[0038] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0039] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0040] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0041] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0043] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0044] In related technologies, different compartments are separated without being sealed, or sealed using local components such as wire loops or through-wall terminals. This sealing structure is not tight enough, resulting in gaps in the structure. When the battery thermally runs away, it will generate a large amount of high-temperature smoke, which may contain corrosive gases and particulate matter. If this smoke enters the PCS compartment through the gaps, it will corrode or contaminate the sensitive electronic components inside the PCS, leading to equipment failure, electrical short circuits, or even more serious accidents such as fires.

[0045] See Figure 1 , Figure 1 A schematic diagram of the installation of the sealing assembly in one embodiment of this application is shown. The housing 1 is shown in one embodiment of this application. For an integrated energy storage unit, after the first housing 10 is connected to the second housing 20, the first partition 30 and the second partition 23 are used to separate the battery compartment and the power compartment.

[0046] A sealing component 100 provided in one embodiment of this application includes a sealing component 100 disposed between a first partition 30 and a second shell 20. When the first shell 10 covers the second shell 20, the sealing component 100 can be deformed by force along a first direction, the first direction being the direction from the second shell to the first shell.

[0047] One embodiment of the housing includes a first shell 10, a second shell 20, and a sealing assembly 100. The second shell 20 and the first shell 10 can be connected to form an outer shell. The first shell 10 is provided with a first partition 30, and the second shell 20 is provided with a second partition 23. The first partition 30 has at least one groove or protrusion, and the second partition 23 has at least one groove or protrusion that matches the first partition 30. After the first shell 10 is connected to the second shell 20, the first partition 30 and the second partition 23 are used to separate a first compartment 21 and a second compartment 22.

[0048] The housing 1 can be the outer shell of an integrated energy storage unit, or it can be the outer shell of a battery pack. The following description uses the housing 1 as the outer shell of an integrated energy storage unit as an example. An embodiment of the integrated energy storage unit of this application includes a first shell 10, a second shell 20, and a sealing assembly 100. The second shell 20 and the first shell 10 can be connected to form an outer shell. The first shell 10 has a first partition 30, and the second shell 20 has a second partition 23. The first partition 30 has at least one groove or protrusion, and the second partition 23 has at least one groove or protrusion that matches the first partition 30. After the first shell 10 is connected to the second shell 20, the first partition 30 and the second partition 23 serve to separate the battery compartment and the power compartment.

[0049] The aforementioned sealing component 100, housing 1, and energy storage unit all feature a sealing component 100 that deforms under force when the first housing 10 is closed. This deformation better fills the gap between the first partition 30 and the second housing 20, enhancing the sealing effect and preventing harmful gases from the battery compartment from leaking into the power compartment 22. The deformation characteristics of the sealing component 100 allow it to adapt to minor unevenness or dimensional deviations between the first partition 30 and the second housing 20, making it more suitable for first partitions 30 of various shapes and structures, especially those with irregular edges such as grooves or protrusions, ensuring reliable sealing. The sealing component 100 also acts as a buffer under force, reducing the impact when the first housing 10 is closed, protecting the first partition 30 and the second housing 20, and extending their service life. As a sealing element, the sealing component 100 simplifies the installation process, achieving effective sealing without complex adjustments, thus reducing the difficulty of installation and maintenance.

[0050] See Figure 2 , Figure 3 As shown, Figure 2 , 3 A cross-sectional view of the housing according to one embodiment of this application is shown. In one embodiment, the sealing assembly 100 is disposed between the first partition 30 and the second partition 23, the second partition 23 having at least one groove or protrusion that mates with the first partition 30. In one embodiment, the edge of the first partition 30 includes a recessed clearance groove, and the sealing assembly is bent to fit against the clearance groove.

