[0018] The present invention is further described below in conjunction with embodiments and drawings.

[0019] like Figure 1 and Figure 3 As shown, a front bumper borderless grille structure mainly includes a grille body 1 and a plurality of painted decorative parts 2.

[0020] See also Figure 1-Figure 4 The grille body 1 is provided with a decorative protrusion arrangement area, in which a plurality of decorative protrusion mounting holes 11 are provided. The decorative protrusion mounting holes 11 may be evenly distributed, array-distributed, or randomly distributed. The decorative protrusion arrangement area is composed of at least two decorative component sub-areas, each of which has at least two decorative protrusion mounting holes 11. In this embodiment, the decorative protrusion arrangement area is composed of a plurality of decorative component sub-areas, each of which has a plurality of decorative protrusion mounting holes 11. There are grille sheet ribs 12 formed on the grille body 1 between each adjacent decorative protrusion mounting hole 11, each of which is a sheet-like structure, and each of which protrudes inward.

[0021] See also Figure 1 , Figure 2 as well as Figure 4-Figure 7 Each decorative element sub-area is provided with a painted decorative element 2 mounted on its inner side. Specifically, the painted decorative element 2 has a decorative protrusion 21 adapted to the corresponding decorative protrusion mounting hole 11 and a sheet rib mounting sleeve 22 adapted to the corresponding grille sheet rib 12.

[0022] Each decorative protrusion 21 protrudes outward from the corresponding decorative protrusion mounting hole 11 to the outside of the grille body 1, so that the A-side shape of the front bumper grille is composed of a large number of decorative protrusions 21, which is not only three-dimensional but also very technological. Therefore, in this embodiment, the decorative protrusion arrangement area of ​​the grille body 1 is divided into several decorative part sub-areas, each decorative part sub-area is only installed with one spray-painted decorative part 2, and each spray-painted decorative part 2 is integrated with multiple decorative protrusions 21, so that multiple decorative protrusions 21 can be assembled at one time, which not only greatly improves the assembly efficiency and reduces the assembly time, but also each spray-painted decorative part 2 corresponds to multiple continuous decorative protrusion mounting holes 11, which is very obvious visually and will not cause the problem of missing installation. At the same time, the shape and size of each spray-painted decorative part 2 can be designed to be significantly different, so as to avoid the problem of wrong installation.

[0023] A decorative part limiting surface 221 is formed on the end surface of each rib mounting sleeve 22 close to the inner side of the painted decorative part 2, and a strip-shaped through-hole 222 is opened on each decorative part limiting surface 221 for the corresponding grille rib 12 to pass through. After each grille rib 12 passes through the corresponding strip-shaped through-hole 222 toward the inner side of the grille body 1, it is locked by the metal clip 3.

[0024] Specifically, the metal clip 3 is made of metal material, and the metal clip 3 includes a top plate 31 and side plates 32 extending downward from the outer edges of both sides of the top plate 31, the top plate 31 and the two side plates 32 together constitute an n-shaped sheet structure, the top plate 31 is provided with a sheet rib limiting hole 311 adapted to the corresponding grille sheet rib 12, the upper end of each grille sheet rib 12 protrudes from the corresponding sheet rib limiting hole 311, the lower edges of the two side plates 32 of the metal clip 3 are bent in a direction away from each other to form a limiting plate 33 adapted to the corresponding decorative part limiting surface 221, each limiting plate 33 is supported on the corresponding decorative part limiting surface 221, the two side plates 32 of the metal clip 3 are provided with tooth undercuts 34 deflected in a direction approaching each other, each tooth undercut 34 is respectively stuck on the side wall of the corresponding grille sheet rib 12, and the pull-out force of the metal clip 3 designed in this way can reach more than 120N. Therefore, the grille rib 12 is locked on the rib mounting sleeve 22 of the painted decorative part 2 by the metal clip 3. Not only is the installation stable, reliable, convenient and quick, but it can also be effectively disassembled by forcing the metal clip 3 to deform without damaging the grille body 1, thereby avoiding the problem of the entire front bumper grille being scrapped due to quality defects in any decorative protrusion.

