[0037] Reference Figures 1 to 4 The diagram shows a schematic of a side reinforcement plate structure 10 according to an embodiment of this application. Specifically, it may include: an A-pillar reinforcement section 11, a side beam reinforcement section 12, a B-pillar reinforcement section 13, and a sill reinforcement section 14. The A-pillar reinforcement section 11 is connected to the sill reinforcement section 14, the side beam reinforcement section 12 is connected to the A-pillar reinforcement section 11, and the B-pillar reinforcement section 13 is connected between the side beam reinforcement section 12 and the sill reinforcement section 14. The A-pillar reinforcement section 11, the side beam reinforcement section 12, the B-pillar reinforcement section 13, and the sill reinforcement section 14 enclose and form a closed-loop reinforcement structure. The A-pillar reinforcement section 11, the side beam reinforcement section 12, the B-pillar reinforcement section 13, and the sill reinforcement section 14 have hollow cavities.

[0038] In this embodiment, the A-pillar reinforcement section 11, the side beam reinforcement section 12, the B-pillar reinforcement section 13, and the sill reinforcement section 14 are connected end-to-end to form a closed-loop structure. This ensures good force transmission continuity and structural stability when the side reinforcement plate structure 10 is subjected to stress due to vehicle vibration, thus improving the force transmission effect. Furthermore, the inclusion of cavities in the A-pillar reinforcement section 11, the side beam reinforcement section 12, the B-pillar reinforcement section 13, and the sill reinforcement section 14 enhances the structural strength and deformation resistance of each component compared to existing sheet metal structures, thereby improving structural stability. Moreover, the closed-loop side reinforcement structure provides a closed-loop protection structure for the passenger compartment, improving the vehicle's collision avoidance and safety performance, resulting in better overall vehicle performance. Compared to existing technologies, the side reinforcement plate structure 10 of this application has fewer components, reducing the complexity of component connections and simplifying the manufacturing process. This avoids the need to use multiple patch panels to locally reinforce the overall structure, improves the force transmission effect of the side reinforcement panel structure 10, and reduces the risk of structural instability.

[0039] Specifically, in this embodiment, the sill reinforcement section 14 is positioned near the bottom of the vehicle sill and extends along the length of the vehicle; the A-pillar reinforcement section 11 is positioned near the A-pillar of the vehicle and extends along the height of the vehicle; the B-pillar reinforcement section 13 is positioned near the B-pillar of the vehicle and extends along the height of the vehicle; the side beam reinforcement section 12 can be an upper side beam reinforcement section 12, positioned near the top of the vehicle, and the side beam reinforcement section 12 connects the ends of the A-pillar reinforcement section 11 and the B-pillar reinforcement section 13 away from the sill reinforcement section 14. That is, the A-pillar reinforcement section 11 and the B-pillar reinforcement section 13 are spaced apart, and the sill reinforcement section 14 and the side beam reinforcement section 12 are spaced apart, forming a closed ring structure similar to a rectangle or trapezoid, which gives the side reinforcement structure a better force transmission effect and structural stability.

[0040] In this embodiment, optionally, the A-pillar reinforcement section 11, the side beam reinforcement section 12, the B-pillar reinforcement section 13, and the sill reinforcement section 14 can be manufactured using a hot air expansion process, giving each component good structural strength. Specifically, the hot air expansion forming process uses induction heating to heat the blank to be processed, such as pipes or plates, to a preset temperature, giving the pipes or plates high deformation capacity and low deformation resistance. Then, the blank is deformed using high-pressure gas, and subsequently, the gas pressure is increased for shaping to obtain the component of the desired shape. For example, the blank to be processed can first be placed in a mold and sealed, then high-pressure gas is introduced and subjected to appropriate pressure. The blank to be processed expands and deforms under the action of high-pressure gas, and then the gas pressure is increased for shaping to obtain the desired component. In addition, other processes can be used to process the A-pillar reinforcement section 11, the side beam reinforcement section 12, the B-pillar reinforcement section 13, and the sill reinforcement section 14 as needed. This embodiment does not limit the specific processing method.

