It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
As shown in fig. 1 to 5, an embodiment of the present application provides an electronic device including a housing 10, a light guide 20, and infrared emission means 30, a photosensitive element 51, and a processor 40;
the inside of the shell 10 is provided with an accommodating space, and the shell 10 is provided with a light guide hole communicated with the accommodating space;
the light guide 20 is at least partially positioned in the light guide hole;
the infrared emission device 30 and the processor 40 are arranged in the accommodating space, and infrared light emitted by the infrared emission device 30 can be conducted to the outside of the shell 10 through the light guide 20;
the photosensitive element 51 is arranged on the light guide 20;
the photosensitive element 51 and the infrared emission device 30 are connected with the processor 40;
wherein, in case the light intensity of the infrared light detected by the light sensitive element 51 is lower than a preset value, the processor 40 controls the infrared emitting device 30 to increase the emission power.
The light intensity of the infrared light detected by the light sensor 51, or the light intensity of the infrared light detected by the light sensor 51, may be understood as the light intensity of the infrared light transmitted to the light guide 20, or the light intensity of the infrared light emitted via the light guide 20. Also, the light intensity may be understood as the luminous intensity of the infrared emitting device 30 in a given direction.
In the present embodiment, the light intensity of the infrared light emitted from the infrared emitting device 30 is detected by the photosensor 51 provided on the light guide 20, so as to determine whether the light intensity of the infrared light emitted from the electronic device satisfies the infrared remote control function of the intelligent home appliance such as a television, an air conditioner, and the like. For example, it may be set that the light intensity of the infrared light detected by the photosensitive element 51 is lower than a preset value, which indicates that the light intensity of the infrared light emitted by the electronic device cannot satisfy the infrared remote control function of the intelligent home appliances such as a television, an air conditioner, and the like. Therefore, when the light intensity of the infrared light detected by the photosensitive element 51 is lower than the preset value, that is, when the light intensity of the infrared light emitted by the electronic device cannot meet the infrared remote control function of the intelligent household appliance such as the television and the air conditioner, the infrared emission device 30 can be controlled to increase the emission power through processing, that is, the light intensity of the infrared light emitted by the electronic device is increased, so that the light intensity of the infrared light emitted by the electronic device can meet the infrared remote control function of the intelligent household appliance such as the television and the air conditioner, and the purpose of improving the stability of the infrared remote control function of the electronic device is achieved.
The photosensitive element 51 may be a resistor having a photoconductive effect, for example, under the irradiation of light with a specific wavelength, a carrier generated by the irradiation of light may participate in the conduction, so that the resistance value thereof is rapidly reduced. And the stronger the illumination, the lower the resistance, namely has the function that the resistance can be rapidly reduced along with the increase of the illumination intensity.
In the present application, the photosensitive element 51 may be made of a special material that is sensitive to infrared light, so that the resistance value of the photosensitive element 51 may vary with the light intensity of the infrared light irradiated onto the photosensitive element 51 when the photosensitive element 51 is irradiated with the infrared light; that is, when the light intensity of the infrared light increases, the resistance value of the photosensor 51 becomes small; and when the light intensity of the infrared light decreases, the resistance of the photosensitive element 51 increases. Therefore, detection of the light intensity of the infrared light irradiated onto the photosensitive element 51 can be achieved by detecting a change in the resistance value of the photosensitive element 51.
In some embodiments, the light guide holes provided in the housing 10 may be understood as openings provided in the housing. For example, in the case that the electronic device is a mobile phone, in order to facilitate the user to hold the mobile phone to execute the corresponding infrared remote control function, the open hole or the light guide hole can be formed in the top edge frame of the mobile phone, so that the user can hold the mobile phone like holding a remote control, further execute the corresponding infrared remote control function, and improve the operation experience of the user.
In other embodiments, the light guide 20 may be a light guide column with good light guide performance, and one end of the light guide column is disposed in the opening and forms a light emitting surface in the opening; the other end of the light guide column may be disposed opposite to the infrared emission device 30, and form a light incident surface for receiving infrared light. In addition, other light guiding structures may be disposed between the light emitting surface of the light guiding member 20 and the infrared light 30, and the light guiding structures do not have to be disposed opposite to the openings.
