Description

本発明は、例えば電気自動車等に搭載されるバッテリを収容するバッテリ容器に関するものである。   The present invention relates to a battery container that houses a battery mounted on, for example, an electric vehicle.

従来より、例えば電気自動車は走行用モーター等に電力を供給するための多くのバッテリを備えている。特許文献１に開示されているように、バッテリは、バッテリ容器に収容された状態で車体のフロア下に搭載されるのが一般的である。バッテリ容器は、下側に位置するトレイ部材と、上側に位置するカバー部材とで構成されている。バッテリは、トレイ部材に載置された状態でカバー部材によって覆われている。トレイ部材は、底壁部と側壁部とからなり、側壁部に複数の金属プレートがインサート成形された樹脂成形品である。   Conventionally, for example, an electric vehicle is provided with a number of batteries for supplying electric power to a traveling motor or the like. As disclosed in Patent Document 1, the battery is generally mounted under the floor of the vehicle body while being accommodated in a battery container. The battery container is composed of a tray member located on the lower side and a cover member located on the upper side. The battery is covered with a cover member in a state of being placed on the tray member. The tray member is a resin molded product including a bottom wall portion and a side wall portion, and a plurality of metal plates are insert-molded on the side wall portion.

特許第５０２９２６３号公報Japanese Patent No. 5029263

特に車両の走行時には、上方向の加速度が作用することもあり、バッテリ容器には大きな荷重が加わる。   In particular, when the vehicle is traveling, acceleration in the upward direction may act, and a large load is applied to the battery container.

ところが、特許文献１では、側壁部に埋め込まれている複数の金属プレートが互いに間隔をあけて配置されている。従って、金属プレートと金属プレートとの間は樹脂材だけになり、十分な補強効果が得られない恐れがある。   However, in Patent Document 1, a plurality of metal plates embedded in the side wall portions are arranged at intervals. Therefore, there is only a resin material between the metal plate and there is a possibility that a sufficient reinforcing effect cannot be obtained.

そこで、金属プレート同士を結合することが考えられるが、各金属プレートには製造誤差が生じていて金属プレート同士を結合することが困難になる恐れがある。   Thus, it is conceivable to join the metal plates together, but there is a possibility that it is difficult to join the metal plates due to a manufacturing error in each metal plate.

本発明は、かかる点に鑑みてなされたものであり、その目的とするところは、バッテリ容器に複数の補強材を設ける場合に、補強材に製造誤差が生じていても結合できるようにして高い補強効果が得られるようにすることにある。   The present invention has been made in view of the above points, and the object of the present invention is to provide a battery container with a plurality of reinforcing members so that the reinforcing members can be combined even if there are manufacturing errors. The purpose is to obtain a reinforcing effect.

上記目的を達成するために、本発明では、製造誤差を許容可能なジョイント部材によって複数の補強材を結合した状態でインサート成形するようにした。   In order to achieve the above object, in the present invention, insert molding is performed in a state in which a plurality of reinforcing members are coupled by a joint member that can allow manufacturing errors.

第１の発明は、
バッテリを収容するバッテリ容器において、
複数の補強材と、
上記補強材を結合するジョイント部材と、
上記補強材と上記ジョイント部材とがインサート成形された樹脂材とを備え、
上記ジョイント部材には、上記補強材に結合する結合部が設けられ、
上記結合部と上記補強材との間には、上記補強材の製造誤差を許容するための空隙部が設けられていることを特徴とする。 The first invention is
In a battery container that houses a battery,
Multiple reinforcements,
A joint member for coupling the reinforcing material;
The reinforcing material and the joint member are provided with a resin material in which insert molding is performed,
The joint member is provided with a coupling portion coupled to the reinforcing material,
A gap for allowing a manufacturing error of the reinforcing material is provided between the coupling portion and the reinforcing material.

この構成によれば、複数の補強材をジョイント部材で結合することで補強材が連続した状態でインサート成形されるので、バッテリ容器の補強効果が十分に得られる。そして、補強材をジョイント部材で結合する際に、補強材に製造誤差が生じている場合、ジョイント部材の結合部と補強材との間の空隙部が縮小したり、拡大することで製造誤差が許容されるので、製造誤差が生じていても補強材を結合することが可能になる。   According to this configuration, since the plurality of reinforcing members are joined by the joint member and insert molding is performed in a state where the reinforcing members are continuous, the effect of reinforcing the battery container can be sufficiently obtained. And, when manufacturing error occurs in the reinforcing material when the reinforcing material is connected with the joint member, the manufacturing error is reduced by reducing or expanding the gap between the connecting portion of the joint member and the reinforcing material. Since it is allowed, the reinforcing material can be combined even if a manufacturing error occurs.