[0041] In this embodiment, for example, the connections between the A-pillar reinforcement section 11 and the side beam reinforcement section 12, between the side beam reinforcement section 12 and the B-pillar reinforcement section 13, between the B-pillar reinforcement section 13 and the sill reinforcement section 14, and between the sill reinforcement section 14 and the A-pillar reinforcement section 11 can be achieved using arc welding or laser welding, resulting in a relatively stable, reliable, and smooth connection. This forms an integral thermal expansion reinforcement ring, making the side wall reinforcement plate structure 10 a relatively smooth ring structure, and also forming a closed protective structure for the passenger compartment, thus enhancing the overall crashworthiness. Simulation tests show that the closed-loop side wall reinforcement structure in this application can meet the 25% small-angle offset collision performance, giving the vehicle better crashworthiness and safety.

[0042] For example, in this embodiment of the application, the A-pillar reinforcement section 11, the side beam reinforcement section 12, the B-pillar reinforcement section 13, and the sill reinforcement section 14 are interconnected, forming seam lines between each pair. The positions and number of these seam lines can be adjusted according to actual performance requirements. That is, the number of segments in the side reinforcement plate structure 10 can be any value between 2 and 6 reinforcement sections, such as... Figures 1 to 3 The illustration shows a side reinforcement plate structure 10 with five segments. However, the side reinforcement plate structure 10 can also be configured with two segments, four segments, six segments, etc., and this embodiment does not impose any limitations on this.

[0043] In this embodiment, the tensile strength of the A-column reinforcement section 11, the side beam reinforcement section 12, the B-column reinforcement section 13, and the sill reinforcement section 14 can be any value between 1000 MPa and 2000 MPa, such as 1000 MPa, 1500 MPa, 1800 MPa, or 2000 MPa, etc. This embodiment does not limit the specific tensile strength of each of the above-mentioned structural sections. Furthermore, the tensile strengths of the A-column reinforcement section 11, the side beam reinforcement section 12, the B-column reinforcement section 13, and the sill reinforcement section 14 can be the same or different; this embodiment also does not limit this.

[0044] Optionally, in this embodiment, the A-pillar reinforcement section 11, the side beam reinforcement section 12, the B-pillar reinforcement section 13, and the sill reinforcement section 14 are variable diameter pipes. That is, the cross-sectional dimensions of the cavities of the A-pillar reinforcement section 11, the side beam reinforcement section 12, the B-pillar reinforcement section 13, and the sill reinforcement section 14 are variable, so that the cross-sectional sizes inside each cavity can be different. Thus, the cross-sectional changes of each reinforcement section along the X-direction (i.e., the length direction of the vehicle), Y-direction (i.e., the width direction of the vehicle), and Z-direction (i.e., the height direction of the vehicle) of the A-pillar reinforcement section 11, the side beam reinforcement section 12, the B-pillar reinforcement section 13, and the sill reinforcement section 14 can be set according to the cavity size and collision performance requirements, so that the side reinforcement plate structure 10 has better anti-collision performance and achieves better lightweight design.

[0045] Optionally, in this embodiment, the B-pillar reinforcement section 13 includes a first reinforcement section 131 and a second reinforcement section 132; the first reinforcement section 131 is connected to the side beam reinforcement section 12, and the second reinforcement section 132 is connected between the first reinforcement section 131 and the sill reinforcement section 14. This divides the B-pillar reinforcement section 13 into a two-section structure, with the first reinforcement section 131 connecting the B-pillar reinforcement section 13 to the side beam reinforcement section 12 above the vehicle, and the second reinforcement section 132 connecting the B-pillar reinforcement section 13 to the sill reinforcement section 14 below the vehicle, facilitating flexible layout based on actual space.

