Description

Technical Field

[0001] The utility model relates to an automobile accessory, in particular to a roof luggage rack for automobiles that can be installed without drilling holes. Background Art

[0002] With the rapid development of the automobile industry and the continuous improvement of consumers' living standards, automobiles are more and more widely used in daily life. In order to meet the needs of people to carry items during travel, handling large items or outdoor activities, roof luggage racks for automobiles, as an important automobile accessory, have been widely used. The existing roof luggage racks for automobiles are mainly installed in two ways: one is to fix the luggage rack on the roof of the car through bolts or rivets, which requires drilling holes in the roof of the car; the other is to clamp the luggage rack on the roof gutter through a clamping structure, which does not require drilling.

[0003] However, installing the luggage rack by drilling holes in the roof of the car will inevitably cause permanent damage to the body surface, affecting the beauty and structural integrity of the vehicle. Especially during use, the drilled holes are prone to bolt loosening due to uneven stress or long-term use, and even problems such as vehicle body leakage and rusting may occur, reducing the service life and safety of the vehicle.

[0004] In addition, the drilling installation process is relatively complex, requires professional operation, and the installation position needs to be accurately measured and positioned, with a long construction time and high cost, which is not conducive to users' self-installation and disassembly. The curvature, thickness and structure of the roofs of the same model of cars are different, resulting in the same luggage rack may not be applicable to all models, reducing the versatility and market applicability of the luggage rack.

[0005] In addition, the currently commonly used roof luggage racks for non-destructive installation usually fix the luggage rack on the roof gutter through clamps or rubber pads. This method relies on the clamping force of the clamping components, and the fixing strength is not high enough. When driving at high speed or carrying a large load, there is a risk of the luggage rack loosening or even falling off, posing a greater safety hazard.

[0006] The existing non-destructive installation luggage racks are usually not flexible enough in the structural design of the clamping part, and the adaptability of the clamping plate to the roof gutter is poor, and the height and position cannot be accurately adjusted, resulting in problems such as easy tilting or insecure fixing of the luggage rack during installation. Although the non-destructive installation luggage rack does not require drilling holes in the roof, if the part where the clamp directly contacts the vehicle body surface is not properly handled during installation, it is easy to scratch the car paint or the vehicle body surface during the clamping process, affecting the appearance of the vehicle. Therefore, it is necessary to make further improvements to it. Summary of the Utility Model
