[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combined structure of a back panel and a quarter pillar at a rear portion of a cab in a vehicle such as a pickup truck in which a cab and a luggage compartment are separately provided.

[0002]

2. Description of the Related Art Generally, a vehicle such as a pickup type truck in which a driver's cab and a luggage compartment are separately provided independently is shown in FIG.
As shown in FIG. 6, the operator's cab 1 welds parts such as a dash panel part 2, a roof panel 3, a side member 4, a floor panel 5, and a back panel 6 formed by pressing a rolled steel plate by an automatic assembly line or the like. It has a box-shaped skeletal structure.

[0003] Like the quarter pillars 10 provided on the rear left and right sides of the operator's cab 1, a portion requiring particularly high strength and rigidity, and a back panel 6 at the lower side of the window frame portion of the back window. As shown in FIGS. 7 and 8, a reinforcement 7 formed in a hat-shaped cross- section is joined to the inner side surface in a closed cross-section structure . The quarter pillar 10 has a closed cross-sectional structure including a quarter outer panel 8a and a quarter inner panel 8b. The left and right edges 6a of the back panel 6 and the flange portion 10a of the quarter pillar 10 are welded.
You.

[0004]

However, in the above-described conventional structure, when an external force is applied to the driver's cab 1 from the side , the internal structure of the door body of the vehicle is provided.
Part of the load acting on the impact bar
9 to the vehicle body side through the
The quarter pillar 10 may be deformed to the inside of the cab 1 near the triker 9 . Therefore, measures such as increasing the thickness of the quarter pillar 10 can be considered, but there is a problem that the weight increases and the cost increases.

An object of the present invention is to solve the above-mentioned problems of the conventional structure, and a quarter reinforcement is mounted below a lower side of a window frame of a back window provided at the rear of a driver's cab of a vehicle. Pillar and back
It is an object of the present invention to improve the rigidity of the panel and to obtain a joint structure between the back panel at the rear of the cab and the quarter pillar, which enhances the joint rigidity of the panels.

[0006]

In order to achieve the above-mentioned object, according to the present invention, the connecting structure of the back panel at the rear of the cab and the quarter pillar is provided with the right and left quarter pillars at the rear of the cab.
To each end of the back panel.
The reinforcement that constitutes the lower part of the window frame of the window
It is fixed to the back panel. In addition, the above-mentioned reinforcement

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a perspective view of a main part showing a driver's cab structure of a vehicle according to the present invention, and FIG. 2 is a perspective view showing a connecting part structure of a back panel and a quarter pillar according to the present invention on the driver's cab inner side. In the drawings, the same components corresponding to the conventional structure are denoted by the same reference numerals, and a part of the description is omitted.

[0010] quarter pillar 10 provided on the left and right side of the cab rear portion of the vehicle, because it requires a particularly large strength and rigidity, becomes closed cross section by a quarter outer panel 8a and quotas inner panel 8b Quarter pillar that joins the panels 8a and 8b
10 and a back part of the vehicle.
The left and right edges 6a of the flannel 6 are joined by welding. So
To make up the lower window frame of the back window
The reinforcement 7 is joined to the inner surface of the back panel 6.
You. Note that the reinforcement is sectioned as shown in the figure.
It is molded into a
Joint with the back panel 6
Construct a closed cross-section structure.

The left and right quarter pillars 10 have a door striker 9 for locking the door body 11 in a closed state.
Is installed. It should be noted, Doasutoraika 9 above Ryin
It is attached to the lower part of the back panel 6 at a substantially central portion in the vertical direction below the force 7 .

On the other hand, the inner surface of the back panel 6

And the width of the back panel 6
Close the center reinforcement 12 which has been molded shorter
It is joined to the cross-sectional structure. In addition, the center line phone
And the quarter inner panel 8b
Each is joined via a gusset 13. In addition, this
The gusset 13 of FIG.
A member molded to the same cross-sectional shape as the
Corner formed by the tinner panel 8b and the back panel 6
It has a shape bent along the part. Therefore, Quo
The external force applied to the inner panel 8b is

It is definitely transmitted.

That is, in this embodiment, the door strikers 9 attached to the left and right quarter pillars 10 are provided.
The back panel 6, the center reinforcement 12
And the gusset 13 are connected to each other via a closed cross-sectional structure . Accordingly, the coupling rigidity between the quarter pillar 10 and the back panel 6 is increased, and the rigidity of the back panel 6 below the window frame and the rigidity of the mounting position of the door striker 9 in the quarter pillar 10 are increased.
Become. For this reason, the deformation of the quarter pillar 10 can be minimized even with respect to an external force from the side direction.

Further, the lower side of the window frame of the back wind is constructed.
The resulting reinforcement 7 is fixed to the back panel 6.
If it does, it will be below and above reinforcement 7
Because the rigidity of the central part in the lower direction is low,
The back panel 6 vibrates and causes a muffled sound in the room
Sometimes. However, as in the present embodiment, the left and right
