Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a vehicle body and a vehicle. Background Technology

[0002] A vehicle is a means of transportation that can be used to carry people and goods. A vehicle consists of a body and a rear subframe. The body can be enclosed to form a space for carrying people and goods. The rear subframe is installed under the body and located at the rear of the body. The rear subframe can be used to support and install components such as the rear suspension system.

[0003] In related technologies, it is relatively difficult to install drive units (such as engines, motors, etc.) on the rear subframe. Utility Model Content

[0004] This application provides a vehicle body and a vehicle to solve the problem of difficulty in installing a drive unit on the rear subframe in the aforementioned related technologies.

[0005] This application provides a vehicle body including a rear floor, a support structure, and a partition. The rear floor has a clearance opening. The partition is disposed above the clearance opening via the support structure, and a clearance space is formed between the partition and the clearance opening. The clearance opening connects the clearance space to the outside of the vehicle body. The clearance opening and the clearance space are used to avoid the drive mechanism of the vehicle, and the partition is used to isolate the clearance space from the interior space of the vehicle body.

[0006] The vehicle body provided in this application embodiment, by providing a clearance opening and clearance space, ensures that the rear floor and body do not obstruct the installation of the drive unit on the rear subframe. This solves the problem of insufficient space for drive unit installation on the rear subframe, making drive unit installation on the rear subframe easier. Furthermore, the partition isolates the vehicle body from external noise, dust, water, etc., minimizing the impact of the clearance opening and clearance space on the vehicle's internal sealing and NVH performance. This results in better sealing and NVH performance for vehicles with drive units mounted on the rear subframe. Additionally, the support structure allows the partition to be stably positioned above the clearance opening, reducing the risk of breakage and further contributing to maintaining the sealing and NVH performance of vehicles with drive units mounted on the rear subframe.

[0007] In addition, the vehicle body provided in this application embodiment can be modified based on the existing vehicle body of a model with a low rear floor height. It is relatively easy to modify the existing vehicle body of a model with a low rear floor height into a model that requires the installation of a drive unit on the rear subframe, and the technical modification cost is low.

[0008] In one possible implementation, the lower end of the support structure is connected to the rear floor and surrounds the clearance opening; the support structure and partition are used to enclose and form the clearance space.

[0009] In this way, the support structure surrounds the clearance opening, facilitating a stable connection between the support structure and the rear floor. Furthermore, the support structure has a large support surface for the partition, which helps to provide stable support for the partition. Additionally, the support structure also facilitates the isolation of the clearance space from the vehicle's interior space.

[0010] In one possible implementation, the lower end of the support structure overlaps the rear floor, and the lower end of the support structure is fixed and sealed to the rear floor. The partition overlaps the upper end of the support structure, and the partition is fixed and sealed to the upper end of the support structure. The support structure is used to isolate the clearance space from the interior space of the vehicle body.

[0011] In this way, in addition to supporting the partition, the support structure can also isolate the clearance space from the interior space of the vehicle body. Noise, dust, water and other substances are not easily able to enter the interior space of the vehicle body through the clearance space, which makes the vehicle with the drive unit mounted on the rear subframe have better sealing and NVH performance.

[0012] In one possible implementation, the support structure includes a support beam, the lower side of which is connected to the rear floor, and the upper side of which is connected to a partition. The vehicle body also includes a left longitudinal beam and a right longitudinal beam, which are located on the left and right sides of the vehicle body, respectively, and the left and right ends of the support beam are fixedly connected to the left and right longitudinal beams, respectively.

[0013] In this way, the supporting beam can not only support the partition, but also improve the overall rigidity and strength of the vehicle body. This helps to reduce the impact of opening the clearance opening in the rear floor on the overall rigidity and strength of the vehicle body, and allows the vehicle body with the clearance opening in the rear floor to have better rigidity and strength.

[0014] In one possible implementation, a left connector is provided between the left end of the support beam and the left longitudinal beam. The left connector includes a first connecting portion and a second connecting portion that is bent relative to the first connecting portion. The first connecting portion is fixedly connected to the support beam, and the second connecting portion is fixedly connected to the left longitudinal beam, so that the left end of the support beam is fixedly connected to the left longitudinal beam through the left connector.

[0015] In this way, the connection between the supporting crossbeam and the left longitudinal beam is relatively convenient.

[0016] In one possible implementation, a right connector is provided between the right end of the support beam and the right longitudinal beam. The right connector includes a third connecting part and a fourth connecting part that is bent relative to the third connecting part. The third connecting part is fixedly connected to the support beam, and the fourth connecting part is fixedly connected to the right longitudinal beam, so that the right end of the support beam is fixedly connected to the right longitudinal beam through the right connector.

[0017] This makes it easier to connect the support beam to the right longitudinal beam.

[0018] In one possible implementation, the vehicle body also includes a first crossbeam. The left and right ends of the first crossbeam are fixedly connected to the left longitudinal beam and the right longitudinal beam, respectively, and the supporting crossbeam is fixedly connected to the first crossbeam.

[0019] This can improve the overall rigidity and strength of the vehicle body, reduce the impact of opening a clearance opening in the rear floor on the overall rigidity and strength of the vehicle body, and enable the vehicle body with a clearance opening in the rear floor to have better rigidity and strength.

[0020] In one possible implementation, the support beam has a first connecting hole, the first beam has a second connecting hole opposite to the first connecting hole, and the support beam is fixedly connected to the first beam by fasteners passing through the first connecting hole and the second connecting hole.

[0021] In this way, it is relatively easy to fix the support beam to the first beam.

[0022] In one possible implementation, the support beam includes a first sidewall and a second sidewall disposed opposite to each other. A connecting hole is located in the first sidewall, which is fixedly connected to the first beam. The second sidewall has a mounting opening opposite the first connecting hole, for a tool for installing or removing fasteners to pass through.

[0023] This facilitates the assembly and disassembly of the supporting beam and the first beam.

[0024] In one possible implementation, the first crossbeam is located below the rear floor. The rear floor has a third connecting hole opposite the first connecting hole, and fasteners pass through the first, second, and third connecting holes, securing the support crossbeam, the rear floor, and the first crossbeam together.

[0025] In this way, the first crossbeam does not occupy the space above the rear floor, which helps to increase the space inside the vehicle for carrying passengers and cargo. In addition, the fasteners passing through the first, second, and third connecting holes facilitate the connection of the rear floor and the supporting crossbeams and the first crossbeam located above and below the rear floor.

