[0049] The present application provides a body shotgun structure, and also provides a vehicle including the above body shotgun structure.

[0050] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0051] As Figures 1-7As shown in the figure, a body shotgun structure is a longitudinal beam for installing the front fender on a vehicle, located on the outermost side of the cab compartment, used to strengthen the support strength of the vehicle and for anti-collision buffering. Optionally, two body shotgun structures are symmetrically arranged along the width direction of the vehicle. The body shotgun structure includes a shotgun front beam 1, a shotgun rear beam 2, and a bracket assembly 3. The shotgun front beam 1 is a tubular structure, and the shotgun front beam 1 includes a first front end 11 and a first rear end 12 along its extending direction. The shotgun rear beam 2 includes a second front end 21 and a second rear end along its extending direction; the second front end 21 is fixedly connected to the first rear end 12. The bracket assembly 3 is fixed to the frame longitudinal beam 7, and the bracket assembly 3 includes a first bracket 31. Through the first bracket 31, a detachable hard connection of the first front end 11 of the shotgun front beam 1 on the first bracket 31 is realized, and thus a detachable hard connection of the body shotgun structure on the frame longitudinal beam 7 is realized.

[0052] It should be noted that the shotgun front beam 1 and the shotgun rear beam 2 form a shotgun beam body, and the shotgun beam body can also be named the upper longitudinal beam. The second rear end of the shotgun rear beam 2 can be connected to the vehicle A-pillar or to the vehicle floor cross beam.

[0053] The first bracket 31 can be made of sheet metal. The bracket assembly 3 can only include the first bracket 31, and at this time the first bracket 31 is directly fixed to the frame longitudinal beam 7; of course, in addition to including the first bracket 31, the bracket assembly 3 can also include other structural parts, and at this time the first bracket 31 is fixed to the frame longitudinal beam 7 through other structural parts included in the bracket assembly 3.

[0054] "Detachable" means that the first front end 11 can be fixedly connected to the first bracket 31 or can be detached from the first bracket 31. "Hard connection" means that the fixed connection between the first front end 11 and the first bracket 31 is a hard connection, that is, there is no elastic buffer at the connection between the first front end 11 and the first bracket 31, and the two are firmly rigidly connected together.

[0055] The shotgun front beam 1 of the present application is no longer formed by welding a plurality of stamped parts, but is formed by an integrally formed tubular structure, which is not only simple in structure, convenient and fast in processing and manufacturing, but also easy to control the size of the shotgun front beam 1 to meet the requirements of assembly dimensions during later assembly.

[0056] Further, the first bracket 31 realizes the fixed connection between the first front end 11 of the shotgun front beam 1 and the vehicle frame longitudinal beam 7. The connection between the first front end 11 and the vehicle frame longitudinal beam 7 is no longer a flexible connection but a rigid connection, which improves the bending and torsional stiffness / modes of the whole vehicle and enhances the handling stability performance and comfort. Moreover, the connection between the first front end 11 and the vehicle frame longitudinal beam 7 is a detachable connection, facilitating the disassembly, replacement, and repair of the shotgun front beam 1 on the vehicle frame longitudinal beam 7.

[0057] Please refer to the attached Figures 3-4 , in some embodiments of the present application, along the circumferential direction of the first front end 11, the first bracket 31 is formed with a first surrounding portion 311, and the first front end 11 is sleeved inside or outside the first surrounding portion 311.

[0058] Preferably, the first front end 11 is sleeved inside the first surrounding portion 311.

[0059] By providing the first surrounding portion 311, the fitting and docking effect of the first front end 11 in the circumferential direction is realized, ensuring the contact area between the first surrounding portion 311 and the first front end 11, and thus effectively ensuring the firmness and stability of the rigid connection between the two, avoiding shaking or detachment during use.

[0060] It should be noted that, in addition to being configured to include the first surrounding portion 311, the first bracket 31 can also be set in other forms. For example, the first bracket 31 includes a first connecting portion perpendicular to the axial direction of the first front end 11. Correspondingly, the first front end 11 is provided with a second connecting portion perpendicular to the axial direction of the first front end 11. Through the alignment and fitting connection of the first connecting portion and the second connecting portion, the rigid connection between the first front end 11 and the first bracket 31 is realized.

