[0022] As Figure 1 shown, it is a local structure schematic diagram of an electronic device according to an embodiment of the present application.

[0023] The electronic device comprises a shell, a display module, and a transceiver module 140. The shell is provided with a receiving cavity 150 and an opening communicating with the receiving cavity 150. The display module is at least partially arranged in the receiving cavity 150. The display module comprises a flexible screen 120 and an electromagnetic plate 130 arranged in sequence, and the electromagnetic plate 130 is distributed with coils. The display module can further comprise a glass cover plate 110, which is not limited in the embodiments of the present application. The transceiver module 140 is arranged in the receiving cavity 150, and the transceiver module 140 is used for transmitting electromagnetic signals to the electromagnetic plate 130 or receiving electromagnetic signals transmitted by the electromagnetic plate 130. The display module further comprises a control loop board, and the control loop board is used for controlling the coils on the electromagnetic plate 130 to be powered or to conduct target loops for receiving electromagnetic signals. The control loop board is not shown in the figure. Figure 1

[0024] The display module can be retracted into the receiving cavity 150 or at least partially extended out of the receiving cavity 150 through the opening. In an implementation, the electronic device further comprises a bearing 160, and rotation of the bearing 160 can drive the display module to retract into the receiving cavity 150 or at least partially extend out of the receiving cavity 150 through the opening.

[0025] Therefore, the electronic device provided by the embodiments of the present application can transmit electromagnetic signals to the electromagnetic plate in the electronic device or receive electromagnetic signals transmitted by the electromagnetic plate through the transceiver module in the electronic device, control the coils on the electromagnetic plate to be powered to transmit electromagnetic signals to the transceiver module or to conduct target loops to receive electromagnetic signals transmitted by the transceiver module through the control loop board in the electronic device, and determine the motion characteristics of the display module based on the electromagnetic signals. The present application can detect the motion characteristics of the display module.

[0026] In an implementation, the display module further comprises an electromagnetic shielding cover 170, which is arranged between the electromagnetic plate 130 and the transceiver module 140, and the electromagnetic shielding cover 170 is provided with a through hole opposite to the transceiver module.

[0027] The electromagnetic shielding cover 170 can be made of a material with high magnetic conductivity and electrical conductivity for shielding electromagnetic signals.

[0028] ​Therefore, the electromagnetic shield with the through hole can make the transceiver module and the electromagnetic plate transmit and receive electromagnetic signals, and avoid the magnetic field generated by the electromagnetic plate from interfering with other devices in the electronic device.

[0029] In an implementation manner, the transceiver module 140 can be arranged at a position far from an electronic compass in the electronic device, so as to avoid the electromagnetic signal from interfering with the electronic compass.

[0030] In an implementation manner, the transceiver module 140 can be arranged on a main PCB of the electronic device, or the transceiver module 140 can be arranged on an FPC of the electronic device.

[0031] In an implementation manner, the transceiver module 140 is a transmitting module, which is configured to obtain electric energy and transmit electromagnetic signals to the electromagnetic plate 130. In the case that the transmitting module transmits electromagnetic signals to the electromagnetic plate 130, the control loop board controls the coil on the electromagnetic plate 130 to be conductive to the target loop to receive the electromagnetic signals transmitted by the transceiver module. The control loop board is further configured to detect the magnetic field energy of the coil distributed on the electromagnetic plate 130, to obtain the electromagnetic signal strength information of the coil, and determine the motion feature of the display module according to the obtained electromagnetic signal strength information, wherein the motion feature includes at least one of the following: the motion direction of the display module, the stretching size of the display module, and the motion speed of the display module.

[0032] In an implementation manner, the transmitting module can be an active transmitting module or a passive transmitting module. The active transmitting module obtains electric energy through a connection circuit. The passive transmitting module obtains electric energy through relative motion in the magnetic field generated by the electromagnetic plate 130. The control loop board controls at least one coil on the electromagnetic plate 130 to be conductive to make the electromagnetic plate 130 generate a magnetic field, so that the passive transmitting module in relative motion obtains electric energy.

