Description

Technical Field

[0001] This application relates to the field of vehicle body technology, and in particular to a vehicle body side structure and vehicle. Background Technology

[0002] Currently, in traditional designs, the top of the B-pillar on the side of the vehicle body is usually connected to the roof side beam by overlapping or by an integrally formed connecting joint.

[0003] Although this connection method can achieve the connection between the B-pillar and the roof side beam, it still has shortcomings such as limited connection strength between the structures at the top of the B-pillar, which is not conducive to improving the rigidity of the side structure of the vehicle body and the overall safety performance. Utility Model Content

[0004] In view of this, this application aims to propose a vehicle body side structure to improve the rigidity of the vehicle body side structure and enhance the overall vehicle safety performance.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A vehicle body side structure includes a roof side beam and a B-pillar connected to the roof side beam at the top; The B-pillar is equipped with a B-pillar reinforcing tube, and a first connecting bracket is provided between the top cover side beam and the B-pillar; The upper part of the first connecting bracket is connected to the top cover side beam, and the lower part of the first connecting bracket has a main body part located inside the B-pillar, and connecting arms respectively provided on the front and rear sides of the main body part. The main body is connected to the B-pillar reinforcing tube, and the connecting arms on both sides extend obliquely downward relative to the main body and are respectively connected to the stop edge of the corresponding side door opening.

[0006] Furthermore, the upper part of the first connecting bracket extends to the top of the top cover side beam, or the upper part of the first connecting bracket extends to the top of the top cover side beam.

[0007] Furthermore, a hinge reinforcement plate is provided inside the B-pillar, and the bottom end of the B-pillar reinforcement tube is connected to the hinge reinforcement plate.

[0008] Furthermore, a second connecting bracket is connected to the top of the hinge reinforcement plate; The bottom end of the B-pillar reinforcing tube is connected to the hinge reinforcing plate through the second connecting bracket, and the bottom end of the B-pillar reinforcing tube is inserted into the connecting hole on the second connecting bracket.

[0009] Furthermore, it also includes an A-pillar that is connected at the top to the front end of the top cover side beam; The A-pillar is equipped with an A-pillar reinforcing tube, the top of which extends into the top cover side beam, and the top of the A-pillar reinforcing tube is connected to the first connecting bracket.

[0010] Furthermore, viewed from the vertical direction of the entire vehicle, the top of the A-pillar reinforcing tube extends to the rear side of the B-pillar.

[0011] Furthermore, the top end of the B-pillar reinforcing tube extends upward to connect with the A-pillar reinforcing tube.

[0012] Furthermore, the bottom end of the A-pillar reinforcing tube extends to the rear end near the upper side beam of the cabin, and the bottom of the A-pillar reinforcing tube is connected to the A-pillar through a third connecting bracket.

[0013] Furthermore, a gap is formed between the third connecting bracket and the inner wall of the A-pillar; and / or, The cross-section of the A-pillar reinforcing tube is triangular.

[0014] Compared with related technologies, this application has the following advantages: (1) The side structure of the vehicle body described in this application is provided with a first connecting bracket between the roof side beam and the B-pillar, so that the upper part of the first connecting bracket is connected to the roof side beam and the lower main body of the first connecting bracket is connected to the B-pillar reinforcing tube. At the same time, the connecting arms on both sides are connected to the stop edges of the front and rear door openings. In this way, the connecting effect of the first connecting bracket can be used to increase the connection strength between the structures at the top of the B-pillar, thereby helping to improve the rigidity of the side structure of the vehicle body and improve the safety performance of the whole vehicle.

[0015] (2) The upper part of the first connecting bracket extends to the top of the roof side beam, or the upper part of the first connecting bracket extends to the top of the roof side beam. With the first connecting bracket provided, the first connecting bracket can provide better support for the upper part of the roof side beam and the roof position in the vehicle body, which helps to improve the roof's resistance to top pressure.

[0016] (3) A hinge reinforcement plate is installed inside the B-pillar, and the bottom end of the B-pillar reinforcement tube is connected to the hinge reinforcement plate. On the one hand, the hinge reinforcement plate can be used to increase the structural strength of the B-pillar and increase the reliability of the door hinge connection on the B-pillar. On the other hand, it can also facilitate the connection and arrangement of the B-pillar reinforcement tube inside the B-pillar and increase the stability of the B-pillar reinforcement tube inside the B-pillar, ensuring the reinforcement effect of the B-pillar reinforcement tube on the B-pillar position.

