DETAILED DESCRIPTION

[0074] In order to enable a person of ordinary skill 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 described clearly and completely below with reference to the accompanying drawings.

[0075] It should be noted that the terms “first”, “second”, etc. in the description 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 sequence. It should be understood that the data so used may be interchanged under appropriate circumstances so that the embodiments of the present disclosure described herein can be practiced in sequences other than those illustrated or described herein. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0076] An electric vehicle is one of development directions of a new energy vehicle, and the electric vehicle mainly uses a power battery as a power source to drive the vehicle.

[0077] Currently, as shown in FIG. 1, FIG. 1 is a structural diagram of a battery pack 01 and a vehicle body 02 in related art. A complete vehicle manufacturer generally first assembles battery cells or modules into a battery box to provide a sealed battery pack 01, and then assembles the battery pack onto the vehicle body 02 by means of bolt connection. The battery pack 01 and the vehicle body 02 are designed independently and need to meet their respective strength protection requirements, and sufficient space clearance needs to be reserved in an installation region, so as to compensate for a manufacturing deviation, ensuring that the battery pack 01 does not come into moving contact with the vehicle body 02 after being assembled in place. In this way, resulting in excessively low space utilization rate of a lower body, which not only increases a structural weight and a cost of a complete vehicle, but also increases a space required for battery layout, sacrificing a part of a vehicle space, especially in a height direction of a vehicle.

[0078] As shown in FIG. 2, FIG. 2 is a diagram of an integrated structure of a battery pack and a vehicle body in related art, and FIG. 2 is a partial exploded view of the integrated structure. The related art further provides a battery pack and a complete vehicle integration solution of a cell to vehicle (CTV) structure. A battery box upper cover 03 is integrated with a seat 04, a seat mounting bracket 05, a passenger compartment floor 06, and interior trim parts. Upon a battery system fails, it has a huge impact on an interior of a passenger compartment, and it is necessary to remove the seat 04, the passenger compartment floor 06, the interior trim parts, and the battery box upper cover 03 before repairing, diagnosing, or replacing parts inside the battery box. A part of the battery box upper cover 03 needs to be destructively disassembled to perform targeted maintenance, which causes great difficulties and inconvenience for a maintenance and care of the battery system.

[0079] Moreover, currently, an integrated structure of a cell and a battery box mostly adopts thermally conductive structural adhesive bonding. After the thermally conductive structural adhesive is cured, the cell and the battery box cannot be replaced or maintained except by freezing or applying a release agent. Adopting a freezing solution will seriously affect a service life of the cell, or even cause the cell to be scrapped. Similarly, applying a release agent may cause irreversible damage to a blue film of the cell, and it is difficult to achieve maintenance and replacement of a single cell.

[0080] Based on this, some embodiments of the present disclosure provide a battery mounting structure and a vehicle for improving a battery integration manner of a new energy vehicle, so as to improve a space utilization rate of a lower body. For example, the vehicle may be a pure electric vehicle or the vehicle may be a hybrid electric vehicle.

[0081] For ease of understanding, the battery mounting structure provided by some embodiments of the present disclosure is described below with reference to the accompanying drawings.

[0082] As shown in FIG. 3, FIG. 3 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. A 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 two opposite ends of the battery mounting structure 100. For example, the front compartment 200 is connected to a front end of the battery mounting structure 100, and the rear floor 300 is connected to a rear end of the battery mounting structure 100.

[0083] As shown in FIG. 4A and FIG. 4B, FIG. 4A is an exploded view of a battery mounting structure 100, a front compartment 200, and a rear floor 300 according to some embodiments of the present disclosure, and FIG. 4B is an exploded view of the battery mounting structure 100, the front compartment 200, and the rear floor 300 from another perspective according to some embodiments of the present disclosure. The battery mounting structure 100 includes two sill beams 1, and the two sill beams 1 are disposed opposite to each other. In this case, two ends of each sill beam 1 are respectively connected to the front compartment 200 and the rear floor 300. That is to say, the front compartment 200 is connected to the rear floor 300 through the two sill beams 1.

