Method and device for fastening joint corner position of sealing strip of front door of automobile

Abstract

The invention provides a method and a device for fastening a joint corner position of a sealing strip of a front door of an automobile. The problems of deformation and failure are mainly caused by the fact that bottom section barbs of the sealing strip of a ROOF section at the top of the sealing strip of the front door of the automobile are mainly clamped through a section of a guide rail, and an installation and fastening purpose and good waterproof and dustproof sealing performance are achieved; however, near the position of a hinge of the front door, the space is narrow, an adhesive tape is not installed in place and is easy to separate from the guide rail, the sealing strip is pressed and deformed when the door is opened or closed, and an existing sealing effect disappears completely. The technical scheme includes that an inserting sheet is added at the position which is 30mm away from the edge of the guide rail of the ROOF section of the sealing strip of the front door, the inserting sheet is attached to the bottom section of the sealing strip, during assembly, the guide rail is slide in firstly, and then the sealing strip is installed and fastened, and looseness is avoided.

Description

technical field [0001] The invention relates to the field of vehicle body manufacturing, in particular to a method and a device for fastening corners of automobile front door sealing strips. Background technique [0002] The main function of the car door seal is to prevent water, air, noise and dust from intruding into the passenger compartment from the gap between the door and the body when the car is running. At the same time, a good door seal design also has the effect of improving the perceived quality of the door opening and closing. The door sealing strip is mainly made of EPDM rubber parts, and the designed installation and fastening method is to be clamped on the guide rail (such as figure 2 ) and the side wall sheet metal extrusion contact to form a seal; Note: EPDM, EPDM (Ethylene-Propylene-Diene Monomer) is a terpolymer of ethylene, propylene and non-conjugated diene. [0003] The main door seal structure (such as figure 1 ), through the strip guide (such as ...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the problem in the prior art that the door sealing strip is easy to loosen and become deformed and invalid when it is clamped on the guide rail, the present invention provides a method and device for fastening the corner of the automobile front door sealing strip

However, due to the narrow space near the front door hinge, there is often the problem that the rubber strip is not installed in place and easily falls out of the guide rail groove, which in turn causes the sealing strip to be squeezed and deformed when the door is opened and closed, and the original sealing effect is completely invalid.
