Description

Technical Field

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

[0002] With the development of automotive lightweighting technology, aluminum alloy materials are being used more and more widely in vehicle body structures. Among them, the sill beam, as a key component connecting the side panel assembly, directly affects the torsional stiffness and collision safety of the entire vehicle.

[0003] However, the structural stability of the side panel assembly in the aforementioned technologies is relatively poor, which affects the impact resistance and torsional resistance of the side panel assembly. Utility Model Content

[0004] In view of this, embodiments of this application provide a side panel assembly and a vehicle to solve the technical problem in the above-mentioned related technologies that the structural stability of the side panel assembly is relatively poor, affecting the impact resistance and torsional resistance of the side panel assembly.

[0005] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0006] A first aspect of this application provides a side panel assembly, comprising:

[0007] The threshold beam includes a first side and a second side disposed opposite to each other along a first direction, and a first top surface connected to the first side, wherein the first top surface intersects with the first side.

[0008] A side frame is located on the side of the sill beam facing the first side, a portion of the side frame is connected to the first side, and a portion of the side frame is connected to the first top surface;

[0009] A side panel is provided on the side of the sill beam facing away from the side frame. A portion of the side panel is connected to the second side surface, and a portion of the side panel is connected to the side frame.

The sill beam, with its intersecting first side and first top surface, forms an L-shaped connection interface, providing two intersecting installation references for the side panel frame. The side panel frame is positioned on the first side of the sill beam, enabling it to simultaneously form a lateral connection with the first side and a vertical connection with the first top surface. This double-sided connection overcomes the limitations of traditional single-sided connections. The inner side panel forms a symmetrical support structure on the other side of the sill beam, directly connecting to the second side and bridging with the side panel frame, creating a closed-loop force transmission path. The outer side panel indirectly connects to the sill beam through the side panel frame, avoiding direct obstruction of the connection space between the frame and the top surface of the sill beam, ensuring effective connection points between the frame and the sill beam in both the Z and X directions. Through spatially staggered arrangement and optimized connection sequence, the components form a three-dimensional, intersecting force transmission network, improving overall stiffness and torsional resistance while maintaining a lightweight structure.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0055] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0056] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0057] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0058] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0059] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0060] The side panel assembly in the aforementioned technologies exhibits relatively poor structural stability, affecting its impact and torsional resistance. This problem arises because, in traditional vehicle body structures, the side panel frame is typically connected to the outer side panel first. This connection method causes the outer side panel to obstruct the mounting position of the side panel frame and the top surface of the sill beam, resulting in a lack of effective connection points between the side panel frame and the sill beam. This structural defect not only reduces the connection stability between the sill beam and the side panel frame but also generates abnormal noises during vehicle operation, affecting passenger comfort. Furthermore, in side collision conditions, this connection structure is prone to weld failure, increasing vehicle body intrusion and endangering passenger safety. While existing technologies attempt to improve connection strength by increasing the number of weld points, the obstruction effect of the outer side panel makes it difficult to achieve effective connections between the side panel frame and the sill beam in multiple directions, failing to fundamentally solve the problem of insufficient connection strength. Therefore, existing technologies urgently need improvement to address these issues.

[0061] To address the aforementioned issues, this application provides a side panel assembly and vehicle. By reconstructing the connection sequence and spatial layout of the side panel assembly, multi-dimensional connection reinforcement is achieved. The sill beam, with its intersecting first side and first top surface, forms an L-shaped connection interface, providing two intersecting installation references for the side panel frame. The side panel frame is positioned on the first side of the sill beam, enabling it to simultaneously form a lateral connection with the first side and a vertical connection with the first top surface. This double-sided connection method overcomes the limitations of traditional single-sided connections. The inner side panel forms a symmetrical support structure on the other side of the sill beam, directly connecting to the second side and bridging with the side panel frame, constructing a closed-loop force transmission path. The outer side panel indirectly connects to the sill beam through the side panel frame, avoiding direct obstruction of the connection space between the frame and the top surface of the sill beam, ensuring effective connection points between the frame and the sill beam in both the Z and X directions. Through spatially staggered arrangement and optimized connection sequence, the components form a three-dimensional, intersecting force transmission network, improving overall stiffness and torsional resistance while maintaining a lightweight structure.

