[0002] This application relates to the field of terminal technologies, and in particular, to an electronic device, a control method thereof, and an infrared module. Background Art

[0003] Some electronic devices are built-in with infrared functions and can directly control and associate these related devices by using the electronic device as a remote control. Usually, the infrared module of the electronic device is set at the top of the fuselage for easy use. However, since the emission direction of the infrared module is fixed and the top space of the electronic device is limited, it is usually necessary to open a hole in the middle frame and conduct the infrared rays emitted by the infrared emitter through a light guide column. The size of the hole is limited by the body space of the electronic device, resulting in a limited infrared emission field of view (FOV), which affects the user's use of the infrared function. Summary of the Invention

[0004] Embodiments of this application provide an electronic device, a control method thereof, and an infrared module to improve the problem that when the infrared module is configured at the top of the electronic device body, the emission direction of the infrared module is fixed, the field of view is small, and the normal use is affected.

[0005] To achieve the above object, the solutions adopted in the embodiments of this application are as follows:

[0006] In a first aspect, embodiments of this application provide an electronic device, which includes a middle frame, a housing, a processor, and an infrared module. The housing covers the middle frame, the processor and the infrared module are disposed in the accommodation space formed by the housing and the middle frame. The housing includes a transparent cover plate, and the infrared module is disposed under the transparent cover plate. In this way, problems such as limited FOV caused by opening holes in the middle frame and using light guide columns can be avoided by setting the infrared module under the transparent cover plate without the need to set a light guide column, and the FOV of infrared emission is larger. The processor is configured to adjust the emission direction of the infrared rays emitted by the infrared module relative to the transparent cover plate in response to the inclination of the electronic device in the pitch direction. In this way, the influence of the inclination angle of the electronic device on the infrared emission distance can also be overcome. For example, when the electronic device pitches at a certain angle, the emission direction of the infrared rays can be adjusted downward or moved downward to overcome problems such as limited emission distance caused by the electronic device tilting upward or downward.

[0007] In a possible implementation, the infrared module includes an adjusting device, a first bracket, and an infrared emitter.

By setting the first adjusting device and the second adjusting device, both the first adjusting device and the second adjusting device can operate independently or together, which can increase the reliability of the infrared module of the electronic device.

[0013] In a possible implementation, the second adjusting device includes a second coil and a second magnetic member.

[0049] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

[0050] Hereinafter, the terms "first", "second", etc. are only used for convenience of description and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of this application, unless otherwise specified, the meaning of "a plurality" is two or more. For example, a plurality of processing units means two or more processing units.

[0051] In addition, in the embodiments of this application, the "upper", "lower", "left", and "right" are not limited to being defined by the orientation of the components in the relative drawings. It should be understood that these directional terms may be relative concepts, which are used for relative description and clarification and may change accordingly with the change of the orientation of the components in the drawings. In the drawings, for clarity, the thickness of the layers and regions is exaggerated, and the dimensional proportional relationship between the various parts in the drawings does not reflect the actual dimensional proportional relationship.

[0052] In the embodiments of this application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" may be a fixed connection, a detachable connection, or integrated; it may be directly connected or indirectly connected through an intermediate medium. In addition, the term "electrical connection" may be a direct electrical connection or an indirect electrical connection through an intermediate medium.

[0053] In the embodiments of this application, the term "module" is usually a functional structure divided logically, and this "module" may be implemented by pure hardware or a combination of software and hardware. In the embodiments of this application, "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, B exists alone, and both A and B exist simultaneously.

[0054] In the embodiments of this application, words such as "exemplary" or "for example" are used to represent examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Exactly speaking, using words such as "exemplary" or "for example" is intended to present relevant concepts in a specific way.

[0055] Infrared, also known as infrared ray, is an electromagnetic wave in the infrared band with a wavelength range of 0.76 - 1000 micrometers, which is between visible light and microwaves. Infrared ray is an electromagnetic wave with wide applications and has extensive applications in the fields of security monitoring, healthcare, wireless control, etc.

[0056] For example, an electronic device such as a smartphone is provided with an infrared function, which can be used to sense the call status of the user. For example, when the user picks up the phone to answer a call, the infrared function detects that the phone is close to the ear, and the screen of the phone can be turned off to avoid accidental touch; or the infrared can also be used to sense the external environment. Usually, an infrared sensor is set at the top or bottom of the phone to monitor the ambient brightness, so that the brightness, color, etc. of the phone screen can be adjusted according to the ambient brightness.

[0057] In addition to being used for monitoring, the infrared can also be used for data transmission, or controlling associated devices, etc. For example, devices such as TVs and air conditioners that support infrared control. If some mobile phones are built-in with infrared functions, then these devices can be directly controlled and associated through the mobile phone, and the mobile phone can be used as a remote control.

[0058] Like a remote control, usually the infrared module of an electronic device such as a mobile phone is set at the top of the body as Figure 1A shown, which is convenient for use. However, due to the limited space at the top of the electronic device such as a mobile phone, it is usually necessary to open a hole in the middle frame. Refer to Figure 1B , and the infrared rays emitted by the infrared emitter are conducted out through a light guide column. The size of the hole is limited by the body space of the electronic device. Usually, the size of the opening is about 1.6 mm, which will result in a limited field of view (FOV) of the infrared emission, affecting the user's use of the infrared function.

