Description

本発明は、エンジンのオイルパン内に貯留されているオイルの油量レベルを視認するエンジンの油量点検窓に関する。   The present invention relates to an engine oil amount inspection window for visually recognizing an oil amount level of oil stored in an engine oil pan.

車両に搭載されるエンジンでは、エンジンの稼動を良好に維持するために、オイルパン内の油量を確認する構造が装備されている。その多くは、サーベル状のオイルレベルゲージを用いて、オイルパン内のオイルの油量を確認する構造が用いられている。
ところが、油量の確認は、その都度、オイルパンから延びているオイルレベルガイドパイプ内に収めたオイルレベルゲージを抜き出し、オイルレベルゲージの先端部におけるオイルの濡れ具合を目視する作業で行なわれる。特に適正に油量を確認するためには、一回、オイルレベルゲージをオイルレベルガイドパイプから引き抜いて、先端に付いているオイルをウェスなどで拭き取ってから、オイルレベルゲージをオイルレベルガイドパイプに差込み、再びオイルレベルゲージをオイルレベルガイドパイプから引き抜いて、オイルレベルゲージ先端におけるオイルの濡れ具合を目視し、オイルの付着した部分が油量レベルの上限値〜下限値内に有るか否かで判定する。このため、油量の確認は、かなり面倒な作業となる。 The engine mounted on the vehicle is equipped with a structure for checking the amount of oil in the oil pan in order to maintain the engine operation satisfactorily. Many of them use a structure that checks the amount of oil in the oil pan using a saber-shaped oil level gauge.
However, each time the amount of oil is confirmed, the oil level gauge stored in the oil level guide pipe extending from the oil pan is extracted and the wetness of the oil at the tip of the oil level gauge is visually checked. To check the oil level properly, pull out the oil level gauge from the oil level guide pipe once, wipe off the oil on the tip with a waste cloth, and then attach the oil level gauge to the oil level guide pipe. Insert the oil level gauge again from the oil level guide pipe, visually check the oil wetness at the tip of the oil level gauge, and check whether the oil-attached part is within the upper limit value to the lower limit value of the oil level. judge. For this reason, checking the amount of oil is a rather troublesome task.

そこで、容易にオイルパン内の油量の視認が行なえるよう、エンジン本体に油量を確認する油量点検窓を設ける技術が提案されている。
こうした油量点検窓には、特許文献１に開示されているようにオイルパンに、透明な合成樹脂部材で形成したパイプを縦向きに取り付けて、オイルパン内のオイルを導き、このパイプに、点検用開口部やレベルマークを形成したカバーを設ける構造や、特許文献２に開示されているようにエンジン本体の側部に油量確認用の本体部品、ボディを取り付け、このボディの内部にオイルパン内と連通する連通室を形成し、この連通室の一部に窓部を設ける構造がある。
実開平２−１８６０６号公報 特開２０００−２８２８３７号公報 In view of this, a technique has been proposed in which an oil amount inspection window for confirming the oil amount is provided in the engine body so that the oil amount in the oil pan can be easily recognized.
In such an oil amount inspection window, as disclosed in Patent Document 1, a pipe formed of a transparent synthetic resin member is vertically attached to the oil pan, and the oil in the oil pan is guided to this pipe. A structure in which an inspection opening and a cover with a level mark are provided, or as disclosed in Patent Document 2, a body part and body for oil amount confirmation are attached to the side of the engine body, and oil is placed inside the body. There is a structure in which a communication chamber communicating with the inside of the pan is formed, and a window portion is provided in a part of the communication chamber.

ところが、いずれの油量点検窓も、多くの部品や通路を形成する構造で始めて、オイルパン内の油量を外部から目視する構造なので、かなり構造的に複雑である。このため、同点検窓の設置は、エンジンの組立工数やエンジンのコストに影響を与えやすく、改善が求められている。
そこで、本発明の目的は、簡単な構造で、容易にオイルパン内の油量の視認が行なえるエンジンの油量点検窓を提供することにある。 However, each of the oil amount inspection windows starts with a structure that forms many parts and passages, and has a structure in which the amount of oil in the oil pan is visually observed from the outside. For this reason, the installation of the inspection window tends to affect the number of engine assembly steps and the engine cost, and improvement is required.
SUMMARY OF THE INVENTION An object of the present invention is to provide an engine oil amount check window for an engine that can easily recognize the amount of oil in an oil pan with a simple structure.

