The water cut framework is usually made of metal, and needs to be formed by rolling and then extruding together with the sealing strip in advance, when the water cut framework is subjected to rolling processing, internal stress is generated inside the framework, stress concentration is generated due to fracture during punching, stress release can be caused at the other end of the punching, and deformation is caused, as shown in fig. 1, fig. 1 shows a sectional structure diagram of a conventional car door external water cut after punching, and a dotted line part in the diagram shows the shape of the water cut framework after deformation. In order to correct the deformation of the water cutting framework caused by the problems, an additional shape correcting tool is required to be configured, and the deformed water cutting framework is corrected after punching, so that the production process is more complicated.

To above-mentioned technical problem, disclose a door extra income in this embodiment and cut, include:

the water cutting framework 10 is arranged on a window frame as a sealing strip 20 supporting framework, the water cutting framework 10 comprises an extension part 110 and a supporting part 120, the supporting part 120 is fixedly connected with the extension part 110, the extension part 110 extends and bends from one end of the supporting part 120 to the lower part of a vehicle door, and the supporting part 120 and the extension part 110 are made of different materials.

In the door outer trim according to the embodiment of the present invention, the trim frame 10 is composed of the extension portion 110 and the support portion 120, and the extension portion 110 and the support portion 120 are made of different materials, so that only a small amount of the support portion 120 can be cut by punching at the time of punching, and deformation of the trim frame 10 due to stress release can be reduced.

Referring to fig. 2, fig. 2 is a schematic cross-sectional structure view of the main body 101 of the framework, specifically, the extension portion 110 of the water-cutting framework 10 is made of a polypropylene material, i.e., a PP material; the support 120 is made of a metal material, wherein the metal may be stainless steel, aluminum alloy, titanium alloy, or the like. The supporting portion 120 is made of metal material because the strength, toughness, corrosion resistance and wear resistance of metal are good, and the water-cut bright strip 30 which is usually extruded integrally can be directly one section of the water-cut frame 10, that is, the bending position of the supporting portion 120 is used as the water-cut bright strip 30, and the water-cut bright strip can provide decoration for the car body because of having metal luster and changing color, luster and the like through various processing modes. The support portion 120 is U-shaped and is fixedly connected to the extension portion 110 by various methods, such as bonding, bolting, or snap-fastening. In the present embodiment, preferably, one end of the supporting portion 120 is embedded into the extending portion 110, and in this way, the supporting portion 120 and the extending portion 110 can be fixed simultaneously during co-extrusion molding, so that additional connection steps are not required, the production steps are optimized, and the fixing of the supporting portion 120 and the extending portion 110 can be tighter. With this arrangement, the use of metal is reduced relative to a structure in which the entire water cutting skeleton 10 is made of metal, and polypropylene (PP) material is used instead. Because the metal material has higher density and higher price, and the polypropylene (PP) material has high strength, toughness and wear resistance, meanwhile, the cost is lower, and the weight is lighter, the polypropylene (PP) material is adopted to replace metal, so that the structural strength is ensured, the cost is reduced, and the light weight of a vehicle body is promoted.

The mounting mode of the end cover 40 and the framework tail end 102 is as follows: the extension 110 of the frame tail 102 is at least partially cut away and the end cap 40 is installed from the cut away position. The cutting position is at the overlapping area of the extension part 110 and the supporting part 120, the extension part 110 below the cutting position of the frame tail end 102 is cut, and the specific cutting position is determined by the size matched with the end cover 40.

Referring to fig. 4 and 5, fig. 4 and 5 are schematic sectional views of the water cut end after being die-cut, wherein fig. 4 isbase:Sub>A schematic sectional view of the outside water cut atbase:Sub>A-base:Sub>A position in fig. 3, and fig. 5 isbase:Sub>A schematic sectional view of the outside water cut atbase:Sub>A-B position in fig. 3. Wherein the length of the cut-out in the vertical section of the water-cut skeleton 10, i.e., the section of the water-cut skeleton 10 in the same line where the extension 110 is connected to the connection portion, is approximately two-thirds to three-fourths, and is selected to maintain the water-cut function of the skeleton tail end 102 while ensuring sufficient space for the end cap 40 to fit. At this time, during punching, the extension portion 110 is cut out substantially, and since the material of the extension portion 110 is polypropylene (PP), internal stress does not exist in the processing process of the material, so that stress release is not caused by punching the extension portion 110, and the water cutting skeleton 10 is not deformed; secondly, although a part of the supporting portion 120 is still cut when the water cutting skeleton 10 is punched, since only a small part of the length of the tail end of the supporting portion 120 is involved, compared with the water cutting punching of the integral steel skeleton, the punching of the water cutting skeleton 10 in this embodiment is less affected, and thus the internal stress is not released, so that the extending end of the supporting portion 120 is not deformed. Therefore, in the present embodiment, after the punching of the frame tail end 102 is completed, the supporting portion 120 of the water-cut frame 10 is not substantially deformed, and no additional step is required to reshape the frame.

