Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
For an electronic device provided with an optical sensor, it is necessary to provide a light-transmitting area on the electronic device, through which light from the optical sensor is emitted. In the prior art, the light-transmitting area is generally disposed on a display panel of the electronic device, so that the optical sensor can conveniently detect the use scene of the electronic device. However, if the optical sensor is mounted on the electronic device in the above-mentioned mounting manner, the display area of the electronic device needs to be occupied, which imposes a great limitation on the electronic device.
Taking a single-screen mobile phone as an example, as shown in fig. 1, in a conventional single-screen mobile phone, the mobile phone includes a first side (i.e. a side where a display 11 of the mobile phone is located) and a second side (i.e. a side where a rear cover of the mobile phone is located, which is not shown in the figure), and an optical sensor, such as an infrared proximity sensor 12, is usually disposed on the first side of the mobile phone. The infrared proximity sensor 12 is usually placed side by side with the receiver 13, and the sensing direction of the infrared proximity sensor 12 is consistent with the sound emitting direction of the receiver 13, so as to detect the approach action of a user, and intelligently extinguish the display screen 11 during a call, so as to achieve the purposes of saving power and preventing a user from hanging up the call due to facial mistouch.
In the above conventional arrangement, the light emitting surface of the infrared proximity sensor 12 generally faces the first side of the mobile phone, and a light transmitting area, such as an optical opening, is generally required to be disposed on the frame 111 on the top of the display 11 on the first side of the mobile phone, and the optical opening needs to occupy the display area on the first side of the mobile phone. The screen occupation ratio of the mobile phone is limited, and the integral feeling of the whole mobile phone is influenced due to the fact that the optical opening is required to be formed in the first side of the mobile phone. With the increasing demand of users for the size of display screens, the design of full-screen becomes the mainstream in the future. The above-described existing arrangement forms a conflict with the design of a full screen.
In view of this, the following technical solutions are provided in embodiments of the present invention to solve the above problems.
As shown in fig. 2, an embodiment of the present invention provides an electronic device 2, where the electronic device 2 includes a first side 23 and a second side 28 that are opposite to each other, and a frame 22 is disposed between the first side 23 and the second side 28;
the optical sensor 21 is assembled inside the electronic device 2, and a light-emitting surface 211 of the optical sensor 21 faces the frame 22 of the electronic device 2, so as to avoid a light-transmitting area for the optical sensor 21 to emit light from being opened on the first side 23 of the electronic device 2;
the frame 22 is provided with a light guide hole 221 for the light guide member 24 to be embedded in, the light guide member 24 is at least partially embedded in the light guide hole 221, and the light guide member 24 includes an incident surface 241 facing the light emitting surface 211 and an emitting surface 242 facing the outside of the frame 22;
the central axis of the light emitting surface 211 deviates from the central axis of the light guiding hole 221 in a direction away from the first side 23, and at least a portion of the light emitted from the optical sensor 21 is deflected and emitted out toward the plane of the first side 23 of the electronic device 2 through the light emitting surface 242 of the light guiding member 24.
For an electronic device used on one side, the first side of the electronic device may refer to a side of the electronic device for a user to use and operate, and is generally a front side of the electronic device, and the second side of the electronic device may refer to a back side of the electronic device. For a single-screen electronic device, the side of the electronic device where the display screen is located is typically the first side of the electronic device, such as a computer, a television, an automated teller machine, a cell phone, a tablet, a wearable device, and so on. For the dual-screen electronic device, the first side of the electronic device may refer to a side where one display screen is located, and the second side of the electronic device may refer to a side where the other display screen is located. The embodiment of the present invention is not limited thereto.
The embodiment of the invention is suitable for most electronic equipment needing to be provided with the optical sensor, and the electronic equipment can be electronic equipment with a fixed position, such as a computer, a television, an automatic teller machine, an automatic induction water faucet and the like, and can also be electronic equipment with a movable position, such as handheld electronic equipment (such as a mobile phone, a tablet personal computer and the like), wearable electronic equipment (such as an intelligent bracelet, a telephone watch and the like) and the like.
