Yes thats sounds like a good way to go.
How compact are they? Because i dont have any space under the lcd
And can i get them in the right size?
What about a linear actuator?
Build it inside a new back cowling, so you cant see the actuator when you look through the front windscreen at the back of the LCD screen, and you could have the linear actuator raise and lower the screen.
They are powerful, smooth, quiet, and VERY reliable. You can have them work much like a car antenna, they have 12V power all the time, with a trigger line from the car computer. When the computer is off, the actuator retracts back into the dash, when the computer is on, the actuator extends, and raises the screen from the dash.
That would be the easiest option, and it keeps the number of moving parts down, as you only have sliding channels on each side of the screen, with the actuator being the only moving part.
You can get ones with as small as a 4inch throw, so the total body length is only about 5 inches total. You would mount it behind the screen, and have it attach to the screen up at the top, making the whole unit sit behind the screen when it is down in the dash.
Just do a google search on Linear Actuators, and you will find there are a heap of sizes and stuff on offer, admittedly they aren't super cheap, but they are a part that almost never fails, and you can choose from either high speed, low force, or low speed, high force.
When I google I mostly find pneumatic ones, and the electric ones are huge! Is it not true that electric ones are built with a screw and a DC motor?
Would be great if you could point to a feasable one for this project, Chester.
My intuition is that for size requirements, best way is to build it up myself from a screw. Most mechics will be guides to let the LCD move nicely anyway, so not a lot of work to be spared there.
CD approch was interesting though. Compact, very often strong, and stroke is about right too. Maybe even guides could be reused. Almost like attaching the LCD panel on the back of it. Problem might be to find one that is not too fast...
maybe a small, compact motor like this can help?
My 2001 Mitsubishi Eclipse GT:
"The Project That Never Ends"
more projects then time!
Led Skyline Tail Lights--100%
High Power Led Reverse Lights--100%
Led third brake light--100%
Led front turn signals--0%
Well heck. In that case... Not sure about the travel:
24V but might be a good speed at 12V. Stick a couple rods on the bottom and have this against 1 rod. Snap action switches at the ends to stop it.
