Description

Technical Field

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

[0002] The safety and stability of the vehicle body structure are key indicators for evaluating vehicle body performance. As the primary area for resisting side impacts, the structural strength of the vehicle's sides plays a crucial role in the vehicle's integrity. Reinforcement structures are typically installed in areas such as the A-pillars, B-pillars, and door sill beams to effectively enhance the vehicle body's resistance to deformation.

[0003] In related technologies, the A-pillar, B-pillar, and sill beam on the side of the vehicle body are reinforced with sheet metal reinforcement plates. However, using sheet metal reinforcement plates as a reinforcement structure limits the reinforcement effect on the side of the door, which is not conducive to improving the overall vehicle collision safety. Utility Model Content

[0004] In view of this, this application aims to propose a vehicle side structure to improve the overall vehicle collision safety.

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

[0006] A vehicle body side structure includes an A-pillar, a B-pillar, a sill beam connected to the bottom of both the A-pillar and the B-pillar, and a first reinforcing member;

[0007] The first reinforcing member is L-shaped and includes a connected vertical portion and a horizontal portion;

[0008] The vertical portion is located within the lower section of the A-pillar, and the top of the vertical portion extends to near the top of the lower section. The horizontal portion is located within the sill beam, and the rear end of the horizontal portion extends to near the bottom of the B-pillar.

[0009] Furthermore, both the vertical portion and the horizontal portion adopt a tubular structure, and the inner cavities of the vertical portion and the horizontal portion are connected.

[0010] Furthermore, the first reinforcing member is integrally formed, and the first reinforcing member adopts a hot air expansion tube.

[0011] Furthermore, both the vertical portion and the horizontal portion have rectangular cross-sections; and / or, the cross-section of the vertical portion is larger than that of the horizontal portion, and the connection position between the vertical portion and the horizontal portion forms a transition section with a gradually changing cross-section.

[0012] Furthermore, the vertical portion is fixed within the lower section by a first connecting bracket; and / or, the horizontal portions are all fixed within the sill beam by second connecting brackets, and the second connecting brackets are multiple brackets spaced apart along the extension direction of the horizontal portions.

[0013] Furthermore, the side structure of the vehicle body also includes a roof side beam connecting the upper section of the A-pillar to the top of the B-pillar, and a second reinforcing member; the second reinforcing member is "n"-shaped, and the second reinforcing member includes a first part located in the upper section, a second part located in the roof side beam, and a third part located in the B-pillar.

[0014] Furthermore, the second reinforcing member is integrally formed, and the second reinforcing member adopts a hot air expansion tube.

[0015] Furthermore, the first part is fixed inside the upper section by the third connecting bracket, the second part is fixed inside the top cover side beam by the fourth connecting bracket, and the third part is fixed inside the B-pillar by the fifth connecting bracket.

[0016] Furthermore, the third connecting bracket is arranged near the bottom end of the first part and extends along the length direction of the first part; and / or, the fourth connecting bracket is a plurality of brackets arranged at intervals along the length direction of the second part; and / or, the B-pillar is provided with a hinge mounting plate, the fifth connecting bracket includes a lower bracket connected to the hinge mounting plate, the lower bracket is provided with a connecting hole, the bottom end of the third part is inserted into the connecting hole, and the bottom end of the third part is fixedly connected to the lower bracket.

[0017] Compared with related technologies, this application has the following advantages:

[0018] (1) The side structure of the vehicle body described in this application, by setting a first reinforcing member between the A-pillar and the sill beam, so that the top of the vertical part of the first reinforcing member extends to the top near the lower section, and the rear end of the horizontal part extends to the bottom near the B-pillar, can increase the connection strength between the A-pillar and the sill beam, and can also form a load-bearing structure and a through-type collision force transmission channel between the lower section of the A-pillar and the front part of the sill beam during side collisions and frontal collisions, can realize the effective transmission of collision force, can reduce the collision deformation at the A-pillar position, and is conducive to improving the safety of the whole vehicle collision.

[0019] (2) By making both the vertical and horizontal parts adopt tubular structures and connecting the inner cavities of the vertical and horizontal parts, the first reinforcing member can be made into a reinforcing tube structure as a whole. This not only facilitates the design and preparation of the first reinforcing member, but also utilizes the high strength of the tubular structure to ensure the reinforcing effect of the first reinforcing member.