With continued reference to fig. 2, the water cut frame 10 of the door trim is generally U-shaped, and in the description of the water cut frame 10, the direction toward the inside of the space surrounded by the U-shape is made inward, and the direction toward the outside of the space surrounded by the U-shape is made outward. The extension part 110 is L-shaped, and the tail end of the extension part is bent inwards, so that the extension part can be fixed with a vehicle door while the strength is improved; the supporting portion 120 is bent to form a smaller U-shape, one end of the supporting portion 120 is embedded into the extending portion 110, an overlapping portion exists between the extending portion 110 and the supporting portion 120 at a portion where the supporting portion 120 is embedded into the extending portion 110, and the length of the overlapping portion is from a connecting position of the base portion of the first mantle 211 and the extending portion 110 to a first bending position of the supporting portion 120. At the end of the support 120 extending outward, the end is also bent inward.

In the present embodiment, the sealing strips 20 are disposed on the water cutting skeleton 10, specifically, the outer sealing strip 210 is disposed on the vertical section of the water cutting skeleton 10, and the inner sealing strip 220 is disposed inside the area surrounded by the bending of the supporting portion 120, and the shape and position arrangement and the function of the sealing strips 20 will be described in detail below.

The outer water cut of the car door further comprises a sealing strip 20, wherein the sealing strip 20 is arranged on the water cut framework 10 and is divided into an outer sealing strip 210 and an inner sealing strip 220. In the description of the present embodiment, the direction of the roof is upward, and the direction of the underbody is downward. The outer sealing strips 210 are arranged on the extension parts 110 of the water cutting framework 10 and extend outwards; the inner sealing strip 220 is arranged on the supporting part 120 of the water cutting skeleton 10 and is positioned in the space formed by inward bending of the supporting part 120. The outer seal strip 210 has a first mantle 211, a second mantle 212, and a first buffering lip, and a second outer buffering lip 214 engaged with the first outer buffering lip 213 is further provided at an end of the first mantle 211. The first mantle 211 and the second mantle 212 are in contact with the window glass, wherein the first mantle 211 and the second mantle 212 both have a mantle base and a mantle end, the mantle base has a shorter length, is connected with the extension 110 of the water cutting framework 10, extends outward approximately perpendicular to the extension 110 of the water cutting framework 10, the cross section of the mantle base is outward reduced from the contact surface with the extension 110, and the mantle end forms an obtuse angle with the mantle base and is obliquely inclined and extends for contacting with the window glass.

A first outer buffer lip 213 is disposed at a position where the supporting portion 120 of the water cutting frame 10 is connected to the extending portion 110, that is, a first corner portion of the tip of the supporting portion 120 of the water cutting frame 10 embedded in the extending portion 110 is provided, the first outer buffer lip 213 is disposed to extend obliquely upward in a direction opposite to the bending direction of the supporting portion 120, a second outer buffer lip 214 is disposed at an end of the first mantle 211, the second outer buffer lip 214 is also disposed to incline obliquely upward in a direction opposite to the first outer buffer lip 213. With this arrangement, when the first and

second flaps

211 and 212 contact the window glass and are pressed, the first flap 211 is pressed and bent, so that the second outer buffer lip 214 is pressed into contact with the first outer buffer lip, and the first and second outer buffer lips cooperate with each other to improve the sealing performance when the door trim contacts the window glass.

And because the contact area of the first outer buffer lip edge 213 and the glass is smaller, when the glass slides and moves relative to the first outer buffer lip edge 213, no noise is generated, so that the effects of noise reduction and protection can be achieved.

