Adjustable Bracket for Vehicle Bumper Clearance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle bumper brackets are difficult to adjust separately for optimal clearance between the bumper skin and lights due to their one-piece structure, which limits their ability to deform and adjust independently, compromising the matching and supporting functions.
Innovation Solution
An adjustable bracket system comprising a fixed bracket connected between the rear bumper and the vehicle body, and an adjusting bracket connected between the fixed bracket and the taillight, with vertically slidable connecting means and position-limiting bosses, allowing for flexible adjustment and secure mounting using self-tapping screws and plastic nut seats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the bracket is made into a one-piece structure to increase strength and ensuring the supporting effect, then the strength and supporting effect is improved, but the adjustability of the bracket is worsened
Solution Approach 1:
The bracket is divided into two separate parts: a fixed bracket and an adjusting bracket. The fixed bracket provides structural strength and support, while the adjusting bracket enables independent adjustment of the bumper position. This segmentation allows each part to perform its specific function optimally without compromising the other.
2Ease of manufacture
If the bracket is made into a one-piece structure, then the manufacturing simplicity is improved, but the independent adjustability of bracket parts is worsened
Solution Approach 1:
The bracket system is segmented into a fixed bracket and an adjusting bracket that can be manufactured separately and then assembled together. This allows each component to be optimized for its specific function while maintaining manufacturing efficiency through standardized connection structures.
3Measurement precision
If the adjusting bracket is vertically moved to control clearance, then the clearance control precision is improved, but the installation complexity is worsened
Solution Approach 1:
A connection structure with vertically elongate openings acts as an intermediary between the fixed bracket and the adjusting bracket. This intermediary structure guides the vertical movement of the adjusting bracket and provides a simple yet effective mechanism for controlling clearance without requiring complex adjustment devices.

AI summary
An adjustable bracket for installation of a vehicle bumper on a body of a vehicle is provided. The bracket is configured to be connected to the body to support the bumper, characterized in that the bracket comprises a fixed bracket (A) and an adjusting bracket (B), wherein the bracket comprises a movable connection between the fixed bracket (A) and the adjusting bracket (B), which allows the adjusting bracket (B) to have a translational movement in the vertical direction (Z) of the vehicle with respect to the fixed bracket (A), and wherein the adjusting bracket (B) is provided at its top with position-limiting means (1) which can abut against a light (2) of the vehicle, and wherein the fixed bracket (A) and the adjusting bracket (B) are both provided with a mounting structure (31, 32, 33) fastened to the same body. The adjustable bracket enables the bumper to be vertically positioned by the adjusting bracket, which controls the matching clearance between the bumper and the light, thereby effectively reducing the risks of uneven match between the light and the bumper.
