[0002] Recently, modular vehicle bodies have been developed and applied to support the trend toward electric vehicles and the need to reduce manufacturing costs.

[0003] Specifically, for plate parts for vehicles, since these plate parts are made into an integrated single plate form by stretching or forming stretching, the length (front-rear length, left-right length, and up-down length) of the integrated plate cannot be changed when the type of vehicle changes, and therefore, it is impossible to make it universal, and specifically, because the entire design needs to be changed, the mold needs to be changed. Therefore, according to the concept of the smart factory, this has a limitation in manufacturing vehicles, thereby resulting in the disadvantage of excessive manufacturing costs.

[0004] Therefore, for some parts in the vehicle where multiple panel parts are used, it is necessary to change the design to a structure composed of several separate parts rather than an integrated panel structure so that the length can be changed when necessary and the commonality can be maximized.

[0005] For this purpose, recently, a vehicle body having a space frame structure in which a roof frame, a fender, a side seal, and the like of a vehicle are coupled to make a vehicle body after being manufactured into a tubular shape by intrusion.

[0006] When the vehicle body is manufactured as a space frame structure as described above, the existing side outer reinforcement has no structure for sufficiently supporting the tubular roof rack and has no structure for connecting the tubular fender and the side seal, and therefore, there is a defect that the rigidity of the entire vehicle body is low.

[0029] Hereinafter, a side outer reinforcement panel of a vehicle according to an exemplary embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

[0030] refer to Figure 1 and Figure 2 The roof rack 10 of the vehicle includes: a roof side pipe 13 formed with a closed section and extending rearward from both sides of a front wall 11 located at the front of the vehicle to both sides of a rear roof beam 12, and the roof side pipe 13 is provided on both sides of the vehicle body; and one or more intermediate roof beams 14 formed with a closed section and extending in the lateral direction of the vehicle, and the one or more intermediate roof beams connect the roof side pipe 13 at both sides between the front wall 11 and the rear roof beam 12.

[0031] That is, the front pillar (A-pillar) and the roof side member, which are usually separate parts in the related art, are integrally formed into one part by the roof side pipe 13 having a hollow closed cross-section, and similarly, the front cowl 11, the middle roof rail 14, and the rear roof rail 12, each having a hollow closed cross-section structure, are sequentially coupled to the roof side pipe 13 from the front of the vehicle to the rear, thereby Figure 1 As shown, the roof rack 10 has an integral space frame structure.

[0032] Specifically, the closed section of the roof side tube 13 is manufactured by hydroforming or hot blowing to form one tube, rather than combining two or more plates by welding or the like as in the related art, thereby realizing a space frame structure.

[0033] The roof side pipe 13 having the above-described structure can be easily applied to other kinds or models of vehicles by longitudinally extending or contracting.

[0034] By sequentially connecting four or more straight portions via curved portions, the closed cross-section of the roof side tube 13 can have a single closed curve.

[0035] For example, in Figure 2 In the illustrated embodiment, the roof side tube 13 has a closed curved shape by sequentially connecting a total of four straight portions via bent portions.

[0036] Therefore, the closed cross-sectional shape of the roof side pipe 13 has a rectangular structure, whereby the roof side pipe 13 can be easily brought into surface contact with adjacent parts, thereby improving the matching and assembly degree of parts.

[0037] In addition, since the cross-sectional shape of the roof side tube 13 is a rectangular shape, a relatively wide cross-sectional area can be ensured in a space allowing the cross-sectional shape of the roof side tube 13 to be accommodated, thereby further improving the rigidity and strength of the roof side tube 13 .

[0038] While easily ensuring a surface contact state with adjacent parts in the front-rear direction of the vehicle body by maintaining four straight portions and a curved portion of a closed cross section, the roof side tube 13 gradually changes into a shape that occupies as much as possible a space formed in a side outer panel 21 provided outside the roof side tube 13.

[0039] As described above, since the roof side pipe 13 easily ensures surface contact with adjacent parts, the assembly degree of the vehicle body is improved. In addition, since the cross-sectional area of ​​the roof side pipe 13 is increased to the maximum within the allowable range, the strength and rigidity of the roof side pipe 13 are improved.

[0040] Only the cross-sectional shape of the roof side pipe 13 can be gradually changed into a desired shape according to the position of the cross-sectional area maintained in the vehicle front-rear direction.

[0041] In addition, the closed cross section of the roof side pipe 13 can be regarded as a structure protruding from the inner straight portion 13 a of the vehicle body in a shape such that the other straight portion occupies the inner space of the side outer panel 21 as much as possible.

