Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は主として自動車等の燃料タンク内に配置され
るバッフルプレートに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention mainly relates to a baffle plate arranged in a fuel tank of an automobile or the like.
自動車等の燃料タンクにあっては、該燃料タンク内の
燃料に加速度が及ぼされることにより該燃料が流動し、
燃料タンク内壁に衝突して干渉音が発生することを防止
するために、内部にバッフルプレートが配置されてい
る。In a fuel tank of an automobile or the like, when the fuel in the fuel tank is accelerated, the fuel flows,
A baffle plate is disposed inside in order to prevent the collision noise from being generated by colliding with the inner wall of the fuel tank.
従来においては例えば第4図に示すように燃料タンク
(1)の内部に上壁から縦板状のバッフルプレート
(2),(2)を垂設した構成が提供されている。Conventionally, for example, as shown in FIG. 4, a structure in which vertical plate-shaped baffle plates (2) and (2) are vertically provided from an upper wall inside a fuel tank (1) is provided.

発生することは防止出来ない。However, in the above-mentioned conventional configuration, when the fuel (3) in the fuel tank (1) is accelerated and flows in the forward direction shown by the arrow in FIG. 4, the flow of the fuel (3) is caused by the front baffle. The baffle plate (2) is restrained by the plate (2), but at the same time, since the baffle plate (2) directly faces the flow of the fuel (3), the baffle plate (2) repels or flips up the fuel (3), and the baffle plate ( The fuel (3) colliding with the upper inner wall of the fuel tank (1) due to the rebound and rebound of the fuel (3) that wraps around on the back side of the fuel tank (1) by the front inner wall of the fuel tank (1) to generate an interference sound. Cannot be prevented.

料タンク(11)のバッフルプレート(12)を提供するも
のである。As a means for solving the above-mentioned conventional problems, the present invention is arranged in the front part of the fuel tank (11) and has a horizontal piece (12).
A baffle plate (12) for a fuel tank (11) having a cross section of A and a horizontal piece (12) A, a hanging piece (12) B hanging obliquely forward from a rear edge of the horizontal piece (12). is there.

片(12)Aによってはね返しやはね上がりが防止され、
したがって燃料タンク(11)の上内壁への燃料(13)の
衝突が防止される。The longitudinal flow of the fuel (13) in the fuel tank (11) is suppressed by the hanging piece (12) B of the baffle plate (12) having a vertical cross section. At this time, since the hanging piece (12) B hangs obliquely forward, the fuel (13) is directed obliquely downward, and splashing and rising are prevented. Further, the fuel (13) wrapping around on the back side of the baffle plate (12), that is, forward, is directed upward by the front inner wall of the fuel tank (11), but by the horizontal piece (12) A of the baffle plate (12). Prevents rebounds and splashes,
Therefore, the collision of the fuel (13) with the upper inner wall of the fuel tank (11) is prevented.
したがって本考案においては燃料タンク内の燃料の加
速度による流動にもとづく干渉音の発生は殆んど完全に
防止することが出来る。Therefore, in the present invention, the generation of the interference sound due to the flow of the fuel in the fuel tank due to the acceleration can be almost completely prevented.

部に溶接されている。The present invention will be described with reference to an embodiment shown in FIGS. 1 to 3, in which a baffle plate (12) is disposed in front of the inside of the fuel tank (11). The baffle plate (12) has a horizontal piece (12) A and a horizontal piece (12) A as shown in FIG.
Hanging piece (12) B hanging from the rear edge diagonally forward
And a plurality of communicating holes (12) C are provided in the hanging piece (12) B, and mounting portions (12) D are provided at the side edges. Baffle plate (12)
Is welded to the front portion of the inner wall of the fuel tank (11) through the attachment portion (12) D.

への衝突が防止される。In the above configuration, when the acceleration (starting, stopping, shifting, etc.) of the automobile affects the fuel (13) in the fuel tank (11), for example, when the acceleration is in the forward direction, the fuel (13) flows in the forward direction. However, as shown by the arrow in FIG. 3, the fuel (13) is directed obliquely downward by the hanging piece (12) B of the baffle plate (12), and the flow in the forward direction is suppressed. Then, it passes through the communication hole (12) C of the hanging piece (12) B of the baffle plate (12), or the baffle plate (12)
The fuel (13) sneaking from the lower side to the back side is directed upward by the front inner wall of the fuel tank (11), but the upward flow is suppressed by the horizontal piece (12) A of the baffle plate (12). And directed downward. Therefore the fuel tank (1
The fuel (13) in 1) is reliably prevented from bouncing upwards and splashing, and the fuel (13) is prevented from colliding with the upper inner wall of the fuel tank (11).