第２の発明は、第１の発明において、
複数の上記補強材は、複数の上記ジョイント部材により環状をなすように結合されていることを特徴とする。 According to a second invention, in the first invention,
The plurality of reinforcing members are connected to form a ring by the plurality of joint members.

この構成によれば、補強材を環状にすることで補強効果がより一層高まる。そして、各補強材の製造誤差を許容することで補強材を容易に環状にすることが可能になる。   According to this configuration, the reinforcing effect is further enhanced by making the reinforcing material annular. And it becomes possible to make a reinforcing material into an annular | circular shape easily by accepting the manufacturing error of each reinforcing material.

第３の発明は、第２の発明において、
上記補強材は金属製であり、
上記ジョイント部材は樹脂製であることを特徴とする。 According to a third invention, in the second invention,
The reinforcing material is made of metal,
The joint member is made of resin.

この構成によれば、補強材を金属製とすることで補強効果がより一層高まる。一方、ジョイント部材を樹脂材とすることで、空隙部を設けることのできる形状が容易に、かつ、確実に得られる。   According to this configuration, the reinforcing effect is further enhanced by making the reinforcing material metal. On the other hand, when the joint member is made of a resin material, a shape capable of providing a gap is easily and reliably obtained.

第１の発明によれば、補強材に結合する結合部をジョイント部材に設け、結合部と補強材との間に補強材の製造誤差を許容するための空隙部を設けたので、製造誤差が生じている補強材を複数結合でき、高い補強効果を得ることができる。   According to the first aspect of the invention, since the coupling portion coupled to the reinforcing material is provided in the joint member, and the gap portion for allowing the manufacturing error of the reinforcing material is provided between the coupling portion and the reinforcing material, the manufacturing error is reduced. A plurality of generated reinforcing materials can be combined, and a high reinforcing effect can be obtained.

第２の発明によれば、補強材を複数のジョイント部材により環状をなすように結合したので、より高い補強効果を容易に得ることができる。   According to the second aspect of the invention, since the reinforcing material is joined by the plurality of joint members so as to form an annular shape, a higher reinforcing effect can be easily obtained.

第３の発明によれば、補強材を金属製として高い補強効果を得ることができ、この場合にジョイント部材を樹脂製として容易に、かつ、確実に空隙部を設けることのできる形状を得ることができる。   According to the third aspect of the invention, the reinforcing material can be made of metal to obtain a high reinforcing effect, and in this case, the joint member can be made of resin, and a shape capable of easily and reliably providing the gap can be obtained. Can do.

以下、本発明の実施形態を図面に基づいて詳細に説明する。尚、以下の好ましい実施形態の説明は、本質的に例示に過ぎず、本発明、その適用物或いはその用途を制限することを意図するものではない。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the following description of the preferred embodiment is merely illustrative in nature, and is not intended to limit the present invention, its application, or its use.

図１は、本発明の実施形態に係るバッテリ容器１００の斜視図である。このバッテリ容器１００は、例えば、電気自動車やハイブリッド自動車（プラグインハイブリット自動車を含む）等に搭載されている走行用バッテリ（図示せず）を収容するためのものである。走行用バッテリとは、自動車の走行用モーター等に電力を供給するためのバッテリであり、上記自動車には一般に複数個搭載されている。   FIG. 1 is a perspective view of a battery container 100 according to an embodiment of the present invention. The battery container 100 is for housing a battery for traveling (not shown) mounted on, for example, an electric vehicle, a hybrid vehicle (including a plug-in hybrid vehicle), or the like. A traveling battery is a battery for supplying electric power to a traveling motor or the like of an automobile, and a plurality of such batteries are generally mounted on the automobile.

バッテリ容器１００は、バッテリを下方から支持するためのバッテリ支持部材１と、走行用バッテリを上方から覆うように形成されたカバー部材１０１とを備えている。バッテリ支持部材１によって走行用バッテリの下方が覆われ、カバー部材１０１によって走行用バッテリの側方及び上方が覆われる。バッテリ支持部材１とカバー部材１０１との間は、シールされており、水の浸入が抑制されるようになっている。バッテリ容器１００は、例えば自動車のフロアパネルの下方に収容することができる。   The battery container 100 includes a battery support member 1 for supporting the battery from below, and a cover member 101 formed so as to cover the battery for traveling from above. The battery supporting member 1 covers the lower side of the traveling battery, and the cover member 101 covers the side and upper side of the traveling battery. The space between the battery support member 1 and the cover member 101 is sealed so that the ingress of water is suppressed. The battery container 100 can be accommodated, for example, below the floor panel of an automobile.

