[0041] Figure 1Schematic diagram of a light guide structure provided by an embodiment of the present disclosure. Figure 1 The light guide structure includes: a first light guide segment 11 and a second light guide segment 12.

[0042] The first light guide segment 11 has a first end 111 and a second end 112 opposite to each other;

[0043] The second light guiding segment 12 has a third end 121 and a fourth end 122 opposite to each other. The third end 121 is connected to the second end 112. The end surface of the fourth end 122 has a first light guiding region 1221 and a second light guiding region 1222. At least a portion of the orthographic projection of the first light guiding region 1221 on the plane where the first end 111 is located is located outside the end surface of the first end 111, and the orthographic projection of the second light guiding region 1222 on the plane where the first end 111 is located is located within the end surface of the first end 111.

[0044] The first light-guiding area 1221 is used for allowing the first light to propagate between the first end 111 and the fourth end 122, and a portion of the first light is reflected by the side wall of the second light-guiding segment 12 when propagating, and another portion of the first light is directly emitted between the first end 111 and the fourth end 122 when propagating; the second light-guiding area 1222 is used for allowing the second light to propagate directly between the first end 111 and the fourth end 122.

[0045] The present disclosure designs a light-guiding structure within a terminal device, wherein the light-guiding structure includes a first light-guiding segment and a second light-guiding segment that are connected. An end of the second light-guiding segment away from the first light-guiding segment can be used to set up a photoelectric device. The end face of the end has a first light-guiding area and a second light-guiding area. The first light-guiding area is used for allowing the first light to pass through. A portion of the first light is reflected by the side wall of the second light-guiding segment and propagates between the first end and the fourth end. Another portion of the first light passes directly through the first light-guiding area and the first end. The second light-guiding area is used for allowing the second light to pass through. The second light passes directly through the first light-guiding area and the first end. The above-mentioned first light and second light can belong to two photoelectric devices respectively. In this way, the two photoelectric devices reuse one light-guiding structure, and this design does not need to increase the cross-sectional area of ​​the light-guiding structure to achieve light guiding for the two photoelectric devices, thereby avoiding the waste of materials caused by setting up two light-guiding structures for the two photoelectric devices, while reducing the difficulty of subsequent hole making. Opening a hole for only one light-guiding structure makes the entire terminal device more beautiful.

[0046] like Figure 1 As shown, the sidewall of the second light guide segment 12 has a first inclined surface 123 and a second inclined surface 124 opposite to each other, and a portion of the first light is reflected by the first inclined surface 123 and the second inclined surface 124 when propagating.

[0047] Figure 2 yes Figure 1 Schematic diagram of the structure of the second light guide segment from above. Figure 1 and Figure 2 The second light guide segment 12 has a symmetrical structure. The symmetry plane of the symmetrical structure can be located in the height direction of the second light guide segment 12, and the intersection of the symmetry plane and the two end surfaces of the second light guide segment 12 bisects the two end surfaces. In the embodiment of the present disclosure, the symmetry plane of the second light guide segment 12 intersects the first inclined surface 123 and the second inclined surface 124 respectively.

[0048] like Figure 1 As shown, the end surface area of ​​the fourth end 122 is smaller than the end surface area of ​​the third end 121. The intersection line of the symmetry plane, the end surface of the fourth end 122, and the first inclined surface 123 forms a first angle 12A, and the intersection line of the symmetry plane, the end surface of the fourth end 122, and the second inclined surface 124 forms a second angle 12B. The degree of the first angle 12A is a, and the degree of the second angle 12B is b. a is less than 90°, b is greater than 90°, and a is greater than 180°-b. That is, the first angle 12A is an acute angle, and the second angle 12B is an obtuse angle. In addition, the inclination of the second inclined surface 124 is greater than the inclination of the first inclined surface 123.

[0049] Figure 3 yes Figure 1 Schematic diagram of the end surface structure of the fourth end 122. Figure 3 The first light guiding region 1221 and the second light guiding region 1222 are arranged in sequence along the intersection line L of the end face of the fourth end 122 and the symmetry plane, and the first light guiding region 1221 is close to the first inclined surface 123, and the second light guiding region 1222 is close to the second inclined surface 124.

[0050] In the embodiment of the present disclosure, the two optoelectronic device regions correspond to two optoelectronic devices, so that the end surface of the fourth end of the light-guiding structure covers the two optoelectronic device photosensitive regions at the same time.

