Automobile sunroof guide rail with buffering and noise reduction structure
By designing a three-dimensional grid structure of buffer grooves and extension grooves on the car sunroof guide rail, combined with rubber pads and protrusions, the problem of poor buffering and noise reduction effect of existing car sunroof guide rails is solved, achieving better buffering and noise reduction effect and vibration resistance.

AI Technical Summary
Existing automotive sunroof rails are not effective at buffering and reducing noise, especially since there is hard contact between the mounting plate and the vehicle frame, which leads to vibration transmission and friction noise problems.
The design employs a three-dimensional mesh structure with buffer grooves and extension grooves, combined with main rubber pads and extension rubber pads, to form a double elastic deformation to reduce the contact area between the mounting plate and the frame. The raised part and rubber ring isolate the metal contact between the bolt and the mounting plate, eliminating high-frequency friction noise.
It effectively reduces the contact area between the mounting plate and the frame, blocks the vibration transmission path, improves the buffering and noise reduction effect, eliminates high-frequency friction noise, and improves the mounting plate's resistance to horizontal impact.