[0017] (4) By setting a second connecting bracket at the top of the hinge reinforcement plate, the bottom end of the B-pillar reinforcement tube is connected to the hinge reinforcement plate through the second connecting bracket. At the same time, the bottom end of the B-pillar reinforcement tube is inserted into the connecting hole on the second connecting bracket. This not only facilitates the connection between the B-pillar reinforcement tube and the hinge reinforcement plate and reduces the design and molding difficulty of the hinge reinforcement plate, but also increases the connection strength between the B-pillar reinforcement tube and the second connecting bracket by using the insertion connection between the B-pillar reinforcement tube and the second connecting bracket. This helps to improve the stability of the overall structure composed of the B-pillar, the hinge reinforcement plate, the second connecting bracket and the B-pillar reinforcement tube, and is beneficial to improving the stiffness of the B-pillar position and the collision force transmission performance.

[0018] (5) An A-pillar reinforcing tube is installed inside the A-pillar, and the top of the A-pillar reinforcing tube extends into the roof side beam and is connected to the first connecting bracket. The A-pillar reinforcing tube can be used to increase the structural strength of the A-pillar position and improve the collision force transmission performance of the A-pillar position. At the same time, the top of the A-pillar reinforcing tube extends to the first connecting bracket, which can also make the first connecting bracket limit the A-pillar reinforcing tube, so as to prevent the A-pillar reinforcing tube from moving too far back during the collision, causing the A-pillar to bend and deform, and encroaching on the passenger compartment space, which is conducive to improving the safety of the vehicle's frontal collision.

[0019] (6) The top of the A-pillar reinforcing tube extends to the rear side of the B-pillar, which not only allows the collision force at the A-pillar reinforcing tube to be fully transmitted to the rear along the roof side beam during a vehicle collision, but also combines with the transmission of the collision force at the A-pillar reinforcing tube to the B-pillar, thus better improving the transmission and dispersion effect of the collision force and improving collision safety. At the same time, the A-pillar reinforcing tube can also be used to extend further to the rear of the roof side beam, increasing the structural strength of the roof side beam, which helps to better improve the rigidity of the side of the vehicle body and improve the vehicle body's resistance to roof pressure.

[0020] (7) By extending the top of the B-pillar reinforcing tube upward to connect with the A-pillar reinforcing tube, the connection strength between the structures at the top of the B-pillar can be further increased by utilizing the direct connection between the A-pillar reinforcing tube and the B-pillar reinforcing tube, based on the connection of the first connecting bracket to the B-pillar reinforcing tube and the A-pillar reinforcing tube respectively. This helps to better improve the rigidity of the side structure of the vehicle body and improve the ability to transmit collision force between the A-pillar and the B-pillar.

[0021] (8) The bottom end of the A-pillar reinforcing tube extends to the rear end of the upper side beam of the engine compartment. When the vehicle is in a frontal collision, the collision force at the upper side beam of the engine compartment can be transferred to the A-pillar, especially the A-pillar reinforcing tube inside the A-pillar. This can improve the continuity of the collision force transmission channel and enhance the collision force transmission effect. The bottom of the A-pillar reinforcing tube is connected to the A-pillar through the third connecting bracket, which facilitates the connection and arrangement of the bottom of the A-pillar reinforcing tube inside the A-pillar. It also helps to increase the stability of the A-pillar reinforcing tube inside the A-pillar and ensure the reinforcement effect of the A-pillar reinforcing tube.

[0022] (9) A gap is formed between the third connecting bracket and the inner wall of the A-pillar, which not only facilitates the flow of electrophoretic liquid at the A-pillar position during the electrophoresis of the vehicle body and ensures the electrophoresis effect at the A-pillar position, but also helps to avoid abnormal noise at the A-pillar position when the vehicle vibrates. On the other hand, it also allows the third connecting bracket and the A-pillar to form multiple cavity structures, which can better increase the structural strength of the A-pillar itself.

[0023] This design allows the A-pillar reinforcing tube to have a triangular cross-section, which, while matching the A-pillar profile and resulting in a larger cross-sectional size, leverages the high strength of the triangular structure to further enhance its structural strength. This improves the reinforcing effect of the A-pillar reinforcing tube on the A-pillar structure and its ability to transmit impact forces at the A-pillar position, thereby improving the overall quality of the A-pillar structure.

