Tailgate Hinge Mounting Structure Without Separate Reinforcements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tailgate hinge mounting structures require separate reinforcements for durability, which complicates the mounting process and increases costs.
Innovation Solution
A tailgate hinge mounting structure that incorporates a rear end module connected to a roof rail and a tailgate hinge, utilizing bracket and rail bolts for a double connection in both the vertical and length directions of the vehicle body, eliminating the need for additional reinforcements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple layers of vehicle body reinforcement are welded to secure mounting strength, then the tailgate hinge mounting strength is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the reinforcement function into the rear end module itself, which is already a structural component of the vehicle body. The rear end module integrates the bracket support function and reinforcement function into a single component, eliminating the need for separate reinforcement pieces. The bracket support hole is directly formed in the rear end module, combining multiple functions (structural support, reinforcement, and mounting) into one integrated component.
Solution Approach 2:
The rear end module serves multiple functions: it provides structural reinforcement, contains the bracket support hole for hinge mounting, and integrates with the roof rail system. This multi-functional design eliminates the need for separate reinforcement components while maintaining or improving mounting strength.
2Strength
If multiple layers of vehicle body reinforcement are welded to secure mounting strength, then the tailgate hinge mounting strength is improved, but the manufacturing cost increases
Solution Approach 1:
By combining the reinforcement function into the existing rear end module, the patent reduces the total number of components that need to be manufactured and assembled. This integration reduces welding operations and material usage, thereby lowering manufacturing costs while maintaining mounting strength.
Solution Approach 2:
The patent extracts the reinforcement function from separate reinforcement pieces and integrates it into the rear end module. This eliminates the need to manufacture and install separate reinforcement components, reducing overall manufacturing complexity and cost.
3Stability of the object's composition
If a separate reinforcement is added to stabilize the tailgate hinge mounting, then the mounting stability is improved, but the device complexity increases
Solution Approach 1:
The stability-providing reinforcement function is merged into the rear end module, which already exists as part of the vehicle body structure. The bracket support hole is directly formed in this integrated module, eliminating the need for separate reinforcement pieces while maintaining mounting stability.
Solution Approach 2:
The patent segments the mounting function by creating a dedicated bracket support hole in the rear end module, separating the hinge mounting function from the general body structure while integrating it into the existing modular rear end design. This reduces overall structural complexity.
