Referring to fig. 1, a schematic perspective view of a battery box according to the present utility model is representatively illustrated. In this exemplary embodiment, the battery box according to the present utility model is described as being applied to a vehicle-mounted battery. Those skilled in the art will readily appreciate that many modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below in order to adapt the relevant designs of the present utility model to other types of battery devices, and such changes are still within the principles of the battery case presented herein.
As shown in fig. 1, in an embodiment of the present utility model, a battery box according to the present utility model includes a frame 100 and a lifting lug 200. Referring to fig. 2 through 4 in combination, a schematic plan view of the battery box shown in fig. 1 is representatively illustrated in fig. 2; a cross-sectional view taken along line A-A in fig. 2 is representatively illustrated in fig. 3; an enlarged schematic of section B of fig. 3 is representatively illustrated in fig. 4. The structure, connection mode and functional relationship of the main components of the battery case according to the present utility model will be described in detail with reference to the above drawings.
As shown in fig. 1 to 3, in an embodiment of the present utility model, the frame 100 is used to enclose a cavity of a battery box, the cavity is used to accommodate a battery and an electrical component of a battery pack, and the cavity includes a battery compartment and an electrical compartment, for example. The lifting lug 200 is arranged on the outer side surface of the frame 100, which is back to the cavity, and the lifting lug 200 is used for lifting the battery pack. At least a portion of the frame 100 is formed by bending a first substrate, which may be, for example, a plate, and at least a portion of the lifting lug 200 is formed by bending a second substrate, which may be, for example, a plate. On this basis, the second thickness D2 of the second substrate is greater than the first thickness D1 of the first substrate. That is, the thickness of the second base body from which the lifting lug 200 is made is greater than the thickness of the first base body from which the rim 100 is made. Through the structural design, the utility model can solve the problem that the structural strength of the lifting lug 200 is insufficient due to the adoption of bending molding, and strengthen the structural strength of the lifting lug 200.
As shown in FIG. 3, in one embodiment of the present utility model, the ratio of the first thickness D1 of the first substrate to the second thickness D2 of the second substrate may be greater than or equal to 1/3 and less than 1, such as 1/3, 2/5, 1/2, 3/5, 9/10, etc. Through the structural design, the welding effect is poor due to uneven welding stress of the lifting lug 200 and the frame 100 in welding connection caused by overlarge thickness difference of the first substrate and the second substrate can be avoided, and in addition, when the thickness difference of the first substrate and the second substrate is overlarge, the frame 100 is easy to deform in the use process, so that the welding failure of the lifting lug 200 and the frame 100 is caused. Meanwhile, the utility model can avoid the problem that the effect of reinforcing the structural strength of the lifting lug 200 is not obvious enough due to the fact that the thickness difference of the first base body and the second base body is too small. In some embodiments, the ratio of the first thickness D1 of the first substrate to the second thickness D2 of the second substrate may be less than 1/3, such as 3/10, but not limited to this embodiment.
As shown in fig. 3, in an embodiment of the present utility model, the first thickness D1 of the first substrate may be 0.8mm to 3mm, for example, 0.8mm, 1mm, 2.5mm, 3mm, etc. Through the structural design, the utility model can avoid the overlarge weight caused by overlarge thickness D1 of the first substrate and overlarge thickness 2 of the second substrate, and can also avoid the failure of meeting the requirement on the structural strength of the frame 100 caused by overlarge thickness D1 of the first substrate. In some embodiments, the first thickness D1 of the first substrate may also be less than 0.8mm, or may be greater than 3mm, such as 0.79mm, 3.1mm, and the like, which is not limited to the present embodiment.
As shown in fig. 3, based on the structural design that the first thickness D1 of the first substrate is 0.8mm to 3mm, in an embodiment of the present utility model, the first thickness D1 of the first substrate may be further 1.2mm to 2mm, for example, 1.2mm, 1.5mm, 1.8mm, 2mm, etc.
As shown in fig. 3, in an embodiment of the present utility model, the second thickness D2 of the second substrate may be 1mm to 4mm, for example, 1mm, 1.2mm, 3.5mm, 4mm, etc. Through the structural design, the weight of the second substrate is prevented from being too large due to the fact that the second thickness D2 of the second substrate is too large, and meanwhile, the effect of reinforcing the structural strength of the lifting lug 200 is prevented from being insufficient due to the fact that the second thickness D2 of the second substrate is too small. In some embodiments, the second thickness D2 of the second substrate may be less than 1mm, or may be greater than 4mm, for example, 0.99mm, 4.1mm, etc., which is not limited to the present embodiment.
