When assembling, firstly, projection light source 40 is installed on one end in shell 22, adjustment mechanism 60 is installed in shell 22
Bottom；Secondly, reflecting plate 80 is fixed on the mounting portion 662 of the supporting element 66 of adjustment mechanism 60；Finally, by dodge gate 24
It is installed at the opening 226 of shell 22.
It is the use process of head-up display device 100 of the invention please refer to Fig. 3 to Fig. 5.Fig. 2 display reflection
When plate 80 is in non-display position, the closing opening of dodge gate 24, reflecting plate 80 is connected to first far from one end of mounting portion 662 and lives
On dynamic door 242.As shown in Figure 3,4, pedestal 64 is moved along sliding rail 62 towards the direction of the first dodge gate 242 under the driving of actuator 69
It is dynamic, while connecting rod 68 is rotated around its first end 682, to drive the supporting element 66 being attached thereto to move to adjust reflecting plate
80 tilt angle, even if mounting portion 662 and reflecting plate 80 are lifted, while end of the interconnecting piece 664 far from mounting portion 662 is in cunning
It is slided in road 644 along the direction of motion of pedestal 64, to realize the adjustment to 80 tilt angle of reflecting plate；With reflecting plate 80
Tilt angle variation, 80 side of reflecting plate stretched out along the constantly sliding of the first dodge gate 242 by elastic valve 2463,
In the process, the first dodge gate 242 rotates under the promotion of reflecting plate 80 around the side that it connect with shell 22, and drives the
The sliding part 2464 of two dodge gates 246 is slided along guide groove 224, at this point, sliding part 2464 acts under the guiding of guide groove 224
In third dodge gate 248, so that third dodge gate 248 is rotated clockwise around the end of its fixed part 2482 to be gradually opened opening
226；When pedestal 64 slides into the display position far from projection light source 40, dodge gate 24 is fully opened, connecting rod 68 and supporting element
66 collective effect makes reflecting plate 80 be generally in vertical expanded position, at this point, the information quilt generated by projection light source 40
Sending can be by drive link 68 to supporting element 66 and reflecting plate 80 when needing to adjust information display position to reflecting plate 80
Tilt angle be finely adjusted.
Head-up display device of the invention is equipped with the adjustment mechanism 60 for adjusting 80 tilt angle of reflecting plate, passes through
69 drive link 68 of actuator moves can be realized the adjusting of 80 tilt angle of reflecting plate, be corrected with the figure according to driver
Picture position.Meanwhile its dodge gate 24 of head-up display device 100 of the invention unlatching and closure by reflecting plate 80 movement control
System, thus its is easy to use.
It is appreciated that cabinet 20 can be omitted, projection light source 40 is directly installed on workbench by when use, adjustment mechanism
60 are oppositely arranged with projection light source 40.
It is appreciated that the movement of dodge gate 24 and elastic valve 2463 is not limited to the control of reflecting plate 80, it can also be by driving
Moving part drives with opening and closing of fault cabinet 20.
It is appreciated that the elastic valve 2463 is not limited to be provided on the second dodge gate 246, it is living that first can also be opened in
On dynamic door 242, as long as reflecting plate 80 can stretch out expansion from it.
It is appreciated that torsional spring can be omitted, third dodge gate 248, which can slide, at this time is arranged on the second dodge gate 246,
Third dodge gate 248 is driven to rotate counterclockwise with closed box 20 by the second dodge gate 246.
It is appreciated that sliding slot can be set on shell 22, sliding rail 62 is set on pedestal 64, so that pedestal 64 is in shell
22 basal slidings.
It is appreciated that the first end 682 of connecting rod 68 can also rotationally be installed in pedestal 64 close to projection light source 40
End is spaced with the interconnecting piece 664 of supporting element 66 and is arranged, and the second end 684 is rotatably supported on supporting element 66, supporting element
66 interconnecting piece 664 is rotationally connected on pedestal 64, in use, connecting rod 68 rotates under the effect of external force, to drive support
Part 66 and reflecting plate 80 rotate.
In addition, those skilled in the art can also do other variations in the present invention, certainly, these are spiritual according to the present invention
