This device is usually used for hatchback wagons, SUVs, MPVs and other vehicle models to securely and conveniently fix luggage. The design of the roof luggage takes into account both practicality and aesthetics. It can not only help the car owner carry more items, but also change the appearance of the car to some extent, making it look more fashionable.

[0003] Based on the above, the inventor found the following problems: The current roof luggage is generally installed on the roof by adding a luggage rack, and then the roof luggage is installed on the luggage rack. The disassembly and assembly process is cumbersome during use.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a roof luggage connection device without a bracket is provided, with the aim of achieving a more practical value. Content of the Utility Model

[0005] The purpose of the utility model is to provide a roof luggage connection device without a bracket to solve the problems raised in the above background technique.

[0006] In view of the above problems, the technical solution proposed by the utility model is:

[0007] A roof luggage connection device without a bracket includes a roof luggage body, a connection mechanism and an auxiliary mechanism. The roof luggage body includes a housing. A pair of installation grooves are opened inside the bottom end of the housing. The connection mechanism includes a pair of installation strips. The pair of installation strips are respectively arranged inside the pair of installation grooves, and the outer walls of the pair of installation strips are respectively connected to the inner walls of the pair of installation grooves. A pair of round holes are respectively opened in the inner parts of the pair of installation strips near both ends. Permanent strong magnets are connected inside the pair of round holes. The auxiliary mechanism includes a first connection belt. The first connection belt is in an "X" shape, and the bottom end of the first connection belt is attached to the top surface of the housing, and second connection belts are connected to the outer walls of the four corners of the first connection belt.

[0008] Furthermore, the bottom ends of the permanent strong magnets all penetrate through the round holes and extend to the outside, and rubber sleeves are sleeved outside the bottom ends of the permanent strong magnets.

[0009] The beneficial effect of adopting the above further solution is that by setting a permanent strong magnet, the permanent strong magnet can be adsorbed to the vehicle roof, so as to facilitate the adsorption of the roof luggage on the roof. At the same time, by sleeving a rubber sleeve outside the bottom end of the permanent strong magnet, the setting of the rubber sleeve will not affect the magnetic adsorption of the permanent strong magnet, and will not damage the paint on the roof.

[0010] Further, the number of the second connecting belts is four. Connecting seats are arranged on the outsides of the four second connecting belts. Fixed seats are connected to the opposite sides of a pair of the connecting seats on the same side. Slots and square grooves are respectively formed on both sides of the inner wall of the fixed seat. An inserting block is slidably arranged inside the square groove, and the size of the inserting block is smaller than that of the slot.

[0011] The beneficial effect of adopting the above further solution is that through the cooperation of the inserting block and the slot, when one end of the second connecting belt passes through the pull handle of the vehicle inner door, the end of the second connecting belt is passed through the fixed seat, and then the end of the second connecting belt is pulled hard, so that the inner wall of the second connecting belt is closely attached to the outer wall of the pull handle of the vehicle inner door. At the same time, since the size of the slot is larger than that of the inserting block, when the inserting block moves towards the slot, it is convenient to drive the second connecting belt in the fixed seat to move towards the slot. When the inserting block is engaged with the slot, the second connecting belt in the fixed seat enters the inside of the slot, so that a part of the second connecting belt is located between the inserting block and the slot.

[0012] Further, a cavity is arranged inside the fixed seat close to the square groove. A sliding groove is arranged on one side of the inner wall of the cavity. A pair of sliding blocks are slidably connected inside the sliding groove. A bidirectional screw rod is rotatably connected inside the cavity. Two ends of the bidirectional screw rod respectively penetrate through the pair of sliding blocks and extend to the outside, and are respectively slidably connected between the pair of sliding blocks.

[0013] The beneficial effect of adopting the above further solution is that by arranging the cavity, it is convenient to install the bidirectional screw rod. When the bidirectional screw rod rotates, it is convenient for the sliding blocks on the opposite threads outside its two ends to move towards each other under the sliding action with the sliding groove.

[0014] Further, one ends of the pair of sliding blocks away from the sliding groove are respectively connected with a first hinge seat. A connecting rod is hinged to the outsides of the pair of first hinge seats. Second hinge seats are respectively hinged to one ends of the pair of connecting rods away from the first hinge seats. One side of the pair of hinge seats is connected with the side of the inserting block away from the slot.

[0015] The beneficial effect of adopting the above further solution is that when the pair of sliding blocks move towards the center in opposite directions, the connecting rod will push the inserting block under the hinge action of the first hinge seat and the second hinge seat.

[0016] Further, a U-shaped seat is connected to the outer side walls of the fixed seat and the connecting seat. One end of the bidirectional screw penetrates through the U-shaped seat and extends to the inside, and is connected to the inner side wall of the U-shaped seat through a bearing. A worm gear is sleeved on the outside of one end of the bidirectional screw. A worm is rotatably connected inside the U-shaped seat near the worm gear, and the worm meshes with the worm gear.

