Detailed Description
Referring to fig. 1, 2, 3, 4, 5 and 6, there are respectively an exploded perspective view of the battery module of the present utility model, an exploded front view of the battery module of the present utility model, a perspective view of the battery holder of the present utility model, a combined perspective view of the battery module of the present utility model, a combined front view of the battery module of the present utility model and a combined cross-sectional view of the battery module of the present utility model. First, as shown in fig. 1, 2 and 3, the battery module 100 of the present utility model includes a plurality of sets of battery holders 10. Each battery holder 10 includes a plurality of first sleeves 11, a plurality of second sleeves 13, and a plurality of battery receiving portions 15. Each battery accommodating portion 15 is disposed between the corresponding first sleeve 11 and the corresponding second sleeve 13, and is configured to accommodate a battery cell 20. One end of the battery cell 20 is fixed in the first sleeve 11, and the other end of the battery cell 20 is fixed in the second sleeve 13. The battery accommodating portion 15 has a partially hollowed-out structure, so that the battery cells 20 disposed in the battery accommodating portion 15 can dissipate heat through the hollowed-out structure during charge and discharge.
Furthermore, the battery module 100 of the present utility model further provides a plurality of positioning insertion holes 17. The positioning insertion holes 17 are provided on each group of the battery holders 10, respectively. In a preferred embodiment of the present utility model, each positioning receptacle 17 is disposed between corresponding adjacent first sleeves 11 or between corresponding adjacent second sleeves 13, respectively. In the present utility model, the first sleeve 11, the second sleeve 13 and the battery receiving portion 15 are disposed in a first direction (e.g. Z direction), the positioning insertion hole 17 is disposed in a second direction (e.g. Y direction) on the corresponding battery holder 10, and the second direction is perpendicular to the first direction. That is, if the battery holder 10 is laid on a horizontal plane (e.g., the inner surface of the casing), the positioning insertion holes 17 protrude upward or downward from the body structure of the battery holder 10.
With further reference to fig. 4, 5 and 6, the battery module 100 of the present utility model further provides a plurality of positioning pins (dowels) 30. When a plurality of battery holders 10 are to be assembled together, one end of each positioning pin 30 is aligned with a corresponding positioning jack 17 on one group of battery holders (such as the upper battery holder) 10, and the other end is aligned with a corresponding positioning jack 17 on the other group of battery holders (such as the lower battery holder) 10; then, one end of each positioning pin 30 is inserted into a corresponding positioning jack 17 on one group of the battery holders 10, and the other end is inserted into a corresponding positioning jack 17 on the other group of the battery holders 10. Thus, one of the battery holders 10 is stacked and positioned on the other battery holder 10 by vertical insertion and connection between the positioning pins 30 and the positioning insertion holes 17, so as to assemble the battery module 100.
In another embodiment of the present utility model, as shown in fig. 7 and 8, the battery module 100 further includes a housing 19. The battery holders 10 are disposed inside the casing 19 to prevent damage due to collision through protection of the casing 19. Furthermore, a plurality of positioning jacks 191 are provided on the inner surface of the housing 19. The plurality of positioning pins 30 are inserted between the plurality of positioning insertion holes 191 of the housing 19 and the plurality of positioning insertion holes 17 of the battery holder 10 to fix the battery module 100 on the housing 19.
In summary, through the design of the plugging structure of the positioning pins 30 and the positioning jacks 17, the battery module 100 of the present utility model can selectively assemble and stack a plurality of groups of battery holders 10 according to the actual battery capacity requirement. Furthermore, the battery holder 10 used in the battery module 100 of the present utility model is uniform in shape, so that the cost of the materials of the battery module manufacturer can be avoided.
The foregoing description is only one preferred embodiment of the present utility model and is not intended to limit the scope of the utility model, i.e., all equivalent variations and modifications in shape, construction, characteristics and spirit as defined in the claims are intended to be included in the scope of the present utility model.
