Therefore, the electronic equipment disclosed by the application can solve the problem that the electronic equipment provided with two display screens in the related technology needs two light sensors, so that the production cost of the electronic equipment is high.
In a further embodiment, the light-conducting member 400 may further include a second light-guiding portion 420, and the second light-guiding portion 420 may be disposed between the light sensor 300 and the second light-transmitting region 221, so that the light transmitted through the second light-transmitting region 221 may be conducted to the light sensor 300 through the second light-guiding portion 420. Alternatively, the second light guide 420 may be a second light guide pillar. In this case, loss of light during transmission can be reduced.
As described above, the first display 210 and the second display 220 are disposed on two opposite sides of the first housing 110, and the light sensor 300 is disposed in the first housing 110, so that the light sensor 300 is disposed between the first display 210 and the second display 220, and the second light-transmitting area 221 is opposite to the light sensing surface of the light sensor 300, that is, the second display 220 is opposite to the light sensing surface of the light sensor 300, and the first display 210 is disposed on one side facing away from the light sensing surface of the light sensor 300.
Therefore, the first light guide portion 410 needs to extend from a side of the photosensor 300 facing away from the photosurface to a side of the photosensor 300 facing the photosurface. In order to achieve the above object, the first light guide portion 410 may be provided as a bending structure, and the bending structure may include a plurality of bending sections connected in sequence. For example, the first light guiding portion 410 may include a first section 411 and a second section 412, an included angle may be formed between the first section 411 and the second section 412, the first section 411 may be opposite to the first light transmitting region 211, and the second section 412 may be connected to the second light guiding portion 420, so that the light transmitted through the first light transmitting region 211 sequentially passes through the first section 411, the second section 412 and the second light guiding portion 420 to be transmitted to the light sensor 300. In this case, the direction of the first light guide 410 determines the direction of the light, so that the direction of the first light guide 410 can be designed according to the specific space in the first housing 110, and the space of the first housing 110 can be fully utilized.
In a further embodiment, the included angle between the first section 411 and the second section 412 may be an acute angle, and the second section 412 may be inclined toward one side of the light sensing surface of the light sensor 300. In this case, the light can be prevented from being projected to the side wall of the second light guiding portion 420 as much as possible, so that as much light as possible is directly projected to the end of the second light guiding portion 420 facing the light sensor 300, and further the loss of the light in the transmission process is reduced.

The circuit board 500 may include a first board 510, a second board 520, and a side 530 connected between the first board 510 and the second board 520, wherein the first section 411 of the first light guiding portion 410 extends from a first side of the first board 510 to a second side of the second board 520, and the first section 411 is in limiting contact with the side 530. In this case, the contact of the first section 411 with the side 530 of the circuit board 500 proves that the light guide 400 moves to a predetermined mounting position during the mounting of the light guide 400, and the light guide 400 can be more simply and precisely mounted to the predetermined mounting position.

The light guide 400 may further include a supporting frame 430, the supporting frame 430 is supported on the circuit board 500, and the supporting frame 430 and the circuit board 500 enclose an accommodating space 600, the light sensor 300 is disposed in the accommodating space 600, and the first light guide portion 410 and the second light guide portion 420 may be connected to the supporting frame 430, so as to facilitate installation of the first light guide portion 410 and the second light guide portion 420. In this case, the optical sensor 300 is disposed in the accommodating space 600, so that the optical sensor 300 is protected, and the circuit board 500 can play a role of assisting in forming the accommodating space 600, thereby achieving the purpose of multiple purposes.
