Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a vehicle body side panel and a vehicle. Background Technology

[0002] Currently, when a vehicle's sidewalls are involved in a side collision, the B-pillar and sill beam are usually left to withstand the collision load alone. The B-pillar lacks a direct load transfer and energy release channel to the vehicle's chassis frame, subframe, or battery pack and other bottom load-bearing components. A large amount of impact force is concentrated in the middle section of the B-pillar, causing the B-pillar to undergo significant inward plastic deformation, which severely compresses the space inside the passenger compartment. Utility Model Content

[0003] This application provides a vehicle body side panel and a vehicle that can provide multiple collision force venting paths for the B-pillar, reducing the deformation of the B-pillar.

[0004] To achieve the above objectives, the main technical solutions adopted in this application include: Firstly, this application provides a vehicle side panel, including a B-pillar and a C-pillar, an upper beam of the C-pillar, a sill beam, at least one reinforcing tube beam, and multiple connecting tube beams. The upper beam of the C-pillar connects the upper ends of the B-pillar and the upper ends of the C-pillar. The sill beam connects the lower ends of the B-pillar and the lower ends of the C-pillar. At least one reinforcing tube beam, along the vertical direction of the vehicle, is disposed between the lower beam of the C-pillar and the sill beam. The reinforcing tube beam extends along the longitudinal direction of the vehicle and connects the B-pillar and the C-pillar. The upper beam of the C-pillar and the reinforcing tube beam form a window mounting area. Along the longitudinal direction of the vehicle, multiple connecting tube beams are spaced apart. Along the vertical direction of the vehicle, one end of each connecting tube beam is connected to the reinforcing tube beam, and the other end is connected to the sill beam. When the B-pillar is impacted, the impact force on the B-pillar can be transmitted along the longitudinal and vertical directions of the vehicle, thereby releasing the impact force on the B-pillar and reducing the deformation of the B-pillar.

[0005] Optionally, the plurality of connecting tube beams includes a first connecting tube beam adjacent to the B-pillar; the vehicle side panel also includes at least one first connector, which is connected between the B-pillar and the first connecting tube beam. The first connector, connecting the B-pillar and the first connecting tube beam, not only enhances the strength and rigidity of the first connecting tube beam but also directly transfers the impact force received by the B-pillar to the first connecting tube beam, thus dissipating the impact force on the B-pillar.

[0006] Optionally, at least one second connector is provided between two adjacent connecting pipe beams. The second connector connecting two adjacent connecting pipe beams can improve the strength and stiffness of the connecting pipe beams and reduce their deformation.

[0007] Optionally, both the first connector and the second connector are constructed in multiples. Along the front-rear direction of the vehicle, each first connector and its corresponding second connector are constructed as an integral molded part, which can further improve the connection strength of the first connecting tube beam and the second connecting tube beam, and at the same time form a force transmission path along the front-rear direction of the vehicle, further providing a reliable path for the release of the collision force received by the B-pillar.

[0008] Optionally, both the reinforcing tube beam and the connecting tube beam are constructed as hollow tubes. The geometric and mechanical properties of hollow tubes are utilized to improve torsional stiffness while reducing the weight of the vehicle body side panels, thus achieving lightweighting of the vehicle body side panels.

[0009] Optionally, the system also includes a first reinforcing plate, which is connected to the upper side beam of the C-pillar and the reinforcing tube beam on the side near the C-pillar. The first reinforcing plate extends along the vertical direction of the vehicle, which can improve the connection strength between the upper side beam of the C-pillar and the reinforcing tube beam, thereby improving the strength and rigidity of the vehicle body side panel and enhancing the collision avoidance performance of the vehicle body side panel.

[0010] Optionally, the B-pillar includes a body and a B-pillar reinforcing tube. The B-pillar reinforcing tube is disposed on the body and both the body and the B-pillar reinforcing tube are connected to the reinforcing tube beam. Both the body and the B-pillar reinforcing tube are connected to the upper side beam of the C-pillar. The B-pillar reinforcing tube is constructed as an arc-shaped component protruding away from the interior of the vehicle body. The B-pillar reinforcing tube extends along the vertical direction of the vehicle and is constructed as an outwardly protruding arc-shaped structure, giving the B-pillar a high section bending resistance coefficient, thereby resisting the bending moment generated by the collision in a side impact.

