[0053] In the field of related battery swapping vehicle models, a corresponding battery swapping battery structure is usually provided at the middle chemical cabin assembly of the vehicle body to enable the battery swapping battery device to be quickly disassembled and assembled on the vehicle body.

[0054] However, on this basis, for models with vehicle-level battery swapping, the intermediate chemical cabin is difficult to meet the decoupling requirements. Thus, it is difficult for the intermediate chemical cabin to meet the needs of separate maintenance and battery device assembly.

[0055] In view of this, the embodiment of the present application provides a body assembly. The front end and the rear end of the sill beam of the intermediate chemical cabin are detachably connected to the front cabin frame assembly and the rear floor frame assembly respectively, so as to satisfy that the intermediate chemical cabin assembly can be separated from the body assembly. Meanwhile, a battery quick replacement structure is also provided on the sill beam, that is, on the basis of satisfying the separability of the intermediate chemical cabin, the need for quick replacement of the battery device can also be met.

[0056] In the first aspect, please refer to Figures 1 to 4 , the embodiment of the present application provides a body assembly 100, including a front cabin frame assembly 10, a rear floor frame assembly 20, and an intermediate chemical cabin assembly 30.

[0057] Among them, the front cabin frame assembly 10 is used to provide the structural strength of the front part of the vehicle body, and can effectively disperse the impact force during a collision to protect the safety of the occupants; it provides connection and fixing points for the engine, cooling system, radiator, lamps, etc. The rear floor frame assembly 20 is used to provide the strength and stability of the rear part of the vehicle body, and at the same time support the total weight of the rear seats, luggage compartment and other rear components; during a collision, it can also absorb and disperse the impact force, etc. The intermediate chemical cabin assembly 30 is used to provide the structural strength of the middle part of the vehicle body, and also has a design for absorbing energy and dispersing the impact force to a certain extent. At the same time, the intermediate chemical cabin assembly also needs to accommodate the battery device.

[0058] Specifically, the intermediate chemical cabin assembly 30 includes a sill beam 31. The sill beam 31 has a front end 31a and a rear end 32a which are oppositely arranged. The front cabin frame assembly 10 is detachably connected to the front end 31a, and the rear floor frame assembly 20 is detachably connected to the rear end 32a. A battery quick replacement structure 32 is provided on the sill beam 31, and the battery quick replacement structure 32 is used to connect with the battery swapping device 60.

[0059] It can be understood that, for the convenience of understanding, the length direction of the body assembly 100 can be defined as the X direction, the width direction of the body assembly 100 can be defined as the Y direction, and the height direction of the body assembly 100 can be defined as the Z direction.

[0060] The number of the sill beams 31 of the intermediate chemical cabin assembly 30 is at least two. Each sill beam 31 extends along the X direction and is arranged at intervals along the Y direction. The front end 31a and the rear end 32a of the sill beam 31 are two opposite ends in the X direction, and are respectively used to connect with the front cabin frame assembly 10 and the rear floor frame assembly 20.

[0061] The detachable connection forms between the front cabin skeleton assembly 10 and the front end 31a include, but are not limited to, plug-in connection, snap connection, threaded connection, and combinations of plug-in connection, snap connection, and threaded connection.

[0062] Exemplarily, corresponding plug-in holes are provided on the front cabin skeleton assembly 10 to insert the front end into the plug-in holes. Of course, while the front cabin skeleton assembly 10 is plugged into the front end 31a, secondary reinforcement can also be achieved through connecting components such as screws and pins.

[0063] The detachable connection forms between the rear floor skeleton assembly 20 and the rear end 31b include, but are not limited to, plug-in connection, snap connection, threaded connection, and combinations of plug-in connection, snap connection, and threaded connection.

[0064] Exemplarily, corresponding plug-in holes are provided on the rear floor skeleton assembly 20 to insert the rear end 31b into the plug-in holes. Of course, while the rear floor skeleton assembly 20 is plugged into the rear end 31b, secondary reinforcement can also be achieved through connecting components such as screws and pins.

