Description
Technical Field
[0001] The utility model belongs to the technical field of automobile manufacturing, and in particular relates to a thin-wall hinge installation structure of a back-mounted rear anti-collision plate and a lower skin of a bumper. Background Art
[0002] In the prior art, rear bumper plates are mostly assembled to the lower skin of the rear bumper from the front. Such a design defines a relatively simple assembly relationship, but has high requirements on the position of the styling design seam and the angle of the styling surface flange, and has poor freedom in the surface design. The OEMs often have to make concessions in the styling design due to the requirements of the styling structure flange. In addition, the clamping structure between the rear bumper plate and the side flange of the lower skin will also increase the complexity of the mold structure at this location, resulting in high mold processing costs. Conventional back-mounted rear bumper plates have to solve the assembly envelope interference problem between the flange of the bumper plate extension and the flange of the lower skin. For details, please refer to Figure 1 , it is often necessary to make design concessions on the position of the styling seam or remove the flange between the lower skin and the wheel arch, sacrificing the appearance matching quality of the lower skin and the wheel arch. Utility Model Content
[0003] In view of the above problems, the purpose of the utility model is to provide a thin-walled hinge installation structure for a back-mounted rear bumper and a lower bumper skin. The bumper is back-mounted, the upper end of the bumper is connected by evenly distributed buckles, and the side of the bumper is fixed by a thin-walled hinge structure with fasteners. This solution allows a higher degree of freedom in the design of the styling surface split, solves the pain points of the traditional back-mounted solution, simplifies the side product installation structure, and simplifies the side mold structure, so as to overcome the shortcomings of the above-mentioned prior art.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A thin-wall hinge mounting structure for a back-mounted rear bumper plate and a lower skin of the bumper, comprising: a rear bumper plate and a lower skin of the rear bumper connected to the rear bumper plate, characterized in that bendable connecting pieces are integrally formed on both sides of the rear bumper plate, a plurality of buckles are evenly distributed on the upper end of the rear bumper plate, the bendable connecting piece is fixedly connected to the lower skin of the rear bumper by rivets, the bendable connecting piece is used for adjusting the folding angle between the rear bumper plate and the lower skin of the rear bumper during assembly, and the upper end of the rear bumper plate is fixedly connected to the lower skin of the rear bumper by a buckle.
[0006] As a preferred embodiment of the present invention, the bendable connecting piece includes: a bending portion connected to the rear anti-collision plate, and a fixing portion connected to the lower skin of the rear bumper.
[0007] As a preferred embodiment of the present invention, a plurality of rivet holes are provided on the fixing portion, and the pull rivets are installed at positions corresponding to the rivet holes on the lower skin of the rear bumper.
[0008] The advantages and positive effects of the utility model are: the rear bumper plate of the utility model is back-mounted, the upper end of the rear bumper plate is connected by a buckle, and the side of the bumper plate adopts a bendable connecting piece (thin-wall hinge) structure with fasteners for fixing. This makes the design freedom of the styling surface split higher, solves the interference pain point of the traditional back-mounted solution, simplifies the side product installation structure, and simplifies the side mold structure.

[0019] In the following description, for the purpose of illustration, in order to provide a comprehensive understanding of one or more embodiments, many specific details are set forth. However, it is apparent that these embodiments may also be implemented without these specific details. In other examples, for ease of describing one or more embodiments, known structures and devices are shown in the form of block diagrams.
[0020] See also Figure 1-9 The present embodiment provides a thin-wall hinge mounting structure of a back-mounted rear bumper plate and a lower bumper skin, comprising: a rear bumper plate 1, and a lower bumper skin 2 connected to the rear bumper plate 1. Bendable connecting pieces 4 are integrally formed on both sides of the rear bumper plate 1, and a plurality of buckles 3 are evenly arranged on the upper end of the rear bumper plate 1. The bendable connecting piece 4 is fixedly connected to the lower bumper skin 2 of the rear bumper by means of pull rivets 5. The bendable connecting piece 4 is used for adjusting the folding angle between the rear bumper plate 1 and the lower bumper skin 2 during assembly, and the upper end of the rear bumper plate 1 is fixedly connected to the lower bumper skin 2 of the rear bumper by means of buckles. The bendable connecting piece 4 comprises: a bending portion 401 connected to the rear bumper plate 1, and a fixing portion 402 connected to the lower bumper skin 2 of the rear bumper. The fixing portion 402 is provided with a plurality of rivet holes, and pull rivets 5 are installed at positions corresponding to the rivet holes on the lower bumper skin 2 of the rear bumper.
[0021] Working principle: bendable connecting pieces 4 are processed on both sides of the rear bumper plate 1, and the bendable connecting pieces 4 allow the rear bumper plate 1 and the rear bumper lower skin 2 to be folded at different angles during assembly. The bendable connecting pieces 4 are processed by thinning the edges of both sides of the rear bumper plate 1 at the positions where they need to be bent to form thin-walled hinges, so that the area can be folded at will.