[0011] Optionally, along the vertical direction of the vehicle, the main body includes a connected intermediate area and a lower reinforcing area, and along the horizontal direction of the vehicle, the size of the intermediate area is smaller than the size of the lower reinforcing area. When the vehicle body is subjected to a side impact, the lower reinforcing area increases the crumple zone of the B-pillar, thereby reducing the amount of deformation of the B-pillar into the vehicle body and reducing excessive bending or even breakage of the B-pillar.

[0012] Optionally, the C-pillar includes a first beam, a second beam, and a connecting beam. Along the vertical direction of the vehicle, the first beam and the second beam are spaced apart, and the connecting beam connects the first beam and the second beam. The first beam connects to the upper beam of the C-pillar, and the second beam connects to the reinforcing tube beam. The vehicle side panel also includes a first reinforcing beam, which is located between the first beam and the second beam and is angled to the vertical direction of the vehicle. The first reinforcing beam connects between the first beam and the second beam, and along the longitudinal direction of the vehicle, one end of the first reinforcing beam connected to the first beam is located in front of the end connected to the second beam, such that the first reinforcing plate, the second beam, and the first reinforcing beam form a triangle, and the first beam, the connecting beam, and the first reinforcing beam also form a triangle, thereby improving the compressive strength of the upper side of the vehicle side panel and reducing deformation of the upper side of the vehicle side panel.

[0013] Secondly, this application provides a vehicle including the body side panel described in any of the above embodiments. The vehicle of this application has the beneficial effects of the body side panel described in any of the above embodiments.

[0014] This application has at least the following beneficial effects: In this application, the B-pillar and C-pillar are connected by the upper side beam of the C-pillar and at least one reinforcing tube beam, thereby realizing multiple transmission paths for transmitting the collision force received by the B-pillar to the rear. Then, the collision force is transmitted downward by connecting the reinforcing tube beam and the sill beam, thereby achieving the diversion of the collision force received by the B-pillar, reducing the deformation of the B-pillar, and thus reducing the occupancy of the B-pillar in the passenger compartment space.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0020] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0021] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components.

[0022] In this application, "multiple" means two or more (including two).

[0023] Currently, the side panel assembly of the vehicle body has the following shortcomings in meeting the requirements for side impact and overall vehicle lightweighting: 1. Inefficient energy absorption and transmission paths in side impacts lead to significant intrusion into the vehicle interior. Specifically, in traditional side impacts, the B-pillar relies solely on its own strength to resist deformation, lacking a direct load unloading path towards the chassis and frame. This results in the impact force being concentrated entirely on the B-pillar and sill beam, easily causing excessive inward bending of the B-pillar and severely compressing the passenger compartment (i.e., excessive intrusion into the vehicle interior).

[0024] 2. The need to meet the strength requirements of the vehicle's side panels has resulted in excessive weight. Specifically, to reduce the deformation of the B-pillar during a collision, thicker high-strength steel or welded solid reinforcing plates are typically added to the B-pillar to increase its rigidity. This leads to increased material costs and significantly exceeds the weight limit of the vehicle's side panel assembly, which is detrimental to reducing overall vehicle energy consumption and improving driving range.

[0025] In view of this, this application provides a vehicle side panel that can transfer the collision energy received by the B-pillar to the door sill beam, chassis longitudinal beam or battery pack shell, etc., to increase the load discharge path for the B-pillar, reduce the amount of deformation generated when the B-pillar is impacted, and thus effectively ensure the space inside the passenger compartment.

[0026] In this application, Figure 1 This is a view of the vehicle side panel from the outside to the inside in one embodiment of this application; Figure 2 This is a view of the vehicle side panel from the inside out in one embodiment of this application; Figure 3 This is a perspective view of the vehicle side panel from the inside out in one embodiment of this application; Figure 4 for Figure 3 A magnified view of a portion of region E in the middle; Figure 5 This is a view of the vehicle side panel from the outside to the inside after removing the exterior trim panel in one embodiment of this application; Figure 6 This is a view of the vehicle side panel from the inside out in one embodiment of this application after the exterior trim panel has been removed.

