The specific embodiment
Below, with reference to accompanying drawing the Fuel Tank that embodiments of the present invention relate to is at length described.
With reference to Fig. 1, Fig. 2, the Fuel Tank in the present embodiment is described.
Fig. 1 is the birds-eye view of the Fuel Tank of embodiment, and Fig. 2 is that right abaft from the Fuel Tank of embodiment is to the block diagram of observing.
In addition, in the following description all around, in the vehicle when direction up and down is equipped on vehicle by Fuel Tank 1 all around, direction up and down represents.
Fuel Tank 1 shown in Figure 1 for example is resin, and is involutory at face of joint A place up and down, for example forms under the overlooking that the top plate portion 2 that formed by blow molding and base plate 3 consist of roughly the shape near rectangle.
As shown in Figure 2, base plate 3 has front face 3a, left side wall 3b, right side wall 3c, bottom surface 3e and forms.
As shown in Figure 1, although the central portion of rear surface 2d, the 3d of top plate portion 2 and base plate 3 is smooth on left and right directions, the left and right sides both wings of rear surface 2d, the 3d of top plate portion 2 and base plate 3 part is the plane center side under the overlooking of Fuel Tank 1 obliquely.
And, as shown in Figure 1 and Figure 2, the position from top to the edge of the front side of end face 2e of front face 2a at top plate portion 2 is provided with a plurality of recesses 5 continuously along left and right directions, these a plurality of recesses 5 are to the inboard of Fuel Tank 1 depression, and extend (corresponding with " recess is arranged on the boundary part of front face or rear surface and end face " in claims) along the fore-and-aft direction of vehicle.In the example of Fig. 1, the left and right section in the front side of top plate portion 2 is provided with respectively two recesses 5.
In addition, the position from top to the edge of the rear side of end face 2e of rear surface 2d at top plate portion 2 is provided with a plurality of recesses 5 continuously along left and right directions, these recesses 5 are to the inboard of Fuel Tank 1 depression, and extend (corresponding with " recess is arranged on the boundary part of front face or rear surface and end face " in claims) along the roughly fore-and-aft direction of vehicle.In the example of Fig. 1, be provided with two recesses 5 in the section of left wing of the rear side of top plate portion 2, be provided with three recesses 5 at the right wing part of the rear side of top plate portion 2.
The fore-and-aft direction cross section of this recess 5 is roughly semi-circular shape, and this recess 5 forms curved surface (with reference to Fig. 3) at left and right directions smoothly with the par 6 of par 6, front face 2a and the rear surface 2d of the edge of the end face 2e adjacent with its left and right sides.
And, recess 5 merges with the par 6 of front face 2a or rear surface 2d smoothly with the front and back wall side end 5a of recess 5, and the top surface side end 5b of recess 5 forms (with reference to Fig. 3 (a)) with the mode that merge the par 6 of the edge of the front side of end face 2e or rear side smoothly.Here, the front and back wall side end 5a of recess 5, top surface side end 5b and claims of recess 5 " both ends of the fore-and-aft direction of recess " put down in writing are corresponding.
In addition, bottom surface 3e is the plane of general planar.
As shown in Figure 2, be connected with fuel filler pipe 11, the Bas Discharged pipe 12 of common setting at Fuel Tank 1, and be provided with petrolift 13, Fuel switching valve 14, be connected with and the tank connected purification pipe 15 of not shown active carbon at Fuel switching valve 14.
In the example of Fig. 1, Fig. 2, the front side approximate half proportion by subtraction rear side of the top plate portion 2 of Fuel Tank 1 erects highly, and the central authorities at the top that this front side approximate half is divided are equipped with Fuel switching valve 14, thereby make fuel vapo(u)r to purification pipe 15 side flow.
In addition, the end face 2e general planar that the rear side approximate half of the top plate portion 2 of Fuel Tank 1 is divided, for the feature that prevents flat molding box is up and down sagging, for example the roughly left and right sides of petrolift 13 be provided with up and down weld part 8,8 in the direction position of leaving predetermined distance to the left and right from petrolift 13, up and down weld part 8,8 by make end face 2e and bottom surface 3e towards each other the interior side of Fuel Tank 1 be roughly cylindric and bloat and be welded.