[0026] In one possible implementation, the support structure also includes a support plate structure. The support plate structure is positioned in front of and behind the support beam, connected to the support beam, with its lower end connected to the rear floor and its upper end connected to a partition. The support plate structure, support beam, and partition are used to enclose and form a clearance space.

[0027] This facilitates stable support for the partition. Furthermore, the support structure helps isolate the clearance space from the vehicle's interior, preventing noise, dust, and water from entering the interior through the clearance space.

[0028] In one possible implementation, one end of the support plate structure is connected to the support beam and overlaps the support beam, with the support plate structure and the support beam being fixed and sealed together.

[0029] This helps prevent noise, dust, water, and other external factors from entering the vehicle's interior, thus improving the vehicle's sealing and NVH performance.

[0030] In one possible implementation, the end of the support plate structure connected to the support beam has a first flange structure, and the support plate structure is connected to the support beam through the first flange structure.

[0031] In this way, the connection surface between the support plate structure and the support beam is relatively large, which facilitates the fixing and sealing connection between the support plate structure and the support beam.

[0032] In one possible implementation, the lower end of the support plate structure has a second flange structure, through which the support plate structure is connected to the rear floor.

[0033] This results in a larger connection surface between the support plate structure and the rear floor, facilitating the fixing and sealing of the support plate structure and the rear floor.

[0034] In one possible implementation, the upper end of the support plate structure has a third flange structure, through which the support plate structure is connected to the partition.

[0035] This results in a larger connection surface between the support plate structure and the partition, facilitating the fixing and sealing of the support plate structure and the partition.

[0036] In one possible implementation, the support plate structure includes a first support plate, a second support plate, and a third support plate. The first and second support plates are arranged opposite each other, and the third support plate and the support beam are located on the front and rear sides of the first and second support plates, respectively. The front and rear ends of the first support plate are connected to the third support plate and the support beam, respectively, and the front and rear ends of the second support plate are also connected to the third support plate and the support beam, respectively. The lower ends of the first, second, and third support plates are all connected to the rear floor, and the upper ends of the first, second, and third support plates are all connected to a partition. The first, second, and third support plates, the support beam, and the partition are used to enclose and form a clearance space.

[0037] This makes it easier to form the support plate structure, and the assembly of the support structure with the rear floor and partition is also more convenient.

[0038] In one possible implementation, the third support plate overlaps the end of the first support plate away from the support beam and the end of the second support plate away from the support beam. The third support plate is fixed and sealed to the first support plate, and the third support plate is fixed and sealed to the second support plate.

[0039] This helps prevent noise, dust, water, and other external factors from entering the vehicle's interior, thus improving the vehicle's sealing and NVH performance.

[0040] In one possible implementation, the end of the first support plate that connects to the third support plate has a fourth flange structure, and the first support plate is connected to the third support plate through the fourth flange structure.

[0041] In this way, the connection surface between the first support plate and the third support plate is relatively large, which facilitates the fixing and sealing connection between the first support plate and the third support plate.

[0042] In one possible implementation, the end of the second support plate that connects to the third support plate has a fifth flange structure, and the second support plate is connected to the third support plate through the fifth flange structure.

[0043] In this way, the connection surface between the second support plate and the third support plate is relatively large, which facilitates the fixing and sealing connection between the second support plate and the third support plate.

[0044] In one possible implementation, the support plate structure includes a first structural portion and a second structural portion. The lower end of the first structural portion is connected to the rear floor, and the second structural portion is located above the first structural portion. The upper end of the second structural portion is connected to a partition. Both the first and second structural portions are connected to a support beam. The end of the first structural portion away from the support beam protrudes from the second structural portion, and the clearance portion is located below the portion of the first structural portion that protrudes from the second structural portion.

[0045] In this way, for a drive unit with a larger lower dimension and a smaller upper dimension, the area enclosed by the first structural section can avoid the larger lower part of the drive unit, and the area enclosed by the second structural section can avoid the smaller upper part of the drive unit. This minimizes the clearance space and facilitates the arrangement of components on the vehicle body. Furthermore, the larger lower dimension and smaller upper dimension of the support structure make the support structure more stable, which is beneficial for providing stable support for the partition. Additionally, it also facilitates avoiding obstacles to components within the vehicle body.

[0046] In one possible implementation, the side of the second structural part away from the supporting beam is an inclined structure relative to the rear floor, and the upper end of the side of the second structural part away from the supporting beam is biased towards the supporting beam relative to the lower end of the side of the second structural part away from the supporting beam.

[0047] This sloping design improves the stability of the support structure, thereby enhancing the stability of the bulkhead support. Furthermore, it facilitates obstacle avoidance of components within the vehicle body.

[0048] In one possible implementation, the vehicle body includes a second crossbeam. The second crossbeam is spaced above the rear floor, creating a gap between the second crossbeam and the rear floor, with a clearance portion located below the second crossbeam. At least a portion of a second structural member is located between the second crossbeam and a supporting crossbeam, and a first structural member passes through the gap, such that a portion of the clearance space is located within the gap, and the portion of the clearance space within the gap communicates with the portion of the clearance opening located below the second crossbeam.

[0049] In this way, the space between the second crossbeam and the rear floor can be used to avoid the drive unit, resulting in high space utilization and facilitating the compact arrangement of body parts.

[0050] In one possible implementation, the vehicle body includes a left longitudinal beam and a right longitudinal beam, which are located on the left and right sides of the vehicle body, respectively. The left and right ends of the partition are fixedly connected to the left and right longitudinal beams, respectively.

[0051] In this way, the left and right longitudinal beams can support the partition, making the partition assembly more stable. In addition, after the partition is fixedly connected to the left and right longitudinal beams, it can also improve the overall rigidity and strength of the vehicle body, which helps to reduce the impact of the rear floor clearance opening on the overall rigidity and strength of the vehicle body, so that the vehicle body with the rear floor clearance opening has better rigidity and strength.

[0052] In one possible implementation, the left end of the partition overlaps the left longitudinal beam, and the left end of the partition is sealed to the left longitudinal beam; the right end of the partition overlaps the right longitudinal beam, and the right end of the partition is sealed to the right longitudinal beam.

[0053] This helps prevent noise, dust, water, and other external factors from entering the vehicle's interior, thus improving the vehicle's sealing and NVH performance.

[0054] In one possible implementation, the left end of the partition has a sixth flange structure, which connects the left end of the partition to the left longitudinal beam.

[0055] This results in a larger connection surface between the partition and the left longitudinal beam, facilitating the fixing and sealing of the partition and the left longitudinal beam.

