Detachable Battery Module Structure With Waterproof Cart Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power-assisting battery structures face issues such as difficult detachment of rear batteries, requirement for separate charging, and lack of waterproofing and dustproofing, leading to operational inefficiencies and space constraints.
Innovation Solution
A detachment structure featuring structurally identical supports with integrated waterproof and dustproof battery holders, allowing easy battery replacement and simultaneous charging, with a waterproof cover and grip for easy access, and a quick-release transmission system for motor wheels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If two batteries are detachably mounted in front of and behind the driving controller respectively, then the power supply capacity is increased, but the rear battery becomes blocked by the cart and difficult to detach
Solution Approach 1:
The battery system is segmented into two independent battery units that can be separately mounted and detached. Each battery has its own dedicated mounting position and detachment mechanism, allowing independent access and removal without interference from the cart structure or the other battery.
Solution Approach 2:
The battery mounting positions are arranged in different spatial dimensions and orientations. The front battery is mounted in a position accessible from the front, while the rear battery is mounted in a position accessible from the side or top, changing the dimensional approach to access and avoiding blockage by the cart body.
2Quantity of substance
If batteries are detachably mounted separately, then they can be separately charged, but they must be taken out individually which increases operation time
Solution Approach 1:
The two battery units are combined into a single integrated battery assembly that can be installed and removed as one unit. The batteries are electrically connected and mechanically coupled, allowing simultaneous charging when installed, while reducing the number of manual operations required compared to handling batteries separately.
3Ease of operation
If the battery holder is exposed without cover, then access is easy, but it lacks waterproof and dustproof protection
Solution Approach 1:
A waterproof and dustproof cover is provided that encloses the battery holder and batteries. The cover is designed with sealing structures such as gaskets or seals that prevent water and dust penetration while maintaining easy access through simple opening and closing mechanisms.
4Object-affected harmful factors
If a waterproof cover is added to protect the battery holder, then waterproofing and dustproofing are improved, but the structure becomes more complex
Solution Approach 1:
The waterproof cover is designed to serve multiple functions: it provides waterproof and dustproof protection, structures the battery holder compartment, provides mounting surfaces for batteries, and includes integrated sealing structures. This multi-functionality reduces the need for additional separate components.

AI summary
A detachment structure of a power-assisting battery, applicable to a cart, includes a support module, two motor wheel sets, and a battery module. The support module includes two structurally identical supports. One end of each support has a raised element and a dented element. The supports are fitted together because the raised elements engage with the dented elements. Each motor wheel set has an axle and a quick-release transmission connector. The battery module includes a battery holder, driver unit, and replaceable battery. The battery holder has a receiving chamber, waterproof cover, and fixing component. The driver unit includes a driver and a signal port. The battery is disposed in the receiving chamber and has a grip whereby the battery can be pulled by a user. The driver and the battery holder are integrated into the battery module. The fixing component allows the waterproof cover to be locked and unlocked.