請求項１に記載の発明は、上記目的を達成するために、オイルパンの側壁に孔部を設け、この孔部を塞ぐように側壁に、油量レベル確認用のレベルマークをもつ透視プレート部材を接着して、油量点検窓を構成した。
同構成により、簡単な構造で、外部からオイルパンの油量の視認が行える。
請求項２に記載の発明は、さらにエンジンの運転で振動しやすい板金製のオイルパンにおいては、オイル油量点検窓が共振するのを抑えるよう、オイルパンが板金製のときは、孔部および透視部材が配置されるオイルパンの側壁部分は、剛性強度を高めるべく、オイルパンの内側へ凹ませた凹部又は外側へ突き出した凸部で形成されることとした。 In order to achieve the above object, the first aspect of the present invention provides a see-through plate member having a hole in the side wall of the oil pan and a level mark for checking the oil level on the side wall so as to close the hole. Were bonded to form an oil amount inspection window.
With this configuration, the oil amount of the oil pan can be visually confirmed from the outside with a simple structure.
According to the second aspect of the present invention, in the oil pan made of sheet metal that is easily vibrated by the operation of the engine, when the oil pan is made of sheet metal, the hole portion and The side wall portion of the oil pan in which the see-through member is arranged is formed by a concave portion recessed inward of the oil pan or a convex portion protruding outward in order to increase the rigidity strength.

請求項３に記載の発明は、さらに、一層、油量点検窓が配置される側壁部分がオイルパンの振動に影響されない構造とするよう、凹部又は前記凸部の周りのオイルパンの側壁には、当該凹部又は凸部の剛性強度を高めるための補強ビードを形成することとした。   The invention according to claim 3 further has a structure in which the side wall portion on which the oil amount inspection window is arranged is not affected by the vibration of the oil pan on the side wall of the oil pan around the concave portion or the convex portion. The reinforcing beads for increasing the rigidity strength of the concave portion or the convex portion are formed.

請求項１の発明によれば、油量点検窓は、オイルパンの側壁に孔部を形成し、この孔部を塞ぐように透視プレート部材を接着するだけの構造ですみ、簡単な構造で、容易にオイルパン内の油量の視認が行なえる。
請求項２の発明によれば、エンジンの運転で振動しやすい板金製のオイルパンの場合、油量点検窓を設置する側壁部分に、オイルパンの内側へ凹ませた凹部又は外側へ突き出した凸部を形成することにより、当該側壁部分の剛性強度が高められ、油量点検窓が共振するのが抑えられる。 According to the invention of claim 1, the oil amount inspection window has a simple structure in which a hole is formed in the side wall of the oil pan and the fluoroscopic plate member is bonded so as to close the hole. The amount of oil in the oil pan can be easily seen.
According to the invention of claim 2, in the case of a sheet metal oil pan that easily vibrates during operation of the engine, the side wall portion on which the oil amount inspection window is installed has a recess recessed inward of the oil pan or a protrusion protruding outward. By forming the portion, the rigidity strength of the side wall portion is increased, and the oil amount inspection window is prevented from resonating.

それ故、透視プレート部材の剥がれが抑えられ、信頼性の有る油量点検窓が提供できる。
請求項３の発明によれば、補強ビードがもたらす剛性強度により、一層、油量点検窓が配置される側壁部分が、オイルパンに伝わる振動で影響されにくくなり、一層、振動しやすい板金製のオイルパンに適した油量点検窓を得ることができる。 Therefore, peeling of the fluoroscopic plate member is suppressed, and a reliable oil amount inspection window can be provided.
According to the invention of claim 3, due to the rigidity strength provided by the reinforcing bead, the side wall portion on which the oil amount inspection window is arranged is further less affected by the vibration transmitted to the oil pan, and is made of a sheet metal that is more easily vibrated. An oil amount inspection window suitable for an oil pan can be obtained.

