[0016] like Figure 1-4 As shown, the new grille fastening structure of the present invention is that after the wireless charging panel M covered with a foreskin P is installed on the back of the heat dissipating grille G, the grille G and the panel M welding area G2 are punctured and welded to fasten and fix. The utility model includes a panel M and a grille G. The front of the panel M is the panel front M1, which has a functional opening M3. The panel front M1 is covered with a decorative foreskin P, and its back is the panel inner surface M0. The front of the grille is the grille front G1, and the back is the grille inner surface G0. The grille G is provided with a welding area G2 and a positioning area G3. The panel M also has a corresponding welding area (connection area) and a positioning area. The positioning area G3 of the grille G and the positioning area of ​​the panel M are respectively provided with concave and convex positioning structures. The grille G welding area G2 and the corresponding welding area of ​​the panel M are at least two.

[0017] The utility model discloses a new type of grille fastening structure, that is, a structure in which the panel M and the grille G are fixedly connected by puncture welding. The puncture welding is also called spot welding, which uses an electrode to achieve the welding and fixing of the panel M and the grille G through high-frequency heating. The puncture welding process is simple, and the high-frequency "puncture" speed of the electrode is fast. In this embodiment, the grille G is first aligned with the inner surface M0 of the panel M with the front surface G1 of the grille, and positioned and installed through the positioning structure of the grille positioning area G3 and the panel M positioning area. Then, the puncture welding head is aligned with the welding area G2 of the inner surface G0 of the grille to perform welding. The welding head forms a matrix of weld fixed connection points in the welding area, and the welding depth is the thickness of the grille plus 0.8-1mm. In this embodiment, the matrix is ​​2 rows and 4 columns, which makes the fixed connection between the panel M and the grille G more firmly.

[0018] The above description is merely a general embodiment of the present invention. Those skilled in the art will readily appreciate that the present invention may have various modifications and variations, which are not exhaustively described here. However, any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection claimed by the present invention.
