Description

A frameless car door semi-hidden external water-cut installation structure and car door

Technical field

The invention relates to the field of frameless door installation technology, and specifically to a frameless door semi-hidden external water-cut installation structure and a door.

Background technique

With the continuous development of society, people's needs for automobile exterior design have also begun to change. Modern people pay more attention to the appearance beauty and personalization of cars. The appearance lines of cars have evolved from thick to thin, which poses a greater challenge to the width of the water cut outside the door. The traditional car door outer water cut is clamped to the edge surface of the outer panel. The width of the water cut is limited by the edge surface, and the width of the exposed bright surface cannot be compressed. This installation structure cannot solve the problem of the excessive width of the exposed bright surface of the water cut.

For this reason, the existing technology proposes to use a semi-hidden external water cut installation structure. As shown in Figure 1, the external water cut is clamped to the outer window frame reinforcing plate 4. The snap-in joint 41 is not restricted by the wrapping, and the external water cut is exposed. The bright surface is not limited by the window sill surface, and the width can be reduced; however, since the clamping stop 41 is below the window sill, holes appear at both ends of the water cut. At the same time, due to the size restrictions of the inner and outer plate edging structures, the outer water cut ends cannot reach the clamp. If the contacts are too far apart, matching problems such as warping and flipping may occur.
