. The control device sends a first instruction to the motion device.

[0197] In this embodiment, the control device may send a first instruction to the motor driver in the motion device, wherein the first instruction may carry motion parameters, such as the rotation speed and frequency of the motor.

[0198] S2032: The motion device rotates at a first speed in response to the first instruction, driving the opening and closing device to move, thereby performing an unfolding and folding operation of the folding device under test.

[0199] In this embodiment, after receiving the first instruction, the motor driver in the motion device controls the motor in the motion device to rotate accordingly based on the motion parameters indicated by the first instruction. For example, the first instruction indicates that the rotation speed is a first speed. The motor driver responds to the first instruction and controls the motor to rotate at the first speed. The motor is connected to the rotating disk of the opening and closing device, and the rotating disk of the opening and closing device is connected to the second movable plate. The rotation of the motor drives the rotating disk to rotate, and the rotation of the rotating disk drives the second movable plate to move, thereby realizing the unfolding operation of the opening and closing device / folding device.

[0200] S2033. The control device sends a third instruction to the visual processing device.

[0201] In this embodiment, the control device may send a third instruction to the visual processing device, wherein the third instruction may carry shooting parameters, such as shooting frequency.

[0202] S2034. The visual processing device responds to the third instruction and collects detection images at a second frequency.

[0203] In this embodiment, after receiving the third instruction, the visual processing device performs a detection image acquisition operation of the folding device based on the shooting parameters indicated by the third instruction. For example, the third instruction indicates that the shooting frequency is the second frequency. In response to the third instruction, the visual processing device acquires the detection image of the folding device at the second frequency.

[0204] In some optional embodiments, the motion device can also communicate directly with the visual processing device. When the motion device determines to rotate to a specified angle, the motion device (motor drive) can send an image acquisition instruction to the visual processing device. The visual processing device acquires the detection image of the folding device at the specified angle and returns the detection image and the corresponding angle detection data to the control device.

[0205] S2035. The visual processing device returns the collected detection image to the control device.

[0206] During the unfolding operation of the opening and closing device / folding device, the visual processing device may acquire detection images of the folding device at various unfolding angles according to the first frequency. For example, the certain frequency may be to acquire the corresponding detection image of the folding device every time the unfolding angle of the folding device is unfolded by 10°. That is, the detection images of the folding device corresponding to 10°, 20°, 30°, ..., 180° are acquired.

[0207] In this embodiment, the visual processing device may return a detection image and detection data of the corresponding angle to the control device after each detection image is collected. Alternatively, the visual processing device may store the detection image in a local memory after collecting a detection image, and return multiple detection images and detection data of the corresponding angle to the control device after collecting multiple detection images. That is, the frequency at which the visual processing device sends detection data to the control device is not limited.

[0208] In some other feasible ways, the control device can obtain the collected detection images and the detection data of the corresponding angle from the local memory of the visual processing device at a certain frequency. This embodiment does not limit the frequency of the control device obtaining the detection data.

[0209] S2036: The control device sends a second instruction to the audio processing device.

[0210] In this embodiment, the control device may send a second instruction to the audio processing device, wherein the second instruction may carry acquisition parameters, such as the acquisition parameters may include audio acquisition frequency and the like.

[0211] S2037. The audio processing device collects audio detection values ​​at the first frequency in response to the second instruction.

[0212] In this embodiment, after receiving the second instruction, the audio processing device performs an operation of collecting the audio detection value of the folding device based on the collection parameters indicated by the second instruction. For example, the second instruction indicates that the audio collection frequency is the first frequency. In response to the second instruction, the audio processing device collects the audio detection value of the folding device at the first frequency.

[0213] In some optional embodiments, the motion device can also communicate directly with the audio processing device. When the motion device determines to rotate to a specified angle, the motion device (motor drive) can send an audio collection instruction to the audio processing device. The audio processing device collects the audio detection value of the folding device at the specified angle, and returns the audio detection value and the corresponding angle detection data to the control device.

[0214] S2038. The audio processing device returns the collected audio detection value to the control device.

[0215] During the unfolding operation of the opening and closing device / folding device, the audio processing device may obtain the audio detection value of the folding device at each unfolding angle according to the first frequency. For example, the certain frequency may be to obtain the corresponding audio detection value of the folding device every time the unfolding angle of the folding device is unfolded by 5°. That is, the audio detection values ​​of the folding device corresponding to 5°, 10°, 15°, ..., 180° are obtained.