Further, the infrared emission device 30 may be disposed opposite to the light guide hole, so as to shorten the conduction distance from the infrared light emitted by the infrared emission device 30 to the outside of the electronic device, improve the conduction efficiency of the infrared light, and further achieve the purpose of improving the structural compactness of the electronic device.
Optionally, the light guide 20 includes a light incident surface and a light emergent surface, and the photosensitive element 51 may be disposed on the light incident surface of the light guide 20 or may be disposed on the light emergent surface of the light guide 20.
Specifically, in the case where the photosensor 51 is provided on the light-emitting surface of the light guide 20, the photosensor 51 can realize detection of the light intensity of the infrared light emitted from the light guide 20; in the case where the photosensor 51 is disposed on the light incident surface of the light guide 20, the photosensor 51 can detect the light intensity of the infrared light emitted from the light guide 20.
The location of the photosensitive element 51 on the light guide 20 may be determined according to practical design requirements, such as assembly design requirements, etc.
In addition, to further improve the detection effect of the photosensitive element 51, the photosensitive element 51 may be an annular photosensitive resistor, and the annular photosensitive resistor may be disposed in an edge area of the light emitting surface or the light entering surface of the light guide 20.
The photosensitive element 51 may be disposed on the light guide 20 through conductive silver paste, and the photosensitive element 51 may be connected with a detection circuit on a motherboard of the electronic device, so as to achieve the purpose of improving a detection result of the photosensitive element 51.

As shown in fig. 3 to 5, the embodiment of the present application further provides a control circuit, which may be applied to the above-mentioned electronic device, and which includes an infrared emitting device 30, a photosensitive element 51, a processor 40, a first protection resistor 52, a power adjusting circuit 70, an analog-to-digital converter 80, and a logic processing circuit 90;
a first end of the photosensitive element 51 is electrically connected to a first end of the first protection resistor 52, a second end of the first protection resistor is electrically connected to a first voltage output terminal 53 of the electronic device, and a second end of the photosensitive element 51 is grounded;
a first input of the analog-to-digital converter 80 is electrically connected to the first end of the photosensitive element 51, a second input of the analog-to-digital converter 80 is electrically connected to the second voltage output 54 of the electronic device, an output of the analog-to-digital converter 80 is electrically connected to a first end of the logic processing circuit 90, and a second end of the logic processing circuit 90 is electrically connected to the processor 40;
wherein, in case the photosensitive element 51 detects that the light intensity of the infrared light emitted by the infrared emitting device 30 is lower than a preset value, the processor 40 controls the infrared emitting device 30 to increase the emission power.
Specifically, processor 40 may control infrared emitting device 30 to increase the transmit power via power adjustment circuit 70.
Wherein the power adjustment circuit 70 includes an infrared emitting device 30 and other adjustment devices.
The first input end of the analog-to-digital converter 80 may obtain the voltage of the photosensitive element 51, the first input end of the analog-to-digital converter 80 may obtain the voltage of the second voltage output end 54, and the output end of the analog-to-digital converter 80 may transmit the voltage of the photosensitive element 51 obtained by the first input end and the voltage of the second voltage output end 54 obtained by the second input end to the logic processing circuit 90;
the logic processing circuit 90 is configured to compare the voltage of the photosensitive element 51 acquired by the first input end with the voltage of the second voltage output end 54 acquired by the second input end, determine that the light intensity of the infrared light emitted by the infrared emitting device 30 is lower than a preset value when the comparison result indicates that the voltage of the photosensitive element 51 acquired by the first input end is greater than the voltage of the second voltage output end 54 acquired by the second input end, and trigger the processor 40 to generate first information, where the first information is used to instruct the processor 40 to control the infrared emitting device 30 to increase the emission power, so that the light intensity of the infrared light emitted by the electronic device can meet the infrared remote control function of intelligent household appliances such as televisions and air conditioners, and further achieve the purpose of improving the stability of the infrared remote control function of the electronic device.
The first voltage output terminal 53 and the second voltage output terminal 54 may be voltage output ports on the electronic device, such as output ports of a power supply circuit on a motherboard of the electronic device.
In one example, the second voltage output 54 may also be an output of a battery on the electronic device, such as a positive output of the battery. Where the second voltage output 54 is the positive output of the battery, the negative electrode of the battery is grounded.
The first protection resistor 52 plays a role of protecting the photosensitive element 51 and preventing the photosensitive element 51 from being burnt out under the condition of overlarge resistance change.