[0084] In some embodiments, as shown in FIG. 5, FIG. 5 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 cell assembly 3. The mounting assembly 2 encloses a mounting cavity 22 having openings 21 at two ends, respectively, and the cell assembly 3 is disposed in the mounting cavity 22. For example, the cell assembly 3 includes a plurality of cells 31 (as shown in FIG. 4A and FIG. 4B), and the plurality of cells 31 may be used to provide electrical energy for the vehicle and are a power source of the vehicle.

[0085] On this basis, the two sill beams 1 are connected to the mounting assembly 2, each sill beam 1 corresponds to an opening 21, and the sill beam 1 covers a corresponding opening 21. In this way, the mounting assembly 2 and the two sill beams 1 may enclose a closed space for accommodating the cell assembly 3.

[0086] Arranged in such manner, the two sill beams 1 can replace a part of a frame of a battery pack in the related art. In this way, the space for accommodating the cell assembly 3 can be expanded in a direction close to the sill beams 1, which is conducive to increasing the layout space for the cell assembly 3, thereby improving the space utilization rate of the lower body. In this way, the vehicle can be arranged with more cells 31 to increase a battery capacity of the vehicle, thereby improving a cruising range of the vehicle.

[0087] For example, as shown in FIG. 4A and FIG. 4B, the mounting assembly 2 includes a cover body 23 and a bottom guard plate 24. The bottom guard plate 24 is located on a lower side of the cover body 23 and encloses the mounting cavity 22 together with the cover body 23. In this way, it is convenient to separate the cover body 23 and the bottom guard plate 24, so as to repair or replace the cell assembly 3.

[0088] At least one of the cover body 23 or the bottom guard plate 24 is connected to the two sill beams 1. That is, it may be that only the cover body 23 is connected to the two sill beams 1, or it may be that only the bottom guard plate 24 is connected to the two sill beams 1, or it may be that both the cover body 23 and the bottom guard plate 24 are connected to the two sill beams 1.

[0089] It can be understood that the cover body 23 and the bottom guard plate 24 may be connected to the two sill beams 1 by means such as bolting or riveting, which may be selected according to an actual condition, and the present disclosure is not limited thereto.

[0090] In some embodiments, as shown in FIG. 6A and FIG. 6B, FIG. 6A is a structural diagram of a cover body 23 according to some embodiments of the present disclosure, and FIG. 6B is a structural diagram of the cover body 23 from another perspective according to some embodiments of the present disclosure. The cover body 23 may include a cover plate group 231 and two supporting beams 232. The cover plate group 231 is disposed opposite to the bottom guard plate 24 (as shown in FIG. 4A and FIG. 4B). The two supporting 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 can be understood that the two supporting beams 232 may be connected to the cover plate group 231 by means such as welding or bolting.

[0091] The two supporting beams 232 are disposed opposite to each other and contact the bottom guard plate 24 (as shown in FIG. 4A and FIG. 4B). In this case, the bottom guard plate 24, the cover plate group 231, and the two supporting beams 232 enclose the mounting cavity 22 having openings 21 at two ends, respectively.

[0092] For example, as shown in FIG. 5, FIG. 6A, and FIG. 6B, the two supporting beams 232 are located between the two sill beams 1, and two ends of each supporting beam 232 respectively contact the two sill beams 1. In this way, the two supporting beams 232 may support the two sill beams 1, so as to prevent the two sill beams 1 from deforming in a direction close to each other. In this way, a side pole crash performance of the vehicle may be improved, thereby improving a reliability of the vehicle.

[0093] In some embodiments, as shown in FIG. 7, FIG. 7 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 sealing members 4. The two sealing members 4 are connected to the cover plate group 231 and are located at two opposite ends of the cover plate group 231 in an arrangement direction of the two sill beams. Each sealing member 4 corresponds to a sill beam 1, and the sealing member 4 contacts a corresponding sill beam 1.

