[0002] With the development of smart phones, the black borders of touch screens (TouchPad, TP) are getting narrower and narrower, and the proportion of the display screen is getting larger and larger; in this case, the light-sensing structure and space on the top of the phone are greatly compressed; in addition, in order to meet users' demands for the appearance and functions of mobile phones, the design of mobile phones is becoming more and more complicated, but this also brings some technical problems.

[0003] Deficiencies of existing technology:

[0004] 1. Poor light transmission effect: Since the space at the top of the phone is compressed, the light transmission effect of the light sensor may be affected, resulting in a decrease in the performance of the phone's light sensing function.

[0005] 2. Poor waterproof and dustproof effect: Existing mobile phone designs may not take into account the waterproof and dustproof requirements of the photo sensor. Therefore, when the mobile phone is used in harsh environments, rain and dust may enter the photo sensor, affecting its performance and may even cause damage to the phone.

[0006] 3. Complex structure and difficult assembly: As the design of existing mobile phones becomes more and more complex, the assembly process becomes more and more difficult, which not only increases the production cost but also may affect the quality of the mobile phone.

[0058] Combination Figure 1-5 As shown, the utility model provides a light-guiding structure of a smart phone, comprising: a light-guiding column 1, used to guide light to a photosensitive device 3 inside the mobile phone; a photosensitive sleeve 2, which is sleeved on the outside of the light-guiding column 1; the photosensitive sleeve 2 and the light-guiding column 1 are interference-fitted, the photosensitive device 3 is located at the bottom of the light-guiding column 1, and the light-guiding column 1 and the photosensitive device 3 are both located inside the photosensitive sleeve 2, thereby achieving waterproof and dustproof properties while guiding light.

[0059] The light guide column 1 includes two light guide strips 101, and the bottoms of the two light guide strips 101 are connected by a connecting plate 102, so that the light guide column 1 is U-shaped as a whole. The light guide column 1 is made of a light-transmitting material, and the light sensing sleeve 2 is made of an opaque material. The light sensing sleeve 2 is provided with two mutually isolated light guide holes 201 for accommodating the two light guide strips 101 to prevent each other from stealing light. An anti-fool strip 202 is also provided at a corner of the bottom of the light sensing sleeve 2 to prevent reverse installation. The top edges of the light guide column 1 and the light sensing sleeve 2 are both provided with chamfers for easy assembly.

[0060] The connecting plate 102 is provided with a first step 103 , and the inner side of the corresponding photosensitive sleeve 2 is provided with a first groove 203 for guiding and positioning during the assembly process.

[0061] like Figure 6-8 As shown, the utility model also provides a mobile phone, adopting the above-mentioned light-guiding structure, including: a touch screen 4, a display screen 5, a cover 6, and a PCB board 7 arranged in sequence from top to bottom; a light-transmitting photosensitive area 401 is arranged on the top of the touch screen 4, and the photosensitive area 401 does not have a display screen 5; the photosensitive device 3 is mounted on the PCB board 7, the light-guiding column 1 is mounted on the photosensitive device 3, and the photosensitive sleeve 2 is sleeved on the outside of the two; a light-transmitting port 601 is arranged at a position on the cover 6 corresponding to the photosensitive sleeve 2; light passes through the photosensitive area 401 of the touch screen 4 and reaches the photosensitive device 3 from the light-guiding column 1.

[0062] The outer side of the light sensing sleeve 2 is provided with a second step 204, and the light transmission opening 601 of the housing 6 is provided with a second groove 602 for guiding and positioning during assembly. The housing 6 is also provided with a sheet metal part 8 for reinforcing the housing 6.

[0063] The principle of this utility model is as follows:

[0064] 1. Light guidance: In the light guiding structure of the smartphone, the light guide column 1 made of a light-transmitting material is responsible for effectively concentrating and guiding the ambient light entering from the photosensitive area 401 at the top of the touch screen 4. Since the light guide column 1 is designed as a U-shape as a whole, with two light guide bars 101 connected at the bottom by a connecting plate 102, it can capture and conduct light more fully.

[0065] 2. Light isolation and focusing: Two independent light guide holes 201 are provided inside the photosensitive sleeve 2, and each light guide hole 201 accommodates a light guide bar 101, which can ensure that light from different directions or areas will not interfere with each other and is directly and effectively transmitted to the photosensitive device 3 located at the bottom of the light guide column 1.

[0066] 3. Sealing and protection: The light sensing sleeve 2 and the light guide column 1 are installed by interference fit to form a close contact surface to achieve a waterproof and dustproof effect, protecting the internal light sensing device 3 from the external environment.

[0067] 4. Precise assembly: During the assembly process, the first step 103 on the connecting plate 102 matches the first groove 203 on the inner side of the photosensitive sleeve 2, playing a positioning and guiding role, ensuring that the light guide column 1 can be accurately inserted into the photosensitive sleeve 2 and maintain a stable position relationship.

[0068] 5. Foolproof design: The foolproof strip 202 at the bottom of the optical cover 2 ensures that it can only be installed in the correct way during assembly, avoiding functional failure caused by reverse installation.

[0069] 6. Integrated: The entire light guide structure is wrapped by the light sensing cover 2 and precisely matched with other components of the mobile phone such as the PCB board 7 and the cover 6. The cover 6 is provided with a light-transmitting port 601 corresponding to the position of the light sensing cover 2, allowing external light to pass through the touch screen 4 and then smoothly reach the light guide column 1, and finally be transmitted to the photosensitive device 3.

[0070] 7. Mechanical stability and appearance craftsmanship: A sheet metal part 8 is added to the face shell 6 to enhance the structural stability; at the same time, chamfers are set on the top edges of the light guide column 1 and the light sensing sleeve 2, which is convenient for assembly and takes into account the aesthetics of the product.
