The invention relates to the field of design of head up displays, in particular to a reflection screen taking-up and paying-off mechanism of a head up display. The reflection screen taking-up and paying-off mechanism of the head up display comprises a main body framework, a sliding seat, a reflection screen assembly, a motor and a transmission gear, wherein a guide rail is formed in the lateral surface of the main body framework, a lead screw is arranged on the bottom surface of the main body framework, the sliding seat is provided with a through hole, and a thread is formed in the inner wall of the through hole; the lead screw is sleeved with the sliding seat through the through hole, and the thread on the inner wall of the through hole is meshed with the lead screw; the bottom end of the reflection screen assembly is movably connected with the sliding seat; a sliding shaft used for being inserted into the guide rail is arranged on the lateral surface of the reflection screen assembly; the motor is arranged in the main body framework, connected with the lead screw through the transmission gear and used for driving the lead screw to rotate. By means of the technical scheme, a novel reflection screen taking-up and paying-off mode is provided, and a reflection screen is taken up and paid off along the rail and is more advanced and technical.
