Abstract

The invention discloses a vehicle door sill system, which comprises a vehicle door inner sheet metal, a vehicle door outer sheet metal, a door sill rubber strip and an exterior decorative panel, the threshold rubber strip is connected with the vehicle door inner sheet metal, and the external decorative panel is connected to the vehicle door The outer sheet metal of the car door is connected, the outer sheet metal of the car door is connected with the inner sheet metal of the car door, and the buckle on the outer trim plate passes through the inner sheet metal of the car door and the outer sheet metal of the car door The door sill rubber strip is connected, and the lower boundary of the exterior trim panel is sealingly connected with the lower edge of the door sill rubber strip. The modeling freedom degree of the present invention is improved, and the door molding of the irregular threshold can be realized. By passing the fasteners through the door outer sheet metal and the door inner sheet metal, the arrangement of the fasteners can be closer to the front and bottom, which increases the connection strength of the exterior trim and achieves a shorter and deeper exterior trim structure . In addition, through the sealing connection between the lower boundary of the exterior trim panel and the lower edge of the door sill rubber strip, better fixing of the door sill rubber strip can be achieved, and at the same time, the full wrapping and sealing of the door sill can be realized.

Description

technical field

[0001] The invention relates to the technical field of vehicle doors, in particular to a vehicle door threshold system. Background technique

[0002] In the existing door sill system, the inner sheet metal of the door, the outer sheet metal of the door, and the door sill strip are the lower boundary of the straight line, which cannot fully match the curved boundary of the outer trim panel, forming a gap where sediment is easy to accumulate; and the height of the outer trim panel is relatively high. Large, small width, which limits the freedom of shape; there is not enough connecting space between the outer door trim and the metal sheet, and double-sided adhesive needs to be set for bonding, and the installation strength is poor, especially after a long time , easy to deform or even fall off; because the door sill rubber strip is only fixed by the upper buckle, the sealing and appearance effect is poor, it is easy to accumulate dust and sand, and the bottom is...
