Description

Technical Field

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

[0002] In a vehicle, the side body generally consists of an inner side panel and an outer side panel. In some models, a side reinforcement panel is also provided. These panels are stacked and fastened together to form the skeletal structure of the side body, such as the A-pillar, B-pillar, and C-pillar.

[0003] Currently, to enhance the side impact resistance of a vehicle body, reinforcing plates are typically installed inside the A-pillar, B-pillar, and C-pillar structures, and these plates are all made of stamped sheet metal. Due to limitations in the stamping process, these reinforcing plates can only be made into sheet-like structures, which limits their reinforcing effect and fails to effectively improve the rigidity of the vehicle's side structure, thus hindering improvements in vehicle collision safety. Utility Model Content

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

[0017] Furthermore, the upper section of the B-pillar reinforcing tube is fixed inside the B-pillar by a first B-pillar connecting bracket, and the lower section of the B-pillar reinforcing tube is fixed inside the B-pillar by a second B-pillar connecting bracket.

[0018] The upper section and the lower section of the B-pillar reinforcing tube are connected together by a third B-pillar connecting bracket, which is fixed inside the B-pillar.

[0019] Furthermore, the first B-pillar connecting bracket includes a lower bracket disposed near the bottom end of the upper section of the B-pillar reinforcing tube;

[0020] The lower support has a flange hole in the middle and multiple connecting flanges on the edge of the lower support. The upper section of the B-pillar reinforcing tube is connected in the flange hole, and the lower support is fixed in the B-pillar through each of the connecting flanges.

[0021] Furthermore, the edge beam reinforcement assembly includes an edge beam reinforcement tube, the front end of which is connected to the A-pillar reinforcement assembly and the B-pillar reinforcement assembly, and the rear end of which is connected to the C-pillar reinforcement assembly; and / or,

[0026] The A-pillar reinforcement assembly, the B-pillar reinforcement assembly, and the C-pillar reinforcement assembly are all directly or indirectly connected to the connection stop.

[0027] Compared with related technologies, this application has the following advantages:

[0028] (1) The vehicle side structure described in this application, by setting up A-pillar reinforcement components, B-pillar reinforcement components, C-pillar reinforcement components and side beam reinforcement components using tubular beams, and setting a sill reinforcement part in the sill beam, and connecting the A-pillar reinforcement components, B-pillar reinforcement components, C-pillar reinforcement components and side beam reinforcement components and sill beam to form a frame structure, can effectively increase the structural strength and rigidity of the vehicle side by utilizing the good rigidity and strength characteristics of the frame structure composed of tubular and tubular beam structures, and improve the transmission and dispersion performance of collision force during vehicle collision, thereby effectively improving the collision safety of the vehicle.

[0029] (2) The A-pillar reinforcement tube extends from the bottom of the A-pillar to the top of the A-pillar. The A-pillar reinforcement tube is a one-piece molded structure, which can ensure the rigidity of the A-pillar reinforcement component, ensure the structural reinforcement effect of the A-pillar position, improve the A-pillar's ability to resist collision deformation, and help improve the safety of the vehicle in frontal collision.

[0030] (3) The A-pillar reinforcing tube is installed inside the A-pillar through the A-pillar connecting bracket, which facilitates the arrangement of the A-pillar reinforcing tube inside the A-pillar. This allows the second A-pillar connecting bracket to be installed close to the lower section of the A-pillar, and the first and second A-pillar connecting brackets are long strip structures extending along the length of the A-pillar reinforcing tube. This also allows the first and second A-pillar connecting brackets to be used to focus on reinforcing the parts of the A-pillar that bear the impact of a frontal collision, thereby better improving the A-pillar's ability to withstand collisions.

[0031] (4) The B-pillar reinforcing tube includes an upper section and a lower section of the B-pillar reinforcing tube connected together. The segmented arrangement of the B-pillar reinforcing tube facilitates its placement within the B-pillar, reduces the design and manufacturing difficulty of the vehicle body, and helps to reduce vehicle costs.