以下、本発明を図１〜図３に示す第１の実施形態にもとづいて説明する。
図１は、エンジン、例えば内燃エンジンの一部を示している。同図１中１は、例えばレシプロ式のエンジン本体を構成するシリンダブロック、２は同シリンダブロック１の下部に組み付くオイルパンである。
オイルパン２は、例えば板金部材を略箱形に成形した板金製で、内部にはオイル（エンジンの各部の潤滑や冷却などを行なうもの）を貯留する貯留室３が形成してある。 The present invention will be described below based on the first embodiment shown in FIGS.
FIG. 1 shows a part of an engine, for example an internal combustion engine. In FIG. 1, reference numeral 1 denotes, for example, a cylinder block constituting a reciprocating engine main body, and reference numeral 2 denotes an oil pan assembled to the lower portion of the cylinder block 1.
The oil pan 2 is made of, for example, a sheet metal in which a sheet metal member is formed in a substantially box shape, and a storage chamber 3 for storing oil (which performs lubrication and cooling of each part of the engine) is formed inside.

このオイルパン２の側壁、例えば片側の側壁２ａの上部には、オイルの油量を視認するための油量点検窓５が設けられている。図２にはこの油量点検窓５の各部の構造が示され、図３には油量点検窓５の断面図（図２中のＡ−Ａ線に沿う断面）が示されている。
油量点検窓５は、図２（ａ）に示されるようにオイルパン２の側壁２ａの上部のうち、オイルパン２で定められた油量レベルの上限〜下限間に臨んでいる側壁部分２ｃの一部に通孔、例えば円形の孔部６を設け、図２（ａ）および図３に示されるようにこの孔部６の両側から孔部６の開口を塞ぐように、透視プレート部材、例えば透明な剛性樹脂部材で形成された２枚の円形の透明樹脂プレート７ａ，７ｂを、接着剤（図示しない）で、側壁部分２ｃの壁面にそれぞれ接着した構造で構成されている。透明樹脂プレート７ａ，７ｂのうち、例えば側壁２ａの外側の壁面に接着されている透明樹脂プレート７ａの板面には、図２（ａ），（ｂ）に示されるようにオイルパン２内の油量レベルを確認するためのレベルマーク、例えば貯留された油量の上限値を示す上限値ライン８ａと下限値を示す下限値ライン８ｂが設けられている。これにより、オイルパン２の外側から、オイルパン２内のオイルの油量が、透視樹脂プレート７ａ，７ｂを通じて、目視により、定められた上限値ライン８ａ〜下限値ライン８ｂ内に有るか否かが判るようにしている。なお、接着剤には、透明樹脂プレート７ａ，７ｂと側壁２間で高いシール性が確保されるよう、耐油性に優れた接着剤が用いてある。 An oil amount inspection window 5 for visually confirming the amount of oil is provided on the side wall of the oil pan 2, for example, on the upper side of the side wall 2a on one side. FIG. 2 shows the structure of each part of the oil amount inspection window 5, and FIG. 3 shows a cross-sectional view of the oil amount inspection window 5 (cross section taken along line AA in FIG. 2).
As shown in FIG. 2A, the oil amount inspection window 5 is a side wall portion 2c that faces between the upper limit and the lower limit of the oil amount level determined by the oil pan 2 in the upper part of the side wall 2a of the oil pan 2. A through-hole, for example, a circular hole 6, and a see-through plate member so as to close the opening of the hole 6 from both sides of the hole 6 as shown in FIG. 2 (a) and FIG. For example, two circular transparent resin plates 7a and 7b formed of a transparent rigid resin member are respectively bonded to the wall surface of the side wall portion 2c with an adhesive (not shown). Of the transparent resin plates 7a and 7b, for example, the plate surface of the transparent resin plate 7a bonded to the outer wall surface of the side wall 2a is provided inside the oil pan 2 as shown in FIGS. 2 (a) and 2 (b). Level marks for confirming the oil amount level, for example, an upper limit value line 8a indicating the upper limit value of the stored oil amount and a lower limit value line 8b indicating the lower limit value are provided. Thereby, from the outside of the oil pan 2, whether or not the amount of oil in the oil pan 2 is visually within the determined upper limit value line 8a to lower limit value line 8b through the transparent resin plates 7a and 7b. To understand. In addition, the adhesive agent excellent in oil resistance is used for the adhesive agent so that high sealing performance may be ensured between the transparent resin plates 7a and 7b and the side wall 2.

