[0039] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

If present, 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 implementation method.

[0042] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0043] The structure of a battery device generally includes a box and a battery cell. The battery cell is placed in the box, so that the box provides a storage space for the battery cell and provides good protection for the battery cell.

[0044] Specifically, the box body can provide a storage space for the battery cells and protect the battery cells. On the other hand, the box body can also be used to connect with external structures such as electrical equipment to achieve installation of the battery device on the electrical equipment.

[0045] Furthermore, the box body usually needs to be connected to the electrical equipment by means of a mounting structure, that is, the mounting structure is arranged on the box body, so that the battery device can be connected to the electrical equipment by using the mounting structure on the box body as a force point, thereby achieving installation.

[0046] When the mounting structure is connected to the box, a gap is generated between the two, so a seal is required to seal the gap between the two. However, the current sealing structure between the mounting structure and the box is relatively complex, and the sealing effect is poor, which easily affects the overall sealing performance of the battery device.

[0047] Based on the above considerations, in order to solve the problem of poor sealing effect between the previous mounting structure and the box body, a battery device is provided in one or more embodiments of the present application, and each mounting part is connected to the box body, so that the box body can be fixed to an external structure such as an electrical device. At the same time, the first sealing component is fixedly arranged on at least one mounting part, that is, the first sealing component is integrated on at least one mounting part, so that the first sealing component and the corresponding mounting part form an integral structure, which can simplify the mounting sealing structure. In addition, the protruding end of the first sealing component can be better clamped between the two structures that need to be sealed, such as clamped between two mounting parts, so that the sealing effect between the two can be effectively improved.

[0048] It should be noted that the battery apparatus mentioned in the embodiments of the present application may include one or more battery cell assemblies for providing voltage and capacity. The battery cell assembly may include multiple battery cells, which are connected in series, in parallel or in mixed connection through a busbar.

[0049] In some embodiments, a battery cell assembly is generally formed by arranging a plurality of battery cells. As an example, a battery cell assembly may be a battery module, which is formed by arranging and fixing a plurality of battery cells to form an independent module. As an example, a battery module may be formed by bundling a plurality of battery cells by a cable tie.

[0050] In some embodiments, the battery device may be a battery pack, which includes a case and one or more battery cell assemblies, wherein the battery cell assemblies are accommodated in the case.

[0051] As an example, the battery cell assembly may be a battery module, and the battery cell assembly may be accommodated in the box by fixing the battery module in the box.

[0052] As an example, the battery cell assembly may also be housed in the case by directly fixing a plurality of battery cells to the case.

[0053] See also Figure 1 and Figure 2An embodiment of the present application provides a battery device 100, including a box body 10, at least two mounting members 20, and a first sealing assembly 30. Each mounting member 20 is connected to the box body 10 and is used to fix the box body 10 to an external structure. The first sealing assembly 30 is arranged on at least one mounting member 20, and has a connecting end (not shown in the figure) and a protruding end (not shown in the figure), the connecting end is connected to the connecting surface of the corresponding mounting member 20, the protruding end protrudes from the connecting surface of the corresponding mounting member 20, and the protruding end is sealed between at least two mounting members 20.

[0054] It should be noted that the battery device 100 also includes a battery cell, and the interior of the box 10 is hollow, forming a receiving cavity for receiving the battery cell and other functional components. In this way, the battery cell and other functional components in the battery device 100 are arranged in the receiving cavity, and can be protected by the box 10, so that the overall structure of the battery device 100 is more stable.

[0055] Each mounting part 20 can be directly connected to the box body 10, or it can be connected to the box body 10 by mutual connection between the mounting parts 20. After each mounting part 20 is connected to the box body 10, it can use itself as a force point to achieve the installation and fixation of the box body 10 and external structures such as electrical equipment.

[0056] The first sealing assembly 30 is a structure that can seal the gaps between different mounting parts 20. The first sealing assembly 30 is disposed on at least one mounting part 20, that is, the first sealing assembly 30 is integrated with the corresponding mounting part 20, so that the first sealing assembly 30 and the corresponding mounting part 20 form an integral structure. In this way, the number of parts in the assembly process can be reduced and the assembly structure can be simplified.

[0057] Specifically, the first sealing component 30 can be integrated on the corresponding mounting component 20 through, but not limited to, a vulcanization process or gluing, etc., 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.

[0058] The first sealing component 30 has a connecting end and a protruding end that are connected to each other, wherein the surface on the mounting component 20 used to connect with the first sealing component 30 is the connecting surface, and the connecting end is connected to the connecting surface of the corresponding mounting component 20 so that the first sealing component 30 can be smoothly integrated on the corresponding mounting component 20.