[0024] Another object of this application is to provide a vehicle having the body side structure described above.

[0025] The advantages of the vehicle described in this application compared to related technologies are the same as those of the aforementioned vehicle body side structure, and will not be repeated here. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0031] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0032] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0033] The first aspect of this application provides a vehicle side structure, which mainly involves structural improvements to the side roof beam 1, B-pillar 2 and A-pillar 3 of the vehicle body. The vehicle side structure of this embodiment, through its innovative structural design, helps to improve the rigidity of the vehicle side structure and is beneficial to the improvement of the overall vehicle safety performance.

[0034] In related technologies, the B-pillar 2 position on the side of the vehicle body, especially the top of the B-pillar 2 position, is one of the important load-bearing parts of the vehicle body.

[0035] In traditional vehicle body design, the top of the B-pillar 2 is typically connected to the roof side beam 1 via an overlapping method or a one-piece molded connector. While existing connection methods can achieve the connection between the B-pillar 2 and the roof side beam 1, the connection strength between the structures at the top of the B-pillar 2 on the side of the vehicle is limited because both are usually stamped thin-walled sheet metal parts. This limits the overall structural rigidity of the vehicle body and is detrimental to improving the overall safety performance of the vehicle.

[0036] In view of this, in order to overcome the shortcomings of related technologies, the vehicle side structure of this embodiment combines... Figures 1 to 12 As shown, the overall design includes a top cover side beam 1 and a B-column 2 connected to the top cover side beam 1.

[0037] Among them, a B-pillar reinforcing tube 5 is installed inside the B-pillar 2, and a first connecting bracket 7 is also installed between the top cover side beam 1 and the B-pillar 2.

[0038] The upper part of the first connecting bracket 7 is connected to the top cover side beam 1, and the lower part of the first connecting bracket 7 has a main body 701 located in the B-pillar 2, and connecting arms 702 respectively provided on the front and rear sides of the main body 701.

[0039] The main body 701 is connected to the B-pillar reinforcing tube 5 located in the B-pillar 2, and the two connecting arms 702 extend obliquely downward relative to the main body 701 and are connected to the stop edge 200 of the corresponding side door opening 100 respectively.

[0040] Therefore, as described above, by setting a first connecting bracket 7 between the roof side beam 1 and the B-pillar 2, the upper part of the first connecting bracket 7 is connected to the roof side beam 1, and the lower main body 701 of the first connecting bracket 7 is connected to the B-pillar reinforcing tube 5, and the connecting arms 702 on both sides are connected to the stop edges 200 of the front and rear side door openings 100. This embodiment can utilize the connecting effect of the first connecting bracket 7 to increase the connection strength between the structures at the top of the B-pillar 2, thereby achieving the effect of improving the rigidity of the side structure of the vehicle body and improving the overall vehicle safety performance.

[0041] Based on the above overall introduction, specifically, it is worth noting that it still needs to be combined with... Figure 1 and Figure 2 As shown in the illustration, given that the B-pillar reinforcing tube 5 and the column reinforcing tube 6 described below are generally connected and installed on the B-pillar reinforcing plate and the A-pillar reinforcing plate, therefore, in Figure 1 and Figure 2 The accompanying drawings only show the A-pillar reinforcement plate, B-pillar reinforcement plate, roof side beam reinforcement plate, and sill reinforcement plate. For the inner A-pillar panel, inner B-pillar panel, inner roof side beam panel, and inner sill panel typically included in A-pillar 3, B-pillar 2, roof side beam 1, and sill beam 4, please refer to the relevant structures in existing vehicle bodies; they will not be described further here.

[0042] Furthermore, similar to the existing door opening structure on the side of the vehicle body, for the door opening 100 in this embodiment, the door opening 100 on the front side of B-pillar 2, that is, the front door opening, is generally formed by A-pillar 3, roof side beam 1, B-pillar 2 and sill beam 4, and the door opening 100 on the rear side of B-pillar 2, that is, the rear door opening, is generally formed by B-pillar 2, roof side beam 1, C-pillar (not shown in the figure) and sill beam 4.