[0032] (5) The upper section of the B-pillar reinforcing tube is fixed inside the B-pillar via a first B-pillar connecting bracket, and the lower section of the B-pillar reinforcing tube is fixed inside the B-pillar via a second B-pillar connecting bracket, which facilitates the arrangement of the upper and lower sections of the B-pillar reinforcing tube within the B-pillar. The upper and lower sections of the B-pillar reinforcing tube are then connected via a third B-pillar connecting bracket, which is also fixed inside the B-pillar. This facilitates the connection between the upper and lower sections of the B-pillar reinforcing tube and, with the aid of the B-pillar structure, ensures the reliability of the connection between them.

[0033] (6) By setting flange holes and multiple connecting flanges on the lower bracket, and connecting the upper section of the B-pillar reinforcing tube in the flange holes, and connecting the lower bracket in the B-pillar through each connecting flange, the stability of the bottom end of the upper section of the B-pillar reinforcing tube in the B-pillar can be increased, which helps to ensure the reliability of the connection between the upper sections of the B-pillar reinforcing tube and the upper section of the B-pillar reinforcing tube.

[0034] (7) The front end of the side beam reinforcing tube is connected to the A-pillar reinforcing component and the B-pillar reinforcing component, and the rear end is connected to the C-pillar reinforcing component, which can ensure the structural effect of the side beam reinforcing component. The C-pillar reinforcing tube extends from the bottom end of the C-pillar to the top end of the C-pillar. It can take advantage of the integral molding structure of the C-pillar reinforcing tube to ensure the rigidity of the C-pillar reinforcing component, ensure the structural reinforcement effect of the C-pillar position, improve the C-pillar's ability to resist collision deformation, and help improve the safety of the vehicle in rear-end collisions.

[0035] (8) The A-pillar reinforcement assembly, B-pillar reinforcement assembly, and side beam reinforcement assembly are connected together via the first connecting bracket, which facilitates the connection between the A-pillar reinforcement assembly, B-pillar reinforcement assembly, and side beam reinforcement assembly, thereby reducing the design and assembly costs of the vehicle body. The side beam reinforcement assembly and C-pillar reinforcement assembly are connected together via the second connecting bracket, which also facilitates the connection between the side beam reinforcement assembly and C-pillar reinforcement assembly, thereby reducing the design and assembly costs of the vehicle body.

[0036] (9) A connecting stop is provided at the top of the sill beam, which is composed of the inner sill plate and the outer sill plate. This allows the A-pillar reinforcement assembly, B-pillar reinforcement assembly and C-pillar reinforcement assembly to be connected to the connecting stop. This facilitates the connection between the A-pillar reinforcement assembly, B-pillar reinforcement assembly and C-pillar reinforcement assembly and the sill beam, which helps to reduce the design, manufacturing and assembly costs of the vehicle body. At the same time, it can also ensure the effective connection between the A-pillar reinforcement assembly, B-pillar reinforcement assembly and C-pillar reinforcement assembly and the sill reinforcement part, which can better ensure the rigidity of the frame structure.

[0037] This application also proposes a vehicle having a body side structure as described above.

[0038] The vehicle described in this application, by setting the side structure of the vehicle body as described above, can effectively increase the structural strength and rigidity of the side of the vehicle body, and improve the transmission and dispersion performance of collision force during vehicle collision, which helps to improve the collision safety of the vehicle and has good practicality.

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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] An embodiment of the first aspect of this application provides a vehicle side structure that increases the structural rigidity of the vehicle side by providing reinforcing components in the A-pillar 1, B-pillar 2, C-pillar 3 and roof side beam 4, and providing a sill reinforcement 10 at the sill beam 5, thereby effectively improving the safety of vehicle collisions.

[0073] In related technologies, to increase the ability of the vehicle body to cope with side collisions, the traditional method is to install reinforcing plates inside the A-pillar 1, B-pillar 2 and other structures. The reinforcing plates are usually made of stamped sheet metal parts and are installed inside the A-pillar 1, B-pillar 2 and C-pillar 3 and other structures by welding.