この実施形態では、バッテリ容器１００の形状が車体の前後方向または左右方向に長く延びる形状となっている。そして、バッテリ容器１００の長手方向一側（図１の右側）は、他側（図１の左側）に比べて幅広に形成されている。これは、バッテリ容器１００を収容する車両側のスペースの形状に対応させたことによるものである。   In this embodiment, the shape of the battery container 100 is a shape that extends long in the front-rear direction or the left-right direction of the vehicle body. And the longitudinal direction one side (right side of FIG. 1) of the battery container 100 is formed wider than the other side (left side of FIG. 1). This is because it corresponds to the shape of the space on the vehicle side in which the battery container 100 is accommodated.

バッテリ支持部材１は、バッテリを下方から支持する支持部（底壁部）２と、支持部２を車体のフレーム等に固定するための複数のステー３とを備えている。支持部２は、バッテリ容器１００の形状に対応するように、長手方向一側が他側に比べて幅広に形成されたトレイ状をなしている。支持部２の周縁部には、上方へ突出して環状に延びる環状突出部２ａが形成されており、この環状突出部２ａの内側に走行用バッテリが搭載される。また、支持部２の上面における環状突出部２ａの内側には、支持部２の幅方向に延びる複数の突条部２ｂが支持部２の長手方向に間隔をあけて設けられている。突条部２ｂの長手方向両端部は、環状突出部２ａに連続している。また、支持部２における突条部２ｂの間の部分は、波型に形成されている。   The battery support member 1 includes a support part (bottom wall part) 2 that supports the battery from below, and a plurality of stays 3 for fixing the support part 2 to a frame or the like of the vehicle body.

図９〜図１１に示すように、第１上側補強材２１は、角筒状をなしており、その内部には、補強用の壁部２１ａが形成されている。壁部２１ａは、略水平に延び、第１上側補強材２１の上下方向中間部に位置している。第１上側補強材２１は、支持部２の長手方向一側の縁部に沿って支持部２の幅方向に直線状に延びている。図４に示すように、第１上側補強材２１は、第１下側補強材１１の上面部に重なるように配置される。第１上側補強材２１の長手方向の寸法は、樹脂材４０の長手方向一側の寸法よりも短く設定されている。第１上側補強材２１の両側面部と、上面部とは樹脂材４０によって被覆されている。   As shown in FIGS. 9-11, the 1st upper side reinforcement material 21 has comprised the rectangular tube shape, and the wall part 21a for reinforcement is formed in the inside. The wall portion 21 a extends substantially horizontally and is positioned at the middle portion in the vertical direction of the first upper reinforcing member 21. The first upper reinforcing member 21 extends linearly in the width direction of the support portion 2 along the edge on one side in the longitudinal direction of the support portion 2. As shown in FIG. 4, the first upper reinforcing member 21 is disposed so as to overlap the upper surface portion of the first lower reinforcing member 11. The dimension in the longitudinal direction of the first upper reinforcing member 21 is set to be shorter than the dimension on one side in the longitudinal direction of the resin material 40. Both side surface portions and the upper surface portion of the first upper reinforcing member 21 are covered with the resin material 40.

第２上側補強材２２も角筒状をなしており、内部には第１上側補強材２１と同様な壁部２２ａが形成されている。第２上側補強材２２は、支持部２の幅方向の一縁部に沿うように形成されており、第１〜第７下側補強材１１〜１７の上面に重なるように配置される。第２上側補強材２２の長手方向他端部は、第７下側補強材１７よりも支持部２の長手方向他側に突出している。   The second upper reinforcing member 22 also has a rectangular tube shape, and a wall portion 22a similar to the first upper reinforcing member 21 is formed inside. The second upper reinforcing material 22 is formed along one edge of the support portion 2 in the width direction, and is disposed so as to overlap the upper surfaces of the first to seventh lower reinforcing materials 11 to 17. The other end portion in the longitudinal direction of the second upper reinforcing member 22 protrudes to the other side in the longitudinal direction of the support portion 2 from the seventh lower reinforcing member 17.

また、支持部２は長手方向一側が他側に比べて幅広であるため、この支持部２の一縁部の形状に対応するように第２上側補強材２２が屈曲しており、第２上側補強材２２の長手方向中間部には、２つの屈曲部２２ｂ、２２ｂが形成されることになる。第２上側補強材２２の長手方向両側は支持部２の長手方向に沿って直線状に延びている。   Further, since the support portion 2 is wider on one side in the longitudinal direction than the other side, the second upper reinforcing material 22 is bent so as to correspond to the shape of one edge portion of the support portion 2, and the second upper side Two bent portions 22b and 22b are formed in the middle portion of the reinforcing member 22 in the longitudinal direction. Both longitudinal sides of the second upper reinforcing member 22 extend linearly along the longitudinal direction of the support portion 2.

