Description

Technical Field

[0001] This application belongs to the field of automotive technology, specifically relating to a space-variable roof platform luggage rack, the vehicle thereof, and its usage method. Background Technology

[0002] Currently, the most common types of roof racks on the market include split longitudinal rails, flush longitudinal rails, and full-frame types. Split longitudinal rails have a gap in the middle, allowing items to be secured directly with ropes, and are relatively inexpensive; flush longitudinal rails have a simple appearance and are mostly used in high-end models, but require the addition of a transverse roof rack; full-frame types have strong load-bearing capacity and can carry heavy objects without additional crossbars.

[0003] However, existing roof racks still have several problems. First, most roof racks require additional crossbeams to load heavy items, and these crossbeams are fixed in position and cannot be flexibly adjusted according to the size of the luggage, thus limiting loading space. Second, if the vehicle has a sunroof, the crossbeams can easily obstruct the rear passenger's view, affecting the sunroof opening experience. Additionally, adding a roof rack increases wind resistance, resulting in noticeable wind noise at high speeds, and also increases fuel consumption—fuel consumption can increase by 5%-8% for every 10km / h increase in speed. Based on these pain points, it is necessary to optimize the roof rack structure. Summary of the Invention

[0004] The purpose of this application is to provide a space-variable roof platform luggage rack, the same vehicle, and a method of using it, in order to solve the technical problems of the prior art where the crossbeam position is fixed, the loading space is limited, and the opening of the sunroof is affected.

[0005] To achieve the above objectives, this application adopts the following technical solution: In a first aspect, this application discloses a space-variable roof platform luggage rack, comprising: The load-bearing frame is installed on the roof of the vehicle body; The right platform frame mounting beam and the left platform frame mounting beam are fixed to the load-bearing frame. The load-bearing crossbeam is fixed at both ends to the right platform frame mounting beam and the left platform frame mounting beam, respectively, according to the usage requirements, and / or the load-bearing crossbeam is fixed at both ends to the right platform frame mounting beam and the left platform frame mounting beam by crossbeam mounting blocks.

[0006] Preferably, the load-bearing frame includes a left frame longitudinal beam and a right frame longitudinal beam, which are detachably mounted on the vehicle roof. The vehicle's travel direction is parallel to the left and right frame longitudinal beams. The left platform frame mounting beam is detachably mounted on the left frame longitudinal beam, and the right platform frame mounting beam is detachably mounted on the right frame longitudinal beam.

[0007] Preferably, the vehicle roof is detachably connected to a cast aluminum base, and an outer aluminum support is detachably connected to the cast aluminum base. Both the left and right frame longitudinal beams are detachably connected to the outer aluminum support, and a sealing gasket is provided between the cast aluminum base and the vehicle roof.

[0008] Preferably, the left frame longitudinal beam and the right frame longitudinal beam are respectively provided with a left front position light cover and a right front position light cover at the end near the front of the vehicle, and respectively provided with a left rear position light cover and a right rear position light cover at the end near the rear of the vehicle.

[0009] Preferably, a windshield assembly is detachably mounted on one end of the support frame, and a tail wing decorative cover is mounted on the other end.

[0010] Preferably, when the luggage rack is not in use, the two ends of the cargo beam are fixed to the right platform frame mounting beam and the left platform frame mounting beam, respectively, on the side near the rear of the vehicle.

[0011] Preferably, when using the luggage rack, the two ends of the cargo beam are detachably fixed to the right platform frame mounting beam and the left platform frame mounting beam via beam mounting blocks, and are evenly or partially arranged above the vehicle roof. Preferably, when both ends of the load-bearing crossbeam are fixed to the right platform frame mounting beam and the left platform frame mounting beam via crossbeam mounting blocks, the load-bearing crossbeam is raised by 23~26 mm.

[0012] Preferably, the crossbeam mounting block is detachably mounted on the right platform frame mounting beam and the left platform frame mounting beam, and the right platform frame mounting beam and the left platform frame mounting beam are provided with a number of reserved mounting points for mounting the crossbeam mounting block.

[0013] Secondly, this application discloses an automobile including a roof rack with variable space as described in any of the above claims.

