Background
The automobile tail lamp is assembled at the tail part of an automobile, and the mounting structure is that a lamp forming the automobile tail lamp is fixed on a metal plate of the automobile body at the tail part of the automobile through three mounting screws. At present, the most common lamp mounting structure is: and the lamp is fixed with a metal plate of the automobile body at the tail part of the automobile in a metallographic mode by adopting a hot screw. Specifically, as shown in fig. 1 and 2, the lamp constituting the automobile tail lamp includes a lamp housing 100, the lamp housing 100 having a screw mounting hole 101 and a limit boss 102 for contacting with a heat screw 200; the hot stamping screw 200 includes a hot melt portion 201 that is stamped into the lamp housing 100, a flange portion 202 for contacting the body sheet metal 300 and the limit boss 102, and a screw portion 203 with an external thread tapped at the outer periphery. The method for fixing the lamp to the sheet metal 300 of the vehicle body by using the blanching screw 200 with the structure comprises the following steps: firstly, welding a lens assembly in a lamp and a lamp housing 100 into a whole (namely, a lamp assembly), and fixing the lamp assembly through a fixture; then, the heat-fused portion 201 of the heat-seal screw 200 is fitted into the screw mounting hole 101 of the lamp housing 100, and the heat-fused portion 201 of the heat-seal screw 200 is heated; because the lamp housing 100 is made of plastic, the diameter of the screw mounting hole 101 of the lamp housing 100 is smaller than the diameter of the hot melt part 201 of the hot melt screw 200, so the hot melt part 201 of the hot melt screw 200 is melted into a whole with the lamp housing 100 after being heated, wherein the limit boss 102 on the lamp housing 100 is matched with the flange part 202 of the hot melt screw 200 for limiting; after cooling, the installation of the blanching screw 200 fixed in the lamp housing 100 is completed; finally, the three hot screws 200 on the lamp housing 100 are aligned to the mounting holes on the metal plate 300 of the vehicle body, and after positioning, the screw portions 203 of the hot screws 200 are screwed down by nuts, so that the lamp housing 100 and the metal plate 300 of the vehicle body can be fixed, and the installation of the lamp assembly and the metal plate 300 of the vehicle body is completed.
From the above, it can be seen that: the mounting structure using the hot screw requires a special design of a procedure in the production process of the automobile tail lamp: and after the three scalding screws are heated, the scalding screws and the lamp housing made of plastic materials are fused into a whole through the special fixture. Therefore, although the lamp mounting structure including the hot screw has high reliability, there is a certain disadvantage: if special fixtures are required to be designed for installing the hot screws in the production process, the working procedures of lamp production are increased, and the process installation errors for fixing the hot screws through the hot working procedures are large, so that the positioning accuracy cannot be guaranteed.
