Detailed Description

Fig. 1 is a perspective view of a partial structure of a vehicle according to an embodiment of the present invention, in which axial directions X, Y, and Z are shown. FIG. 2 is a cross-sectional view of the vehicle of FIG. 1 taken along line I-I. Referring to fig. 1 and 2, a vehicle side rail structure 100 of a vehicle 10 of the present embodiment includes a side rail 110 and a partition member 120. The side member 110 is located at a side of a lower portion of the vehicle 10 and extends in the front-rear direction of the vehicle 10 (i.e., a direction parallel to the axial direction Y). The side member 110 includes an outer member 112 and an inner member 114, the outer member 112 is located outside the inner member 114 in the width direction of the vehicle 10 (i.e., the direction parallel to the axial direction X), and the outer member 112 and the inner member 114 constitute a closed cross section as shown in fig. 2. The partition member 120 is disposed in the closed cross section formed by the outer beam 112 and the inner beam 114 and extends in the width direction of the vehicle 10 (i.e., the direction parallel to the axial direction X).

The peripheral edge of the partition member 120 has a plurality of flanges P that extend in the front-rear direction of the vehicle 10 (i.e., in a direction parallel to the axial direction Y) to constitute a plurality of joint portions (shown as a plurality of first joint portions 134 and second

joint portions

132A, 132B, 132C, 132D). The second

joint portions

132B, 132C are located on a side wall 1101 of the side member 110 on the outer side in the width direction of the vehicle 10 (i.e., the direction parallel to the axial direction X), the second joint portion 132A is located on an upper wall 1102 of the side member 110, the second joint portion 132D is located on a lower wall 1103 of the side member 110, and the first joint portion 134 is located on a side wall 1104 of the side member 110 on the inner side in the width direction of the vehicle 10 (i.e., the direction parallel to the axial direction X). The side walls 1101, upper wall 1102, and lower wall 1103 are comprised by, for example, the outer beam 112, and the side walls 1104 are comprised by, for example, the inner beam 114. In addition, the vehicle side member structure 100 further includes a foam filler 130, and the foam filler 130 is disposed in a space between the side member 110 and the partition member 120 and between the flange P and the side member 110. The space is located between the second

joint portions

132A, 132B, 132C, 132D and the first joint portion 134 in the circumferential direction of the axis a of the side member 110.

In the above arrangement, the partition member 120 is joined to the side member 110 at the plurality of joining portions (the first joining portion 134 and the second joining

portions

132A, 132B, 132C, 132D), and the space between the partition member 120 and the side member 110 is filled with the foam filler 130. Accordingly, the joint strength between the partition member 120 and the side member 110 is improved and no gap exists, and the impact force applied to the side member 110 can be smoothly transmitted to the partition member 120. Thus, the vehicle side rail structure 100 of the present embodiment can suppress deformation and collapse of the side rail 110 at the time of an impact.

Fig. 3 is a perspective view of the vehicle side frame structure of fig. 2. For clarity of the drawing, the foaming filler 130 in fig. 2 is not shown in fig. 3. Referring to fig. 2 and 3, the side member 110 of the present embodiment has a plurality of ridge lines L extending in the front-rear direction of the vehicle 10 (i.e., in the direction parallel to the axial direction Y). Each ridge line L is located between two joint portions (i.e., two adjacent joint portions of the first joint portion 134 and the second

joint portions

132A, 132B, 132C, 132D) in the circumferential direction of the axis a of the side member 110, and the foam filler 130 is disposed along the circumferential direction of the axis a of the side member 110 so as to overlap the ridge lines L. Accordingly, the foamed filler 130 fills the gap between the side member 110 and the partition member 120 at the ridge line L between the joint portions, so that the impact force applied to the ridge line L by the side member 110 can be smoothly transmitted to the partition member 120.

In the present embodiment, the partition member 120 is joined to the inner beam 114 at the first joint 134, for example, by welding, and the partition member 120 is joined to the outer beam 112 at the

second joint

132A, 132B, 132C, 132D, for example, by an adhesive. Since the partition members 120 are fixed to the outer beams 112 with the dense ridge lines L by bonding as described above, rather than fixing the partition members 120 by welding which requires a large flat surface, a larger number of joint portions (i.e., the second

joint portions

132A, 132B, 132C, 132D) may be provided at the outer beams 112 to achieve a stable joint effect.

As described above, in the vehicle side member structure of the present invention, the partition member is joined to the side member by the plurality of joining portions, and the space between the partition member and the side member is filled with the foam filler. Accordingly, the joint strength between the partition member and the side member is improved without a gap, and the impact force applied to the side member can be smoothly transmitted to the partition member. Thus, the utility model discloses a deformation and subside when vehicle curb girder structure can restrain the curb girder and receive the striking.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications or substitutions do not depart from the scope of the embodiments of the present invention, and the essence of the corresponding technical solutions is that.