[0042] Such a cross-sectional structure of the roof side tube 13 as described above makes it possible to easily ensure a surface contact state with adjacent parts, increase strength and rigidity by increasing the cross-sectional area of ​​the roof side tube, and further improve the rigidity and strength of the roof rack for the vehicle by most easily and firmly combining the cowl 11, the intermediate roof rail 14, and the rear roof rail 12 coupled in the roof side tube 13.

[0043] Both ends of each of the cowl 11, the center roof rail 14, and the rear roof rail 12 can be in vertical ground contact with the inner straight portion 13a of the roof side pipe 13, so they can be easily assembled and combined, and high strength and high rigidity can be ensured compared to when they are coupled to the roof side panel 13 at an angle.

[0044] The side outer panel 21 is positioned outside the roof side tube 13 and may be made of a material such as plastic, so the appearance of the vehicle can be freely manufactured.

[0045] The front pillar trim 22 is installed inside the roof side tube 13 , and an air bag 23 , a wire ring (support ring) 24 , etc. may be installed in a space formed between the front pillar trim 22 and the roof side tube 13 .

[0046] Meanwhile, the one or more intermediate roof rails 14 include a first roof rail 14 a installed at a position supporting an upper end of the front windshield glass 25 .

[0047] That is, the center roof rail 14 must include the first roof rail 14 a , and may further include or exclude an additional center roof rail 14 depending on the kind or model of the vehicle.

[0048] For reference, in Figure 1 The first embodiment shown includes a second roof rail 14 b as an additional intermediate roof rail 14 .

[0049] As described above, each of the first roof beam 14 a and the second roof beam 14 b may be coupled such that both ends are in vertical ground contact with the inner straight portion 13 a of the roof side tube 13 .

[0050] The rear roof rail 12 extends in the transverse direction of the vehicle while forming a closed cross section having one or more closed curves, and both ends of the rear roof rail may be coupled to vertically contact the inner straight portion 13 a of the roof side pipe 13 .

[0051] The first and second roof beams 14a and 14b of the intermediate roof beam 14 and the rear roof beam 12 are formed so that a predetermined closed cross section extends in the transverse direction of the vehicle, can be manufactured by roll forming or variable extrusion of aluminum, and can be easily changed in length, so they can be easily applied to other kinds or models of vehicles.

[0052] That is, by adjusting the lengths of the cowl 11, the center roof rail 14, and the rear roof rail 12 in the vehicle transverse direction and the length of the roof side pipe 13 in the vehicle longitudinal direction, the above-mentioned roof rack 10 can be easily applied to other kinds or models of vehicles and can be easily commonly used for a variety of vehicles, so that new types of vehicles can be more easily developed, and they can be effectively applied in a manner of manufacturing various products in small quantities.

[0053] Furthermore, since the above-described roof rack 10 has a space frame in which all parts are connected to each other in a tubular shape as described above, it is possible to ensure relatively high rigidity with a relatively small weight.

[0054] A roof panel 26 made of plastic is coupled to the top of the roof bar 10 , thereby completing the roof of the vehicle.

[0055] For reference, the front wall 11, the middle roof rail 14, and the rear roof rail 12 are vertically coupled to the inner straight portion 13a of the roof side pipe 13 by welding in a surface contact manner, wherein CO 2 Welding or laser welding.

[0056] In the embodiment according to the present disclosure, similarly to the roof rack 10 , the fender 30 and the side seal 40 provided at the front of the vehicle are formed in a space frame structure, wherein the fender and the side seal are manufactured in a tubular shape and connected.

[0057] The roof rail 10 , the dash panel 30 , and the side seal 40 are all formed by extrusion so that they have a lattice structure cross section or a honeycomb cross section, so the rigidity and strength of the vehicle body can be improved by the lattice structure cross section or the honeycomb cross section.

[0058] like Figures 1 to 10 As shown, the side outer reinforcement plate 50 of the vehicle according to the embodiment of the present disclosure is coupled to the vehicle body of the space frame structure, the vehicle body includes a roof frame 10 manufactured in a tubular shape, a fender 30 and a side seal 40, and the side outer reinforcement plate of the vehicle includes: an upper flange 51, which extends in the front-rear direction of the vehicle, is connected to the roof frame 10 and supports the roof frame 10; a lower flange 52, which extends in the front-rear direction of the vehicle and is connected to the side seal 40; a front pillar (A pillar) 53, which connects the upper flange 51 and the lower flange 52 in the up-down direction and is connected to the fender 30; and a center pillar 54 (B pillar), which is arranged behind the front pillar 53, connects the upper flange 51 and the lower flange 52 in the up-down direction, and has an upper end connected to the roof frame 10 and a lower end connected to the side seal 40.