[0027] Firstly, this application provides a vehicle side panel, for reference Figure 1 and Figure 2 The vehicle body side panel includes B-pillar 1 and C-pillar 2, upper C-pillar beam 4, sill beam 3, at least one reinforcing tube beam 5 and multiple connecting tube beams 6.

[0028] The upper C-pillar beam 4 connects the upper ends of B-pillar 1 and C-pillar 2; the sill beam 3 connects the lower ends of B-pillar 1 and C-pillar 2. It should be understood that the sill beam 3 can be directly or indirectly connected to the lower end of C-pillar 2. Along the vertical Z direction of the vehicle, a reinforcing tube beam 5 is located between the lower C-pillar beam and the sill beam 3. The reinforcing tube beam 5 extends along the longitudinal X direction of the vehicle and connects B-pillar 1 and C-pillar 2. The upper C-pillar beam 4 and the reinforcing tube beam 5 form the window mounting area. Along the longitudinal X direction of the vehicle, multiple connecting tube beams 6 are spaced apart. Along the vertical Z direction of the vehicle, one end of each connecting tube beam 6 is connected to the reinforcing tube beam 5, and the other end is connected to the sill beam 3.

[0029] A C-pillar upper beam 4 is installed between the upper ends of B-pillar 1 and C-pillar 2, which can transmit the impact force received by B-pillar 1 from its upper end to the rear along the C-pillar upper beam 4. Along the vertical direction Z of the vehicle, one, two, or more reinforcing tube beams 5 are provided in the middle of B-pillar 1. Along the longitudinal direction X of the vehicle, the reinforcing tube beams 5 connect B-pillar 1 and C-pillar 2. When B-pillar 1 is impacted, the impact force borne by B-pillar 1 can be transmitted rearward along the reinforcing tube beams 5. Specifically, the connection between B-pillar 1 and the C-pillar upper beam 4 can be achieved by welding an upper reinforcing plate to B-pillar, and the connection between B-pillar 1 and the reinforcing tube beam 5 can be achieved by welding a middle reinforcing plate to B-pillar. Similarly, the connection between C-pillar 2 and the C-pillar upper beam 4 and the reinforcing tube beam 5 is also achieved by welding a reinforcing plate.

[0030] Multiple connecting tube beams 6 connect the reinforcing tube beam 5 and the sill beam 3, which can improve the overall rigidity of the reinforcing tube beam 5 and increase the force transmission path along the vertical Z direction of the vehicle. When the B-pillar 1 is hit, the impact force is transmitted along the B-pillar 1 to the reinforcing tube beam 5, and then through the connecting tube beams 6 to the sill beam 3, thus realizing the release of the impact force on the B-pillar 1.

[0031] It should be understood that in this application, a window mounting area is constructed between the upper C-pillar beam 4 and the reinforcing tube beam 5. Exemplarily, there are two or more reinforcing tube beams 5. The window mounting area is constructed between the upper C-pillar beam 4 and the uppermost (closest to the upper C-pillar beam 4) reinforcing tube beam 5. The connecting tube beam 6 connects only to the lowermost (closest to the sill beam 3) reinforcing tube beam 5, or the connecting tube beam 6 connects to each reinforcing tube beam 5 before connecting to the sill beam 3. The vehicle side panel in this application can be the left side panel. The left side panel does not have a door between the B-pillar 1 and C-pillar 2; that is, the vehicle side panel in this application only has a door at the driver's seat.

[0032] In this application, the B-pillar 1 and C-pillar 2 are connected by the upper side beam 4 of the C-pillar and at least one reinforcing tube beam 5, realizing multiple transmission paths for transmitting the collision force received by the B-pillar 1 to the rear. Then, the reinforcing tube beam 5 and the sill beam 3 are connected by the connecting tube beam 6 to transmit the collision force downward, thereby realizing the diversion of the collision force received by the B-pillar 1, reducing the deformation of the B-pillar 1, and thus reducing the occupancy of the B-pillar 1 in the passenger compartment space.

[0033] Optionally, the plurality of connecting tube beams 6 include a first connecting tube beam 61 adjacent to the B-pillar 1; the vehicle side panel also includes at least one first connector 7, which is connected between the B-pillar 1 and the first connecting tube beam 61. The first connector 7 can be one, two, or more. The first connector 7, connected between the B-pillar 1 and the first connecting tube beam 61, can not only improve the strength and rigidity of the first connecting tube beam 61, but also directly transfer the impact force on the B-pillar 1 to the first connecting tube beam 61, thereby further increasing the diversion of the impact force on the B-pillar 1 and reducing the deformation of the B-pillar 1.