[0059] Since the infrared rays do not have the ability to pass through obstacles to control the controlled object like radio remote control, when using the infrared rays to control the controlled object, usually the infrared emitter needs to be aligned with the controlled object. However, when controlling a distant object, a smaller FOV will result in misalignment. As Figure 2 shown, when the user uses the electronic device, if the infrared emitter cannot be aligned with the controlled object due to the change of the holding angle, the controlled object may not be able to be controlled, affecting the user experience.

[0060] Here, the limited FOV of the infrared rays emitted by the infrared emitter is due to the limitation of the size of the opening in the middle frame and the light guide column, etc. The infrared rays emitted by the infrared emitter can only be conducted through the light guide column set in the opening of the middle frame. Since the opening in the middle frame is small, the width (diameter) of the light guide column is limited, resulting in a limited FOV of the infrared rays emitted by the infrared emitter.

[0061] Therefore, the embodiment of the present application provides a solution to improve the FOV of the infrared rays, which is applied to electronic devices such as mobile phones and tablet computers. Taking the electronic device as a mobile phone as an example below, Figure 3 shows a schematic structural diagram of an electronic device provided by the embodiment of the present application.

The FOV for guiding infrared rays is small. In the solution provided by the embodiments of the present application, the infrared module 300 is set under the transparent cover plate 298, without the need for opening holes, reducing occlusion. In addition, the infrared rays can be emitted outward through the transparent cover plate 298, and power loss caused by the light guide column conducting infrared rays can also be avoided.

[0089] Exemplarily, in combination with Figure 5 , the housing 297 can be covered on the middle frame 296. The housing 297 includes a transparent cover plate 298. The camera module 193 and the infrared module 300 of the electronic device are set below the transparent cover plate 298, or are set in the space formed between the transparent cover plate 298 and the middle frame 296.

[0090] The infrared module 300 is set under the transparent cover plate 298, so that the infrared light emitted by the infrared module 300 can be diverged outward through the transparent cover plate 298. Since the area of the transparent cover plate 298 is much larger than the areas of the infrared module 300 and the camera module 193, and the transparent cover plate 298 can transmit light, setting the infrared module 300 under the transparent cover plate 298 will not cause occlusion, avoiding the problem of the FOV limitation of the infrared light emitted by the infrared module 300 due to the opening in the middle frame and the light guide column in the foregoing solution, and preventing the infrared function of the electronic device from affecting the user experience due to the limited FOV of the infrared rays.

[0091] In a possible implementation manner, the transparent cover plate 298 includes a first region 2981 and a second region 2982. The camera module 193 is aligned with the first region 2981, and the infrared module 300 is aligned with the second region 2982. An infrared ink layer can be coated on the second region 2982, and the infrared ink layer can only pass through infrared rays and filter out light of other wavelengths.

[0092] The above-mentioned transparent cover plate 298 can be a transparent decorative cover plate for the camera module 193, also known as a Decorate Film (DECO for short). The DECO can be made of organic materials or tempered glass and other materials. Setting the infrared module 300 under the DECO of the camera module 193 can save the internal space of the electronic device. In order to avoid the mutual influence of light between the infrared module 300 and the camera module 193, a foam can be set between the infrared module 300 and the second region 2982 to prevent infrared rays from leaking.

[0093] Although setting the infrared module 300 under the transparent cover plate 298 can increase the FOV of the infrared rays of the electronic device, however, due to the user's usage habits, refer to Figure 6, when a user uses an electronic device, the body of the electronic device usually does not present a horizontal or vertical state, but has a certain inclination angle to facilitate the user to view the content displayed on the display screen 294.

[0094] Combined with Figure 7 , if the electronic device is placed in an XYZ inertial coordinate system, where the Z-axis is perpendicular to the display screen of the electronic device and points upward, the X-axis is parallel to the axis of the body of the electronic device and points forward in the body reference plane of the electronic device, and the Y-axis is perpendicular to the X-axis and points to the right of the electronic device in the body reference plane of the electronic device. The angle of rotation of the electronic device around the X-axis is called the roll angle, the angle of rotation of the electronic device around the Y-axis is called the pitch angle, and the angle of rotation of the electronic device around the Z-axis is called the yaw angle.

[0095] When the infrared module 300 of the electronic device is arranged under the transparent cover plate on the housing of the electronic device, the center line of the FOV of the infrared ray is perpendicular to the plane where the housing is located. When the electronic device has a certain inclination angle, it has an impact on the reach range of the infrared ray emitted by the infrared module of the electronic device, or rather, it has an impact on controlling a controlled object at a long distance.