[0056] In one possible implementation, the right end of the partition has a seventh flange structure, which connects the right end of the partition to the right longitudinal beam.

[0057] This results in a larger connection surface between the partition and the right longitudinal beam, facilitating the fixing and sealing of the partition and the right longitudinal beam.

[0058] In one possible implementation, the vehicle body includes a second crossbeam. The second crossbeam is positioned above the rear floor, and is positioned anteriorly and posteriorly with a partition, which is fixedly connected to the second crossbeam.

[0059] In this way, the second crossbeam can support the partition, making the partition assembly more stable. In addition, after the partition is fixedly connected to the second crossbeam, it can also improve the overall rigidity and strength of the vehicle body, which helps to reduce the impact of the rear floor clearance opening on the overall rigidity and strength of the vehicle body, so that the vehicle body with the rear floor clearance opening has better rigidity and strength.

[0060] In one possible implementation, one end of the partition connects to the second crossbeam, overlapping the second crossbeam, and the partition and the second crossbeam are sealed together.

[0061] This helps prevent noise, dust, water, and other external factors from entering the vehicle's interior, thus improving the vehicle's sealing and NVH performance.

[0062] In one possible implementation, the end of the partition connected to the second crossbeam has an eighth flange structure, through which the partition is connected to the second crossbeam.

[0063] In this way, the connection surface between the partition and the second crossbeam is larger, which facilitates the fixing and sealing connection between the partition and the second crossbeam.

[0064] A second aspect of this application provides a vehicle including a rear subframe, a drive unit, and the vehicle body as described in any of the above embodiments. The rear subframe is disposed below the rear floor of the vehicle body, and the drive unit is disposed on the rear subframe and at a clearance opening in the vehicle body, with at least a portion of the drive unit located within the clearance space formed by the vehicle body.

[0082] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0083] This application provides a vehicle, which may include, but is not limited to, a gasoline-powered vehicle, a hybrid vehicle, a pure electric vehicle, a range-extended electric vehicle, and a plug-in hybrid vehicle.

[0084] In this embodiment of the application, the vehicle includes a body, which can be configured to form an internal space for carrying people and goods. In other words, the body has an internal space for carrying people and goods.

[0085] Figure 1 This is a schematic diagram of a vehicle body provided in an embodiment of this application. In the diagram, x points forward, y points to the right, and z points upward.

[0086] When a vehicle is parked on the ground, the front is the direction from the rear of the vehicle to the front, the back is the direction from the front of the vehicle to the rear, the top is the direction from the ground to the roof, the bottom is the direction from the roof to the ground, the left is the direction from the right hand position of a person standing facing the front of the vehicle and with their back to the rear of the vehicle to the left hand position, and the right is the direction from the left hand position of a person standing facing the front of the vehicle and with their back to the rear of the vehicle to the right hand position.

[0087] The front-to-back direction of a vehicle can also be called the length direction of the vehicle; the left-to-right direction of a vehicle can also be called the width direction of the vehicle; and the up-and-down direction of a vehicle can also be called the height direction of the vehicle.

[0088] like Figure 1 As shown, the vehicle body includes a left longitudinal beam 510 and a right longitudinal beam 520, which are located on the left and right sides of the vehicle body, respectively. The left longitudinal beam 510 and the right longitudinal beam 520 are used to form the frame structure of the vehicle body.

[0089] In this embodiment, a longitudinal beam refers to a beam extending in the front-to-back direction at both ends; that is, a longitudinal beam refers to a beam extending in the length direction of the vehicle at both ends. A crossbeam refers to a beam extending in the left-to-right direction at both ends; that is, a crossbeam refers to a beam extending in the width direction of the vehicle at both ends. In addition to the left longitudinal beam 510 and the right longitudinal beam 520, the vehicle body also includes multiple crossbeams whose ends are fixedly connected to the left longitudinal beam 510 and the right longitudinal beam 520, respectively. The left longitudinal beam 510, the right longitudinal beam 520, and the multiple crossbeams connecting the left longitudinal beam 510 and the right longitudinal beam 520 all serve to form the frame structure of the vehicle body.

[0090] The vehicle body also includes a rear floor 100, which is located at the rear of the vehicle body and is fixedly connected to the vehicle body's frame structure.

[0091] For example, the left and right ends of the rear floor 100 are fixedly connected to the left longitudinal beam 510 and the right longitudinal beam 520, respectively. For instance, the left end of the rear floor 100 may overlap the left longitudinal beam 510, and the left end of the rear floor 100 is fixedly and sealed to the left longitudinal beam 510. The right end of the rear floor 100 may overlap the right longitudinal beam 520, and the right end of the rear floor 100 is fixedly and sealed to the right longitudinal beam 520.

[0092] The vehicle also includes a rear subframe (not shown), which is located at the rear of the vehicle and is positioned below the rear floor 100. The rear subframe can be used to support and mount components such as the rear suspension system.

[0093] The vehicle also includes a drive unit (not shown) for providing power for the vehicle's movement. For example, the drive unit may include, but is not limited to, an engine, an electric motor, etc.

[0094] In related technologies, the rear floor is often low, resulting in limited space underneath. When the drive unit needs to be mounted on the rear subframe, the rear floor obstructs the installation, leading to insufficient space for installation. Converting existing vehicles with low rear floor heights (e.g., front-wheel-drive gasoline vehicles) to vehicles requiring drive unit mounting on the rear subframe (e.g., four-wheel-drive vehicles, hybrid vehicles, electric vehicles) presents significant challenges.

[0095] Figure 2 This is a schematic diagram of another vehicle body provided as an embodiment of this application. Figure 3 This is a schematic diagram of another vehicle body provided in an embodiment of this application.

[0096] like Figures 1-3 As shown, based on this, in this embodiment of the application, the vehicle body further includes a support structure 200 and a partition 300. The rear floor 100 has a clearance opening 110. The partition 300 is disposed above the clearance opening 110 via the support structure 200, forming a clearance space between the partition 300 and the clearance opening 110. The clearance opening 110 connects the clearance space with the outside of the vehicle body. The drive unit is disposed on the rear subframe and located at the clearance opening 110 of the vehicle body. The clearance opening 110 and the clearance space are used to avoid the vehicle's drive unit. At least a portion of the drive unit is located within the clearance space formed by the vehicle body. The partition 300 is used to isolate the clearance space from the interior space of the vehicle body. The interior space of the vehicle body refers to the space within the vehicle body for carrying people and goods.

