[0043] In related technologies, due to vehicle height restrictions and the need to ensure adequate passenger space, a single-layer roof structure is generally used. However, due to the limited number of connection points and force transmission paths between the single-layer roof structure and the vehicle's internal frame, the rigidity is poor. Furthermore, the single-layer roof structure cannot effectively isolate the passenger compartment from the vehicle's rear cabin, resulting in poor safety and NVH performance. To address these issues, the present invention provides a roof structure with a double-layer roof structure that increases the connection and force transmission paths between the roof structure and the vehicle's internal frame, effectively improving the rigidity of the vehicle body.
[0044] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0045] Figure 1 Schematic diagram of the installation structure of the roof structure on the vehicle body shown in an embodiment of the present application; Figure 2 It is an exploded view of the top cover structure shown in the embodiment of the present application.
[0046] See also Figure 1 and Figure 2 The present application provides a roof structure 100, which includes a lower roof cover 110 and an upper roof cover 120; the lower roof cover 110 and the upper roof cover 120 are arranged at intervals in the height direction Z of the vehicle; the lower roof cover 110 includes a lower cross beam assembly and a lower roof cover plate 113 covering the lower cross beam assembly, and the upper roof cover 120 includes an upper cross beam assembly and an upper roof cover plate 122 covering the upper cross beam assembly; wherein the lower cross beam assembly and the upper cross beam assembly are respectively connected to the skeleton structure of the side of the vehicle body 200.
[0047] The solution of the present application includes a double-layer roof cover consisting of a lower roof cover 110 and an upper roof cover 120. The lower cross beam assembly of the lower roof cover 110 and the upper cross beam assembly of the upper roof cover 120 are respectively connected to the skeleton structures on both sides of the vehicle body 200. The connection and force transmission path between the roof structure 100 and the skeleton structure of the vehicle body 200 are increased through the lower cross beam assembly and the upper cross beam assembly, which can effectively improve the overall rigidity of the vehicle body 200.
[0048] In this application, the vehicle can be a split-type flying car, comprising a passenger cabin 210 and a rear cabin 220. The rear cabin 220 is used to accommodate a folded and stowed aircraft. The lower roof 110 of the roof structure 100 isolates the passenger cabin 210 from the rear cabin 220, providing an independent seating space for the passenger cabin 210. This effectively prevents passengers from accidentally touching the aircraft in the rear cabin 220, thereby improving riding safety. Furthermore, because the lower roof 110 isolates the passenger cabin 210 from the rear cabin 220, the vehicle's NVH performance can be improved.
[0049] NVH stands for Noise, Vibration, and Harshness, and is used to study and measure the auditory and tactile feedback of vehicles and other mechanical products during operation. NVH performance is a key performance indicator in the automotive industry, playing a vital role in improving ride comfort, reducing failure rates, and meeting regulatory requirements.
[0050] In the present application, the transverse direction X is also the width direction of the vehicle body, the longitudinal direction Y is also the length direction of the vehicle body, the front end is the end where the front of the vehicle is located, and the rear end is the end where the rear cabin is located.
[0051] See also Figure 1 and Figure 3 In the present application, the upper roof 120 is located on the top of the vehicle, and the outer surface of the upper roof 120 constitutes a portion of the outer surface of the vehicle's roof. The lower roof 110 is located below the upper roof 120, and a storage space is formed between the lower roof 110 and the upper roof 120. The lower roof 110 and the upper roof 120 are connected at the front end near the vehicle body 200. The storage space has a closed end near the front end of the vehicle body 200 and an open end 2011 near the rear end of the vehicle body 200. The open end 2011 is opposite to and communicates with the rear engine compartment 220 of the vehicle body 200.
[0052] With this arrangement, the longitudinal Y-shaped protruding accessories of the aircraft accommodated in the rear cabin 220 can extend from the open end 2011 into the accommodation space formed between the lower roof 110 and the upper roof 120. This not only fully utilizes the top space within the vehicle body 200, avoiding the need to conceal the longitudinal Y-shaped protruding accessories of the aircraft, but also improves the NVH performance of the vehicle.
[0053] The skeleton structure may be a door pillar or upright pillar of the vehicle side, such as an A-pillar, a B-pillar, and a C-pillar, or may be a frame of another configuration of the vehicle body.
[0054] In some embodiments, the lower cross beam assembly includes at least a front cross beam 111 and a lower tail cross beam 112, the front cross beam 111 is arranged close to the top of the vehicle body 200, and the lower tail cross beam 112 has a preset distance from the front cross beam 111 in the height direction Z of the vehicle body 200; the lower top cover plate 113 is connected between the front cross beam 111 and the lower tail cross beam 112 in the longitudinal direction Y; the two ends of the front cross beam 111 are connected to the first position 201 of the skeleton structure, and the two ends of the lower tail cross beam 112 are connected to the second position 204 of the skeleton structure.
[0055] The first position 201 is located at the front end of the frame structure of the side of the vehicle body 200, and the second position 204 is located at the rear end of the frame structure of the side of the vehicle body 200. The first position 201 and the second position 204 are provided on both sides of the frame structure in the transverse direction X. In some embodiments, both ends of the front cross beam 111 and the lower tail cross beam 112 can be connected to the frame structure by welding.