[0051] Specifically, the second partition 23 and the first partition 30 are located in the same vertical plane. The second shell 20 and the first shell 10 enclose a receiving cavity. The second partition 23, the sealing assembly 100, and the first partition 30 together divide the receiving cavity into a first compartment 21 and a second compartment 22. The second partition 23 and the first partition 30 are straight or irregular in shape. The second partition 23 has at least one groove or protrusion, and correspondingly, the first partition 30 also has at least one groove or protrusion. The position of the groove or protrusion corresponds to the protrusion or groove of the second partition 23, so as to form a complete and airtight partition structure.

[0052] like Figure 2 , Figure 3 As shown, in this embodiment, the second partition 23 has a protrusion formed by a sealing device 24 disposed on the second partition 23. The sealing device 24 is used to seal the cable or busbar passing between the first compartment 21 and the second compartment 22. The edge of the first partition 30 includes a recessed clearance groove, which corresponds to the shape of the sealing device 24. After the first housing 10 is closed, the clearance groove and the sealing assembly 100 disposed at the clearance groove abut against the upper edge of the sealing device 24, and the lower edge of the sealing device 24 is fixed to the second partition 23.

[0053] In other embodiments, the second shell 20 is provided with a second partition 23, and / or the first shell 10 is provided with a first partition 30, that is, at least one of the second partition 23 and the first partition 30 is provided. When only one of the second partition 23 and the first partition 30 is provided, the second partition 23 directly abuts against the first shell 10 through the sealing assembly 100, or the first partition 30 directly abuts against the second shell 20 through the sealing assembly 100. The first partition 30 and the second partition 23 are used to separate the first compartment 21 and the second compartment 22.

[0054] In one embodiment, the projection of the groove or protrusion onto the plane of the first partition 30 is trapezoidal. Furthermore, the width of the sealing device 24 increases towards the second partition 23. The overall shape of the sealing device 24 is trapezoidal, with a narrower upper edge and a wider lower edge. The beveled edges on both sides allow for a more suitable bending angle of the sealing assembly 100, resulting in a better fit to the sealing device 24. The upper edge of the sealing device 24 may have a chamfered structure, improving the fit of the sealing assembly 100 at the bends of the outer contour of the sealing device 24.

[0055] In one embodiment, the sealing component 100 is made of silicone or rubber. Silicone is a porous material filled with microbubbles, possessing excellent elasticity and flexibility. It can deform under external force and return to its original shape after the force is removed. Silicone maintains stable physical properties in high-temperature (typically above 200°C) and low-temperature (below -50°C) environments, and has good resistance to most chemical substances (such as acids, alkalis, solvents, etc.), is not easily corroded or aged, and has good electrical insulation properties.

[0056] like Figure 3 , 4 As shown, in one embodiment, the deformation of the sealing assembly 100 in the first direction is 1-10 mm, = in the first direction as... Figure 4 In the X direction. Specifically, after the first shell 10 is closed, the distance between the first partition 30 and the second shell 20 (second partition 23) is less than the longitudinal height of the portion of the sealing assembly 100 located between the first partition 30 and the second shell 20. The difference between the distance between the first partition 30 and the second shell 20 (second partition 23) and the longitudinal height of the portion of the sealing assembly 100 located between the first partition 30 and the second shell 20 is 1-10mm, causing deformation of the portion of the sealing assembly 100 located between the first partition 30 and the second shell 20 after the first shell 10 is closed. The deformation in the first direction is 1-10mm. Preferably, the deformation of the sealing assembly 100 in the first direction is 2mm, 3mm, 4mm, 5mm, etc. When the sealing assembly 100 is made of silicone or rubber, the maximum value of the deformation in a single direction of this material can be greater than 10mm.

[0057] See Figure 4 , Figure 5 As shown, Figure 4 , 5 A schematic diagram of a sealing assembly according to one embodiment of this application is shown. In one embodiment, the sealing assembly 100 has a hollow cavity 121 inside, which is capable of shrinking along the first direction. The hollow cavity 121 is located between the first partition 30 and the second shell, or between the first partition 30 and the second partition 23, and the shrinking of the hollow cavity 121 along the first direction allows the sealing assembly to deform.

