Split type outer water cutting structure and vehicle

Abstract

The invention discloses a split type outer water cutting structure which comprises a metal framework and a water cutting body, the water cutting body comprises a sealing lip and an upper lip which are connected with the metal framework in a split mode, the metal framework is fixedly connected with an automobile door outer plate, and the sealing lip abuts against automobile door glass. The structure of the external water cutting is designed into a split type, all parts in the metal framework and the water cutting body can be independently extruded and formed, the problem of repeated adjustment caused by composite co-extrusion is solved, a steel belt is omitted, the product stability and the manufacturing efficiency are improved, the manufacturing process is accelerated, the weight is reduced, and when internal accessories of the external water cutting are damaged, the external water cutting is convenient to carry. Damaged accessories can be replaced in a targeted mode, the whole outer water cutting structure does not need to be discarded, and cost can be reduced. In addition, the connecting structure of the metal framework and the water cutting body is designed, and the stability of the whole outer water cutting structure can be improved.

Description

technical field [0001] The invention relates to the technical field of water cutting outside a car door, and more particularly relates to a split type water cutting structure and a vehicle. Background technique [0002] The outer water cutout of the car door is used for door decoration, glass defrosting, water removal, dust removal, and a part for clamping the glass assembly. The traditional external water cut structure such as Figure 4 As shown, metal skeleton 1 and water-cutting body 2 are compositely co-extruded. Among them, metal skeleton 1 is mostly aluminum alloy, and water-cutting body is made of EPDM material. In addition, water-cutting body 2 is often set to improve the stability of water-cutting body Therefore, the traditional outer water-cutting structure is actually formed by compound co-extrusion of three materials; however, the shrinkage rates of different materials are inconsistent, and the product stability is poor; the sealing lip 22 is arranged between the...
