Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an internal structure of a front part of a vehicle body of a truck.

[0002]

[Prior art]

 Conventionally, the structure inside the front panel of the front part of the truck body has been one in which the upper edge of one dash panel is attached to the vehicle body via the upper rain hose and the lower edge is fixed to the floor panel. . And the dash panel and other panels were fixed to each other by spot welding.

[0003]

[Problems to be solved by the device]

 Therefore, the instrument panels, air conditioners, brake clutches, accelerators, and other outfitting parts that are to be assembled to the dash panel must be loaded into the vehicle body in the main line of the assembly work, and the operator's Installation and installation work was done by hand. In this flow work, the dash panel has already been fixed inside the vehicle body, so the operator must carry the work with the parts inside the vehicle body, increasing the number of assembly steps and the work process. Due to the complexity, it took a significant amount of work time to improve productivity.

In the present invention, the dash panel is divided into two parts in advance, and the parts which can be attached to each panel are assembled in advance, and these dash panels are assembled to the vehicle body by bolts, nuts and adhesive welding. This is a device aimed at improving productivity by shortening work time and enabling automatic assembly using a work robot.

【Example】

 Figure 2 is a vertical side view of the front of the cab 5 with the dash panel attached. 8 is the front panel on the outside of the vehicle, 9 is the windshield on the front of the cab, and 10 is the joining of the front glass 9 and the front panel 8. It is a weatherstrip to keep the airtightness of the edges. Reference numeral 6 denotes an instrument panel installed in a substantially lateral direction in the front part of the operator's cab 5. The instrument panel 6 is provided with various instruments and ventilation mechanisms. The front edge 6a of the instrument panel 6 overlaps with the upper edge 4a of the front rain hose panel 4 and is fixed to the body of the vehicle body 11 by bolts 12 and nuts 13.

The dash panel 1 disposed so as to face the inside of the front panel 8 is divided into an upper portion 2 and a lower portion 3. A bracket 14 for installing a brake and a clutch is arranged on one side of the upper portion 2, and a lower end portion 14b of a front surface 14a of the bracket 14 is fixed to a lower portion of the upper portion 2 by a bolt 12 and a nut 13. To do. An air conditioning mechanism 15 is arranged on the other side of the upper portion 2, and a front wall 15b of a casing 15a of the air conditioning mechanism 15 is fastened and fixed by bolts 12 and nuts 13.

Then, as shown in FIG. 4, the upper edge 2a of the upper part 2 of the dash panel 1 to which the bracket 14 and the air conditioning mechanism 15 are fixed is tightened and fixed to the rain hose panel 4 by the bolt 12 and the nut 13. The upper end 14c of the front surface 14a of the bracket 14 is fixed to the lower edge 4b of the front rain hose panel 4, and the rear upper edge 14d of the bracket 14 is fixed to the rear edge 6b of the instrument panel 6. It is fixed to the panel 16.

Further, as shown in FIG. 5, a tongue piece 17 protruding from the upper edge portion of the rear wall 15c of the casing 15a of the air conditioning mechanism 15 is fixed to the rear edge 6b of the instrument panel 6.

Furthermore, as shown in FIG. 6, one end 18a of the engine control mechanism 18 is rotatably connected to one side of the lower portion 3 of the dash panel 1, and the other side is connected to the one side of FIG. The wiring and piping mechanism 19 is attached directly or via the bracket 20 as shown in FIG.

Then, the upper edge 3 a of the lower portion 3 to which the engine control mechanism 18 and the wiring and piping mechanism 19 are attached is fastened and fixed to the lower edge 2 b of the upper portion 2 with the bolt 12 and the nut 13.

As shown in FIG. 8, a flange 4c is formed on the lower edge 4b of the front rain hose panel 4, and a flange 2c is formed on the lower edge 2b of the upper portion 2 of the dash panel 1. An adhesive 21 is filled in 4c and 2c, and the upper edge 2a of the upper portion 2 to which the respective members are attached is adhesively fixed to the lower edge 4b of the front rain hose panel 4. Further, the upper edge 3b of the lower portion 3 to which each member is attached may be fixedly adhered to the lower edge 2b of the upper portion 2.

[0013]

[Effect of device]

 Therefore, according to the present invention, the dash panel is divided into an upper portion and a lower portion, and a bracket for installing brakes and clutches, an air conditioning mechanism, an engine control mechanism, a piping mechanism, etc. are attached to each of them in advance. Since the upper part and the lower part where the members are fixed are fixed to the body of the vehicle body via the rain hose, the assembling work can be simplified, the work speed can be improved, and the production efficiency can be improved. Can be done.
