Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a roof rack-style folding canopy. Background Technology

[0002] In modern transportation and tourism, roof racks are a common automotive accessory widely used on various vehicle models, primarily for carrying extra luggage, equipment, or other items. Roof racks are typically secured to the roof via roof connectors, a design that ensures the rack can stably support heavy loads and transport them safely. However, traditional roof rack designs are limited to serving as a carrying platform, lacking versatility.

[0003] Especially in outdoor activities or tourist areas, users often need to set up temporary sheltered structures for rest or commercial purposes, such as selling goods. In this case, if the vehicle's roof rack could be transformed into a detachable and easily assembled canopy structure, its practicality and convenience could be greatly improved.

[0004] Most roof racks on the market do not have the function of being converted into independent canopies. This means that if users want to build a temporary canopy outdoors, they need to bring special building tools and materials, which increases the burden and preparation time.

[0005] In view of the above, it is necessary to develop a new type of roof rack folding canopy that can not only be folded into a roof rack when not in use, but also be transformed into a stable and reliable independent canopy structure when in use, to meet the needs of users for rest or business purposes. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a roof rack-style folding canopy, which can be converted into a canopy structure that is separate from the car. When the canopy is not in use, it can be folded into a roof rack and fixed to the roof of the vehicle.

[0018] The beneficial effects and features of this utility model are as follows:

[0019] This invention allows a traditional roof rack to be easily converted into an independent canopy structure. Considering the limitations of the length, width, and height of the roof rack, the design pays special attention to space management during the conversion process. For example, it employs mechanisms such as retractable rods, rotation limit components, and retractable column components to ensure that there is no collision or friction with other parts of the vehicle during the conversion. The retractable column components and bracing structure enable the canopy structure to stand stably on the ground. The canopy's coverage can be expanded by adding front, rear, left, and right side panels. When the canopy structure is not in use, all components can be easily folded and fixed to the roof rack, taking up little space. Attached Figure Description

Detailed Implementation

[0042] The following combination Figure 1-20 The contents of this utility model will be described in detail through specific embodiments. Example

[0043] A roof rack type folding canopy includes a roof rack and a roof connector 2 for fixing the roof rack 1 to the roof of the vehicle, wherein:

[0044] The roof rack includes two symmetrically arranged crossbeams 101; two vertical beams 102 are fixedly installed between the crossbeams on the upper left and right sides; the crossbeams and vertical beams form a stable square frame; and on the left and right sides of the crossbeams, there are movable pull rods 3, which are connected to the crossbeams via telescopic slide rails 103 located inside the crossbeams. The connection between the pull rods and the telescopic slide rails is fixed by welding, allowing the pull rods to extend and retract on the left and right sides of the crossbeams. When extended, the space on the left and right sides of the roof rack can be expanded. The extended width of the roof rack is greater than the width of the vehicle body to prevent interference between the telescopic support column assembly and the vehicle body. Telescopic support column assemblies 4 are rotatably connected to the ends of the pull rod at both ends. These assemblies are limited in rotation by a rotation limiting assembly 5. A limiting block 6 is also fixedly installed at the end of the pull rod to limit the rotation angle of the support column assembly. The telescopic support column assembly includes an inner column tube 401, a column sleeve 402 fitted over the inner column tube, and a column-shaped jack 403 fixedly installed at the bottom of the inner column tube. After the inner column tube and column sleeve are extended, they are fixed in place by a pin 404. Specifically, the column sleeve has a pin hole 405 that mates with the pin, and the inner column tube has multiple holes 406 arranged vertically at intervals corresponding to the pin hole (e.g., ...). Figure 12 (As shown). The diameter of the column jack is the same as the diameter of the inner tube of the column. After the column jack and the inner tube of the column are welded and fixed, they become a single straight column. The column jack is used to raise the position of the roof rack after it is separated from the roof connector, to prevent interference between the roof rack and the roof connector when the vehicle is driven out of the canopy area. The column jack is existing technology and can be purchased. Removable tie rods 7 are provided between the telescopic column assemblies on the left, right and rear sides. The tie rods are used to stabilize the telescopic column assemblies. Connecting rings 701 are fixed at both ends of the tie rods. Tie rod connectors 407 that connect and cooperate with the connecting rings are fixed on the column jacks. The tie rod connectors have threaded through holes that cooperate with bolts. The connecting rings are fixedly connected to the tie rod connectors by bolts.