[0097] In this way, by setting up the clearance opening 110 and clearance space, the rear floor 100 and the vehicle body will not obstruct the installation of the drive unit on the rear subframe, solving the problem of insufficient space for drive unit installation on the rear subframe, making drive unit installation on the rear subframe easier. Furthermore, through the isolation provided by the partition 300, external noise, dust, water, etc., are less likely to enter the vehicle's interior space, minimizing the impact of the clearance opening 110 and clearance space on the vehicle's interior sealing and NVH performance, resulting in better sealing and NVH performance for vehicles with drive units mounted on the rear subframe. Additionally, the support structure 200 allows the partition 300 to be stably positioned above the clearance opening 110, reducing the risk of breakage and further contributing to maintaining the sealing and NVH performance of vehicles with drive units mounted on the rear subframe.

[0098] In addition, the vehicle body provided in this application embodiment can be modified based on the existing vehicle body of a model with a low rear floor 100 height. It is relatively easy to modify the existing vehicle body of a model with a low rear floor 100 height into a model that requires the installation of a drive unit on the rear subframe, and the technical modification cost is low.

[0099] When modifying a vehicle body based on an existing model with a low rear floor height, the rear floor 100 of the existing model with a low rear floor height can be partially removed to form the rear floor 100 with a clearance opening 110 as described in this application. Then, a support structure 200 and a partition 300 are installed on the rear floor 100 with the clearance opening 110 to form the vehicle body with the clearance opening 110, clearance space, support structure 200, and partition 300 as described in this application.

[0100] In some possible implementations, the lower end of the support structure 200 is connected to the rear floor 100 and surrounds the clearance opening 110. The support structure 200 and the partition 300 are used to enclose and form a clearance space.

[0101] In this way, the support structure 200 surrounds the clearance opening 110, facilitating a stable connection between the support structure 200 and the rear floor 100. Furthermore, the support structure 200 provides a large support surface for the partition 300, which is beneficial for the stable support of the partition 300 by the support structure 200. Additionally, the support structure 200 also facilitates the isolation of the clearance space from the interior space of the vehicle body.

[0102] In some examples, the support structure 200 can form a clearance space by itself and the partition 300.

[0103] In another example, the support structure 200 may also be arranged together with other structures on the rear floor 100 (e.g., beams, longitudinal beams, etc.) and the partition 300 to form a clearance space.

[0104] In some possible implementations, the lower end of the support structure 200 overlaps with the rear floor 100, and the lower end of the support structure 200 is fixed and sealed to the rear floor 100. The partition 300 overlaps with the upper end of the support structure 200, and the partition 300 is fixed and sealed to the upper end of the support structure 200. The support structure 200 is used to isolate the clearance space from the interior space of the vehicle body.

[0105] In this way, the support structure 200 can not only support the partition 300, but also isolate the clearance space from the interior space of the vehicle body. Noise, dust, water and other substances are not easy to enter the interior space of the vehicle body through the clearance space, so that the vehicle with the drive unit installed on the rear subframe has better sealing and NVH performance.

[0106] For example, the support structure 200 can be connected to the rear floor 100 by means of welding, fastener connection or other methods.

[0107] For example, the support structure 200 can be connected to the partition 300 by welding, fastener connection or other means.

[0108] For example, the support structure 200 and the rear floor 100 can be bonded together by structural adhesive provided between them.

[0109] In some examples, the support structure 200 and the rear floor 100 can be sealed with a sealant placed between them.

[0110] In some examples, the support structure 200 and the rear floor 100 can be sealed by a seal (e.g., a gasket) placed between them.

[0111] For example, the support structure 200 and the partition 300 can be bonded together by structural adhesive provided between them.

[0112] In some examples, the support structure 200 and the partition 300 can be sealed with a sealant placed between them.

[0113] In some examples, the support structure 200 and the partition 300 can be sealed by a seal (e.g., a gasket) disposed between them.

[0114] In other possible implementations, the support structure 200 may include a plurality of spaced-apart support members, and the partition 300 is connected to the rear floor 100 through the spaced-apart support members. For example, the support members may be support columns, in which case the clearance space may be formed by the partition 300 and other structures on the rear floor 100 (e.g., beams, longitudinal beams, etc.).

[0115] like Figure 3As shown, in some possible embodiments, the left and right ends of the partition 300 are fixedly connected to the left longitudinal beam 510 and the right longitudinal beam 520, respectively.

[0116] In this way, the left longitudinal beam 510 and the right longitudinal beam 520 can support the partition 300, making the assembly of the partition 300 more stable. In addition, after the partition 300 is fixedly connected to the left longitudinal beam 510 and the right longitudinal beam 520, it can also improve the overall rigidity and strength of the vehicle body, which helps to reduce the impact of the clearance opening 110 in the rear floor 100 on the overall rigidity and strength of the vehicle body, so that the vehicle body with the clearance opening 110 in the rear floor 100 has better rigidity and strength.

[0117] For example, the partition 300 can be connected to the left longitudinal beam 510 by welding, fastener connection, or other means. For instance, the partition 300 can be connected to the left longitudinal beam 510 by spot welding or pull-riveting.

[0118] For example, the partition 300 can be connected to the right longitudinal beam 520 by welding, fastener connection, or other means. For instance, the partition 300 can be connected to the right longitudinal beam 520 by spot welding or pull-riveting.

[0119] In some possible implementations, the left end of the partition 300 overlaps with the left longitudinal beam 510, and the left end of the partition 300 is sealed to the left longitudinal beam 510; the right end of the partition 300 overlaps with the right longitudinal beam 520, and the right end of the partition 300 is sealed to the right longitudinal beam 520.

[0120] This helps prevent noise, dust, water, and other external factors from entering the vehicle's interior, thus improving the vehicle's sealing and NVH performance.

[0121] For example, the partition 300 and the left longitudinal beam 510 can be bonded together with structural adhesive provided between them.

[0122] In some examples, the partition 300 and the left longitudinal beam 510 can be sealed with a sealant placed between them.

[0123] In some examples, the partition 300 and the left longitudinal beam 510 can be sealed by a seal (e.g., a gasket) placed between them.

[0124] For example, the partition 300 and the right longitudinal beam 520 can be bonded together by structural adhesive applied between them.

[0125] In some examples, the partition 300 and the right longitudinal beam 520 can be sealed with a sealant placed between them.

[0126] In some examples, the partition 300 and the right longitudinal beam 520 can be sealed by a seal (e.g., a gasket) placed between them.