[0096] For example, referring to Figure 8 and Figure 9 , when the plane where the housing 297 of the electronic device is perpendicular to the horizontal plane and the emission direction of the infrared ray ( Figure 8 the A0 direction shown) is emitted in the horizontal direction, the distance that can be reached in the horizontal direction is the farthest, and a controlled object at a relatively long distance can be controlled. When the electronic device has a certain inclination angle, for example, when the pitch angle is α, since the housing 297 of the electronic device is inclined towards the horizontal plane, and the emission direction of the infrared ray ( Figure 9 the A1 direction shown) is perpendicular to the plane where the housing 297 is located, this will cause the central direction of the infrared ray emitted by the infrared module 300 to also shift downward, and the distance that the infrared ray can reach in the horizontal direction is shortened, which may cause the inability to align a controlled object at a relatively long distance.

[0097] Combined with Figure 8 and Figure 9It can be known that if you want to make the emission distance of infrared rays the farthest in the horizontal direction, the infrared rays need to be emitted horizontally. However, in this case, the electronic device needs to be kept perpendicular to the horizontal plane, which does not conform to the user's usage habits. When the infrared module 300 is arranged under the transparent cover plate 298 of the housing 297, when using the infrared function of the terminal, the distance that the infrared rays can reach in the horizontal direction is greatly affected by the pitch angle of the electronic device. Due to the user's usage habits, when using the electronic device, the electronic device usually presents a certain pitch angle, and this pitch angle will cause the distance that the infrared rays can reach in the horizontal direction to be shortened. Therefore, when using the infrared ray function of the electronic device, the user may need to adjust the posture of the electronic device so that the distance that the infrared rays can reach in the horizontal direction is farther, and a better control range can be obtained when using the infrared rays to control the controlled object.

[0098] For this reason, the embodiments of the present application provide a solution that can adjust the emission angle of the infrared rays according to the pitch angle of the electronic device. For example, as Figure 10 shown, when the electronic device presents a certain pitch angle, resulting in the plane of the housing 297 tilting downward obliquely, the emission direction of the infrared rays also tilts downward (for example, Figure 10 the A1 direction in ), the electronic device provided by the embodiments of the present application can adjust the emission angle of the infrared rays so that the emission angle of the infrared rays can overcome the influence of the pitch angle of the electronic device and still maintain the state of being emitted along the horizontal direction or close to the horizontal direction (such as Figure 10 the A2 direction in ), so that the infrared rays can control the controlled object at a farther distance.

[0099] Exemplarily, the embodiments of the present application provide an infrared module 300 that can adjust the emission angle of the infrared rays. Refer to Figure 11 , Figure 11 shows a schematic structural diagram of the infrared module 300 provided by the embodiments of the present application. The infrared module 300 includes a first bracket 310, a second bracket 320, an infrared emitter 330, and an adjusting device.

[0100] Among them, the second bracket 320 includes a base 321 and a support column 322 connected to the base 321. One end of the support column 322 away from the base 321 is connected to the first bracket 310. The infrared emitter 330 is installed on the first bracket 310, and the infrared emitter 330 can emit infrared rays toward the side away from the second bracket 320. Among them, the adjusting device includes a first adjusting device 341. The first adjusting device 341 is arranged on the base 321, and the first adjusting device 341 is connected to the first bracket 310. The first adjusting device 341 is used to drive the first bracket 310 to deflect or rotate in the first direction or the second direction, so as to drive the outgoing direction of the infrared rays emitted by the infrared emitter 330 installed on the first bracket 310 to deflect or rotate in the first direction or the second direction. Exemplarily, the first direction here can refer to the counterclockwise direction around the Y axis in the aforementioned XYZ coordinate system, and the second direction can refer to the clockwise direction around the Y axis in the aforementioned XYZ coordinate system. When the electronic device rotates around the Y axis to generate a pitch angle, the emission direction of the infrared rays emitted by the infrared emitter 330 of the infrared module 300 can also rotate around the Y axis by a certain angle, so as to avoid the influence of the posture of the electronic device on the infrared function.

[0101] For example, refer to Figure 12 When the electronic device rotates an angle β clockwise (i.e., in the first direction) around the Y axis from the vertical state, that is, the state perpendicular to the horizontal plane (pitch angle is 90°), the pitch angle at this time is α, and α + β = 90°. If the emission direction of the infrared rays is not adjusted, then the outgoing direction of the infrared rays is obliquely downward at an angle of β with the horizontal plane. This will shorten the distance that the infrared rays can reach. The electronic device provided in the embodiment of the present application can adjust the outgoing direction of the infrared rays. For example, rotate the outgoing direction of the infrared rays counterclockwise (i.e., in the second direction) around the Y axis by an angle β. In this way, the outgoing direction of the infrared rays can be restored to be emitted along the horizontal direction. The infrared rays emitted along the horizontal direction can reach a farther distance than the infrared rays emitted obliquely downward, so that the range within which the electronic device can effectively control the controlled device using infrared rays is increased.

[0102] Exemplarily, refer to Figure 13 , when the first adjusting device 341 applies a force to the first bracket 310 in the direction away from the second bracket 320, the first bracket 310 deflects or rotates in the first direction (i.e., the clockwise direction around the Y axis). In this case, the outgoing direction of the infrared rays emitted by the infrared emitter 330 also deflects or rotates in the first direction along with the first bracket 310.