[0014] Thirdly, this application discloses a method for using the variable-space roof rack as described in any one of the above claims, including: When the luggage rack is not in use, fix both ends of the cargo beam to the right platform frame mounting beam and the left platform frame mounting beam, respectively, on the side near the rear of the vehicle. When using the luggage rack, the two ends of the load-bearing crossbeam can be detachably fixed to the right platform frame mounting beam and the left platform frame mounting beam via crossbeam mounting blocks.

[0015] Compared with the prior art, this application has the following beneficial effects: This application discloses a variable-space roof rack, which features relatively fixed right and left platform frame mounting beams, upon which a cargo crossbeam is mounted. The position and installation method of the cargo crossbeam can be adjusted according to actual loading needs, achieving versatility in loading space. Compared to the limitations of traditional roof racks with fixed crossbeam positions and the need for additional crossbeams when loading heavy items, this solution can flexibly adapt to the fixing needs of items of different sizes, such as suitcases, bicycles, and camping equipment, significantly improving the utilization rate of roof space. Because the position of the cargo crossbeam is adjustable, users can install the crossbeam in a position that does not obstruct the sunroof's view or opening space, based on the sunroof's opening trajectory. This effectively avoids the problems of traditional roof racks where fixed crossbeam positions obstruct the rear passenger view and affect the normal opening of the sunroof, ensuring sufficient movement space between the sunroof opening and the cargo on the roof rack, improving driving comfort and customer experience. Furthermore, the roof rack has a stable structure and can serve as a mounting base for accessories such as roof tents, suitcases, or lights, expanding the vehicle's functionality in scenarios such as road trips and camping.

[0016] Furthermore, by installing marker light covers and decorative covers at the front and rear ends of the left and right frame longitudinal beams respectively, an installation base for the integrated marker lights is provided. When driving at night or in low visibility conditions, the marker lights can clearly indicate the outline of the roof rack and the width of the vehicle, effectively reminding vehicles behind and on the opposite side to pay attention and avoid them, reducing the safety hazards caused by the roof rack obstructing the original vehicle lights, and significantly improving driving safety.

[0017] Furthermore, by detachably mounting a wind deflector assembly at the front of the load-bearing frame, the airflow over the roof rack can be effectively streamlined during high-speed driving, reducing the generation of air turbulence, significantly lowering the drag coefficient and driving noise, thereby improving cabin quietness and reducing fuel consumption. The detachable structure allows users to flexibly install or remove it according to actual usage needs, taking into account aerodynamic performance in different scenarios such as daily commuting and cargo transportation.

[0018] Furthermore, a rear spoiler cover is installed at the rear of the load-bearing frame. On the one hand, it continues the deflection effect of the windshield assembly and reduces the resistance and noise caused by the separation of airflow at the rear. On the other hand, the rear spoiler cover visually finishes the end of the roof rack, making the overall shape more streamlined and harmonious, improving the aesthetics of the vehicle's rear visibility, and satisfying users' dual pursuit of off-road style and exquisite appearance.

[0019] Furthermore, when the roof rack is not in use, the two ends of the cargo beam are fixed to the right platform frame mounting beam and the left platform frame mounting beam, respectively, near the rear of the vehicle. When the sunroof is open, the cargo beam of the roof rack will not obstruct the view, improving the user's travel experience. In addition, lowering the crossbar can also reduce wind resistance and reduce fuel consumption.

[0020] Furthermore, the two ends of the cargo beam are fixed to the right platform frame mounting beam and the left platform frame mounting beam by the beam mounting blocks. The cargo beam is raised by 23~26 mm to ensure that the sunroof can be opened smoothly when the platform luggage rack is in use, and to ensure that the sunroof can operate safely.