[0034] Optionally, refer to Figure 3 At least one second connector 8 is provided between two adjacent connecting pipe beams 6. There may be one, two, or more second connectors 8. For example, two second connectors 8 are spaced apart along the vertical direction Z of the vehicle. The connection of the second connectors 8 between two adjacent connecting pipe beams 6 can improve the overall strength and rigidity of the multiple connecting pipe beams 6 and reduce the overall deformation of the connecting pipe beams 6.

[0035] In one specific embodiment, there are multiple first connectors 7 and second connectors 8. Along the front-rear direction X of the vehicle, each first connector 7 and its corresponding second connector 8 are arranged opposite to each other, so that the extension directions of the first connector 7 and the corresponding second connector 8 overlap, thereby further improving the strength and rigidity of the connecting tube beam 6 and forming a force transmission path along the front-rear direction of the vehicle.

[0036] Optionally, refer to Figure 3 The first connector 7 and the second connector 8 are both constructed in multiples, and each first connector 7 and the corresponding second connector 8 are constructed as an integral part along the front-rear direction X of the vehicle.

[0037] The first connector 7 and the corresponding second connector 8 are constructed as an integral part, which can further improve the connection strength between multiple connecting tube beams 6, and at the same time form a force transmission path along the front and rear direction of the vehicle, providing a reliable path for the release of the collision force on the B-pillar 1, and improving the anti-collision performance of the vehicle side.

[0038] Optionally, both the reinforcing tube beam 5 and the connecting tube beam 6 are constructed as hollow tubes. The use of hollow tubes in both the reinforcing tube beam 5 and the connecting tube beam 6 enhances torsional stiffness by utilizing the geometric and mechanical properties of hollow tubes. This significantly reduces the amount of metal used while maintaining the same or even higher stiffness, thereby reducing the weight of the vehicle's side panels, achieving lightweighting of the vehicle's side panels, and saving costs.

[0039] Optionally, refer to Figure 3 The side panel of the vehicle body also includes a first reinforcing plate 9, which is connected to the upper side beam 4 of the C-pillar and the side of the reinforcing tube beam 5 near the C-pillar 2.

[0040] The first reinforcing plate 9 extends along the vertical direction Z of the vehicle, which can improve the connection strength between the upper side beam 4 of the C-pillar and the reinforcing tube beam 5, thereby improving the strength and rigidity of the vehicle side panel and enhancing the anti-collision performance of the vehicle side panel.

[0041] Optionally, refer to Figure 4 The B-pillar 1 includes a main body 11 and a B-pillar reinforcing tube 12. The B-pillar reinforcing tube 12 is located on the main body 11. Both the main body 11 and the B-pillar reinforcing tube 12 are connected to the reinforcing tube beam 5. Both the main body 11 and the B-pillar reinforcing tube 12 are connected to the upper side beam 4 of the C-pillar. The B-pillar reinforcing tube 12 is constructed as an arc-shaped part that protrudes away from the interior of the vehicle body.

[0042] The upper end of the main body 11 is connected to the A-pillar via an upper reinforcing plate, and the lower end of the main body 11 is connected to the sill beam 3. The B-pillar reinforcing tube 12 is located inside the main body 11. The B-pillar reinforcing tube 12 extends along the vertical direction Z of the vehicle and is constructed as an outwardly protruding arc structure, so that the B-pillar 1 has a high section bending resistance coefficient, thereby resisting the bending moment generated by the collision in a side impact.

[0043] Optionally, refer to Figure 4 Along the vertical direction Z of the vehicle, the main body 11 includes a connected intermediate region 111 and a lower reinforcing region 112. Along the horizontal direction Y of the vehicle, the size of the intermediate region 111 is smaller than the size of the lower reinforcing region 112.

