Description

Technical Field

[0001] This utility model belongs to the field of special vehicle technology, specifically relating to a mobile network live broadcast vehicle based on multi-functional integration. Background Technology

[0002] With the rapid development of internet technology, live streaming has become an important form of information dissemination and entertainment. For example, merchants use live streaming to promote and showcase their products, and interact with viewers in real time, thereby attracting buyers and generating orders. Meanwhile, functional live streaming rooms and live commerce have found mature applications across various industries. To adapt to the rapid development of the live streaming industry, mobile live streaming vehicles have emerged. These vehicles not only possess all the functions required for film and television production but also feature high efficiency, stability, and flexibility, greatly facilitating the production of live streaming footage. The evolution of live streaming vehicles began with the traditional cable television signal transmission mode, which relied on a fixed link architecture between ground base stations and satellite relays, resulting in rigid deployment and limited coverage. For example, in the prior art, Chinese patent application publication number CN114245037A discloses a live news broadcasting vehicle, including a broadcasting vehicle body and a lighting adjustment system. A top plate is fixedly connected to the upper surface of the broadcasting vehicle body, and a rotating mechanism is fixedly installed on the upper surface of the top plate. This patent, through the setting of a rotating motor, rotating gear, gear ring, adjusting motor, adjusting gear, first gear plate and second gear plate, etc., starts the adjusting motor to drive the adjusting gear to rotate, and the adjusting gear drives the first gear plate and the second gear plate to move and make the two solar panels on them move away from each other, and move the telescopic frame outward, thereby increasing the sunshade range of the broadcasting vehicle, while facilitating the storage of solar panels when not in use and reducing space occupation. However, the functionality of this patent technology is limited and cannot meet the needs of mobile live broadcasting and other work. Furthermore, existing traditional live broadcast vehicles focus solely on audio and video acquisition and transmission, offering limited functionality (e.g., TV live broadcast vehicles only support one-way broadcasting), failing to meet the multi-tasking demands of the converged media era. They also suffer from strong network dependence; existing equipment struggles to guarantee live broadcast continuity in areas without stable networks (such as rural areas or the wilderness), lacking multi-network redundancy transmission mechanisms. Moreover, existing live broadcast vehicles exhibit poor scene adaptability, limited spatial interactivity, and an inability to provide a horizontal work surface. The fixed broadcasting equipment typically mounted on the vehicle cannot be quickly switched to market, stage, or other formats, and training support modules are lacking. While some manufacturers have proposed the concept of internet news live broadcast vehicles, they have not addressed core issues such as multi-functional integration, extreme environment protection, and user interaction training.

[0003] In view of the above, the core problem with existing technologies lies in the significant room for improvement in terms of functional integration, space efficiency, and intelligence of current live streaming vehicles. Therefore, there is an urgent need for an innovative live streaming vehicle system capable of functional integration, spatial transformation, and end-to-end intelligent control.
