In addition, the high roof module 110 includes a trim mounting bracket 151 connected to the high roof side panel 131.

[0149] Here, the components of the high roof module 110 as described above can be assembled in an online process using a conveyor. Therefore, the high roof module 110 can be mass-produced.

[0150] In this state, the high roof modules 110 are assembled into a complete vehicle body assembly 15 which is transported along a conveyor in a separate in-line process.

[0151] To specifically describe the assembly process of the vehicle body complete assembly 15 and the high roof module 110 , the high roof side panel 131 of the high roof module 110 is loaded onto the upper portion of the side body welding portion 27 through the loading area 29 of the roof side body 20 .

[0152] The connecting flange 133 formed at the lower portion of the high roof side panel 131 is loaded to the upper portion of the side vehicle body welding portion 27. The second portion 215 of the roof mounting bracket 211 supports the inner surface of the high roof side panel 131 in the vehicle width direction.

[0153] Next, the connection flange 133 is connected to the upper portion of the side vehicle body welding portion 27 by welding, and the inner surface of the high roof side panel 131 is connected to the second portion 215 of the roof mounting bracket 211 by welding.

[0154] Through a series of processes as described above, the vehicle body 10 in which the high roof module 110 is assembled to the vehicle body complete assembly 15 is transported along the conveyor during the assembly process. In this process, the trim panel 171 is connected to the trim mounting bracket 151.

[0155] Therefore, according to the roof structure 100 of the vehicle body according to the embodiment assembled as described above, the high roof module 110 may be mounted on the vehicle body complete assembly 15 of various vehicle models through the roof mounting unit 210 .

[0156] The roof structure 100 of a vehicle body according to an embodiment can provide a wide interior space for a vehicle body complete assembly 15 through a high roof module 110 .

[0157] Furthermore, based on the roof structure 100 of the vehicle body according to one embodiment, the high roof module 110 is generally applicable to the vehicle body complete assembly 15 of various vehicle models.

[0158] For further explanation, the high roof side panel 131 of the high roof module 110 is connected to the side body weld 27 of the roof side body 20 by welding, which is generally provided in the vehicle body complete assembly 15 .

[0159] Therefore, since the high roof module 110 is generally applied to the vehicle body complete assembly 15 manufactured in various shapes according to the customized service type of the PBV, the development cycle of the PBV can be shortened, and the weight of the PBV can be reduced.

[0160] Therefore, according to the roof structure 100 of the vehicle body of one embodiment, separate design and components according to the type and requirements of the PBV are not required, and design and production costs can be reduced by applying common specifications and components.

[0161] Furthermore, the roof structure 100 of the vehicle body according to one embodiment can increase the roof strength and the vehicle body torsional strength by applying the high roof beam assembly 121 and the trim mounting bracket 151 to the high roof module 110 .

[0162] Furthermore, based on the roof structure 100 of the vehicle body according to one embodiment, since the high roof side panel 131 of the high roof module 110 partitions the inside and the outside of the vehicle body 10 , it is possible to prevent moisture from flowing into the inside of the vehicle body 10 .

[0163] Furthermore, based on the roof structure 100 of the vehicle body according to one embodiment, the trim mounting bracket 151 is coupled to the high roof beam assembly 121 and the roof mounting bracket 211 provided on the inner side of the vehicle body with the high roof side panel 131 therebetween.

[0164] Based on the roof structure 100 of the vehicle body according to one embodiment, the cross sections of the trim mounting bracket 151, the high roof side panel 131, the high roof beam assembly 121 and the roof mounting bracket 211 are sufficiently overlapped to ensure roof connectivity, thereby enhancing lateral strength and collision performance.

[0165] While embodiments of the present invention have been described in conjunction with what are presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
