The plurality of first magnetic blocks 5 are all slidably embedded in the side wall of the heat sink 2 along the horizontal direction of the heat sink 2. The sliding stroke of the first magnetic block 5 matches the sliding stroke of the card slot 403; multiple first magnetic blocks 5 are slidably embedded in the side wall of the heat sink 2 along the horizontal direction of the heat sink 2, and the sliding stroke of the first magnetic block 5 matches the sliding stroke of the card slot 403; the mobile phone support frame 3 is fixedly connected to the center of the inner cavity of the heat sink 2, the charging module 301 is fixedly embedded in the bearing surface of the mobile phone support frame 3, and the wiring terminal of the charging module 301 extends to the outer side wall of the heat sink 2; the fill light 6 is fixedly embedded on one side surface of the baffle 4, the solar panel 7 is fixedly attached to the other side surface of the baffle 4 away from the fill light 6, and the two ends of the rotating rod 401 are rotatably connected to the corresponding fixed block 402 through damping bearings;A fixing plate 101 is fixedly connected to the top end face of the triangular bracket 1.

[0019] In low-light or nighttime live streaming scenarios, the baffle 4 assembly, which integrates the supplementary light 6 and the solar panel 7, can be magnetically attached to the left and right sides of the heat sink 2 via the first magnetic block 5 and the second magnetic block 501 inside the heat sink 2. Simultaneously, the slot 403 on the fixing block 402 is slidably fitted onto the outer surface of the second limiting rod 405 at the bottom of the heat sink 2, completing the mechanically assisted fixation. Then, the illumination angle of the supplementary light 6 can be adjusted by rotating the damping rotation structure between the rod 401 and the fixing block 402 to adapt to the supplementary lighting needs of different live streaming scenarios. In high-light or daytime live streaming scenarios, the baffle 4 assembly can be removed from both sides of the heat sink 2, adjusted in installation direction, and slid onto the top position of the heat sink 2. The slot 403 is then slidably fitted onto the outer surface of the second limiting rod 405 at the top of the heat sink 2.

[0020] During equipment installation, the fixing plate 101 is fixed to the top of the triangular bracket 1, the heat sink 2 is rotatably embedded inside the fixing plate 101, the output shaft of the drive motor 102 is fixedly connected to the bottom surface of the heat sink 2, and then the sensor 8 and the drive motor 102 are electrically connected. After the live broadcast is started, the sensor 8 will collect the face position information in the screen in real time. When the live broadcast personnel move or move within the recognition range, the sensor 8 will transmit the position change signal to the drive motor 102 in real time. The output shaft of the drive motor 102 will drive the heat sink 2 to rotate synchronously along the rotation center of the fixing plate 101, so that the heat sink 2 and the internally fixed mobile phone support 3 and mobile phone are always facing the live broadcast personnel, realizing the live broadcast positioning. The fully automatic follow adjustment; through the above technical solution, the anchor can move freely within the recognition range, display scenes or products, adapt to various live broadcast content formats such as outdoor store visits, talent shows, and product demonstrations, which can enhance the expressiveness of the live broadcast content.

[0021] Before live streaming, the phone is fixed to the phone support frame 3 inside the heat dissipation bracket 2, and the phone and the charging module 301 embedded in the phone support frame 3 are electrically connected to each other, so that the phone can be continuously powered during the live stream. During the live stream, the fan blades 201 inside the heat dissipation bracket 2 rotate continuously, forming a forced convection airflow channel to actively dissipate heat from the phone under high load during the live stream. In daytime shading mode, the solar panel 7 on the baffle 4 converts solar energy into electrical energy, simultaneously powering the supplementary light 6, charging module 301, drive motor 102, and heat dissipation fan blades 201, forming a full-link synergy of energy collection, storage, and utilization. Through the above technical solution, the active heat dissipation structure can quickly remove the heat generated by the phone during the live stream, reducing the heat generated by the phone due to heat. High-load operation can lead to overheating, frequency throttling, and shutdown. This helps ensure the stability of equipment operation during long-term outdoor live streaming. The solar power supply and charging module 301 work together to provide real-time power to the equipment in strong light conditions, alleviating the battery life pressure of multiple devices such as the fill light 6, drive motor 102, and cooling fan blades 201 operating simultaneously. This can extend the battery life of outdoor live streaming. At the same time, the cooling duct and the position of the phone support bracket 3 are matched, which can directly act on the core heat-generating area of ​​the phone. In addition, the heat dissipation structure and the charging module 301 can work together to automatically increase the speed of the fan blades 201 in fast charging mode, enhance the heat dissipation effect, reduce the decrease in charging power caused by the phone overheating during fast charging, and improve charging efficiency and safety.

[0022] Working principle: In low-light or nighttime live streaming scenarios, the baffle 4 assembly integrating the supplementary light 6 and solar panel 7 can be magnetically attracted and fixed to the left and right sides of the heat sink 2 by the first magnetic block 5 and the second magnetic block 501 inside the heat sink 2. At the same time, the slot 403 on the fixing block 402 is slidably fitted onto the outer surface of the second limiting rod 405 at the bottom of the heat sink 2 to complete the mechanically assisted fixation. Then, the illumination angle of the supplementary light 6 can be adjusted by rotating the damping rotation structure between the rotating rod 401 and the fixing block 402 to adapt to different lighting conditions. For live streaming scenarios requiring supplemental lighting; in scenarios with strong light or daytime live streaming, remove the baffle 4 component from both sides of the heat sink 2, adjust the installation direction, and slide it onto the top of the heat sink 2. Slide the slot 403 onto the outer surface of the first limiting rod 404 at the top of the heat sink 2 to complete the fixation, so that the side of the baffle 4 with the solar panel 7 faces the direct sunlight, and the side with the supplemental light 6 faces the mobile phone screen, providing top shading for the mobile phone screen; at the same time, the solar panel 7 can receive solar radiation and convert light energy into electrical energy to power the device.

[0023] During equipment installation, the fixing plate 101 is fixed to the top of the triangular bracket 1, the heat sink 2 is rotatably embedded inside the fixing plate 101, the output shaft of the drive motor 102 is fixedly connected to the bottom surface of the heat sink 2, and then the sensor 8 and the drive motor 102 are electrically connected. After the live broadcast is turned on, the sensor 8 will collect the face position information in the screen in real time. When the live broadcast personnel move or move within the recognition range, the sensor 8 will transmit the position change signal to the drive motor 102 in real time. The output shaft of the drive motor 102 will drive the heat sink 2 to rotate synchronously along the rotation center of the fixing plate 101, so that the heat sink 2 and the internal fixed mobile phone support 3 and mobile phone are always facing the live broadcast personnel, realizing the fully automatic following adjustment of the live broadcast position.

[0024] Before the live stream, the phone is fixed on the phone support frame 3 inside the heat dissipation rack 2, and the phone and the charging module 301 embedded in the phone support frame 3 are electrically connected to each other, so that the phone can be continuously powered during the live stream. During the live stream, the fan blades 201 inside the heat dissipation rack 2 rotate continuously to form a forced convection air duct to actively dissipate heat from the phone under high load during the live stream. In the daytime shading mode, the solar panel 7 on the baffle 4 converts solar energy into electrical energy, which simultaneously supplies power to the fill light 6, the charging module 301, the drive motor 102, and the heat dissipation fan blades 201, forming a full-link synergy of energy collection, storage, and utilization.
