Design of backdoor
AIM:
Objective of this project is to create the whole inner panel with some design considerations.
intoduction:
A car door is a type of door opening, typically hinged on its front edge, but sometimes attached by other mechanisms such as tracks, for entering and exiting a vehicle. Doors most often integrate side windows for visibility from inside the car and can be locked to secure the vehicle.
Car doors may be manually operated or with power assist supplied by the vehicle. Powered doors or power doors may be found on minivans, luxury vehicles, or modified cars.
Types of doors based on working position:
1.top mounted door.
2.side mounted door.
3.bottom mounted door.
The backdoor is opened by 2types of comodities:
1.electrically operated.
2.gas stay.
Backdoor assembly:
1.inner panel.
2.outer panel.
3.wiper mounting reinforcement.
4.hinge reinforcement.
5.gas stay reinforcement.

BENCHMARK STUDY FOR MATERIAL:
INNER PANEL DESIGN:
while designing the tailgate inner panel we just consider gaps b/w outer panel,embossing, thickness and location for hindge,gas stay,wiper mount etc..
inner pannel thickness is0.75mm and we give a tolerance 0.2mm..
outer panel:
The outer panel is developed by the syting suface..
Through this panel we joint together with inner panel by hemming process
OUTER UPPER PANEL:
OUTER LOWER PANEL:
TAILGATE IMG
DRAFT ANALYSIS:
I USE DRAFT ANALYSIS FOR TO CHECK THE MANUFACTURE FEASIBILITY...
RESULT:
I successfully completed this project and had a hands on experience on surface tools...