In a further technical solution, the first housing 110 may include a first support 111, where the first support 111 is provided with an avoidance hole communicated with the accommodating space 600, and the second light-transmitting area 221 is opposite to the avoidance hole, so that light transmitted through the second light-transmitting area 221 can be injected into the accommodating space 600 through the avoidance hole, the support frame 430 is positioned between the first support 111 and the circuit board 500, and at least part of the second light guiding portion 420 is located in the avoidance hole, so that the light sequentially passes through the second light-transmitting area 221, the avoidance hole and the second light guiding portion 420 to be injected into the light sensor 300. In this case, after the support frame 430 is mounted on the circuit board 500, the first support 111 is fastened to the support frame 430, so as to position the support frame 430, thereby facilitating positioning and assembling of the support frame 430.
In an alternative embodiment, the electronic device may further include a first focusing lens 710, where the first focusing lens 710 is disposed in the first housing 110 and opposite to the first light-transmitting region 211, and the light passing through the first light-transmitting region 211 may sequentially pass through the first focusing lens 710 and the first light guiding portion 410 and be projected onto the light sensor 300.

Alternatively, the optical path adjusting member 730 may be a focusing mirror. In this case, the light emitted through the first focusing lens 710 can be totally reflected by the reflecting surface 731 to the photosensor 300, so that the loss of the light in the transmission process is reduced, and the response speed of the photosensor 300 can be further improved.
In an alternative embodiment, the electronic device may further include a second focusing lens 720, where the second focusing lens 720 is disposed in the first housing 110 and opposite to the second light-transmitting area 221, and the light passing through the second light-transmitting area 221 may sequentially pass through the second focusing lens 720 and the second light-guiding portion 420 and be projected to the light sensor 300. In this case, the loss of light during the transmission process can be reduced, and the focusing effect of the second focusing lens 720 is beneficial to improving the response speed and the angle of view of the light sensor 300.
The light guide 400 has a light emitting surface 440 facing the light sensor 300, and the light emitting surface 440 may be provided with a diffusion layer 450. Alternatively, the diffusion layer 450 may be a diffusion ink layer or a diffusion film. In this case, the diffusion layer 450 can diffuse the light, so that the light guided out through the second light guide 420 is more uniform.
In a further aspect, the electronic device may further include a first infrared emitter 810 and a second infrared emitter 820 disposed within the first housing 110. The first infrared emitter 810 is disposed opposite to the first light-transmitting area 211, and is configured to emit infrared light to a side of the first display screen 210 outside the electronic device, and the second infrared emitter 820 is disposed opposite to the second light-transmitting area 221, and is configured to emit infrared light to a side of the second display screen 220 outside the electronic device. The light sensor 300 may include an infrared sensor, where the infrared sensor is configured to receive infrared light, and after the infrared light emitted by the first infrared emitter 810 or the second infrared emitter 820 is reflected by the detected object, the infrared light can be projected to the infrared sensor, and the infrared sensor controls the first display screen 210 or the second display screen 220 to stop according to the shielding condition of the first display screen 210 or the second display screen 220.
For example, when the electronic device is on, and the first display screen 210 is in a bright screen state, the user blocks the first display screen 210 during the call answering process, and after at least part of the infrared light projected by the first infrared emitter 810 is reflected by the user, the infrared light is projected to the infrared sensor through the first light-transmitting area 211 and the first light-guiding portion 410 in sequence, and the infrared sensor controls the first display screen 210 to stop the screen. Similarly, when the electronic device is on, and the second display screen 220 is in the bright screen state, the user shields the second display screen 220 in the process of answering the call, and after at least part of the infrared light projected by the second infrared emitter 820 is reflected by the user, the infrared light sequentially passes through the second light transmission area 221 and the second light guide part 420 to be projected to the infrared sensor, and the infrared sensor controls the second display screen 220 to be on screen. In this case, it can be avoided that the first display screen 210 or the second display screen 220 is in a bright screen state in the incoming call process of the electronic device, and the user touches the first display screen 210 or the second display screen 220 by his limb, so that the phone hangs up or other functions are triggered by mistake.
