It stretches.
Bottom surface side on floor 1 is provided with the crossbeam 11 of multiple reinforcements.Crossbeam 11 is extended along the width of the car, both ends
It is connect with side door sill.Crossbeam 11 is made of the component that section is hat, and a pair of flanges 11a is engaged with the bottom surface on floor 1.It is multiple
Crossbeam 11 configures with being separated by specified interval on vehicle commander direction.Here, crossbeam 11 is the one of " stiffener " of the utility model
Example.
In addition, being formed with multiple bolt-inserting hole 11b on crossbeam 11, each bolt-inserting hole 11b is provided with and its position
Set corresponding nut 12.Nut 12 is for example welded to the welded nut on crossbeam 11, is configured in the inner face side (face of crossbeam 11
Towards the side on floor 1).Multiple bolt-inserting hole 11b and multiple nuts 12 are configured as, and are separated by between regulation in the vehicle width direction
Every.
Battery 2 carries out electric power friendship between high voltage power supply, with the motor (illustration omitted) as vehicle driving driving source
It changes.That is, battery 2 is configured to, when motor is run as drive motor to the motor；When motor is as power generation
Machine saves the motor electricity when running.
Battery 2 includes multiple battery modules 21 and the box body 22 for accommodating these battery modules 21.Multiple battery modules 21 connect
It is connected together, each battery module 21 is configured on the specified position in box body 22.
Box body 22 is configured to the box-like with bottom plate 221.Multiple bolt-inserting hole 221a are formed on bottom plate 221.Respectively
Neck tube 23 is provided on the outside of bolt-inserting hole 221a.Neck tube 23 is configured to the cylindrical shape with central through hole 23a.Neck tube 23
It is arranged to, vertically extends (that is, the direction from the outer lateral edge of bottom plate 221 perpendicular to the bottom plate 221 extends), center is logical
Hole 23a and bolt-inserting hole 221a aligned in position, lower end are bonded on the outer surface of bottom plate 221, thereon end abutment
The bottom surface of crossbeam 11.That is, neck tube 23 is configured as, extend upwards from bottom plate 221 towards crossbeam 11.In addition, in neck tube 23
Configured with bolt 24, that is, the bolt 24 is from the central through hole 23a that bolt-inserting hole 221a is inserted into neck tube 23.Here, neck tube
23 be an example of the utility model " cylindrical component ".
When box body 22 is installed on floor 1, first by bolt-inserting hole 221a, the central through hole 23a and bolt of neck tube 23
The aligned in position of 24 position and bolt-inserting hole 11b and nut 12, then will be inserted in bolt-inserting hole 221a and neck tube 23
Central through hole 23a in bolt 24 be screwed into nut 12 from bolt-inserting hole 11b so that neck tube 23 upper end abut crossbeam
11 bottom surface and bolt 24 and nut 12 are fastenedly connected by 221 ground of bolt head 24a clamping bottom plate.Pass through bolt 24 and spiral shell as a result,
Mother 12, the bottom plate 221 of box body 22 is connect across neck tube 23 with crossbeam 11.
Box body 22 is installed to be as a result, is hung over below crossbeam 11 by neck tube 23.That is, box body 22 with its bottom surface 211 with
The state spaced apart of crossbeam 11 is mounted on crossbeam 11.
In the following, referring to Fig. 2, to the battery fastening structure 100 using present embodiment in the case where vehicle front occur touch
Situation when hitting is illustrated.
When head-on crash occurs for vehicle, as shown in Fig. 2, floor 1 is prevented to the movement of vehicle front (direction X1), and it is electric
It is still moved relative to floor 1 to vehicle front because of effect of inertia in pond 2.Therefore, in example shown in Fig. 2, crossbeam 11 and bottom plate 221
The part connecting with bolt 24 deforms respectively, also, the lower end of neck tube 23 and bolt 24 makes to vehicle front movement
Neck tube 23 and bolt 24 tilt.That is, when head-on crash occurs for vehicle, relative to floor 1, the bottom plate 221 of box body 22 is to before vehicle
Orientation is moved.Due to such deformation and displacement, collision energy when head-on crash is absorbed.
< beneficial effect >
In present embodiment, as described above, the box body 22 of battery 2 is mounted on the crossbeam 11 on floor 1 by neck tube 23
On, when head-on crash occurs for vehicle, box body 22 can be mobile to vehicle front relative to crossbeam 11, thus can absorb collision energy.
In other words, shock absorbing capability when vehicle frontal collision can be improved using battery fastening structure 100.
< other embodiment >
Above embodiment is the example to the various aspects of the utility model, cannot as limited explanation according to
According to.That is, the technical scope of the utility model is defined by the range that claims are recorded, and cannot be only according to above embodiment
To explain.In addition, the change in the meaning and range that are mutually equal with the record in claims of the utility model is equal
In the technical scope of the utility model.
For example, showing the example that box body 22 is mounted on crossbeam 11 by neck tube 23 in above embodiment, but this reality
With novel not limited to this, the structure on crossbeam can also be mounted on by the cylindrical component other than neck tube using box body.
In addition, showing the example for installing battery 2 on the crossbeam 11 on floor 1 in above embodiment, but this is practical new
Type is not limited to this, can also be in the case where the lower surface on floor is provided with the lower part stiffener extended along vehicle commander direction
Battery is mounted on the lower part stiffener.
In addition, when showing head-on crash in above embodiment crossbeam 11 and bottom plate 221 the portion being connect with bolt 24
The example point to deform, but not limited to this, when head-on crash is also likely to be that neck tube and bolt occur bending and deformation.
In addition, the both ends for showing the crossbeam 11 on floor 1 in above embodiment are connected to the example on side door sill, but this
Utility model is not limited to this, and the end of the crossbeam on floor can not also be connect with side door sill.That is, the end of crossbeam and side door sill
Between can separate.
