However, the disadvantages of the buckle-type outer water-retaining strip are also obvious: this type of outer water-retaining strip is formed by buckling the body and the bright strip, and the body is mainly extruded from an aluminum strip and EPDM. The increase in cost and weight has been criticized by the industry

Embodiment 1
[0018] This embodiment proposes a low-cost, light-weight outer water barrier for automobile door glass.
[0019] like figure 1 , 2 As shown, the outer water retaining strip 1 of the automobile door glass of this embodiment includes a main body 11 and a bright strip 12, and the main body 11 includes a U-shaped skeleton formed by connecting the inner cantilever 111, the outer cantilever 112 and the connecting part in the middle. The opening direction of the skeleton is downward; the upper part of the outer wall of the outer cantilever 112 is provided with a first sealing lip 113, and the lower part of the outer wall of the outer cantilever 112 is provided with a second sealing lip 114, and the length of the first sealing lip 113 is greater than The length of the second sealing lip 114; the body 11 of the first sealing lip 113 is inclined upward, the top surface of the body 11 of the first sealing lip 113 forms a groove-like structure, and the end of the first sealing lip 113 ca...

The invention aims to provide an automobile door glass outer water retaining bar which is low in cost and weight. The automobile door glass outer water retaining bar comprises a bright bar and a body,wherein the body comprises a U-shaped framework formed by connecting an inner cantilever, an outer cantilever and a middle connecting part, and an opening of the U-shaped framework is downward. The water retaining bar is characterized in that the U-shaped framework is made of polypropylene, and the outer wall of the outer cantilever is provided with a sealing lip edge; bright bar clamping groovesare formed in the bottom of the inner cantilever and the connecting part; a protruding bright bar supporting convex part is arranged in the middle of the outer wall of the inner cantilever, and the two ends of the bright bar are embedded into the bright bar clamping grooves; the middle of the bright bar abuts against the bright bar supporting convex part, and therefore the bright bar is fixedly connected with the body. The old design of EPDM and an aluminum strip is abandoned, and the body of the outer water retaining bar is prepared from polypropylene and thermoplastic vulcanized rubber, sothat the cost is reduced, the weight is reduced, and the practicability is good.
Description
technical field [0001] The invention belongs to the technical field of automobile sealing, and in particular relates to an automobile door glass outer water retaining strip. Background technique [0002] As competition in the automotive industry becomes more and more intense, consumers are paying more and more attention to cost and lightweighting. The outer water retaining strip is mainly installed on the outer panel of the car door, which supports the glass to slide up and down, and plays a role in auxiliary sealing and appearance decoration in this position. According to the structural form, the outer water retaining strip is mainly divided into one-piece extrusion type and buckle type. The buckle type has been adopted by European and American enterprises because of its excellent appearance. However, the shortcomings of the snap-on outer water retaining strip are also obvious: this kind of outer water retaining strip is made of the main body and the bright strip, and the ...
