Description

Technical Field

[0001] This utility model belongs to the field of B-pillarless automotive technology, and more specifically, it relates to a B-pillarless double-door sealing structure. Background Technology

[0002] With the rapid updates and iterations of automobiles, consumers have higher requirements for interior space and ease of getting in and out of the car. This has led to the emergence of pillarless double doors, which make getting in and out of the car much more convenient. These doors eliminate the obstruction caused by the B-pillar (located on the side panel) in traditional double doors, achieving a more convenient entry and exit. However, pillarless double doors place higher demands on the car's sealing and watertightness. Existing pillarless double doors, lacking a B-pillar, face serious challenges to their sealing systems, resulting in poor watertightness and airtightness, frequently leading to problems such as water leakage during heavy rain and excessive wind noise at high speeds.

[0003] Existing technology includes a technology entitled "A Column-less, Unordered Supine Door Structure for Automobiles" with publication number "CN117549727A". This technology relates to a column-less, unordered supine door structure for automobiles, comprising a body shell assembly, a front door assembly, and a rear door assembly. The upper and lower ends of the body shell assembly and the rear end of the rear door are equipped with latches. The front and rear door assemblies are each equipped with a lock body adapted to the corresponding latch. The front and rear door assemblies are independent of each other and are opened independently through their respective latches and lock bodies. A sealing strip for the inner side of the rear door B-pillar is snapped into place at the connection point between the inner door panel and the B-pillar sealing plate of the rear door, and a sealing strip for the outer side of the rear door B-pillar is snapped into place at the flange of the outer door panel. The front door assembly is hinged to the body shell assembly via the front door A-pillar hinge assembly, and the rear door assembly is hinged to the body shell assembly via the upper guide rail hinge assembly, the lower guide rail hinge assembly, and the rear end guide rail hinge assembly. This utility model can achieve uninterrupted opening of the front and rear doors without B-pillars, meeting the needs of front-seat passengers for convenient entry and exit.

[0004] However, this technology does not address the technical issues and solutions of this application. Utility Model Content
