AI Technical Summary
In existing technologies, the relative rotation of the door and the housing causes the wiring harness to be easily damaged by friction with the bearing, resulting in high replacement costs and long after-sales waiting periods.
The door hinge structure features grooves and mounting slots within the outer shell. The conductive block is pushed by a spring to maintain elastic contact between the contact block and the conductive ring. A multi-layered, stepped conductive ring is fitted around the outer circumference of the hinge, enabling stable transmission of various voltages.
Dynamic electrical connection was achieved during the door rotation process, avoiding wire harness breakage and wear, improving the reliability and service life of electrical connection, and simplifying the assembly process.
