In one embodiment of the present disclosure, there is provided a case for an energy storage device, as shown in fig. 1, the case including:
the inner shell comprises a top plate 10 and a first annular side wall 11, wherein the top plate 10 is connected with one end of the first annular side wall 11 in a sealing mode.
The casing comprises a bottom plate 20 and a second annular side wall 21, wherein the bottom plate 20 is connected with one end of the second annular side wall 21 in a sealing mode. The second annular side wall 21 is at least partially fitted around the outside of the first annular side wall 11.
An insulating layer 3 is arranged between the first annular side wall 11 and the second annular side wall 21, and the first annular side wall 11 and the second annular side wall 21 are connected through the insulating layer 3 in a hot melting mode and form sealing.
In this embodiment, the insulating layer 3 connected between the first annular side wall 11 and the second annular side wall 21 is formed by heat fusion. The insulating layer 3 formed by heat capacity between the first annular side wall 11 and the second annular side wall 21 can be firmly connected with the first annular side wall 11 and the second annular side wall 21 without extruding the insulating layer 3 through the first annular side wall 11 and the second annular side wall 21, so that the structure of the insulating layer 3 is not affected, and the sealing effect and the insulating effect of the insulating layer 3 between the first annular side wall 11 and the second annular side wall 21 are guaranteed.
The insulating layer 3 is formed by hot-melting the assembled inner and outer shells. For example, a thermoplastic material is disposed between the first annular sidewall 11 and the second annular sidewall 21, and after the inner shell and the outer shell are assembled, the thermoplastic material is melted into a fluid and bonded together with the inner shell and the outer shell to form the insulating layer 3. The structure of the insulating layer 3 is not affected by the assembly of the inner shell and the outer shell, and the insulating effect and the sealing effect of the insulating layer 3 are improved.
For example, the thermoplastic material may be selected from plastic, rubber or silicone.
For example, the plastic may be polystyrene (PS plastic), polypropylene (PP plastic), Polyethylene (PE), polyamide (PA nylon plastic), polycarbonate (PC plastic), polyoxymethylene (POM plastic), fibers, polyvinyl chloride (PVC), fluoroplastic, or the like.
For example, during assembly of the housing, thermoplastic material is disposed between the first annular sidewall 11 and the second annular sidewall 21. The thermoplastic material is then processed by heat melting to form the insulating layer 3 between the first annular sidewall 11 and the second annular sidewall 21. For example, the temperature of the hot melt is selected in the range of 110 ℃ to 160 ℃. The preferred temperature of hot melt is 130 ℃.
Optionally, the top plate 10 forms a sealing connection with one end of the first annular side wall 11, so that the inner shell forms a cylindrical structure with an opening at one end. The bottom plate 20 forms a sealed connection with one end of the second annular side wall 21 so that the housing forms a cylindrical structure with one end open. The outer shell and the inner shell are assembled together into two cylindrical structures which are buckled together to form a sealed shell.
For example, the opening of the outer shell is sleeved on the opening of the inner shell, so that the second annular side wall 21 is at least partially sleeved on the outer side of the first annular side wall 11 to form a seal with the cylindrical structure formed by the inner shell, and the inner cavity of the shell is formed inside the cylindrical structure formed by the inner shell.
In one embodiment, as shown in fig. 1, the insulating layer 3 protrudes from an end of the second annular sidewall 21 away from the bottom plate 20.
In this embodiment, the insulating layer 3 protrudes from the second annular sidewall 21, which effectively forms an insulation at an end of the second annular sidewall 21 away from the bottom plate 20. This can prevent the end of the second annular side wall 21 from contacting the first annular side wall 11, improving the insulating effect.
In one embodiment, as shown in fig. 1, the insulating layer 3 covers an end of the first annular sidewall 11 away from the top plate 10.
In this embodiment the insulating layer 3 forms an insulating effect at the end of the first annular side wall 11 remote from the top plate 10. Referring to the orientation of fig. 1, the lower end of the first annular sidewall 11 is abutted against the bottom plate 20, and the insulating layer 3 covers the lower end position of the first annular sidewall 11 to further form insulation between the first annular sidewall 11 and the bottom plate 20. This can further improve the insulating effect of the insulating layer 3.
In one embodiment, as shown in fig. 2, the insulating layer 3 is integral with the outer surface of the first annular sidewall 11.
In this embodiment, the insulating layer 3 is formed integrally with the outer surface of the first annular side wall 11, so that the insulating layer 3 can be interposed between the first annular side wall 11 and the second annular side wall 21 only by completing the assembly between the inner casing and the outer casing in the process of assembling the inner casing and the outer casing. This simplifies the assembly process and facilitates the formation of the thermal fusion bond between the first annular side wall 11 and the second annular side wall 21 of the insulating layer 3.