[0127] like Figure 3 As shown, in some possible embodiments, the vehicle body also includes a second crossbeam 800, which can be used to form the frame structure of the vehicle body. The second crossbeam 800 is disposed above the rear floor 100, and the second crossbeam 800 and the partition 300 are arranged front and rear, with the partition 300 and the second crossbeam 800 fixedly connected.

[0128] In this way, the second crossbeam 800 can support the partition 300, making the assembly of the partition 300 more stable. In addition, after the partition 300 is fixedly connected to the second crossbeam 800, it can also improve the overall rigidity and strength of the vehicle body, which helps to reduce the impact of the clearance opening 110 in the rear floor 100 on the overall rigidity and strength of the vehicle body, so that the vehicle body with the clearance opening 110 in the rear floor 100 has better rigidity and strength.

[0129] For example, the left and right ends of the second crossbeam 800 are fixedly connected to the left longitudinal beam 510 and the right longitudinal beam 520, respectively.

[0130] For example, the partition 300 can be connected to the second crossbeam 800 by welding, fastener connection, or other means. For instance, the partition 300 can be connected to the second crossbeam 800 by spot welding or blind riveting.

[0131] In some examples, the second crossbeam 800 may be located in front of the partition 300, with the front end of the partition 300 connected to the second crossbeam 800.

[0132] For example, the second crossbeam 800 can be used to install a seat; that is, the second crossbeam 800 can be a crossbeam used to install a seat.

[0133] In some possible implementations, one end of the partition 300 that connects to the second crossbeam 800 overlaps the second crossbeam 800, and the partition 300 and the second crossbeam 800 are sealed together.

[0134] This helps prevent noise, dust, water, and other external factors from entering the vehicle's interior, thus improving the vehicle's sealing and NVH performance.

[0135] For example, the partition 300 and the second crossbeam 800 can be bonded together by structural adhesive provided between them.

[0136] In some examples, the partition 300 and the second crossbeam 800 can be sealed with a sealant placed between them.

[0137] In some examples, the partition 300 and the second crossbeam 800 can be sealed by a seal (e.g., a gasket) placed between them.

[0138] In some possible implementations, the support structure 200 includes a support beam 210, the lower side of which is connected to the rear floor 100, and the upper side of which is connected to the partition 300. The left and right ends of the support beam 210 are fixedly connected to the left longitudinal beam 510 and the right longitudinal beam 520, respectively.

[0139] In this way, the supporting beam 210 can not only support the partition 300, but also improve the overall rigidity and strength of the vehicle body. This helps to reduce the impact of the clearance opening 110 on the overall rigidity and strength of the vehicle body, and allows the vehicle body with the clearance opening 110 in the rear floor 100 to have better rigidity and strength.

[0140] For example, the support beam 210 can be located in front of the clearance opening 110 or behind the clearance opening 110. For instance, when the second beam 800 is in front of the partition 300, the support beam 210 is located behind the clearance opening 110, and the rear end of the partition 300 is connected to the upper side of the support beam 210.

[0141] For example, the lower side of the support beam 210 is fixed and sealed to the rear floor 100, and the upper side of the support beam 210 is fixed and sealed to the partition 300.

[0142] For example, the support beam 210 can be connected to the rear floor 100 by welding, fastener connection, or other means. For instance, the support beam 210 can be connected to the rear floor 100 by fasteners.

[0143] In some examples, the support beam 210 and the rear floor 100 can be sealed with sealant placed between them.

[0144] In some examples, the support beam 210 and the rear floor 100 can be sealed by a seal (e.g., a gasket) placed between them.

[0145] For example, the support beam 210 can be connected to the partition 300 by welding, fastener connection, or other means. For instance, the support beam 210 can be connected to the partition 300 by MIG welding.

[0146] In some examples, the support beam 210 and the partition 300 can be sealed with a sealant placed between them.

[0147] In some examples, the support beam 210 and the partition 300 can be sealed by a seal (e.g., a gasket) placed between them.

[0148] Figure 4 An exploded view of a partition and support structure provided in an embodiment of this application.

[0149] In some possible implementations, a left connector 610 is provided between the left end of the support beam 210 and the left longitudinal beam 510. The left connector 610 includes a first connecting portion 611 and a second connecting portion 612 bent relative to the first connecting portion 611. The first connecting portion 611 is fixedly connected to the support beam 210, and the second connecting portion 612 is fixedly connected to the left longitudinal beam 510, so that the left end of the support beam 210 is fixedly connected to the left longitudinal beam 510 through the left connector 610.

[0150] In this way, it is easier to connect the support beam 210 with the left longitudinal beam 510.

[0151] For example, the left connector 610 can be a bent plate-like structure. For instance, the left connector 610 can be a plate-like structure bent into an "L" shape.

[0152] For example, the included angle between the first connecting part 611 and the second connecting part 612 can be a right angle, an obtuse angle, or an acute angle. The included angle between the first connecting part 611 and the second connecting part 612 is determined according to the relative position of the surface of the supporting beam 210 that connects to the first connecting part 611 and the surface of the left longitudinal beam 510 that connects to the second connecting part 612.

[0153] For example, the first connecting part 611 can be connected to the support beam 210 by welding, fastener connection, or other means. For instance, the first connecting part 611 can be connected to the support beam 210 by welding or blind riveting.

[0154] For example, the second connecting part 612 can be connected to the left longitudinal beam 510 by welding, fastener connection, or other means. For instance, the second connecting part 612 can be connected to the left longitudinal beam 510 by welding or blind riveting.

[0155] In some possible implementations, a right connector 620 is provided between the right end of the support beam 210 and the right longitudinal beam 520. The right connector 620 includes a third connecting portion and a fourth connecting portion that is bent relative to the third connecting portion. The third connecting portion is fixedly connected to the support beam 210, and the fourth connecting portion is fixedly connected to the right longitudinal beam 520, so that the right end of the support beam 210 is fixedly connected to the right longitudinal beam 520 through the right connector 620.

[0156] In this way, it is easier to connect the support beam 210 with the right longitudinal beam 520.

[0157] For example, the right connector 620 can be a bent plate-like structure. For instance, the right connector 620 can be a plate-like structure bent into an "L" shape.

[0158] For example, the included angle between the third connecting part and the fourth connecting part can be a right angle, an obtuse angle, or an acute angle. The included angle between the third connecting part and the fourth connecting part is determined according to the relative position of the surface of the supporting beam 210 that connects to the third connecting part and the surface of the right longitudinal beam 520 that connects to the fourth connecting part.

[0159] For example, the third connecting part can be connected to the support beam 210 by welding, fastener connection, or other means. For instance, the third connecting part can be connected to the support beam 210 by welding or blind riveting.

