Description

Technical Field

[0001] This invention relates to the field of vehicles, and more particularly to a vehicle body assembly and a vehicle. Background Technology

[0002] With the booming development of the automotive industry, the domestic SUV market has gradually emerged. Fastback SUVs combine the high body of ordinary SUVs with the smooth roofline of sedans, offering both sportiness and practicality, and providing consumers with more choices. However, the fastback design results in a relatively high center of gravity, leading to noticeable Y-axis yaw and vibration at high speeds, resulting in poor comfort. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of this invention is to provide a vehicle body assembly. According to the invention, the vehicle body assembly connects the side panel assembly to the overlapping plate fitted to the wheel arch via a connecting plate, improving the stability of the connection between the side panel assembly and the floor assembly. This effectively enhances the rigidity and stability of the overall structure after the side panel assembly and floor assembly are joined, reducing Y-axis yaw and vibration of the vehicle body, and improving vehicle comfort and driving experience.

[0004] The present invention also proposes a vehicle including the above-described vehicle body assembly.

[0005] The vehicle body assembly according to the present invention includes a side panel assembly, a floor assembly, and a connecting plate. The floor assembly has wheel covers and an overlapping plate that fits the wheel covers. One end of the overlapping plate is connected to the bottom wall of the floor assembly, and the other end of the overlapping plate extends to the side panel assembly and connects the side panel assembly to the floor assembly. One end of the connecting plate is connected to the side panel assembly, and the other end of the connecting plate is connected to the overlapping plate.

[0006] According to the present invention, the vehicle body assembly includes a floor assembly on which a wheel cover is formed. A side panel assembly is provided on one side edge of the wheel cover. During assembly, the side panel assembly and the floor assembly can be spliced ​​together. Due to the shape limitation of the wheel cover, the spliced ​​floor assembly and side panel assembly form a ring-shaped structure. The overlapping plate fits the wheel cover, and one end of the overlapping plate extends along the surface of the wheel cover to the floor assembly, making the connection between the floor assembly and the wheel cover more stable. The other end of the overlapping plate can fit at least a part of the side panel assembly, realizing the connection between the side panel assembly, the wheel cover, and the floor assembly. The overlapping plate makes the floor assembly and the side panel assembly spliced ​​into a whole, improving the stability of the connection between the side panel assembly and the floor assembly. At this point, one end of the connecting plate is connected to the overlapping plate, and the other end of the connecting plate is connected to the side panel assembly. This reduces the looseness between the side panel assembly and the floor assembly, effectively enhancing the rigidity and stability of the overall structure after the side panel assembly and the floor assembly are spliced ​​together. This reduces the Y-axis yaw and vibration of the vehicle body, improving vehicle comfort and driving experience.

[0007] According to one embodiment of the present invention, the overlapping plate has an arcuate segment that fits at least a portion of the surface of the wheel cover, and the connecting plate is spaced apart from the arcuate segment.

[0008] According to one embodiment of the present invention, the connecting plate includes: a first mating section, a second mating section, and a connecting section, wherein the first mating section has a first mating area that fits against the side panel assembly; at least a portion of the second mating section has a second mating area that fits against the overlapping plate; the connecting section connects the first mating section and the second mating section, and the connecting section is spaced apart from the arc-shaped section.

[0009] According to one embodiment of the present invention, a first mounting hole is formed in the first mating area, and a first mating hole corresponding to the first mounting hole is formed on the side assembly; a second mounting hole is formed in the second mating area, and a second mating hole corresponding to the second mounting hole is formed on the overlapping plate.

[0010] According to one embodiment of the present invention, the connecting segment is formed with a relief boss that extends in the extending direction of the connecting plate and protrudes away from the overlapping plate.

[0011] According to one embodiment of the present invention, the width of the clearance boss gradually decreases in the direction toward the first mating section and / or toward the second mating section.

[0012] According to one embodiment of the present invention, the connecting plate is provided with at least one wire harness mounting hole.

