Description

Technical Field

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

[0002] The C-pillar assembly is an important component of the vehicle's side panel, consisting of the upper beam and the inner side panel, which are connected together by welding, riveting, and other methods.

[0003] In the prior art, in order to reduce the weight of the vehicle body, the upper beam and the inner side panel are relatively thin, and a cavity is formed between the upper beam and the inner side panel.

[0004] However, for larger vehicles, the cavity volume is larger, and the upper beam and the inner wall of the side panel are thinner, resulting in lower structural strength of the C-pillar assembly, which affects the overall safety of the vehicle. Utility Model Content

[0005] In view of this, this application provides a vehicle body pillar assembly and a vehicle, which helps to enhance the structural strength of the vehicle body pillar assembly and improve vehicle safety.

[0006] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0007] On one hand, this application provides a vehicle body pillar assembly, including: an upper side beam; a side inner panel, the side inner panel being opposite to and connected to the upper side beam in the left-right direction of the vehicle, the side inner panel and the upper side beam jointly defining a mounting cavity; and a reinforcing member, the reinforcing member being disposed in the mounting cavity and being connected to the upper side beam and the side inner panel respectively.

[0008] The vehicle body pillar assembly of this application incorporates a reinforcing member within the mounting cavity. This reinforcing member supports the upper side beam and the inner side panel, forming a more robust frame structure that enhances the structural strength of the vehicle body pillar assembly. In the event of a collision, the reinforcing member can disperse and absorb some of the energy generated, reducing the likelihood of localized deformation or damage to the vehicle body pillar assembly. This provides sufficient survival space for occupants, improving the vehicle's collision resistance and ultimately enhancing its safety and reliability. Furthermore, the reinforcing member divides the mounting cavity into two smaller chambers, mitigating stress concentration and resulting in a more uniform stress distribution, which in turn improves the durability and service life of the vehicle body pillar assembly.

[0009] In one possible implementation, the reinforcing member includes: a support body whose shape is adapted to the cross-sectional shape of the mounting cavity; a first connecting flange disposed on a portion of the support body facing the inner side panel, the first connecting flange being connected to the inner side panel; and a second connecting flange disposed on a portion of the support body facing the upper beam, the second connecting flange being connected to the upper beam.

[0010] This design helps ensure the stability of the reinforcing components, thereby enhancing the overall structural strength of the body pillar assembly. Furthermore, this connection method allows for more even load distribution among the various components of the body pillar assembly, helping to avoid stress concentration and improving the load-bearing capacity and deformation resistance of the body pillar assembly. Simultaneously, fixing the components via the first and second connecting flanges optimizes the structural layout of the body pillar assembly, allowing the reinforcing components to better integrate into the overall body structure, ensuring structural strength without adversely affecting other vehicle functions and performance.

[0011] In one possible implementation, there are multiple first connecting flanges, which are distributed at circumferential intervals along the support body.

[0012] Thus, the multiple first connecting flanges effectively distribute the load, preventing deformation or damage to the inner side panel caused by excessive stress at local connection points, thereby improving the stability and reliability of the vehicle pillar assembly. Simultaneously, the spaced distribution of the multiple first connecting flanges enhances the contact area and connection strength between the reinforcing member and the inner side panel, further improving the overall structural strength and deformation resistance of the vehicle pillar assembly, providing strong protection for the vehicle's safety and durability.

[0013] In one possible implementation, the support body is further provided with a connecting structure, which connects two adjacent first connecting flanges and protrudes toward the second connecting flange.

[0014] Thus, the connecting structure between the first connecting flanges provides additional support and stability for the reinforcement, enhancing its structural integrity and improving the connection strength between the reinforcement and the inner side panel. The protrusion of the connecting structure towards the second connecting flange provides clearance for the inner side panel, preventing interference and reducing noise generated by collisions between the connecting structure and the inner side panel when the vehicle pillar assembly is subjected to vibration or bumps. This further improves the driving and riding experience.

[0015] In one possible implementation, the first connecting flange is provided with a first connecting hole, and the inner side panel is provided with a second connecting hole. The first connecting flange and the inner side panel are connected by fasteners passing through the first connecting hole and the second connecting hole.

[0016] In this way, by fastening the inner side panel to the first connecting flange together, the connection strength between the inner side panel and the first connecting flange can be guaranteed, and loosening or deformation at the connection point can be avoided. The operation is convenient and helps to improve the assembly efficiency of the body pillar assembly.