Dispose this up and down the left and right directions in weld part 8,8 the Fuel Tank 1 the position for the position of the left and right directions of many recesses 5 that arrange at the position from top to the edge of the front side of end face 2e of front face 2a, and the position of staggering in nonoverlapping mode, the position of the left and right directions of many recesses 5 that arrange at the position from top to the edge of the rear side of end face 2e of rear surface 2d.That is, as shown in Figure 1, be the position of the central authorities of the right that partially keeps left.
Then, with reference to Fig. 3, to the fuel in the Fuel Tank 1 when the vehicle start sharp rearward mobile or during at vehicle stop the fuel in the Fuel Tank 1 forwards mobile and function recess 5 when with rear surface 2d, the 3d of Fuel Tank 1 or front face 2a, 3a collision occuring describes sharp.
Fig. 3 is the instruction diagram that flow of the recess with front face or rear surface of flowing of the rapid movement of the fuel in the Fuel Tank when occuring to collide, (a) being along the looking up obliquely upward of X-X arrow of Fig. 1 and the block diagram that obtains, (b) is that Y-Y in (a) is to looking cutaway view.
For example, use Fig. 3, the situation that collision occurs for the fuel when stopping in the Fuel Tank 1 and front face 2a, 3a describes as example.Even low and become in the situation of state of the liquid level that does not arrive front face 2a at the liquid level of fuel, if the fuel in the Fuel Tank 1 is forwards mobile sharp, then liquid level also can arrive front face 2a and collide with front face 2a, large mobile (collision sound) occurs to collide and produce with end face 2e in the bulk of the spittle that in the past, produced during this collision.Yet, according to present embodiment, as crest TW when wall 2a collides forward, because recess 5 stretches out to the inside, stretch out laterally the par 6 adjacent with the left and right sides of recess 5, therefore form level and smooth curved surface such shown in Fig. 3 (b) (smoothly sinuous curved surface) at left and right directions, separate like that to the left and right as shown by arrows with recess 5 flowing of occuring to collide, the position shown in the C of par 6 with collide from the mobile of opposition side.The part of the momentum of fuel is offset in the collision at the C place, position of flowing of this left and right directions, thereby the momentum that makes top with the front side edge of the end face 2e of top plate portion 2 or front face 2a that the fuel of collision occur reduces.Consequently, has the i.e. effect of mobile sound of the main tum that produces from end face 2e of mitigation.
And the number of recess 5 is more, more can produce flowing of more left and right directions at front face 2a, thereby the momentum forwards of larger fuel is offseted at position C place.That is, because recess 5 is a plurality of near formation on the overall width direction, therefore can make fuel to the left and right dispersion on the overall width direction that the certain width of collision occurs with recess 5.Consequently, the effect that relaxes the sound that flows is improved.
This effect at recess 5 places of rear surface 2d too.
Need to prove, dispose above-mentioned up and down weld part 8,8 by the roughly left and right sides at petrolift 13, thus at the central part that is equipped with weld part 8 up and down, 8 left and right directions of Fuel Tank 1, weld part 8,8 produces the effect of rocking of the fore-and-aft direction that suppresses fuel fully with petrolift 13 up and down, even therefore seldom, but for the minimizing of the fuel capacity that suppresses Fuel Tank 1, and recess 5 is not set.
In addition, because the top surface side end 5b of the front and back wall side end 5a of recess 5, recess 5 forms in the mode that merges smoothly with par 6, therefore say when moving up and down with respect to the liquid level of fuel or because of the flowing of fore-and-aft direction of the fuel that rocks generation of the fore-and-aft direction of fuel, can not produce at the 5b place, top surface side end of front and back wall side end 5a, recess 5 large mobile.
And, according to present embodiment, because recess 5 is to arrange (the boundary part that recess is arranged on front face or rear surface and end face) from the top of front face 2a to the edge of the front side of end face 2e or from the mode of top to the edge of the rear side of end face 2e of rear surface 2d, therefore consequently, the rigidity of the edge of the front side of end face 2e and the edge of rear side is improved.Thereby at fuel when mobile and its crest is patted the edge of front and back of end face 2e sharp to the front side of vehicle or rear side, the edge of the front and back by end face 2e has recess 5 and has and suppress the effect that end face 2e produces tum.
Then, with reference to Fig. 4, the left and right sides both wings part of rear surface 2d, 3d is consisted of mobile the inhibition of bringing towards the lower plane center side of overlooking of Fuel Tank 1 obliquely describe.Fig. 4 is the instruction diagram of the reaction wave when occuring to collide with rear surface that flows of the rapid movement of the fuel in the Fuel Tank.
