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 utility vehicle includes a door. The door includes an inner door panel disposed close to a cabin, and an outer door panel attached to an outer end of the inner door panel. The outer door panel is attached to an outer end of an upper portion of the inner door panel to expose a lower portion of the inner door panel when viewed from outside the vehicle.

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 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.

An exterior panel structure for a vehicle prevents unevenness caused by distortion of an outer surface of the exterior panel and keeps dents small even when a user presses the exterior panel from the outside. The exterior panel structure includes the exterior panel, and a reinforcing member having joint sections and coupling sections. The joint sections are separated from each other along an inner surface of the exterior panel, and each is joined to the inner surface of the exterior panel. The coupling section follows the inner surface of the exterior panel and couples the adjacent joint sections. The inner surface of the exterior panel and the coupling section abut each other when a pressing force equal to or larger than a specified value is applied inward in a thickness direction of the exterior panel from an outer surface of the exterior panel, and are otherwise separated from each other.

An exterior panel structure for a vehicle prevents unevenness of an outer surface of an exterior panel material caused by joining of a reinforcing member to the exterior panel. The reinforcing member is joined to the exterior panel material such that rigidity is maintained, thereby keeping dents in the exterior panel material small even when a user presses on the exterior panel material during waxing of the vehicle, or the like. The exterior panel structure includes a door outer panel, a reinforcing member, and a bracket. In the bracket, a joint surface which follows an inner surface of the door outer panel is joined to an outer peripheral edge of the door panel which is separated from the inner surface of the door outer panel in a thickness direction of the door outer panel, and another joint surface is joined to a reinforcing outer peripheral edge of the reinforcing member.

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 panel fastening structure of the panel door for a vehicle to which circumferences of an external panel and an internal panel are coupled, wherein a first side of the door hinged to a vehicle body includes the external panel and the internal panel fastened by a fastening member, and a second side of the door includes the external panel and the internal panel slidably coupled to each other.

A handle base bracket has a first handle receiving section and a fastener opening that extends through the first handle receiving section. In a fully assembled state the outboard surface of the handle base bracket overlays a portion of an inboard surface of a door panel. A first fastener member extends through the first handle opening and into the fastener opening. A head portion overlays a portion of the outboard surface of the door panel adjacent to the first handle opening. A metallic bracket has a main section fixedly attached to the handle base bracket. First and second side flanges of the metallic bracket extend toward the inboard surface of the door panel. An operation handle has a grip portion outboard of the door panel and a protrusion extending into the first handle receiving section of the handle base bracket.

A door bodyshell of a framed door of a motor vehicle is provided. The door bodyshell includes a door inside panel and an assembly fastened to the door inside panel. The door inside panel has an inner sill region and a peripheral frame structure, which is connected to the inner sill region, for a motor vehicle side window. The assembly fastened to the door inside panel has a reinforcing structure, which is arranged level with the inner sill region, and a door outside skin, which is connected to the reinforcing structure level with the inner sill region by way of a flange or a welded joint. In a state in which the door body shell is installed on the motor vehicle, the reinforcing structure level with the inner sill region is inclined in the direction of a motor vehicle interior such that the flange or the welded joint and a horizontal plane enclose an angle of less than 90. In the state in which the door body shell is installed on the motor vehicle, the flange or the welded joint is formed as far as at least an outer comer, in the longitudinal direction of the motor vehicle, of an outer sill region of the door body shell.
