[0021] The following combination Figure 1-20 , the contents of the present invention are described in detail through specific embodiments. Example

[0022] A roof rack type folding shed includes a roof rack and a roof connector 2 for fixedly connecting the roof rack 1 and the roof of the vehicle, wherein: The roof rack includes two crossbeams 101 symmetrically arranged front and back; two vertical beams 102 fixed to the left and right sides of the upper part of the crossbeam are fixed between the crossbeams; the crossbeams and the vertical beams form a stable square frame; the left and right sides of the crossbeam are also provided with pull rods 3 that can move left and right, and the pull rods are connected to the crossbeams through telescopic slide rails 103 arranged on the inner side of the crossbeam. The connecting ends of the pull rods and the telescopic slide rails are fixedly connected by welding, so that the pull rods can be extended and contracted on the left and right sides of the crossbeam. After extension, the space on the left and right sides of the roof rack can be expanded. The width of the roof rack after expansion is greater than the width of the vehicle body, preventing the telescopic column assembly supporting the shed from interfering with the vehicle body; telescopic column assemblies 4 are provided at both ends of the pull rod, which are rotatably connected to the end of the pull rod, and the telescopic column assembly is rotationally limited with the pull rod by a rotation limit assembly 5; a limit block 6 for limiting the rotation angle of the column assembly is also fixed at the end of the pull rod; the telescopic column assembly includes a column inner tube 401, a column sleeve 402 sleeved on the outside of the column inner tube, and a column jack 403 fixedly set at the bottom of the column inner tube. After the column inner tube and the column sleeve are extended, the column inner tube and the column sleeve are limited and fixed by a pin 404. Specifically, a pin hole 405 that cooperates with the pin is provided on the column sleeve, and a plurality of holes 406 corresponding to the pin hole are arranged vertically at intervals on the column inner tube (such as Figure 12 As shown). The diameter of the column jack is the same as the diameter of the inner tube of the column. The column jack and the inner tube of the column are welded and fixed to form an integrated straight column. The column jack is used to raise the position of the roof rack after the roof rack is separated from the roof connector to prevent the roof rack from interfering with the roof connector when the vehicle is driven out of the shed. The column jack is a prior art and can be purchased. Removable tie bars 7 are provided between the telescopic column assemblies on the left, right and rear sides. The tie bars are used to stabilize the telescopic column assemblies. Connecting rings 701 are fixedly provided at both ends of the tie bars. A tie bar connector 407 is fixedly provided on the column jack to connect with the connecting ring. The tie bar connector is provided with a threaded through hole that cooperates with the bolt.

The push rod passes through the oblong hole and can move axially inside the oblong hole; when the telescopic column assembly needs to unlock the vertical state and rotate back, it is only necessary to push the push rod downward to disengage the gear teeth on the clamping column from the gear teeth of the connecting column, and then rotate the telescopic column assembly back; the retaining ring and the bolt are used to limit the C-shaped tube sleeve on the connecting column.

[0024] In order to avoid mutual interference between the telescopic column assemblies on the left and right sides when in a horizontal state, an increasing connector 301 for increasing the position height of the telescopic column group on the left is fixedly provided on the upper part of both ends of the left pull rod. The increasing connector is an L-shaped tubular structure; the telescopic column assembly on the left is rotatably connected to the increasing connector through a rotation limit assembly; in order to make the fixed positions of the four telescopic column assemblies form a rectangular distribution, the left pull rod with the increasing connector has the same length as the right pull rod.

[0025] In order to make the limit block fit tightly with the telescopic column assembly, an arc-shaped recessed structure corresponding to the shape of the column sleeve is provided on the limit block; when the telescopic column assembly is rotated to a vertical state, the column sleeve fits exactly with the arc-shaped recessed structure, realizing the vertical limitation of the telescopic column assembly.

[0026] In order to achieve the fixation and disassembly of the roof luggage rack and the roof connecting piece, fixing blocks 104 connected to the roof connecting piece with bolts are fixed on the left and right sides of the crossbeam. The bottom of the fixing block is provided with a threaded hole that cooperates with the bolt.