第２上側補強材２２は、第４上側補強材１４〜第７上側補強材１７の切欠部１４ｃ、１５ｃ、１６ｃ、１７ｃに押し込まれた状態で嵌合するようになっている。また、第２上側補強材２２における第３下側補強材１３に重なる部分は、突条部１３ｂの長手方向の端部に対して外側から当接するようになっている。   The second upper reinforcing member 22 is fitted in a state where it is pushed into the notches 14c, 15c, 16c, and 17c of the fourth upper reinforcing member 14 to the seventh upper reinforcing member 17.

第２上側補強材２２の屈曲部２２ｂ、２２ｂは押し出し成形後に形成する。従って、屈曲部２２ｂ、２２ｂの形成後に外力を除くとスプリングバック現象によって第２上側補強材２２が元の直線形状に近づく方向に僅かに変形することがある。このことに対し、この実施形態では、第２上側補強材２２を切欠部１４ｃ、１５ｃ、１６ｃ、１７ｃに嵌合させ、かつ、突条部１３ｂに当接させて設計通りの形状となるように形状を維持しているので、第２上側補強材２２のスプリングバック現象による変形を未然に防止することが可能になる。尚、第１〜第７下側補強材１１〜１７は、後述する成形型に設けられている位置決め部によって成形型内で位置決めされるようになっている。位置決め部とは、例えば位置決めピンや位置決め孔である。成形型に位置決めピンを設ける場合には、第１〜第７下側補強材１１〜１７に位置決めピンが嵌入する孔部を設ければよく、また、成形型に位置決め孔を設ける場合には、第１〜第７下側補強材１１〜１７に位置決め孔に嵌入するピンを設ければよい。第１〜第７下側補強材１１〜１７の位置決め構造は上述した構造に限られるものではない。   The bent portions 22b and 22b of the second upper reinforcing member 22 are formed after extrusion molding. Therefore, if the external force is removed after the bent portions 22b and 22b are formed, the second upper reinforcing member 22 may be slightly deformed in a direction approaching the original linear shape due to the spring back phenomenon. On the other hand, in this embodiment, the second upper reinforcing member 22 is fitted into the notches 14c, 15c, 16c, and 17c and is brought into contact with the protrusion 13b so as to have a shape as designed. Since the shape is maintained, it is possible to prevent the second upper reinforcing member 22 from being deformed due to the springback phenomenon. In addition, the 1st-7th lower reinforcement material 11-17 is positioned within a shaping | molding die by the positioning part provided in the shaping | molding die mentioned later. The positioning part is, for example, a positioning pin or a positioning hole. When providing a positioning pin in the mold, it is only necessary to provide a hole in which the positioning pin is fitted in the first to seventh lower reinforcing members 11 to 17, and when providing a positioning hole in the mold, What is necessary is just to provide the pin inserted in a positioning hole in the 1st-7th lower reinforcement material 11-17. The positioning structure of the first to seventh lower reinforcement members 11 to 17 is not limited to the above-described structure.

第３上側補強材２３も角筒状をなしており、内部には第１上側補強材２１と同様な壁部２３ａが形成されている。第３上側補強材２３は、支持部２の幅方向の他縁部に沿うように形成されており、第７下側補強材１７よりも支持部２の長手方向他側に配置される。   The third upper reinforcing member 23 also has a rectangular tube shape, and a wall portion 23a similar to the first upper reinforcing member 21 is formed inside. The third upper reinforcement member 23 is formed along the other edge portion in the width direction of the support portion 2, and is disposed on the other side in the longitudinal direction of the support portion 2 with respect to the seventh lower reinforcement member 17.

第３上側補強材２３は、支持部２の長手方向他側の縁部の形状に対応するように屈曲しており、第３上側補強材２３の長手方向中間部に２つの屈曲部２３ｂ、２３ｂが形成されている。この屈曲部２３ｂ、２３ｂも押し出し成形後に形成される。   The third upper reinforcing member 23 is bent so as to correspond to the shape of the edge on the other side in the longitudinal direction of the support portion 2, and two bent portions 23 b and 23 b are provided at the middle portion in the longitudinal direction of the third upper reinforcing member 23. Is formed. The bent portions 23b and 23b are also formed after extrusion molding.

