Technical Field

[0002] The present disclosure relates to the field of automobile technology, and in particular to a battery mounting structure and a vehicle. Background Art

[0003] Electric vehicles are one of the development directions of new energy vehicles, which mainly use power batteries as the power source to drive the vehicle. Summary of the Invention

[0004] The present disclosure provides a battery installation structure and a vehicle, which are used to improve the battery integration method of new energy vehicles and increase the space utilization rate of the lower body of the vehicle.

[0005] In a first aspect, a battery mounting structure is provided, which includes a mounting assembly, a battery cell assembly, and two door sill beams.

[0006] The mounting assembly defines a mounting cavity with openings at both ends, and the battery cell assembly is disposed within the mounting cavity. Two threshold beams are disposed opposite each other and connected to the mounting assembly. Each threshold beam corresponds to an opening, and the threshold beam covers the corresponding opening.

[0007] According to some embodiments of the present disclosure, the battery mounting structure can replace part of the battery pack frame in related art with two sill beams. This allows the space for accommodating the battery cell assembly to expand toward the sill beam, increasing the space for arranging the battery cell assembly and improving the space utilization of the lower vehicle body. This allows the vehicle to accommodate more battery cells, increasing the vehicle's battery capacity and thus its range.

[0008] In some embodiments, the mounting assembly includes a cover and a bottom guard plate. The bottom guard plate is located on the underside of the cover and is removably connected to the cover. The bottom guard plate and the cover define a mounting cavity. At least one of the cover or the bottom guard plate is connected to the two door sill beams.

[0009] According to the above technical means, some embodiments of the present disclosure can separate the cover and the bottom guard plate to facilitate the repair or replacement of the battery cell assembly.

[0010] In some embodiments, the cover body includes a cover plate assembly and two support beams. The cover plate assembly is disposed opposite the bottom guard plate. The two support beams are located between the cover plate assembly and the bottom guard plate and are connected to the cover plate assembly. The two support beams are located between the two door sill beams, with each support beam contacting the two door sill beams at its ends. The two support beams are disposed opposite each other and contact the bottom guard plate, such that the bottom guard plate, the cover plate assembly, and the two support beams enclose a mounting cavity.

[0011] According to the above technical means, some embodiments of the present disclosure can support the rocker beam with two support beams to prevent the two rocker beams from deforming in the direction of approaching each other. In this way, the side pillar collision performance of the vehicle can be improved, thereby improving the reliability of the vehicle.

[0012] In some embodiments, the battery mounting structure further includes two seals. The two seals are connected to the cover plate assembly and are located at opposite ends of the cover plate assembly in the direction in which the two door sills are arranged. Each seal corresponds to a door sill and contacts the corresponding door sill.

[0013] Based on the above technical means, some embodiments of the present disclosure can use a sealant to seal the gap between the cover plate assembly and the door sill beam, thereby reducing the risk of debris such as water and dust entering the installation cavity. This can reduce the risk of battery cell assembly failure and help reduce the failure rate of the vehicle.

The mounting portion is located on a side of the connecting portion away from the main portion, and is connected to the connecting portion.

[0021] According to the above technical means, some embodiments of the present disclosure can reduce the space occupied by the brake lines for the arrangement of battery cell components by arranging the brake lines in the grooves, which is conducive to further improving the space utilization of the lower vehicle body.

The battery cell assembly includes a first assembly, the first assembly being disposed between each set of two adjacent explosion-proof beams, with both ends of the first assembly in the extension direction of the sill beam respectively contacting the two adjacent explosion-proof beams.

[0041] Based on the above technical measures, some embodiments of the present disclosure can further enhance the structural strength of the cover body through the use of multiple explosion-proof beams, thereby providing more reliable protection for the battery cell assembly. Furthermore, the explosion-proof beams can also limit the expansion of the battery cells in the first assembly, thereby reducing the risk of damage to the battery cells in the first assembly and further improving the reliability of the vehicle.

[0042] In some embodiments, the mounting assembly includes a cover and a bottom guard plate. At least one explosion-proof beam is disposed on the cover. The bottom guard plate is located on the underside of the cover and is detachably connected to the cover. The bottom guard plate and the cover define a mounting cavity.

[0043] According to the above technical means, some embodiments of the present disclosure can separate the cover and the bottom guard plate to facilitate the repair or replacement of the battery cell assembly.

