[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front body structure of an automobile, and more particularly, to a structure for improving the rigidity of a cab mount of an automobile in which a vehicle body is bolted to a frame.

[0002]

[Prior art]

 As disclosed in Japanese Patent Publication No. 54-42487, there is known a vehicle body structure in which a vehicle body is bolted to a frame. This type of vehicle has a monocoque structure as compared with a monocoque structure. It is called a full frame structure.

In an automobile having a full-frame structure, cab mounts are provided at a plurality of positions on the vehicle body, and bolts are fastened to the frame through the cab mounts. High rigidity is required for the cab mount.

[0004]

[Problems to be solved by the device]

 That is, in the cab mount located at the center of the vehicle body, it is possible to disperse the vibrations transmitted from the frame in four directions, but in the cab mount located at the front end of the vehicle body, the vibrations transmitted from the frame are dispersed. At least it is impossible to spread forward.

Therefore, an object of the present invention is to provide a front vehicle body structure for an automobile, in which the rigidity of a cab mount located at the front end of the vehicle body is improved on the premise of an automobile having a full frame structure.

[0006]

[Means for Solving the Problems]

 In order to achieve such a technical problem, according to the present invention, in a vehicle in which a vehicle body is bolted to a frame, the mounting portion of the vehicle body is provided at the front end of the vehicle body and is attached to the frame. A cab mount that constitutes a bottom plate part having an insertion hole for the fastening bolt, an inner standing part extending upward from an inner end of the bottom plate part in the vehicle width direction, and an outer part of the bottom plate part in the vehicle width direction. An outer upright portion extending upward from an end, and the inner upright portion is connected to the shroud upper via a first reinforcement extending in the up and down direction. The first reinforcement and the second reinforcement are connected to a connecting portion between the shroud upper and the wheel apron via a second reinforcement that extends, and the shroud is provided between the first reinforcement and the second reinforcement. Headlight mounting opening formed in the side panel is a configuration in which is located.

[0007]

[Action]

 According to the above configuration, the vibration transmitted from the frame to the cab mount provided at the front end of the vehicle body is dispersed to the shroud upper through the first reinforcement and the wheel through the second reinforcement. It will be dispersed at the joint between the rue apron and the shroud upper.

[0008]

【Example】

 Embodiments of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 is a shroud panel, and the shroud panel 1 includes a shroud upper 2 extending in the vehicle width direction at a front end of a vehicle body, and shroud side panels 3 arranged on both left and right sides of the shroud upper 2. The shroud side panel 3 has an opening 3a for mounting a headlight in its upper part. Further, the lower portion of the shroud side panel 3 has a shape in which an outer side portion thereof is cut out, and the cutout portion 3b serves as an installation space A for an oil crawler (not shown) for an automatic transmission.

A first cross member 4 extending in the vehicle width direction is joined to a front surface of a lower end of the shroud side panel 3, and a space narrowed by the first cross member 4 and the shroud upper 2 is included. The center of the shroud side panel 3 in the vehicle width direction is a radiator installation space B, as is known.

In FIGS. 1 and 2, reference numeral 6 is a cab mount. The cab mount 6 has an L shape as a whole as shown in the figure, and a bolt insertion hole 8 is formed in the bottom plate portion 7 thereof, and the bolt inserted into the bolt insertion hole 8 as shown in FIG. The frame 9 is fixed to a frame 10 extending in the front-rear direction of the vehicle body.

The cab mount 6 includes an inner upright portion 11 extending upward from an inner end in the vehicle width direction of the bottom plate portion 7, and an outer upright portion extending upward from an outer end in the vehicle width direction of the bottom plate portion 7. And a first flange 12a extending in the up-down direction is formed at the rear edge of the outer upright portion 12. Further, the cab mount 6 has a second flange 13 that extends along the front end edge thereof and has an L shape as a whole, while the lower portion of the inner upright portion 11 is notched forward. The cutout portion 11a is formed, and the third flange 14 is formed along the edge of the cutout portion 11a.

The cab mount 6 is attached to the first cross member 4 and the shroud side panel 3 from the front side thereof, and the bottom plate portion 7 is provided under the first cross member 4 and the notch of the inner upright portion 11 is formed. The portion 11a is fitted into the first cross member 4, the outer upright portion 12 is positioned outside the end face of the first cross member 4, and the first flange 12a is placed in contact with the front surface of the shroud side panel 3. It

The first flange 12 a is joined to the shroud side panel 3, and the lower portion of the third flange 14 is joined to the first cross member 4.

The inner standing portion 11 is connected to the shroud upper 2 via a first reinforcement 20 extending in the vertical direction. That is, the first reinforcement 20 is basically composed of a plate member having a width in the front-rear direction of the vehicle body, and a flange 20b extending in the vertical direction is formed at a front end edge of a wall portion 20a of the plate member. The lower end of the flange 20b is joined to the first cross member 4 and the upper end thereof is joined to the shroud upper 2. The inner upright portion 11 is joined to the wall portion 20a of the first reinforcement 20 coupled to the shroud upper 2 and the first cross member 4 in this manner.

On the other hand, the outer upright portion 12 is joined to a front flange 22 a formed on the front end edge of the wheel apron 22, and the front flange 22 a extends vertically along the front end edge of the wheel apron 22. ing. Of course, an upper flange 22b extending in the front-rear direction is formed on the upper edge of the wheel apron 22, and the front end of the upper flange 22b is joined to the end of the shroud upper 2. In the figure, the X mark means welding.

With the above configuration, the vibration transmitted from the frame 10 to the cab mount 6 is transmitted to the shroud upper 2 via the inner upright portion 11 and the first reinforcement 20. Further, it is transmitted from the outer upright portion 12 to the connecting portion between the wheel apron 22 and the shroud upper 2 via the front flange 22a as the second reinforcement.

[0017]

[Effect of the device]

 As is apparent from the above description, according to the present invention, the inner upright portion of the cab mount is connected to the shroud upper via the first reinforcement, and the outer upright portion is connected through the second reinforcement. Since it is connected to the joint between the shroud upper and the wheel apron, it is possible to disperse the vibrations transmitted from the frame to these members, thus increasing the rigidity of the cab mount located at the front end of the vehicle body. Can be improved.
