Description

Technical Field

[0001] The utility model belongs to the field of rear bumper brackets, and in particular relates to a rear bumper bracket which is used for constraining flanges on both sides of a rear bumper. 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 and the rear taillight, a rear bumper bracket and a taillight lower bracket are provided between the rear bumper and the body sheet metal. The existing rear bumper bracket can only constrain the flange on the rear bumper and the side of the body panel, but has no constraint ability on the flange on the rear bumper and the side of the body taillight, and can only be constrained by the taillight lower bracket. Therefore, the existing structure has the following problems:

[0003] 1. The rear bumper bracket has a single flange constraint on the rear bumper, which makes the lower bracket of the taillight long and bulky;

[0004] 2. The lengthy lower taillight bracket will weaken the constraint on the rear bumper and the side flange of the taillight, which is not conducive to the control of the surface difference and gap between the rear bumper and the side flange of the taillight.

[0005] 3. Since the lower bracket of the taillight is too long to the edge of the triangular area of ​​the rear bumper, the fixing point of the lower bracket of the taillight is too far away from the end of the lower bracket of the taillight, which makes the lower bracket of the taillight easy to deform and increases the difficulty of assembly and matching. Utility Model Content

[0006] The utility model aims to solve the above-mentioned problem and provides a rear bumper bracket which can simultaneously restrain the side flanges of the rear bumper side panels and the side flanges of the rear bumper taillights. By modifying the matching of the rear bumper bracket and the lower bracket of the taillights, the length of the lower bracket of the taillights is shortened while the restraining force on the flanges on both sides of the rear bumper remains unchanged, so that the fixing point of the lower bracket of the taillights is closer to the end of the lower bracket of the taillights, and therefore it is not easy to deform, thus reducing the difficulty of assembly and matching, and being more conducive to the control of the surface difference and gap between the side flanges of the rear bumper and the taillights of the vehicle body.

[0007] In order to achieve the above-mentioned purpose, the utility model provides a rear bumper bracket for restraining the flanges on both sides of the rear bumper, including a bracket body, wherein the bracket body is a contoured structure similar in shape to the side panel side to the taillight side of the rear bumper, including a side panel connecting end and a taillight connecting end, wherein the side panel connecting end is connected to the side panel side of the rear bumper, and the taillight connecting end is connected to the triangular area on the taillight side of the rear bumper, so that the bumper bracket can restrain the side panel flange on the side panel side and the taillight side flange on the taillight side.

[0008] As a further optimization, the bracket body is surrounded by inwardly bent side walls, and a accommodating cavity is formed on the inner side of the bracket body by connecting the side walls. The side walls are provided with claws at the clamping hole positions relative to the side flange and the taillight side flange. The accommodating cavity is provided with a plurality of connecting columns for connecting to the body sheet metal, and at least one positioning column for positioning the body sheet metal.

[0009] As a further optimization, the side wall between each two adjacent claws and both ends of the side wall are provided with outwardly protruding positioning grooves, which cooperate with the positioning holes on the side flange to support and position the side flange of the rear bumper, and the positioning groove on the taillight side rests on the taillight side flange to support and position the taillight side flange.

[0010] As a further optimization, a plurality of supporting ribs are provided on the side wall opposite to the side panel flange and the taillight side flange.

[0011] As a further optimization, reinforcing ribs are provided between the connecting column and the positioning column, and between the connecting column, the positioning column and the side wall.

[0012] Advantages and beneficial effects of the utility model

[0013] 1. The rear bumper bracket of the utility model is a contoured structure similar in shape to the triangular area from the side panel side to the taillight side of the rear bumper. By connecting the side panel connecting end of the rear bumper bracket to the side panel side of the rear bumper and connecting the taillight connecting end to the taillight side of the rear bumper, the side flange of the rear bumper side panel and the side flange of the rear bumper taillight can be constrained by the rear bumper bracket.

[0014] 2. The utility model modifies the rear bumper bracket and the lower taillight bracket to match each other, thereby shortening the length of the lower taillight bracket while maintaining the constraint force on the flanges on both sides of the rear bumper. Therefore, the lower taillight bracket will not weaken the constraint on the rear bumper and the side flanges of the taillights on the vehicle body, which is beneficial to the control of the surface difference and gap between the rear bumper and the side flanges of the taillights on the vehicle body, and reduces the weight and cost of the lower taillight bracket.

[0015] 3. In the utility model, one end of the rear bumper bracket extends to the taillight side triangular area, so the length of the taillight lower bracket matched therewith is relatively shortened to the rear of the taillight side triangular area, so that the fixing point of the taillight lower bracket is closer to the end of the taillight lower bracket, so it is not easy to deform, reducing the difficulty of assembly and matching, and facilitating the optimization of matching.
