Car Backseat Automatic Table

By

Before reading about automatic tray table refer to previous posts about how to install manual car backseat tray table  .
to install automatic operating system first install a rod across strips like in image
rod for rotation
Next step is selection of motor here we are using dc motor with gears to reduce speed and increase torque of motor . For installation of motor make a square like hole in the base of car tray table such that half motor fits inside that space or such that motor do not touch the top of table when fully closed.

Now attach motor to the base by drilling holes in the slot and then rotate a metal or plastic strip around motor and insert pins between metal strips and base so that motor can rotate .

Then attach a rod with threads to the shaft of motor .

Its time to insert  connect motor and system. to do so take a metal square of size just to fit two rods inside at each side drill two holes like one at left to right at the top edge of side and the other from front to back at the lower edge . make threads in one hole so rod attach to motor can rotate inside 

All parts will be connected as given in image .
final form of car tray table
Now attach two click switches to the base of car tray table to read position of table top.
As shown
switches are installed in upper right corner
Final form of car tray table will look like this
design of car backseat lunch table
final results
This will be final form of car table tray system ,
Next post is about schematic .

Car backseat table

By
Having your lunch or a light meal while you are travelling is a trouble for every one. Some of luxurious cars are now including tables for passengers on backseats. One approach to have this facility is to design your own using simple steps and parts 1st of all you need to make table top for which you can use kitchen cutting board as table top or you can machine your own . Modify it upto your requirements like cup holding place etc Next you have to plan attachement to the seats. It depends on the type of seats you have. Here i can write some of possibillities like if car seats have cloth on back then you have to open cover and attach rods horizontally to the frame of seat and if seats came with plastic on back then system's base could be attached with screws directly. base will also provide mechanichal support. Next step is to dicide about working of system. Some of options are Manual. Single table operating with button. Centralized system controlled by one keypad or remote

Car Backseat Table System using PIC Micro-controller

Before installing micro controller to operate car backseat table read previous posts about how to install mechanical parts, installing dc motor and position sensors First of all select any  micro-controller   which is available and have external interrupts. I am using PIC-16f1789 in car backseat tray table Identify signals to operate the system To operate Car back seat table using micro-controller we need 3 signals for each table. One signal from open and close command to each table Detect open position of each table Detect close position of each table Here we are operating two tables so we need total six signals which are connected to port A through current limiting resistors(value of which depends on device type, specified on datasheet of I.C. you  are using). Electrical specifications for PIC 16f1789 Port A is used for interrupt input.Connections will be as follows. port A,1 connect with open/close button for table 1. port A,2 connect with open/close button

Controlling servo with pic16f1789 for car backseat table

By
This post is about use of servo motor in Car backseat tray system.  Servo motor :                                     Servo motor is a dc motor with a derive circuit and position sensor for precise movements. position sensor used in servo motor is normally potentiometer attached to gears of motor. Derive circuit typically consists of  pulse width modulation to voltage converter feedback from potentiometer supply voltages Feedback from position sensor is compared with converted voltage and resulted output is used to correct position of motor until both signals are equal. Servo motor will maintain its position and resist  to any external change as long as modulated pulse is present at control wire of motor. Control signal :                               control signal is most complex signal out of three signal required to operate DC Servo motor . Other two signals are 0 v and 5 volts out of battery. To generate control signal we are using Pic 16f1789 micro-controller
