More specifically, the present invention relates to a structure that reinforces a bank portion provided on both side edges of a recess formed in the roof panel of the cab so as to extend in the traveling direction of the vehicle.

[0002]

[Prior art]

 Conventionally, as this type of vehicle, there has been disclosed a crane transport vehicle in which a concave portion is formed in a central portion of a roof of a cab in which a driver's seat and a passenger's seat are arranged side by side in a lateral direction of the vehicle and extends in a traveling direction of the vehicle. (Actual Kosho 48-23361). This crane transport vehicle does not narrow the cab, facilitates contact between the driver sitting in the driver's seat and the passenger sitting in the passenger seat, and secures a sufficient field of view to the side of the driver's seat. In addition, the boom of the crane is housed in the recess so that the boom can be moved in a low position.

On the other hand, in an on-vehicle vehicle that loads and transports a plurality of small vehicles such as passenger cars, an on-vehicle platform is attached to the rear portion of the vehicle instead of the loading platform. This on-vehicle stand extends to above the roof panel of the cab in order to efficiently load small vehicles, and a recess is formed in the roof panel to minimize the vehicle height.

[0004]

[Problems to be solved by the device]

 The above-mentioned crane transport vehicles and vehicle-mounted vehicles are usually manufactured by modifying the trucks that are mass produced in order to minimize the increase in manufacturing costs. However, in the above-mentioned mobile cranes and vehicle-mounted vehicles, if the width of the recess is widened to be slightly smaller than the vehicle width, the thickness of the pair of embankments provided on both side edges of the recess will be smaller than its height. Therefore, there was a problem that the rigidity of the bank decreased.

An object of the present invention is to provide a cab roof reinforcing structure capable of increasing the rigidity of a bank by adding parts having a simple shape and slightly increasing the number of assembling steps.

[0006]

[Means for Solving the Problems]

 A configuration of the present invention for achieving the above object will be described with reference to FIGS. 1 and 4 corresponding to an embodiment. According to the present invention, a roof panel 12 forming an upper surface of a cab 11, an outer opening 18a formed on an outer surface of the cab, which is connected to a side edge of the roof panel 12 and an outer flange 18b is formed on a peripheral edge of the outer opening 18a. The quarter outer panel 18 is provided with an inner opening 19a having substantially the same shape as the outer opening 18a at a position facing the outer opening 18a, and an inner flange 19b is formed at a position facing the outer flange 18b. A quarter inner panel 19 having an inner flange portion 19b joined to the outer flange portion 18b, and a pair of embankment portions provided on both side edges of the recess portion 16 by forming a recess portion 16 extending in the vehicle traveling direction on the roof panel 12. It is a cab provided with 17, 17, and reinforces the bank portion 17 inside the bank portion 17. A strong member 23 is provided so that the cross section of the bank portion 17 becomes a closed cross section by the reinforcing member 23, and one end of the reinforcing member 23 forms the upper edges of the outer opening 18a and the inner opening 19a. It is joined between the outer flange portion 18b and the inner flange portion 19b, and the other end is joined to the inner surface of the bank portion 17 that straddles above the inner flange portion 19b and faces the inner flange portion 19b.

[0008]

【Example】

 Next, an embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1 to 4, an on-vehicle vehicle has a vehicle-mounted base (not shown) mounted on the rear portion of the vehicle for mounting a plurality of small vehicles such as passenger cars. The on-vehicle base efficiently loads small-sized vehicles. In order to do so, the cab 11 is extended and mounted on the roof panel 12. The cab 11 of an in-vehicle vehicle is manufactured by modifying a cab of a mass-produced truck, and includes a roof panel 12 that forms an upper surface of the cab 11, a quarter panel 13 that forms a rear side surface of the cab 11, and a rear surface of the cab 11. A back panel 14 to be formed, a recess 16 extending in the vehicle traveling direction on the roof panel 12 and accommodating the front part of the vehicle mount, and a pair of bank portions 17, 17 provided on both side edges of the recess 16. (Fig. 4).

The quarter panel 13 includes a quarter outer panel 18 having an outer opening 18a formed substantially in the center thereof, and a quarter outer panel 18 having an inner opening 19a having substantially the same shape as the outer opening 18a formed at a position facing the outer opening 18a. It has an inner panel 19. An outer flange portion 18b is formed on the periphery of the outer opening portion 18a, an inner flange portion 19b is formed on the periphery of the inner opening portion 19a facing the outer flange portion 18b, and the inner flange portion 19b is formed on the outer flange portion 18b. To be joined. A window glass 22 for closing the outer opening 18a and the inner opening 19a is attached to the outer flange 18b and the inner flange 19b through a weather strip 21 (FIGS. 1 and 2). Also, the upper end of the quarter inner panel 19 is cut upward by a predetermined distance from the inner flange portion 19b.