[0103] Exemplarily, refer to Figure 14, when the first adjusting device 341 applies a force on the first bracket 310 towards the second bracket 320, the first bracket 310 deflects or rotates in the second direction (i.e., the counterclockwise direction around the Y axis). In this case, the emission direction of the infrared rays emitted by the infrared emitter 330 also deflects or rotates in the second direction along with the first bracket 310.

[0104] In a possible implementation, the first bracket 310 is movably connected to the support column 322, so that the first adjusting device 341 can drive the first bracket 310 to deflect in the first direction or the second direction.

[0105] Alternatively, the first bracket 310 can be rotatably connected to the support column 322, so that the first adjusting device 341 can drive the first bracket 310 to rotate in the first direction or the second direction. Exemplarily, the first bracket 310 can be connected to the support column 322 by a rotating shaft connection, a ball head connection, etc.

[0106] Of course, the first bracket 310 can also be fixedly connected to the support column 322. In this case, the support column 322 can be selected to be made of an elastic material, so that when the first adjusting device 341 applies a force on the first bracket 310, the support column 322 can undergo elastic deformation, causing the first bracket 310 to deflect or rotate in the first direction or the second direction.

[0107] Exemplarily, in a possible implementation, refer to Figure 15 , the adjusting device can further include a second adjusting device 342. The second adjusting device 342 and the first adjusting device 341 are distributed on both sides of the support column 322. The second adjusting device 342 is disposed on the base 321 of the second bracket 320 and is connected to the first bracket 310.

[0108] The structure and principle of the second adjusting device 342 are the same as those of the first adjusting device 341. The second adjusting device 342 can also apply a force on the first bracket 310 in the direction away from the second bracket 320 or in the direction towards the second bracket 320, driving the first bracket 310 to deflect or rotate in the second direction or the first direction.

[0109] In a possible implementation manner, both the first adjusting device 341 and the second adjusting device 342 include two working states, that is, applying a force on the first bracket 310 in the direction close to the second bracket 320 or applying a force on the first bracket 310 in the direction away from the second bracket 320.

[0110] For example, when the first adjusting device 341 applies a force to the first bracket 310 in the direction approaching the second bracket 320, the first bracket 310 deflects or rotates in the second direction; when the first adjusting device 341 applies a force to the first bracket 310 in the direction away from the second bracket 320, the first bracket 310 deflects or rotates in the first direction.

[0111] Since the second adjusting device 342 and the first adjusting device 341 are distributed on both sides of the support column 322, the forces in the same direction applied by them to the first bracket 310 will produce opposite effects.

[0112] For example, when the second adjusting device 342 applies a force to the first bracket 310 in the direction approaching the second bracket 320, the first bracket 310 deflects or rotates in the first direction; when the second adjusting device 342 applies a force to the first bracket 310 in the direction away from the second bracket 320, the first bracket 310 deflects or rotates in the second direction.

[0113] In such a case, when the first bracket 310 deflects or rotates in the first direction or the second direction, it is simultaneously driven by the first adjusting device 341 and the second adjusting device 342, and deflects or rotates under the combined action of the first adjusting device 341 and the second adjusting device 342.

[0114] In the above example, the first adjusting device 341 can apply a force to the first bracket 310 towards the second bracket 320 or away from the second bracket 320, and the second adjusting device 342 can apply a force to the first bracket 310 away from the second bracket 320 or towards the second bracket 320, which means that the first adjusting device 341 and the second adjusting device 342 can independently drive the first bracket 310 to rotate or deflect in the first direction or the second direction, thereby driving the emission direction of the infrared emitter 330 to deflect or rotate. When one of the first adjusting device 341 and the second adjusting device 342 fails, the other can drive the first bracket 310 to rotate or deflect in the first direction or the second direction, thereby driving the emission angle of the infrared emitter 330 to deflect or rotate.

[0115] Alternatively, in some other possible examples, the first adjusting device 341 and the second adjusting device 342 can respectively apply a force in only one direction to the first bracket 310. For example, the first adjusting device 341 applies a force to the first bracket 310 in the direction towards the second bracket 320, and the second adjusting device 342 applies a force to the first bracket 310 in the direction away from the second bracket 320; or the first adjusting device 341 applies a force to the first bracket 310 in the direction away from the second bracket 320, and the second adjusting device 342 applies a force to the first bracket 310 in the direction towards the second bracket 320. In this case, the first adjusting device 341 and the second adjusting device 342 can respectively only drive the first bracket 310 to rotate in the first direction or the second direction. It is necessary for the first adjusting device 341 and the second adjusting device 342 to act together to enable the first bracket 310 to have the ability to rotate or shift in different directions. The first adjusting device 341 and the second adjusting device 342 are used to drive the first bracket 310 to shift or rotate, so as to drive the infrared emitter 330 mounted on the first bracket 310 to shift or rotate the emission direction of the infrared ray.