[0028] To create a shielding surface between the left and right telescopic column assemblies, a left shielding surface and a right shielding surface are provided between the left and right telescopic column assemblies. The left and right shielding surfaces can be folded and fixed to the inside of the pull rod. The left and right shielding surfaces have the same folding structure and are arranged symmetrically on both sides. When folded, they can be placed inside the pull rod. When unfolded, they can become a shielding surface between the telescopic column assemblies. The left and right blocking surfaces respectively include a plurality of sliding shafts 801 arranged at intervals, a folding shaft 802 arranged between the sliding shafts, a plurality of connecting plates 803 connected between the sliding shafts and the folding shafts, and bearings 805 arranged at both ends of the sliding shafts; the folding surface includes sleeves 804 fixedly provided at the upper and lower ends of the connecting plate and sleeved on the sliding shafts or folding shafts; a slide rail supporting the left and right blocking surfaces to slide up and down is provided between the telescopic column assemblies; the slide rail is a segmented structure, consisting of an upper slide rail 601, a middle slide rail 408 and a lower slide rail 409 to form a whole slide rail; the upper slide rail is fixedly connected to the limit block, and the middle slide rail is fixedly connected to the column sleeve (such as Figure 18 As shown, the lower rail is fixedly connected to the column jack; the topmost bearings of the left and right stop surfaces are fixedly mounted inside the rails of the limit block; the bearings on the left and right stop surfaces, except for the topmost bearing, slide up and down inside the rails. The column sleeve is also provided with a long opening to prevent interference between the column sleeve and the lower rail; when the telescopic column assembly drops vertically, the upper rail is connected to the middle rail; when the column sleeve and column inner tube are in a retracted state, the middle rail is connected to the lower rail; when the column sleeve and column inner tube are in an extended state, the middle rail is separated from the lower rail, and manual assistance is required to place the bearings that have slipped out of the rails into the corresponding rails during the up and down sliding process. A U-shaped piece 106 is fixedly provided on the telescopic horizontal plate, and a buckle 21 for fixing the left and right baffles in the folded state is fixedly provided on the U-shaped piece and the telescopic horizontal plate. The folded left and right baffles are fixed to the bottom of the telescopic horizontal plate (such as Figure 17 The connecting plates in each row are evenly spaced, and the connecting plates in adjacent rows are staggered. This structural arrangement design prevents interference between the connecting plates when the left or right baffle is folded. This staggered arrangement reduces the height of the left or right baffle after folding, thereby saving the space temporarily occupied by the left or right baffle after folding.

[0029] In order to form a shielding surface between the two telescopic column assemblies on the front side, a front shielding surface for shielding is provided between the telescopic column assemblies on the front side; the front shielding surface can be folded and fixed to the inner side of the crossbeam. The front shielding surface includes a square door frame 901 whose top is hinged to the crossbeam by hinges, a door body structure 902 provided inside the square door frame, and folding baffles 903 hinged on both sides of the square door frame; a foot column 904 with an up and down adjustment function is also fixedly provided at the bottom of the square door frame; a passage corresponding to the sunroof of the vehicle after the front shield is folded is provided on the door body structure and the folding baffle.

After the square door frame is folded, it can be fixed to the position below the horizontal plate by the buckle 3 (as shown). Figure 17 shown).

[0030] In order to form a shielding surface between the two telescopic column assemblies at the rear, a rear shielding surface is provided between the telescopic column assemblies at the rear; the rear shielding surface can be folded and fixed to the inner side of the crossbeam. The rear shielding surface includes a folding column 11 hinged at the top to the fixed block, a folding surface 12 provided between the folding columns, and a detachable folding surface 13 provided between the folding columns and the telescopic column assembly. The structures of the folding surface and the detachable folding surface are the same as those of the left and right shielding surfaces. The folding surface and the detachable folding surface respectively include a plurality of sliding shafts arranged at intervals, a folding shaft provided between the sliding shafts, a plurality of connecting plates connected between the sliding shafts and the folding shafts, and bearings fixed at both ends of the folding shafts. A foot column 121 with an up-and-down adjustment function is fixedly provided at the bottom of the folding column. A sleeve is fixedly provided at the upper and lower ends of the connecting plate and is sleeved on the sliding shaft or folding shaft. The sleeve can rotate on the sliding shaft or folding shaft. Slide rails are provided between the folding columns and between the folding columns and the telescopic column assembly to support the folding surface and the detachable folding surface in vertical sliding engagement. The slide rails between the folding columns are of segmented structure, and the upper slide rail 109 and the lower slide rail 122 form a whole slide rail (such as Figure 15 As shown). The upper slide rail is fixedly connected to the fixed block, and the lower slide rail is fixedly connected to the folding column. When the folding column falls vertically, the fixed block and the slide rail on the folding column are connected to form a complete slide rail; the top bearing of the folding surface is fixed in the slide rail on the fixed block, and the other bearings of the folding surface except the top bearing are slidably fitted in the slide rail. The threaded hole 19 at the bottom of the rear crossbeam fixing block is set on the folding column (as shown). Figure 16As shown), the threaded hole is connected and fixed to the roof connector by bolts. The connecting plates of each row are arranged at even intervals, and the connecting plates of two adjacent rows are arranged in a staggered manner. Such a structural arrangement design can prevent the folding surface or the detachable folding surface from interfering with each other between the connecting plates after folding. This staggered structural design reduces the height of the folding surface or the detachable folding surface after folding, and relatively saves the space temporarily used by the folding surface or the detachable folding surface after folding. A U-shaped part 111 is fixedly provided on the horizontal plate, and a buckle five 25 for fixing the folding surface in the folded state is fixed on the U-shaped part and the folding surface. After the folding surface is folded, it can be fixed to the position below the horizontal plate by the buckle five (as shown in FIG. Figure 17 shown).

