Description
Technical Field
[0001] The utility model belongs to the technical field of automobile parts, and in particular relates to a mounting structure for matching a vehicle body fender sheet metal and a bumper skin. Background Art
[0002] When assembling the bumper skin, a gap of 0.5mm-1.0mm should be left between the bumper skin and the body fender sheet metal. At present, the body fender sheet metal and the bumper skin are mainly limited by the support ribs 1 set on the bumper skin (see Figure 1 ), the support rib 1 is limited by the appearance gap and the bumper skin injection mold, and can usually only be hidden 2mm-3mm inside, which causes the rounded corners of the body fender sheet metal to easily cause bumps and paint peeling when assembling the bumper skin, and the product has the risk of rust. Therefore, it is necessary to provide a new installation structure that can not only ensure the gap between the body fender sheet metal and the bumper skin, but also prevent the body fender sheet metal from bumping and paint peeling during assembly.

The bumper skin is limited by the elastic supporting sheet and is not restricted by an exterior gap and an injection mold, and can be hidden 5 mm inward, thereby avoiding the risk of paint scratching at a rounded corner of a vehicle body fender sheet metal exterior surface.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A mounting structure for matching a vehicle body fender sheet metal and a bumper skin, comprising a bumper skin bracket body, wherein the bumper skin bracket body is provided with an elastic support sheet inclined toward the vehicle body fender sheet metal side at a rounded corner of the exterior surface of the vehicle body fender sheet metal, the bumper skin is arranged on the inner side of the elastic support sheet, and the bumper skin is provided with a concave assembly groove at a position opposite to the elastic support sheet, the depth of the assembly groove is less than the thickness of the elastic support sheet, the elastic support sheet is arranged in the assembly groove, the elastic support sheet is an L-shaped structure, comprising a connecting part and an elastic limiting part, the connecting part is connected to the bumper skin bracket body, the elastic limiting part is inclined on the connecting part toward the vehicle body fender sheet metal side, the elastic limiting part is a variable diameter structure, comprising an elastic limiting body and an elastic limiting contact, the thickness of the elastic limiting contact is greater than the thickness of the elastic limiting body, and the top surface of the elastic limiting contact contacts with the vehicle body fender sheet metal.
[0006] As a preferred embodiment of the present invention, the elastic supporting sheet and the bumper skin support body are an integral injection molding structure.
[0007] The utility model has the following advantages and positive effects:
[0008] (1) The installation structure provided by the utility model improves the bumper skin bracket structure, and an elastic support sheet support structure is made on the bracket body. The elastic support sheet is used to limit the position. This installation form is not limited by the appearance gap and the injection mold, and can be hidden 5mm inward, avoiding the risk of paint scratching at the rounded corners of the body fender sheet metal appearance.
[0009] (2) The installation structure provided by the utility model is easier to assemble the bumper skin because the elastic support sheet on the bumper skin bracket is elastic. BRIEF DESCRIPTION OF THE DRAWINGS