[0065] The battery quick-change structure 32 enables the quick disassembly and assembly of the battery-changing battery device 60 on the sill beam 31. Here, the battery quick-change structure 32 can be a threaded columnar structure provided on the sill beam 31, which is adapted to the nut structure on the battery-changing battery device 60 to achieve quick disassembly and assembly; or, the battery quick-change structure 32 can also be a nut structure provided on the sill beam 31, which is adapted to the threaded columnar structure on the battery-changing battery device 60. Of course, in other embodiments, the battery quick-change structure 32 includes a threaded columnar structure and a nut structure provided on the sill beam 31, which are adaptively connected to the corresponding nut structure and threaded columnar structure on the battery-changing battery device 60.

[0066] In addition, the battery quick-change structure 32 can also be an installation hole structure formed on the sill beam 31. The installation hole structure is used for the threaded columnar structure to pass through and be fixed. Then, the fixed threaded columnar structure is adapted to the nut structure on the battery-changing battery device 60 to assemble the battery-changing battery device 60 on the sill beam 31. Of course, the installation hole structure can also be used to fix the nut structure to be adapted to the threaded columnar structure on the battery-changing battery device 60.

[0067] In summary, the front end 31a and the rear end 32a of the sill beam 31 of the intermediate chemical cabin assembly 30 can respectively be detachably connected to the front cabin skeleton assembly 10 and the rear floor skeleton assembly 20, and the battery quick-change structure 32 located on the sill beam 31 can also meet the quick-change requirements of the battery-changing battery device 60. In this way, the intermediate chemical cabin assembly 30 can be separated from the vehicle body assembly 100 to meet the independent maintenance requirements and the assembly process requirements of the battery device. At the same time, the battery quick-change structure 32 on the sill beam 31 can also meet the quick assembly requirements of the battery-changing battery device 60.

[0068] For the vehicle body assembly 100 provided by the present utility model, the intermediate chemical cabin assembly 30 can be connected to the front cabin skeleton assembly 10 and the rear floor skeleton assembly 20 respectively through the first fastener 40 and the second fastener 50. Specifically, the front end 31a of the sill beam 31 of the intermediate chemical cabin assembly 30 is connected to the front cabin skeleton assembly 10 through the first fastener 40, and the rear end 32a of the sill beam 31 is connected to the rear floor skeleton assembly 20 through the second fastener 50. That is, after removing the first fastener 40 and the second fastener 50, the intermediate chemical cabin assembly 30 can be separated from the front cabin skeleton assembly 10 and the rear floor skeleton assembly 20 to meet the requirements of separate maintenance of the intermediate chemical cabin assembly 30 or the assembly of the battery device. At the same time, a battery quick change structure 32 is also provided on the sill beam 31, that is, the battery quick change structure 32 is used to realize the quick disassembly and assembly of the battery swapping device 60 and the intermediate chemical cabin assembly 30 to meet the battery swapping requirements. Thus, for the vehicle body assembly 100 provided by the embodiment of the present application, the intermediate chemical cabin assembly 30 can meet the battery swapping requirements, and at the same time, the intermediate chemical cabin assembly 30 can also be separately separated, that is, it can also meet the requirements of separate maintenance and direct assembly of the battery device.

[0069] Please refer to Figure 4 and Figure 5 In one embodiment, the battery quick change structure 32 includes a connection column 321 provided on the sill beam 31, and the connection column 321 is used for adaptively connecting to the battery swapping device 60.

[0070] It can be understood that the connection column 321 is adapted to a structural member with a hole structure in the battery swapping device 60. The connection column 321 can be a threaded column, a pin column, a riveting column, etc. When the connection column 321 is a threaded column, it can achieve quick disassembly and assembly with the nut in the battery swapping device 60, that is, it can meet the relatively high efficiency requirements for disassembly and assembly between the battery swapping device 60 and the sill beam 31.

[0071] At the same time, the setting position of the connection column 321 on the sill beam 31 can be adjusted adaptively. For example, each connection body is arranged at equal intervals along the length direction of the vehicle body assembly 100, that is, the X direction.

[0072] In addition, the connection form between the connection column 321 and the sill beam 31 can be a fixed connection, such as welding, riveting, etc.; it can also be a detachable connection, such as plugging, clamping, and threaded connection, etc.

[0073] Thus, the connection column 321 is used for the battery swapping device 60 to connect to meet the battery quick change requirements.

[0074] In one embodiment, the connection column 321 is detachably connected to the sill beam 31.