[0116] Exemplarily, in a possible implementation manner, the first adjusting device 341 and the second adjusting device 342 can be telescopic rods. The telescopic rod can include a fixed part and a movable part. The fixed part is mounted on the base 321 of the second bracket 320. One end of the movable part is connected to the fixed part, and the other end of the movable part is connected to the first bracket 310. The movable part can be telescopic. When the movable part extends, a force in the direction away from the second bracket 320 is applied to the first bracket 310. When the movable part retracts, a force in the direction towards the second bracket 320 is applied to the first bracket 310.

[0117] Alternatively, in another possible implementation manner, the first adjusting device 341 and the second adjusting device 342 can be voice coil motors or drive motors with the same function. The voice coil motor or the drive motor is connected to the first bracket 310 through a transmission mechanism. When the voice coil motor or the drive motor rotates forward, a force in the direction away from the second bracket 320 is applied to the first bracket 310 through the transmission mechanism. When the voice coil motor or the drive motor rotates in reverse, a force in the direction towards the second bracket 320 is applied to the first bracket 310 through the drive mechanism, so as to drive the first bracket 310 to shift or rotate in the first direction or the second direction, and drive the emission direction of the infrared emitter 330 to rotate in the first direction or the second direction.

[0118] However, due to the limited space of the electronic device, the telescopic rod, the voice coil motor, etc. as the first adjusting device 341 and the second adjusting device 342 occupy a large space and have a high cost. Therefore, the embodiment of the present application provides another implementation manner, which can reduce the occupied space of the first adjusting device 341 and the second adjusting device 342 and can also reduce the cost.

[0119] Exemplarily, referring to Figure 16 , taking the first adjusting device 341 as an example, the first adjusting device 341 includes a first coil 3411 and a first magnetic member 3412. When there is an electric current passing through the first coil 3411, a magnetic field will be generated, thereby attracting the first magnetic member 3412. Among them, one of the first coil 3411 and the first magnetic member 3412 can be disposed on the second bracket 320, and the other can be disposed on the first bracket 310. For example, the first coil 3411 is disposed on the base 321 of the second bracket 320, and the first magnetic member 3412 can be installed at a corresponding position on the first bracket 310, so that the first coil 3411 and the first magnetic member 3412 can be disposed opposite to each other. When the first coil 3411 is powered on, it can attract the first magnetic member 3412. The first magnetic member 3412 is installed on the first bracket 310. Therefore, when the first magnetic member 3412 is attracted by the first coil 3411, the first magnetic member 3412 can apply a force toward the second bracket 320 to the first bracket 310, driving the first bracket 310 to deflect or rotate in the first direction, and driving the emission direction of the infrared emitter 330 to also rotate in the first direction.

[0120] Or, the first coil 3411 is disposed on the base 321 of the second bracket 320, and the first magnetic member 3412 is installed at a corresponding position on the first bracket 310, so that the first coil 3411 and the first magnetic member 3412 can be disposed opposite to each other, so that when the first coil 3411 is powered on, it can attract the first magnetic member 3412. Since the first magnetic member 3412 is fixedly installed on the second bracket 320, the reaction force of the first magnetic member 3412 on the first coil 3411 can drive the first bracket 310 to deflect or rotate in the first direction, driving the emission direction of the infrared emitter 330 to also rotate in the first direction.

[0121] It can be seen from the above that the coil can be disposed on the second bracket 320, and at the same time, the magnetic member is disposed on the first bracket 310, or the coil can be disposed on the first bracket 310, and at the same time, the magnetic member is disposed on the second bracket 320. For the convenience of description, in the subsequent examples of the present application, the coil is disposed on the second bracket 320 and the magnetic member is disposed on the first bracket 310 as an example.

[0122] Continuing with the first adjusting device 341 as an example, the first magnetic member 3412 can be an iron sheet, fixedly arranged on one side of the first bracket 310 facing the second bracket 320, or the first magnetic member 3412 can also be a sheet-like structure made of ferromagnetic materials such as iron, steel, nickel, and cobalt.

[0123] The second adjusting device 342 has the same structure as the first adjusting device 341. The second adjusting device 342 includes a second coil 3421 and a second magnetic member 3422. The second coil 3421 is arranged on the base 321 of the second bracket 320, and the second magnetic member 3422 is arranged on the first bracket 310. When there is a current passing through the second coil 3421, a magnetic field will be generated to attract the second magnetic member 3422, driving the first bracket 310 to rotate in the second direction, thereby driving the emission direction of the infrared emitter 330 to shift or rotate in the second direction.

[0124] Exemplarily, the reason why the first adjusting device 341 and / or the second adjusting device 342 drive the first bracket 310 to shift or rotate is due to the force between the energized coil and the magnetic member. According to the right-hand screw rule, the greater the current passing through the coil and the more turns of the coil, the stronger the formed magnetic field. Therefore, the first adjusting device 341 and / or the second adjusting device 342 can adjust the magnitude of the force applied to the first bracket 310 by adjusting the magnitude of the coil current.