[0013] According to one embodiment of the present invention, a snap fastener is formed on the first mating section and / or the second mating section, and a positioning hole that mates with the snap fastener is formed on the side panel assembly and / or the snap plate.

[0014] According to one embodiment of the present invention, the connecting plate is inclined, and the angle between the connecting plate and the horizontal plane where the bottom of the vehicle body is located is α, and satisfies 40°≤α≤50°.

[0015] The vehicle according to the present invention is briefly described below.

[0016] The vehicle according to the present invention includes the body assembly of the above embodiments. Since the vehicle according to the present invention is provided with the body assembly of the above embodiments, the body assembly can improve the stability of the connection between the side assembly and the floor assembly through the connecting plate, thereby improving the rigidity of the body assembly, reducing the yaw and sway of the vehicle when driving at high speed or turning, and improving the comfort and safety of the vehicle.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] With the booming development of the automotive industry, the domestic SUV market has gradually emerged. Fastback SUVs combine the high body of ordinary SUVs with the smooth roofline of sedans, offering both sportiness and practicality, and providing consumers with more choices. However, the fastback design results in a relatively high center of gravity, leading to noticeable Y-axis yaw and vibration at high speeds, resulting in poor comfort.

[0030] The following is for reference. Figures 1-4 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 arch 121 and an overlapping plate 122 that fits the wheel arch 121 are formed on the floor assembly 12. One end of the overlapping plate 122 is connected to the bottom wall of the floor assembly 12, and the other end of the overlapping plate 122 extends to the side panel assembly 11 and connects the side panel assembly 11 and 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 overlapping plate 122.

[0032] According to the present invention, the vehicle body assembly 1 is provided with a floor assembly 12, on which a wheel cover 121 is formed. 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 ​​together. Due to the shape limitation of the wheel cover 121, the spliced ​​floor assembly 12 and the side panel assembly 11 will form a ring-shaped structure. The overlapping plate 122 fits the wheel cover 121, and one end of the overlapping plate 122 extends along the surface of the wheel cover 121 to the floor assembly 12, making the connection between the floor assembly 12 and the wheel cover 121 more stable. The other end of the overlapping plate 122 can fit at least a part of the side panel assembly 11, realizing the connection between the side panel assembly 11, the wheel cover 121, and the floor assembly 12. The arrangement of the overlapping plate 122 makes the floor assembly 12 and the side panel assembly 11 spliced ​​into a whole, 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 overlapping plate 122, and the other end of the connecting plate 13 is connected to the side assembly 11. This can reduce the looseness between the side assembly 11 and the floor assembly 12, effectively enhance the rigidity and stability of the overall structure after the side assembly 11 and the floor assembly 12 are spliced, reduce the Y-axis yaw 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 arcuate segment 1221 is formed on the overlapping plate 122, which is in contact with at least a portion of the surface of the wheel arch 121, and the connecting plate 13 is spaced apart from the arcuate segment 1221. The arcuate segment 1221 formed on the overlapping plate 122, which is in contact with at least a portion of the surface of the wheel arch 121, increases the contact area between the overlapping plate 122 and the wheel arch 121, and can form a good transition between the wheel arch 121 and the side panel assembly 11, thereby enhancing the stability of the connection between the side panel assembly 11 and the wheel arch 121, helping to reduce vibration and noise caused by uneven road surfaces or turning during vehicle operation, 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, which can form a stable triangular area between the connecting plate 13 and the arc segment 1221. This improves the connection stability between the connecting plate 13, the overlapping plate 122, and the side assembly 11, thereby improving the rigidity of the body assembly 1, reducing vehicle vibration and yaw, and improving vehicle safety.