[0043] Meanwhile, for the above-mentioned flange edges 200 of the front and rear door openings 100, the flange edge 200 at the position of the front door opening 100 is specifically also formed by splicing flange structures formed at the edges of the A-pillar reinforcement plate, roof side rail reinforcement plate, B-pillar reinforcement plate and sill beam reinforcement plate, and the flange edge 200 at the position of the rear door opening 100 is specifically formed by splicing flange structures formed at the edges of the B-pillar reinforcement plate, roof side rail reinforcement plate, C-pillar reinforcement plate and sill beam reinforcement plate.

[0044] Moreover, in addition to the flange structures on the above-mentioned reinforcement plates, of course, flange structures are also formed at the edges of the A-pillar inner panel, B-pillar inner panel, roof side rail inner panel, sill inner panel, etc. These flange structures on the inner panels are also spliced together, and together with the flange structures on the above-mentioned reinforcement plates form the flange edge 200 at the position of the door opening 100. Wherein, when both the reinforcement plate and the inner panel have flange structures, and they together form the flange edge 200, it can be understood that the connecting arm 702 of the above-mentioned first connecting bracket 7 connected to the flange edge 200 can be located between the flange structure on the reinforcement plate and the flange structure on the inner panel.

[0045] In addition, it is also worth noting that in this embodiment, based on the lower part of the first connecting bracket 7 comprising a central main body portion 701 and connecting arms 702 respectively arranged on the front and rear sides of the main body portion 701, and both connecting arms 702 on both sides extend obliquely downward relative to the main body portion 701, which makes the overall first connecting bracket 7 similar to a "wood" shaped structure. Thus, by using this "wood" shaped design, this embodiment can realize the connection between the first connecting bracket 7 and the surrounding roof side rail 1, B-pillar reinforcing tube 5, the flange edge 200 of the front and rear door openings 100 and the following A-pillar reinforcing tube 6, etc., so as to achieve the effect of improving the connection strength between structures at the top position of the B-pillar 2.

[0046] In this embodiment, continuing with reference to Figures 4 to 6 as shown, in some exemplary embodiments, based on the upper part of the first connecting bracket 7 being connected into the roof side rail 1, for example, the upper part of the first connecting bracket 7 can be extended to the top of the roof side rail 1, or the upper part of the first connecting bracket 7 can be extended to be close to the top of the roof side rail 1.

[0047] Thus, by extending the upper part of the first connecting bracket 7 to the top of the roof side rail 1, or extending the upper part of the first connecting bracket 7 to be close to the top of the roof side rail 1, it can be understood that on the basis of providing the first connecting bracket 7, this embodiment enables the first connecting bracket 7 to provide good supporting effect for the upper part of the roof side rail 1 and the roof position in the vehicle body, thereby helping to improve the roof crush resistance of the vehicle body.

[0048] For specific implementation, it is worth noting that still referring to Figure 6As shown, the upper part of the first connecting bracket 7 extends to the top of the roof side beam 1, that is, the top of the first connecting bracket 7 is flush with the top of the roof side beam 1. The upper part of the first connecting bracket 7 extends close to the top of the roof side beam 1, which means that there is a certain distance between the top of the first connecting bracket 7 and the top of the roof side beam 1. However, this distance is small and can enable the first connecting bracket 7 to provide good support for the roof side beam 1 and the vehicle roof connected to the roof side beam 1.

[0049] Additionally, as an exemplary embodiment, to ensure that the upper part of the first connecting bracket 7 extends towards the top of the top cover side beam 1, see also... Figure 4 and Figure 5 As shown, for example, an overhanging overlapping edge 703 can be formed on the upper part of the first connecting bracket 7. The overlapping edge 703 can generally be set as multiple overlapping edges distributed at intervals, and the length of each overlapping edge 703 can be determined based on the specific design, so that the top of each overlapping edge 703 is flush with the top of the top cover edge beam 1, or at a certain distance.

[0050] In this embodiment, the following continues... Figures 1 to 3 and combined Figure 8 As shown, in some exemplary embodiments, a hinge reinforcement plate 8 may be provided inside the B-pillar 2, such that the bottom end of the B-pillar reinforcement tube 55 is connected to the hinge reinforcement plate 8.