[0160] For example, the fourth connecting part can be connected to the right longitudinal beam 520 by welding, fastener connection, or other means. For instance, the fourth connecting part can be connected to the right longitudinal beam 520 by welding or blind riveting.

[0161] In some possible implementations, the vehicle body also includes a first crossbeam (not shown), which forms the frame structure of the vehicle body. The left and right ends of the first crossbeam are fixedly connected to the left longitudinal beam 510 and the right longitudinal beam 520, respectively, and the support crossbeam 210 is fixedly connected to the first crossbeam.

[0162] This can improve the overall rigidity and strength of the vehicle body, and help reduce the impact of the clearance opening 110 on the overall rigidity and strength of the vehicle body. This allows the vehicle body with the clearance opening 110 in the rear floor 100 to have better rigidity and strength.

[0163] For example, the first crossbeam and the supporting crossbeam 210 can be arranged front to back or vertically. For instance, the first crossbeam can be located below the supporting crossbeam 210 or behind the supporting crossbeam 210.

[0164] In some possible implementations, the support beam 210 has a first connecting hole, the first beam has a second connecting hole opposite to the first connecting hole, and the support beam 210 is fixedly connected to the first beam by fasteners passing through the first connecting hole and the second connecting hole.

[0165] In this way, it is easier to fix the support beam 210 to the first beam.

[0166] For example, the fastener can be a threaded fastener, such as a bolt, which can be threaded with a nut to fix the first sidewall 211 to the first crossbeam.

[0167] For example, the support beam 210 has a plurality of first connecting holes, and the first beam has a plurality of second connecting holes corresponding one-to-one with the first connecting holes. The first connecting holes are opposite to the corresponding second connecting holes, and the support beam 210 is fixedly connected to the first beam by a plurality of fasteners passing through the first connecting holes and the corresponding second connecting holes.

[0168] For example, the support beam 210 includes a first sidewall 211 and a second sidewall 212 disposed opposite to each other, a first connecting hole is located in the first sidewall 211, and the first sidewall 211 is fixedly connected to the first beam by fasteners passing through the first connecting hole and the second connecting hole.

[0169] For example, the supporting beam 210 also includes a third side wall 213 and a fourth side wall 214 disposed opposite to each other. One end of the first side wall 211 is connected to one end of the third side wall 213, the other end of the third side wall 213 is connected to one end of the second side wall 212, the other end of the second side wall 212 is connected to one end of the fourth side wall 214, and the other end of the fourth side wall 214 is connected to the other end of the first side wall 211.

[0170] For example, two left connectors 610 are provided between the left end of the supporting beam 210 and the left longitudinal beam 510. The first connecting part 611 of one left connector 610 is fixedly connected to the third side wall 213, and the first connecting part 611 of the other left connector 610 is fixedly connected to the fourth side wall 214. The second connecting parts 612 of both left connectors 610 are fixedly connected to the left longitudinal beam 510, and the second connecting parts 612 of the two left connectors 610 are spaced apart.

[0171] For example, two right connectors 620 are provided between the right end of the supporting beam 210 and the right longitudinal beam 520. The third connecting part of one right connector 620 is fixedly connected to the third side wall 213, and the third connecting part of the other right connector 620 is fixedly connected to the fourth side wall 214. The fourth connecting parts of both right connectors 620 are fixedly connected to the right longitudinal beam 520, and the fourth connecting parts of the two right connectors 620 are spaced apart.

[0172] In some possible implementations, the second sidewall 212 has a mounting opening 400 opposite to the first connection hole, the mounting opening 400 being for a tool for attaching or removing fasteners to pass through.

[0173] This facilitates the assembly and disassembly of the support beam 210 and the first beam.

[0174] For example, the portion of the fastener between the first sidewall 211 and the second sidewall 212 has its orthographic projection on the first sidewall 211 located within the orthographic projection of the mounting opening 400 on the first sidewall 211. For instance, when the fastener is a bolt, the bolt head is located between the first sidewall 211 and the second sidewall 212, and the orthographic projection of the bolt head on the first sidewall 211 is located within the orthographic projection of the mounting opening 400 on the first sidewall 211.

[0175] When the supporting beam 210 has multiple first connecting holes, the second sidewall 212 has multiple mounting ports 400 that correspond one-to-one with the first connecting holes.

[0176] In some possible implementations, the first crossbeam is located below the rear floor 100, that is, below the support crossbeam 210. The rear floor 100 has a third connecting hole opposite the first connecting hole, and fasteners pass through the first connecting hole, the second connecting hole, and the third connecting hole, the fasteners securing the support crossbeam 210, the rear floor 100, and the first crossbeam together.

[0177] In this way, the first crossbeam does not occupy the space above the rear floor 100, which helps to increase the space inside the vehicle for carrying passengers and cargo. In addition, the fasteners passing through the first connecting hole, the second connecting hole and the third connecting hole facilitate the connection between the rear floor 100 and the support crossbeams 210 and the first crossbeam located above and below the rear floor 100.

[0178] When the supporting crossbeam 210 is located behind the clearance opening 110, the first crossbeam can be located behind the clearance opening 110.

[0179] For example, the first sidewall 211 is located on the lower side of the supporting beam 210, the second sidewall 212 is located on the upper side of the supporting beam 210, the third sidewall 213 is located on the front side of the supporting beam 210, and the fourth sidewall 214 is located on the rear side of the supporting beam 210.

[0180] Figure 5 for Figure 4 The diagram shows a view of the assembly of the partition and support structure provided in the diagram.

[0181] like Figure 4 , Figure 5 As shown, in some possible embodiments, the support structure 200 further includes a support plate structure 220. The support plate structure 220 and the support beam 210 are arranged front and rear, the support plate structure 220 is connected to the support beam 210, the lower end of the support plate structure 220 is connected to the rear floor 100, and the upper end of the support plate structure 220 is connected to the partition 300. The support plate structure 220, the support beam 210 and the partition 300 are used to enclose and form a clearance space.

[0182] This facilitates stable support for the partition 300. Furthermore, the support plate structure 220 helps isolate the clearance space from the vehicle's interior space, making it difficult for noise, dust, water, etc., to enter the vehicle's interior space through the clearance space.

[0183] For example, when the support beam 210 is located in front of the clearance opening 110, the support plate structure 220 is located behind the support beam 210. When the support beam 210 is located behind the clearance opening 110, the support plate structure 220 is located in front of the support beam 210.