[0020] (3) By setting the first reinforcing member to be integrally formed, it is convenient to prepare it and can also ensure the reliability of the connection between the vertical part and the horizontal part. At the same time, the first reinforcing member adopts hot air expansion tube, which is also convenient for the cross-sectional design and forming of the first reinforcing member with tubular structure, and also helps to ensure the structural performance of the first reinforcing member.

[0021] (4) By setting the cross-sections of the vertical and horizontal sections to be rectangular, the cross-sectional shapes of the A-pillar and sill beam can be adapted, facilitating the arrangement of the first reinforcing member in the A-pillar and sill beam. Furthermore, by making the cross-section of the vertical section larger than that of the horizontal section and forming a transition section with a gradual change in cross-section at the connection point between the two, the stiffness of the lower part of the A-pillar can be increased by focusing on the vertical section, thereby improving the collision bearing performance during a frontal collision. At the same time, the design of the transition section can also be used to facilitate the effective transfer of the collision force from the vertical section to the horizontal and vertical directions, thereby improving the collision force transfer effect.

[0022] (5) By fixing the vertical part to the lower section of the A-pillar through the first connecting bracket and fixing the horizontal part to the sill beam through the second connecting bracket, it is easy to fix the first reinforcing member in the A-pillar and the sill beam. Furthermore, by having multiple second connecting brackets arranged at intervals, the stability of the horizontal part in the sill beam can be guaranteed, and it also helps to improve the transmission effect of the collision force between the sill beam and the first reinforcing member.

[0023] (6) By setting a second reinforcing member in the upper section of the A-pillar, the roof side beam and the B-pillar, the structural strength between the A-pillar, B-pillar and the roof side beam can be increased by the second reinforcing member. At the same time, a roll cage structure can be formed between the upper parts of the A-pillar and B-pillar. This not only helps to distribute the collision force between the A-pillar and B-pillar, but also helps to improve the anti-top pressure performance of the side of the vehicle body, thus improving the collision safety of the whole vehicle.

[0024] (7) By making the second reinforcing member integrally formed, it is easier to manufacture and the reliability of the connection between the first and third parts can be guaranteed. At the same time, the use of hot gas expansion tubes for the second reinforcing member is also conducive to the cross-sectional design and forming of the second reinforcing member, and also helps to ensure the structural performance of the second reinforcing member.

[0025] (8) The first part is fixed in the upper section of the A column by the third connecting bracket, the second part is fixed in the top cover side beam by the fourth connecting bracket, and the third part is fixed in the B column by the fifth connecting bracket, which facilitates the fixed arrangement of the second reinforcing member in the A column, B column and top cover side beam.

[0026] (9) By arranging the third connecting bracket in the A-pillar close to the bottom of the first part and extending along the length of the first part, the fixation effect on the first part can be ensured, and the impact force at the A-pillar position can be transferred to the first part. Arranging multiple third connecting brackets at intervals can ensure the stability of the second part fixed in the top cover side beam. And by making the fifth connecting bracket in the B-pillar include a lower bracket connected to the hinge mounting plate, and by inserting the bottom of the third part into the connecting hole on the lower bracket and fixing it together with the lower bracket, the stability of the third part fixed in the B-pillar can be ensured, and the impact force of the second reinforcement can be transferred and dispersed to the B-pillar.

[0027] This application also proposes a vehicle having a body side structure as described above.

[0028] The vehicle described in this application, by having the side body structure as described above, helps to improve the overall collision safety of the vehicle. Attached Figure Description

[0046] To make the technical solution and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0049] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0050] 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.

[0051] 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.

[0052] The first aspect of this application provides a vehicle side structure, which mainly involves structural improvements at the A-pillar 1, B-pillar 2 and sill beam 3 positions on the vehicle side. Through innovative structural design, it can effectively improve the connection strength between the A-pillar 1, B-pillar 2 and sill beam 3, thereby improving the safety of the vehicle in side and frontal collisions.

[0053] In related technologies, the A-pillar 1, B-pillar 2, and sill beam 3 on the side of the vehicle body are reinforced with sheet metal reinforcement plates. Sheet metal reinforcement plates are usually made of thin metal sheets by stamping and bending. Due to the limited thickness of the sheet metal reinforcement plates, the impact area is prone to deformation or even tearing when subjected to high-intensity collisions.

