Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a coupling structure of a back panel at a rear portion of a driver's cab and a quarter pillar in a vehicle such as a pickup-type truck in which a driver's cab and a luggage compartment are separately configured.

[0002]

[Prior art]

 Generally, in a vehicle such as a pickup truck in which a driver's cab and a luggage compartment are separately configured, a driver's cab 1 has a dash panel portion 2 formed by press-molding a rolled steel plate as shown in FIGS. 5 and 6. The roof panel 3, side members 4, floor panel 5, back panel 6 and other parts are welded in an automatic assembly line or the like to form a box-shaped skeleton structure.

Further, parts such as the quarter pillars 10 provided on the left and right sides of the rear part of the cab 1 that require particularly high strength and rigidity, and the window frame part of the back window have a closed cross-section structure. As shown in FIGS. 7 and 8, the reinforcement 6 formed in a hat-shaped cross section is joined inside the lower side of the window of the back panel 6 in a closed cross-section structure. Further, the quarter pillar 10 has a closed cross-section structure by a quarter outer panel 8a and a quarter inner panel 8b, and the left and right edge portions 6a of the back panel 6 and the flange portion 10a of the quarter pillar 10 are welded and joined together. There is.

[0004]

[Problems to be solved by the device]

 However, in the above-described conventional structure, when an external force is applied to the driver's cab 1 of the vehicle from the side direction, the impact bar and the like are installed in the internal structure of the door body of the vehicle. Since the door striker 9 installed below the window frame of the quarter pillar 10 is connected, the vicinity of the door striker 9 of the quarter pillar 10 is located inside the cab 1 as the door is deformed. It may be deformed. Therefore, measures such as increasing the plate thickness of the quarter pillar 10 may 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. A centering force is installed below a window frame portion provided at a rear portion of a driver's cab of a vehicle, and a quarter pillar and a back pillar are attached. This is to obtain a joint structure between the back panel at the rear of the cab and the quarter pillars, which enhances the joint rigidity with the panel portion.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the connecting structure of the rear panel of the cab and the quarter pillar according to the present invention is such that the both ends of the back panel are joined to the left and right quarter pillars at the rear of the cab, and the window frame portion of the back panel is joined. Attach the door striker at the bottom of both ends of the reinforcement force, which is located approximately in the middle of the quarter pillar in the vertical direction of the back panel, and inside the back panel on the line connecting the left and right door strikers. A centering force molded into a hat-shaped cross section is joined to form a closed cross-section structure, and a predetermined cross-sectional shape is formed between the ends of the centering force and the quarter inner panel that constitutes the quarter pillar. It is characterized by joining the gusset.

[0007]

[Action]

 Based on such a configuration, in the present invention, a closed-section center reinforcement for connecting the quarter pillar and the back panel is attached below the window frame portion provided at the rear part of the cab of the vehicle. Even if an external force is applied to the cab of the vehicle from the side, the rigidity of the quarter pillar and the back panel is high, and deformation of the quarter pillar can be minimized.

[0008]

【Example】

 Hereinafter, embodiments of the present invention will be described 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 of a driver's cab inner side showing a structure of a joint between a back panel and a quarter pillar according to the present invention. Therefore, in the figure, the same parts corresponding to the conventional structure are designated by the same reference numerals, and a part of the description is omitted.

Since the quarter pillars 10 provided on the left and right sides of the cab rear portion of the vehicle require particularly high strength and rigidity, the quarter pillar 10 has a closed cross-section structure by the quarter outer panel 8a and the quarter inner panel 8b. The flange portion 10a of the quarter pillar 10 and the left and right edge portions 6a of the back panel 6 are joined by welding. Then, in order to form a window frame portion of the back window in the rear part of the operator's cab 1, a line hose 7 formed in a hat-shaped cross section is joined in a closed cross-section structure inside the lower side of the window of the back panel 6. .

A door striker 9 that locks the door body 11 in a closed state is attached to the left and right of the quarter pillar 10, and the attachment position of the door striker 9 is joined to the quarter pillar 10 and is a back. The reinforcement 7 that constitutes the window frame portion of the window is mounted below the both edge portions of the reinforcement 7 and at a substantially intermediate portion in the vertical direction of the back panel 6.

On the other hand, on the line connecting the left and right sides of the door striker 9 attached to the quarter pillar 10, the inside of the back panel 6 is formed in a hat-shaped cross section, and is formed shorter than both ends of the back panel 6. The centered reinforcement 12 is joined to the closed cross-section structure. Further, between the both ends of the centering force 12 and the corners of the quarter inner panel 8b forming the quarter pillar 10, the end of the centering force 12 and the quarter inner panel 8b are provided. A gusset 13 having a predetermined cross-sectional shape to be joined is joined by welding.

Therefore, according to the embodiment of the present invention configured as described above, on the line connecting the left and right sides of the door striker 9 attached to the quarter pillar 10, inside the back panel 6, in a hat-shaped cross section. A quarter inner panel that is formed by joining the center reinforcement 12 that is formed shorter than both ends of the back panel 6 into a closed cross-section structure and that constitutes both ends of the above center reinforcement 12 and the quarter pillar 10. Since the gusset 13 having a predetermined cross-sectional shape is welded to the 8b, the joint rigidity between the quarter pillar 10 and the back panel 6 is increased, and against the external force from the side direction of the cab. Also, the deformation of the quarter pillar 10 can be suppressed to a minimum.

[0014]

[Effect of device]

 As described in detail above, according to the present invention, both ends of the back panel are joined to the right and left quarter pillars at the rear of the operator's cab, respectively, and the lower ends of both ends of the reinforcement for forming the window frame portion of the back panel are joined. The door striker is located approximately in the middle of the quarter pillar in the up and down direction of the back panel, and the center line is formed into a hat-shaped cross section inside the back panel on the line connecting the left and right door strikers. Since the reinforcement was joined to the closed cross-section structure, and the gussets molded to the predetermined cross-sectional shape were joined between the both ends of the centering force and the quarter inner panel forming the quarter pillar, the quarter pillar's There is no need to increase the plate thickness, and the rigidity of the connection between the quarter pillar and the back panel is increased. Against the external force, it is possible to suppress to a minimum the deformation of the quarter pillar.
