And realize the linear movement of the lock arm at long axis both ends.The HUD synchronism mechanism of the utility model can not only be incited somebody to action by motor
The linear motion for being converted into lock arm of long axis converts variable curvature curve fortune for dustproof cover under the action of linear motion
It is dynamic, and the synchronism mechanism of driving device two sides can guarantee moving synchronously for card dustproof cover, and it is uneven to prevent left and right
Detent phenomenon, reliability is very high.
Detailed description of the invention
Fig. 1 is the stereoscopic schematic diagram of HUD synchronism mechanism in an embodiment.
Specific embodiment
It is further retouched in detail below in conjunction with HUD synchronism mechanism work of the specific embodiments and drawings to the utility model
It states.
Referring to Figure 1, a kind of HUD synchronism mechanism comprising for being fixed on reflecting mirror arranged on left and right sides guide rail
It is separately connected on left support 31 and right support 32, left support 31 and the bottom terminal ends of right support 32 and is relatively set with a synchronous fortune
Motivation structure 10 is provided with a driving device 20 between two synchronism mechanisms 10；Synchronism mechanism 10 includes a lock arm
11, the lock arm 11 being separately positioned on left support 31 and right support 32 is opposite and is arranged in parallel, and lock arm 11 is filled towards driving
It sets and is connected with two rack gears 12 that are parallel and being oppositely arranged in 20 one side wall；Driving device 20 includes that a section is in six sides
The long axis 23 of shape is connected separately with a straight-tooth gear 24 on two ends of long axis 23, and straight-tooth gear 24 is engaged in corresponding
Between two rack gears 12, rotation 23 synchronous drive straight-tooth gear 24 of long axis rotation, the rotation of straight-tooth gear 24 then drives lock arm 11
On rack gear 12 linearly move.
Driving device 20 further includes motor 25, motor gear 21, first bevel gear 22 and second bevel gear 26, the first cone tooth
Wheel 22 and the centerline axis parallel of motor gear 21 are arranged, and the central axis of long axis 23 and the central axis of first bevel gear 22 hang down
Straight setting；One end of first bevel gear 22, which is formed on the lateral wall of conical tooth, the other end, is formed with straight-tooth, motor gear 21 with
