[0047] In the field of battery swapping vehicles, the corresponding battery swapping structure is usually set in the middle chemical compartment assembly of the vehicle body to allow for quick installation and removal of the battery swapping device from the vehicle body.

[0048] However, for vehicles that require battery swapping, the intermediate chemical compartment cannot meet the decoupling requirements, making it difficult for the intermediate chemical compartment to meet the needs of independent maintenance and battery assembly.

[0049] Therefore, the embodiment of the present application provides a vehicle body assembly, the opposite front end and rear end of the rocker beam of the middle chemical cabin are respectively detachably connected with the front cabin framework assembly and the rear floor framework assembly, so as to meet the separation of the middle chemical cabin assembly from the vehicle body assembly. Meanwhile, the battery quick replacement structure is arranged on the rocker beam, that is, on the basis of meeting the separation of the middle chemical cabin, the requirement of the quick replacement battery device can also be met.

[0050] In a first aspect, referring to FIGS. 1-4, the embodiment of the present application provides a vehicle body assembly 100, which includes a front cabin framework assembly 10, a rear floor framework assembly 20, and a middle chemical cabin assembly 30.

[0051] The front cabin framework assembly 10 is used to provide the structural strength of the front part of the vehicle body, effectively disperses the impact force in the event of a collision, and protects the safety of the passengers; provides connection and fixing points for the engine, cooling system, radiator, lamps and other components. The rear floor framework assembly 20 is used to provide the strength and stability of the rear part of the vehicle body, and supports the total amount of the rear seat, luggage compartment and other rear components; in the event of a collision, it can also absorb and disperse impact force, etc. The middle chemical cabin assembly 30 is used to provide the structural strength of the middle part of the vehicle body, and also has a certain energy absorption and impact force dispersion design. At the same time, the middle chemical cabin assembly also needs to accommodate the battery device.

[0052] Specifically, the middle chemical cabin assembly 30 includes a rocker beam 31, the rocker beam 31 has opposite front and rear ends 31a and 32a, the front cabin framework assembly 10 is detachably connected to the front end 31a, and the rear floor framework assembly 20 is detachably connected to the rear end 32a. The rocker beam 31 is provided with a battery quick replacement structure 32, which is used to connect with the battery replacement device 60.

[0053] It can be understood that, for the convenience of understanding, the length direction of the vehicle body assembly 100 can be defined as the X direction, the width direction of the vehicle body assembly 100 is defined as the Y direction, and the height direction of the vehicle body assembly 100 is defined as the Z direction.

[0054] The number of rocker beams 31 of the middle chemical cabin assembly 30 is at least two, each rocker beam 31 is extended along the X direction and spaced apart along the Y direction. The front end 31a and the rear end 32a of the rocker beam 31 are two ends oppositely arranged in the X direction, and are respectively used to connect with the front cabin framework assembly 10 and the rear floor framework assembly 20.

[0055] The detachable connection form of the front cabin framework assembly 10 and the front end 31a includes but is not limited to insertion, clamping, threaded connection, and a combination of insertion, clamping and threaded connection.

[0056] For example, the front end 31a of the rocker beam 31 is provided with a corresponding plug-in hole, and the front end 31a is plugged into the plug-in hole. Of course, when the front end 31a is plugged into the plug-in hole, the front end 31a can also be connected to the front compartment framework assembly 10 by a screw, a pin, or other connecting member for secondary reinforcement.

[0057] The detachable connection form of the rear floor framework assembly 20 and the rear end 31b includes but is not limited to plug-in, clamping, threaded connection, and a combination of plug-in, clamping, and threaded connection.

[0058] For example, the rear end 31b of the rocker beam 31 is provided with a corresponding plug-in hole, and the rear end 31b is plugged into the plug-in hole. Of course, when the rear end 31b is plugged into the plug-in hole, the rear end 31b can also be connected to the rear floor framework assembly 20 by a screw, a pin, or other connecting member for secondary reinforcement.

[0059] The battery quick-change structure 32 is configured to meet the quick disassembly and assembly of the battery replacement device 60 to the rocker beam 31. Here, the battery quick-change structure 32 can be a threaded column structure provided on the rocker beam 31 and matched with a nut structure on the battery replacement device 60 to achieve quick disassembly and assembly. Alternatively, the battery quick-change structure 32 can also be a nut structure provided on the rocker beam 31 and matched with a threaded column structure on the battery replacement device 60. Of course, in other embodiments, the battery quick-change structure 32 includes a threaded column structure and a nut structure provided on the rocker beam 31 and matched with corresponding nut and threaded column structures on the battery replacement device 60.

[0060] In addition, the battery quick-change structure 32 can also be a mounting hole structure formed on the rocker beam 31, which is used to pass and fix the threaded column structure, and then the fixed threaded column structure is matched with the nut structure on the battery replacement device 60 to assemble the battery replacement device 60 to the rocker beam 31. Of course, the mounting hole structure can also be used to fix the nut structure to match the threaded column structure on the battery replacement device 60.

