[0067] Figure 3 is a perspective view of a fender apron structure according to an embodiment of the present invention.

[0068] Referring to Figures 1 to 3 According to an embodiment of the present invention, the fender apron structure 20 can include: a front side member 30; an upper member 40 disposed on the front side member 30; a radiator side member 50 connected to the front side member 30; an upper headlamp support member 70 connecting the radiator side member 50 and the upper member 40; and a side upper reinforcement member 90 connecting a connection portion between the front side member 30 and the radiator side member 50 and a connection portion between the upper member 40 and the upper headlamp support member 70.

[0069] A headlamp mounting portion 80 for mounting a headlamp 110 can be formed between the radiator side member 50, the upper headlamp support member 70, and the side upper reinforcement member 90.

[0070] The radiator side member 50, the upper headlamp support member 70, and the side upper reinforcement member 90 can form an inverted triangular shape.

[0071] That is, the radiator side member 50, the upper headlamp support member 70, and the side upper reinforcement member 90 can be combined into a stable triangular shape, and the headlamp 110 can be mounted on the headlamp mounting portion 80.

[0072] The radiator side member 50 and the front side member 30 can form a first impact load path P1, and the radiator side member 50, the upper headlamp support member 70, and the upper member 40 can form a second impact load path P2. The radiator side member 50, the side upper reinforcement member 90, and the upper member 40 can form a third impact load path P3.

[0073] The fender apron structure 20 according to one embodiment of the present application has three impact load paths to distribute impact loads, and the headlamp mounting portion 80 cushions impact in the event of a collision of the vehicle, and also functions as a space for mounting the headlamp 110.

[0074] The turn signal lamp 120 can be mounted on the upper lamp support member 70.

[0075] The fender apron structure 20 according to one embodiment of the present application can cope with strengthened collision load regulations, and can mount separate detachable vehicle lamps including the headlamp 110 and the turn signal lamp 120 without a separate bracket.

[0076] Figure 4 is an exploded perspective view of a radiator side member that can be applied to the fender apron structure according to one embodiment of the present application, Figure 5 is a partial perspective view of a radiator side member that can be applied to the fender apron structure according to one embodiment of the present application, Figure 6 is a cross-sectional view along line VI-VI in Figure 4 .

[0077] Referring to Figures 4 to 6 , the radiator side member 50 can include a lower body 52 engaged with the front side member 30, and an upper body 54 engaged with the upper lamp support member 70, and having a width narrower than that of the lower body 52.

[0078] The radiator side member 50 can include a radiator front plate portion 56 arranged in front of the vehicle, and a radiator side plate portion 58 bent at the front plate portion 56 to form a side surface. The strength of the radiator side member 50 can be increased by the bent shape of the radiator side member 50.

[0079] The radiator side member 50 can further include a radiator upper plate portion 60 bent at the front plate portion 56 to form an upper surface. The bent radiator upper plate portion 60 can increase the strength of the radiator side member 50.

[0080] The fender apron structure 20 according to one embodiment of the present application can further include a lamp support bracket 62 formed in a "U" shape to connect the radiator side plate portion 58 and the radiator upper plate portion 60. The strength of the upper portion of the radiator side member 50 can be improved by connecting the radiator side plate portion 58 and the radiator upper plate portion 60 using the lamp support bracket 62. Since the lamp support bracket 62 can be assembled using bolts or rivets, a welding work of the radiator side plate portion 58 and the radiator upper plate portion 60 is not required, thereby simplifying the manufacturing process.

[0081] Figure 7 is a perspective view of an upper light support member which can be applied to the fender apron structure according to an embodiment of the present application, Figure 8 is a cross-sectional view along line VII-VII of Figure 7 .

[0083] The curvature of the support inner surface 74 and the support outer surface 76 can increase the strength of the upper light support member 70. In addition, the support inner surface 74 is formed shorter than the support outer surface 76, thereby providing an open cross section for assembling the upper light support member 70.

[0084] In the upper light support member 70, a support hole 77 for connecting the radiator support upper member 130, a signal lamp hole 78 for mounting the turn signal lamp 120, and a headlamp hole 79 for mounting the headlamp 110 can be formed.

[0085] Accordingly, according to the fender apron structure according to an embodiment of the present application, the headlamp 110 and the turn signal lamp 120 can be mounted without separate brackets.

[0087] Referring to Figure 3 , Figures 9 to 11 , the side upper reinforcement member 90 can include a longitudinal portion 92 connected to the radiator side member 50 and an inclined portion 94 connected to the upper member 40. In the event of a collision of the vehicle, the longitudinal portion 92 transmits a portion of impact load transmitted from the radiator side member 50 to the front side member 30, and the inclined portion 94 transmits a portion of impact load transmitted from the radiator side member 50 to the upper member 40.

[0088] The side upper reinforcement member 90 can include a reinforcement body portion 96 and a reinforcement side portion 98 bent from the reinforcement body portion 96. The bent reinforcement side portion 98 can increase the strength of the side upper reinforcement member 90.

[0089] Figures 12 to 15 is a schematic view of a manufacturing method of a vehicle body including a fender apron structure according to an embodiment of the present application.

[0090] Hereinafter, referring to Figures 12 to 15 , a manufacturing method of a vehicle body including a fender apron structure according to an embodiment of the present application will be described.

[0091] Referring to Figure 12 , the side upper reinforcement member 90 and the upper member 40 are coupled to the front side member 30 by welding.

[0092] Referring to Figure 13 , the radiator side member 50 is welded to the front side member 30 and the side upper reinforcement member 90.

[0093] Referring to Figure 14 , the upper portion of the radiator side member 50 and the upper member 40 are welded to each other by the upper headlamp support member 70 to form an inverted triangular pole-shaped path.

[0094] Referring to Figure 15 , the upper portion of the fender apron structure 20 disposed on both sides in front of the vehicle is connected with the radiator support upper member 130, which can be done by bolt coupling.

[0095] The fender apron structure according to an embodiment of the present application and the vehicle body including the same can effectively disperse impact loads without requiring an additional crash response structure, and can install a detachable vehicle lamp having a separate headlamp and a turn signal lamp. Accordingly, manufacturing costs and weight can be reduced.

[0096] That is, as Figure 15 indicated, when a vehicle collision occurs, loads are properly distributed in the arrow direction, and thus the safety of an occupant can be improved.
