The connection can be accomplished by simply aligning the protrusion 101 with the card slot 102 and inserting the protrusion 101 into the card slot 102 without requiring a complicated fastening action. This will help to improve the assembly efficiency of the battery case 100, thereby improving the assembly efficiency of the battery 200.

Referring to fig. 3, in some embodiments, the protrusion 101 and the slot 102 are elongated, and the length of the protrusion 101 is parallel to the edge of the adjacent opening 110.

Specifically, the length of the protrusion 101 and the length of the card slot 102 may be the same or different. The length of the protrusion 101 may be less than or equal to the length of the body 10, and the length of the card slot 102 may be less than or equal to the length of the body 10.

In this way, the connection manner of the elongated protrusion 101 and the clamping groove 102 can more uniformly distribute connection pressure, and the protrusion 101 can better fit with the clamping groove 102 during connection, so that connection stability between the body 10 and the cover 20 is enhanced.

Referring to fig. 3, in some embodiments, the number of protrusions 101 on the same plate is one, and the plate is the side plate 14 or the side wall 23.

Specifically, in some embodiments, the number of protrusions 101 on the side plate 14 is one; in some embodiments, the number of protrusions 101 on the sidewall 23 is one.

Thus, the number of the protrusions 101 is defined as one and located on the same plate. This reduced construction reduces the complexity of the side panels 14 or side walls 23, thereby reducing the number of parts and manufacturing processes. The simplified structural design contributes to an improvement in the manufacturing efficiency of the battery case 100 and a reduction in the production cost.

Referring to fig. 3, in some embodiments, the protrusion 101 extends from a first end of the plate to a second end opposite the first end.

Specifically, the structure of the protrusions 101 on the panel (side panel 14 or side wall 23) extends from a first end thereof until reaching a second end of the panel such that the protrusions 101 span the entire panel.

Thus, the first end and the second end can be firmly connected by matching the protrusion 101 with the clamping groove 102, the connection range of the protrusion 101 is wider, and the connection effect is more stable and reliable.

Referring to fig. 3, in some embodiments, the protrusions 101 are profiling of the side plates 14 and/or side walls 23; and/or the clamping groove 102 is profiled for the side plate 14 and/or the side wall 23.

Specifically, profiling is a manufacturing process that shapes a material into a desired shape by applying pressure to the material. In some embodiments, the protrusions 101 are profiling of the side plates 14; in some embodiments, the protrusions 101 are profiling of the side walls 23; in some embodiments, the protrusions 101 are profiling of the side plates 14 and side walls 23.

In some embodiments, the card slot 102 is a profiling of the side plate 14; in some embodiments, the card slot 102 is profiled of the side wall 23; in some embodiments, the card slot 102 is a profiling of the side plate 14 and side wall 23.

In this manner, since the protrusions 101 and/or the card slots 102 are formed by the profiling process, they can be integrally formed with the side plate 14 and/or the side wall 23 without an additional assembly process. The integrally formed connection can improve the overall strength and stability of the battery case 100 and reduce potential loosening problems caused by the assembly process.

Referring to fig. 3, 6 and 7, fig. 6 is a schematic structural view of a battery 200 according to some embodiments of the present utility model, and fig. 7 is a cross-sectional view of the battery 200 in A-A direction of fig. 6. In certain embodiments, the battery case 100 includes a plurality of fasteners 30, the plurality of fasteners 30 connecting edges of the side plates 14 and the cover plate 22.

Specifically, the fastener 30 is a component for connecting different parts, such as a bolt, a screw, or the like. The number of fasteners 30 may be two, three, four or even more.

In this manner, the multi-point connection can enhance the connection stability of the battery case 100 by connecting the edges of the side plates 14 and the cover plate 22 using the plurality of fasteners 30. The plurality of fasteners 30 may more evenly distribute the connection pressure than a single connection point, thereby ensuring firm connection and less loosening of the battery case 100.

Referring to fig. 3, in some embodiments, the plurality of fasteners 30 are spaced apart along the circumference of the cover 22, the cover 22 includes a first edge 220 and a second edge 221 connected to the first edge 220, the sidewall 23 connected to the first edge 220 is provided with a second snap feature 21, and the number of fasteners 30 on the first edge 220 is less than the number of fasteners 30 on the second edge 221.