[0125] The force F applied by the first adjusting device 341 and the second adjusting device 342 to the first bracket 310 satisfies: F = BIL, where B is the magnetic field strength. After the number of turns of the windings of the first coil 3411 and the second coil 3421 is fixed, B is determined by the current intensity flowing through the coil. I is the intensity of the induced current on the magnetic member, and L is the length of the conductor in the magnetic field. Taking the first coil 3411 as an example, the greater the current of the first coil 3411, the greater the generated magnetic field strength, the greater the induced current I generated on the magnetic member, and thus the greater the electromagnetic force F and the greater the force attracting the magnetic member.

[0126] In some possible implementation manners, an iron core can also be inserted into the first coil 3411 and the second coil 3421. After adding the iron core, the magnetic field strength generated when the first coil 3411 and the second coil 3421 are energized can be enhanced.

[0127] In addition, referring to Figure 17 , according to the right-hand screw rule, the direction of the magnetic field generated by the energized coil is related to the direction of the current. If the current passing through the coil is reversed, then the direction of the generated magnetic field will also change in the opposite direction.

[0128] Therefore, in combination with the foregoing examples, both the first adjusting device 341 and the second adjusting device 342 can apply a force to the first bracket 310 in the direction of approaching the second bracket 320 or in the direction of moving away from the second bracket 320. In this case, it can be achieved by changing the direction of the current flowing through the first coil 3411 and the second coil 3421 and adjusting the magnitude of the current.

[0129] In a possible implementation manner, the first adjusting device 341 can only apply a force to the first bracket 310 in the direction of approaching the second bracket 320, and the second adjusting device 342 can only apply a force to the first bracket 310 in the direction of moving away from the second bracket 320. Or, the first adjusting device 341 can only apply a force to the first bracket 310 in the direction of moving away from the second bracket 320, and the second adjusting device 342 can only apply a force to the first bracket 310 in the direction of approaching the second bracket 320. In this case, it can be achieved by changing the magnitude of the current flowing through the first coil 3411 and the second coil 3421. For example, if the magnitude of the current flowing through the first coil 3411 is relatively large, and the magnitude of the current flowing through the second coil 3421 is relatively small or zero, then the force applied by the first adjusting device 341 is relatively large, which is reflected in that the first bracket 310 deflects or rotates in the first direction under the force applied by the first adjusting device 341; conversely, if the magnitude of the current flowing through the second coil 3421 is relatively large, and the magnitude of the current flowing through the first coil 3411 is relatively small or zero, then the force applied by the second adjusting device 342 is relatively large, which is reflected in that the first bracket 310 deflects or rotates in the second direction under the force applied by the second adjusting device 342.

[0130] Based on the infrared module 300 provided in the above examples, when a user uses an electronic device, the direction in which the infrared module 300 emits infrared rays can be changed, so that the influence of the posture of the electronic device on the effective range of the infrared function of the electronic device can be reduced.

[0131] Exemplarily, an infrared driving circuit can be provided on the main board of the electronic device. The infrared driving circuit includes a first output terminal P1 and a second output terminal P2, where the first output terminal P1 is electrically connected to the first coil 3411, and the second output terminal P2 is electrically connected to the second coil 3421.

[0132] The processor 210 of the electronic device can control the infrared driving circuit to adjust the direction and magnitude of the current output to the first coil 3411 and the second coil 3421, thereby changing the emission angle of the infrared rays.

[0133] Combined with the foregoing examples, the impact of the attitude change of the electronic device on the infrared function of the user clock is mainly reflected in that the pitch angle of the electronic device causes the arrival distance of the infrared ray to shorten. Especially when the pitch angle of the electronic device is positive and the back cover of the electronic device is inclined towards the ground, the emission angle of the infrared ray also faces the ground, which will cause the infrared ray to be unable to reach a relatively far controlled object.

[0134] In the solution provided by the embodiment of the present application, the infrared module 300 can be disposed under the transparent cover plate 298 of the cover plate of the electronic device. The emission angle of the infrared emitter 330 can be deflected under the drive of the first adjusting device 341 and the second adjusting device 342. Since the infrared ray module is mainly affected by the pitch angle of the electronic device, the adjustment of the infrared emitter 330 by the first adjusting device 341 and the second adjusting device 342 is mainly to offset or reduce the influence of the pitch angle of the electronic device on the emission angle of the infrared emitter 330.

[0135] Exemplarily, in a possible implementation manner, refer to Figure 18A , the connection line of the first adjusting device 341 and the second adjusting device 342 is parallel to the body axis of the electronic device, or parallel to the X axis mentioned in the foregoing example. Thus, when the first adjusting device 341 and the second adjusting device 342 apply a force to the first bracket 310, the first bracket 310 can rotate or shift in the first direction (clockwise around the Y axis), or the first bracket 310 can rotate or shift in the second direction (counterclockwise around the Y axis), driving the infrared emitter 330 to rotate, so that the emission direction of the infrared ray can also rotate or shift along the second direction or the first direction, keeping the emission direction of the infrared ray along the horizontal direction or close to the horizontal direction, and being able to offset or reduce the influence of the pitch angle of the electronic device on the emission direction and arrival distance of the infrared emitter 330.

