DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] The present invention will be further explained in conjunction with the drawings.

[0025] Example 1 1 to 18, the roof-lifting luggage rack includes a sliding frame 1, a sliding seat 2, a positioning device, a link device, a storage rod 51, a fixed lock hook 61, an auxiliary wheel 71, and a second torsion spring 64. The sliding frame 1, the sliding seat 2, the positioning device, the link device, the fixed lock hook 61, the auxiliary wheel 71, and the second torsion spring 64 are the same in number.

[0026] Two sliding frames 1 are provided symmetrically and fixed to the roof. The sliding frame 1 is provided with a sliding groove 11, the cross section of which is in the shape of a concave letter "K". One end of the sliding groove 11 is provided with a limiting baffle plate 12, and the other end is provided with a locking hole 13. The locking hole 13 includes a first locking hole 131 and a second locking hole 132.

[0027] Sliding wheels 21 are symmetrically mounted on both sides of the sliding seat 2, and there are two or more sliding wheels 21 on each side, and the sliding wheels 21 are movably inserted into both sides of the sliding groove 11. The sliding wheels 21 facilitate the push-pull of the sliding seat 2, and change the sliding friction into rolling friction.

[0028] The storage rod 51 is provided with limit sliders 511 symmetrically on both sides thereof, and the storage rod 511 has a "convex" shape. The storage rod 51 is movably inserted into the sliding groove 11, and the limit sliders 511 and the sliding groove 11 are fitted together to limit the up-down and left-right positions of the storage rod 51, and fix the storage rod 51 in the sliding groove 11. Two storage rods 51 are provided symmetrically. The top of the storage rod 51 is provided with a fixing groove 512, which is a "T" shaped groove, and a flat plate or link for placing an article can be attached to the fixing groove 512 by a nut and a screw, or an article can be directly fixed in the fixing groove 512 by a connecting device.

[0029] The number of the link devices is the same as the number of the sliding frames 1, and the link devices include a first link 41, a second link 42, a third link 43, and an air tension spring 46. One end of the first link 41 is rotatably attached to the sliding seat 2 and is provided with a jack rod 45, and the other end is rotatably connected to one end of the third link 43. The second link 42 is installed parallel to one side of the first link 41, one end of the second link 42 is rotatably attached to the sliding seat 2, and the other end is rotatably attached to one end of the third link 43. The other end of the third link 43 is fixed to one end of the storage rod 51. The sliding seat 2, the first link 41, the second link 42, and the third link 43 constitute a four-bar link mechanism. Both ends of the air tension spring 46 are connected to one end of the first link 41 and the other end of the second link 42, that is, the air tension spring 46 is connected to two diagonals of the four-bar link mechanism, and provides tension when the four-bar link expands or contracts. The third link 43 is made of a plate material and has a U-shaped cross section, and the first link 41 and the second link 42 are stored inside, so that the volume occupied by the four-bar link mechanism can be reduced. Reinforcing links 49 are attached to the two third links 43, and two reinforcing links 49 are provided, and both ends of the reinforcing links 49 are connected to the two third links 43, respectively, to form the overall structure and to increase strength. When the storage rod 51 is in the stored state, the four-bar link contracts, and the air tension spring 46 pulls the first link 41 and the second link 42 to close them. In addition, both ends of the air tension spring 46 are located on both sides of the diagonal of the four-bar link, respectively, and the air tension spring 46 plays a role in locking the first link 41 and the second link 42 and maintaining the closed state.When the storage rod 51 is in the open state, the air tension spring 46 pulls the first link 41 and the second link 42. The first link 41 and the second link 42 are also in the closed state. Moreover, since both ends of the air tension spring 46 are located on both sides of the diagonal line of the four-bar link, the air tension spring 46 plays a role in locking the first link 41 and the second link 42 and maintaining the closed state. Because the first link 41 and the second link 42 are closed, the four-bar link mechanism cannot continue to invert downward. The air tension spring 46 neither contracts upward nor moves downward, maintaining the four-bar link mechanism as it is, fixing the height of the storage rod 51, which is convenient for putting items in and taking them out.

[0030] The positioning device includes a first locking hook 31, a first torsion spring 35, and a second locking hook 32. The first locking hook 31 is rotatably mounted on the sliding seat 2 via a first rotating shaft 34. The top of the first locking hook 31 is located below the jack rod 45, and the bottom of the first locking hook 31 slides and is pressed against the bottom of the sliding groove 11. One end of the second locking hook 32 is rotatably mounted on the first rotating shaft 34, and the other end of the second locking hook 32 slides and is located at the bottom of the sliding groove 11. The first locking hook 31 and the second locking hook 32 form a "V" shape. The first torsion spring 35 is movably inserted into the first rotating shaft 34. One end of the first torsion spring 35 is connected to the first locking hook 31, and the other end is connected to the second locking hook 32. The first torsion spring 35 is used to movably press both the first locking hook 31 and the second locking hook 32 against the bottom of the sliding groove 11. One locking hole 13 may be provided, and the first locking hook 31 and the second locking hook 32 are inserted on both sides of the locking hole 13 respectively.

