Electric Snowmobile Frame Battery Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric snowmobiles face increased load on the frame due to heavy components like batteries, which can lead to localized stress and affect vehicle stability and comfort during travel.
Innovation Solution
The electric snowmobile design incorporates a body frame with a shaft support frame, front, and rear frames that distribute the battery's load across multiple points, positioning the battery and electric motor to lower the center of gravity and reduce localized stress, using a housing to protect the battery and disperse its weight across the frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a heavy battery is mounted on the vehicle body, then electric power supply is ensured, but localized load on the frame increases
Solution Approach 1:
The battery support structure is divided into multiple frame components (first frame extending forwardly, second frame extending rearwardly, third frame extending downwardly) that collectively support the battery. This segmentation distributes the battery's weight across multiple attachment points and structural elements, reducing localized stress on any single frame component while ensuring adequate electric power supply.
2Use of energy by moving object
If battery is supported by frame, then electric power supply is provided, but vehicle body stability is affected due to increased load
Solution Approach 1:
The battery support structure extends in multiple spatial dimensions: forwardly (first frame), rearwardly (second frame), and downwardly (third frame). This multi-dimensional configuration distributes the battery load across different spatial axes, improving vehicle body stability by preventing concentrated stress while maintaining electric power supply capability.

AI summary
An electric snowmobile that can reduce a load locally applied to a body frame is provided. The electric snowmobile includes a body frame, a right ski and a left ski, a track mechanism, a steering shaft, an electric motor, and a battery. The body frame includes a shaft support frame that rotatably supports the steering shaft, a front frame that extends forwardly and downwardly from the shaft support frame, and a rear frame that extends rearwardly and downwardly from the shaft support frame. The battery is supported by the front frame and the rear frame such that at least a portion of the battery is disposed in a region formed by a line connecting the front frame, the rear frame, a lower end of the front frame, and a lower end of the rear frame in a side view.