[0136] In a possible implementation manner, the adjusting device further includes an infrared driving circuit 343. The processor 210 can control the infrared driving circuit 343 to adjust the magnitude or direction of the current of the first coil 3411 and the second coil 3421 according to the user's instruction, so as to drive the emission direction of the infrared ray emitted by the infrared module 300 to shift or rotate.

[0137] For example, the electronic device includes a touch screen. The processor 210 can respond to the touch operation of the user on the touch screen, control the infrared driving circuit 343 to adjust the current direction, magnitude, etc. output to the first coil 3411 and the second coil 3421, so as to drive the emission angle of the infrared ray emitted by the infrared module 300 to shift or rotate.

[0138] Alternatively, the electronic device includes physical buttons, knobs, etc. The processor 210 can respond to the user's operations on the physical buttons, knobs, etc., and control the infrared drive circuit 343 to adjust the current direction, magnitude, etc. output to the first coil 3411 and the second coil 3421, so as to drive the emission angle of the infrared rays emitted by the infrared module 300 to shift or rotate.

[0139] Alternatively, the electronic device includes a voice control module. The processor 210 can respond to the voice control instructions issued by the user, and control the infrared drive circuit 343 to adjust the current direction, magnitude, etc. output to the first coil 3411 and the second coil 3421, so as to drive the emission angle of the infrared rays emitted by the infrared module 300 to shift or rotate.

[0140] Exemplarily, the electronic device provided in the embodiment of the present application arranges the infrared module 300 under the transparent cover plate. The infrared module 300 is aligned with the second area of the transparent cover plate to expand the FOV of the infrared emission of the infrared module 300. Since the emission direction of the infrared rays emitted by the infrared module 300 can move in the first direction and the second direction, it can be understood that, referring to Figure 18B , the size of the second area 2982 of the transparent cover plate 298 should ensure that when the emission direction of the infrared rays emitted by the infrared module 300 reaches the extreme value range of the first direction and the second direction, it will still not be blocked.

[0141] Although the above examples can adjust the emission direction of the infrared rays emitted by the infrared module 300 and can overcome the influence of the attitude of the electronic device on the arrival distance and effective range of the infrared rays, for the user, the process of using the infrared ray function by the user is more complicated. The user issues instructions to adjust the emission direction of the infrared rays, which increases the user's usage difficulty on the one hand. On the other hand, there may still be a situation where the controlled object cannot be aligned after multiple adjustments, that is, there are situations such as incorrect adjustment direction or insufficient adjustment, which affects the user's usage experience.

[0142] Therefore, the electronic device provided in the embodiment of the present application can automatically adjust the emission direction of the infrared rays of the infrared module 300 according to the pitch angle of the electronic device. Exemplarily, the sensor 280 of the electronic device includes a variety of sensors such as a gyroscope, a gravity sensor, and an acceleration sensor, which can be used to detect the attitude data of the electronic device, such as attitude data such as the tilt angle. The processor 210 can determine the pitch angle of the electronic device according to the data detected by the sensor 280, determine the angle that the emission direction of the infrared rays emitted by the infrared module 300 needs to be adjusted according to the pitch angle of the electronic device, and control the infrared drive circuit 343 to adjust the current magnitude output to the first coil 3411 and the second coil 3421, so as to adjust the emission direction of the infrared rays.

[0143] Exemplarily, referring to Figure 19 , Figure 19The figure shows a schematic diagram of the control system of the infrared module 300 provided by the embodiments of the present application, including a processor 210, an infrared driving circuit 343, a first coil 3411, a second coil 3421, and a sensor 280.

[0144] Among them, the sensor 280 is connected to the processor 210. The sensor 280 may include a gyroscope, a gravity sensor, an acceleration sensor, etc. The attitude data detected by the sensor 280 is sent to the processor 210, and the processor 210 can determine the pitch angle of the electronic device according to the attitude data detected by the sensor.

[0145] The processor 210 is connected to the infrared driving circuit 343. The infrared driving circuit 343 includes a first output terminal P1 and a second output terminal P2. The first output terminal P1 is connected to the first coil 3411, and the second output terminal P2 is connected to the second coil 3421.

[0146] The processor 210 sends a control signal to the infrared driving circuit 343 according to the pitch angle of the electronic device to control the infrared driving circuit 343 to adjust the signal magnitudes output from the first output terminal P1 and the second output terminal P2, and further control the emission angle of the infrared rays emitted by the infrared module 300.

[0147] Exemplarily, refer to Figure 20 , Figure 20 The figure shows a schematic flowchart of the control method of the infrared module provided by the embodiments of the present application, including:

[0148] S510: Obtain an instruction to start the infrared.

[0149] S520: Detect the tilt of the electronic device in the pitch direction.

[0150] When the user enables the infrared function of the electronic device, detect the tilt of the electronic device. Exemplarily, the sensors set on the electronic device can be used to detect the tilt state of the electronic device.

[0151] S530: In response to the tilt of the electronic device in the pitch direction, adjust the emission direction of the infrared rays emitted by the infrared module relative to the transparent cover plate.

