Description

Technical Field

[0001] The present application relates to the field of automotive technology, and in particular to a battery mounting structure and a vehicle. Background Art

[0002] 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.

[0003] In related technologies, vehicle manufacturers typically assemble battery cells or modules into a battery case to form a sealed battery pack, which is then bolted to the vehicle body. The battery pack and vehicle body are designed independently and must meet their own strength and protection requirements. Sufficient clearance is also required in the installation area to accommodate manufacturing variations and ensure proper assembly without movement or contact. This results in low utilization of the lower body space, increasing the vehicle's structural weight and cost while also increasing the space required for battery placement and sacrificing some overall vehicle space, particularly in terms of height. Summary of the Invention

[0004] This application provides a battery installation structure and vehicle for improving the battery integration method of new energy vehicles to increase the utilization rate of the lower vehicle body space. The technical solution of this application is as follows:

[0005] According to a first aspect of the present application, a battery mounting structure is provided, which includes a mounting assembly, a battery cell assembly, a seat crossbeam, and two door sill beams.

[0006] The mounting assembly defines a mounting cavity with openings at both ends, within which the battery cell assembly is mounted. A seat crossbar is mounted on the mounting assembly and located above it. The seat crossbar is used to mount the seat. Two door sills are positioned opposite each other and connected to the mounting assembly. Each door sill corresponds to an opening and covers the corresponding opening.

[0007] Based on the above technical means, the present application can replace part of the battery pack frame in the related art with two door sill beams. This allows the space for accommodating the battery cell components to expand closer to the door sill beams, which helps increase the space for accommodating the battery cell components and thus improve the utilization of the lower vehicle body space. This allows the vehicle to accommodate more battery cells, increasing the vehicle's power capacity and thus improving the vehicle's range. In addition, the seat crossbar can increase the structural strength of the mounting assembly, thus providing more reliable protection for the battery cell components and improving vehicle safety.

[0008] In a possible embodiment, the seat cross member extends along an arrangement direction of the two door sill beams.

[0009] According to the above technical means, the present application can increase the deformation difficulty of the installation component in the arrangement direction of the two rocker beams, thereby further improving the side column collision performance of the vehicle and further improving the safety performance of the vehicle.

[0010] In one possible embodiment, the battery mounting structure further includes a bottom cold plate. The bottom cold plate is disposed within the mounting cavity and below the battery cell assembly. The bottom cold plate has a first cooling channel for transmitting coolant.

[0011] According to the above technical means, the present application can exchange heat with the battery cell assembly through the bottom cold plate to remove the heat generated by the battery cell assembly during operation. In this way, the heat dissipation efficiency of the battery cell assembly can be improved and the risk of battery cell assembly failure can be reduced.

[0012] In one possible embodiment, the mounting assembly includes a cover and a bottom guard plate. The seat crossbar is disposed on the cover. 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. The cover has a second cooling channel for transmitting coolant.

[0013] According to the above technical means, the present application can disassemble the cover and the bottom guard plate to facilitate the repair or replacement of the battery cell components.

[0014] In one possible embodiment, the cover body includes a cover assembly and two support beams. The cover assembly is positioned opposite the underbody, and the seat crossbeam is mounted on the cover assembly. The two support beams are positioned between the cover assembly and the underbody and connected to the cover assembly. The two support beams are positioned between the two door sill beams, with each support beam contacting the two door sill beams at its ends. The two support beams are positioned opposite each other and contact the underbody, so that the underbody, cover assembly, and two support beams enclose a mounting cavity.

[0015] According to the above technical means, the present application can support the sill beam by two support beams to prevent the two sill beams from deforming in the direction of approaching each other. In this way, the side column collision performance of the vehicle can be improved, thereby improving the safety performance of the vehicle.

[0016] In one possible embodiment, the cover assembly includes a floor and a top cooling plate. The floor is positioned opposite the bottom guard plate, and the seat crossbar is disposed on the floor. The top cooling plate is located between the floor and the bottom guard plate and is connected to the floor. Two support beams are located on the side of the top cooling plate away from the floor and are connected to the top cooling plate. The top cooling plate has a second cooling channel.

[0017] According to the above technical means, the present application can exchange heat with the battery cell assembly through the top cold plate to remove the heat generated by the battery cell assembly during operation. In this way, the heat dissipation efficiency of the battery cell assembly can be improved and the risk of battery cell assembly failure can be reduced.

[0018] In a possible embodiment, the battery installation structure further includes at least one explosion-proof beam, which is disposed on the cover and located within the installation cavity.