[0045] To achieve rotation and limiting of the telescopic column assembly on the tie rod, the rotation limiting component 5 includes a connecting column 501, a C-shaped sleeve 502, a fixing post 503, a spring 504, a locking post 505, a retaining ring 506, and a bolt 507. The connecting column and the locking post are provided with mating gear teeth. The C-shaped sleeve is movably fitted onto the outside of the connecting column, and the end of the C-shaped sleeve is welded and fixed to the end of the column sleeve. The fixing post is fixed inside the column sleeve. Both ends of the spring are fixedly connected to the fixing post and the locking post, respectively. The locking post moves up and down inside the column sleeve. The rotation limiting component is used to limit the rotation of the telescopic column assembly on the tie rod. When the telescopic column... When the column assembly rotates from a horizontal position to a vertical position, the gear teeth on the connecting column and the locking column mesh with each other, and the telescopic column assembly is limited by the spring tension, preventing it from rotating back. A push rod 508 that can be pushed axially is fixed on the locking column, and an elongated hole that mates with the push rod is provided on the column sleeve. The push rod passes through the elongated hole and can move axially inside the hole. When the telescopic column assembly needs to be unlocked to the vertical position and rotated back, simply push the push rod downward to disengage the gear teeth on the locking column from the gear teeth on the connecting column, and then rotate the telescopic column assembly back. The retaining ring and bolts are used to limit and fit the C-shaped tube sleeve onto the connecting column.

[0046] To prevent the telescopic column assemblies on the left and right sides from interfering with each other when in a horizontal position, height-increasing connectors 301 are fixedly installed at the upper ends of both ends of the left tie rod to increase the height of the left telescopic column assembly. The height-increasing connectors are L-shaped tubular structures. The left telescopic column assembly is rotatably connected to the height-increasing connectors through a rotation limiting assembly. In order to make the fixed positions of the four telescopic column assemblies form a rectangular distribution, the left tie rod with the height-increasing connectors is the same length as the right tie rod.

[0047] In order to ensure that the limiting block fits tightly with the telescopic column assembly, an arc-shaped recessed structure corresponding to the shape of the column sleeve is provided on the limiting block; when the telescopic column assembly rotates to the vertical position, the column sleeve fits perfectly with the arc-shaped recessed structure, thereby achieving vertical positioning of the telescopic column assembly.

[0048] In order to fix and remove the roof rack from the roof connector, fixing blocks 104 are fixedly installed on the left and right sides of the crossbeam and bolted to the roof connector. The bottom of the fixing block is provided with threaded holes that mate with the bolts. The bottom of the fixing block rests on the roof connector and is fixed by bolts, so as to fix the roof rack and the roof connector as a whole.

[0049] To increase the stability between the square frame and the tie rod, multiple horizontal plates 105 are fixedly arranged at intervals between the two vertical beams; telescopic horizontal plates 302 that interlock with the horizontal plates are fixedly installed on the inner side of the tie rod; the horizontal plates and the telescopic horizontal plates have a mutually cooperating concave-convex structure; an exit for people to pass through is provided at the sunroof position corresponding to the horizontal plate.

[0050] To create a shielding surface between the left and right telescopic column assemblies, a left and 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 are identical folding structures arranged symmetrically on the left and right sides. After folding, they can be placed inside the pull rod, and after unfolding, they can become the shielding surface between the telescopic column assemblies. The left and right abutments each include multiple spaced sliding shafts 801, folding shafts 802 positioned between the sliding shafts, multiple connecting plates 803 connecting the sliding shafts and the folding shafts, and bearings 805 at both ends of the sliding shafts; the folding surface includes sleeves 804 fixedly mounted on the sliding shafts or folding shafts at the upper and lower ends of the connecting plates; a slide rail supporting the up-and-down sliding of the left and right abutments is provided between the telescopic column assemblies; the slide rail has a segmented structure, consisting of an upper slide rail 601, a middle slide rail 408, and a lower slide rail 409 forming a complete slide rail; the upper slide rail is fixedly connected to a limiting block, and the middle slide rail is fixedly connected to the column sleeve (e.g., Figure 18 As shown, the lower slide rail is fixedly connected to the column jack; the bearings at the top of the left and right stops are fixedly installed inside the slide rail of the limiting block; the bearings on the left and right stops, except for the top bearing, slide vertically and are engaged with the inside of the slide rail. The column sleeve is also provided with a long opening to prevent interference between the column sleeve and the lower slide rail; when the telescopic column assembly falls vertically, the upper slide rail connects to the middle slide rail; when the column sleeve and the inner tube of the column are in a retracted state, the middle slide rail connects to the lower slide rail; when the column sleeve and the inner tube of the column are in an extended state, the middle slide rail separates from the lower slide rail, and the bearings need to be manually assisted to put the bearings that have slid out of the slide rail back into the corresponding slide rail during the up-and-down sliding process. A U-shaped component 106 is fixedly installed on the telescopic horizontal plate. A latch 21 for securing the left and right side panels in the folded state is fixedly installed on the U-shaped component and the telescopic horizontal plate. The folded left and right side panels are secured to the bottom of the telescopic horizontal plate by the latch 21 (e.g., ...). Figure 17 (As shown). The connecting plates in each row are arranged at uniform intervals, and the connecting plates in adjacent rows are arranged in an alternating pattern. This structural arrangement design ensures that the connecting plates of the left or right side panel will not interfere with each other after folding. This alternating arrangement design reduces the height of the left or right side panel after folding, thus saving the space temporarily used by the left or right side panel after folding.

