Description

Baffle for Fuel Tank < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a baffle, and more particularly, to a baffle for a fuel tank in which the length of the baffle is shortened before being assembled by superimposing the baffle in the longitudinal direction.

Generally, fuel tanks are subject to smooth fuel supply due to generation of swirling or sudden braking which causes the size of the vehicle's inertia force to become large, or fuel leaking or swaying due to internal inertia during rapid acceleration.

Therefore, in the internal space of the fuel tank, a baffle which necessarily divides the internal space into a plurality of spaces and prevents one side of the oil surface from being caused by the inertia force of the fuel is necessarily applied.

By applying such a baffle, it is possible to prevent one side of the oil surface from leaning or leaning which contributes to maintenance of the fuel supply performance of the fuel tank even when the vehicle is turning, sudden braking or rapid acceleration. In addition, by applying a baffle, the noise due to oil level swelling in the fuel tank can be reduced.

Therefore, the durability of the holder positioner 15 is enhanced by concentrating the vertical beads 12 in the holder positioner 15.

The baffle plate 10 is formed with a clip positioner 17 between two holder positioners 15 formed on the left and right fixing portions 10-1 and 10-2, The baffle clips 50-1 and 50-2 can be detachably fixed and separated from each other.

3 shows the details of the first, second, third, and fourth baffle connectors 20-1, 20-2, 20-3, and 20-4, the first and second baffle clips 50-1 and 50-2, Respectively.

As shown in the figure, the first, second, third, and fourth baffle connectors 20-1, 20-2, 20-3, and 20-4 include a holder 30 having the same shape and structure, And a clip 40.

The holder 30 includes an inlet body 31 and a hook body 32 which are stepped on each other and an insertion hole 33 is passed through the inlet body 31 and the hook body 32, A plurality of inside legs 35a, 35b, 35c and 35d are formed inside the insertion hole 33 to narrow the inside diameter of the insertion hole 33. [

The inlet body 31, the hook body 32, and the insertion hole 33 are formed in a square polygonal shape.

The inside legs 35a, 35b, 35c and 35d are made up of first, second, third and fourth inside legs 35a, 35b, 35c and 35d, and the first inside leg 35a and the third inside leg 35c And the second inside leg 35b and the fourth inside leg 35d are opposed to each other at regular intervals.

In particular, the inner legs 35a, 35b, 35c, and 35d extend downward from the inlet body 31 toward the lower side of the hook body 32 so that a fixer 200 (see FIG. 5) (33) so that the fixing force can be strengthened.

The holder 30 is further provided with a pair of outer side jaws 37 protruding from the outer circumferential surface of the hook body 32. The outer side jaw 37 is fixed to the holder positioner 15 of the baffle plate 10, The holder 30 is engaged with the holder positioner 15 formed in the left and right fixing portions 10-1 and 10-2 of the baffle plate 10, 15) so as to maintain a fixed state.

The holder clip 40 is formed in a square shape having an insertion hole 41 and is formed at a position where the first and second fins 43a and 43b are opposed to each other around the insertion hole 41. [ Therefore, the holder clip 40 can be fixed using the rim of the holder positioner 15 formed on the left and right fixing portions 10-1 and 10-2 of the baffle plate 10, respectively.

The first and second baffle clips 50-1 and 50-2 have the same shape and structure. For example, each of the first and second baffle clips 50-1 and 50-2 may be formed of an elastic body having an inner space formed with an opening opened to one side, and both left and right sides of the opened mouth of the elastic body The side pressing portion 51 is formed as a portion of the elastic body, and the upper surface pressing portion 53 is formed at a closed position opposite to the opening of the elastic body.

Therefore, when the first and second baffle clips 50-1 and 50-2 are respectively fitted to the clip positioner 17 formed on the left and right fixing portions 10-1 and 10-2 of the baffle plate 10 The upper surface pressing portion 53 is brought into close contact with the top of the diamond shape of the clip positioner 17 and the side pressing portion 51 is brought into close contact with both sides of the diamond shape of the clip positioner 17 to maintain the fixing force.

On the other hand, Fig. 4 shows the shape of the compressed state baffle 1-1 in which the overall length of the baffle 1-1 according to the present embodiment is reduced.

As shown in the figure, if the force F is applied in a state having the total length (La-1) corresponding to the width (or overall length) of the fuel tank (or oil tank) The baffle 1 is deformed into the compression baffle 1-1 having the shortened overall length La-2 whose overall length La-1 is shortened.

For example, when a force F is applied to the right fixing portion 10-2 of the baffle plate 10 to push it toward the left fixing portion 10-1, the right folding portion 10-2 pushed by the right fixing portion 10-2 The portion 10-5 is shifted to the collapsed state while being pushed toward the connection portion 10-3. Therefore, the length of the right fixing portion 10-2 - right folded portion 10-5 is shortened.

At this time, the connection section between the connection section 10-3 and the right folded section 10-5 and the connection section between the right folded section 10-5 and the right fixing section 10-2 have different thicknesses t1, t2 and t3 So that easy deformation occurs (see Fig. 1).

Next, when the connection portion 10-3 of the baffle plate 10 is again pushed toward the left fixing portion 10-1 by applying the force F, the connection portion 10-3 and the left folded portion 10-4 Is pushed to the left fixing portion 10-1 and overlaps to some extent. Therefore, the length of the left fixing part 10-1-left folded part 10-4-connection part 10-3 becomes somewhat shorter.

Due to this, the compression baffle 1-1 can be switched to the uniaxial full-length length La-2 in which the baffle plates 10 are superimposed on each other and overlapped.

5 shows a state in which the baffle 1 according to the present embodiment is installed in the internal space of the fuel tank 100. As shown in Fig.

As shown in the figure, the operator places the right fixing portion 10-2 of the baffle plate 10 in the fuel tank 100 with the third and fourth baffle fixing portions 120-3 and 120-4, The baffle 200 is fastened to each of the third and fourth baffle fixing portions 120-3 and 120-4 in the same manner as the two baffle fixing portions 120-1 and 120-2, 3 and 20-4 are assembled to the fuel tank 100 by two fixers 200, respectively.

In this way, four fixers 200 are fastened to the first, second, third and fourth baffle fixing parts 120-1, 120-2, 120-3, and 120-4 of the fuel tank 100, Each of the three or four baffle connectors 20-1, 20-2, 20-3, and 20-4 is fixed to the four fixers 200 so that the baffle 1 is connected to the inner space of the fuel tank 100 And the fuel tank 100 is manufactured as a finished product having the baffle 1 as an internal space.