[0074] However, due to the limitations of the stamping process, the reinforcing plates can only be made into sheet structures, which results in limited reinforcement effects and cannot effectively improve the rigidity of the vehicle body side, thus hindering the effective improvement of vehicle collision safety.

[0075] In view of this, in order to overcome the shortcomings of related technologies, the vehicle side structure of this embodiment combines... Figures 1 to 3 As shown, the overall design includes an A-pillar reinforcement component 6 installed in the A-pillar 1, a B-pillar reinforcement component 7 installed in the B-pillar 2, a C-pillar reinforcement component 8 installed in the C-pillar 3, and a side beam reinforcement component 9 installed in the roof side beam 4.

[0076] Among them, the A-pillar reinforcement component 6, B-pillar reinforcement component 7, C-pillar reinforcement component 8 and side beam reinforcement component 9 each include at least one section of pipe beam, and the A-pillar reinforcement component 6, B-pillar reinforcement component 7, C-pillar reinforcement component 8 and side beam reinforcement component 9 are connected to the sill beam 5 to form a frame structure.

[0077] In addition, the sill beam 5 includes an inner sill plate 501 and an outer sill plate 502 that are fastened together, and the connected inner sill plate 501 and outer sill plate 502 together form a tubular sill reinforcement 10, which extends from the front end of the sill beam 5 to the rear end of the sill beam 5.

[0078] Therefore, by setting up A-pillar reinforcement components 6, B-pillar reinforcement components 7, C-pillar reinforcement components 8 and side beam reinforcement components 9 using tubular beams, and setting a sill reinforcement part 10 in the sill beam 5, and connecting the A-pillar reinforcement components 6, B-pillar reinforcement components 7, C-pillar reinforcement components 8, side beam reinforcement components 9 and sill beam 10 to form a frame structure, this embodiment can utilize the good rigidity and strength characteristics of the frame structure composed of tubular and tubular beam structures to effectively increase the structural strength and rigidity of the side of the vehicle body, and improve the transmission and dispersion performance of collision force during vehicle collision, thereby effectively improving the vehicle collision safety.

[0079] Based on the above general introduction, specifically, given that the body structure on the left and right sides of a vehicle is generally designed symmetrically, this embodiment will specifically use one side as an example for explanation.

[0080] Continue as Figure 4 and Figure 5 As shown in the illustration, in some exemplary embodiments, the sill beam 5 also has a connecting stop 5a located at the top of the sill reinforcement 10. The connecting stop 5a is composed of the inner sill plate 501 and the outer sill plate 502, and extends from the front end of the sill beam 5 to the rear end of the sill beam 5. Furthermore, the aforementioned A-pillar reinforcement component 6, B-pillar reinforcement component 7, and C-pillar reinforcement component 8 are all directly or indirectly connected to the connecting stop 5a.

[0081] In this way, by setting a connecting stop 5a at the top of the sill beam 1, which is composed of the inner sill plate 501 and the outer sill plate 502, the A-pillar reinforcement component 6, the B-pillar reinforcement component 7, and the C-pillar reinforcement component 8 can be connected to the connecting stop 5a. This facilitates the connection between the A-pillar reinforcement component 6, the B-pillar reinforcement component 7, and the C-pillar reinforcement component 8 and the sill beam 5, which helps to reduce the design, manufacturing, and assembly costs of the vehicle body. At the same time, it is understandable that, since the connecting stop 5a is also composed of the inner and outer sill plates, it can also ensure the effective connection between the A-pillar reinforcement component 6, the B-pillar reinforcement component 7, and the C-pillar reinforcement component 8 and the sill reinforcement part 10. This allows the tubular beam and tubular structure in the above-mentioned frame structure to be effectively connected together, thereby better ensuring the rigidity and strength of the frame structure.

[0082] It is worth noting that the inner sill plate 501 and the outer sill plate 502 are generally connected together by welding after being snapped together. The tubular sill reinforcement 10 composed of the snapped inner sill plate 501 and the outer sill plate 502 can have a cross-sectional shape that is as close to a circle as possible. This allows the tubular sill reinforcement 10 to have better structural performance.