第４上側補強材２４は、第２上側補強材２２と同じものであり、壁部２４ａと屈曲部２４ｂ、２４ｂとを有している。第４上側補強材２４と第２上側補強材２２とは、支持部２の幅方向中心を通って長手方向に延びる中心線を対称の中心として線対称となるように配置される。第４上側補強材２４も切欠部１４ｃ、１５ｃ、１６ｃ、１７ｃに嵌合し、かつ、突条部１３ｂの端部に外側から当接しており、第４上側補強材２４のスプリングバック現象による変形が未然に防止されている。   The fourth upper reinforcing member 24 is the same as the second upper reinforcing member 22, and has a wall portion 24a and bent portions 24b and 24b. The fourth upper reinforcement member 24 and the second upper reinforcement member 22 are arranged so as to be line symmetric with respect to a center line extending in the longitudinal direction through the center in the width direction of the support portion 2. The fourth upper reinforcing member 24 is also fitted in the notches 14c, 15c, 16c, and 17c, and is in contact with the end of the ridge 13b from the outside, and the fourth upper reinforcing member 24 is deformed by a springback phenomenon. Has been prevented.

つまり、支持部２の平面視で、第２上側補強材２２及び第４上側補強材２４と、第１〜第７下側補強材１１〜１７とは互いに交差している。   That is, the second upper reinforcing material 22 and the fourth upper reinforcing material 24 and the first to seventh lower reinforcing materials 11 to 17 intersect each other in a plan view of the support portion 2.

図１２及び図１３に示すように、第１〜第４ジョイント部材３１〜３４は、樹脂材料を成形してなる樹脂製部材である。第１〜第４ジョイント部材３１〜３４を構成する樹脂材料としては、樹脂材４０と同系のものが好ましい。   As shown in FIGS. 12 and 13, the first to fourth joint members 31 to 34 are resin members formed by molding a resin material. The resin material constituting the first to fourth joint members 31 to 34 is preferably the same as that of the resin material 40.

図４に示すように、第１ジョイント部材３１は、支持部２の長手方向一側のコーナー部の形状に沿うように湾曲形成されている。図９及び図１２に示すように、第１ジョイント部材３１の一端部には、一対の差し込み部（結合部）３１ａ、３１ａが突設され、また、他端部には、一対の差し込み部（結合部）３１ｂ、３１ｂが突設されている。一方の差し込み部３１ａ、３１ａは、上下方向に間隔をあけて配置されており、第１上側補強材２１の端部に差し込まれた状態で該第１上側補強材２１に結合する。他方の差し込み部３１ｂ、３１ｂは、第２上側補強材２２の端部に差し込まれた状態で該第２上側補強材２２に結合する。   As shown in FIG. 4, the first joint member 31 is curved so as to follow the shape of the corner portion on one side in the longitudinal direction of the support portion 2. As shown in FIGS. 9 and 12, a pair of insertion portions (coupling portions) 31 a and 31 a protrude from one end of the first joint member 31, and a pair of insertion portions ( (Coupling part) 31b and 31b are projected. One insertion part 31a, 31a is arrange | positioned at intervals at the up-down direction, and couple | bonds with this 1st upper side reinforcement material 21 in the state inserted in the edge part of the 1st upper side reinforcement material 21. As shown in FIG. The other insertion portions 31 b and 31 b are coupled to the second upper reinforcing member 22 while being inserted into the end portions of the second upper reinforcing member 22.

第１ジョイント部材３１の一方の差し込み部３１ａ、３１ａが第１上側補強材２１の端部に差し込まれ、かつ、他方の差し込み部３１ｂ、３１ｂが第２上側補強材２２の端部に差し込まれた状態では、差し込み部３１ａ、３１ａの外周面と第１上側補強材２１の内周面との間、及び差し込み部３１ｂ、３１ｂの外周面と第２上側補強材２２の内周面との間に若干の隙間からなる空隙部Ｓ（図１４に示す）が形成される。これにより、差し込み部３１ａ、３１ａと第１上側補強材２１とが緩く嵌合し、また、差し込み部３１ｂ、３１ｂと第２上側補強材２２とが緩く嵌合する。   One insertion part 31 a, 31 a of the first joint member 31 is inserted into the end part of the first upper reinforcement member 21, and the other insertion part 31 b, 31 b is inserted into the end part of the second upper reinforcement member 22. In the state, between the outer peripheral surface of the insertion portions 31 a and 31 a and the inner peripheral surface of the first upper reinforcing member 21, and between the outer peripheral surface of the insertion portions 31 b and 31 b and the inner peripheral surface of the second upper reinforcing member 22. A gap S (shown in FIG. 14) consisting of a slight gap is formed. Thereby, the insertion parts 31a and 31a and the 1st upper side reinforcement material 21 fit loosely, and the insertion parts 31b and 31b and the 2nd upper side reinforcement material 22 fit loosely.

