AI Technical Summary
Existing vehicle sunroofs are prone to wind noise and leakage risks when driving at high speeds due to increased wind pressure and poor sealing. Traditional fixed elastic sealing strips are insufficient to meet the sealing requirements.
A closed-loop air pressure control system consisting of a miniature air pump, air duct, support airbag, and pressure sensor dynamically adjusts the clamping force of the sealing gasket. Combined with the integrated structure of the mounting frame and fixed guide rail, and the integrated structure of the mountain-shaped fixing strip and the sunroof body, adaptive sealing is achieved.
It significantly improves the dynamic sealing performance of the sunroof, reduces wind noise, prevents leakage, ensures structural stability and passenger comfort, and avoids loose connections and structural deformation.

Abstract
Claims
1. A vehicle sunroof assembly of high structural stability comprising a mounting frame (1) and a sunroof body (2), characterized in that: Two fixed guide rails (3) are fixedly connected to both sides of the upper surface of the mounting frame (1). The fixed guide rails (3) have a mountain-shaped guide groove (4) inside. Two mountain-shaped fixing strips (10) are fixedly connected to both sides of the lower surface of the sunroof body (2). The mountain-shaped fixing strips (10) are slidably arranged inside the mountain-shaped guide groove (4). A support airbag (5) is fixedly connected to the inner surface of the mountain-shaped guide groove (4). A sealing gasket (6) is fixedly connected to the outer surface of the support airbag (5).
2. The high structural stability vehicle sunroof assembly of claim 1, wherein: The outer surface of the mounting frame (1) is provided with a micro air pump (8), and the outer surface of the micro air pump (8) is fixedly connected with an air guide tube (9). The end of the air guide tube (9) away from the micro air pump (8) extends into the interior of the support airbag (5).
3. The high structural stability vehicle sunroof assembly of claim 1, wherein: The cross-sectional profile of the mountain-shaped fixing strip (10) is adapted to the cross-sectional profile of the mountain-shaped guide groove (4).
4. The high structural stability vehicle sunroof assembly of claim 1, wherein: The inner surface of the sealing gasket (6) is in contact with the outer surface of the mountain-shaped fixing strip (10).
5. The high structural stability vehicle sunroof assembly of claim 2, wherein: A pressure sensor (7) is embedded on the outer surface of the sealing gasket (6), and the pressure sensor (7) is electrically connected to the micro air pump (8).
6. The high structural stability vehicle sunroof assembly of claim 1, wherein: The mounting frame (1) and the fixed guide rail (3) are integrally formed, and the sunroof body (2) and the mountain-shaped fixing strip (10) are integrally formed.
