[0024] Example 1: like Figure 1-7 As shown, a vehicle luggage rack includes a frame and a climbing assembly. The frame is mounted on the roof of the vehicle. The frame includes a fixed frame 1, an adjustable frame 21, and an adjusting assembly. The fixed frame 1 is fixed to the frame. Both the fixed frame 1 and the adjustable frame 21 are C-shaped. The adjusting assembly is located between the fixed frame 1 and the adjustable frame 21 and is used to adjust the distance between the fixed frame 1 and the adjustable frame 21. like Figure 8 As shown, the climbing assembly is mounted on the fixed frame 1. The climbing assembly includes a storage tube 4, a telescopic tube 6, a telescopic rod 7, and several pedals 8. The two ends of the storage tube 4 are fixed to the two ends of the fixed frame 1, and one end of the storage tube 4 has an extension port 5. One end of the telescopic tube 6 is telescopically connected to the storage tube 4 through the extension port 5. Both sides of the storage tube 4 have sliding grooves, and the end of the sliding groove facing the extension port 5 has an anti-detachment block. Both sides of the telescopic tube 6 have flip pins 22 that slide in cooperation with the sliding grooves. The anti-detachment blocks are used to limit the flip pins 22 in the sliding grooves. The telescopic rod 7 is telescopically connected to the end of the telescopic tube 6 away from the storage tube 4. The pedals 8 are rotatably connected to the side of the telescopic tube 6 and the side of the telescopic rod 7 through a pivot 10.

[0025] Both the adjusting frame and the fixing frame 1 have protrusions in the middle to block and hold luggage, facilitating luggage positioning and subsequent luggage binding and securing. The fixing frame 1, sliding sleeve 3, storage tube 4, connecting rod 11, fixing rod 12, and positioning plate 13 are all fixed by plugging or welding to form the first component. The side rod 2, adjusting rod 14, guide plate 15, insert plate 16, and adjusting frame 21 are all fixed by plugging or welding to form the second component. During installation, the first component is directly fixed to the roof with bolts. Then, two fixing seats 17 are fixed to the roof with bolts. Then, the second component is connected to the first component, where the side rod 2 cooperates with the sliding sleeve 3, the guide plate 15 is inserted into the adjusting groove, and finally, the telescopic rod 7 and telescopic tube 6 are installed into the storage tube 4. The installation opening is sealed by the mounting block to achieve complete assembly. In addition, the adjusting frame 21 can also be provided with bolt holes so that after the adjusting frame 21 is moved into place, bolts can be inserted to fix the adjusting frame 21 to the roof.

[0026] When in use, simply pull the adjustment frame 21. Guided by the adjustment unit, the distance between the adjustment frame 21 and the fixed frame 1 can be adjusted adaptively according to the amount of luggage. When climbing is required, simply pull out the telescopic tube 6 and the telescopic rod 7, flip out the footboard 16, and then rotate the telescopic tube 6 downwards with the flip pin 22 as the center so that the bottom end of the telescopic rod 7 supports the ground, thus forming a simple ladder.

[0027] The vehicle luggage rack of this embodiment adopts a climbing component. When in use, the user can pull out the telescopic tube 6 and the telescopic rod 7, and flip it down so that the telescopic rod 7 supports the ground. The simple ladder formed after flipping down the foot pedal 8 allows the user to quickly climb up and down, making it convenient for the user to load and unload luggage and saving physical strength. Moreover, the use of the adjustment component can pull the adjustment frame 21 to move relative to the fixed frame 1, realizing the quick adjustment of the distance between the fixed frame 1 and the adjustment frame 21, so as to make adaptive adjustments according to the amount of luggage, which has good adaptability.

[0028] The adjustment assembly includes several fixed rods 12, several adjusting rods 14, and two guide units. The fixed rods 12 are evenly fixed on the side of the storage tube 4 facing the adjustment frame 21, and the adjusting rods 14 are fixed on the side of the adjustment frame 21 facing the fixed frame 1. The adjusting rods 14 are located between two adjacent fixed rods 12. Each fixed rod 12 has an adjustment groove on both sides, and each adjusting rod 14 has a guide piece 15 that slides into the adjustment groove on both sides. The two guide units are located at both ends of the fixed frame 1, and the guide units connect the fixed frame 1 and the adjustment frame 21. Several connecting rods 11 are provided between the fixed frame 1 and the storage tube 4, and the two ends of the connecting rods 11 are fixed to the fixed frame 1 and the storage tube 4, respectively.

