Seal element construction for moving window glass in vehicle door and window sealing system

Abstract

A sealing structure for car window and door sealing system is located between the door sheet metal and window glass with the feature of providing a loading groove (1) at the lower part of the middle wall (5) that matches with the sheet metal rib(7) of the door. By adopting the above mentioned technical plan after adding a loading groove to the current sealing structure, this invention completely solves the easy flanging issue of the contact lip (11) by relying on the match of the groove with the door's sheet metal rib to form an effective anchorage force at the loading groove (1) to stop the ejection of the upper part of the middle wall when the sealing part flanges with stress. And the whole sealing structure can apply the frameless extrusion production process by using the low rigidity EPDM.

Description

technical field [0001] The invention relates to a sealing member structure of a movable window glass in a door and window sealing system of an automobile. Background technique [0002] At present, the profile structure of the sealing member of the moving glass in the existing sealing system of automobile doors and windows, as shown in Figures 1 and 2, when the cross-sectional contact lip 11 is subjected to external force to produce valgus, because the upper part of the middle wall 12 cannot provide effective sealing. The supporting force, the entire profile will take point 13 and point 14 as the center of rotation, and will come out from the door sheet metal from the upper part 12 of the middle wall along the arrow shown in the figure, causing the seal to fail and affect the appearance. [0003] Currently, in order to avoid valgus, it is often necessary to use ultra-high hardness materials for extrusion, which increases the cost of materials and requires higher requirements ...

[0002] At present, the profile structure of the sealing member of the moving glass in the existing sealing system of automobile doors and windows, as shown in Figures 1 and 2, when the cross-sectional contact lip 11 is subjected to external force to produce valgus, because the upper part of the middle wall 12 cannot provide effective sealing. The supporting force, the entire profile will take point 13 and point 14 as the center of rotation, and will come out from the door sheet metal from the upper part 12 of the middle wall along the arrow shown in the figure, causing the seal to fail and affect the appearance

[0003] Existing in order to avoid valgus, it is often necessary to use ultra-high hardness materials to extrude, the cost of materials is increased, and the requirements for extrusion equipment are high, so the production cost is greatly increased
