Japanese Unexamined Patent Publication No. 2012-171390

In the rear underrun protector (underlamp protector) of Patent Document 1, the cross-sectional shape of the vehicle body approaching side protector piece (protector inner) and the cross-sectional shape of the vehicle body separating side protector piece (protector outer) are different. For this reason, two types of long members having different cross-sectional shapes are required, which causes complicated parts management and the like.

Therefore, an object of the present invention is to provide an underrun protector capable of simplifying parts management.

In order to achieve the above object, the first aspect of the present invention is an underlamp protector which is arranged below one end of the front side and the rear side of the vehicle body, is fixed to the vehicle body side and extends in the vehicle width direction. A protector inner extending in the vehicle width direction and a protector outer extending in the vehicle width direction on one side of the protector inner and forming a closed cross section with the protector inner are provided.

The protector inner and the protector outer are composed of one and the other of two long members having the same cross-sectional shape. In the long member, the second plate portion and the third plate portion are bent and face each other from both end edges along the longitudinal direction of the first plate portion, and the third plate portion is the third plate portion than the second plate portion. It is formed in a J-shaped cross section that extends long from one plate.

The first plate portion of the protector inner and the first plate portion of the protector outer face each other in an upright state in which the longitudinal direction thereof is along the vehicle width direction and are separated from each other in the front-rear direction. The second plate portion and the third plate portion of the protector inner extend from the first plate portion of the protector inner to one side of the above. The second plate portion and the third plate portion of the protector outer extend from the first plate portion of the protector outer to the other side of the front and the rear of the vehicle body. The second plate portion of the protector inner and the third plate portion of the protector outer are welded in a vertically overlapped state to form one of the upper plate portion and the lower plate portion of the underrun protector. The third plate portion of the protector inner and the second plate portion of the protector outer are welded in a vertically overlapped state to form the other of the upper plate portion and the lower plate portion of the underrun protector.

In the case of a front underlamp protector in which the underlamp protector is arranged below the front end of the vehicle body, the protector outer is arranged on the front side of the protector inner, and the second plate part and the third plate part of the protector inner are the first plate part of the protector inner. It extends forward from the plate portion, and the second plate portion and the third plate portion of the protector outer extend rearward from the first plate portion of the protector outer.

In the case of a rear underramp protector in which the underlamp protector is located below the rear end of the vehicle body, the protector outer is located behind the protector inner, and the second and third plates of the protector inner are of the protector inner. It extends rearward from the first plate portion, and the second plate portion and the third plate portion of the protector outer extend forward from the first plate portion of the protector outer.

In the above configuration, since the protector inner and the protector outer are composed of one and the other of two long members having the same cross-sectional shape, it is not necessary to manage a plurality of types of long members having different cross-sectional shapes, and the parts Management can be simplified.

Here, the long members having the same cross-sectional shape constituting the protector inner and the protector outer have the same length from both end edges of the first plate portion so that the second plate portion and the third plate portion have the same plate width. The second plate of the protector inner and the second plate of the protector outer are overlapped and welded to form the upper plate of the underrun protector (protector upper plate), and the protector inner is formed into a U-shaped cross section. By stacking the third plate part of the protector outer and the third plate part of the protector outer on top of each other and welding them to form the lower plate part of the underlamp protector (lower plate part of the protector), the rear underlamp protector (long member is U). It is also possible to form a protector with a cross section.

However, in the plate width direction of the protector upper plate portion, both sides of the portion excluding the overlapping range between the second plate portions from the total plate width of the protector upper plate portion are non-overlapping portions of the second plate portion, and thus are long. In the protector having a U-shaped cross section, the region of the second plate portion (single plate region) that does not overlap with each other is less than half the total plate width of the protector upper plate portion. The same applies to the lower plate portion of the underlamp protector, and the single plate region of the third plate portion is less than half the total plate width of the lower plate portion. For this reason, a cap is placed on the outer peripheral surface of the end portion of the underlamp protector in the vehicle width direction, and the single plate area of the protector upper plate portion and the single plate region of the protector lower plate portion are capped by a connecting member such as a tapping screw or a screw. When fixing the cap cylinder portion of the above, the range in the plate width direction of the protector upper plate portion and the protector lower plate portion that can be connected is limited by the connecting member, which may reduce workability or make fastening impossible.