[0046] Optionally, in this embodiment, the second reinforcing section 132 is provided with a plurality of spaced-apart contraction ribs 133. The second reinforcing section 132 includes a first end near the first reinforcing section 131 and a second end near the sill reinforcing section 14. Along the direction from the first end to the second end, the dimensions of the plurality of contraction ribs 133 increase sequentially, and the dimensions include at least one of depth and width. In this way, the second reinforcing section 132 can absorb energy through contraction of the contraction ribs 133, effectively absorbing the vibration generated by the vehicle and dispersing the energy, reducing the damage of external impacts to the vehicle side structure, improving its seismic and impact resistance, giving the vehicle side structure better safety and reliability, extending its service life, and reducing maintenance costs.

[0047] In practical applications, when occupants are inside a vehicle, the upper first reinforcing section 131 is closer to the human body, while the lower second reinforcing section 132 is farther away. Therefore, a crumple rib 133 is provided in the second reinforcing section 132. When the vehicle vibrates or is impacted, the second reinforcing section 132 is more likely to crumple and absorb energy than the first reinforcing section 131, resulting in less deformation of the first reinforcing section 131 closer to the human body. Thus, during vehicle safety performance testing with a dummy, the intrusion of the upper first reinforcing section 131 near the dummy during side collisions is reduced, improving vehicle safety performance.

[0048] Furthermore, in this embodiment, along the direction from the first end to the second end of the second reinforcing segment 132, the dimensions of a plurality of collapsing ribs 133 on the second reinforcing segment 132 are progressively increased, and the dimensions include at least one of depth and width. This results in a gradually enhanced collapsing energy absorption effect of the second reinforcing segment 132 along the direction from the first end to the second end, and its deformation also gradually increases. That is, the deformation of the side of the second reinforcing segment 132 closest to the first reinforcing segment 131 is smaller, reducing the impact of the second reinforcing segment 132 on the first reinforcing segment 131 during collapsing energy absorption, thus giving the first reinforcing segment 131 better stability.

[0049] For example, in an embodiment of this application, multiple contraction ribs 133 can form a matrix-like contraction-inducing structure. Figure 4 The diagram illustrates a matrix containing three contraction ribs 133, where each matrix includes two contraction ribs 133 whose dimensions increase sequentially from top to bottom. Alternatively, it can be configured with two or four contraction rib matrices, etc., depending on actual needs. This application embodiment does not limit the specific number or arrangement of the contraction ribs 133.

[0050] In this embodiment, for example, the tensile strength of the first reinforcing segment 131 can be any value between 1000 MPa and 2000 MPa, such as 1000 MPa, 1500 MPa, 1800 MPa, or 2000 MPa, etc. This embodiment does not limit the specific tensile strength of the first reinforcing segment 131. The second reinforcing segment 132 is provided with a crumple rib 133 for energy absorption and crumple in the event of a collision with the side of the vehicle. Therefore, its tensile strength can be set to any value between 300 MPa and 1000 MPa, such as 300 MPa, 500 MPa, 800 MPa, or 1000 MPa, etc. This embodiment does not limit the specific tensile strength of the second reinforcing segment. Furthermore, the tensile strengths of the first reinforcing segment 131 and the second reinforcing segment 132 can be the same or different, and this embodiment does not limit this as well.

[0051] Optionally, in this embodiment, the constriction rib 133 has grooves, and along the direction from the first end to the second end, the width of the grooves of the plurality of constriction ribs 133 increases sequentially, and / or, the depth of the grooves of the plurality of constriction ribs 133 increases sequentially. Thus, by setting the width of the grooves of the plurality of constriction ribs 133 to increase sequentially, the size of the constriction rib 133 along the first end to the second segment increases sequentially, thereby gradually enhancing its constriction energy absorption effect. Alternatively, by setting the depth of the grooves of the plurality of constriction ribs 133 to increase sequentially, the size of the constriction rib 133 along the first end to the second segment increases sequentially, thereby gradually enhancing its constriction energy absorption effect. Furthermore, by setting both the width and depth of the grooves of the plurality of constriction ribs 133 to increase sequentially, the size of the constriction rib 133 along the first end to the second segment increases sequentially, resulting in an even better effect of gradually enhancing its constriction energy absorption. The specific arrangement of the plurality of constriction ribs 133 in this embodiment is not limited.

