A kind of outer sealing strip of automobile window sill

Abstract

Provided is an automobile windowsill outer side sealing strip (1) which is coordinated with a streamlined automobile body. The automobile windowsill outer side sealing strip (1) comprises a body (2) and a bright strip (3). The body (2) is an extrusion part which is formed by continuous extrusion molding with the same section and cutting, the cross section of the body (2) is in an inverted V shape formed by an automobile outer edge (4) and an automobile inner edge (5), a first protruded lip piece (6) extending slantly upwards is arranged at the V-shaped top end of the body (2), the bright strip (3) adheres to the outer side of the V-shaped automobile outer edge (4) and is a sheet metal stamping part with a bright front (7), a middle section of the bright strip (3) is protruded downwards to form an arc-shaped protruded part (8), the upper edge and the lower edge of the bright strip (3) are respectively bent towards the back of the bright strip (3), an upper folding edge (9) is formed by the whole upper edge, and a lower folding edge (10) is formed by a left section and a right section except the arc-shaped protruded part (8). The first protruded lip piece (6) is clamped into the upper folding edge (9), and the bottom end of the automobile outer edge (4) of the body (2) is clamped into the lower folding edge (10).

Description

technical field [0001] The invention relates to an outer sealing strip of an automobile window sill, in particular to an outer sealing strip of an automobile window sill with a streamlined appearance surface. Background technique [0002] The outer sealing strip of the car window sill is also called the outer water cut. 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 the most important sealing strip in the automotive sealing system. one. Generally, the section of the body of this sealing strip is roughly in an inverted V shape, and a raised lip is provided along its length. The raised lip is generally made of organic elastic materials, and a flocking layer is pasted on the lip that is close to the window lift glass. . Since the outer sealing strip of the window sill is exposed on the outer side of the window, it is not only a seali...

AI Technical Summary

Problems solved by technology

At present, the outer sealing strips of window sills are formed by continuous heating and extrusion of organic elastic materials, and the manufacturing efficiency is very high; in order to increase its rigidity, the body of the sealing strip is generally equipped with a metal skeleton, which is a metal thin strip processed by rolling to make its cross section After changing from a straight shape to an inverted V shape, it passes through the extrusion die, and the organic elastic material is heated and adsorbed on the surface of the metal skeleton in the extrusion die; in order to improve the appearance of the sealing strip, many mid-to-high-end models currently use it A thin metal strip with a bright surface is used as the skeleton, and the bright surface is used as the exposed surface of the sealing strip, such as disclosed in Chinese patent document CN102442184A; this sealing strip has a bright appearance, but the sealing strip is installed on the There is a strip of equal width on the car, which is not in harmony with the streamlined body
