Description

Technical Field

[0001] The utility model relates to an automobile accessory, in particular to a simple automobile roof luggage rack. Background Art

[0002] With the increasing number of cars on the road, more and more car owners are looking to increase their car's carrying capacity by installing roof racks. This is especially true when traveling long distances or engaging in outdoor activities. Roof racks provide additional storage space and can effectively reduce the pressure of carrying items inside the car. Therefore, roof racks have become a common accessory on cars.

[0003] Most roof racks currently in widespread use are one-piece structures. These typically incorporate multiple components, including crossbeams, vertical beams, and a base, that are fixed together and then installed on the vehicle's roof at once. While this design offers a certain level of strength and stability, it also suffers from significant drawbacks and deficiencies in practical use, primarily in the following areas:

[0004] 1. Large packaging volume: Because the one-piece structure cannot be disassembled or folded, it must maintain its intact shape during production and transportation. This results in bulky packaging and inefficient transportation. Especially in online sales, shipping volume directly impacts logistics costs. The inability to disassemble an integrated roof rack results in a larger unit, resulting in high shipping costs, increasing the final sales price and weakening the product's market competitiveness.

[0005] 2. High material costs: Integrated luggage racks typically require a significant amount of material to ensure overall strength and rigidity. While this design improves the rack's strength, it also leads to material waste and increased production costs. Furthermore, due to their complex structure, the manufacturing process for integrated luggage racks requires more sophisticated craftsmanship, further increasing production costs.

[0006] 3. High storage costs: Integrated roof racks, due to their non-detachable nature, take up a significant amount of storage space during sales and storage. This not only increases storage costs but also limits inventory management flexibility. This is especially true when large quantities need to be stored, as warehouse space utilization decreases significantly, further increasing operating costs.

[0007] 4. Disadvantages existing online sales models: With the rapid development of e-commerce, more and more car owners are purchasing auto parts and accessories online. Due to their large size and weight, integrated roof racks are not suitable for shipping via conventional logistics methods such as express delivery. This not only increases logistics and distribution challenges but also raises the purchase threshold for consumers. Many consumers face high shipping costs or long delivery times during the purchase process, which degrades their shopping experience.

[0008] Therefore, although the integrated roof rack in the prior art has a certain market share, its shortcomings in packaging, transportation, warehousing and online sales are obvious, and a new roof rack structure is urgently needed to overcome these shortcomings. Utility Model Content

[0009] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a simple car roof luggage rack with a simple structure, easy to use, modular design of the product, easy to disassemble and install, and at the same time greatly reducing the packaging volume, thereby reducing material, storage and logistics costs, and adapting to the sales needs of the modern e-commerce environment.

[0010] The purpose of the utility model is achieved in the following way: a simple car roof luggage rack, which includes a first crossbeam and a second crossbeam, the first crossbeam and the second crossbeam are arranged in parallel, and a plurality of vertical beams are installed between the two crossbeams;

[0011] The first and second cross beams are provided with a plurality of mounting slots extending through their bodies, and mounting holes are provided on both end surfaces of the vertical beams. Fixing bolts pass through the mounting slots on the cross beams and are screwed into the mounting holes to fix the vertical beams between the first and second cross beams.

[0012] The first crossbeam and the second crossbeam are further provided with a first hinge hole, and the base is provided with a second hinge hole, and the hinge bolt passes through the first hinge hole and is hinged to the second hinge hole;

[0013] The base is provided with a plurality of fixing holes, and the mounting bolts pass through the fixing holes to connect with the vehicle body.

[0014] Furthermore: the first crossbeam and the second crossbeam are plate-shaped structures, and the vertical beams are butt-jointed and installed on the sides of the first crossbeam and the second crossbeam.

[0015] Furthermore, wind guide beams are obliquely installed at the front ends of the first crossbeam and the second crossbeam, and the wind guide beams are arranged with the front being low and the back being high.

[0016] Furthermore: the vertical beams and wind guide beams are both made of aluminum profiles.

[0017] Furthermore: the installation groove is a long waist-shaped through groove, and a plurality of installation grooves are evenly distributed on the first beam and the second beam.

[0018] Furthermore: there are two bases, distributed on the first beam and the second beam.

[0019] The beneficial effects of the utility model are: 1. Simple structure, low production cost and improved market competitiveness.

[0020] 2. The roof rack of this utility model comprises multiple modular components, including a first crossbeam, a second crossbeam, a vertical beam, and a base. These components are secured together using bolts and hinged holes. When needed, the components can be easily assembled and installed; when not in use, they can be quickly disassembled and stored. This design greatly simplifies the installation and removal process of the roof rack and enhances the user experience.

[0021] 3. Compared to traditional one-piece roof racks, this new model's modular design allows it to be disassembled into multiple sections during transportation and storage. Through proper disassembly, the rack's overall volume is significantly reduced, making packaging more compact and easier to transport. This not only reduces logistics costs, particularly in e-commerce scenarios, but also reduces the risk of damage to large racks during transportation, further enhancing ease of sale and use.

[0022] 4. Through a rational modular design, the roof rack of this utility model can reduce the overall material usage and reduce manufacturing costs through standardized production processes. Since the complex one-piece molding process is no longer required, the manufacturing process is simplified, further improving production efficiency and reducing costs.

[0023] 5. The design of this utility model is not only simpler and lighter in structure, but also can be adjusted according to different vehicle models and user needs. By adjusting the number and size of horizontal and vertical beams, it can be adapted to a variety of vehicle roof specifications, making it more adaptable.

