[0029] With the vigorous development of the automobile industry, the domestic SUV market has gradually emerged. Fastback SUVs combine the high body of ordinary SUVs with the smooth roof lines of sedans, combining sportiness and practicality, providing consumers with more choices. However, the fastback design makes the center of gravity of the vehicle relatively high. When the vehicle is driving at high speed, the Y-axis yaw and vibration of the body are obvious, and the comfort is poor.

[0030] Reference below Figure 1-Figure 4 A vehicle body assembly according to an embodiment of the present invention is described.

[0031] The vehicle body assembly 1 according to the present invention includes a side panel assembly 11, a floor assembly 12 and a connecting plate 13. A wheel cover 121 and a lap plate 122 that fits the wheel cover 121 are formed on the floor assembly 12. One end of the lap plate 122 is connected to the bottom wall of the floor assembly 12, and the other end of the lap plate 122 extends to the side panel assembly 11 and connects the side panel assembly 11 to the floor assembly 12. One end of the connecting plate 13 is connected to the side panel assembly 11, and the other end of the connecting plate 13 is connected to the lap plate 122.

[0032] According to the vehicle body assembly 1 of the present invention, a floor assembly 12 is provided, a wheel cover 121 is formed on the floor assembly 12, and a side panel assembly 11 is provided on one side edge of the wheel cover 121. During assembly, the side panel assembly 11 and the floor assembly 12 can be spliced ​​and combined. The spliced ​​floor assembly 12 and the side panel assembly 11 will form an annular structure due to the shape of the wheel cover 121. The lap plate 122 fits the wheel cover 121, and one end of the lap plate 122 extends along the surface of the wheel cover 121 to the floor assembly 12, so that the connection between the floor assembly 12 and the wheel cover 121 is more stable. The other end of the lap plate 122 can fit at least part of the side panel assembly 11 to achieve the connection between the side panel assembly 11, the wheel cover 121 and the floor assembly 12. The provision of the lap plate 122 enables the floor assembly 12 and the side panel assembly 11 to be spliced ​​into a whole, thereby improving the stability of the connection between the side panel assembly 11 and the floor assembly 12. At this time, one end of the connecting plate 13 is connected to the lap plate 122, and the other end of the connecting plate 13 is connected to the side panel assembly 11, which can reduce the looseness between the side panel assembly 11 and the floor assembly 12, effectively enhance the rigidity and stability of the overall structure after the side panel assembly 11 and the floor assembly 12 are spliced, reduce the Y-axis sway and vibration of the vehicle body, and improve the comfort and driving experience of the vehicle.

[0033] According to one embodiment of the present invention, an arc segment 1221 is formed on the lap plate 122, which is in contact with at least part of the surface of the wheel cover 121, and the connecting plate 13 is spaced apart from the arc segment 1221. The arc segment 1221 formed on the lap plate 122, which is in contact with at least part of the surface of the wheel cover 121, is designed to increase the contact area between the lap plate 122 and the wheel cover 121, and can form a good transition between the wheel cover 121 and the side enclosure assembly 11, thereby enhancing the stability of the connection between the side enclosure assembly 11 and the wheel cover 121, helping to reduce vibration and noise caused by uneven road surface or turning during vehicle driving, and improving the overall rigidity of the vehicle body. During assembly, the connecting plate 13 is designed to be spaced apart from the arc segment 1221 so as to form a triangular stable area between the connecting plate 13 and the arc segment 1221, thereby improving the connection stability among the connecting plate 13, the lap plate 122 and the side panel assembly 11, thereby improving the rigidity of the vehicle body assembly 1, reducing the vibration and sway of the vehicle, and improving the safety of the vehicle.

[0034] According to one embodiment of the present invention, the connecting plate 13 includes: a first mating segment 131, a second mating segment 132 and a connecting segment 133, the first mating segment 131 is formed with a first mating area that fits with the side panel assembly 11; at least a portion of the second mating segment 132 is formed with a second mating area that fits with the lap plate 122; the connecting segment 133 connects the first mating segment 131 with the second mating segment 132, and the connecting segment 133 is spaced apart from the arc segment 1221.

[0035] The connecting plate 13 can be subdivided into a first mating section 131, a second mating section 132 and a connecting section 133. The segmented design increases the contact area and connection points between the connecting plate 13 and other parts of the vehicle body (such as the side panel assembly 11 and the lap plate 122), thereby enhancing the stability of the structural connection. Specifically, the first mating area on the first mating section 131 fits tightly with the side panel assembly 11, and the second mating area on the second mating section 132 fits with the lap plate 122. This multi-point connection method enables the vehicle body assembly 1 to disperse stress more evenly when subjected to force, thereby improving the overall strength and durability. At the same time, the segmented design of the connecting plate 13 makes the assembly process more flexible and efficient. Each mating section has a clear fitting area, which can be more easily adjusted and positioned during assembly, reducing assembly errors. The spacing design between the connecting section 133 and the arc section 1221 also provides more assembly space, which is convenient for workers to operate and improves assembly efficiency.

