Disclosed is a method for manufacturing a light-reflection aluminum door frame molding which comprises a multi-coating-applied aluminum material to thereby improve corrosion resistance and reduce costs. A method for manufacturing a light-reflection aluminum door frame molding includes cutting a metallic plate into a predetermined size, performing anodizing on the metallic plate to form an oxidized film on a surface thereof, performing opaque clear coating and transparent coating on the metallic plate to implement light reflection, and performing press molding on the metallic plate to provide the metallic plate in the shape of a door frame molding.

An inner door panel (30) for a vehicle side door that includes an integrated side impact beam (70) formed as part of the door in a die casting process. The inner door panel (30) includes an outer frame having a top rail (38), a bottom rail (40), an inner side rail (42) and an outer side rail (44) defining a central opening (34). The impact beam (70) includes a main beam portion (72), a first end support portion (74) and a second end support portion (78). The first end support portion is formed to the side rail (42) and the second end support portion (78) is formed to the outer side rail (44), where the main beam portion (72) extends across the opening (34).

A method of laser welding a first aluminum workpiece and a second aluminum workpiece arranged to form a lap joint includes forming a laser weld between the first aluminum workpiece and the second aluminum workpiece and forming a lap through weld joint using a weld speed equal to or greater than 10 meters per minute. The laser weld has less than 10% area fraction keyhole voids, for example, less than 5% area fraction keyhole voids and the lap through weld joint can have a flange length of less than 10 mm. The first aluminum workpiece can be an inner workpiece of a halo assembly of a vehicle door, the second aluminum workpiece can be a channel workpiece of the halo assembly and laser welding the inner workpiece to the channel workpiece forms the halo assembly without the use of mechanical fasteners, thereby decreasing weight and costs of the halo assembly.

There are provided an outer member, an inner member including a front-side vertical wall portion and a rear-side vertical wall portion, an impact bar extending from front-side attachment portions of the front-side vertical wall portion to rear-side attachment portions of the rear-side vertical wall portion, a hinge-reinforcement member reinforcing a hinge attachment portion where a hinge is attached to the front-side vertical wall portion, and a latch-reinforcement member reinforcing a latch-attachment portion where a latch device is attached to the rear-side vertical wall portion. The front-side vertical wall portion and the rear-side vertical wall portion are made of casting or high-strength resin, and the hinge-reinforcement member and the latch-reinforcement member are configured to have higher ductility than the front-side vertical wall portion and the rear-side vertical wall portion and connected to the impact bar.

An Al-steel assembly is provided. The assembly includes an aluminum-based element and a steel element on at least one surface of the aluminum-based element. The steel element has a metal coating made of a zinc-aluminum-magnesium alloy and includes from 2.3% to 3.3% by weight of magnesium and from 3.6% to 3.9% by weight of aluminum. A coated surface of the steel element is in contact with the aluminum-based element in an assembly zone and a protective coating coats the assembly around and adjacent the assembly zone. A body-in-white, further assembly and method are also provided.

A vehicle door assembly includes an outer panel and an inner panel. The outer panel has an inboard surface and an outboard surface. A door handle receiving area is disposed in the outer door panel and is configured to receive a door handle. The inner panel has an inboard surface and an outboard surface. The inner panel is connected to the outer panel. A first stiffener member is disposed beneath the door handle receiving area. A second stiffener member is disposed above the door handle receiving area.

A side door assembly is provided for an automotive vehicle body having a side opening. The side door assembly includes a front casting for hinged connection to the vehicle body. A rear casting is also provided for latch connection of the vehicle door assembly to the vehicle. An extrusion and/or extrusions connect the front and rear castings providing a side door assembly that is extremely light, enhancing the ability of the driver to enjoy the vehicle.

The present invention relates to refrigerated trucks, more particularly to a refrigerated truck with side doors, including a refrigerated compartment, a chiller, a partition plate, glass plates, top plates, rotating shafts, side doors, support plates, air curtains, floors, base plates, slots, recessed handles, rails, moveable windows, moving handles and grooves. In the refrigerated truck with side doors of the present invention, doors are arranged on both sides of the refrigerated compartment, and the air curtains are used, which effectively reduces the amount of cold air loss and hot air intrusion, thereby reducing energy consumption of the chiller. Moreover, the support plates are configured to play an auxiliary role in both bearing load and keeping the balance. The present invention makes a contribution to energy saving of the refrigerated truck.

A press forming apparatus that produces a character line in a design surface of an outer panel by press forming includes an upper die and a lower die. The upper die has a die surface that is configured to form a design surface of an outer panel. The lower die has a die surface corresponding to the die surface of the upper die. The die surface of the lower die has, in a formation area of the character line, a curved convex portion that protrudes beyond an offset line of the die surface of the upper die and curved concave portions continuous with the curved convex portion. Each of the curved concave portions is on a corresponding one of both sides of the convex portion and is recessed beyond the offset line.

A door of recreational vehicles includes a first peripheral frame, a first outer panel, shaped to match the first peripheral frame and positioned inside the first peripheral frame, with the first outer panel extending according to a predetermined plane (P), and a second inner covering panel substantially superposed on the first outer panel.