In this example, the recess 16 is formed on an inclined surface that descends from the substantially central portion of the cab 11 toward the back panel 14, and the upper edge of the bank portion 17 is formed to extend substantially horizontally. Since the width of the concave portion 16 is formed so as to be slightly smaller than the vehicle width, the thickness of the bank portion 17 is smaller than its height. The roof panel 12 has a roof panel body 12a forming an inclined surface of the concave portion 16 and a connecting plate 12b having a substantially L-shaped cross section which is connected to a side edge of the roof panel body 12a and forms an inner side surface of the bank portion 17. The outer surface of the bank portion 17 is formed by a quarter outer panel 18, and the upper edge of the bank portion 17 is formed by bending the quarter outer panel 18 inward toward the upper end of the connecting plate 12b. The upper end of the connecting plate 12b connected to the roof panel body 12a is connected to the inner edge of the quarter outer panel 18 (FIGS. 1 and 3).

The characteristic configuration of this embodiment is that a reinforcing member 23 for reinforcing the bank portion 17 is provided inside the bank portion 17 so that the cross section of the bank portion 17 is closed by the reinforcing member 23. It's being constructed. The reinforcing member 23 is formed by bending a plate material having a predetermined width into a channel shape in cross section. By bending the inner flange portion 19b forming the upper edges of the openings 18a, 19a of the inner flange portion 19b joined to the outer flange portion 18b in a direction substantially away from the outer flange portion 18a in a substantially U-shaped cross section, A gap 24 into which one end of the reinforcing member 23 can be inserted is formed. One end of the reinforcing member 23 is inserted into the gap 24 and joined to the outer flange portion 18b and the inner flange portion 19b. The other end of the reinforcing member 23 is joined to the inner surface of the bank portion 17 that faces the inner flange portion 19b across the upper end of the quarter inner panel 19, that is, the inner surface of the connecting plate 12b (FIGS. 1 and 2).

Further, the inner lower end of the bank portion 17 in front of the openings 18 a and 19 a is welded to the upper end of the seat belt anchor stiffener 26 and has a first connecting plate 31 having a T-shaped cross section together with the stiffener 26, and a quarter inner panel. A second tie plate 32, which is welded to the upper end of 19 and is in close contact with the lower surface of the first tie plate 31, is provided. The seat belt anchor caster 26 and the quarter inner panel 19 are in close contact with each other below the bank portion 17, and the nut 34 welded to the plate 33 is fastened with the bolt 37 via the seat belt holder 36, the stiffener 26 and the quarter inner panel 19. It is screwed. The first connecting plate 31 is in close contact with the lower surface of the connecting plate 12b and is joined to the side edge of the roof panel body 12a together with the connecting plate 12b, and the second connecting plate 32 is joined to the connecting plate 12b together with the first connecting plate 31 (Fig. 3). By adding simple shaped parts such as the first tie plate 31 and the second tie plate 32, the rigidity of the bank portion 17 in front of the openings 18a and 19a can be increased. 38 is a head lining (FIGS. 1 and 3).

In the cab roof reinforcing structure thus configured, the bank portion 17 is configured by the quarter outer panel 18, the connecting plate 12b and the reinforcing member 23 so that the cross section has a closed cross section. The rigidity of can be increased. Further, since it is possible to add a reinforcing member 23 having a simple shape and to join the reinforcing member 23 to the inside of the bank portion 17, a slight increase in the number of assembling steps is required, so that an increase in manufacturing cost can be small.

In the above embodiment, the roof panel is composed of the roof panel main body and the connecting plate, but this is an example. If the roof panel can be deep-drawn, the roof panel main body can be used without using the connecting plate. May be directly connected to the quarter outer panel. If the quarter outer panel can be deep-drawn, the bank part may be formed with one quarter outer panel without using a connecting plate, and the quarter outer panel may be directly connected to the roof panel body. Further, although the vehicle-mounted vehicle is described in the above-mentioned embodiment, the vehicle is not limited to this, and may be a fire truck, a crane vehicle, or any other vehicle as long as the vehicle has a recessed portion formed in the roof panel extending in the traveling direction of the vehicle.

[0015]

[Effect of device]

 As described above, according to the present invention, the roof panel is provided with the recess extending in the traveling direction of the vehicle, and the reinforcing member for reinforcing the bank is provided inside the pair of bank provided on both side edges of the recess. Since the cross section of the bank portion is closed by the reinforcing member, the rigidity of the bank portion can be increased. In addition, one end of the reinforcing member is joined between the outer flange portion and the inner flange portion forming the upper edges of the outer opening portion and the inner opening portion, and the other end faces the inner flange portion across the upper side of the inner flange portion. Since the structure is only joined to the inner surface of the embankment, simple shaped parts can be added and the assembly man-hours can be slightly increased, and the cab roof can be reinforced at low cost.
