[0032] When the doors of traditional vehicles are closed, the flanges of the side panel metal are usually exposed. During use, mud and sand will accumulate on the flanges of the side panel metal, causing stains and wearing out the paint over time. In addition, the sealing and stability reliability of traditional sealing strips are poor after the doors are closed.

[0033] In view of this, the present invention provides a car rear door wheel cover sealing strip and a vehicle, which mainly solves the problem of mud and sand accumulation between the door sheet metal and the side panel sheet metal, and solves the risk of paint abrasion on the side panel sheet metal; the structure is stable and reliable, the sealing is reliable, and it is not easy to fail after long-term use.

[0034] The specific implementation modes of the present invention will be further explained in detail below through the description of embodiments with reference to the accompanying drawings.

[0035] like Figures 1 to 4 As shown, the automobile rear door wheel cover sealing strip includes a main body 1, a frame 2 and a bubble tube 3; a U-shaped structure is provided on the inner side of the main body, which is clamped on the edge of the door sheet metal through the U-shaped structure; the frame is arranged in the main body to play a supporting role for clamping on the door sheet metal, and the structure is stable and reliable; the bubble tube is connected to the door sheet metal 9 through the main body; when the door is closed, the bubble tube and the side panel sheet metal are attached to form a coating, so that a barrier is formed between the door sheet metal and the side panel sheet metal.

[0036] The bubble tube 3 includes a mudguard portion 301 and a mudguard lip 302, wherein the mudguard portion is connected to the body, and the mudguard lip is connected to one side of the mudguard portion close to the side panel 10, so that when the door panel is closed, the mudguard lip covers the flange of the side panel to improve the sealing performance.

[0037] The mudguard 301 is in an arc shape and bulges toward one side of the door exterior panel 11; a fitting portion is provided on the inner side of the bubble tube, the fitting portion connects the body and the mudguard lip and is arranged in elastic contact with the side panel metal; the interference between the fitting portion and the side panel metal is 2-4mm; the fitting portion is in an arc shape and faces in the opposite direction to the mudguard bulge. The sealing performance of the door panel metal when closed is greatly enhanced by the arc-shaped bulge structure facing in opposite directions inside and outside and the corresponding part.

[0038] The body of the sealing strip includes a connecting portion 101 and an anti-slipping structure, the connecting portion is used to connect the body and the mudguard, and the anti-slipping structure is arranged in the U-shaped structure of the body. A seam-covering lip 5 extends from the inner end of the body, and the seam-covering lip is arranged to fit the door sheet metal.

[0039] The anti-slip tooth structure is a group of teeth arranged side by side and interfering with the edge of the door sheet metal; specifically, the anti-slip tooth structure includes anti-slip outer teeth 6 and anti-slip inner teeth 8, the anti-slip outer teeth are connected to the main body and interfere with the PVC glue 7 of the door sheet metal flange to prevent the wheel cover sealing strip from falling off; the anti-slip inner teeth are connected to the main body and interfere with the door sheet metal flange to prevent the wheel cover sealing strip from falling off, and the structure is stable and reliable.

[0040] The U-shaped structure is provided with a positioning protrusion 4 which fits with the outer side of the door sheet metal and serves to position the wheel cover sealing strip in the Y direction. The positioning protrusions are arranged in a group side by side to improve the structural reliability.

[0041] The automobile rear door wheel cover sealing strip 12 of the present invention has a reasonable structural design. The main body is clamped on the door sheet metal by a U-shaped frame, and the bubble tube is connected to the door sheet metal through the main body. When the door sheet metal is closed, the bubble tube fits the side panel sheet metal and covers the flange of the side panel sheet metal. The structure is stable and reliable, and can effectively block the inside from the outside, achieving a better sealing effect and greatly improving the sealing performance.

[0042] Preferred embodiments of the present invention are:

[0043] The automobile rear door wheel cover sealing strip of the present invention comprises a body 1, a frame 2, and a bubble tube 3; the body 1 is clamped on the door sheet metal 9 by a U-shaped structure; the frame 2 is inside the body 1 and plays a supporting role for clamping on the door sheet metal 9; the bubble tube 3 is connected to the door sheet metal 9 through the body 1.

[0044] like Figure 1 As shown, after the door sheet metal 9 is closed, the bubble tube 3 moves with the main body 1 to cover the flange of the side panel sheet metal 10. The bubble tube 3 covering the flange of the side panel sheet metal 10 can effectively reduce the gap between the side panel sheet metal 10 and the door sheet metal 9 after the door sheet metal 9 is closed, so that the mud and sand outside the door sheet metal 9 are blocked outside the door sheet metal 9 and the side panel sheet metal 10, so that mud and sand will not accumulate on the flange of the side panel sheet metal 10, which greatly enhances the sealing performance of the door sheet metal 9 when it is closed, and ensures that the flange of the side panel sheet metal 10 of the vehicle during use will not be affected by mud and sand to cause paint pollution, thereby greatly improving the comfort experience of the driver and passengers.

[0045] The bubble tube 3 includes a mudguard portion 301 and a mudguard lip 302 , wherein the mudguard portion 301 is connected to the body 1 , and the mudguard lip 302 is along a side of the mudguard portion 301 away from the door sheet metal 9 to cover the flange of the side panel sheet metal 10 when the door sheet metal 9 is closed.