[0216] In this embodiment, the audio processing device may return an audio detection value and detection data of the corresponding angle to the control device after each audio detection value is collected. Alternatively, the audio processing device may store the audio detection value in a local memory after collecting an audio detection value, and return multiple audio detection values ​​and detection data of the corresponding angle to the control device after collecting multiple audio detection values. That is, the frequency at which the audio processing device sends detection data to the control device is not limited.

[0217] In some other feasible ways, the control device can obtain the collected audio detection values ​​and the detection data of the corresponding angle from the local memory of the audio processing device at a certain frequency. This embodiment does not limit the frequency of the control device obtaining the detection data.

[0218] S2039. The control device sends a fourth instruction to the opening and closing device.

[0219] In this embodiment, the control device may send a fourth instruction to the torque sensor in the opening and closing device, wherein the fourth instruction may carry acquisition parameters, such as the acquisition parameters may include the torque acquisition frequency, etc.

[0220] S20310. The opening and closing device collects torque detection values ​​at a third frequency in response to the fourth instruction.

[0221] In the process of realizing the unfolding operation of the opening and closing device / folding device by the rotation of the motor driving the rotating disk to rotate, and the rotation of the rotating disk driving the second movable plate to move, after receiving the fourth instruction, the torque sensor performs the acquisition operation of the torque detection value of the folding device based on the acquisition parameters indicated by the fourth instruction. For example, the torque detection value corresponding to each unfolding angle is obtained according to the third frequency indicated by the fourth instruction. For example, the third frequency can be to obtain the corresponding torque detection value when the unfolding angle of the folding device is unfolded by 5°. That is, the torque detection values ​​corresponding to 5°, 10°, 15°, ..., 180° are obtained.

[0222] S20311. The opening and closing device returns the collected torque detection value to the control device.

[0223] In this embodiment, the torque sensor may return a torque detection value and detection data of the corresponding angle to the control device after each torque detection value is collected. Alternatively, the torque sensor may store the torque detection value in a local memory after collecting a torque detection value, and return multiple torque detection values ​​and detection data of the corresponding angle to the control device after collecting multiple torque detection values. That is, the frequency at which the torque sensor sends detection data to the control device is not limited.

[0224] In some other feasible ways, the control device may obtain the collected torque detection value and the corresponding angle detection data from the torque sensor at a certain frequency. This embodiment does not limit the frequency at which the control device obtains the detection data.

[0225] In the above embodiments, S2031-S20311 is explained by taking the detection stage in the process (completely unfolding process) of the folding device from complete folding (0°) to complete unfolding (180°) as an example. It can be understood that when the control device determines that the opening and closing device / folding device is in a fully unfolded state, it can send corresponding control instructions to the motion device, the opening and closing device, the visual processing device and the audio processing device respectively to obtain the detection data of the process (completely folding process) of the folding device from complete unfolding (180°) to complete folding (0°). Also, for the acquisition of detection data within some specified angle ranges, when the control device determines that the opening and closing device / folding device is at a first specified angle, the control device can send corresponding control instructions to the motion device, the opening and closing device, the visual processing device and the audio processing device respectively, to obtain the detection data of the folding device in the process from the first specified angle (such as 80°) to the second specified angle (such as 100°) (unfolding and hovering process); and, when the control device determines that the opening and closing device / folding device is at a second specified angle, the control device can send corresponding control instructions to the motion device, the opening and closing device, the visual processing device and the audio processing device respectively, to obtain the detection data of the folding device in the process from the second specified angle (such as 100°) to the first specified angle (such as 80°) (folding and hovering process).

[0226] In the different unfolding processes / folding processes of the above folding device, the method of the control device issuing control instructions to each detection device and acquiring detection data is similar, which will not be described in detail in this embodiment.

[0227] S204: The control device processes the received detection data to obtain a detection result of the folding device under test.

[0228] In this embodiment, the control device can obtain the synchronization detection result of the first folding part and the second folding part of the folding device based on the detection image of the folding device. The control device can obtain the abnormal sound detection result of the folding device based on the audio detection value of the folding device. The control device can obtain the opening and closing force detection result and the virtual position detection result of the folding device based on the torque detection value of the folding device.

[0229] For the synchronization detection result, specifically, the control device can obtain the detection image of the folding device at various angles (specified angles) during the unfolding / folding operation of the opening and closing device / folding device. Fig. 9 A schematic diagram of detecting an image is given.

