Embodiment 1

[0056] see Figure 1-8 Shown is the schematic diagram of the flat water cutting in the first embodiment.

[0057] Flat water cut 01, including decorative top cover 1, skeleton 2 and lip 3, decorative top cover 1 is used to cover the outer sheet metal 02, skeleton 2 extends from decorative top cover 1, lip 3 extends from decorative top cover 1 and / or The skeleton 2 extends out, the decorative top cover 1 gradually inclines upward from the outside to the inside, and the lip 3 includes a first lip 31, and the first lip 31 starts from the middle section of the bottom surface of the decorative top cover 1 and gradually extends downward and inward. A lip 31 is used to closely match and support the corner of the outer sheet metal 02.

[0058] The flat water cut 01 is a strip-shaped structure, arranged along the front and rear direction of the vehicle body, and is used to connect with the outer sheet metal 02 and the reinforcement plate 04 of the car door to form the outer waistline ...

Embodiment 2

[0085] see Figure 9-15 Shown is the schematic diagram of the door assembly in the second embodiment.

[0086] Such as Figure 10 As shown, the door assembly includes the outer sheet metal 02 and the inner sheet metal 03, and also includes the flat horizontal cut 01 in the first embodiment and its modified example.

[0087] The flat water cut 01 is installed at the waistline position of the outer sheet metal 02 and the reinforcing plate 04, and extends along the front-rear direction of the vehicle body.

[0088] Since the first lip 31 of the flat water cut 01 is obliquely pressed downward against the corner of the outer sheet metal 02, the outer sheet metal 02 exerts a downward and inner pressure, and the force on the outer sheet metal 02 is greater, and the pressing effect is better it is good.

[0089] Further, as figure 1 with Figure 13 As shown, the upper side of the outer sheet metal 02 is provided with a first flange 21 and a second flange 22, the first flange 21 e...

Abstract

The invention discloses a car door assembly, which includes an outer sheet metal and an inner sheet metal, and also includes the flat water cut. The flat water cut includes a decorative top cover, a frame and a lip, and the decorative top cover is used to cover the outer sheet metal. , the skeleton extends from the decorative top cover, the lip extends from the decorative top cover and / or the skeleton, the decorative top cover gradually slopes upward from outside to inside, and the lip includes a first A lip, the first lip starts from the middle section of the bottom surface of the decorative top cover and gradually extends downward and inward, and the first lip is used for tight fit and support with the corner of the outer sheet metal . The present invention can be realized by using the existing welding technology, and has low cost and stable structure.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle door assembly. Background technique [0002] The existing design of water cutting outside the waistline of the vehicle body has the following problems: [0003] 1. The traditional water cutting scheme: the outer sheet metal hemming process and structure lead to a large Z-direction difference in the appearance of the outer water cutting, generally greater than 15mm. The main reason is that its installation structure is restricted by the sheet metal hemming and technology, which cannot meet the high quality of the shape. Feeling "flat" needs, unable to cater to the trend of high-end charm; [0004] 2. Flat water cutting of some high-end brands: it solves the problem of large Z-direction step difference, but the waistline adopts laser welding, which requires a large investment and high cost for the production line. [0005] Therefore, it is necessary to design a car ...
