AI Technical Summary
The existing front door lower hinges are easily deformed due to impact force after frequent use, affecting the normal use of the car door.
A front door lower hinge reinforcement is designed, including a support pad, reinforced outer layer and energy-absorbing connector. The reinforced outer layer is made of aluminum alloy material, and the support pad is made of elastic rubber material. The energy-absorbing connections absorb impact force through the energy-absorbing concave rack, energy-absorbing convex frame and holes.
It effectively improves the resistance of the front door hinge to small impact force, and when the impact force is greater than a certain degree, energy is absorbed through the energy-absorbing connector, further improving the impact resistance of the hinge. At the same time, the design is convenient for subsequent replacement.