[0054] Furthermore, because the sheet metal reinforcement plate has multiple bending angles between its structures during stamping and bending, stress concentration is likely to occur during a collision, which can hinder the transmission of impact energy. As a result, using sheet metal reinforcement plates as a body reinforcement structure has limited reinforcement effect on the side of the door, which is not conducive to improving the overall vehicle collision safety.

[0055] In view of this, in order to overcome the shortcomings of the related technology, the vehicle side structure of this embodiment combines... Figures 1 to 4As shown, the overall design includes A-pillar 1, B-pillar 2, a threshold beam 3 connected to the bottom of both A-pillar 1 and B-pillar 2, and a first reinforcing member 4.

[0056] The first reinforcing member 4 is L-shaped and includes a connected vertical portion 401 and a horizontal portion 402.

[0057] The vertical portion 401 is located within the lower section 101 of column A 1, and the top of the vertical portion 401 extends to near the top of the lower section 101. The horizontal portion 402 is located within the threshold beam 3, and the rear end of the horizontal portion 402 extends to near the bottom of column B 2.

[0058] Therefore, by setting a first reinforcing member 4 between the A-pillar 1 and the sill beam 3, the top of the vertical portion 401 of the first reinforcing member 4 extends to the top near the lower section 101, and the rear end of the horizontal portion 402 extends to the bottom near the B-pillar 2, this embodiment can not only increase the connection strength between the A-pillar 1 and the sill beam 3, but also form a load-bearing structure and a through-type collision force transmission channel between the lower section 101 of the A-pillar 1 and the front part of the sill beam 3 during side and frontal collisions of the vehicle, which can effectively transmit the collision force, reduce the collision deformation at the A-pillar 1 position, and thus improve the safety of the whole vehicle during a collision.

[0059] Based on the above overall introduction, specifically, it can be understood that, in combination with Figure 2 , Figure 4 and Figure 5 As shown, the first reinforcing member 4 is L-shaped, which mainly refers to the fact that the first reinforcing member 4 includes a vertical part 401 and a horizontal part 402 that are connected to each other. When the vertical part 401 and the horizontal part 402 are connected, they can be connected to the A-pillar 1 and the sill beam 3.

[0060] When viewed from the side of the vehicle, the first reinforcing member 4 is generally L-shaped or similar to L. The main purpose of the shape of the first reinforcing member 4 is to form a load-bearing structure and a through-type collision force transmission channel between the lower section 101 of the A-pillar 1 and the front part of the sill beam 3 during side and front collisions of the vehicle.

[0061] In some of the exemplary implementations, combined with Figure 4 As shown, both the vertical portion 401 and the horizontal portion 402 adopt a tubular structure, and the inner cavities of the vertical portion 401 and the horizontal portion 402 are connected.

[0062] Therefore, by making both the vertical portion 401 and the horizontal portion 402 adopt tubular structures, and with the inner cavities of the vertical portion 401 and the horizontal portion 402 connected, the first reinforcing member 4 can be made into a reinforced tubular structure as a whole. This not only facilitates the design and fabrication of the first reinforcing member 4, but also utilizes the high strength of the tubular structure to ensure the reinforcing effect of the first reinforcing member 4. At the same time, the tubular structure makes the first reinforcing member 4 itself have an energy-absorbing cavity. When the first reinforcing member 4 is impacted, the side wall of the first reinforcing member 4 that is impacted first deforms into the energy-absorbing cavity, thereby absorbing more impact energy and effectively reducing the impact energy transmitted to the other side of the first reinforcing member 4.

[0063] In specific implementation, the first reinforcing member 4 can be set to a seamless tubular structure, thereby making the overall strength of the first reinforcing member 4 uniform and consistent. When a collision occurs, it can effectively avoid the stress concentration caused by the splicing seam of the tube body, so that the first reinforcing member 4 maintains good structural strength and deformation resistance.