空隙部Ｓは、第１上側補強材２１や第２上側補強材２２に生じた製造誤差や組み付け誤差を許容するためのものである。例えば、第１上側補強材２１の第１ジョイント部材３１側の端部と、第２上側補強材２２の第２ジョイント部材３２側の端部とが上下方向にずれていても、そのずれを第１ジョイント部材３１との嵌合部分の空隙部Ｓで吸収して許容できる。よって、製造誤差の度合いによっては空隙部Ｓが狭くて差し込み部３１ａ、３１ｂの全周には形成されずに一部にのみ形成される場合があったり、図１４に示す状態よりも広い場合もある。   The gap S is for allowing a manufacturing error or an assembly error that has occurred in the first upper reinforcing member 21 or the second upper reinforcing member 22. For example, even if the end on the first joint member 31 side of the first upper reinforcing member 21 and the end on the second joint member 32 side of the second upper reinforcing member 22 are shifted in the vertical direction, the shift is reduced. It can be absorbed and absorbed in the gap S of the fitting portion with the one joint member 31. Therefore, depending on the degree of manufacturing error, the gap S may be narrow and may not be formed on the entire circumference of the insertion portions 31a and 31b, but may be formed only partially, or may be wider than the state shown in FIG. is there.

As shown in FIGS. 9 and 13, a pair of insertion portions (coupling portions) 33a and 33a project from one end portion of the third joint member 33, and a pair of insertion portions (coupling portions) are connected to the other end portion. Part) 33b, 33b is projected. One insertion part 33a, 33a is arrange | positioned at intervals at the up-down direction, and couple | bonds with this 3rd upper reinforcement 23 in the state inserted in the edge part of the 3rd upper reinforcement 23. The other insertion portions 33 b and 33 b are coupled to the second upper reinforcing member 22 in a state of being inserted into the end portion of the second upper reinforcing member 22. A gap (not shown) as described above is formed between the third joint member 33 and the second upper reinforcing member 22 and the third upper reinforcing member 23 so that manufacturing errors can be allowed.

その後、成形型を閉じて溶融状態の樹脂材料をキャビティに射出する。射出された樹脂材料は、第１〜第７下側補強材１１〜１７、第１〜第４上側補強材２１〜２４及び第１〜第４ジョイント部材３１〜３４を被覆するように流動して固化する。これにより、第１〜第７下側補強材１１〜１７、第１〜第４上側補強材２１〜２４及び第１〜第４ジョイント部材３１〜３４がインサート成形されたバッテリ支持部材１が得られる。尚、ステー３は、脱型後に締結すればよい。   Thereafter, the mold is closed and the molten resin material is injected into the cavity. The injected resin material flows so as to cover the first to seventh lower reinforcing members 11 to 17, the first to fourth upper reinforcing members 21 to 24, and the first to fourth joint members 31 to 34. Solidify. Thereby, the battery support member 1 in which the first to seventh lower reinforcement members 11 to 17, the first to fourth upper reinforcement members 21 to 24, and the first to fourth joint members 31 to 34 are insert-molded is obtained. . The stay 3 may be fastened after demolding.

バッテリ支持部材１の支持部２はバッテリを下方から支持する部分であるが、このバッテリの荷重を直接受ける支持部２に第１〜第７下側補強材１１〜１７が配置されることになるので、バッテリの荷重が第１〜第７下側補強材１１〜１７に確実に作用するようになり、第１〜第７下側補強材１１〜１７による補強効果が十分に得られる。また、第１〜第７下側補強材１１〜１７がインサート成形されていることにより、第１〜第７下側補強材１１〜１７とその周囲の樹脂材４０とが強固に一体化して補強効果がより一層高まる。よって、樹脂材４０の肉厚を薄くすることが可能になる。   The support portion 2 of the battery support member 1 is a portion that supports the battery from below, and the first to seventh lower reinforcement members 11 to 17 are disposed on the support portion 2 that directly receives the load of the battery. Therefore, the load of the battery acts on the first to seventh lower reinforcement members 11 to 17 surely, and the reinforcing effect by the first to seventh lower reinforcement members 11 to 17 is sufficiently obtained. Further, since the first to seventh lower reinforcing members 11 to 17 are insert-molded, the first to seventh lower reinforcing members 11 to 17 and the surrounding resin material 40 are firmly integrated and reinforced. The effect is further enhanced. Therefore, the thickness of the resin material 40 can be reduced.