In the embodiment of the present invention, the light guide 24 is made of a light-transmitting material with a good light-guiding effect, such as glass, Polymethyl methacrylate (PMMA), Polycarbonate (PC), and the like. The light guide 24 includes an incident surface 241 facing the optical sensor 21 and an exit surface 242 facing the outside of the electronic device 2. When the light emitted from the optical sensor 21 passes through the incident surface 241 and the exit surface 242, a refraction phenomenon occurs.
In the embodiment of the present invention, the light emitting surface 211 is deviated from the light guiding hole 221 in the direction away from the first side 23, so that the light near the first side 23 (or the light toward the first side 23) of the light emitted by the optical sensor 21 is obliquely incident into the light guiding member 24 and is emitted through the light guiding member 24, and most of the light emitted from the light guiding member 24 is directed toward the plane where the first side 23 is located. Thus, in the embodiment of the present invention, the actual detection area of the optical sensor 21 is deviated to the plane of the first side 23 to form an asymmetric optical sensor detection area, so that the optical sensor 21 can detect the usage scenario of the first side 23 of the electronic device.
In the embodiment of the invention, through the technical scheme, the first side of the electronic equipment is not required to be provided with the light-transmitting area for the optical sensor to emit light, so that the problem that the space of the first side of the electronic equipment is required to be occupied by the conventional optical sensor assembling mode is solved. When the first side is the side where the display screen is located, the display area of the electronic equipment is not occupied due to the arrangement of the optical sensor, so that the screen occupation ratio of the electronic equipment can be improved.
In an embodiment of the present invention, the optical sensor 21 may be an infrared proximity sensor. The infrared proximity sensor can sense the proximity capacity of an object, so that the proximity of the object can be responded correspondingly, the infrared proximity sensor can be arranged on handheld communication electronic equipment such as a mobile phone and a tablet personal computer, can also be arranged on an automatic induction water faucet, and can also be arranged in the fields of television remote control, motion sensing games and the like.
In the embodiment of the present invention, as shown in fig. 3, the electronic device 2 may be a handheld electronic device, the first side 23 of the electronic device 2 is provided with a display 25 and a receiver 26, and the receiver 26 is disposed at the same end as the optical sensor 21. In fig. 3, the optical sensor 21, i.e. the infrared proximity sensor, is arranged on top of the electronic device 2, with the optical sensor detection zone 212 facing asymmetrically towards the side of the earpiece 26 and having an overlap area with the earpiece radiation zone 261, so that the infrared proximity sensor is able to detect this action of the human ear 3 approaching the earpiece 26 when answering a call.
In general, the optical sensor 21 is used to detect the usage scenario of the first side 23 of the electronic device, so that for the electronic device 2, the light rays directed to the plane of the first side 23 are useful light, and the light rays directed to the plane of the second side 28 are useless light, so that as few light rays as possible can be emitted toward the plane of the second side 28. In addition, for the handheld electronic device, when the user uses the electronic device, the user usually places his hand on the back of the electronic device, and in order to avoid false detection, the light of the optical sensor 21 should be prevented from being emitted toward the plane of the second side 28.
In view of this, in the embodiment of the invention, the central axis of the light emitting surface 211 may deviate from the entire light guiding hole 221 in the direction away from the first side 23.
Since the light ray at the central axis of the light emitting surface 211 is substantially perpendicular to the light guide 24, the light ray is substantially parallel to the plane of the first side 23 of the electronic device when being emitted through the light guide 24. Therefore, when the central axis of the light emitting surface 211 deviates from the whole light guiding hole 221 in the direction away from the first side 23, the light rays located on the central axis of the light emitting surface 211 away from the first side 23 will be shielded by the frame 22, and the light rays emitted toward the plane of the second side 28 can be reduced as much as possible.
In the electronic device 2, the more light rays are emitted toward the plane of the first side 23, the higher the detection sensitivity of the optical sensor 21, and the better the detection effect, so that the more light rays can be emitted toward the plane of the first side 23 as much as possible.
In view of this, in the embodiment of the present invention, the distance between the light guide hole 221 and the first side 23 may be shorter than the distance between the light guide hole 221 and the second side 28, or the light guide hole 221 may be closer to the first side 23 of the first side 23 and the second side 28. In this way, of the light emitted by the optical sensor 21, the light near the first side 23 and located on the central axis of the light emitting surface 211 can be deflected as much as possible toward the plane where the first side 23 is located.
