hiding the front license plate

HiImBrian · 05-23-2007

Well I have been driving around with my license plate in my window for a while now and I know I'm going to get pulled over sooner or later, and with my luck I wont get out of it. As a pre-mechanical engineer and a kid with a love for designing and mechanics, I am thinking about how I could design and make a device for my front license plate to slide up and down on. I have removed my worthless crash bar in the front and I have an excess amount of space right behind the front bumper above the intercooler. I have also had the idea of possibly mass producing this device to sell. Has anybody seen or thought of any possible design that could give me a start to this small project? Any help or advice would be much appreciated. Thanks

this is some james bond type shit going on here lol

what you could do is mount a bracket to a power window regulator (upside down) and hook it to a switch inside the car. press the switch and the plate would go down.

I just got pulled over a week ago for no front plate and I got a fix it ticket, I dont wanna drill through my bumper EVER for anything, so it would be cool to see something like this on the market!

good luck with it

they make something like that for hot rods. I have seen them for sale at back to the 50's every year they get good money for them though

if you do go with my idea, im taking 50% of the profits btw

HiImBrian · 05-23-2007

Haha I've thought about using the power window motor already and I was wondering if there might be anything a little faster or a different kinda of motor I could use.

Some RC car servo's could work. Its one flowed motion right? Were do you want the plate to move to?

HiImBrian · 05-23-2007

Behind the front bumper or more specifically behind the mitsu emblem. Just an up and down motion.

So mounting to heavy duty servo's that have a arm coming down to one of the mounting holes for the plate. And have them pull upward. If you want take a window track and modify it to fit in that small area. And have the plate slide along the track. The Servo's can be pretty damn fast also easy to control and not spendy...like a window track motor.

Yea the window motors are a little spendy, and if I do decided to try and mass produce these I would want the cost as cheap as possible. I am unfamiliar with the term servo. I have a few ideas of how to make brackets and mounts for the plate to attach to, I just need ideas for motors I could use. The window motor is rather large and provides more power than I really need.

Alittle Google brought me to this link Whats a Servo

And to the other comment yes a Servo needs a controler but its not that hard to mimic the same input it needs to do something. And they do stop at a point and will move back to the other point. And the cost for one is 15 dollars as the site states.

Sorry I couldn't search that earlier. I was workin. I can't stop thinking about this idea. It seems so easy yet so hard. Plus I know there would be a definate demand for something like this and if it turned out well enough I could sure use an extra buck or two

Check out my old post in this link. I actually made it so my front license plate will slide up and down on a track. The track is mounted to the back side of the bumper. I was going to make a motorized version of it over the winter but I'm still working on my motor build and never got to it. It works very slick. I came up with an idea that it will basically stay wherever you slide it to without the need for any pins or locks. Even though it's my own design, it's the best i've seen around. It works excellent for use at the track when you don't want the plate blocking your intercooler.

NOTE: It's not down all the way in the pics.

I like how you did that. Is it a law to have the whole plate showing or just the numbers? I like how you did yours. Thats pretty sweet. In a way its like the Euro plates. Oh and btw I also like to see the design of the plate braket.

Onefast99gsx · 05-23-2007

Thanks... i'm not sure if it's required to have the whole thing showing or what. I did it mainly to please the worst of all state troopers (pull ya over for anything!!) He ended up pulling me over one night saying that I was speeding thru town. I happended to be logging my fuel trims in dsmlink at the time and actually played the dsmlink log back for him to show my speed

Anyway, I got out of the car and showed him the plate mechanism I made because he pulled me over for no front plate before. He was totally cool with it, even though I trimmed the Wisconsin off the bottom. His exact words were, "At least it's there" He NEVER bothered me again about it.

If you have a FMIC, there isn't a whole lot of room to be mounting motors and stuff behind the bumper. If you run a window motor, how are you going to come up with the regulator? In otherwards, you're inside and you push a button. There would have to be some sort of a limit switch telling the motor to shut off. Servos are getting complicated because many of them work of PWM (pulse width modulation). You'd then need a circuit for that.

You might be better off with some sort of pneumatic air powered piston. Sometimes all the best ideas lead to an idea that will never get completed because of complication. That's why I just went simple. It looks good to the point where I don't mind have it the way it is.

Like I said, I took out the crash bar and I have a ton of room behind the bumper. I could fit a baby in there if I wanted.

xveganxcowboyx · 05-23-2007

For weight and ease of design I would just use a simple catch. You'd have to push it back up it's track or bracket, but would be able to just flip a switch or whatever to let it drop down.

Swifty1638 · 05-23-2007

Roll the plate at the bottom, so when you are stopped, the plate is down, but when you are driving, or on the highway, the plate (mounted on hinges) will swing up.

Somewhere is a how to out there that a guy wrote up for his BMW or something. It was hinged and spring loaded. I didn't go that route because the bumper cover ledge or whatever isn't as deep as the plate is long. So it would hung out some.

Kevin 1G Drummer · 05-23-2007

I've seen something similar to a couple suggestions on some cuztom sportbikes. It's just the plate mounted with a hinge, and they use a little servo to pull it up flush with the tail of the bike. I'm sure you could rig up something similar in the bumper opening.
