Battery Support Structure for Motorcycle with Side Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery support structures for saddle-type vehicles require complex and time-consuming processes for battery and electrical component attachment/detachment, with limited storage capacity and increased weight due to unnecessary components like tool box bands.
Innovation Solution
A battery support structure where the battery case is aligned with the vehicle-width direction, featuring a side opening for detachable battery attachment, integrated storage for tools, and a reinforced design that eliminates the need for additional holding bands by using the battery case and tool box to prevent battery movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a battery support structure is provided in a vehicle body frame of a saddle-type vehicle, then the battery is securely supported and protected, but the overall vehicle weight increases
Solution Approach 1:
The battery support structure is divided into multiple modular components including left and right side support portions, front and rear support portions, and cushioning elements. This segmentation allows for optimized weight distribution while maintaining structural integrity and support reliability for the battery assembly.
Solution Approach 2:
The battery support structure utilizes composite construction combining rigid support portions (made from high-strength materials) with flexible cushioning portions (made from elastic or foam materials). This composite approach provides both structural support and shock absorption, improving reliability while minimizing weight compared to using solely rigid materials.
2Object-affected harmful factors
If the battery support structure includes cushioning portions made of elastic material or foam, then shock absorption and vibration reduction are improved, but the device complexity increases
Solution Approach 1:
The cushioning portions are integrated directly into the battery support structure, merging the support function and shock absorption function into a single unified component. This eliminates the need for separate mounting brackets and cushioning elements, reducing device complexity while maintaining vibration reduction effectiveness.
Solution Approach 2:
The support portions serve multiple functions simultaneously: they provide structural support for the battery, act as mounting points for securing the battery, and incorporate cushioning portions for shock absorption. This multi-functionality reduces the number of separate components needed, simplifying the overall device complexity.

AI summary
[Problem] There is provided a battery support structure for a saddle-type vehicle that allows a battery of a motorcycle to be easily attached to or detached from a battery case in a vehicle-width direction, and that eliminates the need for a special member to fix the battery. [Solution] A tool box 13 is disposed on the rear side of the crank case 11 and below the main frame 7, and a battery case 16 is disposed adjacent to the tool box 13 such that the longitudinal direction of the battery case 16 is equal to the vehicle-width direction. On the left side of the battery case 16, a side opening 16a is formed so as to open toward the left side of the vehicle. The battery 17 is inserted into the battery case 16 through the side opening 16a. Since a box body 30 of the tool box 13 fits in the side opening (16a), protrudes into the battery case 16, and presses and fixes the battery 17, the battery 17 is prevented from moving. An electrical component stay 20 is disposed on the battery case 16 to fix an ECU 18. The electrical component stay 20 covers the ECU 18, and an upper portion, a front portion, and a bottom portion of the battery case 16; and serves as a heat shield plate.