[0062] The side panel assembly and vehicle provided in this application will now be described with reference to the accompanying drawings and specific embodiments.

[0063] Reference Figure 1 , Figure 2 and Figure 3 This application provides a side panel assembly, which may include a sill beam 100, a side panel frame 200, an inner side panel 300, and an outer side panel 400.

[0064] The sill beam 100 may include a first direction (e.g.) Figure 3 A first side surface 110 and a second side surface 120 are arranged opposite each other in the Y direction, and a first top surface 130 is connected to the first side surface 110. The first top surface 130 intersects with the first side surface 110.

[0065] The first direction can be the width direction of the vehicle body. The first side surface 110 refers to the vertical surface of the sill beam 100 facing the outer side of the vehicle, which can be implemented using an aluminum alloy profile. The first top surface 130 refers to the plane that forms a right angle connection with the first side surface 110, and this plane is perpendicular to the height direction of the vehicle body (e.g., ...). Figure 3 (in the Z direction).

[0066] The side frame 200 is located on the side of the sill beam 100 facing the first side surface 110. A portion of the side frame 200 is connected to the first side surface 110, and a portion of the side frame 200 is connected to the first top surface 130. The connection between the side frame 200 and the first top surface 130 refers to establishing a vertical load transfer path through riveting or welding, which enables the distributed transmission of multi-directional loads.

[0067] The inner side panel 300 is located on the side of the sill beam 100 facing away from the side frame 200. A portion of the inner side panel 300 is connected to the second side panel 120, and a portion of the inner side panel 300 is connected to the side frame 200.

[0068] The outer side panel 400 is disposed on the side of the side frame 200 facing away from the sill beam 100 along the first direction, and the outer side panel 400 is connected to the first side panel 110 through the side frame 200.

[0069] The connection between the side outer panel 400 and the side frame 200 means that the side outer panel 400 and the side frame 200 form a composite connection structure, which can be achieved by laser welding combined with adhesive bonding.

[0070] Specifically, the sill beam 100 forms an "L"-shaped connection interface with the first side surface 110 and the first top surface 130, providing an orthogonal installation reference for the side frame 200. The side frame 200 connects laterally to the first side surface 110 and vertically to the first top surface 130, forming a bidirectional load transfer channel. The inner side panel 300 constructs a symmetrical support structure on the other side of the sill beam 100, forming a closed-loop force transmission path by bridging the side frame 200. The indirect connection between the outer side panel 400 and the side frame 200 preserves the direct contact area between the frame and the top surface of the sill, ensuring the effective establishment of vertical connection points. The components are spatially staggered to form a three-dimensional, intersecting force transmission network, achieving distributed load transmission under collision conditions.

[0071] This application provides a side panel assembly that achieves multi-dimensional connection reinforcement by reconstructing the connection sequence and spatial layout of the side panel assembly. The sill beam 100 forms an L-shaped connection interface by setting a first side surface 110 and a first top surface 130 with intersecting features, providing two intersecting installation references for the side panel frame 200. The side panel frame 200 is configured on the first side surface 110 side of the sill beam 100, enabling it to simultaneously form a lateral connection with the first side surface 110 and a vertical connection with the first top surface 130. This double-sided connection method overcomes the limitations of traditional single-sided connections. The inner side panel 300 forms a symmetrical support structure on the other side of the sill beam 100, directly connecting to the second side surface 120 and also bridging with the side panel frame 200, constructing a closed-loop force transmission path. The side panel 400 is indirectly connected to the sill beam 100 through the side frame 200, avoiding the outer panel directly obscuring the connection space between the frame and the top surface of the sill beam 100, and ensuring that the frame and the sill beam 100 can establish effective connection points in both the Z and X directions. Through spatial staggered arrangement and optimized connection sequence, the various components form a three-dimensional intersecting force transmission network, which improves the overall rigidity and torsional resistance while maintaining a lightweight structure.

