[0026] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] Reference Figures 1-7A roof rack crossbar includes a connecting rod 1, two connecting pieces 7, and two connecting mechanisms. The two connecting mechanisms are respectively used to install on both sides of the roof. The connecting rod 1 is used to connect the two connecting mechanisms on both sides. The connecting pieces 7 are used to position the connecting mechanisms on the roof. Thus, the shape of the connecting pieces 7 allows them to be installed on the top of the vehicle door from bottom to top, and the connection between the connecting pieces 7 and the fixed base 3 prevents them from falling down.

[0030] In this embodiment, buffer pads are provided at all locations where the connector 7 contacts the vehicle body to prevent the connector 7 from scratching the vehicle paint.

[0031] In this embodiment, a crossbar includes at least one connecting rod 1, two connecting pieces 7, and two connecting mechanisms.

[0032] The connecting mechanism includes a fixed base 3, a connecting frame 4, and an adjusting plate 5. The connecting frame 4 is installed on the top of the fixed base 3. An anti-slip sleeve is fixed on the outer side of the bottom end of the fixed base 3 to prevent the fixed base 3 from moving on the roof of the vehicle and to prevent the fixed base 3 from directly contacting the roof of the vehicle and causing scratches to the paint. The connecting frame 4 is provided with an adjusting plate 5 on the top, and the connecting rod 1 is supported in position by the two adjusting plates 5.

[0033] In this embodiment, both the fixed base 3 and the connector 7 are made of 304 stainless steel with a vertical design to achieve maximum load-bearing capacity, and the welding treatment at the bends makes them less prone to breakage.

[0034] Mounting plates 15 are fixed at both ends of the top of the fixed base 3, and both mounting plates 15 are located inside the connecting frame 4. The mounting plates 15 are slidably connected to the connecting frame 4, so that the connecting frame 4 can be directly located outside the two mounting plates 15 on the top of the fixed base 3 by sliding. The connecting frame 4 and the mounting plates 15 are connected by the third fastening bolt 14, so that the connecting frame 4 and the mounting plates 15 can be positioned by the third fastening bolt 14. A positioning plate 16 is fixed on one side of the top of the fixed base 3.

[0035] A clamping plate 13 is fixed to one side of the top of the connecting frame 4. The clamping plate 13 is L-shaped, so that a cavity is formed between the top of the connecting frame 4 and the clamping plate 13. The clamping plate 13 is slidably connected to the adjusting plate 5, so that the adjusting plate 5 can directly enter the position between the top of the connecting frame 4 and the clamping plate 13 through the sliding detachable connection. The clamping plate 13 and the adjusting plate 5 are connected by the second fastening bolt 12. So that after the adjusting plate 5 slides into the space between the clamping plate 13 and the connecting frame 4, the second fastening bolt 12 descends from the top of the clamping plate 13 and enters the interior of the adjusting plate 5, so that the connection between the adjusting plate 5 and the clamping plate 13 is stable and cannot be separated.

[0036] In this embodiment, a protective cover 6 is slidably fitted on the outer side of the connecting frame 4. In other embodiments, a lock can be installed on the inner side of the protective cover 6, allowing the lock tongue to enter the through groove inside the connecting frame 4, thereby achieving a stable connection between the protective cover 6 and the connecting frame 4.

[0037] The connecting rod 1 is elliptical in shape. A first mounting groove 8 is formed at the bottom of both sides of the connecting rod 1. The connecting rod 1 and the adjusting plate 5 are slidably connected through the first mounting groove 8, allowing the adjusting plate 5 to slide into the inner position of the first mounting groove 8 in the connecting rod 1. A second mounting groove 9 is formed at the top of both sides of the connecting rod 1. The connecting rod 1 and the adjusting plate 5 are connected by a first fastening bolt 11. When the adjusting plate 5 is located inside the first mounting groove 8, the first fastening bolt 11 descends from the top of the second mounting groove 9, fixing the connecting rod 1 and the adjusting plate 5 in place. A sealing strip 2 is provided at the top of the connecting rod 1. Elastic blocks 10 are fixed to both ends of the bottom of the sealing strip 2. The elastic blocks 10 are detachably connected to the connecting rod 1 through the second mounting groove 9. The elastic blocks 10 are L-shaped.

[0038] This allows the elastic block 10 on the sealing strip 2 to deform and enter the top of the inner side of the second assembly groove 9, thereby closing the top of the second assembly groove 9 on the connecting rod 1 through the sealing strip 2.

[0039] In this embodiment, both the sealing strip 2 and the elastic block 10 are made of elastic material, such as rubber.

[0040] The connector 7 includes a first connecting piece 18, a second connecting piece 19, and a third connecting piece 20. The third connecting piece 20 is fixed to one side of the top of the first connecting piece 18. The third connecting piece 20 is connected to the positioning plate 16 by a fourth fastening bolt 17, which allows the connector 7 and the positioning plate 16 to be separated or fixed by the fourth fastening bolt 17. The second connecting piece 19 is fixed to the bottom of the first connecting piece 18. Thus, the bottom of the connector 7 is positioned relative to the top of the door in the vehicle body by the arc shape of the first connecting piece 18 and the bending of the second connecting piece 19.

[0041] In this embodiment, the second connecting piece 19 on the connector 7 adopts a small-angle hook, which has a large pulling force and a thin hook piece that does not affect the electric sliding door. At the same time, it ensures that the original vehicle rubber strip is not damaged during the installation of the connector 7, and it is installed under the rubber strip.

[0042] In this embodiment, the connector 7 is a replaceable structure, which is designed for specific vehicles and can be replaced during assembly according to the shape of various vehicles.

[0043] In this embodiment, the overall height of the crossbar structure is 8 cm. After installation on many vehicle models, the actual height increases by about 5 cm, which reduces the overall height, improves passability, reduces wind resistance, and meets the vehicle management office's filing requirements.

[0044] In this embodiment, each structure has its own service life. In actual manufacturing and application, the corresponding structure made of different materials can be replaced according to the needs of use.

[0045] The usage process of the roof rack crossbar provided by this utility model is as follows: First, the connecting piece 7 is supported by a pre-attached structure such as a silicone pad and installed at the top of the car door. It is positioned using the hook shape of the second connecting piece 19. Then, the fixing base 3, supported by an external anti-slip pad or silicone pad, is placed on the roof, corresponding to the position of the connecting piece 7. After assembling the connecting piece 7, the third connecting piece 20 and the positioning plate 16 are fixed using the fourth fastening bolt 17. At this point, the connecting piece 7 and the fixing base 3 are structurally positioned. Then, the connecting bracket 4 is slidably installed on the outside of the two mounting plates 15 on top of the fixing base 3. The connecting frame 4 and the assembly plate 15 are fixed with the third fastening bolt 14. Then, the adjusting plate 5 is slidably installed inside the first assembly groove 8 on the connecting rod 1. At this time, the connecting rod 1 is located between the two connecting frames 4. The adjusting plate 5 is slidably inserted from the inside of the connecting rod 1 into the position between the top of the connecting frame 4 and the clamping plate 13. The adjusting plate 5 and the clamping plate 13 are fixed with the second fastening bolt 12. Then, the adjusting plate 5 and the connecting rod 1 are fixed with the first fastening bolt 11. Then, the sealing strip 2 is installed at the top position of the second assembly groove 9 on the connecting rod 1 by the deformation of the elastic block 10. Finally, the protective cover 6 is installed on the outside of the connecting frame 4 to protect the different bolts on the connecting frame 4.