[0021] Furthermore, several reserved installation points are set for installing the crossbeam mounting blocks, and the installation position can be adjusted as needed to achieve flexible and versatile loading space. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] The roof rack proposed in this application solves the problem of traditional roof racks requiring additional crossbeams for loading heavy items. Furthermore, the roof-mounted crossbeam 11 can be moved according to requirements, allowing for flexible loading space. It also prevents the crossbeam 11 from obstructing the view when the sunroof is open, thus ensuring a good customer experience. Simultaneously, it provides sufficient space for movement between the sunroof and the roof rack crossbeam 11. See details... Figure 1 This application discloses a space-variable rooftop luggage rack, comprising: The load-bearing frame is installed on the roof of the vehicle body; The right platform frame mounting beam 8 and the left platform frame mounting beam 10 are fixed to the load-bearing frame. The cargo beam 11, according to usage requirements, is fixed at both ends to the right platform frame mounting beam 8 and the left platform frame mounting beam 10, and / or, at both ends, is fixed to the right platform frame mounting beam 8 and the left platform frame mounting beam 10 via beam mounting blocks 9. By setting relatively fixed right platform frame mounting beam 8 and left platform frame mounting beam 10, and installing the cargo beam 11 on them, and the position and installation method of the cargo beam 11 can be adjusted according to actual loading needs, a versatile loading space is achieved. Compared to the limitations of traditional luggage racks with fixed beam positions and the need for additional beams when loading heavy items, this solution can flexibly adapt to the fixing needs of items of different sizes such as suitcases, bicycles, and camping equipment. It can accommodate large items (such as suitcases, bicycles, and camping equipment) without occupying interior space, thus increasing loading capacity. It significantly improves the utilization rate of roof space. The cargo beam 11 is easy to remove and place, adapts to various vehicle models, and can be installed or removed at any time as needed. Because the position of the cargo beam 11 is adjustable, users can install it in a position that does not obstruct the sunroof's view or opening space, according to the sunroof's opening trajectory. The beautifully designed roof rack enhances the vehicle's visual appeal, adding personalization and off-road style. It can serve as a mounting base for roof tents, luggage boxes, or lights, making it suitable for road trips, camping, and other similar scenarios. The front wind deflector reduces wind noise.

[0027] In some embodiments, the load-bearing frame includes a left frame longitudinal beam 3 and a right frame longitudinal beam 7, which are detachably mounted on the vehicle roof. The vehicle's direction of travel is parallel to the left and right frame longitudinal beams 3 and 7. A left platform frame mounting beam 10 is detachably mounted on the left frame longitudinal beam 3, and a right platform frame mounting beam 8 is detachably mounted on the right frame longitudinal beam 7. The left and right frame longitudinal beams 3 and 7 are detachable from the vehicle body, allowing users to install or remove the roof rack as needed. When not carrying cargo, the roof rack can be removed to reduce wind resistance and fuel consumption. Furthermore, the parallel orientation of the left and right frame longitudinal beams 3 and 7 to the direction of travel helps airflow along the vehicle body, reducing additional wind noise and drag. Additionally, this modular structure makes maintenance and replacement more convenient, allowing for partial replacement without the need for complete scrapping. Overall, this design balances strength, flexibility, and aerodynamic performance, significantly improving practicality.

[0028] In some embodiments, such as Figure 2 , Figure 3 As shown, the left frame longitudinal beam 3 and the right frame longitudinal beam 7 are connected by bolts and nuts (as shown). Figure 4 Connected to the roof of the vehicle body, the left platform frame mounting beam 10 is detachably mounted on the left frame longitudinal beam 3; the right platform frame mounting beam 8 is detachably mounted on the right frame longitudinal beam 7, see [link / reference]. Figure 5 .

[0029] In some embodiments, see Figure 4 The roof cover is detachably connected to a cast aluminum base 13, and an outer aluminum support 15 is detachably connected to the cast aluminum base 13. Both the left frame longitudinal beam 3 and the right frame longitudinal beam 7 are detachably connected to the outer aluminum support 15. A sealing gasket is provided between the cast aluminum base 13 and the roof cover. Firstly, the connection strength is guaranteed. The cast aluminum base 13 itself has high strength and good corrosion resistance, which can distribute the load borne by the roof rack to the vehicle body, avoiding localized stress concentration that could lead to deformation of the body sheet metal. Secondly, waterproof sealing is effective. The sealing gasket, under the pre-tightening force of the bolts, fills the gaps in the contact surface, effectively preventing rainwater from seeping into the vehicle through the mounting holes and protecting the internal structure of the vehicle body from rust. Thirdly, it is detachable and easy to maintain. The cast aluminum base 13 and the outer aluminum support 15, as well as the outer aluminum support 15 and the longitudinal beams, are all detachably connected. This means that users can replace worn supports or upgrade the roof rack style as needed without altering the original drilling positions. Fourth, the materials are reasonably matched. The cast aluminum parts serve as the base to ensure structural rigidity, while the aluminum supports and longitudinal beams take into account the need for lightweighting. Overall, it is both sturdy and does not add too much burden to the roof.

