Riding Mower Battery Layout for Stable Weight Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current battery-powered riding mowers experience instability due to a rear-heavy weight distribution, leading to potential tipping and reduced efficiency, and have cramped spaces that complicate maintenance of the electronic control system.
Innovation Solution
The battery assembly is positioned centrally between the front and rear wheels, allowing for even load distribution and enhanced stability, with a design that includes a base between the wheels and a tail portion for accommodating the battery and tools, facilitating easier access and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the battery assembly is located at the tail of the mower, then the power supply is sufficient, but the center of gravity shifts to the back causing the front to head up when climbing slopes or starting
Solution Approach 1:
The patent inverts the conventional battery placement location by positioning the battery assembly in the middle of the mower body rather than at the tail. This inversion of the weight distribution arrangement resolves the head-up problem while maintaining sufficient power supply capability.
Solution Approach 2:
The patent uses the battery assembly itself as a counterweight by strategically positioning it in the middle of the mower. This counterbalances the rear-heavy design, preventing the front from heading up during acceleration or slope climbing, thereby improving overall driving stability.
2Stability of the object's composition
If counterweight is added to the front of the mower to move the center of gravity forward, then the head-up problem is solved, but the invalid load increases and work efficiency is reduced
Solution Approach 1:
The patent makes the battery assembly serve dual functions: it provides power supply and simultaneously acts as a counterweight to balance the mower. This eliminates the need for separate counterweight components, reducing invalid load and improving work efficiency while maintaining driving stability.
Solution Approach 2:
The patent extracts the counterweight function from being a separate added component and integrates it into the battery assembly itself. By taking out the need for additional front counterweights and using the existing battery as the balancing element, the design reduces unnecessary load.
3Volume of moving object
If the electronic control system is arranged under the seat, then the space utilization is improved, but it becomes difficult to wire, debug, and maintain the electric control system
Solution Approach 1:
The patent segments the control system into modular components with the control box positioned in the middle of the mower body, separate from the battery assembly. This segmentation allows for easier access and maintenance while maintaining efficient space utilization through strategic component distribution.

AI summary
A riding mower, which comprises a wheel assembly, a body arranged on the wheel assembly and a battery assembly, the wheel assembly has a front wheel assembly provided with a front shaft and a front wheel and a rear wheel assembly provided with a pair of rear shafts and a pair of rear wheels. The battery assembly is mounted on the body, and a gravity center of the battery assembly is located between the front shaft and the rear shafts along a front to back direction. The riding mower of the present invention can enhance the driving stability of the riding mower and further solve the problems of easy head up and low efficiency of the existing riding mower.
