Description
Technical Field
The utility model relates to a vehicle rear portion structure.
Background
Generally, a rear structure of a vehicle such as a station wagon or a minibus includes a D-pillar 50 and a gutter 60 as shown in fig. 3. The D-pillar 50 is configured by joining an inner member 51 and an outer reinforcement 52 to each other, and has a closed cross-section having four corners. The gutter channel 60 is provided on the side of the D-pillar 50 adjacent to the rear door opening 53.
Specifically, the inner member 51 and the outer reinforcement 52 are each bent into a bent plate shape, that is, a groove-shaped cross section, and each has two plate portions inclined in different directions. The end piece 51c of the back-inclined plate portion 51a of the inner member 51, the end piece 52c of the back-inclined plate portion 52a of the outer reinforcement 52, and the end piece 61 inside the gutter 60 are overlapped and joined together. The end pieces 51d of the front plate portions 51b of the inner member 51 and the end pieces 52d of the front plate portions 52b of the outer reinforcement 52 are overlapped and joined together. The joining between the members is performed by, for example, spot welding, and the like, and an "x" in fig. 3 shows a joining portion between the members.
In the above-described conventional structure, the inner member 51 and the outer reinforcement 52 are joined only at the outer portions of the two small corners of the closed cross section of the approximate diamond shape (the end piece 51c is joined to the end piece 52c, and the end piece 51d is joined to the end piece 52 d). Therefore, for example, when the vehicle body twists and the external force acts on the inner member 51 or the outer reinforcement 52, the closed cross-sectional structure of the D-pillar 50 is easily collapsed.
On the other hand, it is conceivable to increase the rigidity of the D-pillar 50 having a closed cross section by increasing the plate thickness of the inner member 51 and the outer reinforcement 52, but this increases the weight of the D-pillar 50.
SUMMERY OF THE UTILITY MODEL
In view of the above, an object of the present invention is to provide a vehicle rear structure that can improve the stability of the closed cross-section structure of a D-pillar and can avoid the weight increase of the D-pillar.
As a technical solution to solve the above technical problem, the present invention provides a vehicle rear structure, which includes a D-pillar and a gutter channel, the D-pillar is a member having four corners and a closed cross section, the member being formed by joining an inner member and an outer reinforcement, the gutter channel is provided on a side of the D-pillar adjacent to a rear door opening, the inner member and the outer reinforcement are bent into a bent plate shape, and each of the inner member and the outer reinforcement has a forward inclined plate portion and a backward inclined plate portion that are inclined in different directions, and the vehicle rear structure is characterized in that: the end edge piece of the front-inclined plate part of the inner component is overlapped and jointed with the end edge piece of the front-inclined plate part of the outer reinforcing part; the end edge piece of the backward inclined plate part of the inner member is overlapped and jointed with the end edge piece of the inner side of the water flowing groove; the rear inclined plate section of the inner member is positioned in the vicinity of the end piece joined to the water flow channel, and the end piece of the rear inclined plate section of the outer reinforcement is overlapped and joined together.
The utility model discloses an above-mentioned vehicle rear portion structure's advantage lies in, can improve the closed cross section structure's of D post steadiness, can avoid the weight gain of this D post again. Specifically, in comparison with the conventional structure shown in fig. 3, the joining portion between the backward inclined plate portion of the inner member and the backward inclined plate portion of the outer reinforcement is moved from the end pieces to each other to a portion of the backward inclined plate portion located in the vicinity of the end piece joined to the water flow channel. Therefore, the joint strength between the inner member, the outer reinforcement and the gutter is increased by changing the number of the joints at the D-pillar from two to three, and the closed cross-sectional structure of the D-pillar is more stable because the end piece of the outer reinforcement directly supports the rear inclined plate portion of the inner member rather than the end piece, so that the closed cross-sectional structure of the D-pillar is less likely to collapse when the inner member and the outer reinforcement are subjected to external force due to the twisting of the vehicle body. In addition, since the plate thicknesses of the inner member and the outer reinforcement do not need to be increased, the weight increase of the D-pillar can be avoided.
In addition, in the above vehicle rear structure of the present invention, preferably, the closed cross section of the D-pillar is a rhombus having two large corner portions and two small corner portions, and the two large corner portions are the bending portion of the inner member and the bending portion of the outer reinforcement, respectively.
