[0001] This application claims priority to Chinese patent application No. 2025203143481, filed on February 26, 2025, entitled "Battery Device and Electrical Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of battery technology, and in particular to a battery device and electrical equipment. Background Technology

[0003] When using a battery device, it needs to be installed on a vehicle or other electrical equipment. Therefore, a mounting structure needs to be installed on the battery device's housing to install or fix the housing to the corresponding electrical equipment.

[0004] However, the current mounting structure does not provide a good seal when connected to the housing, which can easily affect the overall sealing performance of the battery device. Summary of the Invention

[0005] Based on this, this application provides a battery device and an electrical appliance.

[0006] In a first aspect, this application provides a battery device, including a housing, a first sealing assembly, and at least two mounting members. Each mounting member is connected to the housing and is used to fix the housing to an external structure. The sealing member is disposed on at least one mounting member and has a connecting end and a protruding end. The connecting end is connected to the connecting surface of the corresponding mounting member, and the protruding end protrudes from the connecting surface of the corresponding mounting member and is sealed between at least two mounting members.

[0007] With the above structure, the first sealing component is integrated onto at least one mounting component, making the first sealing component and the corresponding mounting component form a whole, which can effectively reduce the number of parts in the assembly process and simplify the assembly process; in addition, the first sealing component forms a tongue-shaped sealing structure through the connecting end and the protruding end, which can effectively improve the sealing effect between the mounting component and the box.

[0008] In some embodiments, the first sealing component is configured as a resilient seal. Thus, when the seal is provided between mounts or between a mount and a housing, the resilient seal can interference-fill the gap between them, thereby further improving the sealing effect.

[0009] In some embodiments, each mounting component includes a first mounting sleeve, a second mounting sleeve, and a third mounting sleeve. The housing has an installation hole. The second mounting sleeve has a first end and a second end that are disposed opposite to each other. The second mounting sleeve passes through the installation hole, and both the first end and the second end extend out of the installation hole. The first mounting sleeve is connected to the first end, and the third mounting sleeve is connected to the second end.

[0010] Therefore, by setting the first mounting sleeve, the second mounting sleeve, and the third mounting sleeve, the connection and fixation between the sleeve and the housing can be achieved, and the housing can be more stably installed on the corresponding electrical equipment or other external structures, thus realizing the assembly of the battery device.

[0011] In some embodiments, the first sealing assembly includes a first sealing ring, a first mounting sleeve sleeved on the first end, a first sealing groove formed on the surface of the first mounting sleeve opposite to the first end, a second sealing groove formed on the surface of the first end opposite to the first mounting sleeve, a connecting end of the first sealing ring connected to the inner wall of the first sealing groove, and a protruding end of the first sealing ring engaged in the second sealing groove to seal the gap between the first mounting sleeve and the first end.

[0012] The above structure allows the first sealing ring to seal more stably between the second ends of the first mounting sleeve and the second mounting sleeve, improving the sealing effect between them.

[0013] In some embodiments, the first sealing assembly further includes a second sealing ring, a third mounting sleeve is sleeved on the second end, the first surface of the second end is disposed opposite to the third mounting sleeve, and a third sealing groove is formed on the first surface, a fourth sealing groove is formed on the surface of the third mounting sleeve opposite to the first surface, the connecting end of the second sealing ring is connected to the inner wall of the third sealing groove, and the protruding end of the second sealing ring is engaged in the fourth sealing groove to seal the gap between the first surface and the third mounting sleeve.

[0014] The above structure allows the second sealing ring to seal more stably between the third mounting sleeve and the second end of the second mounting sleeve, improving the sealing effect between the two.

[0015] In some embodiments, the battery device further includes a second sealing assembly that seals between the first mounting sleeve and the housing.

[0016] In some embodiments, the battery device further includes a second sealing assembly that seals between the second mounting sleeve and the third mounting sleeve.

[0017] By setting a second sealing component, a seal can be achieved between the first mounting sleeve and the housing, as well as between the second mounting sleeve and the third mounting sleeve, further improving the sealing effect.

[0018] In some embodiments, the second sealing assembly includes a third sealing ring, which surrounds the outer periphery of the first mounting sleeve and has a first sealing surface that is in contact with the surface of the housing.

[0019] The above structure increases the contact area between the third sealing ring and the surface of the housing, further improving the sealing effect of the third sealing ring on the gap between the first mounting sleeve and the housing.