また、この実施形態では、第１〜第７下側補強材１１〜１７及び第１〜第４上側補強材２１〜２４が縦横に延びるように設けられているので、上下方向の荷重だけでなく、例えば車両衝突時のように側方からの衝撃にも十分に耐え得ることができる。さらに、第１〜第４上側補強材２１〜２４と第１〜第４ジョイント部材３１〜３４とが環状に連続しているので、このことによっても側方からの衝撃に強い構造とすることができる。   Moreover, in this embodiment, since the 1st-7th lower side reinforcement materials 11-17 and the 1st-4th upper side reinforcement materials 21-24 are provided so that it may extend in length and breadth, not only the load of an up-down direction For example, it can sufficiently withstand a side impact such as a vehicle collision. Furthermore, since the 1st-4th upper side reinforcement materials 21-24 and the 1st-4th joint members 31-34 are continuing cyclically | annularly, it can also be set as a structure strong against the impact from a side by this. it can.

以上説明したように、この実施形態によれば、第１及び第２上側補強材２１、２２に結合する第１ジョイント部材３１の差し込み部３１ａ、３１ｂを設け、差し込み部３１ａ、３１ｂの外周面と第１及び第２上側補強材２１、２２との間に第１及び第２上側補強材２１、２２の製造誤差を許容するための空隙部Ｓを設けたので、製造誤差が生じている補強材２１、２２を複数結合した状態でインサート成形することができ、高い補強効果を得ることができる。   As described above, according to this embodiment, the insertion portions 31a and 31b of the first joint member 31 coupled to the first and second upper reinforcing members 21 and 22 are provided, and the outer peripheral surfaces of the insertion portions 31a and 31b are provided. Since the gap portion S for allowing the manufacturing error of the first and second upper reinforcing members 21 and 22 is provided between the first and second upper reinforcing members 21 and 22, the reinforcing member in which the manufacturing error occurs. Insert molding can be performed in a state where a plurality of 21 and 22 are coupled, and a high reinforcing effect can be obtained.

また、第２、第４上側補強材２２、２４を押し出し成形材としてバッテリ容器１の形状や構造に対応するように屈曲加工した場合に、第２、第４上側補強材２２、２４を第４〜第７下側補強材１４〜１７の切欠部１４ｃ〜１７ｃに嵌合させることで第２、第４上側補強材２２、２４の形状を第４〜第７下側補強材１４〜１７で維持することが可能になる。よって、第２、第４上側補強材２２、２４のスプリングバック現象が未然に防止される。   Further, when the second and fourth upper reinforcing members 22 and 24 are bent as extrusion molding materials so as to correspond to the shape and structure of the battery container 1, the second and fourth upper reinforcing members 22 and 24 are changed to the fourth. The shapes of the second and fourth upper reinforcing members 22 and 24 are maintained by the fourth to seventh lower reinforcing members 14 to 17 by being fitted to the notches 14c to 17c of the seventh lower reinforcing members 14 to 17. It becomes possible to do. Therefore, the springback phenomenon of the second and fourth upper reinforcing members 22 and 24 is prevented in advance.

また、第１〜第７下側補強材１１〜１７及び第１〜第４上側補強材２１〜２４を組み合わせて支持部２を補強するようにしたので、支持部２における走行用バッテリの荷重分布に対応するように補強でき、バッテリ容器１００を軽量、かつ、高剛性にすることができる。   Moreover, since the support part 2 was reinforced by combining the 1st-7th lower side reinforcement materials 11-17 and the 1st-4th upper side reinforcement materials 21-24, the load distribution of the battery for driving | running | working in the support part 2 The battery container 100 can be made lightweight and highly rigid.

また、第１〜第７下側補強材１１〜１７及び第２、第４上側補強材２２、２４を平面視で互いに交差させ、かつ、上下に重なるように配置している。これにより、補強効果をより一層高めることができる。   Further, the first to seventh lower reinforcing members 11 to 17 and the second and fourth upper reinforcing members 22 and 24 are arranged so as to intersect with each other and overlap each other in a plan view. Thereby, the reinforcing effect can be further enhanced.