On the first mantle 211 and the second mantle 212, flocking layers 230 are disposed from end fillets of the first mantle 211 and the second mantle 212 to corners of bases. With such an arrangement, noise generated when the first and

second mantles

211 and 212 contact with glass and move relatively can be reduced, and sealing performance can be improved. In addition, because the flocking layer 230 wraps the round corners at the end parts of the first mantle 211 and the second mantle 212, the abnormal sound of the glass lifting caused by the soft material, namely the direct contact of the flocking layer 230 and the glass, is avoided, and the use noise is further reduced.

A first inner buffering lip edge 221 is arranged in a space enclosed by the water cutting framework 10, is arranged on the supporting part 120 and extends towards the inner side, and thus when the water cutting framework 10 is extruded, the water cutting framework can play a role in buffering and support the water cutting framework 10 to avoid deformation; the extending end of the supporting portion 120 is provided with a second inner buffer lip 222, and extends outwards, and the extending end of the supporting portion 120 bends inwards in the opposite direction, so that the extending end can abut against the outer plate of the vehicle door, and the sealing and buffering effects are achieved.

In conjunction with the above, when the frame tail end 102 is die cut, the cutting position is located at the connection of the root of the first mantle 211 and the extension 110. That is, when the frame tail end 102 is punched and used for mounting the end cap 40, the first mantle 211, the second mantle 212, the extension portion 110, and the support portion 120 embedded in the extension portion 110 are cut off together; the upper part of the connection position of the end of the first mantle 211 and the extension part 110 may be cut off, that is, more extension parts 110 and the part of the support part 120 of the water cutting skeleton 10 embedded in the extension parts are cut off.

After punching, the end cover 40 is installed in the cut structure part, and the end tip of the punched end part of the support part 120 is abutted against the end cover 40 in the vertical direction, so that the end cover 40 is matched with the water cutting framework 10 to support the water cutting structure in the vertical direction; in the horizontal direction, when the outer side of the water cutting frame 10, that is, the supporting portion 120 is pressed, the first inner buffering lip 221 can abut against the end cover 40 to support the water cutting structure, so that the frame tail end 102 can still support the water cutting structure after being punched, and the stability of the structure is maintained.

In the present embodiment, the door trim is integrally extruded, the trim frame 10 and the weather strip 20 are co-extruded, and the bent portion of the support portion 120 of the trim frame 10 is used as the trim strip 30 during assembly.

As shown in fig. 6, in another embodiment, the door outer trim may also adopt a snap-fit bright strip 30 structure, and fig. 6 is a schematic cross-sectional structure diagram of the door outer trim applied to the snap-fit bright strip structure according to the technical solution of the present application. The fastening bright strip structure is formed by extruding the water cutting frame 10 and the sealing strip 20 together, and then fastening a steel strip as the bright strip 30 on the outer side of the supporting portion 120 of the water cutting frame 10. In this embodiment, on the basis of the above technical solution, one end of the extension portion 110 engaged with the support portion 120 is extended to the bending position of the extended end of the support portion 120, and a first protrusion is disposed on the extension portion 110 beside the first outer buffering lip 213 for fastening with a steel strip to fix the steel strip; the third and fourth outer buffer lips are added on the supporting portion 120 of the water cutting frame 10, wherein the fourth outer buffer lip is used for fastening the bright strip 30 and fixing the bright strip 30.

The technical scheme is that the integral co-extrusion type vehicle door outer water cutting and the buckling bright strip type vehicle door outer water cutting are both applicable, the difference of the two schemes is that the integral co-extrusion type vehicle door outer water cutting and the buckling bright strip type vehicle door outer water cutting adopt the part of the supporting part 120 of the water cutting framework 10 as the water cutting bright strip 30, the buckling bright strip type vehicle door outer water cutting and the buckling bright strip type vehicle door outer water cutting are respectively buckled with a metal bright strip 30 on the water cutting framework 10, but the two can avoid the deformation problem caused by stress release of the water cutting framework 10 after the water cutting end part is punched, the weight is reduced, and the cost is saved.

The above description is only a preferred embodiment of the present application and should not be taken as limiting the present application, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present application should be included in the protection scope of the present application.