For example, before assembling the inner and outer shells. The outer surface of the first annular side wall 11 is coated with a thermoplastic material. The thermoplastic material forms a hot melt connection between the first annular sidewall 11 and the second annular sidewall 21 by hot melting after the inner and outer shells are assembled. The insulating layer 3 formed by hot melting the thermoplastic material is sealed on the assembled shell, and can effectively form sealing and insulation between the first annular side wall 11 and the second annular side wall 21.
In one embodiment, as shown in fig. 3, the insulating layer 3 is integral with the inner surface of the second annular side wall 21.
In this embodiment, the insulating layer 3 is interposed between the first annular side wall 11 and the second annular side wall 21 by integrating the insulating layer 3 with the inner surface of the second annular side wall 21 so that only the assembly between the inner casing and the outer casing needs to be completed in the process of assembling the inner casing and the outer casing. This simplifies the assembly process and facilitates the formation of the thermal fusion bond between the first annular side wall 11 and the second annular side wall 21 of the insulating layer 3.
For example, before assembling the inner and outer shells. The inner surface of the second annular side wall 21 is coated with a thermoplastic material. The thermoplastic material forms a hot melt connection between the first annular sidewall 11 and the second annular sidewall 21 by hot melting after the inner and outer shells are assembled. The insulating layer 3 formed by hot melting the thermoplastic material is sealed on the assembled shell, and can effectively form sealing and insulation between the first annular side wall 11 and the second annular side wall 21.
In one embodiment, as shown in fig. 1, the insulating layer 3 includes a first insulating layer 31 and a second insulating layer 32, the first insulating layer 31 is formed integrally with the outer surface of the first annular sidewall 11, and the second insulating layer 32 is formed integrally with the inner surface of the second annular sidewall 21.
In this embodiment, the first insulating layer 31 on the outer surface of the first annular sidewall 11 and the second insulating layer 21 on the inner surface of the second annular sidewall 21 are used for forming a thermal fusion connection after thermal fusion.
After the inner shell and the outer shell are assembled together, the first insulating layer 31 and the second insulating layer 32 are attached together, and fluid formed by the first insulating layer 31 and the second insulating layer 32 forms hot melting connection between the first annular side wall 11 and the second annular side wall 21 through hot melting, so that sealing and insulating effects are achieved.
For example, before assembling the inner and outer shells, the outer surface of the first annular sidewall 11 and the inner surface of the second annular sidewall 21 are coated with a thermoplastic material. To form a first insulating layer 31 and a second insulating layer 32.
In one embodiment, as shown in fig. 1 and fig. 2, one end of the first insulating layer 31 protrudes from one end of the second annular sidewall 21 away from the bottom plate 20, and the other end of the first insulating layer 31 covers one end of the first annular sidewall 11 away from the top plate 10.
In this embodiment, the end of the first insulating layer 31 protruding from the second annular sidewall 21 away from the bottom plate 20 can form effective insulation at the upper end position of the second annular sidewall 21. The first insulating layer 31 covers a portion of the lower end of the first annular sidewall 11, enabling effective insulation between the first annular sidewall 11 and the bottom plate 20.
For example, when the thermoplastic material is applied to the first annular side wall 11, the height of the application is higher than the upper end position of the second annular side wall 21 after assembly. And the lower end face of the first annular side wall 11 is also coated with a thermoplastic material. This enables the first insulating layer 31 to be formed with more effective insulation.
In one embodiment, as shown in fig. 1 and 3, one end of the second insulating layer 32 covers one end of the second annular sidewall 21 away from the bottom plate 20, and the other end of the second insulating layer 32 extends to the bottom plate 20 and covers an area of the bottom plate 20 opposite to the first annular sidewall 11.
In this embodiment, the second insulating layer 32 covers the upper end of the second annular sidewall 21 to further enhance the insulating effect between the upper end position of the second annular sidewall 21 and the first annular sidewall 11. The second insulating layer 32 extends to the bottom plate 20 and covers a region of the bottom plate 20 opposite to the first annular side wall 11, which enables further insulation between the lower end of the first annular side wall 11 and the bottom plate 20 to improve the insulating effect.

In the embodiment, the shell of the energy storage device is good in sealing effect, and the insulation effect between the inner shell and the outer shell is better. The sealing effect and the insulating effect of the insulating layer 3 are not affected by the assembly.