[0094] It can be understood that the sealing members 4 can seal a gap between the cover plate group 231 and the sill beam 1, thereby reducing a risk of water, dust, and other debris entering the mounting cavity 22. In this way, a risk of failure of the cell assembly 3 can be reduced, which is conducive to reducing a failure rate of the vehicle.

[0095] For example, the sill beam 1 includes a main body portion 11 and a sealing portion 12. The cover plate group 231 is located between the two main body portions 11 of the two sill beams 1. The sealing portion 12 is disposed on a side of the main body portion 11 close to the cover plate group 231 and connected to the main body portion 11. On this basis, the sealing member 4 abuts against a surface of the sealing portion 12 away from the bottom guard plate 24.

[0096] In this way, the sealing member 4 and the sealing portion 12 abutting against each other may seal the gap between the cover plate group 231 and the sill beam 1, thereby improving a reliability of sealing, which is conducive to further reducing the risk of water, dust, and other debris entering the mounting cavity 22, thereby reducing the failure rate of the vehicle.

[0097] It should be noted that the main body portion 11 and the sealing portion 12 may be integrally formed. In this way, a structural strength of the sill beam 1 can be improved, thereby improving the side pole crash performance of the vehicle, and thus improving the reliability of the vehicle.

[0098] The main body portion 11 may be a solid structure or a hollow structure, which may be selected according to an actual condition, and the present disclosure is not limited thereto.

[0099] In some embodiments, as shown in FIG. 7, the main body portion 11 is a hollow structure. In this way, it is conducive to reducing a weight of the complete vehicle, thereby reducing an energy consumption of the vehicle, and thus improving the cruising range of the vehicle. Moreover, the hollow structure can further buffer the crash, which is conducive to improving the reliability of the vehicle.

[0100] In this case, the main body portion 11 has an accommodating cavity 111. A number of accommodating cavities 111 may be one or more, which may be selected according to an actual condition, and the present disclosure is not limited thereto. For example, the main body portion 11 has a plurality of accommodating cavities 111.

[0101] It should be noted that the battery mounting structure 100 may further include an air conditioning pipe 5, and the air conditioning pipe 5 is disposed in the accommodating cavity 111. The air conditioning pipe 5 is used to transmit a refrigerant, so that an air conditioning system of the vehicle operates normally, thereby achieving cooling or heating of an interior space of the vehicle, thus improving a use effect of the vehicle.

[0102] It can be understood that disposing the air conditioning pipe 5 in the accommodating cavity 111 of the main body portion 11 can reduce an occupation of the air conditioning pipe 5 on the layout space of the cell assembly 3, which is conducive to further improving the space utilization rate of the lower body.

[0103] In some embodiments, as shown in FIG. 7, the sill beam 1 further includes a connecting portion 13. The connecting portion 13 is located on a side of the main body portion 11 close to the bottom guard plate 24 and connected to the main body portion 11. The connecting portion 13 may be integrally formed with the main body portion 11.

[0104] On this basis, an end portion of the bottom guard plate 24 close to the sill beam 1 is located on a side of the connecting portion 13 away from the main body portion 11, and the end portion of the bottom guard plate 24 close to the sill beam 1 is connected to the connecting portion 13. That is, the end portion of the bottom guard plate 24 close to the sill beam 1 is located on a lower side of the connecting portion 13 and connected to the connecting portion 13. The bottom guard plate 24 may be connected to the connecting portion 13 by means such as bolting, snap connection, or riveting.

[0105] Arranged in such manner, it is convenient to detach the bottom guard plate 24 from the sill beam 1, so as to repair or replace the cell assembly 3 in the mounting cavity 22.

