Elastic Spring Battery Mount for Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Saddle-type electric vehicles experience significant up and down movement, causing the battery to shake, which transmits discomfort to the rider and applies shocks to the battery during travel, and existing methods to secure the battery complicate charging and induce additional shocks.
Innovation Solution
A saddle-type electric vehicle design featuring a battery accommodating portion with lower and upper springs that elastically support the battery, preventing shake transmission and reducing shock, along with an adjuster mechanism to normalize spring forces and improve accessibility for easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the battery is fixed to the vehicle body by bolts, then the battery shaking is prevented, but the battery removal work is complicated and additional shocks are induced to the battery
Solution Approach 1:
The battery fixing structure is segmented into multiple independent spring elements (front spring, rear spring, left spring, right spring) that can independently support and cushion the battery. This segmentation allows the battery to be firmly held during travel while enabling easy removal by simply overcoming the spring force, without requiring complex bolted connections
Solution Approach 2:
Spring elements are installed beforehand between the battery and vehicle body to provide continuous elastic cushioning. This beforehand cushioning prevents battery shaking during travel while allowing easy battery removal, as the springs naturally decompress when the battery is lifted, eliminating the need for complex unfastening operations
2Object-affected harmful factors
If the battery is fixed to the vehicle body by bolts, then the battery shaking is prevented, but shocks are induced to the battery when the vehicle travels
Solution Approach 1:
Spring elements are pre-installed between the battery and vehicle body to provide continuous elastic cushioning. These springs absorb and attenuate shocks from vehicle travel before they reach the battery, preventing both shaking and impact damage while maintaining secure battery positioning
Solution Approach 2:
The fixing structure transitions from rigid bolt connections to elastic spring elements, changing the mechanical parameter from rigid fixation to flexible support. This parameter change allows the battery to be firmly held during travel while naturally absorbing shocks through elastic deformation, preventing shock transmission to the battery
3Ease of operation
If the battery is not fixed, then the battery removal is simplified, but the battery shakes relative to the vehicle body causing rider discomfort
Solution Approach 1:
The battery support structure uses multiple segmented spring elements positioned at different locations (front, rear, left, right) to provide comprehensive vibration damping. This segmented approach effectively suppresses battery shaking in multiple directions, preventing rider discomfort while maintaining simple battery removal capability
Solution Approach 2:
The battery support transitions from rigid fixation to elastic spring support, changing the mechanical parameter from rigid to flexible. This parameter change eliminates battery shaking that causes rider discomfort while allowing easy battery removal, as the springs naturally release when the battery is lifted
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively prevents battery shake from being transmitted to the rider, reduces shock applied to the battery, and simplifies battery removal and charging by using elastic support and an adjuster mechanism to manage spring forces.
Implementation Method 1
the lower spring supports the lower surface of the battery and is allowed to elastically deform in an extension direction and a compression direction
Implementation Method 2
the upper spring presses the upper surface of the battery and is allowed to elastically deform in an extension direction and a compression direction

AI summary
A lower spring (57) for supporting a lower surface of a battery (30) is provided on a bottom portion (55) of a battery case (50). A cover (60) for covering the battery (30) includes an upper spring (61) to catch the battery (30) together with the lower spring (57) in the up and down direction. In a state where the battery (30) is placed in the battery case (50) and the cover (60) closes, the lower spring (57) supports the lower surface of the battery (30) and is allowed to elastically deform in an extension direction and a compression direction and the upper spring (61) presses the upper surface of the battery (30) and is allowed to elastically deform in an extension direction and a compression direction. The above structure can prevent a shake of the battery from being transmitted to a rider when the vehicle is travelling and reduce an impact applied to the batteries.