[0052] For example, in the embodiments of this application, the depth of the groove can be set to any value between 3mm and 10mm, such as 3mm, 5mm, 8mm or 10mm, etc. The specific depth value of the groove of the multiple contraction ribs 133 is not limited in the embodiments of this application.

[0053] Optionally, in this embodiment, the side reinforcement plate structure 10 includes a first side 15 and a second side 16 disposed opposite to each other. The first side 15 is used to connect to the vehicle body hinge, and the side reinforcement plate structure 10 also includes a hinge reinforcement plate 17 connected to the first side 15. Thus, integrating the hinge reinforcement plate 17 on the first side 15 of the side reinforcement plate structure 10 facilitates a reinforced connection between the side reinforcement plate structure 10 and the vehicle's hinge structure.

[0054] For example, in this embodiment of the application, the number of hinge reinforcing plates 17 can be multiple, and the multiple hinge reinforcing plates 17 are arranged at intervals, such as... Figure 2 The example shown has four hinge reinforcement plates 17. However, the number of hinge reinforcement plates 17 can be three, five, or six, etc., and can be set according to actual needs. This embodiment does not limit the specific number of hinge reinforcement plates 17.

[0055] Optionally, in this embodiment, the second side 16 of the side reinforcement plate structure 10 is used to connect the inner side panel 20. The side reinforcement plate structure 10 also includes a connecting plate 18 connected to the second side 16. Thus, the connecting plate 18 on the second side 16 of the side reinforcement plate structure 10, used to connect the inner side panel 20, facilitates a reinforced connection between the side reinforcement plate structure 10 and the inner side panel 20.

[0056] For example, in this embodiment of the application, the number of connecting plates 18 can also be multiple, and the multiple connecting plates 18 are arranged at intervals, such as... Figure 3 The example shown has 7 connecting plates 18. However, the number of connecting plates 18 can be 5, 6, or 8, etc., and can be set according to actual needs. This embodiment of the application does not limit the specific number of connecting plates 18.

[0057] In summary, the side reinforcement plate structure described in the embodiments of this application can include at least the following advantages:

[0058] In this embodiment, the side panel reinforcement structure includes: an A-pillar reinforcement section, a side beam reinforcement section, a B-pillar reinforcement section, and a sill reinforcement section; the A-pillar reinforcement section is connected to the sill reinforcement section, the side beam reinforcement section is connected to the A-pillar reinforcement section, and the B-pillar reinforcement section is connected between the side beam reinforcement section and the sill reinforcement section; the A-pillar reinforcement section, the side beam reinforcement section, the B-pillar reinforcement section, and the sill reinforcement section form a closed-loop reinforcement structure; the A-pillar reinforcement section, the side beam reinforcement section, the B-pillar reinforcement section, and the sill reinforcement section have hollow cavities. That is, the A-pillar reinforcement section, the side beam reinforcement section, the B-pillar reinforcement section, and the sill reinforcement section are connected end-to-end in sequence to form a closed-loop structure. Thus, when the side panel reinforcement structure is subjected to stress due to vehicle vibration, the closed-loop side panel reinforcement structure can have good force transmission continuity and good structural stability, improving the force transmission effect. Furthermore, the A-pillar reinforcement section, the side beam reinforcement section, the B-pillar reinforcement section, and the sill reinforcement section all have hollow cavities, which improves the structural strength and deformation resistance of each component, thereby enhancing structural stability. Moreover, the closed-loop side reinforcement structure forms a closed-loop protection structure for the passenger compartment, improving the vehicle's collision avoidance and safety performance, resulting in better overall vehicle performance. Compared to existing technologies, the side reinforcement plate structure of this application has fewer components, reducing the complexity of component connections and simplifying the manufacturing process. It avoids the need for multiple patch plates to locally reinforce the overall structure, improving the force transmission effect of the side reinforcement plate structure and reducing the risk of structural instability.

[0059] Reference Figures 5 to 6 The diagram shows a structural schematic of a side panel assembly according to an embodiment of this application. The side panel assembly includes a side panel 20 and a side reinforcement plate structure 10; the side reinforcement plate structure 10 is connected to the side panel 20.