[0059] Furthermore, the protruding end is extended in a direction away from the connection surface and protrudes from the connection surface. In this way, the first sealing component 30 can be formed into a tongue-shaped sealing structure. When the first sealing component 30 is sealed between the two mounting parts 20, the tongue-shaped sealing structure can effectively improve the sealing effect.

[0060] Through the above structure, the first sealing component 30 is integrated into 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 box body 10.

[0061] In some embodiments, the first sealing component 30 is configured as an elastic sealing member. Specifically, the first sealing component 30 can be configured as a rubber sealing member but is not limited thereto.

[0062] Through the above structure, when the seal is set between the mounting parts 20, the elastic seal can be interference filled in the gap between the two, so as to further improve the sealing effect.

[0063] In some embodiments, each mounting component 20 includes a first mounting sleeve 21, a second mounting sleeve 22 and a third mounting sleeve 23. A mounting hole (not shown in the figure) is opened on the box body 10. The second mounting sleeve 22 has a first end 24 and a second end 25 that are relatively arranged. The second mounting sleeve 22 is inserted into the mounting hole, and the first end 24 and the second end 25 both 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.

[0064] It should be noted that the box 10 generally includes a bottom guard plate and a frame, and the frame is arranged around the outer periphery of the bottom guard plate, and the two together enclose a receiving cavity. The box 10 is provided with a mounting hole, wherein the mounting hole can be opened through the bottom guard plate, can also be opened through the frame, and can also be opened through the bottom guard plate and the frame at the same time. The specific opening position of the mounting hole on the box 10 can be adjusted according to the actual installation position of the mounting part 20, which will not be elaborated here.

[0065] Specifically, the first mounting sleeve 21 can be set as a bottom sleeve, the second mounting sleeve 22 can be set as a middle sleeve, and the third mounting sleeve 23 can be set as a transfer sleeve. The middle sleeve is inserted into the mounting hole, and the first end 24 and the second end 25 are both located outside the mounting hole. In this way, the bottom sleeve can be connected to the first end 24 by screwing, clamping or other connection methods, and the transfer sleeve can be connected to the second end 25 by screwing, clamping or other connection methods, so as to realize the connection and fixation between the bottom sleeve, the middle sleeve, the transfer sleeve and the box body 10.

[0066] Furthermore, the bottom sleeve, the middle sleeve, and the adapter sleeve can be connected to external structures such as electrical equipment through external connectors such as bolts, so that the box body 10 can be installed on the electrical equipment.

[0067] Of course, the first mounting sleeve 21 can also be set as a transfer sleeve, and the third mounting sleeve 23 is set as a bottom sleeve. In this case, the first mounting sleeve 21 is used to connect with an external structure.

[0068] Therefore, by providing the first mounting sleeve 21 , the second mounting sleeve 22 and the third mounting sleeve 23 , the connection and fixation with the box body 10 can be achieved, and the box body 10 can be more stably installed on the corresponding external structure such as the electrical equipment, thereby realizing the assembly of the battery device 100 .

[0069] like Figure 3 , Figure 4 as well as Figure 5 As shown, in some embodiments, the first sealing assembly 30 includes a first sealing ring 31, the first mounting sleeve 21 is sleeved on the first end 24, a first sealing groove 26 is opened on the surface of the first mounting sleeve 21 opposite to the first end 24, a second sealing groove 27 is opened on the surface of the first end 24 opposite to the first mounting sleeve 21, the connecting end of the first sealing ring 31 is connected to the inner wall of the first sealing groove 26, and the protruding end of the first sealing ring 31 is clamped in the second sealing groove 27 to seal the gap between the first mounting sleeve 21 and the first end 24.

[0070] Specifically, the first mounting sleeve 21 is sleeved on the outer periphery of the first end 24, that is, the inner wall of the first mounting sleeve 21 is arranged opposite to the outer periphery of the first end 24. A first sealing groove 26 is provided on the inner wall of the first mounting sleeve 21, and the outer edge of the first sealing ring 31 forms the connecting end of the first sealing ring 31. The first sealing ring 31 is clamped around and connected in the first sealing groove 26, so that the first sealing ring 31 can be fixed in the first sealing groove 26.

[0071] At the same time, the inner edge of the first sealing ring 31 forms a protruding end of the first sealing ring 31, and a second sealing groove 27 is provided on the outer circumference of the first end 24, and the positions of the second sealing groove 27 and the first sealing groove 26 correspond to each other. When the first mounting sleeve 21 is sleeved on the outer circumference of the first end 24, the protruding end of the first sealing ring 31 is clamped in the second sealing groove 27, so that the first sealing ring 31 is more stably sealed between the first mounting sleeve 21 and the first end 24.

