[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 The present invention provides a technical solution: an adjustable multi-functional extended car roof rack, including a fixed base assembly 1, an adjustable crossbar assembly 2 and a multi-functional extension assembly 3; the fixed base assembly 1 is symmetrically arranged on both sides of the car roof and is installed on the longitudinal rail 4 of the car roof, the adjustable crossbar assembly 2 is horizontally mounted between the two fixed base assemblies 1, and the multi-functional extension assembly 3 is connected to the adjustable crossbar assembly 2.

[0023] The fixed base assembly 1 includes a base body 11, a clamping member 12, and a buffer pad 13. The clamping member 12 is integrally provided on the lower side of the base body 11. The bottom of the clamping member 12 has a slot adapted to the longitudinal rail 4 of the car roof. A sliding groove is formed on the inner wall of the slot, and a clamping block 15 is provided within the sliding groove. A first bolt 14 is rotatably connected to the clamping block 15, passing through the side of the clamping member 12 and threadedly connected to it. The buffer pad 13 is attached to the inner wall of the slot. The lateral clamping of the clamping member 12 and the first bolt 14 solves the core problem of "loose installation." At the same time, the movable position of the clamping block 15 effectively increases the device's versatility, eliminating the need to design dedicated bases for different car models and reducing the cost of repeated purchases after users change car models. Through the "slot engagement + bolt tightening" installation method, installation can be quickly completed with only an adjustable wrench, without the need for professional tools. Compared to traditional luggage racks that require drilling for fixing, installation efficiency is greatly improved, and disassembly is convenient, meeting users' needs for "installation on demand." The buffer pad 13 can buffer driving vibrations and reduce the damage of vibrations to the roof paint and roof rack components; at the same time, the buffer pad 13 fills the gap between the clamping piece 12 and the longitudinal rail 4 of the car roof, avoiding direct metal friction that generates noise and improving the driving experience.

[0024] The adjustable crossbar assembly 2 includes a crossbar body 21, a sliding block 22, and a second bolt 23. The sliding block 22 is sleeved on the outside of the base body 11 and can slide smoothly along the length of the base body 11. The sliding block 22 is fixedly connected to both ends of the crossbar body 21, and the crossbar spacing can be flexibly adjusted according to the size of the item, solving the problem of "poor adaptability" of traditional fixed spacing crossbars. The second bolt 23 is threaded into the threaded hole on the side wall of the sliding block 22, and its end abuts against the side wall of the base body 11. A silicone anti-slip pad can be sleeved on the second bolt 23 to effectively prevent the sliding block 22 from loosening and improve the locking reliability.

[0025] The multi-functional expansion component 3 includes a folding expansion platform 31, a rotating joint 32, a pivot 33, a first pin hole 34, a connecting hinge 35, a second pin hole 36, and a third pin hole 37. The rotating joint 32 is fixed to the side of the folding expansion platform 31. The rotating joint 32 is connected to the outside of the crossbar body 21 via the connecting hinge 35. The connecting hinge 35 has second pin holes 36 and third pin holes 37. The rotating joint 32 has a first pin hole 34 aligned with it. A positioning pin passes through the first pin hole 34, second pin hole 36, and third pin hole 37, ensuring the rotating joint 32 maintains a stable horizontal and vertical position on the connecting hinge 35. The folding expansion platform 31 achieves "folding-unfolding" switching through the connecting hinge 35 and the positioning pin. When unfolded, it increases the loading volume, facilitating the stable placement of large items on the roof of the vehicle. When folded, it is parallel to the crossbar, reducing wind resistance and resolving the contradiction of "large items being unstable while small items taking up space."

[0026] A reinforcing rib 24 is integrally provided between the crossbar body 21 and the sliding block 22. The reinforcing rib 24 has a triangular structure. Utilizing the principle of "triangle stability", the connection strength between the crossbar body 21 and the sliding block 22 is improved, effectively reducing the bending deformation of the crossbar.

[0027] Specifically, when using this adjustable multi-functional extended car roof rack, firstly, the base body 11 of the fixed base assembly 1 is engaged with the longitudinal rail 4 on the car roof through the slot of the clamping member 12, and the first bolt 14 on the clamping member 12 is rotated so that the clamping block 15 at the end of the bolt abuts against the side wall of the longitudinal rail to complete the base fixing.

[0028] According to the size of the loaded items, push the sliding block 22 to slide along the base body 11 to adjust the distance between the crossbar bodies 21. After adjustment, rotate the second bolt 23 so that the end of the bolt abuts against the base body 11 to fix the crossbar. The reinforcing rib 24 is connected between the crossbar body 21 and the sliding block 22 to enhance the structural strength.

[0029] When it is necessary to increase the loading area, pull out the positioning pin on the connecting hinge 35, unfold the folding extension platform 31 to the vertical position, and then insert the positioning pin to fix it. This allows the folding extension platform 31 to effectively block the placed items, thereby increasing the roof storage volume and ensuring the stable placement of large objects.

[0030] After use, the foldable extension platform 31 folds and is fixed by positioning pins, making it easy to store without affecting the normal driving of the vehicle.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
