Description

Technical Field

A receiving chamber is formed within the frame assembly, the base plate assembly is disposed at the bottom of the receiving chamber, and the cover plate assembly covers the top of the receiving chamber, thus forming a sealed cavity. The frame assembly includes a crossbeam that divides the receiving chamber into an electrical compartment and a battery cell compartment.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0046] The following is combined with Figures 1 to 11 This describes the frame assembly provided in the embodiments of the present invention.

[0047] Specifically, the frame assembly includes a partition beam 1, an electrical enclosure assembly 2, and a battery cell enclosure assembly 3.

[0048] The electrical enclosure assembly 2 and the partition beam 1 together form an electrical space 2011 for accommodating the control module 6. The control module 6 includes, but is not limited to, a high-voltage control box assembly and a battery management unit assembly.

[0049] The cell enclosure assembly 3 and the partition beam 1 together form a cell space 301 for accommodating the cells. Optionally, the cell enclosure assembly 3 is disposed on the side of the partition beam 1 opposite to the electrical enclosure assembly 2, that is, the cell space 301 and the electrical space 2011 are respectively disposed on both sides of the partition beam 1.

[0050] The partition beam 1 has a first flow channel 101 inside, which has a first inlet 102 and a first outlet 103. The first inlet 102 communicates with the cell space 301, and the first outlet 103 communicates with both the cell space 301 and the electrical space 2011. For example, the partition beam 1 can be configured as a profile with an internal cavity, and the cavity inside the partition beam 1 constitutes the first flow channel 101.

[0051] In this embodiment, the electrical enclosure assembly 2 and the partition beam 1 can form an electrical space 2011 to accommodate the control module 6, and the cell enclosure assembly 3 and the partition beam 1 can form a cell space 301 to accommodate the cells. When a cell in the cell space 301 experiences thermal runaway and generates high-temperature reactants, the high-temperature reactants can enter the first flow channel 101 through the first inlet 102. Guided and transported by the first flow channel 101, they are discharged from both the cell space 301 and the electrical space 2011 through the first outlet 103. This reduces the impact on other cells and avoids the problem of insulation failure of the control module 6 in the electrical space 2011 caused by the high-temperature reactants.

[0052] refer to Figure 3 , Figure 10 and Figure 11 As shown, in some embodiments provided by this utility model, the electrical enclosure assembly 2 includes a first end beam 202 and a first side beam 203.

[0053] The first end beam 202 is spaced apart from the partition beam 1, that is, the first end beam 202 is located on the side of the partition beam 1 away from the cell space 301, and there is a gap between the first end beam 202 and the partition beam 1.

[0054] The number of first side beams 203 is set to two. Both first side beams 203 are connected to the first end beam 202 and the partition beam 1. Optionally, the first side beams 203 and the first end beam 202 or the partition beam 1 can be connected by welding, injection molding, casting or by connecting parts. The two first side beams 203 are spaced apart, and the first side beams 203, the first end beam 202 and the partition beam 1 together form a receiving space 201. The electrical space 2011 is located inside the receiving space 201.

[0055] With this setup, the electrical enclosure component 2 has fewer parts and a simpler structure.

[0056] refer to Figure 3 or Figure 10As shown, optionally, in the length direction of the partition beam 1, the length of the first end beam 202 is less than the length of the partition beam 1. The first side beam 203 is set as an inclined beam, and along the direction from the cell space 301 to the electrical space 2011, the two first side beams 203 gradually approach each other and are respectively connected to the two ends of the first end beam 202. This arrangement allows the frame assembly to adapt to the corresponding chassis structure, ensuring that the frame assembly can be stably installed and effectively utilize the chassis space.

[0057] Of course, the partition beam 1 is not limited to an inclined setting; for example, refer to... Figure 11 As shown, in other embodiments provided by this utility model, the first side beam 203 includes a first beam segment 2034 and a second beam segment 2035, which are arranged at an angle, for example, they are arranged perpendicularly.

[0058] In this design, the first beam segment 2034 is connected to the partition beam 1, and the second beam segment 2035 is connected to the first end beam 202. For example, the first beam segment 2034 is perpendicular to the partition beam 1, and the second beam segment 2035 is collinear with the first end beam 202. This configuration allows the frame assembly to adapt to other types of chassis structures, ensuring stable installation and effective utilization of chassis space.

[0059] It should be noted that in practical applications, the first side beam 203 of the appropriate structure can be selected according to the construction of the vehicle chassis structure, and there is no limitation on this.