For example, when the infrared light emitted from the infrared emitting device 30 irradiates the photosensitive element 51, the obtained voltage signal may be converted into a digital signal by the analog-to-digital converter 80, and transmitted to the logic processing circuit 90 to perform analysis and judgment, and judge whether the interrupt control command needs to be sent to the processor 40. And under the condition that an interrupt control instruction needs to be sent to the processor 40, that is, the analysis result of the logic processing circuit 90 indicates that the voltage of the photosensitive element 51 acquired by the first input end is greater than the voltage of the second voltage output end 54 acquired by the second input end, the processor 40 can generate first information based on the interrupt control instruction so as to realize adjustment of the transmitting power of the infrared transmitting device 30, that is, control the infrared transmitting device 30 to increase the transmitting power, so that the light intensity of infrared light emitted by the electronic equipment can meet the infrared remote control function of intelligent household appliances such as televisions, air conditioners and the like, and further the purpose of improving the stability of the infrared remote control function of the electronic equipment is achieved.
Optionally, as shown in fig. 3, the power adjustment circuit 70 includes a first MOS transistor 71, a source of the first MOS transistor 71 is electrically connected to the first end of the infrared emission device 30, a drain of the first MOS transistor 71 is grounded, a gate of the first MOS transistor 71 is electrically connected to the processor 40, and a second end of the infrared emission device 30 is electrically connected to the third voltage output end 55 of the electronic device.
The third voltage output terminal 55 may be a voltage output port on the electronic device, such as an output port of a power supply circuit on a motherboard of the electronic device.
In this embodiment, the processor 40 may output a pulse width adjustment signal to adjust the resistance of the first MOS transistor 71, thereby adjusting the current of the path of the infrared emission device 30, and achieving the purpose of adjusting the emission power of the infrared emission device 30.
Optionally, the power adjustment circuit further includes a second protection resistor 72, where the second protection resistor 72 is connected in series with the infrared emission device 30 to achieve the purpose of protecting the infrared emission device 30.
When the light intensity of the infrared light detected by the photosensitive element 51 is lower than the preset value, that is, when the light intensity of the infrared light emitted by the electronic device cannot meet the infrared remote control function of the intelligent household appliance such as the television and the air conditioner, the processor 40 can output a pulse width adjustment signal to reduce the resistance of the first MOS tube 71 so as to increase the current of the channel where the infrared emission device 30 is located, thereby achieving the purpose of increasing the emission power of the infrared emission device 30, so that the light intensity of the infrared light emitted by the electronic device can meet the infrared remote control function of the intelligent household appliance such as the television and the air conditioner.
Further, as shown in fig. 4, the power adjustment circuit further includes a first voltage management unit 73 electrically connected to the processor 40, and the processor 40 may adjust the output voltage of the infrared emitting device 30 through the first voltage management unit 73. For example, when the light intensity of the infrared light detected by the photosensitive element 51 is lower than the preset value, the output voltage of the infrared emission device 30 may be changed by the first voltage management unit 73 to increase the current of the path where the infrared emission device 30 is located, so as to achieve the purpose of increasing the emission power of the infrared emission device 30.
In other embodiments, as shown in fig. 5, the power adjustment circuit further includes a second MOS transistor 74 and a second voltage management unit 75 electrically connected to the processor 40, wherein a source of the second MOS transistor 74 is electrically connected to the third voltage output terminal 55, a drain of the second MOS transistor 74 is electrically connected to the second terminal of the infrared emitting device 30, and a gate of the second MOS transistor 74 is electrically connected to the second voltage management unit 75.
Thus, the output voltage of the second voltage management unit 75 can be adjusted by the processor 40, and the resistance value of the second MOS tube 74 can be adjusted by the output voltage of the second voltage management unit 75, so as to realize the adjustment of the current of the path where the infrared emission device 30 is located, thereby achieving the purpose of adjusting the emission power of the infrared emission device 30. For example, when the light intensity of the infrared light detected by the photosensitive element 51 is lower than the preset value, the output voltage of the second voltage management unit 75 may be increased to decrease the resistance value of the second MOS transistor 74, that is, increase the current of the path where the infrared emission device 30 is located, so as to achieve the purpose of increasing the emission power of the infrared emission device 30.
