[0003] At present, the water cutting and the decorative strip on the door frame are respectively fixed on the outer sheet metal of the car door and the door frame. It is necessary to set up fixing mechanisms at specific positions on the outer door sheet metal and the door frame respectively. However, in the design and manufacture of related parts of certain models of cars In the process, it is inevitable that one end of the water cut is not suitable for fixed connection or it is technically difficult to set up a fixing mechanism on the sheet metal outside the door, so it is necessary to find a new connection solution

Embodiment Construction
[0028] The appearance of the connection between the car water cut 1 and the trim strip 2 on the door frame is as follows: figure 1 As shown, the water cut 1 includes a metal skeleton 3 and an organic elastomer extending along the same cross-section as an exposed bright surface. The organic elastomer is molded and attached to the metal skeleton 3 by an extrusion process. The organic elastomer includes a top protruding lip 4 and two strips. The raised lip 5 in the middle is also pasted with a flocking layer for being close to the lift glass of the car window; The sheet 5 and its metal frame 3 are cut off, and the two sides 3A of the metal frame 3 are bent to form a water-cut groove 3B on the back, specifically as Figure 5 shown. The decorative strip 2 on the door frame includes a metal main part 6 that is also an exposed bright surface, and the two sides of the metal main part 6 are bent 6A to form a decorative strip groove 6B on the back, specifically as Figure 9 shown. Th...

An automobile belt line molding and doorframe upper molding end connection structure is characterized in that a belt line molding connector is fixedly arranged at the end of a belt line molding groove, one end of the belt line molding connector serves as a belt line molding end cover, a notch is arranged in the middle of the belt line molding end cover, a protruding rib extending towards the middle of the notch is arranged on one side of the notch, and protrusions are arranged at the ends of the protruding rib so that a recess portion is formed in the middle of the protruding rib. A molding connector is fixedly arranged at the end of a molding groove and comprises a base and a connection portion, a threaded hole connected with an automobile doorframe metal sheet is arranged in the middle of the base, the connection portion comprises an oblique extension portion extending downwards obliquely from the base, the oblique extension portion is provided with an oblique notch, and the protruding rib of the belt line molding connector penetrates through the oblique notch of the molding connector to enable an edge rib of the oblique notch to be clamped in the recess portion of the protruding rib. The automobile belt line molding and doorframe upper molding end connection structure is also capable of achieving fixed connection of a belt line molding without punching on the doorframe metal sheet.
Description
technical field [0001] The invention relates to an end connection structure between an automobile water cut and a decorative strip on a door frame. - Background technique [0002] Water cut is the popular abbreviation of the outer sealing strip of the car window sill. When used, it is close to the window lift glass to block the intrusion of rainwater and achieve the functions of anti-leakage, sound insulation, dustproof, shock absorption and sealing. It is also called the window glass guide groove. One of the most important sealing strips in the automotive sealing system, in order to have a certain rigidity, most of them are embedded in the metal skeleton. Generally, this sealing strip is provided with a protruding lip along its length direction, and the protruding lip is generally made of an organic elastomer material, and a flocking layer is also pasted on the lip that is close to the window lift glass. Because it is exposed on the outside of the car window, it is not on...