[0060] refer to Figure 6 As shown, in some embodiments provided by this utility model, at least one first side beam 203 is provided with a second flow channel 2031. The second flow channel 2031 is provided with a second outlet 2032, which is located on the side of the first side beam 203 away from the receiving space 201. The first outlet 103 of the first flow channel 101 is connected to the second flow channel 2031.

[0061] In this embodiment, after the battery cell generates high-temperature reactants, the high-temperature reactants enter the first flow channel 101 through the first inlet 102, enter the second flow channel 2031 through the first flow channel 101, and finally exit through the second outlet 2032 of the second flow channel 2031.

[0062] For reference, please refer to this setting. Figure 6 As shown, when the first flow channel 101 of the partition beam 1 is not convenient to be directly connected to the outside of the frame assembly, such as when the partition beam 1 is connected to the inner side of the first side beam 203, the first flow channel 101 of the partition beam 1 can be connected to the second flow channel 2031 of the first side beam 203, and the high-temperature reactants can be discharged through the second flow channel 2031. This satisfies both the connection requirements between the partition beam 1 and the first side beam 203 and the discharge requirements of the first flow channel 101.

[0063] Optionally, the first side beam 203 is configured as a profile with an internal cavity, and the cavity inside the first side beam 203 serves as the second flow channel 2031. Further, the partition beam 1 is abutted against the surface of the first side beam 203 near the receiving space 201, and the cavities between the partition beam 1 and the first side beam 203 are interconnected, so as to achieve the effect of connecting the first flow channel 101 and the second flow channel 2031.

[0064] Optionally, the first flow channel 101 of the partition beam 1 is connected to the second flow channels 2031 of the two first side beams 203. With this configuration, the high-temperature reactants in the first flow channel 101 can be discharged simultaneously through the second flow channels 2031 of the two first side beams 203, thereby increasing the discharge rate of the high-temperature reactants in the cell space 301 and reducing the impact of the high-temperature reactants on other cells.

[0065] refer to Figure 3 and Figure 11 As shown, in some embodiments provided by this utility model, the electrical enclosure assembly 2 further includes a partition beam 204.

[0066] The partition beam 204 is located in the accommodating space 201, and an exhaust space 2012 is formed between the partition beam 204 and the first side beam 203. An electrical space 2011 is formed on the side of the partition beam 204 away from the exhaust space 2012.

[0067] refer to Figure 6 As shown, the second flow channel 2031 is also provided with a second inlet 2033. The second inlet 2033 and the first outlet 103 are both connected to the exhaust space 2012. That is, the first flow channel 101 and the second flow channel 2031 are both connected to the exhaust space 2012, so that the first flow channel 101 and the second flow channel 2031 can be connected through the exhaust space 2012.

[0068] In this embodiment, after the battery cell generates high-temperature reactants, the high-temperature reactants enter the first flow channel 101 through the first inlet 102, then enter the exhaust space 2012 through the first flow channel 101, and then enter the second flow channel 2031 through the exhaust space 2012, finally being discharged through the second outlet 2032 of the second flow channel 2031. The partition beam 204 can prevent the high-temperature reactants in the exhaust space 2012 from entering the electrical space 2011.

[0069] refer to Figure 3As shown, the partition beam 1 and the first side beam 203 are directly connected, and the flow cross-sectional area between them is limited by the cross-sectional size of the partition beam 1. However, in this embodiment, the first outlet 103 of the first flow channel 101 and the second inlet 2033 of the second flow channel 2031 are connected through the exhaust space 2012. The size of the first outlet 103 and the second inlet 2033 is not affected by the cross-sectional size of the partition beam 1, so a larger size can be set, thereby increasing the flow speed of high-temperature reactants between the first flow channel 101 and the second flow channel 2031, and thus accelerating the discharge speed of high-temperature reactants in the cell space 301.

[0070] Optionally, refer to Figure 3 and Figure 11 As shown, there are two partition beams 204, spaced apart. Each partition beam 204 corresponds one-to-one with a first side beam 203, forming an exhaust space 2012 between each partition beam 204 and its corresponding first side beam 203. The first flow channel 101 of the partition beam 1 has two first outlets 103, each communicating with one of the two exhaust spaces 2012. An electrical space 2011 is formed between the two partition beams 204.