[0017] In one possible implementation, there are multiple second connecting flanges, which are distributed at circumferential intervals along the support body.

[0018] In this way, multiple second connecting flanges can prevent local stress concentration and deformation of the upper beam. At the same time, the spaced distribution of multiple second connecting flanges helps to increase the contact area between the reinforcement and the upper beam, improve the connection strength between the second connecting flanges and the upper beam, and thus improve the structural strength of the body pillar assembly and the vehicle's collision resistance.

[0019] In one possible implementation, the first connecting flange and the second connecting flange extend toward both sides of the support body along the thickness direction.

[0020] Thus, the first and second connecting flanges extend in opposite directions, allowing the reinforcement to provide stable support and connection from multiple directions. This enhances the structural strength of the body pillar assembly and optimizes the force transmission path. When the body pillar assembly is impacted, the impact force is more evenly distributed between the upper beam, the reinforcement, and the inner side panel, preventing excessive local pressure from causing force transmission path failure. This helps ensure the integrity of the passenger compartment inside the vehicle, thereby improving the vehicle's safety and reliability.

[0021] In one possible implementation, the second connecting flange is welded to the upper beam.

[0022] This ensures the structural strength of key components of the vehicle body pillar assembly and prevents the assembly from maintaining its structural integrity under extreme conditions such as collisions, thus avoiding structural disintegration that could endanger the safety of occupants and further improving vehicle safety and reliability.

[0023] In one possible implementation, the mounting cavity includes chambers located on both sides of the reinforcing member, and the support body is provided with electrophoresis holes extending along its own thickness direction, the electrophoresis holes being used to connect the chambers on both sides of the mounting cavity; and / or, the support body is provided with positioning holes, the positioning holes being used to position the reinforcing member.

[0024] Thus, during electrophoresis treatment, the electrophoretic solution inside the mounting cavity can flow through the electrophoresis holes into both chambers, ensuring the uniformity of the electrophoretic coating. Furthermore, a single injection of electrophoretic solution completes the electrophoretic treatment of the inner walls of both chambers, improving the assembly efficiency of the body pillar assembly. Additionally, when installing reinforcement components, their position can be defined first using positioning holes, and then fastened to the inner wall of the side panel and the upper beam using fasteners or welding. This improves the accuracy of reinforcement component assembly, reduces assembly errors, and increases assembly efficiency.

[0025] On the other hand, this application also provides a vehicle, including: the body pillar assembly described in any of the above claims.

[0026] By using the aforementioned body pillar assembly, the vehicle of this application can improve the overall collision resistance of the vehicle without affecting the vehicle weight, enhance the overall bending and torsional stiffness of the body, as well as the bending mode, torsional mode, and local modes of the side inner panels, thereby enhancing the safety and reliability of the vehicle.

[0039] 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.

[0040] 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.

[0041] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the orientation of the components shown 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 orientation of the components in the accompanying drawings.

[0042] 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.

[0043] 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.

[0044] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0045] In existing technology, the C-pillar assembly includes an upper side beam and a side inner panel, which are connected together by welding, riveting, or other methods. To reduce vehicle weight, the upper side beam and the side inner panel are relatively thin, forming a cavity between them. However, for larger vehicles, the cavity volume is large, and the thin walls of the upper side beam and the side inner panel result in lower structural strength of the C-pillar assembly, affecting the overall safety of the vehicle.

[0046] To address the aforementioned technical problems, this application provides a vehicle body pillar assembly and a vehicle. The vehicle body pillar assembly includes an upper side beam, a side outer panel, and a reinforcing member. The upper side beam and the side outer panel together define a mounting cavity. The reinforcing member supports the upper side beam and the side inner panel. A more robust frame structure is formed between the reinforcing member, the upper side beam, and the side inner panel, which is beneficial to the structural strength of the vehicle body pillar assembly. When a vehicle collision occurs, the reinforcing member can disperse and absorb some of the energy generated by the collision, reducing the possibility of local deformation or damage to the vehicle body pillar assembly, thereby providing sufficient survival space for occupants and improving the vehicle's collision resistance, thus enhancing the vehicle's safety and reliability. Simultaneously, the reinforcing member divides the mounting cavity into two smaller chambers, which helps alleviate stress concentration and makes the stress distribution more uniform, thus improving the durability and service life of the vehicle body pillar assembly.

[0047] It should be noted that the vehicle body pillar assembly provided in this application embodiment can be applied to various different vehicles.