[0051] To create a shielding surface between the two front telescopic pillar assemblies, a front shielding surface is provided between the front telescopic pillar assemblies; the front shielding surface is foldable and fixed to the inside of the crossbeam. The front shielding surface includes a square door frame 901 with its top hinged to the crossbeam, a door structure 902 located inside the square door frame, and folding baffles 903 hinged to both sides of the square door frame; a foot post 904 with height adjustment function is also fixedly installed at the bottom of the square door frame; an opening corresponding to the sunroof is provided on the door structure and the folding baffles. A triangular fixing plate 26 is fixedly installed on the front telescopic pillar assembly; a matching buckle 18 is provided on the folding baffle and the triangular fixing plate, which connects and fixes the folding baffle to the telescopic pillar assembly (e.g., ...). Figure 18 (As shown). A U-shaped component 107 is fixedly installed on the horizontal plate. A buckle 22 for securing the square door frame in its folded state is provided between the U-shaped component and the folding baffle. After folding, the square door frame can be fixed to the lower position of the horizontal plate via the buckle 22 (e.g., ...). Figure 17 (As shown).

[0052] To form a shielding surface between the two telescopic column assemblies on the rear side, a rear baffle is provided between the telescopic column assemblies on the rear side for shielding; the rear baffle can be folded and fixed to the inside of the crossbeam. The rear baffle includes a folding column 11 with its top hinged to the fixing block, a folding surface 12 disposed between the folding columns, and a detachable folding surface 13 disposed between the folding column and the telescopic column assembly; the structure of the folding surface and the detachable folding surface is the same as the structure of the left baffle and the right baffle, and the folding surface and the detachable folding surface respectively include multiple spaced sliding shafts, folding shafts disposed between the sliding shafts, multiple connecting plates connecting the sliding shafts and the folding shafts, and bearings fixedly disposed at both ends of the folding shafts; a foot post 121 with up-and-down adjustment function is fixedly disposed at the bottom of the folding column; a sleeve fitted on the sliding shaft or folding shaft is fixedly disposed at the upper and lower ends of the connecting plate, and the sleeve can rotate on the sliding shaft or folding shaft; a slide rail supporting the vertical sliding cooperation of the folding surface and the detachable folding surface is provided between the folding columns and between the folding column and the telescopic column assembly. The slide rail between the folding columns has a segmented structure, consisting of an upper slide rail 109 and a lower slide rail 122 forming a complete slide rail (e.g., Figure 15 (As shown). The upper slide rail is fixedly connected to the fixing block, and the lower slide rail is fixedly connected to the folding column. When the folding column falls vertically, the fixing block and the slide rail on the folding column are connected to form a complete slide rail. The bearing at the very top of the folding surface is fixed inside the slide rail on the fixing block, and the other bearings on the folding surface, except for the top bearing, are slidably fitted inside the slide rail. The threaded hole 19 at the bottom of the rear crossbeam fixing block is provided on the folding column (as shown). Figure 16As shown), the threaded hole is fixed to the roof connector by bolts. The connecting plates in each row are evenly spaced, and adjacent rows are staggered. This structural design prevents interference between the connecting plates when the folded or detachable folding surfaces are folded. This staggered arrangement reduces the height of the folded or detachable folding surfaces, saving space temporarily occupied after folding. A U-shaped component 111 is fixedly installed on the horizontal plate. A five-pronged buckle 25 is fixedly installed on the U-shaped component and the folded surface to secure the folded surface in the folded state. After folding, the folded surface can be fixed to the lower part of the horizontal plate by the five-pronged buckle (e.g., ...). Figure 17 (As shown).

