Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle-mounted luggage frames, and specifically relates to an automobile luggage rack. Background Art

[0002] With the rapid development of China's economy and the continuous improvement of residents' living standards, the automobile market has entered a prosperous era in the past decade. As a mass consumer product, automobiles have entered thousands of households. With the continuous improvement of people's requirements for the quality of life and driving comfort, the sizes of passenger cars on the market are constantly increasing in length and width, and the interior space also increases accordingly. However, when people need to load a lot of luggage items during long-distance travel, or need to load some specific large-sized luggage items, such as outdoor tents, bicycles, water sports equipment, suitcases, etc., the interior space will be significantly insufficient and cannot meet the storage requirements.

[0003] In view of this, due to its ability to increase the loading capacity of the vehicle and extend the interior space, automobile luggage racks are accepted and used by more and more users. Generally speaking, the existing automobile luggage racks are usually composed of sheet metal parts connected by bolts, and then the automobile luggage racks are fixedly installed on the roof of the vehicle. In order to reduce the weight of the automobile luggage rack itself, the installation requirements between sheet metal parts, and ensure the stiffness requirements of the automobile luggage rack, installation grooves or process structure grooves are often set on the sheet metal parts to achieve this. However, when the vehicle is running, the airflow will form wind resistance or eddy currents on the wind resistance surface of the structural parts of the automobile luggage rack, installation grooves, and process structure grooves, resulting in wind noise generated by the automobile luggage rack under the action of the wind.

[0004] In view of this, the present utility model is specifically proposed. Content of the Utility Model

The heating wires are connected to the vehicle battery. When encountering rainy or snowy weather, the heating wires can be turned on for heating to melt the snow on the vehicle roof rack.

[0092] The above are only the preferred embodiments of the present utility model and do not impose any formal restrictions on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present utility model, may make some changes or modifications using the technical content prompted above to form equivalent embodiments of equivalent changes.
