Description

The assembly structure of the baffle and the baffle and the tank in which the baffle is assembled}

The present invention relates to a baffle assembly structure that increases the degree of freedom in the shape of the baffle and reduces cost and weight by applying a resin baffle to a metal tank, and to the baffle and the tank in which the baffle is assembled.

A baffle is installed inside the fuel tank to maintain rigidity and block noise caused by fuel flow.

A plurality of these baffles are installed inside the fuel tank to partition the internal space, and the fuel is divided into each partitioned space.

Additionally, a plurality of flow holes are formed in the middle of the baffle, allowing fuel divided into spaces to flow into other adjacent spaces through the flow holes.

Meanwhile, in the case of a fuel tank made of metal, the baffle is also formed of the same metal.

Accordingly, the baffle is fixed to the fuel tank using a method such as spot welding, so that the baffle is firmly fixed.

However, compared to plastic baffles, metal baffles have a lower degree of freedom of shape and have problems of increased weight and cost.

The matters described as background technology above are only for the purpose of improving understanding of the background of the present invention, and should not be taken as recognition that they correspond to prior art already known to those skilled in the art.

Figure 1 is a diagram showing the components for assembling the baffle 200 of the present invention separated into the tank 100, and Figure 2 is a diagram showing the baffle 200 assembled in the tank 100 according to the present invention. It is a drawing shown as seen from below, and FIG. 3 is a cross-sectional view along line A-A of FIG. 2.

Referring to the drawings, the baffle 200 assembly structure of the present invention includes a tank 100 formed of a metal material; A baffle 200 made of a resin material and having an assembly portion 210 formed toward the inner surface of the tank 100; A bush 300 made of a heat-resistant resin material and covered with the assembly part 210; and a fixing means having one end fixed to the tank 100 and the other end being mounted through the assembly portion 210 of the bush 300 and the baffle 200.

For example, a tank 100 containing fuel is formed by stacking an upper and lower plate made of steel, and a baffle 200 made of a resin material is assembled on the inner surface of the upper plate of the tank 100.

The assembly portion 210 of the baffle 200 assembled on the upper plate of the tank 100 is covered with a bush 300 made of heat-resistant resin, and the baffle 200 and the tank are connected by a fixing means with the bush 300 in between. (100) is fixed.

The baffle 200 may be made of plastic such as HDPE, and the bush 300 may be made of heat-resistant plastic such as PA66.

That is, by applying the baffle 200 made of a resin material to the tank 100 made of a metal material, the rigidity and freedom of shape of the baffle 200 are increased, as well as the weight and cost of the tank 100 are reduced.

However, when the baffle 200 is made of a resin material, the high temperature heat generated during the painting and drying process of the metal tank 100 may be transmitted to the baffle 200, causing damage to the baffle 200.

Accordingly, if the baffle 200 is made of a heat-resistant resin material, damage to the baffle 200 can be prevented, but the manufacturing cost of the baffle 200 increases.

Therefore, in the present invention, the entire baffle 200 is not formed of heat-resistant resin, but only the portion directly in contact with the tank 100 is assembled with the bush 300 of heat-resistant resin, thereby reducing product cost.

In addition, referring to FIG. 3, the fixing means is a welding bracket 400 whose upper end is formed in a branched shape and welded to the inner surface of the tank 100, and whose lower end is in close contact with the upper surface of the bush 300. ; A stud bolt 500 is fixed to the lower end of the welding bracket 400 and is provided through the bush 300 and the assembly portion 210; And a nut 600 fastened to the lower part of the stud bolt 500 penetrating the assembly part 210.

Specifically, the upper end of the welding bracket 400 is divided into several plate shapes and joined by welding in surface contact with the bottom of the upper plate of the tank 100.

Then, the upper end of the stud bolt 500 is fixed to the lower end of the welding bracket 400, and the stud bolt 500 penetrates the assembly portion 210 of the bush 300 and the baffle 200 to form the stud bolt 500. The lower end protrudes toward the lower end of the assembly unit 210.

Accordingly, the nut 600 is fastened to the bottom of the stud bolt 500 protruding from the bottom of the assembly portion 210, thereby assembling the resin baffle 200 to the metal tank 100.

Continuing with reference to FIG. 3, the assembly portion 210 is formed to protrude in the shape of a square pillar toward the upper plate of the tank 100; The bush 300 may be assembled in a shape that entirely covers the upper surface of the assembly unit 210.

That is, the assembly portion 210 is formed to protrude from the upper surface of the horizontal panel 250, which will be described later, and the bush 300 is assembled in a shape that entirely covers the upper surface of the assembly portion 210.

Accordingly, the welding bracket 400 is supported by only contacting the bush 300 without contacting the assembly part 210, thereby more reliably blocking heat generated in the tank 100 from being conducted to the baffle 200. .

Figure 4 is a diagram showing the state before the bush 300 according to the present invention is assembled to the assembly part 210, and Figure 5 is an enlarged view showing the top shape of the assembly part 210 according to the present invention.

Referring to the drawings, a flat support portion 220 is formed at the top of the assembly portion 210; Fitting hole portions 240 are formed in a cut shape at both edges of the support portion 220; Ring-shaped sliding fitting parts 310 are formed on both sides of the bush 300, so that the sliding fitting parts 310 can be fitted into the fitting hole 240 in a shape that surrounds both sides of the support part 220.

In addition, the sliding fitting part 310 can be assembled by sliding on both sides of the support part 220 along the longitudinal direction of the fitting hole part 240.

For example, a pillar portion forming the perimeter of the assembly unit 210 is formed to protrude from the upper surface of a horizontal panel 250, which will be described later, and a plate-shaped support portion 220 is formed at the top of the pillar portion.

