Disclosed is a structure for a hybrid-type door, which is capable of preventing deformation caused by difference in thermal expansion coefficient between an outer panel of aluminum alloy and an inner panel of iron steel. The structure for a hybrid-type door may include an inner panel and an outer panel made of different material from the inner panel. In particular, an end portion of the inner panel may be hemmed by an end portion of the outer panel with the end portions of the inner panel and the outer panel being brought into contact with each other. A sealer may be applied to a contact area at which the inner panel and the outer panel are brought into contact with each other, and the sealer may include a first sealer that may be curable at a room temperature, and a second sealer that may be curable at a temperature greater than a curing temperature of the first sealer.

A hemming structure may include a door, in which the door has an internal panel and an external panel made of different materials, the hemming structure being configured such that each of the internal panel and the external panel is provided with a contact area with end portions of the internal panel and the external panel contacting with each other at the contact area, wherein the contact area includes a first contact area with a sealer applied onto a contact surface between the internal panel and the external panel, and a second contact area extending from the first contact area and being bent to be brought into contact with the internal panel at the first contact area, and the second contact area is provided with a bonding portion at which the internal panel and the external panel are mechanically bonded to each other.

A composite sheet metal component for an automobile comprises an inner metal sheet, an outer metal sheet and an intermediate polymer sheet arranged between the inner and the outer metal sheet. The intermediate polymer sheet comprises a semiconductor device and the outer metal sheet comprises at least one functional area.

A door structure for a vehicle may include an external panel that forms an external side surface of the vehicle; a reinforcement beam that is engaged with the external panel; an internal panel of a reinforced plastic material that is engaged with the reinforcement beam; and a fastener that fixes the internal panel and the reinforcement beam.

A door structure for a vehicle may include an external panel; an internal panel that is mounted to the external panel; and an impact member coupled to the internal panel between the external panel and the internal panel, wherein a protrusion that protrudes to an outside thereof toward a side external panel of a vehicle body from inside the internal panel is integrally provided in the impact member.

The invention relates to an opening part of a motor vehicle comprising a reinforcing element extending at least partially along a main plane, intended to reinforce fasteners and the environment of a lock of the opening part, and an envelope made from plastic, comprising an inner part overmolded at least partially on an inner face of the reinforcing element. The reinforcing element comprises at least one orifice, and the envelope comprises at least one external part including a segment passing through said orifice and a covering part locally covering one edge of the orifice on an outer face of the reinforcing element.

A vehicle body structure includes a reinforcing material layer formed of a fiber reinforced resin and a vehicle skeleton member having a closed sectional structure formed of metal. The reinforcing material layer is bonded to a surface of the vehicle skeleton member having a recessed portion recessed toward an inside of the closed sectional structure. An adhesive is disposed at least between the recessed portion and the reinforcing material layer.

An add-on part (1) of a vehicle body, such as a door (1) or tailgate, has interconnected inner and outer parts (2, 4) and reinforced portions (5, 6) and a reinforcing device (7) connecting said reinforced portions (5, 6). The reinforcing device (7) has arms (8, 9, 18, 19), and, in the region of the ends of the arms (8, 9, 18, 19), the reinforcing device (7) is connected in a force-fitting and/or form-fitting manner to the reinforced portions (5, 6). Such an add-on part, while having a structurally simple design and relatively low weight, ensures particularly good stiffening properties.

This panel structure for an automobile (10) includes: an outer panel member (1) having a sheet shape; a resin member (2) that is disposed on an inner surface of the outer panel member (1); and an adhesive portion (3) that bonds the outer panel member (1) and the resin member (2), in which the outer panel member (1) includes a base metal (12) and a coating film (14) provided on the base metal (12), the base metal (12) has a sheet thickness of 0.3 mm to 0.5 mm, the resin member (2) has a bending rigidity of 0.3?10.sup.6 N.Math.mm.sup.2 or more, and the adhesive portion (3) contains a cured material of a room-temperature curing adhesive.