[0020] In some embodiments, the second sealing assembly further includes a fourth sealing ring, the second end having a second surface perpendicular to the first surface, the fourth sealing ring being disposed on the second surface for sealing the gap between the second surface and the third mounting sleeve.

[0021] By adding a fourth sealing ring, the sealing effect between the second and third mounting sleeves can be further improved.

[0022] In some embodiments, the fourth sealing ring has a second sealing surface that is in contact with the surface of the third mounting sleeve.

[0023] The above structure increases the contact area between the fourth sealing ring and the inner wall of the third mounting sleeve, further improving the sealing effect of the fourth sealing ring on the gap between the second and third mounting sleeves.

[0024] In some embodiments, a third sealing assembly is also provided between the second mounting sleeve and the housing.

[0025] In some embodiments, a fourth sealing assembly is further provided between the second mounting sleeve and the third mounting sleeve.

[0026] The above structure can further improve the sealing effect between the second mounting sleeve and the housing, or between the second mounting sleeve and the third mounting sleeve, thus improving the overall sealing performance of the battery device.

[0027] In some embodiments, the third sealing assembly includes at least one fifth sealing ring, each fifth sealing ring being sealed between the second mounting sleeve and the water-cooled plate of the housing.

[0028] In some embodiments, the third sealing assembly includes at least one sixth sealing ring, each sixth sealing ring being sealed between the second mounting sleeve and the bottom protective plate of the housing. This further improves the sealing effect between the second mounting sleeve and the housing.

[0029] Secondly, this application also provides an electrical device, including the battery device described above.

[0030] In the aforementioned battery device and electrical equipment, each mounting component connects to the housing, enabling the housing to be fixed to external structures such as the electrical equipment. Simultaneously, the first sealing component is fixedly mounted on at least one mounting component, that is, the first sealing component is integrated onto at least one mounting component, making the first sealing component and the corresponding mounting component form an integral structure, which simplifies the mounting and sealing structure. Furthermore, the protruding end of the first sealing component can better engage between two structures that need to be sealed, such as between two mounting components, thereby effectively improving the sealing effect between them.

Detailed Implementation

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] Currently, judging from market trends, the application of power batteries is becoming increasingly widespread. Power batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also widely applied in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as other fields. With the continuous expansion of the application areas of power batteries, the market demand is also constantly increasing.

[0048] The structure of a battery device typically includes a housing and individual battery cells. The individual battery cells are placed inside the housing, which provides space for them and protects them effectively.

[0049] Specifically, the enclosure provides storage space for individual battery cells, protecting them. Furthermore, it allows for connection to external structures such as electrical equipment, enabling the installation of the battery pack within those devices.

[0050] Furthermore, the enclosure typically requires a mounting structure to connect to the electrical equipment. That is, the mounting structure is installed on the enclosure, allowing the battery pack to use the mounting structure as a load-bearing point to connect to the electrical equipment, thus achieving installation.

[0051] When the mounting structure connects to the casing, a gap is created between them, which needs to be sealed using a sealant. However, current sealing structures between the mounting structure and the casing are quite complex and have poor sealing performance, which can easily affect the overall sealing performance of the battery pack.

[0052] Based on the above considerations, in order to solve the problem of poor sealing between the mounting structure and the housing, one or more embodiments of this application provide a battery device. Each mounting component connects to the housing, enabling the housing to be fixed to an external structure such as an electrical device. Simultaneously, a first sealing component is fixedly disposed on at least one mounting component; that is, the first sealing component is integrated onto at least one mounting component, making the first sealing component and the corresponding mounting component form a single structure, thus simplifying the mounting and sealing structure. Furthermore, the protruding end of the first sealing component can better engage between the two structures requiring sealing, such as between two mounting components, thereby effectively improving the sealing effect between them.

[0053] It should be noted that the battery apparatus mentioned in the embodiments of this application may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells, which are connected in series, parallel, or mixed connections via a busbar.

[0054] In some embodiments, a battery cell assembly is typically formed by arranging multiple battery cells. As an example, a battery cell assembly can be a battery module, which is formed by arranging and fixing multiple battery cells together to form a single module. As an example, a battery module can be formed by bundling multiple battery cells together with cable ties.

[0055] In some embodiments, the battery device may be a battery pack, which includes a housing and one or more individual battery cells housed within the housing.

[0056] As an example, the battery cell assembly can be a battery module, which can be housed in a housing by fixing the battery module in the housing.

[0057] As an example, battery cell assemblies can also be housed in a housing by directly fixing multiple battery cells to the housing.

