Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an improvement in the body structure of a cab.

(Prior art) For the front body of the cab, various pipes and wirings are installed in the space between the front outer panel and the front inner panel. It is known that the front lid is an openable lid.

By the way, under the cab front body, headlamps are usually arranged on both sides, and front grilles are arranged between the lamps. Further, the inner panel of the front body is provided with a ventilation hole that opens to the cab.

Then, the running wind from the front grille opening flows rearward through the radiator below the front panel, and a part of it collides with the lower part of the front inner panel and rises along the gap in the front body and supplies it to the ventilation hole. It is supposed to be done.

For this reason, for example, when traveling in the rain, raindrops blown in with the outside air enter the voids in the front body and enter the driver's cab through ventilation holes or the like.

Therefore, a front grill has been proposed in which a part of the grill opening facing the lower portion of the inner panel of the front body is closed (Actual Publication No. Sho 63-2325,
63-2326 publication).

(Problems to be solved by the invention) However, in such a conventional example, since the grill opening area is reduced in order to block the invasion route of raindrops and the like, the cooling performance of the radiator deteriorates accordingly. there were.

(Means for Solving the Problem) In order to solve such a problem, the present invention has a cab body structure in which an outer panel of the front body is an openable front lid. In addition to forming a ventilation hole that guides the running wind from the grill opening to the rear radiator on the floor cross member facing the front grill, the upper part of the grill on the back of the front lid is located between the lid and the front inner panel. A partition plate extending toward the ventilation opening of the floor cross member is provided so as to block the gap,
The rear end of the partition plate is extended so as to face the inside of the ventilation port of the floor cross member.

(Operation) The amount of air flowing from the front grille opening is reliably regulated by the partition plate with its rear end facing the ventilation opening of the floor cross member, and the amount of air passing through the radiator is regulated accordingly. Will increase. Therefore, the effect of preventing raindrops from entering the cab and the radiator performance are surely improved.

(Embodiment) In FIG. 1.2, reference numeral 1 is an openable front lid provided on the cab front body 2, and the front lid 1 is attached to the lower part of the front window 3 via left and right hinges (not shown) at the upper side.

A front grill 4 is integrally formed on the lower portion of the front lid 1, and a partition plate 5 described later is screwed to the inner surface of the lid 1 at the base end.

A floor cross member 7 is attached to the lower end of the inner panel 6 of the front body 2 with the opening side of the substantially U-shaped cross section facing the grill opening 4A, and the traveling wind from the grill opening 4A is attached to the bottom of the cross member 7. A ventilation port 9 that leads to the rear radiator 8 is formed.

In this case, the partition plate 5 is arranged as described above for a part of the grille opening 4A due to the positional relationship with the ventilation hole 10 opened in the inner panel 6 of the front body 2 (see FIG. 1), A space 11 between the lid 1 and the inner panel 6 is diagonally crossed, and a rear end portion thereof is extended so as to face the ventilation port 9 of the floor cross member 7 (see FIG. 2).

Based on such a configuration, the traveling wind from the grill opening 4A of the front lid 1 is guided to the inside of the ventilation opening 9 of the floor cross member 7 through the partition plate 5, so that the front portion of the front of the floor cross member 7 is prevented. It does not flow into the voids 11 in the body 2 and surely flows toward the radiator 8. Therefore, the amount of air passing through the radiator 8 is increased to obtain good cooling performance, and it is possible to effectively prevent raindrops and the like from entering the gap 11.

(Effects of the Invention) In short, according to the present invention, the front grill is integrally formed in the lower portion of the front lid, and the floor cross member facing the front grill guides the traveling wind from the grill opening to the rear radiator. A partition plate extending toward the ventilation opening of the floor cross member so as to shield the gap between the lid and the front inner panel from the upper portion of the grill on the rear surface of the front lid while forming the opening, and the rear end of the partition plate. By extending the part so that it faces the inside of the ventilation port of the floor cross member, the running wind is prevented from flowing into the air gap inside the front body, so it is possible to ensure that raindrops etc. do not enter the cab. It is possible to obtain the effect that the radiator performance can be improved while preventing the above.
