Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a mounting structure for an intake snorkel in a truck or the like.

(Prior Art) In a truck or the like, an intake snorkel is used in order to suck in combustion air for an engine from a high place where there is as little dirt and dust as possible.

As shown in FIG. 2 and FIG. 3, the conventional intake snorkel 1 has a duct cover fixed to the upper end of the rear outer panel 4 of the cabin 2 extending vertically with a slight distance from the rear outer panel 4. An intake port 1b is formed on the lower surface of 1a, and its lower end is connected to an air cleaner (not shown).

This intake snorkel 1 is fastened by fastening a bracket 1c fixed on the upper back surface thereof to a rear outer panel 4 and a bolt 7 planted on a reinforcing bracket 6 which is spot-welded 5 behind this, with a nut 14 screwed. There is.

In FIGS. 2 and 3, 8 is a rear inner panel, 9 is a side outer panel, 10 is a side inner panel, 11 is a roof panel, 12 is a rear window, and 13 is a rear window.
Is a side window.

(Problems to be Solved by the Invention) In the above-described conventional structure, since the intake snorkel is fastened only to the rear outer panel 4 and the reinforcing bracket 6 and has low rigidity, the intake snorkel 1 is affected by the pulsation of the intake air passing therethrough. When vibrating, this vibration is transmitted to the rear inner panel 8 via the rear outer panel 4, which causes a problem that noise is generated in the vehicle interior.

(Means for Solving the Problems) The present invention focuses on the fact that a rear inner panel is arranged in close proximity to the rear outer panel, and the rear inner panel is used to mount the intake snorkel mounting portion. The purpose of this is to improve the rigidity of the rear outer panel and the inner inner panel of the cabin by forming waves with the same pitch and with the same pitches on the rear outer panel and the troughs of these rear outer panels. An intake snorkel mounting structure is characterized in that a mountain portion of a rear inner panel and a reinforcing bracket arranged between them are spot-welded together, and an intake snorkel is fastened to the outer panel and the reinforcing bracket.

(Operation) Since the present invention has the above-mentioned structure, the three parts of the rear inner panel, the rear outer panel and the reinforcing bracket are integrated, and the three parts form a plurality of box-shaped closed cross-section structures. Therefore, the rigidity of the mounting portion of the intake snorkel is improved.

(Embodiment) One embodiment of the present invention is shown in FIG.

Waves of the same pitch are formed on the rear outer panel 4 and the rear inner panel 8, respectively, with irregularities being opposite to each other. Further, the rear outer panel 4 is attached to the reinforcing bracket 6.
Waves of the same shape as are formed. Then, the reinforcing bracket 6 is attached to the back of the rear outer panel 4, and the valley portions of the rear outer panel 4 and the reinforcing bracket 6 and the peak portions of the rear inner panel 8 are spot-welded 5 to make these three members work. A plurality of box-shaped closed cross-section structures are integrated.

Other configurations are similar to those of the conventional one shown in FIGS. 2 and 3, and corresponding members are designated by the same reference numerals.

(Effect of the Invention) In the present invention, the rear outer panel and the rear inner panel of the cabin are formed with waves having the same pitch with the unevenness, and the troughs of the rear outer panel and the peaks of the rear inner panel and these Spot welding the reinforcing brackets arranged together, and fastening the intake snorkel to the outer panel and the reinforcing bracket,
The rear inner panel, the rear outer panel, and the reinforcing bracket are integrated into one body, and a plurality of box-shaped closed cross-section structures are formed by these three bodies, so that the rigidity of the mounting portion of the intake snorkel is improved. As a result, noise in the passenger compartment can be reduced and the reinforcing bracket can be downsized, so that its weight and cost can be reduced.
