Problems solved by technology
Usually, the small radius of the corner of the rear corner window is avoided by other methods on the sheet metal. Otherwise, the products with the same small radius after finalization often need to be extruded with ultra-high hardness materials, which requires high extrusion equipment. At the same time Material cost is also high
In addition, the problem of eversion of the contact lip is more common in structures made of similar materials

Embodiment Construction
[0009] As shown in Figure 2, the present invention, that is, the sealing structure for fixing the corner of the glass in the automobile door and window sealing system, is interposed between the door sheet metal and the window glass.
[0010] The sealing strip 1 is extruded in the whole range, bent and hot-pressed with a small radius, and the locking lip 2 is injection molded during the shaping process, which can ensure the tight seal between the glass 5 and the sealing lip, and ensure that the contact lip 1 will not eversion.
[0011] Below the middle wall 6 of the sealing structure, an assembly groove 3 capable of fitting with the door sheet metal flange 7 is provided. The groove 3 and the door sheet metal 4 can tightly connect the glass with the seal system, and this structure can ensure that the appearance of the rear quarter window and the sliding glass of the door are consistent.
[0012] The utility model uses the locking lip 2 to ensure the tight sealing between the gl...

The sealing structure of the corner of the fixed glass in the car door and window sealing system, applies the extrusion heat stereotyping method to mold with the features of including a pressure molded clip lip (2) above the contact lip (1) that seals the glass (5) and the contact lip(1). Besides, the lower part of the middle wall (6) has a loading groove (3) to match with the sheet metal rib (7) of the door. Adopting the above mentioned solution, that is, using the clip lip(2) to ensure the tight seal between the glass (5) with the sealing lip, it safeguards the non-flanging of the contact lip(1). Besides, the groove (3) and door sheet metal (4) can connect the glass with sealing system tightly to ensure the consistence of the back corner window and the sliding glass of the door. 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 structure for fixing glass corners in an automobile door and window sealing system. Background technique [0002] As shown in FIG. 1 , in the existing sealing system of automobile doors and windows, the sealing structure of the corner part (that is, the C-pillar) of the fixed glass area is generally shaped by extruding the rear corner window part. Usually, the small radius of the corner of the rear corner window is avoided by other methods on the sheet metal. Otherwise, the products with the same small radius after finalization often need to be extruded with ultra-high hardness materials, which requires high extrusion equipment. At the same time Material costs are also high. In addition, the problem of eversion of the contact lip is more common in structures made of similar materials. Contents of the invention [0003] The present invention aims to provide a sealing structure for fixing glass corners in an automob...
