Detailed Description

In order to better understand the technical solution of the present invention, the present invention will be described in detail through specific embodiments.

Refer to fig. 1. The utility model discloses a structure is cut to door window extra income, cut body 11 and the outstanding lateral surface of locating extra income and cutting body 11 including extra income for form sealed sealing lip limit 13 with door window glass 14.

The outer water cutting body 11 comprises a framework 15 positioned inside and a sizing material layer 12 wrapped outside the framework 15. Lip 13 is attached to mastic layer 12.

The frame 15 has a rectangular sheet-like shape, and is formed in an inverted U-shaped frame 15 shape by bending two opposite sides of the rectangular shape of the frame 15 downward.

The sizing layer 12 is integrally wrapped on the outer side of the U-shaped framework 15 along the outline of the framework 15, so that the inverted U-shaped outer water cutting body 11 is formed.

The U-shaped opening of the outer water cutting body 11 can be clamped with the car door metal plate 10, so that the outer water cutting body is installed on the car door metal plate 10.

Referring to fig. 2, the planar surface direction structure of the sheet bobbin 15 before bending is shown, and the planar thickness direction structure of the sheet bobbin 15 before bending is shown. The skeleton 15 is a metal mesh type skeleton 15, for example, an aluminum skeleton 15 or a steel skeleton 15.

The grid 151 densely arranged on the frame 15 can be formed by punching a sheet metal material.

Wherein the grids 151 on the skeleton 15 are evenly distributed. Moreover, the grids 151 in any two adjacent rows or columns on the framework 15 are arranged in a staggered manner. Corresponding grids 151 on two arbitrarily spaced rows of grids 151 are all located on the same vertical center line; corresponding grids 151 of two arbitrarily spaced grids 151 are all on the same horizontal center line.

In all the grids 151, when some of the grids 151 are just distributed at the edge of the frame 15, grid openings 152 are formed at the edge of the frame 15, so as to facilitate the overall deformation of the frame 15. That is, the mesh 151 positioned at the outermost portion of the frame 15 is cut at the side portion of the frame 15 to form mesh openings 152.

The mastic layers 12 wrapped around the inner and outer sides of the frame 15 are inserted into the cavities of the mesh 151 by extending each other, thereby connecting the mastic layers 12 on the inner and outer sides of the frame 15. Because the sizing material layer 12 is tightly attached to the surface of the framework 15 and completely permeates into the grids 151 on the framework 15 to form an integral structure, the need of coating the sizing material layer on the surface of the framework to combine with the sizing material layer, which is required by the conventional solid framework structure, is eliminated.

The outer water cutting body 11 has a lip 13 projecting from an outer surface thereof on the side facing the window glass 14. The lip 13 is attached to the outer surface of the layer of mastic 12 on the side of the U-shape of the skeleton 15 facing the window pane 14.

In a preferred embodiment, the grid 151 may include a hexagonal grid 151 of holes. But is not limited thereto.

Further, two of the opposing first angles 153 of the hexagonal apertures are acute angles. Moreover, the connection line between the two opposite first corners 153 is orthogonal to the extrusion direction Y during the outer water cutting, so as to facilitate better deformation of the frame 15.

Refer to fig. 2. In a preferred embodiment, the dimensions on the lattice-type skeleton 15 can be set as follows:

the width A of the framework 15 can be 26-54mm;

the thickness dimension B can be selected (0.57-1.0 mm of aluminum material and 0.4-0.6mm of steel material);

the space size C between any two adjacent grids 151 in the extrusion direction Y can be 3.0-5.0mm;

the opening pitch dimension D of any one of the meshes 151 on the edge portion parallel to the extrusion direction Y may be 0.3 to 2.0mm;

the distance dimension E between two opposing first corners 153 of each grid 151 may be 5.0-11.0mm;

the length dimension F of the two opposing horizontal sides of any one of the cells 151 in the extrusion direction Y may be 2.0-15.0mm.

Wherein the size C and the size D are set in balance. The ratio D/C may be, for example, between 1/6 and 1/3. The rubber material with too small gaps can not be filled and penetrated; too large a void can weaken the rigidity of the carcass 15, resulting in breakage of the extruded strands.

The D/C value is smaller when the aluminum skeleton 15 is used, and larger when the steel skeleton 15 is used (depending on the characteristics of the metal).

It should be understood by those skilled in the art that the above embodiments are only used for illustrating the present invention, and not used as a limitation of the present invention, and that the changes and modifications to the above embodiments are within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