[0072] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments, the side frame 200 may include an A-pillar outer panel 210, which may include a first outer side surface 211 and a first outer top surface 212.

[0073] The first outer surface 211 is disposed facing the first side surface 110 and connected to the first side surface 110. The first outer top surface 212 is connected to and intersects with the first outer surface 211. The first outer top surface 212 is disposed facing the first top surface 130 and is used to connect to the first top surface 130.

[0074] The first outer surface 211 refers to the plate-like structure in the A-pillar outer panel 210 that is in parallel contact with the first side surface 110 of the sill beam 100. Specifically, it can be formed using a stamping process, and its surface is connected to the first side surface 110 of the sill beam 100 through riveting or welding to transfer lateral loads. The first outer top surface 212 refers to the planar structure in the A-pillar outer panel 210 that is connected at a right angle to the first outer surface 211. The first outer top surface 212 can be connected to the first top surface 130 of the sill beam 100 through riveting or welding to provide longitudinal support.

[0075] By incorporating the A-pillar outer panel 210 as part of the side frame 200, its first outer surface 211 is directly connected to the first side surface 110 of the sill beam 100, thus fixing the A-pillar outer panel 210 to the sill beam 100 in the lateral direction. Simultaneously, the first outer top surface 212 is connected to the first top surface 130, establishing a supporting relationship in the vertical direction. This dual connection method overcomes the limitations of traditional structures relying solely on a single planar connection, creating a three-dimensional connection structure between the A-pillar outer panel 210 and the sill beam 100. The connection between the first outer surface 211 and the first side surface 110 bears the lateral load transfer, while the connection between the first outer top surface 212 and the first top surface 130 provides longitudinal support; both work together to enhance the structural rigidity at the joint. By designing the A-pillar outer panel 210 to simultaneously cover the side and top surfaces of the sill beam 100, forming a wrap-around connection interface, impact forces can be more effectively dispersed under collision conditions, avoiding connection failure caused by stress concentration.

[0076] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments, the side frame 200 may include the outer A-pillar panel 210 along a second direction (e.g., Figure 4 The outer B-pillar panels 220 are arranged and connected in the X direction, with the second direction perpendicular to the first direction. The outer B-pillar panels 220 may include a second outer side surface 221 and a second outer top surface 222.

[0077] The second outer side surface 221 and the first outer side surface 211 are arranged along the second direction. The second outer side surface 221 is connected to the first side surface 110. The second outer top surface 222 is connected to and intersects with the second outer side surface 221. The second outer top surface 222 is connected to the first top surface 130.

[0078] The second direction refers to the length direction of the sill beam 100. The second outer surface 221 refers to the surface of the B-pillar outer panel 220 facing the first side 110 of the sill beam 100. It can be a planar or curved structure and is fixed to the first side 110 by riveting or welding to form rigid support in the lateral direction. The second outer top surface 222 refers to the surface of the top of the B-pillar outer panel 220 that is perpendicularly connected to the second outer surface 221. It can be a structure that fits against the first top surface 130 and is connected by riveting or welding to provide shear resistance in the vertical direction.

[0079] By arranging the B-pillar outer panel 220 and the A-pillar outer panel 210 along a second direction perpendicular to the first direction, the B-pillar outer panel 220 can form a multi-dimensional connection structure with the sill beam 100. The second outer side surface 221 is arranged along the second direction with the first outer side surface 211 and is connected to the first side surface 110 of the sill beam 100, thus fixing the B-pillar outer panel 220 in the lateral direction; the second outer top surface 222 intersects with the second outer side surface 221 and is connected to the first top surface 130 of the sill beam 100, thus providing vertical support for the B-pillar outer panel 220. This bidirectional connection structure enables the B-pillar outer panel 220 and the sill beam 100 to form a three-dimensional connection, which can effectively disperse the impact force during side collisions and avoid connection failure caused by single-point stress concentration. At the same time, the arrangement and connection method of the B-pillar outer panel 220 and the A-pillar outer panel 210 enhances the continuity of the overall structure of the side frame 200 and further improves the deformation resistance of the side assembly.