[0051] At this point, by setting a hinge reinforcement plate 8 inside the B-pillar 2 and connecting the bottom end of the B-pillar reinforcement tube 5 to the hinge reinforcement plate 8, it can be understood that this embodiment can, on the one hand, increase the structural strength of the B-pillar 2 and the reliability of the door hinge connection on the B-pillar 2 by utilizing the hinge reinforcement plate 8. On the other hand, this embodiment can obviously also facilitate the connection and arrangement of the B-pillar reinforcement tube 5 inside the B-pillar 2 and increase the stability of the B-pillar reinforcement tube 5 inside the B-pillar 2, thus helping to ensure the reinforcement effect of the B-pillar reinforcement tube 5 on the B-pillar 2.

[0052] In practical implementation, the aforementioned hinge reinforcement plate 8 can be made of stamped sheet metal, and it can extend along the height direction of the B-pillar 2 with a "U" shaped cross-section to give the hinge reinforcement plate 8 good structural strength and facilitate its connection arrangement within the B-pillar 2. The hinge reinforcement plate 8 is generally fixed to the B-pillar 2 by welding, and specifically connected to the B-pillar reinforcement plate in the B-pillar 2.

[0053] Based on the aforementioned hinge reinforcement plate 8, this embodiment continues to combine... Figure 8As shown, in some exemplary embodiments, the top of the hinge reinforcement plate 8 may be connected to a second connecting bracket 9, for example. Simultaneously, the bottom end of the B-pillar reinforcement tube 55 is also connected to the hinge reinforcement plate 8 via the second connecting bracket 9, and the bottom end of the B-pillar reinforcement tube 55 is inserted into a connecting hole 9a on the second connecting bracket 9.

[0054] At this time, by setting a second connecting bracket 9 on the top of the hinge reinforcing plate 8, the bottom end of the B-pillar reinforcing tube 5 is connected to the hinge reinforcing plate 8 through the second connecting bracket 9, and the bottom end of the B-pillar reinforcing tube 5 is also inserted into the connecting hole on the second connecting bracket 9. It can be understood that this embodiment not only facilitates the connection between the B-pillar reinforcing tube 5 and the hinge reinforcing plate 8, but also reduces the design and molding difficulty of the hinge reinforcing plate 8.

[0055] At the same time, it is obvious that this embodiment can also utilize the insertion connection between the B-pillar reinforcing tube 5 and the second connecting bracket 9 to increase the connection strength between the B-pillar reinforcing tube 5 and the second connecting bracket 9, thereby improving the stability of the overall structure composed of the B-pillar 2, the hinge reinforcing plate 8, the second connecting bracket 9 and the B-pillar reinforcing tube 5, which is beneficial to improving the stiffness of the B-pillar 2 position and the collision force transmission performance.

[0056] In specific implementation, it is worth noting that the second connecting bracket 9 can also be made of sheet metal by stamping. Furthermore, based on the "U" shaped cross section of the hinge reinforcing plate 8, the second connecting bracket 9 can preferably be fixed inside the hinge reinforcing plate 8, and the two can generally be fixed together by welding.

[0057] Furthermore, the shape of the connecting hole 9a on the second connecting bracket 9 should match the cross-sectional shape of the bottom end of the B-pillar reinforcing tube 5. This design ensures that when the bottom end of the B-pillar reinforcing tube 5 is inserted into the connecting hole 9a, there is a clear gap between the outer wall of the B-pillar reinforcing tube 5 and the inner wall of the connecting hole 9a, facilitating the connection of the B-pillar reinforcing tube 5 and the second connecting bracket 9. The second connecting bracket 9 and the B-pillar reinforcing tube 5 are typically connected by welding.

[0058] Still Figures 1 to 3 As shown, in some exemplary embodiments, the vehicle side structure of this embodiment also includes an A-pillar 3 that is connected to the front end of the roof side beam 1 at the top.

[0059] Among them, an A-pillar reinforcing tube 6 is provided inside the A-pillar 3. The top of the A-pillar reinforcing tube 6 extends into the top cover side beam 1, and the top of the A-pillar reinforcing tube 6 is connected to the first connecting bracket 7.

[0060] Therefore, it can be understood that, based on the A-pillar reinforcing tube 6 installed inside the A-pillar 3, by extending the top of the A-pillar reinforcing tube 6 into the top cover side beam 1 and connecting it with the first connecting bracket 7, this embodiment can not only increase the structural strength of the A-pillar 3 position by using the A-pillar reinforcing tube 6, but also improve the collision force transmission performance of the A-pillar 3 position.

