Need help with actuating a design.
(OP)
Hi all, here is a prototype. This is a pop-up gauge pod for a car, and I need some assistance in making it work!
I'm open to gas springs, torsional springs, rotary dampers, servos, linear actuators ETC. Though I prefer for the system to be self-locking at the raised and lowered positions. If not, I can use a push-to-release latch.
Here is a video of the movement. Essentially, it pivots around the back.
The space around it is limited, so I cannot mount an actuator far down on the back section of the non-moving frame to generate the moment I'd like to.
Bounce some ideas off of me.

Then, you push on the top of it to disengage the catch and the gas springs smoothly pivot the cluster up. When you're ready to close it, you just push on the top of the cluster and pivot it back down into the push-to-close latch.

I agree that gas springs would be nice, and that was my original idea, but now I'm tending towards a linear actuator with a switch.
Have any sources for small relatively inexpensive linear actuators? Something in the scale of 2-3 inches fully extended?

I'm thinking you need to use a cheap stepper motor and either a screw mechanism or a spring-loaded rack and pinion. You just need to produce some pulses with a chopper drive based on time. There shouldn't be any need for feedback.

RE: Need help with actuating a design.
There is plenty of precedent for manual pop-up stuff like this.
RE: Need help with actuating a design.
Need some help with a simple toggle-style control for the servo, though. Should I head over to the EE section, or does anyone here have some suggestions there?

Theres another idea for u , plenty of vaccuum units in climate controls.

Was told it couldnt be done, so
i went and did it!