[0064] In some of the exemplary implementations, combined with Figure 4 As shown, the first reinforcing member 4 is integrally formed and adopts a hot-expansion tube. By setting the first reinforcing member 4 to be integrally formed, it is easier to manufacture and can also ensure the reliability of the connection between the vertical part 401 and the horizontal part 402. At the same time, the use of a hot-expansion tube for the first reinforcing member 4 can also facilitate the cross-sectional design and forming of the tubular structure of the first reinforcing member 4, and also help to ensure the structural performance of the first reinforcing member 4.

[0065] It is understandable that the integral molding of the first reinforcing member 4 allows the vertical part 401 and the horizontal part 402 to be naturally connected, which facilitates the smooth transmission of the impact force along the first reinforcing member 4 and can effectively avoid cracking of the vertical part 401 and the horizontal part 402 due to welding or riveting, thereby effectively avoiding the failure of impact force transmission.

[0066] It is worth noting that hot gas expansion tube is a manufacturing process that uses high-temperature and high-pressure gas to expand and form metal tubes. In specific implementation, by setting the first reinforcing member 4 to use hot gas expansion tube, the first reinforcing member 4 can be uniformly deformed in the forming mold during forming, which is conducive to adjusting the tube wall thickness of the first reinforcing member 4. In the event of a collision, it can effectively ensure the continuity of the collision force transmission path. Furthermore, using hot gas expansion tube for the first reinforcing member 4 is beneficial to conforming the inner cavity shape of the A-pillar 1 and the inner cavity shape of the sill beam 3.

[0067] In some of the exemplary implementations, combined with Figure 4 and Figure 5As shown, the cross-sections of both the vertical portion 401 and the horizontal portion 402 are rectangular; the cross-section of the vertical portion 401 is larger than that of the horizontal portion 402, and a transition section 403 with a gradually changing cross-section is formed at the connection position between the vertical portion 401 and the horizontal portion 402.

[0068] Therefore, by setting the cross-sections of the vertical portion 401 and the horizontal portion 402 to be rectangular, the cross-sectional shapes of the A-pillar 1 and the sill beam 3 can be adapted, facilitating the arrangement of the first reinforcing member 4 in the A-pillar 1 and the sill beam 3. By making the cross-section of the vertical portion 401 larger than that of the horizontal portion 402, and forming a transition section 403 with a gradually changing cross-section at the connection point between the two, the vertical portion 401 can be used to significantly increase the stiffness of the lower part of the A-pillar 1, improving the collision bearing performance during a frontal collision. At the same time, the design of the transition section 403 can also be used to effectively transfer the collision force at the vertical portion 401 to the horizontal and vertical directions, improving the collision force transmission effect.

[0069] In some of the exemplary implementations, combined with Figures 4 to 7 As shown, the vertical portion 401 is fixed in the lower section 101 by the first connecting bracket 4011; the horizontal portions 402 are all fixed in the threshold beam 3 by the second connecting bracket 4021, and the second connecting bracket 4021 consists of multiple brackets arranged at intervals along the extension direction of the horizontal portions 402.

[0070] As described above, by fixing the vertical part 401 to the lower section 101 of the A-pillar 1 via the first connecting bracket 4011, and by fixing the horizontal part 402 to the sill beam 3 via the second connecting bracket 4021, it is easy to fix the first reinforcing member 4 in the A-pillar 1 and the sill beam 3. Furthermore, by having multiple second connecting brackets 4021 arranged at intervals, the stability of the horizontal part 402 in the sill beam 3 can be ensured, which also helps to improve the transmission of collision force between the sill beam 3 and the first reinforcing member 4.

[0071] In specific implementation, continue to combine Figures 4 to 7 As shown, since the A-pillar 1 has a cavity inside, the A-pillar 1 includes an outer A-pillar panel located outside the vehicle and an inner A-pillar panel located inside the vehicle. The vertical portion 401 can be fixed to the outer A-pillar panel of the lower section 101 via the first connecting bracket 4011, or it can be fixed to the inner A-pillar panel of the lower section 101 via the first connecting bracket 4011. Preferably, in this embodiment, the vertical portion 401 is fixed to the outer A-pillar panel of the lower section 101 via the first connecting bracket 4011.