[0044] Specifically, along the front-rear direction X of the vehicle, the front side of the main body 11 is adapted to connect with the A-pillar side panel and door frame structure 40, and the B-pillar reinforcing tube 12 is located at the rear side of the main body 11. The part of the main body 11 located between the A-pillar side panel and door frame structure 40 and the B-pillar reinforcing tube 12 includes a connecting middle area 111 and a lower reinforcing area 112. Along the left-right direction Y of the vehicle, the lower reinforcing area 112 protrudes into the body in a larger dimension than the middle area 111, so that the closed cavity formed by the lower reinforcing area 112 and the trim panel and other structures is larger than the closed cavity formed by the middle area 111 and the trim panel and other structures. When the body is subjected to a side impact, the lower reinforcing area 112 increases the crumple space of the B-pillar 1, thereby reducing the amount of deformation of the B-pillar 1 into the body and reducing excessive bending or even breakage of the B-pillar 1.

[0045] In one specific embodiment, the body part 11 further includes an upper reinforcing region 113 along the vertical direction Z of the vehicle, and a middle region 111 connecting the upper reinforcing region 113 and the lower reinforcing region 112 along the horizontal direction Y of the vehicle. The size of the middle region 111 is smaller than that of the upper reinforcing region 113. The upper reinforcing region 113 adopts a larger cross-sectional size, which can improve the connection strength with the upper side beam 4 of the C-pillar and reduce the excessive bending or breakage of the B-pillar 1 at the upper welding area when subjected to a side impact.

[0046] Optionally, refer to Figure 5 and Figure 6The C-pillar 2 includes a first beam 21, a second beam 22, and a connecting beam 23. Along the vertical direction Z of the vehicle, the first beam 21 and the second beam 22 are spaced apart, and the connecting beam 23 connects the first beam 21 and the second beam 22. The first beam 21 is connected to the upper beam 4 of the C-pillar, and the second beam 22 is connected to the reinforcing tube beam 5. The side panel of the vehicle body also includes a first reinforcing beam 10, which is located between the first beam 21 and the second beam 22 and is angled to the vertical direction Z of the vehicle.

[0047] The first beam 21 is located above the second beam 22. The first beam 21 is connected to the upper beam 4 of the C-pillar, thereby transferring the impact force transmitted from the B-pillar 1 along the upper beam 4 of the C-pillar to the C-pillar 2, and then rearward. The second beam 22 is connected to the reinforcing tube beam 5, thereby transferring the impact force transmitted from the B-pillar 1 along the reinforcing tube beam 5 to the C-pillar 2, and then rearward. The connecting beam 23 connects the first beam 21 and the second beam 22, thereby increasing the strength of the first beam 21 and the second beam 22. The first reinforcing beam 10 connects the first beam 21 and the second beam 22, and along the vehicle's longitudinal direction X, the end of the first reinforcing beam 10 connected to the first beam 21 is located in front of the end of the first reinforcing beam 10 connected to the second beam 22, so that the first reinforcing plate 9, the second beam 22 and the first reinforcing beam 10 form a triangle, and the first beam 21, the connecting beam 23 and the first reinforcing beam 10 form a triangle, thereby improving the compressive strength of the upper side of the vehicle body and reducing the deformation of the upper side of the vehicle body.

[0048] Optionally, refer to Figure 6 The vehicle body side panel also includes a second reinforcing plate 20. Along the left-right direction Y of the vehicle, the second reinforcing plate 20 is located on one side of the connecting beam 23 and is connected to the first beam 21 and the second beam 22.

[0049] The second reinforcing plate 20 is disposed on the inner side of the connecting beam 23 and connects between the first beam 21 and the second beam 22, thereby improving the strength and rigidity of the entire C-pillar 2. The second reinforcing plate 20 is also provided with a stamped boss and other structures to improve the strength of the second reinforcing plate 20 and further transmit the force on the C-pillar 2 to the rear D-pillar 50 and the rear wheel arch body 301.

[0050] Secondly, this application provides a vehicle including the body side panel described in any of the above embodiments. The vehicle of this application has the beneficial effects of the body side panel described in any of the above embodiments. In one specific embodiment, the body side panel of this application is located on the left side of the vehicle body.

[0051] refer to Figure 5 and Figure 6 The vehicle body side panel in this application also includes the A-pillar side panel and door frame structure 40, the D-pillar 50 and the rear wheel arch composite reinforcement area 30.

