AI Technical Summary
Existing car door hinges lack a limiting function, causing the doors to close automatically under gravity or slight touch, affecting the stability and safety of the doors.
A car door hinge with a limiting function was designed. By setting a slot and a pin structure on the connecting plate, and using the cooperation of spring and fixing pin, the door can be limited and fixed to prevent it from closing automatically.
It effectively prevents the car door from closing automatically after being opened, maintains a fixed limit at a specific angle, provides sufficient support, simplifies installation and replacement, and reduces costs.