[0184] For example, the support plate structure 220 is connected to the third sidewall 213.

[0185] For example, the support plate structure 220 can be connected to the support beam 210 by welding, fastener connection, or other means. For instance, the support plate structure 220 can be connected to the support beam 210 by MIG welding.

[0186] For example, the support plate structure 220 can be connected to the rear floor 100 by welding, fastener connection, or other means. For instance, the support plate structure 220 can be connected to the rear floor 100 by spot welding or blind riveting.

[0187] For example, the support plate structure 220 can be connected to the partition plate 300 by welding, fastener connection, or other means. For instance, the support plate structure 220 can be connected to the partition plate 300 by spot welding or core-pulling riveting.

[0188] In some possible implementations, one end of the support plate structure 220 is connected to the support beam 210 and overlaps the support beam 210, and the support plate structure 220 and the support beam 210 are fixed and sealed together.

[0189] This helps prevent noise, dust, water, and other external factors from entering the vehicle's interior, thus improving the vehicle's sealing and NVH performance.

[0190] For example, one end of the support plate structure 220 connected to the support beam 210 can be bonded to the support beam 210 by structural adhesive provided between the two.

[0191] In some examples, the end of the support plate structure 220 that connects to the support beam 210 can be sealed with a sealant placed between the two.

[0192] In some examples, the support plate structure 220 may be sealed to one end of the support beam 210 by means of a seal (e.g., a gasket) provided between the two.

[0193] In some possible implementations, the end of the support plate structure 220 connected to the support beam 210 has a first flange structure 710, and the support plate structure 220 is connected to the support beam 210 through the first flange structure 710.

[0194] In this way, the connection surface between the support plate structure 220 and the support beam 210 is relatively large, which facilitates the fixing and sealing connection between the support plate structure 220 and the support beam 210.

[0195] In some possible implementations, the lower end of the support plate structure 220 has a second flange structure 720, through which the support plate structure 220 is connected to the rear floor 100.

[0196] In this way, the connection surface between the support plate structure 220 and the rear floor 100 is relatively large, which facilitates the fixing and sealing connection between the support plate structure 220 and the rear floor 100.

[0197] In some possible implementations, the upper end of the support plate structure 220 has a third flange structure 730, through which the support plate structure 220 is connected to the partition plate 300.

[0198] In this way, the connection surface between the support plate structure 220 and the partition plate 300 is relatively large, which facilitates the fixing and sealing connection between the support plate structure 220 and the partition plate 300.

[0199] In some possible implementations, the support plate structure 220 includes a first support plate 221, a second support plate 222, and a third support plate 223. The first support plate 221 and the second support plate 222 are arranged opposite each other from left to right. The third support plate 223 and the support beam 210 are located on the front and rear sides of the first support plate 221 and the second support plate 222, respectively. The front and rear ends of the first support plate 221 are connected to the third support plate 223 and the support beam 210, respectively. The front and rear ends of the second support plate 222 are connected to the third support plate 223 and the support beam 210, respectively.

[0200] The lower ends of the first support plate 221, the second support plate 222, and the third support plate 223 are all connected to the rear floor 100. The upper ends of the first support plate 221, the second support plate 222, and the third support plate 223 are all connected to the partition 300. The first support plate 221, the second support plate 222, the third support plate 223, the support beam 210, and the partition 300 are used to enclose and form a clearance space.

[0201] In this way, it is relatively easy to form the support plate structure 220, and it is relatively convenient to assemble the support structure 200 with the rear floor 100 and the partition 300.

[0202] For example, the support beam 210 is located behind the first support plate 221 and the second support plate 222. The rear ends of the first support plate 221 and the second support plate 222 are connected to the support beam 210. Specifically, the rear ends of the first support plate 221 and the second support plate 222 are connected to the third sidewall 213. The front ends of the first support plate 221 and the second support plate 222 are connected to the third support plate 223.

[0203] For example, the first support plate 221, the second support plate 222 and the third support plate 223 can all be steel plate stampings with a thickness of 1.5mm.

[0204] For example, the first support plate 221 and the second support plate 222 can be connected to the support beam 210 by MIG welding.

[0205] For example, the first support plate 221, the second support plate 222 and the third support plate 223 can all be connected to the rear floor 100 by spot welding or core-pulling riveting.

[0206] For example, the first support plate 221, the second support plate 222 and the third support plate 223 can all be connected to the partition plate 300 by spot welding or core pulling and riveting.

[0207] For example, the first support plate 221 and the second support plate 222 can both be connected to the third support plate 223 by spot welding or core-pulling riveting.

[0208] When assembling the support structure 200, the first support plate 221, the second support plate 222 and the third support plate 223 can be connected to form the support plate structure 220. Then the support plate structure 220 is assembled onto the rear floor 100. After the support plate structure 220 is assembled, the support beam 210 is assembled. After the support plate structure 220 and the support beam 210 are assembled, the partition 300 is assembled.

[0209] For example, the first flange structure 710 includes a first flange portion 711 located on the first support plate 221 and a second flange portion 712 located on the second support plate 222. The first support plate 221 is connected to the support beam 210 through the first flange portion 711, and the second support plate 222 is connected to the support beam 210 through the second flange portion 712, so as to realize the connection between the first support plate 221 and the second support plate 222 and the support beam 210.

[0210] For example, the second flange structure 720 includes a third flange portion 721 located on the first support plate 221, a fourth flange portion 722 located on the second support plate 222, and a fifth flange portion 723 located on the third support plate 223. The first support plate 221 is connected to the rear floor 100 through the third flange portion 721, the second support plate 222 is connected to the rear floor 100 through the fourth flange portion 722, and the third support plate 223 is connected to the rear floor 100 through the fifth flange portion 723, so as to realize the connection between the first support plate 221, the second support plate 222 and the third support plate 223 and the rear floor 100.

[0211] For example, the third flange structure 730 includes a sixth flange portion 731 located on the first support plate 221, a seventh flange portion 732 located on the second support plate 222, and an eighth flange portion 733 located on the third support plate 223. The first support plate 221 is connected to the partition plate 300 through the sixth flange portion 731, the second support plate 222 is connected to the partition plate 300 through the seventh flange portion 732, and the third support plate 223 is connected to the partition plate 300 through the eighth flange portion 733, so as to realize the connection between the first support plate 221, the second support plate 222 and the third support plate 223 and the partition plate 300.

[0212] For example, the first flange 711, the second flange 712, the sixth flange 731, the seventh flange 732, and the eighth flange 733 are all located within the clearance space. The third flange 721, the fourth flange 722, and the fifth flange 723 are all located outside the clearance space.

