Detailed description of the invention
Below, with reference to accompanying drawing, the Fuel Tank that embodiments of the present invention relate to is described in detail.
With reference to Fig. 1, Fig. 2, the Fuel Tank in present embodiment is described.
Fig. 1 is the birds-eye view of the Fuel Tank of embodiment, and Fig. 2 is from the right abaft of the Fuel Tank of embodiment to the block diagram observed.
In addition, in the following description all around, in the vehicle of upper and lower direction when being equipped on vehicle by Fuel Tank 1 all around, upper and lower direction represents.
Fuel Tank 1 shown in Fig. 1 is such as resin-made, involutory at face of joint A place up and down, such as, be formed as the shape of approximately rectangle under the overlooking be made up of the top plate portion 2 of blow molding and base plate 3.
Top plate portion 2 has front face 2a, left side wall 2b, right side wall 2c, end face 2e and form.
As shown in Figure 2, base plate 3 has front face 3a, left side wall 3b, right side wall 3c, bottom surface 3e and form.
As shown in Figure 1, although the central portion of rear surface 2d, 3d of top plate portion 2 and base plate 3 is smooth in the lateral direction, the left and right both wings part of rear surface 2d, 3d of top plate portion 2 and the base plate 3 plane central side obliquely under the overlooking of Fuel Tank 1.
And, as shown in Figure 1 and Figure 2, multiple recess 5 is provided with continuously from the top of front face 2a to the position of the edge of the front side of end face 2e along left and right directions at top plate portion 2, this multiple recess 5 caves in the inner side of Fuel Tank 1, and extends (corresponding with " recess is arranged on the junction section of front face or rear surface and end face " in claims) along the fore-and-aft direction of vehicle.In the example in fig 1, two recesses 5 are respectively equipped with in the left and right portion of the front side of top plate portion 2.
In addition, multiple recess 5 is provided with continuously from the top of rear surface 2d to the position of the edge of the rear side of end face 2e along left and right directions at top plate portion 2, these recesses 5 cave in the inner side of Fuel Tank 1, and extend (corresponding with " recess is arranged on the junction section of front face or rear surface and end face " in claims) along the roughly fore-and-aft direction of vehicle.In the example in fig 1, be provided with two recesses 5 in the 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 in roughly semi-circular shape, and the par 6 of edge, the par 6 of front face 2a and rear surface 2d of this recess 5 and the end face 2e adjacent with its left and right form curved surface (reference Fig. 3) smoothly in the lateral direction.
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 mode that the top surface side end 5b of recess 5 merges with the par 6 of the front side of end face 2e or the edge of rear side is smoothly formed (with reference to Fig. 3 (a)).Here, the top surface side end 5b of the front and back wall side end 5a of recess 5, recess 5 is corresponding with " both ends of the fore-and-aft direction of recess " described in claims.
In addition, bottom surface 3e is the plane of general planar.
As shown in Figure 2, Fuel Tank 1 is connected with the fuel filler pipe 11, the air discharge pipe 12 that usually arrange, and is provided with petrolift 13, Fuel switching valve 14, Fuel switching valve 14 is connected with the tank connected purification pipe 15 with not shown active carbon.
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 high, is equipped with Fuel switching valve 14 in the central authorities at the top that this front side approximate half is divided, thus fuel vapo(u)r is moved to purification pipe 15 effluent.
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, in order to prevent the feature of flat molding box and upper and lower sagging, be provided with upper and lower weld part 8,8 such as in the roughly left and right sides of petrolift 13 from the position that petrolift 13 leaves predetermined distance in the lateral direction, this upper and lower weld part 8,8 by make end face 2e and bottom surface 3e towards each other in Fuel Tank 1 side bloat in roughly cylindric and be welded.
The position being configured with the left and right directions in the Fuel Tank 1 of this upper and lower weld part 8,8 is the position staggered in nonoverlapping mode in the position of the left and right directions of many recesses 5 arranged with the position in top to the edge of the front side of end face 2e from front face 2a and the position of the left and right directions of many recesses 5 that arranges at the position of top to the edge of the rear side of end face 2e from rear surface 2d.That is, as shown in Figure 1, be the position of the central authorities of the right direction that partially keeps left.