[0058] In one embodiment, the sealing assembly 100 includes a pressure-receiving portion 120 disposed at the edge of the first partition 30, the pressure-receiving portion 120 being capable of deformation under force in a first direction.

[0059] In one embodiment, the sealing assembly 100 includes a fitting portion 110, which is integrally formed with the pressure-receiving portion 120, and the fitting portion 110 is fitted to the first partition 30. Specifically, the fitting portion 110 extends along the extending direction of the first partition 30 and wraps around the edge of the first partition 30. Specifically, the pressure-receiving portion 120 has a hollow cavity 121 inside, which extends along the longitudinal direction of the sealing assembly 100, and the longitudinal direction is defined as the extending direction at the connection between the pressure-receiving portion 120 and the fitting portion 110, such as... Figure 4 The hollow cavity 121 structure reduces the overall stiffness of the pressure-bearing part 120, making it more susceptible to deformation under external forces. Under pressure, the hollow cavity 121 allows the pressure to be transmitted more evenly throughout the pressure-bearing part 120, thereby improving the reliability and consistency of the seal. The hollow cavity 121 structure can evenly distribute external pressure, avoid stress concentration, and reduce the risk of local excessive deformation or damage. The hollow cavity 121 structure reduces the amount of material used in the pressure-bearing part 120, lowering manufacturing costs. This design also reduces the weight of the pressure-bearing part 120.

[0060] Specifically, the hollow cavity 121 is cylindrical or elliptical, forming a pressure-bearing portion 120 with an annular longitudinal cross-section. The annular pressure-bearing portion 120 has a uniform thickness in the circumferential direction, or the thickness of the pressure-bearing portion 120 facing the second shell 20 is greater than the thickness of the pressure-bearing portion 120 facing the first shell 10, or the central axis of the hollow cavity 121 does not coincide with the central axis of the pressure-bearing portion 120. For example, the central axis of the hollow cavity 121 is closer to the first shell 10 than the central axis of the pressure-bearing portion 120, thus creating an annular structure with uneven thickness in the pressure-bearing portion 120. Figure 5 As shown, preferably, the thickness b1 of the annular pressure-bearing portion 120 is 1-5 mm, for example, the thickness of the pressure-bearing portion 120 is 2 mm, 3 mm, etc.

[0061] like Figure 5 As shown, furthermore, the maximum inner diameter of the hollow cavity 121 is 1-5 mm. A larger inner diameter of the hollow cavity 121 can provide a greater deformation space for the pressure-bearing part 120, while a smaller inner diameter of the hollow cavity 121 can give the pressure-bearing part 120 a certain strength. Preferably, the maximum inner diameter of the hollow cavity 121 is 2 mm, 2.5 mm, 3 mm, etc.

[0062] In one embodiment, the bonding portion 110 includes a first adhesive layer 112, which is adhered to the edge of the first partition 30. The bonding portion 110 also includes a second adhesive layer 113, with the edge of the first partition 30 sandwiched between the first adhesive layer 112 and the second adhesive layer 113.

[0063] The first adhesive layer 112 is disposed on the side of the first partition 30 facing the first compartment 21, and the second adhesive layer 113 is disposed on the side of the first partition 30 facing the second compartment 22. The first adhesive layer 112, the first partition 30 and the second adhesive layer 113 are sequentially arranged in an overlapping structure. At least one of the following locations is provided with adhesive layers: the side of the first adhesive layer 112 facing the first partition 30, the side of the second adhesive layer 113 facing the first partition 30 and the pressure-bearing part 120. Preferably, adhesive layers are provided on the side of the first adhesive layer 112 facing the first partition 30, the side of the second adhesive layer 113 facing the first partition 30 and the pressure-bearing part 120, so that the sealing assembly 100 is disposed on the first partition 30 through the bonding part 110.