Referring to fig. 1 and 2 again, the electronic device may further include a second housing 120, where the second housing 120 is rotatably connected to the first housing 110, and a direction indicated by an arrow in fig. 1 is a direction in which the first housing 110 and the second housing 120 rotate relative to each other, so that the electronic device is switched between an unfolded state and a folded state.
Under the condition that the electronic device is in the unfolded state, the first infrared emitter 810 is turned on, the second infrared emitter 820 is turned off, at least part of the infrared light projected by the first infrared emitter 810 is reflected by the detection object, and then projected to the infrared sensor through the first light transmission area 211 and the first light guide part 410 in sequence, and the infrared sensor judges the shielding condition outside the first display screen 210 according to the reflected infrared light, so as to judge whether to control the first display screen 210 to stop the screen. Under the condition that the electronic equipment is in a folded state, the first infrared emitter 810 is closed, the second infrared emitter 820 is opened, at least part of infrared light projected by the second infrared emitter 820 is reflected by a detection object and then projected to the infrared sensor through the second light transmission area 221, and the infrared sensor judges the shielding condition outside the second display screen 220 according to the reflected infrared light, so as to judge whether to control the second display screen 220 to stop the screen.
For example, in the case where the electronic device is in the unfolded state and a shielding object such as a book exists on the opposite side of the first display screen 210, at least a portion of the infrared light projected by the first infrared emitter 810 is reflected by the shielding object and then projected to the infrared sensor, and the infrared sensor controls the first display screen 210 to stop. Similarly, when the electronic device is in a folded state and a shielding object such as a book exists on the opposite side of the second display screen 220, at least part of the infrared light projected by the second infrared emitter 820 is reflected by the shielding object and then projected to the infrared sensor, and the infrared sensor controls the second display screen 220 to stop.
Alternatively, the second infrared emitter 820 is turned off with the first infrared emitter 810 turned on, and the first infrared emitter 810 is turned off with the second infrared emitter 820 turned on, that is, the first infrared emitter 810 and the second infrared emitter 820 cannot be simultaneously turned on. In the case where infrared detection is required on both the first display screen 210 side and the second display screen 220 side, the first infrared emitter 810 and the second infrared emitter 820 may be alternately turned on. In this case, the power consumption of the first infrared emitter 810 and the second infrared emitter 820 can be reduced, and the endurance of the electronic device can be enhanced.
In a further aspect, the light-conducting member may further include a third light guiding portion 460, the third light guiding portion 460 being opposite to the second light-transmitting region 221, and the third light guiding portion 460 being opposite to the second infrared emitter 820. In this case, the infrared light emitted from the second infrared emitter 820 or the loss of the infrared light entering the electronic device through the second light transmitting region 221 during the conduction can be reduced. The third light guide part 460 may be disposed at a distance from the second light guide part 420. In this case, the problem of light interference due to mutual light channeling can be avoided.
The light sensor 300 includes a visible light sensor, a detection device, a processing device, and a control device.
Wherein the detection means is for detecting a current inclination angle of the first housing 110 with respect to the vertical direction. In the embodiment disclosed in the present application, the first display screen 210 and the second display screen 220 are respectively disposed at opposite sides of the first housing 110, that is, the detection device can detect the current inclination angles of the first display screen 210 and the second display screen 220 with respect to the vertical direction. Alternatively, the detection device may be at least one of an accelerometer or a gyroscope.
The visible light sensor is used to detect the amount of visible light passing through the first light-transmitting region 211 and the second light-transmitting region 221.
The detection device and the visible light sensor are both electrically connected with the processing device, and the detection device can transmit the current inclination angle information to the processing device, and the visible light sensor can transmit the visible light amount information to the processing device, where the processing device is used for calculating the first ambient brightness in the direction of the first display screen 210 and the second ambient brightness in the direction of the second display screen 220, and specifically, the processing device calculates the first ambient brightness and the second ambient brightness according to the formula (1) and the formula (2), respectively.
Formula (1): a=a×k1;
Formula (2): b=a×k2;