[0083] In addition to the connecting stop 5a at the top, in specific implementation, the sill beam 5 may also have a lower stop 5b at the bottom. The lower stop 5b can generally be composed of the inner sill plate 501 and the outer sill plate 502.

[0084] In addition, to facilitate the connection between the sill beam 5 and the A-pillar reinforcement component 6, the connecting stop 5a can be extended forward at the front end of the sill beam 5 to form an extension end t, which can be specifically connected to the A-pillar reinforcement component 6.

[0085] In addition, as before Figure 1 and Figure 2As shown, in this embodiment, based on the inclusion of the inner sill plate 501 and the outer sill plate 502, a side panel can generally be provided on the side of the outer sill plate 502 facing outwards at the sill beam 5 position. This allows for the use of a multi-layer structure to better ensure the structural performance at the sill beam 5 position.

[0086] Continue to combine Figures 6 to 9 As shown in this embodiment, in some exemplary implementations, the A-pillar reinforcement component 6 specifically includes an A-pillar reinforcement tube 601, which extends from the bottom end of the A-pillar 1 to the top end of the A-pillar 1. The bottom end of the A-pillar reinforcement tube 601 is connected to the sill beam 5, and its top end is connected to the B-pillar reinforcement component 7 and the side beam reinforcement component 9.

[0087] At this point, by extending the A-pillar reinforcing tube 601 from the bottom end of the A-pillar 1 to the top end of the A-pillar 1, it can be understood that by utilizing the integral molding structure of the A-pillar reinforcing tube 601, the rigidity of the A-pillar reinforcing component 6 can be guaranteed, the structural reinforcement effect on the A-pillar 1 can be guaranteed, and the ability of the A-pillar 1 to resist collision deformation can be improved, which is conducive to improving the safety of the vehicle in frontal collision.

[0088] Based on the above-described A-pillar reinforcing tube 601, in some exemplary embodiments, the A-pillar reinforcing tube 601 of this embodiment can be fixed inside the A-pillar 1, for example, by an A-pillar connecting bracket 602.

[0089] The A-pillar connecting bracket 602 may include, for example, a first A-pillar connecting bracket 6021 located within the lower section 101 of the A-pillar, and a second A-pillar connecting bracket 6022 and a third A-pillar connecting bracket 6023 located within the upper section 102 of the A-pillar. Preferably, in its arrangement, the second A-pillar connecting bracket 6022 is positioned close to the lower section 101 of the A-pillar. Structurally, it is preferable that the first A-pillar connecting bracket 6021 and the second A-pillar connecting bracket 6022 are elongated strip structures extending along the length of the A-pillar reinforcing tube 601.

[0090] Therefore, the A-pillar reinforcing tube 601 is installed inside the A-pillar 1 via the A-pillar connecting bracket 602, which facilitates the arrangement of the A-pillar reinforcing tube 601 within the A-pillar 1. Furthermore, the second A-pillar connecting bracket 6022 is positioned close to the lower section 101 of the A-pillar, and both the first and second A-pillar connecting brackets 6021 and 6022 are elongated strip structures extending along the length of the A-pillar reinforcing tube 601. This allows for focused reinforcement of the portion of the A-pillar 1 that bears the impact of a frontal collision (i.e., near the bending point at the front of the A-pillar 1), thereby better enhancing the A-pillar 1's ability to withstand collisions.

[0091] It should be noted that, in addition to making the first A-pillar connecting bracket 6021 and the second A-pillar connecting bracket 6022 both long strip structures extending along the length direction of the A-pillar reinforcing tube 601, in specific implementation, it is also possible to make the first A-pillar connecting bracket 6021 or the second A-pillar connecting bracket 6022 long strip structures, as long as they can meet the structural reinforcement requirements of the A-pillar 1.