[0072] Through the above structure, the first sealing ring 31 can be more stably sealed between the first mounting sleeve 21 and the second end 25 of the second mounting sleeve 22, thereby improving the sealing effect therebetween.

[0073] In addition, the cross-section of the first sealing ring 31 can be but is not limited to being set to a rectangle, so that 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 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.

[0074] like Figure 6 , Figure 7 as well as Figure 8 As shown, in some embodiments, the first sealing assembly 30 also includes a second sealing ring 32, the third mounting sleeve 23 is sleeved on the second end 25, the first surface 251 of the second end 25 is arranged opposite to the third mounting sleeve 23, and a third sealing groove 28 is opened on the first surface 251, and a fourth sealing groove 29 is opened 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 third sealing groove 28, and the protruding end of the second sealing ring 32 is clamped in the fourth sealing groove 29 to seal the gap between the first surface 251 and the third mounting sleeve 23.

[0075] Specifically, the third mounting sleeve 23 is sleeved on the outer periphery of the second end 25 of the second mounting sleeve 22, and the outer peripheral surface of the second end 25 is arranged opposite to the inner wall of the third mounting sleeve 23, that is, the outer peripheral surface 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.

[0076] The second sealing ring 32 is arranged around the outer circumference of the second end 25 , and the inner edge of the second sealing ring 32 forms a 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 .

[0077] At the same time, the outer edge of the second sealing ring 32 is formed as the protruding end of the second sealing ring 32, and a fourth sealing groove 29 is opened on the inner wall of the third mounting sleeve 23, and the fourth sealing groove 29 corresponds to the position of the third sealing groove 28. When the third mounting sleeve 23 is sleeved on the outer periphery of the second end 25, the protruding end of the second sealing ring 32 is clamped in the fourth sealing groove 29, so that the second sealing ring 32 can be more stably sealed between the third mounting sleeve 23 and the second end 25 of the second mounting sleeve 22.

[0078] Through the above structure, the second sealing ring 32 can 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 therebetween.

[0079] In addition, the cross-section of the second sealing ring 32 can be but is not limited to being set to a rectangle, so that 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 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.

[0080] In some embodiments, the battery device 100 further includes a second sealing assembly 40 , which is sealed between the first mounting sleeve 21 and the box body 10 and / or between the second mounting sleeve 22 and the third mounting sleeve 23 .

[0081] Specifically, the second sealing assembly 40 can be sealed between the first mounting sleeve 21 and the box body 10, or can be sealed between the second mounting sleeve 22 and the third mounting sleeve 23, so as to further seal the gap between the first mounting sleeve 21 and the box body 10, and the gap between the second mounting sleeve 22 and the third mounting sleeve 23.

[0082] Therefore, by providing the second sealing assembly 40 , it is possible to achieve sealing between the first mounting sleeve 21 and the box body 10 and between the second mounting sleeve 22 and the third mounting sleeve 23 , further improving the sealing effect.

[0083] In some embodiments, the second sealing assembly 40 includes a third sealing ring 41 , which is disposed around the outer circumference of the first mounting sleeve 21 , and has a first sealing surface 33 , which fits the surface of the box 10 .

[0084] Specifically, the surface of the third sealing ring 41 facing the bottom guard plate can be formed as the first sealing surface 33. In this way, the first sealing surface 33 and the surface of the bottom guard plate fit each other, and there is surface contact between the two, which can further improve the sealing effect.

[0085] As a specific embodiment, the cross-section of the third sealing ring 41 can be constructed as a right-angled triangle, one of the right-angled sides is connected to the first mounting sleeve 21, and the other right-angled side forms a first sealing surface 33 and fits with the surface of the bottom guard plate, thereby achieving sealing between the first mounting sleeve 21 and the box body 10.

[0086] Through the above structure, the contact area between the third sealing ring 41 and the surface of the box body 10 can be increased, and the sealing effect of the third sealing ring 41 on the gap between the first mounting sleeve 21 and the box body 10 can be further improved.

[0087] In some embodiments, the second sealing assembly 40 further includes a fourth sealing ring 42 . The second end 25 has a second surface 252 perpendicular to the first surface 251 . The fourth sealing ring 42 is disposed on the second surface 252 to seal the gap between the second surface 252 and the third mounting sleeve 23 .

[0088] Specifically, the second surface 252 is perpendicular to the first surface 251 , that is, the second surface 252 is an end surface of the second mounting sleeve 22 . The fourth sealing ring 42 is disposed on the second surface 252 , so as to integrate the fourth sealing ring 42 on the second mounting sleeve 22 .

[0089] When the third mounting sleeve 23 is sleeved on the outer circumference 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 .

[0090] By providing the fourth sealing ring 42 , the sealing effect between the second mounting sleeve 22 and the third mounting sleeve 23 can be further improved.

