　　本発明は、車両に搭載した機器の保護に優れ、軽量化を図ることができる車両用保護ケース体の提供を目的とする。 An object of the present invention is to provide a protective case body for a vehicle that is excellent in protecting equipment mounted on a vehicle and can be reduced in weight.
　本発明に係る車両用保護ケース体は、一対の左フレーム及び右フレームと、一対の前フレーム及び後フレームとで、外枠体を形成し、前記外枠体の底部にフロアパネルを配置してあり、前記外枠体を構成する左右及び前後フレームのうち、少なくとも１つのフレームは車体への取付部を有し、前記取付部はフレームの縦壁から外側に向けて延在するとともに変形起点部を有していることを特徴とする。
　ここで、変形起点部は、外部からの負荷（入力）に対して変形する場合の起点となる部位をいう。 The vehicle protective case body according to the present invention includes a pair of left and right frames and a pair of front and rear frames forming an outer frame, and a floor panel is disposed at the bottom of the outer frame. And at least one of the left and right and front and rear frames constituting the outer frame body has a mounting portion to the vehicle body, and the mounting portion extends outward from the vertical wall of the frame and is a deformation starting point portion.

　取付部には、例えば左フレーム１２の取付部１２ｃに示すように、ボルト締結するための取付孔１２ｊを有する。
　前フレーム１３及び後フレーム１４は、ケース体を形成するための縦壁１３ａ，１４ａを有し、必要に応じて上片部１３ｃ，１４ｃ及び取付部１３ｂ，１４ｂを有する。 FIG. 1 shows an example in which a secondary battery (battery module) 1 is held (stored) in a holding portion 11 b inside a protective case body 10 and mounted under the floor of a vehicle body.
The right frame 11 and the left frame 12 each made of an aluminum extruded material are arranged to face each other, and the front and rear end portions thereof are connected by the front frame 13 and the rear frame 14 made of an aluminum extruded material, respectively, so that the outer frame body is It is formed.
For convenience of explanation, the left and right frames and the front and rear frames are described, but the mounting direction of the vehicle body is not limited.
A floor panel 15 is attached to the bottom of the outer frame.
The left and right frames 11 and 12 and the front and rear frames 13 and 14 have attachment portions to the vehicle body as required, and the example shown in FIG. 1 shows a cross-sectional end view taken along line AA in FIG. In addition, the attachment portions 11c and 12c are provided on the lower side of the vertical walls 11a and 12a of the right frame 11 and the left frame 12, respectively.
For example, as shown in the attachment portion 12c of the left frame 12, the attachment portion has an attachment hole 12j for bolt fastening.
The front frame 13 and the rear frame 14 have vertical walls 13a and 14a for forming a case body, and have upper pieces 13c and 14c and attachment portions 13b and 14b as necessary.
　フレームの断面構造の例を右フレーム１１のＡ－Ａ線断面端面図１（ｂ）にて説明する。
　右フレーム１１は、ケース体の収容部を形成するための縦壁１１ａを有し、その内側に電池モジュール（電池パック）１等の内部機器を保持させるための保持部１１ｂを有する。
　縦壁１１ａの外側には、上端側を外側に折り返した上片部１１ｉと、下側の基部１１ｆから外側に延在させた連結部１１ｄとその先に車両への取付部１１ｃを有する。
　連結部１１ｄは、縦壁側連結片１１１ｄと取付部側連結片２１１ｄとを途中で折り曲げたように連結してあり、この折り曲げ部を変形起点部１１ｅとした例になっている。
　図１に示した実施例は、縦壁側連結片１１１ｄに対して、取付部側連結片２１１ｄが上側に折り曲げるように変形起点部１１ｅを形成した例になっている。
　取付部１１ｃの連結部側には、縦壁１１ａに向けて突設した分岐状の突片部１１ｇを有し、これに対応させて縦壁１１ａの外側途中に突リブ状の規制部１１ｈを設けてある。 An example of the cross-sectional structure of the frame will be described with reference to FIG.
The right frame 11 has a vertical wall 11a for forming a housing portion for the case body, and a holding portion 11b for holding an internal device such as the battery module (battery pack) 1 inside thereof.
On the outer side of the vertical wall 11a, there are an upper piece portion 11i whose upper end is folded outward, a connecting portion 11d extending outward from the lower base portion 11f, and a mounting portion 11c for the vehicle at the tip.
The connecting portion 11d is an example in which the vertical wall side connecting piece 111d and the attaching portion side connecting piece 211d are connected so as to be bent in the middle, and this bent portion is used as a deformation starting point portion 11e.