[0072] Similar to the structure of A-pillar 1, the sill beam 3 also has an internal cavity, thus making the sill beam 3 include an outer sill beam plate and an inner sill beam plate. The transverse portion 402 can be fixed to the outer sill beam plate or the inner sill beam plate via the second connecting bracket 4021. Preferably, in this embodiment, the transverse portion 402 is fixed to the inner sill beam plate via the second connecting bracket 4021.

[0073] It is worth noting that, as a specific configuration of the first connecting bracket 4011, the first connecting bracket 4011 includes a first fitting portion connected to the vertical portion 401, and a first extension portion extending along both ends of the first fitting portion toward the inner wall of the A-pillar 1 and connected to the A-pillar 1. Furthermore, the first connecting bracket 4011 such that the vertical portion 401 is spaced between the inner A-pillar panel and the outer A-pillar panel. (Combined with...) Figure 7 As shown, similar to the first connecting bracket 4011, the second connecting bracket 4021 also includes a second fitting portion connected to the transverse portion 402, and a second extension portion extending along both ends of the second fitting portion toward the inner wall of the sill beam 3 and connected inside the sill beam 3. Furthermore, the second connecting bracket 4021 causes the transverse portion 402 to be spaced apart from the sill beam 3.

[0074] As configured above, when the side structure of the vehicle body is impacted, the outer panels of the A-pillar 1 and the sill beam 3 undergo energy-absorbing deformation due to the impact. Since the first reinforcing member 4 is spaced between the A-pillar 1 and the sill beam 3, the outer panels of the A-pillar 1 and the sill beam 3 can have a larger deformation range, thereby absorbing more impact energy and reducing the impact energy transmitted to the first reinforcing member 4, thus helping to ensure the safety of the occupants inside the vehicle.

[0075] It is worth noting that, in combination Figures 4 to 6 As shown, multiple second connecting brackets 4021 are arranged at intervals, specifically 3, 4, 5, etc. The specific number can be determined according to the internal space of the door frame beam. As an example, in this embodiment, four second connecting brackets 4021 are provided. It can be understood that multiple first connecting brackets 4011 can also be provided, and the number of first brackets can also be determined according to the internal space size of column A1.

[0076] In some of the exemplary implementations, combined with Figure 1 , Figure 8 and Figure 9 As shown, the side structure of the vehicle body also includes a roof side beam 5 that connects the upper section 102 of the A-pillar 1 to the top of the B-pillar 2, and a second reinforcing member 6; the second reinforcing member 6 is "n" shaped and includes a first part 601 located in the upper section 102, a second part 602 located in the roof side beam 5, and a third part 603 located in the B-pillar 2.

[0077] Therefore, by setting a second reinforcing member 6 in the upper section 102 of A-pillar 1, the roof side beam 5, and the B-pillar 2, the structural strength between A-pillar 1, B-pillar 2, and roof side beam 5 can be increased by the second reinforcing member 6. At the same time, a roll cage structure can be formed between the upper parts of A-pillar 1 and B-pillar 2, which not only helps to distribute the collision force between A-pillar 1 and B-pillar 2, but also helps to improve the anti-roof crush performance of the side of the vehicle body, thus improving the overall collision safety of the vehicle.

[0078] Understandably, in specific implementation, the second reinforcing member 6 is "n" shaped, which mainly refers to the fact that the second reinforcing member 6 has a first part 601, a second part 602 and a third part 603 connected in sequence, and the second reinforcing member 6 is placed in the upper section 102, the top cover side beam 5 and the B column 2 to form an "n" shaped structure. Its main purpose is to enhance the structural strength of the upper section 102, the top cover side beam 5 and the B column 2, and to form a roll cage structure between the upper parts of the A column 1 and the B column 2.

[0079] In some of the exemplary implementations, combined with Figure 9 and Figure 10 As shown, the second reinforcing member 6 is integrally formed, and the second reinforcing member 6 adopts a hot air expansion tube.

[0080] Therefore, by making the second reinforcing member 6 integrally molded, it is easier to manufacture and the reliability of the connection between the first part 601, the second part 602 and the third part 603 can be guaranteed. At the same time, the use of hot gas expansion tube for the second reinforcing member 6 is also conducive to the cross-sectional design and molding of the second reinforcing member 6, and also helps to ensure the structural performance of the second reinforcing member 6.