[0030] In some embodiments, the left frame longitudinal beam 3 and the right frame longitudinal beam 7 are respectively provided with a left front position light cover 2 and a right front position light cover 12 near the front of the vehicle, and respectively provided with a left rear position light decorative cover 4 and a right rear position light decorative cover 6 near the rear of the vehicle. By providing position light covers and decorative covers at the front and rear ends of the left and right frame longitudinal beams, an installation base is provided for the integrated position lights. When driving at night or in low visibility conditions, the position lights can clearly indicate the outline of the roof rack and the width of the vehicle, effectively reminding rear and oncoming vehicles to pay attention and avoid them, reducing the safety hazards caused by the roof rack obstructing the original vehicle lights, and significantly improving driving safety. The position light covers and decorative covers not only serve to fix and accommodate the lights, but also provide effective protection for the lights, preventing damage to the lights from mud, sand, flying stones, etc. Their design can serve as an extension element of the vehicle's appearance, making the front and rear connections of the roof rack more natural and smooth, enhancing the overall sense of unity and refinement of the vehicle, and meeting users' aesthetic needs for vehicle personalization and off-road style.

[0031] In some embodiments, a wind deflector assembly 1 is detachably mounted on one end of the support frame. By detachably mounting the wind deflector assembly at the front end of the support frame, the airflow over the roof rack can be effectively streamlined during high-speed driving, reducing the generation of air turbulence, significantly reducing the drag coefficient and driving wind noise, thereby improving the quietness of the vehicle interior and reducing fuel consumption. The detachable structure allows users to flexibly install or remove the wind deflector assembly according to actual usage needs, taking into account the aerodynamic performance in different scenarios such as daily commuting and cargo transportation. A rear spoiler cover 5 is mounted on the other end. On the one hand, it continues the deflector assembly's aerodynamic effect, reducing the drag and noise caused by rear airflow separation; on the other hand, the rear spoiler cover visually finishes the end of the roof rack, making the overall shape more streamlined and harmonious, improving the aesthetics of the vehicle's rear visibility, and satisfying users' dual pursuit of off-road style and refined appearance.

[0032] In some embodiments, when the luggage rack is not in use, see Figure 7 The cargo beam 11 is fixed at both ends to the right platform frame mounting beam 8 and the left platform frame mounting beam 10, respectively, near the rear of the vehicle. When the sunroof is open, the cargo beam of the roof rack will not obstruct the view, improving the user's travel experience. In addition, lowering the crossbar can reduce wind resistance and reduce fuel consumption.

[0033] In some embodiments, when the luggage rack is used, the two ends of the cargo beam 11 are detachably fixed to the right platform frame mounting beam 8 and the left platform frame mounting beam 10 via the beam mounting blocks 9, and are evenly or partially arranged above the vehicle roof. Preferably, when the two ends of the cargo beam 11 are fixed to the right platform frame mounting beam 8 and the left platform frame mounting beam 10 via the beam mounting blocks 9, the cargo beam 11 is raised by 23-26 mm. This ensures that the sunroof can be opened smoothly and that the sunroof can operate safely when the platform luggage rack is in use.

[0034] In some embodiments, the crossbeam mounting block 9 is detachably mounted on the right platform frame mounting beam 8 and the left platform frame mounting beam 10, and the right platform frame mounting beam 8 and the left platform frame mounting beam 10 have several reserved mounting points 17 for mounting the crossbeam mounting block 9. The mounting position can be adjusted as needed, breaking the limitations of traditional fixed luggage rack positions and achieving flexible and versatile cargo space. Furthermore, the fixation is more secure because each reserved mounting point is an independent mechanical connection. Compared to the sliding groove structure that relies entirely on friction for fixation, it is more stable when bearing heavy loads and less prone to displacement. It also has strong adaptability; users can precisely adjust the crossbeam position according to the fixing dimensions of different accessories such as bicycle brackets and luggage rack buckles, eliminating the need for makeshift binding with ropes as before. In addition, the design of multiple reserved points avoids the sunroof location, solving the old problems of the crossbeam obstructing the rear passenger view and affecting sunroof opening.