[0058] Referring to Figures 1 and 2, one embodiment of this application provides a battery device 100, including a housing 10, at least two mounting members 20, and a first sealing assembly 30. Each mounting member 20 is connected to the housing 10 and is used to fix the housing 10 to an external structure. The first sealing assembly 30 is disposed on at least one mounting member 20 and has a connecting end (not shown in the figures) and a protruding end (not shown in the figures). The connecting end is connected to the connecting surface of the corresponding mounting member 20, and the protruding end protrudes from the connecting surface of the corresponding mounting member 20 and seals between at least two mounting members 20.

[0059] It should be noted that the battery device 100 also includes individual battery cells, and the interior of the housing 10 is hollow, forming a cavity for accommodating the individual battery cells and other functional components. Thus, the individual battery cells and other functional components in the battery device 100 are housed within the cavity and protected by the housing 10, making the overall structure of the battery device 100 more stable.

[0060] Each mounting component 20 can be directly connected to the enclosure 10, or it can be connected to the enclosure 10 through the interconnection between the mounting components 20. After each mounting component 20 is connected to the enclosure 10, it can use itself as a force-bearing point to realize the installation and fixation of the enclosure 10 and external structures such as electrical equipment.

[0061] The first sealing component 30 refers to a structure capable of sealing the gaps between different mounting components 20. The first sealing component 30 is disposed on at least one mounting component 20, that is, the first sealing component 30 is integrated onto the corresponding mounting component 20, making the first sealing component 30 and the corresponding mounting component 20 a single integral structure. This reduces the number of parts in the assembly process and simplifies the assembly structure.

[0062] Specifically, the first sealing component 30 can be integrated onto the corresponding mounting component 20 by means of vulcanization or adhesive bonding, as long as a fixed connection between the first sealing component 30 and the corresponding mounting component 20 can be achieved, which will not be elaborated here.

[0063] The first sealing assembly 30 has a connecting end and a protruding end that are connected to each other. The surface on the mount 20 that is used to connect with the first sealing assembly 30 is the connecting surface. The connecting end is connected to the connecting surface of the corresponding mount 20 so that the first sealing assembly 30 can be smoothly integrated onto the corresponding mount 20.

[0064] Furthermore, the protruding end extends away from the connecting surface and protrudes from the connecting surface. Thus, the first sealing assembly 30 can be formed as a tongue-shaped sealing structure. When the first sealing assembly 30 is sealed between the two mounting members 20, the tongue-shaped sealing structure effectively improves the sealing effect.

[0065] With the above structure, the first sealing component 30 is integrated onto at least one mounting component 20, so that the first sealing component 30 and the corresponding mounting component 20 form a whole, which can effectively reduce the number of parts in the assembly process and simplify the assembly process; in addition, the first sealing component 30 forms a tongue-shaped sealing structure through the connecting end and the protruding end, which can effectively improve the sealing effect between the mounting component 20 and the housing 10.

[0066] In some embodiments, the first sealing component 30 is configured as a resilient seal. Specifically, the first sealing component 30 may, but is not limited to, be configured as a rubber seal.

[0067] With the above structure, when the seal is set between the mounting parts 20, the elastic seal can be filled into the gap between the two parts, thereby further improving the sealing effect.

[0068] In some embodiments, each mounting component 20 includes a first mounting sleeve 21, a second mounting sleeve 22, and a third mounting sleeve 23. The housing 10 has a mounting hole (not shown in the figure). The second mounting sleeve 22 has a first end 24 and a second end 25 that are disposed opposite to each other. The second mounting sleeve 22 passes through the mounting hole, and both the first end 24 and the second end 25 extend out of the mounting hole. The first mounting sleeve 21 is connected to the first end 24, and the third mounting sleeve 23 is connected to the second end 25.

[0069] It should be noted that the enclosure 10 typically includes a bottom protective plate and a frame, with the frame surrounding the outer perimeter of the bottom protective plate, together forming a receiving cavity. The enclosure 10 has mounting holes, which can be formed through the bottom protective plate, through the frame, or through both the bottom protective plate and the frame. The specific location of the mounting holes on the enclosure 10 can be adjusted according to the actual installation location of the mounting component 20, and will not be elaborated upon here.

