AI Technical Summary
In B-pillar-free vehicles, the traditional sealing structure overlaps the welding positions due to the limitation of the installation point, resulting in air leakage in the body holes and air tightness not meeting the standards.
By adjusting the length of the upper rail cover plate, the welding position between it and the side outer plate is staggered with the position between the upper rail reinforcement plate and the side outer plate, and fixed with spot welding sealant to form a closed cavity to enhance the sealing effect.
It reduces the difficulty of welding, reduces the risk of poor airtightness, and improves the airtightness and sealing effect of the car body.

Abstract
Description
Technical Field
[0001] The utility model relates to a sealing structure, in particular to a side panel sealing structure without a B-pillar upper guide rail. Background Art
[0002] In vehicles without B-pillars, the sealing structure of the traditional sliding door upper rail arrangement is typically welded together from three parts: the side panel, the upper rail reinforcement plate, and the upper rail cover. Spot sealant is applied before welding to achieve a good seal. After welding, PVC weld sealant is applied to the side B-pillar and C-pillar to enhance the seal. Under current designs, due to the lack of a B-pillar, mounting points for the front door stopper and front door latch must be located on the upper rail reinforcement plate. This results in the upper rail reinforcement plate and the upper rail cover being identical in length and welded to the side panel in the same location. Furthermore, these holes must meet the requirements of welding vias and electrophoresis process holes. This results in air leakage through the holes in the vehicle body, resulting in substandard airtightness. Utility Model Content
[0003] In view of the above problems, the present utility model is proposed to provide a side panel without B-pillar upper guide rail sealing structure that overcomes the above problems or at least partially solves the above problems. The length of the upper guide rail sealing plate is adjusted to achieve the staggered welding sealing position between the upper guide rail cover plate and the side panel outer panel and the welding position between the upper guide rail reinforcement plate and the side panel outer panel, thereby reducing the sealing difficulty and achieving a better sealing effect.
[0004] Specifically, the utility model provides a side panel sealing structure without a B-pillar upper guide rail, comprising a side panel outer panel, an upper guide rail cover and an upper guide rail reinforcement plate. The upper guide rail cover and the side panel outer panel are welded and connected, the upper guide rail cover is welded and fixed to the upper end of the upper guide rail reinforcement plate, one end of the upper guide rail cover along the A-pillar direction is welded and fixed to the side panel outer panel, the length of the upper guide rail cover along the A-pillar direction is greater than that of the upper guide rail reinforcement plate, the upper guide rail cover is welded and fixed to the side panel outer panel and the upper guide rail reinforcement plate by spot welding sealant, and forms a closed cavity with the guide rail door when it is closed.
[0005] Optionally, at least two sheet metal holes are opened on the upper guide rail cover.
[0006] Optionally, the sheet metal hole is provided with a plug cover.
[0007] Optionally, structural adhesive is provided between the upper guide rail cover and the side panel to increase strength and sealing performance.
[0008] Optionally, the upper guide rail cover is integrally die-cast.
[0009] Optionally, the upper guide rail reinforcement plate is integrally die-cast.
[0010] The side panel without the B-pillar upper guide rail sealing structure of the present invention achieves the staggering of the welding sealing position between the upper guide rail cover plate and the side panel outer panel and the welding position between the upper guide rail reinforcement plate and the side panel outer panel by lengthening the upper guide rail reinforcement plate, so that a relatively closed cavity is formed after the upper guide rail reinforcement plate, the upper guide rail cover plate and the side panel outer panel are welded, thereby enhancing the sealing effect.