[0033] In an implementation manner, the electromagnetic plate 130 is provided with a plurality of coils. The plurality of coils are distributed longitudinally and transversely, and each coil has a corresponding coordinate. The structural diagram of the display module can refer to FIG. 2. Figure 2 As shown in FIG. 2, the display module includes a glass cover plate 210, a flexible screen 220, an electromagnetic plate 231, a control loop board 232, and an electromagnetic shield 240 arranged in sequence. The electromagnetic plate 231 is provided with a plurality of coils, and the plurality of coils are distributed longitudinally and transversely, and each coil has a corresponding coordinate.

[0034] Thus, the electromagnetic signal can be actively transmitted and received by the electromagnetic technology, and the motion feature of the display module can be determined based on the electromagnetic signal, so that the motion feature of the display module can be detected.

[0035] In an implementation manner, the transceiving module 140 is a receiving module, and the receiving module is configured to receive the electromagnetic signal transmitted by the electromagnetic plate 130. The control circuit board is configured to control the coil on the electromagnetic plate 130 to be electrified to make the electromagnetic plate 130 generate a magnetic field, so that the receiving module in relative motion receives the electromagnetic signal transmitted by the electromagnetic plate 130. The electronic device can determine the motion feature of the display module according to the electromagnetic signal strength information of the receiving module, where the motion feature includes at least one of the following: the motion direction of the display module, the expansion size of the display module, and the motion speed of the display module.

[0036] Thus, the electromagnetic signal can be actively transmitted and received by the electromagnetic technology, and the motion feature of the display module can be determined based on the electromagnetic signal, so that the motion feature of the display module can be detected.

[0037] In an implementation manner, in the case where the transceiving module 140 is a receiving module, the number of coils on the electromagnetic plate 130 is one. In this embodiment, the coil is arranged at the first end of the display module, and in the case where the display module moves, the first end is away from or close to the shell.

[0038] In this embodiment, the motion of the display module includes expansion and contraction of the display module. In the process of expansion or contraction of the display module, the coil on the electromagnetic plate is always away from or close to the receiving module. Thus, in the case where the receiving module moves relative to the electromagnetic plate, the motion feature of the display module can be determined according to the strength information of the electromagnetic signal received by the receiving module by controlling the coil on the electromagnetic plate to be electrified to generate a magnetic field.

[0039] In an implementation, in the case that the transceiving module 140 is a transmitting module, the transmitting module is arranged in the pen tip of the stylus. When the stylus is inserted into the fixed position of the electronic device, the pen tip of the stylus serves as the transmitting module. In this way, it is not necessary to additionally arrange a transmitting module in the electronic device, thereby saving cost and device layout space.

[0040] As shown in Figure 3 The embodiment of the present application provides a detection method, which can be applied to the electronic device in the above embodiment, and the method comprises the following steps:

[0041] Step 310: obtaining target electromagnetic signal strength information.

[0042] In the case that the transceiving module is used for transmitting electromagnetic signals to the electromagnetic board, the target electromagnetic signal strength information is the strength information of the electromagnetic signals received by the coils distributed on the electromagnetic board.

[0043] In the case that the transceiving module is used for receiving electromagnetic signals transmitted by the electromagnetic board, the target electromagnetic signal strength information is the strength information of the electromagnetic signals received by the transceiving module.

[0044] Step 320: determining the motion feature of the display module according to the obtained target electromagnetic signal strength information.

[0045] The motion feature comprises at least one of the following: the motion direction of the display module, the stretching size of the display module, and the motion speed of the display module.