[0075] It is understandable that the detachable connection between the connecting column 321 and the door sill beam 31 can be in the form of plug-in connection, clip-on connection, threaded connection, etc.

[0076] For example, a corresponding opening is opened on the door sill beam 31, and the connecting column 321 is passed through the opening. Then, the structural part on the battery replacement device 60 that is adapted to be connected to the connecting column 321 is connected to the connecting column 321 to fix the battery replacement device 60 on the door sill beam 31.

[0077] For example, a corresponding threaded hole is opened on the door sill beam 31, and the connecting column 321 is screwed into the threaded hole. Similarly, the structural part on the battery replacement device 60 that is adapted to connect with the connecting column 321 is connected to the connecting column 321 to fix the battery replacement device 60 on the door sill beam 31.

[0078] In summary, since the connecting column 321 needs to be adapted and connected with the battery replacement device 60 for a long time and is a consumable part, the connecting column 321 is detachably connected to the threshold beam 31 to facilitate timely replacement of the connecting column 321, thereby improving the service life of the threshold beam 31.

[0079] In this way, the connecting column 321 can be disassembled and assembled on the door sill beam 31 according to actual use requirements.

[0080] Please refer to Figure 4 and Figure 5 In one embodiment, a through-hole structure 32a is provided on the door sill beam 31, and the connecting column 321 includes a clamping portion 3211 clamped at the through-hole structure 32a and a connecting portion 3212 extending outward from the clamping portion 3211, and the connecting portion 3212 is threadedly connected to the battery replacement device 60.

[0081] It can be understood that the clamping portion 3211 of the connecting column 321 can be clamped on the periphery of the through-hole structure 32a, and the connecting portion 3212 can be passed through the through-hole structure 32a, so that the connecting column 321 can be easily removed from the through-hole structure 32a when not in use. Therefore, it is difficult for the clamping portion 3211 to pass through the through-hole structure 32a. For example, the size of the clamping portion 3211 is larger than the size of the through-hole structure 32a, or the shape and structure of the clamping portion 3211 is difficult to adapt to the hole shape of the through-hole structure 32a. The connecting portion 3212 is threadedly adapted to the battery-exchange device 60, that is, the connecting portion 3212 should have an external thread adapted thereto, and the battery-exchange battery device 60 should be provided with a nut threadedly adapted to the connecting portion 3212.

[0082] In this way, the clamping portion 3211 of the connecting column 321 is clamped with the through-hole structure 32a to achieve fixation, and at the same time, the connecting portion 3212 is threadedly connected and fixed to the battery replacement device.

[0083] Please refer to Figure 1 and Figure 4 , in one embodiment, the number of the sill beams 31 is at least two, and the sill beams 31 are arranged at intervals. The intermediate chemical tank assembly 30 further includes an intermediate cross beam 33 connecting any two adjacent sill beams 31. A quick-connect wiring harness connector 34 is provided on one of the intermediate cross beams 33, and the quick-connect wiring harness connector 34 is used for electrically connecting with the battery swapping device 60.

[0084] It can be understood that the intermediate cross beam 33 is a beam structure arranged along the width direction of the vehicle body assembly 100, that is, along the Y direction. The intermediate cross beam 33 and the sill beam 31 enclose a frame structure. Of course, in order to improve the stability of the frame structure, a plurality of intermediate cross beams 33 can be provided between two adjacent sill beams 31 arranged adjacent to each other.

[0085] Meanwhile, in addition to being connected to the intermediate chemical tank assembly 30 in terms of spatial structure, the battery swapping device 60 also needs to be electrically connected to the intermediate chemical tank assembly 30. Therefore, various wiring harnesses are integrated in the intermediate chemical tank assembly 30. For example, the sill beam 31 and the intermediate cross beam 33 are arranged as hollow structures, and the wiring harness is integrated in any one or both of the sill beam 31 and the intermediate cross beam 33. And, the quick-connect wiring harness connector 34 is provided on one of the intermediate cross beams 33, and the quick-connect wiring harness connector 34 is plugged into the interface of the battery swapping device 60 to realize the electrical connection between the two.

[0086] In this way, the intermediate cross beam 33 and the sill beam 31 enclose a frame structure. At the same time, the battery swapping device 60 makes a physical connection with the battery quick swapping structure 32 on the sill beam 31, and the battery swapping device 60 makes an electrical connection with the quick-connect wiring harness connector 34 on the intermediate cross beam 33.

