Description

本発明は、車両などに配設される電子機器を覆うカバーに関する。   The present invention relates to a cover that covers an electronic device disposed in a vehicle or the like.

従来より、例えば車両のバッテリに直付けされるヒューズユニットが知られている（例えば、特許文献１参照）。   Conventionally, for example, a fuse unit that is directly attached to a battery of a vehicle is known (see, for example, Patent Document 1).

かかるヒューズユニットの一従来例が図４〜図６に示されている。このヒューズユニット５０は、バッテリ（図示せず）に固定されるヒューズユニット本体５１と、このヒューズユニット本体５１を覆うカバー６０とを備えている。カバー６０は、ヒューズユニット本体５１の側面を覆う第１カバー６１と、ヒューズユニット本体５１の上面を覆う第２カバー６２と、第１カバー６１と第２カバー６２間を連結する連結ヒンジ部６３とを備えている。連結ヒンジ部６３は、断面が長方形のベルト形状であり、撓み変形可能に形成されている。   One conventional example of such a fuse unit is shown in FIGS. The fuse unit 50 includes a fuse unit body 51 fixed to a battery (not shown) and a cover 60 that covers the fuse unit body 51. The cover 60 includes a first cover 61 that covers the side surface of the fuse unit main body 51, a second cover 62 that covers the upper surface of the fuse unit main body 51, and a connecting hinge portion 63 that connects the first cover 61 and the second cover 62. It has. The connecting hinge part 63 has a rectangular belt shape in cross section, and is formed to be able to bend and deform.

第２カバー６２は、連結ヒンジ部６３の撓み変形によって、ヒューズユニット本体５１の上面を覆う閉位置（図４の位置）と、ヒューズユニット本体５１の上面より離間する開位置（図５の位置）との間で変移する。   The second cover 62 has a closed position (the position in FIG. 4) that covers the upper surface of the fuse unit main body 51 and an open position (the position in FIG. 5) that is separated from the upper surface of the fuse unit main body 51 due to the bending deformation of the connecting hinge portion 63. Transition between.

この従来例では、第１カバー６１と第２カバー６２が連結ヒンジ部６３を介して連結されているので、第２カバー６２を閉位置と開位置との間で変移しても第２カバー６２が第１カバー６１より離脱しないため、メンテナンス時等の作業性が良い。   In this conventional example, since the first cover 61 and the second cover 62 are connected via the connecting hinge portion 63, the second cover 62 is moved even if the second cover 62 is changed between the closed position and the open position. However, since it does not detach | leave from the 1st cover 61, workability | operativity at the time of a maintenance etc. is good.

特開２０１３−７３８０８号公報JP 2013-73808 A

しかしながら、前記従来のカバー６０では、ベルト状の連結ヒンジ部６３が長手方向の全域に亘って断面均一に形成されている。従って、第２カバー６２が閉位置から開位置に変移すると、連結ヒンジ部６３が一直線状になる方向に引っ張られる。連結ヒンジ部６３は、この引っ張り力によって、図６に詳しく示すように、第１カバー６１と第２カバー６２からの各根本部６３ａで急に折れ曲がる形状（曲率半径が小さくなる形状）で撓み変形する。そのため、連結ヒンジ部６３の各根本部６３ａに応力が集中し、破損し易いという問題がある。   However, in the conventional cover 60, the belt-like connecting hinge portion 63 is formed to have a uniform cross section over the entire region in the longitudinal direction. Therefore, when the second cover 62 changes from the closed position to the open position, the connecting hinge 63 is pulled in a straight line. As shown in detail in FIG. 6, the connecting hinge portion 63 is bent and deformed in a shape that suddenly bends at each root portion 63 a from the first cover 61 and the second cover 62 (a shape in which the radius of curvature becomes small). To do. Therefore, there is a problem that stress concentrates on each root portion 63a of the connecting hinge portion 63 and is easily damaged.

そこで、本発明は、前記した課題を解決すべくなされたものであり、応力集中に起因する連結ヒンジ部の破損を防止できるカバーを提供することを目的とする。   Therefore, the present invention has been made to solve the above-described problems, and an object of the present invention is to provide a cover that can prevent breakage of a connecting hinge portion due to stress concentration.