このように構成された油量点検窓５によると、オイルパン２内の油量を確認するときは、外部から透明樹脂プレート７ａ，７ｂを通じ、オイルパン２内に貯留されたオイルの油面位置を視認して、規定の油量範囲内であることを確認すればよく、容易、すなわち一目で、オイルパン２内の油量の視認ができる。
しかも、油量点検窓５は、オイルパン２の側壁２ａに形成した孔部６を塞ぐよう透視樹脂プレート７ａ、７ｂを側壁２ａに接着するだけでよく、簡単な構造ですみ、エンジンの組立工数やエンジンのコストへの影響も抑えられる。 According to the oil amount inspection window 5 configured in this way, when the amount of oil in the oil pan 2 is confirmed, the oil level position of the oil stored in the oil pan 2 from the outside through the transparent resin plates 7a and 7b. The amount of oil in the oil pan 2 can be easily recognized at a glance.
In addition, the oil amount inspection window 5 has only a simple structure, and only needs to be bonded to the side wall 2a so as to close the hole 6 formed in the side wall 2a of the oil pan 2. And the impact on the cost of the engine.

図４，図５は、本発明の第２，３の実施形態を示している。
図４に示す第２の実施形態、図５に示す第３の実施形態は、いずれも第１の実施形態とは異なる透視樹脂プレートを採用して、オイル油量点検窓を構成したものである。
すなわち、図４に示す第２の実施形態は、片側の一枚の透明樹脂プレート、ここでは外側の透明樹脂プレート７ａだけ、孔部６を塞ぐように側壁２ａに接着して、オイル油量点検窓５を構成したものである。 4 and 5 show the second and third embodiments of the present invention.
The second embodiment shown in FIG. 4 and the third embodiment shown in FIG. 5 each employ a fluororesin plate different from that of the first embodiment to constitute an oil oil amount inspection window. .
That is, in the second embodiment shown in FIG. 4, only one transparent resin plate on one side, in this case, only the outer transparent resin plate 7a, is adhered to the side wall 2a so as to close the hole 6, thereby checking the oil oil amount. The window 5 is configured.

図５に示す第３の実施形態は、第２の実施形態の変形例で、透明樹脂プレート７ａとして、一側部には孔部６に嵌挿可能な嵌挿部１３を有し、他側部はそのまま孔部６の周りの壁面に重なり合う重合部分１４としたままの構造を用い、嵌挿部１０を孔部６に嵌挿させ、他側部の重合部分１１を孔部６の縁部の壁面と重ねて、接着剤（図示しない）で側壁２に接着したものである。   The third embodiment shown in FIG. 5 is a modification of the second embodiment. As the transparent resin plate 7a, the third embodiment has an insertion portion 13 that can be inserted into the hole 6 on one side, and the other side. The part is used as it is with the overlapped portion 14 that overlaps the wall surface around the hole 6 as it is, the insertion portion 10 is inserted into the hole 6, and the overlapped portion 11 on the other side is the edge of the hole 6. And are adhered to the side wall 2 with an adhesive (not shown).

このような透明樹脂プレート７ａを用いてオイル油量点検窓５を構成しても、第１の実施形態と同様の効果を奏する。
図６および図７は、本発明の第４の実施形態を示す。
本実施形態は、エンジンの振動の影響を受けやすい板金製のオイルパン２に配慮して、例えば第１の実施形態のオイル油量点検窓５に工夫を施したものである。 Even if the oil quantity inspection window 5 is configured using such a transparent resin plate 7a, the same effects as those of the first embodiment can be obtained.
6 and 7 show a fourth embodiment of the present invention.
In the present embodiment, the oil oil amount inspection window 5 of the first embodiment is devised in consideration of the sheet metal oil pan 2 that is easily affected by engine vibration.

