Motorized Scissor Jack

Aim:

            The main stay of the project is to design, mechanize and fabrication of motorized scissor jack using piezoelectric sensors and invertors.

Proposed System:

            Here we are going to create a motorized scissor jack powered using the mobile charging port available in the car. A motor is fitted to the scissor jack to lift and lower the scissor jack, a simple controller is installed to the motor control the lifting and lowering of the scissor jack.

Advantages:

1.                Portable: This jack can be easily portable due to its small footprint. They are small enough to be fitted in the trunk, which is why you would love to keep one to stick in your spare tire.

2.                  Lightweight:  Another advantage that it has over hydraulic jack is that it is very lightweight in nature. This makes it very handy as you can easily carry it and place it under your car even in pinch moments like having to replace the flat tire with a spare while being on side of the road.

Abstract :

            A Scissor Jack is a mechanical device used to easily lift a vehicle off the ground to gain access to sections underneath the vehicles or to change the wheel. The most important fact of a jack is that it gives the user a mechanical advantage by changing the rotational force on power screw into linear motion, allowing user to lift a heavy car to the required height. It is called a scissor jack as the structure consists of diagonal metal components that expand and contract in the same way as a pair of scissors. In this work a power scissor jack to lift and support a load of 4.5KN for typical use in four wheelers has been designed and fabricated by selecting the most appropriate materials and cross sections. The dimensions of various components are standardized for easy assembly and replacement, if required. The overall cost of the jack is relatively less compared to commercially available screw jacks. The self-weight of the power jack is minimized for easy handling.
