Automobile door glass composite guiding rail and method for producing the same

Abstract

The invention relates to a composite guide rail of vehicle door glass. The composite guide rail comprises a guide rail body for accommodating the edge of vehicle door glass and a sealing strip which is connected with the guide rail body and guides and keeps the vehicle door glass in the middle position of the guide rail body; and the composite guide rail also comprises a bonding layer which is positioned in the connecting part between the sealing strip and the guide rail body and connects the sealing strip and the guide rail body into a whole. The invention also discloses a method for manufacturing the guide rail. The composite guide rail of the vehicle door glass and the method for manufacture the same are implemented and have the following advantages: as the bonding layer is positioned in the connecting part between the guide rail body and the sealing strip, the guide rail body and the sealing strip are combined into a whole; the shearing stress is larger; therefore, the sealing strip is uneasy to fall off from the guide rail body; and the vehicle door glass is also uneasy to insert into the part between the guide rail body and the sealing strip.

Description

technical field [0001] The invention relates to auto parts and a manufacturing method thereof, more specifically, to a composite door glass guide rail and a manufacturing method thereof. Background technique [0002] The door glass guide rail is installed inside the door, and plays the role of limiting and guiding the door glass. At present, most of the door glass guide rails are assembled by including a guide rail body and a rubber sealing strip, usually by inserting a rubber sealing strip (or plastic strip) or bonding a rubber sealing strip (or plastic strip) on the above-mentioned guide rail main body to form a guide rail assembly. Thereby, it plays the role of alleviating the abnormal noise of the glass caused by vibration and protecting the glass. Its structure is as Figure 1 shown. Because the operating environment of the car is relatively harsh, high temperature, vibration and jitter always exist in its use process, and the existing guide rail is assembled by using...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a sealing strip that is not easy to fall off from the main body of the guide rail in view of the defects of the prior art that the above-mentioned sealing strip is easy to fall off from the main body of the guide rail, and the door glass is easily inserted between the main body of the guide rail and the sealing strip. 1. A door glass composite guide rail in which the door glass is not easily inserted between the guide rail main body and the sealing strip and its manufacturing method