[0051] like Figure 1 and Figure 4 As shown, according to the above-mentioned design scheme, the positive projection of the second light-guiding area 1222 on the plane where the first end 111 is located is located within the end face of the first end 111. Therefore, the light emitted by the second photoelectric device 22 can directly pass through the fourth end 122 and the first end 111 without being affected by the side wall of the second light-guiding segment 12.

[0052] like Figure 4 As shown, the light emitted by the second optoelectronic device 22 enters the light guide structure from the second light guide region 1222 and then is emitted from the end surface of the entire first end.

[0053] like Figure 1and Figure 5 As shown, the inclination of the second inclined surface 124 is greater than that of the first inclined surface 123, and the first light-guiding area 1221 is close to the first inclined surface 123, so that at least a portion of the light incident from the first end 111 is reflected by the second inclined surface 124, and then reflected by the first inclined surface 123, and finally enters the first optoelectronic device 21 from the first end 111.

[0054] like Figure 5 As shown, a portion of the light incident from the first end 111 is not affected by the sidewalls and directly passes through the first end 111 and the fourth end 122 to enter the first optoelectronic device 21 .

[0055] like Figure 5 As shown, the first end face can also be divided into two parts. A part of the incident light will enter the first optoelectronic device 21 after being reflected by the side wall of the second light guide segment 12, and the other part of the incident light will directly pass through the light guide structure and enter the first optoelectronic device 21.

[0056] from Figure 4 and Figure 5 It can be seen that although the first photoelectric device 21 and the second photoelectric device 22 each correspond to only a partial area of ​​the end surface of the fourth end, the first photoelectric device 21 and the second photoelectric device 22 each correspond to the entire area of ​​the end surface of the first end, that is, the light emitted by the photoelectric device will be emitted from the entire end surface of the first end, and the light entering the photoelectric device will also pass through the entire end surface of the first end, thereby ensuring the field of view angle of the two photoelectric devices.

[0057] In an implementation of the embodiment of the present disclosure, the first light guiding segment 11 is a cylindrical structure, and the second light guiding segment 12 is an oblique frustum structure.

[0058] like Figures 1 to 5 As shown, when the first light-guiding segment is a cylindrical structure and the second light-guiding segment is an inclined frustum structure, the aforementioned first inclined surface 123 and the second inclined surface 124 are two opposite parts of the arcuate side wall of the inclined frustum structure. The first inclined surface 123 and the second inclined surface 124 are both arcuate surfaces. The light incident on the first photoelectric device 21 will be reflected between the two opposite parts of the arcuate side wall of the inclined frustum structure.

[0059] In another implementation of the embodiment of the present disclosure, the first light guiding segment 11 is a prism structure, and the second light guiding segment 12 is an oblique pyramid structure.

[0060] Figure 6 Schematic diagram of another light guide structure provided by an embodiment of the present disclosure. Figure 6When the first light guide segment 11 is a prism structure and the second light guide segment 12 is an oblique pyramid structure, the first inclined surface 123 and the second inclined surface 124 are both planes. Light incident on the first optoelectronic device 21 is reflected between two opposite planes of the sidewalls of the oblique pyramid structure.

[0061] In the embodiment of the present disclosure, the diameter or the maximum diagonal length of the first light guide segment 11 ranges from 1.8 mm to 2.2 mm, the diameter or the maximum diagonal length of the third end 121 of the second light guide segment 12 is the same as the diameter or the maximum diagonal length of the first light guide segment 11, and the diameter or the maximum diagonal length of the fourth end 122 of the second light guide segment 12 ranges from 1.5 mm to 1.8 mm.

[0062] The light guide structure is designed according to the above size range to ensure that the opening area required for the light guide column is small enough while being able to meet the light guide requirements of two optoelectronic devices.

[0063] Exemplarily, the diameter or the maximum diagonal length of the first light guiding segment 11 is 2 mm, and the diameter or the maximum diagonal length of the fourth end 122 of the second light guiding segment 12 is 1.6 mm.

[0064] In the embodiment of the present disclosure, the height of the first light guide segment 11 ranges from 1.2 mm to 1.8 mm, and the height of the second light guide segment 12 ranges from 1.2 mm to 1.8 mm.

