Description

Bumper skirt

This disclosure relates to a bumper cart for vehicles with frames.

Patent Document 1 describes a front bumper structure composed of a bumper body, a front spoiler, and an engine undercover. The front spoiler is held at the lower end of the bumper body, the front end of the engine undercover is fixed to the front spoiler, and the rear end of the engine undercover is held by the front cross member.

Japanese Patent Application Laid-Open No. 2001-146140

In a framed vehicle in which the body of the cab or the like is supported by the frame via a mounting mechanism such as rubber, the body side and the frame side move relative to each other when the vehicle is running. Therefore, as in Patent Document 1, the bumper cart (front spoiler) is held at the lower end of the bumper (bumper body), the front end of the skid plate (engine undercover) is fixed to the bumper cart, and the rear end of the skid plate is on the frame side. When holding to (front cross member), it is necessary to support the bumper not on the body side but on the frame side.

However, when the bumper is supported on the frame side, it is necessary to provide a gap between the upper edge of the bumper and the body side in order to prevent interference, and such a gap impairs the appearance. In addition, the bumper of a vehicle with a frame may be supported not on the frame side but on the body side because it causes an increase in air resistance during running and a wind noise, and a bumper structure as in Patent Document 1 is used. Cannot be applied.

Therefore, the present disclosure can be suitably used for a vehicle with a frame in which the bumper is supported on the body side and a skid plate covering the engine from below is supported on the frame side behind the center of the bumper in the vehicle width direction. The purpose is to provide a skirt.

In order to achieve the above object, in the present disclosure, the body is supported by the frame via a mounting mechanism, the bumper extending in the vehicle width direction at the lower part of the front end of the vehicle is supported on the body side, and the rear of the center of the bumper in the vehicle width direction. It is a bumper cart of a vehicle with a frame in which a skid plate that covers the engine from below is supported on the frame side, and has a central skirt and left and right side skirts.

The central skirt is placed below the skid plate and is fixed to the skid plate without being supported by the body side. The left and right side skirts are arranged on the left and right sides of the center skirt, and are fixed to the bumper without being supported by the frame side. The center skirt and the left and right side skirts are lined up in the width direction behind the bumper. The front end of the central skirt is separated from the bumper.

In the above configuration, the bumper cart is divided into a central skirt in the center of the vehicle width direction and left and right side skirts (three divisions), the central skirt is fixed to the skid plate on the frame side, and the left and right side skirts are on the body side. Since it is fixed to the bumper, the center skirt and the left and right side skirts move relatively when the body side and the frame side move relative to each other when the vehicle is running. Further, since the front end portion of the central skirt is separated from the bumper, interference between the central skirt and the bumper can be avoided. That is, the skid plate can be provided below the rear of the bumper without causing interference due to relative movement between the body side and the frame side.

Since the bumper cart is provided below the rear of the bumper, the running wind that flows from the front to the lower part of the vehicle can be smoothly distributed to the rear by the bumper cart, and the running resistance (air resistance during running) is reduced. It is possible to improve fuel efficiency.

There is a gap between the front end of the center skirt and the bumper, but since the gap is provided only in the center, not the entire width direction, a single bumper cart extending over the entire width direction is placed on the frame side. Compared to the case of supporting the vehicle (when a gap is provided in the entire width direction of the vehicle), the appearance of the vehicle is less likely to be impaired, and an increase in air resistance during traveling and the generation of wind noise can be suppressed.

Also, when the above single bumper cart is fixed to the skid plate on the frame side, it is difficult to stabilize the support state because the bumper cart extends long outward in the vehicle width direction on the left and right sides of the skid plate. On the other hand, in the above configuration, since the left and right side skirts of the skid plate are supported on the body side, the front part of the side skirt is fixed to the bumper, and the rear part is fixed to another member on the body side (for example, an inner liner on the body side). ), The support state can be stabilized.

The bumper cart of the present disclosure can be suitably used for a vehicle with a frame in which the bumper is supported on the body side and a skid plate covering the engine from below is supported on the frame side behind the center in the vehicle width direction of the bumper.

FIG. 1 is a side view of a vehicle to which a bumper cart according to an embodiment of the present disclosure is attached. FIG. 2 is a front view of the bumper and bumper cart of FIG. 1 as viewed from the front. FIG. 3 is a perspective view of the bumper cart of FIG. FIG. 4 is a cross-sectional view taken along the line IV-IV of FIG. FIG. 5 is a sectional view taken along line VV of FIG.

Hereinafter, the first embodiment of the present disclosure will be described with reference to the drawings. In the present embodiment, the pickup truck is illustrated as the vehicle with a frame 1, but the vehicle with a frame is not limited to the pickup truck. In the figure, FR indicates the front of the vehicle, UP in the figure indicates the upper side of the vehicle, and IN in the figure indicates the inside in the vehicle width direction. Further, the front-rear direction in the following description means the front-rear direction of the vehicle, and the left-right direction means the left-right direction in a state of facing the front of the vehicle.