On the other hand, in the above configuration, the length of the J-shaped cross section in which the third plate portion extends longer than the second plate portion from the first plate portion and the plate width of the third plate portion is wider than the plate width of the second plate portion. Since the second plate part and the third plate part are welded together to form the upper plate part (protector upper plate part) and the lower plate part (protector lower plate part) of the underrun protector using a scale member, the protector upper plate part. In each plate width direction of the portion and the protector lower plate portion, the non-overlapping portion (single plate region) of the third plate portion can be set to half or more of the total plate width of the protector upper plate portion and the protector lower plate portion. Therefore, when the cap is connected to the end portion of the underrun protector in the vehicle width direction by the coupling member, it is possible to secure a wide range in the plate width direction of the protector upper plate portion and the protector lower plate portion that can be connected by the coupling member. It is possible to improve workability and avoid inability to fasten.

The second aspect of the present invention is the underlamp protector of the first aspect, and the protector inner extends in the vehicle width direction in a posture in which the second plate portion is on the upper side and the third plate portion is on the lower side, and the protector is a protector. The outer extends in the vehicle width direction in a posture in which the third plate portion is on the upper side and the second plate portion is on the lower side.

In the above configuration, the second plate portion of the protector inner and the third plate portion of the protector outer are welded on top of each other on the upper plate portion of the underlamp protector, and the second plate portion of the protector inner is welded on the lower plate portion of the underlamp protector. The three plate portions and the second plate portion of the protector outer are welded on top of each other. That is, when comparing the welded portion of the upper plate portion and the welded portion of the lower plate portion, the front-rear position of the welded portion of the upper plate portion is closer to the center side (front) of the vehicle in the front-rear direction than the front-rear position of the welded portion of the lower plate portion. In the case of the under lamp protector, the welded part of the upper plate part is behind the welded part of the lower plate part, and in the case of the rear under lamp protector, the welded part of the upper plate part is closer to the welded part of the lower plate part. It is placed on the front side). Therefore, in the case of the front underlamp protector, the welded portion of the upper plate portion becomes difficult to see from the front upper part of the vehicle, and in the case of the rear underlamp protector, the welded portion of the upper plate portion becomes difficult to see from the rear upper part of the vehicle. The appearance is improved.

A third aspect of the present invention is the underlamp protector of the second aspect. In the upper plate portion of the underlamp protector, the third plate portion of the protector outer overlaps the second plate portion of the protector inner from above. In the lower plate portion of the underlamp protector, the third plate portion of the protector inner overlaps with the second plate portion of the protector outer from below.
In the above configuration, in the upper plate portion of the under lamp protector, the third plate portion of the protector outer is welded to the second plate portion of the protector inner from above, so that in the case of the front under lamp protector, the upper plate portion is welded. The welded part becomes more difficult to see from the front upper part of the vehicle, and in the case of the rear underrun lamp protector, the welded part of the upper plate part becomes more difficult to see from the rear upper part of the vehicle, and the appearance is further improved.

According to the underrun protector of the present invention, it is possible to simplify the parts management.

Using a long member 20 having a J-shaped cross section, the narrow plate portion 22 of the protector inner 11 and the wide plate portion 23 of the protector outer 12 are welded to form the protector upper plate portion 14, and the wide plate portion 23 of the protector inner 11 is formed. And the narrow plate portion 22 of the protector outer 12 are welded together to form the protector lower plate portion 15, so that the non-overlapping portion of the wide plate portion 23 is formed in each plate width direction of the protector upper plate portion 14 and the protector lower plate portion 15. (Single plate region) can be set to half or more of the total plate width of the protector upper plate portion 14 and the protector lower plate portion 15. Therefore, when the cap 40 is connected to the end portion of the RUP 10 in the vehicle width direction by a coupling member (tapping screws 43, 44), the protector upper plate portion 14 and the protector lower plate portion 15 that can be connected by the coupling member are connected in the plate width direction. It is possible to secure a wide range of the above, improve workability, and avoid inability to fasten.

Further, in the protector upper plate portion 14, the narrow plate portion 22 of the protector inner 11 and the wide plate portion 23 of the protector outer 12 are vertically overlapped and welded, and in the protector lower plate portion 15, the wide plate portion of the protector inner 11 is welded. 23 and the narrow plate portion 22 of the protector outer 12 are vertically overlapped and welded, and when the welded portion 25 of the protector upper plate portion 14 and the welded portion 26 of the protector lower plate portion 15 are compared, the protector upper plate portion 14 The welded portion 25 is arranged on the center side of the vehicle 1 in the front-rear direction (the welded portion 25 of the protector upper plate portion 14 is on the front side of the welded portion 26 of the protector lower plate portion 15) with respect to the welded portion 26 of the protector lower plate portion 15. NS. Further, in the protector upper plate portion 14, the wide plate portion 23 of the protector outer 12 is welded to the narrow plate portion 22 of the protector inner 11 from above. Therefore, the welded portion 25 of the protector upper plate portion 14 becomes difficult to see from the rear upper side (direction of the arrow 46 in FIG. 3) of the vehicle, and the appearance is good.
