Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of automobile side skirts, and particularly to an assembled automobile side skirt and an assembling method thereof. Background Art
[0002] The automobile side skirt on an electric vehicle refers to the skirt plates installed on both sides of the vehicle body door panel, which can be used to reduce the airflow on both sides of the vehicle body from entering the bottom of the vehicle. In addition, the side skirt has a certain flow disturbance effect, that is, when the vehicle is running at a high speed, the air resistance generated by the side skirt makes the airflow smoothly pass under the vehicle, and will not cause the vehicle to drift during driving, thus greatly increasing the operation stability.
[0003] For example, the publication number is CN103264727A, and on August 28, 2013, a side skirt assembly was disclosed. The side skirt assembly includes a side skirt body, a buckle, and double-sided tape. Each end of the side skirt body is provided with an installation hole, and the installation hole is connected to the inner sheet metal by screws. The buckle is connected to the side skirt body through a buckle positioning hole. The double-sided tape is pasted on the upper surface of the side skirt body. The buckle positioning hole includes a main reference positioning hole and six secondary reference positioning holes. The main reference positioning hole is arranged in the middle of the side skirt body, and the secondary reference positioning holes are evenly distributed on both sides of the side skirt body. The axial runout of the main reference positioning hole is 0.05 - 0.15 mm, and the normal offset is 0.05 - 0.15 mm. The axial runout of the secondary reference positioning hole is 1.0 - 2.0 mm, and the normal offset is 0.05 - 0.15 mm. When forming the structure of the long side skirt of a large electric vehicle with the above-disclosed side skirt structure, the positioning structure of the side skirt is not easy to demold due to the mold display, resulting in high manufacturing cost and poor practicability of the long side skirt.