[0087] Please refer to the figure. In one embodiment, the vehicle body assembly 100 further includes a first fastener 40; the front cabin skeleton assembly 10 is connected to the front end 31a through the first fastener 40.

[0088] It can be understood that the structural form of the first fastener 40 includes but is not limited to screws, rivets, pins, etc. The first fastener 40 is used to connect the front cabin skeleton assembly 10 to the intermediate chemical tank assembly 30. At the same time, after the first fastener 40 is disassembled, the two can be separated.

[0089] Moreover, the front end 31a is connected to the front cabin frame assembly 10 by the first fasteners 40. The number and arrangement direction of the first fasteners 40 can have various options. For example, some of the first fasteners 40 are inserted along the Y direction to connect the front end 31a and the front cabin frame assembly 10, and some of the first fasteners 40 are inserted along the Z direction to connect the front end 31a and the front cabin frame assembly 10. Alternatively, the insertion and installation direction of the first fasteners 40 can also be along a direction forming an angle with the Y direction, and the insertion direction of the first fasteners 40 can also be along a direction forming an angle with the Z direction.

[0090] In this way, the front cabin frame assembly 10 is detachably connected to the front end 31a by the first fasteners 40, and both the connection stability and the disassembly and assembly efficiency are higher.

[0091] Please refer to Figure 1 and Figure 2 In one embodiment, the front cabin frame assembly 10 includes a front cabin cross beam 11 and a front cabin longitudinal beam 12 connected to the front cabin cross beam 11. The front cabin cross beam 11 and / or the front cabin longitudinal beam 12 are connected to the front end 31a of the sill beam 31 by the first fasteners 40.

[0092] It can be understood that the front cabin cross beam 11 extends along the width direction of the vehicle body assembly 100, that is, a beam structure extending along the Y direction, and the front cabin longitudinal beam 12 extends along the length direction of the vehicle body assembly 100, that is, a beam structure extending along the X direction.

[0093] In terms of connection options, the first fasteners 40 can be connected to the front end 31a of the sill beam 31 by passing through either or both of the front cabin cross beam 11 and the front cabin longitudinal beam 12. Here, the direction of the first fasteners 40 passing through the front cabin cross beam 11 can be along the Y direction, or a direction forming an angle with the Y direction, and / or the direction of the first fasteners 40 passing through the front cabin longitudinal beam 12 can be along the Z direction, or a direction forming an angle with the Z direction.

[0094] In this way, either or both of the front cabin cross beam 11 and the front cabin longitudinal beam 12 can be selected to be connected to the front end 31a of the sill beam 31 by the first fasteners 40 to meet the detachable connection between the front cabin frame assembly 10 and the intermediate chemical cabin assembly 30.

[0095] Please refer to Figure 1 and Figure 2 In one embodiment, some of the first fasteners 40 are inserted through the sill beam 31 and the front cabin cross beam 11 along the first direction; and some of the other first fasteners 40 are inserted through the sill beam 31 and the front cabin longitudinal beam along the second direction, and the first direction and the second direction are arranged at an angle.

[0096] Understandably, the first direction is any direction that can satisfy the first fastener 40 passing through the sill beam 31 and the front cabin cross beam 11 at the same time, and the second direction is any direction that can satisfy the first fastener 40 passing through the sill beam 31 and the front cabin longitudinal beam 12 at the same time. Moreover, the first direction and the second direction are arranged at an angle, where this angle can be an acute angle or an obtuse angle.

[0097] Exemplarily, the first direction can be the Y direction, and the second direction can be the Z direction, that is, the first direction and the second direction are perpendicularly arranged. In this way, the sill beam 31 obtains connecting forces in two mutually perpendicular directions, further improving the stability of the connection between the intermediate chemical cabin assembly 30 and the front cabin skeleton assembly 10.

[0098] In this way, the first fasteners 40 are divided into two parts, and the front cabin cross beam 11 and the front cabin longitudinal beam 12 are respectively connected to the sill beam 31 from the first direction and the second direction. Furthermore, on the basis of meeting the detachable connection, the reliability of the connection between the front cabin skeleton assembly 10 and the sill beam 31 is improved.