[0031] The slide rail between the folding column and the telescopic column assembly is a segmented structure, which is composed of an upper slide rail 601, a middle slide rail 408 and a lower slide rail 409 to form a whole slide rail; the upper slide rail is fixedly connected to the fixed block or the limit block, the middle slide rail is fixedly connected to the folding column or the column sleeve, and the lower slide rail is fixedly connected to the folding column or the column jack; when the telescopic column assembly falls vertically, the segment slide rail on the telescopic column assembly is connected to the middle slide rail; when the column sleeve and the column inner tube are folded, ... In the retracted state, the middle slide rail on the telescopic column assembly is connected to the lower slide rail; when the column sleeve and the column inner tube are in the extended state, the middle slide rail on the telescopic column assembly is separated from the lower slide rail, so that the middle slide rail and the lower slide rail form a slide rail gap; a slide rail gap corresponding to the slide rail gap is set between the middle slide rail and the lower slide rail on the folding column; the bearing of the detachable folding surface can be placed into the slide rail through the slide rail gap until the detachable folding surface is fully unfolded into the slide rail. The bearing at the top of the detachable folding surface can be fixed in the slide rail by a latch 23, so that the top of the detachable folding surface is fixed to the slide rail (such as Figure 12 shown).

[0032] A buckle four 24 for fixing the folding column in the folded state is fixedly provided on the folding baffle and the folding column. After the folding column is folded, it can be fixed to the position below the horizontal plate by the buckle four.

[0033] In order to prevent the folding column from interfering with the rear side reinforcement, a reinforcement sleeve 702 (such as Figure 14 shown).

[0034] In order to make the roof connector better cooperate with the fixing and disassembly of the roof luggage rack, a fixing seat 201 is fixed on the roof connector to match the fixing block and the limit block. The fixing seat is provided with a hole corresponding to the threaded hole at the bottom of the fixing block to facilitate bolt connection; a matching buckle 20 is provided on the limit block and the fixing seat. The buckle 2 can prevent the retracted pull rod from extending outward (such as Figure 19As shown); a recessed structure is provided on the inner side where the limiting block and the fixed block are in contact with each other to prevent the fixed block and the limiting block from interfering with each other.

[0035] In order to fix the detachable tie rod on the roof rack, fixed pins for placing and fixing the tie rod are fixed at the front and rear positions of the top of the tie rod, and the outer side of the fixed pin is threaded; after the connecting ring of the tie rod is inserted into the fixed pin from top to bottom, the tie rod is connected to the tie rod by the nut 14 screwed into the top of the fixed pin.

[0036] In order to fix the telescopic column assembly to the roof luggage rack in the horizontal state and avoid the problem of the telescopic column assembly shaking and swinging during bumpy driving, a fixing column 15 for fixing the left telescopic column assembly is fixed on the top of the vertical beam, and the top of the fixing column is provided with a threaded hole corresponding to the threaded through hole on the tie rod connector; the fixing column and the tie rod connector can be connected and fixed by bolts to achieve the fixation of the left telescopic column assembly in the horizontal folded state; an arc-shaped recessed structure matching the right telescopic column assembly is provided on the cross beam, and the right telescopic column assembly in the horizontal folded state can fit into the arc-shaped recessed structure; an extrusion block 17 fitting into the left telescopic column assembly is also provided on the right telescopic column assembly; when the left telescopic column assembly is fixed by the fixing column and fits into the extrusion block, the right telescopic column assembly will be clamped between the left telescopic column assembly and the arc-shaped recessed structure of the cross beam, so that the right telescopic column assembly is fixed in the horizontal folded state (such as Figure 19 shown).

[0037] The left, right, front, and rear baffles, when folded and secured, do not interfere with each other and can be placed in the bottom space of the square frame. The folded roof rack height does not exceed national height requirements for roof racks. The folded left and right baffles can be placed in the inner space between the crossbeams; the folded front and rear baffles can be placed in the space below the crossbeams. The detachable folding baffles cannot be placed in the bottom space of the square frame and require additional storage space.