[0044] In some embodiments, the cover body includes a cover plate assembly and two support beams. The cover plate assembly is positioned opposite the bottom guard plate, and at least one explosion-proof beam is disposed on the cover plate assembly. The two support beams are positioned between the cover plate assembly and the bottom guard plate and connected to the cover plate assembly. The two support beams are positioned between the two threshold beams, with each support beam contacting the two threshold beams at its ends. The two support beams are positioned opposite each other and contacting the bottom guard plate, such that the bottom guard plate, the cover plate assembly, and the two support beams enclose a mounting cavity.

[0045] According to the above technical means, some embodiments of the present disclosure can support the rocker beam with two support beams to prevent the two rocker beams from deforming in the direction of approaching each other. In this way, the side pillar collision performance of the vehicle can be improved, thereby improving the reliability of the vehicle.

[0046] In some embodiments, the battery cell assembly further includes a second assembly disposed between at least one support beam and an explosion-proof beam adjacent to the at least one support beam, the second assembly being in contact with the adjacent explosion-proof beam and the adjacent support beam.

[0047] According to the above technical means, some embodiments of the present disclosure can limit the expansion of the battery cells in the second component through support beams and explosion-proof beams, thereby reducing the risk of damage to the battery cells in the second component and improving the reliability of the vehicle.

[0048] In some embodiments, the at least one explosion-proof beam includes a fixed beam, and the battery mounting structure further includes a seat crossbeam. The seat crossbeam is disposed on the cover body opposite the fixed beam and on a side of the cover body away from the bottom guard plate. The seat crossbeam extends along the alignment direction of the two door sill beams.

[0050] In some embodiments, the battery mounting structure further includes a fixing member disposed within the mounting cavity and connected to the fixing beam, configured to fix the battery cell assembly.

[0051] According to the above technical means, some embodiments of the present disclosure can improve the reliability of the installation of the battery cell assembly through fixing parts.

DETAILED DESCRIPTION

[0094] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0095] It should be noted that the terms "first," "second," and the like in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the numbers used in this manner are interchangeable where appropriate so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure as detailed in the appended claims.

[0096] Electric vehicles are one of the development directions of new energy vehicles, which mainly use power batteries as the power source to drive the vehicle.

[0097] Currently, as shown in Figure 1, Figure 1 is a structural diagram of a battery pack 01 and a vehicle body 02 in the related art. Vehicle manufacturers usually assemble battery cells or modules into a battery box to form a sealed battery pack 01, and then assemble the battery pack to the vehicle body 02 by bolting. The battery pack 01 and the vehicle body 02 are designed separately and need to meet their respective strength protection requirements. Sufficient space gaps need to be reserved in the installation area to compensate for manufacturing deviations and ensure that the battery pack 01 will not come into contact with the vehicle body 02 after being assembled in place. This results in low utilization of the lower body space, which not only increases the structural weight and cost of the vehicle, but also increases the space required for battery layout, sacrificing part of the vehicle space, especially the space in the vehicle height direction.

[0098] As shown in Figure 2, Figure 2 is an integrated structural diagram of a battery pack and a vehicle body in the related art, and Figure 2 is a partial exploded diagram of the integrated structure. The related art also provides a battery pack and vehicle integration solution with a Cell To Vehicle (CTV) structure. The battery box cover 03 is integrated with the seat 04, the seat mounting bracket 05, the passenger compartment floor 06, and the interior trim. When the battery system fails, it has a huge impact on the interior of the passenger compartment. The seat 04, the passenger compartment floor 06, the interior trim, and the battery box cover 03 need to be removed before the interior of the battery box can be repaired, diagnosed, and parts replaced. Part of the battery box cover 03 needs to be destructively disassembled before targeted maintenance can be carried out, which brings great difficulties and inconvenience to the maintenance of the battery system.

[0099] Furthermore, the current integrated structure of the battery cell and the battery case is often bonded using thermally conductive structural adhesive. Once the thermally conductive structural adhesive cures, the connection between the battery cell and the battery case cannot be replaced or maintained except by freezing or applying a debonding agent. Using a freezing solution can severely shorten the battery cell's service life, even rendering it scrapped. Similarly, applying a debonding agent can cause significant damage to the cell's blue film, making individual cell maintenance and replacement difficult.

