Abstract
Description
Technical Field
[0001] The present invention relates to a frameless door corner window in the area above the waistline of a car door, and in particular to a sealing structure for a frameless door corner window, which can achieve a smooth appearance with the car door glass and the corner window glass being flush, and without the guide rail and the sealing strip being exposed between the car door glass and the corner window glass. Background Art
[0002] With the development of society, consumers have higher and higher requirements for the appearance of cars. Whether the appearance of a car is fashionable has become an important factor affecting consumers' car purchase decisions, and a clean and smooth appearance is an important element of a fashionable appearance.
[0003] Therefore, frameless doors with a smooth and flowing appearance are becoming more and more popular among consumers. With the decrease in the cost of frameless doors, frameless doors are becoming more and more popular. In traditional frameless doors, the appearance in the corner window area above the waistline on the side of the vehicle body is composed of a car door glass, a corner window glass, a guide rail, and a sealing strip. Since the guide rail protrudes from the car door glass and the corner window glass, and the sealing strip is exposed, as shown in Figure 1 , 2, this not only affects the overall sense of the side of the vehicle body, but also affects the smoothness of the side door of the vehicle body.
[0004] Therefore, the exposure of the guide rail and the sealing strip in the corner window area has become an urgent problem to be solved in the industry. Summary of the Invention
[0005] The purpose of the present invention is to propose a new sealing structure for the corner window area of a car door, which can achieve a flush appearance in the corner window area of a frameless door while having a clean design with the guide rail hidden and the sealing strip not exposed.
[0006] To achieve the above purpose, the technical solution of the present invention is: a sealing structure for a frameless door corner window, comprising:
[0007] A car door glass, which is arranged on the side door of a vehicle and opens and closes the opening between the car door and the vehicle body as the glass moves up and down;
[0008] A corner window glass of the car door, which is arranged on the car door of the vehicle, and the outer side surface of the corner window glass is flush with the outer side surface of the car door glass;
[0009] A guide rail, which is arranged on the inner side surface near the outer edge of the corner window glass of the corner window glass of the car door, so that the guide rail is hidden behind the corner window glass of the car door;
[0010] A sealing strip, which is installed in the assembly groove of the front-back opening of the guide rail of the vehicle body, and a third sealing feature is arranged between the outer edge of the car door glass and the outer edge of the corner window glass, at the inner side surface of the car door glass, to block the gap between the car door glass and the corner window glass while hiding the sealing strip.
[0011] Further, the guide rail is adhered to the inner side near the outer edge of the door corner window glass.
[0012] Further, the guide rail is provided with a convex feature extending from the inside to the outside of the vehicle body in the vertical direction, a fixing feature extending in the front-rear direction of the vehicle body, and a supporting feature for installing a sealing strip.
[0013] Further, the first sealing feature and the second sealing feature in the sealing strip are in elastic contact with the inner side of the door glass; a drainage groove is provided between the first sealing feature and the second sealing feature.
[0014] Further, the protruding feature on the sealing strip is inserted into the assembly groove of the guide rail, the second sealing strip lip and the protruding feature of the guide rail are opposed in the front-rear direction of the vehicle body, and the third sealing strip lip and the fixing feature of the guide rail are opposed in the inside-outside direction of the vehicle body, so as to realize the assembly and fixation of the sealing strip in the guide rail.
[0015] Further, the sealing strip is provided with a dense material body for supporting and holding the door glass, and two foaming material bodies in elastic contact with the inner side of the door glass for sealing the gap between the guide rail and the inner side of the door glass.
[0016] Further, a copper wire or a fiber wire is arranged inside the sealing strip to maintain the dimensional stability of the length of the sealing strip.
[0017] Further, the first sealing strip lip on the sealing strip is in interference fit with the lower edge of the door corner window glass to prevent a gap from appearing between the sealing strip and the door corner window glass.
[0018] The beneficial effects of the present invention are as follows:
[0019] A frameless door corner window sealing structure of the present invention can make the appearance of the door glass and the door corner window glass flush and without the guide rail and the sealing strip exposed in the door corner window area, with a smooth, clean and concise appearance, excellent performance and low cost, and has high practical value.