In addition, among the four corners bordered by the top of the pillar portion and the edge of the support portion 220, a fitting hole portion 240 is formed at a pair of corners facing each other to fit the slide light fitting portion, and the remaining pair of corners are blocked. formed into a shape.

According to this configuration, the sliding fitting portion 310 formed on both sides of the bush 300 is aligned with one end of the fitting hole portion 240 formed on both sides of the support portion 220, and the opposite end of the fitting hole portion 240 is aligned. Push the bush (300) toward the part.

Then, the sliding fitting part 310 slides and fits along both sides of the support part 220 like a rail structure, allowing the bush 300 to be easily and conveniently assembled to the baffle 200.

In addition, one end of the fitting hole 240 into which the sliding fitting part 310 enters is formed in an open shape, and the other end of the fitting hole 240 is formed in a blocked shape to determine the position of the sliding fitting part 310. will be regulated.

That is, the front ends of the inserting hole portions on both sides 240 are open because the top of the column portion of the assembly portion 210 is formed in a groove shape, while the rear ends of the insertion hole portions on both sides 240 are opened at the top of the column portion of the assembly portion 210. It is formed in this closed shape and acts as a stopper.

Therefore, when the bush 300 slides from the front end of the fitting hole 240 toward the rear end, the end of the sliding fitting part 310 is blocked at the rear end of the fitting hole 240, thereby changing the assembly position of the bush 300. will be regulated.

In addition, Figure 6 is an enlarged view showing the bush 300 according to the present invention assembled to the assembly unit 210, and Figure 7 is a drawing showing the locking structure of the first and second locking protrusions 230 and 320 according to the present invention. This is a drawing showing.

Referring to the drawing, locking protrusions 230 and 320 are formed at the portions where the support portion 220 and the sliding fitting portion 310 face each other and are fitted to enable mutual locking of the bush 300 assembled to the assembly portion 210. Leaving can be prevented.

For example, first locking protrusions 230 of a wedge shape are formed on both sides of the support part 220, and second locking protrusions 320 of a hemispherical shape are formed on both inner surfaces of the sliding fitting part 310.

Therefore, in the process of sliding and fitting the sliding fitting portion 310 along the support portion 220, when the second locking protrusion 320 goes over the first locking protrusion 230, it is held by the first locking protrusion 230. By maintaining the locked state of the second locking protrusion 320, the bush 300 is prevented from being separated from the assembly portion 210.

Meanwhile, Figure 8 is a view of the baffle 200 of the present invention viewed from below.

Referring to the drawings, the baffle 200 includes a horizontal panel 250 with a flow hole 252 formed thereon; An outer rib 260 fixed in a shape surrounding the edge of the horizontal panel 250; A center rib 270 formed in a grid shape on the upper surface of the horizontal panel 250; A vertical panel 280 is formed with a flow hole 282 and is extended to a shape connected to the outer rib 260 and the center rib 270 on the bottom of the horizontal panel 250; And a reinforcing rib 290 formed in a shape perpendicular to the vertical panel 280 and the horizontal panel 250.

For example, center ribs 270 are formed at right angles in a lattice shape on the upper surface of the horizontal panel 250 surrounded by the outer ribs 260.

And, on the lower surface of the horizontal panel 250 corresponding to the center rib 270 and the outer rib 260, a vertical panel 280 is formed at right angles and is longer and downward than the outer rib 260, and is perpendicular to the horizontal panel 250. Reinforcing ribs 290 are formed in a perpendicular shape on the panel 280.

For reference, a plurality of flow holes 252 and 282 are formed in the horizontal panel 250 and the vertical panel 280.

In this way, the outer rib 260, the center rib 270, the vertical panel 280, and the reinforcing rib 290 are formed in an organic and solid manner centered on the horizontal panel 250, thereby forming the baffle 200. While minimizing the deformation of the baffle 200, the baffle 200's unique floating noise reduction function is implemented.

In addition, the vertical panel 280 is formed at a position corresponding to the outer rib 260 and the center rib 270 formed in the front and rear directions; The reinforcing rib 290 may be formed at a position corresponding to the center rib 270 formed in the left and right directions.

For example, among the outer ribs 260 surrounding the horizontal panel 250, the vertical panel 280 is formed at the lower portion of the outer rib 260 formed in the front-back direction on one side.

And, among the center ribs 270 formed on the upper surface of the horizontal panel 250, a vertical panel 280 is formed below the center rib 270 formed in the front-back direction.

In addition, among the center ribs 270 formed on the upper surface of the horizontal panel 250, a reinforcing rib 290 is formed at the lower part of the center rib 270 formed in the left and right directions, and the lower end of the reinforcing rib 290 is higher than the outer rib 260. ) can be formed to be the same as the height of the bottom.

In addition, the reinforcing rib 290 is formed connected to the vertical panel 280 and the horizontal panel 250; The reinforcing ribs 290 formed on the vertical panel 280 extend to the bottom of the vertical panel 280; The reinforcing rib 290 formed on the horizontal panel 250 may be formed to continue on the inner surface of the outer rib 260.

That is, the reinforcing rib 290 is connected to the inner surface of the outer rib 260 and is formed in a shape that continues continuously along the bottom of the horizontal panel 250 and the side of the vertical panel 280, thereby forming the horizontal panel 250 and By maintaining the rigidity of the vertical panel 280, deformation of the baffle 200 is prevented.

In addition, an assembly portion 210 may be formed in the middle of the center rib 270.

Accordingly, by securing the support rigidity of the assembly part 210, the baffle 200 can be more stably assembled to the tank 100.