[0080] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments, the side panel 400 may include a third side surface 410 and a third top surface 420.

[0081] The third side 410 is disposed facing the first outer side 211 and the second outer side 221, and the third side 410 is connected to the first side 110 through the first outer side 211 and the second outer side 221.

[0082] The third top surface 420 is disposed toward the first top surface 130, and there is a gap between the third top surface 420 and the first outer top surface 212, and / or, there is a gap between the third top surface 420 and the second outer top surface 222.

[0083] The third side 410 refers to the side of the outer side panel 400 facing the side frame 200. It can be made of stamped metal sheet and is indirectly connected to the first side 110 of the sill beam 100 via the first outer side 211 and second outer side 221 of the side frame 200, avoiding direct coverage of the connection area between the side frame 200 and the sill beam 100. The third top surface 420 refers to the portion of the outer side panel 400 facing the first top surface 130 of the sill beam 100. A gap is maintained between this portion and the first outer top surface 212 or the second outer top surface 222 of the side frame 200, forming a buffer cavity. The gap refers to the non-contact area between the third top surface 420 and the top surface of the side frame 200. This gap can be achieved by adjusting the installation position or structural dimensions of the outer side panel 400, providing deformation allowance for the connection structure.

[0084] By aligning the third side surface 410 of the side panel 400 with the first outer side surface 211 and the second outer side surface 221 of the side frame 200, and indirectly connecting it to the first side surface 110 of the sill beam 100 through these two outer sides, the side panel 400 avoids directly covering the connection area between the side frame 200 and the top surface of the sill beam 100. When the third top surface 420 is aligned with the first top surface 130 of the sill beam 100, a gap is maintained between it and the first outer top surface 212 or the second outer top surface 222, forming a buffer cavity structure. This cavity can absorb energy through deformation when subjected to impact, while the reserved gap provides deformation allowance for the connection structure between the first outer top surface 212 and / or the second outer top surface 222 and the first top surface 130, preventing connection failure caused by rigid collision. Through the dual indirect connection between the third side panel 410 and the side frame 200, and the non-contact layout between the third top surface 420 and the top surface of the side frame 200, the installation stability of the side outer panel 400 is ensured, and the impact resistance is improved.

[0085] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments, the third side 410 and the first outer side 211 are riveted to the first side 110, and the third side 410 and the second outer side 221 are riveted to the first side 110.

[0086] By riveting the third side surface 410 of the side panel 400 together with the first outer side surface 211 and the second outer side surface 221 of the side frame 200 to the first side surface 110 of the sill beam 100, an integrated connection of the three components is achieved. Specifically, the third side surface 410 and the first outer side surface 211 are riveted together to the first side surface 110, so that the side panel 400, while connecting itself, simultaneously fixes the A-pillar panel 210 to the sill beam 100; the third side surface 410 and the second outer side surface 221 are riveted together to the first side surface 110, thus simultaneously fixing the B-pillar panel 220 to the sill beam 100. This synchronous riveting method breaks through the limitations of traditional step-by-step welding, eliminating the obstruction of the frame connection position by the side panel 400, and completing the connection of the three components in a single operation, significantly improving assembly efficiency and connection reliability. The riveting process also enhances the shear resistance at the joint, effectively dispersing impact loads during side collisions and avoiding structural weaknesses caused by step-by-step connections.

[0087] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments, the first outer top surface 212 is riveted to the first top surface 130, and the second outer top surface 222 is riveted to the first top surface 130.

[0088] The first outer top surface 212 of the A-pillar outer plate 210 of the side frame 200 is directly connected to the first top surface 130 of the sill beam 100 by riveting, and the second outer top surface 222 of the B-pillar outer plate 220 is riveted to the first top surface 130 of the same sill beam 100, thus achieving double fixation of the side frame 200 and the sill beam 100 in the vertical direction.