[0071] Optionally, refer to Figure 3 and Figure 11 As shown, the two ends of the partition beam 204 are connected to the partition beam 1 and the first side beam 203 respectively, and the partition beam 204, the first side beam 203 and the partition beam 1 together form an exhaust space 2012, and the partition beam 204, the first end beam 202 and the partition beam 1 together form an electrical space 2011.

[0072] Optionally, refer to Figure 3 and Figure 6 As shown, for the first side beam 203 configured as an inclined beam, the second outlet 2032 of its second flow channel 2031 is located on the outer surface of the first side beam 203.

[0073] Or, refer to Figure 11 As shown, for the first side beam 203 having a first beam segment 2034 and a second beam segment 2035, the second outlet 2032 of its second flow channel 2031 can be located on the outer surface of the first beam segment 2034 or the outer surface of the second beam segment 2035. Figure 11 The image shows an example of a second outlet 2032 located on the outer surface of the second beam segment 2035.

[0074] refer to Figure 3 , Figure 10 and Figure 11 As shown, in some embodiments provided by this utility model, the battery cell enclosure assembly 3 includes a second end beam 302 and a second side beam 303.

[0075] The second end beam 302 is spaced apart from the partition beam 1. That is, the second end beam 302 is located on the side of the partition beam 1 away from the first end beam 202, and there is a gap between the second end beam 302 and the partition beam 1.

[0076] There are two second side beams 303. Both second side beams 303 are connected to the second end beam 302 and the partition beam 1. The two second side beams 303 are spaced apart. The second side beams 303, the second end beam 302 and the partition beam 1 together form a battery cell space 301 for accommodating the battery cell.

[0077] With this setup, the number of parts in the cell enclosure assembly 3 is reduced, and the structure is simple.

[0078] Optionally, refer to Figure 3 and Figure 11 As shown, the second side beam 303 is connected to the first side beam 203. For example, one end of the first side beam 203 is connected to the first end beam 202, and the end of the first side beam 203 facing away from the first end beam 202 protrudes from the surface of the separator beam 1 facing the cell space 301 and is connected to the second side beam 303. That is, the second side beam 303 is connected to the separator beam 1 through the first side beam 203.

[0079] Optionally, the second side beam 303 and the first side beam 203 can be connected by welding, injection molding, casting or by means of connectors.

[0080] refer to Figure 3 , Figure 8 and Figure 9 As shown, in some embodiments provided by this utility model, the interior of the second side beam 303 is provided with a third flow channel 3031, the third flow channel 3031 is provided with a third inlet 3032 communicating with the cell space 301, and the third flow channel 3031 is connected to the fourth flow channel 3021 inside the second end beam 302 and / or the second flow channel 2031 inside the first side beam 203.

[0081] Among them, reference Figure 8 As shown, the fourth flow channel 3021 is provided with a fourth outlet 3022, which is located on the outside of the second end beam 302. For example, the fourth outlet 3022 is located on the surface of the second end beam 302 away from the cell space 301.

[0082] The second flow channel 2031 is provided with a second outlet 2032, which is located on the outside of the first side beam 203. For example, the second outlet 2032 is located on the surface of the first side beam 203 away from the receiving space 201.

[0083] In this embodiment, the high-temperature reactants in the cell space 301 can enter the third flow channel 3031 through the third inlet 3032. The high-temperature reactants in the third flow channel 3031 can then enter the fourth flow channel 3021 in the second end beam 302 and be discharged through the fourth outlet 3022 of the fourth flow channel 3021. Alternatively, the high-temperature reactants in the third flow channel 3031 can also enter the second flow channel 2031 in the first side beam 203 and be discharged through the second outlet 2032 of the second flow channel 2031.

[0084] This configuration allows for the rapid discharge of high-temperature reactants from the cell space 301. Furthermore, during cell arrangement, the cell's explosion-proof valve 10 can directly face the third inlet 3032 on the second side beam 303, enabling the high-temperature reactants generated by the cell to directly enter the third flow channel 3031. This shortens the flow path of the high-temperature reactants in the cell space 301, reducing their residence time and impact on other cells.

[0085] Optionally, the second end beam 302 is configured as a profile with an internal cavity, and the internal cavity of the second end beam 302 serves as the fourth flow channel 3021.

[0086] Optionally, the second side beam 303 is configured as a profile with an internal cavity, and the internal cavity of the second side beam 303 serves as the third flow channel 3031.

[0087] Optionally, refer to Figure 3 As shown, one end of the second side beam 303 is connected to the second end beam 302, and the cavity inside the second side beam 303 is connected to the cavity inside the second end beam 302, so as to achieve the effect of connecting the third flow channel 3031 and the fourth flow channel 3021.

