Description

Technical Field

[0001] The utility model belongs to the field of automobile parts, and in particular relates to a front triangular window cover, a frameless door and an automobile. Background Art

[0002] The front triangular window cover is an important component of the frameless car door. The front triangular window cover is usually used for decoration and to reduce the noise inside the car. It is required to have a good appearance, no defects such as warping, uneven gaps, looseness, etc., and it needs to be well sealed. Since the sheet metal structure of the frameless door is relatively weaker than that of the framed door, the installation space of the door triangular area is very limited. Not only the installation positioning of the front triangular window cover must be considered, but also the sealing problem. At the same time, the frameless door provides a small installation area for the front triangular window cover, which is difficult to install and easily causes the end to be warped and loose and the aesthetics are low.

[0003] CN210941299U discloses a frameless door and a car, which describes the positioning and installation structure of the triangular cover plate of the frameless door. The structure has no positioning pins for positioning, and relies on two card edges (i.e., card hooks) for simple positioning by line contact. The card edges with line contact can only suppress the "forward" direction, but cannot limit the "backward" direction. It is necessary to manually press the triangular cover plate and then tighten it. The triangular cover plate will shake back and forth during the tightening process. At the same time, a bolt is used to connect the Y direction, and the other two Y directions are also line contact card edges. When the triangular cover plate shakes back and forth during assembly, the line contact Y direction limit will fail, causing the sharp point on the triangular cover plate to warp, and the appearance and wind noise cannot meet the requirements.
