Description

The present invention relates to a front structure of a cab-over type vehicle.

b. Prior art FIGS. 7 to 9 show a front structure of a conventional cab-over type vehicle, in which a front panel 101 has left and right side edges 101a in a closed cross section by an inner panel 102 and an outer panel 103. The front end 104a of the formed front pillar 104
, And a lower edge 101b thereof is fixed to a front end portion 105a of the floor panel 105. And the front panel 101
An upper edge 106a of a window member 106 having a substantially U-shaped cross section is fixed to an inner surface of an upper edge 101c of the front member 101, and left and right side edges 106b of the window member 106 are fixed to an inner panel 102 of the front pillar 104 via a bracket 107. Have been. In addition,
In the figure, reference numeral 108 denotes a front bumper disposed in front of and below the front panel 101, 109 denotes a chassis frame extending in the front-rear direction of the vehicle body, 110 denotes a weather strip 111 above the front panel 101 reinforced by the wind member 106. It is a window glass attached.

c. Problems to be Solved by the Invention However, in the above-described front structure of the cab-over type vehicle, since the front panel 101 is a single outer plate, the front panel 101 has a lower edge of the wind member 106.
When 106b was welded, it could not be carried out because the appearance after welding appeared, and it was fixed at best with a mounting agent. Therefore, there is a problem that the strength near the lower portion of the window glass 110 is irregular.

In addition, since the front panel 101 is a single panel, there is also a disadvantage that the wind noise and the transmitted sound are large at the time of high-speed running, and the temperature of the vehicle interior in a cold region is lowered.

Further, since it is necessary to install a steering shaft, a pedal, a heater, an air conditioner, and the like on the indoor side of the front panel 101, the shape of the front panel 101 cannot be freely changed, and the design of the front part of the vehicle body is free. There was also a problem that the degree was low.

The present invention has been made in view of the problems of the above-described conventional front structure of a cab-over type vehicle.

d. Means for Solving the Problems In order to solve the above-mentioned problems, the present invention is to form an inner panel that constitutes front pillars that are present on both left and right sides of a vehicle body, on both right and left sides of the front panel. The upper and lower edges of a substantially U-shaped cross section of a wind member extending in the vehicle width direction are fixed to the upper front surface of the vehicle, and the left and right edges of the wind member are fixed to the front pillar. The cab-over type vehicle has a front structure in which the upper end of an exterior panel covering the front of the front panel is fixed, and the lower end is fixed to the front panel at least below the upper end of the front bumper.

e. Function In the front structure of the cab-over type vehicle according to the present invention, the inner panel constituting the front pillar is formed on the left and right sides of the front panel as described above, so that the number of parts can be reduced and the waterproof property can be improved. The number of joints between panels, which causes problems, is reduced, and both the assembling property and the waterproofness are improved.

In addition, the substantially U-shaped window member provided on the upper front surface of the front panel has a completely closed cross section with the upper and lower edges and the left and right edges fixed to the front panel and front pillar, respectively, improving rigidity. Then, the strength near the lower portion of the window glass becomes sufficient.

Furthermore, in the present invention, the upper end of the exterior panel covering the front of the front panel is fixed to the front of the wind member, and the lower end is fixed to the front panel at least below the upper end of the front bumper.
By changing the shape of the exterior panel, the exterior shape of the vehicle body can be freely designed, and since the front portion of the vehicle body has a dual structure of the front panel and the exterior panel, wind noise and transmitted sound can be reduced. It is possible to prevent the reduction and the decrease in the room temperature in a cold region.

f. Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings and FIGS.

Here, FIG. 1 shows a cab-over type vehicle 1, in which 2 is a front part of a vehicle body, 3 is a front pillar, 4 is a window glass, and 5 is a front bumper.

The above-described vehicle body front part 2 is configured by attaching an external panel 7 to the outside (front side) of the front panel 6 as shown in FIG.

The left and right sides 6a of the front panel 6 are AA in FIG.
As shown in FIGS. 4 and 5 which are end views along the line and the line BB, the front pillar 3 is bent backward.
Of the inner panel 8. Front pillar 3
Is formed in a closed cross section by welding an outer panel 9 as a separate member to an inner panel 8 constituted by the front panel 6. However, as shown in FIG. 4, the outer panel 9 at the position where the later-described window member 10 is joined is not welded to the inner panel 8 as shown by the imaginary line (two-dot chain line), but is shown by a solid line. As described above, it extends in the vehicle width direction and forms a flange portion 11 for joining the wind member 10.

Below the position where the wind member 10 is joined to the front pillar 3, there is formed an extension 12 protruding forward as shown in FIGS. 3 and 5, the extension 12 comprising an inner panel 13 and an outer panel. The front pillar 3 is reinforced by fixing a member having a substantially U-shaped cross section formed by joining the panels 14 in front of the front pillar 3.

As shown in FIG. 6, the wind member 10 has upper and lower edges 10a, 10b fixed to the upper front surface of the front panel 6 by welding, and left and right edges 10c of the flange portion formed on the front pillar 3. By being welded and fixed to 11, it is formed in a completely closed cross section, and the rigidity near the lower portion of the window glass 4 is secured.

The exterior panel 7 has an upper edge 7a welded and fixed below the wind member 10, and a lower edge 7b is attached to the front plate surface of the front panel 6 behind the upper end of the front bumper 5 as shown in FIG. It is welded and fixed to the tip of the fixed holder 15. The left and right side edges 7c of the exterior panel 7 are welded and fixed to the front end of an extension 12 formed in front of the front pillar 3, as shown in FIG.
This fixed portion is covered with a fender panel 16.

The window glass 4 is fixed above the front panel 6 reinforced by the window member 10 via an adhesive 17, and a garnish 18 also serving as a molding for preventing the adhesive 17 from flowing out is shown in FIG. As described above, the front panel 7 is fixed to the front surface of the window member 10 by the clip 19 so as to cover the connection portion of the upper edge 7a of the exterior panel 7.

As described above, one embodiment of the front structure of the cab-over type vehicle according to the present invention has been described. However, the present invention is not limited to the above-described embodiment, and various modifications may be made based on the technical idea of the present invention. Can be modified and changed.

For example, in the above embodiment, the extension 12 projecting forward of the front pillar 3 is formed, and the left and right side edges 7c of the exterior panel 7 are fixed to the extension 12, but the extension 12 is not necessarily required. It is not necessary, and the right and left side edges 7c of the exterior panel 7 may be directly fixed to the front pillar 3. Also, the front pillar 3 via the fender panel 16
It is good also as a structure fixed to. However, with the structure as in the embodiment, the rigidity of the exterior panel 7 is sufficient, and the strength of the front portion of the vehicle body against impact is improved.

g. Effect of the Invention The front structure of the cab-over type vehicle according to the present invention has the inner panel forming the front pillar integrally formed by the left and right sides of the front panel as described above. It is possible to provide a front structure of a cab-over type vehicle, which can be achieved, reduces the number of joints of panels where water resistance is a problem, and has good assemblability and waterproofness.

Further, since the wind member provided on the upper front surface of the front panel has a completely closed cross section, its rigidity is improved, and the strength near the lower portion of the window glass is sufficient.

Further, in the present invention, since the exterior panel covering the front panel is provided, the exterior shape of the vehicle body can be freely designed by changing the shape of the exterior panel, and further, wind noise and transmitted sound can be reduced. In addition, it is possible to prevent a decrease in room temperature in a cold region.