[0100] Based on this, some embodiments of the present disclosure provide a battery mounting structure and a vehicle for improving the battery integration method of new energy vehicles to increase the space utilization of the lower body. For example, the vehicle can be a pure electric vehicle or a hybrid vehicle.

[0101] For ease of understanding, the battery installation structure provided in some embodiments of the present disclosure is introduced below with reference to the accompanying drawings.

[0102] As shown in FIG3 , FIG3 is a structural diagram of a battery mounting structure 100, a front compartment 200, and a rear floor 300 according to some embodiments of the present disclosure. Vehicle 1000 includes a battery mounting structure 100, a front compartment 200, and a rear floor 300. The front compartment 200 and the rear floor 300 are connected to opposite ends of the battery mounting structure 100. For example, the front compartment 200 is connected to the front end of the battery mounting structure 100, and the rear floor 300 is connected to the rear end of the battery mounting structure 100.

[0103] As shown in Figures 4A and 4B, Figure 4A is an exploded view of the battery mounting structure 100, the front compartment 200, and the rear floor 300 in some embodiments of the present disclosure, and Figure 4B is an exploded view of the battery mounting structure 100, the front compartment 200, and the rear floor 300 in some embodiments of the present disclosure from another perspective. The battery mounting structure 100 includes two door sill beams 1, which are arranged opposite to each other. In this case, the two ends of each door sill beam 1 are respectively connected to the front compartment 200 and the rear floor 300. In other words, the front compartment 200 is connected to the rear floor 300 through the two door sill beams 1.

[0104] In some embodiments, as shown in FIG5 , FIG5 is a structural diagram of a battery mounting structure 100 according to some embodiments of the present disclosure. The battery mounting structure 100 further includes a mounting assembly 2 and a battery cell assembly 3. The mounting assembly 2 defines a mounting cavity 22 having openings 21 at both ends, and the battery cell assembly 3 is disposed within the mounting cavity 22. For example, the battery cell assembly 3 includes a plurality of battery cells 31 (as shown in FIG4A and FIG4B ). The plurality of battery cells 31 can be used to provide electrical energy to the vehicle and serve as a power source for the vehicle.

[0105] On this basis, the two threshold beams 1 are connected to the mounting assembly 2, with each threshold beam 1 corresponding to an opening 21, and the threshold beam 1 covers the corresponding opening 21. In this way, the mounting assembly 2 and the two threshold beams 1 can enclose a closed space for accommodating the battery cell assembly 3.

[0106] In this configuration, the two sill beams 1 can replace part of the battery pack frame in related art. This allows the space for accommodating the battery cell assemblies 3 to expand toward the sill beams 1, increasing the space available for arranging the battery cell assemblies 3 and thereby improving the space utilization of the lower vehicle body. This allows the vehicle to accommodate more battery cells 31, increasing the vehicle's battery life and thus its range.

[0107] For example, as shown in Figures 4A and 4B , the mounting assembly 2 includes a cover 23 and a bottom guard plate 24. The bottom guard plate 24 is located on the underside of the cover 23 and, together with the cover 23, forms a mounting cavity 22. This facilitates the separation of the cover 23 and the bottom guard plate 24 for repair or replacement of the battery cell assembly 3.

[0108] At least one of the cover 23 or the bottom guard plate 24 is connected to the two sill beams 1. In other words, only the cover 23 may be connected to the two sill beams 1, only the bottom guard plate 24 may be connected to the two sill beams 1, or both the cover 23 and the bottom guard plate 24 may be connected to the two sill beams 1.

[0109] It is understandable that the cover 23 and the bottom guard plate 24 can be connected to the two door sill beams 1 by bolt connection, riveting, etc., which can be selected according to actual conditions and is not limited in this disclosure.

[0110] In some embodiments, as shown in Figures 6A and 6B, Figure 6A is a structural diagram of the cover body 23 of some embodiments of the present disclosure, and Figure 6B is a structural diagram of the cover body 23 of some embodiments of the present disclosure from another perspective. The cover body 23 may include a cover plate group 231 and two support beams 232. The cover plate group 231 is arranged opposite to the bottom guard plate 24 (as shown in Figures 4A and 4B). The two support beams 232 are located between the cover plate group 231 and the bottom guard plate 24 and are connected to the cover plate group 231. It will be understood that the two support beams 232 can be connected to the cover plate group 231 by welding, bolting, etc.