[0088] Optionally, the end of the second side beam 303 that is away from the second end beam 302 is connected to the first side beam 203, and the cavity inside the second side beam 303 is connected to the cavity inside the first side beam 203, so as to achieve the effect of connecting the third flow channel 3031 with the second flow channel 2031.

[0089] Optionally, the second end beam 302 is provided with a fourth inlet 3023, which is connected to the cell space 301. This arrangement allows for the rapid discharge of high-temperature reactants from the cell space 301.

[0090] On the other hand, when the number of battery cells is at least two, the gap between two adjacent battery cell assemblies 5 can be opposite to the fourth inlet 3023 so that the reactants generated by the battery cells can pass through the gap between the battery cell assemblies 5 and enter the fourth inlet 3023, and finally be discharged through the fourth channel.

[0091] The above embodiments describe an example in which the partition beam 1 discharges high-temperature reactants through the first side beam 203. Of course, the high-temperature reactants in the partition beam 1 are not limited to being discharged through the first side beam 203.

[0092] For example, refer to Figure 10 As shown, in other embodiments provided by this utility model, the size of the electrical enclosure assembly 2 is smaller than the size of the partition beam 1 along its length, for example, referring to... Figure 10 As shown, the dimension of the partition beam 1 is a, and the dimension of the electrical enclosure assembly 2 is b, then a > b. The first exit 103 is located on the side of the partition beam 1 closer to the electrical enclosure assembly 2, and the position of the first exit 103 is offset from the position of the electrical enclosure assembly 2.

[0093] In this embodiment, the size of the electrical enclosure assembly 2 is smaller than the size of the partition beam 1, so that the frame assembly can be adapted to the corresponding chassis structure.

[0094] In addition, since the size of the electrical enclosure component 2 is smaller than that of the partition beam 1, the electrical enclosure component 2 will not completely block the partition beam 1. The first outlet 103 can be directly set on the side of the partition beam 1 close to the electrical enclosure component 2. The high-temperature reactants in the partition beam can be directly discharged from the first outlet 103 to the outside of the cell space 301 and the electrical space 2011, thereby shortening the discharge path of the high-temperature reactants and simplifying the overall structure of the frame assembly.

[0095] Furthermore, the third flow channel 3031 of the second side beam 303 can be connected to the first flow channel 101 of the partition beam 1 so that the high-temperature reactants in the second side beam 303 can be discharged through the partition beam 1.

[0096] refer to Figure 2 and Figure 5 As shown, the frame assembly also includes a sealing structure 4. A wire passage hole is provided on the partition beam 1, connecting the electrical space 2011 and the battery cell space 301, and is used for the cable 9 to pass through. The sealing structure 4 is used to seal the gap between the cable 9 and the wire passage hole.

[0097] In this embodiment, by sealing the gap between the cable 9 and the wire hole through the sealing structure 4, high-temperature reactants can be prevented from entering the electrical space 2011 through the gap between the cable 9 and the wire hole.

[0098] Optionally, the sealing structure 4 can be a sealing gasket or a sealing block. The sealing structure 4 seals the cable passage hole and has a through hole for the cable 9 to pass through. Furthermore, the sealing structure 4 can be bonded to the cable 9 or the partition beam 1 to improve the sealing effect.

[0099] Optionally, the wire passage hole intersects with the first flow channel 101 of the partition beam 1, and the sealing structure 4 is provided at the end of the wire passage hole near the electrical space 2011. In this way, the wire passage hole can both allow the cable 9 to pass through and serve as the first inlet 102 to allow the high-temperature reactants in the cell space 301 to enter the first flow channel 101, thereby reducing the number of openings on the partition beam 1 and reducing the processing difficulty of the partition beam 1.

[0100] In some embodiments of this invention, the frame assembly further includes an explosion-proof valve 10. The second outlet 2032 of the second flow channel 2031 and the fourth outlet 3022 of the fourth flow channel 3021 are both equipped with explosion-proof valves 10. By providing the explosion-proof valve 10, under normal circumstances, the explosion-proof valve 10 remains closed, allowing the battery pack to form a sealed space. When it is necessary to discharge high-temperature reactants, the explosion-proof valve 10 can open under the pressure of the high-temperature reactants, thereby discharging them.