[0213] In some possible implementations, the third support plate 223 overlaps the end of the first support plate 221 away from the support beam 210 and the end of the second support plate 222 away from the support beam 210. The third support plate 223 is fixed and sealed to the first support plate 221 and to the second support plate 222.

[0214] This helps prevent noise, dust, water, and other external factors from entering the vehicle's interior, thus improving the vehicle's sealing and NVH performance.

[0215] For example, the third support plate 223 and the end of the first support plate 221 away from the support beam 210 can be bonded together with structural adhesive provided between them.

[0216] In some examples, the end of the third support plate 223 away from the first support plate 221 and the support beam 210 can be sealed with a sealant placed between them.

[0217] In some examples, the third support plate 223 and the end of the first support plate 221 away from the support beam 210 can be sealed by a seal (e.g., a gasket) disposed between them.

[0218] For example, the ends of the third support plate 223 and the second support plate 222 away from the support beam 210 can be bonded together with structural adhesive provided between them.

[0219] In some examples, the ends of the third support plate 223 and the second support plate 222 away from the support beam 210 can be sealed with sealant placed between them.

[0220] In some examples, the ends of the third support plate 223 and the second support plate 222 away from the support beam 210 can be sealed by a seal (e.g., a gasket) disposed between them.

[0221] In some possible implementations, the end of the first support plate 221 that connects to the third support plate 223 has a fourth flange structure 740, and the first support plate 221 is connected to the third support plate 223 through the fourth flange structure 740.

[0222] In this way, the connection surface between the first support plate 221 and the third support plate 223 is relatively large, which facilitates the fixing and sealing connection of the first support plate 221 and the third support plate 223.

[0223] In some possible implementations, the end of the second support plate 222 that connects to the third support plate 223 has a fifth flange structure 750, and the second support plate 222 is connected to the third support plate 223 through the fifth flange structure 750.

[0224] In this way, the connection surface between the second support plate 222 and the third support plate 223 is relatively large, which facilitates the fixing and sealing connection of the second support plate 222 and the third support plate 223.

[0225] In some possible implementations, the left end of the partition 300 has a sixth flange structure 760, and the left end of the partition 300 is connected to the left longitudinal beam 510 through the sixth flange structure 760.

[0226] In this way, the connection surface between the partition plate 300 and the left longitudinal beam 510 is relatively large, which facilitates the fixing and sealing connection between the partition plate 300 and the left longitudinal beam 510.

[0227] In some possible implementations, the right end of the partition 300 has a seventh flange structure 770, and the right end of the partition 300 is connected to the right longitudinal beam 520 through the seventh flange structure 770.

[0228] In this way, the connection surface between the partition plate 300 and the right longitudinal beam 520 is relatively large, which facilitates the fixing and sealing connection between the partition plate 300 and the right longitudinal beam 520.

[0229] In some possible implementations, the end of the partition 300 that connects to the second crossbeam 800 has an eighth flange structure 780, and the partition 300 is connected to the second crossbeam 800 through the eighth flange structure 780.

[0230] In this way, the connection surface between the partition 300 and the second crossbeam 800 is relatively large, which facilitates the fixing and sealing connection between the partition 300 and the second crossbeam 800.

[0231] Figure 6 for Figure 4 The diagram shows another perspective of the assembly of the partition and support structure provided in the diagram.

[0232] like Figure 5 , Figure 6 As shown, in some possible embodiments, the support plate structure 220 includes a first structural portion 224 and a second structural portion 225. The lower end of the first structural portion 224 is connected to the rear floor 100, and the second structural portion 225 is located above the first structural portion 224. The upper end of the second structural portion 225 is connected to the partition 300, and both the first structural portion 224 and the second structural portion 225 are connected to the support beam 210. One end of the first structural portion 224 away from the support beam 210 protrudes from the second structural portion 225, and the portion of the clearance opening 110 is located below the portion of the first structural portion 224 that protrudes from the second structural portion 225.

[0233] In this way, for a drive unit with a larger lower dimension and a smaller upper dimension, the area enclosed by the first structural part 224 can avoid the larger lower part of the drive unit, and the area enclosed by the second structural part 225 can avoid the smaller upper part of the drive unit. This minimizes the clearance space and facilitates the arrangement of components on the vehicle body. Furthermore, the larger lower dimension and smaller upper dimension of the support structure 200 make the support structure 200 more stable, which is beneficial for providing stable support for the partition 300. Additionally, it also facilitates the avoidance of components within the vehicle body.

[0234] In some possible implementations, the side of the second structural portion 225 away from the support beam 210 is an inclined structure relative to the rear floor 100, and the upper end of the side of the second structural portion 225 away from the support beam 210 is biased towards the side of the support beam 210 relative to the lower end of the side of the second structural portion 225 away from the support beam 210.

[0235] In this way, the inclined surface improves the stability of the support structure 200, thereby enhancing the stability of the support for the partition 300. Furthermore, it facilitates the avoidance of components within the vehicle body.

[0236] For example, the portion of the third support plate 223 located in the second structural section 225 is an inclined structure relative to the rear floor 100.

[0237] like Figure 1 As shown, in some possible embodiments, the second crossbeam 800 is spaced above the rear floor 100, so that a gap is formed between the second crossbeam 800 and the rear floor 100, and part of the clearance opening 110 is located below the second crossbeam 800. Figure 3 , Figure 5 , Figure 6 As shown, at least a portion of the second structural part 225 is located between the second crossbeam 800 and the supporting crossbeam 210, and the first structural part 224 is inserted into the space, such that a portion of the clearance space is located in the space, and the portion of the clearance space located in the space is connected to the portion of the clearance opening 110 located below the second crossbeam 800.

[0238] In this way, the space between the second crossbeam 800 and the rear floor 100 can be used to avoid the drive unit, resulting in high space utilization and facilitating the compact arrangement of body parts.

[0239] like Figures 4-6 As shown, in some examples, the partition 300 may have a cable routing hole 900 for cable routing. The cable passing through the cable routing hole 900 is sealed to the partition 300 by a sealant (e.g., a sealing sleeve) or sealant, so as to facilitate cable routing while isolating the clearance space from the space inside the vehicle body.

[0240] In some other possible implementations, a fourth support plate may be used instead of the support beam 210, so that the fourth support plate is connected to the support plate structure 220, the rear floor 100, and the partition 300, and the fourth support plate, the support plate structure 220 and the rear floor 100 form a clearance space.

For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components.
