本考案は波消板構造体を内臓せる車輛用燃料タ
ンクに係る。[Detailed Description of the Invention] The present invention relates to a vehicle fuel tank incorporating a wave-dissipating plate structure.
車輛用燃料タンク内には車輛走行時における燃
料の波動によつて生ずる、所謂パシヤ音を防止す
るための波消板が設けられている。 A wave-dissipating plate is provided in a vehicle fuel tank to prevent so-called pulsation noise caused by wave motion of fuel when the vehicle is running.
この波消板は通常燃料タンク本体と同様、鋼板
で形成され、短尺の帯鋼板を適宜横曲げし穿孔し
たものをタンク内を仕切るように配し、タンクへ
の取付手段として上記鋼板製波消板の上縁から複
数の耳片を出し、該各耳片をタンク天板へスポツ
ト溶接付けし一体化するという構造を採つてい
る。 This wave-dissipating plate is usually made of a steel plate, similar to the fuel tank body, and is made of short steel strips with appropriate horizontal bends and holes, arranged so as to partition the inside of the tank, and used as a means of attachment to the tank. A structure is adopted in which a plurality of lug pieces are protruded from the upper edge of the plate, and each lug piece is spot-welded to the tank top plate and integrated.
然しながら、タンク自身が鋼板製である上に、
タンク内部の主要構造体たる波消板を鋼板製とす
ると、全体として可成りの高重量物となり、車輛
の軽量化に逆行することとなる。 However, the tank itself is made of steel plate, and
If the wave-dissipating plate, which is the main structure inside the tank, is made of steel, the whole will be quite heavy, which goes against the weight reduction of the vehicle.
加えてスポツト溶接の如き点付けでは波消板へ
タンク内燃料の強い波動が繰り返し加わると溶接
個所が破断し、波消板がタンク内で遊離してしま
う恐れがあり、タンク損傷の原因ともなる等の欠
点があり、これらの事情も遠因となつて主として
工程削減、コスト低減化等の要求からそのスポツ
トレス化が希求されるに至つている。 In addition, when spot welding such as spot welding is used, if strong waves from the fuel in the tank are repeatedly applied to the wave-dissipating plate, the welded area may break and the wave-dissipating plate may become loose within the tank, causing damage to the tank. These disadvantages are also a contributing factor, and there has been a demand for spotless production, mainly due to demands for process reduction and cost reduction.
本考案はこれらの事情を背景として創案された
ものであつて、波消板の鋼板化を排し、加えてそ
のタンク内組込に際しての完全スポツトレス化を
達成せんとするものである。 The present invention was devised against these circumstances, and aims to eliminate the use of steel plates for the wave-dissipating plates, and also to achieve complete spot-free installation of the wave-dissipating plates in the tank.
以下本考案を図示の実施例に基いて詳述する。 The present invention will be explained in detail below based on the illustrated embodiments.

る。 In the figure, 1 indicates a fuel tank body for a vehicle. The fuel tank body 1 is made of a steel plate and consists of an upper split tank 2 and a lower split tank 3 which are divided into upper and lower parts at the middle part, and flanges 2a and 3a are respectively protruded from the periphery of the split opening of the upper and lower split tanks. A split tank structure is formed in which both flanges are overlapped and integrally closed by tightening bolts using the mounting holes 11 drilled in each flange.

数の波形曲板部６とから成る摺曲板構造とする。 In the figure, reference numeral 4 indicates a synthetic resin wave plate structure made of the above-mentioned integrally molded product. As shown in the figure, the shape of the wave plate structure 4 includes a base plate 5 fixed to the inner surface of the bottom plate of the lower split tank 3, and an inverted U-shape connected to the base plate 5 and directed toward the top plate of the upper split tank. It has a sliding curved plate structure consisting of a plurality of raised waveform curved plate parts 6.

ける弾性的な撓みを伴ないつつその復元力に抗し
上下割タンク間に挟持する構造とする。 The wave-dissipating plate structure 4 is interposed between the upper split tank 2 and the lower split tank 3, its base plate 5 is supported on the inner surface of the bottom plate of the lower split tank 3, and the top surface 6a of the wave-shaped curved plate portion 6 is supported. is supported by pressure on the inner surface of the top plate of the upper split tank 2, and due to the pressure, the sliding portion of the wave-dissipating plate structure 4 is elastically bent, resisting the restoring force, and held between the upper and lower split tanks. The structure is as follows.
前記の如く波消板構造体４は合成樹脂製の摺曲

によつて波形曲板部６を開かせる方向（摺曲方
向）へ弾性的に変形させ、該変形に伴なう上下方
向の反発力の発生にてガタのない保持を可能とし
ている。 As mentioned above, the wave-dissipating plate structure 4 is composed of a sliding curved plate structure made of synthetic resin, and when a strong pressing force is applied from above, the wave-dissipating plate structure 4 is elastically moved in the direction in which the wave-shaped curved plate portion 6 is opened (sliding direction). By deforming and generating a repulsive force in the vertical direction due to the deformation, it is possible to hold it without wobbling.

弾性効果をより良好なものとする。 The above-mentioned waveform curved plate part 6 has its left and right side surfaces inclined so as to widen toward the lower end, and has a gently sloping surface 6c at the raised base, and a waist-bending part is formed at the upper end of the sloping surface 6c, so that a pressing force is applied to the top surface. To improve the bending elastic effect in the vertical direction when working.

吸収する構成とする。 In the illustrated embodiment, upwardly curved plate portions 5a are formed at both left and right ends of the wave-dissipating plate structure 4 in the sliding direction, as shown in FIG. The upwardly curved plate part 5a is applied to the left-right arc-shaped corner part 3b of the lower tank 3, and this is used as a receiver when the pressing force is applied to the top part 6a and the corrugated curved plate part 6 is elastically deformed in the opening direction. While allowing the warped plate portion 5a to rise slightly along the arc-shaped corner portion 3b when pressure is applied, it is strongly pressed against the corner forming surface and its elastic force exerts a tensioning effect on the entire structure against the tank wall. The structure is designed to absorb the looseness that occurs in the left and right directions.

Both end surfaces of the wave-shaped curved plate portion 6 are brought into contact with the front-rear wall surface of the fuel tank 1 by engaging the beads 2b in the same direction or by using the bead 2b in the same direction. To make the rattling prevention effect more accurate.

A swirl tank 9 is used as a structural member inside the tank. Further, all or the main parts of the tank internal structural members are integrally molded, such as by integrally molding the air reservoir 10 with the swirling tank 9, to form the wave-dissipating plate structure 4.

The wave-dissipating plate is constructed by adopting an assembly structure in which a plurality of wave-shaped curved plate parts are made up of a synthetic resin molded product in an inverted U-shape, and this is held down by closing the above-mentioned upper and lower divided tanks. It becomes possible to install the structure without rattling (vibration caused by running), and it is possible to eliminate spot welding in conventional steel wave breakers, achieving a so-called spotless structure.