[0019] According to the above technical means, the present application can improve the structural strength of the cover body through the explosion-proof beam, so that the cover body can provide more reliable protection for the battery cell assembly, which is conducive to improving the safety of the vehicle.

[0020] In a possible implementation, the explosion-proof beam extends along the arrangement direction of the two door sill beams, and both ends of each explosion-proof beam are in contact with the two door sill beams respectively.

[0021] According to the above technical means, the present application can support the sill beam with the explosion-proof beam to prevent the two sill beams from deforming in the direction of approaching each other. In this way, the vehicle's side column collision performance can be further improved, thereby improving the vehicle's safety performance.

[0022] In a possible implementation, there are multiple explosion-proof beams, and the multiple explosion-proof beams are arranged at intervals along the extension direction of the door sill beam.

[0023] According to the above technical means, the present application can further improve the structural strength of the cover through multiple explosion-proof beams, thereby providing more reliable protection for the battery cell assembly.

[0024] According to a second aspect provided by the present application, a vehicle is provided, which includes the battery mounting structure of the above-mentioned first aspect and any possible embodiment thereof.

[0025] Therefore, the above technical features of this application have the following beneficial effects:

[0026] (1) Two door sill beams can replace part of the battery pack frame in the related art. In this way, the space for accommodating the battery cell assembly can be expanded in the direction close to the door sill beam, which is conducive to increasing the layout space of the battery cell assembly, thereby improving the utilization rate of the lower body space. In this way, the vehicle can be equipped with more battery cells to increase the vehicle's power, thereby improving the vehicle's cruising range. In addition, the seat crossbeam can improve the structural strength of the installation assembly. In this way, the installation assembly can provide more reliable protection for the battery cell assembly, which is conducive to improving the safety of the vehicle.

[0027] (2) The deformation difficulty of the mounting assembly in the arrangement direction of the two rocker beams can be increased, thereby further improving the side column collision performance of the vehicle and further improving the safety performance of the vehicle.

[0028] (3) The bottom cold plate can exchange heat with the battery cell assembly to remove the heat generated by the battery cell assembly during operation. This can improve the heat dissipation efficiency of the battery cell assembly and reduce the risk of battery cell assembly failure.

[0029] (4) The cover and bottom guard plate can be disassembled to facilitate the repair or replacement of the battery cell components.

[0030] (5) The sill beam can be supported by two support beams to prevent the two sill beams from deforming in the direction of approaching each other. In this way, the side column collision performance of the vehicle can be improved, thereby improving the safety performance of the vehicle.

[0031] (6) The top cold plate can exchange heat with the battery cell assembly to remove the heat generated by the battery cell assembly during operation. This can improve the heat dissipation efficiency of the battery cell assembly and reduce the risk of battery cell assembly failure.

[0032] (7) The structural strength of the cover can be improved by using explosion-proof beams. In this way, the cover can provide more reliable protection for the battery cell components, which is conducive to improving the safety of the vehicle.

[0033] (8) The sill beams can be supported by explosion-proof beams to prevent the two sill beams from deforming in the direction of approaching each other. In this way, the side column collision performance of the vehicle can be further improved, thereby improving the safety performance of the vehicle.

[0034] (9) The structural strength of the cover can be further improved by using multiple explosion-proof beams, thereby providing more reliable protection for the battery cell components.

DETAILED DESCRIPTION

[0050] In order to enable ordinary people in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0051] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying 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 terms used in this manner are interchangeable where appropriate so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0052] 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.

[0053] Currently, see Figure 1 , Figure 1 This is a schematic diagram of the structure of a battery pack 01 and a vehicle body 02, as provided by related technologies. Vehicle manufacturers typically assemble battery cells or modules into a battery case to form a sealed battery pack 01, and then bolt the battery pack to the vehicle body 02. Battery pack 01 and vehicle body 02 are designed independently and must meet their respective strength and protection requirements. Sufficient clearance is also required in the installation area to accommodate manufacturing deviations and ensure proper assembly without movement or contact. This results in low utilization of the lower vehicle body space, which not only increases the structural weight and cost of the vehicle, but also increases the space required for battery placement, sacrificing some vehicle space, particularly in the vehicle's height.