[0101] It is understood that the technical means in the above embodiments can be combined with each other to obtain an overall improved solution. For example, a frame assembly includes a partition beam 1, an electrical enclosure assembly 2, and a battery cell enclosure assembly 3.

[0102] The electrical enclosure assembly 2 and the partition beam 1 together form an electrical space 2011 for accommodating the control module 6. The battery cell enclosure assembly 3 is located on the side of the partition beam 1 opposite to the electrical enclosure assembly 2, and together with the partition beam 1, forms a battery cell space 301 for accommodating the battery cells. The partition beam 1 has a first flow channel 101 inside, which has a first inlet 102 and a first outlet 103. The first inlet 102 communicates with the battery cell space 301, and the first outlet 103 communicates with both the battery cell space 301 and the electrical space 2011.

[0103] The electrical enclosure assembly 2 includes a first end beam 202, a first side beam 203, and a partition beam 204. The first end beam 202 is spaced apart from the partition beam 1. There are two first side beams 203. Both first side beams 203 connect the first end beam 202 and the partition beam 1, and are spaced apart. The first side beams 203, the first end beam 202, and the partition beam 1 together form a receiving space 201 for accommodating the control module 6.

[0104] The partition beam 204 is provided in the accommodating space 201, and the partition beam 204 and the first side beam 203 form an exhaust space 2012. The side of the partition beam 204 away from the exhaust space 2012 forms an electrical space 2011.

[0105] At least one first side beam 203 is provided with a second flow channel 2031. The second flow channel 2031 is provided with a second outlet 2032 and a second inlet 2033, with the second outlet 2032 located on the side of the first side beam 203 away from the receiving space 201. The second flow channel 2031 is also provided with a second inlet 2033, and both the second inlet 203 and the first outlet 103 of the first flow channel 101 are connected to the exhaust space 2012.

[0106] The cell enclosure assembly 3 includes a second end beam 302 and a second side beam 303. The second end beam 302 is spaced apart from the partition beam 1. There are two second side beams 303, each connecting the second end beam 302 and the partition beam 1, and the two second side beams 303 are spaced apart. The second side beams 303, the second end beam 302, and the partition beam 1 together form a cell space 301 for accommodating the cell.

[0107] The interior of the second side beam 303 is provided with a third flow channel 3031. The third flow channel 3031 is provided with a third inlet 3032 that communicates with the cell space 301. The two ends of the second side beam 303 are respectively connected to the first side beam 203 and the second end beam 302. The third flow channel 3031 is connected to the fourth flow channel 3021 inside the second end beam 302 and the second flow channel 2031 of the first side beam 203.

[0108] Among them, reference Figure 8 As shown, the fourth flow channel 3021 is provided with a fourth outlet 3022, which is located outside the second end beam 302. The fourth flow channel 3021 is also provided with a fourth inlet 3023, which is connected to the cell space 301.

[0109] refer to Figure 3 As shown, at least two sets of battery cell assemblies 5 are arranged within the battery cell space 301, with at least two battery cell assemblies 5 distributed along the length of the partition beam 1. The battery cells in the battery cell assembly 5 adjacent to the second side beam 303 have their explosion-proof valves facing the third inlet 3032 of the second side beam 303. The gap between two adjacent battery cell assemblies 5 has one end opposite to the first inlet 102 on the partition beam 1, and the other end opposite to the fourth inlet 3023 on the second end beam 302.

[0110] For example, Figure 3 The arrows marked in the diagram indicate the direction of the high-temperature reactants. The high-temperature reactants generated by the battery cell opposite to the second side beam 303 can be discharged into the third flow channel 3031 within the second side beam 303, and then discharged into the second flow channel 2031 of the first side beam 203 or the fourth flow channel 3021 of the second end beam 302.

[0111] More specifically, the high-temperature reactants emitted by the cells near the partition beam 1 are discharged through the third flow channel 3031 and the second flow channel 2031, while the high-temperature reactants emitted by the cells near the second end beam 302 are discharged through the third flow channel 3031 and the fourth flow channel 3021, in order to shorten the emission path of the high-temperature reactants.

[0112] In the case where the battery cell discharges high-temperature reactants into the gap between the two battery cell assemblies 5, the high-temperature reactants in the gap can either enter the first flow channel 101 of the partition beam 1 and then be discharged from the first flow channel 101 through the exhaust space 2012 and the second flow channel 2031 of the first side beam 203, or enter the fourth flow channel 3021 of the second end beam 302 through the fourth inlet 3023 and be discharged through the fourth outlet 3022 of the fourth flow channel 3021.