[0046] Therefore, the detection method provided by the embodiment of the present application comprises the following steps: obtaining target electromagnetic signal strength information; determining the motion feature of the display module according to the obtained target electromagnetic signal strength information; in the case that the transceiving module is used for transmitting electromagnetic signals to the electromagnetic board, the target electromagnetic signal strength information is the strength information of the electromagnetic signals received by the coils distributed on the electromagnetic board; in the case that the transceiving module is used for receiving electromagnetic signals transmitted by the electromagnetic board, the target electromagnetic signal strength information is the strength information of the electromagnetic signals received by the transceiving module. In this way, the transceiving module in the electronic device is used to transmit electromagnetic signals to the electromagnetic board in the electronic device, to detect the electromagnetic signals received by the coils distributed on the electromagnetic board, or the transceiving module in the electronic device is used to receive electromagnetic signals transmitted by the electromagnetic board, to detect the electromagnetic signals received by the transceiving module, so as to obtain the target electromagnetic signal strength information, and determine the motion feature of the display module according to the target electromagnetic signal strength information, thereby being capable of detecting the motion feature of the display module.

[0047] As shown in Figure 4As shown, the embodiment of the present application provides a detection method. In the embodiment of the present application, the transceiving module is a transmitting module. The target electromagnetic signal strength information is acquired, specifically including:

[0048] Step 410: The electromagnetic signal strength information of each coil is acquired by detecting the magnetic field energy of the coils distributed on the electromagnetic plate.

[0049] After the electromagnetic plate receives the electromagnetic signal transmitted by the transmitting module, the magnetic field energy of the coils distributed on the electromagnetic plate changes, specifically the magnetic flux of the coil at the projection position of the transmitting module changes. At this time, the magnetic field energy of the multiple coils on the electromagnetic plate can be scanned and detected to acquire the electromagnetic signal strength information of each coil.

[0050] The electromagnetic signal strength of the coil is strongly related to the distance from the coil to the transmitting module, for example, Figure 5 As shown, the closer the coil is to the transmitting module, the stronger the electromagnetic signal strength of the coil. Therefore, by acquiring the electromagnetic signal strength information of each coil, the position information of the transmitting module relative to the electromagnetic plate can be determined.

[0051] After acquiring the electromagnetic signal strength information of each coil, the motion characteristics of the display module are determined according to the acquired target electromagnetic signal strength information, specifically including steps 421-422:

[0052] Step 421: The position information of the transmitting module relative to the electromagnetic plate is determined according to the electromagnetic signal strength information of each coil.

[0053] The position information includes at least one of the following: coordinate information, moving direction, and moving speed.

[0054] In one implementation, the coordinates of the transmitting module relative to the electromagnetic plate can be determined according to the electromagnetic signal strength information of each coil, and the moving direction and / or moving speed of the coordinates of the transmitting module relative to the electromagnetic plate can be determined according to the trend of the change of the coordinates of the transmitting module relative to the electromagnetic plate.

[0055] Step 422: The motion characteristics of the display module are determined according to the position information of the transmitting module relative to the electromagnetic plate.

[0056] After obtaining the position information of the transmitting module relative to the electromagnetic plate, the motion characteristics of the display module are converted based on the relative motion relationship.

[0057] In one implementation, before acquiring the electromagnetic signal strength information of each coil, the method further includes:

[0058] The at least one coil of the plurality of coils is controlled to be energized to generate a magnetic field. When the display module is in motion, the magnetic field generated by the transmitting module relative to the electromagnetic plate moves relative to the transmitting module, and the coil inside the transmitting module accumulates electromagnetic energy.

[0059] In the case that the display module is in motion, the power supply to the at least one coil is cut off, and the coil on the electromagnetic plate is controlled to be connected to the target loop, so that the coil on the electromagnetic plate receives the electromagnetic signal transmitted by the transmitting module. For example, in the case that the user inputs a stretching instruction by controlling the key, the power supply to the at least one coil is cut off, and the coil on the electromagnetic plate is controlled to be connected to the target loop, so that the coil on the electromagnetic plate receives the electromagnetic signal transmitted by the transmitting module.

[0060] Therefore, the electromagnetic plate can be used to generate a magnetic field to provide electromagnetic energy for the transmitting module, so that the transmitting module can be a passive transmitting module, and the transmitting module can obtain electrical energy by relative motion in the magnetic field generated by the electromagnetic plate without additional power supply.

