Vehicle Body Structure Layout for Air Pump Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The arrangement of air tanks and air pumps in vehicle trunks occupies space, limits trunk expansion, and generates vibration that affects vehicle stability and riding experience.
Innovation Solution
A vehicle body structure design with longitudinal beams and a cross beam supporting an air pump and air tank positioned at both sides of the central axis, utilizing an adapter bracket and vibration isolation structures to block vibration, and incorporating an expansion portion for trunk space optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the air pump and air tank are arranged in the trunk, then the vibration generated by the air pump affects the vehicle body structure, but arranging them outside the trunk is not feasible
Solution Approach 1:
The patent introduces an adapter bracket as an intermediary component between the air pump and the longitudinal beam. This adapter bracket serves as a mediator that connects the air pump to the vehicle body structure while isolating the vibration source from directly affecting the trunk and vehicle body, thus resolving the contradiction between containing the air pump in the trunk and reducing vibration impact.
2Volume of moving object
If the air pump and air tank occupy trunk space, then the trunk expansion is limited, but they are needed for vehicle operation
Solution Approach 1:
The patent positions the air pump and air tank along the width dimension of the vehicle (left and right sides of the central axis) rather than occupying the length dimension of the trunk. This dimensional arrangement allows the trunk to expand forward and backward while the air pump and air tank are accommodated laterally, thus resolving the contradiction between trunk volume and vehicle operation reliability.
3Device complexity
If the air pump is connected directly to the longitudinal beam, then the structure is simple, but the vibration transmission to the vehicle body is significant
Solution Approach 1:
The adapter bracket serves as a vibration-isolating intermediary between the air pump and the longitudinal beam. It includes mounting portions that connect to both the air pump and the longitudinal beam, while incorporating vibration isolation measures such as rubber cushions or dampers to reduce vibration transmission to the vehicle body structure.
4Adaptability or versatility
If the air pump and air tank are positioned close to the rear suspension, then they adapt to various rear suspension lengths, but the space utilization must be optimized
Solution Approach 1:
The patent positions the air pump and air tank asymmetrically on left and right sides of the vehicle's central axis, rather than symmetrically or in a linear arrangement. This asymmetric lateral placement allows adaptation to different rear suspension lengths while efficiently utilizing the available width-wise space in the trunk area, thus resolving the contradiction between adaptability and space utilization.