本発明は、電子機器の第１面を覆う第１カバーと、前記電子機器の第２面を覆う第２カバーと、前記第１カバーと前記第２カバー間を連結し撓み変形可能な連結ヒンジ部とを備え、前記連結ヒンジ部の撓み変形によって、前記第２カバーが前記電子機器の第２面を覆う閉位置と第２面より離間する開位置との間で変移するカバーであって、前記第１カバーと前記第２カバーに連結される前記連結ヒンジ部の各根本部は、前記各根本部より中間箇所の肉厚よりも厚く形成され、各根本部の中間箇所側は、中間箇所に向かって厚みを徐々に薄く形成され、前記連結ヒンジ部は、ベルト状であり、前記各根本部は、帯状の内面側が中間箇所よりも突出して厚く形成され、各根本部の中間箇所側は、帯状の内面側が徐々に突出量を減らして厚みを徐々に薄く形成されたことを特徴とするカバーである。 The present invention provides a first cover that covers a first surface of an electronic device, a second cover that covers a second surface of the electronic device, and a connecting hinge that can be flexibly deformed by connecting the first cover and the second cover. A cover that is displaced between a closed position where the second cover covers the second surface of the electronic device and an open position where the second cover is spaced apart from the second surface by bending deformation of the connecting hinge portion, Each base part of the connecting hinge part connected to the first cover and the second cover is formed to be thicker than a thickness of an intermediate part from each base part, and an intermediate part side of each base part is an intermediate part The connecting hinge part is a belt-like shape, and each root part is formed so that the inner surface side of the belt protrudes thicker than the intermediate part, and the intermediate part side of each root part is The band-shaped inner surface gradually reduces the amount of protrusion and gradually increases the thickness. A cover which is characterized in that it is thin.

前記連結ヒンジ部の前記各根元部は、前記第１カバーと前記第２カバーの取付面に対して垂直方向よりも相手側のカバー側に傾斜して取り付けされたものであっても良い。前記電子機器は、バッテリに固定されるヒューズユニットであり、前記電子機器の前記第１面が前記ヒューズユニットの側面であり、前記電子機器の前記第２面が前記ヒューズユニットの上面であるものを含む。 Each of the root portions of the connecting hinge portion may be attached to be inclined with respect to the other cover side with respect to the attachment surfaces of the first cover and the second cover with respect to the vertical direction . Those prior Symbol electronic device is a fuse unit that is fixed to the battery, a side of the first surface is the fuse unit of the electronic device, the second surface of the electronic device is a top surface of the fuse unit including.

本発明によれば、第２カバーが閉位置から開位置に変移すると、連結ヒンジ部が一直線状になる方向に引っ張られるため、連結ヒンジ部の各根本部で折れ曲がる形状（曲率半径が小さくなる形状）で撓み変形する。ここで、各根本部は連結ヒンジ部の中間箇所の肉厚よりも厚く形成されているので、中間箇所に較べて曲げ剛性が高いため、各根本部で急な屈曲形状では曲がらない。そして、根本部の中間箇所側の肉厚が徐々に薄く形成されているので、この箇所の曲げ剛性が中間箇所に向かうに従って徐々に低くなっているため、この箇所で大きく（曲率半径が大きくなる形状で）曲がろうとする。従って、連結ヒンジ部の根本部での応力集中が軽減される。又、連結ヒンジ部の根本部は、中間箇所よりも肉厚が厚いために強度が高い。以上より、応力集中に起因する連結ヒンジ部の破損を防止できる。   According to the present invention, when the second cover is changed from the closed position to the open position, the connecting hinge part is pulled in a straight line direction, so that it is bent at each root part of the connecting hinge part (a shape with a small curvature radius). ) To bend and deform. Here, since each root part is formed thicker than the thickness of the intermediate part of the connecting hinge part, the bending rigidity is higher than that of the intermediate part, and therefore, the base part does not bend in a sharp bent shape. And since the thickness of the intermediate part side of the root part is formed gradually thin, the bending rigidity of this part gradually decreases toward the intermediate part, so it becomes large at this part (the radius of curvature becomes large). Try to bend (in shape). Therefore, the stress concentration at the base part of the connecting hinge part is reduced. Moreover, since the base part of a connection hinge part is thicker than an intermediate | middle part, its intensity | strength is high. From the above, it is possible to prevent the connection hinge portion from being damaged due to the stress concentration.

以下、本発明の一実施形態を図面に基づいて説明する。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

この実施形態では、本発明のカバーがヒューズユニットのカバーに適用されている。以下、説明する。   In this embodiment, the cover of the present invention is applied to the cover of the fuse unit. This will be described below.