[0106] For example, the bottom guard plate 24 includes a supporting portion 241, two recessed portions 242, and two mounting portions 243. Along an arrangement direction of the two sill beams 1, the supporting portion 241 is located between the two recessed portions 242, and the supporting portion 241 is connected to the two recessed portions 242. A recessed portion 242 is recessed toward a direction close to the cover body relative to the supporting portion 241, so as to provide a groove 2421. Along the arrangement direction of the two 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 a side of the connecting portion 13 away from the main body portion 11 and connected to the connecting portion 13. On this basis, the cell assembly 3 is disposed on the supporting portion 241.

[0107] It should be noted that the battery mounting structure 100 may further include a brake pipeline 6 and a wiring harness 7. The brake pipeline 6 is used to transmit a brake medium. For example, the brake pipeline 6 is used to transmit brake fluid. The wiring harness 7 is used to connect the cell assembly 3 and complete vehicle components, so as to achieve transmission of electrical energy and a data signal.

[0108] The brake pipeline 6 and the wiring harness 7 may be connected to the bottom guard plate 24, and the brake pipeline 6 and the wiring harness 7 may be disposed in the groove 2421. In this way, an occupation of the brake pipeline 6 and the wiring harness 7 on the layout space of the cell assembly 3 can be reduced, which is conducive to further improving the space utilization rate of the lower body.

[0109] In some embodiments, the battery mounting structure 100 further includes a bottom cold plate. The bottom cold plate is disposed in the mounting cavity 22 and located on a lower side of the cell assembly 3 (i.e., a side of the cell assembly 3 away from the mounting assembly 2). The bottom cold plate has a first cooling channel, where the first cooling channel is used to transmit a coolant. It should be noted that the first cooling channel may be connected to a vehicle coolant flow pipeline.

[0110] It can be understood that the coolant may flow in the first cooling channel, and then exchange heat with the cell assembly 3 through the bottom cold plate, so as to take away heat generated during an operation of the cell assembly 3. In this way, a heat dissipation efficiency of the cell assembly 3 can be improved, thereby reducing the risk of failure of the cell assembly 3.

[0111] For example, the bottom cold plate contacts the cell assembly 3. In this way, on one hand, the heat dissipation efficiency of the cell assembly 3 may be further improved, and on another hand, the bottom cold plate can provide support for the cell assembly 3, which is conducive to improving a stability of installation of the cell assembly 3.

[0112] In some embodiments, as shown in FIG. 6A and FIG. 6B, the battery mounting structure 100 further includes a seat cross member 8 (e.g., a seat cross beam). The seat cross member 8 is disposed on the mounting assembly 2 and located on an upper side of the mounting assembly 2 (i.e., a side of the mounting assembly 2 away from the bottom guard plate 24). It should be noted that the seat cross member 8 is used to mount a seat.

[0113] The seat cross member 8 may be disposed on the cover body 23. For example, the seat cross member 8 is disposed on the cover plate group 231 of the cover body 23.

[0114] It can be understood that the seat cross member 8 may improve a structural strength of the mounting assembly 2. In this way, the mounting assembly 2 can provide more reliable protection for the cell assembly 3, which is conducive to improving a reliability of the vehicle.

[0115] For example, the seat cross member 8 extends along the arrangement direction of the two sill beams 1 (as shown in FIG. 5). In this way, a difficulty of deformation of the mounting assembly 2 in the arrangement direction of the two sill beams 1 may be increased, thereby further improving the side pole crash performance of the vehicle, and thus improving the reliability of the vehicle.

[0116] It should be noted that, as shown in FIG. 8, FIG. 8 is an exploded view of a cover body 23 according to some embodiments of the present disclosure. The cover plate group 231 may include a floor 2311 and a top cold plate 2312. The floor 2311 is disposed opposite to the bottom guard plate 24 (as shown in FIG. 7), and the seat cross member 8 (as shown in FIG. 6A and FIG. 6B) is disposed on the floor 2311. The top cold plate 2312 is located between the floor 2311 and the bottom guard plate 24 and connected to the floor 2311.