また、図１５及び図１６に示す変形例のように、第４上側補強材２４を長手方向に２分割可能な構造にしてもよい。この場合、第４上側補強材２４が、第１補強材２４Ａと第２補強材２４Ｂとからなり、これら補強材２４Ａ、２４Ｂをジョイント部材３５（図１６に示す）で結合する。第１補強材２４Ａは１つの屈曲部２４ｂを有し、また、第２補強材２４Ｂも１つの屈曲部２４ｂを有している。このように、各補強材２４Ａ、２４Ｂが１つの屈曲部２４ｂしか有していないので、２つ以上の屈曲部を形成する場合に比べて各補強材２４Ａ、２４Ｂのスプリングバックが少なくなり、その結果、第４上側補強材２４の寸法精度が向上することになる。   Moreover, you may make it the structure which can divide | segment the 4th upper side reinforcement material 24 into a longitudinal direction like the modification shown in FIG.15 and FIG.16. In this case, the fourth upper reinforcing member 24 includes a first reinforcing member 24A and a second reinforcing member 24B, and these reinforcing members 24A and 24B are joined by a joint member 35 (shown in FIG. 16). The first reinforcing member 24A has one bent portion 24b, and the second reinforcing member 24B also has one bent portion 24b. In this way, since each reinforcing member 24A, 24B has only one bent portion 24b, the springback of each reinforcing member 24A, 24B is reduced compared to the case where two or more bent portions are formed. As a result, the dimensional accuracy of the fourth upper reinforcing member 24 is improved.

ジョイント部材３５は柱状をなしており、一端部には第２補強材２４Bに差し込まれる差し込み部（結合部）３５ａが突設され、また、他端部には第１補強材２４Aに差し込まれる差し込み部（結合部）３５ａが突設されている。差し込み部３５ａの外周面と第２補強材２４Bの内周面との間、また、差し込み部３５ｂの外周面と第１補強材２４Aの内周面との間には、上述した製造誤差を許容するための空隙部（図示せず）が形成される。   The joint member 35 has a columnar shape, and an insertion portion (coupling portion) 35a to be inserted into the second reinforcement member 24B protrudes from one end portion, and an insertion portion to be inserted into the first reinforcement member 24A at the other end portion. A portion (joining portion) 35a is projected. The manufacturing error described above is allowed between the outer peripheral surface of the insertion portion 35a and the inner peripheral surface of the second reinforcing member 24B, and between the outer peripheral surface of the insertion portion 35b and the inner peripheral surface of the first reinforcing member 24A. A gap (not shown) is formed.

また、ジョイント部材３５の両側面には、それぞれストッパーとして機能するピン３５ｃが形成されている。このピン３５ｃに対応して第１補強材２４Ａの端部にはピン３５ｃが挿入可能な切欠部２４ｇ、２４ｇが形成され、第２補強材２４Ｂの端部にはピン３５ｃが挿入可能な切欠部２４ｆ、２４ｆが形成されている。尚、ピン３５ｃの代わりに、例えばフランジ等を設けてもよい。   Further, pins 35c functioning as stoppers are formed on both side surfaces of the joint member 35, respectively. Corresponding to the pin 35c, notches 24g, 24g into which the pin 35c can be inserted are formed at the end of the first reinforcing member 24A, and notches at which the pin 35c can be inserted into the end of the second reinforcing member 24B. 24f and 24f are formed. For example, a flange or the like may be provided instead of the pin 35c.

第１補強材２４Ａ及び第２補強材２４Ｂをジョイント部材３５で結合した状態では、ジョイント部材３５のピン３５ｃが切欠部２４ｆ、２４ｇに挿入されることになる。尚、図示しないが、第２上側補強材２２も第４上側補強材２４と同様な分割構造にすることができる。   In a state where the first reinforcing member 24A and the second reinforcing member 24B are coupled by the joint member 35, the pin 35c of the joint member 35 is inserted into the notches 24f and 24g. Although not shown, the second upper reinforcing member 22 can also have a divided structure similar to the fourth upper reinforcing member 24.

尚、上記実施形態では、第１〜第７下側補強材１１〜１７が押し出し成形された部材からなる場合について説明したが、これに限らず、プレス成形された部材であってもよいし、樹脂材４０よりも高強度の樹脂材からなるものであってもよい。   In addition, in the said embodiment, although the case where the 1st-7th lower reinforcement materials 11-17 consist of the member by which extrusion molding was carried out was demonstrated, not only this but the member by which press molding was carried out, It may be made of a resin material having a strength higher than that of the resin material 40.

上述の実施形態はあらゆる点で単なる例示に過ぎず、限定的に解釈してはならない。さらに、特許請求の範囲の均等範囲に属する変形や変更は、全て本発明の範囲内のものである。   The above-described embodiment is merely an example in all respects and should not be interpreted in a limited manner. Further, all modifications and changes belonging to the equivalent scope of the claims are within the scope of the present invention.