[0052] In the front A-pillar side panel and doorway frame structure 40, the A-pillar reinforcing plate 401 and the inner A-pillar reinforcing plate 402 are welded to form the A-pillar foundation box section, constituting the main frame of the front doorway. An upper A-pillar reinforcing plate 403 is added above the A-pillar reinforcing plate 401 to enhance the rigidity of the connection between the top of the A-pillar and the upper beams 1 and 4 of the C-pillars; an A-pillar reinforcing supplement plate 404 is added to the inner side below the A-pillar reinforcing plate 401 to improve the bending resistance of the lower end of the A-pillar reinforcing plate 401 in the event of a frontal or side impact. The A-pillar reinforcing plate 401 is connected to the middle section 60 of the outer sill reinforcing beam below it, and the rear section 70 of the outer sill reinforcing beam is connected to the B-pillar 1. The middle section 60 and the rear section 70 of the outer sill reinforcing beam are located on the outer side of the sill beam 3. The reinforced door ring, composed of an A-pillar reinforcement plate 401, an upper A-pillar reinforcement plate 403, a middle section 60 of the outer sill reinforcement beam, and a rear section 70 of the outer sill reinforcement beam, is made of ultra-high strength hot-formed steel. It is a composite structure formed by stamping, edge flanging, overlapping, and multi-point welding. After assembly, this structure forms a wide box-shaped closed section in the lower part of the A-pillar reinforcement plate 401, providing extremely high bending and torsional stiffness to the front of the door opening. The upper and lower hinge mounting areas of the A-pillar reinforcement plate 401 are independently welded with upper A-pillar hinge reinforcement plates 405 and lower A-pillar hinge reinforcement plates 406. This localized reinforcement design eliminates the need for overall weight-adding reinforcement of the A-pillar in existing technologies, further achieving lightweighting of the vehicle's side panels. In other words, in this application, the main reinforcing plate of the A-pillar side panel and door frame structure 40 is not thickened as a whole. In this application, the upper hinge reinforcing plate 405 and the lower hinge reinforcing plate 406 of the A-pillar are independently welded only at the upper hinge position and the lower hinge position, which are subjected to frequent impacts of opening and closing of the car door, respectively, so as to achieve precise reinforcement of the force.

[0053] The D-pillar 50 is composed of three sections from top to bottom: the upper section 501 of the inner D-pillar panel, the middle section 502 of the inner D-pillar panel, and the lower section 503 of the inner D-pillar panel. An upper section 504 of the inner D-pillar reinforcing plate is located on the outer side of the upper section 501, and a lower section 505 of the inner D-pillar reinforcing plate is located on the outer side of the lower section 503. A left connecting plate 506 connects the lower section 503 of the inner D-pillar panel to the rear wheel arch body 301. The multi-segment splicing method of the D-pillar 50 allows for varying degrees of local structural reinforcement at different connection points using high-strength materials as needed.

[0054] In the rear wheel arch composite reinforcement zone 30, a rear wheel arch reinforcement plate 302 and an upper rear wheel arch reinforcement plate 303 are welded to the inner and outer sides of the rear wheel arch body 301, respectively, to improve local modal stiffness. The rear wheel arch reinforcement plate 302 is connected to the lower section 505 of the D-pillar reinforcement plate, and the upper rear wheel arch reinforcement plate 303 is connected to the second beam 22 or the reinforcing tube beam 5 of the C-pillar 2, forming a multi-cavity, high-strength closed-loop rear frame, which significantly improves the vehicle's torsional stiffness on bumpy roads and at high speeds, and reduces road noise in the rear compartment. The rear wheel arch reinforcement plate 302 and the upper rear wheel arch reinforcement plate 303 are stamped with multiple reinforcing ribs to disperse local stress.

[0055] The rear wheel arch body 301 is also provided with an irregularly shaped hollow opening 3011 to reduce redundant material in non-load-bearing areas, reduce unsprung weight at the rear of the vehicle, and thus reduce the overall weight of the vehicle. At the same time, the hollow opening can also serve as a charging port or refueling port and a cable routing function.

[0056] Above the rear wheel arch body 301, there is also a rear crossbeam connecting plate 304 connected to the second beam 22 of the C-pillar 2, a rear section 80 of the lower outer panel of the window frame, and a rear window frame outer panel 90 connected to the first beam 21 of the C-pillar 2, which together transmit the force of the wheel arch to the rear roof frame of the vehicle body in a closed loop.

[0057] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