Based on this structure, can further improve the steadiness of the closed cross section structure of D post, especially when receiving the external force effect in the big-angle part of at least one in medial component and outside reinforcement, the closed cross section structure of D post is difficult to the collapse.

Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Fig. 1 is a perspective view showing a vehicle rear structure according to the present embodiment, and fig. 2 is a cross-sectional view taken along the arrow of the line (2) - (2) in fig. 1.
As shown in fig. 1 and 2, a rear structure of a vehicle such as a station wagon or a minibus generally includes a D-pillar 1, a gutter 2, and the like.
The D-pillar 1 is a member having four corners and a closed cross section, which is formed by joining an inner member 11 and an outer reinforcement 12. The closed cross-section is a diamond-shaped cross-section having two large corners and two small corners. In the present embodiment, the large corner is an obtuse corner, and the small corner is an acute corner.
The D-pillars 1 are provided on the left and right sides of the rear door opening 3, but only one D-pillar 1 is shown in the present embodiment.
The gutter 2 is a groove portion provided on the periphery of the rear door opening 3. The gutter channel 2 is provided on the side of the D-pillar 1 adjacent to the rear door opening 3.
The inner member 11 and the outer reinforcement 12 are each bent into a bent plate shape and have two face plate portions inclined in different directions, that is, the inner member 11 has a backward inclined plate portion 11a and a forward inclined plate portion 11 b; the outer reinforcement 12 has a backward inclined plate portion 12a and a forward inclined plate portion 12b, and the inner member 11 and the outer reinforcement 12 are bent in a groove-like shape in cross section.
The bent portion where the rear inclined plate portion 11a of the inner member 11 and the front inclined plate portion 11b intersect and the bent portion where the rear inclined plate portion 12a of the outer reinforcement 12 and the front inclined plate portion 12b intersect each constitute the two large corner portions (obtuse corner portions).
The end edge pieces 11c of the backward inclined plate part 11a of the inner member 11 are overlapped and joined with the end edge pieces 2a inside the gutter 2; the end edge pieces 11d of the front plate portions 11b of the inner member 11 and the end edge pieces 12d of the front plate portions 12b of the outer reinforcement 12 are superposed and joined together; the rear inclined plate portion 11a of the inner member 11 is positioned near the end piece 11c joined to the water flow channel 2, and is joined to the end piece 12c of the rear inclined plate portion 12a of the outer reinforcement 12 by being superposed on it.
The joining of the members is performed by, for example, spot welding, and the like, and the "x" in fig. 2 shows the joining of the members.
Next, the operation and effect of the vehicle rear structure of the present embodiment will be described.
In the vehicle rear structure of the present embodiment, the inner member 11 and the outer reinforcement 12 are joined at two small corner portions of a closed cross section having a substantially rhombic shape, and the end edge piece 11c of the rear inclined plate portion 11a of the inner member 11 is joined to the end edge piece 2a of the gutter 2. Compared to the conventional structure shown in fig. 3, the joint portion between the backward inclined plate portion 11a of the inner member 11 and the backward inclined plate portion 12a of the outer reinforcement 12 is moved to a portion of the backward inclined plate portion 11a near the end piece 12c joined to the water flowing channel 2. Therefore, the welding joints at the D-pillar 1 are changed from two to three, so that the joint strength between the inner member 11, the outer reinforcement 12, and the water flow channel 2 is increased, and the end edge pieces 12c of the outer reinforcement 12 directly support the receding plate portion 11a of the inner member 11 instead of supporting the end edge pieces 11c, so that the stability of the closed cross-sectional structure of the D-pillar 1 is improved. Therefore, when the inner member 11 and the outer reinforcement 12 are subjected to an external force due to the twisting of the vehicle body, the closed cross-sectional structure of the D-pillar 1 is less likely to collapse, and particularly, when a large-angle portion of at least one of the inner member 11 and the outer reinforcement 12 is subjected to an external force, the closed cross-sectional structure of the D-pillar 1 is less likely to collapse.
Further, since it is not necessary to thicken the plate thicknesses of the inner member 11 and the outer reinforcement 12 as in the conventional technique, the weight of the D-pillar 1 does not increase.
