When it comes to travelling by cars, mishaps and unwanted incidents such as tyre puncture, low air pressure in tyre are extremely common. A conventional carjacking system makes use of mechanical advantage to lift the cars. Despite the mechanical advantage jacking up a car is a very difficult task for many people especially women and elderly people. The objective of this project is develop a new carjacking system in order to make the operation easier, safer and more reliable in order to save individuals from unnecessary expenditure of energy and reduce health risks especially backache problems. In the context of this particular project, the newly developed scissor jack uses a 12 V DC motor as the prime mover which works using the car battery. The motor is connected to the lead screw of the jack through reduction gear, so as the motor starts, the pinion is rotates with a torque equal to the motor torque. Since the pinion is in mesh with the gear (double the number of teeths in pinion) in the lead screw, the driven gear starts rotating with a multiplied torque, thereby lifting the car. The developed system also has a provision for inflating the tyre, which is used when the air pressure in the tyre is lesser than ideal conditions. The system uses a reciprocating type compressor which works on the 12 V supply. The main advantage of this system is that we can use it whenever we requires.