すなわち、オイルパン２は、エンジンの振動が伝わるが、板金製のオイルパン２だと薄肉なので、油量点検窓５が設置されている部位は共振する。そのため、側壁２ａに接着した透明樹脂プレート７ａ，７ｂは壁面から剥がれるおそれがあり、透明樹脂プレート７ａ，７ｂと側壁２ａとの間のシールが損なわれるおそれがある。
そこで、第４の実施形態は、図６および図７（図６中のＢ−Ｂ線に沿う断面）に示されるように孔部６や透明樹脂プレート７ａ，７ｂ（油量点検窓５）が配置されている側壁部分２ｃの部位だけ、オイルパン２の内側へ凹ませる工夫を施した（例えば角形）。 That is, the vibration of the engine is transmitted to the oil pan 2, but if the oil pan 2 made of sheet metal is thin, the portion where the oil amount inspection window 5 is installed resonates. Therefore, the transparent resin plates 7a and 7b adhered to the side wall 2a may be peeled off from the wall surface, and the seal between the transparent resin plates 7a and 7b and the side wall 2a may be impaired.
Therefore, in the fourth embodiment, as shown in FIG. 6 and FIG. 7 (cross section taken along line BB in FIG. 6), the hole 6 and the transparent resin plates 7a and 7b (oil amount inspection window 5) are provided. Only the portion of the arranged side wall portion 2c was devised so as to be recessed toward the inside of the oil pan 2 (for example, a square shape).

局所的に凹ました部分で形成される凹部１５は、オイル油量点検窓５が設置された板金部分の剛性強度を高める役割を果たすから、オイル油量点検窓５が設置された部位は、エンジンから伝わる振動で共振しにくくなる。これで、接着されている透明樹脂プレート７ａ，７ｂの剥がれは抑えられる。つまり、振動の影響がオイル油量点検窓５へ作用するのが抑えられ、透明樹脂プレート７ａ，７ｂと側壁２ａ間のシール性は良好に保ち続けられる。これにより、振動しやすい板金製のオイルパン２に適した油量点検窓５となり、油量点検窓５の信頼性が向上する。   Since the concave portion 15 formed by the locally recessed portion plays a role of increasing the rigidity and strength of the sheet metal portion where the oil oil amount inspection window 5 is installed, the portion where the oil oil amount inspection window 5 is installed is the engine. Resonance is less likely to occur due to vibrations transmitted from the Thus, peeling of the bonded transparent resin plates 7a and 7b is suppressed. That is, the influence of vibration on the oil oil amount inspection window 5 is suppressed, and the sealing performance between the transparent resin plates 7a and 7b and the side wall 2a is kept good. Thereby, it becomes the oil amount inspection window 5 suitable for the oil pan 2 made of sheet metal that easily vibrates, and the reliability of the oil amount inspection window 5 is improved.

側壁部分２ｃの剛性強度を高める措置は、凹部１５ではなく、図７中に二点鎖線で示すように側壁部分２ｃの孔部６や透明樹脂プレート７ａ，７ｂが配置された部位を、オイルパン２の外側へ突き出させた凸部１６でも同様である。
なお、凹部１５や凸部１６は、角形でなく、丸形でもよく、どのような形状でも構わない。 Measures for increasing the rigidity strength of the side wall portion 2c are not the recess 15 but the portion where the hole portion 6 and the transparent resin plates 7a and 7b of the side wall portion 2c are arranged as shown by a two-dot chain line in FIG. The same applies to the convex portion 16 projecting to the outside.
In addition, the recessed part 15 and the convex part 16 may not be a square but a round shape, and any shape may be sufficient as it.

