Doors DFMA

Manufacturing Plan

Hinges

Hinge Base and Arm

  • Initial sheet metal parts are cut by E3/supplier

  • Sheet metal parts are bent by supplier

  • Welded together at E3

Hinge-Door Panel Intermediate

  • 8 small components which need to be CNC machined

    • can use anything left in bay, otherwise sourced

Latch

  • Handles - 3D print components

  • Pushrods - Laser cut from scrap/excess sheet metal from hinges

    • Pushrod mounts for stability? - 3D printed

  • Wire Routing Rods - 3D print

 

Assembly Plan

Hinges

  • Use clevis pin to combine hinge arm and base

  • Use leftover Dynamics fasteners for combining intermediate w/ hinge and mounting on chassis

Latch

  • Latch mount and handle mount to be attached to car door using adhesive

  • Handles are assembled with torsion spring and pin

  • Pushrods are connected using dynamics fasteners, and potentially mounted for stability

  • Wires are routed using rods through interior panel - need to ensure there are cutouts/space

    • Only on front door, back door only uses pushrods
