Description

Technical Field

[0001] The utility model relates to the technical field of automobile brackets, in particular to a positioning bracket for an automobile door sill guard plate. Background Art

[0002] A threshold guard is provided under the car door. The threshold guard mainly serves as a decoration and is used to provide stepping support for the occupants when entering and exiting the vehicle. Since the surrounding environment of the threshold guard is relatively complex, including side panel metal, floor, wiring harness, carpet, etc., the shape of the threshold guard is mostly special-shaped parts, which requires high precision in processing and installation. If the angle is inaccurate during processing, it will cause warping or incompatibility during the installation process, affecting the later use.

[0003] A Chinese patent with the publication number CN212950474U has been searched and disclosed a positioning structure of a car USB injection molding bracket, including a connecting arm and a mounting hole. The top surface of the car USB bracket matches and abuts against the shape of the mounting hole. A welding hole for positioning when welding with the car seat guard is opened on the connecting arm. The edge of the welding hole is integrally provided with a positioning welding rib. A positioning column matching and plugging with the welding hole is protruding on the inner wall surface of the car seat guard. The top of the positioning column is in the shape of a cover that is buckled with the positioning welding rib. The positioning column is inserted into the welding hole so that the top of the positioning column and the positioning welding rib are positioned and welded together. The utility model adds a positioning structure to the car USB bracket. It not only satisfies the ease of assembly, but also satisfies the positioning function of welding. It meets the requirements of product quality.

[0004] However, during the processing and installation of the automobile threshold guard plate, the positioning structure of the automobile USB injection molding bracket is not accurate and stable enough for the positioning angle of the threshold guard plate, which is not convenient for processing and installation operations, and whether continuous processing is possible when processing different surfaces affects work efficiency.