[0065] The light guide structure is designed according to the above size range to ensure that the light guide structure can pass through the front frame of the terminal device and can guide the light emitted by the optoelectronic device out of the terminal device, or guide the ambient light outside the terminal device into the optoelectronic device inside the terminal device.

[0066] Exemplarily, the height of the first light guiding segment 11 is 1.5 mm, and the height of the second light guiding segment 12 is 1.5 mm.

[0067] The numerical ranges of the diameter or the length of the maximum diagonal of the first light-guiding segment, the diameter or the length of the maximum diagonal of the fourth end of the second light-guiding segment, the height of the first light-guiding segment and the height of the second light-guiding segment are only one implementation method. According to the size requirements of the actual terminal device, at least one of the diameter or the length of the maximum diagonal of the first light-guiding segment, the diameter or the length of the maximum diagonal of the fourth end of the second light-guiding segment, the height of the first light-guiding segment and the height of the second light-guiding segment may also adopt other numerical values ​​outside the above numerical ranges, and the present disclosure does not impose any restrictions on this.

[0068] In the embodiment of the present disclosure, in order to meet the light guiding requirements of the light guiding structure, the light guiding structure itself is required to have good light transmittance, so the material of the light guiding structure is transparent.

[0069] In the embodiment of the present disclosure, the first angle 12A is an acute angle, and the second angle 12B is an obtuse angle. The degrees of the first angle 12A and the second angle 12B need to be designed according to actual product needs, but need to satisfy the relationship that the first angle 12A is greater than 180° minus the second angle 12B. For example, the first angle 12A is 75 degrees, and the second angle 12B is 135 degrees.

[0070] Exemplarily, the light guide structure is made of silicone, which has good light transmittance and can meet the light guiding needs of the light guide structure.

[0071] In the embodiment of the present disclosure, in addition to having good light transmittance, the light guide structure also needs the sidewall to have the ability to reflect light. To this end, the outer sidewall of the light guide structure has a high reflectivity.

[0072] Figure 7 is a cross-sectional schematic diagram of a first light guide segment of a light guide structure provided by an embodiment of the present disclosure. Figure 7 The outer wall of the light guide structure 10 has a reflective ink layer 101. The reflective ink layer 101 has a high reflectivity, so that the energy loss is minimized when light is reflected from the outer wall of the light guide structure.

[0073] The reflective ink layer 101 is formed on the outer wall of the light guide structure 10 by coating.

[0074] Figure 8 FIG is a cross-sectional schematic diagram of a first light guide segment of another light guide structure provided by an embodiment of the present disclosure. Figure 8 , the structure of the first light guide segment is compared with Figure 7 The light guide structures provided are different in that:

[0075] The outer sidewall of the light guide structure 10 further has an acrylic layer 102 , ie, a polymethyl methacrylate (PMMA) layer. The acrylic layer 102 is located between the light guide structure 10 and the reflective ink layer 101 .

[0076] The acrylic layer 102 has a harder surface than the silicone layer and can serve as the outer shell of the light guide structure, making the entire light guide structure stronger. At the same time, the acrylic layer 102 has good light transmittance and does not affect the light guide performance of the entire light guide structure 10.

[0077] In another possible implementation, an acrylic layer 102 is further provided on the outer sidewall of the light guide structure 10 , and the reflective ink layer 101 is located between the acrylic layer 102 and the light guide structure 10 .

[0078] Figure 9Schematic diagram of another light guide structure provided by an embodiment of the present disclosure. Figure 9 , compared with the light guide structure Figure 1 The light guiding structure further includes a third light guiding segment 13.

[0079] The third light guide segment 13 has a fifth end 131 and a sixth end 132 opposite to each other. The fifth end 131 is connected to the fourth end 122 . The end surface area of ​​the sixth end 132 is larger than that of the fifth end 131 .

[0080] In this implementation, a third light guide segment is provided on one side of the fourth end, and the end face area of ​​one end of the third light guide segment connected to the second light guide segment is smaller than the end face area of ​​the other end, thereby increasing the end face area of ​​the end of the light guide structure facing the optoelectronic device, thereby facilitating the reception of light emitted by the optoelectronic device, or facilitating the transmission of light to the optoelectronic device.

[0081] See again Figure 9 The orthographic projection of the fifth end 131 of the third light guiding segment 13 on the plane where the sixth end 132 of the third light guiding segment 13 is located is located within the end surface of the sixth end of the third light guiding segment 13 .