[0029] The fixing rod 12 is fixed on the storage tube 4. Since the fixing frame 1 is fixed on the roof of the vehicle, multiple fixing rods 12 form a sliding channel. With the help of the guide plate 15, the adjusting rod 14 can slide smoothly along the sliding channel. Furthermore, two adjacent fixing rods 12 can limit the adjusting rod 14.

[0030] A positioning plate 13 is provided at the end of the fixing rod 12 away from the storage tube 4. The positioning plate 13 is set perpendicular to the fixing rod 12, and the end of the fixing rod 12 is fixed to the positioning plate 13 by bolts. The positioning plate 13 can fix the ends of multiple fixing rods 12 away from the storage tube 4, ensuring that the distance between adjacent fixing rods 12 remains unchanged. Moreover, the positioning plate 13 can also assist in supporting the adjusting rod 14.

[0031] The adjusting rod 14 is provided with a plate 16, the two ends of which are fixed to the two ends of the adjusting frame 21, and the plate 16 passes through the adjusting rod 14 in sequence. The plate 16 can connect the adjusting rods 14 in series to prevent the distance between adjacent adjusting rods 14 from changing.

[0032] The guiding unit includes a side rod 2 and a sliding sleeve 3. The sliding sleeve 3 is fixed to the end of the fixed frame 1. One end of the side rod 2 is fixed to the end of the adjusting frame, and the other end of the side rod 2 is slidably fitted inside the sliding sleeve 3. The outer wall of the side rod 2 is provided with several guide strips 20, and the inner wall of the sliding sleeve 3 is provided with several guide grooves 18 that slidably fit with the guide strips 20. The side rod 2 and the sliding sleeve 3 can connect the end of the fixed frame 1 and the end of the adjusting frame 21, so that the fixed frame 1, the adjusting frame 21 and the two guiding units form a rectangular support structure, which provides better support for luggage and prevents luggage from tilting.

[0033] The vertical cross-section of the sliding sleeve 3 is C-shaped and is fitted onto the side of the side rod 2 away from the adjusting rod 14. A positioning strip 19 is provided in the middle of the other side of the side rod 2. The positioning strip 19 is arranged parallel to the side rod 2. A fixing seat 17 is provided on the side of the side rod 2 facing the adjusting rod 14. The fixing seat 17 is fixed to the roof of the vehicle by bolts. The positioning strip 19 is slidably engaged with the fixing seat 17. The fixing seat 17 can cooperate with the C-shaped sliding sleeve 3 to hold the two sides of the side rod 2, ensuring the smooth movement of the side rod 2.

[0034] The storage tube 4 has an installation port at one end relative to the storage opening. The installation port is detachably connected to an installation block, which is used to confine the telescopic tube 6 inside the storage tube 4. The installation port and the installation block allow the telescopic tube 6 to be quickly inserted into and removed from the storage tube 4, making it convenient to replace the telescopic tube 6.

[0035] Limiting blocks are provided on both inner walls of the telescopic tube 6 at the end away from the storage tube 4. The limiting blocks are slidably engaged with the limiting grooves, which are located on both sides of the telescopic rod 7. A limiting plate is provided at the end of the limiting groove facing the storage tube 4. The limiting plate is used to prevent the limiting blocks from disengaging from the limiting groove. The two ends of the rotating shaft 10 are rotatably connected to the two sides of the limiting groove. A stop bar is provided below the rotating shaft 10. The stop bar is used to support the pedal 8. The setting of the limiting plate can prevent the telescopic rod 7 from disengaging from the telescopic tube 6. The setting of the stop bar can make the pedal 8 perpendicular to the telescopic tube 6 or the telescopic rod 7 when it is lowered, which is convenient for the user to step on and climb.

[0036] The pedal 8 is equipped with anti-slip stripes. The anti-slip stripes can increase the friction between the user's foot and the pedal 8, thereby making it easier for the user to step on and climb, and preventing the user's feet from slipping.

[0037] The telescopic rod 7 is provided with support plates 9 on both sides of the end away from the telescopic tube 6. The support plates 9 are rotatably connected to the telescopic rod 7 via a rotating shaft 10.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way.