[0017] The beneficial effect of adopting the above further solution is that on the opposite sides of a pair of fixed seats in the same horizontal direction, a U-shaped seat is connected to each. The number of U-shaped seats is the same as that of the second connecting belts, which is four. By using the cooperation of the worm gear and the worm, when the worm rotates, it drives the worm gear to rotate, and then the rotation of the bidirectional screw is realized.

[0018] Further, the upper end of the worm penetrates through the U-shaped seat and extends to the outside, and a knob is sleeved on it.

[0019] The beneficial effect of adopting the above further solution is that by setting the knob, when the knob is rotated, it is convenient to realize the rotation of the worm.

[0020] Further, the first connecting belt and the four second connecting belts are all made of nylon material. Adjusting buckles are provided above the connecting seats on the outside of the four second connecting belts.

[0021] The beneficial effect of adopting the above further solution is that by making the first connecting belt and the four second connecting belts of nylon material, the first connecting belt and the four second connecting belts have the ability to resist tensile force. By setting adjusting buckles on the outside of the four second connecting belts, it is convenient to adjust the telescopic amount of the connecting seats on the second connecting belts according to actual needs.

[0022] Compared with the prior art, the beneficial effect of the present utility model is that for this roof luggage rack connection device without a bracket, by providing an installation groove at the bottom end of the housing, it is convenient to install the installation strip in the installation groove. By setting a permanent strong magnet, the permanent strong magnet can adsorb to the vehicle roof, so as to conveniently adsorb the roof luggage rack on the roof of the vehicle, solving the problem that the traditional connection between the roof and the luggage rack requires a luggage rack as a connection method, avoiding the cumbersome process of disassembly and assembly during use, being simple and fast without tools. At the same time, by sleeving a rubber sleeve on the outside of the bottom end of the permanent strong magnet, the setting of the rubber sleeve will not affect the magnetic adsorption of the permanent strong magnet, and will not damage the paint on the vehicle roof. By setting the first connecting belt, the first connecting belt is in an X shape, which is convenient to cooperate with the four second connecting belts to assist in fixing the luggage rack, improving the stability of the roof luggage rack during driving.

[0035] Specifically, the working principle of this roof luggage rack connection device without a bracket: During use, by setting an installation groove 1002 at the bottom end of the housing 1001, it is convenient to install the installation strip 2001 in the installation groove 1002. By setting a permanent strong magnet 2002, the permanent strong magnet 2002 can adsorb to the vehicle roof, thus facilitating the adsorption of the roof luggage rack body 100 on the roof. This solves the problem that the traditional connection between the roof and the luggage rack requires a luggage rack as the connection method, avoiding the cumbersome process of disassembly and assembly during use. It is simple, fast, and tool-free. At the same time, by sleeving a rubber sleeve 2003 outside the bottom end of the permanent strong magnet 2002, the setting of the rubber sleeve 2003 will not affect the magnetic adsorption of the permanent strong magnet 2002, and will not damage the paint on the roof. By setting a first connecting belt 3001 in an X shape, it is convenient to cooperate with four second connecting belts 3002 to assist in fixing the roof luggage rack body 100, improving the stability of the roof luggage rack body 100 during driving. When one end of the second connecting belt 3002 passes through the grab handle of the vehicle inner door, pass one end of the second connecting belt 3002 through the fixing seat 3004, and then pull the end of the second connecting belt 3002 forcefully, so that the inner wall of the second connecting belt 3002 is closely attached to the outer wall of the grab handle of the vehicle inner door. When turning the knob 3015, it is convenient to rotate the worm 3014, drive the worm wheel 3013 to rotate, and then rotate the bidirectional screw 3009, facilitating the opposite movement of the sliders 3008 on the opposite threads outside its two ends under the sliding action of the sliding grooves 3007. When a pair of sliders 3008 move towards the center, the connecting rod 3010 will push the plug 3006 under the hinge action of the first hinge seat and the second hinge seat 3011. Since the size of the slot 3005 is larger than the size of the plug 3006, when the plug 3006 moves towards the slot 3005, it is convenient to drive the second connecting belt 3002 in the fixing seat 3004 to move towards the slot 3005. When the plug 3006 engages with the slot 3005, the second connecting belt 3002 in the fixing seat 3004 enters the inside of the slot 3005, making a part of the second connecting belt 3002 located between the plug 3006 and the slot 3005. By setting the first connecting belt 3001 and the four second connecting belts 3002 to be made of nylon material, the first connecting belt 3001 and the four second connecting belts 3002 have the ability to resist tensile forces. By setting adjustment buckles 400 outside the four second connecting belts 3002, it is convenient to adjust the telescopic amount of the connecting seat 3003 on the second connecting belt 3002 according to actual needs.