[0053] The slide rail between the folding column and the telescopic column assembly has a segmented structure, consisting of an upper slide rail 601, a middle slide rail 408, and a lower slide rail 409 forming a complete slide rail. The upper slide rail is fixedly connected to a fixing block or a limiting block, the middle slide rail is fixedly connected to the folding column or column sleeve, and the lower slide rail is fixedly connected to the folding column or column-type jack. When the telescopic column assembly is lowered vertically, the lower slide rail on the telescopic column assembly connects to the middle slide rail. When the column sleeve and the inner tube of the column are retracted... 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 inner tube are in the extended state, the middle slide rail on the telescopic column assembly separates from the lower slide rail, forming a slide rail notch between them; a slide rail notch corresponding to the slide rail notch is provided between the middle and lower slide rails on the folding column; the bearing of the detachable folding surface can be inserted into the slide rail through this slide rail notch until the detachable folding surface is fully unfolded into the slide rail. The bearing at the very top of the detachable folding surface can be fixed to the slide rail by pin 23, achieving a limiting fixation between the top of the detachable folding surface and the slide rail (e.g., Figure 12 (As shown).

[0054] The folding baffle and the folding column are fixedly equipped with a four-element buckle 24 for fixing the folding column in the folded state. After the folding column is folded, it can be fixed to the position below the horizontal plate by the four-element buckle.

[0055] To prevent interference between the folding column and the rear tie rod, a tie rod sleeve 702 (e.g., ...) is provided on the rear tie rod, which can be fitted onto the folding column. Figure 14 (As shown).

[0056] To better facilitate the fixing and removal of the roof rack, the roof connector is equipped with a fixing seat 201 that connects to the fixing block and the limiting block. This fixing seat has holes corresponding to the threaded holes at the bottom of the fixing block for easy bolt connection. The limiting block and the fixing seat are equipped with matching latches 20, which prevent the retracted pull rod from extending outwards (e.g., ...). Figure 19(As shown); a recessed structure is provided on the inner side where the limiting block and the fixing block fit together to prevent interference between the fixing block and the limiting block.

[0057] In order to securely store the detachable tie rod on the roof rack, a fixing pin is fixedly installed at the front and rear positions of the top of the tie rod for placing and fixing the tie rod. The outer side of the fixing pin is threaded. After the connecting ring of the tie rod is inserted into the fixing pin from top to bottom, the tie rod is connected to the tie rod by screwing the nut 14 into the top of the fixing pin.

[0058] To ensure the telescopic pillar assembly is securely attached to the roof rack in a horizontal position, preventing swaying during vehicle travel, a fixing post 15 is fixedly installed at the top of the vertical beam to secure the left telescopic pillar assembly. This fixing post has a threaded hole at its top corresponding to the threaded through hole on the tie rod connector. The fixing post and tie rod connector can be connected and fixed with bolts, thus securing the left telescopic pillar assembly in its horizontally folded state. An arc-shaped recessed structure matching the right telescopic pillar assembly is provided on the crossbeam, allowing the horizontally folded right telescopic pillar assembly to fit snugly against this recessed structure. An extrusion block 17 is also provided on the right telescopic pillar assembly to fit snugly against the left telescopic pillar assembly. When the left telescopic pillar assembly is secured by the fixing post and fits snugly against the extrusion block, the right telescopic pillar assembly is clamped between the left telescopic pillar assembly and the arc-shaped recessed structure on the crossbeam, thus securing the right telescopic pillar assembly in its horizontally folded state (e.g., ...). Figure 19 (As shown).

[0059] The left, right, front, and rear roof racks, once folded and secured, do not interfere with each other. After folding, they can be placed in the bottom space of the square frame, and the height of the folded roof rack will not exceed national regulations. The folded left and right roof racks can be placed in the inner space between the crossbeams; the folded front and rear roof racks can be placed in the space at the bottom of the crossbeams. The detachable folding panels cannot be placed in the bottom space of the square frame and require additional storage space.