Then, with reference to Fig. 3, the fuel in the Fuel Tank 1 when vehicle start is rearward moved sharp or fuel when vehicle stops in Fuel Tank 1 forwards move sharp and and the function of recess 5 that occurs when colliding of rear surface 2d, 3d of Fuel Tank 1 or front face 2a, 3a be described.
Fig. 3 is the instruction diagram that flowing when colliding occurs for the flowing of sharply movement of fuel in Fuel Tank and the recess of front face or rear surface, a () is looking up obliquely upward of X-X arrow along Fig. 1 and the block diagram obtained, (b) is that Y-Y in (a) is to looking cutaway view.
Such as, use Fig. 3, the situation that fuel during to stop in Fuel Tank 1 and front face 2a, 3a occur to collide is described.Even if low and when becoming the state of the liquid level not arriving front face 2a at the liquid level of fuel, if the fuel in Fuel Tank 1 forwards moves sharp, then liquid level also can arrive front face 2a and collide with front face 2a, in the past, the bulk of the spittle produced during this collision and end face 2e occur collide and produce large flowing sound (collision sound).But, according to the present embodiment, when wall 2a collides crest TW forward, because recess 5 stretches out to the inside, the par 6 adjacent with the left and right of recess 5 is stretched out laterally, form level and smooth curved surface (smoothly sinuous curved surface) such shown in Fig. 3 (b) in the lateral direction, the flowing therefore occurring to collide with recess 5 separates as shown by the arrows to the left and right, and the position shown in the C in par 6 is collided with the flowing from opposition side.A part for the momentum of fuel is offset by the collision at the C place, position of the flowing of this left and right directions, thus the momentum that the fuel collided occurs with the front side edge of the end face 2e of top plate portion 2 or the top of front face 2a is reduced.Consequently, there is the effect relaxing tum and the flowing sound mainly produced from end face 2e.
Further, the number of recess 5 is more, more can produce the flowing of more left and right directions on front face 2a, thus the momentum forwards of larger fuel can be made to offset at C place, position.That is, because recess 5 is multiple close to being formed on overall width direction, therefore, it is possible to make the fuel that the one fixed width of colliding occurs with recess 5 disperse to the left and right on overall width direction.Consequently, the effect of mitigation flowing sound is made to improve.
This effect at recess 5 place of rear surface 2d too.
It should be noted that, by being configured with above-mentioned weld part up and down 8,8 in the roughly left and right sides of petrolift 13, thus at the central part being equipped with the left and right directions of upper and lower weld part 8,8 of Fuel Tank 1, upper and lower weld part 8,8 produces the effect of rocking suppressing the fore-and-aft direction of fuel fully together with petrolift 13, even if therefore little, but in order to suppress the minimizing of the fuel capacity of Fuel Tank 1, and recess 5 is not set.
In addition, because the front and back wall side end 5a of recess 5, the top surface side end 5b of recess 5 are formed in the mode merged smoothly with par 6, when therefore moving up and down relative to the liquid level of fuel or because of the fore-and-aft direction of fuel the flowing of rocking the fore-and-aft direction of the fuel of generation for, large flowing sound can not be produced at the 5b place, top surface side end of front and back wall side end 5a, recess 5.
And, according to the present embodiment, because recess 5 is to arrange (junction section that recess is arranged on front face or rear surface and end face) from the mode of the edge of top to the front side of end face 2e of front face 2a or the top from rear surface 2d to the edge of the rear side of end face 2e, therefore consequently, the rigidity of the edge of the front side of end face 2e and the edge of rear side is improved.Thus, fuel to the front side of vehicle or rear side move sharp and its crest pats the edge of the front and back of end face 2e time, by the edge of the front and back of end face 2e, there is recess 5 and there is the effect suppressing end face 2e to produce tum.
Then, with reference to Fig. 4, the inhibition left and right both wings part of rear surface 2d, 3d plane central side obliquely under the overlooking of Fuel Tank 1 being formed to the flowing sound brought is described.Fig. 4 is the instruction diagram that reaction wave when colliding occurs for the flowing of the sharply movement of fuel in Fuel Tank and rear surface.