Accordingly, in the case where the emission power of the infrared emission device 30 needs to be reduced, the output voltage of the second voltage management unit 75 may be reduced to increase the resistance value of the second MOS transistor 74, so as to achieve the purpose of reducing the current of the path where the infrared emission device 30 is located.
In an actual application scenario, an infrared remote control application of the electronic device is started, a remote control circuit is executed to control an initialization action, and the voltage of the photosensitive element 51 is detected every 5 seconds.
After the initialization is completed, if the voltage of the photosensitive element 51 acquired by the first input end is detected to be less than or equal to the voltage of the second voltage output end 54 acquired by the second input end, it is determined that the transmitting power of the infrared transmitting device 30 can meet the requirement of the effective control distance at this time, and the logic control circuit 90 does not feed back any interruption to the processor 40; if it is detected that the voltage of the photosensitive element 51 acquired by the first input end is greater than the voltage of the second voltage output end 54 acquired by the second input end, it is determined that the light intensity of the infrared light emitted by the infrared light 30 at this time cannot support the effective control distance, that is, the emission power of the infrared emission device 30 needs to be raised.
Specifically, in the case where it is detected that the voltage of the photosensitive element 51 obtained at the first input terminal is greater than the voltage of the second voltage output terminal 54 obtained at the second input terminal, the logic control circuit 90 triggers a control interrupt to the processor 40, and the processor 40 performs an action of adjusting the pulse width adjustment signal.
For example, the duty cycle time of the duty cycle of the pulse width adjustment signal may be gradually adjusted according to an adjustment amplitude of 1%; in the adjustment process, the detection time of the voltage of the photosensitive element 51 may be adjusted to 20 ms/each time, and as the duty ratio of the pulse width adjustment signal is raised, the first MOS tube 71 is gradually opened, the on-resistance of the first MOS tube 71 is gradually reduced, the emission power of the infrared emission device 30 is gradually increased, and the light intensity of the infrared light emitted by the infrared emission device 30 is gradually increased.
As the light intensity of the infrared light emitted by the infrared emission device 30 is gradually increased, the resistance value of the photosensitive element 51 is gradually reduced, and when the voltage of the photosensitive element 51 acquired by the first input end is detected to be smaller than or equal to the voltage of the second voltage output end 54 acquired by the second input end, it is determined that the light intensity of the infrared light emitted by the infrared emission device 30 can meet the requirement of effective control distance; at this point, an interrupt is triggered to the processor 40 to cause the processor 40 to cease the duty cycle action of adjusting the pulse width adjustment signal and save the current duty cycle as the default initialization duty cycle for the infrared remote control application.
In addition, the adjustment flow can be repeated along with the state change of the electronic equipment, and a self-adaptive design scheme is formed, so that the aim of improving the infrared remote control experience of a user is fulfilled.
It should be noted that the above detection parameters (detection time interval, preset voltage, preset value) and adjustment range may be set based on actual requirements, and are not limited herein.
Referring to fig. 6, fig. 6 is a flowchart of a power control method according to an embodiment of the present application, where the power control method may be applied to the control circuit described above, and the control circuit includes a photosensitive element, an infrared emitting device, and a power adjustment circuit, and as shown in fig. 1, the power control method includes the following steps:
In this embodiment, when the light intensity of the infrared light detected by the photosensitive element is lower than a preset value, that is, when the light intensity of the infrared light emitted by the electronic device cannot meet the infrared remote control function of the intelligent household appliance such as the television and the air conditioner, the emission power of the infrared emitting device can be increased through the power adjusting circuit, that is, the light intensity of the infrared light emitted by the electronic device is increased, so that the light intensity of the infrared light emitted by the electronic device can meet the infrared remote control function of the intelligent household appliance such as the television and the air conditioner, and the purpose of improving the stability of the infrared remote control function of the electronic device is achieved.
It should be noted that, the power control method provided in the embodiment of the present application may also implement the related control flow of the electronic device and achieve the corresponding effect, which is not described herein again.
According to the power control method, the light intensity of infrared light emitted by the infrared emission device is detected based on the photosensitive element; and under the condition that the light intensity is lower than a preset value, increasing the transmitting power of the infrared transmitting device through the power adjusting circuit. Therefore, the purpose of improving the stability of the infrared remote control function of the electronic equipment can be achieved.