Optionally, the exit surface 242 is an arc surface, and the exit surface 242 smoothly transitions with the surface of the frame 22. Thus, the exit surface 242 and the surface of the frame 22 can jointly form a continuous surface, thereby improving the appearance performance of the whole electronic device.
Optionally, the exit surface 242 is a convex arc surface, and the exit surface 242 gradually shifts toward the side where the optical sensor 21 is located in the direction from the first side 23 to the second side 28.
By using the light-gathering principle of the convex lens, the emitting surface 242 has the light-gathering function, so that the light emitted from the light guide 24 is deflected toward the first side 23 to a greater extent, and thus, the central angle of the emitted light can be effectively controlled, and the detection effect of the optical sensor 21 is improved. The curvature of the exit surface 242 can be fine-tuned according to different requirements, and the curvature of the exit surface 242 is usually in the range of 0.01 to 10.
Optionally, as shown in fig. 4, the light guide 24 further includes a reflecting surface 243, the reflecting surface 243 and the emitting surface 242 form an obtuse angle, and at least a part of the light emitted by the optical sensor 21 is reflected toward the plane where the first side 23 is located through the reflecting surface 243.
With the above arrangement, at least a portion of the light emitted by the optical sensor 21, which is located on the central axis of the light emitting surface 211 and away from the first side 23, is incident on the reflecting surface 243, and the reflecting surface 243 reflects the light and then emits the light through the light emitting surface 242 of the light guide 24. The light beam is originally emitted in a direction away from the first side 23, and is deflected to be emitted towards the plane of the first side 23 after being reflected once, so that the light beam becomes effective light beam. This can further increase the amount of light emitted toward the plane of the first side 23, thereby further improving the detection sensitivity and detection effect of the optical sensor 21.
In the embodiment of the present invention, the forming of the reflecting surface 243 may include at least the following embodiments.
In one embodiment, as shown in fig. 5, light guide 24 is made of a high refractive index material, and the refractive index of light guide 24 is greater than or equal to 1.2 and less than or equal to 3.0. The high refractive index material may be PC or an optical fiber. By using a high refractive index material, total reflection may occur on the reflecting surface 243 when the incident angle of the light incident on the reflecting surface 243 among the light emitted from the optical sensor 21 is larger than the critical angle.
In the case where light guide 24 is made of a high refractive index material, the light exit angle of optical sensor 21 and the degree of inclination of reflecting surface 243 satisfy the following conditions:
of the light rays emitted from the optical sensor 21, the incident angle of the light ray incident on the reflecting surface 243 is larger than the critical angle. As shown in fig. 5, the incident angle θ1And angle of incidence theta2Are all larger than the critical angle.
In another embodiment, as shown in fig. 6, a mirror coating or a mirror film layer is provided on the reflecting surface 243 of the light guide 24, and the reflecting surface 243 can be made to be specularly reflecting by providing the mirror coating or the mirror film layer.
In another embodiment, the inner wall 222 of the light guide hole 221 connected to the reflecting surface 243 is polished, for example, metal polished, so that the inner wall 222 of the light guide hole 221 has high light reflection.
As another embodiment, as shown in fig. 7, the inner wall 222 of the light guide hole 221 connected to the reflecting surface 243 is provided with a mirror coating or a mirror film layer, so that the inner wall 222 of the light guide hole 221 realizes mirror reflection.
Optionally, light guide 24 is bonded to bezel 22; alternatively, light guide 24 is injection molded to bezel 22.
However, in the method of bonding light guide 24 to frame 22, the contact area between light guide 24 and frame 22 may be increased as appropriate in order to increase the bonding strength between light guide 24 and frame 22. For example, the light guide 24 may be extended inside the electronic device 2 in the manner shown in fig. 2, and the extended portion of the light guide 24 may contact the inner sidewall of the frame 22. In addition, in order to improve the waterproof performance of light guide hole 221, light guide 24 may be provided with a waterproof step shown in fig. 2.
In addition, a certain safety distance should be kept between the light guide 24 and the optical sensor 21 to prevent the light guide 24 and the optical sensor 21 from being damaged when the electronic device is dropped carelessly or collided by an external force.
In an embodiment of the present invention, the electronic Device may be a Computer (Computer), a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal digital assistant (PDA for short), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), an electronic reader, a navigator, a digital camera, and the like.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
