(deformation of side of sidewall portion when vehicle front side is collided)
In the battery fixing structure 2 involved by present embodiment, when front impact occurs for vehicle 1, front side vehicle frame 20 is produced
Deform and absorb impact, the deformation is in the horizontal plane 3 bendings, wherein including using the lower section of battery 10 as middle bending part
With the bending part being respectively present in before and after the bending part of the centre.Here, the rearward end of front side vehicle frame 20 is with along not shown
Instrument board lower member inclined plane mode, be more then obliquely installed more upward forwards, the pars intermedia of front side vehicle frame 20 and
Leading section is from described rearward end bending and is extended forwards in the horizontal plane.Therefore, when front side vehicle frame 20 is produced as at 3 points
During the deformation of bending, it may occur however that middle bending part is deformed in the way of swelling upward, the hook portion 62a of locking lever 62 is broken
Main bore portion 55a (being more particularly the rim bridge 55e between auxiliary hole portion 55b) situation.
As shown in Fig. 5 (b), the battery fixing structure 2 involved by present embodiment is drawn even in the hook portion 62a of locking lever 62
In the case of disconnected main bore portion 55a, because main bore portion 55a is connected with auxiliary hole portion 55b and be formed as a hole portion, and make hook portion
62a be locked to auxiliary hole portion 55b (more particularly, as auxiliary hole portion 55b upside entity part hooking sheet portion 55
Upper end 55f), flown out thus, it is possible to prevent battery 10 from departing from from battery tray 50 to outside car.
In the battery fixing structure 2 involved by embodiments of the present invention, due to the locking lever in battery press section 60
Auxiliary hole portion 55b is formed with above the main bore portion 55a that 62 hook portion 62a is locked, therefore, occurs front side even in vehicle 1
During collision etc. and in the case that hook portion 62a breaks main bore portion 55a, hook portion 62a can also be locked to auxiliary hole portion 55b, thus, it is possible to
Enough prevent battery 10 from departing from from battery tray 50 and being flown out to outside car.
In addition, in battery fixing structure 2, because main bore portion 55a is in more then width becomes narrower triangle upward
The hole portion of shape, therefore, it is possible to make hook portion 62a easily intert into main bore portion in the wide space of main bore portion 55a bottom
55a, and hook portion 62a can be effectively locked to the narrow positions on main bore portion 55a top by fastening of nut N etc..
Therefore, it is possible to realize the double effectses for the fixing intensity for improving locking operating efficiency and improving locking position.
In addition, in battery fixing structure 2, because auxiliary hole portion 55b is in the curved shape along main bore portion 55a upper limbs
Slit, therefore, it is possible to improve the durable tolerance of the fracture for main bore portion 55a by distractive load, even and if main aperture
Portion 55a is broken, due to being stretched in auxiliary hole portion 55b rising wood (that is, the upper end 55f in hooking sheet portion 55), therefore energy
Enough prevent fracture completely.
In addition, in battery fixing structure 2, due to hooking sheet 55 being positioned at using each positioning hole portion 52a, 55c, 55d
Sidewall body portion 52, and be fixed on the direction intersected with positioning hole portion 55c, 55d in many places, therefore, it is possible to improve
Installation accuracy, and the load effectively born upward can be realized.
In addition, in battery fixing structure 2, because power unit base is fixed in the front portion of battery tray 50 by bracket part 70
30, the rear portion of battery tray 50 is fixed on to the housing sidewall portion 41 of shock absorber casing 40 and the inner wall part 23 of front side vehicle frame 20, because
This, can reduce the component parts of bracket part 70, and can stably support the weight of battery 10.
Above by reference to accompanying drawing, embodiments of the present invention are explained, but the invention is not limited in this,
Appropriate change can be carried out without departing from the spirit and scope of the invention.
For example, hooking sheet portion 55 can also be pre-formed the structure being integrated for the bottom wall part 51 with battery tray 50.
In addition, the side of sidewall portion A for being formed with main bore portion 55a and auxiliary hole portion 55b is not limited to left and right (overall width direction) a pair, also may be used
It is set to front and rear a pair.
In addition, the main bore portion 55a width more upward that is shaped as becomes narrower, and there is corner in upper end, if but up and down
The size of direction size and the full-size in the direction vertical with the above-below direction than hook portion 62a is big, then is not limited to triangle
Shape, or diamond shape etc..