[0111] The two support beams 232 are arranged opposite to each other and contact the bottom guard plate 24 (as shown in Figures 4A and 4B). In this case, the bottom guard plate 24, the cover plate assembly 231 and the two support beams 232 form a mounting cavity 22 with openings 21 at both ends.

[0112] For example, as shown in Figures 5, 6A, and 6B, two support beams 232 are positioned between two sill beams 1, with each support beam 232 contacting both sill beams 1 at its ends. In this way, the two support beams 232 support the two sill beams 1, preventing them from deforming toward each other. This improves the vehicle's side-pillar collision resistance, thereby enhancing vehicle reliability.

[0113] In some embodiments, as shown in FIG7 , which is a partial structural diagram of a battery mounting structure 100 according to some embodiments of the present disclosure, the battery mounting structure 100 further includes two seals 4 . The two seals 4 are connected to the cover plate assembly 231 and are located at opposite ends of the cover plate assembly 231 in the direction of arrangement of the two door sill beams. Each seal 4 corresponds to a door sill beam 1 and contacts the corresponding door sill beam 1.

[0114] It is understood that the seal 4 can seal the gap between the cover plate assembly 231 and the door sill beam 1, thereby reducing the risk of debris such as water and dust entering the installation cavity 22. This can reduce the risk of failure of the battery cell assembly 3 and help reduce the failure rate of the vehicle.

[0115] For example, the sill beam 1 includes a main body 11 and a sealing portion 12. A cover plate assembly 231 is positioned between the two main bodies 11 of the sill beams 1. The sealing portion 12 is disposed on the side of the main body 11 that is closest to the cover plate assembly 231 and is connected to the main body 11. Furthermore, the seal 4 abuts against the surface of the sealing portion 12 that is away from the bottom guard plate 24.

[0116] In this way, the gap between the cover plate assembly 231 and the door sill beam 1 can be sealed by the seal 4 and the sealing portion 12 abutting each other, thereby improving the reliability of the seal and helping to further reduce the risk of debris such as water and dust entering the installation cavity 22, thereby reducing the failure rate of the vehicle.

[0117] It should be noted that the main body 11 and the sealing portion 12 can be integrally formed, thereby increasing the structural strength of the sill beam 1 and thus improving the side column collision performance of the vehicle, thereby increasing the reliability of the vehicle.

[0118] The main body 11 can be either a solid structure or a hollow structure, and can be selected according to actual conditions, which is not limited in this disclosure.

[0119] In some embodiments, as shown in FIG7 , the main body 11 is a hollow structure. This helps reduce the weight of the vehicle, thereby reducing vehicle energy consumption and increasing vehicle range. Furthermore, the hollow structure can cushion collisions, thereby improving vehicle reliability.

[0120] In this case, the main body 11 has a receiving cavity 111. The number of the receiving cavity 111 can be one or more, and can be selected according to actual conditions, and this disclosure does not limit this. For example, the main body 11 has multiple receiving cavities 111.

[0121] It should be noted that the battery mounting structure 100 may further include an air conditioning pipe 5, which is disposed in the accommodating cavity 111. The air conditioning pipe 5 is used to transmit refrigerant to enable the vehicle's air conditioning system to operate normally, thereby achieving cooling or heating of the vehicle interior and improving the vehicle's use effect.

[0122] It is understandable that arranging the air conditioning pipe 5 in the accommodating cavity 111 of the main body 11 can reduce the space occupied by the air conditioning pipe 5 for arranging the battery cell assembly 3, which is conducive to further improving the space utilization rate of the lower vehicle body.

[0123] In some embodiments, as shown in FIG7 , the door sill beam 1 further includes a connecting portion 13. The connecting portion 13 is located on a side of the main body 11 close to the bottom guard plate 24 and is connected to the main body 11. The connecting portion 13 can be integrally formed with the main body 11.

[0124] On this basis, the end of the bottom guard plate 24 near the sill beam 1 is located on the side of the connecting portion 13 away from the main body 11, and the end of the bottom guard plate 24 near the sill beam 1 is connected to the connecting portion 13. In other words, the end of the bottom guard plate 24 near the sill beam 1 is located below the connecting portion 13 and is connected to the connecting portion 13. The bottom guard plate 24 can be connected to the connecting portion 13 by bolting, snap-fitting, riveting, or other methods.

