In this work an automatic car cover is proposed which will opens itself with the help of push button. It covers the whole car with a thin, but a strong material that not only protects the car from rain, dust and mud (in parked situation) but, also from minor scratches. An assembly of different diameter, concentric cylinders is used to form a hoisting pole and also, so that it could be contained in small space when not in use. The cover material is attached to the top of the innermost cylinder on both sides and to a rolling rod, which has the cover rolled on it. For the accomplishment of our task we are using a simple but dependable mechanism of rack-and-pinion gears. A flexible rack is attached to innermost of the 4 concentric, different diameter hollow cylinders. The pinion is attached to a motor, which derives its power from the car battery. As the pinion moves, the rack moves and pushes the innermost cylinder upwards. The bottom of every inner cylinder is attached to the top of the just outer cylinder, but providing the linear motion between the two. When the rack moves, the innermost cylinder is pushed, which in turn, after being completely hoisted makes the second inner cylinder to move. The After second the third cylinder is hoisted and with it the complete four cylinder pole structure is formed. After complete hoisting, whole structure is rotated along the rear parallel axis of the car. The cover takes the shape of the car and the car is well protected. After complete hoisting, whole structure is rotated along the rear parallel axis of the car. The cover takes the shape of the car and the car is well protected. It is most suited for sports car, because sports car generally have open roof.

|difficult and messy task, we came up with the idea of an automated or self-dispensing car cover. The car cover would be simple, dependable, strong and affordable. Keeping this product cost effective is important because it must be able to compete in market when introduced. And, there should not be much difference between the cost of traditional covers and this one. Efforts are being made to even make it multi-purpose, since it could act as a bumper protector also, attached to the rear of the car. The basic objective behind creation of such a product is to simplify and automate the process of covering a car. This makes the process easy and much less tedious|

DETAILED DESCRIPTION OF MODEL PARTS
|The numbering has been done in the above diagram according to the sequence of the processes.|
|1. Pinion – The pinion of the whole mechanism is a small gear made of mild steel. It is driven by a motor at a very low rpm. The power for this motor is derived from the car battery itself. It is directly meshed with the rack.|
|2. Rack – A flexible rack is to be used so that it would be able to bend. This rack is attached to the bottom of the innermost cylinder of the pole assembly. 3. Innermost cylinder – This cylinder is of minimum diameter. It moves upwards with the movement of rack. With the help of a welded ring, at the bottom, this cylinder is attached to the just outer cylinder.|
|4. Second inner cylinder – The top of this cylinder, through a welded ring, is attached to the inner cylinder. Which facilitates the movement of this cylinder (upwards), after the innermost cylinder has been completely lifted.|
|5. Third inner cylinder – The top of this cylinder, through a welded ring, is attached to the second inner cylinder. Which facilitates the movement of this cylinder (upwards), after the second inner cylinder has been completely lifted.|
|6. Outermost cylinder – This is the cylinder with largest diameter. This is directly attached to the rotating mechanism and base.|
|7. Cover material – The material used for covering the car is an extremely strong canvas made up of a cross woven polyester and cotton blend. This canvas is immensely tough but cheap.|
|8. Turning or rotating mechanism – After complete hoisting, whole structure is rotated along the rear parallel axis of the car. This is done through another motor. The cover material takes the shape of the car and the car is well protected.|
WORKING OF MODEL
|When the motor (1) starts with help of remote it releases the concentric cylinders (6,5,4,3 resp.) with the help of pretension spring inside each cylinders. The rope connected by motor and passes through pulley (2) gives the motion in longitudinal direction. When the concentric cylinder fully opens, whole rotation mechanism which is connected outer most cylinder and this mechanism connected by rod (10) to be fixed with chassis via RC motor gives the motion in transverse direction. The ends of innermost cylinders are joined by cover material (7), which covers the car fully. To unwind the cover simply push the remote button to work the motor in opposite direction. This is a simple and fully automatic light weight and low cost mechanism to cover the car. Because of its less weight it doesn’t affects the mileage of car.|