As shown in FIG. 1, in a vehicle 1 with a frame, a body 2 such as a cab is elastically supported by a frame (body frame) 3 via a mount mechanism (not shown), and when the vehicle is running, the body 2 side and the frame 3 side Moves relative to each other. The frame 3 has side members 3A extending in the front-rear direction on both left and right sides in the vehicle width direction, and cross members 3B (see FIG. 4) extending in the vehicle width direction and connecting the left and right side members 3A. A bumper (front bumper) 4 extending in the vehicle width direction is provided at the lower part of the front end of the vehicle 1. The bumper 4 is fixed to the body 2 side.

As shown in FIGS. 2 and 4, a skid plate 5 that covers the engine (not shown) from below is provided behind the center of the bumper 4 in the vehicle width direction. A hat-shaped lower bracket 6 is fixed to the upper surface of the skid plate 5, a vertical plate portion of the L-shaped upper bracket 7 is fastened and fixed to the front surface of the cross member 3B by bolts and nuts 8, and the lower bracket 6 is fixed to the upper bracket. It is fastened and fixed to the horizontal plate portion of No. 7 by bolts and nuts 9. In this way, the skid plate 5 is fixed to the frame 3 side.

As shown in FIGS. 2 and 3, a bumper cart 10 is provided diagonally below the rear of the bumper 4 and below the skid plate 5 over substantially the entire width direction of the vehicle. The bumper cart 10 is divided into three parts, a central skirt 11 and left and right side skirts 12. The central skirt 11 and the left and right side skirts 12 are arranged in the vehicle width direction below the rear of the bumper 4.

The central skirt 11 is arranged to face the lower surface of the skid plate 5. As shown in FIG. 4, a hat-shaped central skirt attachment portion 13 is formed so as to protrude from the upper surface of the central skirt 11, and the central skirt attachment portion 13 is fastened and fixed to the lower surface of the skid plate 5 by bolts and nuts 14. That is, the central skirt 11 is not supported on the body 2 side and is fixed to the skid plate 5. In such a state, the front end portion of the central skirt 11 is separated rearward from the rear end portion (lower end portion) of the bumper 4.

As shown in FIGS. 2 and 3, the left and right side skirts 12 are arranged on the left and right sides of the central skirt 11. As shown in FIG. 5, a hat-shaped side skirt front mounting portion 15 is formed so as to protrude from the upper surface of the front portion of the side skirt 12, and the side skirt front mounting portion 15 is fastened to the lower surface of the bumper 4 by bolts and nuts 16. It is fixed. Further, a side skirt rear mounting portion 17 extending upward and bending backward is integrally formed at the rear end portion of the side skirt 12, and the side skirt rear mounting portion 17 is formed on the lower surface of the inner liner 18 on the body 2 side. It is fastened and fixed by bolts and nuts 19. That is, the side skirt 12 is not supported by the frame 3 side and is fixed to the bumper 4.

According to the present embodiment, the bumper cart 10 is divided into a central skirt 11 in the center in the vehicle width direction and left and right side skirts 12 (three divisions), and the central skirt 11 is fixed to the skid plate 5 on the frame 3 side. Since the left and right side skirts 12 are fixed to the bumper 4 and the inner liner 18 on the body 2 side, the center skirt 11 and the left and right side skirts 12 when the body 2 side and the frame 3 side move relative to each other when the vehicle is running or the like. And move relatively. Further, since the front end portion of the central skirt 11 is separated from the bumper 4, interference between the central skirt 11 and the bumper 4 can be avoided. That is, the skid plate 5 can be provided below the rear of the bumper 4 without causing interference due to relative movement between the body 2 side and the frame 3 side.

Since the bumper cart 10 is provided below the rear of the bumper 4, the running wind flowing from the front to the lower part of the vehicle 1 can be smoothly circulated to the rear by the bumper cart 10 when the vehicle is running, and the running resistance (air during running) can be smoothly distributed. Resistance) can be reduced to improve fuel efficiency.

A gap is provided between the front end of the central skirt 11 and the bumper 4, but since the gap is provided only in the center, not in the entire width direction, a single bumper cart extending over the entire width direction is provided. Compared to the case of supporting on the frame 3 side (when a gap is provided in the entire width direction of the vehicle), the appearance is less likely to be spoiled, and the increase in air resistance and the generation of wind noise during running are suppressed. Can be done.

Further, when the single bumper cart is fixed to the skid plate 5 on the frame 3 side, it is difficult to stabilize the support state because the bumper cart extends long outward in the vehicle width direction on the left and right sides of the skid plate 5. On the other hand, in the present embodiment, the left and right side skirts 12 of the skid plate 5 are supported on the body 2 side, the front portion of the side skirt 12 is fixed to the bumper 4, and the rear portion is fixed to the inner liner 18.