[0061] Meanwhile, in this embodiment, the top of the A-pillar reinforcing tube 6 extends to connect with the first connecting bracket 7, which also enables the first connecting bracket 7 to limit the A-pillar reinforcing tube 6. This can prevent the A-pillar reinforcing tube 6 from moving too far back during a frontal collision, causing the A-pillar 3 to bend and deform, encroaching on the passenger compartment space, and thus improving the safety of the vehicle in a frontal collision.

[0062] In specific implementation, based on the A-pillar reinforcing tube 6 installed inside the A-pillar 3, and given that the top of the A-pillar reinforcing tube 6 extends into the top cover side beam 1, in some exemplary embodiments, such as this embodiment... Figure 2 As indicated by the dashed line L, from the perspective of the vehicle's vertical direction, for example, the top of the A-pillar reinforcing tube 6 can extend to the rear side of the B-pillar 2.

[0063] In this way, the top of the A-pillar reinforcing tube 6 extends to the rear side of the B-pillar 2. It can be understood that this embodiment not only ensures that the impact force at the A-pillar reinforcing tube 6 is fully transmitted rearward along the roof side beam 1 during a vehicle collision, but also combines this with the transmission of the impact force from the A-pillar reinforcing tube 6 to the B-pillar 2, thereby better improving the force transmission and dispersion effect and enhancing collision safety. At the same time, this embodiment also obviously utilizes the extension of the A-pillar reinforcing tube 6 further towards the rear of the roof side beam 1, increasing the structural strength of the roof side beam 1, which helps to better improve the rigidity of the vehicle's side and enhance the vehicle's resistance to roof crush.

[0064] In practical implementation, it is worth noting that the length of the top of the A-pillar reinforcing tube 6 extending to the rear side of the B-pillar 2 can be selected according to specific design requirements, and there is no restriction on it. Those skilled in the art can determine this by comprehensively considering the strength requirements of the vehicle body structure and the cost of the vehicle body structure.

[0065] In this embodiment, in some exemplary implementations, the top end of the B-pillar reinforcing tube 55 may extend upward to connect with the A-pillar reinforcing tube 6.

[0066] At this point, by extending the top of the B-pillar reinforcing tube 5 upward to connect with the A-pillar reinforcing tube 6, this embodiment can further increase the connection strength between the structures at the top of the B-pillar 2 by utilizing the direct connection between the A-pillar reinforcing tube 6 and the B-pillar reinforcing tube 5, based on the connection of the first connecting bracket 7 to the B-pillar reinforcing tube 5 and the A-pillar reinforcing tube 6 respectively. This helps to better improve the rigidity of the side structure of the vehicle body and improve the ability to transmit collision force between the A-pillar 3 and the B-pillar 2.

[0067] In practical implementation, as an example, it remains the same. Figures 1 to 3 and combined Figure 6 As shown, for example, the top end of the B-pillar reinforcing tube 5 extending upward can be located inside the A-pillar reinforcing tube 6, and the B-pillar reinforcing tube 5 can be overlapped on the A-pillar reinforcing tube 6, and then the two can be connected together by welding.

[0068] The inner side of the aforementioned A-pillar reinforcing tube 6 is the side facing the passenger compartment. Furthermore, besides having the top of the B-pillar reinforcing tube 5 located inside the A-pillar reinforcing tube 6, in other feasible embodiments, the top of the B-pillar reinforcing tube 5 can be located outside the A-pillar reinforcing tube 6, i.e., the side facing outwards from the vehicle. This is also acceptable, as long as the arrangement requirements of the A-pillar reinforcing tube 6 and the B-pillar reinforcing tube 5 are met, and a reliable connection between them can be achieved.

[0069] In this embodiment, for example... Figure 2 As shown, in some exemplary embodiments, the bottom end of the aforementioned A-pillar reinforcing tube 6 may extend to the rear end near the upper side beam 13 of the cabin, and the bottom of the A-pillar reinforcing tube 6 is also connected to the A-pillar 3 via a third connecting bracket 10.

[0070] At this point, the bottom end of the A-pillar reinforcing tube 6 extends to the rear end near the upper side beam 13 of the engine compartment. Obviously, this embodiment can facilitate the transmission of the collision force at the upper side beam 13 of the engine compartment to the A-pillar 3, especially the A-pillar reinforcing tube 6 inside the A-pillar 3, during a frontal collision of the vehicle, thereby improving the permeability of the collision force transmission channel and enhancing the collision force transmission effect.