[0036] According to one embodiment of the present invention, a first mounting hole 1311 is formed in the first matching area, and a first matching hole 111 corresponding to the first mounting hole 1311 is formed on the side enclosure assembly 11; a second mounting hole 1321 is formed in the second matching area, and a second matching hole 1222 corresponding to the second mounting hole 1321 is formed on the lap plate 122. By forming the first mounting hole 1311 in the first matching area, and correspondingly forming the first matching hole 111 on the side enclosure assembly 11, and forming the second mounting hole 1321 in the second matching area, and correspondingly forming the second matching hole 1222 on the lap plate 122, the connecting plate 13 can be firmly connected to the side enclosure assembly 11 and the lap plate 122 using fasteners (such as bolts, nuts or rivets) during assembly, thereby enhancing the stability between the components and improving the overall strength and durability of the vehicle body assembly 1. The design of the mounting holes and matching holes provides clear positioning points for the assembly process, making the assembly more precise, and workers can easily align the holes and fix them together using fasteners, thereby reducing assembly errors.

[0037] According to one embodiment of the present invention, the connecting section 133 is formed with an avoidance boss 1331 extending in the extension direction of the connecting plate 13 and protruding away from the lap plate 122. The design of the avoidance boss 1331 allows the connecting section 133 to avoid other body parts or structures when extending in the extension direction of the connecting plate 13, thereby avoiding interference and conflict. The spatial layout inside the vehicle body is optimized so that the various components can be arranged more compactly and efficiently, which helps to improve the overall performance and comfort of the vehicle. At the same time, the shape design of the avoidance boss 1331 protruding away from the lap plate 122 increases the rigidity of the connecting plate 13, can disperse stress, and reduce the deformation of the connecting section 133 when subjected to force, thereby improving the overall stability and durability of the vehicle body assembly 1.

[0038] According to one embodiment of the present invention, the width of the avoidance boss 1331 gradually decreases in the direction toward the first matching section 131 and / or toward the second matching section 132. Figure 1 As shown, the width of the avoidance boss 1331 gradually decreases in the direction toward the first mating section 131 and the second mating section 132. The width design of the avoidance boss 1331 makes the transition between the connecting section 133 and the first mating section 131 and the second mating section 132 more natural, reducing the possibility of stress concentration and structural mutation. It helps to enhance the continuity and integrity of the vehicle body structure and improve the rigidity and durability of the vehicle body. In addition, the width design of the avoidance boss 1331 can also avoid the first mounting hole 1311 and the second mounting hole 1321, which is convenient for the assembly of the connecting plate 13. The width design of the avoidance boss 1331 makes the cross-section of the entire connecting plate 13 in the extension direction change, so that the connecting plate 13 has better rigidity and higher structural strength.

[0039] According to one embodiment of the present invention, at least one wiring harness mounting hole 134 is provided on the connecting plate 13. Providing the wiring harness mounting hole 134 on the connecting plate 13 allows the wiring harness (such as electric wires, cables, etc.) inside the vehicle to pass through and be fixed in an orderly and neat manner. It helps to optimize the management of the wiring harness, reduce the disorder of the wiring harness, and improve the neatness and aesthetics of the interior of the vehicle. The wiring harness mounting hole 134 provides a clear positioning and fixing point for the assembler, making the installation process of the wiring harness faster and more accurate. By passing the wiring harness through the mounting hole on the connecting plate 13 and fixing it, the wiring harness can be protected from external mechanical damage, which helps to extend the service life of the wiring harness and reduce vehicle failures caused by damage to the wiring harness.

[0040] In some embodiments, the connecting plate 13 may also be provided with pins or holes for assembly or positioning with other vehicle body structures.

[0041] According to one embodiment of the present invention, a lap buckle 135 is formed on the first mating section 131 and / or the second mating section 132, and a positioning hole 112 that cooperates with the lap buckle 135 is formed on the side enclosure assembly 11 and / or the lap plate 122. The design of the lap buckle 135 and the positioning hole 112 provides a clear positioning point for the assembly process, which helps to reduce assembly errors. Workers can easily align the lap buckle 135 with the positioning hole 112 to ensure the precise alignment of the connecting parts, and then perform fixed assembly of the connecting plate 13. The cooperation between the lap buckle 135 and the positioning hole 112 makes the assembly process simpler and faster. Workers do not need to use fasteners such as bolts and nuts for pre-assembly, nor do they need to perform complicated pre-welding operations. They only need to align the lap buckle 135 with the positioning hole 112 and gently push it in to achieve the positioning of the connecting plate 13, which greatly improves assembly efficiency and shortens the production cycle.

[0042] According to one embodiment of the present invention, the connecting plate 13 is inclined, and the angle between the connecting plate 13 and the horizontal plane where the bottom of the vehicle body is located is α, and it satisfies 40°≤α≤50°. The inclined setting of the connecting plate 13 can more effectively utilize the space inside the vehicle body. When the angle α is in the range of 40° to 50°, the connecting plate 13 will not be too steep to occupy the upper space, nor will it be too flat to waste the lower space. It is helpful to optimize the layout of the vehicle body structure and improve space utilization. In actual assembly, the value of α can be preferably set to 45°. At this time, after the connecting plate 13 is connected, it can form a structure similar to an isosceles right triangle with the side panel assembly 11 and the lap plate 122, which is more stable as a whole, further improving the stability of the vehicle body assembly 1.

[0043] The vehicle according to the present invention will be briefly described below.

[0044] The vehicle according to the present invention includes the body assembly 1 in the above embodiment. Since the vehicle according to the present invention is provided with the body assembly 1 in the above embodiment, the body assembly 1 can improve the stability of the connection between the side panel assembly 11 and the floor assembly 12 through the connecting plate 13, thereby improving the rigidity of the body assembly 1, reducing the yaw and shake of the vehicle when driving at high speed or turning, and improving the comfort and safety of the vehicle.