As shown in fig. 3, based on the structural design that the second thickness D2 of the second substrate is 1mm to 4mm, in an embodiment of the present utility model, the second thickness D2 of the second substrate may be further 1.5mm to 3mm, for example, 1.5mm, 2mm, 2.5mm, 3mm, etc.
As shown in fig. 3, in an embodiment of the present utility model, the frame 100 may be a structure with a cavity formed by bending a first substrate.
As shown in fig. 3, in an embodiment of the present utility model, the lifting lug 200 may be a structure having a cavity formed by bending a second substrate. It is understood that the lifting lug 200 herein may be a structure formed by bending and having a cavity, or may be a cavity formed by bending the second base body, or may be a cavity formed by matching the second base body after bending with other components of the battery case, including, but not limited to, the frame 100. Accordingly, the overall thickness of the lifting lug can be increased by adopting the design with the cavity, thereby facilitating lifting (such as facilitating arrangement of a lifting cylinder and other structures on the lifting lug or facilitating connection of the lifting appliance). However, the structure of the cavity may further cause the structural strength of the shackle 200 to be reduced. In this regard, the present utility model adopts a special design of the wall thickness of the lifting lug 200 (i.e., the thickness of the second substrate), so that the structural strength of the lifting lug 200 with the cavity can be ensured.
In an embodiment of the present utility model, the bending process of the first substrate may be roll forming.
In an embodiment of the present utility model, an arc-shaped transition structure may be formed at the bending portion of the frame 100.
In one embodiment of the present utility model, the thickness of the first substrate bent to form the frame 100 is smaller at the bending portion than at other positions.
As shown in fig. 4, in an embodiment of the utility model, the bending portion of the frame 100 may have a first R-angle structure 110, and the first R-angle structure 110 may be formed at the bending portion of the frame 100 during the roll forming process. Through the structural design, the stress state of the bending part of the frame 100 can be optimized by utilizing the first R-angle structure 110, so that the problem of stress concentration is avoided, and the structural strength of the frame 100 is further improved.
In an embodiment of the present utility model, the bending process of the second substrate may be roll forming.
In an embodiment of the present utility model, the bent portion of the lifting lug 200 may be formed with an arc-shaped transition structure.
In one embodiment of the utility model, the thickness of the second base bent to form the lifting lug 200 is smaller at the bending position than at other positions. Wherein, since the second base forms at least a part of the lifting lug 200 through bending, the material of the second base at the bending position is stretched and bent to reduce the thickness at the position, which further affects the structural strength of the lifting lug 200. In this regard, the present utility model adopts a special design of the wall thickness of the lifting lug 200 (i.e. the thickness of the second substrate), so as to ensure that the lifting lug 200 still has a sufficient structural thickness at the bending position, thereby ensuring the structural strength of the lifting lug 200, and in particular, is suitable for a design scheme of bending to form the lifting lug 200.
As shown in fig. 4, in an embodiment of the present utility model, the bending portion of the lifting lug 200 may have a second R-angle structure 210, and the second R-angle structure 210 may be formed at the bending portion of the lifting lug 200 during the roll forming process. Through the structural design, the stress state of the bending part of the lifting lug 200 can be optimized by utilizing the second R-angle structure 210, so that the problem of stress concentration is avoided, and the structural strength of the lifting lug 200 is further improved.
As shown in fig. 4, in an embodiment of the present utility model, when the frame 100 is formed by rolling a first substrate and the lifting lug 200 is formed by rolling a second substrate, and both the bending positions of the frame and the lifting lug 200 have R-angle structures, the second radius R2 of the corresponding circle of the second R-angle structure 210 at the bending position of the lifting lug 200 may be greater than the first radius R1 of the corresponding circle of the first R-angle structure 110 at the bending position of the frame 100. Through the above structural design, the second R-angle structure 210 with a larger corresponding radius can provide a more remarkable effect of optimizing the stress state, so that the utility model can make up for the problem of insufficient structural strength of the lifting lug 200 when the lifting lug 200 is formed by rolling, thereby further enhancing the structural strength of the lifting lug 200.

It should be clearly understood that the principles of the present utility model are in no way limited to any details or any components of the battery box shown in the drawings or described in this specification.

Through the structural design, the utility model can solve the problem that the structural strength of the lifting lug 200 is insufficient due to the adoption of bending molding, and strengthen the structural strength of the lifting lug 200.