[0092] Furthermore, the aforementioned third A-pillar connecting bracket 6023 can be installed near the top cover side beam 4, for example, to ensure the stability of the upper part of the A-pillar reinforcing tube 601 within the A-pillar 1. Also, see... Figures 7 to 9 As shown, each of the above-mentioned A-pillar connecting brackets 602 can be made of conventional stamped sheet metal parts, and each A-pillar connecting bracket 602 can also be connected to the A-pillar 1 body structure (such as the A-pillar inner plate or A-pillar reinforcing plate, etc.) and the A-pillar reinforcing tube 601 by welding.

[0093] In this embodiment, as Figures 10 to 13 As shown, in some exemplary embodiments, the B-pillar reinforcement component 7 specifically includes a B-pillar reinforcement tube 701, which also includes an upper section 7011 and a lower section 7012.

[0094] The top end of the upper section 7011 of the B-pillar reinforcing tube is connected to the A-pillar reinforcing component 6 and the side beam reinforcing component 9. The bottom end of the upper section 7011 of the B-pillar reinforcing tube is connected to the top end of the lower section 7012 of the B-pillar reinforcing tube, and the bottom end of the lower section 7012 of the B-pillar reinforcing tube is connected to the sill beam 5.

[0095] At this point, the B-pillar reinforcing tube 701 includes a connected upper section 7011 and a lower section 7012. The segmented arrangement of the B-pillar reinforcing tube 701 facilitates its placement within the B-pillar 2, reduces the design and manufacturing difficulty of the vehicle body, and helps to reduce vehicle costs.

[0096] In specific implementations, in some exemplary embodiments, the upper section 7011 of the B-pillar reinforcing tube can be fixed inside the B-pillar 2, for example, by a first B-pillar connecting bracket 703, while the lower section 7012 of the B-pillar reinforcing tube can be fixed inside the B-pillar 2, for example, by a second B-pillar connecting bracket 704. Furthermore, the upper section 7011 and the lower section 7012 of the B-pillar reinforcing tube are connected together, for example, by a third B-pillar connecting bracket 705, and this third B-pillar connecting bracket 705 is fixed inside the B-pillar 2.

[0097] Thus, by fixing the upper section 7011 of the B-pillar reinforcement tube within the B-pillar 2 through the first B-pillar connection bracket 703 and fixing the lower section 7012 of the B-pillar reinforcement tube within the B-pillar 2 through the second B-pillar connection bracket 704, it is convenient to arrange the upper section 7011 and the lower section 7012 of the B-pillar reinforcement tube within the B-pillar 2.

[0098] Of course, connecting the upper section 7011 and the lower section 7012 of the B-pillar reinforcement tube through the third B-pillar connection bracket 705 and fixing the third B-pillar connection bracket 705 within the B-pillar 2 as well is conducive to achieving the connection between the upper section 7011 and the lower section 7012 of the B-pillar reinforcement tube. At the same time, it can also rely on the body structure of the B-pillar 2 (i.e., the inner panel and reinforcement plate of the B-pillar, etc.) to ensure the reliability of the connection between the upper section 7011 and the lower section 7012 of the B-pillar reinforcement tube.

[0099] In this embodiment, in some specific exemplary implementation forms, the above-mentioned first B-pillar connection bracket 703 may, for example, include a lower bracket 7032 disposed near the bottom end of the upper section 701 of the B-pillar reinforcement tube. Structurally, a flanging hole 70321 is provided in the middle of the lower bracket 7032, and at the same time, a plurality of connecting flanges 70322 are also provided at the edge of the lower bracket 7032.

[0100] The bottom of the upper section 701 of the B-pillar reinforcement tube is connected in the flanging hole 70321, and the lower bracket 7032 is also fixed within the B-pillar 2 through the respective connecting flanges 70322 thereon.

