図２に戻って前記部品搭載フレーム２の後方側には、モータルーム１と車室内１６を仕切るダッシュパネル１７が配設されている。 A battery suspension member 14 is provided between the floor side members 4 behind the cross member 13 on the vehicle body, and a front end portion 15a of a battery mounting portion 15 for mounting a battery is attached to the battery suspension member 14 It is done. The rear side of the battery mounting portion 15 is supported to the rear side of the vehicle body via a plurality of battery suspension members (not shown) provided between the floor side members 4.
Referring back to FIG. 2, on the rear side of the component mounting frame 2, a dash panel 17 for partitioning the motor room 1 and the passenger compartment 16 is disposed.

上記電動車両の車体構造で、前方から過大な衝撃荷重が加わった時の作用を説明する。
車体のモータルーム１内に前後方向にレイアウトされている変速機１１が、前方からの過大な衝撃荷重によって、車体後方に移動するとき、下方視で、フロントサスペンションフレーム５の前方に設けられている凹形状部５ｃに変速機１１が接触することがある。こうして、変速機１１はフロントサスペンションフレーム５の凹形状部５ｃのどこかに係止されて後方への移動が阻止される。このとき、フロアサイドメンバ４相互間に取り付けられているクロスメンバ１３が荷重を受けてフロントサスペンションフレーム５の後退および変速機１１の後退を低減する。クロスメンバ１３は、図示しないセンタトンネルを横断して設けられており、センタトンネルの形状維持にも貢献することができる。また、クロスメンバ１３の後方に電池懸架メンバ１４が設けられているので、前方からの衝撃荷重をフロントサスペンションフレーム５が結合されたフロアサイドメンバ４の前方側で受け止め、この前方からの荷重を更に後方に伝達して分散する。このとき、フロアサイドメンバ４は、前方側で互いに接近するような構造に構成されていることから、フロアサイドメンバ４相互が内側に倒れて、荷重が車体後方に伝達できない場合が考えられる。これを電池懸架メンバ１４で支えることで、フロアサイドメンバ４の倒れを低減することができる。 The operation of the above-described vehicle body structure of the electric vehicle when an excessive impact load is applied from the front will be described.
The transmission 11, which is laid out in the front-rear direction in the motor room 1 of the vehicle body, is provided on the front of the front suspension frame 5 as viewed from below when it is moved backwards by the excessive impact load from the front. The transmission 11 may contact the concave portion 5c. Thus, the transmission 11 is locked somewhere on the concave portion 5c of the front suspension frame 5 to prevent its backward movement. At this time, the cross member 13 attached between the floor side members 4 receives a load to reduce the backward movement of the front suspension frame 5 and the backward movement of the transmission 11. The cross member 13 is provided across the center tunnel (not shown), and can also contribute to the shape maintenance of the center tunnel. Further, since the battery suspension member 14 is provided at the rear of the cross member 13, the impact load from the front is received by the front side of the floor side member 4 to which the front suspension frame 5 is coupled, and the load from the front is further added. Transmit backward and disperse. At this time, since the floor side members 4 are configured to be close to each other on the front side, there is a possibility that the floor side members 4 may fall inward and the load can not be transmitted to the rear of the vehicle body. By supporting this by the battery suspension member 14, the falling of the floor side member 4 can be reduced.

また、車体前方からの荷重が前車輪６のタイヤに加わると、車輪懸架アーム７を介してフロントサスペンションフレーム５に伝達され、フロントサスペンションフレーム５のフロアサイドメンバ４への懸架点に伝達される。車体の変形が進むと、前車輪６はサイドシル部９に接触するので、サイドシル部９に荷重が分散される。また、フロアサイドメンバ４、フロントサスペンションフレーム５への荷重の一部は、補強用のブレース１０を介してサイドシル９に分散される。   Further, when a load from the front of the vehicle body is applied to the tire of the front wheel 6, it is transmitted to the front suspension frame 5 via the wheel suspension arm 7 and transmitted to the suspension point of the front suspension frame 5 to the floor side member 4. When the deformation of the vehicle body progresses, the front wheel 6 contacts the side sill portion 9, so the load is dispersed to the side sill portion 9. Further, a part of the load on the floor side member 4 and the front suspension frame 5 is dispersed to the side sill 9 through the reinforcement brace 10.