[0061] Please refer to the attached Figure 3 , the axial direction of the first front end 11, that is, the direction indicated by the arrow in the attached Figure 3 figure.

[0062] Please refer to the attached Figure 4 , in some embodiments of the present application, the first front end 11 is provided with a first assembly hole. The first surrounding portion 311 is provided with a second assembly hole adapted to the first assembly hole. The first fastener 4 passes through the first assembly hole and the second assembly hole respectively to realize the detachable connection of the first front end 11 on the first surrounding portion 311.

[0063] It should be noted that the first fastener 4 can be a fastening pin shaft or a fastening bolt.

[0064] As described above, the detachable connection between the first front end 11 and the first surrounding part 311 is realized conveniently and quickly, which facilitates the disassembly, replacement and repair of the shotgun front beam 1 on the first bracket 31. Moreover, the firmness and stability of the hard connection between the first front end 11 and the first surrounding part 311 can be ensured, thereby guaranteeing the firmness and stability of the hard connection of the shotgun front beam 1 on the first bracket 31, and the shotgun front beam 1 will not shake or separate relative to the first bracket 31.

[0065] It should be noted that, in addition to providing the first assembly hole on the first front end 11, the second assembly hole on the first surrounding part 311, and realizing the detachable connection between the two through the first fastener 4, other setting forms are also possible. For example, a clamping member capable of locking and closing along its own circumferential direction is provided. Along the axial direction of the first front end 11, the upper half of the clamping member is sleeved on the circumferential direction of the first front end 11, and the lower half of the clamping member is sleeved on the circumferential direction of the first surrounding part 311. The locking and fixing connection or the release of the locking and fixing between the first front end 11 and the first surrounding part 311 is realized by the locking and closing or the release of the locking and closing of the clamping member.

[0066] It should be further noted that, along the axial direction of the first front end 11, the aperture of the first assembly hole or the second assembly hole is larger than the outer diameter of the first fastener 4, so as to realize the adjustable position of the first front end 11 relative to the first surrounding part 311.

[0067] As described above, a certain adjustment margin is provided for the first front end 11 along its axial direction, which avoids the problem that the first front end 11 and the first surrounding part 311 cannot be assembled due to dimensional errors, compensates for the slight deviation of the component dimensions, and reduces the dependence on the machining accuracy.

[0068] Please refer to the appendix Figure 4 , in some embodiments of the present application, along the circumferential direction of the first front end 11, the first surrounding part 311 is a U-shaped structure. A plurality of second assembly holes are provided on each surrounding surface of the first surrounding part 311.

[0069] It should be noted that the first front end 11 can be sleeved inside the U-shaped first surrounding part 311 or outside the U-shaped first surrounding part 311.

[0070] Preferably, the first front end 11 is sleeved inside the U-shaped first surrounding part 311. Along the circumferential direction of the first front end 11, the U-shaped first surrounding part 311 realizes the three-sided covering of the first front end 11, ensuring the circumferential covering effect between the first surrounding part 311 and the first front end 11. Moreover, the U-shaped first surrounding part 311 also reserves an opening to facilitate the sleeving and disassembly of the first front end 11 on the first surrounding part 311, realizing the convenience of the assembly operation between the two.

[0071] Further, the first surrounding portion 311 of the U-shaped structure includes a first wall, a second wall and a third wall respectively located on opposite sides of the first wall; along the axial direction of the first front end 11, two second assembly holes are formed in the first wall, and one second assembly hole is formed in each of the first wall and the second wall. As described above, four installation points for the hard connection between the first surrounding portion 311 and the first front end 11 are realized, that is, through the combined fastening action of four first fasteners 4, the comprehensive, reliable and stable hard connection between the first surrounding portion 311 and the first front end 11 is achieved.

[0072] It should be noted that, in addition to being set as a U-shaped structure, the first surrounding portion 311 can also be set in other forms. For example, the first surrounding portion 311 is an annular structure to achieve the circumferential annular fitting effect on the first front end 11.

