Because the product is installed on the front bumper of the car, the existing electroplated radiator grille trim structure mainly has problems such as abnormal assembly noise, warping at both ends, and deformation after assembly.

[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] In the figure, the decorative strip body 100; the small boss 200; the base platform 300; the Z-axis through hole 301; the Y-axis slider escape through hole 302; the long insert 400; the circular claw 500; the side insert 600; the break difference parting line 700; and the foot of the circular claw 800.

[0019] like Figure 1 As shown, the electroplated radiator grille trim structure includes a trim body 100, on which claw assemblies and self-tapping assemblies are arranged, the claw assemblies are arranged at intervals along the transverse extension plane of the trim body 100, the self-tapping assemblies are arranged at both ends of the trim body 100, and the trim body 100 has a small boss 200. Here, the point contact of the small boss 200 ensures the stability of the assembly of the hand parts, prevents poor assembly caused by large-surface zero-sticking, and prevents abnormal noise between the electroplated and painted parts.

[0020] like Figure 2 As shown, specifically, the self-tapping component is a doghouse-shaped base platform 300, and a Z-direction through hole 301 and a Y-direction slider escape through hole 302 are provided in the base platform 300. The doghouse-shaped base platform 300 simplifies the mold structure, and the mouth-shaped structure ensures the assembly strength of the product. At the same time, the installation points at both ends are very close to the two ends, which can effectively control the warping. Similar long electroplated decorative strips have very common warping at both ends in the industry. The Z-direction through hole 301 and the Y-direction slider escape through hole 302 can ensure the leakage function of the electroplating process, prevent the occurrence of liquid accumulation due to the surface tension of the liquid during electroplating, and thus avoid the occurrence of tank liquid contamination.

[0021] like Figure 4 As shown, the claw assembly includes at least one group of circular plug-in feet and two long plug-in assemblies. The two long plugs 400 are located at the two ends of the upper side of the trim strip body 100, and the circular plug-in feet are located in the middle of the lower side of the trim strip body 100. Here, the long plug 400 can be used as an electroplating hanging foot, which can not only ensure the electroplating process of the product, but also, compared with the previous bad reviews, this long plug 400 does not need to be broken, which can ensure the matching of the surface difference after the upper and lower sides are assembled. In the past, similar process plugs needed to be cut off after completing the process flow, which was very time-consuming and easy to produce residues, scratch the opponent or cause abnormal noise in the assembly. The circular plug-in foot includes a circular claw 500 and a side plug 600. The height of the side plug 600 is higher than the circular claw. Here, two The strong side insert 600 can not only ensure the Z-direction positioning of the product, but also withstand the shear force of the product in the Z-direction through both ends, thereby preventing the problem of breakage of the previous circular claw 500. In the past, similar claws only had a separate middle structure. When the product was subjected to the shear force in the Z-direction, it was very easy to break. Because the space on the flange is very limited, the thickness of the claw will not be very thick. Normally, this circular structure that does not require deformation often causes the root of the product to break due to the assembly shear force generated by the deformation of the product after electroplating. The side insert 600 and the long insert 400 have guide bevels. The guide bevels here ensure the assembly guidance and blind installation requirements of the product. After the connection, the insert can be flipped over and self-tapping screws can be driven to prevent the product from falling off, thereby simplifying the product process.

[0022] like Figure 3 As shown, the decorative strip body 100 has a step difference parting line 700, which can facilitate the matching of the parting surface of the injection mold. After mass production, long-term collision and wear will cause flash, such as Figure 5As shown, as an optimization, the foot 800 of the toggle claw is asymmetrical, which can prevent the problem of the weld line breaking in the middle of similar to the toggle structure in the past. Such a structure can move the weld line to the rounded corner, and the strength of the product clamping surface can be guaranteed. The structure is assembled with the front bumper of the car to play a decorative role, and the sub-parts of the component are all one-piece injection-molded resin products. The overall structure is suitable for electroplating process, and attention should be paid to the deformation problem caused by temperature change in the plating tank during the polymer solidification process after injection molding and during electroplating, and attention should be paid to the reduction of injection stress and pressure.

[0023] The specific embodiments described in this article are merely examples of the spirit of the present invention. Technicians in the technical field to which the present invention belongs may make various modifications or additions to the described specific embodiments or replace them in a similar manner, but they will not deviate from the scope defined by the spirit of the present invention.
