In the present invention, a bumper of a vehicle refers to front bumper of the vehicle or rear bumper of the vehicle. A grill includes the grill of the traditional oil-fueled automobile and air intake grill and enclosed grill of the electric automobile.

The bumper assembly of the vehicle usually includes an ornament, a medium part and a bumper skin. Wherein, in the front bumper assembly, the medium part may be grill, or the grill with other parts, such as grill frame or lamp sets. After being assembled, since there are more superimposed parts, the bumper skin has a larger impending space along the length of the vehicle body, or because of the factors as the weight thereof or other parts loaded thereon, it will cause the bumper skin sinking (with relative displacement), and form a larger gap between the ornament, and sometimes, the height of such gap will be greater than 0.5 millimeters, even up to 2-3 millimeters. Such gap seriously affects the vehicle structural integrality and the aesthetic. Therefore, it needs to reset the structures of each part and the connections between the parts in the bumper assembly.

Figure 1 and figure 2 show the schematic view of the bumper assembly of the exemplary embodiment of the present invention. Figure 3 shows the exploded view of figure 1. After the ornament 100 is assembled with the grill 200 and the grill frame 201 in turn, and then it is installed to the front bumper skin 300. In the alternative embodiment, the grill frame 201 is configured to be integrated with the grill 200. That is, the medium part is configured as an integrated structure or a grill after being integrated assembled. As shown in figure 3, the ornament 100 includes an ornament body 102 and six buckles 104 arranged at intervals along the lengthwise direction of the ornament body 102, and the buckles 104 are symmetrically arranged that is centered on the vehicle logo (not shown) which is in the middle of the ornament 100. The six buckles 104 are corresponding to six hooks 204 (shown in figure 4) on the grill 200 respectively, in order to engaged pair to pair. As shown in figure 4, figure 4 shows the sectional view along A-A direction of figure 1. The ornament 100 and the front bumper skin 300 form gap 400 at the head of the vehicle. The ornament 100 is engaged with the grill 200 with the buckles 104, which it limits the displacement along the horizontal direction relative to the grill 200 at least. It should be understood that, in some embodiments, according to the changes of the size and the structure of the ornament and the grill, the buckles and the hooks with other corresponding quantity and shape can be set.

Figure 5 shows the schematic view of the ornament and the front bumper skin of the exemplary embodiment of the present invention. Figure 6 shows the partial structure view of the ornament and the front bumper skin of the exemplary embodiment of the present invention. The front bumper skin 300 in figure 5 is provided with engaging surface 308, and such engaging surface 308 is arranged along the lengthwise direction (approximately along the width of the car) of the front bumper skin body 302, on which four grooves 306 arranged at intervals regard as receiving part. In figure 6, the ornament 100 not only shows the buckles 104, but also shows first gaggers 106 and second gaggers 108. Wherein, the first gaggers 106 are regarded as first components, and the second gaggers 108 are regarded as second components. Furthermore, the quantity of the first gaggers 106 shown in figure 6 is two (the other two first gaggers of the ornament are not shown in figure 6), the quantity of the second gaggers 108 is four (the other four second gaggers of ornament are not shown in figure 6). Wherein, two fist gaggers 106 in figure 6 are matched with the corresponding two grooves 306 in figure 5. Combining with figure 8, the first gaggers 106 and the second gaggers 108 are located in the same row (such row does not have to be a horizontal straight line), while the buckles 104 are located in the other row. Moreover, the first gaggers 106 and the second gaggers 108 are arranged in staggered and intersected way, which do not be intervened with each other. In figure 6, the first gaggers 106 and the second gaggers 108 are both configured as an approximately tabular structure. Wherein, the length-width ratio of the first gaggers 106 is greater than that of the second gaggers 108, in other words, the first gaggers 106 are more slender. In consideration of the quantity of the first gagger 106 is less than the quantity of the second gagger 108, by such arrangement, when the ornament is installed to the front bumper skin, the first gaggers 106 may be not only aligned and inserted into the grooves 306 easily and effortlessly, but also the slender first gaggers 106 may limit the rotary movement of the ornament relative to the front bumper skin better. Alternatively, the quantity of the first gaggers 106 is half that of the second gaggers 108.

In the embodiment shown in figure 7, the grooves 306 are provided with openings 307, in order to be suitable for inserting the first gaggers 106, and the openings 307 are arranged along the horizontal direction.