[0070] Specifically, the first mounting sleeve 21 can be configured as a bottom sleeve, the second mounting sleeve 22 as a middle sleeve, and the third mounting sleeve 23 as an adapter sleeve. The middle sleeve passes through the mounting hole, and both the first end 24 and the second end 25 are located outside the mounting hole. Thus, the bottom sleeve can be connected to the first end 24 via screws, snap-fit ​​connections, or other connection methods, and the adapter sleeve can be connected to the second end 25 via screws, snap-fit ​​connections, or other connection methods, thereby achieving the connection and fixation between the bottom sleeve, the middle sleeve, the adapter sleeve, and the housing 10.

[0071] Furthermore, the bottom sleeve, middle sleeve, and transition sleeve can be connected to external structures such as electrical equipment through external connectors such as bolts, thereby enabling the enclosure 10 to be installed onto the electrical equipment.

[0072] Of course, the first mounting sleeve 21 can also be set as an adapter sleeve, and the third mounting sleeve 23 can be set as a bottom sleeve. In this case, the first mounting sleeve 21 is used to connect with the external structure.

[0073] Therefore, by setting the first mounting sleeve 21, the second mounting sleeve 22 and the third mounting sleeve 23, the connection and fixation between the sleeve and the housing 10 can be achieved, and the housing 10 can be more stably installed on the corresponding electrical equipment and other external structures, thus realizing the assembly of the battery device 100.

[0074] As shown in Figures 3, 4, and 5, in some embodiments, the first sealing assembly 30 includes a first sealing ring 31, a first mounting sleeve 21 sleeved on the first end 24, a first sealing groove 26 formed on the surface of the first mounting sleeve 21 opposite to the first end 24, a second sealing groove 27 formed on the surface of the first end 24 opposite to the first mounting sleeve 21, the connecting end of the first sealing ring 31 connected to the inner wall of the groove of the first sealing groove 26, and the protruding end of the first sealing ring 31 engaged in the second sealing groove 27 to seal the gap between the first mounting sleeve 21 and the first end 24.

[0075] Specifically, the first mounting sleeve 21 is fitted onto the outer periphery of the first end 24, that is, the inner wall of the first mounting sleeve 21 is opposite to the outer peripheral surface of the first end 24. A first sealing groove 26 is formed on the inner wall of the first mounting sleeve 21, and the outer edge of the first sealing ring 31 is formed as the connecting end of the first sealing ring 31. The first sealing ring 31 is fixedly installed in the first sealing groove 26 by wrapping around and engaging it.

[0076] Meanwhile, the inner edge of the first sealing ring 31 forms the protruding end of the first sealing ring 31, and a second sealing groove 27 is formed on the outer peripheral surface of the first end 24, with the second sealing groove 27 corresponding to the position of the first sealing groove 26. When the first mounting sleeve 21 is fitted onto the outer periphery of the first end 24, the protruding end of the first sealing ring 31 is engaged in the second sealing groove 27, thus more stably sealing the first sealing ring 31 between the first mounting sleeve 21 and the first end 24.

[0077] With the above structure, the first sealing ring 31 can be sealed more stably between the second end 25 of the first mounting sleeve 21 and the second mounting sleeve 22, thereby improving the sealing effect between the two.

[0078] Furthermore, the cross-section of the first sealing ring 31 may be, but is not limited to, rectangular. In this way, the first sealing ring 31 can be more stably engaged in the first sealing groove 26 and the second sealing groove 27, and can form a surface contact between the first sealing ring 31 and the first sealing groove 26 and the second sealing groove 27, thereby improving the sealing effect.

[0079] As shown in Figures 6, 7, and 8, in some embodiments, the first sealing assembly 30 further includes a second sealing ring 32, a third mounting sleeve 23 is sleeved on the second end 25, the first surface 251 of the second end 25 is opposite to the third mounting sleeve 23, and a third sealing groove 28 is formed on the first surface 251. A fourth sealing groove 29 is formed on the surface of the third mounting sleeve 23 opposite to the first surface 251. The connecting end of the second sealing ring 32 is connected to the inner wall of the groove of the third sealing groove 28, and the protruding end of the second sealing ring 32 is engaged in the fourth sealing groove 29 to seal the gap between the first surface 251 and the third mounting sleeve 23.

[0080] Specifically, the third mounting sleeve 23 is sleeved on the outer periphery of the second end 25 of the second mounting sleeve 22. The outer periphery of the second end 25 is opposite to the inner wall of the third mounting sleeve 23. That is, the outer periphery of the second end 25 is formed as a first surface 251, and a third sealing groove 28 is opened on the first surface 251.

