Detailed Description
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
First, a vehicle lower portion structure 100 according to an embodiment of the present invention will be described with reference to fig. 1 and 2.
The vehicle lower portion structure 100 is located at the vehicle rear portion (Y2 direction side), and is provided with a jack portion. As shown in fig. 1, the vehicle lower portion structure 100 includes a rear cross member 1, a rear floor 2, and a jack bracket 3. Here, fig. 1 is a cross-sectional view perpendicular to the vehicle width direction (X direction) and including a surface of a 2 nd projecting portion 23 of the rear floor panel 2 described later.
The rear cross member 1 extends in the vehicle width direction and is bridged between a pair of left and right rear side members (not shown). The rear cross member 1 includes a cross member upper portion 11 and a cross member lower portion 12 having a hat-shaped cross section, and is configured to have a closed cross section by joining the cross member upper portion 11 and the cross member lower portion 12.
The rear floor 2 constitutes a part of the vehicle floor, and is connected with the rear side members and the rear cross member 1. Specifically, the rear floor 2 is provided between the beam upper portion 11 and the beam lower portion 12, and is joined to the beam upper portion 11 and the beam lower portion 12, respectively.
The rear floor 2 has a mounting portion 21 to which the jack mount 3 is mounted. The mounting portion 21 is disposed further toward the vehicle rear side than the rear cross member 1, and is adjacent to the rear cross member 1 in the vehicle length direction (Y1 and Y2 directions).
Specifically, the mounting portion 21 has a 1 st portion 21a, a 2 nd portion 21b, a 3 rd portion 21c, and a 4 th portion 21d arranged in this order from the rear to the front (toward the Y1 direction side).
The 1 st portion 21a is located at an end portion of the mounting portion 21 on the vehicle rear side, and extends in the horizontal direction. The 2 nd portion 21b extends upward from the front end of the 1 st portion 21a while extending toward the vehicle front side. The 2 nd portion 21b is curved in a shape bulging obliquely downward as viewed in the vehicle width direction. The 3 rd portion 21c extends upward from the front end (upper end) of the 2 nd portion 21b while extending toward the vehicle front side. The 3 rd portion 21c has an inclined linear shape as viewed in the vehicle width direction. The 4 th portion 21d extends horizontally from the front end (upper end) of the 3 rd portion 21c toward the vehicle front side and is connected to the rear cross member 1. That is, the 4 th portion 21d is located at the end of the mounting portion 21 on the vehicle front side.
Therefore, in the mounting portion 21, the 4 th portion 21d on the vehicle front side is positioned further upward than the 1 st portion 21a on the vehicle rear side, and the 2 nd portion 21b and the 3 rd portion 21c therebetween are disposed obliquely in the vehicle length direction.
The jack mount 3 is a member that comes into contact with a jack (not shown) when the jack is lifted. The jack stand 3 is located below the rear cross member 1 and the rear floor 2 and is mounted on the rear cross member 1 and the rear floor 2.
The jack mount 3 is, for example, box-shaped and arranged at a substantially middle position in the vehicle width direction. An abutting portion 31 for abutting against the jack is formed at the lower end portion of the jack mount 3. A connecting flange 32 is formed around the upper end of the jack stand 3 so as to be outwardly turned. The connecting flange 32 includes, for example, a front flange 32a, a rear flange 32b, a left flange (not shown), and a right flange (not shown). The front side flange portion 32a is joined to the lower surface of the rear cross member 1. The rear flange portion 32b, the left flange portion, and the right flange portion are engaged with the mounting portion 21 of the rear floor panel 2.
Fig. 2 is a bottom view showing the mounting portion 21 of the rear floor panel 2 and its surrounding portion in the vehicle lower portion structure 100. In the present embodiment, as shown in fig. 2, the mounting portion 21 is formed with the 1 st projection 22 and the 2 nd projection 23. The 1 st projection 22 and the 2 nd projection 23 are provided to improve the strength of the mounting portion 21. The 1 st projection 22 and the 2 nd projection 23 are formed to project upward from the mounting portion 21.
The 1 st projection 22 is formed to extend in a direction perpendicular to the vehicle width direction and to extend in the vehicle length direction when viewed from above. And, the 1 st projection 22 is provided on the 1 st and 2 nd parts 21a and 21b of the mounting part 21. The 1 st projecting portion 22 is disposed between the left and right flange portions of the jack mount 3 in the vehicle width direction.
The 2 nd projection 23 is formed to extend outward (left and right sides) in the vehicle width direction (X direction) from an end portion of the 1 st projection 22 on the vehicle rear side. And, the 2 nd projecting portion 23 is provided on the 1 st part 21a of the mounting portion 21.
Has the advantages that:
in the present embodiment, since the strength of the mounting portion 21 can be increased by forming the 1 st projection 22 and the 2 nd projection 23 on the mounting portion 21 as described above, the mounting portion 21 can be prevented from being deformed even when a load is applied to the mounting portion 21 during the lifting. Further, by using the 1 st projection 22 and the 2 nd projection 23 to increase the strength of the mounting portion 21, it is possible to suppress an increase in the vehicle body weight and the manufacturing cost as compared with increasing the thickness of the rear floor or adding a reinforcing member.
Therefore, according to the vehicle lower section structure 100 of the present embodiment, the deformation of the mounting section 21 during the jacking can be prevented while suppressing the increase in the vehicle body weight and the manufacturing cost.
The above embodiments are merely examples of the aspects of the present invention, and do not constitute a basis for limiting the explanation. Therefore, the technical scope of the present invention is not to be interpreted only by the description of the above embodiments, but is defined by the description of the claims of the present invention. The technical scope of the present invention includes all modifications equivalent to the scope of the claims of the present invention.