[0081] In practical implementation, by using a hot-air expansion tube for the second reinforcing member 6, it is possible to ensure uniform deformation within the molding die during the forming process. This facilitates adjustment of the tube wall thickness of the second reinforcing member 6 and effectively ensures the continuity of the impact force transmission path during a collision. Furthermore, using a hot-air expansion tube for the second reinforcing member 6 allows it to conform to the upper section 102 of the A-pillar 1, the top cover side beam 5, and the B-pillar 2.

[0082] In some of the exemplary implementations, combined with Figures 8 to 10 As shown, the first part 601 is fixed in the upper section 102 by the third connecting bracket 6011, the second part 602 is fixed in the top cover side beam 5 by the fourth connecting bracket 6021, and the third part 603 is fixed in the B column 2 by the fifth connecting bracket 6031.

[0083] As described above, the first part 601 is fixed to the upper section 102 of the A-pillar 1 by the third connecting bracket 6011, the second part 602 is fixed to the top cover side beam 5 by the fourth connecting bracket 6021, and the third part 603 is fixed to the B-pillar 2 by the fifth connecting bracket 6031. This facilitates the fixed arrangement of the second reinforcing member 6 in the A-pillar 1, B-pillar 2 and the top cover side beam 5.

[0084] It is understandable that, as described above, while ensuring the secure connection of the second reinforcing member 6 within the A-pillar 1, B-pillar 2, and roof edge beam 5, the second reinforcing member 6 also simultaneously enhances the reliability of the connection between the A-pillar 1, B-pillar 2, and roof edge beam 5.

[0085] Continue to combine Figures 8 to 13 As shown, in some exemplary embodiments, the third connecting bracket 6011 is arranged near the bottom end of the first part 601 and extends along the length direction of the first part 601; the fourth connecting bracket 6021 consists of a plurality of brackets spaced apart along the length direction of the second part 602; the B-pillar 2 is provided with a hinge mounting plate 7; the fifth connecting bracket 6031 includes a lower bracket 60311 connected to the hinge mounting plate 7, the lower bracket 60311 is provided with a connecting hole 60312, the bottom end of the third part 603 is inserted into the connecting hole 60312, and the bottom end of the third part 603 and the lower bracket 60311 are fixedly connected together.

[0086] Based on the above overall description, the third connecting bracket 6011 in A-pillar 1 is positioned close to the bottom end of the first part 601 and extends along the length of the first part 601. This ensures the fixation of the first part 601 and helps transmit the impact force from A-pillar 1 to the first part 601. The arrangement of multiple third connecting brackets 6011 at intervals ensures the stability of the second part 602 within the roof side beam 5. The fifth connecting bracket 6031 in B-pillar 2 includes a lower bracket 60311 connected to the hinge mounting plate 7. The bottom end of the third part 603 is inserted into the connecting hole 60312 on the lower bracket 60311 and fixed together with it. This ensures the stability of the third part 603 within B-pillar 2 and helps disperse the impact force of the second reinforcing member 6 towards B-pillar 2.

[0087] In specific implementation, when the third connecting bracket 6011 is connected to the first part 601, the third connecting bracket 6011 conforms to the first part 601 and partially covers it. This arrangement effectively ensures the connection area between the third connecting bracket 6011 and the first part 601 while effectively increasing the deformation resistance of the first part 601 where the third connecting bracket 6011 is located. Furthermore, the third connecting bracket 6011 is close to the bottom end of the first part 601, thus reinforcing the bottom end of the first part 601. When the bottom of the first part 601 is impacted, it provides good deformation resistance.

[0088] It should also be noted that, in combination Figure 8 As shown, multiple fourth connecting brackets 6021 are arranged at intervals along the length of the second part 602. Specifically, there can be 2, 3, 4, etc. of fourth connecting brackets 6021. The specific number is determined according to the gap between the top cover side beam 5 and the second part 602. As an optional implementation, in this embodiment, there are 2 fourth connecting brackets 6021, and the two fourth connecting brackets 6021 are respectively located at both ends of the second part 602.

[0089] It is worth noting that, because the B-pillar 2 has a cavity, it includes an outer panel located outside the vehicle and an inner panel located inside the vehicle. In specific implementation, the hinge mounting plate 7 is located within the cavity of the B-pillar 2 and is fixedly connected to the outer panel. At this time, the lower bracket 60311 is fixedly connected to the top of the hinge mounting plate 7, and the side of the lower bracket 60311 closest to the inner panel extends towards and is fixedly connected to the inner panel, thus helping to improve the connection stability between the lower bracket 60311 and the B-pillar 2.

