The invention discloses a multifunctional conference room with changeable modes. The multifunctional conference room comprises a conference room body, and three-dimensional projector equipment, a conference table and chairs are arranged in the conference room body. The multifunctional conference room is characterized in that a conference table lifting mechanism, a chair stretching mechanism and a three-dimensional projector equipment lifting mechanism are arranged in the conference room body, the conference table is connected with the conference table lifting mechanism, the chairs are connected with the chair stretching mechanism, and the three-dimensional projector equipment is connected with the three-dimensional projector equipment lifting mechanism. According to the multifunctional conference room, the hexagon inlay design is adopted, and the efficient special utilization is achieved; the conversion among various conference table modes is flexible and fast, the mechanisms are concise and compact, and the transmission efficiency is high; a glass curtain can be rolled and unrolled steadily and rapidly and is made of semitransparent materials, therefore, projecting is clear, the communication of a speaker behind the curtain is achieved, and the problem that the communication contents are covered due to the communication in front of the curtain is solved.
