Design of backdoor

Aim: BackDoor Design

Objective: To design backdoor panels using NX CAD.

Design Methodology:

Description:

Car Backdoor which is the enclosure of the car rear side consists of an Inner Panel, outer panel, and some of the mountings like gas stay, hinge, latch and striker, and wiper motor mechanism. Car backdoor parts are made either made of Aluminium or Steel. But aluminium is a bit costlier than steel. But using aluminium weight will be reduced.

Tooling direction:

Tooling direction is the direction along which the tool is pressed to the sheet in order to get the desired shape.

Inner Panel:

Outer Panel:

Outer Panel consists of Upper and Lower Panel which are done seperately.

Hinge Reinforcement:

A hinge is provided in order to make a connection with the rooftop and the back door. The hinge axis is considered for the placement of hinges so that door is lifted up and down properly without any misalignment. Reinforcements are provided in order to increase the strength of the hinge.

Gas Stay Reinforcement:

Gas stay is a hydraulic cylinder that helps to move the door up and down.

There are different types of gas stay arrangements in different vehicles based on their design.

Wiper Motor Reinforcement:

The door glass wiper motor is placed at the defined position so that to wipe the glass during the rainy season so that the driver can see the vehicles coming behind them.

Latch & Striker Reinforcement:

Latch and striker is placed at the designated place so that they meet and the door is locked perfectly without any gaps.

Trajectory for Latch and Striker:

It is the path along which the back door is moved and up and down so that the latch meets the striker exactly and the door is placed properly.

Back Door Assembly:

Conclusion:

Car Backdoor is designed using NX CAD.