[0117] In this case, the two supporting beams 232 are located on a side of the top cold plate 2312 away from the floor 2311 and connected to the top cold plate 2312.

[0118] The top cold plate 2312 has a second cooling channel, where the second cooling channel is used to transmit a coolant. It should be noted that the second cooling channel may be connected to a vehicle coolant flow pipeline.

[0119] It can be understood that the coolant may flow in the second cooling channel, and then exchange heat with the cell assembly 3 through the top cold plate 2312, so as to take away heat generated during the operation of the cell assembly 3. In this way, the heat dissipation efficiency of the cell assembly 3 can be further improved, thereby reducing the risk of failure of the cell assembly 3.

[0120] For example, as shown in FIG. 9, FIG. 9 is a structural diagram of a cell assembly 3, a strap 20, a fixing member 10, an explosion-proof beam 9, and a cover body 23 according to some embodiments of the present disclosure. The top cold plate 2312 contacts the cell assembly 3. In this way, the heat dissipation efficiency of the cell assembly 3 may be further improved.

[0121] It should be noted that the cover plate group 231 may also include the floor 2311 only. In this case, the floor 2311 is disposed opposite to the bottom guard plate 24. The two supporting beams 232 are located between the floor 2311 and the bottom guard plate 24 and are connected to the floor 2311. In this case, the bottom guard plate 24, the floor 2311, and the two supporting beams 232 enclose the mounting cavity 22.

[0122] It can be understood that, in a case where the cover plate group 231 includes the floor 2311, the two sealing members 4 may be connected to the floor 2311, and the two sealing members 4 are located at two opposite ends of the floor 2311 in the arrangement direction of the two sill beams 1. In this case, the sealing members 4 and the sealing portions 12 abutting against each other can seal a gap between the floor 2311 and the sill beam 1.

[0123] In some embodiments, as shown in FIG. 5, FIG. 6A, and FIG. 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 located in the mounting cavity 22.

[0124] 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 group 231 of the cover body 23.

[0125] It can be understood that the explosion-proof beam 9 may improve a structural strength of the cover body 23 of the mounting assembly 2. In this way, the cover body 23 of the mounting assembly 2 can provide more reliable protection for the cell assembly 3, which is conducive to improving the reliability of the vehicle.

[0126] For example, the explosion-proof beam 9 extends along the arrangement direction of the two sill beams 1, and two ends of each explosion-proof beam 9 respectively contact the two sill beams 1. In this way, the explosion-proof beam 9 can support the sill beams 1, so as to prevent the two sill beams 1 from deforming in a direction close to each other, thereby further improving the side pole crash performance of the vehicle and improving the reliability of the vehicle.

[0127] A number of explosion-proof beams 9 may be one or more, which may be selected according to an actual condition, and the present disclosure is not limited thereto. For example, the battery mounting structure 100 includes a plurality of explosion-proof beams 9, and the plurality of explosion-proof beams 9 are arranged at an interval along an extending direction of the sill beam 1 (e.g., a front-rear direction). The extending direction of the sill beam 1 is perpendicular to the arrangement direction of the two sill beams 1.

[0128] It can be understood that the plurality of explosion-proof beams 9 can further improve the structural strength of the cover body 23, thereby providing more reliable protection for the cell assembly 3.

[0129] In a case where the battery mounting structure 100 includes a plurality of explosion-proof beams 9, as shown in FIG. 9, the cell assembly 3 may include a first component 32. The first component 32 is disposed between each group of two adjacent explosion-proof beams 9, and two ends of the first component 32 in the extending direction of the sill beam 1 respectively contact the two adjacent explosion-proof beams 9.

[0130] It can be understood that the first component 32 includes a plurality of cells 31. For example, the plurality of cells 31 of the first component 32 are arranged in a rectangular array in a horizontal direction, and two adjacent cells 31 in the first component 32 contact each other.