[0025] For further information, see Figure 2, each decorative part limiting surface 221 is provided with a guide boss 223 respectively located at both ends of the length direction of the corresponding strip-shaped through hole 222, so that the metal clip 3 can be limited between the two guide bosses 223. It can not only guide the installation of the metal clip 3, but also play a role in positioning the metal clip 3, which is simple and reliable. Therefore, the upper end of the guide boss 223 close to the side of the metal clip 3 is a guide slope 223a inclined outward, so that the two guide slopes 223a on the two adjacent guide bosses 223 form an open structure with a gradually decreasing distance from the outside to the inside, which further facilitates the installation of the metal clip 3 and avoids the problem of jamming. Furthermore, the upper end of the grille sheet rib 12 is a structure that is narrow at the top and wide at the bottom, so that it is easier for the sheet rib limiting hole 311 to limit the grille sheet rib 12.

[0026] For further information, see Figure 2 , Figure 4 and Figure 6 A plurality of partition ribs 121 are provided on both side walls of the grille sheet rib 12, and each partition rib 121 extends along the length direction of the grille sheet rib 12 and is located between two corresponding tooth undercuts 34. This not only limits the position of each tooth undercut 34, but also prevents the tooth undercut 34 from slipping, making the tooth undercut 34 more firmly stuck, thereby further improving the extraction force of the metal clip 3.

[0027] For further information, see Figure 5 The painted decorative parts 2 are all long strip structures, and each decorative protrusion 21 extends along the length direction of the corresponding painted decorative part 2. Both ends of the painted decorative part 2 are provided with mounting brackets 23, and the decorative part sub-area is provided with mounting seats 13 respectively adapted to the corresponding mounting brackets 23. Each mounting bracket 23 is respectively mounted on the corresponding mounting seat 13 by screws, thereby further improving the reliability of the installation of the painted decorative part 2 and avoiding the problem of the painted decorative part 2 being loose.

[0028] Since the surface of the painted decorative part 2 is sprayed with a painting process, and the protruding height of the existing decorative protrusion 21 is too high, the side of the decorative protrusion 21 may not be painted properly, so that after the painted decorative part 2 is assembled on the grille body 1, the thin spray position is exposed, resulting in a poor paint appearance on the borderless grille A surface of the front bumper. If the protruding height of the decorative protrusion 21 is simply reduced, the three-dimensional sense of the borderless grille A surface of the front bumper will be significantly reduced.

[0029] Therefore, see Figure 8The height of the decorative protrusion 21 protruding from the corresponding decorative protrusion mounting hole 11 is less than or equal to 5mm, which can prevent the thin spray position from being exposed and solve the problem of poor spray appearance. At the same time, the upper edge of the decorative protrusion 21 protruding from the corresponding decorative protrusion mounting hole 11 has a bevel chamfer 211, and an arc transition is adopted between the bevel chamfer 211 and the decorative protrusion 21, changing the traditional right-angle appearance of the decorative protrusion 21 into a large bevel C-angle chamfer shape, greatly improving the three-dimensional sense of the A surface of the borderless grille of the front bumper.

[0030] Due to styling reasons, the painted decorative parts 2 can only be assembled from back to front. The painted decorative parts 2 are usually ABS material painted parts, and the grille body 1 is usually high-gloss PMMA / ASA or leather-grained ASA material. Therefore, the hardness of the grille body 1 is higher than that of the painted decorative parts 2, which leads to problems such as paint damage, loosening of the painted decorative parts 2 and light leakage when assembling the painted decorative parts 2.

[0031] Therefore, see Figure 5 and Figure 8 The inner opening of the decorative protrusion mounting hole 11 has an R-angle chamfer 111. In this embodiment, the arc radius of the R-angle chamfer 111 is 1 mm, so that the decorative protrusion 21 will not be damaged when it hits the inner opening of the decorative protrusion mounting hole 11.

[0032] At the same time, a plurality of limiting ribs 212 are distributed on the upper and lower surfaces of the decorative protrusion 21, and each decorative protrusion 21 is supported in the corresponding decorative protrusion mounting hole 11 by the limiting ribs 212, which greatly improves the reliability of the installation of the decorative protrusion 21 and is not easy to loosen. Furthermore, the front end of the limiting rib 212 adopts a slope structure, so that it can play a guiding role during installation and reduce the difficulty of installation.

[0033] In addition, the cross-section of the decorative protrusion 21 is an N-shaped structure with an opening facing backwards, and the upper and lower outer edges of the decorative protrusion 21 are folded outward to form a shielding flange 213 to shield the gap between the hole wall of the decorative protrusion mounting hole 11 and the outer wall of the decorative protrusion 21, thereby solving the problem of light leakage.