[0060] Specifically, in this embodiment, the side panel reinforcement structure 10 can be connected to the inner side panel 20 near the vehicle compartment along the width direction of the vehicle. For example, the closed-loop side panel reinforcement structure 10 can be spot-welded to the inner side panel 20, resulting in good connection reliability and stability.

[0061] The side panel assembly described in this application embodiment may include at least the following advantages:

[0062] In this embodiment, the side panel assembly includes a side panel and a side reinforcement plate structure; the side reinforcement plate structure is connected to the side panel and includes: an A-pillar reinforcement section, a side beam reinforcement section, a B-pillar reinforcement section, and a sill reinforcement section; the A-pillar reinforcement section is connected to the sill reinforcement section, the side beam reinforcement section is connected to the A-pillar reinforcement section, and the B-pillar reinforcement section is connected between the side beam reinforcement section and the sill reinforcement section; the A-pillar reinforcement section, the side beam reinforcement section, the B-pillar reinforcement section, and the sill reinforcement section form a closed-loop reinforcement structure; the A-pillar reinforcement section, the side beam reinforcement section, the B-pillar reinforcement section, and the sill reinforcement section have hollow cavities. In other words, the A-pillar reinforcement section, the side beam reinforcement section, the B-pillar reinforcement section, and the sill reinforcement section are connected end-to-end to form a closed-loop structure. This ensures good force transmission continuity and structural stability when the side reinforcement structure is subjected to stress due to vehicle vibration, thus improving force transmission efficiency. Furthermore, the hollow cavities of the A-pillar reinforcement section, side beam reinforcement section, B-pillar reinforcement section, and sill reinforcement section enhance the structural strength and deformation resistance of each component, improving structural stability. Moreover, the closed-loop side reinforcement structure forms a closed-loop protection structure for the passenger compartment, improving the vehicle's collision avoidance and safety performance, resulting in better overall vehicle performance. Compared to existing technologies, the side reinforcement structure of this application has fewer components, reducing the complexity of component connections and the complexity of the manufacturing process. It avoids the need for multiple patch panels to locally reinforce the overall structure, improving the force transmission effect of the side reinforcement structure and reducing the risk of structural instability.

[0064] The vehicle body structure described in this application embodiment may include at least the following advantages:

[0065] In this embodiment, the vehicle body structure includes the side inner panel assembly, which includes the side inner panel and the side reinforcement plate structure. The side reinforcement plate structure is connected to the side inner panel and includes an A-pillar reinforcement section, a side beam reinforcement section, a B-pillar reinforcement section, and a sill reinforcement section. The A-pillar reinforcement section is connected to the sill reinforcement section, the side beam reinforcement section is connected to the A-pillar reinforcement section, and the B-pillar reinforcement section is connected between the side beam reinforcement section and the sill reinforcement section. The A-pillar reinforcement section, the side beam reinforcement section, the B-pillar reinforcement section, and the sill reinforcement section form a closed-loop reinforcement structure. The A-pillar reinforcement section, the side beam reinforcement section, the B-pillar reinforcement section, and the sill reinforcement section have hollow cavities. In other words, the A-pillar reinforcement section, the side beam reinforcement section, the B-pillar reinforcement section, and the sill reinforcement section are connected end-to-end to form a closed-loop structure. This ensures good force transmission continuity and structural stability when the side reinforcement structure is subjected to stress due to vehicle vibration, thus improving force transmission efficiency. Furthermore, the hollow cavities of the A-pillar reinforcement section, side beam reinforcement section, B-pillar reinforcement section, and sill reinforcement section enhance the structural strength and deformation resistance of each component, improving structural stability. Moreover, the closed-loop side reinforcement structure forms a closed-loop protection structure for the passenger compartment, improving the vehicle's collision avoidance and safety performance, resulting in better overall vehicle performance. Compared to existing technologies, the side reinforcement structure of this application has fewer components, reducing the complexity of component connections and the complexity of the manufacturing process. It avoids the need for multiple patch panels to locally reinforce the overall structure, improving the force transmission effect of the side reinforcement structure and reducing the risk of structural instability.
