Abstract

The invention discloses a reflective screen retracting / spreading device of a head-up display. The device comprises a bottom shell, a reflective screen and a screen bracket for fixing the reflective screen, wherein guide slots are formed in the inner walls on the two sides of the bottom shell; parallel screw rod and guide rail extending longitudinally are arranged at the bottom of the bottom shell; one end of the screw rod is connected with a motor; a sliding seat is arranged on the guide rail; a threaded hole meshed with the screw rod is formed in the sliding seat; the screen bracket is connected with the sliding seat through a rotation shaft to realize two states of backward lying and standing; guide wheels positioned in the guide slots are arranged on the two sides of the screen bracket respectively; and the guide slots are bent grooves gradually turning up at the back. The device disclosed by the invention has the advantage that the reflective screen can be retracted into the shell of the head-up display when the head-up display is not in use; and therefore, the head-up display is more beautiful and offers better scientific and technological sense.

Description

technical field [0001] The invention belongs to the technical field of head-up displays, in particular to a reflective screen retractable device for head-up displays. Background technique [0002] Head-up display, also known as Head Up Display (HUD) for short, is a flight auxiliary instrument commonly used on aircraft at present. It is a kind of electronic component, display component, controller, high-voltage power supply, etc. Integrated electronic display device. It can project information such as flight parameters, aiming attack, and self-inspection in the form of images and characters to the optical / electrical display device on the combined glass directly in front of the cockpit through optical components. When the pilot observes the scene outside the cabin through the combination glass, he can see the characters, images and other information superimposed on the exterior scene at the same time. And the projection focal length is located in the front of the imaging com...
