[0035] Figure 1 is a lower view of a partial structure of a vehicle according to an embodiment of the present application, which shows the axial directions X, Y, Z. Referring to Figure 1 , the side structure 100 of the vehicle 10 according to the embodiment includes two side rails 110 and two rear frames 120. The side rails 110 extend along the front-rear direction (axial direction Y) of the vehicle 10 on the outer sides in the width direction (axial direction X) of the vehicle 10. The rear frames 120 connect a bumper beam 12 of the vehicle 10 and the side rails 110, the bumper beam 12 being located rearward of the side rails 110 in the front-rear direction (axial direction Y) of the vehicle 10 and upward of the side rails 110 in the up-down direction (axial direction Z) of the vehicle 10.

[0036] Figure 2 is a partial perspective view of the vehicle of Figure 1 . Referring to Figure 2 , the side structure 100 of the vehicle 10 further includes a center pillar 130, which is connected to the side rails 110 and extends upward. The rear frames 120 have a side rail connecting portion 122 and a center pillar connecting portion 124, the side rail connecting portion 122 being connected to the rear ends of the side rails 110, and the center pillar connecting portion 124 being connected to the center pillar 130 forward of the side rail connecting portion 122 in the front-rear direction (axial direction Y) of the vehicle 10.

[0037] As described above, in the side structure 100 of the vehicle 10 of the present embodiment, the rear frame 120 is connected to the side frame 110 at the rear end thereof not only through the side frame connecting portion 122 thereof but also through the pillar connecting portion 124 thereof in front of the side frame connecting portion 122. Accordingly, when a rear collision load is transmitted to the rear frame 120 and the side frame 110, the pillar 130 can stably support in front of the rear frame 120 and the side frame connecting portion 122, so that the rear frame 120 is not easily overturned forward. Thus, the side structure 100 of the vehicle 10 of the present embodiment can prevent the rear frame 120 from being overturned forward when the vehicle 10 is subjected to a rear collision.

[0038] Figure 3 is a side view of a part of the vehicle of Figure 2 Please refer to Figures 1 to 3 In the present embodiment, the rear frame 120 has a straight portion 126 extending in the front-rear direction (axial direction Y) of the vehicle 10, and the straight portion 126 is connected to the bumper beam 12. As shown in Figure 3 , the pillar connecting portion 124 of the rear frame 120 is at least partially located at the same height as the straight portion 126 of the rear frame 120 in the up-down direction (axial direction Z) of the vehicle 10. Accordingly, by connecting the pillar connecting portion 124 to the pillar 130 at a position corresponding to the height of the straight portion 126, the rear frame 120 can be surely prevented from being overturned forward when subjected to a rear collision.

[0039] Figure 4 is a sectional view of a part of the vehicle of Figure 3 Please refer to Figure 4 In the present embodiment, the side frame connecting portion 122 of the rear frame 120 is connected to the top surface 110a of the side frame 110. Accordingly, a rear collision load applied to the rear frame 120 can be transmitted from the top surface 110a of the side frame 110 to the side frame 110, so that the side frame 110 can prevent the rear frame 120 from being rotated forward, and thus effectively prevent the rear frame 120 from being overturned forward. Further, the straight portion 126 of the rear frame 120 is located rearward of the side frame 110 in the front-rear direction (axial direction Y) of the vehicle 10 as shown in Figure 3 , and is located inward of the side frame 110 in the width direction (axial direction X) of the vehicle 10 as shown in Figure 1 , and the side frame connecting portion 122 of the rear frame 120 is connected to the inner side surface 110b of the side frame 110 as shown in Figure 4 . Accordingly, the side frame 110 can prevent the rear frame 120 from being overturned inward in the width direction (axial direction X) of the vehicle 10 through the inner side surface 110b thereof.

[0040] Figure 5 is a sectional view of a part of the vehicle of Figure 3 Please refer toFigure 5 In the present embodiment, the pillar connecting portion 124 of the rear frame 120 is connected to the inner side surface 130a of the pillar 130 and the rear surface 130b of the pillar 130. Accordingly, the pillar 130 can prevent the rear frame 120 from turning to the inner side of the vehicle 10 in the width direction (axial direction X) by the inner side surface 130a thereof, and the pillar 130 can prevent the rear frame 120 from turning forward by the rear surface 130b thereof.

[0041] Please refer to Figure 1 The side structure 100 of the vehicle 10 of the present embodiment further includes a cross beam 140. The rear frame 120 has an inclined portion 128 inclined from the front end of the straight portion 126 to the outer side of the vehicle 10 in the width direction (axial direction X). The cross beam 140 is located behind the rear surface 110c of the rear end of the side rail 110 and connected to the two straight portions 126. Accordingly, when the vehicle 10 is subjected to a rear collision so that the inclined portion 128 of the rear frame 120 tends to turn to the inner side of the vehicle 10 in the width direction (axial direction X), the cross beam 140 can prevent the inclined portion 128 of the rear frame 120 from turning to the inner side of the vehicle 10 in the width direction (axial direction X), so that the rear frame 120 surely transmits the collision load from the rear of the vehicle 10 to the side rail 110.

[0042] In the present embodiment, the pillar connecting portion 124 of the rear frame 120 and the side rail connecting portion 122 of the rear frame 120 are integrally formed, for example, by a die casting process. Accordingly, the rear frame 120 as a whole has good structural rigidity and can effectively transmit the collision load through the pillar connecting portion 124 and the side rail connecting portion 122.

[0043] In summary, in the side structure of the vehicle of the present embodiment, the rear frame is connected to the pillar in front of the side rail connecting portion of the rear frame in addition to being connected to the rear end of the side rail through the side rail connecting portion. Accordingly, when the rear collision load is transmitted to the rear frame and the side rail, the pillar can stably support in front of the rear frame and the side rail connecting portion, so that the rear frame is not easily turned forward. Thus, the side structure of the vehicle of the present embodiment can prevent the rear frame from turning forward when the vehicle is subjected to a rear collision.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present embodiment, and are not intended to limit the present embodiment; although the present embodiment has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present embodiment.