[0071] The bottom of the A-pillar reinforcing tube 6 is connected to the A-pillar 3 through the third connecting bracket 10, which facilitates the connection and arrangement of the bottom of the A-pillar reinforcing tube 6 within the A-pillar 3 and also helps to increase the stability of the A-pillar reinforcing tube 6 within the A-pillar 3, so as to ensure the reinforcing effect of the A-pillar reinforcing tube 6.

[0072] In specific implementation, combined with Figure 9 As shown, the third connecting bracket 10 can be a stamped sheet metal structure, and the third connecting bracket 10 can also extend along the length direction of the A-pillar 3, thus providing connection and support for the A-pillar reinforcing tube 6 over a larger length.

[0073] Furthermore, based on the arrangement of the third connecting bracket 6 within the A-pillar 3, in some exemplary embodiments, it is still provided by... Figure 10 As shown, in this embodiment, a gap s may also be formed between the third connecting bracket 10 and the inner wall of the A column 3.

[0074] At this time, by forming a gap s between the third connecting bracket 10 and the inner wall of the A-pillar 3, it can be understood that it not only facilitates the flow of electrophoretic liquid at the A-pillar 3 position during the electrophoresis of the car body, but also ensures the electrophoresis effect at the A-pillar 3 position.

[0075] Meanwhile, through the gap s formed between the third connecting bracket 10 and the inner wall of the A-pillar 3, this embodiment helps to avoid abnormal noise at the A-pillar 3 position when the vehicle vibrates, and also enables the third connecting bracket 10 and the A-pillar 3 to form multiple cavity structures, which can better increase the structural strength of the A-pillar 3 itself.

[0076] In this embodiment, please continue to refer to... Figure 10 As shown, in some exemplary embodiments, the cross-section of the aforementioned A-pillar reinforcing tube 6 may be triangular, for example.

[0077] It is worth noting that the cross-section of the aforementioned A-pillar reinforcing tube 6 is triangular, which generally refers to... Figure 10 As shown, the cross-section of the A-pillar reinforcing tube 6 is triangular overall, but not strictly a triangle. That is, within the triangular cross-section of the A-pillar reinforcing tube 6, for example, the vertices may have rounded transitions, or one side of the triangular cross-section may be slightly curved, etc.

[0078] Furthermore, by making the cross-section of the A-pillar reinforcing tube 6 triangular, it can be understood that this embodiment can, on the basis of matching the A-pillar 3 profile and making the cross-sectional size of the A-pillar reinforcing tube 6 large, utilize the high strength of the triangular structure to further increase the structural strength of the A-pillar reinforcing tube 6, thereby improving the reinforcing effect of the A-pillar reinforcing tube 6 on the A-pillar 3 structure and enhancing the transmission effect of the A-pillar reinforcing tube 6 on the collision force at the A-pillar 3 position, so as to improve the overall structural quality of the A-pillar 3.

[0079] It is worth noting that, regarding the vehicle side structure of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 12 As shown, it may include, for example, a top cover side beam 1, a B-column 2 connected to the top of the top cover side beam 1, and an A-column 3 connected to the front end of the top of the top cover side beam 1.

[0080] The B-pillar 2 is equipped with a B-pillar reinforcing tube 5, and a first connecting bracket 7 is provided between the roof side beam 1 and the B-pillar 2. The upper part of the first connecting bracket 7 is connected to the roof side beam 1, and the lower part of the first connecting bracket 7 has a main body 701 located inside the B-pillar 2, and connecting arms 702 respectively provided on the front and rear sides of the main body 701. The main body 701 is connected to the B-pillar reinforcing tube 5, and the two connecting arms 702 on both sides extend obliquely downward relative to the main body 701 and are respectively connected to the stop edge 200 of the corresponding side door opening 100.

[0081] The upper part of the first connecting bracket 7 extends to the top of the top cover side beam 1. A hinge reinforcing plate 8 is provided inside the B-pillar 2. The top of the hinge reinforcing plate 8 is connected to a second connecting bracket 9. The bottom end of the B-pillar reinforcing tube 5 is connected to the hinge reinforcing plate 8 through the second connecting bracket 9, and the bottom end of the B-pillar reinforcing tube 5 is inserted into the connecting hole 9a on the second connecting bracket 9.