図１及び図２（ａ）に示すように、ヒューズユニット１は、バッテリ（図示せず）にバッテリ端子３０を介して固定される電子機器であるヒューズユニット本体２と、このヒューズユニット本体２を覆うカバー１０とを備えている。ヒューズユニット本体２は、Ｌ字状に折れ曲がったバスバー３と、このバスバー３を絶縁性樹脂材でオーバーモールドして形成された保護樹脂部４とを備えている。バスバー３には、複数の端子部３ａと、過電流を阻止する可溶部（図示せず）とが設けられている。各端子部３ａは、保護樹脂部４より露出している。   As shown in FIGS. 1 and 2A, the fuse unit 1 includes a fuse unit main body 2 that is an electronic device fixed to a battery (not shown) via a battery terminal 30, and the fuse unit main body 2. And a cover 10 for covering. The fuse unit main body 2 includes a bus bar 3 bent into an L shape and a protective resin portion 4 formed by overmolding the bus bar 3 with an insulating resin material. The bus bar 3 is provided with a plurality of terminal portions 3a and a soluble portion (not shown) that prevents overcurrent. Each terminal portion 3 a is exposed from the protective resin portion 4.

カバー１０は、ヒューズユニット本体２の第１面である側面を覆う第１カバー１１と、ヒューズユニット本体２の第２面である上面を覆う第２カバー１２と、第１カバー１１と第２カバー１２間を連結する連結ヒンジ部１３とを備えている。第１カバー１１は、ヒューズユニット本体２にロック手段（図示せず）を介して固定されている。第１カバー１１には、左右一対のロック部１１ａが設けられている。第２カバー１２には、下記する閉位置でロック部１１ａに係止される左右一対のロックアーム１２ａが設けられている。   The cover 10 includes a first cover 11 that covers a side surface that is the first surface of the fuse unit body 2, a second cover 12 that covers an upper surface that is the second surface of the fuse unit body 2, and the first cover 11 and the second cover. And a connecting hinge portion 13 for connecting the twelve members. The first cover 11 is fixed to the fuse unit main body 2 via a lock means (not shown). The first cover 11 is provided with a pair of left and right lock portions 11a. The second cover 12 is provided with a pair of left and right lock arms 12a that are locked to the lock portion 11a at a closed position described below.

連結ヒンジ部１３は、断面が偏平長方形のベルト形状であり、撓み変形可能に形成されている。連結ヒンジ部１３は、図２（ｂ）、図３に詳しく示すように、第１カバー１１と第２カバー１２に連結される２つの根本部１３ａが中間箇所（根本部１３ａ以外の箇所）１３ｂの肉厚（ｔ１）よりも厚い肉厚（ｔ２）に形成されている。各根本部１３ａの中間箇所側は、中間箇所１３ｂに向かって厚みを徐々に薄く形成されている。各根本部１３ａは、帯状の内面側が中間箇所１３ｂよりも突出して厚く形成されている。各根本部１３ａの中間箇所側は、帯状の内面側が徐々に突出量を減らして厚みを徐々に薄く形成されている。又、各連結ヒンジ部１３は、図２（ｂ）、図３に詳しく示すように、第１カバー１１と第２カバー１２の取付面１１ｂ，１２ｂに対して垂直方向ではなく相手側のカバー側に傾斜して取り付けされている。傾斜角度Ａは、図２（ｂ）、図３に示すように、取付面１１ｂ，１２ｂに対して約４５度である。換言すれば、傾斜角度Ａは、閉位置における連結ヒンジ部１３の各根本部１３ａの延び方向（取付面１１ｂ，１２ｂに対して直角方向）と開位置における連結ヒンジ部１３の各根本部１３ａの引っ張られ方向（取付面１１ｂ，１２ｂに対して平行方向）との間に角度に設定されている。   The connecting hinge portion 13 has a flat rectangular belt shape in cross section and is formed to be able to bend and deform. As shown in detail in FIG. 2B and FIG. 3, the connecting hinge portion 13 has two root portions 13 a connected to the first cover 11 and the second cover 12 at intermediate positions (locations other than the root portion 13 a) 13 b. The wall thickness (t2) is larger than the wall thickness (t1). The intermediate portion side of each root portion 13a is formed so that the thickness is gradually reduced toward the intermediate portion 13b. Each root portion 13a is formed to be thicker with the band-shaped inner surface side protruding than the intermediate portion 13b. On the intermediate portion side of each root portion 13a, the band-shaped inner surface side is formed so that the thickness is gradually reduced by gradually reducing the amount of protrusion. Further, as shown in detail in FIGS. 2B and 3, each connecting hinge portion 13 is not perpendicular to the mounting surfaces 11 b and 12 b of the first cover 11 and the second cover 12, but on the opposite cover side. It is attached with an inclination. The inclination angle A is about 45 degrees with respect to the mounting surfaces 11b and 12b, as shown in FIGS. In other words, the inclination angle A is determined by the extending direction of each root portion 13a of the connecting hinge portion 13 in the closed position (perpendicular to the mounting surfaces 11b and 12b) and the root portion 13a of the connecting hinge portion 13 in the open position. It is set at an angle between the direction in which it is pulled (the direction parallel to the mounting surfaces 11b and 12b).

