[0035] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0036] Embodiment 1

[0037] This embodiment relates to a car door gap sealing structure, which provides a structural solution for sealing the gap between the door and the fender 5; an exemplary structure thereof is as follows Figure 1 and Figure 2 shown.

[0038] In general, the automobile door gap sealing structure includes a door sheet metal 1 and a door gap sealing assembly arranged on the door sheet metal 1. The door sheet metal 1 includes a door inner panel 10 and a door outer panel 11 overlapped and connected at the edge; the door gap sealing assembly includes a frame 2 overlapped on the door inner panel 10, and a sealing strip 3 integrated at the end of the frame 2. The end of the frame 2 extends to the gap between the door sheet metal 1 and the fender 5. When the door is closed, the sealing strip 3 forms a seal for the gap between the door sheet metal 1 and the fender 5.

[0039] It should be pointed out that, based on the above-mentioned overall design concept, the technical solution of the utility model can adopt a variety of different specific implementation structures, forms or configuration sequences. For example, the specific structural form of the above-mentioned skeleton 2 can have a variety of schemes. For the parts required for the implementation of the overall scheme but not involved in the above-mentioned overall setting, reasonable and flexible designs can be made with reference to the mature setting means in the field, the actual situation during implementation, etc. The specific implementation scheme described below in this embodiment is only one of the many schemes that can be formed by the above-mentioned various combinations and their variations. In actual implementation, those skilled in the art can make flexible adjustments and improvements based on the actual situation. Obviously, the many schemes that can be formed by the combination of the above-mentioned various specific forms and their variations, as well as the specific implementation scheme of this embodiment, are all within the protection scope of the utility model.

[0040] Specifically, in this embodiment, the frame 2 includes an overlapping portion 20 and an extension portion 22 which are integrally connected, wherein the overlapping portion 20 overlaps the inner side of the door inner panel 10, the extension portion 22 is bent relative to the overlapping portion 20 and extends toward the gap, and the sealing strip 3 is arranged at the end of the extension portion 22.

[0041] The frame 2 is configured to be composed of two relatively bent overlapping portions 20 and an extended portion 22, and the overlapping portion 20 overlaps the inner side of the door inner panel 10, which can provide a flat and stable installation foundation for the overlapping of the frame 2 on the door inner panel 10. The bent extended portion 22 can be well extended to the gap between the fender 5 and the door sheet metal 1, providing good conditions for the sealing strip 3 at the end of the extended portion 22 to be sealed and attached at the gap. The material of the frame 2 can of course be flexibly selected; in the present embodiment, the frame 2 is made of PP+EPDM-TD20 material, and the overlapping portion 20 extends to the inner surface edge of the door inner panel 10 to form an overlapping structure with the door inner panel 10; after the overlapping portion 20 protrudes out of the inner surface of the door inner panel 10, it is bent toward the gap direction to form an extension portion 22, so that the cross-sectional shape of the frame 2 is roughly "L"-shaped, which can avoid large-area fitting between the door inner panel 10 and the frame 2, improve matching accuracy, avoid material waste, and form a cavity structure between the frame 2 and the door inner panel 10, which is beneficial to improving the overall buffering performance and sound insulation effect of the vehicle door.

[0042] like Figure 3 Figure 4 and Figure 5 As shown, the overlap portion 20 of this embodiment includes a main overlap portion 200 extending along the length direction of the gap, and a top overlap portion 201 bent and formed at the top of the main overlap portion 200. The main overlap portion 200 overlaps the inner side of the door inner panel 10, and the top overlap portion 201 is arranged perpendicular to the front-rear direction of the vehicle and overlaps the glass corner 6.

