A cabin-interior upright wall of a door inner panel is configured by a first panel member alone. An extension wall extends toward a door outer panel from an end of the cabin-interior upright wall. A lower portion of a front upright wall, which is part of the extension wall, is segmented in a door thickness direction. The extension wall is configured such that a first extension portion of a first panel member is joined to a second extension portion of a second panel member in a state overlapped with the second extension portion.

A carrier module for a motor vehicle door assembly having inner and outer panels defining a door panel structure with the inner panel having an opening for selective access to an internal door cavity between the inner and outer panels is provided. The carrier including an outer periphery configured for attachment to the inner panel to substantially close off the opening, and at least one reinforcement member fixed to the carrier, the at least one reinforcement member being formed of a material having a resistance to loading that is greater than a resistance to loading of a material of the carrier.

A vehicle panel assembly for a motor vehicle includes a structural door panel body having an inner door panel and an outer door panel defining an internal cavity. A carrier module is secured to the structural door panel body. The carrier module has a carrier having an outer periphery for attachment to the inner door panel to substantially close off an opening therein to separate a wet side of the door panel body from a dry side of the door panel body and having a recessed pocket configured for receipt of a rear side of a speaker therein to maintain the speaker on the dry side of the door panel body. At least one of a barrier and shroud is coupled to the carrier. The barrier forms an air pocket with the carrier on a side of the carrier facing the wet side of the structural door panel body.

A vehicle having an exoskeleton exterior panel that provides crash resistance is described. The exterior panel may be formed from a monolithic metal sheet and attached to an exterior portion of the vehicle frame, and the exterior panel does not comprise an additional support structure. At least one component may be directly attached to the exterior panel, and the exterior panel may bear the load of the at least one component. Methods of manufacturing the vehicle are also described.

A panel door applied for a vehicle including a stiffness member made of a plastic material and integrally formed on an internal surface of the panel door, includes an external panel, an internal panel coupled to the external panel, and a stiffness member formed to connect a frame forming a circumference and stiffness elements provided for reinforcing stiffness inside the frame and coupled to at least one of the external panel and the internal panel.

A vehicle having an exoskeleton exterior panel that provides crash resistance is described.

A vehicle door assembly includes inner and outer door panels, first and second support brackets, a reinforcing panel, a window opening support panel and a side mirror assembly. The first support bracket is attached to the inner door panel. The reinforcing panel is attached to the first support bracket. The second support panel attached to the first support panel and the reinforcing panel. The window opening support panel is attached to the inner door panel, the second support panel and the reinforcing panel. The outer door panel is fixed to the inner door panel such that the inner door panel and the outer door panel define a door cavity therebetween. The side mirror assembly is installed along an exterior side of the outer door panel. The side mirror assembly includes fasteners that extend through the window opening support panel and the second support panel.

A shock absorbing structure of a vehicle door including a vehicle body panel with a service hole includes a door trim and a shock absorber. The door trim covers the vehicle body panel from an interior side of a vehicle. The shock absorber is mounted to the vehicle body panel to cover the service hole. The shock absorber includes a shock absorbing portion that is inserted in the service hole. The shock absorbing portion is disposed such that an end of the shock absorbing portion on an exterior side of the vehicle is disposed more to the exterior side of the vehicle than the service hole and between the vehicle body panel and the door trim.

A vehicle door structure includes an outer door panel made of resin, etc. The outer door panel has an attenuated portion. The attenuated portion is provided along a boundary line that divides the outer door panel into at least a first region that includes the outer door handle and other regions.

A door of a vehicle may include a first door module forming a door skeleton; a second door module coupled with the first door module and forming a door window; and a door frame coupled to the first door module and engaged with the second door module; wherein the second door module may include a relatively lightweight material as compared to the first door module, reducing weight and cost of the door for a vehicle.
