Description

Technical Field

[0001] The utility model belongs to the field of rear bumper side brackets, and in particular relates to a rear bumper side bracket with a guide surface. Background Art

[0002] The rear bumper of a car is a safety device that absorbs and mitigates external impact and protects the rear of the car body. In order to provide support for the rear bumper and adjust the gap and surface difference between the rear bumper and the body sheet metal, a rear bumper side bracket is provided between the rear bumper and the body sheet metal. The cross-sectional view of the existing rear bumper side bracket 1 is shown in FIG. Figure 4 As shown, it includes a side bracket flange 12 connected to the side bracket body 11 and the bumper flange 22, and the side bracket body 11 and the side bracket flange 12 are connected by a rounded transition. This connection method has a poor tolerance when assembling the rear bumper 2 and the rear bumper side bracket 1 due to the insufficient guiding function. When the rear bumper 2 is molded and demolded, the bumper flange 22 will be pulled by the inner inclined top structure on the mold and buckle inwardly toward the bumper side wall 21. At the same time, the rear bumper 2 itself will shrink and deform, so Figure 4 It can be seen that at this time, the bumper flange 22 is located at the rear end of the rounded corner. The bumper flange 22 is not easy to connect with the side bracket flange 12 along the rounded corner without guidance. The bumper flange 22 needs to be manually bent outward so that the bottom end of the bumper flange 22 can slide downward along the rounded corner and connect with the side bracket flange 12. Therefore, the rear bumper 2 and the rear bumper side bracket 1 cannot be quickly installed, which reduces the installation efficiency and wastes installation time. Utility Model Content
