Technical Field

[0001] The utility model relates to the field of automobile door structures, in particular to a sealing strip, a door sealing strip structure and an automobile thereof. Background Art

[0002] At present, the production of vehicle door assemblies is inseparable from the edge wrapping structure between the vehicle door outer panel and the vehicle door inner panel, wherein the edge wrapping structure is coated with edge wrapping glue for sheet metal anti-corrosion sealing, but the edge wrapping glue is often coated unevenly, and the existing sealing strips for vehicle doors, such as a sealing strip structure disclosed in the patent document with publication number "CN214928897U", include a sealing structure and a retaining edge structure, wherein, for the connection between the vehicle door outer panel and the vehicle door inner panel, that is, the edge wrapping structure, it is only overlapped by the retaining edge structure, and the edge wrapping glue on the edge wrapping structure is not blocked, resulting in an unsightly shape and affecting the overall texture of the vehicle door. Utility Model Content

[0003] One of the purposes of the utility model is to provide a sealing strip to solve the problem that the edge glue in the prior art affects the overall texture of the door; the second purpose is to provide a door sealing strip structure; the third purpose is to provide a car.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A sealing strip comprises a base, a first lip edge and a second lip edge arranged on the base, wherein the first lip edge is used to overlap with the edge of a vehicle door outer panel, and the second lip edge is used to overlap with the vehicle door inner panel; a gap is provided on the first lip edge, and the gap is used to accommodate the edge glue on the edge structure.

[0006] According to the above technical means, when the sealing strip is installed, the base is generally installed on the inner door panel, the first lip edge overlaps the edge of the door outer panel, and the second lip edge overlaps the door inner panel, so as to form a sealing structure on the door. Among them, the edge structure formed between the door outer panel and the door inner panel is coated with edge glue, and the airtight portion on the sealing strip matches the edge glue. After the sealing strip is installed, the edge glue is located in the airtight portion, and the first lip edge can wrap and cover the edge glue.

[0007] Furthermore, a reinforcing rib is provided on one end of the base body close to the first lip; the reinforcing rib is located on one side of the air avoidance portion.

[0008] According to the above technical means, the thickness of the first lip itself is thinner than the base. After the air avoidance portion is provided, the thickness of the first lip is even thinner, and its strength is insufficient, which may cause the flash to separate during the assembly of the actual vehicle. By providing the reinforcing ribs, the first lip is provided with strength support, thereby avoiding the problem of the first lip separating from the flash during the assembly of the actual vehicle.

[0009] Furthermore, the thickness of the reinforcing rib is greater than the thickness of the first lip.

[0010] According to the above technical means, the thickness of the reinforcing rib is greater than the thickness of the first lip, and the strength support for the first lip is better.

[0011] Furthermore, the base is provided with a receiving cavity for installing a clip.

[0012] According to the above technical means, the accommodating cavity can accommodate the head of the clip, so that the clip can be assembled in a hidden manner. After the sealing strip is assembled, the clip is not visible from the appearance, which is more concise.

[0013] Furthermore, the accommodating cavities are distributed along the length direction of the substrate, and the distance between two adjacent accommodating cavities is less than or equal to 100 mm.

[0014] The utility model also provides a vehicle door sealing strip structure, comprising a vehicle door outer panel, a vehicle door inner panel connected to the vehicle door outer panel, a vehicle door sheet metal part welded to the vehicle door inner panel and the above-mentioned sealing strip, wherein the connection between the vehicle door outer panel and the vehicle door inner panel has an edging structure, and the edging structure is coated with edging glue; the base is connected to the vehicle door inner panel, the first lip edge overlaps the edging of the vehicle door outer panel, the second lip edge overlaps the vehicle door inner panel, the edging glue is located in the air avoidance portion, and the first lip edge wraps the edging glue.

[0015] According to the above technical means, a edging structure is provided at the stop edge of the door outer panel and the door inner panel, the door outer panel wraps the edge of the door inner panel, and the door sheet metal is provided between the door inner panel and the door outer panel and welded to the door inner panel to increase the strength of the door inner panel. The sealing strip is installed on the door inner panel through its base, and the first lip edge and the second lip edge overlap the door outer panel and the door inner panel respectively, wherein the first lip edge overlaps and interferes with the edging of the door outer panel, and the second lip edge overlaps and interferes with the door inner panel. The overlap and interference of the first lip edge and the second lip edge can avoid the risk of overlapping and separating the sealing strip caused by the manufacturing tolerance of the actual vehicle.

[0016] Furthermore, the vehicle door inner panel is provided with a rounded corner portion, and the second lip edge is overlapped to the rounded corner portion of the vehicle door inner panel.

[0017] According to the above technical means, the inner door panel will be provided with a rounded corner. When the second lip edge overlaps there, the sealing strip will have a smooth transition to the inner door panel after being assembled in the actual vehicle.

[0018] Furthermore, the width of the base is greater than the welding area between the door inner panel and the door sheet metal component.

[0019] According to the above-mentioned technical means, the welding area between the door inner panel and the door sheet metal will form an appearance weld spot gravure, forming an appearance defect, and the width of the substrate is larger than the welding area. During installation, the substrate can cover the welding area and mask the weld spot gravure.

[0020] Furthermore, a clip is installed on the base, and the base is clamped with the door inner panel through the clip.

[0021] The utility model also provides a car, comprising a car body and a car door installed on the car body, wherein the car door has the above-mentioned car door sealing strip structure.

[0022] The beneficial effects of the utility model are as follows: 1. The sealing strip accommodates the edge glue through the avoidance portion, so that the first lip edge wraps the edge glue to shield the edge glue, thereby improving the appearance and texture of the car door; at the same time, through the effect of the reinforcing ribs, the first lip edge still has sufficient strength after forming the avoidance portion, and the problem of flashing and seam separation will not occur after the sealing strip is assembled. 2. The width of the base can shield the welding point gravure, further improving the appearance and texture of the car door. BRIEF DESCRIPTION OF THE DRAWINGS
