Description
Technical Field
[0001] The utility model belongs to the technical field of automotive sky doors, and more specifically, it relates to a sealing structure for the gap of an automotive sky door. Background Art
[0002] With the upgrading of automobiles, the requirements for functions are getting higher and higher, and the specific use environments of automobiles are gradually increasing. The sky door structure appears. Different from the traditional rear door, the sky door is divided into a sky door and a ground door. The sky door opens upward, and the ground door opens downward, which can make the whole rear part open wider, facilitating the loading and unloading of goods. At the same time, people can sit on it after the ground door is opened, meeting the needs of customers in outdoor camping, fishing and other scenarios; because the rear door is divided into a sky door and a ground door, the sealing performance between the up and down openings becomes higher. In conventional sky door models, there is only one seal in the middle, and the waterproof performance is not good, and the gap between the doors is directly exposed, making it easy for dust to enter.
[0003] There is a technology named "A Sealing Structure for the Gap of a Car Door" with a publication number of "CN206394405U" in the prior art. This technology relates to the field of automobiles and particularly relates to a sealing structure for the gap of a car door. The sealing structure for the gap of a car door includes: a plastic strip, a rubber sealing strip and a T-shaped fixing part; the rubber sealing strip includes: a first shielding part, a second shielding part and a fixing part. The first shielding part and the second shielding part are respectively arranged at both ends of the fixing part. The first shielding part is used to shield the gap between the doors, and the second shielding part is used to seal the edge of the outer panel of the rear door. A long round hole is arranged on the inner side of the fixing part; the T-shaped fixing part is welded on the outer panel of the rear door, and the fixing part is connected to the T-shaped fixing part through the long round hole; the plastic strip is clamped between the rubber sealing strip and the T-shaped fixing part, and a through groove is respectively arranged on both sides of the top of the plastic strip and the T-shaped fixing part. When the plastic strip is clamped into the T-shaped fixing part, the through grooves on both sides of the plastic strip can generate large deformation so that the plastic strip can be more easily clamped into the T-shaped fixing part, and the plastic strip is not easily squeezed and broken by the T-shaped fixing part. However, this technology does not involve the technical problems and technical solutions of this application. Summary of the Utility Model