[0035] Example A space-variable roof platform luggage rack includes four cast aluminum mounting brackets on each side, two platform frame mounting beams on the left and right, and a full-frame luggage rack assembly (front windshield assembly 1, rear spoiler cover 5, aluminum alloy frame longitudinal beams on both sides, side marker light mounting covers on both sides, and cargo crossbeam 11 in the middle). like Figure 1 As shown in the exploded view, the platform luggage rack includes a wind deflector assembly 1, a left front position light cover 2, a left frame longitudinal beam 3, a left rear position light decorative cover 4, a tail wing decorative cover 5, a right rear position light decorative cover 6, a right frame longitudinal beam 7, a right platform frame mounting beam 8, a crossbeam mounting block 9, a left platform frame mounting beam 10, and a cargo crossbeam 11.

[0036] like Figure 2 As shown, the left frame longitudinal beam 3 and the right frame longitudinal beam 7 are connected by bolts and nuts (as shown). Figure 4 The left platform frame mounting beam 10 and the right platform frame mounting beam 8 are connected to the roof of the vehicle body and are mounted on the left and right load-bearing longitudinal beams; the cargo-carrying crossbeam 11 can be installed on the left platform frame mounting beam 10 and the right platform frame mounting beam 8 as needed (e.g., Figure 7 ), or installed on the crossbeam mounting block 9 (such as Figure 6The wind deflector assembly 1 and the rear spoiler cover 5 are bolted to the left frame longitudinal beam 3 and the right frame longitudinal beam 7. Through modular connections, the left frame longitudinal beam 3 and the right frame longitudinal beam 7, the left platform frame mounting beam 10 and the right platform frame mounting beam 8, the cargo crossbeam 11, and the aerodynamic kit are combined into a single unit. The left frame longitudinal beam 3 and the right frame longitudinal beam 7 serve as basic support components, rigidly connected to the vehicle roof with bolts and nuts to ensure load-bearing capacity. The left platform frame mounting beam 10 and the right platform frame mounting beam 8 are mounted on the longitudinal beams, forming a load-bearing platform. The cargo crossbeam 11 offers two installation methods—it can be directly fixed to the platform frame mounting beam 10 and the right platform frame mounting beam 8, or connected via the crossbeam mounting block 9, to adapt to different loading requirements. The wind deflector assembly 1 and the rear spoiler cover 5 are bolted to the frame longitudinal beams, serving to regulate airflow. This layered assembly and multi-point adjustable design ensures both structural strength and operational flexibility.

[0037] like Figure 3 As shown in the diagram, this is a schematic diagram of the connection between the left and right longitudinal beams and the vehicle body. The roof is connected to the cast aluminum base 13 by bolts. The cast aluminum base 13 is connected to the outer aluminum support 15 (the mounting beams of the left and right platform frames) by two hexagonal nuts. The outer aluminum support 15 is connected to the left frame longitudinal beam 3 and the right frame longitudinal beam 7 by nuts. EPDM foam sealing material is pasted on the bottom of the cast aluminum base 13 for sealing. First, the structure is stable and reliable. The cast aluminum base has high strength and rigidity, which can evenly transfer the load borne by the roof rack and the vibration load during driving to the vehicle body, avoiding local stress concentration that could lead to deformation or cracking of the roof sheet metal. Second, the waterproof sealing is in place. The EPDM foam sealing material has excellent weather resistance, aging resistance and compression resilience. It can maintain elasticity under the long-term pre-tightening force of the bolts, effectively preventing rainwater, car wash water and even water from seeping into the mounting holes during high-pressure water washing, protecting the internal structure of the vehicle body from rust and leakage. Third, maintenance is convenient. All connection points are detachable. If the outer aluminum bracket or frame longitudinal beam is damaged, it can be replaced simply by loosening the corresponding nuts, without needing to disassemble the cast aluminum base fixed to the vehicle body, greatly reducing maintenance difficulty and cost. Fourth, the materials are reasonably matched. The cast aluminum base ensures the structural strength of the connection points, while the outer aluminum bracket and frame longitudinal beam are made of aluminum alloy to reduce weight, making them sturdy without adding too much burden to the roof, which is in line with the trend of lightweight design.