[0056] See also Figure 1 and Figure 4 In some embodiments, the first position 201 of the vehicle body 200 has a first frame 2011 extending toward the interior of the vehicle body along the transverse direction X, and both ends of the front cross beam 111 are welded to the first frames 2011 on both sides of the vehicle body at first welding portions 2012 .
[0057] See also Figure 1 and Figure 7 In some embodiments, the second position 204 has a second frame 2041 extending toward the interior of the vehicle body along the transverse direction X, and both ends of the lower tail beam 112 are welded to the first frames 2041 on both sides of the vehicle body at the second welding portions 2042 .
[0058] The lower crossbeam assembly also includes a first intermediate crossbeam located between the front crossbeam 111 and the lower tail crossbeam 112. Both ends of the first intermediate crossbeam are connected to a third position of the framework structure, which is located between the first position 201 and the second position 204 in the longitudinal direction Y. The first intermediate crossbeam is a reinforcement beam used to further enhance the rigidity of the lower roof 110 and increase the installation stability of the lower roof panel 113.
[0059] In some embodiments, the lower roof 110 further includes a lower longitudinal beam 114 extending in the longitudinal direction Y in the middle of the lower roof 110 . The ends of the lower longitudinal beam 114 are respectively connected to the front cross beam 111 and the lower tail cross beam 112 in the longitudinal direction Y. The front cross beam 111, the lower tail cross beam 112, the lower longitudinal beam, the first intermediate cross beam, and the lower roof panel 113 form an integrated structure. During assembly, this integrated structure can be welded to the side panel's skeletal structure.
[0060] In some embodiments, the lower roof panel 113 transitions upwardly and tilts toward the front cross member 111 near the front end of the vehicle body 200. A predetermined distance is provided between the lower roof panel 113 and the upper roof panel 122 near the rear end of the vehicle body 200. The upward tilt of the lower roof panel 113 from rear to front to the front cross member 111 provides more headroom for the passenger compartment 210.
[0061] In some embodiments, the upper cross member assembly includes an upper tail cross member 121, which is disposed near the top of the vehicle body 200 and faces the lower tail cross member 112 in the height direction Z of the vehicle body 200. An upper roof panel 122 is connected between the front cross member 111 and the upper tail cross member 121 in the longitudinal direction Y. The upper tail cross member 121 is connected at both ends to a fourth position 203 of the framework structure. The fourth position 203 is located directly above the second position 204 on the framework structure.
[0062] See also Figure 1 and Figure 6 In some embodiments, the fourth position 203 has a fourth frame 2031 extending toward the inner side of the vehicle body along the transverse direction X, and both ends of the lower tail beam 112 are welded to the fourth frames 2031 on both sides of the vehicle body at third welding portions 2032 .
[0063] In some embodiments, the upper crossbeam assembly further includes a second intermediate crossbeam 123 positioned between the front crossbeam 111 and the upper tail crossbeam 121. The ends of the second intermediate crossbeam 123 are connected to the fifth position 202 of the framework structure. The fifth position 202 is located directly above the third position on the framework structure. The upper roof panel 122 covers the front crossbeam 111, the second intermediate crossbeam 123, and the upper tail crossbeam 121. The second intermediate crossbeam 123 is a reinforcement beam, further enhancing the rigidity of the upper roof panel 120 and increasing the installation stability of the upper roof panel 122.
[0064] See also Figure 1 and Figure 5 In some embodiments, the fifth position 202 has a fifth frame 2021 extending toward the inner side of the vehicle body along the transverse direction X, and both ends of the lower tail beam 112 are welded to the fifth frames 2021 on both sides of the vehicle body at fifth welding portions 2022 .
[0065] In some embodiments, the second middle cross beam 123 and the upper tail cross beam 121 are provided with additional shock-absorbing materials, such as shock-absorbing rubber, which can further improve the NVH performance.
[0066] In this embodiment, during the assembly of the roof structure 100, the front cross member 111, the lower tail cross member 112, the lower longitudinal member 114, the first intermediate cross member, and the lower roof panel 113 form an integral structure. During assembly, this integral structure can be welded to the corresponding positions of the side panel frame structure. The upper tail cross member 121 and the second intermediate cross member 123 of the upper roof 120 are then welded to the frame structure, and finally the upper roof panel 122 is welded.
[0067] Compared with the single-layer roof in the related art, the roof structure 100 of the present application increases the connection path between the roof structure 100 and the side frame structure of the vehicle body 200, and effectively disperses the stress transmitted from the suspension through the lower crossbeam assembly and the upper crossbeam assembly, thereby improving the rigidity and NVH performance, providing passengers with a quieter riding experience.
[0068] The present application also provides a vehicle, which includes a vehicle body 200 and a roof structure 100 as described in the above embodiment, wherein the roof structure 100 is connected to a side structure of the vehicle body 200 .
[0069] The vehicle of the present application is provided with a passenger cabin 210 and a rear cabin 220. The rear cabin 220 is used to accommodate an aircraft in a folded and retracted state. The lower top cover 110 of the roof structure 100 isolates the passenger cabin 210 from the rear cabin 220, thereby providing an independent riding space for the passenger cabin 210, effectively preventing passengers from accidentally touching the aircraft in the rear cabin 220, and improving riding comfort and safety.
[0070] The embodiments of the present application have been described above. The above description is illustrative and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