[0131] Arranged in such manner, the explosion-proof beams 9 may further restrict expansion of cells 31 in the first component 32, thereby reducing a risk of damage to the cells 31 in the first component 32, and thus improving the reliability of the vehicle.

[0132] In addition, the cell assembly 3 may further include a second component 33. The second component 33 is disposed between at least one supporting beam 232 and an explosion-proof beam 9 adjacent to the at least one supporting beam 232, the second component 33 contacts the adjacent explosion-proof beam 9, and the second component 33 contacts the adjacent supporting beam 232.

[0133] It can be understood that the second component 33 includes a plurality of cells 31. For example, the plurality of cells 31 of the second component 33 are arranged in a rectangular array in the horizontal direction, and two adjacent cells 31 in the second component 33 contact each other.

[0134] Arranged in such manner, the supporting beams 232 and the explosion-proof beams 9 may further restrict expansion of cells 31 in the second component 33, thereby reducing a risk of damage to the cells 31 in the second component 33, and thus improving the reliability of the vehicle.

[0135] In some embodiments, as shown in FIG. 6A and FIG. 6B, the at least one explosion-proof beam 9 includes a fixed beam 91. The seat cross member 8 is disposed on the cover body 23 at a position opposite to the fixed beam 91, and the seat cross member 8 and the explosion-proof beam 9 extend along the arrangement direction of the two sill beams 1 (as shown in FIG. 5).

[0136] That is to say, as shown in FIG. 10A and FIG. 10B, FIG. 10A is an enlarged view of the battery mounting structure 100 at the fixed beam 91 according to some embodiments of the present disclosure, and FIG. 10B is an enlarged view of the battery mounting structure 100 at the fixed beam 91 from another perspective according to some embodiments of the present disclosure. The seat cross member 8 and the fixed beam 91 are located on two opposite sides of the cover body 23, and the seat cross member 8 and the fixed beam 91 are opposite in position. In this way, the seat cross member 8 and the fixed beam 91 can mutually reinforce each other. Thus, on one hand, a more stable support can be provided for the seat, and on another hand, the side pole crash performance of the vehicle can be further improved, thereby improving the reliability of the vehicle.

[0137] 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 fixed beam 91.

[0138] The fixing member 10 may be used to fix the cell assembly 3. For example, the fixing member 10 may be connected to the cell assembly 3 by means such as screw connection or snap connection to achieve fixing of the cell assembly 3.

[0139] It can be understood that the fixing member 10 can improve the reliability of installation of the cell assembly 3.

[0140] In some embodiments, as shown in FIG. 9, the battery mounting structure 100 further includes a strap 20. The strap 20 is disposed in the mounting cavity 22 and connected to the cover body 23. The strap 20 and the cover body 23 enclose a fixing space, and the cell assembly 3 is located in the fixing space.

[0141] As shown in FIG. 4A and FIG. 4B, along an arrangement direction of the cover body 23 and the bottom guard plate 24, the cell assembly 3 has a first end and a second end that are opposite to each other. The first end abuts against the cover body 23, and the second end abuts against the strap 20.

[0142] Arranged in such manner, the strap 20 can restrict the cell assembly 3 from moving in a direction away from the cover body 23, thereby further improving the reliability of installation of the cell assembly 3.

[0143] For example, as shown in FIG. 9, there are a plurality of straps 20, each row of cells 31 of each first component 32 corresponds to a strap 20 and abuts against a corresponding strap 20. Similarly, each row of cells 31 of each second component 33 corresponds to a strap 20 and abuts against a corresponding strap 20.

[0144] It should be noted that the strap 20 may be connected to the explosion-proof beam 9, or the strap 20 may be connected to the supporting beam 232, or the strap 20 may be connected to the cover plate group 231, which may be selected according to an actual condition, and the present disclosure is not limited thereto.

[0145] 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 battery mounting structure.

[0146] The above are merely specific embodiments of the present disclosure, however, the protection scope of the present disclosure is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present disclosure should be covered by the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claims.
