Example Embodiment

[0042] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0043] A method for fastening a corner of a sealing strip of an automobile front door, comprising the following steps:

[0044] The upper half of the sealing strip of the front door is set at a position of 20mm to 40mm (preferably 30mm) close to the edge of the guide rail, the insertion piece is arranged at the bottom of the sealing strip, and the width of the insertion piece is smaller than the width of the stamping-type snap-on guide rail, so that the The insert can slide freely in the welding guide rail;

[0045] When assembling, first slide the insert into the guide rail, and then install and tighten the sealing strip.

[0046] The thickness of the insert is 0.5 mm to 3 mm, preferably the thickness of the insert is 1 mm to 1.2 mm. The length of the insert is 15mm to 35mm, preferably the length of the insert is 20mm to 25mm. The material of...

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 ...
