[0036] Reference will now be made in detail to various specific embodiments of the present invention, examples of which are presented in the accompanying drawings and described below. Although the present invention will be described in conjunction with exemplary embodiments thereof, it should be appreciated that this description is not intended to limit the present invention to those exemplary embodiments thereof. On the other hand, the present invention is intended to cover not only the exemplary embodiments thereof, but also various alternative forms, modifications, equivalent forms, and other embodiments that may be included within the spirit and scope of the present invention as defined by the appended claims.

[0037] Hereinafter, a front side structure of a cargo box of a vehicle according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0038] The front side structure of the cargo box of a vehicle according to an exemplary embodiment of the present invention includes: a side outer panel 21, a side inner panel 22, a front guard 31 and a front side member 33, wherein the side outer panel 21 is provided on the outer side of the cargo box 13 to form the exterior of the cargo box 13, and the cargo box 13 is provided on the rear side of the cab 12 where passengers enter the vehicle 1, the side inner panel 22 is provided on the inner side of the side outer panel 21 in the cargo box 13, the front guard 31 is provided at the upper end portion of the front portion of the cargo box 13 along the width direction of the vehicle 1, and the front side member 33 is provided at the front end portion of the side portion of the cargo box 13, wherein the side end portions of the front side member 33 and the side end portions of the front guard 31 can be fastened together to the front end portion of the cargo box 13, and the lower end portion of the front side member 33 can be fastened to the end portion of the first floor member 35, which is provided at the lower end portion of the front portion of the cargo box 13.

[0039] Figure 2 1 shows a front side structure of the cargo box 13 of the vehicle 1 according to an exemplary embodiment of the present invention. Figure 1 In a vehicle 1 such as a pickup truck, a cab 12 into which passengers enter is provided on an upper portion of a frame 11 extending in a longitudinal direction of the vehicle 1 , and a cargo box 13 for loading or unloading cargo may be provided on a rear side of the cab 12 .

[0040] The front side structure of the cargo box of a vehicle according to the exemplary embodiment of the present invention may be applied to the cargo box 13 of a small truck such as a pickup truck.

[0041] The sides of the cargo box 13 may be formed using side outer panels 21 and side inner panels 22 .

[0042] The side outer panels 21 may be provided on the outside of the cargo box 13 to form the exterior of the cargo box 13 .

[0043] The side inner panel 22 may be provided on the inner side of the side outer panel 21 .

[0044] The side outer panel 21 and the side inner panel 22 may be disposed to be spaced apart from each other, and upper end portions of the side outer panel 21 and the side inner panel 22 may be fastened to each other.

[0045] Here, refer to Figure 2 The basic form of the cargo box 13 can be formed by a floor panel 30A on which cargo is loaded and forms the floor of the cargo box 13, a front panel 30B for closing the front end of the cargo box 13, and a tail panel 14 arranged at the rear end of the cargo box 13 so as to be openable or closable.

[0046] Furthermore, a member that can reinforce the rigidity of the cargo box 13 may be additionally applied, thereby increasing the rigidity of the cargo box 13. The metal plate may be bent in a direction perpendicular to the longitudinal direction, or may be formed into a closed cross-sectional structure so that the rigidity of a single member applied for rigidity reinforcement can be increased, and then the rigidity reinforcing member may be applied to reinforce the rigidity of the cargo box 13.

[0047] Meanwhile, hereinafter, two members being fastened means that the two members may be fastened to each other using welding (W) or bolts (B).

[0048] In an exemplary embodiment of the present invention, the rigidity of the front side portion of the cargo box 13 , that is, the rigidity of the portion where the front ends of the side outer panels 21 and the side inner panels 22 and the front panel of the cargo box 13 may contact each other in the cargo box 13 , may be improved.

[0049] First, the side upper member 32 may be provided at the upper end portion of the cargo box 13 in the longitudinal direction of the vehicle 1. The side upper member 32 may be formed to include an open lower portion, an upper portion, and two side portions, the cross section of which is bent at right angles, so that the side upper member 32 can support the upper end portion of the cargo box 13.

[0050] The front side member 33 may be provided at a front end portion of a side portion of the cargo box 13 .