[0043] By utilizing the overlapping connection between the main overlap portion 200 and the door inner panel 10, the frame 2 can be restricted and fixed in the direction of the vehicle door thickness (the left and right direction of the vehicle). When multiple main mounting holes are provided on the main overlap portion 200, the clamping operation is also facilitated. The provision of the top overlap portion 201 at the top of the main overlap portion 200 can form a reliable fixed connection between the top overlap portion 201 and the glass felt corner 6, thereby forming a fixed restriction on the frame 2 in the direction of the vehicle door width (the front and rear direction of the vehicle). The above main overlap portion 200 and the top overlap portion 201 restrict and fix the frame 2 in multiple directions, improve the structural installation stability of the frame 2, and can also prevent the top of the frame 2 from warping. At this time, the top of the frame 2 and the glass felt corner 6 are crimped and matched, which not only forms a fixation for the door seam sealing assembly, but also effectively solves the problem of the glass felt corner 6 being easily warped.

[0044] There are many forms of overlapping and fixing. For example, the overlapping parts can be fixed together by screwing, welding, etc. However, in this embodiment, a plurality of mounting holes 21 are provided on the overlapping portion 20, and the frame 2 is connected to the vehicle door by a plurality of clips 4 respectively inserted into the mounting holes 21. The frame 2 and the door inner panel 10 are connected by clips 4, which can be conveniently installed with the help of standardized clips. Each clip 4 is inserted into the mounting hole 21 on the overlapping portion 20, and then inserted into the first clip hole 100 provided on the door inner panel 10, or the second clip hole 600 provided on the glass corner 6, so that the frame 2 can be firmly fixed to the vehicle door.

[0045] Specifically, the mounting holes 21 of this embodiment include a plurality of main mounting holes spaced apart on the main overlap portion 200, and a top mounting hole 211 disposed on the top overlap portion 201; the main overlap portion 200 is clamped to the door inner panel 10 by a plurality of clips 4 respectively passed through the main mounting holes, and the top overlap portion 201 is clamped to the glass frame corner 6 by a clip 4 passed through the top mounting hole 211.

[0046] Combination Figure 4 , Figure 5As shown, the skeleton 2 of this embodiment is installed by seven clips 4; wherein, the spacing between the main mounting holes on the main overlap portion 200 is designed to be between 100mm and 150mm in the first clip hole; the six middle mounting holes 210 located in the middle of the main overlap portion 200 are closer to the sealing strip 3 and can be controlled at 50mm to 60mm; the top mounting hole 211 at the top and the bottom mounting hole 212 at the bottom are controlled within 80mm from the sealing strip 3, which can effectively ensure the overall structural stability of the skeleton 2 and the reliability of the fixing of the sealing strip 3.

[0047] Furthermore, the main mounting holes include a bottom mounting hole 212 located at the bottom of the main overlap portion 200, and a plurality of middle mounting holes 210 spaced apart in the middle of the main overlap portion 200. Preferably, the top mounting hole 211 and the bottom mounting hole 212 are circular hole structures, and the remaining middle mounting holes 210 are designed as oblong holes, which can absorb the manufacturing tolerance of the parts and avoid the problem that the buckle 4 cannot be engaged.

[0048] Based on the overall structural shape of the frame 2, a boss 23 is formed on the plate of the overlap portion 20 in this embodiment, where each mounting hole 21 is located; and each boss 23 is convexly arranged opposite to the snap-in direction of the buckle 4, and each mounting hole 21 is respectively opened on each boss 23. In addition, weight-reducing holes, avoidance notches, strengthening protrusions and other structures can also be arranged on the overlap portion 20. Figure 4 As shown in FIG. 1 , a reinforcing protrusion 202 is provided between the two mounting holes 21 in the middle.

[0049] The structure of the boss 23 is designed in the position where the mounting hole 21 is located in cooperation with the door inner panel 10, which can effectively improve the clamping strength. In this embodiment, the boss 23 is 0.5 mm higher than the peripheral area, so that a gap is formed between the boss 23 and the door inner panel 10. When the buckle 4 is clamped, the mounting hole 21 can be deformed in the plate thickness direction of the door inner panel 10 to approach the door inner panel 10, which can ensure that most of the plate area of ​​the overlap portion 20 fits the door inner panel 10 well, and facilitate the clamping of the buckle 4 to the bottom. With the design of the above-mentioned boss 23, the mounting surface of the buckle 4 is partially fitted with the door inner panel 10, avoiding the large-area fitting of the overlap portion 20 of the frame 2 with the door inner panel 10, which can effectively avoid the interference between the hard plastic of the frame 2 and the door inner panel 10, and the loosening and abnormal noise that may be caused.

