In the embodiment of the present invention, the light guide 24 is made of a transparent material with good light guiding effect, such as glass, Polymethyl methacrylate (PMMA), Polycarbonate (PC), etc. the light guide 24 includes an incident surface 241 facing the optical sensor 21 and an emergent 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 emergent surface 242, the refraction phenomenon occurs.
In the embodiment of the present invention, in the light emitted by the optical sensor 21, at least part of the light will be incident on the reflecting surface 243, and the reflecting surface 243 will reflect the light and then emit the light through the emitting surface 242 of the light guide 24. Therefore, in the embodiment of the present invention, the actual detection area of the optical sensor 21 is deviated to the plane where the first side 23 is located, so as to form an asymmetric optical sensor detection area, thereby enabling the optical sensor 21 to detect the usage scenario of the first side 23 of the electronic device.
The embodiment of the utility model provides an in, through above-mentioned technical scheme, need not to set up the printing opacity region that supplies optical sensor light-emitting in electronic equipment's first side to solved the problem that current optical sensor assembly methods need occupy electronic equipment first side space. 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 the 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 screen 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 the embodiment of the present invention, the formation of the reflecting surface 243 may include at least the following embodiments.
In one embodiment, as shown in fig. 4, 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. 4, the incident angle θ1And angle of incidence theta2Are all larger than the critical angle.
In another embodiment, as shown in fig. 5, the reflecting surface 243 of the light guide 24 is provided with a mirror coating or a mirror film layer, and the reflecting surface 243 can be made to be mirror-reflective 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. 6, 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.
Generally, the optical sensor 21 is used for detecting the usage scenario of the first side 23 of the electronic device, so that, for the electronic device 2, the light emitted toward the plane of the first side 23 is useful light, and the light emitted toward the plane of the second side 28 is useless light, so that more light can be emitted toward the plane of the first side 23 and less light 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 present invention, the central axis of the light emitting surface 211 may fall in the area where the reflecting surface 243 is located.
In this way, on the one hand, most of the light rays emitted by the optical sensor 21 far from the first side 23 can be incident on the reflecting surface 243, so that the emission amount of the effective light rays is increased; on the other hand, among the light rays emitted by the optical sensor 21, the light rays close to the first side 23 (or the light rays facing the first side 23) are obliquely incident into the light guide 24 and are emitted out through the light guide 24, so that the part of the light rays face the plane of the first side 23 to become effective light rays. As can be seen, this embodiment can greatly increase the amount of effective light emitted and improve the operability of the optical sensor 21.
For the electronic device 2, the more light rays 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 guiding hole 221 and the first side 23 may be shorter than the distance between the light guiding hole 221 and the second side 28, or the light guiding 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, 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.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
