Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging technologies for new energy automobiles require multiple driving devices to control multiple charging interfaces, leading to a high number of parts and increased manufacturing costs.
Innovation Solution
A linkage device that synchronously controls multiple lock rods using a single driving device through a linkage structure, allowing simultaneous control of two or more actuating mechanisms, reducing the number of parts and manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple driving devices are used to control multiple charging interfaces, then each charging interface can be independently controlled, but the number of parts increases and manufacturing cost increases
Solution Approach 1:
The patent combines multiple driving devices into a single driving device that controls multiple lock rods through a linkage structure. The driving device includes a motor connected to a transmission mechanism that distributes rotational motion to multiple lock rods, reducing the total number of driving devices from multiple to one while maintaining independent control capability through the linkage mechanism
Solution Approach 2:
The single driving device is designed with multi-functionality to control multiple charging interfaces simultaneously. The transmission mechanism within the driving device can selectively engage with different lock rods, allowing one driving device to perform the functions previously requiring multiple separate driving devices
2Ease of operation
If multiple driving devices are used to control multiple lock rods, then each lock rod can be controlled, but the manufacturing cost increases
Solution Approach 1:
The patent merges multiple driving devices into one integrated driving device with a shared motor and transmission system. This consolidation reduces manufacturing costs by purchasing and assembling fewer components while maintaining the capability to control each lock rod independently through the linkage structure
3Adaptability or versatility
If multiple driving devices are used, then each charging interface can be controlled, but the number of parts increases
Solution Approach 1:
The patent combines multiple driving devices and their associated parts into a single integrated driving device. The transmission mechanism includes shared components such as a motor, transmission shaft, and linkage structure that serve multiple lock rods, significantly reducing the total quantity of parts compared to using separate driving devices for each lock rod

AI summary
Disclosed in the present disclosure are a linkage device for synchronously controlling multiple lock rods, a charging device and a motor vehicle. The linkage device comprises a driving device (1) having an output end connected to a linkage structure (2), the linkage structure (2) is connected to at least two lock rods, and the driving device (1) drives, through the linkage structure (2), each of the lock rods to synchronously move. In the present disclosure, a linkage structure is designed, so that one driving device can synchronously control two or more actuating mechanisms through the linkage structure, thereby improving the control precision, and effectively reducing the manufacturing cost and the number of sub-parts.
