[0023] The following are specific embodiments of the present invention and in combination with the attached drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0024] In the figure, main body part 100; upper side part 200; lower side part 300; rhombic part 400; arc-shaped notch 500; backbone 600; claw part 700; upper welding piece 800; lower welding piece 900; loop-shaped card slot 1000; U-shaped card slot 1001; end welding piece 1002; bump 1003; bevel surface 1004.

[0025] As Figure 1 shown, the painted radiator grille trim structure applicable to ultrasonic welding includes a main body part 100, the main body part 100 is divided into an upper side part 200, a lower side part 300 and a rhombic part 400 formed between the upper side part 200 and the lower side part 300. As Figure 7 shown, the rhombic part 400 has an arc-shaped notch 500, the upper end flange of the arc-shaped notch 500 is short, and the lower end flange is long. This not only ensures the appearance effect of the whole vehicle but also meets the requirements of the painting process (the oblique spraying angle requirement of the automatic painting line for painting). The upper flange is cleverly shortened and the lower flange is lengthened. Therefore, when viewed from a 45-degree angle from the front of the vehicle, there will be a good appearance effect.

[0026] As Figure 3 shown, the back of the main body part 100 has an arched backbone 600 running through the left and right. Here, there is an arched backbone 600 acting as a whole central axis on the back, which can ensure the rigidity of the overall radiator grille trim and avoid the warping and deformation problems caused by the grille trim structure. In the past, similar long grille trims were very prone to deformation during high-temperature baking in the painting line because the structure of the product was very limited, and the structure that could increase strength was extremely likely to cause shrinkage (high-temperature baking, deformation of injection molded parts). The design of the arched backbone 600 of the present invention greatly increases the overall strength of the product.

[0027] As Figure 2As shown, a plurality of claw members 700 and upper welding tabs 800 are arranged on the upper side portion 200. The claw members 700 and the upper welding tabs 800 are arranged in an alternating and spaced manner. On the lower side portion 300, a lower welding tab 900 and a loop-shaped card slot 1000 are arranged. The claw members 700 and the upper welding tabs 800 are arranged in an alternating and spaced manner in an upper and lower hierarchical structure and are not on the same straight line. Here, the alternating structure of the installation points of the claw members 700 and the upper welding tabs 800 ensures the assembly strength of the overall product. At the same time, it can also prevent the serpentine deformation of the long decorative strip and play a role in assembly shaping. The product structure design of the present utility model fully considers this point. Through the cooperation of the double-row structure of the claw members 700 and the upper welding tabs 800, the shaping and stable reliability of the overall assembly of the product are ensured, and the alternating assembly structure with a sense of hierarchy is formed.

[0028] The lower welding tab 900 and the loop-shaped card slot 1000 are arranged in an alternating and spaced manner. Here, the cooperation of the alternating assembly structure with a sense of hierarchy of the installation points and the double-row structure ensures the assembly strength of the overall product. At the same time, it can also prevent the serpentine deformation and warping problems of the long decorative strip and play a role in assembly shaping. The claw members 700 on the upper side portion 200 and the loop-shaped card slot 1000 on the lower side portion 300 are in an oblique direction. Here, the claw members 700 and the loop-shaped card slot 1000 can be used to realize the pre-installation structure of the overall grille decorative strip, simplify the assembly process and the reliability of the decorative strip. The oblique arrangement of the claw members 700 and the loop-shaped card slot 1000 on the upper and lower sides just separates the mating points, which can ensure the stability of the overall pre-assembly of the product. On this basis, the product will not fall off when it is flipped, simplifies the installation process, and is conducive to the ultrasonic welding of the next process. The loop-shaped card slot 1000 is hidden, which can ensure that the loop-shaped card slot 1000 cannot be seen when looking down at the vehicle body at a 45-degree angle, and at the same time, it can ensure the connection of the mechanical structure on the lower side of the product.

[0029] As Figure 4 shown, a U-shaped card slot 1001 is provided at the lower part beside the loop-shaped card slot 1000. Here, the mating part is just embedded in the U-shaped card slot 1001. By setting the U-shaped card slot, the support of the alternating structure between the grille body and the decorative strip is ensured, which greatly improves the strength of the overall assembly and the tightness of the assembly. As Figure 5As shown, end welding tabs 1002 are provided at both ends of the main body 100. In the present utility model, by adding end welding tabs 1002 in the visually invisible area of the end corner space, mechanical connection is ingeniously increased within the limited space, ensuring the surface difference fit at both ends of the product. The newly added mounting points at both ends prevent the end warping problem that is prone to occur in long decorative strips. Convex points 1003 are provided on both sides of the claw member 700, the upper welding tab 800, and the lower welding tab 900. Through the convex point 1003 structure, a point contact structure between the overall grille trim and the grille body can be ensured, preventing the occurrence of wiping abnormal sounds between the painted surfaces (all convex points are on the back, and the material will not be painted), and at the same time, it is very beneficial for correcting the mounting surface during assembly.

[0030] As Figure 6 shown, the upper welding tab 800 and the lower welding tab 900 have beveled surfaces 1004. Here, the beveled surfaces 1004 are relatively thin. By means of the beveled surfaces 1004, the requirement for guiding the initial melting of the welding sheet is ensured. At the beginning of ultrasonic welding, since both materials are taken after injection molding and then welded, the welding sheets of the product are cold. Therefore, the relatively thin product wall thickness is very beneficial for guiding the melting, thereby promoting the improvement of production efficiency. The diamond-shaped portion 400 has a wall thickness reduction portion. In this way, while balancing the limited space and shape of the whole vehicle, both the strength of the mold and the appearance function requirements of the product without shrinkage on the appearance are ensured. Uneven wall thickness reduction of the upper and lower parts prevents insufficient mold strength. The main body 100 has a parting step portion. In this way, while meeting the process requirements of the injection mold matching, the shaping concept of the shaping department of the vehicle factory is ensured, resulting in the occurrence of flash.

[0031] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art of the present utility model can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the scope defined by the spirit of the present utility model.
