As shown in Figure 2, be provided with electrical equipment 13 in the front of battery pack 10.The battery component 11 of battery pack 10 is connected with electrical equipment 13.Electrical equipment 13 for example comprises the main relay of system, DC-DC conv, boost converter and current converter etc.The casing 12 of battery pack 10 is connected to one with the casing 14 of storage electrical equipment 13., the rear end part of the fore-end of the casing 12 of battery pack 10 and the casing 14 of electrical equipment 13 links together by connecting portion 15.
As shown in Figure 1, the casing 14 of electrical equipment 13 is arranged in the space being surrounded by floor tunnel 2, side bar 3 and crossbeam 4 and crossbeam 5., battery pack 10 and electrical equipment 13 are arranged on respectively in two spaces of arranging along vehicle commander's direction with the state that crossbeam 5 is clipped in the middle.The fore-end of the casing 14 of electrical equipment 13 and the rear side disposed adjacent of crossbeam 4, and the fore-end of casing 14 is by support 8 etc. and supported by crossbeam 4.The front side disposed adjacent of the rear end part of casing 14 and crossbeam 5, and the rear end part of casing 14 is supported by crossbeam 5 by support (not shown).In addition, the upside of the downside of connecting portion 15 to crossbeam 5.At the fore-end of the casing 14 of electrical equipment 13, be also provided with in the time of maintenance etc. for cutting off the connector 16 of supplying with from the electric power of battery pack 10.
As shown in Figures 1 and 2, the upside of the casing 12 of battery pack 10 and downside are respectively arranged with inlet plenum 21 and inlet plenum 22.The inlet plenum 21 that is arranged on casing 12 upsides is connected with airintake wind-tunnel 23.Be supplied to inlet plenum 21 from the admission port 23a leaked-in air of airintake wind-tunnel 23.The inlet plenum 22 that is arranged on casing 12 downsides is connected with blower fan 25 and airintake wind-tunnel 24.In the time that blower fan 25 moves, be supplied to inlet plenum 22 from the admission port 24a leaked-in air of airintake wind-tunnel 24.By means of the air that is supplied to inlet plenum 21 and inlet plenum 22, battery pack 10 is cooled.The air that is supplied to inlet plenum 21 and inlet plenum 22 drains into outside by exhausr port (not shown).The admission port 23a of airintake wind-tunnel 23, the admission port 24a of airintake wind-tunnel 24 and blower fan 25 are configured in, across floor tunnel 2 and with adjacent space, the space at battery pack 10 places in.
In present embodiment, as shown in Figure 3-Figure 5, at the two ends of the overall width direction of battery pack 10, be respectively arranged with the tension member 17 as tension member.Each tension member 17 is all identical members of cross-sectional plane in whole length (vehicle commander's direction), and be by by be separated by prescribed distance side by side parallel placement a pair of adapter plate 17c, be processed into the extended a pair of transverse slat 17b in outside of overall width direction and the longitudinal edge 17a that is connected between the leading section (long limit) of this pair of transverse slat 17b the member that one obtains respectively from the end, long limit of the opposite sides of this pair of adapter plate 17c.Tension member 17 is installed in, the centre portion (car body above-below direction) of the side plate 18 being fixedly connected with in the end (overall width direction) of the casing 12 of battery pack 10.In addition, the adapter plate 17c of tension member 17 is fixedly connected on side plate 18 by (not shown) such as bolts.Under this installing condition, between the longitudinal edge 17a of tension member 17 and a pair of transverse slat 17b and side plate 18, form space S 1.This space S 1 is extended along vehicle commander's direction.
The length L 2 in vehicle commander's direction is longer than the casing of battery pack 10 12 for the length L 1 of tension member 17 in vehicle commander's direction.Be installed under the state on side plate 18 at tension member 17, the front end of tension member 17 is than the front end of casing 12 outstanding specified length L3 forward; The rear end of tension member 17 is than the rear end of casing 12 outstanding specified length L4 backward.And the tension member 17 that is arranged on casing 12 left sides is adjacent with the right side of floor tunnel 2.The tension member 17 that is arranged on casing 12 right sides is adjacent with the left side of side bar 3.
The structure that adopts present embodiment, in the time that side collision (vehicle body side is collided) occurs vehicle 1, the tension member 17 that is arranged on the overall width direction two ends of battery pack 10 can deform, thus the collision load that side collision produces can be absorbed.Thus, the collision load that is delivered to battery pack 10 reduces because the distortion of tension member 17 absorbs, thereby battery pack 10 can be protected fully.
Conventionally,, in the time that right flank and the pillar etc. of vehicle 1 bump, likely because crossbeam 5,6 mitogenetic bendings are rotated battery pack 10, cause battery pack 10 and crossbeam 5,6 or floor tunnel 2 etc. to come in contact.But, the structure of employing present embodiment, due in vehicle commander's direction, the two ends of tension member 17 protrude from the end of battery pack 10, so the end of tension member 17 contacts with crossbeam 5,6 or floor tunnel 2 etc. than battery pack 10 is more first.Thus, can avoid battery pack 10 and crossbeam 5,6 or floor tunnel 2 come in contact and sustain damage.
In addition, the utility model is not limited to above-mentioned embodiment.For example, the cross sectional shape of tension member 17 is not limited to the shape shown in Fig. 4.As long as can form the space of extending along vehicle commander's direction by tension member 17 and side plate 18, can adopt various shapes.In addition, also can omit side plate 18, and tension member 17 is directly installed on to the end of the overall width direction of the casing 12 of battery pack 10.
In addition, in the above-described embodiment, be that situation between floor tunnel 2 and side bar 3 is illustrated to the allocation position of battery pack 10, but the utility model is not limited to this, the allocation position of battery pack 10 can change accordingly according to the size of structure, battery pack 10 under the floor of vehicle 1 etc.