[0125] Arranged in this manner, it is convenient to remove the bottom guard plate 24 from the door sill beam 1 so as to repair or replace the battery cell assembly 3 in the installation cavity 22 .

[0126] For example, the bottom guard plate 24 includes a support portion 241, two recessed portions 242 and two mounting portions 243. Along the arrangement direction of the two door sill beams 1, the support portion 241 is located between the two recessed portions 242, and the support portion 241 is connected to the two recessed portions 242. The recessed portion 242 is recessed relative to the support portion 241 toward the direction close to the cover body to form a groove 2421. Along the arrangement direction of the two door sill beams 1, the two recessed portions 242 are located between the two mounting portions 243, and each mounting portion 243 is connected to the adjacent recessed portions 242. The mounting portion 243 is located on the side of the connecting portion 13 away from the main body 11, and is connected to the connecting portion 13. On this basis, the battery cell assembly 3 is arranged on the support portion 241.

[0127] It should be noted that the battery mounting structure 100 may also include a brake line 6 and a wiring harness 7. The brake line 6 is used to transmit a braking medium, for example, brake fluid. The wiring harness 7 is used to connect the battery cell assembly 3 with vehicle components to achieve transmission of electrical energy and data signals.

[0128] The brake line 6 and the wiring harness 7 can be connected to the bottom guard plate 24, and the brake line 6 and the wiring harness 7 can be arranged in the groove 2421. In this way, the space occupied by the brake line 6 and the wiring harness 7 on the arrangement of the battery cell assembly 3 can be reduced, which is conducive to further improving the space utilization of the lower body.

[0129] In some embodiments, the battery mounting structure 100 further includes a bottom cold plate. This bottom cold plate is disposed within the mounting cavity 22 and is located below the battery cell assembly 3 (i.e., on the side of the battery cell assembly 3 facing away from the mounting assembly 2). The bottom cold plate has a first cooling channel for conveying coolant. It should be noted that the first cooling channel can be connected to the vehicle's coolant flow line.

[0130] It is understood that the coolant can flow in the first cooling channel and then exchange heat with the battery cell assembly 3 through the bottom cold plate to remove the heat generated during the operation of the battery cell assembly 3. In this way, the heat dissipation efficiency of the battery cell assembly 3 can be improved and the risk of failure of the battery cell assembly 3 can be reduced.

[0131] For example, the bottom cold plate is in contact with the battery cell assembly 3. In this way, on the one hand, the heat dissipation efficiency of the battery cell assembly 3 can be further improved, and on the other hand, the bottom cold plate can provide support for the battery cell assembly 3, which is conducive to improving the stability of the installation of the battery cell assembly 3.

[0132] In some embodiments, as shown in Figures 6A and 6B , the battery mounting structure 100 further includes a seat crossbar 8. The seat crossbar 8 is disposed on the mounting assembly 2 and is located on the upper side of the mounting assembly 2 (as shown in Figure 5 ) (i.e., the side of the mounting assembly 2 away from the bottom guard plate 24). It should be noted that the seat crossbar 8 is used to mount the seat.

[0133] The seat cross beam 8 can be disposed on the cover body 23. For example, the seat cross beam 8 is disposed on the cover plate assembly 231 of the cover body 23.

[0134] It is understandable that the seat crossbar 8 can improve the structural strength of the mounting assembly 2. In this way, the mounting assembly 2 can provide more reliable protection for the battery cell assembly 3, which is conducive to improving the reliability of the vehicle.

[0135] For example, the seat cross member 8 extends along the alignment direction of the two rocker beams 1 (as shown in FIG5 ). This makes it easier for the mounting assembly 2 to deform in the alignment direction of the two rocker beams 1, thereby further improving the vehicle's side-pillar collision performance and, consequently, its reliability.

[0136] It should be noted that, as shown in FIG8 , FIG8 is an exploded view of the cover body 23 in some embodiments of the present disclosure. The cover plate assembly 231 may include a floor 2311 and a top cold plate 2312. The floor 2311 is disposed opposite the bottom guard plate 24 (shown in FIG7 ), and the seat crossbar 8 (shown in FIG6A and FIG6B ) is disposed on the floor 2311. The top cold plate 2312 is located between the floor 2311 and the bottom guard plate 24 and is connected to the floor 2311.

