Battery Lock Hook with Elastic Compression for Universal Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery exchange systems for electric or hybrid vehicles are costly, complex, and unreliable due to the need for multiple locking units and actuation mechanisms, which are not economically viable for different types of batteries and require complex actuation systems, leading to high operational costs and inefficiencies.
Innovation Solution
A system comprising a plurality of locks with hooks that use elastically deformable means and a transmission device actuated by separate tools to securely lock and unlock batteries, allowing for universal, flexible, and cost-effective mounting and dismounting, with a safety mechanism to prevent inadvertent rotation and a design that supports leveling and lifting of the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple locking units with complex actuation mechanisms are used to secure the battery, then the battery can be securely locked and unlocked, but the system becomes costly, complex, and unreliable
Solution Approach 1:
The locking system is divided into multiple independent locking units, each with its own hook and transmission device. These units can be independently actuated by separate tools, allowing secure locking without requiring a complex centralized actuation system. Each unit operates autonomously to secure the battery to the vehicle structure.
Solution Approach 2:
The locking units are designed to be actuated by simple external tools rather than complex integrated actuators. The transmission device converts simple rotational motion from manual or automated tools into the hook's locking motion, eliminating the need for motors, sensors, and control systems within each locking unit.
2Ease of operation
If complex actuation mechanisms with motors and transmission shafts are implemented to control hook movements, then autonomous battery release is achieved, but the cost becomes very high and often prohibitive
Solution Approach 1:
Complex electro-mechanical actuation systems (motors, transmission shafts, sensors) are replaced with a simple mechanical transmission device. This device uses basic mechanical principles - a transmission element that converts rotational motion from simple tools into the hook's locking and release movements, dramatically reducing cost while maintaining functionality.
Solution Approach 2:
The transmission device uses simple, inexpensive mechanical components that can be easily manufactured and replaced if needed. Rather than investing in expensive, complex actuation systems, the design employs basic mechanical elements that achieve the same functional result at a fraction of the cost.
3Adaptability or versatility
If standardized locking systems are used across different vehicle types, then universal battery exchange is enabled, but the system must accommodate various battery types and mounting configurations
Solution Approach 1:
The locking units are designed with universal applicability - the same basic hook and transmission device configuration can be used across different vehicle types and battery configurations. The system achieves versatility through standardized interfaces and the ability to accommodate different mounting locations without requiring fundamentally different locking mechanisms.

AI summary
The invention relates to a system for locking and/or unlocking an object, such as a power battery (10) of a drive engine of an electric or hybrid motor vehicle, under a structure such as a chassis (11) of the vehicle, comprising a plurality of locks (17) ensuring the attachment of the object under the structure. The locks (17) are secured to the object and/or structure and each include a hook (19) configured for drawing the object to the structure by compressing an elastically deformable means (20) inserted between the object and the structure and for supporting the object relative to the structure at the end of the approximation travel, as well as a transmission device (21, 22, 24) driving the hook (19) during the drawing travel and configured such as to be actuated by an actuation tool (12) that is separate from the structure and the object.