[0048] refer to Figure 1 and Figure 2 On the one hand, this application provides a vehicle body pillar assembly 100, which can be any one of an A-pillar assembly, a B-pillar assembly, or a C-pillar assembly, and is particularly applicable to a C-pillar assembly. The following description uses the C-pillar assembly as an example for the vehicle body pillar assembly 100.

[0049] The vehicle body pillar assembly 100 of this application embodiment includes: an upper side beam 110, a side inner panel 120, and a reinforcing member 130. The side inner panel 120 and the upper side beam 110 are opposite to and connected in the left-right direction of the vehicle, and the side inner panel 120 and the upper side beam 110 together define a mounting cavity. The reinforcing member 130 is disposed in the mounting cavity and is connected to the upper side beam 110 and the side inner panel 120 respectively.

[0050] In this embodiment, the reinforcing member 130 supports the upper beam 110 and the inner side panel 120, which helps to enhance the overall rigidity of the body pillar assembly 100. The reinforcing member 130 can be set in the key stress area of ​​the body pillar assembly 100, thereby achieving local reinforcement of the body pillar assembly 100. This helps to improve the overall bending and torsional stiffness of the body and the bending mode, torsional mode, and local mode of the inner side panel 120. When the vehicle collides, the reinforcing member 130 can better disperse and absorb the energy generated by the collision, thereby reducing the deformation of the upper beam 110 and the inner side panel 120, which helps to protect the integrity of the passenger compartment, provide a safer survival space for the occupants, and thus improve the safety and reliability of the vehicle.

[0051] In addition, the reinforcement 130 also helps to enhance the durability of the body pillar assembly 100, reduce fatigue damage to the body pillar assembly 100 caused by long-term vibration, bumps and other factors, extend the service life of the body pillar assembly 100, and thus reduce the vehicle maintenance cost.

[0052] Furthermore, the reinforcing member 130 divides the mounting cavity into two smaller chambers, significantly increasing the moment of inertia of the body pillar assembly 100 and thus improving its resistance to deformation. Dividing the mounting cavity into two chambers also optimizes the force transmission path of the body pillar assembly 100, distributing the impact force more evenly across the structures of the two chambers. This prevents structural failure of the body pillar assembly 100 due to excessive local stress, further enhancing vehicle safety.

[0053] It should be noted that, compared to existing technologies, this embodiment of the application effectively improves the structural strength of the vehicle body pillar assembly 100 by simply installing a reinforcing member 130 within the mounting cavity, without needing to additionally increase the thickness of the upper beam 110 and the inner side panel 120. Furthermore, the reinforcing member 130 itself is relatively small, thus having little impact on the weight of the vehicle body pillar assembly 100. Therefore, the vehicle body pillar assembly 100 provided by this embodiment enhances the structural strength of the vehicle body pillar assembly 100 without adding excessive weight, ensuring vehicle lightweighting. This is beneficial for improving the vehicle's collision resistance while maintaining its environmental performance and handling performance, thereby enhancing the vehicle's safety and reliability.

[0054] See Figures 1 to 7As shown, in one possible implementation, the reinforcing member 130 of this application embodiment includes: a supporting body 131, a first connecting flange 132, and a second connecting flange 133, wherein the shape of the supporting body 131 is adapted to the cross-sectional shape of the mounting cavity; the first connecting flange 132 is disposed on a portion of the edge of the supporting body 131 facing the inner side panel 120, and the first connecting flange 132 is connected to the inner side panel 120; the second connecting flange 133 is disposed on a portion of the edge of the supporting body 131 facing the upper beam 110, and the second connecting flange 133 is connected to the upper beam 110.

[0055] It should be noted that, Figure 5 This is a schematic diagram showing the connection between the reinforcing member 130 and the inner side panel 120 in a downward direction from the outside of the vehicle towards the inside. Figure 7 This is a schematic diagram showing the connection between the reinforcing member 130 and the inner side panel 120 in the direction from the inside of the vehicle to the outside.

[0056] In its implementation, the reinforcing member 130 is connected to the inner side panel 120 and the upper side beam 110 via the first connecting flange 132 and the second connecting flange 133, respectively. This helps ensure the stability of the reinforcing member 130, thereby enhancing the overall structural strength of the body pillar assembly 100. Furthermore, this connection method allows the load to be distributed more evenly among the various components of the body pillar assembly 100, helping to avoid stress concentration and improving the load-bearing capacity and deformation resistance of the body pillar assembly 100.