[0073] Please refer to the attached Figure 3 , in some embodiments of the present application, the bracket assembly 3 includes a second bracket 32 and a frame longitudinal beam bracket 33. The second bracket 32 is fixedly connected to the first bracket 31. The frame longitudinal beam bracket 33 is fixedly installed on the frame longitudinal beam 7 and is detachably connected to the second bracket 32.

[0074] It should be noted that the first bracket 31, the second bracket 32, and the frame longitudinal beam bracket 33 are all sheet metal structures. The bracket assembly 3 is divided into two groups, where the first bracket 31 and the second bracket 32 are one group, and the frame longitudinal beam bracket 33 is its own group.

[0075] The first bracket 31 is welded to the second bracket 32; further, the first bracket 31 and the second bracket 32 are connected by C02 welding (i.e., carbon dioxide shielded welding, which belongs to a type of arc welding. The metal is melted by the high temperature generated by the arc to achieve welding, and the C02 gas is used as a shielding gas to cover the arc and the molten pool to prevent oxygen and nitrogen in the air from entering the molten pool, avoiding oxidation and nitriding, and ensuring the quality of the weld). Further, the frame longitudinal beam bracket 33 is welded to the frame longitudinal beam 7 and is welded to one side of the frame longitudinal beam 7 along the vehicle width direction.

[0076] The frame longitudinal beam bracket 33 is fixed to the frame longitudinal beam 7, providing an installation position for installing other structural parts on the frame longitudinal beam 7; the first bracket 31 and the second bracket 32 are fixed as a whole, on the one hand, providing an installation position for connecting with the frame longitudinal beam bracket 33, and on the other hand, providing an installation position for connecting with the shotgun front beam 1. As described above, the hard connection between the shotgun front beam 1 and the frame longitudinal beam bracket 33 is conveniently and quickly realized, and further, the hard connection between the shotgun front beam 1 and the frame longitudinal beam 7 is conveniently and quickly realized.

[0077] Furthermore, the first bracket 31 and the second bracket 32 are provided in a split connection form, which not only facilitates the production and processing of each split component, but also can reduce the transportation and storage costs. The first bracket 31 and the second bracket 32 are fixed together and can be separated from the connection with the shotgun front beam 1 and the connection with the vehicle frame longitudinal beam bracket 33 respectively; as above, the first bracket 31 and the second bracket 32 with appropriate sizes can be selected and replaced according to actual needs to adapt to the size of the shotgun front beam 1 with specific requirements, and the flexibility and applicability are greatly improved.

[0078] Please refer to the appendix Figure 3 、 5 In some embodiments of the present application, the bracket assembly 3 further includes a first sleeve 34. Along the axial direction of the first front end 11, the vehicle frame longitudinal beam bracket 33 forms a receiving space, and the first sleeve 34 is fixed in the receiving space. The second fastener 5 sequentially passes through the first sleeve 34 and the second bracket 32 to realize the detachable connection between the vehicle frame longitudinal beam bracket 33 and the second bracket 32.

[0079] It should be noted that the first sleeve 34 has an internal threaded hole provided with internal threads. The vehicle frame longitudinal beam bracket 33 is a frame structure with a receiving space inside. Along the axial direction of the first sleeve 34, the vehicle frame longitudinal beam bracket 33 includes a bottom wall and a top wall. One end of the first sleeve 34 is fixed to the bottom wall and the other end is fixed to the top wall. The bottom wall and the top wall of the vehicle frame longitudinal beam bracket 33 are respectively provided with a first connection hole and a second connection hole; the first connection hole and the second connection hole are both communicated with the internal threaded hole of the first sleeve 34. The second bracket 32 is provided with a third connection hole communicated with the second connection hole.

[0080] It should be further noted that the second fastener 5 can be a fastening pin or a fastening bolt. When the second fastener 5 is a fastening bolt, the third connection hole provided on the second bracket 32 can be a threaded hole with internal threads to realize the screwing and fixing of the second fastener 5 on the second bracket 32; of course, the third connection hole provided on the second bracket 32 can also be a circular through hole, and a first connection nut 35 communicated with the third connection hole is provided on the second bracket 32 to realize the screwing and fixing of the second fastener 5 on the first connection nut 35.
