Specific embodiment
It is specific embodiment of the utility model and with reference to attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
Each embodiment in the application is by taking the battery modules collectively formed by soft pack cell and hard shell battery core as an example, in this Shen
In embodiment please, width of the left and right directions in attached drawing 1 for cell 1c, bar shaped boss 2, soft pack cell and hard shell battery core is defined
Spend direction.
Embodiment one：
As shown in Figure 1, this battery case includes the box body 1 with inner cavity 1a, 1 upper end opening 1b of box body, the bottom surface of inner cavity 1a
On be equipped with several bar shaped boss 2 at equal intervals, it is hard for accommodating that above-mentioned inner cavity 1a is separated into several by several bar shaped boss 2
The cell 1c of shell battery core, 2 top of bar shaped boss can form the chamber for accommodating soft pack cell.
Specifically, as shown in Figures 2 and 3, the width of cell 1c is more than the width of bar shaped boss 2, in cell 1c
For installing hard shell battery core, it is used to that soft-package battery be installed in bar shaped boss 2, the section right angle of bar shaped boss 2 is triangular in shape, bar shaped
Boss 2 forms slope with cell 1c joints.The one side wall of bar shaped boss 2 sets to form oblique side with the inclined bottom surface of inner cavity 1a
Wall 2a, the plane perpendicular of another side wall and inner cavity 1a set to form perpendicular side wall 2b, the bottom surface of bar shaped boss 2 and the bottom surface of inner cavity 1a
Fitting.So perpendicular positioning surfaces of the side wall 2b as hard shell battery core, guide surfaces of the oblique side wall 2a as soft pack cell.Need what is illustrated
Be, this battery case in actual use, since mounted hard shell battery core or soft pack cell battery core can influence follow-up battery core
Installation, hard shell battery never installs the side of battery core and buckles and be adjacent to during installation, is the presence of lateral movement in this process, because
The width of this element lattice 1c is greater than the width of hard shell battery core, hard to ensure by setting certain surplus on cell 1c
Shell battery core entire hard shell battery core while on installation unit lattice 1c is in horizontality, and the width of bar shaped boss 2 is less than or waits
Width extra cell 1c is used to supplement the width of bar shaped boss 2 after the width of soft pack cell, installation.As further
It is preferred, the width summation of cell 1c and bar shaped boss 2 should be equal to or slightly less than soft pack cell and the width of hard shell battery core
Summation is spent, so as to fulfill fitting closely for soft pack cell and hard shell battery core.
Hard shell battery core is mounted in cell 1c during use, soft pack cell is mounted on 2 top of bar shaped boss, soft pack cell
With trend is drawn close to hard shell battery core, soft pack cell is so enable to recline with hard shell battery core closer, and hard shell battery core is not
Pressure can be applied to soft pack cell, that is, ensure that soft pack cell has good heat dissipation effect, and be avoided that hard shell battery core to Soft Roll
Battery core excessive compression, causes soft pack cell to damage.
Embodiment two：
In the present embodiment as shown in Figure 4, the other structures of battery case are identical with embodiment one, the difference is that：Bar shaped
The section of boss 2 is in isosceles triangle, and the two side of bar shaped boss 2 sets to form oblique side wall with the inclined bottom surface of inner cavity 1a
2a, the bottom surface of bar shaped boss 2 are bonded with the bottom surface of inner cavity 1a.Two oblique side wall 2a are as guide wall, to mounted on bar shaped boss
One guiding role of soft pack cell on 2, can abut against in the hard shell battery core in cell 1c, in addition hard shell
Battery core will not voluntarily deviate from after completing installation from bottom surface, therefore can play again and hard shell battery core is positioned.Need what is illustrated
It is that the width of bar shaped boss 2 can width wide with soft pack cell or twice soft pack cell.When the width of bar shaped boss 2
Degree can be wide with soft pack cell, and the centre of the bottom of Soft Roll is propped up by the top of bar shaped boss 2, forms positioning, soft pack cell
Both sides positioned respectively by hard shell battery core, this is well-located；During the width of the twice soft pack cell of width of bar shaped boss 2,
One soft pack cell can be set above two side walls respectively, and each soft pack cell is drawn close respectively to the hard shell battery core of respective side
And it reclines.
Embodiment three：
As shown in figure 5, the section of bar shaped boss 2 is square, the two side walls of bar shaped boss 2 are perpendicular to the bottom surface of inner cavity 1a
Form perpendicular side wall 2b.Two side walls can be born against on the side wall of battery core, for being positioned to battery core.As an optimization,
V-shaped groove 2c is offered along its length in the upper surface of bar shaped boss 2.Using this structure, soft pack cell can be with hard shell
Battery core mutually reclines, and hard shell battery core and soft pack cell will not squeeze between each other, positioning stablity.
The inner cavity 1a of box body 1 is separated into multiple cell 1c, each cell 1c by the utility model by bar shaped boss 2
It is interior to place hard shell battery core, and the hard shell battery core can be located in cell 1c, while 2 top of bar shaped boss also can
Corresponding soft pack cell is placed, is so arranged alternately, hard shell battery core and soft pack cell can mutually recline, and bar shaped boss 2
Hard shell battery core can be accurately positioned, hard shell battery core in cell 1c is made not generated to the soft pack cell in bar shaped boss 2
Degree squeezes.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Described specific embodiment can be done various modifications or additions or using similar by belonging to those skilled in the art
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
