For the description of the embodiments disclosed in the technology of the present invention, please refer to FIG. 1 to FIG. 9 together.

As shown in FIGS. 1-9, the portable electronic device 1 of the present invention is, for example, a smart phone capable of receiving luminous signals. Among them, the portable electronic device 1 includes: a device body 11, a light guide element 12, and Optical signal transceiver 13. The device body 11 has a display screen 111 and a body frame 112. The main body frame 112 extends along the outer edge of the display screen 111 to provide positioning and protection for the display screen 111, and the main body frame 112 has a light-through hole structure 1121.

The light guide element 12 can be used to guide light signals. In the present invention, the main system of the light guide element 12 is embedded in the main body frame 112 and has a first refraction surface 121, a second refraction surface 122, a total reflection surface 123, an accommodating space 124, and an optical column 125, respectively. The first refraction surface 121 is exposed from the body frame 112 and avoids the display screen 111 to avoid the provision of the first refraction surface 121 to reduce the screen-to-body ratio of the display screen 111. The accommodating space 124 is used for accommodating the optical signal transceiver 13, and the second refraction surface 122 is disposed on the wall surface of the light guide element 12 forming the accommodating space 124 so as to face the optical signal transceiver surface of the optical signal transceiver 13. Preferably, the first refraction surface 121, the second refraction surface 122, and the total reflection surface 123 are respectively formed on the three end surfaces of the optical column 125 to reduce the difficulty of manufacturing the light guide element 12.

The optical signal transceiver 13 is, for example, a distance sensor, and its main system is embedded in the body frame 112 to send a first optical signal R1 to an object 2 such as a user or receive a second optical signal R2 from the object 2. Preferably, the second optical signal R2 is generated by the reflection of the first optical signal R1 traveling to the object 2. Therefore, the distance of the object 2, such as the distance, can be determined by the difference between the first optical signal R1 and the second optical signal R2 Waiting for the state.

Specifically, the first optical signal R1 travels toward the second refraction surface 122 from the optical signal transceiver 13 and then enters the second refraction surface 122. By the refraction of the second refraction surface 122, the first optical signal R1 is directed toward the entire The reflecting surface 123 travels. As shown in FIGS. 6 and 8, because the medium of the path before and after the first optical signal R1 enters the second refraction surface 122 changes, the incident angle θ11 of the first optical signal R1 on the second refraction surface 122 is substantially greater than that of the refraction surface 122. The angle θ12 allows the first optical signal R1 to travel toward the total reflection surface 123 in a predetermined direction.

Then, the first optical signal R1 is incident on the total reflection surface 123. By the total reflection of the total reflection surface 123, the first optical signal R1 travels toward the first refraction surface 121, and then enters the first refraction surface 121. The refraction of a refraction surface 121 causes the first light signal R1 to travel toward the object 2. The first refraction surface 121 is exposed by the light through hole structure 1121, so that the first light signal R1 leaves the device body 11 and travels toward the object 2 , So that the optical signal transceiver 13 completes sending the first optical signal R1 to the object 2. As shown in FIGS. 6 and 8, because the medium of the path before and after the first optical signal R1 is incident on the first refraction surface 121 changes, the incident angle θ13 of the first optical signal R1 on the first refraction surface 121 is substantially smaller than that of the refraction surface. The angle θ14 allows the first optical signal R1 to travel toward the object 2 in a predetermined direction.

As shown in FIGS. 6 and 8, the incident angle θ1r of the first optical signal R1 on the total reflection surface 123 is substantially equal to the intersection angle α between the second refraction surface 122 and the total reflection surface 123, and the first optical signal R1 is refracted at the second The sum of the refraction angle θ12 on the surface 122. The incident angle θ13 of the first optical signal R1 on the first refraction surface 121 is substantially equal to the difference between the intersection angle γ of the first refraction surface 121 and the total reflection surface 123 and the incident angle θ1r of the first optical signal R1 on the total reflection surface 123 . Therefore, the traveling direction of the first optical signal R1 is related to the inclination angles of the first refraction surface 121, the second refraction surface 122, and the total reflection surface 123, so it is only necessary to adjust the first refraction surface 121, the second refraction surface 122, and the The inclination angle of the total reflection surface 123 can ensure that the first optical signal R1 travels toward the object 2 in a predetermined direction and avoids the display screen 111.

In addition, the second optical signal R2 travels from the object 2 toward the first refraction surface 121, and then enters the first refraction surface 121. By the refraction of the first refraction surface 121, the second optical signal R2 travels toward the total reflection surface 123. As shown in FIGS. 7 and 9, because the medium of the path before and after the second optical signal R2 is incident on the first refraction surface 121 will change, the incident angle θ24 of the second optical signal R2 on the first refraction surface 121 is substantially greater than that of the refraction. The angle θ23 allows the second optical signal R2 to travel toward the total reflection surface 123 in a predetermined direction. It should also be noted that the first refraction surface 121 is exposed by the optical through hole structure 1121, so that the second optical signal R2 enters the device body 11 and travels toward the optical signal transceiver 13, so that the optical signal transceiver 13 is completed. The second optical signal R2 from the object 2 is received.

Then, the second optical signal R2 is incident on the total reflection surface 123, and by the total reflection of the total reflection surface 123, the second optical signal R2 travels toward the second refraction surface 122, and then enters the second refraction surface 122. The refraction of the two refraction surfaces 122 causes the second optical signal R2 to travel toward the optical signal transceiver 13 so that the optical signal transceiver 13 completes the reception of the second optical signal R2 from the object 2. As shown in FIGS. 7 and 9, because the medium of the path before and after the second optical signal R2 is incident on the first refraction surface 121 will change, the incident angle θ22 of the second optical signal R2 on the second refraction surface 122 is substantially smaller than that of the refraction surface. The angle θ21 allows the second optical signal R2 to travel toward the optical signal transceiver 13 in a predetermined direction.

As shown in Figures 7 and 9, the incident angle θ2r of the second optical signal R2 on the total reflection surface 123 is substantially equal to the intersection angle α between the second refraction surface 122 and the total reflection surface 123. The sum of the incident angle θ22 on the surface 122. The refraction angle θ23 of the second optical signal R2 on the first refraction surface 121 is substantially equal to the difference between the intersection angle γ of the first refraction surface 121 and the total reflection surface 123 and the incident angle θ2r of the second optical signal R2 on the total reflection surface 123 . The traveling direction of the second optical signal R2 is related to the inclination angles of the first refraction surface 121, the second refraction surface 122 and the total reflection surface 123, so it is only necessary to adjust the first refraction surface 121, the second refraction surface 122 and the total reflection surface. The inclination angle of the surface 123 can ensure that the second optical signal R2 travels toward the optical signal transceiver 13 in a predetermined direction and avoids the display screen 111.

In summary, the portable electronic device of the present invention is capable of receiving luminous signals. The light guide element mainly provides two-stage refraction and one-stage total reflection for the optical signal, so that the optical signal can avoid the display screen and pass through the main body. The frame enters and exits the device body, that is, the optical signal transceiver of the portable electronic device of the present invention avoids the display screen and receives light signals through the frame of the body. In this way, the screen ratio of the display screen can be effectively increased, and the display screen can be reduced. The production cost of the screen.