このような連結ヒンジ部１３で第１カバー１１に連結された第２カバー１２は、連結ヒンジ部１３の撓み変形によって、第２カバー１２がヒューズユニット本体２の上面を覆う閉位置（図１の位置）とヒューズユニット本体２の上面より離間する開位置（図２（ａ）の位置）との間で変移する。第２カバー１２の閉位置では、連結ヒンジ部１３が全域に亘って同じ曲率で屈曲して全体で大きな円弧形状に撓み変形する。閉位置に位置する第２カバー１２にあって、各ロックアーム１２ａをロック部１１ａよりロック解除し、第２カバー１２が閉位置から開位置に変移すると、連結ヒンジ部１３が一直線状になる方向に引っ張られる。連結ヒンジ部１３は、この引っ張り力によって、図３に示すように、第１カバー１１と第２カバー１２の各根本部１３ａで折れ曲がる形状（曲率半径が小さくなる形状）で撓み変形する。   The second cover 12 connected to the first cover 11 by the connecting hinge portion 13 is in a closed position (see FIG. 1) where the second cover 12 covers the upper surface of the fuse unit body 2 due to the deformation of the connecting hinge portion 13. Position) and an open position (position shown in FIG. 2A) that is separated from the upper surface of the fuse unit main body 2. In the closed position of the second cover 12, the connecting hinge portion 13 is bent with the same curvature over the entire region and is bent and deformed into a large arc shape as a whole. In the second cover 12 located at the closed position, when the lock arms 12a are unlocked from the lock portions 11a and the second cover 12 is changed from the closed position to the open position, the connecting hinge portion 13 becomes a straight line. Pulled on. As shown in FIG. 3, the connecting hinge portion 13 is bent and deformed in a shape that is bent at each root portion 13 a of the first cover 11 and the second cover 12 (a shape in which the radius of curvature becomes small).

ここで、各根本部１３ａは連結ヒンジ部１３の中間箇所１３ｂの肉厚ｔ１よりも厚い肉厚ｔ２に形成されているので、中間箇所１３ｂに較べて曲げ剛性が高いため、各根本部１３ａで急な屈曲形状では曲がらない。そして、各根本部１３ａの中間箇所側の肉厚が徐々に薄く形成されているので、この箇所の曲げ剛性が中間箇所１３ｂに向かうに従って徐々に低くなっているため、この箇所で大きく（曲率半径が大きくなる形状で）曲がろうとする。換言すれば、急な屈曲形状（曲率半径が小さな形状）で曲がらない。従って、連結ヒンジ部１３の根本部１３ａでの応力集中が軽減される。又、連結ヒンジ部１３の根本部１３ａは、中間箇所１３ｂよりも肉厚が厚いために強度が高い。以上より、応力集中に起因する連結ヒンジ部１３の破損を防止できる。   Here, since each root portion 13a is formed to have a thickness t2 that is thicker than the thickness t1 of the intermediate portion 13b of the connecting hinge portion 13, the bending rigidity is higher than that of the intermediate portion 13b. It does not bend in a steep bent shape. And since the thickness of the intermediate part side of each root part 13a is formed thinly gradually, since the bending rigidity of this part is gradually lowered toward the intermediate part 13b, it is large in this part (curvature radius). Try to bend). In other words, it does not bend with a steep bent shape (a shape with a small radius of curvature). Therefore, stress concentration at the root portion 13a of the connecting hinge portion 13 is reduced. Moreover, since the base part 13a of the connection hinge part 13 is thicker than the intermediate | middle part 13b, intensity | strength is high. From the above, it is possible to prevent the connecting hinge portion 13 from being damaged due to the stress concentration.

