Description

A HUD Combined Glass Retractable Mechanism

technical field

The invention relates to the field of airborne head-up display technology, in particular to a head-up display combined glass retractable mechanism.

Background technique

The head-up display of transport aircraft has functions such as auxiliary navigation, take-off and landing, etc., and can display flight information through a semi-reflective glass of the head-up display. The spectral range of information projection is very narrow, and its focus at infinity ensures that the driver will not be forced to adjust his eyes when displaying projected information, so that he can intuitively see the scene outside the glass, and the head-up display has an equiangular display with the external scene.

Due to the combined glass and retractable mechanism of the head-up display in the past, the space requirements of the aircraft cockpit are relatively large, which is suitable for large passenger aircraft of regional lines and above. For business jets, the cockpit space is small and the equipment layout is limited, so it is necessary to design a new type of retractable device. Decentralized agencies to meet the requirements of business jets.

detailed description

Embodiments of the present invention are described in detail below, and the embodiments are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

The purpose of the present invention is to propose a combination glass retractable mechanism for a head-up display. The station position of the head-up display is shown in Figure 1. The combination glass receives and projects information and reflects it to the eyes of the pilot. Rotate the operating handle so that the operating handle is in the unlocked position, operate the combined glass bracket by hand, and move it to the storage position (Figure 2), so that the combined glass can be stored in a safe position that is difficult for observers to improve the ergonomics of the device.

In order to achieve the above purpose, as shown in FIG. 3 , the head-up combined glass retractable mechanism includes a combined glass 1 , a combined glass bracket 2 , a support component 3 , an operating handle 4 and a mounting base 5 .

The combined glass bracket 2 and the combined glass 1 are connected together by bonding and fixing; the combined glass bracket 2 has a connecting ear with a central axis hole.

Described support part 3 comprises rotating shaft 9, separation wheel 12; The brackets 2 are fixed together. One end of the rotating shaft 9 is constrained by the bearing 7 , and the other end is constrained by the shaft fixing member 14 . The bearing 7 is fixedly installed on the outer end of the combined glass bracket 2 through the bearing cover 6 and the connecting flange 8, and the shaft fixing member 14 is fixed on the installation support 5 through the installation cover plate.