[0113] With this configuration, high-temperature reactants generated by cells near the second side beam 303 can be discharged via the second side beam 303 and then via the first side beam 203 or the second end beam 302. High-temperature reactants within the gaps between the cell assemblies 5 can be discharged via the partition beam 1 and the first side beam 203 or via the second end beam 302. This ensures that all locations within the cell space 301 where high-temperature reactants may be generated have corresponding discharge paths, thereby reducing the residual time of high-temperature reactants within the cell space 301 and shortening the discharge path of high-temperature reactants.

[0114] This utility model embodiment also provides a housing assembly.

[0115] Specifically, the housing assembly includes a base plate assembly 7, a cover plate assembly 8, and the frame assembly described above.

[0116] The base plate assembly 7 supports the bottom of the frame assembly, and the cover plate assembly 8 covers the top of the frame assembly. Specifically, the top of the cell space 301 is sealed by the cover plate assembly 8, and the bottom of the cell space 301 is sealed by the base plate assembly 7, so that the cell space 301 forms a sealed chamber. Similarly, the top of the electrical space 2011 is sealed by the cover plate assembly 8, and the bottom of the electrical space 2011 is sealed by the base plate assembly 7, so that the electrical space 2011 forms a sealed chamber.

[0117] It should be noted that the housing assembly includes the frame assembly, and therefore includes all the advantages of the frame assembly mentioned above, so it will not be elaborated further.

[0118] Optionally, the cover assembly 8 includes a first cover 801 and a second cover 802. The first cover 801 covers the top of the cell space 301 and is connected to the cell enclosure assembly 3. The second cover 802 covers the top of the electrical space 2011 and is connected to the electrical enclosure assembly 2.

[0119] In this embodiment, the cover plate assembly 8 is designed as a split structure. On the one hand, this reduces the size of the cover plate assembly 8, thereby reducing the difficulty of its production, transportation, and hoisting. On the other hand, during the repair or maintenance of the battery cell or control module 6, only the first cover plate 801 or the second cover plate 802 needs to be opened, without disassembling the entire cover plate assembly 8, thus reducing the difficulty of repair or maintenance.

[0120] Optionally, the base plate assembly 7 includes a cooling plate 701 and a bottom protective plate 702. The cooling plate 701 is located at the bottom of the frame assembly and connects to the electrical enclosure assembly 2 and the cell enclosure assembly 3. The cooling plate 701 can cool the cells and control module 6. The bottom protective plate 702 is located on the side of the cooling plate 701 facing away from the frame assembly and provides protection for the battery pack.

[0121] This utility model also provides a battery pack in this embodiment.

[0122] Specifically, the battery pack includes the frame assembly or the housing assembly as described above, the cell space 301 contains the cell assembly 5, and the electrical space 2011 contains the control module 6.

[0123] The number of battery cell assemblies 5 is set to at least two, and at least two battery cell assemblies 5 are arranged along the length direction of the separator beam 1, which is the length direction of the separator beam 1. Figure 10 The first inlet 102 is positioned relative to the gap between the first inlet 102 and the two adjacent cell assemblies 5 in the direction of a.

[0124] It should be noted that the battery pack includes the frame assembly or the housing assembly, and thus has the corresponding technical effects, which will not be elaborated further.

[0125] Optionally, one end of the gap between any two adjacent cell assemblies 5 corresponds to a first inlet 102, and the other end corresponds to a fourth inlet 3023. This arrangement can increase the emission rate of high-temperature reactants within the gap and shorten the emission path of high-temperature reactants.

[0126] This utility model also provides a vehicle.

[0127] Specifically, the vehicle includes the frame assembly, the housing assembly, or the battery pack described above.

[0128] It should be noted that the vehicle includes the frame assembly, shell assembly, or battery pack, and thus also includes the corresponding technical effects, so these will not be elaborated further.

[0129] Optionally, the frame assembly is mounted on the vehicle, with one of the first end beam 202 and the second end beam 302 facing the front of the vehicle and the other facing the rear. Two first side beams 203 are located near the left and right sides of the vehicle, respectively, and two second side beams 303 are also located near the left and right sides of the vehicle, respectively. Because the first side beams 203 and the second end beams 302 are equipped with outlets for discharging high-temperature reactants, and are positioned near the front and rear of the vehicle, they are kept away from the path taken by passengers when disembarking, thus preventing contact between the high-temperature reactants and the passengers.

[0130] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
