The invention relates to the field of design of head up displays, in particular to a reflection screen double-rail taking-up and paying-off mechanism of a head up display. The reflection screen double-rail taking-up and paying-off mechanism of the head up display comprises a main body framework, a reflection screen and a sliding seat, wherein a first guide rail and a first guide rail rack are arranged on the lateral surface of the main body framework, a second guide rail and a second guide rail rack are arranged at the bottom of the main body framework, a first boss and a first driving gear are arranged on the lateral surface of the sliding seat, and a second boss used for being inserted into the second guide rail and a second driving gear used for being meshed with the second guide rail rack are arranged at the bottom of the sliding seat; the length of the first guide rail and the first guide rail rack is smaller than that of the second guide rail and the second guide rail rack; the reflection screen is installed at the top end of the sliding seat. By means of the technical scheme, a novel reflection screen taking-up and paying-off mode is provided, and the reflection screen is taken up and paid off along the rail and is more advanced and technical.
