Hybrid Vehicle PCU Mount Wire Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electric vehicle mount structures, high-voltage cables often get caught between components due to movement, leading to potential damage and requiring additional protective measures that increase cost and space usage, with existing solutions not effectively maintaining a necessary gap for protection.
Innovation Solution
A mount structure with a wire-protecting portion, such as a bracket or spacer, is implemented to maintain a specific distance between electric units and other components, preventing cable entrapment by holding the wiring in place and allowing for movement without damage.

Engineering Contradiction Analysis
1Area of stationary object
If components are arranged close together in the engine room, then space utilization is improved, but cables may get caught between components causing damage
Solution Approach 1:
A cable guide member is introduced as an intermediary component between the first and second components. This guide member receives the cable and maintains a predetermined distance between components, preventing cable entrapment while allowing compact arrangement. The guide member acts as a mediator that resolves the conflict between space efficiency and cable protection.
Solution Approach 2:
The invention changes the spatial parameter by establishing a predetermined distance between components through the cable guide member. This distance parameter is carefully controlled to be sufficient for cable protection while minimizing space occupation, thus resolving the contradiction between compactness and safety margins.
2Reliability
If separate protectors are provided for cables, then cable protection is improved, but cost and mounting space increase
Solution Approach 1:
The cable guide member combines multiple functions into a single component: it serves as both a structural element maintaining component spacing and a protective element for cable routing. By merging the spacing function and cable protection function into one component, the need for separate protectors is eliminated, reducing complexity and cost.
Solution Approach 2:
The cable guide member is designed as a multi-functional component that simultaneously maintains predetermined distances between components and provides cable protection. This universal component performs multiple roles that would traditionally require separate parts, thereby reducing overall system complexity and mounting space.

AI summary
A mount structure for an electric unit is a mount structure for a PCU mounted in an engine room of a hybrid vehicle. The mount structure includes a vehicle body, the PCU mounted in the engine room, an engine mounted on the vehicle body and spaced from PCU, a cable connected to the PCU and having a portion positioned between the PCU and the engine, and a wire-protecting portion positioned between the PCU and the engine and keeping the distance between the PCU and the cable and the distance between the engine and the cable at respective distances that are at least distances necessary for wiring protection.
