Hydraulic Hose and Electric Component Mounting Layout for Compact Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing installation structures for electric components and hydraulic hoses in working machines, particularly in small machines like compact excavators, fail to efficiently utilize limited mounting spaces without interference.
Innovation Solution
A plate is fixed to the machine body structure with supports, allowing hydraulic hoses to be arranged between these supports and electric components to be mounted adjacent to the hose arrangement, with a guide member regulating hose movement and a heat shield covering the components to prevent interference and protect from heat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If electric components and hydraulic hoses are installed in limited mounting space of small working machines, then space utilization is improved, but interference between components and hoses occurs
Solution Approach 1:
The plate is divided into distinct functional sections: a hydraulic hose arrangement section for routing hoses and an electric component mounting section for securing components. This segmentation allows each type of component to be organized in its designated area, preventing interference while efficiently utilizing the limited mounting space of small working machines.
2Ease of manufacture
If hydraulic hose is arranged along suspended plates on vehicle body frames, then hose arrangement is simplified, but the structure cannot be applied to vertically arranged hoses
Solution Approach 1:
The plate is designed as a universal mounting structure that can accommodate hydraulic hoses arranged in multiple directions, including vertical arrangements. The plate includes a hydraulic hose arrangement section with guides and clamps that can route hoses both horizontally and vertically, making the structure adaptable to different hose layout requirements while maintaining ease of manufacture.

AI summary
The present invention is provided with: a plate 70 provided while one surface 70a is directed toward the machine body structure of a working machine; a first support 71 and a second support 72, which are raised from the one surface 70a of the plate 70 and which affix the plate 70 to the machine body structure; a hydraulic hose 53h which is routed on and along the one surface 70a of the plate 70; and an electric component 12 mounted on the one surface 70a of the plate 70. The one surface 70a of the plate 70 has a hydraulic hose arrangement section 70H where the hydraulic hose 53h is arranged between the first support 71 and the second support 72, and an electric component mounting section 70E where the electric component 12 is mounted so as to be adjacent to the hydraulic hose arrangement section 70H.