[0081] The second sealing ring 32 is disposed around the outer periphery of the second end 25, and the inner edge of the second sealing ring 32 is formed as the connecting end of the second sealing ring 32 and is connected to the inner wall of the third sealing groove 28 to fix the second sealing ring 32 in the third sealing groove 28.

[0082] Meanwhile, the outer edge of the second sealing ring 32 forms the protruding end of the second sealing ring 32, and a fourth sealing groove 29 is formed on the inner wall of the third mounting sleeve 23, the fourth sealing groove 29 corresponding to the third sealing groove 28. When the third mounting sleeve 23 is fitted onto the outer periphery of the second end 25, the protruding end of the second sealing ring 32 is engaged in the fourth sealing groove 29, thus enabling the second sealing ring 32 to more stably seal between the third mounting sleeve 23 and the second end 25 of the second mounting sleeve 22.

[0083] The above structure allows the second sealing ring 32 to be more stably sealed between the third mounting sleeve 23 and the second end 25 of the second mounting sleeve 22, thereby improving the sealing effect between the two.

[0084] Furthermore, the cross-section of the second sealing ring 32 may be, but is not limited to, rectangular. In this way, the second sealing ring 32 can be more stably engaged in the third sealing groove 28 and the fourth sealing groove 29, and can form a surface contact between the second sealing ring 32 and the third sealing groove 28 and the fourth sealing groove 29, thereby improving the sealing effect.

[0085] In some embodiments, the battery device 100 further includes a second sealing assembly 40, which seals between the first mounting sleeve 21 and the housing 10. In some embodiments, the battery device 100 further includes a second sealing assembly 40, which seals between the second mounting sleeve 22 and the third mounting sleeve 23.

[0086] Specifically, the second sealing component 40 can be sealed between the first mounting sleeve 21 and the housing 10, or between the second mounting sleeve 22 and the third mounting sleeve 23, thereby further sealing the gap between the first mounting sleeve 21 and the housing 10, as well as the gap between the second mounting sleeve 22 and the third mounting sleeve 23.

[0087] Therefore, by setting the second sealing component 40, the sealing between the first mounting sleeve 21 and the housing 10 and between the second mounting sleeve 22 and the third mounting sleeve 23 can be achieved, further improving the sealing effect.

[0088] In some embodiments, the second sealing assembly 40 includes a third sealing ring 41, which surrounds the outer periphery of the first mounting sleeve 21 and has a first sealing surface 33 that is in contact with the surface of the housing 10.

[0089] Specifically, the surface of the third sealing ring 41 facing the bottom cover plate can be formed as the first sealing surface 33. In this way, the first sealing surface 33 and the surface of the bottom cover plate are in contact with each other, which can further improve the sealing effect.

[0090] As a specific embodiment, the cross-section of the third sealing ring 41 can be constructed as a right-angled triangle, with one right-angled side connected to the first mounting sleeve 21 and the other right-angled side forming the first sealing surface 33, which is in contact with the surface of the bottom protective plate, thereby achieving a seal between the first mounting sleeve 21 and the housing 10.

[0091] The above structure increases the contact area between the third sealing ring 41 and the surface of the housing 10, thereby further improving the sealing effect of the third sealing ring 41 on the gap between the first mounting sleeve 21 and the housing 10.

[0092] In some embodiments, the second sealing assembly 40 further includes a fourth sealing ring 42, the second end 25 having a second surface 252 perpendicular to the first surface 251, the fourth sealing ring 42 being disposed on the second surface 252 for sealing the gap between the second surface 252 and the third mounting sleeve 23.

[0093] Specifically, the second surface 252 is perpendicular to the first surface 251, that is, the second surface 252 is the end face of the second mounting sleeve 22. The fourth sealing ring 42 is disposed on the second surface 252 to integrate the fourth sealing ring 42 onto the second mounting sleeve 22.

[0094] When the third mounting sleeve 23 is fitted onto the outer periphery of the second end 25, the fourth sealing ring 42 can be disposed between the second surface 252 and the inner wall of the third mounting sleeve 23, thereby further sealing the gap between the second surface 252 and the third mounting sleeve 23.

[0095] By setting a fourth sealing ring 42, the sealing effect between the second mounting sleeve 22 and the third mounting sleeve 23 can be further improved.

[0096] In some embodiments, the fourth sealing ring 42 has a second sealing surface 34, which is in contact with the surface of the third mounting sleeve 23.