[0064] like Figure 5 As shown, preferably, the width a2 of the bonding portion 110 in the first direction is greater than 3 mm, that is, the width of the first adhesive layer 112 and the second adhesive layer 113 in the first direction is greater than 3 mm. For example, the longitudinal width of the bonding portion 110 is 5 mm, 8 mm, or 10 mm. The above-mentioned width of the bonding portion 110 ensures that the bonding portion 110 has sufficient area to be tightly connected with the first partition 30. The first adhesive layer 112 and the second adhesive layer 113 on both sides cover the first partition 30, forming a labyrinth structure to prevent gaps from forming between the sealing assembly 100 and the first partition 30, which could cause leakage.

[0065] In one embodiment, the thickness of the sealing assembly in the second direction is 0.1mm-10mm, where the second direction is perpendicular to the plane of the first partition. The thickness of the sealing assembly in the second direction is the thickness of the mating portion. Figure 5 As shown, preferably, the thickness a1 of the bonding portion 110 is 0.1-5 mm, for example, the thickness of the bonding portion 110 is 2 mm, 3 mm, etc.

[0066] In one embodiment, at least a portion of the outer surface of the sealing assembly 100 is arc-shaped. Specifically, at least a portion of the outer surface of the pressure-bearing portion 120 is arc-shaped. The arc-shaped design can evenly distribute external pressure, avoid stress concentration, and reduce the risk of excessive local deformation or damage. Under pressure, the arc-shaped surface can better adapt to external pressure, making deformation more uniform, thereby improving the reliability and durability of the seal. Under pressure, the arc-shaped surface can fit more tightly to the contact surface, fill irregular gaps, form a more effective seal, and better adapt to the shape of the contact surface, especially suitable for scenarios with uneven surfaces or minor deviations.

[0067] Preferably, the pressure-receiving portion 120 is cylindrical or elliptical in shape, and the generatrix of the cylindrical or elliptical pressure-receiving portion 120 is along the longitudinal direction of the sealing assembly 100. Optionally, at least a portion of the outer surface of the pressure-receiving portion 120 is arc-shaped. For example, the portion of the outer surface of the pressure-receiving portion 120 facing the second shell 20 is planar, and the portions on both sides of the pressure-receiving portion 120 facing the first chamber 21 or the second chamber 22 are arc-shaped, so that the longitudinal section of the pressure-receiving portion 120 is waist-shaped or arc-shaped, etc.

[0068] like Figure 5 As shown, preferably, the maximum outer diameter of the pressure-bearing part 120 is 3-15 mm. For example, the maximum outer diameter of the pressure-bearing part 120 is 5 mm, 6 mm, 7 mm, 8 mm, 10 mm, etc. The longitudinal and transverse dimensions of the pressure-bearing part 120 may not be equal. The transverse dimension is defined as the direction perpendicular to the longitudinal direction. For example, the transverse outer diameter is greater than the longitudinal outer diameter. When the longitudinal outer diameter is 7 mm, the transverse outer diameter can be 6 mm.

[0069] like Figure 4 , 5 As shown, in one embodiment, the sealing assembly 100 includes a straight section and a bent section. Specifically, along the longitudinal direction, the sealing assembly 100 includes a straight section and a bent section, the bent section being provided with a cutting seam 130.

[0070] For example, a cutting seam 130 is provided in the fitting portion 110. By providing the cutting seam 130 in the fitting portion 110, the sealing assembly 100 can better match the irregularly shaped first partition 30. The pressure-bearing portion 120 is not cut to ensure sealing. The fitting portion 110 with the cutting seam 130 makes the sealing assembly 100 more flexible. The fitting portions 110 on adjacent sides of the cutting seam 130 can be re-bonded to each other as a whole.

[0071] Specifically, the straight section corresponds to the straight portion of the first partition 30. The edge of the straight first partition 30 can be parallel to the surface of the first shell 10 or at a slight angle to the surface of the first shell 10. The bent section corresponds to the relief groove portion of the first partition 30. The relief groove of the first partition 30 is a groove or a protrusion structure. There can be multiple bends in the relief groove. Correspondingly, each bend matches a bent section and a cutting seam 130. For example, when the relief groove is a trapezoidal groove, there are four bends. When the sealing assembly 100 passes through, four cutting seams 130 are required to form four bent sections.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