[0101] In this way, by providing the flanging hole 70321 and the plurality of connecting flanges 70322 on the lower bracket 7032, connecting the upper section 7011 of the B-pillar reinforcement tube in the flanging hole 70321, and connecting the lower bracket 7032 within the B-pillar 2 through the respective connecting flanges 70322, it can increase the stability of the bottom end of the upper section 7011 of the B-pillar reinforcement tube within the B-pillar 2, contribute to ensuring the reliability of the connection between the upper section 7011 and the upper section 7012 of the B-pillar reinforcement tube, and enable the top pressure and the like received by the upper section 7011 of the B-pillar reinforcement tube to be effectively transmitted to the lower section 7012 of the B-pillar reinforcement tube.

[0102] It should be noted that still as Figure 10 and Figure 11 shown, in addition to including the above-mentioned lower bracket �032, in specific implementation, the above-mentioned first B-pillar connection bracket 703 generally may also include an upper bracket 7031 located above the lower bracket 7032. The upper bracket 7031 fixes the upper part of the upper section 7011 of the B-pillar reinforcement tube within the B-pillar 2. At the same time, as shown in Figure 11 the upper bracket 7031 can adopt a sheet metal bracket structure in the shape of a "U" and can also be set in the same way by welding.

[0103] In addition, see also Figure 12 In specific implementation, the lower bracket 7032 can also be a stamped sheet metal bracket, and for example, connecting flanges 70322 can be provided at each side edge of the lower bracket 7032. During connection, the edge of the flange hole 70321 can be connected to the upper section 7011 of the B-pillar reinforcing tube by welding, and the connection between each connecting flange 70322 and the main body structure of the B-pillar 2 can be achieved by welding.

[0104] Furthermore, in specific implementations, the aforementioned second B-pillar connecting bracket 704 can, for example, adopt a structure similar to the aforementioned upper bracket 7031. See also... Figure 13 In specific implementation, the aforementioned third B-pillar connecting bracket 705 can, for example, adopt a sheet metal bracket structure with flanged structures on two opposite sides. Furthermore, the third B-pillar connecting bracket 705 can be connected to the main body structure of B-pillar 2, as well as to the upper section 7011 and lower section 7012 of the B-pillar reinforcing tube, by means of welding.

[0105] In this embodiment, we continue to combine Figure 14 As shown, in some exemplary embodiments, the C-pillar reinforcement component 8 specifically includes a C-pillar reinforcement tube 801, which extends from the bottom end of the C-pillar 3 to the top end of the C-pillar 3. The bottom end of the C-pillar reinforcement tube 801 is connected to the side beam reinforcement component 9, and the bottom end of the C-pillar reinforcement tube 801 is connected to the sill beam 5. The C-pillar reinforcement tube 801 can be fixed inside the C-pillar 3 by the C-pillar connecting bracket 802.

[0106] At this point, the C-pillar reinforcing tube 801 extends from the bottom end of the C-pillar 3 to the top end of the C-pillar 3. Obviously, it can also utilize the characteristic of the C-pillar reinforcing tube 801 being an integrally formed structure to ensure the rigidity of the C-pillar reinforcing component 8, ensure the structural reinforcement effect at the C-pillar 3 position, improve the C-pillar 3's ability to resist collision deformation, and help improve the safety of the vehicle in a rear-end collision.

[0107] Continue to combine Figure 15 As shown, in some exemplary embodiments, the aforementioned side beam reinforcement component 9 specifically includes a side beam reinforcement tube 901. The front end of the side beam reinforcement tube 901 is connected to the A-pillar reinforcement component 6 and the B-pillar reinforcement component 7, and its rear end is connected to the C-pillar reinforcement component 8. The side beam reinforcement tube 901 can be connected to the top cover side beam 4 through the side beam connecting bracket 902.

[0108] At this point, it is understandable that connecting the front end of the edge beam reinforcing tube 901 to the A-column reinforcing component 6 and the B-column reinforcing component 7, and connecting the rear end to the C-column reinforcing component 8, can also ensure the structural effect of the edge beam reinforcing component 9.

[0109] In specific implementation, it should be noted that the above C-column connection bracket 802 and side beam connection bracket 902 generally can also adopt a "C"-shaped sheet metal bracket structure, and their connection can also be achieved by welding.

