[0002] An automotive roof rack, also known as a roof luggage rack, is a support or component installed on the top of a vehicle body, mainly used for safely and conveniently fixing luggage. This device is usually used on hatchback wagons, SUVs, MPVs and other vehicle models, aiming to solve the problem of insufficient interior space. Through the roof rack, items such as large-sized luggage, bicycles, folding beds, etc. can be carried. The roof rack not only plays a role in decoration and aesthetics, but more importantly, it can hold things that cannot be placed in the luggage compartment, thereby increasing the interior space and improving the load-carrying capacity of the vehicle.

[0003] Currently, most existing roof luggage racks are designed according to the corresponding automotive roof surface, which results in a limited range of vehicle models that the brackets on both sides of each automotive luggage rack are suitable for. When dealing with different roofs, brackets with different angular orientations need to be developed, which makes the brackets have poor versatility, and most of the brackets have poor connectivity with the crossbar. Summary of the Invention

[0052] Among them, the clamping assembly 4 includes a mounting bracket 41. One side surface of the mounting bracket 41 is mounted on the inner cavity side wall of the tripod bottom shell 22. On the other side of the mounting bracket 41 away from the tripod bottom shell 22, a rotating link bracket 43 is rotatably connected. The rotating link bracket 43 includes a nut pin 432. An upper connecting rod 433 is rotatably arranged on the upper part of the nut pin 432, and a lower connecting rod 431 is rotatably arranged on the lower part of the nut pin 432.

The activity limiting hole 421 can make the column at the top of the upper connecting rod 431 always move in a vertical straight line.

[0056] In this embodiment, when installing a roof rack on the vehicle roof, first, a pair of through-barless leg assemblies 2 are installed at the bottom of the through-bar assembly 1. First, the brake block 6 is installed on the locking link 8. At this time, the locking link 8 is located on the rotary connector 7, and the rotary connector 7 is located in the inner cavity of the leg bottom shell 22. When the brake block 6 needs to be installed, first move the locking link 8, and the spring 81 against the top post 74 can contract, so that the limiting chute 82 at the installation port 72 can move out, facilitating the limiting rod 62 to pass through the opening 223 and be stuck in the limiting chute 82. When the locking link 8 is released, the spring 81 releases its elastic potential energy and resets, so that the limiting rod 62 can be stuck in the limiting chute 82 and cannot break out, thus fixing the position of the brake block 6. The rotating rod 63 on one side is arranged in the rotating groove 73, so that the brake block 6 can be rotated and tilted at a certain angle, so that when installing the cross bar 12, more installation angles can be achieved.

[0057] After the brake block 6 is installed, the through-barless leg assembly 2 can be installed at the bottom of the cross bar 12. First, press the spring-loaded limit button 34 to contract it into the spring mounting seat 32, and then the sliding auxiliary plate 3 can move freely in the inner cavity of the cross bar 12, and the spring-loaded limit button 34 will not be restricted by the activity port 121. At this time, the brake block 6 can be inserted into the activity port 121 and enter the yarn port socket 31. Then, the limit card plate 61 and the sliding auxiliary plate 3 can slide together in the inner cavity of the cross bar 12. Then, the sliding auxiliary plate 3 is retracted again, and the spring-loaded limit button 34 is reset. In this way, when the sliding auxiliary plate 3 moves at the activity port 121, due to the restriction of the protruding spring-loaded limit button 34, the sliding auxiliary plate 3 will not slide to the position where the original brake block 6 can be separated, which can play an effective limiting role.

[0058] When installing the cross bar 12, the T-shaped screw can be slid into the slot at the top of the cross bar 12 by opening the limit cover plate 131, and the quick-installation strap 11 is directly pressed into the slot at the top of the cross bar 12.

[0059] After the brake block 6 is installed and fixed on the cross bar 12, the installation of the through-barless leg assembly 2 at the bottom of the cross bar 12 is completed. Then, select the first clamping seat 01, the second clamping seat 02, or the third clamping seat 03 that fits the vehicle roof. Although the structures of the three clamping seats 03 are different, they are all connected by inserting the hook 011 similar to that of the first clamping seat 01 into the clamping assembly 4.

[0060] First, the clamping assembly 4 is installed on the mounting block 224 through the mounting bracket 41 and cooperates with the fixing component for installation. Moreover, when the mounting bracket 41 is installed on the mounting block 224, it can rotate. And by setting the convex block 71 stuck in the limiting groove of the limiting convex block 411, the rotation angle of the mounting bracket 41 is a constantly changing value. In this way, the clamping assembly 4 drives the hook 011 to rotate a certain angle, so that the position of the cross bar 12 penetrating through the two sides of the non-longitudinal rod footrest assembly 2 is movable, thus increasing the overall versatility of the luggage rack and making it suitable for more cars with different car roofs.

[0061] When installing the hook 011, it is inserted through the hook socket 421, so that the mounting hook 011 can be located between the locking bracket 45 and the hook socket 421. And when the hook 011 passes through the hook socket 421, it will first press down the rotating locking bracket 45, so that it can press down the locking convex block 451. However, once the hook 011 passes through and the locking convex block 451 is located at the opening on the hook 011, at this time, with the cooperation of the locking convex block 451 and the torsion spring 44, and the upper connecting rod 433 and the lower connecting rod 431 cooperate with the hook pressing plate 42 to rotate, the locking convex block 451 can tilt up, while the hook pressing plate 42 presses down, thus clamping the inserted hook 011.

[0062] And the fixing component 9 fixes the rotating link frame 43, and the rotating link frame 43 makes the included angle between the hook pressing plate 42 smaller, so that it clamps more firmly. Moreover, the hook socket 421 is opened larger, and the locking convex block 451 is semi-circular, so that when the hook 011 is clamped on it, the hook 011 can swing a certain angle.

[0063] In the present invention, by arranging the cross bar 12 at the bottom of the non-longitudinal rod footrest assembly 2 passing through, the cross bar 12 can be lifted. And the arranged sliding auxiliary plate 3 can facilitate the quick connection between the brake block 6 and the cross bar 12 to achieve quick movement, so as to adapt to different car roof widths. Moreover, when the clamping assemblies 4 arranged on both sides are installed on the non-longitudinal rod footrest assembly 2 passing through, they can effectively clamp and connect different clamping seats and can be adapted to different vehicles. And the arranged clamping assemblies 4 can swing a certain angle, so that the installation angle is adjustable, thus realizing better versatility of the car luggage rack.

[0064] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