[0046] With the above settings, Figure 1 As shown, the mudguard portion 301, the mudguard lip 302, the main body 1 and the frame 2 are compositely extruded, the mudguard portion 301 faces the direction of the outside of the vehicle, and the mudguard portion 301 spans between the side panel sheet metal 10 and the door panel sheet metal 9, and is used to block the mud and sand splashed from the outside of the vehicle. The mudguard lip 302 is extended in the direction close to the side panel sheet metal 10 on the basis of the mudguard portion 301, thereby increasing the overall length of the bubble tube 3, so as to better block the mud and sand thrown from the outside of the vehicle.

[0047] At the same time, the mud guard lip 302 can be covered on the flange of the side panel sheet metal 10 after the door sheet metal 9 is closed. Compared with the situation in the prior art where the flange of the side panel sheet metal 10 is exposed and easy to accumulate mud, the setting of the mud guard lip 302 effectively avoids the accumulation of mud and sand on the flange of the side panel sheet metal 10.

[0048] The main body 1 and the bubble tube 3 are made of elastic material. The mudguard lip 302 in the bubble tube 3 made of elastic material has a certain elastic restoring force. The mudguard lip 302 is designed to overlap with the side panel sheet metal 10 when the door sheet metal 9 is closed. Then, after the door sheet metal 9 is closed, the mudguard lip 302 elastically contacts the side panel sheet metal 10 to generate deformation, and is tightly attached to and wrapped around the flange of the side panel sheet metal 10, thereby minimizing the gap to the greatest extent and achieving a better sealing effect.

[0049] The bubble tube 3 is in an arc shape, and the arc-shaped bubble tube 2 is protruding on the side of the door sheet metal 9 facing the outside of the vehicle. The arc-shaped bubble tube 3 can block the mud and sand splashing from the outside of the door sheet metal 9, and the mud splashing onto the bubble tube 3 will slide down along the shape of the arc edge, which has the effect of not easily accumulating mud and sand, and further enhances the effect of preventing mud and sand accumulation.

[0050] The arc-shaped bubble tube 3 is convex, wherein the arc-shaped edge bulges from both ends to the middle, so as to better enable the mud thrown onto the bubble tube 3 to slide down along the shape of the arc-shaped edge. At the same time, the arc-shaped edge with a convex shape enables the bubble tube 3 to have a better elastic recovery force, is not easy to be deformed under the impact of mud and sand, and can better maintain its original shape under the impact.

[0051] The bubble tube also includes a fitting portion 303; the fitting portion 303 is connected to the body 1 and the mudguard lip 302, and has a 3mm interference with the side panel metal to form an elastic contact. The fitting portion 303 is used to strengthen the sealing between the door panel metal 9 and the body 1, further enhancing the overall sealing. In the embodiment of the present invention, the fitting portion 303 is also in an arc shape and is opposite to the mudguard portion 301.

[0052] In the embodiment of the present invention, the fitting portion 303 and the mudguard portion 301 are extruded as a whole, which is simple to manufacture and has a relatively low cost.

[0053] The main body of the sealing strip includes a connecting portion 101, a seam-covering lip 5, an anti-slipping outer tooth 6, an anti-slipping inner tooth 8, and a positioning boss; the connecting portion 101 serves to connect the main body 1 and the mudguard 301, and has a clearance of 1 mm with the door exterior panel 11. The seam-covering lip 5 is connected to the main body 1 and fits with the door sheet metal 9, with an interference of 1 mm.

[0054] The anti-slip outer teeth 6 are connected to the body 1 and interfere with the PVC glue 7 of the door sheet metal 9 flange to prevent the wheel cover sealing strip from falling off. The anti-slip inner teeth 8 are connected to the body 1 and interfere with the door sheet metal 9 flange to prevent the wheel cover sealing strip from falling off.

[0055] The positioning boss 4 is connected to the body 1 and fits with the outer side of the door sheet metal 9 to position the wheel cover sealing strip in the Y direction; the structure is stable and reliable.

[0056] In the embodiment of the present invention, the connecting portion 101, the seam-covering lip 5, the anti-slipping outer teeth 6, the anti-slipping inner teeth 8, the positioning boss 4 and the body 1 are extruded as a whole, which is easy to manufacture and has a relatively low cost. In the embodiment of the present invention, the frame 2 and the body 1 are extruded as a whole, which effectively fixes the body 1 and the door sheet metal 9 firmly.

[0057] In the present invention, after the door sheet metal 9 is closed, more than half of the upper part of the fitting part 303 is closely attached to the side panel metal 10, and the fitting part 303 closely attached to the side panel metal 10 forms a planar contact surface, effectively blocking the inside from the outside, and having a better sealing effect on the edge of the side panel metal 10, greatly improving the sealing performance. The mud guard part 301 is not in contact with the door exterior panel 11, and the mud guard part 301 is connected to the connecting part 101 on the body 1, and has a certain distance from the door exterior panel 11, so as to leave a certain deformation space, which is stable and reliable.

[0058] The above is only an explanation of the preferred embodiments of the present invention, and the above technical features can be arbitrarily combined to form multiple embodiments of the present invention.

[0059] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