As shown in Figure 4, such as, when vehicle start, fuel moves rearward sharp in Fuel Tank 1, as shown in TW, crest rearward moves and collides with rear surface 2d.The thick arrow A C in direction of the flowing this collided, AL, AR represent.Recess 5 place that is flowing in of thick arrow A L, AR collides as shown in the arrow of CL, CR, loses the momentum of part flowing.The wave dissipation effect that the Wave-dissipating block of Here it is seashore dykes and dams is such.Then, relative to the flowing of thick arrow A C, AL, AR, the reaction wave produced by rear surface 2d produces on direction such shown in hollow arrow RC, RL, RR, and the B place, region of central authorities under the overlooking of Fuel Tank 1 interferes mutually, and a part for the momentum of reaction wave is offseted.Consequently, the flowing sound that reaction wave and front face 2a occur when colliding can be relaxed.
Especially in order to expect this effect, the bottom surface 3e general planar of base plate 3 can be expected, making the gait of march of reaction wave be roughly the same speed for hollow arrow RC, RL, RR, thus interfering at the region B of central authorities.This be due to, if bottom surface 3e not general planar and overlook the dark position of lower existence and shallow position, the speed then fluctuated accelerates when advancing to shallow position in the position dark from bottom surface 3e and makes the phase shifting of fluctuation, thus does not work to the direction of the fluctuation eliminated each other.
According to the present embodiment, because recess 5 is arranged (junction section that recess is arranged on front face or rear surface and end face) in the mode of the edge (edges of the front and back of end face 2e) from the top on the top of front face 2a or rear surface 2d to the edge of the front side of end face 2e or rear side, therefore baffle plate is set without the need to the prior art as patent documentation 2, thus structure is simple, and the capacity reducing Fuel Tank 1 hardly just can relax flowing sound.
In the present embodiment, Fuel Tank 1 is not limited to and the end face 2e of top plate portion 2 is formed to obtain high such mode at front side, also can be formed on general planar ground.
When Fuel Tank 1 of such platypelloid type, in order to ensure same fuel capacity, make the width of the fore-and-aft direction of Fuel Tank 1 larger than the width of the fore-and-aft direction of the Fuel Tank 1 shown in Fig. 1, thus because of the miles of relative movement of rocking the ripple caused elongated, the momentum that the fuel collided occurs with many recesses 5 also becomes large, and therefore the inhibition of above-mentioned flowing sound brought of many recesses 5 is higher than the situation of the Fuel Tank 1 shown in Fig. 1.
In addition, in the Fuel Tank 1 of present embodiment, the bottom surface 3e general planar ground of base plate 3 is formed, but also can be formed as the saddle shape that disconnects in substantial middle punishment of left and right like that.
In the present embodiment, Fuel Tank 1 is provided with multiple recess 5 at top plate portion 2 continuously from the top of front face 2a to the position of the edge of the front side of end face 2e along left and right directions, this multiple recess 5 caves in the inner side of Fuel Tank 1, and extend along the fore-and-aft direction of vehicle, and be provided with multiple recess 5 at top plate portion 2 continuously from the top of rear surface 2d to the position of the edge of the rear side of end face 2e along left and right directions, this multiple recess 5 caves in the inner side of Fuel Tank 1, and extend along the roughly fore-and-aft direction of vehicle, but Fuel Tank 1 is not limited thereto.
Fuel Tank 1 can also be configured to, a side only the position of the position of top to the edge of the front side of end face 2e from front face 2a of top plate portion 2 and top to the edge of the rear side of end face 2e from rear surface 2d of top plate portion 2 arranges multiple recess 5 continuously along left and right directions, this multiple recess 5 caves in the inner side of Fuel Tank 1, and extends along the roughly fore-and-aft direction of vehicle.
Further, in the present embodiment, the left and right both wings part of the top plate portion 2 of Fuel Tank 1 and rear surface 2d, 3d of the base plate 3 plane central side obliquely under the overlooking of Fuel Tank 1, but Fuel Tank 1 is not limited thereto.The plane central side of the left and right both wings part that Fuel Tank 1 can be configured to front face 2a, 3a of top plate portion 2 and base plate 3 obliquely under the overlooking of Fuel Tank 1.
