EV Charger Slide Structure for Brake Cylinder Collision Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electrified vehicles, the charger and brake master cylinder often interfere strongly during collisions, leading to potential damage to the charger's casing.
Innovation Solution
A protective portion with a slide structure featuring an inclined surface is placed between the brake master cylinder and the charger in the front compartment, allowing the charger to slide away from the brake master cylinder during a collision, thus reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the charger is disposed in the front compartment in front of the dash panel, then the charger can be easily accessible and integrated with the vehicle's electrical system, but the charger and brake master cylinder strongly interfere with each other during vehicle collision, causing damage to the charger casing
Solution Approach 1:
A protective portion with a slide structure is introduced as an intermediary element between the charger and brake master cylinder. This protective portion includes an inclined surface that mediates the interaction during collision, allowing the charger to slide away from the brake master cylinder and preventing direct contact that would cause damage.
Solution Approach 2:
The protective portion is designed with a slide structure that enables dynamic movement during collision. The inclined surface allows the charger to move dynamically away from the brake master cylinder when force is applied during impact, rather than remaining fixed and vulnerable to direct interference.
2Volume of moving object
If the charger is positioned close to the brake master cylinder in the front compartment, then space utilization is optimized, but strong interference occurs between the charger and brake master cylinder during collision
Solution Approach 1:
The protective portion serves as a mediator that allows close positioning of the charger to the brake master cylinder for space optimization, while simultaneously preventing direct contact during collision. The slide structure with inclined surface enables the charger to move away when needed, maintaining both compact arrangement and protection.
Solution Approach 2:
The protective portion is pre-positioned between the charger and brake master cylinder to provide beforehand cushioning. The inclined surface is designed to engage during collision, cushioning the impact before it reaches the charger casing and preventing damage.
3Device complexity
If no protective structure is provided between the charger and brake master cylinder, then the device complexity is reduced, but the charger casing is damaged during vehicle collision due to strong interference
Solution Approach 1:
A relatively simple protective portion with slide structure is introduced as an intermediary element. This protective portion provides reliable protection to the charger during collision while adding minimal structural complexity to the front compartment arrangement.
Solution Approach 2:
The protective portion utilizes parameter changes in the form of a slide structure with inclined surface. During normal operation, the protective portion remains stationary, but during collision, the inclined surface enables sliding movement, changing the positional parameter to avoid impact and protect the charger.

AI summary
An electrified vehicle comprising a brake master cylinder included in the brake unit and a charger that converts power supplied from an external power supply into charging power and supplies it to the battery are located in the front compartment. Inside the front compartment, the brake master cylinder is located behind the charger in the longitudinal direction of the vehicle. A protective portion having a slide structure with an inclined surface formed on a portion facing the charger is provided between the brake master cylinder and the charger.