連結ヒンジ部１３は、ベルト状であり、その各根本部１３ａは、帯状の内面側が中間箇所１３ｂよりも突出して厚く形成されている。各根本部１３ａの中間箇所側は、帯状の内面側が徐々に突出量を減らして厚みを徐々に薄く形成されている。連結ヒンジ部１３の外面は、面一となるため、見た目が良い。   The connecting hinge portion 13 has a belt shape, and each of the root portions 13a is formed thicker such that the belt-like inner surface side protrudes from the intermediate portion 13b. On the intermediate portion side of each root portion 13a, the band-shaped inner surface side is formed so that the thickness is gradually reduced by gradually reducing the amount of protrusion. Since the outer surface of the connecting hinge portion 13 is flush, it looks good.

連結ヒンジ部１３の各根本部１３ａは、第１カバー１１と第２カバー１２の各取付面１１ｂ，１２ｂに対して相手側のカバー側に傾斜（傾斜角度：Ａ）して取り付けされている。従って、第２カバー１２が閉位置から開位置に変移し、連結ヒンジ部１３が一直線状になる方向に引っ張り力を受けるが、この引っ張り力による連結ヒンジ部１３の各根本部１３ａとこれに連続する中間箇所との間の折れ曲がり角度を小さくできる。これにより、最大曲げ応力を小さくできる。従来例では、図６に示すように、連結ヒンジ部６３の各根本部６３ａは、第１カバー６１と第２カバー６２の各取付面６１ｂ，６２ｂに対して垂直方向（取付角度：Ｂ＝約９０度）に取り付けされている。従って、第２カバー６２が閉位置から開位置に変移し、連結ヒンジ部６３が一直線状になる方向に引っ張り力を受けるが、この引っ張り力による連結ヒンジ部６３の各根本部６３ａとこれに連続する中間箇所の折れ曲がり角度が大きくなり、大きな最大曲げ応力が発生する。このように、この実施形態では、連結ヒンジ部１３の各根本部１３ａの取付角度によっても最大曲げ応力を小さくできる。   Each root portion 13a of the connecting hinge portion 13 is attached to the attachment surface 11b, 12b of the first cover 11 and the second cover 12 so as to be inclined (inclination angle: A) toward the other cover side. Accordingly, the second cover 12 is changed from the closed position to the open position, and the connecting hinge portion 13 receives a pulling force in a straight line direction, and the continuous hinge portion 13 of the connecting hinge portion 13 is continuously connected to the pulling force. The bending angle between the intermediate points can be reduced. Thereby, the maximum bending stress can be reduced. In the conventional example, as shown in FIG. 6, each root portion 63 a of the connecting hinge portion 63 is perpendicular to the mounting surfaces 61 b and 62 b of the first cover 61 and the second cover 62 (mounting angle: B = about 90 degrees). Therefore, the second cover 62 changes from the closed position to the open position, and the connecting hinge part 63 receives a pulling force in a straight line direction, and the continuous hinge part 63a of the connecting hinge part 63 by this pulling force continues to this. The bending angle of the intermediate portion is increased, and a large maximum bending stress is generated. Thus, in this embodiment, the maximum bending stress can be reduced also by the mounting angle of each root portion 13a of the connecting hinge portion 13.

この実施形態では、本発明がヒューズユニット１のカバー１０に適用された場合を示したが、ヒューズユニット１以外の電子機器を覆うカバー１０にも本発明は適用可能である。   In this embodiment, although the case where this invention was applied to the cover 10 of the fuse unit 1 was shown, this invention is applicable also to the cover 10 which covers electronic devices other than the fuse unit 1. FIG.

この実施形態では、連結ヒンジ部１３の中間箇所１３ｂが均一な断面形状であるが、根本部１３ａよりも曲げ剛性が低ければ不均一な断面形状であっても良い。   In this embodiment, the intermediate portion 13b of the connecting hinge portion 13 has a uniform cross-sectional shape, but may have a non-uniform cross-sectional shape as long as the bending rigidity is lower than that of the root portion 13a.

この実施形態では、連結ヒンジ部１３は、断面形状が偏平長方形であるが、偏平楕円形状であっても良く、ベルト状であれば断面形状を問わない。   In this embodiment, the connecting hinge portion 13 has a flat rectangular cross section, but may have a flat elliptical shape.
