Title:
EXTENDABLE/RETRACTABLE PLATFORM AND LASER PROJECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/185695
Kind Code:
A1
Abstract:
An extendable/retractable platform (000), comprising: a fixing bracket (100), a bearing box (200), a first driving assembly (300), a sliding assembly (400), and a translation assembly (500). The fixing bracket (100) in the extendable/retractable platform (000) is used for fixing to a target plane, and the translation assembly (500) is used for bearing a laser projection main unit (002). When driven by the first driving assembly (300), the translation assembly (500) can automatically slide along a direction perpendicular to the target plane. A laser projection system (001) comprises the extendable/retractable platform (000) and the laser projection main unit (002) located on the extendable/retractable platform (000). The translation assembly (500) can conveniently adjust the position of the laser projection main unit (002) in the direction perpendicular to the target plane to cause the laser projection main unit (002) to adapt to corresponding transmittance, so that the size of a projection picture projected by the laser projection main unit (002) can match the size of a projection screen (003) fixed on a wall.