[0091] In some embodiments, the fourth sealing ring 42 has a second sealing surface 34 , and the second sealing surface 34 is in contact with the surface of the third mounting sleeve 23 .

[0092] Specifically, a surface of the fourth sealing ring 42 facing the third mounting sleeve 23 is formed as a second sealing surface 34 , so that the second sealing surface 34 and the third mounting sleeve 23 fit each other to form surface contact, which can further improve the sealing effect.

[0093] As a specific embodiment, the cross-section of the fourth sealing ring 42 can be constructed as a right-angled triangle, one of the right-angled sides is connected to the second surface 252, and the other right-angled side forms the second sealing surface 34, and fits with the inner wall of the third mounting sleeve 23, thereby achieving sealing between the second mounting sleeve 22 and the third mounting sleeve 23.

[0094] Through the above structure, the contact area between the fourth sealing ring 42 and the inner wall of the third mounting sleeve 23 can be increased, and the sealing effect of the fourth sealing ring 42 on the gap between the second mounting sleeve 22 and the third mounting sleeve 23 can be further improved.

[0095] In some embodiments, a third sealing assembly 50 is further disposed between the second mounting sleeve 22 and the housing 10 , and / or a fourth sealing assembly 60 is further disposed between the second mounting sleeve 22 and the third mounting sleeve 23 .

[0096] Specifically, a third sealing assembly 50 may be further provided at the position where the second mounting sleeve 22 is connected to the housing 10 . The third sealing assembly 50 is sandwiched between the second mounting sleeve 22 and the housing 10 , and can further improve the sealing effect between the second mounting sleeve 22 and the housing 10 .

[0097] Furthermore, a fourth sealing assembly 60 can be provided at the connection position between the second mounting sleeve 22 and the third mounting sleeve 23. The fourth sealing assembly 60 can include a plurality of sealing rings. Each sealing ring can be sleeved on the outer periphery of the second mounting sleeve 22 and clamped between the second mounting sleeve 22 and the third mounting sleeve 23, thereby further improving the sealing effect between the second mounting sleeve 22 and the third mounting sleeve 23.

[0098] It can be understood that the sealing ring can be configured as a rubber sealing ring to achieve an interference fit.

[0099] Through the above structure, the sealing effect between the second mounting sleeve 22 and the box body 10 or between the second mounting sleeve 22 and the third mounting sleeve 23 can be further improved, so that the sealing performance of the overall structure of the battery device 100 is better.

[0100] In some embodiments, the third sealing assembly 50 includes at least one fifth sealing ring 51, each of which is sealingly disposed between the second mounting sleeve 22 and the water-cooling plate of the box body 10. And / or, the third sealing assembly 50 includes at least one sixth sealing ring 52, each of which is sealingly disposed between the second mounting sleeve 22 and the bottom guard plate of the box body 10. Thus, the sealing effect between the second mounting sleeve 22 and the box body 10 can be further improved.

[0101] Based on the same concept as the above-mentioned battery device 100 , the present application also provides an electrical device, including the above-mentioned battery device 100 .

[0102] According to one or more embodiments, when the present application is used, the second mounting sleeve 22 is firstly inserted into the mounting hole of the box body 10, and the first end 24 and the second end 25 of the second mounting sleeve 22 are both extended out of the mounting hole.

[0103] Secondly, the first mounting sleeve 21 is sleeved on the first end 24 , and at the same time, the protruding end of the first sealing ring 31 is clamped in the second sealing groove 27 to achieve sealing cooperation between the inner wall of the first mounting sleeve 21 and the outer peripheral surface of the second mounting sleeve 22 .

[0104] Furthermore, the third mounting sleeve 23 is sleeved on the second end 25 , and at this time, the protruding end of the second sealing ring 32 is clamped in the fourth sealing groove 29 to achieve sealing cooperation between the outer peripheral surface of the second mounting sleeve 22 and the inner wall of the third mounting sleeve 23 .

[0105] The third sealing ring 41 is sealingly disposed between the outer circumferential surface of the first mounting sleeve 21 and the surface of the bottom guard plate to achieve sealing cooperation between the outer circumferential surface of the first mounting sleeve 21 and the surface of the bottom guard plate.

[0106] Furthermore, the fourth sealing ring 42 is sealingly disposed between the end surface of the second mounting sleeve 22 and the inner wall of the third mounting sleeve 23 , thereby enabling sealing cooperation between the end surface of the second mounting sleeve 22 and the inner wall of the third mounting sleeve 23 .

[0107] In this way, 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, which can effectively reduce the number of assembly parts during the assembly process, simplify the assembly process and difficulty. In addition, the protruding end of each sealing ring forms a tongue-shaped sealing structure, which can further improve the sealing effect.

[0108] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0109] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
