Vehicle Compressor Layout for Front-Rear Collision Load Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressor installation structures in vehicles do not effectively suppress collision loads in the vehicle front-rear direction, which can impact compressors and other components.
Innovation Solution
A compressor installation structure where the battery is positioned at the vehicle's lower side of the cabin, the power unit is placed at the front-rear direction beside the battery, and the compressors are located at the front-rear direction beside both the battery and power unit, with optional configurations including paired compressors and specific tube arrangements for cleaning and air conditioning systems, supported by a frame structure that spans the vehicle width.

Engineering Contradiction Analysis
1Object-affected harmful factors
If the compressor is installed in the vehicle without protective positioning, then the device complexity is reduced, but the collision load from front-rear impacts directly affects the compressor
Solution Approach 1:
The patent positions the compressor in a specific spatial location that is rearward of the power unit and laterally offset from the battery, creating a three-dimensional protective arrangement. This spatial configuration uses the vehicle's existing component layout to shield the compressor from front-rear collision loads without adding separate protective structures.
Solution Approach 2:
The power unit serves as an intermediary protective element positioned between the potential collision source and the compressor. The battery also acts as a protective barrier on one side, utilizing existing heavy components to absorb or redirect collision forces before they reach the compressor.
2Object-affected harmful factors
If protective structures are added around the compressor, then the collision load protection is improved, but the device complexity increases
Solution Approach 1:
The patent makes the existing battery and power unit serve dual functions: their primary functions (energy storage and power generation) plus a secondary protective function of shielding the compressor from collision loads. This eliminates the need for dedicated protective structures while maintaining comprehensive protection.
Solution Approach 2:
The compressor protection is achieved through the self-arranged spatial positioning of components within the vehicle. The existing component layout naturally creates protective barriers without requiring additional active protection systems or complex installation structures.

AI summary
A compressor installation structure for a vehicle has: a battery that is disposed at a vehicle lower side of a floor portion of a vehicle cabin; a power unit that is disposed at one side in a vehicle front-rear direction with respect to the battery; and a compressor that is configured to be driven by electric power supplied thereto from the battery, and that is disposed at one side in the vehicle front-rear direction with respect to the battery, and that is disposed at another side in a vehicle front-rear direction with respect to the power unit.