[0054] like Figure 2 As shown, Figure 2 This is a schematic diagram of the integrated structure of a battery pack and vehicle body provided by the related art. The related art also provides a cell-to-vehicle (CTV) structure battery pack and vehicle integration solution. The battery case cover 03 is integrated with the seat 04, seat mounting bracket 05, passenger compartment floor 06, and interior trim. When a battery system malfunctions, it has a significant impact on the interior of the passenger compartment. The seat 04, passenger compartment floor 06, interior trim, and battery case cover 03 must be removed before repairs, diagnosis, and parts replacement can be performed inside the battery case. Some battery case covers 03 require destructive disassembly for targeted maintenance, creating significant difficulties and inconvenience in maintaining the battery system.

[0055] Furthermore, the integrated structure of the battery cell and the battery case is currently mostly bonded using thermally conductive structural adhesive. Once the thermally conductive structural adhesive cures, the gap 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.

[0056] Based on this, the present application provides a vehicle for improving the battery integration method of new energy vehicles to improve the utilization rate of the lower body space. The vehicle can be a pure electric vehicle or a hybrid vehicle.

[0057] For ease of understanding, the vehicle provided in this application is described in detail below with reference to the accompanying drawings.

[0058] like Figure 3 As shown, Figure 3 Schematic diagram of the battery mounting structure 100, front compartment 200, and rear floor 300 provided in some embodiments of the present application. The vehicle includes the battery mounting structure 100, front compartment 200, and rear floor 300, with the front compartment 200 and rear floor 300 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.

[0059] Among them, see Figure 4 , Figure 4 This is an exploded view of the battery mounting structure 100, front compartment 200, and rear floor 300 provided in some embodiments of the present application. The battery mounting structure 100 includes two sill beams 1, which are arranged opposite each other. In this case, each sill beam 1 is connected to the front compartment 200 and rear floor 300 at its ends, respectively. In other words, the front compartment 200 is connected to the rear floor 300 via the two sill beams 1.

[0060] In some embodiments, as Figure 5 As shown, Figure 5 1 is a schematic diagram of the structure of a battery mounting structure 100 provided in some embodiments of the present application. The battery mounting structure 100 further includes a mounting assembly 2 and a battery cell assembly 3. The mounting assembly 2 forms a mounting cavity 22 with openings 21 at both ends. The battery cell assembly 3 is disposed in the mounting cavity 22. The battery cell assembly 3 includes a plurality of battery cells 31 (e.g., Figure 4 As shown in the figure, it can be used to provide electrical energy for the vehicle and is the power source of the vehicle.

[0061] 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.

[0062] 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 for arranging the battery cell assemblies 3 and thereby improving the utilization of the lower vehicle body space. This allows the vehicle to accommodate more battery cells 31, increasing the vehicle's power reserve and thus its range.

[0063] For example, Figure 4 As shown, 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 forms a mounting cavity 22 with the cover 23. This makes it easy to separate the cover 23 and the bottom guard plate 24 to repair or replace the battery cell assembly 3.

[0064] At least one of the cover 23 and 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.

[0065] 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. The specific selection can be made according to actual conditions, and this application does not make any specific restrictions on this.

[0066] It should be noted that, see Figure 6 , Figure 6 23 is a structural diagram of the cover body 23 provided in some embodiments of the present application. The cover body 23 may include a cover plate assembly 231 and two support beams 232. The cover plate assembly 231 and the bottom guard plate 24 (such as Figure 4 The two support beams 232 are located between the cover plate assembly 231 and the bottom guard plate 24 and are connected to the cover plate assembly 231. It is understood that the two support beams 232 can be connected to the cover plate assembly 231 by welding, bolting, etc.

[0067] The two support beams 232 are arranged opposite to each other and are connected to the bottom guard plate 24 (such as Figure 4 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.

[0068] For example, see Figure 5 and Figure 6The two support beams 232 are located between the two sill beams 1, with each end of the support beam 232 contacting the two sill beams 1. This way, the two support beams 232 support the sill beams 1, preventing them from deforming toward each other. This improves the vehicle's side-pillar collision resistance, thereby enhancing vehicle safety.

[0069] In some embodiments, see Figure 7 , Figure 7 This is a partial structural diagram of a battery mounting structure 100 provided in some embodiments of the present application. The battery mounting structure 100 also includes two seals 4. These seals 4 are connected to the cover plate assembly 231 and are located at opposite ends of the cover plate assembly 231. Each seal 4 corresponds to a sill beam 1 and contacts the corresponding sill beam 1.

[0070] It is understood that the seal 4 can seal the gap between the cover assembly 231 and the door sill beam 1, thereby reducing the risk of debris such as water and dust entering the installation cavity 22. In this way, the risk of failure of the battery cell assembly 3 can be reduced, which is conducive to reducing the failure rate of the vehicle.

