The fixed rod 11 is arranged inside the car roof rack body 1 to provide a moving space for the push rod 5. The first spring 12 is arranged on the outer periphery of the fixed rod 11 to reset the movement of the push rod 5.

[0033] A support component is arranged at the bottom of the extended roof rack 2, a fixing component is arranged at the bottom of the extended roof rack 2, and a handle 4 is fixedly connected to the front end of the extended roof rack 2.

[0034] Specifically, the support component is used to support the extended luggage rack 2, and the fixing component is used to fix the support component inside the extended luggage rack 2. A handle 4 is provided on the extended luggage rack 2 for the operator to better move the extended luggage rack 2.

[0035] Reference Figure 4 and Figure 6 In this embodiment, the support component includes two support rods 13. Both support rods 13 are rotatably connected to the bottom of the extended luggage rack 2. An extension rod 18 is slidably connected to one end of each of the two support rods 13 away from the extended luggage rack 2. A threaded rod 19 is rotatably connected inside each of the two support rods 13. The two threaded rods 19 are respectively threadedly connected inside the two extension rods 18. A worm gear 20 is fixedly connected to the outer periphery of the threaded rod 19. A worm 21 is rotatably connected inside the support rod 13. The worm gear 20 and the worm 21 are meshed with each other. A turning handle 22 is fixedly connected to the front end of each of the two worms 21.

[0036] Specifically, the support rod 13 is arranged at the bottom of the extended luggage rack 2 to support the extended luggage rack 2 that extends out. An extension rod 18 is arranged inside the support rod 13 to adjust the distance that the extension rod 18 extends out, so as to support the extended luggage rack 2 at different heights. A threaded rod 19 is arranged inside the support rod 13. The threaded rod 19 cooperates with the extension rod 18, so that when the threaded rod 19 rotates, it will drive the extension rod 18 to move. A worm gear 20 is arranged on the threaded rod 19, and a worm 21 is arranged inside the support rod 13 to make the worm 21 drive the worm gear 20 to rotate when it rotates, so that the threaded rod 19 rotates. A turning handle 22 is arranged at the front end of the worm 21 for the operator to rotate the worm 21.

[0037] Reference Figure 4 - Figure 5 In this embodiment, the fixing component includes two fixing frames 14. Both fixing frames 14 are fixedly connected to the bottom of the extended luggage rack 2. A clamping block 15 is slidably connected inside each of the two fixing frames 14. A second spring 16 is fixedly connected inside each of the two fixing frames 14. The two second springs 16 are respectively fixedly connected to the rear ends of the two clamping blocks 15. A limiting block 17 is fixedly connected to the rear end of the clamping block 15. The limiting block 17 is slidably connected inside the fixing frame 14.

[0038] Specifically, the fixing frame 14 is fixed below the extended luggage rack 2 to support the internal structure. A clamping block 15 is arranged inside the fixing frame 14 to clamp the support rod 13 inside the extended luggage rack 2. A second spring 16 is arranged inside the fixing frame 14 to reset the movement of the clamping block 15. A limiting block 17 is arranged at the rear end of the clamping block 15 to prevent the clamping block 15 from being pushed out of the fixing frame 14 by the second spring 16.

[0039] Working principle and usage process of the utility model: When it is necessary to open the extended luggage rack 2 to support the tent, the operator needs to first press the pressing rod 5. Pressing the pressing rod 5 will drive the support frame 6 to move. The support frame 6 will drive the sliding frame 8 to move through the connecting rod 7. The sliding frame 8 will drive the sliding rod 9 to leave the current card slot 3, so that the extended luggage rack 2 loses restraint. Then, the extended luggage rack 2 can be pulled out by pulling the handle 4. When it is fully unfolded, release the force on the pressing rod 5, so that the first spring 12 releases tension and restores the pressing rod 5, thereby making the sliding rod 9 snap into the current card slot 3, and the unfolded extended luggage rack 2 is fixed in the current position. Then, the top of the tent can be fixed by the extended luggage rack 2.

[0040] When the tent is too heavy and it is necessary to support the extended luggage rack 2, the block 15 needs to be inserted into the fixing frame 14 first, and then the support rod 13 is taken out to support the ground. When the height is not appropriate, rotate the handle 22 to drive the worm 21 to rotate, thereby driving the worm gear 20 to rotate, making the threaded rod 19 rotate, and then the extension rod 18 extends out of the support rod 13, so that the length of the support rod 13 matches the current height, improving the versatility. When the support is not needed, rotate the handle 22 in reverse to retract the extension rod 18 into the support rod 13, and then rotate the support rod 13 into the extended luggage rack 2. Due to the shape of the block 15, when the support rod 13 moves, the block 15 will be squeezed into the fixing frame 14. When the support rod 13 completely enters the extended luggage rack 2, the second spring 16 will release tension and hold the block 15 against the support rod 13 to prevent the support rod 13 from falling.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the utility model and are not used to limit the utility model. Although the technical solutions described in the foregoing embodiments have been described in detail with reference to the utility model, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