[0038] Figure 5The roof rack frame is connected to the mounting longitudinal beams using semi-hexagonal rivet nuts. The mounting longitudinal beams of the roof rack are typically made of aluminum alloy profiles with thin walls and large internal cavities, making it impossible to directly machine threaded holes of sufficient depth. The semi-hexagonal rivet nuts create high-strength threaded connections in the thin walls through deformation and expansion. Installation and maintenance are more convenient; all operations are completed from the outside, without disassembling the longitudinal beams or entering the roof interior. Users or maintenance personnel can easily install and remove the roof rack frame. The connection is more reliable and secure; the semi-hexagonal structure effectively prevents the nut from rotating, ensuring it won't loosen even after long-term use or vibration, guaranteeing the safety of the roof rack. The appearance is clean; the tail of the rivet nut is flat after installation, not protruding and affecting the surface of the longitudinal beams, and avoiding exposed bolt heads that affect aesthetics. When we need to load luggage, such as... Figure 6 The cargo beam 11 is installed on the beam mounting block 9. The beam mounting block 9 is bolted to the aluminum alloy frame of the platform luggage rack. Then, the cargo beam 11 is bolted to the beam mounting block 9. The cargo beam 11 can be raised 25mm to ensure that the sunroof can be opened smoothly when the platform luggage rack is in use, and to ensure the safe operation of the sunroof. Figure 6 When we are not using the luggage rack to load heavy items, the load-bearing crossbeam 11 can be directly mounted on the frame longitudinal beam (e.g., Figure 7 This allows the crossbars to be installed at the rear of the frame's longitudinal beams. When the sunroof is open, the platform luggage rack crossbars will not obstruct the view, providing a better travel experience. Lowering the crossbars also reduces wind resistance and fuel consumption. In addition, such as... Figure 8 As shown, the crossbeam mounting block 9 can be moved as needed, and all the pre-set mounting points can be used to create various loading methods, achieving a flexible and versatile cargo space. Furthermore, the variable loading configuration of this roof rack enhances the overall appearance of the vehicle, improving its aesthetics compared to ordinary roof racks. This variable-space roof rack can hold large items (such as suitcases, bicycles, and camping equipment) without taking up interior space, increasing loading capacity. It is easy to access, compatible with various vehicle models, and can be installed or removed as needed. A beautifully designed roof rack enhances the vehicle's visual appeal, adding personalization and off-road style. It can serve as a mounting base for roof tents, suitcases, or lights, suitable for road trips, camping, and other scenarios. The front wind deflector reduces wind noise.

[0039] This application also discloses a vehicle including a roof rack with variable space as described in any of the above claims.

[0040] This application also discloses a method of using a space-variable roof rack as described in any of the above claims, including: When the roof rack is not in use, fix both ends of the cargo beam 11 to the right platform frame mounting beam 8 and the left platform frame mounting beam 10 respectively, close to the rear of the vehicle; the cargo beam 11 will lie against the rear of the roof rack, without taking up the front space of the roof, and without interfering with the opening of the sunroof or the view.

[0041] When using the luggage rack, the two ends of the load-bearing crossbeam 11 are detachably fixed to the right platform frame mounting beam 8 and the left platform frame mounting beam 10 via crossbeam mounting blocks 9. By moving the position of the crossbeam mounting blocks 9 on the mounting beams, the front and rear positions of the crossbeam can be freely adjusted to accommodate the loading needs of luggage of different sizes. Loading flexibility is greatly improved. By adjusting the position of the crossbeam through the mounting blocks, a suitable fixing point can be found whether placing suitcases or tying bicycles, truly achieving "variable space". Furthermore, it is very convenient to operate, requiring no special tools, and ordinary users can complete the switching between modes in a few minutes.
