[0034] The technical solutions of the present application will be described in detail below in combination with the drawings and examples.

[0035] As Figures 1-7As shown, the dot matrix grille in the embodiment includes a grille body 1 and a grille decoration assembly, the grille decoration assembly includes a plurality of first grille decoration pieces 2, a plurality of the first grille decoration pieces 2 are fixed on the rear side of the grille body 1 along the left-right direction; each of the first grille decoration pieces 2 includes a plurality of first decoration particles 21 arranged in intervals from top to bottom and a first connecting material bridge 22 arranged between two adjacent first decoration particles 21, each of the first connecting material bridges 22 is provided with a first welding hole 222; the grille body 1 is provided with a first hollow opening 11 corresponding to each of the first decoration particles 21, the first decoration particle 21 can be inserted into the corresponding first hollow opening 11 and exposed forward; the grille body 1 is provided with a shielding part 12 corresponding to each of the first connecting material bridges 22, the shielding part 12 is provided with a first welding rib 13 protruding backward, the first welding rib 13 can be inserted into the corresponding first welding hole 222 and welded by hot riveting. According to the modeling design intention, the first decoration particles 21 are arranged in advance with a predetermined size, the first decoration particles 21 are connected into one part by the first connecting material bridge 22, each of the first decoration particles 21 is only needed to be inserted into the corresponding first hollow opening 11, then the first welding rib 13 is inserted into each of the first welding holes 222, and the assembly of the first grille decoration piece 2 can be realized by hot riveting, which can reduce the assembly difficulty, make the decoration piece with smaller appearance size easily connected with the grille body 1, and does not need to assemble the first decoration particles 21 one by one, is conducive to reducing the assembly cost, improving the assembly efficiency, facilitating the control of production rhythm, and the hot riveting has better firmness, without pressing loose, abnormal sound and other problems, without the need of screw fixing, avoids that the traditional grille occupies a large space due to the arrangement of screws, and greatly improves the modeling design freedom. At the same time, the weight of the parts, the cost of screw investment and the cost of manual assembly are also reduced. After assembly, the first decoration particle 21 is exposed from the first hollow opening 11 as an appearance visible area, the first connecting material bridge 22 is hidden behind the grille body 1 as an invisible area, and a dot matrix appearance effect is formed. On the other hand, the first grille decoration piece 2 is injection molded as a whole, which overcomes the defect of high processing cost caused by separate mold opening of each first decoration shell. A plurality of first grille decoration pieces 2 can be divided according to the modeling design, to realize single-color or multi-color effect, so that the product is more advanced, fashionable and visually striking.
