Embodiment Construction

[0028] Below in conjunction with accompanying drawing, the present invention will be further described:

[0029] Figure 1 to Figure 5 Shown is a glass guide rail structure for the rear door of an automobile, which includes a constant-section part 1 , a variable-section part 2 and buckles 3 . The constant cross-section part 1 and the variable cross-section part 2 are combined through an injection molding process, and then fixed to the door sheet metal through a buckle 3 . The constant cross-section part 1 of the glass run channel is compounded with rubber and aluminum skeleton, and the specified cross-section and certain length are obtained by extrusion molding and cutting to length. Then, the constant cross-section part 1 is placed in an injection mold, and through injection molding, a semi-finished product having both a variable cross-section and a constant cross-section is made. The buckle 3 is directly locked on the hole reserved by injection molding of the variable sect...

Abstract

The invention relates to a glass guide rail structure for an automobile rear door. The guide rail structure is characterized by comprising a uniform section part (1), a variable section part (2) and a buckle (3); the uniform section part (1) is formed in an extrusion manner, and the variable section part (2) is formed in an injection manner; during injection molding, the uniform section part (1) is placed in a mold for joint injection molding, and therefore the uniform section part (1) and the variable section part (2) are combined; and the glass guide rail structure is fixed to an automobile door metal plate through the buckle (3). The uniform section part (1) is formed by dense rubber and a metal framework (13) in a composite extrusion manner. The variable section part (2) is formed by dense rubber and a metal insert (24) in a secondary injection molding manner.

Description

technical field [0001] The invention belongs to the technical field of a glass guide rail for a rotary side door of a passenger car, and in particular relates to a glass guide rail structure for a rear door of an automobile. Background technique [0002] With the increasing popularity of passenger cars in China, the competition among major OEMs is becoming more and more fierce, and the emphasis on appearance is constantly increasing. As the main exterior shape, the glass run channel of the side door has also attracted much attention. [0003] According to the structural situation of the door, there are roughly three types of existing passenger car rotary side door glass run channels: 1. The frameless door glass run channel of the integral door inner and outer panels. The glass run channel is fixed by welding the guide rail between the inner and outer panels; 2. Above the outer waistline, the upper section of the rolled door and the door body (inner and outer panels) below t...
