AI Technical Summary
After a car collision, the doors cannot be opened, and the occupants are trapped inside and cannot be rescued in time. Current technology cannot effectively solve this problem.
Design a car door hinge, including a fixing component, a bursting component, a connecting component, and a controller. The controller controls the bursting component to push the connecting component to detach, thereby separating the car door from the car body for easy opening.
In the event of a vehicle collision, the controller activates the explosive mechanism, pushing the connecting parts to detach and quickly opening the vehicle door, reducing dismantling time and facilitating external rescue.