[0097] Specifically, the surface of the fourth sealing ring 42 facing the third mounting sleeve 23 is formed as the second sealing surface 34. In this way, the second sealing surface 34 and the third mounting sleeve 23 fit together and form a surface contact, which can further improve the sealing effect.

[0098] As a specific embodiment, the cross-section of the fourth sealing ring 42 can be constructed as a right-angled triangle, with one right-angled side connected to the second surface 252 and the other right-angled side forming the second sealing surface 34, which fits against the inner wall of the third mounting sleeve 23, thereby achieving a seal between the second mounting sleeve 22 and the third mounting sleeve 23.

[0099] The above structure increases the contact area between the fourth sealing ring 42 and the inner wall of the third mounting sleeve 23, further improving the sealing effect of the fourth sealing ring 42 on the gap between the second mounting sleeve 22 and the third mounting sleeve 23.

[0100] In some embodiments, a third sealing assembly 50 is further provided between the second mounting sleeve 22 and the housing 10. In some embodiments, a fourth sealing assembly 60 is further provided between the second mounting sleeve 22 and the third mounting sleeve 23.

[0101] Specifically, a third sealing component 50 can also be provided at the position where the second mounting sleeve 22 connects to the housing 10. The third sealing component 50 is sandwiched between the second mounting sleeve 22 and the housing 10, which can further improve the sealing effect between the second mounting sleeve 22 and the housing 10.

[0102] Furthermore, a fourth sealing component 60 can be provided at the connection position between the second mounting sleeve 22 and the third mounting sleeve 23. The fourth sealing component 60 may include multiple sealing rings, each of which can be sleeved on the outer periphery of the second mounting sleeve 22 and sandwiched between the second mounting sleeve 22 and the third mounting sleeve 23, which can further improve the sealing effect between the second mounting sleeve 22 and the third mounting sleeve 23.

[0103] Understandably, the sealing ring can be set as a rubber sealing ring to achieve an interference fit.

[0104] The above structure can further improve the sealing effect between the second mounting sleeve 22 and the housing 10 or between the second mounting sleeve 22 and the third mounting sleeve 23, making the overall sealing performance of the battery device 100 better.

[0105] In some embodiments, the third sealing assembly 50 includes at least one fifth sealing ring 51, each fifth sealing ring 51 being sealed between the second mounting sleeve 22 and the water-cooling plate of the housing 10. In some embodiments, the third sealing assembly 50 includes at least one sixth sealing ring 52, each sixth sealing ring 52 being sealed between the second mounting sleeve 22 and the bottom protective plate of the housing 10. This further improves the sealing effect between the second mounting sleeve 22 and the housing 10.

[0106] Based on the same concept as the battery device 100 described above, this application also provides an electrical device including the battery device 100 as described above.

[0107] According to one or more embodiments, when this application is used, the second mounting sleeve 22 is first installed through the mounting hole of the housing 10, and the first end 24 and the second end 25 of the second mounting sleeve 22 both extend out of the mounting hole.

[0108] Secondly, the first mounting sleeve 21 is fitted onto the first end 24, and at the same time, the protruding end of the first sealing ring 31 is engaged in the second sealing groove 27 to achieve a sealing fit between the inner wall of the first mounting sleeve 21 and the outer peripheral surface of the second mounting sleeve 22.

[0109] Furthermore, the third mounting sleeve 23 is fitted onto the second end 25. At this time, the protruding end of the second sealing ring 32 is engaged in the fourth sealing groove 29 to achieve a sealing fit between the outer circumferential surface of the second mounting sleeve 22 and the inner wall of the third mounting sleeve 23.

[0110] The third sealing ring 41 is disposed between the outer peripheral surface of the first mounting sleeve 21 and the surface of the bottom protective plate to achieve a sealing fit between the outer peripheral surface of the first mounting sleeve 21 and the surface of the bottom protective plate.

[0111] Furthermore, the fourth sealing ring 42 is sealed between the end face of the second mounting sleeve 22 and the inner wall of the third mounting sleeve 23, thereby achieving a sealing fit between the end face of the second mounting sleeve 22 and the inner wall of the third mounting sleeve 23.

[0112] Thus, the first sealing ring 31 and the third sealing ring 41 are integrated on the first mounting sleeve 21, and the second sealing ring 32 and the fourth sealing ring 42 are integrated on the second mounting sleeve 22. This effectively reduces the number of assembly parts and simplifies the assembly process. Furthermore, the protruding ends of each sealing ring form a tongue-shaped sealing structure, which further improves the sealing effect.

[0113] 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.

[0114] 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.
