Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cab structure for a truck, which has an improved drainage structure for draining rainwater and the like that has entered the side roof rails provided on both sides of the cab roof panel.

[0002]

[Prior art]

 As shown in FIG. 5, the drip channel in the cab of the truck is provided with a drip channel d having a U-shaped cross section on an upper portion of a side roof rail c composed of a side roof rail inner a and a side roof rail outer b. The side edge of the roof panel e of the channel d is spot-welded.

The drip channel d is provided on both sides of the cab in the front-rear direction, and rainwater flows inside the drip channel d and is drained from the front side of the cab.

However, in recent years, dripless side roof rails, in which the drip channels d on both sides of the roof panel have been eliminated, have also been adopted for truck cabs. This dripless structure is configured as shown in FIGS. 6 and 7. That is, 1 is a roof panel, and side roof rails 2 are provided on both sides of the roof panel.

A hollow back side rail 5 including a back inner 3 and a back outer 4 is provided on the rear side of the side roof rail 2. A hollow header side rail 8 including a header inner 6 and a header outer 7 is provided on the front side.

The front end of the backside rail 5 and the rear end of the header side rail 8 are connected to each other, and the front end of the header side rail 8 is connected to the front pillar 9. A reinforcing plate 10 is partially provided between the back inner 3 and the back outer 4 of the back side rail 5 and between the header inner 6 and the header outer 7 of the header side rail 8.

[0007] Further, the side edges on both sides of the roof panel 1 are provided with bent edges 1a which are bent downward, and the upper edges of the back outer 4 and the header outer 7 are also bent edges bent downward. 4a and 7a are provided.

The bent edge 1a and the bent edges 4a and 7a are spot-welded, and concave grooves 11 are formed on both sides of the roof panel 1. A body sealer 12 is applied to seal the bottom of the groove 11, that is, the spot welding between the bent edge 1a and the bent edges 4a and 7a in a watertight manner.

Further, in the cab, a plurality of mounting holes 13 are formed in the back outer 4 and the head outer 7 for mounting a roof deck (not shown) on the upper part of the roof panel 1, and the mounting holes 13 correspond to the mounting holes 13. The weld nut 14 is fixed to the reinforcing plate 10.

When the roof deck is not mounted, the mounting hole 13 is inserted into the mounting hole 13 in order to seal the mounting hole 13 in a watertight manner, and the seal type bolt 15 is screwed into the weld nut 14.

[0011]

[Problems to be solved by the device]

 However, in the dripless structure configured as described above, rainwater collected in the groove 11 provided at the joint between the roof panel 1 and the back outer 4 and the header outer 7 joins the back inner 3 and the back outer 4 together. There is a problem that it enters the inside of the side roof rail 2 from the joint part and the joint between the header inner 6 and the header outer 7.

Therefore, the body sealer 12 is applied in double or triple layers, but water leakage is unavoidable due to poor application, cracks, or the like. Further, the mounting hole 13 provided for mounting the roof deck is sealed by the seal type bolts 15. However, when the roof deck is mounted and a large load is applied, the periphery of the mounting hole 13 is easily deformed.

Therefore, even if the mounting hole 13 is closed by the seal type bolt 15 after the roof deck is removed, it is not possible to completely seal it in a watertight manner, and rainwater flows from the mounting hole 13 as shown by a dotted arrow. There is a problem that it flows and enters the inside of the side roof rail 2. Therefore, it has been a cause of rusting of the side roof rail 2.

The present invention has been made in view of the above circumstances, and its purpose is to prevent the rainwater from smoothly draining and collecting inside even if rainwater enters the inside of the side roof rail. It is to provide a cab structure of a truck that can be prevented.

[0015]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, this invention provides a hollow backside rail composed of a back inner and a back outer on both sides of the roof panel of the cab, and a header inner and a header outer on the front side. A hollow header side rail connected to the backside rail is provided, the front end of this header siderail is connected to the front pillar, and the front and rear slopes are lowered toward the front of the cab to the back inner and head inner. There is a drainage ditch.

[0016]

[Action]

 Water that has entered the inside between the back inner and back outer and between the header inner and header outer and the water that has entered through the mounting holes for mounting the roof deck is guided to the front of the cab by the drainage groove, and from the front pillar to the outside. Is drained.

[0017]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. The same components as those in FIGS. 6 and 7 are designated by the same reference numerals and the description thereof will be omitted.

As shown in FIG. 1 to FIG. 4, a step portion 21 is formed by projecting a lower side from an upper side of the back inner 3 forming the back side rail 5 to an inner surface side of the back outer 4. Are formed. Similarly, a step portion 22 is formed on the inner surface of the header inner 6 forming the header side rail 8 by projecting the lower portion from the upper portion to the inner surface of the header outer 7.

The step portion 21 of the back inner 3 and the step portion 22 of the header inner 6 are connected via a connecting portion between the back side rail 5 and the header side rail 8, and a front downward slope toward the front of the cab. Drainage groove 23 is formed. The header inner 6 and the header outer 7 are connected to the front pillar 9, and the drain groove 23 communicates with the hollow portion of the front pillar 9.

Rainwater collected in the groove 11 provided at the joint between the roof panel 1 and the back outer 4 and the header outer 7 comes from the joint between the back inner 3 and the back outer 4 and the joint between the header inner 6 and the header outer 7. When entering the inside of the side roof rail 2, rainwater flows down along the inner surface of the back inner 3 and the inner surface of the header inner 6, and when guided to the drain groove 23, is guided to the front of the cab by the drain groove 23, and inside the front pillar 9. It is drained outside through the car.

Further, the mounting hole 13 provided for mounting the roof deck is sealed by the seal type bolt 15. However, due to deformation of the periphery of the mounting hole 13 or the like, rainwater may leak from the gap between the seal type bolt 15 and the side roof rail. When it enters the inside of 2, the rainwater flows down along the inner surface of the back inner 3 and the inner surface of the header inner 6, and when it is guided to the drain groove 23, it is guided to the front of the cab by the drain groove 23 and the inside of the front pillar 9. It is drained outside through the car. Therefore, even if rainwater enters the inside of the side roof rail 2, it does not collect inside and is drained, so that rusting can be prevented.

[0022]

[Effect of device]

 As described above, according to the present invention, even if rainwater enters the inside of the side roof rail, the drainage groove provided inside the side roof rail smoothly drains the rainwater, so that the rainwater can be collected inside. It has the effect of preventing rust from occurring.