[0061] In summary, the front end 31a and the rear end 32a of the rocker beam 31 of the intermediate chemical cabin assembly 30 can be detachably connected to the front compartment framework assembly 10 and the rear floor framework assembly 20, respectively, and the battery quick-change structure 32 on the rocker beam 31 can also meet the quick-change requirement of the battery replacement 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 requirement and the assembly process requirement of the battery device, and the battery quick-change structure 32 on the rocker beam 31 can also meet the quick assembly requirement of the battery replacement device 60.

[0062] The vehicle body assembly 100 provided by the embodiment of the present application, the middle chemical cabin assembly 30 can be connected to the front cabin framework assembly 10 and the rear floor framework assembly 20 through the first fastener 40 and the second fastener 50 respectively, specifically, the front end 31a of the rocker beam 31 of the middle chemical cabin assembly 30 is connected to the front cabin framework assembly 10 through the first fastener 40, and the rear end 32a of the rocker beam 31 is connected to the rear floor framework assembly 20 through the second fastener 50, that is, after the first fastener 40 and the second fastener 50 are removed, the middle chemical cabin assembly 30 can be separated from the front cabin framework assembly 10 and the rear floor framework assembly 20 to meet the needs of separate maintenance or battery device assembly of the middle chemical cabin assembly 30, and the battery quick replacement structure 32 is further arranged on the rocker beam 31, that is, the battery quick replacement structure 32 is used to quickly disassemble and assemble the battery replacement device 60 and the middle chemical cabin assembly 30 to meet the needs of battery replacement, so that the vehicle body assembly 100 provided by the embodiment of the present application can meet the needs of battery replacement, and the middle chemical cabin assembly 30 can be separated independently, that is, the needs of separate maintenance and direct assembly of the battery device can be met.

[0063] Please refer to FIG. 4 and FIG. 5, in an embodiment, the battery quick replacement structure 32 includes a connecting column 321 arranged on the rocker beam 31, and the connecting column 321 is used to adaptively connect with the battery replacement device 60.

[0064] It can be understood that the connecting column 321 is adapted to the structure with a hole structure in the battery replacement device 60, and the connecting column 321 can be a threaded column, a pin column and a riveting column, etc., wherein when the connecting column 321 is a threaded column, the nut in the battery replacement device 60 can be quickly disassembled and assembled, that is, the needs of high-efficiency disassembly and assembly between the battery replacement device 60 and the rocker beam 31 can be met.

[0065] Meanwhile, the arrangement position of the connecting column 321 on the rocker beam 31 can be adaptively adjusted, for example, a plurality of connecting columns 321 are arranged along the length direction of the vehicle body assembly 100, that is, the X direction.

[0066] In addition, the connecting form of the connecting column 321 and the rocker beam 31 can be fixed connection, for example, welding, riveting, etc., or detachable connection, for example, insertion, clamping and threaded connection, etc.

[0067] In this way, the connecting column 321 is used for connecting the battery replacement device 60 to meet the needs of battery quick replacement.

[0068] In an embodiment, the connecting column 321 is detachably connected to the rocker beam 31.

[0069] It can be understood that the detachable connection form of the connecting column 321 and the rocker beam 31 can be insertion, clamping and threaded connection, etc.

[0070] For example, a corresponding opening is formed on the rocker beam 31, the connecting column 321 is arranged in the opening, and then a structure on the battery replacement device 60 that is connected to the connecting column 321 is connected to the connecting column 321, so as to fix the battery replacement device 60 on the rocker beam 31.

[0071] For example, a corresponding threaded hole is formed on the rocker beam 31, the connecting column 321 is screwed into the threaded hole, and then a structure on the battery replacement device 60 that is connected to the connecting column 321 is connected to the connecting column 321, so as to fix the battery replacement device 60 on the rocker beam 31.

[0072] In summary, since the connecting column 321 needs to be connected to the battery replacement device 60 for a long time and belongs to a consumable part, the connecting column 321 is detachably connected to the rocker beam 31, so that the connecting column 321 can be replaced in time, thereby prolonging the service life of the rocker beam 31.

[0073] In this way, the connecting column 321 can be disassembled and assembled on the rocker beam 31 according to actual use requirements.

[0075] 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 passes through the through hole structure 32a, so that the connecting column 321 can be easily taken out from the through hole structure 32a under non-use conditions. Therefore, the clamping portion 3211 is difficult 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 of the clamping portion 3211 is difficult to adapt to the hole shape of the through hole structure 32a, etc. The connecting portion 3212 is threadedly connected to the battery replacement device 60, that is, the connecting portion 3212 should have external threads that are adapted to the battery replacement device 60.

[0076] In this way, the clamping portion 3211 of the connecting column 321 is clamped on the through hole structure 32a to achieve fixation, and the connecting portion 3212 is threadedly connected to the battery replacement device to achieve fixation.

[0077] Please refer to FIG. 1 and FIG. 4, in one embodiment, the number of threshold beams 31 is at least two, each threshold beam 31 is arranged at intervals, the intermediate chemical cabin assembly 30 further comprises a middle cross beam 33 connecting any two adjacent threshold beams 31, wherein one of the middle cross beams 33 is provided with a quick plug wire harness connector 34, which is used for electrical connection with the battery swap device 60.

