Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined. Example

[0030] See also Figure 1-3 As shown, the utility model provides a technical solution of a soft film light box with a heat dissipation mechanism: a soft film light box with a heat dissipation mechanism, comprising a frame 1, a lamp body 2 is arranged inside the frame 1, a heat dissipation mechanism 3 is designed on the outside of the lamp body 2, and a soft film adjustment mechanism 4 is installed on the outside of the heat dissipation mechanism 3;

[0031] The heat dissipation mechanism 3 includes an air inlet 301, an air outlet 303, and a light-transmitting cover 305. The air inlet 301 is provided on the frame 1, and an exhaust fan 302 is installed inside the air inlet 301. The air outlet 303 is provided on the frame 1, and an exhaust fan 304 is installed inside the air outlet 303. The light-transmitting cover 305 is arranged on the outside of the lamp body 2, and the light-transmitting cover 305 isolates the lamp body 2 from the soft film adjustment mechanism 4 inside and outside. The outer part of the light-transmitting cover 305 is provided with an air inlet end 306 and an air outlet end 307, and the air inlet end 306 is connected to the exhaust fan 302. The air outlet 307 is connected to the exhaust fan 304. During the operation of the soft film light box, the lamp body 2 will emit heat. At this time, the exhaust fan 302 of the air inlet 301 of the light-transmitting cover 305 and the exhaust fan 304 at the air outlet 303 work simultaneously to promote the air circulation inside the light-transmitting cover 305 and accelerate the gas flow to achieve the heat dissipation effect on the lamp body 2. On the other hand, since the soft film adjustment mechanism 4 is located on the outside of the light-transmitting cover 305, the gas flow will not affect the soft film adjustment mechanism 4 during the heat dissipation process, thereby ensuring the normal operation of the light box.

[0032] The soft film adjustment mechanism 4 includes a first rotating rod 401, a soft film 403, a plurality of positioning rods 404, and a motor 405. The first rotating rod 401 is installed on the side of the light-transmitting cover 305, and the second rotating rod 402 is installed on the other side of the light-transmitting cover 305. One end of the soft film 403 is connected to the first rotating rod 401, and the other end of the soft film 403 is connected to the second rotating rod 402. The positioning rod 404 is installed on the upper end of the light-transmitting cover 305. The positioning rod 404 is used to prevent the soft film 403 from directly contacting the light-transmitting cover 305. The motor 405 is arranged on the inner side of the frame 1. The output end is connected to the first rotating rod 401. In the specific implementation process, the first rotating rod 401 and the second rotating rod 402 can be connected by a chain belt to achieve synchronous rotation. When adjusting the picture of the soft film 403, the motor 405 drives the first rotating rod 401 and the second rotating rod 402 to rotate. At this time, the picture of the soft film 403 will change the display surface along the rotation direction to meet the needs of different display effects. On the other hand, the establishment of the positioning rod 404 can ensure that the soft film 403 is always in a three-dimensional state and does not contact the light-transmitting cover 305, providing a better display effect.

[0033] Filters 5 are provided at the air inlet 301 and the air outlet 303 , which can prevent impurities in the air from entering the light-transmitting cover 305 during the heat dissipation process, thereby maintaining the internal cleanliness of the light-transmitting cover 305 and reducing the influence of impurities on the light transmission performance of the light-transmitting cover 305 .

[0034] The light cover 305 is made of polycarbonate material. This design can ensure the light transmittance of the light cover 305, ensure the uniform distribution and effective transmission of light inside the light box, and also has good heat resistance, and can withstand the heat from the lamp body 2 without deformation. In addition, the high impact strength of polycarbonate ensures the durability and impact resistance of the light cover 305 during the heat dissipation process.

[0035] A support plate 6 is provided on the lower end surface of the frame 1. This design can provide a solid support for the light box and enhance the stability of its overall structure, ensuring that the light box maintains its structural integrity and functions unaffected under adverse external weather conditions, such as rainy days, strong winds or extreme temperature changes.

[0036] The air inlet end 306 and the air outlet end 307 of the light-transmitting cover 305 are both designed with large and small openings. This design optimizes the air flow speed by adjusting the difference in the diameters of the air inlet end 306 and the air outlet end 307, thereby improving the cooling efficiency inside the light-transmitting cover 305, helping to maintain low-temperature operation of the lamp body 2, extending the life of the lamp body 2 and maintaining stable lighting effects.

[0037] The working principle of the utility model is as follows:

[0038] When the soft film light box with a heat dissipation mechanism of this embodiment is used, the entire light box system is first started by power supply. When the lamp body 2 is lit, the surrounding air temperature will begin to rise due to its heat. In order to control the temperature of the lamp body 2, the induced fan 302 and the exhaust fan 304 will be started. The induced fan 302 is located inside the air inlet 301 and is responsible for sucking external cold air into the light-transmitting cover 305. When the cold air flows in the light-transmitting cover 305, it absorbs the heat generated by the lamp body 2, and then the heated air is led to the air outlet 307, and finally discharged from the light-transmitting cover 305 by the exhaust fan 304 located at the air outlet 303. 5. This continuous air circulation process effectively accelerates the gas flow, thereby improving the heat dissipation efficiency of the lamp body 2. On the other hand, the operation of the soft film adjustment mechanism 4 is independent of the heat dissipation mechanism. The motor 405 drives the first rotating rod 401 and the second rotating rod 402. The two rotating rods are connected by a chain belt to ensure synchronous rotation. The soft film 403 adjusts its display surface according to the required display effect through the rotation of the first rotating rod 401 and the second rotating rod 402. The positioning rod 404 ensures that the soft film 403 always maintains a three-dimensional state and prevents it from directly contacting the light-transmitting cover 305 to avoid damage to the soft film 403 due to heat conduction.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