[0090] Understandably, the bottom end of the third part 603 is inserted into the connecting hole 60312, which can effectively restrict the radial movement of the bottom end of the third part 603. When the third part 603 is impacted, it can effectively prevent the bottom end of the third part 603 from bending into the vehicle, effectively ensuring the connection strength between the third part 603 and the B-pillar 2, and thus effectively ensuring the impact resistance of the B-pillar 2.

[0091] 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 13 As shown, it may include, for example, a pillar A1, a pillar B2, a sill beam 3 connected to the bottom of both pillar A1 and pillar B2, and a first reinforcing member 4; the first reinforcing member 4 is "L" shaped and includes a connected vertical portion 401 and a horizontal portion 402.

[0092] The vertical portion 401 is located within the lower section 101 of column A 1, and the top of the vertical portion 401 extends to near the top of the lower section 101. The horizontal portion 402 is located within the threshold beam 3, and the rear end of the horizontal portion 402 extends to near the bottom of column B 2.

[0093] Furthermore, the side structure of the vehicle body also includes a roof side beam 5 connecting the upper section 102 of the A-pillar 1 to the top of the B-pillar 2, and a second reinforcing member 6; the second reinforcing member 6 is "n" shaped, and the second reinforcing member 6 includes a first part 601 located in the upper section 102, a second part 602 located in the roof side beam 5, and a third part 603 located in the B-pillar 2.

[0094] Both the vertical portion 401 and the horizontal portion 402 adopt a tubular structure, and their inner cavities are connected. The first reinforcing member 4 and the second reinforcing member 6 are integrally formed, and both adopt a hot-expansion tube.

[0095] The vertical portion 401 and the horizontal portion 402 both have rectangular cross-sections; the cross-section of the vertical portion 401 is larger than that of the horizontal portion 402, and a transition section 403 with a gradually changing cross-section is formed at the connection position between the vertical portion 401 and the horizontal portion 402. The vertical portion 401 is fixed in the lower section 101 by a first connecting bracket 4011; and / or, the horizontal portions 402 are all fixed in the sill beam 3 by second connecting brackets 4021, and there are multiple second connecting brackets 4021 arranged at intervals along the extension direction of the horizontal portion 402.

[0096] The first part 601 is fixed to the upper section 102 via the third connecting bracket 6011, the second part 602 is fixed to the top cover side beam 5 via the fourth connecting bracket 6021, and the third part 603 is fixed to the B-pillar 2 via the fifth connecting bracket 6031. Specifically, the B-pillar 2 is provided with a hinge mounting plate 7, and the fifth connecting bracket 6031 includes a lower bracket 60311 connected to the hinge mounting plate 7. The lower bracket 60311 is provided with a connecting hole 60312, and the bottom end of the third part 603 is inserted into the connecting hole 60312, and the bottom end of the third part 603 is fixedly connected to the lower bracket 60311.

[0097] In the preferred embodiment of the above-mentioned vehicle side structure, the specific configuration and arrangement of the first reinforcing member 4, the second reinforcing member 6, the first connecting bracket 4011 and the second connecting bracket 4021, etc., 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 first reinforcing member 4 and the second reinforcing member 6, etc., can also be referred to the descriptions in the above-mentioned exemplary embodiments.

[0098] The side structure of the vehicle body in this embodiment adopts the above design. By setting a first reinforcing member 4 between the A-pillar 1 and the sill beam 3, the top of the vertical part 401 of the first reinforcing member 4 extends to the top near the lower section 101, and the rear end of the horizontal part 402 extends to the bottom near the B-pillar 2. This can increase the connection strength between the A-pillar 1 and the sill beam 3, and can also form a load-bearing structure and a through-type collision force transmission channel between the lower section 101 of the A-pillar 1 and the front part of the sill beam 3 during side and frontal collisions of the vehicle. This can achieve effective transmission of collision force, reduce collision deformation at the A-pillar 1 position, and help improve the safety of the whole vehicle in a collision.

The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