[0057] Meanwhile, fixing via the first connecting flange 132 and the second connecting flange 133 also helps optimize the structural layout of the vehicle body pillar assembly 100, allowing the reinforcing member 130 to be better integrated into the entire vehicle body structure, ensuring structural strength without adversely affecting other functions and performance of the vehicle. The first connecting flange 132 and the second connecting flange 133 can be fixed to the inner side panel 120 and the upper side beam 110 by welding, bonding, or other methods. This application embodiment does not impose limitations on this, and appropriate choices can be made based on actual circumstances.

[0058] See Figure 2 , Figure 3 and Figure 4 As shown, in one possible implementation, there are multiple first connecting flanges 132 in this embodiment of the application, and the multiple first connecting flanges 132 are distributed at intervals along the circumferential direction of the supporting body 131.

[0059] Understandably, setting multiple first connecting flanges 132 can effectively distribute the load and prevent the inner side panel 120 from deforming or being damaged due to excessive stress at local connection points, which is beneficial to improving the stability and reliability of the body pillar assembly 100.

[0060] Meanwhile, the multiple first connecting flanges 132 are spaced apart, which helps to increase the contact area and connection strength between the reinforcing member 130 and the inner side panel 120, further improving the overall structural strength and deformation resistance of the body pillar assembly 100, and providing strong protection for the safety and durability of the vehicle.

[0061] Similarly, in this embodiment of the application, there are multiple second connecting flanges 133, which are distributed at intervals along the circumferential direction of the supporting body 131.

[0062] Thus, the multiple second connecting flanges 133 can prevent local stress concentration and deformation of the upper beam 110. At the same time, the multiple second connecting flanges 133 are distributed at intervals, which helps to increase the contact area between the reinforcing member 130 and the upper beam 110, improve the connection strength between the second connecting flanges 133 and the upper beam 110, and thus improve the structural strength of the body pillar assembly 100 and the vehicle's collision resistance.

[0063] See Figure 2 , Figure 3 and Figure 4 As shown, in one possible implementation, the support body 131 of this application embodiment is further provided with a connecting structure 1311, which is connected between two adjacent first connecting flanges 132, and the connecting structure 1311 protrudes toward the side of the second connecting flange 133.

[0064] Understandably, the connection structure 1311 between the two first connecting flanges 132 provides additional support and stability for the reinforcing member 130, which helps to enhance the structural integrity of the reinforcing member 130 itself and improve the connection strength between the reinforcing member 130 and the inner side panel 120. At the same time, it also helps to optimize the force transmission path of the body pillar assembly 100, so that the body pillar assembly 100 can distribute stress more evenly when bearing various loads, avoiding structural deformation or damage caused by local stress concentration.

[0065] In addition, the protrusion of the connecting structure 1311 toward the second connecting flange 133 can provide clearance space for the inner side panel 120, avoid interference between the connecting structure 1311 and the inner side panel 120, reduce the noise generated by the collision between the connecting structure 1311 and the inner side panel 120 when the body pillar assembly 100 is subjected to vibration and bumps, and further improve the driving experience of the vehicle.

[0066] See Figure 2 , Figure 3 , Figure 5 and Figure 7As shown, in one possible implementation, the first connecting flange 132 of this application embodiment is provided with a first connecting hole 1321, and the inner side panel 120 is provided with a second connecting hole (not shown in the figure). The first connecting flange 132 and the inner side panel 120 are connected by fasteners 1322 passing through the first connecting hole 1321 and the second connecting hole.

[0067] In some embodiments, the fastener 1322 can be a bolt, expansion screw, etc. This application embodiment does not limit this. By fixing the inner side panel 120 and the first connecting flange 132 together with the fastener 1322, the connection strength between the inner side panel 120 and the first connecting flange 132 can be guaranteed, and loosening or deformation at the connection point can be avoided. The operation is convenient and helps to improve the assembly efficiency of the vehicle body pillar assembly 100.

[0068] See Figure 2 , Figure 3 and Figure 6 As shown, in one possible implementation, the second connecting flange 133 of this application embodiment is welded to the upper beam 110.

[0069] This ensures the structural strength of key components of the vehicle body pillar assembly 100, and also prevents the vehicle body pillar assembly 100 from maintaining structural integrity under extreme conditions such as collisions, thus avoiding structural disintegration that could endanger the safety of occupants inside the vehicle and further improving the safety and reliability of the vehicle.