Specifically, the plurality of fasteners 30 may be equally spaced or unequally spaced along the circumferential direction of the cover plate 22, and may be specifically configured as desired. Since the side wall 23 connected to the first edge 220 is provided with the second snap-in structure 21, the connection to the side panel 14 at the first edge 220 is a snap-in connection, which secures the connection between the first edge 220 and the side panel 14, and thus no more fasteners 30 need to be provided, and thus the number of fasteners 30 on the first edge 220 is less than the number of fasteners 30 on the second edge 221.

In this manner, the connection stability of the battery case 100 is enhanced by the plurality of fasteners 30 arranged at intervals along the circumferential direction of the cap plate 22. The uniform distribution of the plurality of fasteners 30 allows the coupling pressure to be more uniformly transferred between the cover plate 22 and the side walls 23, thereby increasing the number of coupling points and improving the overall stability of the battery case 100.

Further, since the side wall 23 connected to the first edge 220 is provided with the second fastening structure 21, the cover 22 can be tightly fastened to the side wall 23 by the fastening structure, so that the number of fasteners 30 on the first edge 220 can be reduced, thereby improving the assembly efficiency of the battery 200.

Referring to fig. 3, in some embodiments, the length of the first edge 220 is greater than the length of the second edge 221.

Specifically, taking an example in which the shape of the cover plate 22 is rectangular, the first edge 220 may be a long side of the rectangle, and the second edge 221 may be a short side of the rectangle. When the length of the first edge 220 is greater than the length of the second edge 221, the rectangular long side portions can be connected by snap-fit connection, and thus the number of fasteners 30 to be used at the long side portions is small, so that the assembly can be completed more rapidly.

In this way, since the side wall 23 connected to the first edge 220 is provided with the second fastening structure 21, the cover 22 can be tightly fastened to the side wall 23 by the fastening structure. The length of the first edge 220 is set to be greater than the length of the second edge 221 so that a longer portion of the cover 22 can be connected by a snap-fit arrangement, which is more efficient, and a shorter portion of the cover 22 can be connected by the fastener 30, which is more stable.

In other embodiments, the length of the first edge 220 is less than the length of the second edge 221. The first catch structure 12 and the second catch structure 21 at this point are still in mating connection at the first edge 220.

Referring to fig. 3, 8 and 9, fig. 8 is an enlarged view of a portion B of fig. 7, and fig. 9 is a schematic structural view of a seal 40 according to some embodiments of the present utility model. In certain embodiments, the battery case 100 includes a seal 40, the seal 40 being disposed between the body 10 and the cover 20, the seal 40 being disposed around the opening 110 and sealing the gap between the body 10 and the cover 20.

Specifically, the sealing member 40 is a member for preventing liquid, gas, solid particles, or the like from entering or leaking from the opening 110 of the battery case 100. By sealing the gap between the body 10 and the cover 20, the sealing member 40 can prevent the entry of external impurities and also prevent the leakage of substances inside the battery. The maximum profile dimension of the seal 40 is less than or equal to the minimum profile dimension of the cover 20. The sealing member 40 may be a frame type structure, an edge of the sealing member 40 may be covered on the body 10, and the edge of the sealing member 40 may be provided with a through hole through which the fastener 30 passes.

The sealing member 40, the body 10 and the cover 20 can be connected by the fastening member 30, and the sealing member 40, the body 10 and the cover 20 are provided with corresponding fastening member 30 hole sites. The sealing member 40, the body 10 and the cover 20 can be connected through the first fastening structure 12 and the second fastening structure 21 in a matched manner, so that the number of fasteners 30 required in assembly is reduced, and the assembly efficiency is improved.

In this way, the sealing member 40 can effectively seal the battery case 100, prevent leakage of electrolyte and other components inside the battery 200, and simultaneously prevent external dust, moisture or other contaminants from entering the battery case 100, thereby improving the service life and stability of the battery 200.

To ensure the amount of deformation of the seal 40, both the fastener 30 and the snap-in structure are required. It will be appreciated that the snap features are provided in a longer connection area. For example, the body 10 and the cover 20 are rectangular in shape, the connection areas of the body 10 and the cover 20 are long sides and short sides of the corresponding rectangles, the fastening structure is disposed on the long sides, and the fastening member 30 is disposed on the short sides. In this way, the fasteners 30 can be used as little as possible, so that the assembly efficiency can be improved.

In a specific embodiment, according to the rigidity of the cover 20, the first fastening structure 12 located on the body 10 and the second fastening structure 21 located on the cover 20 are matched by applying pressure, so as to complete the fastening between the body 10 and the cover 20.

Further, fasteners 30 are provided at corresponding positions of the cover 20, the sealing member 40 and the body 10 to complete the assembly of the battery case 100.
