[0002] When people travel by themselves, in order to conveniently place luggage, they will install a luggage rack on the roof to carry things. However, the existing luggage rack lacks the function of protecting the luggage when in use. When the vehicle shakes during driving, the luggage is easy to fall from the luggage rack. Therefore, it is necessary to design a luggage rack.

[0003] Patent application number CN216101872U discloses an automobile luggage rack expansion bracket. By sliding the stretchable expansion bracket on the slide rail, the expansion bracket can be moved to one side of the luggage bracket and extended out. The position of the expansion bracket after movement is locked and limited by adjusting bolts. Then, the telescopic sleeve provides support for laying items. The camping mattress is covered on the telescopic sleeve, and the tent bracket is connected to the luggage bracket and the expansion bracket. The luggage is placed on the luggage bracket for storage.

[0059] When people need to use the luggage rack, they can use this extendable luggage rack. First, people install the extendable luggage rack at the roof position. Then, when people need to place more luggage, people can manually move the extension plate 21 outward, so that the extension rod 31 and the guide plate 25 move outward, thereby extending the telescopic plate 24 and the telescopic frame 32. When the extension plate 21 moves outward to a suitable position, people place the luggage between the extension plate 21 and the upper part of the fixed plate 22. After placement is completed, people manually move the first card rod 35 outward.

When the extension rod 31 moves upward to a suitable position, people stop rotating the rotating card wheel 34 and manually move the first card rod 35 inward. After the rod 35 moves inward to lock the sliding block 33, people release the first clamping rod 35, thereby achieving a protective effect to prevent the luggage from falling from the extension plate 21 and the fixed plate 22 during the driving of the vehicle. When people need to take off the luggage, they move the first clamping rod 35 outward according to the above steps, and then people manually rotate the rotating clamping wheel 34 in the opposite direction to make the sliding block 33 and the extension rod 31 move downward, and the lower side of the telescopic frame 32 shortens. When the extension rod 31 moves downward to the appropriate position, people manually move the first clamping rod 35 inward according to the above steps, and then people take off the luggage on the extension plate 21 and the fixed plate 22.

Two second torsion springs 53 are connected between the extension plate 21 and the pressure rod 52 rotating thereon. There are eight second torsion springs 53. The second torsion spring 53 is wound around the pressure rod 52. The left and right sides of the fixed frame 23 are slidably connected with the cylinder 51. The cylinder 51 is fixedly connected to the guide plate 25. The telescopic rod of the cylinder 51 contacts the extension rod 31. The pressure rod 52 contacts the cylinder 51 after rotation. There are four cylinders 51. Switches are installed on the cylinder 51, and the pressure rod 52 contacts the switch.

[0063] Reference Figure 1 、 Figure 8 and Figure 9 , also includes a firm mechanism 6, the firm mechanism 6 includes a card plate 61, an adjusting rod 62 and a second card rod 63, two card plates 61 are welded on the outside of the extension rod 31, there are four card plates 61, the two front card plates 61 are slidably connected with an adjusting rod 62, and the two rear card plates 61 are slidably connected with an adjusting rod 62, and the card plates 61 are slidably connected with a second card rod 63, there are four second card rods 63, and the second card rod 63 is in contact with the adjusting rod 62.

[0065] The extension plate 21 moves outward, driving the guide frame 41 to move outward, causing the telescopic rod 42 and the sliding plate 45 to move outward, thereby causing the sliding plate 45 to move downward along the bracket 1, causing the telescopic rod 42 to rotate during the extension process, the first pressure spring 44 is stretched, and the first torsion spring 43 is torsionally deformed, thereby achieving a supporting effect to prevent the extension plate 21 from shaking. The extension plate 21 moves inward, driving the guide frame 41 to move inward, and then the telescopic rod 42 and the sliding plate 45 move inward, causing the sliding plate 45 to move upward along the bracket 1, and then the telescopic rod 42 shortens, the first pressure spring 44 resets, and the first torsion spring 43 resets, driving the telescopic rod 42 to rotate in the opposite direction.

[0066] In the initial state, the pressure rod 52 is in contact with the expansion rod 31, the second torsion spring 53 is twisted and deformed, the guide plate 25 moves outward, and the cylinder 51 moves outward. When the expansion rod 31 moves upward away from the pressure rod 52, the second torsion spring 53 returns to its original position and drives the pressure rod 52 to rotate and contact the switch on the cylinder 51, so that the cylinder 51 is turned off after five seconds of activation. The telescopic rod of the cylinder 51 is extended and contacts the expansion rod 31, thereby achieving a reinforcement effect, making the expansion rod 31 more stable. When people need to extend the rod 31 When moving downward, people manually rotate the pressure rod 52 in the opposite direction, causing the second torsion spring 53 to twist and deform. When the pressure rod 52 moves away from the cylinder 51, the telescopic rod of the cylinder 51 starts again and then shuts down after five seconds. The telescopic rod of the cylinder 51 shortens and moves away from the extension rod 31. When the pressure rod 52 rotates in the opposite direction to the appropriate position, people move the extension rod 31 downward according to the above steps, so that the extension rod 31 moves downward and contacts the pressure rod 52. People release the pressure rod 52, and the guide plate 25 moves inward, driving the cylinder 51 to move inward.

[0067] The extension rod 31 moves upward to drive the card plate 61 and the adjusting rod 62 to move upward. When people need to fix the upper part of the luggage, they manually move the second card rod 63 upward. When the second card rod 63 is pulled out, people manually move the adjusting rod 62 inward. When the adjusting rod 62 moves inward to a suitable position, people insert the second card rod 63 into the card plate 61 to fix the adjusting rod 62, thereby achieving a tightening effect to prevent the luggage from moving up and down. When people need to take out the luggage, they pull out the second card rod 63 according to the above steps, and then manually move the adjusting rod 62 outward. When the adjusting rod 62 moves outward to a suitable position, people clamp the adjusting rod 62 through the second card rod 63, and then people take out the luggage according to the above steps.

When the blocking rod 71 moves upward to the appropriate position, people release the third clamping rod 72, and the second pressure spring 73 resets and drives the third clamping rod 72 to move inward to block the blocking rod 71, thereby achieving the blocking effect and preventing small luggage from falling. When people need to move the extension rod 31 downward, people move the third clamping rod 72 outward according to the above steps, and then move the blocking rod 71 downward. When the blocking rod 71 moves downward to the appropriate position, people release the third clamping rod 72, and then people move the extension rod 31 downward according to the above steps.