[0071] Exemplarily, 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 a side of the main body 11 proximal 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 facing away from the underbody guard 24.

[0072] In this way, the gap between the cover assembly 231 and the door sill beam 1 can be sealed by the mutually abutting seal 4 and the sealing portion 12. This can improve the reliability of the seal and help further reduce the risk of debris such as water and dust entering the installation cavity 22, thereby reducing the failure rate of the vehicle.

[0073] It should be noted that the main body 11 and the sealing portion 12 can be integrally formed, so that the structural strength of the rocker beam 1 can be increased, thereby improving the side column collision performance of the vehicle and further improving the safety performance of the vehicle.

[0074] The main body 11 can be either a solid structure or a hollow structure, and the specific selection can be made according to actual conditions. This application does not make any specific restrictions on this.

[0075] For example, Figure 7 As shown, 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. In addition, the hollow structure can also cushion collisions, which helps improve vehicle safety.

[0076] 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 application does not make specific restrictions on this. For example, the number of the receiving cavity 111 is more than one.

[0077] It should be noted that the battery mounting structure 100 may further include an air conditioning pipe 5, which is disposed within 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 providing a comfortable driving environment for the occupants.

[0078] 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 utilization rate of the lower body space.

[0079] In some embodiments, as Figure 7 As shown, 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.

[0080] 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 bolts, snaps, rivets, etc.

[0081] 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 .

[0082] Exemplarily, 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 cover plate, and a groove 2421 is formed. 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 an adjacent recessed portion 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.

[0083] 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, such as brake fluid. The wiring harness 7 is used to connect the battery cell assembly 3 and vehicle components to achieve the transmission of electrical energy and data signals.

[0084] The brake line 6 and the wiring harness 7 can be connected to the bottom guard plate 24 and placed in the groove 2421. This can reduce the space occupied by the brake line 6 and the wiring harness 7 for arranging the battery cell assembly 3, thereby further improving the utilization rate of the lower vehicle body space.

[0085] 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 below the battery cell assembly 3. The bottom cold plate has a first cooling channel for transmitting coolant. It should be noted that the first cooling channel can be connected to the vehicle's coolant flow line.

[0086] 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 by the battery cell assembly 3 during operation. In this way, the heat dissipation efficiency of the battery cell assembly 3 can be improved and the risk of battery cell assembly 3 failure can be reduced.

[0087] 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.

[0088] In some embodiments, see Figure 6 The battery installation structure 100 further includes a seat crossbeam 8. The seat crossbeam 8 is provided on the installation component 2 and is located at the installation component 2 (e.g. Figure 5 It should be noted that the seat crossbar 8 is used to install the seat.

[0089] The seat cross beam 8 may 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 .

[0090] It can be understood that the seat crossbeam 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 beneficial to improving the safety of the vehicle.

[0091] For example, the seat crossbar 8 is arranged along the two door sill beams 1 (eg Figure 5 In this way, the deformation difficulty of the mounting assembly 2 in the arrangement direction of the two rocker beams 1 can be increased, thereby further improving the side column collision performance of the vehicle and further improving the safety performance of the vehicle.

[0092] It should be noted that, see Figure 8 , Figure 8 23 is an exploded view of the cover body 23 provided in some embodiments of the present application. The cover assembly 231 may include a floor 2311 and a top cold plate 2312. The floor 2311 and the bottom guard plate 24 (such as Figure 7 As shown) are relatively arranged, and the seat crossbeam 8 (as shown Figure 6 The top cold plate 2312 is located between the floor 2311 and the bottom guard plate 24 and is connected to the floor 2311.

[0093] 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 .

[0094] 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.

[0095] 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 by the battery cell assembly 3 during operation. In this way, the heat dissipation efficiency of the battery cell assembly 3 can be further improved, and the risk of battery cell assembly 3 failure can be reduced.

[0096] For example, Figure 9 As shown, Figure 9 This is a schematic diagram of the structure of the battery cell assembly 3, the binding strap 20, the fixing member 10, the explosion-proof beam 9, and the cover 23 provided in some embodiments of the present application. The top cold plate 2312 is in contact with the battery cell assembly 3. This can further improve the heat dissipation efficiency of the battery cell assembly 3.

[0097] 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.

[0098] It is understood that when the cover assembly 231 includes a floor panel 2311, two seals 4 can be provided to be connected to the floor panel 2311, with the two seals 4 being located at opposite ends of the floor panel 2311. 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.

