Description

Interactive screen circuit board mounting structure of automobile tail lamp Technical Field The utility model relates to the technical field of automobile lamp assembly, in particular to an automobile tail lamp interactive screen circuit board mounting structure. Background When the automobile lamp circuit board is installed and fixed inside, the automobile lamp circuit board is required to be installed and fixed with peripheral components through an installation structure, and at present, fixing structures such as screws, riveting and clamping are mainly used, so that the required installation space is large. Because the LEDs are densely distributed in the middle of the automobile tail lamp interactive screen circuit board, the mounting structure cannot be arranged, the size of the circuit board can be increased, and then the mounting structures such as screws, riveting and clamping are arranged at the edge, so that the required mounting space is large, and the modeling of a host factory is not used for arranging the mounting structure in a large space for the whole automobile effect, so that the appearance modeling of the whole automobile is not influenced, and the mounting is firm and stable, and is a difficult problem for the mounting of the circuit board. Disclosure of utility model The utility model aims to solve the technical problem of overcoming the defects of the prior art and providing the mounting structure of the circuit board of the interaction screen of the automobile tail lamp, which is arranged on the back of the LED circuit board without occupying appearance modeling space. In order to solve the technical problems, the technical scheme of the utility model is as follows: The mounting structure of the automobile tail lamp interactive screen circuit board comprises a lamp shade and a shell which are assembled, wherein a bracket is arranged in the shell, and a decorative ring is arranged at the front part of the bracket; An LED circuit board is arranged between the decorative ring and the support, a plurality of welding nuts are arranged on the back side, close to the support, of the LED circuit board, a plurality of locking screws corresponding to the welding nuts are assembled on the support in a penetrating manner, and the LED circuit board is assembled and fixed with the support through locking cooperation of the welding nuts and the locking screws. Further, a groove line is formed on one end face, close to the LED circuit board, of the welding nut. Further, the upper surface of the welding nut, which is close to one end surface of the LED circuit board, is plated with tin. Further, the welding nut is made of copper alloy or carbon steel. Further, the front side of the support is further provided with a limiting structure corresponding to the welding nut, and the welding nut and the limiting structure are aligned and limited. Further, the front side of the LED circuit board, which is close to the decorative ring, is provided with a plurality of LED light sources. By adopting the technical scheme, the utility model has the following beneficial effects: 1. According to the utility model, the welding nuts are welded and arranged on the back of the LED circuit board, and the LED circuit board can be firmly installed and fixed on the front side of the bracket through the locking screw assembled on the bracket in a penetrating way and the locking fit with the welding nuts, so that the installation structure is not required to be arranged on the front side and the edge of the LED circuit board, the integral size can be reduced, the internal space is not occupied, the external modeling is not influenced, and the modeling requirement of a host factory is more easily met. 2. According to the utility model, the welding nut is provided with the forming groove lines on one end face close to the LED circuit board, and the surface is plated with tin, so that the welding area and the welding strength are increased, the fixing firmness is further increased, and the mounting stability with peripheral components is ensured.
