Racing Kart Battery Housing Layout for Clear View and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric traveling vehicles, particularly racing karts, suffer from reduced field of view and stability due to the placement of batteries on the sides of the seat, which are affected by relative wind and can obstruct the user's view and disturb travel.
Innovation Solution
The vehicle design positions the battery housing portion rearward of the seat, inclining such that the upper end is further rearward than the lower end, overlapping the seat in the rear view, and is symmetrical to the vehicle's center line, reducing wind drag and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If batteries are mounted sideways in the vehicle body, then the traveling vehicle can be equipped with power supply, but a large amount of relative wind hits the batteries during traveling, disturbing the traveling stability
Solution Approach 1:
The battery housing portion is positioned to overlap the seat in the rear view direction, transitioning from a side-mounted configuration to a rear-positioned configuration that utilizes the vertical and depth dimensions of the vehicle body. This dimensional repositioning removes the batteries from the direct path of relative wind, eliminating wind interference while preserving power supply functionality.
Solution Approach 2:
The battery housing portion is designed with an inclined configuration where the upper end portion is positioned further rearward than the lower end portion. This asymmetric inclination optimizes the positioning of the batteries within the vehicle body, allowing them to be rearward-positioned without blocking the user's side view while maintaining structural integrity and power supply capability.
2Duration of action of moving object
If a large-sized battery is mounted to drive the traveling vehicle for a long time, then the power supply duration is extended, but the battery may block the side view of the user sitting on the seat
Solution Approach 1:
The battery housing is positioned to overlap the seat when viewed from the rear, utilizing the depth dimension of the vehicle body rather than occupying side space. This repositioning allows large-capacity batteries to be installed without interfering with the user's side view, as the batteries are located in the rear portion of the vehicle body behind the seat plane.
Solution Approach 2:
The seat structure serves as an intermediary spatial reference, with the battery housing positioned to overlap the seat in rear view. This arrangement uses the seat's position as a mediator to define the optimal location for the battery housing, ensuring that large batteries can be mounted without blocking the user's side view while maintaining adequate power supply duration.
3Stability of the object's composition
If the battery housing portion is positioned rearward of the seat, then wind interference is reduced, but the battery access may become more difficult
Solution Approach 1:
The battery housing portion is designed with an inclined configuration where the upper end is positioned further rearward than the lower end. This preliminary design consideration facilitates easier battery access by creating a natural inclination that aligns with the user's approach direction, allowing batteries to be removed from the rear without excessive difficulty despite the rearward positioning.

AI summary
A racing kart that is a travel vehicle includes a car body equipped with a seat on which a user can be seated; and a plurality of wheels which are provided to the car body. The seat is configured such that a seating face thereof is positioned lower than the top of the wheels. The car body is provided with a battery housing which is for storing a battery therein and is disposed at the rear of the seat and at a position overlapping at least a part of the seat in a rear view of the car body. The battery housing is slanted such that an upper end thereof is positioned more rearward than a lower end thereof.
