Specific embodiment
Describe in detail according to battery case of the present utility model with reference to the accompanying drawings.
Referring to figs. 1 to Fig. 5, included according to battery case of the present utility model:Lower box 1;Lid 2, it is solid with the sealing of lower box 1
Fixed connection.The battery case also includes:Support arm 3, positioned at the lower section of lower box 1 and is fixed on lower box 1;Intensive aspect 4, is located at
Between support arm 3 and lower box 1 and at least with support arm 3 and lower box 1 in it is one of fixed.
In battery case of the present utility model, support arm 3 and intensive aspect 4 form anticollision and extrusion structure together, and outward
Support 3 can be used for providing the connection with the machinery (such as the automobile body B of vehicle) for installing battery case, so as to provide not only anti-collision
Hit and extrusion structure, and given full play to the structural behaviour of support arm 3 and intensive aspect 4.
For anticollision in horizontal direction all around and the consideration of extruding, in one embodiment, as shown in figure 1, outward
Support 3 is set around the whole periphery of lower box 1.Thus, it is possible to realize anticollision on the whole periphery of lower box 1 and squeeze
Pressure.
Support arm 3 is fixedly connected to form by multiple support arm beams 31.Each support arm beam 31 is punching press sheet metal component.
Referring to Figures 1 and 2, support 3 also includes:Bridge piece 32, two neighboring support arm beam 31 is fixedly connected.
For the only part anticollision in horizontal direction all around and extruding consideration, in another embodiment, outward
Support 3 is set along a part for the whole periphery of lower box 1.Thus, it is possible to realize there is pin on the portion perimeter of lower box 1
Anticollision and extruding to property.
In order to realize the fixation of support arm 3 and lower box 1, support arm 3 is by being fixedly welded on lower box 1, while may be used also
Support to lower box 1 is provided.
In order to realize the fixation of support arm 3 and the automobile body B of vehicle, as shown in Figure 6 and Figure 7, support arm 3 is provided with connecting hole
33, battery case also includes:The connecting hole 33 set on connector 5, with support arm 3 coordinates, by support arm 3 and the vehicle body of vehicle
B is fixed together.Wherein, connecting hole 33 can be screwed hole, and connector 5 can be bolt, screw.
Set around the whole periphery of lower box 1 with support arm 3 and matched, as shown in figure 1, intensive aspect 4 is around lower box 1
Whole periphery set.Intensive aspect 4 can be directly formed by fixedly connecting successively by multiple intensive aspect beams 41.
Set along a part for the whole periphery of lower box 1 with support arm 3 and matched, intensive aspect 4 is also corresponding with support arm 3
Ground is set along a part for the whole periphery of lower box 1.
According in battery case of the present utility model, intensive aspect 4 can be hollow structure.Because hollow structure itself can be carried
For big deformation, therefore can effectively to colliding and squeezing into row buffering.Wherein, intensive aspect beam 41 can be metal tube.
Metal tube can be steel pipe.
In order to provide effective anticollision and extruding, intensive aspect 4 at least with support arm 3 and lower box 1 in one of them
Fixed, then intensive aspect 4 is fixed with three kinds of modes, and the first is that intensive aspect 4 is fixed on support arm 3, and second is intensive aspect 4
It is fixed on lower box 1, the third is that intensive aspect 4 is fixed with support arm 3 and lower box 1, so that intensive aspect 4 and support arm 3
It is common to play collision and extruding protective action, wherein, fixed form can be welding.
In order to provide effective anticollision and extruding, as shown in figure 5 and figure 7, intensive aspect 4 is clamped in down in the horizontal direction
Two position Ph between casing 1 and support arm 3 stagger.This set, should when lower box 1 is subject to the extruding force of horizontal direction
Power path decomposes the stress of stress and vertical direction horizontally, so as to the extruding force of horizontal direction can be reduced, effectively drops
The deformation of low casing 1.Specifically, in Fig. 5 and Fig. 7, when battery case is subject to the extruding force of T1 directions (i.e. horizontal direction), lead to
Being transmitted to up to intensive aspect 4 of support arm 3 is crossed, is produced perpendicular to contact position at the position that support arm 3 and intensive aspect 4 are contacted
The extruding force in T2 directions, the extruding force in T2 directions can be analyzed to the pressure of horizontal direction t2 and the pressure of vertical direction t1, wherein,
The pressure of vertical direction t1 is directly transferred to the automobile body B of the vehicle being fixedly connected with support arm 3, so that the pressure of vertical direction t1
Absorbed without producing influence on battery case by the automobile body B of vehicle, the pressure that lower box 1 is subject to is the extruding force point in T2 directions
The pressure of the horizontal direction t2 after solution so that be applied to the pressure reduction of the horizontal direction of lower box 1.In order to strengthen anticollision and
Extruding, as shown in figure 5, intensive aspect 4 goes back in the vertical direction being clamped between lower box 1 and support arm 3.
In terms of material selection, lower box 1 is sheet metal component.Lid 2 is sheet metal component.When lower box 1 and lid 2 are metal plate
Part, can greatly mitigate the weight of battery case
Any suitable object is gone for according to battery case of the present utility model, such as object can be multiple battery moulds
Group or multiple batteries.When for multiple battery modules, multiple battery modules (can each have housing, it is also possible to percentage of batteries
Module portion has a housing and another part battery modules do not have housing) and battery case just constitute the battery bag of background technology,
When for multiple batteries, the battery modules that multiple batteries and battery case are just constituted.
