AI Technical Summary
Existing live streaming backdrop setup solutions rely on fixed scenes or large backdrops, which are bulky and difficult to carry, limiting the flexibility of broadcasters to conduct live streams in different locations. Furthermore, setting up and dismantling them requires specialized tools and time, increasing preparation costs and difficulty. Traditional backdrops are fixed and difficult to expand or contract to increase usable area and richness, thus limiting creativity and visual effects.
The portable backdrop design includes an L-shaped upright panel, a sliding rail, a movable backdrop, a servo motor-driven gear system, and a roller structure. This allows for automatic adjustment and expansion of the backdrop. The servo motor drives the gears to mesh with the gear plate, enabling the movable backdrop to slide within the sliding rail. The rollers provide guidance, and the movable pull rod provides support, thus achieving adjustable and expandable backdrop functionality.
It achieves portability and flexibility of the backdrop, reduces the space occupied by the equipment, simplifies the setup process, improves the creativity and visual effects of the live broadcast, enhances the sense of layering and richness of the background, and improves the quality of the live broadcast.