[0034] According to one embodiment of the present invention, the connecting plate 13 includes: a first mating section 131, a second mating section 132, and a connecting section 133. The first mating section 131 has a first mating area that fits against the side panel assembly 11; at least a portion of the second mating section 132 fits against the overlapping plate 122; the connecting section 133 connects the first mating section 131 and the second mating section 132, and the connecting section 133 is spaced apart from the arcuate section 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. This 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 assembly 11 and the overlapping 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 assembly 11, and the second mating area on the second mating section 132 fits with the overlapping plate 122. This multi-point connection method allows the vehicle body assembly 1 to distribute stress more evenly when under load, improving overall strength and durability. Simultaneously, the segmented design of the connecting plate 13 makes the assembly process more flexible and efficient. Each mating section has a clearly defined mating area, making adjustment and positioning easier during assembly and reducing assembly errors. The spacing between the connecting section 133 and the arc-shaped section 1221 also provides more assembly space, facilitating worker operation and improving assembly efficiency.

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

[0037] According to one embodiment of the present invention, the connecting segment 133 is formed with a clearance boss 1331 extending in the extending direction of the connecting plate 13 and protruding away from the overlapping plate 122. The design of the clearance boss 1331 allows the connecting segment 133 to avoid other body parts or structures when extending in the extending direction of the connecting plate 13, thereby avoiding interference and conflict. This optimizes the spatial layout inside the vehicle body, allowing for a more compact and efficient arrangement of various components, which helps to improve the overall performance and comfort of the vehicle. At the same time, the shape design of the clearance boss 1331 protruding away from the overlapping plate 122 increases the rigidity of the connecting plate 13, which can distribute stress and reduce the deformation of the connecting segment 133 under stress, thereby improving the overall stability and durability of the vehicle body assembly 1.

[0038] According to one embodiment of the invention, the width of the clearance boss 1331 gradually decreases in the direction toward the first mating section 131 and / or toward the second mating section 132. For example... Figure 1 As shown, the width of the clearance boss 1331 gradually decreases in the direction towards the first mating section 131 and the second mating section 132. This width design of the clearance 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 abrupt changes. This helps to enhance the continuity and integrity of the vehicle body structure, improving the rigidity and durability of the vehicle body. Furthermore, the width design of the clearance boss 1331 also avoids the first mounting hole 1311 and the second mounting hole 1321, facilitating the assembly of the connecting plate 13. The width design of the clearance boss 1331 makes the cross-section of the entire connecting plate 13 vary in the extending direction, resulting in better rigidity and higher structural strength.

[0039] According to one embodiment of the present invention, the connecting plate 13 is provided with at least one wire harness mounting hole 134. Providing the wire harness mounting hole 134 on the connecting plate 13 allows wire harnesses (such as wires, cables, etc.) inside the vehicle to pass through and be secured in an orderly and neat manner. This helps optimize wire harness management, reduce wire harness clutter, and improve the cleanliness and aesthetics of the vehicle interior. The wire harness mounting hole 134 provides assembly workers with clear positioning and fixing points, making the wire harness installation process faster and more accurate. By passing the wire harness through the mounting hole on the connecting plate 13 and securing it, the wire harness can be protected from external mechanical damage, helping to extend the service life of the wire harness and reduce vehicle malfunctions caused by wire harness damage.

[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 snap fastener 135 is formed on the first mating section 131 and / or the second mating section 132, and a positioning hole 112 is formed on the side assembly 11 and / or the lap plate 122 to mate with the snap fastener 135. The design of the snap fastener 135 and the positioning hole 112 provides clear positioning points for the assembly process, which helps to reduce assembly errors. Workers can easily align the snap fastener 135 with the positioning hole 112 to ensure precise alignment of the connecting parts before fixing the connecting plate 13. The mating of the snap fastener 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 complex pre-welding operations. They only need to align the snap fastener 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, satisfying 40°≤α≤50°. The inclined arrangement of the connecting plate 13 can make more efficient use of the space inside the vehicle body. When the angle α is in the range of 40° to 50°, the connecting plate 13 is neither too steep and occupying the upper space, nor too gentle and wasting the lower space. This helps to optimize the layout of the vehicle body structure and improve space utilization. In actual assembly, the value of α can preferably be 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 assembly 11 and the overlapping plate 122, which is more stable overall and further improves the stability of the vehicle body assembly 1.