[0089] The riveting process avoids the problem of missing connection points caused by the side panel 400 obstructing the connection points in traditional welding, allowing the A-pillar outer panel 210 and the B-pillar outer panel 220 to form a rigid connection with the sill beam 100 on their top planes. This double-top-plane riveting structure not only enhances the shear resistance between the side frame 200 and the sill beam 100, but also optimizes the load transfer path through the distribution of riveting points, effectively dispersing the impact force during side collisions.

[0090] Meanwhile, riveting is more suitable for connecting aluminum alloy materials than traditional welding, solving the problem of connecting dissimilar materials. It also allows for efficient assembly without complex tooling, avoiding the impact of welding deformation on the vehicle body precision. By simultaneously riveting the A-pillar outer panel 210 and the B-pillar outer panel 220 on the top surface of the sill beam 100, a continuous wrapping connection structure is formed, significantly improving the overall rigidity of the vehicle body joint.

[0091] Reference Figure 2 and Figure 3 In some embodiments, the threshold beam 100 may further include a second top surface 140 adjacent to the first top surface 130 along a first direction, and a portion of the side panel 300 is connected to the second top surface 140.

[0092] The second top surface 140 refers to the extended surface on the sill beam 100 adjacent to the first top surface 130 along the first direction. It can be formed using stamping or extrusion molding processes. Together with the first top surface 130, it constitutes the top support structure of the sill beam 100, expanding the connection area of ​​the inner side panel 300. The connection of a portion of the inner side panel 300 to the second top surface 140 means that the edge area of ​​the inner side panel 300 is fixed to the second top surface 140 by riveting, welding, or bonding, forming a continuous connection interface extending along the first direction, thereby increasing the contact area between the inner side panel 300 and the sill beam 100.

[0093] By adding a second top surface 140 adjacent to the first top surface 130 on the sill beam 100, the inner side panel 300 is connected not only to the second side surface 120 of the sill beam 100 but also to the second top surface 140. The second top surface 140, adjacent to the first top surface 130 in the first direction, expands the contact surface between the sill beam 100 and the inner side panel 300, allowing the inner side panel 300 to establish connections with the sill beam 100 in both the second side surface 120 and the second top surface 140. This multi-directional connection structure overcomes the limitations of traditional single-side connections, increasing the constraint force between the inner side panel 300 and the sill beam 100, thereby dispersing the direction of external impact or vibration loads. The connection between the inner side panel 300 and the second top surface 140 further strengthens the supporting effect of the sill beam 100 on the inner side panel 300, preventing deformation or loosening caused by concentrated force at a single connection point, thus improving the overall impact resistance and stability of the structure.

[0094] Reference Figure 2 and Figure 3 In some embodiments, the inner side panel 300 may include an inner A-pillar panel 310 corresponding to the outer A-pillar panel 210. The inner A-pillar panel 310 may include a first inner side surface 311 and a first inner top surface 312.

[0095] The first inner side surface 311 is disposed facing the second side surface 120 and is connected to the second side surface 120. The first inner top surface 312 is connected to the first inner side surface 311 and is disposed facing the second top surface 140 and is connected to the second top surface 140.

[0096] The A-pillar inner panel 310 refers to the internal support component that forms a spatial relationship with the outer panel of the A-pillar area of ​​the vehicle. It can be made of stamped aluminum alloy sheet, and its outline shape complements that of the A-pillar outer panel 210. The first inner surface 311 refers to the vertical plane in the A-pillar inner panel 310 that forms a surface contact with the second surface 120 of the sill beam 100. It can be achieved using a planar bending structure, increasing the contact area to enhance lateral connection strength. The first inner top surface 312 refers to the horizontal plane in the A-pillar inner panel 310 that forms a surface contact with the second top surface 140 of the sill beam 100. It can be achieved using a stepped flange structure, enhancing longitudinal support stability through orthogonal connections.