The embodiment shown in FIG. 1 is an example in which the deformation starting point portion 11e is formed so that the attachment portion side connecting piece 211d is bent upward with respect to the vertical wall side connecting piece 111d.
On the connecting portion side of the mounting portion 11c, there is a branch-like protruding piece portion 11g protruding toward the vertical wall 11a, and a protruding rib-like restricting portion 11h is provided in the middle of the outer side of the vertical wall 11a correspondingly. It is provided.
　これにより、変形モードを図１（ｃ）に示すように、外側から矢印の方向にｆの入力があると、変形起点部１１ｅを起点として連結部１１ｄが折れ曲がるように取付部１１ｃが変形することで、外部からの入力エネルギーを吸収する。
　連結部１１ｄの変形が進行すると、突片部１１ｇが縦壁１１ａの外側に当たるが、突片部１１ｇの先端側が上方に開こうとする動きを突リブ状の規制部１１ｈにより抑制されるとともに、折れ曲がった連結部１１ｄと突片部１１ｇ及び縦壁１１ａにて中空断面形状を形成するようになり、断面剛性が向上し、それ以上変形するのを抑えるように作用する。 As a result, as shown in FIG. 1C, when the f is input from the outside in the direction of the arrow, the attachment portion 11c is deformed so that the connecting portion 11d is bent starting from the deformation starting point portion 11e. So, it absorbs external input energy.
As the deformation of the connecting portion 11d progresses, the projecting piece 11g hits the outside of the vertical wall 11a, and the movement of the projecting piece 11g to open upward is suppressed by the projecting rib-shaped restricting portion 11h. The bent connecting portion 11d, the protruding piece portion 11g, and the vertical wall 11a form a hollow cross-sectional shape, thereby improving the cross-sectional rigidity and acting to suppress further deformation.
　これに対して図２に示した第２の実施例は、連結部１１ｄを縦壁１１ａの外側の途中の基部１１ｆから下側に変形起点部１１ｅを介して折り曲げた例になっている。
　この場合には、突片部１１ｇを取付部１１ｃから下側に分岐するように設けることで、図２（ｂ）に示すように縦壁１１ａの下側に設けた規制部１１ｈにて突片部１１ｇが開くのを規制する。
　これにより、外部入力に対する変形モードを図２（ｂ）に示すように、連結部１１ｄが下側に折れ曲がるように変形することで、外部入力エネルギーを吸収し、連結部１１ｄが突片部１１ｇと縦壁１１ａとで中空断面形状を形成することで、その後の変形を抑える。 On the other hand, the second embodiment shown in FIG. 2 is an example in which the connecting portion 11d is bent from the base portion 11f in the middle of the outside of the vertical wall 11a to the lower side via the deformation starting point portion 11e.
In this case, by providing the protruding piece portion 11g so as to branch downward from the mounting portion 11c, as shown in FIG. 2B, the protruding piece is formed at the regulating portion 11h provided on the lower side of the vertical wall 11a. The part 11g is restricted from opening.
Thereby, as shown in FIG. 2B, the deformation mode for the external input is deformed so that the connecting portion 11d bends downward, so that the external input energy is absorbed, and the connecting portion 11d is connected to the protruding piece portion 11g. By forming a hollow cross-sectional shape with the vertical wall 11a, subsequent deformation is suppressed.
　このように、本発明に係る保護ケース体１０は、車体への取付部の変形を利用することで、いろいろな部位や方向から負荷された入力に対して、そのエネルギーを吸収するとともに、ある程度変形すると縦壁１１ａの外側に中空断面形状部を形成するようになり、変形に対する剛性が向上し、内部機器を有効に保護することができ、結果として保護ケース体の軽量化を図ることができる。 As described above, the protective case body 10 according to the present invention absorbs the energy with respect to the input loaded from various parts and directions by using the deformation of the mounting portion to the vehicle body, and deforms to some extent. Then, a hollow cross-sectional shape portion is formed outside the vertical wall 11a, the rigidity against deformation is improved, the internal device can be effectively protected, and as a result, the weight of the protective case body can be reduced.
　本発明に係る車両用保護ケース体は、外部からの負荷に対する保護効果に優れるので、車両に搭載する二次電池や各種機器の保護ケース体として利用できる。 Since the protective case body for vehicles according to the present invention is excellent in the effect of protecting against external loads, it can be used as a protective case body for secondary batteries and various devices mounted on the vehicle.