[0059] like Figure 2 As shown, a lower portion of the upper flange 51 overlaps with a lower portion of the side outer panel 21 , and thus the weather strip 27 may be coupled to this portion.

[0060] In addition, Figure 2 As shown in FIG. 1 , the upper flange 51 of the side outer reinforcement panel 50 is coupled with the lower end of the roof side pipe 13 of the roof rail 10 in a surface-contact manner in the front-rear direction of the vehicle.

[0061] That is, the upper end of the upper flange 51 is coupled with the inner straight portion 13 a of the roof side pipe 13 of the roof rail 10 in a surface contact manner by welding, and thus a high coupling force can be ensured.

[0062] like Figure 3 and Figure 4 As shown, the front end of the front pillar 53 of the side outer reinforcement plate 50 is directly coupled to the outer side of the fender 30 of the vehicle, the rear end of the front pillar 53 is coupled to the rear end of the connecting bracket 61, and the front end of the connecting bracket 61 is coupled to the inner side of the fender 30, whereby a space surrounded by the front pillar 53, the connecting bracket 61 and the fender 30 forms a closed cross section. Therefore, strength and rigidity can be ensured.

[0063] In addition, if Figure 1 and Figures 5 to 7 As shown in FIG. 1 , the center pillar 54 of the side outer reinforcement panel 50 includes a center pillar outer panel 54 a and a center pillar inner panel 54 b .

[0064] The center pillar outer panel 54 a has an upper end that is in surface contact with the roof side pipe 13 of the roof rail 10 and a lower end that is in surface contact with the side seal 40 .

[0065] The center pillar inner panel 54 b has an upper end in surface contact with the roof side pipe 13 of the roof rail 10 and a lower end coupled to an upper end of the center pillar inner lower panel 62 , and a lower end of the center pillar inner lower panel 62 in surface contact with the side seal 40 .

[0066] Therefore, a space surrounded by the roof side tube 13, the center pillar outer panel 54a, the center pillar inner panel 54b, the center pillar inner lower panel 62, and the side seal 40 forms a closed cross section, and thus strength and rigidity can be ensured.

[0067] The embodiment of the present disclosure further includes a glass support 55 extending in the front-rear direction of the vehicle, and as shown in FIG. Figure 2 As shown, the glass support is positioned above the upper flange 51 and has one end in surface contact with the inner support portion 13 a of the roof side pipe 13 of the roof rail 10 and the other end overlapping the side outer panel 21 and supporting the front windshield 25 .

[0068] Since the lower portion of the front windshield glass 25 is supported by the glass supporter 55 , the front windshield glass 25 can be mounted with a stronger coupling force.

[0069] like Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, the embodiment of the present disclosure further includes a first reinforcement portion 57 and a second reinforcement portion 58 extending in the front-rear direction of the vehicle, positioned above the upper flange 51 , and each having one end in surface contact with the roof side pipe 13 of the roof rail 10 .

[0070] At the portions where the first reinforcement portion 57 and the second reinforcement portion 58 overlap with the first roof rail 14a and the second roof rail 14b of the roof bar 10, the other end of the first reinforcement portion 57 and the other end of the second reinforcement portion 58 overlap with the top and bottom surfaces of the first roof rail 14a and the second roof rail 14b, respectively, so that the strength and rigidity can be further improved.

[0071] In addition, if Figure 5 , Figure 8 and Fig.10 As shown, at portions of the first reinforcement portion 57 and the second reinforcement portion 58 that do not overlap with the first roof beam 14a and the second roof beam 14b, the other ends of the first reinforcement portion 57 and the second reinforcement portion 58 overlap with each other and are coupled to the roof panel 26 through the connecting member 63, thereby improving the strength and rigidity of the roof panel 26.

[0072] The side outer reinforcement plate 50 according to the embodiment of the present disclosure described above is coupled to a vehicle body of a space frame structure including the roof rail 10, the fender 30, and the side seal 40 manufactured in a tubular shape, thereby supporting the roof rail 10 and being firmly coupled to the fender 30 and the side seal 40. Therefore, there is an advantage that the strength, rigidity, and durability of the vehicle body having the space frame structure can be significantly improved.

[0073] Although the present disclosure has been described with reference to the specific embodiments shown in the accompanying drawings, it will be apparent to those skilled in the art that the present disclosure can be changed and modified in various ways without departing from the scope of the present disclosure described in the appended claims.
