Description

Technical Field

[0001] This invention relates to the field of automotive exterior plastic technology, and in particular to a method for assembling inner and outer panels of a spoiler that absorbs deformation. Background Technology

[0002] With the rapid development of automobile manufacturing technology and processes, OEMs have increasingly higher requirements for the appearance of plastic spoilers. Solving the problem of appearance dents caused by deformation of large-sized parts has become a technical pain point. Because it is necessary to control the dimensional accuracy of parts, this inevitably puts forward higher requirements for mold design and injection molding process, which will inevitably increase manufacturing costs, reduce the single-piece pass rate, and increase the defect rate.

[0003] Causes of dents on the exterior of plastic spoilers: Due to their excessive size, the inner spoiler panel deforms after leaving the mold, following the styling trend. This deformation is significant, resulting in dimensional inconsistencies. When bonding with the outer spoiler panel, the inner panel, being more rigid, deforms and tightens along with it. Ultimately, after the inner and outer spoiler panels are connected to the vehicle body sheet metal, the sheet metal, being more rigid than the plastic spoiler, forcibly pulls the fastening points back, causing dents at these points. Current technology typically addresses these dents through repeated process adjustments and vehicle modifications. However, these engineering changes increase costs and time, and can lead to unstable part conditions. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a method for assembling inner and outer plates of a spoiler that absorbs deformation, which is the main innovation.

[0005] The present invention also provides an assembly method for the inner and outer panels of a spoiler that absorbs deformation, wherein the spoiler includes an upper outer panel, a lower outer panel, an inner panel, and a body sheet metal. The upper outer panel and the lower outer panel are bonded to the inner panel with adhesive. Seven mounting points are provided between the body sheet metal and the inner panel, and flexible structures are provided on both sides of the mounting points.

[0006] The assembly method includes the following steps:

[0007] S1. The upper and lower outer panels are glued to the inner panel to form a flexible structure on both sides of the mounting point of the inner panel and the body sheet metal.

[0008] S2. Install the components connected in S1 onto the vehicle body sheet metal using bolts, according to the mounting points.

[0009] According to the present invention, the inner and outer plates of a deformation-absorbing spoiler are assembled in a manner in which the mounting points are divided into a first mounting point, a second mounting point, a third mounting point, a fourth mounting point, a fifth mounting point, a sixth mounting point, and a seventh mounting point, and the mounting points are connected by bolts.

[0010] According to the present invention, in the assembly method of inner and outer plates of a deformation-absorbing spoiler, when forming a flexible mechanism in S1, the glue is broken at the flexible structure and the glue is only applied to both sides of the mounting point.

[0011] Beneficial effects

[0012] This invention achieves a flexible connection between the inner and outer panels, with the outer panel absorbing the deformation of the inner panel while ensuring the strength and rigidity between them. This prevents dents from appearing on the exterior of the spoiler assembly after it is assembled with the vehicle body due to deformation of the inner panel, thus solving the appearance problem while greatly increasing the manufacturing and assembly tolerances of the inner panel and expanding the manufacturing process window for the inner panel.

[0021] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0022] Reference Figure 1-5 This invention discloses an assembly method for inner and outer panels of a spoiler that absorbs deformation, comprising: a spoiler including an upper outer panel 1, a lower outer panel 2, an inner panel 4, and a body sheet metal 3; the upper outer panel 1 and the lower outer panel 2 are bonded to the inner panel 4 with adhesive 5; seven mounting points are provided between the body sheet metal 3 and the inner panel 4; the mounting points are divided into a first mounting point 7, a second mounting point 8, a third mounting point 9, a fourth mounting point 10, a fifth mounting point 11, a sixth mounting point 12, and a seventh mounting point 13; the mounting points are connected by bolts; and flexible structures 6 are provided on both sides of the mounting points for the inner panel 4 to absorb deformation.

[0023] The assembly process includes the following steps:

[0024] S1. The upper outer panel 1 and the lower outer panel 2 are bonded to the inner panel 4 with glue 5, so that the inner panel 4 and the mounting point of the body sheet metal 3 form a flexible structure 6 on both sides. Through the flexible design 6 of the inner panel 4 and the flexible connection between the inner and outer panels with glue 5, the deformation of the inner panel is absorbed and the appearance defects caused by large-size manufacturing tolerances are solved.

[0025] S2. Install the components connected in S1 onto the body sheet metal 3 with bolts according to the mounting points. The mounting points 7 to 13 are the same as the theoretical positions, so as not to pull out dents on the outer panel of the spoiler.

[0026] When forming the flexible mechanism in S1, the glue 5 is broken at the flexible structure and only flows on both sides of the mounting point. This ensures the strength of the inner and outer panels, while fixing the deformed inner panel 4 to the undeformed upper outer panel 1 and lower outer panel 2. Since the outer panel is divided into upper outer panel 1 and lower outer panel 2, each of which is half the size of the inner panel 4, its dimensions are stable after it comes out of the mold and will not deform, meeting the single-piece size requirements.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
