A door outer panel including a top edge; A door inner panel coupled to the door outer panel; An outer belt rail fitted and coupled to the upper edge; And an outboard belt molding coupled to the outer belt rail; The assembly work of the outer belt rail and the outer belt molding becomes easy.
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door structure for an automobile, and more particularly, to a door outer panel made of plastic material or CFRP (Carbon Fiber Reinforced Plastics) To a door structure.
Generally, the automotive door has a structure in which a door outer panel positioned on the outer side along the width direction of the vehicle and a door inner panel located on the inner side are coupled to each other, and the door outer panel and the door inner panel are made of steel panels A panel door joined to each other, and a frame door reinforced with the panel door.
In recent years, in order to reduce the weight of the vehicle and to improve fuel economy, it is also made of materials other than steel, such as plastic or CFRP.
The automobile door manufactured as described above is provided with a window for ventilating the interior of the vehicle, and a door glass is installed on the door for the automobile to open and close the window.
At the periphery of the window, an outward belt molding and an inner belt molding, which are in close contact with the window glass, are mounted on the door outer panel and the door inner panel, respectively, in order to maintain airtightness while the window glass is closed.
An outer belt rail is mounted on the door outer panel to guide rigidity reinforcement and smooth upward and downward movement of the window glass and an outer side belt molding is mounted on a junction between the outer belt rail and the door outer panel.
In the conventional door structure for an automobile as described above, in the case of a steel door or a frame door, a hemming process for joining between a door outer panel and an outward belt rail is required, Since the side belt molding is mounted via a clip or the like, the assembling property is not good. When the window glass is lifted and lowered due to the assembly failure, the outward belt molding may receive external force by the window glass.
An embodiment of the present invention is to provide an automotive door structure capable of easily assembling an outer belt rail and an outer side belt molding to a door outer panel made of plastic material or CFRP, and reducing weight and cost.
An automotive door structure according to an embodiment of the present invention includes: a door outer panel including an upper edge; A door inner panel coupled to the door outer panel; An outer belt rail fitted and coupled to the upper edge; And an outer side belt molding coupled to the outer belt rail.
The door outer panel may be made of plastic material or CFRP.
The outer belt rail includes a head portion having a triangular shape; And a leg portion extending integrally downward from the head portion along the height direction of the vehicle.
The head portion includes a first assembling groove in the form of being worn outwardly from the inside in the width direction of the vehicle; And the outer side belt molding is inserted into the first assembly groove.
Wherein the leg portion extends downward in the height direction of the vehicle from the head portion and then is bent backward outward in the vehicle width direction, and a second assembly groove is formed between the head portion and the leg portion; And the upper edge may be inserted into the second assembly groove.
The outer side belt molding comprises: a molding body formed to extend in the height direction of the vehicle; And first, second, and third sealing lips extending inward from the molding body in the width direction of the vehicle.
Wherein the outer side belt molding comprises a molding body formed to extend in the height direction of the vehicle; Wherein the molding body is formed with a fitting protrusion extending outward in the width direction of the vehicle; And the fitting projection may be inserted into the first assembly groove and engaged with the first assembly groove.
The molding body may be formed with an extension extending in the height direction of the vehicle from below the fitting protrusion to the outside in the vehicle width direction.
The reinforcing member may be inserted from the distal end of the fitting projection to the extending portion via the molding body.
Wherein at least one concave groove is formed in the first assembly groove; The fitting protrusion may be formed with one or more protrusions inserted into the concave groove.
At least one concave groove is formed in the leg portion; The extended portion may be formed with one or more protrusions inserted and coupled to the at least one recessed groove.
The outer belt rail includes: a head portion formed to extend in a width direction of the vehicle; A first extension extending from the head portion downward in the vehicle height direction; A second extension extending outwardly in the width direction of the vehicle from the first extension; And a leg portion extending downward from the second extending portion in the height direction of the vehicle.
An assembling groove formed by the head portion, the first extending portion, and the second extending portion is opened outward in the width direction of the vehicle; And the upper edge may be inserted into the mounting groove.
The outer side belt molding comprises: a molding body formed to extend in the height direction of the vehicle; And a first, second, and third sealing lip extending obliquely upward from the molding body in a width direction of the vehicle and a height direction of the vehicle.
Wherein the molding body is formed with first and second fitting protrusions extending outward in the width direction of the vehicle; The outer belt rail may be formed with two fitting grooves through which the first and second fitting protrusions are fitted.
Wherein the outer belt rail is formed with at least one concave groove; The outer side belt molding may be formed with at least one fit-in protrusion that is fitted to the at least one concave groove.
The outer belt rail includes: a head portion formed to extend in a width direction of the vehicle; A first extension extending from the head portion downward in the vehicle height direction; A second extension extending outwardly in the width direction of the vehicle from the first extension; And a leg portion extending from the second extension portion downward in the vehicle height direction; The outer side belt molding comprises: a molding body formed to extend in the height direction of the vehicle; First, second, and third sealing lips extending obliquely upward from the molding body in a vehicle width direction and a vehicle height direction; And an extension extending outwardly in the width direction of the vehicle and in close contact with the second extension of the outer belt rail.
The outer belt rail and the outer side belt molding may be integrally injection molded.
According to the door structure for an automobile according to the embodiment of the present invention, since it is not necessary to use the conventional door out side belt rail, it is possible to reduce the weight of the door for an automobile, the number of assembling steps and cost.
In addition, since there is no need to weld the outer outboard panel and the outer belt rail together, it is possible to reduce the number of workings, and the assembly direction of the outer side belt molding is changed to facilitate assembly, It is possible to prevent the occurrence of the joint.
In addition, the height of the outer side belt molding is lower than that of the conventional art, thereby improving the design freedom.