[0070] See Figure 2 , Figure 3 and Figure 4 As shown, in one possible implementation, the first connecting flange 132 and the second connecting flange 133 of this application embodiment extend toward both sides of the support body 131 along the thickness direction.

[0071] In some embodiments, the first connecting flange 132 and the second connecting flange 133 extend in opposite directions, so that the reinforcing member 130 can provide stable support and connection from multiple directions, which is beneficial to enhancing the structural strength of the body pillar assembly 100. At the same time, it is also beneficial to optimize the force transmission path. When the body pillar assembly 100 is impacted, the impact force can be more evenly distributed between the upper beam 110, the reinforcing member 130 and the side inner panel 120, avoiding excessive local pressure that could cause the force transmission path to fail. This is beneficial to ensuring the integrity of the passenger compartment inside the vehicle, thereby improving the safety and reliability of the vehicle.

[0072] See Figure 2 , Figure 3 and Figure 4As shown, in one possible implementation, the mounting cavity of this application embodiment includes chambers located on both sides of the reinforcing member 130, and the supporting body 131 is provided with an electrophoresis hole 1312 extending along its own thickness direction. The electrophoresis hole 1312 is used to connect the chambers on both sides of the mounting cavity.

[0073] In practical implementation, after assembling the upper beam 110, the inner side panel 120, and the reinforcing member 130, the surfaces of the upper beam 110, the inner side panel 120, and the reinforcing member 130 need to be electrophoretically treated to improve the corrosion resistance of the vehicle body pillar assembly 100, extend its service life, and improve the vehicle's aesthetics. Therefore, in this embodiment, an electrophoresis hole 1312 is provided on the reinforcing member 130. During electrophoresis treatment, the electrophoretic liquid in the mounting cavity can flow through the electrophoresis hole 1312 through the two chambers, thereby ensuring the uniformity of the electrophoretic coating. At the same time, the electrophoretic treatment of the inner walls of the two chambers can be completed with a single injection of electrophoretic liquid, which helps to improve the assembly efficiency of the vehicle body pillar assembly 100.

[0074] In addition, a positioning hole 1313 can be provided on the support body 131, which is used to position the reinforcing member 130.

[0075] In this way, when installing the reinforcing member 130, its position can be defined first by the positioning holes 1313, and then the reinforcing member 130 can be fixed together with the inner side panel 120 and the upper beam 110 by fasteners 1322 or welding. This helps to improve the assembly accuracy of the reinforcing member 130, reduce assembly errors, and improve assembly efficiency. Multiple positioning holes 1313 can be spaced apart to prevent the reinforcing member 130 from rotating during fixing, further improving installation accuracy. The specific number and position of the positioning holes 1313 are not limited in this embodiment and can be reasonably set according to the specific shape and size of the reinforcing member 130.

[0076] See Figure 1 As shown in the embodiment of this application, a vehicle is also provided, including any of the above-mentioned body pillar assemblies 100.

[0077] The structure and working principle of the vehicle body pillar assembly 100 have been described in detail in the above embodiments, and will not be repeated here.

[0078] In this embodiment of the application, by using the above-mentioned body pillar assembly 100, it is beneficial to improve the overall collision resistance of the vehicle without affecting the vehicle weight, improve the overall bending and torsional stiffness of the body and the bending mode, torsional mode and local mode of the side inner panel 120, thereby enhancing the safety and reliability of the vehicle.

[0079] In summary, this application provides a vehicle body pillar assembly 100 and a vehicle. The vehicle body pillar assembly 100 includes a side inner panel 120, an upper side beam 110, and a reinforcing member 130. The side inner panel 120 and the upper side beam 110 together form an mounting cavity. The reinforcing member 130 is disposed in the mounting cavity and is connected to the side inner panel 120 and the upper side beam 110 through a first connecting flange 132 and a second connecting flange 133. On the one hand, the reinforcing member 130 provides support for the side inner panel 120 and the upper side beam 110, which helps to improve the overall rigidity and structural strength of the vehicle body pillar assembly 100. On the other hand, the reinforcing member 130 divides the mounting cavity into two smaller chambers, making the stress distribution of the vehicle body pillar assembly 100 more uniform, which helps to avoid local stress concentration leading to fracture, and further improves the structural strength and durability of the vehicle body pillar assembly 100. Therefore, by using the vehicle body pillar assembly 100 of this application embodiment, the collision resistance of the vehicle can be effectively improved, and the safety and reliability of the vehicle can be enhanced.
