Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of a dust baffle that closes the gap between the cabin of a vehicle and the front surface of a deck.

[Prior Art] In cab-over type trucks (Fig. 4), etc., in order to prevent the cargo loaded on the deck D from falling into the engine room E below the cabin C,
A dust bump 1 is provided on the rear surface of the cabin C. As shown in FIG. 5, the dust buttful 1 has a base 11 fixed to a mounting flange C1 provided in the vehicle width direction at the lower end of the rear surface of the cabin C, and the tip of a buttful plate 12 extending rearward from the base 11 is fixed to the mounting flange C1. D
It is brought into contact with a protruding piece D1 provided on the front surface of. This closes the gap F between the cabin C and the front surface of the deck D, and prevents the loaded items falling from the deck D from reaching the engine room E below the cabin C.

[Problems to be solved by the invention] By the way, when installing the deck D on the chassis, first place the rear end of the deck D on the chassis (dashed line in Figure 4), and then move the deck D from the inclined position. Lower the front end of deck D as shown by the arrow. During this lowering, the protruding piece D1 of the deck D comes into contact with the upper surface of the baffle plate 12 and pushes it down (as shown by the chain line in FIG. 5). In this state, the falling object stays at the contact area between the bumpy plate 1 and the protruding piece D1, and when a small gap is created between the bumpy plate 12 and the protruding piece D1 due to vehicle vibration, the falling object enters the engine room E. . Therefore, after mounting the deck D, it was necessary to lift the buttful plate 12 onto the protrusion D1 as shown in the figure.

In view of the above-mentioned problems, the present invention aims to provide a dust baffle for a vehicle that does not require a step of lifting the baffle plate 12 and can reliably block falling objects.

[Means for Solving the Problems] The dust baffle 1 (FIG. 1) of the present invention includes a base 11 fixed to the cabin C, an upper baffle plate 12a branching from the base 11 and having a V-shaped cross section, and a lower buffle. It is composed of a plate 12b, and a branch part 13
is assumed to be elastically deformable.

[Function] When the deck is mounted, when the front end of the deck D is lowered as shown by the arrow in the figure, the protrusion (deck plate) D1 provided on the front surface of the deck D moves to the lower buttress plate 12b.
, and the entire baffle plates 12a, 12b are pushed back as shown by the arrows. Thus, when the deck mounting is completed (FIG. 3), the tip of the upper baffle plate 12a comes into contact with the front surface of the deck D, and the gap F between the cabin C and the front surface of the deck D is closed.

[Effects] In the dust baffle 1 of the present invention, the upper buffle plate 12a is branched from the lower buffle plate 12b, which is tilted backward by the deck plate D1 when the deck D is mounted, and the upper buffle plate 12a is provided above this. When the mounting is completed, the tip of the upper buffle plate 12a, which is tilted back integrally with the lower buffle plate 12b, comes into pressure contact with the front surface of the deck D, thereby reliably closing the gap F between the cabin C and the deck D. This prevents objects falling from the deck D from entering the engine room E.

According to the present invention, there is no need for the conventional process of lifting the buttful plate.

[Example] In FIGS. 1 and 2, a mounting flange C1 extending in the vehicle width direction is formed at the lower end of the rear surface of a cabin C of a cab-over type vehicle (FIG. 4). Dust Batsuful 1 is stuck on it. The dust baffle 1 is an extrusion molded product of synthetic resin, and consists of a base 11 wrapped around the flange C1, and an upper buffle plate 12a and a lower buffle plate 12b branching from the base 11 and having a V-shaped cross section. When fixed to the flange portion C1, the upper baffle plate 12a stands upright as shown in the figure, so as not to interfere with the deck plate D1 provided on the front surface of the deck D when the deck D is mounted.

The lower baffle plate 12b extends diagonally rearward, and its tip is located in the movement path of the deck plate D1 when the deck is mounted. The branch portions 13 of both buff-full plates 12a, 12b are made thin so that they can be elastically deformed.

When mounting the deck D on the chassis S,
Place the rear end of the deck D on the chassis S (dashed line in Figure 4), and lower the front end of the deck D from the inclined position of the deck D as shown by the arrow in Figure 4. During this descent,
The deck plate D1 (FIG. 1) abuts and engages the lower buffle plate 12b, and as the deck D descends, the entire buffle plates 12a, 12b move toward the branch portion 13.
Fall backwards with the center at the center (arrow in Figure 1). When the installation of the deck D is completed, as shown in FIG. 3, the tip of the upper buffle plate 12a that is tilted backward above the deck plate D1 is pushed back against the deck by the backward force acting through the lower buffle plate 12b. It is pressed against the front surface of deck D, and the gap F between the cabin C and deck D is reliably closed.

Further, since the pressure contact portion of the buff-full plate 12a is located above, falling objects are allowed to slide down toward the base 11 without staying at this portion. In this way, the loaded items that fall from deck D are
It is prevented from reaching the engine room E below the cabin C.

According to the dust baffle having the above structure, there is no need for the conventional step of lifting the buffle plate onto the deck plate D1 when the deck D is finished being mounted.

Further, in the embodiment described above, the upper surface and tip of the lower baffle plate 12b are in pressure contact with the deck plate D1 and the front surface of the deck D, respectively, and this also seals the fallen object.