[0110] In this embodiment, in some exemplary implementation forms, it is still composed of Figure 1 , Figure 3 , and in combination with Figure 16 shown, the above A-column strengthening component 6, B-column strengthening component 7, and side beam strengthening component 9 can be connected together by, for example, the first connection bracket 11. And, a part of the first connection bracket 11 is located inside the roof side rail 4, and the other part is located inside the A-column 1.

[0111] In this way, the A-column strengthening component 6, B-column strengthening component 7, and side beam strengthening component 9 are connected together by the first connection bracket 11, which facilitates the connection between the A-column strengthening component 6, B-column strengthening component 7, and side beam strengthening component 9, and can reduce the design and assembly costs of the vehicle body.

[0112] In specific implementation, the above A-column strengthening component 6, B-column strengthening component 7, and side beam strengthening component 9 can be connected together by the first connection bracket 11, that is, the A-column strengthening tube 601, the upper section of the B-column strengthening tube 7011, and the side beam strengthening tube 901 are connected together by the first connection bracket 11.

[0113] At the same time, the above first connection bracket 11 generally can also adopt a stamping sheet metal bracket structure and is connected to each strengthening tube, the A-column 1, and the roof side rail 4 by welding. And in order to facilitate the connection between the first connection bracket 11 and each strengthening tube, further, for example, an A-column strengthening tube connection groove 1101, a B-column strengthening tube connection groove 1102, and a first side beam strengthening tube connection groove 1103 can also be provided on the first connection bracket 11. When connecting, each strengthening tube is embedded into the corresponding connection groove and then welded.

[0114] It is still composed of Figure 1 , Figure 3 , and in combination with Figure 17 shown, in this embodiment, in some exemplary implementation forms, the above side beam strengthening component 9 and C-column strengthening component 8 can also be connected together by the second connection bracket 12, and the second connection bracket 12 is located inside the roof side rail 4.

[0115] In this way, the side beam strengthening component 9 and C-column strengthening component 8 are connected together by the second connection bracket 12, which can also facilitate the connection between the side beam strengthening component 9 and C-column strengthening component 8, and reduce the design and assembly costs of the vehicle body.

[0116] Meanwhile, the second connecting bracket 12 can also adopt a stamped sheet metal bracket structure and be connected to each reinforcing tube, C-pillar 3, and top cover side beam 4 by welding. Furthermore, to facilitate the connection between the second connecting bracket 12 and each reinforcing tube, a second side beam reinforcing tube connecting groove 1201 and a C-pillar reinforcing tube connecting groove 1202 can also be provided on the second connecting bracket 12. During connection, each reinforcing tube is also embedded into the corresponding connecting groove, and then welded.

[0118] Among them, the A-pillar reinforcement component 6, B-pillar reinforcement component 7, C-pillar reinforcement component 8, and side beam reinforcement component 9 are connected to the sill beam 5 to form a frame structure. The A-pillar reinforcement component 6 includes an A-pillar reinforcement tube 601, the B-pillar reinforcement component 7 includes a B-pillar reinforcement tube 701 composed of an upper section 7011 and a lower section 7012 of the B-pillar reinforcement tube, the C-pillar reinforcement component 8 includes a C-pillar reinforcement tube 801, and the side beam reinforcement component 9 includes a side beam reinforcement tube 901. At the same time, the sill beam 5 is provided with a tubular sill reinforcement part 10 composed of an inner sill plate 501 and an outer sill plate 502.

The bottom ends of the A-column reinforcing tube 601 and C-column reinforcing tube 801 can be directly connected to the connecting stop 5a. The bottom end of the B-column reinforcing tube 701 can be connected to the connecting stop 5a through the connecting plate 706.

[0120] Among them, the A-pillar reinforcing tube 601, the B-pillar reinforcing tube 701 and the side beam reinforcing tube 901 can be connected by the first connecting bracket 11, and the side beam reinforcing tube 901 and the C-pillar reinforcing tube 801 can be connected by the second connecting bracket 12.
