Abstract

A sliding groove for car glass comprises a bent corner and straight strips on end faces of two edges of the bent corner. The sliding groove is characterized in that the bent corner is made of thermoplastic vulcanizate (TPV), the straight strips are made of ethylene propylene diene terpolymer (EPDM) rubber, and the bent corner and the straight strips are composited. The bent corner and the straight strips adopt a separated structure, and the bent corner is made of TPV, so the friction coefficient is small and car window glass is convenient to slide. The sliding groove for the car glass is long in service life, simple in process, easy to manufacture and low in production cost, and paint spraying and flocking are not required. Usage amount of the EPDM rubber is reduced, emitted harmful gas is little, the bent corner can be recycled due to the fact that the bent corner adopts the TPV, and environment protection is benefited. The bent corner is made of the TPV, so the total weight of the sliding groove for the car glass is lowered.

Description

Automobile glass chute

Technical field

The utility model relates to a kind of automobile sealing member, particularly a kind of automobile glass chute.

Background technology

Existing automobile glass chute is made of bent angle, two straight flanges linking to each other with bent angle, and described bent angle and straight flange are integrated and material is ethylene propylene diene rubber.During use, the driver and conductor controls vehicle window and slides to realize the vehicle window unlatching, closes along Glass Run; When vehicle window was closed, Glass Run played sealing function.The problem that this integrative-structure Glass Run exists is: 1, its corner easy-weathering or aging under the ultraviolet ray irradiation, for prolonging the service life of Glass Run, need Glass Run is sprayed or flocking, and complex process, processing cost is high.2, the ethylene propylene diene rubber friction coefficient is high, is unfavorable for glass slides.3, ethylene propylene diene rubber can discharge a large amount of pernicious gases in process of production, and cannot reclaim, and is unfavorable for environmental protection.4, the ethylene propylene diene rubber quality is large, can increase the overall weight of automobile glass chute.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of easy manufacturing, processing cost is low, can make glass slides smooth and easy, is beneficial to environmental protection, the automobile glass chute that quality is light.

The utility model is achieved in that

A kind of automobile glass chute comprises bent angle and is positioned at vertical bar on two limit end faces of bent angle that its special character is: the material of described bent angle is TPV, and the material of described vertical bar is ethylene propylene diene rubber, and bent angle and vertical bar are combined with each other.

The beneficial effects of the utility model are:

1, because bent angle and vertical bar adopt Split type structure, bent angle adopts TPV, and friction coefficient is little, is convenient to glass for vehicle window and slides.

2, the whole service life of automobile glass chute is long, and need not automobile glass chute is sprayed paint or flocking, and technique is simple, easily manufacturing, and productive costs is low.

3, reduce the use amount of ethylene propylene diene rubber, discharged pernicious gas few, and recyclable behind the bent angle employing TPV, thus be conducive to environmental protection.

4, because bent angle partly adopts TPV, reduced the total mass of automobile glass chute.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the connecting portion schematic diagram of bent angle and vertical bar among Fig. 1.

Among the figure: bent angle 1, vertical bar 2.

The specific embodiment

As shown in the figure, this automobile glass chute comprises bent angle 1 and is located at vertical bar 2 on the end face on two limits of bent angle 1, and the material of described bent angle 1 is TPV, and the material of described vertical bar 2 is ethylene propylene diene rubber, described bent angle 1, vertical bar 2 are combined with each other by the injection moulding mode, and its junction is the district of dissolving each other.

Claims

1. automobile glass chute comprises bent angle and is positioned at vertical bar on two limit end faces of bent angle that it is characterized in that: the material of described bent angle is TPV, and the material of described vertical bar is ethylene propylene diene rubber, and bent angle and vertical bar are combined with each other.