[0082] The present disclosure provides a terminal device, which includes: Figures 1 to 9 Any of the light guide structures, the first optoelectronic device and the second optoelectronic device shown.

[0083] The first optoelectronic device corresponds to the first light guiding area, and the second optoelectronic device corresponds to the second light guiding area.

[0084] Exemplarily, the first optoelectronic device faces the first light guiding area, and the second optoelectronic device faces the second light guiding area.

[0085] Exemplarily, the terminal device includes but is not limited to a mobile phone, a tablet computer, etc.

[0086] The present disclosure designs a light-guiding structure within a terminal device, wherein the light-guiding structure includes a first light-guiding segment and a second light-guiding segment that are connected. An end of the second light-guiding segment away from the first light-guiding segment can be used to set up a photoelectric device. The end face of the end has a first light-guiding area and a second light-guiding area. The first light-guiding area is used for allowing the first light to pass through. A portion of the first light is reflected by the side wall of the second light-guiding segment and propagates between the first end and the fourth end. Another portion of the first light passes directly through the first light-guiding area and the first end. The second light-guiding area is used for allowing the second light to pass through. The second light passes directly through the first light-guiding area and the first end. The above-mentioned first light and second light can belong to two photoelectric devices respectively. In this way, the two photoelectric devices reuse one light-guiding structure, and this design does not need to increase the cross-sectional area of ​​the light-guiding structure to achieve light guiding for the two photoelectric devices, thereby avoiding the waste of materials caused by setting up two light-guiding structures for the two photoelectric devices, while reducing the difficulty of subsequent hole making. Opening a hole for only one light-guiding structure makes the entire terminal device more beautiful.

[0087] In a possible implementation of the present disclosure, the first optoelectronic device is an infrared lamp, and the second optoelectronic device is an ambient light sensor.

[0088] In the embodiment of the present disclosure, the ambient light sensor has at least one of the following functions: detecting the brightness of the ambient light, detecting the color temperature, and detecting the spectrum. The infrared light emitted by the infrared lamp can realize infrared remote control functions, such as remote control of a TV, air conditioner, etc.

[0089] In another possible implementation of the present disclosure, the first optoelectronic device is an ambient light sensor, and the second optoelectronic device is an infrared lamp.

[0090] In other possible implementations, the first optoelectronic device and the second optoelectronic device may also be a combination of other optoelectronic devices.

[0091] It should be noted that when the second optoelectronic device adopts a different type of optoelectronic device, the size design of the light guide structure will also be different.

[0092] Figure 10 This is a schematic diagram of the structure of a terminal device provided by an embodiment of the present disclosure. Figure 10 In addition to the light guide structure 10, the first optoelectronic device 21 and the second optoelectronic device 22, the terminal device further includes:

[0093] Screen 30, front frame 40 and middle frame 50. The front frame 40 is set between the screen 30 and the middle frame 50, and the front frame 40 is set on the edge of the screen 30. Here, "the front frame 40 is set on the edge of the screen 30" means that it is set around the screen 30 and connected to the screen 30.

[0094] A light guide hole 51 is opened on the middle frame 50, and the first end of the light guide structure 10 is located in the light guide hole 51. The fourth end (or sixth end) of the light guide structure 10 extends into the terminal device to guide the external ambient light into the ambient light sensor, or to guide the infrared light emitted by the infrared lamp out of the terminal device.

[0095] Since the light guide hole 51 is provided on the middle frame 50 , the infrared light emitted by the infrared lamp is emitted from the top of the terminal device, and the ambient light is incident into the terminal device from the top of the terminal device and enters the ambient light sensor.

[0096] Exemplarily, the screen 30 is a liquid crystal display (LCD), an organic light emitting diode (OLED) display, or other types of screens.

[0097] In the embodiment of the present disclosure, the terminal device further includes an optoelectronic device circuit board (not shown in the figure), and the first optoelectronic device 21 and the second optoelectronic device 22 are located on the optoelectronic device circuit board.

[0098] Exemplarily, the first optoelectronic device 21 and the second optoelectronic device 22 are arranged on the optoelectronic device circuit board by spot welding.

[0099] Exemplarily, the optoelectronic device circuit board is a flexible printed circuit (FPC).

[0100] In the disclosed embodiment, the terminal device further includes a mainboard (not shown in the figure), which is electrically connected to the optoelectronic device circuit board.