As shown in Figure 4, for example in the situation that during vehicle start fuel mobile rearward sharp in Fuel Tank 1, crest is rearward mobile and collide with rear surface 2d like that shown in TW.The direction that flows that this generation is collided represents with thick arrow A C, AL, AR.Recess 5 places that are flowing in of thick arrow A L, AR collide shown in the arrow of CL, CR like that, the momentum that a forfeiture part flows.The such wave dissipation effect of Wave-dissipating block of Here it is seashore dykes and dams.Then, with respect to flowing of thick arrow A C, AL, AR, the reaction wave that is produced by rear surface 2d produces in such direction shown in hollow arrow RC, RL, the RR, and in the mutual interference in the regional B place of overlooking lower central authorities of Fuel Tank 1, the part of the momentum of reaction wave is offseted.Consequently, the mobile sound in the time of can relaxing reaction wave and front face 2a generation collision.
Especially in order to expect this effect, can expect the bottom surface 3e general planar of base plate 3, make the gait of march of reaction wave for hollow arrow RC, RL, RR, be roughly the same speed, thereby interfere at the regional B of central authorities.This be because, if bottom surface 3e is general planar and overlook the dark position of lower existence and shallow position not, then the speed of fluctuation makes the phase shifting of fluctuation accelerating when advance in shallow position from the dark position of bottom surface 3e, thereby does not work to the direction of eliminating fluctuation each other.
According to present embodiment, since recess 5 with from the top of front face 2a or top to the edge of the front side of end face 2e of rear surface 2d or the mode of the edge of rear side (edges of the front and back of end face 2e) (the boundary part that recess is arranged on front face or rear surface and end face) is set, therefore need not as the prior art of patent documentation 2, baffle plate to be set, thereby simple in structure, and the capacity that can reduce hardly Fuel Tank 1 just can relax the sound that flows.
In the present embodiment, Fuel Tank 1 be not limited to the end face 2e of top plate portion 2 forwardly side form to get high such mode, also can form on general planar ground.
In the situation of the Fuel Tank 1 of such platypelloid type, in order to ensure same fuel capacity, make the width of fore-and-aft direction of the Width of fore-and-aft direction of Fuel Tank 1 Fuel Tank 1 shown in Figure 1 large, thereby because of the miles of relative movement of rocking the ripple that causes elongated, the momentum that the fuel that collides occurs with many recesses 5 also becomes greatly, and therefore mobile the above-mentioned inhibition brought of many recesses 5 is higher than the situation of Fuel Tank shown in Figure 11.
In addition, in the Fuel Tank 1 of present embodiment, the bottom surface 3e general planar of base plate 3 ground forms, but also can form the shape that the saddle type disconnects in substantial middle punishment about like that.
In the present embodiment, Fuel Tank 1 is provided with a plurality of recesses 5 at the position from top to the edge of the front side of end face 2e of front face 2a of top plate portion 2 continuously along left and right directions, these a plurality of recesses 5 are to the inboard depression of Fuel Tank 1, and the fore-and-aft direction along vehicle extends, and the position from top to the edge of the rear side of end face 2e of rear surface 2d at top plate portion 2 is provided with a plurality of recesses 5 continuously along left and right directions, these a plurality of recesses 5 are to the inboard depression of Fuel Tank 1, and the roughly fore-and-aft direction along vehicle extends, but Fuel Tank 1 is not limited to this.
Fuel Tank 1 can also constitute, only along left and right directions a plurality of recesses 5 are set continuously from the position of top to the edge of the front side of end face 2e of front face 2a and the side from top to the position of the edge of the rear side of end face 2e of rear surface 2d of top plate portion 2 at top plate portion 2, these a plurality of recesses 5 cave in to the inboard of Fuel Tank 1, and extend along the roughly fore-and-aft direction of vehicle.
And in the present embodiment, the left and right sides both wings of the top plate portion 2 of Fuel Tank 1 and rear surface 2d, the 3d of base plate 3 part is the plane center side under the overlooking of Fuel Tank 1 obliquely, but Fuel Tank 1 is not limited to this.Fuel Tank 1 can constitute the left and right sides both wings part plane center side under the overlooking of Fuel Tank 1 obliquely of front face 2a, the 3a of top plate portion 2 and base plate 3.
