Description

This invention relates to a bonnet to be mounted on a cab-over type vehicle, which is mainly composed of panels made of ABS resin.

The cab-over type one-box vehicle is easy to handle during driving and has a large interior space compared to the size of the vehicle body, so it is often used as a commercial vehicle suitable for the road conditions in Japan. there is In such a one-box vehicle, as shown in FIG. 7, the standard bonnet _H2 of the current mainstream vehicle is pressed obliquely forward from the lower end of the front window 51 downward by pressing a steel plate. It has a shape of protruding, extending while curving in the vertical direction, and reaching the front grille 52 .

In addition, as a custom part for the car model, a bonnet made of FRP (fiber reinforced plastic) is provided that protrudes forward more than the standard bonnet _H2 and the lower end covers the upper part of the front grille. The FRP bonnet is lighter than the standard bonnet _H2 , and is designed to express individuality.

Although it is not specialized for cab-over type vehicles, the following Patent Document 1, 2 are known.

Conventionally, FRP bonnets as custom parts are manufactured manually by a process such as molding a sheet material and then polishing it. An attempt was made to develop a product molded from ABS resin with a mold, which has the same advantages as that of the original product.

However, in the case of a cab-over type vehicle, the engine is located under the driver's seat and front passenger's seat, and not under the hood, but if the vehicle is idle for a long time, the radiator located behind the front grill It has been found that heat causes thermal deformation in prototypes made of ABS resin.

Accordingly, the object of this invention is to prevent thermal deformation without impairing the advantages of an ABS resin bonnet mounted on a cab-over type vehicle.

In order to solve the above problems, this device is mounted on a cab-over type vehicle, projects obliquely forward from the lower end of the front window downward, extends while curving in the vertical direction, and the lower end is In the bonnet that covers the upper part of the front grill,
Consists of a hood body that forms an outer panel made of ABS resin, and a heat shield material attached to the back surface of the hood body,
The heat shield material is positioned below the hood body above the radiator and extends in a belt shape in the vehicle width direction.

Further, the heat shield material has a large vertical width at the intermediate portion in the vehicle width direction, and has a narrow vertical width at both side portions in the vehicle width direction toward the ends.

In addition, the heat shield material has a laminated structure composed of a fabric core made of polyethylene fabric, a polyethylene laminate sheet laminated on both sides thereof, and an aluminum foil covering the surface of each of the laminate sheets. I made it.

In the ABS bonnet according to this invention, since the foot body is made of ABS resin, it is possible to mass-produce lightweight and well-designed bonnets by molds, and to provide consumers with products of stable quality at relatively low prices. can be done.

The heat shielding material is attached to the lower part of the back of the hood body above the radiator and extends in the width direction of the vehicle in a strip shape. Even if the vehicle is parked for a long time, thermal deformation of the hood body due to heat from the radiator is prevented.

Embodiments of this invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, this ABS bonnet _H1 is mounted on a cab-over type one-box vehicle, and is attached to a hood body 1 that constitutes an outer panel made of ABS resin and its back surface. It consists of a heat shield material 2.

The hood body 1 protrudes obliquely forward from the lower end of the front window 51 and extends downward while curving in the vertical direction to reach the front grille 52 . In the hood body 1, a forward portion 11 is positioned in the middle portion in the vehicle width direction and a forward portion 11 is formed.

The lower end of the front portion 11 of the hood body 1 covers the upper portion of the front grille 52 , and the lower edge of the side portion 12 is inclined upward from the lower edge of the front portion 11 sideways.

A space near the front window 51 below the ABS bonnet _H1 is provided with tanks for brake fluid, coolant, and window washer fluid, etc. A radiator 53 is provided in a space behind the front grille 52 . These spaces are separated by partition walls 54 .

As shown in FIGS. 3 and 4, the back side of the hood body 1 has a plurality of recesses 13 for thinning without affecting the front side, and a plurality of vertically extending ribs for ensuring strength. 14 are arranged side by side. Further, a flat fitting portion 15 extending in the left-right direction is formed with a locking striker 55 attached to the widthwise central portion of the lower portion sandwiched therebetween.

The shape of the upper portion of the fitting portion 15 corresponds to the shape of the sealing portion at the upper end of the partition wall 54 shown in FIG. In order to avoid striker 55 of hood body 1 , heat shielding material 2 is divided into left and right at the center in the vehicle width direction, and left and right heat shielding materials 2 are fitted into fitting portions 15 of hood body 1 respectively.

As shown in FIGS. 4 and 5, the left and right heat shields 2 each extend in a belt shape in the vehicle width direction from the middle lower portion of the front portion 11 of the hood body 1 to the lower portion of the lateral portion 12 . The width in the vertical direction is wide at the intermediate portion in the vehicle width direction, and the width in the vertical direction at both side portions in the vehicle width direction is narrowed toward the end portions.

The reason why the heat shielding material 2 has such a shape is that the middle portion in the vehicle width direction is more affected by the heat from the radiator 53 than the both side portions. Further, the heat shielding material 2 is formed with holes and cutouts for avoiding projections on the rear surface of the hood body 1 and the like.

As shown in FIG. 6, the heat shielding material 2 consists of a fabric core 21 made of polyethylene fabric, a polyethylene laminate sheet 22 laminated on both sides of the core material 21, and an aluminum foil covering the surface of each laminate sheet 22. 23 is a laminated structure. The overall thickness of the heat shield 2 is about 5 mm.

A double-sided adhesive tape is adhered to the rear surface of the heat shielding material 2 , and the release paper is peeled off, and the heat shielding material 2 is adhered to the fitting portion 15 on the rear surface of the hood body 1 .

Since the hood body ₁ of the ABS bonnet H1 as described above is made of ABS resin, it is possible to mass-produce lightweight and well-designed products using molds, and to provide products of stable quality to consumers at relatively low prices. can provide.

As shown in FIG. 1, the heat shielding material 2 is attached to the lower part of the back surface of the hood body 1 above the radiator 53 and extends in the width direction of the vehicle in a strip shape, so that the cab-over type wagon can be installed. , the heat from the radiator 53 is blocked by the heat shielding material 2, making it difficult for the heat from the radiator 53 to be transmitted to the hood body 1 even if the vehicle is stopped for a long time with the engine idling due to traffic jams or the like, causing thermal deformation of the hood body 1. is prevented.

In the above embodiment, the case where the ABS bonnet H ₁ is attached to a cab-over type one-box vehicle was exemplified, but the ABS bonnet H ₁ according to the present invention can be installed on the roof of the cargo bed if it is a cab-over type vehicle. It can also be installed on van-body trucks with flat bodies or box-type beds.