[0099] In some embodiments, see Figure 5 and Figure 6The 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 .

[0100] The explosion-proof beam 9 may be disposed on the cover body 23 , for example, the explosion-proof beam 9 is disposed on the cover plate assembly 231 of the cover body 23 .

[0101] It can be understood that the explosion-proof beam 9 can improve the structural strength of the cover 23 in the installation component 2. In this way, the cover 23 in the installation component 2 can provide more reliable protection for the battery cell assembly 3, which is conducive to improving the safety of the vehicle.

[0102] For example, the explosion-proof beams 9 extend along the alignment of the two sill beams 1, with each end of the explosion-proof beam 9 contacting the two sill beams 1. This supports the sill beams 1, preventing them from deforming toward each other. This further improves the vehicle's side-pillar collision resistance, thereby enhancing vehicle safety.

[0103] The number of explosion-proof beams 9 can be one or more, and can be selected according to actual conditions, and this application does not make specific restrictions on this. For example, the number of explosion-proof beams 9 is multiple, and the multiple explosion-proof beams 9 are spaced apart along the extension direction of the threshold beam 1.

[0104] 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.

[0105] In the case where the number of explosion-proof beams 9 is multiple, see Figure 9 The battery cell assembly 3 may include a first assembly 32. A first assembly 32 is provided between each two adjacent explosion-proof beams 9, and both ends of the first assembly 32 in the first direction are in contact with the two adjacent explosion-proof beams 9 respectively.

[0106] It is understood that the first component 32 includes a plurality of battery cells 31. Exemplarily, the plurality of battery cells 31 of the first component 32 are arranged in a rectangular array along the horizontal direction, and every two adjacent battery cells 31 are in contact with each other.

[0107] Arranged in this manner, the explosion-proof beam 9 can also limit the expansion of the battery cells 31 in the first component 32, thereby reducing the risk of damage to the battery cells 31 in the first component 32 and further improving the safety performance of the vehicle.

[0108] In addition, the battery cell assembly 3 may further include a second assembly 33. A second assembly 33 is provided between at least one support beam 232 and an adjacent explosion-proof beam 9. The second assembly 33 contacts the adjacent explosion-proof beam 9 and the second assembly 33 contacts the adjacent support beam 232.

[0109] It is understood that the second component 33 includes a plurality of battery cells 31. Exemplarily, the plurality of battery cells 31 of the second component 33 are arranged in a rectangular array along the horizontal direction, and every two adjacent battery cells 31 are in contact with each other.

[0110] 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 component 33, thereby reducing the risk of damage to the battery cells 31 in the second component 33 and improving the safety performance of the vehicle.

[0111] In some embodiments, see Figure 6 , at least one explosion-proof beam 9 includes a fixed beam 91, the seat cross beam 8 is arranged at a position opposite to the cover 23 and the fixed beam 91, and the seat cross beam 8 and the explosion-proof beam 9 are arranged along the two door sill beams 1 (such as Figure 5 The arrangement direction shown) extends.

[0112] That is to say, if Figure 10 As shown, Figure 10 This is an enlarged view of the battery mounting structure 100 at the fixed beam 91, provided in some embodiments of the present application. The seat cross beam 8 and the fixed beam 91 are located on opposite sides of the cover 23, and their positions are opposite each other. This reinforces the seat cross beam 8 and the fixed beam 91, providing more stable support for the seat and further improving the vehicle's side-pillar collision resistance, thereby enhancing vehicle safety.

[0113] 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 (eg Figure 5 as shown) and is connected to the fixed beam 91.

[0114] The fixing member 10 can be used to fix the battery cell assembly 3. For example, the fixing member 10 can be connected to the battery cell assembly 3 by screw connection, snap connection, etc., so as to fix the battery cell assembly 3.

[0115] It can be understood that the fixing member 10 can improve the reliability of the installation of the battery cell assembly 3 .

[0116] In some embodiments, see Figure 9 The battery mounting structure 100 further includes a strap 20. The strap 20 is disposed in the mounting cavity 22 and is connected to the cover 23. The strap 20 and the cover 23 enclose a fixed space, and the battery cell assembly 3 is located in the fixed space.

[0117] Among them, see Figure 4 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 .

[0118] 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 .

[0119] For example, Figure 9 As shown, 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.

[0120] It should be noted that the strap 20 can be connected to the explosion-proof beam 9, the support beam 232, or the cover assembly 231. The specific selection can be made according to actual conditions, and this application does not make any specific restrictions on this.

[0121] The above are only specific embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any changes or replacements within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