前記実施の形態によれば、車体前方からの衝撃荷重に対して変速機１１が後方に移動した場合、フロントサスペンションフレーム５の前方に設けられている凹形状部５ｃに変速機１１が接触することがある。こうしてフロントサスペンションフレーム５の凹形状部５ｃに係止されて後方への移動が低減されるので、変速機１１およびフロントサスペンションフレーム５の後方への移動に伴うダッシュパネル１７に対する損傷が防止される。
このとき、フロントサスペンションフレーム５の後方側に後方に向けて凸形状に構成したクロスメンバ１３が前記フロアサイドメンバ４に取り付けられているので、このクロスメンバ１３が荷重を受けてフロントサスペンションフレーム５の後退および変速機の後退を低減することができる。 According to the above-described embodiment, when the transmission 11 moves rearward with respect to an impact load from the front of the vehicle body, the transmission 11 contacts the concave portion 5 c provided on the front of the front suspension frame 5. There is. In this way, since it is locked by the concave shaped portion 5c of the front suspension frame 5 and the rearward movement is reduced, damage to the dash panel 17 accompanying the rearward movement of the transmission 11 and the front suspension frame 5 is prevented.
At this time, since the cross member 13 having a convex shape is attached to the rear side of the front suspension frame 5 in a convex shape toward the rear, the cross member 13 receives a load and the front suspension frame 5 is The reverse and reverse of the transmission can be reduced.

前記フロントサスペンションフレーム５の後方側には、凹形状部５ｃと同様の凹形状部５ｄが形成されており、この凹形状部５ｄと対向するようにクロスメンバ１３の車体前方側には凹形状部１３ｂが形成されている。
前記フロントサスペンションフレームの懸架点と前記クロスメンバ１３の懸架点が隣接して設けられているので、凹形状部１３ｂと凹形状部５ｄによって枠構造Ｓが形成され、剛性の向上を図ることができる。
前記左右のフロアサイドメンバ４の前端部からサイドシル部９にかけて補強ブレース１０が設けられているので、フロアサイドメンバ４、フロントサスペンションフレーム５への荷重の一部は、補強ブレース１０を介してサイドシル部９に荷重分散することができる。 A recessed portion 5d similar to the recessed portion 5c is formed on the rear side of the front suspension frame 5, and the recessed portion on the vehicle front side of the cross member 13 is opposed to the recessed portion 5d. 13b is formed.
Since the suspension point of the front suspension frame and the suspension point of the cross member 13 are provided adjacent to each other, the concave portion 13b and the concave portion 5d form the frame structure S, and the rigidity can be improved. .
Since the reinforcement brace 10 is provided from the front end of the left and right floor side members 4 to the side sill portion 9, part of the load on the floor side member 4 and the front suspension frame 5 is the side sill portion via the reinforcement brace 10 The load can be distributed to nine.

本発明は、上記実施の形態のみに限定されるものではなく、例えば、変速機１１が設けられた側のフロントサスペンションフレーム５の懸架のみを荷重入力に起因して解放する機構を設け、こちら側（実施例では車両左側）の荷重を、車輪懸架アーム７からサイドシル９に流して分散することができる。フロアサイドメンバ４前部にクロスメンバ１３を接続したので、フロアサイドメンバ４からクロスメンバ１３に荷重を流すことができることから、モータ１２と変速機１１によるダッシュパネル１７への荷重を軽減することもできる。その他、本発明の技術的範囲を変更することなく、適宜変更して実施し得ることは言うまでもない。   The present invention is not limited to the above embodiment. For example, a mechanism for releasing only the suspension of the front suspension frame 5 on the side provided with the transmission 11 due to load input is provided. The load (in the embodiment, the left side of the vehicle) can flow from the wheel suspension arm 7 to the side sill 9 to be dispersed. Since the cross member 13 is connected to the front of the floor side member 4, a load can be flowed from the floor side member 4 to the cross member 13, so the load on the dash panel 17 by the motor 12 and the transmission 11 can be reduced. it can. It goes without saying that the present invention can be modified as appropriate without changing the technical scope of the present invention.