[0230] refer to Fig. 9 (a) in FIG. 1 shows a schematic diagram of a folding device that is a vertically folding folding screen mobile phone. A detection image corresponding to the folding device is Fig. 9As shown in (b) in the figure. The detection image of the folding device is used to detect the synchronization between the first folding part and the second folding part of the folding device. Therefore, after the control device obtains at least one detection image, it can perform target recognition on the detection image, identify the first folding part, the second folding part, and the rotating shaft of the folding device in the detection image; and obtain the first edge of the first folding part, the second edge of the second folding part, and the third edge of the rotating shaft. Based on the first edge and the third edge, obtain the first angle between the first folding part and the rotating shaft (such as Fig. 9 Based on the second edge and the third edge, obtain the second angle between the second folded portion and the rotation axis (such as Fig. 9 Corner 2) shown in (b).

[0231] In this embodiment, other edge lines parallel to the first edge corresponding to the first folded portion, other edge lines parallel to the second edge corresponding to the second folded portion, and other edge lines parallel to the third edge corresponding to the rotation axis can be obtained to respectively calculate the first angle and the second angle. This embodiment does not limit the specific position of the edge line for calculating the angle.

[0232] The first angle represents the angle between the first folding part and the rotating shaft during the unfolding / folding process of the folding device; the second angle represents the angle between the second folding part and the rotating shaft during the unfolding / folding process of the folding device. The smaller the angle deviation between the first angle and the second angle, the higher the synchronization between the first folding part and the second folding part. Based on this, the control device can obtain the detection result of the synchronization between the first folding part and the second folding part of the folding device by the angle deviation between the first angle and the second angle of the folding device at different unfolding angles.

[0233] For example, Fig.10 A schematic diagram of synchronization detection results of a first folding part and a second folding part of a folding device is provided. Fig.10 The line graph shown in the figure shows the deviation of the first angle and the second angle at different folding angles. Fig.10 As shown in the figure, the unfolding process is represented by a positive angle). The angle deviation between the first angle and the second angle is 0. During the unfolding process of the folding device from 0° to 120°, the angle deviation between the first angle and the second angle gradually increases to about 2.4, and the synchronization is poor. During the unfolding process of the folding device from 120° to 170° or even to 180°, the angle deviation between the first angle and the second angle gradually decreases until it decreases to 0, and the synchronization is good. When the folding device is in a fully unfolded state (such as Fig.10In the process of folding the folding device from 140° to 110°, the angle deviation between the first angle and the second angle remains unchanged at 2.4, and the synchronization is poor; in the process of folding the folding device from 110° to 0°, the angle deviation between the first angle and the second angle gradually decreases until it is reduced to 0, and the synchronization is good.

[0234] The control device obtains the angle deviation data (synchronization detection result) of the folding device and can display the synchronization detection result on the display screen. Optionally, the control device can store the synchronization detection result in a designated storage space to facilitate subsequent analysis of the synchronization detection result.

[0235] For the abnormal sound detection result, specifically, the control device can obtain the audio detection value of the folding device at each angle (specified angle) during the unfolding / folding operation of the opening and closing device / folding device. Fig.11 A curve diagram of abnormal noise detection results is given.

[0236] For example, Fig.11 The curve diagram shown in the figure expresses the decibel level generated by the rotating shaft of the folding device at different folding angles. For example, when the folding device is in a fully folded state (such as Fig.11 When the folding device is unfolded from 0° to 140°, the decibel generated by the folding device's rotating shaft is about 25dB. When the folding device is unfolded from 0° to 140°, the decibel generated by the folding device's rotating shaft is maintained in the range of 20dB-30dB. When the folding device is unfolded from 140° to 150°, the decibel generated by the folding device's rotating shaft increases to 33dB, and a small abnormal noise is generated in this process. When the folding device is unfolded from 150° to 180°, the decibel generated by the folding device's rotating shaft decreases and is maintained in the range of 20dB-30dB, and the abnormal noise is reduced. When the folding device is in a fully unfolded state (such as Fig.11 In the process of folding the folding device from 180° to 130°, the decibel generated by the rotating shaft of the folding device increases from the initial 25dB to about 51dB, and the decibel increases unstably at 170°, 160°, 140°, and 130°, respectively. In this process, the abnormal noise problem is serious. In the process of folding the folding device from 130° to 0°, the decibel generated by the rotating shaft of the folding device gradually decreases from 36dB to the range of 20dB-30dB, and the abnormal noise is reduced.