[0024] 6. This new design optimizes the aerodynamic performance of the roof rack by installing an oblique wind deflector at the front end of the crossbeam, with the wind deflector arranged low in the front and high in the back. This reduces wind resistance and noise at high speeds, improving both driving stability and fuel efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention is further described below in conjunction with the accompanying drawings. A simple car roof rack comprises a first crossbeam 1 and a second crossbeam 2, the first crossbeam 1 and the second crossbeam 2 being arranged in parallel, with a plurality of vertical beams 3 installed between the two crossbeams;

[0030] The first crossbeam 1 and the second crossbeam 2 are provided with a plurality of mounting slots 4 extending through their bodies, and mounting holes 6 are provided on both end surfaces of the vertical beam 3. Fixing bolts 7 pass through the mounting slots 4 on the crossbeams and are screwed into the mounting holes 6 to fix the vertical beam 3 between the first crossbeam 1 and the second crossbeam 2.

[0031] The first crossbeam 1 and the second crossbeam 2 are further provided with a first hinge hole 8, and the base 9 is provided with a second hinge hole 10, and a hinge bolt 11 passes through the first hinge hole 8 and is hinged to the second hinge hole 10;

[0032] The base 9 is provided with a plurality of fixing holes 12 , through which mounting bolts pass to connect with the vehicle body.

[0033] In one embodiment, the first crossbeam 1 and the second crossbeam 2 are plate-shaped structures, and the vertical beams 3 are butt-jointedly installed on the sides of the first crossbeam 1 and the second crossbeam 2 .

[0034] In one embodiment, wind guide beams 13 are obliquely installed at the front ends of the first crossbeam 1 and the second crossbeam 2 , and the wind guide beams 13 are arranged with the front being lower and the back being higher.

[0035] In one embodiment, the vertical beams 3 and the wind guide beams 13 are both made of aluminum profiles.

[0036] In one embodiment, the mounting groove 4 is a long waist-shaped through groove, and a plurality of mounting grooves 4 are evenly distributed on the first crossbeam 1 and the second crossbeam 2 .

[0037] In one embodiment, two bases 9 are provided, distributed on the first crossbeam 1 and the second crossbeam 2 .

[0038] Working Principle: In this case, a first crossbeam 1 and a second crossbeam 2 are arranged parallel to each other on the left and right sides of the roof, supported by a number of vertical beams 3. Mounting holes 6 are provided at each end of the vertical beams 3. Fixing bolts 7 pass through mounting slots 4 on the crossbeams and are screwed into these mounting holes 6, firmly securing the vertical beams 3 between the first and second crossbeams 1 and 2. This screw connection ensures the stability of the entire luggage rack structure while facilitating assembly and disassembly.

[0039] Through this modular screw-connected structure, the luggage rack is not only easy to disassemble and install, greatly improving the user's operating convenience; but also, when it is not needed, the user can easily disassemble and store it, reducing unnecessary space occupation.

[0040] Furthermore, at the connection between the crossbeams and the base, first hinge holes 8 are defined on the first and second crossbeams 1 and 2, while second hinge holes 10 are defined on the base 9. Hinge bolts 11 pass through the first and second hinge holes 8 and 10, creating a hinged connection between the base 9 and the crossbeams. Several fixing holes 12 on the base allow bolts to secure the base 9 to the vehicle body, ensuring the luggage rack is securely attached to the roof.

[0041] The hinged design makes the rack more flexible during installation, making it easier to adjust the angle and position to suit the roof curvature of different vehicles, enhancing the rack's installation adaptability. The combination of screw and hinged structure also significantly improves the rack's structural strength and stability.

[0042] In addition, wind guide beams 13 are installed diagonally at the front ends of the first and second crossbeams 1 and 2, with the beams arranged low in the front and high in the back. This design allows air to pass smoothly over the roof rack, preventing air from directly hitting the rack during high-speed driving, thereby reducing air resistance and noise during driving.

[0043] The wind deflector design significantly optimizes the roof rack's aerodynamic performance, effectively reducing wind resistance and noise, especially at high speeds. This not only improves vehicle stability but also reduces fuel consumption. Furthermore, the wind deflector, like the vertical and horizontal beams, is constructed from lightweight yet durable aluminum, ensuring the strength and durability of the entire roof rack.

[0044] Several mounting slots 4 are formed throughout the first and second crossbeams 1 and 2. These slots are long, waist-shaped and evenly distributed throughout the crossbeams. Vertical beams 3 can be freely adjusted within the slots using bolts, enabling different mounting distances and angles to accommodate various roof and vehicle body shapes.

[0045] The long, waist-shaped mounting slot design greatly enhances installation flexibility. Users can adjust the vertical beam position based on vehicle roof size and actual needs, making the rack adaptable to different types of vehicles. This design not only improves the rack's applicability but also facilitates personalized installation needs.

[0046] There are two bases 9, one on the first crossbeam 1 and the other on the second crossbeam 2, which are fixed to the vehicle body by fixing bolts. This two-point fixing design ensures the stability of the luggage rack during driving and avoids the loosening or shaking that may be caused by a single-point support.

[0047] The point-fixing method makes the load distribution of the luggage rack more uniform, effectively distributing the load and enhancing the load-bearing capacity of the luggage rack. At the same time, during the installation process, the double-base structure can more firmly fix the luggage rack to the roof, ensuring the safety of the vehicle when driving at high speed.

[0048] In summary, the simplified car roof rack of this utility model utilizes a modular design, allowing for flexible assembly and disassembly of its components via bolts and hinges, simplifying installation and disassembly. Furthermore, this utility model not only addresses the numerous shortcomings of existing integrated roof racks in packaging, transportation, storage, and installation, but also adapts to the logistics requirements of an e-commerce environment, offering significant technical advantages and market competitiveness.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