[0082] In addition, an A-pillar reinforcing tube 6 is provided inside the A-pillar 3. The top of the A-pillar reinforcing tube 6 extends into the roof side beam 1, and the top of the A-pillar reinforcing tube 6 is connected to the first connecting bracket 7. At the same time, viewed from the vertical direction of the whole vehicle, the top of the A-pillar reinforcing tube 6 extends to the rear side of the B-pillar 2, and the top of the B-pillar reinforcing tube 5 also extends upward to connect with the A-pillar reinforcing tube 6.

[0083] In addition, the bottom end of the A-pillar reinforcing tube 6 extends to the rear end near the upper side beam 13 of the cabin, and the bottom of the A-pillar reinforcing tube 6 is connected to the A-pillar 3 through the third connecting bracket 10. At the same time, a gap s is formed between the third connecting bracket 10 and the inner wall of the A-pillar 3, and the cross-section of the A-pillar reinforcing tube 6 is triangular.

[0084] In the preferred embodiment of the above-mentioned vehicle body side structure, the specific configuration and arrangement of the B-pillar reinforcing tube 5, A-pillar reinforcing tube 6, hinge reinforcing plate 8 and various connecting brackets can still be referred to the descriptions in the above-mentioned exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the B-pillar reinforcing tube 5, A-pillar reinforcing tube 6, hinge reinforcing plate 8 and various connecting brackets can also be referred to the descriptions in the above-mentioned exemplary embodiments.

[0085] In addition, in the specific manufacturing process, the aforementioned A-pillar reinforcing tube 6 and B-pillar reinforcing tube 5 can be hot-expansion tubes, and each of the aforementioned connecting brackets can be a stamped sheet metal structure. Furthermore, each connecting bracket is generally connected to the A-pillar 3, B-pillar 2, or top cover side beam 1 by welding.

[0086] Furthermore, to facilitate the connection between the first connecting bracket 7 and the A-pillar reinforcing tube 6 and the B-pillar reinforcing tube 5, a first groove 7a and a second groove 7b can be formed on the first connecting bracket 7, wherein the A-pillar reinforcing tube 6 can be embedded in the first groove 7a and the B-pillar reinforcing tube 5 can be embedded in the second groove 7b, so that the first connecting bracket 7 partially wraps around each reinforcing tube, which not only facilitates their connection but also increases the reliability of their connection.

[0087] In addition, besides the arrangement of the first connecting bracket 7, the hinge reinforcing plate 8, the second connecting bracket 9 and the third connecting bracket 10 described above, in order to improve the stability of the arrangement of the A-pillar reinforcing tube 6 in the A-pillar 3 and the stability of the arrangement of the B-pillar reinforcing tube 5 in the B-pillar 2, a fourth connecting bracket 11 may of course be arranged in the B-pillar 2, and a fifth connecting bracket 12 may be arranged in the A-pillar 3.

[0088] in combination with Figure 11 and Figure 12 as shown in the figures, based on the profile characteristics of the B-pillar 2 and the A-pillar 3, the fourth connecting bracket 11 may, for example, be an Ω-shaped structure, and the fifth connecting bracket 12 may be generally in an n-shaped structure with a flange at one end. Moreover, the fourth connecting bracket 11 can be fixedly connected in the B-pillar 2 by welding, and it only needs to connect with the B-pillar reinforcing tube 5 while partially wrapping the B-pillar reinforcing tube 5. Similarly, the fifth connecting bracket 12 is also fixedly connected in the A-pillar 3 by welding, and it only needs to connect with the A-pillar reinforcing tube 6 while partially wrapping the A-pillar reinforcing tube 6.

[0089] With the above design, the vehicle body side structure of the present embodiment provides the first connecting bracket between the roof side rail and the B-pillar, such that the upper part of the first connecting bracket is connected to the interior of the roof side rail, the main body part at the lower part of the first connecting bracket is connected with the B-pillar reinforcing tube, and the connecting arms on both sides are connected with the seam edges of the front and rear door openings. In this way, the connecting effect of the first connecting bracket can be utilized to increase the connection strength between the structures at the top of the B-pillar, which further helps improve the stiffness of the vehicle body side structure and enhance the safety performance of the entire vehicle.
