Design of backdoor
Aim :
To develop the car Backdoor(Tail gate) with the reference of given skin data as per engineering standared by using NX12
Back Door :
The Back door is typically hinged, but sometimes attached by other mechanisms such as tracks, in front of an opening which is used for entering and exiting a vehicle.
A vehicle door can be opened to provide access to the opening, or closed to secure it. These doors can be opened manually, or powered electronically. Powered doors are usually found on minivans, high end cars, or modified cars.
Types of Back Door :
- Top Mounted
- Side Mounted
- Bootom Mounted
Top Mounted Back Doors :
Side Mounted Back Door :
Bottom Mounted Back Door :
Design Consideration :
- Visibility Criteria
- Latch and Stricker Position
- Hing Position
- Gas Stay Position
- Space Avalibility
- Drain Holes
- Hemming and Relief area's
Components of Back Door :
The Components of Back Door as follows,
- Inner Panel
- Outer Panel
- Hing Reinforcement
- Latch and Stricker Reinforcement
- Gas stay Reinforcement
- Wiper motor Reinforcement
Inner Panel :
Hinge Reinforcement :
Hinges are the essential, that allows doors to pivot on one edge as they open and close. They are found on virtually all doors. It is a mechanical bearing that connects two solid objects, typically allowing only a limited angle of rotation between them.
Gas stay Reinforcement :
It is used to lift up the Tail gate.
There are two types of Gas stay reinforcement is there. That they are
- Manual System
- Power Lift System
Manual System :
This mechanism is most used in Indian cars. It is operated man by his own.
Power Lift System :
It works on the basics of Sensor.
Latch Reinforcement :
A latch is not the same as the locking mechanism of a door or window, although often they are found together in the same product. Latches range in complexity from flexible one-piece flat springs of metal or plastic, such as are used to keep blow molded plastic power tool cases closed, to multi-point cammed latches used to keep large doors closed.
Wiber moter Reinforcement :
It is small electric motor which is mounted in the rear Tail gate. It used to clean the rear wind sheid for clear visiability.
Outer Panel :
Force Distribustion :
When the car hited at rear end, the force which acted should be react outside. The Y emboss which is helps to move the force to the outer end.
Corner Relief:
Relief helps to control sheet metal material behavior and to prevent unwanted deformation during unbend operations. So here i gave two cornor relief for Back door.
Hemming :