[0051] The front side members 33 can be disposed between the side outer panels 21 and the side inner panels 22 at the front ends of the sides of the cargo box 13. The front side members 33 can be formed substantially along the height direction of the vehicle 1. Due to the wheel housings 23, the upper portions of the front side members 33 protrude outward from the cargo box 13, while the lower portions of the front side members 33 protrude inward from the cargo box 13. Therefore, the front side members 33 can be formed in such a way that the upper and lower portions of the front side members 33 protrude in opposite directions. The front side members 33 can be disposed so as to surround the side inner panels 22.

[0052] The upper end of the front side member 33 can be fastened to the side upper member 32. In this case, in the side upper member 32, the front side member 33 can be fastened to the inside of the cargo box 13, and the upper end of the side inner panel 22 can be located between the side upper member 32 and the front side member 33.

[0053] Therefore, the upper end portion of the front portion of the cargo box 13 can have a strong and sturdy structure.

[0054] The front side members 33 may be fastened to ends of the first floor member 35, the lower end of which is disposed at the lower end of the front portion of the cargo box 13. The front side members 33 and the first floor member 35 may form a "U"-shaped structure, and the upper end of the front side members 33 may be fastened to the front end of the side upper members 32, so that the front end of the side upper members 32 has a strong structure.

[0055] The first floor member 35 may be fastened to the frame 11 of the vehicle 1. A frame mount 11a may be formed to protrude from the frame 11 and may be fastened to the bottom of the first floor member 35 so that the first floor member 35 may be fastened to the frame 11.

[0056] The first floor member 35 may be fastened to the front side members 33 above the portion fastened to the frame 11. Since the first floor member 35 includes an inverted shape, the distance between the portion of the first floor member 35 mounted on the frame 11 and the portion of the first floor member 35 mounted on the front side members 33 may be minimized, thereby achieving a strong structure.

[0057] The front ends of the side upper members 32 can also be fastened to the side ends of the front guard 31, which is provided at the upper portion of the front end of the cargo box 13 along the width direction of the vehicle 1. At the same time, since the front ends of the side upper members 32 are also fastened to the upper ends of the front side members 33, the front ends of the side upper members 32, the side ends of the front side members 33, and the side ends of the front guard 31 can be fastened together at the front end of the cargo box 13 (see FIG. Figure 5 ).

[0058] Since the flange 33a is formed along the periphery of the front side member 33, the front side member 33 can be fastened to the side upper member 32 and the front guard 31 by the flange 33a. In this case, the hook 15 fastened to the side upper member 32 may not be fastened to the front guard 31, and may be fastened only to the side upper member 32 (see FIG. Figure 5 ).

[0059] Meanwhile, the side end portions of the front shield 31 may be bent toward the front side of the vehicle 1 , and the bent portions may be fastened to the side upper members 32 and the front side members 33 .

[0060] In the cargo box 13, the second floor member 36, the third floor member 37 and the fourth floor member 38 can be set to be set along the width direction of the vehicle 1 from the first floor member 35 toward the rear side of the vehicle 1, or can be set to extend upward in a state of being set along the width direction of the vehicle 1.

[0061] Both end portions of the second floor member 36 may be fastened to the wheel housing 23 .

[0062] The third floor member 37 may be formed to extend in the width direction of the vehicle 1 and then extend upward behind the second floor member 36. The ends of the third floor member 37 may be fastened to the side upper members 32 so that the third floor member 37 supports the side upper members 32 in the middle portion of the cargo box 13.

[0063] The fourth floor member 38 may be provided at a rear end portion of the cargo box 13 in the width direction of the vehicle 1 and may be fastened to a lower end portion of a D-pillar 34 that supports the tailgate 14 at the rear end portion of the cargo box 13 .

[0064] According to the front side structure of the vehicle cargo box, by fastening the floor member and the front guard to the portion where the side and front sides of the vehicle cargo box intersect, the rigidity of the portion where the side and front sides of the cargo box intersect can be improved.

[0065] Therefore, even when a load is applied to the portion where the side and front sides of the cargo box intersect due to a collision or the like, deformation of the upper portion of the cargo box can be prevented or minimized.

[0066] In an exemplary embodiment of the present invention, a vehicle may be referred to as a concept based on various means of transportation. In some cases, a vehicle may be interpreted as a concept based on a concept that includes not only various land vehicles traveling on roads, such as cars, motorcycles, trucks, and buses, but also various means of transportation such as airplanes, drones, ships, and the like.