[0237] In the abnormal sound detection results, the folding angle corresponding to the audio detection value being greater than the preset decibel threshold is the angle at which the abnormal sound is generated when the folding screen device is folded / unfolded.

[0238] The control device obtains the audio detection data (abnormal sound detection result) of the folding device and can display the abnormal sound detection result on the display screen. Optionally, the control device can store the abnormal sound detection result in a designated storage space to facilitate subsequent analysis of the abnormal sound detection result.

[0239] For the abnormal sound detection result, specifically, the control device can obtain the torque detection value of the folding device at each angle (specified angle) during the unfolding / folding operation of the opening and closing device / folding device. For example, Fig.12 A curve diagram of the opening and closing force detection results is given.

[0240] For example, Fig.12 The curve diagram shown shows the torque detection values ​​of three different folding devices at different folding angles. The increase and decrease trends of the torque detection values ​​generated by the three different folding devices during the whole process are roughly the same, and the folding device 1 is used as an example to illustrate.

[0241] When the folding device 1 is in a fully folded state (such as Fig.12 0° as shown), the torque presents a first direction. The torque detection value of the folding device 1 in the first direction is 0.5Nm. In the process of the folding device 1 unfolding from 0° to 5°, the torque detection value of the folding device 1 in the first direction increases to 2.1Nm. At this time, it is more difficult to open the folding device 1. In the process of the folding device 1 unfolding from 5° to 35°, the torque detection value of the folding device 1 in the first direction is maintained in the range of 2.0Nm-2.5Nm. In the process of the folding device 1 unfolding from 35° to 120°, the torque detection value of the folding device 1 gradually decreases to about 1.8Nm, the torque detection value decreases, and the force required to open the folding device 1 decreases. In the process of the folding device 1 unfolding from 120° to 170°, the torque detection value of the folding device 1 gradually decreases to about 0Nm, and the torque detection value decreases; until the folding device 1 unfolds from 170° to 180°, the folding device presents an opening rebound force, at which time, the torque detection value decreases to about -0.1Nm.

[0242] When the foldable device 1 is in a fully unfolded state (such as Fig.12The torque of the folding device 1 in the second direction is about 0.2 Nm. During the folding process of the folding device 1 from 180° to 170°, the torque of the folding device 1 in the second direction increases to about 2.2 Nm (the negative sign of the torque detection value represents the second direction). During the folding process of the folding device 1 from 170° to 0°, the torque of the folding device 1 gradually decreases until it decreases to about 0.2 Nm. The force required to fold the folding device 1 gradually decreases.

[0243] The control device obtains the torque detection value (opening and closing force detection result) of the folding device, and can display the opening and closing force detection result on the display screen. Optionally, the control device can store the opening and closing force detection result in a designated storage space to facilitate subsequent analysis of the opening and closing force detection result.

[0244] For the virtual position detection of the foldable device, the virtual position detection is often performed when the foldable device is in a hovering state. Therefore, the virtual position detection can be performed when the foldable device is in an unfolded hovering state or a folded hovering state.

[0245] Exemplarily, when the control device determines that the opening and closing device / folding device is at the first specified angle, the control device can send corresponding control instructions to the motion device, the opening and closing device, the visual processing device, and the audio processing device, respectively, and can obtain the torque detection value of the folding device in the process from the first specified angle (such as 80°) to the second specified angle (such as 100°) (unfolding and hovering process). And, when the control device determines that the opening and closing device / folding device is at the second specified angle, the control device can send corresponding control instructions to the motion device, the opening and closing device, the visual processing device, and the audio processing device, respectively, to obtain the torque detection value of the folding device in the process from the second specified angle (such as 100°) to the first specified angle (such as 80°) (folding and hovering process). Based on the torque detection value corresponding to the unfolding and hovering process and the torque detection value corresponding to the folding and hovering process, the virtual position detection result is obtained.

[0246] For example, Fig.13 A schematic diagram of the virtual position detection result is given. Fig.13 The curve diagram shown shows the torque detection values ​​at different folding angles when two different folding devices are in a hovering state. The black solid line represents folding device 1, and the dotted line represents folding device 2.