[0099] Please refer to the figure. In one embodiment, the vehicle body assembly 100 further includes a second fastener 50; the rear floor skeleton assembly 20 is connected to the rear end 31b through the second fastener 50.

[0100] Understandably, the structural form of the second fastener 50 includes but is not limited to screws, rivets, pins, etc. The second fastener 50 is used to connect the rear floor skeleton assembly 20 and the intermediate chemical cabin assembly 30. After the second fastener 50 is disassembled, the rear floor skeleton assembly 20 and the intermediate chemical cabin assembly 30 can be separated again. In this way, the intermediate chemical cabin assembly 30 can be separately separated from the front cabin fastener assembly and the rear floor skeleton assembly of the vehicle body assembly 100 to meet the requirements of independent maintenance and the process requirements for directly installing the battery device on the intermediate chemical cabin assembly 30.

[0101] Moreover, the rear end 32a is connected to the rear floor skeleton assembly 20 through the second fastener 50. The number and installation direction of the second fastener 50 can have various choices. For example, a part of the second fastener 50 passes through along the Y direction to connect the rear end 32a and the rear floor skeleton assembly 20, and another part of the second fastener 50 passes through along the Z direction to connect the rear end 32a and the rear floor skeleton assembly 20. Or, the installation direction of the second fastener 50 passing through can also be along a direction at an angle with the Y direction, and the passing direction of the second fastener 50 can also be along a direction at an angle with the Z direction.

[0102] In this way, the rear floor skeleton assembly 20 is detachably connected to the rear end through the second fastener 50, and both the connection stability and the disassembly and assembly efficiency are higher.

[0103] Please refer to Figure 1 and Figure 3 In one embodiment, the rear floor frame assembly 20 includes a rear longitudinal beam 21, and the rear longitudinal beam 21 is connected to the rear end 32a through a second fastener 50.

[0104] Understandably, the rear longitudinal beam 21 is a beam structure that extends along the length direction of the vehicle body assembly 100, that is, along the X direction, in the rear floor frame assembly 20.

[0105] In terms of connection selection, the second fastener 50 can be connected to the front end 31a of the sill beam 31 by passing through the rear longitudinal beam 21. Here, the direction in which the second fastener 50 passes through the rear longitudinal beam 21 can be along the Y direction, or a direction at an angle to the Y direction, and / or the direction in which the second fastener 50 passes through the rear longitudinal beam 21 can be along the Z direction, or a direction at an angle to the Z direction.

[0106] In this way, the rear longitudinal beam 21 is connected to the rear end 32a through the second fastener 50 to satisfy the detachable connection between the rear floor frame assembly 20 and the intermediate chemical tank assembly 30.

[0107] Please refer to Figure 1 and Figure 3 In one embodiment, a part of the second fasteners 50 pass through the sill beam 31 and the rear longitudinal beam 21 in a first direction; and another part of the second fasteners 50 pass through the sill beam 31 and the rear longitudinal beam 21 in a second direction, and the first direction and the second direction are arranged at an angle.

[0108] Understandably, the first direction is any direction that can satisfy the second fastener 50 passing through the sill beam 31 and the rear longitudinal beam 21 at the same time, and the second direction is any direction that can satisfy the second fastener 50 passing through the sill beam 31 and the rear longitudinal beam 21 at the same time, and the first direction and the second direction are arranged at an angle. Here, the angle can be an acute angle or an obtuse angle.

[0109] Exemplarily, the first direction can be the Y direction, and the second direction can be the Z direction, that is, the first direction and the second direction are perpendicularly arranged, and the rear longitudinal beam 21 has a side wall surface perpendicular to the Y direction and a top surface perpendicular to the Z direction. In this way, a part of the second fasteners 50 pass through the side wall surface to be connected to the sill beam 31, and another part of the second fasteners 50 pass through the top surface to be connected to the sill beam 31. Then, the sill beam 31 obtains connection forces in two mutually perpendicular directions, further improving the connection stability between the intermediate chemical tank assembly 30 and the rear floor frame assembly 20.

[0110] Thus, each second fastener 50 is divided into two parts, and the connection between the rear longitudinal beam 21 and the sill beam 31 is realized from the first direction and the second direction respectively. Furthermore, on the basis of meeting the detachable connection, the reliability of the connection between the rear floor skeleton assembly 20 and the sill beam 31 is improved.