[0031] The fixed lock hook 61 is rotatably mounted on the other end of the storage rod 51 via a fixed shaft 63, and a second torsion spring 64 is mounted on the fixed shaft 63. One end of the second torsion spring 64 is connected to the storage rod 51, and the other end is connected to the fixed lock hook 61, which is used to press the fixed lock hook 61 to the bottom of the sliding groove 11. When the sliding seat 2 abuts against the limiting baffle plate 12, it is inserted into the first lock hole 131 to lock the storage rod 51. The tail of the fixed lock hook 61 is fixed to the unlocking pressing plate 65, and when the unlocking pressing plate 65 is pressed down, the fixed lock hook 61 leaves the locking hole 13 to realize the unlocking, and the second torsion spring 64 presses the fixed lock hook 61 to the first lock hole 131 in the free state.

[0032] Both ends of the connecting tie bar 55 are respectively connected to the storage rod 51 and are used to pull the storage rod 51. By pulling the connecting tie bar 55, the two storage rods 51 can be pulled, which facilitates use and increases the connection strength between adjacent storage rods 51.

[0033] The auxiliary wheel 71 is rotatably mounted on the auxiliary frame 72 , which is fixed to the bottom of the other end of the sliding frame 1 and is used to support the sliding seat 2 and the storage rod 51 .

[0034] 7 to 18, when placing an item, the connecting tie bar 55 is pressed down, and the connecting tie bar 55 flips the fixed lock hooks 61 at both ends upward, and the fixed lock hooks 61 are released from the first lock holes 131, and the connecting tie bar 55 is pulled outward, so that the storage rod 51 and the sliding seat 2 slide to one side of the automobile, and the first lock hook 31 and the second lock hook 32 both slide in the sliding groove 11. When the sliding seat 2 moves to the other end of the sliding groove 11, the second lock hook 32 is inserted into the first lock hole 131, and the sliding seat 2 cannot continue to slide outward of the automobile. When the connecting tie bar 55 is pulled continuously and the pulling force is greater than the pulling force of the air tension spring 46, the storage rod 51 moves down while moving the third link 43 outward, and moves down to one side of the car through the four-bar link mechanism, and is at the waist position of the human body, and always maintains a horizontal state during the descent process, and the air tension spring 46 provides a pulling force, so that the storage rod 51 is always lifted with an upward force when it is lowered, preventing the storage rod 51 from falling freely, and improving safety and reliability. When the storage rod 51 is lowered, the jack rod 45 of the first link 41 gradually moves away from the top of the first locking hook 31 during rotation, and the first locking hook 31 is inserted into the second locking hole 132 by the action of the first torsion spring 35, realizing the locking of the sliding seat 2, and the sliding seat 2 cannot move along the sliding groove 11. After the article is fixed on the storage rod 51, the storage rod 51 is pushed upward until it is located at one end of the sliding frame 1, and the storage rod 51 moves upward due to the air tension spring 46 and the push of a person, the jack rod 45 presses the top of the first locking hook 31 again, the first locking hook 31 is pushed up and released from the second locking hole 132, and the storage rod 51 is pushed toward the limiting baffle plate 12, the second locking hook 32 leaves the first locking hole 131, and the second locking hook 32 slides along the bottom of the sliding groove 11 until the end of the sliding seat 2 abuts against the limiting baffle plate 12, at this time the fixed locking hook 61 moves to just above the first locking hole 131 and is inserted into the first locking hole 131 under the action of the second torsion spring 64, and the storage rod 51 and the sliding seat 2 are fixed to the sliding frame 1.

[0035] When the goods and storage rod 51 is turned over to the top of the car, the air tension spring 46 provides a tension force and reduces the upward pushing force, so that even one person can easily lift the goods to the top of the car. When the goods and storage rod 51 is lowered, it plays a damping effect, slows down the lowering speed of the goods and storage rod 51, plays a good buffering effect, and is highly safe.

[0036] Example 2 The two fixed lock hooks 61 are connected through a connecting tie bar 55. When the connecting tie bar 55 is pulled, the storage rod 51 can be slid and unlocked, which facilitates use.

[0037] Example 3 As shown in Fig. 19, a limiting baffle plate 12 is provided in the center of the sliding groove 11, and a locking hole 13 is provided at both ends of the sliding groove 11. Two sliding seats 2 are provided, one on each side of the limiting baffle plate 12, forming two sets of lifting luggage racks, which are respectively located on both sides of the top of the car. The two sliding seats 2 share one sliding frame 1. The two sets of lifting luggage racks make it easier to take in and out items from both sides of the car, and more items can be loaded.

[0038] 20 to 22 are schematic diagrams showing how to attach a bicycle, a rubber boat, and a suitcase, respectively.

[0039] The technical principle of the present invention has been described above in conjunction with specific embodiments. These descriptions are merely for understanding the principle of the present invention, and cannot be construed as limiting the protection scope of the present invention in any manner.
