Pivot Mounting Assembly for Vehicle Power Distribution Center
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power distribution centers in vehicles are difficult to assemble and require blind operations, making it challenging to access connections safely and efficiently, and they often cause rattles and noise when mounted.
Innovation Solution
A power distribution center mounting assembly with a housing featuring a locking structure and pivot structures that allows the connection surface to be positioned at varying angles, from 10 to 100 degrees, making it easily accessible during assembly and relocatable to avoid occupant compartment access, while also using rib engagement to prevent rattles and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the power distribution center is mounted with connections facing away from the vehicle compartment, then safety and accessibility are improved, but assembly time and operational difficulty increase due to blind operations
Solution Approach 1:
The power distribution center is designed with a pivotable mounting mechanism that allows the connection surface to be rotated between a first position (facing away from compartment for safety) and a second position (facing toward compartment for assembly). This dynamic repositioning resolves the contradiction by enabling easy assembly when needed while maintaining safety during operation.
Solution Approach 2:
The mounting assembly includes a pre-staged position where the connection surface is inclined at 10-30 degrees from horizontal, providing preliminary accessibility for assembly before final mounting. This preliminary positioning allows connectors to be accessed more easily during assembly while still maintaining the final safe position away from the compartment.
2Stability of the object's composition
If the power distribution center is rigidly mounted to eliminate movement, then stability is improved, but rattles and noise increase due to vibration transmission
Solution Approach 1:
The mounting brackets are designed with elastic members that change their mechanical properties based on vibration frequency and amplitude. During normal operation, the elastic members provide flexible mounting that absorbs vibrations and eliminates rattles. During assembly operations, the same elastic members maintain sufficient stability to hold the power distribution center securely in position.
3Ease of operation
If the connection surface is positioned at a steep angle for accessibility, then ease of assembly is improved, but the power distribution center occupies more space within the vehicle compartment
Solution Approach 1:
Instead of positioning the connection surface at a steep angle that would occupy significant vertical space, the invention uses the pivot mechanism to bring the connection surface into the horizontal dimension during assembly. The connection surface can be accessed from the side rather than requiring vertical clearance, effectively utilizing unused lateral space within the vehicle compartment.

AI summary
A power distribution center mounting assembly for a vehicle includes a power distribution center having a connection surface. The power distribution center also includes a housing having a locking structure formed thereon on at least one side of the housing. The housing also includes a pair of pivot structures disposed on opposing sides of the housing. A pair of pivot brackets are mounted on the vehicle with each of the brackets including a pivot slot formed therein receiving the pivot structures. At least one of the pivot brackets includes corresponding lock slots that releasably engage the locking structure defining a pre staged and a final staged position of the power distribution center. When the power distribution center is in the pre staged position the connection surface is positioned at an inclined angle wherein the connection surface is visible relative to a horizontal plane extending from a bottom of the housing.