[0137] In this case, the two support beams 232 are located on a side of the top cold plate 2312 away from the floor 2311 and are connected to the top cold plate 2312 .

[0138] The top cold plate 2312 has a second cooling channel for transmitting coolant. It should be noted that the second cooling channel can be connected to the vehicle coolant flow pipeline.

[0139] It is understood that the coolant can flow in the second cooling channel and then exchange heat with the battery cell assembly 3 through the top cold plate 2312 to remove the heat generated during the operation of the battery cell assembly 3. In this way, the heat dissipation efficiency of the battery cell assembly 3 can be further improved and the risk of failure of the battery cell assembly 3 can be reduced.

[0140] For example, as shown in Figure 9, which illustrates the structure of a battery cell assembly 3, a binding strap 20, a fixing member 10, an explosion-proof beam 9, and a cover 23 in some embodiments of the present disclosure, a top cold plate 2312 is in contact with the battery cell assembly 3. This further improves the heat dissipation efficiency of the battery cell assembly 3.

[0141] It should be noted that the cover assembly 231 may also include only the floor panel 2311. In this case, the floor panel 2311 is positioned opposite the bottom guard panel 24. The two support beams 232 are located between the floor panel 2311 and the bottom guard panel 24 and connected to the floor panel 2311. In this case, the bottom guard panel 24, the floor panel 2311, and the two support beams 232 form the installation cavity 22.

[0142] It is understood that, when the cover assembly 231 includes a floor panel 2311, two seals 4 can be connected to the floor panel 2311, with the two seals 4 located at opposite ends of the floor panel 2311 in the direction in which the two door sill beams 1 are arranged. In this case, the mutually abutting seals 4 and the sealing portion 12 can seal the gap between the floor panel 2311 and the door sill beam 1.

[0143] 5 , 6A and 6B , the battery mounting structure 100 further includes at least one explosion-proof beam 9 . The explosion-proof beam 9 is disposed on the mounting assembly 2 and is located within the mounting cavity 22 .

[0144] The explosion-proof beam 9 can be arranged on the cover body 23. For example, the explosion-proof beam 9 is arranged on the cover plate group 231 of the cover body 23.

[0145] It is understandable that the explosion-proof beam 9 can improve the structural strength of the cover 23 in the mounting assembly 2. In this way, the cover 23 in the mounting assembly 2 can provide more reliable protection for the battery cell assembly 3, which is conducive to improving the reliability of the vehicle.

[0146] For example, the explosion-proof beams 9 extend along the alignment of the two sill beams 1, with both ends of each explosion-proof beam 9 contacting the two sill beams 1. In this way, the explosion-proof beams 9 can support the sill beams 1 to prevent the two sill beams 1 from deforming toward each other, thereby further improving the vehicle's side-pillar collision performance and enhancing vehicle reliability.

[0147] The number of explosion-proof beams 9 can be one or more, depending on the actual situation, and is not limited in this disclosure. For example, the battery mounting structure 100 includes multiple explosion-proof beams 9, and the multiple explosion-proof beams 9 are spaced apart along the extension direction (e.g., the front-to-back direction) of the sill beam 1. The extension direction of the sill beam 1 is perpendicular to the arrangement direction of the two sill beams 1.

[0148] It can be understood that the multiple explosion-proof beams 9 can further improve the structural strength of the cover body 23, thereby providing more reliable protection for the battery cell assembly 3.

[0149] When the battery mounting structure 100 includes multiple explosion-proof beams 9, as shown in FIG9 , the battery cell assembly 3 may include a first assembly 32. The first assembly 32 is disposed between two adjacent explosion-proof beams 9 in each group, and the first assembly 32 contacts the two adjacent explosion-proof beams 9 at both ends in the extension direction of the door sill beam 1.

[0150] It is understood that the first component 32 includes a plurality of battery cells 31. For example, the plurality of battery cells 31 of the first component 32 are arranged in a rectangular array along the horizontal direction, and two adjacent battery cells 31 in the first component 32 are in contact with each other.

