Abstract
Description
Technical Field
[0001] The utility model relates to the field of automobile accessories, in particular to a door noise-proofing strip corner fixing device and a door and a car comprising the same. Background Art
[0002] The door noise reduction strip corner fixing device is one of the door structures, which plays the role of fixing the door noise reduction strip. At present, noise reduction sealing strips are set at the upper frame position of the door of mainstream models, which helps to improve the NVH performance of the whole vehicle and the driving comfort of passengers. The upper noise reduction strip is generally integrated on the door sealing strip or the door glass guide groove. When the upper sealing strip is integrated in the door glass guide groove, the noise reduction strip is connected to the door sheet metal by a clip-on method. Affected by the sheet metal shape, process and installation environment, the C-pillar noise reduction strip corner part is prone to loose connection and looseness under force. The current solution is to build a buckle into the C-pillar corner part, open a hole in the sheet metal, and clip it on the sheet metal. This method can effectively improve the strength of the corner. However, when the door noise reduction strip corner fixing device is used, the clip point is affected by the sheet metal shape and process, and can only be as close to the C-pillar corner as possible, and there is still a certain distance from the end of the corner. The force will still produce a certain amount of shaking, affecting the driving experience. Utility Model Content