[0247] Take the folding device 1 as an example. During the unfolding and hovering process of the folding device 1, for example, when the folding device 1 is in the 80° hovering state, the torque detection value of the folding device 1 in the first direction is approximately 0 Nm. During the unfolding process of the folding device 1 from 80° to 84°, the torque detection value of the folding device 1 in the first direction increases to 0.11 Nm. During the unfolding process of the folding device 1 from 84° to 100°, the torque detection value of the folding device 1 in the first direction is maintained within the range of 0.11 Nm. That is, during the unfolding process of the folding device 1, there is a point of sudden increase in torque (84°). The unfolding process of the folding device 1 from 80° to 84° can be considered as the first stage, in which the opening and closing force climbs from 0 to a stable state. During the unfolding process of the folding device, the folding device moves with the opening and closing device, and is subjected to the elastic deformation force of the moving plate in the opening and closing device, the elastic deformation force of the folding part, the force generated by the virtual gap of the folding device itself, and the friction force of the rotating shaft itself (the friction force does not reach the maximum friction force at this time). During the process of unfolding the folding device 1 from 84° to 100°, the opening and closing force of the folding device climbs to a stable state, which is the second stage. The force received in this stage includes the friction of the rotating shaft itself (the friction reaches the maximum friction at this time).

[0248] The virtual feel of a folding device is related to the virtual gap of the folding device itself and the elastic deformation of the folding part. The folding screen will rebound when subjected to a small push, and the perception that the hinge is not tight will cause virtual space, resulting in a poor user feel. Therefore, the smaller the force in the first stage (the smaller the deformation and virtual gap), the shorter the time of this stage, the shorter the opening and closing force climbing state, and the lower the virtual degree of the folding device. Fig.13 The greater the slope of the first stage, the lower the degree of virtual position, and the better the user experience of using the folding device.

[0249] Correspondingly, during the folding and hovering process of the folding device 1, when the folding device 1 is in a 100° hovering state, the torque detection value of the folding device 1 is approximately 0.11 Nm, and during the folding process of the folding device 1 from 100° to 94°, the torque detection value of the folding device 1 changes from 0.11 Nm in the first direction to 0.01 Nm in the second direction. During the folding process of the folding device 1 from 94° to 80°, the torque detection value of the folding device 1 in the second direction is maintained within the range of 0.01 Nm. That is, during the folding process of the folding device 1, there is a torque sudden change point (94°). The process of the folding device 1 folding from 100° to 94° can be considered as the first stage, during which the opening and closing force changes from 0.11 Nm in the first direction to 0.01 Nm in the second direction and is in a stable state.

[0250] Compared with folding device 1 and folding device 2, Fig.13It can be seen that the slope of foldable device 1 (bold black solid line) is smaller than the slope of foldable device 2 (bold black dashed line). In other words, the time / expansion angle of foldable device 1 entering the stable state is greater than the time / expansion angle of foldable device 2 entering the stable state. The virtual position of foldable device 2 during the unfolding / folding process is relatively low, and users feel better when using foldable device 2.

[0251] The control device obtains the torque detection value of the folding device (the virtual position detection result in the hovering state), and can display the virtual position detection result on the display screen. Optionally, the control device can store the virtual position detection result in a designated storage space to facilitate subsequent analysis of the virtual position detection result.

[0252] In some embodiments, the detection system may also include other related settings for detecting device reliability parameters. For example, a second motion device may be included, and the second motion device may give the second movable plate a force perpendicular to the first fixed plate, so as to detect the virtual position of the folding part of the folding device in the vertical direction. Alternatively, other corresponding detection devices may be added to perform device detection according to the reliability detection requirements in other scenarios.

[0253] The visual processing device in the detection system provided in the embodiment of the present application obtains the detection image of the folding device during the folding / unfolding process, which is used to perform synchronization detection of the folding device; the audio processing device of the detection system obtains the audio detection data of the folding device during the folding / unfolding process, which is used to perform abnormal noise detection of the folding device; the opening and closing device of the detection system obtains the torque detection data of the folding device during the folding / unfolding process, which is used to perform opening and closing force detection and virtual position detection of the folding device. An integrated detection system based on the integration of multiple acquisition devices automatically collects detection data of multiple types of reliability parameters, and the detection data is relatively accurate and reliable; and the detection system can be applied to the equipment detection of multiple reliability parameters of a large number of folding devices, which greatly improves the efficiency of equipment reliability detection. In addition, it can also provide effective data support for data analysis of equipment reliability.