[0061] As shown in Figure 6 , the embodiment of the present application provides a detection method.

[0062] In the embodiment of the present application, the target electromagnetic signal strength information is obtained, specifically including steps 510-520:

[0063] Step 510: In the case that the display module is in motion, the coil on the electromagnetic plate is controlled to be energized according to a predetermined rule.

[0064] The predetermined rule includes controlling the current intensity of the coil distributed on the electromagnetic plate to be connected, so that the magnetic field intensity generated by the electromagnetic plate gradually increases, or gradually decreases, or is regularly distributed along the stretching direction of the display module, and the present application does not limit the specific preset rule.

[0065] It can be understood that, in the case that the display module is in a static state, it is not necessary to control the coil on the electromagnetic plate to be energized according to the predetermined rule.

[0066] In addition, since the coil on the electromagnetic plate is controlled to be energized according to the predetermined rule in the embodiment of the present application, the magnetic field intensity and the change trend generated by the electromagnetic plate can be controlled, and therefore the sensitivity of the receiving module is not strictly required. If the sensitivity of the receiving module is low, the overall magnetic field intensity of the electromagnetic plate can be appropriately increased, so that the magnetic field intensity generated by the electromagnetic plate can be adapted to the receiving module.

[0067] Step 520: Obtain the intensity information of the electromagnetic signal received by the receiving module.

[0068] The preset rule is used to control the current intensity of the coil distributed on the electromagnetic plate, so that the magnetic field intensity gradually increases along the extension direction of the display module. For example, when the display module is extended, the electromagnetic signal intensity received by the receiving module in the electronic device is weakened. Since the variation curve of the magnetic field intensity generated by the electromagnetic plate is known, the motion characteristics of the display module can be calculated based on the acquired electromagnetic signal intensity information received by the receiving module.

[0069] After the electromagnetic signal intensity information received by the receiving module is acquired, step 530 is performed: determining the motion characteristics of the display module according to the electromagnetic signal intensity information received by the receiving module.

[0070] The electromagnetic signal intensity information includes intensity, intensity variation trend, and intensity variation speed.

[0071] In an implementation manner, step 530 specifically includes at least one of the following:

[0072] Step 531: determining the extension size of the display module according to the intensity of the electromagnetic signal received by the receiving module.

[0073] Step 532: determining the motion direction of the display module according to the intensity variation trend of the electromagnetic signal received by the receiving module.

[0074] Step 533: determining the motion speed of the display module according to the intensity variation speed of the electromagnetic signal received by the receiving module.

[0075] In addition, the present application also considers that the long-term repeated extension and contraction of the display module will inevitably cause faults, and the extension and contraction may be discontinuous, thereby causing the display of the display module to be disordered and reducing the user experience. Therefore, in an implementation manner, after the motion characteristics of the display module are determined, the method further includes:

[0076] In the case where the motion of the display module is non-uniform motion, display prompt information and / or sending the prompt information to a server, wherein the prompt information indicates that the motion of the display module is non-uniform motion.

[0077] Therefore, whether the display module moves at a uniform speed can be detected in time, and the problem is intercepted and reported to the system before the user realizes that the extension and contraction of the display module have obvious pauses, so as to prompt the user to repair before the mechanical structure is obviously damaged, and to provide the use data of the mechanical structure to the manufacturer, so as to better optimize the manufacturer.

[0078] It should be noted that the detection method provided in the embodiments of the present application can be executed by a detection device or a control module in the detection device for executing the detection method.

[0083] In an implementation manner, the device further includes a control module configured to control at least one coil of the coils to be powered on before the target electromagnetic signal strength information is acquired; and in a case where the display module enters a motion state, cut off power supply of the at least one coil and control the coils on the electromagnetic plate to conduct the target loop, so that the coils on the electromagnetic plate receive electromagnetic signals emitted by the transmitting module.