[0152] Exemplarily, when the infrared rays emitted by the infrared module are not adjusted with respect to the emission direction of the transparent cover plate, the emission direction of the infrared rays is perpendicular to the transparent cover plate and emitted outward. When the electronic device is tilted, the emission direction of the infrared rays will also change with the tilt of the electronic device. For example, when the electronic device is tilted downward, the emission direction of the infrared rays will also tilt downward; when the electronic device is tilted upward, the emission direction of the infrared rays will also tilt upward. Both tilting upward and downward will cause the reachable distance of the infrared rays to become shorter, affecting the control range of the infrared rays. The solution provided in the embodiments of the present application adjusts the emission direction of the infrared rays emitted by the infrared module with respect to the transparent cover plate in response to the tilt of the electronic device. For example, when the electronic device is tilted downward, the emission direction of the infrared rays with respect to the transparent cover plate is adjusted to move upward, so as to ensure that the infrared rays can be emitted along the horizontal direction as much as possible, and the control range is larger.

[0153] Exemplarily, when the attitude of the electronic device changes, for example, when a certain pitch angle is presented, the emission direction of the infrared module also changes. For example, it changes from being emitted along the horizontal direction to being emitted along an obliquely upward direction or an obliquely downward direction, which will cause the reachable distance of the infrared rays to shorten and the effective control range to shrink. To overcome the influence of the pitch angle of the electronic device on the emission direction of the infrared module, it is necessary to adjust the emission direction of the infrared module so that the infrared rays are emitted along the horizontal direction as much as possible or close to the horizontal direction.

[0154] Exemplarily, in combination with Figure 12 , when the pitch angle of the electronic device is α, α < 90°, before the emission direction is adjusted (as shown by the direction A1 in the figure), the angle between the emission direction of the infrared module and the horizontal plane is -β (positive above the horizontal plane and negative below the horizontal plane), where α + β = 90°. Therefore, it is necessary to rotate the emission direction of the infrared module counterclockwise along the Y-axis, that is, the second direction mentioned in the previous example, by an angle β.

[0155] Exemplarily, when the pitch angle of the electronic device is α, α = 90°, the housing plane of the electronic device is perpendicular to the horizontal plane, and the emission direction of the infrared rays emitted by the infrared module is along the horizontal direction. Therefore, there is no need to adjust the emission direction.

[0156] Exemplarily, in combination with Figure 21 , when the pitch angle of the electronic device is α, 180° > α > 90°, before the emission direction is adjusted (as shown by the direction A1 in the figure), the angle between the emission direction of the infrared module and the horizontal plane is β (positive above the horizontal plane and negative below the horizontal plane), where α - β = 90°. Therefore, it is necessary to rotate the emission direction of the infrared module clockwise along the Y-axis, that is, the first direction mentioned in the previous example, by an angle β.

[0157] Among them, a pitch angle of 0 to 90° can correspond to the posture of the user standing or sitting and using the electronic device, and a pitch angle of 90° to 180° can correspond to the posture of the user lying down and using the electronic device. In the case where the pitch angle is less than 0 degrees or greater than 180°, it can be adjusted correspondingly according to the solutions introduced in the foregoing examples.

[0158] Exemplarily, the processor can respond to the tilt of the electronic device in the pitch direction and control the infrared drive circuit to adjust the magnitude and / or direction of the current in the coil, so as to adjust the emission direction of the infrared rays of the infrared module. After determining the angle adjustment amount, the processor controls the infrared drive circuit to adjust the magnitude and / or direction of the current in the first coil and the second coil, so as to adjust the emission direction of the infrared module by the foregoing angle adjustment amount.

[0159] After adjusting the emission direction of the infrared module by the foregoing angle adjustment amount, the emission direction of the infrared module reaches the target position, and the infrared function is started, and the infrared rays are emitted along the horizontal direction or close to the horizontal direction, so that a longer control distance can be obtained.

[0160] Exemplarily, since the pitch angle of the electronic device may also change during the user's use of the infrared function, during the user's use of the infrared function, the emission direction of the infrared module can also be adjusted in real time, not limited to adjusting the emission direction when starting the infrared function.

[0161] In the foregoing examples, only the influence of the pitch angle on the infrared function is mentioned. Therefore, the first adjustment device and the second adjustment device can adjust the infrared emission direction to deviate or rotate along the first direction (clockwise around the Y axis) or the second direction (counterclockwise around the Y axis). In some other possible cases, the heading angle, roll angle, etc. of the electronic device may also affect the infrared function. In this case, multiple adjustment devices can also be added to adjust the emission direction of the infrared rays in the direction of the roll angle or heading angle of the electronic device.

The software instructions can be composed of corresponding software modules, and the software modules can be stored in a random access memory (RAM), flash memory, erasable programmable ROM (EPROM), electrically EPROM (EEPROM), registers, hard disk, removable hard disk, CD-ROM, or any other form of storage medium well known in the art. An exemplary storage medium is coupled to the processor so that the processor can read information from the storage medium and write information to the storage medium. Of course, the storage medium can also be a part of the processor. The processor and the storage medium can be located in an ASIC.