[0097] By setting an A-pillar inner panel 310 structure corresponding to the space of the A-pillar outer panel 210, a multi-dimensional connection is formed between the side inner panel 300 and the sill beam 100. Specifically, the first inner side surface 311 is set towards and directly connected to the second side surface 120 of the sill beam 100. This design strengthens the lateral connection strength by increasing the contact area between the side inner panel 300 and the side of the sill beam 100. The first inner top surface 312 is connected to the second top surface 140 of the sill beam 100. This feature forms a supplementary connection in the longitudinal dimension, allowing the A-pillar inner panel 310 to simultaneously cover both the side and top surfaces of the sill beam 100, two orthogonal planes. This double-sided connection structure changes the limitations of traditional single-point welding. By dispersing the impact force through the orthogonal mechanical transmission path, in the event of a side collision, the double connection between the second side surface 120 and the second top surface 140 can form a composite support structure, effectively suppressing the relative displacement between the side inner panel 300 and the sill beam 100, thereby improving the overall structure's resistance to deformation. In particular, the connection direction between the first inner top surface 312 and the second top surface 140 is perpendicular to the connection direction between the first inner side surface 311 and the second side surface 120. This orthogonal joint method can resist impact loads from different directions at the same time, solving the problem that traditional single-plane connections are prone to failure under complex stress conditions.

[0098] Reference Figure 2 and Figure 4 In some embodiments, the inner side panel 300 may include an inner B-pillar panel 320 corresponding to the outer B-pillar panel 220. The inner B-pillar panel 320 may include a second inner side surface 321 and a second inner top surface 322.

[0099] The second inner side surface 321 is disposed facing the second side surface 120 and is connected to the second side surface 120. The second inner top surface 322 is connected to the second inner side surface 321 and is disposed facing the second top surface 140 and is connected to the second top surface 140.

[0100] The second inner surface 321 refers to the vertical surface of the B-pillar inner panel 320 that is in parallel contact with the second side surface 120 of the sill beam 100. Specifically, it can be formed into a planar structure using a stamping process and fixedly connected to the second side surface 120 by riveting or welding. This surface is used to transfer loads in the lateral direction. The second inner top surface 322 refers to the horizontal surface of the B-pillar inner panel 320 that is in parallel contact with the second top surface 140 of the sill beam 100. Specifically, it can be formed into a bent structure using a bending process and fixedly connected to the second top surface 140 by riveting or welding. This surface is used to provide support in the vertical direction.

[0101] By setting an inner B-pillar panel 320 corresponding to the outer B-pillar panel 220, the second inner side surface 321 of the inner B-pillar panel 320 is directly connected to the second side surface 120 of the sill beam 100, and the second inner top surface 322 is connected to the second top surface 140 of the sill beam 100, forming two connection surfaces in different directions. The connection between the second inner side surface 321 and the second side surface 120 enhances the lateral structural stability of the side panel 300 and the sill beam 100, while the connection between the second inner top surface 322 and the second top surface 140 provides vertical support, making the inner B-pillar panel 320 and the sill beam 100 form a wrap-around connection structure. This double-sided connection method not only disperses the impact force during a collision, but also improves the overall shear resistance and deformation resistance by increasing the contact area and the number of connection points, thereby effectively reducing the amount of vehicle body intrusion during a side collision and ensuring the safety of the passenger compartment.

[0102] This application also provides a vehicle that may include a body and the aforementioned side panel assembly.

[0103] By using the aforementioned side panel assembly, the vehicle of this application can simplify vehicle assembly efficiency, improve the impact resistance and torsional resistance of the vehicle side, and enhance vehicle safety.

[0104] In some embodiments, the vehicle may be a gasoline-powered vehicle, or it may be a new energy vehicle, such as a pure electric vehicle (PEV / BEV), a range-extended electric vehicle (REEV), a hybrid electric vehicle (HEV), or a fuel cell electric vehicle. The vehicle may also be any vehicle equipped with a battery.