[0050] At the same time, the area outside the mounting hole 21 on the overlap portion 20 can be flexibly provided with structures such as reinforcing protrusions 202 and weight-reducing strip holes, and avoidance gaps can also be designed for the protruding structures on the door inner panel 10. The weight-reducing holes are convenient for reducing the weight of the frame 2, and the avoidance gaps can avoid the protruding structures on the door inner panel 10, so that the frame 2 can be better overlapped on the door inner panel 10; the design of the reinforcing protrusions 202 is conducive to improving the structural strength of the overlap portion 20, preventing product deformation, and improving assembly accuracy.

[0051] like Figure 5 As shown, the end of the extension portion 22 of this embodiment is provided with a step structure 220, and the sealing strip 3 is fixedly connected to the step structure 220. The L-shaped step structure at the end of the extension portion 22 can effectively increase the connection area between the sealing strip 3 and the extension portion 22, thereby improving the connection firmness between the frame 2 and the sealing strip 3.

[0052] In addition, the sealing strip 3 of this embodiment includes a connecting portion 30 connected to the end of the frame 2, and a sealing portion 31 formed on the connecting portion 30. The sealing portion 31 is arched from one side of the inner part of the gap toward the gap. The sealing strip 3 of this embodiment preferably uses TPV material. With respect to the end connected to the end of the extension portion 22, the other end of the sealing strip 3 adopts a lip structure to overlap with the flange of the fender 5. The middle part of the sealing strip 3 serves as the sealing portion 31, which is connected to the edging structure on both sides through the arc-shaped arched structure, which not only ensures the sealing effect, but also improves the appearance matching. During the specific design, an interference amount of 1.0mm to 1.5mm is designed between the lip structure at the end of the sealing part 31 and the fender 5, and an interference amount of 0.5mm is designed between the arched structure of the sealing part 31 and the edging 110 of the door sheet metal 1. This can effectively shield the gap between the door sheet metal 1 and the fender 5, prevent external dust from entering the vehicle, improve the aesthetics of the entire vehicle, and at the same time greatly improve the air tightness of the entire vehicle.

[0053] In summary, the automobile door gap sealing structure of the present embodiment is provided with a door gap sealing assembly on the door inner panel 10, and a sealing strip 3 for sealing is integrated at the end of the door gap sealing assembly, and the frame 2 of the door gap sealing assembly is overlapped and fixed on the door inner panel 10. By utilizing the supporting property of the frame 2, the sealing strip 3 can be accurately set corresponding to the gap between the door sheet metal 1 and the fender 5, so that the sealing strip 3 is sealed and filled in the gap, so as to have a good sealing effect on the gap between the fender 5 and the door, thereby providing a structural solution for sealing the gap between the door and the fender 5.

[0054] Embodiment 2

[0056] The automobile door gap sealing structure of the utility model is adopted, and the sealing strip 3 arranged on the frame 2 can form a reliable sealing effect at the gap between the door sheet metal 1 and the fender 5; the problem that the gap between the door panel and the fender 5 of the traditional door is large and the air tightness of the whole vehicle is poor is solved, and at the same time, the dust accumulation at the gap between the door sheet metal 1 and the fender 5 is effectively improved, and the aesthetics of the door at this position is greatly improved. In the automobile door gap sealing structure of the utility model, each mounting hole 21 on the frame 2 is arranged on the boss 23, and the frame 2 can be conveniently and firmly fixed on the door inner panel 10 by using the buckle 4. The sealing strip 3 integrated on the extension part 22 is provided with an arc-shaped arched lip structure, which can form a good sealing blockage for the gap between the door sheet metal 1 and the fender 5, effectively solve the problem of external dust entering the vehicle through the gap, improve the aesthetics of the whole vehicle, and avoid the problem of local driving wind noise of the vehicle body, and improve the air tightness performance of the whole vehicle.