図８は、本発明の第５の実施形態を示す。
本実施形態は、凹部１５や凸部１６の形成でも、振動の影響が十分に抑えられない場合の例を示す。
このときは、図８に示されるように凹部１５の周りのオイルパンの側壁２に、波形に成形した補強ビード２０を形成する。具体的には、凹部１５の上部側とフランジ１９により剛性強度が高くなっているオイルパン２の開口縁部間、凹部１５の下部側と剛性強度の高いオイルパン２の底壁間をそれぞれ結合するように補強ビード２０、ここでは例えば頂部がオイルパン２の外側へ突き出て上下方向に延びる直線状の補強ビード２０を形成する。むろん、側壁２に凸部１６（図７中の二点鎖線で図示）を形成した場合も同じである。 FIG. 8 shows a fifth embodiment of the present invention.
The present embodiment shows an example in which the influence of vibration cannot be sufficiently suppressed even when the concave portion 15 and the convex portion 16 are formed.
At this time, as shown in FIG. 8, a reinforcing bead 20 having a corrugated shape is formed on the side wall 2 of the oil pan around the recess 15. Specifically, the upper side of the recess 15 and the opening edge of the oil pan 2 having high rigidity by the flange 19, and the lower side of the recess 15 and the bottom wall of the oil pan 2 having high rigidity are connected to each other. Thus, the reinforcing bead 20, for example, a linear reinforcing bead 20 whose top portion protrudes to the outside of the oil pan 2 and extends in the vertical direction is formed. Of course, the same applies to the case where the convex portion 16 (illustrated by a two-dot chain line in FIG. 7) is formed on the side wall 2.

このように補強ビード２０を形成すると、一層、凹部１５（あるいは凸部１６）の剛性強度が高められ、油量点検窓５が配置される部位がオイルパン２に伝わる振動で振れにくくなる。つまり、油量点検窓５がオイルパン２に伝わる振動に影響されるのが抑えられる。これにより、一層、振動しやすいオイルパン２に適した油量点検窓５を得ることができる。   When the reinforcing bead 20 is formed in this way, the rigidity strength of the concave portion 15 (or the convex portion 16) is further increased, and the portion where the oil amount inspection window 5 is disposed is less likely to shake due to vibration transmitted to the oil pan 2. That is, it is possible to suppress the oil amount inspection window 5 from being affected by the vibration transmitted to the oil pan 2. Thereby, the oil amount inspection window 5 suitable for the oil pan 2 that is more likely to vibrate can be obtained.

なお、補強ビード２０は、図８中の二点鎖線に示されるように頂部がオイルパン２の内側へ突き出たビードでも構わない。
但し、図４〜図８において第１の実施形態と同じ部分には同一符号を付してその説明を省略した。
なお、本発明は上述した実施形態に限定されるものではなく、本発明の主旨を逸脱しない範囲内で種々可変して実施しても構わない。例えば上述した実施形態では、板金製のオイルパンに油量点検窓を設けた例を挙げたが、これに限らず、例えば合成樹脂製のオイルパンでも、アルミ合金製のオイルパンでもよい。また上述した実施形態では、透視プレート部材として、透明な合成樹脂部材で成形された透明樹脂プレートを用いたが、透視できる部材あれば、油量レベルの視認が行なえるので、無色の透明な合成樹脂部材に限定されるものではない。 Note that the reinforcement bead 20 may be a bead whose top portion protrudes to the inside of the oil pan 2 as indicated by a two-dot chain line in FIG.
However, in FIGS. 4-8, the same code | symbol was attached | subjected to the same part as 1st Embodiment, and the description was abbreviate | omitted.
Note that the present invention is not limited to the above-described embodiment, and various modifications may be made without departing from the spirit of the present invention. For example, in the embodiment described above, an example in which the oil amount inspection window is provided in the oil pan made of sheet metal has been described. However, the present invention is not limited to this. For example, an oil pan made of synthetic resin or an oil pan made of aluminum alloy may be used. In the embodiment described above, a transparent resin plate formed of a transparent synthetic resin member is used as the transparent plate member. However, if the member can be seen through, the oil amount level can be visually recognized, so a colorless transparent synthetic material is used. The resin member is not limited.