[0078] It can be understood that the middle cross beam 33 is a beam structure arranged along the width direction of the vehicle body assembly 100, that is, along the Y direction, and the middle cross beam 33 and the threshold beam 31 form a frame structure, of course, in order to improve the stability of the frame structure, a plurality of middle cross beams 33 can be arranged between the two adjacent threshold beams 31.

[0079] At the same time, in addition to the spatial structure of the battery swap device 60 connected with the intermediate chemical cabin assembly 30, it also needs to be electrically connected with the intermediate chemical cabin assembly 30, so that various wire harnesses are integrated in the intermediate chemical cabin assembly 30, for example, the threshold beam 31 and the middle cross beam 33 are arranged as a hollow structure, the wire harness is integrated in any one or both of the threshold beam 31 and the middle cross beam 33, and the quick plug wire harness connector 34 is arranged on one of the middle cross beams 33, and the quick plug wire harness connector 34 is inserted with the interface of the battery swap device 60 to realize the electrical connection between them.

[0080] In this way, the middle cross beam 33 and the threshold beam 31 form a frame structure, and at the same time, the battery swap device 60 is physically connected with the battery quick change structure 32 on the threshold beam 31, and the battery swap device 60 is electrically connected with the quick plug wire harness connector 34 on the middle cross beam 33.

[0081] Please refer to FIG. 1 and FIG. 4, in one embodiment, the vehicle body assembly 100 further comprises a first fastener 40; the front cabin framework assembly 10 is connected with the front end 31a through the first fastener 40.

[0083] The front end 31a is connected to the front compartment framework assembly 10 by the first fasteners 40. The number and arrangement direction of the first fasteners 40 can be variously selected. For example, a part of the first fasteners 40 are arranged along the Y direction to connect the front end 31a and the front compartment framework assembly 10, another part of the first fasteners 40 are arranged along the Z direction to connect the front end 31a and the front compartment framework assembly 10, or the arrangement direction of the first fasteners 40 can be at an angle with respect to the Y direction, and the arrangement direction of the first fasteners 40 can also be at an angle with respect to the Z direction.

[0084] In this way, the front compartment framework assembly 10 is detachably connected to the front end 31a by the first fasteners 40, and the connection stability and disassembly efficiency are higher.

[0085] Referring to FIGS. 1 and 2, in an embodiment, the front compartment framework assembly 10 includes a front compartment cross beam 11 and a front compartment longitudinal beam 12 connected to the front compartment cross beam 11. The front compartment cross beam 11 and / or the front compartment longitudinal beam 12 are connected to the front end 31a by the first fasteners 40.

[0086] It can be understood that the front compartment cross beam 11 is a beam structure extending along the width direction of the vehicle body assembly 100, i.e., extending along the Y direction, and the front compartment longitudinal beam 12 is a beam structure extending along the length direction of the vehicle body assembly 100, i.e., extending along the X direction.

[0087] In terms of connection, the first fasteners 40 can be connected to the front end 31a of the rocker beam 31 by being arranged through any one or both of the front compartment cross beam 11 and the front compartment longitudinal beam 12. Here, the first fasteners 40 arranged through the front compartment cross beam 11 can be along the Y direction, or at an angle with respect to the Y direction, and / or the first fasteners 40 arranged through the front compartment longitudinal beam 12 can be along the Z direction, or at an angle with respect to the Z direction.

[0088] In this way, any one or both of the front compartment cross beam 11 and the front compartment longitudinal beam 12 can be connected to the front end 31a of the rocker beam 31 by the first fasteners 40 to meet the detachable connection of the front compartment framework assembly 10 and the intermediate chemical tank assembly 30.

[0089] Referring to FIGS. 1 and 2, in an embodiment, a part of the first fasteners 40 are arranged along a first direction through the rocker beam 31 and the front compartment cross beam 11, and another part of the first fasteners 40 are arranged along a second direction through the rocker beam 31 and the front compartment longitudinal beam. The first direction and the second direction are arranged at an angle.

[0090] It can be understood that the first direction is any direction that can satisfy the first fastener 40 penetrating the rocker beam 31 and the front compartment cross beam 11 at the same time, and the second direction is any direction that can satisfy the first fastener 40 penetrating the rocker beam 31 and the front compartment longitudinal beam 12 at the same time, and the first direction and the second direction are arranged at an included angle, and the included angle can be an acute angle or an obtuse angle.

[0091] For example, 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 arranged perpendicular to each other, so that the rocker beam 31 obtains two mutually perpendicular connection forces, further improving the stability of the connection between the middle chemical tank assembly 30 and the front compartment frame assembly 10.

[0092] In this way, the first fastener 40 is divided into two parts, and the connection of the front compartment cross beam 11 and the front compartment longitudinal beam 12 with the rocker beam 31 is realized from the first direction and the second direction respectively, thereby improving the reliability of the connection between the front compartment frame assembly 10 and the rocker beam 31 on the basis of meeting the detachable connection.
