Detailed description of the invention
In the present invention, the embodiment of head-up display as in Figure 3-5: the compound glass 1 that head-up display comprises impact protection apparatus, glass erecting frame 2 and is installed on glass erecting frame 2.Compound glass 1 is fixed on glass erecting frame 2 by the mode of bonding.Described impact protection apparatus comprises stationary cam 4 and the rolling disc 5 for being connected with glass erecting frame 2 during the use can rotated relative to stationary cam 4; the lever 6 that axis being parallel rolling disc 5 being hinged with axis and rolling disc 5 is arranged; stationary cam 4 is provided with cam load portion 10; lever 6 is provided with the lever pushing part coordinated with cam load portion 10; lever pushing part is rotate the roller 9 be assemblied on lever 6, and roller 9 is rotated by lever rotation axle 8 and is assemblied on lever 6.Be provided with the spring 3 making lever 6 have the trend of rotating counterclockwise between rolling disc 5 and lever 6, spring 3 is extension spring, and spring 3 is positioned at the upside of lever 6.Lever 6 has in rotation process makes lever pushing part spacing and limit the locking position that glass erecting frame 2 rotates counterclockwise by cam load portion 10, and lever 6 also has and rotated clockwise to make described lever pushing part stride across cam load portion 10 and remove the solution lock-bit spacing to glass erecting frame 2 by cam load portion 10 pushing tow in rotation process.Stationary cam 4 is fixed on airframe by cam installation shaft 15.Rolling disc 5 is provided with the first limiting section 13, and stationary cam 4 is provided with for coordinating with the first limiting section 13 block the first gear stop 11 rotated clockwise to limit glass erecting frame 2.Rolling disc 5 is provided with the second limiting section 14, and stationary cam 4 is provided with the second gear stop 14 for coordinating with second gear stop 14 block to limit the limit that glass erecting frame 2 rotates counterclockwise.
Compound glass 1 is in running order when normal work, is in guard mode when emergency deceleration.When normally working, lever pushing part is spacing by cam load portion 10, and glass erecting frame 2 can not rotate counterclockwise, and now compound glass is in the dead ahead of driver head, and now compound glass 1 is as shown in Figure 1 in running order.When there is emergency deceleration in aircraft; lever is rotated clockwise by cam load portion 10 pushing tow; lever pushing part strides across cam load portion 10 and removes spacing to glass erecting frame 2; glass erecting frame 2 and the compound glass 1 that is arranged on glass erecting frame 2 under the effect of inertia conter clockwise rotational angle a to avoid the head movement envelope region of chaufeur; now compound glass 1 is in guard mode; the head of chaufeur can be avoided like this to come to harm, as shown in Figure 2.
In other embodiments of head-up display of the present invention, spring 3 is stage clip, and the downside of lever 6 is located at by spring 3.
The structure of the embodiment of impact protection apparatus of the present invention is identical with the structure of the embodiment of head-up display, no longer repeats at this.