[0151] Arranged in this manner, the explosion-proof beam 9 can also limit the expansion of the battery cells 31 in the first assembly 32, thereby reducing the risk of damage to the battery cells 31 in the first assembly 32 and improving the reliability of the vehicle.

[0152] In addition, the battery cell assembly 3 may further include a second assembly 33. The second assembly 33 is disposed between at least one support beam 232 and an explosion-proof beam 9 adjacent to the at least one support beam 232, and the second assembly 33 contacts the adjacent explosion-proof beam 9 and the adjacent support beam 232.

[0153] It is understood that the second component 33 includes a plurality of battery cells 31. For example, the plurality of battery cells 31 of the second component 33 are arranged in a rectangular array along the horizontal direction, and two adjacent battery cells 31 in the second component 33 are in contact with each other.

[0154] Arranged in this manner, the support beam 232 and the explosion-proof beam 9 can also limit the expansion of the battery cells 31 in the second assembly 33, thereby reducing the risk of damage to the battery cells 31 in the second assembly 33 and improving the reliability of the vehicle.

[0155] In some embodiments, as shown in Figures 6A and 6B , at least one explosion-proof beam 9 includes a fixed beam 91. The seat cross beam 8 is disposed on the cover 23 at a position opposite to the fixed beam 91, and the seat cross beam 8 and the explosion-proof beam 9 extend along the arrangement direction of the two door sill beams 1 (as shown in Figure 5 ).

[0156] That is, as shown in Figures 10A and 10B, Figure 10A is an enlarged view of the battery mounting structure 100 at the fixed beam 91 in some embodiments of the present disclosure, and Figure 10B is an enlarged view of the battery mounting structure 100 at the fixed beam 91 in some embodiments of the present disclosure from another perspective. The seat cross beam 8 and the fixed beam 91 are located on opposite sides of the cover 23, and the seat cross beam 8 and the fixed beam 91 are positioned relative to each other. In this way, the seat cross beam 8 and the fixed beam 91 can reinforce each other. In this way, on the one hand, it can provide more stable support for the seat, and on the other hand, it can further improve the side column collision performance of the vehicle, thereby improving the reliability of the vehicle.

[0157] It should be noted that the battery mounting structure 100 may further include a fixing member 10 . The fixing member 10 is disposed in the mounting cavity 22 (as shown in FIG. 5 ) and connected to the fixing beam 91 .

[0158] The fixing member 10 can be used to fix the battery core assembly 3. For example, the fixing member 10 can be connected to the battery core assembly 3 by screw connection, snap connection, etc., so as to fix the battery core assembly 3.

[0159] It can be understood that the fixing member 10 can improve the reliability of the installation of the battery cell assembly 3 .

[0160] In some embodiments, as shown in FIG9 , the battery mounting structure 100 further includes a strap 20 . The strap 20 is disposed within the mounting cavity 22 and connected to the cover 23 . The strap 20 and the cover 23 enclose a fixed space, and the battery cell assembly 3 is located within the fixed space.

[0161] As shown in FIG4A and FIG4B , along the arrangement direction of the cover 23 and the bottom guard plate 24 , the battery cell assembly 3 has a first end and a second end facing each other. The first end abuts against the cover 23 , and the second end abuts against the binding band 20 .

[0162] Arranged in this manner, the binding band 20 can restrict the battery cell assembly 3 from moving in a direction away from the cover 23 , thereby further improving the reliability of the installation of the battery cell assembly 3 .

[0163] For example, as shown in FIG9 , there are multiple straps 20 , and each row of cells 31 of each first assembly 32 corresponds to a strap 20 and abuts against the corresponding strap 20 . Similarly, each row of cells 31 of each second assembly 33 corresponds to a strap 20 and abuts against the corresponding strap 20 .

[0164] It should be noted that the strap 20 can be connected to the explosion-proof beam 9, the support beam 232, or the cover plate group 231. The selection can be made according to actual conditions, and this disclosure does not limit this.

[0165] Some embodiments of the present disclosure further provide a vehicle 1000. Fig. 11 is a block diagram of a vehicle 1000 according to some embodiments of the present disclosure. As shown in Fig. 11, the vehicle 1000 includes the above-mentioned battery mounting structure.

[0166] The above are only specific embodiments of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or replacements within the technical scope disclosed in the present disclosure should be included in the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be based on the scope of protection of the claims.
